A fatal eosinophilic process in a Laotian refugee.

A 17-year-old Laotian refugee developed an ultimately fatal disease process characterized by formation of an abdominal eosinophilic mass, peripheral eosinophilia, and elevated serum IgE. No parasitic pathogens that could explain her disease were isolated during life or identified at autopsy. Furthermore, the disease was not consistent with previously described neoplastic, inflammatory, or idiopathic diseases. We believe this process represents a unique, aggressive variation of the hypereosinophilic syndrome, and that immunosuppressive therapy may be warranted.

Polyarteritis nodosa in hairy cell leukemia.

A patient with polyarteritis nodosa (PAN) developing after splenectomy and previously diagnosed hairy cell leukemia is presented. This rare association may provide an insight into the nature of PAN.

Modified trocar-cannula system for percutaneous pancreatic abscess drainage.

A trocar-catheter system using a 7.1-F pigtail catheter and a translumbar needle was used successfully in the percutaneous drainage of a pancreatic abscess via an anterior approach. This system provides a) adequate drainage size, b) adequate length for deep-seated abscesses, and c) pigtail-catheter configuration.

The failed transhepatic cholangiogram.

A study of percutaneous transhepatic cholangiograms in 94 consecutive patients revealed that success is largely determined by the number of passes attempted. Two of 43 patients with dilated intrahepatic ducts had unsuccessful cholangiograms, but in these patients only two and three passes were attempted. In the remaining 41 patients fewer than seven passes were required. In patients with nondilated ducts, the success rate bears an almost linear relationship to the number of attempted passes beyond the fourth pass. Since patient tolerance often limits the number of passes, careful technique is important; one such technique is described. In the cholangiogram failures with nondilated ducts, subsequent liver biopsy had a high diagnostic yield.

CT-assisted pelvic and abdominal aspiration biopsies in gynecological malignancy.

Twenty-four CT-directed biopsies were performed in 17 women with proved gynecological malignancy which had been treated previously by surgery, radiotherapy, chemotherapy or a combination of modalities. CT proved superior to ultrasound biopsy in that the presence of gas in the bowel does not hinder imaging and the use of contrast agents to outline bladder and ureters enables identification of pathological masses even in the presence of massive adhesions and anatomical distortion. Even in small lesions, CT can locate the tip of the needle. The technique, difficulties, specimen handling and clinical relevance are discussed.

Barium duodenography as an adjunct to percutaneous transhepatic cholangiography.

Performance of barium duodenography at the end of transhepatic cholangiography improves visualization of the anatomy of the porta hepatis and lower common bile duct. The relationships of C loop, common the bile duct, and ampulla are clearly demonstrated. Without the barium study, the variability of the relationship between the biliary tree and the duodenum may not be appreciated. The technique is described and illustrated by four cases.

Paradoxical embolism in morbidly obese persons.

Three cases of paradoxical embolism are reported in patients with morbid obesity. Early consideration of the possibility of paradoxical embolism allows the appropriate therapy to be instituted without delay. It appears that these patients are at increased risk for both pulmonary emboli and paradoxical emboli. The necessity of early diagnosis in the pathophysiology of paradoxical embolism is discussed.

Doppler ultrasonic screening prior to venography for deep venous thrombosis.

A total of 244 patients were examined using both ultrasonic Doppler technique and conventional venography for deep venous thrombosis. The Doppler examination was 93.8% accurate overall in detecting the condition, with a specificity of 96% and sensitivity of 85.7%. Indications for venography after Doppler evaluation include: (1) a positive or equivocal Doppler examination; and (2) critically ill patients with negative Doppler results where absolute diagnostic accuracy is essential. Had these criteria been followed in this study, 174 normal examinations would have been avoided and only six large vein thrombi (ileofemoral or popliteal) in 244 examinations would have been misdiagnosed.

Gallstone obstruction and perforation of the duodenal bulb.

A case of gallstone ileus is presented in which the stone became impacted in the first part of the duodenum and then caused perforation at the site of impaction. This is only the second published British case of gallstone impaction at this site. Perforation of the duodenum by a gallstone has not previously been recorded. The clinical and radiological features of this case are discussed.
