Tonsillar tuberculosis is the infectious localization of Koch's bacillus in the palatine tonsils. It is rare. Tonsillar tuberculosis associated with miliary tuberculosis is even more exceptional.

Objective: The aim of our work is to report a rare case of tuberculous tonsillitis associated with miliary tuberculosis.

Patient and methods: This was a case of tonsillar tuberculosis associated with miliary tuberculosis. The main complaint was chronic odynophagia, which had been present for 7 months and was associated with weight loss. Questioning also revealed alcohol, tobacco and marijuana consumption.

Results: Oropharyngoscopy revealed an enlarged, ulcerated and hemorrhagic right tonsil, suggesting a malignant lesion. Diagnostic tonsillectomy with anatomopathological examination of the surgical specimen led to the diagnosis of tonsillar tuberculosis. A postoperative chest X-ray revealed tuberculous miliaria. No other tuberculosis site was identified. No other confirmatory biological tests were carried out. The patient was treated with 4 anti-tuberculosis drugs (rifampicin, isoniazid, pyrazinamide, ethambutol) during 2 months and 2 anti-tuberculosis drugs (Rifampicin, Isoniazid) during 4 months. The evolution was favorable and the patient was declared cured at the end of treatment. There was no recurrence after 5 years.

Conclusion: Tonsillar tuberculosis is rare. Tonsillar tuberculosis associated with pulmonary miliaria is even more exceptional. Tonsil biopsy for anatomopathological examination is sufficient for diagnosis. A chest X-ray should be requested as part of the preoperative workup prior to any tonsillar biopsy or tonsillectomy. GeneXpert (MTB/RIF) should be carried out if possible, not only for its value in the biological confirmation of tuberculosis but also to identify rifampicin resistance. Antibacillary treatment often leads to a favorable outcome.

Background: Snakebite clinical trials have often used heterogeneous outcome measures and there is an urgent need for standardisation.

Method: A globally representative group of key stakeholders came together to reach consensus on a globally relevant set of core outcome measurements. Outcome domains and outcome measurement instruments were identified through searching the literature and a systematic review of snakebite clinical trials. Outcome domains were shortlisted by use of a questionnaire and consensus was reached among stakeholders and the patient group through facilitated discussions and voting.

Results: Five universal core outcome measures should be included in all future snakebite clinical trials: mortality, WHO disability assessment scale, patient-specific functional scale, acute allergic reaction by Brown criteria, and serum sickness by formal criteria. Additional syndrome-specific core outcome measures should be used depending on the biting species.

Conclusion: This core outcome measurement set provides global standardisation, supports the priorities of patients and clinicians, enables meta-analysis, and is appropriate for use in low-income and middle-income settings.

Introduction and objectives: Cystic echinococcosis is highly endemic in Algeria and constitutes a major socio-economic problem. Typing the species of the Echinococcus granulosus sensu lato complex circulating in cattle requires the use of a hydatid cyst sampling method adapted to difficult field conditions (high heat and humidity, long transport time). The FTA Card method currently constitutes an effective means of preserving biological samples before their molecular analysis. In the present study, the FTA Card method was used in the collection of hydatid cysts to identify the species of E. granulosus sensu lato circulating in ruminants (intermediate hosts) in eastern Algeria.

Material and methods: A PCR was carried out for 41 samples of hydatid cysts taken from six slaughterhouses in eastern Algeria, targeting the cox1 mitochondrial gene. PCR products were visualized by electrophoresis in a 1% agarose gel.

Results and conclusion: The results of the molecular analysis of all hydatid cyst samples confirmed the presence of E. granulosus sensu stricto in sheep, cattle and camels. The ubiquitous nature of the G1 genotype has been demonstrated. The use of FTA Card sampling is an efficient and simple method to obtain a biological sample in order to characterize the species of E. granulosus sensu lato in Algeria. The good preservation of the DNA in this matrix will make it easier to obtain new molecular data from difficult regions. The identification of the species of the E. granulosus sensu lato complex involved in the biological cycle is an essential prerequisite for the implementation of control measures, since different host species participate in their evolutionary cycle. The characterization of E. granulosus genotypes is essential to define an appropriate control strategy against cystic echinococcosis.

We report the case of a 19-year-old Malian patient, who presented with urethritis and a vesicular rash during the summer of 2022, following a probable heterosexual intercourse. The epidemic context among the male homosexual population and the clinical picture without genital lesions or lymphadenopathy allowed us to discuss both chickenpox and mpox, the latter being finally confirmed by the detection of Monkeypox virus DNA from vesicular fluid.

Introduction: In developing countries, 10% of the population is over 60 years old and this proportion is increasing rapidly. The general objective of this study was to describe the profile and management of the elderly subject aged 60 and over, hospitalized in the ENT (Ear, Nose and Throat) and Head/Neck surgery department of the Sylvanus Olympio University Hospital in Lomé, from 2012 to 2021.

Method: Retrospective descriptive study. After reviewing the files, selection of patients aged 60 and over, regardless of sex, and hospitalized for an ENT pathology from January 2012 to December 2021. Not included in our study were files of elderly subjects hospitalized but whose age was imprecise, or empty or very incomplete files.

Results: A total of 296 cases were included, representing 6.7% of the department's activities. The mean age of the patients was 72 ± 7.3 years with extremes of 60 and 95 years. The age group 6069 years represented 59.5%. The sex ratio M/F was 0.92. Infectious/inflammatory lesions were found in 138 patients (46.6%) including 38.9% of acute cellulitis of dental origin, and tumors were found in 135 patients (45.6%). Tumors were malignant in 59 patients (43.7%) and benign in 76 patients (56.3%). Thyroid was the site of 46 (60.5%) benign lesions and larynx of 29 (49.2%) malignant lesions. Poor oral hygiene, use of non-steroidal anti-inflammatory drugs, diabetes and the combination of smoking and alcohol were the factors favoring the occurrence of acute cellulitis of dental origin in 89.6%, 80.9%, 20.0% and 2.6% of cases respectively (p<0.001). The combination of smoking and alcohol was a factor favoring the occurrence of malignancy in 39% (p<0.001). Surgical treatment was performed in 234 patients (79.1%). With a case lethality rate of 21%, acute cellulitis of dental origin was the leading cause of death (p<0.001).

Conclusion: The most frequent pathologies of the ENT sphere in the elderly in our tropical context were infectious and tumoral, largely dominated by acute cellulitis of dental origin, thyroid adenoma and squamous cell carcinoma of the larynx. Despite the tendency to balance infectious and tumoral pathologies, the proportion of acute cellulitis of dental origin remains twice as high as that of malignant tumors. It contrasts with data from other sub-Saharan series where tumoral pathology remains predominant in the elderly. It is important to provide dental care assistance to the elderly and to advocate for the development of geriatrics and access to universal health coverage for the elderly in Togo.

Introduction: Acute leukemia is both a diagnostic and therapeutic emergency. Our study aimed to describe the prognostic factors and survival of adults with acute leukemia in Burkina Faso.

Patients and methods: Cross-sectional descriptive study with retrospective data collection covering a period of 4.5 years (2018-2022) in two university hospitals in Burkina Faso. Were included all patients over 18 years hospitalized for acute leukemia in these sites with a usable medical record.

Results: A total of 42 cases were collected, of which 45% suffered from acute lymphoblastic leukemia and 43% from acute myeloid leukemia. In 12% of cases, acute leukemia was not classified. The average age was 35 ± 15 years, with extremes of 19 and 72 years. 12% of the patients presented an age of poor prognosis. Comorbidities were present in 14% of patients. The deterioration in general condition was fairly constant with 95% of patients at WHO stages 3 and 4. All patients presented with bone marrow failure syndrome and tumor syndrome was found in 45%. Anemia and thrombocytopenia were present in almost all cases. Hyperleukocytosis at diagnosis was present in 28 patients (67%); among them 18 patients (64%) had leukocytes greater than 50 G/L. Death in hospital was found in 38% of patients and loss of sight in 31%. The median survival was 3 months. Survival was 30% at 6 months and 0% at 12 months.

Conclusion: Acute leukemias are in our practice conditions of poor prognosis with a fairly short survival.

Introduction/rationale: In 2006, the Senegalese government set up a health coverage programme for people aged 60 and over - the Plan Sésame - to provide free medical care in all the country's public health facilities. This scheme has been integrated into the Universal Health Coverage (CMU) promoted from 2013. The objective of the study was to describe and analyse the knowledge and representations of professionals and users about health coverage and the Plan Sésame, the use of the scheme by the elderly, to evaluate the amount of medical expenses incurred during a routine medical consultation for the monitoring of their illness (hypertension and diabetes), and to calculate the out-of-pocket expenses related to the consultation.

Material and methods: Study conducted between July 2020 and October 2021 in two public health facilities in Dakar. Mixed approach: 1/ qualitative study by semi-directive interviews, informal interviews, observations and field diary with 35 people selected according to a reasoned choice procedure with the aim of diversifying gender, age, social status, therapeutic itineraries for 23 people (including 12 women, ages between 60 and 85 years), and professional activities for 12 health actors; 2/ quantitative cross-sectional study by questionnaire of 225 people (including 141 women) aged 60 and over; we calculated the total cost of the consultation and associated prescriptions (complementary examinations and medicines) as well as the remaining medical expenses (out-of-pocket) and the cost of transporting patients. This is a descriptive exploratory study of a non-representative sample of the elderly population in Senegal.

Results: The health professionals interviewed supported the principle of health coverage, but most of them had limited and sometimes imprecise knowledge of the existing schemes and the methods of access or the services covered. Their point of view about the consequences of the Plan Sésame on their practice reveals some contradictions: some complain about the increase in workload, the criticism is extended to all the free schemes which would have a negative impact on daily practice because of the increase in the number of consultations which would be linked to abuse by patients.The interviews highlight the heterogeneity of the knowledge of elderly people about the health coverage intended for them, even though the Plan Sésame has been in place for over ten years. The interviews clearly show that the use of the health coverage system by the elderly depends closely on the information they have and their ability to use it, both for women and men. There is a close link between the level of social integration of people and their use of health coverage: the most socially integrated people are those who know how to use CMU services best. The use of health coverage by the elderly appears to vary according to the individual.Although Plan Sésame is defined as

Charles Louis Alphonse Laveran - 18 June 1845 - 18 May 1922: first French Nobel Prize in Medicine, "in recognition of his work on the role played by protozoa in causing diseases". One hundred years after his death, only written records remain of his work and life. The witnesses to this period are no more. Alphonse Laveran has become an "object" of history.He was deeply involved in a turbulent historical period, marked by crises of regime change (Monarchy/Empire/Republic), military events (French colonial expansion in North Africa from 1830, the wars of 1870 and 1914-1918) and their consequences (the medical impact of infections in the colonial empire and during armed conflicts, the Dreyfus affair, among others), the advent of Pasteurian "microbiology" and the deciphering of the causes and modes of transmission of infectious diseases. A player on the edge of the military and civilian worlds, with their own, sometimes incompatible, visions of the aims and objectives to be pursued, Alphonse Laveran lived through these upheavals in a society in the throes of change, in his family and scientific environment.Paradoxically, the primary sources available to us for learning about this scientist and man are both abundant and "scarce" for us in the 21st century. His scientific publications and many of his speeches at various academies, committees and meetings are for the most part public and accessible, giving us a vision of a professional in scientific and medical research in action, presenting and convincing people of his ideas and theoretical and practical insights. The writings of his contemporaries, both public and private, shed light on - distort? - the man's many facets. On the other hand, there are few surviving sources on the man and his vision of life, his life and that of his family and friends.We will rely on the archives that have been preserved, in particular by the organisations that welcomed him during his military and civilian career, as well as by his wife Marie Laveran and his colleague Marie Phisalix, one of the first doctors of medicine in France and a renowned herpetologist. These two female figures have preserved and contributed to his memory. Let's take a closer look at the man behind the scientist, as we can imagine him through the traces that remain.

Introduction: Myiasis is an infestation of humans or animals by larval forms of brachycetes. Commonly observed locations are otolaryngological and cutaneous. Gastrointestinal localization remains exceptional. In this work, we report the observation of a Moroccan case of gastrointestinal myiasis caused by Drosophila melanogaster. Observation. The patient was a 56-year-old man living in a rural region of northwest Morocco. He was being followed at the National Oncology Institute in Rabat for pulmonary and renal adenocarcinoma and was put on neo-adjuvant chemotherapy with concomitant radiochemotherapy. The patient presented vomiting twice containing about forty small white, circular and hairless worms measuring 4 mm in length. This sample was sent to the parasitology and mycology laboratory for identification. Microscopic study of the larvae and adult flies obtained after rearing in the laboratory of parasitology allowed the diagnosis of myiasis caused by Drosophila melanogaster.

Discussion/conclusion: This observation is noteworthy for both its exceptional anatomical localization and the implicated parasite species.

Background: Scabies is a contagious, pruritic, cosmopolitan dermatosis, widespread especially in human communities, due to parasitism by a mite Sarcoptes scabiei var hominis A lack of hygiene and overcrowding inside the houses are favourable factors. The aim of our study was to determine the prevalence and factors associated with the occurrence of human scabies in the prison environment in Dosso (Niger).

Materials and methods: Prospective descriptive cross-sectional study conducted in November 2022 in the civil prison of Dosso on authorization of the prison administration. The collected data were sociodemographic characteristics, personal history of pruritus and its characteristics, risk factors related to hygiene and conditions of incarceration, examination performed by a dermatologist to look for clinical signs of scabies. The diagnosis was retained in any inmate presenting one or more elements at the interrogation and at the physical examination.

Results: Out of a total of 352 inmates, 43 (38 males and 5 females) had scabies, a prevalence of 12%. The average age was 33 with extremes of 18 and 62 years. Of the scabies patients, 9% reported a history of intense, sleepless pruritus prior to incarceration. Most of the inmates, 86%, were in cells with more than 20 inmates. Among those with scabies, 42% showered twice a day, 81% changed clothes after showering and 74% used soap regularly for washing. The topography of the lesions was external genitalia (37%), buttocks (21%), inner thighs (16%), interdigital spaces (9%), elbows (9%) and wrists (7%). The inmates were informed about the disease, treatment information was explained to them, and they attended a session on hygiene promotion. All cases of scabies detected were prescribed a local treatment based on benzyl benzoate lotion 25%.

Discussion/conclusion: Human scabies is common in the prison environment in Dosso. Too often, scabies goes undetected and is confused with other pruritic dermatoses, such as eczema or atopic dermatitis. Prison medical staff should be trained in scabies in order to prevent scabies outbreaks. The authorities in the region should make the improvement of hygiene and detention conditions in prisons their priority.
