Necrobiotic xanthogranuloma without paraproteinaemia: marked improvement with psoralen ultraviolet A treatment.

Necrobiotic xanthogranuloma (NXG) is a rare granulomatous condition that is often associated with a paraproteinaemia and in some cases multiple myeloma. Treatment is therefore aimed at the underlying associated haematological abnormality. However, isolated NXG cases have been reported. We report a case of isolated NXG that responded very well to systemic psoralen ultraviolet A (PUVA) treatment. The rationale for this treatment was the successful use of PUVA treatment in other necrobiotic conditions such as granuloma annulare and necrobiosis lipoidica.

Financial performance among adult day centers: results of a national demonstration program.

OBJECTIVES: This paper describes the financial performance (defined as percent of total expenses covered by net operating revenue) of 16 adult day centers participating in a national demonstration program on day services for people with dementia, including examination of possible predictors of financial performance. METHODS: Participating sites submitted quarterly financial and utilization reports to the National Program Office. Descriptive statistics summarize the factors believed to influence financial performance. RESULTS: Sites averaged meeting 35% of expenses from self-pay and 29% from government (mainly Medicaid) revenue, totaling 64% of all (cash plus in-kind) expenses met by operating revenue. Examination of center characteristics suggests that factors related to meeting consumer needs, such as being open a full day (i.e., 7:30 am to 6:00 pm) rather than shorter hours, and providing transportation, may be related to improved utilization and, thus, improved financial performance. Higher fees were not related to lower enrollment, census, or revenue. CONCLUSIONS: Adult day centers are able to achieve financial viability through a combination of operating (i.e., fee-for-service) and non-operating revenue. Operating revenue is enhanced by placing emphasis on consumer responsiveness, such as being open a full day. Because higher fees were not related to lower utilization, centers should set fees to reflect actual costs. The figure of 64% of expenses met by operating revenue is conservative inasmuch as sites included in-kind revenue as expenses in their budgeting calculations, and percent of cash expenses met by operating revenue would be higher (approximately 75% for this group of centers).

Oxypentifylline in the management of recurrent aphthous oral ulcers: an open clinical trial.

OBJECTIVE: The purpose of this study was to determine the efficacy of oxypentifylline in the treatment of recurrent oral aphthous ulcers and to compare the results with those of previous studies. STUDY DESIGN: A 6-week open trial and a patient survey regarding pain were conducted at the Oral and Maxillofacial Surgery Unit, City General Hospital, Carlisle. Twenty-four patients (11 male and 13 female) were selected from sequential referrals involving complaints of recurrent oral ulcers. A 2-week pretrial period was used to record data pertaining to the occurrence, duration, and pain associated with ulcers. A 4-week period of treatment with oxypentifylline (400 mg administered orally 3 times daily) was followed by an assessment of improvement at the end of 6 weeks. RESULTS: The results were comparable to those of previous studies, with positive responses seen in 63.6% of male patients and 61.5% of female patients. However, recurrence of ulcers was noted in all patients once the drug was discontinued. This was attributed to the small size of the patient sample studied and to the relatively short duration of treatment. No significant side effects were noted. CONCLUSIONS: Double-blind, controlled studies are indicated for a definitive assessment of the efficacy of oxypentifylline in the management of recurrent oral aphthous ulcers. The encouraging results of this study support the suggestion that the use of oxypentifylline be considered in refractory cases of recurrent oral aphthous ulcers.

Maternal birthing positions and perineal injury.

A study to evaluate the relationship between maternal birthing position and perineal outcome was undertaken on 335 patients in a rural family physician's practice whose babies were delivered vaginally between December 1980 and December 1988. The most common birthing position used by the women was the semi-sitting position in the birthing bed (44%, n = 146). Ninety-four women (28%) gave birth from the conventional lithotomy position, 80 (24%) used the birthing chair, and less than 5% used a side-lying position. Almost 30% of the women gave birth with intact perineum; the incidence of episiotomy was 44%. The use of a particular position for delivery varied with parity, and multiparous women used the semi-sitting position in the birthing bed more frequently than did primiparous women. There was no statistically significant relationship between birthing position and perineal outcome for primiparous women. A statistically significant relationship between delivery position and perineal outcome was found for multiparous women. Multiparous women using the birthing bed were more likely to have less perineal trauma than women giving birth on the delivery table.

[Influenza vaccination of children with hemophilia]. / Szczepienia przeciw grypie dzieci chorych na hemofilie.

51 haemophilic children aged from 7 to 16 years was vaccinated against influenza in Paediatric Department of Haematology and Oncology in November and December of 1993. Each dose of subunit vaccine manufactured by Wyeth-USA, contained 15 micrograms of each haemagglutinin strains as recommended for the season. The antibody level was studied before and after influenza vaccination in vaccinated and control group as well. 5-time rise of geometric mean antibody titre was found for H1N1 and H3N2 antigens after vaccination of the children group. Slightly lower, 2.7-time rise of GMT was showed for HB haemagglutinin of influenza virus. There was no significant rise of GMT for any among three studied virus haemagglutinin.

Dementia care and respite services program.

In 1987 The Robert Wood Johnson Foundation announced the creation of the Dementia Care and Respite Services Program (DCRSP), the first national demonstration project to focus on day center and respite services for persons with dementia. The intent of $5.1 million, 4-year (1988-1992) program was to demonstrate that nonprofit day centers could provide financially viable programs and services needed by people with dementia and their caregivers. Seventeen grantees in 13 states, representing 21 different organizations and operating 24 day centers, participated in the project throughout the entire 4 years. The DCRSP has provided the first overview of dementia-specific day programs in the United States, with specific insight as to who is being served (e.g., participant and caregiver characteristics), types of assistance needed in relation to activities of daily living, and the most common behavior problems being exhibited. In addition, results of the 4-year project support the fact that community-based day centers can effectively care for people with dementia, a demand for these services does exist, and families consider these services of sufficient value that they are willing to pay for them out-of-pocket. Results also show that nonprofit day centers can become financially viable programs if attention is given to factors such as providing consumer-responsive services, charging what services actually cost, and having a high level of community visibility. The net result is increased net operating revenue with improved financial performance and enhanced long-term stability.

Influenza.

Influenza is the most frequent cause of acute respiratory illness requiring medical intervention because it affects all age groups and because it can recur in any individual. During the past three decades, efforts to prevent and control influenza have focused primarily on the use of inactivated influenza vaccines in elderly people and in individuals with chronic medical conditions that put them at risk for complications. However, the continuing impact of influenza in these and other population groups has motivated the development of novel approaches for prevention and control of influenza. Several important advances in the field of influenza have occurred in the last few years. An experimental live, attenuated, intranasally administered trivalent influenza vaccine was shown to be highly effective in protecting young children against influenza A H3N2 and influenza B. New antiviral drugs based on the structure of the neuraminidase molecule were assessed in clinical trials and found to be effective against influenza A and B viruses. The expected use of these new antiviral agents has accelerated the development of rapid point-of-care diagnostic tests. The availability of new diagnostic tests, new antiviral drugs, and new vaccines will undoubtedly alter our approaches to influenza control and have an impact on clinical practice.

Development and operation of the Wisconsin Research Network.

In 1987, the Wisconsin Academy of Family Physicians developed the Wisconsin Research Network (WReN) to support practice-based primary care research throughout Wisconsin. WReN has three objectives: to support the research efforts of individual physicians in community practices, to facilitate collaborative research among practicing physicians, and to provide academically based investigators with access to community practice sites. Due to a policy of actively encouraging membership, WReN has grown to 460 members during its 4-year history. Five WReN-supported papers have been published, and 22 state and national level presentations of WReN-supported research results have been made. Competitive grants totaling more than $2 million have been awarded to university-based investigators for studies using the resources of WReN. This paper describes the development, organization, and success of WReN as well as the challenges which must be addressed.

Influenza surveillance--United States, 1992-93 and 1993-94.

PROBLEM/CONDITION: CDC conducts active surveillance annually from October through May on the emergence and spread of influenza virus variants and the impact of influenza-related morbidity and mortality. Influenza activity is also monitored throughout the year by passive surveillance. REPORTING PERIOD COVERED: This report summarizes U.S. influenza surveillance from October 1992 through May 1994. DESCRIPTION OF SYSTEM: Influenza surveillance comprises four components, three of which provide weekly data from October through May: a) state and territorial epidemiologists provide estimates of local influenza activity; b) approximately 140 sentinel physicians report their total number of patient visits and the number of cases of influenza-like illness; and c) approximately 70 collaborating laboratories of the World Health Organization (WHO) report weekly influenza virus isolations and submit selected influenza isolates to CDC for antigenic analysis. Throughout the year, vital statistics offices of 121 cities report deaths related to pneumonia and influenza (P&I), providing an index of the impact of influenza on mortality. RESULTS: Influenza B viruses predominated during the 1992-93 influenza season, but influenza A(H3N2) isolates increased and were associated with outbreaks in nursing homes at the end of the season. The increase in influenza A(H3N2) activity was associated with a rise in P&I-related mortality. Preseason outbreaks of influenza A(H3N2) virus were reported during August and September 1993 in Louisiana. In the past, preseason outbreaks of influenza have been associated with earlier than usual epidemic-level activity. During the 1993-94 influenza season, activity rose during November and December and peaked earlier than usual, during the last week of December and the first week of January; influenza A(H3N2) viruses predominated. INTERPRETATION: The change in predominance from influenza B to influenza A in the spring of 1993 emphasizes the importance of annual influenza surveillance. Although influenza vaccine is effective against both influenza A and B, the antiviral drugs amantadine and rimantadine are effective only against influenza A. Outbreaks during the summer of 1993 emphasize that influenza should be considered a possible cause of respiratory infections during summer and early autumn. ACTIONS TAKEN: Surveillance data were provided weekly throughout the influenza season to public health officials, WHO, and health-care providers.
