1/459. Identification of connexins in human oral mucosa and therapeutic effect of irsogladine maleate on aphthous stomatitis.We identified connexins 26 and 32 in human oral mucosa. The presence of the connexins indicates the presence of gap junctions in this tissue. However, immunofluorescence study found no significant differences in the expression of the connexins between patients with aphthons stomatitis and controls. Irsogladine maleate, which reinforces gap junctional intercellular communication in vitro, was effective for the treatment of transient and relapsing aphthous stomatitis, as well as symptomatic and drug-induced aphthous stomatitis. It was also useful for prevention of episodes of relapsing aphthous stomatitis, with daily administration preverting recurrence of stomatitis for more than 4 years one patient. These findings suggest that irsogladine maleate accelerates the wound healing process in oral mucosa by reinforcing gap junctional intercellular communication among oral mucosal cells; and that it is useful for the treatment and prevention of aphthous stomatitis.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
2/459. Recurrent macular corneal dystrophy type II 49 years after penetrating keratoplasty.recurrence of macular corneal dystrophy after keratoplasty is rare. We report light microscopic, immunohistochemical, electron microscopic, and serologic findings in a 78-year-old woman who underwent regrafting 49 years following the first penetrating keratoplasty. Examination of the corneal button revealed deposits of glycosaminoglycans in the graft beneath the Bowman layer, throughout the stroma, and in the endothelium with positive staining for antigenic keratan sulfate. By transmission electron microscopy, intracellular and extracellular deposits of a fibrillogranular material were detected in the stroma, descemet membrane, and endothelium. The serum level of antigenic keratan sulfate was normal. Our findings indicate that macular corneal dystrophy type II may show late recurrence after penetrating keratoplasty with intense deposition of antigenic keratan sulfate in all corneal layers.- - - - - - - - - - ranking = 0.1067513593253keywords = membrane (Clic here for more details about this article) |
3/459. Chronic herpes simplex virus type I glossitis in an immunocompromised man.herpes simplex virus (HSV) type 1 (HSV-1) infection of the tongue commonly accompanies acute primary herpetic gingivostomatitis. However, recurrent infection of the tongue is exceptional and is restricted to immunocompromised individuals. A 57-year-old man with corticosteroid-dependent chronic obstructive pulmonary disease and sciatica presented with a chronic median glossitis due to HSV-1. The main clinical and histological feature was massive necrosis of the entire mucosa. immunohistochemistry demonstrated a considerable amount of HSV gB, gC and gD envelope glycoproteins dispersed in the chorion. In contrast, HSV-1 dna was detected only in a limited number of epithelial cells using in situ hybridization. The extent of necrosis and the pattern of viral dna and envelope protein distribution represent unique features of median herpetic glossitis, which are not found in more common types of HSV infection.- - - - - - - - - - ranking = 0.14285714285714keywords = mucosa (Clic here for more details about this article) |
4/459. Successful treatment of adolescent pemphigus vulgaris by immunoadsorption method.A 15-year-old girl with pemphigus vulgaris did not respond to oral administration of prednisolone at 45 mg/day. The skin and oral mucous membrane lesions recurred after effective treatments with methylprednisolone pulse therapy and combination therapy with prednisolone and cyclosporine. The finally successful treatment involved eleven cycles of immunoadsorption using a tryptophan column and administration of a moderate dose of prednisolone. serum gamma-globulin level and anti-intercellular antibody titer decreased from 1.08 g/dl to 0.5 g/dl and 1:320 to 1:20, respectively. She has been well controlled with 21.5 mg/day prednisolone for 8 months after the final adsorption. Considering the physical, mental and social situation of adolescent student patients, immunoadsorption is a highly preferable choice among a variety of treatment modalities for pemphigus vulgaris because it makes the term of hospitalization shorter and avoids undesirable side effects from initial high dose corticosteroids.- - - - - - - - - - ranking = 0.44847888997181keywords = mucous membrane, membrane (Clic here for more details about this article) |
5/459. balanitis xerotica obliterans complicating hypospadias repair.We review the literature and report a series of eight cases of balanitis xerotica obliterans (BXO) developing in patients following primary hypospadias repair. The ages of these patients ranged from 8 to 25 years with BXO developing from 1 to 16 years postoperatively. Six patients were treated by excision of the BXO tissue and two-stage urethroplasties with full-thickness grafts. Three of these patients had further recurrence of BXO and had re-do urethroplasty using a combination of bladder and buccal mucosa. The last two patients in this series had re-do urethroplasty using bladder mucosa only and bladder-buccal mucosa technique, respectively, as first choice for BXO complicating their hypospadias repair.- - - - - - - - - - ranking = 0.42857142857143keywords = mucosa (Clic here for more details about this article) |
6/459. Histopathological findings in proliferative membrane from a patient with sarcoid uveitis.BACKGROUND: Sarcoid uveitis is occasionally accompanied by proliferative changes, such as retinal neovascularization and vitreous hemorrhage. Steroid administration, retinal photocoagulation, and vitrectomy may be indicated in such proliferative cases. CASE: A 19-year-old woman presented with proliferative sarcoid uveitis accompanied by recurrent vitreous hemorrhage. OBSERVATIONS: At the initial examination, bilateral vitreous opacity, retinal exudates, mild vitreous hemorrhage, retinal vasculitis, and neovascularization of the retina and optic disc were observed. Although prednisolone was administered and panretinal photocoagulation was performed several times, recurrent vitreous hemorrhage continued. Since the vitreous hemorrhage was not absorbed, pars plana vitrectomy and lensectomy were performed. After surgery, neovascularization and intraocular inflammation decreased, and the corrected visual acuity in the right eye improved to 20/50. Histopathologic analysis of the proliferative membrane removed during surgery revealed substantial neovascularization and numerous neutrophils in the vessels. CONCLUSIONS: Based on these findings, an inflammatory reaction as well as retinal ischemia were thought to be involved in the proliferative changes in this patient.- - - - - - - - - - ranking = 0.53375679662651keywords = membrane (Clic here for more details about this article) |
7/459. Recurrent buccal space abscesses: a complication of Crohn's disease.Oral features of Crohn's disease include ulcerations, lip fissuring, cobblestone plaques, and mucosal tags. We report the case of a 16-year old male patient with a 3-month history of abdominal pain, diarrhea, and oral ulceration. Clinical examinations revealed established intestinal lesions, a marked cobblestone appearance in the oral cavity, and an unusual pattern of presentation not previously reported in the literature: persistent, recurrent buccal space abscesses.- - - - - - - - - - ranking = 0.14285714285714keywords = mucosa (Clic here for more details about this article) |
8/459. Benefits of endorectal ultrasound for management of smooth-muscle tumor of the rectum: report of three cases.Smooth-muscle tumor of the rectum is rare, and the therapeutic strategy is still controversial. Endorectal ultrasound was used to evaluate three patients with smooth-muscle tumor of the rectum. Endorectal ultrasound demonstrated a homogenous hypoechoic tumor without invasion to the perirectal tissue in two patients. The tumor was 5 cm in diameter in one patient and 4 cm in diameter in the other patient, and they were excised locally. Their histologic types were leiomyoma and leiomyosarcoma. The third patient had a recurrent leiomyosarcoma. Proctosigmoidoscopy found a linear lesion with ulcerated mucosa on the rectal wall. Endorectal ultrasound observed a hypoechoic solid tumor of 3.5 cm x 1 cm, which involved the mucosal, submucosal, and muscle layers of the rectal wall. Disruption of the first hypoechoic layer was identified. Abdominoperineal resection was performed. Endorectal ultrasound follow-up revealed no evidence of recurrence in any of these patients. Endorectal ultrasound can help to define the extent of disease and may be a useful adjunct in deciding about the appropriate surgical procedure in these diseases.- - - - - - - - - - ranking = 0.42857142857143keywords = mucosa (Clic here for more details about this article) |
9/459. Recurrent Goodpasture's disease due to a monoclonal IgA-kappa circulating antibody.We describe the case of a 54-year-old man who first presented with a clinical syndrome manifested by recurrent pulmonary hemorrhage, hematuria, and mild renal insufficiency. Direct immunofluorescence of renal biopsy sections showed linear deposition of IgA-kappa in the glomerular (GBM) and tubular basement membranes. serum protein immunoelectrophoresis was positive for a monoclonal immunoglobulin A (IgA)-kappa protein. serum analysis showed circulating IgA anti-GBM antibodies. Treatment with high-dose steroids, cyclophosphamide, and plasma exchange resulted in resolution of the clinical picture. To the best of our knowledge, this is the first report of Goodpasture's disease associated with the presence of a circulating monoclonal IgA-kappa antibody.- - - - - - - - - - ranking = 0.1067513593253keywords = membrane (Clic here for more details about this article) |
