BACKGROUND: In the majority of cases, sternal instability and wound infection concomitantly present after a cardiac operation following conventional median sternotomy, and these complications have a major influence on the postoperative course. The aim of this study is to compare the results of the different sternal wiring techniques on sternal infection. MATERIAL AND METHOD: Between April 2004 and December 2008, 157 adult patients underwent cardiac operation through a median sternotomy. 86 patients who had undergone standard peristernal wiring were included in group A, whereas 71 patients who had undergone modified Robicsek sternal wiring were included in group B. The incidences of sternal wound complications in the two groups were assessed. RESULT: The mean age of the group B patients was older than that of the group A patients (61+/-10 years vs 57+/-13 years). The incidence of preoperative left ventricular dysfunction (ejection fraction <30%), chronic obstructive pulmonary disease, renal failure requiring dialysis and diabetes mellitus were significantly higher in Group B, whereas the other perioperative risk factors for infection were not significantly different between the two groups. Two patients in group A experienced superficial wound infection, whereas 4 patients in group B displayed superficial wound infection, but the difference was not statistically significant (p=0.255). Yet poststernotomy deep sternal wound infection appeared in 6 patients of group A, whereas none of the patients in group B displayed this malady. CONCLUSION: The modified Robicsek sternal wiring technique showed greater sternal stability even for the patient with a high risk for infection, and the technique caused a lower incidence of deep sternal wound infection.

OBJECTIVE: To investigate whether GnRH-agonist (GnRH-Ag) using in IVF-ET affects apoptosis of human granulosa-luteal cells and expression of peripheral benzodiazepine receptor (PBR) protein involved in the apoptosis of the cells. METHODS: Granulosa-luteal cells obtained during oocyte retrieval were cultured and treated with 10(-5) M GnRH-Ag. Apoptosis of the cells by the treatment was confirmed using DNA fragmentation analysis 24 h after culture. The presence of PBR protein within the cells was examined by immunofluorescence staining and the expression of the protein was analyzed by Western blotting. In addition, it was measured for progesterone and nitric oxide (NO) produced by granulosa-luteal cells after GnRH-Ag treatment. To evaluate the relationship between NO production and PBR expression, sodium nitroprusside (SNP) as a NO donor was added in media and investigated the expression of PBR protein by Western blotting. RESULTS: Apoptosis increased in the granulosa-luteal cells 24 h after GnRH-Ag treatment, whereas the expression of PBR protein significantly decreased. Furthermore, the production of progesterone and nitric oxide (NO) by the cells significantly fell from 12 h after the treatment. In the results of Western blotting after SNP treatment, the expression of PBR protein increased in the treatment with SNP alone to the granulosa-luteal cells, but was suppressed in the treatment with GnRH-Ag and SNP. Additionally, the staining result of PBR protein in the cells showed the even distribution of it through the cell. CONCLUSION: These results demonstrate that GnRH-Ag treatment induces apoptosis, decreasing expression of PBR protein and NO production in human granulosa-luteal cells. The present study suggests that one of the apoptosis mechanism of human granulosa-luteal cells by GnRH-Ag might be a signal transduction pathway via NO and PBR.

An 81-year-old woman was admitted to our hospital with bilateral chest wall mass in the infrascapular region. Considering the possible diagnosis of a malignant chest wall tumor at such location, we performed excision and biopsy. Both masses were histologically diagnosed as elastofibroma. We experienced this rare disease, bilateral elastofibroma, so we report this case with a bibliography.

PURPOSE: This study aimed to examine the following questions: to what extent do patients and caregivers perceive their family members to be avoidant of communication regarding patient's cancer, and to what extent do these perceptions interrelate; and how do such perceptions influence their own and each other's communication behaviors, communication outcome, mental health, and quality of life. MATERIALS AND METHODS: A national survey was performed with 990 patient-caregiver dyads (participation rate, 76.2%). To examine the dyadic interaction, we developed linked patient and family member questionnaires, including the Family Avoidance of Communication about Cancer (FACC) scale. RESULTS: The mean scores (standard deviations) of patient- and caregiver-perceived FACC were low at 10.9 (15.5) and 15.5 (17.5), respectively (p < 0.001), and concordance was low, a well (Spearman's rho, 0.23). Patient-perceived FACC was associated with lower levels of disclosure and behaviors of holding back communication, as well as lower levels of mental health outcome and quality of life. The same was true for caregivers (all p < 0.05). Patient-perceived FACC was associated with caregiver holding back, caregiver's depression level, and caregiver quality of life (all p < 0.05). Both patient- and caregiver-perceived FACC were independently associated with communication difficulty within the family. CONCLUSION: Future research would benefit from the measurement of FACC from both patients and caregivers, and promote family intervention to enhance openness to communication, which would be helpful for improving mental health and quality of life for both patients and caregivers.

BACKGROUND: Malignant pleural effusion is a common condition in neoplastic patients and palliative therapy is the usual treatment. Talc has been generally accepted to be the most effective sclerosant for chemical pleurodesis, but the optimal route of administration remains controversy. We compared the results of video-assisted thoracoscopic talc poudrage (VTP) with administering a bedside talc slurry through a chest tube (BTS) for the treatment of malignant pleural effusion. MATERIAL AND METHOD: From December 2004 to May 2006, 20 patients with malignant pleural effusion underwent chemical pleurodesis via VTP (group A, n=10), and BTS (group B, n=10). RESULT:The durations of chest tube placement after the procedure were 7.0+/-4.0 days (group A) and 6.7+/-3.6 days (group B). The hospital stays were 24.3+/-9.4 days (group A) and 30.7+/-21.5 days (group B), respectively. The symptoms of dyspnea were much more improved in group A (p-value=0.014) after discharge (mean f/u group A=8.5+/-2.2 months, group B 8.0+/-7.4 months). The collapsed portions of lung were better expanded in group A than in group B (p-value= 0.011). CONCLUSION: We recommend VTP for the selected patients with malignant pleural effusion because of the advantages of dissecting the fibrous peel to relieve the atelectasis and dyspnea, and excising the pleura for diagnosis with direct viewing of the lesion.

The demineralized bone matrix (DBM) as the bone graft material to increase the fusion rate was widely used in spinal fusion. The current study aimed to compare the fusion rate of DBM to the fusion rate of autograft in lumbar spine fusion via meta-analysis of published literature. After systematic search, comparative studies were selected according to eligibility criteria. Checklist (risk of bias assessment tool for non-randomized study) was used to evaluate the risk of bias of the included nonrandomized controlled studies. The corresponding 95% confidence interval (95% CI) were calculated. We also used subgroup analysis to analyze the fusion rate of posterolateral lumbar fusion and lumbar interbody fusion. Eight studies were finally included in this meta-analysis. These eight studies included 581 patients. Among them, 337 patients underwent spinal fusion surgery using DBM (DBM group) and 204 patients underwent spinal fusion surgery with mainly autologous bone and without using DBM (control group). There was no significant differences of fusion rate between the two groups in posterolateral fusion analysis (risk ratio [RR], 1.03; 95% CI, 0.90–1.17; p=0.66) and interbody fusion analysis (RR, 1.13; 95% CI, 0.91–1.39; p=0.27). Based on the available evidence, the use of DBM with autograft in posterolateral lumbar spine fusion and lumbar interbody fusion showed a slightly higher fusion rate than that of autograft alone; however, there was no statistically different between two groups.

Infected aneurysms are uncommon, frequently fatal lesions. "True" fungus-infected aneurysms are even rarer. Fungal infections have high morbidity and mortality. However, diagnosis is frequently difficult, since the symptoms are non-specific and standard diagnostic procedures are often insensitive. We experienced a patient with persistent fever and negative blood cultures. The patient was immunocompetent and had no risk factors, and was diagnosed with a fungus-infected aneurysm based on computed tomography and vascular surgery. The vascular tissue revealed some narrow-based budding yeast within the thrombus, suggesting Candida infection. Seventeen cases of infected aneurysm of the abdomen were reported in Korea from 1988 to 2007, although none were "true" fungus-infected aneurysms, making this the first fungus-infected aneurysm of the abdomen in Korea. Prompt diagnostic procedures and aggressive treatment modalities are necessary for patients with occult infection and negative blood cultures, regardless of their immunocompetence, because of the high morbidity and mortality of this condition.

The characteristic features of Churg-Strauss syndrome are vasculitis, both intra- and extravascular granuloma formation with eosinophilic tissue infiltration, and strong association with asthma and peripheral eosinophilia. Churg-Strauss syndrome with pleural effusion is relatively common and only a few cases have previously been reported in Korea. We report a case of Churg-Strauss syndrome with pleural effusion confirmed by VATS.

BACKGROUND AND OBJECTIVES: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician's diagnostic and therapeutic approaches for BPPV. MATERIALS AND METHODS: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. RESULTS: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). CONCLUSION: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.
