Here we report median and common peroneal nerve SEPs in a patient with tabes dorsalis. SEPs were within normal limits following
median nerve stimulation, but of prolonged latency for common peroneal nerve. This was in keeping with clinical findings of
posterior column involvement confined to the lumbosacral tract and with pathological features of tabetic neurosyphilis.
Sommario Gli autori riportano le caratteristiche dei potenziali evocati somatosensoriali del nervo mediano e peroneo comune in un paziente affetto da tabe dorsale. I potenziali evocati somatosensoriali sono risultati nei limiti della norma stimolando il nervo mediano ma di latenza aumentata per il nervo peroneo comune. Ciò risultava in accordo sia con le caratteristiche cliniche di segni di interessamento dei cordoni posteriori limitato al tratto lombosacrale che con le caratteristiche anatomopatologiche della neurosifilide.相似文献

Postoperative cholangitis is a frequent
and unpredictable complication of unknown etiology following bile duct
reconstruction (BDR), particularly for biliary atresia. This study was
undertaken to correlate the growth of bacteria in the
hepaticojejunostomy with that in the liver after BDR. Quantitative
bacterial culture was done on the specimens taken from the liver and
from the hepaticojejunostomy at 1 week (group 1, n = 7), 1 month
(group 2, n = 7), and 2 months (group 3, n = 7) following BDR
with Roux-en-Y hepaticojejunostomy in piglets after 2 weeks of common
bile duct ligation. The histological examination of the liver and the
hepaticojejunostomy, as well as serial monitoring of hemogram and liver
function tests, were performed to correlate the findings with the
bacterial concentration of the liver and the hepaticojejunostomy
following BDR. The bacterial concentration of the hepaticojejunostomy,
expressed as log10 colony-forming units per gram
(log10 CFU/g) of the hepaticojejunostomy, showed a
progressive decrease from 8.38 ± 1.36 in group 1, 7.07 ±
2.54 in group 2, to 3.56 ± 1.31 in group 3 (p =
0.001). The log10 CFU/g of the liver also showed a
progressive decrease from 5.02 ± 1.59 in group 1, 3.16 ±
1.56 in group 2, to 2.19 ± 1.09 in group 3 (p =
0.006). There was a significant positive correlation of the
log10 CFU/g of the liver (n = 21) with that of the
hepaticojejunostomy (n = 21) following BDR (r = 0.600,
p = 0.004). Most of the infectious pathogens isolated
from the liver were also isolated from the hepaticojejunostomy. The
changes in hemoglobin, bilirubin, albumin, and ammonia significantly
correlated with the changes of the bacterial concentration of the
liver. The results of the study suggests that hepatic bacterial
proliferation after BDR is significantly affected by microbial
overgrowth in the bilioenteric anastomosis and is associated with
deteriorated liver function and hemogram. 相似文献

Pancreatic Solid-cystic-papillary Tumor: Clinicopathologic Features in Eight Patients from Hong Kong and Review of the Literature 总被引:43,自引:1,他引:42
Solid-cystic-papillary tumors (SCPTs) of the pancreas are rare. The clinicopathologic features and pathogenesis of these
tumors have attracted a number of investigations, but the results remain unclear. We investigated the clinicopathologic data,
immunohistochemical expression of the pan-endocrine markers, hormones, steroid receptors, and p53 overexpression in pancreatic
SCPTs from eight Chinese patients (seven women, one man) collected over a 24-year period. They accounted for 2.5% of the primary
pancreatic tumors. The tumors were seen in young women (mean age 27 years). They were large (mean size of resected tumor was
8.4 cm), benign, had solid and cystic areas, and were evenly distributed in the pancreas. The main differential diagnosis
was pancreatic endocrine tumor. The tumors were negative for pan-endocrine markers, hormones, estrogen receptor, progesterone
receptor, and p53. To date, 452 pancreatic SCPTs have been documented in the English literature. They occurred in patients
of different ethnic groups, particularly in non-Caucasians. The tumors were frequently noted in young females. Uncommon cases
of malignant pancreatic SCPTs were often found in older men and had indolent behavior. It was concluded that pancreatic SCPTs
have distinct clinicopathologic characteristics. The present observations, together with a review of the literature suggests
that overexpression of p53 or estrogen receptor is not important in the pathogenesis of pancreatic SCPTs. 相似文献

The effect of positively charged liposomes on the stability of negatively charged indomethacin particle suspensions was investigated by adsorption, microelectrophoresis, sedimentation volume, and redispersibility. It was found that flocculation occurred in the neighborhood of the zero point of charge of the liposome:indomethacin suspensions. This resulted from the operation of van der Waals attraction under the condition of nil electrostatic repulsion. Correlation among the results of adsorption, microelectrophoresis, sedimentation volume, and redispersibility was good. The mixing effect of the suspension was examined by microelectrophoresis and confirmed by sedimentation volume and redispersibility. Results indicate that there was no difference between the method of dilution of the liposome:indomethacin concentrated suspension after mixing and the method of dilution of liposomes prior to mixing with the indomethacin suspension. This was due to interaction depending on the charge density of the particles. 相似文献

The Italian Registry of Off-Therapy patients after childhood tumors now includes 760 subjects with acute lymphoblastic leukemia. These patients were all removed from treatment by December 31, 1981, and were followed in 35 different institutions. All the children have received multiple-drug treatment, combined, in 79.7% of the cases, with cranial irradiation. Thirty-nine (5%) experienced a relapse before treatment suspension. Total duration of antileukemic therapy ranges between 18 and 131 months (median, 38). At the last updating (December 31, 1981), 699 subjects were alive, 6 were lost to follow-up, and 55 had died. Life-table analysis shows that 90.8% were alive and 77% were alive in continuous complete remission at 36 months, whereas at 66 months, the cumulative proportions were 88% and 75.5%, respectively. One hundred thirty-six of 760 relapses after therapy suspension were reported: 83 in male patients and 53 in female patients (P less than 0.01). The longest interval between relapse and treatment suspension was 64 months. Six of 55 died in continuous complete remission 3 to 44 months after treatment suspension. Five births of apparently normal babies to female patients have been reported. A general outline of the project and the future program are given. 相似文献

To define the prevalence of Hepatitis C Virus (HCV) infection in patients with chronic hepatitis or cirrhosis of any aetiology, we tested a group of 372 consecutive subjects with biopsy-proven chronic liver disease (CLD) for anti-HCV antibodies, excluding active drug-addicts and alcoholics. Our results show that in Southern Italy HCV infection is widespread among subjects with cryptogenic chronic liver disease, as well as in liver diseases with features of autoimmunity (71.7% and 66.7% anti-HCV positive, respectively). Anti-HCV is infrequent among non drug-addicted HBsAg positive subjects (4.7%), and bears no relation to hepatitis D superinfection. Subjects with CLD and a history of parenteral exposure are almost always anti-HCV positive (89.2%). Patients with HBV-related CLD and previous drug-addicts are on the average younger than other disease groups, irrespective of their HCV status. Among subjects whose CLD is related to parenteral exposure, cryptogenic or autoimmune no increase in the rate of anti-HCV positivity seems to bear a parallel relationship to age. No known risk factor for parenteral transmission, other than use of blood or blood products and previous drug-addiction, can be clearly related to HCV infection. No trend to familiar clustering of HCV-induced liver disease is apparent. Liver disease severity, as assessed by transaminase levels and liver histology, does not correlate to anti-HCV status. 相似文献
