RESUMO

CONTEXT: Studies investigating the association between serum IGF-1, and thyroid nodule, ovarian or thyroid volume in polycystic ovarian syndrome (PCOS) are limited. OBJECTIVE: We aimed to analyze the association between serum IGF-1 level, and ovarian or thyroid volume, or thyroid nodule in PCOS. DESIGN: The study was performed between June 2017 and August 2019 as prospective design. SUBJECTS AND METHODS: Adult females with new-onset PCOS were included. The patients having comorbid illness, or using medication were excluded. Basic tests, thyroid and ovarian sonography were performed. The patients were grouped according to thyroid nodule(absent/present) and ovarian volume (<10mL/≥10mL). We planned to find a positive association between IGF-1, and thyroid nodule, thyroid or ovarian volume in PCOS. RESULTS: Of total 118 patients, 11(9%) had thyroid nodule. The patients with thyroid nodule had a higher ovarian volume (p=0.006). No correlation was found between GH or IGF-1, and thyroid or ovarian volume. IGF-1 was not a predictor for thyroid nodule or higher ovarian volume. Thyroid nodule was a significant predictor for higher ovarian volume. CONCLUSION: Our study is the first to analyze the association between IGF-1 and thyroid nodule in PCOS. We found that thyroid nodule was associated with thyroid and ovarian volume, but IGF-1 was not associated with thyroid nodule, thyroid or ovarian volume.

RESUMO

OBJECTIVE: To investigate whether there is any relationship between the clinical parameters and the histopathological features of the gallbladder (GB) specimens obtained from living liver donors (LLDs). METHODS: The demographic (age, sex, height, weight, and BMI), clinical (liver graft type, liver graft weight, and GB volume), microbiological (bile culture), and histopathological (width, length, wall thickness, and microscopic properties of the GB specimen) data of 169 LLDs, who underwent living donor hepatectomy between October 2015 and October 2017, were prospectively recorded and retrospectively analyzed. The LLDs were compared with respect to sex (male vs. female) and the histopathological features of the GB (normal structure vs. chronic cholecystitis vs. cholesterolosis/polyps/cholelithiasis). RESULTS: There were no significant differences between both sexes with respect to age, graft type, and some features of GB (volume, wall thickness, width, length, and bile culture). On one hand, there were significant differences between both sexes with regard to height (P < 0.001), weight (P < 0.001), BMI (P < 0.001), histopathological findings (P = 0.003), and graft size (P = 0.003). Comparison with regard to GB's histopathological features revealed no significant differences between the three groups with respect to age, weight, and some features of GB (volume, length, width, and bile culture). On the other hand, the three groups were significantly different in terms of sex (P = 0.003), height (P = 0.008), BMI (P = 0.002), and wall thickness (P = 0.044). Bile culture proliferation occurred in none of the patients except for one patient. CONCLUSION: This study is the first to assess GB's volume, dimensions, and bile culture in healthy individuals such as LLDs.

RESUMO

BACKGROUND AND OBJECTIVES: Psoriasis is a common, chronic, inflammatory, and hyperproliperative skin disease. It has been known that the infectious agents play a role in triggering and exacerbation of the disease. Periodontal diseases are chronic inflammatory gum diseases initiated by microorganisms in dental plaques. This study intended to determine the role of periodontal diseases, as chronic infective foci in psoriasis. MATERIALS AND METHODS: A total of 76 patients, who applied to Faculty of Medicine, Department of Dermatology, Inönü University, diagnosed as psoriasis and a control group consisting of 76 dermatologic patients without any systemic disease at similar age and gender were included the study. The dental examinations of the subjects were done by the Community Periodontal Index of Treatment Needs index system, using a periodontal probe. RESULTS: Significant difference was identified between the patients with psoriasis and control group, in terms of CPI (Community Periodontal Index), oral hygiene habits, frequency of tooth brushing and flossing (P = 0.01, P = 0.001, P = 0.01, P = 0.05, respectively). A positive correlation between the severities of psoriasis and dental disease was determined, but this difference was not statistically significant (P = 0.204). CONCLUSION: The periodontal disease may affect psoriasis as a chronic infectious focus and probably through proinflammatory cytokines. In order to clarify the exact role of periodontal disease in psoriasis, the issue should be studied in larger series with serum cytokine levels.

RESUMO

AIM: Sexual dysfunction has been found in many disorders that are chronic or disabling. The aim of this study was to evaluate the sexual satisfaction levels, sexual function and their relationship with the mental state in a group of patients being followed-up with a diagnosis of Behçet's disease (BD). METHOD: A total of 50 BD patients and 50 control-group subjects were administered the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS), Golombok Rust Sexual Satisfaction Scale (GRISS) and Arizona Sexual Experiences Scale (ASEX). RESULTS: The ASEX, GRISS total, HDRS and HARS scores were significantly higher in the patient group than the control subjects (P = 0.0001, P = 0.007, P = 0.0001, P = 0.0001 respectively). Sexual dissatisfaction was seen in 40 (80%) of the patient-group and 16 (32%) of the control-group subjects according to the GRISS (P = 0.0001). Female study participants had higher mean scores than the control subjects for the ASEX, GRISS total scores and the GRISS satisfaction, avoidance, vaginismus and orgasm subscale scores (P = 0.0001, P = 0.002, P = 0.02, P = 0.001, P = 0.006, P = 0.03 respectively). Male study participants had different mean scores for the controls regarding the ASEX scores and the GRISS impotence, premature ejaculation, satisfaction and frequency subscale scores (P = 0.01, P = 0.01, P = 0.0001, P = 0.03, P = 0.007 respectively). DISCUSSION: The negative effect of the disorder on the biological and functional status and daily living activities in BD patients also influences the patients' sexual experiences and satisfaction. The negative effects of chronic diseases such as BD should therefore be defined and the disorder evaluated from a wide perspective during the treatment process.

RESUMO

OBJECTIVES: We aimed to compare the effect of remifentanil without muscle relaxant with succinylcholine for intubation in microlaryngoscopy. PATIENTS AND METHODS: Eighty patients were randomly divided into two groups: Group R (n=40) and S (n=40) received remifentanil 4 µg/kg intravenously or 1 µg/kg respectively. Anesthesia was induced with 2 mg/kg propofol in both groups. Intubation was performed after bolus administration of 10 ml saline as a placebo or 1 mg/kg of succinylcholine in Group R and S respectively. Remifentanil infusion was initiated at 0.025 µg/kg in each groups. RESULTS: Intubation conditions were similar in both groups. The mean arterial pressure (MAP) values at post-induction period were significantly lower in the Group S than in the Group R (p = 0.001). The requirement for ephedrine in Group R was found to be significantly lower than Group S (p = 0.023). Recovery times were significantly shorter (p = 0.001) and recovery scores were significantly higher (p = 0.021) in Group R. Time to patient could respond to commands was significantly longer in the Group S (p = 0.001). The surgeon's satisfaction score was significantly higher in Group R (p = 0.001). CONCLUSIONS: It was concluded that remifentanil without muscle relaxants provides similar intubating conditions as that provided by succinylcholine, and remifentanil is superior to succinylcholine with regard to haemodynamic stability and recovery duration.

RESUMO

The aim of the study was to investigate adrenomedullin (ADM) levels and its relation with insulin resistance in women with polycystic ovary syndrome (PCOS). Twenty-nine women with PCOS and 29 age- and body mass index (BMI)- matched control subjects were included in the study. PCOS was defined according to criteria by the Rotterdam European Society of Human Reproduction and Embryology/American Society for Reproductive Medicine (ESHRE/ASRM)-sponsored PCOS consensus workshop group. A full clinical and biochemical examination including basal hormones and metabolic profile was performed. Insulin resistance was calculated by using the homeostasis model assessment of insulin resistance index (HOMA-IR). Plasma ADM levels were measured by high performance liquid chromatographic (HPLC) method. Plasma ADM, fasting insulin levels and HOMA-IR were significantly higher in patients with PCOS than the control group. ADM levels were positively correlated with insulin levels and HOMA-IR index. The best cut-off value of ADM levels to identify the presence of insulin resistance (HOMA-IR≥2.7) was 30.44 ng/ml. Calculated odds ratio of insulin resistance by using logistic regression analysis, as predicted by ADM, was 0.15 (95% confidence interval, 0.037-0.628; p=0.009). In multiple regression analysis, ADM level was an independent predictor of HOMA-IR index. Our finding indicated that ADM levels increased in women with PCOS in accordance with HOMA-IR. ADM could be a significant independent determinant of insulin resistance in women with PCOS.

RESUMO

OBJECTIVES: Effective postoperative pain management after lumbar disc surgery reduces complications and improves postoperative care. The purpose of this prospective, randomized, double-blind, placebo-controlled clinical study is to evaluate the effects of IV paracetamol and ibuprofen on postoperative pain, morphine consumption and side effects of morphine in patients who underwent lumbar disc surgery. MATERIALS AND METHODS: Seventy-five patients aged 18-85 years scheduled for lumbar disk surgery with a single level laminectomy included in this study. All patients received morphine with an IV patient-controlled analgesia device during the first postoperative 24hour. The patients were divided randomly and double-blinded into three groups (control, paracetamol and ibuprofen). The demographic characteristics and procedure data, VAS score, cumulative morphine consumption, opioid-related side effects were recorded. RESULTS: There was no significant difference regarding to demographic characteristics, comorbidities, and durations of anesthesia and surgery. There was a significant difference between all groups regarding to total morphine consumption (P<0.001). IV ibuprofen significantly reduced the total morphine consumption in comparison with control and paracetamol (P<0.001). Repeated measures ANOVA showed in all periods of the study that VAS score was significantly lower in ibuprofen (P<0.001), but not in paracetamol (P=0.394) in comparison with control. There was no difference between groups regarding postoperative heart rate, mean arterial pressure, nausea-vomiting, pruritus and urinary retention. CONCLUSIONS: This study showed that pain scores and morphine consumption, but not the side effects of patient-controlled analgesia during 24hours after the lumbar disk surgery, were significantly reduced by IV ibuprofen as a supplemental analgesic when compared with controls and paracetamols.

RESUMO

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disorder comprising ovulatory dysfunction, hyperandrogenism, and polycystic ovaries (PCO). Several studies have used electrocardiography (ECG) to assess PCOS patients. We aimed to analyze the associations among QRS-T angle, hormonal parameters, and ovarian and thyroid sonography in PCOS. PATIENTS AND METHODS: Adult females with PCOS, but without comorbid illness, were included in our study. Demographic and clinical features (body mass index, Ferriman-Gallwey score, phenotype) were analyzed, as well as laboratory test results. Based on standard 12-lead ECGs, frontal plane QRS-T angles were calculated, defined as the angle between the mean QRS and the mean T vector, and verified with automatic instrument measurements. Values within the range -46 to +59° were classified as "normal", and those out of this range as "abnormal". Patients were divided into groups according to the presence of thyroid nodules, echogenicity (normal/decreased), and vascularity (normal/increased) based on thyroid sonography, and by mean ovarian volume (MOV ≥ 10/< 10 mL) or apparent PCO based on ovarian sonography. RESULTS: The mean age of the 92 patients was 22.68 ± 4.58 years; 11 patients (11.9%) had abnormal QRS-T angles. Demographic, clinical, electrocardiographic, and laboratory parameters were similar between the normal and abnormal QRS-T angle groups, with the exception of MOV, which was higher in the latter group (p=0.032). Among all clinical and laboratory parameters, only MOV was a strong predictor of abnormal QRS-T angle (p=0.016). CONCLUSIONS: Our study is the first to analyze the association between the QRS-T angle and hormonal and sonographic features of patients with PCOS. A small percentage of patients had abnormal QRS-T angles, and a large MOV was a strong predictor of this abnormality.

RESUMO

OBJECTIVE: Hepatic steatosis is a common companion of obesity. Moreover, the measurement of epicardial adipose tissue (EAT) has been reported to be related with both obesity and insulin resistance. Therefore, we aimed to evaluate the relationship between hepatic steatosis, EAT and insulin resistance in obese patients. METHODS: Sixty-three obese subjects were enrolled in the study. Patients were divided into 3 groups according to body mass index (BMI) as follows: 20 patients with 30 < or = BMI < 35 kg/m2 (Group 1, mean age 39.3+/-12.9 yr), 25 patients with 35 < or = BMI < 40 kg/m2 (Group 2, mean age 41.7+/-9.3 yr), and 18 patients with BMI > or = 40 kg/m2 (Group 3, mean age 36.8+/-13.9 yr). EAT and grade of hepatic steatosis were assessed sonographically. Anthropometrical measurements were assessed with the foot-to-foot bioelectrical impedance analysis. Insulin resistance was assessed according to basal insulin, quantitative insulin sensitivity check index (QUICKI) and homeostasis model assessment (HOMA) equations. RESULTS: Although EAT was similarly higher in both groups 2 and 3, these groups were found to be similar in terms of the grade of hepatic steatosis. Both EAT and the grade of hepatic steatosis were correlated with whole body fat mass, abdominal adiposity, insulin resistance, and triglyceridemia but waist circumference was the only factor affecting EAT thickness. Highly sensitive C-reactive protein (hsCRP) was the only metabolic parameter that was significantly higher in Group 3 than in Group 1 (p=0.02). CONCLUSION: Hepatic steatosis should be assessed as a valuable predictor that reflects the increments of whole body fat mass as well as abdominal adiposity. However, in an attempt to demonstrate marginal differences between patients with similar obesity levels, epicardial adipose tissue appears to be a more sensitive marker compared to hepatic steatosis.

RESUMO

Six nosocomial cases of Legionella pneumophila occurred over a two-week period, with one further case being diagnosed retrospectively after 30 days. Strains isolated from the hospital water system were clonally related to a single sputum isolate. A sero-epidemiological investigation into legionella exposure amongst staff and inpatients was undertaken at the eight-year-old Inonu University Medical Centre in Turkey, which has 600 beds and central air conditioning. There is no disinfection programme for the hospital water system. A total of 500 serum samples (400 hospital staff and 100 inpatients) were screened for antibody to L. pneumophila by enzyme-linked immunosorbent assay (ELISA). Seroreactive cases were confirmed by a four-fold antibody rise in ELISA, a high indirect immunofluorescent assay (IFA) antibody titre or a positive urinary antigen test. ELISA showed that 24 (6%) of the 400 hospital staff and seven (7%) of the 100 inpatients had antibody titres higher than the cut-off value. ELISA-seroreactive cases were followed for two to four weeks. Of these subjects, seven (three patients and four staff) showed a four-fold rise in antibody titre by ELISA, six (three patients and three staff) had a high IFA titre, three patients with pneumonia had a positive urinary antigen test, and one of these patients also had a positive sputum culture. In addition, 22 water distribution systems were screened for the presence of L. pneumophila by culture. L. pneumophila was isolated from 15 sites. Pulsed-field gel electrophoresis typing indicated that all strains isolated from water systems were identical and clonally related to the strain isolated from sputum. Superheating and flushing of water systems were undertaken with legionella being re-isolated from four sites. Repeated superheating and flushing eliminated legionella completely. This study demonstrated that rapid detection of L. pneumophila and adequate superheating and flushing of water systems are effective for elimination and reduction of spread of this organism.

RESUMO

The high capacity of liver regeneration after partial hepatectomy (PH) is well known. This study investigated the role of the antioxidant defense system in regeneration among Wistar-albino male rats subjected to 70% partial hepatectomy after a pretreatment period of 2 weeks with eicosapentanoic acid (EPA) rich fish oil (FO), first pressed virgin olive oil (OO), or vitamin E. The control group of 10 rats underwent PH only. On postoperative day 3, all rats were humanely killed. Liver sections of animals treated with FO or vitamin E showed significant increases in regeneration within both liver parenchyma and cut surface compared with the control group (P < .05). Liver sections of OO displayed an insignificant increase in liver regeneration (P > .05), with less increase in parenchyma than of the cut surface. The enhancement of the liver parenchymal regeneration in the FO group was significantly greater than that of the vitamin E group. Concerning liver function tests (LFT), there was no significant difference among the groups. When the treatment groups were compared to the control group glutathione (GSH) levels were increased and content of malondialdehyde (MDA), nitric oxide (NO), and superoxide dismutase (SOD) were decreased. Based on these results, we concluded that after 70% PH in rats, the liver parenchyma and cut surface regeneration were greatest with FO and least with OO treatment. Both FO and vitamin E served to improve the antioxidant defense system more than OO treatment.

RESUMO

Some genetic diseases may increase the cellular instability. Since most human tumors have some genetic base, this study was undertaken for the genetic instability in cancer patients by micronucleus analysis, a mutation-screening test, which is more practical and economic technique than metaphase analysis carried out for chromosomal aberrations. Genetic changes were assessed in untreated cancer patients (lung, stomach and colon cancer) by different genotoxical screening methods; the cytokinesis-block micronucleus test and the buccal mucosa cell micronucleus test. The evaluation of micronuclei number in peripheral blood lymphocytes and buccal cells showed a genomic instability in somatic cells. There was a significant increase in the number of micronuclei in cancer patients prior to the initiation of chemotherapy, and/or radiotherapy compared with healthy human subjects. Furthermore, there was no significant difference between smokers and non-smoking groups or male and female groups. These results suggest that cancer in humans is characterized by an increase of chromosomal damage and thus, the micronucleus assay carried out here may be useful in routine cytogenetic studies of cancer.

RESUMO

The aim of this study was to investigate histological changes in hepatic tissue and effects of pentoxifylline (PTX) and caffeic acid phenethyl ester (CAPE) on these changes using histochemical and biochemical methods in rats, in which hepatitis was established by D-galactosamine (D-GAL). Rats were divided into five groups as follows: control group, D-GAL (24 h) group, D-GAL group, d-GAL + PTX group, and D-GAL + CAPE group. In histological evaluations, the control group showed normal appearance of the liver cells. However in the d-GAL groups, focal areas consisting of inflammatory, necrotic, and apoptotic cells were detected in parenchyma. Glycogen loss was observed in the hepatocytes localized at the periphery of lobule. It was found that number of mast cells of portal areas were significantly higher in D-GAL groups compared with other groups (p = 0.0001). In addition, the number of cells with positive staining by Ki-67 and caspase-3 were significantly increased in GAL groups compared with the control group (p = 0.0001). In biochemical analysis, there was an increase in malondialdehyde and myeloperoxidase levels, while a decrease was observed in glutathione level and glutathione peroxidase activity in groups treated with d-GAL compared with the control group. On the other hand, it was seen that, in the groups treated with D-GAL, histological and biochemical injuries in the liver were reduced by administration of PTX and CAPE. In this study, we demonstrated the ameliorative effects of PTX and CAPE on D-GAL-induced liver injury.

RESUMO

OBJECTIVE: Increased nitric oxide (NO) production in cirrhotic patients causes splanchnic vasodilation, leading to the development of the hyperdynamic circulatory syndrome. One factor that influences plasma NO concentration is eNOS gene polymorphism; consequently, the aim of this study was to investigate whether the eNOS gene G894T and T-786C polymorphisms play any role in the development of ascites in such patients. PATIENTS AND METHODS: Three groups were created: 70 cirrhotic patients with ascites, 69 cirrhotic participants without ascites (stable cirrhosis), and 60 healthy controls. Polymorphisms were determined using polymerase chain reaction (PCR) and melting curve analysis. The plasma nitrite (NO marker) level was measured by deploying the spectrophotometric Griess reaction. RESULTS: Plasma nitrite levels in the cirrhosis with ascites and stable cirrhosis groups were significantly higher than in the controls (p < 0.0001). The frequency of GG, GT, and TT genotypes for the eNOS G894T polymorphism in the cirrhosis with ascites group was 55.7%, 38.6%, and 5.7% respectively, while in the stable cirrhosis group these figures were 60.9%, 36.2%, and 2.9%. In the controls, the distribution was 63.3%, 33.3%, and 3.3%, respectively. The frequency of TT, TC, and CC genotypes for the eNOS-786C polymorphism in the first group was 52.9%, 34.2%, and 12.9% respectively; in the second group, this was 46.4%, 42%, and 11.6%, and in the controls, 48.3%, 46.7%, and 5%. There were no significant differences in genotype and allele distributions of the eNOS-786C and eNOS G894T polymorphisms among the groups. CONCLUSIONS: Plasma nitrite concentration is enhanced in cirrhotic patients, and there is no relationship between the G894T and eNOS-786C polymorphisms and the development of ascites.

RESUMO

The role of oxygen radicals are known for the pathogenesis of kidney damage. The aim of the present study was to investigate the antioxidative effects of melatonin, quercetin, and resveratrol on streptozotocin (STZ)-induced diabetic nephropathy in rats. A total of 35 male Wistar rats were divided into 5 groups as follows: control, diabetes mellitus (DM), DM + melatonin, DM + quercetin, and DM + resveratrol. All the injections started on the same day of single-dose STZ injection and continued for 30 days. At the end of this period, kidneys were removed and processed for routine histological procedures. Biochemical parameters and morphological changes were examined. In DM group, blood glucose levels were significantly increased, whereas body weights were decreased compared with the control group. Significant increases in blood urea nitrogen and tissue malondialdehyde (MDA) levels and decreases in superoxide dismutase and catalase activities were detected in DM group. Administration of melatonin, quercetin, and resveratrol significantly reduced these values. Melatonin was more efficient in reducing MDA levels than other antioxidants (p < 0.05). STZ-induced histopathological alterations including epithelial desquamation, swelling, intracytoplasmic vacuolization, brush border loss and peritubular infiltration. Additionally, basement membrane thickening and sclerotic changes were observed in glomerulus. Transforming growth factor-ß1 positive cells were also increased. Melatonin, quercetin, and resveratrol significantly reduced these histopathological changes. Our results indicate that melatonin, quercetin, and resveratrol might be helpful in reducing diabetes-induced renal damage.

RESUMO

INTRODUCTION: The aim of this study was demonstrate the influence of different positive end-expiratory pressure (PEEP) values on blood flow of the liver by indocyanine green (ICG) clearance test in donor patients. METHODS: ICG clearance tests were conducted concurrently using a noninvasive monitor that tracks the plasma disappearance rate of ICG (PDR-ICG%/min) and 15-minute retention rate after administration of ICG (ICG-R15%). This study was performed in 40 patients who underwent right hepatectomy. RESULTS: The positive end-expiratory pressure (PEEP) was 0 cm H20 in the first (control) group (group K) and 10 mm Hg in the second study group (group P). ICG clearance test values before general anesthesia (T0), after induction of general anesthesia (T1), after transection (T2), 24 hours postoperative (T3), and 72 hours postoperative (T4) were recorded. Simultaneously, hemoglobin (Hgb), hematocrit (Hct), platelet count, plasma levels of prothrombin (PT), International Normalized Ratio (INR), total bilirubin, direct bilirubin, albumin, aspartate aminotransferase, and alanine aminotransferase values were analyzed. In terms of the plasma disappearance rate and retention rate of ICG 15 minutes after administration, significant difference was not observed between groups. PT and INR values were different within comparisons groups (P < .05). There were significant differences in Hgb and Hct values compared with the baseline values (T0) within group (T1, T2, T3, T4) measurements and between group comparisons at T0 and T4 (P < .05). Systemic arterial pressure, mean arterial pressure, and central venous pressure were significantly different between the groups (P < .05). CONCLUSIONS: Given the small magnitude and limited clinical significance of these changes, we conclude that PEEP values between 0 and 10 cm H2O have no effect on global liver function and liver-related liabilities tests in patients undergoing elective liver donor surgery.

RESUMO

BACKGROUND: The number of suitable donors for organ transplantation is limited in many countries. This limitation can be overcome with the use of organs removed from marginal donors (expanded-criteria donors [ECDs]). We examined the long-term results of 187 patients who underwent marginal cadaveric liver transplantation in our institution. METHODS: The data of patients who underwent cadaveric liver transplantation from January 2007 to April 2014 were retrospectively reviewed. ECDs were evaluated by considering 19 internationally accepted criteria. The clinical data of recipients including age, clinical status, and Model for End-Stage Liver Disease (MELD) score were also assessed. RESULTS: A total of 287 patients underwent cadaveric liver transplantation. A graft from an ECD was used in 181 (63.06%) patients. The mean MELD score was 18.8. In all, 45 patients (24.86%) underwent transplantations for fulminant liver failure and 136 patients (75.14%) underwent transplantations for other chronic conditions. The majority of donors died of cerebrovascular disease and trauma. Only hypotension requiring inotropic drugs and obesity significantly affected survival. The 90-day and 12-month survival rates of the recipients who received a graft from an ECD were 51.93% and 46.2%, respectively. CONCLUSIONS: The use of ECD allografts immediately and significantly expands the existing donor pool. Because of persistent organ scarcity, pressure to use a greater proportion of the existing donor pool will continue to increase.

RESUMO

Head circumference (HC) is one of the most significant findings in physical examination, especially in the evaluation of the development and early diagnosis of neurological disorders in children. In the standard charts for developmental evaluation of Turkish children, there is no HC reference values for children over 6 years of age. Since the HC standards show differences among races and generations, many researchers have obtained normal values for their own populations, and recommend periodic reevaluation of these standards. In this study, the HC of 1826 healthy children (945 male, 881 female) aged between 6 and 12 years was measured in order to establish the Turkish standards. The sample represented various socioeconomic levels in the city of Malatya, Turkey. The study was conducted in ten schools and measurements were done twice by a pediatrician and the mean was recorded. Charts and graphs for boys and girls were prepared separately. Results were compared to the values of other populations. HC values of Turkish children were similar to that of Irish children. The data obtained in this study may replace the Nelhaus criteria to be used in clinics. However, a more widespread study should be carried out by including children from different regions of Turkey.

RESUMO

The present study was performed to describe the incidence and risk factors for nosocomial infections (NIs) in the intensive care units of a University hospital. From January to July 2002, 454 patients from Medical and Surgical Intensive Care Unit (MICU and SICU) were observed in the active, targeted, prospective surveillance study. Risk factors for NIs were found by logistic regression analysis. Two hundred and eighteen NIs were recorded in 149 of 454 screened patients. The overall incidence rate was calculated as 33% in the ICUs. The incidence was 39% in MICU and 29% in SICU. The most frequent nosocomial infection observed in MICU, and SICU was pneumonia (42%), and surgical wound infection (31%), respectively. Extrinsic risk factors were urinary catheter, mechanical ventilation, total parenteral nutrition, entubation, antimicrobial treatment prior to the NI, nasogastric cathater and central catheter. The highest intrinsic risk factor was unconsciousness in MICU, respiratory failure in SICU. This high NI rates may be reduced by timely feedback of data for infection control activities. The recognition of risk factors for NIs is an important tool for the identification and development of interventions to minimize such risks in the ICU's.

RESUMO

By the end of 1998, Turkey had launched the routine vaccination of infants against hepatitis B. The purpose of the study is to evaluate the immune response in a sample of vaccinated children aged 1-3 years in the city of Malatya. A total of 210 vaccinated children 12 to 48 months old were selected for the study with 30 cluster sampling in the city of Malatya, Turkey. The children were visited at their homes during January-April 2002. The information on demographic characteristics, family's and child's medical history was gathered, childrens' weight and height were measured and blood samples were taken. Anti-HBs, HbsAg and anti-HBc titers were assayed by micro-ELIZA from the sera. The mean age of the children was 26.3 months, 100 (47.6%) were male and 110 (52.4%) were female. Overall, 203 (96.7%) children had protective anti-HBs levels (> or = 10 IU/l), 0.5% showed evidence of natural infection (with positive anti-HBc and anti-HBs titers), 0.5% had acute or chronic infection (with positive HbsAg and anti-HBc titers) and 2.3% were seronegative. Geometric mean titer of anti-HBs among vaccinated children except those who had positive anti-HBc titers was 138.7 mIU/ml (95% CI:124.7-154.2) and seroconversion rates did not differ by age, sex, anthropometric measurements, time after third dose and place of vaccine administered (P > 0.05). The high seroprotection rate over 95% showed that routine infant vaccination program for hepatitis B was successfully carried out in the city Malatya.
