Dermatological and venereological expertise is indispensable for the medical care of our soldiers at home and during military missions and represents a major competence in military medicine. Therefore, in the new structure of the combined German Forces medical services, dermatological clinics have been set up at all Bundeswehr hospitals, which, as academic teaching hospitals, are regionally involved in the medical care of the civilian population. In addition to general dermatological and dermatosurgical care, wound treatment and tropical dermatology represent military medicine-related priorities. Dermatological clinics are maintained in an interdisciplinary network at the Bundeswehr hospitals in Berlin, Hamburg, Koblenz, Ulm, and Westerstede. Outpatient dermatological treatment facilities complete the medical care at numerous locations where troops are based.PURPOSE There is no study exploring the positional relationship between the external acoustic meatus (EAM) and the sigmoid sinus (SS) in detail. The present study aimed to characterize the relationship using contrast magnetic resonance imaging (MRI). METHODS In total, 85 patients with an intact EAM, SS, and surrounding structures underwent thin-sliced, contrast MRI. Imaging data were transferred to a workstation for analysis. RESULTS In all patients, the EAM and SS were well depicted on both the sagittal and axial images. The relationships and distances between the EAM and SS, in addition to the shape of cross sections of the EAM, were highly variable with left-right asymmetry. The positional relationships between the EAM and the anterior edge of the SS were classified into superior, intervening, and inferior types. The intervening type was the most predominant, accounting for 85%. The shortest distance between the posterior wall of the EAM and the anterior margin of the SS was 12.3 ± 3.9 mm on the right side and 13.0 ± 2.9 mm on the left. In three women, the distance was less than 5 mm on the right side. CONCLUSIONS The positional relationship between the EAM and SS is highly variable and inconsistent. These structures may be adjacent, especially on the right side, and presurgical contrast MRI should be included when planning surgeries around the EAM.Inherited or acquired mutations can lead to pathological outcomes. However, in a process defined as synthetic rescue, phenotypic outcome created by primary mutation is alleviated by suppressor mutations. An exhaustive characterization of these mutations in humans is extremely valuable to better comprehend why patients carrying the same detrimental mutation exhibit different pathological outcomes or different responses to treatment. Here, we first review all known suppressor mutations' mechanisms characterized by genetic screens on model species like yeast or flies. selleck compound However, human suppressor mutations are scarce, despite some being discovered based on orthologue genes. Because of recent advances in high-throughput screening, developing an inventory of human suppressor mutations for pathological processes seems achievable. In addition, we review several screening methods for suppressor mutations in cultured human cells through knock-out, knock-down or random mutagenesis screens on large scale. We provide examples of studies published over the past years that opened new therapeutic avenues, particularly in oncology.OBJECTIVE Although radiofrequency ablation is well validated for treatment of osteoid osteoma, newer technologies, namely cryoablation, have been less thoroughly studied. The purpose is to perform a systematic review and pooled analysis of percutaneous ablation technologies for treatment of osteoid osteoma with subset analysis of intra-articular and spinal tumors. MATERIAL AND METHODS A total of 36 of 79 identified manuscripts met inclusion criteria, comprising 1863 ablations in 1798 patients. Inclusion criteria were (1) retrospective or prospective analysis of thermal ablation of osteoid osteomas in any location, (2) at least 6 months of clinical follow-up, (3) 10 or more patients, (4) patients not included in a second study included in this review, and (5) English language or English translation available. Success rate was defined as all ablations minus technical failures, clinical failures, and recurrences. Subset analysis of intra-articular and spinal tumors was performed. RESULTS Overall success rate was 91.9% (95% CI 91-93%). Technical failure, clinical failure, and recurrence rates were 0.3%, 2.1%, and 5.6% respectively. Complications were seen in 2.5% (95% CI 1.9-3.3%) patients. There was no significant difference when comparing radiofrequency ablation and cryoablation (p = 0.92). Success rates for intra-articular (radiofrequency ablation) and spinal tumors (radiofrequency and cryoablation) were 97% and 91.6% respectively. CONCLUSION Percutaneous ablation of osteoid osteomas was highly successful with low complication rates. Efficacy of radiofrequency ablation and cryoablation is similar, which is consequential because cryoablation is associated with decreased pain, predictable nerve regeneration, and theoretical immunotherapy benefits. Treatment of more challenging intra-articular and spinal lesions demonstrated similarly high success and low complication rates.Acute eosinophilic pneumonia (AEP) is a rare disease characteristically involving eosinophilic infiltration of lung parenchyma as well as fever, dyspnea, and coughing. A differentiation is made between primary and secondary AEP depending on the underlying etiology. Substances that most frequently cause secondary AEP are antibiotics, such as the lipopeptide daptomycin. This is a case report about a 69-year-old female patient who underwent antibiotic treatment with daptomycin for an infection of a knee prosthesis. During the treatment, signs of pneumonia developed and included the increased dependence on mechanical ventilation of the previously intubated patient, infiltrates on a chest X‑ray, fever, and an increase in serum inflammation markers. Proof of bacteria as an underlying pathogen was not possible. A thoracic computed tomography (CT) scan showed opacities that are commonly seen in interstitial lung disease. Termination of daptomycin treatment due to renal failure led to an improvement of pulmonary symptoms.
