Epithelioid sarcoma of the hand

Twenty-eight patients were treated for a primary epithelioid sarcoma of the hand. Twenty-seven patients (96%) had excisions before evaluation, including 11 (39%) with multiple prior excisions with varying diagnoses before epithelioid sarcoma, and all had surgical treatment after referral. The patients' surgical management included three patients with amputation at the forearm, three patients with wide excision, and 21 patients with a partial amputation of the hand. The followup period averaged 120 months (range, 24-276 months). Eighteen patients have no evidence of disease at last followup. Treatment failures included one local recurrence, four regional metastases, and five distant metastases. Five patients died secondary to disease. Two patients are alive with disease, and three are alive with no evidence of disease after additional treatment. After aggressive surgical management with negative margins, 71% of the patients were alive without evidence of disease at the last followup, with a 5- and 10-year survivorship of 85%. Our goal is to review: (1) the effectiveness of preoperative imaging, (2) the role of adjuvant therapy, (3) survival after alternative resections, and (4) function after resection.     

Current controversies in oral lichen planus: report of an international consensus meeting. Part 2. Clinical management and malignant transformation

Despite recent advances in understanding the immunopathogenesis of oral lichen planus (LP), the initial triggers of lesion formation and the essential pathogenic pathways are unknown. It is therefore not surprising that the clinical management of oral LP poses considerable difficulties to the dermatologist and the oral physician. A consensus meeting was held in France in March 2003 to discuss the most controversial aspects of oral LP. Part 1 of the meeting report focused on (1) the relationship between oral LP and viral infection, with special emphasis on hepatitis C virus (HCV), and (2) oral LP pathogenesis, in particular the immune mechanisms resulting in lymphocyte infiltration and keratinocyte apoptosis. Part 2 focuses on patient management and therapeutic approaches and includes discussion on malignant transformation of oral LP.     

An update of the etiology and management of xerostomia

Salivary gland disease gives rise to salivary gland enlargement, pain, and prolonged xerostomia (dry mouth). Xerostomia is the most common long-standing problem for the majority of affected patients. There are many causes of dry mouth, with long-standing xerostomia being a particular problem in Sj?gren's syndrome and after radiation to the head and neck region. Xerostomia is usually managed with saliva substitutes, but a large number of potential systemic therapies of long-standing xerostomia now exist. Some-particularly immunosuppressants-are of fundamental interest for the potential reduction of gland damage in Sj?gren's syndrome but as yet are of limited clinical usefulness. Others, particularly pilocarpine and cevimeline, are, or have the potential to be, clinically useful in stimulating salivation by virtue of their action on cholinergic receptors.     

Patient survival after hip arthroplasty for metastatic disease of the hip

BACKGROUND: The hip joint is a common location for metastatic disease. Actual as well as impending fractures at this site are frequently due to mechanical instability after tumor invasion and are usually treated surgically with hip arthroplasty. The objective of this study was to analyze survival and influences on survival after hip arthroplasty for metastatic hip disease. METHODS: Two hundred and ninety-nine patients who had undergone a total of 306 hemiarthroplasty or total hip arthroplasty procedures for treatment of a pathologic or an impending pathologic hip fracture between 1969 and 1996 at our institution were included in this study. Data that had been acquired prospectively within the total joint registry of our institution were reviewed retrospectively. RESULTS: The median duration of survival after the arthroplasty was 8.6 months. The duration of survival was significantly associated with the site of the fracture, location of the primary tumor, and time from the diagnosis of the primary tumor to the surgery for the fracture (p < or = 0.05). The time from the diagnosis to the arthroplasty was a significant independent predictor of survival. CONCLUSIONS: Patients undergoing hip arthroplasty for metastatic disease have a limited life expectancy, with only 40% (120) of the 299 patients in our series still alive at one year after the surgery. By identifying prognostic factors regarding life expectancy, this study provides surgeons and oncologists with information with which to weigh risks and benefits of hip arthroplasty for individual patients preoperatively.     

Obstetric adversity and age at first presentation with schizophrenia: evidence of a dose-response relationship

OBJECTIVE: The purpose of the study was to determine if a dose-response relationship exists between obstetric adversity and age at first presentation with schizophrenia. METHOD: The Dublin Psychiatric Case Register was used to identify subjects with schizophrenia. Data on obstetric complications, social class of origin, and family history of psychiatric illness were obtained for those subjects. RESULTS: A total of 409 patients with ICD-9 schizophrenia were identified. Patients with a history of obstetric complications presented earlier to psychiatric services. As the number of complications increased, the mean age at first presentation decreased. This effect was independent of social class of origin and family history of psychiatric illness. CONCLUSIONS: Obstetric adversity exerts an independent influence on the age at first presentation with schizophrenia, in a dose-response manner. This finding supports the existence of a causal relationship between obstetric adversity and age at first presentation with schizophrenia.
