Lymphomatoid papulosis is a strange disease; clinically benign, histologically malignant. Clinically, it may simulate pityriasis lichenoides et varioliformis acuta. The diagnosis is based on the typical histopathological features suggestive of malignant lymphoma, due to the presence of polymorphous lymphoid infiltrate consisting of small lymphocytes intermingled with conspicuous large atypical cells. We experienced a case of lymphomastoid papulosis in 35-year-old woman. Initially, her skin lesions developed as erythematous papules on the extremities, gradually spreading centrifugally with a tendency to involute slowly without treatment, leaving brown wrinkled surface and shallow ulceration. These skin lesions tended to become worse in warm weather and better in cold weather. At first visit, multiple erythematous grouped, ulcerated papules and nodules are seen. 18 months after first visit, most skin lesions are regressed except 5 erythematous pinhead sized papules on right leg in spite of no treatrnent. Labcratory examiniations of CBC, VDRL, urinatlysis, blood chemistry and chest X-ray were all within normal limits. Histopathologically there were hygerkeratosis, mild acanthosis, exocytosis in epidermis, and numerous lymphoid cells were infiltrated especially on perivascular and periappendegeal area, and many atypical cells showing hyperchromatic nuclei, kidney-shaped nuclei and mitotic figures in dermis.

PURPOSE: Laparoscopy-assisted distal gastrectomy (LADG) has become a viable alternative treatment for patients suffering with early gastric cancer. Surgeons have long thought that obesity might increase the rate of intraoperative or postoperative complications. This study was performed to evaluate the impact of obesity, according to the learning curve, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. METHODS: We retrospectively reviewed 100 patients who had undergone LADG for gastric cancer between September 2004 and May 2007 at Keimyung University Dongsan Medical Center. We measured the degree of obesity by using the body mass index (BMI: kg/m(2)), and we compared the surgical outcomes between the low BMI group (BMI < 25 kg/m(2), n=72) and the high BMI group (BMI >25 kg/m(2), n=28). We further subdivided the patients into the surgeons' number of cumulative LADG cases, the early learning curve group (from the first patient to the 50th patient) and the late learning curve group (from the 51th patient to the 100th patient). We analyzed them in terms of the operation time, the amount of intraoperative bleeding, the number of retrieved lymph nodes, the rate of operative morbidity and the length of the postoperative hospital stay. RESULTS: There no significant differences between the high and low BMI groups in terms of the patients' clinicopathologic characteristics and surgical outcomes, but there was a statistically significant difference in the operation times between the high BMI (303.3 min) and low BMI groups (269.3 min, P=0.029). The postoperative morbidity was not different between the high BMI (25%) and low BMI groups (12.5%, P=0.12). However, when we subdivided the patients by the learning curve, there was a statistically significant difference for the operation time (360 vs 297 minutes, respectively), postoperative morbidity (41.7 vs 10.5%, respectively) and the postoperative hospital stay (15.5 vs 8.6 day, respectively) between the high BMI and low BMI groups at the early learning curve period. Especially for male patients, the early learning curve period showed significant differences in the operation time, the postoperative morbidity and the postoperative hospital stay between the high BMI and low BMI groups, but in case of the female patients, there was no difference in postoperative morbidity and the length of the postoperative hospital stay. At the late learning curve period, there was no difference according to gender and obesity. CONCLUSION: Obesity itself does not increase operative morbidity when performing LADG in patients with gastric cancer. However, at a surgeon's initial period of performing LADG, a careful approach seems to be required for male obese patients.

Normal retinal vessels around the first and the second bifurcations were analysed with fundus photographs taken by Zeiss fundus camera. Horizontal disc diameter was set to 10, which was taken as standard units. 1. Distances of the first and the second bifurcations of the retinal vessels from the disc margin were variable; average distance being 10.01 +/- 4.83 (2.0~29.0) and 11.36 +/- 7.99 (1.5~40.0) for the first arterial and venous bifurcations, and 19.47 +/- 8.03 (5.0~42.0) and 22.84 +/- 10.49 (5.0~47.0) for the second arterial and venous bifurcations. 2. Arterial and venous diameters were: 0.56 +/- 0.11 (0.4~1.0) and 0.72 +/- 0.16 (0.5~1.1) at one to two disc diameters from the disc margins, and 0.53 +/- 0.09 (0.4~0.6) and 0.62 +/- 0.14 (0.4~0.9) at three to four disc diameters. 3. Ratio of venous to arterial diameters were 1.285 +/- 0.332 (0.57~2.00) at the first bifurcations and 1.137 +/- 0.266 (0.77~1.77) at the second bifurcations. The ratio was smaller at periphery than at central area. 4. Diameters of arteries became narrower more gradually than those of veins after bifurcations. After the second bifurcations, ratio of the sum of branched vascular diameters to the vascular diameters before bifurcations were 1.617 (0.9~3.0) for artery and 1.454 (0.9~2.8) for vein.

BACKGROUND: Obese type 2 diabetic subjects are recently increasing in Korea, indicating the importance of insulin resistance rather than insulin secretory defects in the pathophysioloy of type 2 diabetes. The purpose of this study is to evaluate the safety and efficacy of fixed dose rosiglitazone/metformin combination therapy in poorly controlled subjects with type 2 diabetes mellitus. METHODS: 12 type 2 diabetic subjects who had a HbA1c > 11% or fasting plasma glucose > 15 mmol/L were included. After a 2 week screening period, the subjected took the fixed does rosiglitazone/metformin for 24 weeks. The treatment with rosiglitazone/metformin began at week 0 with an initial dose of 4 mg/1000 mg and, unless tolerability issues arose, subjects would be increased to 6 mg/1500 mg at week 4 and at week 8 to the maximum dose of 8 mg/2000 mg. The primary object of this study was to characterize the magnitude of HbA1c reduction from baseline after 24 weeks of rosiglitazone and metformin treatment in poorly controlled type 2 diabetics. RESULTS: The mean age of the subjects was 48.9 +/- 10.6 years old, body mass index was 25.0 +/- 3.5 kg/m2, HbA1c was 12.0 +/- 1.0%, and fasting plasma glucose was 16.3 +/- 3.1 mmol/L. HbA1c was reduced to 7.54 +/- 1.45% and fasting plasma glucose reduced to 7.96 +/- 2.38 mmol/L at week 24. The proportion of HbA1c responder who showed the reduction from baseline of > or = 0.7% or HbA1c < 7% was 11 among 12 subjects (91.7%). 41% of the subjects (5 among 12 subjects) achieved HbA1c level < 7.0% and 75% (9 among 12 subjects) achieved HbA1c level < 8.0%. CONCLUSIONS: In this study, rosiglitazone and metformin combination therapy was effective in glycemic control in poorly controlled subjects with type 2 diabetes mellitus.

BACKGROUND: Germline mutations in the breast cancer-associated genes BRCA1 and BRCA2 confer susceptibility and a lifetime risk of breast. Several morphological and clinical features have been attributed to hereditary tumors. However, in sporadic breast cancer, the interrelationship between the loss of heterozygosity (LOH) of these loci and clinical features remains to be fully elucidated. METHODS: Microdissected paraffin-embedded tissue blocks of 48 cases of surgically resected breast carcinoma were investigated to identify the LOH of BRCA1 and BRCA2 using microsatellite markers. RESULTS: Of 48 cases, 22 (45.9%) exhibited LOH at BRCA1 locus while in 29 out of 48 (60.4%) cases LOH was observed for the BRCA2 region. There was no significant correlation between LOH at BRCA1/2 and the patient's age, tumor size, histologic grade or lymph node metastasis. When comparing the frequency of LOH with the expression of several prognostic factors, such as p53, c-erb B2 protein, estrogen and progesterone receptor using immunohistochemical stain, there was only correlation with LOH at BRCA2 and the progesterone receptor. CONCLUSIONS: Our results suggest that allelic deletion play a role to the development of sporadic breast cancers.

Hemorrhagic radiation proctitis is infrequently seen in patients receiving pelvic irradiation. The treatment of hemorrhagic ralation proctitis is often difficult. Many patients need reyeated hospitalizations and blood transfusions. Occasionally patiets will develop severe or recurrent rectal bleeding. In case of massive bleeding requiring excessive transfusion, colonic diversion by construction of a colostomy or excision of the diseased segment may be inevitable. However, surgical procedures in these patients are associated with a high mortality and morbidity. Moreover, medical therapy is usually ineffective. Recently formalin therapy has been introduced as a simple and effective treatment for hemorrhagic radiation proctitis. We experienced a 69 year-old woman patient who developed severe homorrhagic proctitis 1 year after radiotherapy for carcinoma of the cervix. She had not improved by conservative management and required blood tranafusions and repetitive hospitalizations. After local application of a 4% formalin solution in the diseased rectum under caudal anesthesia, the bleeding immediately stopped and the patient was discharged from the hospital, and no recurrence has been observed until now.

BACKGROUND: Type 2 diabetes is usually preceded by a long and clinically silent period of increasing insulin resistance. The purpose of this study is to demonstrate that rosiglitazone and metformin fixed-dose combination therapy (RSG/MET) will safely and effectively control glycemia as a first line of oral therapy, better than rosiglitazone (RSG) or metformin (MET) monotherapy in Korean type 2 diabetes patients. METHODS: This study was a 32-week, multicenter, randomized, double-blind study. Twenty-seven type 2 diabetes patients (males 14; females 13) were included and randomly divided into the rosiglitazone, metformin group, or rosiglitazone /metformin combination groups. The primary objective of this study was to determine the change in HbA1c from baseline (week 0) to week 32. The secondary end-points were to determine changes in fasting plasma glucose (FPG) and homeostasis model assessment insulin resistance (HOMA-IR), from baseline to week 32. Other cardiovascular risk markers were also assessed. RESULTS: At week 32, there were significant reductions in HbA1c and FPG, in all three treatment groups. There was no statistical difference in HbA1c among the three groups, but the decrease in FPG in the RSG/MET group was statistically significant compared to the MET group (P < 0.05). RSG/MET significantly reduced HOMA-IR at week 32 compared to baseline, but there was no difference among the three groups. RSG/MET significantly decreased high-sensitive C-reactive protein (hs-CRP) value at week 32, compared to baseline. There were increases in adiponectin from baseline to week 32 in the RSG and RSG/MET groups, and the increase in the RSG/MET group was statistically significant compared to that of the MET group (P < 0.05). At week 32, there was a significant decrease in plasminogen activator inhibitor-1 (PAI-1) in all three treatment groups, but no statistically significant difference among them. The RSG/MET group significantly decreased in terms of urinary albumin-creatinine ratio at week 32, compared to baseline. CONCLUSIONS: In this study, rosiglitazone and metformin combination therapy was effective in glycemic control as an initial therapy, and it improved cardiovascular risk markers in Korean type 2 diabetes patients.

PURPOSE: Laparoscopy-assisted distal gastrectomy (LADG) is gaining wider acceptance as a minimally invasive treatment for early gastric cancer. Generally; LADG, with extraperigastric lymph node dissection, is considered a technically more complicated procedure for gastric cancer than a conventional open distal gastrectomy (CODG). LADG, with extraperigastric lymph node dissection, for gastric cancers has previously been described, but the safety, efficacy and clinical benefits of these types of surgery are still unclear. To evaluate the short-term surgical validity, surgical outcome of a LADG, with extraperigastric lymph node dissection, was compared with that of a CODG in early gastric cancer patients. METHODS: A retrospective study of 80 patients with early gastric cancer (EGC), who underwent a LADG, with extraperigastric lymph node dissection, between September 2004 and August 2006, at Keimyung University Dongsan Medical Center, was performed. Over the same period, conventional open gastrectomies were performed in 97 patients, confirmed to have EGC from their pathology. Various clinicopathological parameters were evaluated from the medical records. RESULTS: The baseline characteristics, including gender, age, body mass index (BMI) and tumor size, were similar between the two groups. In the LADG group, the operation time was longer (P=0.000), but the blood loss was less (P=0.000) than in the CODG group. The postoperative recovery in the LADG group was faster, as reflected by the shorter time to pass gas and the shorter hospital stay, which resulted in significantly lower serum white blood cell count amylase and C-reactive protein levels on day 1. Pathological examinations showed the surgery to be equally radical in the two groups. CONCLUSION: According to this study; LADG, with extraperigastric lymph node dissection, is a safe and technically feasible procedure for the treatment of early gastric cancer. The LADG procedure provides several advantages to that of a conventional open distal gastrectomy; less inflammatory reactions, a rapid return of gastrointestinal function and a shorter hospital stay, with no decrease in the operative curability.

Background: The angular stable locking system (ASLS) was developed to provide additional stability to the distal interlocking screw of the intramedullary (IM) nail. Effects of ASLS on the treatment of femoral diaphyseal fractures in the elderly remain unknown. The aim of this study was to compare radiological outcomes of IM nailing using ASLS screws to IM nails with conventional interlocking screws in elderly patients with femoral shaft fractures. Methods: A multicenter retrospective review of 129 patients (average age, 73.5 years; 98 women and 31 men) aged 65 years or older who underwent IM nail fixation for femoral diaphyseal fractures (AO/Orthopaedic Trauma Association [OTA] classification 32) was conducted. Demographic information of patients, fracture site (subtrochanteric or shaft), fracture type (traumatic or atypical), and AO/OTA fracture classification were investigated. Reduction status was evaluated by postoperative plain radiography. Presence of union and time to union were evaluated through serial plain radiograph follow-up. Reoperation due to nonunion or implant failure was also evaluated. Results: ASLS was used in 65 patients (50.3%). A total of 118 patients (91.5%) achieved union without additional surgery and the mean union time was 31.8 ± 13.0 weeks. In terms of reduction status, angulation was greater in the group using ASLS. There were no statistically significant differences of union rate, time to union, and reoperation rate according to the use of ASLS (p > 0.05). There was no difference in the outcomes according to the use of ASLS even when the analysis was divided in terms of fracture site or fracture type (p > 0.05). In further subgroup analysis, only the traumatic subtrochanteric area group showed statistically significantly shorter time to union when ASLS was used (p = 0.038). Conclusions In geriatric patients with femoral diaphyseal fractures, the use of ASLS was not considered to have a significant effect on fracture healing. Fracture healing seemed to be more affected by surgical techniques such as minimizing the gap and fracture characteristics such as atypical femoral fractures, rather than implants.

Background: Sedentary behavior (SB) has emerged as a new risk factor for cardiovascular accidents. We investigated whether physical activity levels or SB were related to percent body fat (%BF) in type 2 diabetes mellitus (T2DM). Methods: In this cross sectional study, we measured the duration of SB, light physical activity (LPA), moderate to vigorous physical activity (MVPA), total energy expenditure, and step counts using a wireless activity tracker (Fitbit HR; FB) for 7 days in freeliving conditions, along with %BF using a bio impedance analyzer (Inbody; Biospace) in 120 smartphone users with T2DM. Subjects were divided into exercise (Exe, n=68) and non-exercise (nonExe, n=52) groups based on self-reports of whether the recommended exercises (30 min/day, 3 days/week for 3 months) were performed. SBt, LPAt, MVPAt were transformed from SB, LPA, MVPA for normally distributed variables. Results: Participants were: female, 59.2%; age, 59.3±8.4 years; body mass index, 25.5±3.4 kg/m2; glycosylated hemoglobin (HbA1c), 7.6%±1.2%; %BF, 30.4%±7.1%. They performed SB for 15.7±3.7 hr/day, LPA for 4.4±1.7 hr/day, and MVPA for 0.9±0.8 hr/day. The %BF was related to SBt and LPAt, but not to MVPA after adjustments for age, gender, and HbA1c. VPA was significantly higher in the Exe group than in the nonExe group, but SB, LPA, and moderate physical activity were not different. Predicted %BF was 89.494 to 0.105 (age), –13.047 (gender), –0.507 (HbA1c), –7.655 (LPAt) (F[4, 64]=62.929, P<0.001), with an R2 of 0.785 in multiple linear regression analysis. Conclusion Reduced body fat in elderly diabetic patients might be associated with reduced inactivity and increased LPA.
