Abstract
BACKGROUND, AIM, AND SCOPE The aim of the present study was to evaluate the distribution of petroleum hydrocarbons in ten commercial fish species and water samples in three estuaries along Tamilnadu coast, Bay of Bengal, India. MATERIALS AND METHODS Fish and water samples collected from Tamilnadu coast, India, were extracted and analyzed for petroleum hydrocarbons by ultraviolet fluorescence (UVF) spectroscopy. RESULTS The petroleum hydrocarbon concentration (PHC) in coastal waters and fish species varied between 2.28 and 14.02 μg/l and 0.52 and 2.05 μg/g, respectively. The highest PHC concentration was obtained in Uppanar estuarine waters (14.02 ± 0.83) and the lowest was observed in Vellar estuarine waters (2.28 ± 0.25). DISCUSSION Among the ten fish species, Sardinella longiceps have high PHC concentration from all the locations. This study suggests that S. longiceps can be used as a good biological indicator for petroleum hydrocarbon pollution in water. CONCLUSIONS The concentration of petroleum hydrocarbons in coastal waters along Tamilnadu coast is markedly higher than that in the background, but there is no evidence for its increase in fish of this region. From a public health point, petroleum hydrocarbon residue levels in all fish samples analyzed in this study are considerably lower than the hazardous levels. RECOMMENDATIONS AND PERSPECTIVES At present, as Tamilnadu coastal area is in a rapid development stage of new harbour, chemical industries, power plants, oil exploration and other large-scale industries, further assessment of petroleum hydrocarbons and the various hydrodynamic conditions acting in the region are to be studied in detail and continuous pollution monitoring studies should be conducted for improving the aquatic environment. The results will also be useful for pollution monitoring program along the coastal region and also to check the levels of petroleum hydrocarbons.

Abstract
OBJECTIVE To determine the prevalence of traumatic dental injuries to primary incisors in 3-5 year-old preschool children and to study the relationship between dental injuries and age, gender and terminal plane relation. BASIC RESEARCH DESIGN A cross-sectional study was conducted in 1,126 preschool children aged three to five years enrolled in eleven private and public nursery schools, randomly selected in Chennai, India. METHOD Data regarding the age, gender, cause and type of trauma and terminal plane relation were recorded. Maxillary and mandibular primary incisors were examined for traumatic injuries and were recorded according to the method described by Andreasen & Andreasen (1994). Data were analyzed through descriptive analysis and chi-square test. RESULTS Traumatic injuries to primary incisors were identified in 6.2% of children. No significant gender differences in prevalence were seen (p > 0.05). Enamel fractures (57.3%) dominated amongst the type of injuries. Majority of children who sustained traumatic dental injuries to their primary incisors were associated with mesial step molar relation. CONCLUSION Mesial step molar relation may be considered one of the possible predisposing factors to trauma in primary dentition. Further, there is need to intensify oral health education targeted at both parents and teachers at nursery schools to inform them about consequences of primary teeth injuries on permanent dentition and emphasize the importance of prevention of dental injuries in children.

Abstract
About 15 % of war injuries involve the chest. Fortunately 85% of patients sustaining chest injuries that reach medical facility will require clinical observation or a simple procedure like tube thoracostomy. Only one in six patients has life-threatening injuries that necessitate urgent operative repair. Early deaths are caused by airway obstruction, major respiratory problems such as tension pneumothorax or massive hemothorax, and cardiac tamponade. These conditions are easily managed if recognized promptly. Diagnosis and management of various components of chest injury requires clear judgment and indepth knowledge of pathophysiological mechanisms involved. The therapeutic goal in the war scenario is to restore normal physiology and thereby to restore cardiac and pulmonary function and evacuate the patient after stabilization.

Abstract
BACKGROUND/OBJECTIVE beta-Carotene is often used as a marker for the amount of fruit and vegetables consumed, but little is known about plasma beta-carotene concentrations in subjects whose habitual (long-term) diets are characterized by different amounts of foods of plant origin. We compared dietary beta-carotene intake and plasma concentrations in women on habitual diets differing in the consumed amounts of foods of plant origin. METHODS A comparison of dietary beta-carotene intakes and plasma beta-carotene concentrations in women adhering to an average Western diet (n = 172), wholesome nutrition (following preventive recommendations) (n = 238) or a raw food diet (n = 104). RESULTS Dietary beta-carotene intake was 5.5, 9.3, 14.7 mg/day for women adhering to an average Western diet, wholesome nutrition and raw food diet, respectively (p < 0.001). Corresponding multivariate adjusted plasma beta-carotene concentrations were 1.07, 1.65, and 1.16 micromol/l, respectively (p < 0.001). Comparable dietary beta-carotene intake resulted in lower multivariate adjusted plasma beta-carotene in women adhering to a raw food diet and average Western diet compared to those on wholesome nutrition (p < 0.001 for all intake groups up to 20 mg/day). The amount of fruit and vegetable intake did not predict plasma beta-carotene levels in women consuming a raw food diet. CONCLUSIONS Plasma beta-carotene concentrations differed among the diet groups, with highest plasma levels in women adhering to wholesome nutrition. Plasma beta-carotene concentrations may not reflect beta-carotene intake and the amount of fruit and vegetables consumed.

Abstract
The scanning electron microscopy-energy dispersive spectroscopic (SEM-EDS) study of selected samples from an ice core collected from Central Dronning Maud Land (CDML), East Antarctica, revealed several microparticles. They are mainly siliceous and carbonaceous particles and have distinct variations in their shape and composition. The morphology and major element chemistry of the particles suggest their origin from either volcanic eruptions or continental dust. The EDS analysis revealed that the volcanic particles are enriched in silica (average SiO2 62%), compared to the continental dust particle (average SiO2 56%). We found that the tephra relating to Agung (1963) and Karkatau (1883) volcanic eruptions, as recorded, in the ice core harbored microbial cells (both coocoid and rods). The occurrence of organic and inorganic particles which bear relation to volcanic eruption and continental dust implies significant environmental changes in the recent past.

Abstract
BACKGROUND AND PURPOSE CT angiography (CTA) is widely used and may be the only vascular imaging technique ordered for emergent evaluation of neurovascular disease. With thin-section multisection CTA, the resolution of vessel wall imaging has improved. We describe cases of acute vertebral artery dissection (VAD) in which the only abnormality on CTA was a characteristic thickening of the wall of the V3 portion of the vertebral artery (VA). The arterial lumen at the dissection site was normal in caliber. This type of dissection is easily overlooked if only lumen-opacifying studies such as contrast MR angiography (MRA) or conventional angiography are performed. We highlight the importance of recognizing this finding, the "suboccipital rind" sign, in the V3 portion, a segment commonly affected in VAD. The purpose of our study was to review the CTA imaging characteristics of patients with VAD in the V3 portion compared with normal controls. MATERIALS AND METHODS Our imaging data base was reviewed for cases of acute VAD and the presence of a "suboccipital rind" sign. A control group of 50 patients was randomly recruited from a group of patients undergoing CTA. The VA luminal diameter, the wall thickness (total diameter-luminal diameter), and the ratio of luminal diameter/total diameter were measured along 5 adjacent V3 segments and were compared between the 2 groups. RESULTS There was no evidence of luminal tapering or narrowing in the dissected VAs compared with controls (P = .1). The average wall thickness of the dissection group was 2.96 mm greater than that for the control group (P < .001; 95% confidence interval, 2.6-3.3). There was a significant difference in the ratio of lumen diameter/lumen+wall diameter in dissected segments compared with controls (P < .001). CONCLUSIONS Cross-sectional vascular imaging is often performed with multisection helical CTA for a variety of concerns, some without neurologic symptoms. Our study confirms that in cases of the "suboccipital rind" sign, the lumen appears normal in caliber, with wall thickening as the only imaging sign of VAD. In our center, this clinically occult VAD would influence management, with patients usually treated with antiplatelet agents. We caution against using only luminal-opacifying techniques such as contrast-enhanced MRA or conventional angiography to exclude VAD because they are limited in the evaluation of mural hematoma.
