We present the case of a young man on maintenance hemodialysis who developed frequent episodes of 'fluttering, racing heartbeats', hot flashes, profuse sweating, anxiety, dizziness, and shortness of breath. These symptoms started approximately 1 month after taking cimetidine 400 mg/day with an occasional extra dose. His workup included a total of 72 h of cardiac monitoring, two-dimensional echocardiogram, and thyroid function tests, all of which were essentially unremarkable. When the drug cimetidine was temporarily discontinued, and on another occasion after the drug was totally withdrawn, the patient noticed marked improvement in his symptoms at 48 h with total resolution on the 5th day after discontinuation. This is the 2nd such case reported in the literature.

A 61-year-old woman presented to the emergency department after experiencing palpitations, shortness of breath, and syncope while taking a shower. Her husband revived her with mouth-to-mouth resuscitation. She had had a similar episode three days earlier while making her bed and had lost consciousness for about 10 sec. She did not appear to have had a seizure. Five months earlier, while taking a walk, she had experienced dizziness, dyspnea, and chest pressure lasting about an hour. A workup at that time included cardiac catheterization, lung scanning, and esophagogastroduodenoscopy, but no abnormality was found. Lower extremity edema was noted.

Data about tiredness and lack of energy from 91 bone marrow transplant (BMT) survivors and 73 patients receiving maintenance chemotherapy were collected. A correlational evaluation revealed that these two distressing symptoms were associated with physical, psychological, cognitive and social dimensions of quality of life (QOL). A stepwise regression model for BMT survivors showed that both tiredness and lack of energy could be predicted by the combined effect of difficulty concentrating and overall psycho-social adjustment. In addition, dizziness was also influencing tiredness. Lack of energy was predicted in the chemotherapy patients with the combined effects of adjustment to social environment, shortness of breath and psychological symptom distress (R2 = 0.80). In the same group of patients, tiredness was explained by a model consisting mainly of physical symptoms and cognitive symptoms, associated probably with the chemotherapy they were receiving, together with social adjustment (R2 = 0.86). The identification of the reasons behind tiredness and lack of energy in cancer patients, broadly defining fatigue and commonly experienced by them, will have implications for both patient education and the design of appropriate interventions to combat fatigue.

Disorders of the cardiovascular system are common. Heart pain is one of the most frequent complaints leading patients to seek medical help. Although psychologically conspicuous behaviour in patients with functional cardiac complaints are well known, they are--if at all--diagnosed quite late. Descriptive diagnostics of functional cardiac complaints according to the International Classification of Diseases (ICD-10, Chapter 5) are discussed (Figure 1). Possible physical causes of the disease must first be excluded. In a second step it must be clarified whether the complaints even those non-verbally conveyed are due to psychic illness in a narrower sense. Anxiety and depressive disorders must be taken into consideration here. If the patient demonstrates an avoidance behavior in the case of anxiety, than an agoraphobia can be assumed; in episodic paroxysmal fear on can assume panic attacks in which vegetative anxiety equivalents such as shortness of breath, numbness, palpitation of the heart, tachycardia and chest pain are prominent often accompanied by trembling, perspiration, nausea and dizziness. The different depressive disorders are characterized by a dejected mood, loss of interest, loss of enthusiasm and drive reduction; the disorders are divided up according intensity and course. Within the scope of depressive physical symptoms, frequently unpleasant sensations and pain in the chest area are described along with concern, despair, and an increase in self-observation. If no psychic disturbance in a narrower sense can be diagnosed, then the diagnosis of a somatoform disorder allows for this behavior. It is characteristic for this category of illness that the repeated presentation of physical symptoms in connection with the persistent demand for medical treatment may be observed although no physical causes can be demonstrated. The patients insist that their complaints are of a physical origin despite the doctor's assertion that this is not the case. If the symptoms are related to vegetative innervated organs then one speaks of somatoform autonomous functional disorders (F45.3, Table 1). Cardiovascular disorders fall within this scope. Further diagnoses within the spectrum of somatoform disorders are hypochondric and somatization disorders which demonstrate a variety of symptoms and inconsistent and frequently changing complaints. If a descriptive diagnosis can correspondingly be made then further analysis of the disorder must be carried out in order to reach an indication for psychotherapeutic treatment. From a psychodynamic point of view, the personality- and conflict-related background of the disturbance is relevant. Quite often unconscious ambivalent separation conflicted--be they real are fantasized situations of being left or being left alone--may be observed to trigger cardiovascular symptoms. In the cognitive-behavioral therapeutic tradition an exact analysis of the patients symptomatology is carried out in which prior and actual cause factors of the symptoms are looked for. Irrespective of the different approaches, information on the context of the complaints both on a biological, intrapsychic and interpersonal level is necessary for psychosomatic diagnostics. The better the causal conditions are known on the basis of which functional cardiovascular complaints have arisen, the easier it is to recognize those factors that will influence a change and allow a therapeutic approach. This is best done in cooperation with practitioners and internists who still have a key position in the diagnosis and treatment of patients with functional cardiac disorders. The ways and means in which they conduct the anamnesis is decisive in leading their patients to regard psychosomatic diagnostics as being either stuck in the so-called "psycho corner" or as a helpful relationship which they can accept.

We report the case of a patient with the acquired immunodeficiency syndrome (AIDS) whose death occurred within 30 hours of hospitalization due to disseminated cryptococcosis, manifested by dizziness, cough, and shortness of breath. The clinical picture was consistent with pneumocystis pneumonia, and antibiotic therapy with corticosteroids was initiated. Despite initial improvement, the patient's condition quickly worsened, resulting in cardiorespiratory arrest and death. Autopsy revealed cryptococci in several organs. Sudden, rapid deterioration and death are rare consequences of disseminated cryptococcosis, and steroids may worsen the course of the disease. On the basis of this case and review of similar cases in the literature, we recommend early consideration of disseminated cryptococcosis in AIDS patients with pneumonia. Early diagnosis and appropriate therapy are essential to reduce morbidity and mortality.

This report concerns a 74-year-old patient who had undergone aortic valve replacement 11 years earlier. On admission, the patient complained of shortness of breath when climbing two flights of stairs; there was no history of dizziness, fainting or sensations of arrhythmias. An ECG at rest showed first-degree atrioventricular (A-V) block together with left bundle branch block (LBBB). On bicycle ergometry, there was a fall in blood pressure and in heart rate due to a second-degree (2:1) A-V block along with the LBBB. After termination of exercise, the PR interval increased further from 0.24 s to >0.3 s, together with right bundle branch block (RBBB) and 1:1 A-V conduction instead of LBBB. Finally, at a constant atrial rate of 98/min, the RBBB disappeared, LBBB recurred, again with 2:1 A-V conduction. The diagnosis was bilateral BBB together with first degree A-V block at rest and higher-degree A-V block on effort. The patient underwent pacemaker implantation and was discharged shortly thereafter free of symptoms.

Identification of patients with acute cardiac ischemia (ACI) remains challenging. The object of this study was to examine the role of clinical findings in the diagnosis/triage of emergency department (ED) patients with symptoms suggestive of ACI. The study was designed as a secondary data analysis of a multicenter prospective controlled clinical trial. It was set in 10 midwest, southeast, and northeast U.S. hospitals, and 10,689 patients with chest pain or other symptoms suggesting ACI presenting from May 1993 to December 1993, participated. The results indicated that ACI patients were more likely to have chest pain as a chief complaint or presenting symptom (P = 0.001). The presenting symptom of nausea was more commonly associated with a final diagnosis of ACI (P = 0.003). Shortness of breath as the chief complaint and presenting symptoms of abdominal pain, nausea, dizziness, and fainting were less frequent among patients with a final diagnosis of ACI (P = 0.001). A past history of diabetes mellitus, myocardial infarction, or angina pectoris was more frequently associated with a final diagnosis of ACI (P = 0.001). A lower pulse rate in patients with a final diagnosis of ACI (P = 0.001) was not considered clinically significant. Median first and highest systolic blood pressures (SBPs) were higher, median lowest SBPs were lower, median diastolic blood pressure of the lowest SBPs were lower, and initial and highest pulse pressures were wider in patients with a final diagnosis of ACl (P = 0.001). On arrival, these blood pressure variables in AMI patients, subsequently classified as Killip class 4, were above the threshold for this classification. Rales were more commonly present in patients with a final diagnosis of ACI (P = 0.001). All primary ST-segment abnormalities, Q waves, and T-wave abnormalities, except T-wave flattening, were seen more frequently in patients with a final diagnosis ACI (P = 0.001). Normal ECGs were more frequently associated with a non-ACI final diagnosis, yet 20% of AMI patients and 37% of Unstable Angina Pectoris (UAP) patients had normal ECGs. It can be concluded that certain clinical features can help to identify ED patients with ACI. Initially normal ECGs can be seen in 20% of patients with AMI and 37% of patients with UAP. Patients with ACI can present with "normal" blood pressures and develop cardiogenic shock. Clinical outcome data for ACI patients are presented.

On rare occasions benzocaine has produced methemoglobinemia from oral, rectal and dermal exposures. There is disagreement whether this is an idiosyncratic event or a dose-related event. To gain a better perspective on this problem we retrospectively reviewed cases at 4 large regional poison centers of children <18-y of age from 1993-1996. One hundred and eighty-eight benzocaine exposures were reported. Mean and median ingested dosage were 86.8 (+/- 89.5) mg/kg and 50 mg/kg, respectively. Fifty-eight patients (30%) were managed in the emergency department; 8 patients had methemoglobin levels determined. One child had a methemoglobin level of 19%; all others were <1%. One hundred and seventy-three patients (92%) remained asymptomatic. Other symptoms were minor: oral numbness (8), vomiting (3), and 1 each of oral irritation, dizziness and nausea. In this series of accidental ingestions of benzocaine-containing products cyanosis was rare and apparently not dose related. These cases may be safely managed at home with telephone follow up for at least 2 h. If there is evidence of cyanosis, dusky pallor, shortness of breath, or change in mental status direct medical evaluation should be recommended.

We used structural equation modeling (SEM) to test the hypothesis that childhood instrumental and vicarious learning experiences influence frequency of panic attacks in young adulthood both directly, and indirectly through their effects on anxiety sensitivity (AS). A total of 478 university students participated in a retrospective assessment of their childhood learning experiences for arousal-reactive sensations (e.g., nausea, racing heart, shortness of breath, dizziness) and arousal-non-reactive sensations (i.e., colds, aches and pains, and rashes). SEM revealed that learning history for arousal-reactive somatic symptoms directly influenced both AS levels and panic frequency; AS directly influenced panic frequency; and learning history for arousal-non-reactive symptoms directly influenced AS but did not directly influence panic frequency. These results are consistent with the findings of previous retrospective studies on the learning history origins of AS and panic attacks, and provide the first empirical evidence of a partial mediation effect of AS in explaining the relation between childhood learning experiences and panic attacks in young adulthood. Implications for understanding the etiology of panic disorder are discussed.

Combination drug therapy and enhanced patient management techniques result in increased survival for many AIDS patients. This phenomenon has brought the issue of fatigue, a common and difficult side effect of HIV/AIDS treatment, to the forefront. Three-quarters of the AIDS patients surveyed in a recent study indicated that fatigue negatively affects their quality of life and influences their willingness to continue aggressive treatment. New advances for combating fatigue include the use of nutritional therapy, anti-depressants, anti-infectives, medications that boost the production of red blood cells, hormone replacement, exercise, massage, and acupuncture. The most common source of fatigue in HIV-positive patients is anemia, which also causes shortness of breath and dizziness. Anti-HIV medications may inhibit red blood cell production. An alternative treatment, Epoetin alfa, works by increasing low levels of naturally producing erythropoietin, a protein manufactured in the kidneys. Fatigue resulting from low testosterone levels can be treated with anabolic steroids. Poorly functioning adrenal glands can be the cause of fatigue in patients with advanced disease. Taking hydrocortisone pills is often effective. Depression is the fourth most common cause of fatigue. Antidepressants work well without traditional side effects.
