Gurbuz, Cenk;Canat, Lutfi;Atis, Gokhan;Caskurlu, Turhan;
International braz j urol , 2011, DOI: 10.1590/S1677-55382011000100010
Abstract: purpose: to investigate whether the use of a disposable needle guide results in a decreased incidence of infectious complication after transrectal prostate needle biopsy (tpnb). materials and methods: fifty five patients who underwent 10-core tpnb were randomized into two groups. a pre-biopsy blood and urine examination was performed in both groups. group 1 (25 patients) underwent biopsy with disposable biopsy needle guide and group 2 (30 patients) underwent biopsy with reusable biopsy needle guide. all patients had a blood and negative urine culture before the procedure. the patients received ciprofloxacin 500 mg twice a day beginning the day before the biopsy and continued for 3 days after. serum c-reactive protein levels and urine and blood specimens were obtained 48h after the biopsy. primary endpoint of the study was to determine the effect of needle guide on the bacteriologic urinary tract infection (uti) rate and secondary end point was to determine symptomatic uti. results: the mean age of the patients was 63.46 (range 55 to 68) years. there were no significant differences regarding the prostate-specific antigen level, prostate size, existence of comorbidity in two groups before the procedure. bacteriologic and symptomatic uti was detected in 4% vs. 6.6% and 4% vs. 3.9% in group 1 and 2 relatively (p > 0.05). conclusion: the use of a disposable needle guide does not appear to minimize infection risk after tpnb. large scale and randomized studies are necessary to determine the effect of disposable needle guide on infection rate after tpnb.

International braz j urol , 2011, DOI: 10.1590/S1677-55382011000200006
Abstract: purpose: to evaluate hyoscine n-butyl bromide (hbb) and three different alpha-1 blockers in the treatment of distal ureteral stones. materials and methods: a total of 140 patients with stones located in the distal tract of the ureter with stone diameters of 5 to 10mm were enrolled in the present study and were randomized into 4 equal groups. group 1 received hbb, group 2 received alfuzosin, group 3 received doxazosin and group 4 received terazosin. the subjects were prescribed diclofenac injection (75 mg) intramuscularly on demand for pain relief and were followed-up after two weeks with x-rays of the kidneys, ureters, bladder and urinary ultrasonography every week. the number of pain episodes, analgesic dosage and the number of days of spontaneous passage of the calculi through the ureter were also recorded. results: the average stone size for groups 1, 2, 3 and 4 was comparable (6.13, 5.83, 5.59 and 5.48 mm respectively). stone expulsion was observed in 11%, 52.9%, 62%, and 46% in groups 1, 2, 3 and 4 respectively. the average time to expulsion was 10.55 ± 6.21 days in group 1, 7.38 ± 5.55 days in group 2, 7.85 ± 5.11 days in group 3 and 7.45 ± 5.32 days in group 4. alpha blockers were found to be superior to hbb (p < 0.05). conclusions: medical treatment of distal ureteral calculi with alfuzosin, doxazosin and terazosin resulted in a signi?cantly increased stone-expulsion rate and decreased expulsion time when compared with hbb. hbb seems to have a negative effect on stone-expulsion rate.

Prenatal testing and termination of future pregnancies in Arab mothers of children with severe defects: impact of Moslem cleric or physician on the decision making  [PDF]
Lutfi Jaber, Gabrielle J. Halpern, Samer Samara
Open Journal of Genetics (OJGen) , 2011, DOI: 10.4236/ojgen.2011.13010
Abstract: The authors investigated: 1) How many of 250 Israeli Arab mothers (50% in consanguineous marriages) of babies with severe congenital anomalies had undergone prenatal testing during pregnancy, and how many had refused termination of pregnancy (TOP) when recommended; 2) Why TOP had been refused; 3) Attitudes regarding prenatal testing and TOP in future pregnancies; and 4) Whether the women would have changed their decision had they been able to talk to a Moslem cleric or Moslem doctor in addition to the regular personnel. Eighty seven (35%) refused to even consider TOP, 55 (22%) agreed to undergo TOP, and 87 (35%) agreed provided the procedure would be performed before 120 days gestation. The remainder were undecided. Of 195 women, the addition of a Moslem religious cleric or physician to the Committee would influence 89 (46%) and 55 (28%), respectively, to change their opinion and agree to TOP, and 26 (13%) and 10 (5%), respectively, to change their opinion and agree to TOP prior to 120 days of gestation. The remainder either continued to refuse TOP or were undecided.

Revista argentina de endocrinolog?-a y metabolismo , 2009,
Abstract: lithium, used as a first line treatment in maniac depression disease, affects the thyroid gland function. in the last papers published between 1999 and 2007, it has been found a high prevalence of hypothyroidism in bipolar patients, especially in females and when starting lithium at a later age. the duration of treatment and lithemia seams to have no correlation with the begining of hypothyroidism. because of the poor literature written about this issue, the aim of this review is to update the last papers published.
Effect of Different Hydrocolloids on Pasting Behavior of Native Water Chestnut (Trapa bispinosa) Starch
Zubala Lutfi,Abid Hasnain
Agriculturae Conspectus Scientificus (ACS) , 2009,
Abstract: The pasting behavior of native Water Chestnut Starch – hydrocolloids mixtures was studied. The effect of Xanthan, Guar, Carboxy Methyl Cellulose and Acacia on Water Chestnut Starch was examined by using micro Viscoamylograph. It was noticed that all hydrocolloids greatly modify the pasting properties of water chestnut starch. Results showed that gelatinization temperature of water chestnut starch was increased by the addition of gum acacia at 0.3 % concentration, whereas guar gum decreased at the same concentration as compared to native water chestnut starch. Xanthan gum and guar gum significantly increased peak viscosity at 0.1 – 0.3 %, but gum acacia at only 0.3 % addition. The breakdown was greatly enhanced by the addition of xanthan gum at 0.1-0.3 % concentrations, but the retrogradation was mostly influenced due to the presence of guar gum at 0.3 %. These results showed that hydrocolloids modify the properties of native water chestnut starch, which can provide a great potential for use in different food products.
El litio y su influencia en la función tiroidea Lithium and the influence in thyroid function
J Calé,RJ Lutfi
Revista Argentina de Endocrinología y Metabolismo , 2009,
Abstract: El Litio, utilizado como tratamiento de primera línea en la enfermedad maníaco depresiva, genera cambios en la fisiología tiroidea. En los últimos trabajos entre los a os 1999 y 2007, se ha encontrado una alta prevalencia de hipofunción tiroidea en pacientes bipolares principalmente en el sexo femenino y a mayor edad. Aparentemente su aparición no se correlaciona con la duración del tratamiento ni con la Litemia. Dada la escasa literatura existente acerca de este tema, el objetivo de esta revisión es actualizar los datos últimamente publicados. Lithium, used as a first line treatment in maniac depression disease, affects the thyroid gland function. In the last papers published between 1999 and 2007, it has been found a high prevalence of hypothyroidism in bipolar patients, especially in females and when starting lithium at a later age. The duration of treatment and Lithemia seams to have no correlation with the begining of hypothyroidism. Because of the poor literature written about this issue, the aim of this review is to update the last papers published.
Effects of Hemoglobin Concentration on Heart Rate Variability
Dr. Mohamed Faisal Lutfi
International Journal of Pharmaceutical and Biological Research , 2011,
Abstract: Context: Previous studies reported decreased heart rate variability (HRV) among subjects with anemia. However, the underlying pathology of anemia may be the direct cause of low HRV which may preclude fromdrawing the conclusion that anemia per se causes diminished HRV. Aim: To detect the relationship between hemoglobin concentrations and HRV. Setting and Design: It was a cross-sectional case-control laboratorybased study. Patients and Methods: The study involved 25 apparently healthy males and 28 females. The ages of both groups ranged between 20 and 38 years. Colorimetry was used for the estimation of random blood glucose and hemoglobin concentrations. Biocom 3000 ECG recorder was used for studying HRV. StatisticalAnalysis: Data were analyzed using SPSS for windows (version 18). Mean heart rate was introduced as a covariate when screening studied variables for significant correlation between hemoglobin concentrations and heart rate variability indices using partial correlations. Results: The mean hemoglobin concentration of themales (mean (M) ± standard deviation (SD) = 14.4 ± 1.4) was significantly higher compared with the mean hemoglobin concentration of the females (M ± SD = 11.6 ± 1.6) (P = 0.000). In contrast to time domain HRV indices, total power (TP), very low frequency (VLF), low frequency (LF) and high frequency (HF) correlate positively with hemoglobin concentrations (correlation coefficients (CC) ≥ 0.27, P < 0.05 for all). Conclusion: Low hemoglobin concentrations are associated with lower TP, VLF, LF, and HF bands of power spectraldensity HRV putting anemic patients at higher cardiac risk.
Correlations between Electrolytes Levels and Heart Rate Variability in Apparently Healthy Subjects
Dr. Mohamed Faisal Lutfi
International Journal of Pharmaceutical and Biological Research , 2012,
Abstract: Context: Previous studies correlating electrolytes levels with heart rate variability (HRV) were conducted exclusively in diseased patients and fail to demonstrate significant correlations, except for a few. Whether absence of significant correlations is physiological or hidden by the associated pathologies is uncertain. Aim: To evaluate the effects of electrolytes concentrations on heart rate variability in apparently healthy subjects. Setting and Design: It was a cross-sectional case-control laboratory-based study. Patients and Methods: The study involved twenty-two apparently healthy males and twenty-three females. Sodium, potassium, calcium, magnesium, hemoglobin and random blood glucose levels, weight, height, blood pressures and HRV were measured according to the standards. Possible confounding factors were introduced as a covariate when correlating electrolytes concentrations with HRV indices using partial correlations. Results: The study involved 23(51.1%) females and 22(48.9%) males. The ages of studied subjects range between 20 – 40 years (Mean (M) ± Standard deviation (SD) = 25.24±4.79 years). M±SD of the body mass indices = 24.74±6.13 Kg/m2, the mean arterial blood pressures = 90.17±9.78 mmHg, Hemoglobin concentrations =13.00±2.48 g/dl, random blood glucose concentrations = 95.69±16.70 mg/dl. There were no significant correlations between sodium, potassium and calcium concentrations and studied short-term HRV indices. In contrast, there is a significant negative correlation between magnesium concentrations and sympathovagal balance (correlation coefficient (CC) = - 0.376, P = 0.020. Conclusion: Sympathetic modulations on heart rate tend to override parasympatheticmodulations as magnesium concentration decreases. Otherwise, there were no significant correlations between sodium, potassium and calcium concentrations and HRV indices.
