Spinal tuberculosis: a 15 year review at OAUTHC Ile-Ife

A review of the hospital records over 15 years was made. The objective of the study was to describe the clinical presentation, management and outcome of spinal tuberculosis. Thirty-four patients were studied. There were 15(44.16%) males and 19 (55. 9%) females. Their age range was 2-80 years with mean (+/- SD) of 25.28 +/- 22.33 years. The occupations most commonly affected are Students (44.1%), Pre-school Children (17.6%) and Traders (14.7%). Back pain (100%), weight loss (47.1%), paraparesis (47.1%), kyphotic spinal deformity (32.4%) and night sweats (29.4%) were common features. Only 26.5% patients had active pulmonary tuberculosis. All the vertebral segments were involved. The Lumbar spine was the most involved vertebral segment in 50% patients. Using the Westergren method the mean (+/- SD) Erythrocyte Sedimentation Rate (ESR) mm/hour at the initial diagnosis was 83.58 +/- 31.11 mm/hour whereas three months after the commencement of antituberculosis chemotherapy it was 30.06 +/- 11.96 mm/hour. All the patients were given multiple antituberculosis drugs therapy and spinal traction. Spinal support was offered when the patients became ambulant. At the end of two years follow-up, 94.1% patients were alive, while 5.9% patients died during the course of treatment due to overwhelming sepsis. Among the patients that were alive, 14.7% still had persistence of their neurological deficit ie. paraparesis. Ten percent of the patients were mobilised on crutches while 5.96% were confined to wheelchair. This study shows that in tuberculosis endemic areas, symptom of back pain especially in the younger age group should be thoroughly investigated as this group constituted the largest affected population.     

The Relationship Between Glycaemic Control and Non-Alcoholic Fatty Liver Disease in Nigerian Type 2 Diabetic Patients

Background

Metabolic risk factors associated with non-alcoholic fatty liver disease (NAFLD) include Type 2 diabetes mellitus (T2DM), obesity and dyslipidaemia. Prevention or management of these risk factors with glycaemic control, weight reduction and low serum lipid levels respectively have been reported to reduce the risk of NAFLD or slow its progression. Since ultrasound (USS) is a safe and reliable method of identifying fatty changes in the liver, this study was done to determine the relationship between glycaemic control and ultrasound diagnosed NAFLD in T2DM.

An assessment of peripheral vascular disease in patients with diabetic foot ulcer

BackgroundPeripheral vascular disease (PVD) is a chronic limb ischaemia caused by atherosclerosis of the peripheral arteries. Diabetes mellitus is a risk factor for this disease. The most common symptom of PVD is muscle pain in the lower limbs on exercise. In diabetes, pain perception may be blunted by the presence of peripheral neuropathy. Therefore, a patient with diabetes and PVD is more likely to present with an ischaemic ulcer or gangrene than a patient without diabetes. The use of ankle-brachial-pressure index (ABI) in the clinic and bedside provide a measure of blood flow to the ankle. This could help early detection, initiate early therapy and may thus reduce the risk of critical limb ischaemia and limb loss.ObjectiveThe purpose of this study is to evaluate the occurrence of peripheral vascular disease using ankle-brachial index in diabetic patients with and without foot ulcers and the risk factors associated with diabetic foot ulcer (DFU).MethodThis prospective study involved all type 2 DM patients with foot ulcer (DFU population) and those without foot ulcers (non-DFU population) seen in our hospital. Their demographic, clinical and laboratory parameters were noted and documented. Measurement of ABI was done using a portable hand held Doppler and ankle pressures < 0.9 is suggestive of PVD.ResultsA total of 74 patients were recruited. Males were 42 (56.8%) and females were 32 (43.2%). The mean age of the patients was 62.89 ± 10.66 years and the duration of diabetes was 7.61 ± 7.57 years. Forty-six (62.2%) presented with foot ulcer while 28 (37.8%) were without foot ulcer. Patients with PVD represented by ABI < 0.9 was DFU 31(76.4%) while in non-DFU it was 10 (13.4%). Multivariant analysis of variables associated with DFU in those with ABI < 0.9 showed correlation with tobacco use r = .235, p = 0.044; duration of diabetes r = ?.427; p = 0.001; and systolic blood pressure r = ?.301; p = 0.009.DiscussionThe occurrence of PVD determined by the absence of >2 pulses by palpation alone and using ABI was 25.7% and 55.4% respectively. This suggests that assessment by palpation is subjective while the use of Doppler is quantitative and more reliable. DFU patients with PVD showed a significant correlation with tobacco use, duration of diabetes and systolic blood pressure but not with dyslipidaemia.ConclusionThis study shows that these patients had risk factors for PVD. The use of hand held Doppler will aid early diagnosis of critical limb at risk of loss and help to prevent and reduce the high rate of limb loss in our patients.     

Chloroquine-resistant Plasmodium falciparum with reduced sensitivity in vitro to mefloquine and quinine in Zaria, northern Nigeria

Thirty-six P. falciparum isolates collected from children with malaria were tested for their susceptibility to chloroquine, mefloquine and quinine in vitro using the WHO microtest system. 37% of the isolates grew in the presence of 1.6 mumol chloroquine 1(-1) blood, indicating resistance. The sensitivity to both mefloquine and quinine was markedly reduced. The inhibitory endpoints for quinine correlated with those for chloroquine and mefloquine, but no such correlation was found between chloroquine and mefloquine.     

Femoral bifurcation with ipsilateral tibia hemimelia: early outcome of ablation and prosthetic fitting

Femoral bifurcation and tibia hemimelia are rare anomalies. Hereby, we present a case report of a 2-year-old boy who first presented in our orthopedic clinic as a 12-day-old neonate, with a grossly deformed right lower limb from a combination of complete tibia hemimelia and ipsilateral femoral bifurcation. Excision of femoral exostosis, knee disarticulation and prosthetic fitting gives satisfactory early outcome.     

Compartmental pressure in adults with tibial fracture

Acute compartment syndrome is associated with tibial fractures and failure to diagnose it leads to grave consequences. This study was conceived with the aim of determining the intra-compartmental pressure in adults with closed tibial fractures and intended to provide early diagnosis of acute compartment syndrome. The Whitesides injection method was used, using hospital-available materials. The intra-compartmental pressure in the anterior and deep posterior compartments of 52 patients with closed tibial fractures was measured at presentation and 4 hourly for 24 h. In three patients, the pressure was very high, and the differential pressure (i.e. the difference between the diastolic blood pressure and the intra-compartmental pressure) was greater than 30 mmHg, which was diagnostic of acute compartment syndrome. They were all treated by fasciotomy. It is concluded that Whitesides method can be used to diagnose acute compartment syndrome. The apparatus is easy to set up, inexpensive and therefore ideal for use in our environment where sophisticated devices of tissue pressure measurement are not available.

Résumé Le syndrome compartimental aigu, ou syndrome de loge, est associé avec les fractures tibiales et labsence de son diagnostic a des conséquences graves. Cette étude a pour but de déterminer la tension intracompartimentale chez ladulte présentant une fracture fermée du tibia pour pouvoir diagnostiquer précocement un syndrome de loge. Les tensions intracompartimentales dans les compartiments antérieurs et postérieurs profonds de 52 malades avec une fracture tibiale fermée ont été mesurées à ladmission puis toutes les quatre heures pendant 24 h. Nous avons utilisé la méthode de Whitesides avec piqûres en utilisant le matériel disponible dans lhôpital. Chez trois malades la pression différentielle (c.-à-d. la différence entre la tension artérielle diastolique et la tension intracompartimentale) était 30 mmHg ce qui diagnostique le syndrome compartimental. Tous ont été traités par fasciotomie tibiale. Nous concluons que cette méthode de Whitesides peut être utilisée pour diagnostiquer le syndrome compartimental. Lappareil est facile à installer et bon marché et il est recommandé dans notre environnement où les appareils sophistiqués ne sont pas disponibles.
