RESUMO
BACKGROUND: Augmentation mastopexy focus on restoring the youthful appearance of the female breast. Despite those benefits, there is large scarring to be considered, and the reduction of this side effect is the main goal to enhance the aesthetic result. This article aims to describe a variation of the L-shaped mastopexy technique without complex marking and performed in planes, which brings long-term results for patients undergoing this approach. METHODS: This is a retrospective, observational study, based on a series of cases conducted by the author. The preoperative appointment and the surgical technique are described, and divided into steps according to their components: cutaneous, glandular tissue, and muscular. RESULTS: Between January 2016 and July 2021, 632 women underwent surgery. The mean age was 38 years (18-71 years). The mean volume of implants was 285cc (175-550cc). All the implants used were round with a nanotextured surface. The mean tissue resected from each breast was 117g (5-550g). Follow-ups ranged from 12 to 84 months, and photographic documentation was performed from 30 days after surgery. Complications totaled 19.30% and were divided into minor - treated with expectant treatment, non-invasive or with the possibility of correction with local anesthesia, corresponding to 10.44%; and major - in which it was necessary to return to the operating room, corresponding to 8.86%. CONCLUSION: Multiplane L-Scar Mastopexy is a versatile and safe technique with predictable results, which allows the systematic treatment of the most diverse breast types, with complications similar to other already described and solidified techniques.
RESUMO
Members of the family Diclidophoridae are potentially dangerous species for the puffer fish aquaculture worldwide. They are parasitic polyopisthocotyleans, with a posterior haptor equipped with clamps for attachment to the host's surface, allowing the worm to resist the flow of water to maintain its position on gills. The anterior body of the worm is deformable, allows the worm to feed on blood sucked from fish gills. The present study is the first description of a Heterobothrium species from the gills of the tiger puffer Lagocephalus sceleratus (Tetraodontidae) from the coasts of the Arabian Gulf at Jubail, Saudi Arabia morphologically by light microscopy as well as by molecular analysis of the parasite partial 28S rRNA through multiple sequence alignments and phylogeny by maximum likelihood analysis which is provided for the first time for the described species. Seventeen tiger puffer fish were captured alive from marine water off Saudi Arabia; gills were separated and further examined for parasitic infection. Nine fish were found infected with a monogenean parasite which was robust, equipped by two buccal organs at the tapered anterior end; the posterior haptor was rectangular with four symmetrically arranged clamps, with no isthmus. Marginal hooks absent. Ovary elongated, U-shaped, testes numerous, irregularly shaped and extended from the posterior part of the ovary to the anterior margin of the haptor. Copulatory organ muscular, as a spherical cup armed with 12 to 15 genital hooks. The molecular analysis of the parasite 28s rRNA and phylogeny revealed a percentage of identities between 87.47-89.09%, with Diclidophoridae species within the monophyletic clade of Mazocraeidea where a maximum percentage of 89.09% were obtained for the morphologically different sister taxon H. okamotoi. The results obtained from molecular analysis are consistent with the conclusions drawn from morphological classification where that the parasite recorded was morphologically similar to H. lamothei which was not characterized by molecular analysis before. The recovered sequences were deposited into the GeneBank under accession number MT322610.(AU)
Os membros da família Diclidophoridae são espécies potencialmente perigosas para a aquicultura de peixes puffer em todo o mundo. Eles são parasitas poliopisthocotyleans, com uma hélice posterior equipada com pinças para fixação na superfície do hospedeiro, permitindo que o verme resista ao fluxo de água para manter sua posição nas brânquias. O corpo anterior do verme é deformável, e permite que o verme se alimente de sangue sugado das guelras dos peixes. O presente estudo é a primeira descrição de uma espécie Heterobothrium das guelras do tigre Lagocephalus sceleratus (Tetraodontidae) das costas do Golfo Arábico em Jubail, Arábia Saudita, usando morfologia por microscopia leve, bem como análise molecular do rRNA parcial do parasita 28S através de alinhamentos de sequências múltiplas e filogenia por análise de máxima verossimilhança que é fornecida pela primeira vez para as espécies descritas. Dezessete peixes tigre puffer foram capturados vivos da água marinha da Arábia Saudita; as brânquias foram separadas e mais tarde examinadas para detecção de infecção parasitária. Nove peixes foram encontrados infectados por um parasita monogênio robusto, equipado por dois órgãos bucais na extremidade anterior afilada; o hortetor posterior era retangular com quatro pinças dispostas simetricamente, sem istmo. Ausência de ganchos marginais. Ovário alongado, em forma de U, testículos numerosos, de forma irregular e estendido desde a parte posterior do ovário até a margem anterior do hortelino. Órgão copulatório muscular, como um copo esférico armado com 12 a 15 ganchos genitais. A análise molecular do parasita 28s rRNA e filogenia revelou uma porcentagem de identidades entre 87,47-89,09%, com espécies Diclidophoridae dentro do clade monofilético de Mazocraeidea onde uma porcentagem máxima de 89,09% foi obtida para o táxon-irmão morfologicamente diferente H. okamotoi. Os resultados obtidos da análise molecular são consistentes com as conclusões tiradas da classificação morfológica onde o parasita registrado era morfologicamente semelhante ao H. lamothei que não era caracterizado pela análise molecular antes. As sequências recuperadas foram depositadas no GeneBank sob o número de acesso MT322610.(AU)

RESUMO
Position and source of blood supply to the human carotid body displays population variations. These data are important during surgical procedures and diagnostic imaging in the neck but are only scarcely reported and altogether missing for the Kenyan population. The aim of this study was to describe the position and blood supply of the carotid body in a Kenyan population. A descriptive cross-sectional study at the Department of Human Anatomy, University of Nairobi, was designed. 136 common carotid arteries and their bifurcations were exposed by gross dissection. The carotid body was identified as a small oval structure embedded in the blood vessel adventitia. Position and source of blood supply were photographed. Data are presented by tables and macrographs. 138 carotid bodies were identified. Commonest position was carotid bifurcation (75.4 percent) followed by external carotid artery (10.2 percent), internal carotid artery (7.2 percent) and ascending pharyngeal artery (7.2 percent). Sources of arterial blood supply included the carotid bifurcation (51.4 percent), ascending pharyngeal (21.0 percent), external carotid (17.4 percent) and internal carotid (10.2 percent) arteries. Position and blood supply of the carotid body in the Kenyan population displays a different profile of variations from those described in other populations. Neck surgeons should be aware of these to avoid inadvertent injury.
La posición y la fuente de suministro sanguíneo del cuerpo carotídeo humano muestra variaciones en la población. Estos datos son importantes durante los procedimientos quirúrgicos y de diagnóstico por imagen en el cuello, pero son poco informados e inclusive faltan por completo en la población de Kenia. El objetivo de este estudio fue describir la posición y el aporte sanguíneo del cuerpo carotídeo en una población de Kenia. Se diseñó un estudio descriptivo de corte transversal en el Departamento de Anatomía Humana de la Universidad de Nairobi. 136 arterias carótidas comunes y sus bifurcaciones fueron expuestas mediante disección simple. El cuerpo carotídeo fue identificado como una pequeña estructura oval ubicada en la adventicia del vaso sanguíneo. La posición y la fuente de suministro sanguíneo fueron fotografiados. Los datos obtenidos fueron presentados en las tablas y fotomacrografías. 138 cuerpos carotídeos fueron identificados. La posición más frecuente fue la bifurcación carotídea (75,4 por ciento), seguida de la arteria carótida externa (10,2 por ciento), arteria carótida interna (7,2 por ciento) y la arteria faríngea ascendente (7,2 por ciento). Las fuentes de suministro sanguíneo arterial incluyeron la bifurcación carotídea (51,4 por ciento), arteria faríngea ascendente (21,0 por ciento), arteria carótida externa (17,4 por ciento) y arterias carótidas internas (10,2 por ciento). La posición y el suministro sanguíneo del cuerpo carotídeo en la población de Kenia muestra un perfil de variaciones diferente a las descritos en otras poblaciones. Los cirujanos de cuello deben conocer estas variaciones para así evitar lesiones accidentales.
