The article presents a case study of a 38-year-old man who had developed hair transplantation-induced trichorrhexis nodosa. The man had demonstrated Norwood-Hamilton Class IVa male pattern baldness during hair transplantation in 2008. Histopathological test of scalp biopsy revealed a fibrous tract around the transplanted follicle. The article discusses how trichorrhexis nodosa develops and the causes of it.

The article presents a case study of a 60-year-old woman who was referred to a dermatologic clinic for the treatment of a pigmented, ulcerative mass in the melolabial sulcus. Histopathologic examination showed basal cell carcinoma (BCC) and the lesion was removed with the two-stage Mohs micrographic surgery. The study indicated that local skin flaps are preferred for melolabial fold repairs, however, classic local skin flaps and skin grafts often fail to achieve acceptable aesthetic outcomes.

BACKGROUND Palmar hyperhidrosis is characterized by excessive sweating on the palm, and among the various treatment modalities, tap water iontophoresis has been widely used. OBJECTIVE The objective of this study was to assess the effect of a new “dry-type” iontophoretic device that was locally manufactured and did not use tap water to control sweating. METHODS Ten subjects with palmar hyperhidrosis were enrolled in this study. To be treated the patients were instructed that they only have to grasp the device. Only one palm was treated for 2 weeks, and then the treatment was discontinued the following next 2 weeks. The other palm was not treated as a control. At the end of second week, biopsy specimens were obtained from untreated and treated palm, respectively, and examined histologically. RESULTS Nine of 10 patients were satisfied with this therapy reducing their sweat outputs from 33% to 51% of baseline at the end of 2 weeks' treatment, and after 2 weeks of discontinuation of treatment sweat productions returned to near baseline. The pathologic examinations showed some occlusions and destruction of intraepithelial eccrine ducts only in the treated palm. CONCLUSION We suggest that dry-type iontophoresis could reduce palmar sweating more conveniently than other conventional methods. [ABSTRACT FROM AUTHOR]

BACKGROUND A solution of 3% hydrogen peroxide is one of the most widely used antiseptics to decrease bacterial colonization. OBJECTIVE We performed this study to evaluate influence of 3% hydrogen peroxide on the survival rate of hair grafts. METHODS We designed two templates on both frontoparietal recesses of five patients with male pattern alopecia. Follicular units containing single hairs were obtained from occiput. We grafted approximately 50 follicular units on each template. The gauze with normal saline was applied on the left template and the gauze with 3% hydrogen peroxide on the right template for 5 minutes. This procedure was repeated four times at 30-minute intervals. The number of surviving hairs of each template was counted 3 and 10 months after hair transplantation. RESULTS There was no statistically significant difference in the mean survival rate of the grafts between hydrogen peroxide and normal saline 3 and 10 months after transplantation (Mann–Whitney test, p>.05). CONCLUSION We think surgical wound care with 3% hydrogen peroxide during hair restoration surgery does not affect the survival rate of hair grafts when compared with normal saline. We also need further evaluation with larger participants to overcome small sample size and to gather other information. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 22-year-old woman with history of hair loss for three years on her left temporal scalp. It states that the patient was diagnosed with temporal triangular alopecia (TTA) and undergo hair transplantation. It mentions that using Kyungpook National University (KNU) hair transplanter, 987 follicular units were transplanted.
