We report 25 cases of postpartum hemorrhage secondary to life-threatening severe uterine atony treated with this novel approach of using three vertical compression sutures. Success was achieved in 24/25 (96 %) of cases treated with three vertical sutures, without requiring hysterectomy except one.
To reduce maternal morbidity and mortality, three vertical compression sutures as a novel technique, can be attempted before applying other more complex interventions. It does not require any extra skill or training, and is an ideal option as its simplicity allows it to be performed by all obstetricians, including junior obstetric staff.

To evaluate whether sperm banking is under-used in adolescents with cancer.
We reviewed our 33 years long experience of semen cryopreservation and identified male subjects with cancer aged 14-21 years who banked their sperm. We hypothesized as a referring model a constant rate of referral in every age category (uniform distribution). In addition, we evaluated whether the distribution of the referrals per age varied according to historical periods and compared semen quality in the different age groups.
Overall, 317 subjects were selected. A sharp increase with age emerged (p < 0.001) the number of cases augmented from 4 at age 14 years to 79 at age 21 years. This significant increase persisted even when focussing only on subjects older than 16-18 years. An improvement of the distribution of cases per age group emerged when limiting the analysis to the last decade of activity; however, the increase remained significant (p < 0.001). Finally, we investigated whether semen quality differed according to age groups and failed to show marked differences, suggesting that sperm banking even at the youngest ages could be of potential benefit.
This study confirmed that sperm banking is under-used in adolescents with cancers. Future studies should better clarify the determinants of this low referral and identify interventions that can improve the situation.

They resemble spontaneous movements, but are exaggerated, repetitive and appear misplaced in a given communication context. Given that tics often go unnoticed, it has been suggested that they represent a surplus of action, or motor noise. In this conceptual position paper, we propose that tics and urges, but also patterns of the cognitive profile in Tourette syndrome might be explained by the principle of processing of neural noise and adaptation to it during information processing. We review evidence for this notion in the light of Tourette pathophysiology and outline why neurophysiological and imaging approaches are central to examine a possibly novel view on Tourette syndrome. GSK2245840 order We discuss how neurophysiological data at multiple levels of inspections, i.e., from local field potentials using intra-cranial recording to scalp-measured EEG data, in combination with imaging approaches, can be used to examine the neural noise account in Tourette syndrome. We outline what signal processing methods may be suitable for that. We argue that, as a starting point, the analysis of 1/f neural noise or scale-free activity may be suitable to investigate the role of neural noise and its adaptation during information processing in Tourette syndrome. We outline, how the neural noise perspective, if substantiated by further neurophysiological studies and re-analyses of existing data, may pave the way to novel interventions directly targeting neural noise levels and patterns in Tourette syndrome.
Aceruloplasminemia is an ultra-rare neurodegenerative disorder associated with massive brain iron deposits, of which the molecular composition is unknown. We aimed to quantitatively determine the molecular iron forms in the aceruloplasminemia brain, and to illustrate their influence on iron-sensitive MRI metrics.
The inhomogeneous transverse relaxation rate (R
*) and magnetic susceptibility obtained from 7T MRI were combined with Electron Paramagnetic Resonance (EPR) and Superconducting Quantum Interference Device (SQUID) magnetometry. The basal ganglia, thalamus, red nucleus, dentate nucleus, superior- and middle temporal gyrus and white matter of a post-mortem aceruloplasminemia brain were studied. MRI, EPR and SQUID results that had been previously obtained from the temporal cortex of healthy controls were included for comparison.
The brain iron pool in aceruloplasminemia detected in this study consisted of EPR-detectable Fe
ions, magnetic Fe

Among the saikosaponins, saikosaponin a (SSa), saikosaponin b1 (SSb1) and saikosaponin b2 (SSb2) are a group of isomers, which are difficult to separate by HPLC. In this study, a new method for separation and quantitation of saikosaponins was established by using ultra-high performance supercritical fluid chromatography (UHPSFC). A Torus Diol column (100 mm × 3 mm, 1.7 μm) was applied in this study. The mobile phase CO2 (A) was the main solvent with MeOH (B) as co-solvent. The results showed that the five saikosaponins were successfully separated within 22 min through optimization of chromatographic conditions. Besides, the UHPSFC method was applied for the quantitation of saikosaponins in a patent medicine Chaihu Dropping Pills, and demonstrated a good correlation coefficient (R2) ≥ 0.9990 in the range of 0.025 - 0.25 mg/mL. The recoveries of the five saikosaponins at three different concentrations were in the range of 90.GSK2245840 order
