    Notes: This study investigated the mixed alkali effect in a series of phosphate based glasses. Theseglasses were of the composition 0.5P2O5-0.2CaO-0.3-xNa2O-xK2O where x=0 to 0.3 in steps of 0.05.This study considered density measurements using Archimedes’s principle, thermal characterisation usingdifferential scanning calorimetry, phase analysis following crystallisation using X-ray powder diffraction(XRD), and degradation studies combined with ion release. The results showed that these mixed alkaliglasses showed a linear decrease in density, with the ternary single alkali glass with 0.3mol K2O showinga 3% reduction in density as compared to that with 0.3mol Na2O which correlated well with thedifference in ionic diameter and atomic weight of both cations. These glasses also showed intermediateglass transition temperature (Tg) values, compared to those of the ternary single alkali glasses having thesame alkali oxide content, and the minimum Tg value was recorded for equimolar amounts of both alkalioxides. However, they did not show any significant change in the degradation rate compared to the glasswith 0.3mol Na2O with the exception of the 0.25mol K2O glass. The single alkali glass with 0.3mol K2Oshowed a significant increase in the degradation rate by an approximate one order of magnitude. For themixed alkali glasses with low molar concentration of K2O, only sodium phosphate-rich phases[NaCa(PO3)3 and Na4Ca(PO3)6] were detected from XRD; at high molar concentrations however,potassium phosphate-rich phases [KCa(PO3)3 and KPO3] were detected. At equimolar concentration ofboth alkali cations, KCa(PO3)3 and Na4Ca(PO3)6 were identified. K+, Ca2+, and P3O93- release followedthe degradation behaviour where the highly degrading glasses with 0.25 and 0.3mol K2O released thehighest amount of these ions; however, there was no definite trend in the remaining glass compositions

    Notes: To evaluate the hypothesis that reactivity of the intradermal component of melanocytic nevi to the monoclonal antibody HMB-45 correlates with melanoma risk, dysplastic compound melanocytic nevi were examined for expression of the HMB-45 epitope in three subject groups differing in epidemiological risk for melanoma. The study groups consisted of 10 subjects with dysplastic nevi and a personal history of melanoma, 25 subjects with dysplastic nevi and a history of melanoma in one or more first degree relatives, and 15 population control subjects with sporadic dysplastic nevi. For each case, sections from one lesion, immunohistochemically processed for HMB-45 binding, were evaluated by two pathologists without knowledge of the clinical data. Of all dysplastic nevi, 98% showed diffusely positive cytoplasmic staining of the junctional nevomelanocytes and 90% had such positive staining of those cells within the superficial dermis. Nevus cells within the deeper dermis did not stain positively in any case. Furthermore, the data showed no differences in frequency, pattern, or intensity of HMB-45 reactivity between the subject groups. These observations indicate that evaluation of dysplastic nevi with the monoclonal antibody HMB-45, an apparent marker of proliferative or otherwise stimulated melanocytes, has no discriminating value for identifying subjects at increased historical risk for melanoma. The data, however, support the concept that so-called dysplasia within nevi, as defined by histologic criteria, actually represents the active or proliferative phase of melanocytic nevi.

    Notes: Mammary-like glands are a poorly recognized structure of the normal vulvar skin. Adenocarcinomas occur rarely in these glands and represent a distinct clinicopathologic entity that must be distinguished from metastatic tumors. We present a case of a 51-year-old patient with a long-standing nodule on her right labium majus. Excision with subsequent Mohs micrographic surgery revealed an infiltrating adenocarcinoma of the mammary-like glands involving the dermis and subcutis. We review all cases thus far reported (including the case presented herein) and identify important clinical and morphologic features of this tumor. A significant histopathological and immunohistochemical overlap between this neoplasm, sweat gland carcinomas, and invasive extramammary Paget’s disease was recognized; suggesting the existence of a morphologic spectrum between these entities. Criteria for establishing the diagnosis of adenocarcinoma of mammary-like glands are reviewed, including the importance of identifying transition zones between normal mammary-like glands and malignant glands. We believe that this tumor is best categorized as a locally aggressive neoplasm with a low metastatic potential and death from disease is uncommon. The successful treatment of this case by Mohs micrographic surgery suggests that an alternate management approach may be adopted for these tumors, particularly in elderly patients.

    Notes: Dimorphic fungal infections (histoplasmosis, blastomycosis, coccidiomycosis, and cryptococcosis) can occur in immunocompromised and healthy individuals. Cutaneous involvement is often secondary and may be the presenting sign of systemic disease. These ominous infections are frequently clinically indistinct and their prognosis is influenced by their timely diagnosis and treatment. Morphological differentiation between these organisms is not definitive and tissue cultures represent the diagnostic gold standard in current day practice. However, not uncommonly tissue cultures are not obtained and merely represent an afterthought in seemingly unsuspecting cases. Furthermore, when performed, they may take several days to weeks for completion. In situ hybridization (ISH) utilizing oligonucleotide probes directed against fungal ribosomal RNA represents a rapid and accurate assay for the diagnosis of dimorphic fungi in paraffin-embedded tissue sections. We present 7 patients in whom ISH both prospecitively and retrospectively confirmed the presence of a cutaneous infection (2 histoplasmosis, 2 blastomycosis, 1 coccidiomycosis, 2 cryptococcosis). In all of the skin sections analyzed, dimorphic fungi were morphologically apparent but not diagnostically discernable. In summary, ISH represents a valuable tool in the prompt diagnosis of cutaneous deep fungal infections.

    Notes: [Auszug] There was a highly significant difference in body temperature and respiration-rate on different days and throughout the day due to different weather conditions between and during days. From Table 1 it will be seen that the mean body temperature and respiration-rate of the buffaloes was lower than ...
