RESUMO

BACKGROUND: It has been demonstrated that there may be a relationship between liver fibrosis and serum biomarkers. The aim of this study was to investigate pre- and postoral antiviral therapy levels of these biomarkers and their relationship with other fibrotic parameters in hepatitis C virus (HCV) patients. METHODS: The study group comprised HCV patients who were treated with oral antiviral regimens. Prior to, and 8 months after the treatment, serum biomarkers, including transforming growth factor-ß (TGF-ß), chitinase-3-like protein 1 (YKL-40), collagen type IV, matrix metalloproteinases (MMPs) and hyaluronic acid levels, were examined and fibrosis-4 (Fib-4) and aspartate aminotransferase to platelet ratio index (APRI) scores were calculated at the same times. RESULTS: In total, 45 HCV patients (aged between 27 and 86 years) participated. Of these 20 (44.4%) were cirrhotic and 25 (55.6%) were noncirrhotic. The concentrations of YKL-40 (P = 0.01) and TGF-ß (P = 0.032) after treatment were significantly higher than the pretreatment values, whereas hyaluronic acid concentrations decreased after treatment (P = 0.001). Noncirrhotic patients had significantly higher (P = 0.03) YKL-40 levels prior to therapy compared to cirrhotic patients. Median MMP-2 concentrations were higher in men than in women (P = 0.001). Prior to treatment, TGF-ß, YKL-40 and collagen type IV levels were negatively correlated with Fib-4 scores, whereas only TGF-ß and YKL-40 concentrations were negatively correlated with APRI scores. CONCLUSION: YKL-40, TGF ß and hyaluronic acid may be markers for fibrotic change during oral therapy for HCV. In particular, TGF ß concentrations correlated with fibrotic indices. However, these results should be confirmed and validated by further research.

RESUMO

Child marriage, which is seen as both a global public health and social problem, is defined as marriage before the age of 18 years. Gender inequality, migration and wars, economic problems, lack of education, and non-deterrent laws are the main causes of child marriage. Child marriage in our country, and other places where child marriage is still commonplace, is a breach of the widely recognized human rights of the child. Prevention of this breach requires effective and target-oriented counter-measures. At the same time, to achieve sustainable change, problems should be analyzed and solutions should be provided with programmed and multi-layered components. It should not be forgotten that "the child is not a bride, the place for the child is in school and the playground."

RESUMO

OBJECTIVE: Our aim was to determine the prevalence of maternal and neonatal vitamin B12 (vit-B12) and folate deficiencies, a new cutoff value of serum vit-B12 in newborns using vit-B12-related metabolites and also cutoff values of homocysteine (Hcy), propionyl (C3) carnitine, and methyl malonic acid (MMA) in newborns using a vit-B12 cutoff value of 200 pg/mL. METHODS: Healthy pregnant women (without iron deficiency) and 98 healthy, term, singleton babies were included. Blood samples were obtained from women 0-8 h before birth and from cord blood during birth for hemogram and to measure serum vit-B12, folate, and Hcy levels. Maternal and cord blood serum vit-B12 levels were classified as low < 200 pg/mL, marginal 200-300 pg/mL, and normal ≥ 300 pg/mL. Neonatal urine MMA levels were analyzed in mothers with a vit-B12 concentration < 300 pg/mL. C3 carnitine levels of newborns were acquired from extended newborn screening. Receiver operating characteristics curve (ROC) analysis was used for serum vit-B12, urine MMA, C3 carnitine, and Hcy. RESULTS: Of total, 98 pregnant women (28.6 ± 5.5-year-old) and 98 newborn were included. Vit-B12 level was lower than 300 pg/mL in 93% of the pregnant women and 61% of cord blood samples. Folate deficiency was not found in either group. There was statistically significant negative correlation between baby C3 carnitine, cord blood folate (r = -0.265, p = .008) and cord blood vit-B12 (r = -0.220, p = .029). In backward stepwise linear regression analysis, maternal vit-B12 level exerted the most marked effect on cord blood vit-B12 level (adjusted R2 = 0.457). In ROC analysis, the Hcy cutoff value was 4.77 µmol/L (68.4% sensitivity, 58.3% specificity, p = .012) for the detection of vit-B12 deficiency. CONCLUSION: Vit-B12 deficiency remains an important health issue for pregnant women and newborns. Our study revealed a cutoff value for Hcy for the detection of nutritional vit-B12 deficiency that could be used in practice for newborns.

RESUMO

ABSTRACT: In the presence of an unhealed granulation tissue-like wound, a possibility of abuse and neglect along with a foreign body should come to mind. However, it may be difficult to recognize a foreign body in patients with atypical clinical presentations. We demonstrated delayed diagnosis of a rubber band embedded into subcutaneous tissue in a 2½-year-old girl who presented with a circumferential scar with 2 granulation tissue-like wounds on her neck due to a foreign body reaction developed over years. With this rare case presentation, we remind the possibility of abuse/neglect along with foreign bodies in neck lesions of children.

RESUMO

BACKGROUND: Despite primary vaccination, infants under six months run a risk of infection with pertussis. OBJECTIVE: To determine the impact of early postpartum maternal pertussis vaccination on protecting infants from the disease. METHODS: All mothers (n=405) who gave birth to healthy term infants were educated on the cocoon strategy. The mothers who consented were immunized with the tetanus-diphtheria-acellular pertussis vaccine within the first three postpartum days. All infants received their pertussis vaccines according to the national schedule. The anti-pertussis IgG titers of infants of thirty vaccinated mothers were compared with those of thirty unvaccinated mothers. RESULTS: The pertussis antibody levels in the infants of vaccinated mothers were significantly higher than those of unvaccinated mothers at the mean infant age of 5.6 ± 1.2 months. Only 6 infants of vaccinated mothers exhibited pertussis-like symptoms, none of whom had positive pertussis PCR. Seventeen infants of unvaccinated mothers had pertussis-like symptoms, and 4 tested positive for pertussis PCR. CONCLUSION: Our results showed that maternal pertussis vaccination, administered within the first three postpartum days, may protect infants against pertussis in their first ten months.

RESUMO

Hepatitis C virus is one of the leading causes of liver cirrhosis and hepatocellular carcinoma. The tumor-associated calcium signal transducer 2 (Tacstd-2) molecule is thought to be involved in the expression of a number of molecules that facilitate transport of hepatitis C into the cell. The aim of this study was to investigate Tacstd-2 concentrations in hepatitis C patients, with and without cirrhosis, and compare with uninfected controls. Sixty-one hepatitis C patients and twenty-nine control (hepatitis C antibody negative patients with dyspeptic complaints) cases were recruited between 2014 and 2016. Tacstd-2 concentrations in all hepatitis C and control patients were measured and compared. In addition, cirrhotic and non-cirrhotic hepatitis C patients were compared in terms of Tacstd-2 concentration, and comparison was made between patients with high and low concentrations of Tacstd-2. The mean Tacstd-2 concentration of patients with Hepatitis C was 691.2 ± 473.3 ng/U was significantly higher (p = 0.043) than in the healthy control group (524 ± 290.1 ng/U). Although the Tacstd-2 value was higher in cirrhotic than the non-cirrhotic patient group, the difference was not statistically significant (p = 0.78). Liver transferase concentrations were higher in hepatitis C patients with a Tacstd-2 concentration <500 ng/U compared to those with a Tacstd-2 concentration >500 ng/U. In patients with hepatitis C, Tacstd-2 level was detected at higher serum concentrations than healthy individuals. The introduction of hepatitis C virus into the cell can be relatively easy in people with a higher serum concentration of Tacstd-2.

RESUMO

BACKGROUND AND STUDY AIMS: The role of oxidative stress in inflammatory bowel disease is increasingly recognised as an important factor. It is assumed that reduced levels of paraoxonase-1 (PON-1) and arylesterase (ARE) may lead to increased inflammation due to increased oxidative stress. This study aimed to investigate the relationship between ARE and PON-1 levels in ulcerative colitis (UC) patients and the difference in these levels in UC patients in comparison to the control group. PATIENTS AND METHODS: The study population consisted of 66 (73.3%) UC patients and 24 (26.7%) healthy individuals as the control group. The UC patients and the control group were compared in terms of PON-1 and ARE levels as oxidative stress markers. The UC patients were also grouped according to Mayo UC activity scores, and the differences in their PON-1 and ARE levels were assessed. RESULTS: The ARE values were statistically higher in the control group in comparison to the UC patients. Concentrations of PON-1 were not statistically different in the UC and control groups. The ARE value was found to be significantly lower in the UC patients with a haemoglobin level below 10 mg/dl. There was a correlation between the ARE and PON-1 values in the UC patients, but there was no difference between the ARE and PON-1 values, based on the UC patients' Mayo disease severity scores. CONCLUSION: This study found that the ARE values of UC patients were lower than those of healthy subjects. The same results could not be determined for PON-1. The data suggest that the antioxidative capacity of UC patients may be reduced.

RESUMO

Approximately 350-400 million people in the world have Hbs Ag (hepatitis B virus surface antigen) positivity. In the international guidelines, the permanent suppression of replication in chronic hepatitis B virus (HBV) infection therapy is reported as the primary therapeutic goal. Trace elements play a key role in liver diseases. The aim of our study is to determine some trace element concentrations in the liver during HBV treatment periods. The measurement of 11 trace elements (manganese, lead, nickel, chromium, cadmium, iron, copper, zinc, silver, cobalt, and aluminum) was carried out by the method of inductively coupled plasma mass spectrometry in liver biopsy materials (before starting treatment and at the sixth month of the treatment period). There was an increase in zinc and copper concentrations in liver materials at the sixth month of treatment compared to the pre-treatment values (the median zinc value was 48.05 µg/g before treatment and 74.9 µg/g at 6 months after initial treatment, p = 0.035; median copper was 2.82 µg/g before treatment and 5.31 µg/g after 6 months, p = 0.002). General estimations indicated that zinc (p = 0.002), iron (p = 0.0244), copper (p = 0.0003), and aluminum (p = 0.0239) values may be effective in HAI (histological activity index) changes. Only iron levels could be at a very low level effective on the changes caused by fibrosis (p = 0.0002). Liver tissue zinc and copper levels increased in parallel with the improvement of inflammation in antiviral-treated HBV patients. In addition, the levels of zinc and copper in the liver tissue can be useful markers for liver tissue damage detection.

RESUMO

Yetim A, Alikasifoglu M, Bas F, Eliaçik K, Çig G, Erginöz E, Ercan O, Bundak R. Glycemic control and health behaviors in adolescents with type 1 diabetes. Turk J Pediatr 2018; 60: 244-254. The purpose of this study was to determine the health/health risk behaviors of a group of Turkish adolescents with type 1 diabetes (T1D) to determine the prevalence and explore the exact effect of these behaviors on glycemic control (GC). A total of 210 adolescents (age 12-20 years; diabetes duration > 6 months; no additional comorbidities), completed a self-administered questionnaire (including some questions from Health Behavior in School-aged Children study questionnaire). Subjects were divided into two groups based on the hemoglobin A1c (HbA1c) levels, measured in the last 3 months: good GC (HbA1c < 8%) and poor GC (HbAc1≥8%). Chi-square tests and backward stepwise logistic regression analysis were used in statistical analyses. Of the patients, 57 had good GC and 153 had poor GC. The results of the backward stepwise logistic regression analysis indicated that being overweight and frequent electronic media use were risk factors for poor GC, whereas computer use for homework for long period of time (≥2 hours/day) was found to be a protective factor in terms of GC. Screening adolescents in terms of health/health risk behaviors such as frequent electronic media use, and giving adolescents health responsibilities should be an integral part of the follow-up of these patients, and intervention programs that lead to behavioral changes should be developed.

RESUMO

AIM: A recent improvement was made on the law regulating maternity leave in 2011 in Turkey. The leave without pay period was increased, the right to stop working on night shifts was granted, and work hours were improved. It is a known fact that returning to work is a barrier against exclusive and total breastfeeding duration. Legal regulations have crucial importance on the ability of working mothers to breastfeed their infants. The aim of this study was to calculate the effect of the improved law on breastfeeding rates among female physicians. Moreover, the difference in the duration of exclusive breastfeeding and total breastfeeding were evaluated in relation to the new law. MATERIAL AND METHODS: Three of the major hospitals in Istanbul were included in the study. A pilot study was planned and our questionnaire was tried. The actual study included 40 female physicians from each hospital. Mothers who went through antenatal or postnatal complications were excluded from the study. Infants who required intensive care after birth or were never breastfed were similarly excluded. A total of 109 female physician resident mothers' questionnaires were included in the study. RESULTS: The effects of the improvement in the law were statistically significant on the duration of maternity leave and improved working hours after returning to work (OR: 2.74 and OR: 2.52). Exclusive breastfeeding rates and total breastfeeding for more than 12 months significantly increased after the new law (OR: 4.47 and OR: 2.56). CONCLUSIONS: This study showed that legal improvements did reflect on positive outcomes. There is more to be done, especially with condition of the work places and distributing rights equally to women practicing in surgical disciplines as well. If the physicians can breastfeed after they become mothers, their experience may affect their breastfeeding advocacy and the guidance they will provide for their patients.

RESUMO

Multiple endocrine neoplasia (MEN1) is a rare autosomal dominant disorder characterized by primary hyperparathyroidism, enteropancreatic neuroendocrine tumors, and anterior pituitary adenomas. A 16-year-old male presented to the emergency outpatient clinic with tonic convulsions. Physical examination in the postconvulsive period was unremarkable and revealed a muscular, postpubertal adolescent. Biochemical tests at admission were consistent with hyperinsulinemic hypoglycemia and remarkable for elevated levels of liver transaminases and creatine kinase. Work-up for a potential inborn error of metabolism and Doppler ultrasound for congenital portal-hepatic shunt were negative. When the patient was questioned, he reported using the anabolic steroid stanozolol to strengthen his muscles. His enzyme levels normalized after cessation of stanozolol. Hypoglycemia did not recur on diazoxide therapy. Magnetic resonance imaging showed two discrete lesions in the pancreas. Distal pancreatectomy revealed two masses 1.1 and 1.4 cm in diameter: a solid pseudopapillary tumor and an insulinoma. The patient also had asymptomatic primary hyperparathyroidism. DNA sequence analysis of the MEN1 gene in the index patient and his father and brother revealed a previously reported "pW183S" heterozygous mutation. This case further adds to the "pancreatic tumor" phenotype of MEN1 with the presence of a solid pseudopapillary tumor. This case report also confirms the need to meticulously question drug abuse in adolescents presenting to clinics with diagnostic challenges.

RESUMO

AIM: Despite the fact that the frequency of stillbirth is estimated to be about the same as that of early neonatal deaths, stillbirth records and statistics are not kept on a regular basis worldwide and their causes cannot be determined. The aim of our study was to examine the causes and characteristics of stillbirths in Istanbul. MATERIAL AND METHODS: All death certificates of 2011 archived in 8 District Cemetery Directorships, which manage 322 cemeteries within the boundaries of Istanbul Metropolitan Municipality, were examined. Based on the burial licences, weight, gestational weeks, the main cause and causes of death related to stillbirth were analyzed. Cervical insufficieny, placenta abnormalities, preeclampsia, complications of multiple pregnancy, chronic diseases of mothers, conditions including malignancy in mothers were evaluated under the title of "maternal and gestational causes." Intrapartum infections, meconium aspiration, and asphyxia were evaluated under the title of "perinatal causes." RESULTS: A total of 2078 stillbirths and 128 abortus records were found among the death certificates. Nineteen of the abortus records and 109 stillbirths were misidentified. A total of 1988 stillbirth records were examined, of which 68.4% were low-birth-weight babies (<2 500 g). Approximately three quarters of the stillbirths were mild preterm and extremely preterm babies, whereas 10% were at or more than 37 gestastional weeks. The cause of death was not known in 30% of the stillbirths. CONCLUSIONS: The cause of death was not known in a significant portion of stillbirths in Istanbul. Recordings should be made more meticulosuly directed to the cause of death. The cause of stillbirth in term babies is another research subject. Regional and global epidemiologic studies are needed to understand the causes of stillbirths and thus to take necessary precautions.

RESUMO

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a common endocrine problem in adolescents with an increasing prevalence of 30%. Pursuing new biomarkers with high specificity and sensitivity in the diagnosis of PCOS in adolescents is currently an active area of research. We aimed to investigate the diagnostic value of anti-Müllerian hormone (AMH), insulin-like peptide-3 (INSL3), inhibin-A (INH-A), and inhibin-B (INH-B) in adolescents with PCOS and also to determine the association, if any, between these hormones and clinical/laboratory findings related with hyperandrogenism. METHODS: The study group comprised 53 adolescent girls aged between 14.5 and 20 years who were admitted to our outpatient clinic with symptoms of hirsutism and/or irregular menses and diagnosed as having PCOS in accordance with the Rotterdam criteria. Twenty-six healthy peers, eumenorrheic for at least two years and body mass index-matched, constituted the controls. Fasting blood samples for hormones [luteinizing hormone (LH), follicle-stimulating hormone (FSH), dehydroepiandrosterone-sulfate (DHEAS), androstenedione (D4-A), total/free testosterone (T/fT), sex hormone binding globulin (SHBG), AMH, INSL3, INH-A, INH-B] were drawn after an overnight fast. RESULTS: In the PCOS group, 83% of the subjects were oligomenorrheic/amenorrheic and 87% had hirsutism. The LH, LH/FSH ratio, total T, fT, free androgen-index (FAI), DHEAS levels were significantly higher (p=0.005, p=0.042, p=0.047, p<0.001, p=0.007, p=0.014, respectively) and SHBG was significantly lower (p=0.004) in PCOS patients as compared to the controls. Although the INSL-3 and INH-B levels showed no difference between the groups (p>0.05), AMH and INH-A levels were found to be significantly higher in the PCOS group compared to the controls (p<0.001, p<0.001, respectively). In multiple linear regression analysis, WC SDS (p=0.028), logD4-A (p=0.033), logSHBG (p=0.031), and total ovarian volume (p=0.045) had significant effects on AMH levels, and LH (p=0.003) on INH-A levels. In receiver-operating characteristic analysis, the cut-off values for AMH and INH-A were 6.1 ng/mL (sensitivity 81.1%) and 12.8 pg/mL (sensitivity 86.8%), respectively, to diagnose PCOS. When AMH and INH-A were used in combination, the sensitivity (96.2%) increased. CONCLUSION: INSL3 and INH-B were not found to have diagnostic value in adolescents with PCOS. On the other hand, it was shown that INH-A could be used as a new diagnostic biomarker in addition to AMH.

RESUMO

The variable presence of adrenal insufficiency (AI) due to hypocortisolemia (HC) in patients with thalassemia is well established; however, the prevalence of adrenocortical hypofunction (ACH) in the zona glomerulosa and zona reticularis of the adrenal cortex is unknown. To establish the prevalence of ACH, we examined the cortisol response to 1-µg and 250-µg ACTH tests, plasma aldosterone (A)/plasma renin activity (PRA) ratio, and serum dehydroepiandrosterone sulfate (DHEAS) levels in a large cohort of patients with thalassemia, and to investigate the impact of total body iron load (TBIL) on adrenocortical function. The setting used was University hospital and government-based tertiary care center. One hundred twenty-one (52 females) patients with ß-thalassemia major (ß-TM) and 72 healthy peers (38 females) were enrolled. The patients underwent a 250-µg cosyntropin test if their peak cortisol was <500 nmol/L in a 1-µg cosyntropin test. Magnetic resonance imaging (MRI) was performed to assess the MRI-based liver iron content and cardiac MRI T2* iron. The associations between ACH and TBIL were investigated. The patients with thalassemia had lower ACTH, cortisol, DHEAS, and A/PRA values compared with the controls (p < 0.001). Thirty-nine patients (32.2 %) had HC [primary (n = 1), central (n = 36), combined (n = 2)], and 47 (38.8 %) patients had reduced DHEAS levels; 29 (24.0 %) patients had reduced A/PRA ratios. Forty-six (38.0 %) patients had hypofunction in one of the adrenal zones, 26 (21.5 %) had hypofunction in two adrenal zones, and 9 (7.4 %) had hypofunction in all three zones. Patient age and TBIL surrogates were significant independent parameters associated with ACH. Cardiac MRI T2* iron was the only significant parameter that predicted the severity of ACH at a cut-off of 20.6 ms, with 81 % sensitivity and 78 % specificity. Patients with thalassemia have a high prevalence of AI due to HC and zona glomerulosa and zona reticularis hypofunction. TBIL surrogates can predict ACH, but cardiac iron was the only surrogate that was adequately sensitive to predict the severity of ACH.

RESUMO

OBJECTIVES: Factors contributing to arteriopathy in patients with Turner syndrome (TS) remain unclear. We assessed arterial stiffness in young, normotensive patients with TS and correlated arterial stiffness with vascular biomarkers, GH treatment and oestrogen exposure. Sixty-one patients with TS (mean age, 12·6 years; range 6·6-21·3 years) were matched for age and sex with 61 healthy peers. Associations between arterial stiffness and high-sensitivity C-reactive protein (hsCRP), B-type natriuretic peptide (BNP), atrial NP (ANP), plasma aldosterone/plasma renin activity (PRA), IGF1 and IGFBP3 were examined after adjusting for well-established confounders of vascular disease. RESULTS: Carotid intima media thickness standard deviation score (SDS), arterial stiffness index SDS and incremental modulus of elasticity SDS were higher, and distensibility coefficient SDS was lower in patients with TS. The duration of GH treatment and oestrogen exposure was not associated with indices of arterial stiffness. TS patients had higher hsCRP, BNP and ANP. Plasma aldosterone/PRA, IGF1 and IGFBP3 were similar in patients and controls. Multivariable regression analyses (R(2) = 0·200-0·668, P < 0·01) showed that BNP was associated with all indices of arterial stiffness. We found that hsCRP was associated with distensibility coefficient SDS (ß = -0·16, P < 0·01). TS was independently associated with increased arterial stiffness (ß = 0·420-3·424, P < 0·001 for all, R(2) = 0·06-0·31). CONCLUSIONS: Young, normotensive TS patients had increased arterial stiffness than that of healthy peers. BNP, and possibly hsCRP, was independently associated with arterial stiffness in TS. Further research will determine any causal inference of these relationships.

RESUMO

BACKGROUND: Calvarial lesions are often detected incidentally in routine radiology. Most lytic lesions of the skull are benign. Enlarged parietal foramina are benign lesions caused by deficient intramembranous ossification. CASE REPORT: An 11 month-old female patient was admitted with a mass on the right of the back of the head. Physical examination showed a soft 5 cm mass area with no palpable bone in the right occipital. The family history revealed a similar mass in a maternal cousin that resolved over time. Craniography showed lytic lesions, and there were no other pathologies on a complete skeletal X-ray. Computed tomography (CT) showed regular-shaped defects in the bilateral temporal bones, right parietal bone, bilateral frontal bones in the upper-medial orbital wall, and particularly in the occipital bone. The well-defined contours, absence of a soft tissue component, and normal structure and density of the adjacent calvarial bones all pointed to a congenital defect. No change in the lesions was observed during a three-year ultrasound follow-up period. CONCLUSION: To the best of our knowledge, this is the first described case of multiple occipital, parietal, temporal, and frontal foramina in the cranium. A diagnosis of enlarged parietal foramina variant should be considered after ruling out the differential diagnosis in patients with multiple calvarial lesions. CT may provide valuable findings for the differential diagnosis, and sonography may be used for follow-up.
