The Texas Medication Algorithm Project Patient and Family Education Program: a consumer-guided initiative.

Educating patients with mental illness and their families about the illness and its treatment is essential to successful medication (disease) management. Specifically, education provides patients and families with the background they need to participate in treatment planning and implementation as full "partners" with clinicians. Thus, education increases the probability that appropriate and accurate treatment decisions will be made and that a treatment regimen will be followed. The Texas Medication Algorithm Project (TMAP) has incorporated these concepts into its philosophy of care and accordingly created a Patient and Family Education Program (PFEP) to complement the utilization of medication algorithms for the treatment of schizophrenic, bipolar, and major depressive disorders. This article describes how a team of mental health consumers, advocates, and professionals developed and implemented the PFEP. In keeping with the TMAP philosophy of care, consumers were true partners in the program's development and implementation. They not only created several components of the program and incorporated the consumer perspective, but they also served as program trainers and advocates. Initially, PFEP provides basic and subsequently more in-depth information about the illness and its treatment, including such topics as symptom monitoring and management and self-advocacy with one's treatment team. It includes written, pictorial, videotaped, and other media used in a phased manner by clinicians and consumer educators, in either individual or group formats.

Simultaneous correction of malrotation and gastroesophageal reflux in infants.

Gastroesophageal reflux (GER) is often associated with gastrointestinal malrotation in infants. Primary correction of the malrotation, reserving a secondary antireflux procedure for those patients with persistent symptoms of GER, is most commonly practiced. This decision is based on the notion that an antireflux procedure may be unnecessary and is associated with added morbidity. We retrospectively reviewed 12 infants with GER and malrotation. All infants had symptoms attributed to GER and/or malrotation. A control group of seven infants with malrotation only was included for comparison of operative duration and postoperative recovery. Infants who received concurrent Ladd and Nissen procedures (Group 1, n=8) had immediate resolution of symptoms. Infants treated by Ladd procedure alone (Group 2, n=4), had persistent symptoms, despite postoperative medical therapy. A subsequent antireflux procedure was necessary. Comparison of operative times showed that a simultaneous procedure added, on average, 35 minutes to the Ladd procedure. Postoperative feeding and hospital stay were comparable between Group 1 and the control group. In contrast, Group 2 patients had longer hospitalizations due to ineffective medical therapy for persistent GER. No significant morbidity was noted. We recommend comprehensive surgical treatment with concurrent Ladd and Nissen procedures. This approach provides expedient and effective treatment of GER and malrotation, with minimal increase in operative time and no increase in morbidity .

Radiation measurements aboard Spacelab 1.

The radiation environment inside Spacelab 1 was measured by a set of passive radiation detectors distributed throughout the volume inside the module, in the access tunnel, and outside on the pallet. Measurements of the low-LET (linear energy transfer) component obtained from the thermoluminescence detectors ranged from 102 to 190 millirads, yielding an average low-LET dose rate of 11.2 millirads per day inside the module, about twice the low-LET dose rate measured on previous flights of the space shuttle. Because of the higher inclination of the orbit (57 degrees versus 28.5 degrees for previous shuttle flights), substantial fluxes of highly ionizing HZE particles (high charge and energy galactic cosmic rays were observed, yielding an overall average mission dose-equivalent of about 150 millirems, more than three times higher than measured on previous shuttle missions.

Lymphocyte studies in a patient with chronic polyradiculoneuropathy.

We studied immunologic abnormalities in one patient with chronic polyradiculoneuropathy and the effects of immune suppression and plasmapheresis on the clinical course and immune abnormalities. Increased helper T cells and B cells with deficiency of T suppressor cells to B-cell but not to T-cell targets were detected. The patient's blood lymphocytes, but not the controls' lymphocytes, proliferated in vitro on culturing them with P2 antigen in the presence of the patient's CSF. Plasmapheresis combined with corticosteroid and azathioprine reversed the majority of immune abnormalities to normal but did not decrease the patient's lymphocyte-P2 proliferative response; nor did it improve clinical status.

Morphologic development of neonatal rat pinealocytes in monolayer culture.

The morphological development of pinealocytes maintained in monolayer culture, without the neural and humoral effects present in the developing rat has been studied and compared with the development that occurs in vivo. Pinealocytes in 5 day cultures contained organelles that were similar to those present in the pineals of intact 5 day old rats. However, light and dark cells were not noted in culture, and the cultured cells did not have the dense granules noted in vivo. As pinealocytes developed in culture, cytoplasmic processes increased in length and number. By 21 days of culture age, synaptic ribbons were found to have decreased in number, the difference between light cell and dark cell cytoplasm had become more prominent, and dense-cored vesicles had become more numerous, just as in the developing gland in vivo. These results suggest that the complex neural and humoral factors impinging upon the developing neonatal pineal in the intact animal may not be necessary for some aspects of its ultrastructural differentiation.

Effects of norepinephrine and dibutyryl adenosine 3',5'-cyclic monophosphate on the ultrastructure of pineal cells in monolayer culture.

To determine how neural influences control the function of the pineal gland, morphological and biochemical relationships after pharmacological treatment have been studied in rat pineal cells in monolayer cultures. Norepinephrine (NE) and dibutyryl cyclic 3',5'-adenosine monophosphate (dBcAMP) treatment of cells that had been in culture for 5 and 21 days produced a stimulation in the enzyme activity of serotonin N-acetyl transferase, an enzyme important in indole synthesis. NE and dBcAMP also produced morphological changes which were dependent on the time of cells in culture. When 5 day-cultures were treated with NE and dBcAMP, light and dark cells were noted and endoplasmic reticulum increased and became more organized. Only dBcAMP treatment at 5 days produced an increase in dense granules and an elongation of cytoplasmic processes. Treatment of 21 day-cultures with dBcAMP also produced an increase in cytoplasmic processes while treatment with NE produced an increase in the synaptic ribbons and clear vesicles within the processes.

Molecular forms of acetylcholinesterase in pineal cell and sympathetic neuronal cultures.

The activities of the various molecular forms of acetylcholinesterase (AChE) were measured in monolayer cultures of neonatal rat pineal cells grown alone and in co-culture with sympathetic neurons. AChE forms characterized by sedimentation coefficients of 4S, 6.5S, and 10S were found in he neuronal and pineal cultures, as well as in the co-cultures. The 16S AChE form was found only in the neuronal cultures. Total AChE activity increased with culture age in the co-cultures, but it decreased in pineal cells cultured alone. The low level of activity present in the neuronal cultures did not change markedly over the 27-day culture period. These results, which show bidirectional neuron-pineal cell effects, suggest that AChE molecular forms may be important markers to study the mechanisms underlying neuron-target cell interaction in the developing sympathetic nervous system.

Pineal cells enhance choline acetyltransferase activity in sympathetic neurons.

Cells derived from the neonatal rat pineal gland were cocultured with cells derived from neonatal rat superior cervical ganglia (SCG) in an attempt to determine whether a sympathetic target organ with only adrenergic properties could enhance the development of adrenergic transmitter properties in sympathetic neurons in tissue culture. Choline acetyltransferase was measured as an index of cholinergic differentiation, and tyrosine hydroxylase was measured as an index of adrenergic differentiation. As indices of total cell number and cellular volume, DNA and protein, respectively, were also measured. We found that the pineal-SCG cocultures contained ten times greater choline acetyltransferase activity than sister neuronal cultures cultured without pineal cells, thus indicating that the pineal cells enhanced cholinergic properties in the sympathetic neurons. This cholinergic enhancement was dependent upon the presence of nerve growth factor and could not be obtained with pineal-conditioned medium. Tyrosine hydroxylase activity, measured on cultures sister to those mentioned above, was low in all cultures and decreased somewhat in SCGs cultured alone. TH activity in the pineal-SCG cocultures, however, increased slightly. Some tyrosine hydroxylating activity developed in pineals cultured alone, however, and may have been responsible for the small increase in tyrosine hydroxylase activity noted in the pineal-SCG cocultures. The implications of these results for a determination of the role that target organ plays in the development of the transmitter properties of sympathetic neurons are discussed.

Effect of electromyographic feedback and static stretching on artificially induced muscle soreness.

Thirty-six male subjects aged 18 to 26 years were assigned at random to one of three treatment groups: biofeedback, static stretch, and control. Muscle soreness was produced in all subjects by an 80% maximal eccentric contraction of the biceps brachii. The subjects in the biofeedback group applied auditory electromyographic (EMG) feedback at 6, 25, 30, 49, and 54 hours after the exercise, and the stretch group applied static stretch to the exercised arm at the same time periods. Observations of EMG activity and perceived pain level were made immediately before and after exercise, and at 24, 48, and 72 hours following exercise. When compared with a control group, both auditory biofeedback and static stretching significantly reduced EMG muscle activity but had no significant effect on perceived pain. The EMG activity and perceived pain of the subjects in each treatment group significantly differed across observations.
