Five‐year efficacy of finasteride in 801 Japanese men with androgenetic alopecia

Finasteride is standard medical treatment for androgenetic alopecia; however, no large studies with 5 years or more of follow up have been performed in Japan. The authors followed Japanese men with androgenetic alopecia treated with finasteride for 5 years to evaluate long‐term treatment efficacy. Of 903 men treated with finasteride (1 mg/day), 801 patients were evaluated over 5 years by modified global photographic assessment. Although the proportion of improvement was high (99.4%), modified global photographic assessment scores after 5 years of treatment were lower in patients with more advanced disease as measured by the modified Norwood–Hamilton scale. After separating patients into “sufficient” and “insufficient” efficacy groups according to the modified global photographic assessment score after 5 years (scores ≥6 and <6, respectively), multivariate analysis showed that independent risk factors of insufficient efficacy were age at start of treatment of 40 years or more (P = 0.021) and classification on the modified Norwood–Hamilton scale (P < 0.001), whereas presence of stress at start of treatment was a negative predictor (P = 0.025). In conclusion, continuous finasteride treatment for 5 years improved androgenetic alopecia with sustained effect among Japanese. Younger age and less advanced disease at start of treatment were the key predictors of higher finasteride efficacy.     

A case of drug eruption induced by hydroxyzine pamoate]

A 62-year-old woman with rheumatoid arthritis, Basedow's disease and arrhythmia has been treated with antirheumatic, antiarrhythmic drugs and so on. She developed pruritic diffuse erythema with papules on the trunk and extremities 2 days after taking hydroxyzine pamoate for asteatotic eczema. Laboratory data showed increased levels of eosinophils. Histopathological examination revealed a infiltrate of inflammatory cells in the upper dermis. Patch tests with hydroxyzine pamoate and hydroxyzine hydrochloride were positive. From these findings, we diagnosed this case as drug eruption due to hydroxyzine. Her eruption subsided after she discontinued hydroxyzine pamoate and other drugs which were started within 5 days before the onset of the eruption and was treated with systemic steroid, systemic antiallergic drug and topical steroid.     

Classification of Diabetes Mellitus by Studies of C-Peptide Secretory Capacity

Residual pancreatic B-cell function was investigated in children with diabetes mellitus in whom classification of the type of disease was difficult at the first visit. Intravenous glucagon tests were performed at the first visit and subsequently, the C-peptide responses compared. Based on our data on a limited number of patients, we propose C-peptide concentrations of 3.0 to 3.5 ng/ml at the peak or at 6 min after injection of glucagon, as the critical level which distinguishes non-insulin dependent from insulin-dependent diabetes mellitus. However, the degree of obesity, clinical stage and other factors also need to be considered in the classification of diabetes mellitus.     

Successful Treatment of Adult T-cell Leukemia/Lymphoma with MACOP-B,M-FEPA and VEPP-B Combination Chemotherapy

A 45-year-old man was referred to our department in March of 1989. Physical examination showed erythroderma, palmo-plantar hyperkeratosis, generalized lymphadenopathy, hepatosplenomegaly, and leukemic manifestation. The lymphocyte count in the peripheral blood before treatment was 1.7 × 10⁴ cells/mm³. Atypical lymphocytes such as flower cells and lobulated cells were seen in the peripheral blood. A sample excised from a lymph node showed immunoblastic, pleomorphic T cells by a modified classification scheme of the Working Formulation. A high level of serum LDH was detected (2.1 times the upper normal limit). Anti HTLV-1 antibody was also detected in the serum. The atypical lymphocytes were positive for CD3, CD4, CD5, CD7 and HLA-DR, and negative for CD8. Thus, the clinical, pathologic and immunologic features were those of typical acute-type ATL. The patient was treated with VEPA-M for three months starting in March of 1989. Because of poor response, the patient was then treated with MACOP-B, M-FEPA, and VEPP-B for about one year from June of 1989 and has been free of disease up to the time of writing, March of 1993.     

Hydrops Fetalis Caused by Fetal Kasabach-Merritt Syndrome

There have been only 2 previous reports of nonimmunologic hydrops fetalis (NIHF) caused by fetal Kasabach-Merritt syndrome, both of which were pathological studies. This is the first clinical case report of NIHF due to fetal Kasabach-Merritt syndrome that was prenatally diagnosed by sonography, computerized tomography, and percutaneous umbilical blood sampling.     

Thoracoscopic closure of a congenital partial pericardial defect

We describe our technique for performing direct thoracoscopic closure of a congenital partial pericardial defect, which was successfully employed in a 15-year-old boy. This is the first such report of a procedure that is noninvasive and may therefore become the treatment of choice for patients with a small congenital pericardial defect.     

Noninvasive Nasal Mask BiPAP Management for Prolonged Respiratory Failure Following Cardiovascular Surgery

A bstract The purpose of this study was to assess the efficacy of nasal mask bi-level positive airway pressure (BiPAP) support in managing respiratory failure following cardiovascular surgery. A total of 20 patients requiring postoperative prolonged respiratory support of 72 hours or longer were studied. BiPAP support was used for eight patients (BiPAP group); the other 12 patients were managed using ordinary oxygen mask treatment (control group). The mean age of the BiPAP group and control group was 65 and 58 years of age, respectively. The mean period of postoperative endotracheal intubation of the BiPAP group and control group was 12 ± 5 days and 7 ± 1 days, respectively. Reintubation was necessary in two patients of the control group. The BiPAP group patients required no reintubation. BiPAP support was discontinued within 48 hours in 6 out of 8 patients. The respiratory rates of control group increased (p < 0.1) 24 hours after extubation, however, the respiratory rates of the BiPAP group remained unchanged. The values of the respiratory index of the BiPAP group improved significantly (p < 0.01) after BiPAP management (from 1.5 ± 0.2 to 0.9 ± 0.2). The values of the control group, however, remained unchanged. A-aDO₂ and Qs/Qt decreased (p < 0.1) in the BiPAP group. There were no significant differences in central venous pressure or circulatory status between the two groups. In conclusion, BiPAP support is a noninvasive management technique for postoperative respiratory failure and may also prevent prolonged endotracheal intubation.     

Prevention of Acute Lung Allograft Rejection in Rat by CTLA4Ig

CTLA4 immunoglobulin (CTLA4Ig), which binds with a high affinity to B7-1 and B7-2, interrupts T-cell activation by inhibiting costimulatory signal. CTLA4Ig has been used in hopes of achieving antigen-specific tolerance induction in several solid organ transplants. In lung allograft rejection, however, its use has been controversial in terms of its effect on prevention of rejection. In the present study, the effect of murine CTLA4Ig on rat-lung allograft rejection was investigated. Rat left-lung transplantation was performed in an RT1 incompatible donor (Brown Norway; BN)-recipient (F344) combination. All allografts (n = 12) without any treatment were rejected within 7 days after transplantation. A single injection of murine form CTLA41g at a dose of 100 microg intraperitoneally (ip) or intravenously (iv) on day 1 post-transplantation achieved long-term graft survival (>90days) in 2/5 (40%) and 3/8 (38%), respectively. Moreover, 6/7 (86%) allografts in rats that received iv injection of 500 microg CTLA4Ig survived more than 90days. Allograft survival in the CTLA4Ig 500 microg iv recipient group was significantly longer than that in the no-treatment control or control immunoglobulin group (p <0.01). Four out of seven recipients bearing functional allografts for more than 90 days with the CTLA4Ig treatment accepted donor-specific skin grafts, whereas all third-party skin grafts (n=3) were rejected. Prevention of rat-lung allograft rejection could be achieved by intravenous administration of CTLA4Ig, resulting in long-term allograft survival with acceptance of donor-specific skin grafts.     

Plasma thrombomodulin level in very low birthweight infants at birth

Objective: Plasma soluble thrombomodulin level reflects endothelial damage. The plasma thrombomodulin level at birth is increased in asphyxiated full-term infants. There is no report of plasma thrombomodulin level in premature infants. To determine the thrombomodulin level in premature infants and whether it might reflect endothelial damage, we examined the plasma thrombomodulin level in very low birthweight (VLBW) infants at birth. Methods: Forty-five VLBW infants, of whom 14 had perinatal asphyxia complications, were recruited. As a control, 50 full-term infants wimout complications were also studied. Plasma thrombomodulin concentration, pH, base deficit, serum creatinine and D-dimer concentration, platelet count and fibrinogen concentration were measured within 1 hour after birth. Results: There were significant differences in plasma pH, creatinine concentration, platelet count, antithrombin in activity and D-dimer concentration between VLBW infants and full-term infants. Plasma thrombomodulin concentration (39. 0 (16. 6–93. 7) vs 27. 0 (16. 6–39. 1) μg/L, p < 0. 0001) and plasma taombomodulin-to-serum creatinine ratio (0. 82 (0. 19–2. 65) vs 0. 47 (0. 24–0. 70) μg/μmol, p < 0. 0001) were significantly higher in VLBW infants than those in full-term infants. By univariate analyses for all neonates, there were significant relations between plasma thrombomodulin concentration and gestational age, birthweight, plasma pH, creatinine concentration, platelet count and antithrombin in activity. A stepwise multiple linear regression model using the above variables as dependent factors showed only birthweight contributed significantly to plasma thrombomodulin concentration (plasma thrombomodulin concentration (μg/1) = 45. 677–0. 006 (birthweight; g), r²= 0. 323, p < 0. 0001, n= 94). Plasma thrombomodulin concentration and plasma thrombomodulin-to -serum creatinine ratio in VLBW infants with asphyxia were higher than in those without asphyxia, but not significantly different (43. 2 ± 17. 7 vs 38. 3 ± 8. 5 μg/1 and 0. 92 ± 0. 60 vs 0. 83 ± 0. 37 μg/μmol). Conclusion: Plasma thrombomodulin level in VLBW infants shows a high value at birth, and we consider the main factor responsible for this elevation may be endothelial damage or low clearance rate of thrombomodulin, which may be related to early gestational age.
