Serum IgE levels in patients with cancer.

Serum levels of IgE and carcinoembryonic antigen (CEA) were determined in 100 patients with carcinoma of the breast and 81 with colon carcinoma in different stages of their disease. CEA levels reflected the stage of the disease and increased progressively from stage 1 to 4. In contrast, all patients regardless of their type of malignancy, stage of the disease, or CEA level had a similar IgE blood level which did not differ from that of the control group.

Quinidine-induced vasculitis.

Four patients developed nonthrombocytopenic purpura two to three weeks after initiation of quinidine therapy. The skin lesions disappeared and did not recur after cessation of quinidine therapy. Histologic examination revealed leukocytoclastic vasculitis with deposition of C3, IgA, and/or IgM in the small dermal vessels. Since quinidine purpura is usually associated with thrombocytopenia, the possibility of leukocytoclastic vasculitis as an additional cause of purpura is stressed.

Cotrimoxazole reaction simulating sepsis.

A patient is described who developed fever, chills and leucocytosis on two occasions following the administration of cotrimoxazole. This rare reaction simulating sepsis in patients treated with cotrimoxazole is of clinical importance.

Immunoglobulin E response during measles.

Serum IgE levels were determined in 41 patients with measles infection. 23 patients (56%) had an increased level (greater than 20%) during the acute phase of the disease in comparison with the recovery phase. 14 showed no change, and decreased levels were observed in 4 patients only. In contrast, both IgG and IgA levels decreased or remained unchanged in the majority of the patients during disease activity. The changes in the pattern of serum immunoglobulins during measles might be attributed to selective depletion of T-cell subpopulations.

Ocular changes in invasive osteogenic sarcoma of the skull.

Serial narrow-band green-light fundus photographs documented the evolution of descending optic atrophy in a case of rapid bilateral blindness produced by a highly invasive osteogenic sarcoma of the base of the skull. Disappearance of the nerve fiber layer (NFL) was observed to take place between the sixth and 12th week after onset of blindness; thus, it is similar to the evolution of descending atrophy found to occur in clinical cases of blindness caused by traumatic involvement of the optic nerve. Parallel to the disappearance of the NFL there was an increase in optic nerve head excavation and a change in the appearance of the vessels on the disk surfaces.

Carcinoma of lung with a solitary cerebral metastasis. Surgical management and review of the literature.

During the years 1975 to 1980, 10 male patients and 1 female, with ages ranging between 40 to 61 years, underwent combined resection of primary lung cancer and solitary brain metastasis. In 8 patients the lung cancer was diagnosed and treated first. In those patients, craniotomy for removal of a solitary brain metastasis was carried out 8 to 60 months (mean, 27 months) after excision of the lung tumor. In 3 patients, brain metastasis was diagnosed and treated first and lung excision followed, 2 to 4 weeks after craniotomy. The most common histologic type of the tumor was adenocarcinoma (63.6%). There were no operative deaths. Three patients survived less than 6 months after surgery and were considered as a failure of surgical treatment. Seven patients lived longer than 1 year and three of them are still alive with a follow-up period between 2 to 3 1/2 years after both operations. One of the patients underwent recently successfully second brain intervention for removal of recurrent histologically identical solitary brain metastasis and is well. Our results and those reported in literature encourage the combined surgical removal of primary lung cancer and a solitary brain metastasis.

Survival after sudden obstruction of the left main coronary artery.

Left main coronary artery (LMCA) stenosis occurs in 10% of patients undergoing coronary arteriography, but total occlusion is rare. Goldberg et al reported 6 cases of complete obstruction of the LMCA among 2,200 patients studied arteriographically. Sudden obstruction of the LMCA should be lethal, and we found no report describing survival with sudden obstruction of the LMCA. The present report describes such a patient.

Use of hydrogen gas clearance for measurement of renal circulation. An experimental study.

Inhalation of hydrogen gas and its immediate diffusion into the blood permits an accurate and reproducible determination of its clearance through a fine platinum electrode inserted in the renal cortex. The oxidation of molecular hydrogen at the surface of the electrode generates a current which is then easily recorded. Such recordings accurately reflect regional arterial circulation. Experiments have been done in rats to determine regional renal cortical arterial circulation in (1) normal conditions, (2) immediately following unilateral, complete ureteral obstruction, and (3) following a twenty-four-hour ureteral obstruction. Hundreds of simple and reproducible recordings were obtained. Although acute obstruction does not immediately affect cortical blood supply, a twenty-four-hour obstruction was accompanied by a 31.3 per cent reduction in circulation.

The relative value of skin tests and radioallergosorbent test in the diagnosis of bee sting hypersensitivity.

The relative diagnostic value of ST and RAST was evaluated in 97 patients with BSH. Eighteen patients had LRs, 79 showed SRs including 18 with urticaria, 26 had bronchospasm, and 35 had anaphylactic shock. ST but not the RAST reactivity was strongly related to the severity of the clinical reaction (p less than or equal to 0.001) and found superior to the RAST in identifying patients with SRs in whom venom therapy was indicated.

Posttransfusion non-A, non-B hepatitis after cardiac surgery: a prospective study.

In a prospective study of 50 recipients of HBsAg-negative blood who had undergone cardiac surgery, 4 (8%) developed acute non-A, non-B hepatitis. The patients who developed hepatitis had received significantly more units of blood or blood products than the patients who had no hepatitis. The incubation period of the disease was 4-13 weeks, 3 patients were asymptomatic with peak alaminotransferase (ALT) levels of 320-497 U/1 and 1 patient was jaundiced with a peak ALT of 3,400 U/1. 1 of the patients had high ALT levels after 21 weeks of observation, while 3 patients recovered after 7-10 weeks. It is concluded that non-A, non-B posttransfusion hepatitis in Israel is a medical problem similar to that in the USA and that the clinical picture of the disease varies from a mild asymptomatic to a symptomatic and protracted course.
