In many outbreaks, patients and healthcare workers are particularly at risk from nosocomial infections as a result of non-effective disinfection methods. With increasing incidence of viral infections such as severe acute respiratory syndrome, in one hand, and the increase in the rate of antibiotic resistant bacteria associated with nosocomial infections in other hand, there is a need to design novel engineering tools for inactivation of nosocomial pathogens. Ultraviolet germicidal irradiation (UVGI) is considered as a promising method to inactivate bacteria and viruses. This paper presents UV-C Based disinfection tools monitored by mobile application, designed for hospital and Epidemic Treatment Center. The evolution of the irradiation intensity over time was evaluated, and the theorical disinfection duration for several nosocomial pathogens was determined. In the case of SARS-CoV2, less than 12 minutes were needed to achieve 99.99% viral reduction in a room of 36 sqm.

Dermoid cyst of the oral floor is rare benign tumour, who having three histological aspects: dermoid, teratoid and epidermoid. This one is characterized by the presence of a squamous stratified epithelium with cutaneous remnants. It may occur in any part of the body, however their frequency in the ENT sphere is relatively scarce. Seven per cent (7%) only of epidermoid cysts occur in the cervico-facial area, 1.6% of which locate at the floor level. When they are located submandibular, they can pose diagnostic difficulties and look like a tumour of the submaxillary gland. We report two cases of epidermoid cyst of the floor. Both patients suffered from swelling of the submandibular gland. Magnetic Resonance Imaging was not requested due to lack of resources. However, surgery allowed in both cases the excision of a cyst next to a normal submandibular gland. Patients did well post operatively.

Background: Endoscopic third ventriculocisternostomy (ETV) is the most common neuroendoscopic technique in the treatment of noncommunicating hydrocephalus. Since its introduction, ETV has been a safe alternative to ventriculoperitoneal shunt (VP shunt), which has a high complication rate with significant socio-economic consequences. The authors report the results of ETV performed in the neurosurgical department of FANN teaching hospital in Dakar. Methods: This retrospective study presents the results of ETV performed in 513 patients with hydrocephalus of various etiologies, ranging from February 2010 to February 2018. We have included in our series from 2010 to 2016, all patients with clinically revealed non-communicating hydrocephalus followed by a brain computed tomography (CT) scan or brain magnetic resonance imaging (MRI) and who have benefited from an ETV, in which the ETV Success Score was evaluated. Results: The mean age of our patients was 14.10 years, with 298 (58%) males. The clinical symptomatology varied in both children and adults and manifested in children as macrocrania in 67.8% of the patients, while in adults, it manifested as raised intracranial pressure (ICP) in 87.5% of patients. A brain CT scan was performed in 461 (89.86%) of patients. The causes of hydrocephalus were dominated in 49% of patients by malformative pathologies, followed by tumors in 41% of patients, infections in 2.33% of patients, and normal-pressure hydrocephalus in 3.8% of patients. During the postoperative period, we found 21.41% of various complications. Conclusions: The findings in our series were compared to those in the literature and were satisfactory, thus proving the effectiveness and safety of ventriculocisternostomy in our department. In resource-limited countries, ETV can be performed with good results and less mortality and morbidity.

Brain metastases (BM) are the most frequent brain cancer. There are few studies on BM in Senegal. The aim of this study was to describe epidemiological, clinical, diagnosis, treatment and outcome features of patients diagnosed with BM. We conducted a retrospective and descriptive study of patients diagnosed with brain tumors and regularly followed at the neurosurgery department of the “Fann Teaching Hospital (CHNU-Fann)” of Dakar (Senegal) between from January 2010 to December 2017. The medical records of all the patients with evidence histologically diagnosed with BM were reviewed. In our study, 682 medical records of patients with brain tumors were reviewed, and only 20 showed histological evidence of BM (2.9%). The mean age was 45.45 years. The sex-ratio was 0.43. Brain CT scan was performed in all the patients (100%) and brain MRI in 3 patients. The brain lesions were multiple in 70% of the patients and single in 30%. The histological type of BM was adenocarcinoma (55%) and squamous cell carcinoma (45%). Five types of primary cancers were found: lung cancer (50%), breast cancer (30%), colorectal cancer (10%), melanoma (5%) and one undetermined cancer. All the patients had extirpation surgery;50% of the patients died 7 days after the surgery;25% had a survival of 3 months after the surgery and 25% of the patients were lost of sight. Conclusion: The improvement of the screening and diagnosis tests, and the use of the radiation treatment and chemotherapy could allow early management and decrease the death’s frequency of the patients with BM in Senegal.

Darier-Ferrand dermatofibrosarcoma (DFS) is a cutaneous mesenchymal tumor of intermediate malignancy. It is a rare but not exceptional tumor, accounting for 0.1% of malignant skin tumors. Histological examination is essential for diagnosis. Wide surgical excision is the standard treatment. DFS is a tumor whose prognosis and evolutionary risk are mainly linked to the delay in diagnosis and the quality of the first excision. Late diagnosis makes excision and reconstruction surgery difficult. The chances of recovery in the case of well-performed primary surgery are significantly greater than in the case of salvage surgery. To improve prognosis, early, codified, multidisciplinary management is essential. In our African context, and especially in the case of patients living in rural areas, errant diagnoses are often found hence the importance of raising awareness and providing information to healthcare personnel. We report a case of an enlarged left supraclavicular Darier-Ferrand dermatofibrosarcoma. The patient had come for a late consultation at a stage when the tumour was large. The CT scan was a great help in the pre-operative phase. The patient underwent complete surgical excision, the postoperative course was straightforward and the histology of the surgical specimen confirmed the diagnosis. The resection margins were healthy. The patient is alive at one year with no recurrence or metastasis.

Introduction: Despite current progress, tuberculosis remains a major public health problem, given its still high incidence, prevalence, and mortality, particularly in sub-Saharan African countries, including Senegal. This risk is higher for immunocompromised people. Complications and comorbidities can also affect the course of the disease, affecting the prognosis. It is in this context that this study was undertaken with the objective of determining the risk factors and complications in patients hospitalized for tuberculosis. Materials and Methods: This was a retrospective and descriptive study carried out in 2021, from records of patients hospitalized for tuberculosis from January 1, 2017, to December 31, 2019, at the Pulmonology Department of Fann. Inclusion criteria were all patients on TB treatment after diagnosis of tuberculosis has been confirmed bacteriologically or clinically according to the World Health Organization’s TB case definition. Multidrug-resistant TB was excluded. Results: Out of 4516 hospitalized patients, 20.96% of patients were tuberculosis patients. The sex ratio was 2.18. 4/5 of the patients were between 18 and 39 years old. The main contributing factors of TB found were undernutrition (93.13%), active smoking (36.75%) and diabetes (35.97%). The time between hospitalization and onset of symptoms was greater than 2 months in 60.53% of cases. A complication was noted in 89.10% of patients, particularly bacterial/viral bronchopulmonary co-infection (31.15%). The trend was favorable in 88.49% of cases. It resulted in death in 10.98% of cases. Conclusion: Most integrated-care nutritional support programs focus on HIV. Undernutrition appears to play a much more important role than HIV in the extent of TB in poor countries. It creates a vicious circle with tuberculosis, one of the components of which is immunosuppression and the increased frequency of complications such as bacterial/viral community/nosocomial co-infection, the actual incidence of w

Introduction: Congenital heart disease (CHD) is a malformation of the heart present at birth and resulting from a developmental defect during embryonic life. The aim was to assess CHD in rural areas. Methodology: This is a retrospective study conducted over a period of 2 years in rural Senegal. Results: During the study period, we collected 79 patients with CHD, representing a hospital prevalence of 2.6%. The mean age at diagnosis was 17.05 months and the sex ratio was 1.19. The mean birth weight was 2826 g. The main comorbidities were anaemia (54.43%) and respiratory infections 38 cases (48.10%). Respiratory distress was the most common sign with 98.73%. Radiological cardiomegaly was noted in 86.7%. The most frequent CHD were interventricular septal defect (IVD) 21.51% and atrial septal defect (ASD) 8.86%. No patient was able to receive surgical treatment. Seven children died (8.86%) and 21 children were lost to follow-up (26.58%). On Doppler echocardiography, 16.45% of the patients had pulmonary arterial hypertension (PAH). Conclusion: In light of this work, emphasis should be placed on the quality of antenatal consultations, the quality of management and the regular availability of echocardiography and a cardio-paediatrician in order to reduce morbidity and mortality.

“Locked twins” is a rare event occurring in about 1 in every 1000 twin births. A 21-year-old primigravida with a 31-week twin pregnancy was admitted for delivery. The head of the first twin was locked to the chin of the second twin at the top of the symphysis pubis. Caesarean section was performed allowing the delivery of both dead twins. Twins gestations with first twin in the breech presentation raise index of suspicion of potential locked twin. However, management of such situation is controversial with most authors and colleges recommending caesarean section to avoid interlocking heads. We report another rare case of interlocking heads and bring up the topic about management of breech-first twin deliveries.
