Varying reactions of the vegetative nerve system to various point combinations (for example: vomiting, dizziness, diarrhea, urge to urinate, fatigue or drowsiness, headache), especially to the needling of Tai Chong (Li 3), induced us to perform biochemical studies before and after acupuncture treatment. A group of children and a group of adults were studied. The material studied was urine and blood; from the children, urine only. The following were determined in the urine: indolacetic acid, 5-hydroxy-indol-3-acetic acid, homovanillic acid, and vanillic-mandelic acid; in the blood, tyrosine and tryptophan (free and bound). Individual points with wide influence (He Gu = LI 4; Zu San Li = St 36; Tai Chong = Li 3) and their combination with generally effective points were tested. The needling of Tai Chong especially showed a clear increase in indolamine metabolism. Isolated increases in metabolites of catecholamine metabolism could be correlated with the patient's increased physical activity after acupuncture. Noteworthy is the observation that no significant chemical reactions were evident if local reactions to the needling no longer appeared at the end of a series of acupuncture treatments.

Patients with erythema multiforme (EM) often have chronic or recurring oral lesions that cause intense pain and interfere with a variety of functions including eating and speech. Previous studies suggest that levamisole restores to normal the function of phagocytes and T lymphocytes, and activates the inflammatory response. In our previous double-blind study 8 of 13 patients with EM had a decrease in severity and frequency of attacks. The purpose of this open prospective study was to evaluate short-term and long-term clinical efficacy of levamisole in patients with mucocutaneous EM. Thirty-nine patients with mucocutaneous EM seen in the Oral Medicine Clinic, School of Dentistry, University of California-San Francisco, comprised our study group. Levamisole was used alone in 17 patients or in combination with prednisone in 22 patients and was given as a single dose of 150 mg/day for 3 consecutive days. Thirty-one patients showed a complete response from levamisole (alone in 13 and in combination with prednisone in 18). Four showed a partial response of signs and symptoms, and four others had no benefits from levamisole whether alone or in combination. The most common side effects from levamisole were skin rash, tiredness, weakness, myalgia, taste change, and insomnia.

Beta-blockade therapy to improve survival in idiopathic dilated cardiomyopathy (IDC) has been both advocated and criticized. However, randomized studies have not been performed. Thus, 50 patients with IDC were randomized in pairs to standard therapy (C) alone or with beta blockade (BB). Beta-blockade therapy with metoprolol was titrated from 12.5 to 50 mg twice daily as tolerated (final average dose, 61 mg/day). Groups were comparable in age (C, 50 +/- 15 years; BB, 51 +/- 13 years), gender (C, 76% male; BB, 56% male), entry functional class (C, 2.8 +/- 0.8; BB, 2.7 +/- 0.7), and left ventricular ejection fraction (C, 27 +/- 12%; BB, 29 +/- 10%). Follow-up averaged 19 months (range 1 to 38). One subject in each group was lost to follow-up. There were 3 early BB dropouts (within 2 days) due to low-output syndrome (2 patients) or fatigue (1 patient). Eleven patients died. By intention to treat, 5 BB and 6 C patients died (difference not significant). By actual treatment, 3 BB patients died, including 2 late dropouts (at 0.2, 10 and 17 months), and 8 C patients died (at 2, 9, 9, 15, 18, 24, 29 and 32 months, p = 0.12). In additional, functional evaluation on follow-up (functional class, San Diego questionnaire and exercise time) all tended to favor those receiving BB. Low-dose BB is tolerated in 80% of IDC patients on a long-term basis. Those continuing to take BB have a good prognosis. Mortality in C patients, however, is less than in some retrospective studies.(ABSTRACT TRUNCATED AT 250 WORDS)

The incidence of acute mountain sickness was determined by questionnaire in 454 individuals who attended week-long continuing medical education programs at ski resorts in the Rocky Mountains with base elevations of about 2000 m. As a control group, 96 individuals who attended continuing medical education programs at sea level in San Francisco completed similar questionnaires. Study subjects were classified as having acute mountain sickness when they reported three or more of the five possible cardinal symptoms: headache, insomnia, dyspnea, anorexia, and fatigue. Only symptoms with an intensity of at least grade 2 (moderate) out of 5 were analyzed. Acute mountain sickness-like symptoms occurred in 25% of subjects at 2000 m compared with 5% of subjects at sea level. The incidence of acute mountain sickness at 2000 m was greatest among subjects who had come from lower altitudes. Half of the subjects with symptoms took medication. The duration of symptoms was short, with 90% of all symptoms that were reported occurring in the first 72 hours. Acute mountain sickness is common at intermediate altitudes, and it is frequently severe enough to prompt self-medication.

Reported single car and truck accidents due specifically to driver 'fatigue' for the 4-year span of 1980-1983 were analyzed for 24-hr, 7-d and 1-yr patterns. Three types of data were examined: (1) accidents in rural Texas, (2) accidents only in San Antonio, the fourth largest city in Texas and (3) accident ratio (number of accidents per time interval divided by traffic volume for the interval) in this city. A statistically significant seasonal variation of relatively low amplitude with peaks in May and July was detected only for accidents in rural areas. High-amplitude periodicities of 7 d were evident in all the data sets, with a peak on the weekend. A very prominent 24-hr pattern was detected as well, with the acrophase determined by single cosinor around 0300. A slight secondary peak in accidents, around 1500, was evident in the data from the rural areas. This secondary peak represented a 12-hr rhythm in addition to the 24-hr. Overall, features of the temporal patterns in accidents over 24 hr and over the year in urban and rural areas differed only slightly. Accident ratios yielded results similar to accident frequencies. However, with regard to the rural data, the shape of the 24-hr temporal pattern varied with driver age; older drivers exhibited a flatter curve with a more pronounced afternoon rather than early morning (around 0300) peak.

This paper presents a case in which treatment of acquired immunodeficiency syndrome (AIDS) was attempted with thymic humoral factor (THF). The capacity of THF for immunoenhancement and modulation of the immune response has been demonstrated in other conditions. The patient, a 24-year old black male homosexual from San Francisco, had experienced fever spikes, malaise, fatigue, anorexia, gradual vision loss, and weight loss over an 8-month period. Lymphopenia, T cell deficiencies, and imbalances in T cell subpopulations established the diagnosis of AIDS. Treatment with arabinoside A and fibroblast interferon was not effective. THF was then administered by daily injections for 3 weeks. At the end of the 2nd week of treatment, increased alertness and appetite were noted. Also documented was a transient increase in circulating lymphocytes, T cells, and helper cells. However, at the end of the 3rd week, the patient developed bronchopneumonia followed by renal failure and died in an acute encephalopathic state. Only 1 other (unsuccessful) attempt to treat an advanced case of AIDS with a thymic hormone has been reported. It is suggested that THF treatment might be more effective if offered at a very early stage of AIDS. It is hypothesized that a sufficient pool of precursor T cells is required to serve as target cells for immune modifiers such as THF. This precursor pool probably shrinks beyond rescue in the advanced stages of AIDS. The authors are currently involved in trials of immunomodulation with THF at early stages of immune impairment in pre-AIDS patients.

This paper considers medical care given by physicians to men and women in the United States. It asks how often significant sex differences in care occur, and if these differences are attributable to medically relevant factors or not. Sex differences in diagnostic services, therapeutic services, and dispositions for follow-up are studied for All Visits, 15 major groups of complaints, and 5 specific complaints (fatigue, headache, vertigo/dizziness, chest pain, and back pain). Data are from the 1975 National Ambulatory Medical Care Survey (NAMCS). The analysis reveals that medical care is often similar for men and women, but a sizable numbers of significant sex differences occur (about 30 to 40 per cent of the services and dispositions studied), and they tend to show more medical care for women. Most of the differences persist even after controlling for medically relevant factors (patient age, seriousness of problem, diagnosis, prior visit status, and reasons for visit). Notably, women still receive more total prescriptions, and return appointments for many complaint groups. They receive more services for back pain and headaches and more follow-up plans for vertigo/dizziness and back pain. Remaining sex differences may be due to missing medical factors, patient requests for care, patient distress and needs for nurturance, and physician sex bias. In contrast to a recent San Diego study, national data show few significant sex differences in the extent and content of diagnostic services given for five common complaints.

Obstructive sleep apnea syndrome (OSAS) was diagnosed in157 subjects based on clinical symptoms, physical evaluation, cephalometric x-ray films, and polysomnography. These index cases identified 844 living first-degree relatives. Mailings were sent to 792 (94%). The mailing consisted of two identical questionnaires, one for the family member of the index case and one to be given to a friend (not a relative) of approximately the same age. In response, we received 531 (63%) questionnaires from relatives and 198 (25%) questionnaires from age-matched nonrelated friends, which were used as a control group. A more extensive investigation was performed on first-degree relatives of the index group living in the San Francisco Bay Area or vicinity. Two hundred seventy-nine relatives (100%) were identified. One hundred sixty-six subjects (59%) as well as 69 age-matched friends (ie, 41% of the 166 relatives and 25% of the potential total group) agreed to participate in further studies. These subjects had interviews, clinical investigations, and nonattended ambulatory monitoring. Cephalometric x-ray films could be obtained on only 22 of 166 participating relatives and 6 of 69 friends. Body mass index was not a differentiating measure between relatives and friends. Odds ratios (ORs) were calculated from the questionnaiare data. The report of tiredness, fatigue, and sleepiness did not distinguish family members from friends. The OR, however, progressively increases when there is a positive history of near nightly loud snoring (OR = 1.78; 95% confidence interval [CI] 1.25-2.54) or a positive history of daytime sleepiness in conjunction with near nightly loud snoring (OR = 3.11; 95% CI = 1.94-4.99). The investigation in the Bay Area indicated that, when first-degree relatives were compared with friends, the complaint of daytime tiredness, sleepiness, or both with the presence of a high and narrow(ogival) hard palate sharply differentiated between friends and relatives (OR = 10.9, 95, CI = 5.31-22.5). An Epworth Sleepiness Scale score of 9 or greater with the presence of another symptom associated with OSAS, and a respiratory disturbance index greater than 5 (number of apneas and hypopneas per hour of sleep > 5) gave an OR of 45.6 (95% CI = 18.8-11.0). Disproportionate craniofacial anatomy was common in familial groups with OSAS. Craniofacial familial features can be a strong indicator of risk for the development of OSAS.

After stimulation of the bilateral phrenic nerves of the rabbits, the effect of Shengmai San (SMS) on their normal function and the diaphragmatic fatigue was observed with the measuring of diaphragm evoked potential (DEP), and the analysis of the power spectrum of diaphragmatic electromyogram (EMGdi) at spontaneous breathing. The results were as follows: (1) After the administration of 2 ml/kg of SMS, amplitude of DEP, central frequency, and the high/low frequency ratio were markedly increased. (2) Injecting SMS in 2 ml/kg in 30 minutes before injury could protect significantly against diaphragmatic fatigue following electrical stimulation of the phrenic nerves. (3) Injecting SMS in 2 ml/kg after fatigue could enhance the recovery of the diaphragmatic fatigue.

The objective of this study was to identify factors explaining the correlations among unexplained severe fatigue of different durations (1-5 months or > or =6 months) and symptoms reported as being significant health problems during a preceding 4-week period. Between June and December of 1994, a cross-sectional, random digit dialing telephone survey was conducted among residents of San Francisco, California. All subjects who reported having severe fatigue lasting for > or =1 month and a random sample of nonfatigued subjects were asked to participate in a detailed telephone interview. Data from 1,510 individuals aged 18-60 years who did not have medical or psychiatric conditions that could explain their severe fatigue were analyzed. Common factor analyses identified three correlated factors (defined as "fatigue-mood-cognition" symptoms, "flu-type" symptoms, and "visual impairment") that explained the correlations among fatigue lasting for > or =6 months and 14 interrelated symptoms. No factor explained the correlations among fatigue lasting for 1-5 months and other symptoms. The combination of fatigue of > or =6 months' duration and selected symptoms overlaps with published criteria used to define cases of chronic fatigue syndrome (CFS). Although symptoms described in this study were reported as appearing within the preceding month, and CFS symptoms must have been present for the previous 6 months, these results provide empirical support for the interrelations among unexplained fatigue of > or =6 months' duration and symptoms included in the CFS case definition.
