🚨The management of Ulcerative Colitis Mild to Moderate UC: 5-ASA (Mesalamine): First-line for induction and maintenance (oral and/or rectal forms). Topical corticosteroids: For distal colitis ( hydrocortisone enema). Oral corticosteroids: If unresponsive to 5-ASA. Moderate to Severe UC: Systemic corticosteroids: (e.g., prednisone). Immunomodulators: Azathioprine, 6-mercaptopurine. Biologics: Anti-TNF: infliximab, adalimumab. Anti-integrins: vedolizumab. JAK inhibitors: tofacitinib (for moderate-severe UC). Surgery: Colectomy is curative (indicated in toxic megacolon, refractory disease, or dysplasia).

شرح مبسط عن ulcerative colitis Ulcerative colitis causes and symptoms (UC): Ulcerative colitis is an inflammatory bowel disease (IBD) that causes inflammation& ulcers in your digestive tract. Ulcerative colitis affects the inner most lining of your large intestine- colon & rectum. UC develops when the lining of the colon and rectum become inflamed. This creates ulcers on the colon’s lining, starting in the rectum and spreading upward, and can result in frequent bowel movements and discharge of mucus and pus. 🔸Causes and risk factors: 🔹Age: Most people get diagnosed between 15 and 30 years old or when they’re older than 60 . 🔹Genetics: You’re more likely to develop UC if a first-degree relative (parent, sibling or child) has it. 🔹Self-medicating/discontinuing antibiotic courses 🔹Immune system reaction: The body might respond to a viral/bacterial infection in a way that causes the inflammation. Once the infection resolves,the immune system continues to respond,leading to ongoing inflammation. 🔸Common symptoms include: 🔹Abdominal pain 🔹Increased abdominal sounds 🔹bloody stools 🔹diarrhea 🔹Rectal pain 🔹Weight loss 🔹Malnutrition/Malabsorption 🔹Joint pain/swelling 🔹Extreme constipation 🔹Fever 🔹Malnutrition/Malabsorption 🔹Constant mouth sores 🔹Fatigue 🔹Anemia 🔹Skin problems 🔹Liver issues 🔹Inflammation

Correct answer: Pitting of the nails refers to the presence of small depressions or indentations on the nail surface, resembling pin pricks. It occurs due to defective keratinization of the proximal nail matrix, where the nail is formed. Nail pitting is a clinical sign, not a disease itself, and is often associated with various dermatological and systemic conditions. The most common cause is psoriasis, where up to 50% of patients exhibit nail involvement. In psoriasis, pitting is typically irregular, coarse, and scattered. It may be accompanied by other nail changes like onycholysis, subungual hyperkeratosis, or discoloration. Pitting also appears in alopecia areata, often with finer, more uniform pits. Other causes include eczema, lichen planus, and Reiter’s syndrome. Rarely, it can be seen in systemic diseases like sarcoidosis or thyroid disorders. Diagnosis is usually clinical, based on nail examination and history. Dermoscopy may help visualize subtle pits. In uncertain cases, nail biopsy can be done. Management focuses on treating the underlying condition. In psoriatic nail disease, topical corticosteroids, vitamin D analogs, or systemic therapy may help. Severe cases might benefit from biologic agents. Nail care and avoiding trauma are essential to prevent worsening.

Esophageal Cancer can develop silently but early symptoms matter. ⚠️ Chronic acid reflux or heartburn ⚠️ Difficulty swallowing ⚠️ Unexplained weight loss ⚠️ Persistent cough or hoarseness ⚠️ Vomiting ⚠️ Bleeding in esophagus If you have symptoms, don’t ignore them.

موضوع لازم يكون علي تليفونك لازم تكون واعي وفاهم لكل كلمة في المنشور هيفرق كتير New Guidelines for Eosinophilic Esophagitis (EoE) - Released January 2025! 1/ Diagnosing EoE: Clinical symptoms: dysphagia, food impaction . 🔬≥15 eosinophils/HPF on esophageal biopsy. No rule out other causes of eosinophilia. Precision is key of diagnosis 2/ Systematic Assessment Symptoms + atopic history. Endoscopy: Use EREFS to describe findings (Edema, Rings, Exudates, Furrows, Strictures). Biopsies: Take ≥6 samples from multiple locations. 3/ Treatment Options drugs vs foods Shared decision-making is key! Patients choose between: a) Medicine: PPIs, steroids, biologics. b) Diet: Empirical elimination tailored to lifestyle. 4/ PPIs: No longer diagnostic, but a treatment option. High-dose (8–12 weeks) → Reassess via endoscopy! Still a cornerstone in managing inflammation. 5/ Dietary Therapy: - food elimination (dairy, wheat, egg, soy, nuts, seafood) Less restrictive: Dairy-only (~40% response) .Dairy + wheat (~similar to 6-food). Adapt based on needs. Flexibility matters 6/ Steroids (Topical): 1st-line therapy for most cases ✅FDA-approved: Budesonide suspension: 2 mg BID x 12 wks. Budesonide tabs: 1 mg BID x 6–12 wks. Off-label: Fluticasone (swallowed, not inhaled). 7/ Biologics: Dupilumab: Blocks IL-4/IL-13 signaling. For refractory EoE or allergic comorbidities. Approved for ages ≥1. Other biologics still experimental. 8/ Esophageal Dilation: For strictures or stenosis. Safe if done gradually. Goal: Diameter of 16–18 mm, often in multiple sessions. 9/ Long-Term Management: Chronic, relapsing disease → most treatments are long-term Regular monitoring with endoscopy + biopsies. Symptom relief not equal inflammation resolution 10/ Pediatric Highlights Infants: Poor growth, feeding issues. Kids: Vomiting abdominal pain dysphagia Treatments similar to adults, but tailored for growth and development . 11/ Key Updates: 🆕 PPIs now therapeutic, not diagnostic. ✅FDA-approved budesonide simplifies treatment. 🌈Dupilumab = major step for refractory cases. 🔬Biopsies remain critical, even with symptom improvement.

المختصر المفيد 𝐅𝐥𝐮𝐢𝐝 𝐓𝐡𝐞𝐫𝐚𝐩𝐲 - 𝐊𝐞𝐲 𝐏𝐨𝐢𝐧𝐭𝐬 . ➡️ Patients with diarrhea requiring IV fluid resuscitation should receive LR ( Lactated Ringer ) as it better corrects the hyperchloremic metabolic acidosis they can develop. ➡️ Patients with GI losses from profuse vomiting, gastric outlet obstruction, and nasogastric suctioning develop a hypochloremic metabolic alkalosis. In these patients, the best choice is normal saline as it contains a higher concentration of chloride. ➡️ Rhabdomyolysis requires early and aggressive fluid resuscitation to prevent AKI and increase urinary potassium excretion. The initial treatment is NS (normal saline) at a rate of 1 to 2 L/h.4/ ➡️ DKA or HHS requires careful electrolyte and fluid replacement; the recommended initial resuscitation fluid is NS at 1 to 1.5 L given during the first hour. Subsequent fluids should be either 0.45% NS or LR to prevent hyperchloremic metabolic acidosis. ➡️ Patients with superficial deep and full-thickness burns >30% of total body surface area should receive fluid resuscitation with LR. ➡️ With few exceptions, there appears to be no proven clinical superiority to using colloids over crystalloids.

The commonest arrhythmia develops in patients with alcoholic cardiomyopathy is → Atrial Fibrillation.

🛑Management hemodynamic in patient with Acute renal impairment 🉐Do not think that hypovolemia is the cause of AKI ✅1) If AKI develop suddenly in ICU patient without clear history of fluid/blood loss ✅2) If patient has AKI with normal/high pulse pressure         .............................. ✅Fluid should be given until hypovolemia is corrected and NOT until AKI is resolved ✅Do not add maintenance fluid in patients with oliguria except after increase in urine output ✅Do not give fluid without looking to the status of the lung #salah

Treatment of brucella in pregnancy.. Treating brucellosis in pregnancy requires a careful approach to balance the safety of the fetus and the effectiveness of therapy. Brucellosis during pregnancy can lead to complications such as miscarriage, preterm labor, or congenital infection. Here are the key points for treatment: Antibiotic Therapy 1. Preferred Regimen: Rifampin: 600-900 mg once daily Trimethoprim-Sulfamethoxazole (TMP-SMX): (160/800 mg) twice daily This combination is generally considered safe and effective for pregnant women. 2. Avoided Antibiotics: Doxycycline and Tetracyclines: These are contraindicated in pregnancy due to their effects on fetal bone and teeth development. Streptomycin and Gentamicin: Aminoglycosides are typically avoided because of the risk of fetal ototoxicity. The duration of treatment for brucellosis during pregnancy is typically 6 weeks, depending on the severity of the infection and clinical response. This extended duration is essential to reduce the risk of relapse. Key Considerations: 1. Monitor Symptoms: If symptoms persist or relapse occurs, treatment may need to be prolonged. 2. Combination Therapy: Using two antibiotics, such as rifampin and trimethoprim-sulfamethoxazole (TMP-SMX), for the full course is crucial for effectiveness and to avoid resistance. 3. Post-Treatment Monitoring: Regular follow-up is needed after completing therapy to ensure complete resolution of the infection Monitoring Regular Follow-up: Monitor both the mother and fetus for complications. Serological Testing: To assess treatment response. Prevention Avoid unpasteurized dairy products and contact with infected animals to minimize the risk of brucellosis. Note: Always consult an obstetrician and infectious disease specialist for individualized treatment plans.

Hypokalemia is generally defined as a serum potassium level of less than 3.5 mEq/L (3.5 mmol/L). Moderate hypokalemia is a serum level of 2.5-3.0 mEq/L, and severe hypokalemia is a level of less than 2.5 mEq/L For every 1 mEq/L decrease in serum potassium, the potassium deficit is approximately 200-400 mEq. Patients with a potassium level of 2.5-3.5 mEq/L may need only oral potassium replacement If the potassium level is less than 2.5 mEq/L, intravenous (IV) potassium should be given, with close followup, continuous ECG monitoring, and serial potassium levels The serum potassium level is difficult to replenish if the serum magnesium level is also low Surgical treatment..renal artery stenosis,adrnal adenoma ,villus adenoma.
