  • Objectives : A safety issue on acupuncture and moxibustion treatment during pregnancy is as important as effectiveness. To establish a rationale and research strategy for future studies, a traditional literature review was performed to summarize how and for what conditions acupuncture and moxibustion treatment was given during pregnancy. Methods : An extensive traditional literature search for acupuncture and moxibustion treatment during pregnancy was conducted in texts on acupuncture and moxibustion, obstetrics and gynecology, and comprehensive medical texts. Treatment conditions, methods, and contraindications were summarized and tabulated. Results : Twenty-eight books were included in our review. Most frequent description of acupuncture and moxibustion treatment use during pregnancy was for difficult delivery including breech presentations; commonly used acupuncture points for difficult labor included LI4, SP6, BL67, BL60, KI6, ST30, SP12, LR4, LR3, PC6, CV3, CV14, KI13, and GB21, indicating that they may have to be avoided during pregnancy. Descriptions of other symptoms or conditions were sparse. For habitual abortion or recurrent miscarriage, moxibustion on GV4, BL23, CV3, KI8, and KI2 was indicated. A combination of LI4 and SP6, and CV4 were contraindicated during pregnancy consistently across the reviewed books. Conclusions : Our traditional literature review has shown that the use of acupuncture and moxibustion treatment during pregnancy has been limited. Given that more and more pregnant women are interested in safe and effective treatment, further research of acupuncture's safety and efficacy during pregnancy is urgently needed.

  • Preimplantation genetic diagnosis (PGD) is gradually widely used in prevention of gene diseases and chromosomal abnormalities. Much improvement has been achieved in biopsy technique and molecular diagnosis. Blastocyst biopsy can increase diagnostic accuracy and reduce allele dropout. It is cost-effective and currently plays an important role. Whole genome amplification permits subsequent individual detection of multiple gene loci and screening all 23 pairs of chromosomes. For PGD of chromosomal translocation, fluorescence $in-situ$ hybridization (FISH) is traditionally used, but with technical difficulty. Array comparative genomic hybridization (CGH) can detect translocation and 23 pairs of chromosomes that may replace FISH. Single nucleotide polymorphisms array with haplotyping can further distinguish between normal chromosomes and balanced translocation. PGD may shorten time to conceive and reduce miscarriage for patients with chromosomal translocation. PGD has a potential value for mitochondrial diseases. Preimplantation genetic haplotyping has been applied for unknown mutation sites of single gene disease. Preimplantation genetic screening (PGS) using limited FISH probes in the cleavage-stage embryo did not increase live birth rates for patients with advanced maternal age, unexplained recurrent abortions, and repeated implantation failure. Polar body and blastocyst biopsy may circumvent the problem of mosaicism. PGS using blastocyst biopsy and array CGH is encouraging and merit further studies. Cryopreservation of biopsied blastocysts instead of fresh transfer permits sufficient time for transportation and genetic analysis. Cryopreservation of embryos may avoid ovarian hyperstimulation syndrome and possible suboptimal endometrium.

  • Background: Anogenital warts (AGWs) are common results of sexually transmitted infection (STI). Human papillomavirus (HPV) types 6 and 11, which are non-oncogenic types, account for 90% of the clinical manifestations. Although the quadrivalent HPV vaccine has been launched, AGW remains prevalent in some countries and shows association with abnormal cervical cytology. Objectives: To study the prevalence of abnormal cervical cytology (low grade squamous intraepithelial lesions or worse; LSIL+) in immunocompetent Thai women newly presenting with external AGWs. Materials and Methods: Medical charts of all women attending Siriraj STI clinic during 2007-2011 were reviewed. Only women presenting with external AGWs who were not immunocompromised (pregnant, human immunodeficiency virus positive or being on immunosuppressant drugs) and had not been diagnosed with cervical cancer were included into the study. Multivariate analysis was used to determine the association between the characteristics of the patients and those of AGWs and LSIL+. Results: A total of 191 women were eligible, with a mean age of $27.0{\pm}8.9$ years; and a mean body mass index of $20.6{\pm}8.9kg/m^2$. Half of them finished university. The most common type of AGWs was exophytic (80.1%). The posterior fourchette appeared to be the most common affected site of the warts (31.9%), followed by labia minora (26.6%) and mons pubis (19.9%). The median number of lesions was 3 (range 1-20). Around 40% of them had recurrent warts within 6 months after completing the treatment. The prevalence of LSIL+ at the first visit was 16.3% (LSIL 12.6%, ASC-H 1.1%, HSIL 2.6%). After adjusting for age, parity and miscarriage, number of warts ${\geq}5$ was the only factor associated with LSIL+(aOR 2.65, 95%CI 1.11-6.29, p 0.027). Conclusions: LSIL+ is prevalent among immunocompetent Thai women presenting with external AGWs, especially those with multiple lesions.

  • Aim: To report long term outcomes of laser conization for high grade cervical intraepithelial neoplasia (CIN) in Thai women. Materials and Methods: A retrospective cohort study was conducted in patients undergoing laser conization due to abnormal cervical cytology suggesting neoplasia during 1989 to 1994 and having follow-up data until December 2010. Conization was performed under colposcopy using a 0.5-mm $CO_2$ laser beam with power density of $18,000-20,000watts/cm^2$, and the surgical base was vaporized using a low power defocused beam. The follow-up protocol included cervical cytology and colposcopy. Long term outcome measures were failure rate (persistence and recurrence), post-conization status of transformation zone, and obstetric outcomes. Results: Of 104 patients undergoing conization, 71 had therapeutic conization for high grade CIN and were followed up for a median time of 115 (range 12-260) months. There was one case of persistent and one of recurrent disease comprising a failure rate of 2.8%. The post treatment transformation zone was well visualized in 68.3% of 63 patients with an intact uterus. Sixteen patients achieved 25 pregnancies; none had second trimester miscarriage. The obstetric outcomes were unremarkable. Conclusions: Laser conization under colposcopic visualization for the treatment of high grade CIN in Thai women has a low failure rate of 2.8%. The post-conization transformation zone could not be evaluated completely in approximately 30% of cases; therefore the follow-up protocol should include both cytology and colposcopy. Obstetric outcomes are not adversely affected by this therapeutic procedure.

  • 목 적: 임신 전 $CD3^-/CD56^+/CD16^+$ 말초혈액 자연살해세포 (pbNK cell)의 분획과 세포용해 활성도를 정상군과 습관성 유산의 기왕력을 가진 환자군으로 나누어 비교, 분석하고 습관성 유산의 위험도를 제시할 수 있는 각각의 cut-off value를 설정하고자 하였다. 연구방법: 전향적 연구로서 습관성 유산의 기왕력이 있는 여성을 환자군 (n=35)으로 하였으며, 대조군으로 불임이나 습관성 유산의 기왕력이 없으며 정상아의 출산 경험이 있는 여성을 대조군 (n=15)으로 설정하였다. 유세포분석기를 이용하여 pbNK cell 분획 및 세포용해 활성도를 측정 후 그 결과를 비교 분석하였다. 결 과: pbNK cells의 분획은 습관성 유산 환자군에서 대조군에 비해 통계적으로 유의하게 높은 결과를 보였다($14.2{\pm}5.2$ vs. $9.4{\pm}3.7%$, p=0.002, 95% confidence interval [CI] 1.8~7.8). Receiver operating characteristic curve (ROC) 곡선을 이용하여 pbNK cell의 분획에 대한 cut-off values을 12.1%로 정하였을 때 습관성 유산의 위험도는 8.4배 증가하였다. pbNK cell의 K562 세포용해 활성도를 3가지 다른 Effector to Target (E:T) 비율 (50:1, 25:1, 12.5:1)을 사용하여 측정한 결과 각각의 경우에 있어 습관성 유산 환자군에서 대조군에 비해 통계적으로 유의하게 증가된 결과를 보였다 ($48.3{\pm}19.0$ vs. $31.3{\pm}11.9%$ in 50:1 ratio, p=0.002; $37.0{\pm}18.1$ vs. $20.2{\pm}9.2%$ in 25:1 ratio, p<0.001; $23.5{\pm}12.7$ vs. $12.4{\pm}7.3%$ in 12.5:1 ratio, p=0.001). ROC 곡선을 이용하여 각각 E:T 비율에서 세포용해 활성도의 cut-off values (43.1% in 50:1, 26.9% in 25:1, and 17.4% in 12.5:1)을 설정하여 분석한 결과 습관성 유산의 위험도는 각각 10.0배, 11.4배, 그리고 15.0배 증가된 결과를 보였다. 결 론: 원인이 분명하지 않은 습관성 유산 환자에서 pbNK cell의 분획과 세포용해 활성도를 측정하는 것은 면역학적 원인, 특히 동종면역 요인에 의한 습관성 유산의 유용한 진단 지표로 이용될 수 있을 것으로 사료된다. 향후 동종 면역반응에 의한 습관성 유산 환자에서 면역학적 원인의 치료 전, 후 pbNK cell의 분획과 세포용해 활성도를 측정, 비교하여 그 효과를 증명하는 연구가 필요할 것으로 생각된다.
