Many sensitizing chemicals and additives are used in manifacturing and mending dentures. Among them, phtolyldiethanolamine, a kind of accelerto for polymerization, is necessary only in self-curing acrylic resins which are available for repairing and relining of denture. Although the sotirce of denture stomatitis is still controversial, a true allergy to denture base materials can be recognized by a patch test. We report a case of allergic contact stomatitis due to dentn e relining materials in a 65-year-old denturecariying edentulous patient. Patch testievi.aled positive reaction to polyldiethanolamine which is considerd to be contained in a cold curing acrylic resin fluid.

We present the cytologic features of a case of solid and papillary neoplasm of the pancreas. Cytologically, the tumor was composed of a monotonous population of polygonal cells containing eccentrically located round nuclei with one or two distinct small nucleoli and a finely stippled chromatin pattern. The tumor cells were similar to those of the islet cell tumor and showed isolated loosely aggregated and solid sheets or large cell clumps. The large cell clumps revealed a branching papillary structure containing fibrovascular central core, which is characteristic histologic feature of solid and papillary neoplasm of the pancreas. This case was confirmed by tissue examination including histochemical, immunohistochemical and electron microscopical studies. Ultrastructurally, the tumor cells contained a few membrane-bound electron dense granules.

Electron microscopy (EM) can provide a valuable contribution to light microscopy (LM) in the interpretation of fine needle aspiration cytology (FNAC) specimen, especially in the diagnosis of the tumor. However, considerable care in processing the specimen is mandatory to recover the cells and avoid altering the fine structures. We experienced a case of malignant melanoma in 33-yrs-old female, diagnosed by EM study of FNAC specimen from the axillary mass, who was initially thought as dissem- inated carcinomatosis on LM study. The technique of EM study on FNAC specimen consisted of washing the needle and syringe in 2.5% glutaraldehyde after a rapid stain (Diff-Quik), which was used to obtain a preliminary diagnostic impression and to assure the adequacy of the EM specimen. After centrifugation in the steps of fixation and dehydration, the sediment was made into an epon block and examined. The whole processing time of EM study can be shortened within 7 or 8 hours, and results can be available within 48 to 72 hours. Our experience suggests the EM study on FNAC can be a useful diagnostic method in the diagnosis of difficult FNAC cases.

BACKGROUND: There are many suggested methods for the indirect determination of anaerobic threshold(AT) using the changes of ventilatory parameters in respones to ventilatory load accompanying the increase of blood lactic acid level during exercise and the threshold derived from them is called ventilatory threshold( VT). They include ventilatory equivalent method(VEM), End-tidal PO2 method(PETO2), V-slope method(VSM), and respiratory quotient method(RQ). But in the patients with chronic airway ohstruction(CAO), the AT determined by ventilatory methods may not reflect true AT because the patients with GAO show inadequate ventilatory response to the increase of blood lactic acid level during excercise. METHODS: For the investigation of detection rate and reliability of above four VT determination methods in the patients with GAO, we performed the symptom-limited and maximal incremental exercise test in 17 patients with GAO and 12 normal controls. The incremental workload was 10 W/min in GAO group and 25 W/min in control group. The reliability of VT in each group was investigated by the calculation of Spearman correlation coefficient. RESULTS: The detection rates of VT were 100% by RQ, 91.7% by both VEM and POETO2, and 83.3% by VSM in normal control group, while 94.1% by RQ, 64.7% by VEM and PETO2, and 83.3% by VSM in GAO group. Good correlations were noted among VEM, PETO2, and VSM except RQ in normal control group. But there was no significant correlation except between VEM and PETO2 in GAO group. CONCLUSIONS: RQ is very sensitive but crude and VEM is near similar to PETO2. The clinical usefulness of VT determined by ventilatory method might be limited in patients with severe GAO.
