Thromboprophylaxis Outcome in Childhood SARS-CoV-2 Infection: A Single-Center Experience.

BACKGROUND: The SARS-CoV-2 infection has been associated with potentially endothelial damage and coagulation cascade activation that cause thrombosis. There is limited information on thrombosis and anticoagulant therapy in children with coronavirus disease 2019 (COVID-19). AIMS: This study evaluates the outcome of thromboprophylaxis in children younger than 18-year old with COVID-19 infection. METHODS: A retrospective study was conducted on 184 hospitalized pediatric patients with confirmed COVID-19 infection. A designed questionnaire was made to collect all demographic, clinical, and laboratory data. According to World Health Organization, the patients were classified as asymptomatic/mild, moderate, severe, and critically ill. RESULTS: The mean age of the patients was 7.04±5.9 (1 wk to younger than 18 y). Overall, 33 patients received anticoagulant therapy. All patients who passed away (n=19) belonged to the critical group. One patient (1.28%) was complicated with deep vein thrombosis despite taking thromboprophylaxis, and 1 (1.28%) with pulmonary thromboembolism while the patient did not take an anticoagulant. CONCLUSIONS: Our data showed a lower rate of thrombosis (1.4%) than adult patients with COVID-19. It may underline the role of anticoagulants in moderate to severe/critically ill children with COVID-19 infection. Expert opinion and personal experience are necessary, while we have a significant knowledge gap in understanding COVID-19-associated coagulopathy and thrombotic risk in children.

Gastro-intestinal basidiobolomycosis in a 2-year-old boy: dramatic response to potassium iodide.

Gastro-intestinal basidiobolomycosis (GIB) is a rare fungal infection caused by Basidiobolus ranarum. Treatment includes surgical resection and long-term antifungal therapy. A 2.5-year-old boy presented with a 10-day history of abdominal pain, fever and diarrhoea, and a palpable abdominal mass was detected. Resection was undertaken and histology confirmed basidiobolomycosis. Treatment with amphotericin B and itraconazole was commenced, but the infection progressed and spread to involve the intestines, liver, ribs and lung, and also the abdominal wall after 6 months, requiring four operative procedures. Because of unresponsiveness to amphotericin and itraconazole, oral potassium iodide was added which resulted in complete resolution of the infection. Potassium iodide is an essential component of the treatment of systemic B. ranarum.

Analysis of hospital records of children with hydatid cyst in south of Iran.

The clinical manifestations of hydatidosis are various and related to anatomic location. Defining frequent symptoms and signs of the disease is imperative for early management of it. The aim of this report was to analyse the clinical features of infected children with hydatid cysts located in different organs. In this study, medical charts of 57 children between 3 and 16 years of age with hydatid cyst admitted to Pediatric Wards of Nemazee Hospital were evaluated over a 12 year period (from 2003 to 2014, prospectively). All the epidemiologic, clinical, paraclinical and therapeutic data were collected. The frequencies of hydatidosis in males and females were 42.1 and 56.1%, respectively. Hydatid cysts were found in the liver and lungs in 59.6 and 33.3% patients respectively and 2 patients had an asymptomatic cyst in the heart with concomitant liver and lung cysts. The right upper quadrant pain (100%) was the most common symptom in the liver cysts. Phlegm (78.9%), Dyspnea (57.9%), acute (47.4%) and chronic cough (47.4%) were mostly seen in lung hydatid cysts. Some symptoms such as fever (68.4%) and weakness (59.6%) were the most common presenting symptoms in both groups. All children were treated through surgical approaches plus medical treatment. In the present report, liver was the most common site of involvement in children. Liver hydatidosis should be considered in children with upper quadrant pain and pulmonary hydatidosis in children complaining of phlegm and dyspnoea.

Molecular Epidemiology of Enteric Adenovirus Gastroenteritis in under-Five-Year-Old Children in Iran.

Background. Acute gastroenteritis is one of the major sources of morbidity and mortality among young children in developed and developing countries. The aim of this study was to determine the prevalence of human adenovirus- (HAdV-) 40 and HAdV-41 in children hospitalized with gastroenteritis in five different health centers of Iran. Methods. In a cross-sectional epidemiological study, we studied 2682 fecal specimens that were collected from children under the age of 5 years in five educational and therapeutic pediatric centers in Iran from February 2012 to February 2013. Samples were tested for HAdV-40 and HAdV-41, using a specific pair of primers in polymerase chain reaction (PCR) method. Results. HAdV-40 and HAdV-41 were detected in 132 (5.18%) of the patients with diarrhea. A significantly higher prevalence of HAdV-40 and HAdV-41 (58.3%) was observed in children under 12 months of age, compared to other age groups. The male to female ratio was 1.7. Conclusion. The results of this study demonstrated that HAdV-40 and HAdV-41 could be considered etiological agents for acute gastroenteritis among children in Iran. The PCR as a rapid test may increase the chance for a relatively mild course of the disease followed by a complete recovery and avoiding administration of unnecessary antibiotics.

A child with intestinal basidiobolomycosis.

Fungal infections of the gastrointestinal tract are not common in children, especially in immunocompetent ones. In this case report we describe a child who was presented with abdominal pain and mass, bloody diarrhea and fever. He was treated for amebiasis, but due to treatment failure and deterioration of his condition, he underwent a laparatomy. Histologic examination of the excised bowel in the second look revealed Basidiobolomycosis, a fungus belonging to the order Entomophthorales. The signs, symptoms, treatment and diagnosis of the present case indicate that fungal infections must be considered not only in immunocompromised patients with abdominal pain and mass, but also in apparently immunocompetent ones.
