Broncho-gastric fistula caused by benign gastric ulcer perforation after esophagectomy is very rare. In general anesthesia of a patient with broncho-gastric fistula, in spite of hyperventilation, leakage of the anesthetic gases through fistula may make the patient hypercapneic, and positive pressure ventilation may increase the risk of the pulmanary aspiration by the regurgitation of gastric fluid by stomach distension. For that reason, in this patient, denitrogenation was performed during patient's voluntary respiration with 100% oxygen for 5 minutes, and induction was performed without positive pressure ventilation, and one lung ventilation was carried out. Hypoxemia was followed by one lung ventilation because his pulmonary function was moderate obstructive type and his lung was damaged by aspiration of gastric fluid via broncho-gastric fistula. A low level of continuous positive airway pressure (CPAP) has no significant hemodynamic effect and can maintain the patency of nonventilated lung, so hypoxemia induced by one lung ventilation may be reduced. Thus we carried out one lung ventilation with CPAP (10 cmH2O) in nonventilated lung and blocked broncho-gastric fistula with a bronchial blocker for prevention of both regurgitation of gastric fluid and leakage of anesthetic gases. One lung anesthesia was performed without any problem in this case.

The expression of c-fos and c-jun in the brain of the rat after capsaicin treatment was investigated by in situ hybridization, dot blot hybridization and immunocytochemical methods. Adult male Sprague-Dawley rats[200g] were used for this study. The first set of rats received a single subcutaneous injection of capsaicin[50mg/Kg] dissolved in 10% Tween-80 and 10% ethanol in saline. The rats were decapitated 1, 3, 5, 10, 24, 72 hours and 1 week after capsaicin treatment. The control set of rats were treated with saline instead of capsaicin. In situ hybridization and dot blot hybridization were carried out. O1igonucleotide probe complimentary to c-fos mRNA sequences were used for this study and labeling of oligonucleotides was accomplished using the DNA tailing kit. The expression of c-fos mRNA on the nucleus of neurons in in situ hybridization was observed throughout the brain, and was especially abundant in the olfactory cortex, nucleus of diagonal band of Broca, habenular nuclei, periaqueductal gray, parabrachial nucleus, entopeduncular nucleus, ventral posterolateral nucleus of the thalamus and cerebellum. Compared to the control rats, c-fos mRNA were increased 24 hours after capsaicin injection and gradually decreased after 72 hours, returning to the normal control level 1 week after capsaicin injection. c-fos mRNA was detected only 1 week after capsaicin injection in the various areas of the brain. The fos protein-like immunoreactivity was initially somewhat decreased at 24 hours, but increased at 72 hours and reactions was maximally observed at 1 week after capsaicin treatment. But Jun protein immunoreactivity was not increased, on the contrary, it was even decreased both in numbers of reactive cells and immunoreactivity 1 week after capsaicin injection. From the above results, c-fos gene expression was pronounced in the nucleus concerned with pain, olfaction and taste such as VPL nucleus of the thalamus, olfactory cortex and parabrachial nucleus, in the limbic system concerned with stress and emotion such as nucleus of diagonal band of Broca, periaqueductal gray and habenular nucleus, in the structure concerned with somatic motor function such as entopeduncular nucleus and cerebellum. Also, the c-fos gene was activated by the capsaicin early in the course of effects, then the fos protein increased as a results of c-fos activation. On the other hand, c-jun did not respond to capsaicin treatment early in the course, but Jun protein decreased late in the course of capsaicin effects.

OBJECTIVE: To assess the effect of recombinant human leukemia inhibitory factor on in vitro development of 1-cell ICR mouse embryo. MATERIALS AND METHOD: ICR mice were superovulated with PMSG/hCG and 1-cell stage mouse embryos were recruited. 1-cell mouse embryo were cocultured on human oviductal cells in a CO2 incubator (coculture group) and were cultured on 0.4% BSA+HTF media (control group). And anti-hLIF Ab was added the cocultured group in a different concentration (1pg, 10pg, 100pg, 1ng) and developmental rate was compaired to the control group, and rhLIF was added to the preincubated 0.4% BSA+HTF media in a different concentration (2000U, 1000U, 100U, 10U) and its developmental rate was compaired to group which was cultured on 0.4% BSA+HTF media only. RESULT: 1. The cleavage rate of 2-cell mouse embryo co-cultured with human tubal epithelial cell was significantly higher than that of cultured with media alone (HTF with 0.4% BSA) (p<0.05). 2. When LIF antibody was added to the medium with human tubal epitherlial cell, the mouse embryo could not cleave more than 2-cell in 1 ng of LIF antibody, and less than 1 ng, the cleavage rate was lower than cultured without LIF antibody group(p<0.05). 3. Two cell blocked ICR mouse embryos were developed into four cells under LIF(p<0.05), but no further development was observed. CONCLUSIONS: These results shows that LIF enhances the development of preimplantation embryo, and when rhLIF is applicated in vitro, it has positive effects on the development of early mouse embryo and can help overcoming the two-cell block.

PURPOSE: The sunken chest deformity without breast asymmetry is not a rare condition encountered in augmentation mammaplasty. Therefore, failure to recognize the deformity and improper surgical plan will lead to a suboptimal result. The authors review the experience of breast augmentation in simple sunken chest patient based on retrospectively collected data. METHODS: From January, 2008 to January, 2009, patients with simple sunken chest underwent endoscopic submuscular augmentation mammaplasty through axilla, using silicone implants. Patient demographics were queried and outcomes were assessed. RESULTS: Eleven patients (22 breasts) were followed up for 8.2 months after surgery. Sunken chests were augmented with implant size of approximately 248.9 cc (range: 213~286 cc) and contralateral chest with 211.4 cc (range: 180~235 cc). Simultaneous camouflaging the chest wall depression with breast augmentation resulted in good aesthetic outcome. All of the patients were satisfied with the surgery. There were no complications among all patients. CONCLUSION: We have demonstrated proper surgical planning with precise implant selection to optimize results in patients with small breast and simple sunken chest. Even though asymmetry still remains after the operation, it is still considered as acceptable.

BACKGROUND: This study aims to determine whether significant associations exist between the parents' country of birth and adolescent depressive symptoms in the early stages of a multicultural society. METHODS: We used data from the 2012–2016 Korea Youth Risk Behavior Web-based Survey, which included responses from 327,357 individuals. Participants were classified into groups according to their parent's country of birth. Logistic regression analysis was used to examine the significance of the associations. RESULTS: Adolescents whose parents were born abroad are more likely to have depressive symptoms (odds ratio [OR] = 1.68; 95% confidence interval [CI], 1.33–2.12) than adolescents whose parents were native Koreans. Respondents whose father was born in North Korea or Japan or Taiwan show greater odds of depressive symptoms than respondents whose parents were native Korean. CONCLUSION: Adolescents whose parents were born abroad are more likely to have depressive symptoms. Multicultural family support policies should be implemented in consideration of the characteristics of the parents' country of birth.

Glomerulonephritis associated with malignancy is deemed to be paraneoplastic glomerulonephritis. Myelodysplastic syndrome (MDS) is a group of heterogeneous clonal hematopoietic stem cell disorders characterized by impaired hematopoietic cell differentiation and cytopenia. The pathophysiology of MDS is thought to be immune-mediated in part. A few reports have documented various forms of glomerulonephritis in patients with MDS and suggested that immune dysregulation is important in the development of paraneoplastic glomerulonephritis. Here, we report a patient with MDS and refractory anemia with excess blast-2 accompanied by minimal change nephrotic syndrome. The patient was treated with prednisolone, and the nephrotic-range proteinuria and pancytopenia improved markedly.

Small bowel variceal bleeding is a rare cause of gastrointestinal hemorrhage, with clinical manifestations ranging from asymptomatic incidental findings to life-threatening conditions. The diagnosis and management of small bowel bleeding are challenging because of the localization of the lesion and the difficulty of the procedure. Trans-arterial embolization (TAE) is a secure and straightforward method for treating ectopic varices. On the other hand, there have been limited local studies on the outcomes of TAE for patients with small bowel variceal hemorrhage. This paper reports patients diagnosed with small bowel variceal bleeding and treated with TAE.

PURPOSE: There are several modalities to reattach the amputated auricle. Although microvascular replantation can achieve the best outcome, it is technically difficult. Conventional composite graft is technically easy, but uniformly unsuccessful. Our successful experience of reattachment using postauricular subcutaneous pocket is presented. METHODS: The amputated tissue was placed in its anatomical position with buried sutures. The amputated part is dermabraded to remove the epidermis and outer layer of dermis(Fig. 1, Center, left). Postauricular skin flap was then raised and the reattached dermabraded ear was buried beneath the flap(Fig. 1, Center, right). Two weeks after the original surgery, the buried ear was removed from its pocket(Fig. 1, Below, left). RESULTS: The ear was reepithelialized spontaneously in 7 days. In 3 months, the reattached ear shows satisfactory appearance without contour deformity(Fig. 1, Below, right). CONCLUSION: This technique provides increase in contact surface between the amputated segment and the surrounding tissues which supply blood, serum, oxygen and nutrients, maximizing the probability of "take". Minimally injured dermis can be healed from spontaneous reepithelialization and provides minimal contour deformity. We have used this non-microsurgical technique with very satisfying outcome.

PURPOSE: Fine needle aspiration (FNA) is a useful preoperative diagnostic tool for thyroid nodule because of the high sensitivity and specificity. The aim of this study is to determine the necessity of intraoperative frozen section (IOFS) after fine needle aspiration. METHODS: Data of 534 patients with a single thyroid nodule who underwent thyroidectomy from June 2006 to August 2013 were reviewed retrospectively. FNA was performed preoperatively in all patients and IOFS was performed selectively according to the intraoperative findings and FNA results. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of FNA and IOFS for malignant nodules were analyzed. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FNA for malignant nodules were 100%, 95.5%, 99.8%, 100%, and 99.8%, respectively. All nodules diagnosed as benign by FNA were reaffirmed as benign nodules by permanent sections. When the result of FNA was suspicious for malignancy, specific features of preoperative ultrasound, including hypoechoic, size<10 mm showed high positive predictive value and accuracy (98%, 86.9%, and 100%, 78.7% respectively). CONCLUSION: Performance of IOFS was not necessary when the result of FNA was consistent with malignancy or benign. However when the result of FNA was non-diagnostic or atypia, IOFS should be performed for more accurate detection of malignancy. When the result of FNA is suspicious for malignancy, IOFS is restrictively useful for excluding benign nodules using the features of ultrasound. In addition, IOFS is not useful in finding malignant thyroid nodules when the result of FNA is follicular neoplasm.

PURPOSE: The aim of this study was to determine whether crossed cerebellar hyperperfusion (CCH) was helpful in discriminating mesial from lateral temporal lobe epilepsy (TLE) and what other factors were related in the development of CCH on ictal brain SPECT. MATERALS AND METHODS: We conducted retrospective analysis in 59 patients with TLE (M:41, F:18; 27.4+/-7.8 years old; mesial TLE: 51, lateral TLE: 8), which was confirmed by invasive EEG and surgical outcome (Engel class I , II). All the patients underwent ictal Tc-99m HMPAO brain SPECT and their injection time from ictal EEG onset on video EEG monitoring ranged from 11 sec to 75 sec (32.6+/-19.5 sec) in 39 patients. Multiple factors including age, TLE subtype (mesial TLE or lateral TLE), propagation pattern (hyperperfusion localized to temporal lobes, spread to adjacent lobes or contralateral hemisphere) and injection time were evaluated for their relationship with CCH using multiple logistic regression analysis RESULTS: CCH was observed in 18 among 59 patients. CCH developed in 29% (15/51) of mesial TLE patients and 38% (3/8) of lateral TLE patients. CCH was associated with propagation pattern; no CCH (0/13) in patients with hyperperfusion localized to temporal lobe, 30% (7/23) in patients with propagation to adjacent lobes, 48% (11/23) to contralateral hemisphere. Multiple logistic regression analysis revealed that propagation pattern (p=0.01) and age (p=0.02) were related to the development of CCH. CONCLUSION: Crossed cerebellar hyperperfusio ictal brain SPECT did not help differentiate mesial from lateral temporal lobe epilepsy. Crossed cerebellar hyperperfusion was associated with propagation pattern of temporal lobe epilepsy and age.
