Purpose: To compare efficacies of bupivacaine-lidocaine and ropivacaine-lidocaine mixtures in terms of inducing retrobulbar anesthesia during vitrectomy. Methods: Sixty patients who underwent retrobulbar anesthesia during vitrectomy were divided into two groups. Patients in group 1 received a mixture of bupivacaine and lidocaine (n = 30); patients in group 2 received a mixture of ropivacaine and lidocaine (n = 30). The effects of the two combinations were retrospectively compared and analyzed. The onset times of analgesia and akinesia were measured. Two hours after surgery, sensory blockade was assessed by touching the corneas with cotton swabs and by communicating with patients. Ocular movement was evaluated in four gaze direction quadrants. A 10-point visual analog pain scale was used to assess pain during and 2 hours after surgery. Intra- and postoperative complications were recorded. Results: The mean analgesia onset times in groups 1 and 2 were 94.62 ± 28.87 and 92.32 ± 35.53 seconds, respectively (p = 0.071); the mean akinesia onset times were 147.89 ± 59.35 and 132.57 ± 76.38 seconds (p = 0.223), respectively. Patients in group 2 reported significantly less postoperative pain and exhibited less postoperative ocular movement, compared with patients in group 1 (both p = 0.002). One patient in group 1 experienced respiratory depression after retrobulbar blockade. Conclusions When retrobulbar anesthesia is required during vitrectomy, a ropivacaine-lidocaine mixture and a bupivacaine-lidocaine mixture induce anesthesia with similar rapidity. However, the ropivacaine-lidocaine mixture is safer and affords better-quality intra- and postoperative anesthesia.

OBJECTIVE: The purpose of this study was to determine the frequency and distribution of cytogenetically abnormal miscarriages in couples with spontaneous abortions (SA) or recurrent miscarriages (RM). METHODS: Karyotyping of specimens from 164 abortuses with SA and 86 abortuses with RM was successfully performed according to the standard cytogenetic methods using G-banding technique. RESULTS: Among the total 164 cases of SA group, 81 (49.4%) were euploid and the rest (83, 50.6%) showed chromosomal abnormalities. In RM(> or =2) and RM(> or =3) group, 31 (36.0%)/27 (34.6%) cases were euploid and 55 (64.0%)/51(65.4%) cases were abnormal, respectively. A statistically significant difference was found in the rate of cytogenetic abnormality between SA and RM groups (P<0.05). In all groups, women with advanced maternal age (> or =35 years) had a higher rate of chromosome anomalies compared with women younger than age 35 (normal:abnormal = 32.4%:67.6% for > or =35 years and 53.8%:46.2% for <35 years in SA; 19.2%:80.8%/21.7%:78.3% for > or =35 years and 43.3%:56.7%/40.0%:60.0% for <35 years in RM(> or =2) and RM(> or =3), respectively; P<0.05). In SA group, an increase of normal karyotypes was noted with increased gestational age (<10 week, 38.0%; 10-15 week, 53.5%; 16-20 week, 65.7%). In RM group, most of cases were in <10 week and the frequency of trisomies with chromosomes 1 to 10 were increased compared with that of SA. CONCLUSION: There was a statistically significant difference in the frequency and distribution of chromosomal abnormalities between SA and RM groups. Our results will provide useful information for diagnosis and genetic counseling of patients with SA or RM.

Intravascular catheter embolism is common and the most important complication of subclavian catheterization. The catheter fragment can lead to pulmonary embolism, vascular perforation, sepsis, arrhythmia, and even death. The intravascular foreign body can be removed using surgical or non-surgical methods. With technological advances, the percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. A commonly used method for retrieving intravascular foreign bodies is the loop snare. Sometimes biopsy forceps can be used. We experienced a case of non-surgical retrieval of an intravascular foreign body. We used the standard loop snare technique to remove a 5-cm catheter fragment from the left pulmonary artery.

PURPOSE: Verrucous carcinoma is a rare, low-grade and well-differentiated squamous cell carcinoma, representing as a warty tumor. Estimation of the incidence for cutaneous lesions is not available because they are rare. We describe a case of verrucous carcinoma, a rare type, complication of a chronic pressure ulcer of duration more than 15 years. METHODS: A 17-year-old boy presented with a large lesion involving the sacral area, which had been neglected for about 15 years. He had a history of surgical extirpation 2 years ago, but not cured. Examination revealed a cauliflower-like mass arising from an irregularly oval-shaped tumor which was 6.0x4.5cm in size with signs of infection and ulcer. The lesion involved the sacrococcygeal area, spreading to both medial gluteal regions. The perianal skin did not appear to be directly affected. RESULTS: A preoperative punch biopsy revealed a extremely well differentiated verrucous carcinoma. There were positive results in immunohistochemistry in the items of p53, p63, Ki-67. An 'en-bloc' excision of the tumor with the clinically normal surrounding tissue was carried out. Reconstruction was achieved by local regional flap. Histopathological findings of the excised area fully confirmed the preoperative biopsy report. It remained free of recurrence for a period of about 8 months. CONCLUSION: We believe that in patients with buttock involvement, regardless of the extent of such tumors, surgical therapy should be considered as the first-choice of treatment as reconstruction can be performed without excessive impairment for the patient.

PURPOSE: The clinical syndrome of unilateral finger ischemia, caused by digital artery occlusions from embolization from the palmar ulnar artery associated with repetitive striking of the palm, has been called the hypothenar hammer syndrome(HHS). We report the case of a man with this unique disease probably caused by manual work. METHODS: A 52-year-old male left-hand dominant manual worker complained of pain and coldness in the left 4,5th finger. On physical examination, there was a tip necrosis and the result of Allen's test was mildly positive(sluggish filling of hand from the ulnar artery). Arteriograms confirmed occlusion of the distal ulnar artery without direct perfusion of the superficial palmar arch and distal digital artery. Surgical bypass with reverse autologous vein grafting was performed between ulnar artery and superficial palmar arch, common digital artery. RESULTS: He had an uneventful postoperative course and has remained asymptomatic for 18 months since discharge. Patency has been confirmed by color doppler with resolution of cold intolerance and successful digital preservation. CONCLUSION: We introduce a very unique pattern of vascular ischemic disease and recommend the arterial bypass with vein interpositional grafting.

BACKGROUND: Plastic tubes have recently been used for blood collection tubes in clinical laboratories. The silicone coated plastic tube is said to be very similar with the glass tube and to show no difference with the glass tube in routine blood test except for some tests such as hormone tests and drug monitoring. So, we investigated the influence of plastic tube on the thyroid hormone test using two types of plastic vacuum tubes. METHODS: A total of 105 cases for the total triiodothyronine (T3), total thyroxine (T4), and thyroid stimulating hormone (TSH) were studied. The glass tube was a plain glass tube, and the plastic tube was a serum separator tube with gel. The plastic vacuum tubes used in this study were the SST II plus tube (Becton Dickinson, Franklin Lakes, USA) and the Vacuette tube (Greiner Bio-One, Kremsmunster, Austria). An IMMULITE 2000 analyzer (Diagnostic Products Corporation, Los Angeles, USA) was used to measure the total T3, total T4 and TSH. RESULTS: Comparisons of the measured values within 1 hour of blood collection in the plastic tube with that in the glass tube are as follows. There was no difference between the Vacuette tube and the glass tube for the three tests, while there was statistically significant difference between the SST II plus tube and the glass tube for the total T3 and total T4. CONCLUSIONS: It might need more cautious interpretation of the results by a solid-phase, competitive chemiluminescent enzyme immunoassay, when the plastic vacuum tube is used as a blood collection tube instead of the glass tube.

PURPOSE: We evaluated the usefulness of Re-188 sulfur colloid for radiation synovectomy and therapy of intraperitoneal metastasis. MATERIALS AND METHODS: We investigated the labeling efficiency of Re-188 sulfur colloid on various conditions. The stability of Re-188 sulfur colloid was observed at room temperature for 24 h and in human serum and synovial fluid for 72 h. The particle size distribution of Re-188 sulfur colloid was rneasured by filtering with various pore size filters. Animal experiment was performed in mice and rabbits. RESULTS: The labeling efficiency of Re-188 sulfur colloid was 64,5+/-5.8% (n=5) at the conditions of sodium thiosulfate 40 mg, EDTA Na2.2H2O 0,8 mg, KReO4 0.8 mg at pH l. After purification, the radiochemical purity was higher than 99%. The stability of Re-188 sulfur colloid was high (>99%) at room temperature for 24 h and in human serum and synovial fluid for 72 h. The particle size distribution of Re-188 sulfur colloid was 0.3% (<1 micrometer), 11.2% (1~5 micrometer), 35.8% (5~10 micrometer) and 52.8% (>10 micrometer). In mice, 1 h postinjection of Re-188 sulfur colloid into tail vein, uptakes in lung, liver and muscle were 37.30+/-5.36, 32.33+/-5.79, 6.60+/-0.02% 1D/organ respectively. After I.p. injection in rnice, the uptakes of extraperitonial organs of Re-188 sulfur colloid at 1 and 24 h were 0.1+/-0.1, 0.4+/-0.1% ID/organ, and the excretions through urine and feces (~70 h) were low (2.68+/-0.80, 0.95+/-0.17%). When Re-188 sulfur colloid was injected to synovial space of rabbit, the uptake in other organs except knee was very low. CONCLUSION: Re-188 sulfur colloid showed high labeling efficiency, stability and potency for clinical use.
