Electroconvulsive therapy is extremely effective and is the fastest acting antidepressant treatment now available, although not necessarily limited to use with depression. Despite years of experience with this technique and its unparalleled successes, patients continue to be affected by mostly transient, but sometimes impairing side effects from memory problems and cardiovascular changes associated with ECT treatments. Nausea, headache, muscle aches, and other side effects that have been referenced in the literature and clinical experience will also be discussed in this review. Helpful literature with recommendations on minimizing the risks of these side effects and improving the tolerability of the electroconvulsive treatments will also be presented.

The efficacy and safety of recombinant human interferon gamma (rIFN-gamma) in the reduction of opportunistic disease in patients with advanced HIV-1 infection are assessed. A 12-month double-blind, placebo-controlled, multicenter, Phase III trial of rIFN-gamma in HIV-positive patients with CD4 < 100 x 10(9)/liter on stable antiretroviral therapy. Eighty-four patients were allocated treatment on a 1:1 basis to rIFN-gamma or placebo. Patients received rIFN-gamma 0.05 mg/m(2) or 0.9% saline subcutaneously three times weekly for 48 weeks (optional extension to 18 months). The primary end point was the incidence of opportunist infections (CDC categories B/C). Secondary end points included mortality, immunological, and virological parameters. Patients on placebo had a mean of 3.45 opportunist infections (OIs) in the first 48 weeks. Patients treated with rIFN-gamma had a mean of 1.71 OIs (p = 0.04). However, the model showed overdispersion and the inclusion of a dispersion factor raised the p value to 0.13. rIFN-gamma appeared to have a particular effect on the incidence of Candida, herpes simplex, and cytomegalovirus infections. Three-year survival in the rIFN-gamma arm was 28% compared to 18% in the placebo group (not significant). rIFN-gamma-associated side-effects of headache, fatigue, rigors, influenza-like symptoms, depression, myalgia, and granulocytopenia were reversible. There was no evidence for HIV activation. Although not significant, the trend towards decreased opportunistic infections and increased survival warrants consideration of further trials of rIFN-gamma. The study gives additional information on the safety profile of this cytokine.

This investigation compared differences in the occurrence of symptoms in participants with CFS, melancholic depression, and no fatigue (controls). The following Fukuda et al. [Ann. Intern. Med. 121 (1994) 953] criteria symptoms differentiated the CFS group from controls, but did not differentiate the melancholic depression group from controls: headaches, lymph node pain, sore throat, joint pain, and muscle pain. In addition, participants with CFS uniquely differed from controls in the occurrence of muscle weakness at multiple sites as well as in the occurrence of various cardiopulmonary, neurological, and other symptoms not currently included in the current case definition. Implications of these findings are discussed.

Sixteen patients with polycythaemia vera or essential thrombocythaemia were treated with interferon-alpha in order to normalize elevated platelets. Patients were followed for 6 months and the frequency and intensity of symptoms and side effects were recorded before and during the study period by the patients and by the doctor. Health-related quality of life was also assessed. The most frequently reported pretreatment symptoms were fatigue, headache and muscle pain. The intensity of fatigue initially increased during treatment and there was no relief of any of the three most frequent symptoms during the treatment period. Common interferon-related symptoms such as fever and chills were most frequently reported after one week. After one month of treatment, symptoms related to the gastrointestinal tract reached a peak. Two patients discontinued treatment during the study period. Another patient suffered severe depression after the study period when still on interferon. There was no difference between the frequency of symptoms recorded by the doctor and that reported by the patients.

Saint John's wort (Hypericum perforatum L.) is a herbal remedy that is effective in the treatment of mild to moderate depression. In traditional folk medicine, oily extracts of St. John's wort are used for topical treatment of wounds, burns and myalgia. The lipophilic phloroglucin-derivative hyperforin has antibacterial and antiinflammatory effects. These effects could be of relevance in topical treatment of infected wounds and other dermatoses, but no studies have been conducted so far. The naphtodianthrone hypericin is a photodtodynamic active substance that kills tumor cells via the induction of apoptosis. Hypericin also displays antiviral activity in vitro. In vivo, intravenous or oral treatment with hypericin of HIV-infected subjects did not result in a reduction of the virus load. Most of the patients treated with hypericin experienced phototoxicity. Similar phototoxic symptoms ("hypericism") have been observed in grazing animals ingesting large amounts of St. John's wort. In contrast, antidepressant medication with St. John's wort usually does not produce phototoxic symptoms. Recent pharmacokinetic studies suggest that the phototoxic threshold level of hypericin is not reached with dosages used for the oral treatment of depression. However, very recent reports demonstrated interactions of St. John's wort with other drugs such as digoxin, indinavir and cyclosporin. Blood levels of these drugs were dramatically decreased by St. John's wort. This should be considered in the treatment of skin conditions with antiviral drugs or cyclosporin.

In numerous studies of symptoms in patients with chronic hepatitis C there has been no systematic assessment of both fatigue and extrahepatic manifestations. Our objective was to assess the prevalence of fatigue in patients with hepatitis C virus (HCV) infection, and to identify associations between fatigue and clinical and biological hepatic and extrahepatic manifestations. We studied 1614 patients. Data were prospectively recorded during the first visit of patients infected with HCV and the prevalence of fatigue and its association with dermatological, rheumatological, neurological and nephrological manifestations; diabetes; arterial hypertension; auto-antibodies, and cryoglobulinaemia were assessed. Then, using multivariate analysis, we identified demographic, biochemical, immunological, virological, and histological factors associated with the presence of fatigue. Fatigue was present in 53% of patients (95% confidence interval 51-56). In 17% of patients (95% confidence interval 15-19) fatigue was severe, impairing activity. Five other extrahepatic manifestations had a prevalence above 10% including, in decreasing order: arthralgia, paresthesia, myalgia, pruritus, and sicca syndrome. In univariate and multivariate analyses, fatigue, in comparison with the absence of fatigue, was associated with female gender, age over 50 years, cirrhosis, depression and purpura. Independent of these associations, fatigue was associated with arthralgia, myalgia, paresthesia, sicca syndrome and pruritus. The prevalence of fibromyalgia (as defined by the association of fatigue with arthralgia or myalgia) was 19% (95% confidence interval 17-21). There was no significant association between fatigue and the following characteristics: viral load or genotype, alcohol consumption, abnormal thyroid function, and type and level of cryoglobulinaemia. Hence, fatigue is the most frequent extrahepatic manifestation in patients infected with HCV. Fatigue is independently associated with female gender, age over 50 years, cirrhosis, depression and purpura.

Earlier investigations have shown that stimulation of peripheral afferent nerves induces prolonged changes in the excitability of the human motor cortex. The present study compared the effect of experimental pain and non-painful conditioning stimulation on motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) in the relaxed first dorsal interosseous (FDI) and flexor carpi ulnaris (FCU) muscles. The MEPs were measured in 10 healthy subjects, and stimulus-response curves were generated before and after each of four stimulation paradigms conducted in random order on separate occasions: (a) control; (b) "dual stimulation" consisting of electrical stimulation of the FDI motor point paired with TMS; (c) painful infusion of hypertonic saline in the FDI muscle; and (d) pain combined with dual stimulation. There were no significant changes in FDI MEPs following the control paradigm, and dual stimulation induced an increase in the FDI MEPs only inconsistently. In contrast, the painful stimulation and the combined pain and dual stimulation paradigms were followed by significant suppression of the FDI MEPs at higher stimulus intensities. No changes were observed in the FCU MEPs following the four paradigms. In two additional subjects, the responses evoked in FDI by direct stimulation of the descending corticospinal tracts were significantly depressed following painful stimulation of the FDI, although the ulnar-evoked M-waves remained constant. It is concluded that muscle pain is followed by a period with profound depression of MEPs amplitudes in the resting muscle, but that these changes are at least in part due to a lasting depression of the excitability of the motoneurones in the spinal cord. Hence, painful stimulation differs from non-painful, repetitive stimulation, which facilitates the corticomotor pathway.

This study explores thermal sensitivity and thermal nociception for signs of central sensitization in the area of referred muscle pain. Two groups of 24 healthy subjects (ss) each, and with mean ages of, respectively, 27 and 55 years, were first trained in quantitative sensory testing and pain rating. Then, in a second session, referred pain was evoked by injection of 6% hypertonic saline into the infraspinatus muscle. Cold and warm thresholds, synthetic heat threshold (SHT--evoked by an alternating pattern of adjacent cold and warmth), and thermal pain thresholds were measured within the referred pain area at a rate of 1/20 min for 60-120 min. All ss of both groups experienced referred pain mostly in the upper arm and of medium intensity. Pain lasted for approximately 12min with a shorter duration in the older group (p<0.02). The cold threshold increased significantly (p<0.001), and the warm threshold slightly, after the injection and remained high for the whole observation period (i.e. lower and higher temperatures were necessary to elicit cold and warmth, respectively). Threshold recovery was more delayed in the older age group. Of those 28 ss in whom cold pain threshold could be followed during the whole observation period, 18 ss showed an immediate threshold decrease of average 6 degrees C which outlasted the observation period. Four ss responded with a threshold increase. Heat pain thresholds were not affected in the referred pain area. Average synthetic heat threshold did not change; there were, however, distinct and lasting individual threshold shifts in either direction. Ss with lowered cold pain thresholds or evident threshold shifts for synthetic heat had also higher pain ratings. The results demonstrate that experimental muscle pain can induce long-lasting changes in thermal sensitivity and nociception. The unexpected cold threshold increase may tentatively be explained as an expression of long-term depression. The decrease of cold pain threshold or SHT in subgroups of ss may indicate central sensitization. However, the observed changes in this experiment do not provide an unambiguous indicator for central sensitization which seems to be rather individual and might depend on pain intensity and proneness to express central mechanisms of sensitization. Therefore in clinical pain states the individual pattern of sensory abnormalities has to be analysed and interpreted in addition to the pain parameters to assess central involvement.

A 50-year-old African American woman presented with bilateral lower extremity pain, a history of falls during the past several months, and personality and behavior changes. She had been in good health until approximately 5 months before admission, when she began to fall with increasing frequency, often while going down a flight of stairs. She described these falls as her "legs giving out" and feeling very heavy and unsteady. There was no head trauma or loss of consciousness. Her daughter noticed that her gait had become somewhat unsteady during the last several months. Her family also noted a change in her personality at this time. Previously, she had been a very tidy person who took great care with her appearance, who was working as a customer service representative. However, she had become less social and very withdrawn. She had been observed putting on dirty clothes after showering, as well as eating constantly. The patient denied any fevers, chills, night sweats, headaches, vision changes, or tinnitus. She also denied any rashes, muscle pain, or intolerance to heat or cold. There was no history of seizure disorder or depression. Her past medical history was notable only for hypertension and being a passenger in a motor vehicle crash 1 year before admission. She denied any alcohol, tobacco, or illicit drug use, and had no travel history other than coming to the United States, as she was originally from Trinidad. On physical examination, she was a moderately obese African American woman with a flat affect, psychomotor slowing, and alopecia of the scalp. She was alert and oriented to person, place, and time, but had a score of 26 out of 30 on the Mini-Mental State Examination. She lost points only for recall; she had no difficulty with serial 7s. Her cranial nerves were intact and her speech was fluent, although sparse, and she did not make any paraphasic errors. Her muscle strength was 5/5 in both the upper and lower extremities. Reflexes were 2+ in the upper extremities and 1+ in the lower extremities, and toes were downgoing bilaterally. She had intact sensation to light touch and pinprick, but markedly diminished proprioception of her lower extremities bilaterally. She had a wide-based gait with a positive Romberg sign and was markedly ataxic. Rectal examination yielded a positive guaiac test with brown stool, normal tone, and no masses. The remainder of the physical examination was normal. Laboratory studies revealed pancytopenia with a hematocrit of 22.7% and a mean corpuscular volume of 118.2 fL. A peripheral smear that was performed on admission, prior to transfusion, revealed macrocytic red cells and hypersegmented neutrophils.

Symptoms serve as intervention foci for patients and health care providers. Research has established a relationship between symptoms and quality of life for persons living with HIV/AIDS. This article reports symptom prevalence and intensity data that include gynecological and cognitive symptoms self-reported by HIV-infected women (N = 118). Using a cross-sectional, descriptive design, data were obtained using the Center for Epidemiological Studies-Depression Scale (CES-D), Medical Outcomes Study Short Form-36 (MOS SF-36), and the revised Sign and Symptom Check-List for Persons Living with HIV/AIDS (SSC-HIV). Prevalent symptoms were depression (83%), muscle aches (84%), weakness (80%), and painful joints (71%). Symptoms with the highest mean intensity, however, were headaches, rash, insomnia, vaginal itching, and shortness of breath at rest. Symptoms also significantly predicted role functioning. This study contributes to our understanding the nature of symptoms and the influence of symptoms on role and physical functioning among HIV-infected women.
