Symptomatic Autonomic Dysfunction in Interstitial Cystitis/Bladder Pain Syndrome.

Importance: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a highly prevalent condition with incompletely understood pathophysiology, especially in relation to the systemic symptoms experienced. The role of autonomic nervous system dysfunction in IC/BPS remains poorly understood.

Objective: The purpose of this study was to assess the relationship between autonomic symptom severity and clinical characteristics of patients with IC/BPS.

Safety and complications of continuation of aspirin therapy in patients undergoing robot-assisted laparoscopic simple prostatectomy.

To evaluate the safety and feasibility of continued perioperative aspirin at the time of robotic assisted simple prostatectomy (RASP). We performed a retrospective review of our IRB approved institutional database of patients who underwent RASP between 2013 and 2022. Comparative groups included patients taking aspirin in the perioperative period and those not taking aspirin pre-operatively.

The role of preoperative immune cell metrics in renal cell carcinoma with a tumor thrombus.

Introduction: The objective of this study was to stratify preoperative immune cell counts by cancer specific outcomes in patients with renal cell carcinoma (RCC) and a tumor thrombus after radical nephrectomy with tumor thrombectomy.

Methods: Patients with a diagnosis of RCC with tumor thrombus that underwent radical nephrectomy with thrombectomy across an international consortium of seven institutions were included. Patients who were metastatic at diagnosis and those who received preoperative medical treatment were also included.

Xeno-free cryopreservation of adherent retinal pigmented epithelium yields viable and functional cells in vitro and in vivo.

Age-related macular degeneration (AMD) is the primary cause of blindness in adults over 60 years of age, and clinical trials are currently assessing the therapeutic potential of retinal pigmented epithelial (RPE) cell monolayers on implantable scaffolds to treat this disease. However, challenges related to the culture, long-term storage, and long-distance transport of such implants currently limit the widespread use of adherent RPE cells as therapeutics. Here we report a xeno-free protocol to cryopreserve a confluent monolayer of clinical-grade, human embryonic stem cell-derived RPE cells on a parylene scaffold (REPS) that yields viable, polarized, and functional RPE cells post-thaw.

Relationship Between Opacity of Cytomegalovirus Retinitis Lesion Borders and Severity of Immunodeficiency Among People With AIDS.

Purpose: To evaluate risk factors for severity of cytomegalovirus (CMV) retinitis lesion whitening (opacity), using a standardized scoring system.

Methods: We performed a cross-sectional, observational investigation of all individuals with newly diagnosed AIDS-related CMV retinitis in three randomized clinical trials and one prospective observational study. Opacity was scored by masked readers, using a prospectively defined ordinal 6-point scale.

CA 19-9 in pancreatic cancer.

CA 19-9 has achieved a defined role in the diagnosis, prognosis, and monitoring of patients with pancreatic cancer. For diagnosis, a reference value above 200 u/mL in a nonjaundiced patient with a confirming CT scan has a very high predictive value. For prognosis, a low preoperative value and a normal value after resection predict a good outcome.

Comparison of preoperative serum CA19-9 levels with results of diagnostic imaging modalities in patients undergoing laparotomy for suspected pancreatic or gallbladder disease.

A prospective, blinded study of CA19-9 in 2,467 patients having abdominal surgery yielded 356 patients with pancreatic, gallbladder, and biliary disease who submitted coded preoperative serum specimens. In this group, there were 84 patients with pancreatic cancer and 24 patients with gallbladder-biliary cancer; the remainder had benign lesions. The recorded imaging data and marker results were merged with the patients' demographic, clinical, and surgical data and tissue diagnoses for analysis.

Diagnostic role of serum CA 19-9 for cholangiocarcinoma in patients with primary sclerosing cholangitis.

Primary sclerosing cholangitis (PSC) predisposes to the development of cholangiocarcinoma, a usually fatal complication that is difficult to diagnose. Serum concentrations of CA 19-9, a tumor-associated antigen, are frequently increased in patients with only cholangiocarcinoma. The aim of this study was to assess the value of an increased serum CA 19-9 level for the diagnosis of cholangiocarcinoma in patients with preexisting PSC.

Evidence for the elevation of serum carcinoembryonic antigen and tumor-associated glycoprotein-72 levels in patients administered interferons.

Sera were collected from 111 patients diagnosed with adenocarcinoma or nonadenocarcinoma malignancies who received different schedules of interferon (IFN)-gamma or IFN-beta ser alone or in combination. Serum carcinoembryonic antigen (CEA) and tumor-associated glycoprotein-72 (TAG-72) antigen levels were measured to determine whether interferon could enhance the tumor shedding and, thereby, the serum level of either tumor antigen. Less than 10% of the sera samples from patients diagnosed with nonadenocarcinoma malignancies (e.

Antibiotics as biological response modifiers.

This review suggests that infections are potent immunomodulators by causing significant alterations in one or more mediators of homeostasis and that an effective antibiosis may be a potent immunomodulator, albeit indirectly. When large numbers of microorganisms are killed, their enzymes and toxins are rapidly released and activate the immune system. The septic syndrome and the potentially progressive states of septic shock, acute respiratory distress syndrome and multiple organ system failure illustrate the biological response modulating (BRM) activity of both infection and antibiotic.

Recombinant interferon-gamma lacks activity against metastatic colorectal cancer but increases serum levels of CA 19-9.

A clinical trial to determine the antitumor activity of recombinant interferon-gamma (rIFN-gamma) was conducted in 36 patients with advanced colorectal cancer. Severe constitutional symptoms were seen in the first five patients who received rIFN-gamma as a 2- to 4-hour intravenous infusion, and this method of administration was therefore abandoned. One transient partial tumor regression was observed in the 31 patients who received treatment by the intramuscular route of administration.

Temporary elevation of CA 125 after abdominal surgical treatment for benign disease and cancer.

Analyses of preoperative and one to seven day postoperative determinations of CA 19-9, carcinoembryonic antigen (CEA) and CA 125 levels in 873 patients indicate that postoperative CA 19-9 and CEA serum levels were within the expected technical variance of the preoperative assay values in patients who were considered to have negative findings (below the reference value) from these tests preoperatively. If the test results were preoperatively positive in patients with cancer, they decreased postoperatively to or below normal reference values, unless the operation was palliative and significant tumor removal was not possible. For patients with a preoperative positive CA 125 level (greater than 35 units per mililiter), the postoperative serum levels were comparable with the CEA and CA 19-9 result.

Comparison of portal and peripheral blood levels of carcinoembryonic antigen, CA 19-9, and CA 125 tumor-associated antigens in patients with colorectal and pancreatic cancer.

Synchronous serum specimens from the systemic and portal circulations of 43 patients with gastrointestinal cancer were assayed for levels of carcinoembryonic antigen, CA 19-9, and CA 125 tumor-associated antigens. The number of patients having a mean ratio of portal to systemic levels greater than 1 and the observed quantity of tumor-associated antigens were significant for carcinoembryonic antigen and CA 125 only in patients with colorectal cancer. No correlations were noted with the surgical stage of disease or with high or low (normal) levels of the three tumor-associated antigens.

T-lymphocyte subsets in patients with idiopathic dilated cardiomyopathy.

T-cell subsets were measured in the peripheral blood of 33 patients with heart failure from idiopathic dilated cardiomyopathy, 22 patients with heart failure from other causes, and 33 normal controls. Mean T-suppressor cell percentage was 30% in normals, 21% in patients with idiopathic dilated cardiomyopathy whose duration of symptoms was less than 1 year (P = 0.0005), and 26% in those with symptoms for greater than 1 year (P = 0.

Preoperative evaluation of serum CA 125 levels in premenopausal and postmenopausal patients with pelvic masses: discrimination of benign from malignant disease.

CA 125 levels were measured in 158 patients with palpable pelvic masses who were about to undergo diagnostic laparotomy. When the 68 patients found to have cancer were compared with the 90 patients with benign disease, those with malignancies were significantly older, were more frequently postmenopausal, and had significantly higher values of serum CA 125. Patients with benign pelvic masses had CA 125 levels greater than 65 U/ml in 8% of cases, whereas those with malignancies had CA 125 levels greater than 65 U/ml in 75% of cases.

An initial analysis of preoperative serum CA 125 levels in patients with early stage ovarian carcinoma.

Preoperative serum CA 125 levels were determined for 36 patients with Stage I and II ovarian carcinoma. Levels ranged from 9 to 1962 U/ml with a mean of 216 U/ml. In Stage I patients, CA 125 levels averaged 133 U/ml and in Stage II patients 382 U/ml.

Repeatedly relapsing disseminated histoplasmosis: clinical observations during long-term follow-up.

We report three patients (followed up for 13, 9, and 12 years) who had multiple episodes of disseminated histoplasmosis. Clinically, all three patients had high yields of positive cultures and all developed corticoadrenal insufficiency; all survived the recurrent relapses. One patient had unilateral progressive panophthalmitis, with ocular cultures positive for Histoplasma capsulatum.

CA 125 in gynecologic practice.

Serum CA 125 levels were determined in 64 women with benign ovarian lesions, 92 women with uterine fundal lesions, and six patients who had negative second-look laparotomy for epithelial ovarian carcinoma. Of those with benign lesions, 13 of 31 patients with endometriosis had levels greater than 35 U/ml. Six of 34 patients with endometrial carcinoma had elevated levels before the primary operation, and six of 15 patients with recurrent endometrial carcinoma had elevated levels.

Clinical trial of recombinant leukocyte A interferon as initial therapy for favorable histology non-Hodgkin's lymphomas and chronic lymphocytic leukemia. An Eastern Cooperative Oncology Group pilot study.

Twenty patients with disseminated favorable histology non-Hodgkin's lymphomas (16 patients) or chronic lymphocytic leukemia (four patients) who had not received previous chemotherapy were treated with recombinant leukocyte A interferon (IFL-rA) (Hoffmann-La Roche, Nutley, NJ). Treatment was administered in a moderate dose (12 X 10(6) U/m2) by intramuscular (IM) injection three times weekly for 8 weeks, followed by weekly maintenance therapy for an additional 16 weeks in patients responding to therapy. Five patients with stable disease at 8 weeks received four additional weeks of three-times-weekly treatment at an escalated dose (25 X 10(6) U/m2).

Treatment of varicella-zoster pneumonia with transfer factor.

A 29-year-old woman with a long history of immunoreactive disease--thrombocytopenic purpura, bullous pemphigoid, nephropathy, and hemolytic anemia--contracted generalized herpes zoster and varicella pneumonia. Respiratory failure requiring assisted respiration accompanied progressive chest findings. She recovered rapidly simultaneous with the administration of transfer factor from a healing herpes zoster patient.

Effect of bacterial immunization on experimental reflux nephropathy.

This study was designed to test the hypothesis that young animals with vesicoureteral reflux might be more vulnerable to renal parenchymal infection by bacteria to which they had not been previously exposed. Forty-four crossbred male piglets had surgical induction of vesicoureteral reflux at 2 weeks of age and introduction of urinary tract infection at 6 weeks. They were sacrificed at 12 weeks of age.

Initial clinical evaluation of an immunoradiometric assay for CA 19-9 using the NCI serum bank.

More than 1,600 coded sera obtained from blood donors and the NCI/Mayo Clinic Serum Bank were analyzed with an improved immunoradiometric assay for the carbohydrate antigenic determinant, CA 19-9. Results indicated that CA 19-9 is elevated in a large fraction of sera (67%) from patients with advanced adenocarcinomas of the upper gastrointestinal (GI) tract, including those with pancreatic, hepatobiliary and gastric carcinomas. Several of these sera had CA 19-9 exceeding 300,000 U/ml.
