Synergistic effect of multiple predisposing risk factors on the development of bezoars

AIM: To describe the clinical characteristics of patients with gastric or intestinal bezoars recently treated in our hospital.METHODS: In this study, a retrospective chart review of consecutive patients with gastrointestinal bezoars, who were treated at the Samsun Education and Research Hospital between January 2006 and March 2011, was conducted. Data on demographic characteristics, clinical presentation, history of risk factors, diagnostic procedures, localization of bezoars, treatment interventions, and postoperative morbidity and mortality rates were collected and evaluated.RESULTS: Forty-two patients [26 (61.9%) males and 16 (31.1%) females] with a mean ± SD (range) age of 55.8 ± 10.5 (37-74) years were enrolled in this study. Thirty-six patients (85.7%) had one or more predisposing risk factors for gastrointestinal bezoars. The most common predisposing risk factor was a history of previous gastric surgery which was identified in 18 patients (42.8%). Twenty three patients (54.8%) had multiple predisposing risk factors. Phytobezoars were identified in all patients except one who had a trichobezoar in the stomach. Non-operative endoscopic fragmentation was performed either initially or after unsuccessful medical treatment in 14 patients with gastric bezoars and was completely successful in 10 patients (71.5%). Surgery was the most frequent treatment method in our study, which was required in 28 patients (66.7%). Intestinal obstruction secondary to bezoars was the most common complication (n = 18, 42.8%) in our study.CONCLUSION: The presence of multiple predisposing factors may create a synergistic effect in the development of bezoars.     

Serum carbohydrate antigen 125 levels in nonischemic dilated cardiomyopathy: a useful biomarker for prognosis and functional mitral regurgitation

The authors investigated the prognostic relevance of serum carbohydrate antigen 125 (CA125) levels in nonischemic dilated cardiomyopathy (NICMP) and assessed whether increased levels relate to the degree of functional mitral regurgitation (FMR). Seventy-seven patients with NICMP were enrolled and followed-up for 10 ± 2 months in this prospective study. Receiver-operating characteristic analysis established a cutoff CA125 value of 25 U/mL for predicting mortality. Patients were divided into two groups according to their CA125 levels (CA125 <25 U/mL [n=58] and CA125 ≥ 25 U/mL [n=19]). Patients with high CA125 values had statistically worse functional status, higher B-type natriuretic peptide (BNP) levels, higher left ventricular volumes, lower ejection fraction, higher E/Em ratio, higher pulmonary artery systolic pressure, and more severe FMR. On the multivariate analysis, serum CA125 (P=.002) and severe FMR (P=.04) were identified as the independent predictors of mortality. Serum CA125 levels also correlated with BNP levels and FMR severity (P<.001). Serum CA125 is a powerful prognostic biomarker that is associated with the severity of heart failure, serum BNP levels and several echocardiographic parameters including left ventricular volumes, systolic and diastolic functions, pulmonary artery pressure, and the degree of FMR. Serum CA125 was also shown as an independent predictor of mortality during 10 ± 2 months of follow-up.     

TLR-4 polymorphisms and leukocyte TLR-4 expression in febrile UTI and renal scarring

Background

In this study, we aimed to determine the relation of TLR-4 Asp299Gly and Thr399Ile polymorphisms and monocyte/neutrophil TLR-4 expression to febrile urinary tract infection (UTI) and renal scar development in children.

Methods

The study was performed in children with a history of febrile UTI. Patients with and without renal scarring were classified as group 1 and group 2, respectively, while the control cases in our previous study were used as the control group (group 3). All three groups were compared for the rate of TLR-4 Asp299Gly and Thr399Ile polymorphisms, and for basal and lipopolysaccharide-stimulated monocyte/neutrophil TLR-4 expression levels.

Results

There were 168 patients (86 in group 1, 82 in group 2) and 120 control cases. Monocyte/neutrophil TLR-4 expression levels were similar in groups 1 and 2. However, both groups had lower TLR-4 expression than group 3. The rate of TLR-4 Asp299Gly polymorphism was not different in all groups. TLR-4 Thr399Ile polymorphism was higher in groups 1 and 2 than in group 3 (14.0, 12.2, and 2.0 %, respectively), while group 1 and group 2 were not different. Furthermore, monocyte TLR-4 expression level was lower in those having TLR-4 Thr399Ile polymorphism than in those without this polymorphism.

Conclusions

Patients with febrile UTI had more frequent TLR-4 Thr399Ile polymorphism and lower monocyte/neutrophil TLR-4 expression. These findings indicate that children carrying TLR-4 Thr399Ile polymorphism and/or having low level of monocyte/neutrophil TLR-4 expression have a tendency to develop febrile UTI. However, we could not show the association of TLR-4 polymorphisms and of TLR-4 expression level to renal scarring.     

A rare inguinal mass: Round ligament leiomyoma

INTRODUCTIONLeiomyoma of the round ligament is a rare condition and usually appears like an inguinal hernia.PRESENTATION OF CASEWe report a case of a 40 year-old women found to have an inguinal mass which it was finally diagnosed as leiomyoma.The patient was admitted to our hospital with a history of painless groin mass. The mass was thought to be irreducible inguinal hernia. Surgical exploration demonstrated a round ligament leiomyoma.DISCUSSIONA smooth muscle tumor in the round ligament of the uterus in the inguinal region is a rare entity and can be mistaken for an irreducible inguinal hernia. It is a rare condition occurring predominantly in premenopausal middle-aged women. Abdominal, inguinal, and vulvar locations have been described. Surgical excision is the curative treatment.CONCLUSIONLeiomyoma of the round ligament should be entertained as a possible etiology of inguinal mass.     

Serum plasminogen activator inhibitor-1 and tumor necrosis factor-α levels in obesity and periodontal disease

Background: Several studies have shown a possible association between periodontal disease and obesity. The aim of this study is to evaluate serum plasminogen activator inhibitor 1 (PAI‐1), tumor necrosis factor‐alpha (TNF‐α), and high‐sensitivity C‐reactive protein (hsCRP) levels in the association between obesity and periodontal disease. Methods: Two hundred individuals participated in this study. Body mass index (BMI), waist‐to‐hip ratio, plasma triglyceride (TRG), total cholesterol, low‐density lipoprotein cholesterol, high‐density lipoprotein cholesterol (HDL‐C), fasting blood glucose (FBG), hsCRP, TNF‐α, PAI‐1, and periodontal parameters (including plaque index [PI], probing depth [PD], clinical attachment level [CAL], and percentage of sites with bleeding on probing) were evaluated. Results: The groups with BMI ≥ 25 had higher median values for FBG, TRG, hsCRP, PAI‐1, PI, and CAL than did the groups with a BMI < 25 (P <0.01). Serum TRG levels were positively correlated with PI, PD, and CAL. There were negative associations between clinical periodontal parameters and HDL‐C. There were statistically significant correlations between PAI‐1 and clinical periodontal parameters (PI, PD, and CAL). Conclusion: Serum PAI‐1 levels may play an important role in the association between periodontal disease and obesity.     

Multiple sulfatase deficiency: A case series of four children

Multiple sulfatase deficiency is biochemically characterized by the accumulation of sulfated lipids and acid mucopolysaccharides. The gene sulfatase-modifying factor 1 (SUMF1), recently identified, encodes the enzyme responsible for post-translational modification of a cysteine residue, which is essential for the activity of sulfatases. We describe clinical findings and mutation analysis of four patients. The patients presented with hypotonia, developmental delay, coarse face, ichthyosis, and hepatosplenomegaly. The diagnosis was made through clinical findings, enzymatic assays, and mutation analysis. We were detected to be homozygous for a novel missense mutation c. 739G > C causing a p.G247R amino acid substitution in the SUMF1 protein.Key Words: Child, multiple sulfatase deficiency, sulfatase-modifying factor 1 gene     

Assessment of atherosclerosis risk due to the homocysteine–asymmetric dimethylarginine–nitric oxide cascade in children taking antiepileptic drugs

PurposeThe aim of this study was to assess the atherogenicity risk of antiepileptics in children by investigating the cascade, “hyperhomocysteinemia (HHcy) → asymmetric dimethylarginine (ADMA) increase → nitric oxide (NO) decrease”, which is thought to contribute to the developmental process of atherosclerosis.MethodsThe participants included 53 epilepsy patients who received either valproic acid (VPA, n = 26) or oxcarbazepine (OXC, n = 27). Twenty-four healthy sex- and age-matched children served as controls. Fasting plasma total homocysteine (tHcy), ADMA and NO levels were measured.ResultsThe differences in Hcy, ADMA, NO, vitamin B₁₂ and folate levels between VPA, OXC and control groups were all insignificant (p > 0.05 for all). In the patient group (VPA and OXC groups), 22.6% of the children (12/53) had tHcy levels above the normal cutoff (13.1 μmol/l) for children and 17% of the children (9/53) had tHcy levels of greater than 15 μmol/l which is accepted as the critical value for an increased atherosclerosis risk (p < 0.05 for both). The difference in rate of HHcy between VPA and OXC groups was statistically insignificant (p > 0.05, for both cut off levels of HHCy). There was a positive correlation of tHcy levels and antiepileptic drug treatment duration in the patient group (r = +0.276, p < 0.05).ConclusionHHcy may develop in patients using OXC. Contrary to some previous publications, our data do not suggest that OXC is safer than VPA in terms of HHcy risk. Further prospective, large scale and longer term studies investigating all suggested pathways responsible for development of atherosclerosis due to HHcy should be conducted to define the exact mechanism responsible for AEDs related atherosclerosis.     

Psychiatric disorders and characteristics of abuse in sexually abused children and adolescents with and without intellectual disabilities

The purpose of this study was to compare sexually abused children and adolescents, with and without intellectual disabilities (ID), in terms of post-abuse psychiatric disorders, features of the sexual abuse, and sociodemographic characteristics. The study included sexually abused children aged 6–16 years, who were sent to three different child mental health units for forensic evaluation; there were 102 cases (69 girls and 33 boys) with ID and 154 cases (126 girls and 28 boys) without ID. Researchers retrospectively examined the files, social examination reports, and the judicial reports of the cases. It was determined that in the group with ID, sexual abuse types including penetration and contact had higher rates, they were exposed to more frequent repeated abuses, the abuses were revealed with their own reports at a later period and lower rates, and post-abuse pregnancies were more frequent. It was also determined that the abuser was a familiar person and a family member at lower rates and more than one abuser was encountered more frequently, compared to the group without ID. While no difference was determined between the two groups in terms of the frequency of post-abuse post-traumatic stress disorder (PTSD) and major depressive disorder (MDD), conduct disorder (CD) was observed more frequently in the group with ID. This study emphasizes that sexual abuse, which is an important problem in individuals with ID, has different features and effects.
