Introduction: Animal experimental evidence suggests that mechanisms of pain generation and response to treatment differ between neuropathic pain in the cephalic and the extracephalic innervation territories. Objectives: The objective of the study was to examine whether in humans an identical peripheral painful neuropathy is associated with different pain qualities and sensory abnormalities in the face as compared with the thoracic region. Methods: We retrospectively analysed epidemiological and clinical data of 639 patients with postherpetic neuralgia (PHN) in the face and at the trunk who were collected within a cross-sectional cohort survey and compared the respective sensory symptom profiles captured with the painDETECT questionnaire...

We describe a novel measurement of cranial morphology in pre- and post-operative scaphocephalic patients to complement the cephalic index. This will better describe restoration of normal skull and head shape, further defining the nuances of the corrected skull. In this retrospective comparative study the location of the euryon on the skull was statistically significantly different in preoperative scaphocephalic patients versus non-scaphocephalic controls. This difference was resolved with surgical cranial vault remodeling, indicating restoration of a normal skull profile...

OBJECTIVE In this study, the authors examined head shape through age 36 months for children with and without a history of positional plagiocephaly and/or brachycephaly (PPB). METHODS Infants with PPB (cases) were identified through a craniofacial clinic at the time of diagnosis. Infants without diagnosed PPB were identified through a participant registry. Clinician ratings of 3D cranial images were used to confirm the presence or absence of PPB. The cohort included 235 case infants (diagnosed PPB, confirmed with 3D imaging), 167 unaffected controls (no diagnosed PPB, no deformation detected), and 70 affected controls (no diagnosed PPB, discernible skull deformation)...

Background: Multidirectional cranial distraction osteogenesis (MCDO) is a procedure of ours developed earlier for treating craniosynostosis. However, the numerous bone flaps led to prolonged operative time and occasional bone detachment from dura. We have since simplified the osteotomy design. In treating sagittal synostosis, required bone flaps have been reduced to 11 (from ~20). Methods: In a 2-year period (2014-2015), 5 boys with sagittal synostosis underwent MCDO using our simplified and fixed-form osteotomy...

The purpose of this study was to analyze whether the anogenital distance (AGD) was associated with variability in semen parameters. Semen parameters analyzed following the WHO guidelines and sperm DNA fragmentation were evaluated in 160 semen samples obtained over a period of a year from 16 healthy male volunteers. Two types of AGD measurements from the anus to the rear base of the scrotum (AGDAS) and to the cephalic insertion of the penis (AGDAP) were taken in each individual. The association between AGDs and semen parameters were studied using three statistical tools: a) general coefficient of variation (CV) and intra-individual coefficient of variation (CVi), b) general linear models for repeated measures, and c) mixed model fixed effects panel data...

Arteriovenous fistulae (AVF) are the preferred choice of vascular access in hemodialysis patients; however, complications such as stenosis can lead to access failure or recirculation, which reduces dialysis efficiency. This study utilized computational fluid dynamics on a patient-specific radiocephalic fistula under hemodialysis treatment to determine the dynamics of access recirculation and identify the presence of disturbed flow. Metrics of transverse wall shear stress (transWSS) and oscillatory shear index (OSI) were used to characterize the disturbed flow acting on the blood vessel wall, while a power spectral density (PSD) analysis was used to calculate the any turbulence within the access...

PURPOSE: The effect of synostosis is not confined to the immediate vicinity of the suture. The authors hypothesized metopic craniosynostosis results in migration of lateral structures from midline, and differences in segmental volume of the cranial fossa. METHODS: A retrospective case-controlled cohort analysis of patients with nonsyndromic metopic craniosynostosis was performed. Craniometric angles, distances to landmarks from midline, cephalic index, and segmented volume ratios were calculated...

Background External cephalic version (ECV) is a maneuver that enables the rotation of the non-cephalic fetus to a cephalic presentation. The Newman-Peacock (NP) index, which was proposed by Newman et al. in a study published in 1993, was described as a prediction tool of the success of this procedure; it was validated in a North-American population, and three prognostic groups were identified. Purpose To evaluate the value of the NP score for the prediction of a successful ECV in a Portuguese obstetrical population, and to evaluate maternal and fetal safety...
