OBJECTIVES: This study was carried out to evaluate the effects of industrial noise on blood pressure and heart rate. METHODS: Resting blood pressure, hearing loss, and general characteristics of the 102 subjects who were engaged in a factory in Pusan were measured from March to June for two years, in 1998 and 1999. With noise dosimeter, noise exposure level was measured from 8 A.M. to 4 P.M. Ambulatory blood pressure and heart rate were also measured every 30 minutes from 8 A.M. to 10 P. M. RESULTS: Controlling for age, smoking, and Quetelet's index, in subjects of under 40 years old exposed to higher than 85dBA, noise exposure and systolic blood pressure had a statistically significant correlation, and the same result was obtained in all subjects. The daily variability of ambulatory blood pressure and heart rate were observed in older than 40 years old group, but only heart rate in under 40 years old. CONCLUSIONS: The blood pressure and heart rate would be elevated when the workers exposed to noise. And in under 40 years old, the systolic blood pressure was elevated to the workers exposed to higher than 85dBA.

There has not been any report on massive air-containing liver abscess in diabetic patients, although emphysematous cholecystitis or pyelonephritis is a well-known complication in them. Authors report two cases of emphysematous liver abscess in diabetic patient, which showed typical findings of massive air-containing hepatic abscess on ultrasonography and computed tomography, but very poor progrosis in spite of immediate and successful percutanoeus drainage procedure.

The term “non-ossifying fibroma of bone” was introduced by Jaffe and Lichenstein in 1942 to describe a distinctive benign lesion occuring near the ends of the long bones in young people, and the lesion was subsequently described by Hatcher as a developmental defect rather than a true tumor. This lesion was presented as a clear-cut entity on the basis of pathological, clinical and roentgenographic manifestations. The diagnosis of non-ossifying fibroma was made by the histopathological findings of the curetted tissues. The authors have seen and studied 5 cases of non-ossifying fibroma from February 1976 to September 1981. The average duration of follow up was 2.2 years, with a range from 0.8 to 5 years, and the results of treatment were as follows: l. Of the five cases, two were associated with pathologic fractures. 2. The sites of the lesions in all cases were the long bones in the lower extremity. 3 In all cases, the complaints were of only a few days or weeks duration before admission to the hospital, and no cases were discovered incidentally by roentgenographic examination. 4. Good results were obtained by treatment with curettage and bone graft.

Inadequate pain management after total knee arthroplasty (TKA) impedes recovery, increases the risk of postoperative complications, and results in patient dissatisfaction. Although the preemptive use of multimodal measures is currently considered the principle of pain management after TKA, no gold standard pain management protocol has been established. Peripheral nerve blocks have been used as part of a contemporary multimodal approach to pain control after TKA. Femoral nerve block (FNB) has excellent postoperative analgesia and is now a commonly used analgesic modality for TKA pain control. However, FNB leads to quadriceps muscle weakness, which impairs early mobilization and increases the risk of postoperative falls. In this context, emerging evidence suggests that adductor canal block (ACB) facilitates postoperative rehabilitation compared with FNB because it primarily provides a sensory nerve block with sparing of quadriceps strength. However, whether ACB is more appropriate for contemporary pain management after TKA remains controversial. The objective of this study was to review and summarize recent studies regarding practical issues for ACB and comparisons of analgesic efficacy and functional recovery between ACB and FNB in patients who have undergone TKA.

BACKGROUND: It has been suggested that the incidence of tourniquet pain is less frequent in patients in whom bupivacaine has been employed for spinal anesthesia than in patients to whom tetracaine has been administrated. The current study was accomplished to compare the incidence of tourniquet pain in patients in whom 0.5% plain bupivacaine spinal anesthesia and 0.5% hyperbaric tetracaine spinal anesthesia were employed. METHODS: The incidence of tourniquet pain was evaluated in 40 patients having orthopaedic surgery of the lower extremities during spinal anesthesia using 15 mg of hyperbaric 0.5% tetracaine(group I) or 15 mg of a plain solution of 0.5% bupivacaine(group II). The drugs were administrated in a randomized fashion. We measured the maximal sensory spread of analgesia to pinprick test, the incidence of tourniquet pain, the sensory anesthesia to pinprick test at time of onset of tourniquet pain and the number of patient treated with IV injection of fentanyl to relieving tourniquet pain. RESULTS: The maximal sensory spread of analgesia mean was higher in patients given hyperbaric tetracaine (T8) than in patients given plain bupivacaine (T9). The incidence of tourniquet pain was significantly greater in patients given hyperbaric tetracaine (65%) than in patients given plain bupivacaine (15%). The incidence of analgesics injection for tourniquet pain was greater in patients given hyperbaric tetracaine (10%) than in patients given plain bupivacaine (none). CONCLUSIONS: In conclusion, the tourniquet pain in surgery of the lower extremities occurs less frequently when plain bupivacaine is employed for spinal anesthesia as compared to hyperbaric tetracaine.
