Pneumorrhachis Following Neck Penetrating Injury: A Case Report.

The development of air in the spinal canal is an uncommon and usually asymptomatic event. Also known as pneumorrhachis (PNR), the main information about this phenomenon is based on a few case reports published previously. It is highly difficult to identify this entity clinically, and in most publications, PNR was incidentally identified during image procedures, mainly computed tomography (CT) scans. With the advancement of technology and the development of guidelines for the treatment of penetrating and neck injuries, the number of PNR diagnosis has increased. It is also a common agreement among the articles reviewed that the least common cause of PNR is traumatic events. This report presents a rare case of pneumorrhachis as a consequence of a penetrating neck injury. The studied patient was a 27-year-old female with multiple stab wounds on the left posterior side of the neck and left shoulder, thereby developing left-side body weakness as a consequence of the wound. The patient was immediately evaluated and managed by the emergency team, and as the patient was vitally stable, she was shifted to an urgent CT scan. CT scan showed subarachnoid air focus, multiple extradural air foci, and spinal cord injury on the cervical spine. This patient was treated conservatively, but her neurological symptoms persisted until discharge.

A Single Institution Retrospective Comparison Study of Locoregional Recurrence After Accelerated Partial Breast Irradiation Using External Beam Fractionation Compared with Whole Breast Irradiation with 8 Years of Follow-Up.

BACKGROUND: Accelerated partial breast irradiation (APBI) was developed to address disadvantages of overall treatment time and potentially unnecessary radiation associated with whole breast irradiation (WBI). We report updated results of our single institution study using an external beam APBI regimen with a median follow-up of 8 years. METHODS: A total of 290 APBI patients with AJCC Stage 0-II breast cancer were compared with 290 WBI patients with matched tumor characteristics. Toxicities were scored based on the Common Terminology Criteria for Adverse Events (CTCAE v3.0). Cox regression models were used to predict likelihood of freedom from ipsilateral failure. RESULTS: Median follow-up was 8 years in the APBI group and 7.5 years in the WBI group. In the APBI group, there were 18 (6.2%) ipsilateral breast tumor recurrence (IBTR), 13 (72%) had elsewhere failures (EF), and 5 (28%) had local failures (LF) with a median time to failure of 64.1 months. In the WBI group, there were three (1.0%) IBTR; one (33%) was an EF and two (67%) were LF with a median time to failure of 91 months. APBI was 4.6 times more likely (hazard ratio 4.57, 95% confidence interval 1.3-16.2, p = 0.02) to have an IBTR than WBI after adjusting for age, tumor size, histology, grade, and estrogen receptor status. Fatigue, erythema, and desquamation toxicities were significantly less in the APBI group then the WBI group. CONCLUSIONS: IBTR rates were higher in external beam APBI group compared with WBI, but APBI had fewer toxicities. Clinicians must weigh the risks and benefits of APBI when making a recommendation for partial breast irradiation after lumpectomy.

Market Structure, Financial Dependence and Industrial Growth: Evidence from the Banking Industry in Emerging Asian Economies.

In this study, we examine the role of market structure for growth in financially dependent industries from 10 emerging Asian economies over the period of 1995-2011. Our approach departs from existing studies in that we apply four alternative measures of market structure based on structural and non-structural approaches and compare their outcomes. Results indicate that higher bank concentration may slow down the growth of financially dependent industries. Bank competition on the other hand, allows financially dependent industries to grow faster. These findings are consistent across a number of sensitivity checks such as alternative measures of financial dependence, institutional factors (including property rights, quality of accounting standards and bank ownership), and endogeneity consideration. In sum, our study suggests that financially dependent industries grow more in more competitive/less concentrated banking systems. Therefore, regulatory authorities need to be careful while pursuing a consolidation policy for banking sector in emerging Asian economies.
