Pulmonary Aspergillosis*

Infantile hypertrophic pyloric stenosis (IHPS) is the most common condition requiring abdominal surgery in early infancy, and is caused by hypertrophied pyloric muscle. The development of successful surgical treatment in the early 1900s by Fredet and Ramstedt made it possible for infants worldwide to survive. Modern pediatric anesthetic techniques have virtually eliminated mortality from surgical management. Atropine sulfate is a cholinergic blocking agent with potent antimuscarinic activity that decreases peristaltic contractions by relaxing smooth muscles. We treated two cases of IHPS with incomplete pyloromyotomy in 3-month-old and 5-month-old male infants by administering atropine sulfate intravenously. They were free from vomiting after 5 days of intravenous atropine sulfate treatment. In these rare cases of persistent vomiting or refractory emesis following incomplete pyloromyotomy, there may be a role for atropine sulfate.

Among the late postoperative complications of the acute dissection of aorta, the fistula between dilated distal aorta and pulmonary parenchym is so rare that only few case have been reported sporadically. Although the aortopulmonary fistula is one of a fatal condition that needs prompt surgical intervention, with an appropriate management it is well controllable condition. Early diagnosis and urgent surgical intervention is the only way to prevent catastrophic hemorrhage. We experienced a surgical management of aortoplumonary fistula which occurred between upper lobe of the left lung and distal aortic dilatation of previous aortic bypass graft which was performed for Debakey type I acute aortic dissection.

BACKGROUND: Surgical correction of the full spectrum of esophageal atresia with tracheoesophageal fistula has improved over the years, but the mortality and morbidity assoiated with repair of these anomalies still remains high. MATERIAL AND METHOD: We retrospectively analyzes 27 surgically treated patients with esophageal atresia and tracheoesophageal fistula at Dong-A University Hospital between January 1992 and March 1997. RESULT: There were 21 male and 6 female patients. Mean birth weight was 2.62+/-.385 kg(2.0~3.4 kg). Twenty- four(88.9%) had esophageal atresia with distal tracheoesophageal fistula, and 3(11.1%) had pure esophageal atresia. Four(14.8%) infants were allocated to Waterston risk group A, 18(66.7%) to group B, and 5(18.5%) to group C. In eighteen(66.7%) infants with associated anomalies, cardiovascular anomalies were the most common. Three had a gap length of 3.5 cm or greater(ultra-long gap) between esophageal segments, 7 had 2.0 to 3.5 cm(long gap), 8 had 1.0 to 2.0 cm(medium gap), and 9 had 1 cm or less(short gap) gap length. Among 27 neonates, 3 cases underwent staged operation, late colon interposition was done in 2, and all other 24 cases underwent primary esophageal anastomosis. Oerative mortality was 2/27(7.4%). Causes of death included acute renal failure(n=1), empyema from anastomotic leak(n=1), necrotizing enterocolitis(n=1), sepsis(n=1), insulin-dependent diabetus mellitus(n=1 . There were 4 anastomosis- related complications including stricture in 3, leakage in 1. Mortality was related to the gap length(p<.05). CONCLUSION: Although the complication rate associated with surgical repair of these anomalies is high, this does not always implicate the operative mortality. The overall survival can be improved by effective treatment for combined anomalies and intensive postoperatve care.

BACKGROUND: Decreased heart rate variability(HRV) has been shown to be an independent predictor of poor outcome after acute myocardial infarction, Spectral analysis of HRV has recently been shown to be a reliable noninvasive test for quantiative assessment of cardiovascular autonomic regulatory response. We estimated the reproducibility and circadian rhythm of HRV parameters in patients with acute myocardial infarction. METHODS: Three consecutive 24-hour ambulatory electrocardiographic recordings were made in 24 patients with acute myocardial infarction, with 10~14 days after the acute attack, and analyzed for HRV parameters of both frequency and time domains. Parameters of frequency domain include low frequency(LF) and high frequency(HF) components. Parameters of time domain include sdRR, SDANN, SD, pNN50, rMSSD, HRV index. RESULTS: Mean total, low frequency and high frequency amplitude spectral densities were 33msec, 19msec and 11msec, respectively. Mean values of sdRR, SDANN, SD, rMSSD, pNN50 and HRV index were 103msec, 90msec, 47msec, 28msec, 7% and 32, respectively. Coefficients of variation(CV) of total amplitude spectral density, and low and high frequency components were 7%, 9% and 12%, respectively. CV of most HRV parameters of time domain were also around 10% except rMSSD and pNN50. Heart rate increased in the morning to be sustained during the day time and decreased in the night. Heart rate variability of high frequency component decreased in the early morning to be sustained during day time with increase in the night. CONCLUSIONS: We conclude that in the predischarge period of acute myocardial infarction, HRV parameters of frequency and time domains are reproducible and there are some morning fall of cardiac vagal activity.

Induction of A-V block by tachycardia is a well-known phenomenon. But there are few case reports of bradycardia-dependent A-V block. We report a case of bradycardia-dependent A-V block with review of literatures. This patient was a 52-year-old female who complained of dizziness and anterior chest discomfort. Electrocardiographic recording demonstrated complete A-V block. Monitor electrocardiographic recordings during sitting position and after atropine administration demonstrated decrease of degree of block from complete A-V block to first degree A-V block. The occurrence of complete A-V block from bradycardia during supine position suggests a phase 4-dependent block. After a permanent ventricular pacemaker was implanted, the patient recovered and was without symptoms during 12 months follow up.

Reliable and valid evaluation of hand strength is of paramount importance in determining the effectiveness of various normative data area needed to interpret evaluation data, to set realistic treatment goals and to assess a patient's ability to return to employment. The primary purpose of this study was to establish normal value of grip and pinch strength for men women in normal Korean adult. A Jamar dynamometer(Hydraulic Hand Dynamometer. PC 5030, USA) was used to measure grip strength and Jamar pinch gauge(Hydraulic Pinch Gauge, PC 5030HPG, USA)was used to measure tip, key and palmar pinch. Two hundreds forty eight male and two hundreds thiry one female adults, aged 20 to 74 years were tested for using standardized positioning with their shoulder adducted and neutrally rotated, elbow flexed at 90。 and the forearm and wrist in neutral position. Right and left hand data were stratified into age groups for both sexes. This stratification provides a means of comparing the scores of individuals to that of normal subjects of the same aged and sex. The following results were obtained; 1. The average grip strength of the dominant hand was highest(43.9±7.3kg)in 3rd decade male group. 2. The average tip pinch strength of the dominant hand was highest in 4th decade(7.3±3.5kg)and 5th decade (7.3±2.4kg) male group. 3. The average key pinch strength of the dominant hand was highest in 5th decade(8.3±2.3 kg)male group. 4. The average palmar pinch strength of the dominant hand was highest in 4th decade(9.6±3.3 kg)male group. 5. A high correlation was seen between grip strength and age, but a low correlation between pinch strength and age. 6. The average grip strength of dominant hand was 5.6% higher than that of nondominant hand in men, and 6.5% higher in women. 7. In pinch strength, palmer pinch strength was highest among the three groups of pinch strength, then key pinch and tip pinch strength in order. 8. The mean scores of the dominant hand were larger than that of the nondominant hand on all hand strength.

Successful repair of lacerated tendons must restore continuity of the tendon and should yield a strong tenorrhaphy. Mechanical strength of repair should be adequate to early postoperative motion and mobility, The optimal repair technique must be able to withstand the rigors of early motion and also must not interfere with tendon healing. The relative strength of three suture methods of lacerated tendon were measured by mechanical disruption in effort to determine the strength of suture technique. Fifty-four Calcaneal tendons of 27 the New Zealand white rabbit were transected at mid portion and repaired with the three suture technique: group 1, Kessler suture, group 2, Pennington’s modified-Kessler suture and group 3, augmented- Becker suture technique. Each group was composed of 18 calcaneal tendons. Nine rabbits were sacrified immediately after suture, nine in postoperative 2 weeks and nine in postoperative 4 weeks Six calcaneal tendons in each three experimental group were obtained immediately after suture, at postoperative 2 and 4 weeks respectively. Tensile strength, maximum strength and modulus of elasticity of all experimental specimens were measured with Instron-UTM-4-100(Toyo-Baldiwin, Japan). The results were evaluated statistically to compare the strength of the three suture technique at three different periods. The tensile strength was predominantly strongest in augmented-Becker method among three suture technique at immediate suture, postoperative 2 weeks and 4 weeks respectively. The augmented Becker repair was strongest in maximum stress among Kessler and modified Kessler repair at immediate operation, postoperative 2 weeks and 4 weeks respectively. The augmented Becker repair was highest in modulus of elasticity than Kessler method and modified-Kessler method at immediate operation, postoperative 2 weeks and postoperative 4 weeks respectively. Tensile strength, maximum stress and modulus of elasticity were gradually increased from immediate operation to postoperative 4 weeks, but there were not statistically significance between experimental three suture methods at postoperative 4 weeks.
