BACKGROUND/AIMS: We investigated the relationship between percutaneous papillary balloon dilatation (PPBD) and hyperamylasemia after PPBD. METHODOLOGY: We studied the rate of pancreatitis and asymptomatic hyperamylasemia after PPBD for choledocholithiasis in 64 symptomatic patients. Pancreatitis was defined as epigastric pain combined with at least a 3-fold rise in serum amylase at 24 hours after PPBD. Asymptomatic hyperamylasemia was defined as a rise in serum amylase (normal range, 50 to 160 IU/L) without epigastric pain. RESULTS: The stones were successfully pushed out into the duodenum in all patients. Three patients developed post-PPBD pancreatitis, graded moderate in one and mild in two. Serum amylase values were elevated over the normal upper limit in 21 patients, 33%, over 3-fold in 10, 16% over 1000 IU/L in 6, 9%. Asymptomatic hyperamylasemia was observed in 18 patients. The amylase value after PPBD was elevated to more than 160 IU/L in 44% (17/39) of patients 80 years old or under vs. 16% (4/25) of patients older than 80 and in 23% (10/44) of patients with intrahepatic bile duct dilatation on admission vs. 55% (11/20) of patients without it, with a significant difference, respectively (p<0.05). The amylase value after PPBD was elevated to more than 1000 IU/L in 15% (6/39) of patients 80 years old or under vs. 0% (0/25) of patients older than 80 and in 29% (4/14) of patients with bile duct stones having a horizontal diameter of 8mm or smaller and 4% (2/50) of patients with stones larger than 8mm (p < 0.05 and p<0.01, respectively). CONCLUSIONS: We believe that postoperative continuous decompression of the bile duct by PPBD is reliable and that it contributed to the prevention of severe pancreatitis. We conclude that PPBD can be performed more safely in symptomatic patients older than 80 with choledocholithiasis with intrahepatic bile duct dilatation at the time of admission. 相似文献
BackgroundWe report on a unique complication of cerebellar ataxia and motor neuron disease named Asidan/SCA36 with a high frequency of tongue atrophy. We aimed to elucidate dysphagia in amyotrophic lateral sclerosis (ALS) and spinal, bulbar muscular atrophy (SBMA), and Asidan/SCA36 patients with new methods.MethodsPatients diagnosed with ALS (n = 20), SBMA (n = 6), and Asidan (n = 12) were included. A videofluoroscopic swallow study (VFS), an assessment of maximal tongue pressure (MTP), and impedance pharyngography (IPG) were applied.ResultsThe frequencies of VFS abnormalities were 70%, 50%, and 33% in ALS, SBMA, and Asidan/SCA36, respectively. Compared with control subjects (31.6 ± 6.3 kPa, mean ± SD), MTP was significantly decreased in ALS patients and SBMA patients, but was relatively preserved in Asidan patients. ALS patients performed more swallowing actions (Ns) detected by IPG than did control subjects, but SBMA and Asidan/SCA36 patients performed similar Ns to control subjects.ConclusionsVFS showed a higher frequency of swallowing abnormalities in ALS patients. MTP and IPG measurements showed the most severe involvement in ALS patients and a relatively preserved swallowing function in SBMA and Asidan/SCA36 patients. 相似文献
The envelope proteins of the hepatitis C virus (HCV), E1 and E2, have been revealed to be essential for invasion of HCV. Thus, we were engaged in the search for the inhibitors against HCV invasion through the assay system using the model virus expressing recombinant HCV envelopes, E1 and E2. Now, we disclosed dimeric hydrolysable tannin oenothein B (1) from MeOH extract of Oenothera erythrosepala as an active principle for inhibition of HCV invasion and its potency was almost the same as that of monomeric hydrolysable tannin, tellimagrandin I (2). Furthermore, by use of stereoselectively prepared 1-β- and 1-α-O-methyl tellimagrandin Is (4 and 5), the introduction of methyl moiety into 1-hydroxy group of 2 was clarified to result in slightly reduction of activity and β-isomer was revealed to exhibit a little stronger activity than α-one.
It is crucial to identify risk factors for life prognosis after hepatitis C virus (HCV) eradication among patients with or without a high risk of liver cancer or complications.
Methods
This is a prospective, multicenter and observational study using the database of 1031 patients after HCV eradication by direct-acting antiviral agents (DAAs) to evaluate the development of hepatocellular carcinoma (HCC) and patients’ survival after a sustained virological response (SVR). The Cox proportional hazards regression model was used to estimate hazard ratios associated with HCC development and survival.
Results
AFP at SVR was significantly associated with HCC recurrence in the adjusted model. Liver fibrosis, Mac-2 binding protein glycosylation isomer (M2BPGi) at SVR and smoking status before treatment were positively associated with the development of HCC and M2BPGi was positively associated with HCC recurrence, although not reaching statistical significance. Among patients without a history of HCC, M2BPGi and estimated glomerular filtration rate (eGFR) at SVR were significantly associated with death after viral eradication [M2BPGi (HR 4.07, 95% CI 1.22, 13.57), eGFR (HR 0.97, 95% CI 0.94, 0.99)]. Strikingly, of 16 patients who died, among participants without a history of HCC, only two died of liver cancer associated with HCV, whereas 11 died of non-HCV- related cancer or cardiovascular diseases.
Conclusion
M2BPGi at SVR is a potential predictor for patients’ survival and a candidate biomarker for detecting individuals who are at greater risk of death due to cancer-related and unrelated to HCV, as well as cardiovascular diseases, after viral eradication.
Causative agent identification is important in the treatment of poisoning. We report the case of a patient who presented with an altered level of consciousness after drinking a fluorescent pink liquid. Upon measuring the anion gap and urinary calcium oxalate level, the patient was diagnosed with early ethylene glycol poisoning. 相似文献
