    • Laser lipolysis with a 980-nm diode laser: experience with 400 cases

      Valle Dornelles, Rodrigo de Faria; De Lima e Silva, Adriano; Missel, Juarez; Centurión, Patricio (Sociedade Brasileira de Cirurgia Plástica, 2014-06-11)
      Introduction: Liposuction has undergone several improvements since its first description, including changes in the cannulas, variation in the concentration of the infiltrating solution, and the use of different devices and technologies. The use of laser technology devices for lipolysis and stimulation of skin retraction has contributed to the procedure. This article presents the authors’ experience with laser lipolysis in 400 patients, within a 5-year period, and discusses the principles of the technology and its effect on tissues. Methods: This is a study performed between July 2007 and July 2012 and included 400 patients who underwent laser lipolysis. All procedures were performed following the original protocol – infiltration of cold saline, passage of the cannula with an optic fiber for conducting the energy needed for laser lipolysis, skin retraction, and finally, conventional liposuction. Results: Hospitalization type ranged from outpatient to overnight surgery. Approximately 45% (180 of 400) of patients had minimal bruising, with involvement of 2% or more of the affected body surface. Hematoma, seroma, and dehiscence occurred in a total of 9% (36 of 400) of patients. We did not find any case of thermal burn of the skin. Conclusions: Laser lipolysis performed according to the described technique was safe and reproducible.

      López-Herce, Jesús; Almonte, Enma; Alvarado, Manuel; Bogado, Norma Beatriz; Cyunel, Mariana; Escalante, Raffo; Finardi, Christiane; Guzmán, Gustavo; Jaramillo-Bustamante, Juan C.; Madrid, Claudia C.; Matamoros, Martha; Moya, Luis Augusto; Obando, Grania; Reboredo, Gaspar; López, Lissette R.; Scheu, Christian; Valenzuela, Alejandro; Yerovi, Rocío; Yock-Corrales, Adriana (Lippincott Williams and Wilkins, 2018-03)
      Objectives: To develop a Latin American Consensus about Pediatric Cardiopulmonary Resuscitation. To clarify, reinforce, and adapt some specific recommendations for pediatric patients and to stimulate the implementation of these recommendations in clinical practice. Design: Expert consensus recommendations with Delphi methodology. Setting: Latin American countries. Subjects: Experts in pediatric cardiopulmonary resuscitation from 19 Latin American countries. Interventions: Delphi methodology for expert consensus. Measurements and Main Results: The goal was to reach consensus with all the participating experts for every recommendation. An agreement of at least 80% of the participating experts had to exist in order to deliver a recommendation. Two Delphi voting rounds were sent out electronically. The experts were asked to score between 1 and 9 their level of agreement for each recommendation. The score was then classified into three groups: strong agreement (score 7–9), moderate agreement (score 4–6), and disagreement (score 1–3). Nineteen experts from 19 countries participated in both voting rounds and in the whole process of drafting the recommendations. Sixteen recommendations about organization of cardiopulmonary resuscitation, prevention, basic resuscitation, advanced resuscitation, and postresuscitation measures were approved. Ten of them had a consensus of 100%. Four of them were agreed by all the participants except one (94.7% consensus). One recommendation was agreed by all except two experts (89.4%), and finally, one was agreed by all except three experts (84.2%). All the recommendations reached a level of agreement. Conclusions: This consensus adapts 16 international recommendations to Latin America in order to improve the practice of cardiopulmonary resuscitation in children. Studies should be conducted to analyze the effectiveness of the implementation of these recommendations.

    • Let’s Talk About Sex: The Impact of Partnership Contexts on Communication About HIV Serostatus and Condom Use Among Men Who Have Sex with Men (MSM) and Transgender Women (TW) in Lima, Peru

      Ayer, Amrita; Perez-Brumer, Amaya; Segura, Eddy R.; Chavez-Gomez, Susan; Fernandez, Rosario; Arroyo, Cecilia; Barrantes, Alex; Lake, Jordan E.; Cabello, Robinson; Clark, Jesse L. (Springer, 2021-01-01)
      Sexual communication with partners informs risk assessment and sexual practices. We evaluated participant, partner, and network factors associated with communication about condom use and HIV serostatus and explored their relationships with condomless anal intercourse (CAI) among 446 men who have sex with men (MSM) and 122 transgender women (TW) in Lima, Peru. Generalized estimating equations assessed contextual influences on communication and practices with recent sexual partners. More frequent HIV communication was reported by MSM who: identified as heterosexual, compared to bisexual or gay; characterized partnerships as stable, compared to casual, anonymous, or commercial; or discussed HIV/STIs with close social contacts (p < 0.05). TW in concurrent partnerships discussed condom use more frequently than those in monogamous relationships (p < 0.05). Condom use discussions and alcohol use among MSM were associated with CAI (p < 0.05). Findings highlight complexity in sexual decision-making and call for further study of conversation content and practices to inform HIV prevention messaging.

    • Leucocitos fecales en niños con diarrea aguda: ¿momento de reconsiderar la utilidad clínica de la prueba?.

      Carreazo, Nilton Yhuri; Ugarte, Karim; Huicho, Luis (Sociedad de Gastroenterología del Perú (SGP), 2014-03-24)
      INTRODUCTION. Fecal leukocytes are widely used to identify invasive diarrhea and to make then the decision of prescribing or not antibiotics. This test has been hardly assessed in small hospitals of developing countries with efficient laboratory processes. We aimed to assess the diagnostic performance of different thresholds of fecal leukocytes in children under-five with acute diarrhea. MATERIAL AND METHODS. Retrospective study of clinical and laboratory records in the Pediatric Emergency Hospital, Lima, Peru. All cases with a stool culture and fecal leukocytes independently and systematically performed were studied. Sensitivity, specificity, predictive values, likelihood ratios (LR), and receiver operating characteristics (ROC) curves were calculated. RESULTS. Out of 1,804 stool samples assessed, 901 (49,9%) were positive for one or more bacterial entheropathogens. Sensitivity (Sn), specificity (Sp), and positive LR varied for different thresholds: more than 5 (S: 93.2%, Sp: 21.9%, LR+:), more than 20 (Sn: %, Sp: %, +LR: ), more than 50 (Sn: 74.9%, Sp: 56.7%, +LR: 1.73), and more than 100 fecal leukocytes per high power field (Sn: 60.7%, Sp: 71.9%, LR+: 2.17). The general area under the ROC curve was 0.69 (CI 95%: 0.67-0.72).

    • Leukocytoclastic vasculitis associated with nontyphoidal Salmonella in a patient infected with human immunodeficiency virus

      Cornejo-Venegas, G. (SAGE Publications Ltd, 2020-03-01)
      A 27-year-old Peruvian woman living with human immunodeficiency virus (HIV) in clinical stage B3 and not on antiretroviral therapy presented with a ten-day history of fever, chills, night sweats and a two-day history of skin lesions. On physical examination, several erythematous-purplish lesions were found on the face and legs. Meningococcal infection was suspected and ceftriaxone was started. Blood culture grew nontyphoidal Salmonella enterica. A biopsy of the skin lesions showed leukocytoclastic vasculitis (LCV); therefore, corticosteroids were added. After two weeks of antibiotic and corticosteroid treatment, the lesions had resolved, but they recurred two days after treatment with prednisone was stopped. Corticosteroids and combination antiretroviral therapy were started simultaneously and the lesions resolved without recurrence. HIV infection has been associated with higher rates of skin lesions in salmonellosis. LCV has been described both in the setting of HIV infection and salmonellosis. However, our review of the literature found no previous cases of LCV in concurrent HIV and salmonellosis.

    • Lineage II of Southeast Asian/American DENV-2 is Associated with a Severe Dengue Outbreak in the Peruvian Amazon

      Williams, M.; Mayer, S. V.; Johnson, W. L.; Chen, R.; Volkova, E.; Vilcarromero, S.; Widen, S. G.; Wood, T. G.; Suárez Ognio, Luis; Long, K. C.; Hanley, K. A.; Morrison, A. C.; Vasilakis, N.; Halsey, E. S. (The American Society of Tropical Medicine and Hygiene, 2014-07-07)
      During 2010 and 2011, the Loreto region of Peru experienced a dengue outbreak of unprecedented magnitude and severity for the region. This outbreak coincided with the reappearance of dengue virus-2 (DENV-2) in Loreto after almost 8 years. Whole-genome sequence indicated that DENV-2 from the outbreak belonged to lineage II of the southeast Asian/American genotype and was most closely related to viruses circulating in Brazil during 2007 and 2008, whereas DENV-2 previously circulating in Loreto grouped with lineage I (DENV-2 strains circulating in South America since 1990). One amino acid substitution (NS5 A811V) in the 2010 and 2011 isolates resulted from positive selection. However, the 2010 and 2011 DENV-2 did not replicate to higher titers in monocyte-derived dendritic cells and did not infect or disseminate in a higher proportion of Aedes aegypti than DENV-2 isolates previously circulating in Loreto. These results suggest that factors other than enhanced viral replication played a role in the severity of this outbreak.

      Centurión, Patricio; Olivencia C.; Romero C.; Gamarra García R. (Sociedad Española de Cirugía Plástica, Reparadora y Estética (SECPRE), 2014-06-11)
      Presentamos una innovadora técnica quirúrgica para el tratamiento de la región abdominal, en la cual combinamos lipoescultura y abdominoplastia con incisiones reducidas, sin neoonfaloplastia, en pacientes tipo III según Clasificación de Matarasso. Realizamos un estudio retrospectivo sobre pacientes intervenidos con esta nueva propuesta quirúrgica, entre los años 2002 y 2008. La lipoescultura corporal superficial y profunda incluyó también la pared abdominal anterior. La técnica quirúrgica se basa en el uso de incisiones reducidas a nivel suprapúbico, máximo de 18 cm. de longitud, con disección de un túnel de aproximadamente 10 cm. en plano supraponeurótico, desinserción del ombligo, plicatura de la diástasis de músculos rectos abdominales y posterior reinserción del ombligo inferiormente. Usamos una férula de yeso durante el postoperatorio. Evaluamos 64 lipoabdominoplastias, todas realizadas en mujeres con edad media de 41,9 años. El tiempo quirúrgico promedio fue de 3 horas y media, el volumen aspirado de la pared abdominal anterior tuvo un promedio de 1000 ml. El 14,1% de las pacientes presentaron seroma como complicación. Como conclusión creemos que esta técnica permite buenos resultados estéticos corporales totales al obtener una cicatriz corta, un colgajo abdominal anterior adelgazado y ausencia de cicatriz umbilical.

    • Liposucción con diodo láser 980-nm (LSDL 980-nm): optimización de protocolo seguro en cirugía de contorno corporal

      Centurión, Patricio; Cuba, J.L.; Noriega, A. (Sociedad Española de Cirugía Plástica, Reparadora y Estética (SECPRE), 2014-06-11)
      Introdução: A técnica de lipoaspiração recebeu várias contribuições desde sua primeira descrição, como modificações nas cânulas, variação na concentração da solução de infiltração e uso de aparelhos com tecnologias variadas. A utilização de aparelhos com tecnologia laser vem contribuir com o procedimento por meio da lipólise e com o estímulo de retração cutânea. Neste artigo é apresentada a experiência dos autores com a laserlipólise em 400 pacientes, no intervalo de 5 anos, sendo discutidos aspectos dos princípios da tecnologia e sua ação sobre os tecidos. Método: Estudo realizado entre julho de 2007 e julho de 2012, que incluiu 400 pacientes submetidos a procedimento de laserlipólise. Os procedimentos foram realizados seguindo protocolo original, com infiltração de soro gelado, passagem da cânula com fibra óptica para a condução da energia laser visando à laserlipólise, retração cutânea e, por último, lipoaspiração convencional. Resultados: O período de internação variou de cirurgia em regime ambulatorial a pernoite. Cerca de 45% (180/400 pacientes) dos pacientes evoluíram com equimoses mínimas, com acometimento de 2% ou mais da superfície corporal comprometida. Os casos de hematoma, seroma e deiscência totalizaram 9% (36/400 pacientes). Em nenhum caso foi constatada queimadura por lesão térmica na pele. Conclusões: O procedimento de laserlipólise realizado com a técnica descrita demonstrou segurança e reprodutibilidade

    • Localización y tamaño de los adenomas del colon como factores asociados a displasia de alto grado

      Arévalo, Carlo; Chunga, Natalia; Alarcón, Steven; Rodríguez, Omar; Arévalo, Fernando; Montes, Pedro; Monge, Eduardo (Sociedad de Gastroenterología del Perú (SGP), 2017-12)
      Objective: To determine whether localization and size are related to the presence of high-grade dysplasia of colon adenomas in patients of a Peruvian hospital. Materials and methods: This is a descriptive transversal study. We checked colonoscopy reports of 2014-2015 years of Hospital Daniel Alcides Carrion, we included the polyps found in patients older than 18 years old, and excluded reports from patients with colorectal cancer, an antecedent of oncological surgery, inflammatory bowel disease and polyposis (6 or more). We used data based on localization (proximal and distal colon, based on the splenic angle), size (less than 10 mm and 10 mm or more), shape (pediculate and sessile) and grade of dysplasia (low and high-grade). We calculated the strength of association by OR, and we determined whether there was association by Chi-square test with a significance value less than 0.05. Results: We reviewed a total of 1710 of colonoscopy reports, 378 patients had polyps, so the adenoma detection rate was 22.1%. There were 458 polyps, from which 254 were adenomas. From these adenomas, we found an association between distal colon localization and high-grade dysplasia (OR 2.68 IC 1.12-6.42, p<0.05); likewise, there was an association between the size of the adenomas and high-grade dysplasia (OR 7.75 IC 3.05-19.69, p<0.05). We did not find any association between the shape and grade of dysplasia. Conclusion: This study concludes that there is an association between the size of 10 mm or more and localization in the distal colon with high-grade dysplasia of adenomas.
