Retroperitoneal perforation of a pancreatic cyst during endoscopic retrograde pancreatography

A 70‐year‐old man was admitted to Ueno Municipal Hospital, Ueno, Japan, for evaluation of abdominal distension. Computed tomography showed a 1 × 1 cm cyst at the pancreas tail. Endoscopic retrograde pancreatography (ERP) showed a normal pancreatic duct after the first gentle injection and an enhanced cyst at the pancreas tail. Extravasation of the contrast medium occurred from the pancreatic duct to the superior‐dorsal extrapancreas at the same time of the next low‐pressure manual injection. Computed tomography showed extravasation of the contrast medium from the pancreas cyst to the retroperitoneal space after ERP. It was considered that the cyst wall weakness, in addition to slight elevated pancreatic duct pressure, caused the disruption of the cyst wall.     

Infusion of Cryopreserved Autologous Marrow in the Treatment of Acute Leukemia: A Preliminary Report

Autologous marrow was collected from patients with acute leukemiaduring their first remission, and cryopreserved. In relapse,four of the patients were treated with remission-induction chemotherapymore intensive than the previous treatment, followed by infusionof the cryopreserved autologous marrow. Autologous marrow infusioncaused relatively rapid hematological recovery from the bonemarrow depression induced by high-dose chemotherapy. All fourpatients achieved a second complete remission, but with no maintenancetherapy leukemic relapses were observed in three of them. Onepatient survived without leukemic relapse for 19 months, 13months longer than the previous remission period. Another effectof autoinfusion was reduction in blood products required duringthe bone marrow depression. These observations suggest thatcryopreserved autologous marrow may retain its hemopoietic activityand autologous marrow infusion may be effective in providingearly recovery or rescue from bone marrow failure.     

Endoscopic Diagnosis of Early Malignant Lymphoma of the Stomach

Abstract: The findings and results obtained by endoscopies and direct vision biopsies carried out in 13 patients with early primary gastric lymphoma, were compared with those of 8 patients with RLH, 28 with depressed type of early gastric carcinoma, and 10 patients with benign gastric ulcers, to deal with problems inherent to endoscopic diagnosis of early primary gastric lymphoma The first endoscopy attained a correct diagnosis in only 1 patient (7.7%) but in 7 patients (53.8%) with the final endoscopy. Endoscopic features of early gastric lymphoma characteristically yielded a cobblestone appearance and reticulated erosion when they were compared with that of RLH, early carcinoma and benign ulcer. Furthermore, early gastric lymphoma presented ill demarcated margins associated with discoloration of the mucosa more frequently comparing with that of early gastric carcinoma. Also, hemorrhage, lustrous nodules, regulalr and white-coated ulcer were the findings more frequently seen in early gastric lymphoma but redness was less frequent in early gastric carcinoma. Dye endoscopies provided a more detailed appearance of the lesion and margins than conventional endoscopies. In addition, dye endoscopies made visible the lesions that were not visible by conventional endoscopies, in areas repelling dye solution. In this paper, the importance to pay an attention to the endoscopic findings described above and an application of dye endoscopy was emphasized for detection of an early gastric lymphoma.     

CASE REPORT: Insulin - like growth factor II expression in hepatocellular carcinoma with alcoholic liver fibrosis accompanied by hypoglycaemia

This case of hepatocellular carcinoma (HCC) with alcoholic liver fibrosis, which was not associated with hepatitis viruses, was accompanied by hypoglycaemia. The immunoreactive insulin level was low and other hormonal examinations were almost normal. Immunohistochemical studies showed a high level of insulin-like growth factor II (IGF2) peptide in the HCC section and the size heterogeneity of serum IGF2 investigated by western blot revealed a large form at approximately 15 kDa. These results suggest that the HCC with alcoholic liver fibrosis produced IGF2 and that the hypoglycaemia was caused by tumour-associated IGF2.     

Immediate and Delayed Cardiac Herniations after Intrapericardial Pneumonectomy--Report of Two Cases

Two cases of cardiac herniation following intrapericardial lungresections were reported. One was a case of a 29-year-old male with adenocarcinoma ofthe right lower lobe and the other was a 43-year-old male withsquamous cell carcinoma of the right upper lobe of the lung. In the former, cardiac herniation occurred in the recovery room.In the latter, it occurred during the second operation repairingbronchial fistula which appeared 20 days after the previousintrapericardial surgery. The time delay in the second casewas due to the unsuitable quality of prosthesis for the pericardialdefect.     

Transient Manifestation of Antegrade Conduction Over a Kent Bundle After Ventricular Pacing

Postventricular Pacing Preexcitation. Antegrade conduction over a Kent bundle was transiently manifested after the cessation of ventricular overdrive pacing in two patients; otherwise, the heart behaved as if it had a concealed accessory pathway. Conventional electrophysiologic study suggested either a longitudinal dissociation of an accessory pathway or closely located double accessory pathways. The mechanism of the transient manifestation of ventricular preexcitation was discussed. (J Cardiovasc Electrophysiol, Vol. 3, pp. 423–430, October 1992)     

A Preliminary Report on Autologous Bone Marrow Transplantation for the Treatment of Advanced Non-Hodgkin's Lymphoma

Four patients with advanced non-Hodgkin's lymphoma of unfavorablehistology were treated with marrow-lethal doses of cyclophosphamide(CY) and total body irradiation (TB1) followed by the infusionof cryopreserved autologous marrow. All four patients showedengraftment after autologous bone marrow transplantation andachieved complete remission (CR). Three of them, however, developedrelapse in 1.7, 12.9 and 14.5 mo respectively after the transplantation.The other patient has survived in drug-free CR for more than16.6 mo. There was no treatment-related death although therewere some tolerable complications. These data suggest that theCY-TBI regimen may be effective in inducing CR in patients withadvanced non-Hodgkin's disease but it does not contribute topreventing relapse.
