An outbreak of metal fume fever (MFF) among workers involved in cutting brass pipes with electric cutting torches in an enclosed, poorly ventilated steam condenser is described. Twenty-six workers were affected. Symptoms most commonly reported were fever (21), dyspnea (23), chills (21), headache (21), and nausea (19). Fourteen of the workers experienced the symptom of an unusual sweet or metallic taste in the mouth. Clinical signs were limited to wheezing or rales in eight patients. Leukocytosis and an increase in band cell forms were noted in 21 and 20 of 24 workers, respectively. The median time interval between exposure and onset of symptoms was five hours. None of three workers who spent less than one hour in the condenser became ill, whereas 25 of 26 of those who spent more than one hour became ill (p = .001). Five of 12 workers had urine copper levels in excess of 0.05 mg/l. To our knowledge, this is the first reported outbreak of MFF for which urinary copper levels have been measured.

A 27-year old woman admitted to the hospital after 5 days of vaginal bleeding at 12 weeks gestation had had a copper-T IUD inserted 10 months previously. The IUD string was no longer visible at pregnancy testing. Prior to admission she had experienced lower abdominal pain, increasingly heavy vaginal bleeding, fever, malaise, chills, and vomiting. Intravenous ampicillin and metronidazole were commenced and the uterus was evacuated under a general anesthetic. The copper-T was removed from the uterine cavity. A uterine swab at operation and preoperative blood cultures grew E. coli. A moderate degree of disseminated intravascular coagulation (DIC) was indicated by a coagulation profile. The case demonstrates that the copper-T may be associated with intrauterine sepsis and DIC. In the 1st trimester the risk of abortion following removal of a device is near 30%, while the rate of abortion for women in whom the string is no longer visible is near 48%. Patients presenting with pregnancy in the presence of an IUD and symptoms of sepsis should have the uterus evacuated under suitable antibiotic cover.

A 48-year-old man who had been a welder for 25 years was admitted to our hospital on February 18, 1990 for investigation of a diffuse bilateral lung shadow that had a ground-glass appearance. On the day of admission, he had been welding copper water supply pipe and used silver brazing with an oxyacetylene torch. After almost 7 hours of work, he had a chill, high fever, and dyspnea. Blood gas analysis revealed severe hypoxemia (PaO2 34.5 Torr, PaCO2 29.4 Torr). The level of copper in serum was slightly higher than normal (174 micrograms/dl). A transbronchial lung biopsy specimen showed lymphocyte infiltration and fibrous changes of the alveolar walls, which seemed to be granulomatous pneumonitis. Steroid therapy was effective against the symptoms, and the radiographic findings also improved. We think this is a rare case of interstitial pneumonitis caused by inhalation of cadmium fumes contained in silver brazing.

Lymphomas are the fifth most common malignancy in the United States and are increasing in incidence. Despite being among the most responsive malignancies to radiation and chemotherapy, the majority of patients relapse or have progressive disease. Monoclonal antibodies (MAbs) directed at cell-specific surface antigens have been useful in the diagnosis of lymphomas and, more recently, the therapeutic mouse-human chimeric MAb rituximab has demonstrated effectiveness in B cell lymphomas. Conjugating MAbs to radionuclides is a strategy for improving the efficacy of MAb lymphoma therapy by delivering radiation in close proximity to the tumour (radioimmunotherapy or RIT). In addition, the low dose rate of the delivered radiation may exert a greater antitumour activity than an equivalent dose of conventional external beam radiation. The antigenic targets for MAb therapy have included CD20, CD22, HLA-DR, and B cell idiotype. Radionuclides that have been used include iodine-131, yttrium-90, and copper-67; there are relative merits and disadvantages to each source of radiation. Clinical studies to date have focused on relapsed and refractory patients with both indolent and aggressive lymphomas, although more recent studies have included previously untreated patients with indolent lymphoma. Radioimmunoconjugate has been delivered as either single or multiple doses. Response rates have varied widely, dependent on the patient population and the response criteria. Of note, complete responses can be achieved in this typically refractory patient group. Toxicities have generally consisted of mild infusion-related nausea, fever, chills, and asthenia. Neutropenia and thrombocytopenia are the dose-limiting toxicities and have prompted the incorporation of autologous stem cell support as a means of achieving dose escalation. To date, RIT has been delivered to highly selected patients in relatively few centres with requisite equipment and specialised personnel. In addition to these requirements, cost is likely to be a barrier to widespread use. The combination of RIT with chemotherapy at conventional or high dose, or with biological agents is a fertile area for investigation. The potential of RIT in the treatment for lymphomas will be defined only by well designed comparative prospective clinical studies.

A.H. Robins, makers of the Dalkon Shield, recently issued a letter to doctors suggesting that the problems of Actinomyces infection and colonization associated with long-term use of IUDs can be minimized by replacing inert IUDs at periodic intervals, generally not exceeding three years. However, David Eschenbach of the University of Washington believes that there are no final answers yet as to the prevention and management of this serious though rare disease, and recommendations are really just opinions. Actinomyces israelli is the species most commonly associated with pelvic colonization or infection; it is commonly a commensal organism of the oropharynx and the bowel, but not the genital tract. Symptoms that warn of infection of the genital tract include abdominal pain; nocturnal chills or sweats; vaginal discharge; intermenstrual bleeding; and increased menstrual bleeding. Infection can be fairly mild and resolved with IUD removal, or it can produce tubal abcesses, generally unilateral, which can be fatal, as in a young woman who developed massive pelvic abscess which later spilled 1500 cc of free pus into the abdominal cavity. Plastic inert IUDs are associated with a greater prevalence of Actinomyces infection than are copper-bearing IUDs. Pap smear can detect the presence of Actinomyces organisms, which are seen as branching filaments, sulfa granules or irregular islands of amorphous material which stain blue to brown or black. The organism may either be pathogenic or commensal, depending on the presence of leukocytes. Overall prevalence of Actinomyces showing up on Pap smears of IUD users is estimated at 80% to 90% of IUD users. Treatment suggestions depend on whether the patient has symptoms or is asymptomatic, and whether the presence of the organism represents an infection or a colonization. IUD removal, antibiotic treatment, and if necessary, surgical excision are recommended. Monitoring programs for IUD users are briefly discussed.

Unlike Escherichia coli, the cyanobacterium Synechocystis sp. strain PCC 6803 is insensitive to chill (5 degrees C) in the dark but rapidly losses viability when exposed to chill in the light (100 micromol photons m(-2) s(-1)). Preconditioning at a low temperature (15 degrees C) greatly enhances the chill-light tolerance of Synechocystis sp. strain PCC 6803. This phenomenon is called acquired chill-light tolerance (ACLT). Preconditioned wild-type cells maintained a substantially higher level of alpha-tocopherol after exposure to chill-light stress. Mutants unable to synthesize alpha-tocopherol, such as slr1736, slr1737, slr0089, and slr0090 mutants, almost completely lost ACLT. When exposed to chill without light, these mutants showed no or a slight difference from the wild type. When complemented, the slr0089 mutant regained its ACLT. Copper-regulated expression of slr0090 from P(petE) controlled the level of alpha-tocopherol and ACLT. We conclude that alpha-tocopherol is essential for ACLT of Synechocystis sp. strain PCC 6803. The role of alpha-tocopherol in ACLT may be based largely on a nonantioxidant activity that is not possessed by other tocopherols or pathway intermediates.

Cell water permeability and cell wall properties are critical to survival of plant cells during freezing, however the underlying molecular mechanisms remain elusive. Here, we report that a specifically cold-induced nuclear protein, Tolerant to Chilling and Freezing 1 (TCF1), interacts with histones H3 and H4 and associates with chromatin containing a target gene, blue-copper-binding protein (BCB), encoding a glycosylphosphatidylinositol-anchored protein that regulates lignin biosynthesis. Loss of TCF1 function leads to reduced BCB transcription through affecting H3K4me2 and H3K27me3 levels within the BCB gene, resulting in reduced lignin content and enhanced freezing tolerance. Furthermore, plants with knocked-down BCB expression (amiRNA-BCB) under cold acclimation had reduced lignin accumulation and increased freezing tolerance. The pal1pal2 double mutant (lignin content reduced by 30% compared with WT) also showed the freezing tolerant phenotype, and TCF1 and BCB act upstream of PALs to regulate lignin content. In addition, TCF1 acts independently of the CBF (C-repeat binding factor) pathway. Our findings delineate a novel molecular pathway linking the TCF1-mediated cold-specific transcriptional program to lignin biosynthesis, thus achieving cell wall remodeling with increased freezing tolerance.

Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae) is a pupal parasitoid of drosophila flies recorded from several parts of the world. It is currently considered for augmentative biological programs to control the severe agricultural pest Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). Since D. suzukii has invaded regions that experience zero and sub-zero winter temperatures, cold tolerance of the parasitoid is an important aspect to consider. We characterized low temperature tolerance and overwintering capacity of a colony of T. drosophilae collected in Northern Switzerland. We used copper-constantan thermocouples to determine the supercooling point and pre-freeze mortality. Moreover, we subjected honey-fed and unfed adult T. drosophilae as well as developing stages within their drosophila host to short- and long-term acclimation conditions and assessed the duration of their survival at low temperatures. Finally, we exposed adult and sub-adult stages to winter conditions in a semi-field experiment and evaluated their survival. We found that T. drosophilae is chill susceptible like D. suzukii, but adults froze and survived at colder temperatures than those reported for D. suzukii. Adult parasitoids could tolerate several days of exposure to sub-zero temperatures and could reproduce afterwards, whereas sub-adult stages could survive longer periods under these conditions. The provision of honey and water enhanced the survival of adults and long-term acclimation led to longer survival in all stages. The semi-field experiment supported the results of the laboratory tests. Based on these results we suggest that in Central Europe, T. drosophilae survives winters mainly in developing stages but adults are likely able to tolerate short periods of low spring temperatures.
