Trends in Pediatric Mild Traumatic Brain Injury During COVID-19-Related Lockdown-A Single-Center Study.

BACKGROUND: A relevant number of visits to pediatric emergency departments (pED) are associated with mild traumatic brain injury (mTBI). On March 16, 2020, the Bavarian government declared a first full lockdown (LD) related to the coronavirus (COVID-19) pandemic. AIM: The aim of the study was to investigate the impact of LD on pediatric mTBI. METHODS: Retrospective chart review of presentations to a pED due to mTBI. Study periods covered LD (03/17/2020 through 05/05/2020) and the same time in 2017, 2018, and 2019 as reference period (RP). Comparative analyses were performed by Chi-square or Fisher's exact test. RESULTS: Numbers of mTBI cases decreased by half. Age distribution did not differ. A significantly higher proportion of mTBI were related to falls at home (p = 0.001). Further, a higher rate of hospital admissions (p = 0.03), a higher proportion of intensive care unit admissions (p = 0.001), a longer duration of hospital stay (p = 0.02), and a higher rate of intracranial pathologies on neuroimaging were observed during LD (p = 0.007). CONCLUSION: The decrease in mTBI presentations is likely due to an absolute decrease in numbers related to the LD measures, combined with a hesitation to present very minor mTBI to the hospital, because of fear of being infected or not to put additional strain on the healthcare system during this healthcare crisis. On the other hand, data of those that presented with mTBI tend to reflect the more severe spectrum of mTBI.

Use of Barbed Sutures for Congenital Diaphragmatic Hernia Repair.

BACKGROUND: Congenital diaphragmatic hernia (CDH) repair can be challenging, particularly when a larger defect is present. Barbed sutures prevent the suture from slipping back after approximation of the tissues. Although introduced almost 2 decades ago, barbed sutures have not been widely used for CDH repair. We report our initial experience and pitfalls. METHODS: All patients presenting with CDH from 2021 onward underwent repair using barbed sutures. Demographics, operative parameters, complications, and outcomes were prospectively recorded. RESULTS: A total of 13 patients underwent CDH repair during the study interval (median age 6 days, range 3 days to 5.75 years). Median operative time was 89 min (range 46 to 288 min). Five thoracoscopic and eight open procedures were performed. Severe pulmonary hypertension and ECMO (extracorporeal membrane oxygenation) were considered contraindications for thoracoscopic repair. The included patients were compared to a historic controlled group performed without barbed sutures. The barbed suture facilitated easy and quick closure of the defects in most cases and obviated the need for knot tying. One patient in the thoracoscopic group had a patch placed due to high tension after the barbed sutures tore the diaphragm. At a median follow-up time of 15 months (range 2 to 34 months), one patient had died, and one patient with complete diaphragmatic agenesis was home-ventilated. There were no recurrences. Median operative time trended lower (89 min) than in the historic control group repaired without barbed sutures (119 min, p < 0.06) after eliminating outliers with large, complex patch repairs. CONCLUSIONS: Barbed sutures simplify congenital diaphragmatic hernia repair regardless of whether a minimal-invasive or open approach is performed. Patch repair is not a contraindication for using barbed sutures. The resulting potential time savings make them particularly useful in patients with cardiac or other severe co-morbidities in which shorter operative times are essential. In cases with high tension, though, the barbs may tear through and produce a "saw" effect on the tissue with subsequent damage.

The diagnostics and treatment of pediatric urology patients in the clinical routine can be extremely challenging. In comparison to adult patients, congenital diseases, more time consuming examinations and limited options in addition to the parents' expectations must be taken into account in the diagnostic work up. In this first of two parts we will delve into ultrasound diagnostics as the cornerstone in the diagnostic pathway of children with hydronephrosis ans take a closer look on contrast enhanced ultrasound (CEUS). Conventional voiding cystourethrography still plays a major role in the diagnostic pathway of vesicoureteric reflux and will be treated in this article. Computed tomography should only be considered in pediatric patients in rare cases, always taking radiation into critical account. Magnetic resonance imaging provides an excellent anatomical overview without exposing the child to unnecessary radiation. This article provides an overview on the diagnostic imaging studies in pediatric urology and brings tips for the diagnostic evaluation.

The diagnostics and treatment of pediatric urology patients in the clinical routine can be extremely challenging. In contrast to adult patients, the main concerns in the diagnostics of congenital diseases are time consuming examinations and limited options in addition to the expectations of the parents. The exact knowledge of the diagnostic possibilities in association with the correct interpretation of the indications is essential. Simple processes can be much more time consuming because of a lack of compliance, especially in very young children. Sonography is considered the standard for imaging in pediatric urology. Profound knowledge of the embryonal development and also physiological processes throughout childhood contribute to making the correct diagnosis. This article deals with the possibilities of nuclear medicine diagnostics, advanced diagnostics in bladder voiding disorders and finally imaging diagnostics in the pediatric urological operating room.

Alien limb phenomenon following posterior cerebral artery stroke: a distinct clinical entity.

Alien limb syndrome following stroke within the territory of the posterior cerebral artery is exceedingly rare. A right-handed female experienced left homonymous hemianopia, visuospatial neglect, and proprioceptive loss of her left hemi-body. She experienced unintended, involuntary movements of her left arm and hand, which interfered with and disturbed motor actions of daily life performed with her right upper limb. There was no denial of ownership, but she interpreted movements of her left upper limb to be annoying, out of her will and unwanted. The alien limb phenomenon improved in parallel with improvement of proprioceptive loss over a 12-week of in-patient rehabilitation. A recently proposed theoretical concept of the alien limb phenomenon after posterior artery stroke is discussed.
