Massive congenital arteriovenous malformation of the pterygomaxillary space.

A case is presented of a massive congenital, extracranial arteriovenous malformation (AVM). The origins and hemodynamic considerations that led to prior treatment failure are discussed. A sudden accelerated growth in the AVM, caused by an alteration in the hemodynamics of the feeding and draining vessels, mandated further surgical management. The treatment of choice is complete surgical excision at the time of diagnosis, if possible. Ligation of the feeding vessels alone is unsatisfactory and, like other adjunctive treatments, may lead to disastrous complications.

The correlation between craniovertebral angle, backpack weights, and disability due to neck pain in adolescents.

PURPOSES: To investigate the responses of the craniovertebral (CV) angle to backpack loadings in adolescents with and without neck pain and to explore the relationships between CV angle, relative backpack weight, neck pain and disability. METHODS: A cross-sectional single-blinded study was conducted on 60 adolescents (30 neck pain and 30 non-neck pain) aged from 13 to 18 years old. The verbal analog scale (VAS) and Chinese version of Northwick Park Neck Pain Questionnaire (NPQ) were used to assess neck pain severity and disability respectively. CV angle was measured in neutral and with backpack loadings of 5% to 30% of subject's body weight by using the Head Posture Spinal Curvature Instrument (HPSCI). RESULTS: In both groups, CV angles gradually decreased with increment of backpack loadings and the amount of decreases became significant from 10% body weight onwards (P < 0.05). Although the changes of CV angles did not show any significant differences at any point of comparison between the groups, the neck pain group showed a clinically significant decrease of CV angle (∼ 5°) at 10% relative loading whereas non-neck pain group did it at 15% relative loading. Change of CV angles did not show significant correlations with relative backpack weight, cervical pain and disability (P > 0.05). CONCLUSIONS: Our findings suggested a safety limit of 10% relative backpack load for adolescents. The results showed the tendency that the ability of maintaining good head posture in response to backpack loadings by non-neck pain subjects might be better than those with neck pain.

Although the changes of CV angles did not show any significant differences at any point of comparison between the groups, the neck pain group showed a clinically significant decrease of CV angle ( approximately 5 degrees ) at 10% relative loading whereas non-neck pain group did it at 15% relative loading. Change of CV angles did not show significant correlations with relative backpack weight, cervical pain and disability (P > 0.05). CONCLUSIONS: Our findings suggested a safety limit of 10% relative backpack load for adolescents.

Thrombophlebitis of the internal jugular vein secondary to pharyngitis.

A case of septic thrombophlebitis of the internal jugular vein after pharyngitis is reported. Because of the common use and effectiveness of antibiotics against throat infections, this complication is now rarely seen. This condition has characteristic signs and symptoms, and a diagnosis can be obtained when the physician is aware of these characteristics. Radionuclide scan and Doppler effect flow studies of the internal jugular vein are useful diagnostic adjuncts. If recognized early and treated promptly with antibiotics, resolution is the rule. The literature has been reviewed.
