Mnemonic: Our City Is Kept Safe And Sound From Malice Remember the enzymes of the cycle: All the enzymes are in the matrix of mitochondria except succinate dehydrogenase which is in inner mitochondrial membrane. Pyruvate from aerobic glycolysis enters mitochondria, where it may be converted into acetyl-CoA (irreversible reaction) under…

Medial Medullary (Dejerine’s) Syndrome : Anatomical basis mnemonic
As already discussed in the previous section about Lateral Medullary (Wallenberg) Syndrome: 6 “S” pass/lie on the Side (latetral) of Medulla Except the anteromedian part supplied by vertebral artery, rest of the medulla is supplied by PICA Let us now review the relevant anatomy and physiology of the medial portion…

Anatomical basis of Wallenberg (Lateral Medullary) Syndrome : Mnemonic
Before proceeding into the disease itself, let’s review – relevant anatomy of the medulla with a simple mnemonic. The Side (lateral) part of Medulla contains 6 “S“ 1. Spinocerebellar tract Posterior spinocerebellar tract: Ascends and enters to ipsilateral cerebellum via ipsilateral inferior cerebellar peduncle Anterior spinocerebellar tract: Ascends and enters…

Clonus : Clinical Examination and Mechanism
Definition of clonus Clonus is a rhythmic sustained involuntary muscular contraction (generally 5-8 Hz) evoked by sudden passive stretch of the muscle and tendon. Eliciting Clonus Clonus is commonly elicited in gastrocnemius (ankle clonus). Other sites where clonus can be elicited are quadriceps (patellar clonus), finger flexors and jaw. 1….

Approach to Low Back Pain
Definition of Low Back Pain Low back pain (LBP) is defined as pain, muscle tension or stiffness localized below the costal margin and above the inferior gluteal folds, with or without leg pain (sciatica). “Diagnostic triage” after excluding non-spinal causes of low back pain classifies LBP into 3 broad categories:…

Radiation cystitis : Diagnosis, prevention and management
Cause of radiation cystitis: Bladder in the radiation field (treatment of pelvic malignancies like prostate, cervical, colorectal) Epidemiology of radiation cystitis: Incidence: 23% to 80% (variability due to variability in type and dosing of radiotherapy among different medical subspecialities) Incidence of severe hematuria: 5-8% Mean duration for developing radiation cystitis:…
