    Etiology o E.coli & Bacteroides fragilis

    Clinical Manifestations o Abdominal pain cramping, severe, steady at the lower epigastric, within 4-6hrs localizes at RLQ (may vary from different

    locations of pain of the appendix) o Anorexia o Vomiting

    Signs: o Direct and Indirect tenderness o Rovsing's signpain in the RLQ when palpatory pressure is exerted in the LLQ (indicates site of peritoneal irritation) o Psoas sign have patient lay on the left side as the examiner slowly extends the right thigh, thus stretching the iliopsoas

    muscle (indicates an irritative focus proximal to that muscle) o Obturator sign passive internal rotation of the flexed right thigh with the patient supine

    Laboratory Findings: o CBC mild leukocytsis, 10,000-18,000 cells/mm3 (acute uncomplicated AP) o Urinalysis to rule out UTI

    ACUTE CHOLECYSTITIS

    Clinical Manifestations: o RUQ or epigastric pain that may radiate to the right upper part of the back or the

    interscapular area o It is usually more severe than the pain associated with uncomplicated biliary colic o Fever, anorexia, nausea, vomiting are present; patient is reluctant to move, as the

    inflammatory process affects the parietal peritoneum. o On PE: focal tenderness and guarding at the RUQ; a mass, the gallbladder and adherent

    omentum, is occasionally palpable; however, guarding may prevent this. o Murphy's sign, an inspiratory arrest with deep palpation in the right subcostal area, is

    characteristic of acute cholecystitis.

    Laboratory Findings: o mild to moderate leukocytosis (12,000 to 15,000 cells/mm

    3); but some patients may have a normal WBC

    o high WBC (>20,000) is suggestive of a complicated form of cholecystitis such as gangrenous cholecystitis, perforation, or associated cholangitis

    o Serum liver chemistries are usually normal, but a mild elevation of serum bilirubin, < 4 mg/mL, may be present along with mild elevation of alkaline phosphatase, transaminases, and amylase.

    o Severe jaundice is suggestive of common bile duct stones or obstruction of the bile ducts by severe pericholecystic inflammation secondary to impaction of a stone in the infundibulum of the gallbladder that mechanically obstructs the bile duct (Mirizzi's syndrome).

    Differential Diagnosis: o peptic ulcer with or without perforation, pancreatitis, appendicitis, hepatitis, pleuritis

    CHRONIC CHOLECYSTITIS (Biliary Colic)

    Clinical Manifestations: o Recurrent attacks of pain, episodic o Pain is constant and increases in severity over the first half hour or so, typically lasts 1-5 hours. It is located in the

    epigastrium or right upper quadrant and frequently radiates to the right upper back or between the scapula o Pain is occurs typically during the night or after a fatty meal o Often associated with nausea and vomiting o On PE: RUQ tenderness during an episode of pain

    Laboratory Findings: o WBC count and liver function tests are usually normal in uncomplicated gallstones o Ultrasound standard diagnostic test for gallstones o CT scans show extrahepatic biliary tree status and adjacent structures o Endoscopic retrograde cholangiography (ERCP) and Endoscopic ultrasound rarely needed for uncomplicated gallstones

    but for the stones in the common bile duct, in particular when associated with obstructive jaundice, cholangitis or gallstone pancreatitis.

    Management: o For symptomatic gallstones, elective laparoscopic cholecystectomy is the procedure of choice. o Diabetic patients with symptomatic gallstones should undergo cholecystectomy promptly as they are prone to develop

    acute cholecystitis o In pregnant women, elective laparoscopic cholecystectomy is allowed during the 2

    nd trimester

    CCHHOOLLEEDDOOCCHHOOLLIITTHHIIAASSIISS SSUURRGGEERRYY

    - Common bile duct stones - RUQ tenderness, nausea, vomiting - Symptoms such as pain and jaundice may be intermittent

    Imaging Studies: o Magnatic Resonance Cholangiography (MRC) provides excellent anatomic detail and has a sensitivity and specificity of 95

    and 89%, respectively o Ultrasonography o Endoscopic cholangiography is the gold standard for diagnosing common bile duct stones

    Management: o Endoscopic cholangiogram o Sphincterotomy and ductal clearance of stones followed by laparoscopic cholecystectomy

    - May precipitate various physical exercise, emotional stress or a medical or surgical illness - Chest pain deep and visceral, heavy, squeezing and crushing - Similar to discomfort of angina pectoris, occurs at rest but more severe, lasts longer - Accompanied by weakness, sweating, nausea and vomiting, anxiety and a sense of impending doom, pallor, substernal chest pain of

    more >30 minutes - Pericardial friction rub is usually heard

    Laboratory Findings: o ECG ST elevation, Q wave

    Transmural MI is present if the ECG demonstrates Q wave and loss of K waves Nontransmural MI is considered if ECG shows only transient ST segment and T wave changes

    o Serum Cardiac Biomarkers Cardiac-specific troponin-T and troponin-I are biochemical markers which usually rise in patients with STEMI not

    seen in healthy individuals. o MB isoenzymes of CK more specific but not diagnostic of a myocardial rather than a skeletal muscle source of CKMB o Non-specific reaction to myocardial injury is associated with PMN leukocytosis, WBC often reaches 12,00-15,00; ESR rises

    more slowly than WBC o 2D-Echo cardiac imaging provides abnormalities of wall motion o High-resolution MRI contrast agent (gadolinium) is administered, and images are obtained after a 10-minute delay; a

    bright contrast appears in areas of infarction

    Differential Diagnosis: o Acute Pericarditis

    Chest discomfort radiating from trapezius is not seen in STEMI o Pulmonary Embolism

    STEMI may present with sudden onset of breathlessness that may progress to pulmonary edema and embolism

    Initial Management: o Pre-hospital Care

    Patient may manifest arrhythmias or mechanical complications (pump failure) May cause sudden ventricular fibrillation

    o Management in Emergency Department Aspirin in suspected STEMI causes inhibitin of cyclooxygenase I followed by reduction of thromboxane A2 If there is hypoxemia, O2 administration with nasal cannula or face mask at 2-4L/min

    o Control of Chest Discomfort Nitroglycerine (sublingual) up to 3 doses of 0.4mg at about 5mins interval should be administered, or IV

    nitroglycerine if with ongoing ST segment ischemia shifts. IV -blockers diminishes O2 demand

    Hospital Phase Management: o Activity ambulation should be encouraged if without complication o Diet diet rich in potassium, magnesium and fiber but not sodium o Bowel use of stool softener o Sedation diazepam or lorazepam (adverse effect: delirium)

    Pharmacotherapy: o Antithrombotic Agents its role is to maintain patency of infarct related artery and reduce thrombosis that can lead to

    embolization Clopidogrel reduces risk of clinical events, reinfarction, stroke and death Heparin + Aspirin may help about 6 liver per 1000 patients

    o Beta-adrenergic blocker improves the myocardium O2 demand, reduces pain, reduces infarct site, reduces arrhythmias o Inhibition of RAAS reduces mortality rate; reduction in ventricular remodeling with subsequent reduction in the risk of

    CHF, indolent to ACE inhibitors

    - Pathophysiologic Hallmark: reduction in airway diameter - Hypoxia - universal finding during acute exacerbations

    Classic Symptom Triad: (1) Wheezing, (2) Dyspnea, (3) Cough

    Typical Acute Attack: o Often occurs at night o With occupational asthma, attacks may occur at work or after work o Patients experience a sense of constriction in the chest, often with a nonproductive cough o Respiration becomes audibly harsh o Wheezing is first noted during expiration and then with inspiration as well o Expiration becomes prolonged o Mucus plugging and impending suffocation o Accessory muscles become visibly active, and a paradoxical pulse often develops o The end of an episode is frequently marked by a cough that produces thick, stringy mucus

    4 Major Classification of Asthma Severity by Clinical Features o Mild, intermittent

    - Symptoms occur 2 or fewer times per week. - Asymptomatic between attacks - Exacerbations are brief (hours to at most days) and of varying intensity. - Nocturnal symptoms are rare, less than twice a month. - The FEV1 is >80% predicted during episodes.

    o Mild, persistent - Symptoms occur more than 2 times a week but less than once a day. - Exacerbations may affect normal activity. - Nocturnal symptoms occur more than twice a month. - FEV1 is >80% predicted during episodes.

    o Moderate, persistent - Symptoms occur daily. - Exacerbations occur more than twice a week and may last days. - Exacerbations affect normal activity. - Nocturnal symptoms occur more than twice a month. - FEV1 is between 60% and 80% during episodes.

    o Severe, persistent - Symptoms are continual. - Physical activity is limited. - Exacerbations are frequent. - Nocturnal symptoms are frequent. - FEV1 is always abnormal and < 60% predicted during episodes.

    Differential Diagnosis: 1. Chronic Bronchitis 2. Foreign Body Aspiration 3. Chemical Pneumonias 4. Acute Left Ventricular Failure

    Diagnosis: o Reversibility 15% in FEV1 after 2 puffs of B-adrenergic agonist o Positive wheal and flare reactions to skin tests o Sputum and blood eosinophilia o Chest radiograph

    Management: o Eliminate allergen first, avoid trigger factors o Oxygen at 2-6 lpm via nasal cannula o Nebulization

    - Salbutamol neb/inhaler q3-6hours (1 neb/2-4 puffs), or - Ipatropium bromide + Salbutamol (Combivent)
