Nicotine is a liquid alkaloid present in tobacco leaves at a 1~6% concentration. Green tobacco sickness is an occupational illness caused by absorption of nicotine through skin exposed to wet tobacco leaves. It occurs throughout the world in tobacco-growing areas. The almost universal symptoms of weakness, nausea, vomiting, diarrhea, and dizziness may be confused with pesticide poisoning or heat stress illness. Since its recognition in the 1970s, green tobacco sickness is self-limited, usually lasting 1 to 2 days. There is no antidote, so treatment is supportive (for example, intravenous fluids for hypotension, antiemetics). The diagnosis can beconfirmed by measuring the nicotine concentration in the serum or urine, but its half-life is only 3~4 hours. Cotinine, the major nicotine metabolite, has a half-life of 36 hours, and thus is more useful. Young workers may be at higher risk for green tobacco sickness. Tobacco use is thought to offer weak protection by inducing tolerance. Handling tobacco that is wet from rain or dew increase the risk of green tobacco sickness. Repeated daily exposure over more than a week may also increase the risk. Green tobacco sickness is preventable by use of protective clothing and by avoiding skin contact with wet tobacco. When clothing becomes wet from environmental dampness or sweating, it should be changed to maintain an effective barrier. The best treatment is avoidance of poisoning : in addition to wearing gloves, long pants and a full shirt, workers picking or handling tobacco leaves should clean their hands frequently.

The first case of karoshi was reported in 1969 with the death from a stroke of a 29-year-old, married male worker in the shipping department of Japan's largest newspaper company. It was initially called occupational sudden death. Shift work and an increased work load, together with excessive overwork in spite of ill health just before the stroke, were finally recognized as the occupational causes of death. It took five years for the family to receive compensation. In 1982, the first book entitled "Karoshi" was published by three physicians. This was the origin of the term karoshi. Karoshi is not a pure medical term but a sociomedical term. Karoshi-deaths were associated with long working hours, shift work, stress, and irregular work schedules. In Korea, karoshi was introduced in 1990. The cases with cerebral hemorrhage, subarachnoid cerebral hemorrhage, cerebral infarction, hypertensive encephalopathy, angina pectoris, myocardial infarction, and dissecting aneurysm would be compensated as occupational diseases if the patients had overworked. Now, the magnitude and kinds of diseases of karoshi is being extended. Medical doctors must understand the karoshi and make efforts to make the victims of karoshi be compensated. The evidence that overwork causes sudden death is still incomplete. More studies are needed to clarify the causal relationship. To prevent karoshi, the working hours should be shortened and health promotion programs for all workers should be encouraged.

This survey was conducted to find out demage done to the farmers by ;Agrochemicals in a rural area of Korea from January to October, 1980. Choon Sung Gun, Kang Won Province was the survey area and the 412 males were surveyed among all those that have sprayed agrochemicals. during 10 Months in 1980. Obtained results and findings from this survey are summarized as follows; 1. The total spray days of 413 males were 3,114 days and avarage spray days per person were 7.54 days. Also avarage spray hours per person were 4.7 hours. 2. The incidence rate per 100 persons of self-recognized skin manifestation was 12.6 persons and incidence rate per spray day was 2.7 percent. The incidence rate per 1Q0 persons of self-recognized intoxication was 23.0 persons and incidence rate per spray day was 3.6 percent. 3. In cases where mask was not used, when it was syrayed in hot weather, when stronger solution was used, the results were higher percentage in self-recognized intoxication (P<0.01). 4. The symptoms of self-recognized intoxication were headache (55.8%), dizziness (46.9%),. nausea (17.7%), fatigue (17.0%), and vomiting (17.0;%). 5. Number of intoxication per 100 used standardized unit by agrochemicals was parathion (93.8 spells), sumithion (91.8 spells) and folithion (66.7 spells). 6. Treatment was done by health facility utilization (27 cases), visits to drug store (13 cases) and visits to health center (7 cases).

The evaluation of posterior cruciate ligament injury of the knee should be objective. Then stress machine, Gonylaxometer, knee ligament arthrometer (K-T 1000) and Genucome were introduced recently, but they have many problems such as soft tissue error, expensiveness and low popularity. Authors modified the radiological assessment of anterior cruciate ligament injury, reported by Hooper(1986), and applied to the evaluation of posterior cruciate ligament injury. The patient was positioned supine with the one side of leg held on a support so that the knee was flexed approximately 45°to 60°. The thigh was unsupported and a weight(0.9 Kg to 4.5 Kg with increment of 0.9 Kg) was placed on the anterior leg (just distal to the patellar tendon) and lateral view had been taken in this stressed position. Same procedure was done on the other side and the posterior displacement of both knees were compaired. The differences of posterior displacement between both knees of 50 normal adults were studied and 9 cases of posterior cruciate ligament injury were studied, too. The following results were obtained. 1. The difference of posterior displacement could be measured objectively and it is useful for the diagnosis of posterior cruciate ligament injury and the objective evaluation after conservative or operative treatment of posterior cruciate ligament injury patient. 2. The differences of posterior displacement between both knees of 50 normal adults were ranged from 0 to 3 mm with a mean of from 0.88 ±0.87mm to 1.14 ±0.94mm. 3. The differences of posterior displacement between injured knee and normal knee of posterior cruciate ligament injury patient were more than 6mm in 9 patients. 4. The radiological method was inexpensive and easy to perform.

31 cases of the trochanteric fractures were treated at the Department of Orthopedic Surgery, Chosun University Hospital, from Jan. 1975 to Dec. 1978 and the following results were obtained. 1. The sex ratio was 3:2 (male to female). 18 cases were in man, with the peak age at the 4th decade and 5th decade and 13 cases were in woman over the 6th decade. 2. The most common causes of the trochanteric fractures were traffic accident or fall in man and slipping in woman. 3. The features of the trochanteric fractures were mostly unstable type (60%) and 16 cases in the right hip (52%) and 15 cases in the left hip (48%). 4. Dimon-Hughston method and Wayne-Country method were used to the unstable fractures and anatomical reduction to the stable fracture was maintained by inserting the S-P nail, Jewett nail and Mclaughlin nail. 5. Post-operative cast immobilization was applled until clinical union was oftained on the fracture site and early weight bearlng was carried out for the acceleration of the bony union. 6. Complications were found in 50% of the group treated by conservative method, while it occurred in 21.7% of the group treated surgically.

Most studies on the pathophysiology, natural history, diagnosis by imaging and outcomes after operative or nonoperative treatment of rotator cuff tear have focused on those of full-thickness tears, resulting in limited knowledge of partial-thickness rotator cuff tears. However, a partial-thickness tear of the rotator cuff is a common disorder and can be the cause of persistent pain and dysfunction of the shoulder joint in the affected patients. Recent updates in the literatures shows that the partial-thickness tears are not merely mild form of full-thickness tears. Over the last decades, an improved knowledge of pathophysiology and surgical techniques of partial-thickness tears has led to more understanding of the significance of this tear and better outcomes. In this review, we discuss the current concept of management for partial-thickness tears in terms of the pathogenesis, natural history, nonoperative treatment, and surgical outcomes associated with the commonly used repair techniques.
