PY is a specific and potentially fatal infection, which is common in our country and must be differentiated from IM. A high index of suspicion and early institution of specific antibiotics followed by operation is therapeutic.

To describe the newly designed technique of applying topical oxygen therapy for large wounds. C arm sterile disposable cover is used for covering the wound. For abdominal and pelvis wounds, two artificial holes are created at one end of the cover for the inclusion of the limb. Free end of the cover is secured with adhesive, and a hole is created for the insertion of the suction catheter. Oxygen cylinder is connected to the suction catheter, and oxygen is supplied at the rate of 10 L/min. Three patients were treated with topical oxygen therapy. These patients were cases of necrotizing soft tissue infections and large post traumatic wounds. There were less requirements of debridement and granulation tissue appeared earlier. The cost of one cycle of the therapy is less than 500 INR. Topical oxygen therapy is the recent modality for improved wound healing. The novel method of applying topical oxygen devised by us is effective, feasible, and cost-effective as compared to standard devices.

Background: Spinal intramedullary cysts present a radiological dilemma. We present a rare case of a conus intramedullary arachnoid cyst and report on its differentiating features and management. Case Description: We report a case of a 30-month-old child who presented with decreased gluteal sensation and urinary dribbling for 6 months. Apart from some slowness in walking, the power was normal in all four limbs. Imaging showed a non-enhancing, T2-weighted hyperintense 12 × 8 mm conus intramedullary cyst without any edema. A T12-L1 laminotomy followed by marsupialization of the cyst was done. Histopathology was suggestive of an arachnoid cyst. The postoperative course was uneventful with improvement in muscle strength and achievement of regular milestones. We also present the pertinent review of the literature to date. Conclusion: Intramedullary arachnoid cysts are a rare entity and should form the differential diagnosis for cysts presenting in the conus medullaris. Simple decompressive options may suffice for symptomatic cases and radical excision may be avoided. A high index of suspicion is essential considering the subtle nature of presenting symptoms.
