RESUMO
OBJECTIVES: Graves' disease (GD) is a rare auto-immune disorder in pediatric population. The association between GD and thymic hyperplasia was rarely reported in children. Diagnosis and management of GD are challenging in children. CASE PRESENTATION: This report presents the case of a 5-year-old girl with a personal history of asthma and congenital bilateral isolated clinical anophthalmia who presented with acute congestive heart failure, sinus tachycardia and atypical signs of orbitopathy with edema and erythema of the lower right eyelid and excessive tearing. The diagnosis of GD was based on detecting a suppression of serum TSH level and the presence of high titers of TRAbs. Relapse occurred after 10 months of antithyroid drugs with chief complaints of palpitations, dyspnea and dysphagia. Computed tomography showed heterogeneous anterior mediastinal mass with no invasion into the surrounding tissue. The marked shrinkage of the mass after radioiodine therapy supported the diagnosis of thymic hyperplasia associated with GD. CONCLUSIONS: The presence of clinical anophthalmia may be a confusing factor for the diagnosis of Graves' ophthalmopathy. Recognition of the association between GD and thymic hyperplasia would avoid invasive diagnostic procedures and unnecessary surgical resection. Radioiodine therapy may be used in young children with repeated relapses of GD.

Due to low susceptibility of coronavirus disease of 2019 (COVID-19) in children, limited studies are available regarding COVID-19 in the pediatric population in Tunisia. The current study evaluated the incidence, clinical characteristics, and outcomes of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection among children hospitalized at Béchir Hamza Children's Hospital. A retrospective cohort analysis was conducted using the hospital database between March 2020 and February 2022 with children aged ≤15 years with SARS-CoV-2 infection (confirmed by RT-PCR). A total of 327 COVID-19 hospitalized patients with a mean age of 3.3 years were included; the majority were male. Neurological disease (20%) was the most common comorbidity, while fever (95.3%) followed by cough (43.7%) and dyspnea (39.6%) were the most frequent symptoms reported. Severe disease with oxygen requirement occurred in 30% of the patients; 13% were admitted in the Intensive Care Unit. The overall incidence rate of COVID-19 hospitalization (in Tunis governorates) was 77.02 per 100,000 while the inpatient case fatality rate was 5% in the study population. The most prevalent circulating variant during our study period was Delta (48.8%), followed by Omicron (26%). More than 45% of the study population were <6 months and one-fourth (n = 25, 26.5%) had at least one comorbidity. Thus, the study findings highlight the high disease burden of COVID-19 in infants.

INTRODUCTION: Clinical reasoning (CR) is a core skill taught by medical schools. Clinical reasoning learning sessions (CRL) during hospital internship of externals in pediatrics was recently introduced in Faculty of Medicine of Tunis. AIM: To compare a case based self-directed learning (CBSDL) tool with CRL sessions in two groups of the students assigned to pediatric internship. METHODS: We conducted a randomized trial with draw of two groups: CRL group (students who attended the CRL session) and SDL group (students who received the CBSDL tool). Main judgment criterion was the final score obtained by the student at the test of sequential management problem (SMP). A docimological analysis of SMP test was performed. RESULTS: The mean final score in CRL group and SDL group was 12.03±1.44 and 14.05±1.64, respectively (p <0.001). The scores obtained at the different steps of SMP test were significantly higher in SDL group. The difficulty p and discrimination D indices of the SPM test were 0.65 and 0.21, respectively. The agreement between the two correctors was very good since the intra-class correlation coefficient was 0.977. We analyzed the reliability of the test by measuring Cronbach's α coefficient which was 0.955. CONCLUSION: CBSDL tool has allowed students to learn hypothetico-deductive reasoning. However, this tool must be supplemented by direct supervision at hospital internship to support CR.

Congenital Methemoglobinemia is a rare condition that may mimic congenital heart diseases. There are two types of congenital Methemoglobinemia. The type I is usually benign. The enzyme deficiency is limited to red blood cells. Clinically, the patient presents cyanosis without neurological disorders. Whereas, in type II, cyanosis is associated with severe neurological impairment.
RESUMO
BACKGROUND: Hypothyroidism with impairment of renal function and raised creatinine phosphokinase (CPK) is described in adults and children with acquired hypothyroidism, but not in congenital hypothyroidism. CASE PRESENTATION: A male infant born at term weighing 3390 g was seen aged 2 months with prolonged jaundice. Examination showed somnolence, umbilical hernia, enlarged fontanelles and lower limb edema; length 55 cm (-1.5 SD), weight 5.4 kg (-0.13 SD). Biochemistry showed fT4 < 1 pmol/L, TSH = 1044.36 µUI/mL, creatinine 77 µmol/L(normal <35 µmol/L), estimated glomerular filtration rate (GFR) 26 ml/min/1.73 m2, CPK 3952.5 IU/L (normal<400 IU/L). Ultrasound showed no thyroid tissue in the neck. In view of the renal impairment, peritoneal dialysis was initially contemplated but postponed and the child received levothyroxine 10 µg/kg/day. Two months later thyroid function tests, CPK and renal function had all normalized with creatinine 19 µmol/L and GFR 116 ml/min/1.73m2. DISCUSSION: Reversible renal impairment is attributable to severe congenital hypothyroidism causing decreased myocardial contractility and cardiac output and to a direct effect on the kidneys. Thyroid function should be checked in infants with renal impairment of unknown cause. Cautious fluid management is indicated in hypothyroid infants. Hypothyroidism may also be associated with elevated serum CPK levels but resolves with thyroxin therapy.
