Introduction :Congenital adrenal hyperplasia (CAH) is the most common cause of primary adrenal insufficiency. It is a rare monogenic recessive disorder. In African setting in absence of neonatal screening, the diagnosis is still late, based on a clinical approach. During this clinical enquiry, information from past history or pedigree of the patient is of a huge importance and may revealed surprises. Patients and Methods: In this observational study, we retrospectively included all patients with a diagnosis of CAH. The diagnosis of CAH was retained based on a high 17 hydroxyprogesterone level in addition to clinical and morphological findings. From patients’ files, we extracted data on family history of disease, pedigree, clinical findings and genetics when available of 39 patients from two endocrinopeadiatric centers. Results: In 13 (30%) families, we found 20 reported deaths of infant less than 12 months. In these 13 families, half of the patients followed had 21 hydroxylase deficiencies and had 11 hydroxylase deficiencies. Unsurprisingly, we suspected adrenal insufficiency in these patients at verbal autopsy even in families with a patient with 11 hydroxylase deficiency. Other non DSD malformations or genetic disorders with apparently no link with CAH were reported in 3 families. The father of a patient reported to have hypospadias. Conclusion: Each diagnosis of CAH made in our context is visible part of an iceberg. Behind a diagnosis of CAH made in our setting, is a long course of care, a dramatic past history revealing access to appropriate care disparity. Neonatal screening should thus be considered as an emergency.

Open Journal of Internal Medicine 2024年第1期14卷 30-42页

作者： Andia Abdoulkader Audrey Rouet Benedicte Dieudonné Jacque Boaddert charlotte Tomeo Sandrine Greffard Marc Verny Department of Geriatric of Pitie Salpetrière Hospital 47-83 Boulevard de l’H&ocircpital Paris France

Alzheimer’s disease (AD) is the most common neurodegenerative disease causing an alteration of life quality in the terminal stage. The purpose was to report 14 years of experience about the early impact on the quality of life of patients with AD. Methodology: Descriptive retrospective study over 14 years in the geriatric department of Pitié Salpêtrière Hospital, using the activity of daily living, Instrumental activity of daily living, neuropsychological inventory and Hoen Yahr scale evaluated at the time of diagnosis of AD according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer Disease’s and Related Disorders Association diagnostic criteria. Results: A total of 214 exploitable files had been listed. At the moment of diagnosis, the mean age was 82.1 years with extremes 68 to 95 with sex ratio 1.6 in women’s favor. The mean socio-cultural level was 4.9 with extremes about 0 to 7. There was poly pathology with a mean Cumulative Illness Rate Scale = 4.6 with extremes 0 to 16. the mean cognitive status was moderate = 22.5 with extremes 0 to 30. Quality life showed moderate impairment of IADl = 9.2 with extreme 3 to 11 compared to activity of daily living. The activity of daily living was more affected in 68 - 80-year-olds, while poly pathology impacted more on IADl in men. The cognitive impairment was more deficient in IADl when the MMSE test was low. The common disorders at the NPI were psychological, behavioral and psychotic. Conclusion: At the early diagnosis of Alzheimer’s Disease cognitive deficiencies were predominant and influenced on global Instrumental activity and psychological, behavioral disorders.

Introduction: Sickle cell anaemia is a hereditary disease that combines physical and psychological manifestations, including suicidal tendencies. So far, to our knowledge, no study has been conducted on suicidal behaviours among people with sickle cell disease in Cameroon. This is what justifies our study on the prevalence and factors related to suicidal behaviors in our study population. Methods: We conducted a cross-sectional, analytical study of 171 sickle cell patients aged from 12 years upwards who came to the sickle cell disease care service of the laquintinie Hospital in Douala, over a period of 6 months, that is, from 1 January to 31 June 2022. Data were collected using a structured questionnaire with questions on suicidal behaviours based on the “MINI” (Mini International Neuropsychiatric Interview). The data were processed using the SPSS 26.0 software. The related factors were studied in both a bivariate and multivariate analysis. Results: Female sickle cell patients accounted for 60.2% of the sample. The mean age was 23.36 ± 8.42 years. Suicidal ideation was prevalent in 56% of cases and 13% attempted suicide. The factors most associated with suicidal ideation were: primary level of education (OR = 0.08 (0.09 - 0.79);p = 0.03), feeling unworthy of life (OR = 0.40 (0.08 - 1.96);p = 0.02), not often being considered by those around them (OR = 2.97 (1.26 - 6.99);p = 0.01), lack of family support (OR = 0.34 (0.15 - 0.77);p = 0.01). Meanwhile, the factors associated with suicide attempts were: the fact of being rarely exposed to suicide-related media (OR = 4.17 (1.40 - 71.80);p = 0.03), and a constant feeling of sadness when returning home (OR = 18.02 (1.59 - 20.55);p = 0.01). Conclusion: More than half of sickle cell patients had had suicidal thoughts and 1/6 had made at least one suicide attempt, women and young adults being the most concerned. It is therefore necessary to ensure optimum psychological care for patients with sickle cell disease.

Dear Editor,Allogeneic or autologous hematopoietic stem cell transplantation(HSCT)concerns an increasing number of ***,89070 allogeneic and autologous HSCT procedures were reported in 2016,representing a 7%increase per year since 1991.1 Improved transplant strategies and therapeutic efficacy have made HSCT a curative option for various indications,mostly comprising malignant blood cell pathologies but also including solid tumors or benign conditions.2 The conditioning regimen for transplantation often includes alkylating agents and/or total body irradiation(TBI).2 These treatments usually lead to permanent infertility.3 In men,the consequences include the impairment and reduction of Sertoli and leydig cells,leading to the suppression of the spermatogonia pool and increased release of gonadotrophin.3 Although sperm banking can mitigate the risk of infertility.
