The aim is to evaluate laparoscopic cholecystectomy safety based on American Society of Anesthesiologists score for acute cholecystitis in patients with comorbidities. This is retrospective study of patients who underwent laparoscopic cholecystectomy for acute cholecystitis between 2003 and 2021. According to their respective ASA-score, patients were divided into group 1: ASA1-2 and group 2: ASA3-4.

Article Synopsis
  • The study examines how to best measure the general factor of psychopathology using various statistical models on data from youth ratings in 24 societies.
  • Four models were tested: principal axis, hierarchical factor, bifactor, and a simple Total Problem score, analyzing data from over 25,000 youth ages 11-18.
  • Findings show that all models yielded similar results, suggesting that the simplest approach (the Total Problem score) is recommended for evaluating youth psychopathology in both clinical and research settings.

  • There is a lack of national studies on HPV genotype distribution in Tunisia, making it difficult to evaluate the burden of cervical cancer that could be prevented by vaccines.
  • A national survey conducted between December 2012 and December 2014 analyzed HPV prevalence in a sample of 1,517 Tunisian women, finding an overall infection rate of 7.8%.
  • Key risk factors identified included residing in the Grand Tunis region, marital status, smoking, occupation, and having multiple sexual partners, highlighting the need for increased HPV vaccination efforts and cervical cancer prevention programs in Tunisia.

Background: The mass vaccination campaign against SARS-CoV-2 was started in Tunisia on 13 March 2021 by using progressively seven different vaccines approved for emergency use. Herein, we aimed to evaluate the humoral and cellular immunity in subjects aged 40 years and over who received one of the following two-dose regimen vaccines against SARS-CoV-2, namely mRNA-1273 or Spikevax (Moderna), BNT162B2 or Comirnaty (Pfizer-BioNTech), Gam-COVID-Vac or Sputnik V (Gamaleya Research Institute), ChAdOx1-S or Vaxzevria (AstraZeneca), BIBP (Sinopharm), and Coronavac (Sinovac).

Material And Methods: For each type of vaccine, a sample of subjects aged 40 and over was randomly selected from the national platform for monitoring COVID-19 vaccination and contacted to participate to this study.

Background: In the 1980s, Tunisia was considered a country of high endemicity for hepatitis A virus (HAV). Since 2000, an epidemiologic shift has led to an increased incidence of symptomatic and severe forms of HAV infection.

Objectives: In 2015, we conducted a cross-sectional nationwide household-based hepatitis A virus (HAV) seroprevalence study in the total population regardless of age, sex, or geographic origin using a stratified sampling design to make an overview of the HAV epidemiologic situation in Tunisia before vaccine implementation.

Carpal tunnel syndrome is one of the the most common reasons for consultation in hand surgery with an annual incidence of 300 per 100 000 inhabitants and, in France, of 80 000 surgical interventions. In most cases, carpal tunnel syndrome is idiopathic occurring without a recognizable cause. However, beyond these forms, the merging of several mechanisms can explain the cause-and-effect relationship of this pathology .

As societies become increasingly diverse, mental health professionals need instruments for assessing emotional, behavioral, and social problems in terms of constructs that are supported within and across societies. Building on decades of research findings, multisample alignment confirmatory factor analyses tested an empirically based 8-syndrome model on parent ratings across 30 societies and youth self-ratings across 19 societies. The Child Behavior Checklist for Ages 6-18 and Youth Self-Report for Ages 11-18 were used to measure syndromes descriptively designated as , and .

Transmission of zoonotic cutaneous leishmaniasis (ZCL) depends on the presence, density and distribution of Leishmania major rodent reservoir and the development of these rodents is known to have a significant dependence on environmental and climate factors. ZCL in Tunisia is one of the most common forms of leishmaniasis. The aim of this paper was to build a regression model of ZCL cases to identify the relationship between ZCL occurrence and possible risk factors, and to develop a predicting model for ZCL's control and prevention purposes.

Aim: The study was conducted in order to identify high risk areas for hydatidosis in Tunisia witch would be eligible for a Hydatidosis control program initiation.

Methods: The most recent epidemiological investigation on surgical incidence of hydatidosis was used to classify governorates according to their incidence rate. A "global hydatidosis risk score" was calculated for each governorate, combining some parameters related to the hygiene conditions of the population, the literacy rate, the canine density and livestock census.
