Nutrition and oral health in children with recently and previously diagnosed celiac disease.

OBJECTIVES: To evaluate the nutritional and oral health status of children with previously diagnosed celiac disease (CD) who follow a gluten-free diet and recently diagnosed CD patients. MATERIALS AND METHODS: Previously and recently diagnosed groups were formed from children with CD, aged 4 to 15 years. A questionnaire was completed about the children's dental history and nutritional and oral hygiene habits. All the children underwent an oral examination, and dmft-DMFT indices were determined. Dental plaque status, periodontal health, and dental enamel defects were recorded. Oral soft tissues were examined for the presence of lesions. Unstimulated salivary flow rate and pH value were evaluated. RESULTS: A statistically significant difference was determined between the previously and recently diagnosed patients in terms of toothpaste preference (p=0.003), frequency of going to the dentist (p=0.039), and the types of dental treatment they had received (p=0.001). A statistically significant difference was determined between the previously and recently diagnosed patient groups in terms of dmft values (p=0.005). CONCLUSIONS: Children with CD should be directed to a pediatric dentist to improve oral and dental health, relieve the symptoms of oral mucosal lesions, be informed about enamel defects, and be encouraged to use gluten-free oral care products. CLINICAL RELEVANCE: The collaboration of pediatric gastroenterologists and pediatric dentists can prevent the progression of oral symptoms in children with CD and eliminate long-term complications in terms of both oral health and multisystemic problems.

Survey of viral haemorrhagic septicaemia virus in wild fishes in the southeastern Black Sea.

Species diversity in the Black Sea ecosystem has been declining rapidly over the last 2 decades. To assess the occurrence and distribution of viral haemorrhagic septicaemia virus (VHSV) in various wild fish species, a wild marine fish survey was carried out in 2009, 2010, and 2011. The pooled or individual samples of kidney, liver, and spleen of 5025 specimens, belonging to 17 fish species, were examined virologically using cell culture. The cells showing cytopathic effects (CPE) were subjected to ELISA and multiplex reverse transcriptase polymerase chain reaction (RT-mPCR), for VHSV and infectious pancreatic necrosis virus (IPNV), after blind passaging to determine the virus species causing CPE. The virus species and possibility of co-infection with IPNV were verified by the RT-mPCR developed in this study. Twelve species of fish (pontic shad Alosa immaculata, red mullet Mullus barbatus, three-bearded rockling Gaidropsarus vulgaris, black scorpionfish Scorpaena porcus, Mediterranean horse mackerel Trachurus mediterraneus, whiting Merlangius merlangus euxinus, stargazer Uranoscopus scaber, pilchard Sardina pilchardus, garfish Belone belone, round goby Neogobius melanostomus, thornback ray Raja clavata, and anchovy Engraulis encrasicolus) tested positive for VHSV Genotype Ie (VHSV-Ie). Except whiting, pilchard, and round goby, the rest are new host records for VHSV. The extent and spread of VHSV-Ie was significantly higher among bottom fish than among pelagic fish. Sensitivity and specificity of the RT-mPCR developed was sufficiently high, suggesting that this assay may be used for both diagnostic and surveillance testing. According to the RT-mPCR results, IPNV was not present in wild fish. These results support the hypothesis that the VHSV-Ie genotype, highly prevalent among fish species in the Black Sea, may have a serious impact on the population dynamics of wild fish stocks.

Viral surveillance of cultured Rainbow Trout in the eastern Black Sea, Turkey.

To study the presence and spread of viral fish pathogens in Rainbow Trout Oncorhynchus mykiss in the eastern Black Sea region of Turkey, 172 pooled samples (seven fish per pool) of Rainbow Trout fry from 28 hatcheries were examined from December 2006 to July 2007. Forty-three pools (seven broodfish per pool) of seminal and ovarian fluids from 182 female and 119 male brood Rainbow Trout were also sampled during spawning. Moreover, reproductive fluids (22 pools) of wild trout (Salmo trutta labrax, S. t. caspius, S. t. abanticus, and S. t. macrostigma), captured by electroshocking in the rivers in and around the region, were sampled. Triplicate groups of 40 or 80 Rainbow Trout fry was also challenged with two similar isolates to determine their virulence on trout fry. Enzyme-linked immunosorbent assay was performed on the samples producing cytopathic effect on CHSE-214 cells. The positive results were confirmed with a reverse transcriptase polymerase chain reaction assay. Neither infectious hematopoietic necrosis virus (IHNV) nor viral hemorrhagic septicemia virus (VHSV) was detected during the survey. Of the 28 hatcheries sampled in the Black Sea region, 15 from six provinces tested positive for infectious pancreatic necrosis virus (IPNV) in trout fry. Unexpectedly, all reproductive fluids from both male and female cultured and wild broodstock tested negative for IPNV. Nucleotide sequences of the VP2/NS region of IPNV showed that all isolates collected (n = 38) in the region and surrounding areas belonged to the genogroup III. The findings strongly suggest that IPNV is endemic in the fry of farmed Rainbow Trout within the region. Virus prevention measures should be taken to prevent in-farm spread of these highly contagious, low-virulence isolates.

Monthly occurrence and prevalence of viral haemorrhagic septicaemia virus (VHSV) in whiting Merlangius merlangus.

A field survey was carried out to determine the occurrence and spread of viral haemorrhagic septicaemia virus (VHSV) in whiting Merlangius merlangus (L.), a key prey species in the southeastern Black Sea region. In March, April, September and December 2007 and monthly in 2008, 70 to 105 M. merlangus captured by gill nets were examined in pools of 7 fish per pool (total number of fish = 1603). After determining the seasonal occurrence of VHSV in whiting, 43, 80 and 88 whiting were sampled individually in January, February and March 2009, respectively, to determine age and size of whiting commonly infected with VHSV. The samples were tested in duplicate using BF-2 and EPC cell lines for virus isolation. Positive cultures (those demonstrating cytopathic effect, [CPE]), were tested further with a commercial ELISA kit to confirm that the observed CPE was caused by VHSV. VHSV was detected in M. merlangus only between February and April following a drop in the surface water temperature to 9 degrees C. All infected fish from the sampled whiting were asymptomatic carriers with low levels of virus. The estimated prevalence from pooled samples ranged between 1.35% (2.5 to 97.5 percentiles; 0.04 to 7.32%) to 3.14% (0.36 to 10.95%), whereas prevalence estimated from individual sampling was 7, 5 and 1% in January, February and March, respectively. Individual sampling also revealed that prevalence was higher among young fish (1 to 1.5 yr old) and decreased with increasing age. This is the first report of VHSV infection in whiting in the Black Sea.
