Ossification and calcification of the spinal ligaments frequently cause pressure upon the spinal cord andnerve roots. Authors reviewed 150 cases of C-spine CT, 80 cases of T-spine CT, and 725 cases of L-spine CT whichwere carried out a Pusan Natina University Hospital for 2 years from May 1983 to May 1985. We analysed 34 caseswhich showed ossification of posterior longitudinal ligament (OPLL) and ligamentum flavum (OLF) of these 955cases. The results are follows: 1. The male ot female ratio of spinal ligamentous ossification was 26:8. The 5thdecade group (24.41%) was the most prevalent age group. 4th decade(26.4%), 6th decade(23.52%), 7th decade(11.76),3rd decade (8.8%), and 8th decade(2.94%) in that order. 2. Of 955 cases of spine CT, the incidence of OPLL was 25cases(21.51%) and that of OLF was 10 ases(1.05%). 3. Regional incidence of spinal ligamentous ossification was asfollows. 1) In case of OPLL, cervical area was 19/150(12.67%) and lumbar area was 6/725 (0.83%). 2) In cases ofOLF, Thoracic area was 3/80(3.75%) and lumbar area was 8/725(1.10%). 4. The most frequent length of OPLL was 4body length (32%) and the most frequent locations are C4 and C5(68%). The types fo OPLL were 15 cases(60%) ofsegmental type, 8 cases(32%) of continuous type, and 2 cases(8%) of mixed type in that order. All segmental typeswere degree 1 or 2 and most continuous and mixed type (80%) were degree 2 or 3 dural sac effect. 5. The number ofinvolved interlaminar spaces in OLF was 1 to 5 interspaces and most of OLF were found at low thoracic and lumbararea. 6. There could be noted high correlation between the spinal ligamentous ossification and degenerative discdisease, The incidence of associated disc disease was 18/25(72%) in OPLL and 8/10(80%) in OLF.

The effects of resin on the respiratory health have been investigated in 309 workers from four iron and steel foundries and the results compared with those from 122 workers who were not significantly exposed to resin gas and silica dust at the same industries. Phenol-formaldehyde resin was used in the core making and molding processes and workers were exposed to their decomposition products as well as to silica dist containing particulates The subjects were grouped according to formaldehyde, dust and other gas exposures, and smoking habits were considered also in the analysis. Standardized respiratory symptom questionnaire was administered by trained interviewers. Chest radiograph, pulmonary function tests, and methacholine challenge tests were done. Environmental measurements at the breathing zone were carried out to determine levels of formaldehyde, respirable dust and total dust. Foundry workers had a higher prevalence of symptoms of chronic bronchitis with chronic phlegm and chronic cough when exposed to dust. Exposure to gas was significantly associated with lowered FEV1 and obstructive pulmonary function changes. Exposure to formaldehyde and phenol gas was associated with wheezing symptom among workers, but FEV1 changes after methacholine challenge were not significantly different among different exposure groups. When asthma was defined as the presence of bronchial hyperreactivity with more than 20% decrease in FEV1 after methacholine challenge, 17 workers out of 222 tested had asthma. Fewer asthmatic workers were found among groups exposed to for maldehyde, gas and dust, which indicates a healthy worker effects in a cross-sectional study. The concentration of formaldehyde gas ranged from 0.24 to 0.43 ppm among studied foundries. The authors conclude that fornaldehyde and phenol gas from combust resin is probably the cause of asthmatic symptoms and also a selection force of those with higher bronchial reactivity away from exposures.

Intramural hematoma(IMH) and penetrating aortic ulcer have been increasingly recognized as causes of acute aortic pathology in addition to aortic dissection. The presence of the intimal tear and a flap traversing the aortic lumen is considered to be a most reliable differential point of aortic dissection and IMH. Transesophageal echocardiography(TEE) has become a valuable modality for the diagnosis, prognosis and management of acute aortic syndrome with the unique advantages of portability and the ability to obtain high-resolution real time images. Endovascular Stent-graft placement over the primary entry tear may be an alternative to open surgery because it can close the intimal tear, which leads to thrombosis of the false lumen, excluding flow through the intimal tear and redirecting aortic flow exclusively into the true lumen. We report 88 year-old male with aortic dissection in descending thoracic aorta, successfully treated with endovascular Stent-graft implantation, which was mimicking intramural hematoma by its appearance and subclinical intimal tear diagnosed exclusively by TEE against other imaging studies.

We performed temporary scleral buckles to treat the rhegmatogenous retinal detachment without traction by using intraorbtal balloon. Four eyes of four patients were operated from July 1994 to January 1995 and followed for at least 6 months. Balloon was inserted into the parabular space and left for one week. Cryopexy- or laser-induced adhesions were needed to make the attachments permanent. In all patients, retina reattached successfully without reopening of retinal break after the removal of the balloon. We suggest that intraorbital ballooning is a good choice of primary procedure for the retinal detachment with a single retinal break or group of breaks close together, because this is simple and inexpensive.

The aortic dissection is an acute aortic syndrome, caused by an intimal tear and subsequent splitting of the media by the pulsatile blood flow. Though there would be differences in the origin of aortic dissection and therapeutic modalities, the intermediate and long-term prognoses are poor. Endovascular Stent-graft implantation is a revolutionary technique in the treatment of aortic dissection. The endovascular stent grafting in aortic dissection is less invasive and feasible method and is an effective tool for closing the entry site and promoting clot formation, reducing the size of the false lumen. Therefore, endovascular Stent-graft implantation makes possible the desirable remodelling of aorta. We report 33 year-old male with aortic dissection in the thoracic aorta, which was treated with endovascular Stent-graft implantation. Over the favorable remodelling, his dissection was healed completely by the endovascular treatment using Stent-graft.
