The gray vibrissae of Korean males(n =189) between 15 and 75 years old and females(n =111) between-15 and 74 years old who visited the department of otorhinolaryngology, Konkuk university Chungju hospital during 1996 to 1998, were counted for the purpose of estimating approximate age range in individuals of unknown age . The lowest age appearing gray hairs in both sexes was 15-year-old. The Pearson's correlation coefficient in both sexes was 0.490 (p<0.01). The age appearing gray vibrissae in females was slightly earlier than that of males, however, the differences between right and left sides of nasal cavity were insignificant. This method of counting gray vibrissae would be useful to estimate age range in personal identification together with other methods available until now.

PURPOSE: Extracorporeal shock wave lithotripsy (ESWL) is a first-line treatment for pediatric urinary stone disease. We aimed to determine the factors affecting the outcome of ESWL for unilateral urinary stones in children. MATERIALS AND METHODS: A total of 81 pediatric patients aged 0 to 16 years with urinary stones treated by ESWL from January 1995 through May 2012 were retrospectively reviewed. All patients were required to have unilateral urinary stone disease. Children who underwent other surgical procedures before ESWL were excluded. Outcomes evaluated after ESWL were the stone-free rate at 3 months after ESWL, success within a single session, and success within three sessions. Factors affecting the success within three sessions were also analyzed. RESULTS: The final analysis was for 42 boys and 22 girls (mean age, 9.2+/-5.2 years). Of these 64 patients, 58 (90.6%) were treated by ESWL without other surgical procedures and 54 (84.4%) were successfully treated within three ESWL sessions. In the multivariate analysis, multiplicity (odds ratio [OR], 0.080; 95% confidence interval [CI], 0.012 to 0.534; p=0.009) and large stone size (>10 mm; OR, 0.112; 95% CI, 0.018 to 0.707; p=0.020) were significant factors that decreased the success rate within three ESWL sessions. CONCLUSIONS: Most of the pediatric urinary stone patients in our study (90.6%) were successfully treated by ESWL alone without additional procedures. If a child has a large urinary stone (>10 mm) or multiplicity, clinicians should consider that several ESWL sessions might be needed for successful stone fragmentation.

BACKGROUND AND OBJECTIVES: Squamous cell carcinoma of thyroid is uncommon and accounts for less than 1% of all primary thyroid malignancies. Clinical features mimic the natural course of anaplastic carcinoma. This study reviewed the clinical course of six cases of primary squamous cell carcinoma of thyroid. SUBJECTS AND METHOD: We diagnosed six cases of primary squamous cell carcinoma of thyroid diagnosed from 1999 to 2006 at the College of Medicine Department of Pathology. Clinical data, treatment modality, and pathologic test results from medical records were retrospectively analyzed. RESULTS: We found five women and one man (with the mean age of 52.1 years) with squamous cell carcinoma of thyroid. The main presenting features were abruptly enlarging neck swelling and obstructive symptom. Pre-operative needle aspiration biopsy revealed papillary carcinoma in five cases. Only one patient was diagnosed as squamous cell carcinoma through pre-operative needle aspiration biopsy. Three patients had massive adjacent organ invasion, and four patients had lymph node metastasis according to the pathology review. There were no cases of distant metastasis at the time of treatment. All patients received surgery and adjuvant therapy (radiation therapy, chemotherapy, radioiodine therapy). Three patients are still alive with a mean follow up period of 47.3 months (range, 44-49 months). The other three patients died within one year post-operatively. CONCLUSION: Primary squamous cell carcinoma of thyroid should be considered in patients diagnosed with papillary carcinoma and who exhibit aggressive clinical behavior. Complete tumor resection and radiotherapy should be performed if thyroid squamous cell carcinoma is confirmed.

PURPOSE: We investigated the efficacy of transurethral injection of Macroplastique bulking agent (Uroplasty) for male stress urinary incontinence (SUI) after prostate surgery. MATERIALS AND METHODS: This retrospective review included men with SUI treated by transurethral injection for symptoms resulting from prostate surgery. Patients were evaluated at 1 month and 6 months after injection by determining the number of pads used per day and changes in incontinence symptoms. Treatment success was defined as use of 1 pad or fewer per day combined with subjective symptom improvement. RESULTS: The study population comprised 30 men with a mean age of 66.1+/-5.3 years. Of the 30 patients, 24 (80.0%) underwent prostate cancer surgery and the remaining 6 (20.0%) underwent surgery for benign prostatic hyperplasia. The preinjection pad number was 2.9+/-1.9 pads per day. After injection treatment, the mean follow-up period was 9.3+/-12.7 months and the success rate was 43% (13/30) at 1 month and 32% (6/19) at 6 months. Injection was more likely to result in a successful outcome in patients with no preinjection radiation treatment history and higher abdominal leak point pressure (ALPP) than in those with a previous history of radiation treatment and lower ALPP, although this result was not statistically significant. Acute urinary retention occurred in 5 patients (17%). CONCLUSIONS: Transurethral Macroplastique injection treatment is a relatively non-invasive treatment method for male SUI with a success rate of 43% at 1 month and 32% at 6 months. Patients with a higher ALPP and no previous history of radiation therapy may experience better treatment outcomes.

Febrile neutropenia (FN) is the major toxicity of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen in the treatment of diffuse large B-cell lymphoma (DLBCL). The prediction of neutropenia and FN is mandatory to continue the planned R-CHOP therapy resulting in successful anti-cancer treatment. The clinical features and patterns of neutropenia and FN from 181 DLBCL patients treated with R-CHOP were analyzed retrospectively. Sixty percent (60.2%) of patients experienced at least one episode of grade 4 neutropenia. Among them, 42.2% of episodes progressed to FN. Forty-eight percent (48.8%) of patients with FN was experienced their first FN during the first cycle of R-CHOP. All those patients never experienced FN again during the rest cycles of R-CHOP. Female, higher stage, international prognostic index (IPI), age > or =65 yr, comorbidities, bone marrow involvement, and baseline serum albumin < or =3.5 mg/dL were significant risk factors for FN by univariate analysis. Among these variables, comorbidities (P=0.009), bone marrow involvement (P=0.006), and female gender (P=0.024) were independent risk factors for FN based on multivariate analysis. On observing the patterns of neutropenia and FN, primary prophylaxis of granulocyte colony-stimulating factor (G-CSF) and antibiotics should be considered particularly in female patients, patients with comorbidities, or when there is bone marrow involvement of disease.

PURPOSE: To compare the perioperative outcomes of laparoscopic partial nephrectomy (LPN) and robotic partial nephrectomy (RPN) for moderately or highly complex tumors (RENAL nephrometry score> or =7). MATERIALS AND METHODS: A retrospective analysis was performed for 127 consecutive patients who underwent either LPN (n=38) or RPN (n=89) between 2007 and 2013. Perioperative outcomes were compared. RESULTS: There were no significant differences between the two groups with respect to patient gender, laterality, RENAL nephrometry score, or body mass index. The RPN group had a slightly higher RENAL nephrometry score (7.8 vs. 7.5, p=0.061) and larger tumor size (3.0 cm vs. 2.5 cm, p=0.044) but had a lower Charlson comorbidity index (3.7 vs. 4.4, p=0.017) than did the LPN group. There were no significant differences with respect to warm ischemia time, estimated blood loss, intraoperative complications, or operative time. Only one patient who underwent LPN had a positive surgical margin. There were statistically significant differences in surgical marginal width between the LPN and RPN groups (0.6 cm vs. 0.4 cm, p=0.001). No significant differences in postoperative complications were found between the two groups. Owing to potential baseline differences between the two groups, we performed a propensity-based matching analysis, in which differences in surgical margin width between the LPN and RPN groups remained statistically significant (0.6 cm vs. 0.4 cm, p=0.029). CONCLUSIONS: RPN provides perioperative outcomes comparable to those of LPN and has the advantage of healthy parenchymal preservation for complex renal tumors (RENAL score> or =7).

PURPOSE: To evaluate the oncologic outcomes and postoperative complications of high-intensity focused ultrasound (HIFU) as a salvage therapy after external-beam radiotherapy (EBRT) failure in patients with prostate cancer. MATERIALS AND METHODS: Between February 2002 and August 2010, we retrospectively reviewed the medical records of all patients who underwent salvage HIFU for transrectal ultrasound-guided, biopsy-proven locally recurred prostate cancer after EBRT failure (by ASTRO definition: prostate-specific antigen [PSA] failure after three consecutive PSA increases after a nadir, with the date of failure as the point halfway between the nadir date and the first increase or any increase great enough to provoke initiation of therapy). All patients underwent prostate magnetic resonance imaging and bone scintigraphy and had no evidence of distant metastasis. Biochemical recurrence (BCR) was defined according to the Stuttgart definition (PSA nadir plus 1.2 ng/mL). RESULTS: A total of 13 patients with a median age of 68 years (range, 60-76 years) were included. The median pre-EBRT PSA was 21.12 ng/mL, the pre-HIFU PSA was 4.63 ng/mL, and the period of salvage HIFU after EBRT was 32.7 months. The median follow-up after salvage HIFU was 44.5 months. The overall BCR-free rate was 53.8%. In the univariate analysis, predictive factors for BCR after salvage HIFU were higher pre-EBRT PSA (p=0.037), pre-HIFU PSA (p=0.015), and short time to nadir (p=0.036). In the multivariate analysis, there were no significant predictive factors for BCR. The complication rate requiring intervention was 38.5%. CONCLUSIONS: Salvage HIFU for prostate cancer provides effective oncologic outcomes for local recurrence after EBRT failure. However, salvage HIFU had a relatively high rate of complications.

Doxylamine is common over-the-counter sleep preparations & frequently involved in overdoses. The clinical course is dominated by the anticholinergic effects, including central nervous system & autonomic effects. We report 4 cases of suicide attempts in adults where ingestion of the doxylamines were complicated by rhabdomyolysis. They ingested doxylamines variable amount & were carried to emergency department. They complained gastrointestinal or central nervous system symptoms. Gastric lavages & administrations of activated charcoal were done. Creatine phosphok inase levels were normal or markedly elevated on arrival, but peaked several days later. Serum creatinine levels were normal. 99mTc-MDP bone scans were showed increased muscle labelling at the regions of muscle injury. They were treated with hydration, urine alkalinization, & supportive measures in hospital. On considering cause of rhabdomyolysis, our patients did not show any evidence of viral illness or coingestion of other potential myopathic toxins to support a secondary cause of rhabdomyolysis. The mechanism of rhabdomyolysis in cases of doxylamine overdose seems to be a direct toxic effect of the drug on striated muscle, but the exact mechanism is not clear. In all cases where such overdoses are suspected, consideration should be given to obtaining a urinalysis & a creatine phosphokinase level on arrival & creatine phosphokinase levels are carefully followed. Primary detoxication included gastric lavage & administration of activated charcoal. The patient's urine output & renal function should be closely monitored.

A 56-year-old male presented with resting dyspnea and chest discomfort for several years. During transthoracic and transesophageal echocardiography, a spontaneously healed membranous type ventricular septal defect (VSD) with malaligned interventricular septal wall, aneurysmal changes, a subaortic ridge and a double-chambered right ventricle (DCRV) was observed. When combined with DCRV, VSD with malalignment between the outlet and trabecular septa was associated with tetralogy of Fallot. The subaortic ridge was due to turbulent flow caused by the malalignment-type VSD. The VSD with malaligned interventricular septal wall can be developed after aneurismal changes of a perimembranous VSD. We report here in the unusual case of a 56-year-old patient who had a pathology complex comprising DCRV, subaortic ridge, spontaneously healed membranous type VSD with malaligned interventricular septal wall, and survived with surgical treatment.

This study aimed to identify the risk factors associated with acute hepatitis A virus (HAV) infection in the Korean population. Participants were recruited from five referral hospitals across the country in 2007 and from 11 hospitals in 2009. Patients with positive anti-HAV IgM antibody tests became the case group, while patients treated for non-contagious diseases at the same hospitals were recruited as controls. A total of 222 and 548 case-control pairs were studied in the 2007 and 2009 surveys, respectively. Data from the surveys were analyzed jointly. In a multivariate analysis, sharing the household with HAV-infected family members (OR, 6.32; 95% CI, 1.4-29.6), contact with other HAV-infected individuals (OR, 4.73; 95% CI, 2.4-9.4), overseas travel in 2007 (OR, 19.93; 95% CI, 2.3-174.4), consumption of raw shellfish (OR, 2.51; 95% CI, 1.8-3.5), drinking bottled water (OR, 1.64; 95% CI, 1.3-8.4), and occupation that involve handling food (OR, 3.30; 95% CI, 1.3-8.4) increased the risk of HAV infection. Avoiding contact with HAV-infected individuals and avoiding raw foods eating could help minimize the risk of hepatitis A infection. Immunization must be beneficial to individuals who handle food ingredients occupationally or travel overseas to HAV-endemic areas.
