Cystic echinococcosis (CE) is a parasitic zoonosis caused by E. granulosus primarily affecting the liver and lungs. CE of the bone is by far the most debilitating form of the disease and is very difficult to manage as it mimics malignant tumors. We reviewed bone CE cases admitted to a reference oncological hospital in Kazakhstan from January 2010 to February 2017. Among eight patients, the mean age was 33.5 years, and the male/female ratio was 1 : 3. Patients were examined by X-ray (8/8), CT (7/8), and MRI (3/8). CE was in the spine (2 cases), pelvis (3 cases), and long bones (humerus, tibia, and femur; one case for each). All patients were treated surgically. No perioperative albendazole was administered. No patient received albendazole afterwards. The mean hospital stay was 25 days. Interventions are urgently needed to assess the burden of CE in Kazakhstan and to inform clinicians of the existence of the disease. [ABSTRACT FROM AUTHOR]

Lung is the second most common locationof cystic echinococcosis (CE), after the liver. Diagnosis of lung CE is often incidental, and clinical manifestations depend on the location and size of the cyst, the most common being chest pain, shortness of breath, expectoration of fragments of endocyst, and haemoptysis. Surgery is the primary treatment, with a minor role for medical therapy. Delayed diagnosis and treatment may have important consequences. We present a case of lung CE in whichsurgical treatment was delayed due to the first wave of COVID-19. Since surgery could not be performed immediately, the patient was kept on albendazole and the cyst stage moved from CE1 to CE3a, to CE4, eventually requiring a more aggressive pericystectomy instead of the commonly performed endocystectomy. The clinical and imaging characteristics of a rare CE4 cyst of the lung are reported. [ABSTRACT FROM AUTHOR]

Necrotizing fasciitis (NF) is a soft tissue infection affecting subcutaneous tissue and the muscular fascia without involvement of the muscle and can be either monomicrobial or polymicrobial. Monomicrobial infections are usually caused by group A streptococci, while infections caused by anaerobic germs usually affect immunodepressed patients. We report a rare case of NF caused by two anaerobic bacteria in an immunocompetent patient. [ABSTRACT FROM AUTHOR]
