Maxillary sinusitis in adults: an evaluation of placebo-controlled double-blind trials

BACKGROUND: In general practice, acute sinusitis is frequently diagnosed and treated with antibiotics. OBJECTIVE: This study aimed to determine the evidence for the effectiveness of antibiotic treatment in acute maxillary sinusitis in adults by assessing the methodological quality of placebo-controlled double-blind randomized trials. METHOD: An evaluation by four raters through a 35-item scoring-scale for internal and external validity of all placebo-controlled double-blind randomized trials on acute sinusitis found between January 1966 and July 1996. RESULTS: Eighty-five trials were excluded because they were not placebo-controlled, double-blind, randomized, or were carried out in patients with chronic sinusitis or in children. The three remaining trials were performed in different populations (one in general practice) between 1973 and 1978. Only one study claimed superiority of antibiotic treatment. Different inclusion criteria and major outcome measures were used by the authors. The reliability of major outcome events was reported poorly or not at all and in two studies outcome measures were clinically inappropriate. The studies scored 30-62% of the maximum attainable score for internal validity and 10-20% for external validity. CONCLUSION: The effectiveness of antibiotic treatment in acute maxillary sinusitis in a general practice population is not based sufficiently on evidence.      

OVERHEATING IN BED AS AN IMPORTANT FACTOR IN MANY COMMON DERMATOSES

Background. Extensive questioning of patients with a wide variety of skin disorders led to the impression that nocturnal overheating was probably an important factor in the initiation and the perpetuation of many skin disorders. Methods. In order to test the hypothesis, 12 “clean-skinned” subjects (6M/6F) aged 18 to 45 years were monitored electronically every 30 seconds during an 8 hour sleep period (2300 to 0700 hours), sleeping under a standard 10 tog duvet. Results. All the subjects were too hot by 3 to 4°C. All showed changes in their EEG patterns with reduced REM sleep, increased awakenings, and all showed changes in their sleep stage patterns. In addition, they all showed evidence of increased sweating in the “heat-sink” area. Conclusions. The mechanisms where by such changes could be implicated in the precipitation and perpetuation of skin disease are discussed. “Lifestyle” modification as a very effective, noninvasive, therapeutic regime is recommended. Further research along these lines would probably be very valuable and instructive.     

Treatment of refractoriness to platelet transfusion by protein A column therapy

Ten thrombocytopenic patients (platelets < 10–24 × 10(9)/L) who were refractory to platelet transfusion were investigated for their responsiveness to staphylococcal protein A column therapy. Nine patients had previously been treated with steroids, intravenous immune globulin, and/or other forms of immunosuppressive therapy without improvement in their transfusion response. All patients were receiving multiple platelet transfusions without achieving 1-hour corrected count increments (CCIs) > or = 7500. Eight patients had antibodies that reacted with platelets and were directed against HLA class I antigens, ABO antigens, and/or platelet-specific alloantigens. Plasma (500-2000 mL) from each patient was passed over a protein A silica gel column and then returned to the patient. Patients received from 1 to 14 treatments. A positive response to protein A therapy was defined as at least a doubling of the pretreatment platelet count and/or two successive 10- to 120-minute posttransfusion CCIs > or = 7500. Following plasma treatments, 6 of 10 patients responded with daily platelet counts that averaged 48 +/− 11 × 10(9) per L as compared with counts of 16 +/− 7 × 10(9) per L (p < 0.0005) before treatment. Posttransfusion CCI values determined in four of these patients averaged 2480 +/− 810 and 10,010 +/− 3540 (p < 0.005) before and after treatment, respectively. In contrast, among the four unresponsive patients, platelet counts averaged 10 +/− 9 and 13 +/− 10 × 10(9) per L (p = NS), respectively, while posttransfusion CCIs were 700 +/− 1410 and 1520 +/− 2460 (p = NS), respectively.(ABSTRACT TRUNCATED AT 250 WORDS)     

Spontaneous reports of most distressing concerns in patients with inoperable lung cancer: at present,in retrospect and in comparison with EORTC-QLQ-C30+LC13

Patients with lung cancer experience considerable distress. Therefore, accurate methods for assessing distress and quality of life over time may play a key role for managing and evaluating palliative care. Alternatives to commonly used standardized questionnaires are individual measures. This study prospectively and retrospectively explored the concerns that 46 patients with inoperable lung cancer spontaneously reported as causing most distress close to diagnosis and 6 months later. Changes in content individually generated through a structured inductive freelisting were compared with EORTC-QLQ-C30+LC13 ratings. The results showed that patients perceived a wide variety of concerns as most distressing and that their concerns changed over time. Between 56 and 62% of these concerns were assessed by items included in the EORTC-QLQ-C30+LC13 questionnaires. Furthermore, patients’ reports of most distress from fatigue, pain and dyspnea were not always reflected in intensity ratings of comparable EORTC-QLQ-C30+LC13 items. These results indicate that items included in standardized measures are not always adequate to assess patients’ concerns, priorities and changes over time. In addition to standardized questionnaires, individualized measures may be useful in the clinical palliative setting for providing detailed information about the individual’s problems and prioritizations.     

Lethal Congenital Muscular Dystrophy with Arthrogryposis Multiplex Congenita: Three New Cases and Review of the Literature

Congenital muscular dystrophy (CMD) comprises a heterogeneous group of muscle disorders. We report on two stillborn sibs with early lethal CMD and a prematurely born boy who died within minutes after birth. The pregnancies were complicated by polyhydramnios. All presented with arthrogryposis multiplex congenita, severe muscle wasting, lung hypoplasia, and hydrops. The muscle biopsies showed fibrosis, variation in fiber size, and extensive fat replacement compatible with muscular dystrophy. Fatal CMD seems to be distinct from CMD with survival after birth and is probably autosomal recessively inherited.
