The aim of the study was to assess cephalometric abnormalities in the tegumentary profile of patients with Class II malocclusion. Twenty patients with average age of seven years and eight months were divided into: Group I - control, Class I, no malocclusions (n=10); Group II – Class II malocclusion (n=10). Standardized radiography was performed for the obtainment of the cephalometric points. Langlade’s classification was employed and the features were used: GN.Sn.Pog, ANL,A´-Gv, Pog´- Gv, Ls-GV, Li-GV, Sls-Gv, Sli-Gv. The Student’s t-test and Pearson’s correlation were used, with the level of significance set at 5%. The results show that the patients with Class II had more convex tegumentary profile, less protruded mid face and upper lip, less depth of the upper lip groove and more retracted lower lip and tegumentary chin, with statistically significant differences between groups (p0.005). The conclusion is that the patients with Class II malocclusion exhibited cephalometric abnormalities in the tegumentary profile.

ABSTRACT Objective To investigate potential intravenous drug incompatibilities and related risk factors in a pediatric unit. Methods A cross-sectional analytical study conducted in the pediatric unit of a university hospital in Brazil. Data on prescriptions given to children aged 0-15 years from June to October 2014 were collected. Prescriptions that did not include intravenous drugs and prescriptions with incomplete dosage regimen or written in poor handwriting were excluded. Associations between variables and the risk of potential incompatibility were investigated using the Student’s t test and ANOVA; the level of significance was set at 5% (p<0.05). Relative risks were calculated for each drug involved in potential incompatibility with 95% confidence interval. Results A total of 222 children participated in the study; 132 (59.5%) children were male and 118 (53.2%) were aged between 0 and 2 years. The mean length of stay was 7.7±2.3 days. Dipyrone, penicillin G and ceftriaxona were the most commonly prescribed drugs. At least one potential incompatibility was detected in about 85% of children (1.2 incompatibility/patient ratio). Most incompatibilities detected fell into the non-tested (93.4%), precipitation (5.5%), turbidity (0.7%) or chemical decomposition (0.4%) categories. The number of drugs and prescription of diazepam, phenytoin, phenobarbital or metronidazole were risk factors for potential incompatibility. Conclusion Most pediatric prescriptions involved potential incompatibilities, with higher prevalence of non-tested incompatibilities. The number of drugs and prescription of diazepam, phenobarbital, phenytoin or metronidazole were risk factors for potential incompatibilities.

ABSTRACT The objective of this study was to investigate the effect of the ketoprofen on the preemptive analgesia in female cats submitted to ovariohysterectomy. Sixteen healthy cats were distributed into two groups, with eight animals each, by means of a draw, in a preemptive group (PREG), in which the animal received ketoprofen (1 mg/kg) subcutaneously two hours before the surgery; and postsurgery group (POSG), in which ketoprofen (1 mg/kg) was administered subcutaneously immediately after surgery. In both groups, ketoprofen was given 24, 48 and 72 hours after the first adminstration. Heart and respiratory frequencies and glycemia were measured in all animals during the days first ten postsurgery. Analgesia was measured by assigning scores at zero, two, four, six, 12, 24, 48, 72, 96, 120, 144, 168, 192, 216 and 240 hours after the surgical procedure. Statistical analysis was performed using two-way analysis of variance followed by Tukey's test to compare the moments and Student's t-test for comparison between groups. Pain scores were evaluated using test of U-Mann-Withney or Kruskall-Wallis, all at the 5% level of significance. Pain scores were significantly lower in PREG in M0, M6, M72, M96 and M120. No significant difference was found in the levels of glycemia in comparison to baseline values. Ketoprofen promotes postsurgery analgesia in female cats submitted to ovariohysterectomy and preemptive and postsurgery administration provides an earlier reduction of pain scores when compared to postoperative administration, only.

This study aims to explore the association between nurses' leadership styles and personal and professional nursing profile and workload. The sample consisted of seven nurses and seven nursing technicians who were grouped into pairs. At the end of three months, nurses were queried regarding what leadership style would be adopted when the nursing technician under their evaluation delivered care to patients admitted to the ICU. Relevant data was analyzed by applying descriptive statistics, Tukey's multiple comparison test and Student's t-test (p< 0.05). Nursing workload reached 80.1% on average. The personal and professional profile variables did not show any relation with the leadership styles chosen by nurses (p>0.05). The determine, persuade, and share leadership styles prevailed. However, whenever the nursing workload peaked, the determine and persuade styles were used (p<0.05).

Intravesical prostaglandin E2 is effective in the recovery of spontaneous voiding after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. The aim of the study was to compare the effects of intravesical prostaglandin E2 in the prevention of urinary retention after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. STUDY DESIGN: From November 1996 to June 1999 fifty women underwent the Lahodny procedure for moderate/severe cystocele and stress urinary incontinence. Women were randomly assigned to 1 of the 2 study groups: intravesical prostaglandin E2 versus controls. Data obtained were analyzed with the Student t test and the Fisher exact test. RESULTS: Two patients of the treatment group had to be excluded from the study, one because of the wrong measurement of the post-voidal residual volume and another due to a fastidious burning sensation which appeared immediately after prostaglandin instillation and required the suspension of the treatment. No other side effects such as nausea, vomiting, diarrhea or hyperthermia were observed. Patients who underwent the prostaglandin E2 treatment showed a recovery of spontaneous voiding after 7.9&plusmn;6.7 days, whereas this interval was significantly longer in the control group, being 12.9&plusmn;9.7 days (p=0.04, Two tailed Unpaired Student's T test). CONCLUSION: The effectiveness and the low associated morbidity mark the treatment with intravesical prostaglandin E2 useful in the recovery of normal voiding after transvaginal pubocervical fascia reconstruction and short arm sling with the procedure according to Lahodny.

Very little studies were done on relationship of the dental status and the nutritional status. The present study was done to study relation between edentulism and the presence of anemia. The study was included of 46 adult patients with edentulism and same numbers of patients were taken as controls. The results were tabulated and analyzed with the help of IBM SPSS statistics 20 using student’s t test. The hemoglobin levels were lower in the edentulous patients that that of the control group. The present study had shown that the nutritional status were poor resulting in anemia in case of edentulous patients as compared to control group with the same age group.

Functional and structural damages of tubulointerstitium are caused by proteinuria. The aim of this study was to assess the influence of different proteinuria levels on Na+, K+, Cl tubular transport. We examined 50 patients (24 males, 26 females), mean age 46.50 ? 13.08 years, with mean creati-nine clearence of 87.29 ? 31.17 mL/min. They were separated in three groups depending on proteinuria value. The first group with proteinuria less than 0.3 g/24h included 19 persons (7 males, 12 females), mean age 45.12 ? 13.28 years, with mean creatinine clearance of 94.27 ? 34.70 mL/min. The second group of 18 patients (8 males, 10 females), mean age 45.39 ? 12.64 years had proteinuria of 0.3-3,0 g/24h and mean creatinine clearance of 90.07 ? 31.89 mL/min. The third group had proteinuria level higher than 3.0g/24h and mean creatinine clearance of 73.25 ? 20.44 mL/min. It included 13 patients (9 males, 4 females), mean age 50.08 ? 13.73 years. As a parameter of proteinuria influence on tubular transport of Na+, K+ and Cl-, fractional excretion of these electrolytes, was studied. Student's T test, Mann Whitney U test and c2 test were used for statistical analysis. No statistically significant influence of proteinuria was found on Na+, K+ and Cl tubular transport.

ΣΚΟΠΟΣ: Η συλλογή, ανάλυση και επεξεργασία στοιχείων ογκολογικών ασθενών που νοσηλεύθηκαν στη Μονάδα Εντατικής Θεραπείας (Μ.Ε.Θ.) και η συσχέτισή τους με συγκεκριμένους πιθανούς παράγοντες κινδύνου .ΥΛΙΚΟ: Πρόκειται για μία προοπτική μελέτη παρατήρησης (prospective observational) σε δείγμα 125 ογκολογικών ασθενών που νοσηλεύθηκαν στη Μ.Ε.Θ. κατά την τελευταία διετία.ΜΕΘΟΔΟΣ: Αξιολογήθηκαν επιδημιολογικοί, κλινικοί και λειτουργικοί παράγοντες. Ειδικότερα ελέγχθηκαν η πρωτοπαθής νεοπλασματική νόσος, η ηλικία, η παρουσία στεφανιαίας νόσου, χρόνιας αποφρακτικής πνευμονοπάθειας, σακχαρώδους διαβήτη, νεφρικής ανεπάρκειας, ο δείκτης μάζας σώματος, η εφαρμογή χημειοθεραπείας ή και ακτινοθεραπείας, η διάρκεια νοσηλείας, τα score βαρύτητας (APACHE II, SAPS II, SOFA) και η έκβαση (εξιτήριο ή θάνατος) και έγιναν συσχετίσεις με τα προηγούμενα στοιχεία. Χρησιμοποιήθηκε το στατιστικό λογισμικό πακέτο SPSS 17.0 (SPSS, Chicago, IL, USA) για Windows. Οι συνεχείς μεταβλητές παρουσιάζονται ως μέσοι όροι + τυπική απόκλιση (mean + standard deviation). Για τη σύγκριση των μέσων όρων μεταξύ δύο ομάδων έγινε χρήση του student’s t-test, εφόσον οι μεταβλητές ακολουθούσαν την κανονική κατανομή και του Mann-Whitney U test στην αντίθετη περίπτωση. Για την ανάδειξη συσχετίσεων μεταξύ ποιοτικών μεταβλητών έγινε χρήση του x2 test.ΑΠΟΤΕΛΕΣΜΑΤΑ: Η θνητότητα ανήλθε στο 48.8%. Στατιστικά σημαντικοί παράγοντες κακής έκβασης κατά την εισαγωγή του ασθενούς στη ΜΕΘ ήταν τα score βαρύτητας (APACHE II, SAPS II, SOFA), το πτωχό performance status και τα συνυπάρχοντα σοβαρά νοσήματα. Στατιστικά σημαντικοί παράγοντες κακής έκβασης κατά τη διάρκεια νοσηλείας του ασθενούς στη Μ.Ε.Θ. ήταν η διάρκεια του μηχανικού αερισμού, η χρήση αγγειοσυσπαστικών, η πολυοργανική ανεπάρκεια και η σηπτική κατάσταση. Από τις εργαστηριακές εξετάσεις στατιστικά σημαντικές ήταν ο χαμηλός αριθμός αιμοπεταλίων και η θετική αιμοκαλλιέργεια. Ο στατιστικός έλεγχος αξιολόγησης κατά Hosmer Lemeshow παρά τον σχετικά μικρό αριθμό του δείγματος επιβεβαίωσε τη χρησιμότητα των APACHE II, SAPS II, SOFA ως προγνωστικών μοντέλων.ΣΥΜΠΕΡΑΣΜΑΤΑ: Η πρόγνωση ογκολογικών ασθενών που εισάγονται στη ΜΕΘ είναι μέτρια. Υπάρχουν σαφείς προγνωστικοί παράγοντες κινδύνου που μπορούν να συνθέσουν ένα είδος προγνωστικού μοντέλου, ωστόσο απαιτούνται περαιτέρω πολυκεντρικές μελέτες με προοπτικό χαρακτήρα σε μεγαλύτερο αριθμό ασθενών.
