Many primary care physicians wish to address the psychiatric aspects of their medically ill patients but are impatient with the abstract terminology used in psychiatry's past psychoanalytical period. Modern psychiatry is a more integrated field and considers the biological and social as well as the analytical contributors to disease. Using these newer concepts, we present a teaching model in which schizophrenia is viewed as a syndrome and is compared with the well-known medical syndrome of congestive heart failure. This approach facilitates the conceptualization of a complex psychiatric illness and makes it more appealing to primary care physicians by demonstrating common gound between medicine and psychiatry.

A 63 year old female, who was admitted to a psychiatric hospital for schizophrenia, was referred to our emergency room because of sudden loss of consciousness and convulsions. On arrival, she was drowsy and hypoxemic. Her chest X-ray showed cardiomegaly with pulmonary edema. ECG showed marked ST depression in precordial leads and serum chemistry revealed marked elevation of CPK, GOT and LDH along with hyponatremia and hypochloremia. She was immediately admitted to CCU on suspicion of acute non-transmural myocardial infarction complicated with congestive heart failure. After fluid restriction and intravenous infusion of dopamine she passed large amount of urine, and her consciousness level, electrolyte imbalance and ECG change, improved gradually. Although serum CPK level increased as high as 32,307 IU/ml, there were no signs of left ventricular asynergy on UCG and CPK isozyme analysis performed later revealed more than 99% of serum cCPK was MM-type. We concluded that water intoxication was the cause of the ECG change and the elevated serum CPK, GOT and LDH levels. There are few reports on elevated CPK level in association with water intoxication, in which rhabdomyolysis is speculated as the cause of CPK elevation. But there is no report on ECG change complicated with water intoxication. In our case, electrolyte imbalance caused by water intoxication seemed to play a major role in ST depression and QT prolongation. Although water intoxication is a rare disorder in the general population, it is not infrequent among patients with psychiatric diseases. Care must be taken when such patients present ECG change and serum enzyme elevation mimicking ischemic heart disease.

In the period from 1989 to 1998, 98 patients with suicidal tricyclic antidepressants poisoning were treated, including 47 men and 51 women from 16 to 74 (mean 35) years old. Thirty persons were poisoned by tricyclic antidepressants, in 68 remaining cases intoxications were mixed eg. including tricyclic antidepressants and benzodiazepines, phenothiazines, barbiturates, alcohol, amizepine, salicylates. The main causes of suicides were various kinds of depression (66%) as well as psychopathy and sociopathy (18%). Twenty patients attempted repeatedly to commit suicide. These were mainly patients suffering from endogenous depression, psychopathy and schizophrenia. In the examined group five patients died (5%) but three women out of them were aged, suffered from congestive heart failure and were poisoned with tricyclic antidepressants, benzodiazepines and barbiturates.

Angiotensin-II, a product of angiotensin converting enzyme (ACE) action, regulates vascular tone, stimulates the release of pro-inflammatory cytokines, activates NFkappaB, increases oxidant stress, and suppresses nitric oxide synthesis. Thus, angiotensin-II is pro-inflammatory in nature. Hence, increase in ACE activity and the concentrations of angiotensin-II initiate and perpetuate inflammation. Since ACE is present in many tissues including: the uterus, placenta, vascular tissue, heart, brain, adrenal cortex and kidney, leukocytes, alveolar macrophages, peripheral monocytes, neuronal cells and epididymal cells, this suggests that angiotensin-II may have a role in atherosclerosis, congestive cardiac failure, stroke, bipolar disorder, schizophrenia, dementia, Alzheimer's disease, psoriasis, atopic and non-atopic dermatitis, eczema, several acute and chronic inflammatory diseases, and cancer, conditions in which inflammation is known to play a significant role. This suggests that ACE inhibitors and/or angiotensin-II receptor blockers could be of significant benefit in the management of these conditions. Alternatively, structural analogues of presently available ACE inhibitors and angiotensin-II receptor blockers could be developed such that they are not only useful in the treatment of hypertension and CHF but also possess anti-inflammatory actions.

Angiotensin-II regulates vascular tone, stimulates the release of pro-inflammatory cytokines, activates NF-kappaB, increases oxidant stress, and suppresses nitric oxide synthesis, and thus, it functions as an inflammatory molecule. Since ACE is present in many tissues, this suggests that angiotensin-II may play a significant role in atherosclerosis, congestive cardiac failure, stroke, bipolar disorder, schizophrenia, dementia, Alzheimer's disease, psoriasis, atopic and non-atopic dermatitis, eczema, several acute and chronic inflammatory diseases, and cancer, conditions in which inflammation is an aetiopathogenic factor. Thus, ACE inhibitors and/or angiotensin-II receptor blockers could be of benefit in these conditions. Furthermore, structural analogues of ACE inhibitors and angiotensin-II receptor blockers could be developed that possess anti-inflammatory actions without significant action on the cardiovascular system.

A retrospective cohort design was used to study risk factors and cardiovascular end points among adults, with and without psychoses, receiving primary care. Earlier onset of risk factors and heart disease was noted among individuals with schizophrenia compared to those with affective psychoses and no disabilities. Patients with schizophrenia had increased relative risk for obesity, congestive heart failure, dementia, depression and death, while patients with affective psychoses had increased risk for dementia and diabetes.

An autopsy case of carbamazepine overdose with focal myocarditis is reported. The decedent was a 33-year-old female with a history of schizophrenia and bipolar disorder, who reportedly took 5-day dose of prescribed medications at around midnight. Although she stayed home following the direction of the physician, she was pronounced dead 8h after the intake. At autopsy she was obese, and her face was slightly swollen. The 420 g heart was free of coronary atherosclerosis, and the myocardium had no obvious scars. Both the left and right lungs were markedly congested and edematous. Strong congestion was also noted in the brain and visceral organs. Microscopic examination disclosed focal infiltration of inflammatory cells, most of which were lymphocytes, into the myocardium. In the toxicological analyses, carbamazepine concentration in the blood was 9.9 microg/ml, and other medications were below the toxic levels. It was considered that under the compromised cardiac function due to myocarditis presumably induced by some prescribed medications, and obesity, the carbamazepine overdose deteriorated her condition by triggering critical arrhythmia or congestive heart failure.

The use of atypical antipsychotic agents has rapidly increased in the United States and worldwide in the last decade. Nonetheless, many health care practitioners do not appreciate the significance of the cardiovascular side effects that may be associated with their use and the means to minimize them. Thus, atypical antipsychotic medications can cause cardiovascular side effects such as arrhythmias and deviations in blood pressure. In rare cases, they may also cause congestive heart failure, myocarditis, and sudden death. Patients with schizophrenia have a higher risk of cardiovascular mortality than healthy individuals, possibly because of excessive smoking, the underlying disorder itself, or a combination of both factors. Increased awareness of these potential complications can allow pharmacists and physicians to better manage and monitor high risk patients. Accurate assessments are very important to avoid medications from being given to patients inappropriately. Additionally, monitoring patients regularly via blood draws and checking blood pressure, heart rate, and electrocardiogram can help catch any clinical problems and prevent further complications. Finally, patient and family-member education, which pharmacists in particular can play key roles in, is central for the management and prevention of side effects, which is known to reflect positively on morbidity and mortality in these patients.

Despite substantial progress in the study of diabetes, important questions remain about its comorbidities and clinical heterogeneity. To explore these issues, we develop a framework allowing for the first time to quantify nation-wide risks and their age- and sex-dependence for each diabetic comorbidity, and whether the association may be consequential or causal, in a sample of almost two million patients. This study is equivalent to nearly 40,000 single clinical measurements. We confirm the highly controversial relation of increased risk for Parkinson's disease in diabetics, using a 10 times larger cohort than previous studies on this relation. Detection of type 1 diabetes leads detection of depressions, whereas there is a strong comorbidity relation between type 2 diabetes and schizophrenia, suggesting similar pathogenic or medication-related mechanisms. We find significant sex differences in the progression of, for instance, sleep disorders and congestive heart failure in diabetic patients. Hypertension is a highly sex-sensitive comorbidity with females being at lower risk during fertile age, but at higher risk otherwise. These results may be useful to improve screening practices in the general population. Clinical management of diabetes must address age- and sex-dependence of multiple comorbid conditions.
