Contrasting molecular epidemiology of group A streptococci causing tropical and nontropical infections of the skin and throat. (1/59)
Disease caused by group A streptococci (GAS) in tropical regions often takes the form of impetigo, whereas pharyngitis tends to predominate in temperate zones. GAS derived from asymptomatic throat infections and pyoderma lesions of rural Aboriginal Australians were evaluated for phylogenetic distant emm genes, which represent ecological markers for tissue site preference. On the basis of the percentage of total isolates from a given tissue, emm pattern A-C organisms exhibited a stronger predilection for the throat, whereas pattern D organisms preferred the skin. Only 16% of isolates collected by active surveillance displayed pattern A-C, which reflects the low incidence of oropharyngeal infection. Importantly, most (70%) pattern A-C organisms were isolated from skin sores, despite their innate tendency to infect the throat. Combined with findings from nontropical populations, analysis of the data supports the hypothesis that GAS tissue preferences are genetically predetermined and that host risk factors for infection strongly influence the differential reproduction of individual clones. (+info)A new M-type of group A streptococcus of clinical importance in pyoderma and pharyngitis. (2/59)
A new M-type of group A streptococcus, provisionally designated type 65, is described. The vaccine and other initially isolated strains of this type attracted attention because of the T-agglutination reactions 2/25, not previously encountered among pyoderma streptococci. The investigations characterizing the strains as members of a new type were done with streptococci isolated from patients with pyoderma. However, type 65 was subsequently found to cause both pyoderma and acute pharyngitis. The T-2 agglutination reactions encountered with original members of this type, plus the cross-reactions later seen with type 65 antiserum and M-type 2 streptococci, prompted a comparison of this new type with M-type 2 streptococci, including those with the T-2 agglutination and others with the 8-25-Imp. 19 complex. The two M-antigens were clearly distinguished from one another in reciprocal bactericidal and precipitin tests with absorbed antisera. They were further distinguished in that all type 65 strains were opacity-factor (OF) negative, whereas type 2 streptococci were uniformly OF-positive. Most M-type 65 strains subsequently found in surveillance studies were shown to be members of the 8-25-Imp,19 T-complex. Type 65 is thus a newly described type which shares with M-types 55 and 57 a commom T-agglutination pattern and, like members of these types, fails to produce opacity factor. In our colleciton of strains, from both pyoderma and pharyngitis, shown to be members of the 8-25-Imp. 19 complex, and OF-negative, only type 65 has been identified to date. In contrast to types 55 and 57, the new type 65 does not appear to be of major importance in causing acute glomerulonephritis. (+info)Streptococcal pyoderma of the penis following fellatio. (3/59)
Gonococcal pharyngitis has been correlated with fellatio in both heterosexual females and homosexual males. This report describes another complication of fellatio, group A beta-eaemolytic streptococcal pyroderma on the penis after exposure to a male who probably had pharyngitis. the erythematous, purulent lesions should be cultured. After the organism has been identified, adequate treatment with either a long-acting parenteral penicillin or a 10-day course of oral penicillin is important in order to prevent the possible life-threatening complication of post-streptococcal glomerulonephritis. (+info)Generalized seborrhoeic dermatitis. Clinical and therapeutic data of 25 patients. (4/59)
Twenty-five infants with generalized seborrhoeic dermatitis have been studied with reference to the provision of optimum treatment. Leucocyte counts and chest x-ray examination are recommended in every case. Irrespective of clinical findings, antibiotics should be given to patients with overt bacterial infection and those with leucocytosis, shift to the left, and toxic granulation. One group of infants was treated with vitamin B complex plus biotin given slowly intravenously over 24 hours; a second group was given only biotin intravenously over 2-3 hours; and a third group only biotin over 1-2 minutes. A fourth group was treated with both biotin and antibiotics for confirmed or suspected superimposed bacterial infection. The results were excellent in all groups. Skin lesions improved within 4-8 days and cleared completely within 15-30 days. Intravenous administration of biotin is recommended as less painful and less dangerous than multiple intramuscular injections. (+info)Benefits of swimming pools in two remote Aboriginal communities in Western Australia: intervention study. (5/59)
OBJECTIVE: To determine the health impact of swimming pools built with the aim of improving quality of life and reducing high rates of pyoderma and otitis media. DESIGN: Intervention study assessing prevalence of ear disease and skin infections before and at six monthly intervals after opening of swimming pools. SETTING: Two remote Aboriginal communities in Western Australia. PARTICIPANTS: 84 boys and 78 girls aged < 17 years. MAIN OUTCOME MEASURES: Changes in prevalence and severity of pyoderma and perforation of tympanic membranes with or without otorrhoea over 18 months after opening of pools. RESULTS: In community A, 61 children were seen before the pool was opened, and 41, 46, and 33 children were seen at the second, third, and fourth surveys. Equivalent figures for community B were 60, 35, 39, and 45. Prevalence of pyoderma declined significantly from 62% to 18% in community A and from 70% to 20% in community B during the 18 months after the pools opened. Over the same period, prevalence of severe pyoderma fell from 30% to 15% in community A and from 48% to 0% in community B. Prevalence of perforations of the tympanic membrane fell from 32% in both communities to 13% in community A and 18% in community B. School attendance improved in community A. CONCLUSION: Swimming pools in remote communities were associated with reduction in prevalence of pyoderma and tympanic membrane perforations, which could result in long term benefits through reduction in chronic disease burden and improved educational and social outcomes. (+info)Biotypes of group A streptococci isolated from children. (6/59)
Thirty-eight isolates of group A streptococci from patients with pharyngitis, 13 isolates from patients with pyoderma and 28 carrier strains were subjected to biotyping by carbohydrate fermentation tests and production of beta-glucuronidase. Biotype 10 was observed most frequently among clinical isolates and biotypes 3 and 4 were most common among carrier isolates. (+info)Pattern of pediatric dermatoses in a referral center in South India. (7/59)
This study was undertaken to determine the pattern of dermatoses in children in south India. All children <14 years presenting to us between May 2001 and June 2002 were recruited. A total of 2100 children (males -995; females- 1105) with 2144 dermatoses were recorded. Infections and infestations were the most common dermatoses (54.5%) followed by dermatitis and eczema (8.6%), pigmentary disorders (5.7%), insect bite reaction (5.27%), hair and nail disorders (5.2%), miliaria (4.1%), nutritional deficiency disorders (2.8%), urticaria (2.5%), genetic disorders (2.1%), psoriasis (1.4%), collagen vascular disorders (0.5%), hemangiomas (0.5%), drug eruptions (0.3%), pityriasis rosea (0.2%) and others (5.8%). Pyodermas were the most common dermatoses (47.13%) followed by scabies (30.6%) amongst infections and infestations. Atopic dermatitis was noticed only in 3 patients. Insect bite reactions (papular urticaria) (5.27%) and miliaria (4.1%) were attributed to the tropical weather conditions in this coastal area. Genetic disorders including ichthyosis and palmoplantar keratoderma contributed to 2.1% of cases and could be due to the high incidence of consanguinous marriages in this society. (+info)Invasive group A streptococcal infection in high school football players, New York City, 2003. (8/59)
After being notified that 2 high school football teammates from New York City were hospitalized with confirmed or suspected invasive group A streptococcal infections, we conducted an investigation of possible spread among other team members. This investigation highlights a need for guidelines on management of streptococcal and other infectious disease outbreaks in team sport settings. (+info)Pyoderma is a term used in medicine to describe a bacterial skin infection. It's derived from two Greek words: "pyon" meaning pus and "derma" meaning skin.
The infection can result in inflammation, often characterized by redness, swelling, warmth, and pain. Pus-filled blisters or boils may also form, which can rupture and crust over as the infection progresses.
Pyoderma can occur in people of all ages but is particularly common in children. The causative bacteria are often Staphylococcus aureus or Streptococcus pyogenes. The condition can be superficial, affecting only the top layer of the skin (epidermis), or it can be deeper, involving the dermis and/or subcutaneous tissue.
Treatment typically involves antibiotics, either topical or oral, depending on the severity and extent of the infection. In some cases, drainage of pus-filled abscesses may be necessary. Preventive measures such as good hygiene and keeping skin clean and dry can help reduce the risk of pyoderma.
A skin ulcer is a defined as a loss of continuity or disruption of the skin surface, often accompanied by inflammation and/or infection. These lesions can result from various causes including pressure, venous or arterial insufficiency, diabetes, and chronic dermatological conditions. Skin ulcers are typically characterized by their appearance, depth, location, and underlying cause. Common types of skin ulcers include pressure ulcers (also known as bedsores), venous leg ulcers, arterial ulcers, and diabetic foot ulcers. Proper evaluation, wound care, management of underlying conditions, and prevention strategies are crucial in the treatment of skin ulcers to promote healing and prevent complications.
Penile diseases refer to a range of medical conditions that affect the penis, including infections, inflammatory conditions, and structural abnormalities. Some common penile diseases include:
1. Balanitis: an infection or inflammation of the foreskin and/or head of the penis.
2. Balanoposthitis: an infection or inflammation of both the foreskin and the head of the penis.
3. Phimosis: a condition in which the foreskin is too tight to be pulled back over the head of the penis.
4. Paraphimosis: a medical emergency in which the foreskin becomes trapped behind the head of the penis and cannot be returned to its normal position.
5. Peyronie's disease: a condition characterized by the development of scar tissue inside the penis, leading to curvature during erections.
6. Erectile dysfunction: the inability to achieve or maintain an erection sufficient for sexual intercourse.
7. Penile cancer: a rare form of cancer that affects the skin and tissues of the penis.
These conditions can have various causes, including bacterial or fungal infections, sexually transmitted infections (STIs), skin conditions, trauma, or underlying medical conditions. Treatment for penile diseases varies depending on the specific condition and its severity, but may include medications, surgery, or lifestyle changes.
Infectious skin diseases are conditions characterized by an infection or infestation of the skin caused by various microorganisms such as bacteria, viruses, fungi, or parasites. These organisms invade the skin, causing inflammation, redness, itching, pain, and other symptoms. Examples of infectious skin diseases include:
1. Bacterial infections: Cellulitis, impetigo, folliculitis, and MRSA (methicillin-resistant Staphylococcus aureus) infections are examples of bacterial skin infections.
2. Viral infections: Herpes simplex virus (HSV), varicella-zoster virus (VZV), human papillomavirus (HPV), and molluscum contagiosum are common viruses that can cause skin infections.
3. Fungal infections: Tinea pedis (athlete's foot), tinea corporis (ringworm), candidiasis (yeast infection), and pityriasis versicolor are examples of fungal skin infections.
4. Parasitic infestations: Scabies, lice, and bed bugs are examples of parasites that can cause infectious skin diseases.
Treatment for infectious skin diseases depends on the underlying cause and may include topical or oral antibiotics, antiviral medications, antifungal treatments, or insecticides to eliminate parasitic infestations. Proper hygiene, wound care, and avoiding contact with infected individuals can help prevent the spread of infectious skin diseases.
Sweet syndrome, also known as acute febrile neutrophilic dermatosis, is a skin condition characterized by the rapid onset of painful, red, and swollen skin lesions. The lesions are often accompanied by fever and elevated white blood cell count, particularly an increase in neutrophils.
The medical definition of Sweet syndrome includes the following criteria:
1. Abrupt onset of painful, erythematous (red), and edematous (swollen) papules, plaques, or nodules.
2. Fever greater than 38°C (100.4°F).
3. Leukocytosis with a predominance of neutrophils in the peripheral blood.
4. Histopathological evidence of a dense dermal infiltrate of neutrophils without evidence of vasculitis.
5. Rapid response to systemic corticosteroids.
Sweet syndrome can be associated with various medical conditions, such as infections, malignancies, and inflammatory diseases, or it can occur without an identifiable underlying cause (idiopathic).
A leg ulcer is a chronic wound that occurs on the lower extremities, typically on the inner or outer ankle. It's often caused by poor circulation, venous insufficiency, or diabetes. Leg ulcers can also result from injury, infection, or inflammatory diseases such as rheumatoid arthritis or lupus. These ulcers can be painful, and they may take a long time to heal, making them prone to infection. Proper diagnosis, treatment, and wound care are essential for healing leg ulcers and preventing complications.
Acne vulgaris is a common skin condition characterized by the formation of various types of blemishes on the skin, such as blackheads, whiteheads, papules, pustules, and cysts or nodules. These lesions typically appear on areas of the body that have a high concentration of sebaceous glands, including the face, neck, chest, back, and shoulders.
Acne vulgaris occurs when hair follicles become clogged with dead skin cells and excess oil (sebum) produced by the sebaceous glands. This blockage provides an ideal environment for bacteria, particularly Propionibacterium acnes, to multiply, leading to inflammation and infection. The severity of acne vulgaris can range from mild with only a few scattered comedones (blackheads or whiteheads) to severe cystic acne, which can cause significant scarring and emotional distress.
The exact causes of acne vulgaris are not fully understood, but several factors contribute to its development, including:
1. Hormonal changes during puberty, menstruation, pregnancy, or due to conditions like polycystic ovary syndrome (PCOS)
2. Genetic predisposition
3. Use of certain medications, such as corticosteroids and lithium
4. Excessive production of sebum due to overactive sebaceous glands
5. Accumulation of dead skin cells that clog pores
6. Bacterial infection (particularly Propionibacterium acnes)
7. Inflammation caused by the body's immune response to bacterial infection and clogged pores
Treatment for acne vulgaris depends on its severity and can include over-the-counter or prescription topical treatments, oral medications, chemical peels, light therapies, or even hormonal therapies in some cases. It is essential to seek professional medical advice from a dermatologist or healthcare provider to determine the most appropriate treatment plan for individual needs.
Hidradenitis suppurativa (HS) is a chronic, inflammatory skin condition that typically affects areas of the body where there are sweat glands, such as the armpits, groin, and buttocks. The main features of HS are recurrent boil-like lumps or abscesses (nodules) that form under the skin. These nodules can rupture and drain pus, leading to painful, swollen, and inflamed lesions. Over time, these lesions may heal, only to be replaced by new ones, resulting in scarring and tunnel-like tracts (sinus tracts) beneath the skin.
HS is a debilitating condition that can significantly impact an individual's quality of life, causing physical discomfort, emotional distress, and social isolation. The exact cause of HS remains unclear, but it is thought to involve a combination of genetic, hormonal, and environmental factors. Treatment options for HS include topical and oral antibiotics, biologic therapies, surgical interventions, and lifestyle modifications, such as weight loss and smoking cessation.
Erythema nodosum is a type of inflammation that occurs in the fatty layer of the skin, causing painful, red or purple bumps (nodules) to form. It is a type of panniculitis, which refers to any condition that causes inflammation of the fatty layer of tissue beneath the skin.
Erythema nodosum is often associated with a variety of underlying conditions, such as infections (e.g., streptococcus, tuberculosis), medications (e.g., sulfa drugs, oral contraceptives), inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis), and pregnancy.
The bumps associated with erythema nodosum typically appear on the shins, ankles, knees, or other areas of the legs, although they can also occur on the arms, hands, or face. The bumps may be tender to the touch, warm, and swollen, and they may cause pain or discomfort when walking or standing for prolonged periods.
In most cases, erythema nodosum resolves on its own within a few weeks to several months, although symptoms can be managed with medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. Treating the underlying condition is also important for resolving erythema nodosum and preventing recurrences.
Tooth mobility, also known as loose teeth, refers to the degree of movement or displacement of a tooth in its socket when lateral forces are applied. It is often described in terms of grades:
* Grade 1: Tooth can be moved slightly (up to 1 mm) with finger pressure.
* Grade 2: Tooth can be moved up to 2 mm with finger pressure.
* Grade 3: Tooth can be moved more than 2 mm or can be removed from its socket with manual pressure.
Increased tooth mobility can be a sign of periodontal disease, trauma, or other dental conditions and should be evaluated by a dentist. Treatment may include deep cleaning, splinting, or surgery to restore stability to the affected teeth.
There is no medical definition for "dog diseases" as it is too broad a term. However, dogs can suffer from various health conditions and illnesses that are specific to their species or similar to those found in humans. Some common categories of dog diseases include:
1. Infectious Diseases: These are caused by viruses, bacteria, fungi, or parasites. Examples include distemper, parvovirus, kennel cough, Lyme disease, and heartworms.
2. Hereditary/Genetic Disorders: Some dogs may inherit certain genetic disorders from their parents. Examples include hip dysplasia, elbow dysplasia, progressive retinal atrophy (PRA), and degenerative myelopathy.
3. Age-Related Diseases: As dogs age, they become more susceptible to various health issues. Common age-related diseases in dogs include arthritis, dental disease, cancer, and cognitive dysfunction syndrome (CDS).
4. Nutritional Disorders: Malnutrition or improper feeding can lead to various health problems in dogs. Examples include obesity, malnutrition, and vitamin deficiencies.
5. Environmental Diseases: These are caused by exposure to environmental factors such as toxins, allergens, or extreme temperatures. Examples include heatstroke, frostbite, and toxicities from ingesting harmful substances.
6. Neurological Disorders: Dogs can suffer from various neurological conditions that affect their nervous system. Examples include epilepsy, intervertebral disc disease (IVDD), and vestibular disease.
7. Behavioral Disorders: Some dogs may develop behavioral issues due to various factors such as anxiety, fear, or aggression. Examples include separation anxiety, noise phobias, and resource guarding.
It's important to note that regular veterinary care, proper nutrition, exercise, and preventative measures can help reduce the risk of many dog diseases.
Rheumatic fever is a systemic inflammatory disease that may occur following an untreated Group A streptococcal infection, such as strep throat. It primarily affects children between the ages of 5 and 15, but it can occur at any age. The condition is characterized by inflammation in various parts of the body, including the heart (carditis), joints (arthritis), skin (erythema marginatum, subcutaneous nodules), and brain (Sydenham's chorea).
The onset of rheumatic fever usually occurs 2-4 weeks after a streptococcal infection. The exact cause of the immune system's overreaction leading to rheumatic fever is not fully understood, but it involves molecular mimicry between streptococcal antigens and host tissues.
The Jones Criteria are used to diagnose rheumatic fever, which include:
1. Evidence of a preceding streptococcal infection (e.g., positive throat culture or rapid strep test, elevated or rising anti-streptolysin O titer)
2. Carditis (heart inflammation), including new murmurs or changes in existing murmurs, electrocardiogram abnormalities, or evidence of heart failure
3. Polyarthritis (inflammation of multiple joints) – typically large joints like the knees and ankles, migratory, and may be associated with warmth, swelling, and pain
4. Erythema marginatum (a skin rash characterized by pink or red, irregularly shaped macules or rings that blanch in the center and spread outward)
5. Subcutaneous nodules (firm, round, mobile lumps under the skin, usually over bony prominences)
6. Sydenham's chorea (involuntary, rapid, irregular movements, often affecting the face, hands, and feet)
Treatment of rheumatic fever typically involves antibiotics to eliminate any residual streptococcal infection, anti-inflammatory medications like corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs) to manage symptoms and prevent long-term heart complications, and secondary prophylaxis with regular antibiotic administration to prevent recurrent streptococcal infections.
Staphylococcal skin infections are a type of skin infection caused by Staphylococcus aureus (S. aureus) bacteria, which commonly live on the skin and inside the nose without causing harm. However, if they enter the body through a cut or scratch, they can cause an infection.
There are several types of staphylococcal skin infections, including:
1. Impetigo: A highly contagious superficial skin infection that typically affects children and causes red, fluid-filled blisters that burst and leave a yellowish crust.
2. Folliculitis: An inflammation of the hair follicles that causes red, pus-filled bumps or pimples on the skin.
3. Furunculosis: A deeper infection of the hair follicle that forms a large, painful lump or boil under the skin.
4. Cellulitis: A potentially serious bacterial infection that affects the deeper layers of the skin and can cause redness, swelling, warmth, and pain in the affected area.
5. Abscess: A collection of pus that forms in the skin, often caused by a staphylococcal infection.
Treatment for staphylococcal skin infections typically involves antibiotics, either topical or oral, depending on the severity and location of the infection. In some cases, drainage of pus or other fluids may be necessary to promote healing. Preventing the spread of staphylococcal skin infections involves good hygiene practices, such as washing hands frequently, covering wounds and cuts, and avoiding sharing personal items like towels or razors.
Ecthyma is a deep skin infection that penetrates below the superficial skin layer (dermis) and is characterized by the formation of ulcers or crusty lesions. It is typically caused by group A Streptococcus or Staphylococcus aureus bacteria and can occur in individuals with compromised immune systems, poor hygiene, or exposure to unhygienic conditions.
The infection usually begins as a papule or pustule, which then develops into a shallow ulcer with a necrotic base and raised edges. The lesion may be painful, pruritic (itchy), and can take several weeks to heal, often leaving scars. In severe cases, ecthyma can lead to complications such as lymphangitis, cellulitis, or bacteremia.
Treatment typically involves the use of systemic antibiotics, topical antiseptics, and wound care to promote healing and prevent scarring. Preventive measures include maintaining good hygiene, prompt treatment of skin injuries, and addressing underlying conditions that may increase the risk of infection.
Pyoderma gangrenosum is a rare, inflammatory skin condition that typically begins as a small pustule or blister, which then rapidly progresses to form painful ulcers with a characteristic violaceous (bluish-purple) undermined border. The etiology of pyoderma gangrenosum is not entirely clear, but it's often associated with an underlying systemic disease, such as inflammatory bowel disease, rheumatoid arthritis, or hematologic disorders.
The pathophysiology of pyoderma gangrenosum involves a dysregulated immune response and neutrophil-mediated tissue damage. Diagnosis is often based on the clinical presentation and exclusion of other conditions with similar lesions. Treatment typically includes systemic immunosuppressive therapy, such as corticosteroids, cyclosporine, or biologic agents, along with local wound care to promote healing and prevent infection.
It's important to note that pyoderma gangrenosum can be a challenging condition to manage, and a multidisciplinary approach involving dermatologists, internists, and surgeons may be necessary for optimal care.
Impetigo is a common and highly contagious skin infection that mainly affects infants and children. It is caused by two types of bacteria, namely Staphylococcus aureus and Streptococcus pyogenes (Group A streptococcus). The infection typically occurs in areas of the body with broken or damaged skin, such as cuts, scrapes, insect bites, or rashes.
There are two forms of impetigo: non-bullous and bullous. Non-bullous impetigo, also known as crusted impetigo, begins as small blisters or pimples that quickly rupture, leaving a yellowish-crusted, honey-colored scab. These lesions can be itchy and painful, and they often occur around the nose, mouth, and hands. Non-bullous impetigo is more commonly caused by Streptococcus pyogenes.
Bullous impetigo, on the other hand, is characterized by larger fluid-filled blisters that are usually painless and do not itch. These blisters can appear anywhere on the body but are most common in warm, moist areas such as the armpits, groin, or diaper region. Bullous impetigo is primarily caused by Staphylococcus aureus.
Impetigo is typically treated with topical antibiotics, such as mupirocin (Bactroban) or retapamulin (Altabax), applied directly to the affected area. In more severe cases, oral antibiotics may be prescribed. It is essential to cover the lesions and maintain good hygiene practices to prevent the spread of impetigo to others.
Tinea is a common fungal infection of the skin, also known as ringworm. It's called ringworm because of its characteristic red, circular, and often scaly rash with raised edges that can resemble a worm's shape. However, it has nothing to do with any kind of actual worm.
The fungi responsible for tinea infections belong to the genus Trichophyton, Microsporum, or Epidermophyton. These fungi thrive in warm, damp environments and can be contracted from infected people, animals, or contaminated soil. Common types of tinea infections include athlete's foot (tinea pedis), jock itch (tinea cruris), and ringworm of the scalp (tinea capitis).
Treatment for tinea typically involves antifungal medications, either topical or oral, depending on the location and severity of the infection. Proper hygiene and avoiding sharing personal items can help prevent the spread of this contagious condition.
Scabies is a contagious skin condition caused by the infestation of the human itch mite (Sarcoptes scabiei var. hominis). The female mite burrows into the upper layer of the skin, where it lays its eggs and causes an intensely pruritic (itchy) rash. The rash is often accompanied by small red bumps and blisters, typically found in areas such as the hands, wrists, elbows, armpits, waistline, genitals, and buttocks. Scabies is transmitted through direct skin-to-skin contact with an infected individual or through sharing of contaminated items like bedding or clothing. It can affect people of all ages, races, and socioeconomic backgrounds, but it is particularly common in crowded living conditions, nursing homes, and child care facilities. Treatment usually involves topical medications or oral drugs that kill the mites and their eggs, as well as thorough cleaning and laundering of bedding, clothing, and towels to prevent reinfestation.
A carbuncle is a deep skin infection that often involves a group of hair follicles. It is a more severe form of a boil and can be quite painful. Carbuncles usually occur in people who have underlying health issues such as diabetes or a weakened immune system. They typically appear as red, swollen, and painful lumps on the skin that may release pus. Treatment for carbuncles usually involves antibiotics to clear up the infection and proper care of the wound to prevent complications.
