Psoriasis

Psoriasis on the scalp appears as red, itchy areas with silvery-white scales. You may notice flakes of dead skin in your hair or on your shoulders, especially after scratching your scalp. Don’t let scalp psoriasis interfere with your day-to-day life. Tackle the symptoms – include flaking, scaling and hair loss – with these effective treatment tips.


Of the approximately 7.5 million Americans that suffer from psoriasis, nearly half will experience scalp psoriasis, according to the National Psoriasis Foundation. A chronic conditions that’s characterized by intermittent flare-ups and alternating periods of remission, the effects of scalp psoriasis vary. For some, the condition can be mild, while others experience significant pain and discomfort.
Symptoms of scalp psoriasis   
Psoriasis is a disorder that affects skin at the cellular level, rapidly accelerating the production of cells and causing them to build up on the surface of the skin. Before long, silver, scale-like patches form, and are often accompanied by dryness, itchiness, inflammation and pain. While psoriasis can occur anywhere on the body, scalp psoriasis characterizes this condition when it occurs on the scalp, along the hairline, on the forehead or face and behind the ears. Scalp psoriasis is a form of plaque psoriasis and often, as the result of the buildup of dry, dead skin, flaking will occur or the patches will thicken to form scale-like plaques.
The severity of scalp psoriasis varies from person to person. Some will experience one or a few small patches while others may develop patches across the entire surface of the scalp. Some lesions cause little discomfort and can go unnoticed, while others may become painful, swollen, itchy, dry and/or inflamed. In rare cases, temporary hair loss may occur as the result of excessive scratching or harsh treatments.
Causes and risk factors
Unfortunately, scientists haven’t determined a specific cause for psoriasis, but genes are likely to play a role. According to Mayo Clinic, one in three individuals affected with psoriasis has a close relative that also suffers from the disease. Other factors can increase the risk of developing psoriasis and/or scalp psoriasis, including:
  • obesity
  • HIV
  • strep throat
  • smoking
  • stress
Many sufferers find that certain environmental factors can cause an outbreak or worsen an existing bout. Potential triggers include infection, minor skin irritations including scratches, scrapes or sunburn, cold temperatures, alcohol and certain medications. An important step in controlling scalp psoriasis is to identify the specific factors that may influence your condition and work to control or reduce them in your daily lifestyle.
Treatment options
Scalp psoriasis can easily be misdiagnosed as dandruff or seborrheic dermatitis, so it’s important to visit the doctor or dermatologist if you experience any unusual symptoms. He or she will likely do a small skin biopsy in order to properly diagnose the condition. Even though there isn’t a cure for scalp psoriasis, there are treatments and lifestyle remedies that can significantly improve symptoms. Treatment depends on the severity of the condition and most medications intended to treat scalp psoriasis contain similar ingredients as those that treat psoriasis on the body.

  • Mild to moderate: For a mild case of psoriasis, using specially formulated shampoos or topical creams that contain coal tar and non-coal tar is an effective treatment that hydrates skin while relieving itchiness and inflammation.

    • Product picks: Tarsum Shampoo/Gel from Summers is a therapeutic shampoo that features a special applicator cap to apply the product directly on psoriasis plaques.
    • For a moisturizing and healing cream, Mushatt's No. 9 Scalp Cream blends urea, sweet almond oil, sesame seed oil and salicylic acid to relieve itching, stop flaking and restore moisture for a healthier scalp.  

  • Severe cases: For severe cases of scalp psoriasis, your doctor may prescribe a topical treatment. Prescription medications including Anthralin, Calcipotriene (Dovonex), Tazarotene (Tazorac) or corticosteroids. These treatments vary in strength and each has different potential side effects.
  • In addition, your doctor may recommend biologics, which are oral drugs that work to improve immune function and may relieve the symptoms of scalp psoriasis. Talk to your doctor about which medication is right for you.
Phototherapy, or the use of UV light, is also incorporated into the treatment of scalp psoriasis, and at-home devices with comb-light attachments are available. This method can be less effective on the scalp, however, as hair creates a barrier between the light and the lesions, and some doctors caution about the risk factor of skin cancer. Talk with your doctor about the lifestyle factors that may influence your condition. Certain changes like reducing alcohol consumption, reducing stress and quitting smoking can help improve existing cases while preventing new outbreaks.
All forms of psoriasis, including scalp psoriasis, are often accompanied by mental and emotional challenges that only make dealing with the physical symptoms more difficult. Many find the visible plaques, scales and flaking to be unattractive, uncomfortable and embarrassing, causing stress, social anxiety and depression. When treating the physical symptoms of psoriasis, be sure to talk with your doctor about coping mechanisms to help deal with the mental stigma as well. Although there is no cure, with a diligent treatment plan, you can control the symptoms and prevent future outbreaks of scalp psoriasis for skin that looks and feels better.

Scalp Folliculities

if you’ve got stubborn red bumps on your scalp or hairline, you may be dealing with a case of scalp folliculitis, a condition caused by damaged hair follicles invaded by bacteria or fungus. While mild forms usually clear up on their own within two weeks, more severe cases can require prescription treatments. Learn the basics of how to address this condition and keep it from recurring.


How to identify scalp folliculitis
Folliculitis is the term for inflammation of the hair follicles and can occur anywhere that hair grows on your body. Since follicles are densest on the scalp, this is a common place for inflammation to develop. It typically shows up as itchy white or red pimples on the scalp or hairline.
Scalp folliculitis may resemble acne, but there is a difference between the two conditions: acne is a noninfectious form of folliculitis triggered by oil or bacteria clogging pores, while scalp folliculitis is usually due to infection with staphylococcus bacteria or a fungus that infects the damaged hair follicle.
Symptoms of scalp folliculitis vary according to the type of infection:
  • Superficial folliculitis, which affects the upper part of the hair follicle, is characterized by:
    • Red, inflamed skin
    • Clusters of tender or itchy red bumps that develop around hair follicles
    • Pustules that open and crust over
  • Deep folliculitis, which starts deeper in the skin and affects the entire hair follicle, includes the following symptoms:
    • A swollen bump or mass on the scalp
    • Pus-filled blisters
    • Possible scars once the infection is clear
A more severe form of folliculitis, known as “hot tub folliculitis,” results from coming into contact with bacteria that live in warm, wet areas – such as a hot tub that hasn’t been adequately chlorinated. Within several hours to two days of exposure to contaminated water, a rash of red, itchy round bumps will appear and may later develop into small pustules. This type of folliculitis can be painful and resistant to treatment.
Causes and risk factors
Scalp folliculitis can affect anyone, but some factors make people especially susceptible. Possible causes include:
  • Chronic skin conditions, such as eczema or dermatitis
  • Diseases that lower your resistance to infection, such as diabetes or HIV
  • Friction from shaving
  • Sweating
There are also forms of folliculitis that are non-infectious, such as those caused by oils and grease that clog up the hair follicles.
When folliculitis is severe, the inflammation is so intense that it can permanently destroy the hair follicles, leading to hair loss. Deep folliculitis can also result in scarring.
Home treatments
Mild folliculitis typically heals on its own within about two weeks, with the aid of over-the-counter antibiotic ointments if necessary. To treat scalp folliculitis at home, try the following options:
    • A warm, moist compress or washcloth made with white vinegar can relieve itching and ease discomfort.
    • Shampoo frequently using a medicated shampoo or one with tea tree oil – an essential oil that has effective germicidal and antibacterial properties, according to Dr. Andrew Weil.
    • For a natural approach, Dr. Weil recommends supplementing your diet with GLA (gamma-linolenic acid) and omega-3 fatty acids, which promote healthy growth of skin, hair and nails.
    • Apply an oatmeal lotion, or an over-the-counter hydrocortisone cream, to the affected area to ease itchy skin.
If the infection is more severe, you may need antibiotic or antifungal pills. See a doctor as soon as possible if: the infection spreads to other areas or keeps recurring; you develop a fever; or the infected area becomes red, swollen and painful.
Tips for prevention
Scalp folliculitis may not always be preventable, but there are ways to help stave off possible infection or keep it from recurring.
  • Bathe or shower daily, especially after exercise.
  • Use a clean towel every time you bathe, and don’t share towels with others.
  • Avoid scratching the bumps.
  • Don’t use oils on your skin and scalp, since they can trap bacteria in your hair follicles.
  • Only use hot tubs that have been properly disinfected.
Scalp folliculitis can be a minor inconvenience or a more painful condition – either way, it helps to educate yourself on the basics of causes, treatment and prevention so you can keep your scalp clear and healthy.

Ginjal II

Your blood carries oxygen and nutrients to your organs and tissues, and carries waste products to be flushed out of your body. Your kidneys control this process.
A Healthy Kidney Your Kidneys:
  • Control the balance of water in your body
  • Tell your body when to start and stop making oxygen-carrying red blood cells
  • Control how acidic your blood is
  • Filter your blood and pass the waste products on to your bladder as urine
  • Control your blood pressure
Your kidneys do three main jobs:
  1. Carry blood to and from the filters inside the kidney
  2. Filter blood
  3. Carry waste to your bladder

 

Symptoms of Kidney Disease

Kidney diseases can cause abnormalities in each kidney function, for example:
  • Abnormal control of the amount of water in your body causes accumulation of too much water resulting in swelling (edema)
  • Telling your body to stop making red blood cells causes too few red blood cells in the blood (anemia)
  • Abnormal control of how acidic your blood is causes too much acid in the blood (acidosis)
  • Reduced filtering of blood causes accumulation of waste products (such as urea) in blood (uremia)
  • Abnormal control of your blood pressure causes higher than normal blood pressure (hypertension)

The Nephron

NEPHROS is the Greek word for kidney. Your kidney doctor is called a NEPHROLOGIST because he treats kidney diseases.The tiny structures that do the work in your kidneys are called NEPHRONS. Each of your kidneys contains about one million nephrons. Each nephron has a small blood vessel that brings in unfiltered blood, a GLOMERULUS (glow-mare-Yule-us) that filters the blood, a tubule that caries away filtered waste materials in the urine, and a small blood vessel that returns filtered blood to the body.

Glomerular Disease

Diseases that injure GLOMERULI (plural for glomerulus) are called GLOMERULAR DISEASES.  Laboratory analysis of the urine from people who have glomerular disease often shows protein in the urine (proteinuria) and blood in the urine (hematuria).

How much cholesterol should I eat on a low cholesterol diet?

The risk for cardiovascular disease increases when blood cholesterol is high, and your cholesterol of 250 mg is in the high range; however, you need a fasting lipoprotein profile that measures LDL (the "bad cholesterol"), HDL (the "good cholesterol") and triglycerides before making therapeutic decisions. If your risk for heart disease is moderate or high, follow these diet recommendations:
  • limit dietary cholesterol to 200 mg a day
  • limit saturated fat to 7% of total calories (19 grams a day for you)
  • limit total fat to 25 – 35% of total calories (66 – 97 grams a day for you)
  • increase fiber to 25 - 38 grams per day (38 grams a day for you)
  • limit sodium to 2300 mg per day
  • exercise for at least 30 minutes a day and do weight-training twice a week

Mengolah daging babi dengan sehat


 Raw fresh Pork



 Daging merah seperti daging babi merupakan salah satu menu sumber protein yang sehat. Dalam setiap 100 gr daging babi mentah terkandung 18-32 gr protein (variatif, tergantung jenis bagian-bagian tubuhnya). Kadar proteinnya menandingi kandungan protein di setiap 100 gr sapi yaitu 36 gr. Namun, perlu diingat juga, tingkat kolesterol yang tinggi pada daging merah (khusunya daging babi), jadi jangan berlebihan mengkonsumsinya. 

Meski demikian,dalam 3 oz (28gr) sirloin roast pork (daging bagian punggung) hanya terkandung 3 gram lemak (66mg kolesterol) dan 116 kalori serta 23 gram protein sementara dalam sirloin roast sapi terkandung 19 gr protein. Kandungan lemak yang rendah ini membuat daging babi menjadi salah satu menu sumber protein yang sehat.  Selain itu, cara pengolahannya juga mempengaruhi kandungan lemak didalamnya. Agar tidak menambah kandungan lemak dan kalori pada olahan daging, jangan tambahkan minyak saat memasak.

Tips mengolah daging babi yang sehat
  1. Trim/pemangkasan
    Untuk daging babi yang sehat dan rendah lemak, buang semua serat lemak pada daging sebelum memasak. Gunakan pisau yang tajam,dan tarik ujung serat nya untuk menciptakan tegangangan dan memudahkan pengirisan. Jika daging telah bebas dari lemak, masak atau simpan dikulkas untuk diolah kemudian.

  1. Marinade/perendaman.
    Rendam daging sebelum dimasak agar lebih empuk dan juicy.  Jika air rendaman asam, serat daging akan rusak dan mengakibatkan kemampuan daging menyerap dan menahan air meningkat sehingga daging lebih lembab dan lembut nantinya. Agar lebih sehat, buat larutan rendamanmu sendiri yang bebas gula, minyak dan pengawet. Campurkan bumbu-bumbu seperti kecap,air lemon, cuka, dan zat asam lainnya. Lada hitam, cuka anggur merah, serbuk rosemary, bawang putih, jeruk lemon, dan campuran lainnya juga enak ditambahkan pada daging. Kreasikan saja. Rendam daging dalam plastik yang terkunci rapat. Lalu simpan di kulkas. Daging dapat direndam sampai lima hari. Semakin lama direndam,semakin kuat rasa bumbunya. Namun, hati-hati menjaga sterilitasnya , jangan sampai dagingnya busuk (Menurutku daging babi yang dijual di pasar tradisional kurang terjaga kebersihannya karena terpapar udara luar. Jadi, jangan terlalu lama merendamnya). Setelah direndam, daging dikeluarkan untuk diolah. Air rendamannya dapat dibuang atau diolah kembali menjadi saus pelengkap daging.
    http://healthyeating.sfgate.com/cook-healthy-pork-tenderloin-chops-3198.html

  1. Masak
    Daging yang telah direndam tadi dapat di grilling/broiling (dipanggang diatas kisi-kisi/lempengan besi), pan-searing (dipanggang di panci), braising, steaming, baking. Tentunya semuanya bebas minyak sehingga lebih sehat. Agar daging tidak lengket di panci, letakkan daging pada panci yang dingin lalu masak, selain itu hal tersebut juga membantu memanaskan cairan pada daging hingga terbentuk karamel. Jika ingin lebih sehat lagi, masukkan daging dalam kertas kalkir (parchment paper), sehingga betul-betul bebas minyak, sebelum dipanggang diatas panci atau dikukus. Panggang daging hingga kecoklatan(kecuali daging yang dikukus).

  1. Suhu memasak
    Agar sehat, masak daging hingga matang. Daging harus dimasak hingga bagian dalamnya mencapai suhu 145* Fahrenheit (62,77*celcius). Kalau daging babinya dari babi yang hidup liar/bebas bukan dikandang dengan makanan yang lebih variatif, suhu memasaknya harus lebih tinggi lagi, masak hingga bagian dalam daging bersuhu 160*fahrenheit (71.111celcius). Daging sisa dapat disimpan di kulkas selama 2 hari. Bisa juga dibekukan tetapi kualitasnya akan menurun dalam 4 bulan.
Selamat memasak..

cuap-cuap:
 Daging merah memiliki kualitas protein yang baik dan beragam dengan nutrisi yang tinggi dibandingkan daging ayam. Namun, karena tingkat kolesterol yang tinggi jangan berlebihan mengkonsumsinya.

Telur juga memiliki tingkat kolesterol yang tinggi (160 mg/telur). Jadi, gak sehat dikonsumsi berlebih, maksimal 2 telur/hari. Batas konsumsi kolesterol 200mg-250mg perhari.

 Ikan sangat sehat, tapi tergantung pengolahannya juga.

 Daging ayam tergolong  rendah kolesterol dan tinggi protein dibandingkan daging merah, namun kualitas protein dan nutrisinya lebih rendah dari daging merah.

Kolesterol dibutuhkan dalam pembentukan hormon, vitamin D, melindungi sel dan dibutuhkan dalam pencernaan. Namun, tingkat kolesterol yang tinggi dapat menyebabkan gagal jantung. Darah yang begitu kental dan lengket juga dapa menyebabkan tekanan darah tinggi dan stroke. Selain itu, hati juga memproduksi kolesterol sehingga kita hanya membutuhkan sedikit saja tambahan kolesterol dari makanan.

Jadi kalau kamu pecinta daging merah,  jangan lupa untuk mengkonsumsi cukup sayur dan buah. alpukat, kiwi dan buah 2 lainnya sangat bagus dikonsumsi sebagai counter attack kolesterol.
kandungan kolesterol pada setiap 3 oz daging (28 gr):

Daging babi
50mg-105mg
Daging sapi
90 mg
Salmon
42 mg
Ayam
72 mg
