RESUMEN

OBJECTIVE: There is a need to increase patient and clinician awareness on the effectiveness of pneumococcal vaccination in at-risk groups. The aim of the study was to evaluate the effect of reminders for physicians and patients using the vaccination tracking system created in the hospital information management system (HIMS) on the vaccination rate, and the effect of pneumococcal vaccination on pneumonia-related hospitalization and mortality over a 12-month period. MATERIAL AND METHODS: This prospective observational cohort study was undertaken during a 2-year period in 3 tertiary care centers. Patients were followed up for 12 months following vaccination, and hospital admissions and mortality were recorded via HIMS. During the campaign, HIMS transmitted pneumococcal immunization reminder messages in accordance with guideline recommendations to physicians' computers and patients' mobile phones. Educational posters on pneumococcal vaccination were posted in outpatient clinics. Regular seminars on the evidence for pneumococcal vaccination were organized. All patients who were hospitalized during the follow-up period for chronic obstructive pulmonary disease (COPD), asthma, lung cancer, or pneumonia were analyzed in relation to their vaccination history regarding clinical outcomes. RESULTS: A total of 29530 patients were included in the study. During the study period, the annual vaccination rate increased by 74.4% and reached 4.8% in 3 hospitals (P = .001). The rates were 3.9% in patients older than 65 years without comorbidities and 5.2% in those with COPD and asthma (P = .002). In pneumococcal vaccine recipients, pneumonia-related hospital mortality was lower (relative risk (RR) = 0.19, CI 0.09-0.35, P < .001). CONCLUSION: It is possible to raise the rate of pneumococcal vaccination through awareness campaigns. Individuals with COPD and asthma are more willing to receive pneumococcal vaccination. Among patients hospitalized for pneumonia, prior pneumococcal vaccination is associated with lower mortalit.

RESUMEN

Background: Although studies suggest a deficiency in stem cell numbers in chronic airway diseases such as chronic obstructive pulmonary disease (COPD), the role of bronchial epithelial progenitor/stem (P/S) cells is not clear. The objectives of this study were to investigate expression of progenitor/stem (P/S) cell markers, cytokeratin (CK) 5, CK14 and p63 in bronchial epithelial explants and cell cultures obtained from smokers with and without COPD following multiple outgrowths, and to study this effect on bronchial epithelial cell (BEC) proliferation. Methods: Bronchial epithelial explants were dissected from lung explants and cultured on coverslips. Confluent cultures were obtained after 3-4 weeks' (transfer, Tr1), explants were then transferred and cultured for a second (Tr2) and third (Tr3) time, respectively. At each stage, expression of CK5, CK14 and p63 in explants and BEC were determined by immunostaining. In parallel experiments, outgrowing cells from explants were counted after 4wks, and explants subsequently transferred to obtain new cultures for a further 3 times. Results: As the transfer number advanced, CK5, CK14 and p63 expression was decreased in both explants and BEC from both smokers without COPD and patients with COPD, with a more pronounced decrease in BEC numbers in the COPD group. Total cell numbers cultured from explants were decreased with advancing outgrowth number in both groups. Smoking status and lung function parameters were correlated with reduced P/S marker expression and cell numbers. Conclusion: Our findings suggest that the number of P/S cells in airway epithelium may play a role in the pathogenesis of COPD, as well as a role in the proliferation of airway epithelial cells, in vitro.

RESUMEN

OBJECTIVE: The most common histopathological subtype of lung cancer is adenocarcinoma. MicroRNAs are a class of non-coding RNAs that play roles in the regulation of gene expression. MicroRNAs affecting apoptosis may have different roles in lung adenocarcinoma development, progression, and differentiation. The objective of this study is to profile all known microRNAs linked to apoptosis in normal and lung cancer tissue using real-time polymerase chain reaction. MATERIAL AND METHODS: Tissues with adenocarcinoma and healthy tissues were taken from the same lung. The degree of differentiation of all tumors was determined. Expressions of 84 apoptosis-associated microRNAs in both tissues were analyzed by real-time polymerase chain reaction array. RESULTS: Eleven patients and 22 samples were included in the study. In the comparison of expression levels of apoptosis-associated microRNAs in normal and adenocarcinoma tissue, miR-134, miR-183-5p, miR-192-5p, miR-193b-3, miR-194-5p, miR-200c-3, miR212-3p, miR-25-3p, miR-449a, and miR-9-5p showed significant difference in downregulation. Receiver operating characteristic curve analysis of 10 identified microRNAs was performed, and cut-off values, sensitivity, and specificity were determined. No significant difference was found between microRNA expression levels in adenocarcinoma tissues classified as moderate-well to poorly differentiated. CONCLUSION: Differently, downregulated expressed apoptosis-associated microRNAs were detected in lung adenocarcinoma tissues. MicroRNAs can be used as biomarkers in the diagnosis in lung adenocarcinoma. The expression of microRNAs linked to apoptosis should be investigated in different lung cancer histological subtypes in order to identify potential biomarkers.

RESUMEN

OBJECTIVE: It is known that inpatient hospital costs are much higher than outpatient services. It was aimed to investigate the effect of pneumococcal vaccination on hospitalizations. MATERIAL AND METHODS: The direct hospitalization costs, length of stay, and factors of the vaccinated and unvaccinated patients in the same hospital during the 12-month follow-up of the patients who received pneumococcal vaccine between November 15, 2018, and November 15, 2020, in 3 chest diseases and thoracic surgery training and research hospitals were analyzed by obtaining Hospital Information Management System records. Data were collected with Statistical Package for the Social Sciences version 23 program (IBM Corp.; Armonk, NY, USA) , and statistical evaluation was made. RESULTS: The mean age of 800 hospitalized patients, of whom 400 were unvaccinated and 400 were vaccinated, was 68.48 ± 11.97. There was no significant difference in the mean age of vaccinated and unvaccinated patients (P > .05). Five hundred sixty-six patients (70.8%) were aged 65 and over. Two hundred eighty (51.2%) of men were vaccinated and 120 (47.2%) of women were vaccinated, and there was no significant difference (P > .05). The mean hospital stay of these patients was 11.01 days, and those in the vaccinated group had an average mean hospital stay of 9.11 days and those in the unvaccinated group had a mean hospital stay less than 12.91 days (P < .001). Total 1-year hospitalization costs were $501.653.53 and the cost per person was calculated as $627.07. The cost per capita for the vaccinated group was $550.52, which was lower than the average cost of the unvaccinated group ($703.62) (P < .05). When comparing the status of being vaccinated, comorbidity, mortality, mean length of stay, chronic obstructive pulmonary disease, and heart disease were found to be statistically significant (P < .05). CONCLUSION: In our study, it was revealed that vaccination of patients hospitalized in chest disease hospitals with the pneumococcal vaccine reduced the average length of hospital stay by 41.7% and the cost of hospitalization by 27.8%.

RESUMEN

The COVID-19-related death rate varies between countries and is affected by various risk factors. This multicenter registry study was designed to evaluate the mortality rate and the related risk factors in Turkey. We retrospectively evaluated 1500 adults with COVID-19 from 26 centers who were hospitalized between March 11 and July 31, 2020. In the study group, 1041 and 459 cases were diagnosed as definite and highly probable cases, respectively. There were 993 PCR-positive cases (66.2%). Among all cases, 1144 (76.3%) were diagnosed with non-severe pneumonia, whereas 212 (14.1%) had severe pneumonia. Death occurred in 67 patients, corresponding to a mortality rate of 4.5% (95% CI:3.5-5.6). The univariate analysis demonstrated that various factors, including male sex, age ≥65 years and the presence of dyspnea or confusion, malignity, chronic obstructive lung disease, interstitial lung disease, immunosuppressive conditions, severe pneumonia, multiorgan dysfunction, and sepsis, were positively associated with mortality. Favipiravir, hydroxychloroquine and azithromycin were not associated with survival. Following multivariate analysis, male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were found to be independent risk factors for mortality. Among the biomarkers, procalcitonin levels on the 3rd-5th days of admission showed the strongest associations with mortality (OR: 6.18; 1.6-23.93). This study demonstrated that the mortality rate in hospitalized patients in the early phase of the COVID-19 pandemic was a serious threat and that those patients with male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were at increased risk of mortality; therefore, such patients should be closely monitored.

RESUMEN

PURPOSE: There is still an evident need for useful biomarkers and effective therapeutic approaches regarding the challenging management of sepsis. The aim of the study is to evaluate the effect of each Cytosorb hemoadsorption therapy course on blood levels of inflammatory biomarkers of sepsis including endocan, copeptin, interleukin-6, procalcitonin, C-reactive protein. METHODS: There were a total of 178 samples belonging to 34 patients that were diagnosed with sepsis and undergone Cytosorb therapy during the study period. Patient demographics were recorded. Arterial blood samples were obtained both before and and after each Cytosorb course. Levels of copeptin, interleukin-6, procalcitonin, C-reactive protein, erythrocyte sedimentation rate, white blood cell count, and creatinine were assessed both before and after each Cytosorb treatment. RESULTS: Levels of endocan, copeptin, interleukin-6, procalcitonin, C-reactive protein, and erythrocyte sedimentation rate were all significantly decreased after the Cytosorb course when compared with levels before therapy (p = 0.039, 0.001, 0.010, 0.001, 0.002 and 0.001, respectively). There was no significant difference between white blood cell count and creatinine levels before and after Cytosorb courses (p = 0.204 and 0.277). CONCLUSION: Cytosorb courses achieved significant decreases in endocan, copeptin, interleukin-6, procalcitonin and C-reactive protein levels. Decreasing plasma levels of inflammatory cytokines may help alleviate the cytokine storm and may have a role in improve outcomes. Further prospective randomized controlled studies with larger sample size are needed concerning the long-term effects of this decrease in cytokine levels on outcome and mortality.

RESUMEN

BACKGROUND: This study aims to investigate the prognostic factors that affect survival rates and durations in patients with T3 non-small cell lung cancer who underwent surgery. METHODS: A total of 129 patients with T3 n on-small c ell l ung c ancer (125 males, 4 females; mean age 60±9.3 years; range 23 to 80 years) who were performed surgery in our clinic between January 1997 and December 2013 were evaluated retrospectively in terms of age, gender, type of resection, tumor histopathology, tumor, node and metastasis staging, lymph node invasion, chemotherapy and radiotherapy, and recurrence. RESULTS: During the evaluation, while 61 patients (47.3%) were alive, 68 (52.7%) had lost their lives. One-, two- and five-year survival rates of the study population were 79.8%, 56.9% and 23.2%, respectively. Mean duration of survival was 41.5±4.0 months (range 33.7-49.4 months). Patient's age or tumor histopathology did not affect the duration of survival. Overall duration of survival was significantly longer in patients of stage IIB, patients who had low stages of lymph node invasion, who were performed lobectomy, who received chemotherapy or radiotherapy or who were without recurrence (p<0.05 for each). Multivariate regression analysis revealed that lymph node invasion, presence of recurrence or pneumonectomy, or failure to have been administered chemotherapy increased mortality risk significantly (hazard ratios 0.217, 3.369, 2.791 and 2.254, respectively). CONCLUSION: Our findings revealed that lymph node invasion, presence of recurrence or pneumonectomy, or failure to have been administered chemotherapy are poor prognostic factors in T3 non-small cell lung cancer. Prognostic factors should be taken into consideration during treatment and follow-up periods of patients with T3 non-small cell lung cancer.

RESUMEN

PURPOSE: Sorafenib, a multikinase inhibitor, is effective in patients with advanced hepatocellular carcinoma (HCC). Transarterial chemoembolization (TACE) is an important palliative treatment for unresectable HCC, but TACE-induced ischemic injury can upregulate angiogenic factors and it might be associated with poor prognosis. The purpose of this study was to evaluate the efficacy of conventional TACE with or without sorafenib in patients with Barcelona Clinic Liver Cancer (BCLC) stage A-B HCC. METHODS: Thirty patients with BCLC stage A or B HCC who had undergone TACE were enrolled in this retrospective study. Child-Pugh score, BCLC staging classification, size and number of lesions were recorded. Sorafenib was given 1 month after TACE to some patients who responded to TACE. Repeated TACE was performed on demand. Tumor response was assessed every 12 weeks. The primary objective of this trial was the progression free survival (PFS). Secondary objectives were overall survival (OS), disease control rate (DCR) and total number of TACE interventions. Kaplan-Meier method was used for the estimation of survival and survival curves were compared with Log-rank test. RESULTS: Twenty-five (83.3%) patients had Child-Pugh A and 5 (16.7%) Child-Pugh B, and 24 (80%) patients had BCLC stage B disease and remanining had stage A disease. Lesion size >10 cm was found in 6 patients and 16/7/7 patients had single/two/multiple lesions, respectively. Mean number of TACE was 2.10±1.369. Seventeen (56.7%) patients used sorafenib after TACE whereas 13 (43.3%) patients were followed without any treatment but received consequent TACEs if needed. PFS of all patients was 10 months (range 3-48); it was 13 months for TACE plus sorafenib group and 9 months for TACE group (p=0.081). In subgroup analysis, TACE plus sorafenib group had better PFS (36 vs 12 months) in patients with tumor size > 10 cm (p=0.025). In the analysis of Child- Pugh A cases, PFS of TACE plus sorafenib group was 23 months while it was 10 months in TACE group (p=0.007). CONCLUSION: Concurrent treatment in Child-Pugh A group HCC with conventional TACE and sorafenib demonstrates a significant efficacy in patients having tumor size >10 cm. In Child-Pugh A group, PFS was superior in the sorafenib plus TACE group than in TACE alone group.

RESUMEN

BACKGROUND/AIM: For the early stage of nonsmall-cell lung cancer, surgical resection provides the best survival, but the surgical risk generally increases with age because of the increased prevalence of comorbidities, especially cardiovascular disorders. The aim of this study was to compare survival and mortality rates of two groups with different ages, younger and older than 70 years, who went curative resection for nonsmall-cell lung cancer. MATERIALS AND METHODS: We analyzed the patients who underwent curative lung cancer surgery in the Department of Thoracic Surgery of Gaziantep University Research Hospital between January 1997 and November 2014. Patients were divided into 2 groups according to their ages. RESULTS: A total of 497 patients were included in data analysis (381 were under 70 years old and 116 of them were ≥70 years old). The older group showed a 1.4-fold increased risk of mortality hazard ratio when the probability of survival was analyzed by histological type, lymph node involvement, disease stage, and age. CONCLUSION: There was no distinct increase in 30-day mortality rates of patients with nonsmall-cell lung cancer who were ≥70 years old, but the hazard rate for long-term survival was higher in the older group. Curative pulmonary resections due to lung cancer should be carefully performed in septuagenarians.

RESUMEN

OBJECTIVE: Nasal Polyp (NP) is a benign mass of the paranasal sinuses that protrudes into the nasal cavity. The exact underlying pathogenesis is not known. In this study we aimed to determine the genetic susceptibility of NP formation in relation to TNF-α-308 and IL-1ß-511 promoter region gene polymorphisms. METHODS: A total of 71 patients with NP with asthma (n=21) or without asthma (n=50) were taken as the study group, and 91 healthy volunteers were taken as the control group. Blood was gathered into EDTA-containing tubes, and patient DNA was extracted. The polymorphisms of the IL-ß and TNF-α cytokine genes were analyzed using real time polymerase chain reaction. RESULTS: The GG genotype in the TNF-α-308 region and the CC genotype in the IL-1ß-511 region were found to be risk factors for NP formation (OR: 9.2, p=0.007 and OR: 33.3, p=0.001, respectively). Regarding allelic frequencies, the G allele at the TNF-α-308 promoter region was a risk factor for NP formation (OR: 6.06, p<0.001). CONCLUSION: TNF-α GG genotype in the -308 promoter region and the IL-1ß CC genotype in the -511 region are genetic risk factors for NP formation.

RESUMEN

AIM: The aim of this study is to analyse the effect of delayed diagnosis on mortality rates, and evaluate the role of delayed diagnosis as a new prognostic factor in patients with oesophageal atresia (OA), especially in developing countries. METHODS: The records of 80 consecutive patients with OA (2008-2013) were reviewed. Patients were divided into two groups according to the time of diagnosis. As we demonstrated the effect of delayed diagnosis on mortality, we decided to develop a new classification that will be utilised to predict the prognosis of OA. The discrimination ability of the new prognostic classification was compared with those of the Waterston, Montreal and Spitz classifications using the area under the curve. RESULTS: The parameters of the new prognostic classification were birth weight less than 2000 g, the presence of major cardiac/life-threatening anomalies and delay in diagnosis. Class I consisted of patients with none or one of these parameters. Class II consisted of patients with two or three of these parameters. The area under the curve of the new classification was better than those of the other classifications in determining the prognosis of patients with OA. CONCLUSIONS: Delayed diagnosis of OA significantly led to morbidity and mortality. Although delayed diagnosis is not a characteristic of newborn or a marker of severity for OA and is a health care system issue in developing countries, we here point out that it is a prognostic factor in its own right. Our new classification has a superior discriminatory ability compared to the above-mentioned classifications.

RESUMEN

PURPOSE: The aim of this study is to clarify the relationship between recurrence risk of breast cancer and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms. PATIENTS AND METHODS: Breast cancer patients who had undergone surgery in Gaziantep University Oncology Hospital between June 2005 and June 2012 were followed-up and retrospectively enrolled in this study. Blood samples were collected from all patients to assess MTHFR C677T polymorphisms. Stage according to tumor-node-metastasis system, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 status, grade of disease, menopausal status, and administered chemotherapy or hormonal therapy were recorded. Effects of these parameters on recurrence risk were evaluated using univariate analysis and multivariate binary logistic regression model. RESULTS: Association of MTHFR C677T polymorphisms with recurrence risk was evaluated in 298 patients whose median age was 47 years (range: 21-79 years). In all patients, age (odds ratio [OR] =0.953, P=0.005) and N3 lymph node status (OR =6.293, P=0.001) were found to affect the recurrence risk. While MTHFR homozygote genotype did not have an effect on recurrence risk in all patients, increased risk was observed in lymph node-positive subgroup (OR =4.271; 95% CI 1.515-12.023; P=0.006). Adjusting for age, tumor size (T), and node status (N), MTHFR homozygote genotype had more statistically significant risk for recurrence (OR =3.255; 95% CI 1.047-10.125; P=0.041). CONCLUSION: MTHFR TT genotype was found to be associated with increased recurrence risk in patients with lymph node-positive breast cancer.

RESUMEN

Interleukin-1 beta (IL-1ß), IL-6, tumour necrosis factor-alpha (TNF-α) and epidermal growth factor (EGF) play important roles in the wound healing process. In the present study, human wound specimens (n = 50) were collected from cases of death due to injuries from firearms, penetrating trauma by sharp objects and blunt trauma with a known time of injury and death identified by forensic autopsy. Full-thickness tissue specimens were obtained from injured skin sites, and equally sized intact tissues obtained from the same person were used as controls. Protein determination was performed using ELISA according to the Bradford method for each specimen, and results were provided for individual proteins. IL-1ß levels did not reach statistical significance in any of the wound groups and were not markedly higher than those in the control group. However, IL-6 showed a biphasic pattern and reached statistical significance in the group with wounds less than 30 min old and in the group with wounds more than 18 h old. IL-6 was consistently higher in all wound groups than in the control group. TNF-α showed a statistically significant increase within the first 30 min and remained at a high level in all groups except for those with wounds 2-4 h old. On the other hand, EGF was high in all groups excluding those with wounds 2-4 h old and more than 18 h old, but statistical significance was not reached. Our results suggest that IL-6 and TNF-α in particular may be used as early-phase markers. We believe that IL-1ß and EGF should be more extensively evaluated in further studies.

RESUMEN

BACKGROUND: Interindividual variability of pharmacogenetics may account for unpredictable neurotoxicities of taxanes. METHODS: From March 2011 to June 2015, female patients with operable breast cancer who had received docetaxel- or paclitaxel-containing adjuvant chemotherapy were included in this study. All patients were treated with single-agent paclitaxel intravenously (IV) 175 mg/m(2) every 3 weeks for four cycles, or IV 80 mg/m(2) weekly for 12 cycles, and IV 100 mg/m(2) docetaxel for four cycles as adjuvant treatment. We evaluated the relationship between neurotoxicity of taxanes and single-nucleotide polymorphisms of ABCB1, CYP3A4, ERCC1, ERCC2, FGFR4, TP53, ERBB2, and CYP2C8 genes. Taxane-induced neurotoxicity during the treatment was evaluated according to the National Cancer Institute Common Toxicity Criteria version 4.03 prior to each cycle. Chi-squared tests were used to compare the two groups, and multivariate binary logistic regression models were used for determining possible risk factors of neuropathy. RESULTS: Pharmacogenetic analysis was performed in 219 females. ABCB1 3435 TT genotype had significantly higher risk for grade ≥2 neurotoxicity (odds ratio [OR]: 2.759, 95% confidence interval [CI]: 1.172-6.493, P: 0.017) compared to TC and CC genotype, and also CYP3A4 392 AA and AG genotype had significantly higher risk for grade ≥2 neurotoxicity (OR: 2.259, 95% CI: 1.033-4.941, P: 0.038) compared to GG genotype. For FDGF4 gene with AG and GG genotype, OR was 1.879 (95% CI: 1.001-3.525, P: 0.048) compared to AA genotype with regard to any grade of neuropathy risk. We could not find any other association of other genotypes with neurotoxicity grades. CONCLUSION: ABCB1 3435 TT genotype and CYP3A4 392 AA/AG genotypes may be used as predictors of neurotoxicity during taxane chemotherapy.

RESUMEN

PURPOSE: The number of patients who make it to receive third-line chemotherapy is increasing owing to the improvements in adverse-event management of chemotherapy for small-cell lung cancer (SCLC). Sequencing of optimal treatment for SCLC is still a challenge for oncologists. In this paper, we aim to present a different approach to the treatment of SCLC. METHODS: Between January 2008 and July 2014, all patients diagnosed with extensive-stage SCLC and treated with third-line chemotherapy at Gaziantep University Oncology Hospital were analyzed retrospectively. Disease control rates and progression-free survival (PFS) for first-, second-, and third-line chemotherapy, and overall survival (OS) were recorded. Survival analysis was calculated by using Kaplan-Meier method. RESULTS: A total of 255 SCLC patients were screened, and 25 of those patients who received third-line chemotherapy were included in this study. Median age was 57±10.131 years (range: 39-74 years). Disease control rates at first-, second-, and third-line chemotherapy were 92%, 68%, and 44%, respectively. Fourteen patients received irinotecan followed by topotecan, and eleven patients received topotecan followed by irinotecan. Second-line median PFS was statistically better in patients treated with irinotecan at second-line compared with those treated with topotecan (21 vs 12 weeks, P=0.018). Comparison of third-line median PFS of the two groups was not statistically significant (14 vs 12 weeks, P=0.986). Median OS was not statistically significant in patients who received irinotecan followed by topotecan vs those who received topotecan followed by irinotecan (18 vs 14 months, P=0.112). CONCLUSION: Sequential monotherapy with topotecan and irinotecan provides a considerable contribution to OS, and second-line irinotecan showed a better PFS, despite a similar OS, compared with topotecan.

RESUMEN

BACKGROUND: Oxaliplatin and taxane-induced neurosensory toxicity is dose-limiting and mostly presents with acute symptoms that affect the activities of daily living and overall quality of life. The objective of the present study is to assess the relief of acute neuropathy with venlafaxine treatment during the chemotherapy period. PATIENTS AND METHODS: In this retrospective case-control study, from January 2010 to February 2015, patients who experienced treatment with oxaliplatin and taxane-induced acute neurotoxicity were evaluated according to the NCI-CTCAE v. 4.03 grading scale. Neurotoxicity was evaluated using a numeric rating scale (NRS) for pain intensity and experienced relief under the treatment of venlafaxine and using a neuropathic pain symptom inventory scale (NPSI) for the style of complaints. Patients who were diagnosed as mildly depressed according to the HOST anxiety and depression scale and who had grade 1 to 3 sensory neurotoxicity based on the NCI-CTCAE v. 4.03 grading scale, and who also reported ≥ 4/10 on a NRS were eligible. The primary end point was the rate of more than 75 % symptomatic relief under venlafaxine treatment. RESULTS: Two hundred six patients were included (82 % female, median age: 52.7 years). Most patients had breast, gynecologic, and colon cancer (93.4 %). Ninety-one patients who received venlafaxine and 115 patients as the control group were assessed for neurotoxicity every 3 weeks. Based on the NRS, a rate of more than 75 % symptomatic relief was 53.5, 58.3, and 45.2 % in venlafaxine arm versus 0, 0, and 0 % in the control arm in the first, second, and third visits, respectively. Side-effects of venlafaxine (n = 7) were grade 1-2 nausea/vomiting (3.2 %) and asthenia/somnolence (3.2 %) without grade 3-4 events. CONCLUSION: Venlafaxine has a significant clinical activity against taxane-oxaliplatin-induced acute neurosensory toxicity.

RESUMEN

PURPOSE: The purpose of this study was to determine whether the presence of diabetes mellitus (DM) influences the incidence and severity of peripheral sensory neuropathy (PSN) in patients using taxane therapy. METHODS: A retrospective single-center analysis was conducted: Patients with PSN at baseline were excluded. The incidence of PSN was evaluated retrospectively in patient subgroups who received taxane arm and taxane-plus-platinum-agents combination arm with or without known DM at baseline. RESULTS: Three hundred seventy-four patients were enrolled in this study, 81 (21.6%) of patients had DM at baseline. The incidence of grade 1 PSN (non-DM/DM) in patients receiving taxane-based chemotherapy was 33.4/25.9% and more than grade 2 PSN (non-DM/DM) was 15/34.6%. The rate of neuropathy of non-diabetic patients was 48.8%, while the rate of diabetic patients was 52.8 and 75% in DM duration below 5 years and above 5 years group, respectively. CONCLUSIONS: This retrospective analysis indicates that taxane-based therapy in DM patients whose disease duration is above 5 years appears to affect the incidence and severity of PSN without known baseline neuropathy. The probability of PSN with taxane-based therapy was similar in DM duration below 5 years and non-DM patients.

RESUMEN

The aim of this study was to identify clinical factors that can predict malignancy in patients with persistent cervical lymphadenopathy. This retrospective study included 575 patients with persistent cervical lymphadenopathy who underwent surgical excision. The patients were divided into two groups according to their ages: group 1 (≤18 years) and group 2 (>18 years). Multiple logistic regression models and univariate analysis were performed to determine the association between clinical factors and malignancy. Male gender [odds ratio (OR) 4.184, 95 % confidence interval (CI) 1.823-9.602, p = 0.001], increased age (OR 1.072, 95 % CI 1.001-1.148, p = 0.046), left-sided lesions (OR 3.423, 95 % CI 1.407-8.329, p = 0.007), and larger lymph node size (OR 1.445, 95 % CI 1.021-2.044, p = 0.038) were significantly associated with malignancy in group 1. Male gender (OR 3.761, 95 % CI 2.361-5.992, p = 0.001), increased age (OR 1.015, 95 % CI 1.003-1.027, p = 0.018), duration of the disease (OR 0.770, 95 % CI 0.668-0.888, p = 0.001), and the presence of B symptoms (OR 4.996, 95 % CI 2.862-8.721, p = 0.001) were significantly associated with malignancy in group 2. The sensitivity and specificity of the models were 84 and 61.5 % for group 1 and 77.9 and 67.9 % for group 2, respectively. Increasing age and male gender were found to be associated with malignancy in all age groups. Larger lymph node size and left-sided lymphadenopathy were significant predictors of malignancy in children. Presence of B symptoms was found to be associated with malignancy in adults. Our results indicated that increasing duration of lymphadenopathy and the presence of bilaterality render the lymph node more likely to be benign in adults. No significant association was found between the involved neck site and malignancy for all age groups.

RESUMEN

The aim of this study was to investigate the effectiveness and safety of selective neck dissection in patients with lymph node-positive head and neck squamous cell carcinoma to determine regional control and survival rates. Eighty patients with lymph node-positive head and neck squamous cell carcinoma who underwent selective dissection were included in the study. Regional control, survival rates, and factors affecting survival were analyzed. Regional control was 90%, disease-specific survival was 93.4%, and the overall survival rate was 87.25%. T stage, N stage, age, and extracapsular spread were included in hazard regression models. None of the factors were statistically significant. Selective neck dissection is an effective and oncologically safe treatment option in selected cases. T stage, N stage, and extracapsular spread had no significant impact on disease-specific survival.

RESUMEN

Although several factors such as cigarette smoking, blood pressure, diabetes, obesity, hypercholesterolemia, physical inactivity and dietary factors have been well documented to increase the risk for stroke, there are conflicting data about the role of meteorological variables in the etiology of stroke. We conducted a retrospective study to investigate the association between weather patterns, including daily temperature, humidity, wind speed, and air pressure, and stroke admissions to the Emergency Department of Atatürk Training and Research Hospital in Ankara, Turkey, between January 2009 and April 2010. Generalized additive models with logistic link function were used to investigate the relationship between predictors and days with and without stroke admission at lags 0-4. A total of 373 stroke patients were admitted to the emergency department (ED) between January 2009 and April 2010. Of patients, 297 had ischemic stroke (IS), 34 hemorrhagic stroke (HS), and 42 subarachnoidal hemorrhage (SAH). Although we did not find any association between overall admissions due to stroke and meteorological parameters, univariable analysis indicated that there were significantly more SAH cases on days with lower daily mean temperatures of 8.79 ± 8.75 °C as compared to relatively mild days with higher temperatures (mean temperature = 11.89 ± 7.94 °C, p = 0.021). The multivariable analysis demonstrated that admissions due to SAH increased on days with lower daily mean temperatures for the same day (lag 0; odds ratio (OR) [95% confidence interval (95% CI)] = 0.93 [0.89-0.98], p = 0.004) and lag 1 (OR [95% CI] =0.76 [0.67-0.86], p = 0.001). Furthermore, the wind speed at both lag 1 (OR [95% CI] = 1.63 [1.27-2.09], p = 0.001) and lag 3 (OR [95% CI] = 1.43 [1.12-1.81], p = 0.004) increased admissions due to HS, respectively. In conclusion, our study demonstrated that there was an association between ED admissions due to SAH and HS and weather conditions suggesting that meteorological variables may, at least in part, play as risk factors for intracranial hemorrhages.
