Thirty three healthy young men and six dogs equipped with gastric fistulae were stimulated by noise of 100 to 120 phons emanating from a F-86F jet engine. The basal secretion of gastric juice in the dogs was little changed, but in human subjects the secretion of gastric juice was altered as follows; 30.3% of 33 subjects showed an increased acid output, 63.6% showed a decrease and the remaining showed no change. Furthermore, the basal resting secretion of those showing decreased acidity from noise exposure was higher than that of those showing increased acidity. Gastric motility was greatly inhibited by exposure to noise in both dogs and humans but the inhibition was more sensitive and more prolonged in humans. Rats fed synthetic diet were placed under conditions of repeated noise for either short or long periods and the occurrence of gastric ulcers by the procedure described by Shay et al was observed. The prevalence of ulcer lesions was increased and the severity of the lesion was enhanced in rats exposed to noise for either short or long periods. The above results indicate that the influences of air-craft noise were not remarkable, but the noise to a considerable degree, is responsible for the occurrence of gastric disorders in man. Sound fields surrounding air-craft engines are thought to be the cause of physical or mental disturbances experienced by persons at close range. Laird (1932) reported that 60 decibels of noise decreased the normal secretion of gastric juice in four of five human subjects who previously had been given an Ewald meal and also caused a decrease in the normal secretion of saliva by about 40 per cent. Previously Laird and Smith (1930) had observed that 80 to 90 decibels of noise caused a decrease in gastric motility in human beings. Vaughan and Van Liere (1940) reported a significant reduction in acid secretion in dogs with Pavlov pouches from a noise of l00 decibels and 2,000 frequency. However, noise frequency of 600 was ineffective. The present study was undertaken to determine in humans and animals whether digestive function or other disorders occurred readily with either single or repeated exposure to air-craft noise.

PURPOSE: To evaluate MRI findings of lateral lumbar disc herniations (LLDHs) and to determine whether those correlate with clinical symptoms. MATERIALS AND METHODS: The study included 105 patients with LLDHs that were diagnosed by MRI. The distribution and location of the LLDHs (foraminal, extraforaminal, and foraminal and extraforaminal), the displacement of adjacent nerves, and the detection rate of LLDHs from axial and sagittal images were reviewed retrospectively by two radiologists. 36 patients were included in evaluating whether location of LLDHs and displacement of adjacent nerve correlate with radiculopathy. RESULTS: The distributions of the LLDHs were 3.4% at L1-2, 14.4% at L2-3, 33% at L3-4, 33% at L4-5, and 16.9% at L5-S1. The locations were foraminal in 38.6% of cases, extraforaminal in 45.4% of cases, and foraminal and extraforaminal in 16% of cases. In addition, 77.3% of the diagnosed LLDH cases displaced the adjacent nerve. The detection rates of LLDHs in the axial and sagittal images were 100% and 77.3%, respectively. In 36 patients, 47.4% had radiculopathy related to LLDHs. Location of LLDHs and displacement of adjacent nerve had no statistically significant difference between patients with or without radiculopathy. CONCLUSION: MRI is an effective method for evaluating the location of LLDHs and their influence on adjacent nerves. The axial image is more important than the sagittal image in diagnosing LLDHs. The location of LLDHs and the displacement of adjacent nerve were not found to be related to radiculopathy.

Factitious fever has been a rare cause of fever of unknown origin. We herein report a case of a young soldier, who presented with persistent fever of unusual pattern and bullae on both palms. After numerous investigations had excluded organic diseases, factitious fever was diagnosed with measurement of the freshly voided urine temperatures and body temperatures while directly observed. Biopsy of skin lesions revealed friction blister. Early recognition of this cause of fever is needed to avoid the unnecessary investigation and prolonged hospitalization.

PURPOSE: We wanted to retrospectively determine the accuracy of an ultrasonographic diagnosis of superficial soft tissue masses in the extremities by using the histologic results as the reference standard. MATERIALS AND METHODS: From January 2005 to June 2010, 154 patients with soft tissue masses in the extremities and who underwent ultrasonographic evaluation followed by biopsy or resection were retrospectively evaluated. The ultrasonographic and histologic diagnoses of the soft tissue masses were lipoma, ganglion cyst, hemangioma, neurogenic tumor, giant cell tumor of the tendon sheath, epidermoid cyst, fibroma, glomus tumor, Baker's cyst and neurofibromatosis. RESULTS: Out of 154 patients, 114 (74%) patients showed concordance between the histologic diagnosis and the ultrasonographic diagnosis, and the remaining 40 (26%) patients did not. The diagnostic accuracy of each soft tissue mass was 95% for lipoma, 83% for ganglion cyst, 75% for hemangioma, 72% for neurogenic tumor, 50% for giant cell tumor of the tendon sheath, 43% for epidermoid cyst, 33% for fibroma and 100% each for glomus tumor, fibromatosis and Baker's cyst. Aside from these tumors, there were also sarcoma, malignant melanoma, elastofibroma, Kimura disease and pilomatricoma. Among the cases that showed discordance between the histologic diagnosis and the ultrasonographic diagnosis, three of them were notable; pilomatricoma being misdiagnosed as dermatofibroma protuberans, angiolipoma being misdiagnosed as vascular leiomyoma and malignant fibrous histiocytoma being misdiagnosed as a malignant soft tissue mass. CONCLUSION: The accuracy of an ultrasonographic diagnosis for soft tissue masses in the extremities varies greatly according to each type of mass. Lipoma, ganglion cyst, hemangioma, glomus tumor, neurogenic tumor and Baker's cyst showed a relatively high rate of concordance between the ultrasonographic diagnosis and the histologic diagnosis, but epidermoid cyst and fibroma showed a relatively lower rate of concordance.

PURPOSE: To compare lumbar disc changes between initial lumbar spine (L-spine) MRI and follow-up (f/u) MRI that were performed due to recurred backaches. MATERIALS AND METHODS: A total 50 patients who had undergone f/u L-spine MRI were retrospectively reviewed. Five discs (L1-S1) were surveyed in each f/u MRI. Lumbar disc changes were defined as no change, aggravations, or improvements compared to initial disc states. These states were defined on the basis of morphologic status and disc levels. RESULTS: In a total of 250 discs in 50 patients, 31 discs (12.4%) showed morphologic changes of disc lesions, whereas 219 discs (87.6 %) showed no changes. Among the 31 disc lesions, 24 were aggravated and 7 were partially improved. And on the basis of disc status, initially abnormal discs revealed any morphologic changes of the degree of disc herniation. A total of 33.3% of the morphologic changes are noted in initially extruded discs. Fifteen morphologic changes of disc lesions were located at the L4-5 level. CONCLUSION: Our results suggest that correlations between lumbar disc herniations and back pain symptoms are limited, and that evaluations of extra disc lesions are required.

BACKGROUND: Hypopituitarism is associated with osteoporosis and osteopenia especially when hypogonadotropic hypogonadism is present. Despite hypopituitarism being an important cause of secondary osteoporosis, osteoporosis in patients receiving surgery for pituitary tumors in Korea has not been studied. In this study, we evaluated the effects of testosterone replacement therapy (TRT) on bone mineral density (BMD) in postoperative hypogonadal patients with pituitary tumors. METHODS: To examine the effect of TRT on BMD, we performed a retrospective observational study in 21 postoperative male patients who underwent pituitary tumor surgery between 2003 and 2012 at the Ajou University Hospital. Testosterone was replaced in postoperative hypogonadal patients by regular intramuscular injection, daily oral medication, or application of transdermal gel. BMD (g/cm2) measurements of central skeletal sites (lumbar spine, femoral neck, and total femur) were obtained using dual-energy X-ray absorptiometry (GE Lunar). For lumbar spine BMD, L1 to L4 values were chosen for analysis. Femur neck and total femur were also analyzed. RESULTS: During the follow-up period (mean, 56 months; range, 12 to 99 months) serum testosterone levels increased with the administration of TRT (P=0.007). There was significant improvement (4.56%+/-9.81%) in the lumbar spine BMD compared to baseline BMD. There were no significant changes in the femur neck BMD or total femur BMD. We did not find any statistically significant relationships between changes in testosterone levels and BMD using Spearman correlation analysis. CONCLUSION: Our results indicated that TRT used in the postoperative period for hypogonadal pituitary tumor surgery patients may have beneficial effects on the BMD of the spine.
