UNASSIGNED: Hydatid cyst is a parasitic infection, often caused by Echinococcus granulosus. Although it is classified as a benign disease, cyst ruptures in the abdomen can be fatal. Ruptures occur spontaneously or after trauma. We aimed to report data from patients who underwent emergency surgery due to spontaneous intra-abdominal hydatid cyst rupture.
UNASSIGNED: Upon a retrospective review of the records at Department of General Surgery, Faculty of Medicine, Harran University, Şanlıurfa, Turkey, we found that 34 cases were operated on due to hydatid cyst rupture between January 2012 and October 2022. All patients were operated on in an emergency, and partial cystectomy, intra-abdominal irrigation, and drainage were performed using laparotomy. The patients were evaluated in terms of age, sex, symptoms, radiological findings, laboratory results, intraoperative findings, and postoperative follow-ups.
UNASSIGNED: Twenty-two (64.7%) female and 12 (35.3%) male patients were enrolled. The mean age was 39.1 (±17.58) years. All patients experienced spontaneous rupture. The ruptured cyst was found in the liver in 32 patients (94%), the spleen in 1 patient (3%), and the pelvis in 1 patient (3%). The diagnosis was determined using ultrasonography in 12 (35.3%) patients, computed tomography in 21 (61.8%) patients, and magnetic resonance imaging in 1 (2.9%) patient. All patients exhibited acute abdomen and leukocytosis. The average length of hospital stay was 5.14 (±1.37) days.
UNASSIGNED: Hydatid cyst rupture should be considered in cases of acute abdomen, particularly in regions where the disease is endemic, as in our region. The ruptured hydatid cyst was primarily observed in the liver (94.11% of cases).

OBJECTIVE: Superinfection of cystic echinococcosis (CE) is a life-threatening complication with significant morbidities, which can be prevented with early diagnosis and treatment. This study aims to examine the clinical characteristics, diagnostic methods, and treatment options for superinfected CE, as there is currently limited information available on the differences between superinfected and non-infected CE in terms of clinical features, serological and radiologic findings.
METHODS: This cross-sectional study was conducted on hospital records of patients who were diagnosed with hydatid cysts in a 15-year period (2004 to 2018) in two main university-affiliated referral centers in Fars province, southern Iran. Patients\' information regarding the demographical and clinical features related to CE, age, sex, previous history of CE or recurrence, size and location of CE, and length of hospital stay were collected. Moreover, the characteristics of concurrent infections with hydatid cysts were recorded.
RESULTS: A total of 586 surgeries due to CE were performed on 501 patients, of which 67 (11.43%) had reoperations due to the recurrence of the disease. A total of 30 (5.99%) incidences of superinfection were observed. There were no statistically significant differences in terms of laboratory and imaging findings between CE patients with concurrent infections and other CE patients (p-value > 0.05). Among the patients with super-infection, four had fungal infections of the lungs. Aspergillus fumigatus was the causative pathogen in all four patients that were diagnosed with fungal superinfection. All patients underwent surgical excision with favorable long-term outcomes.
CONCLUSIONS: Our study revealed a 5.99% incident rate of CE superinfection. Regarding the concurrent fungal infections in hydatid cysts, the patient\'s symptoms and laboratory and imaging findings are inconclusive and histopathological evaluation seems to be the most reliable option. Surgical resection is the gold-standard treatment option with favorable outcomes and potentially can be curative.

UNASSIGNED: Involvement of central nervous system (CNS) by Hydatid cyst is rare comprising 0.5-4% of all hydatid cysts and principally affecting those younger than 20 years, giving rise to cystic masses mostly in the cerebral hemispheres. To report the clinicopathological findings of CNS hydatid cysts, we diagnosed and review the findings of the previous studies.
UNASSIGNED: All cases reported in our Section between January 1, 2001, and June 30, 2022, were included in the study. By searching our files, cases were retrieved, and diagnosis was confirmed. Follow-up was received on telephone. Ethical exemption was obtained.
UNASSIGNED: Thirty-three cases were diagnosed. Almost all were received from rural areas. There were 17 females and 16 males. Mean and median age were 20 and 19 years, respectively. Over 60% were younger than 20 years of age. All 33 involved the cerebral and cerebellar hemispheres. Seventy six percent were supratentorial while 24% were infratentorial. The most common signs and symptoms included weakness, headaches, and seizures. All appeared as solitary cystic masses on imaging. Almost 67% were clinically suspected to be hydatid cysts. Grossly, thin-walled transparent unilocular or multilocular cysts filled with viscous material were received intact in 52% and in multiple pieces in 48% cases. Intact cysts measured 7 cm on average. All demonstrated typical histology. Of the nine patients whose follow-up was available, one died from unspecified acute surgery related complications. Four patients were asymptomatic at the time of follow-up, whereas four developed recurrent cysts. All eight received albendazole therapy.
UNASSIGNED: Cerebellum/posterior fossa location was common. Several cases were received in multiple pieces with increased risk of recurrence. Clinicopathological features were similar to those reported in literature. This series will hopefully serve to increase awareness regarding CNS hydatid disease.

BACKGROUND: A mediastinal teratoma is a very rare disease, in which a relatively large mass grows in the space between the two lungs. Although it is a congenital abnormality, it is diagnosed late in the second or third decade. It could be benign or malignant, symptomatic or asymptomatic.
METHODS: A five-year-old child presented with an acute respiratory distress episode due to an acute infection, unresponsive to first-line antibiotics and had a history of similar recurrent pulmonary infections. On imaging, the patient showed an abnormal mediastinal mass which was speculated to be a hydatid cyst or abscess; however, it was later diagnosed during surgery as a mature mediastinal cystic teratoma.
CONCLUSIONS: Mediastinal tumors are slow-growing tumors that are mostly benign and asymptomatic, but sometimes they may grow, reaching a state where they can affect the neighboring anatomical structures, causing symptoms, which may lead to misdiagnosis.
CONCLUSIONS: Teratomas, as a differential diagnosis, should be considered in children with recurrent pulmonary infection and radiological findings that resemble masses in the chest. This emphasizes on the importance of performing detailed radiological and lab investigations to set an appropriate diagnosis to ensure a better treatment and prognosis.

Through this study we aimed to determine the risk factors affecting the transmission of Echinococcus granulosus to humans.
This case-control study included a study group comprising of 107 people who underwent surgery for hydatid cyst and a control group comprising of 107 people. Place of living, age, and sex were taken as matching factors. A chi-square analysis was used for paired comparisons in the study. The variables that were significantly related in paired comparisons were included in the logistic regression analysis.
Hydatid cyst disease was seen 3.661 [confidence interval (CI) =1.650-8.123] times more often in individuals with an education period of 11 years or less compared to those with 12 years or above, 3.427 (CI=1.470-7.991) times more in those with a toilet outside the house compared to those with a toilet inside the house, and 5.540 (CI=2.088-14.697) times more in individuals who took a shower 8 times a month or less compared to those who take a shower 9 times or more.
Individuals with a low level of education and who do not pay attention to environmental and personal hygiene are at risk for hydatid cyst disease.

Clinical presentation of echinococcosis in paediatric population is varied and depends on the site of involvement. The present study was planned to analyse the clinical presentations and therapeutic options for management of echinococcosis in children admitted to a tertiary care hospital. Medical records of children with echinococcosis was reviewed retrospectively over a period of 3 year and 6 months. Demographic data, clinical presentation, management and outcome data were collected and analysed. During the study period, 14 children with hydatid disease were admitted to the hospital. The frequency was higher in male (71.4%) compared to females (28.6%). Liver was found to be the commonest site for hydatid cyst with 78% of all cases had hydatid cyst localised to liver. In half of all cases liver was the only site of involvement. Both liver and lung were involved in 21.4% cases and one patient (7.1%) had pelvic hydatid cyst in addition to liver involvement. Two patients (14.3%) had only pulmonary involvement and one (7.1%) patient had a hydatid cyst in common bile duct. Right upper abdominal pain was the most common presentation (78.5%) with cyst in liver. Cough, breathing difficulty, jaundice was observed in 28.5%, 21.4% and 7.1% of all patients respectively. All children were managed with a combination of surgical and medical therapy. Right upper abdominal pain and chronic cough were the common clinical presentation of hydatid cyst with hepatic and pulmonary involvement respectively. Presence of such chronic symptoms would raise the clinical suspicion of hydatid disease in endemic regions.

Echinococcus granulosus is a major public health problem in lower middle-income countries (LMIC). Children are commonly diagnosed with cysts in the lungs and/or the liver.
The purpose of this study was to describe a pediatric cohort diagnosed with pulmonary Cystic Echinococcus (CE) and treated with a combination of medical and surgical therapy.
This was a retrospective study performed between July 2017 and December 2020 at Tygerberg Hospital, South Africa. Clinical, laboratory, radiological, medical, and surgery-related outcomes were reviewed.
The cohort consisted of 35 children, 17 (49%) were male, with a mean age of 9 ± 5.4 years. The most frequently encountered presenting symptom was cough (93%) followed by fever (70%). Isolated pulmonary CE accounted for the majority of cases (74%) with left lower lobe predominance. A significant proportion of the cohort exhibited chest computed tomography (CT) characteristics consistent with complicated pulmonary CE. Eighteen (58%) children had a positive indirect hemagglutination assay (IHA) test result. All children received medical treatment whilst 30 (86%) of children required surgery. Children with complicated pulmonary CE stayed a mean of 12.5 ± 6.6 days, while those with simple cysts stayed 6.8 ± 1.5 days.
Isolated pulmonary CE is common in children, whereas extrapulmonary cysts are uncommon. Pulmonary CE is diagnosed using chest X-ray and, CT imaging. IHA serology has limited diagnostic utility for pulmonary CE. Combined surgery and chemotherapy remains the gold standard for treating pulmonary CE.

OBJECTIVE: Cystic echinococcosis is a zoonotic disease caused by the cestode Echinococcus granulosus. The activity of the cysts is assessed through the WHO-IWGE standardized classification based on ultrasound features. However, viability of the cysts is not always concordant with the activity assessed by ultrasound. The aim of the present study is to describe the metabolic activity of cysts in patients with cystic echinococcosis through FDG-PET.
METHODS: Prospective observational study where adult patients diagnosed of cystic echinococcosis were offered to undergo FDG PET/CT before treatment onset. Demographic, clinical, radiological, and histopathological information was collected from all patients.
RESULTS: Sixteen patients were included, 50% were male, and age ranged from 18 to 85 years. Most of the patients had liver involvement, and all patients had CE3, CE4 or CE5 stage of the WHO-IWGE classification. Only one patient (CE5) had an increased 18F-FDG uptake of the cyst in the FDG PET/CT. From the 5 patients who underwent surgical treatment, only one showed signs of viability of the cyst: a patient with CE5 with no increased 18F-FDG uptake of the cyst.
CONCLUSIONS: In our pilot study, we did not find the correlation between the FDG PET/CT imaging and the cystic echinococcosis cyst bioactivity.

OBJECTIVE: The purpose of this study was to evaluate the outcomes of multiple debridement of cavity lesion combined with anti-parasitic chemotherapy in the treatment of mid or advanced spinal echinococcosis, and to document the complications, bone and functional outcomes.
METHODS: From January 2007 to February 2019, the medical records and imaging were evaluated retrospectively of all patients with mid or advanced spinal echinococcosis, who were treated by multiple debridement of cavity lesion. The Braithwaite and Less classification system of spinal echinococcosis and the Frankel Classification System was utilized evaluate the results of preoperative and postoperative recovery.
RESULTS: Between January 2007 to February 2019, a total of 33 patients met the criteria were included in this study with a mean postoperative follow-up time of 4.9 (1 to 10) years. There were 18 males (54.5%) and 15 females (45.4%), with a mean age of 41.5 years (range, 23 - 70 years). The satisfactory recovery of lower limb motor function were presented in 32 patients. Of the 24 patients (72.7%) with recurrence of spinal echinococcosis.
CONCLUSIONS: Multiple debridement, spinal cord decompression combined with anti-parasitic chemotherapy after surgery, are effective methods to delay or prevent the process of disease or recurrence. The recurrence of infection is common in most cases, and CT and MRI are the preferred methods of diagnosing this disease.

OBJECTIVE: We prospectively compared the clinical outcomes of radical and conservative surgical procedures for primary liver hydatid cysts, additionally radical surgical procedures with and without the two-month administration of albendazole after the operation were compared.
METHODS: Overall, 90 patients undergoing open surgical treatment for liver hydatid cysts were divided into three surgical groups: first group, patients who underwent radical surgery (pericystectomy) followed by albendazole treatment for 2 months following the operation group; second group, patients who underwent radical surgery(pericystectomy) without receiving albendazole after surgery group; third group, patients, who underwent conservative surgery (partial cystectomy) with albendazole treatment after surgery. The clinical outcomes and rate of recurrence were analyzed in follow-up period.
RESULTS: The mean surgery duration in the Radical groups was significantly longer in comparison to the Conservative surgery + Albendazole group. (212.0 and 202.5 min vs. 173.2 min; p < 0.05). Blood loss in the Radical groups was significantly higher in comparison to the Conservative surgery + Albendazole group (218.3 and 174.6 ml vs. 67.2 ml; p < 0.05). However, postoperative complication rate in the Radical group was significantly lower in comparison to Conservative surgery + Albendazole group (13.3% [n = 4] and 6.7% [n = 2] vs. 36% [n = 11]; p < 0.05). The postoperative hospital stay in both Radical groups was significantly lower in comparison to the Conservative surgery + Albendazole group (7.9 and 7.4 days vs. 11.3 days; p < 0.05).
CONCLUSIONS: In comparison to conservative surgery, radical surgery is a preferable treatment modality for patients with active liver hydatid cysts. Postoperative albendazole treatment is preferable, regardless of the type of surgical procedure.
