[Effects of slow-stroke massage as complementary treatment of depressed hospitalized patients].

BACKGROUND AND OBJECTIVE: Among methods of complementary treatment of depression, massage plays an important role, at least in the U.S.A. Although there are some pointers to the antidepressive and anxiolytic action of slow-stroke massage in various randoms studies of patient cohorts, there have been no controlled trials of depressed hospitalized patients. PATIENTS AND METHODS: 32 depressed patients (24 women, 8 men; average 48 years - coveringthe entire spectrum of affective disorders listed in the ICD but without comorbidity in axis 2) with a minimum BRMS score of 16,7 - were included in the study. The randomized cross-over trial involved three massage sessions at set times (M) and sessions in two control groups (C) (relaxation and perception) lasting for 60 min 2-3 days apart. Under the control conditions there was no touching. The effects of depression-specific variables (e.g. mood, drive, abnormal cognition, as well as typical progress variables of the slow-stroke massage (bodily awareness, general state of health, etc.) were measured by both the patients' own assessment and that of an independent observer. RESULTS: Under condition of both M and C, comparison of before and after effects, there was not only the primarily postulated mood-enhancing effect, but also some very marked changes in almost all dimension, the mean improvement ratio under M often being stronger than under C. After Bonferroni correction for multiple tests, the statistical significance there remained the stronger effect of M in four dimensions (global tenseness, restlessness, depressed mood, neck/shoulder tension). The intensive effect of M compared with C was confirmed by both female and male patients regarding the answers to various open questions. CONCLUSIONS: Slow-stroke massage is suitable for adjuvant acute treatment of patients with depression. It is very readily accepted also by very ill patients. In relation to the skin as an organ that aids identity, non-hedonic depressed patients are able to recognize the sensory quality of therapeutic touching as a positive stimulus. In view of the latent period of many weeks and the only moderate efficacy of antidepressants, the described complementary method, which does not require physiotherapeutic training, should be more often applied in both a hospital and general practice setting.

[Normalization of the Brief Repeatable Battery of Neuropsychological tests (BRB-N) for German-speaking regions. Application in relapsing-remitting and secondary progressive multiple sclerosis patients].

The Brief Repeatable Battery of Neuropsychological Tests (BRB-N) is a neuropsychological screening battery, often applied in multiple sclerosis (MS) patients. It is almost exclusively administered in trials and not in the daily practice routine because of the lack of normative values. Using a stepwise linear regression analysis, the dependence of test results on age, gender, and education of 241 healthy control subjects was investigated. Z-values of -1.68 or less were considered pathological. Based on the normative values, the proportions of cognitively impaired patients with relapsing-remitting MS (RRMS, n=43) and secondary progressive MS patients (SPMS, n=60) were calculated. The regression model explained 2.7-25.0% of the variance of test performances. Cognitive impairment occurred in 38% and in 47% of the RRMS and the SPMS groups, respectively. In both groups attention and concentration impairment was prominent, while in the SPMS group memory was also frequently affected. The proportion of cognitively impaired MS patients reflected the figures that could be found in the literature.

Genetic study of the CD36 gene in a French diabetic population.

OBJECTIVES: CD36 is a multifunctional membrane receptor widely expressed in different tissues which binds and internalizes oxidized low-density lipoprotein. In rodents, CD36 gene variations modulate glucose homeostasis and contribute to metabolic syndrome associated with type 2 diabetes but the effects in human are unknown. METHODS: We screened the entire coding sequence of the CD36 gene in 272 individuals and we genotyped both rare and frequent variants in 454 T2D subjects and 221 controls. RESULTS: We detected five mutations, P191P and N247S were only found each in one family and did not segregate with diabetes, the three others (A/C-178 in the promoter, A/G-10 in intron 3 and (GGGTTGAGA) insertion in intron 13) being equally frequent in diabetic subjects and in controls. However, adiponectin levels, a marker for insulin sensitivity, were significantly associated with the -178 A/C promoter variant allele (p=0.003, p corrected for multiple testing=0.036), possibly reflecting association with insulin-resistance in the French population. CONCLUSION: Thus, the -178 A/C SNP promoter mutation in the CD36 gene represents a putative genetic marker for insulin-resistance in the French population, although it does not appear to contribute to the genetic risk for T2D.

[IgE allergy due to formaldehyde paste during endodontic treatment. Apropos of 4 cases: 2 with anaphylactic shock and 2 with generalized urticaria].

We report 4 cases of allergic reaction to formaldehyde-containing root canal sealant after endodontic care: 2 anaphylactic shocks and 2 local reactions with generalized urticaria. Allergic IgE mediated mechanisms were suggested by the clinical presentation, skin tests and high levels of anti-formaldehyde IgE. These infrequent but potentially severe reactions after canal treatment led us to examine the involved mechanisms, the diagnostic procedure and the possibility of prevention in odontostomatology.

Alternate finger tapping test in patients with migraine.

Migraine patients are thought to show some cognitive dysfunction and slight structural abnormalities in the white matter of the brain, whereas most patients with multiple sclerosis (MS) are known to have numerous white matter lesions, often affecting the corpus callosum. To demonstrate psychomotor dysfunction, an alternate finger tapping task (a-FTT) on a PC was administered to controls (n = 41), migraine patients (n = 25), and multiple sclerosis patients (n = 22). Five MS patients with secondary callosal atrophy detected by MRI were also investigated as a separate group. Significant slowing was demonstrated in migraine (P = 0.0005) and MS (P<0.0001). The poorest test results were found in patients with callosal atrophy. In summary, a-FTT on a PC is able to detect minimal psychomotor dysfunction in migraine.

Cloning and characterization of a murine SIL gene.

The human SIL gene is disrupted by a site-specific interstitial deletion in 25% of children with T-cell acute lymphoblastic leukemia. Since transcriptionally active genes are prone to recombination events, the recurrent nature of this lesion suggests that the SIL gene product is transcriptionally active in the cell type that undergoes this interstitial deletion and that the SIL gene product may play a role in normal lymphoid development. To facilitate studies of SIL gene function, we have cloned and characterized a murine SIL gene. The predicted murine SIL protein is 75% identical to the human gene, with good homology throughout the open reading frame. An in vitro translated SIL cDNA generated a protein slightly larger than the predicted 139-kDa protein. Although a prior report detected SIL mRNA expression exclusively in hematopoietic tissues, a sensitive RT-PCR assay demonstrated SIL expression to be ubiquitous, detectable in all tissues examined. Since the RT-PCR assay suggested that SIL mRNA expression was higher in rapidly proliferating tissues, we assayed SIL mRNA expression using a murine erythroleukemia model of terminal differentiation and found it to be dramatically decreased in conjunction with terminal differentiation. These studies demonstrate that the human SIL gene product is quite well conserved in rodents and suggest that the SIL gene product may play a role in cell proliferation.

Wound healing and wound management: focus on debridement. An interdisciplinary round table, September 18, 1992, Jackson Hole, WY.

A multidisciplinary panel of experts convened to discuss the basic concepts of prevention and treatment of pressure ulcers. Special emphasis was placed on four types of debridement: mechanical, surgical, autolystic, and enzymatic. Debridement of burns was also discussed. Team management by informed practitioners is vital to successful wound care and all treatments should be based on a holistic appraisal of patients and their individualized plans of care.

Protein import into yeast mitochondria: the inner membrane import site protein ISP45 is the MPI1 gene product.

Protein import across both mitochondrial membranes is mediated by the cooperation of two distinct protein transport systems, one in the outer and the other in the inner membrane. Previously we described a 45 kDa yeast mitochondrial inner membrane protein (ISP45) that can be cross-linked to a partially translocated precursor protein (Scherer et al., 1992). We have now purified ISP45 to homogeneity and identified it as the product of the nuclear MPI1 gene. Identity of ISP45 with the MPI1 gene product was shown by microsequencing of three tryptic ISP45 peptides and by demonstrating that an antibody against an Mpi1p-beta-galactosidase fusion protein specifically recognizes ISP45. Antibodies monospecific for ISP45 inhibited protein import into right-side-out mitochondrial inner membrane vesicles, but not into intact mitochondria. On solubilizing mitochondria, ISP45 was rapidly converted to a 40 kDa proteolytic fragment unless mitochondria were first denatured with trichloroacetic acid. The combined genetic and biochemical evidence identifies ISP45/Mpi1p as a component of the protein import system of the yeast mitochondrial inner membrane.

Inner membrane protease I, an enzyme mediating intramitochondrial protein sorting in yeast.

Several precursors transported from the cytoplasm to the intermembrane space of yeast mitochondria are first cleaved by the MAS-encoded protease in the matrix space and then by additional proteases that have not been characterized. We have now developed a specific assay for one of these other proteases. The enzyme is an integral protein of the inner membrane; it requires divalent cations and acidic phospholipid for activity, and is defective in yeast mutant pet ts2858 which accumulates an incompletely processed cytochrome b2 precursor. The protease contains a 21.4 kd subunit whose C-terminal part is exposed on the outer face of the inner membrane. An antibody against this polypeptide inhibits the activity of the protease. As overproduction of the polypeptide does not increase the activity of the protease in mitochondria, the enzyme may be a hetero-oligomer. This 'inner membrane protease I' shares several key features with the leader peptidase of Escherichia coli and the signal peptidase of the endoplasmic reticulum.
