Proteomic analysis of dog tears for potential cancer markers

The first reference map of the proteome of pooled normal dog tears was created using 2-dimensional polyacrylamide gel electrophoresis and the identity of a number of the major species determined using matrix-assisted laser desorption time of flight mass spectrometry (MALDI-TOF) and peptide mass fingerprint matching on protein sequence databases. In order to understand the changes in protein expression in the tear film of dogs with cancer, tears from such animals were similarly examined. A number of differences were found between the tears of healthy dogs and the dogs with cancer. Differences were found in levels of actin and albumin and in an unidentified protein which may be analogous to human lacryglobulin. These findings suggest that it may be possible to develop tear film analysis to provide a simple non-invasive test for the diagnosis and/or management of canine cancers. (C) 2007 Elsevier Ltd.

Electromyographical, ultrasonographical and morphological modifications in semitendinous muscle after transposition as ventral perineal muscle flap

The aim of this study was to evaluate modifications occurring in semitendinous muscle after transposition as a ventral perineal muscle flap using electromyography, ultrasonography, and morphological studies. Ten male crossbreed dogs of 3-4 year old were used. The left semitendinous muscle was cut close to the popliteus lymph node, rotated and sutured at the perineal region. The contralateral muscle was considered as control. Motor nerve conduction studies of both sciatic-tibial nerves, and electromyographic and ultrasonographic examinations of both semitendinous muscles were performed before surgery and 15, 30, 60, and 90 days postoperatively. Semitendinous muscle samples were collected for morphological analysis 90 days after surgery. No alterations were observed in clinical gait examinations, or in goniometrical and electroneuromyographical studies in pelvic limbs after surgery. Electromyography demonstrated that the transposed muscle was able to contract, but atrophy was detected by ultrasonography and morphological analysis.

Correction of rectal sacculation through lateral resection in dogs with perineal hernia ? Technique description

The occurrence of perineal hernias in dogs during routine clinical surgery is frequent. The coexistence of rectal diseases that go undiagnosed or are not correctly treated can cause recurrence and postoperative complications. The objective of this report is to describe a surgical technique for treatment of rectal sacculation through lateral resection in dogs with perineal hernia, whereby restoring the rectal integrity.

Equine Perineal and Vulvar Conformation Correction Using a Modification of Pouret's Technique

An incompetent vulvar seal leads to reproductive failure, and a surgical intervention might be required. The present paper describes modifications to Pouret's surgery. We suggest the use of a simple interrupted vertical mattress suture, which avoids seroma. Eighteen Brazilian Jumping Horse mares, older than 20 years and barren for 3-5 consecutive years, underwent modified Pouret's surgery. A horizontal skin incision of 3-4 cm was made half way between the anus and upper commissure of the vulva. The submucosal and connective tissue were dissected, and the rectovaginal shelf was split horizontally by sectioning the muscular and ligamentous connections between the anus, vulva, caudal portion of the rectum, and vagina until the vulva was oriented vertically. The wound was changed from a horizontal plane to a vertical plane by placing the suture vertically using approximately eight interrupted U sutures distributed in two layers with polyamide thread. The modified Pouret's surgical technique provided a perfect coaptation of the vulvar lips and a correct perineal position. Those mares that presented with horizontally tipped vulvar lips due to advanced age and stretching of the pelvic tissues by multiple foaling had their vulvas replaced. Also, the surgical procedure was easy to perform. As to fertility, of the 18 initial mares, 14 were inseminated, and all became pregnant. Thus, it was possible to conclude that the anatomical changes performed throughout the surgical procedure predisposed to a better vulvar coaptation, correcting the pneumovagina. © 2013 Elsevier Inc.

Associação da catastrofização da dor com a incidência e a intensidade da dor perineal aguda e persistente após parto normal: estudo longitudinal tipo coorte

BACKGROUND AND OBJECTIVES: Vaginal birth delivery may result in acute and persistent perineal pain postpartum. This study evaluated the association between catastrophizing, a phenomenon of poor psychological adjustment to pain leading the individual to magnify the painful experience making it more intense, and the incidence and severity of perineal pain and its relationship to perineal trauma. METHOD: Cohort study conducted with pregnant women in labor. We used the pain catastrophizing scale during hospitalization and assessed the degree of perineal lesion and pain severity in the first 24 hours and after 8 weeks of delivery using a numerical pain scale. RESULTS: We evaluated 55 women, with acute pain reported by 69.1%, moderate/severe pain by 36.3%, and persistent pain by 14.5%. Catastrophizing mean score was 2.15 ± 1.24. Catastrophizing patients showed a 2.90 relative risk (RR) for perineal pain (95% CI: 1.08-7.75) and RR: 1.31 for developing persistent perineal pain (95% CI: 1.05-1.64). They also showed a RR: 2.2 for developing acute and severe perineal pain (95% CI: 1.11-4.33). CONCLUSIONS: The incidence of acute and persistent perineal pain after vaginal delivery is high. Catastrophizing pregnant women are at increased risk for developing acute and persistent perineal pain, as well as severe pain. Perineal trauma increased the risk of persistent perineal pain.

Ocorrência de Meloidogyne enterolobii em muricizeiro (Byrsonima cydoniifolia)

A entrada de agentes fitopatogênicos em novas localidades através de mudas infectadas constitui uma das principais formas de disseminação. Meloidogyne enterolobii é uma espécie de nematoide altamente virulenta que tem causado sérios danos a plantas cultivadas no Brasil. Neste trabalho é relatada a primeira ocorrência de M. enterolobii em mudas de muricizeiro (Byrsonima cydoniifolia), uma planta nativa da Amazônia e em mudas de goiabeira (Psidium guajava), no Estado de Mato Grosso. Com base nos caracteres morfológicos do padrão perineal de fêmeas, região labial dos machos e no fenótipo isoenzimático de esterase, foi confirmado que a espécie encontrada tanto nas mudas de muricizeiro quanto nas de goiabeira é M. enterolobii.

Anestesia subaracnóidea em crianças

JUSTIFICATIVA E OBJETIVOS: Tem aumentado muito o emprego da anestesia subaracnóidea em crianças, principalmente neonatos com risco de desenvolver apnéia neonatal. O objetivo deste trabalho foi rever as diferenças anatômicas, fisiológicas e farmacológicas desta técnica em crianças. CONTEÚDO: A anestesia subaracnóidea em crianças, apesar de ter sido técnica empregada desde o início do século XX, teve sua popularidade diminuída com o advento dos anestésicos inalatórios e bloqueadores neuromusculares, para ser novamente resgatada em 1979. As características favoráveis desta técnica em pediatria são relativas à estabilidade cardiovascular, em crianças de até 8 anos de idade, à analgesia satisfatória e ao relaxamento muscular. Os anestésicos mais utilizados em crianças são a tetracaína e a bupivacaína, cujas doses são ajustadas tomando-se por base o peso corporal. Esta técnica é limitada pela duração relativamente curta, devendo ser utilizada para procedimentos cirúrgicos que não ultrapassem 90 minutos e também pela analgesia não abranger o pós-operatório. As complicações são as mesmas encontradas no paciente adulto, incluindo cefaléia por punção dural e irritação radicular transitória. As indicações são várias: cirurgias de abdômen inferior, genitália, membros inferiores, região perineal e, em alguns casos, até em cirurgias torácicas. Seu emprego tem particular interesse nos recém-nascidos prematuros, pelo risco de apresentarem a apnéia da prematuridade. CONCLUSÕES: A anestesia subaracnóidea em crianças é técnica relativamente segura, com poucas complicações e pode ser considerada como opção para anestesia geral, principalmente nos recém-nascidos prematuros com risco de apresentarem complicações respiratórias no pós-operatório.

Rotura gástrica por barotrauma

Barogenic rupture of the stomach is a rare complication following cardiopulmonary resuscitation, administration of nasal oxygen by catheter and diving accidents. We report a case of gastric barotrauma following oroesophageal intubation. In most cases, the tears occur along the lesser curvature, what have been already attributed to Laplace's formula and, more recently, to morphological features of the stomach.

Resultado de partos domiciliares atendidos por enfermeiras de 2005 a 2009 em Florianópolis, SC

A cross-sectional study was performed to analyze obstetric and neonatal results of planned home births assisted by obstetric nurses in the city of Florianepolis, Southern Brazil. Data collected from the medical records of 100 parturient women cared for between 2005 and 2009 indicated 11 hospital transfers, nine of which underwent a Cesarean section. The majority of women who had a home birth showed normal fetal heart beat (94.0%) and progress on the partogram (61.0%), vertical water delivery was the position most frequently chosen (71.9%), newborns had an Apgar score >= 7 at five minutes (98.9%), episiotomy was performed in 1.0%, and 49.4% did not need perineal suturing. Outcomes indicated that planned home birth is safe.

Effect of intravaginal electrical stimulation on pelvic floor muscle strength

The aim of this study was to evaluate the effect of intravaginal electrical stimulation (IES) on pelvic floor muscle (PFM) strength in patients with mixed urinary incontinence (MUI). Between January 2001 and February 2002, 40 MUI women (mean age: 48 years) were studied. Urge incontinence was the predominant symptom; 92.5% also presented mild stress urinary incontinence (SUI). Selection criteria were clinical history and urodynamics. Pre-treatment urodynamic study showed no statistical differences between the groups. Ten percent of the women in each group had involuntary detrusor contractions. Patients were randomly distributed, in a double-blind study, into two groups. Group G 1 (n=20), effective IES, and group G2 (n=20), sham IES, with follow-up at 1 month. The following parameters were studied: (1) clinical questionnaire, (2) examiner's evaluation of perineal muscle strength, (3) objective evaluation of perineal muscle by perineometry, (4) vaginal weight test, and (5) urodynamic study. The IES protocol consisted of three 20-min sessions per week over a 7-week period using a Dualpex Uro 996 at 4 Hz. There was no statistically significant difference in the demographic data of both groups. The number of micturitions per 24 h after treatment was reduced significantly in both groups. Urge incontinence, present in all patients before treatment, was reduced to 15% in G1 and 31.5% in G2 post-treatment. The subjective evaluation of PFM strength demonstrated a significant improvement in G1. Objective evaluation of PFM force by perineometer showed a significant improvement in maximum peak contraction post-treatment in both groups. In the vaginal weight test, there was a significant increase in average number of cone retentions post-treatment in both groups. With regard to satisfaction level, after treatment, 80% of the patients in G1 and 65% of the patients in G2 were satisfied. There was no statistically significant difference between the groups. There was a significant improvement in PFM strength from both effective and sham electrostimulation, questioning the effectiveness of electrostimulation as a monotherapy in treating MUI.
