An 11-Year-Old Saudi Arabian Girl Who Presented with Multisystem Inflammatory Syndrome in Children (MIS-C) Associated with SARS-CoV-2 Infection with Coronary Artery Aneurysm and Cardiac Involvement: A Case Report.

BACKGROUND Early in the COVID-19 pandemic, children who were infected with severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) with vascular inflammation were described as having a vasculitis similar to Kawasaki's disease. There are now consensus clinical guidelines that have described the presentation and diagnosis of multisystem inflammatory syndrome in children (MIS-C) associated with SARS-CoV-2 infection. This report aims to describe a case of MIS-C in an 11-year-old Saudi Arabian girl who presented with coronary artery aneurysm and cardiac involvement. CASE REPORT We describe an 11-year-old Saudi girl who was asymptomatic for 3 weeks after contracting SARS-CoV-2. Three weeks after suffering a mild flulike illness, she developed a high fever, cough, and severe clinical deterioration within 12 h of admission, including shock, rash, pleural effusion, high inflammatory markers, and a coronary aneurysm. As per current practice, the diagnosis was confirmed as multisystem inflammatory syndrome based on a SARS-CoV-2 test with reverse transcription polymerase chain reaction (RT-PCR) from 2 nasopharyngeal aspirates. Her condition was successfully treated with antibiotics, inotropes, IVIG, aspirin, and Tocilizumab, in addition to high-flow oxygen therapy. Eventually, she was able to return home after fully recovering. CONCLUSIONS The findings in this report suggest that children with MIS-C due to SARS-CoV-2 infection can have a good prognosis, even when they suffer from coronary artery and cardiac involvement. The increasing number of emerging SARS-CoV-2 variants that affect children supports the importance of RT-PCR for the COVID-19 diagnostic test for children with multisystem or cardiovascular inflammation, which may guide the most appropriate clinical management of the variants of MIS-C.

Birth prevalence and pattern of osteochondrodysplasias in an inbred high risk population.

BACKGROUND: Define the pattern and birth prevalence of the different types of osteochondrodysplasias in newborn infants in the United Arab Emirates (UAE) population, which is highly inbred and where termination of pregnancy is not accepted. METHODS: All infants with a birth weight of 500 gm and above in the three hospitals in Al Ain Medical District of the UAE were studied prospectively over a period of 5 years. For each live birth or stillbirth with suspected skeletal dysplasia, a detailed clinical and radiological examination was carried out. Pregnancy history and information regarding parental age, ethnic origin, family history, and level of consanguinity were obtained and a pedigree was constructed. RESULTS: Among the 38,048 births during the study period, 36 (9.46/10,000 births) had some type of skeletal dysplasia. Eighteen cases were attributed to autosomal recessive genes (4.7/10,000 births), 10 were due to apparent new dominant mutations (2.62/10,000), five were autosomal dominant type (1.3/10,000) and one was X-linked dominant type (0.26/10,000). In three cases, inheritance was unknown. The most common recessive type of skeletal dysplasia in our series was fibrochondrogenesis (1.05/10,000), followed by chondrodysplasia punctata (0.78/10,000). The birth prevalence rate of skeletal dysplasia doubled in the last 2 years of the 5-year observation period (6.74/10,000 in 1996 vs. 12.86/10,000 in 1999, and 13.45/10,000 in 2000). This increase involved cases caused by new dominant mutations, and occurred mainly in the first half of 1999. CONCLUSION: This prospective study has identified a high birth prevalence of skeletal dysplasia, and risk factors are postulated. These findings represent an accurate birthprevalence figure and a useful baseline for this group of birth defects in the UAE.
