Due to advancement in treatment modalities for the last two decade the survival rate of retinoblastoma has increased. But long term follow up is mandatory for retinoblastoma survivor as there is risk for development of second cancers in later life. Proper genetic screening and genetic counseling can help parents and patients in their adulthood to understand the disease properly.Recently, mucormycosis, extremely rare fungal infections are emerging as a matter of concern in COVID-19. The saprophytic fungi of Mucorales species cause the disease, Mucormycosis, only in immunocompromised hosts. Clinical presentation of mucormycosis is related to the underlying conditions; rhino-cerebral disease is the most common form, especially in patients with diabetes mellitus; pulmonary, cutaneous, or gastrointestinal infections can also occur. Severe COVID-19 itself is a life-threatening disease and various factors, including diabetes, especially when complicated by ketoacidosis, previous respiratory pathology, immunosuppressive therapy, nosocomial infection sources and systemic immune alterations of COVID-19 itself predispose to mucormycosis. No specific biomarkers are available to diagnose mucormycosis; imaging of the involved area and histopathological examination of the biopsied tissue are most important in diagnosis. The underlying medical conditions must be corrected; these include good glycemic control, tapering of steroids, and reducing or stopping immunosuppressive medications. Systemic antifungal therapy with liposomal Amphotericin B is the medical treatment of choice though drug resistance is not uncommon. Surgical debridement of devitalized tissue is often required. Severe COVID-19 patients with secondary co-infections require longer hospitalization and had higher risks of death. The mortality rate is almost 50% despite timely adequate treatment. The judicious use of systemic glucocorticoids and immunosuppressive agents for treating severe disease and hyperglycemia control seems vital for preventing and managing mucormycosis.Norovirus, often called winter vomiting bug, is the most common cause of outbreaks of acute gastroenteritis in all age groups all over the world. It was discovered in 1972; belong to the genus Norovirus in the family Caliciviridae. Based on genomic organization and phylogenetic analysis, the family Caliciviridae is divided into four genera- Norovirus, Sapovirus, Vesivirus and Lagovirus. The aim of this review article was to find out the present status of prevalence and evolution of norovirus strains in developed and developing countries. In this article various literature on norovirus from different countries was reviewed. The detection of norovirus in the lower middle income countries (LMIC) was reported 15% in cases and 8% in controls during 1997 to 2018. On the other hand, detection rate of norovirus in low income countries (LIC) was 11% in cases and 9% in controls during the same period. Overall detection rate of norovirus was 14% in LIMC and 8% in LIC during 1997 to 2018. Noroviruses are divided geneticar, headache and stomach pain. It may be complicated with dehydration and electrolyte imbalance. Gastroenteritis develops 12 to 48 hours after exposure and recovery typically occurs within 1 to 3 days. There is no specific treatment of norovirus gastroenteritis. Prevention includes proper hand washing and cleaning or disinfection of contaminated surfaces. Various genotypes of norovirus may be circulating around the world and can emerge either nationally or globally. In this overview, general characteristics of norovirus, current status of genomic diversity and classification, recent status of norovirus gastroenteritis outbreaks in the developed and developing countries is outlined for comprehensive understanding of the present status of prevalence and evolution of norovirus strains to develop strategies for prevention and control of norovirus infection in human.Dermoid cysts (DC) are benign cutaneous developmental anomalies comprising of hair follicles, sweat glands and sebaceous glands, and lined by stratified squamous epithelium. They are most commonly found on the face, lower back, and ovaries. We present a case of DC with intracranial extension in a 9 year old boy who presented with headache and a fluctuant scalp swelling. Magnetic resonance imaging revealed a midline scalp mass with intracranial extension. The lesion was excised with superior sagittal sinus preservation; and confirmed as DC by histopathological examination. The boy made good recovery.Management of critically ill obstetric patients is a great challenge for the ICU team. The safety of both mother and fetus are of real concerns. Teamwork is essential for better outcome in obstetric patients in the ICU. A 26 years old female was admitted in Dhaka Medical College Hospital, Dhaka, Bangladesh on 18 August 2019 with 7 months pregnancy with brain tumor (later diagnosed as Gliosarcoma) and was managed surgically by left temporal craniotomy with excision of the tumor. The patient was shifted to the ICU due to repeated convulsions and need mechanical ventilator support. Later on, she was suffering from sepsis with pseudomonas in blood culture, grade IV pressure ulcer and electrolyte imbalance and needed tracheostomy for airway management. On 34th weeks of her pregnancy she developed antepartum hemorrhage with respiratory distress. Emergency LUCS was done and she delivered a LBW baby who was managed in NICU. Mother was managed in the ICU and later on both mother and child were discharge with good conditions. Multidisciplinary team work is vital for better management of critically ill obstetric patients.Angiomyolipomas (AML) are benign tumor of kidney also referred as renal hamartoma composed of varying amounts of mature adipose tissue, smooth muscle, and blood vessels. It is seen in two distinct clinical forms, a sporadic (isolated) form and 55-80% seen in association with Tuberous sclerosis complex (TSC). If the lesion grows to a large size, a series of clinical manifestations and serious complications may occur. Here we present a case of 26 years lady who presented in the Department Radiology & Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh with chief complaints of bilateral loin pain and occasional hematuria for 2 months. https://www.selleckchem.com/products/bgj398-nvp-bgj398.html Ultrasound abdomen and contrast enhanced computed tomography shows bilateral renal angiomyolipoma (left>right). In order to look for tuberous sclerosis features, we followed her with plain computed tomography of head which shows subependymal calcifications.
