ABSTRACT
Background: Congenital cataracts present very important ophthalmological and socio economic problem. It is one of the causes of blindness continuous to receive emphasis as a school health problem throughout the world. Aim: Clinical evaluation and visual outcome following surgery in congenital cataract. Materials and methods: It was a clinical study on the patients who have attended out-patient department of Ophthalmology for a period for a period of 2 year. 50 cases under the age of 12 years who were operated by SICS with PCIOL (PMMA) and Phaco with foldable IOLs were included in study. All the cases were followed for a period of 3 months. Results: Among the 50 cases, positive family history of congenital cataract was present in 6%. Systemic and ocular abnormalities were present in 3 (6%) and 10 (20%) cases of congenital cataract. Majority of children presented with visual acuity of PL. Majority of children got vision between 6/36 to 6/24. 48% presented with total cataract followed by lamellar cataract 36%. Most of the children had amblyopia followed by squint and optic atrophy. Most of the intra operative complications were posterior capsular rupture followed by premature rupture, hyphema and iridodialysis. Posterior capsular opacification was common followed by iritis, shallow AC and corneal edema. IOL implantation was done in 90% of congenital cataract cases and in 5 % of cases secondary IOL is implanted. Mean IOL power calculated was + 18.00D. Conclusion: Early diagnosis and meticulous management of congenital cataract may give satisfactory vision with minimal complications.
ABSTRACT
Background: The objective was to study the prevalence of human leukocyte antigen (HLA)-A*3101 allele among epileptic patients and to assess the safety and effi cacy of antiepileptic therapy. Methods: 295 subjects were selected and divided into two groups, Group I had 192 epileptic patients and Group II had 103 normal healthy controls. After written informed consent, 30 ml of mouthwash sample was collected from each subject and DNA was extracted by standard salting-out technique and used for HLA-A*3101 genotyping by two-step nested allele-specifi c polymerase chain reaction amplifi cation and agarose gel electrophoresis. Results: In Group I, 12 (6.25%) of the 192 patients were tested positive for HLA-A*3101 allele and all were taking carbamazepine (CBZ). Among them, 56 (30%) subjects had developed less severe adverse effects such as headache and giddiness, skin rashes and memory disturbances, and HLA-A*3101 was present in 8 of them while 136 had no adverse effects in which 4 of them were tested positive for the allele. In Group II, 3 (2.9%) of the 103 healthy controls were tested positive for the allele. No difference was found in response to antiepileptic therapy between allele positive and negative patients. Conclusion: The present study had shown that HLA-A*3101 is prevalent in 6.25% of the Indian epileptic population under study. The presence of this allele has a signifi cant association with the development of mild cutaneous reactions like skin rashes. However, no difference was observed in allele positive patients in response to antiepileptic therapy in comparison with allele negative patients.
ABSTRACT
Thirty seven patients with Guillain Barre syndrome were studied. The most common electrophysiologic abnormalities were delayed or absent Median nerve F wave (93.3%), increase in posterior tibial nerve distal latency (91.9%) and delayed or absent posterior tibial nerve F waves (83.9%). Slowing of nerve conduction was associated with the F wave abnormality and distal latency prolongation in most cases. There was no definite relationship between the results of electrophysiological studies and the clinical grade. 15 patients were treated with steroids, 10 with plasmapheresis, 8 with both steroids and plasmapheresis and 3 with immunoglobulins. There was a greater degree of improvement in patients treated with plasmapheresis.
