PURPOSE: To compare the levels of calcium and phosphorus in the aqueous humor and serum of diabetics and non-diabetics. METHODS: We divided patients into two groups: seventy-six non-diabetic cataract patients and fifty-two diabetic cataract patients. The diabetic group was divided again into three subgroups: twenty-six patients with no diabetic retinopathy, thirteen patients with non-proliferative diabetic retinopathy, and thirteen patients with proliferative diabetic retinopathy. The authors compared the levels of calcium and phosphorus in the serum and aqueous humor of cataract patients. Statistic analysis was performed to form two comparisons: 1) a comparison between non-diabetics and diabetics and 2) a comparison among non-diabetics and the three subgroups of diabetics. RESULTS: In serum, calcium levels did not statistically differ between non-diabetics and diabetics. The phosphorus level was also not significantly different. In the aqueous humor, however, while calcium levels did not differ significantly, the phosphorus levels in diabetics were considerably higher than those in non-diabetics. When non-diabetics were compared to the three diabetic subgroups, calcium levels did not differ in serum or aqueous humor, but the phosphorus levels in diabetics with proliferative diabetic retinopathy were significantly higher than those in non-diabetics, diabetics without diabetic retinopathy, and diabetics with non-proliferative diabetic retinopathy. CONCLUSIONS: The level of phosphorus in the aqueous humor and serum of diabetics was significantly increased, especially in diabetics with proliferative diabetic retinopathy. This result may be related to hydrophilic acrylic IOL opacification. Future studies regarding the pathogenic role of a high concentration of aqueous humor and serum phosphorus are required.

PURPOSE: To investigate the difference in corneal endothelial cell loss between diabetic and non-diabetic patients who were divided by the degree of phacoemulsification time after phacoemulsification with intraocular lens implantation. METHODS: Forty eyes of 30 patients with diabetes and 47 eyes of 36 patients without diabetes were divided by phacoemulsification time into 3 groups: less than 40 seconds, from 40 to 80 seconds and over 80 seconds. The corneal endothelial cell density was compared before and 1, 4 and 16 weeks after phacoemulsification by one-way ANOVA. Bivariate correlation analysis was used to identify the correlation between phacoemulsification time and the endothelial density before and 1, 4 and 16 weeks after phcoemulsification. RESULTS: The endothelial cell densities in diabetic and non-diabetic patients with different phacoemulsification time were not significantly different when compared before and 1, 4 and 16 weeks after phacoemulsification (P>0.05). Phacoemulsificaiton time and endothelial cell loss at 1, 4 and 16 weeks also showed no significant correlation. CONCLUSIONS: Diabetes and differences in phacoemulsification time had no significant influence on corneal endothelial cell loss. This result suggests uncomplicated phacoemulsificaion is a safe method for cataract extraction in patients with or without diabetes.

BACKGROUND: Baseline prostate volume (PV) is related with the progression of benign prostatic hyperplasia (BPH). Although recent studies have reported the relationship between BPH and metabolic syndrome, the findings are inconsistent. Thus, this study was performed to investigate the association of PV with metabolic factors and prostate-specific antigen (PSA) in individuals with normal PV and clarify the factors associated with benign prostate enlargement (BPE), including PSA. METHODS: We selected 3,915 health examinees aged >40 yr with a PSA level <4 ng/mL who underwent ultrasonography of the prostate as part of a routine health check-up. These individuals were classified into two groups according to PV: normal PV (PV <30 mL) and BPE (PV > or =30 mL). We investigated the association of PV with metabolic factors and PSA using multiple linear regression analysis, and clarified the factors associated with BPE using logistic regression analysis. RESULTS: The factors associated with PV were PSA, age, and waist circumference in individuals with normal PV. The factors associated with BPE were age, body mass index (BMI), and PSA. The logistic regression analysis adjusted for age and confounding factors showed that individuals with a BMI of 23-24.9 kg/m2, 25-29.9 kg/m2, and > or =30 kg/m2 had higher odds ratios of 1.580 (95% confidence interval, 1.171-2.131; P=0.003), 1.767 (1.332-2.344; P<0.001), and 2.024 (1.042-3.933; P=0.038), respectively, for BPE than individual with a BMI <23 kg/m2. CONCLUSIONS: Abdominal obesity was significantly associated with PV in individuals with normal PV, whereas obesity was an associated metabolic factor of BPE. PSA level was positively associated with PV.

The effect of hyperbaric tetracaine spinal anesthesia was studied in 40 patients having genitourinary surgery in the horizontal lithotomy position. Patients were randomly assigned to one of two groups, after spinal injection, patients in one group were placed immediately in the supine and horizontal lithotomy position, and patients in the second group were placed immediatley in the supine and horizontal position for 10 minutes and then placed into the horizontal 1thotomy position. There were no statistically significant differences in anesthesia sensory level and heart rate of patients placed immediately in the horizontal lithotomy position compared to the patients kept in the supine position for the first 10 minutes after receiving the spinal anesthetic. The ranges of systolic blood pressure were all within normal limits, although systolic blood pressure showed a difference at 5,10 and 60 minute intervals after anesthesia. We conclude that immediate application of the horizontal lithotomy position can be safely practiced in the anesthesia of genitourinary surgery.

Tubular apocrine adenoma and papillary eccrine adenoma are rare sweat gland neoplasms that appear as a small solitary lesion on the scalp or extremities, respectively. Although these lesions are thought to be distinct entities, there are enough similarities between them to group them under the term tubulopapillary hidradenoma or papillary tubular adenoma. We describe a case showing many tubular structures with papillary projection, syringocystadenoma-like structures, and eccrine hirocystoma-like structures in the axillary area. The term of papillary tubular adenoma or tubulopapillary hidradenoma may be prefered in this case.

PURPOSE: The aim of this study was to compare three types of hernioplasty using a mesh: Lichtenstein, Mesh-plug and Prolene Hernia System. METHODS: From February 2002 to April 2007, we retrospectively studied the clinical outcome of 138 cases of adult inguinal hernia patients who had operations performed with the use of mesh. Three types of mesh operations were composed of Lichtenstein repair group (LR group; N=18), Mesh plug repair group (MR group; N=38) and Prolene hernia system group (PHS group; N=82). The Clinical features and outcomes of the three groups were compared by age, sex, operation time, lengths of hospital stay, numbers of post-operative intravenous analgesics, complications, and recurrence. RESULTS: Mean age of three groups was 50.2+/-20.7, 51.0+/-18.4 and 61.5+/-15.9 years for LR. MR, PHS groups, respectively. The PHS group was significantly older than other two groups (P=0.002). The sex, operation time and lengths of hospital stay were not significantly different among the three groups. Numbers of intravenous analgesics used after the operations were 1.7+/-1.2, 2.7+/-2.2, 3.3+/-2.0 in the LR, MR, PHS groups, respectively. A lesser amount of IV analgesics was injected into the LR group than the PHS group. Although some complications occurred such as wound infection, hematoma, dehiscence, testicular edema in the three groups, there were no significant differences among the three groups. There were no recurrences in all three groups. CONCLUSION: We could not find any better outcome among the LR, MR and PHS groups.

PURPOSE: An attempt was made to investigate N-nitrosomorpholine (NNM) induced carcinogenic processes in rat liver. MATERIALS AND METHODS: Rats were fed with NNM (200 mg/l) for 7 weeks, after then stopped. Length of telomere and activity of telomerase were analyzed. Hepatocytes were isolated and grown on tissue culture. Heat shock was treated at 43oC, and patterns of cell death ere evaluted by fluorescent study. Nuclei and nucleoli were isolated for analysis of various signal molecules. RESULTS: Shortening of telomere length presented in NNM treated liver, but induction of telomerase was not found. Ex vivo hepatocytes from 10~12th week showed increased heat shock resistance at 43oC. NNM-treated hepatocytes exhibited heat shock induced cell death (necrosis) after 7 hours, whereas the control showed necrosis after 3 hours. The signal molecules related to nucleolar growth revealed increased expression which included B23, C23, p38, Erk1/2 and p120. Partial degradation of B23 and Erk2 was noted in necrosis of NNM treated hepatocytes induced by heat shock. CONCLUSION: The hepatocytes at the stage of 10~12th week in the stop experiment of NNM are situated in the tumour promotion. Those cells showed various metabolic alterations. We found that the increased growth related signals were accompanied with increased heat shock resistance, telomere shortening but no induction of telomerase.

Bilateral mandibular hypoplasia is found in Treacher Collins syndrome, Pierre Robin sequence, and bilateral craniofacial microsomia. It causes many aesthetic and functional problems such as facial deformities with malocclusion and airway problems. We have corrected bilateral hypoplastic mandible with distraction osteogenesis, which is a highlighted method in mandibular lengthening. For last 3 years 8 months, We applied this method to four bilateral cases, where were Treacher Collins syndrome patients and bilateral craniofacial microsomia patient in rapid multidirectional fashion. A complete ostectomy was made at angle of the mandible and the mandible was fixed 5 days after lengthening was started serially 1mm every 12 hours. After consolidation period for one to three month, the device was removed. We have distracted the mandibles in vertical plane, left.18.8mm, right. 13.4mm, in horizontal plane, left 13.9mm, right 13.7mm on the average. We could achieve good aesthetic results, and their airway problems were improved without any complications.
