Horizontal root fracture in a maxillary central incisor: restoration after endodontic treatment]

It's about the conservation of a central maxillary incisive, presenting an horizontal radicular fracture, without communication with the intra-oral cavity and after endodontic treatment and fasten down. The post-therapeutic control after 6 months has shown a cicatricial cal formed.     

Oesophageal atresia: Diagnosis and prognosis in Dakar,Senegal

Background:

Oesophageal atresia is a neonatal emergency surgery whose prognosis has improved significantly in industrialised countries in recent decades. In sub-Saharan Africa, this malformation is still responsible for a high morbidity and mortality. The objective of this study was to analyse the diagnostic difficulties and its impact on the prognosis of this malformation in our work environment.

Patients and Methods:

We conducted a retrospective study over 4 years on 49 patients diagnosed with esophageal atresia in the 2 Paediatric Surgery Departments in Dakar.

Results:

The average age was 4 days (0-10 days), 50% of them had a severe pneumonopathy. The average time of surgical management was 27 h (6-96 h). In the series, we noted 10 preoperative deaths. The average age at surgery was 5.7 days with a range of 1-18 days. The surgery mortality rate is 28 patients (72%) including 4 late deaths.

Conclusion:

The causes of death were mainly sepsis, cardiac decompensation and anastomotic leaks.Key words: Esophageal atresia, Diagnosis, Prognosis, Sub-Saharan Africa     

Low awareness of intestinal schistosomiasis in northern Senegal after 7 years of health education as part of intense control and research activities

We evaluated the awareness of and knowledge about intestinal schistosomiasis in a highly infected rural community of northern Senegal where a variety of health information and education activities had taken place for 7 years as a component of different research and control programmes. As the infection had been introduced only recently, an initial 'zero' knowledge can be assumed. Most of the health education activities had been performed with adapted messages through local health and community workers. By a questionnaire, 566 individuals were asked simple questions on symptoms, mode of transmission, the sources of information and health-seeking behaviour. About 86% of the respondents stated that they knew what schistosomiasis was, and 92% that in case of illness they would seek treatment at the health centre. However, only half of the people accurately quoted symptoms associated with intestinal schistosomiasis: diarrhoea, abdominal pain and bloody stools. The majority of respondents realized that the disease was somehow linked with water and (lack of) hygiene, but only 44% of respondents reported water contact as the source of infection. Ultimately, only 30% of the respondents gave adequate answers about both symptoms and mode of transmission. We conclude that even intense and long-lasting education efforts for a specific and straightforward problem as schistosomiasis are not enough to have profound impact on the knowledge of rural traditional communities.     

Epidemiology of the resistance of Mycobacterium tuberculosis to antituberculosis drugs at the main hospital in Dakar, Senegal. A 4-year retrospective study (2000-2003)

A retrospective study was carried out from January?2000 to December?2003 to assess the resistance of Mycobacterium tuberculosis to antituberculosis drugs and the impact of this on the treatment result. Two hundred and two patients' files were studied (average age: 36?years; sex-ratio: 1.7). Pulmonary localisation (85.7%) or extrapulmonary localisation (14.3%). HIV status is negative (71.3%), positive (10.8%) or unknown (17.9%). The overall recovery rate is 60.7% (61.4% in HIV-; 46.1% in HIV+), the rate of treatment failure is 2.7% (1.1% in HIV-; 15.4% in HIV+), the death rate due to tuberculosis is 6.3% (2.3% in HIV-; 23.1% in HIV+), and the rate of patients who disappeared from the system is 30.3% (35.2% in HIV-; 14.2% in HIV+). Hepatotoxicity that occurred during treatment is observed in 14.3% of cases (recovery: 56.2%; failure: 6.2%; lost from the system: 18.8%). Eighty-four percent of patients never received antituberculosis treatment (group?A) versus 15.8% of patients who had already received one or more antituberculosis drugs (group?B). The rates of resistance to isoniazid are 6.4% (A) and 12.5% (B), to rifampicin 1.7% (A) and 12.5% (B), to ethambutol 0.5% (A) and 0% (B), to streptomycin 24.1% (A) and 46.8% (B). The percentage of multiresistant strains is 1% in patients not treated previously and 11% in those who had already received antituberculosis treatment. When the patients are carriers of a strain that is responsive to the treatment administered, the recovery rate is 64.2% versus 46.7% in patients whose strain is resistant to at least one of the treatments administered.     

The traffic elbow. A series of 9 cases

"Traffic elbow" is a condition occurring when high energy trauma involves a patient's elbow resting on the window of the car or completely outside it. This is a prospective study over 30 months of 9 patients with "traffic elbow" and therefore sufferring complex open trauma to the elbow. There were 8 men and 1 woman with a median delay of 4 hours before arrival in hospital. The dominant member was affected in 3 cases. The severity of the lesions, using the Mangled Extremity Severity Score (MESS), was more than 7, comprising lesions corresponding to type 1 of the complex trauma of the superior member (TCMS) in 2 patients and a MESS score of between 3 and 6 corresponding to types 2 or 3 of the TCMS for the other 7 patients. The therapeutic possibilities are limited considering the frequent context of polytrauma. In 4 cases we performed a debridement and external humero-ulnar fixation, in 3 cases a debridement and stabilization with Kirschner's wires completed by a fenestrated cast, and in 2 cases a lifesaving amputation. All patients, except those that had had amputation, developed deep sepsis that resolved after adequate treatment. Assessment of the non-amputee patients according to the Mayo Performance Score, yielded more than 70% of bad results. The authors stress the gravity of these lesions whose prognosis is guarded both concerning mobility of the elbow and the frequent neurovascular complications.
