The prevalence of right-sided infective endocarditis is increasing with a growing number of intravenous drug abusers. A case of right-sided endocarditis is reported in a 18-year-old female heroin addict. Tricuspid valve vegetation, septic pulmonary emboli and staphyloccus aureus in blood cultures are noted. During antimicrobial therapy, she developed remittent fever and skin rash due to vancomycin. After a change of the antibiotic to teicoplanin, she was freed from fever and discharged in an improved condition.

BACKGROUND: The syphilis diagnostic algorithms applied in different countries vary significantly depending on the local syphilis epidemiology and other considerations, including the expected workload, the need for automation in the laboratory and budget factors. This study was performed to investigate the efficacy of traditional and reverse syphilis diagnostic algorithms during general health checkups. METHODS: In total, 1,000 blood specimens were obtained from 908 men and 92 women during their regular health checkups. Traditional screening and reverse screening were applied to the same specimens using automatic rapid plasma regain (RPR) and Treponema pallidum latex agglutination (TPLA) tests, respectively. Specimens that were reverse algorithm (TPLA) reactive, were subjected to a second treponemal test performed by using the chemiluminescent microparticle immunoassay (CMIA). RESULTS: Of the 1,000 specimens tested, 68 (6.8%) were reactive by reverse screening (TPLA) compared with 11 (1.1%) by traditional screening (RPR). The traditional algorithm failed to detect 48 specimens [TPLA(+)/RPR(−)/CMIA(+)]. The median TPLA cutoff index (COI) was higher in CMIA-reactive cases than in CMIA-nonreactive cases (90.5 vs 12.5 U). CONCLUSIONS: The reverse screening algorithm could detect the subjects with possible latent syphilis who were not detected by the traditional algorithm. Those individuals could be provided with opportunities for evaluating syphilis during their health checkups. The COI values of the initial TPLA test may be helpful in excluding false-positive TPLA test results in the reverse algorithm.

PURPOSE: To verify the expression of the egg activator oscillin in mouse testis and adult organs. MATERIALS AND METHODS: Genomic PCR using primers for oscillin was conducted to confirm that the PCR product was derived from cDNA. Total RNA isolated from developing, immature, and mature testis was subjected to RT-PCR and restriction analysis. In situ hybridization of adult testis was performed to localize the oscillin transcript using cRNA probe. RESULTS: Genomic PCR using the primer for RT-PCR revealed no amplification product, suggesting that the oscillin gene consists of at least two exons. The RT-PCR product of oscillin mRAN was detected in testis beginning 2 weeks after birth. Oscillin mRAN was detected in both germ and somatic cells such as Sertoli and Leydig cells by in situ hybridization. The testis showed al high level of oscillin mRAN compared with other adult organs. CONCLUSION: Oscillin is not a testis-specific transcript and therefore may have another function intracellularly as well ad serving as a trigger for egg activation.

BACKGROUND/AIMS: Needle-knife precut fistulotomy (NK-F) is a well-known freehand technique for difficult biliary cannulation (DBC). Another approach involves the use of Iso-Tome®, a modified precutting device with an insulated needle tip to prevent direct thermal injury. This comparative study aimed to evaluate the efficacy of the Iso-Tome® precut (IT-P) compared to that of NK-F for DBC. METHODS: Patients with a naive papilla who underwent early IT-P or NK-F for DBC were enrolled. DBC was defined as failure to achieve selective biliary access by wire-guided cannulation despite 5 minutes of attempted cannulation, ≥5 papillary contacts, or a hook-nose-shaped papilla. The primary endpoint was the primary technical success rate, which was based on a noninferiority model. RESULTS: A total of 239 DBC cases were enrolled. The primary technical success rates were 74.7% (89/119) in the IT-P group and 91.6% (110/120) in the NK-F group (lower limit of 90% confidence interval, −0.23; p=0.927 for a noninferiority margin of 10%). The total technical success rates were 87.4% and 95.0%, respectively (p=0.038). The mean precutting times for successful biliary access were 11.2 minutes for IT-P and 7.3 minutes for NK-F (p < 0.01). The procedure-related adverse event rates were 9.2% for IT-P and 5.8% for NK-F (p=0.318). The rates of post-endoscopic retrograde cholangiopancreatography pancreatitis were 4.2% and 2.5%, respectively (p=0.499). CONCLUSIONS: IT-P failed to exhibit noninferiority compared with NK-F regarding the primary technical success rate of DBC, but there was no difference in the frequency of adverse events.

OBJECTIVE: There is need for more objective diagnostic parameters to identify cervical dysplastic or neoplastic cells. So, we examined the p16(INK4A) expression in the cervical tissues to evaluate the value of p16(INK4A) as a diagnostic parameter. METHODS: We examined the p16(INK4A) expression by immunohistochemical staining in normal cervical tissues (n=3), preneoplastic lesions (n=6), carcinoma in situ (CIS, n=5), and invasive carcinomas (n=5) of the cervix, which were selected randomly by H and E staining from the archives of formalin-fixed and paraffin-embedded tissues and we also examined the status of human papillomavirus (HPV) infection in the same tissues. RESULTS: The positive rates of p16(INK4A) expression was significantly higher in all abnormal cervical tissues including subclinical papillomavirus infection (SPI), dysplasia, CIS, and invasive carcinoma than in normal cervical epithelium (p=0.001). Despite the strong expression of p16(INK4A) in the area of CIS, no expression of p16(INK4A) was observed in the area of normal epithelium in the vicinity of CIS. 11 cases among 19 cases of examined tissue samples were tested for HPV infection. Seven of them showed positivity for HPV DNA. CONCLUSION: We herein demonstrated that p16(INK4A) would be a sensitive and specific marker for the abnormal cervical cells in tissue sections. This approach will help to reduce interobserver variations in the histopathologic interpretation of cervical biopsy specimens.

With the ever- increasing number of intact aneurysms revealed by modern imaging, the options for their management are assuming greater importance. The surgical management of patients with unruptured intracranial aneurysms continues to be contoversial, and the criteria for withholding treatment or choosing between endovscular embolization and conventional microsurgery are not well delineated. In order to define the surgical result for unruptured intracranial aneurysms, 41 patients(from June 1989 to May 1995) with surgically treated unruptured aneurysms were analyzed. They were categorized as incidental, multiple or aneurysm with mass effect. Subarachnoid hemorrhage from another aneurysm(multiple) was the most common presentation(19 patients). Eleven patients were presented with incidental findings unrelated to aneurysmal subarachnoid hemorrhage or direct aneurysmal mass effect, and 11 patients were presented with mass effect such as cranial nerve palsy or brain stem compression. We could perform direct neck clipping presented with mass effect such as cranial nerve palsy or brain stem compression. We could perform direct neck clipping with without wrapping in 37 patients, trapping in 2, and wrapping in 1. One patient with giant vertebrobasilar artery aneurysm(greater than 25mm in diameter) which was presented with mass effect could not be treated adequately. Instances of morbidity included cranial nerve injury in 4 patients, hemiparesis in 3, hematoma in 2, and major hemispheric infarction in 1. One patient presented with mass effect, died from major hemispheric infarction after surgery of proximal internal carotid artery aneurysm with a size greater than 25mm in diameter. Two patients, who underwent surgery for giant vertebrobasilar artery aneurysms presented with mass effect, were in poor state due to persistent cranial nerve palsy and homiparesis. In general overall outcome was very good. Excellent or good outcome was achieved in 38 patients(92.7%) while 3 patients(7.3%) either died or was/were in poor condition. The aneurysm size was correlated well with the surgical outcome. We have achieved excellent or good out comes in 100% of patients with aneurysms 25mm or less in diameter. However, with aneurysms greater than 25mm in diameter, the outcomes were very poor with 75% of these patients in poor state or dead. "Surgery in unruptured aneurysms?" The answer was "Yes". We believe the size and location of the aneurysm are the key predictons of risk for sugical morbidity.

Sclerosing encapsulating peritonitis (SEP) is characterized by peritoneal fibrosis and adhesion of the peritoneum with the loops of the small intestine. Although the prevalence is low, most cases are caused by peritoneal dialysis, infection, medication, systemic lupus erythematosus (SLE), and intra-abdominal neoplasm. We describe a 22-year old man who was presented with abdominal pain and distension, which were attributed to SLE with peritonitis. He had no specific history of previous medical illness and peritoneal dialysis. He was treated with intravenous high dose methylprednisolone 1 g/day for 3 days, followed by intravenous methylprednisolone 1 mg/kg daily and immunoglobulin. However, his symptoms did not improve. Eventually, a laparoscopic biopsy was performed for an accurate diagnosis. The histopathologic findings were presented in accordance to the typical characteristics of SEP. In spite of medical treatment, he did not show an improvement of clinical symptoms and radiologic findings. As a result, he died from nutritional deficiency, upper gastrointestinal bleeding, and congestive heart failure.

In the absence of hypertension, hypertrophic cardiomyopathy is the most common cause of left ventricular hypertrophy (LVH). However, it has been reported that up to 3% of males with unexplained LVH have Fabry disease, an X-linked disorder of glycophospholipid metabolism that is due to a deficiency in the lysosomal enzyme alpha-galactosidase A (alpha-Gal A). A 44-year-old man was admitted to our hospital with palpitations. He had a history of chronic renal failure diagnosed at age 33 followed by kidney transplantation performed at our institution 2 years later, as well as long-standing hypohidrosis. His medications included prednisolone (5 mg daily), mycophenolate mofetil (1,000 mg, bid), and cyclosporine (150 mg, bid). On hospital day two, an echocardiogram demonstrated increased left ventricular wall thickness (septal wall thickness of 28 mm, posterior wall thickness of 20 mm). Diastolic dysfunction was noted on transmitral flow patterns and tissue Doppler imaging. The patient was found to have low plasma alpha-Gal A activity. A previously reported H46R missense mutation was detected in his alpha-Gal A gene and the patient was subsequently diagnosed with Fabry disease.

BACKGROUND/AIMS: Treatment for cholangitis without common bile duct (CBD) stones has not been established in patients with gallstones. We investigated the usefulness of endoscopic biliary drainage (EBD) without endoscopic sphincterotomy (EST) in patients diagnosed with gallstones and cholangitis without CBD stones by endoscopic retrograde cholangiopancreatography (ERCP) and intraductal ultrasonography (IDUS). METHODS: EBD using 5F plastic stents without EST was performed prospectively in patients with gallstones and cholangitis if CBD stones were not diagnosed by ERCP and IDUS. After ERCP, all patients underwent laparoscopic cholecystectomy. The primary outcomes were clinical and technical success. The secondary outcomes were recurrence rate of biliary events and procedure-related adverse events. RESULTS: Among 187 patients with gallstones and cholangitis, 27 patients without CBD stones according to ERCP and IDUS received EBD using 5F plastic stents without EST. The stents were maintained in all patients until laparoscopic cholecystectomy, and recurrence of cholangitis was not observed. After cholecystectomy, the stents were removed spontaneously in 12 patients and endoscopically in 15 patients. Recurrence of CBD stones was not detected during the follow-up period (median, 421 days). CONCLUSIONS: EBD using 5F plastic stents without EST may be safe and effective for the management of cholangitis accompanied by gallstones in patients without CBD stones according to ERCP and IDUS.

Fasciola hepatica infection may result in biliary obstruction with or without cholangitis in the chronic biliary phase. Because clinical symptoms and signs of F. hepatica are similar to other biliary diseases that cause bile duct obstruction, such as stones or bile duct malignancies, that are, in fact, more common, this condition may not be suspected and diagnosis may be overlooked and delayed. Patients undergoing endoscopic retrograde cholangiopancreatography or endoscopic ultrasonography for the evaluation of bile duct obstruction may be incidentally detected with the worm, and diagnosis can be confirmed by extraction of the leaf-like trematode from the bile duct. Intraductal ultrasonography (IDUS) can provide high-resolution cross-sectional images of the bile duct, and is useful in evaluating indeterminate biliary diseases. We present a case of biliary fascioliasis that was diagnosed using IDUS and managed endoscopically in a patient with acute cholangitis.
