Relação espacial entre a falange distal e o estojo córneo em éguas Campolinas jovens com e sem sinais de obesidade / Spatial relationship between the distal phalanx and the hoof capsule in young Campolina mares with and without obesity

Estudos prévios têm demonstrado alterações radiográficas em cascos de equinos obesos. Os objetivos foram estudar, com avaliação radiográfica, a relação espacial entre estojo córneo e falange distal de éguas jovens da raça Campolina com e sem obesidade. Foram utilizadas 22 éguas entre três e cinco anos de idade, sendo analisadas varáveis de adiposidade e medidas radiográficas dos cascos dos membros torácicos de éguas com escore corporal de 5 a 7/9 (Grupo Controle) e de 8 a 9 (Grupo Obeso). Foram feitas comparações entre os grupos e correlacionaram-se as variáveis de adiposidade entre si, variáveis adiposidade com variáveis casco e variáveis de casco entre si. Utilizou-se o teste t de Student para variáveis paramétricas e o teste Mann-Whitney para as não-paramétricas, para as medidas de correlação, utilizou o teste de Pearson para duas amostras paramétricas e o teste de Spearman para comparações que envolvam pelo menos uma variável não paramétrica (P<0,05). Os resultados demonstraram que éguas Campolinas obesas, ainda jovens, já apresentam indícios de alteração na relação espacial entre estojo córneo e falange distal.(AU)

Previous studies have demonstrated radiographic changes in the hoof of obese horses. The objective was to study through radiographic evaluation the spatial relationship between the hoof capsule and the distal phalanx of Campolina mares with and without obesity. Twenty-two Campolina mares 3 to 5 years old were used. We analyzed adiposity variables and radiographic measurements of the hoof of both forelimbs of mares with body condition score from 5 to 7/9 (Control group) and from 8 to 9 (Obese group). Comparisons were made between groups using the Student t test for parametric variables and the Mann-Whitney test for the nonparametric ones. Pearson or Spearman tests were used to evaluate the correlation among parametric and nonparametric variables respectively (P<0.05). Evidences of changes in the spatial relationship between the hoof capsule and the distal phalanx were observed in obese Campolina young mares.(AU)

A case of peripheral gangrene and osteomyelitis secondary to terlipressin therapy in advanced liver disease

Variceal bleeding and hepatorenal syndrome (HRS) are serious and life-threatening complications of advanced liver disease. Terlipressin is widely used to manage both acute variceal bleeding and HRS due to its potency and long duration of action. The most severe (though rare) adverse event is ischemia. The present report describes the case of a patient with gangrene and osteomyelitis secondary to terlipressin therapy. A 71-year-old male with alcoholic liver cirrhosis (Child-Pugh B) and chronic hepatitis C was admitted due to a drowsy mental status. The patient had several experiences of orthopedic surgery. His creatinine level had gradually elevated to 4.02 mg/dL, and his urine output decreased to 500 mL/24 hr. The patient was diagnosed as having grade III hepatic encephalopathy (HE) and type II HRS. Terlipressin and albumin were administered intravenously to treat the HRS over 11 days. Although he recovered from the HE and HRS, the patient developed peripheral gangrene and osteomyelitis in both feet. His right toes were cured with the aid of rescue therapy, but his left three toes had to be amputated. Peripheral gangrene and osteomyelitis secondary to terlipressin therapy occur only rarely, and there is no specific rescue therapy for these conditions. Thus, attention should be paid to the possibility of ischemia of the skin and bone during or after terlipressin therapy.
