Traumatic growth and psychological resilience status of female victims of violence inpatients in a district psychiatric hospital

The aim of this study was to examine the traumatic mental growth and psychological resilience status of females who were receiving inpatient treatment at a district mental health hospital and had a history of being subjected to violence. One hundred-twenty female patients with a history of exposure to violence participated in the study. An introductory information form, the Traumatic Growth Inventory (TGI) and the Psychological Resilience Scale for Adults (PRSA) were used for data collection. This study found that all the participants were subjected to emotional violence, 65.8% to physical violence, 30.8% to sexual violence, and 94.2% to verbal violence at some point in their lives. Their TGI mean score (60.96?±?11.91) was above average, while their PRSA mean score (97.90?±?9.18) was below average. The participants' mean scores on the TGI and PRSA did not vary significantly by the type of violence (p?>?0.05) to which the women were exposed. Moreover, no statistically significant relationship was found between the TGI and the PRSA total scale and subscale mean scores (p?>?0.05). This study found that the posttraumatic growth of females who had a history of physical or emotional or sexual abuse was positive, and that their psychological resilience levels were inadequate.     

Serum IL-18 levels in tuberculosis: comparison with pneumonia, lung cancer and healthy controls

OBJECTIVE: The aim of the present study was to document the serum IL-18 levels in patients with pulmonary tuberculosis (P-TB), extrapulmonary tuberculosis (EP-TB), pneumonia, lung cancer and in healthy controls, and to investigate whether it may assist in the differential diagnosis of P-TB. METHODOLOGY: A total of 116 patients were included in the study. The study population consisted of patients with P-TB, EP-TB, pneumonia and lung cancer and controls. P-TB patients were graded according to sputum positivity and extent of disease. Serum levels of IL-18 (ELISA) were compared between groups and with other clinical measures of disease. RESULTS: Compared with the controls, all groups of patients had increased serum levels of IL-18. The highest mean concentration of IL-18 was observed in P-TB. Serum levels of IL-18 in the patients with P-TB correlated well with the extent of disease. CONCLUSIONS: Although increased serum levels of IL-18 were not specific for TB, the increased levels may favour active TB in radiologically advanced disease where CXR findings are difficult to interpret, and sputum smears or cultures are not helpful.     

In case of obesity,longevity-related mechanisms lead to anti-inflammation

The exact mechanisms which contribute to longevity have not been figured out yet. Our aim was to find out a common way for prompting longevity by bringing together the well-known applications such as food restriction, exercise, and probiotic supplementing in an experimental obesity model. Experimental obesity was promoted in a total of 32 young (2 months old) and 32 aged (16 months old) male Wistar albino rats through 8-week cafeteria diet (salami, chocolate, chips, and biscuits). Old and young animals were divided into groups each consisting of eight animals and also divided into four subgroups as obese control, obese food restriction, obese probiotic-fed and obese exercise groups. Probiotic group diet contained 0.05 %w/total diet inactive and lyophilized Lactobacillus casei str. Shirota. The exercise group was subjected to treadmill running 1 h/day, at 21 m/min and at an uphill incline of 15 % for 5 days a week. Food restriction group was formed by giving 40 % less food than the others. The control group was fed regular pellet feed ad libitum. This program was continued for 16 weeks. Blood samples from all the groups were analyzed for fasting glucose, insulin, IGF-1, insulin-like growth factor binding protein 3 (IGFBP-3), interleukin (IL)-6, IL-12, malondialdehyde (MDA), fT3, TT3, fT4, TT4, and liver tissue MDA levels were measured. All applications showed anti-inflammatory effects through the observed changes in the levels of IGFBP-3, IL-6, and IL-12 in the young and old obese rats. While the interventions normally contribute to longevity by recruiting different action mechanisms, anti-inflammatory effect is the only mode of action for all the applications in the obesity model.     

Cell type accuracy of transthoracic fine needle aspiration in primary lung cancer

In this study, we aimed to evaluate the diagnostic accuracy of transthoracic fine needle aspiration (TFNA) specimens in establishing the specific cell type in primary lung cancer and to study the influence of several factors on this accuracy. Forty-six patients with lung cancer diagnosed by TFNA specimens who subsequently underwent thoracotomy between April 2003 and December 2005 were included. Fourty-one patients were men and five were women with a mean age of 59.8 +/- 10 years (34-68 years). TFNA was performed by 22-Gauge Chiba needle with computed tomography guided in all patients. There was cell agreement in 38 of 46 cases (82.6%, Kappa= 0.73). The concordance was 70.8% (Kappa= 0.65) in cases with squamous cell carcinoma and 100% (Kappa= 0.74) in cases with adenocarcinoma (p= 0.01). Stage of the tumor, the diameter and location of the lesion had no effect on cell type agreement (p> 0.05). The concordance was 63.6% in poor differentiated tumors and 92.9% in well differentiated tumors (p> 0.05). Our results pointed out that tumor cell type was the only factor effecting tumor cell type agreement between TFNA and thoracotomy.     

Human regulatory T cells lack the cyclophosphamide‐extruding transporter ABCB1 and are more susceptible to cyclophosphamide‐induced apoptosis

ATP‐binding cassette (ABC) transporters, including ABC‐transporter B1 (ABCB1), extrude drugs, metabolites, and other compounds (such as mitotracker green (MTG)) from cells. Susceptibility of CD4⁺ regulatory T (Treg) cells to the ABCB1‐substrate cyclophosphamide (CPA) has been reported. Here, we characterized ABCB1 expression and function in human CD4⁺ T‐cell subsets. Naïve, central memory, and effector‐memory CD4⁺ T cells, but not Treg cells, effluxed MTG in an ABCB1‐dependent manner. In line with this, ABCB1 mRNA and protein was expressed by nonregulatory CD4⁺ T‐cell subsets, but not Treg cells. In vitro, the ABCB1‐substrate CPA was cytotoxic for Treg cells at a 100‐fold lower dose than for nonregulatory counterparts, and, inversely, verapamil, an inhibitor of ABC transporters, increased CPA‐toxicity in nonregulatory CD4⁺ T cells but not Treg cells. Thus, Treg cells lack expression of ABCB1, rendering them selectively susceptible to CPA. Our findings provide mechanistic support for therapeutic strategies using CPA to boost anti‐tumor immunity by selectively depleting Treg cells.     

Anatomical features of the opening of the nasolacrimal duct and the lacrimal fold (Hasner's valve) for intranasal surgery: A cadaveric study

The location and size of the opening of the nasolacrimal duct and the lacrimal fold (Hasner's valve) are variable. These features have clinical importance in nasal surgery because of the difficulty in determining their location. The aim of this study was to demonstrate the anatomical features of the opening of the nasolacrimal duct and the lacrimal fold and to discuss the importance of such knowledge in minimizing the risk of injury at surgery. Twenty sagittal head sections from formalin‐fixed cadavers were examined. The sections showed no evidence of pathology or trauma. The type of opening of the nasolacrimal duct was a vertical sulcus in 14 of 20 (70%), an oblique sulcus in 2 of 20 (10%), an oblique fissure in 2 of 20 (10%), a vertical fissure in 1 of 20 (5%), and an anteroposterior fissure in 1 of 20 specimens (5%). The lacrimal fold was present in 16 of 20 specimens (80%). Five different forms of this fold were observed. Some morphological features were evaluated quantitatively. We believe that detailed anatomical knowledge of the opening of nasolacrimal duct will be useful in surgical approaches to this area. Clin. Anat. 22:925–931, 2009. © 2009 Wiley‐Liss, Inc.

Trifid mandibular condyle: A case report

A few cases of bifid, but no case of trifid mandibular condyle, have been reported in the literature. This article presents the first reported case of trifid mandibular condyle in a living subject with a history of previous trauma to the temporomandibular joint (TMJ). Additionally, the patient's other condyle was bifid. The patient had no complaint related to the functions of TMJ except for minimal weakness following chewing. The etiology and the prognosis of bifid and trifid condyle are discussed briefly. We considered computed tomography essential to rule out early stages of TMJ pathology in similar cases that resemble trifid mandibular condyle on conventional radiographs.     

Renal cortical thickness and PON1 activity both decrease in chronic renal failure

BACKGROUND: Chronic renal failure (CRF) is associated with a tendency to atherosclerosis due to the enhanced oxidative stress and insufficient antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT) and paraoxonase (PON 1), together with abnormalities in lipid parameters. We determined the in vitro susceptibility of low-density lipoprotein (LDL) to oxidation and PON1 activities in patients with chronic renal insufficiency to see how PON1 affected the progression of the disease and whether hemodialysis influenced these parameters. METHODS: Thirty-seven patients (21 men, 16 women, mean age 43.9 +/- 16) with CRF were included, 23 were receiving hemodialysis treatment. Exclusion criteria were diabetes mellitus and acute coronary disease. Eighteen healthy subjects (9 men and 9 women, mean age 39.9 +/- 10.5) volunteered to participate as controls. All patients were evaluated by renal ultrasound (USG) and two-dimensional echography, and their lipid profiles, PON1 activity, basal and Cu-induced LDL oxidation were determined. RESULTS: PON1 activities of patients were lower than controls (14.4 +/- 11 vs 30.9 +/- 19 U/L, p < 0.05) while basal ox-LDL levels determined by the thiobarbituric acid reactive substances (TBARS) method were higher (0.6 +/- 0.4 vs 0.4+/- 0.2 nmol/mg LDL protein, p<0.01). There was no significant difference between the groups treated with hemodialysis or not. There was a positive correlation between renal cortical thickness and HDL levels (r=0.47, p=0.006) and PON1 activity (r=0.45, p=0.01). CONCLUSION: Our data showed that HDL cholesterol levels and PON1 activities were both lower in patients, indicating depletion of the protective antioxidant capacity. PON1 activities and phenotypes were no different in patients with coronary disease and others so it does not appear to be a significant indicator of coronary artery disease in patients with CRF.     

The effect of preventive use of alanyl-glutamine on diaphragm muscle function in cecal ligation and puncture-induced sepsis model

BACKGROUND: Low muscle glutamine levels during sepsis are associated with reduced protein synthesis and elevated protein breakdown, in particular myofibrillar protein breakdown. Thus, in a cecal ligation and puncture (CLP)-induced sepsis model in the rat, we hypothesized that glutamine pretreatment would protect the diaphragm muscle function. METHODS: Eighty-four male Wistar rats weighing between 180 g and 200 g received standard amino acid solution 1.2 g kg(-1) per day intraperitoneally (IP) or standard amino acid solution 1.2 g kg(-1) per day plus alanyl-glutamine (GLN) 0.25 g kg(-1) per day (IP) during the first 6 days of the experiment. On the seventh day, CLP or sham procedures were applied. The sham and CLP groups were equally divided into 3 subgroups according to the termination of the experiment, which took place at either the 24th hour, 48th hour, or 72nd hour. After the compound muscle action potentials (CMAP) were recorded from the diaphragms of the rats at these selected times, they were decapitated under ketamine/xylazine anesthesia, and diaphragms were harvested for biochemical and histopathological examination. RESULTS: The mean area and amplitude of CMAP were significantly larger in sham+GLN groups when compared with CLP and CLP+GLN groups at all times (p < .05). Diaphragm Ca+2 -ATPase levels were found to be significantly decreased in CLP group at all times compared to sham groups (p < .05). Diaphragm reduced glutathione levels were significantly higher in sham+GLN groups when compared with CLP and CLP+GLN groups at all times (p < .05). In histopathologic assessment, moderate neutrophil infiltration, which was observed in CLP48, was significantly reduced with alanyl-glutamine supplementation in CLP+GLN48 group (p < .05). CONCLUSIONS: This study showed that glutamine pretreatment did not improve diaphragm muscle function, but prevented the biochemical and histopathological changes in diaphragmatic muscle in CLP-induced sepsis. However, further studies are needed to clarify whether a higher dose of glutamine supplementation might protect the diaphragmatic muscle functions.
