Diabetes Mellitus: Etiology and Epidemiology!

 DIABETES MELLITIS



Definition:

Diabetes Mellitus (DM) describes a group pf chronic metabolic disorders characterized by hyperglycemia that may result in long-term microvascular, macrovascular and neuropathic complications. these complications contribute to diabetes being the leading cause of:
a) new cases of blindness among adults
b) end stage renal diseases
c)non-traumatic lower limb amputations


Etiology:

The increasing prevalence is caused by three influences:

1. ethnicity        2. Lifestyle       3. Age


Types:

a) Type 1 DM

b) Type 2 DM

c) Type 1.5DM

d) Gestational Diabetes Mellitus (GDM)


** In type 1 DM; the body fails to make insulin. In type 2 DM; body either develops resistance to insulin or not enough insulin is produced to lower the Blood glucose levels**


Epidemiology

  • The worldwide prevalence of DM has risen over past two decades with an estimation of 30 million cases in 1985 to 177 million cases in 2000.
  • Based on current trends, >30million individuals will have diabetes by 2030.
  • Pakistan is among the top countries to report the most cases of diabetes.

Drug-Induced Ototoxicity!

 DRUG-INDUCED OTOTOXICITY What is drug Induced Ototoxicity? Drug-Induced ototoxicity can affect hearing (auditory or cochlear function0, balance (vestibular function) depending on the drug. Drugs of almost every class have been reported to produce tinnitus (sounds in ear), as have placebos. The following agents are associated with measurable changes in hearing or vestibular defect when administered systemically. 1. AMINOGLYCOSIDES: Aminoglycosides antibiotics can cause cochlear or vestibular toxicities. Cochlear toxicity: occurs as progressive hear loss, starting with highest tones and advancing to lower tones. Thus, considerable damage can occur before the patient recognizes it. S ymptoms of Vestibular damage : include;  Dizziness Vertigo Ataxia Both forms of ototoxicity are bilateral and potentially reversible, but permanent damage is common and can progress even after discontinuation of aminoglycosides. Clinically detectable ototoxicity in as many as 5% patients. Most amin...

Diabetes Mellitus: Non-Pharmacological Therapy--MNT!

 NON PHARMACOLOGICAL THERAPY  MNT Glycemic Index Dietary supplements Weight measurements Physical Activity Psychological assessment Immunizations 1. MEDICAL NUTRITION THERAPY (MNT)  " Medical Nutrition Therapy (MNT) is a term used by the ADA to describe the optimal condition of caloric intake with other aspects of diabetes therapy (Insulin, Exercise, Weight loss)". The ADA has issued recommendations for three types of MNT: Primary prevention measures of MNT are directed at preventing or delaying the onset of type 2 Diabetes in high-risk individuals (obese or with pre-diabetes) by promoting weight reduction. Secondary prevention measures of MNT are directed at preventing or delaying-related complications in diabetic individuals by improving glycemic control. Tertiary prevention measures of MNT are directed at managing diabetes-related complications (cardiovascular disease, neuropathy) in diabetic individuals. Despite the popular notion, there is not any " Diabetic diet...

Medical Emergency- Cardiac Arrest and Basic Life Support (BLS)!

  MEDICAL EMERGENCY- CARDIAC ARREST AND BASIC LIFE SUPPORT Definition: " Cardiac Arrest is a medical emergency requiring a systematic approach". Early recognition must be followed by prompt, effective application of Basic Life Support (BLS) techniques to sustain the patient until Advanced Life Support (ALS) capabilities are available. Management: The management of Cardiac Arrest is a 4-step approach: Recognition and Assessment BLS Advanced Cardiovascular Life Support (ACLS) Post-resuscitation Care 1. RECOGNITION AND ASSESMENT Verify that the respiration and circulation have ceased: Loss of consciousness Loss of functional ventilation (respiratory arrest or inadequate respiratory effort) Loss of functional perfusion (No pulse). 2. BASIC LIFE SUUPORT (BLS) The goal in cardiac arrest is the restoration of spontaneous circulation (ROSC). The first step towards achieving this ROSC goal is prompt initiation of BLS, where the goal is to rapidly and effectively perfuse the tissues wi...
