PURPOSE: Although spontaneous intramural hematomas of the gastrointestinal tract are very rare, they may be observed with the use of oral anticoagulant, though less frequently in cases of hematological malignancy and other bleeding disorders. Cases diagnosed as spontaneous intramural hematoma have been assessed in our clinic. METHODS: The cases, which were diagnosed as spontaneous intramural hematoma in the gastrointestinal tract (SIHGT) following anamnesis, physical examination, biochemical, radiological and endoscopic findings from July 2008 to July 2012, have been assessed retrospectively. RESULTS: Seven out of 13 cases were women and the mean age was 65.1 years (34 to 82 years). The most frequent complaint on admission was abdominal pain. The most frequent location of SIHGT was the ileum (n = 8). Oral anticoagulant use was the most common cause of etiology (n = 12). In 10 cases, International normalized ratio values were higher than treatment range (2 to 3, where mechanical valve replacement was 2.5 to 3.5) and mean value was 7.6 (1.70 to 23.13). While 12 cases were discharged without problems with medical treatment, one case with acute myeloid leukemia died in the intensive care unit following cerebrovascular attack. CONCLUSION: Spontaneus bleeding and hematomas that may arise in connection with bleeding diathesis may be fatal in cases with long-term oral anticoagulant treatment and insufficient follow-up. In management of these cases, it may be necessary to arrange conservative follow up and/or initialize low molecular weight heparin, and administer vitamin K as well as replace blood products and coagulation factors when indicated.

BACKGROUND: Pinch-off syndrome (POS) is a rare complication after totally implantable venous access device (TIVAD) implantation. In cancer patients, it is important to prevent this rare complication and to recognize it early if it does occur. We present a case series of POS after TIVAD implantation and the results of a literature search about this complication. METHODS: From July 2006 to December 2015, 924 permanent implantable central venous catheter implantation procedures were performed. The most common indication was vascular access for chemotherapy. RESULTS: POS occurred in 5 patients in our clinic. Two patients experienced POS within 2 weeks, and the other 3 patients were admitted to department of surgery, Istanbul Faculty of Medicine at 6 to 14 months following implantation. The catheters were found to be occluded during medication administration, and all patients complained of serious pain. The transected fragments of the catheters had migrated to the heart. They were successfully removed under angiography with a single-loop snare. CONCLUSION: POS is a serious complication after TIVAD implantation. It is important to be aware of this possibility and to make an early diagnosis in order to prevent complications such as drug extravasation and occlusion events.

Objective: This study aimed to examine the changes in serum nesfatin-1, leptin, orexin-A, and total ghrelin levels of patients diagnosed with drug-naive panic disorder (PD) before and after six weeks of the treatment and to compare the findings with the healthy subjects. Methods: The neuropeptides were measured in venous blood samples taken from 32 patients and 32 healthy subjects. The blood samples of the patients who used paroxetine 20 mg/day plus alprazolam 0.5 mg/day were retaken again after six weeks. Measurements were performed with the Enzyme-Linked Immunosorbent Assay (ELISA) method. Results: Serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were found to be significantly lower than the control group (p<0.001, p<0.001, p<0.001, and p<0.001, respectively). When the serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were compared before and after treatment, significant differences were found in terms of orexin-A and total ghrelin levels (p=0.046, p<0.001, respectively). However, no significant differences were found in terms of nesfatin-1and leptin levels (p=0.205, p=0.988, respectively). Conclusion This study reports that PD, like other anxiety disorders, may affect serum nesfatin-1, leptin, orexin-A, and total ghrelin levels, and there may be a relationship between PD treatment and the levels of these neuropeptides. The variability of this relationship among the neuropeptides examined indicates that various factors other than treatment play a role in this process.

OBJECTIVE: It was aimed to detect acylated ghrelin (AG), unacylated ghrelin (UG) and copeptin levels in patients with suicide attempts and to determine if these biomarkers are risk factors for suicide attempts. METHODS: Serum copeptin, AG and GU levels were screened in 128 patients who were admitted to emergency department with suicide attempts and 59 healthy controls. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were applied simultaneously, and the data were compared statistically. RESULTS: AG, UG and copeptin levels were higher in the patient group compared with the healthy control group. BAI scores of patients were found to be positively correlated with BDI scores. While there was a significant difference (p=0.0064) between psychiatric and non-psychiatric patients with suicide attempts in terms of BAI scores, there were no differences in BDI scores and levels of biomarkers. We found significantly increased BDI and BAI scores and increased levels of AG, UG and copeptin in psychiatric and non-psychiatric patients compared with healthy individuals. The specificities yielded by receiver operating characteristic curve analysis in patients with suicide attempts were as follows: 91.53% for AG, 72.88% for UG and 94.92% for copeptin. CONCLUSION: Serum levels of AG, UG and copeptin increase with increasing anxiety and depression in patients with suicide attempts. Increased levels of AG, UG and copeptin could be considered a risk factor for suicide attempts.

AIMTo examine whether a relationship exists between glutathione S-transferase Mu-1 (GSTM1) gene polymorphism and the susceptibility of sperm and seminal plasma from patients with idiopathic infertility to oxidative stress.

METHODSFifty-two men with idiopathic infertility and 60 healthy fertile men were recruited to this study. GSTM1 gene polymorphism was determined by polymerase chain reaction (PCR) and both the infertile and control individuals were divided into GSTM1 null and GSTM1 positive groups according to their GSTM1 gene structure. We compared reactive oxygen species (ROS) generation, malondialdehyde (MDA), protein carbonyls and glutathione (GSH) concentrations, and glutathione S-transferase (GST) activity in seminal plasma and spermatozoa from infertile patients and controls with respect to GSTM1 genotype.

RESULTSSignificantly higher levels of oxidative stress and damage markers were found in idiopathic infertile men with the GSTM1 null genotype compared with those with the GSTM1 positive genotype. There was no significant difference in genotype distribution for the GSTM1 variant between the idiopathic infertile subjects and fertile subjects. Patients with the GSTM1 null genotype also had lower sperm concentrations than those with GSTM1 positive genotype.

CONCLUSIONOur results suggest that the susceptibility of sperm and seminal plasma to oxidative stress is significantly greater in idiopathic infertile men with the GSTM1 null genotype compared with those possessing the gene. Therefore, in patients with idiopathic infertility, GSTM1 polymorphism might be an important source of variation in susceptibility of spermatozoa to oxidative damage.

Capecitabine is an orally available chemotherapeutic agent that is converted to 5-fluorouracil (5-FU) after absorbtion. Capecitabine and its active metabolite, 5-FU, have cardiotoxic effects with reported instances of acute coronary syndromes caused due to coronary vasospasm. However, these agents exert toxic effects on cardiovascular system and beyond vasospasm provacation. We report a 46-year-old patient diagnosed as acute inferior infarction who is treated with capecitabine for 3 months due to metastatic breast carcinoma, in whom thrombotic coronary occlusion was observed in angiography. This case demonstrates that apart from vasospasm, coronary thrombosis could be observed after capecitabine treatment, with a possible direct effect of this drug.

OBJECTIVES: The purpose is to investigate effect of septoplasty and widened nasal patency on voice quality. METHODS: Fifty patients who undergone septoplasty were included in the study. Thirty-three people who had similar age and distribution were enrolled as control group. Before and 1 and 3 months after surgery, anterior rhinomanometry, voice analysis by Multi-Dimensional Voice Program, and spectrographic analysis were performed to patients. The recordings of /a/ vowel were used to evaluate average fundamental frequency (F0), jitter percent, and shimmer percent. In spectrographic analyses, F3–F4 values for the vowels /i, e, a, o, and u/, nasal formant frequencies of the consonants /m/ and /n/ in the word /mini/, and 4 formant frequencies (F1, F2, F3, and F4) for nasalized /i/ vowel following a nasal consonant /n/ in the word /mini/ were compared. The differences in nasal resonance were evaluated. All patients were asked whether change in their voices after the surgery. Preoperative and postoperative voice parameters and anterior rhinomanometry results were compared separately with the control group as well as in the patient group itself. RESULTS: Preoperative total nasal resistance (TNR) values of patients were higher than the control group (P=0.001). TNR values of patients measured one day before surgery and after surgery in the 1st and 3rd months were different and these differences were significant statistically (P=0.001). There was no significant difference between the voice analysis parameters in preoperative, postoperative 1st, and 3rd months. As a result of their subjective reviews, 12 patients (36%) noted their voices were better than before surgery and 20 patients (61%) noted no change before and after surgery. CONCLUSION: Providing widened nasal cavity has no effect on voice quality.

Endothelin (ET) receptor antagonists have been developed to produce a reduction of ET related effects in various diseases, as well as in animal models of airway inflammation. We aimed to investigate the anti-inflammatory potential of bosentan on a rat model of emphysema. Thirty Wistar male rats were classified as control group (group 1), intratracheally (i.t.) instilled with saline, treated with vehicle solution; elastase group (group 2), i.t. instilled with porcine pancreatic elastase (PPE), treated with vehicle solution; and PPE+bosentan group (group 3), i.t. instilled with PPE, treated with bosentan. The levels of TNF-alpha, IL-1beta, IL-6, and IL-8 in bronchoalveolar lavage fluid (BALF) and lung tissue, cell counts in BALF, and histologic analysis of all groups were evaluated. Neutrophile granulocytes (NG) and alveolar macrophages (AM) were increased more in group 2 than in group 1 (P<0.001, P=0.04, respectively). Compared with group 2, neutrophil granulocyte (NG) and alveolar macrophages (AM) counts were decreased in group 3 (P< 0.001). Histological examination confirmed a diffuse neutrophilic inflammation and irregular alveolar air space enlargement in group 2. Treatment with bosentan partially reduced the enlarged lung volumes. Compared with group 1, the BALF levels of TNF-alpha and IL-6, and the lung tissue levels of IL-1beta, IL-6, and IL-8 were increased in group 2 (P=0.028, P=0.005, P=0.001, P=0.019, P<0.001, respectively). The TNF-alpha and IL-8 levels of BALF (P=0.007, P=0.001, respectively), and the TNF-alpha, IL-1beta, IL-6, and the IL-8 levels of lung tissue (P=0.031, P=0.017, P=0.007, P<0.001) were decreased in group 3 compared to group 2. In conclusion, bosentan decreased the inflammatory response by reducing numbers of inflammatory cells and proinflammatory cytokines.

BACKGROUND AND OBJECTIVES: Knowing the ototoxic potential of the agents used in medical treatments is important for the protection of hearing. Although we have knowledge regarding some effects of dexmedetomidine, which is an anesthetic-sparing drug, its influence over the hearing system has never been studied and is obscure yet. The aim of this study is to determine the effects of intravenous dexmedetomidine application during sevoflurane anesthesia on otoacoustic emissions (OAEs). SUBJECTS AND METHODS: This prospective randomized study was performed on 60 patients (34 male, 26 female, mean age: 30.6±9.2 years) who were scheduled for an elective surgery under general anesthesia and the patients were enrolled and randomly divided into 2 groups. They received dexmedetomidine (Group D) or Saline (Group S) infusion during a standardized Sevoflurane anesthesia. Transient and distortion product OAEs were measured preoperatively and postoperatively (24th hour). OAE results were compared within and between groups. RESULTS: In group D postoperative OAEs were lower than preoperative OAEs and postoperative levels of group S, especially at low frequencies (p<0.05). CONCLUSIONS: Dexmedetomidine infusion affects the micromechanical function of cochlea especially in the low-frequency region. Dexmedetomidine should be carefully used during general anesthesia to avoid its probable harmful effects on cochlear micromechanics.

Objectives: Symptomatic local treatment of vaginal atrophy (VA) in menopausal women includes hormonal and nonhormonal preparations. Some women may be reluctant to use vaginal estradiol preparations because of the concern for developing breast cancer and endometrial hyperplasia. Therefore, it is necessary to compare the therapeutic effectiveness of alternative vaginal drugs, such as promestriene, an estrogen agonist, and sodium hyaluronate (NaH), a nonhormonal, water-based agent. Methods: Ninety-one postmenopausal women diagnosed with symptomatic VA were divided into three groups and treated for 12 weeks; 30 women with vaginal estradiol (VE), 30 women with promestriene, and 31 women with NaH. Composite scoring, vaginal maturation index (VMI), pH, frequency of sexual activity, serum hormone levels, and endometrial thickness were evaluated VA before and after treatment. Results: In the comparison of VA examination findings composite scoring, VMI, and vaginal pH values, three different drugs were found to be effective in the treatment (P < 0.05). The VMI following VE treatment was significantly higher than that after NaH treatment (P = 0.031), whereas the promestriene group had a more positive change than the others in terms of increase in after treatment composite scoring and sexual activity frequency (P = 0.031, P = 0.020). There were no differences between the groups in terms of pre and after treatment serum E2 levels and endometrial thickness. Conclusions Based on these findings, we can conclude that the use of promestriene or NaH can prove to be as effective and well tolerated as vaginal estradiol in the symptomatic treatment of vaginal atrophy.
