    Notes: Granulomatous slack skin is a rare variant of indolent cutaneous lymphoma, characterized by a cutis laxa-like clinical appearance and widespread granulomatous infiltration. A 25-year-old man had suffered from slowly progressive infiltrative, scaly and atrophic plaques and flaccid nodules with deep induration in the axillae, trunk and thighs. Histopathologically, dense lymphoid cell infiltration with numerous multinucleated giant cells (MGC) throughout the dermis to the subcutaneous tissue was observed. T-cell receptor gene rearrangement was detected in the skin lesions. Granulomatous infiltration with MGC was found in enlarged lymph nodes and the liver. Acute exacerbation was successfully treated with systemic recombinant interferon-gamma.

    Notes: Chemotherapy-induced acral erythema (CAE) is an uncommon and distinct reaction seen in patients receiving high-dose chemotherapy. The exact pathogenic mechanisms of this disorder are still unknown. We report a 27-year-old woman who presented with red, swollen and painful macules on both palms, clinically consistent with this disease. Histological examination demonstrated vacuolar degeneration of the basal cell layer and spongiotic blisters in the epidermis, especially in the atrophied eccrine ducts and papillary oedema with mild perivascular infiltration of mononuclear and hypersegmented neutrophils. Immunohistochemistry showed that the infiltrating mononuclear cells were CD3–CD16+CD56+ leucocyte function antigen-1+, possibly natural killer cells. The eccrine ducts expressed HLA-DR and intracellular adhesion molecule-1 (ICAM-1). Our findings suggest that cell-to-cell interaction between NK cells and keratinocytes in the eccrine apparatus may induce CAE and may be involved in the pathogenesis of the skin reaction in our patient and possibly in this disease.

    Notes: Localization of a locus for atopy to chromosome 16p12–p11 and reported associations of Ile50Val and Gln551Arg polymorphisms in interleukin-4 receptor α chain (IL 4R gene) with atopy prompted us to sequence the gene in 27 adult atopic dermatitis (AD) and 29 non-atopic (non-AD) subjects. Among six known polymorphisms, Gln551Arg was significantly associated with AD (P = 0·01). This polymorphism was found to be heterozygous in six of 27 patients with AD but none of the 28 non-AD controls. Ile50Val, which was previously reported to be associated with atopic asthma in Japan, showed no association with AD in our group. Glu375Ala and Cys406Arg also showed no association with AD. The IL 4R gene should thus be considered a compelling candidate gene for AD.

    Notes: Abstract Background. The effectiveness of adjuvant chemotherapy for colorectal cancers after curative resection has been reported recently; this study was performed to clarify the reasons of for this effectiveness, which have been unclear. Methods. Two joint prospective clinical randomized studies were performed. In the first study, of patients operated on between July 1, 1981 and June 30, 1983, at 41 Centers in the Tokai district, 172 patients with colorectal cancer were allocated to two groups. In the control group, mitomycin C (MMC) was given eight times intravenously in the 4 weeks after surgery. The other group, in addition to receiving the same regimen as the controls, received oral administration of 1-hexylcarbamoyl-5-fluorouracil (HCFU) at 600 mg/day for at least 6 months after the 4-week MMC treatment. In the second study of patients operated at 7 Centers in the Tokai district between October 1, 1987 and September 30, 1990, 173 patients with colorectal cancer were allocated to two groups after surgery, a control group receiving no HCFU, the other group receiving HCFU at 0.8 mg/kg per day orally, for 1 year, beginning 4 weeks after the operation. Results. In the first study, the cumulative 10-year survival rate of the MMC + HCFU group was higher than that of the MMC-alone group (P 〈 0.05). In the second study, the cumulative 5-year disease-free survival rate of the HCFU group was higher than that of the control group (surgery alone; P 〈 0.05). In patients with colon cancers, the rate of distant metastases for all evaluable patients was lower in the MMC + HCFU group than in the MMC-alone group in the first study (P 〈 0.05), and the rate was lower in the HCFU group than in the surgery-alone group in the second study (P 〈 0.02). Conclusion. The effectiveness of HCFU in reducing the disease-free survival rate appeared to be mainly due to its preventive effect on distant metastases.

    Notes: Abstract The field-aligned neutral oscillations in the F-region (altitudes between 165 and 275 km) were compared using data obtained simultaneously with two independent instruments: the European Incoherent Scatter (EISCAT) UHF radar and a scanning Fabry-Perot interferometer (FPI). During the night of February 8, 1997, simultaneous observations with these instruments were conducted at Tromsø, Norway. Theoretically, the field-aligned neutral wind velocity can be obtained from the field-aligned ion velocity and by diffusion and ambipolar diffusion velocities. We thus derived field-aligned neutral wind velocities from the plasma velocities in EISCAT radar data. They were compared with those observed with the FPI (λ=630.0 nm), which are assumed to be weighted height averages of the actual neutral wind. The weighting function is the normalized height dependent emission rate. We used two model weighting functions to derive the neutral wind from EISCAT data. One was that the neutral wind velocity observed with the FPI is velocity integrated over the entire emission layer and multiplied by the theoretical normalized emission rate. The other was that the neutral wind velocity observed with the FPI corresponds to the velocity only around an altitude where the emission rate has a peak. Differences between the two methods were identified, but not completely clarified. However, the neutral wind velocities from both instruments had peak-to-peak correspondences at oscillation periods of about 10–40 min, shorter than that for the momentum transfer from ions to neutrals, but longer than from neutrals to ions. The synchronizing motions in the neutral wind velocities suggest that the momentum transfer from neutrals to ions was thought to be dominant for the observed field-aligned oscillations rather than the transfer from ions to neutrals. It is concluded that during the observation, the plasma oscillations observed with the EISCAT radar at different altitudes in the F-region are thought to be due to the motion of neutrals.

    Notes: Abstract. Although the assessment of right ventricular (RV) function is important in the clinical management of children with congenital heart disease, available imaging techniques have been limited because of the complex geometry of the right ventricle. A new Doppler index combining systolic and diastolic time intervals (the Tei index) has been reported to be useful for the assessment of global RV function in adults. However, normal values in children, age-related changes, and the clinical utility of the Tei index with regard to congenital heart disease have not been demonstrated. The purpose of this study was to prospectively assess RV function in children with normal heart and congenital heart disease using the Tei index. The subjects included 150 healthy children and 43 patients with congenital heart disease (35 patients with atrial septal defects and 8 patients who had had a Senning operation). The index was defined as the sum of isovolumetric contraction time and isovolumetric relaxation time divided by ejection time and was measured from conventional RV outflow and inflow Doppler velocity profiles. The Tei index was not affected by age in healthy children (0.24 ± 0.04). There was a significant difference in index rating between patients who had had a Senning operation (0.58 ± 0.09) and healthy children (p 〈 0.01), but there was no significant difference between children with atrial septal defect (0.25 ± 0.13) and healthy children. The Tei index is a feasible approach to use when assessing global RV function in children with congential heart disease.
