Transanal minimally-invasive surgery (TAMIS): experience with no closure of the rectal defect

Background: In transanalminimally-invasive surgery (TAMIS), the closure of the rectal defect is controversial, and endoluminal suture is one of the most challenging aspects. The goal of the present study is to evaluate the short- andmedium-term complications of a consecutive series of patients with extraperitoneal rectal injuries who underwent TAMIS without closure of the rectal defect. Materials and Methods: A prospective, longitudinal, descriptive study conducted between August 2013 and July 2019 in which all patients with extraperitoneal rectal lesions, who were operated on using the TAMIS technique, were consecutively included. The lesions were: benign lesions ≥ 3 cm; neuroendocrine tumors ≤ 2 cm; adenocarcinomas in stage T1N0; and adenocarcinomas in stage T2N0, with high surgical risk, or with the patients reluctant to undergo radical surgery, and others with doubts about complete remission after the neoadjuvant therapy. Bleeding, infectious complications, rectal stenosis, perforations, and death were evaluated. Results: A total of 35 patients were treated using TAMIS without closure of the defect. The average size of the lesionswas of 3.68±2.1 cm(95% confidence interval [95%CI]: 0.7cmto 9 cm), their average distance from the anal margin was of 5.7±1.48cm, and the average operative time was of 39.2±20.5 minutes, with a minimum postoperative follow-up of 1 year. As for the pathologies, they were: 15 adenomas; 3 carcinoid tumors; and 17 adenocarcinomas. In all cases, the rectal defect was left open. The overall morbidity was of 14.2%. Two patients (grade II in the Clavien-Dindo classification) were readmitted for pain treatment, and three patients (grade III in the Clavien-Dindo classification) were assisted due to postoperative bleeding, one of whom required reoperation. Conclusion: The TAMIS technique without closure of the rectal defect yields good results, and present a high feasibility and low complication rate. (AU)

Evaluation of pulping therapy in deciduous teeth using chlorhephenicol tetracycline and Zinc oxide / Avaliação da terapia pulpar em dentes decíduos com uso da pasta cloranfenicol tetraciclina e óxido de Zinco

ABSTRACT The technique using CTZ paste (chloramphenicol, tetracycline, and zinc oxide-eugenol) in the endodontic treatment of deciduous teeth is easy to perform and requires a single session, which is an advantage with child patients. The inexistence of clinical protocols with the use of CTZ and the multifactorial endodontic repair process in deciduous teeth evidence the need for research on the subject. This study aimed to suggest a clinical protocol model for the systematization and standardization of the endodontic treatment of deciduous teeth using CTZ paste. In the case report presented, after pulp therapy, clinical-radiographical follow-up was conducted after 30, 60, 90 and 180 days. It was concluded that using CTZ paste is a simple, viable, and satisfactory alternative. Future clinical studies are needed regarding CTZ use in child clinic with strong scientific evidence.

RESUMO A técnica com pasta CTZ (cloranfenicol, tetraciclina e óxido de zinco-eugenol) no tratamento endodôntico de dentes decíduos é de fácil execução e requer sessão única, o que é uma vantagem em pacientes infantis. A inexistência de protocolos clínicos com o uso do CTZ e do processo de reparo endodôntico em dentes decíduos evidencia a necessidade de pesquisas sobre o assunto. Este estudo teve como objetivo sugerir um modelo de protocolo clínico para a sistematização e padronização do tratamento endodôntico de dentes decíduos com a pasta CTZ. No relato de caso apresentado, após a terapia pulpar, o acompanhamento clínico-radiográfico foi realizado após 30, 60, 90 e 180 dias. Concluiu-se que o uso da pasta CTZ é uma alternativa simples, viável e satisfatória. Futuros estudos clínicos são necessários a respeito do uso de CTZ em clínica infantil com fortes evidências científicas.

What patients consider to be a good doctor, and what doctors consider to be a good patient / Cómo definen los pacientes a un buen médico, y cómo definen los médicos a un buen paciente

ABSTRACT Background: From a patient's point of view, an 'ideal' doctor could be defined as one having personal qualities for interpersonal relationships, technical skills and good intentions. However, doctors' opinions about what it means to be a 'good' patient have not been systematically investigated. Aim: To explore how patients define the characteristics of a 'good' and a 'bad' doctor, and how doctors define a 'good' and a 'bad' patient. Material and Methods: We surveyed a cohort of 107 consecutive patients attending a community teaching hospital in February 2019, who were asked to define the desirable characteristics of a good/bad doctor. Additionally, a cohort of 115 physicians working at the same hospital was asked to define the desirable characteristics of a good/bad patient. Responses were subjected to content analysis. Simultaneously, an algorithm in Python was used to automatically categorize responses throughout text-mining. Results: The predominant patients' perspective alluded to desirable personal qualities more importantly than proficiency in knowledge and technical skills. Doctors would be satisfied if patients manifested positive personality characteristics, were prone to avoid decisional and personal conflicts, had a high adherence to treatment, and trusted the doctor. The text-mining algorithm was accurate to classify individuals' opinions. Conclusions: Ideally, fusing the skills of the scientist to the reflective capabilities of the medical humanist will fulfill the archetype of what patients consider to be a 'good' doctor. Doctors' preferences reveal a "paternalistic" style, and his/her opinions should be managed carefully to avoid stigmatizing certain patients' behaviors.

Antecedentes: Desde la perspectiva del paciente, un médico "ideal" podría definirse como aquel que tiene cualidades para las relaciones interpersonales, habilidades técnicas y buenas intenciones. Sin embargo, las opiniones de los médicos sobre lo que significa ser un "buen" paciente no se han investigado sistemáticamente. Objetivo: Explorar cómo los pacientes definen las características de un "buen" y "mal" médico, y cómo los médicos definen un "buen" y "mal" paciente. Material y Métodos: Encuestamos a una cohorte de 107 pacientes consecutivos que asistieron a un hospital comunitario en febrero de 2019, a quienes se les pidió que definieran las características deseables de un médico bueno/malo. Además, se pidió a una cohorte de 115 médicos que trabajaban en el mismo hospital que definieran las características deseables de un paciente bueno/malo. Las respuestas se sometieron a un análisis de contenido. Simultáneamente, se utilizó un algoritmo en Python para clasificar automáticamente las respuestas mediante minería de texto. Resultados: Los pacientes aludieron que las cualidades personales del médico eran más importantes que la competencia en conocimiento y las habilidades técnicas. Los médicos estarían satisfechos si los pacientes mostraran características positivas de personalidad, fueran propensos a evitar conflictos, tuvieran una alta adherencia al tratamiento y confiaran en el médico. El algoritmo de minería de texto clasificó las opiniones de los encuestados en forma precisa. Conclusiones: Idealmente, fusionar las habilidades del científico con las capacidades reflexivas del médico humanista cumplirá con el arquetipo de lo que los pacientes consideran un "buen" médico. Las preferencias de los médicos revelan un estilo "paternalista", y sus opiniones deben manejarse con cuidado para evitar estigmatizar los comportamientos de ciertos pacientes.

Tuberculosis oral asociada al HIV: presentación de un caso clínico / HIV-related oral tuberculosis: report of a clinical case

La tuberculosis (TBC) es una enfermedad infecciosa causada principalmente por una bacteria, el Micobacterium tuberculosis. La estrecha vinculación entre TBC y VIH oermite hablar de una coepidemia dual. La localización oral de la TBC extrapulmon es rara, tanto en pacientes inmunocompetentes como VIH+. Las manifestaciones clínicas son inespecíficas, pudiendo presentarse como úlceras, fisuras, nódulos, granulomas o tumores. La falta de especificidad de las lesiones dificulta el diagnóstico. En este artículo se presenta un caso clínico de un paciente con TBC extrapulomonar en la cavidad oral asociado a HIV, atendido en el Servicio de Odontología del H.I.G.A. Gral. San Martín de la ciudad de La Plata.
