Abdominal pain in neutropenic patients.
The records of 50 patients with abdominal pain and severe neutropenia were retrospectively reviewed to identify factors that may have influenced survival and surgical decisions. Ninety-two percent of these patients had hematologic malignant neoplasms. The patients were divided into four groups: 23 treated nonsurgically who died in the hospital, 10 treated nonsurgically who survived, 10 treated surgically who survived, and 7 treated surgically who died. Abdominal distention was the only symptom or sign found to be associated with mortality. Ninety-five percent of survivors recovered their white blood cell count above 1.0 x 10(9)/L, while 70% of nonsurvivors did not. No symptom or sign was found to be pivotal in the decision for or against surgical intervention. Overall, 60% of the patients in this series died. Thirty-four percent of patients underwent a surgical procedure, the majority of whom survived. We designed an algorithm for the evaluation and treatment of neutropenic patients with abdominal pain.

Vocational adjustment and general well-being of young adults with IDDM.
The vocational experiences and general well-being of 58 young adult subjects (mean age 24.3 yr) with insulin-dependent diabetes mellitus (IDDM) diagnosed during their adolescence were compared with that of 55 healthy matched control subjects with linear logistic discriminant function analyses. Assessment measures included the Rand General Well-Being Scale and the Rand Functional Limitations and Physical Abilities Batteries. Diabetic subjects, on average, reported significantly lower general well-being than control subjects, particularly in terms of health-related fears and feelings of depression. However, diabetic subjects did not report a pervasive functional deficit relative to control subjects and experienced similar employment rates and problems in the workplace. These results suggest that this group of young adult diabetic subjects has adjusted well to the demands of the workplace despite lower reports of general well-being. The results are discussed in light of relevant sampling issues.

Splenectomy in advanced chronic lymphocytic leukemia.
Between February 1972 and February 1989, splenectomies were performed in 30 patients with chronic lymphocytic leukemia (CLL) and three with prolymphocytic leukemia (PLL) at our institution. Indications for splenectomy included anemia and/or thrombocytopenia (hypersplenism) in 31 patients and symptomatic splenomegaly in two patients. Median time from the diagnosis of CLL to splenectomy was 25 months. Twenty (87%) of the 23 patients splenectomized for thrombocytopenia with or without anemia had platelet increments of greater than or equal to 50 x 10(9)/liter. Hemoglobin increments of greater than or equal to 3 gm/dl were noted in 12 (71%) of 17 patients splenectomized for anemia with or without thrombocytopenia. The median duration of platelet response was 18 months for 19 evaluable patients, and the median duration of hemoglobin response was 62 months for 10 evaluable patients. Median survival time from splenectomy was 36 months. Median survival from diagnosis was 103 months for 10 patients with stage III or IV disease at diagnosis and 79 months for 10 patients with stage II. A prospective study of the effect of splenectomy in a larger number of patients with advanced CLL should be considered.

Long-term vocational adjustment of cancer patients diagnosed during adolescence.
Long-term vocational achievements of 40 survivors of cancer diagnosed during adolescence were examined and compared with 40 healthy sex-matched and age-matched controls. Patients' ages at diagnosis ranged from 13 to 19 years (mean, 16.15). Study subjects had survived cancer for over 5 years and were on no cancer therapy. Assessment measures included the Rand General Well-Being Scale, the Rand Functional Limitations and Physical Abilities Batteries, and a semistructured interview. The relation of physical disability and limitations caused by cancer to patients' achievements also was evaluated. Although cancer patients, on the average, were more concerned about their health and reported lower general spirits than controls, no differences were found between control and study groups with regard to overall general well-being. More cancer patients than controls reported that their health limited their ability to engage in vigorous activities. A greater functional deficit was found among unemployed than employed cancer patients. Employers and co-workers often were aware of the patient's diagnosis (85% and 67%, respectively). Cancer patients reported disease-related discrimination in hiring (7.4%), induction into the military (66.7%), and obtaining health, life, and disability insurance (31.5%). There was no significant relationship between health status and employment. Nevertheless, cancer patients had a higher average income than controls. Sixty-four percent of patients believed that changes in certain physical features of the workplace were necessary to facilitate readjustment to the job. Despite the disabilities experienced by cancer patients and generally negative public attitudes, long-term survivors have a good outlook on life and are competitive members of the workplace and society.

The effect of technical factors on the quality of pulmonary venous flow from the transverse and longitudinal imaging planes with transesophageal echocardiography.
Right and left upper pulmonary venous flow is usually assessed with monoplane transesophageal echocardiography (TEE) in the transverse imaging plane. Pulmonary venous flow in the transverse imaging plane may be relatively difficult to record because of the larger angle between the pulmonary vein and the transducer beam. To compare the quality of echocardiographically derived Doppler flows of the right and left upper pulmonary veins between the longitudinal and transverse imaging planes with TEE, we performed pulsed-wave Doppler TEE of both upper pulmonary veins in transverse and longitudinal imaging planes in 36 patients with various diseases. We also recorded a quality index for each flow profile and the angle between the transducer beam and the pulmonary vein. The quality index of the left pulmonary venous flow assessed with the longitudinal and transverse imaging planes was similar in 35 (95%) of 36 patients, whereas the longitudinal imaging plane was superior to the transverse plane in one patient (3%). In contrast, the quality index of the right pulmonary venous flow assessed with the longitudinal and transverse imaging planes was similar in only 19 (53%) of 36 patients, whereas in 17 patients (47%) the longitudinal imaging plane was superior to the transverse imaging plane. The quality index had a significant effect on the Doppler flow recordings; suboptimal-quality flow recordings significantly underestimated the pulmonary venous diastolic flow integrals. The left atrium was larger in those patients with unobtainable flows than in those patients with exclusively obtainable flows (p < 0.001). The angle between the sample volume and the right pulmonary vein was larger in the transverse imaging plane than in the longitudinal plane (p < 0.001). In conclusion, the longitudinal imaging plane is generally superior to the transverse imaging plane for assessing right pulmonary venous flow and is recommended for performing a comprehensive assessment of pulmonary venous flow. The ability to obtain quality images and accurate assessment of flow may be related to the size of the left atrium and angle of the pulmonary vein.

Experimental and numerically modeled effects of altered loading conditions on pulmonary venous flow and left atrial pressure in patients with mitral regurgitation.
Pulmonary venous flow measured by pulsed-wave Doppler transesophageal echocardiography reflects the effects of mitral regurgitation on left atrial pressure contour. To assess the relationship between pulmonary venous flow and left atrial pressure in patients with mitral regurgitation under altered loading conditions, we studied 25 patients with 3+ or 4+ mitral regurgitation and a control group by measuring pulmonary venous flow with transesophageal echocardiography and left atrial pressures after administering saline solution (n = 6), nitroglycerin (n = 6), phenylephrine (n = 6), or nitroprusside (n = 7). After administration, the left atrial pressure v wave increased in the group given phenylephrine, concomitant with an increased diastolic flow. In contrast, the left atrial pressure v wave decreased in the group given nitroglycerin, concomitant with a decreased diastolic flow. Changes in diastolic flow were closely related to changes in the left atrial pressure v wave under all loading conditions (r = 0.91; p < 0.0001). Numeric modeling of left atrial pressure and pulmonary venous diastolic flow corroborated the experimental findings. We conclude that changes in pulmonary venous diastolic flow are closely related to changes in the left atrial pressure v wave in mitral regurgitation, under altered loading conditions.
