Purpose:
To evaluate the potential of incorporating respiratory muscle strength, specifically maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP), along with traditional sarcopenia screening measures such as hand grip strength (HGS) and skeletal muscle mass index (SMI), to identify sarcopenia in older men.
Materials and Methods:
A retrospective analysis was conducted involving male patients aged 65 years and older who underwent measurements of respiratory muscle strength, HGS, and muscle mass at a general hospital in Korea from July 2016 to May 2022. Statistical analysis utilized independent t-tests and receiver operating characteristic (ROC) curves to assess the sensitivity and specificity of MIP, MEP, HGS, and SMI in sarcopenia screening. The cut-off values for sarcopenia screening were determined based on the area under the ROC curve (AUC).
Results:
The analysis of 282 study participants revealed the following cut-off values for sarcopenia based on the AUC: for MIP, the cut-off value was 65.50 cmH2O (AUC=0.70, sensitivity: 0.63, specificity: 0.61), while for MEP, it was 84.50 cmH2O (AUC=0.74, sensitivity: 0.66, specificity: 0.68).
Conclusions
This study showed the utility of respiratory muscle strength in screening for sarcopenia among older men. We suggest the screening cut-off values as 65.50 cmH2O for MIP and 84.50 cmH2O for MEP. Even when HGS and SMI measurements are not feasible, sarcopenia can be reasonably predicted based on respiratory muscle strength.

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

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.

Congenital agenesis, aplasia or hypoplasia of the internal carotid artery is rare vascular disease and usually combine with intracranial aneurysm, subarachnoid hemorrhage, or intracerebral hemorrhage. We report a case of bilateral congenital hypoplasia of internal carotid artery in a 36 year-old woman presented with semicomatose mentality. The brain computed tomography(CT) revealed intracerebral hemorrhage with intraventricular hemorrhage, and cerebral angiography showed hypoplasia of bilateral internal carotid artery without narrowing of the bony carotid canal on the temporal bone CT.

BACKGROUND: Currently the most common treatment modality of refractory ascites in patients with liver cirrhosis was large volume paracentesis, but this procedure usually needed albumin infusion and occasionally developed unwanted complications. By reason of albumin shortage in Korea and occasional unfavorable complications, we studied the usefulness of dialytic ultrafiltration as an another treatment modality of refractory ascites. METHODS: Dialytic ultrafiltration was done in 10 patients (total 48 times) with liver cirrhosis or hepatocellular carcinoma. Two drainage conduit (via 16 gauge angio-catheter) of input and output were made by puncture of patient's right and left lower quadrant abdomen. The initial ultrafiltration rate of dialyser was 250mL/min. Ascitic fluid was removed continuously until the filtration rate down at 50mL/min. After ultrafiltration, ascitic fluid contained concentrated albumin and large molecules was reinfused via input conduit. Pre-treatment and post-treatment level of blood chemistry, plasma renin concentration, aldosterone, and electrolytes in serum; total protein and albumin in ascites were measured. During the ultrafiltration, we closely observed the change of blood pressure, heart rates and mental status. RESULTS: The mean ultrafiltration time was 231+/-28min, ultrafiltrated volume was 5.15+/-1.41 L. During dialytic ultrafiltration, patient's blood pressure and heart rate were stable and there was no change of mental status. After dialytic ultrafiltration, blood urea nitrogen level significantly decreased from 30.5+/-23.7mg/dL to 25.7+/-20.2mg/dL; serum aldosterone level decreased from 807.3+/-301.1pg/ml to 431.1+/-187.2pg/ml in serum (P<0.01). The albumin level in the ascitic fluid significantly increased from 0.67+/-0.28g/dL to 1.90+/-1.16g/dL (P<0.01). Plasma renin concentration level tend to decreased (P=0.06). The patient's serum total protein, albumin, electrolytes, and creatinine were not changed. Complications of dialytic ultrafiltration were peritonitis (one case) and hypotension (one case). But these unwanted complications were readily managed by adequate antibiotics and intravenous fluid therapy. CONCLUSION: The dialytic ultrafiltration can be used effectively without albumin infusion in the treatment of refrartory ascites in patients with advanced liver cirrhosis.

Meckel's diverticulum is an embryologic derivative of the omphalomesenteric duct and the most commonly encountered congenital anomaly of the gastrointestinal tract, affecting 1% to 2% of the general population. Although this prevalence is relatively low, Meckel's diverticulum is occasionally encountered as an incidental identification during abdominal exploration and can be associated with several life-threatening disease states, such as massive intestinal bleeding, intestinal obstruction, or on rare occasion, perforation. The management of a Meckel's diverticulum found incidentally on laparotomy is controversial because the rate of complications developing from the diverticulum remains uncertain. The data in this report are based on 18 cases of Meckel's diverticulum which were treated at the Department of Surgery, InJe University Sanggye Paik Hospital, during the 7 years between January 1990 and December 1996. The results are as follows: 1) The overall sex ratio of males to females was 5 : 1 and in the symptomatic group, the ratio was 6 : 1. 2) Ninety percent of the patients were under 40 years of age, and 56% were under 10. 3) The diverticula were located from 20 cm to 100 cm proximal to the ileocecal valve, and the average range was 53 cm from the ileocecal valve. Fifteen cases were located at the antimesenteric border, and 3 cases at the mesenteric border of the ileum. 4) The lengths of the diverticula ranged from 1cm to 6cm, and the diameters ranged from 0.5 cm to 4.5 cm. 5) Appendicitis and intestinal obstruction were the most frequent preoperative diagnoses in the symptomatic group. 6) The common complications were intestinal obstruction and inflammation. 7) Heterotopic tissues were found in three patients and all of them were ectopic gastric mucosa. 8) The treatment was a diverticulectomy or a segmental resection of the involved bowel. 9) Postoperative complications were found in three of the asymptomatic group: two early intestinal obstructions and one wound infection.
