An adult male greater bulldog bat (Noctilio leporinus) was found dead in a suburban area in the municipality of Patos, Paraiba, northeastern Brazil. At post-mortem examination, the bat was emaciated and had multifocal to coalescent grey, crusted, dry, scaly cutaneous lesions, irregularly distributed over the dorsal thoracoabdominal region, muzzle, labial commissures, ears and dorsoventral surfaces of the patagia. Histopathology revealed numerous longitudinal and transverse sections of fungal organisms, with weakly basophilic walls, associated with multifocal areas of ulceration of the epidermis, necrosis, rupture and discontinuity of collagen fibres in the dermis without any inflammatory response. Molecular identification matched the organism to Cladosporium spp, Curvularia spp, Exserohilum spp, Bipolaris spp (100%) and Alternaria spp (97%), all of which have been associated with phaeohyphomycosis. Phaeohyphomycosis should be included as a differential diagnosis of cutaneous lesions in chiropterans. [ABSTRACT FROM AUTHOR]

Diabetic neuroosteoarthropathy (Charcot’s osteoarthropathy, DNAP, Charcot’s foot) is a common complication of diabetic neuropathy, which can be easily diagnosed in clinical practice and usually is corrected without leading to severe deformation of the affected joint in case of timely and adequate treatment. We present the result of long-term clinical observation of a patient with early development of complications of type 2 diabetes mellitus, diabetic dermatopathy, common DNOAP with damage to the joints of the feet, ankles, knees and elbows. A feature of the described clinical case is the prevalence of osteoarticular disorders with seizure of atypical diabetes zones – knee and elbow joints, the defeat of which is more characteristic of other diseases (such as collagenoses and syphilis), as well as a combination of DNOAP with diabetic dermatopathy. It seems that the causes of such a common arthropathic process lie in the long course of diabetic neuropathy, which debuted long before the diagnosis of type 2 diabetes, as well as the development and progression of this patient in the last decade of observing diabetic nephropathy and associated secondary hyperparathyroidism. In the modern literature, descriptions of combinations of dermatopathies with other complications of diabetes mellitus are extremely rare, and references to a combination of common DNAP and diabetic bullosis have not been found.

- Abstract
Background: Melanoma is a malignant neoplasm that arises from melanocytes and malanoblasts. It is also more frequently reported in dogs than in other species. They may arise from melanocytes in the skin, on the surfaces of the mucous membranes, and eyes. The aim of this study was to describe the epidemiological aspects, risk factors and clinicopathological findings of melanoma in dogs in the backlands, northeastern Brazil. Materials, Methods & Results: A retrospective study was carried out in all biopsy samples and necropsy examinations of dogs, from January 2003 to December 2021, at the Animal Pathology Laboratory of the Federal University of Campina Grande, Patos, Paraiba, northeastern Brazil. Epidemiological data, clinical signs, and gross lesions were reviewed from the diagnostic laboratory reports. Samples of the skin, lymph nodes, central nervous system and organs of the thoracic and abdominal cavities were fixed in 10% buffered formalin, processed routinely for histopathology, embedded in paraffin wax, cut into 4 µm sections, and stained with hematoxylin and eosin (HE). Histological sections were also submitted to immunohistochemistry with the primary antibody anti-Melan A. Of the 4717 records found, 1158 (24.5%) were diagnosed with neoplasms, of which 48 (4.14%) cases were of melanoma. Of this total, 28 (58.3%) dogs were elderly, 19 (39.6%) were adults, and 1 (2.1%) was young. Mixed breed animals were the most affected (42.6%), followed by the pinscher breed (19.1%). According to the anatomical region, the most affected site was the skin (38/53=71.7%), followed by the oral cavity (12/53=22.65%) and the eyes (3/53=5.7%). Grossly, the skin lesions were characterized by exophytic and usually blackened, sometimes irregular and firm, nodules. At cut, they had a smooth, compact and blackened surface. Lesions in the oral cavity were characterized by blackened, irregular and infiltrating nodules or masses. The ocular lesions were always unilateral and were characterized by an enlarged and diffusely blackened eyeball, with areas of ulceration and subversion of tissue architecture. In 5 animals there was more than one anatomical site affected, totaling 53 lesions. In 9 (17%) cases, metastases were identified, 8 in regional lymph nodes and 1 in the lung. Histopathology showed a densely non-encapsulated, poorly delimited, expansive and infiltrative neoplasm, composed of neoplastic cells arranged in islands or nests and supported by fibrovascular stroma, containing a variable amount of brownish pigment (melanin). Immunohistochemistry showed strong immunostaining of the neoplastic cells in brown by the anti-Melan A antibody. Discussion: The diagnosis of melanoma was established based on epidemiological, clinical, anatomopathological, and immunohistochemical findings. Gender is not a predisposing factor, and although there was no statistically significant relationship, males were more affected. Senescence is a conditioning risk factor. Elderly animals were more affected (P < 0.0001) than adult ones, with OR = 4.38; and young ones (P = 0.0051), with OR = 12.65. Some breeds, especially those with marked skin pigmentation, were more affected, however the most affected ones in this survey were pinscher and poodle. Cutaneous melanoma accounted for almost 72% of cases, contesting recent studies where oral cavity melanoma was more frequent. Therefore, it is believed that the climatic conditions of the backlands sub-region, in northeastern Brazil, associated with the individual characteristics of the dogs, are involved in the development of these neoplasms, since the climate is predominantly dry, with high temperatures throughout the year, with maximums that can reach 40ºC, favoring the exposure to high incidence of ultraviolet radiatio [ABSTRACT FROM AUTHOR]

Pythiosis is commonly associated with humid and swampy tropical environments. It is considered a pyogranulomatous disease, which in equines mainly affects the skin and subcutaneous tissue. It occurs most frequently in the limbs, face and abdominal region. To the veterinary clinic of the Remington University Corporation is presented an equine of female sex, pinto coat, with an age of eleven years. The patient arrives on the occasion of consultation of a lesion present at the ventral abdominal level, which is granulomatous, ulcerative and apparently necrotic. It presents a lot of purulent discharge active and continuous with several fistulous tracts. To the washing of the wound the presence of structures compatible with Kunkers is evidenced. The diagnostic plan includes blood count and basic blood chemistry. A swab of the wound is sent in order to evaluate the bacterial growth in the culture and the antibiogram. At the therapeutic level, treatment starts with Veterflucina® (composed of penicillin G, streptomycin, flumetasone) and metronidazole locally. Infiltrations are performed in the lesion with Kenacort® (triamcinolone acetate). The response to the treatment established is partially effective, which is why it is decided to perform the surgical removal of the wound by removing a structure with a length of 15 cm long, 7 cm wide and weighing 300 grams. The animal responds satisfactorily to surgery and to date it has not shown recurrence of the pathology. [ABSTRACT FROM AUTHOR]

ABSTRACT: Canine atopic dermatitis (CAD) is a pruritic, chronic inflammatory disease, recurrent and genetically predisposed, which is the second most frequent allergic skin disorder, and ranks second among all the causes of pruritus in dogs worldwide. Given the absence of data on the occurrence of CAD in the northern region of Brazil, the aim of the current study was to conduct a survey to define the prevalence of canine atopic dermatitis attended at the Dermatology Department of the Mário Dias Teixeira Veterinary Hospital of the “Universidade Federal Rural da Amazônia” (HOVET-UFRA). To determine the prevalence of CAD, a retrospective survey was carried out of clinical records and results of dermatological examinations conducted at the Dermatology Department of HOVET-UFRA Belém, Pará from October 2018 to October 2019. During this period, 456 dogs were examined, of which 25.65% (117) were diagnosed with atopic dermatitis. Among the animals diagnosed, 62.4% (73) were females and 51.7% (29) were of the Shih-tzu breed. This level of atopic dermatitis is considered high. There are still no exact data on the incidence and prevalence of this dermatopathy, with described occurrence ranging from 3 to 15% of the canine population, a geographical relationship may be present. Although a sex-related predisposition has not been proven, a higher incidence of atopy in females is described, which indicated this may be the case. The most commonly diagnosed dogs in this study were the Shih-tzu breed. It is suspected that the regional popularity of some breeds, or the different genetic backgrounds in different geographical areas, may affect the predominance of CAD in some breeds. The results of the present study demonstrate the need for more research on the prevalence of canine atopic dermatitis, and better means of characterizing the population of atopic dogs in the region, so that it is possible to obtain a reliable epidemiological profile.

Abstract Leishmania infantum is a trypanosomatid that causes parasitic dermatopathy in dogs. Trypanosoma caninum is another trypanosomatid, which infects the skin of dogs, although cutaneous abnormalities are absent. This study aimed to investigate the occurrence of T. caninum infection and its associated cutaneous and histological changes and compare it with the occurrence of L. infantum infection in dogs. The study included 150 dogs, of which T. caninum infection was identified in 3 (2%) and L. infantum infection in 15 (10%) of them, with no association (p>0.05) of these infections with the breed, gender, age, or cutaneous abnormalities. The cutaneous abnormalities were based on 1 (4.8%) and 12 (57.1%) dogs infected by T. caninum and L. infantum, respectively. The dermatohistopathological abnormalities in the dogs infected with T. caninum included mild perivascular lymphohistioplasmacytic infiltrates in the clinically asymptomatic ones, while in those with dermatological abnormalities, acanthosis, epidermal orthokeratotic hyperkeratosis, melanomacrophages, and co-infection with Microsporum sp. and Trichophyton sp. were observed. InL. infantum infected, the histopathological findings included chronic granulomatous inflammatory infiltrates and structures compatible with amastigotes. Despite the low frequency of T. caninum infection, our findings suggest that this trypanosomatid, unlike L. infantum, does not cause any macroscopic skin abnormalities.

The aim of this study was to report a case of pyotraumatic dermatitis in an adult canine that was treated without the use of antimicrobials associated to laser therapy. An 8-year-old male dog with skin lesions, alopecia, and severe oily seborrhoea was referred for clinical care. In the clinical evaluation, the animal presented normal parameters for the species, however due to the lesions presented, cytopathological and parasitological skin examinations were requested, which evidenced the presence of an infectious inflammatory process, suggestive of bacteria, at the cytopathological examination, and Demodex canis in the parasitological assay. The proposed treatment consisted of baths with shampoo based on chlorhexidine with miconazole, supplements based on vitamins and minerals, antiparasitic, oral glucocorticoid and later topical, omega 3 and immunostimulant, in addition to a phototherapy session. On the last return, the animal presented the remade hair. Pyotraumatic dermatitis, despite being easy to diagnose, requires full attention regarding the individualized response of each animal to the condition. In this case, the constant monitoring performed by the veterinarian, provided the establishment of the most appropriate therapeutic approach to solve the problem and restore the animal's health without the use of antimicrobials, and with the additional laser therapy.

Trichophyton rubrum is rarely isolated from dogs with dermatophytosis. It is an anthropophilic dermatophyte commonly causing infections in humans. A 4-year-old female Shih Tzu dog was brought to the veterinary clinic with a history of circular, crusted and non-pruritic alopecia lesions located on the head. Routine blood tests, skin scrapes and bacteriological culture revealed no abnormalities. However, Trichophyton rubrum was isolated from the fungus culture. The intradomicilar condition of the dog allows contact with its frequent hosts, the man. The fungicidal treatment was implemented with shampoo (ketoconazole base 2% + chlorhexidine 2%) and oral Itraconazole at a dose of 10 mg / kg once a day, for 28 days. The lesions healed completely and the hair grew back within a month. No recurrence occurred during the 4-month follow-up. T. rubrum should be included in the differential diagnosis of crusted skin lesions in dogs. [ABSTRACT FROM AUTHOR]

Background: Dermatopathy develops as a side effect in patients receiving anti-epidermal growth factor receptor antibody treatment. Topical moisturizers are used for the prevention and treatment of this dermatopathy. Active participation of patients in their own treatment is important for the appropriate application of topical preparations. We prepared a pharmaceutical instructional video for adhering to the topical application protocol. In this study, we investigated the effectiveness of this pharmaceutical instructional video on treatment adherence. Methods: Study participants were patients with cancer receiving the anti-epidermal growth factor receptor antibody for the first time. A pharmacist instructed the patients on how to use the pharmaceutical instruction video. Daily topical preparation use following the video demonstration was assessed. The effectiveness of the pharmaceutical instruction video was evaluated by assessing the adherence of patients who did not use the pharmaceutical instruction video for the past 2 periods (26 months; controls 1 and 2). The incidence of side effects was compared between the two control groups and the group of patients who received the pharmaceutical instruction video. Results: The amount of topical preparation consumed (median, g/day) by patients who received patient compliance instructions using the pharmaceutical instruction video was 9.8 g/day, as compared with control group 1 (4.5 g/day) and control group 2 (5.5 g/day) (p < 0.001). There was no difference in the incidence of side effects during the three periods. Conclusion: The use of visual instructional media for patient compliance by pharmacists may be effective in maintaining and improving treatment adherence. [ABSTRACT FROM AUTHOR]

Dermatopathies and otopathies are recurrent cases in veterinary clinic caused by different microorganisms. The aim of the present study is to analyze reports of cytological and parasitological skin and ear examinations performed at the Clinical Laboratory of the Veterinary Teaching Clinic of Federal University of Juiz de Fora in order to determine the prevalence of bacteria, fungi and mites in the collected samples. Reports of tests carried out from January 2018 to December 2019 were analyzed. Dog otopathies comprised 42 (50%) cases caused by Malassezia sp., 11 (13.1%) cases caused by bacteria and 29 (34.5%) cases caused by mixed infections; whereas cats otopathies encompassed 7 (28%) infections caused by Malassezia sp., 3 (12%) infections caused by bacteria, 6 (24%) mixed infections and 3 (12%) infections caused by mite species Otodectes cynotis. Dog dermatopathies comprised 1 (2.6%) case caused by Malassezia sp., 17 (43.6%) cases caused by bacteria, 7 (17.9%) mixed infections and 3 (7.7%) infections caused by mite species Demodex canis; whereas cat dermatopathies comprised 2 (15.4%) changes caused by bacteria, 3 (23.1%) mixed infections, 2 (15.4%) infections caused by Sporothrix sp., 1 (7.6%) caused by dermatophyte and 3 (23.1%) by yeast. Results have shown that Malassezia sp. was the most prevalent etiological agent in ear diseases diagnosed in both dogs and cats. On the other hand, bacteria were the most prevalent agents in dog skin disorders, whereas mixed infections and fungal agents recorded similar prevalence in cats. [ABSTRACT FROM AUTHOR]

A previously undescribed skin abnormality, referred to as "linear skin markings" (LSM), has been identified in free‐ranging common bottlenose dolphins (Tursiops truncatus) in the Indian River Lagoon, Florida (IRL). The lesions were identified during photo‐identification surveys conducted from 2002 and 2015. LSM presented as distinct, parallel lines running dorso‐ventrally on the torso and varied in length and width. The goals of this study were to determine (1) prevalence of the condition in IRL dolphins, (2) age and sex distribution of affected animals, (3) spatial and temporal distribution patterns, (4) duration of the condition, and (5) development of hypotheses regarding the etiology of the condition. Among 1,357 individual dolphins identified during the study period, 96 (7.0%) showed evidence of LSM. Nearly all (98.8%) cases with an established home range occurred in the northern and central regions of the IRL. The majority of cases of known sex were female (85%), of which 100% had given birth to one or more calves. The mean age of animals with LSM when first observed was 7.3 with a range of 1–20 years. The maximum observed duration of LSM was 15 years. Once observed, the condition persisted indefinitely. The etiology of LSM has not been established. [ABSTRACT FROM AUTHOR]

Eskandar T, Chaudhary F, and Agrawal DK
- Abstract
Orthopedic diseases often present with dermatological symptoms that require prompt identification for appropriate treatment. Understanding these dermatologic presentations is crucial for accurate diagnosis and effective management. This article critically reviewed the dermatological manifestations observed in general and regional pathologies, followed by treatment-related manifestations. An extensive literature search was performed and limited to manifestations in orthopedic disease, excluding those pertaining to infection or syndromes. Case reports and case series documenting unusual and rare dermatologic presentations of orthopedic conditions were examined, providing novel perspectives on both prevalent and uncommon illnesses. The identified pathologies are discussed in detail, including their clinical features and diagnosis, while treatment approach varies depending on the severity of the condition, ranging from self-care to surgical intervention. The findings emphasize the need for interdisciplinary collaboration and highlight the importance of careful diagnosis and appropriate management to eliminate unnecessary approaches and ensure optimal outcomes for patients with orthopedic diseases and dermatologic symptoms., Competing Interests: Competing interests: All authors have read the manuscript and declare no conflict of interest. No writing assistance was utilized in the production of this manuscript.

Background: Dermatomyositis is an idiopathic, inflammatory/immunemediated disease of the skin, muscles and blood vessels of hereditary nature and unclear pathogenesis. This familial disease has been described in certain breeds, especially collies and Shetland sheep dogs and is of rare occurrence in mongrel dogs. To describe and discuss three clinical cases of dermatomyositis-like disease and provide a brief review of the literature. Cases: Three young mongrel dogs are included in this report. Case 1: Mandarino, a 4-year-old mongrel dog, having a history of skin lesions for at least a year. Showed an underweight patient, skin ulcers, crusts, alopecia, peri-ocular scarring causing severe lagophthalmia and a corneal ulcer. Muscle atrophy was most notable in the head and legs; the dog had difficulty and pain walking. Treatment was initialised with cephalexin 30 mg/kg BID, pentoxifylline 25 mg/kg BID, and prednisone 2.2 mg/kg SID. The patient was presented after two weeks for follow up; the anaemia and skin condition had improved, the weight had increased by 2 kg, dysphagia and locomotor abnormalities were not present. Case 2: Milagros, a mongrel female dog approximately two years of age, rescued from a shelter. Physical examination showed facial alopecia, erythema and scarring of the periocular skin, crusting and scaling in alopecic areas, pinnae tip necrosis and crusting, ear alopecia, tail tip necrosis and crusting. Also present were distal limb alopecia, crusting and ulcers in areas of trauma in the hock and carpal surfaces; some nails presented onychorhexis and onychoschizia. The patient has been treated for 12 months with a good clinical outcome, with pentoxifylline, azathioprine 2.2 mg/kg EOD alternating with prednisone 1 mg/kg EOD. Case 3: Chuchito, an 11-month-old male mongrel rescued dog had been previously hospitalised due to his skin condition. Physical examination showed depigmented and alopecic areas in the nasal planum, perioral and periocular areas, and inflammation of the palpebral tissues. Necrosis of the distal pinnae, alopecia and scales were evident, along with sloughing of scales and ulcers. Skin lesions were also present in the distal limbs, and alopecia, erythema and some crusting and scales in the carpal, tarsal and digital areas. Onychodystrophy was present in several digits. This study describes the physical examination and the clinical pathological findings, including skin scrapings, fungal cultures, and skin biopsies, in three dogs with dermatomyositis-like disease, as well as the clinical outcomes after slightly different treatment protocols were used. The biopsy results of two dogs showed ischaemic dermatopathy. Discussion: The most common initial signs of the disease are erythema, desquamation and alopecia in the facial area, ears, distal limbs and pinnae in young puppies aged between two and six months of age, followed by pigmentary changes. Muscular lesions are uncommon; when present, they represent the most severe form of this disease. Dysphagia is a common sign and mega-oesophagus may be present. Patients with muscular disease can manifest difficulty walking, with a stiff high gait. The immune mediated pathogenesis of dermatomyositis can relate to triggering factors in some dogs, such as drugs, infections, paraneoplasms, or toxins. Other potential inducing stressors include oestrus, whelping and excessive solar exposure. Dermatomyositis-like or familiar dermatomyositis is diagnosed using clinical findings, histopathology of skin and muscle, and muscle physiology studies. Electromyography, breed predisposition and genetic background can be helpful in some cases. The clinical findings and response to the treatment of all three cases were compatible with dermatomyositis-like disease in mongrel dogs. [ABSTRACT FROM AUTHOR]

Diabetic neuroosteoarthropathy (Charcot’s osteoarthropathy, DNAP, Charcot’s foot) is a common complication of diabetic neuropathy, which can be easily diagnosed in clinical practice and usually is corrected without leading to severe deformation of the affected joint in case of timely and adequate treatment. We present the result of long-term clinical observation of a patient with early development of complications of type 2 diabetes mellitus, diabetic dermatopathy, common DNOAP with damage to the joints of the feet, ankles, knees and elbows. A feature of the described clinical case is the prevalence of osteoarticular disorders with seizure of atypical diabetes zones – knee and elbow joints, the defeat of which is more characteristic of other diseases (such as collagenoses and syphilis), as well as a combination of DNOAP with diabetic dermatopathy. It seems that the causes of such a common arthropathic process lie in the long course of diabetic neuropathy, which debuted long before the diagnosis of type 2 diabetes, as well as the development and progression of this patient in the last decade of observing diabetic nephropathy and associated secondary hyperparathyroidism. In the modern literature, descriptions of combinations of dermatopathies with other complications of diabetes mellitus are extremely rare, and references to a combination of common DNAP and diabetic bullosis have not been found.

- Abstract
Trichophyton rubrum is rarely isolated from dogs with dermatophytosis. It is an anthropophilic dermatophyte commonly causing infections in humans. A 4-year-old female Shih Tzu dog was brought to the veterinary clinic with a history of circular, crusted and non-pruritic alopecia lesions located on the head. Routine blood tests, skin scrapes and bacteriological culture revealed no abnormalities. However, Trichophyton rubrum was isolated from the fungus culture. The intradomicilar condition of the dog allows contact with its frequent hosts, the man. The fungicidal treatment was implemented with shampoo (ketoconazole base 2% + chlorhexidine 2%) and oral Itraconazole at a dose of 10 mg / kg once a day, for 28 days. The lesions healed completely and the hair grew back within a month. No recurrence occurred during the 4-month follow-up. T. rubrum should be included in the differential diagnosis of crusted skin lesions in dogs., Trichophyton rubrum raramente é isolado de cães com dermatofitose. É um dermatófito antropofílico comumente causador de infecções em humanos. Um cão, fêmea da raça Shih Tzu, de 4 anos de idade foi encaminhado a clínica veterinária com uma história de lesões alopécicas circulares, crostosas e não pruriginosas localizadas na cabeça. Exames de sangue de rotina, raspados na pele e cultura bacteriológica não revelaram nenhuma anormalidade. No entanto, Trichophyton rubrum foi isolado da cultura de fungos. A condição intradomicilar do cão possibilita o contato com os seus hospedeiros frequentes, o homem. O tratamento fungicida foi implementado com shampoo (base de cetoconazol 2% + clorexidina 2%) e Itraconazol oral na dose de 10 mg/kg uma vez ao dia, durante 28 dias. As lesões cicatrizaram completamente e o pelo voltou a crescer dentro de um mês. Nenhuma recorrência ocorreu durante o acompanhamento de 4 meses. T. rubrum deve ser incluído no diagnóstico diferencial de lesões cutâneas crostosas de cães.

- Abstract
Pythiosis is commonly associated with humid and swampy tropical environments. It is considered a pyogranulomatous disease, which in equines mainly affects the skin and subcutaneous tissue. It occurs most frequently in the limbs, face and abdominal region. To the veterinary clinic of the Remington University Corporation is presented an equine of female sex, pinto coat, with an age of eleven years. The patient arrives on the occasion of consultation of a lesion present at the ventral abdominal level, which is granulomatous, ulcerative and apparently necrotic. It presents a lot of purulent discharge active and continuous with several fistulous tracts. To the washing of the wound the presence of structures compatible with Kunkers is evidenced. The diagnostic plan includes blood count and basic blood chemistry. A swab of the wound is sent in order to evaluate the bacterial growth in the culture and the antibiogram. At the therapeutic level, treatment starts with Veterflucina® (composed of penicillin G, streptomycin, flumetasone) and metronidazole locally. Infiltrations are performed in the lesion with Kenacort® (triamcinolone acetate). The response to the treatment established is partially effective, which is why it is decided to perform the surgical removal of the wound by removing a structure with a length of 15 cm long, 7 cm wide and weighing 300 grams. The animal responds satisfactorily to surgery and to date it has not shown recurrence of the pathology., Resumen La pythiosis se relaciona comúnmente con ambientes tropicales húmedos y pantanosos. Esta es considerada una enfermedad piogranulomatosa, la cual afecta principalmente en equinos la piel y el tejido subcutáneo. Además, ocurre con mayor frecuencia en los miembros, el rostro y la región abdominal. Se presenta a la clínica veterinaria de la Corporación Universitaria Remington un equino de sexo hembra, pelaje pinto, con una edad de once años; el motivo de consulta de la paciente es una lesión a nivel ventral abdominal, la cual es de tijo granulomatoso ulcerativo y aparentemente necrótico. El animal presenta secreción mucopurulenta activa y continua con varios tractos fistulosos. Asimismo, al lavado de la herida se evidencia la presencia de estructuras compatibles con kunkers. El plan diagnóstico incluye hemograma y química sanguínea básica. Se envía un hisopado de la herida con el fin de evaluar el crecimiento bacteriano en el cultivo y el antibiograma. A nivel terapéutico, se inicia VeterflucinaR (compuesto a base de penicilina G, estreptomicina, flumetasona) y metronidazol a nivel local. Se realizan infiltraciones en la lesión con KenacortR (acetato de triamcinolona); la respuesta al tratamiento instaurado es parcialmente efectiva, con lo cual se decide hacer la remoción quirúrgica de la herida, retirando una estructura con una longitud de 15 cm de largo, 7 cm de ancho y un peso de 300 gramos. El animal responde satisfactoriamente a la cirugía y a la fecha no ha mostrado reincidencia de la patología.

Dermatophytes are keratinophilic fungi and the causative agent of dermatophytosis in animals and people. In the pathogenesis of this disease, enzymes such as DNase, gelatinase, lipase, keratinase, elastase, and collagenase are highlighted. This work aimed to verify the production of these enzymes by clinical and environmental isolates of dermatophytes. Environmental strains were obtained by the Vanbreuseghem technique (1952), using soil samples from different Brazilian locations. The clinical samples were obtained from animal hair and crust sent to the Veterinary Microbiological Diagnostic Service/UFRRJ. The enzymatic evaluation of the dermatophytes was made by spectrophotometer absorbance readings (collagenase, elastase, and keratinase), degradation halo formation in Petri dishes (DNase and lipase) and tube liquefaction (gelatinase). The clinical isolates were Microsporum canis (11), Nannizzia gypsea (7), N. nana (2), Trichophyton mentagrophytes (4) and Trichophyton sp. (6). The environmental isolates were N. gypsea (25), N. nana (1) and Trichophyton sp. (4). There was no statistically significant difference in keratinase, elastase, lipase and gelatinase production between the clinical and environmental isolates groups. There was a statistically significant difference in collagenase and DNase production. It is concluded that both clinical and soil samples are capable of producing enzymes related to dermatophyte infection. Los dermatofitos son hongos queratinofílicos relacionados con las dermatofitosis en animales y personas. En la patogenia de esta enfermedad destacan enzimas como DNasa, gelatinasa, lipasa, queratinasa, elastasa y colagenasa. En este trabajo, el objetivo fue verificar la producción de estas enzimas por aislamientos clínicos y ambientales de dermatofitos. Las cepas ambientales se obtuvieron mediante la técnica de Vanbreuseghem (1952), utilizando muestras de suelo de diferentes lugares de Brasil. Las muestras clínicas proceden de pelos y costras de animales remitidas al Servicio de Diagnóstico Microbiológico Veterinario / UFRRJ. La evaluación enzimática de los dermatofitos se realizó mediante lecturas de absorbancia en un espectrofotómetro (colagenasa, elastasa y queratinasa), formación de un halo de degradación en placa (DNasa y lipasa) y licuefacción en tubos (gelatinasa). Los aislamientos clínicos fueron Microsporum canis (11), Nannizzia gypsea (7), N. nana (2), Trichophyton mentagrophytes (4) y Trichophyton spp. (6). Los aislamientos ambientales fueron N. gypsea (25), N. nana (1) y Trichophyton spp. (4). No hubo diferencias estadísticamente significativas en la producción de queratinasa, elastasa, lipasa y gelatinasa entre los grupos de aislados clínicos y ambientales. Hubo una diferencia estadísticamente significativa en la producción de colagenasa y DNasa. Se concluye que tanto los dermatofitos de muestras clínicas de animales como los del suelo son capaces de producir enzimas relacionadas con la infección por dermatofitos. Os dermatófitos são fungos queratinofílicos relacionados a dermatofitoses em animais e pessoas. Na patogenia desta doença, destacam-se enzimas como DNase, gelatinase, lipase, queratinase, elastase e colagenase. Neste trabalho, objetivou-se verificar a produção destas enzimas por isolados clínicos e ambientais de dermatófitos. As cepas ambientais foram obtidas pela técnica de Vanbreuseghem (1952), utilizando amostras de solo de diferentes localidades do Brasil. As amostras clínicas foram oriundas de pelos e crostas de animais enviadas ao Serviço de Diagnóstico Microbiológico Veterinário/UFRRJ. A avaliação enzimática dos dermatófitos foi feita por leituras de absorbância em espectrofotômetro (colagenase, elastase e queratinase), formação de halo de degradação em placas (DNase e lipase) e liquefação em tubos (gelatinase). Os isolados clínicos foram Microsporum canis (11), Nannizzia gypsea (7), N. nana (2), Trichophyton mentagrophytes (4) e Trichophyton spp. (6). Os isolados ambientais foram N. gypsea (25), N. nana (1) e Trichophyton spp. (4). Não houve diferença estatística significativa na produção de queratinase, elastase, lipase e gelatinase entre os grupos de isolados clínicos e ambientais. Houve diferença significativa estatisticamente na produção de colagenase e DNase. Conclui-se que tanto os dermatófitos oriundos de amostras clínicas de animais, quanto os do solo são capazes de produzir enzimas relacionadas à infecção dermatofítica.

Canine atopic dermatitis (CAD) is a pruritic, chronic inflammatory disease, recurrent and genetically predisposed, which is the second most frequent allergic skin disorder, and ranks second among all the causes of pruritus in dogs worldwide. Given the absence of data on the occurrence of CAD in the northern region of Brazil, the aim of the current study was to conduct a survey to define the prevalence of canine atopic dermatitis attended at the Dermatology Department of the Mário Dias Teixeira Veterinary Hospital of the “Universidade Federal Rural da Amazônia” (HOVET-UFRA). To determine the prevalence of CAD, a retrospective survey was carried out of clinical records and results of dermatological examinations conducted at the Dermatology Department of HOVET-UFRA Belém, Pará from October 2018 to October 2019. During this period, 456 dogs were examined, of which 25.65% (117) were diagnosed with atopic dermatitis. Among the animals diagnosed, 62.4% (73) were females and 51.7% (29) were of the Shih-tzu breed. This level of atopic dermatitis is considered high. There are still no exact data on the incidence and prevalence of this dermatopathy, with described occurrence ranging from 3 to 15% of the canine population, a geographical relationship may be present. Although a sex-related predisposition has not been proven, a higher incidence of atopy in females is described, which indicated this may be the case. The most commonly diagnosed dogs in this study were the Shih-tzu breed. It is suspected that the regional popularity of some breeds, or the different genetic backgrounds in different geographical areas, may affect the predominance of CAD in some breeds. The results of the present study demonstrate the need for more research on the prevalence of canine atopic dermatitis, and better means of characterizing the population of atopic dogs in the region, so that it is possible to obtain a reliable epidemiological profile. RESUMO: A dermatite atópica canina (DAC) é uma doença inflamatória crônica e pruriginosa recorrente e geneticamente predisposta, que se destaca como o segundo transtorno cutâneo alérgico mais frequente e ocupa o segundo lugar entre todas as causas de prurido em cães. Diante da ausência de dados da ocorrência de DAC na região Norte do Brasil, objetivou-se realizar um levantamento de dados para definir a prevalência de dermatite atópica canina atendida no Serviço de Dermatologia do Hospital Veterinário Mário Dias Teixeira da Universidade Federal Rural da Amazônia (HOVET-UFRA). Foi realizado um levantamento retrospectivo através dos registros clínicos e dos resultados de exames dermatológicos com base nos atendimentos dermatológicos no setor de Dermatologia do HOVET-UFRA Belém/Pará, de outubro de 2018 a outubro de 2019 para determinar a prevalência de DAC. Nesse período, foram atendidos 456 cães e destes, 25,65% (117) foram diagnosticados com dermatite atópica. Dentre os animais diagnosticados, 62,4% (73) eram fêmeas e 51,7% (29) eram da raça Shih-tzu. Neste estudo houve uma alta prevalência de cães com Dermatite atópica. Ainda não existem dados exatos sobre a incidência e a prevalência desta dermatopatia, com ocorrência descrita variando de 3 a 15% da população canina, podendo ter relação geográfica. Embora a predisposição sexual não tenha sido comprovada, descreve-se maior incidência de atopia em fêmeas, concordando com esta pesquisa. Os cães mais acometidos neste estudo foram da raça Shih-tzu. Suspeita-se que a popularidade regional de algumas raças ou os diferentes antecedentes genéticos em diferentes áreas geográficas afetam a predominância de algumas raças. Estes resultados mostraram que a prevalência de DAC em cães é a mais frequentemente diagnosticada no setor de Dermatologia do HOVET-UFRA, sendo mais prevalente em fêmeas e na raça Shih-tzu, podendo refletir um aspecto regional desta dermatopatia. Os resultados do presente estudo contribuíram para demonstrar a importância de mais pesquisas sobre a prevalência da Dermatite atópica canina e melhor caracterizar a população de cães atópicos na região, para que seja possível obter um perfil epidemiológico confiável.

This study has the objective of describing the epidemiology of dermatophilosis in cattle, horse, and sheep in the southern of Rio Grande do Sul during a period of 10 years. Data was gathered of all cases/outbreaks of dermatophilosis in ruminants and equines There were 44 (49,4%) diagnoses of dermatophilosis out of 89 cases presenting non-proliferative cutaneous lesions. Of these, 13 were in cattle, 29 in horses, and two were in sheep. It was made a consultation to the Hospital de Clínicas of Porto Alegre/RS and DATASUS database to determine the occurrence of dermatophilosis in humans due to its zoonotic characteristic. It was observed that both in public hospitals and in the SUS database, dermatopathies are recorded in a non-specific way, and with dermatophilosis being a dermatopathy with nonspecific lesions, the definitive diagnosis with the characterization of the agent is not made. The results of this study allowed to conclude that dermatophilosis has a relative importance in domestic species since mortality not occurs in cattle and horses. Still, one must consider the lower dairy production in cattle. In sheep, there was mortality and losses due to the fall in wool quality, and the disease should be considered in diagnosing skin lesions in this species. In humans, the disease is underreported and the possibility of its occurrence in rural areas is alerted; however, cases rarely reach the laboratory. Este estudio tuvo como objetivo describir la epidemiología de la dermatofilosis en bovinos, equinos y ovinos en la región sur de Rio Grande do Sul, durante un período de 10 años. Para ello se investigó en los protocolos de necropsia/biopsia del laboratorio, identificando los casos de dermatofilosis diagnosticados en estas especies. Se realizaron 44 diagnósticos (49,4%) de un total de 89 casos de lesiones cutáneas no proliferativas recibidas. De estos, 13 fueron en bovinos, 29 en equinos y dos en ovinos. También se realizó una consulta en el Hospital de Clínicas de Porto Alegre/RS y también en DATASUS sobre la ocurrencia de dermatofilosis en humanos para determinar la frecuencia de diagnóstico de esta enfermedad por ser una zoonosis. Se observó que tanto en los hospitales públicos como en la base de datos del SUS, las dermatopatías son registradas de forma inespecífica, y siendo la dermatofilosis una dermatopatía con lesiones inespecíficas, generalmente no se realiza el diagnóstico definitivo con la caracterización del agente. Los resultados de este estudio permitieron concluir que la dermatofilosis tiene una importancia relativa en las especies de producción doméstica ya que la mortalidad en bovinos y equinos es nula. Aún así, hay que considerar la menor producción lechera en el ganado bovino. En ovinos hubo mortalidad y pérdidas por la caída en la calidad de la lana, lo que debe ser considerado en el diagnóstico de lesiones cutáneas en esta especie. En humanos, el subregistro de la enfermedad advierte sobre la posibilidad de su ocurrencia en áreas rurales; sin embargo, los casos rara vez llegan al laboratorio. Este trabalho teve como objetivo descrever a epidemiologia da dermatofilose em bovinos equinos e ovinos na região sul do Rio Grande do Sul, em um período de 10 anos. Para isso realizou-se uma pesquisa nos protocolos de necropsia/biopsia do laboratório identificando-se os casos de dermatofilose diagnosticados nestas espécies. Foram feitos 44 diagnósticos (49,4%) de um total de 89 casos de lesões cutâneas não proliferativas recebidas. Destes, 13 foram em bovinos, 29 foram em equinos e dois foram em ovinos. Foi realizada, também, uma consulta no Hospital de Clínicas de Porto Alegre/RS e, também, no DATASUS sobre a ocorrência de dermatofilose no homem para determinar a frequência do diagnóstico desta enfermidade por tratar-se de uma zoonose. Foi observado que tanto em Hospitais públicos como no Banco de dados do SUS as dermatopatias são registradas de forma inespecífica, sendo a dermatofilose uma dermatopatia com lesões inespecíficas o diagnóstico definitivo com caracterização do agente, de modo geral, não é feito. Os resultados deste trabalho permitiram concluir que a dermatofilose tem importância relativa nas espécies domésticas de produção, uma vez que a mortalidade em bovinos e equinos é nula, porém deve-se levar em conta a queda na produção leiteira em bovinos. Em ovinos houve mortalidade e prejuízos pela queda na qualidade da lã, devendo ser considerada no diagnóstico de lesões de pele nesta espécie. No homem o fato de a doença ser subnotificada, alerta para a possibilidade de sua ocorrência no meio rural, entretanto dificilmente os casos chegam ao conhecimento no laboratório.

CATTLE diseases ,VITAMIN A deficiency ,ORTHOKERATOLOGY ,VETERINARY medicine ,CYTOPLASMIC filaments - Abstract
In juvenile cattle, vitamin A deficiency is reported most commonly as a neurological condition; only rarely are there dermatologic manifestations. In the current study, alopecia, severe epidermal and follicular orthokeratosis, and acanthosis due to hypovitaminosis A are reported in 2 of 32 Angus calves, with a third animal suspected. Affected animals responded to vitamin A supplementation, and no additional calves displayed signs. Vitamin A acts on skin by regulating DNA transcription in keratinocytes, reducing the number of tonofilaments and desmosomes, both involved in cell-to-cell adhesion. Hence, adequate levels of dietary vitamin A are necessary for normal keratinocyte turnover, and deficiencies result in retention of keratinized cells (orthokeratosis). The present report reminds diagnosticians to consider vitamin A deficiency in cases of orthokeratotic dermatopathy in cattle. [ABSTRACT FROM PUBLISHER]

The successful analysis of weak biological stains by means of highly sensitive short tandem repeat (STR) amplification has been increased significantly over the recent years. Nevertheless, the percentage of reliably analysable samples varies considerably between different crime scene investigations even if the nature of the stains appears to be the same. It has been proposed that the amount and quality of DNA left at a crime scene may be due to individual skin conditions (among other factors). Therefore, we investigated DNA from handprints from 30 patients acutely suffering from skin diseases like atopic dermatitis, psoriasis or skin ulcer before and after therapy by STR amplification using the new and highly sensitive Powerplex® ESX17 kit in comparison to 22 healthy controls. Handprints from atopic dermatitis patients showed a correct and reliable DNA profile in 90% and 40% of patients before and after therapy, respectively. Regarding psoriasis patients, we detected full DNA profiles in only 64% and 55% of handprints before and after therapy. In contrast, in ulcus patients and controls, full DNA profiles were obtained in much lower numbers. We conclude that active skin diseases like atopic dermatitis or psoriasis have a considerable impact on the amplificable DNA left by skin contact with surfaces. Since up to 7% of adults in European countries suffer from one of these diseases, this could explain at least partially the varying quality of DNA from weak stains. [ABSTRACT FROM AUTHOR]

Background: The use of antibiotics, especially beta-lactams and macrolides, may be associated with dermatopathies, such as Acute Generalized Exanthematous Pustulosis (AGEP), which is an uncommon cutaneous adverse reaction. Case: We report a case of AGEP, in a 36-year-old multiparous (G5P3C1A1) woman, with 38 weeks of gestation, admitted to the hospital to induce labor. Due to cephalopelvic disproportion, the cesarean section was indicated. In the postoperative period, the patient evolved with cutaneous rash, accompanied by productive cough and dyspnea. Because it was a fever of obscure origin, the treatment with antibiotics, including azithromycin, was initiated. On subsequent days, she presented pustules on the back, abdomen and extremities. Such reaction was attributed to the use of azithromycin. When the drug was discontinued, the lesions regressed significantly. Conclusion: The clinical picture of AGEP may occur with persistent high fever and therefore could be confused with systemic infections, consequently, being treated with wrong medications capable of aggravating the adverse cutaneous reaction, worsening the course of the disease that could be easily treated by stopping the use of the causative drug. This case shows the importance of including AGEP as a differential diagnosis of dermatopathies in the pregnancy-puerperal cycle, especially in women who are using various medications, including antibiotics.

MURRAY cod , *PATHOLOGY , *GOLDFISH , *HYPERPLASIA , *NECROSIS - Abstract
Chronic erosive dermatopathy (CED) is a disease of intensively farmed Murray cod in Australia that has been reported in association with the use of groundwater (mechanically extracted from shallow boreholes) supplies. CED results in focal ulceration of the skin overlying sensory canals of the head and flanks. Trials were conducted at an affected fish farm to study the development of the condition, both in Murray cod and in goldfish, and also to assess the reported recovery of lesions when affected fish were transferred to river water. Grossly, lesions began after 2–3 weeks with degeneration of tissue at the periphery of pores communicating with the sensory canals. Widening of these pores along the axis of the canals resulted from a loss of tissue covering the canal. Histopathologically, hyperplasia of the canal epithelial lining was seen after 3 weeks in borehole water and subsequent necrosis and sloughing of this tissue resulted in the loss of the canal roof. Canal regeneration occurred when fish were transferred from borehole water into river water. The lack of lesions in other organs and the pattern of lesion development support exposure to waterborne factors as the most likely aetiology. [ABSTRACT FROM AUTHOR]

Leishmania infantum is a trypanosomatid that causes parasitic dermatopathy in dogs. Trypanosoma caninum is another trypanosomatid, which infects the skin of dogs, although cutaneous abnormalities are absent. This study aimed to investigate the occurrence of T. caninum infection and its associated cutaneous and histological changes and compare it with the occurrence of L. infantum infection in dogs. The study included 150 dogs, of which T. caninum infection was identified in 3 (2%) and L. infantum infection in 15 (10%) of them, with no association (p>0.05) of these infections with the breed, gender, age, or cutaneous abnormalities. The cutaneous abnormalities were based on 1 (4.8%) and 12 (57.1%) dogs infected by T. caninum and L. infantum, respectively. The dermatohistopathological abnormalities in the dogs infected with T. caninum included mild perivascular lymphohistioplasmacytic infiltrates in the clinically asymptomatic ones, while in those with dermatological abnormalities, acanthosis, epidermal orthokeratotic hyperkeratosis, melanomacrophages, and co-infection with Microsporum sp. and Trichophyton sp. were observed. InL. infantum infected, the histopathological findings included chronic granulomatous inflammatory infiltrates and structures compatible with amastigotes. Despite the low frequency of T. caninum infection, our findings suggest that this trypanosomatid, unlike L. infantum, does not cause any macroscopic skin abnormalities.

Although not obligatory pathogens, Microsporum gypseum, M. canis, and Trichophyton spp. are related to infections in animals, usually associated with circular lesions on the skin. Dermatophytosis by geophilic dermatophytes occurs to a lesser extent, having M. gypseum as the main etiologic agent involved. Among the factors linked to the ability of dermatophytes to infect animals, we highlight enzymes such as DNase, gelatinase, lipase, keratinase, elastase, and collagenase, which were evaluated in the present study. The behavior of domestic animals to be in close contact with the ground, in backyards, public roads, and parks justify the study of geophilic dermatophytes virulence factors and the changes on the enzymatic production between clinical and environmental isolates, which may contribute to control strategies and prevention of dermatophytosis. The main goal of this study was to evaluate the production capacity of enzymes related to the pathogenicity of dermatophytes (DNase, lipase, gelatinase, keratinase, elastase, and collagenase), among environmental and clinical isolates. The environmental strains were obtained by the technique described by Vanbreuseghem (1952), which uses pre-sterilized equines hair mixed with the moist soil, using soil samples from different Brazilian locations. The clinical specimens were obtained from animal hairs and crusts sent to the Veterinary Microbiological Diagnostic Service / UFRRJ and isolated in Mycosel? medium. The enzymatic evaluation of the dermatophytes was performed by spectrophotometry absorbance (collagenase, elastase, and keratinase), enzymatic degradation in Petri dishes (DNase and lipase) and liquefaction in tubes (gelatinase). In a total of 30 clinical isolates, M. canis (11), M. gypseum (7), M. nanum (2), T. mentagrophytes (4) and Trichophyton sp. (6), were identified. Among the 30 environmental isolates are M. gypseum (25), M. nanum (1) and Trichophyton sp. (4). There was no statistically significant difference in the production of keratinase, elastase, lipase, and gelatinase between the clinical and environmental groups, with the synthesis of all the enzymes for most evaluated isolates. There was a statistically significant difference between the groups in the production of collagenase and DNase, with emphasis on the absence of DNase production by most of the environmental isolates. Thus, dermatophytes from clinical and soil samples are able to produce keratinase, elastase, collagenase, DNase, lipase and gelatinase, enzymes related to different stages of the dermatophytic infection in animals and humans. Os dermat?fitos constituem grupo de fungos que requerem queratina para crescimento, colonizando a pele e anexos de animais e pessoas. Embora n?o sejam pat?genos obrigat?rios, Microsporum gypseum, M. canis e Trichophyton spp. relacionam-se a infec??es em animais, causando classicamente les?es circulares na pele. Embora as dermatofitoses por dermat?fitos geof?licos ocorram em menor grau, M. gypseum ? a principal esp?cie envolvida e estes quadros devem ser considerados. Dentre os fatores que fazem com que os dermat?fitos, tenham capacidade de infec??o para animais, destacam-se enzimas como DNase, gelatinase, lipase, queratinase, elastase e colagenase, que foram avaliadas neste trabalho. O h?bito dos animais dom?sticos permanecerem em contato ?ntimo com a terra, em quintais, vias p?blicas e parques, justifica o estudo de sua patogenicidade e a diferencia??o do perfil enzim?tico de isolados cl?nicos e ambientais de dermat?fitos, o que pode colaborar para estrat?gias de controle e preven??o da dermatofitose. Nossa pesquisa teve como objetivos o isolamento cl?nico e ambiental de fungos dermat?fitos, avaliando a produ??o de DNase, lipase, gelatinase, queratinase, elastase e colagenase, enzimas relacionadas ? virul?ncia dos mesmos e a compara??o da capacidade de produ??o dessas enzimas relacionadas ? patogenicidade entre as cepas cl?nicas e ambientais. As cepas ambientais foram obtidas atrav?s da t?cnica descrita por Vanbreuseghem (1952), que emprega pelos est?reis de equinos misturados ao solo umedecido, sendo utilizadas amostras de solo oriundas de diferentes locais do Brasil. As amostras cl?nicas foram oriundas de pelos e crostas de animais enviadas ao Servi?o de Diagn?stico Microbiol?gico Veterin?rio/UFRRJ e semeadas em meio Mycosel?. A avalia??o enzim?tica dos dermat?fitos foi feita por leituras de absorb?ncia em espectrofot?metro (colagenase, elastase e queratinase), forma??o de halo de degrada??o em placas (DNase e lipase) e liquefa??o em tubos (gelatinase). Dentre os 30 isolados cl?nicos est?o M. canis (11), M. gypseum (7), M. nanum (2), T. mentagrophytes (4) e Trichophyton sp. (6). e dentre os 30 isolados ambientais est?o M. gypseum (25), M. nanum (1) e Trichophyton sp. (4). N?o houve diferen?a significativa estatisticamente na produ??o de queratinase, elastase, lipase e gelatinase entre os grupos de isolados cl?nicos e ambientais, sendo a maior parte dos fungos produtora de todas estas enzimas. Houve diferen?a significativa estatisticamente entre os grupos na produ??o de colagenase e DNase, com destaque para a aus?ncia de produ??o de DNase pela maioria dos isolados ambientais. Assim, conclui-se que os dermat?fitos oriundos de amostras cl?nicas e do solo s?o capazes de produzir queratinase, elastase, colagenase, DNase, lipase e gelatinase, enzimas relacionas a diferentes etapas do processo da infec??o dermatof?tica em animais e pessoas.

O plasma rico em plaquetas (PRP) é um produto derivado da centrifugação do sangue total, cuja utilização concentra-se em melhorar a reparação de diferentes tecidos, tendo em vista os fatores de crescimento nele contido. Entretanto, os benefícios da terapia no contexto clínico ainda não estão totalmente esclarecidos. Objetivou-se avaliar a expressão dos genes dos colágenos tipos I e III durante diferentes fases do processo de cicatrização da pele tratada com PRP. Foram utilizados oito equinos machos castrados, mestiços, hígidos, com idade entre 16 e 17 (16,37±0,52) anos. Três feridas em formato quadrangular (6,25cm²) foram confeccionadas nas regiões glúteas direita e esquerda de todos os animais. Doze horas após indução das lesões, 0,5mL do PRP foi administrado em cada uma das quatro extremidades das feridas (T=grupo tratado), de uma das regiões glúteas, escolhida aleatoriamente. A região contralateral foi utilizada como controle (NT=grupo não tratado). As feridas foram submetidas à limpeza diária com água Milli Q, e amostras foram obtidas com biópsias utilizando-se Punch de 6mm de diâmetro. Seis biópsias de pele foram obtidas a primeira no dia de indução das lesões (T0), e as demais com 1 (T1) 2 (T2) 7 (T3) e 14 (T4) dias após a realização das feridas. A sexta biópsia (T5) foi realizada após o completo fechamento da pele. A avaliação da expressão dos genes dos colágenos tipos I e III foi realizada pela técnica qRT-PCR e os dados analisados pelo teste de Bonferroni, t de Student, t pareado e análise de regressão (p

Made available in DSpace on 2021-06-25T10:10:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01 Background: Dermatosparaxis is an autosomal recessive genetic disease that affects the connective tissue of animals. Collagen proteins form fibrillar structures that provide strength and structure to the extracellular matrix of tissues and organs in the body. Therefore, changes in collagen synthesis result in hyperextensibility and skin fragility. Similar to dermatosparaxis in animals, some cases of Ehlers-Danlos syndrome type VIIC have been reported in humans. The objective of this study was to describe the clinical, anatomopathological, and molecular findings of a case of dermatosparaxis in a sheep bred by crossing the Santa Inês and White Dorper breeds. Case: A case of dermatosparaxis was reported in a 20-day-old female sheep, a cross between the Santa Inês and White Dorper breeds. The sheep exhibited hyperextensibility of the skin with minimal tension and increased joint volume shortly after birth. Because of clinical worsening and the poor prognosis of the disease, the owners opted for euthanasia. The necropsy revealed large ulcerated areas in several parts of the body, including the cervical, sternal, scapular, and thoracic regions, and the inner and outer thighs. The skin was extremely easy to be removed during the necropsy and the use of a scalpel was not necessary. Extensive areas of hemorrhage were observed in the subcutaneous tissue and small intestine. The histopathological findings of the skin lesions evidenced the presence of dermatosparaxis, particularly regarding the disorganization of collagen fibers. The tests involving Masson’s trichrome staining, picrosirius red staining, and Gomori’s trichrome staining under polarized light evidence of collagen fiber dysplasia. Discussion: The diagnosis of dermatosparaxis in this study was based on clinical, anatomopathological, and molecular analysis. Molecular diagnosis was confirmed by identification of SNP c.421G>T on the ADAMTS2 gene in both the mother and the sheep under study. In humans, in addition to hyperextensibility and skin fragility, other rare clinical signs include ligamentous laxity, bone abnormalities, vascular abnormalities, uterine rupture, ocular abnormalities, and extensive areas of hemorrhage in the intestine. In this case, the humeral-radial-ulnar joints of both thoracic limbs were substantially enlarged and, when sectioned, a moderate amount of dark yellow fluid was released. Dermatosparaxis is well documented in the White Dorper sheep breed. In the present study, the genetic test revealed that the mother (Santa Inês breed) was heterozygous and phenotypically normal. All the rams in the animal herd (White Dorper breed) were phenotypically normal. Extensive hemorrhage in organs of the abdominal cavity and the high likelihood of skin rupture have been reported in other species that are affected by the disease. The histopathological findings of cutaneous lesions in this sheep agree with the descriptions in the literature on the disorganization of collagen fibers. The tests involving Masson’s trichrome staining, Gomori’s trichrome, and picrosirius red staining under polarized light were crucial for providing evidence of collagen fiber dysplasia. Even when phenotypically normal, the heterozygous sheep in the herd can produce recessive homozygous animals, which may be clinically affected, mainly, if there is a history of uncontrolled crossing in the herd.

Visceral leishmaniasis is an infectious disease of chronic, emerging and zoonotic nature that presents various degrees of severity. In Brazil, this illness is caused by Leishmania infantum (Leishmania chagasi), which is transmitted by the bite of the sand fly Lutzomyia longipalpis, and dogs are its main reservoir. Given the increasing spread of this disease across Brazil, the aim of this study was to report on six cases of canine visceral leishmaniasis, diagnosed in June 2013, in the city of Pedregulho, State of São Paulo, considered to be a non-endemic area and free of phlebotomine sand flies. The diagnosis was based on clinical signs of the patients and additional tests (serological and parasitological). It was concluded that the diagnosis of leishmaniasis is complex because the clinical signs are similar to other systemic diseases, thus justifying the importance of parasitological test of bone marrow, considered "gold standard", in the confirmation of the disease. In addition, the area was not, until now, considered risk place, despite notification. A leishmaniose visceral é uma doença infecciosa de caráter crônico, emergente e zoonótico, apresentando variados graus de severidade. No Brasil, tal enfermidade é causada pela Leishmania infantum (Leishmania chagasi), a qual é transmitida pela picada de flebótomo Lutzomyia longipalpis, tendo o cão como o principal reservatório. Perante a crescente distribuição da doença no território brasileiro, o objetivo do presente trabalho é relatar seis casos de leishmaniose visceral canina, diagnosticados em Junho de 2013, no município de Pedregulho, Estado de São Paulo, considerado área não endêmica e livre de flebotomíneos. O diagnóstico foi baseado nos sinais clínicos dos pacientes e exames complementares (sorológicos e parasitológicos). Concluiu-se que o diagnóstico da leishmaniose é complexo pelo fato dos sinais clínicos serem semelhantes a outras enfermidades sistêmicas, justificando assim a importância do teste parasitológico de medula óssea, considerado “padrão ouro” na confirmação da doença. Além disso, a área não foi, até o presente momento, considerada local de risco, apesar da notificação.

Dentre as especialidades veterinárias, a dermatologia, juntamente com oncologia foram as que se destacaram a partir de 1980. Cerca de 30% dos atendimentos clínicos de carnívoros domésticos são associados com alterações dermatológicas. A maior parte dos dados disponíveis inclui estudos de outros países o que pode não refletir a realidade brasileira. O objetivo deste estudo foi apresentar a prevalência das principais dermatologias neoplásicas e não neoplásicas registradas em gatos, através de diagnósticos histopatológicos de biópsias da pele, realizados no setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (SPV-UFRGS). Um estudo retrospectivo incluiu os resultados de biópsias de pele em gatos registrados entre 1990 e 2012, nos arquivos de diagnósticos histopatológicos do SPV-UFRGS, Porto Alegre, RS, Brasil. De um total de 443 biópsias cutâneas em gatos, 308 casos foram lesões de origem neoplásica que ocorreram em maior prevalência (69%) e afetaram, mais frequentemente, gatos idosos, independente do sexo. Nessa categoria, destacaram-se carcinoma epidermoide 32,14% (99/308), fibrossarcoma 18,83% (58/308), tricoblastoma 12,66% (39/308) e mastocitoma 7,47% (23/308). Entre as lesões de causas não neoplásicas, foram analisadas as de causas micóticas 22,22% (30/135), das quais, a esporotricose apresentou maior ocorrência, com maior prevalência em machos. As lesões de causas alérgicas ocuparam a segunda posição 18,52% (25/135) em prevalência, na categoria não neoplásica. As três dermatopatias mais frequentes foram neoplásicas, micóticas e alérgicas. As neoplasias afetaram mais frequentemente gatos idosos, independentemente do sexo. O carcinoma epidermoide é a dermatopatia neoplásica de maior ocorrência, em gatos sem raça definida, sem predisposição sexual. A esporotricose é a dermatomicose mais frequente e afetou principalmente gatos machos. A escassez de dados registrados nas fichas de solicitação de biópsia reduziu conclusões adicionais. Partindo-se do princípio de que a dermatite solar pode evoluir para o carcinoma epidermoide, e considerando-se o expressivo número de diagnósticos desta alteração entre todas as amostras cutâneas 22,35% (99/443), pode-se reforçar a importância deste estudo ao dermatologista de um país tropical, dando subsídios para a indicação da prevenção à exposição solar, visando prevenir a ocorrência da doença, aumentando o bem-estar dos gatos. Both dermatology and oncology are areas that showed high development since the 1980s. It is estimated that approximately 30% of the clinical services for domestic carnivores have been associated with dermatological alterations. Most of the available data include studies developed outside the country and may not reflect the local situation. This study aimed to presents the prevalence of the main dermatological alterations affecting domestic cats and that were diagnosed by histopathological analysis in the Setor de Patologia Veterinária of Universidade Federal do Rio Grande do Sul (SPV-UFRGS).A retrospective study included the findings observed in feline skin biopsies recorded between 1990 and 2012 in the histopathological files from the SPV-UFRGS. In a total of 443 biopsies, 308 cases showed neoplastic origin which corresponded to most lesions (69%) and affected mostly aged cats, regardless of sex. This category included epidermoid carcinoma 32,14% (99/308), fibrosarcoma 18,83% (58/308), trichoblastoma 12,66% (39/308) and mastocytoma 7,47% (23/308). Epidermoid carcinoma was the top neoplastic dermatopathy and affected mostly undefined breed cats without sexual predisposition. Among the non-neoplastic cases, the mycoses 22,22% (30/135) and the allergic lesions 18,52% (25/135) were the most prevalent. Sporotrichosis was the predominant mycotic alteration and affected especially male cats. Therefore, the three most prevalent categories of dermatopathies affecting cats were neoplasia, mycosis and allergy. Thelack of data recorded in the clinical sheets for biopsy request minimized additional conclusions. Results showed here are highlighted upon consideration that solar dermatitis may evolve to epidermoid carcinoma, which has occurred in a high prevalence in this tropical country, where the prevention to the exposition of these animals to the solar radiation assumes a great role for animal care.

O plasma rico em plaquetas (PRP) é um produto derivado da centrifugação do sangue total, sendo rico em fatores bioativos, como os de crescimento. Apesar da ampla utilização em processos cicatriciais, há controvérsia sobre a eficácia da terapia na cicatrização cutânea. O objetivo desse estudo foi quantificar e comparar a concentração dos fatores TGF-β1 e PDGF-BB no PRP, plasma sanguíneo e pele, durante diferentes fases do processo de cicatrização da pele tratada ou não com PRP. Foram utilizados sete equinos machos castrados, mestiços, hígidos, com idade entre 16 e 17 (16,14±0,63) anos. Três lesões em formato quadrangular (6,25cm2) foram produzidas cirurgicamente nas regiões glúteas direita e esquerda de todos os animais. Doze horas após indução das feridas, 0,5mL do PRP foi administrado em cada uma das quatro extremidades das feridas de uma das regiões glúteas (Grupo tratado = GT), escolhida aleatoriamente. A região contralateral foi utilizada como controle (GC). As feridas foram submetidas à limpeza diária com água Milli Q, e amostras foram obtidas mediante biópsias realizadas com Punch de 6mm. Foram obtidas seis biópsias de pele, sendo a primeira realizada logo após a produção da ferida (T0), e as demais com 1 (T1) 2 (T2) 7 (T3) e 14 (T4) dias após a indução da lesão. A sexta biópsia (T5) foi obtida após completo fechamento da pele, que ocorreu aproximadamente aos 37 dias (36,85±7,45, GC; 38,85±6,46, GT). Também foram obtidas amostras de sangue com EDTA em todos os tempos mencionados. A quantificação dos fatores de crescimento TGF-β1 e PDGF-BB na pele, PRP e plasma sanguíneo foi realizada pela técnica ELISA. Os dados foram analisados estatisticamente pelo teste t, correlação de Pearson e regressão, utilizando nível de significância de 5%. Não houve diferença entre os grupos, nos valores dos dois fatores de crescimento mensurados na pele, nos diferentes tempos. Também não houve correlação entre a quantidade dos fatores de crescimento presentes na pele e no plasma. Por outro lado, correlação positiva foi observada entre PRP e pele no grupo tratado, para os fatores de crescimento TGF-β1 (r=0,31) e PDGF-BB (r=0,38), bem como entre ambos os fatores de crescimento presentes no PRP (r=0,81). Considerando as concentrações dos fatores de crescimento no T0, os maiores valores cutâneos (p

- Abstract
Acanthurus spp. of St. Kitts and other Caribbean islands, including ocean surgeonfish A. bahianus, doctorfish A. chirurgus, and blue tang A. coeruleus, frequently show multifocal cutaneous pigmentation. Initial reports from the Leeward Antilles raised suspicion of a parasitic etiology. The aim of this study was to quantify the prevalence of the disease in St. Kitts' Acanthuridae and describe its pathology and etiology. Visual surveys demonstrated consistently high adjusted mean prevalence at 3 shallow reefs in St. Kitts in 2017 (38.9%, 95% CI: 33.8-43.9) and 2018 (51.5%; 95% CI: 46.2-56.9). There were no differences in prevalence across species or reefs, but juvenile fish were less commonly affected than adults. A total of 29 dermatopathy-affected acanthurids were sampled by spearfishing for comprehensive postmortem examination. Digenean metacercariae were dissected from <1 mm cysts within pigmented lesions. Using partial 28S rDNA sequence data they were classified as Family Heterophyidae, members of which are commonly implicated in black spot disease of other fishes. Morphological features of the parasite were most typical of Scaphanocephalus spp. (Creplin, 1842), and 2 genetic profiles were obtained suggesting more than 1 digenean species. Histologically, pigmented lesions had mild chronic perivascular dermatitis and increased melanophores and melanin density, often centered on encysted digenean metacercariae. In 1 affected A. chirurgus, similar metacercariae were histologically identified in skeletal and cardiac muscle. Further research is needed to clarify impact on host fitness, establish the number of heterophyid digenean species that cause black spots on Caribbean fishes and to determine the intermediate and definitive host species.

Hoof and leg problems are an increasing and very expensive problem especially in the intensive dairy productions all over the world. Not only is the pain caused by bad hoof health a major welfare problem, but several studies have also pointed out the economic importance of hoof problems on farms. From the obvious initial treatment to the secondary expenses of a decreased feed intake due to the animals reduced ability to stand or walk to the feeding stalls, the milk yield and quality is also seriously affected, the effect on the cows reproductive performance, the reduced fertility and increased number of dry days has a massive economic significance on any dairy farm and finally the increased culling rates normally associated to the obvious decreased in performance but are secondary to lameness problems. On this farm containing 352 animals 23.29% of the animals were suffering from a hoof related lameness of which the majority had digital dermatitis, 70% of the infected animals. After an in-depth examination of the herd, it was the environmental conditions that were questioned. The unhygienic farm conditions and the absence of a foot bathing regime were the two highly significant areas of concern with regard to this farms condition.

A number of 266 (6.5%) animals were diagnosed with hypothyroidism. All 100% of the subjects had skin or coat disorders; moreover, 35.7% also had non cutaneous clinical signs of hypothyroidism. The most common dermatopathies were hair coat disorders (65.8%) and keratinization disorders (46.6%). The more repeated non cutaneous clinical signs in the study were metabolic disorders (19.6%) and reproductive (19.2%). The diagnosis of the disease was confirmed dosing the thyroid hormone and TSH (18%), biopsy and histopathology of the skin (35.3%) also by the association of both procedures (46.7%). Within these last group of animals , the histopathology was considered as the most efficient diagnosis method for hypothyroidism (97.6% / 98.2%) as for the Hormone tests the efficiency of this diagnosis was less expressive: T4 Free (72.7% / 75.8%) e T4 Total (77.8% / 73.9%). A percentage of 68,5% of the animals with hypothyroidism , had 1 or 2 secondary diseases or associated to the endocrinopathy, from which immune mediated disorders (45,9%) were accentuated . 157 of the diagnosed patients were submitted to treatment, with positive results in 93.6% of the cases. The disease was most found in females (57,9%). Dogs from 1 to 8 years old (81,6%) represented the age range of the affected animals. There were 43 breeds of dogs involved in the study, from which Chow Chow, Shar pei and English Cocker Spaniel were considered to have predisposition for the disease. Este estudo foi realizado no setor de Dermatologia da Cl?nica Veterin?ria Anim?lia Rio de Janeiro RJ, no per?odo de agosto de 1998 a dezembro de 2005. Do total de c?es atendidos na cl?nica (4107), 19,7% foram encaminhados ao setor, e em 266 destes (6,5%) foi diagnosticado hipotireoidismo. Em todos os c?es foram observadas altera??es na pele, enquanto que, 35,7% tinham tamb?m sintomas cl?nicos n?o cut?neos do hipotireoidismo. As dermatopatias mais comuns foram os dist?rbios de pelagem (65,8%) e os dist?rbios de queratiniza??o (46,6%). Dos sinais cl?nico-gerais n?o cut?neos, destacaram-se dist?rbios metab?licos (19,6%) e reprodutivos (19,2%). O diagn?stico de hipotireoidismo foi realizado atrav?s de dosagens dos horm?nios tireoidianos e TSH (18%), pela bi?psia e histopatologia de pele (35,3%) e pela associa??o entre estes m?todos (46,7%). Neste ?ltimo grupo de animais, a histopatologia foi considerada como o m?todo de diagn?stico mais eficaz para o hipotireoidismo (97,6% / 98,2%). Com rela??o ?s dosagens hormonais, a efic?cia para este diagn?stico foi menos expressiva: T4 Livre (72,7% / 75,8%) e T4 Total (77,8% / 73,9%). Dos animais com hipotireoidismo, 68,5% tinham 1 ou 2 doen?as secund?rias ou associadas ? endocrinopatia, das quais destacam-se os processos imunomediados (45,9%). Dos animais hipotireoideos, 157 foram submetidos ao tratamento, com resposta positiva em 93,6%. As f?meas (57,9%) foram mais acometidas. Animais com idades entre 1 a 8 anos (81,6%) representaram a faixa et?ria mais freq?entemente afetadas. Dentre as 43 ra?as de c?es acometidas, foram consideradas predispostas Chow Chow, Shar pei e Cocker Spaniel Ingl?s.
