Purpura fulminans secondary to varicella-zoster virus infection.

BACKGROUND: Purpura fulminans (PF) is a rare, life-threatening condition involving consumptive coagulopathy and intravascular thrombosis, causing purpura and necrosis in the skin and soft tissue. CASE REPORT: A 4-year-old Tajik girl with PF secondary to varicella-zoster virus (VZV) infection presented with purplish red, diffuse, painful lesions localized to the entire right leg. Her vaccination status was unknown, and she did not have concurrent chronic illness. Ten days before admission, the girl was admitted to another hospital in Tajikistan with a diagnosis of chickenpox and PF. She was then transferred to the hospital of the authors of the current report due to the enlargement of lesions to the gluteal region, a change in the color of lesions from red to black, and the detection of arterial thrombosis via Doppler ultrasonography. Multiple surgical debridements were performed to manage tissue necrosis, and the patient's right leg was amputated at the 18th week of admission. The patient was discharged after 26 weeks of hospitalization. CONCLUSION: Although VZV infections mostly cause mild and self-limiting eruptive disease, they can progress, with life-threatening complications, including PF. To prevent VZV infection and resulting complications, immunization with live attenuated vaccines and maintaining population immunity above a certain threshold are the most important strategies to prevent the circulation of the virus.

A 4-Year-Old Child with a Giant Cerebral Hydatid Cyst: A Case Report.

Echinococcosis is the most common cestode infection globally caused by the Echinococcus species. The most common organ involvement is the lungs and liver, but other organs can be rarely involved. Here, we present a case with a giant cerebral hydatid cyst. A 4-year-old boy presented with abnormal gait and walking at Marmara University School of Medicine Pendik Training and Research Hospital, Istanbul, Türkiye in September 2022. Cranial magnetic resonance imaging showed a cyst of 13 cm in diameter. The cyst was enucleated successfully with no rupture. Oral albendazole therapy was started. There was no eosinophilia, and the echinococcal indirect hemagglutination test was negative. Ultrasonography detected an anechoic cystic lesion in the liver. He was evaluated for deep-organ involvement; however, no cysts were detected in other organs. The histopathological examination was compatible with a hydatid cyst. Although intracranial hydatid disease in children is rare, it should be considered among the differential diagnoses in patients with neurological symptoms, especially in endemic regions.

COVID-19 in hospitalized infants aged under 3 months: multi-center experiences across Turkey.

To investigate coronavirus disease 2019 (COVID-19) in infants aged 0 to 3 months because there is currently a significant gap in the literature on the subject. A cross-sectional study was conducted with the involvement of 19 medical centers across Turkey and 570 infants. The majority of the patients were male (58.2%), and the three most common symptoms were fever (78.2%), cough (44.6%), and feeding intolerance (39.9%). The results showed that a small percentage of infants had positive blood (0.9%) or urine cultures (10.2%). Most infants presented with fever (78.2%). Children without underlying conditions (UCs) had mostly a complicated respiratory course and a normal chest radiography. Significant more positive urine culture rates were observed in infants with fever. A higher incidence of respiratory support requirements and abnormal chest findings were seen in infants with chronic conditions. These infants also had a longer hospital stay than those without chronic conditions.  Conclusions: Our study discloses the clinical observations and accompanying bacterial infections found in infants aged under 3 months with COVID-19. These findings can shed light on COVID-19 in infancy for physicians because there is limited clinical evidence available. What is Known: • COVID-19 in infants and older children has been seen more mildly than in adults. • The most common symptoms of COVID-19 in infants are fever and cough, as in older children and adults. COVID-19 should be one of the differential diagnoses in infants with fever. What is New: • Although most infants under three months had fever, the clinical course was uneventful and respiratory complications were rarely observed in healthy children. • Infants with underlying conditions had more frequent respiratory support and abnormal chest radiography and stayed longer in the hospital.
