We investigated the 1,004 workers who worked in a automobile factory to study the epidemiologic characterist of dermatoses due to cutting oils. Among the workers, 667(66.4%) answered the questionnaire. They are belong to 5 departments of the factory-the Engine-Work(86), Power train Assembly(17). We measured the oil mist concentration in air of the departments and examined the workers who had dermatologic symptoms. The results were follows; 1) Oil mist concentration; Of all measured points(52), 9 points(17.2%) exceeded 5mg/m3-the time-weighed PEL- and one department had a upper confidence limit(95%) higher than 5mg/m3. 2) Dermatologists examined 213 workers. 172 of them complained any skin symptoms at that time-itching(32.5%), papule(21.6%), scale(15.7%), vesicle(12.5%) in order. The abnormal skin site found by dermatologist were palm(29.3%), finger & nail(24.6%), forearm(16.2%), back of hand(8.4%) in order. 3) As the result of physical examination, we found that 160 workers had skin diseases. Contact dermatitis was the most common; 69 workers had contact dermatitis alone(43.1%), 11 had contact dermatitis with acne(6.9%), 10 had contact dermatitis with folliculitis(6.3%), 1 had contact dermatitis with acne & folliculitis, and 1 had contact dermatitis with abnormal pigmentation. Others were folliculitis(9 workers, 5.6%), acne(8, 5.0%), folliculitis & acne(2, 1.2%), keratosis(1, 0.6%), abnormal pigmentation(1, 0.6%), and non-specific hand eczema(47, 29.3%). 4) The prevalence of any skin diseases was 34.0 per 100 in cutting oil users, and 13.3 per 100 in non-users. Especially, the prevalence of contact dermatitis was 23.0 per 100 in cutting oil users and 4.3 per 100 in non-users. 5) We tried patch test(standard series, oil series, organic solvents) on 49 patients to differentiate allergic contact dermatitis from irritant contact dermatitis and found 20 were positive. 6) In a multivariate analysis(independent=age, tenure, kinds of cutting oil), the risk of skin diseases was higher in the water-based cutting oil user and both oil user than non-user or neat oil user(odds ratio were 2.16 and 2.78, respectively). And the risk of contact dermatitis was much higher at the same groups(odds ratio were 5.16 and 6.82, respectively).

There are many procedures for treatment of injuries of acromioclavicular separation but there are still con- roversies concerning the best management of these injuries. With this in mind, we treated surgically 22 cases of acromioclavicular separation of which 3 cases were old type 2 and 19 cases were type 3 in the department of orthopaedic surgery, Eul Ji General Hospital from March 1977 to darch 1982. The results were as follows: l. Of 22 cases, 21 cases (95.5%) were male with peak incidence in the 3rd and 5th decades (90.9%). 2. The most common causes of the injuries were traffic accidents (63.6%) and followed by falling from height (22.7%). 3. The diagnosis in type 2 and type 3 injuries is based on the clavicular displacement and instability at the acromioclavicular joint. 4. Operative treatment consists of Weaver and Dunn method (54.5%), modified Phemister method (18.2%), Neviaser method (13.0%), Stewart method (9.1%) and modified Henry method (4.5%). 5. The operative procedure in old type 2 and typc 3 injuries is good treatment of acromioclavicular separation.

This investigation was undertaken to know how soft tissue facial profile could be changed with age. The 3 serial lateral cephalometric roentgenograms of the twenty nine boys and twenty six girls between 9 and 13 years of age were studied and the findings seemed to warrant the following conclusions. 1. The author made the tables of means, standard deviations in each item, sex, age. 2. Soft tissue facial angle, soft tissue facial convexity including the nose tended to increase, but others tended to remain relatively stable. 3. Facial soft tissue thickness increased with age and the growth of facial soft tissue in the middle region (point A, LS, LI) was greater than others in the facial region. 4. In the soft tissue vertical proportions, G1'-Sn/Sn-Me' was 1.1, Sn-St/St-Me' was 0.51:1, Sn-LI/LI-Me' was 0.82:1 and those were stable with age.

PURPOSE: Peritoneal seeding is the most common type of metastasis and recurrence in gastric cancer. Recently, some studies have reported the benefits of a noncurative gastrectomy for greatly advanced gastric cancer; nevertheless, there are many controversies. This study was performed to investigate the survival benefit of a noncurative gastrectomy for patients with greatly advanced gastric cancer with peritoneal seeding. METHODS: We retrospectively analyzed 286 gastric-cancer patients who had received operations and who had been proven to have peritoneal seeding without liver metastasis or other hematogenous distant metastasis between January 1990 and December 1997 at the Department of General Surgery, College of Medicine, University of Ulsan. RESULTS: The distribution of the degree of peritoneal seeding was P1 in 84 cases (29.4%), P2 in 56 cases (19.6%), and P3 in 146 cases (51.0%). The duration of median follow-up was 9 months (range: 0.4-83.9 months). A noncurative gastrectomy was performed in 121 cases (42.3%); out of them, a total gastrectomy was performed in 49 cases (40.5%), a distal gastrectomy in 70 cases (57.9%), and a proximal gastrectomy in 2 cases (1.6%). A noncurative gastrec tomy was done 51 of the P1 cases (60.7%), 23 of the P2 cases (41.1%), and 47 of the P3 cases (32.2%). D2 lymph-node dissection was performed in 168 cases (87.6%). Postoperative complications developed in 5 cases with a noncurative gastrectomy, and there was no operative mortality. The median survival times were 11.3 months in P1 cases, 10.5 months in P2 cases, and 6.6 months in P3 cases. The median survival times of noncurative gastrectomy, bypass, and expoloratory laparotomy cases were 11.5 months, 6.6 months, and 6.3 months, respectively; according to the degree of peritoneal seeding, they were 14.8 months, 7.1 months, and 5.3 months in P1 cases, 15.3 months, 8.2 months, and 12.5 months in P2 cases, and 7.6 months, 6.4 months, and 5.7 months in P3 cases, respectively. The difference in survival time between the resection and the nonresection groups had statistical significance regardless of the degree ofperitoneal seeding (p<0.05). In the multivariate analysis, the degree of peritoneal seeding (RR: 1.33) and gastric resection (RR: 1.52) were proven to be significant prognostic factors. CONCLUSION: A noncurative gastrectomy might lengthen the survival time in advanced gastric-cancer patients with peritoneal seeding.

PURPOSE: This study was designed to investigate the significance of preoperative serum CA 19-9 level as a prognostic factor and postoperative serum CA 19-9 level as an indicator for recurrence in gastric adenocarcinoma patients. MATERIALS AND METHODS: 328 patients, who received curative resection of stomach for gastric cancer from 1989 to 1996 and followed up successfully, were analyzed retrospec- tively. Median follow-up period was 24 months (range: 11-38 months). The cut off level of serum CA 19-9 was 37 U/ml. The relationships between preoperative serum CA 19-9 status and prognostic parameters, recurrence and survival rate were analyzed. Multivariate analysis using Cox proportional hazards regression analysis was performed to evaluate as an independent prognostic factor. The relationship between postoperative serum CA 19-9 level and recurrence was investigated. RESULTS: Out of 328 cases, 29 cases (8.8%) showed elevated preoperative serum CA 19-9 level. The preoperative serum CA 19-9 level was correlated with the degree of depth of invasion and the status of lymph node metastasis (p<0.05). Patients with positive pre- operative serum CA 19-9 status showed higher incidence of recurrence (p<0.05) and poorer survival rate (p=0.00003) than patients with negative status. Preoperative serum CA 19-9 status (risk ratio: 3.4464, p=0.0039) revealed as an independent prognostic factor in multivariate analysis. Postoperative serum CA 19-9 status revealed as a useful predictor for recurrence in patients with positive preoperative serum CA 19-9 status. CONCLUSION: Preoperative serum CA 19-9 determination in patients with gastric cancer was valuable for predicting tumor progression and prognosis. Preoperative serum CA 19-9 status may be helpful to predict recurrence earlier than other diagnostic tools, especially in the patients with positive preoperative serum CA 19-9 status.

PURPOSE: CEA, CA19-9, and CA72-4 are the most commonly used tumor markers in stomach cancer. This clinical study was performed to evaluate the diagnostic value of these tumor markers in stomach cancer patients. MATERIALS AND METHODS: A retrospective analysis of 170 stomach cancer patients who had undergone curative gastrectomy between January 1991 and December 1996 at the Department of Surgery was performed. The preoperative and postoperative serum levels of these tumor markers were measured in 170 patients. RESULTS: The preoperative positive cases were 28 cases (16%) in CEA, 15 (9%) in CA19-9, and 24 (14%) in CA72-4. The postoperative positive cases among 48 recurrences were 21 cases (44%) in CEA, 10 (21%) in CA19-9, and 10 (21%) in CA72-4. The combination of CEA with CA19-9 or CA72-4 had higher positivity rate (58%) than single tumor marker. The highest positivity rate was found in CEA at recurrences of anastomotic site, in CA19-9 at recurrences of lymph node, in CA72-4 at peritoneal seeding and distant metastasis. In multivariate analysis, these tumor markers were not independent prognostic factors. CONCLUSION: CEA, CA19-9, and CA72-4 have proved unhelpful in initial diagnosis of stomach cancer because of their low positivity rate. And the combination of 3 tumor markers was the useful method for raising positivity rate in diagnosis of recurrences.

BACKGROUND: Memory impairment results from various neurologic disorders. Among them, the memory loss associated with stroke is called amnesic stroke. Involved regions in the amnesic stroke are medial temporal lobe, thalamus, basal forebrain, retrosplenial region, and subcortical regions. Unilateral amnesic stroke is posterior cerebral artery territory including thalamus. Isolated infarction of hippocampal region has been rarely reported because hippocampus has dual blood supply from anterior choroidal cerebral artery and posterior cerebral artery. CASE REPORT: A 61-year old male with a history of diabetes for 6 years and hypertension for 13 years, was admitted with acute memory loss occurring 6 days before admission. He could not remember the exact date, place and recent events but could remember remote events about his personal and familial affairs. Brain MRI revealed an infarction in left hippocampal region and cerebral angiography showed multiple focal stenosis and luminal irregularity on left anterior choroidal, middle cerebral, basilar and both posterior cerebral arteries. COMMENTS: We report unilateral amnesic stroke only confined to left hippocampal region with literature review.

OBJECTIVES: This study was performed in order to assess the incidence of hypertension based on two-years follow-up of a rural hypertension-free cohort in Korea. METHODS: The study cohort comprised 2,580 subjects aged above 20 (1,107 men and 1,473 women) of Chung-Song County in Kyungpook Province judged to be hypertensive-free at the baseline examination in 1996. For each of two examinations in the two-year follow-up, those subjects free of hypertension were followed for the development of hypertension to the next examination one year (1997) and two years later (1998). The drop-out rate was 24.7% in men and 19.6% in women. Hypertension was defined as follows 1) above mild hypertension as a SBP above 140 mmHg or a DBP above 90 mmHg, 2) above moderate hypertension as a SBP above 160 mmHg or a DBP above 100 mmHg or when the participant reported having used antihypertensive medication after beginning this survey. RESULTS: The age-standardized incidence of above mild hypertension was 6 per 100 person years (PYS) in men and that of above moderate hypertension was 1.2. In women, the age-standardized rate for above mild hypertension was 5.7 and 1.5 for above mild and moderate hypertension, respectively. However, the rates of incidence as calculated by the risk method were 4.8% and 1.0% in men and 4.6%, 1.2% in women, respectively. In both genders, incidence was significantly associated with advancing age(p<0.01), In men, the incidences of above moderate hypertension by age group were 0.5 per 100 PYS aged 20-39, 0.7 aged 40-49, 1.7 aged 50-59, 3.6 aged 60-69, and 5.8 aged above 70(p<0.01). In women, those the incidence measured 0.6 per 100 PYS aged 20-39, 1.8 aged 40-49, 1.3 aged 50-59, 3.3 aged 60-69, and 5.6 aged above 70(p<0.01). After age 60, the incidence of hypertension increased rapidly. CONCLUSIONS: The incidence data of hypertension reported in this study may serve as a reference data for evaluating the impact of future public efforts in the primary prevention of hypertension in Korea.
