Fetal tachycardia can be due to maternal fever in chorioamnionitis. Therefore chorioamnionitis is not indication of C-section. But fetal distress associated with deceleration is indication of C-section.
Both papillary muscle rupture and ventricular wall rupture can occur post-MI after 3-5 days but ventricle wall rupture has signs of hypotensive shock where as papillary muscle rupture has an MR murmur with less severe hemodynamic derangements.
Typical signs of Pericarditis : murmurs are absent in uremic pericarditis which is indication of dialysis

Systolic-Diastolic Bruit : RAS - (renal artery stenosis)
Systolic Bruit : AAA - Abdominal Aortic Aneurysm
Idiopathic intracranial HTN = aka = Benign intracranial HTN = Pseudotumor cerebri : Obese women , Besides OCP's the other '' non-idiopathic '' cause is Vitamin A overdose
Trigeminal Autonomic Cephalgias involve segments of V1 (headache, eye pain) are associated with autonomic syndrome ( horner's syndrome, lacrimation, rhinorrhea) Intracranial imaging required
Trigeminal neuralgias involve segments of V2, V3 (lancinating pain to the jaw, and lower half of face ) have NO autonomic syndrome No intracranial imaging required Rx : Carbamazepine
Trigeminal Cephalgias : the Cluster headache
Trigeminal Neuralgias : The Tic Douloureux
Primary Headaches : 1. Migraines 2. Cluster 3. Analgesic 4. Tension
Secondary Headaches : 1. SAH 2. Meningitis 3. Abscess 4. Tumor 5. Temporal Arteritis
Temporal arteritis : First Steroids to prevent irreversible blindness then get Biopsy
Triptan's : Contraindicated : in case of Coronary Artery Disease because it leads to vasoconstriction
Cluster heaches Rx : Oxygen important then Ergot or if Triptans fails can be prevented by Verapamil
Follow up : Vascular headaches such as Cluster and Migraine -- with Brain imaging
Pseudotumor cerebri : Dx by LP Rx : LP repeat - VP shunting (Important to stop OCP's if women age 20-30's taking OCP's -- then go for LP
Spinal Stenosis : present like Claudication but improves with leaning forward
AAA - big enough -- back pain do USG to fix it
Visceral organ pain -- Differential for back pain : case would be like someone get constipation or diarrhea (women with menstrual) without typical presentation of back pain
LP - improves - think NPH
Schizoaffective disorder : predominant mood symptoms with minimum duration of depressive / anxiety symptoms of 2 weeks with psychotic symptoms
Mid diastolic rumble at the apex -- MS and intracardiac tumor
Asystole/ PEA - do CPR - Atrial fibrillation when hemodynamically unstable then -- synchronized cardioversion
Ventricular fibrillation : Unsynchronized cardioversion
Palpable Bilateral Abdominal masses : ADPKD
Multifocal Atrial Tachycardia : COPD
Rotatory nystagmus : BPPV
BPPV ---- vs ----- Menier's disease :
BPPV : Otolith : Reproducible , recurrent vertigo , last less than 1 minute Dx : Dix halpike Rx : Epley maneuver
Menier's disease : Tinnitus , Fullness lasts less than 1 hour goes greater than 30 minute Rx : salt restriction and Diuretics , Meclizine
Labyrinthitis : Duration is in between of above problem its weeks with URI , hearing loss , tinnitus , Nausea , Vomiting without brain stem ( Central lesions) Rx : early Steroids and meclizine.
Peripheral vertigo : (BPPV, Menier's , Labyrinthitis) - Central vertigo : ( CVA, Post. Fossa tumor, Multiple sclerosis , Medications)
Coloric test : COWS : (Cold opposite warm same)
ALS : Rx : Riluzole
Rx : for Multiple sclerosis : Acute - Steroids , Chronic : IFN , Symptomatic Rx : if Urinary retention : Bethanecol if Urinary incontinence : Amitriptyline , If spasm : baclofen
Best test is EMG : 1. Mysthenia gravis 2. Eaton lambert syndrome 3. ALS
Must do CT scan in Mysthenia to check thymoma and in Eaton lambert to check Lung ca. i.e. Small cell carcinoma
Done LP : lots of protein and few cells suspect Guillain Barre syndrome
Raloxifene increases your risk of DVT less than Tamoxifene. The organizer is to Keep Raloxifene separate from Tamoxifene.
Ventricular free wall rupture : PEA associated
Ventricular aneurysm : akinesis of the ventricular wall on Echo
Pericarditis : EKG : PR segment depression
PSVT : narrowed complex - wide complex : hemodynamically unstable -- Rx : immediate cardioversion / Defibrillation
Cold water -- increases vagal tone like carotid massage --- decreases AV nodal conductivity
Stroke from Vertebral artery dissection -- Rx -- is heparin instead of alteplase
High Output cardiac failure : Paget disease , Beriberi , Pregnancy , Hyperthyroidism , Anemia
Remember LV free wall rupture presents like Cardiac tamponade
Inter-ventricular wall rupture : VSD : holosystolic murmur left sternal border as compared to papillary muscle rupture which is on apex
Inability to palpate to the point of maximal apical impulse is consistent with large pericardial effusion
Ursodeoxycholic acid DOC for PBC
Antibody and its Disease : ANA (lupus) , Anti-CCP (RA) , RF (RA) , Anti-Histone (Drug induced lupus) , Anti-dsDNA (Lupus and renal disease) , Anti-Centromere (Scleroderma - CREST) , Smooth muscle ( Autoimmune Hepatitis) , Ro + La (Sjogren's) Jo (Polymyositis) , Anti-mitochondrial (PBC) , Topoisomerase (Systemic Sclerosis)
