[Endovascular treatment of chronic mesenteric ischemia]. / Traitement endovasculaire des angors mésentériques.

INTRODUCTION: Atherosclerosis occurring in the digestive arteries is rare and often asymptomatic. When it becomes symptomatic, surgical care is indicated. Conventional procedures are giving way to improved endovascular techniques applied to the mesenteric arteries. The aim of this single-center study was to evaluate short- and mid-term outcome after endovascular revascularization of the mesenteric arteries. METHODS: We report a retrospective study about patients who underwent endovascular treatment of chronic mesenteric ischemia between 2013 and 2018. RESULTS: Our population consisted of 10 patients. The average age was 60 years [range 45-78]. Clinical symptomatology associated abdominal pain and weight loss. All patients underwent computed tomographic angiography (CTA). Severe stenosis (>70%) involved the superior mesenteric artery (SMA) in ten cases, the celiac trunk in four cases and the inferior mesenteric artery in three. The procedure was performed under local anesthesia in all cases. The superior mesenteric artery was revascularized in all cases and the celiac trunk in two. Transluminal angioplasty was followed by deployment of a stent in all cases. The postoperative course was satisfactory. Outcome was good with all patients being symptom-free at one month. Our average follow-up was three years [range 1-5]. All patients underwent a Duplex ultrasound every six months. Recurrence of symptomatology was reported in two patients at 18 months and 24 months. The first patient underwent CTA that showed superior mesenteric artery and celiac trunk stent stenosis. The patient underwent a second transluminal angioplasty with a drug eluting balloon. The second patient was admitted to the emergency room for acute mesenteric ischemia related to acute thrombosis of the superior mesenteric artery stent. Laparotomy enabled extensive resection of the small bowel and aorto-mesenteric venous antegrade bypass, but the patient died the same day. CONCLUSION: Endovascular treatment has an important role to play in the management of chronic mesenteric ischemia. It is associated with a high rate of technical success. Patients should be carefully followed-up because of the mid-term risk of recurrent symptoms associated with intra-stent restenosis or thrombosis.

[Post-traumatic carotido-jugular fistula: Case report and review of the literature]. / Fistule carotido-jugulaire post-traumatique : à propos d'un cas opéré.

The neck, being not protected by skeleton, is vulnerable to external trauma and injury which can involve blood vessels, muscles, nerves, and trachea. Carotid injuries can be potentially life-threatening by hemorrhage and stroke. We present a case of a 26-year-old manual worker who presented a neck injury caused by a metallic projectile. The injury involved the right common carotid artery with an internal jugular vein fistula, and tracheal damage. The patient was managed with surgical repair of the tracheal lesion, reconstruction of the carotid section using a PTFE graft bypass, and ligation of the internal jugular vein. In the immediate postoperative period, the patient presented with no neurological deficits, but he did develop a pulmonary infection that resolved with antibiotic therapy. The follow-up is now 3months. The patient is doing well without any neurological disorder.

Human papillomavirus genotypes and HPV-16 variants distribution among Tunisian women with normal cytology and squamous intraepithelial lesions.

BACKGROUND: Little is known about the epidemiological characteristics of papillomavirus (HPV) infection among North African countries. Herein, we conducted a molecular epidemiological study to investigate prevalence of HPV type and HPV-16 variants among cervical-screened unvaccinated Tunisian women. METHODS: Cross-sectional study was performed on 494 Tunisian women visiting Women's Healthcare Centers. HPV-DNA detection was carried out on cervical samples using real-time polymerase chain reaction. HPV genotyping and HPV-16 variants were characterized by direct sequencing of L1 viral capsid gene. RESULTS: The overall HPV prevalence was 34% (95% CI: 30-38%) with significantly higher prevalence among women with squamous intraepithelial lesions (SIL) than those with no intraepithelial lesions (NIL) 84% (95% CI: 76-92%) and 24.5% (95% CI: 20-29%) respectively. The distribution of HPV prevalence according to women's age shows a U-shaped curve and the highest HPV prevalence rates were observed among the youngest (≤25 years; 51.2%, 95% CI: 37-67%) and the oldest women (>55 years; 41.7%, 95% The HPV-16 prevalence was 32.8% (95% CI: 22-45%) among women with SIL and 9.2% (95% CI: 6-12%) among women with NIL. Whereas, the HPV-18 prevalence was 1.3% (95% CI: 0-5%) among women with SIL and 0.3% (95% CI: 0-1%) among women with NIL. Among HPV-16 positive women, European lineage (E) was identified as the predominant HPV-16 variant (85.7%, 95% CI: 76-95%). The frequency of E variant was lower among SIL than among NIL women (81%, 95% CI: 64-99%, and 88%, 95% CI: 77-100%, respectively). Conversely, the African-2 variant frequency was higher among SIL than among NIL women (18%, 95% CI: 1-36% and 6%, 95% CI: 2-14%, respectively). In multivariate analysis, young age was the only risk factor that is independently associated with HPV infection. Moreover, HPV infection and menopause were both found to be independently associated with SIL and HSIL. CONCLUSION: HPV DNA testing should be proposed to young and menopausal Tunisian women. Considering HPV prevalence, only 13% of the Tunisian women could be protected by the bivalent HPV vaccine. These results may be helpful for designing an adapted HPV testing and vaccination program in Tunisia.

Morning melatonin ingestion and diurnal variation of short-term maximal performances in soccer players.

Aim Very few studies have investigated the temporal specificity of melatonin (MEL) ingestion upon short-term maximal athletic performances. The aim of the present study was to explore the effect of morning MEL ingestion on cognitive and physical performances measured in the afternoon. Methods Twelve soccer players from a Tunisian squad (17.9 ± 1.3 years, 1.74 ± 0.06 m and 62.0 ± 8.8 kg) participated in the present study. They performed two testing sessions at 08:00 h, 12:00 h and 16:00 h after either MEL (5mg) or placebo (PLA) ingestion, in a randomized order. During each period, the participants performed the following cognitive and physical tests: reaction time and vigilance tests, medicine-ball throw (MBT), five jumps, handgrip strength (HG), and agility tests. Results cognitive and physical performances were significantly higher at 16:00 h compared to 08:00 h during the two conditions (p < 0.05). Moreover, performances of MBT and HG were lower in the morning with MEL in comparison to PLA (p < 0.05). However, MEL ingestion did not affect physical and cognitive performances measured at 12:00 h and 16:00 h. Conclusion morning MEL ingestion has no unfavourable effect on afternoon physical and cognitive performances in soccer players.

Gene frequencies of the HPA-1 to -6 and -15 human platelet antigens in Tunisian blood donors.

Gene frequencies of mainly human platelet antigens (HPA) -1 to -6 and -15 were determined in 116 Tunisian blood donors. The distribution of HPA-1, -3 and -5 systems approach those found in other Maghrebian populations. Tunisians have the highest frequency of HPA-1b and -5b alleles. The distribution of HPA-1a allele and HPA-4, -6 and -15 systems is similar to Caucasians. Phylogenetic study using the neighbor-joining method and principal component multivariate analysis demonstrate that Tunisians are more closely related to western than to eastern Mediterraneans. This immunogenetic study highlights the relatedness between Mediterranean populations and will serve as a baseline study for future clinical research involving platelet disorders among Tunisians.

[Morbidity diagnosed in the general medicine public structures in Tunisia]. / La morbidité diagnostiquée dans les structures publiques de médecine générale en Tunisie.

The study of morbidity in general medicine is very useful in order to adapt training curricula to the reality of medical practice in the first degree. The objective of this work was to describe the morbidity charted in general medicine in Tunisia's Sousse region. It consisted of a prospective and descriptive study involving six basic health centres in Sousse and was conducted over the course of 30 randomly selected days during the year 2000. There were 4022 consultations included in the study which were described according to the SOAP plan. The coding of the charted diagnoses was carried out according to the International Classification of Primary Care (CISP). There were 98% of the consultants who were self-referred and 84% of the consultations corresponded to new cases. The consultants' sex-ratio was 0.5 in favour of females with an average age of 27 years. There were 4,597 diagnoses noted utilising 336 codes from the CISP classification system. The "Respiratory" chapter took the first place on the list (39.6%) followed by the "Circulatory" chapter. The "Top 30" list of the most often charted diagnoses totaled 72% of the consultations among which the three most frequent health problems were pharyngitis (14.4%), acute bronchitis (8.3%) and arterial hypertension (7.4%). This study demonstrates that the practice of general medicine is characterised by instinctive first solutions and versatility. The predominance of cardiovascular and respiratory illnesses illustrates the double burden of morbidity which is faced by Tunisian general medicine practitioners. The "Top 30" list should serve as basis for planning pregraduate and continuing medical training.
