annular pancreas (ap) is a rare congenital abnormality in which pancreatic tissue completely surround the duodenum. presentation of ap in adulthood is very rare and obstructive jaundice is one of the uncommon manifestations of ap in adults. herein; we reported a 47 years old woman who presented with icterus, midcommon bile duct stricture and annular pancreas. she was diagnosed as pancreas cance...

A 63-year-old man presented with symptomatic severe mitral regurgitat ion. Both trans-esophageal 3-D echocardiography and operative linear measurements showed a 25 mm long A2 anterior leaflet with a very wide (23 mm) prolapsing 30 mm long P2 posterior mid-scallop (Figure 1A,B). P1 and P3 were diminutive in height and width (Figure 2). A ‘haircut’ posterior leaflet-plasty was done to maintain le...

Background: A pyogenic granuloma (PG) is a common benign vascular lesion found in the oral cavity. The gold standard treatment of this lesion, comprising surgical excision and elimination etiological factors, cannot avoid tooth loss case an aggressive granuloma. Because prominent properties 980 nm 635 diode lasers photocoagulation photobiomodulation, we applied these wavelengths large wi...

Granulomas play an essential role in the sequestration and killing of mycobacteria in the lung; however, the mechanisms of their development and maturation are still not clearly understood. IL-17A is involved in mature granuloma formation in the mycobacteria-infected lung. Therefore, IL-17A gene-knockout (KO) mice fail to develop mature granulomas in the Mycobacterium bovis bacille Calmette-Gué...

The mode-matching applications to scattering from circular and annular apertures in a thick perfectly conducting plane are reviewed. The Hankel and Weber transforms are utilized to solve the boundary-value problems of circular and annular apertures. Simple electrostatic problems are presented to illustrate the mode-matching method in terms of the Hankel and Weber transforms. Various types of We...

• Idiopathic inflammatory disease of the skin, hair, nails and mucous membranes, seen most commonly in middle-aged adults • Flat-topped violaceous papules and plaques favor the wrists, forearms, genitalia, distal lower extremities and presacral area • Clinical variants include annular, bullous, hypertrophic, linear, ulcerative and lichen planopilaris • Histologically, there is a dense, band-lik...

A tangent linear adjoint for a low-resolution dynamical model of the atmosphere is used to derive the optimal forcing perturbations for all state variables such that after a specified lead time the model response has a given projection, in terms of an energy norm, on the pattern associated with the 51-yr trend in the Northern Hemisphere winter tropospheric circulation, 1948/49–1998/99. A featur...

Cholesterol granuloma is a pathological lesion affecting the mastoid air cells due to partial obstruction of its aireation. It is commonly unilateral. It is usually associated with glue ear with intact ossicles. Histologically, it is characterized by the presence of large pointed crystals and giant cells. Its treatment is either conservative steroid therapy or surgical removal of the granuloma ...

PURPOSE To report the clinicopathologic features of a case of conjunctival synthetic fiber granuloma. CASE REPORT A 6-year-old girl presented with a slow-growing red nodule in the right inferior conjunctival sac with no history of surgery or trauma. Histopathological examination revealed foreign body type granulomatous inflammation around birefringent fibers of variable colors consistent with...
