BACKGROUND AND OBJECTIVES: Advanced or recurrent laryngeal cancers after chemoradiotherapy were mainly treated by total laryngectomy because of inadequate surgical margin, multifocal recurrent site, and delayed diagnosis. Recently, voice preservation through conservative laryngeal surgery in case of advanced or recurrent laryngeal cancer with strict application of surgical indication became possible. In this study, authors studied the usefulness of surpracricoid partial laryngectomy (SCPL) for advanced or recurrent laryngeal cancers is discussed. MATERIALS AND METHOD: Twenty-five laryngeal cancer cases of cricohyoido-epiglottopexy (CHEP) or cricohyoidopexy (CHP) from May 1996 through April 2001 were analysed retrospectively. In recurrent cases after radiotherapy, there were 8 cases with glottic T1, 6 with T2, 3 with T3, one with T4, one with supraglottic T2 and T3. In advanced cases without radiotherapy, there were 3 cases with glottic T3 and 2 with supraglottic T3. Evaluation of oncological and functional results were conducted. The mean follow-up period was 29.1 months. RESULTS: Local recurrence occurred in 1 patient (4.3%) and cricoid perichondritis in 5 patients (21.7%), laryngocutaneous fistula in 1 patient (4.3%) after the operation. Four patients (17.3%) had to be treated with completion laryngectomy. Voice function was preserved in 19 patients (82.7%). CONCLUSION: Our experience with supracricoid partial laryngectomy with CHEP or CHP suggests that this technique can be a valuable alternative to the total laryngectomy in the recurrent or advanced laryngeal cancer.

Reversible posterior leukoencephalopathy with hypertension is characterized by an acute and severe rise in blood pressure with headache, altered mental status, cortical visual disturbance, seizure and transient edematous changes in neuroimaging. The most common abnormality in neuroimaging is presumed edema involving the cortical and subcortical white matter predominant in the posterior region of the cerebral hemisphere and rarely the cerebellum and the brain stem, but not in the spinal cord. We experienced a case of 10-year-old girl with hypertensive encephalopathy involving the brainstem and the spinal cord.

BACKGROUND AND OBJECTIVES: Many authors(Simmons,1973, McGath et al.,1989) described that a small percentage(1-2 %) of patients initially complaining of vertigo was found to have bilateral vestibular failure (BLVF). This study evaluates the findings of vestibular function test (VFT) including rotating chair test (ROT) and computerized dynamic posturography test (CDP) in the patients with BLVF demonstrated by caloric test and others. Method : 400 vertigo patients were given VFT from June,1994 to October,1995. In the patients who had absent or reduced responses (total eye speed <10 degrees per second) in cold (17 C) water caloric testing or decreased responses in the range of lower fequencies during ROT, we evaluated their VFT results and clinical features. RESULTS: There were 38 cases out of total 400 patients(9.5%). Many patients with BLVF had rotational response magnitudes (at 0.04 Hz and above) that were within normal limits. CBP has shown vestibular dysfunction patterns in 32 patients. Hearing tests were normal in 9 cases and mixed hearing loss in 2 cases. Many patients experienced several episodes of acute vertigo with persistent imbalance; Only 4 patients complained of persistent oscillopsia. Viral infection (vestibuloneuronitis), immune reactions and toxic factors may play a role in the etiology of this rare BLVF. CONCLUSION: Our incidence of 9.5% is much higher than what was reported in the literature. Herb medications and frequent injections of aminoglycosides may be responsible for this higher incidence of BLVF. ROT is useful in detecting and predicting the remaining vestibular function in the BLVF patients.

Leukocytosis and neutrophilia is common during the acute phase of Kawasaki disease whereas leukopenia is not common and severe neutropenia is rare. Severe neutropenia is defined as absolute neutrophil count less than 500/mm3. There are only few publicatons reporting of atypical Kawasaki disease with severe neutropenia. We report a case of atypical Kawasaki disease with severe neutropenia.

Choledochocele is a rare cystic dilatation of the distal common bile duct in the wall of the duodenum. It is a type III choledochal cyst among the five types according to Todani's modification of the Alonso-Lej classification, and this type lll cyst comprises less than 4% of all choledochal cysts. We experienced one case of choledochocele in a 41-year-old woman who presented with recurrent pancreatitis, and we report on this case, along with a review of the literature.

OBJECTIVE: To assess the clinical usefulness of ultrasonography for the diagnosis of mild and very mild carpal tunnel syndrome. METHOD: Ultrasonographic evaluation was performed in 39 hands of 29 patients with mild and very mild carpal tunnel syndrome according to Bland's neurophysiologic grading scale. Controls included 41 hands of 34 subjects without electrophysiologic evidence of carpal tunnel syndrome. Ultrasonographic findings were evaluated quantitatively with regard to the cross-sectional area, the flattening ratio, the swelling ratio of the median nerve, and palmar displacement of the flexor retinaculum. The analysis of differences between controls and patients group were done by independent t-test. Cut-off values using receiver operation characteristic, were calculated. RESULTS: Patients had significantly increased cross sectional area and flattening ratio of the median nerve at proximal carpal area, palmar displacement of the flexor retinaculum at proximal carpal area. A critical value of equal or higher to 8.5 mm(2) for cross-sectional area at the pisiform level showed a sensitivity 79.5%, a specificity of 95.1%, which had most diagnostic value compared with the value of cross-sectional area at the distal radius level, flattening ratio at the pisiform level and palmar displacement. CONCLUSION: Ultrasonography was useful in the diagnosis of mild and very mild carpal tunnel syndrome.

Fungal balls consist of rounded conglomerates of fungal mycelia, which can form within a preexisting cavity. They are mostly found in the paranasal sinuses in the head and neck regions. Cholesterol granuloma is a fibrotic lesion that develops as a tissue response to a foreign body such as cholesterol crystals or hemosiderin and is often associated with chronic otitis media. We present the unusual case of a 62-year-old male who was treated for chronic otitis media, which was histologically confirmed as a fungal ball and cholesterol granuloma in the middle ear cavity following tympanomastoidectomy. This is the first reported case of synchronous fungal ball and cholesterol granuloma in the middle ear cavity.

OBJECTIVES: Neurotensin (NT), of which functions are evoked by its interaction with neurotensin receptors (NTR), coexists with mesolimbic dopamine and regulates endogenous dopamine release. Recent studies have shown that NT with NTR exerts neuroleptic-like activity within the central nervous system and may play an important role in the pathogenesis and in the treatment of schizophrenia. We have examined the genetic association between schizophrenia and tetranucleotide repeat polymorphism in the 3'-flanking region of the NTR gene to investigate the possible contribution of the NTR gene to the schizophrenia susceptibility. METHODS: Among 23 alleles identified, the subjects were 120 patients (male 91, female 29) with schizophrenia and 106 normal healthy controls (male 84, female 22). They were unrelated native Korean. PANSS was used to determine positive or negative subgroup in the schizophrenic patients.Using polymerase chain reaction and polyacrylamide gel electrophoresis, tetranucleotide repeat polymorphism (CCTT and CTTT) in the 3'-flanking region of NTR gene was observed. For a comparison of NTR gene's allelic frequencies between patients with schizophrenia and normal healthy controls, chi-square test and Bonferroni's correction was performed. RESULTS: The frequency of A10 allele (base pair size=399) was significantly higher in normal healthy controls than schizophrenia (x2=16.4902, df=1, p<.000). In the comparison between schizophrenic patients with negative symptoms and normal controls, the frequency of A10 allele was significantly higher in normal healthy control subjects than patients with schizophrenia (x2=21.33, df=1, p<0.001). In the case of male, the frequency of A10 allele of schizophrenia was significantly higher than normal controls (x2=13.71, df=1, p<0.001). CONCLUSIONS: NTR gene was negatively associated with schizophrenia. NTR gene's tetranucleotide repeat polymorphism may provide some protective function against schizophrenia.

The Pogo mouse is an autosomal recessive ataxic mutant that arose spontaneously in the inbred KJR/MsKist strain derived originally from Korean wild mice. The ataxic phenotype is characterized by difficulty in maintaining posture and side to side stability, faulty coordination between limbs and trunk, and the consequent inability to walk straight. In the present study, the cerebellar concentrations of glutamate and GABA were analyzed, since glutamate is a most prevalent excitatory neurotransmitter whereas gammar-aminobutyric acid (GABA) is one of the most abundant inhibitory neurotransmitters, which may be the main neurotransmitters related with the ataxia and epilepsy. The concentration of glutamate of cerebellum decreased significantly in ataxic mutant Pogo mouse compared to those of control mouse. However, GABA concentration was not decrease. These results suggested that the decrease in glutamate concentration may contribute to ataxia in mutant Pogo mouse.
