Between 20 July and 15 Octoboer 1975, five cases of human infection with Babesia microti were diagnosed on Nantucket Island, Massachusetts. The illness was characterized by fever, drenching sweats, shaking chills, myalgia, arthralgia, extreme fatigue, and a mild-to-moderate hemolytic anemia. None of the patients had a history of splenetomy. Although all patients responded symptomatically to treatment with oral chloroquine phosphate, parasitemia and fatigue frequently persisted for several weeks to months.

Between 1985 and 1990, the authors performed stereotactic posteroventral pallidotomies on 38 patients with Parkinson's disease whose main complaint was hypokinesia. Upon re-examination 2 to 71 months after surgery (mean 28 months), complete or almost complete relief of rigidity and hypokinesia was observed in 92% of the patients. Of the 32 patients who before surgery also suffered from tremor, 26 (81%) had complete or almost complete relief of tremor. The L-dopa-induced dyskinesias and muscle pain had greatly improved or disappeared in most patients, and gait and speech volume also showed remarkable improvement. Complications were observed in seven patients: six had a permanent partial homonymous hemianopsia (one also had transient dysphasia and facial weakness) and one developed transitory hemiparesis 1 week after pallidotomy. The results presented here confirm the 1960 findings of Svennilson, et al., that parkinsonian tremor, rigidity, and hypokinesia can be effectively abolished by posteroventral pallidotomy, an approach developed in 1956 and 1957 by Lars Leksell. The positive effect of posteroventral pallidotomy is believed to be based on the interruption of some striopallidal or subthalamopallidal pathways, which results in disinhibition of medial pallidal activity necessary for movement control.

According to the hypothesis that the development of physical dependence on and tolerance to opiates depends on the inhibition by opiates of L-asparaginase and L-glutaminase activities in the brain, and the blockade by opiates of the aspartatergic/glutamatergic receptors especially NMDA, four female and fourty-four male heroin addicts were included in a double-blind clinical trial. Four mg chlorpromazine (CPZ) was administered every hour and 10 mg diazepam (DIA) every 6 hours to a group consisting of two female and nineteen male inpatients. The remaining subjects received 15 mg non-opioid antitussive dextromethorphan (DM) instead of CPZ. The withdrawn addicts were controlled twice a day and yawning, lacrimation, rhinorrhoea, perspiration, goose flesh, muscle tremor, dilated pupils, anorexia, joint and muscle aches, restlessness, insomnia, emesis, diarrhea, craving and rejection of smoking as abstinence syndrome signs were observed and rated on a scale of 1, 2 and 3 points according to their intensity. All signs, except perspiration and emesis, were significantly less intense in the group given DM + DIA than CPZ + DIA. The other plus points included the immediate stop of craving and the early onset of smoking in DM + DIA group. The results are considered to be supporting evidence for the hypothesis emphasizing the blockade of NMDA receptors by opiates in opiate addiction. Furthermore, the decrease caused by non-opioid NMDA antagonists in the responsiveness of NMDA receptors appears very promising for the treatment of opiate addicts.

Persons with Q fever usually present with severe retrobulbar headache, a fever to 104 degrees F or higher with shaking chills, general malaise, myalgia, chest pain, and sometimes pneumonia and hepatitis. Cattle, sheep, goats, and ticks are the primary reservoirs of the etiologic agent, Coxiella burnetii. Humans are usually infected by inhaling infectious aerosols. Because C. burnetii can survive for long periods in the environment, it poses a continuing health hazard once it is disseminated. Q fever usually occurs sporadically, but large outbreaks are frequently observed throughout the world, particularly among abattoir workers and personnel working in research centers. Q fever endocarditis follows a chronic course and is frequently fatal. Tests for antibodies to C. burnetii are required for confirmation of the diagnosis. Tetracyclines remain the mainstay of treatment for acute Q fever, and tetracyclines in combination with other antibiotics have been advocated for patients with Q fever endocarditis. Vaccines for Q fever have been proven effective in clinical trials.

A patient is described who developed unilateral seizures whilst being treated with recombinant interferon for hairy cell leukemia. Special features included the relatively low dose of interferon, the focal aspect of the epilepsy and the high resistance to anticonvulsants. Oligoclonal banding of cerebrospinal fluid proteins may have resulted from polyclonal activation of bone marrow plasma cells during interferon treatment. Disturbances of consciousness, dysphasia, visual hallucinations, upper motor neuron deficit, tremor, dizziness, numbness, myalgia and headache, all of them neurological complications of interferon treatment, are discussed.

This study was designed to evaluate the clinical tolerance to multiple IM injections of rDNA-produced human alpha-2 interferon (IFN) (Schering-Plough 30500) in patients with solid tumours. IFN was administered in escalating IM doses in separate groups of patients daily for 14 days and then twice weekly for a further 10 weeks. The dosage levels were 1, 3, 10, and 30 million U/injection. Subjective toxicity could be divided into two types, acute and chronic. The acute reactions took the form of an influenza-like syndrome consisting in chills, rigors, headache, tremor, nausea, vomiting, and myalgia. These symptoms were dose-related but tachyphylaxis developed with continued dosing. The chronic toxicity consisted of malaise, lethargy, fatigue, anorexia, and confusion. These symptoms were not so dose-dependent and tended to become more severe with prolonged treatment. Objective toxicity consisted of myelosuppression and liver dysfunction. Granulocyte counts below 1.0 X 10(9)/l were seen in three patients at the 30-million-U level, with platelet counts less than 100 X 10(9)/l in two of these. Elevation of the liver enzymes were seen in all five patients treated at 30 million U, but returned to normal after 1 week without IFN in all but one patient. A tolerable dose (IM) for phase II/III studies lies between 3 and 10 million U for daily scheduling and between 10 and 30 million U for twice-weekly injections.

Fourteen patients with metastatic renal cell carcinoma received methyl-G weekly at a starting dose of 600 mg/m2 (five patients) and 500 mg/m2 (nine patients) intravenously. All 14 patients are evaluable for response and toxicity. No antitumor responses were observed. Six patients achieved stabilization of disease for 8 to 42 weeks. Toxicity was nonhematologic and included nausea or vomiting (35%), fever with shaking chills (28%), diarrhea (21%), myalgia (63%), paresthesia (49%), and bilateral foot drop (7%). Methyl-G does not appear to have activity against renal cell carcinoma.

This study examined the effects of exercise-induced muscle damage on tremor and proprioception components of neuromuscular function. Six male and six female volunteers (aged 18-30 yr) performed 50 maximal eccentric muscle actions using the forearm flexors of the nondominant arm. Forearm flexor tremor and perception of voluntary force and joint position were monitored to assess changes in neuromuscular function. Data were analyzed using REANOVA. Serum creatine kinase activity increased from a baseline value of 68 +/- 13 IU.l-1 to 2849 +/- 852 IU.l-1 5 d after exercise (P < 0.05). This was accompanied by prolonged impaired joint range of motion (P < 0.01) and reduced maximum strength (P < 0.01). Muscle soreness peaked 3 d postexercise (P < 0.01; Wilcoxon test). Tremor amplitude was increased (P < 0.01) until 48 h after exercise, whereas the power frequency spectrum was unaffected. Perception of joint position at elbow angles of 1.57 rad (P < 0.01) and 2.09 rad (P < 0.05) and perception of force (P < 0.01) were significantly impaired when the control arm acted as the reference. Joint positions were more accurately reproduced when the experimental arm acted as its own reference. The increase in tremor amplitude and loss of proprioceptive function in the days after damage-inducing eccentric exercise suggest significant impairment of neuromuscular function.

Motor disorders affecting the orofacial musculature include bruxism, chronic orofacial muscle pain affecting the jaw and neck muscles and the involuntary waking period disorders such as orofacial dyskinesia, oral mandibular dystonia, tremor and others. Research at UCLA has touched these and many other areas. Current results have indicated the usefulness of contingent afferent electrical stimulation of the lip to control bruxism; provided information regarding the fatigue, endurance and recovery faculties of the protrusive jaw muscles; explored the issue of chronic muscle hyperactivity inducing headache pain; and worked with botulin toxin as a method to treat orofacial dystonia and dyskinesia.

Whereas early formulations of addictive behaviour placed great emphasis upon withdrawal as a defining feature, current views focus more upon compulsive use as its central characteristic. However, the withdrawal syndrome continues to occupy an important place in the study of the addictions. It is interesting both in its own right and in relation to the development and maintenance of the compulsive use of drugs. Despite the attention devoted to withdrawal phenomena over many years, precise demarcation of the withdrawal symptoms associated with drugs of dependence has proved difficult to achieve. Withdrawal from all drugs of dependence appears to lead to mood disturbances although the extent to which these are due to the pharmacological actions of the drugs or to other physiological or psychological processes is unclear. Sleep disturbance is also common, although again direct links with the pharmacological actions of the withdrawn drug are yet to be established. Withdrawal from alcohol, benzodiazepines and opiates is often associated with somatic symptoms. In the former two cases, these can involve sweating, tremor and occasionally seizures. Perceptual disturbances have also been reported. In the case of opiates, flu-like symptoms are often reported, including muscle aches and gastric disturbances. In the case of nicotine, heightened irritability has been established as a direct pharmacological withdrawal effect. Characterization of stimulant withdrawal is still uncertain. There is little evidence of somatic symptoms but depression may occur as a result of a physiological rebound. There is also uncertainty over what role pharmacological withdrawal symptoms play in maintaining compulsive use.(ABSTRACT TRUNCATED AT 250 WORDS)
