Definitive diagnosis often depends on liver biopsy (percutaneous, transjugular, or open). Often presents as asymptomatic hepatomegaly and mild elevations in biochemical liver tests. Long-term: severe hepatic necrosis and fibrosis, portal hypertension, continued alcohol consumption. Liver transplantation may be an option in carefully selected pts who have been abstinent 6 months. Liver biopsy: stage 1- destruction of interlobular bile ducts, granulomas; stage 2- ductular proliferation; stage 3- fibrosis; stage 4- cirrhosis. Glucocorticoids, D-penicillamine, azathioprine, chlorambucil, cyclosporine of no value. Mortality correlates with severity of underlying liver disease (hepatic reserve). Table 158-2 Classification of Cirrhosis According to Child and Turcotte Class A B C Serum bilirubin, mol/L (mg/dL) Serum albumin, g/L (g/dL) Ascites Encephalopathy Nutrition Prognosis 34 (2) 35 (3. Control of Acute Bleeding Choice of approach depends on clinical setting and availability. Endoscopic band ligation or sclerotherapy- procedure of choice (not always suitable for gastric varices); band ligation is now preferred because of lower complication rate and possibly greater efficacy- application of bands around "pseudopolyp" of varix created by endoscopic suction; sclerotherapy involves direct injection of sclerosant into varix; 90% success rate in controlling acute bleeding; complications (less frequent with band ligation than sclerotherapy)- esophageal ulceration and stricture, fever, chest pain, mediastinitis, pleural effusions, aspiration. Due to risk of aspiration, endotracheal intubation should be performed prior to placing Blakemore-Sengstaken tube. Decreases but does not eliminate risk of recurrent bleeding; effect on overall survival uncertain but compares favorably to shunt surgery. Propranolol or nadolol- nonselective beta blockers that act as portal venous antihypertensives; most effective in well-compensated cirrhotics; generally given in doses that reduce heart rate by 25%. Portosystemic shunt surgery: portacaval (total decompression) or distal splenorenal (Warren) (selective; contraindicated in ascites; Alternative procedure- devascularization of lower esophagus and upper stomach (Sugiura). Ammonia may deplete brain of glutamate, an excitatory neurotransmitter, to form glutamine. Blood ammonia most readily measured marker, although may not always correlate with clinical status. Lactilol, a second-generation disaccharide that is less sweet than lactulose and can be dispensed as a powder, is not yet available in the United States. Flumazenil, a short-acting benzodiazepine receptor antagonist, may have a role in management of hepatic encephalopathy precipitated by benzodiazepine use. Associated disorders include anaphylaxis, allergic rhinitis, urticaria, asthma, and eczematous (atopic) dermatitis. Cross-linking of this IgE by antigen causes cellular activation with the subsequent release of preformed and newly synthesized mediators. The mediators have been implicated in many pathophysiologic events associated with immediate type hypersensitivity, such as vasodilatation, increased vasopermeability, smooth-muscle contraction, and chemotactic attraction of neutrophils and other inflammatory cells. Urticaria involves superficial dermis and presents as circumscribed wheals with raised serpiginous borders and blanched centers; wheals may coalesce. Vasculitic urticaria typically persists 72 h, whereas conventional urticaria often has a duration 48.

Bacterial transferase enzymes inactivate the drug by acetylation, phosphorylation, or adenylation. Meningitis (Haemophilus influenzae, Neisseria meningitidis, Streptococcus pneumoniae) and Rocky Mountain spotted fever (Rickettsia rickettsii). Limited use owing to toxicities but often still used in developing countries because of low cost. Treats anaerobic infections above the diaphragm vs metronidazole (anaerobic infections below diaphragm). Inhibit protein synthesis by binding to 50S subunit and preventing formation of the initiation complex. Bone marrow suppression (especially thrombocytopenia), peripheral neuropathy, serotonin syndrome. Contraindicated in pregnant women, nursing mothers, and children < 18 years old due to possible damage to cartilage. May cause tendonitis or tendon rupture in people > 60 years old and in patients taking prednisone. Gardnerella vaginalis, Anaerobes (Bacteroides, Treats anaerobic infection below the diaphragm C difficile).

Disulfiram-like reaction (severe flushing, tachycardia, hypotension) with alcohol; headache, metallic taste. Used for meningococcal prophylaxis and chemoprophylaxis in contacts of children with Haemophilus influenzae type B. Minor hepatotoxicity and drug interactions (cytochrome P-450); orange body fluids (nonhazardous side effect). Pyrazinamide is a prodrug that is converted to the active compound pyrazinoic acid. Multidrug-resistant P aeruginosa, multidrug-resistant Acinetobacter baumannii: polymyxins B and E (colistin).

Dermatophytoses (especially onychomycosis-fungal infection of finger or toe nails). Oral treatment of superficial infections; inhibits growth of dermatophytes (tinea, ringworm). Teratogenic, carcinogenic, confusion, headaches, disulfiram-like reaction, cytochrome P-450 and warfarin metabolism. Treatment of plasmodial species other than P falciparum (frequency of resistance in P falciparum is too high). Beginning therapy within 48 hours of symptom onset may shorten duration of illness. Obstructive crystalline nephropathy and acute renal failure if not adequately hydrated. Bone marrow suppression (leukopenia, neutropenia, thrombocytopenia), renal toxicity. Nephrotoxicity, electrolyte abnormalities (hypo- or hypercalcemia, hypo- or hyperphosphatemia, hypokalemia, hypomagnesemia) can lead to seizures. Disinfection and sterilization Autoclave Alcohols Chlorhexidine Hydrogen peroxide Iodine and iodophors Goals include the reduction of pathogenic organism counts to safe levels (disinfection) and the inactivation of self-propagating biological entities (sterilization).
Natural sources of curare are Strychnos toxifera symptoms quitting weed order genuine lariam online, Chondrodendron tomentosum and related plants medicine daughter lyrics cheap lariam 250 mg without prescription. Search has continued for neuromuscular blockers to provide greater cardiovascular stability during surgery and for drugs with differing onset and duration of action to suit specific requirements symptoms xanax addiction buy lariam 250 mg on-line. The latest additions are doxacurium symptoms rsv purchase generic lariam canada, pipecuronium, rocuronium, mivacurium, rapacuronium and cisatracurium. Intermediate acting: Vecuronium, Atracurium, Cisatracurium, Rocuronium, Rapacuronium 3. Soaking a portion of the sciatic nerve in curare solution did not affect the twitches and a curarized muscle still responded to direct stimulation-thus, nervous conduction and muscle contraction were intact. Note the thick, bulky molecule of competitive blocker d-tubocurarine and slender, flexible molecules of depolarizing blockers decamethonium and succinylcholine muscle fails to contract in response to nerve impulse. At very high concentrations, curare like drugs enter the Na+ channels and directly block them to produce more intense noncompetitive neuromuscular block that is only partly reversed by neostigmine. In other words a zone of inexcitability is created round the end plate preventing activation of the muscle fibre. Because in the focally innervated mammalian muscle, stimulation is transient; longer lasting depolarization of muscle end plate produces repetitive excitation of the fibre. These drugs do not dissociate rapidly from the receptor induce prolonged partial depolarization of the region around muscle end plate Na+ channels get inactivated (because transmembrane 342 Drugs Acting on Peripheral (Somatic) Nervous System Table 25. The rate of attainment of peak effect and the duration for which it is maintained depends on the drug (Table 25. Clinical monitoring of neuromuscular block In anaesthetic practice neuromuscular block (especially during recovery) is monitored by recording contractile responses of thumb muscles to transcutaneous ulnar nerve stimulation. Four supramaximal electrical stimuli are applied at 2Hz and contractions of thumb muscle are recorded. Autonomic ganglia Because the cholinergic receptors in autonomic ganglia are nicotinic Chapter 25 Skeletal Muscle Relaxants 343 are practically devoid of it. Histamine releasing potential of other neuromuscular blockers is graded in Table 25. With repeated administration redistribution sites are filled up and duration of action is prolonged. The unique feature of atracurium is inactivation in plasma by spontaneous nonenzymatic degradation (Hofmann elimination) in addition to that by cholinesterases. Consequently its duration of action is not altered in patients with hepatic/renal insufficiency or hypodynamic circulation. It is the preferred muscle relaxant for such patients as well as for neonates and the elderly. Cisatracurium this R-Cis, R-Cis enantiomer of atracurium is nearly 4 times more potent, slower in onset, but similar in duration of action. Because of longer duration of action, frequently needing reversal, its use is now restricted to prolonged operations, especially neurosurgery. Doxacurium A bisquaternary muscle relaxant having the least rapid onset and the longest action: suitable for long duration surgeries. It exerts little cardiovascular action, though transient hypotension and bradycardia can occur. Vecuronium A close congener of pancuronium with a shorter duration of action due to rapid distribution and metabolism. Recovery is generally spontaneous not needing neostigmine reversal unless repeated doses have been given. Cardiovascular stability is still better due to lack of histamine releasing and ganglionic action; tachycardia sometimes occurs. The same drug also serves as maintenance muscle relaxant, seldom needing reversal.
Reviewing associated biochemistry medicine plus lariam 250 mg generic, physiology alternative medicine buy generic lariam 250mg line, and microbiology can be useful while studying pharmacology medications errors purchase lariam 250mg with visa. Mencken Pharmacology "Nobody has ever measured treatment diabetes discount 250 mg lariam, not even poets, how much the heart can hold. Primary heart tube loops to establish left-right polarity; begins in week 4 of gestation. Defect in left-right dynein (involved in L/R asymmetry) can lead to dextrocardia, as seen in Kartagener syndrome (primary ciliary dyskinesia). Patent foramen ovale-caused by failure of septum primum and septum secundum to fuse after birth; most are left untreated. Developing septum secundum Septum primum Foramen primum Foramen secundum Septum primum Foramen ovale (closed) Degenerating septum primum Foramen secundum Septum primum Septation of the chambers Atria Septum primum grows toward endocardial cushions, narrowing foramen primum. Aorticopulmonary septum rotates and fuses with muscular ventricular septum to form membranous interventricular septum, closing interventricular foramen. Growth of endocardial cushions separates atria from ventricles and contributes to both atrial septation and membranous portion of the interventricular septum. Conotruncal abnormalities associated with failure of neural crest cells to migrate: Transposition of great vessels. Valvular anomalies may be stenotic, regurgitant, atretic (eg, tricuspid atresia), or displaced (eg, Ebstein anomaly). At birth, infant takes a breath; resistance in pulmonary vasculature left atrial pressure vs right atrial pressure; foramen ovale closes (now called fossa ovalis); in O2 (from respiration) and in prostaglandins (from placental separation) closure of ductus arteriosus. Fetal-postnatal derivatives AllaNtois urachus MediaN umbilical ligament Ligamentum arteriosum Ligamentum venosum Fossa ovalis Nucleus pulposus MediaL umbilical ligaments Ligamentum teres hepatis (round ligament) Contained in falciform ligament. Pericardium consists of 3 layers (from outer to inner): Fibrous pericardium Parietal layer of serous pericardium Visceral layer of serous pericardium Pericardial cavity lies between parietal and visceral layers. E S1 I A2 P2 Normal delay Wide splitting E S1 I A2 P2 Abnormal delay Fixed splitting = E S1 I A2 = P2 Paradoxical splitting Heard in conditions that delay aortic valve closure (eg, aortic stenosis, left bundle branch block). Normal order of valve closure is reversed so that P2 sound occurs before delayed A2 sound. Therefore on inspiration, P2 closes later and moves closer to A2, thereby "paradoxically" eliminating the split (usually heard in expiration). Diastolic heart sounds include the murmurs of aortic/pulmonic regurgitation, mitral/tricuspid stenosis. Most commonly due to agerelated calcification in older patients (> 60 years old) or in younger patients with early-onset calcification of bicuspid aortic valve. Long diastolic murmur, hyperdynamic pulse, and head bobbing when severe and chronic. Often due to aortic root dilation, bicuspid aortic valve, endocarditis, rheumatic fever. Phase 2 = plateau-Ca2+ influx through voltage-gated Ca2+ channels balances K+ efflux. Ca2+ influx triggers Ca2+ release from sarcoplasmic reticulum and myocyte contraction. Phase 3 = rapid repolarization-massive K+ efflux due to opening of voltage-gated slow K+ channels and closure of voltage-gated Ca2+ channels. In contrast to skeletal muscle: Cardiac muscle action potential has a plateau, which is due to Ca2+ influx and K+ efflux. Key differences from the ventricular action potential include: Phase 0 = upstroke-opening of voltage-gated Ca2+ channels. Fast voltage-gated Na+ channels are permanently inactivated because of the less negative resting potential of these cells. Phase 3 = inactivation of the Ca2+ channels and activation of K+ channels K+ efflux. Includes: Romano-Ward syndrome-autosomal dominant, pure cardiac phenotype (no deafness). Wolff-Parkinson-White syndrome Most common type of ventricular preexcitation syndrome. Treatment includes anticoagulation, rate control, rhythm control, and/or cardioversion.
