Oral cholecystography is one of the most relible and widely used x-ray examination which enables us to observe not only morphological features of the gallbladder (GB) but also its functioning state. It was disclosed that functional evaluation of the GB is mandatory to recognize such kinetic disorders of the viscus as acalculous cholecystitis or dyskinesia. For the purpose of functional evaluation, fat meal has been used traditionally. Recently, cholecystokinin(CCK) and ceruletide were introduced into clinical diagnosis of the GB, the usefulness of which we have confirmed. In the present study we have made an attempt at improving cholecystagogic effect of conventional fat meals(FM) such as whole mild and egg yolk by changing the posture of the examined from sitting up to right decubitus position after the ingestion of fat meal. The hypothesis involved in this study is that the presence of quantitatively more fat meal in the duodenum per unit time may result in more effective cholecystagogic action and such a setting would be created by enhancement of pyloric passage of fat meal by decubitus posturing. Clinical materials consisted of 280 normal oral GB series (136 males and 144 females) andthey were divided into 4 equally numbered groups of mild sitting and mild decubitus and egg sitting and eggdecubitus. Upon confirming satisfactory opacification of the GB 11 hours after the ingestion of 3g of sodiumipodate or iopanoci acid either 2 pieces of medium sized hen's egg yolk were given. The xaminess were then allowed either sitting up comfortably on a bench or lying down on the right flank on a couch. After the ingestion of fat mean, x ray was taken at the end of 30 minutes in all but the mild decubitus group in which x rays were taken serially at the end of 5, 15, 30 and 60 minutes. The frontal area of each opacified GB was measured by using aplanimeter and the contraction rate before and after fat meal stimulation was calculated by the following equation and delineation of the biliary tree was analyzed in each group. Contraction rate (%) = (1

PURPOSE: To compare the success rates, complications and cost effectiveness of extracorporeal shock wave lithotripsy (ESWL) and ureteroscopic lithotripsy (URS) using a Holmium: YAG laser to establish the more effective treatment for upper and mid ureter stones. MATERIALS AND METHODS: This retrospective study included 83 and 286 patients treated with URS and ESWL, respectively, for upper and mid ureter stones. URS was performed with a 7.5Fr semi-rigid ureterorenoscope and Holmium: YAG laser. ESWL was performed with Stonelith V.5 (PCK, Turkey). The stone sizes, success rates, postoperative complications and cost effectiveness were analyzed for each group. RESULTS: The overall success rates of the URS and ESWL were 97.6 and 82.5%, respectively. Success rates of URS were 98.4 and 95.2% when the stones were smaller and larger than 10mm, respectively. In the ESWL group, the success rates after the third session were 86.3 and 65.4% with stones smaller and larger than 10mm, respectively. The complication rates associated with URS and ESWL were 6 and 4.2%, respectively. The average cost of URS was lower than that of ESWL. CONCLISIONS: In our study, URS with Holmium: YAG laser was more efficacious than ESWL. Considering both the success rate and cost effectiveness, URS should remain the recommended first-line treatment for upper and mid ureter stones.

We investigated the effects of isoflurane-induced hypotension on global cerebral blood flow (CBF), cerebral metabolic rate for oxygen (CMRO,), and the balance between cerebral oxygen supply and demand in 8 mongrel dogs. After endotracheal intubation, anesthesia was maintained with nitrous oxide (50%)-oxygen (50%)-fentanyl (2u/kg/hour). Ventilation was controlled to normocapnia. Mean arterial pressure (MAP) was lowered to 60 mmHg with inhalation of isoflurane. CBF was measured directly using sagittal sinus outflow method before (prehypotension), during (hypotension), and after (posthypotension) isoflurane-induced hypotension. Concomitantly, arterio-sagittal sinus venous oxygen content differen- ce was measured to calculate CMRO2. During hypotension, CBF and CMRO, were measured at 20 minutes after MAP was lowered to 60 mmHg and maintained stably. The time to induce hypotension was 8.6+/-6.1 (mean+/-SD) min. Mean inspired isoflurane concentra tion to induce desired hypotension was 3.1+/-0.9 vol%. The time to recover from hypotension was 28.6+/-7.7 min. MAP and heart rate were reduced significantly during hypotension (p<0.05, respectively) and returned to prehypotensive values during posthypotension. CBF was not changed between three peroiods. CMRO2 was reduced significantly during hypotension (6.5+/-1.2 vs 4.3+/-0.8ml/100/g/min, mean+/-SD, p<0.05) and returned to prehypotensive values during posthypotension. The percentage of CMRO2 reduction from prehypotension to hypotension (% CMRO2 reduction) was 32.5+/-12.9%. CBF/CMRO2 ratio was increased significantly during hypotension (12.8+/-3.3 vs 18.2+/-6.1, mean+/-SD, p<0.05) and lowered to prehypotensive values during posthypotension. Isoflurane-induced hypotension maintained CBF and reduced CMRO2 and therefore favorably influenced the balance between the global cerebral oxygen supply and demand. In conclusion, isoflurane induced-hypotension may be a safe and effective technique in view of the balance of the global cerebral oxygen supply and demand.

We recently experienced an unexpected episode of bilateral vocal cord paralysis following endotracheal extubation after uvulopalatopharyngoplasty and tonsillectomy in 64-year-old man. The patient had no any other clinical manifestations regarding larynx or vocal cord except sleep apnea syndrome prior to this operation. The surgical procedure lasted almost 120 minutes and surgery and anesthesia was uneventful. After restoration of his spontaneous respiration, we tried extubation as usual method. Regardless his effort of spontaneous respiration for several times, he was suddenly apneic and showed declining of arterial oxygen saturation on the pulse oximeter (SpO2). Then we tried reintubation as a decision of laryngeal spasm. This alternative episode of extubation and reintubation was tried again and the causative factor of this respiratory impairment was confirmed as bilateral vocal cord paralysis by fiberoptic bronchoscopic examination in the operating room. Almost two thirds of vocal cord function was restored after six months of operation.

The mutation of p53 tumor suppressor gene is the most common genetic variation of primary malignant tumors. The occurrence, progression and reaction for medical management of cancers can be different according to the characteristics of p53 gene, even if they are same kinds of malignant tumors. In this study, the property of p53 gene in 4 kinds of squamous cell carcinoma cell lines were investigated by using immunocytochemistry, PCR-SSCP, sequencing and Western blot methods. As a result, p53 mutation detected in 3 kinds of squamous cell carcinoma cell lines. Namely, it is found that T in codon 176 changed to A, and G in codon 281 changed to A in KUMA3 cell lines; CC in codon 241 changed to TT in KUMA4 cell lines; G in codon 266 changed to T in KUMA6 cell lines. In single nucleotide polymorphism of codon 72 of p53 gene, the genetic variations are Arg/Pro heterozygote in KUMA3 and KUMA4 cell lines; Arg/Arg homozygote in KUMA5 cell lines; Pro/Pro homozygote in KUMA6 cell lines. These results will provide useful data for p53 gene researches of various squamous cell carcinomas.

Purpose:
The use of an ostomy for urination and defecation leads to reduced quality of life. Although many ostomy management strategies are needed, such strategies are often implemented by patients. Thus, there is a need for a home health care service platform that can be used in ostomy patient management.
Methods:
We developed an ostomy patient management platform by identifying the needs of patients and medical staff through the Chronic Care Ostomy Self-Management Training Program in the United States and from studies conducted in Korea.
Results:
The platform encompassed physical management, psychological management, maintenance of social function, spiritual stability, and home medical care. These components were implemented through monitoring, self-care guidance, and a community platform. For the monitoring function, patients entered their health status in a mobile application (app); the medical staff at the affiliated hospital then monitored the stoma status through a web interface.
Conclusion
Our platform allows medical staff to monitor ostomy patients through a web interface and help such patients to fully manage their ostomy at home using an app. We expect that the continued development of patient-oriented functions in our app will allow ostomy patients to experience quality-of-life improvements.

PURPOSE: To assess the diagnostic efficacy of magnetic resonance (MR) imaging in the detection of a vertebralartery injury occurring from major cervical spine trauma. MATERIALS AND METHODS: Conventional MR findings of 63patients and 63 control subjects were compared to detect a possible change in the vertebral arteries resulted fromtrauma. Plain films, CT and clinical records were also reviewed to correlate the degree of cervical spine injurywith vascular change. RESULTS: Nine cases of absent flow signals in vessel lumen were observed in eight patientsand one was observed in the control group. Patients more frequently demonstrated other abnormalities such asintraluminal linear signals (n=3) or focal luminal narrowing (n=9) but there was no statistical significance. There was a close relationship between degree of cord damage and occlusion of the vertebral artery. CONCLUSION: Conventional MR imaging is useful in the detection of vertebral artery occlusion resulting from cervical spinetrauma.

BACKGROUND: Ketamine has an indirect sympathetic stimulation effect. We investigated heart rate variability (HRV) as a marker of cardiac autonomic function after a target controlled infusion (TCI) of ketamine with a plasma concentration of 30 or 60 ng/ml. METHODS: In 20 adult volunteers, the mean of the R wave to the adjacent R wave interval (RRI), the range of RRI, the root mean square successive difference of intervals (RMSSD), the total power, the low frequency (LF, 0.04-0.15 Hz) power, the high frequency (HF, 0.15-0.4 Hz) power, the normal unit HF (nuHF), the normal unit LF (nuLF), the LF/HF ratio and the SD1 and the SD2 in the Poincare plot were measured before and after a TCI of ketamine. We observed for any psychedelic symptoms or sedation. RESULTS: There were no differences in the mean and range of the RRI, RMSSD, total power, LF power, HF power, nuHF, nuLF, LF/HF ratio, SD1 and SD2 between before and after ketamine administration. The OAA/S score was higher and there were more psychedelic symptoms with a 60 ng/ml plasma concentration than with a 30 ng/ml plasma concentration. CONCLUSIONS: This study did not show any effect of a low plasma concentration of ketamine on the autonomic nervous system.

The sparsity of publication concerning CT findings of tuberculous arthritis prompted authors to retrospectively evaluate 12 patients with tuberculous arthritis for characteristic CT findings. In each patient, the diagnosis of tuberculous arthritis was confirmed by surgery or biopsy. The CT examinations were evaluated by two radiologists retrospectively. Involved joints were the hip joint in seven patients, the sacroiliac joint in three parients, and the shoulder and ankle joint in one patients each. CT features included subchondral bony erosion(12 patients), soft tissue mass in the joint space(nine), widenining of the joint space(eight), ipsilateral muscle atrophy(eight), thickening of the joint capsule(seven), intra-articular effusion(six), soft tissue abscess(five),and bony sclerosis(four). In seven patients with the duration of symptoms less than 1 year, thickening of joint capsule and intra-articular effusion were the predominent findings, while bony sclerosis, gross bone destruction, and soft tissue mass in joint space were seen in five patients with the duration of symptoms longer than 1 year. Our results indicate that CT is useful in the diagnosis of tuberculous arthritis by demonstrating characteristic pathologic changes of the joint space, soft tissue abnormality and bony involvement.
