JOURNAL FREE ACCESSCold snare excision (CSE) has proved to be an effective method for the destruction of diminutive polyps of the colon and rectum. We investigated the correlation between polyp size and bleeding time at the resected end after CSE, and also an appropriate measuring method using CSE. Eighty patients with single polyps were examined. Each polyp was identified as being 5 mm in diameter or smaller using the open-biopsy forceps technique (OBFT). The size of the polyp was calculated using our measuring system (SMS). Of the polyps identified as being 5 mm in diameter or less using OBFT, 15% were 6 mm or more using the SMS. CSE was performed for each polyp, and the time taken for the hemostasis (bleeding time of the CSE; BTCSE) was determined. In seventy-seven polyps that were 6 mm or smaller in SMS, a correlation was noted between SMS and BTCSE. In three polyps that were 7 mm or more by SMS, hemostasis took 10 min or more after CSE, and required electrocoagulation. These results suggest that CSE is a safe method for the removal of polyps determined to be 6 mm in diameter or smaller using the SMS.View full abstractDownload PDF (340K) -

JOURNAL FREE ACCESSWe report a study of polymorphism for seven short tandem repeat (STR) loci in Japanese and Chinese populations. Among 104 to 134 individuals in the both population samples, eight alleles were revealed for locus PLA2, thirteen for D3S1359, eleven for FGA, eight for D8S315 (kw38), ten for D8S1132, five for CYP19, and seven for D3S2459. They correspondingly constituted 10 to 39 genotypes therein. For most of the STRs, there was only a single allele active as the most frequent one among the others, except locus D3S1359 in Chinese samples (two alleles, 206 bp and 210 bp, frequency=0.273 each). Also, the population genotype configurations were locus specific, varying in the patterns of commonest genotypes on each locus, e.g., one pattern for loci CYP19, D3S1359, and D8S315, one and two for loci PLA2 and D3S2459, two for locus D8S1132, and one and four for locus FGA. The distributions of observed genotypes were in Hardy-Weinberg Equilibrium. Furthermore, the seven STRs were exhibited highly polymorphic and informative for the both populations, and the alleles could be easily separated in electrophoresis and correctly interpreted with side-to-side allelic ladders. Together, the results suggest that the tri- and tetra-meric STRs are useful genetic markers for forensic practice.View full abstractDownload PDF (611K) -

JOURNAL FREE ACCESSBecause pulmonary embolism is often silent, simple clinical procedures are desirable to identify patients with a low to intermediate probability of pulmonary embolism. Among 19 467 patients managed under general anesthesia, we had one bile tract surgery case and three neurosurgical cases whose silent pulmonary embolism was initially suggested by an increase in the arterial to end-tidal CO2 gradient (from 17 to 27 mmHg) after general anesthesia was induced or their trachea was intubated. During the preoperative assessment, the patients presented no clinical manifestations suggestive of pulmonary embolism. Our initial diagnosis was confirmed by scintigraphy and/or angiography done immediately after the operations. Because capnometry has been shown to be applicable to non-intubated, spontaneously breathing patients, we suggest that measuring the gradient may serve as an additional method for unmasking silent pulmonary embolism in patients at risk or with disturbed consciousness, whether they are scheduled for operations or not.View full abstractDownload PDF (1580K) -

JOURNAL FREE ACCESSWe investigated the effects of pre-treatment with dibutyryl cAMP (db-cAMP) or cGMP on endotoxin-induced hemodynamic changes and pulmonary vascular permeability in isolated perfused rat lungs. Intraperitoneal injection of Salmonella enteritidis endotoxin (2 mg/kg) caused increases in pulmonary arterial resistance (Ra) after venous reservoir elevation, in pulmonary filtration coefficient (Kf) and in lung wet-to-dry (W/D) weight ratio. Pre-treatment with db-cAMP blocked endotoxin-induced increases in Ra, Kf and W/D weight ratio. Pre-treatment with cGMP attenuated only the increase in Ra caused by endotoxin. Moreover, administration of db-cAMP 2 hours after endotoxin injection attenuated the increase in Ra induced by endotoxin treatment. The increases in Kf and W/D weight ratio caused by endotoxin were not affected by post-treatment with db-cAMP. Since the increases in Ra, Kf and W/D weight ratio caused by endotoxin were blocked by pre-treatment with db-cAMP, agents that increase intracellular cAMP level may be useful to prevent acute pulmonary vascular injury.View full abstractDownload PDF (656K) -

JOURNAL FREE ACCESSIn this study, the effect of haloperidol on histamine (HA) levels, histidine decarboxylase (HDC) activities and the bindings of [3H]-(R)-α-methylhistamine ([3H]-(R)-α-MeHA) to histamine H3 receptors were investigated in the rat brain. Administration of 10 mg/kg of haloperidol decreased HA levels in the rat striatum and diencephalon, but increased HDC activities in rat striatum and diencephalon, although that of 5 mg/kg did not change them. Meanwhile, haloperidol inhibited the bindings of [3H]-(R)-α-MeHA to H3 receptor sites in the rat striatal membrane with a Ki value of 10.5±0.45 μM. These findings suggest that only a high dose of haloperidol increases HA synthesis and release as a histamine H3 receptor antagonist in the rat brain.View full abstractDownload PDF (496K)

JOURNAL FREE ACCESSA case of a 96-year-old male with a foreign body in the larynx is reported. The foreign body was a press-through-pack (PTP), a plastic packing for medicine, 16 mm×16 mm×3 mm in size. The PTP was safely removed from the larynx under general anesthesia.View full abstractDownload PDF (653K) -

JOURNAL FREE ACCESSWe describe a patient with acute myelogenous leukemia (AML) with t(16 ; 21)(p11 ; q22) translocation, whose minimal residual disease (MRD) both in cerebrospinal fluid (CSF) and bone marrow (BM) was monitored by reverse transcriptase-polymerase chain reaction (RT-PCR). A TLS/ERG-FUS fusion transcript, which is known to be expressed by t(16 ; 21)(p11 ; q22) translocation, was detectable by RT-PCR both in BM and CSF cells in the first complete remission, suggesting the existence of MRD. The disease relapsed 6 months after its onset and allogeneic peripheral blood stem cell transplantation (PBSCT) was undergone. A TLS/ERG-FUS fusion transcript became rapidly below the detection level after PBSCT. These findings suggest the usefulness of RT-PCR for the detection of MRD in CSF, which contains a limited number of cells, as well as BM.View full abstractDownload PDF (716K) -

JOURNAL FREE ACCESSA 48-year-old man suffering from paraparesis had congenital kyphoscoliosis due to fused wedged vertebrae between T2 and T4. The kyphoscoliosis consisted of left convex scoliosis measuring 26 degrees and kyphosis measuring 27 degrees. On CT-myelograms and axial MR images, the dura and spinal cord were deviated anterolaterally to the concave side of the curve around its apex. The spinal cord was stuck and flattened against the posterolateral margin of the vertebral body to the base of the pedicle with the posterior subarachnoid space preserved. Anterior decompression from the concave side through a transthoracic approach resulted in a remarkable neurological improvement. The paraparesis may have been caused by compression of the spinal cord through a tethering effect due to its developmental tightness around the apical vertebra and the additional tension created by motions of the neck.View full abstractDownload PDF (2728K)
