PURPOSE: We evaluated a rapid preparation procedures for the labeling and quality control of 99mTc-ECD, MAG3, and MIBI using microwave heating and Sep-Pak cartridges. MATERIALS AND METHODS: 99mTc labeling of ECD, MAG3, and MIBI kit preparation was performed according to the package inserts with microwave heating modification. Heating time was 10-15 sec, and heating was performed with 3 mm plastic bottle with screw cap to prevent radiation contamination. Labeling efficiency was obtained with C18 or Alumina N Sep-Pak cartridges. RESULTS: The radiochemical purity of 93~96% for 99mTc-ECD and 95~99% for 99mTc-MIBI was obtained using Alumina N Sep-Pak cartridge. The optimum irradiation time of microwave method for 3 ml 99mTc-labeled radiopharmaceutical solution was 10 sec for 99mTc-ECD and 99mTc-MIBI, and 15 sec for 99mTc-MAG3. The RESULTS of quality control data with Sep-Pak cartridges were well correlated with TLC method. The total preparation time of these radiopharmcaeuticals was 5~6 min including quality control procedure. CONCLUSION: This study demonstrates that radiopharmaceuticals preparation by microwave heating and quality control by Sep-Pak cartridges can be efficiently utilized as an alternative to the recommended method by manufacturer's manual.

We report a case of giant cell tumor of the tendon sheath in a 36-year-old male, who presented an asymptomatic, firm, 1.0 × 0.8 × 0.4cm-sized nodule, involving the volar aspect of the distal phalanx of the right index finger about 1 year ago. Histopathologically, the enucleated lesion showed four lobules surrounded by thin connective tissue, each of which demonstrated the variable cellularity and the polymorphic cell population consisting of foam cells, spindle-shaped fibroblasts, histiocyte-like cells and multinucleated giant cells with heavy hemosiderin deposits near the periphery, in the collagenous stroma. He has done well with no recurrence during one year of follow-up since the operation.

To evaluate the detection of HPV DNA according to subtype of lesions of uterine cervix and its clinical applicability, in situ hybridization (ISH) and immunohistochemistry for HPV were performed in 189 cases of uterine cervical lesion, including 23 cases of low grade squamous intraepithelial lesion (SIL), 115 cases of high grade SIL and 51 cases of invasive carcinoma. Positive immunostaining, brown precipitate, was mainly noted in the nucleus of koilocytes in the superficial and intermediate layer. Positivity of immunostaining was 21.7% in low grade SIL, 13.0% in high grade SIL and 9.8% in invasive carcinoma. Positive reaction in ISH, red precipitate, was noted in the nucleus of not only koilocytes but also non-koilocytes in the superficial and intermediate layer, and dot precipitate was rarely identified in the nest of squamous cell carcinoma. Based on HPV subtype, 6/11 was 21.7% in low grade SIL, 16/18 was 32.2% and 39.2% in high grade SIL and invasive carcinoma, respectively. With regard to their associated HPV types, low grade SILs were heterogeneous and high grade SILs and invasive carcinomas were related with the high oncogenic risk group only. The correlation of HPV subtypes with panHPV was 91.3% in low grade SIL, 91.3% in high grade SIL and 98.0% in invasive carcinoma. These results suggest that detection of HPV infection by ISH may be a more useful method than immunohistochemistry and application of the HPV subtype probe with the panHPV probe could improve the sensitivity of ISH.

Objective: : Traumatic intracranial hematomas have been rarely evacuated by endoscopic surgery. The frontal lobe is the usual location for the traumatic intracerebral hematoma (TICH). Endoscopic evacuation for the frontal TICHs via an eyebrow incision is to be presented as minimally invasive surgery. Methods: : Thirteen patients with frontal TICHs were managed with endoscopic hematoma evacuation via eyebrow incision. After making the incision in the lateral eyebrow, a small frontal craniotomy was made, and the hematoma was evacuated under direct visualization of a rigid endoscope. No catheter was placed. Orbital rim resection, hematoma evacuation rate, surgical complications, and outcome at discharge were analyzed. Results: : Men were 11 and the mean age was 54 years old (range, 27–86). Orbitotomy was performed in four patients, and no effect on the hematoma evacuation rate was observed. More than 80% of the hematoma volume was successfully removed in 10 cases. Hematoma configuration was not related to the hematoma evacuation rate. None of the patients underwent revision operation or decompressive craniectomy. Conclusion : Endoscopic evacuation of the TICHs with the supraorbital approach may be a good method to evacuate the hematoma located in the frontal base.

The Varicella zoster virus is responsible for two common infectious diseases: chicken pox(Varicella) and shingles(Herpes zoster). Chicken pox is the primary infection. After the initial infection, the virus remains dormant in sensory ganglia until reactivation may occur decades later. The subsequent reactivation is Herpes zoster. Herpes zoster of the trigeminal nerve distribution manifests as painful, vesicle eruptions of the skin and mucosa innervated by the affected nerve. Oral vesicles usually appear after the skin manifestrations. Reports of osteomyelitis of jaw after trigeminal herpes zoster are extremely rare. We report a case of osteomyelitis on mandible caused by herpes zoster infection which was treated by antiviral drug, curettage. At 1 year post-operatively, mandibular mucosa had healed without recurrent sign. But post-herpetic neuralgia is remained.

Tuberculous bronchoesophageal fistula is a rare disease. We experienced a case of the tuberculous bronchoesophageal fistula, which was found by endoscopy and surgically confirmed. A sixty seven years old female patient complained of foreign body sensation in the throat and frequent aspiration, especially after liquid meal. Esophagoscopic ex- aminatian showed the orifice of the fistula in the midesophagus at the level of 28 cm from the incisors. Esophagogram showed bronchoesophageal fistula between midesophagus and the right intermediate bronchus. A bronchoscopy visualized fistulous tract with granulation in the right intermediate bronchus. Biopsy specimens obtained from the bronchus revealed the esophageal tissue with granulation and multinucleated giant cells. Fistulectomy with wrapping procedure was performed successfully. Surgical pathologic findings confirmed a small focal granuloma and chronic inflammations, compatible with tuberculosis. There was no evidence of malignancy at the specimens. She was treated with anti-tuberculous agents and became well.
