PURPOSE: The pharmacologic effect of atropine on HPS can be considered to control pyloric muscle spasm. Therefore, we studied the effects of intravenous atropine sulfate on the clinical course of HPS, and periodically observed the ultrasonographic appearance of the pyloric muscles after atropine treatment. METHODS:From April 1998 to May 1999, 14 infants who were diagnosed with HPS were treated with intravenous atropine sulfate. Intravenous atropine sulfate was administered at an initial dose of 0.04mg/kg/day, which was divided into 8 equal doses. The daily dose was increased by 0.01 mg/kg/day until vomiting was controlled for an entire day while infants received unrestricted oral feeding. Ultrasonographic examinations were performed during hospitalization and repeated at least every 2 months until normalization of pyloric muscles was confirmed. RESULTS: Intravenous atropine was effective in 12 of 14 infants with HPS and the conditions of 9 of them improved. Two infants who were not free from vomiting despite a week of intravenous atropine sulfate treatment underwent pyloromyotomy. A series of ultrasonographic examinations were done after vomiting had improved with intravenous atropine sulfate. The ultrasonographic findings showed good passage of gastric contents through pyloric canals despite thickening of the pyloric muscles. CONCLUSION: Intravenous administration of atropine sulfate is an effective therapy for HPS and can be an alternative to pyloromyotomy. (J Korean Pediatr Soc 2000;43:763-768)

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.

Chronic osteomyelitis continue to be a therapeutic challenge. The osteomyelitis also implies chronic ischemia of the diseased bone ; thus systemic antibiotic treatment may not be as effective as we want. In 1972, Klemm developed a new procedure to supplement saucerization in the treatment of chronic osteomyelitis, alternative to irrigation and suction-drainage, i.e., Gentamicin-PMMA Beads. The authors analysed 35cases of the chronic osteomyelitis which were admitted and treated by sauceriztion and Gentamicin-PMMA Beads in Department of Orthopaedic Surgery, Korea Veterans Hospital from Aug. 1984 to Jan. 1988.

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.

BACKGROUND: Retrograde interlaminar ventral epidural injection (RIVEI) may hypothetically be more effective if the catheter is placed at the ventrocaudal aspect of the exiting nerve. We tested that hypothesis by measuring ventral and dorsal epidural contrast flow during RIVEI. METHODS: To perform RIVEI, a 17 G Tuohy needle was inserted to access the epidural space. A 19 G epidural catheter was inserted and advanced through the needle, passing in a caudal direction to the lower aspect of the contralateral pedicle. Fluoroscopic images were recorded at 1.5 ml increments of contrast. Based on the images of contrast dispersal, the extent of contrast spreading was assessed in 82 patients. RESULTS: All 82 patients (100%) injected with 3.0 ml contrast medium demonstrated ventral epidural spreading. Mean spreading level from the catheter tip was 2.21 +/- 0.93 with 3.0 ml of contrast. Spreading to the superior aspect of the supra-adjacent intervertebral disc was observed in 67/82 (81.7%) of RIVEIs with 3.0 ml of contrast injected into the ventral epidural space. We found that 3.0 ml of contrast reached the inferior aspect of the infra-adjacent intervertebral disc in 95.1% (78/82) of RIVEIs performed. CONCLUSIONS: Our findings imply that a one-level RIVEI may be sufficient in situations where a two-level injection would currently be used.

Ehlers-Danlos syndrome (EDS) is a very rare genetic disorder characterized by defects in the production of connective tissue. Among them, vascular EDS is the subtype known to have the worst prognosis due to fragile blood vessels. Accordingly, we would like to report a case report of a patient with vascular EDS with a review of the literature on possible massive transfusion and anesthesiological problems. Patients with vascular EDS have very weak blood vessels and tissues that are easily broken. So there is a high possibility of unexpected massive bleeding during emergency surgery in these patients. Therefore, the anesthesiologist should be fully prepared for the possibility of massive blood loss, keeping in mind the possibility of damage to large blood vessels. The central vein must be secured using ultrasound, sufficient blood and fluids must be prepared, and equipment capable of rapid administration must be perfectly prepared before the start of operation.

BACKGROUND: The greater occipital nerve (GON) block has been frequently used for different types of headache, but performed with rough estimates of anatomic landmarks. Our study presents the values of the anatomic parameters and estimates the effectiveness of the ultrasound-guided GON blockade. METHODS: The GON was detected using ultrasound technique and distance from external occipital protuberance (EOP) to GON, from GON to occipital artery and depth from skin to GON was measured in volunteers. Patients with occipital headache were divided into two groups (ultrasound-guided block: group S, conventional blind block: group B) and GON block was performed. The same parameters were measured on group S and VAS scores were assessed at pretreatment, 1 week and 4 weeks after treatment on both groups. RESULTS: The GON had distance of 23.1 +/- 3.4 mm (right) and 20.5 +/- 2.8 mm (left) from EOP to GON. Its depth below the skin was 6.8 +/- 1.5 mm (right) and 7.0 +/- 1.3 mm (left). The distance from GON to occipital artery was 1.5 +/- 0.6 mm (right) and 1.2 +/- 0.6 mm (left) in volunteers. Initial VAS score of group S and group B patients were 6.4 +/- 0.2 and 6.5 +/- 0.2. VAS score of 4 weeks after injection were 2.3 +/- 0.2 on group S and 3.8 +/- 0.3 on group B (P = 0.0003). CONCLUSIONS: The parameters measured in this study should be useful for GON block and ultrasound-guided blockade is likely to be a more effective technique than blind blockade in occipital headache treatment.

BACKGROUND: The purpose of the current study is to investigate anatomical relationships between the muscle overlying the distal transverse carpal ligament (TCL) and the thenar motor branch of the median nerve. METHODS: Of the 192 wrists that underwent open carpal tunnel release, a muscle belly overlying the TCL was observed on the distal margin of TCL in 25 wrists and ligament exposure could not be achieved without transection of it. We recorded surgical findings of these 25 wrists. The origin of the recurrent motor branch arising from the major median nerve was marked on the axial and coronal section diagrams of the wrist. RESULTS: The presence of muscle overlying the TCL was seen in 25 wrists (21 patients, 13%). The locations of origin were distributed not only on the radial side but anterior or ulnar side of the major median nerve. Abnormal branches originated from the unusual side in 14 cases (56% of those with a muscle overlying the TCL): central-anterior side in eight cases, ulnar-anterior side in five cases, and ulnar side in one case. These anomalous branches were frequently associated with the muscle belly overlying the TCL in our study regardless of the origin site. The branches were prone to cut if careless midline incision along the third web space was performed. Unusual origin and aberrant pathway of the recurrent thenar motor branch were associated with the presence of a muscle overlying the TCL. CONCLUSIONS: A thorough knowledge of the standard and variant anatomy of the muscle belly and recurrent motor branch in the carpal tunnel is fundamental to prevention of complications such as muscle wasting or atrophy by iatrogenic motor branch injury during carpal tunnel release.

Statement of problem: A conventional 3-unit fixed partial denture design with a pontic between two retainers is the most commonly used. However, in cases where the mental nerve is in close proximity to the second premolar, a cantilever design can be considered. As such, logical and scientific evidence is lacking for the number and position of implants to be placed for partially edentulous patients, and no clear-cut set of treatment principles currently exist. Purpose: The purpose of this study was to evaluate prognosis of implant-supported fixed partial dentures, and to compare changes in bone level which may rise due to the different factors. Material and method: The present study examined radiographical marginal bone loss in patients treated with implant-supported fixed partial dentures(87 prostheses supported by 227 implants) and evaluated the influence of the span of the pontic, type of the opposing dentition. Clinical complications were studied using a retrospective method. Within the limitation of this study, the following result were drawn. Result: 1. Seven of a total of 227 implants restored with fixed prostheses failed, resulting in a 96.9% success rate. 2. Complications encountered during recall appointments included dissolution of temporary luting agent (17 cases), porcelain fracture (8 cases), loosened screws (5 cases), gingival recession (4 cases), and gingival enlargement (1 case). 3. Marginal bone loss, 1 year after prosthesis placement, was significant(P<0.05) in the group that underwent bone grafting, however no difference in annual resorption rate was observed afterwards. 4. Marginal bone loss, 1 year post-placement, was greater in cantilever-type prostheses than in centric pontic protheses(P<0.05). 5. Marginal bone loss was more pronounced in posterior regions compared to anterior regions(P<0.05). 6. The degree of marginal bone loss was proportional to the length of the pontic(P<0.05). Conclusion: The success rate of implant-supported fixed partial dentures, including marginal bone loss, was satisfactory in the present study. Factors influencing marginal bone loss included whether bone graft was performed, location of the pontic(s), location of the surgical area in the arch, pontic span. Long-term evaluation is necessary for implant-supported fixed partial dentures, as are further studies on the relationship between functional load and the number of implants to be placed.
