Study Design: Prospective analytical study. Objectives: The aim was to determine the association between mental depression and symptomatic Lumbar Degenerative Disc Disease (LDDD) in patients with no previous background of mental disorder. We also aimed at determining the incidence of mental depressions in patients with LDDD and the effects of the treatment on the mental depression. Methodology: One hundred and sixty patients with no prior history of mental or behavioral disorders who presented with low back pains arising from LDDD and met inclusion criteria were studied. The clinical findings and Depression Screening Test pro-forma were completed for each. The extracted information was analyzed using Statistical Package for Social Science (SPSS) version 24.0. The statistical significance was set at P Results: One hundred and fifty-three patients completed the study, with a male to female ratio of 1:1.5 and the mean age of the patients was 48.5 years. The marital status was 4.4% single, 86.9% married, 3.8% divorce/separate and 5% widow/widower. Their levels of education were: no formal education (10.00%), primary school level (8.10%), secondary level (27.50%) and Tertiary level (54.40%). Conclusions: This study showed the incidence of mental depression in 32% of the patients with LDDD. We also noted a statistically significant relationship between symptomatic LDDD and level of mental depression with significant improvement in the level of depression at 6th month after treatment. Hence, assessment of the patients’ mental health is important in the management of LDDD.

Background: Primary knee Osteoarthritis (OA) is the commonest articular disease in middle age and elderly people. Primary total knee replacement (TKR) is a known world-wide standard and definitive treatment of primary knee OA following failed adequate non-operative management. It is of clinical importance to assess the clinical and functional outcome of TKR to prognosticate the severity of primary knee OA. The new (2011) knee society scoring system (nKSS) is both surgeons and patients’ assessment tool for the treatment outcome of TKR. Study Design: Prospective interventional analytical study. Aim and Objective: The aim of the study was to determine early clinical and functional outcome of primary total knee replacement in patients with primary knee osteoarthritis using nKSS. The objectives were: 1) To determine the pre-operative nKSS and post operative nKSS;2) To determine relationships between pre-operative nKSS and post operative nKSS at 6 weeks, 3, 6, 9 and 12 months;3) To determine the complication rates in patients undergoing primary TKR in the study centre. Methods: A prospective interventional study of 59 patients aged 51 to 70 years who had 67 Total Knee Replacements (TKRs) participated in the study between November 2015 to June 2018 at National Orthopaedics Hospital, Lagos, Nigeria. Patients’ sociodemographic data, pre-operative and post-operative nKSS system were recorded at 6 weeks, 3, 6, 9 and 12 months during follow up. The data were analyzed using Statistical Package for Social Science (SPSS). Results: There were 41 females and 18 males (M:F = 1:2.3). There were total of 67 TKRs with 31 right TKRs, 20 left TKRs and 8 staged bilateral TKRs. The participants’ age ranged from 51 to 70 years with the mean age of 59.5 (±8.5) years. Four patients did not complete the study due to various reasons. The remaining 55 participants completed the study period with progressive improvement of their post-operative nKSS at 6 weeks, 3, 6, 9 and 12 months post-operativel

Lacking in literature is the use of discard coal to produce activated carbon and in its subsequent use in the storage of natural gas. In this study, the characterization and gas storage evaluation of a largely porous activated carbon with large surface area synthesized from discard coal were investigated. Discard coals are waste material generated from coal beneficiation process. In developing the activated carbon, chemical activation route with the use of KOH reagent was applied. The effects of KOH/discard coal weight ratio (1:1, 2.5:1, 4:1), temperature (400-800 ℃) and particle size (0.15-0.25 mm, 0.25-0.5 mm, 0.5-1 mm) on the adsorptive properties of the activated carbon were methodically evaluated and optimized using response surface methodology. The synthesized activated carbon was characterized using BET, SEM/EDS, and XRD. The results showed that for each activation process, the surface area and pore volume of the resulting activated carbon increased with increased temperature and KOH/discard coal weight ratio. The maximum surface area of 1826.41 m2/g, pore volume of 1.252 cm^3/g and pore size of 2.77 nm were obtained at carbonization temperature of 800 ℃ and KOH/discard coal weight ratio of 4:1. Methane and nitrogen adsorption data at high pressure were fitted to Toth isotherm model with a predictive accuracy of about 99%. Adsorption parameters using the Toth model provides useful information in the design of adsorbed natural gas storage system. According to the requirements of adsorbent desired for natural gas storage, it could be stated that the synthesized activated carbon could well be applied for natural gas storage.

Background: Diabetic foot disease is a foot that exhibits any pathology that results directly from diabetic mellitus or any long-term chronic complication of diabetes mellitus. The aim of the study was to determine the risk factors and indications for amputations in diabetics and to correlate these risks with mortality in our environment. Patients and methods: An audit of consecutive patients who were referred and had amputation as a result of diabetic foot diseases in a tertiary institution in Sokoto, northwest Nigeria over a 2-year period was done. Parameters studied using a predetermined protocol included the bio-data, socioeconomic status, vascular status, Meggit-Wagner grading status, indications for amputation and outcome. Results: There were nineteen amputations done in 19 patients with age range of 45 to 75 years and a mean age of 57.94 ±?8.92. There were more females (68%) than males (32%) giving a M:F ratio of 1:2. Forty-one percent of patients were housewives and 89.5% were of middle socioeconomic status. Seventy-three percent of the patients had no formal education while 31.6% has had diabetes for between 6 and 10 years. All the patients had comorbidity and 78.9% were Wagner's grade V. Ascending cellulitis and sepsis (68.4%) was the commonest indication for amputation. Trans femoral amputation was carried out in 47.4% and 21.1% had reamputation. A mortality rate of 15.8% was recorded and 52.6% defaulted from follow-up. There was no correlation between the risk factors and outcome in these patients (p > 0.05). Conclusions: Amputation was commonly done in the female diabetic housewife with no formal education. Educating these patients, improving their socioeconomic status will help them modify behaviours and identify foot at risk and complications.
