Transient effect of single dose exposure of Nigerian Bonny-light crude oil on testicular steroidogenesis in Wistar rats is accompanied by oxidative stress.

The folkloric use of Nigerian Bonny-light crude oil (BLCO) in Niger Delta area of Nigeria is a common practice. There is increasing experimental evidence portending the adverse effects of BLCO an environmental toxicant on testicular function. We investigated the effects of single dose of BLCO (800 mg/kg body weight) on the activities of steroidogenic and antioxidant enzymes such as serum follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone, 3 ß-hydroxy-steroid dehydrogenase (3 ß-HSD), 17 ß-hydroxy-steroid dehydrogenase (17 ß-HSD), superoxide dismutase (SOD), glutathione-S-transferase (GST) and glutathione peroxidase (GSH-Px), levels of lipid peroxidation (LPO), glutathione reduced (GSH) and steroidogenic acute regulatory (StAR) protein, in testes of rats. There was a sequential reduction in the concentration of steroid hormones and activities of steroidogenic enzymes with a concomitant decrease in levels of StAR protein, followed by a parallel increase in antioxidant enzyme activities and levels of LPO. These findings revealed inhibitory effects of BLCO on testicular steroidogenesis and the possible role of oxidative stress in testicular dysfunction observed in this study.

In vitro genotoxic and mutagenic evaluation of the aqueous extract of Codiaeum variegatum and its amoebicidal sub-fraction.

ETHNOPHARMACOLOGICAL RELEVANCE: Codiaeum variegatum, grown in many varieties, has been widely used as a houseplant based on its brightly decorative foliage. In addition, a variety of this plant has been used for a long time against bloody diarrhea by the local population in Cameroon. AIM OF THE STUDY: In our previous study, the aqueous extract of this plant and an isolated sub-fraction exhibited significant anti-amoebic activity on axenic culture of Entamoeba histolytica. Due to the medicinal value of these extracts, we promptly initiated to investigate their genotoxic and mutagenic potential in order to assure their safe and rationale usage in traditional healthcare system. MATERIAL AND METHODS: Both extracts were incubated with L5178Y mouse lymphoma cells, primary hepatic cells and HepG2 human hepatocellular carcinoma cells and their genotoxicity and mutagenicity were evaluated by quantifying DNA damage and chromosomal aberrations through comet assay, micronucleus assay and mouse lymphoma mutation assay. RESULTS: The aqueous extract of Codiaeum variegatum is not cytotoxic up to 2000 µg/mL while the amoebicidal fraction is significantly cytotoxic (≤40-55%) on L5178Y mouse lymphoma and HepG2 cells at concentrations higher than 500 µg/mL. Besides, no significant DNA damage and induction of micronucleus formation were identified at concentrations up to 2000 µg/mL. Moreover, the mutagenic potential of these extracts after short (4 h) and long term (24 h) treatment, revealed no significant gene mutation induction. CONCLUSION: The aqueous extract of Codiaeum variegatum and the amoebicidal fraction SF9B are neither genotoxic on non-competent or metabolic competent cell lines, nor mutagenic in mouse lymphoma mutation assay and therefore they could be safely used at lower doses for medicinal purpose.

[Surgical abdomen caused by traditional treatment. Five-case report in teaching hospital Yalgado Ouédraogo of Ouagadougou]. / Les abdomens chirurgicaux dus au traitement traditionnel. À propos de cinq cas au Centre hospitalier Yalgado Ouédraogo de Ouagadougou.

The traditional products used to treat some pains can cause serious complications of which surgical abdomen. We listed in two years five cases of surgical abdomen complicating a traditional treatment in the service of digestive and general surgery of the hospital complex Yalgado Ouédraogo. There were two men and three women with an average age of 34,4 years. These traditional products were used to treat constipation, sexual impotence, sterility and to "posses" her husband. Oral and rectal routes were used by one and three patients respectively, another patient used triple routes (oral, rectal and vaginal). The digestive lesions were in the upper tract in one case (gastric phytobezoar), two patients presented acute intestinal occlusion and two others acute generalized peritonitis. All the five patients underwent laparotomy. Two patients died in immediately post-operative course. The prevention of severe surgical complications of the digestive tract induced by traditional treatments has to be broadcasted through information, education and communication.

[Traditional bonesetter's gangrene of limb in children in Regional Hospital of Kaolack (Senegal)]. / Gangrène de membre à la suite d'un traitement traditionnel de fractures par attelle en bambou chez l'enfant à l'Hôpital régional de Kaolack (Sénégal).

Little published data exist on the morbidity and mortality associated with poor trauma care in developing countries. This report highlights our experience with iatrogenic limb gangrene related to fracture management by traditional bonesetters. Children with bonesetter's gangrene were identified from a prospectively recorded paediatric surgery database at the Regional Hospital of Kaolack in Central Senegal. 21 children were treated for bonesetter's gangrene during a 18-month period (January 2007 up to June 2008). The average age was 10 years (range, 5 to 15 years). Bonesetter's gangrene was more common in boys (90.5%) and occurred almost exclusively in children from rural areas where access to health care was limited. 16 children underwent proximal extremity amputation. Complications included one case of tetanus. Bonesetter's gangrene is a preventable complication that results from a failure of child health planners to recognize the importance of basic trauma care. Management of fractures should be considered an essential component of child health programs in developing countries.

Pudendal thigh flap in the treatment of acquired gynatresia from caustic pessaries.

OBJECTIVES: To evaluate the use of vaginoplasty with the pudendal thigh flap in patients with gynatresia caused by herbal pessaries in a multidisciplinary context. METHODS: The study included patients with herbal-pessary-induced vaginitis and gynatresia. Surgical treatment consisted of vaginoplasty with the pudendal thigh flap; patients with associated fibroids had a myomectomy during the same setting. The severity of the stenosis and the outcome after surgery were assessed with rating scales devised for the present study. RESULTS: The study included 21 patients (mean age 36.05 ± 1.69 years, range 18-50 years). The most common reason for herbal pessary use was fibroids with infertility. Prior to presentation, most patients had already undergone a median of 2 procedures involving vaginal adhesiolysis and dilatations without improvement. In total, 17 (80.9%) patients underwent surgery. Of these, 6 (35.3%) presented with both fibroids and gynatresia. Before surgery, all patients had poor sexual function with apareunia. Postoperatively, 11 (64.7%) patients reported painless sexual intercourse. CONCLUSION: Joint management by plastic surgeons and gynecologists using the pudendal thigh flap for vaginoplasty in caustic gynatresia resulted in a functional vagina. Simultaneous myomectomy and vaginoplasty in patients with fibroids and gynatresia was safe.

Evaluation of bloodsucking arthropod bite as possible risk co-factor in Human herpesvirus-8 transmission route.

Human herpesvirus-8 non-sexual transmission occurs primarily from mother-to-child. The viral load in saliva is higher than in other human fluids. Moreover, there is evidence that bloodsucking arthropod bites induce an inflammatory/immune response that facilitates viral replication. We aim to explore possible risk factors in mother-to-child HHV-8 transmission associated with traditional methods which involve the use of saliva to relieve the irritation and skin reaction caused by arthropod bites. We administered questionnaires to 2244 children from several African countries and Italy. Descriptive statistics and logistic regression were used in the analysis of the answers to evaluate the relationships between the use of traditional methods and other risk factors. The use of traditional methods is high in Cameroon (63.0%) and Uganda (39.9%), intermediate in Senegal (26.7%) and Italy (21.7%), low in Madagascar (6.7%). Statistical analyses show significant direct relationships between the use of traditional methods, skin reactions to the bite and their duration in Cameroon, Uganda and Senegal. The use of saliva and herbs applied by the mothers on the child's skin, is a common habit in Africa. If this practice plays a role in the HHV-8 transmission, then, it could provide the basis for interventions capable of reducing the health impact of the infection in children in tropical areas.

Beliefs about the causes of cervical cancer in Botswana: implications for nursing.

BACKGROUND: Cervical cancer is the most common cause of cancer mortality and morbidity for women in Botswana. Yet, little is known about what women believe to be the causes of the disease. AIM: This paper presents data on factors women in Botswana believe are responsible for the high incidence of cervical cancer in their country. Data were part of a larger study that explored knowledge and perceptions about cervical cancer and Pap smear screening from the perspectives of the clients and the healthcare providers. METHODS: The study that generated the data included 30 women of all socio-economic levels, recruited by network sampling. The women's ages ranged from 31 to 54 years. Demographic data were analysed descriptively. Individualized interview data were content-analysed. FINDINGS: The identified causes of cervical cancer were classified as cervical irritants and non-irritants. The most commonly cited cervical irritants were vaginally inserted chemical agents and traditional medicine. DISCUSSIONS: Participants identified vaginally inserted chemical substances and traditional medicines as possible explanations for the high incidence of cervical cancer in Botswana. They reported that women used these substances for sexual and hygienic purposes. Although these factors are believed to be the causes of cervical cancer and have not yet been medically acknowledged, verbal reports suggest that their use is problematic. CONCLUSION: There is a need for health education and for further research to affirm women's beliefs about the harmful effects of intravaginal agents.

Multiple digital gangrene arising from traditional therapy: a case report.

BACKGROUND: Traditional medicine has being advocated as an alternative to Orthodox medicine in Nigeria despite, its reported adverse effects. OBJECTIVE: To report an unusual complication of traditional therapy. METHODS: A 20-year-old house-wife who was bitten by a crawling insect presented to a hospital with complaints of swollen body and pain in three digits. After clinical evaluation and investigations, she had both medical and surgical intervention. RESULTS: Two weeks following an insect bite, the patient noticed periorbital and bilateral leg swellings. She sought help from a traditional medicine practitioner who incised and tied the affected digits for three days. He repeated the cycle thrice. She had generalized oedema, massive proteinuria, hypoalbuminaemia, hypercholesterolaemia features consistent with a diagnosis of nephritic syndrome. There was gangrene of the left middle finger and both index toes. Oedema responded to diuretics, lisinopril and low salt diet. She had surgery for the gangrenous digits. CONCLUSION: Development of gangrene is an unusual finding in nephrotic syndrome. It occurred in this case as an aftermath of traditional medical intervention. This report reiterates the danger of this form of medical practice and the need for measures to protect the populace to be put in place.
