Parents often have misperceptions about childhood fever, and little information is available about the home management of feverish children in Morocco. In this study of the perceptions, knowledge and practices of families regarding children's fever, the parents of 264 febrile children aged 0-16 years were interviewed in a paediatric emergency department in Rabat in 2011. Only 3.5% of parents knew the correct temperature definition for fever, 54.4% determined their children's fever using a thermometer, and the preferred site was rectal. Most of them (96.8%) considered that fever was a very serious condition, which could lead to side-effects such as brain damage (28.9%), seizures (18.8%) paralysis (19.5%), dyspnoea (14.8%) and coma (14.8%). Paracetamol was used by 85.9% and traditional treatments by 45.1%. Knowledge about the correct definition of fever was significantly associated with parents' profession, educational level and receipt of previous information and advice from health professionals. (14,8 %). Le paracétamol a été utilisé par 85,9 % des parents et les traitements traditionnels par 45,1 %. La connaissance de la définition exacte de la fièvre était significativement associée à la profession des parents, à leur niveau d'études et à la prise de conseils et d'informations préalable auprès des professionnels de santé.

Introduction and importance The primary intestinal lymphangiectasia is a rare exudative enteropathy of unknown etiology that affects the lymphatic system. It causes lymphedema and malabsorption syndrome by the escape of the lymph and its elements into the intestinal lumen. Case presentation A female patient, diagnosed at the age of 11 with Waldmann's disease, has initially manifested chronic diarrhea with a stature-ponderal delay at the age of 6 months old; she was treated for a long time as celiac disease patient. Edematous syndrome, chronic diarrhea, staturo-ponderal delay and asymmetric lymphedema of the upper limb are the main clinical symptoms in this case. In addition, the exclusion of secondary intestinal lymphangiectasia was important for the diagnosis. Before and during her follow-up, the patient presented two complications of the disease: warts and osteomalacia. The patient did not respond to treatment with the low-fat diet; therefore, the need to add treatment with octreotide was necessary, which has given quite pleasant results. Octreotide was the therapeutic choice to treat the patient as she was resistant to the appropriate regimen with clinical improvement; nevertheless, certain biological elements of lymphatic leakage persisted. Discussion Waldmann's disease is rare. It can be responsible, besides the typical signs, for complications including warts and osteomalacia. The histopathological study of intestinal biopsies may be normal if lymphangiectasias are localized. The treatment is based on a nutritional diet associated with octreotide. During the patient's follow-up, the evolution after almost two years of the introduction of octreotide compared to the diet alone showed improved outcomes. Conclusion The treatment of Waldmann's disease is based on an adapted diet and octreotide. This case highlighted the importance of the long term follow-up in this disease.

Background. Biobanks are highly organized infrastructures that allow the storage of human biological specimens associated with donors’ personal and clinical data. These infrastructures play a key role in the development of translational medical research. In this context, we launched, in November 2015, the first biobank in Morocco (BRO Biobank) in order to promote biomedical research and provide opportunities to include Moroccan and North African ethnic groups in international biomedical studies. Here, we present the setup and the sample characteristics of BRO Biobank. Methods. Patients were recruited at several departments of two major health-care centers in the city of Oujda. Healthy donors were enrolled during blood donation campaigns all over Eastern Morocco. From each participant, personal, clinical, and biomedical data were collected, and several biospecimens were stored. Standard operating procedures have been established in accordance with international guidelines on human biobanks. Results. Between November 2015 and July 2020, 2446 participants were recruited into the BRO Biobank, of whom 2013 were healthy donors, and 433 were patients. For healthy donors, the median age was 35 years with a range between 18 and 65 years and the consanguinity rate was 28.96%. For patients, the median age was 11 years with a range between 1 day and 83 years. Among these patients, 55% had rare diseases (hemoglobinopathies, intellectual disabilities, disorders of sex differentiation, myopathies, etc.), 13% had lung cancer, 4% suffered from hematological neoplasms, 3% were from the kidney transplantation project, and 25% had unknown diagnoses. The BRO Biobank has collected 5092 biospecimens, including blood, white blood cells, plasma, serum, urine, frozen tissue, FFPE tissue, and nucleic acids. A sample quality control has been implemented and suggested that samples of the BRO Biobank are of high quality and therefore suitable for high-throughput nucleic acid analysis. Conclusions. The BRO Biobank is the largest sample collection in Morocco, and it is ready to provide samples to national and international research projects. Therefore, the BRO Biobank is a valuable resource for advancing translational medical research.

Pour les pays en voie de développement, l'hémophilie continue d’être une maladie de conséquence médicale et sociale désastreuse. Le but de ce travail est d'analyser le suivi d'une cohorte de patients hémophiles. Patients et méthodes: étude prospective étalée sur deux années et menée au centre référent d'hémophilie dans la région de l'orient du Maroc. Ont été inclus tous les patients présentant une hémophilie confirmée et âgé de moins de 18 ans. Résultats: sur 16 hémophiles, Quinze patients présentait une hémophilie A, l’âge moyen des patients était de 6,18 ans, la forme sévère, représentait 20,7%, la forme modérée: 33,3% et la forme mineure: 40%. Les circonstances de découverte étaient post circoncisionnelle chez 53,3% des patients, 20,7% post traumatique, 20% à l’âge de la marche; la durée d’évolution variait entre 2 mois et 10 ans. L'hémarthrose a été décrite au niveau des genoux, coudes et chevilles, avec une moyenne allant de 2 à 5 fois par an; l'arthropathie a été remarquée dans 33,3%. Le bilan immunologique a révélé des facteurs circulant inhibant chez deux patients. Le traitement était à base d'antalgiques, de plasma frais congelé. L'administration de facteurs VIII recombinés a été instaurée chez 40,6% des patients (plus de 90% des formes modérées et graves), grâce au programme national de prise en charge des hémophiles. Le décès était noté dans un seul cas lié à une hémorragie cérébrale. Conclusion: Nous insistons sur l'intérêt du programme national de prise en charge des hémophiles dernièrement instauré qui pourrait améliorer les conditions de vie de ces enfants.

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.

Introduction: The aorto-pulmonary window is a rare congenital heart disease. It is a defect between the ascending aorta and the trunk of the pulmonary artery upstream of the pulmonary bifurcation. Once the diagnosis is made, surgery must be performed quickly to avoid progression to pulmonary arteriolitis. We report the case of a 4-month-old infant in whom we made the diagnosis of aorto-pulmonary window type I. He was able to benefit from an open heart surgery at FES with an excellent result after closing the window. Conclusion: The aorto-pulmonary window is a rare congenital heart defect, the diagnosis of which must be made as early as possible in order to avoid the progression to pulmonary hypetension and heart failure.
