Sensitive skin evaluation in the Japanese population

Sensitive skin syndrome was first described in 1977; however, no robust study has been carried out to evaluate its prevalence in Japan. A national representative sample of the Japanese population over the age of 18 years was taken. Individuals were questioned by telephone and selected according to the quota method. When asked “Do you have a sensitive skin?”, 52.84% of men and 55.98% of women answered “rather sensitive” or “very sensitive”. There was no significant difference (P = 0.22) between the two sexes. The non‐response rate among respondents was zero, suggesting that the term “sensitive skin” held a meaning for the majority of the population. Concerning questions about the onset of a rash, tingling or irritation in the presence of various factors, such as emotional issues, cold, heat, sun, dry air, air‐conditioning, water, air pollution and temperature variations, respondents with rather sensitive or very sensitive skin responded “yes” more often than others: approximately three‐times more often for water (18.97%/6.15%), air pollution (39.29%/12.45%) and warm climatic conditions (29.74%/9.8%). To our knowledge, this epidemiological study is the first to focus on sensitive skin among Japanese people of this century. It is of particular interest for two reasons: (i) it was conducted on a representative sample of the Japanese population; and (ii) the methodology used was identical to that used for sensitive skin assessment studies conducted in Europe and the USA, making it possible to draw certain comparisons.     

Preparation and development of solid phase radioimmunoassay system for determination of cortisol

The goal of this article was oriented to prepare stable polystyrene coated tubes for direct radioimmunoassay (RIA) of human cortisol. Coating process was performed using rabbit polyclonal antisera specific for cortisol. The stability study showed that these tubes could be stored for up to one year at 4ºC without any appreciable reduction in their binding. Labeling of cortisol was carried out using chloramin-T method and the ¹²⁵I-cortisol tracer was purified using HPLC column. Preparation of polyclonal antibodies (anti-cortisol) was carried out in host rabbit animals against cortisol-21-hemisuccinate:Bovine serum albumin conjugate. The statistical analysis revealed good correlations between the results from the present study and the commercial IZOTOP RIA kit. The local may be extremely helpful in diagnosis and proper management of adrenal cortex disorders.

肝郁痰凝型乳腺癌的钼靶X线表现及病理分析

目的：研究肝郁痰凝型乳腺癌的钼靶X线影像特点，探讨其病理基础。方法：观察41例中医证型为肝郁痰凝型、术后病理检查结果为乳腺癌患者的钼靶X线影像表现，对其病理学基础进行分析。结果：41例肝郁痰凝型乳腺癌中，乳腺类型以致密型及混合型居多（占78％）。异常血管征及透环征出现频率较高（占80％以上）。腋淋巴结转移出现频率偏低（占12％）。结论：（1）肝郁痰凝型乳腺癌患者，乳腺密度多偏高，可能与较多发生在绝经期前有关。（2）肿瘤周围透亮环征象及异常血管征象出现频率较高，表明此型患者肿块周围脂肪代谢异常较为普遍及血管生长刺激因子分泌较多。（3）腋窝淋巴结转移者所占比例较小，可能是由于此类患者多属于癌变早、中期，相对气血不足或脾肾虚弱等正虚表现不明显。

Antibodies to diphtheria, tetanus and pertussis in infants before and after immunization with DTP (Triple Antigen) vaccine

Objective : To determine antibody levels to the Australian manufactured combined diphtheria, tetanus and pertussis (DTP) vaccine (Triple Antigen, CSL Ltd) in infante before and after their primary immunization course.
Methodology : Serosurvey (antibody prevalence study) in two groups: infants aged 5-9 weeks who had not received any immunizations ( n = 25), and infants aged 7-10 months who had received two ( n = 25) or three immunizations ( n = 57) with DTP, sampled from infants attending the Royal Children's Hospital, Melbourne, either as inpatients or outpatients between February and April 1993. The immunization history for each infant was determined from hospital records, the parent-held child health record, or the local council or family doctor who immunized the infant.
Results : Enzyme immunoassay (EIA) of antibodies to diphtheria and tetanus showed all infants to have adequate protective levels after two or three vaccinations (£0.01 IU/mL). All subjects who had received all three DTP vaccinations had detectable antibody to at least one pertussis antigen. Antibodies to the pertussis antigens filamentous haemagglutinin and pertussigen (pertussis toxin) were comparable to levels determined for whole cell pertussis vaccines used elsewhere in the world. EIA-determined antibodies to pertussis agglutinogen type 2 and agglutinogen type 3 showed substantially higher geometric mean titres when results for pre-immunization and post-immunization subjects were compared.
Conclusions : These data show that the Australian manufactured DTP vaccine has immunogenic properties similar to those of vaccines used elsewhere, and that antibody concentrations following immunization are at levels consistent with efficacy.     

Nuchal cord: impact of umbilical artery Doppler indices on intrapartum and neonatal outcomes: a prospective cohort study

Background/objective: The purpose of this study is to investigate the use of a more biologic parameter for evaluation of the effect of nuchal cord tightness; the study of blood flow in the umbilical arteries of nuchal cord using Doppler ultrasonography.

Methods: This prospective cohort study was conducted at Ain Shams University Maternity Hospital, Cairo, Egypt in the period between August 2015 and August 2017. Hundred primigravidas were recruited with nuchal cord diagnosed by Doppler ultrasonography; whereas the rest of the study population was included in the “Control group”. Doppler velocimetry study was then performed on a free-floating loop of the umbilical cord and Doppler indices were calculated. Both groups were followed up during labor: intrapartum events, mode of delivery, and neonatal outcome were recorded.

Results: Intrapartum fetal heart rate abnormalities were significantly more common in the nuchal cord group compared to the control group. The overall cardiotocography category was significantly more commonly reflecting abnormal fetal heart rate patterns in the nuchal cord group compared to the control group with 46.74% of the nuchal group patients falling within the “suspicious – pathological – need urgent intervention” categories. Intervention rate was significantly higher in the nuchal cord group than the control group (33.69 versus 21.84%). Moreover, incidence of intrapartum fetal heart rate abnormalities and intervention rate were significantly higher in the nuchal cord with abnormal Doppler subgroup compared to both nuchal cord with normal Doppler subgroup and the control group; with a calculated number needed to harm of 2.11.

Conclusions: In view of these results, it might be concluded that umbilical cord tightness affecting fetal hemodynamics (expressed by changes in umbilical artery Doppler) might be a determinate factor affecting the intrapartum course.
