RESUMO
BACKGROUND: One-fifth of COVID-19 patients are seriously and critically ill cases and have a worse prognosis than non-severe cases. Although there is no specific treatment available for COVID-19, early recognition and supportive treatment may reduce the mortality. The aim of this study is to develop a functional nomogram that can be used by clinicians to estimate the risk of in-hospital mortality in patients hospitalized and treated for COVID-19 disease, and to compare the accuracy of model predictions with previous nomograms. METHODS: This retrospective study enrolled 709 patients who were over 18 years old and received inpatient treatment for COVID-19 disease. Multivariable Logistic Regression analysis was performed to assess the possible predictors of a fatal outcome. A nomogram was developed with the possible predictors and total point were calculated. RESULTS: Of the 709 patients treated for COVID-19, 75 (11%) died and 634 survived. The elder age, certain comorbidities (cancer, heart failure, chronic renal failure), dyspnea, lower levels of oxygen saturation and hematocrit, higher levels of C-reactive protein, aspartate aminotransferase and ferritin were independent risk factors for mortality. The prediction ability of total points was excellent (Area Under Curve = 0.922). CONCLUSIONS: The nomogram developed in this study can be used by clinicians as a practical and effective tool in mortality risk estimation. So that with early diagnosis and intervention mortality in COVID-19 patients may be reduced.

AIM: An important life-threatening complication of intensive chemotherapy administered in children with leukemia is febrile neutropenia. The objective of this study was to evaluate the clinical features and consequences of febrile neutropenia attacks in children who were treated for acute lymphoblastic leukemia. MATERIAL AND METHODS: Nighty-six children who received chemotherapy for acute lymphoblastic leukemia in our center between January 1995 and December 2010 were included in the study. The data related to demographic characteristics, treatment features, relapse and febrile neutropenia incidences, risk factors, culture results and prognosis were retrospectively evaluated from the patients' files. RESULTS: A total of two hundred-ninety nine febrile neutropenia attacks observed in the patients during initial treatment and relapse treatment were evaluated. When the incidence of febrile neutropenia was evaluated by years, it was observed that the patients treated after year 2000 had statistically significantly more febrile neutopenia attacks compared to the patients treated before year 2000. When the incidences of febrile neutropenia during initial treatment and during relapse treatment were compared, it was observed that more febrile neutropenia attacks occured during relapse treatment. Fifty-nine percent of all febrile neutropenia attacks were fever of unknown origin. Eighty microorganisms grew in cultures during febrile neutropenia throughout treatment in 75 patients; 86% were bacterial infections (50% gram positive and 50% gram negative), 8% were viral infections and 6% were fungal infections. Coagulase negative staphylococcus (n=17) was the most frequent gram positive pathogen; E. Coli (n=17) was the most commonly grown gram negative pathogen. CONCLUSIONS: In this study, it was found that an increase in the incidence of febrile neutropenia occured in years. Increments in treatment intensities increase the incidence of febrile neutropenia while improving survival. Evaluation of febrile neutropenia results by hematology-oncology units in years will be directive in early and successful treatment.
RESUMO
AIM: The aim of this cross-sectional study was to determine the prevalence of the self reported health behaviors and differences in these behaviors by gender and grades in high school adolescents in Izmir, Turkey. MATERIAL AND METHODS: A stratified cluster sampling procedure was used for this cross-sectional study. The study sample included 2 296 students attending 22 high schools in Izmir. As a data collection instrument, some questions from the Health Behavior in School-aged Children Study 2009/2010 questionnnaire and questions which were developed by the researchers to understand behaviors of internet use in adolescents were used. Chi-square tests and Cramer's V statistics were used for statistical analyses. RESULTS: Among the high school students, 33.8% experimented smoking, 26.3% smoked cigarette during the 30 days before the survey, 14.9% smoked cigarette regularly during the 30 days before the survey, 54.1% experimented drinking alcohol, 38.4% drunk alcohol during the 30 days before the survey, 31.6% got drunk, 10.9% were adequately physically active, 59.9% watched TV for a long period of time, 72.8% used internet for a long period of time, 48.1% ate breakfast regularly, 36.2% ate adequate amount of fruit, 14.1% ate adequate amount of vegetable, 31.3% ate candies and chocolate very often, 18% drunk soft drink very often, 30.3% were bullied, 29.9% bullied others and 41% involved in a physical fight. CONCLUSIONS: These results showed that "Adolescent friendly health services" should be generalized all over Turkey, physicians should evaluate each adolescent for his/her health behaviors in each visit and implementation of prevention programs which adopt a health promotion perspective is necessary begining from the elementary school.
RESUMO
Immune thrombocytopenia (ITP) is an acute self-limited disease of childhood, mostly resolving within 6 months irrespective of whether therapy is given or not. Treatment options when indicated include corticosteroids, intravenous immune globulin (IVIG), and anti-RhD immunoglobulin. We reviewed our 32 years' experience for first-line therapy of acute ITP. Five hundred forty-one children (mean age: 5.3 years) diagnosed and treated for ITP were evaluated retrospectively. Among 491 acute ITP patients, IVIG was used in 27%, high-dose steroids in 27%, low-dose steroids in 20%, anti-D immunoglobulin G (IgG) in 2%, and no therapy in 22%. When the initial response (platelets >50 × 10(9)/L) to first-line treatment modalities were compared, 89%, 84%, and 78% patients treated by low-dose steroids, high-dose steroids, and IVIG responded to treatment, respectively (P > .05). Mean time to recovery of platelets was 16.8, 3.8, and 3.0 days in patients treated with low-dose steroids, high-dose steroids, and IVIG, respectively (P < .0001). Thrombocytopenia recurred in 23% of low-dose steroid, 39% of high-dose steroid, and in 36% of IVIG (P < .0001) treatment groups. Of 108 patients who were observed alone, 4 (3%) had a recurrence on follow-up and only 2 of these required treatment subsequently. Recurrence was significantly less in no therapy group compared with children treated with 1 of the 3 options of pharmacotherapy (P < .0001). Response rates were similar between patients treated by IVIG and low- and high-dose steroids; however, time to response was slower in patients treated with low-dose steroids compared with IVIG and high-dose steroids.

OBJECTIVE: Hemorrhoids are normal elements of the anal canal anatomy and they become symptomatic with potential factors such as gravity or strain. When symptomatic, hemorrhoidal disease can be costly measured in time away from productive activities. The aim of the study was to assess changes in the quality of life of patients after hemorrhoidectomy using Short Form-36. MATERIAL AND METHODS: Thirty patients, 24 male and 6 female (age 28 to 65), who were diagnosed with grade III and IV internal hemorrhoidal disease at the general surgery outpatient clinic and treated with stapled hemorrhoidectomy were enrolled in the study. They filled out Short Form-36 a week before surgery and four weeks after surgery. Post-Hoc tests were evaluated with Bonferroni correction after Kruskal Wallis analysis. Wilcoxon test, Student-t-test and Mann-Whitney U test were used for statistical analysis using SPSS 15. RESULTS: Physical health (Physical functioning, Physical role restriction, Bodily pain) scores were significantly improved after surgery. CONCLUSION: Success of hemorrhoidectomy operations can be evaluated by postoperative recovery, incidence of complications or relapses. Quality of life questionnaires are another method to evaluate the success of the treatment from the patient's perspective.

AIM: To compare the quality of the 2008 cancer mortality data of the Istanbul Directorate of Cemeteries (IDC) with the 2008 data of International Agency for Research on Cancer (IARC) and Turkish Statistical Institute (TUIK), and discuss the suitability of using this databank for estimations of cancer mortality in the future. METHODS: We used 2008 and 2010 death records of the IDC and compared it to TUIK and IARC data. RESULTS: According to the WHO statistics, in Turkey in 2008 there were 67255 estimated cancer deaths. As the population of Turkey was 71517100, the cancer mortality rate was 9.4 per 10000. According to the IDC statistics, the cancer mortality rate in Istanbul in 2008 was 5.97 per 10000. CONCLUSION: IDC estimates were higher than WHO probably because WHO bases its estimates on a sample group and because of the restrictions of IDC data collection method. Death certificates could be a reliable and accurate data source for mortality statistics if the problems of data collection are solved.

BACKGROUND: The aim of the present study was to investigate the effect of different doses of vitamin C on oxidative liver injury due to isoniazid (INH) in rats. METHODS: Rats were divided into four subgroups, each containing 10 rats. Group 1 was the control group; group 2, INH 50 mg/kg per day; group 3, INH 50 mg/kg per day + low-dose vitamin C (100 mg/kg per day); group 4, INH 50 mg/kg per day + high-dose vitamin C (1000 mg/kg per day). INH and vitamin C were administered into their stomachs through an oral tube. After 21 days, measurements were made in both serum and homogenized liver tissues. The levels of glutathione (GSH), superoxide dismutase (SOD) and other biochemical variables were measured. Malondialdehyde (MDA), glutathione peroxidase (GSH-px) and vitamin C were measured using commercial kits. RESULTS: Aspartate amino transferase and alanine aminotransferase in group 2 were higher than those in groups 1, 3 and 4 (P < 0.008 for both). Serum and tissue levels of MDA in group 2 were higher than that in groups 1 and 3 (P < 0.008 for both). There was no difference in the SOD levels between the four groups (P= 0.095). Erythrocyte and tissue GSH in group 2 were higher than that in groups 1 and 3 (P < 0.008 for both). Interestingly, erythrocyte and tissue GSH in group 4 were lower than those in group 1 (P < 0.008 for both). Erythrocyte level of GSH-px in group 2 was higher than that in groups 1 and 3 (P < 0.008 for both). CONCLUSIONS: INH-induced liver injury is associated with oxidative stress, and co-administration of low-dose vitamin C may reduce this damage effectively in a rat model. The antioxidant effect of high-dose vitamin C does not seem more potent compared to the low dose.

BACKGROUND: The purpose of this study was to provide data about the prevalence of violent behaviour among high school students living in Istanbul and to determine the correlates of physical fighting. METHOD: This study involved the completion of a modified version of 'Health Behaviour in School Age Children (HBSC) 1997/1998' survey questionnaire by 4153 grade 9-11 students. Chi square tests and forward stepwise multiple logistic regression models were used for statistical analyses. RESULTS: During the last 12 months preceding the survey 42% of students (n=1720) reported that they had been in a physical fight; 7% (n=274) reported that they were involved in a fight which required medical treatment. During the last school term 19% (n=768) bullied others at school; 30% (n=1255) reported having been bullied at school; 7% (n=309) reported that they had been bullied with a weapon on school grounds; 8% (n=346) reported that they carried a weapon on school grounds. In logistic regression analyses being male, poor mental health score, being sexually active, current cigarette use, illicit drug use, not using seat belts, bullying, being bullied with a weapon, carrying a weapon, spending more time with friends, poor school image and physical abuse were found to be associated with fighting. CONCLUSION: Violent behaviour is common in high school students. There is a strong need for violence prevention programmes in schools.

UNLABELLED: The objective of this study was to investigate health status of Turkish adolescents and to determine the factors affecting their self perceptions of health. The subjects of the study were 4,153 grade 9-11 students from 26 randomly selected high schools in Istanbul. In total, 78% (n = 3231) and 62% (n = 2537) of the students reported that they were feeling healthy and happy, respectively. Prevalence of headache, abdominal pain and backache; feeling low, irritable, nervous and dizzy; medication use for headache, abdominal pain and nervousness were higher in females than in males (P < 0.05 for each comparison). Prevalence of difficulty in getting to sleep and medication use for it were quite similar in both genders. Perceived higher socio-economic status, feeling happy and exercising longer than 2-3 h a week were found as protective factors related to feeling healthy for both genders. In females, ease of talking to mother and perceived adequate parental support on school matters and in males, ease of talking to father and satisfaction with body size were protective factors related to feeling healthy, respectively. Cigarette smoking and having headaches put feeling healthy at risk in both genders. In females, feeling left out of things, having backache and dizziness and medication use for nervousness and in males, feeling pressured by school work, abdominal pain and difficulty in getting to sleep were risk factors related to feeling healthy, respectively. CONCLUSION: the findings of this study suggest that a significant number of Turkish adolescents perceive themselves as not very healthy and experience psychosomatic symptoms. Perception of health differed to some extent according to gender. Programmes promoting health-related activities and coping strategies with parental participation need to be developed for improving health in high school students.

BACKGROUND: The aim of the present study was to determine the prevalence, associated symptoms, and clinical outcomes of children with acute abdominal pain who had been admitted to an emergency department. METHODS: Children aged between 2 and 16 years who presented to the emergency department of Cerrahpasa Medical School, Istanbul University between July 2001 and August 2002 with acute abdominal pain were enrolled in this study. A questionnaire was completed each patient admitted to our pediatric emergency unit for acute abdominal pain. Data collected included presenting signs and symptoms, the hospital follow up for all children who returned within 10 days, test results, and telephone follow up. RESULTS: The number of children referred to the emergency department was 7442, with 399 (5.4%) of these having acute abdominal pain. The mean age of the study population was 6.9 +/- 3.5 years, and 201 of the patients were male. The five most prevalent diagnoses were: (i) upper respiratory tract infection and/or complicated with otitis media or sinusitis (23.7%); (ii) abdominal pain with uncertain etiology (15.4%); (iii) gastroenteritis (15.4%); (iv) constipation (9.4%); and (v) urinary tract infection (8%). The most common associated symptoms were decreased appetite, fever and emesis. Because of follow-up deficiency the progress of 28 patients was not obtained. Eighty-two children were referred to the department of pediatric surgery, but only 17 of 82 (20.7%) required surgical intervention (15 of these 17 for appendicitis). Eleven patients returned within 10 days for re-evaluation, but the initial diagnosis was not changed. The complaints of 57 patients with uncertain etiology were resolved within 2 days. CONCLUSIONS: An acute complaint of abdominal pain was usually attributed to a self-limited disease. However, the percentage of surgical etiology is not negligible.

The aim of this study was to evaluate the prevalence, behavioral patterns and correlates of regular alcohol drinking in high school students. This cross-sectional study involved the completion of a modified version of "Health Behavior in School Age Children" (HBSC 1997/1998) questionnaire by 4,153 grade 9-11 students from 26 randomly selected high schools in Istanbul. Chi-square test, Spearman correlation test and forward stepwise multiple logistic regression model were used for statistical analyses as appropriate. Overall, 61% of students were experimental drinkers, and 46% of the students were current drinkers. There was a significant difference between female and male students with respect to reporting current alcohol drinking at grade 9 and 11 (p > 0.05 for each comparison). Regular drinking was reported by 6% of students. Male students were more likely than female students to report regular drinking at each grade (p < 0.01 for each comparison). Nineteen percent of the students reported that they had been really drunk at least once during their lifetime. Malestudents were more likely than female students to report an occasion of drunkenness at each grade (p < 0.05 for each comparison). All types of drinking behavior rates tended to increase across grades for both genders (p < 0.05 for each comparison). In logistic regression analysis the following were all independently associated with regular drinking: being in grade 11, smoking cigarettes currently, lifetime drug use, bullying others, being sexually active, playing computer games > or = 4 h/week, exercising < or = 1 h/week, spending > or = four evenings with friends, at ease in talking to same gender friends, tiredness in the morning, perceived as good-looking/beautiful, higher educational level of the mother and perceived poor academic achievement. The results of this study showed that alcohol consumption is prevalent among high school students. There is therefore a need for school-based alcohol prevention programs which also deal with family and peer influences on drinking.

In the experimental stress literature, the results of investigations have not shown a specific sex-dependent vulnerability to stress ulceration. The aim of this study was to evaluate the importance of sex differences on stress ulcer development. Related to gender, the contributing factors for stress ulcer production such as luminal acidity, sialic acid as an marker of gastric mucosal protection, oxygen (O2)-derived free radicals and endogenous antioxidant defence mechanisms were also investigated. Fifty Wistar Albino rats weighing about 230 g and aged 7 or 8 months were divided equally into five groups: Group I normal male rats, group II castrated male rats, group III normal female rats in estrus phase, group IV normal female rats in diestrus phase and group V castrated female rats. Cold restraint model was used for 6 hours to produce stress ulcer. No statistically significant difference was found out between groups in view of gross and histopathologic damage. There was no significant difference between groups according to gastric luminal acidity, gastric mucosal sialic acid, gastric malonaldehyde (MDA) and catalase values. Gastric superoxide dismutase (SOD) activity was significantly lower in Group I in comparison to those of Group III and IV. Sex differences do not interfere stress ulcer formation. SOD activity in rat gastric tissue has varied significantly by hormonal milieu.
