Atresia anal, fístula uretrorretal congênita, bolsa escrotal acessória e pseudo-hermafroditismo em bezerro mestiço

Neste trabalho, é descrito o caso de um bezerro mestiço recém-nascido que apresentava atresia anal tipo 2, fístula uretrorretal congênita, bolsa escrotal bífida e pseudo-hermafroditismo masculino. O principal sinal clínico era a eliminação de fezes por meio do óstio prepucial, uma apresentação incomum em casos de fístula uretrorretal em animais machos. Apesar de o quadro de atresia anal ser relativamente comum nessa espécie, os outros defeitos congênitos encontrados são pouco frequentes.

Long-term results of operative treatment for Hirschsprung's disease and internal anal sphincter achalasia

The aim of the study was to evaluate long-term results of operative treatment for Hirschsprung's disease(HD) and internal anal sphincter achalasia. Fecal continence and quality of life were evaluated by a questionnaire in 100 adult patients who had undergone surgery for HD, during 1950-75. Fecal continence was evaluated using a numerical scoring described by Holschneider. Fifty-four of the 100 patients underwent clinical examination, rigid sigmoidoscopy and manometric evaluation. In anorectal manometry basal resting pressure(BRP)and maximal squeeze pressure(MSP) were measured and voluntary sphincter force(VSF) was calculated by subtracting the BRP from MSP. The results of operative treatment for adult HD were compared with the results of the patients operated in childhood. In adult HD the symptoms are such mild that the patients attain adolescence or even adulthood. The patients with HD and cartilage-hair-hypoplasia were specifically evaluated. The outcome of the patients with internal anal sphincter achalasia operated on by myectomy was evaluated by a questionnaire and continence was evaluated using a numerical scoring described by Holschneider. Of the 100 patients operated on for HD 38 patients had completely normal bowel habits. A normal or good continence score was found in 91 our of 100 patients. Nine patients had fair continence. One of the patients with fair continence had Down's syndrome and two were mentally retarded for other reasons. Only one patient suffered from constipation. In anorectal manometry the difference in BRP between patients with normal and good continence was statistically significant, whereas the difference between good and fair continence groups was not statistically significant. The differences on MSP and VSF between patient groups with different continence outcome were not statistically significant. The differences between patient groups and normal controls were statistically significant in BRP and MSP. In VSF there was not statistically significant difference between the patients and the normal controls. The VSF reflects the working power of the muscles including external sphincter, levator ani and gluteal muscles. The patients operated at adult age had as good continence as patients operated in childhood. The patients with HD and cartilage-hair-hypoplasia had much more morbidity and mortality than non-cartilage-hair-hypoplasia HD patients. The mortality was as high as 38%. In patients with internal anal sphincter achalasia the constipation was cured or alleviated by myectomy whereas a significant number suffered from soiling-related social problems.

Age and growth of the swordfish (Xiphias gladius L.) in the waters around Taiwan determined from anal-fin rays

Age and growth of the swordfish (Xiphias gladius) in Taiwan waters was studied from counts of growth bands on cross sections of the second ray of the first anal fin. Data on lower jaw fork length and weight, and samples of the anal fin of male and female swordfish were collected from three offshore and coastal tuna longline fishing ports on a monthly basis between September 1997 and March 1999. In total, 685 anal fins were collected and 627 of them (293 males and 334 females) were aged successfully. The lower jaw fork lengths of the aged individuals ranged from 83.4 to 246.6 cm for the females and from 83.3 to 206 cm for the males. The radii of the fin rays and growth bands on the cross sections were measured under a dissecting microscope equipped with an image analysis system. Trends in the monthly marginal increment ratio indicated that growth bands formed once a year. Thus, the age of each fish was deter-mined from the number of visible growth bands. Two methods were used to estimate and compare the standard and the generalized von Bertalanffy growth parameters for both males and females. The nonlinear least square estimates of the generalized von Bertalanffy growth parameters in method II, in which a power function was used to describe the relationship between ray radius and LJFL, were recommended as most acceptable. There were significant differences in growth parameters between males and females. The growth parameters estimated for females were the following: asymptotic length (L∞) = 300.66 cm, growth coefficient (K) = 0.040/yr, age at zero length (t0) = –0.75 yr, and the fitted fourth parameter (m) = –0.785. The growth parameters estimated for males were the following: asymptotic length (L∞) = 213.05 cm, growth coefficient (K) = 0.086/yr, age at zero length (t0) = –0.626 yr, and the fitted fourth parameter (m) = –0.768.

Anchorage of air bladder with the interspinous bone of the anal fin in Lactarius lactarius (Bloch and Schneider, 1801)

Specimens of the false trevally (Lactarius lactarius ), 127 to 221 mm in total length, were studied for the mode of anchorage of the air-bladder with the interspinous bone of the anal fin. The 1st and 2nd interspinous bones are fused together into a single piece (named here as the anchor bone) which pierces through the air-bladder, dividing it into two intercommunicating chambers at its upper end, and ultimately articulates with the 10th vertebral bone. The lower end of the bone is broad, fan like with one side affording articulation with the 1st and 2nd anal spines. This is an unique feature of great taxonomical importance to L. lactarius, the only species in the family Lactariidae. The anal fin counts (23-27) and vertebral counts (23) are also given.

Anal redness in European eels as an indicator of infection by the swimbladder nematode, Anguillicola crassus

Anal redness in European eels Anguilla anguilla is related to the prevalence and mean abundance of the swimbladder nematode Anguillicola crassus and may provide a simple. non-invasive diagnostic tool for A. crassus infection. (C) 2003 The Fisheries Society of the British Isles.

Pelvic floor dysfunction 6 years post-anal sphincter tear at the time of vaginal delivery.

INTRODUCTION AND HYPOTHESIS: This study aims to estimate fecal, urinary incontinence, and sexual function 6 years after an obstetrical anal sphincter tear. METHODS: Among 13,213 women who had a vaginal delivery of a cephalic singleton at term, 196 women sustained an anal sphincter tear. They were matched to 588 controls. Validated questionnaires grading fecal and urinary incontinence, and sexual dysfunction were completed by the participants. RESULTS: Severe fecal incontinence was more frequently reported by women who had sustained an anal sphincter tear compared to the controls. Women with an anal sphincter tear had no increased risk of urinary incontinence, but reported significantly more pain, difficulty with vaginal lubrication, and difficulty achieving orgasm compared to the controls. A fetal occiput posterior position during childbirth was an independent risk factor for both severe urinary incontinence and severe sexual dysfunction. CONCLUSIONS: Fecal incontinence is strongly associated with an anal sphincter tear. A fetal occiput posterior position represents a risk factor for urinary incontinence and sexual dysfunction.

Could concomitant radio-chemotherapy improve the outcomes of early-stage node negative anal canal cancer patients? A retrospective analysis of 122 patients.

One hundred twenty-two early-stage anal canal cancer patients (median age: 69 years) were treated with curative radiotherapy with (70 patients) or without (52 patients) concomitant chemotherapy. Median follow-up was 65 months (range: 4-238). At multivariate analysis, concomitant chemotherapy significantly improved local control (p = .007). Local control significantly influenced all considered endpoints, except the metastases free survival. The global rates of G3-G4 acute and late toxicity were 13.1% and 8.2%, respectively, and they were not increased by concomitant chemotherapy. Finally, concomitant chemotherapy is efficacious and safe in the treatment of T1-2N0 anal canal cancer patients and should be prospectively studied.

Utilidad de la electromiografía de esfínter anal en el diagnóstico diferencial de la atrofia multisistémica: una revisión de la literatura

La atrofia multisistémica (AMS) es una enfermedad degenerativa caracterizada por disautonomías y síntomas extrapiramidales. El diagnóstico diferencial con otros parkinsonismos es difícil, por lo cual se requiere una ayuda paraclínica para soportar el diagnóstico clínico. La degeneración del núcleo de Onuf, exclusiva en esta enfermedad, podría sugerir que la presencia de denervación en el esfínter anal podría ser tomada en cuenta como criterio diagnóstico de AMS. Se realizó una revisión sistemática con el fin de determinar la utilidad de la electromiografía de esfínter anal (EMG-EA) en el diagnóstico diferencial de AMS contra otros parkinsonismos. Se incluyeron 17 estudios que analizaron los resultados de EMG-EA en pacientes con AMS. De éstos, 11 de estudios fueron analíticos y compararon pacientes con AMS y otros parkinsonismos. Los 6 estudios restantes fueron descriptivos. La duración de los potenciales de unidad motora (PUM) es significativamente mayor en pacientes con AMS comparados con otros parkinsonismos, y utilizando un punto de corte > 13 ms muestra características operativas que hacen a este parámetro potencialmente útil. Solo un estudio encontró diferencias significativas en el porcentaje de PUM polifásicos, el cual tuvo una sensibilidad y especificidad clínicamente útil cuando el punto de corte es mayor a 60%. El resto de los estudios no reportan diferencias estadísticamente significativas entre parkinsonismos. La literatura disponible apunta a la potencial utilidad de la EMG-EA en el diagnóstico diferencial de la AMS de otros parkinsonismos; sin embargo es necesario conducir más estudios para solventar las limitaciones metodológicas existentes.
