Aneurysmal dilatation of the aortic sinuses of Valsalva has been most extensively documented in the setting of aortopathies, particularly Marfan syndrome. On the other hand, there is limited data in the literature about congenital sinus of Valsalva aneurysms outside this context. For the purpose of this review, we carried out a literature search on aneurysmal dilatation of the sinuses of Valsalva in Marfan syndrome, and compared this with congenital sinus of Valsalva aneurysms, also including data from a case series from our institution. In conclusion, there are differences in management of aortic dilatation in Marfan syndrome and congenital sinus of Valsalva aneurysms. Though less well-recognised, congenital aneurysms are often associated with significant morbidity and mortality and timely intervention is necessary.

Bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation (HSCT) is a major cause of morbidity and mortality with limited treatment options. Lung transplantation (LTX) has been rarely reported as a treatment option for selected HSCT recipients with this problem. In the present study, we reported six patients who underwent LTX due to BOS after HSCT (two females, four males) from January 2012 to December 2014 in our center. The median time from HSCT to diagnosis of BOS was 2.5 years (ranging from 1 to 5 years). At a median time of 4 years (ranging from 2 to 5 years) after diagnosis of BOS, four patients received bilateral sequential LTX, and two patients received single LTX. One of the recipients suffered from mild acute rejection after LTX, another suffered from primary lung graft dysfunction on post-operation day 2, and three experienced fungal infections. The median time for follow-up after LTX was 19.5 months (ranging from 12 to 39 months). At present, all patients are alive with good functional capacity and no relapse of BOS and hematologic malignancy conditions. Patients who received bilateral LTX have better pulmonary functions than patients who received single LTX.

Compared with conventional injection molding, injection-compression molding can mold optical parts with higher precision and lower flow residual stress. However, the melt flow process in a closed cavity becomes more complex because of the moving cavity boundary during compression and the nonlinear problems caused by non-Newtonian polymer melt. In this study, a 3D simulation method was developed for injection-compression molding. In this method, arbitrary Lagrangian-Eulerian was introduced to model the moving-boundary flow problem in the compression stage. The non-Newtonian characteristics and compressibility of the polymer melt were considered. The melt flow and pressure distribution in the cavity were investigated by using the proposed simulation method and compared with those of injection molding. Results reveal that the fountain flow effect becomes significant when the cavity thickness increases during compression. The back flow also plays an important role in the flow pattern and redistribution of cavity pressure. The discrepancy in pressures at different points along the flow path is complicated rather than monotonically decreased in injection molding.

Nephrotic syndrome (NS) is one of the most common glomerular diseases with signs of nephrosis, heavy proteinuria, hypoalbuminemia, and edema. Dysfunction of glomerular filtration barrier causes protein loss through the kidneys. Focal segmental glomerulosclerosis (FSGS) accounts for nearly 20% of NS among children and adults. Adult-onset FSGS/NS is often associated with low response to steroid treatment and immunosuppressive medication and poor renal survival. Several genes involved in NS and FSGS have been identified by linkage analysis and next-generation sequencing. Most of these genes encode proteins and are highly expressed in glomerular podocytes, which play crucial roles in slit-diaphragm signaling, regulation of actin cytoskeleton dynamics and maintenance of podocyte integrity, and cell–matrix interactions. In this review, we focus on the recently identified genes in the adult-onset NS and FSGS and discuss clinical significance of screening of these genes.

Cushing’s syndrome (CS) during pregnancy is a rare condition with significant maternal and fetal complications. A case of CS during the third trimester of pregnancy secondary to adrenocortical adenoma was reported. Literature review revealed the disadvantages of different treatments in this period. Besides the conservative treatment, surgery is recommended for CS during the third trimester of pregnancy secondary to adrenal adenoma, if an experienced surgeon is available.

Familial amyloid cardiomyopathy is a challenging condition that mimics many other diseases, particularly in patients with pronounced neurological presentations and unexplained or equivocal cardiac abnormalities. In this case, a 57-year-old man was admitted for outpatient cardiological evaluation of progressive right heart failure and limb paraesthesias. The patient presented with hypertension, chronic Guillain-Barre syndrome, and sick sinus syndrome. Transthoracic echocardiograms showed a thickened ventricular wall and enlarged atrium. Tissue Doppler showed a restrictive filling pattern. Transthyretin (TTR)-associated amyloidosis, which was revealed by abdominal fat-pad biopsy and DNA analysis, explained the concurrence of independent pathological features, including neuropathy and cardiac involvement. Genetic testing identified a G>T mutation in exon 4 of the transthyretin (TTR) gene. This mutation resulted in the alanine-to-serine substitution at amino acid position 117. Moreover, genetic testing confirmed that the patient’s asymptomatic son carried the same amyloidogenic TTR mutation. Given these findings, the diagnosis of familial amyloid cardiomyopathy, which was misdiagnosed as chronic Guillain-Barre syndrome, was proposed.

Middle East respiratory syndrome coronavirus: current situation and travel-associated concerns

The emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 brought back memories of the occurrence of severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002. More than 1500 MERS-CoV cases were recorded in 42 months with a case fatality rate (CFR) of 40%. Meanwhile, 8000 cases of SARS-CoV were confirmed in six months with a CFR of 10%. The clinical presentation of MERS-CoV ranges from mild and non-specific presentation to progressive and severe pneumonia. No predictive signs or symptoms exist to differentiate MERS-CoV from community-acquired pneumonia in hospitalized patients. An apparent heterogeneity was observed in transmission. Most MERS-CoV cases were secondary to large outbreaks in healthcare settings. These cases were secondary to community-acquired cases, which may also cause family outbreaks. Travel-associated MERS infection remains low. However, the virus exhibited a clear tendency to cause large outbreaks outside the Arabian Peninsula as exemplified by the outbreak in the Republic of Korea. In this review, we summarize the current knowledge about MERS-CoV and highlight travel-related issues.
