The care of infants menaced by cocaine abuse.
The newborn's symptoms of prenatal drug exposure threaten attachment. Consequently, psychosocial progress is impeded. Early intervention provides hope for these infants.

Monitoring poultry farms for Salmonella by drag-swab sampling and antigen-capture immunoassay.
Drag-swab (DS) sampling, at the rate of four DS gauze pads per flock (house); modified culture procedures (novobiocin-supplemented plating media and delayed secondary selective enrichment); and Salmonella antigen-capture (SAC) technology were combined in screening one layer flock and 38 market-age broiler flocks. The results showed that low (negative) SAC sample-to-positive control (S/P) ratios were related to the negative culture recovery of Salmonella. Similarly, high (positive) S/P ratios were related to and indicative of positive culture recoveries. Extensive sampling and testing of 18 of the 39 flocks disclosed A) that five flocks with negative culture recoveries from feathers and freshly voided feces had essentially no positive DS-SAC values, and B) that 13 flocks with positive culture recoveries from feathers and/or fresh feces all had positive DS-SAC values.

Immunophenotyping of leukaemias by flow cytometry and APAAP: a two-year comparative analysis in hospital practice.
Using a panel of monoclonal antibodies for the immunophenotyping of haematological malignancies, we have made a direct comparison of the usefulness of indirect immunofluorescence using flow cytometry (IFC) alongside the alkaline phosphatase-anti-alkaline phosphatase (APAAP) immunoenzyme method. Analysis of 400 consecutive patient samples (blood and bone marrow) over a 2-year period, resulted in unequivocal phenotyping agreement by both methods in 98 per cent of cases. The positive results accounting for 2 per cent discordance were obtained by the APAAP method. The value of the technique in the clinical management of patients with leukaemia is documented together with guidelines for clinical laboratories.

Neoplasms of the mononuclear phagocyte system: criteria for diagnosis.
The Mononuclear Phagocyte System, including promonocytes, monocytes, and tissue histiocytes (macrophages), gives rise to moncytic leukaemias and histiocytoses. A classification of these neoplasms by their presumed cell of origin is proposed, and criteria for their diagnosis are given. Histopathological, cytochemical, immunological and ultrastructural features useful in distinguishing these disorders form other haematopoietic or lymphoid neoplasms are presented in detail. The resulting classification reflects our knowledge at this time; as techniques become available to define further functional subpopulations of mononuclear phagocytes, it is likely that this classification will become as diverse as that of lymphoid neoplasms.

[Fabry's disease without cutaneous angiokeratoma : diagnosis by electron microscope study of skin biopsy (author's transl)].
A case of Fabry's disease without typical skin lesion is reported. Electron microscope study of normally appearing skin (at clinical and even histological levels) has shown typical inclusions within cytoplasm of various dermic cells (endothelial cells and pericytes, myocytes, fibroblasts) and adipocytes. These inclusions are made up of stacks of membranes with parallel array and periodicity about 5 nanometers. Such a case emphasizes usefulness of electron microscopy of skin, even normally appearing, for the diagnosis of Fabry disease, as it has been previously shown for other dyslipidoses.

Recovery of Salmonella species from nonfat dry milk rehydrated under rapid and reduced pre-enrichment conditions: collaborative study.
A collaborative study was conducted to compare the relative efficiency of the AOAC rapid rehydration method with the reduced rehydration soak method for the recovery of Salmonella species from nonfat dry milk (NFDM). In the AOAC method, a 25 g sample of NFDM is rapidly rehydrated at a 1:9 sample/water ratio and mixed by swirling. After 60 min, the flask contents are adjusted to a pH of 6.8, and 0.45 mL of 1% aqueous brilliant green dye solution is added. The flasks are then incubated at 35 degrees C. In the soak method, a 25 g sample of NFDM is gently added to the sterile brilliant green (BG) water at a 1:9 sample/BG water ratio and allowed to soak undisturbed for 60 min at room temperature before incubation. Twelve collaborators analyzed 3 shipments of samples with the following results for the AOAC and soak methods: shipment 1-31 and 46 positive samples, respectively, with a 48% increase in detection by the soak method; shipment 3-45 and 66 positive samples, respectively, with a 47% increase in detection by the soak method; shipment 2--no significant difference in recovery of Salmonella species by the 2 methods. It is recommended that the official final action method for the detection of Salmonella species, 46.054-46.067, be revised to use the soak method for the analysis of nonfat dry milk.

Enumeration of total coliforms, fecal coliforms, and Escherichia coli in foods by hydrophobic grid membrane filter: collaborative study.
A collaborative study was conducted in 18 laboratories to assess the performance of the hydrophobic grid membrane filter method against that of the AOAC official first action method 46.013-46.016 for enumerating total and fecal coliforms and Escherichia coli. The study was carried out on frozen breaded fish, raw comminuted poultry, unroasted walnut pieces, ground black pepper, and cheddar cheese. The hydrophobic grid membrane filter method recovered significantly larger numbers of target bacteria in 7 of the food/analysis combinations: fecal coliforms in fish; E. coli in poultry; fecal coliforms and E. coli in walnuts; and total coliforms, fecal coliforms and E. coli in black pepper. Random error (Sr2) associated with the hydrophobic grid membrane filter method was significantly lower than that of the reference method in over 30% of the paired sample series. The hydrophobic grid membrane filter method for total coliform, fecal coliform, and E. coli enumeration in foods has been adopted official first action.

Evaluation of battery-operated monitor/defibrillators used in prehospital care.
During the past two decades, prehospital medical care has become more sophisticated, resulting in devices that are routinely used in the hospital being adapted for use in the field. One such device is the ECG machine, which has undergone extensive technological and performance modifications so it may better serve the large number of patients requiring electrocardiographic monitoring and cardioversion in stressed environments.
