Combination Treatment of Intratumoral Vidutolimod, Radiosurgery, Nivolumab, and Ipilimumab for Microsatellite Stable Colorectal Carcinoma With Liver Metastases.

Introduction: Microsatellite stable metastatic colorectal cancer (MSS mCRC) is largely refractory to immune checkpoint inhibition. We hypothesized that a combination of intratumoral TLR9 agonist, radiosurgery and dual PD-1 and CTLA-4 blockade would induce a local focus of immune stimulation, evoking a systemic immune response.

Patients And Methods: In this phase I single-institution study, patients with MSS mCRC were treated with a priming dose of s.

Synchronous Malignancies Identified by PET-CT Scan in Breast Cancer Patients.

Breast cancer is a common malignancy and a common cause of cancer-related mortality in women. Pre-treatment workup of breast cancer does not routinely include positron emission tomography scans. We aimed to review cases of women with breast cancer and a synchronous second primary malignancy.

Pericardial covered stent for coronary perforations.

Objectives: To evaluate initial and long term results of coronary perforation treatment with pericardial covered stent.

Background: Iatrogenic coronary perforation is a rare life threatening complication of percutaneous coronary interventions (PCI) occurring in 0.1-0.

Clodronate in myelofibrosis: a case report.

A 59-year-old man had well-documented agnogenic myeloid metaplasia (AMM) with pancytopenia. Frequent blood transfusions were required over a 10-month period. Androgen therapy was not beneficial and treatment with interferon resulted in severe thrombocytopenia with no decrease in transfusion requirements.

Accelerated phase of chronic myeloid leukemia presenting with hypercalcemia and a mediastinal mass.

A patient with chronic myeloid leukemia developed hypercalcemia as a presenting sign of the accelerated phase of the disease. Ultrasound of the neck showed a large hypodense mass connected to the thyroid gland, which was thought to be a parathyroid tumor and the cause of the hypercalcemia. Histology of the surgically removed mass revealed a chloroma.

Static-electric field induction by a silicone cushion for the treatment of hypertrophic and keloid scars.

Silicone gel and silicone occlusive sheeting are widely used at present for the treatment of hypertrophic and keloid scars, without any scientific explanation as to their mode of action. In a recent paper the possibility was raised that static electricity generated by friction-activated silicone sheeting could be the reason for this effect, and that it can, with time, cause involution of hypertrophic and keloid scars. The objective of this study was to test this hypothesis and to observe whether a continuous and also an increased negatively charged static-electric field will shorten the treatment period.

Plasma lipid oxidation and susceptibility of low-density lipoproteins to oxidation in male patients with stable coronary artery disease.

Objectives: Oxidative modifications of low-density lipoproteins (LDL) are considered to be important in the pathogenesis of atherosclerosis. However, the data on the association between LDL oxidation and severity of clinical manifestations of coronary artery disease (CAD) are contradictory. Previous reports were concerned mostly with unstable angina patients.

Observer variation in the interpretation of bone scintigraphy.

To assess the reliability of bone scintigraphy, a random sample of 100 bone scans was reviewed twice by each of two physicians. Observer variation in the description and interpretation of bone scintigrams varied by diagnosis. Good to excellent k values were obtained for inter- and intraobserver variation in relation to metastasis or normal scans.

Amnionitis and premature delivery with intact amniotic membranes involving Staphylococcus aureus. A case report.

Subclinical infection is suspected to be an important etiologic factor in the initiation of preterm labor in women with intact membranes. We present a case of acute clinical chorioamnionitis followed by preterm labor and fetal distress in a woman with intact membranes. The bacteriologic data on the mother and neonate clearly identified coagulase-positive Staphylococcus aureus as the etiologic factor.

Cyfra 21-1. A new potential tumor marker for squamous cell carcinoma of head and neck.

Objective: Evaluation of Cyfra 21-1 (cytokeratin fraction 21-1) in squamous cell carcinoma of the head and neck.

Design: Prospective study.

Patients: Serum Cyfra 21-1 concentration was measured in 250 samples from patients with squamous cell carcinoma of head and neck, patients with benign tumors of head and neck, healthy control subjects, and patients in remission from squamous cell carcinoma of head and neck.

Kidney conservation by delayed contralateral autotransplantation in a case of retroperitoneal lymphoma involving the ureter.

Large-cell retroperitoneal lymphoma was partially resected including a long segment of ureter. The proximal end of the ureter was clipped during surgery. A percutaneous nephrostomy was inserted after 48 h.

Fulminant bilateral cerebellar syndrome in a patient with chronic lymphocytic leukemia.

A 55 year old patient with chronic lymphocytic leukemia (CLL) and long-standing excessive lymphocytosis developed a rapidly progressive neurological syndrome. Differential diagnosis focused on two rate neurological complications in this disease: direct brain infiltration by leukemic cells versus progressive multifocal leukoencephalopathy (PML). Tissue diagnosis was not available.

Erythropoietin-independent colonies of red blood cells and leukocytosis in a worker exposed to low levels of benzene.

Background: Exposure to high levels of benzene commonly results in the suppression of hemopoiesis, although cases of leukocytosis and leukocytosis with thrombocytosis have been reported. No hematologic abnormalities have generally been found with exposure to low levels of benzene.

Methods: A pipe fitter exposed to low levels of benzene (time-weighted average 0.

Usefulness of late potentials on the immediate postoperative signal-averaged electrocardiogram in predicting ventricular tachyarrhythmias early after isolated coronary artery bypass grafting.

The present study was undertaken to determine the value of abnormal late ventricular potentials on signal-averaged electrocardiograms (ECG) in identifying patients at risk of developing ventricular tachycardia or ventricular fibrillation in the early postoperative period after coronary artery bypass grafting. Signal-averaged ECGs were recorded immediately after operation in 72 patients. Abnormal late potentials were defined as the presence of 2 or 3 of the following: (1) root-mean-square amplitude of the last 40 ms of the QRS < 20 microV; (2) duration of the terminal QRS potentials (after 40 microV) > or = 39 ms; and (3) high-frequency QRS duration > 120 ms (in patients with conduction defects, only the first 2 criteria were used).

Structure and possible biological roles of Lp(a).

Lipoprotein(a) [Lp(a)] is a plasma macromolecular complex that is assembled from low-density lipoproteins (LDL) and a large hydrophilic glycoprotein, named apolipoprotein(a) [apo(a)], linked by a disulfide bond to apolipoprotein B-100. Apo(a) is formed by different structural domains one of which is present in multiple copies, the number of which is determined by variation in the hypervariable apo(a) gene. Sequence homology of apo(a) with plasminogen may explain the competition of Lp(a) for some physiological functions of plasminogen in the coagulation and fibrinolytic cascade in vitro.

Lysine-binding species of lipoprotein(a) in coronary artery disease.

Elevated levels of plasma lipoprotein(a) [Lp(a)] have frequently been associated with coronary artery disease (CAD). Recently Lp(a) was fractionated into two species with different affinities for Lysine-Sepharose. The influence of lysine-binding heterogeneity of Lp(a) on its cardiovascular pathogenicity has not previously been studied.

Improved criteria for localization of coronary artery disease from the exercise electrocardiogram.

To derive better criteria for the noninvasive localization of coronary artery disease, a 12-lead computer-averaged rest and exercise electrocardiogram was examined in 44 selected patients (34 men, 10 women) with single-vessel disease who had an exercise test positive for ischemia by established criteria. Left anterior descending disease was characterized by S-T segment elevation (> or = 0.05 mV) in lead V1 [sensitivity (S) 71%, specificity (Sp) 100%], a T wave amplitude increase in V1 (S 88%, Sp 73%) and a leftward shift or no change in mean frontal plane QRS axis (AQRS; S 92%, Sp 93%).

[The benefit of combined therapy with captopril and nitrates in severe congestive heart failure].

We compared the acute hemodynamic effects of captopril and nitrates in 11 patients with severe congestive heart failure and grade IV cardiac disability. Pressures were measured using a Swan-Ganz catheter system; cardiac output and stroke index were measured by thermodilution, and left-ventricular (LV) volumes and ejection fraction were calculated simultaneously with the hemodynamic measurements from radionuclide ventriculography. Measurements were made in each of 4 treatment states: control, sublingual isosorbide dinitrate (ISDN; 5 and 15 mg), oral captopril (50-200 mg daily) and during combined therapy with captopril and ISDN.

Doppler diastolic transmitral flow patterns in severe heart failure: response to controlled changes in filling pressure using intravenous isosorbide dinitrate.

Serial Doppler diastolic transmitral flow patterns were compared with simultaneous hemodynamic measurements in a homogeneous group of patients with severe (New York Heart Association class 4) heart failure who were receiving high dose (508 +/- 271 micrograms/min) intravenous isosorbide dinitrate. The Doppler tracing uniformly showed a severe restrictive pattern, with tall peak early diastolic filling (E) wave (84 +/- 12 cm/s), small late filling (A) wave (28 +/- 8 cm/s) and very high E/A ratio (3.2 +/- 0.

Use and limitations of Holter electrocardiography in assessing drug therapy of myocardial ischemia during the peri-PTCA period.

Incidence and pattern of myocardial ischemia during the peri-PTCA (percutaneous transluminal coronary angioplasty) period and the possible role of continuous intravenous isosorbide dinitrate in its prevention were examined prospectively in 30 patients. Holter electrocardiographic monitoring was performed for 21 +/- 3 h before PTCA and continued during and for 41 +/- 8 h after the procedure. Before PTCA, 19 ischemic episodes were present in 10 (33%) of 30 patients.

Effects of time, sex, ethnic origin, and area of residence on prevalence of asthma in Israeli adolescents.

Objectives: To study effects of time, sex, ethnic origin, and area of residence on prevalence of asthma in Israeli adolescents.

Design: Retrospective survey of asthma from computerised medical draft records of conscripts examined up to the end of 1989.

Setting: Five regional centres in Israel.

Soluble factors from peripheral blood T-cells of patients with polycythemia vera stimulate normal BFU-E.

T cells and monocytes from patients with polycythemia vera (PV) were isolated and grown in culture. The conditioned medium was tested for the presence of soluble factors that promote proliferation of erythroid colonies from the blood of healthy donors. We show that T cells from all 14 PV patients that were examined secrete factor/s that stimulate the proliferation of erythroid burst-forming units (BFU-E) in the absence of an external source of erythropoietin and BPA.
