A rare case of an incarcerated incisional hernia with gravid uterus.

Herniation of a gravid uterus through an abdominal wall incisional hernia with overlying skin necrosis is exceptionally rare. A 29-year-old multiparous K30 + 4/40 pregnant female presented with a 1-month history of worsening abdominal wall skin changes. Magnetic resonance imaging of the abdomen and pelvis confirmed herniation of the gravid uterus into the hernia sac. A lower uterine segment caesarean section and hernia repair were performed by the general surgical and obstetrics team in view of the potential maternofoetal complications. This case highlights the importance of early recognition and the difficulties in managing gravid uterus herniation.

Routine Postoperative Imaging Is Not Indicated in the Management of Mandibular Fractures.

PURPOSE: Prior literature has shown that routine postoperative computed tomography (CT) scans for mandibular fractures have no effect on outcomes and complications; however, past surveys have reported that most clinicians continue to order routine scans. We aimed to determine the current use of routine postoperative CT scans, evaluate what factors contribute to this practice, and identify differences in outcomes and complications among patients with either routine, indicated, or no postoperative CT scans. PATIENTS AND METHODS: We conducted a retrospective review of consecutive patients treated for a mandibular fracture at Vancouver General Hospital from January 1, 2007, to March 1, 2012. RESULTS: We included 167 patients in the study for analysis. No significant differences in outcomes or complications were found between patients who had an indicated postoperative CT scan (27%) and patients with no scans (64%). Only the treating surgeon had a statistically significant effect on whether a patient received a postoperative CT scan (P < .001), and those patients who had an indicated postoperative CT scan (9%) were more likely to have a decreased level of temporomandibular joint function (P = .002) and increased incidence of complications and secondary operations (P < .001 and P < .001, respectively). CONCLUSIONS: Routine postoperative CT scans were found to have no significant effect on outcomes and complications, and a clinician's individual practice was the most significant factor for whether a patient received a routine postoperative CT scan. Future work should aim at providing well-defined indications for postoperative imaging.

Reduced ipsilesional cortical volumes in fetal periventricular venous infarction.

BACKGROUND AND PURPOSE: Perinatal stroke causes most term-born hemiplegic cerebral palsy. Many suffer additional sequelae. Periventricular venous infarction (PVI) is a common fetal stroke in which isolated subcortical injury may cause only motor deficits. However, cognitive, language, and behavioral deficits also occur. We hypothesized that ipsilesional cortical gray matter volumes are reduced in PVI. METHODS: Children (12 months to 18 years) with MRI-confirmed PVI were identified through the Alberta Perinatal Stroke Project. We developed an MRI method to quantify sectional gray (GM) and white matter (WM) volumes from lesioned and unlesioned (control) hemispheres (OsiriX software). Differences in cortical GM and WM volumes were compared between hemispheres in preselected regions "above" the lesion (middle) and anterior and posterior to this. Outcomes dichotomized for "cortical dysfunction" (cognitive, behavioral, language) and motor deficit severity (Pediatric Stroke Outcome Measure) were compared with GM volumes. RESULTS: Twenty-two children (81% boys; median age, 8 years) were included. Methods demonstrated high intrarater and inter-rater reliabilities (ρ=0.988, ρ=0.943) and minimal observer bias. Ipsilesional GM volume was significantly reduced in the middle (P=0.007) and posterior (P=0.03) regions. Middle ipsilesional WM volumes were reduced (P<0.001). The degree of GM reduction was not associated with cortical dysfunction or severity of motor deficit. CONCLUSIONS: Ipsilesional GM volume is diminished in PVI. Speculative mechanisms include retrograde neuronal degeneration and disrupted migration. Neuropsychological testing of larger samples is required to determine clinical significance.
