Abstract

The emergency department (ED) may represent a missed opportunity to proactively intervene upon patients at "high risk" for HIV. We sought to describe characteristics of ED HIV seroconverters (individuals who screened positive in the ED for HIV who had either (1) a previous prior negative HIV test in the electronic health record (EHR) or who (2) self-reported a prior negative HIV test) to identify a "high-risk" phenotype for pre-infection engagement. A retrospective chart-review was performed of HIV seroconverters at an academic, urban ED. General demographics, mental health illness comorbidities, and Centers for Disease Control and Prevention (CDC)-identified "high risk" factors, including intravenous drug use (IVDU) and history of sexually transmitted infection (STI) were noted. One hundred thirty total patients were identified, 48 (36.9%) with prior HER-negative test and 82 (63.1%) with self-reported previous negative test. Of total seroconverters: 100 (76.9%) were male and 77 (59.2%) were between the ages of 13-34, comparable to national rates of new HIV diagnoses. Ninety-two patients (70.8%) were Black and 16 (12.3%) had a history of IVDU, significantly increased compared with regional and national new HIV rates (

Abstract

Background . Stage III advanced locoregional esophageal carcinoma is frequently unresectable and inconsistently represented in therapeutic trials of esophageal cancer. Methods . From 1992 to 1998, 34 of 131 total esophageal cancer patients were designated stage III (16 T3N1, 9 T4N0, 9 T4N1) and medically fit to enter a combined modality protocol with continuous infusion 5-fluorouracil (CI5-FU, 300 to 600 mg/m 2 /day), high-dose external beam irradiation (60 Gy), and interval esophagectomy. Staging before and after induction therapy included computed tomography, endoscopy, and endoscopic ultrasound. Results . Significant toxicity from induction therapy included death (5/34; 14.7%), pneumonitis (5/34; 14.7%), mucositis (13/34; 38%), and hand-foot syndrome (3/34; 8.8%). In addition to the five deaths, 11 patients did not proceed to operation because of development of esophagorespiratory fistula in 3, distant disease in 2, persistence of T4 stage in 2, progression of comorbidities in 2, and patient refusal in 2. There was a discrepancy between clinical complete response (cCR) at restaging 56% (19/34) and pathologic CR (pCR) noted at the time of operation (8/34; 23.5%). Complete resections were possible in 16 of 18 patients explored. Complications in 4 patients included: death (1), airway injury (1), chylothorax requiring reoperation (1), anastomotic leak (1), recurrent nerve injury with vocal cord paresis (2), and ascaris infection (1). Actuarial survival analysis using the Kaplan-Meier method and log-rank testing showed a 36-month survival of 20% for the group as a whole and 27% for patients restaged cCR (cCR vs PR, p = 0.0046). Treatment failure is predominantly distant, with good local control in resected patients. N0 node status was strongly associated with survival (N0 vs N1 p = 0.0024). There is a trend towards improved survival in the resected group (resected 22% vs nonresected 10% at 3 years, p = 0.17). Conclusions . Response rates and survival are commensurate with multiple completed phase II and III trials. These are attained at a higher treatment-related mortality. T4 patients can be successfully resected in selected patients. Even in advanced disease, nodal status is a significant predictor of survival.

4. Hypermethylation of the GATA gene family in esophageal cancer

Abstract

The GATA family of transcription factors promotes the normal development of the gastrointestinal tract during embryogenesis and determines tissue differentiation in adult gut epithelium. Loss of GATA-4 and GATA-5 has been reported in human gastric and colon cancer. We examined GATA-4,-5 and -6 gene expression in established esophageal squamous cancer cell lines and the relationship to DNA methylation in the promoter region of these genes. GATA-4 and GATA-5 expression was absent in most esophageal cancer cell lines, but was restored upon treatment with the demethylating agent 5-aza-2'-deoxycytidine. For each of the cell lines without detectable GATA gene expression, aberrant methylation of the promoter region CpG-island was detected by methylation specific PCR. We confirmed these results with genomic bisulfite sequencing. GATA-6 expression was found in each of the cell lines. GATA-4/-5 promoter methylation was not detected in normal esophageal mucosa, but GATA-4 methylation was present in 27 of 44 (61%) squamous carcinomas and 31 of 44 (71%) adenocarcinoma of the esophagus, while GATA-5 methylation was present in 14 of 44 (32%) squamous carcinomas and 24 of 44 (55%) adenocarcinoma of the esophagus. Our studies demonstrate frequent silencing of GATA-4 and GATA-5, but not GATA-6, in human esophageal neoplasia associated with gene promoter hypermethylation.

Abstract

Four patients with mild to moderate obstructive sleep apnea were monitored first in the supine posture to establish a diagnosis of obstructive sleep apnea (apnea indices 33, 12, 22, 36). A second polysomnogram, obtained while the patients slept in the lateral posture, showed a dramatic decrease in apnea (apnea indices 5, 0, 0.2, and 0) and snoring. Each patient had an enlarged uvula, which moved to the side in the lateral posture. We conclude that sleeping in the lateral posture may be therapeutic in some patients with obstructive sleep apneas.
