Abstract
This research has been designed to analyze the risk factors of major eye diseases and the genetic alterations contributing to the manifestation of such disease. For this purpose, data was collected from 256 patients diagnosed by an ophthalmologist by using a specialized questionnaire. Blood samples were collected from 100 patients to perform a genetic investigation of cataracts. Whole genomic DNA was extracted from blood samples via the phenol-chloroform method. The purified DNA was used as the template for the amplification of about 400 bp fragments amplifying exons 1 and 2 of the CRYAA gene. The statistical analysis showed that 68% of individuals were blind due to cataracts. During molecular analysis, nucleotide sequences obtained have resulted in one silent mutation that occured at 20 positions in exon 2. It was replacing A>G which in turn substitutes the Lysine at position 70 for Arginine. It was interpreted by statistical analysis that this mutation did not result in a significant change in the CRYAA gene. In addition, protein analysis showed no significant changes in the structure of normal and mutated genes. At last, it is concluded that environmental risk factors play a major role in the studied diseases as compared to genetic factors. It is recommended to extend the study to a larger population to study all exons of the CRYAA gene as well as develop better estimates of the magnitude of the problems of visual loss and eye diseases in the Pakistani population.

Abstract
Articular cartilage is composed of chondrocytes surrounded by a porous permeable extracellular matrix. It has a limited spontaneous healing capability post-injury which, if left untreated, can result in severe osteochondral disease. Currently, osteochondral (OC) defects are treated by bone marrow stimulation, artificial joint replacement, or transplantation of bone, cartilage, and periosteum, while autologous osteochondral transplantation is also an option; it carries the risk of donor site damage and is limited only to the treatment of small defects. Allografts may be used for larger defects; however, they have the potential to elicit an immune response. A possible alternative solution to treat osteochondral diseases involves the use of stromal/stem cells. Human adipose-derived stromal/stem cells (ASCs) can differentiate into cartilage and bone cells. The ASC can be combined with both natural and synthetic scaffolds to support cell delivery, growth, proliferation, migration, and differentiation. Combinations of both types of scaffolds along with ASCs and/or growth factors have shown promising results for the treatment of OC defects based on in vitro and in vivo experiments. Indeed, these findings have translated to several active clinical trials testing the use of ASC-scaffold composites on human subjects. The current review critically examines the literature describing ASC-scaffold composites as a potential alternative to conventional therapies for OC tissue regeneration.

Abstract
BACKGROUND Limb amputation is reported to be a major but preventable public health problem that is associated with profound economic, social and psychological effects on the patient and family especially in developing countries where prosthetic services are unavailable, inaccessible or unaffordable. AIM The purpose of this study was to determine the patterns of and indications for limb amputations. METHODOLOGY A retrospective study, covering a 4-year period, involving 126 patients who underwent amputation at a teaching hospital was carried out. Data on patients including indication for amputation were obtained from theatre record books and folders and analyzed using SPSS and MS Excel. Data was presented in frequencies and percentages. Chi square tests were used to compare categorical variables and differences were considered significant if p<0.05. RESULTS The mean age of the 126 patients was 60.92(SD19.03) years with a median of 67years. There were 68 females and 58 males giving a female to male ratio of 1.2:1. Lower limb amputations were performed in 114(90.48%) and upper limb amputations in 12(9.52%) patients. The commonest indication for amputation was diabetic foot gangrene accounting for 54(42.86%) patients, followed by peripheral vascular disease 43(34.13%) and trauma 12(9.52%). Twenty-one of the patients who had amputations for indications other than diabetic foot gangrene also had diabetes mellitus. Below knee amputation was the commonest procedure performed (43.65%). One hundred and twenty (95.2%) were unilateral and 116 (92.1% ) were performed in a single-stage procedure. CONCLUSION Most of the amputations in the Cape Coast Teaching Hospital were performed in elderly patients, with a slight preponderance of women over men. Lower limb amputations were far more common than upper limb ones. The commonest indication for amputations was diabetic foot gangrene, with below knee amputation being the commonest type. There is an urgent need for public education on diabetes and its complications and on diabetic foot care. The establishment of a multidisciplinary diabetic foot care clinic is advocated if the incidence of limb amputations is to be reduced in the Cape Coast Teaching Hospital.

Abstract
The use of nebulized Ipratropium bromide, quaternary anticholinergic bronchodilators in combination with beta-agonist for the treatment of acute asthma in adults is controversial. In a view of different recommendation the present study is undertaken in Bangladeshi patients. Combination of inhaled Ipratropium bromide and Salbutamol provides greater bronchodilatation than mono therapy with Salbutamol alone in acute severe asthma. Patients of severe asthma (PEFR <50% of predicted) were enrolled into control group (Salbutamol only) and case (Salbutamol + Ipratropium bromide) group. After measurement of peak expiratory flow, patient received 3 doses of 2.5 mg Salbutamol (n=40) only or 3 doses of both 2.5mg Salbutamol and 500mcg Ipratropium bromide at an interval of 20 minutes (n=40) through a jet nebulizer. Peak flow was reassessed 30 & 60 minutes after treatment. Peak flow at baseline was similar in two groups. Then at 30 minutes after nebulization, the mean±SD percentage increase in peak flow was greater in combination group (60.01±35.01%) than Salbutamol group (44.47±25.03%) with difference of 16% (p=0.025). At 60 minutes the percentage increase in peak flow was about 32% greater in combination group than Salbutamol group (94.44±33.70% vs. 62.57±29.26%, p=0.000) and combination group reached percentage predicted peak flow more than 60% while Sabutamol group did not. Ipratropium Bromide and Salbutamol nebulized combinedly have better bronchodilating effect than Salbultamol alone in acute severe asthma.

Abstract
e17054 Background: Cancer is a rising health problem worldwide, Nigeria inclusive. A variety of different tumour types may arise at a host of sites within the head and neck region. This 10-year review is to assess the various sites of primary lesion, gender and age distribution and histopathological types, so as to update data with an earlier study done in our centre between 1997–2001. Methods: This 10 year review of patients with head and neck cancers was carried out at the University of Ilorin teaching, Ilorin, North central Nigeria between January 1997 and December 2006.The hospital is one of 2 teaching hospitals in the zone of 6 constituent states out of 36 states in Nigeria, with an average population of 5 to 6 million (2003 Nigerian census). Information extracted from the case notes of patients with histological results included: Age, sex, clinical features, site of tumour, and the histological types of tumour. The International classification of disease oncology (ICDO) ninth version was used to categorize the sites of the tumour. Results: A total of 138 cases of head and cancers were seen over the 10 year period with an average occurrence of 14 cases/year, male/ female ratio of 1.1 to 1.0, age range of 1.5 years to 85 years with a mean age of 45.23 years, the peak age incidence of fifth to sixth decades of life being 47.2%.The commonest histological type was carcinoma (78.3%), then lymphomas (12.3%), blastomas (5.1%), sarcomas (4.3%). The commonest site were the nose, paranasal sinuses and ears (23.9%), eye (15.2%), nasopharynx (13%), neck (13% -metastatic unknown primary 4.3%), thyroid (12.3%), larynx (10.2%), oral cavity and oropharynx (6.5%), salivary glands (3.6%), mandible (1.4%), and skin (0.74%). Conclusions: This result shows that head and neck cancers occur among Nigerians with no sex differentiation in their prime of life, the histological types are similar to the previous series, however the site seems to have changed with the nose and paranasal sinuses, eye, and nasopharynx being the commonest sites. The metastatic unknown primaries in the neck are much lower. The devastating effects on the individual, family and the community are enormous in a setting with late presentations at the hospital and a strong belief in traditional medicine. Emphasis on prevention of these cancers is stressed. No significant financial relationships to disclose.
