Serum Prostate-specific Antigen Following Antibiotics in Symptomatic Patients with Lower Urinary Tract Symptoms

Introduction: With the current practice of routine Serum PSA examination, there arises a diagnostic dilemma with regard totheir further evaluation and treatment.Aim: The aim is to study the incidence of cancer (CA) prostate in cases with elevated Serum PSA.Methodology: We studied 50 men aged between 50 and 80 years with elevations in Serum PSA (total PSA) after certainexclusion criteria, these cases are given a course of antibiotics for 6 weeks and repeat Serum PSA levels obtained. In thosewith persistent elevation in Serum PSA above 4 ng/ml, transrectal ultrasound-guided biopsy was done.Results: In our study population, 36.6% of cases with persistent PSA elevation were proven positive for malignancy by biopsy.Conclusion: A fall in Serum PSA following a course of antibiotic therapy does not exclude the presence of a carcinomatouselement in prostates.

Patient Satisfaction With Complete Denture Fabrication Using Two Neutral Zone Impression Materials - An Invivo Study.

The concept of Neutral zone is an important biomechanical consideration in fabrication of complete dentures. There are different methods of recording the Neutral zone. This article compares the levels of patient satisfaction with complete denture fabricated using two neutral zone impression materials.

Testicular abscess caused by salmonella para-typhi

This case is the first report of a bacteriologically proven testicular abscess in a child caused by Salmonella paratyphi 'A' in Pakistan that clinically simulates a testicular tumour. The case also emphasises that a course of 2 weeks antibiotic is sufficient for testicular abscess if complete surgical debridement is done.

Effects of depth of incision on final outcome in Radial Keratotomy

To assess the effect of depth of incision on the final outcome of radial keratotomy for correction of myopia. Sixty-five eyes with preoperative uncorrected myopia between 2.5-6.0D in subjects with a mean age of 29.2 [+7] years underwent radial keratotomy between Sept 1999--July 2002 in department of Ophthalmology, Military Hospital, Rawalpindi. Based on their preoperative depth of incision the eyes were divided into group-A [twenty-five eyes], with an incision depth of 500-530 micro m, and Group-B [forty eyes], with an incision depth of 531-560 micro m. The comparison between the postoperative visual acuity of two groups was made at the end of study after one years' follow up. A total of Sixteen eyes in Group-A [64%] that were within one diopter of emmetropia at first follow-up reverted back to their preoperative myopic state after one year of surgery as compared to only two eyes [5%] in Group-B [p<0.05]. Hyperopic shift occurred in two eyes [8%] in Group-A, as compared to four eyes [10%] of Group-B [p >0.05]. After one year, refraction showed that only 24% cases of Group-A were within 1 diopter of emmetropia as compared to 85% cases in Group-B. Similarly, 40% cases of Group-A were within 2 diopters of emmetropia as compared to 90% cases of Group-B. Glare and variation of vision in the initial four weeks were the most frequently reported complications in both groups. Depth of corneal incision significantly affects the outcome of surgery, if central optical zone is kept the same in cases of low to moderate degrees of myopia
