[Left-sided appendicitis: description of a rare case in an adult patient diagnosed in Antananarivo].

The purpose of this report is to describe a case of appendicitis in the left iliac fossa. Clinical presentation involved pain in the right iliac fossa with all classical signs of appendicitis. Anomalous location of the appendix was suspected on the basis of a special clinical feature and the patient's family history. Confirmation was achieved by colic contrast enema before surgical treatment.

A malaria control trial using insecticide-treated bed nets and targeted chemoprophylaxis in a rural area of The Gambia, west Africa. 5. Design and implementation of the trial.

A large-scale malaria intervention programme using insecticide-treated bed nets and chemoprophylaxis administered to children was introduced into a rural area of The Gambia. The operation was carried out using the existing primary health care (PHC) service in the region. Training of the village health workers, sensitization of the communities, and implementation of net impregnation and the drug delivery programme are described. This delivery system resulted in over 90% of nets being treated with insecticide and 80% of children receiving over 90% of their tablets during the rainy season. There was considerable variation in the distribution of permethrin on a bed net and between individual nets, which is likely to facilitate the spread of insecticide resistance in the local mosquito populations. Bed nets made from heavier fabrics tended to absorb more insecticide than those made from lighter materials. Four months after dipping, 89% of the insecticide had been lost from treated nets. This was probably due mainly to women washing their nets, an activity carried out on average once every 2 months during the rainy season. The high number of insecticide-treated bed nets in the study area demonstrated that a malaria control programme operated through a PHC system can be implemented successfully.

A malaria control trial using insecticide-treated bed nets and targeted chemoprophylaxis in a rural area of The Gambia, west Africa. 6. The impact of the interventions on mortality and morbidity from malaria.

The effects of insecticide-impregnated bed nets on mortality and morbidity from malaria have been investigated during one malaria transmission season in a group of rural Gambian children aged 6 months to 5 years. Sleeping under impregnated nets was associated with an overall reduction in mortality of about 60% in children aged 1-4 years. Mortality was not reduced further by chemoprophylaxis with Maloprim given weekly by village health workers throughout the rainy season. Episodes of fever associated with malaria parasitaemia were reduced by 45% among children who slept under impregnated nets. The addition of chemoprophylaxis provided substantial additional benefit against clinical attacks of malaria; 158 episodes were recorded among 946 children who slept under impregnated nets but who also received chemoprophylaxis. Chemoprophylaxis reduced the prevalence of splenomegaly and parasitaemia at the end of the malaria transmission season by 63% and 83% respectively. Thus, insecticide-impregnated bed nets provided significant protection in children against overall mortality, mortality attributed to malaria, clinical attacks of malaria, and malaria infection. The addition of chemoprophylaxis provided substantial additional protection against clinical attacks of malaria and malaria infection but not against death.

[Criteria of indication of puncture of amebic liver abscesses. 228 patients].

To clarify the therapeutic role of US-guided in the treatment of amebic liver abscess, three different approach to amebic liver abscess were tested in 228 patients (187 males and 31 females) along 3 years. In a west african endemic area (in Abidjan). All cases were correctly diagnosed by clinical and sonographic findings, and by the pus after percutaneous or chirurgical drainage. The three modes of therapy utilized segregated three distinct group. The first group consisted of 80 patients who were treated medically by metromidazole and ampicillin administered orally. In them, 33 patients have noncollected abscess with a diameter ranged from 2.3 to 12.7 cm (mean 6.6 cm), 23 patients have a collected abscess with a diameter less than 10 cm ranged from 4.1 to 9.7 cm (mean 7.1 cm), 24 patients have a collected abscess with a diameter equal or exceeding 10 cm ranged from 10 to 22.5 cm (mean 14.3 cm). In the second group, there were 124 patients, and they were treated with combined US-guided percutaneous evacuation and medical therapy. In them, 22 patients have a collected abscess with a diameter less than 10 cm ranged from 4.9 to 9.5 cm (mean 7.4 cm), and 102 patients have a collected abscess with a diameter equal or greater than 10 cm (measured 10 cm to 27.5, mean 15.3). There were twenty four patients in the last group, they were treated by open chirurgical drainage because they have an abdominal ruptured abscess. The results with each form of therapy were assessed clinically and by abdominal ultrasound.(ABSTRACT TRUNCATED AT 250 WORDS)

[A study on drinking and problem drinking in tuberculosis patients].

Drinking and problem drinking were studied in 43 tuberculosis patients with the following results. The results of the KAST (Kurihama Alcoholism Screening Test) revealed that 10% of the patients were severe problem drinkers (diagnosed as alcohol dependent syndrome), 7% of the patients had drinking problems and 17% were potential problem drinkers. These percentages are higher than those of the general adult population. In the cases having higher KAST scores, the time between the onset of subjective symptoms and the first medical examination were long, but the time between the first medical examination and diagnosed tuberculosis was short. Severe tuberculosis patients showed higher KAST scores. It was assumed that tuberculosis patients who drink too heavily or are problem drinkers, were apt to put off consulting a physician, and as a result, the condition of tuberculosis would be more severe when they finally did see a physician. In the field of tuberculosis prevention and medical treatment, professionals should pay more attention to drinking and alcoholism. The need to stay sober is important in both preventing relapses and supporting recovery from tuberculosis.

Computed tomography of thoracic aortic dissection: accuracy and pitfalls.

During a 5 year period, 137 patients with suspected acute aortic dissection were screened by CT. The radiologic diagnosis of dissection was made in 54 cases and eliminated in 76. There were seven false-negative CT examinations. Surgical and angiographic correlations or clinical follow-up were obtained with all patients.

Postoperative CT follow-up of aortic dissection.

Computed tomography with contrast enhancement permits noninvasive follow-up of patients treated for aortic dissection. We used CT to examine 52 patients with aortic dissections for up to 14 years postoperatively. The mean interval between surgery and CT was 32 months. Computed tomography demonstrated the aortic graft in 45 patients. Persistent patency of a false lumen was observed in 40 cases. In one case, CT demonstrated extension of the dissection. No rupture or thoracic pseudoaneurysm was noted in our series.

[Fontanel ultrasonography of purulent meningitis in children in Abidjan (Ivory Coast)].

A prospective study of 100 newborns and young babies suffering from purulent meningitis was carried out over a period of 11 months in the radiology department of CHU in Treichville. All the children included in the study were hospitalised in the pediatric department of the CHU. We found cerebral complications in 76% of cases. The most frequent complication was ventricular dilation which occurred in 82.6% of cases. Pericerebral bleeding occurred in 9.3%, cerebral ischemia in 3.5%, brain abscesses in 2.3% and ventriculitis in 2.3% of cases. Our study demonstrated the two important uses of trans-fontanelle ultrasound scans in the study of meningitis: (i) in diagnosis, for the detection of cerebral complications; (ii) in treatment, interventional use of ultrasound makes it possible to evacuate intra-cranial septic fluids.

[Ultrasound scanning of abdominal contusions in children: experience at the Yopougon CHU (Ivory Coast)].

Ultrasound scans were used to study 23 cases of abdominal contusion in children, between January 1992 and December 1993. Thirteen boys and 10 girls were studied. They were all aged between 4 and 14 years, with a mean age of 6 years. The main causes of their injuries were road accidents (12 cases) and play (11 cases). Ultrasound scans were normal in 6 patients and pathological in 17 patients. The most frequently observed injuries were visceral effects (12 cases), almost always associated with hemoperitoneum. In three cases, hemoperitoneum was detected in the absence of visceral effects. The spleen (4 cases) and the liver (4 cases) were the most frequently injured organs. The other injuries detected included renal hematoma, bladder rupture and parietal hematoma. Diagnosis on the basis of ultrasound scans was found to be incorrect in three cases where diagnosis was repeated after the scan. One case involved a blocked perforation of the rectum, one a benign cyst and the other a mesenteric cyst. Despite these misdiagnoses, ultrasound scanning is a highly sensitive and specific method for examination of contusions in children. It is very useful and often sufficient for accurate diagnosis, particularly in units with only modest technical support.
