PURPOSE: Congenital anomalies are known as a major cause of neonatal death with prematurity and birth injuries. We surveyed the incidence of congenital anomalies among livebirths and stillbirths delivered at our hospital, and detected in neonatal and postneonatal period. METHODS: The statistical study was done about congenital anomalies among 9,569 deliveries (9,438 livebirths and 131 stillbirths) at Ulsan University Hospital during the periods of 5 years from Jan 1992 to Dec 1996. We reviewed delivery and newborn record, OPD chart, admission chart retrospectively. We investigated the incidence of congenital anomaly according to each year, period, outcome of delivery, sex, birth weight, gestational age, maternal age, Apgar score, multiple pregnancy, and each system. RESULTS: 1) The overall incidence of congenital anomalies was 5.0% (481 cases) among 9,569 deliveries. The annual incidence was 4.5% in 1992, 5.1% in 1993, 5.2% in 1994, 5.8% in 1995, 4.7% in 1996. 2) The incidence of congenital anomalies detected in neonatal period was 3.5% (333 cases) and 1.5% (148 cases) in postneonatal periods. 3) The incidence of congenital anomalies was 4.9% among live births and 9.2% among stillbirths. 4) The incidence of congenital anomalies was 5.3% in male and 4.7% in female. 5) The incidence of congenital anomalies among the babies, below 2,500g of birth weight was 7.7%, between 2,500g and 3,999g was 4.7%, and over 4,000g was 6.8N. 6) The incidence of congenital anomalies among the babies, below 32 weeks of gestational age was 12.9%, between 32 weeks and 36 weeks was 7.4%, between 37 weeks and 41 weeks was 4.7%, and over 42 weeks was 5.1%. 7) The babies born to mothers younger than 20 years of age have anomalies in 7.1%, mother between 20 years of age and 35 years of age in 5.0%, and older than 35 years of age in 6.5%. 8) The incidence of congenital anomalies according to Apgar score among live births between 0 and 3 was 9.8%, between 4 and 6 was 6.0%, and between 7 and 10 was 5.0%. 9) The incidence of congenital anomalies according to multiple pregnancy was 8.6%. 10)The systems of congenital anomalies in order of incidence were as follows; The digestive system (25.6%), the cardiovascular system (22.1%), the genitourinary system (18.9%), the musculoskeletal system (15.5%), the skin and soft tissue (11.7%), the central nervous system (1.6%), the respiratory system (l%), the others (3.6%). CONCLUSIONS: Regular examination and screening on congenital anomaly is required from newborn period to infant and childhood. In view of these considerations, the incidence of congenital anomaly may be increased more than the past reports because of development of recent diagnostic techniques.

The bond failure of resin teeth to denture base resin is one of the failure in prosthodontic treatment. The purpose of this study was to evaluate the bond strength of artificial resin teeth to the denture base resins. Specimens were made with heat curing acrylic resins (Vertex Rs, Lucitone 199) and artificial resin teeth (Tiger, Trubyte biotone, Endura, Orthosit, Trubyte bioform IPN) and the bond strength were measured with testing machine (Zwick, Germany) and the mode of bond failure were observed. The results were as follows; 1. The bond strength of Vertex Rs to artificial resin teeth was the highest in Trubyte biotone, and It was the lowest in Tiger and Trubyte bioform IPN 2. The bond strength of Lucitone 199 to artificial resin teeth were higher in Orthosit and Trubyte bioform IPN than in Tiger and Trubyte biotone. 3. The bond strength of Trubyte biotone to Vertex Rs was higher than to Lucitone 199 and that of the Trubyte bioform IPN to Lucitone 199 was higher than to Vertex Rs. 4. Nearly all bond failures of specimens occured cohesively within the resin teeth.

A putative polypeptide hormone identified as amylin[islet amyloid polypeptide] is synthesized and co-localized with insulin in B cells of pancreatic islets in several animal species including man. However, there is growing evidence that somatostatin cells are also expressed and contained amylin in the pancreatic islets of the rat The aim of the present study was to investigate the immunocytochemical expression of the amylin within the endocrine pancreas of the man, rabbit and guinea pig, with special reference to the possible ability of islet cells other than insulin cells to synthesize amylin. For this purpose serial sections of the pancreatic islets were stainedimmunocytochemically using anti-amylin, anti-insulin, anti-glucagon, anti-somatostatin antisera. In serial sections of pancreatic islets of the man and rabbit, it was shown that amylin immunoreactivity occurred in insulin-reactive B cells predominantly located in interior of the islets. In contrast, amylin immunoreacivity appeared in glucagon-reactive A cells peripherally located in the islets of the guinea pig. These results suggest that in both the man and rabbit, amylin is synthesized by B cells for subsequent co-secretion with insulin, and that in guinea pig, amylin is synthesized by A cells for co-secretion with glucagon. It thus appears that amylin release may be mediated by different secretory mechanisms according to animal species.

The Dichloromethane(methylene chloride) is a highly volatile liquid used as a solvent, extraction medium, and paint remover. The most significant route of intoxication to dichloromethane is generally inhalation at work site or home, but ingestion is rare. The main toxicological harvard insults from in vivo conversion of dichloromethane to carbon monoxide. We present a case of dichloromethane intoxication following ingestion. A 71 years old male patient ingested 60-70cc of dichloromethane was brought to emergency department after stomach washout via nasogastric tube at other hospital. On arrival at emergency department(approximately 19 hours after ingestion), he was stuporous with a blood pressure 140/90mmHg, heart rate of 92 beats/min, dyspneic, respiratory rate of 24/min and body temperature 36.8 degrees C. His Pupils were isocoric, miotic, and sluggishly reactive. There were mucosal bums and significant secretion in oral cavity. On auscultation, breathing sound was coarse without role on both lung field. The COHb levels were 6.3%at 32 hours after ingestion and normalized to 0.6%at 44 hours after ingestion. Patient was transfered to intensive care unit and supportive care was started with 100% oxygen. On ingestion 4th day, chest X-ray showed pulmonary edema and acute respiratory distress syndrome developed. Patient regained the consciousness on the 11th day. On the 30th day, respiratory function improved and the ventilator was removed. Alveolitis and mild pulmonary fibrosis developed and mild dyspnea was continued. On the 36th day, gastroscopic examinations showed ulceration of esophagus and stomach. On the 76th day, patient was discharged after pulmonary rehabilitation.

This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

Pulmonary endometriosis is a rare disease which is characterized by hemoptysis during menstruation (catamenial hemoptysis). We report a case of pulmonary endometriosis in a 33-year-old housewife. She has had regular menses with moderate flow and minimal dysmenorrhea. She had undergone curettage in May 1995 for artificial abortion. In July 1995, she experienced the first episode of hemoptysis. A chest CT scan revealed a 2.0 1.0 cm sized ill-defined soft tissue density in the periphery of anterior segment of the left upper lobe with a surrounding irregular ground-glass opacity. A left upper lobectomy was done under the diagnosis of pulmonary endometriosis. Cut section of the resected lung showed a round red-brownish solid lesion, measuring 2.0x1.0cm in cross. Microscopically a focus of the endometrial tissue, which was composed of endometrial glands and stroma, was found in the lung parenchyme and many hemosiderin laden macrophages were seen in the surrounding alveoli. The postoperative course was favorable with no further episodes of hemoptysis.
