OBJECTIVES: This study was to determine whether drainage after radical hysterectomy and bilateral pelvic lymphadenectomy can reduce the risk of postoperative morbidity as compared with no drainage. METHODS: 165 patients with stage Ia2 to Ilb underwent radical hysterectomy and bilateral pelvic lymphadenectomy between January 1995 and May 1997, and those medical records were analyzed, Closed suction drains were placed in group I (n 102), not in group II (n 67). All surgeries were perforrned by the same surgeon in a uniform method. RESULTS: The characteristics of two groups were similar for mean age, preoperative weight, total protein, serum albumin, tumor cell histology, invasion depth, and tumor stage. There was no difference in mean operation time in two groups. But mean estimated blood loss was more in group I than group lI(p<0.05), Postoperative ileus and postoperative stay was similar in both groups. The incidence of pelvic lymphocyst and febrile morbidity in two groups were comparable with 17% in group I and 27% in poup II, but not statistically significant(p>0.05). Rehospitalization rate was higher in group I than in group II. CONCLUSION: Pelvic drainage didn't reduce the postoperative febrile morbidity and lymphocyst formation. Therefore the author could not find any necessity to perform the drainage following radical hysterectomy and pelvic lymphadenectomy.

Purpose:
To assess the clinical outcomes of scleral buckling (SB) without subretinal fluid drainage (SRFD) on primary rhegmatogenous retinal detachment (RRD).
Methods:
The medical records of patients with RRD treated via SB without SRFD from March 2009 to Feb 2018 were retrospectively reviewed. Cases with histories of previous intraocular surgery (except cataract removal) were excluded. The primary and final surgical success rates were the main outcome measures. Pre- and post-operative visual acuity and intraocular pressure (IOP), factors that might affect the surgical success rate, secondary operative procedures, re-operation rates, and complications were analyzed.
Results:
A total of 66 eyes of 66 patients were included. The mean patient age was 38.9 ± 18.6 years and the mean symptom duration 19.23 ± 25.14 days. The retinae were reattached after single surgeries on 57 eyes (success rate 86.36%); the final success rate was 100% after a second operation (when necessary). Of the nine eyes requiring additional surgery, seven required vitrectomy and two vitrectomy combined with buckle revision. The mean preoperative logMAR visual acuity of 0.578 ± 0.647 improved to 0.518 ± 0.512 at 1 month after surgery (p < 0.001) and to 0.262 ± 0.372 at the last follow-up visit (p < 0.001). The postoperative IOP was higher than the preoperative IOP at 3 months (p = 0.024).
Conclusions
Scleral buckling without SRFD used to treat primary RRD afforded a high reattachment rate (compared to those of previous reports employing vitrectomy or scleral buckling with SRFD). Given the possible complications of SRFD, our method may be a safe and feasible surgical option, affording good results with few complications in patients with primary RRD.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.

PURPOSE: To compare results between in femtosecond laser and microkeratome LASIK correction of myopia METHODS: We retrospectively analyzed the result of 94 eyes of 47 patients in the femtosecond group (F) and 103 eyes of 52 patients in the microkeratome group (M). All patients had undergone LASIK using either a femtosecond laser or a microkeratome for making of flap. Patients were divided into groups I (6D< or =) and II (> or =6D) according to preoperative myopia. Each patient was followed up for over 6 months with measurements of uncorrected visual acuity and manifest refraction at 1 week and 1, 3, and 6 months after operation. Complications during and after the operation were reviewed retrospectively in two groups 6month after the operation. RESULTS: In groups F-I, F-II, M-I, and M-II, postoperative 6-month uncorrected visual acuity was 0.98+/-0.08, 0.96+/-0.09, 0.97+/-0.03, 0.98+/-0.09. At the 6-month follow-up, there were no significant differences between the two groups in uncorrected visual acuity and mean spherical equivalent. Corneal opacity was found in 3 eyes in group M and complication related with flap was found 1 eye in group F and 4 eyes in group M. CONCLUSIONS: During a 6-month follow up, LASIK using either a femtosecond laser or a microkeratome has an similar effect in uncorrected visual acuity and mean spherical equivalent. Thus LASIK for using femtosecond laser can be used as an alternative procedure to correct myopia.

The incidence of the cutaneous tuberculosis has shown a steady decline over the past decades. This parallels the decreasing incidence of pulmonary tuberculosis. We experienced 5 cases of cutaneous tuberculosis from January 1990 to February 1991. We present herein 4 cases of cutaneous tuberculosis. They were 3 cases of vulgaris and 1 case of tuberculosis verrucosa cutis. Mantoux tests were done except one case and were reactive in all cases. Culture for Mycobacterium tuberculosis were done but Mycobacterium tuberculosis were not cultivated in the all cases. Histopathological findings showed tuberculoid granulomas in the dermis except one case and no acid fast bacilli were demonstrated on AFB stains.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.
