Twelve severely emaciated patients with emphysema and 4 control patients with mild emaciation were studied. Arterial blood gas analysis, pulmonary function tests, and muscle biopsy were performed. According to the percentage of ideal body weight (%IBW), patients were divided into two groups of 6 patients each; one with %IBW values greater than 70.0 (group 1) and the other with %IBW values less than 70.0 (group 2), and 4 control patients with emphysema whose %IBW values were greater than 85.5. %FEV1.0, PaO2 and Hugh-Jones scores in group 2 patients were consistent with significantly greater deterioration as compared with those in group 1 patients and controls. In the muscle fibers of 11 patients and 4 controls, nicotinamide and adenosine dinucleotide tetrazolium reductase activity was studded with spots. Nemalin rods were detected in 3 specimens in group 2 and in 1 specimen each in both group 1 and controls. These changes probably result from chronic hypoxemia. Fiber type grouping accompanied by type II dominant fiber atrophy was demonstrated in 5 patients of group 2, whereas type II fiber atrophy was shown in 2 specimens from patients of group 1. Diameters of both types I and II fibers in group 2 were smaller than those in group 1 and controls. Significant correlations were observed between fiber diameters and %IBW, %FEV1.0 and %IBW, and PaO2 and %IBW. Neurogenic and disuse muscular atrophy due to both hypoxic axonal disorder and disuse is likely to be the cause of the emaciation, and a 'vicious circle' between muscular atrophy, respiratory function and hypoxemia probably exists in group 2. Since mild or moderate emaciation was observed in controls and group 1 in spite of the lack of fiber atrophy, involvement of fat and connective tissue should also be taken into consideration to determine the cause of emaciation.

In Europe, cystic echinococcosis is rare in horses and is mostly diagnosed at slaughter or postmortem examination. Equine cystic echinococcosis can be caused by various Echinococcus taxa, but only Echinococcus equinus (the "horse strain") is known to produce fertile cysts. In Europe, E. equinus appears to be endemic in Great Britain, Ireland, Spain, and Italy and has sporadically been reported in Belgium and Switzerland. The present report describes the first case of a molecularly confirmed E. equinus infection in a horse foaled and raised in Germany. The 19-year-old mare was presented for examination of inappetence, emaciation, and respiratory symptoms. X-ray radiographs of the thorax showed 2 well-circumscribed tumor-like masses, each approximately 10 cm in diameter in the caudal lung field. The horse was euthanized as its condition rapidly deteriorated. Necropsy revealed 2 thick-walled hydatid cysts, each 7-8 cm in diameter in the lung. The tri-layered cyst walls consisted of an outer adventitial layer, a laminated acellular intermediate layer, and an inner germinal membrane. Grossly, the cysts contained a clear, amber liquid with hydatid sand. Light microscopy of the hydatid sand revealed free protoscoleces, intact and ruptured brood capsules, calcareous corpuscles, and debris. Samples of protoscoleces underwent molecular characterization, and the diagnosis of E. equinus was confirmed by restriction fragment length polymorphism-polymerase chain reaction and sequence analysis of the complete mitochondrial nicotinamide adenine dinucleotide dehydrogenase subunit 1 gene.
