    Notes: Primary extramammary Paget's disease is thought to be an intraepidermal carcinoma indicating apocrine secretory differentiation. In addition to expression in breast tissue, human milk fat globulin (HMFG) is expressed in the normal apocrine glands and tumours with apocrine differentiation. In this study HMFG expression in extramammary Paget's disease was analysed immunohistochemically in 18 cases of primary extramammary Paget's disease and two cases of secondary extramammary Paget's disease. The proportion and staining pattern of positive tumour cells with the anti-HMFG antibody was variable in each case. Cytoplasmic staining was observed frequently in dermal invasion and metastasis of Paget cells. The variabilities were thought to be due to modulation of the cellular localization of the cell surface component, HMFG, according to changes in cellular differentiation or malignant potency.

    Notes: Because median raphe cyst of the penis shares histological findings with apocrine cystadenoma, some cases were thought to be erroneously reported as apocrine cystadenoma of the penis. Further, there is some controversy as to whether the entity, apocrine cystadenoma of the penis, exists or not. Nine cases of median raphe cyst which were clinically unequivocal from their location on the ventral aspects of the penis, were analysed immunohistochemically by using an antibody against human milk fat globulin 1 (HMFG) and a panel of monoclonal anti-cytokeratin antibodies. HMFG expression was not observed in eight out of nine cases of median raphe cyst of the penis, and the remaining case showed a faint expression of HMFG focally in its luminal surface, while conventional apocrine cystadenoma in extra-genital area expressed HMFG definitively in our previous study. Our results suggest a possibility that apocrine cystadenoma of the penis is very rare or not present. Therefore, we thought that HMFG expression should be examined in the cases in which apocrine cystadenoma on the penis is reported.

    Notes: Despite the similarity in clinical appearance, there is a significant difference in the prognosis between primary extramammary Paget’s disease (EPD) and the pagetoid spread of underlying regional internal malignancy (secondary EPD, pagetoid phenomenon). Fifteen cases of primary EPD (11 carcinoma in situ and four invasive carcinoma), seven cases of secondary EPD (five colorectal adenocarcinoma and two urothelial carcinoma), and six cases of anal canal carcinoma were retrieved and analysed immunohistochemically using six kinds of monoclonal anticytokeratin antibodies. No expression of cytokeratins 1, 5, 10, 13 and 14 was observed in any cases examined in this study. All 15 cases of primary EPD had the immunophenotype cytokeratin (CK)7+/CK20–. CK20 expression was diffusely positive in six cases of secondary pagetoid spread (two urothelial carcinoma and four colorectal adenocarcinoma), and focally in one case (a colorectal adenocarcinoma). In anal canal carcinoma, three of six cases showed CK20 diffuse expression and the remaining three cases expressed CK20 focally. CK7 expression was observed in three of six cases of anal canal carcinoma and in two of five cases of secondary EPD associated with colorectal adenocarcinoma. The combination of CK7 and CK20 demonstrates these to be useful markers in distinguishing ‘primary’ EPD from a pagetoid spread of extracutaneous malignancies. Namely, immunophenotypes other than CK7+/CK20– in Paget cells suggest underlying regional internal malignancy.

    Notes: —In order to study changes of the glycolytic-respiratory system and amino acid metabolism associated with blood flow disturbance, the cat brain perfusion was conducted with artificial blood containing [U-14C]glucose and the results were compared with those of standard perfusion keeping the cerebral blood flow at constant rate. The findings of the present study are briefly summarized:(1) In blood flow disturbance there was observed an accumulation of lactate just as seen in the low functional state observable in the standard perfusion. However the increase in relative specific activity of lactate was not so marked as the rise in cerebral lactate content, and this indicates that there is an increase of lactate production from substrates other than glucose as well as an increase of net flow of glucose carbon to lactate.(2) In blood flow disturbance relative specific activities of glutamate, aspartate, glutamine and respiratory CO2 were decreased as compared with those in the brain of high functional state. The relative specific activity of GABA in the reduced blood flow brain was at the same level as that of the brain at high functional state and it was higher than the relative specific activity of glutamate.(3) The relative specific activity and content of alanine were increased in the low function brain with standard perfusion.

    Notes: We have tested the hypothesis that intubation success rates, haemodynamic changes, airway complications and postoperative pharyngolaryngeal morbidity differ between blind and lightwand-guided intubation through the intubating laryngeal mask airway. One hundred and twenty paralysed anasthetised adult patients (ASA I–II, no known or predicted difficult airways) were assigned in a random manner to one of two equal-sized groups. In the blind group, patients were intubated blindly through the intubating laryngeal mask airway. In the lightwand group, patients were intubated through the intubating laryngeal mask airway assisted by transillumination of the neck with a lightwand. A standard sequence of adjusting manoeuvres was followed if resistance occurred during intubation or if transillumination was incorrect. The number of adjusting manoeuvres, time to intubation, intubation success rates, haemodynamic changes (pre-induction, pre-intubation, postintubation), oesophageal intubation, mucosal trauma (blood detected), hypoxia (oxygen saturation 〈 95%) and postoperative pharyngolaryngeal morbidity (double-blinded) were documented. Overall intubation success was similar (blind, 93%; lightwand, 100%), but time to successful intubation was significantly shorter (67 vs. 46 s, p = 0.027) and the number of adjusting manoeuvres was significantly fewer (p = 0.024) in the lightwand group. There were no significant differences in blood pressure or heart rate between the groups at any time. Oesophageal intubation occurred more frequently in the blind group (18 vs. 0%, p = 0.002). The incidence and severity of mucosal injury, sore throat and hoarseness were similar between the groups. We conclude that lightwand-guided intubation through the intubating laryngeal mask is superior to the blind technique.

    Notes: Background: While squamous cell carcinoma and pseudocarcinomatous hyperplasia have been documented as pre-existing lesions in cases of reactive eccrine syringofibroadenoma (ESFA), to the best of our knowledge carcinoma occurring in a solitary ESFA has not yet been reported. We present one such case in a 91-year-old female who had a dome-shaped, reddish tumor on the extensor side of the left forearm.Methods: We review the histopathological, immunophenotypical and ultrastructural findings of this tumor, including the keratin expression profile.Results: Histopathologically, long, branching, anastomosing, thin and thick strands of small cuboidal epithelial cells were extending from the surface epidermis into the dermis. In the center of the tumor, there were irregular-shaped nests of atypical tumor cells invading downward into the dermis. Ultrastructurally, duct-like lumina lined with cuboidal tumor cells were present in the epithelial cords. From these findings, the present case was diagnosed as solitary eccrine syringofibroadenocarcinoma (ESFAC). Keratin expression studies revealed that cells of the thick strands, except for the luminal and basal cells, were positive for differentiation-specific keratins, keratins 1 and 10, and that cells of the thin strands were positive for keratins 5 and 14.Conclusions: Histopathological, immunophenotypical and ultrastructural evidence, as well as the pattern of keratin expression, suggest differentiation of the present malignant tumor towards the eccrine dermal duct. This case is the first reported case of ESFAC as far as we know.

    Notes: Background Regulated on activation, normal T cells expressed and secreted (RANTES) is a member of the CC chemokine family and contributes to viral-induced airway inflammation including exacerbations of asthma. Double-stranded RNA (dsRNA) is known to be synthesized during replication of many viruses and a ligand of Toll-like receptor 3. We hypothesized that dsRNA may mimic viral infection and induce RANTES expression in airway epithelial cells.Objective We first confirmed that dsRNA up-regulated RANTES mRNA and protein synthesis in the airway epithelial cells. We next focused our studies on the transcriptional regulation of RANTES.Methods Airway epithelial cell line BEAS-2B and normal human bronchial epithelial cells were used in vitro study. Levels of RANTES mRNA and protein expression were determined with RT-PCR and ELISA. Mechanisms of transcriptional regulation were assessed by electrophoretic mobility shift assay and dual luciferase assay using RANTES promoter-luciferase reporter plasmids.Results Activation of nuclear factor-κB (NF-κB) was confirmed by nuclear protein binding to a DNA probe derived from the RANTES promoter. Activity of the RANTES promoter was increased by dsRNA. The stimulation with dsRNA was partially inhibited in plasmids mutated at either of the binding sites for NF-κB or IFN regulatory factors (IRFs). When both sites were mutated, the activation was totally abrogated.Conclusion These results imply that dsRNA activates NF-κB and IRFs and these transcription factors activate transcription of the RANTES promoter and its protein expression in airway epithelial cells.

    Notes: Background It is suggested that skin fungi may be involved in the development of atopic dermatitis (AD) and psoriasis vulgaris (PV).Objective We studied skin fungus-induced Th1- or Th2-related cytokine, chemokine and prostaglandin E2 (PGE2) secretion in peripheral blood mononuclear cells (PBMC) from patients with AD and PV and normal subjects.Methods PBMC were cultured with the extracts of Malassezia furfur (MF), Candida albicans (CA) and Trichophyton rubrum (TR). The cytokine, chemokine and PGE2 amounts in the supernatants were measured by enzyme-linked immunosorbent assays.Results MF induced IL-4 and macrophage-derived chemokine (MDC) secretion in AD patients, while induced IFN-γ and interferon-inducible protein of 10 kDa (IP-10) secretion in PV patients, however, did not induce either secretion in normal subjects. CA induced IL-4, MDC, IFN-γ and IP-10 secretion in AD and PV patients and normal subjects. In AD patients, the magnitude of IL-4 and MDC responses to CA was higher than that to MF. Compared with PV patients and normal subjects, the magnitude of IL-4 and MDC responses to CA was higher while that of IFN-γ and IP-10 responses to CA was lower in AD patients. TR induced moderate IL-4 and MDC secretion only in AD patients. The three fungi induced higher levels of PGE2 secretion in AD patients than in PV patients and normal subjects. Cyclooxygenase-2 inhibitor NS-398 suppressed PGE2 responses to MF, CA and TR, and partially suppressed IL-4 and MDC responses to MF, CA and TR, while enhanced IFN-γ and IP-10 responses to CA in AD patients, and these effects of NS-398 were reversed by cyclic AMP analogue.Conclusion AD patients manifest Th2-skewed responses to MF, CA and TR, which may be partially attributable to the enhanced PGE2 responses to these fungi. PV patients manifest Th1-skewed responses to MF.
