Background: The differential diagnosis of cystic cervical masses includes thyroid cyst, thymic cyst, thyroglossal duct cyst, branchial cleft cyst, bronchogenic cyst, lymphangioma, and parathyroid cyst (PC). PC is one of the less common causes of cervical masses. Large PCs can manifest with compressive symptoms of the surrounding tissues. Functioning parathyroid cysts are a rare cause of primary hyperparathyroidism and are often mistaken for thyroid cysts. We report a case where a functioning parathyroid cyst presented as a mediastinal mass to emphasize the potential pitfalls associated with their diagnosis and management.?Case: A 59-year-old male patient visited our clinic for an assessment of dyspnea on exertion and mild dysphagia, symptoms that had begun 6 months prior. Chest computed tomography and neck ultrasound scanning revealed a large mediastinal cystic mass of approximately 10.8 × 5.1 cm in size, located inferior to the left thyroid lobe, causing right-lateral displacement of the large vessels, trachea, and esophagus. We performed fine needle aspiration for the cystic mass, wherein we aspirated approximately 100 cc of fluid with the appearance of old blood and tiny crystals. We also measured the parathyroid hormone (PTH) level of the aspirated fluid to be >5000 pg/mL, suggesting that the fluid originated from the parathyroid gland. The patient presented with primary hyperparathyroidism and elevated levels of calcium and PTH. He subsequently underwent successful parathyroidectomy without any postoperative morbidity, which resulted in complete clinical resolution of the presenting symptoms.?Conclusions: The present study reported the case of a man with a giant functional PC extending from the lower neck to the superior mediastinum. Fine needle aspiration and the detection of increased levels of PTH or thyroglobulin in the fluid of the cyst is a valuable diagnostic tool to confirm cystic neck lesions. Functional hyperparathyroidism should always be considered when parathyroid cyst is confirmed, with surgical excision being the treatment of choice in functioning giant PC.

Purpose: The purpose of this study was to compare the 1% chlorhexidine gluconate/61% ethanol (CHG/ethanol), 45% ethanol/18% 1-propanol (ethanol/propanol) and 7.5% povidone-iodine (PVI) scrub with brush to evaluate their antimicrobial effect. Method: Utilizing repeated measures design, 9 nurses participated in the study. Glove juice sampling procedure was used to evaluate microbial hand counts before the surgical hand antisepsis, one minute after hand wash, and after the surgery. Results: Waterless rub using CHG and ethanol combination resulted in a 3.94 log reduction at 1 min and 2.78 log reduction at 3 hrs. Ethanol/propanol resulted in a 2.42 at 1 min and 2.22 at 3 hrs. The traditional scrub using PVI with brush resulted in a 0.94 at 1 min and 0.95 at 3 hrs (p=.003) and 3 hrs (p=.026) after the surgical hand antisepsis. Repeated measures ANOVA results showed that there was a statistically significant difference among group (p=.002). Duncan post hoc test result showed that the PVI was less effective (p<.05) in sterilizing microbials on hands than CHG/ethanol or ethanol/propanol. Conclusion: Both of the two alcohol-based antiseptic rubs are acceptable alternatives to the PVI with brush for surgical hand antisepsis.

The characteristics of precipitation separation and solvent extraction separation of magnesium from the waste bittern were studied experimentally. In the result of precipitation separation, the size of magnesium hydroxide precipitated was not affected on pH, but decreased with increasing the precipitation temperature. The purity of magnesium oxide precipitated was increased with pH beyond pH 11. From the solvent extraction separation, the equilibrium extraction ratio of magnesium was increased with pH and temperature of extraction phase, the concentration of stripping phase, and with decreasing pH of stripping phase. The extractant of Aliquat 336 and Acid 810 mixture was more effective than that of DCH18C6 and D_2EHPA mixture in the extraction separation of magnesium.

Waste fed to the gasification and melting process, is discharged into synthesis gas and slag. Major components of the gasification synthesis gas mainly contains H<sub>2</sub>, CO, CO<sub>2</sub> and CH<sub>4</sub> and it needs to be purified before use. The industrial solid waste was used for gasification and melting in a pilot plant. The major heavy metals in waste are Zn, Cr, Cu, Pb, Ni, Hg, and Cd, etc. Some of the heavy metals in the waste were discharged volatile metallic vapor or particles with synthesis gas, some were discharged molten slag. Purification process consists of quench scrubber, dedust scrubber, neutral scrubber, desulfur scrubber and wet electrostatic precipitator. Therefore wastewater was discharged from this process. This study investigates the behavior of heavy metals during gasification and melting of industrial solid waste. Hg, Pb, Cd and Zn were analyzed in more than 98% of the scrubber wastewater and Hg, Pb, Cd and Zn concentration were 0.0075, 58.8, 3.8 and 854.3 mg/L, respectively. Cr, Cu was analyzed in more than 63%, 43% of the slag, and Cr, Cu concentration were 9,567.7, 8,076.5 mg/L, respectively.

<P>Zingiber mioga (Thunb.) Roscoe (ZM) is a traditional medicine, used to treat inflammatory diseases. The present study aimed to evaluate the inhibitory effects of ZM on the inflammatory response in lipopolysaccharide (LPS)?stimulated RAW264.7 murine macrophage cells and in a mouse model of ovalbumin (OVA)?induced allergic asthma. Mice received OVA sensitization on day 0 and 14, and were challenged with OVA between days 21 and 23. ZM was administered to the mice at a dose of 30 mg/kg, 1 h prior to OVA challenge. In LPS?stimulated RAW264.7 cells, ZM significantly decreased nitric oxide (NO) and tumor necrosis factor (TNF)?α production in a concentration?dependent manner, and mRNA expression of inducible NO synthase (iNOS), TNF?α and matrix metalloproteinase (MMP)?9 was reduced. In addition, treatment with ZM decreased the inflammatory cell count in bronchoalveolar lavage fluid from the mice, and reduced the expression of interleukin (IL)?4, IL?5, IL?13, eotaxin and immunoglobulin E. ZM also reduced airway hyperresponsiveness in OVA?challenged mice, and attenuated the infiltration of inflammatory cells and mucus production in the airways, with a decrease in the expression of iNOS and MMP?9 in lung tissue. In conclusion, the results of the present study indicate that ZM effectively inhibits inflammatory responses. Therefore, it may be that ZM has potential as a therapeutic agent for use in inflammatory diseases.</P>
