Background: Hydatid cysts are caused by the larval stage of the tapeworm parasite Echinococcus granulosus, leading to a rare but significant zoonotic infection. This disease is primarily observed in regions with prevalent agricultural and livestock practices. While the liver, lungs, and brain are most affected, spinal involvement is notably rare. Hydatid cyst disease develops gradually and is usually asymptomatic in the early stages. Symptoms usually emerge when the cysts enlarge sufficiently to cause compression. Effective treatment typically combines surgical intervention with antiparasitic medication to reduce the risk of recurrence, highlighting the necessity of a comprehensive approach to treatment and follow-up. Case presentation: A 17-year-old male from Afghanistan, now residing in Iran, presented with muscle weakness in his lower extremities, primarily in the right leg, back pain, and impaired balance. The patient had a history of previous surgical resection for a primary spinal hydatidosis in Afghanistan. Upon examination, he exhibited reduced muscle strength, sensory loss in the right lower limb, paresthesia in the left medial forearm, hyperactive deep tendon reflexes in both legs and a positive Babinski sign on the right. Imaging revealed signs of previous laminectomy at T2 and T3 and a well-defined cystic mass at the T2 level. Surgical intervention was performed to decompress and resect the cyst, and pathological examination confirmed it as a hydatid cyst. Post-surgery, the patient was prescribed chewable albendazole (400 mg twice daily) for six months to prevent recurrence. Routine follow-ups and physiotherapy sessions were recommended after. Conclusion: Patients with spinal hydatidosis often exhibit spinal cord compression symptoms. When imaging modalities reveal multiple cysts and there is a history of residency in an endemic area, spinal hydatid cyst should be considered. Although rare, spinal hydatid cysts are difficult to treat completely. This case highlights the critical need for precise surgical removal, adequate postoperative medication, and long-term follow-up in managing of spinal hydatid cysts. [ABSTRACT FROM AUTHOR]

Due to the side effect of commonly used chemical scolicidals, advantages of micro drug delivery system and growing interest for the phytoceuticals, the present study aimed to find out the scolicidal activity of two volatile terpenes (α-pinene and β-caryophyllene) and their microemulsions on protoscoleces of Echinococcus granulosus. The ordinary and microemulsions of α-pinene and β-caryophyllene and their combination at three different ratios (2:1, 1:1, 1:2) were developed and characterised by dynamic light scattering to confirm micro-dimensions. The scolicidal effect of the developed formulations at the concentrations of 0.5, 1, 2, 5 and 10 μg/mL were measured at 10, 30, and 60-min time points. Mortality rates were recorded by eosin exclusion test. At the 10-min time point, ordinary and micro α-pinene at the concentration of 10 μg/mL killed 94.66% and 100% of the protoscoleces, respectively. At the same time point and concentration, ordinary and micro β-caryophyllene caused 44.33% and 68.66% mortality rates in protoscoleces, respectively. Based on the 50% lethal concentration (LC50) values, there was no significant difference between ordinary and microemulsified α-pinene. For the micro β-caryophyllene, a LC50 value of 2.1 µg/mL was obtained which was significantly lower than that of ordinary β-caryophyllene (49.85 µg/mL). No synergistic interaction existed between β-caryophyllene and α-pinene regarding their activity on E. granulosus. Development of microemulsions increased the toxicity of these terpenoids on protoscoleces, especially that of β-caryophyllene, probably due to improved penetration into the parasite. Further studies are needed to assess in vivo efficacy and safety of this specific preparation. [ABSTRACT FROM AUTHOR]

Background: Hydatid disease, a parasitic infection caused by the larval form of Echinococcus granulosus, infrequently involves the thyroid gland, whether through direct invasion or hematogenous spread. Case presentation: We report the case of a 62-year-old female patient from Morocco who presented with an anterior cervical mass, initially suspected to be a goiter. A histopathological evaluation of the thyroidectomy specimen identified the presence of a hydatid cyst. A comprehensive review of the literature is also included. Conclusion: Given that Morocco is an endemic region for hydatid disease, clinicians should consider this parasitic infection in the differential diagnosis of thyroid cystic lesions, recognizing the clinical and laboratory indicators of the disease.

Background: Hydatid disease is a zoonotic disease caused by the intermediate stage of dog tapeworm Echinococcus granulosus. Objectives: The study investigated the prevalence of hydatid cysts and the risk factors in cattle slaughtered at the Bishoftu municipal abattoir. It also analyzed the economic loss and community's awareness of this matter. Animals: 480 cattle brought for slaughtering were included in the study. Methods: A cross‐sectional study was conducted from December 2022 to April 2023 in Bishoftu municipal abattoir involving antemortem examination of cattle and postmortem hydatid cyst investigation, assessment of associated economic loss, and community awareness survey. Animals were selected systematically and cysts were investigated using standard meat inspection procedures. Results: 10.4% of the slaughtered cattle were found positive for hydatid cysts, with no statistically significant association with the considered risk factors. From 85 collected cysts, the lungs accounted for 55.3%, the liver for 29.4%, and the remaining 15.3% were from the spleen, kidney, and heart. About 47.1% of the cysts were fertile and 52.9% were infertile, of which, 37.5% were nonviable. In a survey of 100 individuals, 33.0% were unaware of hydatid disease, and 61.0% were unaware that the disease is zoonotic. Annual economic loss due to the case was estimated at 5,444,564.4 ($97,224.4). Conclusion: This study identified hydatid disease as a significant issue in cattle in Bishoftu, indicating the need for preventative and control measurements. Strategies such as deworming, controlling street dogs, establishing standardized abattoirs, and raising public awareness should be applied to alleviate the problem in Bishoftu and nationwide.

Introduction: Human alveolar echinococcosis caused by Echinococcus multilocularis is an important zoonotic disease in the northern hemisphere. The life cycle of E. multilocularis is maintained primarily in wild animals and requires an intermediate host (mainly small mammals). Human can become an intermediate host through accidental ingestion of E. multilocularis eggs. Hokkaido Prefecture is the only area of Japan in which human alveolar echinococcosis is endemic. The purposes of this study were to elucidate the land use ecological factors associated with the density of red fox feces along paved roads and the relationship between the distributions of red fox (Vulpes vulpes) populations and fox feces, which determine the level of hazard from eggs. Methods: A series of surveys was conducted in the central part of the Nemuro Peninsula of Hokkaido, excluding urban areas, over a total of 4 years in May–June in 2014 and 2016–2018 when red foxes remain with their cubs around the dens. Transects of 500 m were set up on paved roads, and feces within the transects were counted. Univariable and multivariable analyses were performed to examine ecological factors including the principal components (PCs) of five land use–type occupancy proportions within 500 m and 1 km, respectively, as explanatory fixed-effect variables. The number of feces in each transect was examined as the response variable using integrated nested Laplace approximation with negative binomial errors with a spatio-temporal autocorrelations structure to separate the effects of similarities of neighboring locations and annual variation. The multivariable models with the lowest widely applicable information criterion values were selected. Results: The feces density was explained by the PC of the 500- m buffer (−0.27, 2.5th and 97.5th percentiles: −0.44, −0.10) characterized by mixed forests (−0.82) and scarcity of residential areas (0.29) and the proximity to the nearest livestock farm house (−0.35, 2.5th and 97.5th percentiles: −0.53, −0.17). This suggested that foxes defecate in the areas where prey is abundant, avoiding humans. Discussion: Policy discussions regarding bait distribution design targeting these conditions should be initiated. [ABSTRACT FROM AUTHOR]

Background: Orbital hydatid disease, while rare, should be included in the differential diagnosis of unilateral proptosis, particularly in endemic areas. Accurate diagnosis and comprehensive management are essential for effective treatment and favorable long-term outcomes. Case Presentation: A 12-year-old boy presented with a one-month history of diplopia and left-sided proptosis. A CT scan revealed a cystic mass within the left medial rectus muscle. Surgical intervention confirmed the presence of a hydatid cyst following cyst rupture and irrigation with hypertonic saline. The patient underwent a two-month course of albendazole therapy. Initially, the patient experienced persistent exotropia and diplopia, but at the three-year follow-up, he exhibited no diplopia or proptosis and only mild residual exotropia. Conclusion: This case underscores the importance of considering orbital hydatid cysts in the differential diagnosis of unilateral proptosis in endemic regions. Heightened awareness, accurate diagnosis, and a tailored therapeutic approach, including surgical removal and antiparasitic treatment, are crucial for successful management and improved long-term outcomes.

Rupture of a hydatid cyst can lead to the development of a disseminated form of intra-abdominal cystic echinococcosis if not diagnosed and treated promptly. Anaphylactic shock is a definite indication of cyst rupture. The presented clinical case was a young athlete with a disseminated form of cystic echinococcosis, which was investigated in 2023 at the Syzganov National Scientific Center for Surgery of Kazakhstan. The disease developed gradually following a sports injury to the abdomen during sports training and was accompanied by blurred signs of anaphylactic shock. In the next 2 years, echinococcosis of the abdominal cavity was asymptomatic. The clinical manifestation of cystic echinococcosis developed gradually over the last 10-12 weeks, in the form of dull, painful abdominal pain, malaise, weakness, sweating, nausea, poor appetite, and weight loss. Subacute manifestations of the disease resembled those of acute appendicitis. A diagnostic laparotomy revealed an abundance of cystic formations in the abdominal cavity, necessitating a differential diagnosis between a disseminated form of abdominal tuberculosis with damage to the mesenteric lymph nodes. However, instrumental verification of the parasite, together with the morphological exclusion of the extrapulmonary form of tuberculosis, made it possible to establish a disseminated form of cystic echinococcosis. The patient underwent a cystectomy, was discharged in satisfactory condition, and was informed about the possibility of disease recurrence. In conclusion, in hyperendemic zones, it is recommended to carry out immunological testing for echinococcosis on all abdominal sports injuries, independent of the presence of anaphylactic shock symptoms.

One of the urgent problems of surgical parasitology in the Republic of Kazakhstan is liver cystic echinococcosis. The study aimed to analyze the effectiveness and safety of the percutaneous treatment with different techniques in comparison with the results of laparoscopic and "open" surgical methods. Retrospectively, we analyzed the outcome of 485 patients with active echinococcal cysts in the period from January 2017–July 2023. Indications for surgical treatment and the choice of the intervention method were based on this classification. Patients were conditionally divided into 3 groups: Laparoscopy–33, Laparotomy–319, PAIR-133. The duration of the operation in the PAIR was significantly shorter compared to the Laparotomy and Laparoscopy groups (55.4vs.225.2 and 215.3, p = 0.0001). There was no intraoperative blood loss in PAIR, whereas in Laparotomy and Laparoscopy there were 146.0 and 111.0. The postoperative stay of patients in PAIR is significantly shorter than in Laparotomy and Laparoscopy (3.8 compared to 7.5 and 6.4, p = 0.0001). The follow–up time averaged 39.8 months ± 21. There were no statistically significant differences in relapses. Laparotomy and PAIR groups had 11 (3.5 %) and 6 (4.5 %) relapses, respectively. In cystic echinococcosis of the liver types CE1, CE3a regardless of the localization, the optimal volume is a PAIR is characterized by a shorter postoperative stay of the patient, early recovery and cure. In the CE2, CE3b stages, laparoscopic pericystectomy is the most effective and safe in individual patients. In case of an intimate arrangement of cysts to tubular structures, the safest method is laparotomy. [ABSTRACT FROM AUTHOR]

Hydatidosis (cystic echinococcosis) is one of the major serious parasite infectious diseases that cause poor weight gain and organ condemnation, which contributes to Ethiopia's low cattle industry production. A cross‐sectional study was performed at the Nekemte Municipal Abattoir, Western Ethiopia, from October 2020 to August 2021 with the aim of determining the prevalence of bovine hydatid cysts, assessing the related risk factors, and evaluating the organ level of distributions of the cysts. An antemortem examination and postmortem examination were performed as usual on all 220 chosen slaughtered cattle. We evaluated the organs of systemically selected cattle through visual inspection and palpation. Of the total number inspected, 44 (20%) had one or more hydatid cysts in one or more of their organs. Both age and sex of the cattle were significantly associated with the prevalence of bovine hydatidosis (X2 = 5.928; p = 0.015; and X2 = 4.086; p = 0.043, respectively) among the risk factors evaluated. 44 (20%) of the 220 animals evaluated were positive for hydatidosis. In terms of organ distribution, the liver accounted for 27 (61.4%), the lung for 16 (36.3%), and the spleen for 1 (2.3%). 34 (55.8%) of the 62 cysts counted and characterized were found in the liver, 27 (53.6%) in the lung, and 1 (2.3%) in the spleen. 22 (35.5%) of the 62 cysts collected were calcified, and 31 (50%) were found to be fertile. Of the 31 fertile cysts discovered, 7 (22.6%) were found in the liver, 23 (74.2%) in the lungs, and 1 (2.3%) in the spleen. Hydatidosis is still one of the most critical diseases that need careful consideration for prevention and control measures in the East Welega Zone, even with the moderate level of infection currently detected. This is because there appears to be a socioeconomic environment that is conducive to the disease. Therefore, the installation of regulated, well‐equipped abattoirs, public awareness campaigns, and stray dog control are crucial. [ABSTRACT FROM AUTHOR]

Hydatid cyst contamination in food presents a persistent and pervasive threat to public health. Hence, several studies have been published on hydatid cysts in raw meat products. The current study aimed to meta-analyze the prevalence of hydatid cysts in meat. The search was performed in international databases, including PubMed, Web of Science, Scopus, and Google Scholar, from January 1, 2000, to February 10, 2024. A meta-analysis of prevalence was conducted using the metaprop command in the subgroups of countries, animals, and WHO regions. Meta-regression of the prevalence of hydatid cysts in meat over time and sanitation services ranking was conducted using a random effects model (restricted maximum–-likelihood). Fifty-seven published references with 130 data reports were included in the study. The lowest and highest prevalence of hydatid cysts in raw meat was observed in Sudan at 0.01%, 95%CI (0.01–0.02) and Italy at 69.86%, 95%CI (68.14–71.55), respectively. The highest prevalence of hydatid cysts was observed in Sheep (12.32%), Cattle (11.85%), and Buffalo (10.65%). The lowest and highest prevalence of hydatid cysts was South-East Asian Reg (2.77%) and European Region (33.21%), respectively. Meta-regression showed that the prevalence of hydatid cysts has significantly decreased over time (p-value = 0.021) and insignificantly decreased with sanitation services ranking (p-value = 0.679). Therefore, in order to maintain the existing conditions and even reduce the burden of hydatidosis, public health education, promotion of hygienic practices, and investment need to be carried out continuously.

Introduction: Autism Spectrum Disorder (ASD) is a neurodevelopmental condition marked by difficulties in social interaction, communication, and repetitive behaviors or restricted interests. Although research on the link between ASD and parasitic diseases is limited, immune deficiency and inflammation may contribute to the development of parasitic infections. Case report: We admitted a 14-year-old boy to the hospital who had a known history of ASD because he was presenting with respiratory symptoms, including cough and hemoptysis. During his time in the hospital, after conducting a series of tests and evaluations, we made a critical diagnosis of co-infection of lophomonas, tuberculosis, and hydatid cyst. In response to this diagnosis, we initiated a treatment plan that involved administering appropriate antibiotics as well as preparing for surgical intervention. Conclusion: This case report highlights the complexities and challenges of managing such a rare combination of co-infections with TB, pulmonary hydatid disease and lophomonas in a pediatric patient with underlying developmental considerations such as ASD.

Background: Hydatid disease, also known as echinococcosis, is an endemic parasitic infection, most commonly caused by Echinococcus granulosus. It may affect any organ resulting in the formation of hydatid cysts, but most frequently involves liver and lungs. Hydatid cyst arising primarily from axilla is an extremely rare manifestation of this condition, with only a few cases reported in medical literature. Case presentation: Here we present the case of a 32-year-old Indian male farmer, who presented with a painless, slow-growing mass in the left axillary region of 8 months duration. Preoperative imaging led us to the diagnosis of primary axillary hydatid cyst, with no other associated cysts or masses anywhere else in the body. Following antihelmintic therapy, the cyst was surgically excised without rupture. The diagnosis was further confirmed by macroscopic and histopathological examination. Conclusion: This case report highlights the importance of considering hydatid cyst in the differential diagnosis of palpable masses in the axillary region, especially in regions where the disease is endemic. Early recognition and accurate diagnosis are crucial for appropriate management and optimal patient outcomes. [ABSTRACT FROM AUTHOR]

Hydatid cysts near the porta hepatis present notable medical challenges due to their intricate positioning and potential influence on crucial structures within the liver and its vicinity. While relatively rare, their presence can lead to intricate medical scenarios because of their proximity to vital liver and bile duct structures, but their occurrence can present complex medical situations due to their proximity to critical structures in the liver and bile ducts. We present an unusual case of a 33-year-old male with no known comorbidities presented to the outpatient department of general surgery with pain, insidious in onset and gradually progressive, in the right hypochondrial region for the past 3 months, along with mild fever, reduced appetite, and weight loss of 3 kg. Managing hepatic cysts, especially when near the porta hepatis, poses significant diagnostic challenges. Imaging scans revealed multiple hypodense lesions suggestive of hepatic cysts, with the largest one measuring 5 cm × 8 cm in segment VI. Native post-contrast lesions were also observed in the right lower lobe. Although hepatic duct dilation was not observed, the presence of a cyst near the porta hepatis an atypical site for hydatid cyst, complicated potential PAIR procedures (puncture, aspirate, injection, re-aspirate), raising concerns about the risk of damaging vital structures like the hepatic artery or major bile duct. A multidisciplinary approach engaged interventional radiology to evaluate PAIRS feasibility. PAIRS was performed successfully, except for the cyst near the porta hepatis to avoid complications. Despite this, the patient continued to experience abdominal discomfort post-operation, although liver function tests improved in the postop period. This case underscores the uncommon occurrence of hydatid cysts near the porta hepatis and highlights the need for additional research to comprehend its prevalence and causes. Further investigation is crucial to enhance our understanding of the epidemiology and optimal management strategies involving PAIRS in such challenging cases. [ABSTRACT FROM AUTHOR]

Hydatid cysts, caused by Echinococcus species, are zoonotic diseases frequently observed in endemic regions worldwide, including Turkey. It is most commonly localized in the liver, followed by the lungs. Anaphylaxis and peritonitis, which develop after cyst rupture, are the most significant complications observed in these patients. Early diagnosis and prompt surgical intervention are extremely important. This study presented an extremely rare case of a hepatic hydatid cyst ruptured into the thorax, which may have high morbidity and mortality. A 24-year-old male patient presented to our emergency department with cough, dyspnea, fever, and allergy symptoms. He had a history of hepatic hydatid cyst surgery 5 years ago. Physical examination revealed urticarial lesions on the skin. The body temperature was 39 °C, and the pulse rate was 120 beats/min. Laboratory tests revealed leukocytosis and elevated C-reactive protein. Contrast-enhanced thoracic and abdominal computed tomography was performed. Diagnostic tests revealed that the patient had a ruptured hepatic hydatid cyst in the right thoracic cavity; hence, he was scheduled for emergency surgery. Laparotomy was performed via a right subcostal incision, and the ruptured cyst was located. It was understood that this cyst had fistulized into the diaphragm during a chronic process and subsequently ruptured acutely into the thorax. Partial cystectomy was performed for a ruptured liver cyst. The diaphragm was repaired, and catheters were placed in the thorax and abdomen for drainage. There were no other postoperative complications. Rupture of hydatid cyst disease is frequently observed in endemic regions. The rupture of a hepatic hydatid cyst into the thorax is an extremely rare event. In patients presenting with pulmonary symptoms who have a history of hepatic hydatid cyst surgery, the abdomen should always be thoroughly evaluated, and emergency surgery should be performed if required.

Background: Hydatid disease is a zoonotic infection caused by the species Echinococcus that typically affects the liver. Most liver hydatid cysts are asymptomatic at first, but as the cyst grows larger, symptoms, such as compression effects, start to appear. Ultrasonography and computed tomography scans are the widely used diagnostic tools, and surgery is considered the mainstay of treatment. Case presentation: We present an unusual case of a giant pedunculated hydatid cyst causing inferior vena cava syndrome in a 20-year-old male patient from the Oromo ethnic group from a rural area of the country. Abdominal ultrasound and computed tomography scan confirmed the diagnosis. Our patient underwent radical surgical resection of the cyst and had a good outcome. Conclusion: Hydatid liver cyst diagnosis needs a high index of suspicion for echinococcal etiology when dealing with a giant liver cyst as it results in grave complications without any manifestations.

From a global perspective, hepatocellular carcinoma (HCC) and hydatid cyst disease are both common; however, the endemic and zoonotic nature of hydatid cysts (due to Echinococcus larvae) makes the simultaneous detection of the two conditions a rare occurrence. In this case report, in a 43-year-old male patient, we aim to draw attention to the potential coexistence of HCC and liver hydatid cysts by presenting a case in which HCC tissue was detected in the cyst wall--removed by emergency surgery due to cyst perforation. Hydatid lesions in the liver may exhibit tumor-like growth characteristics. Consequently, identifying a hydatid cyst concomitant with HCC can be challenging, particularly when HCC has developed within the cystic structure. Careful assessment of resected tissues and detailed diagnostic approaches can facilitate the identification of such cases, even if the risk of HCC in patients with hydatid cysts is marginal. It may be advisable to suggest periodic monitoring with HCC-related markers and liver imaging methods. [ABSTRACT FROM AUTHOR]

Echinococcus granulosus remains a global public health issue. Although predominantly affecting the liver, the lungs are the second most affected organ and often undergo surgical intervention. Here, a case managed by bronchoscopy and medical therapy is presented. A 26-year-old woman was presented with a cough, hemoptysis, and a 5 kg weight loss in the last two months. Chest imaging identified a 4 cm centrally cystic mass lesion in the middle lobe of the right lung, which was suspicious of lung cancer. Bronchoscopy revealed a whitish, plasticlike object that was difficult to extricate and obstructed the middle lobe bronchus. We removed the material and purulent secretions covering it and opened the middle lobe bronchus totally. The histopathological study verified its consistency with hydatid cyst. There was no evidence of a hydatid cyst on computerized thomography after bronchoscopy. The lesion in the left lobe of the liver, confirmed to be suggestive of a hydatid cyst via ultrasonography, was treated using the PAIR technique. We administered oral albendazole to continue the treatment. It may be a reasonable approach to postpone surgery in order to preserve lung tissue in patients who have undergone complete removal of hydatid cyst material via bronchoscope. [ABSTRACT FROM AUTHOR]

Background: Intraductal papillary neoplasms of the bile duct (IPNB) are rare precancerous lesions with implications for the development of cholangiocarcinoma (CCA). Recognizing IPNB and managing its recurrence pose challenges in clinical practice. We present two cases. Case 1: a 60-year-old man presented with an 8 × 8 × 9 cm hepatic cyst initially suspected to be a hydatid cyst. Histology post-resection revealed an IPNB with foci of adenocarcinoma. Despite negative oncologic margins, recurrence occurred eight years later as an rT2N0 lesion. Surgical resection was performed without adjuvant chemotherapy, resulting in the patient's survival at 48 months post-surgery. Case 2: a 28-year-old female with cognitive impairment was admitted with pulmonary embolism and a liver lesion diagnosed as a simple cyst. Subsequent evaluation revealed adenocarcinoma with local metastases, extensive vascular involvement, and thrombosis. Despite aggressive management, including thrombectomy and chemotherapy, the patient's condition deteriorated, leading to hepatic failure and eventual demise. Conclusion: IPNB represents a rare premalignant subtype with a propensity for progression to CCA. R0 surgical resection typically offers favorable oncological outcomes with a minimal recurrence risk. Surgical intervention for localized resectable recurrence is both safe and feasible. International registries tracking IPNB recurrence are essential for advancing understanding and optimizing diagnosis, management, and treatment strategies. [ABSTRACT FROM AUTHOR]

Echinococcosis represents a major public health issue and continues to be endemic in various regions around the world. Hydatid cysts are commonly located in the liver (primary site), followed by the lungs (secondary site). However, they are also found in less typical organs such as the spleen, kidneys, peritoneum, retroperitoneum, pancreas, gallbladder, and various other organs, as well as in striate muscles. Hydatid cysts involving the psoas muscle are rare, and in the past five years, only a few articles have addressed this condition due to its low incidence. Symptoms can be quite vague, and serological testing might return negative, making imaging studies crucial for an accurate diagnosis. Treatment options involve surgery alongside antiparasitic agents. Despite having a low mortality rate, the recurrence of hydatid disease remains high. This paper aims to provide new clinical data through our case presentation, while also offering a review of the cases of hydatid cysts involving the psoas muscle that have been published over the past five years.

Introduction: Hydatid disease is uncommon in Humans. It rarely affects the bones and joints (0.5–4%). Frequent sites of bony involvement are vertebrae, pelvic bones, upper end of long bones e.g. humerus, femur and tibia. Material and methods: We report a case of 41-year old female with primary Hydatid cyst of the entire right femur. Patient complaint of severe pain and was non ambulatory since the last 2 months. Results: Here, single staged Total Right Femur Replacement was done under General Anaesthesia. Patient was discharged after 6 days of hospital stay in a stable condition where physical rehabilitation was initiated after day one of the surgery, progressing to aided walking, standing and active lower limb exercises. Conclusion: Involvement of the entire femur was a challenging case. There is no consensus/gold standard treatment of severe cases. Given the involvement of the entire Right Femur along with spillage in the neighbouring muscles, patient underwent Total Femur Replacement with Hip and Knee Replacement. [ABSTRACT FROM AUTHOR]

Background and Objectives: The aim of this study was to evaluate the clinical presentation, treatment outcomes, and complications associated with hepatic hydatid cysts in a pediatric population. Materials and Methods: This retrospective study analyzed 214 pediatric patients with liver hydatid cysts, focusing on clinical presentation, treatment outcomes, and associated complications. Patients were classified based on treatment modality, including non-operative management with albendazole, PAIR, and surgical intervention. This study compared cyst characteristics, recurrence rates, and complications such as cysto-biliary fistulas. Results: Among the patients, 68% (n = 145) had a single cyst and 86% (n = 184) were found to have isolated liver cysts. No significant statistical difference was observed between Group 1 and Group 2 in terms of age, gender, and basic laboratory values and general characteristics of the cysts, such as the lobe where the cyst was located, involvement of multiple organs, number of cysts, the state of cyst rupture, and recurrence; no statistically significant difference was found between the groups (p > 0.05 for each comparison). Cyst rupture incidence was 6%, and the average incidence of recurrence was 2%, with a surgical recurrence incidence of 3%. A total of 37 patients had a laparotomy, while 7 had laparoscopic surgery. In total, capitonnage was performed in 68 patients, omentopexy in 4, and cystostomy in 6. Consequently, among the treated patients (PAIR + surgery), the incidence of cysto-biliary fistula was 11%, anaphylaxis was 2%, surgical recurrence was 3%, and the incidence of reoperation (Clavien–Dindo ≥ 3) was 6%. The average follow-up period was 72 months, during which no mortality was observed. Conclusions: We identified key clinical outcomes related to both non-surgical treatments (cyst rupture and recurrence) and surgical groups (cysto-biliary fistulas, anaphylaxis, the need for reoperation, rupture, and recurrence).

Abstract Background Hydatid cysts are caused by the larval stage of the tapeworm parasite Echinococcus granulosus, leading to a rare but significant zoonotic infection. This disease is primarily observed in regions with prevalent agricultural and livestock practices. While the liver, lungs, and brain are most affected, spinal involvement is notably rare. Hydatid cyst disease develops gradually and is usually asymptomatic in the early stages. Symptoms usually emerge when the cysts enlarge sufficiently to cause compression. Effective treatment typically combines surgical intervention with antiparasitic medication to reduce the risk of recurrence, highlighting the necessity of a comprehensive approach to treatment and follow-up. Case presentation A 17-year-old male from Afghanistan, now residing in Iran, presented with muscle weakness in his lower extremities, primarily in the right leg, back pain, and impaired balance. The patient had a history of previous surgical resection for a primary spinal hydatidosis in Afghanistan. Upon examination, he exhibited reduced muscle strength, sensory loss in the right lower limb, paresthesia in the left medial forearm, hyperactive deep tendon reflexes in both legs and a positive Babinski sign on the right. Imaging revealed signs of previous laminectomy at T2 and T3 and a well-defined cystic mass at the T2 level. Surgical intervention was performed to decompress and resect the cyst, and pathological examination confirmed it as a hydatid cyst. Post-surgery, the patient was prescribed chewable albendazole (400 mg twice daily) for six months to prevent recurrence. Routine follow-ups and physiotherapy sessions were recommended after. Conclusion Patients with spinal hydatidosis often exhibit spinal cord compression symptoms. When imaging modalities reveal multiple cysts and there is a history of residency in an endemic area, spinal hydatid cyst should be considered. Although rare, spinal hydatid cysts are difficult to treat completely. This case highlights the critical need for precise surgical removal, adequate postoperative medication, and long-term follow-up in managing of spinal hydatid cysts.

Due to the side effect of commonly used chemical scolicidals, advantages of micro drug delivery system and growing interest for the phytoceuticals, the present study aimed to find out the scolicidal activity of two volatile terpenes (α-pinene and β-caryophyllene) and their microemulsions on proto-scoleces of Echinococcus granulosus. The ordinary and microemulsions of α-pinene and β-caryophyllene and their combination at three different ratios (2:1, 1:1, 1:2) were developed and cha¬racterised by dynamic light scattering to confirm micro-dimensions. The scolicidal effect of the de-veloped formulations at the concentrations of 0.5, 1, 2, 5 and 10 μg/mL were measured at 10, 30, and 60-min time points. Mortality rates were recorded by eosin exclusion test. At the 10-min time point, ordinary and micro α-pinene at the concentration of 10 μg/mL killed 94.66% and 100% of the proto-scoleces, respectively. At the same time point and concentration, ordinary and micro β-caryophyllene caused 44.33% and 68.66% mortality rates in protoscoleces, respectively. Based on the 50% lethal concentration (LC50) values, there was no significant difference between ordinary and micro-emulsified α-pinene. For the micro β-caryophyllene, a LC50 value of 2.1 µg/mL was obtained which was significantly lower than that of ordinary β-caryophyllene (49.85 µg/mL). No synergistic interac-tion existed between β-caryophyllene and α-pinene regarding their activity on E. granulosus. Development of microemulsions increased the toxicity of these terpenoids on protoscoleces, especially that of β-caryophyllene, probably due to improved penetration into the parasite. Further studies are needed to assess in vivo efficacy and safety of this specific preparation.

Rupture of a hydatid cyst can lead to the development of a disseminated form of intra-abdominal cystic echinococcosis if not diagnosed and treated promptly. Anaphylactic shock is a definite indication of cyst rupture. The presented clinical case was a young athlete with a disseminated form of cystic echinococcosis, which was investigated in 2023 at the Syzganov National Scientific Center for Surgery of Kazakhstan. The disease developed gradually following a sports injury to the abdomen during sports training and was accompanied by blurred signs of anaphylactic shock. In the next 2 years, echinococcosis of the abdominal cavity was asymptomatic. The clinical manifestation of cystic echinococcosis developed gradually over the last 10-12 weeks, in the form of dull, painful abdominal pain, malaise, weakness, sweating, nausea, poor appetite, and weight loss. Subacute manifestations of the disease resembled those of acute appendicitis. A diagnostic laparotomy revealed an abundance of cystic formations in the abdominal cavity, necessitating a differential diagnosis between a disseminated form of abdominal tuberculosis with damage to the mesenteric lymph nodes. However, instrumental verification of the parasite, together with the morphological exclusion of the extrapulmonary form of tuberculosis, made it possible to establish a disseminated form of cystic echinococcosis. The patient underwent a cystectomy, was discharged in satisfactory condition, and was informed about the possibility of disease recurrence. In conclusion, in hyperendemic zones, it is recommended to carry out immunological testing for echinococcosis on all abdominal sports injuries, independent of the presence of anaphylactic shock symptoms.

Abstract Background Hydatid disease, also known as echinococcosis, is an endemic parasitic infection, most commonly caused by Echinococcus granulosus. It may affect any organ resulting in the formation of hydatid cysts, but most frequently involves liver and lungs. Hydatid cyst arising primarily from axilla is an extremely rare manifestation of this condition, with only a few cases reported in medical literature. Case presentation Here we present the case of a 32-year-old Indian male farmer, who presented with a painless, slow-growing mass in the left axillary region of 8 months duration. Preoperative imaging led us to the diagnosis of primary axillary hydatid cyst, with no other associated cysts or masses anywhere else in the body. Following antihelmintic therapy, the cyst was surgically excised without rupture. The diagnosis was further confirmed by macroscopic and histopathological examination. Conclusion This case report highlights the importance of considering hydatid cyst in the differential diagnosis of palpable masses in the axillary region, especially in regions where the disease is endemic. Early recognition and accurate diagnosis are crucial for appropriate management and optimal patient outcomes.

Introduction: Hydatidosis/cystic echinococcosis (CE) is considered a neglected disease due to its preventive nature and impact on low-income populations. In Latin America, there is a high incidence, and in the high Andean regions, it is considered an endemic disease. The objective of this study was to quantify and analyze the scientific production of hydatidosis/echinococcosis through a bibliometric analysis in Latin America up to 2022. Methods: A bibliometric analysis study was conducted based on the scientific production of CE in the SCOPUS database until 2022 in Latin American countries. Information was collected through a systematic search. Frequencies and percentages were used to summarize the variables captured in the final database. Results: Scientific production showed growth over the years, with Argentina, Uruguay, and Chile having the highest production. In addition, there has been a trending use of the term “neglected disease” since 2018. The most cited articles were primarily narrative reviews, book chapters, and original articles in that order. Only 27% of the studies were funded by an institution in Latin America. Conclusion: Scientific production in Latin America regarding CE is on the rise, especially in countries with high incidence rates. Furthermore, these countries demonstrate a significant network of international collaboration.

Abstract Background Zoonotic infections, characterized with huge pathogen diversity, wide affecting area and great society harm, have become a major global public health problem. Early and accurate prediction of their outbreaks is crucial for disease control. The aim of this study was to develop zoonotic diseases risk predictive models based on time-series incidence data and three zoonotic diseases in mainland China were employed as cases. Methods The incidence data for schistosomiasis, echinococcosis, and leptospirosis were downloaded from the Scientific Data Centre of the National Ministry of Health of China, and were processed by interpolation, dynamic curve reconstruction and time series decomposition. Data were decomposed into three distinct components: the trend component, the seasonal component, and the residual component. The trend component was used as input to construct the Long Short-Term Memory (LSTM) prediction model, while the seasonal component was used in the comparison of the periods and amplitudes. Finaly, the accuracy of the hybrid LSTM prediction model was comprehensive evaluated. Results This study employed trend series of incidence numbers and incidence rates of three zoonotic diseases for modeling. The prediction results of the model showed that the predicted incidence number and incidence rate were very close to the real incidence data. Model evaluation revealed that the prediction error of the hybrid LSTM model was smaller than that of the single LSTM. Thus, these results demonstrate that using trending sequences as input sequences for the model leads to better-fitting predictive models. Conclusions Our study successfully developed LSTM hybrid models for disease outbreak risk prediction using three zoonotic diseases as case studies. We demonstrate that the LSTM, when combined with time series decomposition, delivers more accurate results compared to conventional LSTM models using the raw data series. Disease outbreak trends can be predicted more accurately using hybrid models.

Production-limiting diseases, such as helminth infections, are a major concern in temperate regions. They can lead to decreased meat and milk production and quality in livestock. This investigation aimed to assess the prevalence of Fasciola spp., Dicrocoelium spp., and Cystic echinococcosis in different livestock species (cattle, sheep, and goats) at the Khorramabad slaughterhouse between March 21, 2012, and March 20, 2022.ANOVA was employed to assess how disease prevalence varies across different periods and among various livestock species, aiming to comprehend the interplay of these independent variables on disease prevalence. The highest prevalence of Fasciola spp. was related to cattle, with a seasonal pattern showing a higher prevalence in autumn and winter. Hydatid cysts have increased over the past decade, with D. dendriticum being prevalent from 2017 to 2020. The investigation conducted has provided evidence that diseases caused by parasitic infestations in ruminants continue to persist even after treatment. This highlights the need for more effective and targeted sanitary and preventive measures that consider the type of parasite and its prevalence during different seasons. It is hence important to design and implement measures tailored to the specific needs of each parasite species, and aligned with the seasonal fluctuations in its population. This will help minimize the risk of disease transmission, thus reducing the impact on animal health and productivity, ultimately benefitting the livestock industry as a whole.

Abstract Background Echinococcosis, or hydatid disease, is caused by the larval forms of taeniid cestodes belonging to the genus Echinococcus. Echinococcus granulosus and E. multilocularis are the primary species responsible for human echinococcosis, and mostly they affect the liver. The disease course is typically slow, and the patients tend to remain asymptomatic for many years. Case presentation A case of 19-year-old male Somali from Medina, Saudi Arabia, was presented to the Mogadishu Somali Turkey Recep Tayyip Erdogan Training and Research Hospital with the complaint of right upper quadrant abdominal pain and dysuria for 1 month. A thorough physical examination, laboratory examination, and imaging investigations, including abdominal sonography and computed tomography (CT), were conducted. Both ultrasound and CT scans revealed a cystic lesion in the right lobe of the liver, confirming the diagnosis of a hydatid cyst. Consequently, the patient underwent exploratory laparotomy. It was successfully managed surgically, and the definitive diagnosis was provided by the pathologist, confirming degenerated echinococcal cysts that contain abundant debris. Additionally, the patient received oral albendazole both before and after the surgery and after 7 months and is currently symptom-free. Conclusions Hydatid disease in the liver may persist without symptoms and often goes undiagnosed due to the slow growth of the cysts. The diagnosis needs careful history reporting, physical examination, and appropriate imaging investigations.

Abstract Background Cystic echinococcosis, also known as hydatid disease, is a chronic and endemic illness caused by infection with a parasite called Echinococcus granulosus. In Romania, this disease has an incidence rate of 5.6 per 100,000 individuals, which is the highest in the Dobrogea region. The liver is the most affected site, accounting for 68.8% of cases, followed by the lungs at 17.2%. While cases of hydatid disease in the genital organs are rare, occurring at an incidence rate of only 0.5%, it is worth noting that cases of this disease in pregnancy worldwide are also rare, occurring at an incidence rate of 1 in 20,000 to 1 in 30,000 pregnancies. Case report A 15-year-old Eastern-European woman who was 12 weeks pregnant presented to the emergency room with acute pelvic pain, dysuria, and frequent urination. Her laboratory tests showed that she had a urinary tract infection, and pelvic ultrasound revealed that she had a mass on her right adnexa. Despite receiving treatment, her symptoms did not improve, and she had to undergo surgery to remove the mass, which turned out to be a hydatic cyst. She also had to undergo a cesarean section to deliver her baby owing to fetal distress during labor. Conclusions This medical case report provides a detailed description of a pelvic hydatid cyst that was discovered during pregnancy. What makes this case particularly noteworthy is the cyst’s unusual location—it was found at the level of the right broad ligament of the uterus. Despite the complexity of the situation, the patient was able to receive effective treatment and the cyst was successfully managed with great outcomes for both the patient and the newborn. We hope that this report serves as a valuable example of how medical professionals can navigate challenging cases and provide optimal care for their patients.

The splenic localization of hydatid cysts is extremely rare. A 50-year-old obese female who consults with a painful and febrile syndrome of the right hypochondrium. Abdominal ultrasound and a CT scan computed tomography revealed a complete situs inversus, a mass of the right hypochondrium measuring 152 mm with membrane detachment, and infiltration of the surrounding fat, evoking a type II complicated splenic hydatic cyst. The patient was operated on in an emergency via midline laparotomy. Exploration revealed situs inversus, an angiant cyst of the spleen. Exposition of the splenic pedicle is difficult. The samples were then infected. Total splenectomy was performed. The postoperative period was unproblematic, and the patient was discharged with antibiotic and antiparasitic treatment and habitual vaccination.

The co-infection of Pulmonary Tuberculosis (TB) and hydatid disease is rare. Diagnosis and treatment of this co-infection may be challenging as both diseases present with overlapping clinical manifestations, especially in war zones where the health system is destroyed. We are reporting a 45-year-old female police officer transferred to Sinnar Sudan due to ongoing conflict. She was admitted with chronic cough, shortness of breath, and weight loss. The preliminary diagnosis of pulmonary TB was made based on chest X-ray examination and sputum analysis. Further imaging showed cystic lesions in both the liver and the lungs, and thus a diagnosis of Echinococcosis was made. Surgical intervention was done successfully followed by the courses of Albendazole and anti-TB medication. The clinical condition of the patient improved, with the disappearance of all symptoms. This case represents the diagnostic dilemma of dual infections in the areas of their endemicity because of the symptomatology overlap that might occur and result in an erroneous diagnosis. It does demand an appropriate diagnostic approach, thus, with advanced imaging applications, and once more, emphasizes the interdisciplinary attitude in its treatment for the best possible result.

Background: Cystic echinococcosis (CE) is prevalent in livestock farming regions around the world. However, it remains relatively rare compared to other infectious diseases. CE typically affects the liver, lungs, brain, and kidneys. Spinal and pleural wall involvement is exceedingly rare. We report a unique case of intradural and pleural wall CE in a young male, successfully treated with surgery and postoperative medication. Case presentation: A 19-year-old Tibetan male from the Qinghai-Tibet Plateau was diagnosed with intradural and pleural wall CE through imaging, serology, and surgical pathology. According to the Dew/Braithwaite & Lees (BL) classification, his condition was an exceptionally rare form of spinal echinococcosis, compounded by an even rarer pleural wall involvement. Prompt surgical intervention and postoperative medication resulted in significant improvement in spinal cord compression symptoms. Conclusions: This case highlights the diagnostic and therapeutic challenges of rare CE locations. MRI proved superior to CT in diagnosing bony cystic echinococcosis. Early surgical intervention combined with medication facilitates spinal cord function recovery, providing valuable insights for managing similar cases. [ABSTRACT FROM AUTHOR]

Objective: In this study, the impact of inhibiting the PI3K/AKT/NF-κB pathway on lung oxidative damage induced by Echinococcus granulosus cyst fluid was investigated.Methods: Twenty-four mice were randomly assigned to four groups. Three months after inoculation with hydatid cyst segments, mice in group A were treated with intraperitoneal and intratracheal saline injections; mice in group B were administered a caudal vein injection of a PI3K inhibitor, followed by cyst fluid sensitization; mice in group C received an AKT inhibitor via caudal vein, followed by cyst fluid sensitization; and mice in group D were subjected to cyst fluid sensitization without any inhibitor treatment. Cellular changes in lung tissues across all groups were evaluated, including pathological section analysis. Analysis of pulmonary tissue and serum from these mice included the assessment of PI3K/AKT/NF-κB pathway proteins, inflammatory factors, and related mRNA levels.Results: Mice in groups B and C exhibited a higher proportion of M2-type macrophages and significantly lower levels of PI3K/AKT/NF-κB pathway proteins, inflammatory factors (interleukin-6 [IL-6]/tumor necrosis factor-α [TNF-α]), and oxidative markers in lung tissues compared to mice in group D (P < 0.05).Conclusion: Our results in this study indicate that activation of the PI3K/AKT/NF-κB pathway contributed to an increase in the M1 macrophage phenotype, leading to enhanced secretion of peroxidases and inflammatory factors. This mechanism plays a crucial role in the oxidative and inflammatory lung damage associated with allergic reactions to E. granulosus cyst fluid. [ABSTRACT FROM AUTHOR]

Simple hepatic cysts of the liver (SHCL) are incidentally detected in the liver, and may be solitary or multiple. There is sufficient evidence supporting the role of laparoscopic surgery in the treatment of these lesions. The aim of this study was to report the outcomes of laparoscopic treatment in patients with BSHCs in terms of postoperative complications (POC). Case series. All patients who underwent laparoscopic surgery for BSLC at RedSalud Mayor Clinic between January 2013 and December 2023 were included. Preoperative assessment consisted of general examinations, determination of ELISA-IgE and IgG for hydatidosis, abdominal ultrasound or computed tomography. The outcome variable was the development of postoperative complications (POCs). Descriptive statistics were used. During the study period, 22 patients with BSLC were operated, resecting them a total of 34 cysts. The median age of the series was 59 years, and 81.8 % of patients were female. The median sonographic diameter of the lesions was 9 cm. Subtotal pericystectomy was performed in all of them, without using drainage. In 45.4 % of cases simultaneously cholecystectomy for coexistent cholelithiasis was performed. The median operative time was 52 minutes. No patients needed to be converted. The series does not register POC or mortality. The median hospital stay was 1 day. The histopathological study confirmed "biliary type cyst" in all cases. With a minimum follow-up of 6 months, no late postoperative complications or recurrence of the resected lesions have been observed. The treatment applied to this series of cases was associated with a short hospital stay and good short- and medium-term outcomes. [ABSTRACT FROM AUTHOR]

The complete removal of a pulmonary hydatid cyst by bronchoscopy occurs rarely in clinical practice. We describe a 22‐year‐old male originally from Lebanon, with suspected hydatid cyst rupture on computed tomography chest after experiencing sudden onset fevers and cough whilst taking empiric anthelmintic therapy. Bronchoscopy revealed white gelatinous material in the posterior segment of the left lower lobe. The complete membranes of a hydatid cyst were removed with grasping forceps. Histologic examination confirmed the diagnosis of echinococcosis. [ABSTRACT FROM AUTHOR]

Background: Hydatidosis, caused by the larval stage of the tapeworm Echinococcus granulosus, affect cattle by forming hydatid cyst in thier lungs, livers and pose great financial loss in animal production and country's economy by both direct and indirect effect. Despite its great economic and health importance, there is an absence of current information on cystic echinococcosis in cattle slaughtered at Wolaita Sodo municipality abattoir in Ethiopia. Objectives: Current investigation determines the prevalence, organ distribution and fertility of hydatid cysts in cattle slaughtered at the Wolaita Sodo municipality abattoir in Ethiopia. Methods: A cross‐sectional study was conducted from February, 2023, to October, 2023, at Wolaita Sodo municipality abattoir in southern Ethiopia, through regular meat examinations and cyst characterisation to determine the prevalence, organ distribution and fertility of hydatid cysts. Results: The overall prevalence of hydatidosis recorede in current study was 17.9% (69/384) and has shown a statistically significant association (p < 0.05) with the body condition of cattle. However, there was no statistically significant association (p > 0.05) between the prevalence of hydatidosis and other risk factors such as sex, breed, production system and origin of animals. This study showed that the lungs and liver were the most affected organs in cattle, followed by the spleen and kidneys. On cyst characterisation, the majority of hydatid cysts were found sterile (55.4%) followed by fertile (38.8%) and calcified (8.7%) cysts. Out of 125 fertile hydatid cysts tested for survival, 18.8% (58/321) were viable and 20% (67/321) were nonviable. Conclusion: The finding of this study shows that cystic echinococcus was important health threat of the cattle and widespread in the internal organs of affected cattle causing significant economic loss by condemning edible organs that are not suitable for human consumption. Therefore, urgent and integreted preventive action is needed to disrupt the life cycle of cystic echinococcosis to tackle subsequent financial loss and risk of zoonosis to humans in the study area.

Surgery is the main efficacious treatment for many cases of cystic echinococcosis by removing Echinococcus granulosus cysts. However, to reduce risk of cyst spillage and insemination of the content, using a scolicidal agent is crucial. Considering side effects of available scolicidals, and growing nanotechnological approaches in novel pharmaceuticals, the present study aimed to find out the scolicidal activity of geraniol (GL), geranium oil (GM), and their developed nanoemulsions (Nano-GL and Nano-GM) on the protoscoleces of E. granulosus. Nanoemulsions were developed by ultrasonication emulsification and characterised by dynamic light scattering method (DLS). The scolicidal effect of GL, GM, Nano-GL, and Nano-GM at different concentrations of 1, 2.5, 5, 10, 25, and 50 µg/mL were determined after 0.5, 1, and 2 hours of incubation. Mortality rates were measured by eosin exclusion test. The average droplet size for Nano-GM and Nano-GL were 124.8 and 88.59 nm, respectively. After one hour of exposure, all tested concentrations of GL and Nano-GL resulted in higher than 90% mortality rates, while GM and Nano-GM killed 70.66% and 90.33% of protoscoleces, respectively. Based on 50% lethal concentration, Nano-GL was significantly more potent than Nano-GM (LC50: 4.52 vs 102.95 µg/mL). Results of scanning electron microscopy revealed tegumental disruption in the treated protoscoleces. This study described an easily applicable and eco-friendly procedure of nano-formulating functional phytochemicals, showing promising scolicidal activity in vitro. The developed formulations, especially Nano-GL, showed the characteristics of an ideal scolicidal agent. Further studies are needed to assess in vivo efficacy and safety of this formulation.
