RESUMO

PURPOSE: Heart is affected structurally and functionally in end-stage renal disease (ESRD). However, the data available about adverse effects of ESRD on right ventricle (RV) is scarce. We aimed to evaluate echocardiographic parameters of RV in nondiabetic, normotensive patients with ESRD undergoing hemodialysis (HD). METHODS: A total of 45 (24 women; mean age 52.4 ± 12.4 years) consecutive nondiabetic, normotensive patients with ESRD undergoing HD and 39 healthy age and sex-matched control subjects (22 women; mean age 50.3 ± 6.6 years) were enrolled in the study. M-mode and two dimensional images, color, pulsed and continuous wave Doppler, and tissue Doppler measurements were acquired from all subjects. Echocardiographic evaluation was performed in the days between HD dates of the patients. RESULTS: RV fractional area change, tricuspid annular plane systolic excursion, tricuspid E velocity, E/A ratio, tricuspid annular E´ velocity, and E´/A´ ratio were lower in patients than controls (p < 0.001, p = 0.003, p = 0.007, p = 0.005, p < 0.001, and p = 0.034, respectively). However, RV diastolic area, RV myocardial performance index, E/E´ ratio, and mean and systolic pulmonary artery pressure were higher in patients than controls (p < 0.001, p = 0.007, p = 0.005, p < 0.001, p = 0.006, respectively). CONCLUSIONS: RV systolic and diastolic functions of nondiabetic, normotensive HD patients are deteriorated as compared to healthy controls.

RESUMO

BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) is known to be associated with cardiac damage. Brain type natriuretic peptide (BNP) is secreted from stressed myocardium. OBJECTIVES: This study investigated that BNP levels in CCHF and its association with clinical course of disease. METHODS: Consecutive CCHF diagnosis confirmed patients were enrolled to the study. Results of patients were compared with age-sex-matched healthy volunteers. Blood samples for BNP levels were collected from the patients during emergency room applications. Mortality, hospitalization duration and other disease severity predictors (thrombocyte count, hemoglobin, white blood cell count, alanine aminotransferase, aspartate aminotransferase, prothrombin time, lactate dehydrogenase, international normalized ratio, activated partial thromboplastin time) were recorded. These parameters' correlations with BNP levels were analyzed. RESULT: Forty-three CCHF patients and 28 control subjects recruited to the study. Groups were similar for age and gender. There was no mortality. Levels of BNP were found to be significantly higher in patients than control subjects (100.4±45.4 vs. 78.0±40.4, P=0.033). But BNP levels were not correlated with duration of hospitalization and disease severity predictors (P > 0.05). CONCLUSIONS: This study showed that BNP levels are modestly increased in CCHF but this increase does not correlated with disease severity predictors.

RESUMO

BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) is a systemic viral disease that also affects the endothelium. Thrombocytopenia and hemorrhage are seen in this disease. But, the cause of thrombocytopenia is not clear. We hypothesized that endothelium dysfunction may be the cause of thrombocytopenia. We evaluated the endothelium functions by flow-mediated dilatation (FMD) in CCHF. METHODS: Consecutive children with suspected CCHF who applied to our hospital were evaluated for recruitment into the study. FMD analysis was done in the active and healing period of the disease. Diagnosis was confirmed or ruled out by polymerase chain reaction and/or ELISA test. Basal brachial artery diameter (BBAD) and dilated brachial artery diameter (DBAD) after ischemic period were measured and percent dilatations [(DBAD-BBAD)/BBAD, FMD%] were computed from all subjects. RESULTS: Fifty-four children (40 male, mean age 12.4 ± 4.4 years) were recruited into the study. CCHF diagnosis was confirmed in 28 children and ruled out in 26 children. Groups were similar for age and gender. FMD% was significantly decreased in CCHF patients when comparing this with the control patients in the active period (2.65 ± 2.76 vs. 13.76 ± 7.95, P < 0.001). FMD% was correlated with platelet count in the active period of the disease (r = 0.599, P = 0.004). FMD% was recovered in the healing period (2.65 ± 2.76 vs. 14.72 ± 2.66, P < 0.001) and was not significantly different from basal values of control patients (P > 0.05). CONCLUSIONS: FMD is significantly decreased in CCHF and recovers in the healing period. So, endothelium functions are disturbed, and disturbance is correlated with thrombocytopenia in CCHF.

RESUMO

BACKGROUND: Apoptosis is a main regulator in responses of cellular immunity throughout systemic viral infections. Perforin, soluble Fas ligand, caspase-3 and caspase-cleaved cytokeratin-18 (M-30) are mediators of apoptosis. The aim of this study is the evaluation of Crimean-Congo hemorrhagic fever (CCHF) disease changes in the levels of these apoptotic markers and the relation of these changes with disease severity. METHODS: Forty-nine hospitalized children with CCHF and 36 healthy controls were enrolled in this prospective study. The CCHF patients were classified into 2 groups based on disease severity (severe group and nonsevere group). Demographic characteristics and clinical and laboratory findings of all patients were recorded on admission. RESULTS: Serum perforin, caspase-3 and soluble Fas ligand levels were found to be significantly higher both in the severe and nonsevere CCHF groups than the healthy control group (P < 0.05), but there was no significant difference in these apoptotic markers between severe and nonsevere CCHF groups (P > 0.05). In addition, serum M-30 levels did not differ significantly among all groups (P > 0.05). There was a positive correlation between serum values for perforin, caspase-3 and M-30 and the disease's severity criteria such as aspartate aminotransferase and/or alanine aminotransferase. The serum levels of all these markers were negatively correlated with disease severity criteria such as the platelet count. CONCLUSIONS: In this study, we concluded that the interactions of cytolytic granules containing perforin and caspase cascade and Fas-FasL may play an important role in the pathogenesis of CCHF in children.

RESUMO

BACKGROUND: In this study, our aim is to examine the role of the neutrophil to lymphocyte ratio (NLR) in the predictions of recurrence under long-term follow-up in patients whose sinus rhythms (SRs) were restored with amiodarone in acute atrial fibrillation (AF). METHODS: Retrospectively, patients with acute AF, which successfully converted to the SR with amiodarone treatment, were recruited into the study. Patients experiencing the first AF attack were enrolled to the study and followed up for 5 years (median 23 months, 25-75 percentiles 12-24 months). Neutrophil to lymphocyte ratio was computed as absolute neutrophil count divided by lymphocyte count. RESULTS: A total of 218 patients were recruited into the study and followed up for 21.6 ± 13.9 months; 87 (40%) patients had ≥1 recurrent AF attack within this period. The follow-up of 131 (60%) patients resulted in persisted SR without any other AF attack. Groups were similar in terms of age and gender. Left atrium (LA) diameter and NLR were increased, and platelet count and lymphocyte count were decreased in patients with AF recurrence in univariate analysis (P < .05 for all). Only LA diameter (for per mm, 1.077 [1.021-1.136], P = .006) and NLR (1.584 [1.197-2.095], P = .001) were independent predictors of AF recurrence in the multivariate analysis. CONCLUSION: Increased NLR is a marker of increased inflammation and may serve as simple, cheap, and readily available predictors of recurrence in the long-term follow-up of patients admitted with acute AF and successfully converted to SR with amiodarone.

RESUMO

AIMS: To evaluate the safety and efficacy of the new Cera septal occluder (CSO) for atrial septal defect (ASD) closure as compared to the AMPLATZER Septal Occluder (ASO). METHODS AND RESULTS: A total of 405 ASD patients receiving CSO or ASO were studied. The ASDs were classified into simple defects (isolated defects <26 mm) or complex defects (isolated defects ≥26 mm, large defects with a deficient rim, double or multi-fenestrated defects). Clinical and echocardiographic findings were collected before discharge, at one month, and every six months after implantation. Two hundred and five (133 females, aged 30±13 years) and 200 (135 females, aged 28±14 years) patients received CSO and ASO implants, respectively. The CSO group had similar ASD and device sizes, prevalence of complex lesions, procedural times and success rates as compared to the ASO group. Echocardiographic follow-up at one and six months showed similar residual shunts between devices. Both groups had similar rates for device embolisation and atrial arrhythmia. The average equipment cost per patient was lower in the CSO group than in the ASO group (US $3,500 vs. US$5,600, p<0.001). CONCLUSIONS: Transcatheter ASD closure with CSO is safe and effective. It appears to be an attractive alternative to ASO because of its relatively low cost.

RESUMO

Non-dipper blood pressure (NDP) as an indicator of autonomic dysfunction could be associated with hypertensive response to exercise (HRE) in diabetic patients. HRE was determined as a predictor of development of unborn hypertension. We aimed to investigate if any correlation among NDP and HRE in normotensive type 2 diabetic patients. A total of 59 consecutive type 2 diabetic patients without history of hypertension and with normal blood pressure (BP) on ambulatory blood pressure monitoring (ABPM) were enrolled to the study. We divided the study population in to two groups depending on their BP on ABPM as dipper (group 1) or non-dipper (group 2). There were 22 patients (mean age 49.5 ± 7 and 10 male) in group 1 and 37 patients (mean age 53.1 ± 10 and 14 male) in group 2. Daytime diastolic and mean BP of dippers and night time systolic and mean BP of non-dippers were significantly higher. HRE was not significantly different between groups (59% vs. 62%, p = 0.820). Hemodynamic parameters during the exercise test were similar. At multivariate linear regression analysis, resting office systolic blood pressure (SBP) (r = 0.611, p < 0.001), male sex (r = 0.266, p = 0.002) and age (r = 0.321, p = 0.010) were independently correlated with peak exercises SBP. Logistic regression analyses identified the resting office SBP (OR 1.191, 95% CI 1.080-1.313; p < 0.001) and age (OR 1.161, 95% CI 1.038-1.298; p = 0.012) were independent predictors of HRE. This study revealed that HRE is not related with non-dipper BP in diabetic patients. This study could inspire to further studies to explore the main reasons of HRE in diabetes mellitus.

RESUMO

Cytokine networks play a key role in the pathogenesis of the disease in Crimean-Congo Hemorrhagic Fever (CCHF) patients. Therefore, our aim was to study the effects of cytokine levels on the pathogenesis and severity of the disease in children with CCHF. Fifty-two patients diagnosed with CCHF and 34 healthy controls (HC) were included in the study. The patients with CCHF were divided into two groups (severe and non-severe). The levels of the Interleukin-10 (IL-10), IL-12, IL-6, Endothelin-1 (ET-1) and tumor necrosis factor-α (TNF-α) were measured in all groups. IL-12 levels did not show any difference between the CCHF and HC groups and among the severe, non-severe and HC groups. IL-10 and ET-1 levels were significantly higher in the severe group when compared to the non-severe group and the HC group. Moreover, IL-10 and ET-1 levels were significantly higher in the non-severe group when compared to the HC group. In terms of IL-6 and TNF-α levels, there was no difference between the severe and non-severe groups while the said levels were significantly higher in the severe group when compared to the HC group. The results of the present study showing significantly higher IL-10 and ET-1 levels in the severe group suggest that Th2-mediated humoral immunity is more effective in the pathogenesis and severity of CCHF in children.

RESUMO

PURPOSE: The aim of this study was to assess the role of ABO blood groups in predicting disease severity and bleeding potential in children with Crimean-Congo hemorrhagic fever (CCHF). METHODS: One hundred fifty-one hospitalized patients with CCHF were enrolled in this retrospective study. The patients were divided according to O- and non-O- (A, B and AB) blood groups (n=91 and n=60, respectively). They were also classified into two groups (severe and non-severe) based on disease severity (n=29 and n=122, respectively). Demographic characteristics, clinical findings, and hematologic and biochemical parameters of all patients were recorded on admission and discharge. RESULTS: Although, in all cases, compared to the non-O blood group, the ratio of the blood group O was considerably higher (60% vs. 40%) and similarly so in severe cases (58.6% vs. 41.4%), this difference was not statistically significant (p>0.05). The aPTT at discharge and fever duration of the O-blood group were significantly higher than those of the non-O-blood group (p=0.042, p=0.034, respectively). The factor VIII level of the O-blood group was significantly lower than that of the non-O-blood group (p=0.040). Although the ratios of bleeding and severity were higher in the O-blood group compared to the other group, statistical significance was not reached (p>0.05). CONCLUSIONS: Consideration of the ABO blood group is important during diagnostic follow-up to assess the severity of CCHF. In clinical practice, pediatric CCHF patients with the O blood group need to be followed closely for tendency to bleed.

RESUMO

OBJECTIVES: We investigated the effects of percutaneous mitral balloon valvuloplasty (PMBV) on right ventricular function in the long term using tissue Doppler imaging. STUDY DESIGN: Twenty-seven patients who underwent successful PMBV were enrolled in the study. Echocardiographic examination, including color tissue Doppler imaging, was done from the lateral tricuspid annulus 24 hours before the intervention, and the examination was repeated 24 hours and 6 months after the intervention. RESULTS: At 24 hours after the intervention, S wave velocity and A' wave velocity were seen to have increased significantly (9.52±1.85 cm/s vs. 10.92±1.20 cm/s, p=0.012; -10.44±2.64 cm/s vs. -11.73±2.05 cm/s, p=0.029, respectively). E' wave velocity and E'/A' ratio did not change significantly (p>0.05 for both). In the late period, S wave velocity was similar to the value in the early period and significantly higher than the basal level (9.52±1.85 cm/s vs. 10.69±1.72 cm/s, p=0.023). However, A' wave velocity in the late period was decreased compared to the early period and was not different from the basal level (-10.44±2.64 cm/s vs. -10.74±2.63 cm/s, p>0.05). The increase in E' wave velocity in the late period when compared to the basal level was found to be statistically significant (-7.85±1.54 cm/s vs. -9.21±1.81 cm/s, p=0.046). CONCLUSION: Right ventricular systolic function improved in the early period, and this improvement was seen to continue in the late period of PMBV. Diastolic function did not improve in the early period, but did improve in the late period. Right atrium systolic function improved in the early period; however, in the late period, levels were similar to the basal levels.

RESUMO

BACKGROUND: There are no definite data about the atrial electromechanical coupling times (AEMCT) in patients with end stage renal failure (ESRF). The aim of this study was to investigate the AEMCT in ESRF patients without hypertension (HT) and diabetes mellitus. METHODS: The study population consisted of 47 normotensive, nondiabetic ESRF patients and 41 healthy age/gender-matched control subjects. The time intervals from the onset of P-wave on the surface electrocardiogram to the beginning of late diastolic A-wave (PA) were obtained from the lateral mitral annulus (PA-lateral, maximum AEMCT), septal annulus (PA-septal), and tricuspid lateral annulus (PA-tricuspid). Time intervals were corrected according to the heart rate. The difference between PA-septal and PA-tricuspid (right AEMCT), PA-lateral and PA-septal (left AEMCT), and PA-lateral and PA-tricuspid (inter AEMCT) were calculated. Corrected time intervals were used for calculations. RESULTS: Groups were similar for age (52 ± 12.3 vs. 49.9 ± 6 years, P > 0.05) and gender. Maximum (61 ± 20 vs. 47 ± 13 ms; P < 0.001) AEMCT was significantly higher in the patients compared with the control group, but septal and tricuspid EMCT were not different (P > 0.05). Both inter-atrial (37 ± 21 vs. 24 ± 16 ms, P = 0.002) and left atrial (25 ± 18 vs. 12 ± 9 ms; P < 0.001) EMCT were significantly higher in patients when compared with the controls but intra-right atrial EMCT was not different. CONCLUSIONS: Atrial conduction parameters such as maximal EMCT, left atrial, and inter-atrial EMCTs were prolonged in ESRF patients. This prolongation is seen in ESRF patients even in the absence of factors that affect atrial coupling, such as HT.

RESUMO

OBJECTIVE: There is no study about hypertensive response to exercise (HRE), which is a marker of unborn hypertension (HT), and red cell distribution width (RDW) association, in diabetic normotensive patients. So, we aimed to investigate any correlation among RDW and HRE in normotensive type 2 diabetic patients. METHODS: Consecutive type 2 diabetic patients without history of HT and with normal blood pressure (BP) on ambulatory BP monitoring were included to the study. We divided the patients into two groups depending on their peak systolic BP on exercise; HRE (Group 1) or normal response to exercise (Group 2). RESULTS: Data of 75 diabetic patients (51.9 ± 9.7) were analyzed (31 male (48%)). Their mean RDW was 13.11 ± 0.46. Patients with HRE were significantly older than patients without HRE. Smoking was more frequent in Group 2. Gender distribution and body mass index were similar between the groups. Else hemoglobin, hematocrit, red blood cell count and RDW values were not significantly different. Office systolic BP and diastolic BP, daytime and 24-h systolic BP were significantly higher in Group 1 but heart rate was similar between the groups. CONCLUSIONS: This study revealed that RDW do not differ between diabetic normotensive patients with HRE or not.

RESUMO

OBJECTIVE: We aimed to assess the association between resting heart rate (RHR) and severe infection in children with Crimean-Congo hemorrhagic fever (CCHF). METHODS: In all, 121 patients under 18 years of age with a laboratory-confirmed diagnosis of CCHF were enrolled in the study. Patients were classified into two groups based on disease severity (severe group and nonsevere group). RHR was measured by electrocardiography (ECG) on admission. Maximum P-wave duration (Pmax), P-wave dispersion (Pd), QRS duration, corrected QT interval, and QT dispersion were also measured. RESULTS: Mean age was 11.4±3.9 years and 84 patients were male. Twenty-six patients were classified as severe. Patients in this group had a higher RHR (103.6±10.4 vs. 80.5±8.1, p=0.001) than those with nonsevere disease. There was no difference in Pmax, Pd, QRS duration, QTcmax, or QTc dispersion. The optimal cutoff value of RHR to predict disease severity was>96 beats per minute (bpm), with 70.6% sensitivity and 50.1% specificity. Bleeding, thrombocytopenia (≤80×10(9)/L), elevated aspartate transaminase (AST) (>208 IU/L), elevated alanine transaminase (ALT) (>87 IU/L), elevated lactate dehydrogenase (LDH) (>566 IU/L), long activated partial thromboplastin time (aPTT) (>42 s), and increased hospitalization days were more frequent in patients with RHR >96 bpm. Multivariate logistic regression analysis revealed low platelet count (<80×10(9)/L), long aPTT (>42 s), high LDH (>566 IU/L), and elevated RHR (>96 bpm) as independent risk factors for severe disease. CONCLUSIONS: We conclude that elevated RHR was significantly associated with severe disease in children with CCHF, thus offering the potential to identify patients with increased risk.

RESUMO

INTRODUCTION: Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease with a high mortality rate. In clinical practice, we observed bradycardia in some pediatric patients with CCHF during the clinical course. So we aimed to report CCHF cases that presented bradycardia during the clinical course and the relation of bradycardia with the clinical findings and ribavirin therapy. METHODS: Charts of all hospitalized pediatric CCHF patients were reviewed with respect to age, sex, history of tick bite or history of removing a tick, other risk factors for CCHF transmission, and interval between the tick bite and the onset of symptoms. Outcomes and clinical and laboratory findings and medications were recorded for each patient. We searched the patient records for information regarding the existence of bradycardia. Bradycardia was accepted as the heart rate 2 standard deviations (SD) lower than the suspected heart rate based on age. RESULTS: Fifty-two patients (mean age 11.2 ± 4.4 years, 31 female) were enrolled into the study. Bradycardia was seen in seven patients. Six patients with bradycardia were male and only one was female, and the mean age was 13.1 ± 1.6 years. It was observed that male gender is frequent among patients with bradycardia, as compared with those without bradycardia (p=0.01). Bleeding was found to be more frequent in patients with bradycardia (p=0.02). There were significant differences between the bradycardia and nonbradycardia groups with regard to the requirements for fresh frozen plasma transfusion, the number of platelet suspension given, requirement for intravenous immune globulin (IVIG) and in the days of stay in hospital (p=0.01, p=0.03, p=0.03, p=0.04, respectively). CONCLUSION: Reversible bradycardia might be seen in the clinical course of pediatric CCHF patients, and the clinicians must be aware of this finding. The possibility that ribavirin may potentiate bradycardia cannot be assessed without a placebo-control study. So further studies may help to reveal the cause of the bradycardia, the disease itself, or the ribavirin therapy. Hence this study supports the need for a randomized, placebo-controlled study to assess intravenous ribavirin in treating CCHF and to support approval of the drug.

RESUMO

AIM: Diastolic dysfunction (DD) is common in hemodialysis (HD) patients. Because diabetes mellitus (DM) and hypertension (HT) are also common in this patient group, the exact reason for DD in HD patients is not clear. The present study evaluated left ventricular (LV) diastolic function in HD patients without DM and HT. METHODS: Fifty patients on HD and 34 age-matched and sex-matched healthy control individuals were enrolled. Echocardiography was performed in all participants. LV systolic and diastolic functions were evaluated by B-mode echocardiography, pulsed wave, and tissue Doppler imaging. The HD patients were divided into two groups according to the presence or absence of left ventricular hypertrophy (LVH) in echocardiography. RESULTS: LV dimensions and systolic function were within normal limits and similar between groups. However, the HD patients had significantly worse diastolic function (E/A: 0.78 ± 0.26 vs. 1.19 ± 0.28, P < 0.001, e'/a' septal: 0.77 ± 0.36 vs. 1.04 ± 0.21, P < 0.001) and increased filling pressure (E/e': 8.55 ± 3.2 vs. 5.79 ± 1.93, P < 0.001). Thirty-one (62%) patients had LVH, whereas 19 (38%) patients did not have LVH. LV systolic and diastolic functions were similar in HD patients with and without LVH. Seventeen (55%) hypertrophies were concentric and 14 (45%) were eccentric. Diastolic functions were similar in patients with either concentric or eccentric hypertrophy. CONCLUSION: Diastolic function is impaired in HD patients even in the absence of diseases that can cause DD such as HT and DM.

RESUMO

OBJECTIVE: The aim of this retrospective multicenter study was to investigate the clinical manifestations, microbiological profile, echocardiographic findings and management strategies of infective endocarditis (IE) in Turkey. METHODS: The study population consisted of 248 Turkish patients with IE treated at 13 major hospitals in Turkey from 2005 to 2012 retrospectively. All hospitals are tertiary referral centers, which receive patients from surrounding hospitals. Data were collected from the medical files of all patients hospitalized with IE diagnosed according to modified Duke Criteria. RESULTS: One hundred thirty seven of the patients were males. Native valves were involved in 158 patients while in 75 participants there was prosthetic valve endocarditis. Vegetations were detected in 223 patients (89%) and 52 patients had multiple vegetations. Mitral valve was the most common site of vegetation (43%). The most common valvular pathology was mitral regurgitation. The most common predisposing factor was rheumatic valvular disease (28%). Positive culture rate was 65%. Staphylococci were the most frequent causative microorganisms isolated (29%) followed by enterococci (11%). In-hospital mortality rate was 33%. CONCLUSIONS: Compared to IE in developed countries younger age, higher prevalence of rheumatic heart disease, more frequent enterococci infection and higher rates of culture negativity were other important aspects of IE epidemiology in Turkey.

RESUMO

OBJECTIVES: There is no data about the incidence, progress and prognosis of Takotsubo Cardiomyopathy (TC) from Turkey. This study aimed to search for the progress and short-term prognosis of TC patients and to increase the familiarity and awareness for TC in Turkey. STUDY DESIGN: We included 6 patients who were referred to our center with ST elevation myocardial infarction and diagnosed as TC according to the Mayo Clinic diagnostic criteria. RESULTS: Our patients' median age was 46 years (range 17 to 64 years) and 3 of them were males. Triggering factors included emotional stress (3 patients) and physical stress (3 patients). Median troponin I level was 1.65 ng/ml (0.48-2.20), excluding the patients who underwent cardiopulmonary resuscitation. ST elevation in precordial leads was observed on the ECG of 4 patients and in inferior leads on ECG of 2 patients. Five patients' coronary arteries were normal and were diagnosed as typical, but 1 patient had non-critical stenosis on the coronary arteries and was diagnosed with reverse TC. Four patients were discharged without any complications but 2 presented with sudden cardiac death. CONCLUSION: This study presented the first data about TC in Turkey while attempting to increase awareness about the disease. Emergent ventricle evaluation by ventriculography or echocardiography is recommended for acute coronary syndrome patients with non-critical stenosis for the differential diagnosis.

RESUMO

Recovery of the ventricular function in a patient with cardiomyopathy is very rare. Autoimmune polyendocrine syndrome is also very rare. We herein report a case of reversed cardiomyopathy associated with autoimmune polyendocrine syndrome type II (Schmidt's syndrome) composed of Addison's disease, vitiligo and Hashimoto's thyroiditis. The ventricular function and size were reversed following the administration of suitable hormone replacement therapy for polyendocrine syndrome.
