The impact factor (IF) or journal impact factor (JIF) of an academic journal is a sciento-metric index calculated that reflects the yearly mean number of citations of articles published in the last two years in a given journal. It is calculated as: IFᵧ = Citationsᵧ/[Publicationsᵧ₋₁ + Publicationsᵧ₋₂] For example, in 2017, there were 74090 citations of 2015 and 2016 Nature…

Dermatomes : Mnemonic
Note: C1 doesn’t have a sensory branch For the purpose of making learning easier, we divide the remaining dermatomal segments into 4 groups which will be accompanied by analogies and mnemonics. C2-C4 These supply the “hooded cape” region. C2: hood region abutting the trigeminal distribution C3: upper neck C4: lower…

Nerve Conduction Study (NCS) and Electromyography (EMG) : Mnemonic Approach
Nerve Conduction Study (NCS) In the Nerve conduction study, assessment must be done for ABCDEFGH. Action potential Amplitude Measures the height of response in millivolts (mV) for motor nerve and microvolts (μV) for sensory nerve Indicates quantity of axons contributing to action potential Block of conduction CMAP on proximal stimulation…

Handtevy Method : Emergency Drug Dose by Age
To obtain the correct weight for each age, assign each finger a chronological odd number starting with 1, representing the age in years. Now, using the same fingers, count in the multiples of 5, starting with 10 to obtain the corresponding ideal body weight in kilograms. For the even ages,…

Boutonniere and Swan neck Deformity – Pathophysiology
Understanding of the Boutonniere and Swan neck deformity requires clear concept of the finger extensor apparatus, which has been discussed here. The extrinsic extensor tendons trifurcate giving a central slip which attaches to the middle phalanx base and two lateral slips which join with lateral band (formed by intrinsic muscles…
