Cardiac outputs of post-myocardial infarction patients during swimming and cyclic.

We compared the cardiovascular response of post myocardial-infarction (MI) patients and inactive normal subjects at submaximum and maximum intensities of tethered swimming and upright cycling. At any given oxygen uptake (VO2), the inactive normals had similar cardiac outputs (Q) and heart rates (HR) during swimming and cycling, whereas the post-MI patients had lower Q's and higher HR's during swimming compared to cycling. The maximum response of inactive normals were not significantly different during swimming and cycling, but during swimming the post-MI patients had a 21% lower VO2. The lower VO2 swimming was due to a lower Q. While swimming at any exercise rate including maximum, the stroke volume (VS) of the post-MI patients did not increase above resting VS seated. Therefore, any increase in Q during swimming was due solely to increases in HR. Since the HR's of the post-MI patients were not significantly different during maximum effort swimming and cycling, the intensity of swimming can be safely prescribed from the maximum HR achieved cycling.

Prognostic classification of Hodgkin disease in pathologic stage III, based on anatomic considerations.

Fifty-two patients with pathologic stage III Hodgkin disease were studied in an effort to determine whether location of involved abdominal nodes influenced survival. Treatment consisted of total nodal radiotherapy with or without subsequent combination chemotherapy. Th initial radiation field was the "extended mantle," which included supradiaphragmatic nodes, the splenic hilar area, and paraaortic nodes to the level of L2-L4. Subsequently, lower paraaortic and iliac regions were treated ("lower inverted Y"). Patients with disease limited to the spleen and/or splenic, celiac, or portal nodes ("anatomic substage" III1) had a more favorable 5-yr survival than did patients with involvement of paraaortic, iliac, or mesenteric nodes ("anatomic substage" III2): 93% versus 57%, respectively (p less than 0.05). The addition of combination chemotherapy to total nodal irradiation was associated with improved survival of patients in stage III2, but not of those in stage III1.

Student drug use: attitudinal, parental relations, and sex differences--a pilot study.

Student drug abuse and its relationship to attitudes held by the abuser, sex differences,and the abuser's relationship to his parents were studied. The Parent-Child Relations Questionnaire and four Smantic Differnetials regarding the "real" me, the perceived me, the immediate world and the drug addict were employed. Subjects were divided into present, past, and never users. Results indicated striking sex differences as well as differences between female present and never users with respect to all the attitudes investigated and the perceived relationship with the mother. It was hypothesized that the etiological factors surrounding female drug use may be psychodynamic in nature while the etiological factors for male drug use may be environmental.

Biochemical monitoring of the surgical patient.

The need for prognostic and biochemical monitors of cellular function becomes increasingly evident with the further elucidation of the metabolic pattern secondary to disease. Thus far studies have shown that lactic acid may be one of these biochemical parameters. Investigations are now in the process of defining other biochemical indicators of cellular dysfunction.

Septic complications following gastric surgery: relationship to the endogenous gastric microflora.

The microflora of the stomach is derived from both the ingestion of food and saliva and the reflux of proximal intestinal contents through the pylorus. Normally, this microflora is inhibited by gastric acid and normal gastric motility. In disease states, however, such as bleeding or obstructing duodenal ulcer, gastric ulcer or carcinoma, the level of gastric acid is reduced or the gastric motility is altered. Thus, endogenous microflora persists and often becomes the source of postoperative wound infections following gastric resection.

The team approach in a psychogeriatric unit.

The importance of a multidisciplinary team approach was recognized when a 14-bed short-term Psychogeriatric Unit was opened in a psychiatric hospital. The limited time available to the psychiatrist in charge placed a heavy clinical responsibility on the paramedical personnel who formed the team. Initially, role distinctions were kept vague and regarded as not overly important. Six months after the Unit opened, all the staff members filled out a questionnaire. They felt that communication within the team was good, that they could fulfill the role of primary therapist, and that they understood their own roles and those of others. All regarded the psychiatrist as the head of the team. The psychiatrist felt that he had the ultimate responsibility for over-all care of the patients, that any attempt ot blur roles caused problems, and that there had been a partial regression to more traditional patterns. Members of the Unit regarded themselves as a team, able to work together and pool skills in treating patients, and thus play a significant part in total care. This attitude proved more valuable than attempting to break away from the medical model or decrying the importance of roles.

[Soft contactlenses in general practice (author's transl)].

In contrast to the hard lenses the soft lens has enough permeability for oxygen and water-soluble substances, whereas high molecular substances, bacteria and virus cannot penetrate the soft lenses, so long as their surfaces are intact. The two principal production methods, the spin cast method and the lathe-turned method are compared. The duration of wearing of the soft lens depends on the deposits of proteins from the tears on the surface of the lens and the desinfection method. The daily boiling of the lenses shortens their useful life, while chemical desinfection causes besides bacteriolysis, damage of the corneal cell protein. The new cleaners on the base of proteolytic plant enzymes promise good results. For the optical correction of astigmatism with more than 1 cyl, soft lenses with conic outer surface are used or combinations of a soft and a hard lens (Duosystem). The therapeutic use of soft lenses has as aim: protection of the cornea against mechanical irritation, release of pain, protracted administration output of medicaments. Further indications for use: aseptic corneal inflammation and corneal defects.

[Osteopathies and calcium absorption in chronic liver diseases].

Enteral calcium absorption was determined in 18 patients with non-obstructive liver disease (16 with liver cirrhosis, 2 with chronic hepatitis). There was no significant difference in comparison with healthy persons. Osteoporosis in patients with chronic liver disease probably is not due to impaired calcium absorption but to other complications of liver disease as immobility, muscle atrophy, chronic pancreatitis, alcoholism and malnutrition. Osteomalacia on the other hand, is a complication of long standing obstructive liver disease. In these cases vitamin D treatment is indicated.
