A review of the risks and relationships between oral health and chronic diseases.

Advances in medical science and in preventive dentistry have changed the context of oral health. The American population is living longer with numerous complex chronic diseases. This paper is to raise awareness about the impact of multiple chronic diseases and their associations with oral diseases. Comorbidities can worsen the course of dental treatment. Inflammation has been the connecting factor in the bidirectional pattern of oral and systemic diseases. High occurrences of chronic diseases generally occur in aging as well as disadvantaged populations. Serious infections, slow healing, prolonged bleeding, and hospitalizations can escalate in patients with uncontrolled chronic diseases. A multidisciplinary team-based approach to patient management can minimize complications and unexpected challenges.

Sickle cell disease: Contributing factors and radiological assessments.

Sickle Cell Disease (SCD) is genetically described as an autosomal blood disorder resulting from the presence of a mutated form of hemoglobin. Morbidity, frequency of crisis, degree of anemia, and organ systems involved vary considerably per patient. Dental health professionals and other specialists commonly request comprehensive medical consultations prior to performing complex periodontal, endodontic, and surgical procedures. In order to have successful dental outcomes and minimize posttreatment dental complications, relevant disease indicators are noted. This review is to raise awareness of the impact of oral diseases in patients with sickle cell disease and to emphasize the importance of full medical disclosure, radiographic interpretation, and a well-documented medical history, and a well-written consultation which can guide treatment planning and greatly improve the course of dental treatment.

Strut-adjusted volume implant (SAVI) brachytherapy-based accelerated partial breast irradiation (APBI) in African American women.

PURPOSE: To examine the clinical outcomes of postmenopausal African American (AA) women treated with strut-adjusted volume implant brachytherapy-based accelerated partial breast irradiation for early-stage node-negative breast cancer. METHODS: From January 2011 through April 2015, a total of 50 AA patients, meeting criteria to receive APBI as defined by the National Surgical Adjuvant Breast and Bowel Project B-39 (NASBP B-39), completed treatment with the SAVI breast brachytherapy device at Howard University Hospital. RESULTS: 4% ipsilateral breast tumor recurrence and 2% breast cancer-specific mortality was observed. Median follow-up has been 3.8 years with a range of 0.29-4.69 years. Dosimetry parameters yielded a median V90 of 96.22% (range 77.86-105.00%), a median V150 of 31.27 cm3 (range 23.30-49.15 mL), and a median V200 of 14.53 cm3 (range 5.92-19.38 mL). Cosmesis was excellent. There were no infections, persistent seromas, fat necrosis, or telangiectasias observed to date. CONCLUSIONS: This study is the first study to describe the use of SAVI as APBI in an exclusively AA population. This study has demonstrated excellent local control in appropriately selected patients, similar clinical outcomes to the general population, and good to excellent cosmesis in AA women to date.

Relationship Between Aerobic Fitness, the Serum IGF-1 Profiles of Healthy Young Adult African American Males, and Growth of Prostate Cancer Cells.

The growth of prostate tumors is mediated by the bioavailability of androgens and insulin-like growth factors. This study tested the hypothesis that healthy young adult African American men exhibiting low aerobic capacity (fitness) have serum insulin-like growth Factor-1 (IGF-1) and testosterone levels that promote growth of prostate cancer cells. A cross-sectional data research design was used to study groups of 18- to 26-year-old healthy men exhibiting low and moderate aerobic fitness, based on their peak oxygen consumption (VO2peak). The individual serum levels of IGF-1, IGF-1 binding protein-3 (IGFBP-3), and testosterone were measured. In vitro growth of androgen-dependent LNCaP prostate tumor cells was measured after incubation in culture medium fortified with each subject's serum. Aerobic capacity was significantly greater in the moderate-fitness group than in the low-fitness group without an intergroup difference in body mass index. The serum IGF-1 concentration was significantly higher in the low-fitness group in the absence of an intergroup difference in serum testosterone. The serum IGFBP-3 concentration was significantly lower in the low-fitness group. Prostate tumor cell growth was significantly greater in the cultures incubated in media containing the sera of the low-fitness group than in the sera of the moderate-fitness group. These findings suggest that moderate aerobic fitness in young adults may decrease the circulating levels of free IGF-1 and lower the potential to support growth of prostate cancer cells.

Radiation therapy in the last month of life.

AIM: We sought to survey a large, multi-center patient sample to better characterize/quantify RT utilization at the end of life. BACKGROUND: Few objective data exist for radiation therapy (RT) delivery at end of life (EOL). MATERIALS AND METHODS: Data were retrieved for all patients receiving RT in calendar year 2010 in the Department of Radiation Oncology at Indiana University (IU) and Howard University (HU) hospitals. Specific attention was made of the group of patients receiving RT in the last 30 days of life. RESULTS: A total of 852 patients received all or part of their RT during 2010 (HU: 139, IU: 713). At time of analysis in early 2012, 179 patients had died (21%). Fifty-four patients (6.3% of total; 30% of expired patients) died within 30 days of receiving their last treatment. Twenty patients (2.3% of total; 11.2% of expired patients) received RT within their last week of life. For both sites, the median time until death from completion of therapy was 12.5 days (range 2-30 days). CONCLUSIONS: Radiation in the last month of life is likely to provide minimal palliation or survival benefit. This, coupled with the financial implications, time investment, and physical costs, suggests that physicians and patients should more strongly consider hospice, and minimize duration of palliative RT courses as far as possible. As with chemotherapy, RT utilization at EOL should be considered for collection as an overuse metric.

A novel use of early radiation therapy in the treatment of hyperbilirubinemia in a patient with primary hepatic lymphoma and chronic hepatitis C.

Lymphomas arising in the liver are extremely rare. Here, we describe a case of Hepatitis C virus infection with primary hepatic lymphoma (PHL) presenting with hyperbilirubinemia. A 45-year-old African American male presented with abdominal pain, pruritus, and itching for two days. CT of abdomen and pelvis with contrast showed numerous masses in the liver. The liver biopsy was consistent with diffuse large B cell lymphoma (DLBCL). Conventional chemotherapy was avoided initially because of hyperbilirubinemia. Hence, radiation therapy was given initially to reduce his bilirubin levels and tumor size. The patient was able to complete six cycles of rituximab combined with cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) chemotherapy and achieved a complete response verified by positron emission tomography-computed tomography (PET-CT). PHL should be considered when there are numerous space occupying liver lesions seen on imaging. Hyperbilirubinemia may be a reason for delay in treatment for some of these patients. Hence, the role of radiation therapy prior to treatment with R-CHOP is an alternative to management for stage IV diffuse large B cell lymphoma.
