Abstract
The aim of this study was to examine the color change of single-shade resin composites, which can be used for all tooth shades. In this study, samples were prepared using resin composites with single-shade (Omnichroma, Vitra Unique) and multishade composite systems (G-aenial A'Chord, Clearfil Majesty ES-2 Premium). The initial color values were measured with a spectrophotometer. Then, samples were kept in wine, coffee, black tea, and distilled water and color measurements were made after days 1, 7, and 30. Color change (ΔE00) and whiteness index (WID) values were statistically analyzed using a one-way analysis of variance (ANOVA) test (α=0.05). Single-shade resin composites showed more color change from wine, coffee, and black tea than multishade resin composites (p<0.001). Single-shade composites have a greater discoloration potential. Single-shade resin composites may show more color change from beverages than multishade resin composites, which may negatively affect clinical success.

Abstract
BACKGROUND We previously postulated that orgasmic sensation may occur through recently discovered genital taste bud-like structures. The interaction between the pudendal nerve and Onuf's nucleus may be important for developing orgasmic information. The study aims to investigate whether ischemic damage to Onuf's nucleus-pudendal network following spinal subarachnoid hemorrhage (SAH) causes taste bud degeneration or not. METHODS The study was conducted on 22 fertile male rabbits who were divided into three groups: control (GI; n=5), SHAM (GII; n=5) and study (GIII; n=12). Isotonic solution, .7cm3, for the SHAM, and .7cm3 homologous blood was injected into spinal subarachnoid spaces at S2 level of the study group. Two weeks later, Onuf's nucleus, pudendal ganglia and the taste bud-like structures of the penile urethra were examined histopathologically. Degenerated neuron densities of Onuf's nucleus, pudendal ganglia and atrophic taste bud-like structures were estimated per mm3 and the results analyzed statistically. RESULTS The mean degenerated neuron densities of taste bud-like structures, Onuf's nucleus and pudendal ganglia were estimated as 2±1/mm3, 5±1/mm3, 6±2/mm3 in GI; 12±4/mm3, 35±9/mm3, 188±31/mm3, in GII and 41±8/mm3, 215±37/mm3, 1321±78/mm3, in GIII. Spinal SAH induced neurodegeneration in Onuf's nucleus, pudendal ganglia and taste bud atrophy was significantly different between GI/GII (p<.005); GII/GIII (p<.0005) and GI/GIII (p<.0001). CONCLUSION Ischemic neuronal degenerations of Onuf's nucleus and pudendal ganglia following spinal SAH lead to genital taste bud-like structure atrophy. This mechanism may be responsible for sexual anhedonia and sterility in cases with spinal cord injury, which has not been documented so far. More studies are needed.

Abstract
Blood and cerebrospinal fluid (CSF) acidosis is the most troubling complication in subarachnoid hemorrhage (SAH) if carotid body (CB) networks are disrupted. However, histopathological examination of the choroid plexus (CP) in acidic CSF has not been evaluated so far. In this study, we aimed to investigate the CP in acidic CSF following SAH. Twenty-eight rabbits were used. Five rabbits were used to analyze CB network (control group; n = 5); seven rabbits were injected 1 mL of saline (Sham group; n = 7); and the rest 16 rabbits were given 1 mL of autologous arterial blood inject into the cisterna magna to create SAH (SAH group; n = 16). Blood and CSF pH values were recorded before/during/after the experimental procedures. Nuclear darkening, cellular shrinkage and pyknosis suggested the presence of apoptosis of epithelial cells of CP. The densities of normal and degenerated epithelial cells of CPs were estimated using stereological methods. The relationship between the pH values and degenerated epithelial cell densities of CPs were statistically compared by Mann-Whitney U-test. The pH values of blood were estimated as 7.359 ± 0.039 in the control group, 7.318 ± 0.062 in the Sham group, 7.23 ± 0.013 in the SAH group. CSF pH values were 7.313 ± 0.028 in the control group, 7.296 ± 0.045 in the Sham group, and 7.224 ± 0.012 in the SAH group. Degenerated epithelial cell density of CP was 25 ± 7 in the control group, 226 ± 64 in the Sham group, and 2115 ± 635 in the SAH group. There was a considerable link between CSF pH values and degenerated epithelial cells of CP (P < 0.0001). This study shows that CB insult causes acidosis of CSF as well as cellular degeneration of CP during SAH. This is the first description of this in the literature.

Abstract
BACKGROUND Cardiac ganglia are rechargeable batteries of the heart. The essential role of cardiac ganglia on cardiac life expectancy has not been examined following brain death. The aim of this study was to determine cardiac ganglia numbers and neuron density following subarachnoid hemorrhage (SAH). METHODS Twenty-five hybrid rabbits were grouped as control (n = 5), sham (n = 5), and SAH (n = 15). The SAH groups' animals were subjected to injections of lethal dose of 2.00 cc autologous blood into their cisterna magna until linear EEG was obtained. The hearts of all animals were extracted following intracardiac formalin injection and examined. Cardiac ganglia and normal/degenerated neuron densities of cardiac neurons were recorded. RESULTS The mean volume of normal neuron density of ganglia was 6.980 ± 830/mm3, and the degenerated neuron density of ganglia was 3 ± 1/mm3 in the control group, 6134 ± 712/mm3; 23 ± 9/mm3 in the sham group, 3456 ± 589; 1161 ± 72/mm3 in the surviving group; and 1734 ± 341/mm3, 4259 ± 865/mm3 in the dead animals in the SAH group. The algebraic results of heart work capacity (Wh) were estimated as 1375 ± 210 Wh in the control group, 1036 ± 225 in the sham group, 800 ± 110 Wh in the surviving group, and < 100 ± 20 in the dead animals in the SAH group. Degenerated cardiac neuron density/Wh correlation is statistically meaningful between the dead in the SAH group versus the SAH-surviving, sham, and control groups (P < .0005). CONCLUSIONS Normal cardiac ganglia numbers and/or cardiac ganglia neuron density may be related to cardiac survival following brain death after subarachnoid hemorrhage.

Abstract
Background Breast cancer keeps its importance as an important health problem in developing countries like Turkey. Therefore, breast cancer screening and early diagnosis are more important for these countries. Although there are debates about breast self- examination, it is still involved in breast cancer screening programs in many countries. Aim This study aimed to determine university students' knowledge and practice of Breast Self-Examination (BSE). Materials and Methods The study universe consisted of all the female students studying at a public university. Sample size of 161 was calculated for a predicted event frequency. The research data were collected using a questionnaire. Results A total of 73.3% of the subjects students had heard about BSE. Only half of these students had obtained additional information about BSE. While half of the students indicated that they did perform BSE, 33.3% reported doing so at regular intervals. The majority of the students were aware of BSE and its purpose. Only about half stated, however, that they practice it. Those who practiced BSE were not knowledgeable about how and when to perform it. Conclusions In developing countries, to have adequate knowledge of BSE of young women and to do BSE, it is important to develop a consciousness of breast health and an awareness of breast cancer at this age.

Abstract
AIM To understand possible mechanisms underlying lacrimal gland degeneration when facial nerve root ischemia induces pterygopalatine ganglion injury and subsequent dry eye in a rabbit model of subarachnoid hemorrhage. MATERIAL AND METHODS Rabbits were divided into four groups: control, sham, moderate subarachnoid hemorrhage, and severe subarachnoid hemorrhage. Autologous blood recovered from the auricular artery was injected into the cisterna magna to induce subarachnoid hemorrhage in the two subarachnoid hemorrhage groups; animals were then monitored for dry eye development over 21 days before removal of their facial nerve roots, pterygopalatine ganglia, and lacrimal glands for immunohistochemical analyses. Neuronal viability in the pterygopalatine ganglia was measured; lacrimal gland vesicles were counted by stereological methods. RESULTS The mean tear-filled vesicle number and lacrimal gland volumes significantly decreased with an increase in facial nerve root injury severity and damaged neuron numbers in the pterygopalatine ganglion. Increase in injury severity most significantly decreased the tear-filled vesicle numbers in the pterygopalatine ganglion. CONCLUSION Subarachnoid hemorrhage degenerates facial nerve parasympathetic branches entering the pterygopalatine ganglion, and neuronal density in this ganglion may be correlated with tear secretion. Our data suggest that pterygopalatine ganglion degeneration following subarachnoid hemorrhage induces dry eye.

Abstract
AIM Cerebral vasospasm after subarachnoid hemorrhage (SAH) may lead to a devastating neurological outcome by inducing cerebral ischemia. However the role of external carotid artery (ECA) vasospasm has been rarely reported in the literature. The aim of this study was to elucidate the effect of ECA vasospasm on cerebral ischemia related neurodegeneration in the cerebral cortex after SAH. MATERIAL AND METHODS This study was performed on 23 rabbits, divided into three groups: control (n=5), sham (n=5), and SAH (n=13). Experimental SAH was performed by injecting 0.75 mL auricular arterial homologous blood into the cisterna magna. After three weeks, the animals were decapitated and the common carotid arteries with their external and internal branches and the brains were examined histopathologically. Vasospasm indexes (VSI) of ECAs and internal carotid arteries (ICAs) and degenerated glial cell numbers of temporal cortices (n/mm3) were estimated stereologically and the results were compared statistically. RESULTS Temporal cortex glial cell density was estimated as 136.950±9.257/mm3 in normal rabbits, 131.324±7.987/mm3 in sham, 112.320±6.112/mm3 in light, and 97.543±5.432/mm3 in severe ECA vasospasm. The mean VSI values of ECA of all groups were 1.95±0.21, 2.15±0.29, 2.95±0.65 and 3.12±0.276, respectively. Statistical differences between the VSI values of ECA and degenerated neuron densities in temporal cortices were significant (p < 0.005). CONCLUSION ECA vasospasm was observed to have a more important predictive role on the serious cerebral ischemia and neuronal degeneration after SAH. The mechanism may be related to ischemia of the parasympathetic ganglia of the lower cranial nerves and dorsal root ganglion.

Abstract
Background and Study Aim Basic neurophysiologic principles of the light reflex are well known. However, the effects of degenerated axon densities of oculomotor nerves (OMNs) secondary to posterior communicating artery (PComA) vasospasm following subarachnoid hemorrhage (SAH) have not been investigated. Our aim was to study this subject.
Methods This study was conducted on 19 rabbits. There was a control group of five animals, a sham group of five animals in which saline was injected into the cisterna magna and a study group of nine animals in which homologous blood was injected into the cisterna magna. Pupillary diameters were measured for 1 week, then the animals were decapitated. The normal and degenerated axon densities of the OMNs were examined by stereological methods. Vasospasm indexes (VSIs) of posterior communicating arteries (PComAs) supplying OMNs were estimated and analyzed statistically.
Results The pupillary diameter was 5.439 ± 368 µm, and the mean axon density of the OMNs was 0.924 ± 324/mm3 in the control group. The pupillary diameter and degenerated axon density of the OMNs in animals of the sham group were 6.980 ± 0.370 µm and 36 ± 8/mm3, respectively. The pupillary diameter was 9.942 ± 653 µm, and degenerated axon density of the OMNs was 265 ± 57/mm3 in animals with SAH. The mean VSI values of PComAs were 0.927 ± 0.224 in the control group, 1.542 ± 0.257 in the sham group, and 2.321 ± 0.324 in the SAH group.
Conclusion We found a linear relationship between the axon density of the OMNs and pupillary diameters. High degenerated neuron density in the OMNs may be responsible for an unresponsive pupillary that has not been mentioned in the literature.

Abstract
Peritoneal carcinomatosis has until recently been considered uniformly fatal; it results in intestinal obstructions, eventually leading progression of disease and death. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have become important options for patients with peritoneal carcinomatosis. Completeness of cytoreduction is a major determinant of survival. Frequently, the porta hepatis and the lesser sac are massively involved by tumor. Encasement of portal triad, lesser omentum, retrohepatic vena cava, duodenum, and stomach is frequently seen. The proximity to major portal structures as well as the retrohepatic vena cava makes this dissection challenging. This is the area where meticulous surgical technique and expertise are necessary to obtain complete removal of tumor. Some specific technical considerations are important to assure that all tumor is safely removed.

Abstract
BACKGROUND Photophobia is defined as a painful psychosomatic discomfort triggered by intense light flow through the pupils to the brain, but the exact mechanism through which photophobia is induced by subarachnoid hemorrhage (SAH) is not well understood. In this study, we aimed to investigate whether there was any relationship between the mydriasis induced by the degeneration of the ciliary ganglion (CG) and photophobia in instances of SAH. MATERIALS AND METHODS Five of a total of 25 rabbits were used as the intact control group; five were used in the sham-operated control group; and the remaining 15 were used as the SAH group, which was created by injecting autologous blood into their cisterna magna. All animals were examined daily for 20days to evaluate their level of photophobia, after which their brains, CGs and superior cervical ganglia (SCGs) were extracted bilaterally. The densities of normal and degenerated neurons in these ganglia were examined by stereological methods. RESULTS In SAH animals with a high photophobia score, the mean pupil diameter and density of degenerated neurons density in the CG were greater than in cases with a low photophobia score (p<0.05). Further analysis revealed that the increase in the density of degenerated neurons in the CG following SAH resulted in the paralysis of the parasympathetic pathway of the pupillary muscles and mydriasis, which facilitates the excessive transfer of light to the brain and photophobia. CONCLUSION Our findings indicate that SAH results in a high density of degenerated neurons in the CG, which induces mydriasis and is an important factor in the onset of photophobia. This phenomenon is likely due to more light energy being transferred through mydriatic pupils to the brain, resulting in vasospasm of the supplying arteries.

Abstract
AIM This was a follow-up study to determine postpartum depression (PPD) and its causes in a population previously evaluated in the first trimester of pregnancy. METHODS The study sample consisted of pregnant women who were evaluated in the first trimester and 360 women who were re-evaluated in the postpartum period. Detailed sociodemographic data were obtained from the women, and depression was assessed with the Edinburgh Postpartum Depression scale (EPDS) and Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM) Axis I Disorders (SCID-I). RESULTS In this follow-up study, the prevalence of PPD was 35% (n = 126). A depressive disorder in the first trimester of pregnancy, previous mental disorder, somatic disorder, exposure to domestic violence during pregnancy, baby's staying in the incubator and not breastfeeding were predictors of PPD. Exposure to violence and a history of previous depression predicted depression both in pregnancy and in the postpartum period. CONCLUSION Depression rates are high in Eastern Turkey. Exposure to violence during pregnancy and the existence of a previous mental disorder were risk factors for perinatal depression in this study. Performing screening tests can identify women at risk of pregnancy-related depression. Prevention programs should be established in areas where the prevalence of depression is high.

MATERIAL AND METHODS This study was conducted on 20 rabbits. Experimental SAH was induced by injecting homologous blood into the cisterna magna. During the experiment, electrocardiography and respiratory rhythms were measured daily. After the experiment, any axonal injury or changes to the arterial nervorums of the vagal nerves were examined. All respiratory irregularities and vagal nerve degenerations were statistically analyzed. RESULTS Normal respiration rate, as measured in the control group, was 30 ± 6 bpm. In the SAH-induced group, respiration rates were initially 20 ± 4 bpm, increasing to 40 ± 9/min approximately ten hours later, with severe tachypneic and apneic variation. In histopathological examinations, axon density of vagal nerves was 28,500 ± 5,500 in both control and sham animals, whereas axon density was 22,250 ± 3,500 in survivors and 16,450 ± 2,750 in dead SAH animals. The severity of axonal degeneration of vagal nerves was greater in the six dead animals than in the survivors. CONCLUSION If vagal nerves are lesioned, the muscles of respiration are paralyzed and respiratory reflexes are disrupted. That the ischemic and mechanical factors created by SAH cause vagal nerve root injury and respiration disorders may be inevitable and fatal.

Abstract
OBJECTIVE Respiratory arrest following brainstem herniation has been attributed to injuries resulting from compression of the respiratory centers. While it is widely perceived that the chemoreceptor network, consisting of the glossopharyngeal nerve and carotid body (GPN-CB), is essential for the modulation of respiration, its contribution to the development of respiratory arrest has not been investigated. Therefore, the aim of this study was to investigate whether injury to the GPN-CB occurs in animals with respiratory arrest caused by experimentally-induced subarachnoid hemorrhage. MATERIALS AND METHODS Eighteen hybrid rabbits were used in this study. Four rabbits (n=4) were used to determine the normal structure of the GPN-CB. The remaining rabbits (n=14) received an autologous blood injection into the cisterna magna to produce a subarachnoid hemorrhage, after which they were observed for 20 days. The number of axons and the neuron density in the glossopharyngeal nerve and carotid body, respectively, were counted by stereological methods. The Mann-Whitney U test was used to analyze the results. RESULTS Six of 14 rabbits died within the first week, likely due to brain swelling and crushing injuries that were observed in the brain stem and related structures. In control rabbits, the average neuronal density of the carotid body was 4250 ±1250/mm(3), while the axonal density in the glossopharyngeal nerve was 18000±5100 mm(2). Conversely, in the dead rabbits, the degenerated neuron density of the carotid body was 2100±500/mm(3), while the degenerated axon density in the glossopharyngeal nerve was 8500±2550 mm(2). In addition, histopathological lesions were more severe in the dead rabbits in terms of their glossopharyngeal nerve and carotid body. CONCLUSION There is an important relationship between neurodegeneration in the GPN-CB and mortality rates following experimentally-induced hemorrhage. This relationship suggests that injury to the GPN-CB network disrupts the breathing reflex and results in respiratory arrest following a subarachnoid hemorrhage (SAH).

Abstract
OBJECTIVE Although atypical antipsychotics are well-tolerated and effective treatment options for schizophrenia, they have metabolic side effects, including weight gain and increased risk of Type II Diabetes Mellitus (DM). Adiponectin, produced exclusively in adipocytes, is the most abundant serum adipokine. Low levels of adiponectin are correlated with DM, insulin resistance and coronary heart disease. Usage of atypical antipsychotics may create a risk of metabolic syndrome. The aim of this study was to evaluate the effects of antipsychotic usage on parameters related to development of metabolic syndrome. MATERIALS AND METHODS A total of 27 patients (n=27) (13 women and 14 men) were recruited from our out-patient psychiatry clinic. All patients had been treated with atypical antipsychotics for at least 3 months and were in remission. Patients were evaluated for levels of HDL (High Density Lipoprotein), LDL (Low Density Lipoprotein), TG (Triglyceride) total cholesterol and fasting blood glucose, body weight, BMI (Body Mass Index), waist circumference and serum adiponectin levels. RESULTS Serum adiponectin levels were significantly lower (p:0.000) and body weights were significantly higher (p:0.003) in the patients who had been using atypical antipsychotics for longer than a year in comparison to patients who had been using atypical antipsychotics for one year or less. CONCLUSION Our findings supported the hypothesis that the length of administration of atypical antipsychotics has an effect on metabolic changes. They also highlight the fact that when investigating metabolic changes generated by atypical antipsychotic effects, the length of time that the patient has been on the atypical antipsychotics should also be considered.

Abstract
BACKGROUND The role of SC before CRS/HIPEC for patients with PMCA is unclear. This study explores the effect of SC prior to CRS/HIPEC on overall survival (OS) in patients with PMCA. METHODS 72 patients with recently diagnosed PMCA who underwent CRS/HIPEC were identified from a prospective database. Thirty patients had SC before CRS/HIPEC (Group 1) and 42 did not (Group 2). Patients who were referred to our center after multiple lines of SC were excluded from this analysis. OS was estimated. RESULTS Median follow-up was 3.2 years. Groups were similar regarding lymph node positivity, postoperative SC and rate of complete cytoreduction. Twenty-four (80%) patients in Group 1 and 21 (50%) in Group 2 had high grade histology (HG) (p = 0.01). OS from CRS/HIPEC at 1, 2, and 3 years was 93, 68, 51% in Group 1 and 82, 64, 60% in Group 2, respectively (p = 0.74). Among HG patients 3-year survival was 36% in the SC group vs. 35% in the group without SC (p = 0.67). The 3-year OS for patients with low grade (LG) tumors was 100% in the SC group vs. 79% in the group with no prior SC (p = 0.26). Among patients with signet ring cell (SRC) histology, 1, 2 and 3-year survival was 94, 67 and 22% in the SC group vs. 43, 14, 14% in the group with no SC, respectively (p = 0.028). There were only 6 patients with LG PMCA who received prior SC. CONCLUSIONS Preoperative SC could improve the prognosis of patients with high-grade PMCA with SRC histology.

Abstract
BACKGROUND This is a natural follow-up study that presents the postpartum results of women who experienced depression during pregnancy. METHODS This study involved 78 women diagnosed with depression in the first trimester of pregnancy. All patients were diagnosed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) in the first trimester and all were referred to a psychiatric center for treatment. Of the 78, 73 were contacted postpartum and reassessed by SCID-I. Treatment anamnesis was evaluated retrospectively. RESULTS The women were divided into two groups at the postpartum evaluation according to anamnesis of psychiatric treatment. Twenty-one of the 73 (28.7%) had received treatment during pregnancy (treated group). Fifty-two women had not been treated (untreated group). In the treated group, no postpartum depression was determined (0%). In the untreated group, 92% (n=48) of women had a depressive disorder postpartum (P<0.01). In addition, scores regarding depression, functionality, and perceived social support were worse postpartum for the untreated group. CONCLUSION Untreated depression during pregnancy is an important predictor of postpartum depression. This natural follow-up study is important because it presents very striking rates of postpartum depression. Referral of patients with depression during pregnancy to psychiatric treatment should be provided and is strongly encouraged.

Abstract
BACKGROUND The choroid plexuses (CPs) are brain structures located in the brain ventricles, involved in the production and reabsorption of cerebrospinal fluid (CSF) components, cerebral immune surveillance, and various endocrine-enzymatic activities and acts as a CSF-blood barrier. This study investigated to determine if there is a link between ischemic CP injury and meningo-cerebral inflammation processes. MATERIAL AND METHODS This study was conducted on 18 rabbits. Four rabbits were used as the baseline group to examine the normal structures. Fourteen of the rabbits were used as the study group by injecting 1.00cc of homologous blood into their cisterna magna. The animals were followed by daily monitoring for ten days and then slaughtered. Apoptotic degeneration of the CP cells was determined and statistical analyses were carried out using normal and apoptotic CP cell numbers. Data analyses were comprised of Mann-Whitney U tests. Differences were considered to be significant if p < 0.005. RESULTS Five animals belonging to the study group died between the 5th and 8th days. Unconsciousness, neck stiffness, convulsion, fever, apnea, cardiac arrhythmia, and breathing disturbances were observed in all of the animals who subsequently died. Intraventricular blood leakage was detected in all the dead and three surviving animals. Choroidal artery spasm, choroidal ependymal cell injury, choroidal cell apoptosis, pia-arachnoid thickening, meningocortical adhesions and blood cell density in the subarachnoid spaces were more severe in the more CP degenerated animals than those of the others. There were significant differences between the apoptotic CP cell density and blood cell density in the subarachnoid spaces (p < 0.005). CONCLUSIONS Subarachnoid hemorrhage (SAH) extending to brain ventricles causes ischemic degeneration of the CP by way of triggered choroidal artery vasospasm. It should be emphasized that the prevention of CP function may be an important part of the protection of the brain in SAH.

Abstract
This paper reports on the use of cinema therapy at a psychiatry clinic for inpatients. The program, "Watching Cinema Group Therapy," was used with over 500 inpatients over the course of one year. We found that using movies for group psychotherapy sessions encouraged the patients to talk about their beliefs, thoughts, and feelings while discussing the characters and stories. We also used the movies as a reward for patients who had developed a therapeutic alliance. It motivated the patients to be active instead of simply remaining in their rooms. As a follow-up to full-length films, it was more useful to show short scenes to patients who had been administered high doses of drugs. Movies can be an important, positive, and productive means of treatment and teaching.

Abstract
OBJECTIVE Puberty and adolescence are important periods about mental health, particularly for women. Relationship between age of menarche, psychiatric complaints during adolescence and family stories of psychiatric disorders are investigated. MATERIALS AND METHODS The study is conducted with 61 patients with schizophrenia, 35 patients with bipolar affective disorder, 40 patients with depressive disorder and 60 healthy control subjects. All subjects were evaluated with SCID-I and questionnaire fit for the aim of the study was fulfilled. RESULTS Bipolar affective disorder had a stronger relationship with menarche, psychiatric problems during adolescence were related with early onset of illness in schizophrenia and bipolar groups. Family story of psychiatric illness was related with psychological problems during puberty in schizophrenia group. CONCLUSION This study underlies the puberty and adolescence period for psychiatric illness. An integrative clinical approach is suggested while examining the psychiatric illness at the basis of engaged roles of hormonal effects of menarche, social effect of puberty psychiatric complaints and genetical and psychosocial burden of family story of illness.

Abstract
OBJECTIVE It remains unclear whether or not the vulnerability of depression in women of reproductive age is related with pregnancy or perinatal period. The aim of the study was to determine the prevalence of depressive disorders and related factors in a large sample of non-perinatal women of reproductive age. METHOD This study involved 589 women of reproductive age. At baseline, sociodemographic data and premenstrual assessment forms were completed, and screening tests for the assessment of the severity of depressive symptoms were administered to all of the participants. Participants who had over scale scores of the cut-off point in the screening instruments were assessed with module A of the Structured Clinical Interview for DSM Disorders (SCID-I) to determine DSM IV Axis I disorders. RESULTS The prevalence of depressive disorders was 32.8%. Depressive disorders had high rates in women who were married at younger ages and who had three or more children. Although the prevalence of depressive disorders was 32.8%, only 10.4% of the women had follow-up and treatment in a psychiatric outpatient clinic. CONCLUSION Low education levels, early maternal age, and having more than three children and higher premenstrual symptom scores were risk factors for depressive disorders in non-perinatal reproductive age.

Abstract
The removal of bilateral olfactory bulbs (OBs) can result in serious behavioral, neurochemical, neuroendocrine, and neuroimmune alterations in depressed patients. However, there is little information on how olfactory bulbectomy (OBX) leads to depression. Habenular nuclei and their connections are important in the regulation of psychomotor and psychosocial behaviors through afferent impulses of the olfactory system. Therefore, we investigated whether OB lesions lead to habenular degeneration. We used a sample of 50 rats (25 female and 25 male) for this study. Of these rats, five male and five female rats were taken as the control group. The remaining 40 rats (20 male and 20 female rats) constituted the study group, and frontal burr holes were performed at the OB level on these rats. OB cauterization was applied to 10 male and 10 female rats (n=10, 10; study group 1), mechanical OBX was applied to five male and five female rats (n=5, 5; study group 2), and no procedure was performed on the remaining 10 rats (n=5, 5). The psychomotor movements; pregnancy rates; and sexual, feeding, maternal, social, and grooming behaviors for both study groups were observed daily for 3 months. Their OBs, olfactory cortices, and habenular complexes were examined using stereological methods. All of the animals in the study groups, especially in the cauterization group, demonstrated anorexia, nutritional disorders, weight loss, psychomotor retardation, sexual aversion, decreased grooming behavior, and reduced social interaction similar to depression symptoms. As compared to the control group, the pregnancy rates, number of offspring per mother rat, and birth weights in the study groups were lower, whereas the number of stillbirths was higher. Gross anatomical examinations revealed that the OBs of all of the animals in the study groups were atrophied. Histopathological examinations detected prominent neuronal loss due to apoptosis in the habenular structures in the study groups. We detected a relationship between a decreased healthy neuronal density of the habenula and depressive symptomatology in rats with OBX. We suggest that olfaction disorders might cause neuropsychiatric disorders by affecting neuronal degeneration in habenular nuclei.

Abstract
OBJECTIVE Psychiatric disorders are important factors which affect the quality of life: employment rates, interpersonal and intrafamilial communications, marriage, child-bearing, parental skills and many other social - cognitive areas in different ways. Psychiatric disorders like schizophrenia, bipolar affective disorder and depressive disorder have a negative impact on women's lives. This study has compared the relationship between these mental illnesses and the liabilities of women's lives. METHODS For the purpose of this study, 61 schizophrenics, 35 bipolar and 40 unipolar female patients and 60 healthy controls from a university hospital of eastern Turkey were evaluated with SCID- I, a family environmental scale and a personal information questionnaire. RESULTS The women with psychiatric disorders had higher rates of unemployment, shorter durations of marriage and lower numbers of parity, as compared to their healthy counterparts, especially after the onset of their illnesses. The schizophrenia and bipolar groups are at risk due to the psychotropic medications which they take during pregnancy. The onset or the exacerbations of illnesses during the postpartum period are also seen more in the schizophrenia and the bipolar groups. However, the patients did not use medicines more than the healthy controls during lactation. The schizophrenia and bipolar groups seem to be failing in using reliable methods of contraception. This data is important due to the traditional and the socio-economical structure of eastern Turkey, which may interrelate with the results. CONCLUSION Women have to play various roles in life and they have various challenges which are related to these roles. The female psychiatric patients should be evaluated in the special perspective of 'being women', along with other clinical parameters. The evaluation of the social, cultural and the economic aspects and the collaborative teams of different clinical disciplines which are related to women's mental health would be beneficial.

Abstract
BACKGROUND Acute hydrocephalus (ventricular enlargement within 72 hours) is a common complication in patients with aneurysmal subarachnoid hemorrhage (SAH). Cerebrospinal fluid (CSF) secretion may be increased in the early phases of SAH, but it has not been proved definitively. We studied the histologic features of choroid plexus (CP) in the early and late phases of SAH. METHODS This study was conducted on 20 rabbits, with 5 rabbits in the control group, 5 rabbits in the sham group, and 10 rabbits in the SAH group. In the SAH group, five of the animals were decapitated after 2 days of cisternal blood injections, and the other five animals were decapitated after 14 days of injections. The CP of lateral ventricles were obtained from coronary sections of brains at the level of the temporal horns of the lateral ventricles. Sections were stained with hematoxylin and eosin and Masson trichrome for SAH-related damage and examined stereologically to discern water-filled vesicles, which were counted. Sections were compared statistically. RESULTS The mean numbers of water vesicles were different after SAH between the early decapitated group (group III) and the late decapitated group (group IV). The mean numbers of water vesicles were 2.80 (± 0.05) in the control group (group I), 2.76 (± 0.02) in the sham group (group II), 14.68 (± 0.06) in the early decapitated group (group III), and 4.78 (± 0.13) in the late decapitated group (group IV). Total number of fluid-filled vesicles of CP was also assessed stereologically; the total numbers were 840 (± 16) in group I, 828 (± 7) in group II, 4404 (± 19) in group III, and 1434 (± 41) in group IV. The numbers of water-filled cisterns were significantly increased in the early phases of SAH (P < 0.05). CONCLUSIONS In SAH with aneurysm rupture, increased CSF secretion seems to be triggered by hemorrhage in the early phase, but it is not possible in the late phase because of CP degeneration. In the early phase of hemorrhage, CSF secretion may be stimulated by the irritant receptor glossopharyngeal and vagal nerve endings, which innervate the healthy CP epithelium and arteries. Our findings may be accepted as being causative. It is likewise possible that CSF blockage per se leads to hydrocephalus, and the morphologic changes are sequelae that occur later in the course of disease. This is the first study to show the water vesicles of CP as a causative factor in the development of acute hydrocephalus after SAH.
