[Ruptured pulmonary Echinococcus granulosus cyst: A rare cause of severe pneumogenic sepsis]. / Rupturierte pulmonale Echinococcus granulosus-Zyste ­ Eine seltene Ursache für eine schwere pneumogene Sepsis.

Parasitic infections by Echinococcus granulosus are rare in Germany, and predominantly affect individuals with a migration background. Liver and lungs are the most commonly affected organs. Pulmonary cysts often remain asymptomatic until rupture, at which point symptoms may manifest. The diagnostic approach typically involves a combination of imaging modalities and serological tests, occasionally supplemented by molecular genetic methods. Given the global movements of migration, considerations of the epidemiology of common diseases in the country of origin should also be taken into account in the differential diagnosis. We present the unusual case of a pneumogenic sepsis in a young man from Syria, where the combination of medical history alongside radiological, serological, and molecular genetic investigations ultimately led to the diagnosis of a severe pulmonary echinococcosis with rupture.

[Spontaneous pneumomediastinum (Hamman's syndrome) with pneumorrhachis as a rare cause of acute chest pain in a young patient with acute asthma exacerbation]. / Spontanes Pneumomediastinum (Hamman-Syndrom) mit Pneumorrhachis als seltene Ursache für akuten Thoraxschmerz bei einem jungen Patienten mit akut exazerbiertem Asthma bronchiale.

Pneumomediastinum, defined as abnormal presence of air in the mediastinum, is a rare cause of acute chest pain. The condition may occur spontaneously as well as a secondary consequence of trauma or medical interventions. The spontaneous pneumomediastinum (Hamman's syndrome) is associated with a good prognosis, even without intervention. However, undelying severe conditions such as gastrointestinal perforations should be excluded. Diagnosis might be made using conventionell chest x-ray; a CT scan may give additional useful information. A subcutanous emphysema is a common finding in patients with pneumomediastinum. The presence of air in the epidural space of the spinal canal (pneumorrhachis) is a rarely seen but likewise mostly benign complication. We report a case of a young man with Hamman's syndrome and pneumorrhachis, provoked by acute asthma exacerbation; despite pronounced symptoms, his condition could be treated conservatively.

[Unusual presentation of late reactivated tuberculosis in immunosenescence after nine decades latency]. / Ungewöhnliche Spätmanifestation einer reaktivierten Tuberkulose in der Immunseneszenz nach 9 Dekaden Latenz.

INTRODUCTION: Tuberculosis is an often underestimated infectious disease which can lead to manifest infections even after years of latency. Pulmonary manifestations are by far the most frequent, although any other organ can be equally affected. HISTORY: A 95-year old patient presented with a localized painful swelling of the right foot for further investigation. Despite her advanced age there were no pre-existing medical conditions, except for a club foot existing since early childhood. FINDINGS AND DIAGNOSIS: On physical examination we found a hyperemic fluctuant swelling of 5 cm diameter at the arch of the right foot. The X-ray showed a complete destruction of the regular osseous structures from the upper ankle joint to the proximal metatarsal bones. THERAPY AND COURSE: Intraoperatively the suspicion of an abscess was confirmed and material was obtained for microbiological investigation. Liquid cultures grew Mycobacterium tuberculosis. In an MRI-scan, involvement of the tarsal and metatarsal bones could not be excluded, thus the duration of the standard antituberculose treatment was set to 9 months. CONCLUSIONS: Tuberculosis, primary or reactivated, should always be considered as a potential cause of unclear infections; especially in patients with anticipated immunosenescence.

Variation of vital signs with potential to influence the performance of qSOFA scoring in the Ethiopian general population at different altitudes of residency: A multisite cross-sectional study.

INTRODUCTION: The physiological range of different vital signs is dependent on various environmental and individual factors. There is a strong interdependent relationship between vital signs and health conditions. Deviations of the physiological range are commonly used for risk assessment in clinical scores, e.g. respiratory rate (RR) and systolic blood pressure (BPsys) in patients with infections within the quick sequential organ failure assessment (qSOFA) score. A limited number of studies have evaluated the performance of such scores in resource-limited health care settings, showing inconsistent results with mostly poor discriminative power. Divergent standard values of vital parameters in different populations, e.g. could influence the accuracy of various clinical scores. METHODS: This multisite cross-sectional observational study was performed among Ethiopians residing at various altitudes in the cities of Asella (2400m above sea level (a.s.l.)), Adama (1600m a.s.l.), and Semara (400m a.s.l.). Volunteers from the local general population were asked to complete a brief questionnaire and have vital signs measured. Individuals reporting acute or chronic illness were excluded. RESULTS: A positive qSOFA score (i.e. ≥2), indicating severe illness in patients with infection, was common among the studied population (n = 612). The proportion of participants with a positive qSOFA score was significantly higher in Asella (28.1%; 55/196), compared with Adama, (8.3%; 19/230; p<0.001) and Semara (15.1%; 28/186; p = 0.005). Concerning the parameters comprised in qSOFA, the thresholds for RR (≥22/min) were reached in 60.7%, 34.8%, and 38.2%, and for BPsys (≤100 mmHg) in 48.5%, 27.8%, and 36.0% in participants from Asella, Adama, and Semara, respectively. DISCUSSION: The high positivity rate of qSOFA score in the studied population without signs of acute infection may be explained by variations of the physiological range of different vital signs, possibly related to the altitude of residence. Adaptation of existing scores using local standard values could be helpful for reliable risk assessment.

Blood culture result profile and antimicrobial resistance pattern: a report from neonatal intensive care unit (NICU), Asella teaching and referral hospital, Asella, south East Ethiopia.

Background: Antimicrobial resistance is one of the major public health emergencies worldwide, and this trend didn't spare developing countries like Ethiopia. The objective of this study was to evaluate patterns of bacterial isolates and local antimicrobial susceptibility patterns in neonatal sepsis. Methods: A hospital based observational study was conducted from April 2016 to May 2017 in Asella teaching and referral hospital (ATRH). A total of 303 neonates with clinical sepsis were included. Collected data were entered into EPI-INFO version 3.5.1 for cleanup; and then exported to SPSS version 21 for further analysis. Frequencies and proportion were used to describe the study population in relation to relevant variables. Results: Bacterial growth was detected in 88 (29.4%) of blood cultures. Predominantly isolated bacteria were coagulase negative staphylococci (CoNS) 22 (25%), Escherichia coli (E.Coli) 18 (20.5%) and Staphylococcus aureus 16 (18%). Resistance rates of S. aureus and CoNS against Ampicillin were 11 (69%) and 20 (91%) respectively. The resistance rate of E. coli against Ampicillin and Gentamycin were 12 (66.7%) and 10 (55.6%) while Klebsiella spp. resistance rate gets much higher against these two first line antibiotics [10 (91%) and 9 (82%) respectively]. Similarly, both Gram-positive and Gram-negative bacteria isolates were also highly resistant to third generation Cephalosporins, and 63 (72%) isolated bacteria showed multidrug-resistance. However; Gram-positive bacteria isolates had better susceptibility patterns to third line antibiotics like Clindamycin, Vancomycin and Ciprofloxacin while Gram-negative isolates had a higher susceptibility to Ciprofloxacin and Amikacin. Conclusion: CoNS, S. aureus, E. coli and Klebsiella spp. were the leading bacterial causes of neonatal sepsis in our study. They were highly resistant to first- and second-line empiric antimicrobial treatment used at NICU (Neonatal intensive care unit), reducing the antimicrobial choices for management of neonatal sepsis. Fortunately, the mentioned isolated bacteria remained susceptible to third line antibiotics used to treat neonatal sepsis.
