1 Ashti Doobay-Persaud M.D. Assistant Professor of Medicine September 19 th, 2013 Center for Global Health

2 Objectives Understanding your setting Practical Guidelines for Primary Care Reasoning without resources- Cases

3 Settings and Resources Country Urban vs. Rural Primary Care Clinic vs Hospital Available Labs and Diagnostic Testing What you definitely have: History and Physical Exam Skills Language Dependent

4 Top Diagnoses at Hillside Clinic and Mobiles

5 Primary Care Clinic Upper Respiratory Infections Asthma Skin Diseases Diarrhea Diabetes and Hypertension STIs Anemia

6 Available Resources in clinic Vital Signs, one O2 sat monitor Urine HCG Fingerstick Glucose No Chest XRAY machine Imaging and Referral Centers in the capital 3 hours and expensive transportation away Rxs available: amoxicillin, azithromycin, cefixime, CTX, dicloxacillin, TMP/SMX, metronidazole, topical anti-fungals, albendazole and permethrin

7 General Rules Keep it Simple (time, # of pills etc.) Consolidate Medications Do No Harm Quantity: Triage Quality Care- what we do here Pharmacokinetics Horse NOT Zebras Review: helminths, lice, scabies Only treat the patient you have seen

8 Case #1 3 yo presents with cough, congestion, fever, sore throat, headache, etc. Slightly tachypneic and tachycardic but well- appearing otherwise, rhinorrhea is present, clear lungs and playing well. Her 2 other siblings have had something similar. + developmental milestones What do you do next, what do you prescribe ? Is there anything else you would like to know on the HPI or PE ?

9 Case #1- RTC 3 days later Now she is febrile, tachypneic ( RR 45), tachycardic and has crackles and wheezing in one lung field and has a mild fever. She does not have visible retractions of her chest and can complete full sentences, she is still playful but less so compared to three days ago O2 sat: 98%/RA What do you do ? Should you have done something differently last time ?

10

11 Case # 2 In a rural village and a 78 yo F who cooks by the fire daily presents with wheezing, tachypnea and is unable to complete full sentences, her O2 sat is 80% on RA She is afebrile and has a chronic cough but no new fevers or cough She has gotten some inhalers in the past from Belize city What do you do ? Assume we have the same meds here as at home however not in clinic

13 What is this?

14

15 Scabies Sarcoptes scabiei Itchy papules and linear burrows occur in a symmetrical fashion, particularly in skin folds Head infestation uncommon, except in infants More itchy at nighttime Treatment- Permethrin 5% cream, treatment of clothing/bedding, treat family members

16 Rashes- Tropical Dermatidities Bacterial Viral Exanthem Viral Fungal Atopic

17 What is this rash?

18 Impetigo Superficial infection of epidermis, often at the site of skin damage Golden-yellow vesicle bursts, then crusts over Usually caused by staph aureus or streptococci Treatment- topical vs. PO antibiotic, soak off crusts

19

21

22 Tinea Infections Tinea pedis (athletes foot) Topical antifungals usually effective Tinea cruris (jock itch) Topical antifungals Tinea corporis (ring worm) Topical antifungals usually effective Tinea capitis Oral antifungals May progress to kerion (immune response to fungus)

23 4 days of non-bloody diarrhea. What are your follow-up questions ? What are you looking for on exam?

24 Warning Signs Fever Significant abdominal pain Blood or pus in stools > 6 stools per day Severe dehydration Ability to take po Elderly or very young Duration > 7 days

25 WHO Guidelines for Assessing Hydration Condition: Well, restless, lethargic, or unconscious Eyes: Normal or sunken Thrist: None, drinks eagerly, or unable Turgor: Goes back immediately or slowly

26 Diarrhea What are the causes of Non-Bloody Diarrhea ? Bloody Diarrhea ? Remember your setting

27 Diarrhea Non-Bloody: Preformed toxin: Food poisoning Viral: Rotavirus, norovirus Bacterial: E coli, cholera Parasites: Giardia, cryptosporidium

28 Diarrhea Bloody Bacterial: Campylobacter, Salmonella, Shigella, E coli Parasite: E. histolytica

29 Diarrhea Treatment If no warning signs & patient taking PO - supportive care If moderate dehydration - oral rehydration solution (ORS) Antibiotic treatment: For inflammatory diarrhea w/ warning signs or Giardia Cholera/Shigella

31 Reasoning without Resources Case 1: Ascites Case 2: Leg Edema

32 Case 1: Question 1 Frame Key features of the HPI Age Duration of symptoms Lack of pain, jaundice or constitutional sx + JVP, HJR WITHOUT edema No evidence of preceding exertional dyspnea

33 Case 1: Question 2 Physical Exam findings: General: barefoot, torn clothing Normal BP without pulsus, benign fundi No thrush Increased JVP and HJR Summation Gallup Holosystolic Kussmauls sign

34 Case 1 : Question 2 Ascites+RV failur e No RV Lift (not hyperdynamic) Clear Lungs, normal PMI, no MR murmur No edema next question What is the DDX of Ascites without edema ?

35 Case 1: Question 3 DDX Ascites without edema: Malignant Ascites TB Peritonitis Ascites due to RV Failure can have no edema in certain disease states

36 Case 1: Question 4 UA: proteinuria EKG: R atrial enlargement without RV or LV Hypertrophy or LAE

37 Differential Diagnosis: Painless Ascites with high CVP and no edema Malignant Ascites TB Peritonitis Cardiac Ascites: Constrictive Pericarditis :? underlying cause, what next test could confirm this if available Mitral Stenosis Hyperthyroid Cardiomyopahty Restrictive Cardiomyopathy

38 EMF: Endomyocardial Fibrosis most common restrictive CM in the world centered in E.Africa (rural SW Uganda) >25% cases of CHF widespread endocardial fibrosis rigid ventricles and a non-dilated heart, often murmurs due to the tethering of valve apparatus Patchy geographical and ethnic distribution Nigeria, India, Brazil, Columbia, Sri Lanka and Middle East

39 EMF: Endomyocardial Fibrosis Poverty as risk factor Unknown etiology Like Loeffler Endocarditis hypereosinophilic syndromes ?damage by eosinophils due to multiple episodes of parasitic infection Other theories: nutrient, micronutrient imbalance and gnetics

40 Case 2: Question 1 Age and location Recent death of partner NON-pitting Bilateral Edema Temporal relation of swelling to skin lesions Painless Lymphadenopathy

41 Case 2: Question 2 DDX: Filarial Elephantiasis Fungal Infection Chronic Renal Failure Congestive Heart Failure Chronic Liver Failure Chronic Venous Stasis Kaposi Sarcoma

42 Case 2: Testing Urine Dip: Spec Grav: 1.015, (-) nitrites/WBCs/RBCs/protein, no casts, glucose or ketones HIV rapid (+) Creatinine wnl

43 Narrow our Differential DDX: Filarial Elephantiasis Fungal Infection Chronic Renal Failure Congestive Heart Failure Chronic Liver Failure Chronic Venous Stasis Kaposi Sarcoma

44 ? Kaposis Sarcoma Stage 4 AIDS CD4 count Any other AIDS defining diagnoses Pregnancy Test Skin Scraping with KOH Punch Biopsy Look for Visceral Involvement Test Child and all partners R/o STIs, TB

45 Treatment HAART Chemotherapy, Surgical Excision Demanding Resources: Tertiary Care hospital if available
