 The rapid guide includes three diagnosis recommendations and four management recommendations covering patients with suspected or confirmed COVID-19 with different levels of disease severity, throughout the care pathway from outpatient facility or hospital entry, to home discharge.  The rapid guide offers considerations about implementation, monitoring and evaluation, and identifies research needs.  The guide will be relevant for clinicians, hospital managers and planners, policy-makers, hospital architects, biomedical engineers, medical physicists, logistics staff, and control officers involved in water/sanitation and infection prevention.

Surgical resection is the best option for prolonged survival in patients with primary or secondary liver tumors. A sufficient future liver remnant (FLR) volume is needed to prevent post-hepatectomy liver failure (PHLF). With the aim of increasing FLR, a new two-step technique has been recently developed. Our aim is to report our initial experience with associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique. Analysis was conducted of ten patients previously considered locally unresectable because of small FLR. During first surgical step liver parenchymal partition and portal vein ligation was performed. Seven days after the first procedure, once volumetric and functional studies have demonstrated an appropriate FLR volume, the resection of the deportalized hemiliver was achieved. This technique was successfully performed in all ten patients (feasibility 100 %). Six were male with mean age of 55.2 years (range 39-77). Mean preoperative FLR volume and FLR/total liver volume were 408.4 ml and 27.8 %. Mean postoperative FLR volume was 733 ml representing a mean volume increase of 325 ml or 82 % (range 31-140) (p < 0.0001). All resections were R0 (4 right hepatectomies, 5 right trisectionectomies and 1 left trisectionectomy). There were two grade A post-hepatectomy liver failures. Morbidity was 40 % and mortality 0 %. With a mean follow-up of 187 days, disease-free survival and overall survival were 80 and 100 %, respectively. ALPPS induces a great and fast FLR hypertrophy allowing R0 resections in patients otherwise considered unresectable because of small FLR volume, without severe PHLF and low mortality in experience centers. Further experience is needed to determine long-term outcomes.

Objective: To describe the contribution of 3-dimensional computed tomography (3D-CT) in the prenatal diagnosis of skeletal dysplasias (SD) in a cohort of patients with inconclusive diagnosis by ultrasound (US). Methods: Between May 2007 and February 2010, six pregnant women with suspected fetal SD on US examination but with no specific diagnosis were studied with 3D-CT. The images were evaluated by a multidisciplinary team who proposed a likely diagnosis. Further postnatal workup included clinical and radiological evaluation in all cases. Prenatal and postnatal diagnoses were compared. Results: The use of 3D-CT provided a precise diagnosis confirmed postnatally in 5/6 patients. These included osteogenesis imperfecta type II (n = 2), osteogenesis imperfecta type III (n = 1), chondrodysplasia punctata (n = 1) and thanatophoric dysplasia type I (n = 1). A precise diagnosis could not be made in 1 case – either pre- or postnatally. Conclusion: Prenatal 3D-CT contributed to the diagnosis of the specific fetal SD in the majority of these cases. 3D-CT may have a complementary role to US where fetal SD is suspected, but no specific diagnosis can be made using US alone. Further studies on clinical performance and risk-benefit analysis are needed.

Our results showed that there is a significant reduction in the reading time using the colon dissection visualization technique without detriment to the detection rate, that is, competitive to conventional virtual colonoscopy interpretation results.
