The author studied on the 197 cases of the pleomorphic adenoma which had been diagnosed with biopsy during the period of 1985 to 1996 at the Kyungpook National University Hospital. This study contains the statistical analysis of the clinico-pathological findings such as sex, age, location, chief complaint, duration, treatment method, size, recurrence, and treatment department in relation to anatomical location. The result were as follows : 1. The treatment department in oxter were ENT(16.2%), GS(22.8%), OMFS(18.8%), PS(12.2%). 2. The incidence of pleomorphic adenoma were parotid gland(57.8%), palatal salivary gland(20.3%), submandibular gland(17.2%), other minor salivary glands(4.5%). 3. The tumors were more common in females than males, with a male to female ratio of 1 : 1.85. 4. The peak age of ocurrence was in the forth decade. 5. The duration of the most cases were less than 5 years. 6. Although the size of the tumors was variable, the incidence was highest between 3cm and 4cm(25.4%). 7. The most prevalent chief complaint was swelling(94.9%). 8. Conservative treatment was performed 30.0%, and radical treatment was employed 70.0%. 9. The recurrence rate is 8.1%, and recurrence used to be relatively common with conservative treatment. 10. The rate of malignant transformation is 1%. 11. The anatomical location has no relationship with the factors of sex, duration, and malignant transformation. 12. There was statistical significance on the anatomical location to the treatment department, age, chief complaint, size, treatment method, recurrence (P<0.05).

Incontinentia pigmenti is an uncommon neurocutaneous genodermatosis characterized by three stages; vesicular lesions, verrucous lesions and hyperpigmentation. A two-week-old female infant showed grouped erythema-based vesiculopustules on the whole body since birth. One month later, vesiculopustular lesions began to disappear gradually. At this time, she developed linear verrucous plaques on the dorsum of the feet and hands and reticulated hyperpigmented patches on the lower extremities. At 2 months of age, vesicular lesions completely disappeared and the pigmented patches spread to the abdomen which became darker with time. The verrucous lesions diminished at 3 months of age. There were no neurological or ocular defects. We describe a case of incontinentia pigmenti with typical clinical and pathological features at each stage.

We rep a case of vulvar syringoma in a 32-year-old woman who had pruritus vulvae for 2 years. An examination of both the labia major revealed slightly thickened hyperpigmented or hypopigmented patches without yellow papules. A skin punch biopsy revealed characteristic histological findings of syringoma. Syringoma of the vulva is a rare disorder and is usually asymptomatic. Five cases of vulvar syringoma preriously reported in the Korean literature all had asymptomatic yellow or brown colored papules, but this case presented here was clinically considered as pruritus vulvae.

BACKGROUND: Anesthesia induction time is related to speed of injection, injected volume, and Keo. In the case of target controlled infusion, induction time can be controlled by adjusting the induction time mode. The aim of this study was to estimate the effect of induction time mode on variable parameters and vital signs during anesthesia induction with propofol using a target controlled infusion (TCI). METHODS: Sixty unpremedicated adult patients (ASA class I or II, 18 55 yrs) scheduled for elective surgery were randomly allocated to four groups according to induction mode. Group 1 was assigned a flash induction mode, and groups 2, 3 and 4 were assigned 2, 3 and 4min respectively. The end point of anesthesia induction was loss of eyelash reflex. Various parameters including induction time, infused volume, current/effect concentration at induction, and vital signs were compared. RESULTS: As the induction time mode was prolonged, induction time was delayed, but there was no difference in infused volume. Also, the current concentration decreased gradually, but the effect concentration did not show any difference. The vital signs were more stable in groups 3 and 4 compared with groups 1 and 2. CONCLUSIONS: For anesthesia induction, a rapid induction mode showed more rapid induction and low current concentration, but vital signs were relatively unstable and the effect concentration at induction showed no difference. For critically ill patients or patients with unstable hemodynamics, a more gradual induction mode for anesthesia induction in propofol TCI is recommended.

It has been known that right ACA occlusions can cause callosal disconnection syndrome. A 61-year old right-handed man was admitted because of a left ACA occlusion. MRI showed infarction of the medial frontal cortex and the anterior two-thirds of the corpus callosum. He presented with weakness and gait initiation failure in the right leg with grasp reflex, suspicious alien hand sign, and tactile anomia in the right hand. He was diagnosed with transcortical motor aphasia. He was unable to successfully complete written tasks in response to dictations and writing down spontaneous answers. He wrote down incorrect words and demonstrated paragraphism with his left hand. He could copy simple items but not written words and complex items with his left hand. Finally, he had difficulties in writing answers in response to complex verbal and written commands with his left hand, but preserved the ability to simple verbal commands, somato-sensory, and visually guided tasks. We attribute these results to the anterior callosal disconnection of the right sensorimotor cortex from the left language area.

BACKGROUND: Hypertension is the major risk factor for cardiovascular disease. The increased left ventricular mass has been recognized as an independent predictor of morbidity and mortality in hypertensive patients. The assessment of the regression of left ventricular(LV) mass after antihypertensive therapy offers prognostic information. 2D echocardiography has proved a sensitive tool for the detection of the change of LV mass. METHOD: LV mass and LV mass index were measured by area-length method of 2D echocardiography in 26 hypertensive patients and 10 normal control to evaluate the effect of betablocker(group I, n=16) and angiotensin converting enzyme(ACE) inhibitor(group II, n=10) on the regression of LV mass. RESULT: There was a significant increase of LV mass and LV mass index in the hypertensive patients(199.0+/-37.7gm, 119.2+/-21.2gm/m2) compaired to the control(129.7+/-11.7gm, 87.4+/-8.8gm/m2)(p<0.01, p<0.01). After 13.1 week treatment, LV mass was significantly decreased in group I(200.9+/-35.3gm vs 164.7+/-25.4gm)(p<0.01) and group II(195.9+/-43.3gm vs 152.4+/-27.1gm)(p<0.01). The LV mass index was also significantly decreased in group I(120.3+/-20.7gm/m2 vs 98.8+/-15.5gm/m2)(p<0.01) and group II(117.5+/-22.9gm/m2 vs 91.5+/-13.6gm/m2)(p<0.01). CONCLUSION: This results showed that LV mass can be reduced in hypertensive patients who receive beta blocker and ACE inhibitor. The effect of antihypertensive therapy on LV mass should be considered in treatment of the hypertensive patients who had hypertrophied LV.

The gene ftsH encodes a membrane-bound and ATP-dependent protease that is involved in a variety of cellular functions including heat-shock and stress response. Streptococcus pneumoniae DNA encompassing most part of the ftsH gene was cloned in Escherichia coli and sequenced. Due to the unsuccessful cloning as seen in other pneumococcal promoters, the 5'-end of the gene including the upstream promoter region was amplified by inverse polymerase chain reaction and then sequenced by cyclic sequencing. The amino acid sequence that is deduced from the 1,959 bp-long ftsH gene is very similar to FtsH of several gram-positive bacteria and E. coli within the region responsible for the AAA (ATPase associated with diverse cellular activities) function. Except for the N-terminal domain that contains a short extracellular region between two mernbrane-spanning segments, pneumococcal FtsH shows striking sequence similarity to that of a closely related species Lactococcus lactis within the conserved cytoplasmic domain where two ATP-binding motifs, the AAA Signature motif, and a zinc-binding motif are found.

BACKGROUND: Etomidate is a rapid-acting sedative/hypnotic agent with little or no cardiovascular effect and a high therapeutic index. For this reason, etomidate has been used as an anesthetic induction and maintenance agent in patients with poor cardiovascular reserve. Bispectral index (BIS), a parameter derived from electroencephalography (EEG), has been proposed as a measure of anesthetic effect and is shown to correlate with increasing sedation and loss of consciousness. To establish its utility for this purpose, it is important to determine the correlation among BIS, measured drug concentration, and increasing levels of sedation. This study was designed to evaluate this relation for etomidate. METHODS: Eighteen adult patients scheduled for elective surgery, ASA physical status I or II, were included. Etomidate was administerd until loss of consciousness (loss of verbal contact) using syringe pump with a constant rate (150 ml/h) and patients were observed until regaining consciousness as decided by prompt verbal response on command of "open your eyes". A BIS was monitored, arterial blood samples were obtained for analysis of drug concentration, and the patients were evaluated for level of sedation by the responsiveness portion of the modified observer's assessment of alertness/sedation (OAA/S) scale. RESULTS: The BIS (r = 0.86) correlated significantly with the OAA/S more than the etomidate plasma concentration (r = 0.57). The BIS values, OAA/S, and blood concentrations were 50, 1.26, and 1337 ng/ml at induction and 75, 4.6, and 236 ng/ml at awakening, respectively. CONCLUSIONS: We concluded that the BIS accurately predicted level of sedation with etomidate during anesthesia induction, but the correlation between blood concentration and level of sedation was less strong.
