Osmidrosis is a symptom of foul odor at the axillae due to bacterial decomposition in apocrine sweat gland. It usually developed at puberty or adolescence and cause ruined clothing and negative social life. Complete removal of sweat gland from axillae is an essential of treatment. Various methods of surgical treatment were applied for osmidrosis axillae but nobody can easily obtain perfect result and escape from many surgical complications such as bleeding, skin necrosis, scar contraction and recurrence 4).Recently author tried new non-surgical method for removal of sweat gland with excellent results, and introduce it with literature.

OBJECTIVE: Epidural venous varicosity (congestion of the epidural vein) is rarely introduced as an influential factor of clinical symptoms. However, there are several studies suggesting that epidural venous varicosity results in neurologic symptoms. We would like to highlight evidence that epidural venous varicosity results in neurologic symptoms and the relation between epidural venous varicosity and neural structure observed during the surgery. Based on our experiences, we also propose a new classification of epidural venous varicosity. METHODS: 29 patients with symptomatic lumbar stenosis received microsurgical decompression via partial hemilaminectomy. The authors retrospectively reviewed all recorded intraoperative pictures and categorized patterns of venous varicosities with relationship to neural structures. RESULTS: Type A is conditions in which epidural veins are dilated but located parallel to the nerve root on the lateral side of the nerve root and thus do not compress the nerve root. Type B is conditions in which varices are located on the anterior lateral side of the nerve root to compress the nerve root. Type C is conditions in which varices are encircled around the nerve root and compressing the nerve root. CONCLUSION: Epidural venous varicosity is observed in most lumbar stenosis patients with clinical symptoms. Of the types, the types of epidural venous varicosity compressing nerve structures were Type B and Type C. All epidural venous varicosities were removed regardless of classification during operations. Most patients showed relief in clinical symptoms after the operation. We thought to epidural venous varicosity as a factor that causes clinical symptoms of lumbar stenosis.

PURPOSE: Compound tissue defects remain a challenge to reconstructive surgeons. The objective of this study was to introduce examples of successful reconstruction of compound defects of the head and neck and upper and lower limbs, using chimeric flaps based on the subscapular vascular system. METHODS: We report 19 reconstruction cases using chimeric flaps based on the subscapular vascular system. The scapular flap, scapular fascia, scapular bone, parascapular flap, latissimus dorsi, latissimus dorsi perforator flap, latissimus dorsi myocutaneous perforator flap, serratus anterior, serratus anterior fascia, and rib bone were used as components for chimeric flaps. 12 cases had defects of the upper limb, three in the lower limb, three in the head and neck area, and one case had a defect of the thoracoabdominal wall. RESULTS: Defect sizes ranged from 6x8cm to 20x22 cm. The component used most often for skin coverage was the latissimus dorsi perforator flap; for soft tissue bulk, the latissimus dorsi; for fascia coverage, the serratus anterior fascia flap; and for bone reconstruction, the scapular bone flap respectively. In all cases reconstruction was done successfully without additional operative procedures or flap necrosis. CONCLUSION: Because it is fairly easy to employ vascular pedicles of sufficient length and diameter, enabling the use of diverse types of tissue with various shapes and sizes, the use of chimeric flaps based on the subscapular vascular system allows one-stage reconstruction tailored to the characteristics of the defect area.

PURPOSE: To investigate the clinical significance of the internal lens signal measured using dual Scheimpflug anterior segment analyzer (Galilei(TM), Ziemer, Switzerland) in patients receiving cataract surgery. METHODS: The present study included 151 eyes of 148 patients who received surgery for senile cataracts from February 2012 to January 2013. Preoperative internal lens signals were measured preoperatively. The depth of anterior chamber and anterior angles were measured using dual Scheimpflug anterior segment analyzer preoperatively and 1 month postoperatively. Preoperative and postoperative best-corrected visual acuities (BCVAs) were measured. The relationships between preoperative internal lens signal and the changes in BCVA or anterior angles were evaluated. RESULTS: Internal lens signal and preoperative BCVA (log MAR) or preoperative anterior chamber depth were highly correlated (r = 0.287, p = 0.001 and r = -0.271, p = 0.004, respectively). Anterior angles increased 1 month after surgery compared with the preoperative values (p < 0.001). The amount of change between preoperative and postoperative anterior angles correlated with preoperative anterior angles (p < 0.001). However, no statistically significant correlation was observed between internal lens signal and preoperative anterior angles or postoperative BCVA. Internal lens signal correlated with changes in postoperative anterior angles (p < 0.001). CONCLUSIONS: Internal lens signal correlated with preoperative visual acuity and may help evaluate the cataract severity quantitatively and objectively. Internal lens signal may aid in understanding the structure of anterior segments by predicting the lens volume. Knowing the effect of visual impairment due to cataracts and predicting visual improvement after cataract surgery is necessary.

Background:
and Purpose: The expression of the 18-kDA mitochondrial translocator protein (TSPO) in the brain is an attractive target to study neuroinflammation. However, the binding properties of TSPO ligands are reportedly dependent on genetic polymorphism of the TSPO gene (rs6971). The objective of this study is to investigate the rs6971 gene polymorphism in the Korean population.
Methods:
We performed genetic testing on 109 subjects including patients with mild cognitive impairment, Alzheimer’s disease (AD) dementia, non-AD dementia, and cognitively unimpaired participants. Magnetic resonance imaging scans and detailed neuropsychological tests were also performed, and 29 participants underwent 18 F-DPA714 PET scans. Exon 4 of the TSPO gene containing the polymorphism rs6971 (Ala or Thr at position 147) was polymerase chain reaction amplified and sequenced using the Sanger method. The identified rs6971 genotype codes (C/C, C/T, or T/T) of the TSPO protein generated high-, mixed-, or lowaffinity binding phenotypes (HABs, MABs, and LABs), respectively.
Results:
We found that 96.3% of the study subjects were HAB (105 out of 109 subjects), and 3.7% of the subjects were MAB (4 out of 109 subjects). 18 F-DPA-714 PET scans showed nonspecific binding to the thalamus and brainstem, and increased tracer uptake throughout the cortex in cognitively impaired patients. The participant with the MAB polymorphism had a higher DPA714 signal throughout the cortex.
Conclusions
The majority of Koreans are HAB (approx. 96%). Therefore, the polymorphism of the rs6971 gene would have a smaller impact on the availability of second-generation TSPO PET tracers.

BACKGROUND: Autologous or implant-based breast reconstruction after nipple-sparing mastectomy is increasingly preferred worldwide as a breast cancer treatment option. However, postoperative nipple-areola complex (NAC) necrosis is the most significant complication of nipple-sparing mastectomy. The purpose of our study was to identify the risk factors for NAC necrosis, and to describe the use of our skin-banking technique as a solution. METHODS: We reviewed cases of immediate autologous breast reconstruction after nipple-sparing mastectomy at our institution between June 2005 and January 2014. The patients' data were reviewed and the risk of NAC necrosis was analyzed based on correlations between patient variables and NAC necrosis. Moreover, data pertaining to five high-risk patients who underwent the donor skin-banking procedure were included in the analysis. RESULTS: Eighty-five patients underwent immediate autologous breast reconstruction after nipple-sparing mastectomy during the study period. Partial or total NAC necrosis occurred in 36 patients (43.4%). Univariate analysis and binary regression modeling found that body mass index, smoking history, radiation therapy, and mastectomy volume were significantly associated with NAC necrosis. Of the 36 cases of NAC necrosis, 31 were resolved with dressing changes, debridement, or skin grafting. The other five high-risk patients underwent our prophylactic skin-banking technique during breast reconstruction surgery. CONCLUSIONS: NAC necrosis is common in patients with multiple risk factors. The use of the skin-banking technique in immediate autologous breast reconstruction is an attractive option for high-risk patients. Banked skin can be used in such cases without requiring additional donor tissue, with good results in terms of aesthetic and reconstructive outcomes.

PURPOSE: Because of difficulty of obtaining metaphase cells from tumor specimens, there are only a few cytogenetic studies in nasal NK/T-cell lymphomas, and so far no consistent specific chromosomal abnormalities have been described. In this study, we have used degenerate oligonucleotide primed PCR (DOP-PCR) and comparative genomic hybridization (CGH) to deter mine chromosomal alterations from 6 nasal NK/T-cell lymphoma tissues dissected from formalin- fixed paraffin-embedded slide sections. MATERIALS AND METHODS: For the isolation of tumor DNA, four 7-micrometer-thick tissue sections from each sample were dewaxed and rehydrated, and areas of high tumor cell content (more than 60%) were dissected and pooled into a tube. Normal DNA was prepared from the peripheral blood of a healthy volunteer. Tumor DNA was labeled with biotin-16-dUTP by DOP-PCR and normal DNA was labeled with digoxigenin-dUTP using a nick translation kit. In CGH, equal amounts of differently labeled DNA from the tumors and normal reference DNA were hybridized simul taneously to normal metaphase chromosomes. They were visualized by different fluordegrees Chromes, and the signal intensities were quantitated separately as gray levels for each chromosome. The over- and underrepresented DNA segments were determined by computation of image ratios and average ratio profiles. RESULTS: Our results show that gains of DNA copy number were more prevalence than DNA losses. The most commonly observed gains were mapped to chromosomal regions of 1p32.2 ter,19 and 20 in 4 of 6 cases (67%). The other frequent gains were found on chromosomes 12q in 3 of 6 cases. The most frequent loss was detected on 6q in 4 of 6 cases(67%), and less fre quently observed on 13q21.1 q34 and 13q14 q34. CONCLUSION: These genomic changes found in specific chromosomal regions are likely to harbor genes of importance in nasal NK/T-cell lymphomagenesis, therefore such cytogenetic mapping of genomic imbalance may be of value for further molecular delineation of NK/T-cell lymphoma.

Slipped capital femoral epiphysis (SCFE) is the most common orthopedic hip disorder occuring in adolescence. In this condition, the femoral head (epiphysis) displaces, or slips on the femoral neck through the region of the growth plate. This condition can occur only before the epiphyseal plate closes. The exact etiology is unknown, although it has been associated with obesity, hanical abnormalities, physeal abnormalities, endocrine disturbances (hypothyroidism, growth hormone deficiency, hypogonadism). Interestingly, SCFE was observed in growth hormone deficiency and in patients treated with growth hormone. We report a case of an adolescent male with glycogen storage disease Ia and growth hormone deficiency who developed SCFE during treatment with recombinant human growth hormone. A 17-year-old male was admitted for pain of left hip which was exacerbated by walking 15 days ago. He was diagnosed glycogen storage disease Ia and growh hormone deficiency 2 years ago and treated growth hormone therapy with recombinant human growth hormone at the dose of 2 unit/day. The diagnosis of SCFE was confirmed radiologically. From the time of admission, he received skin traction on the left hip joint and stopped to inject growth hormone and treated surgically with internal fixation of the epiphysis with use of 3-cannulated screw. The patient is followed at out-patient clinic without postoperative complication.

Adeno-associated virus (AAV) and human papillomavirus (HPV) DNAs were found in abnormal quality semen, early abortus and female genital tissues. It was suggested that they might cause male infertility and miscarriages. This study was performed to determine the detection rate of these viruses in the semen and to assess the relationship between the presence of virus and male factor infertility and recurrent miscarriages. Sixty-three of 99 recruited male were included in this study according to the completeness of follow-up and the sample availability. Fourteen male with normal reproductive capacity were allocated to control group, 15 male with abnormal results in semen analysis were grouped as male factor infertility (MF) group, and 34 male whose spouses have had history of repeated spontaneous abortions were designated as repeated miscarriage (RM) group. AAV and HPV were detected in semen by polymerase chain reaction. The detection rate of AAV in the MF infertility group and RM group was 60.0% and 50.0%, respectively, while 14.3% in the control group (p < 0.05). However, the differences in the detection rate of HPV were not statistically significant among groups. These results suggest that AAV could be related to repeated miscarriages and male infertility.
