These results suggest that frontal sinusotomy is not required to resolve frontal sinusitis associated with MSFB. As such frontal sinusitis appears to be a reactive process caused by fungal ball obstruction, it regresses spontaneously following fungus ball removal, drainage of the maxillary sinus, and middle meatal antrostomy.

To compare the effectiveness of chirp and tone burst stimuli in oVEMP and cVEMP testing for healthy adults METHODS This study was conducted in 56 healthy volunteers (112 ears). Ocular and cervical VEMP (oVEMP, cVEMP) tests were performed for each participant using tone burst and chirp stimuli. VEMP response rates, latency of each peak (p1-n1, n1-p1), peak to peak amplitude (p1-n1 amplitude and n1-p1 amplitude), and rectified amplitudes were measured and compared between these two different stimuli.

VEMP response rates with chirp stimuli are higher than the tone burst stimuli for both cVEMP and oVEMP tests (The difference was statistically significant for oVEMP, p = 0.001). Chirp stimuli have higher p1n1 amplitude and rectified amplitude and shorter p1and n1 latency then tone burst stimuli for cVEMP (p = 0.015, p = 0.007, p < 0.001, p < 0.001, respectively). Chirp stimuli also have higher n1p1 amplitude and shorter n1and p1 latency then tone burst stimuli for oVEMP (p = 0.006, p < 0.001, p < 0.001, respectively).

The present findings show that the chirp stimulus triggers earlier VEMP responses with higher amplitudes than the tone burst stimulus during cVEMP and oVEMP testing. VEMP response rate with chirp stimulus is also higher than the tone burst. Therefore chirp stimulus can be used in VEMP testing as effectively as, if not more than, tone burst stimulus in clinical practice.

The immunisation resulted in the induction of HEV-specific antibodies of high titre. The mAb G117-AA4 of IgG1 isotype was obtained showing a strong reactivity with the homologous E. coli, but also yeast-expressed capsid protein of HEV-3. The mAb strongly cross-reacted with ratHEV capsid protein derivatives produced in both expression systems and weaker with an E. coli-expressed batHEV capsid protein fragment. In addition, the mAb reacted with capsid protein derivatives of genotypes HEV-2 and HEV-4 and common vole hepatitis E virus (cvHEV), produced by the cell-free synthesis in Chinese hamster ovary (CHO) and Spodoptera frugiperda (Sf21) cell lysates. compound library inhibitor Western blot and line blot reactivity of the mAb with capsid protein derivatives of HEV-1 to HEV-4, cvHEV, ratHEV and batHEV suggested a linear epitope. Use of truncated derivatives of ratHEV capsid protein in ELISA, Western blot, and a Pepscan analysis allowed to map the epitope within a partially surface-exposed region with the amino acid sequence LYTSV. The mAb was also shown to bind to human patient-derived HEV-3 from infected cell culture and to hare HEV-3 and camel HEV-7 capsid proteins from transfected cells by immunofluorescence assay. The novel mAb may serve as a useful tool for further investigations on the pathogenesis of HEV infections and might be used for diagnostic purposes. KEY POINTS • The antibody showed cross-reactivity with capsid proteins of different hepeviruses. • The linear epitope of the antibody was mapped in a partially surface-exposed region. • The antibody detected native HEV-3 antigen in infected mammalian cells.

Parkes Weber syndrome (PWS) is a rare and congenital vascular malformation manifesting as hemihypertrophy of the extremities, cutaneous hemangiomas, varicose veins, and arteriovenous fistula of the affected limbs. The incidence rate of spinal arteriovenous fistula (AVF) associated with PWS is extremely rare.

We reported a case of an adolescent girl with PWS who presented with a rupture spinal perimedullary AVF at the level of T12-L1. She was successfully treated with emergent surgical decompression and subsequent endovascular embolization. The clinical features and treatment of spinal AVF associated with PWS were discussed and a brief literature review was presented.

Based on this case report, we suggested that the management of spinal AVF in PWS should also be individualized and be tailored according to the condition and expectation of the patients as well as the angioarchitecture of the vascular malformation.

In most cases, the etiology of the bleeding is multifactorial, and they can be either related to the mother or the fetus. Blunt prenatal trauma was occasionally associated with these hemorrhages, nevertheless, reports of hematomas secondary to mild traumas are rare. Within the prenatal intracranial bleedings, the most frequent are the subarachnoid hematoma and intraparenchymal, scarcely ever the epidural hematoma. Treating these bleedings is challenging due to the ongoing pregnancy. Thus, the prognosis is often reserved, with a mortality rate of 43% and 25% of neurological sequelae. Here, we report a singular case of a fetal epidural hematoma secondary to a mild blunt trauma at the third trimester with a good outcome.
