Breast surgery is fully justified only in aesthetic perspectives. Although there are largely two areas in breast surgery, reconstruction and aesthetic, they frequently overlap each other. A reconstructed breast, therefore, should be aesthetically as natural as possible and similar to the contralateral one, even if this means reproducing some little defects. The authors present our experience of recent 6 years in breast reconstruction with an aesthetic eye and an artistic touch, and illustrate personal tips and technical adjustments: use of anatomical prostheses, autologous tissue transfer, axillary fold and nipple-areola complex reconstruction, including augmentation mammaplasty(implant, fat injection) and reduction mammaplasty. In 6 years, 178 cases of breast surgery were performed. Breast reconstruction(post-mastectomy, post burn deformity, congenital deformity etc) was 106 cases. There were 83 TRAM free flap cases, 10 Latissimus dorsi free flap cases. 7 cases using tissue expander and breast implant and 6 were fat graft cases. Number of breast augmentation was 35(25 submuscular, 10 subglandular). Breast reduction procedure was performed in 37 cases(13 periareolar, 8 vertical, 14 inferior pyramidal and 2 free nipple graft technique). The factors characterizing aesthetic results are profiles of breast(projection, inframammary fold location, superficial evenness, and ptosis), symmetry, axillary fold, areola, and nipple. In every procedure, we take account above factors, and results were satisfactory both surgically and aesthetically.

BACKGROUND/AIMS: The aim of this study was to investigate the role of psychosocial problems and their associations with rotating shift work in the development of functional gastrointestinal disorders. METHODS: In this cross-sectional observation study, survey was administered to nurses and nurse assistants in a referral hospital. In addition to demographic questions, subjects were asked to complete the Rome III Questionnaire, Pittsburgh Sleep Quality Index and Rome III Psychosocial Alarm Questionnaire. RESULTS: Responses from 301 subjects were assessed. The overall prevalence of irritable bowel syndrome (IBS) and functional dyspepsia (FD) were 15.0% and 19.6%, respectively. Psychosocial alarms were prevalent in the nursing personnel (74.8% with alarm presence and 23.3% with serious condition) and were more frequent among rotating shift workers (84.7% vs. 74.5% for alarm presence and 28.1% vs. 13.3% for serious condition). The prevalence of both IBS and FD significantly increased with psychosocial risk. An independent risk factor for IBS was serious psychosocial alarm (adjusted odds ratio [aOR], 10.75; 95% confidence interval (CI), 1.30-88.99; P = 0.028). Serious psychosocial alarm was an independent risk factor for FD (aOR, 7.84; 95% CI, 1.98-31.02; P = 0.003). Marriage (aOR 0.30; 95% CI, 0.09-0.93; P = 0.037) was associated with the decreased risk of FD. CONCLUSIONS: The high prevalence of psychosocial stress among nurses who work rotating shifts is associated with the development of functional gastrointestinal disorders.

BACKGROUND/AIMS: Hyperglycemia is associated with decreased 2-18[F]fluoro-2-deoxy-D-glucose (FDG) uptake by tumors assessed by positron emission tomography (PET). In this retrospective study we investigated a comparison of standardized uptake values (SUVs) in patients with primary colorectal cancers who either had diabetes mellitus (DM) or were otherwise healthy. METHODS: The medical records of 397 patients who were diagnosed with colorectal cancer and underwent PET-CT between January 2006 and December 2012 were analyzed. Eighty patients with DM and 317 patients without DM were included. Clinical characteristics were reviewed and maximal standardized uptake values (SUVmax) were calculated in the primary colorectal lesions. RESULTS: There was no significant difference between tumor SUVmax in DM patients (10.60+/-5.78) and those without DM (10.92+/-5.44). In addition, no significant difference was detected between tumor SUVmax in DM patients with glycated hemoglobin (HbA1c) levels <8% (10.34+/-5.17) and those with HbA1c levels > or =8% (10.61+/-7.27). The maximum size of the primary colorectal tumor was associated with SUVmax in a linear regression analysis. CONCLUSION: The results of this study showed that DM did not influence FDG uptake values in colorectal cancer patients regardless of glucose levels.

BACKGROUND: Cystic fibrosis is a chronic progressive autosomal recessive disorder caused by the CFTR gene mutations. It is quite common in Caucasians, but very rare in Asians. Sweat chloride test is known to be a screening test for the cystic fibrosis due to the fact that electrolyte levels in sweat are elevated in patients. In this study, sweat chloride levels in Korean population were measured and analyzed by using standardized pilocarpine iontophoresis sweat chloride test. METHODS: The sweat chloride test was performed in 47 patients referred to Yondong Severance Hospital from August, 2001 to April, 2007 and 41 healthy volunteers. The sweat chloride tests were conducted according to the CLSI C34-A2 guideline using pilocarpine iontophoresis method, and the chloride concentrations in sweat were measured by mercurimetric titration. RESULTS: Four patients showed sweat chloride concentrations higher than 60 mmol/L. Reference interval was calculated as 1.4-44.5 mmol/L by analysis of the results of healthy volunteers (n=41). Four patients who exhibited high sweat chloride levels, had characteristic clinical features of cystic fibrosis and their diagnoses were confirmed either by repeated sweat chloride test or genetic analysis. CONCLUSIONS: Standardized sweat chloride test can be utilized as a useful diagnostic tool for cystic fibrosis in Koreans. In cases of sweat chloride levels higher than 40 mmol/L, the test should be repeated for the possible diagnosis of cystic fibrosis. All the confirmed Korean cases of cystic fibrosis showed sweat chloride level above 60 mmol/L.

OBJECTIVE: For the effective retrieval of clinical information, the elaborate indexing is essential. Two major types of indexing are the human indexing and the automatic or machine indexing. Human indexing shows higher quality but is time consuming, labor-intensive and inconsistent in term assignment activity. METHODS: Using the Unified Medical Language System (UMLS) MetaMap program, we mapped the free text from the diagnosis section of radiology reports into UMLS concepts. To improve the precision of UMLS concept indexing by MetaMap, we evaluated the UMLS subset mapping and semantic type filtering methods, determining the best combination for improved precision. RESULTS: After calculating the candidates from subset combinations, we obtained more enhanced results by semantic-type filtering. CONCLUSION: The results may be improved for the complete automation of indexing process.

On the 12th day of abacavir treatment, a 39-year old HIV-infected male patient was admitted with fever, generalized rash, abdominal pain, and watery diarrhea that had persisted for five days. Results of blood tests indicated rapid progression of hepatitis and renal failure. The day after stopping anti-retroviral therapy, his fever subsided and his liver function began to normalize. He was clinically diagnosed with abacavir hypersensitivity and was found to carry the HLA-B*57:01 allele. This is the first reported case of abacavir hypersensitivity associated with the presence of the HLA-B*57:01 allele in Korea.

PURPOSE: According to surgical dogma, patients who are recovering from general anesthesia after abdominal surgery should begin with a clear liquid diet, progress to a full liquid diet and then to a soft diet before taking regular meals. We propose patient-controlled nutrition (PCN), which is a novel concept in postoperative nutrition after abdominal surgery. METHODS: A retrospective pilot study was conducted to evaluate the feasibility and effects of PCN. This study was carried out with a total of 179 consecutive patients who underwent a laparoscopic appendectomy between August 2014 and July 2016. In the PCN group, diet was advanced depending on the choice of the patients themselves; in the traditional group, diet was progressively advanced to a full liquid or soft diet and then a regular diet as tolerated. The primary endpoints were time to tolerance of regular diet and postoperative hospital stay. RESULTS: Time to tolerance of a regular diet (P < 0.001) and postoperative hospital stay (P < 0.001) showed statistically significant differences between the groups. Multivariate analysis using linear regression showed that the traditional nutrition pattern was the only factor associated with postoperative hospital stay (P < 0.001). Multivariate analysis using logistic regression showed that traditional nutrition was the only risk factor associated with prolonged postoperative hospital stay (≥3 days). CONCLUSION: After abdominal surgery, PCN may be a feasible and effective concept in postoperative nutrition. In our Early Recovery after Surgery program, our PCN concept may reduce the time to tolerance of a regular diet and shorten the postoperative hospital stay.
