RESUMEN

Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome characterized by insulin-like growth factor-2 (IGF-2) release, often associated with diverse tumor types. Gastrointestinal stromal tumors (GISTs), sarcomatous lesions of the gastrointestinal tract, are rarely associated with NICTH. We present a unique case of a 58-year-old patient diagnosed with a GIST exhibiting recurrent hypoglycemia suggestive of NICTH. Despite normal IGF-2 levels, the IGF-2/IGF-1 ratio supported the NICTH diagnosis, which was confirmed histologically. Imaging revealed a large intraperitoneal mass. Hypoglycemia was managed with high-dose dextrose and hydrocortisone. Treatment with the tyrosine kinase inhibitor, imatinib, was initiated. Surprisingly, imatinib not only reduced the tumor size but also improved hypoglycemia. The study highlights the complexities in managing NICTH and its underlying causes. Current diagnostic limitations, treatment modalities, and unexpected therapeutic responses challenge standard approaches. This emphasizes the need for personalized oncological strategies.

RESUMEN

INTRODUCTION: Type 1 diabetes mellitus (T1DM) is a health problem that can be difficult for young people to accept. The aim of this study is to determine the prevalence and characteristics of school failure in children with T1DM and to identify the associated factors. MATERIAL AND METHODS: This is a retrospective study conducted in the endocrinology department of the Farhat Hached Hospital in Sousse, regarding T1DM patients, by analysing their school and career paths according to their clinicobiological and social data. School failure was defined in our study by the presence of at least one year's repetition and/or exclusion from school. RESULTS: Our study included 70 patients. School failure was recorded in 71.4% of cases. School drop-out was observed in 47.1% of patients. The reasons for school drop-out were iterative hospitalizations in 31.4% of cases and glycaemic instability with hyper/hypoglycaemic fluctuations in 17.1%. Multivariate analysis showed that the risk factors significantly associated with school failure were, respectively, number of hospitalizations for ketosis ≥ 5 (p = 0.037) and higher mean HbA1c at the last consultations (p = 0.001). Use of functional insulin therapy (p = 0.031) and use of insulin analogue (p = 0.004) were significantly protective factors. CONCLUSIONS: The risk of school failure in T1DM is real and should not be underestimated. Socioeconomic factors such as lack of financial resources, limited family support, and an unfavourable social environment can contribute to school avoidance.

RESUMEN

Background Some studies suggest that the SARS-CoV-2 pandemic has contributed to diverting attention from other community-acquired infections (CAIs), leading to an increase in their incidence and severity. Our study aimed to describe and compare clinical features of CAI before and during the pandemic as a factor precipitating diabetes ketoacidosis (DKA). Methodology We included 250 patients who presented with DKA due to CAIs, other than SARS-CoV-2, divided into two distinct groups: 100 patients (G1) who consulted two years before the pandemic, and 150 patients (G2) who consulted during the SARS-CoV-2 pandemic. Cases in both groups were matched for age and type and duration of diabetes. Primary outcomes were a longer diagnosis delay and more severe DKA in G2 during the pandemic. Secondary outcomes included blood test results, duration of ketosis, duration of antibiotic therapy, and diabetes treatment. Results The diagnosis and treatment delays were longer for patients seeking medical care during the pandemic (p < 0.001). The duration of DKA was also significantly longer in the G2 group (p = 0.007). During the pandemic, patients' blood tests showed more anomalies with higher glycated hemoglobin (p = 0.02), C-reactive protein (p = 0.001), and lymphocytosis (p = 0.016). The duration of antibiotic therapy was also significantly longer in G2 (p = 0.01). Conclusions This study showed the impact of the COVID-19 pandemic on the management of diseases other than SARS-CoV-2. Indeed, several factors played a part in the increased incidence of CAIs, which were more severe than in the pre-pandemic period. These included fear of contagion, confinement, and physicians' preoccupation with the pandemic.

RESUMEN

Hypothalamic hamartomas are benign tumors composed of ectopic neural and glial tissue. They have a low prevalence and are usually associated with central precocious puberty or epilepsy with gelastic seizures. The presentation beyond childhood is rare, and the symptoms are not the same as in childhood. Here, we report the case of a woman who presented with secondary amenorrhea and headaches revealing a giant hamartoma of the tuber cinereum (TC). The hormonal assessment showed moderate hyperprolactinemia. Synacthen testing was normal. Magnetic resonance imaging revealed a suprasellar hamartoma on the TC measuring 20 mm with sellar extension. The optic chiasma and cavernous sinuses were clear. Hyperprolactinemia was explained by mechanical compression of the pituitary stalk. The patient started cabergoline orally (1 mg per week) with an improvement of the prolactin levels and had a natural pregnancy six months later without incident. Surgery was not indicated due to the difficult transsphenoidal access and the absence of major clinical symptoms.

RESUMEN

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is a major public health problem. Foot-related complications are common in diabetic patients. The aim of this study is to identify predictive factors for lower limb amputation (LLA) in order to better identify this at-risk population. METHODS: This was a cross-sectional study involving 134 patients who were hospitalised for the management of T2DM complicated by diabetic foot, in the department of endocrinology and diabetology. We included patients with T2DM whose diabetes was diagnosed 10 years ago or more, and who had a diabetic foot problem. Statistical differences between predictors of amputations were tested using: t-tests for numerical variables and chi-square tests for categorical variables. Significant variables were analysed by logistic regression to determine significant predictors. RESULTS: The mean duration of diabetes was 17±7 years. We found that 70% of patients with LLA were older than 50 years (p<10-3). The prevalence of LLA was higher (p=0.015) in patients with diabetes for more than 20 years. We noted that 58% of patients who underwent LLA were hypertensive (p<10-3). The majority of patients with LLA (58%) had abnormal micro-albuminuria (p<10-3). We found that 70% (n=12) of patients with LLA had low-density protein cholesterol levels above the target value (p<10-3). Diabetic foot grade ≥4 (4 or 5) according to Wagner's classification, was present in 24% of amputee patients. Based on a 95% confidence interval level, the independent significant predictive factors for LLA in our patients were: T2DM for more than 20 years, hypertension and diabetic foot grade ≥4. CONCLUSIONS: After multivariate analysis, the significant independent predictive factors associated with LLA were: T2DM for more than 20 years, hypertension, and diabetic foot grade ≥4. Early management of diabetic foot problems is therefore recommended to avoid amputations.
