A biomechanical model-based deformable image registration algorithm retrospectively deformed each exhale CT to inhale CT. Th ...
BACKGROUND Esophageal cancer is the 7th most common cancer in Iran. The northern part of the country shows the highest incidence for this malignancy. In this study we present some epidemiological and clinicopathological characteristics of patients with esophageal carcinoma in this region. METHODS In a cross sectional study, 238 Esophageal cancer patients were enrolled in a prospective study of neoadjuvant chemo-radiation treatment in a 4-year period (2006- 2009). In an oncology clinic their ep ...
BACKGROUND AND STUDY AIMS Although most submucosal tumors of the esophagus are benign, reliable exclusion of leiomyosarcoma requires histological analysis. However, this is rarely possible with an endoscopic forceps biopsy. In an attempt to establish the diagnosis, and as an alternative to surgery, we present here our experience with the endoscopic removal of submucosal tumors of the esophagus using two different techniques. PATIENTS AND METHODS Sixty-two patients (38 men, 24 women, mean age 4 ...
Identification of the genes that are specifically expressed in either tumor or normal tissue is important for understanding cancer biology. Using differential displays, we obtained one gene which was specifically expressed in normal tissue but is only rarely expressed in carcinoma tissue of the human esophagus. The sequence of this gene was identical with cystatin B, known to be one of the cysteine-proteinase inhibitors, mainly inhibiting cathepsin L. There is little information on the clinical ...
Nearly one quarter of patients with lung cancer present with locally advanced disease where concurrent chemoradiotherapy is the current standard of care for patients with good performance status. Cisplatin-based concurrent chemoradiotherapy consistently showed an improvement in survival compared with sequential chemoradiotherapy, at the expense of an increase in the toxicity profile. Over the past decades, several encouraging biomarkers such as transforming growth factor-beta and radioprotective ...
BACKGROUND Two assays are available to detect anti-skin antibodies in patients with fogo selvagem (FS): indirect immunofluorescence (IIF) and immunoblotting (IB). This study was conducted to compare the sensitivity of these assays in detecting FS antibodies. DESIGN Eighty-nine serum samples of 48 patients with FS and control serum from 15 normal individuals were tested concurrently for the presence of FS antibodies by IIF and IB. IIF studies were conducted using four different substrates: huma ...
A spontaneously aborted human male fetus of 94 mm crown-rump length had multiple malformations including atresia of the esophagus with tracheoesophageal fistula, anorectal agenesis, anomalies of the heart and great vessels, kidneys, bladder, and left testis, and a single umbilical artery. This association of defects has not previously been described in a fetus at this immature stage of development. ...
Out of 81 patients with suspected caustic injury 27% showed esophageal lesions. In 5% the lesions were severe and strictures developed and dilatations were necessary. The diagnosis has to be made by endoscopy in each suspected injury to rule it out or to control its steroid therapy. Even without oropharyngeal lesions caustic injury of the esophagus is possible. Endoscopy and dilatation were made under sedation and did not hurt the patients. No complications occurred. Steroids seem to be useful o ...
BACKGROUND Although morphologic, radiographic, and manometric features of achalasia have been well defined, it has not been established by careful retrospective analysis whether achalasia is a progressive disorder resulting in complete decompensation. STUDY DESIGN To verify the hypothesis that achalasia is a progressive disease, we retrospectively investigated manometric, radiographic, and symptomatic data in patients with achalasia. Sixty-three patients (36 women and 27 men) with a median age ...
Fanconi anemia is a rare autosomal recessive disease characterized by multiple congenital anomalies, pancytopenia, and cancer susceptibility, especially to leukemia and squamous cell carcinoma of the head and neck or esophagus. F-FDG PET/CT is a useful tool to assess tumor staging and follow-up of esophageal cancer. We report a rare case of cervical esophageal cancer and lymph node metastases detected on F-FDG PET/CT in a patient with Fanconi anemia after bone marrow transplantation. ...
Clinical findings, symptoms and predisposing factors were studied in 43 patients with oesophageal candidiasis, 40 patients with peptic oesophagitis and 40 normal controls. Oesophageal candidiasis was confirmed cytologically. 2.4% of patients who had undergone gastroscopy had oesophageal candidiasis; only three of them had simultaneous candidiasis of the oral cavity. Cardiac failure, oesophageal varices, hiatus hernia and gastric ulcer were common associated disorders. 42% of patients with candid ...
Intake of a variety of foods increases the likelihood of good general health. From as early as life in utero, humans are exposed to flavor. Further flavor imprinting occurs via breast milk, increasing the likelihood of acceptance of a variety flavors when solids are introduced. While first foods need to be smooth and runny, experience managing soft lumps is required for rudimentary development of chewing skills. Texture experiences are critical to providing building blocks for food acceptance an ...
A 26-year-old woman with no history of mental illness presented to the emergency department and stated that she had accidentally swallowed the toothbrush when carrying out dental care. She was asymptomatic, A plain abdominal radiograph confirmed the presence of a foreign body in the left upper quadrant (Figure 1). During gastroscopic examination (Olympus G I F X Q 1 0 ) , the toothbrush was visualized in the stomach. Endoscopic removal was carried out after premedication with midazolam. The head ...
This single-blind crossover trial compared the effects of single oral doses of two antacids on esophageal and gastric pH in subjects with heartburn. Gastric and esophageal pH were assessed in 83 subjects from 1 h before to 4 h after a refluxogenic meal. Subjects received two chewable tablets of a high-potency aluminum/magnesium hydroxide [Al(OH)3/Mg(OH)2] formulation (Mylanta Double-Strength(TM)) or a calcium carbonate [CaCO3] formulation (Tums E-X(TM)), or placebo 1 h after the meal. Both antac ...
Esophageal foreign bodies are common, especially in children less than 5 years old. However, the presence of an open safety pin in the esophagus is quite rare. When this occurs, immediate removal of the safety pin is recommended due to its propensity to pierce the esophagus and surrounding structures causing severe and sometimes even lethal complications. Between the years 1990 and 2003, fifteen infants were referred to the Department of Otolaryngology-Head and Neck Surgery at the Rambam Health ...
The lower esophageal sphincters (LES) together with the crural diaphragm are the major antireflux barriers protecting the esophagus from reflux of gastric content. However, reflux of gastric contents into the esophagus is a normal phenomenon in healthy individuals occurring primarily during episodes of transient lower esophageal sphincter relaxation (TLESR), defined as LES relaxation in the absence of a swallow. Transient lower esophageal sphincter relaxation is also the dominant mechanism of pa ...
The patient was a 69-year-old man who, during a routine health examination, was found to have irregular mucosa in the lower esophagus, which was subsequently diagnosed by endoscopy as Barrett's esophagus. Endoscopic ultrasonography led to the diagnosis of advanced esophageal cancer with a depth of invasion corresponding to T2. While surgery was indicated, it was not considered feasible because of pleural adhesions due to old tuberculosis. Therefore, chemotherapy with TS-1 at the dose of 80 mg/da ...
Over an 11-year period 1158 patients with esophageal cancers were managed by the Department of Surgery, The University of Hong Kong, Queen Mary Hospital, 857 (74.0%) of whom had confirmed squamous cell carcinoma. Operation was carried out in 76.5% of patients: 25.4% underwent curative resection, 36.2% underwent palliative resection, 13.8% had bypass operations, and 1.2% had a simple exploration. In the resection group, the mean age was 62.6 years with a strong male predominance of 6.4:1.0. Most ...
Epidermal growth factor (EGF) effects have been explored extensively in vivo in rodents, but little is known about trophic responses in nonhuman primates. A previous publication reports the hyperplastic epithelial/parenchymal changes noted in the digestive tract (tongue, esophagus, stomach, intestine, liver, gallbladder, pancreas, and salivary glands) of adult cynomolgus monkeys treated with recombinant human EGF(1-48) (rhEGF(1-48)). This report documents clinical findings and structural effects ...
BACKGROUND The analysis of circulating tumor cells (CTCs) is emerging as a promising diagnostic tool in oncology. However, even if a variety of methods for CTC isolation have been already developed, their specificity and/or sensitivity still remain problematic. The aim of this study was to develop an immunomagnetic/real-time reverse transcription polymerase chain reaction (RT-PCR) assay for the molecular detection of circulating tumor cells (CTCs) in peripheral blood (PB) of adenocarcinoma cance ...
Experimental and clinical results of use of fibrin glue for strengthening "high risk" sutures of anastomoses in elective surgery of the esophagus, stomach and urgent abdominal surgery are presented. In experimental studies this glue permitted to increase mechanical strength and containment of anastomosis, to accelerate microbial elimination, activated reparative processes. In clinical practice fibrin glue permitted to avoid suture insufficiency of gastrointestinal anastomoses in the most unfavor ...
INTRODUCTION G astroesophageal reflux disease (GERD) is extremely common and encompasses a diverse spectrum of clinical presentations. It has a substantial impact on patient quality of life and use of health care resources (1). GERD results from failure of the lower esophageal sphincter (LES) and cardia to prevent return of gastric contents into the esophagus. The pathophysiology of GERD is multifactorial and includes the occurrence of inappropriate, non-swallow related LES relaxations, and low ...
A 65-year-old man was followed up after endoscopic mucosal resection for esophageal cancer in February 2000. Thereafter, he received endoscopic mucosal resection, radiation therapy, and argon plasma coagulation for recurrent and multiple primary esophageal cancers. On follow-up examination, two additional esophageal cancers were detected by endoscopy in September 2003. One lesion was located 16 cm from the incisor close to the entrance to the esophagus. To preserve the larynx, this lesion was re ...
Resection of the achalasic area and replacement by a segment of jejunal loop, associated with vagotomy and pyloroplasty, has been performed in 21 patients. The majority of these patients had Chagas' disease, with a dilated esophagus wider than 7 cm. This surgical procedure offered symptomatic relief in 20 of our 21 cases. One patient died, but the death was not necessarily related to the operation. Although disphagia and regurgitation did not disappear entirely in all cases the decrease in sever ...
One hundred and ninety seven patients with cancer of the hypopharynx underwent after circular resection, reconstruction with a free jejunal graft. The quality of free jejunal grafts is controlled by many investigations: clinical examination, radiography, electromyography, fibroscopy with biopsy. These investigations show that technically jejunal grafts must be short and linear to give the best functional results. Average resumption of oral intake was 14 days. Oral feeding was possible in 92% of ...

METH ...
We report a case of an 83-year-old man with history of coronary artery disease and gastroesophageal reflux disease (GERD) who presented with sudden onset nocturnal dyspnea. He was diagnosed with non-ST elevation myocardial infarction based on the electrocardiographic changes and cardiac biomarker elevation. Cardiac catheterization revealed chronic three-vessel coronary artery disease, with 2 patent grafts and 2 chronically occluded grafts. While at the hospital, the patient experienced a similar ...
onds, albumin 3.8 gm/dL, and normal liver function tests. She was admitted to the intensive care unit for further management. An upper GI endoscopy was performed, which revealed normal esophagus, large hiatus hernia, and normal stomach and duodenum. Upon withdrawing the gastroscope while examining the hypopharynx and oropharynx, a large varix was noticeable in the oropharynx, with stigmata of a recent bleed (Fig. 1). The next day, her Hb was 6.9 without any further evidence of active bleeding. S ...
Meningeal carcinomatosis (MC) is an uncommon from of metastasis of solid tumors. We reported a clinical case of a woman with esophagus adenocarcinoma that a few months after surgical operation, presented episodes of vomiting, nausea, hypertension, mental change, unconsiousness; A contrast-enhanced CT of the brain revealed an "area of enhancement in the caudate nucleus" and cerebrospinal fluid cytologic studies evidenced the presence of carcinomatous cells. The clinical state of the patient deter ...
Primary small-cell carcinoma of the esophagus is an uncommon esophageal malignancy. This report details the clinical and pathologic aspects of 11 cases seen at our institution over 20 years, as well as 123 other cases reported in the literature. Small-cell carcinomas of the esophagus show considerable histologic heterogeneity. Neurosecretory granules can be found in the majority of cases and some show evidence of multidifferentiation. Like primary small-cell cancers of the lung, those in the eso ...
Mathematical models based on relaxation oscillators have heavily influenced the terminology and experimental designs of investigations in gastrointestinal motility for nearly two decades. Relaxation oscillator equations have been used to stimulate the electrical activities of the esophagus, stomach, small intestine, colon, and rectosigmoid region. It has been suggested that many attributes of gastrointestinal electrical activity cannot be adequately explained by classic "core-conductor" or "cabl ...
Most infants with long-gap esophageal atresia receive an esophageal replacement with tissue from stomach or colon, because the native esophagus is too short for true primary repair. Tissue-engineered esophageal conducts could present an attractive alternative. In this paper, circular decellularized porcine esophageal scaffold tissues were implanted subcutaneously into Sprague-Dawley rats. Depending on scaffold cross-linking with genipin, glutaraldehyde, and carbodiimide (untreated scaffolds : po ...
Quantitative differences in submucous plexus density were sought in cat and opossum gut by examining full-thickness whole mounts of the submucosa stained with silver, and counting ganglia per square centimeter and nerve cell bodies per ganglion in order to compute density of innervation (nerve cell bodies per square centimeter). In the cat, the nerve cell bodies per square centimeter in the 12 named regions were as follows: proximal esophagus, 0; mid-esophagus, 0; distal esophagus, 0; fundus, 84 ...
Laryngopharyngeal reflux (LPR) is becoming recognized as a clinical entity with a variety of presentations distinct from those of gastroesophageal reflux disease (GERD). However, much uncertainty remains as to what is considered pathologic versus physiologic reflux. The aim of the study was to determine the normal range of pharyngeal reflux (PR) occurring in healthy adults based on pH-monitoring parameters utilized in the DeMeester scoring system for GERD. We have reviewed the current pool of pr ...
BACKGROUND After laryngectomy for treatment of pharyngeal/laryngeal carcinomas the patients may be rehabilitated, for oral communication, with the esophageal speech. AIM To study the intra-esophageal pressure during the esophageal speech. PATIENTS AND METHODS It was measured the intra-esophageal pressure in 25 laryngectomized patients aged 40 to 70 years (median 57 years), 10 rehabilitated with esophageal speech and 15 unable to do so. The manometric method with continuous perfusion was used ...
Clinicopathologic features and clinical outcomes of gastrointestinal stromal tumors (GISTs) in esophagus are limited, because of the relatively rare incidence of esophageal GISTs. Therefore, the aim of the current study was to investigate the clinicopathologic features and clinical outcomes of esophageal GISTs, and to investigate the potential factors that may predict prognosis.Esophageal GIST cases were obtained from our center and from case reports and clinical studies extracted from MEDLINE. ...
We report a 71-year-old man with rectal carcinoid accompanying carcinomas of the esophagus and ureter. These were synchronous triple cancers clinically diagnosable and curable. Pathohistologically, positive granules were observed upon Grimelius and Masson-Fontana staining. The production of multiple hormones was indicated by electron microscopy and histochemical studies (PAP method). ...
To explore cancer incidence among Hispanic women living in Dade County, Florida, data were analyzed from the statewide cancer registry. For all but three sites, Hispanics had lower rates of the 15 most prevalent cancers than non-Hispanics. However, higher rates of cancer among Hispanics were noted for cancers of the gallbladder, liver, and heart and soft tissue. Subgroups of women had significantly higher rates of cervical cancer and thyroid cancer. Lower rates among Hispanics were observed for ...
OBJECTIVES The locally advanced esophageal carcinoma can be complicated by fistulas. According to published data, the incidence rate of malignant esophageal fistulas is about 13%. The range of treatment modalities proposed by different authors varies from palliation to active and, if possible, radical surgical interventions. In the present study, we investigated combined esophagectomies as a radical treatment of the malignant esophageal fistulas. METHODS Thirty-five patients (aged 28--67) with ...

OBJECTIVE The purpose of this retrospective study is to present 13 patients with an initial diagnosis of BP, who subsequently demonstrated coexistent serological features of both BP and PV. METHODS The following information on each patient was documented, at the time of initial diagnosis: clinical profile on presentation, histolo ...
Infection with Mycobacterium tuberculosis is frequently found in patients with acquired immunodeficiency syndrome and can result in diffuse lymphadenopathy from disseminated disease. A case is presented of esophageal erosion and perforation secondary to mediastinal lymph node enlargement from Mycobacterium tuberculosis in a patient positive for human immunodeficiency virus. Emergent surgical intervention required resection of the perforated esophagus, end-cervical esophagostomy, gastrostomy, and ...
This is a review of the geographic distribution of oropharyngeal cancers and of chewing habits which involve various plant materials and additives including lime. Cancers in the oropharynx and esophagus may be induced by the same carcino gens. Suspected plant carcinogens in the environments of patients with high frequencies of cancers of the oropharynx or esophagus are being tested in hamster cheek pouches which have been treated with calcium hydroxide (lime). ...
Superoxide (O2-)-generating activity of blood monocytes, the precursors of macrophages, from patients with advanced cancer and/or infection was studied. Monocytes from normal subjects generated 0.288 +/- 0.022 nmol O2-/min/10(5) cells (mean +/- S.E.M., n = 36) after sequential stimulation with cytochalasin E and wheat germ agglutinin. Monocytes from 69 non-infected adult patients with advanced malignancy of the stomach, esophagus and liver, and 7 pediatric patients with neoplastic disease releas ...
BACKGROUND AND PURPOSE We investigate whether knowledge based planning (KBP) can identify systematic variations in intensity modulated radiotherapy (IMRT) plans between multiple campuses of a single institution. MATERIAL AND METHODS A KBP model was constructed from 58 prior main campus (MC) esophagus IMRT radiotherapy plans and then applied to 172 previous patient plans across MC and 4 regional sites (RS).
