HUMAN LONGINGS AND MASCULINE TERRORS: MASCULINITY AND SEPARATION FROM MOTHER

ABSTRACT The paper explores two literary texts - Dostoevsky's novel Crime and Punishment and Euripides'play Bacchae - from the point of view of immature masculinity and the catastrophe that can follow if the boy fails to achieve a genuine separation from the maternal object. The author examines the masculine anxieties and defences that arise when the boy fails to work through the Oedipus complex and instead retreats to a dyadic relation with mother which excludes the father. This retreat involves a denial of reality and the creation of a paranoid world in which his own wishes to take possession of mother can be experienced by him as an intrusion by the mother into his own masculine identity and ultimately as castration by the mother. Attempts to resolve this threat to masculinity include the use of anal defences and tyrannical states of mind in the creation of a pseudo-masculinity.
The movement into the male Oedipus complex necessarily involves a psychological state in which the externality of the oedipal-object mother is continually in danger of being blurred by the shadow cast by the pre-oedipal mother. (Thomas Ogden 1992)     

Wasserstoffzahl und Säuregehalt des Schweißes bei chirurgischen Kranken

Zusammenfassung Die Wasserstoffzahl des Schweißes, der Gehalt an freien Wasserstoffionen, sagt nichts aus über die vorhandenen Säuren und Basen. Die Titrationsacidität, der gehalt des Schweißes an sauren und alkalischen Molekülen, wird durch Titration festgestellt. Wasserstoffzahl und Titrationsacidität im Spontanschweiß von Kranken unterscheiden sich wesentlich von P_H und Titrationsacidität im Wärmeschweiß von Gesunden. Der Spontanschweiß enthält bedeutend mehr Säure und alkalische Substanz; sein P_H bewegt sich in stätker sauren Bereichen und liegt oft tiefer als im Harn. Die Schweißfunktion ist eine Stoffwechselfunktion. Ursache der Schweißsekretion ist eine Stoffwechselstörung. Durch Schwitzen wird bei Bedarf das Stoffwechselgleichgewicht wiederhergestellt. Maßgebend für den Verlauf der Schweiß-P_H-Kurve ist die Intensität des schweißtreibenden Reizes und die Wirksamkeit des inneren Schwitzeffektes. Maßgebend für die Titrationsacidität ist der Allgemeinzustand, insbesondere die Leistungsfähigkeit der übrigen Stoffwechselorgane. Aus Qualität und Quantität des Schweißes können zuverlässige Schlüsse auf die vegetative Gesamtlage gezogen werden. Plötzlicher Absturz und ungewöhnlich hoher Anstieg der P_H-Kurve zeigen kritische Wendepunkte im Krankheitsverlaufe an. Kritische Schweiße und Nachtschweiße enthalten als titrierbare Substanz vorwiegend Säure, Todesschweiße und andere Erstickungsschweiße vorwiegend alkalische Stoffe in hoher Konzentration. Im einstündigen kritischen Schweiß können von Kranken mehr Säuren ausgeschwitzt werden, als im 24 Stundenharn durch die Nieren abgegeben werden. An der Heilwirkung der Schweißfunktion bei Krankheiten hat neben dem inneren Schwitzeffekt, der Vernichtung von Stoffwechselprodukten und Giften im Körper, der äußere Schwitzeffekt, die Ausscheidung von Säure, Toxin, Wasser und Salzen entscheidenden Anteil.Mit 10 Textabbildungen.     

Treatment of a recurrent inguinal lymphocele in a penis cancer patient by lymphography and selective ligation of lymphatic vessels

We report a case of recurrent inguinal lymphocele formation after inguinal lymphadenectomy treated by lymphographic mapping and selective ligation of the lymphatic vessels. Lymphographic mapping was performed by puncturing a lymphatic vessel at the dorsum of the foot. After isolating the vessels that drained into the lymphocele, they were clipped and divided through a small skin incision. The described technique showed an instant and complete suspension of the lymph secretion with subsequent complete healing. Lymphatic mapping and selective ligation of afferent lymphatic vessels proved to be an effective treatment of a recurrent inguinal lymphocele.     

Tumor necrosis factor-alpha in whole blood cultures of preeclamptic patients and healthy pregnant and nonpregnant women.

OBJECTIVES: Tumor necrosis factor-alpha (TNF-alpha) is recognized as a likely mediator of the excessive endothelial activation and injury that is a key pathogenetic mechanism of preeclampsia. We used whole blood cell cultures from 12 patients with severe preeclampsia and from 12 healthy pregnant and nonpregnant women to determine the release of TNF-alpha by unstimulated leukocytes as a measure of their state of activation, and their response to stimulation with lipopolysaccharide (LPS) as an indicator of their state of priming. METHODS: Blood was cultivated without and with LPS, and TNF-alpha release was measured after six and 24 hours of cultivation by enzyme-linked immunoassays. Differential leukocyte counts were performed, and TNF-alpha values calculated per 10(5) monocytes. RESULTS: In unstimulated whole blood cultures, TNF-alpha release after six hours of cultivation was similar in all three groups; but after 24 hours, TNF-alpha concentrations in culture supernatants from preeclamptic patients were significantly higher than were values obtained in blood from normotensive pregnant women. In LPS-stimulated blood cultures with a maximum of TNF-alpha release at six hours cultivation time, TNF-alpha concentrations were significantly lower in preeclamptic women than they were in both control groups. We showed in an additional experiment that a strong LPS challenge following preactivation with high doses of LPS resulted in reduced release of TNF-alpha compared with release of TNF-alpha following preactivation with low doses of LPS. CONCLUSIONS: The observed high capacity for spontaneous TNF-alpha release by leukocytes in preeclampsia indicates activation of TNF-alpha producing leukocytes by the disease process. Preactivation and exhaustion of leukocytes by leakage of TNF-alpha could lead to the reduced response to TNF-alpha inducer LPS as observed in blood cultures from preeclamptic patients.

Komplexverletzungen des Fußes

Complex injuries of the foot are often overlooked, especially in the multiple injured patient, and they then lead to major loss of function. When the mechanism of injury suggests involvement of the foot, a clinical examination of the lower extremities should be included in the primary diagnostic procedures implemented in the multiply injured patient, followed by radiological examination once the patient's condition is stable. The condition of the soft tissues is of decisive importance in the prognosis of complex foot injuries, regardless of whether the damage to the foot is one component of a polytrauma or an isolated injury, which can also be life threatening. The diagnostic examinations selected should be adapted to the severity of the injuries in the particular multiply injured patient. Successful therapy involves stable internal fixation of injuries to bones and joints, though the external fixation options should be considered in the first instance, and carefully selected methods of temporary and definitive soft tissue reconstruction. The aim of treatment is the best possible reconstruction of the foot as a functional weight-bearing unit with intact soft tissue cover and a natural form. Good results can be achieved when there is close interdisciplinary cooperation between trauma (orthopedic) and plastic surgeons. Patient with severe injuries of this kind should be transferred to a trauma center as the first step toward this end.     

In vivo muscarinic cholinergic receptor imaging in human brain with [11C]scopolamine and positron emission tomography.

Cerebral muscarinic cholinergic receptors were imaged and regionally quantified in vivo in humans with the use of [11C]scopolamine and positron emission tomography. Previous studies in experimental animals have suggested the utility of radiolabeled scopolamine for in vivo measurements, on the bases of its maintained pharmacologic specificity following systemic administration and the exclusion of labeled metabolites from the brain. The present studies describe the cerebral distribution kinetics of [11C]scopolamine in normal subjects following intravenous injection. Scopolamine is initially delivered to brain in a perfusion-directed pattern. After 30 to 60 min, activity is lost preferentially from cerebral structures with low muscarinic receptor density including the cerebellum and thalamus. Activity continues to accumulate throughout a 2 h postinjection period in receptor-rich areas including cerebral cortex and the basal ganglia. The late regional concentration of [11C]scopolamine does not, however, accurately parallel known differences in muscarinic receptor numbers in these receptor-rich areas. Tracer kinetic analysis of the data, performed on the basis of a three-compartment model, provides receptor binding estimates in good agreement with prior in vitro measurements. Kinetic analysis confirms significant contributions of ligand delivery and extraction to the late distribution of [11C]scopolamine, reconciling the discrepancy between receptor levels and tracer concentration. Finally, a novel dual-isotope method for rapid chromatographic processing of arterial blood samples in radiotracer studies is presented. The combination of rapid chromatography and compartmental analysis of tracer distribution should have broad utility in future in vivo studies with short-lived radioligands.     

Effectiveness of a Multidisciplinary Education Protocol in Children with Asthma (0-4 Years) in Primary Health Care

This paper describes the results of an asthma self-management protocol delivered to parents of children aged 0-4 years. The protocol was delivered by general practitioners (GPs), community nurses, asthma nurses, and doctors in child health centers. It consisted of 16 educational modules developed after an initial needs assessment of parents and a task analysis of primary care practitioners. The program was evaluated by means of an experimental design. Parents participating in the program had significantly more knowledge, a more favorable attitude toward asthma, and a higher self-efficacy score with respect to performing asthma self-management behaviors. Also, they reported performing self-management behaviors more frequently than parents in the control group. One-year follow-up results, which were collected for parents in the treatment group only, showed that the described changes were sustained. Further, the treatment group was found to have decreased its emergency and nonemergency use of the physician's office and to have a reduction in (reported) asthma severity. Process evaluation indicated that most modules were provided by the GPs to nearly all parents. After parents had read the modules at home, almost all the information was discussed in the next contact. GPs seldom referred patients to the community nurses, although this was suggested in the protocol.
