Role of Serial Transverse Enteroplasty in the Management of Adult-Type Short Bowel Syndrome: Experience from a Single Tertiary Referral Hospital in Turkey.

BACKGROUND: There is little knowledge with regard to the management of intestinal failure in countries where home care services and dedicated intestinal rehabilitation centers are limited. This study presents a single-center experience of treating adult-type short bowel syndrome (SBS) with serial transverse enteroplasty (STEP). METHODS: Medical records were retrospectively reviewed from November 2009 to April 2018 on patients with adult-type SBS. All patients underwent STEP, and a representative quota sample of control patients treated with conventional measures were included. Clinico-demographic characteristics including baseline and post-treatment information about the orientation of bowel alignment and nutritional status were evaluated. RESULTS: The mean patient age was 51.1 ± 16.2 in the STEP group and 57.6 ± 12.7 in the control group (P = .304). The median small bowel length was 60 cm (interquartile range (IQR): 40-90) in the STEP group (before the lengthening) and 90 cm (IQR: 70-100) in the control (at the initiation of intestinal rehabilitation) (P = .035). Durations of median follow-up were 18 months (IQR: 14-58) and 10 months (IQR: 3-14), respectively (P = .019). In the STEP group, the mean increase in bowel length after STEP was 37.3 ± 11.6 cm, and at their follow-up 7 patients (64%) had successfully progressed to enteral autonomy. In the control group, only 3 patients (27%) were successful. Mean time to wean parenteral nutrition was 45 ± 54 days, and the mean increase in enteral calorie intake was 1.79 ± 1.60-fold after lengthening in the STEP group. CONCLUSIONS: STEP is an easy-to-perform procedure in the surgical rehabilitation of adult-type SBS. When performed simultaneously with reconnection surgery, it may offer a cost-effective and comprehensive solution to the treatment strategy in middle income settings.

The effect of global longitudinal strain on impaired six-minute walk test performance in patients with sarcoidosis.

BACKGROUND: Sarcoidosis is a multisystem and granulomatous disease associated with impaired functional capacity as a result of pulmonary and cardiac involvement. Factors adversely effecting functional capacity in patients with sarcoidosis have not been systematically assessed including myocardial strain imaging on echocardiography which enable to diagnose subclinical cardiac dysfunction. We aimed to evaluate the effect of left and right ventricular global longitudinal strain (GLS) on submaximal exercise capacity in patients with sarcoidosis who do not have clinically manifest cardiac involvement. METHODS: Extracardiac biopsy proven 56 patients with sarcoidosis and 26 controls were included consecutively. Submaximal exercise capacity of the subjects was assessed with six-minute walk test (6 MWT). Pulmonary function tests and standard transthoracic and two-dimensional speckle tracking echocardiography were performed to the all subjects. Linear regression analysis was performed to find independent predictors of 6 MWT. RESULTS: Fifty-six patients (18% male) with a mean age of 52.5 ± 10.7 years were included. Patients with sarcoidosis had low 6 MWT performance and higher New York Heart Association classes and NT-proBNP levels. There were no significant differences between controls and patients with sarcoidosis in parameters of pulmonary function test. Biventricular GLS levels and biatrial reservoir and conduit function values were lower and systolic pulmonary artery pressure (SPAP) was significantly higher in patients with sarcoidosis as compared with controls. Older age and higher SPAP were found as independent predictors of poor 6 MWT performance. CONCLUSION: Although biventricular GLS levels were lower in the patients with sarcoidosis, only age and SPAP elevations were independent predictors of the submaximal exercise capacity.

The anatomical relationship between the axillary artery and vein investigated by radial coronary angiography.

AIMS: To reduce the risk of inadvertent arterial puncture and bleeding, we aimed to define a safe puncture site by demonstrating the relation of the axillary artery and vein. METHODS: The anatomical course and relation as well as crossover sites of the axillary artery and vein, the presence of small arterial bridges over the axillary vein, and validation of commonly preferred axillary venous puncture sites were determined by simultaneous ipsilateral venography in patients (n  =  111; 80 men, age 60 ± 10 years) who underwent coronary angiography by radial artery access. RESULTS: The axillary vein was detected at the first costa-clavicular intersection in 62% and at the second anterior and third posterior costal intersection in 60% of the patients. Small arterial bridges over the axillary vein were observed in 77% of the patients and more frequently in females and body mass index ≥25 kg/m2 (P  =  0.034 and P  =  0.03, respectively). The axillary artery crossed the vein in 24% of the patients and almost always within the region close to the first costa-clavicular intersection site. CONCLUSION: Our study demonstrated a high crossover rate (24%) of axillary artery and vein and a high degree of variation in the course of axillary vein. Small arterial bridges over the axillary vein were observed in 77% of the patients.

[Approach to syncope in the elderly]. / Yaslilarda senkop'a yaklasim.

Elderly syncope currently accounts a substantial number of emergency admissions. Unfortunately, in elderly syncope we are faced with major difficulties while providing diagnostic and therapeutic decisions. It is quite necessary to distinguish between syncope and non-syncopal causes which create further difficulties during diagnostic work-up because of co-morbid conditions and poly-pharmacy used by the elderly. The present article aims to describe causes of elderly syncope and its differential diagnosis as well as tips and tricks during diagnostic process.

Horizontal ECG in acute anterolateral myocardial infarction.

BACKGROUND: The present study aims to compare the amount of ST segment changes recorded by horizontal electrocardiography (hECG) with standard ECG (sECG) in patients with acute anterior and/or lateral ST segment elevation myocardial infarction (STEMI). METHODS: Consecutive eligible patients (n = 58) who were diagnosed with acute anterior and/or lateral STEMI were included in the study. After recording simultaneous sECG and hECG by placing precordial leads (V3-6) horizontally on the left 4th intercostal space, ST segment changes were compared. RESULTS: The mean ST segment changes (mV) on hECG were significantly higher than sECG in V4 (0.27 ± 0.2 vs. 0.21 ± 0.21, p = 0.001), V5 (0.21 ± 0.17 vs. 0.12 ± 0.16, p < 0.001) and V6 (0.09 ± 0.1 vs. 0.04 ± 0.12, p < 0.001), respectively. When hECG and sECG were compared in patients with BMI < 30 kg/m(2), mean ST segment changes (mV) on hECG were significantly higher than sECG in V4 (0.29 ± 0.21 vs. 0.21 ± 0.24, p = 0.004), V5 (0.22 ± 0.19 vs. 0.13 ± 0.17, p < 0.001) and V6 (0.11 ± 0.11 vs. 0.04 ± 0.11, p < 0.001), respectively. CONCLUSIONS: Mean ST segment changes in patients with anterior and/or lateral STEMI were significantly higher and easily detectable on hECG compared with sECG. We suggest that hECG be used in conjunction with sECG to diagnose anterior and lateral wall STEMI in cases of diagnostic doubt.

Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio are Predictors of Heart Failure / Relações Neutrófilo-Linfócito e Plaqueta-Linfócito Como Preditores de Insuficiência Cardíaca

Abstract Background: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are inflammatory markers used as prognostic factors in various diseases. The aims of this study were to compare the PLR and the NLR of heart failure (HF) patients with those of age-sex matched controls, to evaluate the predictive value of those markers in detecting HF, and to demonstrate the effect of NLR and PLR on mortality in HF patients during follow-up. Methods: This study included 56 HF patients and 40 controls without HF. All subjects underwent transthoracic echocardiography to evaluate cardiac functions. The NLR and the PLR were calculated as the ratio of neutrophil count to lymphocyte count and as the ratio of platelet count to lymphocyte count, respectively. All HF patients were followed after their discharge from the hospital to evaluate mortality, cerebrovascular events, and re-hospitalization. Results: The NLR and the PLR of HF patients were significantly higher compared to those of the controls (p < 0.01). There was an inverse correlation between the NLR and the left ventricular ejection fraction of the study population (r: -0.409, p < 0.001). The best cut-off value of NLR to predict HF was 3.0, with 86.3% sensitivity and 77.5% specificity, and the best cut-off value of PLR to predict HF was 137.3, with 70% sensitivity and 60% specificity. Only NLR was an independent predictor of mortality in HF patients. A cut-off value of 5.1 for NLR can predict death in HF patients with 75% sensitivity and 62% specificity during a 12.8-month follow-up period on average. Conclusion: NLR and PLR were higher in HF patients than in age-sex matched controls. However, NLR and PLR were not sufficient to establish a diagnosis of HF. NLR can be used to predict mortality during the follow-up of HF patients.

Resumo Fundamentos: A obesidade mórbida está diretamente relacionada à deterioração da capacidade cardiorrespiratória, incluindo alterações na modulação autonômica cardiovascular. Objetivo: Este estudo teve por objetivo avaliar a função autonômica cardiovascular de obesos mórbidos. Métodos: Estudo transversal, incluindo dois grupos, Grupo I, composto por 50 obesos mórbidos, e Grupo II, por 30 indivíduos não obesos. A função autonômica foi avaliada pela variabilidade da frequência cardíaca no domínio do tempo [desvio padrão de todos os intervalos R-R normais (SDNN); desvio-padrão de todos os intervalos R-R normais (SDNN); raiz quadrada das médias quadráticas das diferenças dos intervalos R-R sucessivos (RMSSD); e o percentual de diferenças de intervalo intervalos R-R sucessivos maior que 50 milissegundos (pNN50)] em comparação ao adjacente, e no domínio da frequência (HF, do inglês, “high frequency”, e LF, do inglês, “low frequency”: integração da função da densidade espectral de potência para as bandas de alta e baixa frequência, respectivamente). Os grupos foram comparados pelo teste t de Student, considerando-se um nível de significância de 5%. Resultados: Quando comparados aos controles, os indivíduos obesos apresentaram valores menores de SDNN (40,0 ± 18,0 ms vs. 70,0 ± 27,8 ms; p = 0,0004), RMSSD (23,7 ± 13,0 ms vs. 40,3 ± 22,4 ms; p = 0,0030), pNN50 (14,8 ± 10,4 % vs. 25,9 ± 7,2%; p = 0,0061) e HF (30,0 ± 17,5 Hz vs. 51,7 ± 25,5 Hz; p = 0,0023). A relação LF/HF média foi maior no Grupo I (5,0 ± 2,8 vs. 1,0 ± 0,9; p = 0,0189), refletindo alteração no equilíbrio simpato-vagal. Não houve diferença estatística entre os grupos I e II com relação ao índice LF (50,1 ± 30,2 Hz vs. 40,9 ± 23,9 Hz; p = 0,9013). Conclusão: obesos mórbidos apresentam aumento de atividade simpática e redução da atividade parassimpática, caracterizando uma disfunção autonômica cardiovascular.

Arrhythmogenic epilepsy and pacing need: A matter of controversy.

There is increasing awareness among the cardiology community regarding ictal bradyarrhythmias as a cause of loss of consciousness. A high degree of suspicion is necessary when diagnosing ictal bradyarrhythmias, and delay in diagnosing this condition may lead to morbidity associated with falls and trauma. Ictal bradyarrhythmias have also been suggested to be associated with sudden unexplained death in epilepsy, although evidence related to this association is limited. There is no guideline-directed therapy for symptomatic ictal bradyarrhythmias due to a lack of randomized, controlled trials. Cardiac pacemaker therapy is commonly used for these patients; however, currently, there is no universal agreement on the pacing indications for these patients. In this review, we focus on the pathophysiology and clinical presentation of ictal bradyarrhythmias and then discuss the pacing need based on the available literature data.

Protective effects of amifostine on ischemia-reperfusion injury of rat kidneys.

OBJECTIVES: Amifostine is a drug which can eliminate free oxygen radicals that appear in the body after radiation or chemotherapeutic agent exposure. It is used to decrease the renal toxicity of cisplatin. The aim of this study was to determine the role of amifostine in warm ischemia kidney model for prevention of ischemia/reperfusion injury and also to find out the mechanism for prevention from ischemia/reperfusion injury if such an effect does exist. MATERIALS AND METHODS: Adult female rats (n = 40) that used in our study were divided into three groups. Group 1: Control (n = 8), group 2: Ischemia-control (n = 16), group 3: Amifostine treated (n = 16). The effect of amifostine on ischemia/reperfusion injury investigated in rat kidneys. RESULTS: At the 7(th) day, blood urea nitrogen level was statistically significantly higher in ischemia-control group than all groups (P = 0.001) and mean serum creatinine levels were found to be the highest in ischemia-control group (P = 0.091). Mean malondialdehyde levels in left kidneys removed on the 7(th) day were not significantly different (P = 0.105) at all three groups. Between ischemia-control group and amifostine group, there was a significant difference in reduced glutathione (GSH) levels (P = 0.001). In amifostine group, grade 4 necrosis was not detected neither on 7(th) day nor day 0. CONCLUSION: Amifostine could decrease the degree and severity of necrosis after reperfusion. Amifostine could not prevent membrane lipid peroxidation caused by superoxide anion radicals in kidney but they could protect tissues from the harmful effects of ischemia/reperfusion injury by increasing the level of reduced GSH which is a well-known oxygen radical eliminator.

Acute effect of zoledronic acid infusion on atrial fibrillation development in patients with osteoporosis.

OBJECTIVE: There is ongoing controversy related to the relationship between bisphosphonates and atrial fibrillation (AF). Our aim in this study was to evaluate the potential acute effect of zoledronic acid (ZA) infusion on AF development by using 24-hour Holter recordings. METHODS: The study was designed to be a self-controlled case series study, and 33 consecutive patients with osteoporosis (29 females, age: 62.3±9.0 years) who were scheduled to receive ZA infusion constituted the study population. Patients underwent 24-hour Holter rhythm recordings at two different times; the first one was 48 hours before the planned ZA infusion, and the second one was on the morning of the infusion day. Heart rate, frequency and type of arrhythmias, as well as heart rate variability (HRV) from the two recordings were compared. RESULTS: There were no episodes of AF greater than 30 sec in any of the 24-hour Holter recordings obtained before and on the day of drug infusion. Holter recordings before drug infusion showed that only 1 patient had an atrial run of 3 beats long. Holter recordings obtained on the day of drug infusion revealed that 5 patients (15.2%) had atrial runs with lengths ranging between 3 and 12 beats (p=0.046). Regarding HRV variables, SDANN values were found to be significantly depressed on the day of ZA infusion (113.6±26.9 vs. 98.2±29.9, p=0.007). CONCLUSION: None of the patients developed AF during or early after ZA infusion. However, there was an increase in atrial ectopy in some patients, which might be due to alterations in cardiac autonomic activity.

A rare complication of gastric bypass (weight loss) surgery: nesidioblastosis.

Here, we present the case of a 31-year-old woman patient who underwent distal pancreatectomy with the history of gastric bypass surgery for obesity. The final histopathological diagnosis of the lesion was nesidioblastosis. Nesidioblastosis is the most common cause of organic persistent hyperinsulinemic hypoglycemia in newborns; however, it is rare in adults. In adults, it is difficult to diagnose nesidioblastosis with only clinical findings. The definitive diagnosis of the disease depends on the histopathological examination of pancreatic tissue and the exclusion of insulinoma.

Asymptomatic ST segment elevation in the recovery phase of the exercise stress test due to slow coronary flow.

Exercise-induced ST segment elevation without Q wave formation is rarely observed. Frequent causes are significant coronary stenosis, myocardial bridge and coronary vasospasm. Both exercise-induced ST segment elevation due to slow coronary flow and ST segment elevation in the recovery phase of the exercise stress test are very rare. We present a 49-year-old man with asymptomatic inferolateral ST segment elevation in the recovery phase of the exercise stress test due to slow coronary flow, which has not been reported previously. The learning points of the present paper are as follows: a) although significant coronary stenosis, myocardial bridge and coronary vasospasm are frequent causes of exercise-induced ST segment elevation, slow coronary flow might also cause it; b) one should keep in mind that ST segment elevation might also occur in the recovery phase; and c) ST segment elevation might be asymptomatic, as in the present case.

Increase in QRS amplitudes is better than N-terminal pro-B-type natriuretic peptide to predict clinical improvement in decompensated heart failure.

BACKGROUND: We aimed to investigate the correlation between ECG QRS voltage changes, N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and clinical improvement in decompensated heart failure (DHF). METHODS AND RESULTS: DHF patients (n=56) with a mean age of 67.5±12.6 years showed limb QRS amplitude increase and NT-proBNP level decrease with clinical improvement (p<0.001). Significant correlation was found between percent changes (Δ%) in body weight and Δ% in QRS voltages of aVR, aVF, DII, ΣQRSI+II and ΣQRS (all limb-leads) (r = -0.40; r = -0.35; r = -0.32; r = -0.30; r = -0.30 respectively, p<0.05). No correlation was found between Δ% in NT-proBNP and body weight (r = -0.23, p=0.09). Δ% NT-proBNP was correlated with Δ% QRS voltage only in aVR (r = -0.312, p=0.019). In ROC analysis, ≥0.5 mm increase in aVR QRS voltage was found to predict ≥5 kg weight loss with a sensitivity of 74% and specificity of 62% (p=0.013, AUC: 0.699). CONCLUSIONS: Increase in QRS voltages especially in aVR was found to be more sensitive than NT-proBNP to predict clinical improvement in DHF.

Successful treatment of myocardial bridge with alcohol septal ablation in hypertrophic obstructive cardiomyopathy.

Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by left ventricular hypertrophy of various morphologies, with variety of clinical manifestations and hemodynamic dysfunctions. Myocardial bridge (MB) is frequently seen in HOCM patients and the decrease of flow in the coronary artery segment going intramurally through the myocardium beneath a muscle bridge is also associated with angina, myocardial ischemia, arrhythmia, and sudden death in these patients. We present here a rare case of successful treatment of MB with alcohol septal ablation in hypertrophic cardiomyopathy which has not been reported previously.
