PURPOSE: This study was to evaluate the clinical usefulness of 99mTc-MDP bone scintigraphy for assessing vascular ingrowth into the ocular implants after enucleation or evisceration. MATERIALS AND METHODS: Twenty-four patients (M:F=7:17, mean age: 36 years), who buried a coralline hydroxyapatite after uncomplicated enucleation or evisceration surgery were studied. Dynamic and static scintigraphy on the orbit fossa were obtained after injection of 740 MBq 99mTc-MDP to evaluate the status of vascularization. The study was performed from the 3 to 33 weeks after surgery. According to the visual analysis, activity greater than nasal bridge was graded as 4, equal to the nasal bridge as 3, less than nasal bridge but greater than normal orbit as 2, greater than normal orbit but less than grade 2 as 1. Uptake ratio was also calculated by measuring the implants activity (H) and contralateral orbit activity (N). Grading score and uptake ratio were compared with clinical outcome of vascularization. Additionally, we also analyzed the vascularization status as time lapse between primary surgery and scintigraphic study and surgical methods. RESULTS: Twenty-one patients who had bone scintigraphy at 11 weeks after surgery showed increased uptake above grade 2 and greater H/N ratio than 1.56. Of these, 19 patients who had drilling surgery for permanent peg application showed adequate bleeding during the procedure. The activity grade and uptake ratio were inversely correlated with vascular ingrowth. Higher than grade 2 or greater than 1.56 in H/N ratio seemed to be an indicator for better prognosis. Accomplishment of vascularization was not affected by the surgical way such as enucleation or evisceration. CONCLUSION: 99mTc-MDP bone scintigraphy can be a useful method to evaluate the vascularized status of implants. Adequate time for 99mTc-MDP bone scintigraphy may be 11-20 weeks after enucleation or evisceration.

There is still discussion concerning the methods for treating Tossy type 3 dislocations of the acromioclavicular joint. Since 1995, the authors have treated 10 patients of type 3 dislocations by arthroscope-assisted modified Weaver and Dunn operation with favorable results. The operation consisted of diagnostic shoulder arthroscopy, arthroscopic resection of acromial end of coracoacromial ligament with bone block, excision of distal end of clavicle, bone block transfer of coracoacromial ligament into the medullary canal of clavicle, and augmentation between coracoid process and resected distal end of clavicle with the Mersilene tape. The advantages of this arthroscope-assisted modified Weaver and Dunn operation are as follows: (1) Using the shoulder arthroscope, associated patholgy in the shoulder joint can be found and treated appropriately. (2) Arthroscopic resection of the acromial end of coracoacromial ligament can give the small incision and least damage to the deltoid muscle so that immediate post-operative range of motion exercise can be possible. (3) Bone block transfer of coracoacromial ligament and augmentation between coracoid process and resected clavicular end can prevent displacement of the resected clavicular end.

In this study, the trypsin gene (bgtryp-1) from the German cockroach, Blattella germanica, was cloned via the immunoscreening of patients with allergies to cockroaches. Nucleotide sequence analysis predicted an 863 bp open reading frame which encodes for 257 amino acids. The deduced amino acid sequence exhibited 42-57% homology with the serine protease from dust mites, and consisted of a conserved catalytic domain (GDSGGPLV). bgtryp-1 was determined by both Northern and Southern analysis to be a 0.9 kb, single-copy gene. SDS-PAGE and Western blotting analyses of the recombinant protein (Bgtryp-1) over-expressed in Escherichia coli revealed that the molecular mass of the expressed protein was 35 kDa, and the expressed protein was capable of reacting with the sera of cockroach allergy patients. We also discussed the possibility that trypsin excreted by the digestive system of the German cockroach not only functions as an allergen, but also may perform a vital role in the activation of PAR-2.

Rotor syndrome is a rare disease of hereditary hyperbilirubinemia transmitted with autosomal recessive trait. In general, Rotor syndrome shows direct hyperbilirubinemia and there has been several reports since Sons's report in 1966, in Korea. A 34-year-old female was admitted with the chief complaint of intermittent icteric sclera for 24 years. There was no family history of jaundice. Rotor syndrome was diagnosed by oral cholecystogram, BSP retention test, 99mTc-DISIDA scan, liver biopsy and electron microscopy study of liver biopsy specimen. We report this case with brief review of the literature.

A l3-year-old boy was admitted to our hospital with severe hypertension, visual blurring, excessive sweating, polyuria and polydipsia. On admission, the blood pressure was persistently elevated at 230/180 mmHg. and an ophthalmologist was consulted, the funduscopic examination showed bilateral grade IV retinopathy. Cardiomegaly with dyspneic on exertion and persistent tachycardia were present. In urine examinations, proteinuria was sustained and glycosuria was traced. B. U. N. was 9.4 mg/dl. Urinary catecholamine was 12480 mic.g./day ; urinary V. M. A. was 20.2 mg./day. Regitine test was positive but histamine test was not performed. Presacral air insufflation with nephrotomography showed egg sized soft tissue mass locating at just above the upper pole of left kidney. He was operated with transabdominal approach. There were bilateral pheochromocytomas on suprarenal areas. Two weeks after operation, he was discharged with good general condition and we report this case with review of literatures.

Although many factors associated with difficult intubation have been known, predictors of difficult mask ventilation are not well known. We experienced a case of nearly complete airway obstruction following usual anesthetic induction which needed various emergency treatments. The patient had a preoperative diagnosis of contact granuloma of right posterior vocal cord and bilateral vocal cord palsy but later was found out as invasive laryngeal cancer. Upon the surgical field of view, both vocal cords were showing significantly thickened and fixated appearance and was considered as in the critical narrowing state with the potential of complete obstruction. Using C-MAC® video laryngoscope we were able to see the narrowed vocal cord and choose proper size of endo-tracheal tube. Consequently, intubation was successfully done and operation was conducted. From this case, we have lessons that physicians should examine the patient's airway more carefully in case of laryngeal mass and prepare emergency measures.

A 6-month-old boy was scheduled for a laryngeal mass excision and tracheal bougienage for secondary subglottic stenosis. Following successful excision of the laryngeal mass, a tracheal tube was temporarily extubated for tracheal bougination. However, tracheal re-intubation using a direct laryngoscope with the Miller blade failed because of mucosal swelling and bloody secretions. Following multiple intubation attempts, the patient's peripheral oxygen saturation had decreased to 52%. Immediately, a video laryngoscope was requested, and, by using the C-MAC® video laryngoscope, the patient was successfully re-intubated. Because pediatric patients are more vulnerable to desaturation, extreme caution should be used in securing airways even during a short apneic period. Using a video laryngoscope at the first intubation attempt would be useful for successful tracheal intubation.
