Data on acute kidney injury (AKI) in critical forms of coronavirus disease 2019 (COVID-19) are scarce. We aimed to assess the incidence, risk factors and prognostic impact of AKI complicating critical forms of COVID-19. Methods

Commonly, PB often complicates the course of cardiac or respiratory disorders. The occurrence of PB before manifestation of the underlying respiratory disease is unusual. We report on the case of a boy, aged three years and eight months, free from underlying pulmonary disease, who presented with extensive atelectasis of the left lung during an acute respiratory tract infection. Bronchoscopy revealed the obstruction of the left tracheobronchial tree with large purulent casts. After bronchoscopic removal of the casts, the boy became asymptomatic. Initial aetiological investigations were negative. Two years later, the patient developed an asthma.

Diagnosis of TS remain challenging since it can be confused with common diarrheal diseases, especially in non-endemic areas. We report a Tunisian case of latent TS. A 58-year-old male with a history of chronic watery diarrhea, was admitted to the intensive care unit for confusion which was related to severe metabolic acidosis. Despite the neurological improvement after hydro-electrolytic resuscitation and acid-base disorders correction, the patient continued to have three to five loose stools daily. A nutritional assessment showed a malabsorption syndrome: iron, Vitamin B12 and folate deficiencies; normochromic normocytic anemia and hypoalbuminemia. Gastrointestinal endoscopy showed duodenal villous atrophy and biopsy confirmed subtotal villous atrophy with increased intraepithelial lymphocytosis and a thickened hyalonalized sub-epi...

Patients et methodes: Nous avons repertorie 188 NNMC compares a une population temoin de 187 NN de femmes mariees ayant accouche lors de la meme periode Resultats: L'âge moyen etant de 22,4 ans versus 28,4 ans pour les meres temoins (MT), avec une origine rurale dans 45,4% (versus 27,3%). Les grossesses non suivies cliniquement dans 70,6% des cas. L'hospitalisation des NNMC etait statistiquement plus longue (38,4% vs 13,2%) avec des causes representees par l'infection materno-fœtale (14,4%), la detresse respiratoire (11,7%), la prematurite (9,6%) et le retard de croissance intra-uterin (2,1%).Le taux de mortalite etait de 5,3%. Les nouveau-nes n'ont ete pris en charge par les meres celibataires que dans 62,2% des cas. Conclusion: La grossesse illegitime non desiree, est souvent non sui...

Patients et methodes: cette etude retrospective a concerne 30 cas colliges au service de pediatrie de Bizerte et par l'Union Tunisienne d'Aide aux Insuffisants Mentaux. Resultats: l'âge moyen etait de 9,9 ans et le sex ratio de 2,75. L'âge moyen des meres au moment de l'accouchement etait de 35 ans, superieur a 35 ans dans 34 pour cent des cas. 70 pour cent des grossesses ont ete suivies sans aucun diagnostic prenatal. L'etude genetique a montre une predominance de la trisomie 21 libre (92,4 pour cent) et 7,6 pour cent par translocation. Nous avons observe des anomalies de l'immunite humorale et une frequence elevee des anticorps antithyroidiens (63% des cas), anti-gliadine et anti endomysium (30 pour cent des cas). Conclusion: Ces resultats nous incitent a faire un diagnostic precoce du syndrome et des anomali...

A transversal retrospective study was carried out in Bizerta from 1990 to 2003. The witness group was constitued by women whose gonna delivery at the same period with p < 0.05. Throughout this study, we have found that single mothers with a mean age of 24 years, are younger than married mothers and has a rural origin and primiparous status. Pregnancy was not followed-up in 70.6% vs. 1.6% and maternal serology was done in 17% vs. 96.8%. 38.4% of new-borns of single mothers were hospitalised (vs. 13.2% in the group witness) for materno-foetal infection (14.4%), respiratory distress syndrome (11.7%), prematurity (9.6%) and intra-uterine growth delay (2.1%). The mortality rate in newborns of single mothers was 5.3%. Illegitimate pregnancy is not well followed-up, worst to live and comport a risk for the health and mental in mothers and newborns.

But: Rapporter une nouvelle observation. Observation :On rapporte le cas d'un garcon âge de 6 ans aux antecedents de canal arteriel persistant opere a l'âge de 11 mois, admis pour exploration d'une pneumopathie gauche. La radiographie thoracique a montre une opacite non systematisee de la partie mediane du champ pulmonaire gauche du lobe inferieur gauche. L'echographie thoracique qui a mis en evidence une masse hyperechogene pleurale absorbant fortement les echos et s'accompagnant d'un cone d'ombre posterieure mesurant 5 cm de grand axe, entouree d'une condensation parenchymateuse evoquant un textilome. Le scanner thoracique a montre une condensation parenchymateuse posterieure, centree par une formation hyperdense. La plevre en regard est ep...

Thorax x ray showed a non systematized operety in middle fueld of cefts lung. Ultrasonography demonstrated a plural hyperchonic.

CT scan showed a condensation of lung tissue hyperdense tumor in its center. Pleuval membrane because thick the foreign body was removed significantly and a pleural decortication was performed post operative course was uneventful CONCLUSION pleural textiloma, is rare but it still severe complications with its li...

We report 79 cases of congenital heart defects treated which are followed up in the department of general paediatrics in the University Hospital of Bizerta during 9 years. The informations concerning the patients is taking to a data file. The newborns included had a congenital heart disease suspected clinicly or confirmed by a cardiac echography. The sex-ratio was 0,79 with a mean of weight birth of 3075 g. The prematurity reaches 20.1%. The consanguinity was 30.5%. Congenital heart defects were detected the first week of life in 47% with a murmur on 77.6%, cyanosis on 70%, dyspnea on 89%. The annual incidence was evaluated 2.5% per hundred. One hundred and Twelve heart defects were diagnosed. The medical treatment was indicated on 46.3% and the surgery on 22.5%. Mortality was on 23.8%. Congenital heart disease particularly in...
