A Case Report of an Uncommon Association of Total Intracardiac Anomalous Pulmonary Venous Return and Tetralogy of Fallot.

Total anomalous pulmonary venous return (TAPVR) represents a group of anomalies consisting of a lack of connection between the pulmonary veins and the left atrium. All oxygenated pulmonary venous return flows directly or indirectly into the right atrium. Survival is only possible with a right-to-left atrial shunt. It remains rare, accounting for less than 1% of all congenital heart diseases. Its association with tetralogy of Fallot is much rarer and has been documented in medical literature as isolated cases. Early prenatal diagnosis, rapid surgical repair, and optimal postoperative resuscitation appear to be the best guarantee of a favorable outcome following total repair of a pulmonary venous connection anomaly. Non-obstructed forms present as high-flow shunts with moderate cyanosis. The symptomatology of blocked forms is dominated by the obstruction to venous return; a clinical picture of respiratory distress with intense cyanosis and severe pulmonary arterial hypertension develops from the first days of life. Echocardiography is fundamental in diagnosing TAPVR. If the results are inconclusive, magnetic resonance imaging and computed tomography are appropriate alternatives for establishing a complete and accurate diagnosis. We report a case of a two-month and 22-day-old infant who is a product of a twin pregnancy, presenting with a non-obstructed TAPVR associated with tetralogy of Fallot, and his twin who died on day 20 of life, likely due to a complex cyanotic congenital heart disease.

A Rare Case Report of Benign Intracranial Hypertension Caused by Hypervitaminosis A.

Benign intracranial hypertension (BIH) in children is recognized as elevated intracranial pressure without hydrocephalus or intracranial mass. It manifests differently in adults, with no apparent predilection for sex or weight. Headache, papilledema, and possibly sixth nerve palsy with visual field defects are the typical symptoms of this syndrome. Vitamin A toxicity is a rare cause of BIH. We report the case of a previously healthy 13-year-old girl presenting with photophobia, a frontal headache, and vomiting. She had bilateral papilledema discovered by fundoscopy. Both magnetic resonance imaging and brain CT were normal. At admission, a lumbar puncture (LP) revealed an opening pressure of 26 cm H2O with normal cerebrospinal fluid (CSF) analysis. The diagnosis of BIH was established, and treatment with acetazolamide was started, with good clinical results. Regular eye evaluations showed a regression of papilledema. Elevated serum vitamin A levels were the only positive findings. Within two weeks, the patient was discharged without any symptoms. This study aims to attract the attention of clinicians to the importance of evaluating vitamin A toxicity in the context of papilledema and oculomotor problems in a child who has undergone normal neuroradiological investigations.

Acute Myocardial Infarction in a Seven-Year-Old Child With Type 1 Diabetes: A Rare Case Report.

Myocardial infarction (MI) is extremely rare in children and can have different etiologies, including congenital heart defects and Kawasaki disease. Cardiovascular disease (CVD) is the primary cause of death in patients with type 1 diabetes (T1D). Effective management of risk factors like blood pressure, cholesterol, and blood sugar levels is essential for individuals with T1D to mitigate the risk of cardiovascular complications, including MI. We present the case of a seven-year-old child diagnosed with type 1 diabetes one month before this admission, without any other notable medical history, who was admitted to the pediatric emergency department due to chest pain. The symptoms had begun two hours prior to admission. Upon arrival, the patient reported severe and persistent retrosternal constrictive chest pain radiating to the left arm without other associated signs, with a strictly normal clinical examination. An electrocardiogram (ECG) revealed typical ST segment elevation in inferior leads (II, III, and aVF) with reciprocal changes in V1 to V4. Troponin level was elevated at 7254 ng/l. Echocardiography revealed mild dilation of the left coronary artery (4 mm) and the right coronary artery (3 mm), while other radiological and laboratory investigations showed no abnormalities. The patient responded well to treatment with acetylsalicylic acid, clopidogrel, and heparin, resulting in a favorable outcome.

Exploring the Link Between Profuse Warts and Hyper-Immunoglobulin E (IgE) Syndrome: A Pediatric Case Report.

The relationship between warts and hyper-immunoglobulin E (IgE) syndrome lies in the fact that patients with this syndrome may have recurrent or persistent skin warts because of their immune dysfunction. Therefore, it is important to consider this possibility when evaluating a patient with skin warts, especially if they are associated with other symptoms such as recurrent infections or pulmonary issues. Warts can thus be an important clinical sign indicating the presence of this syndrome. We report the case of a young girl presenting with numerous warts accompanied by pulmonary involvement and weight delay, in whom the diagnosis of hyper IgE syndrome was established.

Ophthalmic Shingles in Children: A Rare Form and a Danger to Be Aware of.

Shingles in children is rare, especially the ophthalmic form. The occurrence of shingles in children is exceptional but often benign, requiring only symptomatic treatment. Antivirals are exceptionally used for complicated forms, which are mainly seen in immunocompromised individuals or in ophthalmic locations that can lead to severe ocular complications. Various studies agree on the benign nature of this condition in immunocompetent children and an excellent prognosis. We report a case of ophthalmic shingles in an immunocompetent child aged two years and seven months. The purpose of this clinical case was to emphasize the importance of early antiviral treatment to limit corneal involvement and preserve visual function.

A rare case of steroid 11 beta-hydroxylase deficiency in a child revealed by acute pulmonary edema.

We report the case of a 5-year-old boy diagnosed with congenital adrenal hyperplasia due to 11-hydroxylase deficiency, revealed by disorders of sex development (DSD) and acute pulmonary edema due to severe hypertension. We considered the diagnosis based on biological and radiological examinations. The sociocultural background and the delayed diagnosis had a significant impact on the therapeutic decisions. All babies should be screened for 11 beta-hydroxylase deficiency, there should be specialized and interdisciplinary medical centers, and early detection is essential to avoiding serious complications of this disease.

Exceptional case of a hemangioma-like rabdomyosarcoma in the hand's palm.

Rhabdomyosarcoma is a malignant tumor in children that might mimic a benign tumor, such as infantile hemangioma, particularly when detected early. Although rhabdomyosarcoma rarely occurs in the hand, its prognosis is generally poor, and successful treatment relies on a complete and radical surgical excision. We present a case of rhabdomyosarcoma located in the palm of an infant's hand, initially presenting clinical and radiological features suggestive of a vascular tumor. The resection of this mass was radical, and histological analysis and immunohistochemistry returned in favor of embryonic rhabdomyosarcoma. In similar cases recorded in the literature, the diagnosis may be first mistaken for that of a hemangioma, then confirmed by histology. This underlines the importance of a systematic anatomopathological examination of all tissues removed surgically.

Triple-A Syndrome in Morocco: Founder Effect, Age Estimation of the AAAS c.1331+1G>A Variant, and Implications for Genetic Diagnosis.

Introduction: Triple-A syndrome (Triple-A) is an autosomal recessive disorder characterized by alacrimia, achalasia, and adrenal insufficiency. Several variants on the AAAS gene have been described, and some variants are clustered in particular geographical areas, such as the c.1331+1G>A variant which is very frequent in North Africa. Here, we describe the genetic features of Triple-A in a series of unrelated families from Morocco. Methods: Screening for the AAAS c.1331+1G>A variant was performed by direct sequencing or by PCR-RFLP. Haplotype analysis using Single Tandem Repeat (STR) markers flanking AAAS gene was performed in order to evaluate the founder effect and estimate the age of the c.1331+1G>A variant. Results: Seven unrelated families with ten individuals clinically diagnosed with Triple-A were evaluated for sequence variations in the AAAS gene. The median age at diagnosis was 3 years, with a range between 2 and 11 years. Molecular analysis revealed that all patients were homozygous for the c.1331+1G>A variant. This variant was not found in 200 healthy controls, indicating that carriers are very rare in the general Moroccan population. Subsequently, STR marker analysis revealed a founder effect and that the most recent common ancestor of Triple-A patients in Morocco would have lived 125 years ago. Conclusion: This is the largest series of Triple-A in Morocco. The same AAAS c.1331+1G>A variant was found in all patients, suggesting a founder effect in Morocco which was subsequently confirmed by microsatellite marker analysis. Therefore, this variant should be systematically investigated to diagnose Triple-A in Morocco.

First report on chromosomal abnormalities in Eastern Morocco: Identification of a new case of a de novo partial trisomy 13q using single-nucleotide polymorphism array.

BACKGROUND: Chromosomal abnormalities are the main cause of birth defects, intellectual disability, and miscarriages. They contribute to significant human morbidity and infant mortality. Here we report for the first time the chromosomal abnormalities encountered in the population of Eastern Morocco. Furthermore, we describe a new case of a de novo partial trisomy 13q combined with a terminal deletion in an 11-day-old girl. METHODS: From November 2015 to March 2022, 195 patients from the BRO Biobank who were clinically suspected of having chromosomal abnormalities were referred to the cytogenetics laboratory of the Genetics Unit of the Faculty of Medicine and Pharmacy of Oujda for cytogenetic study. Karyotyping analysis was performed on peripheral blood samples using standard R banding techniques. To identify single-nucleotide polymorphism (SNP) and copy number variants (CNVs), Illumina SNP array was used. RESULTS: Among 195 studied cases, 32 (16.4 %) had abnormal karyotypes, of which 12 cases had numerical aberrations while 20 cases had structural aberrations. The most common numerical aberrations were Turner syndrome and Down syndrome followed by Edward, Patau, and Klinefelter syndromes. For structural aberrations, translocations were the most common, followed by derivative chromosomes, inversions, deletions, and an addition on chromosome 13 identified in an 11-day-old girl. To further characterize this addition, SNP array was carried out and revealed a 58.8-Mb duplication in region 13q14.3q34 associated with a 1-Mb deletion in region 13q34. Follow-up parental chromosomes analysis showed normal karyotypes for the parents, confirming that this partial trisomy 13q was de novo. Comparison of the phenotype associated with this novel duplication on chromosome 13q with those previously reported confirmed the considerable variability in the phenotype of the patients with partial trisomy 13q. CONCLUSION: This study provided the first report on chromosomal abnormalities in Eastern Morocco and it enriched the phenotype spectrum of partial trisomy 13q and further confirmed the genotype-phenotype correlations. Furthermore, these findings justify the need to set up microarray comparative genomic hybridization techniques in Morocco for better genetic diagnosis.

Bean Syndrome in a Child Treated with Sirolimus: About a Case.

Bean syndrome (BS) or blue rubber bleb nevus syndrome is a rare clinical entity characterized by venous malformations mainly in the skin and digestive tract, whose hemorrhagic complications can be life threatening. We report a case of Bean syndrome in a 3-year-old child of nonconsanguineous parents, in whom the diagnosis of miliary hemangiomatosis was initially made in view of a huge mass on the left thigh, taking the knee, and then the progressive appearance of a skin disorder with bluish swellings of variable sizes spread over the whole body. The patient was put on beta-blockers but without improvement. The evolution was marked by an increase in the volume of the thigh mass. Ultrasound exploration coupled with Doppler imaging revealed the presence of angiomas in the thigh, requiring emergency surgery following a large hemorrhage. The patient underwent sclerotherapy. At the age of 18 months, the child returned with severe anemia and melena. The abdominal CT scan showed gallbladder intussusception secondary to an angioma requiring intestinal resection for hemostasis. At the age of three years, the angiomas worsened with an increase in volume, particularly on the face. The association of the cutaneous and digestive involvement of these venous malformations made us rectify the diagnosis. The patient was put on sirolimus (rapamycin), 2 mg/m2, with good evolution with a delay of 18 months; the patient presents no more episodes of bleeding with regression of the size of cutaneous angiomas. This observation underlines that BS is difficult to diagnose because of its low frequency, that sirolimus was effective and well tolerated in our patient, and that it can be suggested as a good and safe therapeutic option.

Acute pancreatitis following L-asparaginase in acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is the most frequent malignancy in children,representing 25-30% of all childhood malignancies. Although treatment outcome has improved owing to advances in chemotherapy, there is still a group of patients who experience severe adverse events. L-Asparaginase is an effective antineoplastic agent used in chemotherapy of ALL. Despite its indisputable indication, it can cause various adverse effects, including acute pancreatitis (AP). Recently, an increase in the number of pediatric AP cases following L-Asparaginase in Acute Lymphoblastic Leukemia been reported. We presented a case of acute pancreatitis in children with ALL induced by administration of L-ASPA preparations.

Molecular heterogeneity of ß-thalassemia variants in the Eastern region of Morocco.

BACKGROUND: ß-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 ß-globin chain synthesis. The severity of the disease depends on the nature of the variants affecting the ß-globin gene (HBB), and each ethnic group has its own mutation spectrum. Hereby, we present, for the first time, the molecular profile of ß-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 ß-thalassemia major and 20 with ß-thalassemia minor. To detect mutations of the ß-globin gene, we have used RFLP-PCR and Sanger sequencing. RESULTS: Nine known ß-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 ß-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 ß-thalassemia in the Eastern region of Morocco. It shows the high molecular heterogeneity of ß-thalassemia in our country. Therefore, these results can be valuable for the implementation of carrier screening, genetic counseling, and prenatal diagnosis programs.

Atypical Kawasaki Disease in an Adolescent with Multivisceral Involvement.

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.
