Abstract Background: Catheter related sheath (CRS) formation secondary to chronic indwelling central venous catheters (CVC) is a well-documented complication. When these fibrin sheaths calcify, they can form a “cast” surrounding the catheter. Upon removal of the CVC a rare complication can occur where the calcified sheath remains in-situ leaving behind an intraluminal catheter-shaped cast. Case Presentation: We present the case of a 57-year-old dialysis dependent woman found to have a right internal jugular vein cast during the evaluation and treatment of methicillin resistant staphylococcus aureus (MRSA) bacteremia. Conclusions: This case reviews and discusses the embolic complications suspected to be a result of this cast. Our case provides insight into the clinical course, diagnostic methods, and imaging identification of a rare pathology and its unique complications.

Introduction. Thoracic empyema is an infrequent complication of appendicitis that has rarely been reported in the literature. Case Presentation and Review of the Literature. The case of a 11-year-old boy who was admitted for medical management of an appendicular mass is presented. His clinical course was complicated by the development of an appendicular abscess and an extensive right-sided empyema. A comprehensive review of the literature was conducted including the most representative cases. The data were collected and analyzed by two independent investigators. Ten cases were found. Most patients were young individuals (mean age: 25.1 years; male : female ratio: 0.5). Risk factors for thoracic empyema included pregnancy (10%) and age (60%). The most frequent organisms isolated were Escherichia coli, Bacteroides spp., and Klebsiella spp. The survival rate was 100%. Conclusion. Thoracic empyema should be considered a potential cause of respiratory distress in patients with appendicitis. Furthermore, the abdomen should be carefully evaluated as a source of infection in patients with thoracic empyema without an underlying lung disease.

Abstract Background: Antiphospholipid syndrome (APS) is associated with artery or venous thrombosis. However, non-thrombus venous stenosis is rarely reported.Case presentation: This study described two young women with APS-related internal jugular vein stenosis (IJVS) and reviewed current literatures on this issue, including clinical features, diagnosis and treatment.Conclusions: IJVS is a rather rare complication of APS. This is first report of non-thrombus venous stenosis resulted from aPL mediated vessel wall damage. High titer of aPL could induce stenosis without thrombosis formation due to long-term standardized anticoagulation. Follow-up of autoantibodies are necessary to be done dynamically. Treatment for patients with IJVS of autoimmune etiology should be concomitant use of anticoagulants and steroids.

BACKGROUND: Intravascular fractured fragment of double lumen catheter with embolisation is a serious and rare complication. Another serious complication includes infection, thrombosis, arrhythmias, and pulmonary embolism. We report a successful surgical venous cut-down technique in the retrieval of an intravascular fractured fragment of tunnelled double lumen catheter in a hemodialysis patient. CASE REPORT: A 51-year-old female underwent hemodialysis through a tunnelled double lumen catheter and had her arterio-venous graft matured. During retrieval of tunnelled double lumen catheter procedure, the distal part of the catheter was fractured and slipped into the internal jugular vein. Chest radiograph revealed intravascular double lumen catheter extending from the distal part of the right internal jugular vein to right atrium. The procedure of foreign body retrieval was done the next day under general anaesthesia and C-Arm guidance using right internal jugular venous cut-down approach. A right-angle clamp was used to retrieve the fragment without any post-procedure complications. CONCLUSION: Intravascular fractured fragment of double lumen catheter is a dangerous situation as are all the intravascular foreign bodies. The choices of the technique for retrieval of the fractured fragment are varied. It depends on the type and site of a fractured fragment as well as the surgeon experiences.

Abstract Background: Laser in situ keratomileusis (LASIK) is increasingly used worldwide to correct a wide range of refractive errors. Toxic anterior segment syndrome (TASS), a noninfectious inflammatory disease with symptoms and signs that resemble bacterial infection, is a rare complication of LASIK. Case presentation: We report a case of TASS in a 42-year-old male patient after LASIK surgery in both eyes for hyperopia. Diagnosed clinically. Discussion and conclusion: Little information about complications after LASIK is available. TASS is a general term used to describe acute, sterile postoperative anterior segment reactions. Patients with TASS will often experience blurry vision with or without pain within 12 to 48 hours after surgery. Steroids have shown to be effective in resolving the inflammatory response, reducing the pain and recovering the vision.

Abstract Background: To report a case of femtosecond laser-assisted in situ keratomileusis (FS-LASIK) following small incision lenticule extraction (SMILE) lenticule in situ implantation to treat a rare complication. Case presentation: The hyperopic left eye of a 46-year-old patient with refraction of +7.75 diopters sphere (DS)/-1.25 diopters cylinder (DC)×5°and corrected distance visual acuity (CDVA) of 20/50 mistakenly underwent SMILE procedure for myopic astigmatism (-8.50DS/-1.50DC×175°) due to medical record error. The extracted lenticule was subsequently re-implanted in situ. After 8 months, the left eye underwent FS-LASIK to correct hyperopia and astigmatism （+5.0DS/-0.75DC×100°. Two years after FS-LASIK, corneal tomography showed no ectasia and microscopy revealed transparent cornea. The left eye obtained CDVA of 20/50 and the refraction was -0.75DS/-0.25DC×165°. Conclusion: SMILE lenticule in situ implantation offers a solution for rare complications and correction of refractive error following lenticule re-implantation with FS-LASIK is feasible and effective.

Background: More than 90% of the global 400 000 annual malaria deaths occur in Africa. The current SARS-CoV-2 pandemic has resulted in more than 830 000 deaths in its first 10 months. Case presentation: This case describes a patient who had travelled from Mozambique to Cape Town, presented with a mild febrile illness, and was diagnosed with both COVID-19 and uncomplicated Plasmodium falciparum malaria infection. She responded well to malaria treatment and had an uneventful COVID-19 admission. Her blood smear showed a low malaria parasitaemia and a relatively high gametocyte load. Conclusion: We postulate that her clinical course and abnormal smear could well be due to reciprocal disease-modifying effects of the infections. The presenting symptoms of COVID-19 may mimic endemic infectious diseases including malaria, tuberculosis, pneumocystis pneumonia and influenza thus there is a need for clinical vigilance to identify and treat such co-infections.

The design code Eurocode 7 relies on semi-probabilistic calculation procedures, through utilization of the soil parameters obtained by in situ and laboratory tests, or by the means of transformation models. To reach a prescribed safety margin, the inherent soil parameter variability is accounted for through the application of partial factors to either soil parameters directly or to the resistance. However, considering several sources of geotechnical uncertainty, including the inherent soil variability, measurement error and transformation uncertainty, full probabilistic analyses should be implemented to directly consider the site-specific variability. This paper presents the procedure of developing fragility curves for levee slope stability and piping as failure mechanisms that lead to larger breaches, where a direct influence of the flood event intensity on the probability of failure is calculated. A range of fragility curve sets is presented, considering the variability of levee material properties and varying durations of the flood event, thus providing crucial insight into the vulnerability of the levee exposed to rising water levels. The procedure is applied to the River Drava levee, a site which has shown a continuous trend of increased water levels in recent years.

Insight Into

Methicillin-resistant Staphylococcus aureus (MRSA) infection is detrimental to hospitalized patients. With diminishing choices of antibiotics and the worry about resistance to colistin in synergistic combined therapy, there are suggestions for the use of herbal derivatives. This investigation evaluated the synergistic effects of Nigella sativa (NS) in combination with beta-lactam (β-lactam) antibiotics on extreme drug-resistant (XDR) MRSA isolates. NS concentrations of 10, 7.5, 5.0, 2.5, 1.0, and 0.1 µg/mL, alone and in combination with β-lactam antibiotics, were used to determine the antimicrobial susceptibility of MRSA isolates by the well diffusion method. Time–kill assays were performed using a spectrophotometer, with time–kill curves plotted and synergism ascertained by the fractional inhibitory concentration (FIC). Scanning and transmission electron microscopy were used to gain insight into the mechanism of action of treated groups. Isolates were inhibited by the NS concentrations, with differences in the zones of inhibition being statistically insignificant at p < 0.05. There were statistically significant differences in the time–kill assay for the MRSA isolates. In addition, NS combined with augmentin showed better killing than oxacillin and cefuroxime. The mechanism of action shown by the SEM and TEM results revealed cell wall disruption, which probably created interference that led to bacterial lysis.
