We studied three patients in whom otorrhea occurred without bacterial infection following ventilation tube (VT) insertion. These patients took oral steroids since the conventional therapy was not effective; however, the oral steroids produced temporal effect since sticky otorrhea occurred when the oral steroids were stopped. We collected ear discharge from each patient and consulted the pathologist about histopathologic findings of it. We identified the predominant eosinophilic infiltration at specimen. We tried to relate this type of otitis media with eosinophilic otitis media (EOM) and treated the patients with intratympanic steroid injection.

OBJECTIVE: The prolactinoma is the most common pituitary tumor and sometimes shows severe invasiveness to the adjacent cavernous sinus, especially in the male patient. The dopamine agonist can be used as an alternative treatment modality to surgery. But, the transsphenoidal or transcranial approach for tumor removal has been more preferred treatment option of neurosurgeons in invasive prolactinoma. Especially rapid decompression of mass effect and resolution of the neurologic deficit is demanded. The prospective study is done in order to identify the therapeutic efficacy of bromocriptine as an initial treatment option for the invasive prolactionomas. METHODS: Twenty patients with invasive prolactinoma were studied. Preoperative neurological and endocrinological evaluations were done, and size and invasiveness of the tumor was estimated on MRI. Bromocriptine was administrated by increasing dose planning reaching maximum dose at 1month of treatment, with close neurological and endocrinological monitoring. At 3months after treatment, MRI was taken and decision was made whether to continue bromocriptine or to have surgical intervention. RESULTS: Thirteen patients showed excellent result with only bromocriptine treatment. These patients showed not only marked reduction of tumor volume and prolactin level, but also, improving clinical symptoms and other hormonal deficits. 13patients who had visual field defect and decreased visual acuity had all improved visual symptoms. But, the remaining 4patients required surgical treatment due to insufficient reduction of tumor size inspite of normalized prolactin level within 3months. Remaining 2patients had 20~30% of tumor size reduction, but prolactin level was not normalized. One patient required radiation therapy. CONCLUSION: Bromociptine can be used as initial treatment for the invasive prolactinomas with careful monitoring of the neurological and endocrinological status. It should be carefully followed up for tumor size reduction within 3 months after initiation of treatment.

Lymphatic malformations in cases with macrocystic lesions can be treated with surgical excision or sclerotherapy using alcohol, bleomycin, doxycycline, or OK-432. We report a case of a 24-year-old woman who underwent percutaneous drainage and povidone-iodine sclerotherapy as primary treatment for cervical lymphatic malformation. The patient underwent povidone-iodine sclerotherapy for 3 consecutive days. After 8 months, ultrasonography of the lesion in the neck revealed complete resolution of the cervical lymphatic malformation without any complication. Povidone-iodine sclerotherapy can be a safe and cost-effective treatment option for cervical lymphatic malformation.

OBJECTIVE: This study evaluates the effect of the specific human papillomavirus (HPV) genotype as a prognostic factor in stage I-IIA cervical cancer patients following primary surgical treatment. METHODS: The medical records of 116 cervical cancer patients treated with primary surgical treatment were reviewed. The HPV genotypes were categorized into following groups: negative and unclassified, HPV 16, HPV 18, and other high risk (HPV 31, 33, 35, 45, 51, 52, 56, and 58). RESULTS: Among the HPV genotypes, HPV 16 predominated (40.52%), followed by intermediate risk and unclassified (25%), HPV 18, 45, and 56 (17.24%) and negative (17.24%). In univariate analysis, HPV genotypes (P=0.03), parametrial spread (P=0.02), depth of invasion (DOI) (P<0.01) and lymph-vascular space invasion (P=0.02) were significantly associated with progression free survival (PFS). In multivariate analysis, HPV 18 (hazard ratio [HR], 5.2; 95% confidence interval [CI], 1.29 to 20.90; P=0.02) and > or =one half of DOI (HR, 5.4; 95% CI, 1.08 to 27.31; P=0.04) were significantly associated with PFS. HPV genotypes are not significantly associated with overall survival. CONCLUSION: HPV 18 was a poor prognostic factor for the PFS in stage I-IIA cervical cancer patients following primary surgical treatment. Careful long-term observation and regular exams are recommended for cervical cancer patients with HPV 18 compared to those with other HPV genotypes.

Classical swine fever virus (CSFV) causes a highly contagious disease among swine that has an important economic impact worldwide. CSFV strain LOM is an attenuated virus of low virulent strain of Miyagi isolated from Japan in 1956. Eight DNA fragments representing the genome of the CSFV strain LOM were obtained by RT-PCR. These were used to determine the complete nucleotide sequence and construct a full-length cDNA clone which was called Flc-LOM. Sequence analysis of the recombinant clone (Flc-LOM) revealed the presence of eight mutations, resulting in two amino acid substitutions, when compared to the parental sequence. RNA transcripts of both LOM and Flc-LOM were directly infectious in PK-15 cells. The rescued Flc-LOM virus grew more slowly than the parental virus, LOM, in the cells. Intramuscular immunization with Flc-LOM was safe and highly immunogenic in pigs; no clinical signs or virus transmission to sentinel animals were observed after 35 days. CSFV-specific neutralizing antibodies were detected 14 days post-infection. After challenge with the virulent CSFV strain SW03, pigs immunized with Flc-LOM were shown to be fully protected. Thus, our newly established infectious clone of CSFV, Flc-LOM, could serve as a vaccine candidate.

OBJECTIVE: A general orientation along the cervical spine could be estimated by external landmarks, and it was useful, quick and less exposable to radiation, but, sometimes it gave reference confusion of target cervical level. The authors reviewed the corresponding between the neck external landmarks and cervical levels. METHODS: Totally 1,031 cervical lateral radiographs of different patients were reviewed in single university hospital. Its compositions were 534 of males and 497 females; 86 of second decades (10-19 years-old), 169 of third decades, 159 of fourth decades, 209 of fifth decades, 275 of sixth decades, and 133 of more than seventh decades (>60 years-old). Reference external landmarks (mandible, hyoid bone, thyroid cartilage, and cricothyroid membrane) with compounding factors were reviewed. RESULTS: The reference levels of cervical landmarks were C2.13 with mandible angle, C3.54 with hyoid bone, C5.12 with thyroid cartilage, and C6.01 with cricothyroid membrane. The reference levels of cervical landmarks were differently observed by sex, age, and somatometric measurement (height) accordingly mandible angle from C1 to C3, hyoid bone from disc level of C2 and C3 to C5, thyroid cartilage from disc level of C3 and C4 to C7, and cricothyroid membrane from C4 to disc level of C7 and T1. CONCLUSION: Surface landmarks only provide general reference points, but not correspond to exact levels of the cervical spine. Intraoperative fluoroscopy ensures a more precise placement to the targeted cervical level.

We introduce a new operative method for acute epidural hematoma(AEDH) through small craniotomy. Between January 1999 and December 2001, 63 patients underwent craniotomy in our hospital to evacuate an acute posttraumatic epidural hematoma. Among these, we operated 18 patients with linear scalp incision and about 4 X 4cm sized small craniotomy. After operation, neurological symptoms were improved and there were no significant postoperative complications in all patients. This operative method is simple and less time consuming. It can be done under the local anesthesia and may be useful to all AEDH without severe brain swelling, subdural hematoma and intracerebral hematoma.

BACKGROUND/OBJECTIVES: Jerusalem artichoke has inhibitory activity against α-glucosidase and decreases fasting serum glucose levels, which may be related to its fructan content. The biological activity of fructan can be influenced by the degree of polymerization. Thus, in this study, the inhibitory effects of original and fermented purple Jerusalem artichoke (PJA) on α-glucosidase were compared in vitro. Additionally, the anti-diabetes effect of Lactobacillus plantarum-fermented PJA (LJA) was studied in a non-insulin-dependent diabetes mellitus animal model (C57BIKsJ db/db). MATERIALS/METHODS: The water extract of PJA was fermented by L. plantarum, and two strains of Bacillus subtilis to compare their anti-α-glucosidase activities in vitro by α-glucosidase assays. The anti-diabetes effect of LJA was studied in a non-insulin-dependent diabetes mellitus animal model (C57BIKsJ db/db) for seven weeks. During the experiment, food intake, body weight, and fasting blood glucose were measured every week. At the end of the treatment period, several diabetic parameters and the intestinal α-glucosidase activity were measured. RESULTS: The LJA showed the highest α-glucosidase inhibitory activity in vitro. In the in vivo study, it resulted in a significantly lower blood glucose concentration than the control. Serum insulin and HDL cholesterol levels were significantly higher and the concentrations of triglycerides, non-esterified fatty acids, and total cholesterol were significant lower in mice treated with LJA after seven weeks. In addition, the intestinal α-glucosidase activity was partially inhibited. CONCLUSIONS: These results suggested that LJA regulates blood glucose and has potential use as a dietary supplement.
