1.A Clinical Observation on Ultrasonography of Renal Diseases.
Korean Journal of Urology 1983;24(1):9-14
Recent improvements in gray scale ultrasonic imaging and the development of real time ultrasound made it useful in directing the diagnostic examination and in determining which patients should undergo further, more invasive diagnostic procedures. Ultrasound scanning is cheaper and quicker than computed tomography and angiography, is not invasive and causes little discomfort to the patient. No intravenous contrast medium is used so that reactions to iodine and the difficulty in obtaining venous puncture, frequently a problem in children, are circumvented. There is no ionizing radiation or problem with breath holding. So we made a brief review of the clinical experience and value of ultrasound of renal diseases.

BACKGROUND: Cough reflex in response to extubation of the endotracheal tube is common; however, the effect of remifentanil on cough reflex is uncertain. Therefore, we evaluated the effect of lidocaine and remifentanil on cough reflex following extubation. METHODS: Forty adult patients scheduled to undergo elective surgery in two hours were enrolled in this study. All patients received a standard anesthetic protocol. Following surgery, the patients were randomly divided into two groups, Group L (n = 20), which received 1.5 mg/kg of 2% lidocaine intravenously, and Group R (n = 20), which received 0.5 microgram/kg remifentanil intravenously. Treatment was administered immediately after the patients opened their eyes, after which extubation was performed. We then evaluated breath holding and recorded the number of coughs at 5 minutes, 15 minutes and 30 minutes after extubation. In addition, we checked for sore throat 30 minutes after extubation. RESULTS: The number of coughs was significantly lower in Group R than in Group L at 5 minutes after extubation. However, there was no significant difference in the number of coughs in Group R and Group L at any other times evaluated. CONCLUSIONS: There are no significant differences in suppression of the cough reflex in response to treatment with lidocaine and remifentanil.

Hiccups are due to involuntary contraction of the diaphragm and intercostals muscles. Most hiccups are self-limiting, but sometimes intractable hiccups can lead to multiple problems including exhaustion. Persistent or intractable hiccups may be related to the presence of serious underlying system disease. A 52-year-old male who had suffered from gastric cancer was consulted from surgical department due to persistent hiccups. Initially, he was unsuccessfully managed using conservative method, i.e., breath holding, induced gag reflex, and the oral administration of chlorpromazine. We administered risperidone quicklet, and then the hiccups disappeared. We conclude that risperidone quicklet is one of the useful treatment methods for persistent hiccups.

BACKGROUND: Medications for asthma can be administered either by inhaled or systemic routes. The major advantages of delivering drugs directly into the lungs via inhalation are that higher concentrations can be delivered more effectively to the airways and that systemic side effects are avoided or minimized. Inhaled medications, or aerosols, are available in a variety of devices that differ in required technique and quantity of drugs delivered to the lung. OBJECTIVE: The purpose of this study was to determine the effects of patient education on correct use of metered dose inhaler in patients with asthma. METHODS: Twenty patients with asthma were instructed three times on proper inhaler usage by a physician at two-week intervals. Practical performance and theoretical knowledge were assessed (ten-item assessment). Scoring was done by one physician using a score of 1-3 for each item. RESULTS: The practical performance and theoretical knowledge scores were higher in patients after being instructed three times compared with those who were instructed once (26.2+/-2.2 vs 18.1+/-3.6, p< 0.01). The scores were higher in patients with higher education level com- pared with those with lower education level after three lessons (27.3+/-1.94 vs 24.3+/-1.80, p< 0.05). The most common errors included inadequate actuation time and breath holding, and insufficient activations. CONCLUSION: These findings suggest that patients with asthma be instructed in inhaler use and that their technique be checked regularly and repeatedly depending on education level.

PURPOSE: To evaluate the CT findings of tumor in the pyriform sinus, and to assess by functional study of thelarynx the extent the extent to which its characteristic findings differ from those of supraglottic tumor. MATERIALS AND METHODS: CT scans of 14 patients with tumor in the pyriform sinus were reviewed and compared withthose of 17 patients with supraglottic tumor. In all cases, spiral CT scanning linvolved both quiet breathing andmodified breath holding; we evaluated the images and analysed the primary site of tumors and the displacement ofair in the pyriform sinus. Extra and intralaryngeal extension of the tumors was also assessed. RESULTS: In tumorsin the pyriform sinus, CT findings were thickening of more than two walls in 14, the displacement of air in 9,extralaryngeal extension in 13, extension to the post-cricoid space in 11, invasion of the pre-epiglottic space in13, and widening of the cricothyroid space in 8 patients. In supraglottic tumors, CT findings were thickening ofthe medial wall in 17, extralaryngeal extension in 1, extension to the post-cricoid space in 1, invasion of theipsilateral paralaryngeal space in 17, and of the contralateral paralaryngeal space in 6, invasion of thepre-epiglottic space in 11, and widening of the cricothyroid space in 9 patienhts. In this type of tumor thedisplacement of air was not seen. CONCLUSION: The characteristic CT findings of tumor in the pyriform sinus werethickening of more than two walls of the pyriform sinus and the anterior or medial displacement of air. To assessthe site at which a tumor originates, spiral CT scanning is needed, together with functional study.

OBJECTIVE:
To explore the change of the amplitude of P wave, T wave and ST segment of 12 lead electrocardiogram (ECG) in children with breath holding spell.
METHODS:
A total of 29 children (24 males and 5 females) with breath holding spell in Second Xiangya Hospital, Central South University were enrolled for this study from October, 2009 to September, 2015. Their ages ranged from 3 months to 6 years, with an average of 1.82±1.27 years old. The control group consisted of 30 age-matched and gender-matched healthy children. All subjects were underwent electrocardiography by the SR-1000A comprehensive automatic electrocardiograph analyzer, and the changes of the ECG parameters were compared between the two groups.
RESULTS:
Compared with the control group, the amplitude of P-wave of V5 lead was decreased [(44.10±23.98) vs (58.30±21.19) μV, P<0.05], the amplitude of T-wave of V6 lead was increased [(423.80±122.6) vs (350.00±105.73) μV, P<0.05], the amplitude of ST segment of II lead was increased [(84.80±39.97) vs (57.30±38.77) μV, P<0.05], the amplitude of ST segment of aVR lead was increased [(-77.60±37.41) vs (-51.00±33.46) μV, P<0.05], the amplitude of ST segment of aVL lead was increased [(35.20±28.24) vs (17.70±33.90) μV, P<0.05], the amplitude of ST segment of V5 lead was increased [(111.00±59.36) vs (69.00±36.33) μV, P<0.05], the amplitude of ST segment of V6 lead was increased [(79.30±45.51) vs (51.30±33.19) μV, P<0.05].

BACKGROUND: Sevoflurane has been used to provide an inhaled induction by using a vital capacity breath, which is fast and has few side effects. We compared the clinical effects of a vital capacity inhalation induction (VCII) with sevoflurane in patients of preoxygenation or air-breathing before anesthetic induction. METHODS: After IRB approval, patients were randomly assigned to receive preoxygenation (O2 group, 70 patients) or air breathing (Air group, 70 patients) via SIBI (Single Breath Induction) connectorTM before VCII with 8% sevoflurane in 75% N2O/O2 from primed circuit. The clinical characteristics were compared between two groups in respect to prolongation of breath holding after loss of consciousness (response to verbal command) and side effects (airway, hemodynamic, motor) during VCII. RESULTS: O2 group showed lower incidence (60.0% vs. 87.1%, P < 0.05) and shorter duration (27.1 s vs. 36.4 s, P < 0.05) in prolongation of breath holding than Air group. Otherwise, there were no significant differences in clinical effects between two groups. CONCLUSIONS: We found that preoxygenation reduces the incidence and duration of prolongation of breath holding during VCII with sevoflurane compared with air-ventilation before VCII. We suggest that the prolongation of breath holding might be related to Hering-Breuer response to maximal lung inflation during VCII.

Korean Journal of Preventive Medicine 2003;36(3):248-254
OBJECTIVE: This study was conducted in order to investigate predictors of smoking cessation in outpatients. METHOD: Subjects were 401 adult smoking patients who saw their doctors in the outpatient setting at a university hospital, regardless of their willingness of otherwise in smoking cessation. Physicians delivered a brief, stop smoking prompt to all patients who smoked one or more cigarettes a day. Then they referred to on-site counselors who provided a brief, nurse assisted intervention with a survey to a randomly assigned intervention group (200 smoking patients), whom the counselors telephoned later to prevent relapse or promote the motivation to quit, or gave only a survey to a control group (201 smoking patients). After at least 5 months, self-reported current smoking cessation was confirmed later using cut-off values of 7 ppm or less in expired alveolar air after breath holding portable CO analyzer. RESULTS: After 5 months, subjects in the intervention group were 1.56 times (95% C.I. 0.89-2.73) more likely to quit smoking than those in the non-intervention group (14.0% vs. 9.0%). Willingness to quit smoking in a month, scheduled admission in a month, self efficacy score and FTND (Fagerstrom Test for Nicotine Dependence) score were all significantly related with smoking cessation. In stepwise multiple logistic regression, previous attempts to quit smoking were significant instead of self efficacy score. In the intervention group who had willingness to quit smoking in a month (132 smoking patients), FTND score, whether quit date was today, and whether quit promise paper was submitting were all significantly related with smoking cessation. In stepwise multiple logistic regression, scheduled admission in a month and whether quit date was today were significant predictor variables. Smoking cessation treatment should be tailored to individual smoking patients considering these predictors.

The clinical utility of transcranial doppler ultrasonography (TCD) in cerebrovascular disease has been extended recently. Although number of studies have been performed to define normal reference values of TCD measurements, they have some limitations to be used as reference values which include relatively small number of subjects, lack of data about some cerebral vessels and/or parameters. This study was aimed to obtain clinically useful reference values of TCD measurements with consideration of the influence of age and sex in Korean adults, particularly who are in stroke-prone age group. We measured flow velocities, pulsatility indecies, side-to-side differences and vasomotor reactivities of all intra-and extracranial cerebral arteries using TCD in 209 normal Korean adults (age, 23-78 years; 94 men and 115 women), and analyzed the influence of age and sex on those measurements. With advancing age, subjects showed significant reduction in velocity measurements and increase in pulsatility indecies of most examined arteries. Females showed hight velocities of middle cerebral, internal carotid, vertebral and basilar artery and lower pulsatility indecies of middle cerebral arteries compared with males. Asymmetry measurements including side-to-side differences and asymmetry index, and ,breath holding index testing vasomotor reactivity were also measured and the normal range of those parameters were calculated. Since present study included large number of subjects, and checked paramenters of TCD in both extra- as well as intracranial cerebral arteries, we are convinced that these results can be used as a reference data of TCD measurements in Korean adults.

AIMTo explore whether hypoxic response and breath holding at sea level could predict acute mountain sickness (AMS).
METHODS113 men aged (19 +/- 1) years took part in this study. Blood oxygen saturation (SaO2), heart rate and blood pressure were measured during the course of breathing 10% O2 for 10 minutes and breath holding. Two days later after reaching Lasa (3 658 m altitude) by air, the symptomatic scores of AMS were evaluated. Then the relations between them were analyzed.
RESULTSThe SaO2 reduced progressively and the heart rate speeded up, while the blood pressure represented increase at first and then decrease within 10 min during the short-term hypoxia. The heart rate was lower during short-term hypoxia in subjects who developed AMS than in subjects doing well. But significant reverse correlation existed only between AMS scores and heart rate at 7th min after hypoxic breathing (r = -0.176).
CONCLUSIONLimited information can be gained on AMS score by assessing physiological responses to short-term hypoxia and breath holding at sea level.
