Sleep Habits and Disturbances Among Tunisian Adults: A Cross-Sectional Online Survey.

Background: Sleep quality and disturbances have gained heightened scholarly attention due to their well-established association with both mental and physical health. This study aims to assess sleep-wake habits and disturbances in Tunisian adults. Methodology: This cross-sectional study employed an online questionnaire to assess 3074 adults ≥ 18 years. Primary outcomes, including sleep quality, daytime vigilance, mood, and subjective well-being, were measured using validated questionnaires [the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), the Epworth Sleepiness Scale (ESS), the Patient Health Questionnaire (PHQ)-9, and the World Health Organisation-Five Well-Being Index (WHO-5)]. Results: Less than two-thirds (n= 1941; 63.1%) of participants were females and the mean age was 36.25±13.56. The prevalence of poor sleep quality was 53.8% when defined as a PSQI > 5. The prevalence of insomnia, short sleep duration, long sleep duration, EDS, severe depression, and poor well-being were 14.5%, 34.7%, 12.3%, 32.4%, 7.4%, and 40.2%, respectively. Some factors were associated with an increased likelihood of poor sleep quality, including female gender, chronic hypnotics use, internet use close to bedtime, daily time spent on the internet >3 hours, smoking, university- level education, nocturnal work, severe depression, impaired well-being status, insomnia, and EDS. Conclusion: The high prevalence of sleep-wake disturbances among Tunisian adults emphasizes the need for an appropriate screening strategy for high-risk groups. Individuals with unhealthy habits and routines were significantly more likely to experience these kinds of disturbances. Consequently, there is a pressing need for educational programs on sleep to foster healthier sleep patterns.

Diagnosis and management of pituitary apoplexy: a Tunisian data.

BACKGROUND: Pituitary apoplexy (PA) is defined as the hemorrhage or the infraction of a pituitary adenoma. Aiming to determine the epidemiological, clinical, paraclinical characteristics as well as management and outcomes of PA in our population, we conducted this cross-sectional study. METHODS: This cross-sectional study was conducted at the Department of Endocrinology of Hedi chaker university hospital, Sfax. Data was collected from medical charts of patients with pituitary apoplexy admitted in our department between 2000 and 2017. RESULTS: We included 44 patients with PA. Their mean age was 50 ± 12.6 years. Among them, 31.8% had a known pituitary adenoma, and it was in all cases a macroadenoma, predominantly a prolactin secreting tumor (42.8%). A triggering factor of PA was encountered in 31.8% of cases and it was mainly: head trauma, dopamine antagonists, and hypertension. The clinical presentation of PA encompassed headaches (84.1%), visual disturbances (75%), and neurological signs (40.9%). Gonadotropin deficiency was the most frequent form of hypopituitarism noted (59.1%), followed by corticotropin deficiency (52.3%), thyrotropin deficiency (47.7%), and somatotropin deficiency (2.3%). Hormonal assessment at PA onset, concluded that 23 had a secreting adenoma: 18 prolactinomas, 3 ACTH-secreting adenomas, and 2 GH-secreting adenomas. In the 21 remaining cases, the tumor was non-functioning (47.7%). Pituitary MRI was performed in 42 cases (95.5%), revealing infraction and or hemorrhage in the pituitary gland in 33 cases; a heterogenous signal or a fluid level within the adenoma, in nine cases. Urgent administration of intra venous hydrocortisone was required in 19 cases. Mannitol administration was mandatory in a patient who had severe intracranial hypertension. Surgical management of the PA was imperative in 24 patients (54.5%): 15 suffered from severe visual impairment, 4 had an intracranial hypertension, 2 cases demonstrated an impaired consciousness, 2 patients experienced a tumor enlargement and one case had a severe Cushing's disease. Operative complications found were rhinorrhea attributable to cerebral spinal fluid leakage, insipidus diabetes associated with rhinorrhea, isolated insipidus diabetes, and hydrocephalus in one case each. Long-term follow-up concluded that headaches persisted in five cases, owing to the tenacity of a macroprolactinoma regardless of cabergoline treatment in one case, the recurrence of an adenoma in two cases and its persistence despite the medical and the surgical treatment in two patients. Concerning the visual acuity defects, only two patients had persistent diminished visual acuity at long-term follow-up. Among 25 patients, 13 were diagnosed with definitive thyrotropin deficiency. Similarly, 14 patients had persistent corticotropin deficiency (CD). Additionally, CD was de novo diagnosed in two patients. Otherwise, gonadotropin deficiency prevailed in all cases. Persistent prolactin deficiency was seen in two patients. Disappearance of the pituitary tumor was encountered in 11 out of 24 cases at long-term follow-up. Overall, surgery was associated with better outcome than conservative management. Pituitary apoplexy is a challenging condition due to its variable course, its diagnosis difficulty and management, as gaps remain to determine the best approach to treat this condition. CONCLUSIONS: To conclude, pituitary apoplexy is a challenging condition due to its variable course, its diagnosis difficulty and management, as gaps remain to determine the best approach to treat this condition. Further studies are thus needed.

Prognostic value of Quality of life (QoL) assessment among Tunisian lung cancer patients.

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.

Factors Associated With Insulin Pump Discontinuation in Adults With Diabetes: A Time-to-Invent Analysis and Prediction Model.

OBJECTIVE: Insulin pump discontinuation has mostly been studied in children and adolescents living with diabetes. We aimed to assess the rate of insulin pump continuation in a population of adult patients with diabetes, at 18 months after initiation; determine the factors associated with pump discontinuation; and develop a simple prediction model. METHODS: This single-center, retrospective study included all adult patients with type 1 diabetes or type 2 diabetes who started insulin pump treatment between January 2015 and June 2018. The exclusion criteria were pregnancy, short-term pregnancy plans, and insulin pump discontinuation within the previous 6 months. The probability of insulin pump continuation after 18 months was estimated using the Kaplan-Meier method. Factors associated with insulin pump discontinuation were studied using a Cox regression model, and an exponential model was built for prediction purposes. RESULTS: The study included 315 patients. The mean age was 41 years, the mean duration of diabetes was 16 years, 50% were men, 74% had type 1 diabetes, and the mean hemoglobin A1c level was 9.1% (76 mmol/mol). After 18 months, the rate of insulin pump continuation was 0.80 (95% Confidence Interval (CI), 0.76-0.85). By multivariate analysis, the occurrence of severe hypoglycemia in the previous year was associated with insulin pump discontinuation (hazard ratio, 2.42; 95% CI, 1.30-4.51), while other factors did not reach statistical significance. CONCLUSION: Insulin pump discontinuation occurred in 20% of patients at 18 months after initiation and was mainly associated with a recent history of severe hypoglycemia. The type of diabetes and glycemic control at baseline were not associated with treatment discontinuation.

Erythema Nodosum Revealing Metastatic Lung Cancer.

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.

Adherence of North-African Pulmonologists to the 2017-Global Initiative for Chronic Obstructive Lung Disease (GOLD) Pharmacological Treatment Guidelines (PTGs) of Stable Chronic Obstructive Pulmonary Disease (COPD).

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.

Seasonality of Pulmonary Tuberculosis in Sousse (Tunisia).

INTRODUCTION: Seasonal variation of Pulmonary tuberculosis (TB) has attracted the attention in several regions of the world. AIM: To explore the relationship between variations of mean meteorological parameters (temperature, atmospheric pressure, relative humidity and duration of sunshine) and the occurrence of cases of pulmonary TB. METHODS: This is a retrospective descriptive study of two-time series (meteorological data, case of pulmonary TB) from 1th January 2010 to 31th December 2014.Meteorological data were collected throughout the 5-year period. RESULTS: We collected 180 cases confirmed by direct examination. The relationship between seasonality and the occurrence of TB cases was addressed in two ways considering either the date of the bacteriological diagnosis or the date date of onset of symptoms of TB as the date of the census of cases. Taking into account the date of bacteriological diagnosis, it appeared that spring (33.7%) and summer (25.9%) had the most days with positive diagnosis (p = 0.012). However, considering the date of onset of symptoms of TB , it appeared that winter (34.2%) and spring (28%) had the most days with positive diagnosis with a significant difference. The comparison of the mean of meteorological parameters between days with and without bacteriological diagnosis showed that only the mean duration of sunshine was significatively associated with more cases(p=0.002). This same comparison between the days with and without TB according to the date of onset of symptoms of TB showed significant difference only for mean temperatures which were lower  during the days when patients présented symptoms of TB (p=0.013). CONCLUSION: Our results have highlighted the possible implication of meteorological parameters in the occurrence of pulmonary TB cases.

Quality of life of Tunisian patients with lung cancer: descriptive study.

INTRODUCTION: No previous study has set as primary goal the evaluation of the quality of life (QOL) of Tunisian patients with lung cancer (LC). AIM: To evaluate the QOL of Tunisian patients with LC. METHODS: This was a cross-sectional descriptive study. QOL of 100 patients with LC (90 men) was evaluated via the QLQ-C30 and QLQ-LC13 questionnaires. QLQ-C30 data were compared with international reference values. RESULTS: 40, 38, 7 and 15% of patients had, adenocarcinoma, squamous cell carcinoma, large cell and small cell LC, respectively. 72, 20 and 8% of patients had received chemotherapy, combination of chemotherapy and surgery or radiotherapy, respectively. The means±SDs of the QLQ-C30 were 3717 (QOL), 5121 (physical activity), 3921 (life role activity), 9113 (cognitive activity), 6622 (emotional activity), 2720 (social activity), 5517 (fatigue), 5120 (pain), 820 (nausea/vomiting), 4221 (dyspnea), 6623 (insomnia), 5125 (anorexia), 4932 (constipation), 1021 (diarrhea) and 7173 (financial problems). The scores means±SDs of dyspnea, cough, hemoptysis, sore mouth and tongue, dysphagia, peripheral neuropathy, alopecia, chest pain, pain in arm or shoulder, and other pain sites were, 5116, 4523, 1319, 1819, 1017, 3430, 1522, 4720, 4534, and 1419, respectively. Comparison of QLQ-C30 data with international reference values showed an alteration of all scores except of those of emotional activity, nausea/vomiting, dyspnea and diarrhea. CONCLUSION: Tunisian patients with LC had poor QOL.

A rare cause of cough: Agenesis of the right pulmonary artery.

Unilateral pulmonary artery agenesis is a rare malformation. It can lead to several complications.The diagnosis is usually set at adolescence, however it can remain asymptomatic and late diagnosis is possible. Diagnosis is based on thoracic angioscanner. Treatment is essentially symptomatic. A 20-year-old male patient presented to our clinic with a history of cough and dyspnea with an abnormal chest X-ray. Physical examination was normal. Chest X-ray, CT-Scan and Pulmonary ventilation-perfusion scintigraphy led to the diagnosis of right pulmonary artery agenesis. Unilateral agenesis of the pulmonary artery with pulmonary hypoplasia is a rare malformation whose prognosis can be fatal. Once the diagnosis has been established medical follow up is mandatory.

Does Ramadan Fasting Affect Spirometric Data of Healthy Adolescents?

PURPOSE: Several studies raised the effects of Ramadan fasting on healthy adults spirometric data, but none was performed in children. The aim of this study was to compare the spirometric data of a group of faster adolescents (n = 26) with an age-matched non-faster one (n = 10). METHODS: This comparative quasi-experimental study, including 36 healthy males aged 12 to 15 years, was conducted during the summer 2015 (Ramadan: June 18 to July 16). Three sessions (Before-Ramadan [Before-R], Mid-Ramadan [Mid-R], After-Ramadan [After-R]) were selected for spirometry measurements. Spirometry was performed around 5.5 to 3.5 h before sunset and the spirometric data were expressed as percentages of local spirometric norms. RESULTS: The two groups of fasters and non-fasters had similar ages and weights (13.35 ± 0.79 vs 12.96 ± 0.45 years, 46.8 ± 9.2 vs 41.7 ± 12.6 kg, respectively). There was no effect of Ramadan fasting on forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow, and maximal mid-expiratory flow. For example, during the Before-R, Mid-R, and After-R sessions, there was no significant difference between the fasters and non-fasters mean FVC (101 ± 11 vs 99 ± 14, 101 ± 12 vs 102 ± 14, 103 ± 11 vs 104 ± 13, respectively) or FEV1 (101 ± 13 vs 96 ± 16, 98 ± 11 vs 97 ± 16, 101 ± 10 vs 98 ± 16, respectively). CONCLUSIONS: Ramadan fasting had no interaction effect with the spirometric data of Tunisian healthy male adolescents.

Influence of Weather Conditions on the Onset of Spontaneous Pneumothorax in the Region of Sousse (Tunisia): Analysis of Time Series.

INTRODUCTION: Weather conditions were implicated in the onset of spontaneous pneumothorax (SP). AIM: Investigate the influence of weather conditions on the onset of SP. METHODS: A total of 200 patients with SP in Sousse (Tunisia) were enrolled in the study between January 2010 and December 2014. An analysis of two time series (meteorological data and pneumothorax cases) was performed. Data on weather conditions were collected daily throughout the 5-year period. RESULTS: A comparison of the mean temperature between days with and without SP showed significantly higher temperatures during the days with SP. A decrease of 1% in the relative humidity one day lag (D-1) was associated with an increase in the risk of SP by 1.6% (p=0,02). The occurrence of clusters was associated significantly with higher temperature averages on the same days. This same observation was made regarding the mean duration of sunshine two days before the cluster onset (p = 0.05). The occurrence of storms two days before clusters was also significantly associated with a risk multiplied by 1.96. CONCLUSION: There was a correlation between clusters of spontaneous pneumothorax and weather conditions in the region of Sousse-Tunisia.

Lung Adenocarcinoma with Gingival Metastasis.

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.

Catamenial pneumothorax revealing diaphragmatic endometriosis: a case report and revue of literature.

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.

Adherence to treatment with continuous positive airway pressure in the obstructive sleep apnea syndrome.

INTRODUCTION: Continuous positive airway pressure (CPAP) is the most effective treatment for obstructive sleep apnea (OSA). Adequate compliance with the use of CPAP is cardinal to achieve cardiovascular, metabolic and neuropsychological benefits of treatment. AIM: Assess the factors affecting compliance to the CPAP treatment and analyze the long term acceptance. METHODS: Retrospective study on 130 patients treated by CPAP for OSA in the department of pulmonology between 2005 and 2014.  Long term acceptance was analysis using the method of survival analysis. RESULTS: These patients are characterized by a mean age of 55.4± 10.2 years; main comorbidities were found hypertension (47%), diabetes (25.5%) and COPD (11%). Median baseline apnea-hypopnea index was (AHI), 56 ± 19,5/h. One hundred thirty patients were enrolled with a mean follow up of 75 ± 34 months, 42 patients stopped their treatment, 21% of them in the first 6 months.  In compliant patients, the median value of daily CPAP use was 5, 5 ± 2 hours. Kaplan Meier analysis showed that 96% of patients were still using CPAP at 12 months, 69,4% at 5 years and 64,1% at 10 years. Chronic Obstructive Pulmonary Disease was identified as a predictor factor of long term CPAP use. Non observing patients had a higher probability to stop the use of CPAP compared to adherent patients Conclusion: the treatment of OSA with CPAP is generally well accepted in the long term. Treatment dropouts are more common among non-adherent patients justify regular monitoring in the first months of treatment.
