PURPOSE: The overuse and misuse of antimicrobial agents and their resultant emergence of resistant microorganisms have made choices regarding antimicrobial therapy more difficult. We studied the changes of antibiotic sensitivity to the causative organisms of urinary tract infection(UTI) for recent 5 years in order to give some useful informations about the choice of adequate drug in the treatment of UTI. MATERIALS AND METHODS: We analysed 1191 uropathogens and their antibiotic sensitivities of the 1132 patients who admitted or visited the National Police Hospital and had more than 105cfu/ml on urine culture from January 1994 to December 1998 retrospectively. RESULTS: The common pathogenic organisms were E. coli(51.5%), staphylococcus(15.7%), pseudomonas(9.1%), klebsiella(7.5%) and enterobacter(4.0%), enterococcus(3.4%), proteus(3.1%) in order. The incidence of E. coli decreased from 50.8% in 1994 to 41.3% in 1998 but the incidence of other gram negative organisms like pseudomonas, klebsiella, enterobacter, proteus and acinetobacter increased from 24.8% in 1994 to 42.6% in 1998. In E. coli isolates(the majority of positive cultures), resistance to six antibiotics changed significantly: ampicillin(19.4% to 15.5%), piperacillin(44.1% to 32.0%), cephalothin(70.6% to 58.6%), gentamicin(62.8% to 60.2%), tobramycin(95.0% to 88.1%), and ciprofloxacin(87.6% to 76.3%). The sensitivity rates of the gram negative organisms including E. coli were very low in 1998 (ampicillin 11.6%, piperacillin 36.6%, and trimethoprim/sulfamethoxazole 49.3%). CONCLUSIONS: We think that E. coli is still the most important organism in the UTI but we shoud be concerned about the increasing incidence of other gram negative organisms like pseudomonas, klebsiella, enterobacter, proteus and acinetobacter. And prior to receiving the bacteriological report, using ampicillin, trimethoprim/sulfamethoxazole as the first choice in the treatment of UTI shoud be reconsidered.

We report a case of male infertility secondary to pituitary apoplexy, which occurred as a sequela of korean hemorrhagic fever. A 32 years old male patient with past history of korean hemorrhagic fever was studied because of infertility and erectile impotence. The size of his testicles were about 8ml in Rt. and Lt. Semen analysis, endocrinologic studies, and brain MRI demonstrated hypogonadotrophic hypogonadism due to panhypopituitarism. The patient was treated with HCG (2,000 IU) administered intramuscularly three times per week for 6 months. After the treatment, improvement of male secondary sex characteristics such as hair growth and testicle size was noted. Promotion of sexual potency and improvement of semen quality were also noted. Following the treatment, his wife conceived after 6 months.

Objectives: This study evaluated the effect of adjacent gingival blood flow on detection of pulpal blood flow (PBF) using ultrasound Doppler flowmetry (UDF) through animal study. Materials and Methods: The study included 36 right and left maxillary the third incisors and canines in 9 experimental dogs. The study included 2 main steps: In the first step, the pulse sound level (PSL) was recorded on the cervical part of each tooth without flap elevation (Group 1), with flap elevation (Group 2), and after it was repositioned in place (Group 3). In the second step, the PSL was recorded on the cervical part of each tooth (Group 4), after pulpotomy (Group 5), after partial pulp extirpation (Group 6), after complete extirpation (Group 7), and after canal filling (Group 8). In Groups 5–8, the study was performed with and without flap elevation in the left and right teeth, respectively. The PSL was graded as follows: 0, inaudible; 1, heard faintly; and 2, heard well. The difference between each group was analyzed using Friedman’s test with Wilcoxon signed-rank tests (α = 0.05). Results: In step 1, the PSL results were Group 1 > 2 and 3. In step 2, there was no significant difference between the groups when the flap was not elevated, while PSL results were Group 4 > 5 ≥ 6 and 7 ≥ 8 when the flap was elevated. Conclusions PBF is affected by gingival blood flow when measured with UDF. UDF measurements require isolation of gingiva from the tooth.

BACKGROUND: Korea is an endemic area of viral hepatitis B. In spite of the HBV vaccination program since 1983, the prevalence of HBV antigen had remained high, which was 3.9% in male, 2.7% in female in 1994. But there is no approved management guideline on isolated anti-HBc and the meaning of which is not clear except the evidence of past infection. Therefore, we tried to investigate the factors which influence the seroconversion of anti-HBs during follow-up period. METHODS: Medical records of 239 subject with isolated anti-HBc, who visited a health promotion center from 1995 to 1997 and who were retested at least once during the 1-3 years' follow-up period, were analyzed. RESULTS: The seroconversion rate of anti-HBs was 45.61%(109/239) on the follow-up test. The number of newly vaccinated or non-newly vaccinated subjects during the follow-up period was 156 and 72, respectively. The seroconversion rate of anti-HBs of each group were 57.69%(90/156) and 22.22% (16/72) respectively(p<0.01). The subjects without previous history of HBV vaccination was 103. Among them the seroconversion rate of anti-HBs of the newly vaccinated or the non newly vaccinated group were 59.70%(40/67) and 22.22% (8/36), respectively(p<0.01). Sex, age, BMI, smoking, previous history of HBV vaccination did not influence significantly on the seroconversion rate of anti-HBs among the subjects with isolated anti-HBc. CONCLUSIONS: The seroconversion rate in people with isolated anti-HBc was significantly higher in the newly vaccinated than the non-newly vaccinated regardless of the previous history of HBV vaccination in this study. In spite of the non-differentiation of an-amnestic response from primary antibody response, we can expect to benefit from HBV vaccination in those with isolated anti-HBc.59.70%(40/67) and 22.22% (8/36), respectively(p<0.01).

PURPOSE: To evaluate the clinical usefulness of 2-D Cine PC (phase contrast) technique in visualizing the pattern and the site of abnormal CSF flow and to assess the effect of a third ventriculostomy in patients with hydrocephalus. MATERIALS AND METHODS: The study group consisted of three normal controls and 13 patients with hydrocephalus, as shown on CT or MRI, and two patients who had undergone their third ventriculostomy. The technique was EKG-gated 2-D Cine PC MRI with velocity encoding 5cm/sec, TR 80msec, TE 12.3-15msec, and flip angle 15-60 degrees. Image quality was analyzed for variable sequences, and CSF flow was observed along the CSF flow pathway. We analyzed continuity and intensity of the CSF flow signal, and obstruction site and flow velocity degree were then defined. RESULTS: Systolic high and diastolic low signal intensity along the CSF flow-pathway, with normal asynchronicity and continuation, were clearly seen in normal controls. In three patients, there was obstruction at the ventricular level while others were either normal or showed a normal pattern with a weak signal. 'Normal' was defined as noncommunicating hydrocephalus and the latter as communicating hydrocephalus. In the two patients who had undergone ventriculostomy, a signal was in one case detected at the site of the third operation. CONCLUSION: A 2-D Cine PC CSF flow study enables us to see CSF flow signals noninvasively and to detect the site of obstruction of a CSF flow-pathway. It can therefore be useful for determining the application of a ventriculoperitoneal shunt and assessing the effect of a third ventriculostomy.

Plasma cell cheilitis is a rare, idiopathic, benign inflammatory disease of lips, characterized by dense plasma cell infiltrates in the upper dermis. It presents as erythematous patches with erosion usually on the lower lip of elderly people. Although, various therapeutic options, including topical steroids, intralesional injection of glucocorticoids, oral nystatin and topical antibiotics have been tried, none of them is promising. A 68-year-old woman presented with a 4-month history of erosive patches with crusts on her lower lip, which was resistant to topical corticosteroids. A histopathologic examination revealed dense inflammatory cell infiltration mainly consisting of plasma cells in the dermis, consistent with plasma cell cheilitis. She was treated with topical pimecrolimus and after 2 weeks of application, the lesion started to get better. After 7 weeks it had almost disappeared. Herein, we present a case of plasma cell cheilitis treated with topical application of pimecrolimus.

PURPOSE: To assess the usefulness of three-dimensional spiral CT angiography in the diagnosis and as a guide for the treatment of arteriosclerosis obliterans of the lower extremity. MATERIALS AND METHODS: During a recent one-year period, CTA and conventional angiography were performed in 12 patients with suspected ASO. From the upper margin of the third lumbar vertebral body to below the knee joint, helical CT scanning was performed 30-45 seconds after the injection of Ultravist 370(150-180ml) by a power injector at the rate of 2.5-3.0ml/sec via the antecubital vein. The resulting data were reformatted by SSD after reconstruction of 5mm intervals, and CTA was compared with CA for site and degree of stenotic or occlusive lesion. RESULTS: On CTA and CA, twenty-three occlusive lesions above the tibioperoneal artery were detected in 12 patients. On CA, three mild seven moderate and eight severe stenoses were seen, as well as five occlusions. There were three cases of overgrading and three of undergrading. Overall diagnostic accuracy was 73.9%(17/23). Calcifications were detected at on axial CT scanning in the two of three underestimated lesions. Migration of the thrombi was noted in one case. CONCLUSION: CTA may be useful in the evaluation of the arteries of the lower extremities, and valuable in the planning and follow-up of treatment.

The aim of this study is to review the protective effect of a bicycle helmet on each facial location systematically. PubMed was searched for articles published before December 12, 2014. The data were summarized, and the odds ratio (OR) between the locations of facial injury was calculated. A statistical analysis was performed with Review Manager (The Nordic Cochrane Centre). Bicycle helmets protect the upper and middle face from serious facial injury but do not protect the lower face. Non-wearers had significantly increased risks of upper facial injury (OR, 2.07; P<0.001) and of middle facial injury (OR, 1.97; P<0.001) as compared to helmet users. In the case of lower facial injury, however, only a slightly increased risk (OR, 1.42; 95% confidence interval (CI), 0.67-3.00, P=0.36) was observed. The abovementioned results can be attributed to the fact that a helmet covers the head and forehead but cannot cover the lower face. However, helmets having a chin cap might decrease the risk of lower facial injury.
