Prevalence of depressive symptoms among college students and the influence of sport activity.

The present study asses the prevalence of depressive symptoms among college students in Split, Croatia, and positive influence of sport activity on decreasing the depression symptoms. Authors screened all 664 college students of the first year of study. All of them were over the 18 years and the mean age was 19.4 +/- 1.2 years. There were 466 females (70.2%) and 178 (26.8%) males. They answered The Beck Depression Inventory (BDI) and questionnaire about their sport activity (no sport activity, recreational and active in sports). For the purpose of the analysis depressive symptoms were defined as a score of > 11. Chi-square and Mann-Whitney test were used for data analysis. 9.4% of the students had significant depression symptoms (score > 11). No one student had score > 26 (symptoms of major depression). Statistically significant lower score on BDI have students who are active in sports (score median = 3) compared to group of recreational (score median = 4) and in correlation to group who are not active in sports (score median = 5) (Kruskal-Wallis: p < 0.001). In the group of active in sports (N = 254) there are only 5.5% with depressions symptoms, while in the group of non active in sports (N = 60) are 18 depressive (chi2-test: p = 0,005). Females are statistically more depressed than males (chi2-test: p = 0.01). In the female group 49 (10.5%) are depressed, and in the male group are 9 (5%). Compared to gender in separate analysis we did not find correlation of decreasing depression symptoms and sport activity among males (chi2-test: p = 0.47), while in females we find that sport activity has significant effect (chi2-test: p = 0.026). Our results shoved moderate values of depression symptoms among college population in Split, Croatia. More females than males experienced depressive symptoms. While sport activity did not have significant influence on the depression in male population, it has significant influence in reducing the depression symptoms among females.

Quality of the blood sampled from surgical drainage after total hip arthroplasty.

Several methods have been found to be successful in reducing the need for allogeneic transfusion among the patients undergoing total hip replacement. The purpose of this prospective study was to analyse the quality and evaluate the effect of postoperative autotransfusion on the need for allogeneic transfusion following total hip replacement. The prospective study was performed in two groups of patients undergoing total hip replacement. Before the operative procedure all patients in both groups predonated two doses of autologous blood. In GROUP 1. the system for postoperative collection and transfusion of shed blood was used. In GROUP 2. the patients underwent total hip replacement without blood salvage system. Standard suction collection sets were used postoperatively. In this group shed blood was not transfused to the patients. The samples of preoperative donated autologus blood, allogeneic blood and postoperative collected autologous blood were analysed for number of red cells, hemoglobin, hematocrit, platelets, white blood cells, values of potassium, sodium, free hemoglobin and acid base status. The postoperatively blood salvage significantly reduced the use of allogeneic transfusion among patients managed with total hip replacement (allogeneic transfusion received 12% patients in Group 1 and 80% patients in Group 2; p<0.001). The values of red blood cells are significantly lower in postoperative collected autotransfusion blood compared with preoperative collected autologous blood and allogeneic blood (p<0.001). The values of potassium and acid base status were in normal range in postoperatively collected autotransfusion blood. These values in preoperatively collected autologous blood and allogeneic blood were out of normal range; (p<0.001). In addition to reducing the risk of complications that are associated with allogeneic transfusion, postoperative blood salvage may offer benefits including reducing the need for allogeneic blood. Our study confirmed that postoperative collection and transfusion of drainaged blood is simple and safe method that significantly reduce the need for allogeneic transfusion in patients underwent total hip replacement. The blood collected and transfused postoperatively has lower values of red blood cells and normal values of potassium and acid base balance. The transfusion of this blood caused no complications in our patients.

The analysis of walk cycle in patients with spastic cerebral palsy after surgical management on the lower extremity.

Gait pattern is a frequent problem in cerebral palsy. The aim of the investigation is the evaluation of proximal femur normalization and/or pelvis normalization after surgical correction and simultaneous operations on soft tissues of lower limbs, as well as walk analysis. From 1980. to 2000. were operated 856 patients, 476 male and 380 female, between 1-51 years. Basic walk parameters were analyzed: step length, speed and the number of steps in one minute (cadence). 75.25% of patients had good results with improved of centrum collum diaphysis (CCD) and angle of anteversion (AV) or antetorsion (AT) for 70%, and more independent walking with contracture corrections and decreased spasticism. The best results were achieved with simultaneous two-side operations, with patients' age between 1 and 3, achieving independent walking. More operations at the same time significantly reduce spasticism--one anesthesia, one immobilization, and later same time post-operative physical therapy and satisfactory better results.

Effects of clonidine preemptive analgesia on acute postoperative pain in abdominal surgery.

Preemptive analgesia refers to blockade of afferent nerve fibers before a painful stimulus, which prevents or reduces subsequent pain even beyond the effect of the block. The aim of the study was to compare the effect of clonidine used before and at the end of operation on pain control in abdominal surgery. A total of 77 patients admitted for colorectal surgery were randomly classified into three groups: epidural clonidine before operation, epidural clonidine at the end of operation, and control group. After the operation on patient demand, analgesia with boluses of epidural morphine was instituted. The parameters of postoperative pain level using VAS score (visual analog scale), sedation and analgesics consumption were determined as outcome measures at 1, 2, 6, and 24 h of the operation. Clonidine administered before operation provided lowest pain scores at 6 and 24 h (p < 0.05). Clonidine administered at the end of operation had low pain scores at 1 and 2 h, with a significant pain breakthrough thereafter (6.93 +/- 1.66 at 6 h and 4.04 +/- 2.39 at 24 h) compared with the group administered clonidine before operation (3.60 +/- 2.94 and 3.71 +/- 1.82). Clonidine administered before operation provided less sedation (p < 0.05) and a significantly lower use of analgesics (p < 0.05). Blockade of nociceptive stimulus using the centrally acting alpha2-adrenergic agonist clonidine before the onset of pain stimulus resulted in reduced pain levels, sedation and analgesic requirement.

Large-gauge needle biopsy in diagnosing malignant breast neoplasia.

This paper is concerned with large-gauge needle biopsies of suspicious breast neoplasia performed within a three-year period (22nd June 1999 through 21st December 2001). Within that time 262 large-gauge needle biopsies as well as cytological punctions were performed with the aim of diagnosing benign and malignant neoplasia. In the same three-year period 29 malignant breast tumors were diagnosed. In one of the patients a clinically and PHD verified alteration was found which pointed to Mb. Padget, while in another patient an atypical ductal hyperplasia was confirmed by a pathohistological test.
