OBJECTIVE: Whether exposure to chronic noise induces an increase in blood pressure, or the development of hypertension, has not been established. A cohort study was performed to identify the effects of chronic noise exposure on blood pressure. METHODS: 530 males working at a metal manufacturing factory in Busan, Korea were enrolled for the study. They were monitored for 9 consecutive years, from 1991 to 1999, with an annual health check-up. The subjects were divided into 4 groups, which were determines by noise level categories(NLC) according to noise intensity ; NLC-I: office workers, exposed to noise a level below 60dB(A); NLC-II: field technical supporters or supervisors, frequently exposed to workplace noise, wearing no hearing protection device; NLC-III: workers, exposed to workplace noise below 85 dB(A), wearing ear plugs or muffs; NLC-IV: workers, exposed to workplace noise over 85 dB(A), wearing both ear plugs and muffs. RESULTS: After controlling possible confoundens, such as baseline age, smoking, alcohol intake, exercise, family history of hypertension, systolic(SBP) or diastolic blood pressure(DBP) and changes in BMI (body mass index), the pooled mean for the systolic blood pressures, over the duration of the study period, were 3.8mmHg, 2.0mmHg and 1.7mmHg higher in NLC-IV, NLC-III NLC-II groups, respectively, than in the NLC-I group. There were no significant differences in the diastolic blood pressures between the groups. CONCLUSION: This study suggests that chronic noise exposure increases systolic blood pressure independently, among male workers.

Chronic rhinosinusitis (CRS) is further classified as CRS with nasal polyp and CRS without nasal polyp. It is also divided into type 2 and none-type 2 by immunological endotype. Nowadays, novel biological products targeting type 2 inflammation are developed and used for the treatment of CRS with nasal polyp.Current Concepts: Dupilumab, which inhibits interleukin-4 and interleukin-13, and omalizumab, which targets immunoglobulin E, were recently approved and are currently being used as the treatment regimen for patients with recurrent CRS with nasal polyp in Korea. Many studies demonstrated enough effects of both biological products on nasal symptoms, including smell, quality of life, and polyp size. The indication of biological products is refractory CRS with nasal polyp with severe symptoms even after endoscopic sinus surgery. However, the main drawback of these biological products is a high cost since they are non-reimbursement regimens as defined by Korean national health insurance.Discussion and Conclusion: Further research on the use of dupilumab and omalizumab in Korean patients will be needed because the Korean CRS endotype, which is characterized by less-type-2 CRS, is different from Western CRS endotypes. Additionally, investigations on the comparison of efficacy among various biological products are essential to prescribe the most appropriate biological products depending on the patients’ endotypes.

BACKGROUND: Infarct size determines left ventricular (LV) systolic and diastolic dysfunctions after acute myocardial infarction, and also may affect the recovery from functional impairment. We studied the differences of LV remodeling and changes of systolic and diastolic functions of LV during two weeks after acute myocardial infarction, according to Killip class at admission. METHODS: Echocardiographic examinations were performed within two days (23.9+/-2.3 hours), and two weeks after the attack in 27 patients with acute myocardial infarction, and the results were compared with those of 19 controls. Patients were divided into two groups according to Killip class at admission; 18 patients in Killip class I (group I) and 9 patients in Killip class II to IV (group II). Group II had larger infarct, reflected by higher levels of peak serum cardiac enzymes. RESULTS: LV systolic function was more depressed in group II. Regional wall motion score index decreased in group I after two weeks, but not in group II. LV systolic and diastolic volume indexes increased after two weeks in group II but not group I. E/A ratio of mitral inflow was less than 1, and isovolumic relaxation time was prolonged in group I immediately after the attack. Group II had E/A>1 and shorter deceleration time (DT) of mitral inflow, and higher peak reverse flow velocity associated with atrial contraction (AR) of pulmonary venous flow than those of controls immediately after the attack. In group II, E/A ratio was greater, DT was shorter, peak systolic/diastolic flow velocity ratio of pulmonary venous flow was less, and AR was higher than those of controls after two weeks. CONCLUSION: Infarct size affected remodeling and changes of systolic and diastolic functions of LV after acute myocardial infarction. In patients with large infarct, LV was dilated and regional wall motion was not improved during two weeks. Restrictive pattern of LV filling, which was more aggravated during two weeks, was noted immediately after the attack. In patients with small infarct, LV was not dilated and regional wall motion was improved during two weeks. LV filling pattern showed relaxation abnormality.

Fibrous dysplasia (FD) is a non-malignant progressive condition, which replaces normal bone and marrow with fibrous tissue and woven bone. Sinus mucocele is a cystic, expansile, and destructive lesion that occurs as a result of obstruction of the sinus ostium secondary to inflammation, trauma, anatomical variation, previous sinus surgery, tumor or FD. Among them, FD combined with mucocele has been rarely reported. Here we report the first case of FD combined with ethmoid mucocele. The patient underwent endoscopic debulking of FD and marsupialization of mucocele. The mucocele was successfully marsupialized, and the patient’s symptoms were completely resolved. We propose a new hypothesis that nasal mucosa invaginates into FD and forms a mucocele. For the treatment of ethmoid FD combined with mucocele, we recommend an endoscopic transnasal approach for debulking and marsupialization.

BACKGROUND: The purpose of this study was to report findings of exploratory arthroscopic assessment performed in conjunction with removal of internal fixation device placed in the initial surgery for rotational ankle fracture. METHODS: A total of 53 patients (33 male, 20 female) who underwent surgery for rotational ankle fracture between November 2002 and February 2008 were retrospectively reviewed. All patients gave consent to the exploratory arthroscopic surgery for the removal of internal fixation devices placed in the initial surgery. Lauge-Hansen classification system of ankle fractures was assessed for all patients. Intra-articular lesions (osteochondral lesion, loose body, and fibrosis) were evaluated via ankle arthroscopy. Comparative analysis was then performed between radiological classification of ankle fracture/patient's symptoms and arthroscopic findings. RESULTS: Lauge-Hansen classification system of ankle fractures included supination-external rotation type (n = 35), pronation-external rotation type (n = 9), and pronation-abduction type (n = 9). A total of 33 patients exhibited symptoms of pain or discomfort while walking whereas 20 exhibited no symptoms. Arthroscopic findings included abnormal findings around the syndesmosis area (n = 35), intra-articular fibrosis (n = 51), osteochondral lesions of the talus (n = 33), loose bodies (n = 6), synovitis (n = 13), and anterior bony impingement syndrome (n = 3). Intra-articular fibrosis was seen in 31 of symptomatic patients (93.9%). Pain or discomfort with activity caused by soft tissue impingement with meniscus-like intra-articular fibrosis were found in 19 patients. There was statistical significance (p = 0.02) between symptoms (pain and discomfort) and the findings of meniscus-like fibrosis compared to the group without any symptom. CONCLUSIONS: Arthroscopic examination combined with treatment of intra-articular fibrosis arising from ankle fracture surgery may help improve surgical outcomes.

BACKGROUND: The rate of rise of left ventricular(LV) systolic pressure, dp/kt, and the peak ejection rate(PER) of LV may be more accurate indices for assessing LV systolic function than ejection fraction(EF). Both can be easily obtained by noninvasive methods, M-mode echo/phonocardiography and automated border detection(ABD) echocardiography, respectively. Mean dp/dt by M-mode echo/phonocardiography and PER by ABD echocardiography were compared with mean dp/dt by Doppler echocardiography. METHODS: Twenty-one adult patients who had normal sinus rhythm, mitral regurgitant signals by continuous wave Doppler echocardiography and an apical 4 chamber view of LV in which at least 75% of the endocardium was clearly visualized were selected for our study. The off-line estimation of LV end-diastolic volume (1) were performed by the method of disc, after manually tracing the endocardial border on the apical 4 chamber view and EF was calculated. M-mode echocardiography of the aortive valve and phonocardiography were simultaneously recorded on the strip chart to measure the isovolumic contraction time(dtM). A blood pressure (2) and LV end-diasolic pressure(LVEDP) was assigned 20mmHg in patients with Q wave myocardial infarction or EF< or =40% and 10mmHg in others. The mean dp/dtM during isovolumic contraction time was calculated as (aortic diastolic pressure-LVEDP)/dtM and was compared with the Doppler-derived mean rate of LV pressure rise(dp/dtDoppler) over the time period between velocities of 1 and 3m/sec on the ascending slope of the Doppler velocity spectrum. ABD system was used to measure the changes in LV volume and PER on the apical four chamber view. PER was compared with mean dp/dtDoppler. RESULTS: Mean dp/dtM positively correlated with mean dp/dtDoppler(r=0.73, p<0.001), but the limits of agreement between two methods were somewhat wide(-659-937mmHg/sec). PER also positively correlated with dp/dtDoppler and EF(r=0.73, p<0.001 ; r=0.80, p<0.001). CONCLUSIONS: Mean dp/dtM by M-mode echo/phomocardiography and PER by ABD echocardiography may be useful indices for assessing LV systolic function.

A 48-year-old woman with cystic fibrosis and a previous left pneumonectomy had surgery planned for single lung transplantation under general anesthesia. Due to progressive dyspnea and recurrent respiratory infection, she could not maintain her normal daily life without lung transplantation. The anesthetic management and surgical procedure was expected to be difficult because of the left mediastinal shift and an asymmetric thorax after the left pneumonectomy, but the single lung transplantation was successfully done under cardiopulmonary bypass.

We report our initial experiences of a laparoscopic radical prostatectomy through an intraperitoneal approach. Two patients with an adenocarcinoma of the prostate underwent operations. The procedures for achieving a complete removal, vesicourethral anastomosis, operative time, blood loss, hospital stay, pathologic findings, continence, and potency were evaluated in both cases. Complete removals of the prostates and seminal vesicles were achieved in both cases. Reconstructions of the bladder neck with a watertight anastomosis were successful. The surgery time was 9 hours and 5 minutes, 6 hours and 30 minutes in each, with an estimated blood loss of approximately 800 and 400cc. The hospital stay was 15 days and 12 days. The final pathologic evaluation was a stage T3a (Gleason score; 7) and stage T2a (Gleason score; 6) disease with a negative margin. A laparoscopic radical prostatectomy is feasible and offers an advantage over open surgery with regard to the length of stay, convalescence time, cosmetic results, continence, and potency.
