Cutis marmorata telangiectatica congenita(CMTC) is a rare congenital cutaneous vascular anomaly. The major skin findings are persistent, fixed cutis marmorata, telangiectasia, and phlebectasia. In approximately 50 % of patients, the disorder tends to be associated with various con-genital anomalies. We describe in this report a 4-month-old male infant with CMTC. The patient had red or violet marbled patches, telangiectases, and atrophy on the right arm present at birth. During the follow up period of 12 months, there was no change in the cutis marmorata pattern and telangiectases, whereas the atrophy has been less prominent than at the initial visit.

BACKGROUND: The effects of a muscle relaxant may differ in elderly compared with young adult patients for a variety of the pharmacokinetic and pharmacodynamic reasons. Atracurium is eliminated by nonorgan dependent pathway, Hofmann elimination and ester hydrolysis. So there are some arguments for age-related differences. The purpose of this study was to compare the differences of the onset and duration of atracurium in young and elderly. METHODS: Eighteen young adults (21-54 yr) and 18 elderly (>65 yr) patients anesthetized with nitrous oxide and enflurane. Atracurium (0.5 mg/kg) was given and then intubation was performed after T1 response was blocked more than 80%. Neuromuscular relaxation was measured by the first twitch of train-of-four (T1) response at the adductor pollicis after supramaximal stimulation of ulnar nerve at 2Hz every 12 sec. The onset (disappearance of T1) and duration of 5, 25, 50, 75% recovery time of T1 and recovery index (time for 25-75% recovery of T1) were recorded. RESULTS: Onset of block was not significantly different between the young and elderly. Recovery time of 5, 25, 50, 75% and recovery index were not prolonged in elderly compared with young adults. CONCLUSIONS: There were no significant differences between young and elderly adults in onest time, recovery time of 5, 25, 50, 75% and recovery index when atracurium is used in a single bolus dose. The results suggest that atracurium in elderly patients has similar onset and action duration compared with younger patients.

Electron microscopic examination of specimens from lesions of eight patients with hyperpigmented and six patients with hypopigmented tinea versicolor and from unaffected skin in each patient was performed. The results are summarized as follows; 1. In hyperpigmented lesions, melanosomes are larger and more singly dispersed than in unaffected skin. 2. In hypopigmented lesions, melanosomes are smaller and less singly diepersed than in unaffected skin. 3. Number of total melanosomes in hyperpigmented and hypopigmented lesions was not different from in unaffected skin.

The currently proposed factors inducing prostatic hyperplasia are the combined effect of androgen and estrogen and the reawakening of the embryonic growth potential of mature prostatic stroma. This experiment was designed to find out any histological or structural differences occurring after compensating sex hormones on the mature prostate and the implanted fetal urogenital sinus (UGS) tissue which possesses a differentiating potential under the same condition. The ventral lobe of the rat prostate with implanted fetal UGS showed 4.4 fold increase in weight compared to the non-implanted contralateral ventral lobe. After the castration, both ventral lobes showed marked atrophy, and no further progress in differentiation occurred in the implanted UGS. Dihydrotestosterone (DHT) compensation after castration revealed a significant increase in weight in the mature prostate but the ventral lobe with the implanted UGS showed relatively low recovery rate in weight than in non-castrated control group. The compensation of estradiol after the castration showed little difference in mature prostate compared to castrated control group, but the UGS implanted ventral lobe revealed a relative stromal hyperplasia. Unlike the single-hormone compensation, the mature prostate displayed the characteristic hyperplasia of epithelium of each acinar lumen, but the UGS dearly showed the formation of new acini with nodular pattern when compensated with both DHT and estradiol. The level of DHT showed a significant correlation with the height of the prostatic acinar cell which differentiated from the UGS, and an inverse correlation with the stroma/epithelium ratio of implanted group. The serum concentration of estradiol showed a significant correlation with the relative volume of juxta-prostatic tissues, such as the coagulating gland and the adjacent stroma. From the above results, it might be assumed that the estrogen may have an important role in the embryonic stroma-mediated initiation of nodular hyperplastic changes of microacini under the influence of DHT and the determination of histologic pattern after initiation might be controlled by the prostatic DHT concentration.

In 2005, the ILAE conceptually defined epilepsy as a disorder of the brain, characterized by an enduring predisposition to generate epileptic seizures and by its psychosocial consequences. In clinical practice, this definition of epilepsy is usually taken to mean at least two unprovoked seizures more than 24 h apart. The operational definition for special circumstances that do not meet the criteria of two unprovoked attacks has been recommended. In 2014, the ILAE refined the practical definition of epilepsy. With this definition, epilepsy is a disease of the brain with either: (1) at least two unprovoked (or reflex) seizures occurring more than 24 h apart; (2) one unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after two unprovoked seizures, occurring over the next 10 years; (3) diagnosis of an epilepsy syndrome. Epilepsy is considered to be resolved for individuals past the applicable age of an age-dependent epilepsy syndrome or those who have remained seizure-free for the past 10 years, without seizure medicines for the past 5 years.

Inadequate effectiveness of anticancer drug in treating renal cell carcinoma has been attributed to the overexpression of multidrug resistance gene (MDR1) and its product, membrane-bound P-glycoprotein. P-glycoprotein is known to actively pump out intracellular drug, which results in low intracellular anticancer drug concentration. Progesterone, which has been used in patients with advanced renal cell carcinoma is found to cause a three to four-fold increase in vinblastine accumulation in the P-glycoprotein-expressing murine macrophage-like cell line.We have studied to evaluate the MDR modulating action of medroxyprogesterone acetate (MPA) in renal cell carcinoma cell lines also with tamoxifen and verapamil. A-498 of a high mdrl expressed cell line and Caki-2 of a low mdrl expressed cell line were each placed in 96 multiwell plates. Vinblastine, in concentration from 0.01 ug/ml to 10 ug/ml was added to each well and verapamil, from 0.1 uM to 10 uM, MPA, from 2.5 uM to 25 uM, or tamoxifen, from 0.1 uM to 10 uM was also added. The in vitro chemosensitivity of two renal cell carcinoma cell lines (Caki-2 and A498) to vinblastine was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazol bromide(MTF) colorimetric assay. Growth of Caki-2 cells is inhibited by low doses of vinblastine(IC50: 0.27 ug/ml), but A-498 cells are highly resistant to the drug, with ICs0 value of 0.47 ug/ml. The chemosensitivity of the A-498 cells is increased in response to 5 uM MPA, 1 uM verapamil and 2 uM tamoxifen, which are known to partially reverse the MDR phenotype in other resistant tumors. The effective concentration of MPA for MDR reversal is in clinically achievable concentration but one of verapamil is not. The chemosensitivity of Caki-2 cells does not change according to MDR modulating agents. .MPA is an effective MDR modulating agents to enhance the cytotoxicity of vinblastine in renal cell carcinoma cell line showing P-glycoprotein expression. It suggests that combination therapy of MPA and vinblastine is better than monotherapy with MPA or vinblastine alone.
