Adequate radiographic demonstration of renal injury following blunt abdominal trauma is an important guide totherapy. The diagnostic evaluation of renal injuries usually begins with excretory urography, but not providedetailed information about the extent of injury. The need for a more accurate noninvasive modality led us toinvestigate the use of CT. We evaluated with CT and excretory urography 30 selected patients suspected of havingmajor renal injury. Of these patients 11 were also underwent arteriography for assessment of renal arterialinjuries. In this paper, we wish to analyze the result of the above modalites, particulary angiography and CT. Thebrief results were as follow. 1. Among 30 patients, 21 cases were male and 9 cases were female. About one third ofthese occured between the age of 20-29. 2. All cases were nonpenetrating blunt traumas. 3. Renal injuries werecategorized into 3 groups. Category I is minor renal injuries(14 cases), II is major renal injuries(1 cases), andIII is catastrophic renal injuries(3 cases). 4. IVP is the most common inital diagnostic modality and good forscreening of patients, but lack of specificity. In our study the specificity is about 33%. 5. CT is more accuratein detecting hematoma, parenchymal laceration, fracture and extravasation of urine, but agiography is moreconfirmative in diagnosis of vascular injuries. 6. Conservative management was done in 19 cases; 13 cases ofcategory I and 6 cases of II. Operation was performed in 11 cases: 1 case of category, I, 7 cases of II and 3cases of III. 7. Associated injuries were noted in 17 cases(57%).

BACKGROUND: There have been recent reports on the effects of the addition of intrathecal midazolam to bupivacaine on spinal anesthesia. Therefore, the effects of the addition of intrathecal midazolam to bupivacaine on spinal anesthesia and peri-operative sedation were investigated. METHODS: Thirty one ASA class 1 and 2 patients, scheduled for transurethral resection of the bladder or prostate (TURB or TURP), were randomly divided into two groups. Group B (n = 15) received bupivacaine 12 mg, and normal saline 0.6 ml, whereas group BM (n = 16) received bupivacaine 12 mg, midazolam 2 mg, and normal saline 0.2 ml. The blood pressure (BP), heart rate (HR), arterial oxygen saturation (SaO2), bispectral index (BIS) and Observer's Assessment of Alertness/Sedation Scale (OAA/S scale) scores were recorded every 5 minutes, both before and during the spinal anesthesia. The sensory blockade was measured using a pin-prick test, and motor blockade evaluated using the Bromage motor scale. In addition, the side effects, including pruritus, nausea, vomiting, and headache, and so on, were observed for a period of 24 hours. RESULTS: There were no differences in the motor and sensory block and recovery between the two groups. However, a difference was found in the time to first recognition of pain and the BIS scores between the two groups. CONCLUSIONS: Intrathecal midazolam did not, itself, affect the spinal anesthesia, but was found to have a statistically prolonged postoperative analgesic and more sedative effects.

Postherpetic neuralgia (PHN) is a sequela of acute herpes zoster infection and is defined as pain persisting more than 1 month. The patients with PHN suffer from a persistent neuropathic pain. There are many treatments for PHN but some people occasionally do not respond to the conventional therapies. Neurodestruction using neurolytic agents are beneficial to patients with severe intractable pain because of it's prolonged pain-relief and simplicity, inexpensiveness. We report a case that we managed successfully a patient with intractable thoracic PHN using intrathecal alcohol neurolysis.

In maxillofacial surgery endotracheal tube provides patent airway and prevents patient from aspirating the blood. But serious complications such as tube obstruction or injury have been reported. In this case, endotracheal tube injury by surgical saw during Lefort I osteotomy occurred. We could not exchange the defective tube for a good one using laryngoscope or fiberoptic bronchoscope due to edema and blood in nostril and oral cavity. We didn't have any tube exchanger available too. Therefore, to provide patent and safe airway, we packed gauze around the lacerated part of tube, provided positive end expiratory pressure ventilation and increased oxygen flow. After anesthesia, the damaged tube was safely removed and there were no respiratory complications.

Hiccup is caused by synchronous contractions of the diaphragmatic and intercostal muscles followed by the closure of the glottis. Intractable hiccup is defined as hiccup bouts lasting more than 48 hours or recurring despite various treatments. Recently we have experienced a case of postoperative intractable hiccup. We failed to stop intractable hiccup by pharmacological treatment, but succeeded by unilateral phrenic nerve block.

BACKGROUND: Pulmonary venous flow velocity pattern (PVFVP) is widely used to assess LV diastolic function. It is known that the parameters of PVFVP have a significant correlation with the ratio of peak early diastolic filling velocity (E) to peak filling velocity at atrial contraciton (A) measured in the transmitral flow. However, the correlations between parameters of superior vena caval flow (SVCF) and transtricuspid E/A ratio have not been reported. Therefore the present investigation was performed to elucidate these correlations. METHODS: Fifty patients (26 men, mean age 63.1+/-11.1 years), who did not have significant tricuspid valvular disease and restrictive filling pattern on tricuspid and superior vena caval doppler, were included in this study. SVCF was recorded with the transducer positioned at subxiphoid area and the sample volume placed 2 cm within the superior vena cava. Blood flow across the tricuspid valve was obtained from standard four chamber view or modified parasternal four chamber view with the sample volume placed on leaflet tips. Recording was made during midexpiratory apnea. The following doppler parameters were measured: transtricuspid E and A velocity, E/A ratio: systolic (S) and diastolic (D) peak velocities and time velocity integrals (TVI), S/D velocity ratio, S/D TVI ratio, atrial reversal peak velocity (ArV) and TVI (ArTVI) in SVCF. RESULTS: 1) In SVCF, S velocity (63.7+/-11.8 cm/s vs 73.4+/-13.6 cm/sec, p<0.05), S TVI (17.4+/-3.6 cm vs 21.1+/-6.2 cm, p<0.05), ArV (30.0+/-6.9 cm/s vs 37.2+/-7.3 cm/s, p<0.005), and ArTVI (2.7+/-0.8 cm vs 3.3+/-0.8 cm, p<0.01) were significantly decreased in group E/A>1. And D TVI (7.1+/-3.0 cm vs 5.2+/-3.1 cm, p<0.05) and D/S TVI ratio (0.41+/-0.13 vs 0.26+/-0.14, p<0.05) were significantly increased in group E/A>1. 2) As E/A ratio increased, diastolic TVI (r=0.315, p<0.05) and D/S TVI ratio (r=0.448, p<0.001) increased, and ArTVI (r=-0.376, p<0.01) and ArV (r=-0.416, p<0.01) decreased. 3) As E peak velocity increased, SVCF D peak velocity increased (r=0.305, p<0.05). CONCLUSIONS: Tricusupid E/A ratio has positive correlations with D TVI and D/S TVI ratio, and negative correlations with ArTVI and ArV. But there were no correlations in S velocity, D velocity, and S/D velocity ratio as the relation of mitral E/A ratio with PVFVP.

Background/Aims: Adequate bowel preparation is important for successful colonoscopy. We aimed to evaluate the clinical feasibility and effectiveness of abdominal vibration stimulation in bowel preparation before therapeutic colonoscopy. Methods: A single center, prospective, randomized, investigator-blinded study was performed between January 2016 and December 2016. Patients for therapeutic colonoscopy were prospectively enrolled and assigned to either the vibrator group or walking group. Patients who refused to participate in this study as part of the experimental group consented to register in the control group instead. During the preparation period, patients assigned to the walking group walked ≥3,000 steps, whereas those assigned to the vibrator group received abdominal vibrator stimulation and restricted walking. All patients received the same colon cleansing regimen: 4-L split-dose polyethylene glycol (PEG) solution. Results: Three hundred patients who received PEG solution for therapeutic colonoscopy were finally enrolled in this study (n=100 per group). Bowel cleansing with abdominal vibration stimulation showed almost similar results to that with walking exercise (Boston Bowel Preparation Scale score for the entire colon: vibrator vs walking vs control, 7.38±1.55 vs 7.39±1.55 vs 6.17±1.15, p<0.001). There were no significant differences between the vibrator group and walking group regarding instances of diarrhea after taking PEG, time to first diarrhea after taking PEG, total procedure time, and patient satisfaction. Conclusions This study indicates that, compared with conventional walking exercise, abdominal vibration stimulation achieved similar rates of bowel cleansing adequacy and colonoscopy success without compromising safety or patient satisfaction.

BACKGROUND: Pulmonary venous diastolic flow follows the pattern of mitral flow and is dependent on the pressure difference between the pulmonary vein and the left atrium (LA). The magnitude of the decrease in LA pressure in early diastole depends on both the volume of the blood leaving the LA and the stiffness of the left ventricle (LV) and the LA. Relaxation process is known to govern early diastolic compliance. We hypothesized that in patients with decreased early diastolic compliance due to LV relaxation abnormality, there may be rapid rise in LV and LA pressure, resulting in early peak of pulmonary venous D wave as early LV diastolic filling progress. This study was undertaken to define this hypothesis and to examine the relation of the time interval between E wave peak and D wave peak to mitral doppler indexes. METHOD: Patients with significant mitral or aortic valvular disease, or patients with LV ejection fraction below 60%, or patients who have pseudonormal or restrictive LV filling pattern on mitral and pulmonary venous Doppler, were excluded from this study. Mitral Doppler indexes including peak E velocity, peak A velocity, E wave acceleration time (EAT) and deceleration time (EDT) were measured. E/A ratio was calculated. The isovolumic relaxation time from aortic valve closure (Ac) to the onset of E wave , the time interval from Ac to the peak of E wave (AcE), the time interval from Ac to the peak of D wave, and the diastolic time from Ac to R of electrocardiogram (AcR) were measured by the pulsed wave Doppler and phonocardiography. The time interval from the peak of E wave to the peak of D wave (ED) was calculated by the subtraction of AcE from AcD. RESULTS: 1) ED is significantly shorter in patients with E/A<1 than those with E/A> or =1 (58.9+/-27.4 msec versus 74.7+/-17.2 msec, p<0.05). 2) ED correlated with IVRT (r=-0.400, p<0.01), AcR (r=0.414, p<0.01), but not with E/A ratio, EDT, or EAT. 3) Multivariate linear regression analysis with all the previously mentioned variables showed that IVRT, AcR, and EAT were independent determinants of the ED. CONCLUSION: This study demonstrates that the ED is shortened in patients who are regarded as having LV relaxation abnormality and that ED is affected by IVRT, AcR, and EAT.

PURPOSE: Mycoplasma pneumoniae infection is relatively common in childhood. Its extrapulmonary manifestations have been reported so much, but hepatitis associated with it has been reported rarely in Korea. METHODS: A clinical study was performed on 556 patients of M. pneumoniae pneumonia diagnosed serologically at Gil hospital from January 2001 to December 2004. We reviewed 65 cases among these patients, who had elevated level of serum AST and ALT greater than 50 IU/L respectively without evidence of hepatitis A, B, C, Cytomegalovirus and Ebstein-Barr virus infections. RESULTS: Hepatitis occurred in 11.7% of Mycoplasma pneumoniae pneumonia, especially in fall and winter times. Male to female ratio was 1.2: 1 and the mean age was 4 years and 3 months. Besides hepatitis, cough (95.4%), sputum (52.3%) and dyspnea (12.3%) were common as pulmonary manifestations. And among gastrointestinal manifestations, nausea/vomiting (26.2%) was the most common symptom, followed by poor oral intake (12.3%), diarrhea (12.3%) and abdominal pain (6.2%). In addition to hepatomegaly (4.6%) and splenomegaly (4.6%), coarse breathing sound was the most common physical manifestation, followed by rale (63.1%), pharyngeal injection (26.2%), and rash (10.8%). Anemia was noted in 20.0%, neutrophilia in 10.8%, eosinphilia in 38.5% and thrombocytosis in 6.2%, respectively. Mean level of ESR and CRP was 32.02 mm/hr and 6.69 mg/dL, respectively. Mean level of AST and ALT was 293.80 IU/L and 181.48 IU/L, respectively. Hyperbilirubinemia was noted in 7.7% and hypoalbuminemia was noted in 58.5%. Lobar or lobular pneumonia (78.5%) was the most common finding in chest X-ray and left lower lobe (39.2%) was most commonly affected. Pleural effusion was noted in 26.2%. Mean duration of hospitalization was 9.91 days. Serum AST/ALT level was normalized within 9.94 days and pulmonary consolidation resolved within 14.29 days. CONCLUSION: The prognosis of M. pneumoniae hepatitis is good. However, liver function should be considerately checked in M. pneumoniae infection because its incidence is not so low.

OBJECTIVE: We tried to see the prevalence and correlates of symptoms of depression in an adolescent population in Korea, and collected the basal data for mental health promotion of adolescents. METHOD: We sampled 2,203 adolescents among 71,102 adolescents living in Puchon City in Korea by the randomized clustered sampling method. The Center for Epidemiologic Studies Depression scale(CES-D) was used to measure depressive symptoms. The measurements were conducted through visiting schools. Of the 2,203 adolescents(aged 13 to 18) who were sampled, 1,972 persons completed CES-D and sociodemographic questions. The response rate was 89.5%. RESULT: 1) The prevalence rate of 'probable' depressive symptoms with cutoff point 16 was 34.3% in the boys and 47.5% in the girls. 2) The prevalence rate of 'definite' depression symptoms with cutoff point 25 was 17.4% in the boys and 20.6% in the girls. 3) We could not find any meaningful difference in the average of CES-D from the districts where they live, the course of their education, and their religions. 4) We used the logistic regression analysis to find the risk factor for adolescent depression in these samples. Among the variables of sex, age, economic status considered by self, family structure, satisfaction with school degree, it was most important risk factor in adolescent depression to dissatisfy with their school degrees. Compared it with fully satisfied group, the odds ratio was 8.850. The group of mid to low socioeconomic status had the odds ratio 2.007 compared with high socioeconomic status. The girls had the odds ratio 1.307 compared with the boys. 5) The male versus female ratio was 1:1.38 in the total students and 1:1.88 in the middle school students, and 1:1.13 in the high school students. The male versus female ratio was relatively low in the high school students. It was the result of the high prevalence of depressive symptoms in the high school boys, and it was due to the large burden to their school degrees. CONCLUSION: The depressive symptoms checked by CES-D were very common among adolescents in Korean urban area. The prevalence of depressive symptoms was 34.3% in the boys and 47.5% in the girls. The result that male versus female ratio was relatively low in the high school adolescents, and the group that were dissatisfied with the school degrees had high risk of depressive symptoms, revealed that the students had large burden to their school degrees and so they needed special concerns.
