  1. Carbuncle with Ipsilateral Facial Cellulitis in a Diabetic Big Group Discussion Group C3B Malig-Marayag

  2. Infections in Diabetics • Diabetic patients have greater frequency and severity of infection due to: • Diminished vascularization • Hyperglycemia • Impairs killing of micro-organisms by neutrophils and macrophages • Interferes with T lymphocyte function • Aids in colonization and growth of a variety of organisms (Candida and other fungal species Oxford Textbook of Medicine, 4th ed. Harrison’s Principles of Internal Medicine, 17th ed.

  3. Cellulitis • Acute suppurative inflammation involving the subcutaneous tissue • Characterized by: • Localized pain, erythema, swelling, heat • Differentiated from erysipelas: • Lesion is not raised • Line between the involved and uninvolved tissue is indistinct Harrison’s Principles of Internal Medicine, 17th ed. Jawetz, Melnick & Adelburg’s Medical Microbiology, 24th ed.

  4. Cellulitis • Mild local erythema and tenderness • Rapidly becomes intense and spreads • Area becomes infiltrated and pits on pressure • Central part may become nodular and develop a vesicle that ruptures and discharges pus and necrotic material • Malaise • Fever and chills Andrews’ Diseases of the Skin: Clinical Dermatology, 10th ed.

  5. Cellulitis • Most commonly caused by indigenous flora • Staphylococcus aureus – usually associated with an abscess, folliculitis, or foreign body • Streptococcus pyogenes – spreads more rapidly; associated with fever and lymphangitis • Bacteria may gain access to the epidermis through: • Cracks in the skin, abrasions, cuts, burns, insect bites, surgical incisions, intravenous catheters Harrison’s Principles of Internal Medicine, 17th ed.

  6. Cellulitis • Associated with predisposing conditions • Streptococcus agalactiae – diabetes mellitus, peripheral vascular disease • Haemophilus influenzae – causes periorbital cellulitis children with sinusitis, otitis media or epiglottitis Harrison’s Principles of Internal Medicine, 17th ed.

  7. Facial Cellulitis • People with certain risk factors are more likely than others to develop facial cellulitis. Facial cellulitis risk factors include: • Problems in the lymphatic system • Upper respiratory infection • Infection of the teeth or middle ear http://skin.emedtv.com/facial-cellulitis/facial-cellulitis-p2.html

  8. Facial Cellulitis • in the facial region the most common portals of entry are dental infections, sinusitis, upper respiratory tract infection, surgery, and trauma Facial cellulitis associated with Pseudomonas aeruginosa complicating ophthalmic herpes zoster Laura Atzori MD1, Caterina Ferreli MD1, Myriam Zucca MD1, Daniela Fanni MD2, and Nicola Aste MD1Dermatology Online Journal 10 (2): 20

  24. Laboratory Results

  25. DIAGNOSTIC TEST FOR DIABETES MELLITUS

  26. National Diabetes Group and WHO diagnostic criteria for DM: • Fasting plasma glucose level at or above 126 mg/dL (7.0 mmol/L). • Plasma glucose at or above 200 mg/dL (11.1 mmol/L) two hours after a 75 g oral glucose load as in a glucose tolerance test. • Symptoms of hyperglycemia and plasma glucose at or above 200 mg/dL (11.1 mmol/L). Harrison’s 17th Edition

  27. Fasting blood glucose test • The most common test for diagnosis of diabetes. • blood glucose levels are checked after fasting for between 12 and 14 hours. • Patients with fasting glucose levels from 100 to 125 mg/dL (6.1 and 7.0 mmol/L) are considered to have impaired fasting glucose • Patients with diabetes may be asked to delay their diabetes medication or insulin dose until the test is completed. http://ovennewyork.com/diabetes-mellitus-laboratory-tests-or-diagnostic-tests.html

  28. Random blood glucose test • blood glucose levels are checked at various times during the day, and it doesn’t matter when you last ate. • Blood glucose levels tend to stay constant in a person who doesn’t have diabetes. http://ovennewyork.com/diabetes-mellitus-laboratory-tests-or-diagnostic-tests.html

  29. Oral glucose tolerance test (OGTT) • FBS is obtained before the ingestion of a 50- to 200-g glucose load (usual amount is 75 g), • blood samples are drawn at ½, 1, 2, and 3 hours (may be 4- or 5-hour sampling). • Blood samples are checked at regular intervals for two hours. • Glucose tolerance tests are used when the results of the fasting blood glucose are borderline. http://ovennewyork.com/diabetes-mellitus-laboratory-tests-or-diagnostic-tests.html

  30. They are also used to diagnose diabetes in pregnancy (gestational diabetes). • NORMAL: the results of the glucose tolerance test will show that their blood sugar levels fall within the normal range • Patients with plasma glucose at or above 140 mg/dL or 7.8 mmol/L, but not over 200, two hours after a 75 g oral glucose load are considered to have impaired glucose tolerance.

  31. Glycated Hemoglobin (Glycohemoglobin, HbA1c) for Diabetes Mellitus • Measures glycemic control over a 60- to 120-day period by measuring the irreversible reaction of glucose to hemoglobin through freely permeable erythrocytes during their 120-day lifecycle. • While not used for diagnosis, an elevated level of glucose irreversibly bound to hemoglobin of 6.0% or higher (the 2003 revised U.S. standard) is considered abnormal by most labs http://ovennewyork.com/diabetes-mellitus-laboratory-tests-or-diagnostic-tests.html

  32. GOALS OF THERAPY • Eliminate symptoms related to hyperglycemia • Reduce or eliminate the long-term microvascular and macrovascular complications of DM • Allow the patient to achieve as normal a lifestyle as possible Harrison’s 17th Edition

  33. Harrison’s 17th Edition

  34. Insulin Insulin vs. hypoglycemics Oral hypoglycemics Should not be used in severly ill patients with type 2 DM Insulin secretagogues: such as sulfonlyureas are effective in individual with relatively recent onset (<5 yrs) of type 2DM Biguanides (metformin): should not be used in patients with renal insufficency [serum creatinine > 133umol/L (1.5mg/dL) in men] Should be discontinued in patients who are severly ill, in patients who can take nothing orally and in thoe receiving radiograohic contrast material α- glucosidase inhibitors (acarbose and miglitol): should not be used in patients with inflammatory bowel disease, gastroparesis or a serum creatinine >177umol/L (2.0mg/dL) Considered initial therapy in type 2 DM, particularly in lean individuals or those with severe weight loss, in individuals with underlying renal or hepatic disease that precludes oral glucose-lowering agents, or in individuals who are hospitalized or acutely ill A long acting insulin (lantus) is best for the patient because if his age etc. since you don’t have to take it often.

  35. Patient education about DM, nutrition and exercise • Patient with DM should receive education about: • Nutrition • Exercise • Care of diabetes during illness • Medications to lower the plasma glucose • Continuing process with regular visits for reinforcement • Diabetes self-management education (DSME) Harrison’s 17th Edition

  36. Diabetes education • Self-monitoring of blood glucose • Urine ketone monitoring (type 1) • Insulin administration • Guidelines for diabetes management during illness • Management of hypoglycemia • Foot and skin care • DM management before, during and after exercise • Risk-factor-modifying activities Harrison’s 17th Edition

  37. Nutrition • Medical Nutrition Therapy (MNT) • Modest caloric reduction • Reduced fat intake • Increased physical activity • Reduction of hyperlipidemia and hypertension Harrison’s 17th Edition

  38. Exercise • CV risk reduction • Reduced BP • Maintenance of muscle mass • Reduction in body fat and weight loss • Lowering plasma glucose • Increasing insulin sensitivity *ADA recommends 150 min/week (distributed over at least 3 days) Harrison’s 17th Edition

  39. Monitoring the level of glyceminc control • Plasma glucose measurements by the patient and assessment of long-term control by the physician • Measurement of A1C and review of the patient’s self-measurement of plasma glucose Harrison’s 17th Edition

  40. Self-monitoring of Blood Glucose • Standard of care in diabetes management and allows the patient to monitor his/her blood glucose at any time • Glucose monitors can rapidly and accurately measure glucose in small amounts of blood (3-10 µL obtained from the fingertip *individuals with type 2 DM who are taking insulin should utilize SMBG more frequently than than those on oral agents Harrison’s 17th Edition

  41. Assessment of Long-term Glycemic Control • Measurement of glycated hemoglobin • Plasma glucose is consistently elevated = increase in nonenzymatic glycation of hemoglobin • Reflects the glycemic history over the previous 2-3 months Harrison’s 17th Edition

  42. CELLULITIS

  43. DIAGNOSTIC PLANS FOR CELLULITIS CT scan with contrast of the paranasal and neck area pharyngolaryngoscopy Blood culture Aspiration CT scan

  44. *As clinically indicated; • †Ulcerated lesions should be cleaned and debrided before having wound base swabbed; • ‡Most useful if vesicle/bullae or fluid abscess present; • §Seek out bone trauma and air fluid levels; • ¶Indications –neurological deficits, vision nonassessable, proptosis/deteriorating acuity or colour/bilateral edema/ophthalmoplegia, no improvement after 24 h and swinging pyrexia not resolving within 36 h (for head only); • **Only if central nervous system involvement suspected

  45. Diagnosis • Based on appearance of the skin and patient history • Drainage from an abscess or weeping wound associated with cellulitis should be sent for culture and sensitivities. • Material from needle aspiration of inflamed skin or skin biopsy can be cultured in cases of cellulitis without purulence, abscess, or a necrotic • Indications for blood cultures include significant fever and chills, severe immunocompromise, periorbital cellulitis, and cellulitis superimposed on lymphedema. • A polymorphonuclear leukocytosis is often present with cellulitis; a complete blood cell count and differential may help gauge the severity of infection and the hematologic response.
