After exposure of the sheep parietal pleura to 240 mOsm/kg (hyposmolar) the transmesothelial resistance (R

) significantly increased (p < 0.05) while at 340 mOsm/kg (hyperosmolar) the R

was not significantly altered.

PEs osmolality differs depending on the underlying pathology and is linked to PE pH and glucose. Hypo-osmotic PEs can lead to decreased pleural permeability. These results warrant further study of the PEs osmolality levels on the function of the pleural mesothelial cells.

We reviewed a spectrum of congenital heart defects assessed in our center between 1/2010 and 4/2020, evaluated their gross anatomy, assessed the age distribution, evaluated performed surgical procedures, and correlated gross and ultrasound findings.

All necroptic cases and explanted hearts that underwent specialized cardiac autopsy were included in this study. Autopsy findings including gross description of congenital heart defects together with echocardiographic findings were retrospectively assessed. In surgically corrected hearts, the operation records were included as well. All congenital heart defects and surgical procedures were subclassified into main and additional category.

The study included 92 necroptic cases of live-born children, 7 stillbirths, 2 cases of young adults, 50 induced abortions, and 5 explanted hearts, with median age 36 weeks. The most frequently encountered leading congenital heart defects were hypoplastic left heart syndrome, aortic stenosis, septal defects, or persistent artcongenital heart defects were usually complex, often surgically corrected or evaluated as a result of induced abortion or still birth. Cardiac autopsy therefore places high demands on pathologists with regards to proper gross heart assessment. It is also an invaluable part of quality control in prenatal cardiology.

Trigeminal neuralgia features jolts of pain along the distribution of the trigeminal nerve. If patients fail conservative management, microvascular decompression (MVD) is typically the next step in treatment. MVD consists of implanting a separating material, often Teflon, between the nerve and compressive lesions. A review found similar success and complication rates between Teflon and Ivalon, another commonly used material. The aim of this study was to analyze outcomes and complications associated with Teflon and Ivalon in MVD.

We conducted a 2-center retrospective cohort study of trigeminal neuralgia treated with MVD between 2005 and 2019. Patients with no postoperative follow-up were excluded. Postoperative pain was graded using the Barrow Neurological Institute (BNI) pain intensity score. Relapse was defined as a BNI score of 4-5 during follow-up after initial pain improvement or an initial BNI score of 1-3.

The study included 221 MVD procedures in 219 patients. Ivalon was implanted in 121 procedures, and Teflon was implanted in 100 procedures. Multivariate analysis found that implant type had no effect on final BNI score (P= 0.305). Relapse rates were similar at 5- and 10-year follow-up (5-year Ivalon 10.7%, Teflon 18.0%, P= 0.112; 10-year Ivalon 11.6%, Teflon 19.0%, P= 0.123). There was no difference in postoperative immediate facial numbness (P= 0.125). Postoperative hearing difficulty was higher in the Ivalon cohort (8.4% vs. 1.0%; P= 0.016).

We found no significant difference in final BNI score or risk of relapse between Ivalon and Teflon. Complications were similar, although Ivalon was more associated with temporary postoperative hearing loss.

Foramen magnum decompression (FMD) is the first-choice treatment for Chiari malformation (CM). However, it has been suggested that cerebellar herniation and syringomyelia occur as a natural protective event to prevent neural damage caused by atlantoaxial instability. It is argued that treating instability is the main treatment. Positive results of atlantoaxial fusion have been reported in the literature, but there are no studies including the results of atlantoaxial fusion as the second treatment in patients in whom classical decompression failed. In our study, we report the results of these patients to help in the selection of treatment and we present our treatment algorithm for CM with syringomyelia.

Thirteen patients who had undergone FMD and duraplasty due to CM and syringomyelia in our clinics and who had recovered clinically and radiologically but had recurrent complaints during long-term follow-up were evaluated. C1-C2 distraction and fusion were performed. We evaluated these patients radiologically and clinically.

The mean age of the 13 patients was found to be 32.4 years. Male to female ratio was 67. The complaints recurred after an average of 2.1 years. Also, 3 cases were presented with their clinical characteristics and radiologic findings.

FMD may fail even with duraplasty, and treatment of CM in recurrent cases is still controversial. Recently, atlantoaxial instability has been reported to be the main pathology of CM, and the cure for pathology is to treat instability. Recurrent CMs with syringomyelia in which FMD has failed should be treated by atlantoaxial fixation.

The transcanal transpromontorial approach has been introduced to remove vestibular schwannomas. As with other techniques, preservation of the facial nerve (FN) is challenging. This pilot study described FN outcomes of patients preoperatively and postoperatively assessed with electromyography (EMG) and blink reflex (BR).

Between September 2017 and December 2018, 10 patients (5 men; 5 women; mean age, 59.8 years; age range, 25-77 years) underwent removal of vestibular schwannoma via the transcanal transpromontorial approach. find more FN assessment using EMG/BR and clinical evaluation with the House-Brackmann (HB) grading scale was performed preoperatively and 2 months postoperatively. If facial impairment was present postoperatively, further analysis was performed 6 months after surgery.

All 10 patients had normal FN function on preoperative EMG/BR. After 2 months, 4 patients had normal FN function on EMG/BR, 4 patients showed a slight delay of FN responses, 1 patient had moderate dysfunction, and 1 patient had consistent damage.
