BACKGROUND: Little is known concerning hair diameter variation within the safe donor area for hair transplantation surgery. Thicker or thinner hair may be needed, depending on the recipient area, hairline design, and the purpose of surgery. METHODS: Twenty-seven patients (7 men and 20 women; mean age, 28 years; range, 20–47 years) were included in this study. The midoccipital point was used as the reference point on the horizontal plane at the upper border of the helical rim. The target area width was 15 cm (7.5 cm to the right and left of the reference point) and the height was 8 cm (2 cm above and 6 cm below the reference point). The study area was divided horizontally into 3 5-cm sections (A, B, C) and vertically into 4 2-cm sections (1–4), creating a total of 12 zones. Ten anagen hairs were randomly obtained from each zone and their diameters were measured. RESULTS: Hair diameter in the 4 vertical sections varied significantly, gradually decreasing from sections 1 (superior) to 4 (inferior) in all 3 horizontal sections (A, B, and C). CONCLUSIONS: Our results suggest that sections 1 and 2 of the occipital safe donor area would be useful for obtaining thicker hair, such as in procedures to treat male- and female-pattern hair loss, whereas hair from zones 3 and 4 could be useful for transplantation surgery requiring thinner hair, such as eyebrows, eyelashes, and female hairline correction. Our results may be clinically valuable for planning hair transplant surgery and choosing the optimal donor region.

It has been suggested that cortisol deficiency may be responsible for the cholestasis. Although congenital hypopituitarism was reported as a possible cause of neonatal cholestasis, congenital adrenal hyperplasia with neonatal cholestasis is a very rare report in the literature. We experienced a case presenting with neonatal cholestasis associated with congenital adrenal hyperplasia. This case provides a clinical evidence supporting the notion that cortisol has an important physiological role in bile acid synthesis and transport.

A yeast strain, designated as JAF-11 T , was isolated from flower ofPrunus mume Sieb. et Zucc. in Gwangyang, Republic of Korea. Phylogenetic analysis showed that strain JAF-11 T was closely related to Neodothiora populina CPC 39399 T with 2.07 % sequence divergence (12 nucleotide substitutions and three gaps in 581 nucleotides) in the D1/D2 domain of the large subunit (LSU) rRNA gene, and Rhizosphaera macrospora CBS 208.79 T with 4.66 % sequence divergence (25 nucleotide substitutions and five gaps in 535 nucleotides) in the internal transcribed spacer (ITS) region. Further analysis based on the concatenated sequen ces of the D1/D2 domain of the LSU rRNA gene and the ITS region confirmed that strain JAF-11 T was well-separated from Neodothiora populina CPC 39399 T . In addition to the phylo genetic differences, strain JAF-11 T was distinguished from its closest species, Neodothiora populina CPC 39399 T and Rhizosphaera macrospora CBS 208.79 T belonging to the family Dothioraceae by its phenotypic characteristics, such as assimilation of carbon sources. Hence, the name Neodothiora pruni sp. nov. is proposed with type strain JAF-11 T (KACC 48808 T ; MB 850034).

BACKGROUND: Infective endocarditis shows high surgical mortality and morbidity rates, especially for aortic endocarditis. This study attempts to investigate the clinical characteristics and operative results of isolated aortic endocarditis. MATERIAL AND METHOD: From July 1990 to May 2005, 25 patients with isolated aortic endocarditis (Group I, male : female=18 : 7, mean age 43.2+/-18.6 years) and 23 patients with isolated mitral endocarditis (Group II, male : female=10 : 13, mean age 43.2+/-17.1 years) underwent surgical treatment in our hospital. All the patients had native endocarditis and 7 patients showed a bicuspid aortic valve in Group I. Two patients had prosthetic valve endocarditis and one patientsdeveloped mitral endocarditis after a mitral valvuloplasty in Group II. Positive blood cultures were obtained from 11 (44.0%) patients in Group I, and 10 (43.3%) patients in Group II. The preoperative left ventricular ejection fraction for each group was 60.8+/-8.7% and 62.1+/-8.1% (p=0.945), respectively. There was moderate to severe aortic regurgitation in 18 patients and vegetations were detected in 17 patients in Group I. There was moderate to severe mitral regurgitation in 19 patients and vegetations were found in 18 patients in Group II. One patient had a ventricular septal defect and another patient underwent a Maze operation with microwaves due to atrial fibrillation. We performed echocardiography before discharge and each year during follow-up. The mean follow-up period was 37.2+/-23.5 (range 9~123) months. RESULT: Postoperative complications included three cases of low cardiac output in Group I and one case each of re-surgery because of bleeding and low cardiac output in Group II. One patient died from an intra-cranial hemorrhage on the first day after surgery in Group I, but there were no early deaths in Group II. The 1, 3-, and 5-year valve related event free rates were 92.0%, 88.0%, and 88.0% for Group I patients, and 91.3%, 76.0%, and 76.0% for Group II patients, respectively. The 1, 3-, and 5-year survival rates were 96.0%, 96.0%, and 96.0% for Group I patients, and 100%, 84.9%, and 84.9% for Group II patients, respectively. CONCLUSION: Acceptable surgical results and mid-term clinical results for aortic endocarditis were seen.

In order to increase inhaled corticosteroid (ICS) use and to reduce hospitalization, emergency department visits and ultimately the economic burden of asthma, "Korean Asthma Management Guideline for Adults 2007" was developed. To assess the guideline effects on physician's ICS prescription for asthma, we conducted segmented regression and multilevel logistic regression using National Health Insurance claims database of outpatient visits from 2003 to 2010. We set each quarter of a year as a time unit and compared ICS prescription between before and after guideline dissemination. A total of 624,309 quarterly visits for asthma was observed. The ICS prescription rate before and after guideline dissemination was 13.3% and 16.4% respectively (P < 0.001). In the segmented regression, there was no significant guideline effect on overall ICS prescription rate. In multilevel logistic regression analyses, the effect of guideline on overall ICS prescription was not significant (odds ratio, 1.03; 95% CI, 1.00-1.06). In subgroup analysis, ICS prescription increased in secondary care hospitals (odds ratio, 1.15; 95% CI, 1.02-1.30) and in general hospitals (odds ratio, 1.10; 95% CI, 1.04-1.16). However, in primary clinics, which covered 81.7% of asthma cases, there was no significant change (odds ratio, 0.98; 95% CI, 0.94-1.02). From the in-depth interview, we could identify that the reimbursement criteria of the Health Insurance Review and Assessment Service and patient's preference for oral drug were barriers for the ICS prescription. The domestic asthma clinical guideline have no significant effect on ICS prescription, especially in primary clinics.

PURPOSE: High resolution ultrasonography has made it possible to detect many non-palpable small nodules in thyroid gland. We investigated the prevalence and clinical features of non-palpable thyroid nodule and carcinoma discovered incidentally at screening ultrasonography in healthy women. METHODS: A retrospective review was undertaken on the previous healthy asymptomatic 1, 714 women where selected to undergo screening ultrasonography for the detection of the presence of non-palpable thyroid nodules from January 2004 to December 2004. The aims of study were to define the prevalence of thyroid nodule and carcinoma in healthy asymptomatic women and to access the extent of disease in patients with malignant nodule by surgery. RESULTS: Of the 1, 714 subject, thyroid nodule were detected in 822 (48.0%) women with their prevalence increasing with the increasing age of patients. The malignant detection rate based on the USG-guided fine-needle aspiration (USGFNA) results, including both suspicious and malignant groups, was 2.8% (48/1, 714) of all subjects. 38 of 50 patients with malignant, suspicious or indeterminate cytology underwent surgery and all of them were confirmed to have papillary carcinoma on histological results. In 38 patients with papillary thyroid carcinoma, the average size of tumors was 0.87+/-0.33 cm, a range of 0.3 to 1.5 cm, multifocal tumors were found in 50% (19/38), bilaterality was found in 44.7% (17/38), extrathyroidal extension was observed in 50.0% (19/38), and regional lymph node metastasis was found in 29.4% (5/17). CONCLUSION: High resolution ultrasonography detected a high percentage (48%) of nonpalpable thyroid nodules. Characteristics of thyroid nodules on ultrasonography can be used to decision of optimal management strategies. Total thyroidectomy with lymph node dissection may be suitable in patients with non-palpable papillary thyroid carcinoma due to its high incidence of extrathyroidal extension, bilaterality and regional lymph node metastasis.

Foreign bodies in the upper esophagus should be removed as soon as possible to avoid serious complications. These foreign bodies can penetrate the bowel wall and cause severe complications. The peristalsis of the esophagus is not strong enough to prevent it from retaining swallowed objects. Hence, perforation from a foreign body is more likely to occur in the esophagus than in the rest of the gastrointestinal tract. A razor blade is a rare foreign body of the esophagus. Its sharpness and large size make it difficult to remove. A razor blade was very firmly impacted in the esophageal wall in our case, and the razor blade had not moved from the upper esophagus. A standard overtube has limitations to remove a razor blade inside the overtube's lumen. We report here on a case of using a wedge resected overtube made it possible to successfully extract a razor blade and no serious complications occurred after extraction of the razor blade.

Ischemic colitis is generally considered a disease of the elderly. The causes of ischemic colitis include low-flow states due to cardiac dysfunction or hypovolemia and certain medications including estrogen. Here we report a case of ischemic colitis in a 26-year-old woman. She had no specific medical history except taking oral-contraceptives for a long time. The mechanism of estrogen-induced ischemic colitis is not clearly understood. But we recommend that oral-contraceptives should be considered as a cause of ischemic colitis in young women.

OBJECTIVE: This study aimed to identify factors that affect in vitro fertilization (IVF) outcomes in women with diminished ovarian reserve (DOR). METHODS: We reviewed 99 IVF cycles in 52 women with DOR between September 2010 and January 2015. DOR was defined as serum anti-Müllerian hormone level of <1.1 ng/dL or serum follicle-stimulating hormone level of ≥20 mIU/mL. Total 96 cycles in 50 patients were evaluated after excluding fertility preservation cases. RESULTS: The clinical pregnancy rate was 11.5% per cycle, and the total cancellation rate was 34.4%. Clinical pregnancy rate was significantly associated with the antral follicle count and the cause of the DOR. Age, serum anti-Müllerian hormone and follicle-stimulating hormone levels, antral follicle count, peak estradiol level, and the cause of DOR were significantly associated with cycle cancellation. However, history of previous ovarian surgery remained as a significant factor of clinical pregnancy (model 1: odds ratio [OR] 10.17, 95% confidence interval [CI] 1.46 to 70.84, P=0.019; model 2: OR 10.85, 95% CI 1.05 to 111.71, P=0.045). In cancellation models, idiopathic or previous chemotherapy group showed borderline significance (model 1: OR 3.76, 95% CI 0.83 to 17.04, P=0.086; model 2: OR 3.15, 95% CI 0.84 to 11.84, P=0.09). CONCLUSION: DOR caused by previous ovarian surgery may show better pregnancy outcome, whereas that caused by chemotherapy could significantly increase the cycle cancellation rate. Furthermore, patients with DOR who previously received gonadotoxic agents may show reduced efficacy and increased risk of IVF cycle cancellation.

Objective: The objective of this review was to provide reliable comparative results regarding the effectiveness of any interventions either open or closed that can be used in the management of fractured mandibular condyle PATIENTS AND METHODS: Research of studies from MEDLINE and Cochrane since 1990 was done. Controlled vocabulary terms were used. MeSH Terms were "Mandibular condyle" AND "Fractures, bone". Only comparative study were considered in this review using the "limit" function. According to the criteria, two review authors independently assessed the abstracts of studies resulting from the searches. The studies were divided according to some criteria, and following were measured: Ramus height, condyle sagittal displacement, condyle Towns's image displacement, Maximum open length, Protrusion & Lateral excursion, TMJ pain, Malocclusion, and TMJ disorder. RESULTS: Many studies were analyzed to review the post-operative result of the two methods of treatment. Ramus height decreased more in when treated by closed reduction as opposed to open reduction. Sagittal condyle displacement was shown to be greater in closed reduction. Condyle Town's image condyle displacement had greater values in closed reduction. Maximum open length showed lower values in closed reduction. In protrusive and lateral movement, closed reduction was less than ORIF. Closed reduction showed greater occurrence of malocclusion than ORIF. However, post-operative pain and discomfort was greater in ORIF. CONCLUSION: In almost all categories, ORIF showed better results than CRIF. However, the use of the open reduction method should be considered due to the potential surgical morbidity and increased hospitalization time and cost. To these days, Endoscopic surgical techniques for ORIF (EORIF) are now in their infancy with the specific aims of eliminating concern for damage to the facial nerve and of reducing or eliminating facial scars. Before performing any types of treatment, patients must be understood of both of the treatment methods, and the best treatment method should be taken on permission.
