Serums obtained from patients during acute exacerbations of multiple sclerosis produce a reversible depression of polysynaptic reflex responses when applied to the isolated spinal cord of the frog. Motoneuron discharges initiated by monosynaptic activation through an axosomatic spinal pathway are much less affected than reflex discharges. The active factor in serum appears to depend on the presence of complement.

Compared to normal and other neurological disease (OND) controls, multiple sclerosis (MS) pre nylon wool (pre NW) and nylon wool passed (NWP)-peripheral blood cells' natural killer (NK) activity was more sensitive to prostaglandin E (PGE1); it was suppressed to a greater degree and at lower concentrations of PGE1. At the single cell level this was reflected by lower numbers of target-binding cells (TBCs) and fewer killers among the TBCs. ONDs and normal controls were equally sensitive to PGE1. Though PGE-producing cells were depleted in the NWP population of normal and control ONDs, MS patients still had indomethacin-sensitive NK suppressors in the NWP population; these apparently did not suppress at the single cell effector level but at the level of recycling. MS and OND cerebrospinal fluid (CSF) cells' NK activity could not be 'enhanced' by indomethacin. Depression of interferon (IFN)-induced NK by PGE1 was greater in MS than in OND or normal controls perhaps through its effect on IFN-induced recycling. All subjects' cells maintained sensitivity to PGE1 after overnight incubation in the presence of PGE-producing cells (pre NW) or exogenous PGE1. In sharp contrast to normal and OND controls, MS NWP cells were still inhibited by PGE1 even after overnight incubation in the absence of PGE1.

Degree of depression found in 120 spinal multiple sclerosis (MS) outpatients was related significantly to selected illness, demographic, and social variables. The more depressed individuals tended to be more disabled, older, and, in particular, perceived their families and friends as providing less social support than those who were less depressed. Those who had experienced at least one remission were less depressed than those who never had had a remission. Contrary to hypothesized expectations, the results also suggested that the longer a patient has MS, the more depressed he will be. Such results raise implications for psychotherapeutic intervention in this population, as well as suggest the need for future investigations of the MS patient's body image, self-concept, and perception of disability.

Cognitive involvement in multiple sclerosis has not been given adequate clinical attention. Many patients have behavioral problems which may be ascribed superficially to depression or inability to cope. Cognitive assessment as conducted in most neurological examinations may be rated as normal. However, neuropsychological testing on these patients frequently reveals impairment of cognition. These findings merit followup to provide clearer directives for clinical interventions.

Thirty multiple sclerosis patients were assessed: 15 with predominantly cerebral involvement of their demyelinating disease and 15 with predominantly spinal cord and cerebellar involvement. The groups were matched with regard to age, duration of illness, and Kurtzke disability scores. Assessment included neuropsychological testing, the Beck Depression Inventory, and a psychiatric interview patterned after the Schedule for Affective Disorders and Schizophrenia. A group of normal volunteers served as controls for the neuropsychological testing. There were significantly more major depressive episodes in the cerebral group, as assessed by the patients' histories and by interview, and there was a trend toward more depressive symptoms in this group, as measured by the Beck inventory.

A questionnaire study on sexual problems occurring with multiple sclerosis (MS) was carried out with 217 patients who had previously participated in the University of Washington Multiple Sclerosis Project. More than one-half of the participating subjects were ambulatory without aids and nearly 75% did not use a wheelchair. Sexual dysfunction was reported by 56% of the women and 75% of the men. Among the women, the most commonly occurring sexual symptoms (in decreasing order of frequency) were fatigue, decreased sensation, decreased libido, decreased frequency or loss of orgasm and difficulty with arousal. Men reported the most common problem was erectile dysfunction, followed by decreased sensation, fatigue, decreased libido, and orgasmic dysfunction. Although loss of mobility, weakness and depression are not significantly associated with sexual dysfunction, spasticity and bladder dysfunction appear to be associated. However, even where these symptoms were absent, sexual dysfunction was perceived in at least 50% of the cases. The data indicate that sexual dysfunction can be anticipated in at least 50% of the women and about 75% of the men affected by MS, regardless of mobility level. It is most likely to occur in patients with spasticity and bladder dysfunction.

The prevalence and nature of emotional disturbance in patients with multiple sclerosis (MS) was studied prospectively in 64 MS patients and 23 spinal cord-injured (SCI) control patients by administration of the 28-item subscale General Health Questionnaire (GHQ). MS patients in remission had a mean GHQ score of 4.4, and patients with acute exacerbation or progressive nonremitting MS had a mean score of 15.7, a significant difference (p less than 0.001). The prevalence of emotional disturbance was 90% in exacerbating or progressing patients, 39% in stable patients, and 12% in SCI control patients. The presence of emotional disturbance was not related to age, sex, or other demographic variables, to duration or severity of disease, or to the degree of disability. In the group of MS patients in remission, somatic complaints, anxiety, and social dysfunction were more prevalent than symptoms of depression.

There is little absolute data in the form of prospective studies in patients with specific illnesses who are on oral contraceptives (OCs). Consequently, the clinician must depend on well-founded empiric decisions in prescribing the pill for these patients. The basis for the decision should be a firm understanding of the pathophysiology and laboratory effects of OCs. This needs to be juxtaposed with an understanding of the efficacy and effects of the estrogen and progestational components of the birth control pill and their interactions with maintenance medications. Available evidence is reviewed for the following medical disorders: central nervous system disorders (depression, Wilson's disease, headaches, epilepsy, multiple sclerosis, and the eye); immunologic and connective tissue diseases; diseases of the endocrine system, the gastrointestinal system, the genitourinary system, the memopoietic system; and skin disorders. 7% of women on OCs have increased or newly reported depression. Whether these are primarily psychogenic or metabolically derived is yet to be definitively determined. Wilson's disease can be exacerbated by OCs because of increased plasma ceruloplasmin and increased absorption of copper from the gastrointestinal tract. Headaches can be either a vague or a specific symptom, such as migraines, but 1/3 of these patients will become worse on OCs. There is good evidence that the headaches are caused by falling estrogen levels. There is no good evidence that epilepsy, in general, becomes worse on OCs. OCs have relatively no effect on the longterm prognosis in multiple sclerosis. Increased corneal sensitivity has been observed with OC use, and this has usually presented an intolerance to the use of contact lenses. This is primarily the result of increased edema of the cornea and changing of its contour. By inference, OCs cause some basic universal changes in the immunologic system. OCs have been reported as a cause of a rare form of rheumatoid arthritis, but the Royal College reports a decrease in incidence of cell-mediated immunologic disease, specifically rheumatoid arthritis in its more familiar form. There is no evidence that OCs markedly influence thyroid disease, but they do markedly alter thyroid function testing. OCs do not produce a chronic addisonian state nor do they inhibit the ability of the adrenal-pituitary axis to respond to stress. OCs can be used in thyroid disease but with some caution in hypothyroid states. They should not be used in patients with Cushing's syndrome and are not recommended in patients with adenomas. In general, estrogen works as an irritant to the gastric mucosa, but there is no increase in peptic ulcer diseases associated with OC use, and the incidence of duodenal ulcer disease is decreased. The most striking liver disease seen with OCs is cholelithiasis. The incidence is increased 2-fold. OCs should not be prescribed for patients with chronic renal disease because of the vascular effects as well as the reported increased risk of urinary tract infection. The Royal College report has shown a decreased incidence of iron deficiency anemia in patients on OCs. Various skin changes have been reported in women using OCs. The most common of these is chloasma. In all the diseases studied thus far, the use of OCs has not precipitated a catastrophic change.

It is stimulating to ascertain the comparative risk to the woman of hormonal contraceptives of the various kinds used today: combination preparations, which rely on blocking the secretion of gonadotropic hormones by the hypothesis; sequential preparations, which rearrange the physiological relationships of the menstrual cycle; gestagen preparations (minipills), which heighten the viscosity of the cervical mucus; longterm injectable preparations, which initially block ovulation and then act on the cervical mucus; postcoital preparations, which act by inducing abortion of the fertilized egg. Of these the most reliable are the fixed combinations, while sequential preparations are somewhat less so. The minipills are the least reliable. Interaction with other medications can reduce the reliability of these preparations; for instance, women on contraceptives have become pregnant after taking antiepileptic medications containing phenobarbitol and hydantoin. As far as risk is concerned, we must distinguish between those that merely harm the woman and those that pose a threat to life. Some of the former are: bleeding between cycles, failure of menses to appear after cessation of contraception, depression, breast-pains, hypertension, thrombophlebitis, and reduced libido. Hormonal contraceptives also have a series of beneficial effects, especially in women who ordinarily have menstrual difficulties. Among the more serious side effects are: risk of teratogenicity, carcinogenicity, liver problems, thromboses, and infarctions. To reduce the risks of these various side effects, the physician should observe carefully the contraindications: these are both absolute (cerebrovascular and retinal problems, thrombo-embolisms, hepatic disease, diabetes, porphyria, and sickle-cell anemia and relative (migraines, cardiac pains, hyperlipemia, epilepsy, and multiple sclerosis).

Twenty-seven Japanese patients with multiple sclerosis (MS) were studied by recording the spinal and cortical somatosensory evoked potentials (SEPs) in response to median nerve and/or posterior tibial nerve stimulation. The median nerve SEPs were abnormal in half the cases whereas the tibial nerve SEPs were abnormal in 90% of cases. SEP abnormalities, especially absence or amplitude depression of components, were highly correlated with proprioceptive impairment of hands or legs tested. With regard to the usefulness of SEP in detecting subclinical lesions of the sensory system, the tibial nerve SEP was found more useful than the median nerve SEP. Absence or depressed amplitude of SEP components was seen more commonly with tibial nerve stimulation as compared with median nerve stimulation.
