We describe the clinical and pathologic features of a hitherto unreported finding in patients with esophagitis: the presence of multinucleated squamous epithelial giant cells simulating viral cytopathic effect and/or dysplasia. Routinely processed hematoxylin and eosin (H&E)-stained slides of esophageal mucosal biopsies from 14 patients with both active esophagitis and multinucleated epithelial giant cells were evaluated for a variety of inflammatory and epithelial features. Clinical, endoscopic, and follow-up data were collected and correlated with the histologic findings. Immunostaining (ABC method) for cytokeratin AE1/AE3, S-100, MIB-1, herpes simplex virus 1 and 2 (HSV), cytomegalovirus (CMV), as well as DNA in situ hybridization for human papilloma virus (HPV-ISH) was performed in all cases. Electron microscopic evaluation for viral particles was performed in three cases. The study group consisted of nine men and five women (mean age 59 years; range 23-87 years; 12 white, one black, one Hispanic). Patients presented with dysphagia or odynophagia (n = 5), upper gastrointestinal bleeding (n = 5), heartburn (n = 2), or abdominal pain (n = 2). The etiology of esophagitis was attributed to gastroesophageal reflux in 10, radiotherapy in one, Candida infection in one, drug-induced (alendronate) in one, and unknown in 1. Endoscopically, seven patients had an ulcer or erosion, four erythema, two stricture formation, and one white mucosal plaques. Microscopically, all cases showed multiple multinucleated (mean three nuclei per cell, range two to nine) squamous epithelial cells (range 2 to 11 cells per biopsy) confined to the basal zone in nine of 14 cases and involving the basal and superficial epithelium in the remainder. The nuclei contained a single or multiple eosinophilic nucleoli with a perinucleolar halo, but no inclusions, hyperchromaticity, or atypical mitoses. All cases showed associated nonspecific features of active esophagitis such as ulceration, neutrophilic and eosinophilic inflammation, basal cell hyperplasia, and elongation of the lamina propria papillae. The multinucleated giant cells, in all cases, were strongly positive for cytokeratin AE1/AE3 and were negative for S-100, HSV I and II, CMV, and HPV-ISH. MIB-1 positivity was observed in all basally located multinucleated giant cells, whereas those in the more superficial layers were negative. Electron microscopy failed to show viral particles in three of three cases. After treatment, all patients demonstrated clinical improvement. Three patients in whom follow-up biopsies were performed showed no evidence of esophagitis, epithelial cell multinucleation, or dysplasia. Multinucleated epithelial giant cell changes may rarely be seen in patients with esophagitis of varying etiology and probably represent a regenerative response to injury. This feature is important to distinguish from either viral cytopathic effect or dysplasia.

A case with esophageal anisakiasis accompanied by reflux esophagitis is described. A 38-year-old man visited our hospital with complaints of heartburn and disturbance of food passage about seven hours after eating raw cuttlefish. The first esophagogastroscopy revealed an anisakis larva invading the squamocolumnar junction. Near the anisakis larva, a whitish exudate was demonstrated in the distal esophagus just proximal to the squamocolumnar junction. An anisakis larva was easily extracted from the esophagus by forceps. Reflux esophagitis with whitish exudative mucosal lesions and an area of linear erythema more than 5mm long were noted endoscopically 8 weeks after treatment with lansoprazole and cisapride. After six months the third endoscopic examination clarified that there was neither exudate nor erythema in the distal esophagus. Judging from the clinical course that he complained of newly experienced heartburn about seven hours after eating raw cuttlefish, and that whitish exudative mucosal lesions and an area of linear erythema did not disappear at three months after extraction of the anisakis larva. It was concluded that an anisakis larva enters the stomach first and then returns to the esophagus by gastroesophageal reflux.

In otorhinolaryngology, the relationship between gastroesophageal reflux (GER) and pharyngolaryngeal disorders is well-known. In fact, many patients with GER debut with head and neck symptoms or are first seen by an otolaryngologist. We proposed to identify the ENT symptoms most frequently associated with GER, to differentiate between physiological and pathological GER, and to confirm the effectiveness of antacid treatment. Our study included 20 ambulatory patients who presented pharygolaryngeal symptoms and clinical manifestations of GER (heartburn and regurgitation). The patients underwent a complete ENT examination and were referred to a gastroenterologist for esophagoscopy, manometry, and 24-hour pH monitoring. All patients received antireflux therapy for one month (ranitidine 150 mg given twice daily). We conclude that GER produces a variety of manifestations, but the most frequent pharyngolaryngeal symptoms and physical findings were globus pharyngeus and erythema of the arytenoids, respectively. Pathological GER was found in only one third of our patients and 90% responded well to treatment.

Gastroesophageal reflux disease (GERD) is the most common esophageal disease. Besides the typical presentation of heartburn and acid regurgitation, either alone or in combination, GERD can cause atypical symptoms. An estimated 20 to 60 percent of patients with GERD have head and neck symptoms without any appreciable heartburn. While the most common head and neck symptom is a globus sensation (a lump in the throat), the head and neck manifestations can be diverse and may be misleading in the initial work-up. Thus, a high index of suspicion is required. Laryngoscopy can confirm the diagnosis of laryngopharyngeal reflux. Erythema of the posterior larynx may be seen, and the true vocal cords may be edematous. Treatment should be initiated with a histamine H2 receptor blocker or proton pump inhibitor. Lifestyle changes are also beneficial. Untreated, GERD can lead to chronic laryngitis, dysphonia, chronic sore throat, chronic cough, constant throat clearing, granuloma of the true vocal cords and other problems.

Acute febrile neutrophilic dermatosis or Sweet's syndrome is a well-described acute condition with possible paraneoplastic and inflammatory associations. A case of a 49-year-old man with a prior history of Hodgkin's disease is described, who underwent a laparotomy for operative treatment of a small intestinal stricture and therapy-refractory gastroesophageal reflux. Incidentally, mild mesenteric lymphadenopathy was encountered, and a biopsy confirmed the presence of a new, unrelated low-grade follicular lymphoma. Two weeks postoperatively, the patient developed a tender erythematous plaque at the site of the Bovie electrocautery pad on the proximal thigh. Over the following week, the affected area extended in size, and became markedly edematous and infiltrated, with hemorrhagic surface studding. Multiple small plaques, some with annular arrays of pustules, were found on the opposite lower extremity, the lower back, and the arms. A skin biopsy suggested the presence of Sweet's syndrome, and corticosteroid treatment was initiated. All cutaneous manifestations disappeared within 48 h except for the presence of postinflammatory erythema. Acute neutrophilic dermatoses have not been previously described in this postoperative presentation. The differential diagnostic importance of this emergent entity and the potential for it being caused by surgical trauma are discussed.

Recently, gastroesophageal reflux (GER) has been found to contribute to many types of otolaryngologic pathology in infants and children. The complaints may be intermittent and unresponsive to usual therapies, such as antimicrobial treatments. A high index of suspicion for GER and for the concept of "silent" GER (GER without overt symptoms) is necessary for accurate diagnosis and treatment of otolaryngologic manifestations of GER in these patients. In this prospective historical cohort study, the records were reviewed from 101 children who underwent esophagoscopy and biopsy as a diagnostic test for GER at the time of other otolaryngologic procedures. Significant associations were found between the presence of histologic esophagitis and asthma, recurrent croup, cough, apnea, sinusitis, stridor, laryngomalacia, subglottic stenosis, posterior glottic erythema, and posterior glottic edema. There were no complications. Esophageal biopsy is a rapid, safe and effective diagnostic test for GER that should be considered at the time of other procedures in children with selected GER-associated problems.

Endoscopy is, currently, the initial investigation of choice for the investigation of gastroesophageal reflux disease (GERD) in clinical practice and clinical research. Erosion severity is predictive of a patient's response to therapy and of the likelihood of relapse after therapy. It is, therefore, important to grade the severity of erosive reflux esophagitis, particularly in the context of clinical trials. The Savary-Miller endoscopic classification system is used widely but usage and interpretation are very variable. The "MUSE" (metaplasia [M], ulceration [U], stricturing [S] and erosions [E]) classification provides clear definitions of the relevant endoscopic features, and it is based on a standardized report form, which allows the endoscopist to make a clear record of esophagitis severity. Recent studies confirm that endoscopists can identify erosions or mucosal breaks, ulcers, strictures, and metaplasia reproducibly. The "L.A." (Los Angeles) classification describes four grades of esophagitis severity (A to D), based on the extent of esophageal lesions known as "mucosal breaks," but it does not record the presence or severity of other GERD lesions. Thus, for patients with "complicated" reflux disease, the "MUSE" classification offers a more comprehensive description of esophagitis severity. Endoscopy is not universally applicable: 40 to 60 percent of patients with typical reflux symptoms do not have esophageal erosions and are now considered to have "endoscopy negative reflux disease" (ENRD). Thus, endoscopy is not the final arbiter as to a diagnosis of reflux disease, and it is not, therefore, a necessary prerequisite to therapy. Endoscopy is indicated at first presentation for patients with alarm symptoms referable to the upper gastrointestinal tract. It has also been proposed that all patients with chronic GERD should have a "once-in-a-lifetime" endoscopy; in the absence of Barrett's esophagus or other complications, no follow-up is required unless the patient's symptoms change significantly. A surveillance program with multiple biopsies should be instituted if there is evidence of Barrett's esophagus. Endoscopic evaluation should document the presence and extent of esophageal erosions using the L.A. or MUSE classification systems; complications should also be documented and may be recorded using the MUSE classification. Non-erosive changes such as erythema may be ignored on the basis of present evidence, and there are no clear data to support the use of endoscopic biopsies for the diagnosis of GERD.

The purpose of our study was to assess gastroesophageal reflux (GER) by dual-probe pH monitoring in children suffering from chronic hoarseness for more than six months. Seventeen children (aged between 2 and 12 years, 10 boys and 7 girls) were enrolled. All children underwent a laryngoscopy and a 24-hour dual-probe pH monitoring. At both sensor, distal and proximal esophageal, a pathological GER was defined as the presence of episodes of acid reflux with pH < 4 during a fraction of the total recording time greater than 5.2 percent. The computer considered the child was supine when asleep and upright when awake. Laryngoscopy revealed interarytenoid erythema and/or edema with vocal cord nodules or granulomas in 13 cases (76.4%), isolated vocal nodules or granulomas in three cases (17.6%) and a normal appearance in one case (5.8%). At both sensors, the majority of refluxes occurred when the child was upright, as analyzed by the percentage of time the intra-esophageal pH was below four (% time pH < 4), number of refluxes, reflux episodes/hour and longest reflux episode, p < 0.05 between upright and supine for each parameter. The median total % time pH < 4 on the proximal and distal probes was respectively 1.62 percent (95% CI 1.50-3.79) and 11.49 percent (95% CI 8.81-27.17), p < 0.0003. Among the 17 hoarse children, a pathological GER was observed in 12 (70.5%) at the distal sensor and in three (17.5%) at both sensors. Among the 16 hoarse children with abnormal findings on laryngoscopy, two (12.5%) had diagnosed pathological GER at the proximal and 11 (68.7%) at the distal sensor. The only child with normal findings on laryngoscopy exhibited a pathological GER at both sensors. Our results suggest that chronic hoarseness is associated with a pathological GER. The majority of these documented refluxes occurred when the child was awake.

This study assessed the ability of otolaryngologists to diagnose and grade reflux disease at rigid endoscopy. Twenty-one out of 25 senior otolaryngologists who were questioned by means of a telephone survey said that if they find evidence of reflux disease at rigid endoscopy of the oesophagus and larynx, their practice is to place the patient on a proton pump inhibitor for six weeks without requesting pH and manometry studies, and without referral to a gastroenterologist. Over a two year period, 21 patients were diagnosed as having reflux disease at rigid endoscopy. This was based on the finding of fluid and erythema in the aerodigestive tract and upper oesophagus. Subsequent oesophageal pH and manometry was performed. Nine out of 21 patients were confirmed as refluxers. This demonstrated an accuracy of less than 50 per cent when using these findings to diagnose gastro-oesophageal reflux at rigid endoscopy.

Although the association between gastroesophageal reflux disease (GERD) and laryngeal disorders in adults is well established there is still a lack of information concerning the true extent of the laryngeal complications of GERD in children. The aim of this study was to determine the laryngeal status of children with diagnosed GERD. We sought to identify the initial appearance of their larynges and then to determine the clinical response to antireflux therapy. GERD was recognized in 90/100 children examined. Using 24-h pH monitoring we found that most of the patients experienced episodes of gastroesophageal reflux during the daytime when they were in an upright position. The hallmark of GERD affecting the larynx in our group was posterior laryngitis, which is characterized by erythema of the mucous membrane overlying the arytenoid cartilages and the posterior mucosal wall of the glottis. The findings regarding the effectiveness of therapy were that, in children with severe laryngeal alterations, voice quality improved significantly after 12 weeks of antireflux treatment (p < 0.001) and laryngeal status was significantly better after 6 weeks of treatment (p < 0.001). This study provides evidence that gastroesophageal reflux in children is the underlying cause of inflammatory and morphological lesions, and that antireflux treatment is effective in reducing or eliminating these lesions.
