Adenocarcinoma gástrico T4b: experiência de 12 anos em Hospital Universitário

A neoplasia gástrica é doença heterogênea e multifatorial, com incidência e mortalidade variando geograficamente. Aproximadamente 60% dos diagnósticos em pacientes de países ocidentais ocorrem nos estádios III ou IV. Nestes doentes, o melhor tratamento consiste na realização de procedimento cirúrgico. OBJETIVO: Identificar os aspectos epidemiológicos de pacientes diagnosticados com adenocarcinoma gástrico T4b. MÉTODOS: Estudo observacional, transversal, retrospectivo, de fonte secundária, dos pacientes diagnosticados com adenocarcinoma gástrico T4b através de estadiamento patológico. Foram analisados 815 prontuários, sendo 27 pacientes estudados. As variáveis investigadas foram: aspectos demográficos, principais queixas, fatores de risco, acesso ao serviço de saúde, aspectos cirúrgicos, morbidade, mortalidade e sobrevida. RESULTADOS: Vinte e dois eram homens (81,5%) e cinco mulheres (18,5%) com idade variando de 38 a 87 e média de 58,78 anos. O tempo de acesso ao serviço, em meses, variou de 1 a 120, com média de 12,5. Os sinais e sintomas mais prevalentes foram: perda de peso 23 (85,2%), epigastralgia 22 (81,5%), vômitos 16 (59,3%) e plenitude gástrica 12 (44,4%). A frequência de acometimento das estruturas adjacentes foi: pâncreas oito (29,6%), fígado sete (25,9%), cólon transverso seis (22,2%), intestino delgado seis (22,2%), mesocólon três (11,1%), baço um (3,7%) e vesícula biliar um (3,7%). Morbidades pós-operatórias ocorreram em 51,85% dos pacientes. Houve associação significativa entre mortalidade cirúrgica e ocorrência de fístula/deiscência, choque séptico e sangramento. A sobrevida ao final de seis meses foi de 63,27%. CONCLUSÃO: A média do tempo entre início dos sintomas e acesso ao serviço de saúde especializado foi elevada. Mais da metade dos pacientes apresentaram morbidades pós-operatórias. Os pacientes que apresentaram fístula/deiscência, sangramentos e choque séptico tiveram associação significativa com mortalidade cirúrgica. A sobrevida ao final de seis meses foi de 63,27%.

Alloxan diabetes alters the tensile strength, morphological and morphometric parameters of abdominal wall healing in rats

PURPOSE:To investigate the effects of alloxan diabetes on the abdominal wall healing of rats undergoing laparotomy.METHODS:Ninety-six male Wistar rats weighing between 200 and 300 grams, divided into two groups: non-diabetic group (G1) and another with untreated diabetes (G2). Three months after diabetes induction, the animals underwent a 5cm-long- laparotomy and 5.0 nylon monofilament suture. After the surgery, 12 animals from each group were euthanized on days 4, 14, 21 and 30 corresponding to the moments M1, M2, M3 and M4. In each moment a fragment of the abdominal wall containing the scar was removed for tensile strength measurement, histological and morphometric study. Clinical and biochemical parameters were also analyzed.RESULTS:G2 animals showed parameters compatible with severe diabetes and decreased plasma levels of insulin. The tensile strength in G2 was significantly smaller in M2 and M4, with a tendency to fall in the other two. Through light microscope, diabetic animals showed more difficulty to increase collagen density and contraction. G2 animals showed high cellularity of fibroblasts in later healing moments, with collagen thinning in M2 and M4.CONCLUSION:The abdominal wound healing in untreated diabetic animals was altered and led to a higher incidence of dehiscence and infections.

MANAGEMENT OF A CARAPACE FRACTURE IN A SIX-BANDED ARMADILLO (EUPHRACTUS SEXCINCTUS)

An adult female free-ranging six-banded armadillo (Euphractus sexcinctus) was presented with an inverted L-shaped fracture of the left pectoral carapace. The fracture was stabilized with the use of three simple interrupted interfragmentary sutures of 2-0 nylon. After 7 days, wound dehiscence occurred, so sutures were replaced and the wound treated topically with castor bean oil cream. Healing of the fracture was observed after 14 days of this treatment.

Two-stage rumenostomy in buffaloes

Background: Rumenostomy may be performed for therapeutic and digestibility research purposes in bovines, small ruminants and camelids. Several studies requires romenostomy in buffaloes in order to sample ruminal content for laboratorial assays. However, complications and outcome of rumenostomy was poorly studied in buffaloes. Therefore, the aim of the current study was to describe a two-stage rumenostomy technique in buffaloes, focused on intra and post-operative period.Materials, Methods & Results: Nine Murrah buffaloes were submitted to a 36-h and 12-h of food and water fastening. The animals were given acepromazine and maintained in standing position. Flank local anesthesia was carried out. A circular skin incision was carried out in the center of the left flank, followed by divulsion of the external and internal obliques and transversus abdominus muscles, and incision of the peritoneum. Subsequently, a segment of the dorsal aspect of the rumen was grasped and pulled through the flank incision. The rumen was attached to the peritoneum and skin incision margins in four points (dorsal, ventral, cranial and caudal). Additional simple interrupted sutures attaching the rumen serosa to the skin were applied subsequently. Four additional interrupted horizontal mattress sutures were applied equidistantly, taking bites only in the skin and rumen serosa. Following 12 h, the second stage was carried out. The buffaloes were prepared and restrained as performed for the first stage. A circular flap was excised from the exteriorized rumen and the silicone romenostomy cannula was placed. Clinical parameters, postoperative recovery, weight and behavioral pain scale were assessed. Positioning and anesthesia regimen were adequate for the achievement of the procedure. However, two animals fell in the restraint chute during the first surgical stage. Mild ischemia of the exteriorized rumen segment was observed on the second surgical stage, which resulted in less hemorrhage and enhanced cannula positioning. Complete cicatrization and permanent adhesion of the rumen to the skin were achieved. No ruminal leakage to the abdominal cavity occurred. No signs of pain were reported. There were few cases of laxity of the romenostomy opening leading to drop of cannula, myiasis on the margin of the stoma site and few cases of mild ruminal content leakage on the long-term assessment.Discussion: Restraint in standing position was considered adequate, although lateral recumbence constitutes another option. However, higher risk of contamination and technical difficulties in placing the cannulas are expected if lateral recumbence is considered. In other trials using acepromazine, no accidental recumbence occurred. Xylazine was also indicated for chemical restraint of buffaloes. It is known that flexible cannulas provide better anatomic adjustment and adaptation as well as being effective for sampling ruminal content, as seen in the current study. Ruminal leakage is one of the most frequent complications of romenostomy, which may affect animal's welfare. The animals in the current study presented no variations on the body score, even though on those presenting cannula loosening or ruminal content leakage. Moreover, no significant changes of the ruminal content parameters were noticed. Myiasis was also reported following ruminal surgical interventions, which were mainly attributed to extensive breeding. Loss of the cannula, subcutaneous emphysema and suture dehiscence are common complications of romenostomy. Nonetheless, none of those complications were found on the current study. Thus, romenostomy was feasible and efficient for sampling and performing assays of the ruminal content in buffaloes.

Uma atividade de educação em saúde para puérperas num alojamento conjunto

The Rooming favors the permanence of the mother with the newborn, thus establishing a stronger link between the mother and baby, in addition, care assistance and guidance are essential to both through the health care team because they recognize the moments critical that their interventions are necessary to ensure the health of both. The educational lecture was an option to have the opportunity to assist, guide and answer possible questions that may arise for mothers, and also to assess the knowledge of puéperas regarding the care of babies and self care. There was participation from 40 patients. In the study methodology was developed a questionnaire containing two subjects (self-care and care for newborns) was given to patients before and after the lecture held by the author in a rooming Maternity HC de Botucatu. The results were analyzed statistically and studied by the author, allowing note that many significant results were obtained after the lecture, which we realize that the same intervention on self-care was significant in respect of: bleeding, infection in the genital tract and urinary tract, surgical dehiscence , care of the lower limbs and constipation, how to care for the newborn was the significance to the questions about the hygiene of the umbilical stump, cramps, hunger, weeping and pacifiers. In the pre-lecture questions 73.00% of 27.00% were right and wrong. Our conclusion is that the mothers have a high level of prior knowledge and educational lectures enriches their knowledge in a creative and participatory

Double-setting alpha-tricalcium phosphate cement provided with interconection channels in rabbits after enucleation: a potential implant for the anophthalmic socket

The purpose of this study was to evaluate the macroscopy and microstructure of a double setting alpha-tricalcium phosphate bone cement sphere provided with interconnection channels (alpha-TCP-i), as well as the integration of the implant with the rabbits' orbital tissue, through macroscopic analysis and histopathology. The external and internal surfaces of the alpha-TCP-i were evaluated macroscopically and by electron microscopy. Twelve New Zealand rabbits received 12mm implants of alpha-TCP-i following enucleation of the left eye. The clinical assessment was undertaken daily during the first 15 days, followed by fortnightly assessment until the end of the study period. For the morphological analysis, exenteration was performed in 3 animals per experimental period (15, 45, 90 and 180 days). The external and internal surfaces of the implant appeared solid, smooth and compact, with six channels which interconnected centrally. The micro-architecture was characterized by the formation of columns of hexagonal crystals. No signs of infection, exposure, dehiscence of sutures or extrusion of the implant were noted in any of the animals during the entire period of the study. The morphological evaluation demonstrated the presence of a thin capsule around the implant, from whence appeared fibro-vascular projections, which penetrated it through the interconnecting channels. In the first days after the insertion of the implant, an intense inflammatory reaction was noted. At 180 days, however, there were no signs of inflammation. The alpha-tricalcium phosphate cement implant was well tolerated in this rabbit model and appeared to be relatively inert with some fibrovascular ingrowth through the large channels.
