First Aid and Management of Burns

Burns can be caused by heat, electricity, or chemicals. Immediate first aid involves removing the person from the source of the burn and irrigating the affected area with cool water. The extent of the burn can be assessed using Wallace’s Rule of Nines or the Lund and Browder chart. The depth of the burn can be determined by its appearance, with full-thickness burns being the most severe. Referral to secondary care is necessary for deep dermal and full-thickness burns, as well as burns involving certain areas of the body or suspicion of non-accidental injury.

Severe burns can lead to tissue loss, fluid loss, and a catabolic response. Intravenous fluids and analgesia are necessary for resuscitation and pain relief. Smoke inhalation can result in airway edema, and early intubation may be necessary. Circumferential burns may require escharotomy to relieve compartment syndrome and improve ventilation. Conservative management is appropriate for superficial burns, while more complex burns may require excision and skin grafting. There is no evidence to support the use of antimicrobial prophylaxis or topical antibiotics in burn patients.

Characteristics of Melanoma: The ABCDE Mnemonic

Melanoma is a type of skin cancer that can be deadly if not detected and treated early. To help identify potential melanomas, dermatologists use the ABCDE mnemonic. Each letter represents a characteristic that may indicate the presence of melanoma.

A stands for asymmetry. If one half of a mole or lesion doesn’t match the other half, it may be a sign of melanoma. B is for border irregularity. Melanomas often have uneven or jagged edges. C represents color variegation. Melanomas may have multiple colors or shades within the same lesion. D is for diameter. Melanomas are typically larger than a pencil eraser, but any mole or lesion that is 6mm or more in diameter should be examined by a dermatologist. Finally, E stands for evolution. Any changes in size, shape, or color of a mole or lesion should be monitored closely.

By remembering the ABCDE mnemonic, individuals can be more aware of the characteristics of melanoma and seek medical attention if they notice any concerning changes in their skin.

The sudden appearance of linear, well-defined skin lesions with a lack of concern or emotional response, known as ‘la belle indifference’, strongly suggests dermatitis artefacta or factitious dermatitis. This rare condition involves self-inflicted skin damage, and patients often deny their involvement. Treatment requires a collaborative approach between dermatologists and psychiatrists, with a focus on building a positive relationship with the patient. Other conditions such as dermatitis herpetiformis, lichen planus, and neurotic excoriations have different clinical presentations and are not consistent with the scenario described.

Understanding Dermatitis Artefacta

Dermatitis artefacta is a rare condition that affects individuals of any age, but is more common in females. It is characterised by self-inflicted skin lesions that patients typically deny are self-induced. The condition is strongly associated with personality disorder, dissociative disorders, and eating disorders, with a prevalence of up to 33% in patients with bulimia or anorexia.

Patients with dermatitis artefacta present with well-demarcated linear or geometric lesions that appear suddenly and do not evolve over time. The lesions may be caused by scratching with fingernails or other objects, burning skin with cigarettes, or chemical exposure. Commonly affected areas include the face and dorsum of the hands. Despite the severity of the skin lesions, patients may display a nonchalant attitude, known as la belle indifference.

Diagnosis of dermatitis artefacta is based on clinical history and exclusion of other dermatological conditions. Biopsy of skin lesions is not routine but may be helpful to exclude other conditions. Psychiatric assessment may be necessary. Differential diagnosis includes other dermatological conditions and factitious disorders such as Munchausen syndrome and malingering.

Management of dermatitis artefacta involves a multidisciplinary approach with dermatologists, psychologists, and psychiatrists. Direct confrontation is unhelpful and may discourage patients from seeking medical help. Treatment includes providing occlusive dressing, topical antibiotics, and bland emollients. Selective serotonin reuptake inhibitors and cognitive behavioural therapy may be helpful, although evidence is limited.

In summary, dermatitis artefacta is a rare condition that requires a multidisciplinary approach for management. Understanding the clinical features, risk factors, and differential diagnosis is crucial for accurate diagnosis and appropriate treatment.

During pregnancy, acne is a common issue and many typical treatments are not appropriate. However, it is safe to use topical antibiotics for managing acne during pregnancy. It is recommended to prescribe a combination of topical antibiotics and benzoyl peroxide. On the other hand, topical retinoids should not be used during pregnancy. If topical treatments are not effective, oral erythromycin can be considered as an option.

Acne vulgaris is a common skin condition that usually affects teenagers and is characterized by the obstruction of hair follicles with keratin plugs, resulting in comedones, inflammation, and pustules. The severity of acne can be classified as mild, moderate, or severe, depending on the number and type of lesions present. Treatment for acne typically involves a step-up approach, starting with single topical therapy and progressing to combination therapy or oral antibiotics if necessary. Tetracyclines are commonly used but should be avoided in certain populations, and a topical retinoid or benzoyl peroxide should always be co-prescribed to reduce the risk of antibiotic resistance. Combined oral contraceptives can also be used in women, and oral isotretinoin is reserved for severe cases under specialist supervision. Dietary modification has no role in the management of acne.

Effective Treatments for Fungal Nail Infections

According to clinical evidence, the most effective treatments for fungal nail infections are oral terbinafine and oral itraconazole. Topical treatments such as amorolfine and terbinafine have no good quality evidence to support their use, although topical ciclopirox may be effective. While various topical agents may be recommended for mild disease, oral treatment is usually required for a cure.

It is important to note that topical treatments should only be considered if less than eighty percent of the nail is involved, or there are two or less nails affected. In diabetics or those with vascular disease, fungal nail infections can be a portal for bacterial infection and subsequent cellulitis, making effective treatment crucial.

Regardless of whether a person has had Chickenpox or shingles previously, Zostavax should still be administered.

Varicella-Zoster Vaccination: Protection Against Chickenpox and Shingles

Varicella-zoster is a herpesvirus that causes Chickenpox and shingles. There are two types of vaccines available to protect against these infections. The first type is a live attenuated vaccine that prevents primary varicella infection or Chickenpox. This vaccine is recommended for healthcare workers who are not immune to VZV and for individuals who are in close contact with immunocompromised patients.

The second type of vaccine is designed to reduce the incidence of herpes zoster or shingles caused by reactivation of VZV. This live-attenuated vaccine is given subcutaneously and is offered to patients aged 70-79 years. The vaccine is also available as a catch-up campaign for those who missed out on their vaccinations in the previous two years of the program. However, the shingles vaccine is not available on the NHS to anyone aged 80 and over because it seems to be less effective in this age group.

The main contraindication for both vaccines is immunosuppression. Side effects of the vaccines include injection site reactions, and less than 1 in 10,000 individuals may develop Chickenpox. It is important to note that vaccination is the most effective way to prevent varicella-zoster infections and their complications.

Kawasaki Disease Treatment and Follow-Up

Patients diagnosed with Kawasaki disease typically require hospitalization for treatment with intravenous immunoglobulin and to monitor for potential myocardial events. Due to the risk of cardiac complications, follow-up echocardiograms are necessary to detect any coronary artery aneurysms. It is important to note that Kawasaki disease is not a notifiable disease.

Understanding the Dermatology Life Quality Index (DLQI)

The Dermatology Life Quality Index (DLQI) is a commonly used tool to evaluate the impact of chronic skin conditions on a patient’s quality of life. It consists of 10 questions, each scored out of 3, with a maximum score of 30. The higher the score, the more significant the impact on the patient’s quality of life. The DLQI covers six areas, including symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment.

The DLQI questions are designed to assess the level of discomfort, embarrassment, and interference with daily activities caused by the skin condition. Patients are asked to rate the severity of symptoms such as itchiness, soreness, and pain, as well as the impact on social and leisure activities, work or study, and personal relationships. The DLQI also evaluates the impact of treatment on the patient’s life.

Interpreting the DLQI scores is straightforward. A score of 0-1 indicates no effect on the patient’s life, while a score of 2-5 suggests a small impact. A score of 6-10 indicates a moderate effect, while a score of 11-20 suggests a very large impact. A score of 21-30 indicates an extremely large impact on the patient’s life.

In summary, the DLQI is a quick and easy tool to assess the impact of chronic skin conditions on a patient’s quality of life. It provides valuable information to healthcare professionals to tailor treatment plans and improve patient outcomes.

Reiter’s syndrome is characterized by the presence of waxy yellow papules on the palms and soles, a condition known as keratoderma blenorrhagica.

Skin Disorders Associated with Systemic Lupus Erythematosus (SLE)

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect various organs and tissues in the body, including the skin. Skin manifestations of SLE include a photosensitive butterfly rash, discoid lupus, alopecia, and livedo reticularis, which is a net-like rash. The butterfly rash is a red, flat or raised rash that appears on the cheeks and bridge of the nose, often sparing the nasolabial folds. Discoid lupus is a chronic, scarring skin condition that can cause red, raised patches or plaques on the face, scalp, and other areas of the body. Alopecia is hair loss that can occur on the scalp, eyebrows, and other areas of the body. Livedo reticularis is a mottled, purplish discoloration of the skin that can occur on the arms, legs, and trunk.

The skin manifestations of SLE can vary in severity and may come and go over time. They can also be a sign of more serious internal organ involvement. Treatment for skin manifestations of SLE may include topical or oral medications, such as corticosteroids, antimalarials, and immunosuppressants, as well as sun protection measures.

Common Skin Conditions During Pregnancy

Pregnancy can bring about various changes in a woman’s body, including changes in the skin. Here are some common skin conditions that may occur during pregnancy:

1. Pemphigoid Gestationis (Herpes Gestationis)
This rare bullous disorder is caused by circulating immunoglobulin G (IgG) autoantibodies similar to those found in bullous pemphigoid. It usually appears in the second trimester but can occur at any stage and may even worsen postpartum. Symptoms include extremely itchy urticarial papules and blisters on the abdomen and trunk, which may become generalized.

2. Polymorphic Eruption of Pregnancy (Pruritic Urticarial Papules and Plaques of Pregnancy)
This benign dermatosis typically arises late in the third trimester of a first pregnancy or in multiple pregnancies. Itchy erythematous papules and plaques first appear on abdominal striae and then spread to the trunk and proximal limbs. The umbilicus is usually spared.

3. Pregnancy Prurigo
Prurigo of pregnancy presents as scattered, itchy/scratched papules at any stage of pregnancy. It is often mistaken for scabies but doesn’t respond to antiscabetic agents. Emollients and topical corticosteroids may help.

4. Pruritus (Cholestatic) of Pregnancy
Cholestatic pruritis appears as unexplained pruritus during the second and third trimesters, with raised blood levels of bile acids and/or liver enzymes. It typically starts in the soles of the feet and palms of the hands and progresses to the trunk and face.

5. Scabies
Although rare, bullous lesions have been reported in scabies. However, this is not the most common cause of this presentation.

It is important to consult a healthcare provider if any skin changes or symptoms occur during pregnancy.

A patient with severe acne, including scarring, hyperpigmentation, and widespread pustules, should be referred to a dermatologist for specialized treatment. In this case, the patient has nodules, pustules, and scarring, indicating the need for consideration of oral isotretinoin. A trial of low-strength topical benzoyl peroxide would not be appropriate for severe and widespread acne, but may be suitable for mild to moderate cases. Same-day hospital admission is unnecessary for a patient with normal observations and no other health concerns. A review in 2 months is not appropriate for severe acne, which should be managed with topical therapies, oral antibiotics, or referral to a dermatologist. Topical antibiotics are also not recommended for severe and widespread acne, and a dermatology referral is necessary for this patient with lesions on the face, neck, and trunk.

Acne vulgaris is a common skin condition that usually affects teenagers and is characterized by the obstruction of hair follicles with keratin plugs, resulting in comedones, inflammation, and pustules. The severity of acne can be classified as mild, moderate, or severe, depending on the number and type of lesions present. Treatment for acne typically involves a step-up approach, starting with single topical therapy and progressing to combination therapy or oral antibiotics if necessary. Tetracyclines are commonly used but should be avoided in certain populations, and a topical retinoid or benzoyl peroxide should always be co-prescribed to reduce the risk of antibiotic resistance. Combined oral contraceptives can also be used in women, and oral isotretinoin is reserved for severe cases under specialist supervision. Dietary modification has no role in the management of acne.

Since the topical preparation did not work for the patient, the next step would be to try an oral antibiotic. The recommended first-line options are lymecycline, oxytetracycline, tetracycline, or doxycycline. Lymecycline is preferred as it only needs to be taken once a day, which can improve the patient’s adherence to the treatment.

Diabetic Foot Ulcers and Infections

Diabetic foot ulcers can be categorized into two types: those in neuropathic feet and those in feet with ischemia. The former is warm and well-perfused with decreased sweating and dry skin, while the latter is cool and pulseless with thin, shiny skin and atrophy of subcutaneous tissues. Diabetic foot infections are serious and range from superficial paronychia to gangrene. Diabetics are more susceptible to foot ulceration due to neuropathy, vascular insufficiency, and reduced neutrophil function. Once skin ulceration occurs, pathogenic organisms can colonize the underlying tissues, and early signs of infection may be subtle. Local signs of wound infection include friable granulation tissue, yellow or grey moist tissue, purulent discharge, and an unpleasant odor. The most common pathogens are aerobic Gram-positive bacteria, particularly Staphylococcus aureus and beta-hemolytic Streptococci. If infection is suspected, deep swab and tissue samples should be sent for culture, and broad-spectrum antibiotics started. Urgent surgical intervention is necessary for a large area of infected sloughy tissue, localised fluctuance and expression of pus, crepitus in the soft tissues on radiological examination, and purplish discoloration of the skin. Antibiotic treatment should be tailored according to the clinical response, culture results, and sensitivity. If osteomyelitis is present, surgical resection should be considered, and antibiotics continued for four to six weeks.

Peri-oral dermatitis cannot be treated with potent steroids as they are not effective. Emollients are also not recommended for improving the condition. Patients are advised to stop using all face care products until the flare-up of peri-oral dermatitis has subsided. The British Association of Dermatology (BAD) provides a useful leaflet on this condition that should be consulted.

Understanding Periorificial Dermatitis

Periorificial dermatitis is a skin condition that is commonly observed in women between the ages of 20 and 45 years old. The use of topical corticosteroids, and to a lesser extent, inhaled corticosteroids, is often linked to the development of this condition. The symptoms of periorificial dermatitis include the appearance of clustered erythematous papules, papulovesicles, and papulopustules, which are typically found in the perioral, perinasal, and periocular regions. However, the skin immediately adjacent to the vermilion border of the lip is usually spared.

When it comes to managing periorificial dermatitis, it is important to note that steroids may actually worsen the symptoms. Instead, the condition should be treated with either topical or oral antibiotics. By understanding the features and management of periorificial dermatitis, individuals can take the necessary steps to address this condition and improve their skin health.

Lamotrigine therapy is associated with a rare but acknowledged adverse effect.

Lamotrigine is a medication that is primarily used as an antiepileptic drug. It is typically prescribed as a second-line treatment for a range of generalised and partial seizures. The drug works by blocking sodium channels in the body, which helps to reduce the occurrence of seizures.

Despite its effectiveness in treating seizures, lamotrigine can also cause a number of adverse effects. One of the most serious of these is Stevens-Johnson syndrome, a rare but potentially life-threatening skin condition. Other possible side effects of the drug include dizziness, headache, nausea, and blurred vision. It is important for patients taking lamotrigine to be aware of these potential risks and to report any unusual symptoms to their healthcare provider.

Understanding Erythrasma: Symptoms, Causes, and Treatment

Erythrasma is a skin condition that is characterized by a flat, slightly scaly, pink or brown rash that is typically found in the groin or axillae. Although it is generally asymptomatic, it can cause discomfort and embarrassment for those who have it. The condition is caused by an overgrowth of the diphtheroid Corynebacterium minutissimum, which is a type of bacteria that is commonly found on the skin.

One way to diagnose erythrasma is through examination with Wood’s light, which reveals a coral-red fluorescence. This can help doctors to distinguish it from other skin conditions that may have similar symptoms.

Fortunately, erythrasma can be treated effectively with topical miconazole or antibacterial medications. In more severe cases, oral erythromycin may be prescribed to help clear up the infection. With proper treatment, most people with erythrasma can expect to see a significant improvement in their symptoms within a few weeks.

Differentiating Venous Ulcers from Other Types of Leg Ulcers

Venous leg ulcers are a common type of leg ulcer in the UK, accounting for around 3% of all new cases attending dermatology clinics. These ulcers are typically large and superficial, and are accompanied by signs of chronic venous insufficiency. This condition leads to venous stasis and increased capillary pressure, resulting in secondary skin changes whose mechanisms are not well understood. Predisposing factors to venous insufficiency include obesity, history of varicose veins, leg trauma, and deep vein thrombosis.

In contrast, arterial ulcers are typically small and punched out, occurring most commonly over a bony prominence such as a malleolus or on the toes. Bowen’s disease, a form of squamous cell carcinoma in situ, commonly occurs on the legs in women but would not reach a size of 5cm in only a month. Neuropathic ulcers, on the other hand, occur on the feet in the context of peripheral neuropathy. Vasculitic ulcers are also a possibility, but there are no clues in the history or findings to suggest their presence.

To differentiate venous ulcers from other types of leg ulcers, it is important to look for corroborating signs of chronic venous insufficiency, such as peripheral edema, venous eczema, haemosiderin deposition, lipodermatosclerosis, and atrophie blanche. Workup should include measurement of the ankle brachial pressure indices (ABPIs) to exclude coexistent arterial disease. If the ABPIs are satisfactory, the cornerstone of management is compression.

Betamethasone valerate cream may not be the most suitable option as it is a lower potency steroid cream.

While calcipotriol/betamethasone dipropionate ointment is commonly used to treat psoriasis, it may not be the most likely diagnosis in this case as psoriasis typically affects the extensor surfaces and doesn’t usually cause severe itching.

Although fexofenadine can provide relief for itching, it is not typically the first choice of treatment.

Permethrin is not used to treat lichen planus, as it is primarily used to treat scabies.

Lichen planus is a skin condition that has an unknown cause, but is believed to be related to the immune system. It is characterized by an itchy rash that appears as small bumps on the palms, soles, genital area, and inner surfaces of the arms. The rash often has a polygonal shape and a distinctive pattern of white lines on the surface, known as Wickham’s striae. In some cases, new skin lesions may appear at the site of trauma, a phenomenon known as the Koebner phenomenon. Oral involvement is common, with around 50% of patients experiencing a white-lace pattern on the buccal mucosa. Nail changes, such as thinning of the nail plate and longitudinal ridging, may also occur.

Lichenoid drug eruptions can be caused by certain medications, including gold, quinine, and thiazides. Treatment for lichen planus typically involves the use of potent topical steroids. For oral lichen planus, benzydamine mouthwash or spray is recommended. In more severe cases, oral steroids or immunosuppressive medications may be necessary. Overall, lichen planus can be a challenging condition to manage, but with proper treatment, symptoms can be controlled and quality of life can be improved.

Acne vulgaris is a common condition that can significantly impact a patient’s quality of life. The severity of acne can range from mild to severe, and in this case, the patient has moderate to severe acne. Treatment with an oral antibiotic is recommended, and a referral to a dermatologist has already been scheduled.

Tetracyclines are typically the first-line treatment for acne vulgaris, but they are contraindicated in pregnant women. This patient is pregnant, so an alternative antibiotic is needed. Oral tetracyclines should also be avoided in breastfeeding women and children under 12 years old due to the risk of deposition in developing teeth and bones.

Erythromycin is a suitable alternative to tetracyclines for the treatment of acne vulgaris in pregnancy. The usual dose is 500 mg twice a day. Some specialists may use trimethoprim, but it is unlicensed for this indication. Women of childbearing age should use effective contraception, especially if using a topical retinoid concomitantly.

Acne vulgaris is a common skin condition that usually affects teenagers and is characterized by the obstruction of hair follicles with keratin plugs, resulting in comedones, inflammation, and pustules. The severity of acne can be classified as mild, moderate, or severe, depending on the number and type of lesions present. Treatment for acne typically involves a step-up approach, starting with single topical therapy and progressing to combination therapy or oral antibiotics if necessary. Tetracyclines are commonly used but should be avoided in certain populations, and a topical retinoid or benzoyl peroxide should always be co-prescribed to reduce the risk of antibiotic resistance. Combined oral contraceptives can also be used in women, and oral isotretinoin is reserved for severe cases under specialist supervision. Dietary modification has no role in the management of acne.

It is likely that the patient is experiencing a severe urticarial rash, which is a common condition that doesn’t require a dermatology appointment or further investigations at this stage. The patient is stable and not showing signs of anaphylaxis. To investigate further, a symptom diary would be sufficient, especially with exposure to different work environments as an archaeologist. The first-line treatment would be a non-sedating antihistamine such as loratadine or cetirizine. However, if the urticaria is severe, as in this case, a short course of oral corticosteroids may be necessary.

Urticaria is a condition characterized by the swelling of the skin, either locally or generally. It is commonly caused by an allergic reaction, although non-allergic causes are also possible. The affected skin appears pale or pink and is raised, resembling hives, wheals, or nettle rash. It is also accompanied by itching or pruritus. The first-line treatment for urticaria is non-sedating antihistamines, while prednisolone is reserved for severe or resistant cases.

Hidradenitis suppurativa is a skin disorder that is chronic, painful, and inflammatory. It is characterized by the presence of nodules, pustules, sinus tracts, and scars in areas where skin folds overlap, such as the armpits, groin, and inner thighs.

This condition is more common in women, smokers, and individuals with a higher body mass index. Over time, the lesions can lead to the development of scars and sinus tracts.

Acanthosis nigricans, on the other hand, is a skin condition characterized by thickening and discoloration of the skin in skin folds. It is often a sign of an underlying disease such as diabetes or malignancy.

Acne vulgaris is another skin condition that can present with papules and pustules, but it typically affects the face, upper back, and chest rather than the areas affected by hidradenitis suppurativa.

Rosacea is a skin condition that causes redness and inflammatory papules on the face, particularly on the cheeks and nose.

Understanding Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic skin disorder that causes painful and inflammatory nodules, pustules, sinus tracts, and scars in intertriginous areas. It is more common in women and typically affects adults under 40. HS occurs due to chronic inflammatory occlusion of folliculopilosebaceous units that obstructs the apocrine glands and prevents keratinocytes from properly shedding from the follicular epithelium. Risk factors include family history, smoking, obesity, diabetes, polycystic ovarian syndrome, and mechanical stretching of skin.

The initial manifestation of HS involves recurrent, painful, and inflamed nodules that can rupture and discharge purulent, malodorous material. The axilla is the most common site, but it can also occur in other areas such as the inguinal, inner thighs, perineal and perianal, and inframammary skin. Coalescence of nodules can result in plaques, sinus tracts, and ‘rope-like’ scarring. Diagnosis is made clinically.

Management of HS involves encouraging good hygiene and loose-fitting clothing, smoking cessation, and weight loss in obese patients. Acute flares can be treated with steroids or antibiotics, and surgical incision and drainage may be needed in some cases. Long-term disease can be treated with topical or oral antibiotics. Lumps that persist despite prolonged medical treatment are excised surgically. Complications of HS include sinus tracts, fistulas, comedones, scarring, contractures, and lymphatic obstruction.

HS can be differentiated from acne vulgaris, follicular pyodermas, and granuloma inguinale. Acne vulgaris primarily occurs on the face, upper chest, and back, whereas HS primarily involves intertriginous areas. Follicular pyodermas are transient and respond rapidly to antibiotics, unlike HS. Granuloma inguinale is a sexually transmitted infection caused by Klebsiella granulomatis and presents as an enlarging ulcer that bleeds in the inguinal area.

Overall, understanding HS is crucial for early diagnosis and effective management of this chronic and painful skin disorder.

Salmon patches are a type of birthmark caused by excess blood vessels, but they typically go away on their own without treatment. These birthmarks are often found in symmetrical patterns on the forehead, eyelids, or nape of the neck.

Cafe-au-lait spots are another type of birthmark that appear as brown patches on the skin. While they are common, they can sometimes be a sign of an underlying medical condition.

Cherry angiomas are small, red bumps that tend to develop later in life.

Port-wine stains are a rare type of birthmark that can darken over time and are often asymmetrical in appearance.

Strawberry naevi are raised, red lesions that typically appear within the first few weeks of life.

Understanding Salmon Patches in Newborns

Salmon patches, also known as stork marks or stork bites, are a type of birthmark that can be found in approximately 50% of newborn babies. These marks are characterized by their pink and blotchy appearance and are commonly found on the forehead, eyelids, and nape of the neck. While they may cause concern for new parents, salmon patches typically fade over the course of a few months. However, marks on the neck may persist. These birthmarks are caused by an overgrowth of blood vessels and are completely harmless. It is important for parents to understand that salmon patches are a common occurrence in newborns and do not require any medical treatment.

Treatment Options for Chronic Plaque Psoriasis

Chronic plaque psoriasis is a skin condition that can be exacerbated by beta-blockers. Therefore, it is important to discontinue the use of beta-blockers and explore alternative prophylactic drugs for migraine in patients with psoriasis. In addition, regular use of emollients is recommended.

For active therapy, potent corticosteroids, vitamin D analogues, dithranol, and tar preparations are all acceptable first-line options. However, corticosteroids and topical vitamin D analogues are typically preferred due to their ease of application and cosmetic acceptability. A Cochrane review found that combining a potent corticosteroid with a vitamin D analogue was the most effective treatment, with a lower incidence of local adverse events. Dovobet®, which combines betamethasone 0.1% with calcipotriol, is one such option. Calcipotriol used alone is also an acceptable alternative treatment.

For psoriasis of the face, flexures, and genitalia, calcineurin inhibitors such as tacrolimus and pimecrolimus are second-line options after moderately potent corticosteroids.

Managing Chronic Plaque Psoriasis: Treatment Options and Considerations

Urticaria is frequently observed as a result of aspirin, despite the fact that all medications have the potential to cause it.

Urticaria, also known as hives, can be caused by various drugs. Some of the most common drugs that can trigger urticaria include aspirin, penicillins, nonsteroidal anti-inflammatory drugs (NSAIDs), and opiates. These medications can cause an allergic reaction in some individuals, leading to the development of hives.

Understanding Dermatitis Herpetiformis

Dermatitis herpetiformis is a skin disorder that is linked to coeliac disease and is caused by the deposition of IgA in the dermis. It is characterized by itchy, vesicular skin lesions that appear on the extensor surfaces such as the elbows, knees, and buttocks.

To diagnose dermatitis herpetiformis, a skin biopsy is performed, and direct immunofluorescence is used to show the deposition of IgA in a granular pattern in the upper dermis.

The management of dermatitis herpetiformis involves a gluten-free diet and the use of dapsone. By adhering to a gluten-free diet, patients can reduce the severity of their symptoms and prevent further damage to their skin. Dapsone is a medication that can help to alleviate the symptoms of dermatitis herpetiformis by reducing inflammation and suppressing the immune system.

In summary, dermatitis herpetiformis is a skin disorder that is associated with coeliac disease and is caused by the deposition of IgA in the dermis. It is characterized by itchy, vesicular skin lesions and can be managed through a gluten-free diet and the use of dapsone.

Understanding Stevens-Johnson Syndrome

Stevens-Johnson syndrome is a severe reaction that affects the skin and mucosa, and is usually caused by a drug reaction. It was previously thought to be a severe form of erythema multiforme, but is now considered a separate entity. The condition can be caused by drugs such as penicillin, sulphonamides, lamotrigine, carbamazepine, phenytoin, allopurinol, NSAIDs, and oral contraceptive pills.

The rash associated with Stevens-Johnson syndrome is typically maculopapular, with target lesions being characteristic. It may develop into vesicles or bullae, and the Nikolsky sign is positive in erythematous areas, meaning that blisters and erosions appear when the skin is rubbed gently. Mucosal involvement and systemic symptoms such as fever and arthralgia may also occur.

Hospital admission is required for supportive treatment of Stevens-Johnson syndrome. It is important to identify and discontinue the causative drug, and to manage the symptoms of the condition. With prompt and appropriate treatment, the prognosis for Stevens-Johnson syndrome can be good.

The development of sinus tracts and fistulas can be a possible complication of hidradenitis suppurativa.

Understanding Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic skin disorder that causes painful and inflammatory nodules, pustules, sinus tracts, and scars in intertriginous areas. It is more common in women and typically affects adults under 40. HS occurs due to chronic inflammatory occlusion of folliculopilosebaceous units that obstructs the apocrine glands and prevents keratinocytes from properly shedding from the follicular epithelium. Risk factors include family history, smoking, obesity, diabetes, polycystic ovarian syndrome, and mechanical stretching of skin.

The initial manifestation of HS involves recurrent, painful, and inflamed nodules that can rupture and discharge purulent, malodorous material. The axilla is the most common site, but it can also occur in other areas such as the inguinal, inner thighs, perineal and perianal, and inframammary skin. Coalescence of nodules can result in plaques, sinus tracts, and ‘rope-like’ scarring. Diagnosis is made clinically.

Management of HS involves encouraging good hygiene and loose-fitting clothing, smoking cessation, and weight loss in obese patients. Acute flares can be treated with steroids or antibiotics, and surgical incision and drainage may be needed in some cases. Long-term disease can be treated with topical or oral antibiotics. Lumps that persist despite prolonged medical treatment are excised surgically. Complications of HS include sinus tracts, fistulas, comedones, scarring, contractures, and lymphatic obstruction.

HS can be differentiated from acne vulgaris, follicular pyodermas, and granuloma inguinale. Acne vulgaris primarily occurs on the face, upper chest, and back, whereas HS primarily involves intertriginous areas. Follicular pyodermas are transient and respond rapidly to antibiotics, unlike HS. Granuloma inguinale is a sexually transmitted infection caused by Klebsiella granulomatis and presents as an enlarging ulcer that bleeds in the inguinal area.

Overall, understanding HS is crucial for early diagnosis and effective management of this chronic and painful skin disorder.

The presence of a malar rash, arthralgia, lethargy, and a history of mental health issues suggest a possible diagnosis of SLE. It is important to note that the CRP levels are usually within normal range in SLE, unlike the ESR.

Understanding Systemic Lupus Erythematosus: A Multisystem Autoimmune Disorder

Systemic lupus erythematosus (SLE) is a complex autoimmune disorder that affects multiple systems in the body. It typically develops in early adulthood and is more common in women and individuals of Afro-Caribbean descent. The condition is characterized by a range of symptoms, including fatigue, fever, mouth ulcers, and lymphadenopathy.

SLE can also affect the skin, causing a malar (butterfly) rash that spares the nasolabial folds, as well as a discoid rash that is scaly, erythematous, and well-demarcated in sun-exposed areas. Other skin symptoms may include photosensitivity, Raynaud’s phenomenon, livedo reticularis, and non-scarring alopecia.

Musculoskeletal symptoms of SLE may include arthralgia and non-erosive arthritis, while cardiovascular symptoms may include pericarditis and myocarditis. Respiratory symptoms may include pleurisy and fibrosing alveolitis, and renal symptoms may include proteinuria and glomerulonephritis, with diffuse proliferative glomerulonephritis being the most common type.

Finally, neuropsychiatric symptoms of SLE may include anxiety and depression, psychosis, and seizures. Overall, SLE is a complex and challenging condition that requires careful management and ongoing support.

Understanding Lentigo Maligna: A Guide to Identifying and Differentiating from Other Skin Lesions

Lentigo maligna is a type of malignant melanoma in situ that is commonly found on sun-damaged skin, particularly on the face and neck. It is characterized by a pigmented lesion that is growing and has a slightly irregular border, with a diameter of over 0.6 cm. Lentigo maligna grows slowly over a period of 5 to 20 years or longer, and can be recognized using the ABCDE rule: Asymmetry, Border irregularity, Colour variation, large Diameter, and Evolving.

It is important to differentiate lentigo maligna from other skin lesions, such as melanocytic naevus, lentigo, seborrhoeic keratosis, and post-inflammatory hyperpigmentation. Melanocytic naevus is typically flesh-colored and protruding, while lentigo is benign and has lighter pigmentation. Seborrhoeic keratosis has a warty surface and can be dark-colored, leading to concern that it may be a malignant melanoma. Post-inflammatory hyperpigmentation can follow any inflammatory condition, but there is no history to suggest this in the case of lentigo maligna.

It may be difficult to determine whether invasive change has occurred in lentigo maligna just from appearance, but suspicious changes include thickening of part of the lesion, more variation in color, ulceration or bleeding, or itching. It is important to seek medical attention if any of these changes occur.

Stevens-Johnson syndrome is a rare but known negative effect of lamotrigine treatment. This skin condition typically manifests within a few days of starting the medication and can cause flu-like symptoms such as fever, malaise, myalgia, and arthralgia. Painful erythema with blisters or ulcers is a hallmark of the syndrome, which can progress to areas of confluent erythema with skin loss. Mucosal involvement is also common, affecting the eyes, lips, mouth, oesophagus, upper respiratory tract (causing cough and respiratory distress), genitalia, and gastrointestinal tract (resulting in diarrhoea).

Other drugs, such as aspirin, macrolides, opiates, and cyclosporin, can also cause drug rashes. Exanthematous eruptions are a common type of drug rash, characterised by pink-to-red macules that blanch on pressure.

Urticaria and erythema multiforme are other types of drug-related rashes. Aspirin and anticonvulsants are associated with erythema multiforme, which typically presents as spot or target lesions and doesn’t involve mucosal tissues.

Lamotrigine is a medication that is primarily used as an antiepileptic drug. It is typically prescribed as a second-line treatment for a range of generalised and partial seizures. The drug works by blocking sodium channels in the body, which helps to reduce the occurrence of seizures.

Despite its effectiveness in treating seizures, lamotrigine can also cause a number of adverse effects. One of the most serious of these is Stevens-Johnson syndrome, a rare but potentially life-threatening skin condition. Other possible side effects of the drug include dizziness, headache, nausea, and blurred vision. It is important for patients taking lamotrigine to be aware of these potential risks and to report any unusual symptoms to their healthcare provider.
