Abdominal Tuberculosis in Children: A Case Series of Five Patients.

Tuberculosis remains (TB) to be one of the most common causes of child morbidity and mortality. Abdominal TB is not frequently diagnosed and, although its incidence is not definitively established, there are data that seem to indicate that it accounts for approximately 1-3% of all pediatric TB cases and for no more than 10% of those with extrapulmonary manifestations. It seems, however, that abdominal TB is significantly more common than usually thought as signs and symptoms are non-specific and may mimic other diseases.

COVID-19 in Children: Update on Diagnosis and Management.

In December 2019, a new infectious disease called coronavirus disease 2019 (COVID-19) attributed to the new virus named severe scute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detected.

Management of Infectious Lymphadenitis in Children.

Lymphadenopathy is an irregularity in the size and texture of the lymph nodes, which is quite common in childhood. When the enlargement of lymph nodes is caused by inflammatory and infectious processes, it is called lymphadenitis.

The Dose Makes the Poison: A Case Report of Acquired Methemoglobinemia.

Methemoglobinemia (MET) should be suspected in cases where cyanosis is not associated with signs and symptoms of lung and/or heart disease, or in a cyanotic child exhibiting discrepancies in the partial pressure of oxygen in the arterial blood, the blood oxygen saturation, and the clinical assessment. A 10-month-old girl was taken to the Pediatric Emergency Department for the acute, sudden development of significant peroral cyanosis associated with gray pigmentation of the skin. The problem was evidenced approximately one hour after she ingested a homemade puree of mixed vegetables, mainly composed of potatoes and chards that had been prepared three days before and had been kept in the refrigerator since then.
