Usually, cardiac calcifications are observed in aortic and mitral valves, atrio-ventricular plane, mitral annulus, coronary arteries, pericaridium(usually causing constrictive pericarditis) and cardiac masses. Calcifications of atrial walls are unusual findings that can be identified only using imaging with high spatial resolution, such as cardiac magnetic resonance and computed tomography. We report a case of a 43-year-old patient with no history of heart disease that underwent cardiac evaluation for mild dyspnoea. The echocardiogram showed a calcific aortic valve and a hyper-echogenic lesion located in atrio-ventricular plane. The patient was submitted to cardiac magnetic resonance and to computed tomography imaging to better characterize the localization of mass. The clinical features and location of calcified lesion suggest an infective aetiology causing an endocarditis involving the aortic valve, atrioventricular plane and left atrium. Although we haven't data to support a definite and clear diagnosis, the clinical features and location of the calcified lesion suggest an infective aetiology causing an endocarditis involving the aortic valve, atrio-ventricular plane and left atrium. The patient was followed for 12 mo both clinically and by electrocardiogram and echocardiography without worsening of clinical, electrocardiographic and echocardiographic data. Cardiac magnetic resonance imaging and computed tomography are ideal methods for identifying and following over time patients with calcific degeneration in the heart. 相似文献

Background
Survival with long-term follow-up following liver resection for unresectable colorectal liver metastases (CRLM) downsized by chemotherapy has rarely been reported. The aim of this study was to determine the chance of cure following liver resection for initially unresectable CRLM.Methods
Between January 2000 and December 2009, 61 patients underwent hepatectomy for unresectable liver-only CRLM downsized after chemotherapy. Cure was defined as a recurrence-free interval of at least 5 years after primary hepatectomy.Results
Resectability of CRLM was achieved after a mean number of 11 courses, and 42.6 % of patients underwent liver resection after ≥10 courses. Postoperative mortality was nil, and morbidity rate was 19.7 %. The 5- and 10-year actuarial overall survival rates were 42.6 and 16.0 %. Of 30 patients with a follow-up ≥5 years, 11 were alive, yielding a 5-year actual overall survival rate of 36.7 %, and 7 (23.3 %) were considered cured because they are alive without recurrence. On multivariate analysis, response to chemotherapy was the only independent predictor of both overall and disease-free survival.Conclusions
Cure can be achieved in about 23 % of patients resected for initially unresectable CRLM downsized by chemotherapy. Liver resection can be safely performed in selected patients even after multiple courses of chemotherapy. 相似文献93.
In acute experiments in the rabbit, the amygdaloid nuclear complexes of the two sides were made epileptogenic through electrical stimulation or local injection of penicillin in gel. The effects on the epileptic pattern produced by surgical removal of one of the two epileptogenic amygdalae and the effects of sterotactic lesioning of the region of anterior commissure, head of caudate nucleus, and occipital cortex were analyzed. The occurrence of phenomena of both inhibitory and facilitatory interaction between the two epileptogenic amydalae was confirmed. In some experimental conditions, the restraining influence of an amygdaloid penicillin focus on the contralateral one was quite relevant, and its effect could persist even after surgical removal of the focus from which it originated. The mediation of the interamygdadoid epileptic interaction could not be ascribed to a single cerebral structure or anatomofunctionally homogenous group of structures. The phenomenon appears to involve several structures at different encephalic levels. 相似文献

Purpose
Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique that aims at reducing or abolishing skin incisions and potentially also postoperative pain. The purpose of this study was to analyse operative and long-term results of a series of hybrid transvaginal cholecystectomy. 相似文献96.

MYH9‐related disease (MYH9‐RD) is a rare autosomal dominant disorder caused by mutations in MYH9, the gene encoding the heavy chain of non‐muscle myosin IIA. All patients present congenital macrothrombocytopenia and inclusion bodies in neutrophils. Some of them can also develop sensorineural deafness, presenile cataract, and/or progressive nephropathy leading to end‐stage renal failure. We report four families, each with a novel mutation: two missense mutations, in exons 31 and 32, and two out of frame deletions in exon 40. They were associated with no bleeding diathesis, normal, or only slightly reduced platelet count and no extra‐hematological manifestations, confirming that alterations of the tail domain cause a mild form of MYH9‐RD with no clinically relevant defects. 相似文献

PURPOSE: It has been hypothesized that brain tumors are derived from stem cell or transiently dividing precursor transformation. Furthermore, c-Jun NH(2)-terminal kinases (JNKs) have been involved in gliomagenesis. This study analyzes stem cell marker nestin and JNK expression in glioblastoma multiforme (GBM) and peritumor tissue and assesses their possible prognostic implications. EXPERIMENTAL DESIGN: Nestin and both total JNK (tJNK) and phosphorylated JNK (pJNK) expression was investigated by immunohistochemistry in 20 GBMs. Samples were derived from tumors (first area), from tissues at a distance <1 cm (second area), and between 1 and 3.5 cm (third area) from the macroscopic tumor border. The relationships between patients' age, Karnofsky performance status, gender, protein expression, and survival were analyzed. RESULTS: Nestin cytoplasmic immunoreactivity was observed in the majority of cells in tumor but infrequently in peritumor areas. tJNK, observed in the nucleus and cytoplasm, was widely expressed in the three areas; pJNK, mostly located in the nuclei, was found in a variable percentage of cells in the tumor and peritumor tissue. Nestin and JNK expression in peritumor areas was independent of the presence of neoplastic cells. Univariate analysis indicated that survival was longer (19 versus 12 months; P = 0.01) for patients whose pJNK/nestin and (pJNK/tJNK)/nestin ratios in the second area were > or =2.619 and > or =0.026, respectively. The same variables showed an independent prognostic value in multivariate analysis. CONCLUSIONS: Nestin and JNK expression indicates that peritumor tissue, independently of the presence of neoplastic cells, may present signs of transformation. Moreover, pJNK/nestin and (pJNK/tJNK)/nestin ratios in that tissue seem to have some prognostic implications in GBM patients. 相似文献

Background In advanced gastric cancer few data are available on the efficacy or safety of new drug combination regimens after progression
following first-line chemotherapy.
Methods Patients with histologically confirmed advanced gastric cancer and Eastern Cooperative Oncology Group (ECOG) performance status
(PS) less than 2, progressing after first-line chemotherapy, were eligible. Patients were treated with docetaxel 75 mg/m2 on day 1 and oxaliplatin 80 mg/m2 on day 2, every 3 weeks, until progression or unacceptable toxicity.
Results Between May 2002 and April 2005, 38 patients were enrolled. Men accounted for 73.7% of the patients and the median age was
59 years. The primary tumor was not resected in 47.4% of the patients; the peritoneum was the most frequent metastatic site
(60.5%). The first-line treatment was cisplatin, epirubicin, and infusional 5-fluorouracil (ECF) in 81.5% of the patients
and cisplatin and infusional 5-fluorouracil (CF) in 15.7%. The median number of cycles was 4.3. The treatment was well tolerated,
with no toxic deaths. National Cancer Institute (NCI) grade III-IV neutropenia was frequent (26.3%), but no febrile neutropenia
was reported. Severe asthenia (15.7%) and severe nausea (15.7%) required dose reductions in 2 patients and treatment discontinuation
in another. The overall response rate was 10.5%, and 18 patients (47.3%) experienced disease stabilization (7 of them with
significant clinical benefit). Median time to progression was 4.0 months (range, 2–8 months) and median overall survival was
8.1 months (range, 3–26 months). Thirteen patients (34.2%) also received third-line chemotherapy, with an irinotecan-containing
regimen, and their median overall survival was higher than that of the other patients (16.3 vs 6.0 months)
Conclusion The combination of oxaliplatin and docetaxel shows only marginal activity as second-line treatment, but it has a good tolerability
profile. This suggests that there is room for optimizing the schedule as well as for planning sequential treatments in gastric
cancer. 相似文献

The effects of the cholecystokinin (CCK)-analogue, caerulein, and CCK-receptor antagonist lorglumide (CR-1409) on pancreatic carcinogenesis induced by 7,12-dimethylbenz(a)anthracene (DMBA) were studied. One hundred thirty rats were divided into the following 10 treatment groups: group 1, DMBA (2–3 mg); group 2, DMBA + caerulein (5 μg/kg); group 3, DMBA + caerulein + CR-1409 (12 mg/kg); group 4, caerulein + DMBA; group 5, caerulein + CR-1409 + DMBA; group 6, DMBA + CR-1409; group 7, CR-1409 + DMBA; group 8, caerulein; group 9, CR-1409; and group 10, sham operation + saline. DMBA was surgically implanted into the pancreas. Caerulein and/or CR-1409 was administered twice daily for 15 days after (in groups 2, 3, and 6) or before (in groups 4, 5, and 7) DMBA implantation. Six months after carcinogen administration, all rats were sacrificed and autopsied. The incidence of pancreatic cancer appeared significantly (P < 0.001) increased when caerulein was administered following DMBA implantation. CR-1409 significantly inhibited (P < 0.02) caerulein effects and reduced tumor growth when injected after carcinogen exposure. © 1994 Wiley-Liss, inc. 相似文献
