EFFECTS OF A SEASON OF SUBCONCUSSIVE CONTACT ON CHILD- SCAT3 SCORES IN 8-12 YEAR-OLD MALE ATHLETES.

Background: Each year, over 173,000 children and adolescents visit emergency departments due to sports and recreation related concussions, an increase of 60% over the last decade due to the rise in the number of children participating in sport. While numerous authors have sought to address the epidemiology of concussions across multiple age groups who participate in contact sports, a recent review of literature did not reveal a substantial amount of published articles that addressed the issue of subconcussive contact. Multiple tools have been developed to assess acute episodes of concussion.

Regional chemotherapy: overview.

Regional chemotherapy was developed in the 1950s and continues to play an integral part in the development of newer therapies for advanced solid malignancies. Regional therapies have evolved in complexity but are still based on the pharmacokinetics of drug delivery to solid malignancies. Newer techniques demonstrate that the combination of regional therapies, hyperthermia, and surgery is essential in promoting improved patient outcomes.

The benefits of inpatient diabetes care: improving quality of care and the bottom line.

Objective: To analyze the impact of a hospital-wide inpatient diabetes management program on quality of care, length of stay, and cost.

Methods: A retrospective review was conducted for diabetes identification and treatment in a large tertiary care hospital in Oklahoma City, Oklahoma. Cultural change was accomplished by educating the healthcare professionals and medical staff.

Intra-arterial chemotherapy for unresectable pancreatic cancer.

Background: A phase II trial of a new intra-arterial chemotherapy regimen for unresectable pancreatic cancer (UPC).

Patients And Methods: Ninety-six patients with UPC were treated with intra-arterial chemotherapy at three-weekly intervals. The schedule used was FLEC: 5-fluorouracil 1000 mg/m2, folinic acid 100 mg/m2, carboplatin 300 mg/m2; epirubicin 60 mg/m2.

Isolated hyperthermia chemotherapy perfusion for limb melanoma.

Safe techniques for regional chemotherapy of the limbs by perfusion are now available. The method is effective in obtaining regionally confined high levels of toxic drugs or chemotherapeutic agents in the isolated areas. The best responses have been observed in limb melanoma with recurrent or intransit disease.

Malignant melanoma in American black females: an unusual distribution of primary sites.

Background: Since the inception of the Charity Hospital Tumor Registry in 1948, 80 cases of malignant melanoma in blacks were treated at the Tulane University School of Medicine, Department of Surgery. Among black people, melanoma occurs on acral dermal sites. The histologic type is primarily acrallentiginous melanoma (ALM), found on acral, volar-subungual skin and junctional mucocutaneous sites.

Regional chemotherapy for inoperable pancreatic carcinoma.

Background: Survival for adenocarcinoma of the pancreatic remains unchanged over the last two decades. The majority of patients (85%) are diagnosed with an inoperable tumor. Patterns of failure reveal that pancreatic cancer involves three compartments: the pancreatic bed and regional lymph nodes, the liver and the peritoneal surfaces.

Regional chemotherapy with hemofiltration: a rationale for a different treatment approach to advanced pancreatic cancer.

Background/aims: Since 1989, thirty-two patients with advanced, intra-abdominal pancreatic cancer were treated with regional chemotherapy in combination with extracorporeal hemofiltration.

Patients And Methods: Eleven patients had locally advanced, unresectable cancer, and ten had advanced disease with liver metastases. Three patients had developed liver metastases following a radical resection.

Primary non-Hodgkin's lymphoma of the duodenum.

Primary non-Hodgkin's lymphoma of the duodenum is an uncommon primary tumor of the gastrointestinal (GI) tract. Diffuse, large cell lymphoma of B-cell origin is currently recognized as representing the predominant histologic type of primary extranodal lymphoma arising in a gastrointestinal site. Three patients are presented with primary lymphoma arising in the second (two) and fourth (one) portions of the duodenum.

Regional chemotherapy for melanoma. A 35-year experience.

Objective: The authors present their 35-year experience with intra-arterial chemotherapeutic regional perfusion of 1139 patients with melanomas, using an extracorporeal oxygenated circuit and heart-lung apparatus.

Summary Background Data: Intra-arterial chemotherapy produces improved responses in many tumors. By isolating and sustaining the area with extracorporeal oxygenated circulation, high doses can be delivered to the tumor area, limited only by local toxicity.

Study of the relative incidences of psychosocial factors before and after heart transplantation and the influence of posttransplantation psychosocial factors on heart transplantation outcome.

Psychosocial factors substance abuse, noncompliance, psychiatric problems, and obesity in relation to the outcome of heart transplantation have been investigated. Data were gathered at the time of initial assessment, and patients (n = 53) were monitored during the follow-up after heart transplantation (mean 18 months). Noncompliance, psychiatric problems, or excessive weight before heart transplantation continued after heart transplantation.

Multiple perfusions for melanoma.

From 1957 to 1992, 1139 patients had regional perfusion alone, or combined with excisional surgery for malignant melanoma. Of these, 158 patients had multiple perfusions for recurrent disease, including 155 for limb melanoma and three for head and neck melanoma. One-hundred-and-twenty patients were perfused twice, 28 treated three times, eight treated four times, and two treated five times.

Prognostic evaluation of intracranial metastasis in malignant melanoma.

Background: Malignant melanoma (MM) is often reported as the third most common cause of intracranial metastasis (IM) after carcinoma of the breast and lung. Most patients with advanced MM will have widespread extracranial disease, but the majority will die from intracerebral spread.

Methods: A retrospective review of 117 patients with documented IM from MM over the past 25 years was undertaken.

Acral lentiginous melanoma.

Between 1958 and 1990, 82 patients with acral lentiginous melanoma were treated by the Tulane Surgical Service with regional perfusion, excision of lesion, and lymph node dissection. The patient group comprised 27 white men, 29 white women, 18 black men, and 8 black women, with an average age of 61 years. More foot lesions than hand lesions were reported, and all the lack men had foot lesions.

Vaginal melanoma and the role of regional chemotherapy.

Vaginal melanoma is a rare cancer usually diagnosed as a locally advanced disease. Aggressive surgical management of the primary tumor and local-regional recurrences, combined with the use of adjuvant radiation and chemotherapy, improves disease-free interval and, perhaps, survival times. Techniques of regional chemotherapy allow the delivery of high doses of chemotherapy to the tumor bed, while minimizing systemic toxicities.

Prevention of loss of vertebral bone density in heart transplant patients.

Seventy-six patients (63 men, 13 women) have been followed up by vertebral bone density (VBD) studies from 3 to 36 months. VBD was measured by single-energy computerized tomographic scan. Before transplantation, VBD was found to be lower than in age-matched controls (less than 40 years of age [group 1], 96% of controls: 40 through 49 years of age [group 2], 77%; 50 to 60 years of age [group 3], 87%; more than 60 years of age [group 4], 76%).

Treatment of abdominal malignant neoplasms using regional chemotherapy with hemofiltration.

The regional delivery of high-dose chemotherapy for malignant neoplasms of the limb with the isolated regional perfusion technique was first described in the late 1950s. Recently, the use of concomitant hemofiltration for rapid systemic drug removal permits the use of higher regional drug levels in treating patients with advanced abdominal malignant neoplasms without complete vascular isolation. Twenty-five patients successfully underwent 42 treatments of high-dose intra-arterial chemotherapy with concomitant hemofiltration at Tulane University Medical Center Hospital, New Orleans, La, from 1989 through 1990.

Successful management of symptomatic cytomegalovirus disease with ganciclovir after heart transplantation.

In the 30-month period from January 1987 through June 1989, 57 patients underwent heart transplantation. Immunosuppressive therapy consisted of a combination of cyclosporine, azathioprine, low-dose methylprednisolone, and antilymphoblast globulin. Clinically significant, proven cytomegalovirus (CMV) disease has developed in no fewer than 22 patients (39%), involving the lung (n = 11), colon (n = 8), stomach (n = 4), and retina (n = 1).

Regional perfusion for the treatment of subungual melanoma.

Thirty-one patients with subungual melanoma representing 2.6 per cent of all patients with limb melanoma were treated by isolated regional perfusion. Acral lentiginous melanoma prevalent on subungual and volar skin was the most common histologic type.
