Complementary DNA encoding three catalytic subunits of protein phosphatase 1 (PP1 alpha, PP1 beta, and PP1 gamma) and the insulin-stimulated protein kinase 1 (ISPK-1) was analyzed for variations in the coding regions related to insulin-resistant glycogen synthesis in skeletal muscle of 30 patients with non-insulin-dependent diabetes mellitus (NIDDM). The human ISPK-1 cDNA was cloned from T-cell leukemia and placental cDNA libraries and mapped to the short arm of the human X chromosome. Single-strand conformation polymorphism (SSCP) analysis identified a total of six variations in the coding regions of the PP1 genes: two in PP1 alpha at codons 90 and 255; one in PP1 beta at codon 67; and three in PP1 gamma at codons 11,269, and 273, respectively. All were, however, silent single nucleotide substitutions. SSCP analysis of the ISPK-1 gene identified one silent polymorphism at codon 266 and one amino acid variant at codon 38 (Ile-->Ser). This variant was primarily found in one male NIDDM patient. This subject, however, did not exhibit an impairment of muscle insulin-stimulated glycogen synthase activation. No significant differences were found in mRNA levels in muscle of the four genes between 15 NIDDM patients and 14 healthy subjects. Our findings suggest that 1) genetic abnormalities in the coding regions of PP1 alpha, PP1 beta, PP1 gamma, and ISPK-1 are unlikely to be frequently occurring causes of the reduced insulin-stimulated activation of the glycogen synthesis in muscle from the analyzed group of NIDDM patients; 2) the mRNA levels of PP1 alpha, PP1 beta, PP1 gamma, and ISPK-1 are normal in muscle from the NIDDM patients; and 3) putative inherited defects in insulin-stimulated activation of muscle glycogen synthesis in patients with insulin-resistant NIDDM may be located further upstream of ISPK-1 in the insulin action cascade.

Invasive pulmonary aspergillosis generally occurs in immunocompromised hosts such as patients with leukemia, and other malignancies, who are receiving anti-cancer chemotherapy. In this report, two non-immunocompromised patients who developed invasive pulmonary aspergillosis are presented. Case 1: A 63-year-old man complained of productive cough and fever. He received antibiotic therapy from his personal physician. This symptoms did not respond, however, and dyspnea developed. He was then transferred to our hospital, about one month after the onset. The chest X-ray showed a meniscus shadow suggesting an aspergilloma in the right upper lung field and an infiltrative shadow in the remaining right lung field. Case 2: A 78-year-old man was admitted because of dyspnea, productive cough and appetite loss over the previous three months. The chest X-ray showed a meniscus shadow in the left upper field, an infiltrative shadow in the left lower field and a right pleural effusion sign was also observed. Both cases were diagnosed as having aspergillosis, early in their illness, by the detection of aspergillus antigen in their sera and histopathological and cultural studies of specimens obtained by TBLB. Both improved with intravenous amphotericin B (30 mg/day) and intravenous ulinastatin (200000 IU/day) administration. On the examinations conducted during hospitalization, there was no evidence of any immunosuppressive diseases or immunoincompetent conditions such as leukemia, and other malignancies human immunodeficiency virus infection, diabetes or alcoholism.

The clinicopathologic features of 23 patients with hematophagic histiocytosis (HH) are described. All of them exhibited increased histiocytes associated with hemophagocytosis in the marrow. The patients usually presented with fever, hepatosplenomegaly, lymphadenopathy, and cytopenia. The underlying illnesses were heterogeneous, including non-Hodgkin's lymphoma in 17, systemic lupus erythematosus in one, diabetes mellitus in one, acute myelomonocytic leukemia in one, myelodysplastic syndrome in one, and unknown cause in two. Among 17 non-Hodgkin's lymphoma, 14 were peripheral T-cell lymphoma, two were B-cell lymphoma, and one was an undefined phenotype. Among 14 patients with peripheral T-cell lymphoma, six of the patients had nasal T-cell lymphoma. Five of these 14 patients initially diagnosed as malignant histiocytosis turned out to be T-lineage lymphoma after immunophenotypic studies. Active infections, most of viral origin, were documented in eight patients, including Epstein-Barr virus in three, cytomegalovirus in three, herpes simplex virus in three, Pseudomonas aeruginosa in one, Bacteroides vulgatus in one, and mycoplasma in one. Some of them had mixed virus and bacteria infection. Sixteen (70%) of our patients died of their acute illness within 10 weeks of the diagnosis of HH. In the past, the clinical and histologic differentiation between hematophagic histiocytosis and true histiocytic neoplasm (histiocytic medullary reticulosis/malignant histiocytosis) has proved difficult, but now these can be distinguished with immunohistologic, immunogenetic, and cytogenetic studies, especially in the cases of peripheral T-cell lymphoma with hemophagocytic syndrome.

The addition of 5 years of follow-up and over 411,000 person-years of observation to a cohort of 34,081 men and women employed in U.S. furniture and other related industries allowed the investigation of mortality patterns among women and minority races in addition to white men. A significant excess of pleural mesotheliomas occurred among white men (standardized mortality ratio [SMR] = 3.7, 95% confidence interval [CI] = 1.2-8.7) but could not be linked to a particular type of furniture manufacturing. SMRs for myeloid leukemia and chronic nephritis were elevated among white men employed in the wood furniture industry but were not statistically significant. Males in the black/other race categories in wood furniture plants showed nonsignificant mortality excesses for infectious diseases and cancers of the prostate and colon and rectum. Among white women employed in wood furniture plants, mortality was elevated for cancers of the pancreas and lung during the most recent follow-up period. In metal furniture plants, mortality was raised among men in both race groups for kidney cancer (black/other SMR = 8.0, 95% CI = 1.6-23.2; white SMR = 2.1, 95% CI = 0.4-6.2) and diabetes mellitus (black/other SMR = 2.2, 95% CI = 0.6-5.6; white SMR = 1.8, 95% CI = 0.7-3.9). Stomach cancer mortality was significantly elevated (SMR = 3.3, 95% CI = 1.3-6.8) among white men in metal furniture plants and was of the same magnitude over both the previous and the most recent follow-up periods. Among those working with textiles, SMRs were significantly elevated for leukemia (SMR = 6.1, 95% CI = 1.2-7.8) and cancers of the colon and rectum (SMR = 3.2, 95% CI = 1.3-4.5) for white women. Lung cancer mortality was increased for white men and women in textile operations, but SMRs were not statistically significant. SMRs for a number of other causes of death that were elevated at the end of the earlier follow-up period were not increased during the new follow-up period.

The interleukin-2 receptor (IL-2R) is expressed on proliferating T-lymphocytes following antigen stimulation. Activated IL-2R bearing lymphocytes accumulate as cellular infiltrates in autoimmune thyroiditis, insulin-dependent diabetes mellitus, rheumatoid arthritis and graft rejection. Affected cells in Hodgkin's disease, hairy cell leukaemia, non-Hodgkin's lymphoma, cutaneous T-cell lymphoma and lymphoid blast crises of chronic myeloid leukaemia also express IL-2R. Anti-IL-2R monoclonal antibodies or chimeric IL-2R toxins provide a way of selective elimination of such cells. These have been used in experimental models of autoimmunity and transplantation with beneficial results, providing a novel way of selective immunosuppression. In open uncontrolled trials, chimeric IL-2R toxin was found to be safe and effective in patients with refractory rheumatoid arthritis, insulin-dependent diabetes mellitus and IL-2R bearing leukaemias and lymphomas.

Pancreatic islets of 36 autopsy cases with transfusional iron-overload were examined. Immunohistochemical and histochemical stainings were used to clarify the relationship between blood transfusion and iron deposition in the islet. Disease of the lymphohemopoietic system (leukemia, lymphoma, aplastic anemia) or liver (carcinoma and/or cirrhosis) accounted for 86.1% of the patients' main diagnosis. Sixteen of them had slight hemosiderin deposition (Group 1), twenty cases had severe hemosiderin deposition (Group 2). Another ten cases were used as controls (Group 3). The cases had a similar age distribution to Group 1 and 2, with neither blood transfusion nor hemosiderin deposition. The volume of blood transfusion was 6.1 +/- 3.6, 17.5 +/- 12.2 L for Groups 1 and 2, respectively. The plasma glucose was 137.8 +/- 54.4 and 170.6 +/- 108.4 mg/dL, respectively. Four cases in Group 1 and 14 cases in Group 2 had glycosuria. The number of islet cells with hemosiderin increased with the enlargement of transfusion volume (r = 0.664, P < 0.001). Plasma glucose also related with the percentage of hemosiderin positive islet cell (r = 0.386, P < 0.025). In severely iron-overloaded cases, hemosiderin was selectively deposited in B cells of the islet. It was concluded that large amounts of blood transfusions for non-congenital disease can induce selective hemosiderin deposition and impairment of pancreatic B cell that may result in hyperglycemia and diabetes mellitus of the patients.

This is a report of a 38-yr-old parturient with multiple medical problems including diabetes mellitus, bronchial asthma, chronic myelogenous leukaemia, pre-eclampsia and a recent myocardial infarction. After medical management in the coronary care unit, it was decided to proceed with a Caesarean section. The choice of anaesthetic was made by the patient and had to be modified in accordance with her medical condition. Cardiovascular monitoring included PA catheterisation and transoesophageal echocardiography. A general anaesthetic was performed using fentanyl, thiopentone and succinylcholine. The outcome was satisfactory for both parturient and baby.

The design and construction of a new class of recombinant therapeutic agents, receptor-specific cytotoxins, has occurred within the last 5 years. Development of a number of receptor-targeted fusion toxins has been based on a detailed understanding of the structure-function relationships of both diphtheria toxin and Pseudomonas exotoxin A, and availability of the nucleic acid sequences of each structural gene. A variety of fusion toxins in which the native receptor-binding domain of either diphtheria toxin or Pseudomonas exotoxin A has been genetically replaced with either a polypeptide hormone or growth factor have been constructed. These fusion toxins selectively intoxicate receptor-bearing cells in vitro and are active in a variety of animal model systems. DAB486IL-2, and IL-2 receptor targeted cytotoxin, is the first fusion toxin to be evaluated in patients. Phase I/II clinical trials have been performed in refractory leukemia/lymphoma, severe rheumatoid arthritis, and Type 1 diabetes. DAB486IL-2 has been administered to more than 200 patients, has been well tolerated, and has shown encouraging signs of potential efficacy in all three clinical indications. Thus, DAB486IL-2 represents a new class of targeted biological therapeutic response modifiers whose mode of action is based on selective elimination of target cells.

Eleven cases of rhinocerebral mucormycosis (RM) encountered over a 13-year period were reviewed. Predisposing factors included leukemia (36%), diabetes mellitus (27%), aplastic anemia (9%), myelodysplastic syndrome (9%), and treatment with immunosuppressive medications necessary to maintain solid organ or bone marrow graft viability (64%). Two patients had no predisposing factors. Clinical findings included headache (73%), fever (55%), black nasal eschar (45%), orbitofacial cellulitis (36%), cranial nerve palsy (36%), altered sensorium (36%), and hemiparesis (27%). Seven patients presented with destruction of the paranasal sinuses and local invasion; three with direct extension to the frontal or temporal lobes. Four patients displayed hematogenous dissemination to the cerebrum, brain stem, and cerebellum from a primary pulmonary focus. The seven patients with sinus involvement were treated with aggressive surgical debridement. Two patients with focal intracerebral lesions underwent either open craniotomy or stereotactic biopsy. Amphotericin B was administered intravenously to all patients. Local irrigation via a percutaneous catheter was performed in the seven patients with sinus disease and in one case of intracranial abscess. All seven patients with intracranial infection died, in contrast to four patients that survived with infection localized to the sinuses and orbits. All survivors had been treated with a combination of surgery and amphotericin B therapy. This review demonstrates that RM is increasingly affecting patients with sources of immunosuppression other than diabetes mellitus. Early aggressive therapy to prevent cerebral involvement by this severe infection provides the best chance for a good outcome.

Mucormycosis is an opportunistic fungal infection that commonly begins by invading the respiratory tract. The purpose of the present study was to define the clinical presentation of pulmonary mucormycosis and to evaluate current treatment regimens. Thirty patients treated at our institution and 225 cases reported in the literature were reviewed. For the combined groups, the mean age at presentation was 41 +/- 21 years and associated medical conditions included leukemia or lymphoma (37%), diabetes mellitus (32%), chronic renal failure (18%), history of organ transplantation (7.6%), or a known solid tumor (5.6%). The in-hospital mortality was 65% for patients with isolated pulmonary mucormycosis, 96% for those with disseminated disease, and 80% overall. The mortality in patients treated surgically was 11%, significantly lower than the 68% mortality in those treated medically (p = 0.0004). The most common causes of death were fungal sepsis (42%), respiratory insufficiency (27%), and hemoptysis (13%). Pulmonary mucormycosis has a high mortality; however, antifungal agents appear to improve survival. In addition, surgical resection may provide additional benefit to patients with pulmonary mucormycosis confined to one lung.
