Abstract
Background There is an increased risk of long-term dental and periodontal disease in autoimmune bullous diseases (AIBD). Aims In this cross-sectional study, we aimed to determine whether the oral health-related quality of life status (OHRQoL) was associated with disease severity and activity in patients with AIBD. Subjects and Methods 67 patients with AIBD were enrolled in this study. Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) was used to evaluate the disease severity. The score was categorized as a significant course (≥17) and moderate course (<17). Oral health impact profile-14 (OHIP-14) questionnaire was filled to assess the OHRQoL. Self-reported oral health status and oral lesion related pain score were also evaluated in the study group. Results OHIP-14 score was significantly higher in active patients (42.28 ± 13.66) than inactive patients (29.08 ± 12.25) (P = 0.004) and it was correlated with the pain score (6.33 ± 2.78; r = 0.409, P = 0.013). Furthermore, OHIP-14 score was higher in patients with a significant disease course (45.18 ± 15.08) (P = 0.010) than in patients with a moderate course (36.09 ± 9.73). Conclusions OHRQoL may be useful in the disease management and treatment. Since it can be affected by both presence of oral erosions and disease severity, a collaboration between dermatologists and dentists could be crucial to the disease management in AIBD.

Abstract
IntroductionThere is a limited amount of data regarding the relationship between epilepsy and psychiatric symptoms and quality of life (QoL) in children and adolescents.ObjectivesThe aim of this study was to determine the levels of depression, anxiety and attention-deficit hyperactivity disorder symptoms and health-related quality of life (HRQL) in children and adolescents with epilepsy.MethodsThe sample consisted of 75 children with epilepsy and 50 healthy controls aged 8–18 years. Questionnaires were used to evaluate the psychiatric status and HRQL of the patients.ResultsPatients had lower child-rated psychosocial and total area HRQL scores, and lower parent-rated psychosocial, physical and total area HRQL scores than the controls did. Inattention scores of the epilepsy group were significantly higher compared to controls. No significant differences were found between patients and controls in terms of anxiety and depression scores. Regarding determinants of HRQL, severity of depression and anxiety had a decreasing effect on child-rated HRQL total scores; and severity of anxiety had a decreasing effect on parent-rated HRQL total scores.ConclusionsEpilepsy is associated with poor QoL in childhood and severity of depression and anxiety are among the determinants of QoL. Clinicians should be more aware of accompanying psychiatric symptoms in epileptic patients and take the necessary precautions in the early period of the illness in an effort to improve QoL.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
OBJECTIVE Post-pericardiotomy syndrome (PPS) occurs in 10-40% of patients after cardiac surgery. PPS is considered an autoimmune phenomenon. The neutrophil-to-lymphocyte ratio (NLR) is a novel inflammatory marker that is associated with various cardiovascular diseases. Studies have reported that the NLR increases in certain autoimmune diseases. This study examined whether the NLR is helpful to predict the occurrence of PPS after elective on-pump coronary artery bypass graft (CABG) surgery. PATIENTS AND METHODS The records of patients who underwent elective first-time on-pump CABG were reviewed retrospectively. In total, 72 patients with PPS were included in the study, and 100 patients who did not develop PPS were included as the control group. Peripheral blood samples collected preoperatively and on postoperative day 1 were used to calculate the NLR. RESULTS No differences in preoperative white blood cell (WBC) count, neutrophil count, lymphocyte count, or NLR were observed between the patients with PPS and the control group. The WBC (p < 0.001) and neutrophil counts (p < 0.001) and NLR (p = 0.01) were significantly higher during the postoperative period in patients with PPS than in the control group. A receiver operating characteristic curve analysis showed that the postoperative NLR predicted PPS with 60% sensitivity and 59% specificity (area under the curve, 0.61; 95% confidence interval [CI], 0.51-0.70; p = 0.017), using a cut-off of 8.34. The postoperative WBC count (odds ratio [OR], 1.6; 95% CI, 1.36-2.03; p < 0.001) and NLR (OR, 3.3; 95% CI, 1.56-7.01; p = 0.002) were independently associated with PPS. CONCLUSIONS The postoperative NLR may be useful to predict the development of PPS in patients undergoing on-pump CABG.

Abstract
We sought to expose the possible effect of hepatitis C virus (HCV) infection on oxidative stress indicators, nutritional status, and erythropoietin (rHuEPO) requirements in maintenance hemodialysis (MHD) patients. A total of 111 MHD patients (69 males, 42 females; mean age 51.3 +/- 13.0 years; MHD duration 78.5 +/- 52.1 months) and 46 healthy controls were enrolled in the study. We excluded patients with hepatitis B infection or malignancy. Indicators for oxidative status were studied in plasma samples obtained at the beginning of a clinically stable MHD session. Measurements were performed for plasma superoxide dismutase, glutathione peroxidase (antioxidative agents), and malonyldialdehyde (MDA; oxidative agent) by spectrophotometric methods. All patients were analyzed for the presence of anti-HCV; positive patients were also evaluated for the presence of HCV RNA. MHD patients were divided into three groups according to HCV infection status: group I (anti-HCV-positive, HCV-RNA-negative; n = 22); group II (anti-HCV-positive, HCV-RNA-positive; n = 22), and group III (anti-HCV-negative; n = 67). According to the analyses, MHD patients showed higher plasma oxidative stress indicators and lower antioxidative indicator levels compared to controls (P < .0001). MHD patients also displayed lower albumin and higher C-reactive protein (CRP) levels compared to controls (P < .0001). Antioxidant levels were decreased significantly from group I to III (P < .0001). MDA levels significantly increased from group I to III (P < 0.01). HCV-RNA-positive patients showed lowest albumin and highest CRP levels and rHuEPO requirements. Although alanine transferase (ALT) levels were in the normal range, group II patients had significantly higher ALT levels than the other groups (P < .01). In conclusion, we observed negative effects of active HCV infection on oxidative stress and rHuEPO requirements. In contrast, we detected that clinically inactive HCV infection was associated with reduced oxidative stress and rHuEPO requirements compared with active HCV infection and HCV-negative patients.

Abstract
AIMS We sought to evaluate influences of oxidative stress (OS) on rHuEPO requirements in hemodialysis patients without chronic inflammation. METHODS Sixty-eight hemodialysis patients and 46 healthy controls underwent measurements plasma levels of antioxidative agents, such as glutathione peroxidase (GPX), superoxide dismutase (SOD), and oxidative compounds including malonyldialdehyde (MDA). We retrospectively analyzed the last 3 months' rHuEPO requirements, iron indices, and CRP levels. RESULTS Plasma levels for SOD, GPX, and MDA were 974.4+/-216.4 U/gHb, 44.4+/-13.6 U/gHb, 10.0+/-2.0 nmol/mL, respectively yielding results that were different from healthy controls (P<.0001). Increased OS negatively correlated with hemoglobin levels (P<.0001) and positively correlated with rHuEPO requirements (P<.01). Increased antioxidative capacity positively correlated with hemoglobin levels (P<.0001) and negatively correlated with rHuEPO requirements (P<.0001). For further analyses, hemodialysis patients were subgrouped according to rHuEPO requirements as group I (lowest 1/3, n=23), group II (moderate 1/3, n=23) and group III (highest 1/3, n=22). Group III displayed the highest MDA (P<.05), the lowest SOD (P<.0001), and comparable GPX (P<.05) levels. Group III also had the highest CRP and the lowest albumin levels compared with the others (P<.01). CONCLUSION OS has strong adverse influences on rHuEPO responses of HD patients with "normal" CRP levels, but it should not be forgotten that CRP levels in the "normal" range may still reflect ongoing microinflammation.

Abstract
BACKGROUND/AIMS The mutations in the basal core promoter and precore region of hepatitis B virus genome in hepatitis B e antigen-positive and -negative chronic hepatitis B patients have been described. The reports about their prevalence and clinical significance in the Mediterranean region where D is the predominant genotype, are very limited. METHODOLOGY The serum samples were collected from 44 naive chronic hepatitis B patients. For detection of the mutations basal core promoter and precore regions of HBV genome were amplified and sequenced. RESULTS All samples were determined as genotype D. Before initiation of treatment basal core promoter mutations were found as 55% (11/20) and 46% (11/24) in HBeAg-positive and -negative patients, respectively (p > 0.5). HBeAg-negative samples were associated with precore mutations (G1896A and G1899A). Three of 20 (15%) patients of HBeAg-positive and seven of 24 (29%) of HBeAg-negative populations showed sustained response to therapy at the 24th month of initiation. CONCLUSIONS The presence of precore stop codon mutant in those with sustained response was 89%, overall at the end of therapy. At initiation of therapy basal core promoter mutations were more common in non-responders than responders (65% vs. 20%; p < 0.001). While 23% of cases totally showing sustained response, absence of mutations in the basal core promoter region of hepatitis B virus genotype D may be related to sustained response in patients with chronic hepatitis B.

Abstract
Hyperuricemia is a common complication in renal transplant recipients, and uric acid (UA) may play a role in renal dysfunction. The aim of this study was to evaluate the effects of UA on chronic allograft nephropathy (CAN) in renal transplant recipients. The 133 study subjects included 34 women and 99 men of overall mean age of 34.7 +/- 9.9 years. They underwent renal transplantation between 1998 and 2000. Serum UA levels were measured in the first month after transplantation and then at yearly intervals throughout a 3-year follow-up. In the first month after transplantation, 55.3% of recipients had hyperuricemia (UA >7 mg/dL in men; UA >6 mg/dL in women), but, 3 years after transplantation, 84.6% of the subjects had that disorder (P<.001). CAN was diagnosed in 31.5% of the patients at a mean onset of 31.8 +/- 14.3 months after transplantation. Fifty-two percent of these individuals experienced graft failure within 43.3 +/- 20.8 months after transplantation. UA levels were recorded before the development of CAN. There was no association between UA levels and CAN according to a Cox regression analysis (P>.05; relative risk, 1.082; 95% confidence interval [CI] 0.9-1.3). We concluded that the prevalence of hyperuricemia was higher among recipients than in healthy individuals, but that the UA level did not affect the development of CAN during first 3 years after transplantation.

Abstract
Cytomegalovirus (CMV) infection is a risk factor for arteriosclerosis in renal transplant recipients. We sought to investigate the effects of CMV infection on atherosclerotic events (AE) in renal transplant recipients. This retrospective analysis included 200 patients: 52 women and 148 men of overall mean age of 36.18 +/- 10.23 years who were transplanted at our center between 1998 and 2001. We analyzed demographic features, dialysis duration, diabetes, blood pressure level, body mass index (BMI), medications, and lipid parameters. CMV infection was diagnosed in 23.5% of patients in the first 2 years after transplantation; these patients were followed for 4 years. All patients had been assessed for AE, including previous myocardial infarction, angina, revascularization procedures, intermittent claudication, stroke, or transient ischemic attack. AE occurred in 13% during the follow-up period. CMV infection was more frequent among these patients compared to those without AE, namely 42.3% versus 20.6%, respectively. Although the gender, dialysis duration, serum cholesterol level, presence of acute rejection, and BMI were not associated with AE, age, hypertension, and CMV infection did show a relation. A multivariate analysis by logistic regression revealed mean age and CMV infection to be independent risk factors for AE: odds ratio (OR)=5.6, 95% confidence interval (CI)=1.3 to 24.6 (P=0.02) and OR=4, 95% CI = 1.3 to 12.3 (P=.01). This study suggested that the presence of CMV infection may be a triggering factor for AE in renal transplant recipients.

Abstract
BACKGROUND Vitamin D receptor (VDR) gene polymorphisms have been widely studied, especially to analyze their effects on calcium-phosphorus metabolism and secondary hyperparathyroidism in patients on dialysis. In this study, we sought to investigate the possible effects of these polymorphisms on the anemia of renal failure and recombinant human erythropoietin (rHuEPO) responses among patients receiving hemodialysis. METHODS One hundred twenty-eight patients (52 females/76 males) underwent genotyping for the insertion/deletion Bsml (B-->b, restriction site, exon VIII-->IX) and Tagl (T-->t, 352 exon IX) VDR gene polymorphisms. The mean value of the last 6 months' monthly evaluated laboratory values (C-reactive protein, hemoglobin, iron indices, PTH, and albumin) and clinical findings (rHuEPO requirement, cumulative iron supplementation doses, and body weight) were analyzed retrospectively excluding patients with chronic inflammation, hemolytic anemia, or active blood loss such as gastrointestinal bleeding. RESULTS Mean age and dialysis durations were 41.5 +/- 11.8 years and 91.8 +/- 45.3 months, respectively. Polymorphism percentages were as follows: Bsml; BB/Bb/bb: 32.2/63.6/4.2 and Tagl; TT/Tt/tt: 40.5/55.4/4.1%, respectively. BB variant of Bsml gene was related to lower rHuEPO needs (P < .05) and also higher hemoglobin levels (P < .005) when compared with the Bb/bb variant. Considering Tagl variants, transferrin saturation levels were lower (P < .03) among patients with the Tt/tt variant, but there was no other significant difference in the mean values of other data between TT and Tt/tt variants. CONCLUSION The BB variant of Bsml was related to decreased rHuEPO requirements to achieve higher hemoglobin levels among maintenance hemodialysis patients without chronic inflammation.

Abstract
Diabetes mellitus appearing after kidney transplantation--posttransplant diabetes mellitus (PTDM)--is a common complication associated with poor graft and patient survival. The purpose of the current study was to determine the risk factors for developing PTDM in 204 renal transplant recipients who had been followed for at least 30 months. Posttransplant diabetes mellitus was diagnosed according to the American Diabetic Association/WHO criteria, or a requirement for insulin, an oral hypoglycemic agent, or both. Analyses of possible risk factors for PTDM included demographic features, dialysis and posttransplantation duration, smoking, body mass index, medications, co-morbid diseases, HLA mismatches, as well as laboratory metrics of serum creatinine, albumin, calcium, phosphorus, C-reactive protein, parathyroid hormone, and lipid profiles. Twenty-six patients displayed PTDM. Univariate analysis showed that older age, greater body mass index, presence of hepatitis C virus (HCV) infection, and smoking at the time of renal transplantation were associated with PTDM development. In a multivariate analysis, HCV infection, smoking, and patient age at the time of transplantation were independent risk factors for PTDM. In conclusion, the presence of HCV infection or a smoking habit in addition to older age at the time of transplantation were the main predictors for developing PTDM. Patients should be closely followed regarding their smoking habit and weight gain as modifiable risk factors for PTDM.

Abstract
We aimed to define the prevalence of anemia and possible causes for it in a group of renal transplant recipients. A total of 229 recipients (65 women; age 36.1 +/- 11.8 years; minimum posttransplant duration, 3 years) were included. Patients with iron, vitamin B(12), and folic acid deficiencies were excluded. Patients were grouped according to number of posttransplant years completed with functioning grafts (3, 5, or 10 years). Demographic data, donor information, HLA mismatches, acute rejection episodes, biochemical parameters, and medications received during the 3 months before transplant and at 3, 5, and 10 years posttransplant were collected retrospectively. The anemia threshold was 13 g/dL for men and 12 g/dL for women. Anemia prevalence was 41.5%, 35.3%, and 93.2% at 3, 5, and 10 years, respectively. Anemic patients had higher creatinine levels for all years. In the anemic patients, hemoglobin values were lower in the pretransplant period than at 3 and 5 years. Anemic patients had higher HLA mismatches for the same years. Three-year hemoglobin levels were positively correlated with pretransplant hemoglobin and negatively correlated with creatinine levels and HLA mismatches. Five-year hemoglobin levels were positively correlated with pretransplant hemoglobin and albumin levels. Ten-year hemoglobin levels were positively correlated with pretransplant hemoglobin and albumin values but negatively correlated with creatinine levels and HLA mismatches. The prevalence of anemia in renal transplant recipients increases in parallel with posttransplant duration. Hemoglobin levels in these patients are closely related with pretransplant hemoglobin, follow-up creatinine levels, and HLA mismatches.

Abstract
Arteriovenous fistulae (AVF) failure is the most common cause of morbidity and hospitalization in hemodialysis (HD) patients. The purpose of this study was to determine the effects of smoking and blood eosinophil count on the development of AVF thrombosis in HD patients. This cross-sectional study included 141 patients (M/F 80/61; age 43.4 +/- 11.6 years, HD duration 7.7 +/- 4.4 years). The following were analyzed as possible risk factors for AVF failure for all patients: demographic features, dialysis time, smoking, medications, body mass index, comorbid diseases, and various laboratory parameters (whole blood count and serum levels of albumin, calcium, phosphorus, uric acid, C-reactive protein, ferritin, and parathyroid hormone). AVF thrombosis was detected in 60 patients; in contrast, 81 patients had no thrombosis. Distributions of age, gender, and HD duration were similar between both groups. Univariate analysis showed that snuffbox AVF location (P < .0001), higher blood eosinophil count (P < .0001), smoking (P < .01), and higher hematocrit level (P < .05) were all associated with AVF thrombosis. According to multivariate analysis by logistic regression models, eosinophil count (RR = 1.005, P < .05) and snuffbox location (RR = 5.970, P < .05) were predictors of AVF thrombosis. When AVF location was excluded from the analysis, smoking (RR = 4.140, P < .01) and high blood eosinophil count (RR = 1.006, P < .005) were independent risk factors for thrombosis. Our study indicates that smoking and high blood eosinophil count may contribute to the development of AVF thrombosis.

Abstract
The relationship between resistance to rifampicin and rifabutin and genetic alterations in the rpoB gene of 41 rifampicin-resistant isolates of Mycobacterium tuberculosis was evaluated. Although 35 isolates with rifampicin MICs > or = 32 mg/L were also rifabutin-resistant, six isolates with rifampicin MICs of 2-16 mg/L were susceptible to rifabutin (MIC < or = 0.5 mg/L). Mutations Asp516Val, Asp516Tyr, Leu533Pro and the double mutation Met515Ile and Leu533Pro influenced susceptibility to rifampicin, but not to rifabutin. All mutations at codons 531 and 526, except one isolate with a His526Cys mutation, correlated with resistance to both compounds.

Abstract
The aim of this study was to determine the in vitro susceptibility of 170 clinical isolates of Mycobacterium tuberculosis to fusidic acid using a proportion dilution method. Nineteen isolates were resistant to at least one first-line anti-tuberculosis drug. A total of 1.8% of the isolates were resistant to fusidic acid. Fusidic acid should be evaluated clinically as a potential supplementary drug for the treatment of infections due to multidrug-resistant strains of M. tuberculosis.

Abstract
A late complication of the CardioSEAL atrial septal defect (ASD) occluder is reported. Although left atrial umbrella was completely epithelialized and occluded ASD without residual defect, the right atrial umbrella protruded toward the center of right atrium after 18 months. We believe this may be associated with the structural abnormality of the device.

Abstract
We evaluated cord formation in MB/BacT broth as a rapid method for presumptive identification of the Mycobacterium tuberculosis complex. Kinyoun acid-fast-stained smears from 370 positive MB/BacT bottles were examined for the presence of serpentine cording. The smears were examined independently by two observers. Observer 1 (the supervisor of the mycobacteriology laboratory) examined all of the smears while observer 2 (a clinical microbiologist not familiar with acid-fast bacillus [AFB] microscopy) examined 148 randomly chosen smears that were read by observer 1 without knowledge of which smear was which. The sensitivity, specificity, and positive and negative predictive values of cording for the presumptive identification of M. tuberculosis read by observer 1 were 88.2, 97.4, 99.2, and 69.7%, respectively. These values were reported at 90.6, 52.3, 82.8, and 69. 7%, respectively, by observer 2. Our laboratory prevalence of M. tuberculosis among positive cultures was 78% during the time this study was conducted. At the time of positive signal of the MB/BacT bottles, the broth of the bottles had sufficient cell mass to allow for observation of the presence or absence of serpentine cording. The presence of cords in MB/BacT broth is a reliable criterion for rapid, predictive identification of the M. tuberculosis complex for laboratories with a high proportion of the M. tuberculosis complex when the smears are examined by a microbiologist who has experience with AFB staining.

Abstract
The feasibility of using nucleic acid probes directly from positive MB/BacT broth to identify mycobacteria was determined in this study. A total number of 2,727 specimens were cultured into the MB/BacT (Organon Teknika) automated system and on conventional Loweinstein-Jensen (LJ) slants. The Gen-Probe AccuProbe culture identification tests (DNA probes) were used on samples from bottles which were identified as positive for mycobacteria by MB/BacT. Samples of positive MB/BacT broth (0.1 ml) were used directly in the broth culture method for the DNA probes as published by Gen-Probe. Centrifugation of the contents of the bottle was not done prior to probe testing. The number of mycobacteria detected by MB/BacT and LJ was 253 (221 isolates of M. tuberculosis and 32 isolates of mycobacteria other than M. tuberculosis [MOTT]). A total of 96.4% (213 of 221) of the bottles growing M. tuberculosis produced a positive direct DNA probe result for M. tuberculosis complex. One hundred percent (16 of 16) of the bottles growing M. gordonae produced a positive direct DNA probe result for M. gordonae. A total of 3.6% (8 of 221) of the bottles growing M. tuberculosis did not yield a positive direct DNA probe result for M. tuberculosis complex. The testing of subcultures made onto solid media from the positive bottles by AccuProbe identified six of these eight M. tuberculosis isolates. Two (0.9%) M. tuberculosis isolates gave a negative result for the M. tuberculosis probe test applied on the MB/BacT broth and its subculture. The rest of the positive MB/BacT bottles growing MOTT (16 of 32) were negative for M. gordonae, M. avium, M. intracellulare, and M. kansasii probes. The sensitivity and specificity of AccuProbe for the identification of M. tuberculosis and M. gordonae directly from MB/BacT broth were 96.4 and 100% for M. tuberculosis and 100 and 100% for M. gordonae, respectively. The direct testing of positive MB/BacT broth by AccuProbe, without prior centrifugation, allows for the accurate and rapid identification of M. tuberculosis and M. gordonae.

Abstract
OBJECTIVE To determine the efficacy of transcatheter closure of patent arterial ducts using controlled-release coils. DESIGN Transcatheter closure of patent arterial ducts was attempted in 52 patients using controlled-release coils. SETTING For the study, four tertiary paediatric cardiology units were used, two of which were in the U.K., one in Italy and one in Turkey. PATIENTS The 52 patients ranged in age between 3-5 months and 61 years (median 3-5 years), and weighted between 4.5 kg and 62 kg. The duct diameters were 1 mm to 6.5 mm. RESULTS In four patients the ducts were too large for safe release of the coils. In the remaining 48, one coil was inserted in 33 patients, two coils in nine, three coils in four and four coils in two patients. Immediately at the end of the procedure, the duct was completely occluded in 26/47 (55%) patients. Haemolysis occurred in one patient, in whom the coil was removed by a snare catheter and a large umbrella device was implanted with resolution of the haemolysis. Coil embolization to the pulmonary artery occurred in five (10%) patients. All were easily retrieved and replaced by larger coils. At the latest follow-up by colour Doppler echocardiography, the duct was completely occluded in 44/47 (94%) patients. CONCLUSIONS Transcatheter closure of patent arterial ducts by controlled-release coils is effective and safe. Even when more than one coil is inserted the technique is still less cumbersome and considerably cheaper than transcatheter umbrella closure.

Abstract
BACKGROUND Certain types of human papillomavirus (HPV) are shown to be associated with the development of genital lesions. DNA hybridization methods are used for the diagnosis of HPV infections. OBJECTIVE To use a nonradioactive DNA in situ hybridization system for the investigation of HPV infections responsible for the development of genital lesions in women. STUDY DESIGN Sections from archival paraffin embedded biopsy specimens of 59 cases were screened for the presence of HPV DNA sequences by using digoxigenin labeled DNA probe which is specific for all types of HPVs and digoxigenin detection system. The study group consisted of samples diagnosed as squamous hyperplasia of the vulva (group 1), koilocytosis (group 2), condyloma acuminatum/koilocytotic atypy (group 3), cervical intraepithelial neoplasia (CIN), and epidermoid carcinoma (group 4). RESULTS No HPV DNA was detected in groups 1 and 2 which consisted of 3 and 13 specimens respectively. Seven of 11 (63.6%) specimens in group 3 and 7 of 32 (21.9%) in group 4 were found to be positive for in situ HPV DNA. Seven positive samples in group 3 and one positive sample in group 4 were typed as HPV 6/11. Five samples of the remaining positives in group 4 were typed as HPV 16/18. One case was found to be positive with both 16/18 and 31/33. CONCLUSION Nonradioactive DNA in situ hybridization is an easy and efficient method to be performed for the diagnosis of HPV infections. Koilocytosis with atypy is directly correlated with HPV infection and it is suggested to monitor the CIN cases with HPV type 16/18 infection since the pathology can be progressive.

Abstract
Splenic anomalies frequently accompany conotruncal and atrioventricular septal malformations. Asplenia is a major factor in the mortality of newborns with the heterotaxy syndrome, requiring an early and accurate diagnosis. We evaluated the splenic status of five consecutive patients with heterotaxy syndrome by radionuclide splenic scanning with 99mTc-labelled and denatured red blood cells (RBCs) and by real-time abdominal ultrasonography. Examination and comparison of the findings using these diagnostic methods suggest that the former has some diagnostic pitfalls which arise from the symmetrical location of the liver in the abdomen. This leads to difficulty in the interpretation of overlapping signals from the blood pool of the liver and from the spleen.
