Background/AimsGastric stasis in migraineurs remains controversial. The aim of this study is to investigate gastric emptying (GE) time, and any associations between GE parameters and dyspeptic symptoms among patients with functional dyspepsia (FD) and migraine without any gastrointestinal symptoms during the interictal period.MethodsWe enrolled 27 migraine patients, 32 FD patients and 12 healthy people as controls, and performed GE scintigraphy as gastric function test. Gastrointestinal symptoms were evaluated in the FD and migraine.ResultsThe age-adjusted mean gastric half-emptying time in FD (125.51 ± 52.55 minutes) patients was longer than in migraineurs (100.82 ± 23.94 minutes, P = 0.035) and controls (95.25 ± 23.29 minutes, P = 0.021). The percentage of gastric retention was higher in FD than in migraine. However, migraineurs did not show an obvious delayed gastric emptying or an increase of gastric retention when compared to the normal controls. The association between each dyspeptic symptom and GE parameters was not significant, but postprandial fullness and early satiety showed a tendency of delayed GE. In migraineurs, GE time did not show significant association with nausea and vomiting during interictal periods.ConclusionsDelayed GE does not appear to be a mechanism that patients with FD and migraine have in common. Migraineurs without dyspepsia during interictal period had normal GE, and further study for association with FD should be investigated.
Sentinel lymph node biopsy with lymphoscintigraphy has become the standard method for the detection of axillary lymph node metastasis in breast cancer patients. However, there is no standardized radiopharmaceutical. For the detection of axillary lymph node metastasis by lymphoscintigraphy and sentinel node biopsy in patients with breast cancer, we compared the results between subareolar injection of (99m)Tc-tin colloid and injection of (99m)Tc-phytate. This study included 516 breast cancer patients who underwent surgery between 2001 and 2010. Among the 516 patients, (99m)Tc-tin colloid (37-185 MBq) was administered to 412 patients by subareolar injection, and (99m)Tc-phytate (37-185 MBq) was injected in 104 patients. Lymphoscintigraphy was performed with the patients in the supine position, and sentinel node identification was performed by hand-held gamma probe during surgery. Among 412 patients with (99m)Tc-tin colloid, the sentinel node was identified by lymphoscintigraphy in 364 cases (88.3%) and by a gamma probe in 369 cases (89.6%). Among 104 patients with (99m)Tc-phytate, 101 cases (97.1%) were identified by lymphoscintigraphy and 101 cases (97.1%) were identified by a gamma probe. The identification rates by lymphoscintigraphy and gamma probe were superior with (99m)Tc-phytate, as compared with (99m)Tc-tin colloid, with a statistically significant difference (P < 0.05 for both methods). (99m)Tc-phytate is a better choice than (99m)Tc-tin colloid for identification of the sentinel node in breast cancer patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
