A series of 40 patients with TIA (25 males and 15 females) was thoroughly investigated by means of angiography and computerized tomography, and divided into a group (A) of 15 “sine materia”, and a group (B) of 25 with direct or indirect evidence of vascular occlusive or stenotic changes. Blood viscosity at 230 sec-1 37° was cp 4.2 ± 0.3 in the controls, cp 4.7 ± 0.7 in all patients (p < 0.05) cp 4.98 ± 0.7 in all male patients (p < 0.01 versus male controls), and cp 4.75 ± 0.8 in group B (p < 0.02). Haematocrit and Fibrinogen were also significantly increased in all male patients and in group B. Circulating platelet aggregates (CPA) were increased in 40% of the patients. Almost all patients with elevated CPA were males, with a slight prevalence in group B. Changes in blood viscosity parameters and in platelet aggregation in TIA patients were therefore related both to evidence of vascular lesions, and to sex, since they were found to prevail in male patients of both groups.

According to this facility's protocol for the treatment of anemia in hemodialyzed patients, androgens were administered to male patients aged over 50 yr and recombinant human erythropoietin was administered to male patients below 50 yr of age and to female patients. In the study presented here, both therapeutic approaches have been prospectively analyzed. Patients were divided into two groups. Group A was composed of 18 patients, aged 62 +/- 12 yr, treated with nandrolone decanoate (200 mg/wk im) for 6 months; Group B was composed of 22 patients (6 men, 16 women) aged 47 +/- 15 yr, treated with subcutaneous recombinant human erythropoietin (initial dose, 6000 IU/wk) for 6 months. The increases of hemoglobin were similar in both groups; Group A, from 7.3 +/- 0.8 to 10.8 +/- 1.7 g/dL (P < 0.001), and Group B, from 7 +/- 0.6 to 10.4 +/- 1 g/dL (P < 0.001). In Group A, increases of triglycerides (159 +/- 71 versus 267 +/- 153 mg/dL, P < 0.001), serum albumin (3.9 +/- 0.3 versus 4.2 +/- 0.3 g/dL, P < 0.05), and dry weight (62.1 +/- 9.8 versus 64.9 +/- 10.1 kg, P < 0.001) were observed, which remained unmodified in Group B. Blood pressure control worsened in one patient (6%) from Group A, and in ten patients (45%) from Group B (P < 0.05). In conclusion, androgens produced an improvement in anemia in selected patients, similar to that achieved by use of recombinant human erythropoietin but at a lower cost. Androgens also have an appreciable anabolic effect and did not increase the blood pressure.

Background: Laparoscopic Cholecystectomy is now accepted as being safe for acute cholecystitis. However, it has not become routine, because the exact timing and approach to the surgical management remains ill define. Careful selection of patients, the knowledge of typical procedure-related complications, and their best treatment are the key points for a safe Laparoscopic Cholecystectomy. Objective: To compare the early and delayed Laparoscopic Cholecystectomy in the acute phase in terms of frequency of conversion to open cholecystectomy. Study Design: Randomized clinical trial. Settings: Department of Surgery, Divisional Headquarter Hospital, Faisalabad. Punjab Medical College, Faisalabad Pakistan. Duration: Study was carried out over a period of six months from June 2018 to May 2019. Methodology: A total of 152 cases (76 cases in each group) were included in this study. All patients were randomly allocated to either group i.e., group -A early Laparoscopic Cholecystectomy and group-B delayed Laparoscopic Cholecystectomy. Results: Mean age was 39.09 + 8.8 and 37.05+ 8.5 years in group- A and B, respectively. In group-A, male patients were 48 (63.2%) and female patients were 28 (36.8%). Similarly, in group-B, male patients were 41 (53.9%) and female patients were 35 (46.1%). Conversion to open cholecystectomy was required in 6 patients (7.9%) of group-A and 16 patients (21.0%) of group – B. Significant difference between two groups was observed (P= 0.021). Conclusion: Early laparoscopic cholecystectomy for acute cholecystitis is safe and feasible in terms of less frequency of conversion to open cholecystectomy.

Objective: (1) To evaluate the effects of G-CSF in eliminating infection in diabetic foot wound (2) Tocompare the effects with conventional diabetic foot management. Design: Prospective, open, randomized comparativestudy. Setting: Medical&Surgical Department of Allied, DHQ Hospital & Nawaz Medicare Faisalabad. Period: FromJan 2000 to Nov 2000 Patients & Methods: Fifty diabetic patients with foot infections were included in this study. Themean age was 52 years ranging from 27 to 60 years. They were divided into two equal groups(Group A and Group B).Results: The male patients were 41(82%) and female 9(18%). Forty six percent of patients were on oral hypoglycaemicdrugs, and 54% on insulin. The trauma preceding infection was 20%, Peripheral neuropathy 94% and peripheralvascular disease 34%. Thirty two percent of patients were smoker. Group A were subjected to G-CSF ( Neupogen )therapy (n=25) subcutanously daily for 5days in addition to conventional measures. Whereas patients in Group Breceived only conventional therapy. Both groups received similar antibiotic and insulin treatment. G-CSF therapy wasassociated with earlier eradication of pathogens from the infected ulcer (median 5 [range 2-11] vs11 [6-31] days in thegroup B; (p=<O.000I), quicker resolution of cellulitis (6 vs l4 days; p<O.0001), shorter hospital stay (8 vsl6 days;p<O.000l), and a shorter duration of intravenous antibiotic treatment (7 vs l4 days ;p—0.0001).No G-CSF treatedpatient needed surgery, whereas three patients in group B underwent toe amputation and six had extensivedebridement under anaesthesia (p=0.00 1). G-CSF therapy was generally well tolerated. Conclusion: Granulocytecolony stimulating factor (G-CSF) may be used as a good adjuvant therapy along with conventional measures for themanagement of diabetic foot infection, as it promotes the healing of diabetic foot ulcer/cellulitis and consequentlyprevents many hazardous complications like amputation of limbs, long hospital stays, extensive and prolonged antibioticuse and last but not the least the total misery of the patients.

SummaryThe aim of the present study was to determine whether clinical or laboratory factors can influence the development of single pronucleated zygotes (1PN) and two polar bodies (PB) after ICSI. In total, 341 ICSI cycles performed at FertiClinic-Villa Margherita from January 2012 to December 2014 were enrolled in the study. Group A included 240 cycles with no 1PN−2PB while group B included 101 cycles with one or more 1PN−2PB. Age, stimulation protocol, infertility factor, amount of gonadotropin administered, duration of therapy, peak estradiol levels, number of follicles at maturation triggering, oocytes retrieved and mature oocytes, time between retrieval and injection and sperm characteristics were compared between groups. In opposition to previous results showing no relationship between 1PN occurrence and clinical or laboratory variables, we observed that 1PN−2PB zygote formation seems to be associated with a lower female age, higher level of E2 and higher number of follicles on day of oocyte maturation triggering, higher number of astenozoospermic male patients, more oocytes retrieved at pick-up, more mature oocytes (MII) and longer time to injection.

Abstract. The present work investigates the sex hormone profiles in 50 male patients with liver cirrhosis of different etiology according to the degree of liver dysfunction. The only hormonal impairment in well-compensated cirrhotics (group A) was an increase in mean serum concentrations of estrone, androstenedione, and sex hormone binding globulin. In decompensated cirrhotic patients with ascites (group B), low mean levels of total and free testosterone were found along with normal gonadotropins mean levels. Estrone and androstenedione levels were still elevated, whereas sex hormone binding globulin levels were not different from controls. In decompensated cirrhotics patients with encephalopathy (group C), total and free testosterone mean levels were lower than in group B, and LH mean levels were elevated; estrone levels were markedly high, but androstenedione levels were subnormal; sex hormone binding globulin concentrations were again not different from controls. The few patients with high prolactin levels belonged primarily to this group. Estradiol mean levels were not significantly elevated in any of the groups. It is concluded that the various hormonal patterns of gonadal failure and of the impairment of steroid metabolism and transport, observed in cirrhosis, can be attributed to the degree of liver dysfunction.

Abstract Depending on the intensity, duration and type of physical exercise, equine metabolism has to adapt to nervous, cardiovascular, endocrine and respiratory system requirements. In horses, exercise and training are known to have considerable effects on the mechanisms of hemostatic system involving platelet activity. The aim of the present study was to evaluate the effect of different training schedules on platelet aggregation in 15 Italian Saddle jumping horses. Animals were divided into three equal groups: Group A was subjected to a high intensity-training program; group B to a light training program, group C included sedentary horses. From each animal, blood samples were collected by jugular venipuncture at rest on the 1st, 3rd and 5th days, and afterwards, once a week, for a total of 5 weeks data recording, in order to assess the maximum degree of platelet aggregation and the initial velocity of aggregation (slope) platelet aggregation. Two-way analysis of variance (ANOVA) showed a significant effect of the different training schedules on studied parameters. The results revealed a different degree of platelet aggregation and a different initial velocity of platelet aggregation that changes during the different training schedules in horses that could represent a different protective endothelial mechanism. These findings could have an important role for a clearer knowledge of the physiological reference values of platelet aggregation and for a better interpretation of these variations during the training.

Background Hypotension induced by sodium nitroprusside can minimize intraoperative blood loss. The release of endogenous catecholamines can influence adrenoceptors of platelets and thus might change the ability of platelets to aggregate. Methods Forty patients undergoing nasal septum, tympanoplastic, or sphenoid sinus surgery were randomly divided into two groups, those having controlled hypotension (A) and those serving as controls (B). Blood samples were drawn before the operation, after induction of anesthesia, 1 h after the start of the operation, and on the day after surgery. Results Epinephrine-induced platelet aggregation only increased in the controls on the day after surgery (A: from 49 +/- 25% to 47 +/- 29%; B: from 53 +/- 24% to 72 +/- 14%; mean +/- SD; P &lt; 0.01). Spontaneous platelet aggregation increased in the controls from a median of 1.2 omega/h to 2.4 during the operation and 2.9 on the day after surgery but not after hypotension. On the day after surgery, alpha 2 receptors reached their maximum (A: 238 +/- 164; B: 234 +/- 80 per platelet). During the operation, the norepinephrine concentrations were significantly greater in group A (median, 419 pg/ml) than in group B (median, 217 pg/ml; P &lt; 0.05). Blood loss was greater in the controls (A: 180 +/- 75; B: 379 +/- 120 ml; P &lt; 0.05). Conclusions Controlled hypotension using sodium nitroprusside reduces epinephrine-induced and spontaneous platelet aggregation. Even on the day after hypotension, the usual postoperative reactive increase in platelet aggregation did not occur. These results may be explained by the direct effect of nitroprusside on platelets, the augmented stress response, lower shear stress on platelets due to the lower blood pressure, or the decreased blood loss compared with the controls.

Objective To evaluate the preemptive analgesic effect of submucosal infiltration of ropivacaine for uvulopalatopharyngoplasty. Study Design Randomized controlled trial. Setting Comprehensive clinical center and academic hospital. Subjects and Methods Fifty consecutive male patients scheduled for uvulopalatopharyngoplasty were divided randomly into group A and group B. In group A, 4 mL of 0.33% ropivacaine and normal saline with epinephrine was preincisionally injected under the mucosa on both sides of the tonsillar fossa, soft palate, and the lower part of palatoglossal arch, whereas the upper and middle parts of the palatoglossal arch and the upper part of the palatopharyngeal arch were infiltrated with 2 mL of the same mixture. In group B, an identical volume of normal saline with epinephrine was administered. In both groups, postoperative pain was initially controlled by intravenous morphine titration until patient-controlled analgesia with morphine could be used. Cumulative patient-controlled analgesic morphine consumption; visual analog scale scores at 4, 8, 12, 24, and 48 hours postoperatively at rest and during swallowing; and opioid-related adverse effects were recorded. Results The visual analog score was lower at rest during the 48-hour postoperative period and during swallowing within the first 12 hours for group A versus group B ( P < .05). Patients in group A required 44.1%, 38.2%, and 41.1% less morphine during the first 24 hours, 24 hours to 48 hours, and 48 hours postoperatively, respectively, and fewer patients experienced nausea, vomiting, and pruritus ( P < .05). Conclusion Preemptive submucosal infiltration with 0.33% ropivacaine effectively controlled pain after uvulopalato-pharyngoplasty.

Lower Urinary Tract Symptoms. Alpha-1 adrenoceptor antagonists are mostfrequently prescribed medical management for LUTS and among these tamsulosin andterazosin are the most common. Objectives: To access comparison of efficacy of tamsulosinand terazosin for management of LUTS due to prostatic hyperplasia in terms of InternationalProstate Symptom Score (IPSS). Place and duration: Study being conducted at Departmentof Urology and Kidney Transplantation, Allied Hospital, Faisalabad for period of 24 months from01-07-2014 to 30-06-2016. Methodology: 659 male patients enrolled in study and randomlyassigned to Group A (Patients being administered with tamsulosin) and Group B (Patients beingadministered with terazosin) and improvement in IPSS monitored over period of two weeks.Results: 659 patients enrolled with mean age+sd as 61.9+10.2 years. Group A includes 330patients while Group B include 329 patients. Among Group A, 250 patients showed significantimprovement in IPSS while in Group B, 215 patients showed significant response to medicalmanagement in terms of IPSS and both groups showed statistically comparative response.Statistical response of management also determined in terms of variables of IPSS severity,prostatic size and age of patient and found that efficacy of the two groups were statisticallycomparable for patients with mild IPSS while in patients with moderate IPSS has response totreatment with tamsulosin but no statistical association of efficacy for treatment with terazosin.No statistical response was found for improvement in symptoms in cases with severe IPSS ineither groups. When response monitored in terms of prostate size in both groups, it was foundthat both groups have statistical response when prostate size is less than 35 grams, between35-55 grams but in case when prostate size was more than 55 grams, no statistical responsewas found with group B patients. When response was measured in terms of variable of age,results were consistent with the fact that statistically significant response of efficacy was foundin either groups for age group 45-55 years and 56-65 years but no statistical response wasfound for Group B when considered for age group more than 65 years. Conclusion: Based onresults it is concluded that both tamsulosin and terazosin has got comparative results in overallresponse. However, tamsulosin has superiority in treatment when IPSS is moderate, prostatesize is more than 55 grams and age of patient is more than 65 years.
