RESUMO - RACIONAL: O sucesso da diálise peritoneal depende da implantação adequada e da longevidade funcional do cateter. O implante laparoscópico através da tunelização na bainha do reto abdominal minimiza os riscos de disfunção do cateter. OBJETIVOS: Descrever técnica simplificada com portal único para o implante laparoscópico de cateter de diálise peritoneal com tunelização na bainha do reto abdominal. MÉTODOS: Utilizou-se inserção laparoscópica de cateter de Tenckhoff com tunelização da bainha do reto em 16 pacientes com insuficiência renal crônica. RESULTADOS: Durante o período de acompanhamento não ocorreram complicações relacionadas ao procedimento. Três pacientes foram excluídos: um foi encaminhado para transplante renal algumas semanas após o implante e outro faleceu por outro motivo durante o acompanhamento. Um terceiro necessitou de lise de aderências devido à operação anterior, portanto foi necessário um portal adicional. Os outros 13 pacientes apresentaram bom funcionamento do cateter. Não houve hemorragia pós-operatória, vazamentos, hérnia ou migração do cateter. Um paciente teve infecção no túnel subcutâneo 11 meses após o implante. Não foi observada peritonite durante o período de acompanhamento. CONCLUSÕES: A técnica é simples, reprodutível, segura, com bons resultados de funcionalidade, poucas complicações e alta taxa de sobrevida do cateter. Ela não requer trocarte especial e evita o uso excessivo de portais.

ABSTRACT - BACKGROUND: The success of peritoneal dialysis depends on the proper placement and functional longevity of the dialysis catheter. Laparoscopic implantation of a catheter through a rectus sheath tunneling can minimize the risks of catheter failure. AIMS: This study aims to describe one-port simplified technique for laparoscopic placement of a peritoneal dialysis catheter with rectus sheath tunneling. METHODS: The simplified laparoscopic insertion of a Tenckhoff catheter with rectus sheath tunneling was performed in 16 patients with chronic renal failure. RESULTS: During the follow-up period, no major complications occurred. Three patients were excluded. One was referred to the renal transplant some weeks after implantation, and one died for other reasons during the follow-up. Another patient needed adhesiolysis due to previous surgery, so an additional port was necessary. The other 13 catheters worked properly, and no postoperative hemorrhage, early leaks, hernia, or catheter migration occurred. One patient had a tunnel infection 11 months after the implant. No peritonitis was observed during the follow-up. CONCLUSIONS: The technique is simple, reproducible, and safe, with good results in catheter function, few complications, and a high catheter survival rate. It does not require a special device or trocar and avoids excessive port sites.

Phytochemical investigation of the leaf extracts from Miconia ferruginata (Melastomataceae) led to the isolation and characterization of the flavonoids 5,6,7-trihydroxy-4'-methoxyflavone, 5-hydroxy-7,4'-dimethoxy-8-methylflavone and 5,7,4'-trihydroxy-6,8-dimetilflavone, triterpenes ursolic acid and oleanolic acid, in addition to the steroids β-sitosterol and stigmasterol. The structures of these compounds were proposed by spectroscopic analysis and comparison with literature data. This paper also describes the insecticidal effects of leaf extracts from M. ferruginata to one of the main pests of maize, the fall armyworm (Spodoptera frugiperda). The ingestion bioassays, the leaf extracts showed an elongation of the larval stage of 16.56 days as compared to the control.

Abstract We present a case of a 41-year-old female with deep vein thrombosis after abdominal surgery. The patient quickly developed severe pulmonary embolism and stroke representative of paradoxical embolism. Echocardiography showed a thrombus straddling a patent foramen ovale, which was confirmed intraoperatively. An accurate diagnosis and rapid treatment decisions are crucial for preventing patient deterioration in the form of new pulmonary embolisms or stroke.

Descreve-se uma família com síndrome dos cabelos anágenos frouxos (SCAF) associada à distrofia macular. Foram descritos os achados dermatológicos, oftalmológicos e de microscopia óptica e eletrônica de varredura de 11 indivíduos. Dois apresentaram SCAF, sem qualquer alteração ocular. Dos quatro indivíduos com alteração ocular, duas irmãs apresentaram SCAF e dispersões pigmentares em pólo posterior da retina, com coloboma da mácula. Em dois irmãos encontraram-se as mesmas características da SCAF e fundo de olho com dispersões pigmentares em pólo posterior, sem coloboma. Os achados sugerem que essa associação seja uma nova entidade nosológica dentro das displasias ectodérmicas.

The article describes a family with loose anagen hair syndrome (LAHS) associated with macular dystrophy. Complete dermatological and ophthalmological exams, and hair examination under optical and electron microscopy were performed in eleven index cases. Two individuals demonstrated hair findings with LAHS without ocular problems. Within the four cases with ocular problems, two sisters presented with LAHS and pigmentary dispersion on the retina with macular coloboma. Two brothers presented with LAHS and pigmentary dispersion on the retina without macular coloboma. The findings suggest that this new association is a disorder among the ectodermal dysplasia.
