Surgical resection in the management of small cell carcinoma of the lung

In an attempt to define the role of initial surgical resection in patients with undifferentiated small cell carcinoma of the lung, we reviewed the experience of the Veterans Administration Surgical Oncology Group (VASOG). One hundred forty-eight patients with small cell carcinoma of the lung had undergone a potentially "curative" resection. This represented 4.7% of "curative" resections carried out in four major prospective adjuvant chemotherapy trials. In the early trials (101 patients), 16 patients (15.8%) died within the first 30 postoperative days. These patients have been excluded from the analysis of long-term survival, since in the more recent trials postoperative deaths were excluded prior to randomization. In the 132 patients remaining, the 5 year survival rate by the life-table method was 23.0%. The tumor of each was classified pathologically by the TNM system. Five-year survival rates for each category were as follows: T1 N0 M0 59.9%, T1 N1 M0 31.3%, T2 N0 M0 27.9%, T2 N1 M0 9.0%, and any T3 or N2 3.6%. The effect of postoperative adjuvant chemotherapy was evaluated in each of the trials. No beneficial effect of the adjuvant therapy was noted with a one or two course regimen of either nitrogen mustard or cyclophosphamide, but possible benefit, although not significant, was noted in a prolonged intermittent chemotherapy trial of cyclophosphamide either alone or alternating with methotrexate. In the most recent trial of prolonged intermittent courses of 1-(2-chlorethyl)-3-cyclohexyl-l-nitrosourea (CCNU) and hydroxyurea, a 5 year survival rate of 80.8% was noted in those receiving adjuvant chemotherapy as compared to a 38.1% in the control group. We conclude that resection is definitely indicated in patients with T1 N0 M0 lesions and probably indicated in those with T1 N1 M0 or T2 N0 M0 lesions. Primary surgical resection is contraindicated in patients with any other TNM category.     

Quality measurement and control in physician decision making: state of the art.

The status of the concept of controlling the quality of physicians is reviewed as are studies that have been done on methods to measure and improve quality. The conclusions are dismal given the rhetoric and actions on attempts to measure and control quality of physician decision making. Massive attempts are being made, for example, mandating PSROs to monitor quality before there is a methodology. Cost and quality reviews have, at most, a marginal impact and do not deserve the expenditures to conduct them. Studies on utilization review show minimal impact on reducing utilization. Administrative reviews reduce utilization for certain specific, narrowly defined procedures such as injections. There is no operational definition of "unnecessary" utilization. The tendency is to regard the lowest levels as optimal, presumably because they result in lower expenditures. Bureaucratic reviews do not provide incentives to decision makers the way various types of HMO delivery types do from current evidence. Hence, HMOs, deductibles and coinsurance, and competition have greater promise for limiting expenditures than do utilization reviews. Quality audits are also marginally effective because of limited promise of changing provider behavior given current methods of doing so. They miss the organizational aspects in which incentives are generated. Research is needed, therefore, on alternative forms of quality and cost control such as HMOs, physician risk sharing, competitive models, and deductibles and coinsurance. Until the much needed research has been done, the amount of resources spent on review should be minimized. In the meantime, the review processes should concentrate on extreme variations of very narrowly defined criteria of proven validity while improving the review methodology by systematic research on quality monitoring.     

New non-cocaine-containing topical anesthetics compared with tetracaine-adrenaline-cocaine during repair of lacerations

OBJECTIVE: To compare the effectiveness of three new topical anesthetics that do not contain cocaine (prilocaine-phenylephrine, tetracaine-phenylephrine [tetraphen], and tetracaine-lidocaine-phenylephrine) to that of tetracaine-adrenaline-cocaine (TAC) during laceration repair in children. DESIGN: Prospective, randomized, double-blind clinical trial. SETTING: The emergency department of an urban children's hospital. PARTICIPANTS: Children 1 year of age or older with a laceration /= 5 years of age using a visual analogue scale (VAS). Suture technicians, research assistants, and parents also scored pain using a seven-point Likert scale. In addition, suture technicians completed an anesthetic effectiveness scale. RESULTS: There was consistently no difference demonstrated between the effectiveness of tetraphen and that of TAC for each outcome measure of each observer group. A statistically significant difference was seen among anesthetics when comparing VAS and Likert scale scores of suture technicians and Likert scale scores of research assistants. Based on post hoc analyses, these statistically significant differences were between TAC and prilocaine-phenylephrine (suture technician VAS and Likert scale) and between TAC and tetracaine-lidocaine-phenyl-ephrine (suture technician Likert scale), but not between TAC and tetraphen. When power analyses were performed using alpha = 0.05 and beta = 0.20, it was possible to detect a difference of 1.2 VAS units for each of the observer groups. Based on anesthetic effectiveness scale scores, the three new topical preparations collectively performed significantly better on the face and scalp than on the extremities (relative risk = 1.83; 95% confidence interval 1.20 < relative risk < 2.79). CONCLUSION: This study demonstrated the effectiveness and safety of three new non-cocaine-containing topical anesthetics. Consistently, there was no statistical difference demonstrated between the effectiveness of tetraphen and that of TAC for each outcome measure of each observer group. Tetraphen offers an effective alternative to TAC during laceration repair in children.     

Satisfaction with midwife-managed care in different time periods: a randomised controlled trial of 1299 women.

OBJECTIVE: To compare women's satisfaction with midwife-managed care with 'shared care' over three different time periods. DESIGN: Randomised controlled trial. SETTING: Glasgow Royal Maternity Hospital, Glasgow, UK. PARTICIPANTS: 1299 women experiencing normal pregnancy (consent rate: 82%). Six hundred and forty-eight women were randomised to midwife-managed care and 651 to 'shared care'. METHODS: Three self-report questionnaires were sent to women's homes. The questionnaires examined: satisfaction with antenatal care at 34-35 weeks' gestation, and satisfaction with intrapartum, hospital- and home-based postnatal care at seven weeks postnatally. The third questionnaire reviewed satisfaction with intrapartum care seven months after delivery. FINDINGS: Women in both groups were satisfied. However, women in the midwife-managed group were more highly satisfied in relation to the dimensions examined: relationships with staff, information transfer, choices and decisions, and social support. The differences between the two groups were evident for all time periods (i.e. antenatal, intrapartum and postnatal periods) and were sustained at seven-month follow-up. This is illustrated in the mean scores for relationships with staff, as measured at 34-35 weeks' gestation (possible range -2; very negative attitudes to 2; very positive attitudes). Women in the midwife-managed group scored a mean of 1.22 compared to 0.74 for the 'shared care' group (mean diff: 0.48; 95% CI: 0.42 to 0.55). While women in both groups were more likely to make positive rather than negative comments in open-ended questions, the midwife-managed group were more likely to make positive comments whereas the 'shared care' group were more likely to make negative comments. CONCLUSION: Midwife-managed care for healthy pregnant women which is integrated into existing services improves satisfaction with antenatal, intrapartum and postnatal care.     

Solitary retinovitreal abscess as the initial manifestation of cryptococcosis

In a 63-year-old white man with a history of long-term use of systemic corticosteroids for polyarteritis nodosa, progressive clouding of vision in the right eye developed over a 2-month period. Cytologic analysis of a fine-needle aspiration biopsy of a solitary fluffy retinovitreal mass demonstrated Cryptococcus neoformans. Subsequent cerebrospinal fluid cultures were also positive for C. neoformans. Systemic antifungal therapy was given using amphotericin-B and 5-fluorocytosine. Proliferative vitreoretinopathy developed in the right eye within 8 months. Three small yellow retinal lesions, which later resolved, developed in the fellow eye.     

Fluorescein angiography complication survey

This is a report on the results of a national survey designed to study the nature and frequency of moderate and severe complications of intravenous fluorescein angiography. In this survey, 2434 responding ophthalmologists reported on 221,781 fluorescein angiograms performed in the year 1984. Adverse reactions were classified as mild, moderate, severe, and death, depending on the duration of the effect, the necessity for medical intervention, the time required for its resolution, and the final outcome. The frequency rate for a moderate reaction was (1:63), for a severe reaction (1:1900), and for death (1:222,000). A review of previous studies on adverse reactions to the drug, a compilation of suggested methods for the amelioration and prevention of the complications, and a comparison of the responses of the general ophthalmic public to the members of The Macula Society are also reported.     

Relationship of pertussis immunization to the onset of neurologic disorders: a retrospective epidemiologic study

A retrospective epidemiologic study examining the relationship of the time of onset of neurologic disorders with the time of pertussis immunization in two cohorts of children who received pertussis immunization at different ages is reported. Before April 1970, children in Denmark were vaccinated with diphtheria and tetanus toxoids with pertussis vaccine at 5, 6, 7, and 15 months of age. Since 1970, children were given monovalent pertussis vaccine at 5 and 9 weeks and at 10 months of age. A total of 554 cases of epilepsy with onset between 28 days and 24 months of age were reviewed, 286 from the 1967-1968 period and 268 from the 1972-1973 period. There was no relationship between the age of onset of epilepsy and the scheduled age of administration of pertussis vaccine. A total of 2199 children with febrile seizures were reviewed, 830 from the 1967-1968 period and 1369 from the 1972-1973 period. There was a statistical association between first febrile seizures and the scheduled age of administration of pertussis vaccine (p = 0.004). No relationship between pertussis immunization and the occurrence of central nervous system infections was noted.
