Abstract
BACKGROUND We aimed to study the prevalence of oral sex and its possible association with human papillomavirus (HPV) 16 infection in the development of oropharyngeal cancer in the US population for possible prevention. METHODS We conduct a systemic review on the prevalence of oral sex among Americans among different age groups, the prevalence of HPV 16 infection reported in oropharyngeal cancer, and correlation between oral sex and oropharyngeal cancer. RESULTS Oral sex is prevalent among adolescents and sexually active adults. Sixty percent of oropharyngeal cancer reported in the United States is associated with HPV 16 infections. Individuals who practiced oral sex with multiple partners are at risk for developing oropharyngeal cancer and need to be informed about practicing safe sex or getting vaccination. CONCLUSION Family physicians will play a key role in prevention and educating the public about the risk of oral sex.

Abstract
The results of skin biopsies over a 10 year period were reviewed from the outpatient dermatology clinic at the Brody School of Medicine in Greenville, North Carolina. This research was conducted because there are very few studies that characterize this information over a long-term horizon. The biopsy rate per patient encounter, the clinical reason for the biopsy, the biopsy outcomes, the distribution of cutaneous malignancies per encounter, and the distribution of the subtypes of basal cell carcinoma, squamous cell carcinoma, and melanoma were analyzed. Biopsy logs from January 1, 2001 to December 31, 2010 were reviewed. Our investigation found that 20% of patient encounters resulted in a biopsy. Of these biopsies, 87.9% were performed to rule out malignancy and 12.1% were completed on patients suspected of having inflammatory skin conditions. The basal cell carcinomas diagnosed in Greenville, NC have more aggressive histologic subtypes compared to other studies, whereas the squamous cell carcinomas and melanomas were less aggressive.

Abstract
Traditionally, faculty assessment of preclinical crown preparations occurs by visualizing preparation features. However, contemporary CAD/CAM tools have the ability to more precisely evaluate preparation features, which is beneficial for psychomotor development. Taper is one of the most challenging features to objectively assess. The aim of this study was twofold: first, to validate the software's ability to distinguish differences in taper, and second, to compare traditional faculty assessment with digital assessment of taper. In the study, 30 all-metal crown preparations were created on typodont teeth with varying degrees of axial reduction and placed into three groups based on amount of taper (minimum, moderate, or excessive). Each tooth was scanned with the D4D scanner, and the taper was analyzed using E4D Compare. A second experiment used 50 crown preparations of tooth #19, which were done as a formative exercise. A comparison faculty assessment with CAD/CAM assessments of taper was performed. The results showed that when the taper was varied, E4D Compare was able to distinguish those differences; the Tukey post-hoc test revealed a significant difference (p=0.001). The qualitative analysis comparing faculty grading to CAD/CAM grading demonstrated a trend for CAD/CAM to be more precise. These results suggest that E4D Compare is an effective means of quantitatively measuring the amount of total occlusal convergence or taper on a crown preparation and that digital assessment may be more precise than faculty visual grading.

Abstract
OBJECTIVE Hypertensive disorders in pregnancy remain a major cause of maternal morbidity and mortality. Blood pressure control is essential for maternal and neonatal outcome. Therefore, we analyzed the potency and side effects of two treatment options (nicardipine compared to labetalol) in order to gain insight in improved treatment of severe hypertension during pregnancy and to evaluate the feasibility of a randomised controlled trial. STUDY DESIGN A nested case control study in an inner city teaching hospital alongside a meta-analysis. Data from women who received nicardipine were compared with patients who received labetalol during pregnancy. Primary outcome measure was successful control of severe hypertension. Secondary outcome measures were maternal and neonatal side effects. These results were included in a meta-analysis. RESULTS Only one previous study described nicardipine in comparison to labetalol during pregnancy. The combined results indicate a similar success-rate of treatment with nicardipine compared to labetalol during pregnancy. Women treated with nicardipine had more often tachycardia, headache and nausea compared to women treated with labetalol. Hypotension resulting in fetal distress was found more often in the labetalol group. CONCLUSION Nicardipine is a potent drug to control hypertension during pregnancy with side effects including maternal headaches, nausea and tachycardia. Labetalol had more neonatal side effects including hypotension compared with nicardipine. These results support the justification and prove that it is safe to perform a randomized controlled trial comparing nicardipine to labetalol in the treatment of severe hypertension in pregnancy.

Abstract
BACKGROUND The majority of cancer patients loses weight and becomes malnourished during the course of their disease. Metabolic alterations and reduced immune competence lead to wasting and an increased risk of infectious complications. In the present study, the effect of a nutritionally complete medical food, which is high in protein and leucine and enriched with fish oil and specific oligosaccharides, was investigated on immune function, nutritional status, and inflammation in patients with esophageal cancer and compared with routine care. METHODS In this exploratory double-blind study, 64 newly diagnosed esophageal cancer patients were randomized. All patients received dietary counselling and dietary advice. In the Active group, all patients received the specific medical food for 4 weeks before the start of anticancer therapy. In the routine care control arm, patients with <5% weight loss received a non-caloric placebo product, and patients with weight loss ≥5% received an iso-caloric control product to secure blinding of the study. The required study parameters of body weight and performance status were recorded at baseline and after 4 weeks of nutritional intervention, and patients were asked to complete quality of life questionnaires. In addition, blood samples were taken for the measurement of several immune, nutritional, and safety-parameters. RESULTS No effect of the specific nutritional intervention could be detected on ex vivo stimulations of blood mononuclear cells. By contrast, body weight was significantly increased (P < 0.05) and ECOG performance status was improved after intervention with the specific medical food (P < 0.05). In addition, serum Prostaglandin E2 (PGE2) levels were significantly decreased in the specific medical food group and increased in the control group (P = 0.002). CONCLUSIONS Nutritional intervention with the specific medical food significantly increased body weight and improved performance status compared with routine care in newly diagnosed esophageal cancer patients. This effect was accompanied by significantly reduced serum PGE2 levels.

Abstract
A retrospective review of 32 patients with stage III nonsmall cell lung cancer who underwent chemoradiation with image-guided radiotherapy (IGRT) was recorded. Acute grade 3-4 hematologic and esophageal toxicities developed in 6 and 13 patients respectively. At a median follow-up of 14.5 months, only one patient developed grade 3 pneumonitis. The median survival was estimated to be 17 months. Five patients (15%) developed loco-regional recurrences, and 17 patients (53%) distant metastases. Grade 3-4 toxicities remained significant during chemoradiation with IGRT. However, the reduced rate of severe pneumonitis despite a high tumor dose is encouraging and needs to be investigated in future prospective studies.

Abstract
BACKGROUND Few studies examined joint attention in interactions with people with profound intellectual and multiple disabilities (PIMD), although being an important component of high-quality interaction. The purpose of this study is to describe initiating joint attention behaviour from people with PIMD and their support workers as well as the sequential relationship between initiating joint attention behaviour and attention episodes in spontaneous interactions. METHOD Video observations of 28 support worker-client dyads were coded using partial interval coding. RESULTS Results show much variation across persons and dyads. Within the support worker-client dyad, there is not much joint attention but shared attention is frequently occurring. In general, people with PIMD are directing the attention of their interaction partner at low rates. The support workers are frequently directing the attention of the clients towards a topic of interest but not often through the tactile modality. The occurrence of an attention episode cannot be predicted on the basis of preceding initiating joint attention behaviour of the interaction partners. CONCLUSION This study presents directions for future research and implications for practice. It may increase support workers' knowledge of their own contributions, strengths and weaknesses in directing and maintaining attention within interactions with people with PIMD.

Abstract
While some probiotics have shown beneficial effects on preventing or treating colitis development, others have shown no effects. In this study, we have assessed the immunomodulating effects of two probiotic strains, Lactobacillus rhamnosus (L. rhamnosus) and Bifidobacterium breve (B. breve) on T cell polarization in vitro, using human peripheral blood mononuclear cells (PBMC), and in vivo, using murine dextran sodium sulfate (DSS) colitis model. With respect to the latter, the mRNA expression of T cell subset-associated transcription factors and cytokines in the colon was measured and the T helper type (Th) 17 and regulatory T cell (Treg) subsets were determined in the Peyer's patches. Both L. rhamnosus and B. breve incubations in vitro reduced Th17 and increased Th2 cell subsets in human PBMCs. In addition, B. breve incubation was also able to reduce Th1 and increase Treg cell subsets in contrast to L. rhamnosus. In vivo intervention with B. breve, but not L. rhamnosus, significantly attenuated the severity of DSS-induced colitis. In DSS-treated C57BL/6 mice, intervention with B. breve increased the expression of mRNA encoding for Th2- and Treg-associated cytokines in the distal colon. In addition, intervention with B. breve led to increases of Treg and decreases of Th17 cell subsets in Peyer's patches of DSS-treated mice. B. breve modulates T cell polarization towards Th2 and Treg cell-associated responses in vitro and in vivo. In vivo B. breve intervention ameliorates DSS-induced colitis symptoms and this protective effect may mediated by its effects on the T-cell composition.

Abstract
We present a case study of a 10-year-old child with severe burns that were misinterpreted as inflicted burns. Because of multiple injuries since early life, the family was under suspicion of child abuse and therefore under supervision of the Child Care Board for 2 years before the boy was burned. Because the boy incurred the burns without feeling pain, we conducted a thorough medical examination and laboratory testing, evaluated detection and pain thresholds, and used MRI to study brain morphology and brain activation patterns during pain between this patient and 3 healthy age- and gender-matched controls. We found elevated detection and pain thresholds and lower brain activation during pain in the patient compared with the healthy controls and reference values. The patient received the diagnosis of hereditary sensory and autonomic neuropathy type IV on the basis of clinical findings and the laboratory testing, complemented with the altered pain and detection thresholds and MRI findings. Hereditary sensory and autonomic neuropathy IV is a very rare congenital pain insensitivity syndrome characterized by the absence of pain and temperature sensation combined with oral mutilation due to unawareness, fractures, and anhidrosis caused by abnormalities in the peripheral nerves. Health care workers should be aware of the potential presence of this disease to prevent false accusations of child abuse.

Abstract
BACKGROUND In this study the feasibility of intensity-modulated radiotherapy (IMRT) and tomotherapy-based image-guided radiotherapy (IGRT) for locally advanced esophageal cancer was assessed. METHODS A retrospective study of ten patients with locally advanced esophageal cancer who underwent concurrent chemotherapy with IMRT (1) and IGRT (9) was conducted. The gross tumor volume was treated to a median dose of 70 Gy (62.4-75 Gy). RESULTS At a median follow-up of 14 months (1-39 months), three patients developed local failures, six patients developed distant metastases, and complications occurred in two patients (1 tracheoesophageal fistula, 1 esophageal stricture requiring repeated dilatations). No patients developed grade 3-4 pneumonitis or cardiac complications. CONCLUSIONS IMRT and IGRT may be effective for the treatment of locally advanced esophageal cancer with acceptable complications.

Abstract
BACKGROUND Immersion treatment (IT) provided in a camp setting has been shown to promote short-term improvements in weight and health status in obese adolescents. However, evidence of IT's long-term efficacy and efficacy for multi-ethnic and lower socioeconomic status (SES) adolescents is limited. METHODS This was a cohort study with a pre/post design and longitudinal follow-up. The intervention was a 19-day camp-based IT program comprising (1) a nutrition curriculum and ad-lib access to a nutritious diet, (2) several hours of physical activity daily, (3) group therapy, and (4) cognitive-behavioral therapy (CBT). This analysis included 52 low-SES adolescents that participated in 2009 and 2010. A subgroup of 33 campers and their families was offered follow-up monthly for 10 months. Primary outcome measures were change in weight-related parameters immediately postcamp and after 10 months of follow-up. RESULTS Campers had significant short-term improvements in mean waist circumference (mean [M], 2.6; standard deviation [SD], 3.2 cm), weight (M, 2.6; SD, 1.9 kg), BMI (M, 1.1; SD, 0.9 kg/m2), BMI z-score (M, 0.06; SD, 0.07), and percent overweight (M, 6.1; SD, 4.7). Campers offered follow-up had a modest increase in mean percent overweight (M, 2.0; SD, 8.4) during 10 months of follow-up. However, 33% experienced continuing decline in percent overweight during follow-up, and long-term follow-up was associated with significant overall (precamp vs. end of follow-up) improvements in percent overweight (M, 4.9; SD, 7.2). CONCLUSIONS Camp-based IT with CBT is a promising intervention for improving short- and long-term weight status of low-SES adolescents. Additional research is needed to increase long-term efficacy.

Abstract
Background: To assess the tolerance of patients with small cell lung cancer undergoing chemoradiation with tomotherapy-based image-guided radiotherapy (IGRT). Materials and Methods: A retrospective review of the toxicity profile for nine patients with small cell lung cancer of the limited stage who underwent chemoradiation delivered with helical tomotherapy (HT) has been conducted. Results: Acute grade 3–4 hematologic and esophagitis toxicities developed in two and three patients respectively. One patient developed a pulmonary embolism during radiotherapy. Seven patients had weight loss ranging from 0 to 30 pounds (median: 4 pounds). Three patients had treatment breaks ranging from 2 to 12 days. At a median follow-up of 11 months (range: 2–24 months), no patients developed any radiation related toxicities such as grade 3–4 pneumonitis or other long-term complications. The median survival was estimated to be 15 months. There were two local recurrences, three mediastinal recurrences, and six distant metastases. Conclusion: Grade 3–4 toxicities remained significant during chemoradiation when radiation was delivered with tomotherapy-based IGRT. However, the absence of grade 3–4 pneumonitis is promising and the use of HT needs to be investigated in future prospective studies.

Abstract
OBJECTIVE To determine how the implementation of a methicillin-resistant Staphylococcus aureus (MRSA) control program in an inpatient rehabilitation facility (IRF) affects MRSA health care-associated infections (MRSA-HAIs). DESIGN A retrospective chart review. SETTING IRF affiliated with Vidant Medical Center, an 861-bed, acute-care teaching hospital for The Brody School of Medicine at East Carolina University. PATIENTS Seventy-nine adult patients in the IRF who developed a MRSA-HAI from February 2005 through January 2011. INTERVENTIONS Both the acute care hospital and the affiliated inpatient rehabilitation unit began screening 100% of admissions for MRSA nasal carriage, with decolonization of positive carriers, starting in February 2007. MAIN OUTCOME MEASUREMENTS Yearly rates of MRSA-HAI per 1000 patient-days were compared in the IRF before and after the intervention. RESULTS The weighted mean monthly infection rate before the intervention (February 2005 through January 2007) was 1.0714 per 1000 patient days compared with 0.6557 per 1000 patient days after the intervention (February 2007 through January 2011). The decreased infection rates after the intervention were statistically significant (P = .0315). CONCLUSIONS The implementation of an all-admissions MRSA screening program with decolonization of positive carriers in an IRF affiliated with an acute care hospital resulted in decreased MRSA-HAI rates in the IRF. When developing surveillance guidelines for MRSA, IRFs should be cognizant of infection rate trends and of the affiliated hospital's scope of policies and practices for infection prevention and control.

Abstract
BACKGROUND Behavioural observations are the most frequently used source of information about emotions of people with severe or profound intellectual disabilities but have not yet been validated against other measures of emotion. In this study we wanted to validate the behavioural observations of emotions using respiration (rib cage contribution, total breath duration, inspiratory time, expiratory time, tidal volume, mean inspiratory flow, minute ventilation) and heart rate variability. METHOD Twenty-seven participants were presented with four negative and four positive stimuli. During the presentation the participants' respiration and heart rate variability was measured. Each behaviour of the participant was coded as emotive or not. RESULTS We found the hypothesised higher percentage rib cage contribution, marginal lower mean inspiratory flow and lower heart rate variability when the expressed emotions became more positive. CONCLUSIONS These results validate the use of behavioural observations to make inferences about emotions.
