Molecular detection and MST genotyping of Coxiella burnetii in ruminants and stray dogs and cats in Northern Algeria.

Aiming at identifying the reservoir and contamination sources of Coxiella burnetii in Northern Algeria, we investigated the molecular presence of the bacterium in 599 samples (blood, placenta, liver, spleen, and uterus) collected from cattle, sheep, dogs and cats. Our qPCR results showed that 15/344 (4.36%) blood samples and six/255 (2.35%) organ specimens were positive for C. burnetii. In cattle, three (4%) blood and liver samples were positive. In sheep, one blood (1.19%) and 3 (8.57%) placenta samples were positive. At the Algiers dog pound, 8 (10%) and 3 (5%) blood samples were qPCR positivein dogs and cats, respectively. In addition, MST genotyping showed that MST 33 was present in cattle and sheep, MST 20 in cattle,andMST 21 in dogs and cats.

Coxiella burnetii infection with women's febrile spontaneous abortion reported in Algiers.

We investigated Q fever infection in Febrile Spontaneous Abortions in women by using a serologic method (Immuno-Fluorescence Assay, IFA) and a molecular method (real-time quantitative PCR, qPCR) in Obstetric-Gynaecology (OB-GYN) services in two hospitals in Algiers. We included in the case group 380 women who experienced Febrile Spontaneous Abortion; the control group comprised 345 women who gave birth without any other infections or complications. Among the 725 women included, antibodies against Coxiella burnetii were detected by IFA in three (03) cases patients; all control group samples were IFA negative. In other hand, only four (04) placental samples among the case group came back with q PCR positive for IS1111 and IS30a too. A relationship between C. burnetii infection and febrile spontaneous abortion exists in OB-GYN services in Algiers.

Pyridoxine-dependent epilepsy: A novel mutation in a Tunisian child.

Pyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive metabolic disease characterized by seizures in neonates or infants, which is unresponsive to antiepileptic drugs but controlled by pyridoxine. Without prompt treatment, continued seizures and severe encephalopathy result. Mutations in the ALDH7A1 gene encoding α-amino-adipic semialdehyde (α-AASA) dehydrogenase (antiquitin) have been identified as the cause of PDE. We report on a novel ALDH7A1 mutation in a Tunisian child with PDE.

The origin of the dorsal scapular artery: anatomic variations and surgical applications.

The dorsal scapular artery (DSA) can be either a direct branch of the subclavian artery (SCA), or a branch of the transverse cervical artery (TCA). In mandibular reconstruction, when a free flap is contraindicated a pedicled scapular flap has been described vascularized by the DSA. During the dissection of this flap, there is a risk of lesion of the TCA, which could be fatal to the flap if the DCA is a branch of the TCA. To evaluate the frequency of this anatomic situation, a dissection and radiologic study has been performed. 50 anatomic dissections on fresh cadavers and 93 arteriographies from 47 patients have been studied, to determine what was the DSA origin. In our dissections we found the origin of the DSA was a type I origin in 19 cases (38 %), a type II in 19 cases (38 %) and a type III in 12 cases (24 %). In our radiologic study, the DSA and the TCA had a common origin from the SCA (Type I) in 57/93 cases (61.3 %), the DSA was a direct branch of the SCA and the TCA (type II) in 22/93 cases (23.7 %), the DSA and the TCA had a common origin from the TCT (type III) in 14/93 cases (15 %). The DSA is coming from the TCA in 1/5 cases. A careful dissection of this flap in the subclavian area is necessary in all cases, a preoperative arteriography could be proposed to limit the risk of pedicle injury.

[Acute disseminated encephalomyelitis in Tunisia: Report of a pediatric cohort]. / Encéphalomyélite aiguë disséminée en Tunisie: étude d'une cohorte pédiatrique.

INTRODUCTION: Acute disseminated encephalomyelitis (ADEM) is an inflammatory, demyelinating disorder of the central nervous system whose clinical features, management and outcome are incompletely understood in Tunisian population. OBJECTIVE: To describe clinical, neuroimaging and laboratory features; treatment and outcome in a cohort of Tunisian children with ADEM. METHODS: We conducted a retrospective review of the medical records of all children attending the Department of Child and Adolescent Neurology (Tunis) with ADEM between 2005 and 2015. Clinical, neuroimaging and laboratory features, therapeutic data and outcome were analyzed. RESULTS: There were 15 children (7 males and 8 females). The mean age at onset was 6.9 years. Thirteen (86.6%) patients had a prodromal event. The onset of neurological symptoms occurred within 17.6 days (4-30). Limb weakness was the most common presenting symptom (53.3%). Extrapyramidal syndrome was noticed in 6 patients (40%). Initial MRI showed a deep gray matter involvement in 7 cases (46.6%). Gadolinium enhancement at acute stage was observed in only 2 patients (13%). Cerebrospinal fluid findings did not show intrathecal oligoclonal bands. The use of high-dose IV methylprednisolone followed by oral steroid taper was associated with rapid recovery. Additional treatment with intravenous immunoglobulin was necessary in 2 patients. Complete recovery was obtained in 11 patients (73.3%). A monophasic course was noticed in 14 cases. Only one patient (5%) developed multiple sclerosis. CONCLUSION: The high frequency of prodromal events and extrapyramidal syndrome in addition to the low rate of gadolinium enhancement at acute stage seem to be the main features in our patients. Larger ADEM multicenter cohort studies in Tunisia and North Africa could provide more detailed information about this entity.

Evaluation in usual practice of the bevacizumab-FOLFIRI combination for the first-line treatment of patients with unresectable metastatic colorectal cancer treated in 2006: focus on resected patients and oncogeriatrics: AVASTIN OUEST cohort of the Observatory of Cancer of the Brittany and Pays de la Loire Areas (Observatoire dédié au Cancer Bretagne / Pays de la Loire).

BACKGROUND: In 2006, bevacizumab, a targeted therapy agent was combined with FOLFIRI for the firstline treatment of patients with unresectable metastatic colorectal cancer. METHODS/RESULTS: A study on a homogenous series of 111 patients from the Brittany and Pays de la Loire areas who received bevacizumab-FOLFIRI as first-line treatment in 2006 showed the following results: 51 responses, 29 stabilisations, 21 progressions and 10 cases of toxicity prior to assessment. Median overall survival (OS) was 25.1 months and median progression-free survival was 10.2 months. Surgery secondary to treatment tripled median OS which reached 59.2 months in resected patients versus 18.8 months in unresected patients. Comparison of patients aged more or less than 70 years showed no differences in terms of benefits or risks. CONCLUSION: Bevacizumab-FOLFIRI could be administered as part of a routine care protocol to elderly patients previously evaluated by a geriatric assessment and validated by a multidisciplinary staff.

En 2006, bevacizumab-FOLFIRI représente la thérapie ciblée administrable dès la première ligne chez les patients porteurs d'un cancer colorectal métastatique non opérable. Une série homogène de 111 patients colligés en région Bretagne et Pays de la Loire ayant reçu du bevacizumab- FOLFIRI en première ligne en 2006 révèle les résultats suivants: 51 réponses, 29 stabilités, 21 progressions et 10 toxicités avant évaluation. La médiane de survie globale (OS) est de 25,1 mois et la médiane de survie sans progression (PFS) de 10,2 mois. Dans le cas d'une chirurgie secondaire, l'OS médian triple de 18,8 mois chez les patients non réséqués versus 59,2 mois ceux réséqués. En comparant les sujets âgés de plus et de moins de 70 ans, aucune différence n'a été mise en évidence en termes de bénéfice ou de risque. Bevacizumab-FOLFIRI pourrait être administré en pratique courante chez les personnes âgées sous couvert d'une évaluation gériatrique et d'une approche multidisciplinaire.

[Epidemic of rubella encephalitis]. / Encéphalite rubéolique : observation récente d'une fréquence inhabituelle.

Rubella is a mild viral illness in children. Rubella encephalitis is an extremely uncommon complication of rubella affecting unvaccinated children, aged between 5 and 14 years. From May to June 2011, we observed 9 cases of rubella encephalitis diagnosed during an epidemic of rubella. All were previously healthy (8 boys and 1 girl). None of them had received rubella vaccine. The mean age was 11.6 years. The onset of neurological symptoms occurred within 1-5 days after the typical rush and was associated with seizures and altered consciousness in all cases. The presence of serum immunoglobulin M antibody against rubella virus was demonstrated in all patients. EEGs showed slow wave activity in all patients and brain MRI was normal in the 9 cases. Full recovery was obtained in all patients. However, 4 of them required intensive care unit referral. Acute encephalitis is an extremely rare complication of rubella. The main neurological findings are headache, ataxia, and hemiplegia. Epileptic seizure and altered consciousness are rarely observed. Rubella encephalitis is generally self-limiting with about 80% recovery rate with no sequelae. However, severe courses have been reported. These cases illustrated the potential severity of rubella and they should be prevented by encouraging widespread early childhood vaccination. In Tunisia, rubella encephalitis has been reported once previously and vaccination against rubella virus has only recently been included in the national vaccination program, prescribed only for adolescent females. Following this rubella epidemic, vaccination strategies in Tunisia have been revised.

[Congenital stenosis of interventricular foramina revealed by recurrent intracranial hypertension]. / Une sténose congénitale des foramens interventriculaires révélée par une hypertension intracrânienne à rechute.

Non-tumoral stenosis of interventricular foramen is a rare clinical condition. It can be either unilateral, causing monoventricular hydrocephalus, or bilateral leading to biventricular hydrocephalus. The pathophysiology of this misdiagnosed entity remains controversial. The non-tumoral stenosis of interventricular foramen can be either acquired or congenital. The latter usually manifesting with a neonatal hydrocephalus. We report a case of congenital bilateral stenosis of interventricular foramen, in an 8-year-old girl, revealed by recurrent intracranial hypertension. Diagnosis was relied on 3D-CISS sequences MRI. The child showed full recovery after neuroendoscopic septal fenestration and ventriculo-peritoneal shunt.

[Reasons for using emergency departments of major hospitals in Greater Tunis]. / Motifs du recours aux services d'urgence des principaux hôpitaux du Grand Tunis.

Tunisia, similar to many countries, has a problem of overcrowding of the emergency departments (ED). This study aimed to analyse the reasons for using EDs, and to describe the seriousness of the attendees' condition and their itinerary before their arrival at ED. This cross-sectional study in 2009 was conducted in ED of 4 hospitals in GreaterTunis and targeted 1058 patients of both sexes, aged 18 years, with stratification according to time of day of presentation to ED (morning, afternoon and evening). Information was recorded on the sociodemographic characteristics of the study participants, reasons for choosing ED, time of and reason for consultation, diagnosis and severity of illness. Over half the patients (52.5%) were male and the mean age was 46.0 (SD 18.1) years. The main reasons for choosing the ED were: speed (54.0%) and ease of access (47.7%) of ER and occurrence of an acute episode (26.4%). Patients with serious illness accounted for only 6.3% of those interviewed. Implementation of good practices and better coordination between public and private services and the ED are needed to reduce unnecessary visits to ED.

Reasons for using emergency departments of major hospitals in Greater Tunis

Tunisia, similar to many countries, has a problem of overcrowd ing of the emergency departments [ED]. This study aimed to analyse the reasons for using EDs, and to describe the seriousness of the attendees' condition and their itinerary before their arrival at ED. This cross-sectional study in 2009 was conducted in ED of 4 hospitals in GreaterTunis and targeted 1058 patients of both sexes, aged >/= 18 years, with stratification according to time of day of presentation to ED [morning, afternoon and evening]. Information was recorded on the sociodemographic characteristics of the study participants, reasons for choosing ED, time of and reason for consultation, diagnosis and severity of illness. Over half the patients [52.5%] were male and the mean age was 46.0 [SD 18.1] years. The main reasons for choosing the ED were: speed [54.0%] and ease of access [47.7%] of ER and occurrence of an acute episode [26.4%], Patients with serious illness accounted for only 6.3% of those interviewed. Implementation of good practices and better coordination between public and private services and the ED are needed to reduce unnecessary visits to ED

[Cost effectiveness analysis of screening strategies for cervical cancer in Tunisia]. / Analyse coût-efficacité des stratégies de dépistage du cancer du col utérin en Tunisie.

We aimed to identify the most appropriate screening strategy for cervical cancer (periodicity of 3, 5 or 10 years) for Tunisia, taking into consideration the incidence of the disease, costs of screening and economic implications. We simulated follow-up of a fictitious cohort of 1 million women 35-39 years over 30 years. Computation of yearly medical care costs was based on data from medical files of patients diagnosed with cervical cancer in 2004 at the National Institute of Cancer, Tunis. For a 60% coverage level of screening, cervical cancer reduction would be 49.2% for a 3-year periodicity. The reduction would be 40.3% and 33.1% for 5 and 10 years periodicity respectively. Considering cost-effectiveness, 10-year screening gave the lowest annual cost to avoid 1 cervical cancer case.

[Exclusive breastfeeding and mixed feeding: knowledge, attitudes and practices of primiparous mothers]. / Allaitement maternel exclusif et allaitement mixte: connaissances, attitudes et pratiques des mères primipares.

We assessed the knowledge attitudes and practices of primiparous women with regard to exclusive breastfeeding and the use of formula milk. A total of 260 women were interviewed and the results showed that 41.5% of the women breastfed exclusively while 58.5% bottle-fed only or did so together with breastfeeding. Of those who breastfed, 43.0% did not do so soon after giving birth and did not know about colostrum. Overall, the knowledge, attitudes and practices of the mothers were unsatisfactory concerning the golden rules for successful breastfeeding, the ideal duration of exclusive breastfeeding and the food to include when introducing complementary feeding. This might be due to a low level of schooling and information, hence the need for improving strategies for maternal care during the antenatal and postnatal periods.

[Breast cancer in Tunisia: epidemiologic characteristics and trends in incidence]. / Cancer du sein en Tunisie: caracteristiques epidemiologiques et tendance evolutive de l'incidence.

The goal of this study is to analyze certain epidemiologic characteristics of breast cancer in Tunisia and to foresee the consequences that will arise from the trends in incidence of this cancer. Data obtained from the North-Tunisia Cancer Registry (NTCR) and from the Salah AZAIZ Institute (SAI) Registry is used to estimate the different incidence rates and to compare these rates with those of other countries. In 15 years the crude incidence rate for breast cancer in the North Tunisia almost doubled to reach 21.5 cases/100,000 women per year during 1994-1998. The high rate of this cancer among women younger than 35 years (11%) could be related to a relatively low incidence among post-menopausal women. The clinical profile of breast cancer remains quite alarming: 40.2% of cases have a tumor with a clinical diameter equal or greater than 5 cm. Birth cohort effect, also know as the generation effect, is expected to lead to an increase of cancer incidence in the future. The rather high number of young cases is a source of additional cost on social and financial level. The priority is now to solve the problem of late diagnosis it has aggravated the prognosis of this cancer in Tunisia.
