Alexithymia and Parental Bonding in Women with Genitopelvic Pain/Penetration Disorder.

Objective: The role of emotion regulation and alexithymia in the pathophysiology of genitopelvic pain/penetration disorder (GPPPD) is emphasized. Parental bonding is linked to emotion regulation and alexithymia. This study aimed to examine the relationships between parental bonding, alexithymia, and GPPPD. Patients and Methods: Sixty-four patients with GPPPD were enrolled in the study, and 60 controls were matched for demographic features. Toronto Alexithymia Scale (TAS-20) was used to evaluate alexithymia, the Bonding to Parents Scale (BPS) was used to assess parental bonding, and sexual functions were assessed via Golombok-Rust Inventory of Sexual Satisfaction (GRISS). Results: The rate of alexithymic traits was statistically higher in the GPPPD group than in the controls (p = 0.005). Patients with GPPPD obtained higher scores on the maternal care/control (p = 0.003) and maternal overprotection (p = 0.008) compared to controls. Difficulty describing feelings factor of alexithymia (p = 0.012) emerged as a predictor of group membership (GPPPD vs controls). To test whether alexithymia was significantly associated with parental bonding, all subjects were divided into two subgroups, alexithymic and non-alexithymic. When the subgroups were compared in terms of parental attitudes, maternal (p = 0.034) and paternal (p = 0.006) overprotection subscale scores were higher in the alexithymic group than in the non-alexithymic group. Discussion: According to the results, alexithymic traits are characteristic of patients with GPPPD; however, although patients with GPPPD may experience difficulties with perceived parental bonding, this factor does not appear to be a predictor of GPPPD.

Can we use endocan level to determine severity of pancreatitis?

Background and study aims: Endothelial cell specific molecule-1 (ESM-1), also known as endocan, is a soluble proteoglycan secreted by human vascular endothelial cells. In some studies, it has been found that endocan have important effects on cell adhesion, inflammation and angiogenesis. In this study, we aimed to evaluate the endocan level in patients with pancreatitis and the availability of endocan level in determining the severity of the disease. Patients and methods: A total of 42 patients with pancreatitis and 33 healthy individuals were included in the study. The serum endocan levels in patients were evaluated 1st and 3 th days after the symptom's onset. Current scoring systems and the relationship between the severity of the disease and endocan levels were evaluated. Results: The endocan levels of the patients on day 1 are significantly correlated only with the APACHE II score (p=0.039 r=0.319), while the endocan values on day 3 are significantly correlated with the BISAP (bedside index of severity in acute pancreatitis) (p=0.013 r=0.380), APACHE II (Acute Physiology and Chronic Health Evaluation)(p<0.001; r=0.53) and Ranson (p=0.037 r=0.32) scores. The cutoff level of endocan (day 3) was calculated 92.2 pg/ml (83% sensitivity and 50% specificity; p=0.039 area under the curve 0.706) for severe pancreatitis when considering the patients with a score of 8 or higher in the APACHE II scoring system. Conclusion: Serum endocan level can be used as a marker of prognosis in patients with pancreatitis. However, studies involving large populations are needed on this matter.

The efficacy of intermittent pneumatic compression as a substitute for manual lymphatic drainage in complete decongestive therapy in the treatment of breast cancer related lymphedema.

The aim of this study is to evaluate the efficacy of intermittent pneumatic compression (IPC) as a substitute for manual lymphatic drainage (MLD) in complete decongestive therapy (CDT) for treatment of advanced stages of breast cancer-related lymphedema. In this randomized, single-blind, controlled study, 46 patients with breast cancer-related lymphedema were divided into 2 groups. Both MLD with compression bandage (CB) group (n=24) and IPC with CB group (n=22) received treatment 3 days a week for 5 weeks. Home exercise program was also given to all patients. At the end of the 5th week, patients were treated with a daily 23-hour compression garment and home exercise routines. Assessments were taken at baseline, the fifth week, and the third month. Arm circumference was measured at 5 different areas, shoulder range of motion (ROM) was evaluated with a goniometer, pain, and tightness, and heaviness sensations were assessed with visual analog scale. Both groups had similar demographic and clinical characteristics (p<0.05). There were no significant differences between groups and both groups showed significant improvement (p<0.05) in the five measurement levels of the arm circumference at the fifth week and third month. Similarly, shoulder ROM, pain, tightness, and heaviness sensations improved in both groups (p<0.05). Both MLD and IPC as a component of CDT were found successful at 5 weeks and 3 months without superiority to each other.

Efficacy of kinesio taping in early stage breast cancer associated lymphedema: A randomized single blinded study.

This study was designed to evaluate the effectiveness of kinesio taping compared to compression garment in treatment of early stage breast cancer-associated lymphedema (BCAL). Patients between 18-70-years old who had unilateral stage 1 BCAL were randomized into group I kinesio taping (KT) and group II compression garment (CG) for this single blinded study. KT was applied with a lymphatic correction technique in three-four day intervals for four weeks. At the end of the fourth week, patients were suggested to wear CGs. Patients in group II were treated daily for 23-hours in CGs. Education, preventive measures, and exercises were given to both groups. All patients were evaluated before the treatment (T0), immediate post treatment (T1), and three months after treatment (T2). Circumference differences were measured between the extremities with a nonelastic tape at five levels. Additionally, shoulder range of motion (ROM) was measured, and pain, heaviness, and sensation of tightness were evaluated with a visual analog scale (VAS). Thirty-five patients with stage 1 BCAL were included and randomized to the KT (n= 16) and CG (n= 19) groups. Demographic data and baseline clinical characteristics were similar. Both groups had reductions in all levels of arm circumference differences at immediate post-treatment and three months after treatment. Pain, tightness, and heaviness scores significantly decreased for both groups at immediate post-treatment and third month. Patients in the KT group had significantly lower pain sores than patients in the CG group. Results demonstrated that both modalities had similar effects in the treatment of early stage BCAL. For patients with early stage BCAL, KT can be an alternative treatment to CG for patients who have difficulties in obtaining and wearing CGs.

Childhood trauma and dissociation among women with genito-pelvic pain/penetration disorder.

OBJECTIVE: Causes such as childhood trauma, negative attitude about sexuality, inadequate sexual knowledge and education, relationship problems, and unconscious motivation are reported about psychosexual development in the etiology of genito-pelvic pain/penetration disorder (GPP/PD). There are few studies that focus directly on research etiology of GPP/PD and use structured scales. The aim of this study was to research childhood trauma and dissociation forms among women with GPP/PD. PATIENTS AND METHODS: Fifty-five women with GPP/PD according to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders and 61 healthy women with no complaints of sexual function as a control group, in the age range of 18-60 years, were included in this study. Sociodemographic data form, Childhood Trauma Questionnaire (CTQ-28), Dissociative Experiences Scale (DES), and Somatoform Dissociation Questionnaire (SDQ-20) were administered to all participants. RESULTS: Sexual abuse, emotional abuse, and emotional neglect scores, which comprise the subgroups of CTQ, were found high among women with GPP/PD compared with the control group (p=0.003, p=0.006, p=0.001). While a significant difference between the two groups' SDQ scores was obtained (p=0.000), no significant difference was detected between the two groups' DES scores (p=0.392). DISCUSSION: The results evoke the question are genitopelvic pain conditions, vaginismus and dyspareunia, that cannot be explained with a medical cause and that cause penetration disorder, a kind of dissociative symptom prone to develop in some women with childhood psychogenic trauma.

Roles of adiponectin and leptin as diagnostic markers in pancreatic cancer.

NTRODUCTION: Obesity is one of the most serious public health problem worldwide. Adipose tissue synthetize and secrete many growth factors and several cytokines known as adipokines. Studies demonstrated changes in the levels of these adipokines in many types of cancer associated with obesity. In this study, we aimed to evaluate the possible relationship between adiponectin and leptin levels with pancreas cancer and disease stage, representative of Turkish population. MATERIALS AND METHODS: The study was conducted between April 2012 - November 2013. Study included 46 patients - 46 control subjects, who had pancreatic carcinoma. Results between the patients and the control group and relationship between the disease stage and results were evaluated. RESULTS: The comparison of preoperative adiponectin and leptin levels of the study group with the levels of the control group showed that there was no correlation with adiponectin and pancreas cancer. In contrast, leptin levels in the study group were significantly lower than in the control group. There was no correlation between the disease stage and adiponectin and leptin levels. CONCLUSION: There was a significant correlation between low leptin levels and pancreatic cancer, while adiponectin had no correlation. Differential diagnosis of pancreas cancer can be made by evaluating low leptin levels with elevated tumor markers (Tab. 3, Ref. 17).

Behçet Disease serum is immunoreactive to neurofilament medium which share common epitopes to bacterial HSP-65, a putative trigger.

Autoimmune and dysimmune inflammatory mechanisms on a genetically susceptible background are implicated in the etiology of Behçet's Disease (BD). Heat-shock protein-65 (HSP-65) derived from Streptococcus sanguinis was proposed as a triggering factor based on its homology with human HSP-60. However, none of the autoantigens identified so far in sera from BD share common epitopes with bacterial HSP-65 or has a high prevalence. Here, we report that sera from BD patients are immunoreactive against filamentous neuronal processes in the mouse brain, retina and scrotal skin in great majority of patients. By using matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and peptide mass fingerprinting, Western blotting and peptide blocking experiments, we have identified neurofilament medium (NF-M) as the probable antigen for the serologic response observed. Clustal Omega analyses detected significant structural homology between the human NF-M and bacterial HSP-65 corresponding to amino acids 111-126, 213-232 and 304-363 of mycobacterial HSP-65, which were previously identified to induce proliferation of lymphocytes obtained from BD patients. We also found that sera immunoreactive against NF-M cross-reacted with bacterial HSP-65. These findings suggest that NF-M may be involved in autoimmunity in BD due to its molecular mimicry with bacterial HSP-65.

Evaluation of strain values of critical anatomic regions for two different pterygomaxillary approaches in Le Fort I osteotomy: An experimental study.

BACKGROUND: The purpose of this experimental study was to measure stresses both on the pterygoid plates and the skull base following two different pterygomaxillary approaches in Le Fort I osteotomy. MATERIAL AND METHODS: The prepared skull models were randomly divided into 2 groups of 7. In the first group (A), the pterygomaxillary area was left intact. In the second group (B), pterygomaxillary separation was performed with a fine bur. The stresses were measured by using strain gauges. These strain gauges were attached to 6 different anatomical sites. The skull models were mounted on a servo-hydraulic testing unit. Each model was then subjected to a continuous linear tension until a plastic deformation was seen. RESULTS: The statistical analyses showed that there were no significant differences (p>.05) between the 2 groups regarding the strain values. Moreover, no statistical differences (p>.05) were found between the two groups in terms of maximum applied forces. CONCLUSIONS: Considering the clinical conditions, the present study shows that when Le Fort I osteotomy performed without pterygomaxillary separation, there is no significant stress on the skull base during the downfracture. Moreover, it is considered that there is no need for an excessive force applied to perform downfracture in Le Fort osteotomies without pterygomaxillary separation.

Vitamin B12, folate, and homocysteine levels in patients with obsessive-compulsive disorder.

It is known that elevated serum homocysteine, decreased folate, and low vitamin B12 serum levels are associated with poor cognitive function, cognitive decline, and dementia. Current literature shows that some psychiatric disorders, mainly affective and psychotic ones, can be related to the levels of vitamin B12, folate, and homocysteine. These results can be explained by the importance of vitamin B12, folate, and homocysteine in carbon transfer metabolism (methylation), which is required for the production of serotonin as well as for other monoamine neurotransmitters and catecholamines. Earlier studies focused on the relationship between folate deficiency, hyperhomocysteinemia, and depressive disorders. Although depressive and anxiety disorders show a common comorbidity pattern, there are few studies addressing the effect of impaired one-carbon metabolism in anxiety disorders - especially in obsessive-compulsive disorder (OCD). This study aimed to measure the levels of vitamin B12, folate, and homocysteine specifically in order to see if eventual alterations have an etiopathogenetic significance on patients with OCD. Serum vitamin B12, folate, and homocysteine concentrations were measured in 35 patients with OCD and 22 controls. In addition, the Structured Clinical Interview for the Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, Text Revision, Yale-Brown Obsessive Compulsive Scale, Hamilton Rating Scale for Depression, and Hamilton Rating Scale for Anxiety were conducted for each patient. It was found that vitamin B12 levels were decreased and homocysteine levels were increased in some OCD patients. Homocysteine levels were positively correlated with Yale-Brown compulsion and Yale-Brown total scores. In conclusion, findings of this study suggest that some OCD patients might have vitamin B12 deficiency and higher homocysteine levels.

An aquaporin 4 antisense oligonucleotide loaded, brain targeted nanoparticulate system design.

Aquaporins (AQPs), members of the water-channel protein family, are highly expressed in brain tissue especially in astrocytic end-feet. They are important players for water hemostasis during development of cytotoxic as well as vasogenic edema. Increased expression of AQPs is important in pathophysiology of neurological diseases such as neuroinflammation and ischemia. Unfortunately, there are a few pharmacological inhibitors of AQP4 with several side effects limiting their translation as a drug for use in clinical conditions. Another therapeutic approach is using antisense oligonucleotides (ASOs) to block AQP4 activity. These are short, synthetic, modified nucleic acids that bind RNA to modulate its function. However, they cannot pass the blood brain barrier (BBB). To overcome this obstacle we designed a nanoparticulate system made up of chitosan nanoparticles surface modified with PEG and conjugated with monoclonal anti transferrin receptor-1 antibody via streptavidin-biotin binding. The nanocarrier system could be targeted to the transferrin receptor-1 at the brain endothelial capillaries through monoclonal antibodies. It is hypothesized that the nanoparticles could pass the BBB via receptor mediated transcytosis and reach brain parenchyma. Particle size, zeta potential, loading capacity and release profiles of nanoparticles were investigated. It was observed that all types of chitosau (CS) nanoparticles had positive zeta potential values and nanoparticle particle size distribution varied between 100 and 800 nm. The association efficiency of ASOs into the nanoparticles was between 80-97% and the release profiles of the nanoparticles exhibited an initial burst effect followed by a controlled release. The results showed that the designed chitosan based nanocarriers could be a promising carrier system to transport nucleic acid based drugs to brain parenchyma.

Long term outcomes of neuroendocrine carcinomas (high-grade neuroendocrine tumors) of the colon, rectum, and anal canal.

INTRODUCTION AND AIM: Neuroendocrine carcinomas (NEC) of the large intestine are rare and aggressive neoplasms. This study was designed to review the experience at a single institution and analyze the outcomes to improve our understanding of these tumors. METHODS: The patients with NEC (high-grade neuroendocrine tumor) of the colon, rectum, and anal canal were identified from June 1993 to April 2011. Clinical features studied were patient demographics, presenting symptoms, tumor location, tumor stage, treatment status and length of follow-up. RESULTS: Twenty-five patients were identified. Stages of the diseases were I (n=5), II (n=1), III (n=10) and IV (n=9). Locations of the tumors were: colon (36%); rectum (28%) and anal canal (36%). Rectal bleeding (36%) and pain (32%) were the most common symptoms but 16% of patients were asymptomatic. Among the patients with local or locally advanced disease, only five patients had surgery alone. The remainder of the patients underwent chemotherapy with/without radiation. Mean follow-up was 33.7 ± 8.4 months after diagnosis. NEC of the large bowel and anal canal has very distinctive pathologic features and a very poor prognosis. More than one third of the patients with NEC had metastatic disease at the time of diagnosis. When these tumors are in an advanced stage none of the treatment modalities impact on survival. CONCLUSION: The present study showed the poor prognosis of these rare tumors.

Factors affecting morbidity after conversion of laparoscopic colorectal resections.

BACKGROUND: The impact of conversion on postoperative outcomes of laparoscopic colorectal surgery remains controversial. The purpose of this study was to assess whether a conversion results in increased postoperative morbidity and mortality, and to evaluate whether any specific factors affect the outcomes of converted procedures. METHODS: Outcomes of procedures requiring conversion among patients undergoing elective laparoscopic colorectal resection between 1992 and 2011 were compared with those for operations completed laparoscopically. Subset analyses were also performed to evaluate the selective impact of patient-, disease- and treatment-related factors and the timing of conversion during surgery on outcomes. Primary endpoints were postoperative mortality and morbidity. RESULTS: Of 2483 patients undergoing laparoscopic colorectal resection, 270 (10.9 per cent) required conversion to open surgery. The 30-day postoperative mortality rate was comparable after laparoscopically completed and converted procedures (0.4 versus 0 per cent respectively; P = 0.610). Factors significantly associated with morbidity after conversion were smoking, cardiovascular co-morbidity, previous abdominal operations (particularly colectomy or hysterectomy) and adhesions. Overall morbidity was not affected by conversion (27.0 per cent at 30 days in both groups; P > 0.999). However, patients experiencing morbidity tended to have had earlier conversions: median (range) 40 (15-90) min into surgery versus 50 (15-240) min for those who did not develop morbidity (P = 0.006). The risk of reoperation for postoperative morbidity was higher following conversion because of complications (13 versus 2.9 per cent; P = 0.024). CONCLUSION: Conversions of laparoscopic colorectal resection are not associated with increased overall morbidity, regardless of the timing of conversion.

Cell death and survival mechanisms are concomitantly active in the hippocampus of patients with mesial temporal sclerosis.

Mesial temporal lobe epilepsy (MTLE) is often characterized pathologically by severe neuronal loss in the hippocampus. In this study we investigated concomitant appearance of the pro-apoptotic and anti-apoptotic mechanisms in injured neurons in epileptic human hippocampi. Postsurgical hippocampal specimens of randomly selected 25 patients with MTLE were studied with standard immunohistochemical techniques to detect the below markers of cell death pathways: truncated Bid - tBid, mitochondrial translocation of Bax (markers of pro-apoptotic Bcl-2 protein activation) and nuclear translocation of AIF (caspase-independent pro-apoptotic pathway). For cell survival pathways, we investigated the expression of c-IAP1, c-IAP2 and Hsp70 (heat shock protein). Immunopositive cells were counted in different regions of the hippocampus. We also verified IAP (inhibitor of apoptosis) expression with Western blotting. The results were statistically compared with hippocampi from non-epileptic autopsy controls. In patient hippocampi, Bax and tBid immunoreactivity were significantly increased and Bax staining was consistent with mitochondrial translocation. AIF was not translocated to the nucleus. c-IAP1 and c-IAP2 were barely detectable in control hippocampi, whereas their expression was dramatically increased in the patients in all hippocampal subfields. Interestingly, these neurons were also positively co-labeled for tBid and translocated Bax. Hsp70 immunreactivity was significantly increased in all surviving neurons in patient hippocampi whereas degenerating neurons failed to express Hsp70. Our findings are consistent with both pro-apoptotic and anti-apoptotic mechanisms being active within the same hippocampal neurons of patients with MTLE, illustrating an ongoing struggle between cell death and survival mechanisms in neurons under stress.

Self-confidence, gender and academic achievement of undergraduate nursing students.

The aim of this study was to determine the self-confidence levels of nursing students and the factors related to such self-confidence. Data were obtained via a questionnaire for socio-demographic characteristics and a 'Self-Confidence Scale' prepared by the researchers. High self-confidence levels were noted in 78.6% of female students and 92.3% of male students. While 84.5% of second-year students had high self-confidence levels, this rate was 76% in fourth-year students. Female nursing students were significantly less self-confident than male students. Self-confidence should be nurtured in a caring nursing curriculum; however, there is a lack of clarity as to what confidence means, how it is perceived by students and what educators can do to instil self-confidence in nursing students.

A rare cause of mechanical bowel obstruction: mesh migration.

The use of mesh has become the gold standard in hernia operations recently due to advantages such as lower recurrence rates, lower post-surgical pain and earlier return to work. Plug mesh application, first described by Robins and Rutkow [Robbins AW, Rutkow IM (1993) The mesh-plug hernioplasty. Surg Clin North Am 73:501-512], is a popular method of hernia repair. Although rare, there may be complications of surgery using plug mesh. This report presents a case of mechanic bowel obstruction due to mesh migration, 3 years after a left inguinal hernia repair with plug mesh method.
