The relationship between heterotopic gastric mucosa in the cervical esophagus and laryngopharyngeal reflux.

OBJECTIVES: This study aims to investigate the possible correlations between the heterotopic gastric mucosa (HGM) islets in the cervical esophagus and laryngopharyngeal reflux (LPR). PATIENTS AND METHODS: Between May 2010 and April 2011, 45 patients (36 females, 9 males; mean age 39.8±14.1 years; range 18 to 72 years) who had reflux symptom index (RSI) >10 and reflux finding score (RFS) >7 were included. The study group consisted of 21 patients who were diagnosed with HGM islets in the cervical esophagus, while control group consisted of 24 patients without any HGM islets assessed by upper gastrointestinal system endoscopy. Esophagus manometric examination and dual-channel 24-hour pH monitoring were performed on all patients. RESULTS: Pretreatment mean RSI and RFS were 25.6±3.5 and 15.1±3.4 in group 1, while it was found to be 21.1±4.4 and 11.9±2.6 in group 2 (p=0.001, p=0.001). A total of 29.7% of patients who underwent pH monitoring had distal reflux, whereas 43.2% of them had proximal reflux. In group 1, distal reflux was observed in 15.4% and proximal reflux was found in 54% of the patients, while distal reflux was observed in 38% and proximal reflux was found in 38% of the patients in group 2 (p=0.152; p=0.27). Fourteen patients diagnosed with HGM had antral- and seven patients had fundal-type epithelium. CONCLUSION: Our study results suggest that HGM islets may be considered as an etiological factor in the patients with severe LPR with isolated proximal reflux based on the 24-hour pH monitoring.

Primary cardiac undifferentiated sarcoma: role of intraoperative imprint cytology and frozen section of two cases.

Primary cardiac tumors are very rare, and a vast majority of such malignant tumors are sarcomas. Associated symptoms are usually vague and nonspecific resulting in a late diagnosis and poorer prognosis. Most cardiac sarcomas have been reported in autopsy series. Although echocardiography may help make a diagnosis of a cardiac sarcoma, histopathological confirmation is quintessential. Presented here are two cases of patients who underwent successful surgery for the removal of a cardiac tumor, along with echocardiographic, cytological, and histopathological findings as well as a compact literature review. In both patients, the masses were on the surface of the mitral valve, and intraoperative evaluation of frozen sections and imprint cytology were indicative of a "probably malignant" mesenchymal tumor prompting more extensive surgical resection. Immunohistochemical staining of the resected material in both cases was only positive for vimentin, leading to a diagnosis of undifferentiated sarcoma. One of the patients died 3 months after surgery, while the other who received adjuvant chemotherapy was still alive after 4 months. Surgery remains the most definite treatment for cardiac sarcomas. The use of intraoperative frozen section and imprint cytology plays an important role in the decision to extend surgical resection.
