Clinical and radiographic changes of carpi, tarsi and interphalangeal joints of beef zebu bulls on semen collection regimen / Mudanças clínicas e radiográficas das articulações carpo, tarso e interfalangeana de touros de corte zebuínos em regime de colheita de sêmen

Osteoarthritis and osteochondrosis are highly correlated to reproductive failure in bulls. This study aimed to evaluate the carpal, tarsal and interphalangeal lesions in beef zebu bulls on semen collection regimen. Twenty-one beef cattle bulls, in a total of forty-one animals, were split into three age-based groups: animals from two to four years old (GI), from more than four to eight years old (GII) and above eight years old (GIII). The clinical findings were conformational changes of limbs, synovial effusion, peripheral venous engorgement of joints and prolonged decubitus. The total population showed moderate clinical manifestation and radiographic score. The GIII presented more severe joint lesions. Carpi and tarsi regions had discrete to difuse osteophytosis, subchondral cysts, cartilaginous flaps, bone incongruence and fragmentation, osteitis, and ankylosis. Interphalangeal joints presented osteophytosis, distal phalanx osteitis and enthesophytosis. The digital radiographic examination allowed full identification of articular lesions and their clinical correspondences, besides the positive correlation between age, body weight and radiographic score.(AU)

Osteoartrite e osteocondrose estão altamente correlacionados à falha reprodutiva em touros. Este estudo teve como objetivo avaliar as lesões do carpo, tarso e interfalangianas em touros zebuínos de corte em regime de coleta de sêmen. Vinte e um bovinos de corte, touros, provenientes de um total de 41 animais, foram divididos em três grupos baseados na idade, sendo eles: animais de dois a quatro anos (GI), de mais de quatro a oito anos (GII) e acima de oito anos de idade (GIII). Os sinais clínicos encontrados foram mudanças de conformação dos membros, derrame sinovial, ingurgitamento venoso periférico das articulações e decúbito prolongado. A população total avaliada apresentou manifestação clínica e escore radiográfico de grau moderado. Os touros mais velhos apresentaram maior gravidade nas lesões articulares. O GIII foi o que apresentou as lesões articulares mais severas. Identificou-se nos carpos osteofitose de discreta a difusa, cistos subcondrais, "flaps" cartilaginosos, fragmentação óssea, perda de congruência óssea, osteíte e anquilose; as lesões társicas obedeceram ao mesmo padrão. As articulações interfalangeanas apresentaram somente osteofitose, osteíte nas falanges distais e entesiofitose. O exame radiográfico digital permitiu a identificação completa das lesões articulares e suas correspondências clínicas, além da correlação positiva entre a idade, o peso corporal e o escore radiológico.(AU)

Estudo clínico, cirúrgico e anatomopatológico de intussuscepçäo em quatro bovinos / Clinical, surgical, and anatomopathologic study of four intussusception cases in cattle

Descrevem-se os achados clínico, cirúrgico e anatomopatológico de intussuscepçäo em quatro bovinos fêmeas. Observaram-se intussuscepçäo do jejuno, com obstruçäo total, em três animais, e intussuscepçäo do cólon, com obstruçäo parcial, em um animal. A presença de parasitismo intenso por Oesophagostomum sp. em dois animais sugere a participaçäo desse parasita na gênese da intussuscepçäo

[Bilateral tubal pregnancy with intrauterine device -- a case report]. / Gravidez tubaria bilateral em portadora de DIU -- relato de um caso.

PIP: Ectopic pregnancy occurs in Brazil in 1/300 cases. 99% are in the ovarian tubes and are almost always unilateral. The incidence rate for bilateral ectopic pregnancy has been described in literature to be 1/1,580 ectopic pregnancies. The article reports a case history at the maternity hospital of the Federal University in the Minas Gerais region. A 31 year-old leukodermatous patient in December 1980 began using an IUD (Lippes loop), followed by episodes of menorrhagia accompanied by abdominal colics of medium intensity during the following months. After the 3rd cycle menstrual delay occurred with abdominal pains localized mostly in the hypogastrium, but also in the lumbar and anal regions. After the diagnosis of ectopic pregnancy, the IUD was removed, resulting in minor bleeding a few days later. Subsequent ultrasonographic tests exposed a posterior pelvic tumorous mass at the uterus, 5.0x6.5 cm in diameter, and absence of uterine abnormalities, suggesting an ectopic pregnancy on the left. Following a complete physical examination including specular examination of the inner genitals it was decided to perform a diagnostic peritoneoscopy. It revealed an abdominal cavity presenting a large quantity of blood spread diffusely, uterus of normal size, and a cystic mass to the left+-6 cm in diameter apparently with hemorrhagic content. Laparotomy with transversal suprapubic incision was then performed. Final examinations indicated a bilateral tubal pregnancy ruptured on the left. The patient had a normal postoperative period and was discharged from the hospital after 6 days. Diagnosis is generally difficult since the unsuspected opposite tube may be infected and edematized due to bilateral endosalpingitis. For IUD users 2 etiological aspects of tubal pregnancies may be involved: Greater incidence rate of pelvic infection, modified tubal motility altering contractibility and possibly reversal of peristaltic wave. The necessity for examining both tubes when suspecting tubal pregnancy is stressed.^ieng
