Kawasaki disease in children from Dubai, United Arab Emirates (2012-2020): a single-centre retrospective clinical case series.

Kawasaki disease (KD) is most common among East Asian children. There is a lack of data from Middle Eastern countries. We conducted a retrospective study of 27 paediatric patients with KD in Dubai, United Arab Emirates, 2012-2020. The majority of the patients were male, Asian, aged 1-5 years and presented with typical (complete) KD. Timely high-dose intravenous immunoglobulins were administered to 18 patients. Twelve patients did not develop any cardiac complications, 12 had a coronary artery aneurysm and 2 patients developed serious cardiac complications . No patient experienced non-cardiac complications or died. Paediatric patients with KD in Dubai were similar to those from other countries.

Kawasaki Disease Presenting with Bloody Diarrhea and Acute Renal Failure: First Case.

Kawasaki disease (KD) is an acute febrile vasculitis of an unknown cause. It affects children <5 year of age, even if cases over 5 years old have been also reported. It is the commonest cause of acquired heart diseases in children which may lead to serious morbidity and mortality. The complications and mortality increase when the diagnosis is delayed. One of the main reasons leading to delayed diagnosis and consequent delayed treatment is the unusual presentation of KD. Its unusual manifestations have been increasingly reported to jeopardize the timely diagnosis and proper treatment. As there is not yet available blood test to diagnose it, low threshold should be taken into account for considering KD, when the clinical criteria are not typical. KD with renal manifestations is infrequently described. We present and discuss a case of an unusual presentation of KD presenting as bloody diarrhea and acute renal failure.

Recurring Facial Erythema in an Infant.

Causes of facial rashes and erythema in infants are many but rarely only happen during feeding times which are commonly and sometimes wrongly attributed to food allergy. There is a rare condition called Auriculotemporal nerve syndrome that is characterized by recurrent episodes of gustatory facial flushing and sweating along the cutaneous distribution of Auriculotemporal nerve: the so-called Frey syndrome. This condition is most frequently observed in adults usually after parotid surgery. It is rare in children and is mostly attributed to forceps assisted delivery. It can also be misinterpreted as food allergy. Here we report a case of an infant with Frey syndrome without any history of perinatal trauma, which was considered initially as food allergy and highlights the importance of distinguishing it from food allergy.

Bruises Around the Umbilicus in an Infant.

The most common causes of umbilical discharge in infancy are infection and umbilical granuloma that may be treated by antibiotics and topical application of silver nitrate subsequently. If the umbilical discharge persists or if there is any abnormal discoloration around the umbilicus, it is important to investigate for underlying congenital abnormality that may be cured by surgical intervention. Unusual presentation of omphalomesenteric duct cyst has been reported in literature. We report, for the first time as far as our search is concerned, a case of a 16-month-old infant who presented initially with persistent umbilical discharge and finally with bruising around the umbilicus in keeping with Cullen's sign. A diagnosis of omphalomesenteric duct cyst containing pancreatic tissue was made on histopathological examination. This case emphasizes that, a persistent umbilical discharge and or discoloration around the umbilicus should be further investigated and an omphalomesenteric duct cyst can present as Cullen's sign.
