Effectiveness of transcutaneous electrical nerve stimulation (TENS) for analgesia during biliary lithotripsy.

The effectiveness of transcutaneous electrical nerve stimulation (TENS) in controlling pain during biliary extracorporeal shockwave lithotripsy (BESWL) was assessed in 100 patients with symptomatic gallbladder calculi. Patients were divided into four groups: TENS electrodes were placed on the back at cutaneous anesthesia sites and on the right leg and the gallbladder acupuncture site in groups A and B. Electrodes were "turned on" only in group A. In groups C and D, electrodes were placed only on the back at cutaneous dermatomes. Electrodes were "turned on" in group C only. The TENS unit was stimulated at the pulse rate of 60 to 100 microseconds and frequency of 80 to 125 Hz. Lithotripsy was performed with the Lithostar Plus overhead module. The differences in the amount of analgesic used and the pain experiences by the patients in all groups were not statistically significant. The proportion of patients requiring intravenous analgesia in each group was also not significantly different (72%, 80%, 68%, 76% in groups A to D, respectively). Thus, TENS did not help in reducing the amount of intravenous analgesia required or the average pain perceived by the patient during lithotripsy treatment.

Analgesia

[Aggressive behavior in the psychiatric clinic].

Self and other directed violence of male psychiatric patients have been registered. The diagnostic analysis revealed an unequivocal correlation to delusional diseases and cerebroorganic hamper. Few patients caused a high percentage of all registered aggressions. Due to limited possibilities of drug treatment, changes of organization of communication and of the socio-organisational framework are aspired for the future.

[Monozygotic twins with schizoform psychosis and hypothalamic-induced hypogonadotropic hypogonadism].

It is reported about an uniovular male pair of twins which has been permanently hospitalized because of an intermittently progressing schizoform psychosis. A hypothalamically conditioned hypogonadotropic hypogonadism provable beyond that substantiates the possibility of the common causal genetic embodiment of both the clinical pictures which is disputed in literature.

Diseases in Twins

[Electroconvulsive treatment of psychotic patients with organic brain damage].

It is reported about 2 patients in whom the decision on electroconvulsive therapy was rendered more problematic by proven organic defects of the brain or a seizure disease. In our opinion, the electroconvulsive therapy is, in exceptional cases, also practicable under these conditions after an exact risk-benefit analysis.

Dynamic fluorescence measurements on the main phase transition of dipalmytoylphosphatidylcholine vesicles.

The kinetics of the main phase transition in dipalmytoylphosphatidylcholine (DPPC) vesicles have been investigated using our iodine laser-T-jump technique with fluorescence detection. A set of three fluorescent probes has been used to sense different parts of the bilayer hydrocarbon chain region. The well established membrane probes DPH and TMADPH as well as DPHPC, a labelled DPPC molecule. We report three relaxation signals in the microseconds and ms time range, which are detected with all three probes. This result supports our model of the main phase transition in DPPC vesicles.

The influence of cholesterol on the main phase transition of unilamellar dipalmytoylphosphatidylcholine vesicles. A differential scanning calorimetry and iodine laser T-jump study.

The influence of cholesterol (CHOL) on the main phase transition in single shell dipalmytoylphosphatidylcholine (DPPC) vesicles was investigated in equilibrium and kinetic experiments. CHOL increases the optical density and causes a slight hysteresis in turbidity transition curves. Static fluorescence anisotropy measurements showed interesting differences for three probes sensing different parts in the hydrophobic region of the phospholipid bilayer. Differential scanning calorimetry (DSC) peaks can be separated into a narrow and a broad component. The narrow component, which decreases linearly with increasing CHOL content and disappears at 20 mol %, is attributed to the transition of free phospholipid, while the broad component, being associated with the transition of CHOL-lipid units, increases monotoniously from 0 to 20%. Kinetic experiments were performed on our iodine-laser T-jump arrangement with turbidity detection. Three cooperative relaxation signals in the microsecond and millisecond time range were detected for pure DPPC vesicles as well as vesicles containing 7.5 and 16.5 mol % CHOL. All three relaxation processes were changed by CHOL: the superposition of the three relaxation amplitudes can be separated into a narrow and a broad component, as in DSC experiments. A speculative model is presented which assumes an inhomogeneous CHOL distribution fluctuating on a millisecond time scale in the temperature region of the main phase transition.

[Multidimensional studies of circadian biorhythm in psychoses].

Subject of the report is methodics for a circadian analysis in case of psychotical diseases. Acquisition and filing of psychopathological phenomenona is effected by means of Strukturiertes Psychopathologisches Erfassungssystem (SPES) and other self-or outside-rating-scales. The diurnal variation of body-temperature is taken as physiological reference function. The results of the analysis, which show an internal rhythmic desynchronization in case of phasic as well as in case of non-phasic psychoses, are given by way of exemplary instances.

[Side effects of bilateral electroconvulsive therapy--comparative clinico-computer tomographic study].

The side effects of a five-times bilateral electric shock therapy were clinically and computer-tomographically investigated. A connection exists between the number of electric shock treatments which are carried out and the expression of a transitory organic psychosyndrome. However, no significant differences in relation to the initial findings were established a week after the completion of the treatment series despite great interindividual differentiation. Neither cerebral oedema or other signs of disturbances were computer-tomographically detectable as results of treatment. CT and clinic findings do not correspond to each other.

[Electronic data processing-assisted epicrisis in clinico-psychiatric documentation of findings].

The medical profession is using computers to an increasing extent, and the graphic epicrises described here, which is intended mainly to augment the conventional epicrisis, is another useful application. It is based on a standardised psychopathological examination and documentation procedure and permits the course of psychopathological syndromes to be demonstrated in an illustrative way.

[Multiple recurrence in progressive paralysis].

In case of progressive paralysis of the insane, repeated recurrence can be explained only by the survival of pathogens inspite of optimal therapeutic conditions, the persistence of the pathogens being possibly produced by turning of the treponemas into L-type forms. In order that the possibilities and limits of recurrence verification will become apparent, reference is made to humoral and immunological changes of state given by way of example.
