Cervical transpedicular screw fixation is safe and is probably going to be the gold standard for cervical spine fixation. However, cervical transpedicular screw use in the Asian population can be limited as the transverse diameter in this group of patients may not be adequate to accommodate the 3.5-mm pedicular screw thus injuring the vital structures located in the close proximity of the pedicles. Thus lateral mass fixation remains the mainstay of treatment. The present study evaluated the transverse cervical pedicle diameter of C2-C7 vertebrae in a pilot study in 27 Indian subjects using computed tomography (CT) imaging and evaluated the feasibility of transpedicular screw fixation in them. ⋯ We found that the transverse pedicle diameter of cervical pedicles in the Indian subjects is smaller compared to the Western population. Although transpedicular screw fixation has stronger pullout strength compared to lateral mass fixation, its use must be considered carefully and individually. Preoperative CT evaluation is a must before transpedicular fixation in the cervical spine, especially in the Indian female population. As an option 2.7-mm screws can be devised for the Indian population giving a wider safety margin.

Case Reports
Swiss cheese ventricular septal defect with myocarditis - a rare coexistence in a neonate.
Myocarditis is defined as acute inflammation of the myocardium, usually following a non-specific flu-like illness, and encompasses a wide range of clinical presentations ranging from mild or subclinical disease to heart failure. We report a 12-day-old healthy full-term neonate who presented with abrupt onset of congestive cardiac failure (CCF) following a viral prodrome. Examination revealed persistent sinus tachycardia, lymphocytosis, gross cardiomegaly, nonspecific electrocardiogram changes with echocardiography showing Swiss cheese ventricular septal defect (VSD). ⋯ This is the first case report showing coexistence of VSD with myocarditis in a neonate presenting as early-onset acute cardiac failure. The report highlights the importance of screening for myocarditis in all previously normal babies presenting primarily with cardiogenic symptoms even if a structural heart disease is coexistent early in life. A simplified algorithm for work-up of CCF in a neonate is proposed.
