VALUE OF COMPUTED TOMOGRAPHY FOR EVALUATING THE INJECTION SITE IN ENDOSONOGRAPHY‐GUIDED CELIAC PLEXUS NEUROLYSIS

Endosonography‐guided celiac plexus neurolysis (EUS‐CPN) safely and effectively relieves pain associated with intra‐abdominal malignancies when the neurolytic is accurately injected. We applied contrast medium to evaluate the ethanol injection sites in patients who received EUS‐CPN due to abdominal pain caused by malignancies. We injected, under the guidance of endoscopic ultrasonography (EUS), ethanol containing 10% contrast medium into the celiac plexus of patients with intra‐abdominal pain due to malignancies. Immediately after the endoscopic therapy, patients underwent computed tomography (CT) to confirm the injection site. Images of distribution of injected solutions were classified into three groups. Injected solution dispersed in unilateral and bilateral anterocrural space was defined as ‘unilateral injection’ or ‘bilateral injection’, respectively. Injected solution located out of the anterocrural space was defined as ‘inappropriate injection’. Pre‐ and postprocedure pain was assessed using a standard analog scale. Before and 2, 4, 8, 12, and 16 weeks after the procedure, pain scores were evaluated. From April 2003 to May 2005, 13 patients were enrolled in this study. Improvement of pain score in the ‘bilateral injection’ and ‘unilateral injection’ groups was significantly superior to the change in the ‘inappropriate injection’ group. Although EUS‐CPN was effective in eight of 13 patients (61.5%), additional EUS‐CPN to the ‘inappropriate injection group’ increased the response rate to 84.6%. Injection of ethanol to the anterocrural space by EUS‐CPN produced adequate pain relief. Immediate examination by CT for confirmation of injection sites after EUS‐CPN would increase the likelihood of induction of pain relief.     

Significance of fiberoptic bronchoscopy after pulmonary resection of lung cancer for early detection in second lung cancer

By the end of 1988, seventy five cases after pulmonary resection for lung cancer and one case after pulmonary resection for basal cell hyperplasia were examined with fiberoptic bronchoscopy as postoperative follow up. Endobronchial tumor was detected in 14 cases. In seven cases, endobronchial tumor was located at site far from the surgical bronchial anastomosis. These tumors were suspected as second lung cancer as long as examined by fiberoptic bronchoscopy. Histological type of all of these was squamous cell carcinoma. Re-operations were performed in five cases and two of them were early lung cancer. In 6 cases (13.6%) among 44 cases examined with fiberoptic bronchoscopy after pulmonary resection for central type squamous cell carcinoma, second lung cancer was detected. In the case of central type squamous cell carcinoma, usually the tumor appears to be of same histological type and at same location. Among those cases those who smoke heavily should be separated as high risk group. If this group is followed with fiberoptic bronchoscopy or sputum cytological examination, it is more possible to detect second lung cancer at an early stage.     

No evidence for association between the −112G/A polymorphism of UGRP1 and childhood atopic asthma

BACKGROUND: Susceptibility to asthma is known to involve genetic factors. Genome-wide screens have indicated that the chromosome 5q31-q34 region is linked to and/or associated with asthma. A new gene, named UGRP1 and reported by Niimi et al., encodes uteroglobin-related protein and is expressed in the lung and trachea. Niimi et al. showed the -112G/A polymorphism of the UGRP1 gene to be associated with asthma in a case-control study. OBJECTIVE: The objective of the present study was to replicate this association and confirm the possible role of the UGRP1-112G/A polymorphism in the aetiology of childhood asthma in a Japanese population. METHODS AND RESULTS: We conducted a transmission disequilibrium test (TDT) in 131 families identified through paediatric patients being treated for asthma. A case-control study was also carried out by comparing the probands and 137 unrelated non-atopic non-asthmatic Japanese children and 211 unrelated healthy Japanese adults. The -112G/A polymorphism was genotyped by the PCR-RFLP method. The TDT revealed that the -112A allele was not preferentially transmitted to asthma-affected children (P=0.85). Neither the presence of at least one A allele in an individual's genotype (sum of the G/A and A/A genotypes) nor the -112A allele was more prevalent among the asthma subjects than among the control subjects. CONCLUSION: Our findings indicate that the UGRP1-112G/A polymorphism does not play a substantial role in genetic predisposition to childhood asthma in this Japanese population.     

Research in similarities between EEP34 and lipocortin

EDTA-extractable protein (EEP) is a major extrinsic protein of lens fiber membrane. The EEP of calf lens separated three major bands by SDS-PAGE, and the molecular weights of these major bands were 34 kilodalton (kd.), 33 kd. and 32 kd. Combination of EEP with F-actin and some kinds of phospholipid containing liposomes depends on Ca2+. In two-dimensional gel electrophoresis, some spots of the calf-EEP partially overlapped with spots of lipocortin, which is a substrate for epidermal growth factor receptor/kinase and an inhibitor of phospholipase A2. The 34 kd. protein of the EEP cross-reacted to the antibody prepared against lipocortin of pig's aorta: These results suggest the important function of EEP in lens.     

A Case of Pelvic Osteomyelitis

A patient presenting with osteomyelitis of the pelvis is described. In this case it was difficult to establish a correct diagnosis by use of scintigraphic scanning, in spite of clear roentgenographic evidence of osteomyelitis.     

Thrombopoietin in postoperative thrombocytopenia following living donor hepatectomy.

Thrombocytopenia is a frequent finding following living donor hepatectomy. It appears more pronounced in right graft donors than in left graft donors. This study analyzed postoperative thrombocytopenia in 20 living liver donors and examined the change of endogenous thrombopoietin (TPO) in its recovery. Platelet count, TPO level, fibrinogen degradation product (FDP), and D-Dimer were measured before surgery and on postoperative days (PODs) 1, 2, 3, 5, 7, and 14. Concurrently, liver and spleen volumes were calculated by computed tomography. Platelet count on POD 3 was significantly lower in right graft donors than in left graft donors (13.0 +/- 3.7 x 10(4)/microL vs. 16.8 +/- 4.0 x 10(4)/microL, P = 0.039) but recovered by POD 7 in all donors. Postoperative elevations of FDP and D-Dimer were significantly higher in right graft donors than in left graft donors. TPO level rose immediately after surgery, peaked on POD 5 in left graft donors and on POD 7 in right graft donors, and fell nearly to preoperative levels by POD 14. Postoperative TPO level per liver volume was significantly higher in right graft donors than in left graft donors. In conclusion, thrombocytopenia following living donor hepatectomy resolved within the first week regardless of graft type and was mainly associated with increasing consumption of circulating platelets, possibly due to intrahepatic and splenic congestion. With a reduced number of circulating platelets, TPO level rapidly increases. Also, with reduced consumption of platelets related to recovery from surgery, thrombocytopenia should resolve. As a consequence, TPO level would be expected to fall.
