RESUMOO objetivo deste estudo foi comparar a eficiência dos métodos radiográficos convencional e em distração de cães da raça Pastor Alemão adultos. Foram utilizados 16 animais, sendo onze fêmeas e oito machos, com idade média de quatro anos e dez meses. Todos os cães participantes foram avaliados clinicamente para se detectar a presença de alterações relacionadas ao aparelho locomotor e/ou sistema nervoso que afetariam a locomoção normal do cão, excluindo-se as alterações clínicas decorrentes do quadro de displasia coxofemoral (DCF

In the present study, 22 hip joints of Whippet (four), Rottweiler (five) and Labrador Retriever (two) young dogs were evaluated with the aim of comparing the ultrasonic examination of coxofemoral joints with the radiographic evaluations, both distraction and conventional procedures, for the early diagnosis of passive laxity. The study was based on static ultrasonography, conventional radiography (CR) and distraction radiography (DR) methods. In order to quantify the relationship between the femur head and the acetabulum, the alpha (alpha) and gamma (gamma) angles were measured by ultrasonographic examination, the Norberg angle (NA) was measured by CR, and the distraction index (DI) was measured by DR. It was observed a negative correlation between angles alpha and gamma (r= -0,756; P<0.001) and correlation between DI and NA (r= -0.474; P<0.026). No correlation was observed between angles alpha and gamma in relation to DI and NA (alpha and DI: r= -0.380; P<0.081; alpha and NA: r= 0.013; P<0.954; gamma and DI: r= 0.338; P<0.124; gamma and NA: r= -0.192; P<0.391). The static ultrasonographic did not prove to be a sensitive method to earlier detection of passive laxity of coxofemoral joints in dogs aging 14 and 15 day-old. The distraction index of DR was efficient in early detecting the passive laxity in dogs averaging five months old, when compared to the NA of CR. Two false negative dogs were detected by the DI. The CR method was relevant to detect osteoarthritis alterations, helping the diagnosis of hip dysplasia (HD).

RESUMO Avaliaram-se 160 radiografias das articulações coxofemorais de 40 cães de diferentes raças de grande porte, provenientes de Belo Horizonte, Brasil. As radiografias de cada animal foram obtidas em dois momentos: um (média de 7,23 meses de idade) e dois (média de 14,25 meses). Utilizaram-se o método radiográfico convencional (MRC) e o método radiográfico em distração (MRD), ambos realizados nos dois momentos. No MRC, mensurou-se o ângulo de Norberg (AN), o ângulo de inclinação (AI) e avaliouse a presença de doença articular degenerativa (DAD). O MRD foi realizado para se estabelecer o índice de distração (ID). Os objetivos foram avaliar a presença da linha Morgan (LM) e de outros sinais de DAD, correlacionando-os com o grau de displasia coxofemoral (DCF); além de se verificar se o ID maior que 0,3 (primeiro momento) possui associação com a presença de LM (segundo momento

Background: Retrograde endoscopic cholangiopancreatography (ERCP) effectively treats biliary and pancreatic disorders. Its indications are limited and precise, since its misuse delays adequate treatment, increases costs and to patient´s adverse events. Aim: To compare clinical, radiological and exploratory characteristics in relation to therapeutic success in patients undergoing ERCP in relation to age. Method: 421 patients who underwent the method were retrospectively studied; those who were not able to access the duodenal papilla were excluded. The patients were divided into two age groups: <60 years (group 1) and >60 years (group 2), and the variables of gender, examination indications, radiological findings, therapeutic success, diagnosis and the occurrence of immediate adverse events were analyzed. Results: 177 patients were allocated to group 1 and 235 to group 2. The main indication found in both groups was choledocholithiasis. In group 2, the number of cases of acute cholangitis (p=0.001), biliary stenosis (p=0.002) and papilla cancer (p=0.046) was higher. In this group, urgent indication for ERCP was higher (p=0.042), as well as the diagnosis of biliary tract dilatation (p<0.001). The placement of prostheses was the most common procedure performed in both groups, but the greatest number of patients in absolute quantity occurred in group 2. In group 1, the success in catheterization and the chance of achieving clearing of the biliary tract was significantly higher in compared to group 2 (p=0.016, OR=2.1). Conclusion: The success of catheterization and complete clearance of the bile duct was significantly higher in the group of young patients.
