Skin Diseases , Natural Resistance of the Skin 1.Dryness of the Skin: The relative dryness of the skin surface limits bacterial growth. 2.Constant Cell Shedding: The skin’s horny layer constantly sheds cells, helping remove potential pathogens. 3.Sebaceous Secretions: Sebum contains natural antibacterial substances that help inhibit bacterial colonization. 4.Low pH Environment: The skin's acidic environment (pH 5.5) discourages bacterial growth. 5.Normal Skin Flora: The natural microbial flora of the skin competes with potential pathogens (bacterial interference). Common Bacterial Skin Infections and Causes 1.Primary Bacterial Infections: 1. Affect healthy skin. 2. Common infections: impetigo, cellulitis, erysipelas. 2.Secondary Bacterial Infections: 1. Occur in previously damaged skin (e.g., diabetic foot ulcers, pressure sores). 2. Often polymicrobial (multiple bacterial species). Common Pathogens: Gram-positive: Staphylococcus aureus, Streptococcus pyogenes. Gram-negative: Pseudomonas aeruginosa, Escherichia coli. Common Bacterial Skin Infections 1.Staphylococcus aureus Infections: 1. Impetigo 2. Cellulitis (occasionally) 3. Folliculitis 4. Furunculosis 5. Carbuncle 2.Streptococcus pyogenes Infections: 1. Cellulitis 2. Erysipelas 3. Impetigo 4. Bacterial Intertrigo 5.

Pseudomonas aeruginosa  Impetigo Definition: Impetigo is a common, highly contagious bacterial skin infection affecting the epidermis. It primarily occurs in children and often spreads through close contact. Etiology: Causative Organisms: Streptococcus pyogenes and Staphylococcus aureus (including MRSA). Common Sites: Most frequently seen on the face but can occur anywhere on the body. Pathophysiology: Minor skin trauma, such as cuts, scratches, or insect bites, allows bacteria to penetrate the superficial layers of the skin, leading to infection. Hot and humid weather can facilitate the colonization and spread of these organisms. Epidemiology: 1. Most common in children. 2. More prevalent in warm, humid climates. 3. Spread is facilitated by close contact, poor hygiene, and crowded living conditions. Clinical Presentation: 1.Non-Bullous Impetigo: 1. Begins as small, fluid-filled vesicles that quickly become pus-filled. 2. These vesicles rupture, releasing a purulent discharge that dries, forming characteristic yellowish or honey-colored crusts. 3. Commonly itchy (pruritus), and scratching can lead to further spread of the infection. 2.Bullous Impetigo: 1. Starts with larger, fluid-filled blisters (bullae) containing clear or yellowish fluid. 2. Bullae eventually rupture, leaving behind thin brown crusts. Non-Bullous Impetigo Bullous Impetigo  Diagnosis: Primarily clinical, based on characteristic appearance. Laboratory tests are generally unnecessary unless infection is recurrent or resistant.  Treatment Goals 1. Eradicate the infection promptly. 2. Relieve symptoms like itching and discomfort. 3. Prevent the formation of new lesions and spread to others. 4. Reduce risk of complications, such as cellulitis or post-streptococcal glomerulonephritis. 5. Prevent recurrence. Treatment Options: 1.Non-Pharmacologic Therapy: 1. Gently washing and soaking lesions with warm, soapy water can provide relief and help remove crusts. 2.Pharmacologic Therapy: 1. Topical Antibiotics: For limited or mild cases, apply mupirocin or retapamulin ointment twice daily for 5 days. 2. Systemic Antibiotics: For more extensive cases or multiple lesions: 1. CA -MSSA Coverage: Dicloxacillin or a first-generation cephalosporin like cephalexin. 2. CA -MRSA Coverage: If MRSA is suspected or confirmed, options include clindamycin, doxycycline, or trimethoprim-sulfamethoxazole. 3. Penicillin V can be used if S. pyogenes is identified as the sole cause. MUPIROCIN  Monitoring: Clinical response is expected within 5–7 days. If symptoms persist or worsen, reassess for possible resistance or noncompliance, and consider a follow-up culture.  Erysipelas Definition: Erysipelas is an acute bacterial infection affecting the dermis layer of the skin. Most Common Cause: Streptococcus pyogenes Common Sites of Infection: Face Lower extremities Typically unilateral (affects one side of the body) Diagnosis Clinical Diagnosis Based primarily on clinical symptoms and physical examination. Laboratory Tests Complete Blood Count (CBC): Leukocytosis is commonly seen. C-Reactive Protein (CRP): Generally elevated, indicating inflammation. Cultures: Causative organisms are usually challenging to culture. Cultures may be considered in more severe or atypical cases (e.g., fluid-filled blisters).  Clinical Picture Pain: The infected area is often painful, with a burning sensation. Lesion Appearance: Intensely erythematous (red) and edematous (swollen). Raised border that is sharply demarcated from uninfected skin. Additional Symptoms: Leukocytosis (high WBC count) Elevated CRP Mild fever  Treatment Drug of Choice: Penicillin (oral or IV depending on clinical severity) Mild-to-Moderate Cases (Outpatient Treatment) IM procaine penicillin G or oral penicillin V for 7–10 days. Serious Infections (Inpatient Treatment) IV aqueous penicillin G For Penicillin-Allergic Patients: Clindamycin can be used as an alternative Monitoring and Expected Recovery Improvement: Marked improvement is typically seen within 48 hours. Transition: Patients may be switched from IV to oral penicillin once improvement is evident. Resolution: Temperature and WBC count should normalize within 48–72 hours. Erythema, edema, and pain gradually resolve as the infection clears.  Cellulitis is an acute bacterial infection that affects the epidermis and dermis layers of the skin and can spread within the superficial fascia. It is typically characterized by inflammation with minimal or no necrosis of the tissue. Common Causes: Streptococcus pyogenes Staphylococcus aureus (occasionally) Risk Factors: Injection drug use Minor trauma, abrasions, ulcers, or recent surgery Poor nutrition Compromised immunity  Pathogenesis Bacteria often enter through breaks in the skin due to minor trauma, abrasions, ulcers, or surgery. The infection can spread through lymphatic tissue and potentially enter the bloodstream, making it a serious condition.  Classification of Cellulitis 1.Purulent Cellulitis 1. Involves purulent drainage or exudate, without a simple drainable abscess. 2.Non-Purulent Cellulitis 1. Lacks purulent drainage or exudate, and no abscess is present.  Clinical Presentation Local Symptoms: Erythema and edema Warmth over the affected area Lesions that are non-elevated and have poorly defined margins Inflammation with little or no necrosis of soft tissue Systemic Symptoms: Fever Chills Malaise Tender lymphadenopathy  Diagnosis Clinical Evaluation Diagnosis is primarily clinical, based on presenting symptoms and physical examination. Laboratory Tests CBC: Leukocytosis is commonly observed. Blood Cultures: Rarely positive, but may be recommended in severe systemic cases or for immunocompromised patients.  Treatment Non-Pharmacologic Therapy Elevate and immobilize the affected area to reduce swelling. Apply cool, sterile saline dressings for pain relief, followed by moist heat to localize infection. Surgical incision and drainage are rarely needed for uncomplicated cases.  Complications Local abscess Septicemia Osteomyelitis Septic arthritis hair  Folliculitis Definition: Folliculitis is an infection of the hair follicles characterized by clustering, pruritic, and erythematous papules localized to the hair follicles. Clinical Presentation: Papules develop in areas subject to friction and perspiration. They may evolve into pustules that can spontaneously rupture within several days. Systemic signs are uncommon. Treatment: Non-pharmacologic: Warm moist compresses. Topical Therapy (applied 2-4 times daily for 7 days): Clindamycin topical Erythromycin topical Mupirocin topical  Furuncles Definition: Furuncles, or boils, are inflammatory nodules involving a hair follicle, which can occur as singular or multiple lesions. Clinical Presentation: Lesions start firm, tender, and red, progressing into pustules. They often drain spontaneously. Systemic signs are uncommon. Treatment: For Small Furuncles: Moist heat to promote localization and drainage of pus. For Large/Multiple Furuncles: Incision and drainage. For Moderate to Severe Infections (especially with systemic signs): Antibiotics such as Bactrim or doxycycline for 5-10 days, especially due to high suspicion of CA-MRSA.  Carbuncles Definition: Carbuncles form when adjacent furuncles coalesce, creating a larger, inflamed area. Clinical Presentation: They present as broad, swollen, erythematous, deep, and painful follicular masses. Commonly develop on the back of the neck. More likely in patients with diabetes mellitus. Systemic signs may include fever, chills, malaise, and bacteremia with potential secondary spread to other tissues. Diabetic Foot Infections. Treatment: Similar to furuncles, including incision and drainage. Systemic antibiotics may be required for severe cases or if systemic signs are present. Evaluation of Therapeutic Outcomes for Folliculitis, Furuncles, and Carbuncles 1. Many follicular infections resolve spontaneously without intervention. 2. If lesions do not respond to moist heat and topical agents, incision may be necessary. 3. Following drainage, most lesions begin to heal. 4. Patients unresponsive to systemic antibiotics or with recurrent infections should undergo culture and sensitivity testing to guide antibiotic selection.  Diabetic Foot Infections Definition DFIs are classified into three primary types based on infection location and presentation: 1.Deep Abscesses - localized collections of pus within deep tissue. 2.Cellulitis of the Dorsum - a diffuse infection on the top part of the foot. 3.Mal Perforans Ulcers - chronic, pressure-induced ulcers on the sole, common in patients with neuropathy.  Etiology: Mild Infections: Typically monomicrobial (involving a single pathogen). Moderate to Severe Infections: Usually polymicrobial, involving multiple pathogens: Common organisms include: Staphylococcus aureus Streptococcus species Enterococcus Escherichia coli Klebsiella Pseudomonas aeruginosa Bacteroides fragilis  Classification Mild: Local infection, erythema ≤2 cm, no SIRS. Moderate: Erythema >2 cm, deeper structures, no systemic symptoms. Severe: With 2+ SIRS criteria (requires hospitalization).  Pathophysiology Three main factors contribute to the development of DFIs: 1.Neuropathy - sensory loss increases risk of unnoticed injury. 2.Ischemia - poor lower limb perfusion, commonly due to vascular complications, impairs healing. 3.Immunologic Defects - reduced immune function in diabetes leads to higher infection risk and impaired response.  SIRS SIRS criteria help assess the body's systemic inflammatory response, guiding clinicians in identifying serious conditions like sepsis or non- infectious systemic inflammation.  Clinical Presentation Clinical Presentation Infections often extend beyond what appears on the surface due to angiopathy and neuropathy, which may mask symptoms. Signs and Symptoms: Swelling or erythema (without pain awareness due to neuropathy) Presence of pus Mildly elevated or normal temperature Lesions of varying sizes Tenderness and foul-smelling odor (suggesting anaerobic infection)  Diagnosis and Assessment Laboratory Tests Culture and Sensitivity Testing: Use specimens from deep tissue or pus from wound base. Culture for both aerobic and anaerobic organisms.  Nonpharmacologic Therapy 1.Debridement: Remove necrotic tissue and consider wound drainage or amputation if necessary. 2.Wound Care: 1. Keep wounds clean, changing dressings 2-3 times daily. 3.Edema Control: 1. Restrict to bed rest with leg elevation if edema is present. 2. Ensure pressure relief on the affected foot to aid healing.  Pharmacologic Therapy Mild Infections Without MRSA Risk: Dicloxacillin, Nafcillin, Cephalexin, Cefazolin, Levofloxacin, Clindamycin. With MRSA Risk: Trimethoprim-sulfamethoxazole (Bactrim). Moderate to Severe Infections For polymicrobial infections: Ampicillin/sulbactam, Ertapenem, Cefoxitin, Moxifloxacin, Ciprofloxacin or Levofloxacin + Clindamycin, or Tigecycline. With MRSA Coverage: Vancomycin, Linezolid, Daptomycin. For Pseudomonas Coverage: Piperacillin/tazobactam, Ceftazidime, Cefepime, Meropenem, Imipenem. Duration of Therapy No Amputation: Mild: 1-2 weeks Moderate to Severe: 2-3 weeks Osteomyelitis (if present): extended duration required Post-Amputation: No residual infected tissue or bone: 2-5 days Residual infected tissue: 1-3 weeks Residual infected bone: 4-6 weeks Monitoring and Complications Monitoring: Evaluate response 48-72 hours after antibiotic initiation. Adjust regimen based on clinical response or when culture results are available. Complications: Osteomyelitis is a common complication, occurring in 30-40% of cases. Acne vulgaris / Definition of Acne Vulgaris in Points Chronic Condition: Acne vulgaris is a long-lasting skin disorder that can persist for years if untreated. Affects Pilosebaceous Units: It involves hair follicles and sebaceous (oil) glands, primarily on the face, chest, and back. Epidemiology 1. Prevalence: Acne affects 80-90% of adolescents and can persist into adulthood, impacting up to 20% of adults. 2. Age Distribution: Typically begins in puberty (ages 10-13) and peaks in teenage years, but 12-20% of adults, especially women, continue to experience it, often due to hormonal factors. 3. Gender Differences: Acne is slightly more common in males during adolescence but is more prevalent in adult females due to hormonal fluctuations. 4. Psychosocial Impact: Acne can significantly affect self-esteem, social behavior, and mental health, particularly in adolescents, highlighting the need for effective treatment and support.  Causes of Acne Vulgaris 1. Hormonal Changes: Increased androgen levels during puberty and other hormonal fluctuations (e.g., menstruation, pregnancy, PCOS) stimulate excess oil production in the skin. 2. Excess Sebum Production: Overproduction of oil can clog hair follicles, leading to acne lesions. 3. Bacterial Growth: Cutibacterium acnes bacteria thrive in clogged pores, causing inflammation and acne lesions. 4. Inflammation: The body’s immune response to bacteria and clogged pores causes redness, swelling, and pain. 5. Genetic Factors: Family history increases susceptibility to acne. 6. Diet and Lifestyle: High dairy, sugar, and refined carbs can exacerbate acne. Stress, certain medications, and environmental pollutants also contribute. 7. Cosmetic Products: The use of comedogenic or oil-based skincare and makeup products can block pores and trigger acne. Types of Acne Vulgaris ‫د‬ Classification Based on Severity  Goals of therapy 1. Reduce Lesion Count: Decrease the number of both non- inflammatory and inflammatory lesions to improve skin clarity. 2. Prevent Scarring: Minimize the risk of permanent scarring and long- term skin damage. 3. Reduce Inflammation and Bacterial Growth: Control the growth of Cutibacterium acnes bacteria and manage inflammation to promote healing. 4. Improve Quality of Life: Address the psychosocial impacts of acne, enhancing the patient’s self-esteem and overall well-being. Non-Pharmacologic Therapy Non-pharmacologic options aim to reduce acne severity and support overall skin health: 1. Skin Cleansing: Gentle, twice-daily washing with a mild, non- comedogenic cleanser. Avoid scrubbing as it can irritate skin. 2. Dietary Adjustments: Limiting high-glycemic-index foods and dairy (though evidence is mixed). Encouraging a balanced diet to support skin health. 3. Sun Protection: Daily use of non-comedogenic sunscreen to prevent post-inflammatory hyperpigmentation. 4. Avoiding Picking or Squeezing: Minimizes risk of scarring and inflammation. 5. Stress Management: Reducing stress levels, as it can worsen acne in some individuals.  Peritoneal Cavity The peritoneal cavity contains: Stomach Jejunum Ileum Appendix Large intestine (colon) Liver Gallbladder Spleen Retroperitoneal space contains: Duodenum Pancreas Kidneys  Intra-Abdominal Infections Intra-abdominal infections are infections contained within the peritoneum or retroperitoneal space. They are a common cause of hospital admission and the second leading cause of infectious mortality in ICU patients. These infections can occur in any intra-abdominal organ or space. Types of Intra-Abdominal Infections: Peritonitis Biliary tract infections Appendicitis Diverticulitis Infections following loss of bowel integrity due to trauma or surgery  Etiology Intra-abdominal infections are typically polymicrobial and can be caused by: Aerobic bacteria: Gram-positive aerobic cocci Gram-negative bacilli Anaerobic bacteria These infections can be severe, leading to sepsis and death.  Primary Peritonitis (Spontaneous Bacterial Peritonitis, SBP) Definition: Infection of the peritoneal space, often occurring in patients with liver disease (e.g., cirrhosis). Common Pathogens: Streptococci Enteric Gram-negative organisms (e.g., Proteus, E. coli, Klebsiella - PEK) Anaerobes (rarely) Treatment: Drug of choice: Ceftriaxone for 5-7 days Alternatives: Ampicillin, gentamicin, or a quinolone Prophylaxis: SMX/TMP, ofloxacin, and/or ciprofloxacin Clinical Manifestations The presentations of patients with intra-abdominal infections may vary depending on the site and type of infection. Common symptoms include: Abdominal pain with tenderness Rebound tenderness Fever Chills Nausea and vomiting Secondary Peritonitis Definition: Occurs secondary to an underlying condition. Common Pathogens: Streptococci Enteric Gram-negative organisms Anaerobes (e.g., Bacteroides fragilis) Causes: Peptic ulcer perforation Perforation of a GI organ Appendicitis Endometritis (e.g., secondary to intrauterine device) Bile peritonitis Surgery Pancreatitis Operative contamination Diverticulitis Intestinal neoplasms Secondary to peritoneal dialysis Abscesses are common and may require drainage and surgical intervention Cholecystitis Definition: Acute inflammation of the gallbladder due to an obstructive stone. Management: Usually managed surgically with cholecystectomy. Infection: Present in 50% of cases, with pathogens similar to those found in primary peritonitis Cholangitis Definition: Infection of the common bile duct, typically managed with bile decompression and antimicrobial therapy. Pathogen Coverage: Similar to secondary peritonitis, covering PEK, anaerobes, Streptococci ± Enterococci. Treatment of Secondary Peritonitis 1.Antibiotic Selection: 1. Must cover likely pathogens, including anaerobes. In some cases, a single antibiotic may suffice. If not, an additional antibiotic (usually metronidazole) is necessary. 2.Duration of Treatment: 1. Mild to moderate cases: 7 days 2. Severe cases: 14 days 3.Possible Regimens for Mild-Moderate Infections: 1. Cefoxitin 2. Ertapenem 3. Moxifloxacin 4. (Cefazolin, cefuroxime, or ceftriaxone) + metronidazole 5. (Ciprofloxacin or levofloxacin) + metronidazole 4.Agents for Treating Intra-Abdominal Infections: 1. Carbapenems 2. β-lactam/β-lactamase inhibitor combinations Severe Infections (ICU Patients) Coverage Required: PEK, Pseudomonas, anaerobes, Streptococci, and Enterococci. Possible Regimens: Carbapenem (except ertapenem) Piperacillin/Tazobactam (Cefepime or ceftazidime) + metronidazole (Ciprofloxacin or levofloxacin) + metronidazole (Aztreonam or aminoglycoside) + metronidazole Peptic Ulcer Disease (PUD)  Peptic ulcer disease (PUD) is a condition characterized by the presence of ulcers in the stomach (gastric ulcers) or the duodenum (duodenal ulcers) due to the disruption of the mucosal barrier and exposure to gastric acid and pepsin.  Etiology 1.Helicobacter pylori Infection 1. The most common cause globally. 2. Induces chronic inflammation and weakens the mucosal defense system. 2.Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) 1. Inhibit prostaglandin synthesis, which compromises mucosal protection. 2. Associated with both gastric and duodenal ulcers. 3.Stress-related Mucosal Damage (SRMD) 1. Common in critically ill patients. 2. Related to reduced mucosal blood flow and ischemia. 4.Other Factors 1. Excess gastric acid secretion (e.g., Zollinger-Ellison Syndrome). 2. Smoking and alcohol consumption. 3. Corticosteroid use (synergistic with NSAIDs). Epidemiology of Peptic Ulcer Disease 1.Prevalence: 1. PUD affects approximately 4.5 million people annually in the U.S. 2. The lifetime prevalence is about 10% in the general population. 2.Age and Gender: 1. Duodenal ulcers: More common in younger adults (30–50 years). 2. Gastric ulcers: Predominantly seen in older adults (>50 years). 3. Men have a higher prevalence of duodenal ulcers, while gastric ulcers are more evenly distributed between genders.  Pathophysiology 1.Normal Mucosal Protection: 1. A balance between aggressive factors (acid, pepsin) and defensive factors (mucus, bicarbonate, prostaglandins). 2.Ulcer Development: 1. An imbalance caused by increased aggressive factors or reduced defensive mechanisms. Diagnosis 1.Clinical Evaluation: 1. Detailed history of symptoms and risk factors (e.g., NSAID use). 2.Endoscopy: 1. Gold standard for diagnosis and visualization of ulcers. 2. Allows biopsy to test for H. pylori. 3.H. pylori Testing: 1. Urea breath test. 2. Stool antigen test. 3. Serology (less accurate). 4.Laboratory Tests: 1. Hemoglobin and hematocrit (to check for anemia). 2. Serum gastrin levels (if Zollinger-Ellison syndrome is suspected). Management Non-Pharmacologic Therapy 1.Lifestyle modifications: 1. Avoid NSAIDs, alcohol, smoking, and caffeine. 2. Smaller, frequent meals to reduce acid load. 2.Stress reduction and dietary adjustments. PPI Follow-Up and Monitoring 1.Assess symptom resolution after 4–8 weeks of therapy. 2.Confirm eradication of H. pylori with a urea breath test or stool antigen test 4 weeks after therapy completion. 3.Monitor for recurrence and manage complications promptly.  Complications 1.Bleeding Ulcers 1. Management: IV PPIs, endoscopic hemostasis, or surgery. 2.Perforation 1. Requires emergency surgical intervention. 3.Gastric Outlet Obstruction 1. Symptoms: Vomiting, weight loss. 2. Treatment: Endoscopic dilation or surgery Irritable Bowel Syndrome (IBS) Irritable Bowel Syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain or discomfort associated with altered bowel habits. It is a common condition with significant impacts on quality of life. Definition and Diagnostic Criteria Definition: A functional bowel disorder involving abdominal pain/discomfort and changes in stool consistency or frequency without identifiable structural abnormalities. Rome IV Criteria: Recurrent abdominal pain at least 1 day per week for the last 3 months, associated with two or more of the following: Related to defecation. Change in stool frequency. Change in stool form (appearance). Pathophysiology Altered Gut-Brain Axis: Dysregulation between the central nervous system (CNS) and the enteric nervous system (ENS). Visceral Hypersensitivity: Increased sensitivity to intestinal distention. Gut Dysmotility: Abnormalities in gastrointestinal muscle contractions. Microbiota Changes: Alterations in gut flora. Psychological Factors: Stress, anxiety, and depression can exacerbate symptoms. Classification IBS is classified based on predominant stool pattern: 1.IBS-C: Predominantly constipation. 2.IBS-D: Predominantly diarrhea. 3.IBS-M: Mixed constipation and diarrhea. 4.IBS-U: Unclassified. Clinical Presentation Common Symptoms: Abdominal pain (cramping or discomfort). Altered bowel habits (diarrhea, constipation, or both). Bloating and gas. Sensation of incomplete evacuation. Red Flags (may indicate other conditions): Weight loss, anemia, nocturnal symptoms, or rectal bleeding. Treatment Goals 1.Relieve symptoms (abdominal pain, bloating, and altered bowel habits). 2.Improve quality of life. 3.Minimize treatment side effects. Non-Pharmacologic Therapy 1.Dietary Modifications: 1. Low-FODMAP diet to reduce fermentable carbohydrates. 2. Avoid triggers like caffeine, alcohol, and fatty foods. 2.Lifestyle Changes: 1. Regular exercise. 2. Stress management techniques (e.g., yoga, mindfulness). 3.Psychological Interventions: 1. Cognitive-behavioral therapy (CBT). 2. Hypnotherapy. Role Pharmacists 1.Patient Counseling: 1. Educate on medication use and adherence. 2. Discuss non-pharmacologic options like diet changes. 2.Treatment Monitoring: 1. Assess efficacy and side effects of therapies. 2. Adjust treatment plans based on response. 3.Drug Interaction Checks: 1. Monitor for potential interactions, especially with antidepressants or polypharmacy.
