[Recurrence of hydatid cyst of liver: predictive factors: Tunisian experience]. / Les facteurs prédictifs de récidive du kyste hydatique du foie : l'expérience tunisienne.

Cystic echinococcosis is a public health problem. Surgery represents the basic treatment and the surgeon is regularly faced with the choice of the appropriate surgical procedure (radical versus conservative surgical approach). The conservative procedure is safe and easy but can lead to a recurrence in the site of residual cavity. The aim of this study was to evaluate the predictive factors of the recurrence of hepatic hydatid cysts, to optimize surgical management and to implement preventive measures. The current retrospective study included 391 patients with hepatic hydatid cysts operated at our institution from 1996 to 2006. The diagnosis of recurrence was suspected by radiological survey and confirmed at laparotomy. The univariate study of predictive factors of recurrence was based on the Fisher test and the multivariate one on the logistic regression model. The recurrence rate reached 12% in our study with an average period of 50 months. Univariate analysis showed that the predictive factors of recurrence were: the rural origin of patients, the voluminous cysts larger than 7 cm, and unilocular hydatid cyst. Multivariate analysis showed that only voluminous cysts and unilocular ones were the predictive factors of recurrence. The unilocular and voluminous hydatid cysts represent the cysts that relapse frequently because of their immunogenic character and the presence of exocysts in the pericysts. This is very important for the therapeutic strategy the main aim of which is to prevent the recurrence.

[Smoking dependence and symptoms of anxiety and depression among Tunisian smokers]. / Dépendance tabagique et troubles anxio-dépressifs chez le fumeur tunisien.

INTRODUCTION: The aim of this study was to describe the incidence of depression and anxiety, and their relationship with smoking dependence, in patients attending a Tunisian smoking cessation clinic. METHODS: We studied 72 Tunisian smokers attending the smoking-cessation clinic at the Charle Nicolle Hospital in Tunis. Nicotine dependence was assessed by the Fageström Test for Nicotine Dependence. Anxiety and depression symptoms were measured using the HAD (Hospital Anxiety Depression) Scale. RESULTS: The prevalence of anxiety and depression was 22.9% (16 patients) and 20% (14 patients) respectively with four patients (7.1%) exhibiting symptoms of both. Overall, 50% of the group had emotional morbidity with high HAD scores for depression or anxiety, or both. Smokers with symptoms of anxiety and/or depression had higher physical and psychological dependence, smoked more at times of stress, had a reduced quitting rate and endured more withdrawal symptoms than those smokers without anxiety or depression. CONCLUSIONS: The data of this survey from Tunisia, a country that has just put in place a tobacco control strategy, underline the high rates of anxiety and depression that exist in patients attending a smoking cessation clinic. It confirms the association between anxio-depressive disorders and a high level of smoking dependence.
