Renal colic patient; comparison of un-enhanced helical computed tomography, intravenous urography and ultrasound + Plain X-Ray"

To compare Un-enhanced Helical Computed Tomography [UHCT], Ultrasonography [US] + Plain X-Ray and Intravenous Urography [IVU] in the evaluation of patients with suspected renal colic. In 70 patients with renal colic US, plain X-ray, IVU and UHCT were performed to demonstrate urinary stones and other relevant pathologies. Patients were then followed-up to stone passage or removal, and the course of clinical symptoms were noted. 57 patients had ureteral stones based on stone passage or removal. 13 patients did not have ureteral stones based on failure to recover a stone, disappearance of symptoms, and diagnosis unrelated to stone disease. Un-enhanced helical computed tomography was found to be the most useful method in the demonstration of ureteral stones with a sensitivity of 97%. Reformatted images clearly depicted the intraureteral location of stones in most cases. Spiral UHCT showed renal calculi in 15 patients, USG + KUB in 12 and IVU in 9 patients. Non-contrast axial and reformatted spiral CT [UHCT] images were found superior to USG + KUB and IVU in the depiction of ureteral and renal calculi. Reformatted images offer a good alternative to IVU in problematic cases

Ileo-colic intussusception; is hydrostatic reduction worth considering till late?

To evaluate the success rate of hydrostatic reduction of intussusception and incidence of complications in late presenting cases. Prospective study. Study was carried out in Armed Forces Institute of Radiology and Imaging Rawalpindi and different Combine Military Hospitals during last 5 years. All the children up to 2 years age with diagnosis of ileo-colic intussusception and 3 days or less history of onset of symptoms were included in the study. Patients with signs of perforation, suspicion of lead point or long intussusceptum protruding through rectum were excluded. After plain film evaluation, thin barium was instilled through Foleys catheter under fluoroscopic guidance. Rule of 3 was followed and reduction was considered successful when contrast refluxed into terminal ileal segment. Follow up plain x-ray and ultrasound was done after 48 hours to rule out recurrence. Hydrostatic reduction was successful in 18 out of 21 patients collected during last five years. Reduction was incomplete in one case while perforation was observed in 2 cases. These complications were observed in the largest group [52%] of patients reporting on 3rd day of onset of symptoms. A significant number [38%] of patients reached the hospital within 48 hours. Only 2 [10%] patients presented in first 24 hrs but uneventful reduction was possible in later two groups. Careful hydrostatic reduction in cases of ileo-colic intussusception reporting within 72 hrs will reduce hospital stay and patient morbidity in most of the cases

Bone marrow infection with Mycobacterium fortuitum in a diabetic patient

Incidence and prevalence of Mycobacterium fortuitum infection vary greatly by location and death is very rare except in disseminated disease in immunocompromised individuals. We present what we believe is the first case of bone marrow infection with Mycobacterium fortuitum in an HIV negative patient. Bone marrow examination revealed presence of numerous acid fast bacilli which were confirmed as Mycobacterium fortuitum on culture and by molecular analysis. Patient was managed successfully with amikacin and ciprofloxacin

Diagnostic accuracy of computed tomography in brain tumours

This study was conducted at PNS Shifa Naval Hospital Karachi over a period of four years from December 1995 to December 1999. A total of 100 patients were included who underwent computed tomography [CT] scan for suspected brain tumours. Selection criteria included those single intracranial masses labeled as brain tumour on the basis of their CT features. Multiple lesions were excluded. The patients' age ranged from 13-85 years, mean age 43 years with male to female ratio 2:1 The common clinical presentations were headache, diplopia, seizures, personality changes, vertigo, vomiting and progressive neurological deficit. The results of our study revealed that out of hundred cases gliomas were 48, meningiomas 25, pituitary adenomas 12, craniopharyangiomas 6, pineal region tumours 4, acoustic neuromas 3 and choroid plexus papilloma 2. The aim was to first identify, recognize and locate the tumour precisely and then to see its effects on surrounding structures. The objective was to determine the preoperative diagnostic accuracy of CT in brain tumours and compare it with post- operative histopathology results. The diagnostic accuracy of CT scan was found to be 83% on average, when correlated with histopathology
