Diagnostic accuracy of swine echinococcosis cytopathological tests and challenges for a differential diagnosis: slaughterhouse data.

Echinococcosis disease shows clinical signs similar to many diseases. Hence we report cases that need to be confirmed using appropriate tests. A confirmatory study has been conducted to assess the accuracy of two cytopathological tests, with the histopathology test as the reference standard. The first cytopathological test evaluates the Ziehl Neelsen staining with an epifluorescence microscope (cytopath 1). The second cytopathological test uses the same staining followed by a transmitted light microscope examination (cytopath 2). Of a total of 2524 inspected pigs, 101 suspected cases of echinococcosis were detected, of which 67 were found positive with the two cytopathological tests and the histopathological one. The specificity of cytopath 1 (100 % [95 % CI 100 - 100]) and cytopath 2 (100 % [95 % CI 100;100]) were similar, as well as their respective positive predictive values: 100 % [95 % CI 100 - 100] vs. 100 % [95 % CI 100 - 100]. The sensitivity of cytopath 1 is 79.66 % [95 % CI 69.39 - 89.93], while cytopath 2 equals 66.10 % [95 % CI 54.02 - 78.18]. The difference in sensitivity of both tests was not significant. Negative predictive values found for cytopath 1, and cytopath 2 were 40 [95 % CI 18.53 - 61.47] and 28.57 [95 % CI 11.84 - 45.3], leading to the Generalized Estimating Equations (GEE) Model estimate for an odds ratio of 1.4 [95 % CI 0.41 - 5.2], p = 0.06. Cytopath 1 and cytopath 2 are equivalent in terms of specificity (100 % [95 % CI 100 - 100] vs. 100 % [95 % CI 100;100]) and positive predictive value (100 % [95 % CI 100 - 100]. Cytopath 1 is more sensitive than cytopath 2 but not significant (79.66 % [ 95 % CI 69.39 - 89.93] vs. 66.10 % [95 % CI 54.02 - 78.18]). However, the negative predictive value of cytopath 1 is better than that of cytopath 2: 40 % [95 % CI 18.53 - 61.47] vs. 28.57 % [95 % CI 11.84 - 45.3].

[Our experience of the sural flap with distal pedicle in the repair of foot plantar and heel of foot lesions]. / Notre expérience du lambeau sural à pédicule distal dans la réparation des lésions du talon et de la plante du pied.

PURPOSE: The sural flap has often been used to cover the weight-bearing and non-weight-bearing areas of the foot and ankle. This study reports our experience in the coverage of these defects in the foot in weight-bearing areas. PATIENTS AND METHOD: This is a retrospective and descriptive study of 70 months. This study includes 16 patients presenting a loss of plantar substance and/or heel of the foot covered by a sural flap with a distal pedicle. The sampling technique described by Masquelet served as our reference. An increase in the length of the pedicle of at least two centimeters during the dissection made it possible to avoid any stretching or compression for the most distal lesions. RESULTS: The average age was 35 years with a sex ratio of three in favor of men. Traumatic lesions predominated (n=10) with an average area of lesions of 68.8cm2. The average partial and total support times were 1.8 and 3.6 months respectively. We noted one case of flap necrosis. The natural evolution of the flap took place in three progressive stages: regeneration, keratinization and squamous metaplasia. Normal bipodal support and stable gait without footwear anomaly were noted in 15 cases. CONCLUSION: The distal pedicle sural flap technique is accessible. Its reliability makes it an ideal choice for distal loss of substance to the leg and foot.

GAYET WERNICKE'S ENCEPHALOPATHY AFTER COVID-19 IN ELDERLY SUBJECTS IN TROPICAL ENVIRONMENTS: STUDY OF SIX (6) OBSERVATIONS IN CONAKRY.

In sub-Saharan Africa, the COVID-19 pandemic has caused severe malnutrition in elderly populations with the appearance of vitamin deficiencies, in particular thiamine responsible for Gayet Wernicke's encephalopathy (EGW). We present a series of six (6) patients hospitalized in the Neurology Department of the CHU Ignace Deen for the management of a brain syndrome with vigilance disorders after recovery from COVID-19, including oculomotor disorders, motor incoordination on a course of severe weight loss. The six patients underwent an evaluation of malnutrition by determining the WHO body mass index, the Detsky index, the serum albumin assay, the thiamine assay and a neuroradiological assessment (MRI) and an electroencephalogram (EEG) examination although this does not seem necessary for diagnosis. Study of nutritional status: weight loss greater than 5%, patients in Desky group B and C, plasma albumin<30 g/l, lowered thiamine and MRI neuroradiological data: by the existence of hypersignals in certain regions of the neocortex, certain gray nuclei, the mammillary bodies the thalamic nuclei close to the wall of the 3rd ventricle and the regions bordering the 4th ventricle sign Gayet Wernicke's encephalopathy syndrome. This study shows a stereotyped clinical, biological, neuroradiological and evolutionary profile of Gayet Wernicke's encephalopathy in elderly subjects recovered from Covid-19 with proven malnutrition. These results are useful for the therapeutic and prognostic discussion.

Risk factors associated with necrotizing fasciitis of the lower limbs: A multicenter case-control study.

OBJECTIVE: The aim of this case-control study was to identify risk factors associated with necrotizing fasciitis (NF) of the lower limbs. PATIENTS AND METHODS: We conducted a prospective case-control study in hospital dermatology departments in 5 sub-Saharan African countries over a 2-year period (April 2017 to July 2019). The cases were patients with NF of the lower limbs and the controls were patients with leg erysipelas. Each case was matched with two controls for age (±5 years) and sex. We analyzed local and general factors. RESULTS: During the study period, 159 cases (73 females, 86 males) were matched with 318 controls. The mean age was 48.5±15.8 years for cases and 46.5±16.2 years for controls (P=0.24). The main local signs of NF were cutaneous necrosis (83.7%), pain (75.5%) and induration (42.1%). Multivariate analysis showed the following to be independent risk factors associated with NF of the lower limbs: obesity (odds ratio [OR]=2.10; 95% confidence interval [CI]: 1.21-3.42), diabetes (OR=3.97; 95% CI: 1.95-6.13), nicotine addiction (OR=5.07; 95% CI: 2.20-11.70), use of non-steroidal anti-inflammatory drugs (NSAIDs) (OR=7.85; 95% CI 4.60-14.21) and voluntary cosmetic depigmentation (OR=2.29; 95% CI: 1.19-3.73). CONCLUSION: Our study documents the role of NSAID use at the onset of symptoms as a risk factor for NF of the lower limbs. However, the originality of our study consists in the identification of voluntary cosmetic depigmentation as a risk factor for NF of the lower limbs in sub-Saharan Africa patients. Our results also identified typical overarching factors such as diabetes, obesity and nicotine addiction. Knowing these factors and taking them into account will enable optimization of management strategies for these conditions.

Anxiety and depression among HIV patients of the infectious disease department of Conakry University Hospital in 2018.

Anxiety and depression continue to be significant comorbidities for people with human immunodeficiency virus (HIV) infection. The aim of this study was to determine the prevalence of anxiety and depression disorder among HIV patients at Conakry, Guinea. In this cross-sectional study, we described socio-demographic, clinical and psychosocial data related to anxiety and depression in 160 HIV patients of the University Teaching Hospital, Conakry, Guinea. The Hospital Anxiety and Depression Scale (HADS) was used for measuring depression and anxiety in the prior month. The HADS score of ⩾8 was used to identify possible cases of depression and anxiety. Multivariate logistic regression analyses were performed to identify factors associated with symptoms of anxiety and depression. The prevalence of comorbid depression and anxiety among HIV patients was 8.1% and the prevalence of anxiety and depressive symptoms among HIV-infected patients was 13.8% and 16.9%, respectively. Multivariate analysis showed that individuals having BMI ⩽ 18 (AOR = 3.62, 95% confidence interval (CI) 1.37-9.57) and who did not receive antiretroviral treatment (AOR = 18.93, 95% CI 1.88-188.81) were significantly more likely to have depressive symptoms. Similarly, having age <40 years (AOR = 2.81, 95% CI 1.04-7.58) was also significantly associated with anxiety. Prevalence of symptoms of anxiety and depression was high in these HIV patients. This suggests a need for training on the screening and management of anxiety and depression among HIV patients.

2,5-diketopiperazines mitigate the amount of advanced glycation end products accumulated with age in human dermal fibroblasts.

OBJECTIVE: Glycation is a common non-enzymatic reaction between proteins and sugars, resulting in the formation of advanced glycation end products (AGEs) in the human body. As can be seen in diabetic patients, the accumulation of AGEs in the skin has aesthetic consequences (wrinkles, brown spots and yellowish complexion). Therefore, the objective of this work was to find compounds isolated from natural sources that could eliminate the final AGEs accumulated in the skin with ageing. METHODS AND RESULTS: A preliminary screening performed on a bank of microbial extracts and pure compounds showed that 2,5-Diketopiperazines (DKPs), as well as the extract of Sphingobacterium sp (SNB-CN13), reduced the presence of AGEs in fibroblasts by -28% and -23%, respectively. In this article, we present the dereplication approach used to reveal the presence of 26 different DKPs in the crude extract of Sphingobacterium sp. Bioguided fractionation has led to the isolation of 12 of them, whose identity has been confirmed by HRMS and NMR. A green synthesis approach has been developed to synthesize 3 symmetrical DKPs. The biological activity of all DKPs was evaluated by the development of an in vitro test using immunocytochemistry to reveal the presence of AGE carboxymethyl-lysine in human dermal fibroblasts. CONCLUSION: Our work shows for the first time that DKPs decrease the amount of carboxymethyl-lysine AGE in elderly human dermal fibroblasts grown in vitro. Therefore, diketopiperazines can be considered as compounds of interest for dermatological and cosmetic applications with an anti-ageing aim.

OBJECTIF: La glycation est une réaction non enzymatique courante entre les protéines et les sucres, qui entraîne la formation de produits finaux de glycation avancée (AGE) dans le corps humain. Comme on peut le voir chez les patients diabétiques, l'accumulation d'AGE dans la peau a des conséquences esthétiques (rides, taches brunes, teint jaunâtre). Par conséquent, l'objectif de ce travail était de trouver des composés isolés de sources naturelles qui pourraient éliminer les AGE finaux accumulés dans la peau avec le vieillissement. MÉTHODES & RÉSULTATS: Un examen préliminaire effectué sur une banque d'extraits microbiens et de composés purs a montré que les 2,5-dicétopipérazines (DKP), ainsi que l'extrait de Sphingobacterium sp. (SNB-CN13), réduisaient la présence d'AGE dans les fibroblastes de - 28% et - 23% respectivement. Dans cet article, nous présentons l'approche de déréplication utilisée pour révéler la présence de 26 DKP différentes dans l'extrait brut de Sphingobacterium sp. Le fractionnement bioguidé a conduit à l'isolement de 12 d'entre elles, dont l'identité a été confirmée par HRMS et RMN. Une approche de synthèse verte a été développée pour synthétiser 3 DKP symétriques. L'activité biologique de toutes les DKP a été évaluée par le développement d'un test in vitro utilisant l'immunocytochimie pour révéler la présence de carboxyméthyl-lysine AGE dans les fibroblastes dermiques humains. CONCLUSION: Nos travaux montrent pour la première fois que les DKP diminuent la quantité de carboxyméthyl-lysine AGE dans les fibroblastes dermiques humains âgés cultivés in vitro. Par conséquent, les dicétopipérazines peuvent être considérées comme des composés intéressants pour des applications dermatologiques et cosmétiques à visée anti-âge.

[Risk factors associated with acne keloidalis nuchae, in black subjects: A case-control study]. / Facteurs de risque associés aux folliculites fibrosantes de la nuque chez le sujet noir : étude cas-témoins.

OBJECTIVE: The aim of this case-control study was to identify risk factors associated with acne keloidalis nuchae (AKN), seen in a dermatology clinic in Lomé (Togo). PATIENTS AND METHODS: This was a case-control study conducted from January to December 2018. Patients were recruited at outpatients dermatological clinics and controls were recruited at outpatients dermatological clinics and then in other hospital departments. RESULTS: We recruited 303 consenting subjects, comprising 101 patients with AKN and 202 controls case-matched by age (±5 years). The mean patient age was 34.9±10.7 years vs. 35.6±11.2 years for controls. The most frequently observed AKN lesions were papules (73/101; 72.2%), fibrous scars (42/101; 41.5%) and folliculitis/pustules (41/101; 40.6%). In multivariate analysis, the following factors were associated with AKN: excess weight (adjusted odds ratio=4.8; 95% CI=[2.3-11.7]) or obesity (OR=9.2; 95% CI=[2.1-34.2]), bleeding during hairdressing either occasionally (aOR=13.9; 95% CI=[5.1-40.0]) or systematically (aOR=22.1; 95% CI=[6.2-40.7]), hairdressing procedures less than once per week (aOR=10.1; 95% CI=[3.2-50.8]), and extremely close cropping of hair (aOR=4.9; 95% CI=[2.8-15.5]). CONCLUSION: AKN is common in young adults. Excess weight or obesity, bleeding during hairdressing, and frequency and style of hairdressing are all associated factors. The results of this study stress the importance of limiting injury during hairdressing, and of refraining from shaving or cropping hair without a trimmer. Since management of AKN is extremely difficult, identification of associated risk factors allows suitable preventive approaches to be adopted.

Effect of Environmental Factors on Nuclear Organization and Transformation of Human B Lymphocytes.

Chromosomal translocations have long been known for their association with malignant transformation, particularly in hematopoietic disorders such as B-cell lymphomas. In addition to the physiological process of maturation, which creates double strand breaks in immunoglobulin gene loci, environmental factors including the Epstein-Barr and human immunodeficiency viruses, malaria-causing parasites (Plasmodium falciparum), and plant components (Euphorbia tirucalli latex) can trigger a reorganization of the nuclear architecture and DNA damage that together will facilitate the occurrence of deleterious chromosomal rearrangements.

[Knowledge, attitudes and practices of healthcare providers on suspected Ebola cases in Guinea]. / Connaissances, attitudes et pratiques des prestataires de soins de santé de face aux cas suspects d'Ebola en Guinée.

BACKGROUND: Developing a more resilient health system to Ebola Virus Disease (EVD) is a necessity in Guinea. This implies having information on the knowledge and practices that health staffs had during the preceding the EVD outbreak. The objective of this study was to compare the knowledge, attitudes and practices of routine healthcare providers on suspected EVD cases in the affected and non-affected districts in Guinea. METHODS: A cross-sectional analytic study was conducted from December 6th to 30th, 2014 with health staffs and community health workers from 120 health facilities, in four health districts more affected by the EVD and four others less affected. RESULTS: Health staffs who declared being able to identify a suspected EVD case were represented more in the more affected districts (95.2%) than in the less affected districts (78.7%, P<0.01). The main practice towards a suspected case in the more affected districts was referral to the Ebola treatment centre (79.2%, versus 20% in the less affected districts, P<0.05), while in the less affected districts, cases were first tested for malaria prior to treatment or referral (3 cases out of 5). Community health workers who declared being able to identify a suspected EVD case were significantly more represented in the more affected districts (73%) than in the less affected districts (38.1%, P<0.001). CONCLUSION: This study suggests that health system managers should prioritize capacity building of health providers in EVD affected as well as in non-affected districts to ensure better preparation for and response to EVD outbreaks.

[Factors associated to loss of follow-up in patients underwent antiretroviral therapy in an ambulatory HIV treatment center at Conakry]. / Facteurs associés aux perdus de vue des patients sous traitement antirétroviral dans un centre de traitement ambulatoire du VIH à Conakry, Guinée.

BACKGROUND: Late or inadequate therapeutic management increases the risk of mortality associated with HIV/AIDS. The aim of this study was to analyze the proportion and factors associated with loss of follow-up in HIV patients who receiving antiretroviral therapy at Conakry. METHODS: A retrospective cohort study was conducted in HIV patients aged over 15 years and who receiving antiretroviral therapy. Between August 1, 2008 and July 31, 2015, all patients managed by the ambulatory treatment center of the Guinean Women Association against AIDS and sexually and transmissible infection were included. Loss of follow-up was defined as no follow-up visit within 3 months. Kaplan-Meier curves and multivariate Cox regression models were used to analyze factors associated with loss of follow-up. Analyses were performed by using Stata 13 software. RESULTS: 614 patients aged 36.3±11.2 years, mainly females (68.4%) and living in Conakry (80.5%) were included. Among them, 104 were loss to follow-up, corresponding to a proportion rate of 16.9% (95% CI: 14.2-19.7%) or 5.79/100 person-years. The results of multivariate analyses showed that factors independently associated with loss of follow-up were malnutrition (AHR=7.05; 95% CI: 2.05-24.27; P=0.002) and CD4 cells account at the initiation of AHR (2.35; 95% CI: 1.61-6.39; P=0.016) in patients with 201-350 CD4/µL and 5.83 (95% CI: 2.85-11.90; P<0.001) in patients with less than 150CD4/µL. CONCLUSION: Despite efforts of health care workers and free antiretroviral therapy, many patients were loss to follow-up. Multivariate analysis showed that malnutrition and low CD4 account were independently associated with loss to follow-up.

Non-nucleoside reverse transcriptase inhibitors (NNRTIs)-induced Stevens-Johnson syndrome and gynecomastia in an HIV-infected child: A case report.

BACKGROUND: Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are antiretroviral drugs often used in the first-line treatment regimen of HIV1 infection worldwide. We report a case of successive gynecomastia and Stevens-Johnson syndrome (SJS) respectively induced by efavirenz and nevirapine in a single patient. CASE REPORT: A 16-year-old boy, HIV1-infected since birth, was started on antiretroviral treatment (ART) in August 2015 and was taking a regimen comprising abacavir, lamivudine and efavirenz. In April 2016, when his weight reached 35kg, abacavir was replaced with tenofovir. Bilateral breast enlargement, previously hidden by the patient, was diagnosed two years after the start of ART. History-taking, physical examination and laboratory tests ruled out known causes of gynecomastia, and efavirenz was thus considered the most likely cause. This drug was then withdrawn and replaced with nevirapine in July 2017. Thirty-three days after the patient started nevirapine treatment, a skin rash appeared. Physical examination revealed erythematous macules and flaccid bullae with estimated skin detachment of 10%. There were also conjunctival, buccal and genital lesions. A diagnosis was made of SJS induced by nevirapine. Three months after withdrawal of efavirenz, breast size decreased by 3cm on the left breast and 2cm on the right breast; two months after the SJS, cutaneous sequelae alone persisted, such as diffuse hyperchromic macules. DISCUSSION: Recognition of gynecomastia as a side-effect of efavirenz is important to allow the condition to be treated while it is still potentially reversible. Moreover, when efavirenz is replaced, a protease inhibitor should be preferred to nevirapine.

[Factors associated with the severity of acute ocular involvement in Stevens-Johnson syndrome and toxic epidermal necrolysis in sub-Saharan Africa]. / Facteurs de risque associés à la sévérité de l'atteinte oculaire au stade aigu du syndrome de Stevens-Johnson et de la nécrolyse épidermique toxique en Afrique subsaharienne.

AIM: The purpose of this study was to identify risk factors associated with the severity of acute ocular involvement in Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) in sub-Saharan Africa. PATIENTS AND METHOD: A retrospective study was carried out at the dermatology department in collaboration with the ophthalmology department for SJS/TEN patients between January 2000 and December 2016 in Lomé (Togo). The severity of acute ocular involvement was evaluated using the Power classification, and the drug eruption score was assessed using de Bastuji-Garin classification. RESULTS: A total of 107 cases of SJS/TEN (84 cases of SJS, 20 cases of TEN and 3 cases of overlap syndrome) were analyzed. There were 71 women and 36 men, with an average age of 32.3±12.5 years (range: 5 to 75 years). Sulfonamides (37.4%) were the most commonly used drugs followed by nevirapine (22.4%). HIV serology was positive in 46 (58.2%) of the 79 patients tested. A total of 54 (50.5%) patients had acute ocular involvement, which was mild in 29.9% of patients, moderate in 13.1% and severe in 7.5%. In multivariate analysis, exposure to sulfadoxine was the sole factor associated with moderate or severe acute ocular involvement in SJS/TEN (adjusted odds ratio=3.3; 95% CI=[1.1; 10.2]). CONCLUSION: Exposure to sulfadoxine was identified in our study as a risk factor associated with the severity of acute ocular involvement in SJS/TEN. Multicenter studies should be conducted in sub-Saharan Africa to confirm this associated risk factor.

Genetic abnormalities leading to qualitative defects of sperm morphology or function.

Infertility, defined by the inability of conceiving a child after 1 year is estimated to concern approximately 50 million couples worldwide. As the male gamete is readily accessible and can be studied by a simple spermogram it is easier to subcategorize male than female infertility. Subjects with a specific sperm phenotype are more likely to have a common origin thus facilitating the search for causal factors. Male infertility is believed to be often multifactorial and caused by both genetic and extrinsic factors, but severe cases of male infertility are likely to have a predominant genetic etiology. Patients presenting with a monomorphic teratozoospermia such as globozoospermia or macrospermia with more than 85% of the spermatozoa presenting this specific abnormality have been analyzed permitting to identify several key genes for spermatogenesis such as AURKC and DPY19L2. The study of patients with other specific sperm anomalies such as severe alteration of sperm motility, in particular multiple morphological anomalies of the sperm flagella (MMAF) or sperm unability to fertilize the oocyte (oocyte activation failure syndrome) has also enable the identification of new infertility genes. Here we review the recent works describing the identification and characterization of gene defects having a direct qualitative effect on sperm morphology or function.

Single gene defects leading to sperm quantitative anomalies.

Azoospermia, defined by the absence of sperm in the ejaculate, is estimated to affect up to 1% of men in the general population. Assisted reproductive technologies have revolutionized the treatment of infertility, and some azoospermic men, those with a post-meiotic defect, can conceive following the use of viable spermatoza recovered from testicular or epididymal biopsies. Although male infertility is a multifactorial disease, it is believed that genetic factors are predominant in the etiology of azoospermia and severe oligozoospermia. Despite that assumption, substantiated by the high number of infertile knockout (KO) mice and the even higher number of genes expressed essentially in the testis, little is known about the pathophysiology of reduced sperm production, its primary causes or the genetic and epigenetic consequences for the gamete and the future conceptus. The identification of genetic abnormalities is therefore paramount to understand spermatogenesis, to adopt the best course of action for the patient and to provide adequate genetic counseling. We provide here a review of the recent literature on the genetics of azoospermia and oligozoospermia, focusing on defects directly altering sperm production. New sequencing technologies are contributing to the rapid evolution of the recent field of infertility genetics.

[Treatment outcome, survival and their risk factors among new tuberculosis patients co-infected with HIV during the Ebola outbreak in Conakry]. / L'issue du traitement, la survie et ses facteurs de risque chez les nouveaux tuberculeux co-infectés par le VIH pendant l'épidémie d'Ebola à Conakry.

BACKGROUND: Mortality among TB/HIV co-infected patients remains high in Africa. The study aimed to estimate survival and associated factors in a cohort of TB/HIV co-infected patients who started tuberculosis treatment during the Ebola outbreak in Conakry, Guinea. METHODS: A prospective cohort study was conducted from April 2014 to December 2015. TB patients with HIV co-infection were enrolled at the University Hospital of Conakry. Survival and risk factors were analyzed according to Kaplan-Meier's method, log-rank test and Cox's regression. RESULTS: Data from 573 patients were analyzed. From these, 86 (15.0%) died before the end of treatment, 52% occurring within eight weeks of treatment onset. Survival at 4, 12 and 24 weeks after the beginning of the TB treatment was 92%, 86% and 83%, respectively. Independent risk factors associated with death were in the cell CD4 <200 cells/mm3 [adjusted hazard ratio (AHR): 2.25; 95% CI (confidence intervals): 1.16-4.37], opportunistic infections other than TB [AHR: 2.89; 95% CI: 1.39-6.02], and comorbidities [AHR: 4.12; 95% CI: 2.10-8.10]. An increase of one unit in hemoglobin [AHR: 0.81; 95% CI: 0.75-0.91] was protective of death. CONCLUSION: TB/HIV co-infected patients had a higher fatality rate during treatment of tuberculosis. Prevention of opportunistic infections, anemia and proper management of tuberculosis treatment in early comorbidities may improve survival for TB/HIV co-infected patients in restoring immune function.

[Immediate full removable dentures. A clinical reality of oral medicine]. / Prothèse amovible complète immédiate. Une réalité clinique de la médecine bucco-dentaire.

The decision to extract the last teeth represents for the patient an aesthetic, functional and moral damage. The realization of an immediate complete removable denture is indicated to remedy these difficulties. This will make it possible to ensure a rational and efficient management of this transition to total edentulous. The restorations of aesthetics and functions as well as patient comfort constitute the essential therapeutic objectives to be achieved and this thanks to the immediate denture. This work presents, through clinical cases, the indications and the management of four patients who have never worn a removable denture.

Systemic complications during voluntary cosmetic depigmentation among women in Togo: A case-control study.

OBJECTIVE: The aim of our study was to document the systemic complications of skin bleaching among women in Togo. METHODS: This was a case-control study conducted between December 2009 and December 2013. Cases comprised of women using skin-bleaching products for at least 6 months and age-matched with non-users (±3 years). RESULTS: We recruited a total of 150 women using skin-bleaching and matched them with 300 controls. Univariate analysis revealed a correlation between systolic hypertension (OR=2.56; 95% CI: 1.68-3.92), diastolic hypertension (OR=1.89; 95% CI: 1.17-3.05), hyperglycaemia (OR=1.5; 95% CI: 1.2-9, 65) and obesity (OR=1.68; 95% CI: 1.08-2.62) with the use of skin-bleaching products. Multivariate analysis revealed a correlation between skin bleaching and both systolic hypertension (OR=3.94; 95% CI: 1.59-3.75) and obesity (OR=2.88; 95% CI: 1.23-5.69). CONCLUSION: The results of our study show the existence of a correlation between voluntary cosmetic depigmentation, hypertension and obesity in Togo.
