STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

BACKGROUND: This study was aimed at defining the varying responses of porcine coronary artery(PCA) to various wavelengths of ultraviolet irradiation, and at relating them to the changes in cyclic GMP contents. METHODS: The ring preparations of PCA with intact or removed endothelium were irradiated with the ultraviolet or visible light of wavelengths(240-520mm) from xenon lamp of a spectrofluorometer, and the changes in vascular tension were recorder on polygraph. For cyclic GMP assay, rat thoracic aorta was frozen after irradiation and homogenated. The supernatant was extracted with water-saturated ether and the cyclic GMP contents were measured with radioimmunoassay. RESULTS: Ultraviolet irradiation relaxed the preparations(UVR-relaxation) in resting state and those precontracted by prostaglandin F2alpha, the maximal relaxation occurring at 410nm, and the magnitude depending on the duration of irradiation. The UVR-relaxation was not affected by removing the endothelium, while it was markedly potentiated by pretreatment with Bay K 8644. The Bay K 8644-induced potentiation of UVR-relaxation was abolished by hemoglobin and slightly reduced by wrapping the rings with aluminum foil. Cyclic GMP contents in the increase was markedly potentiated by pretreatment with Bay K 8644. CONCLUSION: The observations suggest that UVR-relaxation in procine coronary artery is caused by activating the nitric oxide-cyclic GMP system, which is most sensitively activated by UVR of 410nm and that its potentiation induced by Bay K 8644 may be related nitrous substance released from the agent upon UVR.

In adenomatous polyposis coli there are many colonic and extracolonic manifestations, and various combinations of these induce different clinical presentations and syndromes. We experienced a unique case of adenomatous polyposis of the large intestine and stomach in a 39-year-old man. In the colon, small cell neuroendocrine carcinoma rather than adenocarcinoma had developed, which did not contain adenomatous or carcinomatous foci. The adenomatous polyps in the colon were all small and sessile with no cancerous or precancerous change two years after the resection of the symptomatic gastric adenomas, even though the gastric adenomas were larger and showed dysplastic change. We think this case is another variant of adenomatous polyposis syndrome.

PURPOSE: To determine the plain film findings of acute neuropathic joint in diabetic foot. MATERIALS AND METHODS: Acute neuropathic joint in diabetic foot was considered when fragmentation of the articular ends of bone and subluxation of the affected joint developed within eight weeks after clinical onset of diabetic gangrene. Eight toes of six diabetics were satisfactory to our criteria. We analyzed plain radiographic findings of the affected joint and soft tissue, interval changes in follow-up radiographs, and deformities after healing. RESULTS: The time interval between clinical onset of gangrene and bone destruction ranged from 2 weeks to 4 weeks(mean 2.6 weeks). Plain radiographs showed fragmentation of the articular ends, subluxation, and soft tissue swelling of the metatarsophalangeal joint or interphalangeal joint. The significant feature of these patients was rapid progression of the lesions. Clinically, all patients had diabetic gangrene in affected toes, however, there was no evidence of osteomyelitis in our series. Amputation was done in 2 cases, and lesions in 3 of the remaining 4 cases were repaired spontaneously with regression of gangrene, leaving radiological residua such as pointed-end, tapered-end, and ball and socket deformity. CONCLUSION: Rapid disorganization of the joint with associated evidence of soft tissue gangrene in plain radiograph is believed to be valuable for the diagnosis of diabetic osteoarthropathy.

Bone injuries of the extremities can be found in 0.2-2% of all living newborns. The most common location of the fracture was clavicle, and followed by humerus, femur in orders. Fractures of the femur are relatively rare. Authors have analyzed 9 cases of the femoral shaft fractures in the newborns, treated at Severence Hospital from January 1985 to March 1992. Seven cases were born by Cesarean section, two cases were by normal spontaneous vaginal delivery. Vertex presentation were three cases, breech presentation were five cases, and transverse presentation was one case. The mean birth weight was 2.93kg and four cases were born in prematurity. The location of fracture were seven cases in proximal shaft, one case in mid shaft, and one case in distal shaft. The type of fracture were all spiral fracture except two fractures. Five cases were treated by splint and 4 cases were treated by traction method. No further immobilization was needed for 8 cases but two weeks long leg cast after splint was applied for one case. Two cases of complication were noted. Skin necrosis developed due to the traction to the popliteal fossa and minimal anterior angulation of femora, and no functional deficit were found, but bony protrusion of proximal femora were palpated.

10.Approaches to Consciousness Assessment in Neurocritically Ill Patients
Journal of the Korean Neurological Association 2024;42(2):107-115
The majority of neurocritically ill patients have disorders of consciousness. Both level and content of consciousness should be assessed repeatedly throughout the course of patient care. In this review, we describe the definition and diagnostic criteria for disorders of consciousness, and the neurological examination and standardized neurobehavioral assessment tools as methods of assessing consciousness. Next, we will discuss neurophysiological and neuroimaging tests as tools for assessing consciousness: automated quantitative pupillometry, electroencephalogram, evoked potentials, brain imaging, functional near-infrared spectroscopy, and biomarkers. We discuss the clinical utility of each assessment tool and the importance of a multimodal approach in the diagnosis, treatment, and prognostication of disorders of consciousness.
