The chronic Epstein-Barr virus syndrome is a poorly defined symptom complex characterized primarily by chronic or recurrent debilitating fatigue and various combinations of other symptoms, including sore throat, lymph node pain and tenderness, headache, myalgia, and arthralgias. Although the syndrome has received recent attention, and has been diagnosed in many patients, the chronic Epstein-Barr virus syndrome has not been defined consistently. Despite the name of the syndrome, both the diagnostic value of Epstein-Barr virus serologic tests and the proposed causal relationship between Epstein-Barr virus infection and patients who have been diagnosed with the chronic Epstein-Barr virus syndrome remain doubtful. We propose a new name for the chronic Epstein-Barr virus syndrome--the chronic fatigue syndrome--that more accurately describes this symptom complex as a syndrome of unknown cause characterized primarily by chronic fatigue. We also present a working definition for the chronic fatigue syndrome designed to improve the comparability and reproducibility of clinical research and epidemiologic studies, and to provide a rational basis for evaluating patients who have chronic fatigue of undetermined cause.

Chronic fatigue syndrome (CFS) is an illness which may be mild or completely disabling. Clients who return with recurring non-related symptoms and no specific diagnosis may suffer from CFS. The symptoms of CFS are numerous and varied, including fatigue, malaise, myalgias, difficulty concentrating, headaches and sore throat. Patient complaints seem out of proportion to the physical findings, which may be normal. There is no cure for this chronic disease. Therapy is primarily symptomatic. The role of the health care provider is to recognize this confusing disorder and help the patient and family cope with its many effects.

In the course of a prospective immunoepidemiological study of homosexual men in Sydney, seroconversion to the AIDS-associated retrovirus (ARV) was observed in 12 subjects. Review of the clinical files defined an acute infectious-mononucleosis-like illness in 11 subjects. The illness was of sudden onset, lasted from 3 to 14 days, and was associated with fevers, sweats, malaise, lethargy, anorexia, nausea, myalgia, arthralgia, headaches, sore throat, diarrhoea, generalised lymphadenopathy, a macular erythematous truncal eruption, and thrombocytopenia. In 1 subject an incubation period of 6 days after presumed exposure to ARV was determined and in 3 subjects seroconversion took place 19, 32, and 56 days after onset. Comparison of T-cell subsets before and after the acute illness showed inversion of T4:T8 ratio in 8 subjects, due to increased numbers of circulating T8+ cells. These findings support the notion of an acute clinical, immunological, and serological response to infection with ARV which should be considered in the differential diagnosis of mononucleosis-like syndromes in groups at high risk for the development of AIDS.

The obstetrical anaesthesia experience of the Winnipeg Women's Hospital from 1975 to 1983 was reviewed (n = 22,925 infants). Use of narcotics in labour for analgesia decreased from 38.7 to 18.3 per cent of the deliveries. For analgesia during spontaneous vaginal deliveries, epidural anaesthesia increased from 6.0 to 24.0 per cent, inhalational analgesia decreased from 53.7 to 3.2 per cent while "no anaesthetic intervention" rose from 40.3 to 72.8 per cent. Use of epidural anaesthesia for Caesarean section increased from 58.7 to 82.6 per cent. The most common acute complications of anaesthesia were hypotension and inadvertent dural puncture during epidural catheterization. The incidence of hypotension decreased from 28.3 to 17.4 per cent during the nine-year period. Dural puncture decreased from 4.7 to 1.1 per cent of all epidural administrations. Postpartum complaints (that were thought to be related to anaesthesia) were mainly headache, back pain and sore throat. The incidence of these complaints also decreased over the study period.

In all, 175 young (15-40 yr) patients received either spinal anaesthesia with bupivacaine (104 patients) or general, balanced anaesthesia (71 patients) for orthopaedic surgery of the lower extremities. Each patient was interviewed before the operation, problems that arose during the operation were recorded and all patients were interviewed on the first postoperative day. One hundred and seven patients were interviewed after being discharged, 1-3 months after the operation. No major complications occurred. Two male patients experienced postdural puncture headache. Nausea (33% vs 10%), micturition difficulties (27% vs 12%), tenderness at the side of the iv-cannula (21% vs 10%) and sore throat (29% vs 0%) were more common after balanced general anaesthesia than after spinal anaesthesia. Sensory disturbances (10% vs 1%) occurred more frequently after spinal anaesthesia. All these problems had ceased at the interview 1-3 months later. Eight (six spinal and two general anaesthesia patients) were not satisfied with the method of anaesthesia used. This study revealed that an appreciable number of young patients have complications after anaesthesia, but the complications are minor and self-limited.

Twenty-one percent of 500 unselected patients, aged 17 to 50 years, seeking primary care for any reason were found to be suffering from a chronic fatigue syndrome consistent with "chronic active Epstein-Barr virus (EBV) infection," They had been experiencing "severe" fatigue, usually cyclic, for a median of 16 months (range, six to 458 months), associated with sore throat, myalgias, or headaches; 45% of the patients were periodically bedridden; and 25% to 73% reported recurrent cervical adenopathy, paresthesias, arthralgias, and difficulty in concentrating or sleeping. The patients had no recognized chronic "physical" illness and were not receiving psychiatric care. While antibody titers to several EBV-specific antigens were higher in patients than in age- and sex-matched controls subjects, the differences generally were not statistically significant. A chronic fatigue syndrome consistent with the chronic active EBV infection syndrome was prevalent in our primary care practice. However, our data offer no evidence that EBV is causally related to the syndrome. Indeed, we feel that among unselected patients seen in a general medical practice currently available EBV serologic test results must be interpreted with great caution.

In July 1982, an outbreak of pharyngitis caused by adenovirus type 7a occurred among children in a small town in western Oklahoma. Predominant symptoms were fever and sore throat (by case definition), headache (83%), abdominal pain (64%), and conjunctivitis (51%). At least 77 persons were identified whose symptoms met the case definition for illness. Onsets of illness peaked during the week of July 5 to 12, and the outbreak resolved within three weeks. A systematic telephone survey of the town revealed that persons who had swum at the community swimming pool were more likely to be ill than those who had not (P less than .001). A second survey of families with season passes to the pool showed that among swimmers, illness was directly related to average number of hours of exposure to the pool each week (P less than .001 by chi-square for trend). In addition, swimmers who reported swallowing pool water were more likely to be ill (29 of 56, 52%) than persons who did not (ten of 41, 24%) (P = .01). Throat-swab specimens from five of seven ill persons (71%) grew adenovirus 7a compared with one of 12 well persons (8%) (P = .01). The pool chlorinator had reportedly malfunctioned during early July. The outbreak resolved with proper operation of the chlorination system. Swimming pools continue to be a potential source of community-wide outbreaks of adenovirus infections.

The results of a prospective randomised evaluation of general anaesthesia (GA), epidural anaesthesia (EA) and spinal anaesthesia (SA) for extracorporeal shockwave lithotripsy are presented. GA provided speed and reliability but resulted in a high incidence of postoperative nausea, vomiting and sore throat. Both regional techniques conferred the advantages of an awake, cooperative patient, but EA required a longer preparation time than SA and more supplementary treatment with fentanyl or midazolam. A major drawback associated with the use of SA was a 42% incidence of postspinal headache. All three techniques were associated with hypotension on placement in the hoisl; bath immersion resulted in significant rises in blood pressure in the EA and SA groups and a more variable (overall non-significant) response in the GA group.

This paper describes the few case reports of neurological effects of acute (primary) HIV infection. Following a typical primary illness (fever, sore throat, headache, rash, lymphadenopathy, superficial oral ulcers, conjunctivitis, leukopenia and thrombocytopenia) aseptic meningitis, myelopathy, spinal myoclonus, peripheral or cranial neuropathy, neuralgia and ganglioneuronitis may occur, usually within 3 weeks. Encephalopathy with spontaneous recovery also occurs, usually without other features of acute HIV infection. Diagnosis depends on demonstration of seroconversion which may be delayed by weeks. No therapy is yet available.

The clinical symptoms and signs were assessed in 20 consecutive patients developing infection with the human immunodeficiency virus (HIV). All were male homosexuals and all presented with a glandular-fever-like illness. Changes in laboratory values were compared with findings in 40 HIV negative male homosexual controls. In the 10 patients for whom date of exposure to the virus could be established the incubation period was 11-28 days (median 14). One or two days after the sudden onset of fever patients developed sore throat, lymphadenopathy, rash, lethargy, coated tongue, tonsillar hypertrophy, dry cough, headache, myalgia, conjunctivitis, vomiting, night sweats, nausea, diarrhoea, and palatal enanthema. Twelve patients had painful, shallow ulcers in the mouth or on the genitals or anus or as manifested by oesophageal symptoms; these ulcers may have been the site of entry of the virus. During the first week after the onset of symptoms mild leucopenia, thrombocytopenia, and increased numbers of banded neutrophils were detected (p less than 0.0005). The mean duration of acute illness was 12.7 days (range 5-44). All patients remained healthy during a mean follow up period of 2.5 years. Heightened awareness of the typical clinical picture in patients developing primary HIV infection will alert the physician at an early stage and so aid prompt diagnosis and help contain the epidemic spread of AIDS.
