Tuberculous otomastoiditis complicated by thrombosis of the sigmoid sinus in an infant.

Otomastoiditis is a rare and exceptional complication of tuberculosis; its pathogenesis has been debated since its recognition as a distinct condition. The evolution and prognosis in general are modified after the end of antituberculosis treatment. In our observation, we report the case of an infant with tuberculous otomastoiditis complicated by sigmoid sinus thrombosis.

Digestive manifestations of Covid-19 in children: a retrospective study.

Background: The world is currently facing a pandemic due to a new species of the Coronaviridae family called SARS-CoV-2, discovered in the city of Wuhan in China in December 2019. The WHO has named the resulting disease COVID-19 (Coronavirus Disease 2019). It has been a global health problem due to its major socio-economic damage. The aim of this study was to show the prevalence of gastrointestinal and hepatic manifestations in symptomatic children with COVID-19. Methods: We performed a retrospective study, including 36 symptomatic children infected by SARS-CoV-2 hospitalized at the mother and child hospital of university hospital of Mohammed VI, Marrakech in Morocco, over a period of 7 months. Clinical and biological manifestations of the digestive system were evaluated for all patients. Results: The digestive symptomatology came in second place after the respiratory manifestations. 14 patients (38.89 % of symptomatic patients) in our study had digestive symptoms on admission: 12 (33.33%) presented with diarrhea, 4 (11.11%) had abdominal pain and only one child (2.78%) had vomiting. Aspartate aminotransferase (AST) was elevated in one patient, while alanine transaminase (ALT) was elevated in 6 patients. The prothrombin level was normal in all patients. All patients were discharged with good general condition without morbidity and mortality. Conclusion: This study concludes with the high prevalence of digestive manifestations of COVID-19 in symptomatic children. There were no severe clinical or biological abnormalities in our study. Digestive manifestations during COVID-19 in children are frequent, which requires the awareness of health professionals.

Changes in the Epidemiology of Respiratory Pathogens in Children during the COVID-19 Pandemic.

Since the outbreak of the COVID-19 pandemic, a significant decrease in non-COVID-19 respiratory illnesses were observed, suggesting that the implementation of measures against COVID-19 affected the transmission of other respiratory pathogens. The aim of this study was to highlight the changes in the epidemiology of respiratory pathogens in children during the COVID-19 pandemic. All children with Severe Acute respiratory illness admitted to the pediatric departments between January 2018 and December 2021 with negative COVID-19 PCR, were enrolled. The detection of respiratory pathogens was made by the Film Array Respiratory Panel. A total of 902 respiratory specimens were tested. A significantly lower positivity rate during the COVID-19 period was found (p = 0.006), especially in infants under 6 months (p = 0.008). There was a substantial absence of detection of Respiratory Syncytial Virus and Influenza A during the winter season following the outbreak of the pandemic (p < 0.05; p = 0.002 respectively). An inter-seasonal resurgence of Respiratory Syncytial Virus was noted. Human Rhinovirus was detected throughout the year, and more prevalent in winter during COVID-19 (p = 0.0002). These changes could be explained by the impact of the implementation of preventive measures related to the COVID-19 pandemic on the transmission of respiratory pathogens in children.

Varicella Zoster Virus Meningitis with Absence of Rash in an Immunocompetent Child.

Only a few cases in the literature have ever reported the reactivation of the varicella zoster virus (VZV) in children especially in the case of immunocompetent patients. It is an uncommon situation that may lead to several neurological complications. We report varicella zoster virus (VZV) meningitis in a 14-year-old healthy boy with no antecedent of rash. On his cerebrospinal fluid (CSF) examination, VZV DNA was detected. The rapid HIV test was negative. The treatment using acyclovir (20 mg/kg/8h) was effective, and the child's clinical condition rapidly improved.

Idiopathic Spinal Epidural Lipomatosis: Unusual Presentation and Difficult Management.

Epidural lipomatosis (EL) is a pathology characterized by abnormal accumulation of unencapsulated fat in the epidural space. Although rare, it is a possible cause of lumbosciatica or narrow lumbar canal in adults. It is often associated with favorable factors such as prolonged corticosteroid therapy or obesity. We report an observation of an 18-month-old child who presented with walking delay without other abnormalities, and the radiological exploration confirmed the lumbar epidural lipomatosis. The management was mainly symptomatic, based on motor physiotherapy with additional management in neurosurgery. Various etiologies can cause this disease, remain rare in pediatrics, and the idiopathic form is predominant in children.

Hydropneumothorax Revealing a Pneumoblastoma in Children.

Pneumoblastoma is a rare primary childhood tumor. We report the observation of an infant aged 2 years and 8 months who presented with dry cough and dyspnea. The physical examination found mixed pleural effusion syndrome on the right. The chest X-ray revealed a right pneumothorax. Biology has shown leukocytosis at 16,000/mm3. The CT scan revealed parenchymal air cystic lesions affecting the outer segment of the middle lobe mimicking a pulmonary malformation. Thoracic drainage brought back 100 ml of the fluid. Two months later, when a pyopneumothorax appeared, a medium lobectomy was performed. Pathological study specimen showed a high-grade type II pneumoblastoma The extension assessment identified a secondary hepatic location. Chemotherapy has been indicated. This observation illustrates the diagnosis challenge of pneumoblastoma in children.

Laboratory abnormalities in children with novel Coronavirus Disease 2019.

The novel Coronavirus disease 2019 continues to be a worldwide pandemic. Yet, little is still known about the biological features of this emergent infection in children. In this prospective study, we collected 68 children infected with SARS-COV-2 from March 2020 to May 2020, in Marrakesh, Morocco. No severe cases were observed in this cohort, and 66% of the patients were asymptomatic. The main laboratory abnormalities were hematological, as we found Leucopoenia in 4.4% of the cases, hyperleukocytosis in 1.6%. Neutropenia was found in 5 patients (7%) and only 2 cases (3%) had Lymphopenia. The inflammation and coagulation biomarkers were normal in the majority of the cases, as for liver and kidney function. Lactate dehydrogenase (LDH) serum levels were elevated in 8 cases (11.67%). The COVID-19 in children seems to have mild course and better outcome than in adults, which impacts the laboratory findings in this category. More studies must be conducted to learn more about the laboratory abnormalities in pediatric COVID-19.

Toxic shock syndrome and pyomyositis: about an unusual case.

Pyomyositis is a pyogenic infection of skeletal muscle with abscess formation. It is a rare disease with nonspecific symptoms which requires a rapid diagnosis and treatment. Magnetic resonance imaging is considered the gold standard for early diagnosis and to rule out other etiologies. This article reports an atypical presentation of pyomyositis revealed by a toxic staphylococcal shock syndrome in an 8-year-old boy.

[An unusual case of cardiomyopathy showing carnitine palmitoyltransferase deficiency]. / Une cardiomyopathie révélant un déficit en carnitine palmitoyltransférase I: à propos d'un cas inhabituel.

Carnitine palmitoyltransferase deficiencies (CPD) are rare and caused by a defect in fatty acid oxidation. We here report the case of a 10-year-old patient with no particular previous history presenting with acute dyspnea associated with productive cough, fever and impaired general condition. The patient was polypneic with tachycardia, mitral systolic murmur and no sign of heart failure. Chest x-ray showed cardiomegaly and echocardiography revealed hypokinetic dilated cardiomyopathy. Carnitine palmitoyltransferase deficiency was diagnosed. Management was based on treatment for heart disease and strict hypopidic and hyperglucidic diet. Three months later, the patient presented with decompensated heart failure due to infection caused by antibiotic-resistant Aeromonas caviae identified in blood culture. CPD should be suspected in patients with dilated cardiomyopathy. This would enable early management which influences prognosis.

Case Report of Central Precocious Puberty in a Female: Role of Environmental Pollutants?

A 5-year-old girl was brought to Department of Pediatric Endocrinology and Diabetes for premature breast development since 4 months. Her medical antecedents and family history were uneventful. From investigations she was diagnosed as a case of central precocious puberty. Identification of pesticides in farms surrounding their house indicates that this early stimulation of the hypothalamic-pituitary-gonadal axis was linked to the estrogen-like activity of endocrine-disrupting compounds.

Usefulness of urinary glycosaminoglycans assay for a mucopolysaccharidosis-specific screening.

BACKGROUND: Mucopolysaccharidoses (MPS), a group of inherited metabolic disorders characterized by the accumulation of glycosaminoglycans, can be diagnosed early through newborn screening programs. Establishing newborn screening in Morocco is a challenging task for multiple economic and social reasons. Screening in a Moroccan population using 1,9-dimethylmethylene blue urinary glycosaminoglycan (GAG) assays may allow for an earlier diagnosis of MPS. We studied the feasibility of implementing screening in Moroccan children as an alternative to national newborn screening. We determined the reference ranges for GAGs in the Moroccan population, their stability during transport, the effectiveness of this test as a screening procedure for MPS in patients, and its use as a screening test for MPS in the Imssouane region, where the rate of consanguineous marriage is 38%. METHODS: Using dimethylmethylene blue assays, urine samples of 47 MPS patients were analyzed, together with urine samples from healthy controls (n = 368, age ranging from 1 month to 25 years), and from Imssouane region children (n = 350, age ranging from 6 months to 24 month). Precision, linearity, recovery, limits, and stability were tested. RESULTS: Urinary GAGs reference values are age and ethnicity dependent. The validation parameters established displayed great precision and accuracy leading to recoveries according to internationally accepted values for bioanalytical methods. Urinary GAGs were stable for a maximum of 7 weeks at 40 °C. Screening of Imssouane children resulted in the detection of a 6-month-old child, diagnosed with MPS I. CONCLUSIONS: Our results demonstrate the usefulness of quantifying glycosaminoglycans for early screening of MPS.

[Bird fancier's disease in a child: about a rare and unusual case]. / La maladie du poumon des éleveurs d´oiseaux chez un enfant: à propos d´un cas rare et inhabituel.

Bird fancier's disease falls within the spectrum of hypersensitivity pneumonitis secondary to immuno-allergic reaction to avian antigens. This occurs only rarely in children. It is found in two-thirds of patients with hypersensitivity pneumonitis. Diagnosis is not so easy. It is based on a body of clinical evidence. We here report the peculiar case of a 7-year-old girl with a family history of atopic disease initially treated as asthma based on the presence of wheezing and dyspnea and cough without improvement. The patient had worsening of symptoms such as dyspnea at rest complicated by cyanosis in respiratory distress. All of this took place in a context of alteration of general state. Clinical examination showed growth retardation, perioral cyanosis with digital hippocratism. Lung auscultation revealed bilateral crackling sounds. Chest X-ray objectified bilateral interstitial syndrome. Chest computed tomography (CT) scan showed diffuse ground-glass opacities. Laboratory tests revealed hypereosinophilia with hyper-IgE and excluded tuberculosis, cystic fibrosis, immune deficiency. In a second stage interview contact with birds was reported. Serological tests for bird fancier's disease were positive. The patient received inhaled corticosteroids associated with avoidance of exposure to birds. After a follow-up of 2 months, outcome was favorable. Given that the signs of bird fancier's disease are non-specific, this should be suspected in patients with respiratory symptoms associated with exposure to avian antigens.

An Unusual Neurological Form of Acute Intussusception in an Infant: Late Diagnosis and Management.

Acute intussusception is one of the most common causes of intestinal obstruction in infants and small children and involves the invagination of one bowel segment into another. The clinical signs can be deceptively misleading when there is only one symptom or when an unusual symptom is in the foreground, especially in infants less than 1-year-old. We report a case of an infant with an acute intussusception where the neurological symptoms are predominant. The neurological form is the expression of major vascular narrowing of the collar of the intestinal intussusception; this form is rare and misleading and can be responsible for a delayed diagnosis.

[Cerebral venous thrombosis in children: about a series of 12 cases]. / Thrombose veineuse cérébrale de l'enfant: à propos d'une série de 12 cas.

Cerebral venous thrombosis (CVT) is rare in children. Its clinical features and its cause vary. Prognosis is dreadful due to the risk of death and neurosensory sequelae. This study aims to examine the clinical, radiological and etiological profile of CVTs in children and to evaluate the role of antithrombotic treatment. We conducted a retrospective study in the Department of Paediatrics and Paediatric Resuscitation at the Center Hospital University Mohammad VI (CHU) in Marrakech, Morocco, over a period of nine years and ten months (January 2008-October 2018). We collected data from the medical records of all patients aged between 1 months and 15 years with CVT confirmed by imaging. We listed 12 cases of CVT. The average age of patients was 6.4 years. Sex ratio was 1.4. Acute onset occurred in 7 cases. The main clinical features of CVT included seizures (7 cases), focal neurologic signs (7 cases) and signs of intracranial hypertension (IH) (6 cases). CT scan and/or magnetic resonance imaging (MRI) revealed an involvement of the superficial venous network in 8 cases and extended venous involvement in 3 cases. In six cases CVT was caused by an infection, with a case of dehydration, two cases of systemic disease and a case of homocystinuria. However, the cause of the disease was unknown in two patients. Seven children were treated with antithrombotic therapy with good clinico-radiological outcome in 5 cases. Two children died and 3 others had neurological sequelae. In children, CVTs are characterized by a vast variety of clinical features and causes. The effect of anticoagulant therapy was demonstrated despite the absence of a standardized therapeutic protocol.

[Acceptability of human papilloma virus vaccine: parent survey]. / Acceptabilité du vaccin antivirus du papillome humain: enquête auprès des parents.

This study aims to evaluate the extent of human papilloma virus vaccine awareness among parents of girls in vaccine age group, their acceptability of the vaccine and factors associated with refusal. We conducted a survey among parents of girls aged 8-15 years, followed-up for several diseases in the Department of Pediatrics at the University Hospital Mohamed VI in Marrakech, Morocco, on parents' profile, their awareness of cancer of the cervix, HPV and HPV vaccine, the acceptance of HPV vaccine for their daughters and the arguments related to refusal. Ninety six questionnaires were included in the analysis. Cancer of the cervix was considered frequent for 58% of parents. Only 5% of parents knew about HPV vaccine. Media were the source of information in all cases. Nobody had no idea about the cost of the vaccine and its tolerance. No girl was vaccinated against HPV. Sixty-three per cent of parents want their daughters to be vaccinated, this rate increased by 82% after awareness. Thirteen per cent of the parents were hesitant while 24% refused to vaccinate their daughters mainly due to side effects (51%). Parents refusing vaccine were predominantly males with medium socioeconomic status and cultural level and were unaware of the virus and the vaccine in 91% of cases. This study highlights the reasons for parents' reluctance towards HPV vaccine in order to optimize strategies for effective communication with parents.
