A comparison of four different HRQoL generic questionnaire in five different patient groups

Most of musculoskeletal diseases involve pain and reduced physical functioning. Recognition of the coexistence of more than one musculoskeletal disease is important because they are relatively common and has a substantial impact on health-related quality of life (HRQoL). Our aim was to compare the results of four generic QoL questionnaires—QoL-5, Nottingham Health Profile (NHP), Short Form (SF)-6D, and Visual Analogue Scale (VAS)—in five different patient groups. Two hundred and one patients representing five different disease groups (knee osteoarthritis, osteoporosis, back pain, rheumatoid arthritis and ankylosing spondylitis), randomly selected through the Ankara Numune Education and Research Hospital Physical Medicine and Rehabilitation Outpatient Clinic, were included in the study. Scores indicating low QoL for each of the five diseases compared are reported. Patients in each disease group stated high disability. No strong correlation between any of the scales could be determined, and NHP was identified as the only scale able to differentiate between the diseases. Many instruments are available for measuring HRQoL. The QoL-5, NHP, SF-6D, and VAS are four commonly used generic (i.e., not disease-specific) measures for quantifying HRQoL in patients with musculoskeletal disorders. Most studies have focused on only one musculoskeletal disease, but comorbidity of musculoskeletal disorders is common. We emphasize in this study the effect of multiple musculoskeletal diseases on HRQoL.     

Hepatic subcapsular steatosis as a complication associated with intraperitoneal insulin treatment in diabetic peritoneal dialysis patients.

OBJECTIVES: The aim of this study was to evaluate hepatic subcapsular steatosis (HSS) and its association with clinical parameters in nondiabetic continuous ambulatory peritoneal dialysis (CAPD) patients and in diabetic CAPD patients receiving intraperitoneal (IP) or subcutaneous (SC) insulin. DESIGN: Cross-sectional study. SETTING: A tertiary-care university hospital. PATIENTS: 28 CAPD patients (17 males and 11 females; mean age 53.5 +/- 14 years; mean CAPD duration 22.8 +/- 9 months) were included in the study. 14 patients had type II diabetes mellitus and 14 were nondiabetics. In the diabetic group, 8 patients were receiving IP insulin and 6 were receiving SC insulin. OUTCOME MEASURES: HSS was diagnosed on computed tomography without contrast administration. Other data collected were body mass index (BMI), weekly Kt/V, peritoneal equilibration test (PET) results, daily insulin dosage, duration of diabetes mellitus, duration of insulin treatment, dialysate glucose load, and serum findings for alanine aminotransferase, aspartate aminotransferase, albumin, and lipid profiles. RESULTS: HSS was detected in 5 of the 8 diabetics who were receiving IP insulin. None of the diabetics receiving SC insulin and none of the nondiabetic patients exhibited HSS. Daily insulin dosage [108 (95 - 108.5) vs 54 (36 - 72) U/day, p = 0.02], BMI [31 (30.5 - 36) vs 26.6 (26 - 30) kg/m2, p = 0.02], serum triglyceride level [194 (184 - 505) vs 69 (61 - 82) mg/dL, p = 0.04], and PET creatinine levels [D/P2 creat: 0.67 (0.54 - 0.74) vs 0.50 (0.50 - 0.56), p = 0.05; D/P4 creat: 0.75 (0.64 - 0.86) vs 0.60 (0.59 - 0.62), p = 0.02] were higher in diabetic patients receiving IP insulin who had HSS than in those who did not have HSS. PET glucose levels [D0/D2 glu: 0.40 (0.37 - 0.45) vs 0.50 (0.48 - 0.51), p = 0.03; D0/D4 glu: 0.36 (0.26 - 0.38) vs 0.44 (0.38 - 0.48), p = 0.04] were lower in diabetic patients receiving IP insulin who had HSS than in those who did not have HSS. CONCLUSIONS: Our results suggest that IP insulin plays a more important role in the pathogenesis of HSS than glucose levels in diabetic CAPD patients. They also indicate that HSS is associated with higher daily insulin requirement, obesity, hypertriglyceridemia, and high peritoneal transport rate in diabetic CAPD patients receiving IP insulin.     

Does a fibrin sheath formed around a catheter embolize upon removal of the catheter?

Sir, Central venous catheters (CVC) are commonly used in haemodialysispatients. Encasement of the catheter by a fibrin sleeve is awell known complication which can interfere with catheter functionand prevent effective haemodialysis [1]. These sleeves do notcome with the catheter upon removal, but remain in the vein.Although millions of CVC are inserted and removed every year,there are few clinical reports describing what happens to thesleeve remaining inside the venous lumen upon removal [2,3].We conducted a prospective study to assess whether fibrin sheathformed around a short-term haemodialysis catheter embolizes     

Abietic acid inhibits lipoxygenase activity.

In this study, it was shown that abietic acid, an abietane diterpenoid, inhibited soybean 5-lipoxygenase (linoleate: oxygen oxidoreductase, EC 1.13.11.12) and an IC(50) of 29.5 +/- 1.29 microM was determined. Since the lipoxygenase pathway leads to the biosynthesis of leukotrienes this result supports the view that abietic acid may be used in the treatment of allergic reactions.     

A family with IgA nephropathy and hereditary lymphoedema praecox

Immunoglobulin A (IgA) nephropathy is the most common primary glomerulonephritis worldwide. The pathogenesis is still unknown and treatment has not yet been established. Rarely it can be associated with other disorders. Its association with hereditary lymphoedema is not reported before. We report four patients, a 60-year-old father, his two sons and his daughter, with hereditary lymphoedema. The family had nine members and in four of them lymphoedema was evident. The other members had neither lymphoedema nor IgA nephropathy. This is the first report of IgA nephropathy in association with hereditary lymphoedema.     

Effects of glucose-insulin-potassium solution added to reperfusion treatment in acute myocardial infarction.

OBJECTIVE: Reperfusion treatment modalities used in the routine treatment protocols of acute myocardial infarction (AMI) were found to be ineffective in establishing the nutritional cellular reperfusion in the microvascular environment even they succeed to open the infarct related artery. Glucose-insulin-potassium (GIK) solution, which is presumed to stimulate the glycolytic pathway, is experimentally proven to be the most efficacious substrate for the preservation of energy production and therefore the myocardial viability, in the setting of acute ischemia. METHODS: We compared, 54 patients who suffered AMI and received GIK solution (300 g glucose+50 IU crystallized insulin+80 mEq potassium chloride in one liter solution) in addition to conventional treatment (GIK group) with 27 patients who were traditionally treated (control group) for in-hospital and early-term (1 month) cardiac morbidity. We also compared the two groups in terms of heart rate variability (HRV). RESULTS: Eight patients in the control group developed new-onset symptomatic congestive heart failure whereas only 5 patients in GIK group were found to have such a cardiac morbidity (p=0.01). Reduced HRV (<50 ms) was found in 3 patients of control group whereas no patient in GIK group had abnormal HRV (p=0.01). CONCLUSION: The GIK solution decreased the incidence of new-onset symptomatic congestive heart failure and low HRV after myocardial infarction. Larger multicenter trials need to resolve the questions on the efficiency of metabolic intervention with GIK solution in acute myocardial infarction.
