BACKGROUND: Eosinophilic gastritis is related to eosinophilic gastroenteritis, varying only in regards to the extent of disease and small bowel involvement. Common symptoms reported are similar to our patient's including: abdominal pain, epigastric pain, anorexia, bloating, weight loss, diarrhea, ankle edema, dysphagia, melaena and postprandial nausea and vomiting. Microscopic features of eosinophilic infiltration usually occur in the lamina propria or submucosa with perivascular aggregates. The disease is likely mediated by eosinophils activated by various cytokines and chemokines. Therapy centers around the use of immunosuppressive agents and dietary therapy if food allergy is a factor. CASE PRESENTATION: The patient is a 31 year old Caucasian female with a past medical history significant for ulcerative colitis. She presented with recurrent bouts of vomiting, abdominal pain and chest discomfort of 11 months duration. The bouts of vomiting had been reoccurring every 7-10 days, with each episode lasting for 1-3 days. This was associated with extreme weakness and cachexia. Gastric biopsies revealed intense eosinophilic infiltration. The patient responded to glucocorticoids and azathioprine. The differential diagnosis and molecular pathogenesis of eosinophilic gastritis as well as the molecular effects of glucocorticoids in eosinophilic disorders are discussed. CONCLUSIONS: The patient responded to a combination of glucocorticosteroids and azathioprine with decreased eosinophilia and symptoms. It is likely that eosinophil-active cytokines such as interleukin-3 (IL-3), granulocyte macrophage colony stimulating factor (GM-CSF) and IL-5 play pivotal roles in this disease. Chemokines such as eotaxin may be involved in eosinophil recruitment. These mediators are downregulated or inhibited by the use of immunosuppressive medications.

Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products. In industry, the principal use of hydrogen peroxide is as a bleaching agent in the manufacture of paper and pulp. Hydrogen peroxide has been employed medicinally for wound irrigation and for the sterilisation of ophthalmic and endoscopic instruments. Hydrogen peroxide causes toxicity via three main mechanisms: corrosive damage, oxygen gas formation and lipid peroxidation. Concentrated hydrogen peroxide is caustic and exposure may result in local tissue damage. Ingestion of concentrated (>35%) hydrogen peroxide can also result in the generation of substantial volumes of oxygen. Where the amount of oxygen evolved exceeds its maximum solubility in blood, venous or arterial gas embolism may occur. The mechanism of CNS damage is thought to be arterial gas embolisation with subsequent brain infarction. Rapid generation of oxygen in closed body cavities can also cause mechanical distension and there is potential for the rupture of the hollow viscus secondary to oxygen liberation. In addition, intravascular foaming following absorption can seriously impede right ventricular output and produce complete loss of cardiac output. Hydrogen peroxide can also exert a direct cytotoxic effect via lipid peroxidation. Ingestion of hydrogen peroxide may cause irritation of the gastrointestinal tract with nausea, vomiting, haematemesis and foaming at the mouth; the foam may obstruct the respiratory tract or result in pulmonary aspiration. Painful gastric distension and belching may be caused by the liberation of large volumes of oxygen in the stomach. Blistering of the mucosae and oropharyngeal burns are common following ingestion of concentrated solutions, and laryngospasm and haemorrhagic gastritis have been reported. Sinus tachycardia, lethargy, confusion, coma, convulsions, stridor, sub-epiglottic narrowing, apnoea, cyanosis and cardiorespiratory arrest may ensue within minutes of ingestion. Oxygen gas embolism may produce multiple cerebral infarctions. Although most inhalational exposures cause little more than coughing and transient dyspnoea, inhalation of highly concentrated solutions of hydrogen peroxide can cause severe irritation and inflammation of mucous membranes, with coughing and dyspnoea. Shock, coma and convulsions may ensue and pulmonary oedema may occur up to 24-72 hours post exposure. Severe toxicity has resulted from the use of hydrogen peroxide solutions to irrigate wounds within closed body cavities or under pressure as oxygen gas embolism has resulted. Inflammation, blistering and severe skin damage may follow dermal contact. Ocular exposure to 3% solutions may cause immediate stinging, irritation, lacrimation and blurred vision, but severe injury is unlikely. Exposure to more concentrated hydrogen peroxide solutions (>10%) may result in ulceration or perforation of the cornea. Gut decontamination is not indicated following ingestion, due to the rapid decomposition of hydrogen peroxide by catalase to oxygen and water. If gastric distension is painful, a gastric tube should be passed to release gas. Early aggressive airway management is critical in patients who have ingested concentrated hydrogen peroxide, as respiratory failure and arrest appear to be the proximate cause of death. Endoscopy should be considered if there is persistent vomiting, haematemesis, significant oral burns, severe abdominal pain, dysphagia or stridor. Corticosteroids in high dosage have been recommended if laryngeal and pulmonary oedema supervene, but their value is unproven. Endotracheal intubation, or rarely, tracheostomy may be required for life-threatening laryngeal oedema. Contaminated skin should be washed with copious amounts of water. Skin lesions should be treated as thermal burns; surgery may be required for deep burns. In the case of eye exposure, the affected eye(s) shod eye(s) should be irrigated immediately and thoroughly with water or 0.9% saline for at least 10-15 minutes. Instillation of a local anaesthetic may reduce discomfort and assist more thorough decontamination.

The aim of the prospective clinical study presented here is to test the effectiveness of a multimode approach consisting of argon plasma coagulation combined with laparoscopic fundoplication in the management of Barrett's esophagus. Argon plasma coagulation was performed in 19 patients with Barrett's esophagus who had previously undergone surgical antireflux treatment. The mean follow-up time was 17 months, ranging between 6 and 27 months. Squamous epithelium was completely restored in all patients. In 68.4% of cases two sessions were required. The most frequent complications were chest discomfort and retrosternal pain. In 11 patients the symptoms lasted 3 days and in six cases persisted for a longer period, requiring analgesic medication. Short-term dysphagia and odynophagia were observed in four patients.

Surface electromyographic (sEMG) studies were performed on 300 normal adults to estimate normal values of sEMG records of muscle activity in the detection and evaluation of stages of normal swallowing. Our study was a prospective observational study of healthy volunteers. The parameters evaluated during swallowing include the timing, amplitude (voltage), and graphic patterns of activity of the orbicularis oris, masseter, submental, and laryngeal strap muscles covered by the platysma. Three tests were examined: voluntary single swallows of saliva ("dry" swallow), voluntary single water swallows ("normal"), and voluntary single swallows of excessive amounts of water (20 ml, "stress test"). Duration and amplitude of muscle activity in oral, pharyngeal, and initial esophageal stages of swallowing (mean + standard deviation, range + standard deviation) were measured for groups of adults of different ages (18-40, 41-70, 70+ years). Shapes of graphic records were evaluated relative to timing and voltage. The overall normal mean values for stage-by-stage duration of muscle activity during single swallowing were established for healthy adults. The duration of muscle activity in all tests showed insignificant increases with age except for the elderly group (70+) in which it was statistically significant (SPSS, chi2 criterion, 95% confidence interval, p < 0.05). There were no statistically significant gender-related differences in duration or amplitude of muscle activity during single swallowing for any age group (p > or = 0.05). We conclude that the rectified and filtered sEMG provides a noninvasive means to assess certain aspects of complex muscle activity in deglutition. Surface EMG of swallowing is a simple and reliable noninvasive screening method for evaluating swallowing with low levels of discomfort. Stage-by-stage evaluation of duration can be very important for diagnosing the etiology of dysphagia. The combined normative timing of events, amplitude, and graphic data can be used for evaluating complaints and symptoms, as well as for comparison purposes in pre- and postoperative stages and in EMG monitoring during otolaryngological or neurological treatment. These parameters represent stages required for normal deglutition and provide a basis for the comparison of swallowing performance both within and between patients.

One important complication of tracheostomy procedure is the depressed scar left after the airway is removed. The problem is more challenging for the surgeon if tracheal tug accompanies. Six male patients with unaesthetic, depressed tracheostomy scars due to late removal of tracheostomy tubes after maxillofacial high-velocity gunshot injuries were treated. The patients' age ranged from 20 to 23 years, with an average age of 21 years. The mean tracheostomy tube removal time was 18 days (range, 9 to 34 days) postoperatively. The mean scar dimension was 13.4 mm x 14.4 mm x 4 mm (width, length, and depth, respectively). All patients showed tracheal tug and complained of swallowing discomfort. Under local anesthesia, split sternocleidomastoid muscle flaps were used bilaterally following excision of the skin scars and covered by adjacent skin flaps. The mean follow-up was 18 months. Cosmetic and functional results were satisfactory for all patients. Dysphagia disappeared in all patients following surgery. This technique is useful and easy to perform for reconstruction of complex post-tracheostomy scars.

In reviewing the literature, there are few articles describing the role of the speech-language pathologist in hospice. Communication impairments can impact upon the hospice team's ability to provide symptom control and supportive psychosocial care, and diminish the patient's ability to guide the decision making process and maintain social closeness with family. Swallowing difficulties may result in discomfort for patients and concern from caregivers. Patient care provided by the speech-language pathologist can align with the framework of the World Health Organization's components of palliative care. Four primary roles of the speech-language pathologist in hospice can be described. (1) To provide consultation to patients, families, and members of the hospice team in the areas of communication, cognition, and swallowing function; (2) To develop strategies in the area of communication skills in order to support the patient's role in decision making, to maintain social closeness, and to assist the client in fulfillment of end-of-life goals; (3) To assist in optimizing function related to dysphagia symptoms in order to improve patient comfort and eating satisfaction, and promote positive feeding interactions for family members and (4) To communicate with members of the interdisciplinary hospice team, to provide and receive input related to overall patient care. Further development of the speech-language pathologist as a participating member of the hospice interdisciplinary team would support the overall goal of providing quality care for patients and families served by hospice.

Laparoscopic Nissen, Nissen-Rossetti, cardial calibration with gastropexy, and other modifications are the procedures commonly used for surgical treatment of gastroesophageal reflux disease. Postoperative failures have been reported ranging from 10% to 15% associated with postoperative symptoms or recurrent gastroesophageal reflux. In this paper, we present 38 patients submitted to different procedures in which different "abnormal" deformities were found during the postoperative radiological evaluation with barium swallow. The symptoms associated with these deformities were pain (62%), dysphagia (43%), early satiety (37%), postprandial discomfort (35%), and recurrent postoperative reflux (30%). Dysphagia and pain were frequently observed after the Nissen-Rossetti technique, in which a bilobed stomach and stricture (46%) were confirmed. Hiatal hernia was observed in two patients, and slipped Nissen in one patient associated to pain and early satiety. Patients were submitted to conservative treatment (endoscopic dilatation, proton pump inhibitors, and prokinetics), but 10 patients were submitted to redo surgery. There were no complications, and good results were obtained after redo operations.

We report a severe unilateral recurrent laryngeal nerve neuropraxia following use of the ProSeal laryngeal mask airway (PLMA) in a 71-year-old female patient with CREST syndrome. She required amputation of the 5th phalanx of foot because of gangrene due to Raynaud's syndrome. Anesthesia was induced with propofol, and a size 3 PLMA was inserted. Anesthesia was maintained with sevoflurane and nitrous oxide for 2 h and the operation was performed uneventfully. On removal of PLMA, the cuff volume was measured to 40 ml. The patient did not complain of respiratory discomfort shortly after PLMA removal. However, the next day she developed dysphagia and hoarseness. Laryngoscopic examination revealed unilateral vocal cord paralysis. Cricothyrotomy was required because of suspected silent aspiration pneumonia. The pharyngolaryngeal complications improved with a mobile vocal cord but slight hoarseness after 2 months. We considered the patient's CREST syndrome with a potential of tissue ischemia, and the high intracuff pressure of the PLMA due to nitrous oxide influx, to be the cause of severe recurrent laryngeal nerve neuropraxia in this case.

Gastroesophageal Reflux disease (GERD) has a common clinical presentation of a burning discomfort in the retroesternal area, regurgitation and dysphagia. Yet, an estimated of 20 to 60 percent of patients with GERD have head and neck symptoms without any appreciable heartburn. Careful history and a meticulous physical exam can guide us to have a correct diagnosis and give adequate treatment. Other methods, such as gastroscopy and gastric pH monitoring, as well as other diagnostic studies can help us to confirm the diagnosis. Once we have the correct diagnosis stabilized, life style modification should be the first step in the management of GERD, aided with antacids, H2 receptors antagonists and/or Proton pump inhibitors. Family physicians should be aware that helping patients to understand the cause of their symptoms and reinforcing the life style modifications will bring better control of the disease and patients can have improvement of their symptoms leading to possible cure of the disease. Gastroesophageal Reflux Disease (GERD) is defined as the movement of gastric contents into the esophagus without presence of vomiting. It is frequently associated with heartburn, the sensation of burning discomfort in retrosternal area, that moves upward, toward the throat. GERD is a chronic, relapsing condition with associated morbidity and adverse impact on quality of life. The purpose of this article is to give an overall look at the clinical presentations of GERD with typical and atypical symptoms, the various presentations of this disease in all of the age groups, and to identify all of the aspects that contribute to the progression and solution of this problem.

A rare case of primary large B-cell non-Hodgkin lymphoma of the larynx is reported. The patient was an 80-year-old female who presented with pharyngeal discomfort and dysphagia. Radiotherapy was instituted with complete remission of the tumor. Nine months afterward, she presented with aspiration pneumonia and dysphagia. Indirect laryngoscopy disclosed laryngeal and esophageal edema, which was probably related to radiotherapy. No signs of tumor recurrence were observed. Three months later, she was entirely asymptomatic. Although cases of aggressive course and poor response to therapy exist, primary large B-cell non-Hodgkin lymphoma of the larynx is generally considered a relatively benign and radiosensitive tumor.
