Side effects play a significant role in the selection of drugs to be used in panic disorder/agoraphobia whose polyphobic symptomatology often includes a suspiciousness about taking drugs and a fear of undesired side effects which may lead to the refusal of treatment. The safety, side effects and patients' acceptance of alprazolam and imipramine versus placebo were evaluated in 1168 subjects with panic disorder/agoraphobia who had been enrolled in the second phase of the Upjohn World Wide Panic Study. Side effects that worsened over baseline to a greater extent with alprazolam than with imipramine and placebo were sedation, fatigue/weakness, memory problems, ataxia and slurred speech. In the imipramine group blurred vision, tachycardia/palpitations, insomnia, sleep disturbance, excitement/nervousness, malaise, dizziness/faintness, headache, nausea/vomiting and decrease in appetite were worse than in the other groups. In the placebo group the anxious symptoms were most prominent. The highest level of compliance was shown in the alprazolam-treated group and the lowest in the placebo-treated group. Strong predictors of side effects were not observed. If a side effect profile is known, it will be easier for a clinician to choose the right drug and the appropriate management by taking into account compliance, safety and efficacy in each patient under treatment. Further information about side effects in long-term maintenance treatment would be of great clinical pertinence in ensuring safety and enhancing patients' quality of life.

We report a rare case of Hodgkin's disease in which intracranial involvement developed during the course of the patients illness. A 20-year-old man who had complained of lymph node swelling on the right neck was admitted to a hospital in December 1978. Lymph node biopsy revealed Hodgkin's disease, and he was treated by various series of chemotherapy and radiotherapy with unsatisfactory results. He was transferred to Yamanashi Medical College Hospital in June 1985. He was in a far-advanced state at the time, and palliative treatment was applied. In the middle of May 1986, he complained of headache, tinnitus, and sleeplessness. Vomiting and tremor were observed by the end of May 1986. Brain CT scan revealed a space occupying lesion in the right temporal region. Whole brain irradiation of 45 Gy was effective, and the lesion disappeared. However, his general condition deteriorated and he died in November 1986. Brain autopsy could not be performed.

The efficacy of tropisetron, a new 5-HT3 receptor antagonist, was evaluated in a group of 15 children with a variety of malignant tumours. The majority of children (14/15) received fractionated chemotherapy and on day one complete control of acute nausea and vomiting was observed in 68.7% of all patients with a single, 15-minute, i.v. infusion of tropisetron. Partial control of vomiting was observed in 25% of patients and of nausea in 31.3% of patients on Day 1. Complete control of delayed nausea and vomiting was more variable, with an observed range between 50%-81% of patients over Days 2-6. There was no loss of appetite in 75% of patients treated with tropisetron on Day 1 and, more variably, in 62%-87% of patients on Days 2-6. Side effects were recorded in 18.8% of chemotherapy cycles, the most significant being insomnia in 12.5% of cycles and slight fever in 6.3% of cycles. It was concluded that tropisetron was well suited for children and could be recommended for those receiving a high burden of fractionated chemotherapy.

Headache, nausea, vomiting, insomnia and peripheral edema are the most important symptoms of acute mountain sickness (AMS), which occur within 6 to 12 h. after exposure to altitudes of more than 2500 m a. s. l. Usually, these symptoms resolve spontaneously; however, they may progress to life-threatening cerebral edema in some cases. High-altitude pulmonary edema (HAPE) is a noncardiogenic edema, which is often preceded by acute mountain sickness. Frequency and severity of these illnesses depend on the altitude, the rate of ascent and the degree of individual susceptibility. A low hypoxic ventilatory drive, sodium and water retention as well as increased capillary permeability are the most important pathophysiological factors which contribute to hypoxemia and edema formation in AMS. They are also important in the pathophysiology of HAPE. In addition, excessive hypoxic pulmonary artery hypertension is most likely crucial in the pathogenesis of HAPE. Constitutional factors which regulate ventilation and pulmonary artery pressure under hypoxia are considered the most important determinants of susceptibility to AMS and HAPE.

The objective of this open-label, randomized, multicenter study was to compare the efficacy and safety of fleroxacin, 400 mg administered orally once daily, and amoxicillin/clavulanate potassium (AMX/CP), 500 mg/125 mg administered orally three times daily, for 4-21 days to patients with skin and soft tissue infections (SSTIs). The specific diagnoses in both groups were primarily skin abscess, impetigo, and skin ulcer, as well as wound infection erysipelas, folliculitis, cellulitis, and lymphangitis. A total of 285 patients were randomized to treatment in a 2:1 ratio, 190 in the fleroxacin group and 95 in the AMX/CP group. Adult male or female inpatients or outpatients were included in the trial and were followed up after 3-5 days of therapy and 3-9 days after completion of therapy for assessment of bacteriologic, clinical, and safety parameters. The most frequently isolated pathogen in both treatment groups was Staphylococcus aureus. Bacteriologic cures were observed in 87 (76%) of 115 evaluable patients in the fleroxacin group and in 41 (72%) of 57 evaluable patients in the AMX/CP group. Clinical cure was seen in 86 (75%) of 114 patients in the fleroxacin group and 45 (79%) of 57 patients in the AMX/CP group. Clinical adverse events related to the trial medication were reported by 40 (21%) of 189 patients in the fleroxacin group and by 16 (17%) of 95 patients in the AMX/CP group. In both groups, most adverse events were mild or moderate in severity and involved the digestive system (primarily diarrhea, nausea, and vomiting). In the fleroxacin group, adverse events affecting the central nervous system (mainly dizziness, insomnia, somnolence) also were reported. In this study, both fleroxacin and amoxicillin/clavulanate potassium were effective and well tolerated in the treatment of skin and soft tissue infections.

Acute mountain sickness (AMS) affects, to varying degrees, all travelers to high altitudes (elevations greater than 5280 feet). In a small percentage of patients, AMS can lead to high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE). Symptoms of AMS range from a combination of headache, insomnia, anorexia, nausea, and dizziness, to more serious manifestations, such as vomiting, dyspnea, muscle weakness, oliguria, peripheral edema, and retinal hemorrhage. Although the primary cause of these symptoms is related to the reduced oxygen content and humidity of the ambient air at high altitudes, the physiologic pathway relating hypoxemia to AMS and its sequelae remains unclear. Tips on self-diagnosis and symptom recognition are critical elements to be included in educating patients who are contemplating a trip to high altitudes. Preventive strategies include allowing 2 days of acclimatization before engaging in strenuous exercise at high altitudes, avoiding alcohol, and increasing fluid intake. Conditioning exercise for patients older than 35 years is also recommended before departure. A high-carbohydrate, low-fat, low-salt diet can also aid in preventing the onset of AMS. Acetazolamide (125 mg two or three times daily, or once at bedtime) has also been shown to reduce susceptibility to AMS and the incidence of HAPE and HACE. Although effective in treating cerebral symptoms of AMS, dexamethasone is not routinely recommended as a prophylactic agent for AMS.

Health-related quality of life (HQL) was assessed before and after either moderately or highly emetogenic chemotherapy. When the pretreatment HQL in patients who did not vomit after chemotherapy (n = 203) was compared to those who vomited (n = 230), it was found that patients who did not vomit had better physical, role, and social function scores as well as a better global quality of life score than did patients who had one or more episodes of vomiting. Furthermore, in patients who did not vomit, the pretreatment fatigue and anorexia scores were better than in patients who did vomit. Thus, pretreatment HQL scores appear to have value in predicting which patients will experience chemotherapy-induced emesis. In the week following chemotherapy, HQL change scores from prechemotherapy values for cognitive function, global quality of life, fatigue, anorexia, insomnia and dyspnea were significantly worse in the group experiencing emesis than in the group who remained completely free of emesis. There were no differences in physical, role, emotional and social function attributable to chemotherapy-induced vomiting.

When treating patients with psychoses, clinicians must often consider changing their treatment from one antipsychotic agent to another. The transition may be necessary because the patient experiences serious side effects or because the existing therapy no longer controls the patient's symptoms. A principal problem in changing antipsychotic agents is the potential for withdrawal symptoms resulting from discontinuation of the existing therapy. These syndromes can manifest as reemergence or worsening of psychosis, rebound or unmasked dyskinesia, and cholinergic-rebound symptoms. Withdrawal signs and symptoms may include insomnia, nausea, vomiting, anxiety, and agitation. When switching a patient to the new antipsychotic agent risperidone, the clinician can keep withdrawal symptoms to a minimum by considering the patient's clinical history and current status. For some patients, abrupt withdrawal of the current antipsychotic may be possible. For others, the dose of the previous medication must be gradually reduced before risperidone is initiated. In many cases, the transition is best made by overlapping the existing therapy and risperidone.

The clinical trial development programme of mirtazapine (Org 3770), performed in Europe and the United States, demonstrated an outstanding safety profile of this compound. The evaluation of the safety was based on data from all patients who took at least one dose of study medication during studies comparing mirtazapine with placebo, amitriptyline or other active comparators. A general indication of mirtazapine's safety is the significantly lower percentage of patients (65%) who complained of any adverse clinical experiences compared with the placebo- (76%) or amitriptyline-treated group (87%). Moreover, drop-out rates due to adverse clinical experiences were significantly lower than in the amitriptyline-treatment group. Mirtazapine has virtually no anticholinergic, adrenergic or typical selective serotonin reuptake inhibitor (SSRI) side effects. The only significantly higher incidences versus placebo were seen in the adverse clinical effects of drowsiness (23% versus 14%), excessive sedation (19% versus 5%), dry mouth (25% versus 16%), increased appetite (11% versus 2%) and weight increase (10% versus 1%). These complaints were typically mild and transient in nature, and decreased over time despite increased doses of mirtazapine. In contrast, significantly higher incidences of headache (5% versus 10%) and weight decrease (2% versus 6%), symptoms commonly seen in depressed patients, were recorded in the placebo-treated patients. Also, typical SSRI adverse events, such as nausea, vomiting, diarrhoea and insomnia, and symptoms of sexual dysfunction were registered less frequently in mirtazapine-treated patients than in the placebo-treated patients. Approximately 10% of the mirtazapine-treated patients in the clinical trial programme were older than 65 years. The pattern of adverse clinical experiences seen in this group of patients is fully in line with that seen in the overall patient population. The analysis of vital sign indices, i.e. blood pressure and heart rate, showed that no changes occurred with mirtazapine treatment; this pattern was fully comparable to that seen with placebo. Furthermore, very low incidences of clinically relevant changes in laboratory indices, such as the liver enzymes alanine aminotransferase and aspartate aminotransferase or neutropenia, were recorded in each treatment group. Mirtazapine has a very low seizure-inducing potential: only one case was recorded in a patient with a history of seizures during previous treatment with clomipramine. The low seizure-inducing potential combined with a lack of cardiotoxic properties allows safety in an overdose of mirtazapine, even in elderly patients. The only symptom seen in the patients taking an overdose of mirtazapine alone or in combination with other drugs was excessive but transient somnolence, which resolved spontaneously within a few hours. In conclusion, the new antidepressant mirtazapine offers clinicians a unique combination of strong efficacy and good safety.

We present the case of a 71-year-old female suffering from bipolar affective disorder type 2 and an old lacunar brain infarct who, under the combined treatment of fluoxetine for depression and low dose trazodone for the accompanying insomnia, developed a toxic delirium. The subject presented with mental state changes (confusion and agitation), hyperreflexia, diaphoresis, nausea, vomiting, fever, and a general tonic-clonic seizure which developed soon after an increase in the trazodone dose. One year prior to the above episode, she was hospitalized for a transient episode of agitated confusion while being treated with fluvoxamine for depression, alprazolam and brotazolam for the accompanying anxiety and insomnia. Both episodes subsided spontaneously when treatment was discontinued. This case reports the possible existence of increased vulnerability to hyperserotonergic states in elderly patients suffering from concomitant psychiatric and neurological disorders.
