Objective : To observe effects of TKM (Traditional Korean Medicine) treatment for psoriasis vulgaris. Methods : We did retrospective chart review for 32 psoriasis vulgaris patients who had been treated by TKM. TKM treatment included acupuncture, herb med, external herbal solution and moxibustion. Result : PASI (Psoriasis Area and Severity Index) 75 responding rate at treatment week 16 was 71.9%. Mild symptom patients' improvement rate and moderate to severe symptom patients' improvement rate was similar. Mean PASI score was increased until treatment week 4 to 8, and after that period, mean PASI score was decreased. Conclusion : This study suggest that TKM may be an effective treatment for psoriasis vulgaris.

Malignant oncocytoma(oxyphil cell adenoma) is a extremely rare malignant tumor of the salivary glands and almost occurs in the parotid gland. A case of malignant oncocytoma of the parotid gland occurring in a 63 year old man is reported. Establishing a diagnosis of malignant oncocytoma essentially requires the application of two sets of criteria to the tumor under examination. First, the tumor cells must be identified as oncocyte and second, malignancy must be determined. Histochemical stains are not as useful as generally believed. Electron microscopy confirms the diagnosis by demonstrating an abundance of mitochondria. The diagnosis of malignant oncocytoma depends on several additional criteria in addition to cellular and nuclear pleomorphism, including lack of encapsulation, local infiltration, perineural and intravascular growth, and regional and/or distant metastasis. Satisfactory results from surgical resection and postoperative radiotherapy in our patient serve as additional experience in the treatment of this rare malignancy.

Kimura disease is an uncommon chronic inflammatory disorder of unknown etiology. Clinically, patients present nontender subcutaneous swelling in the head and neck region. Peripheral eosinophilia, an elevated serum IgE are also present. The clinical course of Kimura disease is often progressive, and the main problem with treatment is disease recurrence. Treatment options in the recurrent cases range from observation to surgical excision, steroid therapy, and radiotherapy. We report a case of recurrent Kimura disease, initially thought to be chronic submandibular sialadenitis, along with the appropriate review.

Vascular endothelial growth factor 2 (VEGFR2) was initially identified as a receptor of VEGF on endothelial cells with a role in regulating angiogenesis during organism development and tumorigenesis. Previously, in cancer tissue, VEGFR2 has been reported to be expressed in endothelial cells. In our research, we found that VEGFR2 was expressed not only in endothelial cells but also cancer cells in head and neck squamous cell carcinomas (HNSCCs). Knockdown of VEGFR2 in Hep2 cells could arrest the cell cycle in G0/G1, leading to a decrease in proliferation. We also present evidence that MAPK/ERK signal pathways and expression of CDK1 downstream of VEGFR2 might regulate proliferation and cell cycle arrest. Furthermore, we discovered that down-regulate VEGRF2 in Hep2 cells could significantly affect the invasion ability. Taken together, our data suggest that VEGFR2 might regulate proliferation and invasion in HNSCC cancer cells in vivo.

Objective This study is designed to investigate the effect of Korean medical therapy on Allergic purpura patients.Method This is a case report on a male and a female patients who has been suffering from allergic purpura. To reduce her symptoms, we provided with internal herbal medicine 2-3 times a day, acupuncture therapy 1-2 times a day.Results After series of treatments, the symptoms of allergic purpura were remarkably improved.Conclusions This study shows us that Korean medical treatments has remedial values for purpura patients. Hence, more studies should be demanded in Korean medicine for elevation of treatment rate.

Sinonasal malignant tumors comprise less than 1% of all cancers and 3% of all malignant tumors of the head and neck, which explains a lack of large series addressing the clinical characteristics and management of these tumors. Neck node metastasis occurs in only about 7% to 15% of malignant tumors compared with other head and neck cancers. A 90-yr-old woman presented with left palpable neck mass and right nasal mass occupying nasal cavity. Fine needle aspiration biopsy of left neck mass results in metastatic squamous cell carcinoma(SCC). PET/CT shows intense FDG uptake in right nasal cavity with bone invasion. Histopathologic examination of excised lesion in the right nasal cavity revealed SCC. We report here on a primary sinonasal SCC with contralateral lymph node metastasis.

Summary: This study evaluated the relationship between voice complaint and deviant vocal fold status with special regard to presbylarynx, in patients aged more than 60 years with pharyngeal-laryngeal complaint. The material consisted of clinical histories and images obtained by laryngoscopies of 75 patients aged more than 60 years, who had sought otorhinolaryngologic treatment. Indicative glottic characteristics of the presbylarynx, such as vocal fold bowing(VFB), prominence of vocal processes (PVP), and membranous spindle shaped glottic chink(MSC) and the presence or absence of voice complaint were analyzed Also, acoustic parameters such as fundamental frequency(Fo), jitter percent and shimmer percent were analyzed. VFB showed a strong correlation with voice complaint in male. Jitter and shimmer were correlated with VFB, PVP, MSC in female.

Primary tumors of the parapharyngeal space are rare and account for only 0.5% of head and neck neoplasm. About 80% of parapharyngeal tumors are benign and 20% are malignant. Parapharyngeal space is classified into the Prestyloid space and the Poststyloid space. The Poststyloid tumors are usually benign lesions such as neurogenic tumors, paragangliomas, vascular tumors, or aneurisms. The origins of prestyloid tumors are much more diverse pathology, the pleomorphic adenoma in parotid deep lobe is most common type. Several surgical approaches have been introduced for management of parapharyngeal tumor, such as transcervical, transparotid-transcervical and the transcervical-transmandibular approaches. This paper is aimed to present a large parapharyngeal space tumor removed via transoral approach. It is possible to remove easier by using microdebrider. The pathologic diagnosis was pleomorphic adenoma.

We reviewed retrospectively 152 patients' records with salivary gland tumors confirmed histologically at Hanyang University Hospital from Jan. 1984 to Dec. 1993. The results obtained were as follows: 1) Sites of tumors were parotid gland in 102 cases(67%), submandibular gland in 29 cases(19%) and minor salivary glands in 21 cases (14%). 2) 113 cases(74%) were benign. and 39 cases(26%) were malignant. 3) The incidence of benign and malignant tumors were 81% & 19%, 69% & 31% and 48% & 52% in the parotid gland, the submandibular gland and the minor salivary glands respectively. 4) The most frequent histologic types of benign and malignant tumors were pleomorphic adenoma (64%) and mucoepidermoid carcinoma (11%) respectively. 5) The surgical procedures include superficial parotidectomy. total parotidectomy. extended total parotidectomy & neck dissection in the parotid gland. wide excision & neck dissection in the submandibular gland and wide excision, partial maxillectomy & neck dissection in the minor salivary glands. 6) The postoperative recurrence rate were 4.4% in benign tumors and 27% in malignant tumors.

CT examination has been used in the preoperative examination of patients with head and neck cancer. The accuracy of CT in detecting nodal metastases has not been well established. We studied 35 patients (41 neck specimens) with head and neck cancer who underwent neck dissection. Surgical pathologic findings were compared with preoperative CT scan to establish the diagnostic accuracy for cervical lymph node metastases. The results of physical examination, CT scans of neck and histologic examinations were compared each other. The overall diagnostic accuracy of CT was 83.3%. Comparison with clinical accuracy shows the CT scan to be superior to the clinical examination in spite of careful physical examination, particularly in detecting occult metastases.
