Herpes zoster is caused by reactivation and multiplication of a latent varicella-zoster virus infection. Reactivation can frequently occur in older adults and immunosuppressed individuals. It is hypothesized that this is related to an aging society and a corresponding increase in the number of people with underlying chronic diseases, such as cancer and diabetes, that lower immunity. Clinically, the patient complains of pain, and a vesicular rash presents on one side of the face up to the midline in the dermatomes associated with the affected ganglion. Herpes zoster of the oral mucosa is rare. When oral lesions do occur, they are most often concurrent with pathognomonic unilateral linear vesicular skin lesions, facilitating both clinical diagnosis and management of the condition. Cases limited to the oral mucous membrane alone are most unusual. Treatment includes antiviral agents and analgesics for pain control. Antivirals should be administered within 72 hours of onset. Early diagnosis and treatment are important to avoid complications, such as postherpetic neuralgia. The present case report describes the adequate management of a patient diagnosed with shingles which affected the right side of the face and oral cavity. In addition, a literature review is presented.

In order to study the effect of oral administration of Mawhangyounpye-tang against to asthma, astham was induced to allergy-sensitive Balb/c mouse with ovalbumin using method of Hatfield et al (1997). The changes of diameter lumen of upper portion of the trachea, lung weight, gross appearance of lung, histological profiles of lung and trachea, numbers of cellular compartments in the bronchoalveolar lavage fluid (BALF), numbers and morphology of the mast cells in the trachea, numbers of mucus-secretory cell in the broncus, morphology of the bronchus, ultramicroscopical appearance of surface of trachea and number of cilia and mucous-secretory cells by scanning electron microscope. Obtained results were as follows. 1. The diameters of trachea lumen were significantly decreased in asthma induced control groups and these decreasing were result from hypertrophy of mucous membrane. However, these phenomena were dramatically recovered in the Mawhangyounpye-tang dosing groups. 2. Lung weights and black spots, which were result from infiltration of inflammatory cells, were significantly increased in asthma induced control groups but these phenomena were dramatically recovered in the Mawhangyounpye-tang dosing groups. 3. Hypertrophy of mucous membrane of trachea and bronchus and !bronchioles in the lung, peritracheal, peribronchus and peribronchiolar inflammatory cell infiltration, and mucoid exudate deposit in the lumen were observed in asthma induced control groups but these phenomena were dramatically recovered in the Mawhangyounpye-tang dosing groups. 4. Cellular compartments including neutrophil and eosinophil were dramatically increased in the BALF of asthma induced control groups but these phenomena were dramatically recovered in the Mawhangyounpye-tang dosing groups. 5. Mast cell degranulation and decreasing of the numbers of mast cells were detected in the trachea of asthma induced control groups. However, these phenomena were dramatically recovered in the Mawhangyounpye-tang dosing groups. 6. Shed, decreasing of cilia cell and increasing of mucous-secretory cells in the surface of the trachea of asthma induced control groups but these phenomena were dramatically recovered in the Mawhangyounpye-tang dosing groups. In conclusion, it Is considered that Mawhangyounpye-tang has somewhat favorable effect on the asthma because the asthma specific series of abnormalities in respiratory system were decreased after oral administratin of Mawhangyounpye-tang in this study. In future, it is needed that the toxicological and dosagespecific study of Mawhangyounpye-tang to use against asthma with safe.

Objectives: The objective of the study was to evaluate the results of nasolabial/extended nasolabial flaps as a modality for treatment of oral submucous fibrosis. Materials and Methods: Eleven patients of Stage III or IVa maximum interincisal opening were selected to be operated. Nasolabial/extended nasolabial flaps were done for both the sides. All of the flaps were done in a single stage and were inferiorly based. A similar flap harvest/surgical technique was utilized for all the cases. Results: The preoperative mouth opening ranged from 5 to 16 mm, with a mean of 10.09 mm. At 6 months the mouth opening ranged from 29 to 39 mm. Some of the complications encountered were poor scar, wisdom tooth traumatising the flap, decreased mouth opening due to non compliance and too much bulk. All of theses were managed satisfactorily. Conclusion: The nasolabial flap is a very reliable flap to restore the function of oral cavity. Important adjuvant measures are habit cessation, lifestyle changes, and aggressive physiotherapy.

The authors observed the ultrastructure of oral leukoplakia simplex of gingiva, buccal mucosa, tongue and alveolar ridge. For the purpose of clearly defining the lesions under investigation in this study, leukoplakias were cinsidered to be any white patches on the oral mucous membranes that could not be removed by rubbing and could not be classified clinically or microscopically as another diagnosable disease. The tissue to be examined were embedded in paraffin for light microscopic study. The tissue to be examined under the electronomicroscope were fixed in 2.5% glutaraldehyde in 0.1M cacodylate buffer and 1% osmic acid in 0.1M cacodylate buffer, dehydrated with guaded alchol, and treated with propylene oxide, and embedded in Epon.Ultrathin sections were obtained by LKB III ultrotome, stained with uranyl acetate/lead citrate, and examined with Corinth 500EM. The results were as follows : 1. Epithelium of leukoplakia consisted of stratum basale, stratum spinosum, stratum granulosum and stratum corneum. 2. There was hyperorthokerotosis or hyperparakeratosis. 3. Granular cells contained a lot number of membrane coating granule showing lamellar structure, clearing ot codensation, and a lot of keratohyaline granule varied in size. 4. An increased concentration of tonofilaments and an increased number of desmosomes were found in the stratum spinosum. 5. Basal lamina generally showed its continuity, but in some locatoins, its interreption and multiplication appeared.

Herpes Zoster is an acute viral infection characterized by the appearance of vesicles that occur on the skin and mucous membrane along the pathway of an involved sensory nerve. Although Herpes zoster is usually as benign viral infection, complications may occur especially when cranial nerves are involved. There are few reports of bony and dental complications by Herpes Zoster infection, all of which were isolated in a single quadrant. These include devitalized teeth, abnormal development of permanent teeth, internal resoption and spontaneous exfoliation of teeth with osteonecrosis of the alveolar bone. No agreement has been reached concerning the pathogenesis of osteonecrosis and tooth exfoliation associated with herpes zoster infection. We recently experienced series of maxillary osteonecrosis and spontaneous teeth exfoliation in patients with Herpes Zoster infection and present two cases with review of literature.

The gingiva consists of an epithelial layer and an underlying connective tissue layer. The oral epithelium is a keratinized, stratified, squamous epithelium. The epithelium can be divided into the following cell layer: basal layer, prickle cell layer, granular cell layer and keratinized cell layer. The desquamative disease of gingiva means exfoliative diseases of epithelial layer on the gingiva. The chronic desqumative gingivitis is usually related to the dematologic disorders that produce cutaneous and mucous membrane blisters. The cicatricial pemphigoid and lichen planus are representative diseases of the dermatologic cases. Patients may be asymptomatic or symptomatic. When symptomatic, their complaints range from a mild burning sentation to an severe pain. The clinical examination must be considered with a thorough history, and routine histologic and immunofluorescence studies. A systemic approach needs to achieve accurate diagnosis and treatment of the gingival desquamative diseases.

The aim of this study was to investigate the frequency of positive patch test reaction to dental materials in patients with oral mucosal diseases. Epicutaneous patch test was performed in 110 patients with oral mucosal diseases; 41 patients with oral lichen planus(OLP), 44 patients with burning mouth syndrome(BMS), 25 patients with other oral mucosal diseases including recurrent aphthous ulcer and mucous membrane pemphigoid. The obtained results were as follows: Oral gold restorations were most common in patents with oral mucosal diseases and porcelain fused metal crown, implant appeared in the order. 33 of 110 patients did not appear skin reactions (negative, 30%) and 77 patients (positive, 70%) had skin reactions including redness, rash, blisters. Dental materials causing positive reaction to patch test were mainly as gold-sodium-thiosulfate (26.7%), nickel sulfate(Ni) (22.7%), cobalt chloride(Co) (14.7%), palladium chloride(Pd) (11.9%), potassium dichromate (10.7%) in order, respectively. In conclusion, old metal restorations could be the cause of oral mucosal diseases and epicutaneous patch test could be used as a tool to improve the oral conditions.

Lichen planus is a common, chronic inflammatory disease of the skin and mucous membrane for which no precise causes have been confirmed. But it is often connected with infections. Helicobacter pylori(H. pylori) among various bacteria has been associated with the cause of gastritis, peptic ulcer and gastric cancer. Considering the similarities of histological features between gastric ulcer and oral ulcers, it is resonable to assume that H. pylori might also be involved in the development oral mucosal ulceration. So we employed this study to investigate the possible involvement of H. pylori in the aetiology of erosive oral lichen planus. We analyzed detection rate of H. pylori in saliva of patients with erosive oral lichen planus by nested PCR. As a result, it revealed a significant difference statistically by showing positivity in 16 to 21(76.2%) saliva samples of patients group and in 11 of 44(25%) saliva samples of control group(P>0.001). We were able to suppose that H. pylori in saliva can be related to cause of erosive oral lichen planus.

The current research concerns the clinicopathological significance of MHC class I chain-related protein A (MICA) expression in oral squamous cell carcinomas (OSCCs). The expression and location of MICA protein in 14 normal oral mucous and 45 cancerous and para-cancerous tissues were assessed by immunohistochemistry and levels of MICA mRNA expression in 29 cancerous and para-cancerous tissues were determined by the real-time polymerase chain reaction. Data were analyzed with the SPSS16.0 software package. MICA was found to be located in the cytoplasm and plasma membrane. Expression was higher in para-cancerous than in cancerous tissues (P < 0.05). However, no statistical difference was found between the following: 1) para-cancerous tissue with normal mucosa; 2) normal mucosa with cancerous tissue;and 3) among different clinicopathological parameters in OSCC (P > 0.05). The level of MICA mRNA was higher in OSCCs than in para-cancerous tissues, and was correlated with the regional lymph node status and disease stage (P < 0.05). The levels of MICA protein and mRNA expression differ among normal oral mucosa, para-cancerous tissue, and cancerous tissue. MICA may contribute to the tumorigenesis and progression of OSCC.
