We have found shortened survival in 200 schizophrenics, 100 manics, and 225 depressives by comparing them with the Iowa general population. The numbers of years of shortened survival were estimated from the survival curves of each diagnostic group by sex. Variables affecting shortened survival were diagnostic group, sex, age at admission, and pay status at admission. Excess causes of death were suicides, accidents, and infective and circulatory system diseases. The absolute mortality for deaths due to neoplasm in our sample was not significantly different than that in the Iowa general population. However, the proportional mortality from the same data showed a deficiency in deaths due to neoplasm in schizophrenia and affective disorders. Well-designed epidemiologic studies are needed to see if there is a real deficiency in deaths due to cancer in the major psychoses.

1. There are some remarkable analogies between neoplastic growth of tissue cells and other pathological events such as functional alterations of the central nervous system resulting in schizophrenic behaviour. 2. Body tissues in general and the central nervous system in particular are highly cooperative systems which can undergo state transitions at critical points. 3. Circadian rhythms may be regarded as giant fluctuations near a critical point. 4. Temperature shifts and changes of other environmental conditions can induce reversible state transitions whose occurrence is indeterminate but whose progress, once they have occurred, is inevitable. 5. Hypothermia may be a useful form of treatment of illnesses such as cancer, that can be reversed, since it is a mean of bringing a system back to its equilibrium. 6. If we assume that characters such as vitamin dependency are gentically transmitted we may envisage that homozygotes for that character have a phenotypic expression which may lead to high probabilities of developing schizophrenia and cancer at two different ages as a result of environment-dependent phase transitions.

The presentation shows the survey of diseases the pathogenesis of which might be connected with the existence of Heat Shock Proteins (HSPs). We discuss the data referring to the influence of the HSPs upon the occurrence and progression of the following diseases: systemic lupus erythematosus, reactive arthritis, rheumatoid arthritis, insulin dependent diabetes mellitus, schizophrenia and Alzheimer's disease. There is also indicated a possible activity of HSPs in the pathogenesis of neoplasia, organ ischaemia and inflammation or degeneration.

We reviewed 7 cases with posterior fossa structural abnormalities (3 tumors, 2 megacisterna magna and 2 Dandy-Walker syndrome) presenting with neuropsychiatric symptomatology. Derangement in the balance of dopamine, serotonin and noradrenergic networks has been implicated in the pathogenesis of schizophrenia, affective and even personality disorders. Disruption of the cerebellar output to mesial dopaminergic areas, locus coeruleus and raphe nuclei, or deafferentation of the thalamolimbic circuits by a cerebellar lesion may lead to behavioral changes. Seven patients (pts) (comprising 4 men and 3 women with mean age 22 years) were diagnosed as suffering from psychosis (2 pts), major depression (1 pt), personality disorders (2 pts) and somatoform disorders (2 pts) (DSM-IV criteria). Brain CT scan (7 pts) and MRI (4 pts) revealed tumors of the posterior fossa (2 pts), megacisterna magna (2 pts) and Dandy-Walker variant (2 pts). In one patient a IVth ventricle tumor was removed in childhood.

A report is presented of a follicular dendritic cell (FDC) tumor arising in the lymph nodes and inguen of a 55-year-old Japanese female, who had suffered from schizophrenia for 25 years. The left submandibular lymph nodes had completely lost their normal architecture, except for the capsule, due to tumor cell infiltration. Occasional nodular structures resembling epithelioid granulomas, attributable, at least in part, to follicular involvement of tumor cells, were observed. These nodules were composed of epithelioid- or fibroblast-like tumor cells forming interwoven fascicles, to which small lymphocytes were attached. Tumor cells were also scattered in the internodular areas. For more atypical tumor cells, arranged in a sheet-like structure, were present in the inguinal specimen, the tumor cells of which expressed Ki-M4p, CD21, CD35 and other antigens known to be expressed on FDC. Furthermore, they also expressed the monocyte/macrophage antigens, alpha 1-antitrypsin, alpha 1-antichymotrypsin, lysozyme, CD14, CD33, CD68 and Mac387 and fibroblastic antigen. Ultrastructural studies demonstrated lysosomal granules as well as a few desmosomes, indicating the tumor cells possessed fibrohistiocytic and FDC characteristics.

Invasion of the air passage, especially with intraluminal involvement of well-differentiated thyroid carcinoma, is rare. Establishing a patent airway before surgery is necessary, but difficult and risky. We report a case of thyroid cancer with intraluminal invasion of the trachea. A 62-year-old schizophrenic woman presented with blood-tinged sputum and dyspnea. She had undergone a thyroid lobectomy 8 years previously. Computed tomography and bronchoscopy showed a protruding mass in the upper trachea and limited movement of the bilateral vocal folds. Emergency tracheostomy was performed to relieve impending apnea. Fine-needle aspiration of the left protruding thyroid gland showed papillary carcinoma. Because the tumor diffusely infiltrated the thyroid gland and intermingled with fibrosis due to the previous thyroid operation, and because there was limited movement of bilateral vocal folds, the patient underwent total laryngectomy, total thyroidectomy, total parathyroidectomy, and tracheal resection. Neither radioactive iodine nor external irradiation were given because of anticipated poor compliance due to schizophrenia. The postoperative course was smooth and thyroid hormone and calcium were supplemented regularly. The patient has lived well and without local recurrence for more than 3 years since the operation. She can speak with an artificial larynx.

Folates function as a single carbon donor in the synthesis of serine from glycine, in the synthesis of nucleotides form purine precursors, indirectly in the synthesis of transfer RNA, and as a methyl donor to create methylcobalamin, which is used in the re-methylation of homocysteine to methionine. Oral folates are generally available in two supplemental forms, folic and folinic acid. Administration of folinic acid bypasses the deconjugation and reduction steps required for folic acid. Folinic acid also appears to be a more metabolically active form of folate, capable of boosting levels of the coenzyme forms of the vitamin in circumstances where folic acid has little to no effect. Therapeutically, folic acid can reduce homocysteine levels and the occurrence of neural tube defects, might play a role in preventing cervical dysplasia and protecting against neoplasia in ulcerative colitis, appears to be a rational aspect of a nutritional protocol to treat vitiligo, and can increase the resistance of the gingiva to local irritants, leading to a reduction in inflammation. Reports also indicate that neuropsychiatric diseases secondary to folate deficiency might include dementia, schizophrenia-like syndromes, insomnia, irritability, forgetfulness, endogenous depression, organic psychosis, peripheral neuropathy, myelopathy, and restless legs syndrome.

We report a case of glioblastoma manifesting 49 years after a lobotomy. He was diagnosed as having schizophrenia at age 20 and was operated on with a standard lobotomy when he was 27 years old. He had led a useful life after 40 years old without medication. Because of hallucination and delusion, he was hospitalized at the end of 1996. CT showed a well enhanced tumor adjacent to the cavity made by the lobotomy in the left frontal lobe. This is the second case report of glioblastoma just beside the cavity formed by lobotomy. The relationship between glioblastoma and old lobotomy is discussed, especially in regard to morphology and CT findings.

A 39-year-old man with schizophrenia and suicide attempt was diagnosed with stage IIb testicular tumor. He was initially admitted to the psychiatry ward and underwent high orchiectomy. After schizophrenia became stable by administration of antipsychopathic drugs, he was transferred to the ordinary urology ward and treated with 3 courses of chemotherapy (bleomycin, etoposide, cisplatin) and retroperitoneal lymph noded dissection. The mental status of the patient remained under good control throughout the course of treatment. He has been free of recurrence for 8 months postoperatively. We discussed general medical issues concerning the treatment of malignant diseases in patients with psychosis.
