Meningitis

The most frequent pathogens causing bacterial meningitis in Germany are Neisseria meningitidis, Streptococcus pneumoniae, Borrelia burgdorferi, Listeria monocytogenes and staphylococci. Since immunization against Haemophilus influenzae has become a routine vaccination procedure, this pathogen no longer plays a significant role in the etiology of bacterial meningitis. A number of pilot studies have indicated that selected PCR methods most probably represent the future etiological diagnosis of bacterial meningitis. The easiest and most rapid diagnostic method is, however, still a simple gram stain preparation. In fatal cases that ran a peracute course, especially in the Waterhouse-Friderichsen syndrome, only increased congestion of the surface of the brain is detectable at autopsy. In such cases, there is hardly any histological evidence of an inflammatory reaction of the leptomeninges. In cases of purulent meningitis, in addition to the typical infiltration of the subarachnoid space with abundant granulocytes, after some days of illness there is a wide-spread histomorphological picture of pathological alterations with fibrinoid vessel wall necroses, thromboses, ventriculitis, infarctions as well as venous and arterial vasculitis. The breakdown of the integrity of the blood-brain-barrier in bacterial meningitis is obviously due to a separation of intercellular tight junctions of the endothelium of the capillaries of the leptomeninges. The cause of death in meningitis, depending on the severity and duration of a concomitant sepsis, is an increase in intracranial pressure that leads to a circulus vitiosus (via a reduced central perfusion associated with metabolic acidosis) with cerebral vasodilatation. This is followed by an additional rise of intracranial pressure and finally a reduced cerebral blood supply and central dysregulation. The medico-legal expert is occasionally confronted with this topic against the background of a possible misjudgement of the disease due to insufficient diagnostics or delayed diagnosis and in the light of a posttraumatic or nosocomial origin of the illness.

Operative Versorgung von Achillessehnenverletzungen

Rupture of the Achilles tendon is typically associated with sportive activities with increasing tendency; it occurs most commonly in the third to fourth decade of life with a male-to-female ratio of 5–10:1. Ruptures are caused predominantly by a sudden, unexpected overextension of the tendon while direct trauma is less frequent. The recommended treatment of the injury remains controversial. In Germany, due to the good functional results, the open surgical repair represents the standard therapy since many years. The open suture technique offers the advantage of a lower re-rupture rate but is associated with the risk of wound-related complications including infection. By percutaneous suture techniques a significant decrease in the rate of infections and complications in wound healing could be achieved by minimal-access with reduced soft tissue trauma; on the other hand an increased rate of lesions of the sural nerve is reported. Dynamic imaging assessment of ultrasound or MRI allows a more accurate localisation of the ruptured ends of the tendons which is the prerequisite for the non-operative primary functional treatment of Achilles tendon ruptures. This conservative treatment regime is recommended when adaptation of the ends of the ruptured tendon is possible in 20° plantar flexion of the foot. Moreover, the desired level of daily activity and the patients’ degree of compliance has to be considered. Operative management should be avoided in the elderly patient or patients with risk factors like immunosuppressive therapy, diabetes mellitus, steroid use or failure to comply.     

Lebensentwürfe junger Frauen

Initially, data are presented which describe the difficulties which young women have in obtaining economic independence and earning their own living. Next, the vocational orientation of young women will be described. We hope to make clear that young women are more oriented towards grounding a family, in addition to making a career, than young men. The difficulties of having both children and a career will be discussed. Until now, an egalitarian responsibility of mother and father has not been reached. Mothers have the main responsibility in almost all cases. Finally, the article will list some urgent measures required to give women equal opportunities in work and to ease a young couple’s decision to have children.     

Präklinische Intubation

Endotracheal intubation is required in 5–10% of all prehospital emergencies. Poor environmental conditions (e.g. limited space, poor or excessive lighting etc.), unfavorable patient-related factors (e.g. trauma, bleeding, pulmonary aspiration etc.) and the pressure of time make prehospital airway management a challenging procedure even for experienced emergency physicians. The incidence of difficult endotracheal intubation is significantly higher than in-hospital. Profound clinical practice, recognition and adequate treatment of complications of intubation, and ongoing clinical practice are essential for successful and responsible prehospital airway management. A brief physical examination helps to identify predictors for difficult intubation, thereby modifying treatment strategies. Every emergency physician must be closely familiar with at least one supraglottic airway device and the recent algorithms to manage the unanticipated difficult airway.     

Heparininduzierte Thrombozytopenie

Heparin-induced thrombocytopenia (HIT) represents a serious side effect caused by an atypical immune response to platelet factor 4 leading to platelet activation and thrombin formation. These patients are at high risk of thromboembolism, with a rapid drop in platelet count between days 5 and 14 after the initiation of heparin treatment. In single cases, especially after major surgery, platelet count reduction might be absent or hidden by preceding thrombocytosis. Different clinical manifestations of HIT include unspecific skin reactions with potential necrosis at the site of heparin injection, mostly after the application of unfractionated heparin but also with low molecular weight heparin. In heparin-induced skin necrosis, administration of unfractionated or low molecular weight heparin is contraindicated and heparin therapy should be stopped immediately. Instead, an alternative anticoagulant in the form of a direct thrombin inhibitor such as argatroban, and respectively lepirudin, or danaparoid sodium must be administered. Due to frequent misinterpretations of heparin-induced unspecific skin reactions, especially in the absence of thrombocytopenia, we present two case reports which should increase the awareness of HIT’s various clinical pictures.     

Ultraschall in der Tumornachsorge

According to the guidelines, ultrasonography (US) is now established as the cross-sectional imaging technique of choice in postoperative care of colorectal carcinoma. Although conventional percutaneous US is inferior to computed tomography (CT) and magnetic resonance imaging (MRI) for detecting hepatic metastases, the application of specific contrast media has significantly increased sensitivity and specificity to 87% and 88%, respectively. The combination of US and CT/MRI achieves the highest detection rates. During follow-up of rectal carcinoma, in up to 20% of locoregional recurrences are diagnosed solely by endorectal sonography and result in repeat resection with curative intention. In noncolorectal carcinoma, US is recommended in the guidelines for following up hepatocellular carcinoma and malignant thyroid disease, but the available data are insufficient to support those recommendations.     

Maternal Position at Midwife‐Attended Birth and Perineal Trauma: Is There an Association?

ABSTRACT: Background: Most women will sustain some degree of trauma to the genital tract after vaginal birth. This study aimed to examine the association between maternal position at birth and perineal outcome in women who had a midwife‐attended, spontaneous vaginal birth and an uncomplicated pregnancy at term. Methods: Data from 3,756 births in a major public tertiary teaching hospital were eligible for analysis. The need for sutures in perineal trauma was evaluated and compared for each major factor studied (maternal age, first vaginal delivery, induction of labor, not occipitoanterior, use of regional anesthesia, deflexed head and newborn birthweight >3,500 g). Birth positions were compared against each other. Subgroup analysis determined whether birth positions mattered more or less in each of the major factors studied. The chi‐square test was used to compare categorical variables. Results: Most women (65.9%) gave birth in the semi‐recumbent position. Of the 1,679 women (44.5%) who required perineal suturing, semi‐recumbent position was associated with the need for perineal sutures, whereas all‐fours was associated with reduced need for sutures; these associations were more marked in first vaginal births and newborn birth weight over 3,500 g. When regional anesthesia was used, semi‐recumbent position was associated with a need for suturing, and lateral position associated with a reduced need for suturing. The four major factors significantly related to perineal trauma included first vaginal birth, use of regional anesthesia, deflexed head, and newborn weight more than 3,500 g. Conclusions: Women should be given the choice to give birth in whatever position they find comfortable. Maternity practitioners have a responsibility to inform women of the likelihood of perineal trauma in the preferred birth position. Ongoing audit of all clinicians attending births is encouraged to further determine effects of maternal birth position and perineal trauma, to investigate women's perception of comfortable positioning at birth, and to measure changes to midwifery practice resulting from this study.
