    Study Notes

    Asthma Management

    • Cost-effective peak expiratory flow meters should be regularly used to monitor respiratory function at home, and daily readings should be recorded in journals.
    • Emphasizing the importance of allergen avoidance is crucial in preventing asthma attacks for individuals with known allergies.
    • The choice of anti-asthmatic drugs depends on the type and severity of asthma, as well as whether the drug is intended for long-term control or immediate relief.

    Tuberculosis

    • Tuberculosis is a significant infectious disease in humans caused by the communicable bacterium Mycobacterium tuberculosis.
    • It poses a major global health challenge, leading to illness and fatalities across various populations worldwide.
    • The transmission of the disease occurs through the inhalation of infected droplets, typically exhibiting a prolonged dormant period.
    • Replication of M.tuberculosis triggers an inflammatory and granulomatous response in the host, resulting in the development of typical pulmonary and systemic symptoms.

    Epidemiology of Tuberculosis

    • Tuberculosis is globally prevalent, with an incidence of 9 to 10 million cases.
    • Approximately one-third of the global population, equivalent to 2 billion people, is estimated to be infected with the disease.

    Pathophysiology and Complications of Tuberculosis

    • Tuberculosis can affect virtually any organ in the body, though the lungs are the most commonly affected site.
    • The typical progression of primary pulmonary TB involves the inhalation of infected droplets, which are then carried into the alveoli.
    • Within the alveoli, macrophages engulf the bacteria, leading to replication within these cells.
    • Local spread of the infection occurs, involving regional (hilar) lymph nodes.

    Clinical Presentation of Tuberculosis

    • Symptoms include cough, fatigue, malaise, loss of appetite, unexplained weight loss, night sweats, and fever.
    • Fever typically occurs in the evening or at night and is accompanied by profuse sweating.
    • Specific symptoms related to the affected organ vary.
    • Persistent cough, often appearing late in the disease course, is a common symptom of pulmonary TB, especially in cases involving cavities.

    Laboratory and Diagnostic Findings of Tuberculosis

    • Laboratory tests aim to ascertain whether the patient has an active infection or latent tuberculosis infection (LTBI).
    • Active infection is indicated by a positive acid-fast bacillus sputum smear, the presence of symptoms, and observable characteristic changes in chest radiography.

    COPD

    • Chronic obstructive pulmonary disease (COPD) is a condition characterized by persistent airflow limitation from the lungs, which is not fully reversible.
    • Chronic bronchitis is specifically defined as a state linked to the chronic inflammation of the bronchi, resulting in excessive production of tracheobronchial mucus.

    Epidemiology of COPD

    • COPD is one of the most prevalent diagnoses encountered in medical practice, encompassing the older terms chronic bronchitis and emphysema.
    • Globally, tobacco smoking is the primary cause of COPD.

    Pathophysiology and Complications of COPD

    • Long-term exposure to cigarette smoke induces pathophysiological responses in the airways and lung tissue, particularly in chronic bronchitis, which affects both large and small airways.
    • In the large airways, tobacco smoke and irritants lead to thickened bronchial walls, inflammatory cell infiltration, increased size of mucous glands, and goblet cell hyperplasia.
    • In the small airways, obstruction is intensified by narrowing, scarring, heightened sputum production, mucous plugging, and the collapse of peripheral airways due to the loss of surfactant.

    COPD and Asthma Management

    Dental Considerations

    • Dentists should promptly refer patients with COPD to physicians for further evaluation
    • Dental health providers can contribute to preventing disease progression by encouraging smokers to quit
    • Providing information on smoking-related diseases and promoting healthy living can motivate patients to consider quitting

    • Evaluate the severity and control of the patient's respiratory disease before initiating dental care
    • Unstable patients should be referred for medical evaluation if they display symptoms like shortness of breath, productive cough, upper respiratory infection (URI), or oxygen saturation (O2 sat) below 91%

    Airway and Breathing

    • Focus on avoiding factors that could further depress respiration in stable patients (O2 sat >95%)
    • Pulse oximetry monitoring is recommended
    • Humidified low-flow oxygen (2-3 L/min) may be provided if O2 sat is below 95%

    Capacity to Tolerate Care

    • Dental care is generally suitable for patients with stages I to III COPD, but should be avoided in those with stage IV (very severe) COPD
    • Coexisting cardiovascular disease requires stress reduction measures and vital sign monitoring

    COPD Definition and Causes

    • Chronic obstructive pulmonary disease (COPD) is a progressive disease characterized by long-term exposure to tobacco smoke, leading to airflow limitation
    • Tobacco smoking is the primary cause of COPD, affecting approximately 12.5% of current smokers, 9% of former smokers, and 8% of those exposed to passive smoke
    • Other causes include long-term exposure to occupational and environmental pollutants, the absence or deficiency of α1-antitrypsin, and genetic factors

    Pathophysiology and Complications

    • Long-term exposure to cigarette smoke induces pathophysiological responses in the airways and lung tissue
    • Chronic bronchitis affects both large and small airways, leading to thickened bronchial walls, inflammatory cell infiltration, and increased size of mucous glands
    • Complications include progressive dyspnea, hypercapnia, recurrent pulmonary infections, pulmonary hypertension, cor pulmonale, and sleep disturbances

    Clinical Presentation

    • COPD typically manifests after the age of 40, with symptoms including chronic cough, intermittent or continuous sputum production, and progressive dyspnea
    • Weight loss and decreased exercise capacity become apparent as the disease advances
    • Comorbid conditions associated with COPD include cardiovascular disease, respiratory infections, osteoporosis, and fractures

    Asthma Definition and Management

    • Asthma is a chronic inflammatory disease characterized by recurring episodes of wheezing, coughing, chest tightness, and shortness of breath
    • Most patients can expect a reasonably good prognosis, especially those in whom the disease develops during childhood
    • Laboratory tests lack specificity, and no single test is definitive for asthma diagnosis
    • Treatment strategies involve localized delivery of medications to the airways using inhalers, addressing contributing factors, and managing concurrent conditions

    What is Diabetes?

    • Diabetes mellitus is a group of metabolic diseases characterized by high blood glucose levels (hyperglycemia) and the inability to produce and/or use insulin.
    • It is a chronic condition that can affect people of all ages.

    Complications of Diabetes

    • Persistent hyperglycemia leads to metabolic and vascular complications.
    • Vascular complications include accelerated onset of nonspecific atherosclerosis and microangiopathy, particularly affecting the eyes and kidneys.
    • Retinopathy and nephropathy are common complications in people with chronic diabetes.

    Importance of Diabetes in Dentistry

    • Dentists will have many patients with diabetes and are in a position to detect undiagnosed or poorly controlled cases.
    • Diabetes affects oral health, and oral health affects diabetes.
    • Dentists and hygienists must be able to provide care to patients with diabetes without endangering their well-being.

    Epidemiology of Diabetes

    • Type 2 diabetes is the most prevalent type of diabetes mellitus.
    • The incidence of type 2 diabetes increases with age, primarily affecting adults.
    • Type 1 diabetes is more prevalent than type 2 diabetes in people under 20 years old.

    Pathophysiology and Complications

    • Diabetes leads to long-term microvascular and macrovascular complications.

    Clinical Presentation and Diagnostic Criteria

    • Symptoms of diabetes usually resolve when plasma glucose levels are below 11.1 mmol/L.

    Medical Management of Diabetes

    • Goals of therapy for type 1 or type 2 diabetes include: eliminating symptoms related to hyperglycemia, reducing long-term complications, and allowing patients to achieve a normal lifestyle.
    • Physicians should identify a target level of glycemic control for each patient, provide necessary resources, and monitor and treat complications.

    Adrenal Gland Disorders

    • The adrenal glands are small endocrine glands located bilaterally at the superior pole of each kidney
    • The adrenal medulla functions as a sympathetic ganglion and secretes epinephrine
    • The adrenal cortex secretes several steroid hormones with multiple actions
    • Cortisol acts as an insulin antagonist, increasing blood levels and peripheral use of mineralocorticoid, glucocorticoid, and inflammation

    Hyperadrenalism

    • Hyperadrenalism is characterized by excessive secretion of adrenal cortisol, mineralocorticoids, androgens, or estrogen in isolation or combination
    • Syndromes caused by hyperadrenalism:
      • Androgen-related disorders (rare, primarily affect the reproductive organs)
      • Mineralocorticoid excess (primary aldosteronism, associated with hypertension, hypokalemia, and dependent edema)
      • Glucocorticoid excess (Cushing syndrome, causes weight gain, moon facies, buffalo hump, abdominal striae, hypertension, hirsutism, and acne)

    Cushing Syndrome

    • Caused by glucocorticoid excess, either endogenous or exogenous
    • Classical symptoms: weight gain, moon facies, buffalo hump, abdominal striae, hypertension, hirsutism, and acne

    Adrenal Insufficiency

    • Divided into three categories: primary, secondary, and tertiary
    • Primary adrenocortical insufficiency (Addison disease): destruction or removal of the adrenal cortex
    • Secondary adrenocortical insufficiency: pituitary disease or unresponsiveness of the adrenal glands to ACTH
    • Tertiary adrenal insufficiency: impaired function of the hypothalamus, often caused by chronic use of corticosteroids

    Dental Management

    • Patient assessment: type of adrenal disorder, blood glucose levels, and wound healing
    • Hyperadrenalism:
      • Blood glucose levels should be determined
      • Invasive procedures should be performed during periods of good glucose control
      • Follow-up appointments should be arranged to assess proper wound healing
    • Dental management of patients taking steroids:
      • Assess which type of insufficiency
      • Bleeding is not an issue unless anticoagulant is taken
      • Blood pressure should be monitored, and patient follow-up is necessary
      • Avoid phenobarbital use and discontinue use of certain medications 24 hours before surgery

    Adrenal Crisis

    • Blood pressure very low, below 100/60 mmHg
    • Immediate treatment requires:
      • Proper patient positioning (head lower than feet)
      • Fluid replacement
      • Administration of vasopressors
      • Administration of 100 mg of hydrocortisone or 4 mg of dexamethasone IV
      • Immediate transportation to a medical facility
