The temporomandibular joint arthrocentesis is indicated the `closed lock' due to anterior disc displacement without reduction. It can be easily carried out under local anesthesia with little complications. We performed arthrocentesis to the 24 patients, 9 patients who suffered from acute or chronic closed lock with anterior disc displacement, 2 patients from temporomandibular joint dysfunction related to systemic disease and 13 patients from joint dysfunction with pain. We present the common clinical aspect of arthrocentesis that operator can be easily faced with and possible modifications of this method.

To measure the birth registration rate and the validity of birth registration data in rural area, all of the 4,014 married women under 49 years of age who had not been sterilized in Gunwee county of Kyungpook province were followed by Myun health workers for 2 years from April 1, 1985 to March 31, 1987 and 766 births were detected. All of the birth registration records of Myun offices were reviewed on September 30, 1987 and 944 births which occurred within the above mentioned period were found. Actual birth date obtained by follow-up study were compared with the birth date on registration card. Among 766 births detected by follow-up study, 576 births(75.2%) which were reported within 6 months after birth were ascertained on the official registration records and 96 births(12.5%) were not found on the records although mother stated that the birth was registered. The registration rate within legal due date was 61.3% among 576 births detected by follow-up study and also ascertained on the official records. The registration rate within legal due date was lower in mothers under 20 years of age and above 35 years and in mothers who had only primary education. It was decreased as the birth order increased. The registration rate was higher in births occurred from October to March than births occurred from April to September. All of the births of 7 neonatal deaths were not reported. The registered birth date was consistent with the actual birth date in 78.0%. Birth date on record was earlier than the actual birth date in 6.8% and later in 15.3%. The consistency rate was lower in mothers above 35 years of age(54.5%), and in infants of 4th birth order and above(56.3%). The rate was increased as the maternal education level increased. The rate of boys was higher than that of girls. A higher percentage(17.4%) of infants born in March was registered with earlier date than the actual birth date and most of these registered birth dates were lunar calendar date. This might be related with the age for entering the primary school. The study findings revealed that the birth registration rate within legal due date and accuracy of report have been increased in recent years, but the infant mortality rate derived from the birth registration seems to be very inaccurate. It is suggested to let the medical personnel who delivered the baby report the birth by mail directly to the current address of parent while infants delivered at home without professional attendant may comply with the present registration system.

A pulmonary artery sling is a very rare congenital abnormality in which the left pulmonary artery rises from the posterior surface of the right pulmonary artery and then passes between the trachea and the esophagus, causing tracheal compression. It is associated with tracheo-bronchial abnormalities (50%) and cardiovascular abnormalities (30%). It may produce respiratory symptoms through the airway compression of the abnormal left pulmonary artery and congenital abnormalities associated with it. Because most (90%) pulmonary artery sling patients present symptoms during infancy, their condition is often diagnosed in the first year of life. However, a pulmonary artery sling is occasionally found in adults. It is usually asymptomatic and found incidentally. This is a very rare case of an asymptomatic pulmonary artery sling in an adult. A 38-year-old man presented symptoms of mild exertional dyspnea. His spiral computed tomography showed a pulmonary artery sling. He was discharged without specific treatment because his symptoms improved without specific treatment and might not have been associated with a pulmonary artery sling. We report an adult case of an asymptomatic pulmonary artery sling diagnosed via spiral computed tomography, accompanied by a literature review.

Paraquat intoxication is a fatal problem. Most of paraquat intoxications happen through oral administration. But there is no clinical data for parenteral paraquat intoxication, so we will describe its fatal progression and clinical course. A 52-year-old male injected paraquat solution on his thigh. Initial serum level of paraquat was 42.7 microgram/mL and urgent hemoperfusion was performed and his serum level of paraquat was reduced by 5.2 microgram/mL. But the patient expired due to respiratory failure and hypoxemia. Different from oral paraquat poisoning, serum level of the drug increases rapidly in intramuscular intoxication. So the paraquat in blood rapidly accumulates in tissue, especially lung parenchyme. We removed his paraquat in blood rapidly, but could not get rid of tissue concentration, so we lost him even with lowered serum paraquat level. Through this case, it is thought that the paraquat intoxication via intramuscular injection can make up a extremely poor prognosis even with very a little amount of paraquat.
