To evaluate the pattern of regression of severe sciatica and pain in the low back over 3 months in HIV infected patients in whom monosegmental lumbar macrodiscectomy was performed for lumbar disc herniation. There are very few reported studies, which have been carried out to evaluate the outcome of lumbar discectomy in HIV positive patients. This was a prospective study conducted from January 2004 to December 2006. Patients included were those who knew their HIV serological status before the first consultation. Patients with previous spinal surgery, multilevel lumbar disc herniation, or any neurologic deficit were excluded. The intensity of pain was assessed by the visual analog scale during regular postoperative follow up. Seventy-seven patients suffering from severe sciatica were included; 9 were HIV positive and 68 were HIV negative. In the HIV positive group, the sex ratio was 2:1, and 8 had severe pain in the low back whereas in the HIV negative group, 44 had severe pain in the low back. At 3 months, sciatica relief (VAS <4) was recorded in 66.6% of HIV positive patients and in 70.6% of HIV negative patients. Relief of pain in the low back (VAS <4) was respectively 50.0% and 55.1% in both groups. The pattern of pain regression during the follow-up period was similar in both groups.

They constitute a risk for pollution of the environment and a vector of germ propagation. This study aimed at analyzing the circuit of waste products and their management in the regional hospital of Ngaoundere. This was a descriptive cross-sectional study going from September 1st to November 30th, 2016. 65 personnel participated to the study. 40 % of them were nursing auxiliary. 49% of the participants knew the selection approach of waste products. Waste products were eliminated by incineration in a hole in an archaic manner or by burying or given to family at their request, for elimination. Liquid wastes were discharged in bidets (75.4%) or in sewers (4.6%) or they were led directly to the evacuation system of used waters. We conclude that the management of waste product in the regional hospital of Ngaoundere is a majo...

The abdominal wound stabs are wounds located between the diaphragm and the pelvic cavity whatever the opening of entry. The purpose of this study is to highlight the diagnostic and therapeutic problems in order to improve and ensure their effective care. Methods. We carried out a retrospective descriptive study of 10 years (2005-2014) which compiled 306 cases of abdominal stab wounds registered in the Regional Hospital of Ngaoundere. Results. Most of the patients were male with a rate of 86% and mostly aged between (20-29 years) with a percentage of 45.7%. 48 out of 306 registered cases were penetrating wounds stab either 15.7% and were systematically operated. Generally, the weapon used was knife with a frequency of 194 for a rate of 63.4%. Occurrence of circumstances was dominated by holdup (55.9%). Intra-abdominal lesion was clinically evident at the existence of hemorrhagic shock, hem peritoneum and evisceration. In a precarious situation like that of the regional ...

Nous decrivons un nouveau-ne presentant des bosses du scalp, massives, bilaterales, au decours d’un accouchement vaginal eutocique. Le pronostic vital a ete menace par une anemie severe et une coagulopathie secondaire. Le patient a beneficie de phototherapie, vitamine K, d’antibiotherapie et de multiples transfusions sanguines. La prise en charge neurochirurgicale a permis un drainage des collections et une hemostase par l’utilisation de cire a os de Horsley et du Surgicel. ABSTRACT Scalp swellings are rather frequent in perinatal medicine, and are usually indicative of birth trauma. This case report describes a newborn with massive bilateral scalp swellings following spontaneous vaginal delivery. This situation led to severe life-threatening anemia and secondary coagulopathy. The baby was managed with phototherapy, vitamin K, antibiotics and multiple blood trans...

The reduction of maternofetal mortality constitute one of the major challenges of developing countries. To reduce this mortality rate, measures have been taken since June 2011 in the northern regions of Cameroon to initiate the strategy of obstetric kits so as to render the cost of childbirth and caesarean sections reasonable. Objectives. The objective of this design study was to evaluate the impact of the utilization of obstetric kits on mother and child health. Methodology. We carried out a descriptive retrospective study in the regional hospitals of Ngaoundere and Garoua going from June 1st 2008 to May 31st 2014. The study interest was mainly concerned by women who gave birth in the given hospitals of Ngaoundere and Garoua. Results. The utilization of obstetric kits increased the rate of childbirth. Birth rate passed from 27.6% to 72.4% .Therefore, there was a link between delivery kits and the number of childbirth. The number of births was greater during the period...

Etude transversale descriptive portant sur les cas de lithiases operes a l’’hopital CMAO de Meskine. Les operes devaient tous etre de nouveaux cas. Les parametres analyses etaient : parametres sociodemographiques, tableau clinique, origine des operes, topographie de lithiases, periode de l’intervention chirurgicale, traitement des lithiases urinaires, composition mineralogique des eaux. Resultats. 46 cas ont ete enregistres du 03 Mars au 18 Juillet 2014, dont 33 hommes et 13 femmes. L’âge des operes allait de 1 a 85 ans pour un âge moyen de 38,6 ans.

Elle pose des problemes d’ordre diagnostique, et therapeutique. Nous rapportons l'observation medicale d'une fillette de 6 semaines, qui presentait des la naissance une masse fronto-nasale molle, expansible aux pleurs de l’enfant, et transilluminable, sans autres malformations associees. L’anomalie s’etait compliquee de meningite suite a une effraction cutanee avec fuite de liquide cephalorachidien. Le diagnostic de meningo-encephalocele etait confirme a la tomodensitometrie cerebrale qui retrouvait egalement une hydrocephalie quadriventriculaire. Le traitement neurochirurgical en un temps avait ete pratique ; les suites operatoires etaient simples.

The Cameroonian government has put in place specialized centers of obstetrical fistula care services whereby the protestant hospital of Ngaoundere since June 2014 is recognized as the reference center for the regions of East and Adamawa (Cameroon). We carried out a cross sectional descriptive study with the objective to evaluate the care of obstetric fistula in this specialized center. 142 women constituted our sample size. Women aged between 26 and 35 years where the most representative of the different age groups. Dystocia delivery was the major cause of these fistula (57% of the cases). Vesicovaginal fistula was the most common type with 79.41%. Low access pathway was used in 93% with fistulorraphy as the major sur...

This was a retrospective study done at the Yaoundé General and Yaoundé Central Hospitals from the 1st of January 1995 to the 1st of January 2005. The inclusion criteria: medical files which had the results of pre and post operatory clinical examinations, neuroradiologic and histopathologic examinations, the post operatory report. The follows up of at least six months. The functional outcome was evaluated using the Karnofsky scale. Of the 62 patients operated for an intraspinal tumor, 12 (19.35%) were selected (nine neurinomas, two neurofibromas, one neurofibrosarcoma). The mean age was 40.66 years +/- 13.20 with a sex ratio of 0.71. The average duration of symptoms before the diagnosis was 17.83 months +/- 5.81; the most frequent symptom was radicular pain (six cases). Five patients were paraplegic...
