Favorable response to aggressive chemotherapy in a patient with primary plasma cell leukemia.

Primary plasma cell leukemia was diagnosed in a previously healthy 58-year-old man. The unusual presentation with concomitant multiple osteolytic lesions and hepatosplenomegaly, the favorable response to aggressive chemotherapy with COAP, and the relatively long survival of 22 months prompted this report. This and several other cases recently reported should encourage an aggressive therapeutic approach to this disease.

Analgesic effect of ceruletide compared with pentazocine in biliary and renal colic: a prospective, controlled, double-blind study.

The analgesic effect of ceruletide in biliary and renal colic was evaluated by a randomized, double-blind study in 82 patients. Ceruletide was compared with pentazocine, a well-established analgetic agent. Rapid and effective analgesia was obtained by intramuscular injection of ceruletide 0.5 micrograms/kg in 56 patients with biliary colic. The analgesic effect of ceruletide compared well with pentazocine 0.5 mg/kg im, and was associated with remarkably fewer side effects. In 26 patients with renal colic, ceruletide was significantly inferior to pentazocine. These data support the recommendation of ceruletide as a first-choice analgetic agent for biliary colic.

Second malignant neoplasms in patients with non Hodgkin's lymphoma.

A retrospective review of the records of 3886 patients with non-Hodgkin's lymphoma registered at the Princess Margaret Hospital between 1970 and 1985 was undertaken to determine the incidence of second malignant tumours. Three thousand and twenty-one patients with a minimum documented follow-up of 6 months from referral were identified for analysis. The overall observed/expected ratio for all cancers in patients with malignant lymphoma was 1, suggesting no increased risk of developing a second malignant neoplasm compared to the general population. When the data were analyzed independently for each tumour site, statistically significant increased risk of developing acute non lymphocytic leukemia (ANLL) (p less than 0.001) and carcinoma of the tongue (p less than 0.05) were found. An increased risk of lung cancer following lymphoma was detected but was not statistically significant. Survival following diagnosis of ANLL and lung cancer was similar and significantly shorter than that following the diagnosis of other second malignancies. The risk of developing a second primary cancer was significantly related to increasing patient age.

Plasma ferritin and type 2 diabetes mellitus: a critical review.

Multiple factors appear to be involved in the pathogenesis of type 2 (non insulin dependent) diabetes mellitus (DM). One of these factors may be iron overload. This critical review summarizes the major studies on the link between type 2 DM, insulin resistance, glycemic control, diabetic complications and hyperferritinemia. Although some studies suggested that plasma ferritin concentration is positively correlated with insulin resistance and with the risk of acquiring type 2 DM, substantial iron overload is not a typical feature of DM. There is no correlation between plasma ferritin level and glycemic control or diabetic microangiopathic complications.

Adverse reactions to prolonged treatment with high doses of carbenicillin and ureidopenicillins.

Charts were reviewed for 63 patients whose chronic pseudomonas osteomyelitis was treated with high doses of extended-spectrum penicillins for prolonged periods. The incidence of untoward drug reactions was significantly higher than expected. Carbenicillin evoked adverse reactions in 22.8% of patients. However, most of these reactions were mild, and a change of drug was required in only 5.7% of cases. No adverse drug reactions were observed with cumulative doses of less than 750 g. In contrast to carbenicillin, the ureidopenicillins were associated with adverse reactions in 67.7% of patients; most reactions were moderate to severe in intensity; a cumulative dose of greater than 250 g produced adverse reactions; and discontinuation or change of therapy was required in 51.6% of cases. The main adverse reactions to both carbenicillin and the ureidopenicillins included rash, drug fever, leukopenia, eosinophilia, thrombocytopenia, and hepatic damage.

Cancer in pregnancy: maternal and fetal implications.

Cancer is the second leading cause of death in women during their reproductive years, and complicates approximately 0.1% of all pregnancies. When cancer occurs during gestation it poses immense pressure on the pregnant patient, her relatives and her physicians. As cancer is diagnosed during gestation, it raises conflicts between optimal maternal therapy and fetal well-being. In this review, the available data are analysed regarding the impact of pregnancy on the course of the disease, and the effects of the malignant process and its treatment on both the mother and her fetus. Here, attention is focused on the most common malignancies associated with pregnancy; cervical and breast cancer, malignant melanoma and lymphoma. In addition, attention is focused on the available data regarding the impact of cytotoxic and radiation treatments on the mother and fetus.

Fine needle aspiration biopsy in patients with diffusely enlarged spleens.

OBJECTIVE: To evaluate the diagnostic value and potential risk of fine needle aspiration biopsy (FNAB) of the spleen in patients with diffuse splenomegaly due to an undetermined cause. STUDY DESIGN: Retrospective evaluation of the medical records and cytologic material from 58 patients on whom FNAB was performed between 1967 and 1993. RESULTS: Sixty-five FNABs were performed on 58 patients. Lymphoproliferative diseases were found in six; in four additional cases, metastatic adenocarcinoma, sarcoidosis, Candida albicans and enterococcal infection were demonstrated. The remaining 55 biopsies either showed normal splenic tissue or were nondiagnostic. No complications were recorded. CONCLUSION: Splenic FNAB may be useful in some patients with diffuse splenomegaly. The diagnostic yield is rather low. The procedure, however, is simple, safe and well tolerated.

Employee exposure to chromium and plasma lipid oxidation.

Exposure to chromium increases free-radical species in the body, which has an adverse biologic effect. In view of evidence that the oxidation of low-density lipoproteins is important in the pathogenesis of atherosclerosis, the authors measured plasma lipid oxidation and antioxidant levels in 11 welders chronically exposed to chromium and compared them with levels in 15 matched controls. Exposure level was determined by urinalysis. Plasma lipid peroxidation and susceptibility to oxidation were determined by measuring generated thiobarbituric acid reactive substance (TBARS) and lipid peroxides. Total plasma antioxidant status and serum paraoxonase activity were also measured. The Kruskal-Wallis test was used to test for statistical significance. There was no significant difference between the groups with regard to lipid peroxidation, plasma lipid susceptibility to oxidation, total plasma antioxidant status, or serum paraoxonase. Three workers with urinary chromium levels over the biologic exposure index limit (> 10.0 microg/g creatinine) had higher plasma lipid peroxidation and lipid susceptibility to oxidation compared with the rest of the study group. The results suggest that welders exposed to chromium have increased plasma lipid oxidation. The small numbers of subjects and those with elevated urinary chromium limit the power of this preliminary study. Further studies of the association of chromium with plasma lipid oxidation are warranted.
