Left Anterior Descending Coronary Artery and Multiple Peripheral Mycotic Aneurysms Due to Mycobacterium Bovis Following Intravesical Bacillus Calmette-Guerin Therapy: A Case Report.

The use of live attenuated intravesicular Bacillus Calmette-Guerin (BCG) therapy is a generally accepted safe and effective method for the treatment of superficial transitional cell carcinoma (TCC) of the bladder. Although rare, < 5% of patient's treated with intravesicular BCG therapy may develop potentially serious complications, including localized infections to the genitourinary tract, mycotic aneurysms and osteomyelitis. We present here a case of a 63-year-old male who developed left coronary and multiple peripheral M. Bovis mycotic aneurysms as a late complication of intravesicular BCG therapy for superficial bladder cancer. The patient initially presented with acute onset pain and swelling in the left knee > 2 years following initial therapy, and initial workup revealed a ruptured saccular aneurysm of the left popliteal artery as well as incidental bilateral common femoral artery aneurysms. Following endovascular treatment and additional workup, the patient was discovered to have additional aneurysms in the right popliteal artery and left anterior descending artery (LAD). Surgical pathology and bacterial cultures obtained from the excised femoral aneurysms and surgical groin wounds were positive for Mycobacterium Bovis, and the patient was initiated on a nine-month antimycobacterial course of isoniazid, rifampin and ethambutol. Including the present case, there has been a total of 32 reported cases of mycotic aneurysms as a complication from intravesicular BCG therapy, which we will review here. The majority of reported cases involve the abdominal aorta; however, this represents the first known reported case of a coronary aneurysm.

Opacification of the genitourinary collecting system during MDCT urography with enhanced CT digital radiography: nonsaline versus saline bolus.

OBJECTIVE: The purpose of this study was to determine whether a saline bolus during CT urography improves urinary collecting system opacification and whether the addition of enhanced CT digital radiography (CTDR) improves urinary collecting system visualization with or without a saline bolus. MATERIALS AND METHODS: One hundred eight CT urography and enhanced CTDR examinations were reviewed. Fifty-four patients were given a saline bolus during CT urography, and 54 patients underwent CT urography without a saline bolus. Urinary collecting system opacification was evaluated by group (saline vs nonsaline), imaging technique (CT urography alone vs CT urography plus enhanced CTDR), number of enhanced CTDR images, and site of nonopacified urinary segments. Using a multivariate logistic regression model, we determined significance of variables and odds of complete opacification. RESULTS: In the saline group, 248 nonopacified sites were identified on CT urography alone and 95 sites with CT urography plus enhanced CTDR. In the nonsaline group, 185 nonopacified sites were identified on CT urography alone and 59 sites with CT urography plus enhanced CTDR. Combining both groups, 433 nonopacified sites were identified with CT urography alone and 154 sites with CT urography plus enhanced CTDR. Multivariate logistic regression showed significance for group (p = 0.010), imaging method (p < 0.0001), number of enhanced CTDR images (p = 0.048), and site of segment opacification (p < 0.0001). The renal pelvis shows the greatest odds and the distal ureter the lowest odds for complete opacification by group or imaging method. CONCLUSION: The addition of a saline bolus offers no improvement, whereas the addition of enhanced CTDR offers significant improvement in collecting system opacification during CT urography.

Lipoma primario de hígado / Primary lipoma of the liver

Se informa un caso de lipoma primario del hígado en una mujer de 57 años con historia de diabetes mellitus no insulinodependiente y tres días con dolor abdominal, distensión, náusea y vómito. A la exploración física se encontró hígado palpable 5 cm por debajo del margen costal derecho sin esplenomegalia ni ascitis. La tomografía computada reveló un tumor bien delimitado con atenuación de grasa y la RM demostró lesión bien circunscrita con intensidad de señal brillante. Se realizó lobectomía hepática derecha. El espécimen resecado midió 28.6 x 18.3 x 8.2 cm y pesó 2,200 g. El tumor de color amarillo y bien circunscrito midió 15 x 9.5 cm, estaba constituido por células adiposas maduras que empujaban al tejido hepático en la periferia. La paciente se encontraba asintomática seis meses después de la cirugía.

Pain relief in chronic pancreatitis by pancreatico-jejunostomy. An institutional experience

Effective pain control in chronic pancreatitis can be accomplished by pancreatic resection or decompression. Pancreatico-jejunostomy (PJ) has been reported to be effective for relieving pain in 70-80 perecnet, of cases. The present study analyses the authors's long term results with PJ in the treatment of pancreatic pain. From 1963 to 1993, 49 patients with chronic pancreatitis underwent PJ for uncotrollable pain. General and radiologic characteristics, intraoperative findings and outcome were ana-lyzed. Mean age was 35 ñ 13 years, 34 were male and 15 female. Alcoholic etiology was documented in 23 patients. Multiple pancreatic calcifications were found in 33 patients. Pancreatic biopsy confirmed chronica pancreatitis in all patients. There was one operative mortality, 12 minor, and 4 major complications. In a mean follow-up of 6.5 years, 98 perecent of the total group was found to be free of pain. Pancreatic function remained stable in most patients. PJ is an excellent procedure for pain control that allows stable pancreatic function
