To compare self-esteem scores in 12 to 16-year-old adolescents with different Angle malocclusion types in a Peruvian sample.A cross-sectional study was conducted in a sample of 276 adolescents (159, 52 and 65 with Angle Class I, II and III malocclusions, respectively) from Trujillo, Peru. Participants were asked to complete the Rosenberg Self-Esteem Scale (RSES) and were also clinically examined, so as to have Angle malocclusion classification determined. Analysis of covariance (ANCOVA) was used to compare RSES scores among adolescents with Class I, II and III malocclusions, with participants demographic factors being controlled.Mean RSES scores for adolescents with Class I, II and III malocclusions were 20.47 3.96, 21.96 3.27 and 21.26 4.81, respectively. The ANCOVA test showed that adolescents with Class II malocclusion had a significantly higher RSES score than those with Class I malocclusion, but there were no differences between other malocclusion groups. Supplemental analysis suggested that only those with Class II, Division 2 malocclusion might have greater self-esteem when compared to adolescents with Class I malocclusion.This study shows that, in general, self-esteem did not vary according to adolescents malocclusion in the sample studied. Surprisingly, only adolescents with Class II malocclusion, particularly Class II, Division 2, reported better self-esteem than those with Class I malocclusion. A more detailed analysis assessing the impact of anterior occlusal features should be conducted.

Clinanthus milagroanthus S. Leiva & Meerow, sp. nov. is described from the Department of La Libertad in Peru. The new species is most closely related to Clinanthus mirabilis (Ravenna) Meerow, with further affinities to Clinanthus viridiflorus (R. & P.) Meerow. It can be distinguished from Clinanthus mirabilis by its wider leaves, the much more brightly colored and wide spreading limb, and the much lighter colored perigone tube (yellowish green vs. dark green in Clinanthus mirabilis). A conspicuous bulge just proximal to the midpoint of the tube is a unique character of the new species.

It is very uncommon for urothelial carcinoma to develop in an ureterocele. It is generally discovered in an imaging study or in connection with haematuria. We found very few reports in the literature. Here, we report on the case of a 71-year-old male who initially presented with haematuria and low back pain and who then underwent transurethral resection for an intraureterocele tumour. Pathology confirmed urothelial carcinoma.

Congenital generalized lipodystrophy (CGL) is a genetically heterogeneous group of disorders characterized by the absence of functional adipose tissue. We identified two pedigrees with CGL in the community of the Mestizo tribe in the northern region of Peru. Five cases, ranging from 15 months to 7 years of age, presented with generalized lipodystrophy, muscular prominence, mild intellectual disability, and a striking aged appearance. Sequencing of the BSCL2 gene, known to be mutated in type 2 CGL (CGL2; Berardinelli-Seip syndrome), revealed a homozygous deletion of exon 3 in all five patients examined, suggesting the presence of a founder mutation. This intragenic deletion appeared to be mediated by recombination between Alu sequences in introns 2 and 3. CGL2 in this population is likely underdiagnosed and undertreated because of its geographical, socio-economic, and cultural isolation. 2016 Wiley Periodicals, Inc.

In recent years, the bagworm Oiketicus kirbyi (Guilding) has become a pest of increasing importance in Peruvian avocado orchards. A study conducted in six commercial orchards evaluated the ecology of, and feeding damage caused by, bagworms on avocado on the southern coast of Peru. In March 2009, the population of live individuals at different locations consisted of second to sixth larval instars. The sex-ratio in the previous generation of bagworms (the parents of larvae) was female-biased, and the mortality rate was higher for females than males. The percentage of mated females varied between 76.7 and 99.1% and declined when the proportion of males was low. The damage caused by bagworm larvae usually results from defoliation, but in the case of O. kirbyi on avocado, the presence of larvae on the fruits was associated with blemishes that limit the marketability of fruits; thus bagworms cause direct economic losses for avocado growers. Future studies are needed to assess the timing of larval emergence with a view to preventing widespread infestation by dispersing neonate bagworms. © 2010 Taylor & Francis.

To determine trends in the prevalence and identify the main risk factors associated with the development of pancreatic cancer. Study of trends in incidence and case-control population consisted of a total of 134 patients. Patients were grouped into: a) Cases: 67 patients diagnosed with pancreatic cancer treated at the Abdomen's Service of the Specialized Surgery Department of the Regional Institute of Neoplastic Diseases "Dr. Luis Pinillos Ganoza "- IREN North during the period 2008 to 2011; and b) Controls: 67 patients diagnosed with gallstones and / or benign biliary disease treated at Belen Hospital in Trujillo during the period 2008 to 2011. The trend curve of incidence of pancreatic cancer showed a curve almost constant throughout the quadrennium 2008 to 2011, with incidence rates of 5.38%, 5.08%, 5.5% and 5.0% respectively. The overall incidence was 5.37%. The trend function was Y = (1756) ± (0.001) (x), with an R2 = 0.318 (p = 0.436). The main risk factors associated with pancreatic cancer were age bigger and equal to 60 years (p = 0.0001), male sex (p = 0.007), diabetes mellitus (p = 0.002) and family history of malignancy (p = 0.016). The trend in incidence in pancreatic cancer was low and constant in its appearance was significantly influenced by age, gender, and presence of diabetes mellitus and family history of cancer.

Determine the effectiveness of surgical treatment and / or adjuvant to improve the quality of life in patients with colon cancer compared to rectal cancer. Cohort study that evaluated 27 patients diagnosed with colon adenocarcinoma (Group A= 12) and rectum (Group B= 15) resectable treated at the Institute Regional of Neoplastic Diseases of Trujillo since the 1 January 2008 until 31 July 2009. The overall life quality, as assessed by the QLQ-C 30 at 3 months postoperatively was 67.86 +/- 17.90 points vs. 68.50 +/- 11.94 points respectively for the patients of groups A and B (p = 0.934).The social function was better in patients undergoing surgery for Group A than Group B , (37.50 + 13.36 points vs. 60.00 + 13.69 points, p = 0.018). Body image at 3 months assessed by the QLQ-CR-29 had an average score of 28.12 +/- 6.12 points and 50.00 +/- 25.00 points for Group A y B respectively (p = 0.034). The Group A patients had a mean score at 6 months for sexual function of 33.33 +/- 12.91 points, while Group B patients this average score was 65.00 +/- 22.36 points (p = 0.016). Both surgeries for colon and rectal cancer are as effective in improving the overall quality of life of these patients, however the social function, body image, and sexual function is better in colon surgery.

Objective: To compare the efficacy of amoxicillin pre and post to prevent postsurgical removal of third molars infection. Material and method: The clinical trial was conducted in the Department of Dentistry Hospital I El Porvenir-ESSALUD (Trujillo, Peru), between July and November of 2013. The 99 patients were randomized into 3 groups: group 1 received 2. g of amoxicillin one hour before surgery, group 2 received 500. mg of amoxicillin and 500. mg immediately after and every 08. hours for 4 days, and group 3 was not given any antibiotic. The surgical procedure was standardized and performed by the same operator, who was blinded to the procedure. The efficacy in preventing infection was measured by three parameters: pain, oral temperature and discharge. To analyze the proportions comparison test was used with p. <. 0,005. Results: No difference was found between amoxicillin before and after surgery to prevent post extraction of third molars infection (p = 0,60). Furthermore, no difference between those groups and the non-antibiotic administration group was found (p = 0,35 and p = 1,00; respectively). Conclusion: The pre and postoperative administration of amoxicillin are not effective to prevent post extraction of third molars infection. © 2014 SECOM.
