RESUMO
INTRODUCTION: Langerhans cell histiocytosis (LCH) is a rare systemic disease characterized by the abnormal overproduction of histiocytes that tend to infiltrate single or multiple organ systems leading to significant tissue damage. Although LCH can involve various organs including bone, skin, and lymph nodes, multisystem involvement of LCH is rare in adults. CASE PRESENTATION: We report the case of a 31-year-old man with LCH involving his lungs and bone. The initial radio-clinical presentation was rather in favor of pulmonary tuberculosis. Through this observation we draw attention to this rare pathology and we discuss the diagnostic elements and the therapeutic management of this pathology. CONCLUSION: Although it is occasionally difficult to discriminate LCH from other disorders, systemic evaluation might be helpful for differential diagnosis. As LCH isn't infiltrating malignant cells, strong chemotherapy regimen is not recommended in order to avoid severe toxic and side effects.

Post-COVID19 patients suffer from persistent respiratory, cardiovascular, neurological, and musculoskeletal health complaints such as dyspnea, chest pain/discomfort, and fatigue. In Tunisia, the potential benefits of a cardiorespiratory rehabilitation program (CRRP) after COVID19 remain unclear. The main aim of this study was to evaluate the impact of a CRRP on submaximal exercise capacity, evaluated through the 6-min walk test (6MWT) data in post-COVID19 Tunisian patients. This was a cross-sectional study including 14 moderate to severe COVID19 patients aged from 50 to 70 years. CRRP was performed after the end of patients' hospitalization in COVID19 units for extensive or severe extents of COVID19. Dyspnea (modified medical research council), spirometry data, handgrip strength values, 6MWT data, and 6-min walk work (i.e., 6-min walk distance x weight) were evaluated 1-week pre-CRRP, and 1-week post-CRRP. CRRP included 12 sessions [3 sessions (70 min each)/week for 4 weeks]. Exercise-training included aerobic cycle endurance, strength training, and educational sessions. Comparing pre- and post- CRRP results showed significant improvements in the means±standard deviations of dyspnea by 1.79 ± 0.80 points (p < 0.001), forced expiratory volume in one second by 110 ± 180 ml (p = 0.04), 6-min walk distance by 35 ± 42 m (p = 0.01), 6-min walk work by 2,448 ± 3,925 mkg (p = 0.048), resting heart-rate by 7 ± 9 bpm (p = 0.02) and resting diastolic blood pressure by 6 ± 10 mmHg (p = 0.045). In Tunisia, CRRP seems to improve the submaximal exercise capacity of post-COVID19 patients, mainly the 6-min walk distance and work.
RESUMO
OBJECTIF: Etudier la valeur pronostique de l'évaluation de la qualité de vie (QDV) pour la survie chez les patients Tunisiens atteints du CDP. Méthodes: Une étude prospective de cohorte a été réalisée entre Janvier 2018 et Juin 2019. Le Performance status (PS), QoL questionnairecore30 (QLQ-C30), QoL questionnaire-Lung Cancer 13 (QLQ-LC13) et European QoL-5 dimensions-3level version questionnaire (EQ-5D-3L) ont été utilisés pour l'évaluation de la QDV. Les patients ont été divisés en 2 groupes selon le score global QLQ-C30, un Déficit Cliniquement Significatif (DCS) a été considéré si le score était ≤50. Les modèles de régression de Cox et Stepwise ont été réalisée pour évaluer la signification pronostique de la QDV. La survie globale (SG) a été calculée à l'aide de la méthode de Kaplan-Meier. Le test du log-rank a été utilisé pour comparer les courbes de survie. Le seuil de valeur de p pour la signification statistique était de 0,05. Résultats: Cent patients ont été inclus. La médiane de SG des patients avec DCS en qualité de vie était significativement inférieure à celle des patients sans déficit : respectivement 365 jours versus 467 jours, (test du log-rank, p = 0,036). De même pour la médiane de survie sans progression : 122 jours versus 326 jours pour ceux qui n'ont pas signalé de différence significative en QDV (test du log-rank, p = 0,05). L'analyse de régression multivariée stepwise a montré que le score global de QDV (QLQ-C30) était un facteur prédictif significatif de SG (coefficient estimate (CE)= 0.336, p=0.005), ainsi que le stade IV (CE=-0.193, p=0.033) et la progression tumorale (CE =-0.238, p=0.047). CONCLUSION: La QDV était un facteur prédictif de survie dans notre cohorte de patients atteints de CDP. Cela devrait recommander une intervention active en soins palliatifs précoces pour les patients présentant un déficit significatif en QDV.

Erythema nodosum (EN) is an inflammatory condition of the subcutaneous fat and has been reported in patients with haematological malignancies (lymphomas) or solid tumours. Lung cancer is the most common cause of paraneoplastic syndrome. We report a case of EN occurring as a paraneoplastic disease. A 48-year-old Tunisian woman, a non-smoker with no relevant medical history, presented with painful, erythematous, firm nodules on her legs with ankle swelling. The patient did not report any other symptoms. There were no abnormalities on examination except for moderate fever. An extensive infectious and immunological investigation was negative. Antistreptolysin antibodies were undetectable. Chest radiography showed a focal opacity in the right lung and a CT scan revealed a mass in the lower right pulmonary lobe with hilar and mediastinal lymphadenopathies, a nodule in the right adrenal gland, condensation in the iliac bone and multiple bilateral nodular cerebral expansive processes. Bronchial biopsies revealed a primitive and moderately differentiated adenocarcinoma. No argument for tuberculosis or sarcoidosis was found. LEARNING POINTS: Erythema nodosum (EN) can be idiopathic.EN has rarely been associated with lung cancer and so the association may be coincidental in our patient.The lung cancer was easily identified by chest x-ray in this case and in cases described in the literature.
RESUMO
BACKGROUND: No previous study has investigated the adherence rate of North-African pulmonologists to the 2017-GOLD PTGs. AIMS: To investigate the adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs and to identify the barriers to their adherence. METHODS: This was a cohort study involving clinically stable COPD patients who presented to a pulmonology outpatient consultation. The patients were classified as having been appropriately and inappropriately (over- or undertreatment) treated for the GOLD group. Logistic regression was performed to determine the adherence barriers to the 2017-GOLD PTGs. RESULTS: A total of 296 patients were included (88.1% males, mean age: 68 ± 10 years; GOLD A (7.1%), B (36.1%), C (4.1%), and D (52.7%)). The pulmonologists' adherence rate to the 2017-GOLD PTGs was 29.7%. There was a significant statistical difference between the adherence rates among the four GOLD groups (A: 19.0%, B: 20.6%, C: 8.3%, and D: 39.1%; p = 0.001). Differences were statistically significant between the GOLD group D and groups B (p = 0.001). Differences were statistically significant between the GOLD group D and groups B (p = 0.001). Differences were statistically significant between the GOLD group D and groups B (. CONCLUSION: The adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs is low. It seems that the patients' age, socioeconomic level, national health insurance coverage, and GOLD groups influenced their adherence.

Gingival metastasis of lung cancer is uncommon. We report the case of an 82-year-old male smoker admitted to the pulmonology department with right pleural effusion. A chest computed tomography (CT) scan showed an invasive right hilar tumour, adherent to the superior vena cava, pulmonary artery, main right bronchus, mediastinal pleura and pericardium with lymphangitic carcinomatosis of the right lung. Pleural biopsy revealed pleural metastasis of pulmonary adenocarcinoma, its primary lung origin being confirmed by immunohistochemistry. One month later, the patient developed an ulcerated polypoid gingival mass. Biopsy of this lesion showed a poorly differentiated carcinoma compatible with metastasis from the lung adenocarcinoma. The patient underwent irradiation of the gingival mass at a dose of 30 Gray, but his condition worsened rapidly and he was not fit for chemotherapy. He received palliative treatment and died 2 months after diagnosis of his metastatic lung cancer. LEARNING POINTS: Lung cancers mostly metastasize to the bones, liver, lymph nodes, brain, lung and adrenal glands, with adenocarcinoma being the most common histological type.Distant metastasis to the oral region is very uncommon but can be the first manifestation of a primary tumour.Oral metastasis can be mistaken for a benign lesion, so a biopsy should be taken for further analysis.
RESUMO
Catamenial pneumothorax (CP) is a rare entity of spontaneous, recurring pneumothorax in women. We aim to discuss the etiology, clinical course, and surgical treatment of a 42-year-old woman with CP. This patient had a right-sided spontaneous pneumothoraces occurred one week after menses. She had under-gone video-assisted thoracoscopic surgery (VATS) because of a persistent air leak under chest tube. VATS revealed multiple diaphragmatic fenestrations with an upper right nodule. Defects were removed and a large part of the diaphragm was resected. Pleural abrasion was then performed over the diaphragm. Diaphragmatic endometriosis was confirmed by microscopic examination. Medical treatment with GnRH agonists was prescribed, and after recovery, the patient has been symptoms free for 20 months.
