​Kembara Xtra - Medicine - Raynaud Phenomenon

​Kembara Xtra - Medicine - Raynaud Phenomenon 
Cold, emotional stress, or blunt trauma-induced idiopathic intermittent episodes of vasoconstriction of digital arteries, precapillary arterioles, and cutaneous arteriovenous shunts - The main physical symptom is a triphasic color shift in the fingers (rarely the toes or nipples).
The skin initially appears white due to excessive pallor, then turns blue due to cyanosis, and eventually turns red as a result of warming and vasodilation.
Rarely are thumbs involved.
- Associated symptoms include paresthesias, throbbing, and swelling.
- Elementary
80 percent of patients have a main illness.
Episodes are nonprogressive and bilateral.
If no underlying connective tissue illness manifests after 2 years of symptoms, the diagnosis is considered to be confirmed.
Asymmetric and progressive
Vascular spasms become more severe and common with time. There are very few ulcerations, no gangrene develops, and 13% advance to fingertip alterations from ischemia and atrophy of the digital fat pad.
 Usually linked to an underlying connective tissue condition Hematologic, lymphatic, immunologic, musculoskeletal, dermatologic, and exocrine system(s) are affected. 

pregnant women's issues
Breast pain in lactating mothers may be a symptom of the Raynaud phenomenon.
Mastitis and the Raynaud phenomenon can be distinguished by a positive breast milk bacterial culture.
Aspects of Geriatrics
After age 40, Raynaud's first symptoms suggest a connective tissue illness may be present.
Systemic lupus erythematosus (SLE) and scleroderma pediatric considerations

Primary epidemiology incidence - Predominant age: 14 years; 1/4 start older than 40 years - Predominant sex: female > male (4:1)
Secondary - Predominant age: over 40 - Predominant sex: neither gender is preferred
Prevalence
(Based on clinical history) Primary: 3-12% of men; 6-20% of women; Secondary: 1% of the population

Pathophysiology and Etiology 
Unknown. Vasodilation and vasoconstriction are imbalanced as a result of vascular control mechanism dysregulation. 5-HT2 serotonin receptors may be involved in secondary Raynaud syndrome, which is characterized by decreased endothelin-dependent vasodilation activity and increased vasoconstriction in peripheral arteries. Ischemic pathology is influenced by changes in platelet and blood viscosity in secondary illness.
Genetics
Research points to a prevalent inheritance pattern. A first-degree relative with Raynaud phenomenon affects about one-fourth of people with the primary ailment.

End-stage renal disease with hemodialysis may increase risk if a steal phenomena occurs in conjunction with the arterial-venous shunt. Risk Factors: Existing autoimmune or connective tissue illness.
 Primary and secondary conditions linked to high homocysteine levels Smoking may exacerbate symptoms but is not linked to an increased risk of Raynaud's phenomenon.

Prevention 
Avoid being exposed to the cold. Quit smoking.
The usage of vibratory tools and the Raynaud phenomenon have not been linked.
Anxiety and stress can start an attack.
CONDITIONS OFTEN Associated with
Additional Raynaud
Sjögren syndrome, polymyositis, SLE, occlusive vascular disease, and scleroderma >> Cryoglobulinemia

Diagnosis 

Primary - Symmetric attacks affecting the fingers - Family history of connective tissue condition - Absence of tissue necrosis, ulceration, or gangrene - If secondary disease has not manifested after two years of symptoms, it is improbable.
Secondary - Onset usually after age 40 - Asymmetric bouts more severe and intense
- Myalgias, arthritis, fever, dry mouth, dry eyes, rash, or cardiopulmonary symptoms - Exposure to hazardous substances - A history of pharmaceutical usage or recreational drug use - Repeated trauma

clinical assessment 
Fingertip cyanosis (blueness) after exposure to cold, followed by redness and soreness after warming  Ischemic attacks are characterized by demarcated or cyanotic skin that is restricted to the digits. These attacks often begin on one digit and spread symmetrically to the remaining fingers on both hands. Usually, the thumb is unharmed.
 Rarely affects other tissues (such as the tongue). Beau lines are transverse linear depressions in the nail plate that appear on most or all fingernails following exposure to cold or any other injury that prevents the normal growth of the nail. Livedo reticularis: benign mottling of the arms and legs' skin that goes away with warmth Primary - Normal physical examination - Nail bed capillaries are normal At the base of the fingernail, apply 1 drop of immersion oil grade B to the skin and use a portable ophthalmoscope with a diopter range of 10 to 40 to see the capillaries.
Secondary - Arthritis, abnormal lung results, and skin changes point to connective tissue disease.
- Ischemic skin lesions: finger pads that ulcerate (severe, protracted cases may require autoamputation). - Distortion of the capillaries in the nail bed, including enormous loops, avascular regions, and increased tortuosity - Abnormal Allen test (have the patient open and close their hand repeatedly before clenching it firmly). The patient opens the hand to demonstrate the restoration of color as a gauge of circulation while the ulnar and radial arteries are successively blocked.)

Differential Diagnosis: Men are more likely to develop thromboangiitis obliterans (Buerger disease), which is caused by smoking RA is a kind of arthritis.
Raynaud phenomenon comes first in progressive systemic sclerosis (scleroderma) symptoms.
SLE, thoracic outlet syndrome, hypothyroidism, carpal tunnel syndrome
Calcinosis cutis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasias are all symptoms of the CREST syndrome. Acrocyanosis, Waldenström macroglobulinemia, polycythemia, cryoglobulinemia
Occupational (particularly from vibrating instruments, exposure to polyvinyl chloride, masonry work) and drug-induced (e.g., amphetamines, clonidine, ergotamine, methysergide, bleomycin, vinblastine, cisplatin, cyclosporine)

Laboratory Results 
Provocative tests, including immersion in icy water, are pointless. Primary - Antinuclear antibody: negative
- Normal ESR
Tests for secondary reasons, such as the CBC and ESR, are secondary.
- For connective tissue illness, a positive autoantibody has a 30% poor positive predictive value.
- Autoantigen-specific antibodies, such as those found in scleroderma patients with anticentromere or anti-topoisomerase antibodies.
The gold standard (200 times magnification) is videocapillaroscopy.


Tests in the Future & Special Considerations

Regular evaluations for a connective tissue condition Diagnostic Techniques/Other
Exam results and medical history help make the diagnosis.


Raynaud Condition Score is used by management to evaluate.

General Actions 

During attacks, rotate the arms in a windmill pattern, immerse the hands under warm water, or in a warm body fold to relieve symptoms. Dress warmly, use gloves, and avoid chilly temperatures.
 Stopping smoking
Avoid -blockers, amphetamines, ergot alkaloids, OTC drugs containing pseudoephedrine, sumatriptan, and -blockers. Temperature-related biofeedback may help patients raise their hand temperatures. Follow-up after one year is comparable to control.

First Line of Medicine
CCBs, or calcium channel blockers. The most extensively studied and utilized drug is nifedipine.
Nifedipine: 30 to 180 mg/day (sustained-release version); treatment throughout the winter months is helpful, with up to 75% of patients reporting improvement.
 Suitable for breastfeeding
 Contraindications: medication allergy, pregnancy, and heart failure
 Caution: may result in headache, lightheadedness, dizziness, edema, or hypotension Significant potential interactions: Raises serum digoxin levels Second Line
Nicardipine and amlodipine (5 to 10 mg/day) may be less harmful alternatives while still being effective.
There is no evidence to recommend switching to CCB if the first medication is ineffective.
Losartan and fluoxetine are beneficial, according to small trials.
Sildenafil and vardenafil, phosphodiesterase type-5 inhibitors, may lessen symptoms without enhancing blood flow.
Parenteral iloprost, a prostacyclin, has improved ulcerations with severe Raynaud phenomenon when CCBs failed (0.5 ng/kg/min over 6 hours). Prostacyclin taken orally has not been effective.
Patches containing nitroglycerin may be useful, but their usage is constrained by the prevalence of severe headache. Gel containing nitroglycerin has showed potential as a topical treatment.
Topical sildenafil cream may help individuals with secondary Raynaud phenomenon by enhancing digital arterial blood flow.
ACE inhibitors are no longer advised; prazosin (1–2 mg TID) is the only well-studied 1-adrenergic receptor blocker with a small effect; side effects may outweigh any benefits.

Referral 

Consider consulting a rheumatologist for an assessment and therapy if an underlying condition is detected.

Furthermore Treated 

Aspirin Digital or wrist block with lidocaine or bupivacaine (without epinephrine) for pain control Short-term anticoagulation with heparin if persistent critical ischemia, evidence of large-artery occlusive disease, or both Aspirin Digital or wrist block with lidocaine or bupivacaine (without epinephrine) for pain control Aspirin 


Surgical Techniques 

Surgery is rarely used to treat Raynaud's syndrome. The cervical sympathectomy's effects are short-lived; symptoms usually reappear in one to two years. A novel method called digital fat grafting has alleviated symptomatology and indications of significantly enhanced perfusion in a number of patients.


Alternative Therapies 

Ginkgo biloba has an unknown benefit Fish oil supplements may lengthen the time it takes for symptoms to appear after exposure to a cold; however, this has not been established in controlled studies.
In vitamin D-deficient Raynaud phenomenon patients, vitamin D supplementation improved self-reported symptoms.
In one trial, evening primrose oil lessened the severity of attacks.
Oral arginine is equally effective to a placebo.
It has been discovered that acupuncture and accupressure are effective at reducing symptoms, although studies have been small and the evidence is not statistically significant.
Biofeedback is probably not useful.

Take Action 

Keep away from the cold; reevaluate for secondary reasons.
patient observation
Treat infections quickly and take care of fingertip ulcers.
no special dietary requirements


Lifestyle adjustments
​Quitting smoking
Avoid triggers, such as cold, vibration, and trauma.
Wear gloves and thick clothing.
 When experiencing vasospasm, hold warm hands.

Prognosis: 2/3 of attacks resolve spontaneously, with attacks lasting anywhere from a few minutes to a few hours.
A secondary condition, usually a connective tissue disease, develops in 13% of people with Raynaud's disease.


Secondary complications include gangrene and finger autoamputation. Primary complications are extremely infrequent.
