Analysis of Helicobacter pylori gastritis according to Sydney classification.
No full textIntroduction: Since H. Pylori has been isolated in stomach and duodenum, there were individual methodologies to explain the grading according to colonization and density of microorganism. In 1990 Sydney system of classification was proposed at the 9th world congress of gastroenterology in Sydney Australia, based on topo-graphical, morphological and etiological findings. This classification revised in 1994 and updated by experts in Houston Texas. H. Pylori is major cause of chronic gastri-tis results in gastric and peptic ulcer. It also causes MALT lymphoma and malignan-cy. For histopathological examination four specimens, two from antrum and two from corpus are recommended.Objective: To evaluate the Sydney system of classification and grading for H. Pylori in local population.Methodology: 287 cases of biopsies received at the department of pathology Mu-hammad Medical College, Mirpurkhas Sindh Pakistan, during the period of January 2017 to December 2018 were revised. Sections stained with Hematoxylin and Eosin; Alcian blue and periodic acid Schiff to define H. Pylori and associated pathological changes. The microscopical findings classified according to upgraded Sydney pattern.Results: Out of 287 cases of gastric biopsies 23 (8.0%) were positive for H. Pylori. chronic inflammation present in 168 (58.5%). Neutrophilic activity found in 58 (18.1%). Atrophy without metaplasia observed in 31 (10.8%). Intestinal metaplasia present in 1 (0.3%) cases.Conclusion: Sydney system of grading is best to evaluate chronic gastritis and relia-ble indicator of H. Pylori microorganism.

Therapeutic efficacy of Dornier MPL 9000 for prevesical calculi as judged by efficiency quotient
No full textPurpose: To study the efficacy and safety of the Dornier MPL 9000 lithotripter in the treatment of prevesical calculi using real-time ultrasound monitoring and to see if efficacy is adequately judged by the efficiency quotient (EQ). Patients and Methods: Seventy-six patients underwent ultrasound-guided extracorporeal shockwave lithotripsy (SWL) for prevesical calculi over a period of 43 months. Their age ranged from 8 to 68 (mean 37.6) years, and the male:female ratio was 2.6:1. The size of the stones, measured in two dimensions, ranged from 4 to 25 mm (mean 9.3 mm) and 2 to 15 mm (mean 6.0 mm). No general or regional anesthesia or ureteral stents were used, and all patients were treated in the prone position. The EQ was calculated using the formula: Stone free (%) x 100/(100 + retreatment rate (%) + auxiliary procedures (%).Results: Seventy patients were stone free in a mean time of 15 +/- 14.11 days. The average number of shockwaves used was 2,831 +/- 1,612, and the average number of sessions per patient was 1.7. About 92% of the patients were rendered stone free using in situ SWL alone. No major complication was encountered, and none of the patients required an inpatient stay after SWL. The EQ was 65. Five patients with failed SWL subsequently were rendered stone free, four with salvage ureteroscopy and pneumatic lithotripsy and one with cystolitholapaxy for a symptomatic fragment in the bladder. One patient was lost to follow-up.Conclusion: In situ SWL is a safe and effective treatment for prevesical calculi. It should be used as a first-line treatment for most such stones. Efficiency can be assessed objectively by the EQ
Acute urinary retention: A primary manifestation of chronic lymphocytic leukemia and organ confined prostate cancer
No full textClinical impact of incidental diagnosis of disease on non-contrast-enhanced helical CT for acute ureteral colic
No full textThe role of un enhanced helical CT (UHCT) in the evaluation of acute flank pain suggestive of urinary tract calculi is increasingly appreciated in the last few years. Recent studies have identified the advantages of UHCT in recognizing alternative findings within or outside the urinary tract. These incidental diagnoses on UHCT alter a patient\u27s management and demonstrate the pivotal role of UHCT in rapidly triaging these patients for appropriate management. Clinical impact of incidental diagnoses is maximal in identifying alternate emergent conditions mimicking reno-ureteric colic and in identifying malignancies at an early stage when they are potentially curable

No full textCandidal infections as a cause of recurrent uretero-ileal anastomotic dehiscence
No full textFungal infections are common in immunocompromised patients. The presentation is often subtle and therefore treatment is delayed. Uretero-ileal anastomotic dehiscence due to candidal infection has never been reported before. This case represents an uncommon but potentially life-threatening complication in reconstructive surgery; that is, anastomotic dehiscence due to a unique etiology
