The epidemiology of psychosis: the Suffolk County Mental Health Project.

This article describes the rationale, aims, and methodology of an epidemiological study of psychosis being conducted in Suffolk County, New York. A sample of first-admission patients is drawn from 10 inpatient and 25 outpatient facilities. Diagnostic psychosocial interviews are conducted shortly after admission to treatment, and at 6- and 24-month followup. Consensus diagnoses are made after each interview. Demographic and clinical background characteristics of the first 250 subjects enrolled over a 2-year period are presented here. The response rate was 76 percent. Based on the initial interview, 75 percent of subjects received a diagnosis involving psychosis. The three most common diagnoses were schizophrenia, bipolar disorder with psychotic features, and major depression with psychotic features. Among subjects with psychosis, 58 percent of males and 29 percent of females had a history of substance abuse/dependence. Gender differences were found on several background and clinical characteristics. Males were somewhat younger, less likely to have ever married, and had less education. Although the median length of hospitalization was the same for females and males (27 days), females were more likely to be hospitalized within 1 month of the occurrence of their first psychotic symptom (60% of females compared to 37% of males). Subjects with schizophrenia-related disorders were significantly more impaired on an assessment of negative symptoms than were affectively ill subjects, but clinical ratings of depression were not significantly different across diagnostic groups.     

Development of leukemia after doxorubicin and cisplatin treatment for ovarian cancer

Alkylating agents have been the major group of chemotherapeutic agents associated with an increased incidence of secondary leukemias. In ovarian cancer alkylating agents have resulted in a lesser, although still increased, risk of secondary malignancies. This paper reports two cases of ovarian cancer treated with cisplatin and doxorubicin (Adriamycin, Adria Laboratories, Columbus, OH), and the subsequent development of an acute nonlymphocytic leukemia and a preleukemia syndrome. This regimen does not contain alkylating agents, and has not been associated with leukemia in patients with ovarian cancer. In these two cases, abnormalities of chromosomes 5, 7, 11, and 17 are reported which have been shown to occur in therapy-related leukemia.     

Epidermal growth factor excretion in burned rats

Evidence for epidermal growth factor (EGF) involvement in the physiological response to burns was sought from urinary levels of EGF, urea and creatinine in male rats using a standardized thermal skin injury model (25 per cent body surface) and treated with fluid resuscitation. Postmortem, the skin lesions were studied by microscopy to guarantee the absence of inflammatory complications. Statistically significant differences were observed in body weight, urea and creatinine excretion when compared to the basal values. When EGF excretion results were evaluated as raw data (expressed as ng/mg of creatinine or ng/day) compared to basal levels, no statistically significant differences were observed. However, when the results were expressed as percentage increases with respect to the basal values, a statistically significant increase was found over the first 7 days postinjury (P = 0.029).     

Aberrant hormone production from ovarian neoplasms: Strategies for diagnosis and therapy

Syndromes involving peptide or nonsex steroid hormone secretion due to aberrantly located tumors are rare. We report a collected series of 16 patients with ectopic hormone production from ovarian neoplasms, including 3 patients recently encountered at our institution as well as 13 additional cases identified in the recent literature. These tumors included 2 insulin-producing ovarian carcinoids, 1 ACTH-producing pituitary adenoma within a benign ovarian cystic teratoma, 2 cortisol-producing ovarian neoplasms, 8 gastrin-producing ovarian cystadenomata or cystadenocarcinomata, and 3 thyroxine-producing ovarian strumal carcinoids. All patients presented with syndromes of hormone excess. Only 62% of all tumors were localized preoperatively. Following ovarian resection, 87% of patients remained disease-free with a median follow-up period of 1.5 years. In addition to ovariectomy, 8 additional unnecessary ablative procedures were performed in 7 patients. These included distal pancreatectomy, pancreaticoduodenectomy, adrenalectomy, total gastrectomy, selective vagotomy, and subtotal thyroidectomy. Failure to localize the ovarian neoplasm preoperatively was associated with a significantly higher risk of subsequent unnecessary ablative procedures. Because of the potential for the ovary to act as a source of aberrant hormone secretion, we recommend complete preoperative evaluation of the pelvis in female patients presenting with nonlocalizable endocrine tumors.

Resumen Los síndromes relacionados con la secreción de péptidos o de hormonas esteroideas no sexuales por tumores de ubicación aberrante ocurren infrecuentemente. En este artículo reportamos una serie de 16 pacientes con producción hormonal ectópica por neoplasmas ováricos, la cual incluye 3 pacientes vistos recientemente en nuestra institución y 13 identificados en la literatura médica de los últimos años. El grupo incluye 2 carcinoides ováricos productores de insulina, 1 adenoma pituitario productor de ACTH, 2 neoplasmas ováricos productores de cortisol, 8 cistadenomas o cistadenocarcinomas ováricos productores de gastrina, y 3 carcinoides ováricos estrumales productores de tiroxina. Todas las pacientes se presentaron con síndromes de exceso hormonal. En sólo el 62% de los tumores se pudo establecer la ubicación anatómica en la fase preoperatoria. Después de realizada la resección del ovario, 87% de las pacientes permanecieron libres de enfermedad en el período de seguimiento, que fue de 1.5 años en promedio. Además de la resección ovárica, se practicaron otros 8 procedimientos adicionales innecesarios en 7 pacientes. Estos incluyeron pancreatectomía distal, pancreatoduodenectomía, adrenalectomía, gatrectomía total, vagotomía selectiva, y tiroidectomía subtotal. La falla en la localización preoperatoria del neoplasma ovárico apareció asociada con un riesgo aumentado de ulteriores procedimientos quirúrgicos innecesarios. En vista de la potencialidad del ovario de actuar como fuente de secreción hormonal aberrante, nosotros recomendamos una completa evaluación de la pelvis en las pacientes femeninas en quienes se diagnostiquen tumores endocrinos no localizables.

Résumé Les syndromes concernant la sécrétion d'hormones peptidique ou stéroïde nonsexuelle due à des tumeurs ectopiques sont rares. Nous rapportons une série de 16 patientes avec une production d'hormone ectopique provenant de néoplasmes ovariens, comprenant 3 patientes récemment soignées dans notre établissement ainsi que 13 cas supplémentaires relevés dans la littérature récente. Ces tumeurs comprennent 2 tumeurs carcinoïdes ovariennes productrices d'insuline, 1 adénome hypophysaire producteur d'ACTH à l'intérieur d'un tératome cystique ovarien bénin, 2 néoplasmes ovariens producteurs de cortisol, 8 cystadénomes ou cystadénocarcinomes ovariens producteurs de gastrine, et 3 carcinoïdes ovariens strumaux producteurs de thyroxine. Toutes les patientes avaient des syndromes d'hyperproduction hormonale. Soixante-deux pour cent seulement des tumeurs avaient été localisées en préopératoire. Après ovariectomie, 87% des patientes étaient apparamment sans récidive avec un suivi médian d'un an et demi. Cependent, outre l'ovariectomie, 8 interventions supplémentaires non nécessaires ont été accomplis chez 7 patientes. Celles-ci comprenaient: pancréatectomie distale, duodénopancréatectomie, surrénalectomie, gastrectomie totale, vagotomie sélective, et thyroïdectomie subtotale. L'impossibilité de localiser le néoplasme ovarien en période préopératoire était associée à un risque notoirement plus grand de faire une résection inutile. Compte tenu de la possibilité pour l'ovaire de se comporter en producteur de sécrétion ectopique d'hormone, nous recommandons un examen complet préopératoire du bassin chez les femmes se présentant avec des tumeurs endocrines non localisables.

Computed tomography of midline cysts of the prostate

Midline cysts in the male pelvis are a confusing entity due to their relatively infrequent presentation and the uncertainty as to their origin and classification. We report on CT appearance of four cases of midline prostatic cysts. Ultrasound correlation was available in one case. Two patients presented with lower urinary tract symptoms (hematospermia and/or hematuria), and two were asymptomatic, with one case detected on physical examination and one found incidentally on CT. Computed tomography demonstrated a characteristic sharply marginated, low density, homogeneous midline cyst within the prostate. On ultrasound a well defined midline anechoic cystic mass was seen. These cases are illustrated and a discussion of cystic masses in the male pelvis is included.     

Historical research methods in occupational therapy

This article discusses the process and methods of historical research in relation to occupational therapy. The paper reviews the process of writing history, including data gathering, organization, and interpretation as well as the responsibilities of the historical researcher. The authors propose that the methods of historical research can be used by occupational therapists as a means to develop a body of knowledge about the profession's history.     

The safety of awake tracheal intubation in cervical spine injury

As a referral centre for cervical spine injuries, we have routinely performed awake tracheal intubation when intubation was indicated. A retrospective case control study was undertaken to review the frequency of neurological deterioration and aspiration associated with our approach. Neurological deterioration was assessed by a change in level of injury or neurological grade at admission and discharge. Four hundred and fifty-four patients with critical cervical spine and/or cord injuries were reviewed over an eight-year period. A case group of 165 patients underwent tracheal intubation awake within two months of injury. A control group of 289 remained unintubated during the same period. A comparison of spinal neurological status between admission and discharge revealed no statistically significant difference in neurological deterioration between the two groups. This occurred despite a greater injury severity score in the case group. No evidence of aspiration during intubation was documented. We conclude that awake tracheal intubation is a safe method of airway management in patients with cervical spine injuries.
