mucosa-associated lymphoid tissue. Ocular MALT

We describe marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT) and especially MALT lymphoma occurring in the conjunctiva. Tumors of the conjunctiva and cornea are grouped into two major categories of congenital and acquired lesions. Lymphoid tumors of the conjunctiva are acquired tumors and can occur as an isolated lesion or can be a manifestation of systemic lymphoma. Primary lymphomas of the conjunctiva are extremely rare usually originate from extranodal marginal zone B-cell non-Hodgkin's lymphomas of MALT and occur among older adults with a mean age of 61 years. In the last decade it has been reported that MALT lymphomas may develop in various extraintestinal locations, sometimes even without the presence of a mucosa. Half of MALT lymphomas occur in the gastrointestinal tract. MALT lymphomas of the eye are rare and originate from the conjunctiva and the lacrimal glands.. Studies evaluating the clinical impact of Ga-67-C scintigraphy for MALT-type lymphomas imaging are rare, based on small numbers, heterogenous; groups of patients. Clinical examination, excisional biopsy, histopathology and immunohistochemical studies, computerized tomography and magnetic resonance imaging are also used for the diagnosis of cunjunctival MALT disease. A case of ours gives reason for further discussion. Treatment and follow-up of MALT lymphoma is described.C1 [Yaylali, Olga Taskaya] Pamukkale Univ, Dept Nucl Med, Denzili, Turkey.[Kirac, Fatma Suna] Pamukkale Univ, Dept Eye Dis, Denzili, Turkey.[Guenduez, Kaan] Pamukkale Univ, Dept Pathol, Denzili, Turkey.[Duezcan, Ender] Ankara Univ, Sch Med, Dept Eye Dis, TR-06100 Ankara, Turkey

Scintigraphic evaluation of gallbladder motor functions in H pylori positive and negative patients in the stomach with dyspepsia.

AIM: To evaluate the relationship between gallbladder (GB) motor function and H pylori infection in the stomach. METHODS: All cases (86) underwent the 14C urea breath test (UBT). 14C-UBT was found as positive in 58 and negative in 28 dyspeptic patients. 14C-UBT was accepted as a gold standard test. Clo test and histopathologic examination were compared with the results of 14C-UBT in cases who tolerated upper gastrointestinal endoscopy procedure. Cholescintigraphy with 99mTc-mebrofenin was used to determine the parameters of GB motor function (GB filling and emptying time, half of the emptying time, ejection fraction at 30th and 60th min) in all patients. RESULTS: We found the sensitivity and specificity as 88% and 86% for Clo test and as 89% and 80% for histologic evaluation, respectively. The parameters of GB function were not significantly different in H pylori positive and negative patients. The GB emptying was normal in both groups. Minimum GB filling time was 30 min in 34 of 86 cases (39.5%), filling was not observed in 2 cases. The GB ultrasonography (USG) results were normal for all cases and bile composition abnormality was not determined. CONCLUSION: Our study showed that 14C-UBT is highly reliable method to detect the presence of H pylori. The presence of H pylori infection does ot directly affect the GB function
