The disease is characterised by clinical signs of the upper respiratory tract, such as a (muco)purulent nasal discharge, hyperaemia of the muzzle (red nose disease) and by conjunctivitis. Signs of general illness are fever, depression, inappetence, abortions and reduced milk yield. The virus can also infect the genital tract and cause pustular vulvovaginitis and balanoposthitis. Postmortem exam...

Dysphagia is not uncommon in gastroenterology practice. The differential diagnosis is wide and includes both mechanical and motility causes. Esophageal lichen planus is uncommon but now increasingly recognized. It occurs in more than half of cases of lichen planus with muco-cutaneous involvement. Often there is a delay in diagnosis and subsequent treatment. The endoscopic picture of esophageal ...

IN cystic fibrosis the main problem is the susceptibility of the children to respiratory infection. The clinical course of the untreated case is one of repeated respiratory infections followed by persistent pulmonary sepsis, and later death. Severe attacks may occur in the first weeks or months of life, or less commonly, years may pass with no, or minimal symptoms referable to the chest. Upper ...

Introduction: Malignant parotid tumors are rare. They are characterized by their histological diversity dominated by muco-epidermoid tumors and adenocarcinomas; squamous cell carcinomas are much rarer. Result: We report a case of carcinoma not very differentiated from the parotid evolving for 6 years to reach 15 cm of major axis at the time of its diagnosis in a 35-year-old woman. Conclusion: E...

Multicentric reticulohistiocytosis (MRH) is a rare systemic disease, which commonly manifests as muco-cutaneous papulonodules and inflammatory erosive polyarthropathy. In this research, we report the clinical manifestations and management of a rare case of MRH with destructive arthropathy of bilateral hip joints and arthritis mutilans presenting with characteristic deformities. Disabling hip ar...

A new mathematical model of the transport of mucus and periciliary liquid (PCL) in the airways by cilia is presented. Mucus is represented by a linearly viscoelastic fluid, the mat of cilia is modelled as an 'active porous medium.' The propulsive effect of the cilia is modelled by a time-dependent force acting in a shear-thinned 'traction layer' between the mucus and the PCL. The effects of sur...

partment for screening colonoscopy. He had no gastrointestinal symptoms. Barium enema revealed a curiously elongated polypoid lesion, 12 cm in length, in the transverse colon (●" Fig. 1). Colonoscopy showed an elongated polyp in the transverse colon with a 4-cm long head (●" Fig. 2a) and an 8-cm long stalk (●" Fig. 2b). As the reddish head of the lesion was clearly visualized after spraying wit...
