Treatment, not delivery, of the late preterm and term fetus with supraventricular arrhythmia

OBJECTIVE

While in-utero treatment of sustained fetal supraventricular arrhythmia (SVA) is standard practice in the previable and preterm fetus, data are limited on best practice for late preterm (34 + 0 to 36 + 6 weeks), early term (37 + 0 to 38 + 6 weeks) and term (> 39 weeks) fetuses with SVA. We reviewed the delivery and postnatal outcomes of fetuses at ≥ 35 weeks of gestation undergoing treatment rather than immediate delivery.

METHODS

This was a retrospective case series of fetuses presenting at ≥ 35 weeks of gestation with sustained SVA and treated transplacentally at six institutions between 2012 and 2022. Data were collected on gestational age at presentation and delivery, SVA diagnosis (short ventriculoatrial (VA) tachycardia, long VA tachycardia or atrial flutter), type of antiarrhythmic medication used, interval between treatment and conversion to sinus rhythm and postnatal SVA recurrence.

RESULTS

Overall, 37 fetuses presented at a median gestational age of 35.7 (range, 35.0-39.7) weeks with short VA tachycardia (n = 20), long VA tachycardia (n = 7) or atrial flutter (n = 10). Four (11%) fetuses were hydropic. In-utero treatment led to restoration of sinus rhythm in 35 (95%) fetuses at a median of 2 (range, 1-17) days; this included three of the four fetuses with hydrops. Antiarrhythmic medications included flecainide (n = 11), digoxin (n = 7), sotalol (n = 11) and dual therapy (n = 8). Neonates were liveborn at 36-41 weeks via spontaneous vaginal delivery (23/37 (62%)) or Cesarean delivery (14/37 (38%)). Cesarean delivery was indicated for fetal SVA in two fetuses, atrial ectopy or sinus bradycardia in three fetuses and obstetric reasons in nine fetuses that were in sinus rhythm at the time of delivery. Twenty-one (57%) cases were treated for recurrent SVA after birth.

CONCLUSION

In-utero treatment of the near term and term (≥ 35-week) SVA fetus is highly successful even in the presence of hydrops, with the majority of cases delivered vaginally closer to term, thereby avoiding unnecessary Cesarean section. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

The Association between GNRI variability and mortality in peritoneal dialysis patients

BACKGROUND

The objective of this study is to examine the association between The Geriatric Nutritional Risk Index (GNRI) and overall mortality in this population METHODS: GNRI values were calculated by using the serum albumin levels and body weight and the GNRI variability reflects the changes in GNRI change slopes in the follow-up.

RESULTS

GNRI values showed a decrease from the median baseline GNRI of 106.3 (IQR, 95.0,113.4) to 98.4 (IQR, 91.9,108.9) (p<0.001). The median GNRI variability was 4.7 (IQR, 2.5, 10.3). Both baseline GNRI levels [adjusted odds ratio (OR): 0.96, 95% confidence interval (CI): 0.93, 0.99, P = 0.04] and more profoundly GNRI variability [adjusted OR: 1.23, 95% CI: 1.01, 1.44, P = 0.03] were independently associated with mortality.

CONCLUSION

The monitorization of the changes in GNRI values as a variability index is an easy tool that might improve the predictive accuracy of mortality in PD patients. This article is protected by copyright. All rights reserved.

COVID-19: booster(s) vs. hospitalization and Intensive Care Unit admission

OBJECTIVE

As the pandemic continues, different vaccine protocols have been implemented to maintain the protection of vaccines and to provide protection against new variants. The aim of this study was to assess hospitalized patients' vaccination status and document the efficacy of boosters.

PATIENTS AND METHODS

The patients that were hospitalized due to COVID-19 were enrolled from 28 hospitals in Turkey for five months from September 2021. 5,331 confirmed COVID-19 patients from collaborating centers were randomly enrolled to understand/estimate the distribution of vaccination status in hospitalized patients and to compare the efficacy of vaccination/booster protocols.

RESULTS

2,779 men and 2,552 women of which 2,408 (45.2%) were admitted to Intensive Care Units participated in this study. It was found that the highest risk reduction for all age groups was found in groups that received 4 doses. Four doses of vaccination for every 3.7 people under 50 years of age, for every 5.7 people in the 50-64 age group, and for every 4.3 people over 65 years of age will prevent 1 patient from being admitted to intensive care. Regardless of the type of vaccine, it was found that the risk of ICU hospitalization decreased in those who were vaccinated compared to those who were not vaccinated. Regardless of the type of vaccine, the ICU risk was found to decrease 1.25-fold in those who received 1 or 2 doses of vaccine, 1.18-fold in those who received 3 doses, and 3.26-fold in those who received 4 doses.

CONCLUSIONS

The results suggested that the addition of a fourth dose is more effective in preventing intensive unit care even in disadvantaged groups.

The effect of haemoglobin, albumin, lymphocyte and platelet score on the prognosis in patients with multiple myeloma

INTRODUCTION

In multiple myeloma cases, a variety of prognostic parameters have been identified, which contain the Durie-Salmon classification and the international staging system (ISS) that takes the serum ß2 microglobulin and albumin levels, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to-lymphocyte ratio (MLR). This study investigates the effect of haemoglobin, albumin, lymphocyte and platelet (HALP) score which is a marker of inflammation status and nutrition, at the time of diagnosis for the patients with multiple myeloma on prognosis.

METHODS

A total of 200 multiple myeloma patients with HALP scores calculated from serum haemoglobin, albumin, lymphocyte count and platelet levels at the time of diagnosis were retrospectively examined. The effect of HALP score on overall survival (OS) and progression-free survival and its relationship between the previously evaluated prognostic parameters were investigated.

RESULTS

The optimal cut-off value with the ROC curves for the HALP score was 28.8. The patients were divided into two groups according to the optimal value of the HALP score (low-score group: HALP ≤28.8 [n: 134] and high-score group HALP >28.8 [n: 66]). In the group with the high HALP score, the OS was statistically longer than the low HALP score group (84 months and 53 months; p = 0.0001). In addition, when the effects of NLR, PLR, HALP score and ISS stage on OS were examined by multivariate analysis, all these markers were found to be statistically significant predictors.

CONCLUSIONS

HALP score may be a valuable prognostic marker for patients with multiple myeloma.

Prognostic significance of the metastatic lymph node ratio compared to the TNM classification in stage III gastric cancer

Background

We aimed to evaluate a comparative analysis of the prognostic value of the metastatic lymph node ratio (LNR) and pN (TNM) in stage III gastric cancer.

Patients and Methods

A total of 159 stage III gastric cancer patients with curative gastrectomy were retrospectively analyzed. Cutoff values for LNR were designated according to 25%, 50% and 75% percentiles, 0.07, 0.20 and 0.44 respectively. The LNR was divided into four groups as 0 > LNR1 ≤ 0.07; 0.07 > LNR2 ≤0.20; 0.20 > LNR3 ≤0.44; 0.44 > LNR4 ≤1.

Results

The mean age of the patients was 61.1 ± 11.3 years. Male predominance was apparent (73.6%). The 1-year overall survival and recurrence rates were 73.6% and 33.6%, respectively. The univariate cox regression analysis demonstrated age and LNR were the main variables that affected overall survival (OS) (p < 0.05). Harvested lymph nodes less than 16 did not affect OS (p = 0.255). The results of the multivariate cox regression analysis revealed that only LNR was an independent prognostic factor (P < 0.001), while pN was not (p > 0.05). Similar results, as with overall survival, could not be revealed clearly for disease free survival (DFS).

Conclusions

LNR was an independent significant prognostic factor and superior to pN staging in predicting OS but not for DFS in stage III gastric cancer patients. The high LNR levels in our research were found to be associated with poor survival rates. The percentile system we used to determine cutoff values may be considered as a reliable method. Similarly, LNR also provides a reliable prognostic parameter in future staging systems to help guide treatment algorithm plans.

Causes of Granulomatous Inflammation in Native and Allograft Kidneys: Case Series from A Single Center and A Review of the Literature

OBJECTIVE

Granulomatous interstitial nephritis is a rare finding, and etiology differs by geography. We aimed to investigate the distribution of causes of granuloma/granulomata in the kidney and renal survival of these patients in a tertiary care hospital in Western Turkey.

MATERIAL AND METHOD

Medical records of adults who underwent a kidney biopsy procedure in our institution between January 2000 and June 2019 were reviewed. Pathology reports were searched for biopsies where a granuloma was identified.

RESULTS

Nineteen of 1121 (1.7%) kidney biopsies included granuloma, 17 in native kidneys, and 2 in transplants. The majority of indications for native kidney biopsy was a rise in serum creatinine. Etiologies of granuloma included the following: pauci-immune vasculitis (n=11, 64.7%), tuberculosis (n=2, 11.8%), drug-induced (n=2, 11.8%), tubulointerstitial nephritis/uveitis (TINU) syndrome (n=1, 5.9%), and systemic-lupus erythematosus (n=1, 5.9%). Despite treatment, 6 of 11 (54.5%) patients with vasculitis developed end-stage kidney disease (ESKD) during the median follow-up of 16 months. Both of the patients with tuberculosis, and the patient with TINU syndrome developed ESKD months after the kidney biopsy, despite appropriate therapies. The only case with drug-induced granuloma and both cases with allograft kidney granuloma responded well to glucocorticoids, achieving a complete renal recovery.

CONCLUSION

The majority of our series had granuloma in the kidney secondary to vasculitis and renal outcomes appear considerably unfavorable despite treatment, probably related to the primary diagnosis. Multicenter studies are needed to better determine the etiology and outcome of each granuloma etiology at different geographic locations.

Clinical outcomes and programming strategies of implantable cardioverter defibrillator (ICD) devices during childhood in hypertrophic cardiomyopathy: a UK national cohort study

Background

Sudden cardiac death (SCD) is the most common mode of death in childhood hypertrophic cardiomyopathy (HCM). ICDs have been shown to be effective at terminating malignant ventricular arrhythmias but at the expense of a high incidence of complications. The optimal device and programming strategies to reduce complications in this patient group are unknown.

Purpose

To describe the programming strategies and clinical outcomes of ICD implantation in childhood HCM.

Methods

Anonymised, non-invasive clinical data were collected from a retrospective, longitudinal multi-centre cohort of children (&lt;16 years) with HCM (n=687) and an ICD in-situ from the United Kingdom.

Results

96 patients (61 male (64%), 6 non-sarcomeric (6%)) underwent ICD implantation at a median age 14yr (IQR 11–16, range 3–16) and weight 52.3 kg (IQR 34.8–63.1). Indication for ICD was primary prevention in 72 (75%). 82 (85%) had an endovascular system, 3 (3%) epicardial and 11 (12%) subcutaneous system. 61 patients (74%) were receiving one or more cardioactive medications at implantation [B blockers n=66, 70%, disopyramide n=14, 15%, amiodarone n=7, 7%, calcium channel blocker n=7, 9%, other n=5, 6%]. Programming practices varied: all had VF therapies activated (median 220bpm, IQR 212–230); 70 (73%) had a VT zone programmed (median rate 187 bpm, SD 20.9), of which 26 (27%) had therapies activated. 50 patients (61%) had antitachycardia pacing (ATP) activated. Over a median follow up of 53.6 months (IQR 27.3,108.4), 4 patients (4.2%) died following arrhythmic events despite a functioning device. 25 patients had 53 appropriate therapies (ICD shock n=47, ATP n=8), incidence rate 5.22 (95% CI 3.5–7.8). On univariable analysis, secondary prevention indication for ICD implantation was the only predictor of therapy [16 (64%) vs 8 (11.3%), p value &lt;0.001]. 8 (8.3%) patients had 9 inappropriate therapies (ICD shock n=4, ATP n=5), incidence rate 1.37 (95% CI 0.65–2.8), caused by T wave oversensing (n=2), lead migration (n=1), supraventricular tachycardia (n=1). Device complications were seen in 30 patients (31%), including lead complications (n=16) and infection (n=10). No clinical characteristics predicted time to inappropriate therapy or lead complication.

Conclusions

In a contemporary cohort of children with HCM, the incidence of inappropriate therapies is lower than previously reported, yet complication rates remain higher than reported in adult patients. No clinical, device or programming strategies were associated with inappropriate therapies or lead complications.

P0490IS THE SEVERITY OF GLOMERULAR IGG STAINING IN PATIENT WITH IGA NEPHROPATHY USEFUL FOR PREDICTING POOR RENAL PROGNOSIS? THE DATA FROM TSN-GOLD WORKING GROUP

Background and Aims

In IgA nephropathy (IgAN), which is characterized by mesangial IgA accumulation, there is the formation of circulating autoantibodies against galactose deficient IgA1s (Gd-IgA1). IgG / Gd-IgA1 immunocomplexes accumulate in the glomerular mesangium and play a role in the pathogenesis of IgAN. Recent studies have suggested a relationship between glomerular IgG deposition and the severity of glomerular inflammation. However, detection of the presence and severity of IgG in routine immunofluorescence microscopy (IFM) may fail. This study aims to investigate whether IgG positivity detected by IFM is associated with poor renal prognostic indicators and whether renal prognosis can be predicted according to IgG positivity.

Method

4399 patients who were enrolled between May 2009-June 2019 in database of Turkish Society of Nephrology, Glomerular Diseases Working Group (TSN-GOLD) including 44 centers were evaluated. After exclusion criteria, 994 primary IgAN patients were included in the study. Glomerular IgG negative and positive patients were compared by means of Oxford classification scores, histopathological evaluations, proteinuria, creatinine, albumin, blood pressures. IgG positive patients were divided into subgroups according to the grade of the IFM positivity. The relationship between IgG positivity and poor prognosis criteria were evaluated.

Results

Demographic and biochemical findings of glomerular IgG positive and negative patients at the time of biopsy are shown in Table 1. No difference was found between the groups. There was no difference in the demographic and biochemical findings at the time of biopsy in IgG subgroup analyses (Table 2). There was no difference between the histopathological and Oxford MEST scores of the subgroups. Glomerular IgG positivity was not associated with diastolic blood pressure, systolic blood pressure, urea, uric acid, age, eGFR, albumin, proteinuria (p&gt; 0.05 for all, r= -0.084, r= -0.102, r= -0.006, r=0.062, r= 0.014, r= -0.044, r= -0.061, r= -0.066, r= 0.150, respectively).

Conclusion

Glomerular IgG positivity detected by routine IFM in IgAN is not associated with poor renal prognostic indicators. It is difficult to predict renal prognosis by looking at the severity of IgG positivity at the baseline evaluation.

P0431TRENDS OF PRIMARY GLOMERULAR DISEASE IN TURKEY FROM 2009 TO 2017: A REGIONAL REGISTRY REPORT FROM TSN-GOLD WORKING GROUP

Background and Aims

Several glomerular disease registries in Europe, and they shared their data; however, there was a lack of current data on trends of primary glomerulopathy in Turkey. Glomerular disease patterns can change geographical areas and populations decade by decade. Our aim is to present Turkey's primary glomerular disease pattern from 2009 to 2017.

Method

3878 native kidney biopsy records were assessed in the Turkish Society of Nephrology Glomerulopathy (TSN-GOLD) Working Group Registry. Secondary disease (lupus, etc.) and transplant biopsies do not enroll in the registry. These records divided into four periods, before 2009, 2009 to 2013, 2013 to 2017, and 2017 to current.

Results

A total of 3858 patients (M = 2173, K = 1685) were examined. There was no difference in the distribution of number of patients according to periods (Q1 = 968, Q2 = 960, Q3 = 968, Q4 = 962). Nephrotic syndrome was the most common biopsy indication in all quarters (58.6%, 53%, 44.1%, 51.6%, respectively). Glomerulopathy types; Membranous GN (29.9%, n = 290) was the first in Q1 and IgA nephropathy (17.7%, n = 172) was the second. IgA nephropathy (28.5%, n = 274) was the most common glomerulopathy in Q2, while Membranous GN (25.5%, n = 245) was the second most common. IgA nephropathy (29.9%, n = 285) was the most common glomerulopathy in Q3, followed by FSGS (22.9%, n = 222) and Membranous GN. In Q4, FSGS (26.8, n = 258) was the most common glomerulopathy, followed by IgA nephropathy (26.7%, n = 257) and Membranous GN (24.5%, n = 236) (Figure 1).

Conclusion

While biopsy indications did not change over the years, the incidence of FSGS and IgA nephropathy gradually increased.

Is the platelet-to-lymphocyte ratio a new prognostic marker in multiple myeloma?

BACKGROUND

Recent reports showed neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), as a predictor of progression-free survival (PFS) and overall survival (OS) in various malignancies.

MATERIALS AND METHODS

We retrospectively examined the PLR, NLR, and MLR in a cohort of 186 newly diagnosed multiple myeloma (MM) patients. This study investigated the prognostic relevance of NLR, PLR, and MLR in MM patients. NLR, PLR, and MLR were calculated from whole blood counts before therapy. The Kaplan-Meier curves and multivariate Cox models were used for the evaluation of survival.

RESULTS

Applying cutoff of 1.9 (NLR), 120.00 (PLR), and 0.27 (MLR), decreased PLR showed a negative impact on the outcome. Decreased PLR is an independent predictor for PFS and OS. There were no significant differences in median survival between the high and low NLR (P = 0.80) and MLR (P = 0.87) groups.

CONCLUSIONS

In this study, thrombocytopenia and low PLR are associated with poor survival in MM patients does this P value apply to thrombocytopenia or low PLR and may serve as the cost-effective prognostic biomarker.

l-Arginine metabolism before and after 10 weeks of antipsychotic treatment in first-episode psychotic patients

Agmatine is an endogenous NMDA (N-methyl-d-aspartate) antagonist which is synthesized from l-Arginine and described as a novel neurotransmitter. Agmatine is considered to play an important role for the development of schizophrenia. The aim of the present study is to explore the role of agmatine and l-arginine metabolism in medication-naive first-episode psychosis (FEP). We conducted a case control study in medication-naive patients with FEP (n = 40). The healthy volunteers with no family history of schizophrenia (n = 35) matched for age, gender and education level were selected as a control group. The patients were recruited to the study and followed up for 10 weeks. The plasma l-arginine, l-citrulline, l-ornithine and agmatine levels were measured using modified liquid chromatography/mass spectrometry. The plasma levels of l-arginine, l-citrulline and agmatine (p < 0.0001), but not l-ornithine and agmatinase (p > 0.05), were significantly increased during baseline analysis. After 10 weeks of treatment, plasma l-arginine and l-citrulline levels were still significantly increased (p < 0.05) while l-ornithine and agmatinase levels remained unchanged (p > 0.05). Conversely, plasma agmatine levels were significantly decreased after the treatment (p < 0.0001). Positive and negative predictive values of agmatine used for evaluating the diagnostic accuracy were 95.1% and 97.1%, respectively (p < 000.1). This is the first study of arginine metabolism and agmatine in medication-naive first-episode patients and provides evidence of increased levels of an endogenous NMDA antagonist which decreases following antipsychotic treatment.

TARC: Turkish aripiprazole consensus report- Aripiprazole use and switching from other antipsychotics to aripiprazole- consensus recommendations by a Turkish multidisciplinary panel

In this review, we have attempted to share our 10 years' clinical experience with aripiprazole use and switching from other antipsychotics to aripiprazole. There are various reasons for switching, including a partial or complete lack of efficacy, adverse side effects, and partial or noncompliance with medication. Aripiprazole has some unique receptor-binding qualities that provides some advantages over other antipsychotics in certain clinical situations. We have covered potential clinical scenarios for aripiprazole use as a single agent and switching from other agents in inpatient and outpatient settings. Patients switched from other antipsychotics to aripiprazole have been shown to benefit from significant improvements in clinical response and tolerability. This review examines the strategies for switching patients from antipsychotic drugs to aripiprazole.

A prospective international Aspergillus terreus survey: an EFISG, ISHAM and ECMM joint study

OBJECTIVES

A prospective international multicentre surveillance study was conducted to investigate the prevalence and amphotericin B susceptibility of Aspergillus terreus species complex infections.

METHODS

A total of 370 cases from 21 countries were evaluated.

RESULTS

The overall prevalence of A. terreus species complex among the investigated patients with mould-positive cultures was 5.2% (370/7116). Amphotericin B MICs ranged from 0.125 to 32 mg/L, (median 8 mg/L).

CONCLUSIONS

Aspergillus terreus species complex infections cause a wide spectrum of aspergillosis and the majority of cryptic species display high amphotericin B MICs.

Influence of physical exercise on baroreceptor sensitivity during pregnancy

BACKGROUND

Baroreceptor sensitivity (BRS) refers to the magnitude of change in the heart rate in response to change in blood pressure (e.g. upon standing). The impact of regular antenatal exercise on maternal BRS is unclear.

AIMS

To determine whether supervised weekly exercise influences BRS, and to determine if posture and calculation method are important in antenatal BRS measurement.

STUDY DESIGN AND SUBJECTS

Eighty-one healthy pregnant women were randomly assigned to an exercise or control group. The exercise group attended weekly classes from the 20th week of pregnancy onwards.

OUTCOME MEASURES

Cardiovascular assessments (beat-to-beat blood pressure, heart rate) were performed at 12-16, 26-28, 34-36 weeks and 12 weeks following birth. BRS was calculated using two methods ("sequence" and "beat-to-beat").

RESULTS

Fifty-one women (63%) completed the study. Mean BRS reduced progressively in all women (p < 0.025) and was lowest in those who exercised (0.046 < p < 0.002). Postnatal increases in BRS were independent of posture. Training-induced BRS (beat-to-beat) reduction occurred earlier than BRS (sequence), and only BRS (sequence) was affected by posture. Heart rate variability reduced with advancing gestation (p < 0.002) and was more pronounced in the exercise group (p < 0.029).

CONCLUSIONS

Weekly exercise exaggerated the reductions in BRS and HRV during pregnancy and is likely linked to diminished parasympathetic activity.

Influence of antenatal physical exercise on heart rate variability and QT variability

OBJECTIVE

We sought to characterise the influence of an antenatal exercise programme on ECG-derived cardiac variables.

METHODS

Fifity-one healthy pregnant women were recruited and randomly assigned (2 × 2×2 design) to an exercise group or a control group. Exercising groups attended weekly classes from the 20th week of pregnancy onwards. Cardiovascular assessments (heart rate variabiliy (HRV), QT, and the QT variability index (QTVI)) were performed at 12-16, 26-28, 34-36 weeks and 12 weeks following birth, during supine rest and exercise conditions.

RESULTS

Advancing gestation was associated with an increased maternal heart rate (p = 0.001), shorter QT interval (p = 0.003), diminished HRV (p = 0.002) and increased QTVI (p = 0.002). Each of these changes was reversed within 12 weeks postpartum (p < 0.004). The Exercise group displayed exaggerated changes for all variables (except QT) but only during supine rest in the third trimester (p < 0.029).

CONCLUSION

Advancing gestation is associated with a shift in HRV/QTVI towards values that have been associated with an elevated risk of arrhythmia. A 20-week exercise programme undertaken between mid and late pregnancy exaggerated these changes during rest in the third trimester of pregnancy.

Recruitment of pregnant women to an exercise-intervention study

We share here our experience of recruiting pregnant women into an exercise intervention study. Recruitment challenges were anticipated owing to the study design, which required four hospital visits for cardiovascular assessment, a long-term (nine-month) commitment, and adherence to a 20-week exercise programme. Fifty-three women were assigned to one of three groups (no-exercise, land exercise or water exercise) using a 2 × 2 × 2 flexible randomisation design. Seven hundred forty-four women were screened at an antenatal clinic, of whom 501 were eligible to participate in the study. One hundred forty-five women were subsequently approached: 46 (32%) of whom agreed to participate, 42 (29%) were interested but then declined and 57 (39%) declined outright. Our study design helped recruit pregnant women as it allowed them some choice of group membership. We also noted that the participant-researcher relationship is important in reducing attrition. Our experience provides indications of likely recruitment and attrition rates for future randomised controlled trials of this type.

Changes in heart rate variability and QT variability during the first trimester of pregnancy

The risk of new-onset arrhythmia during pregnancy is high, presumably relating to changes in both haemodynamic and cardiac autonomic function. The ability to non-invasively assess an individual's risk of developing arrhythmia during pregnancy would therefore be clinically significant. We aimed to quantify electrocardiographic temporal characteristics during the first trimester of pregnancy and to compare these with non-pregnant controls. Ninety-nine pregnant women and sixty-three non-pregnant women underwent non-invasive cardiovascular and haemodynamic assessment during a protocol consisting of various physiological states (postural manoeurvres, light exercise and metronomic breathing). Variables measured included stroke volume, cardiac output, heart rate, heart rate variability, QT and QT variability and QTVI (a measure of the variability of QT relative to that of RR). Heart rate (p < 0.0005, p < 0.0005, p < 0.0005) and cardiac output (p = 0.043, p < 0.0005, p < 0.0005) were greater in pregnant women in all physiological states (respectively for the supine position, light exercise and metronomic breathing state), whilst stroke volume was lower in pregnancy only during the supine position (p < 0.0005). QTe (Q wave onset to T wave end) and QTa (T wave apex) were significantly shortened (p < 0.05) and QTeVI and QTaVI were increased in pregnancy in all physiological states (p < 0.0005). QT variability (p < 0.002) was greater in pregnant women during the supine position, whilst heart rate variability was reduced in pregnancy in all states (p < 0.0005). Early pregnancy is associated with substantial changes in heart rate variability, reflecting a reduction in parasympathetic tone and an increase in sympathetic activity. QTVI shifted to a less favourable value, reflecting a greater than normal amount of QT variability. QTVI appears to be a useful method for quantifying changes in QT variability relative to RR (or heart rate) variability, being sensitive not only to physiological state but also to gestational age. We support the use of non-invasive markers of cardiac electrical variability to evaluate the risk of arrhythmic events in pregnancy, and we recommend the use of multiple physiological states during the assessment protocol.

Effect of solvents on the accuracy of the Mini Root ZX apex locator

AIM

To evaluate ex vivo, the effects of three solvents on the accuracy of a contemporary electronic root canal length measurement device (ERCLMD), the Mini Root ZX.

METHODOLOGY

The actual working length (AWL) of 56 extracted maxillary incisor teeth were measured with an ERCLMD. All root canals were prepared with the ProTaper system to AWL. Of them, 20 were filled with gutta-percha and a resin-based sealer (Group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (Group B), and 16 roots were used as the control group (Group C). Removal of the root filling and repreparation processes were performed using the ProTaper system. Guttasolv and Resosolv were used as the solvents in Group A and Guttasolv and Endosolv E in Group B. After the removal of the root fillings had been achieved, the same ERCLMD was used to measure the working length (WL). Differences between AWL and WL measurements were analysed by paired t-test, and the accuracy of ERCLMD was assessed using chi-squared tests.

RESULTS

There were significant differences between AWL and WL measurements in subgroups A2 (Resosolv group) and B2 (Endosolv E group). In these subgroups, WL was shorter than AWL (P < 0.05). Also, the accuracy of the Resosolv group was significantly lower than the others (P < 0.05) at a ±0.5 mm margin of error.

CONCLUSIONS

Removing root fillings may require use of a solvent. In these cases, ERCLMDs may exhibit a lower accuracy, thus operators must exercise additional care when measuring the working length using ERCLMDs.

Distribution of psychiatric symptoms among young Turkish males and the relationship between these symptoms and socio-demographic characteristics

OBJECTIVE

Youth is a period during which individuals undergo rapid physical and psychological changes in their transition from childhood to adulthood. This study aimed to determine the psychological problems of young males from different socio-cultural backgrounds living in different cities of Turkey and to examine the socio-cultural factors possibly associated with these problems.

METHODS

The study was conducted in six different cities in Turkey with the participation of 3655 young male adults. Participants were administered a questionnaire to collect socio-demographic data such as age, marital status, educational background, the history of smoking and alcohol use, income level, occupation, place of residence and the history of chronic disease and allergies. Psychological symptoms were detected via the Symptom Check List (SCL-90 R). The study data were transferred to the SPSS-15 database for statistical analysis.

RESULTS

The median age of the participants was 20.49±1.48years (20-29 age range, median age=20). Based on the SCL-90 R scores, the mean General Symptom Index (GSI) score of the study participants was found to be 0.44±0.27 (0.00-2.61). 13.5% of the participants (n=493) were recorded to have above-the-average GSI scores (≥1.0). Occupation, smoking and alcohol use were found to effect depression. Factors effecting anxiety were occupation, smoking, alcohol use and place of residence.

CONCLUSION

Psychological symptoms that young people suffer from can be diagnosed at early stages and the psychological problems that are triggered by these symptoms can be prevented with the help of such questionnaires. These questionnaires can easily be administered in primary care settings.

Total anomalous pulmonary venous connection: impact of prenatal diagnosis

OBJECTIVES

To investigate whether prenatal screening is effective in the detection of total anomalous pulmonary venous connection (TAPVC) and to identify common prenatal features.

METHODS

This was a retrospective collaborative study involving 19 pediatric cardiac centers in the UK, Ireland and Sweden. Cases with TAPVC born between January 1, 1998 and December 31, 2004, and prenatally diagnosed cases whose estimated dates of delivery were within this time frame, were identified. Cases with functionally univentricular circulation or atrial isomerism were excluded. All available data and stored images were reviewed.

RESULTS

Four-hundred and twenty-four cases with TAPVC were identified prenatally or postnatally, of whom eight (1.9%) had a prenatal diagnosis of TAPVC. Median gestational age at fetal diagnosis was 26 + 6 (range, 22 + 4 to 32 + 0) weeks. Six further fetuses with TAPVC had an abnormality diagnosed on prenatal ultrasound, but not the TAPVC. This included other congenital heart defects (four cases) and isolated pleural effusion (two cases). Seventeen (4.0%) of the 422 liveborn infants had a first-degree relative with congenital heart disease; and six of 17 had a sibling with TAPVC. Two died in utero. Of the liveborn infants diagnosed prenatally with TAPVC, none required urgent intervention for pulmonary venous obstruction and all were alive and well at a median of 2.3 (range, 1.0-7.0) years after surgical repair.

CONCLUSION

Prenatal diagnosis of TAPVC is infrequent using current screening methods. Where there is a family history of TAPVC, specialized fetal echocardiography at 20 and 28 weeks' gestation may be indicated.

Increased frequency of anxiety, depression, quality of life and sexual life in young hypogonadotropic hypogonadal males and impacts of testosterone replacement therapy on these conditions

Hypogonadotropic hypogonadism is defined as the failure in production of gonadal hormones, thus resulting in lower amounts of testosterone. Depression, anxiety and decreased quality of life are the most common psychopathological conditions in young hypogonadal men. The aim of the present study was to assess the still debated relationship with testosterone levels and psychological symptoms in young male patients with congenital hypogonadotropic hypogonadism (CHH). Thirty-nine young male patients with CHH and 40 age-matched healthy males were enrolled in the present study. The impact of testosterone replacement treatment (TRT) on the patients' anxiety and depression levels, sexual function and quality of life were assessed before and after 6 months of treatment using valid and reliable scales, including the Short Form-36 (SF-36), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Arizona Sexual Experiences (ASEX). Patients with CHH had significantly higher scores for BDI, BAI, and ASEX than the control subjects at baseline (p=0.011, p=0.036, p<0.001, respectively). The ASEX and BDI scores significantly improved after the TRT (p<0.001 for both), while the improvement in the BAI score was not statistically significant (p=0.135). When compared to the control group, treatment naïve hypogonadal patients had more severe symptoms of sexual dysfunction, anxiety, depression, and worse quality of life. After 6 months of TRT, we observed improvements in the above parameters, suggesting that low endogenous levels of testosterone might be related to the increased incidence of psychological symptoms.

Plasma asymmetric dimethylarginine (ADMA) concentrations in patients with first and multiple episode schizophrenia

An increasing number of reports in the literature indicate that asymmetric dimethylarginine (ADMA) regulates nitric oxide generation in numerous disease states. ADMA has been less studied in psychiatric disorders. The purpose of this study was to determine plasma ADMA concentrations in patients with schizophrenia compared to healthy controls. The study was conducted in 49 male patients with schizophrenia and 30 healthy male control subjects. The patient group was 24 first episode and 25 multiple episode schizophrenia participants. All schizophrenic patients were administered the Scale for the Assessment of Negative Symptoms, the Scale for the Assessment of Positive Symptoms (SAPS) and the Brief Psychiatric Rating Scale. Measurement of plasma concentrations of ADMA was accomplished by HPLC. There was a significant increase in the plasma ADMA concentrations in patients with schizophrenia when compared to healthy controls. There were no significant correlations between the plasma concentrations of ADMA and scores of psychiatric rating scales. In the multiple episode schizophrenia subgroup, the mean plasma ADMA concentration was significantly higher than in the first episode schizophrenia subgroup. The study indicate that plasma ADMA concentrations in patients with schizophrenia are elevated.

Serum haptoglobin levels in patients with melancholic and nonmelancholic major depression

BACKGROUND

Major depression (MD) is accompanied by systemic immune activation or an inflammatory response with the involvement of phagocytic cells, T cell activation, B cell proliferation, and an acute phase response with increased levels of positive and decreased levels of negative acute-phase proteins. In this study, we aimed to determine any differences in serum haptoglobin (Hp) concentrations among patients with melancholic and nonmelancholic MD and the healthy controls.

METHODS

This study involved 125 male patients who were admitted to the Department of Psychiatry, Gulhane Military Medical Academy (GMMA), in Ankara, Turkey. They were diagnosed with MD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and agreed to participate in the study. The melancholic group consisted of 37 patients and the nonmelancholic group had 45 patients. A healthy control group of 40 subjects was selected from the staff of GMMA. These subjects had not had any lifetime psychiatric diagnosis or psychiatric treatment in their medical histories. Peripheral venous blood samples were obtained from the patients and the control group for a complete blood count, routine biochemistry, and the detection of serum Hp levels.

RESULTS

There was no statistically significant difference among the melancholic MD, the nonmelancholic MD, and the healthy control groups in terms of age, level of education, and gender. Serum Hp concentrations are significantly higher in melancholic patients as compared with non-melancholic depressed patients and controls. However, there was no statistically significant difference between the nonmelancholic MD and the control group in terms of Hp concentrations.

CONCLUSION

The results of this study are important in terms of showing different serum Hp concentrations in patients with melancholic and nonmelancholic MD.

Relationship between trait anxiety, dental anxiety and DMFT indexes of Turkish patients attending a dental school clinic

The aims of this study were to evaluate possible relationships between trait anxiety, dental anxiety and the total number of decayed, missing and filled teeth (DMFT) index of patients attending a dental school clinic. A sample of 558 patients was surveyed with the Turkish version of the Spielberger Trait Anxiety Inventory and Dental Anxiety Scale. DMFT index was calculated by clinical and radiographic examination. A significant linear correlation was observed between trait and dental anxiety, but there was no correlation between DMFT index, trait anxiety and dental anxiety. Trait anxiety has an impact on dental anxiety, but does not affect the DMFT index.

Lamotrigine as an augmentation agent in treatment-resistant obsessive-compulsive disorder: a case report

Obsessive-compulsive disorder (OCD) is a relatively common, often chronic and disabling disorder with high rates of partial and/or absent response to standard, recommended treatments. We report a case of treatment-resistant OCD that was successfully treated with a pharmacological augmentation of lamotrigine plus clomipramine. The patient, a 59-year-old woman, was on a stable dose of clomipramine (225 mg/day) when she was started on lamotrigine (up to 150 mg/day). After 10 weeks of this treatment, her clinical condition remarkably improved, as indicated by a significant decrease of the Yale-Brown Obsessive-Compulsive Scale. This case suggests some preliminary evidence that the addition of glutamatergic agent lamotrigine may be useful in treatment-resistant OCD. However, further controlled studies are needed to support this finding.

Computed tomographic pulmonary angiography in the assessment of severity of acute pulmonary embolism and right ventricular dysfunction

BACKGROUND

The distinction between severe pulmonary embolism (PE) and right heart dysfunction is important for predicting patient mortality.

PURPOSE

To identify the role of computed tomographic pulmonary angiography (CTPA) in the assessment of the severity of acute PE and right ventricular dysfunction.

MATERIAL AND METHODS

Eighty-five patients suspected of having PE, as diagnosed by CTPA and scintigraphy, were divided into three groups: hemodynamically unstable PE (HUPE) (n = 20), hemodynamically stable PE (HSPE) (n = 33), and no PE (n = 32). For each patient, obstruction scores, including short-axis diameters of the right ventricle (RV) and left ventricle (LV), main pulmonary artery, and superior vena cava (SVC), were measured. The RV/LV short-axis ratios were calculated. The shapes of the interventricular septum and the reflux of the contrast medium into the inferior vena cava (IVC) were evaluated. The mortality due to PE within a 1-month follow-up period was recorded.

RESULTS

The median CTPA obstruction score (HUPE 64%, HSPE 28%, P < 0.001), median RV/LV short-axis ratio (HUPE 1.4, HSPE 1.0, P < 0.01), median RV diameter (HUPE 55 mm, HSPE 42 mm, P < 0.001), median SVC diameter (HUPE 23 mm, HSPE 19 mm, P < 0.01), interventricular septum convex toward the LV (HUPE 70%, HSPE 18%, P < 0.001), and reflux of the contrast medium into the IVC (HUPE 65%, HSPE 33%, p < 0.05) were significantly different between the HUPE and HSPE groups. With ROC analysis, the CTPA obstruction score and RV/LV short-axis ratio threshold values for the HUPE patients were calculated to be 48% (95% sensitivity, 76% specificity) and 1.1 (85% sensitivity, 76% specificity), respectively. Three patients in the HUPE group died within the first 24 hours. Logistic regression methods revealed only the RV diameter as a significant predictor of death (odds ratio 1.24; 95% CI 1.04-1.48; P = 0.01).

CONCLUSION

This study found that the parameters useful for distinguishing HUPE and HSPE included CTPA obstruction score, RV and SVC diameters, RV/LV short-axis ratio, interventricular septum shape, and reflux into the IVC. RV dilatation may be a significant predictor for mortality.

Lack of association between DRD3 gene polymorphism and response to clozapine in Turkish schizoprenia patients

It is hypothesized that molecular components of dopaminergic system, especially the dopamine D3 receptor gene (DRD3), may play a crucial role in the pathophysiology of schizophrenia, because it is abundant in the limbic system of the brain and it binds antipsychotic drugs. Several groups attempted to find an association between a serine-to-glycine polymorphism of the DRD3 gene (Ser9Gly) and schizophrenia; however, the results were inconsistent. In this study, we aimed to investigate the relationship of the Serine/Glycine polymorphism of the DRD3 gene with therapeutic response to clozapine treatment between Turkish schizophrenia patients (N = 92) and healthy controls (N = 100). Genotype groups were comparable in BPRS, SAPS, SANS analysis of response to clozapine. Our results suggest that an association between the Ser/Gly polymorphism of DRD3 gene and response to clozapine in Turkish schizophrenia patients is unlikely to exist.

Specific characteristics of suicide attempts in patients with schizophrenia in Turkey

BACKGROUND

Suicide attempt is a universally observed human behavior related to bio-psychological, social and cultural factors. While some studies have suggested that specific demographic/cultural and clinical variables are associated with suicide attempts in schizophrenia, these associations are often inconsistent.

OBJECTIVES

The aim of this study was to investigate the possible association between socio-demographic and clinical variables and suicidal behavior in a sample of patients diagnosed as having schizophrenia in Turkey.

METHODS

Three hundred patients with a SCID-I diagnosis of schizophrenia were studied. The sample was subdivided into two groups based on the presence or absence of lifetime suicide attempts. The main demographic and clinical variables retrospectively collected were analyzed and compared between the two groups.

RESULTS

The results of present study revealed that the subjects who had and had not attempted suicide did not differ with respect to demographic variables. The suicide attempters tend to have younger age at onset of disorder, longer duration of psychosis, more hospitalizations, are more likely to have lifetime major depressive episodes, and a significantly higher rate of alcohol abuse or dependence than patients without a lifetime history of suicide attempts.

CONCLUSIONS

Consistent with the results of previous studies, it has been found that demographic variables may be less valuable predictors of suicidal behavior than clinical variables. These results lead to the idea that socio-cultural variations may not be a critical determinant for suicide attempt among patients with schizophrenia.

Mirtazapine augmentation in depressed patients with sexual dysfunction due to selective serotonin reuptake inhibitors

OBJECTIVE

To evaluate the effect of mirtazapine augmentation in patients with sexual dysfunction induced by current selective serotonin reuptake inhibitor (SSRI) treatment.

METHODS

Forty-nine outpatients in remission from major depressive disorder with SSRI treatment and experiencing treatment-emergent sexual dysfunction were invited to participate and 33 (25 women and 8 men) were included in this 8-week open-label study. All patients continued her/his current SSRI treatment (dosages unchanged) and started on mirtazapine augmentation of 15 mg/day during the first week and 30 mg/day throughout the rest of the study. The Hamilton rating scale for depression (HAM-D), the psychotropic-related sexual dysfunction questionnaire (PRSexDQ), and the Golombok and Rust Inventory of Sexual Satisfaction (GRISS) were given to all patients at baseline and at each follow-up (end of the first, second, fourth, sixth, and eight weeks).

RESULTS

Mirtazapine augmentation led to significant reductions in HAM-D, PRSexDQ, and GRISS scores throughout the study especially after week 4 and 48.5% of patients (n = 16) reported that they had no overall sexual dysfunction at the end of the study.

CONCLUSIONS

Mirtazapine augmentation is a good choice for the treatment of SSRI-induced sexual dysfunction, and the results are typically seen later after 4-8 weeks.

An unusual presentation of sirolimus associated cough in a renal transplant recipient

Sirolimus-associated pulmonary problems are rare but life threatening. Pulmonary problems due to sirolimus treatment are interstitial pneumonitis, bronchiolitis obliterans organizing pneumonia (BOOP), and alveolar hemorrhage. We present a case of sirolimus-related cough in the absence of any pulmonary radiological findings. A 55-year-old man with a history of 4 years of hemodialysis therapy because of end-stage renal disease of unknown etiology underwent cadaveric renal transplantation in June 2006. Three days following the initiation of sirolimus therapy he complained of dry cough and fever. There were no clinical or laboratory findings compatible with specific pulmonary disease. After switching sirolimus to tacrolimus, the cough improved within 1-2 days and resolved in 5 days. Sirolimus should be considered in the differential diagnosis of pulmonary problems in the early posttransplantation period even in the absence of radiological findings.

Body dysmorphic disorder in patients with borderline personality disorder: prevalence, clinical characteristics, and role of childhood trauma

OBJECTIVE

The prevalence of body dysmorphic disorder (BDD) in patients with borderline personality disorder (BPD) is unidentified. We hypothesised that BDD would be more common than realised in patients with BPD and comorbidity with BDD would result in a more severe clinical profile. Also, childhood trauma may play a predictive role in this association.

METHODS

The study included 70 BPD in-patients and 70 matched healthy controls. The subjects were evaluated with a comprehensive assessment battery using Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) diagnostic tool for BDD, Global Assessment of Functioning, Traumatic Experiences Checklist and Hamilton Depression Rating Scale.

RESULTS

The prevalence of BDD was 54.3% in the borderline sample. The BPD patients with BDD had significantly lower overall functioning and higher levels of BPD pathology, childhood traumatic experiences, suicide attempts, substance abuse and self-mutilation than those without BDD. Traumatic experiences were significant predictor of comorbid BDD diagnosis in BPD patients.

CONCLUSIONS

Our results suggest a relatively high prevalence of BDD among patients with BPD, and co-occurrence of BDD and BPD remains to be clarified. The additional diagnosis of BDD in patients with BPD may cause a more severe global illness, and these two disorders may share, at least partly, a common psychopathologic mechanism.

Cardiac risk factors for dental procedures: knowledge among dental practitioners in Wales

OBJECTIVES

To determine knowledge and educational needs of dental practitioners in Wales regarding congenital or acquired cardiac disease and the provision of antibiotic prophylaxis.

DESIGN

Self-administered postal questionnaire.

SETTINGS

Cardiff University Dental Hospital, district general hospitals (HDS), all general dental practices (GDP) and community dental service (CDS) clinics throughout Wales. Methods A questionnaire sent to 1,182 dentists in Wales in 2004-5.

RESULTS

528 questionnaires were returned (a response rate of 45%). These were analysed using one-way analysis of variance to compare summary scores between the occupation groups. Significant differences in knowledge of cardiac risk factors for infective endocarditis and for dental procedures requiring cover were observed between the occupation groups. The majority of dentists (92% GDPs, 94% CDS and 77% HDS) requested postgraduate education in cardiac risk factors and laminated flow diagrams for their surgeries as the preferred educational format.

CONCLUSION

The knowledge of Welsh dentists regarding cardiac conditions or procedures which are risk factors for paediatric and adult patients varied according to place of work. The study identified potential for under- and over-prescription of antibiotic prophylaxis within the current guidance. There was confusion as to which patient groups and cardiac conditions required prophylaxis and for which particular dental procedures. Postgraduate education detailing advances in cardiology practice is necessary for dentists.

Clinical predictors of therapeutic response to clozapine in a sample of Turkish patients with treatment-resistant schizophrenia

BACKGROUND

Several lines of evidence suggest that clozapine is more effective than both first- and second-generation antipsychotic drugs in treatment-resistant schizophrenia (TRS). However, clinicians appear to be hesitant to prescribe this drug. It would therefore be extremely valuable if predictors of response to clozapine could be identified. The aim of this study was to evaluate the predictive factors of clinical responses to clozapine in a group of Turkish patients with TRS.

METHODS

This was a 16-week uncontrolled open study carried out among 97 TRS patients (80 males and 17 females; DSM-IV diagnosis). All patients fulfilled the criteria for refractory schizophrenia according to the UK guidelines for the National Institute of Clinical Excellence (NICE). After all previous antipsychotic medications had run their course, the patients were started on clozapine according to a standardized titration and dosage schedule. Psychopathology was evaluated before the initiation of clozapine therapy and once every 4 weeks using the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment for Positive Symptoms, and the Scale for the Assessment of Negative Symptoms.

RESULTS

Of the TRS patients on clozapine, 55.7% achieved a clinical response, defined as at least a 20% decrease in BPRS. We observed a favorable effect of clozapine on both positive and negative symptoms. Logistic regression analysis showed that a good clozapine response was more likely when schizophrenia began at a later age, when negative symptoms were severe, and when patients had an early response at 4 weeks.

CONCLUSION

A combination of demographic, baseline clinical, and acute treatment response variables may accurately predict response to clozapine in TRS. Priority should be given to initiating clozapine at the earliest phase of TRS, especially for patients with evident negative symptoms.

Acute pulmonary edema secondary to long-term use of oral ritodrine in a woman with a triplet pregnancy

A 28-year-old primigravida who had taken oral ritodrine for 5 months to stop premature uterine contractions and was admitted in labor in the 33rd week of pregnancy developed acute pulmonary edema after cesarean section. Although parenteral ritodrine is the beta-adrenergic agent used most extensively to treat premature labor, only 1 case of pulmonary edema associated with long-term use of oral ritodrine had been reported so far. The present report presents for the first time computed tomographic findings of acute pulmonary edema secondary to tocolytic therapy.

Effect of Dissociative Experiences on Drug Treatment of Panic Disorder

BACKGROUND AND OBJECTIVE

Dissociative experiences are widespread among patients with panic disorder and have a negative impact on cognitive-behavioural therapy. In this study we aimed to investigate whether or not dissociative experiences affect response to drug treatment for panic disorder.

METHODS

Thirty-five patients, 20 women and 15 men, with a mean age of 35.4 years and a diagnosis of panic disorder, were enrolled in the study. Paroxetine 20 mg/day was administered over 6 weeks. Patients were assessed on the Dissociative Experience Scale (DES) and Panic and Agoraphobia Scale (PAS) at the commencement of therapy, and on the PAS again after therapy.

RESULTS

The average DES score was determined as 30.3. Agoraphobia was identified in 34.3% of patients. DES scores were higher in patients with agoraphobia than in those without agoraphobia. Agoraphobia scores were higher in patients with high DES scores. When patients were divided into those with low DES scores (< or =30) and those with high DES scores (>30), a decrease in PAS scores with treatment was observed in both groups, but the decrease was greater in those with low DES scores (18.8 +/- 6.8 vs 5.7 +/- 5.7 in the high-DES score group; Z = 4.486, p = 0.00000053). Similarly, while a decrease in PAS scores with treatment was observed both in patients with agoraphobia (p < 0.05) and in those without agoraphobia, PAS scores decreased more in non-agoraphobic patients (16.7 +/- 7.5 vs 4.8 +/- 6.6 in patients with agoraphobia; Z = 3.799, p = 0.000047). In addition, the decrease in PAS scores was significantly correlated with baseline DES score (beta = 0.706, T = 5.727, p = 0.0000022).

CONCLUSION

This study shows that dissociative experiences reduce the response to drug therapy in patients with panic disorder.

Diarrhea in neutropenic patients: a prospective cohort study with emphasis on neutropenic enterocolitis

BACKGROUND

Although diarrhea is a frequent complication in neutropenic patients, its true incidence, risk factors and clinical course have not been investigated prospectively.

PATIENTS AND METHODS

The study was carried out at Hacettepe University Hospital for Adults and involved patients over 16 years of age. Patients with malignant diseases who were neutropenic on admission or who became neutropenic during their stay in the wards between January 2001 and February 2003 were included. They were monitored daily until discharge, exitus, or recovery from neutropenia-whichever occurred earlier-to monitor the presence of diarrhea and other infections.

RESULTS

A total of 317 neutropenic episodes in 215 patients were followed. Diarrhea was observed in 18.6% episodes, and the incidence of NEC was 3.5%. The etiology in 27% episodes of diarrhea could not be identified. The use of anthracyclines and mitoxantrone increased the incidence of diarrhea. Prior use of penicillin derivatives plus beta-lactam inhibitors and N-imidazoline derivatives was associated with decreased incidence of diarrhea.

CONCLUSIONS

Diarrhea is a common complication in neutropenic patients. Not only specific conditions like NEC, but also nonspecific diseases like parasitosis may be the cause of diarrhea in this patient population.

Epidemiology and outcome of sepsis in a tertiary-care hospital in a developing country

Sepsis continues to have a substantial mortality and morbidity despite advances in the diagnosis and management of this condition. We retrospectively analysed hospital charts of patients diagnosed to have sepsis between January 2002 and June 2003. Demographic characteristics of patients, microbiological findings and predictors of survival were evaluated. Sixty-nine sepsis episodes that occurred in 63 patients were analysed. The most common underlying diseases were hypertension, malignancies and diabetes mellitus. Renal insufficiency, respiratory distress and disseminated intravascular coagulation developed in 52.2, 30.4 and 30.4% of the episodes respectively; 47.7% of the blood cultures yielded an organism. Gram-negative bacteria were the predominant microorganisms (65.9%). Fifty-five patients (87.3%) died. Mechanical ventilation and underlying renal disease were significant determinants of mortality. In conclusion, Gram-negative bacteria remain the major pathogens in sepsis. The mortality remains very high, and a change in the clinical approach to the septic patient should be employed to improve the outcome.

Screening disordered eating attitudes and eating disorders in a sample of Turkish female college students

It has been hypothesized that college women are particularly susceptible to the development and maintenance of disturbed eating behaviors. The purpose of this study was to determine the frequency of disordered eating attitudes and eating disorders in a sample of Turkish female college students. The Eating Attitudes Test was administered to a sample of 414 female college students. The subjects who had a score of 30 or higher were accepted as having disordered eating attitudes, and all of them have been examined using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition for eating disorders. Of the overall sample, 17.1% of subjects were classified as having disordered eating attitudes. This subgroup of subjects was then compared with the remainder on all the other measures. The differences between students with disordered eating attitudes and those without on sociodemographic variables (except for age) were not statistically significant. The rate was 1% for eating disorders including anorexia nervosa (0.5%) and bulimia nervosa (0.5%). This study suggested that the prevalences of disordered eating attitudes and anorexia nervosa among female college students in Turkey were similar to those found in Western societies, but the rate for bulimia nervosa was lower compared with Western societies.

Substance use disorders in men with antisocial personality disorder: a study in Turkish sample

This study investigated the prevalence of substance use disorders (SUDs) and "substance of choice" in 500 male Turkish psychiatric outpatients manifesting a DSM-IV diagnosed antisocial personality disorder (APD) and a SUD diagnoses (the Structured Clinical Interview for DSM-IV). Lifetime SUDs were diagnosed in 86% of APD subjects. Alcohol, cannabis, and inhalant use disorders were the most frequent among substance use, 75.6%, 67.4%, and 35.6%, respectively. This sample's "substance of choice" differed from reported Western populations; a result which may be influenced by socio-cultural variations. The study's limitations are noted.
