[The prognosis of surgery on the elderly. Proposal for a parametric evaluation].

BACKGROUND AND AIMS: To data there are no preoperative systems of evaluating surgical risk specifically in geriatric patients. Given that it was thought useful to formulate a score-based prognostic system for these patients based on surgical risk, the authors collected a wide range of preoperative data with the aim of identifying the easily determined variables. METHODS: While data from other hospital centres are in the process of being collected, the authors report the data for 122 over 65-year-old patients who underwent elective surgery up until 30-1-1996 out of a total of 329 hospitalized patients. In addition to a wide series of objective, laboratory and instrumental data, the study also took into account the pathology requiring to surgery, any associated morbid conditions, psychic and social conditions, the type of surgery and local and/or general postoperative complications. RESULTS: Hernia of the abdominal wall were found to be the most frequent cause of surgery (41 cases), followed by 27 neoplasias of various organs and biliary lithiasis (20 cases). Cardiovascular diseases were the most common associated pathologies (85 patients). A total of 13 major and 80 medium operations were performed, including 16 cholecystectomies. Among the general complications, an altered acid-base balance was found in 7 patients. Two deaths were recorded within 30 days of surgery. When the data collection is complete, the results will be analysed statistically in order to obtain a numerical calculation of the coefficients of risk correlated to the individual variables. CONCLUSIONS: This will enable the criteria of operability to be broadened, thereby allowing surgery to be performed in those patients who are currently excluded merely on the basis of the personal judgement of the surgeon and anesthetist.

Management of recurrent stricture of appendicostomy in continent neobladder (Indiana pouch) with Memotherm ureteral stent: case report.

The authors report their experience in the treatment of recurrent stricture of the appendiceal stump in continent diversion (Indiana pouch) after cystectomy by means of the Memotherm ureteral stent. The patient presented was treated successfully with this device after failure of repeat cold-knife incisions of the stricture. At 9-months' follow-up from positioning, the stent is in place, covered by mucosa. Self-catheterization of the pouch is easily performed five or six times a day with a 12F catheter.

[Conservative treatment of high-risk (T1G3) transitional carcinoma].

OBJECTIVE: This study evaluates the outcome of patients (pts) with primary T1G3 bladder cancer treated by transurethral resection (TUR) alone or followed by intravesical prophylaxis (BCG/Doxorubicin). Cistectomy was considered at disease progression. METHODS: Between 1/89 and 5/95 thirty-one pts with primary T1G3 bladder cancer were treated by TUR, in 24 followed by intravesical prophylaxis (13 with BCG, 11 with Doxorubicin). 7 pts had only TUR. RESULTS: At 42 months median follow up 45.2% pts (14/31) are disease free. The recurrence rate was 25.8% (8/31) and progression of disease was seen in 29.0% (9/31); mortality rate was 22.6% (7/31). In 13/31 pts treated by TUR + BCG 53.8% pts (7/13) are disease free. The recurrance rate was 23.1% (3/13) and progression of disease was seen in 23.1% (3/13) of cases; mortality rate was 23.1% (3/13). In 11/31 pts treated by TUR+Doxorubicin 54.5% pts (6/11) are disease free. The recurrance rate was 18.2% (2/11), progression of disease was seen in 27.3% (3/11) of cases of mortality rate of 9.1% (1/11). In 7/31 pts treated by TUR alone 14.3% pts (1/7) are disease free. The recurrance rate was 42.9% (3/7) and progression of disease was seen in 42.9% (3/7) of cases and mortality rate of 42.9% (3/7). Cistectomy was considered in 4 pts (3 for disease progression and 1 because of no disease free interval). The other pts with progression were not treated surgically because of their poor performance status. CONCLUSION: At a 42 months median follow up 77.4% pts (24/31) are alive (83.3% pts treated by TUR+intravesical prophylaxis). 64.5% pts (20/31) still have their bladder (66.6% pts treated by TUR+intravesical prophylaxis (16/24). We did not find a significative difference between prophylaxis with immunotherapy or chemotherapy. In conclusion we believe that the conservative management of high risk bladder transitional cell carcinoma T1G3 is feasible and allow us to plan cistectomy only in pts with progression or recurrance with no free interval without losing survival.

[Stents in the treatment of stenosis of the entero-urethral junction in continent diversion: case reports].

Strictures of entero-urethral anastomosis in orthotopic neobladder and of the catheterizable conduit in continent diversion after cystectomy are seldom encountered; they are usually treated with dilation, TUR or cold incision. 3 cases that came to our observation are presented. The first was treated with TUR after neo-bladder neck stricture in orthotopic neobladder; total incontinence occurred after this procedure. The patient at present is waiting for AS800 artificial sphincter implant. The second patient had similar features. After repeat TUR a prostacoil removable stent was placed through the stricture and removed after 5 months. At 12 months from removal the patient is continent and doesn't present clinical evidence of restriction. The third patient underwent cystectomy with Indiana continent pouch. After 4 months increasing problems in self catheterization occurred due to stricture of the catheterization conduit (appendix). He was treated twice with cold incision with early recurrence of the stricture. A permanent Memotherm stent (indicated for urethral strictures) was placed inside the appendix. After one month self catheterization was started again. At a 2 months follow up there is no evidence of stricture. In our experience, even if anecdotal, we have verified that treatment of this kind of strictures with TUR can cause incontinence or expose to further recurrences. 2 of the cases presented were treated with different kind of stents; the outcome is good even if the follow up is still short. We believe that this kind of treatment can be considered in selected cases.

Economic status of families living with multiple sclerosis.

A nation-wide survey of 604 families living with multiple sclerosis was conducted. The sample was recruited through local chapters of the National Multiple Sclerosis Society and the public press. This paper describes the economic impact of the disease on families. There were 427 families in which the woman had multiple sclerosis and 177 families in which the man had the disease. The average duration of the disease was 10 years. Family income was well above the national median income. Thirty-nine per cent of the men and 19% of the women with multiple sclerosis retired because of disability. Income was inadequate to pay for medical expenses in 21% of the families and 25% had inadequate funds to meet basic living expenses. While 80% of the families had health care insurance, for 28% of the families the insurance was inadequate to cover the cost of their illness. The number of children living at home and the amount of health care bills paid out-of-pocket failed to explain why families in the high income group had difficulty meeting their expenses. Factors other than income and proportion of medical expenses covered by insurance determine the economic impact on the family. If health care providers are going to meet all the needs of a family living with multiple sclerosis, a more comprehensive assessment of their economic status is needed.

Persons with cancer and their return to the workplace.

Over 5 million persons are living today with a diagnosis of cancer. Maintaining employment after a diagnosis of cancer and even during therapy is a major challenge for an increasing number of individuals. The majority of preretirement persons with cancer who have attempted a return to the workplace have confronted a variety of issues and barriers. Social scientists and legal and health care professionals have attempted to identify particular practices and issues that have affected the return to work experiences of those with a diagnosis of cancer. There has not been a program in nursing research that has systematically tested clinical interventions which effect return-to-work outcomes in persons with cancer. Understanding the return-to-work experience is an essential prerequisite to planning clinical nursing therapeutics and assistance to persons with cancer who consider maintaining their worker role. Environmental and personal factors that influence a successful return to the workplace, plus the human responses manifested in the return experience are reviewed in this article. Clinical implications are drawn for nurses who can facilitate the return-to-work for an individual with cancer through interventions that eliminate or alter barriers to the successful return.

Regional coronary hemodynamic effects of diltiazem in man.

We evaluated the changes in regional coronary hemodynamics induced by diltiazem, 0.25 mg/kg intravenously, in nine patients with 75% to 90% diameter stenosis of the left anterior descending coronary artery (LAD) (group 1) and in 10 patients with 100% occlusion of the LAD and collaterals to the distal LAD (group 2). Although diltiazem induced similar changes in systemic hemodynamics in the two groups, a decrease in anterior coronary vascular resistance (ACVR) and an increase in great cardiac vein flow (GCVF) were observed after administration of diltiazem in all patients in group 1 but in only 6 of 10 patients in group 2 (subgroup 2B). ACVR increased and GCVF decreased after administration of diltiazem in 4 of 10 patients in group 2 (subgroup 2A). Clinico-angiographic characteristics, origin of collaterals, and diltiazem-induced changes in systemic hemodynamics were similar in subgroups 2A and 2B. Thus diltiazem increases coronary flow distal to a stenotic coronary artery but can decrease regional coronary flow and increase regional coronary resistance in a minority of patients with an occluded coronary artery supplied by collaterals, probably through a steal mechanism.

A comparison of discharge teaching on the consequences of brain injury.

Cognitive dysfunction is a common consequence of brain injury. Frequently, however, this phenomenon is not discussed with family caregivers before the patient's discharge from the acute care setting. A discharge teaching videotape was developed, which presented how the most common cognitive dysfunctions experienced postbrain injury affect activities of daily living. The ability to extrapolate appropriate patient care techniques after receiving discharge instructions on cognitive dysfunctions was tested by a posttest only experimental design study using a control and experimental group. The results indicated that family caregivers who received instruction on cognitive dysfunction were more informed about brain injury-induced behavior and better prepared to help loved ones compensate for cognitive dysfunctions.

Bladder dysfunction: a remedial social problem.

Urinary bladder dysfunction is a leading disability of persons with multiple sclerosis. The study reported here demonstrates that the critical management of this neurologic deficit can improve the patient's quality of life in terms of personal, social, and occupational activities. The urodynamic studies of urinary flow rate, voiding cystourethrography, and positional cystometrography were used to establish the type of neurogenic bladder (areflexic, uninhibited, or mixed). Management regimens were individualized using a combination of anticholinergic or cholinergic drugs, intermittent self-catheterization, and managed fluid intake and voiding.

Urinary bladder dysfunction as a remedial disability in multiple sclerosis: a sociologic perspective.

Forty-two patients formed the sample for this study. They represented a self-selected subset of 115 patients who complained of bladder dysfunction as a disability secondary to multiple sclerosis. The study generated data on previous management and results, subjects' desired current intervention goals, urodynamic evaluation, and current intervention outcomes. Results indicated that bladder dysfunction disabilities are either ignored or mismanaged and that the disability can be reduced to the patient's satisfaction using clinically available diagnostic methods and indicated management.

Nursing care of the MS patient.

The challenge of multiple sclerosis (MS) surpasses the challenge offered to the nurse by many other diseases. The multiplicity of lesions, variety of symptoms, uncertain course, and lack of a cure or even a universally effective treatment all contribute to the complexity of providing care to the person with MS. The chronic aspects of this demyelinating disease emphasize the need for care that cuts across the primary, acute, or long-term setting and includes the maintenance of physical, psychosocial, and social health; evaluation and management of symptoms; and appropriate referrals. A framework that centers on key social and psychological problems in the daily experience of chronically ill persons will be used as the basis for carrying out the process of nursing as defined by the Standards of Nursing Practice.

Living with chronic illness: social support and the well spouse perspective.

Progressive neurologic disease has a significant impact on family members, particularly those living with and caring for a homebound adult. Focus groups were conducted with women who were the primary caregiver for their disabled husband. The women described themselves as being restricted to the home by caregiving requirements. Multiple sclerosis was a critical personal hardship for them, involving persistent struggle that often resulted in anger and frustration. Because of the social isolation created by their caregiving responsibilities, these women depended on their disabled husband for support. Yet, never having time away from the husband strained the marital relationship and threatened the supportive nature of the relationship. The women in this study found it necessary to have personal time and space away from their husband. They created space for themselves by setting apart a place in the home that was theirs or by declaring time out for themselves. These strategies helped them avoid or reduce negative outcomes of the social support received from their husband.
