Phase II trial of 10 deaza-aminopterin in patients with bladder cancer

Summary Deaza-aminopterin is a folate analog which is transported more rapidly than methotrexate into cells and appears to be more active than methotrexate against human and animal tumor in vitro. Fifteen patients with advanced urothelial tract cancer were given deaza-aminopterin 30–37.5 mg/m² IV QW. In responding patients drug was given QOW after 4–6 consecutive doses. Doses were escalated or de-escalated by 7.5 mg/m² depending on toxicity. Twelve patients had received prior chemotherapy which included methotrexate in nine. Three patients achieved a partial remission lasting 1, 3, and 3 months respectively: all responders had previously failed methotrexate after an initial response to a methotrexate containing regimen. None of the six patients who were methotrexate naive responded to deaza-aminopterin; 3 subsequently received methotrexate without response. Mild mucositis was universal and in 5 was severe. Six patients had an increase in liver transaminases probably secondary to anti-folate hepatotoxicity. Other toxicities included diarrhea, nausea, skin rash and fever. Further studies are needed to define the precise efficacy of deaza-aminopterin in patients with urothelial tract cancers.     

Temporomandibular joint eminence augmentation by down-fracture and inter-positional cartilage graft. A new surgical technique.

A new surgical technique for the treatment of recurrent temporomandibular joint subluxation or dislocation is described. Following a horizontal osteotomy and down-fracture of the articular eminence an inter-positional bovine cartilage xenograft is inserted in order to augment the vertical height of the eminence. The procedure combines simplicity with minimal post-operative morbidity. The increase in eminence height is both predictable and stable.     

Carcinoma-associated dermatomyositis responding to plasmapheresis

We report a case of severe carcinoma-associated dermatomyositis which, having shown no response to conventional treatment, improved markedly within 48 h of plasmapheresis. We believe that this is the first time that dermatomyositis associated with an advanced carcinoma has been reported to respond in this way. Dermatomyositis can prove extremely difficult to treat and sometimes fails to respond even to very high doses of steroids and immunosuppressants. There is currently only a single report of the use of plasmapheresis in adult dermatomyositis. We therefore wish to support the findings of Dau and draw attention to the value of this therapeutic option in refractory dermatomyositis.     

Phase II trial of Didemnin B in patients with advanced renal cell carcinoma

Summary Twenty-three patients with advanced renal cell cancer were treated with Didemnin B. One partial response was achieved (5%) in 21 evaluable patients. An allergic reaction was noted in four patients including one patient with anaphylaxis. Didemnin B is not recommended in the treatment of renal cell carcinoma.     

Predictors of non-spine fracture in elderly men: the MrOS study.

We examined determinants of nonvertebral fracture in elderly men from six U.S. communities followed an average of 4.1 years. Six clinical risk factors predicted fracture risk independent of hip BMD: tricyclic antidepressant use, previous fracture, inability to complete a narrow walk trial, falls in previous year, age > or =80 years, and depressed mood. INTRODUCTION: There are few prospective studies of fracture determinants in men. We examined the associations between a comprehensive set of clinical risk factors and risk of nonspine fracture in older men and whether determinants of fracture risk were independent of total hip BMD. MATERIALS AND METHODS: A total of 5995 men > or =65 years of age were recruited from six communities in the Unites States and followed prospectively for an average of 4.1 years. Baseline assessments of demographic, lifestyle, medical history, functional status, anthropometry, and cognitive, visual, and neuromuscular function were assessed by questionnaire or examination. Triannual mailed questionnaires ascertained incident fracture; reported fractures were adjudicated by physicians using medical records and X-ray reports. Proportional hazards models were used to develop multivariable models, selecting variables and controlling for BMD. RESULTS: Of 5876 men, 4.7% (N = 275) reported an incident nonspine fracture during follow-up (11.46/1000 person-years). Tricyclic antidepressant use (hazard ratio [HR], 2.36; 95% CI, 1.25-4.46), history of fracture at or after age 50 (HR, 2.07; 95% CI, 1.62-2.65), inability to complete a narrow walk trial (HR, 1.70; 95% CI, 1.23-2.34), falls in previous year (HR, 1.59; 95% CI, 1.23-2.05), age > or =80 years (HR, 1.33; 95% CI, 1.01-1.76), depressed mood (HR, 1.72; 95% CI, 1.00-2.95), and decreased total hip BMD (HR, 1.53; 95% CI, 1.34-1.74) were independently related to increased risk. Compared with having none (48.0% of men), having three or more of the clinical risk factors (4.9% of men) increased fracture risk 5-fold, independent of BMD. Having three or more risk factors and being in the lowest tertile of BMD was associated with a 15-fold greater risk than having no risk factors and being in the highest BMD tertile. CONCLUSIONS: Several clinical risk factors were independently associated with nonspine fractures in elderly men. The combination of multiple risk factors and low BMD was a very powerful indicator of fracture risk.     

Suffering: a relatively unexplored phenomenon among family caregivers of non-institutionalized patients with cancer

Suffering is a phenomenon with physical and emotional components. Although several studies have drawn attention to the needs of, and demands placed on families who provide care for patients with a diagnosis of cancer at home, few have discussed the suffering which many of these caregivers experience. This paper will illustrate the phenomenon of suffering as seen in the responses made by family caregivers of patients with cancer. Eighty-three family caregivers drawn from a probability sample of patients with a diagnosis of cancer were interviewed in their homes to determine needs they encountered in their caregiving roles. The caregivers consisted of 43 males and 40 females, with mean ages of 53 and 54 years respectively. Families not only identified their needs, they also indicated several areas which were for them sources of suffering. The findings revealed that family suffering often stemmed from fear of loneliness; uncertainty about the future (their own and that of the patients); lifestyle disruption; communication breakdown; lack of support; and their sense of helplessness. These findings suggest that health professionals, particularly nurses, who work with families in their homes, must be alert and sensitive to cues and circumstances which could indicate suffering, and in so doing, take the necessary steps to ameliorate their situation.     

Orthognathic surgery for the treatment of chronic self-mutilation of the lips.

Self-mutilation by lip chewing is an uncommon problem, but may result in severe mutilation, infection and loss of tissue, with associated scarring. Many modalities of treatment have been proposed in the literature with variable success and morbidity to the patient. Alternative techniques involving orthognathic surgery to create an anterior open bite are described which may result in cessation of self-mutilation. A case is presented with a 13-year follow-up, the anterior open bite is still present, and no recurrence of self-mutilation.
