Kawasaki disease (KD) is a vasculitis mostly seen in children aged less than 5 years. It can involve different organs and tissues. Its diagnosis is based on the clinical criteria of the American Heart Association (AHA). We report a case of a Moroccan adolescent with an atypical presentation of KD initially treated as typhoid fever. Gastrointestinal, renal, and pulmonary signs were the main clinical findings that made the diagnosis of KD challenging and delayed. The consequence was a severe cardiac damage with myocarditis and coronary artery dilation. KD is uncommon in adolescents, and it is important to recognize the atypical forms and the different presentations of KD in order to prevent the delay of diagnosis and treatment, and hence the cardiac complications.
Background β‐thalassemia syndromes are the most common hereditary blood disorders in the world and are recognized as a major health problem in Morocco. They are characterized by the reduction or the absence of β‐globin chain synthesis. The severity of the disease depends on the nature of the variants affecting the β‐globin gene ( HBB ), and each ethnic group has its own mutation spectrum. Hereby, we present, for the first time, the molecular profile of β‐thalassemia in the Eastern region of Morocco. Methods This study concerns 39 cases from 33 families who were enrolled in the BRO Biobank. Nineteen were diagnosed with β‐thalassemia major and 20 with β‐thalassemia minor. To detect mutations of the β‐globin gene, we have used RFLP‐PCR and Sanger sequencing. Results Nine known β‐thalassemia variants have been identified. Among these, we reported, for the first time in the Moroccan population, the Czechoslovakian variant C38/39(‐C) at homozygous state. The C39(C > T) was the most frequent variant (72.54%), followed by FSC5(‐CT) (5.88%), FSC6(−A), IVS‐1‐110(G > A), −29(A > G), C38/39(‐C) (3.92% each), and finally by IVS‐I‐1(G > A), IVS‐II‐1(G > A), and −56(G > C) (1.96%). Of particular interest this mutational spectrum of β‐thalassemia is very different from that found in previous studies in Morocco or in other North African countries. Conclusion This study is the first contribution to the description of the molecular profile of β‐thalassemia in the Eastern region of Morocco. It shows the high molecular heterogeneity of β‐thalassemia in our country. Therefore, these results can be valuable for the implementation of carrier screening, genetic counseling, and prenatal diagnosis programs.
Cutaneous presentation revealing acute myeloid leukemia (AML) is rare, and the prognosis is poor. We report a case of an 11-month-old male who presented with cutaneous lesions present as diffuse purplish papulo-nodular lesions, revealing M5 acute myeloid leukemia. Skin biopsy and immunohistochemical examination, combined with routine blood analysis and bone marrow examination, contributed to early diagnosis. However, despite intensive chemotherapy treatment, the prognosis was poor and death occurred during the first months of treatment.
Background With the wide spread of the current SARS-CoV-2, It was found that about 2% of children was affected according to several studies, However, a small number of children with Covid-19 develop a significant systemic inflammatory response similar to Kawasaki disease, a new disease entity called multisystem inflammatory syndrome. Methods A 12-year-old child, without a notable pathological history, who presented to the emergency, during the SARS-CoV-2 pandemic, for management of a pseudo-appendicular syndrome. Our patient was initially assessed by the surgical team due to his query acute abdomen. The pain had been evolving for 3 days associated with several episodes of bilious vomiting in a context of fever at 38.5°. Abdominal examination noted abdominal tenderness and defence. Extradigestive signs were not reported, The Lab Testing objectified a CRP at 235, elevated white blood cells at 18 180, an abdominal ultrasound was requested returning without particularities. Faced with the persistence of bilious vomiting, surgical exploration was indicated objectifying a catarrhal appendix. A pediatric opinion was requested, the clinical examination shows conscious child who presents infra cervical lymphadenopathy with a fever at 38 associated with an erythematous skin rash on the back and aseptic conjunctivitis. The Lab Testing objectified an important inflammatory syndrome, a acute kidney and heart failure a Covid 19 serology was requested with positive IGG, négative IGM, PCR covid test was negative, given the unavailability of In immunoglobulins, the treatment was based on corticosteroid bolus then relay by oral corticosteroid associated with an anti-inflammatory treatment, gastric protection by proton pump inhibitors, treatment of heart and acute kidney failure. The evolution was marked by clinical and biological improvement Discussion Coronavirus 2 (SARS-CoV-2) infection among children and adolescents, is mainly responsible for mild respiratory symptoms, in contrast to the severe forms reported in adults [7]. A systemic inflammatory syndrome mimicking kDa, temporally associated with infection with SARS-CoV-2 (Kawa-COVID-19) has recently been described as a serious illness sometimes requiring intensive care (44%). The median age is older (> 5 years), the frequency and severity of myocarditis are very different from classic kDa, abdominal pain and/or diarrhea were more frequently (81%) reported than in classic kDa, heart failure, pneumonia, neurological and renal impairment, associated with elevated CRP, hyperferritinemia are more common in Kawasaki-Like syndrome [10]. Some investigations must be systematically realized urgently to diagnose potentially fatal complications. These include testing for myocarditis, patients should benefit from careful monitoring and treatment with IV Ig 2 g/kg should be administered rapidly and seems to be effective in the majority of cases, associated anti-inflammatory therapy, such as steroids is necessary Conclusion Pediatricians should be aware of these atypical presentations of COVID-19 infection for early diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
