Computed tomography (CT) seems to be the best imaging modality to diagnose an enterovesical fistula, but is not always able to demonstrate enterovesical fistula itself. In this case report, we present Tc-99m HMPAO white blood cell (WBC) scintigraphic findings of an enterovesical fistula complicating Crohn's disease. A 22 year-old male presented with a one-month history of urinary symptoms such as dysuria, hematuria, and frequency. The patient had intermittent right lower quadrant pain, diarrhea and hematochezia. Enterovesical fistula was highly suggestive in pelvic CT which showed air density in the urinary bladder, but cystoscopy failed to find an opening of the fistula. Tc-99m HMPAO WBC scintigraphy for evaluation of inflammatory bowel disease incidentally demonstrated enterovesical fistular tract. Crohn's disease was later confirmed by histologic examination of the surgical specimen. In our patient, Tc-99m HMPAO WBC imaging was helpful in determining the location of the fistula as well as assessing the disease activity and extent of the Crohn's disease.

BACKGROUND: Because of wide individual variations in response to sedative and the level of sedation desired by different patients, inadequate sedation is frequent during surgery. Patient-controlled sedation is a logical extension of patient-controlled analgesia to find and maintain their own steady-state of sedation by self-administration of sedatives during surgery. The purpose of this study was to evaluate the feasibility of patient-controlled sedation compared with anesthesiologist-controlled sedation during surgical spinal anesthesia. METHODS: Unpremedicated forty adult patients who received spinal anesthesia for lower extremity surgery were randomly allocated into two groups (n=20 for each group). After selection of target state of sedation according to sedation scale, patient-controlled sedation (PCS) group self-administered 0.5 mg (1 ml) intravenous midazolam in increments using a Walkmed PCA infusor and anesthesiologist- controlled sedation (ACS) group administered by the anesthesiologist as the same manner to achieve previously selected sedation state. Sedation score, vital signs, SpO2 were checked 5, 10, 20, 30, 40min after start of drug injection. RESULTS: The sedation scores patient desired were 4.4 +/- 0.8 in PCS group and 4.3 +/- 0.7 in ACS group. These scores were achieved 20min after start of injection in PCS group and 40 min in ACS grou p (p<0.05). Degree of satisfaction was higher in PCS group compared with ACS group (1.5 +/- 0.6 vs 2.1 +/- 0.8, p<0.05). No complications were detected in two groups. CONCLUSIONS: PCS using midazolam was better than ACS in terms of early achievement of sedation state patient desired and degree of satisfaction.

We report a 33-year-old man with AIDS dementia complex, which is one of the most common neurologic complica-tion of HIV-1 infection. The man presented with mild psychomotor slowing and episodic loss of consciousness about 5 years after the detection of the HIV-1 infection. His symptoms included forgetfulness, concentration difficulties, apathy, and psychomotor retardation which progressed rapidly evolving into the characteristic features of terminal HIV-1-asso-ciated dementia complex, such as severe dementia, mutism, incontinence, and paraparesis before death. Brain MRIrevealed diffuse confluent high signal intensity lesions in the subcortical white matter on the T2 weighted image. HIV encephalitis (AIDS dementia complex) was confirmed by a brain autopsy.

PURPOSE: Endoscopic thyroidectomy has recently been widely used in clinical practice. The operative method can be classified into CO2gas insufflation and the gasless technique. This study assessed the safety of low pressure CO2gas insufflation (up to 6 mmHg) by performing continuous measurement of the end-tidal CO2 (ETCO2) pressure. METHODS: From March 2003 to October 2006, 95 patients (90 hemithyroidectomies and 5 total thyroidectomies) underwent endoscopic thyroidectomy. The low pressure CO2gas insufflation technique was applied in all cases. The ETCO2 pressure of the patients was measured by capnometry at the time of a pre-gas insufflation status (0 minutes) and at the time of post-CO2gas insufflation (30 minutes) and then it was measured every 30 minutes with also performing capnograms. We analyzed the ETCO2 pressure at the time of the pre-CO2gas insufflation status (0 min) and we compared this with that of each status by using paired T-test. RESULTS: For all 95 cases, the mean patient age was 36.2+/-9.1 (range: 21~57 years), the mean tumor size was 1.7+/-1.1 (range: 0.1~4.5 cm) and the mean operative time was 135.0+/-46.1 (range: 50~340 min). The mean ETCO2 pressure (mmHg) was 33.0+/-3.9 at the time of pre-CO2gas insufflation status (0 min); the mean ETCO2 pressure was 31.1+/-3.7 at 30 min (n=95), 33.5+/-3.7 at 60 min (n=95), 35.2+/-3.6 at 90 min (n=95), 34.9+/-3.7 at 120 min (n=90), 34.6+/-3.8 at 150 min (n=70), 34.1+/-3.4 at 180 min (n=40), 34.3+/-5.2 at 210 min (n=15) and 34.0+/-4.2 at 240 min (n=9). There was a significant difference the early post-CO2gas insufflation status (P<0.05 at 30 min, 90 min, 120 min), but there was no significant difference in the late post-CO2gas insufflation status (P>0.05; at 60 min, 150 min, 180 min, 210 min, 240 min). At each time point, the ETCO2 pressures were all within the normal range. CONCLUSION: We successfully performed endoscopic thyroidectomy with using the low pressure CO2gas insufflation technique and there were no significant complications. We think that performing endoscopic thyroidectomy with using the low pressure CO2gas insufflation technique is a safe procedure.

BACKGROUD: Drug resistant virus has been seen with all effective antiretroviral drugs in current practice. The isolation of resistant virus from subjects is associated with more rapid clinical outcome. The presence of resistance-conferring mutations in a patient in whom therapy is failing indicates that other antiretroviral drugs should be considered. So, the identification of drug resistant Human Immunodeficiency Virus (HIV-1) mutations is of increasing importance. Zidovudine monotherapy for HIV-1 infection has been widely used in Korea since 1990. So, the prevalence of zidovudine resistant virus has been expected to be high. The purpose of the present study is to determine the prevalence of zidovudine resistant HIV-1 among zidovudine-naive Korean patients. METHODS: We tested drug susceptibility of HIV-1 isolated from 19 zidovudine-naive Korean patients. We amplified a portion of gene reverse transcriptase of HIV-1 by RT nested PCR method. The susceptibility of HIV-1 to zidovudine was determined by sequencing the DNA base pairs of gene reverse transciptase. RESULTS: Two (10.5%) of 19 HIV-1 isolates from zidovudine naive patients showed resistance conferring mutations to zidovudine. Two (2.1%) of 95 codons analysed from zidovudine naive patients showed mutations conferring resistance to zidovudine. CONCLUSION: The prevalence of zidovudine resistant HIV-1 was 10.5% among zidovudine-naive Korean patients.
