Chewing gum reduces postoperative ileus after open appendectomy.

HYPOTHESIS: It is suggested that chewing gum may accelerate postoperative intestinal transit recovery. Chewing gum may therefore produce the same result after open appendectomy. DESIGN AND SETTING: Prospective, randomized study in a University teaching hospital. PATIENTS: 46 patients operated on by open appendectomy due to acute catarrhal appendicitis, appendicular abscess and appendicular generalized peritonitis. MAIN OUTCOME MEASURES: Interest was in occurrence of first flatus, first bowel movement, hospital duration and complications. RESULTS: A total of 46 patients were randomly divided into two groups: a chewing gum group (n=23) and a control group (n=23). In the first group, patients chewed sugarless gum for 30 minutes thrice daily until resumption of intestinal transit. Patient demographics, intra-operative, and postoperative care were the same for both groups. Chewing gum was well tolerated by all the patients. The first passage of flatus occurred on postoperative day 2.2 in the gum-chewing group and on day 3.0 in the control group (P < 0.0001). The first bowel movement occurred at postoperative day 2.3 in the chewing gum group and at postoperative day 3.3 in the control group (P < 0.0001). Five complications were noted overall. Hospital stay was shorter in the chewing gum group (4.9 days.) than in the control group (6.7 days), (P < 0.0001). CONCLUSION: Chewing gum ameliorates recovery after open appendectomy by reducing postoperative ileus. It is a cheap and helpful treatment to be recommended in developing countries in Africa.

Implant orthopaedic surgery in HIV asymptomatic carriers: management and early outcome.

BACKGROUND: To the best of our knowledge, no reports currently exist on how to manage HIV infected patients in cases where they present with an absolute indication for implant surgery. The aim of this study was to compare the immediate and early outcome of implant orthopaedic surgery in HIV carriers with less than 500CD4/ml (group A) treated with a protective antiretroviral therapy and prolonged prophylactic antibiotic therapy in one group, and in the other group, HIV carriers with more than 500CD4/ml (group B) and non-HIV carriers (group C) treated conventionally. METHODS: During a 36-month-period, a protocol of screening and subsequent management of HIV carriage was proposed to patients admitted for internal clean trauma or orthopaedic implant surgery in our department. The HIV screening, its confirmation and the CD4 count were carried out by conventional methods. All group A patients were treated with cefuroxime for 10 days and a fixed combination of antiretroviral tritherapy before or just after surgery. Group B and C patients solely underwent surgery with a conventional 1.5g of cefuroxime. The wounds in the three groups were later examined at days 2, 7, 14, 45 and at 3 months. The rates of clinical wound infection were compared using the Fisher exact test; the difference was considered significant if p

[Abdominal gunshot wound: description of 86 cases in Cameroon]. / La plaie abdominale par balle: à propos de 86 observations au Cameroun.

Abdominal gunshot wound (AGSW) is a trauma emergency. The purpose of this report is to describe our experience with managing AGSW largely without modem investigational modalities. Data was collected retrospectively by reviewing the surgical reports and clinical charts of patients admitted to live hospitals dealing with AGSW over a 5-year period. Incomplete files and wounds not involving the abdomen were not included. A total of 86 files were analyzed. Patients ranged in age from 10 to 63 years ivith mean age of 32 years and a sex ratio of 5.5. Most patients (87%) underwent surgical exploration. Laboratory revealed no lesions in 22.5% of cases, minor lesions in 9.5% and major lesions justifying surgical repair in 68%. A total of 86 visceral lesions were found in the patients who underwent surgical exploration. The lesion involved the small intestine in 31.5% of case, colon in 24.5%, liver in 23.5%, spleen in 7%, stomach in 6%, and uterus in 2%. The kidney, pancreas, mesenteries, large momentum, and transverse mescaline each accounted for 1% of lesions. Conventional operative techniques were used with a mortality of 5.5% and morbidity of 4%. Based on our findings we conclude that when investigational tools (CT-scan, peritoneal lavage and laparoscopy) are unavailable prolonged watchful waiting increases the risk of mortality and morbidity in patients presenting AGSW associated with suspicious clinical signs. Prompt surgical treatment improves prognosis but is associated with a high rate of cases showing no lesions.

Bone tumours in Cameroon: incidence, demography and histopathology.

A multicentre analysis was carried out on bone tumours in Cameroon during a 10-year period. Registers and patient records of five pathology laboratories were consulted, and all patients with a histological report of a bone tumour were included in the study. A total of 268 bone tumours were studied and the average incidence was 27 tumours a year, or two per one million inhabitants. Of these tumours 48% were benign, 45% were primary bone cancers and only 6% were metastatic disease. Among the primary malignant bone tumours, osteosarcoma was the most frequent (39%), followed by non-Hodgkin's primary bone lymphoma, fibrosarcoma, chondrosarcoma, and Ewing's sarcoma. Primary site of the metastatic bone tumours was prostatic adenocarcinoma, breast cancer, hepatocarcinoma and thyroid cancer. In Cameroon many bone tumours are not diagnosed due to lack of medical facilities and little awareness among our medical staff. It is likely that the real incidence is at least ten times higher than that shown in our report.

[Stress fracture of the femur: a rare complication of sickle cell disease]. / Fracture de stress du fémur dans la drépanocytose: une complication rare.

A 24-year-old patient with homozygous sickle cell disease developed a stress fracture of the femur. Successive x-rays demonstrated defective ossification and a spontaneous unicortical fracture with no notion of trauma or stressful activities (e.g. sports) followed six months later by a bicortical fracture with displacement and periosteal reaction leading to the diagnosis of stress fracture. This type of fracture has not been reported previously in sickle cell disease. The patient was treated with centromedullary nailing. The follow-up was uneventful. Bone healing was achieved at three months. The patient was pain free and could walk without crutches. Stress fracture is a potential diagnosis in homozygous sickle cell disease patients with defective ossification who present spontaneous pain even when plain x-rays do not visualize an overt fracture. Computed tomography or magnetic resonance imaging should be performed when available. Conventional treatment with nailing provides successful cure with good functional outcome.
