Furthermore, we investigated the pharmacological potential of Trimetazidine (TMZ) in ameliorating lung fibrosis.Results: Our results revealed that the BLM-treated group exhibited a significant upregulation in the expression of epigenetic regulators, lncRNA CBR3-AS1 and FIZZ1, compared to the control group (P< 0.0001), along with the downregulation of miRNA-29 expression. Furthermore, Correlation analysis showed a significant positive association between lnc CBR3-AS1 and FIZZ1 (R=0.7723, p< 0.05) and a significant negative association between miRNA-29 and FIZZ1 (R=− 0.7535, p< 0.05), suggesting lnc CBR3-AS1 as an epigenetic regulator of FIZZ1 in lung fibrosis. BLM treatment significantly increased the expression of Notch, Jagged1, Smad3, TGFB1, and hydroxyproline. Interestingly, the administration of TMZ demonstrated the ability to attenuate the deterioration effects caused by BLM treatment, as indicated by biochemical and histological analyses. Our investigations revealed that the therapeutic potential of TMZ as an antifibrotic drug could be ascribed to its ability to directly target the epigenetic regulators lncRNA CBR3-AS1/ miRNA-29/ FIZZ1, which in turn resulted in the mitigation of lung fibrosis. Histological and immunohistochemical analyses further validated the potential antifibrotic effects of TMZ by mitigating the structural damage associated with fibrosis.Discussion: Taken together, our study showed for the first time the interplay between epigenetic lncRNAs CBR3-AS1 and miRNA-29 in lung fibrosis and demonstrated that FIZZ1 could be a downregulatory gene for lncRNA CBR3-AS1 and miRNA-29. Our key findings demonstrate that TMZ significantly reduces the expression of fibrotic, oxidative stress, immunomodulatory, and inflammatory markers, along with epigenetic regulators associated with lung fibrosis. This validates its potential as an effective antifibrotic agent by targeting the CBR3-AS1/miRNA-29/FIZZ1 axis.

Context: The changing trends have revealed that cardiovascular disease (CVD) has evolved as prime cause of mortality globally, and predicting this prior is of utmost interest in patient management. Objective: To assess the ten-year risk of fatal or non-fatal cardiovascular event using World Health Organization/ International Society of Hypertension (WHO/ISH) risk prediction chart among adults. Material and methods: A cross sectional study was conducted among 226 general medicine Outpatient Department (OPD) attendees of a tertiary care hospital. Their risk of encountering a major cardiovascular event such as myocardial infarction or stroke ten year later was assessed using the WHO/ISH risk prediction charts. Appropriate tests of significance were employed. Results: Among 226 study subjects, 174 (76.9%) at low risk, 36 (15.9%) at moderate risk and 16 (7.0%) were at high risk of developing major cardiovascular event in the next ten years. Risk factors such age above 50 years, male gender, presence of hypertension or diabetes and smoking were found to be significantly associated with increased risk of the predicted major cardiovascular event. Conclusions: WHO/ISH chart is a useful tool in identifying individuals at high-risk of cardiovascular disease (CVD) and could help in planning appropriate strategies to mitigate the estimated CVD burden in future.

A total of 60 pregnant women who had previously experienced multiple miscarriages were randomly assigned to intervention and control groups (n=30 each). The tools used for data collection were demographic and obstetric data questionnaires and the 21-item Depression, Anxiety, and Stress Scale (DASS-21). Happiness counseling sessions were conducted for the intervention group. Data for qualitative variables were analyzed with the chi-squared test, and the Student’s t test for paired samples was used to compare mean DASS-21 scores of the intervention and control groups. The Pearson correlation coefficient was used to analyze the association between variables.Results: The happiness counseling sessions reduced depression, anxiety, and stress in women with recurrent miscarriage, resulting in lower mean DASS-21 scores for the intervention group compared to the control group.Conclusion: The happiness counseling program had a positive effect on reducing depression, anxiety, and stress in women with recurrent miscarriage. We recommend that this program be used as an effective, low-cost, and noninvasive intervention to improve the mental health and overall wellbeing of women with recurrent miscarriage.Keywords: happiness counseling program, depression, anxiety, stress, recurrent miscarriage

Apparently matched for age and gender, healthy participants (n= 90) were enrolled as a control group. Serum samples were tested for micro-RNAs (−122, −34a and −99a) by quantitative-PCR.Results: By histopathology, 124 of the NAFLD group were of SS and 86 patients were of NASH. Compared with the control subjects, both mi-RNA-122 and −34a levels were increased in NAFLD (p< 001) and at a cut-off = 1.261, mi-RNA-122 had 92% sensitivity, 85% specificity to differentiate NAFLD from healthy controls, while mi-RNA-99a were significantly decreased in NAFLD patients with an observed decrease in disease severity, and at a cut-off = 0.46, miRNA-99a had 94% sensitivity and 96% specificity to discriminate SS from NASH.Conclusion: The integration of a circulating mi-RNA panel to diagnose NAFLD cases and to discriminate between SS and NASH. Large-scale study is still needed to verify the other mi-RNA profiles and their role in NAFLD pathogenesis and targeting therapy.Keywords: NASH, NAFLD, micro-RNA, simple steatosis

Abstract Background In the current treatment landscape for non-small cell lung cancers, epidermal growth factor receptor-tyrosine kinase inhibitors have emerged as a well-established treatment option for patients with advanced or metastatic disease. This is particularly true for those with commonly occurring epidermal growth factor receptor mutations. However, the therapeutic efficacy of these agents for so-called rare epidermal growth factor receptor mutations, and in particular those characterized by a high degree of complexity, such as double mutations, remains a subject of clinical uncertainty. Case presentation In this context, we present the case of a 64-year-old man of Moroccan descent, a lifelong non-smoker, diagnosed with metastatic non-small cell lung cancer characterized by a complex epidermal growth factor receptor mutation encompassing L858R and S768I. The patient subsequently underwent afatinib-based treatment, showing notable clinical results. These included a remarkable overall survival of 51 months, with a median progression-free survival of more than 39 months. Conclusions This case report is a compelling testimony to the evolving therapeutic landscape of non-small cell lung cancers, providing valuable insight into the potential therapeutic efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors in the realm of rare and complex epidermal growth factor receptor mutations.

Fibrosing mediastinitis, also known as sclerosing mediastinitis, is an uncommon condition marked by abnormal proliferation of fibrous tissue in the mediastinum. This condition may accrue either as an idiopathic condition or as a complication of an underlying disease process. Its pathogenesis remains unknown. However, most reported cases are incriminating abnormal immune-mediated hypersensitivity responses to Histoplasma infection. Other rare causes include tuberculosis, blastomycosis, and an idiopathic form that may be associated with other miscellaneous conditions. CT and MR imaging play a vital role in the diagnosis and management of this disease. We present a rare case of fibrosing mediastinitis as a late complication of tuberculosis in a 34-year-old man with a prior history of mediastinal tuberculosis, mimicking initially a neoplastic mediastinal process. We will describe this clinical case in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Background: Metabolic syndrome (MetS) is a global health concern, especially for low and middle-income countries with limited resources and information. The study's objective was to assess the prevalence of MetS in Freetown, Sierra Leone, using the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III), International Diabetes Federation (IDF) and Harmonize ATP III. Additionally, we aimed to establish the concordance between these three different criteria used. Methods: This community-based health screening survey was conducted from October 2019 to October 2022. A multistage stratified random design was used to select adults aged 20 years and above. Mean, interquartile range (IQR), and logistic regression were used for statistical analysis. The kappa coefficient statistics resolved the agreement between these defined criteria. Results: The prevalence for NCEP ATP III, Harmonize ATP III and IDF criteria was 11.8 % (95 % CI: 9.0–15.15), 14.3 % (95 % CI: 11.3–18.0), and 8.5 % (95 % CI: 6.2–11.2), respectively for the 2394 selected adults. The kappa coefficient (κ) agreement between the MetS is: Harmonized ATP III and IDF criteria = [(208 (60.8 %); (κ = 0.62)]; Harmonized ATP III and NCEP ATP III = [(201 (58.7 %); (κ = 0.71)]; while IDF and NCEP ATP III was [(132 (38.6 %); (κ = 0.52)]. In the multivariable regression analysis, waist circumference correlated with all three MetS criteria: ATP III [AOR = 0.85; C.I 95 %: (0.40–1.78), p = 0.032], Harmonized ATP III [AOR = 1.14; C.I 95 %: (0.62–2.11), p = 0.024], IDF [AOR = 1.06; C.I 95 % (0.52–2.16), p = 0.018] Conclusion: We reported a high prevalence of MetS in Freetown, Sierra Leone and identified waist circumference as a major risk factor for MetS. This underscores the crucial role of health education and effective management of MetS in Sierra Leone.

Objective To investigate the prevalence of cardiometabolic risk factors (CMRFs), target organ damage (TOD) and its associated factors among adults in Freetown, Sierra Leone.Design This community-based cross-sectional study used a stratified multistage random sampling method to recruit adult participants.Setting The health screening study was conducted between October 2019 and October 2021 in Western Area Urban, Sierra Leone.Participants A total of 2394 adult Sierra Leoneans aged 20 years or older were enrolled.Outcome measure Anthropometric data, fasting lipid profiles, fasting plasma glucose, TOD, clinical profiles and demographic characteristics of participants were described. The cardiometabolic risks were further related to TOD.Results The prevalence of known CMRFs was 35.3% for hypertension, 8.3% for diabetes mellitus, 21.1% for dyslipidaemia, 10.0% for obesity, 13.4% for smoking and 37.9% for alcohol. Additionally, 16.1% had left ventricular hypertrophy (LVH) by ECG, 14.2% had LVH by two-dimensional echo and 11.4% had chronic kidney disease (CKD). The odds of developing ECG-LVH were higher with diabetes (OR=1.255, 95% CI (0.822 to 1.916) and dyslipidaemia (OR=1.449, 95% CI (0.834 to 2.518). Associated factors for higher odds of Left Ventricular Mass Index by echo were dyslipidaemia (OR=1.844, 95% CI (1.006 to 3.380)) and diabetes mellitus (OR=1.176, 95% CI (0.759 to 1.823)). The odds of having CKD were associated with diabetes mellitus (OR=1.212, 95% CI (0.741 to 1.983)) and hypertension (OR=1.163, 95% CI (0.887 to 1.525)). A low optimal cut-off point for ECG-LVH (male 24.5 mm vs female 27.5 mm) was required to maximise sensitivity and specificity by a receiver operating characteristics curve since the odds for LVH by ECG were low.Conclusions This study provides novel data-driven information on the burden of CMRF and its association with preclinical TOD in a resource-limited setting. It illustrates the need for interventions in improving cardiometabolic health screening and management in Sierra Leonean.

Background: Head and neck cancer (HNC) encompasses malignant tumors in areas like the oral cavity, pharynx, and larynx. This analysis identifies strengths and deficiencies in HNC research, aiming to improve published papers' quality, quantity, and diversity. It also encourages more participation from oncologists, particularly in Egypt, to bridge the gap with Western healthcare standards. Methods: A systematic search was conducted in databases including PubMed, Scopus, Web of Science, and Embase. The goal was to gather research articles on HNC in Egypt published from January 1, 2000, to December 31, 2022. Results: From 2150 articles, 1329 were screened by title and abstract, leading to 193 for full-text review. Finally, 174 articles were included in the final analysis. 2020 saw the highest number of publications. The majority were primary research articles, with randomized controlled trials being prevalent. Most studies were clinical, focusing on radiotherapy, and involved adult patients, emphasizing service delivery. Publications were predominantly in non-Egyptian journals, with the Egyptian Journal of Radiology and Nuclear Medicine being the most frequent. Research was mainly conducted by Egyptian authors and at Cairo University. Conclusion: The growing prevalence of HNC in Egypt underscores the need for more comprehensive research on its various aspects, including etiology, risk factors, and prevention. There's a call for increased research outputs at different Egyptian universities, multicenter studies, and international collaborations. This approach can improve the understanding and management of HNC, contributing to global discussions and advancing treatment and prevention strategies in Egypt.

Background: We herein report the case of a patient with advanced lung adenocarcinoma who presented a heterogeneous distribution of EGFR mutation. Case report: A 74-year-old Moroccan male former smoker was diagnosed with advanced lung adenocarcinoma, harboring S768I exon 20 substitution mutation confirmed by Real Time PCR and Pyrosequencing, but not detected by direct sequencing despite 70% of tumor cells. The present report describes a case of minor histologic intratumoral heterogeneity with heterogeneous distribution of EGFR mutation. Conclusion: Both sensitivity and specificity of molecular methods can provide evidence of intratumoral heterogeneity, which may explain the mismatch between the validation of oncology biomarkers and predicting therapeutic response to targeted therapy.

Pulmonary re-expansion edema (PRE) was first described by Carlston in 1958. To the knowledge, only one case has been described following pleuropulmonary decortication. The authors present the case of a 19-year-old patient who underwent pleuropulmonary decortication and who presented an PRE intraoperatively. Early diagnosis and the rapidity of treatment allowed a favourable evolution. Therefore, the prognosis of intraoperative PRE depends on the rapidity and efficiency of medical management.

Thymolipoma is a rare benign neoplasm of the thymus containing both mature adipose tissue and thymic tissue. We report a case of a 34‐year‐οld man, presenting a mass of the anterior mediastinum, the radiology investigation and operatory piece diagnosed a thymolipoma.This study highlights the clinical diagnostic and therapeutic features as well as the evolutionary characteristics of this entity.

Objective Our prospective study aims to define the correlation of EGFR (epidermal growth factor receptor) mutations with major histological subtypes of lung adenocarcinoma from resected and non-resected specimens, according to the WHO 2015 classification, in Moroccan North East Population. Methods Epidermal growth factor receptor mutations of 150 primary lung adenocarcinoma were performed using Real-Time PCR or SANGER sequencing. SPSS 21 was used to assess the relationship between histological subtypes of lung adenocarcinoma and EGFR mutation status. Results 25 mutations were detected in the series of 150 lung adenocarcinomas, most of which were found in cases with papillary, acinar, patterns than without these patterns and more frequently occurred in the cases without solid pattern than with this pattern. A significant correlation was observed between EGFR mutation and acinar (P = 0,024), papillary pattern (P = 0,003) and, negative association with a solid pattern (P < 0,001). In females, EGFR mutations were significantly correlated with the acinar pattern (P = 0,02), whereas in males with the papillary pattern (P = 0,01). Association between the histologic component and exon 19 deletions and exon 21 mutations were also evaluated and, we found a significant correlation between the papillary major pattern with exon 19 mutations (P = 0,004) and, ex21 with the acinar component (P = 0,03). Conclusion An analysis of resected and non-resected lung ADC specimens in 150 Moroccan Northeast patients, revealed that acinar and papillary patterns may predict the presence of a mutation in the EGFR gene. While the solid major pattern may indicate a low mutation rate of the EGFR gene.

Primary tumor of the trachea is rare. Although most tumors in adults are malignant, various benign tumors might occur. However, pleomorphic adenoma of the trachea is extremely rare. So far, few cases have been reported in medical literature. We report a case of a 38-year-old man with 6 months history of dyspnea and wheezing; the asthma was the initial diagnosis formulated by his family doctor. However, the symptoms were not improved by asthma treatment. The patient was admitted to the emergency department for respiratory distress, and underwent nasal continuous positive airway pressure. Immediately, after an urgent chest computed tomography (CT) was done and revealed an obstructive tumor of the distal trachea which was homogeneous with a smooth and regular surface suggesting its benignity. The patient was operated urgently, the histological examination of the surgical specimen revealed pleomorphic adenoma. We present this case to inform colleagues that pleomorphic adenoma must be considered in the differential diagnosis of tracheal tumors, especially if we have an appearance on CT suggesting the benignity. Surgery is the treatment of choice of this tumor with the lowest recurrence probability.

Despite having safe and efficacious vaccines against COVID-19, vaccine hesitancy is widespread. Although a trusted source of information, vaccine hesitancy has been reported among healthcare professionals, yet few studies have explored this phenomenon in sub-Saharan Africa. We conducted a cross-sectional survey of healthcare professionals in Sierra Leone from January to March 2022. Measures included sociodemographic/health-related information and COVID-19-related concerns. From the responses, we constructed a hesitancy (VAX) score, with higher scores implying negative attitudes or unwillingness to vaccinate. Multivariate linear regression was used to access factors associated with vaccine hesitancy. Overall, 592 participants submitted responses (67.2% female, mean age 29 years, 5.6% physicians/pharmacists, 44.3% medical students, 29.2% nurses, 20.9% nursing students). The mean VAX score was 43.27 ± 8.77, with 60.1% of respondents classified as vaccine hesitant (>50th percentile) and 13.8% as highly hesitant (>75th percentile). Worries about unforeseen future effects (76.3%), a preference for natural immunity (59.5%), and profiteering/mistrust of health authorities (53.1%) were the most common concerns. Being a medical student (β = 0.105, p = 0.011) and previously refusing a recommended vaccine (β = 0.177, p < 0.001) were predictors of COVID-19 vaccine hesitancy. Our findings call for addressing vaccine hesitancy among healthcare professionals as an essential component of strategies aimed at increasing COVID-19 vaccine uptake in this setting.

In this paper, a hybrid position/force controller for electrohydraulic servo-actuators is designed in the presence of residual dynamics. The purpose is to apply a cycle of movement that is mostly used in industrial fatigue test applications, which consists in imposing a specified force on a flexible load after a movement to some position. This cycle can be repeated several times with different magnitudes and frequencies of force and position trajectories. Some damages could occur at switching times, especially in the presence of some residual dynamics. To avoid any damages at switching times, a force trajectory generator is designed. Then, our contribution defines a method to automatically generate the switching signal in order to commute between two controllers with any abrupt change of state. To show the effectiveness of the proposed approach, several simulation tests are carried out on the electrohydraulic system.

Abstract Background The occurrence of lung metastasis from benign uterine leiomyomas is rarely reported especially in post menopausal women. The pathogenesis of these metastatic benign tumors still remains a subject of various speculations. Case presentation A 57-year-old woman presented with a chronic cough and dyspnea. She had undergone 8 years previously, hysterectomy for benign leiomyomas. A chest computed tomography scan showed a 4 cm solitary nodular parenchymal tumor that increased in size after 12 months. The histological analysis of the biopsy from this nodule showed a benign tumor with regular spindle cells disposed in intersected fascicles. At immunohistochemical analysis, the tumor cells were positive for smooth muscle markers and oestrogen-progesterone receptors with a low mitotic index assessed by Ki-67. These features were consistent with a benign metastasizing uterine leiomyoma. At the multidisciplinary meeting, prescription of an aromatase inhibitor has been decided for the patient. Conclusions Benign metastasizing uterine leiomyomas of the lung are very rare tumors. Although extremely rare in post menopausal women, their diagnosis should be considered in symptomatic patients with a history of hysterectomy for leiomyomas.

Although parathyroid ectopy in the mediastinum has been the subject of several publications, its location in the posterior mediastinum is very rarely reported. We report a case of a 69-year-old patient who presented with clinical symptoms of malignant hypercalcemia due to a retrotracheal mediastinal parathyroid adenoma. The surgical excision leads to a quick normalisation of the phosphocalcic balance with improvement of the clinical symptoms. Ectopic hypersecreting parathyroid adenoma with life-threatening hypercalcemia should prompt radiological assessment and appropriate surgical management to prevent further clinical complications.

The aim of the study was to evaluate the efficacy of clonidine in association with fentanyl as an additive to bupivacaine 0.25% given via single shot caudal epidural in pediatric patients for postoperative pain relief. In the present prospective randomized double blind study, 40 children of ASA-I-II aged 1-5 years scheduled for infraumblical surgical procedures were randomly allocated to two groups to receive either bupivacaine 0.25% (1 ml/kg) with fentanyl 1 g/kg and clonidine 1g/kg (group I) or bupivacaine 0.25% (1 ml/kg) with fentanyl 1 g/kg (group II). Caudal block was performed after the induction of general anesthesia. Postoperatively patients were observed for analgesia, sedation, hemodynamic parameters, and side effects or complications.Both the groups were similar with respect to patient and various block characteristics. Heart rate and blood pressure were not different in 2 groups. Significantly prolonged duration of post-operative analgesia was observed in group I (P=0.05). Side effects such as respiratory depression, vomiting and bradycardia were similar in both groups. The adjunction of clonidine to fentanyl as additives to bupivacaine in single shot caudal epidural in children may provide better and longer analgesia after infraumblical surgical procedures.

INTRODUCTION: bien que la plupart des principes de réhabilitation précoce post césarienne paraissent applicable dans nos structures de soins, il semble que la mise en èuvre reste e. METHODES: il s'agit d'une enquête structurée par courrier électronique auprès des médecins anesthésistes de la région de Sfax décrivant leurs pratiques habituelles dans les maternités étatiques et privées de la région de Sfax. Nous avons utilisé un questionnaire dans le cadre de prise en charge de la césarienne programmée.

This paper aims to propose and develop an adaptive moving sliding mode controller (AMSMC) that can be applied for nonlinear single-input single-output (SISO) systems with external disturbances. The main contribution of this framework consists to overcome the chattering phenomenon problem. The discontinuous term of the classic sliding mode control is replaced by an adaptive term. Moreover, a moving sliding surface is proposed to have better tracking and to guarantee robustness to the external disturbances. The parameters of the sliding surface and the adaptive law are deduced based on Lyapunov stability analysis. An experimental application of electropneumatic system is treated to validate the theoretical results.

INTRODUCTION: la thoracoscopie est l'exploration endoscopique de la cavité pleurale, des organes avoisinants (diaphragme, péricarde, médiastin) et du poumon. Le but de ce travail se veut d'abord didactique ; décrivant la thoracoscopie, ses techniques ainsi que sa place dans la prise en charge de la pathologie thoracique (indications et perspectives thérapeutiques) et informatif en rapportant l'expérience de notre équipe. METHODES: il s'agit d'une étude rétrospective intéressant 104 thoracoscopies à visée diagnostique et/ou thérapeutique réalisées au service de chirurgie thoracique du Centre Hospitalier Universitaire Hassan II de Fès, sur une période de 04 ans (Août 2008-décembre 2012). Nous avons exclu de notre étude les cas ayant bénéficié d'une médiastinoscopie ainsi que les cas ayant bénéficié d'une thoracoscopie dans le cadre des traumatismes fermés du thorax ou des plaies thoraciques. RESULTATS: l' âge moyen des patients est de 47 ans, avec des extrêmes allant de 18 à 80 ans, et une légère prédominance masculine à 54%.La thoracoscopie est d'ordre pleural chez 86 patients, pulmonaire chez 10 patients et médiastinale chez 8 patients. La thoracoscopie avait une indication à visée diagnostique chez 87 cas et thérapeutique chez 52 patients (talcage dans 45 cas, décortication pleuropulmonaire dans 2 cas, résection de kystepleuro-péricardique dans 2 cas, cure de pneumothorax dans 2 cas et une fenêtre péricardique). L'évolution post opératoire etait marquée par une amélioration clinico-radiologique chez 40 malades, 11 ont présenté une amélioration clinique seule, 6 ont présenté une persistance ou une récidive de l'épanchement. CONCLUSION: la thoracoscopie représente un réel gain en matière de diagnostic de certaines pathologies intra-thoraciques. Son intérêt thérapeutique limité doit être éventuellement étendu grâce à la chirurgie thoracique vidéo assistée, qui est une technique récente fiable avec une limitation de la durée d'hospitalisation et de la morbidité.

L'hyperemesis gravidarum s'accompagne habituellement d'une perte de poids, d'une acétonurie et de troubles hydro-électrolytiques comme il peut également s'accompagner d'anomalies du bilan hépatique. Nous rapportons un cas de vomissements gravidiques à 10 semaines d'aménorrhée non traité et vu tardivement avec des troubles ioniques sévères associés à des répercussions cliniques dans un contexte de cytolyse, de cholestase et d'insuffisance rénale aigue. Ce cas a bien répondu au traitement médical.

Les sarcomes ténosynoviaux ou synovialosarcomes sont des tumeurs malignes des tissus mous, l'atteinte primitive de la paroi thoracique est rare. Nous rapportons l'observation d'un patient suivi pour des douleurs thoraciques avec à l'examen une masse pariétale, le bilan radiologique a montré un développement également endothoracique de la tumeur. L'analyse anatomopathologique de la biopsie de la masse a conclu à un synovialosarcome, le patient a eu une résection de la tumeur associé à une radio chimiothérapie, le suivi a été marqué par la récidive au bout d'un an. A travers cette observation, nous insistons sur la rareté de la localisation, les caractères histologiques, les différentes approches thérapeutiques et le pronostic de ces tumeurs qui reste péjoratif.

Nous rapportons un cas de tuberculose costale chez une patiente de 44ans ayant des antécédents de miliaire tuberculeuse. L’atteinte costale était pseudotumorale ayant conduit à une biopsie exérèse chirurgicale de la masse costale dont l’étude histologique est revenue en faveur d’une tuberculose. Cette observation ainsi que celles de la littérature, confirment les difficultés diagnostiques de cette forme rare de tuberculose.

Les fistules bilio thoraciques post traumatiques sont extrêmement rares, leur traitement peut être conservateur mettant en œuvre des techniques de radiologie et d’endoscopie interventionnelle ou chirurgical si échec du premier. Nous rapportons une observation de fistule bilio pleurale post traumatique où l’indication du traitement chirurgical de première intention a été indiscutable vu le sepsis et l’instabilité hémodynamique.
