Background:
One of the eight Ramsar sites in the Philippines is the Las Piňas – Parañaque Critical Habitat and Ecotourism Area(LPPCHEA), and it plays a significant role in the East Asian-Australian Flyway as a stopover site. The migratory birds coming from the north of Asia and Alaska feed on the molluscs in this area. However, there is paucity of literature on the species composition of molluscs found in this critical habitat. Baseline information on these organisms is essential as they are subject to the effects of anthropogenic activities close to and in the wetland, which in turn can have an impact on the ecosystem, particularly the birds foraging in this location.
Methodology:
The Natural Geography of in-Shore areas (NaGISA) protocol was used for the study. Transects were laid in three sampling sites in Freedom Island and Long Island. The sampling sites were GPS-referenced. A cylinder corer was used to collect mudflat soil, with the corer pushed into the sediment. Soil samples were sieved using a 0.5mm stainless mesh sieve pan, leaving shells and larger sand grains. The molluscs were sorted and identified through taxonomic keys. Sampling was done once for each site in November 2012.
Results and Discussion:
A total of 61 molluscan species belonging to two classes, 14 orders, and 33 molluscan families were identified and recorded. There were 34 species under the Class Gastropoda that belong to 5 orders and 18 families. For Class Bivalvia, there were 27 species belonging to 8 orders and 15 families. Among the molluscs recorded, 10 species were identified as non-indigenous. It is important to monitor molluscan species as anthropogenic activities may affect these organisms, and in turn, affect the wetland's function for migratory birds. The presence of non-indigenous species may be a potential threat to the ecosystem.
Conclusion
Baseline information of the molluscan community in the LPPCHEA was provided by the study. These species provide diet to the endemic and migratory birds in the area. There is a need to monitor these molluscs due to the effects of the man-caused activities close to the area. Also, the non-indigenous species should be studied for their potential to be invasive.

Seafood is one of the common causes of food allergies to adults. The sea hare Aplysia kurodai is a marine mollusk which belongs to invertebrate gastropod that has been consumed as a food in Korea. Cases of acute toxic hepatitis after ingestion of sea hares have been reported, but few cases of allergic reactions to sea hare have been reported in the literature. A 33-year-old man was referred to our Emergency Department due to urticaria and periorbital/perioral swelling after eating sea hares. Approximately 10 years ago, he experienced similar allergic reactions to it. Skin prick and intradermal tests showed strong positive responses to crude sea hare allergen extract. He was diagnosed with food allergy to sea hares. We herein report the first case of sea hare allergy after ingestion.

Seafood is a vehicle for the transmission of intoxication. The Neptunea are sublittoral species of the marine prosobranch mollusk. Tetramine toxin is found in the salivary gland of Neuptunea. A woman developed blurred vision, dizziness, headache, diarrhea, numbness and gait disturbance one hour after ingesting conchs. Neurological examination showed dysesthesia, and motor weakness. Laboratory and electrophysiological studies were normal. The next day, she recovered from her symptoms. We report a patient with dysesthesia and motor weakness due to Neuptunea species' tetramine toxin.

The purpose of this study was to investigate utilization and storage management practice of the frozen and refrigerated foods in school foodservice. 222 dietitians employed in school foodservice were surveyed. In school foodservice, the refrigerated stock farm products and seafoods (78.3%) were more used rather than frozen products (47.5%). According to school foodservice characteristics, the refrigerated meats including dairy products were more frequently used in elementary and middle schools than high school foodservice. On the other hand, the foodservice in high school used more frozen seafoods and processed foods than elementary school did. The data also showed a tendency for the contracted foodservice using more frozen meats and seafoods rather than refrigerated products when comparing with the self-operated foodservice. In terms of receiving conditions, storage methods and storage time, the result indicated that frozen or refrigerated products were often delivered at inappropriate temperature. Especially some products which were needed to be shipped and stored at refrigerated temperature such as mollusks, were delivered and kept at room temperature. The most frequently used thawing method were running water (56.9%), however, the frozen products were often sitted at room temperature for the purpose of thawing. According to the results, several inappropriate handling processes for frozen and refrigerated products were found in school foodservice. In order to improve handling process for frozen and refrigerated products, recognition of food handlers' weakness about storage and distribution, development of radical standards for receiving conditions, storage and thawing methods should be debated.

BACKGROUND: Molluscum contagiosum is a common viral skin infection seen mostly in children. A topical treatment modality for this condition is therefore desirable.
OBJECTIVE: To determine the efficacy of Imiquimod 5% cream in the treatment of molluscum contagiosum in Filipino children.
METHODS: Thirty Filipino children age 3 to 18 seen at the Philippine General Hospital outpatient dermatology clinic diagnosed with molluscum contagiosum were enrolled in this open label study. Imiquimod 5% cream was applied to each molluscum lesion and washed off after a contact time of 10 to 12 hours. Resolution of lesions and occurrence of systemic and local side effect were monitored.
RESULTS: Out of the twenty-four (80%) patients who completed the study, 5 (21%) had a less than or equal to 50% decrease in the number of lesions, 14 (58%) a greater than 50% decrease in the number of lesions, and 5 (21%) had complete resolution of all their mollusca. The target lesion resolved in 14 (58%) of the patients. No systemic side effect was observed. While mild to moderate erythema, pruritus, or erosion and mild pain and crusting were the only local side effects noted.
CONCLUSION: This study shows the possible effectiveness of Imiquimod 5% cream in the treatment of molluscum contagiosum in children. This topical medication has no systemic side effect and is well tolerated.

There is a limitation to estimate vitamin B12 intake due to a lack of data on vitamin B12 content in many Korean foods. In this study, vitamin B12 content was determined in some seaweeds, fish, and shellfish and their product that are consumed in Korea using a modified microbioassay with Lactobacillus delbruecki ATCC 7830. Dried laver and dried seasoned and toasted laver contained very high levels of vitamin B12 (66.8 and 55.2-71.3 microg/100 g, respectively. Sea lettuce and seaweed fulvescene also contained high vitamin B12 content of 5.47-9.41 and 6.46-7.20 microg/100 g, respectively, whereas sea mustard and sea tangle contained low levels of vitamin B12; vitamin B12 was not detected in seaweed fusifome. Pacific saury, trout, sea-bass, or squid contained 12.01, 2.00, 0.49 and 2.33 microg vitamin B12/100 g, respectively. Ochellatus octopus, and naked sand lance contained 0.72-1.43 and 3.68 microg vitamin B12/100 g, respectively. Dried Alaska pollack contained 0.19-2.64 microg vitamin B12/100 g. Shellfish such as little neck clam and small ark shellfish contained high levels of vitamin B12 of 30.5-40.5 microg/100 g, and mussel and abalone contained 17.71 and 7.82 microg/100 g, respectively. Of unique Korean traditional fermented seafood products, salt-fermented products of squid (2.91 microg/100 g), clams (34.31 microg/100 g), Alaska pollack roe (9.98-12.02 microg/100 g), hairtail guts (4.58 microg/100 g) or small shrimp (0.58-1.55 microg/100 g), and fish sauce from anchovies (1.52-1.78 microg/100 mL), sand eel (0.22-0.24 microg/100 mL) or small shrimp (0.19-0.78 microg/100 mL) were analyzed. A few commercial brands of flying fish roe (0.73-1.73 microg/100 g), canned tuna (0.40 microg/100 g), and fried fish paste (0.25-0.69 microg /100 g) were also analyzed. In conclusion, vitamin B12 content in these foods, chosen considering the Korean food culture, should contribute to improve the present vitamin B12 food database. It may be helpful to estimate vitamin B12 intake more correctly than before, and provide additional information for dietary education related to vitamin B12 and meal management.

OBJECTIVEThe aim of this survey was to investigate the level of contamination of the most consumed foods in China with 16 rare earth elements (REEs), and to provide the basic data for establishing and revising food safety standards for REEs.
METHODSSixteen REEs in foods were measured by inductively coupled plasma-mass spectrometry (ICP-MS) in the labs of the Centers for Disease Control and Prevention of four provinces and two municipalities, during 2009-2010.
RESULTS1 231 samples were analyzed and 19 121 concentration data of 16 REEs were collected. The REEs levels in the investigated foods varied significantly. The concentrations of cerium (Ce), dysprosium (Dy), yttrium (Y), lanthanum (La), and neodymium (Nd) were relatively high, while the remaining eleven REEs were at low levels. The mean values of total rare earth element oxides (REOs) in cereals, fresh vegetables, fresh aquatic products, fresh meats and eggs varied from 0.052 mg/kg to 0.337 mg/kg.
CONCLUSION16 REEs in the major foods were at very low contamination levels in the investigated regions.

The identification of five marine-derived shell traditional Chinese medicine (TCM) recorded in the Chinese Pharmacopoeia were studied. Using near infrared technology (NIR) combined with principal component analysis (PCA) methods, Ostreae Concha, Haliotidis Concha, and Margaritifera Concha could be efficiently distinguished from Meretricis Concha together with Arcae Concha. In the first principal components, Ostreae Concha exhibited obvious differences with high loadings in 4 236, 5 263, 7 142 cm(-1) concerning to the contents of CaCO3 and H2O in the samples. Arcae Concha and Meretricis Concha displayed significant differences with others in the second principal components, which can be illustrated by high loadings in 5 000 -4 430 cm(-1) areas. It is indicated that the second principal components might be related to organics which contained NH and CH groups, for example proteins. Meanwhile, our data showed a correlation between the function of these shell TCM and their distribution in the PCA plot. These results suggested that organic components in marine-derived shell TCM could not be neglected for their quality control.
