Ponticulus Posticus: An Important Diagnostic Finding Often Missed in Lateral Cephalograms.

Aim: The purpose of the current study was to investigate the presence of the ponticulus posticus (PP) frequently encountered in lateral cephalograms.

Materials And Methods: About 500 patients of age 12-40 years were selected whose digital lateral cephalogram was recorded and traced to confirm the presence of the PP and categorize as: (A) Absent, as evidenced by lateral cephalograms. (B) Complete PP evidenced by the presence of circumferential bone bridge that connected the upper articular process to the atlas's posterior arch.

Surface contamination by SARS-CoV2 RNA in dedicated COVID care area of a tertiary care hospital in North India.

Environmental surfaces are potential source of SARS-CoV2 transmission. The study assessed the efficacy of hospital disinfection policy and contamination of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) RNA in COVID management Hospital. Inanimate surfaces from both patient areas (n = 70) and non-patient areas (n = 39) were sampled through surface swabbing and subjected to Reverse transcriptase PCR.
