Chronic Cases (chronic + case)
Selected AbstractsUterine torsion diagnosed in a mare at 515 days' gestationEQUINE VETERINARY EDUCATION, Issue 10 2010C. López Summary A pregnant mare with a history of prolonged gestation (,515 days) and suspected diagnosis of fetal mummification was examined. Rectal palpation revealed that the left broad ligament of the uterus was dorsal and medial to the right uterine ligament and it was not possible to observe the cervix during vaginal examination. Transabdominal ultrasound revealed fluid in the uterus, fetal membranes and the uterine walls defined and thickened. Free fluid was not seen in the peritoneal cavity. Laboratory tests (blood cell count and clinical chemistry) were normal. Based on clinical history, physical examination and ultrasound findings, a chronic uterine torsion with fetal death was diagnosed and the mare was subjected to exploratory celiotomy. The uterus was strongly adhered to the peritoneum of the ventral abdominal wall and there were multiple adhesions to the colon. Hysterotomy was performed to remove the fetus and to permit repositioning of the uterus. When the fetus was removed, a large devitalised grey tissue area of the right ventral uterine horn was observed. Multiple adhesions prevented a rescue hysterectomy and euthanasia of the patient was performed. During the necropsy, a 180° cranial cervix clockwise uterine torsion was observed. This rare case of uterine torsion appears to be the most chronic case reported in the equine literature. [source] Therapy of acute hepatitis CHEPATOLOGY, Issue S1 2002Professor Alfredo Alberti M.D. Acute hepatitis C has a high propensity to become chronic, which provides the rationale for treating patients with acute disease attempting to prevent chronicity. Almost all published studies on therapy of acute hepatitis C have been small in size, uncontrolled, and highly heterogeneous as to patient features, dose and duration of treatment, follow-up evaluation, and criteria used to define efficacy and safety. The published studies on treatment of acute hepatitis C have used standard alfa or beta interferon monotherapy: none have evaluated combination therapy of interferon and ribavirin or peginterferon. Several meta-analyses of published studies have concluded that initiation of interferon monotherapy during the acute phase of hepatitis C virus (HCV) infection significantly reduces (by 30% to 40%) evolution to chronic hepatitis. The tolerability of interferon in acute hepatitis C has been excellent, even in symptomatic and icteric patients; the side effects and adverse events being similar in type and frequency to those seen when treating chronic cases. Thus, currently available data support treatment of patients with acute hepatitis C, but data are insufficient to draw firm conclusions about which patients to treat, when therapy should be started, or what regimen is optimal. Future studies of adequate size and design should focus on efficacy and tolerability of peginterferons and whether therapy should be started immediately after diagnosis or delayed for 2 to 4 months to avoid treatment of patients who spontaneously recover.

Dobromylskyj Objectives: To investigate the correlation between the magnetic resonance imaging findings and subsequent surgical findings for a series of dogs presenting with suspected pharyngeal stick injuries to the Animal Health Trust, Newmarket, between 1995 and 2004. Methods: Magnetic resonance imaging findings were reviewed for patients undergoing a scan of the pharyngeal or cervical area for suspected foreign bodies during the years 1995 to 2004. Results: Case signalment, history and clinical signs were similar to those reported in previous studies. Magnetic resonance imaging demonstrated foreign material in six of seven cases where this was present. There was good correlation between diagnosis of a foreign body at magnetic resonance imaging and subsequent surgical identification. Clinical Significance: Compared with other imaging modalities, magnetic resonance imaging is very helpful for this type of injury, especially in chronic cases where radiographic evidence of a foreign body is unlikely. It is a valuable aid in the diagnosis of pharyngeal penetration injury and in surgical planning. [source] New insights into pediatric rhinosinusitisPEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 2007N. Principi Rhinosinusitis is a common children's disease. Most cases are acute, follow an episode of common cold, and are the consequence of a superimposed bacterial infection. If mild, they are characterized by the persistence of signs and symptoms of upper respiratory tract disease for more than 10 days; if severe, they involve fever and a purulent nasal discharge, and can cause a substantial decline in general health. Recurrent acute or chronic cases are usually diagnosed in children with predisposing factors, such as recurrent respiratory tract infections, allergic rhinitis, cystic fibrosis, immunodeficiency, ciliary dyskinesia, anatomic abnormalities or reflux. Therapy is based on antibiotics, administered orally in mild, and intravenously in severe cases. On the basis of recently highlighted antibiotic resistances and the possibility of spontaneous resolution, experts agree in considering amoxicillin the drug of choice for mild cases, and an antibiotic capable of overcoming all possible resistance for severe cases.
