Abstract
Abstract
Background
Systemic amyloidosis is a multi-organ disease characterized by abnormal extracellular protein deposition. The most common type is primary (AL) amyloid relating to underlying plasma cell dyscrasias. Other major variants include secondary (AA) amyloid from chronic inflammation, dialysis related amyloid (DRA) with β2-microglobulin, and heritable protein mutations. Management of the underlying disorder can limit further organ damage; however, no definitive treatment exists for familial causes. While uncommon, gastrointestinal involvement is variable and can cause asymptomatic infiltration, liver impairment, bleeding, or chronic diarrhea.
Aims
To discuss an unusual case of gastrointestinal amyloidosis as a cause of recurrent diarrhea and hypovolemic shock.
Methods
The patient records were examined, and a review of the literature was performed.
Results
An 87-year-old male with dementia, coronary artery disease and end stage renal disease from PCKD presented in hypovolemic shock. He had a two-week history of gradual onset, non-bloody, watery diarrhea with up to 20 bowel movements daily. He denied fever, sick contacts, travel, or recent antibiotic use. He had previously foregone endoscopy for a remote history of self-resolved hematochezia. Examination was notable for an uncomplicated inguinal hernia. Labs showed an anion-gap metabolic acidosis but no leukocytosis. He initially received iv hydration, vasopressors, and empiric antibiotics. CT showed diffuse wall thickening of the terminal ileum, colon and rectum with relative sigmoid sparing concerning for enterocolitis. Stool culture grew C. albicans, but C. difficile toxin and Ova and Parasite PCR were negative. He clinically improved with loperamide and was discharged only to be readmitted four days later with recurrent diarrhea and hypovolemia. Repeat cultures were negative. Endoscopy showed diffuse well-demarcated clean-based ulcers and colonic edema. Biopsies excluded viral causes but showed a classic appearance of apple-green birefringence on Congo red staining suggesting amyloid deposition. Raised light chain immunoglobulins and lysozyme on proteomic analysis indicated either AL or a heritable amyloid but excluded AA and DRA. Full diagnostic criteria for AL were not met as free light chain ratio was preserved without clear monoclonality. While his diarrhea again improved, next-of-kin opted for palliative care due to repeated admissions for delirium and generalized deterioration.
Conclusions
This case was indicative of atypical AL amyloidosis versus a rare lysozyme mutation involving renal and GI systems. AL amyloid has a classic appearance on special stains and mass spectrometry that distinguishes it from most subtypes, however, given elevated lysozyme levels further genetic analysis is needed to guide management. In the appropriate clinical context, gastrointestinal amyloidosis can be considered as a rare cause of recurrent unexplained diarrhea.

Abstract
BACKGROUND The palliation of dysphagia in metastatic esophageal cancer remains a challenge, and the optimal approach for this difficult clinical scenario is not clear. We therefore sought to define and determine the efficacy of various treatment options used at our institution for this condition. METHODS We reviewed a prospective database for all patients managed in an esophageal cancer referral centre over a 5-year period. All patients receiving palliation of malignant dysphagia were reviewed for demographics, palliative treatment modalities, complications, and dysphagia scores (0 = none to 4 = complete). The Wilcoxon signed rank test was used to determine significance (p < 0.05). RESULTS During 2004-2009, 63 patients with inoperable esophageal cancer were treated for palliation of dysphagia. The primary treatment was radiotherapy in 79% (brachytherapy in 18 of 50; external-beam in 10 of 50; both types in 22 of 50), and stenting in 21%. Mean wait time from diagnosis to treatment was 22 days in the stent group and 54 days in the radiotherapy group (p = 0.003). Mean duration of treatment was 1 day in the stent group and 40 days in the radiotherapy group (p = 0.001). In patients treated initially by stenting, dysphagia improved within 2 weeks of treatment in 85% of patients (dysphagia score of 0 or 1). However, 20% of patients presented with recurrence of dysphagia at 10 weeks of treatment. In the radiotherapy group, the onset of palliation was slower, with only 50% of patients palliated at 2 weeks (dysphagia score of 0 or 1). However, long-term palliation was more satisfactory, with 90% of patients remaining palliated after 10 weeks of treatment. CONCLUSIONS In inoperable esophageal cancer at our centre, radiation treatment provided durable long-term relief, but came at a high price of a long wait time for initiation of treatment and a long lag time between initiation of treatment and relief of symptoms. On the other hand, endoluminal stenting provided more rapid and effective early relief from symptoms, but was affected by recurrence of dysphagia in the long-term. It is now time for a prospective randomized trial to assess the safety and efficacy of combined-modality treatment with both endoluminal stenting and radiation therapy compared with either treatment alone.

Abstract
Eosinophilic esophagitis (EoE) is now recognized as a common cause of dysphagia. Eosinophilic infiltration of the esophagus has also been associated with other conditions, such as gastroesophageal reflux disease (GERD); however, the incidence, pattern, and clinical significance of eosinophilic infiltration in achalasia are poorly documented. We sought to characterize this histological finding in patients undergoing Heller myotomy (HM) for achalasia. Ninety-six patients undergoing laparoscopic HM for primary achalasia between 1999 and 2008 were identified from a prospective database. Serial mid and distal per-endoscopic esophageal biopsies taken from patients before and after surgery were assessed for the presence of elevated intraepithelial eosinophils (EIEs). Slides from patients with reports suggestive of EIE were reviewed independently by two pathologists, and the highest eosinophil count/high-power field (eos/hpf) was recorded. Dysphagia scores (0 = none to 5 = severe dysphagia), GERD health-related quality of life scores (0 = best to 45 = worst), and 24-hour pH results were compared before and 3 months after surgery. We related the highest eos to the symptoms and response to HM. Data are presented as median (range). Paired t-test and Wilcoxon signed-rank test determined significance, *P < 0.05. Of 96 patients with achalasia, 50 had undergone pre-HM biopsies revealing EIE in 17/50 (34%), with a median of 3 eos/hpf (1-21). Two patients were found to have superimposed esophageal candidiasis. One patient met the pathologic criteria for EoE. Twenty-five of 50 (50%) postoperative biopsies demonstrated a median of 5 eos/hpf (1-62) for a total of 28/50 patients (56%) with EIE in either the preoperative or postoperative period. Four patients (8%) met the pathologic criteria for EoE, and two demonstrated persistent esophageal candidiasis. A decrease in eosinophils was found in 6/28 patients (21%) from 3/hpf (1-21) to 0.5/hpf (0-4). Increase in eosinophils was found in 22/28 patients (79%) from 0.5/hpf (0-8) to 5/hpf (1-62). Preoperative and postoperative dysphagia scores were available in 23 patients. Dysphagia scores improved in 22/23 patients. (3 [0-5] to 0 [0-2])*. Preoperative and postoperative GERD scores were available in 21 patients. GERD scores improved in 20/21 patients (10 [3-38] to 2 [2-14])*. Four of 13 patients (30.7%) demonstrated significant reflux in the postoperative period. No difference in clinical response to HM was detected between patients with preoperative EIE compared with patients with no EIE. No correlation between postoperative esophageal pH and eos was observed. A significant number of patients with achalasia demonstrate esophageal eosinophilic infiltration even at numbers demonstrable in patients with EoE (8% 4/50). While the interaction between achalasia and esophageal eosinophilic infiltration needs further investigation, this does not represent a distinct clinical entity. Thus, the presence of esophageal eosinophils in patients presenting with dysphagia should not preclude further work-up for other etiologies, including achalasia.

Abstract
Limited access to esophageal manometry (EM) may delay identification and treatment of patients with achalasia. In order to assess predictors to fast-track patients for manometric confirmation of achalasia, we compared the clinical, radiographic, and endoscopic characteristics of achalasia patients to patients with functional dysphagia without manometric features of achalasia (controls). Patients referred for esophageal manometry to assess functional dysphagia prospectively identified over a 12-month period were asked to participate in this study. The Achalasia Symptom Questionnaire (ASQ), a structured 11-question survey (score: 0-best, 67-worst), was completed by all consenting patients. ASQ scores, esophago-gastro-duodenoscopy and upper gastro-intestinal (UGI) contrast study findings were compared between patents with subsequently confirmed achalasia and those in whom achalasia was excluded by EM. Univariate logistic regression identified predictors that were tested by multivariate logistic regression to generate the model. Of the 803 EM performed over this 12-month period, 95 patients were referred specifically to assess functional dysphagia. Of these, 50 were confirmed to have achalasia, and 45 had dysphagia without manometric evidence for achalasia and hence comprised the control group. ASQ scores were higher in achalasia patients (37+/-13 versus 23+/-10). Endoscopy and/or contrast esophagogram reports were available in 92% achalasia patients and 80% controls. Significant predictors for achalasia identified on univariate logistic regression included ASQ score, abnormal findings on endoscopy, and contrast UGI study. Using multivariate logistic regression, we were able to accurately predict the probability of achalasia to be P where P=ey/(1+ey) and y=5.6+(0.089xASQ)+(2.088xEGD)+(3.083xUGI), e=exponential constant 2.7182, esophagogastroduodenoscopy (EGD) and UGI=0 if normal and 1 if abnormal. Dropping the predictor ASQ, the formula changes to y=-2.7+(1.987xEGD)+(2.861xUGI). Using only noninvasive investigations (i.e. eliminating EGD), the formula changes to y=-4.9653+(0.0951xASQ)+(3.4312xUGI). The probability of achalasia can be calculated in patients with functional dysphagia based on clinical, endoscopic, and radiographic findings allowing for a prioritization of EM studies.

Abstract
BACKGROUND The purpose of this study is to assess how subjective evaluation (heartburn, dysphagia, quality of life, and satisfaction) correlates with objective data after Heller myotomy and Dor fundoplication for achalasia. METHODS A total of 53 consecutive patients with achalasia undergoing laparoscopic Heller myotomy and Dor fundoplication were studied prospectively. Subjective evaluation was done preop and postop using the Gastroesophageal Reflux Disease Health-Related Quality of Life instrument (GERD-HRQL; 0 = best, 45 = worse), 4-point dysphagia and heartburn scales (0 = best, 3 = worst), patient satisfaction scale (0 = very satisfied, 5 = incapacitated), and the SF-12 general health-related quality-of-life score. At 3 months postop, patients were asked to undergo objective evaluation with 24-h pH testing, manometry, and endoscopy. Data are expressed as median (interquartile range) and analyzed by Wilcoxon signed rank test or Mann-Whitney U test. RESULTS Forty-nine patients were more than 3 months postsurgery. Comparing preop to postop, improvements were found in dysphagia [3 (2-3) to 0 (0-1)], heartburn [1 (0-2) to 0 (0-1)], GERD-HRQL [13.5 (6.3-22.5) to 2 (0-5)], satisfaction [3 (3-4) to 1 (0-1)], and SF-12 mental component summary [46 (37-56) to 58 (50-59)] and physical component summary [46 (36-53) to 55 (48-56)] scores (p < 0.0001 for all). Thirty-eight patients (78%) agreed to undergo objective testing, and complete data were available for 32 (65%). Four of 32 patients (12.5%) had evidence of reflux based on 24-h pH testing. Of nine patients with GERD-HRQL >5, only two had positive pH test (22%). Of 23 patients with GERD-HRQL <5, two had positive pH test (7%). Of four tested patients with moderate to severe heartburn, two had an abnormal pH test. There was no significant relationship between GERD-HRQL score and pH test results. Lower esophageal sphincter pressure (LESP) decreased from 24 (16-35) to 13 mmHg (11-17) (p < 0.001). There was no relationship between dysphagia score and postop absolute LESP or a decrease in LESP after operation. CONCLUSIONS Laparoscopic Heller myotomy and Dor fundoplication is an effective treatment for achalasia. Subjective evaluation can document patient satisfaction and health-related quality of life but does not accurately reflect postop reflux. Twenty-four-hour pH study is required to accurately assess reflux disease.

Abstract
BACKGROUND The most appropriate approach to the repair of large paraesophageal hernias remains controversial. Despite early results of excellent outcomes after laparoscopic repair, recent reports of high recurrence require that this approach be reevaluated. METHODS For this study, 60 primary paraesophageal hernias consecutively repaired at one institution from 1990 to 2002 were reviewed. These 25 open transabdominal and 35 laparoscopic repairs were compared for operative, short-, and long-term outcomes on the basis of quality-of -life questionnaires and radiographs. RESULTS No difference in patient characteristics was detected. Laparoscopic repair resulted in lower blood loss, fewer intraoperative complications, and a shorter length of hospital stay. No difference in general or disease-specific quality-of-life was documented. Radiographic follow-up was available for 78% open and 91% laparoscopic repairs, showing anatomic recurrence rates of 44% and 23%, respectively (p = 0.11). CONCLUSIONS Laparoscopic repair should remain in the forefront for the management of paraesophageal hernias. However, there is considerable room for improvement in reducing the incidence of recurrence.

Abstract
BACKGROUND The role of Helicobacter pylori in gastro-oesophageal reflux disease (GERD) is controversial. AIM To compare the severity of GERD in infected vs. non-infected patients, as part of an ongoing randomized controlled trial that examines the impact of H. pylori eradication on GERD-related outcomes. METHODS Consecutive GERD patients underwent urea breath testing and completed validated GERD symptom severity, and quality of life questionnaires as well as, 24-h pH-metry. These parameters, as well as demographics and endoscopic findings were assessed in double-blinded fashion and compared between H. pylori-infected and non-infected subjects. RESULTS Helicobacter pylori-infected GERD patients (n=50) were significantly older and less educated than non-infected patients (n=51). They also used proton pump inhibitors less often but had no difference in symptoms (as measured with both the Spechler's Activity Index and the Gastrointestinal Symptom Rating Scale), quality of life, endoscopic findings or 24-h pH-metry findings. CONCLUSION This prospective, double-blind study demonstrates, using excellent GERD quantifying measures including validated symptom severity scores, endoscopy, and 24-h pH-metry, that there exist no clinically significant differences in clinical or laboratory-related GERD manifestations between H. pylori-infected and non-infected GERD patients.

Abstract
The prevalence of H. pylori infection and PUD seem not to be different in CRF patients as compared with the general population. However, PUD in CRF patients seems to have some unique features-namely, lack of pain and higher associations with bleeding, with post-bulbar location, and with multiple ulcers. No increase in GERD has been proven in adults, but several studies demonstrate increased GERD in pediatric CRF patients. The causes of the increase in GERD may include delayed gastric emptying owing to altered myoelectric activity, or perhaps to an increased production of gastric acid, but evidence for the latter is small. Importantly, treating the problem may lead to better nutrition and higher albumin levels, thus improving patient prognosis.

Abstract
BACKGROUND Surgical success has traditionally been judged from the surgeon's perspective. A more complete evaluation of outcome incorporates the patient's, surgeon's, and payor's perspectives. Because gastroesophageal reflux disease (GERD) is primarily a quality-of-life (QOL) problem, the evaluation of laparoscopic fundoplication (LF) is a useful model for evaluating outcomes from these 3 perspectives. METHODS Between 1995 and 2000, 74 patients underwent primary LF for GERD. In addition to undergoing physiologic testing, 63 patients (85%) were evaluated with use of a disease-specific health-related QOL scale (GERD-HRQL), scored from 0 (no symptoms) to 45 (incapacitating symptoms). Thirty-three patients also completed a generic QOL questionnaire (SF-12), in which patient satisfaction was scored from 1 (very satisfied) to 5 (very dissatisfied). Preoperative and postoperative data were compared with use of the Wilcoxon signed rank test or the paired t test. RESULTS The median GERD-HRQL score improved from 18 to 0 at 2 years postoperation (P <.01). The median satisfaction score improved from 5 to 1 (P <.01). The SF-12 summary scores also improved after 6 weeks postoperatively (P <.05). The mean +/- SD lower esophageal sphincter pressure rose from 7.3 +/- 4 mm Hg preoperatively to 17.5 +/- 6 postoperatively (P <.01), and the mean percentage of time that the esophagus was exposed to a pH of less than 4 declined from 14.7% +/- 12% to 1.1% +/- 2% (P <.01). The median operative time was 110 minutes, which declined with experience with the procedure (P <.01). Median postoperative stay was 2 days. CONCLUSIONS In evaluating the outcomes of a new procedure, 3 overlapping points of view were addressed: the patient's (QOL, satisfaction), the surgeon's (physiologic changes), and the payor's (operating room time, hospital stay). With use of this framework, we found that LF for GERD improves QOL, corrects the physiologic abnormalities, and is associated with short hospitalization and operating time that declines with experience with the procedure.

Abstract
OBJECTIVES A recent report has suggested an association between Helicobacter pylori eradication and the development of gastroesophageal reflux disease (GERD). We therefore assessed the incidence of GERD among comparable patients having undergone successful versus failed H. pylori eradication in a controlled trial. We also compared the H. pylori strains in the subjects that developed GERD to those that did not. METHODS Patients with a history of proven duodenal ulcer and H. pylori infection were randomised into a H. pylori eradication study. Patients subsequently underwent gastroscopy with gastric biopsies every 3 months for 1 yr. At each visit, the presence of GERD symptoms and endoscopic esophagitis were noted, and the incidence of these variables among patients in whom H. pylori eradication was successful was compared to those in whom it was not. In a subgroup, the presence of the cagA, cagE, and vacA genotypes and of cagA antibodies were determined. RESULTS Of 98 patients randomized into this study, 11 dropped out before determination of H. pylori eradication, leaving 87 patients with analyzable results. H. pylori eradication was successful in 63 (72%). By the end of the follow-up period, patients with GERD symptoms or endoscopic esophagitis were more prevalent in the successful than in the failed eradication group (37% [95% CI: 25-50%] vs 13% [95% CI: 3-32%], p = 0.04, 95% CI for the difference: 6-42%), as were patients with GERD symptoms alone (29% [95% CI: 18-41%] vs 8% [95% CI: 1-27%], p = 0.04, 95% CI for the difference: 4-36%) or esophagitis alone (21% [95% CI: 12-33%] vs 4% [95% CI: 0-21%], p = 0.10, 95% CI for the difference: 4-29%, respectively). Multivariate analysis revealed no significant association between the incidence of symptoms or esophagitis and age, gender, Quetelet index, caffeine or alcohol intake, smoking, weight change, or the presence of a hiatus hernia. There were also no differences in the prevalence of H. pylori genotypes from patients who developed GERD as compared to those who did not. CONCLUSIONS In this patient population, the incidence of new GERD-type symptoms or endoscopic esophagitis was greater in patients in whom successful eradication was achieved. This difference does not appear to be attributable to weight gain, habits, or specific H. pylori strains.

Abstract
Symptomatic stricturing of the esophagus complicates the course of about 10% to 15% of patients with gastroesophageal reflux disease, particularly if they are elderly or if there is an associated Barrett's esophagus. Treatment goals include relief of symptoms of reflux disease and dysphagia, and prevention of their recurrence. The main therapeutic option to date has been endoscopic dilation. Although more than 30% of patients require serial long term dilations, this proportion can be minimized by the concomitant use of long term, high dose proton pump inhibition. Indications for surgery include failure of medical management. It is too early to assess the impact of laparoscopic technology on the treatment of peptic strictures. At this time, well designed prospective comparative trials are needed to quantify better the cost effectiveness of available treatment strategies in the management of patients with esophageal peptic strictures.

Abstract
Barrett's esophagus represents the most serious consequence of chronic gastroesophageal reflux disease (GERD), primarily because of its association with an increased incidence of esophageal adenocarcinoma. Specific therapy for Barrett's esophagus should lead to the complete regression of the metaplastic epithelium with adequate squamous reepithelialization. Ideally, this regression should be permanent and be associated with a reduction in the incidence of adenocarcinoma. Several reports in the literature have assessed the effects of H2-blocker treatment of Barrett's epithelium, but none has clearly documented a significant and consistent regression of the metaplastic epithelium. Proton pump inhibitors have been shown to be superior to H2 blockers in the treatment of patients with severe esophagitis. Despite initial enthusiasm, it does not appear that a significant regression of Barrett's epithelium can be achieved, even with high doses of proton pump inhibitors given for a prolonged period of time. Various groups have assessed the effects of antireflux surgery on the regression of columnar epithelium and dysplasia and its potential protective effect on the subsequent development of carcinoma. Overall, it appears from these reports that antireflux surgery, despite adequate symptomatic results, does not significantly and consistently lead to a reduction in length or disappearance of the Barrett's mucosa, and does not prevent the development of dysplasia and its progression to carcinoma. More recently, numerous authors have documented the regression of Barrett's mucosa by using various endoscopic thermal modalities. Technological advances including laser and photodynamic therapy have allowed for endoscopic mucosal ablation. Long term results are more encouraging when this mucosal ablation is associated with aggressive antireflux therapy (medical or surgical). Further studies are required before these exciting new therapies can be recommended. Currently, none of these approaches can obviate the need for continued endoscopic surveillance.

Abstract
Pneumatosis cystoides intestinalis (PCI) is a condition characterized by the presence of gas-filled cysts in the submucosa or subserosa of the gastrointestinal tract. PCI has been described by various radiographic methods but its laparoscopic features have not been previously described. We report a case of a 77-yr-old male with marked ascites and radiographic evidence of pneumatosis cystoides intestinalis of the ileum who underwent a laparoscopy to determine the cause of his ascites. The characteristic laparoscopic features of PCI are described, and its radiographic features are reviewed.

Abstract
PURPOSE Toxic megacolon is a rare complication of pseudomembranous enterocolitis. We reviewed our recent experience with this complication. METHODS The first five patients of the series were studied retrospectively, and six others were followed prospectively. RESULTS Between June 1992 and May 1994, 11 patients (8 male, 3 female) developed toxic megacolon secondary to pseudomembranous enterocolitis. Mean age was 60.7 +/- 11.8 (range, 40-79) years. Presenting symptoms and signs included diarrhea, 100 percent; malaise, 91 percent; abdominal pain, 82 percent; abdominal distention, 82 percent; abdominal tenderness, 72 percent; anemia less than 12 gm, 72 percent; albumin less than 3 gm, 64 percent; tachycardia greater than 100, 55 percent; fever greater than 38.5 degrees celsius, 45 percent; shock or hypotension, 45 percent. Predisposing factors included antibiotics, 64 percent; immunosuppressants or chemotherapy, 36 percent; antidiarrheals, 27 percent; and barium enema in one patient. Five patients (45 percent) had more than one predisposing factor. X-rays showed transverse colon dilation and loss of haustrations in eight patients (72 percent), with a mean diameter of 9.9 +/- 3.4 cm. Flexible proctosigmoidoscopy showed pseudomembranes in all scoped patients, and toxin assay for Clostridium difficile was positive in all patients. One patient had emergency surgery. Ten patients were initially treated medically with nasogastric suction and intravenous resuscitation (90 percent) and antibiotics (100 percent), usually in the intensive care unit (80 percent). Four patients did not respond and underwent surgery; two others improved, then deteriorated, and also underwent surgery. Altogether, 7 of 11 patients (64 percent) underwent surgery. Three patients (27 percent) responded well to medical treatment. One patient was deemed too ill to undergo surgery and died. Mean delay to surgery was 3.0 +/- 1.3 days. No sealed or overt perforation was found at laparotomy. All patients who underwent surgery had a subtotal colectomy, with either a Hartmann's stump (71 percent) or a mucous fistula (29 percent). Eventually, five of seven patients who were operated on and two of four medically treated patients died (overall mortality, 64 percent). Only one patient underwent closure of ileostomy and anastomosis. CONCLUSION Toxic megacolon complicating pseudomembranous enterocolitis is a serious problem that carries a high morbidity and mortality rate, regardless of treatment.

Abstract
Using an isotonic recording device (barostat), we assessed feline esophageal smooth and striated muscle tone in vivo and determined the effects of a cholinergic agonist (bethanechol) and antagonist (atropine) and the effect of body position on this tone. Studies were performed on six cats under light intravenous ketamine anesthesia. Two parameters were analyzed: compliance and resistance to initial stretch (resting tone). Smooth muscle compliance (0.51 +/- 0.03 ml/mmHg) was significantly greater than that of the striated muscle section (0.26 +/- 0.02 ml/mmHg; P = 0.0260). Resting tone was low in both esophageal sections. Neither atropine nor bethanechol had any significant effect on the two tone parameters measured in smooth muscle. Change in body position had no influence on the intraesophageal balloon volume. We conclude that esophageal wall compliance varies according to location (smooth vs. striated muscle) and that esophageal smooth muscle tone is not under cholinergic excitatory control. Isotonic recording in vivo should allow further investigations of the nature of the neural and myogenic control of esophageal tone and of the relationships between phasic and tonic activity.

Abstract
BACKGROUND Conventional perfused manometry has led to extensive study of phasic contractile activity in the human esophagus, but little is known about esophageal tonic activity. The aims of this study were to assess esophageal smooth and striated muscle tone and the effect of a smooth muscle relaxant (amyl nitrite, 0.3 mL inhalation) on this tone. METHODS Using a computerized isobaric recording system (barostat), esophageal tonic activity in 13 healthy subjects was recorded. Two parameters were analyzed: compliance and resistance to initial stretch (resting tone). RESULTS The smooth muscle esophagus was significantly more compliant but presented a greater resistance to initial stretch than the striated muscle section. Amyl nitrite affected only the smooth muscle section, significantly increasing compliance and decreasing the resistance to initial stretch. Significant chest pain and/or discomfort occurred only during striated muscle esophagus distension (10 of the 13 subjects at 25 mm Hg distending pressure). CONCLUSIONS Active tone is present in the smooth muscle esophagus and can be modulated by a smooth muscle relaxant. Compliance and resting tone differ between the smooth and striated muscle segments of the esophagus. Assessment of tone in patients with esophageal motor disorders and noncardiac chest pain should provide further insights into these disorders.

Abstract
The coordination of swallowing and respiration, as measured by nasal airflow, and the effect of changes in the volume of the swallow bolus (0-20 ml) were investigated in 12 normal subjects. Both nonbolus and bolus swallows were usually preceded and followed by expiratory airflow. Swallows followed by inspiratory airflow accounted for 20% of nonbolus swallows but decreased further in frequency in the presence of a bolus. Swallowing was associated with an apneic period lasting 1.90 +/- 0.26 s for nonbolus swallows. Based on the apneic period response to bolus volume, the subjects were divided into two groups. The apneic period decreased by 60% in seven of the subjects regardless of bolus volume. The remaining five subjects gradually increased swallow apnea as bolus volume was increased. At larger bolus volumes, the latter group also exhibited an earlier onset of the swallow apnea and an increase in the number of swallows preceded by inspiration. The duration of the swallow-associated respiratory cycle was similarly prolonged by an increase in bolus volume in both groups. The results indicate that the respiratory pattern associated with swallowing is modulated by the volume of the swallow bolus. Within the normal population, at least two different patterns of response to bolus volume are identified.

Abstract
Heterogeneous nuclear RNA is normally complexed with a specific set of proteins, forming ribonucleoprotein particles termed hnRNP. These particles are likely to be involved in mRNA processing. We have found that the structure of hnRNP is profoundly altered during the heat shock response in Drosophila cultured cells. Although hnRNA continues to be synthesized at a near-normal rate during heat shock, its assembly into hnRNP is incomplete, as evidenced by a greatly decreased protein content of the particles in Cs2SO4 density gradients. RNA-protein cross-linking conducted in vivo (Mayrand and Pederson, Proc. Natl. Acad. Sci. U.S.A. 78:2208-2212, 1981) also reveals that hnRNA made during heat shock is complexed with greatly reduced amounts of protein. The block of hnRNP assembly occurs immediately upon heat shock, even before the onset of heat shock protein synthesis. Additional experiments reveal that hnRNP assembled normally at 25 degrees C subsequently disassembles during heat shock. The capacity for normal hnRNP assembly is gradually restored after heat-shocked cells are returned to 25 degrees C. Heat-shocked mammalian cells also show a similar block in hnRNP assembly. We suggest that incomplete assembly of hnRNP during heat shock leads to abortive processing of most mRNA precursors and favors the processing or export (or both) of others whose pathway of nuclear maturation is less dependent on, or even independent of, normal hnRNP particle structure. This hypothesis is compatible with a large number of previous observations.

Abstract
The processing of heterogeneous nuclear RNA into messenger RNA takes place in special nuclear ribonucleoprotein particles known as hnRNP. We report here the identification of proteins tightly complexed with poly(A)+ hnRNA in intact HeLa cells, as revealed by a novel in situ RNA-protein cross-linking technique. The set of cross-linked proteins includes the A, B, and C "core" hnRNP proteins, as well as the greater than 42,000 mol wt species previously identified in noncross-linked hnRNP. These proteins are shown to be cross-linked by virtue of remaining bound to the poly(A)+ hnRNA in the presence of 0.5% sodium dodecyl sulfate, 0.5 M NaCl, and 60% formamide, during subsequent oligo(dT)-cellulose chromatography, and in isopycnic banding in Cs2SO4 density gradients. These results establish that poly(A)+ hnRNA is in direct contact with a moderately complex set of nuclear proteins in vivo. This not only eliminates earlier models of hnRNP structure that were based upon the concept of a single protein component but also suggests that these proteins actively participate in modulating hnRNA structure and processing in the cell.

Abstract
Contacts between heterogeneous nuclear RNA (hnRNA) and protein in nuclear ribonucleoprotein particles have been photochemically crosslinked in intact HeLa or Friend erythroleukemia cell by irradiation with 254-nm light at doses of 10(1) to 10(5) ergs/mm2 (1 to 10(4) microJ/mm2). The resulting crosslinked particles were isolated and compared with conventional hnRNA . protein (hnRNP) preparations. By the criteria of nuclear fractionation behavior, sedimentation coefficients, nuclease digestion profiles, and RNA-to-protein ratio measured by banding in Cs2SO4 density gradients, the hnRNP particles crosslinked in vivo are identical to nonirradiated particles. Gel blot hybridization of RNA from Friend cell hnRNP crosslinked in vivo reveals that beta-globin RNA sequences remain both intact and hybridizable after the irradiation procedure. The crosslinked hnRNA--protein bonds are stable in 8 M urea/0.5% sodium dodecyl sulfate and withstand centrifugation in Cs2SO4 gradients of initial density 1.50 g/cm3. These results establish that hnRNA is tightly complexed with nuclear proteins in vivo and that hnRNP particles isolated by nuclear fractionation represent native structures.
