In effort to determine whether aircraft noise can have health effects such as hearing loss, hypertension and psychological stress, a total of 111 male professors and administrative officers working a college near a military airport in Korea(exposed group) and a total of 168 males and 112 females matched by age groups(control groups) were analyzed. Personal noise exposure and indoor and outdoor sound level of jet aircraft noise were measured at the exposed area. And pure tone, air conduction test and measurement of blood pressure were given to the exposed(males) and matched control groups(males and females). BEPSI(Brief Encounter Psychological Instrument) and psychological response to aircraft noise were examined for the exposed group. The noise dosimetry results revealed time-weighted averages(TWAs) that ranged from 61 to 68 dBA. However the levels encountered during taking off jet airplanes reached 126 dBA for two half minutes time period. The audiometric test showed that mean values of HTL(hearing threshold level) in exposed group at every frequency(500, 1,000, 2,000, 4,000, and 8,000 Hz were much lower than them of male and female control groups. And in old age groups, interaction of age and noise was observed at 8,000 Hz in both ears(p< 0.05). Conclusively, aircraft noise does not appear to induce hearing loss directly, but may decreased hearing threshold level by interaction of aging process and noise exposure. However, difference of mean values of exposed and control groups on blood pressure was not significantly. In psychological test, annoyance was the most severe psychological response to noise in exposed group, but mean value of BEPSI was not correlated with job duration in exposed group

Purpose:
To report a case of successful treatment of bilateral infectious keratitis combined with endophthalmitis caused by Pseudomonas aeruginosa in an immunocompromised patient.Case summary: A 66-year-old male with colon cancer and lung metastasis was referred to our clinic with ocular pain and reduced visual acuity in both eyes for 3 days. Visual acuity was “light perception” in both eyes at the first visit. On slit lamp examination, he presented with corneal central necrosis with mucopurulent discharge and anterior chamber hypopyon in both eyes. The left eye especially had vitreous haziness using a B-scan. Pseudomonas aeruginosa was detected in the corneal scrape culture and percutaneous transhepatic biliary drainage culture. After administration of topical eye drops, intravitreal injection, and systemic antibiotics, visual acuity improved from “light perception” to 20/63 in the right eye and to 20/125 in the left eye.
Conclusions
Although bilateral corneal ulcers combined with endophthalmitis induced by Pseudomonas aeruginosa are rare it can occur in immunocompromised patients. In the case of corneal ulcers combined with endophthalmitis, thorough ocular examinations and active treatments with intravitreal injections and systemic administration of antibiotics can help to recover vision.

Penile metastases are rare, and usually secondary to other genitourinary primary tumors. Bladder, prostate and renal tumors are the main sources of penile metastasis. Rectal and respiratory neoplasms also metastasize to the penis. However, metastatic penile cancer originating from the pancreas is extremely rare. Here, a case of pancreatic cancer, with penile metastasis, is reported.

A lymphoma of the prostate is very rare, and is usually incidentally discovered. Malignant lymphomas can be divided into either primary or secondary according to their origin. Secondary involvement of the gland is the most common presentation. Most non-Hodgkin's lymphomas that affect the prostate are of the B-cell type, and present with non-specific obstructive symptoms. A variety of methods have been used for their, including prostatectomy, radiotherapy or combinations of chemotherapy and radiotherapy. However, the prognosis remains poor, regardless of the patient's age, histological type, treatment or clinical stage at presentation. Here, the case of a patient with a B-cell lymphoma, who presented with symptoms of a bladder outlet obstruction, is reported. The patient has been in complete remission following the completion of 6 cycles of doxorubicin-based chemotherapy and accompanying radiotherapy.

Although occupational low back pain accounts for 20~40% of all occupational illness and injury, there are limited numbers of studies regarding the effectiveness of back school program. The objective of this study was to evaluate the economic benefit of back school program for early return to work of occupational low back pain patients in the current occupational injury compensation and management system. The cost-benefit analysis in this study was conducted to evaluate the relative magnitude of benefit to cost. The total cost was estimated by calculating the value of components in back school program according to governmental budget protocol. The back school program was consisted of three major approaches, pain center, work-hardening program and functional restoration program and each of components had various facilities and experts. The total amount of cost was estimated as 250,866,220 won per year. The most promising type of back school program were quite intensive (a 3 to 5-week stay in a specialized center), therefore, if we adopted the 5-week stay course, 10 courses could be held in a year. Following to the medical act, 20 patients per doctor could participate in a each course, ie, total 200 patients in a year. As a result, we could estimate the cost of 1,254,331 won a patient. we estimated the benefit by using data of a few local labor offices about average medical treatment beneficiary and off-duty beneficiary of 46 occupational low back pain patients in 1994. Ullman and Larsson(1977) mentioned that the group of chronic low back pain patients who participated in back school program needed less time to recover by 48.4% of beneficiary duration. And in the trying to estimate the benefit, we asked 10 rehabilitation board certificate doctors about reduction proportion of treatment cost by introducing back school program. The answered reduction proportions were in the range of 30~45%, average 39%. As a final result, we could see that the introduction of back school program in treatment of chronic occupational low back pain patients could produce the benefit to cost ratio as 3.90 and 6.28. And we could conclude that the introduction of back school program was beneficial to current occupational injury compensation and management system.

PURPOSE: Effective chest compressions may improve the return of spontaneous circulation and positive neurologic outcomes in cardiac arrest victims. Out of concern for rescuer fatigue, guidelines for cardiopulmonary resuscitation (CPR) recommend that the individual applying chest compressions should be switched every 2 minutes, but there is little evidence to support this recommendation. In this study, we investigated whether or not changing the individual who is applying chest compressions every 2 minutes during cardiopulmonary resuscitation is appropriate or not. METHODS: We recruited health personnel working at one university hospital on a volunteer basis. On a randomly assigned day, we compared the effectiveness of the use of multiple rescuers following the 2 minute guideline, versus single rescuer (rescuer-limited) in performance of CPR. The resulting data was collected by use of CPR recording technology, and chest compression quality variables including compression rate, compression depth, proportion of adequate compression depth, and proportion of incomplete recoil were recorded. RESULTS: There were statistically significant improvements in the rescuer-limited trial outcome including average compression depth (p=0.013), proportion of adequate compression depth (p=0.027), and difference in reported fatigue (0.007). CONCLUSION: In this study, we found that a rescuer-limited method is more effective than the multiple rescuer method in terms of subjective fatigue and chest compression quality metrics.

A cross-sectional study was conducted to assess the association between perceived occu-pational psychosocial stress at work and the work-related musculoskeletal disorders (WRMSD) among employees using video display terminals. The study included 111 female telecommunication employees from three companies at ChungBuk province. Cases of WRMSD were defined using symptom questionnaire and physical examination conducted by rehabilitation specialist. Information on demographics, individual factors, and perceived psychosocial stress, were obtained by self-administered questionnaire. For assessing perceived psychosocial stress, we used variables from 'job strain model' proposed by Karasek. Associations between perceived psychosocial stress and WRMSD were assessed by multiple logistic regression models. Forty nine (44% to the total) subjects met our operational definition for WRMSD. Age, seniority, housing load were not associated with WRMSD. Perceived psychosocial stress was associated with WRMSD [odds ratio=3.28, 95% confidence interval: 1.05-10.19]. This study suggests that perceived occupational psychosocial stress is related to the prevalence of WRMSD.

Obstructive jaundice produced by periportal tuberculous adenitis in the absence of pulmonary tuberculosis is quite rare. We are reporting the case of a 58-year-old woman who presented with constitutional symptoms and biochemical evidence of biliary tract obstruction. By abdominal sonogram and CT scan, a mass around the head of pancreas and periportal area was detected. The ERCP showed fistula connected proximal common bile duct to lymph node. The patient underwent laparotomy and recognized tuberculous adenitis of periportal lymph node which caused biliary tract obstruction with fistula.
