Valley fever or coccidioidomycosis is a pulmonary infection caused by species of Coccidioides fungi that are endemic to California and Arizona. Skeletal coccidioidomycosis accounts for about half of disseminated infections, with the vertebral spine being the preferred site of dissemination. Most cases of skeletal coccidioidomycosis progress to bone destruction or spread to adjacent structures such as joints, tendons, and other soft tissues, causing significant pain and restricting mobility. Manifestations of such cases are usually nonspecific, making diagnosis very challenging, especially in non-endemic areas. The lack of basic knowledge and research data on the mechanisms defining susceptibility to extrapulmonary infection, especially when it involves bones and joints, prompted us to survey available clinical and animal data to establish specific research questions that remain to be investigated. In this review, we explore published literature reviews, case reports, and case series on the dissemination of coccidioidomycosis to bones and/or joints. We highlight key differential features with other conditions and opportunities for mechanistic and basic research studies that can help develop novel diagnostic, prognostic, and treatment strategies.

Abstract Background In dogs, the most frequently reported mycosis associated with Aspergillus spp. are respiratory infections. Systemic aspergillosis is uncommon, with reported cases been associated with several Aspergillus species. Aspergillus terreus species complex are ubiquitous organisms, unfrequently associated with local or systemic disease in animals and humans, and treatment of osteomyelitis caused by this species is usually unfavorable. Case presentation This case report describes the case of a 5-year-old dog, referred to the Veterinary Hospital of the Faculty of Veterinary Medicine of the University of Lisbon, Portugal, with a history of lameness of the right thoracic limb. Radiographs and CT scan revealed two different lesions on right humerus and radio, which were biopsied. The samples collected were submitted to cytological and histopathological evaluation and bacterial and mycological culture. Environmental samples, including of the surgery room and of the biopsy needle were also evaluated for the presence of fungi. Regarding biopsy samples, bacterial culture was negative, but mycological analysis originated a pure culture of a fungal species later identified as Aspergillus terreus by Sanger sequencing. Results were compatible with histopathologic examination, which revealed periosteal reaction and invasion of hyphae elements. Also, mycological analysis of both environmental samples evaluated were negative. The virulence profile of the fungal isolate was phenotypically characterized using specific media, allowing to reveal its ability to produce several enzymes involved in its pathogenicity, namely lipase, hemolysin and DNAse, corresponding to a Virulence Index (V. Index.) of 0.43. The patient was submitted to itraconazole therapy for 8 weeks. After 3 weeks, the patient showed significant clinical improvement, and after 6 weeks no radiographic signs were observed. Conclusions Antifungal therapy with itraconazole can contribute to the remission of canine infections promoted by Aspergillus terreus complex with a relevant V. Index.

Fungal osteomyelitis is considered a rare disease, and the published literature mainly comprises case reports, case series and narrative reviews. A systematic review was undertaken to provide a practice-based global perspective on this disease, focusing on epidemiology and treatment strategies. We searched MEDLINE, EMBASE and Cochrane Library between the 3rd and 8th of March 2023 using a predefined search string. We included studies with at least one patient with a diagnosis of fungal osteomyelitis published before the 1st of January 2023. We included all study designs except for reviews, and we excluded non-English languages and grey literature. After exclusion, 678 studies, mostly case reports, were included. Descriptive analysis was performed on 1072 patients. The most common aetiological agent was Aspergillus (26.5%), followed by Candida (20.7%) and Mucor (16.8%), and the bones most frequently involved were the vertebrae. We described the characteristics of patients divided by site of infection, and we found that diabetes mellitus, disseminated fungal infection, surgery and local lesion were major risk factors. We also successfully associated duration of treatment with outcome. We provided a general overview of this rare disease, and we highlighted the need for high-quality investigations on the subject.

Introduction: The second wave of coronavirus disease 2019 (COVID-19) led to the resurgence of opportunistic infections due to the injudicious use of steroids. Sinonasal mucormycosis was declared an epidemic in India during the pandemic. Mucormycosis was managed effectively by surgical debridement along with systemic amphotericin B. Currently, a resurgence of mucormycosis following initial treatment, in the form of fungal osteomyelitis of the frontal bone, is being seen in India. Methods: This prospective study included 10 patients with fungal osteomyelitis of the frontal bone due to mucormycosis. All patients underwent surgical debridement of the sequestrum and involucrum, with systemic antifungal pharmacotherapy. Results: The average duration of time until mucormycosis recurrence was 22 days following initial treatment (range 10–33 days). Patients presented with extracranial bossing following outer frontal cortex erosion (n=3), bicortical erosion (n=3), bifrontal involvement (n=2), dural involvement (n=3), and involvement of the brain parenchyma and prefrontal cortex (n=2). All cases underwent debridement of the entire sequestrous bone and involucrum until normal bone could be identified. The mean admission duration was 4 weeks (range 3–6 weeks). All treated patients are currently alive and without disease, confirmed by contrast-enhanced computed tomography. Conclusion: Based on our experience, the successful treatment of fungal osteomyelitis due to mucormycosis requires a four-pronged approach: early detection, multidisciplinary management of comorbidities, surgical debridement of necrotic bone, and adequate systemic antifungal therapy.

Mucormycosis and Aspergillosis are opportunistic fungal infections causing significant morbidity and mortality. Post the outbreak of COVID-19, these fungal osteomyelitis have seen a global rise with few atypical presentations noted. Current case series reports three such atypical presentations of fungal osteomyelitis including mandibular fungal osteomyelitis in two patients, fungal osteomyelitis mimicking space infection in a middle aged male, and suspected mixed fungal osteomyelitis involving maxillary sinus. Aggressive surgical debridement was indicated along with institution of antifungal therapy (Liposomal Amphotericin B, and Posaconazole). The fungal osteomyelitis was successfully treated with surgical and medical management with no recurrence. The injudicious use of corticosteroids in COVID-19 patients along with their immunocompromised status increases their susceptibility to opportunistic fungal osteomyelitis. Prompt and aggressive surgical intervention along with antifungal therapy is important after diagnosing fungal osteomyelitis, as a delay could increase the mortality rate considerably.

Aims: Our purpose was to describe an unusual series of 21 patients with fungal osteomyelitis after an anterior cruciate ligament reconstruction (ACL-R). Methods: We present a case-series of consecutive patients treated at our institution due to a severe fungal osteomyelitis after an arthroscopic ACL-R from November 2005 to March 2015. Patients were referred to our institution from different areas of our country. We evaluated the amount of bone resection required, type of final reconstructive procedure performed, and Musculoskeletal Tumor Society (MSTS) functional score. Results: A total of 21 consecutive patients were included in the study; 19 were male with median age of 28 years (IQR 25 to 32). All ACL-R were performed with hamstrings autografts with different fixation techniques. An oncological-type debridement was needed to control persistent infection symptoms. There were no recurrences of fungal infection after median of four surgical debridements (IQR 3 to 6). Five patients underwent an extensive curettage due to the presence of large cavitary lesions and were reconstructed with hemicylindrical intercalary allografts (HIAs), preserving the epiphysis. An open surgical debridement was performed resecting the affected epiphysis in 15 patients, with a median bone loss of 11 cm (IQR 11.5 to 15.6). From these 15 cases, eight patients were reconstructed with allograft prosthesis composites (APC); six with tumour-type prosthesis (TTP) and one required a femoral TTP in combination with a tibial APC. One underwent an above-the-knee amputation. The median MSTS functional score was 20 points at a median of seven years (IQR 5 to 9) of follow-up. Conclusion: This study suggests that mucormycosis infection after an ACL-R is a serious complication. Diagnosis is usually delayed until major bone destructive lesions are present. This may originate additional massive reconstructive surgeries with severe functional limitations for the patients. Level of evidence: IV

Background: Coccidioidomycosis represents an endemic and challenging disease, with rare extrapulmonary manifestations. The present review of all published cases of core and extremities osseous coccidioidomycosis aims to describe epidemiology, patients' characteristics, symptoms as well as medical and surgical treatment options and their effectiveness. Methods: A thorough review of all published skeletal core and extremity infections due to Coccidioides species was conducted. Information regarding demographics, causative fungus, antifungal treatment (AFT), surgical management as well as the infection outcome was recorded. Results: A total of 92 cases of Coccidioides spp. skeletal infections were recorded in 87 patients. The patients' mean age was 35.3 years. The most common site of infection was the spine (82.6%), followed by the foot (6.5%), while the predominant symptom upon presentation was pain (29.9%). Immunosuppressive conditions and/or medications were observed in 21 patients (24.1%). Regarding imaging methods, indicating diagnosis, plain X-rays or CT scans were performed in most patients (50.6%), followed by magnetic resonance imaging (MRI) (47.1%). Most cases were diagnosed through histopathology (62; 71.3%), followed by serology testing (36; 42.4%) and by cultures (35; 40.2%). In 32 cases (36.8%), Coccidioides immitis was cultured, while in the remaining 55 cases (63.2%) the fungus was not further characterized. Regarding AFT, amphotericin B was the preferred agent (52.9%), followed by fluconazole (43.3%). In most cases (78.2%) surgical treatment was also performed. Treatment was successful in 80.5% of cases. Conclusions: Skeletal core and extremity infections due to Coccidioides spp. represent a severe disease. With the available data, the combination of prolonged proper AFT with surgical intervention seems to be the optimal current therapeutic approach. [ABSTRACT FROM AUTHOR]

Invasive fungal co-infections with COVID-19 are currently being reported at an alarming rate. Our study explores the importance of early identification of the disease, probable etiopathogenesis, clinical and radiological features and a treatment protocol for COVID-19 Associated Fungal Osteomyelitis of Jaws and Sinuses (CAFOJS). A one-year prospective study from June 2020 to May 2021 was conducted among CAFOJS diagnosed patients at a tertiary care center in South India. Demographic details, COVID-19 infection and treatment history, time taken for initiation of symptoms after COVID-19 diagnosis, medical history and clinical features were recorded. All patients were managed with a standard diagnostic and intervention protocol which included pre-operative and post-operative administration of Inj. Amphotericin B 50 mg (liposomal), early aggressive surgical debridement and tab. Posaconazole GR 300 mg OD for 90 days after discharge. Thirty-nine (78%) patients were diagnosed with CAFOJS out of 50 osteomyelitis patients. 35 patients (90%) were diabetic and 21 patients (54%) were known to receive steroids during the COVID-19 treatment. Sole existence of Mucorales spp. was seen in 30 patients (77%), Aspergillus fumigatus in 2 patients (5%), Curvularia spp. in 2 patients (5%). Concomitant existence of Mucorales and Aspergillus fumigatus was reported in two patients (5%) and Candida albicans in three patients (8%). Patients underwent treatment with standard protocol and no recurrence noted. CAFOJS is a clinical entity with aggressive presentation and warrants early diagnosis and treatment. Lay summary: Invasive fungal infections of head and neck region cause necrosis of bones affected by it, especially maxilla. Early diagnosis and treatment are advocated in such infections due to its aggressive clinical presentation compared to similar infections before COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Background and Importance: Skull Base Osteomyelitis (SBO) is a complex disease process often confused with malignancy due to clinical and radiological masquerade. Extensive changes have recently occurred in the clinical course and management of the disease, attributed to improvements in neurosurgical procedures, diagnostic modalities, and the introduction of new antibiotics and management techniques thus reducing the associated morbidities and mortalities. However, SBO continues to pose a major challenge in the form of early diagnosis and management and can be the cause of devastating complications and high fatality associated with the disease. Case Presentation: Here we provide the clinical profile, investigation, management, and outcome of 5 cases of SBO, all of whom were thoroughly examined for neurological deficit, complete blood count, inflammatory markers, and radiographic imaging. Biopsy and microbiological culture reports were collected and patients were followed up. Conclusion: Early diagnosis and culture-specific antibiotic treatment have been shown to provide good outcomes. Due to its rarity, large case series of SBO are insufficiently found in the literature.

The treatment protocol for COVID-19 along with the presence of important confounders like diabetes and immunocompromised states may predispose individuals to COVID-19-associated mucormycosis. Since mucormycosis is a rapidly progressive and invasive infection with intracranial complications, early diagnosis followed by aggressive medical and surgical interventions is imperative to reduce the morbidity and mortality associated with the disease. The role of dental practitioners in early recognition and referral of the patient is thus paramount. A systematic investigation on the PubMed Database was undertaken and available data were compiled. This paper presents a review of mucormycosis in the current COVID-19 scenario, to act as a ready reference for dental practitioners. [ABSTRACT FROM AUTHOR]

Background: The second wave of COVID-19 pandemic has seen an unprecedented rise in the number of mucormycosis cases worldwide and in India particularly. This otherwise rare fungal infection has become an endemic among patients who have recovered from recent SARS-CoV-2 infection. Among the different types of mucormycosis, rhino-orbital-cerebral involvement has mainly been observed in the recent surge of cases. Very few cases of mucormycosis of mandible have been reported in literature and none in COVID-19 patients. We report a case of isolated mandibular mucormycosis in a COVID- 19 patient, with no other predisposing comorbidities.Case report.A 39 year old patient recently recovered from COVID-19 presented with typical symptoms of osteomyelitis which was confirmed using computed tomography of face. He underwent thorough debridement and curettage and tissue was sent for culture, special staining and biopsy. Result: Diagnosis of mucormycosis was confirmed based on postoperative biopsy and special staining. He was further managed with complete course of appropriate antifungal therapy. Conclusion: Mucormycosis is a fulminant and aggressive infection which requires prompt diagnosis and intervention. Early referral to a maxillofacial surgeon by physicians and general dental practitioners on seeing signs and symptoms of secondary fungal infections involving maxilla or mandible in patients with history of SARS-CoV-19 infection can improve prognosis.

Fungal osteomyelitis is an uncommon complication after cardiac surgery and associated with high mortality. A case of Candida albicans and Staphylococcus epidermidis osteomyelitis with device infection after implantation of a left ventricular assist device in a 60-year-old male patient is presented here. After clinical identification and confirmation with microbiological examinations and fluorodeoxyglucose positron emission tomography (FDG-PET) scan, debridement was performed. Surgical specimens grew C. albicans and S. epidermidis. Fluconazole, daptomycin, and negative pressure wound therapy were initiated, but failed to achieve healing. Total sternectomy and pectoralis flap reconstruction were performed. There was no recurrent infection for C. albicans on a prolonged antifungal regime. The combination of antifungal therapy and aggressive surgical debridement may be useful to control fungal osteomyelitis. [ABSTRACT FROM AUTHOR]

Fungal osteomyelitis is a life-threatening and seldom seen opportunistic infection. It is commonly an affectation of the nose and paranasal sinuses within the orofacial region. It is an aggressive infection that needs to be addressed promptly to prevent fatal consequences. The mode of infection is via the inhalation route and infection begins initially in the nose and paranasal sinuses with subsequent invasion into the vascular tissue, eventually leading to thrombosis and necrosis of nearby hard and soft tissues. Here, we report a case of a 31-year-old male who presented with pain over the upper jaw that was sudden in onset, continuous, dull aching, radiating towards forehead and neck of the left side, aggravates on mastication and relives on its own. He had a history of uncontrolled diabetes mellitus. On further investigation, using diagnostic and Interventional aids, a final diagnosis of mucormycotic osteomyelitis of the maxilla was made.

Fungal osteomyelitis is rarely documented in the maxillofacial region. However, the COVID-19 pandemic has caused a rise in the number of cases with postcovid fungal osteomyelitis of jaws. An invasive lesion can have a devastating effect in the patients. Hence a better understanding of the lesion progression is needed. This case series aims to showcase the progression of such lesions in the maxillofacial region in four COVID-19 recovered patients along with radiographic findings. It is believed that the timely identification and management of these lesions would significantly reducemorbidity and mortality. [ABSTRACT FROM AUTHOR]

The present review of all published cases of core and extremities osseous coccidioidomycosis aims to describe epidemiology, patients’ characteristics, symptoms as well as medical and surgical treatment options and their effectiveness. Methods: A thorough review of all published skeletal core and extremity infections due to Coccidioides species was conducted. Information regarding demographics, causative fungus, antifungal treatment (AFT), surgical management as well as the infection outcome was recorded. Results: A total of 92 cases of Coccidioides spp. skeletal infections were recorded in 87 patients. The patients’ mean age was 35.3 years. The most common site of infection was the spine (82.6%), followed by the foot (6.5%), while the predominant symptom upon presentation was pain (29.9%). Immunosuppressive conditions and/or medications were observed in 21 patients (24.1%).

With the available data, the combination of prolonged proper AFT with surgical intervention seems to be the optimal current therapeutic approach.

Treatment of uncommon fungal infection such as Rhinosporidiosis is challenging, especially when occurring in a non-immunocompromised patient in non-invasive form. Extensive involvement, extending into maxillary jawbone would need aggressive, chemotherapeutic and surgical approach. There are few reports of successful rehabilitation of maxillary jaw with dental implants after treatment of such fungal infection. After adequate medical treatment, the iliac graft and recombinant bone morphogenetic protein-2 was effectively utilized to reconstruct the lost maxillary bone. Later, dental implants were placed, that osseointegrated well.

Introduction: Fungal osteoarticular/soft tissue infections (FOaSI) are an uncommon entity with protracted course due to variability in clinical picture, slow progression; resulting in misdiagnosis with empirical therapy. Recent studies have shown an alarming emergence of FOaSI in immunocompetent individuals with high mortality rates. This study recommends a protocol for managing these complex and confusing scenarios. Methodology: We have retrospectively analysed patients with FOaSI between January 2014 and December 2016, with a minimum 12 months follow up. Results: 8 cases (6 male, 2 female) with a mean age of 42.88 years (26-53) presented to us 45 days (3-365) after initial symptoms. They underwent mean 3 procedures before being diagnosed with a fungal infection. Deep tissue cultures grew 9 fungi and 6 bacteria, commonest fungus being Candida sp (n = 4), treated with appropriate antifungals and antibiotics. Infection remission was achieved in 7/8 (87.5%) cases at 27.1 months (19-45) follow-up with 1 mortality. Excellent functional results as per our criteria were seen in 5 cases (62.5%) with 1 talus excision, 1 ray amputation and 1 mortality. Conclusions: This study highlights the significance of implementing a simple rule such as obtaining fungal cultures in every case of bone and soft tissue infections. Standardisation of treatment may not be the ideal solution, since different fungi have different growth patterns and invasiveness. A simple protocol of customising the medico- surgical treatment with an open ended discussion between the surgeons, microbiologists, pathologists and infectious disease specialists forms the cornerstone to success.

Fungal osteomyelitis is a rare disease which usually presents in an indolent manner. Opportunistic infections due to other non-aspergillus moulds are an emerging entity. We report a case of fungal osteomyelitis due to Acremonium spp in an immunocompetent adult which showed a chronic, indolent course but responded well to treatment with voriconazole. This case highlights the importance of diagnosing the causative agent in fungal osteomyelitis as species specific susceptibility can aid in the treatment of fungal osteomyelitis.

Fungal osteomyelitis is a life-threatening and seldom seen opportunistic infection. It is commonly an affectation of the nose and paranasal sinuses within the orofacial region. It is an aggressive infection that needs to be addressed promptly to prevent fatal consequences. Here, we present a case of a 62-year-old female who presented with complaints of pain and pus discharge from the extraction socket of the left maxillary 23, 24, 25, 26 teeth. She had a history of uncontrolled diabetes mellitus. On further investigation, using diagnostic and Interventional aids, a final diagnosis of maxillary fungal osteomyelitis was made. The infective fungal agents were a mixture of Mucorales and Aspergillus species. A review of all literatures on the subject in the past 13 years using different search engines showed that craniofacial fungal infections with primary maxillary involvement are a rare phenomenon. The primary aim of reporting this case, therefore, is to highlight its rarity, presentation, management and most importantly the outcome of management. [ABSTRACT FROM AUTHOR]

Chromoblastomycosis is a chronic granulomatous infection of the skin and subcutaneous tissue caused by specific group of dematiaceous fungi. The infection results from traumatic injury and is seen more commonly on feet and lower legs. It is rarely seen in children and metastatic spread to other systems is exceptionally rare. We report a 12-year-old immunocompetent male child diagnosed with chromoblastomycosis on the lower leg, who in a span of few months developed osteomyelitis and left hemiparesis. Fungal culture showed growth of Exophiala spinifera. Child showed good improvement with voriconazole and itraconazole after 1 year of treatment. Skin lesions healed with minimal scarring and his power improved.

Skull base osteomyelitis (SBO) is a complex and fatal clinical entity that is often misdiagnosed for malignancy. SBO is commonly a direct complication of otogenic, sinogenic, odontogenic, and rhinogenic infections and can present as central, atypical, or pediatric clival SBO. This review describes the clinical profi le, investigational approach, and management techniques for these variants. A comprehensive literature review was performed in PubMed, MEDLINE, Research Gate, EMBASE, Wiley Online Library, and various Neurosurgical and Neurology journals with the keywords including: SBO, central or atypical SBO, fungal osteomyelitis, malignant otitis externa, temporal bone osteomyelitis, and clival osteomyelitis. Each manuscript's reference list was reviewed for potentially relevant articles. The search yielded a total of 153 articles. It was found that with early and aggressive culture guided long-term intravenous broad-spectrum antibiotic therapy decreases post-infection complications. In cases of widespread soft tissue involvement, an early aggressive surgical removal of infectious sequestra with preferentially Hyperbaric Oxygen (HBO) therapy is associated with better prognosis of disease, less neurologic sequelae and mortality rate. Complete resolution of the SBO cases may take several months. Since early treatment can improve mortality rates, it is paramount that the reporting radiologists and treating clinicians are aware of the cardinal diagnostic signs to improve clinical outcomes of the disease. It will decrease delayed diagnosis and under treatment of the condition. However, due to rarity of the condition, complete prognostic factors have not fully been analyzed and discussed in the literature. [ABSTRACT FROM AUTHOR]

An 18-month-old neutered male labradoodle was treated with surgical debridement for maxillary osteomyelitis and sequestrum formation. Histopathologic findings of the necrotic bone were consistent with Cryptococcus subspecies, confirmed with latex agglutination serum titer testing. The patient responded to a combination of fluconazole and surgical debridement and was titer negative after 8 months of medical therapy. The patient never exhibited signs of systemic illness which is commonly reported with cryptococcosis. Cryptococcus subspecies infection in dogs in the Pacific Northwest is part of an ongoing outbreak in the region, first reported in 2001, and is associated with specific risk factors. This is the first published case of oral cryptococcosis from primary inoculation. [ABSTRACT FROM AUTHOR]

Treatment of uncommon fungal infection such as Rhinosporidiosis is challenging, especially when occurring in a non-immunocompromised patient in non-invasive form. Extensive involvement, extending into maxillary jawbone would need aggressive, chemotherapeutic and surgical approach. There are few reports of successful rehabilitation of maxillary jaw with dental implants after treatment of such fungal infection. After adequate medical treatment, the iliac graft and recombinant bone morphogenetic protein-2 was effectively utilized to reconstruct the lost maxillary bone. Later, dental implants were placed, that osseointegrated well. [ABSTRACT FROM AUTHOR]

Mucormycosis is an opportunistic, uncommon and serious systemic fungal infection mostly presenting in immunocompromised patients. The combination of surgical debridement, parenteral therapy with Amphotericin B and management of the underlying systemic disease is the standard treatment modality for mucormycosis. The drawback of this regime is the need for long hospitalization due to the serious side effects of Amphotericin B requiring regular monitoring. Oral Posaconazole is one of the newer antifungals that have shown promising results. This paper highlights a case series of rhinomaxillary mucormycosis in immunocompetent patients diagnosed and managed successfully with surgical debridement and oral Posaconazole administration on out-patient basis.

Vertebral osteomyelitis also known as discitis/pyogenic spondylitis refers to inflammation of the vertebral disc space. It is commonly seen in men and adults more than 50 years of age. Fungal osteomyelitis is a rare scenario compared to its bacterial counterpart. Spinal epidural abscess is a dangerous complication associated with vertebral osteomyelitis. Here, we report two cases of vertebral osteomyelitis caused by Candida tropicalis in patients with renal disorders (stage 5 chronic kidney disease and nephropathy). One of the case discussed here presented with spinal epidural abscess. Both the patients were started on antifungal therapy. One patient responded to treatment while the other was lost to follow up.

Scedosporium spp. are saprophytic filamentous fungi isolated from soil, sewage and polluted water. Traumatic inoculation is a common way to become infected. We present a case of a patient with septic arthritis and chronic osteomyelitis due to Scedosporium apiospermum successfully treated with voriconazole. [ABSTRACT FROM AUTHOR]

Lasiodiplodia species are environmental fungi that have been reported as a cause of infection in both immunocompetent and immunocompromised patients. We present a case of fungal osteomyelitis caused by Lasiodiplodia species in a patient with multiple myeloma after autologous stem cell transplant. The patient was successfully treated with a combination of surgery and oral voriconzole. To the best of our knowledge, this is the first reported case of fungal osteomyelitis caused by Lasiodiplodia species. [ABSTRACT FROM AUTHOR]

Chromoblastomycosis is a chronic granulomatous infection of the skin and subcutaneous tissue caused by specific group of dematiaceous fungi. The infection results from traumatic injury and is seen more commonly on feet and lower legs. It is rarely seen in children and metastatic spread to other systems is exceptionally rare. We report a 12-year-old immunocompetent male child diagnosed with chromoblastomycosis on the lower leg, who in a span of few months developed osteomyelitis and left hemiparesis. Fungal culture showed growth of Exophiala spinifera. Child showed good improvement with voriconazole and itraconazole after 1 year of treatment. Skin lesions healed with minimal scarring and his power improved. [ABSTRACT FROM AUTHOR]

Study Design. Review of the literature. Objective. To retrospectively examine the frequency of published fungal infections by species and the treatment algorithms used to eradicate the disease. Summary of Background Data. Fungal infections of the spine present unique challenges to the modern multispecialty treatment team. Although rare in comparison with bacterial infections, fungal infections have been increasing in incidence over the past several decades. Evidences-based practice is limited to referencing smaller case series. Methods. MEDLINE, Scopus, and EMBASE searches were carried out by one of the authors as well as by the research desk at the University of Miami/Calder Memorial Library. We included peerreviewed articles published between 1948 and September 2010; case reports, series, and reviews were all examined and compiled into a database. Results. A total of 130 articles, representing 157 cases, were included in the review. Aspergillus (60 cases, 38.2% of the total) and Candida species (36 cases, 22.9% of the total) were the 2 most common organisms. Surgery was associated with a greater survival rate than medical management alone in patients with Aspergillus (26.9% mortality in surgical patients; 60% in medically treated patients) and Candida (0% vs . 28.6%). Overall mortality was 19.3%. The overall recurrence rate was 7.4%. Amphotericin use was associated with a higher mortality rate than azoles. Conclusion. Aspergillus is the most common published pathogen in fungal infections of the spine. Recent publications depicting the use of newer antifungal medications such as azoles report higher survival rates. Surgically treated patients in combination with antifungal therapy showed highest frequencies of patient survival in Aspergillus and Candida infections. [ABSTRACT FROM AUTHOR]
