Whipple's disease is an uncommon disorder, generally associated with gastrointestinal symptoms; of these, diarrhea is a common feature. We report a case of Whipple's disease associated with chronic constipation which was not diagnosed until after Giardia lamblia infestation had caused diarrhea. To the best of our knowledge this association has not(More)
We ultrastructurally examined pancreatic islet containing alginate/poly-L-ornithine (AG/PLO) coherent microcapsules (CM) which we had previously developed in our laboratory. Specific issues, such as extent of CM coherency as well as morphologic integrity, and viability of the encapsulated islet subcellular organelles were addressed. We preliminarily(More)
Middle ear cholesteatomas were intraoperatively obtained from 6 male patients and studied under light (L.M.), transmission (T.E.M.) and scanning (S.E.M.) electron microscopy. Cholesteatoma proved to be formed by keratinizing squamous epithelium, or matrix, and by connective tissue, chorion or perimatrix. With regard to the matrix, a progressive(More)
Whipple's disease is a rare disease with protean clinical manifestations, often mimicking those of other pathological conditions. We describe two new cases, one admitted to hospital only after Giardia lamblia infestation had drawn attention to gut symptoms, and the other who was treated for a long time with steroids for suspected Horton's arteritis. Once(More)
2 h after the inhalation of monodispersed 99mTc-labeled autologous spherocytes and of commercial human albumin microspheres (HAM), 7 patients with chronic bronchitis underwent bronchofibroscopy. The fate of organic particles along the tracheobronchial tree was verified by scanning electron microscopy and the proteolytic activity (trypsin and PZ peptidase)(More)
Twelve chorda tympani segments, removed from as many patients (7 females, 5 males) affected by otosclerosis (3, as controls) and from either idiopathic (4), or traumatic (3) or herpetic (2) facial paralysis, were examined by a transmission electron microscope, in order to verify chordal ultrastructural changes, the gravity of neural damage in the various(More)
In the present work the Authors have studied the differentiation and the cellular multiplication of chick embryo skin incubated in vitro with normal human sera or with pathological human sera from patients affected by Kerion Celsi. In the following research the Authors have studied the skin structure by an optical and electron microscope and the thymidine(More)
