[Prevalence and predictors of post-traumatic stress disorder in road traffic accidents]. / Prévalence et facteurs prédicteurs des troubles post-traumatiques chez les accidentés de la voie publique.

Introduction: trauma-related disorders following a road accident have both a health and an economic impact. Methods: we conducted a prospective study to determine the prevalence of these disorders, and to identify risk factors in subjects victims of road accidents and hospitalized in the Department of Orthopedic Surgery and Traumatology of the University Hospital Center of Sfax-Tunisia. Results: a total of sixty-ten subjects were included in this study. The prevalence of acute stress disorder was 37.1% and was associated with female sex, low educational level, previous medical and surgical history, passivity during the accident, severity of injuries and the presence of anxious and depressive symptoms. Post-traumatic stress disorder was observed in 40% of subjects and was associated with urban residential environment, passivity during the accident and anxious and depressive symptoms. Low scores for functional coping strategies and high scores for dysfunctional coping strategies were significantly associated with both disorders. Low educational level, urban residential environment, high levels of anxiety and depression, and denial coping strategy appear to be independent risk factors for acute stress and post-traumatic stress disorder. Conclusion: It is therefore important to determine the profile of people at greater risk of post-traumatic stress disorder, to enable early diagnosis in victims of road accidents.

First report of Sarcocystis falcatula in naturally infected Razorbill auks (Alca torda) collected in Tunisian Mediterranean Sea shores.

Sarcocystis spp. are apicomplexan cyst-forming parasites that can infect numerous vertebrates, including birds. Sarcosporidiosis infection was investigated in three muscles (breast, right and left thigh muscle) and one organ (heart) of four Razorbill auks (Alca torda) stranded between November and December 2022 on the shores of the Mediterranean Sea in Nabeul and Bizerte governorates, Northern Tunisia. Two of the four tested A. torda were PCR positive for 18S rRNA Sarcocystis spp. gene. Among the examined 16 muscles/organs, only one breast and one right thigh were Sarcocystis spp. PCR-positive (12.5% ± 8.3, 2/16). Our results showed a relatively high molecular prevalence of Sarcocystis spp. in Razorbill auks (A. torda). Sarcocystis spp. sequence described in the present study (GenBank number: OR516818) showed 99.56-100% identity to Sarcocystis falcatula. In conclusion, our results confirmed the infection of Razorbill auks (A. torda) by S. falcatula. Further research is needed on different migratory seabirds' species in order to identify other Sarcocystis species.

Therapeutic education of patients with coronary heart disease: Impact of digital platform monitoring in preventing major cardiovascular events in Tunisia: Study protocol.

BACKGROUND: Faced with the increase in the number of chronic diseases with the aging of the population, and with the observation of the insufficiency of therapeutic control, a new need has emerged, that of having a patient as a partner in care. METHODS: This study is a randomized controlled trial. Patients with coronary heart disease will be recruited from one clinical site and randomly assigned into two groups: the intervention group and the control group. All participants will be followed up for a total of one year (with three-time points for data collection). Patients who are assigned to the intervention group will receive therapeutic education at first. The digital platform will then allow healthcare providers to accompany them outside the hospital walls. The primary outcome is the incidence of major cardiovascular events within one year of discharge. Main secondary outcomes include changes in health behaviors, medication adherence, and quality of life score. The digital platform is a multi-professional telemonitoring platform that allows care teams to accompany the patient outside the hospital walls. It allows the collection and transmits information from the patient's home to the therapeutic education team. All data will be secured at a certified host. The patient application provides data on compliance, adherence to physical activity (number of steps taken per day), adequate diet (weight gain, food consumed during the meal, compliance with low-salt or salt-free diet, diabetic diet), smoking cessation, as well as medication adherence. Access to educational tools (digital media) is provided to all initial program participants. These tools will be updated annually by the rehabilitation team on the recommendations. The platform also offers the possibility of organizing an individual or group remote educational session (videoconference modules allowing group and individual sessions), a secure integrated caregiver-patient messaging system. The control group will receive the usual controls at the hospital. DISCUSSION: To offer a complete solution of care to our patients, we have thought of setting up a digital platform that aims to monitor the patient and strengthen their abilities to manage their condition daily. This pilot experience could be generalized to several services and disciplines. It could be used in several research works.

Primary breast sarcomas: A 13 case-series study treated in university hospital in central Tunisia over a 25-year period.

AIM: To retrospectively study the therapeutic modalities of primary breast sarcomas in view of the data of a local Tunisian experience. METHODS: It is a monocentric, descriptive, retrospective study including 13 cases of primary breast sarcoma treated over a period of 25 years (1995-2020) in the oncological radiotherapy department of a university hospital in Sousse, Tunisia. RESULTS: In our study, 13 cases of non-metastatic breast sarcomas that has been identified, divided into ten cases of phyllodes sarcomas and three cases of non-phyllodes sarcomas.Surgically, all our patients had a mastectomy. Among them, seven underwent a lymph node procedure: five underwent axillary lymph node dissection, and two others had primary axillary lymph node biopsy. For the adjuvant treatment, all the patients included in our study received radiotherapy and seven received chemotherapy. Local recurrence occurred on the operative scar in one patient after completion of radiation therapy. Metastatic relapse was described in five patients. The time to onset of metastases varied between two months and five years. Nevertheless, a complete remission was noted in 6 patients with a follow-up varying from four years to 20 years. Two patients were lost to follow-up. CONCLUSION: Breast sarcomas remain a very rare entity of aggressive tumors.The therapeutic approach is poorly codified. For this reason, the therapeutic decision should always be discussed in a multidisciplinary assessment.

Transcutaneous canine breast cancer detection in Tunisia: a pilot study.

BACKGROUND: Breast cancer in Tunisia is often diagnosed at a late stage with long delay in time to consultation and to diagnosis.The aim of this study is to estimate the sensitivity and specificity of the transcutaneous breast cancer detection by canine olfactionin Tunisian women and to identify the potential confounding factors. METHODS: This is a diagnostic case control study that took place from October 2021 to November 2022 in the Department of Medical Oncology at the University Hospital Farhat Hached of Sousse and in the security and training dog center located in Sousse (K9 Dog Center Security & Training). A two-year-old male Belgian Malinois was trained to detect breast cancer on skin secretion samples in compresses that had been worn overnight by women on their breast and then a double-blind testing was performed. There was no contact between women and the dog. From the mentioned responses of the dog, four parameters were calculated: sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV). RESULTS: Two hundred women were included in this trial: 100 breast cancer (BC) patients recruited from Farhat Hached University Hospital of Sousse and 100 healthy volunteers (HV).The calculated sensitivity was 84% (95% CI 78-89%) and the calculated specificity was 81% (95% CI 75-86%). The calculated predictive values were: PPV = 83,51% (95% CI 78,37-88,65%) and NPV = 81,55% (95% CI 76.17-86.93%). In the multivariate study, only four confounding factors of test's sensitivity were retained: age (OR = 1.210 [95% CI = 1.085-1.349]; p = 0.001), history of diabetes(OR = 0.017 [95% CI = 0.001-0.228]; p = 0.002), sampling at hospital (OR = 0.010 [95% CI = 0.003-0.464]; p = 0.010) and testing during chemotherapy courses (OR = 0.034 [95% CI = 0.003-0.404]; p = 0.007).For test's specificity, we retained the three following confounding factors: age (OR = 1,104 [95% CI = 1.021-1.195]; p = 0.014), history of benign mastopathy (OR = 0.243 [95% CI = 0.074-0.805]; p = 0.021)and history of arterial hypertension (OR = 0.194 [95% CI = 0.053-0.707]; p = 0.013). CONCLUSION: This is a pilot study that opens new avenues in developing a reliable cancer diagnostic tool that integrates the dog's olfactory ability to detect breast cancer using a transcutaneous sampling method. It could be a pre-test to select patients who are eligible to a screening mammogram, especially in low-income countries where there is no national mammography screening program. PACTR.

Clinical features and outcomes in patients with human immunodeficiency virus-negative, Castleman's disease: a single medical center study in Tunisia.

INTRODUCTION: Castleman's disease (CD), known as angiofollicular lymph node hyperplasia, is an uncommon condition. The two most common histological subtypes are hyaline vascular and plasma cell. We performed a retrospective analysis to define the clinic-pathological features and survival of CD, which is quite rare focusing on the particularities of our series with a review of the recent literature. METHODS: This is a retrospective study conducted in the department of internal medicine of Hedi Chaker hospital in Sfax, Tunisia over 25 years. The disease was histologically confirmed in all patients. For each file, we collected a set of data by filling in a pre-designed form. RESULTS: 18 patients were included. There were 8 men and 10 women with a mean age of 42.8 years. CD was monocentric in 5 cases (28%) and multicentric in 13 cases (72%). Clinically, peripheral adenopathy was present in 77.7% of patients and deep adenopathy in 72.2%. Systemic signs were found in 13 patients, including general condition (4.4%), fever (16.6%), serositis (27.7%), and skin involvement (33.3%). A biological inflammatory syndrome accompanied the clinical picture in 66% of patients. Abnormalities in the blood count were found in 12 cases (66%), with anemia in 11 cases, thrombocytosis in 3 cases, and hypereosinophilia in 3 cases. Cutaneous Kaposi's sarcoma was associated with Castleman's disease in 2 cases, Hodgkin's lymphoma, angioimmunoblastic T-cell lymphoma, and lymph node T-cell lymphoma were found in 1 case respectively. 3 of the patients had associated connective tissue diseases such as Sjögren's syndrome in 2 cases and rheumatoid arthritis in 1 case. HHV8 serology was positive in 1 case with a multicentric plasma cell form. Histologically, the plasma cell form represented 50% of cases, hyaline-vascular (39% of cases), and mixed (11% of cases). Therapeutically, high-dose corticosteroid therapy was initiated in 13 cases. As a second-line treatment, MOPP chemotherapy was used in 1 case due to transformation into Hodgkin's lymphoma, and biotherapy (rituximab) was used in 2 cases in the multicentric form. Surgical removal of superficial adenopathy was performed in 2 patients with monocentric CD. CONCLUSION: : Castleman's disease (CD) is a non-malignant lymphoproliferation of localized or multicentric form with a wide and heterogeneous clinical spectrum. Diagnosis can be difficult due to the lack of clinical and radiological specificity. Management depends on the clinical form involving surgical and/or medical management.

Occupational Risk Factors for Laryngeal Cancer in Tunisia: A Case Control Study.

BACKGROUND: Tobacco use and alcohol consumption are the primary risk factors for laryngeal cancer (LC). In most populations, occupational exposures are likely to play a minor role in laryngeal carcinogenesis. We aimed to investigate the association between occupational exposure and laryngeal cancer. METHODS: It is a case-control study that included 140 cases diagnosed between January 2013 and December 2016 and 140 controls matched by sex, age, alcohol consumption, and tobacco consumption. RESULTS: Significantly increased risks were found amongst workers of the building sector (OR=4.621; 95% CI [1.826-11.693]) and the mechanical industry sector (OR=5.074; 95% CI [1.425-18.072]). Significant association of laryngeal cancer with various carcinogens was observed such as asbestos (p=0.009; OR=3.68; 95% CI [1.29-10.46]), paint vapors (p=0.005; OR=3.35; 95% CI [1.37-8.16]), solvents (p=0.001; OR=3.29: 95% CI [1.61-6.68]) and cement dust (p=0.003; OR=3.19: 95% CI [1.43-7.12]). After binary logistic regression, cement dust was independently correlated with LC (p=0.042; OR=3.93; 95% CI [1.04-14.78]. The administration sector was associated with decreased risk (p=0.001; OR=0.07; 95% CI [0.03-0.15]) as well as the health sector (p=0.001; OR=0.098; 95% CI [0.02-0.43]). CONCLUSIONS: Our results supported the role of occupational factors in developing LC. Further studies enabling an in-depth analysis of occupational exposures are necessary to provide a clearer definition of the etiological associations between single agents and circumstances of exposure and the genesis of LC.

Contrast media-induced nephropathy in Tunisia: prospective case-control study with cardio-nephrological monitoring.

Introduction: vascular opacification using iodinated contrast media (ICM) is often the primary diagnostic and therapeutic approach. However, the risk of post-injection nephrotoxicity of ICM is significantly higher in patients with underlying nephropathy. This study aimed to determine the incidence of Contrast Media Induced Nephropathy (CMIN) and identify predictive factors for its occurrence in patients from a cardiology department. Methods: our prospective study involved 158 patients who underwent coronary angiography or angioplasty at the cardiology department between December 2017 and May 2018. Two types of ICM were used in our study: Iopromide and Iohexol. All patients received either physiological serum (9‰) or bicarbonate serum (14‰) intravenously for hydration. We defined impaired renal function as an increase in creatinine ranging from 10 to 26 µmol/L, while CMIN was defined as an increase in serum creatinine exceeding 26.5 µmol/L. We investigated the factors associated with CMIN using logistic regression analysis. Results: the mean age of our patients was 60 ± 11 years (range: 29-82), with a predominance of men 63.9% (n=101). The most common cardiovascular risk factors were tobacco (36.1%, n = 57), diabetes (48.1%, n =76), hypertension (55%, n = 87). Pre-procedural creatinine averaged 81.1 ± 47.3 µmol / L with extremes ranging from 39 to 600 µmol / L. The median Mehran risk score was 3.2 (range: 0- 15). The interventional cardiology act consisted of coronary angiography in 86.2% (n=136) of cases, coronary angioplasty in 2.5% (n=4) of cases. We used iohexol and iopromide in 57.6% (n=91) and 42.4% (n=67) of cases, respectively. The overall incidence of CMIN was 9.5% (n=9). The multivariable regression analysis identified 4 risk factors independently linked to the occurrence of CMIN which were Pre-existing renal failure (OR: 6.05, 95%CI [1.23-29.62], p = 0.026), anemia (OR: 0.043, CI [1.03-8.96], p = 0.043), the toxic dose of PC (OR: 4.7, CI [1.28-17.7], p=0.02), and at a Mehran score = 11 (OR: 3.7, CI [0.88-15.6], p=0.036). Conclusion: the most effective approach for CMIN is prevention, which focuses on addressing modifiable risk factors to minimize the risk especially in patients with pre-existing renal failure.

Pathologically confirmed women's breast cancer: A descriptive study of Tunisian and Algerian series.

BACKGROUND: Breast cancer (BC) is the most frequent malignancy among women in Tunisia and Algeria. Clinical and pathological characteristics of this cancer among these populations are not widely reported. The aim of the study was to report clinical and pathological characteristics of women's BC in a Tunisian and Algerian series. METHODS: Pathologically confirmed 1089 BCs were gathered in the pathology departments of three Northern Tunisian hospitals: Tunis military, Charles Nicolle and Jendouba and in the pathology department of Alger Douera hospital between January 2015 and December 2020. Clinical and pathological findings of the two series: age, tumor size, histological type, grading according to Scarff-Bloom Richardson grading system, lymph node status at the time of diagnosis in axillary lymphadenectomy specimens and the immunohistochemical expression of estrogen and progesterone receptors (ER/PR), HER2 and Ki-67, were collected from the pathological reports. RESULTS: The median age at diagnosis was 50 and 48 years in Tunisian and Algerian series, respectively (p = 0.016). The diagnosis of BC was made on surgical specimens (lumpectomy or mastectomy) in 373/491 (76%) cases of the Tunisian series and in 225/598 (37.6%) cases of the Algerian one. Median tumor size was 2.8 cm and 2.5 cm in Algerian and Tunisian series, respectively (p = 0.252). Invasive BCs not otherwise specified was observed in 440/481 (91.5%) BCs in Tunisian series and in 519/586 (88.6%) BCs in Algerian series. Axillary lymph node positive tumors were observed in 64.6% and 58.8% of Tunisian and Algerian women, respectively (p = 0.926). BCs were ER positive in 311/385 (80.8%) and 486/571 (85.1%) cases and HER2 positive in 86/283 (30.4%) and 60/385 (15.6%) cases of Tunisian and Algerian series, respectively. CONCLUSIONS: In Tunisia and Algeria, BC has poor prognostic factors with large tumor sizes and high rates of lymph nodes involvement at diagnosis.

Burden of cancer attributable to insufficient physical activity in Tunisia.

Background: Insufficient physical activity is a risk factor for several types of cancer. Therefore, estimating the burden of cancer attributable to insufficient physical activity is essential to evaluate the effect of health promotion and prevention interventions. Aims: We estimated the number of incident cancer cases, deaths and disability-adjusted life years (DALYs) attributable to insufficient physical activity in the Tunisian population aged 35 years and older in 2019. Methods: We estimated the age-specific population attributable fractions by sex and cancer site to estimate the proportion of cases, deaths and DALYs that could be avoided with optimal levels of physical activity. We used data on cancer incidence, mortality and DALYs from the Global Burden of Disease study estimates for Tunisia in 2019, and data on physical activity prevalence from a Tunisian population-based survey in 2016. We used site-specific relative risk estimates from meta-analyses and comprehensive reports. Results: The prevalence of insufficient physical activity was 95.6%. In 2019, 16 890 incident cancer cases, 9368 cancer-related deaths and 230 900 cancer-related DALYs were estimated to have occurred in Tunisia. We estimated that 7.9% of incident cancer cases, 9.8% of cancer-related deaths and 9.9% of cancer-related DALYs were attributable to insufficient physical activity. At cancer sites known to be associated with inadequate physical activity, 14.6% of cancer cases, 15.7% of deaths and 15.6% of DALYs were attributable to insufficient physical activity. Conclusion: Insufficient physical activity contributed to almost 10% of the cancer burden in Tunisia in 2019. Reaching optimal physical activity levels would considerably reduce the burden of associated cancers in the long-term.

Associated factors with adherence to preventive behaviors related to COVID-19 among medical students in the university of Monastir, Tunisia.

INTRODUCTION: Medical students should act as a model for the community in terms of compliance with preventive practices toward COVID-19. The aim of this study was to assess adherence to preventive behaviors related to COVID-19 among medical students and to identify its associated factors. POPULATION AND METHODS: We conducted a cross-sectional survey in October 2020 in the faculty of medicine of Monastir. We included a representative sample of medical students during registration days for the 2020-2021 academic year. The data were collected through a self-administered anonymous questionnaire. Eleven items related to preventive practices against COVID-19 were assessed (respiratory hygiene practices (Six Item), hand hygiene practices (Three Items) and social distancing (two items)). Items were evaluated using a Likert scale of five points (from 0: (Never) to 4: (Always)). The score obtained from the sum of these items allowed to classify students into two categories: "Good compliance" if the score was ≥ 80% and "Poor compliance" if the score was less than 80%. Scores were compared according to the study population characteristics. Multivariate analysis was used to identify associated factors with good practices. The threshold of statistical significance was set at p < 0.05. RESULTS: We included 678 medical students. The average age was 21.76 (SD = 1.89 years) with a sex ratio of 0.40. The protection measures most respected by the participants were related to the respiratory hygiene: correct coverage of the nose and mouth with the mask (80%), wearing masks regardless of the presence of symptoms (73.3%) and coverage of the mouth during coughing or sneezing (76.6%). Adherence to hand hygiene measures ranged from 51.4% to 66.3%. The least respected measures were related to social distancing: distancing of at least one meter from others (31.2%) and avoiding crowded places (42.5%). An overall score ≥ 80% was obtained among 61.5% of students. Referring to multivariate analysis, variables that positively affected the overall score of preventive measures related to COVID-19 were the female sex and living alone, with Beta coefficients of 3.82 and 1.37 respectively. The perceived level of stress, E-cigarette and Chicha consumption negatively affected the score with Beta coefficients of (-0.13), (-5.11) and (-2.33) respectively. CONCLUSION: The level of adherence to good practice among medical students was overall moderate. Awareness programs would be needed in this population, especially for men and those who smoke and vape.

Biclonal Gammopathies in South Tunisia: Clinical and Biological Characteristics.

OBJECTIVE: Biclonal gammopathies (BGs) are rare situations characterized by the production of 2 monoclonal proteins. There are no available data on BGs in North Africa. We aimed to estimate the prevalence of BGs in our population and describe their clinical and laboratory features. METHODS: We conducted a 31-year retrospective study including patients with persistent double monoclonal bands based on the results of immunofixation/immunoelectrophoresis. RESULTS: A total of 35 patients with available clinical data (sex ratio, M/F = 1.53; mean age, 70 ±â€…10.87 years [range, 45-90 years]) were included. The main associated conditions were multiple myeloma (MM) (40%), BG of undetermined significance (BGUS) (34%), and lymphoproliferative diseases (23%). Only one-third of the patients had 2 monoclonal spikes on serum protein electrophoresis. The most common paraprotein combinations were immunoglobulin (Ig)G-IgG (25%) and IgG-IgA (23%) with different light chains in one-half of the cases. The mean follow-up was 25.6 months (median, 12 months). No BGUS evolved into a malignant disease. CONCLUSION: BGs are rare in clinical laboratory routine but must be accurately identified by the pathologist. Our cohort is characterized by a high prevalence of BGUS compared with MM.

Incidence and risk factors of SARS-CoV-2 infection among workers in a public health laboratory in Tunisia.

The aim of this study was to measure the extent of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among workers at the Institut Pasteur de Tunis (IPT), a public health laboratory involved in the management of the COVID-19 pandemic in Tunisia, and to identify risk factors for infection in this occupational setting. A cross-sectional survey was conducted on IPT workers not vaccinated against coronavirus disease 2019 (COVID-19). Participants completed a questionnaire that included a history of reverse transcription-polymerase chain reaction (RT-PCR)-confirmed SARS-CoV-2 infection. Immunoglobulin G antibodies against the receptor-binding domain of the spike antigen (anti-S-RBD IgG) and the nucleocapsid protein (anti-N IgG) of the SARS-CoV-2 virus were detected by enzyme-linked immunoassay (ELISA). A multivariate analysis was used to identify factors significantly associated with SARS-CoV-2 infection. A total of 428 workers were enrolled in the study. The prevalence of anti-S-RBD and/or anti-N IgG antibodies was 32.9% [28.7-37.4]. The cumulative incidence of SARS-CoV-2 infection (positive serology and/or previous positive RT-PCR test) was 40.0% [35.5-44.9], while the proportion with asymptomatic infection was 32.9%. One-third of the participants with RT-PCR-confirmed infection tested seronegative more than 90 days postinfection. Participants aged over 40 and laborers were more susceptible to infection (adjusted OR [AOR] = 1.65 [1.08-2.51] and AOR = 2.67 [1.45-4.89], respectively), while tobacco smokers had a lower risk of infection (AOR = 0.54 [0.29-0.97]). The SARS-CoV-2 infection rate among IPT workers was not significantly different from that detected concurrently in the general population. Hence, the professional activities conducted in this public health laboratory did not generate additional risk to that incurred outside the institute in day-to-day activities.

Distribution of high-risk human papillomavirus in women with ASC-US or LSIL in Tunisian women: Place of HPV testing for women triage in Tunisia.

The present study aimed to evaluate the distribution of oncogenic HPVs in Tunisian women diagnosed with ASC-US or LSIL in order to highlight the importance of HPV testing in the management of women with minor cytological lesions. The study involved 213 cervical samples from women aged from 18 to 82 years and diagnosed with ASC-US or LSIL. HPV detection and genotyping was performed by nested PCR followed by reverse Line Blotting. HPV DNA was identified in 161 cases (76.3%). Oncogenic HPV genotypes were detected in 53.1% of cases. The most frequent high-risk genotypes in this study were HPV16 (28.8%) followed by: HPV51 (9.6%), HPV18, HPV31 HPV56 (7.1%) and HPV45 (5.1%). Thus, 24 % of studied women were not infected by HPV and about 47% of infections are without oncogenic HPV. These results highlight the value of HPV testing in the decision algorithm of management of minor abnormalities lesions.

Health related quality-of-life in systemic sarcoidosis in Tunisia.

INTRODUCTION: Sarcoidosis is a systemic granulomatosis that can be associated with large-scale physical and mental disability, affecting the health related quality-of-life (HRQoL) of patients. AIM: To evaluate the HRQoL of tunisian patients with sarcoidosis and to identify the factors that influence it. METHODS: We conducted an analytical, cross-sectional study collecting 31 patients with sarcoidosis according to the ATS/ERS/WASOG criteria. The evaluation of the HRQoL was assessed by two questionnaires in tunisian dialect. The generic score was the Medical Outcome Study 36-Short Form Health Survey (SF-36).The specific score used was the Sarcoidosis Health Questionnaire (SHQ). RESULTS: The HRQoL of our 31 patients was more affected in the three domains of the SHQ compared to the SF-36, which is in favor of the better sensitivity of the SHQ to detect the influence of the extent of sarcoidosis on the HRQoL. Factors associated with more impaired HRQoLwere: age at disease onset, age at interview, comorbidities, altered spirometry results, ocular involvement, chronic cholestasis, splenic nodules, arthralgia, organ count ≥3, lymphopenia and cholestasis at the time of the interview. Taking an immunosuppressant agent, particularly Methotrexate, was associated with HRQoL improvement. The number of relapses was the most correlated factor with an altered HRQoL, and this in several domains. CONCLUSION: For an effective management of patients with sarcoidosis, a bio-psycho-social approach is now necessary in order to assess the real and global impact of the disease and to improve the HRQoL of patients. Disease-specific scores seem more reliable in achieving these goals.

Cross-sectional study of co-occurring addiction problems among high school students in Tunisia.

Background: Addictive behaviours are a major public health problem, especially among adolescents, who are susceptible to experiencing multiple co-occurring addictions. Aim: To assess the prevalence of addiction problems and co-occurrences of addictive behaviours (substance abuse, problematic video gaming and social media addiction) and disorders among high school students in Sousse, Tunisia. Methodology: A cross-sectional study was conducted in 2018 in public high schools, in the urban area of Sousse, Tunisia. A structured self-administered questionnaire was used to obtain relevant information from the students. Statistical analysis was performed using SPSS version 10 and confidence intervals of 95% were calculated. Chi-square test was used to compare qualitative variables and multinomial regression was conducted to determine independent factors related to the number of addictive behaviour co-occurrences. Results: Of the 1399 high school students, 60.5% were girls and mean age was 17 ± 2.28 years. Analysis of single addiction problems revealed 20.9% prevalence for all tobacco products, 10.1% for alcohol, 7.0% for all drugs, 36.1% for Facebook, and 35.3% for video games. Analysis of co-occurring addiction problems showed that 46.0% of the study population had 1 addiction problem, 12.2% had 2 addiction problems, 4.5% had 3, and 2.7% had the maximum number of 4 addiction problems. Multinomial regression showed an increase in co-occurrence of addiction problems among boys (aOR = 217.004; P < 0.001), participants who had repeated a school grade (aOR = 0.232; P < 0.001), those who had moderate or severe depression (aOR = 0.232; P < 0.001), and those who were anxious (aOR = 0.335; P = 0.003) and had alexithymia (aOR = 0.361; P = 0.005). Conclusion: The rate of co-occurrent addictions among adolescents in Sousse, Tunisia, is alarming. Problematic use of Facebook, gaming and tobacco use were the most frequent addictive behaviours. There is an urgent need for effective and multisectoral programmes to prevent addictions among children in Tunisia and other countries in the Middle East and North Africa Region.

Childhood obesity in Tunisia: Prevalence and risk factors.

INTRODUCTION: Obesity in children is currently a major public health problem in Tunisia. AIM: To determine the prevalence of obesity among pre-schoolchildren in the city of Bardo and to identify risk factors. METHODS: We carried a cross-sectional study of 220 children between 4 and 6 years of age, recruited from kindergartens in the city of Bardo. Children with endocrinal, tumoral or genetic diseases causing secondary obesity, children on corticosteroids and children with two illiterate parents were not included. The weight status of the children was defined according to the curves of the international obesity task force. A parent is considered obese if his BMI>30 Kg/m². RESULTS: The average age was 4.65±0.77 years. A female predominance was noted (55.9% girls and 44.1% boys). The average BMI of the children was 16.93±2.46 kg/m². The prevalence of overweight among all children was 10.9% and that of obesity was 11.4%. The frequency of overweight (including obesity) was 22.3%. In multivariate analysis, factors independently related to childhood obesity were child age, child medical history and hospitalization, parental obesity, parental dyslipidemia, snack type and snacking. CONCLUSIONS: Overweight is common in pre-school children. It should be detected at an early age, especially if risk factors are present.

Clinical and therapeutic characteristics of childhood uveitis in a tertiary center in Tunisia.

INTRODUCTION: Childhood uveitis is a rare condition with various associated diagnostic and therapeutic challenges. AIM: We proposed to describe the distribution, clinical findings, treatment, complications, and visual outcomes of uveitis in children at a tertiary referral center in Sfax, Tunisia. METHODS: A retrospective study of 33 children (54 eyes) with uveitis collected over the period from January 2009 to December 2018 was carried out at the Ophthalmology Department of Habib Bourguiba University Hospital, Sfax, Tunisia. The data from the clinical examination, the etiological assessment, and the used treatments were collected. Standard diagnostic criteria were used for all uveitic syndromes or entities. RESULTS: The mean age of the patients was 11.42 years with a male-to-female ratio of 0.74. Uveitis was bilateral in 63% of the patients. The most common anatomical form was intermediate uveitis (39%). Idiopathic cases accounted for 52%. The major complications were posterior synechiae, optic disc edema, cataract, and cystoid macular edema. Anti-infective treatment was prescribed in 24% of the patients. Oral corticosteroid therapy was used in 67% of the patients. 18% of the patients received immunosuppressive therapy and 6% received a biological agent. The mean final visual acuity was 4.6/10. CONCLUSION: Childhood uveitis is a serious pathology with frequent and vision-threatening complications. The etiologies are variable and the assessment can remain negative. A rigorous diagnostic approach, an oriented etiological assessment in collaboration with the pediatrician, and an appropriate therapy are necessary for management.

Performance of the ADRESS-HCC score in the assessment of the risk of hepatocellular carcinoma in viral cirrhosis in Tunisia.

INTRODUCTION: The ADRESS-HCC score allows predicting the risk of occurrence of Hepatocellular carcinoma in cirrhosis at one year of follow-up. AIM: Measuring the performance of ADRESS-HCC in predicting the risk of degeneration on post-viral cirrhosis, in a gastroenterology department in Tunisia. METHODS: Retrospective study, including patients followed for compensated viral cirrhosis in the gastroenterology department of the Mohamed Taher Maamouri hospital. The ADRESS-HCC score was calculated at diagnosis of cirrhosis. We divided patients into two groups depending on whether they developed Hepatocellular carcinoma or not. We evaluated the performance of the ADRESS-HCC score in predicting the risk of Hepatocellular carcinoma according to a threshold value. RESULTS: We enrolled 60 patients; the mean age was 62 years. Twenty-five patients developed hepatocellular carcinoma during follow-up. The mean value of ADRESS-HCC score was 5.08. To predict the occurrence of hepatocellular carcinoma at 1 year of follow-up, the area under the curve of the ADRESS-HCC score was 0.74 (p=0.01). For a threshold value of 5.63 its sensitivity was 91 % with a negative predictive value of 95.83%. CONCLUSION: The ADRESS-HCC score had an average performance in predicting degeneration in post-viral cirrhosis.

Epidemiology of metabolic syndrome in Tunisia. HSHS 5 study.

OBJECTIVE: To measure the prevalence of metabolic syndrome and its components in the HSHS cohort (Hammam Sousse, Tunisia), in 2009, and to identify its determining factors. METHODS: This was a descriptive epidemiological study of the "community based" type having focused on a random sample of people aged 20 and over. The metabolic syndrome was defined according to the criteria of the "International Diabetes Federation" (IDF 2005) and those of the "National Cholesterol Education Program-Adult Treatment Panel III" (NCEP-ATP III, 2001). RESULTS: The study involved 1441 people including 960 women (66.6%). The age- and sex-adjusted prevalences of increased waist circumference, blood pressure, blood sugar and triglycerides, and decreased HDL-cholesterol were respectively 63.2%, 95%CI[62.5-63.8]; 47.7%, 95%CI[47.4-48.6]; 25.7%, 95%CI[25.1-26.2]; 11.9%, 95%CI[11.4-12.3] and 65,6%, 95%CI[65.0-66.2], according to IDF thresholds and 37.4%, 95%CI[36.3-37.6]; 45.7%, 95%CI[45.4-46.6]; 13.8%, 95%CI[13.4-14.2]; 8.4%, 95%CI[8.0-8.7] and 61.9%, 95%CI[61.2-62.5], according to those of the NCEP-ATP III. The prevalence of metabolic syndrome adjusted for age and sex was 36.5% 95%CI[33.0%-38.9%] according to the IDF definition and 23.0% 95%CI[20.4%-25.6%] according to that of NCEP-ATP III. The multivariate study by logistic regression made it possible to retain three significant independent determining factors of the metabolic syndrome: age ≥40 years, low level of physical activity and family history of diabetes mellitus with respectively adjusted ORs of 3.77 95%CI[2.70-5.27], 1.39 95%CI[1.01-1.89], 1.62 95%CI[1.21-2.15], according to IDF and 5.87 95%CI[3.88 -8.88], 1.47 95%CI[1.07-2.01] and 1.45 95%CI[1.07-1.96], according to NCEP-ATP III . CONCLUSION: With this high prevalence rate of the metabolic syndrome, the establishment of an action plan would be essential. This plan should be based on the combination of the promotion of physical activity and screening for the components of the metabolic syndrome, particularly in subjects aged 40 or over, with a family history of diabetes mellitus.
