The effect of oral supplementation with a combination of beta-hydroxy-beta-methylbutyrate, arginine and glutamine on wound healing: a retrospective analysis of diabetic haemodialysis patients.

BackgroundDiabetes is an important reason for end-stage renal failure and diabetic foot wounds worsen the life qualities of these patients. Protein and amino acid support accelerates the wound healing. The purpose of this retrospective study is to examine the effect of beta-hydroxy-beta-methylbutyrate, arginine and glutamine (Abound®) supplementation on the wound healing.MethodsA total of 11 diabetic dialysis patients were included in this retrospective study aiming to evaluate the effect of the diet support with beta-hydroxy-beta-methylbutyrate, arginine and glutamine on wound healing in diabetic dialysis patients. Pre-treatment and post-treatment wound depth and wound appearance were scored in accordance with the “Bates-Jensen” wound assessment tool. The results of 4-week treatment with beta-hydroxy-beta-methylbutyrate, arginine and glutamine (Abound®) support were evaluated in terms of wound healing.ResultsThe mean age of patients was 66 (SD: 10, range: 51-81) and 9 (81.8%) of them were males. After the 4-week treatment, in accordance with the Bates-Jensen scoring, healing was observed on the wound depth score of 7(63.6%) patients and on wound appearance score of 8(72.7%) patients out of 11. While the wound depth score of 4(36.4%) cases and wound appearance score of 3(27.3%) cases remained the same, no deterioration was observed on any cases throughout the follow-up period.ConclusionIn conclusion, our findings revealed that Abound treatment makes a positive contribution to the wound healing in diabetic dialysis patients.

Slow ventricular response atrial fibrillation related to mad honey poisoning.

Mad honey poisoning which is induced by Grayanotoxin (Andromedotoxin), is also known to have adverse effects in the cardiovascular system leading to different clinical entities. This toxin is produced by a member of the Rhododendron genus of plants of two R. Luteum and R. Panticum. In this article, we presented a case of slow ventricular response atrial fibrillation complaints with nausea, vomiting, dizziness and chest pain about an hour after eating honey produced in the Black Sea Region.

Allopurinol-induced DRESS syndrome.

A 70-year-old man was admitted to our clinic with complaints of fever, jaundice, dyspnea, and generalized rash after 3 months of allopurinol treatment for gout. On physical examination, he was found to have fever (38.5°C), jaundice, and generalized maculopapular rash. Leukocytosis, eosinophilia, elevation of liver enzymes, and hyperbilirubinemia were detected in his blood analysis. Skin biopsy was consistent with drug-induced hypersensitivity. He was diagnosed as Drug Rash with Eosinophilia and Systemic Symptoms (DRESS). Allopurinol treatment was stopped and steroid treatment was launched. At day 24 of admission, the patient died because of multiple organ failure.

The relationship between epicardial fat tissue thickness and visceral adipose tissue in lean patients with polycystic ovary syndrome

BackgroundPolycystic ovary syndrome (PCOS) is related to metabolic syndrome, insulin resistance, and cardiovascular metabolic syndromes. This is particularly true for individuals with central and abdominal obesity because visceral abdominal adipose tissue (VAAT) and epicardial adipose tissue (EAT) produce a large number of proinflammatory and proatherogenic cytokines. The present study aimed to determine whether there are changes in VAAT and EAT levels which were considered as indirect predictors for subclinical atherosclerosis in lean patients with PCOS.MethodsThe clinical and demographic characteristics of 35 patients with PCOS and 38 healthy control subjects were recorded for the present study. Additionally, the serum levels of various biochemical parameters were measured and EAT levels were assessed using 2D-transthoracic echocardiography.ResultsThere were no significant differences in mean age (p = 0.056) or mean body mass index (BMI) (p = 0.446) between the patient and control groups. However, the body fat percentage, waist-to-hip ratio, amount of abdominal subcutaneous adipose tissue, and VAAT thickness were higher in the PCOS patient group than in the control group. The amounts of EAT in the patient and control groups were similar (p = 0.384). EAT was correlated with BMI, fat mass, waist circumference, and hip circumference but not with any biochemical metabolic parameters including the homeostasis model assessment of insulin resistance index or the levels of triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein (HDL) cholesterol. However, there was a small positive correlation between the amounts of VAAT and EAT. VAAT was directly correlated with body fat parameters such as BMI, fat mass, and abdominal subcutaneous adipose thickness and inversely correlated with the HDL cholesterol level.ConclusionsThe present study found that increased abdominal adipose tissue in patients with PCOS was associated with atherosclerosis. Additionally, EAT may aid in the determination of the risk of atherosclerosis in patients with PCOS because it is easily measured.

Retrospective evaluation of patients at follow‑up with acute poisoning in Intensive Care Unit

OBJECTIVE Poisonings are among the major causes of emergency visits and intensive care hospitalizations. The aim of our study is to evaluate intoxicated patients at follow-up and treated in the Intensive Care Unit (ICU) in terms of demographic characteristics, type of poisonings and results of treatment. MATERIALS AND METHODS Patients at follow-up aged 17 or older admitted with intoxication to the ICU between January 1, 2009 and December 31, 2011 were included in the study. Age, gender, presenting symptoms, duration of hospitalization, type of poisoning, the way of poisoning, medical history, seasons, hospitalization costs, treatment and prognosis of the patients were analyzed. RESULTS Totally, 153 (8.9%) out of 1375 follow-up patients in the ICU had acute intoxication. The mean age of intoxicated patients was 29.4 ± 11, 68% of them were female, 78.4% of them were under 35 years old, and intoxication was most common in the 17-25 age group. 114 of them (94.1%) were suicidal. The most common cause of poisoning was drug-poisoning by 88.2%, and most common presenting symptoms were nausea and vomiting by 71.2%. Mean length of stay was 2.4 ± 1.6 days, and the average cost of hospitalization was 761 ± 884 Turkish Liras or 271 ± 315 USD. 5 patients (3.3%) were intubated because of respiratory failure. There was no mortal case. CONCLUSION Suicide attempts are prominent in acute poisoning, and the young female population is at higher risk. It was found that drugs, particularly antidepressants and antipsychotic agents were the most common cause of poisoning. The high cost of treatment of acute intoxication cases is a major cause of economic burden. Clinicians should be more careful when prescribing such drugs.

Nutritional status and laboratory parameters among internal medicine inpatients

BACKGROUND Malnutrition is a clinical state resulting in prolonged hospital stay, increase in severity of infections and poor wound healing. AIMS Our aim was to investigate the prevalence and etiologic factors of malnutrition in medical inpatients. STUDY DESIGN A total of 290 consecutively admitted internal medicine patients from February to May 2012 were included. On admission, demographic data, anthropometric measurements, laboratory parameters and nutritional screening test results were recorded. METHODS Nutritional risk score-2002 for patients under 65 years old, mini nutritional assessment for older patients and subjective global assessment (SGA) tests performed. Relation of demographic characteristics, laboratory parameters, weight and body mass index (BMI) with nutritional status were evaluated. RESULTS Mean age was 61±17 years; 145 patients were male. Among 160 patients<65 years old, 34 were in malnutrition (21%), 41 (26%) were under risk of malnutrition and 85 (53%) were normal. When they were divided into three groups according to SGA, we found significant difference in hemoglobin, low density lipoprotein (LDL), high density lipoprotein, cholesterol, triglyceride, albumin and protein, weight and BMI. Among 130 patients over 65 years old, 47 patients (37%) were in malnutrition, 41 (31%) were under risk of malnutrition and 42 (32%) were normal. There was significant difference in LDL, cholesterol, albumin, protein, weight and BMI between three groups; each 1 g/dl decrease in serum albumin and age older than 65 years old increased malnutrition risk 5.21 and 1.97 times, respectively. CONCLUSION Malnutrition risk is high among internal medicine inpatients and risk seems to be higher among older patients. Nutritional screening of geriatric patients, close follow-up and providing earlier health care would contribute rehabilitation of chronic diseases and decrease re-admissions.

Diagnosis of Vitamin B12 Deficiency in Patients With Myeloproliferative Disorders

Background Myeloproliferative disorders are characterized by proliferation of 1 or more lineage of hematologic cells. Rapid proliferation of cells may lead to depletion of vitamin B12, which may be falsely elevated by conventional assays in these disorders. We evaluated vitamin B12 status with conventional vitamin B12 assay and levels of serum methylmalonic acid (MMA), serum holotranscobalamin (holoTC), and plasma homocysteine in myeloproliferative disorders. Methods In 58 patients who had myeloproliferative disorders and normal serum creatinine levels, we measured levels of vitamin B12, MMA, holoTC, and homocysteine. Correlations were evaluated between these tests, with MMA as the reference standard for vitamin B12 deficiency. Results Prevalence of vitamin B12 deficiency was 69%, despite high serum vitamin B12 levels. Levels of holoTC of 40.6 pmol/L or less and homocysteine of greater than 14 mol/L were the best cutoff levels with sensitivity values of 75% and 70%, specificity values of 80% and 68%, and positive predictive values of 88% and 80%. Logistic regression showed that cutoff values of holoTC of 40.6 pmol/L or less and homocysteine of greater than 14 mol/L resulted in odds ratio 15.5 for low versus high holoTC, and odds ratio 5.4 for high versus low homocysteine, to confirm vitamin B12 deficiency. Conclusions Patients who had myeloproliferative disorders had a high prevalence of vitamin B12 deficiency, despite high serum vitamin B12 levels. Therefore, vitamin B12 status should be evaluated in patients with myeloproliferative disorders. Holotranscobalamin level may be the best initial test and may replace vitamin B12 assay to accompany MMA and homocysteine levels.

Agreement of serum potassium measured by blood gas and biochemistry analyzer in patients with moderate to severe hyperkalemia

PURPOSE Several studies investigated the agreement between central laboratory biochemistry analyzers and blood gas analyzers for potassium measurements. However, data are scarce when the potassium level is moderate to severely high. We aimed to evaluate the agreement between central laboratory biochemistry analyzers and blood gas analyzer in terms of serum potassium level measurement because differences in potassium at this level translate into very different clinical actions. BASIC PROCEDURES This was a retrospective medical record review study in which patients who presented to the emergency department and had serum potassium levels ≥6mmol/L were included. Patients who did not have simultaneous potassium measurement by blood gas analyzer were excluded. We included all patients meeting potassium criteria irrespective of their underlying disease or comorbidities. We evaluated agreement between the measurement methods with Pearson correlation, Bland-Altman plot, and Sign test. MAIN FINDINGS A total of 118 blood sample pairs were included. The mean serum potassium level measured by biochemistry analyzer was 6.78±0.79mmol/L, whereas it was 6.16±0.86mmol/L by blood gas analyzer (P<.001, Sign test). There was a strong correlation (P<.001, r=0.864) between the 2 methods, but agreement was relatively poor. Blood gas analyzer tended to measure potassium significantly lower than measured by biochemistry analyzer. The mean difference between the methods was 0.62±0.43mmol/L. PRINCIPAL CONCLUSIONS In patients with moderate to severe hyperkalemia, blood gas analyzer and biochemistry analyzer gives significantly different serum potassium results which may be clinically important.

Does Vitamin D Deficiency Effect Heart Rate Variability in Low Cardiovascular Risk Population

AIM: This study aimed to evaluate the cardiac autonomic dysfunction and the cardiac arrhythmia risk using heart rate variability parameters in subjects with vitamin D deficiency and low cardiovascular risk. MATERIAL AND METHODS: One hundred five consecutive individuals, 54 patients with low vitamin D status and 51 healthy controls were enrolled in this study. The overall cardiac autonomic tone was quantified by using various heart rate variability parameters included mean RR interval, mean Heart Rate, mean of standard deviations of intervals for 24 hours (SDNN), standard deviation of averages of intervals (SDANN), mean of standard deviation of intervals for 5 minutes (SDNNI), root mean square of difference of successive intervals (rMSSD) and the proportion of intervals differing more than 50 ms (pNN50) values. The 12-lead ECG was recorded from each participant, and QT intervals were measured. RESULTS: Baseline demographic profiles were similar between two groups. The heart rate variability parameters such as mean RR interval, mean HR, SDNN, SDANN, SDNNI, rMSSD and pNN50 (%) values were not significantly different in patients with low vitamin D status compared to control group. The electrocardiography analysis revealed only slight but significant prolongation of corrected QT (QTc) intervals in the control group. CONCLUSION: HRV variables were not significantly altered in patients with vitamin D deficiency in low cardiovascular risk profile group. Further studies evaluating these findings in other cohorts with high cardiovascular risk are required.

Severe Hypokalaemia, Hypertension, and Intestinal Perforation in Ectopic Adrenocorticotropic Hormone Syndrome.

Ectopic adrenocorticotropic hormone (ACTH) syndrome is a rare cause of the Cushings syndrome. The occurrence of the ectopic ACTH syndrome presenting with severe hypokalaemia, metabolic alkalosis, and hypertension has been highlighted in case reports. However, presentation with lower gastrointestinal perforation is not known. We report the case of a 70-year-old male patient with severe hypokalaemia, metabolic alkalosis, hypertension, and colonic perforation as manifestations of an ACTH-secreting small cell lung carcinoma. Ectopic ACTH syndrome should be kept in mind as a cause of hypokalaemia, hypertension, and intestinal perforation in patients with lung carcinoma.
