Introduction: Thyroidectomy is a surgical procedure to remove all or part of the thyroid gland. The aim of this study was to report the results of thyroidectomy in the general surgery department of the Hôpital national Ignace Deen/CHU de Conakry. Methodology: This was a retrospective study, of seven (07) years (January 1, 2016 - August 31, 2023), in the General Surgery Department of the Ignace Deen National Hospital-CHU in Conakry. We included all records of patients admitted and operated on for thyroidectomy and with up-to-date medical records. The variables were epidemiological, clinical and therapeutic. Results: During the study period, we recorded 3221 cases of surgery, including 40 thyroidectomies (1.24% of cases). The average age was 42.4 years. Women were the most represented, with a sex ratio of 0.16. The reason for consultation was anterior cervical swelling in 86% (n = 25) of cases, followed by signs of cervical compression 21% (n = 6) and signs of thyrotoxicosis 31% (n = 9). Indications for thyroidectomy were dominated by homogeneous goitres in 69% (n = 20) of cases, basedow’s disease in 20.7% (n = 6) and nodular goitres in 6.9% (n = 2) of cases. The surgical procedures were lobo-isthmectomies in 72.4% (n = 21), subtotal thyroidectomies 13.8% (n = 4), total thyroidectomies 10.3% (n = 3). Postoperative follow-up was straightforward in 69% (n = 20). Complications included haemorrhage in 20.7% (n = 6) and recurrence in 6.9% (n = 2). The average hospital stay was 7 days. Conclusion: Thyroidectomy is a relatively frequent surgical procedure in our department. Indications are dominated by homogeneous goitres. Morbidity is related to hemorrhage. Rigorous hemostasis could improve the quality of thyroidectomy.

Objective: The objective of this study was to investigate the etiologies of infertility and to determine the contribution of hysterosalpingography coupled with ultrasound in the exploration of female infertility at Donka University Hospital. Methodology: This was a prospective descriptive cross-sectional study carried out in the Radiology Department of Donka National Hospital over a period of ten (10) months. It involved 78 women who came to the department for hysterosalpingography and/or pelvic ultrasound examinations, as part of the exploration of infertility. Data collection involved the use of pre-established survey forms to gather information on the parameters studied. Sociodemographic parameters, ultrasound and hysterosalpingography results were studied. A correlation was made between age at marriage and infertility to determine whether early marriage has an impact on primary infertility, with a statically significant result for p value greater than 0.05. Results: The mean age of our patients was 33.7 ± 5.6 years, with extremes of 18 and 35 years. The 18-35 age group was the most represented, with a frequency of 80.7%. The 34% of our patients were married before the age of 18, with a marriage duration ranging from 6 months to 15 years. The indication for investigations was dominated by secondary infertility, with a frequency of 65%, followed by primary infertility (35%). All our women underwent ultrasound-hysterosalpingography, i.e. 100%, in search of the cause of infertility. Ultrasound was pathological in 35.8%. The most common ultrasound lesions were myomas and ovarian dystrophies, with 12.8% each. However, hysterosalpingography was pathological in 35%. Tubal obstructions affected almost a third of our women (29.5%), followed by phimosis and tubo-peritoneal adhesions. Conclusion: Diagnostic evaluation of infertility requires a multidisciplinary approach, including collaboration between infertility gynecologists, radiologists and other infertility specialist

Introduction: Growth is a reflection of a child’s health and nutritional status. Children with sickle cell disease often have slower statural and weight development. The aim of this study was to evaluate the nutritional profile of children with sickle cell disease (SCD) registered in the CEMECO centre database. Methodology: This was a cross-sectional study with simple random sampling of children aged 1 to 16 years registered in the clinic database. Results: We collected information on 208 children, 121 of whom had sickle cell disease and 87 of whom were normal, with a sex ratio of 1.02. The mean age of the sickle cell patients was 8.7 ± 4.4 years, while that of the non-sickle cell patients was 9.5 ± 4 years. Haemoglobin electrophoresis revealed 103 homozygous (SS), 18 double heterozygous (SC, SBetaThal, SE) and 87 normal (AA) and/or sickle cell trait (AS) sickle cell cases. We observed a significant difference in the height/age ratio (P ¥). Conclusion: The results of our study revealed stunted growth in children with sickle cell disease.

Introduction: External otitis (OE) is an acute or chronic inflammation or infection of the external ear resulting from an imbalance in the external auditory canal secondary to microtrauma, maceration, eczema, or a foreign body in the external auditory canal. Objective: To study cases of external otitis at the Mamou Regional Hospital. Materials and Methods: This was a prospective descriptive study conducted over a period of six (6) months from July 1st to December 31st, 2016. It included all patients admitted to the ENT department of the Mamou Regional Hospital. Results: During the study period, 712 patients were admitted to the department for various pathologies, of which 103 met our selection criteria, representing a frequency of 14.46%. The mean age of the patients was 33.74 years with a range of 1 to 90 years. Males predominated in the sample, accounting for 59.22%. The vast majority of patients resided in urban areas, constituting 61.17% of the sample. In our study, all patients consulted for otalgia (100%), and over half (53.39%) for hypoacusis. We formally identified rhinitis in 66.66% of cases, while diabetes was found in only 4 patients (11.11%). Otomycosis was the most commonly identified condition (53.39%), followed by furuncles (33.98%). Ear drops containing antibiotics were administered to all patients, although 66.60% received antibiotic therapy. Conclusion: External otitis is a relatively common condition, particularly among children and the elderly. Diagnosis can be made based on pain upon traction of the pinna and pressure on the tragus.
