Prevalence of Work-Aggravated Asthma among Bakery Workers in Abidjan (Cote d’Ivoire)

Introduction: Work-aggravated asthma is pre-existing or concomitant asthma whose symptoms are aggravated by the work environment. The aim of this study was to determine the prevalence of this pathology and its associated factors among bakery workers in Abidjan. Materials and Methods: This descriptive and analytical cross-sectional study was conducted over a period of four (4) months from 18 December 2019 to 18 April 2020. Two questionnaires were used, one on employees and the other on the indoor environment of bakeries. In addition, a spirometry test was performed on all bakery workers. Statistical analysis was performed using stata 15.1 software. Results: A total of 599 bakery employees, including bakers (59.73%), sales assistants/ cashiers (23.52%), cleaners (6.34%) and administrative staff (10.18%), were investigated. The mean age was 30.8 ± 8 years, with a sex ratio (M/F) = 2.2. Asthma symptoms were found in 95 (15.86%) employees, of whom 74 (77.9%) had work-related asthma and 11 (14.9%) had asthma aggravated by work. The factors associated with work-aggravated asthma were personal or family history of allergy or atopy [ORa = 3.75;CI95%: 1.56 - 8.93;p = 0.003], exposure to dust [ORa = 5.01;CI95%: 1.43 - 7.50;p = 0.011] and humidity level (60% - 70%) [ORa = 1.80;CI 95%: 0.99 - 3.28;p = 0.05]. Conclusion: Work-aggravated asthma is a reality in bakeries in Abidjan, with an estimated prevalence of 14.9%. Two of the three factors associated with this condition suggest a link with indoor air pollution. Combating air pollution in these establishments must therefore be a priority for the relevant authorities, in order to provide employees with a working environment that protects their health.

Adverse Events following AstraZeneca COVID-19 Vaccination: A Case Study in Abidjan, Côte d’Ivoire

Introduction: Pharmaceutical companies have boosted vaccine production following the global COVID-19 pandemic. In Côte d’Ivoire, the first vaccination campaign with the AstraZeneca vaccine began on March 1, 2021, as part of the Covax program. Despite the positive benefit/risk balance, the adverse effects of vaccination should not be minimized. Objective: To identify adverse events of AstraZeneca’s COVID-19 vaccination for better management. Materials and Methods: This is a case of a 57-year-old obese (BMI = 39 kg/m2) female health care worker who experienced adverse events in March 2021 after the second dose of AstraZeneca vaccine administered 4 weeks apart. These were subject to mandatory case reporting. Results: Major post-vaccination events occurred in a noisy systemic picture with parameters showing significant disturbances. Biological surveillance remains costly and makes the accountability of the vaccine complex. Conclusion: Vaccination remains the ultimate weapon in the fight against endemic diseases but should not overshadow the reporting of adverse events.

Occurrence of Extreme Rainfall and Flood Risks in Yopougon, Abidjan, Southeast Côte d’Ivoire from 1971 to 2022

Yopougon, located in the western part of the Autonomous District of Abidjan, is the most heavily populated municipality in Côte d’Ivoire. However, this area is prone to floods and landslides during the rainy season. The study aims to assess recent flood risks in the municipality of Yopougon of the Autonomous District of Abidjan. To achieve this objective, the study analyzed two types of data: daily rainfall from 1971 to 2022 and parameters derived from a Numerical Field and Altitude Model (NFAM). The study examined six rainfall parameters using statistical analysis and combined land use maps obtained from the NFAM of Yopougon. The results indicated that, in 67% of cases, extreme rainfall occurred mainly between week 3 of May and week 1 of July. The peak of extreme rainfall was observed in week 2 of June with 15% of cases. These are critical periods of flood risks in the Autonomous District of Abidjan, especially in Yopougon. In addition, there was variability of rainfall parameters in the Autonomous District of Abidjan. This was characterized by a drop of annual and seasonal rainfall, and an increase of numbers of rainy days. Flood risks in Yopougon are, therefore, due to the regular occurrence of rainy events. Recent floods in Yopougon were caused by normal rains ranging from 55 millimeters (mm) to 153 mm with a return period of less than five years. Abnormal heavy rains of a case study on June 20-21, 2022 in Yopougon were detected by outputs global climate models. Areas of very high risk of flood covered 18% of Yopougon, while 31% were at high risk. Climate information from this study can assist authorities to take in advance adaptation and management measures.

Prevalence of Ventilatory Function Abnormalities in Residents of Attecoube Lagune, Abidjan (Côte d’Ivoire)

Introduction: Studies of abnormal ventilatory function in Côte d’Ivoire have been carried out in the workplace and in schools. The objective of this study was to determine the prevalence of respiratory symptoms and ventilatory function abnormalities in the population of the lagoon district of Attécoubé in Abidjan. Material and Methods: A cross-sectional study was carried out on 170 people in the municipality of Attécoubé Lagune. A questionnaire was used to collect information on sociodemographic, clinical, and environmental characteristics. A basic spirometry and a beta mimetic test were carried out on all the subjects surveyed. Data analysis was done with the stata 15.1 software. Results: The study population was composed of 103 women and 67 men with a sex ratio (M/F) of 0.65. The average age was 35.92 ± 15.28 years. The most frequent respiratory symptoms were chest tightness (29.41%), dyspnea (28.82%), sneezing (22.94%) and cough (22.35%). The prevalence of ventilatory function abnormalities was 43.24% among residents of Attécoubé Lagune and the most frequent abnormality was ventilatory restriction (35.15%) followed by obstruction (4.85%). The risk factor for ventilatory function abnormalities was heavy pollution [OR = 2.66;IC: 1.053 - 6.743;P = 0.038]. Conclusion: Residents of the Attécoubé Lagune district had many respiratory symptoms and a high prevalence of ventilatory function abnormalities. Improving air quality is urgently needed in this municipality.

Epidemiological and Clinical Aspects of Hospitalized Patients with Chronic Rheumatic Disease at Cocody University Hospital in Abidjan

Objective: To study the epidemiological and diagnostic features of chronic rheumatic disease (CRD) in a black population in sub-Saharan Africa. Patients and Methods: Retrospective descriptive study over eight years (January 2005 to December 2012) of patients seen for CRD in rheumatology hospitalization at the CHU de Cocody in Abidjan, Côte d’Ivoire. Results: Of 3147 hospitalized patients, 92 had CRD, a frequency of 2.9%. The mean age of patients was 43.50 ± 15.6 years (extremes: 10 to 79 years). The sex ratio was 0.08 (7 men and 85 women). The socio-economic level was low in 44 patients (47.8%), medium in 44 patients (47.8%), and high in 4 patients (4.4%). The reasons for consultation were polyarthritis (64.1%), polyarthralgia (30.4%), and oligoarthritis (5.4%). The mean duration of symptomatology was 19 months (range: 3 to 20 years). The mean length of hospital stay was 14.2 ± 7.7 days (range: 2 to 36 days). The CRD observed were: rheumatoid arthritis (59.8%), systemic lupus erythematosus (23.9%), mixed connective tissue disease (6.5%), undifferentiated connective tissue disease (3.3%), polymyositis (3.3%), systemic scleroderma (2.2%), and systemic vasculitis (1%). Conclusion: CRD is not uncommon in rheumatology hospitals in Abidjan. Diagnostic delays are long, and rheumatoid arthritis and systemic lupus erythematosus are the most frequently encountered conditions.

Public Effective Dose Assessment Using Gross Alpha and Beta Radioactivity Levels of Tap Drinking Water in the District of Abidjan, Cote d’Ivoire

In order to assess public effective dose due to gross alpha and beta in water, 43 tap water samples were collected from different areas in the District of Abidjan. Using the low background Gas-less Automatic Alpha/Beta counting system (Canberra iMaticTM) for analysis, the gross alpha and beta concentrations found varied from 0.001 ± 0.002 to 0.063 ± 0.050 Bq/l with an average of 0.013 ± 0.012 Bq/l and from 0.067 ± 0.080 to 0.320 ± 0.120 Bq/l with an average of 0.174 ± 0.076 Bq/l, respectively in samples. The public effective dose assessment showed values of dose to ingestion of alpha and beta emitter radionuclides lower than the recommended value of dose for drinking water 0.1 mSv/y, except in 30% of the samples. These results show the need for additional studies to be conducted in order to clarify the hazardousness of these water samples. However, this study still remains important because it has provided necessary data for future tap water quality monitoring studies in the District of Abidjan.

Assessment of Anxiety among Caregivers at the Covid-19 Treatment Centers in Grand-Bassam and Cocody-Abidjan from July to September 2020

The rapid spread of coronavirus disease (COVID-19) has led to general psychosis among the population in Ivory Coast. The medical profession, on the front line of the treatment, was in distress, given the risk of exposure to the patient. It is in this context that this study has set itself the objective of studying anxiety among caregivers involved in the management of people with COVID-19. This is a cross-sectional, descriptive and analytical study that included a sample of 50 stakeholders. It took place from July to September 2020 at the Treatment Center of the Village of Information Technologies and Biotechnology in Grand-Bassam (VITIB) and the Infectious Diseases Treatment Center (CTMI) of the University Hospital (CHU) of Cocody. The results indicate that caregivers were male in 52% of cases with an average age of 36 years. These are: doctors, nurses and caregivers respectively in the proportions of 18%, 42% and 40% with more than half (58%) who had more than 5 years of seniority. A proportion of 34% of caregivers felt they were insufficiently protected. The Hamilton Scale assessment of anxiety showed that 14% had mild anxiety, 6% moderate anxiety and 2% severe anxiety. There was no link between the degree of anxiety and professional seniority but also between the degree of anxiety and the marital situation. This work has therefore made it possible to see that anxiety is a real problem for caregivers dedicated to the management of COVID-19 patients.

Study of the Akouedo Landfill (Abidjan) Using the Electrical Resistivity Method: Implications for the Risk of Contamination of the Continental Terminal Water Table

An electrical resistivity survey was carried out on the household and industrial waste disposal site (landfill) of Akouédo (Central Abidjan) with a view to searching for a possible layer of clay in the stratification which could constitute a protective screen of the aquifer of the Continental Terminal of Abidjan against the migration of leachate. Electrical surveys (SE) carried out according to the Schlumberger configuration showed that the stratigraphy of the area is composed of three to four geoelectric layers depending on the SE positions. The correlation with the lithology of two piezometric boreholes carried out indicates that the lithology of the study area is dominated by clayey sand, sand, sandy clay and clay. The average thickness of accumulated waste varies between 30 and 40 m. The virtual absence of a continuous layer of clay under the waste exposes the Continental Terminal aquifer to contamination by leachate from waste accumulated over several decades in the Akouedo area.

Evidence of the Albo-Cenomanian Unconformity Using Chemical Elements Case Study of Sediments from the Eastern Abidjan Margin

Sedimentological and chemostratigraphical studies using accessory elements on 322 samples of cuttings from oil wells located in the submerged sedimentary basin (offshore) of Côte d’Ivoire. This basin covered the chronostratigraphic interval from the Upper Albian to the top of the Maastrichtian. The aim of this study was to determine the major accident, the Albo-Cenomanian unconformity, using chemical elements. To achieve this goal, we had to count the accessory elements glauconite, pyrite and carbonaceous debris, and identify all the chemical elements present in each cuttings sample. The results clearly indicate that: the sediments are essentially composed of carbonaceous debris and pyrite, with a high potassium content for sediments dating from the Abian period;and glauconite, carbonaceous debris, pyrite, and a sharp decrease in potassium content for sediments dating from the Cenomanian to the Maastrichtian period. Threshold values for ratios of source-indicating chemical elements (Zr, Ti, Y, Th) and paleoenvironmental elements (K, Rb, Mg, Al,) highlighted the MS1 and MS2 mega-sequences in the study area. The difference observed in the threshold values of these ratios can be explained by changes in sedimentary dynamics. The depositional environment varies from an inner continental shelf with strong littoral influence (Upper Albian) to an increasing subsidence outer continental shelf (Cenomanian-K/Pg boundary).

Epidemiological Profile of Obesity among Adults Aged 21 to 65 Years Living in Yopougon, Cocody and Abobo (District of Abidjan, Côte d’Ivoire)

Objective: The study aims to establish the epidemiological profile of obesity in Abidjan. Methods: It was a cross-sectional study carried out in Côte d’Ivoire with 349 volunteers aged 21 to 65 years old and living in 330 households located in Yopougon, Cocody and Abobo, three Municipalities in the city of Abidjan. Results: Out of 349 participants, 90 or 25.8% were declared obese according to BMI. Based on IMG, 62.8% of people had abnormally high body fat. Abdominal obesity was more common in Yopougon and Cocody than in Abobo. Relative to BMI, 36.1% of women were obese compared to 12.9% of men. The same observation was made with regard to the umbilical perimeter. Indeed, abdominal obesity was more observed in women with a rate of 52.6% compared to 11.6% in men. 35.6% of obese people have no level of education. According to the respondents, a very high proportion of weight gain occurred after the age of 10. It was between 10 and 21 years old in Yopougon and Cocody and between 18 and 21 years old in Abobo. More than 70% of obese people living in Yopougon, Cocody and Abobo would not consider obesity as a disease while 40.7% have said they were very little informed about obesity. Conclusion: Two major points have emerged from the examination of the data collected: 1) The prevalence of overweight and obesity remains very high in the three Communes of Abidjan. 2) The occurrence of obesity would be influenced by the sociodemographic characteristics of the populations. Also, updating these sociodemographic characteristics is essential to better adapt national strategies for obesity and overweight combating.

Systemic Form of Juvenile Idiopathic Arthritis: Epidemiological, Clinical, Paraclinical and Therapeutic Aspects of 13 Cases in Abidjan

Objective: To describe the epidemiological, clinical, paraclinical and therapeutic aspects of systemic juvenile idiopathic arthritis observed in Abidjan. Materials and Method: This retrospective and descriptive study covered 13 children suffering from systemic juvenile idiopathic arthritis selected in the Rheumatology Department of University Hospital Center of Cocody in Abidjan (Cote d’Ivoire) from January 2005 to December 2015. We were interested to the sociodemographical, clinical, paraclinical and therapeutic aspects. Results: The systemic form of the juvenile idiopathic arthritis represented 0.2% of the 4608 rheumatologic diseases and 70.58% of the JIA. We selected 6 boys and 7 girls, with an average age of 10.8 years and mostly going to school (84.61%). The diagnostic delay was 18 months. The main clinical signs were fever and joint damage observed each in 100% of cases, impaired general condition (92.30%) and tumor syndrome (83.33%). Biological signs were characterized by hyperleukocytosis (69.20%) and the presence of a biologic inflammatory syndrome (on average, erythrocyte sedimentation rate 59.6 mm and C Reactive Protein 56.4 mg/l). The cervical damage was the essential functional complication (38.46%). The major treatment has been a therapeutic combination based on corticotherapy and methotrexate (100%) with 1 death case by macrophage activation syndrome. Conclusion: Systemic juvenile idiopathic arthritis is rarely diagnosed in the rheumatologic practice in Abidjan. It concerns children relatively big, and is characterized by a febrile polyarthritis with impaired general condition and tumor syndrome. This systemic form is treated by corticotherapy and methotrexate.

Heavy Metal Fluxes in Tropical Urban Forest Soil in Abidjan District (Côte d’Ivoire)

In Western Africa, the growth of cities has led to natural resource pollution, especially air pollution. Urban forests play a key role in filtering atmospheric particles and pollutants through the canopy before reaching the soil. This study aims to quantify heavy metal fluxes in an urban forest in the district of Abidjan in order to assess its role in the protection of natural resources. A monitoring of wet deposition (throughfall and open field rain) and litterfall was carried out for six months in the urban forest of the National Floristic Center located in Abidjan, C?te d’Ivoire. The results show that the soil of this urban forest is a ferralsol type characterized by a sandy-clay texture and a low load of coarse elements. The annual litterfall is estimated to 12.16 ± 0.71 t·ha-1·yr-1, similar to other tropical forests. Annual quantities of rain and throughfall are in the range of the rainfall recorded in the district of Abidjan (2013 ± 152 and 1773 ± 51 mm). Chemical analyses showed that litter and rainfall contain Mn, Zn, Ni, Cr, Cd and Hg. Manganese and Zn are the most abundant elements and Hg the least abundant in both rainfall and litter. The main source of input of the heavy metals into the urban forest soil is associated with biological recycling through the litter. The litterfall contributes to metal fluxes in soil 109 times greater than metal fluxes carry by wet depositions (open field rain and throughfall). However, a detailed study of rainfall showed that the forest canopy constitutes a barrier for the transfer of heavy metal to urban soil. This is indicated by a decrease in heavy metal content from open field rain to throughfall. Consequently, this study recommends the creation and maintenance of urban forests to increase biomass canopy and improve atmospheric air quality for West African cities undergoing constant change and development.

Assessment of Regular Physical Activity in the Care of Hypertensive Patients at the Cardiology Institute of Abidjan and at the National Police Hospital (Ivory Coast)

Aim: Physical activity and other lifestyle changes are an important part of the guidelines for anti-hypertensive therapy. The effect of physical activity on hypertension and heart disease has been well described. No study in our context has been done on this issue. The aim of this study was to evaluate regular physical activity in the management of hypertensive patients at the Cardiology Institute of Abidjan and the National Police Hospital. Material and methods: This was a prospective and descriptive study held in the External Consultations and Rehabilitation Departments of the aforementioned structures. It started on July 20, 2017 and ended on September 7, 2017. The data were analyzed on SPSS version 22. A p-value of less than 0.05 was considered to be statistically significant. Results: Out of the 190 hypertensive patients recruited and educated, only 70 actually participated in the physical activities that took place in the Rehabilitation Department of Heart Institute. The mean age of the patients was 52 years ± 15 years. The most affected age group was between 40 and 49 years of age (47.40%).There was a male predominance with a sex ratio of 1.11. 63.16% of the patients had a superior. The follow-up time for Hypertension was more than one year in 73.68% of the cases. Our study highlighted the knowledge of the virtues of regular physical activity on the body in 94.74% of cases. Physical activity was prescribed in 94.74% of cases. It was practiced in 63.16% of cases. The mains reasons given for those who did not practice physical activity were “lack of willpower” (90%) and physical activity considered “too tiring” (70%). Physically active patients had a significant decrease of 17.98 mmHg in systolic blood pressure (p < 0.001) and 11.54 mmHg in diastolic blood pressure (p < 0.001). Conclusion: The practice of physical activity in the control of hypertension remains insufficient at the Abidjan Heart Institute. Despite this insufficiency, physical exercise seems to have a positive effect on blood pressure control associated with antihypertensive pharmacological treatment.

Upper Gastrointestinal Endoscopy and Children Digestive Pathology in Abidjan

The aim of our study is to determine the demographic data, indications, performance, and security of gastroscopy in children in Ivory Coast. Patients and Methods: This is a retrospective analytical study based on reports of upper digestive endoscopy per-formed in children (from 1 day to 15 years included) in 2 university hospitals in Abid-jan from March 2009 to March 2016. Results: 276 upper gastrointestinal endoscopies (UGIE) were performed in children during the study period. UGIE was performed with a diagnostic purpose in most cases (99%). The indications of UGIE were abdominal pains (38.95%), ingestion of caustic substances (29.82%), upper gastrointestinal bleeding (10.87%) and vomiting (10.17%). UGIE was normal in 39.49% of cases for all ages. The main anomalies observed in upper gastrointestinal (GI) endoscopy for all ages were gastropathies (29%);caustic lesions (13.02%) and bile reflux (10.45%). Ul-cers were rarely found (2.54%). Histological examination of biopsies revealed chronic H. pylori gastritis in 67% of gastric samples examined. All endoscopic examinations were performed without incident. Conclusion: Gastroscopy is a harmless examination with a great diagnostic and therapeutic utility in digestive pathology of children in Ivory Coast.

Sensitivity of Solar Photovoltaic Panel Efficiency to Weather and Dust over West Africa: Comparative Experimental Study between Niamey (Niger) and Abidjan (Côte d’Ivoire)

Energy demand is increasing while we are facing a depletion of fossils fuels, the main source of energy production in the world. These last years, photovoltaic (PV) system technologies are growing rapidly among alternative sources of energy to contribute to mitigation of climate change. However, PV system efficiency researches operating under West African weather conditions are nascent. The first objective of this study is to investigate the sensitivity of common monocrystalline PV efficiency to local meteorological parameters (temperature, humidity, solar radiation) in two contrasted cities over West Africa: Niamey (Niger) in a Sahelian arid area and Abidjan (Cote d’Ivoire) in atropical humid area. The second objective is to quantify the effect of dust accumulation on PV efficiency in Niamey (Niger). The preliminary results show that PV efficiency is more sensitive to high temperature change especially under Niamey climate conditions (warmer than Abidjan) where high ambient temperatures above 33°C lead to an important decrease of PV efficiency. Increase of relative humidity induces a decrease of PV efficiency in both areas (Niamey and Abidjan). A power loss up to 12.46% is observed in Niamey after 21 days of dust accumulation.

Potential Groundwater Pollution Risks by Heavy Metals from Agricultural Soil in Songon Area(Abidjan,Cote d’Ivoire)

The soil samples were collected taking into account the land use in Songon area. The hydraulic conductivity (K) of soils was characterized in-situ when specific yield (Sy), pHw and concentrations of Cooper, Iron, Zinc, Cadmium, Chromium and Lead were measured in the laboratory. Pollution load indices (PLI) were calculated to evaluate the soil contamination levels. The soils were neutral and alkaline (6.7≤ pH ≤ 9.20), permeable (1.9 í 10-5?m·s-1?≤ K ≤ 8.2 í 10-4?m·s-1), with a high specific yield (13.33% ≤ Sy ≤ 33.33%) which can favor the pollutants transfer. The heavy metals (Fe, Cu, Zn, Cd, Cr and Pb) have very high concentrations in soils. The integrated pollution indices (PLI) indicate that almost 70% of Songon soils are moderately contaminated by the investigated heavy metals, with windows presenting high indices of pollution related to the intensive use of fertilizers and pesticides. The establishment of new boreholes in the Songon area should consider these heavy metals, so as to avoid the risk of groundwater pollution due to the physical properties of soils.

Using Water Quality Index for Assessing of Physicochemical Quality of Quaternary Groundwater in the Southern Part of Abidjan District (Côte d’Ivoire)

In this study, fourteen physicochemical parameters were monitored at 61 groundwater sampling points located in the southern part of Abidjan District. Each water sampling location was sampled in March and July 2007, representing respectively the long dry season and the long wet season. Groundwater evaluation index and statistical methods were used to assess Quaternary groundwater physicochemical quality in term of drinking and irrigation purposes. The groundwater samples irrespective of seasons fell in mixed K-Na-HCO3 and K-Na-Cl types. Groundwater quality index values varied from 14.01 to 593.44 and from 20.88 to 567.44, in dry and rainy seasons, respectively. In both seasons, 9.83% exhibited poor water quality and 3.27% indicated unsuitable water for drinking purposes. The studied water wells were heavily contaminated with nitrate, nitrite and ammonium in the strongly urbanized areas at Treichville, Koumassi, Marcory, Port-Bou?t and Grand-Bassam. The degree of correlation between physicochemical parameters suggested that groundwater quality was mainly related to geogenic (rock–water interaction) and anthropogenic sources (domestic sewage), and intrusion of marine and lagoon waters in the study area. Sodium adsorption ratio was generally low during study period, indicating most groundwater sampled was suitable for irrigation purposes.

Prevalence and Associated Risk Factors of Porcine Echinococcosis at the Ivorian Pig Slaughter Company (SIVAC), Yopougon Abidjan: A Cross Sectional Study

Background: Parasitic diseases are threat to the development of Ivorian Pig industry. Zoonotic diseases such as Echinococcosis have a significant impact on animal health and production. Little is known about Echinococcosis in Cô te d’Ivoire. Aim: For these reasons, a cross section study was conducted at SIVAC in Yopougon, on pigs (Sus scrofa domesticus), in order to determine the prevalence and associated risk factors of Echinococcosis. Method: Paraclinical examinations of pig organs (kidneys, lungs, and liver) were conducted from 5th September to 30th December 2019 in order to report infection with this parasite. Results: Out of the 2425 slaughtered pigs, 63 of them were Echi-nococcosis positive, resulting in overall infection prevalence of 2.6% (95% CI: 1.9% - 3.22%). The kidneys (2.35%) were most infected, followed by lungs (0.21%), and liver (0.04%). Recommendations: A more in-depth study on the molecular epidemiology of Echinococcosis in the different regions of Cô te d’Ivoire is underway. Also, capacity building of community livestock actors (Veterinarians, health inspectors, breeders and butchers) and sensitization of the population on this disease is necessary in order to improve its diagnosis at the abattoir level and to set up strategies to combat it.

Multilevel Cervicothoracic and Lumbar Pott’s Disease: About Three New and Unusual Cases in the Rheumatology Department of the Teaching Hospital of Cocody in Abidjan (Côte d’Ivoire)

Pott’s disease usually affects two contiguous vertebrae or two spinal levels. The involvement of the three cervicothoracic and lumbar levels is rarely described. Only three cases have been described in the literature to our knowledge. The authors report three new cases of tuberculous spondylodiscitis of cervicothoracic and lumbar site. Our three cases were characterized by symptoms similar to the other topographical forms of Pott’s disease. A predisposing factor is often identified like the infection with human immunodeficiency virus. The definitive diagnosis was made in two cases by identifying acid and alcohol-fast bacilli for one case and by histology for the other case. For the third case, there was a diagnostic presumption reinforced by the satisfactory outcome on tuberculosis chemotherapy for a period of 12 months. The multilevel nature of diseases does not influence the effectiveness of treatment of this form of spinal tuberculosis.

Tuberculosis of the Sternoclavicular Joint: Report of 3 New Cases Observed in Abidjan

The sternoclavicular joint is a rare site of osteoarticular tuberculosis. We now report three new cases of sternoclavicular tuberculosis. The report concentrates mostly on immunocompromised patients, notably two with HIV infection and one case marked by its acute onset which is rather original because, in this case, there was a swollen sternoclavicular joint with normal X-ray and it was the CT-scan which showed the lesions. The etiological diagnosis was made in the first case by polymerase chain reaction and in the second case by identification of Mycobacterium tuberculosis. In the third case, the diagnosis was presumptive and the outcome on anti-tuberculous drugs was satisfactory. Sternoclavicular joint tuberculosis is unusual;the painful swelling of that joint should lead to realize a performed imaging such as CT-scan.
