RESUMEN
OBJECTIVE: Past three years since the beginning of the outbreak, we have obtained satisfactory data on COVID-19. However, data on risk factors of COVID-19-associated coagulopathy (CAC) are extremely limited. Prediction of CAC might be a game changer since it is related to poor prognosis. Seeking independent risk factors for CAC was the main aim of the study. PATIENTS AND METHODS: 510 hospitalized COVID-19 patients were retrospectively screened. Forty-eight of them were excluded due to irrelevant D-dimer or ferritin elevation. The remaining patients were stratified into three groups as overt coagulopathy, significant pulmonary microthrombosis, and patients without coagulopathy. The overt coagulopathy group included cases with macrothrombosis or disseminated intravascular coagulation (DIC). The significant pulmonary microthrombosis group covered the cases that had clinical deterioration with simultaneous marked D-dimer elevation. The group of patients without coagulopathy included the asymptomatic patients with normal or elevated D-dimer levels. RESULTS: Overt coagulopathy developed in 3.2% and significant pulmonary microthrombosis in 10.1% of the patients. In the multivariate analysis, not receiving low molecular weight heparin (LMWH) (p=0.002), a level of D-dimer >15,000 U/ml (p=0.013) were associated with overt coagulopathy. In addition, levels of initial LDH >480 IU/L (p=0.022) and initial ferritin >1,000 ng/ml (p=0.036) were associated with significant pulmonary microthrombosis. Not receiving LMWH (p=0.001) was also associated with significant pulmonary microthrombosis, when multivariate analysis was performed by the parameters with a p-value <0.1 in the univariate analysis. Furthermore, all cases with DIC had Gram-negative bacterial sepsis. CONCLUSIONS: Not receiving LMWH, high levels of D-dimer, initial LDH, and initial ferritin are independent risk factors for CAC. DIC does not appear to develop based on COVID-19.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide and presents critical challenges for public health. Due to its chronic and systemic course, COVID-19 is currently accepted as a multi-systemic infectious disease. Here we explore the possible association between disease course and hereditary thrombotic factors and comorbidities. PATIENTS AND METHODS: The patients admitted to the COVID-19 center in the Istanbul Faculty of Medicine were recruited for the study. The patients were classified according to the clinical course, severe vs. mild. Five polymorphic loci were analyzed by multiplex PCR: Factor V Leiden (FVL), FII G20210A, Beta-fibrinogen G-455A, and methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C. RESULTS: FII G20210A and Beta-fibrinogen G-455A genotypes were significantly higher in the study group compared to the literature. Wildtype genotype (GG) in Factor V Leiden locus was significantly associated with low D-Dimer levels (p =0.013). The GA genotype increased the D-Dimer levels 2.55-times compared to the GG genotype (p =0.003). Moreover, the Beta-fibrinogen G-455G genotype was significantly higher in the LDH>250 group (p =0.046). CONCLUSIONS: The presence of solid tumors in patients with COVID-19 was related to the severity of the disease course. No evidence of a correlation between the severity of the disease and all five thrombotic mutations was found, whereas the FII G20210A and Beta-fibrinogen G-455A mutations were significantly high compared to previously reported Turkish population data and global carrier rates. This finding will need to be verified by further studies with larger samples since it may reflect a likelihood of having the COVID-19 disease. The high carrier frequency of FVL mutation was more likely present in the D-dimer high group generating an increase in the D-dimer levels 2.55-times compared to the wildtype.

OBJECTIVE: Vitamin D has beneficial effects, some of which involve the cardiovascular system. No study to date has investigated the association between serum endocan levels, as a biomarker of endothelial inflammation, and vitamin D levels in the absence of subclinical atherosclerosis detected by carotid intima-media thickness (CIMT) in healthy individuals. PATIENTS AND METHODS: Subjects were categorized into three groups based on vitamin D levels according to Endocrine Society guidelines. Mean CIMT was calculated from six measurements on two scans. Statistical significance was set at p < 0.05, and all testing was two-sided. RESULTS: The concentration of serum endocan was 802.8 ± 411.4 ng/L in the group with the lowest serum vitamin D level, 454.8 ± 334.3 ng/L in the mild/moderately low serum vitamin D level group, and 269.4 ± 180.2 ng/L in the group with normal serum vitamin D levels (p < 0.01). Receiver operating characteristics curve analysis revealed that a serum vitamin D concentration of 7.5 ng/mL had a 97% sensitivity and 81% specificity for the prediction of serum endocan level greater than 270 ng/L, which could be an indicator for endothelial inflammation. CONCLUSIONS: Demonstrating that vitamin D deficiency can cause endothelial damage in the early period of atherosclerosis without the development of clinical cardiovascular disease will have a pivotal role in the prevention of cardiovascular mortality and morbidity.

This study was conducted to compare the long-term oncological outcomes of laparotomy and laparoscopic surgeries in endometrial cancer under the light of the 2016 ESMO-ESGO-ESTRO risk classification system, with particular focus on the high-intermediate- and high-risk categories. Using multicentric databases between January 2005 and January 2016, disease-free and overall survivals of 2745 endometrial cancer cases were compared according to the surgery route (laparotomy vs. laparoscopy). The high-intermediate- and high-risk patients were defined with respect to the 2016 ESMO-ESGO-ESTRO risk classification system, and they were analyzed with respect to differences in survival rates. Of the 2745 patients, 1743 (63.5%) were operated by laparotomy, and the remaining were operated with laparoscopy. The total numbers of high-intermediate- and high-risk endometrial cancer cases were 734 (45%) patients in the laparotomy group and 307 (30.7%) patients in the laparoscopy group. Disease-free and overall survivals were not statistically different when compared between laparoscopy and laparotomy groups in terms of low-, intermediate-, high-intermediate- and high-risk endometrial cancer. In conclusion, regardless of the endometrial cancer risk category, long-term oncological outcomes of the laparoscopic approach were found to be comparable to those treated with laparotomy. Our results are encouraging to consider laparoscopic surgery for high-intermediate- and high-risk endometrial cancer cases.

PURPOSE OF THE STUDY The objective of the present study is to compare the efficacy of two different concentrations of diclofenac sodium phonophoresis (DSPH) (1.16% vs 2.32%) in patients with knee osteoarthritis (OA). MATERIAL AND METHODS A randomized, double-blind, controlled design was applied. Ninety patients (mean age± SD, 59.98 ± 8.89 years) who had Kellgren-Lawrence (K-L) grades II to III knee OA were randomly allocated into three groups; 1.16% DSPH, 2.32% DSPH, TUS (30 in each group). Each patient was treated five sessions per week for two weeks. A 100-mm visual analogue scale (VAS) for usual pain and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were evaluated before and after treatment in all groups. RESULTS The VAS pain and WOMAC scores were significantly improved after treatment in all groups (p < 0.05). The 2.32% DSPH showed more significant effects than the 1.16% DSPH, both in improving WOMAC- pain and physical function scores (p = 0.020, p = 0.008) and reducing the VAS pain measure, although it did not reach the level of significance (p = 0.077). The 2.32% DSPH was superior to the TUS, both in reducing the VAS pain measure (p < 0.001) and in improving WOMAC-pain, stiffness, physical function and total scores (p = 0.022, p = 0.016, p < 0.001, p < 0.001 respectively). 1.16% DSPH significantly reduced stiffness and physical function scores compared with TUS (p = 0.042, p = 0.047). CONCLUSIONS DSPH and TUS are effective treatments for knee OA. Our results indicated that 2.32% DSPH produces additional benefits to functional improvement and pain reduction compared with 1.16% DSPH in K-L grades II to III knee OA. Key words: diclofenac sodium, knee osteoarthritis, phonophoresis, therapeutic ultrasound, topical formulation.

AIM: Mucopolysaccharidosis type III B (MPS IIIB) is an autosomal recessive lysosomal storage disease caused by mutations in the NAGLU gene which codes the lysosomal enzyme alpha-N-acetylglucosaminidase. The major symptoms of the disease are cognitive and neurological defects. In this study, the molecular spectrums of 13 MPS IIIB patients were evaluated. MATERIAL AND METHODS: Thirteen MPS IIIB patients from 11 families were included in this study. All patients were both clinically and molecularly diagnosed. NAGLU gene sequencing was performed using a next generation sequencing platform (Illumina MiSeq). Demographic, clinical and laboratory findings of the patients were obtained via the hospital records. RESULTS: Ten different mutations from the 13 MPS IIIB patients were identified. Eight of the 10 mutations were missense, one was splice site, and one large deletion was also observed. Two mutations c.509G>T (p.Gly170Val) and c.700C>G (p.Arg234Gly) have been defined for the first time in this study. CONCLUSION: Our study expanded the mutation spectrum of the NAGLU gene thereby contributing to the improved genetic counselling of MPS IIIB patients. Confirming the literature, missense mutations were also found to be the most common NAGLU mutations in our study.
RESUMEN
Background: Postoperative pain is an important problem for patients undergoing shoulder surgery. Our study investigated analgesic efficacy, duration of analgesia, postoperative analgesic use and patient satisfaction with the use of preemptive intravenous dexketoprofen for interscalene block in addition to general anesthesia in arthroscopic shoulder surgery. Methods: 60 patients, scheduled for arthroscopic shoulder surgery were randomized (30 patients each) into either: - control group (Group1) or dexketoprofen group (Group 2). Patients were followed for 48 hours to compare both groups for; post-operative pain scores, effectiveness of postoperative analgesia, duration of analgesia, and analgesia consumption. Duration of postoperative sensory block of the shoulder joint was defined as time to onset of pain at the incision site. Duration of postoperative motor block of the shoulder joint was defined as time to onset of first shoulder movement. Results: While no significant difference was determined for motor block time, sensory block time was significantly longer in the dexketoprofen group (p < 0.05).VAS scores were significantly lower at all times in the dexketoprofen group (p < 0.05).Total PCA fentanyl consumption was 274.16 ± 314.89 (µg) in the dexketoprofen group, and 490.00 ± 408.98 (µg) in the control group, the difference was statistically significant (p < 0.05). No significant difference was observed between the groups' demographic and hemodynamic data. Conclusion: Pre-emptive IV dexketoprofen may be a good option for arthroscopic shoulder surgery and provides effective analgesia.

OBJECTIVE: Older adults have been continuously reported to be at higher risk for adverse outcomes of Covid-19. We aimed to describe clinical characteristics and early outcomes of the older Covid-19 patients hospitalized in our center comparatively with the younger patients, and also to analyze the triage factors that were related to the in-hospital mortality of older adults. DESIGN: Retrospective; observational study. SETTING: Istanbul Faculty of Medicine hospital, Turkey. PARTICIPANTS: 362 hospitalized patients with laboratory-confirmed Covid-19 from March 11 to May 11, 2020. MEASUREMENTS: The demographic information; associated comorbidities; presenting clinical, laboratory, radiological characteristics on admission and outcomes from the electronic medical records were analyzed comparatively between the younger (<65 years) and older (≥65 years) adults. Factors associated with in-hospital mortality of the older adults were analyzed by multivariate regression analyses. RESULTS: The median age was 56 years (interquartile range [IQR], 46-67), and 224 (61.9%) were male. There were 104 (28.7%) patients ≥65 years of age. More than half of the patients (58%) had one or more chronic comorbidity. The three most common presenting symptoms in the older patients were fatigue/myalgia (89.4%), dry cough (72.1%), and fever (63.5%). Cough and fever were significantly less prevalent in older adults compared to younger patients (p=0.001 and 0.008, respectively). Clinically severe pneumonia was present in 31.5% of the study population being more common in older adults (49% vs. 24.4%) (p<0.001). The laboratory parameters that were significantly different between the older and younger adults were as follows: the older patients had significantly higher CRP, D-dimer, TnT, pro-BNP, procalcitonin levels, higher prevalence of lymphopenia, neutrophilia, increased creatinine, and lower hemoglobin, ALT, albumin level (p<0.05). In the radiological evaluation, more than half of the patients (54.6%) had moderate-severe pneumonia, which was more prevalent in older patients (66% vs. 50%) (p=0.006). The adverse outcomes were significantly more prevalent in older adults compared to the younger patients (ICU admission, 28.8% vs. 8.9%; mortality, 23.1% vs. 4.3%, p<0.001). Among the triage evaluation parameters, the only factor associated with higher mortality was the presence of clinically severe pneumonia on admission (Odds Ratio=12.3, 95% confidence interval=2.7-55.5, p=0.001). CONCLUSION: Older patients presented with more prevalent chronic comorbidities, less prevalent symptomatology but more severe respiratory signs and laboratory abnormalities than the younger patients. Among the triage assessment factors, the clinical evaluation of pulmonary involvement came in front to help clinicians to stratify the patients for mortality risk.

OBJECTIVE: Type 1 cardiorenal syndrome (CRS) is an acute renal failure in patients with acute decompensated heart failure with an incidence of 24% to 45%. The aim of our study was to investigate the significance of new renal biomarkers to predict type 1 CRS. PATIENTS AND METHODS: The study included 111 patients with acute decompensated heart failure diagnosed at the Istanbul Medical Faculty Emergency Department between 2014 and 2016, and 24 healthy volunteers. All urine samples were stored at -80°C after centrifugation. Samples were run according to the instructions of TIMP-2, ILGF-7, KIM-1, and IGFBP-7 ELISA kits. Diuretic treatments were then administered with intravenous administration of at least 80 mg furosemide per day. Follow-up biochemical and spot urine specimens were taken after 72 hours. For statistical analysis, SPSS version 21.0 statistical software was used. Significance was evaluated at p<0.05. RESULTS: The baseline creatinine level was measured as 1.33 ± 0.39 mg/dL in the heart failure group. It was seen that 67% (75) of the patients had increased creatinine levels and developed type 1 CRS. ILGF-7, TIMP-2, and (ILGF-7 * TIMP-2) values were significantly higher in patients with cardiorenal syndrome when we separated the two groups as patients with and without cardiorenal syndrome (0.40 (0.25-0.71), p1: 0.049/2.40 (1.42-3.70), p2: 0.003/1.15 (0.29-2.43), p3: 0.001). CONCLUSIONS: Renal tubular markers reveal promising developments in the pathophysiology of cardiorenal syndrome in light of recently obtained data. Renal tubular biomarkers may have the potential to be a predictor of heart failure and cardiorenal syndrome.

AIM: To constitute accurate policies for reducing the cesarean section (C/S) the authors evaluated the attitudes and knowledge of health workers and public population towards the mode of delivery, C/S on demand, and delivery complications in a large population. MATERIALS AND METHODS: 1,892 female volunteers in reproductive age were enrolled in the study and 589 of them were health workers. Patients were evaluated with questionnaire about their delivery mode and their answers were analyzed. RESULTS: The overall cesarean rate of the study population was 45.4%. This rate were 51.4% and 28.2%, respectively, for the health workers and public group (p < 0.001). Medical indication ratio ivere 57.7% and 40.1% for the healthcare group and the public population respectively and 20.2% of health workers and 13.9% of the public group had C/S by their preference without any medical indications (p < 0.001). CONCLUSION: C/S rate is high in Turkey and an action plan is needed to decrease the rate. When a patient's preference towards the mode of the delivery is C/S on demand, obstetricians, in their capacity as patient advocate, should help guide their patient through the sophisticated detailed medical information toward a decision that respects both the patient's attitude and the physician's obligation to optimize the health of both the mother and the newborn.

OBJECTIVE: Acute pulmonary embolism (APE) is a very common disease that must be diagnosed and treated quickly and accurately to reduce significant morbidity and mortality rates. Acute pulmonary embolism is associated with numerous electrocardiographic (ECG) changes including prolonged QT interval with global T-wave inversion. The aim of the study was to investigate the relationship between the T-wave peak-to-end interval and diagnosis of APE, which has never been investigated in the literature. PATIENTS AND METHODS: Seventy-three patients who were suspected of having APE took part in the present study. The Local Ethics Committee of Istanbul University, Turkey, approved the study protocol. Forty-one of the patients were diagnosed as having APE using computed tomography. Surface ECGs were taken in the initial assessment at admission. The Tp-Te interval was identified as the interval from the peak of the T-wave to the end of the T-wave. The measurements of the Tp-Te interval were taken using precordial leads. All measurements were compared using appropriate statistical tests. Statistical analysis was performed using SPSS version 22.0. RESULTS: We enrolled 73 patients to the study, 41 of which were diagnosed as having APE. Men comprised 54% of the APE group. The mean ages in the APE (+) and APE (-) groups were 59.5 ± 14.5 years and 61±9.2 years, respectively. There was a significant increase in Tp-Te results in V1 (p<0.01). The Tp-Te interval was 74.21 ± 20.81 in the APE (+) group, whereas it was 59.73 ± 12.82 in APE (-) group (p<0.01). CONCLUSIONS: Acute pulmonary embolism (APE) is a mortal condition and as such, rapid and accurate diagnosis is very important. Surface ECG can be used to measure Tp-Te in patients admitted to the emergency room with suspected APE in the differential diagnosis as a fast and easily accessible tool.

BACKGROUND: Infant mortality rate (IMR) and neonatal mortality rate (NMR) are accepted as good indicators to measure the health status of a nation. This report describes recent declines in IMR and NMR in Turkey. METHODS: Data on infants who died before 12 months of life were obtained from the Infant Mortality Monitoring System of Ministry of Health of Turkey between 2007 and 2012. A total of 94,038 infant deaths were evaluated. RESULTS: Turkey IMR and NMR exhibited a marked decline from 2007 (16.4 and 12.2) to 2010 (10.1 and 6.6) and then plateaued in 2012 (9.7 and 6.3), despite regional differences. Prematurity, congenital anomalies and congenital heart diseases (CHD) were the three most common causes of infant deaths between 2007 and 2012. While the rates of respiratory distress syndrome (RDS), sudden infant death syndrome (SIDS), and metabolic diseases increased, the rates of congenital anomalies and birth injuries decreased. IMR and NMR significantly increased with the number of infants per paediatrician, per doctor, and per midwife, while was decreasing with the increased rate of hospital birth, caesarean delivery, antenatal care, infant follow-up, and staff trained within the Neonatal Resuscitation Programme (NRP). CONCLUSION: From 2007-2012, Turkey showed remarkable encouraging advances in reducing IMR and NMR. Any interventions aimed at further reductions in IMR and NMR should target the common causes of death and defined risk factors especially in socioeconomically disadvantaged regions.

OBJECTIVE: The aim of the present study was to evaluate the time-dependent histopathologic changes in both ovaries and to determine the time-dependent levels of plasma interleukin 6 (IL-6) after unilateral ovarian torsion. MATERIALS AND METHODS: An experimental animal study included 48 female Sprague-Dawley rats which were distributed to six groups: control group (Group 1), sham-operated control group (Group 2), and four unilateral ovarian torsion groups with torsion duration of three, six, 12, and 24 hours (Group 3, 4, 5, and 6, respectively). Histopathologic criteria (follicular degeneration, vascular congestion, hemorrhage, inflammatory cell infiltration, and total tissue damage score) were evaluated in both ovaries, and plasma IL-6 levels were measured. RESULTS: At 24 hours after torsion began, mean total tissue damage score was similar between ovaries that had torsion and contralateral ovaries. Mean plasma IL-6 level did not change during the 24 hours after torsion began (p = 0.584). CONCLUSIONS: In addition to ovaries that had torsion, histopathologic abnormalities also occurred in contralateral ovaries. These results suggest that contralateral ovaries are not quiescent after unilateral ovarian torsion. Plasma IL-6 levels did not change significantly during the 24 hours after ovarian torsion began, resulting in a limitation of its diagnostic use in the early course of the disease.

Early and efficient detection of embryonic death (ED) has a valuable impact as important as early pregnancy diagnosis in ruminants. Among early pregnancy diagnosis methods, detection of the expression of interferon tau-stimulated genes (ISGs) in peripheral blood leukocytes (PBLs) is well documented in cows and ewes. Therefore, we hypothesized that the expression profile of ISGs in PBLs might also be useful for detecting ED in these animals. For this purpose, pregnant ewes were used as an experimental model. Pregnancy was detected on Day 18 after mating by transrectal ultrasonography. Pregnant ewes were divided into a control group (sham injection on Day 18, n = 10) and ED group (treated with 75 µg synthetic PGF2α on Day 18, n = 12). PBLs and plasma were collected on Days 0 (mating day), 15, 18, 19, 20, 21, 23, and 25 by jugular venipuncture. Total RNA was isolated from PBLs. ISGs expression levels were determined by real-time polymerase chain reaction in triplicate. Electrochemiluminescence immunoassay was used to measure progesterone (P4) levels in plasma. In the ED group, the P4 level declined to less than 1 ng/mL on Day 19 and remained at a low level until the end of the study. Compared with that on Day 0, receptor transporter protein 4 (RTP4) and ISG15 expression was upregulated on Day 15 and remained high until Day 21 in both groups, and RTP4 and ISG15 mRNA levels were attenuated on Days 23 and 25 only in the ED group (P < 0.001). Myxovirus resistance 1 expression was upregulated on Day 15 and remained high until Day 23 in both groups, but was attenuated on Day 25 in the ED group (P < 0.05). The B2-microglobulin mRNA level did not change significantly during the study in either group. These results indicate that the decline in P4 concentration was an immediate response to PGF2α and that the embryo may have survived longer than the CL on the basis of the extended period of ISGs expression. This suggests that the absence of P4 could be the reason for ED rather than a direct effect of PGF2α. In conclusion, the expression of ISGs, including ISG15, RTP4, and myxovirus resistance 1, but not B2-microglobulin, in PBLs may serve as a marker of ED.

OBJECTIVE: In this study, we aimed to demonstrate characteristics, recurrence rates, survival numbers, and factors associated with survival of patients with adult granulosa cell tumor (AGCT) from a single institution. Our secondary goal was to evaluate the necessity of staging surgery and the importance of a comprehensive lymphadenectomy in these patients. METHODS: The data of 158 patients in our institution who were diagnosed with AGCT between 1988 and 2013 were evaluated. The data were obtained from the files of the patients, electronic database of the gynecologic oncology clinic, operation notes, and pathology records. RESULTS: The median (range) age of the patients was 50.3 (22-82) years. The main symptom was postmenopausal bleeding (25.9%). Seventy-six percent of the patients underwent staging surgery including lymphadenectomy. Among these patients, 3 (2.5%) had lymph node metastasis. The median (range) follow-up time was 97 (1-296) months. In the follow-up period, 18 patients (12.5%) had recurrence. Menopausal status (P = 0.016), advanced age (P = 0.024), cyst rupture (P = 0.001), poorly differentiated tumor (P = 0.002), and advanced stage (P < 0.001) were associated with recurrence. Stage was the only independent prognostic factor for the development of recurrence. None of the patients had lymph node failure. CONCLUSIONS: In the present study with a long follow-up period and in which most of the patients had staging surgery including lymphadenectomy (76.6%), lymph node recurrence was not observed and the total recurrence rate (12.5%) was lower than that reported in the literature. The study showed the importance of surgical staging in patients with AGCT.

Cervical cancer (CC) is the most common gynaecological cancer during pregnancy. The rarity of the disease and lack of randomised control studies have prevented the establishment of treatment guidelines. The management of CC mainly follows the guidelines for the non-pregnant disease state, expert opinions and limited case reports. Although the management of CC diagnosed during pregnancy appears to be a significant dilemma for the patients and specialists, the prognosis of CC is not influenced by pregnancy. The treatment decision should be made collaboratively with a multidisciplinary team consisting of an obstetrician, gynaecologist, oncologist and paediatrician. The concerns of the patient should be taken into account.

BACKGROUND: We aimed to determine the frequency of early and late complications following groin surgery for vulvar cancer and analyze possible risk factors. MATERIALS AND METHODS: This retrospective cohort study included 99 women who underwent for vulvar cancer. The early (≤1 month) complications were wound infection, breakdown and lymphocyst and late (>1 month) complications were lower limb lymphedema, incontinence and erysipelas. The risk factors for developing each of the complications were analyzed with regression analysis. RESULTS: In the entire cohort, 29 (29.3%) women experienced early and 12 (12.1%) had late complications. Wound complications including infection and breakdown were the leading early complications (23.2%). In the multivariate analysis, both obesity (body mass index≥30 kg/m2) and advanced age (≥65 years) were found as independent predictive factors for early complications. Obese women of advanced age had 6.32 times more risk of experiencing any of the early complications, when compared to non-obese and young women (55.6% vs 8.7%). The most common late complication was lower limb lymphedema (10.1%) that was more frequently seen in young women. However, neither age nor lymph node count were significantly associated with the occurrence of lower limb lymphedema. CONCLUSIONS: More than 40% of the women suffered from postoperative complications after inguinofemoral lymphadenectomy in the current study. While advanced age and obesity were the significant predictors for any of the early complications, there was no identified risk factor for lower limb lymphedema.

This study aimed to determine the effects of parenteral selenium (Se) and vitamin E supplementation on economic impact, milk yield, and some reproductive parameters in high-yield dairy cows in the dry period and in those at the beginning of lactation. At the beginning of the dry period, cows (n = 323) were randomly divided into three groups as follows: Treatment 1 (T1), Treatment 2 (T2), and Control (C). Cows in group T1 received this preparation 21 days before calving and on calving day, and cows in group T2 received it only on calving day. The cows in the control group did not receive this preparation. Supplementation with Se increased Se serum levels of cows treated at calving day (p<0.05). Differences in milk yield at all weeks and the electrical conductivity values at the 8th and 12th weeks were significant (p<0.05). Supplementation with Se and Vitamin E decreased the incidence of metritis, the number of services per conception and the service period, but had no effects on the incidence of retained fetal membrane. A partial budgeting analysis indicated that Se supplementation was economically profitable; cows in group T1 averaged 240.6$ per cow, those in group T2 averaged 224.6$ per cow. Supplementation with Se and Vitamin E has been found to increase serum Se levels, milk yield, and has positive effects on udder health by decreasing milk conductivity values and incidence of sub-clinical mastitis.
RESUMEN
INTRODUCTION: The role of lymphadenectomy in the management of uterine leiomyosarcoma (LMS) is controversial. We aimed to identify whether lymph node dissection (LND) has any survival benefit in uterine LMS. METHODS: Data of 95 patients with histologically proven uterine LMS from 2 tertiary centers (1993 through 2009) were retrospectively analyzed. Kaplan-Meier and Cox proportional hazards regression models were used for analyses. RESULTS: Mean age was 51.5 years. Thirty-six (37.9%) underwent LND. The median lymph node count was 54. Eight (22.2%) patients had lymphatic metastasis. Median follow-up was 26 months. Sixty-two (65%) patients had recurrence and 48 (50.5%) died. Median disease-free survival (DFS) was 19 months for both group of patients who had or did not have LND, and median overall survival (OS) was 29 and 26 months, respectively (P = 0.4). Five-year DFS was 35.9% vs 26.8% (P = 0.4), and 5-year OS was 45.4% vs 43.8% (P = 0.22) for the groups. Multivariate analyses did not reveal a single independent prognostic factor in respect to DFS or OS. CONCLUSION: Higher rate of lymph node metastasis in patients with extrauterine disease indicated the importance of LND in LMS. However, the survival benefit of lymphadenectomy could not be shown.
