Validation of the Omron M6 (HEM-7001-E) upper arm blood pressure measuring device according to the International Protocol in elderly patients

OBJECTIVE: Despite the widespread use of automated self-measurement monitors, there is limited published evidence on their accuracy and reliability on different patient groups. The objective of this study was to evaluate the accuracy and reliability of the Omron M6 (HEM-7001-E) upper-arm blood pressure (BP) device against mercury sphygmomanometer on elderly patients according to the criteria of the International Protocol. DESIGNS AND METHODS: Thirty-three patients above 65 years of age, who were classified based on the BP categories of the International Protocol, were recruited for the study. BP measurements at the upper arm with the Omron M6 were compared with the results obtained by two trained observers using a mercury sphygmomanometer. Nine sequential BP measurements were taken. During the validation study, 99 measurements were obtained from 33 patients for comparison. The first phase was carried out on 15 patients and if the device passed this phase, 18 more patients were selected. RESULTS: Mean discrepancies and standard deviations of the device sphygmomanometer were 1.4+/-5.3 mmHg for systolic BP (SBP) and -1.4+/-4.5 mmHg for diastolic BP (DBP) in the study group. The device passed phase 1 in 15 patients. In phase 2.1, from the total 99 comparisons, 76, 92, and 97 for SBP and 77, 94, and 99 for DBP were less than 5, 10, and 15 mmHg, respectively. The Omron M6 passed phases 2.1 and 2.2 in the elderly group of patients. CONCLUSION: The Omron M6 (HEM-7001-E) upper-arm BP monitor passed according to the International Protocol criteria and can be recommended for use in elderly patients.     

Diffuse alveolar hemorrhage as an unusual presentation of systemic lupus erythematosus

Diffuse alveolar hemorrhage (DAH) is rarely seen in patients with systemic lupus erythematosus (SLE), often associated with a poor outcome. It almost affects young women and it is an unusual initial manifestation of SLE. We report a case of SLE presenting with DAH. The patient was a male. He had no history of photosensitivity, malar rash, discoid rash, arthritis, and oral ulcer. Antinuclear antibody, and anti-double stranded DNA (dsDNA) were positive with very high titers, and serum complement levels (C3, C4) were low. He also had renal dysfunction and pericardial effusion. He was diagnosed as DAH due to SLE. He had to undergo hemodialysis for several weeks. DAH and renal dysfunction were improved with intensive treatment including corticosteroid, cyclophosphamide, and mycophenolate mophetil.     

Tuberculin skin test screening in a military school in Istanbul city center

To investigate the reason of high incidence of annual patients with tuberculosis (TB) in a military school previously known by screening tuberculin skin test (TST) and finding out the proportion of annual infection risk (PAIR), the prevalance of TB infection and the distribution for each grades. Our study is a cross-sectional epidemiologic study made about TB infection. TST were screened for all students in the school. 5 TU PPD was injected to every student and after 72 hours, the results were evaluated by measuring the diameter of enduration. Test was repeated after 10 days for negative reactions. Age, sex, the number of BCG wound, smoking and dwelling for last 5 years were asked from the students and their answers were recorded. More than 10 mm enduration for cases who had no BCG and 15 mm enduration for cases who had BCG were accepted positive. Chest roentgenogram was taken for each student enrolled into the study. Infection prevalance and PAIR were calculated after tests and measurements. The total number of students was 948. Of 917 (96.7%) were male and 31 (3.3%) were female. The mean age was 19.72 +/- 1.25. The mean of TST was 12.79 +/- 5.96 mm for all students. According to the number of BCG scar, the numbers of students, percentage and the mean of TST were like that 70 (7.3%) cases no BCG scar 8.41 +/- 7.87 mm, 393 (41.4%) students one BCG scar, 11.94 +/- 6.26 mm, 343 (36.1%) cases two BCG scars, 13.74 +/- 5.12 mm, 142 (14.9%) students three or more then three scars, 14.97 +/- 4.11 mm. In the students who had no BCG, TST positivity was 50%. TB infection prevalance of entire school and PAIR were 46% and 3.44% (respectively). In this study, we found that increased number of BCG wound associated with the increased diameter of TST enduration. The proportion of unvaccinated students was similar to the same age population in our country but it showed differences in the distribution of regions. The students who started first grade had serious TB infection risk in their first school year. We think that PAIR values derived from TST conversions done in high risky community by screening annual TST could show all aspects of TB infection risk in those community.     

The importance of peripheral immune cells in inflammatory bowel disease.

Background/aims: Inappropriate down regulation of an activated immune system is considered as the main pathogenetic mechanism in inflammatory bowel disease. Migration of circulating cells to a diseased intestine is considered as an important factor in the pathogenesis of inflammatory bowel disease. We aimed to evaluate some features of circulating immune cells in inflammatory bowel disease. Methods: Twenty-two control, 29 Crohn's disease and 17 ulcerative colitis patients were studied. CD2, CD3, CD4, CD8, CD11b, CD11c, CD25, CD45RA, CD45RO, CD54 and HLA DR on the surface of peripheral blood lymphocytes and CD11b, CD11c, CD45RA and CD45RO on the phagocytes were researched with two-color immunofluorescence flow cytometry. Results: The percentages of CD2+ and CD4+ lymphocytes were found significantly reduced in ulcerative colitis. CD3+ and CD8+ lymphocytes in inflammatory bowel disease were higher than in controls. CD45RA+ lymphocytes were found significantly decreased in ulcerative colitis and active Crohn's disease. CD45RO+ lymphocytes and CD45RO+, CD11b+ and CD11c+ phagocytes were significantly increased in Crohn's disease. Conclusions: We demonstrated that there were significant differences between ulcerative colitis and Crohn's disease in the expression of some important surface markers on the peripheral blood immune cells. It seems that circulating CD11b-CD11c and CD45RA-CD45RO expressing phagocytes are important in inflammatory bowel disease and may be useful in distinguishing Crohn's disease from ulcerative colitis. These findings may give us some clues about the immunopathogenesis of inflammatory bowel disease.     

Conscious sedation during endoscopic retrograde cholangiopancreatography: midazolam or midazolam plus meperidine?

BACKGROUND AND OBJECTIVE: No consensus exists for the safest and most effective agent and for optimal drug doses for sedation during endoscopic retrograde cholangiopancreatography (ERCP). We aimed to compare the efficacy of midazolam with that of midazolam+meperidine, which provided comfort for the patient during ERCP. MATERIALS AND METHODS: The patients were randomized to sedation with midazolam only (2.87+/-0.67 mg) (n=48, median age 55.54+/-14.66, 21 women, 27 men) or midazolam (1.82+/-0.71 mg) with meperidine (42.81+/-14.61 mg) (n= 48, median age 55.48+/-2.57, 20 women, 28 men). Procedure-related parameters and the efficacy of sedation as assessed by the endoscopist and the patients were compared. RESULTS: Prior endoscopic history, preprocedure anxiety scores, age, sex, baseline vital signs and type of interventions were similar in both groups. Sedation level, duration of procedure and recovery time were comparable in both groups. Sedation quality assessment scale was significantly higher in the midazolam with meperidine group. Degree of pain sensed during the procedure was significantly lower in the midazolam with meperidine group. Midazolam with meperidine group had better patient satisfaction. Twenty-four hours after the procedure, the degree of amnesia between both sedation groups was similar. The number of patients unwilling to repeat the procedure was distinctly higher in midazolam group. Development of hypoxia and arrythmia in the midazolam and midazolam with meperidine groups were comparable. Two patients in the midazolam group developed paradoxical agitation. CONCLUSIONS: Conscious sedation for ERCP can be successfully and safely achieved by using either only midazolam or a low dose of midazolam with meperidine. Adding of meperidine to midazolam resulted in better patient and endoscopist comfort.

Effect of transcatheter aortic valve implantation on QT dispersion in patients with aortic stenosis

Background QT dispersion （QTd） is a predictor of ventricular arrhythmia. Ventricular arrhythmia is an important factor influencing morbidity and mortality in patients with aortic stenosis. Surgical aortic valve replacement reduced the QTd in this patients group. However, the effect of transcatheter aortic valve implantation （TAVI） on QTd in patients with aortic stenosis is unknown. The aim of this study was to investigate the effect of TAVI on QTd in patients with aortic stenosis. Methods Patients with severe aortic stenosis, who were not candi-dates for surgical aortic valve replacement due to contraindications or high surgical risk, were included in the study. All patients underwent electrocardiographic and echocardiographic evaluation before, and at the 6th month after TAVI, computed QTd and left ventricular mass index （LVMI）. Results A total 30 patients were admitted to the study （mean age 83.2 ± 1.0 years, female 21 and male 9, mean valve area 0.7 ± 3 mm2）. Edwards SAPIEN heart valves, 23 mm （21 patients） and 26 mm （9 patients）, by the transfemoral approach were used in the TAVI procedures. All TAVI procedures were successful. Both QTd and LVMI at the 6th month after TAVI were significantly reduced com-pared with baseline values of QTd and LVMI before TAVI （73.8 ± 4 ms vs. 68 ± 2 ms, P=0.001 and 198 ± 51 g/m2 vs. 184 ± 40 g/m2, P=0.04, respectively）. There was a significant correlation between QTd and LVMI （r=0.646, P〈0.001）. Conclusions QTd, which malign ventricular arrhythmia marker, and LVMI were significantly reduced after TAVI procedure. TAVI may decrease the possibility of ventricu-lar arrhythmia in patients with aortic stenosis.     

Topiramate ameliorates abdominal aorta cross-clamping induced liver injury in rats

Background and Aim:

Ischemia/reperfusion (I/R) injury in the liver occurs after a prolonged period of ischemia followed by restoration of hepatic blood perfusion. During the surgery of abdominal aorta, I/R injury causes damage to lower extremities and many organs, especially liver. The antioxidant and tumor necrosis factor-alpha (TNF-α) suppression effects of topiramate (TPM) have been reported in several studies. We evaluated the potential protective effect of TPM on cellular damage in liver tissue during I/R injury.

Materials and Methods:

Thirty male Wistar albino rats were divided into three groups: Control, I/R, and I/R plus TPM (I/R + TPM) groups. Laparotomy without I/R injury was performed in the control group. After laparotomy, cross-ligation of infrarenal abdominal aorta was applied for 2 h in I/R groups that was followed by 2 h of reperfusion. TPM (100 mg/kg/day) was orally administrated to the animals in the I/R + TPM group for seven consecutive days before I/R procedure.

Results:

The I/R group''s TNF-α and interleukin-6 (IL-6) levels were significantly higher than those of the control (P = 0.010; P = 0.002) and I/R + TPM groups (P = 0.010; P = 0.002, respectively). Asymmetric dimethyl arginine (ADMA) levels of I/R group were higher than the control (P = 0.015) and I/R + TPM groups. I/R caused serious histopathological damage to liver tissue; however, TPM led to very low histopathological changes.

Conclusion:

Our data demonstrated that TPM treatment prominently decreases the severity of liver I/R injury. TPM pretreatment may have preventive effects on liver injury via I/R during intra-abdominal surgery.     

Case report of a patient with osteopoikilosis

Osteopoikilosis (OPK) is an uncommon osteosclerotic dysplasia. There is no exact evidence of its etiology and pathogenesis. Usually, it is an asymptomatic disease, and the diagnosis is made incidentally from radiographs, which show multiple, small, well-defined, variably shaped and widely distributed sclerotic areas over the skeleton. In this study, we report a 54-year-old man who suffers from back and leg pain and was diagnosed OPK by radiologically and review literature.
