Assessment of the Effectiveness of Corticosteroid Infiltrations in the Ignace Deen University Hospital Center in Conakry.

Introduction Corticosteroid infiltration is a medical procedure which consists of the injection of a corticosteroid locally, into a painful site. Thus the objective of this study was to evaluate the effectiveness of corticosteroid infiltrations in the rheumatology department of the Ignace Deen University Hospital in Conakry (Guinea). Patients and method This was a prospective descriptive and analytical survey that lasted one year from July 2021 to July 2022 carried out in the rheumatology department of the Ignace Deen University Hospital in Conakry. We included all patients who had received corticosteroid infiltration. The infiltration was carried out by a rheumatologist either by anatomical or ultrasound-guided identification. Results During the study period, we recorded 1452 observations including 508 (35%) cases of corticosteroid infiltration. The average age was 53.7 years +/- 12.7 years with the majority of our patients were young adults (68%). Females predominated (55%), with a sex ratio (M/F) of 0.80. The infiltrations were mainly indicated for osteoarthritis, particularly knee osteoarthritis in 264 (52%) of cases and lumbarthrosis in 204 (40.2%) of cases, followed by rheumatoid arthritis (RA) in 216 (42.5%) of cases, gout in 183 (36%) of cases and lumbosciatica in 118 (23.2%) of cases. Dexamethasone was the corticosteroid predominantly used in 46.2% of cases. The associated medications were lidocaine in 93% of cases. The intensity of pain remained unchanged in 152 (30%) patients despite the infiltration sessions. Conclusion In our study, the majority of patients who benefited from cortisone infiltration were young adults, with females predominating. Osteoarthritis and rheumatoid arthritis were the main indications for infiltration, and dexamethasone was the most commonly used corticosteroid. The study demonstrated the efficacy of cortisone infiltration, with improvement in pain intensity in some patients (70% of cases). For others, however, the pain remained unchanged.

Factors determining membership in community-based health insurance in West Africa: a scoping review.

BACKGROUND: In many low-income countries, households bear most of the health care costs. Community-based health insurance (CBHI) schemes have multiplied since the 1990s in West Africa. They have significantly improved their members' access to health care. However, a large proportion of users are reluctant to subscribe to a local CBHI. Identifying the major factors affecting membership will be useful for improving CBHI coverage. The objective of this research is to obtain a general overview of existing evidence on the determinants of CBHI membership in West Africa. METHODS: A review of studies reporting on the factors determining membership in CBHI schemes in West Africa was conducted using guidelines developed by the Joanna Briggs Institute. Several databases were searched (PubMed, ScienceDirect, Global Health database, Embase, EconLit, Cairn.info, BDPS, Cochrane database and Google Scholar) for relevant articles available by August 15, 2022, with no methodological or linguistic restrictions in electronic databases and grey literature. RESULTS: The initial literature search resulted in 1611 studies, and 10 studies were identified by other sources. After eliminating duplicates, we reviewed the titles of the remaining 1275 studies and excluded 1080 irrelevant studies based on title and 124 studies based on abstracts. Of the 71 full texts assessed for eligibility, 32 additional papers were excluded (not relevant, outside West Africa, poorly described results) and finally 39 studies were included in the synthesis. Factors that negatively affect CBHI membership include advanced age, low education, low household income, poor quality of care, lack of trust in providers and remoteness, rules considered too strict or inappropriate, low trust in administrators and inadequate information campaign. CONCLUSIONS: This study shows many lessons to be learned from a variety of countries and initiatives that could make CBHI an effective tool for increasing access to quality health care in order to achieve universal health coverage. Coverage through CBHI schemes could be improved through communication, improved education and targeted financial support.

Predictors of stroke favorable functional outcome in Guinea, results from the Conakry stroke registry.

Low- to middle-income countries (LMICs) now bear most of the stroke burden. In LMICs, stroke epidemiology and health care systems are different from HICs. Therefore, a high-income country (HIC)-based predictive model may not correspond to the LMIC stroke context. Identify the impact of modifiable variables in acute stroke management in Conakry, Guinea as potential predictors of favorable stroke outcome. Data were extracted from the Conakry stroke registry that includes 1018 patients. A logistic regression model was built to predict favorable stroke outcomes, defined as mRS 0-2. Age, admission NIHSS score, mean arterial blood pressure and capillary glycemia were chosen as covariates. Delay to brain CT imaging under 24 h from symptom onset, fever, presence of sores and abnormal lung auscultation were included as factors. NIHSS score on admission, age and ischemic stroke were included in the null model as nuisance parameters to determine the contribution of modifiable variables to predict stroke favorable outcome. Lower admission NIHSS, brain CT imaging within 24 h of symptoms onset and lower mean arterial blood pressure emerged as a significant positive predictors of favorable stroke outcome with respective odd ratios (OR) of 1.35 [1.28-1.43], 2.1 [1.16-3.8] and 1.01 [1.01-1.04]. The presence of fever or sores impacted negatively stroke favorable outcomes with OR of 0.3 [0.1-0.85] and 0.25 [0.14-0.45]. The area under receiver operating characteristic curves (AUC) of the model was 0.86. This model explained 44.5% of the variability of the favorable stroke outcome with 10.2% of the variability explained by the modifiable variables when admission NIHSS, and ischemic stroke were included in the null model as nuisance parameter. In the Conakry stroke registry, using a logistic regression to predict stroke favorable outcome, five variables that led to an AUC of 0.86: admission NIHSS, early brain CT imaging, fever, sores and mean blood pressure. This paves the way for future public health interventions to test whether modulating amendable variables leads to increased favorable stroke outcomes in LMICs.

Lupus Pernio in Chronic Sarcoidosis.

Lupus pernio (LP) is characterized by the association between insidious purpuric or purplish blue lesions localized in the nose, cheeks, lips, and ears and swelling of the fingers and toes. We report a case of chronic sarcoidosis with lupus pernio in a 34-year-old male. The diagnosis of sarcoidosis was made on the basis of clinical data and imaging results and confirmed by skin biopsy, which showed numerous epithelioid granulomas surrounded by a non-caseous inflammatory crown. Treatment with prednisolone was started. It is important to make an early diagnosis to avoid a delay in treatment and worsening of the functional and psychological prognosis.

Synovitis, Acne, Pustulosis, Hyperostosis, Osteitis (SAPHO) Syndrome: Clinical and Therapeutic Aspects.

Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome is a rare entity. It is frequently under-detected. We report the case of SAPHO syndrome in a 38-year-old woman, seen in consultation for pain and swelling of the anterior chest wall affecting the sternoclavicular and sternocostal joints predominantly on the right, and low back pain with an inflammatory appearance with peripheral damage, especially in the legs. We also found in our patient episodes of palmoplantar pustulosis. The diagnosis of SAPHO syndrome was retained in accordance with Kahn's diagnostic criteria, and the osteitis was confirmed by morphological examinations (CT scan, MRI, and bone scintigraphy). The patient was treated with non-steroidal anti-inflammatory drugs and methotrexate with good clinical improvement.

Acceptability of COVID-19 vaccination among health care workers: a cross-sectional survey in Morocco.

INTRODUCTION: This study aimed to evaluate the acceptability of COVID-19 vaccination among health care workers prior to the start of the COVID-19 vaccination campaign in Morocco. METHODS: This cross-sectional study was conducted in the Cheikh Khalifa University Hospital of Casablanca-Morocco. Utilizing a web-based platform surveys were distributed over a 3-week period via professional mailing list and social media. Odds ratios and 95% confidence intervals were estimated by using logistic regression models. RESULTS: A total of 303 health care workers participated in this study. The results showed a relatively high rate of vaccination acceptability (62.0%) among health care workers included in this study. Participants were more likely to accept the COVID-19 vaccine if they were physician, nurse, or technician (OR 1.79; 95% CI: 1.09-2.95), had high score of confidence in the information circulating about COVID-19 (OR 1.91; 95% CI: 1.36-2.69), or had high score of perceived severity of COVID-19 (OR 1.55; 95% CI: 1.11-2.15). Reasons of hesitation/or refusal of COVID-19 vaccine were fear of the likely side effects of the vaccine for 74.8% of participants, and concern about the effectiveness of the vaccine for 47.8%. CONCLUSION: This study showed a relatively high rate of the COVID-19 vaccination acceptance among health care workers in Morocco. Willingness to be vaccinated was significantly associated with job category, confidence in the information circulating about COVID-19, and perceived severity of COVID-19. These results could be useful in the development of educational interventions to increase the acceptance of COVID-19 vaccine among health care workers in Morocco and similar settings.

Sjögren's syndrome in children: about 15 cases in Guinea Conakry.

OBJECTIVES: Sjögren's syndrome is rare in children and most often secondary. It frequently affects girls and is characterized by dry eye syndrome, mouth and sometimes systemic involvement. Its diagnosis is difficult to establish in children. We report a series of 15 cases of Sjögren's syndrome in order to clarify the peculiarities of this condition in children. PATIENTS AND METHODS: This retrospective study was carried out over a 2-year period focused on children under 16 years of age who had been followed for Sjögren's syndrome in the rheumatology and pediatric departments. Patient data were collected and then analyzed by STATA/SE version 11.2 software. Anonymity and respect for ethical rules were the norm. There was no connection between the patients and the researchers. DESCRIPTION OF CASES: The mean age of the patients was 11 years with extremes of 5-15 years. History reveals that a dry mouth was found in more than half of the cases, or in 10 (66.7%) patients. Clinical examination found oral ulceration and periodontitis in equal proportions, 6 (40%). The immunological workup and the biopsy of the accessory salivary glands served as diagnostic evidence in the 15 patients according to the US-European criteria of 2002. CONCLUSION: Sjögren's syndrome is a rare entity in pediatrics. Its diagnosis is difficult to establish in pediatrics and its severity is linked to the occurrence of late visceral and lymphomatous sicca syndrome. Rapid diagnosis and initiation of a synthetic antimalarial (hydroxychloroquine) increases the hope of a cure.

Interest of the thoracic scanner in the diagnosis of COVID-19: study of 35 cases in the Republic of Guinea.

INTRODUCTION: the aim of this work is to evaluate the contribution of thoracic computed tomography (CT) in the diagnosis of COVID-19 in Guinea. METHODS: this was a retrospective study with data recorded over a 2 Month period. Records of patients who tested positive on chest CT without contrast injection on admission were included in this study. Not included are those who did or did not perform a chest CT scan after confirmation of the diagnosis by RT-PCR. The data were collected under the direction of the National Health Security Agency (ANSS) and analysed using STATA/SE version 11.2 software. RESULTS: all patients tested performed a chest CT scan without contrast injection while awaiting the RT-PCR test result. Eighty percent (80%) of patients had lesions characteristic of COVID-19 viral pneumonia on chest CT. The reverse transcriptase PCR (RT-PCR) test was later positive in 33 patients (94.28%) and negative in 2 (5.71%). CONCLUSION: it is noted from this study that chest computed tomography is a critical tool in the rapid diagnosis of COVID-19 infection. Its systematization in all patients suspected in our dispute, would facilitate diagnosis while waiting for confirmation by RT-PCR and would limit the loss of cases.

Presentation of a case of Bruton type primary agammaglobulinemia in Guinea.

X-linked agammaglobulinemia (XLA) is a rare genetic disease caused by a mutation in the Bruton tyrosine kinase (BTK) gene. It is characterized by a profound deficiency of B cells and a decrease in all classes of immunoglobulins (Ig). We report one case in a 3-year-old boy seen for recurrent acute otitis media, perineal abscess, oligoarthritis. The serum immunoglobulin (Ig) assay showed an IgG level of 0.6g/l. IgM and IgA are indosable. Marrow immunophenotyping showed an absence of precursor B less than 1%. Molecular biology confirmed Burton's disease (stop mutation, C37C) in exon 2 of the BTK gene. Treatment with intravenous immunoglogulin was started.

Cerebrovascular accidents indicative of COVID-19 infection: about 4 observations in Guinea.

INTRODUCTION: Coronavirus is a virus with potential to target the nervous and respiratory systems. The aim of this work is to establish the prevalence of strokes in COVID19 positive patients in Guinea. METHODS: All patients with stroke confirmed by brain imaging and COVID-positive PCR were included in this study. Retrospective patient data were obtained from medical records. Informed consent was obtained. RESULTS: The RT-PCR confirmed the initial diagnosis and the chest CT scan provided a good diagnostic orientation. Brain imaging identified ischemic brain lesions. We report the case of four patients with stroke and a COVID-19 incidental finding in Guinea. CONCLUSION: This work shows that the onset of ischemic stroke associated with COVID-19 is generally delayed, but can occur both early and late in the course of the disease. More attention is needed because the early symptoms of viral attack are not just pulmonary.

COVID-19 infection during autoimmune disease: study of 2 cases in Republic of Guinea.

INTRODUCTION: Coronavirus is a virus that can target the respiratory, musculoskeletal systems with a cascade of inflammatory processes. The objective of this work is to establish the link between autoimmune diseases and a COVID-19 infection in Guinea. METHODS: Retrospective patient data were obtained from medical records. Informed consent was obtained under the direction of the national health security agency (ANSS). RESULTS: We report the case of two patients aged 52 and 64 years respectively, known to have rheumatoid arthritis (RA) and systemic scleroderma (SDS) admitted with clinical signs suggesting underlying infection with COVID-19. They were tested with RT-PCR, which was positive within hours. CONCLUSION: In view of the rapid clinical worsening of patients with COVID-19 infection and autoimmune diseases, increased surveillance should be undertaken with abstinence of any factors that might weaken the immunity of these patients.
