A clinical trial was conducted to determine the tolerance and toxicity of recombinant tumor necrosis factor (rTNF) and recombinant interferon gamma (rIFN-gamma) when administered concurrently by continuous intravenous infusion to 11 patients with the AIDS-related complex (ARC). In addition, HIV culture, p24 antigen levels, and CD4 positive lymphocytes were monitored to obtain preliminary evidence of antiviral and immunologic effects. Two 5-day treatment cycles were separated by a 9-day washout period. Two patients were entered at each dosage level and each patient received the two 5-day treatment cycles at two sequential dose levels ranging from 1 to 25 micrograms/m2. Two patients did not complete their second treatment cycle--one due to the development of a rash, the second due to central venous catheter
discomfort
. The occurrence of phlebitis with peripheral vein administration of these agents necessitated administration via central venous catheter. With the exception of a single patient who developed severe
headache
at the 25 micrograms/m2 dose, severe clinical toxicities were not observed. Fever, chills,
headache
, and myalgias were the most significant clinical toxicities observed and all were dose dependent. The percentage fall in total granulocytes was dose dependent and ranged from 17% at the 1 microgram/mm2 dose to 48% at both the 15 and 25 micrograms/mm2 dose levels. The mean nadir granulocyte count was 1694/mm3. No significant renal or hepatic toxicity was observed. Of 22 treatment cycles the CD4 cell number was increased in 11, unchanged in 7, and decreased in 4. The mean CD4 cell number did not change significantly (176 +/- 143/mm3 pretherapy versus 279 +/- 305/mm3 posttherapy).(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship of electromyographic (EMG) and temporal artery vasomotor activity to MMPI subgroups was examined in 60 chronic
headache
sufferers. Analysis of the right frontalis data revealed a significant interaction between MMPI subgroup and position (reclining, sitting, standing) with a trend toward the same interaction with the left frontalis. However, this effect was only found when the contemporary MMPI norms were utilized in the formation of the subgroups. No effects were found for the bilateral trapezius EMG or bilateral temporal artery sites. Analysis of the self report data revealed a significant main effect for the Total Pain Score of the Pain Mannequin but not for a current
headache
intensity rating. Again, the former effect was seen most clearly when the contemporary MMPI norms were used. In general, these data support a Psychological
Distress
Hypothesis in that patients with significant elevations (greater than 70) demonstrated greater frontalis EMG activity and higher Pain Mannequin scores. Additionally, the data demonstrate the importance of utilizing the contemporary MMPI norms in the formation of subgroups.

Formaldehyde (HCHO) is a common chemical found in occupational and residential environments and has been suggested as a cause of asthmalike symptoms in some individuals. Clinical and animal studies suggest that HCHO adsorbed on respirable particles may elicit a greater pulmonary physiologic and inflammatory effect than gaseous HCHO alone. The purpose of this study was to determine if respirable carbon particles have a synergistic effect on the acute symptomatic and pulmonary physiologic response to HCHO inhalation. We randomly exposed 24 normal, nonsmoking, methacholine-nonreactive subjects to 2 h each of clean air, 3 ppm formaldehyde, 0.5 mg/m3 respirable activated carbon aerosol, and the combination of 3 ppm formaldehyde plus activated carbon aerosol. The subjects engaged in intermittent heavy bicycle exercise (VE = 57 l/min) for 15 min each half hour. Measures of response included symptom questionnaires, spirometry, body plethysmography, and postexposure serial peak flows. Formaldehyde exposure was associated with significant increases in reported eye irritation, nasal irritation, throat irritation,
headache
, chest
discomfort
, and odor. We observed synergistic increases in cough, but not in other irritant respiratory tract symptoms, with inhalation of formaldehyde and carbon. Small (less than 5%) synergistic decreases in FVC and FEV3 were also seen. We observed no HCHO effect on FEV1; however, we did observe small (less than 10%) significant decreases in FEF25-75% and SGaw which may be indicative of increased airway tone. Overall, our results demonstrated synergism, but the effect is small and its clinical significance is uncertain.

The in vivo effect of yeast-derived recombinant human granulocyte-macrophage colony-stimulating factor (rh GM-CSF) was investigated in 30 patients with advanced malignancy in a phase Ib trial. Patients were treated at four different dose levels (120 to 1,000 micrograms/m2/d) by either daily intravenous (IV) bolus injection or 24-hour continuous infusion. Administration of rh GM-CSF resulted in a broad spectrum of dose- and schedule-dependent hematopoietic effects. Sustained infusion of rh GM-CSF elicited a maximum 17-fold average peak increase of the total WBC count with mainly neutrophils, eosinophils, and monocytes accounting for this rise, and increases in bone marrow cellularity with a shift to immature myeloid elements. Elevation of lymphocytes, platelets, and reticulocytes was not induced. Within five days after discontinuation of treatment the leukocytosis had disappeared. Adverse reactions encountered with rh GM-CSF seen in 65% of the patients studied were never life-threatening and always rapidly reversible. They included mild myalgias, facial flushing, low-grade fever,
headache
, bone
discomfort
, nausea, dyspnea, and transient decline of platelet counts. These results suggest that rh GM-CSF can be safely administered at the doses and schedules used and that it can induce in vivo some of the biological effects reported in in vitro studies. Although no objective antitumour responses have been seen, the ability of rh GM-CSF to increase number and function of leukocytes in vivo may prevent neutropenia and infections when GM-CSF is added to cytotoxic cancer therapy.

Erythema migrans is the distinctive cutaneous marker of Lyme borreliosis. The clinical picture is variable but at some point in its evolution, erythema migrans presents as a red, centrifugally expanding, annular plaque. Erythema migrans may appear as a solitary lesion or in multiplicity. It may be accompanied by extra cutaneous signs and symptoms as fever,
headache
, musculoskeletal
discomfort
, and regional lymphadenopathy. The diagnosis of erythema migrans is based primarily on clinical findings because serologic tests to detect elevated antibody levels to Borrelia burgdorferi are frequently negative during the first few weeks of the illness. Identification of Borrelia burgdorferi from skin biopsy specimens obtained from erythema migrans lesions microbiologically or histopathologically will confirm the clinical diagnosis of erythema migrans.

54 outpatients who were referred with the clinical diagnosis lumbar disk herniation, underwent lumbar myelography with iohexol. After the examination the patient returned to the ward where he was observed for about 2 hours while resting in a chair. He was then allowed to leave the hospital with the recommendation to avoid hard physical exercise for the next 24 hours. No serious complications occurred. Severe
headache
was reported by 20% of the patients and 22% experienced transient minor
discomfort
. It is concluded that lumbar iohexol myelography can be performed safely on ambulatory patients.

A 46-year-old man was hospitalized with paroxysmal
headache
and chest
discomfort
. His blood pressure varied, occasionally being up to 300/160 mmHg. Cardiac examination revealed a decrescendo type of diastolic murmur (aortic regurgitation) and S4 gallop. Both blood and urine catecholamine levels were extremely high. Electrocardiogram and echocardiogram showed severe left ventricular hypertrophy pattern presenting hypertrophic cardiomyopathic changes. The phonocardiogram showed marked Hegglin syndrome (QT; 450 msec and QII; 310 msec). Right adrenal tumor, pheochromocytoma was found on the abdominal CT scanning and 131I-metaiodobenzylguanidine (MIBG). In the post-operative period, Hegglin syndrome was completely abolished (QT; 360 msec and QII; 345 msec,), and also electrocardiographic left ventricular hypertrophy pattern improved immediately after surgical removal of the pheochromocytoma.

Twenty-four women employed as computer operators were evaluated for complaints of occipital
headaches
, as well as neck and shoulder pain. Although the symptoms were highly variable with respect to duration, intensity and distribution, they were mutually consistent in that they started or intensified with the resumption of the work week. The patients varied in age from 25 to 58 with a median average of 48 years. Fifteen demonstrated radiographic evidence of cervical degenerative disc disease and in an additional four, electromyographic evidence of cervical root compromise was present. Multiple precipitating factors were identified in Monday's
headache
including the predisposing presence of unrecognized impairment of visual acuity in 4 and cervical radiculopathy in 16. Mechanically, prolonged postural cervical hyperextension frequently combined with repetitive head rotation appeared to trigger the
discomfort
complaints. Undue elevation of the CRT screen, prolonged copying of laterally displaced hard copy, the wearing of bifocals, as well as seating either excessively soft or with a tendency to pitch the operator forward were identified as additional aggravating factors.

We investigated stripe-induced visual
discomfort
and its relation to migraine. Some people find viewing striped patterns aversive. Prior work has suggested that migraineurs, in particular, are bothered by stripes. Subjects were selected by opportunity sampling. They were shown striped patterns and asked questions about their general health and their
headache
history, if any. Of the 102 subjects, 38 were diagnosed as having migraine headaches, 22 had nonmigraine
headaches
, and 42 were considered to be nonheadache subjects; 82% of those with migraines were stripe sensitive while only 6.2% without migraines were stripe sensitive. We conclude that stripe aversiveness is related to migraine headaches and can assist differentiation of migraine and nonmigraine
headaches
.

Sixty-eight medical, social, and occupational history variables were analyzed in a general population of 442 men and 478 women, aged 30, 40, 50, and 60 years to identify possible indicators for first-time experience and recurrence or persistence of low-back trouble (LBT) during a 1-year follow-up. Variables that in univariate analyses showed statistically significant indications for future LBT were subjected to stepwise logistic regression analyses. The most important indicators for recurrence or persistence of LBT thus identified were, for men, intermittent claudication, restlessness, or other
discomfort
in the lower limbs, frequent
headache
, and living alone. For women, the corresponding indicators were rumbling of "the stomach" and feeling of fatigue. For first-time experience of LBT, the indicators identified by the regression analyses were frequent pain in the top of the stomach, previous hospitalizations and operations, daily smoking, and a long distance from home to work. The result suggests that the population likely to experience future LBT does not enjoy good general health even prior to its first LBT episode, and this, in turn, may be due to greater psychosocial pressure.
