BACKGROUND: Chlamydia trachomatis is most common sexually transmitted pathogen in the world, and a common cause of urethritis and cervicitis. Also it is common cause of preterm premature rupture of membranes and premature labor in pregnant women, and pneumonitis and conjunctivitis in neonate. A rapid and sensitive polymerase chain reaction(PCR)-based assay for detection of C. trachomatis is recently introduced. OBJECTIVES: We studied to determine whether a PCR assay is useful to detect Chlamydial infection in pregnant women. We also studied to compare its prevalence rate according to maternal age, trimester and parity, respectively. Study Design: Specimens were collected from 149 pregnant women by transcervical swab or endocervical lavage. If a specific band was detected in PCR assay, we considered as Chlamydial infection. RESULTS: In general, the positive bands were detected in the 45 of 149 pregnant women(30.2%). The positive bands were detected the 6 of 55(10.9%), 16 of 49(32.7%), and 23 of 45(51.1%) pregnant women in each trimester, respectively. Therefore, there was significantly increased according to the gestational age(p<0.05). However, there were not significantly different according to maternal age and parity(p> 0.05). CONCLUSION: We concluded that the PCR assay is a fast and useful test for the detection of C. trachomatis in transcevical cells from the pregnant women. This study suggested that Chlamydial infection seems to be increased according to the gestational age.

BACKGROUND: Although the pathogenesis of vitiligo isn't fully understood, a recent study demonstrates that oxidative stress plays an important role to induce vitiligo. Peroxiredoxin (Prx) is a novel peroxidase family to remove hydrogen peroxide using thioredoxin system, which is consisted of thioredoxin, thioredoxin reductase, and NADPH. OBJECTIVE: This study aimed to investigate the change of expression of Prx I to elucidate the role of oxidative stress in the pathogenesis of vitiligo. METHODS: Sample specimens were obtained from the lesional skin of vitiligo patients, and non-depigmented skin was obtained from the perilesional area as control samples. The skin samples were immediately frozen using liquid nitrogen, and then section samples were prepared to perform immunohistochemical staining with antibodies for Prx I. Some of the skin biopsy samples were used for primary culture of keratinocytes. Protein extracts from the expanded keratinocytes were prepared for Western blot analysis of Prx I. RESULTS: In vitiligo, the ubiquitous expression of Prx I in all layers of epidermis, which was also observed in the normal perilesional skin, was reduced in the depigmented lesion of vitiligo patients. The reduction of Prx I was remarkable from the lesions which were exposed to sunlight. Consistently, Prx I expression from the lesional keratinocytes were noticeably reduced in comparison with that from perilesional keratinocytes. CONCLUSION: Our results showing that Prx I is impaired in the epidermis of depigmented lesions of vitiligo patients suggest that oxidative stress is an important factor to induce vitiligo.

PURPOSE: Traditional transcutaneous incision and transconjunctival incision methods are commonly used in the lower blepharoplasty. The transconjunctival method leaves no visible scars nor does it change the shape of lower eyelid contour and the surgical technique is not difficult. However removal of excess baggy skin is not possible through this method. Therefore, the transconjunctival incision method is useful only for patients who still have normal elasticity of the lower eyelids and fat that is protruding only anterocaudally. The Author will introduce a technique, which complements the limitations of these two methods mentioned above. METHODS: The author combined the transconjunctival approach and lower blepharoplasty with only the excised skin flap method. This method does not go beyond the previous methods but does apply the advantages of them. RESULTS: From March 2007 to October 2010, this new technique was performed in a total of 62 patients. Fat was removed and repositioned through transconjunctival incision. Drooped skin was excised as in the traditional blepharoplasty but only the skin flap was elevated. This prevents post-operative complications such as ectropion, sclera show, and deformation of the shape of the lower eyelids or under-resection of fat. All patients were satisfied with the post-operative appearance. CONCLUSION: The author was able to get satisfactory results while avoiding complications of traditional transcutaneous technique with this combined technique of the transconjunctival approach and the lower blepharoplasty method of skin flaps only.
