Diverse developing mouse lineages exhibit high-level c-Myb expression in immature cells and loss of expression upon differentiation. (1/1203)
The c-myb gene encodes a sequence specific transactivator that is required for fetal hematopoiesis, but its potential role in other tissues is less clear because of the early fetal demise of mice with targeted deletions of the c-myb gene and incomplete of knowledge about c-myb's expression pattern. In the hematopoietic system, c-Myb protein acts on target genes whose expression is restricted to individual lineages, despite Myb's presence and role in multiple immature lineages. This suggests that c-Myb actions within different cell type-specific contexts are strongly affected by combinatorial interactions. To consider the possibility of similar c-Myb actions could extend into non-hematopoietic systems in other cell and tissue compartments, we characterized c-myb expression in developing and adult mice using in situ hybridization and correlated this with stage-specific differentiation and mitotic activity. Diverse tissues exhibited strong c-myb expression during development, notably tooth buds, the thyroid primordium, developing trachea and proximal branching airway epithelium, hair follicles, hematopoietic cells, and gastrointestinal crypt epithelial cells. The latter three of these all maintained high expression into adulthood, but with characteristic restriction to immature cell lineages prior to their terminal differentiation. In all sites, during fetal and adult stages, loss of c-Myb expression correlated strikingly with the initiation of terminal differentiation, but not the loss of mitotic activity. Based on these data, we hypothesize that c-Myb's function during cellular differentiation is both an activator of immature gene expression and a suppressor of terminal differentiation in diverse lineages. (+info)WNT signaling in the control of hair growth and structure. (2/1203)
Characterization of the molecular pathways controlling differentiation and proliferation in mammalian hair follicles is central to our understanding of the regulation of normal hair growth, the basis of hereditary hair loss diseases, and the origin of follicle-based tumors. We demonstrate that the proto-oncogene Wnt3, which encodes a secreted paracrine signaling molecule, is expressed in developing and mature hair follicles and that its overexpression in transgenic mouse skin causes a short-hair phenotype due to altered differentiation of hair shaft precursor cells, and cyclical balding resulting from hair shaft structural defects and associated with an abnormal profile of protein expression in the hair shaft. A putative effector molecule for WNT3 signaling, the cytoplasmic protein Dishevelled 2 (DVL2), is normally present at high levels in a subset of cells in the outer root sheath and in precursor cells of the hair shaft cortex and cuticle which lie immediately adjacent to Wnt3-expressing cells. Overexpression of Dvl2 in the outer root sheath mimics the short-hair phenotype produced by overexpression of Wnt3, supporting the hypothesis that Wnt3 and Dvl2 have the potential to act in the same pathway in the regulation of hair growth. These experiments demonstrate a previously unrecognized role for WNT signaling in the control of hair growth and structure, as well as presenting the first example of a mammalian phenotype resulting from overexpression of a Dvl gene and providing an accessible in vivo system for analysis of mammalian WNT signaling pathways. (+info)Procyanidin oligomers selectively and intensively promote proliferation of mouse hair epithelial cells in vitro and activate hair follicle growth in vivo. (3/1203)
We have previously reported that proanthocyanidins extracted from grape seeds possess growth-promoting activity toward murine hair epithelial cells in vitro and stimulate anagen induction in hair cycle progression in vivo. This report constitutes a comparison of the growth-promoting activity of procyanidin oligomers and the target cells of procyanidins in the skin. Results show that procyanidin dimer and trimer exhibit higher growth-promoting activity than the monomer. The maximum growth-promoting activity for hair epithelial cells with procyanidin B-2, an epicatechin dimer, reached about 300% (30 microM) relative to controls (= 100%) in a 5 d culture. Optimum concentration of procyanidin C-1, an epicatechin trimer, was lower than that of procyanidin B-2; the maximum growth-promoting activity of procyanidin C-1 was about 220% (3 microM). No other flavonoid compounds examined exhibit higher proliferative activities than the procyanidins. In skin constituent cells, only epithelial cells such as hair keratinocytes or epidermal keratinocytes respond to procyanidin oligomers. Topical application of 1% procyanidin oligomers on shaven C3H mice in the telogen phase led to significant hair regeneration [procyanidin B-2, 69.6% +/- 21.8% (mean +/- SD); procyanidin B-3, 80.9% +/- 13.0%; procyanidin C-1, 78.3% +/- 7.6%] on the basis of the shaven area; application of vehicle only led to regeneration of 41.7% (SD = 16.3%). In this paper, we demonstrate the hair-growing activity of procyanidin oligomers both in vitro and in vivo, and their potential for use as agents to induce hair growth. (+info)Topical gene delivery to murine skin. (4/1203)
We topically applied naked plasmid DNA containing the luciferase or chloramphenicol acetyltransferase cDNA directly to mouse skin. Gene expression was detected in skin samples as early as 4 h after DNA application, plateaued from 16 to 72 h post-application, and had decreased significantly by 7 d post-application. Reporter gene activity following topical DNA delivery was comparable with that produced by intradermal injection of DNA. Plasmid DNA at concentrations > or =0.25 microg per microl were required to achieve maximal expression levels. Reporter gene expression following topical administration was largely confined to the superficial layers of the epidermis and to hair follicles. Surprisingly, certain cationic liposomes inhibited the efficiency of cutaneous gene transfer. This technique provides a simple, clinically relevant approach to deliver genes to the skin, with potential application in treating a variety of cutaneous disorders. (+info)Association between mouse nude gene expression and the initiation of epithelial terminal differentiation. (5/1203)
Loss-of-function mutations in Whn (Hfh 11), a winged-helix/forkhead transcription factor, result in the nude mouse phenotype. To determine the whn expression pattern during development, we utilized mice in which a beta-galactosidase reporter gene was placed under the control of the wild-type whn promoter by homologous recombination (M. Nehls et al., 1996, Science 272, 886-889). Sites of reporter expression were confirmed by immunohistochemical staining for Whn protein or by in situ hybridization for whn mRNA. At all developmental stages, whn expression is restricted to epithelial cells. In addition to the skin and thymus, whn is expressed in the developing nails, nasal passages, tongue, palate, and teeth. In embryonic epidermis, suprabasal cells induce whn expression at the same time that terminal differentiation markers first appear. As the epidermis matures, whn promoter activity is found primarily in the first suprabasal layer, which contains keratinocytes in the early stages of terminal differentiation. In developing and mature anagen hair follicles, whn is expressed at high levels in the postmitotic precursor cells of the hair shaft and inner root sheath. Though principally associated with terminal differentiation, whn expression is also detected in progenitor cell compartments; in the hair bulb matrix and basal epidermal layer, a small subclass of cells expresses whn, while in the outer root sheath, whn promoter activity is induced as the follicle completes its elongation. Within these compartments, rare cells exhibit both whn expression and the nuclear proliferation marker Ki-67. The results suggest that whn expression encompasses the transition from a proliferative to a postmitotic state and that whn regulates the initiation of terminal differentiation. (+info)UVB irradiation stimulates deposition of new elastic fibers by modified epithelial cells surrounding the hair follicles and sebaceous glands in mice. (6/1203)
UVB irradiation stimulates the synthesis of elastin in the skin of humans and experimental animals. In this study we localized the site and the cells that are responsible for the synthesis of murine dermal elastic fibers. SKH-1 hairless mice were irradiated with UVB and the skin removed for light microscopy, electron microscopy, in situ hybridization, immunohistochemistry, and biochemical studies. In response to chronic low doses of UVB there was an initial moderate increase in tropoelastin mRNA in the papillary dermis. By contrast, there was a continuous marked elevation of collagen alpha1(I) message localizing to sites of inflammatory cell influx throughout the upper and lower dermis. After 25 wk of UV irradiation there was a 2-fold increase in skin elastin, yet total collagen remained unchanged. Serial desmosine analysis from en face sections indicated the increase in elastin content was due to dermal elastic fibers, an increase in the size and number of the dermal cysts, and an increase in subpanniculus elastic fibers. Elastin stains of en face sections suggested that the elastic fibers in the upper dermis were exclusively derived from cells lining the epithelial root sheath and sebaceous glands. In response to UV irradiation, the elastic fibers increased in number and size, wrapping around these structures and aligning in both directions as long fibers parallel to the body axis. Electron micrographs indicated that modified epithelial cells in close proximity to the flattened epithelial cells that encircled the root sheath and sebaceous glands were the source of the elastic fibers. (+info)Highly persistent label-retaining cells in the hair follicles of mice and their fate following induction of anagen. (7/1203)
We have identified some unusually persistent label-retaining cells in the hair follicles of mice, and have investigated their role in hair growth. Three-dimensional reconstruction of dorsal underfur follicles from serial sections made 14 mo after complete labeling of epidermis and hair follicles in neonatal mice disclosed the presence of highly persistent label-retaining cells associated with the first-generation follicle involved in the production of the first wave of hairs, commonly called the bulge. The label-retaining cells were most often found on the ventral surface of the first-generation follicle, five cell positions from the base, near the attachment site of the arrector pilorum muscle. No label-retaining cells were found in the hair canal, sebaceous gland, or hair germ. These label-retaining cells remained in the follicle following induction of anagen by plucking of the hairs. Surprisingly, they were not part of the first wave of mitotic activity following plucking, but instead underwent mitosis beginning 42 h after plucking. Label-retaining cells or their labeled daughters were not found in the hair germs through 48 h following induction of anagen by plucking, but instead remained in their subsebaceous follicular location even upon completion of the hair growth cycle 21 d later. These label-retaining cells are, therefore, unlikely to contribute to the formation of a new anagen follicle. (+info)A rapid and dynamic regulation of GDNF-family ligands and receptors correlate with the developmental dependency of cutaneous sensory innervation. (8/1203)
Glial cell line-derived neurotrophic factor (GDNF) and neurturin (NTN) are members of the transforming growth factor-beta family and have been shown to elicit neurotrophic effects upon several classes of neurons including dopaminergic neurons, motoneurons, parasympathetic, sympathetic as well as primary sensory neurons. However, there is little information available on their roles in cutaneous innervation. Herein, we have studied the regulation of gdnf, ntn and the GDNF family receptors and examined their role in the development of facial cutaneous innervation in GDNF mutant mice. A dynamic spatial and temporal regulation of gdnf, ntn and their ligand binding receptors within the follicle-sinus complex correlate with development of distinct subclasses of sensory nerve endings. Furthermore, development of NGF-dependent myelinated mechanoreceptors, i.e. reticular and transverse lanceolate endings also require GDNF during ending formation and maintenance. In addition, ligand and receptor association seems to be intricately linked to a local Schwann cell-axon interaction essential for sensory terminal formation. Our results suggests that functionally specified nerve endings depend on different GDNF family members and that in contrast to neurotrophins, this family of neurotrophic factors may be acting at local sites of terminal Schwann cell-axon growth cone interactions and that they collaborate with neurotrophins by supporting the same populations of neurons but at different times in development. (+info)1. Alopecia areata: This is an autoimmune disorder that causes patchy hair loss on the scalp or body.
2. Androgenetic alopecia (male pattern baldness): This is a common condition in which men experience hair loss due to hormonal changes.
3. Telogen effluvium: This is a condition where there is an increase in the number of hair follicles that stop growing and enter the resting phase, leading to excessive hair shedding.
4. Alopecia totalis: This is a condition where all hair on the scalp is lost, including eyebrows and lashes.
5. Alopecia universalis: This is a condition where all body hair is lost.
Alopecia can be caused by a variety of factors, including genetics, hormonal imbalances, autoimmune disorders, and certain medications. Treatment options for alopecia depend on the underlying cause and may include medications, hair transplantation, or other therapies.
In medical literature, alopecia is often used as a term to describe the loss of hair in specific contexts, such as in the treatment of cancer patients or in the management of autoimmune disorders. It is also used to describe the side effects of certain medications, such as chemotherapy drugs that can cause hair loss.
1. Alopecia areata: This is a condition where patches of hair fall out, resulting in bald spots on the scalp or other parts of the body.
2. Androgenetic alopecia: This is the most common form of hair loss, also known as male pattern baldness or female pattern baldness. It occurs when hormones cause hair to thin and fall out, leading to a receding hairline in men and a gradual thinning of hair on the top of the head in women.
3. Telogen effluvium: This is a condition where there is a sudden increase in the number of hair follicles that stop growing and enter the resting phase, leading to excessive hair shedding.
4. Trichotillomania: This is a psychological disorder characterized by an irresistible urge to pull out one's own hair, often resulting in noticeable hair loss.
5. Lichen planus: This is a skin condition that can cause hair loss, as well as itching and inflammation on the scalp.
6. Tinea capitis: This is a fungal infection of the scalp that can cause hair loss and inflammation.
7. Folliculitis: This is an inflammation of the hair follicles, which can cause hair loss and scarring.
8. Traction alopecia: This is a condition where hair loss occurs due to constant pulling or tugging on the hair, such as with tight hairstyles like braids or ponytails.
9. Chemical damage: Exposure to harsh chemicals in hair products can damage the hair and lead to hair loss.
10. Hair thinning: This is a condition where hair becomes thinner over time, often due to hormonal imbalances or nutritional deficiencies.
These are just a few examples of hair diseases that can affect people. It's important to note that many of these conditions can be treated with medical care and changes to one's lifestyle and diet. If you suspect you have a hair disease, it's important to consult a dermatologist or other qualified healthcare professional for proper diagnosis and treatment.
There are several types of alopecia areata, including:
1. Alopecia areata patchy - This is the most common form of the disease, where hair loss occurs in patches on the scalp or other parts of the body.
2. Alopecia totalis - Hair loss occurs over the entire scalp.
3. Alopecia universalis - Hair loss occurs over the entire body, including the scalp, eyebrows, and eyelashes.
4. Alopecia areata barbae - Hair loss occurs in the beard area.
5. Alopecia areata traction - Hair loss occurs due to pulling or tension on the hair shaft, often seen in children who pull their own hair.
The symptoms of alopecia areata may include:
1. Patchy hair loss
2. Thinning of hair
3. Redness and scalp inflammation
4. Itching or burning sensation on the scalp
5. Nail changes such as ridging, thinning, or pitting
Alopecia areata can be diagnosed through a physical examination and medical history. A skin scraping or biopsy may be performed to confirm the diagnosis.
Treatment for alopecia areata depends on the severity and location of hair loss, as well as the individual's overall health. Options may include:
1. Topical corticosteroids - Medicated creams or ointments applied directly to the affected area to reduce inflammation and promote hair growth.
2. Oral corticosteroids - Medications taken by mouth to reduce inflammation and suppress the immune system.
3. Anthralin - A medication that is applied to the skin to reduce inflammation and promote hair growth.
4. Immunotherapy - Injections or tablets that stimulate the immune system to attack cancer cells, but also can cause hair loss.
5. Wigs, hats, or other hairpieces - Used to cover up patchy hair loss.
6. Counseling or therapy - To help cope with the emotional impact of hair loss.
7. Hair transplantation - A surgical procedure that involves moving healthy hair follicles from one part of the scalp to another.
It is important to note that these treatments may not work for everyone and may have side effects. It's important to talk to a doctor or dermatologist to determine the best course of treatment for alopecia areata.
In addition to medical treatment, there are also some natural remedies that can help with alopecia areata such as:
1. Diet and nutrition - Eating a balanced diet rich in vitamins and minerals can promote hair growth.
2. Stress management - High stress levels have been linked to alopecia areata, so finding ways to manage stress, such as through exercise or meditation, may help.
3. Saw palmetto - A herb that has been shown to promote hair growth and slow down hair loss.
4. Fish oil - Omega-3 fatty acids found in fish oil have been shown to promote hair growth.
5. Coconut oil - Applying coconut oil to the scalp may help to stimulate hair growth.
6. Henna - A natural dye that can be used to color and strengthen hair, and may also help to promote hair growth.
7. Rosemary essential oil - May help to promote hair growth by increasing blood flow to the scalp.
8. Lavender essential oil - May help to reduce stress and promote relaxation, which can help with alopecia areata.
There are several types of hypotrichosis, including:
1. Congenital hypotrichosis: This type is present at birth and is caused by genetic mutations.
2. Acquired hypotrichosis: This type can develop later in life due to various factors such as hormonal imbalances, nutritional deficiencies, or certain medical conditions like thyroid disorders or anemia.
3. Localized hypotrichosis: This type affects only a specific area of the body, such as the scalp or eyebrows.
4. Generalized hypotrichosis: This type affects the entire body.
Hypotrichosis can have a significant impact on an individual's self-esteem and quality of life, especially if it results in noticeable hair loss or thinning. Treatment options for hypotrichosis include medications such as minoxidil (Rogaine) and finasteride (Propecia), as well as non-medical treatments like hair transplantation and low-level laser therapy (LLLT). In some cases, hypotrichosis may be a sign of an underlying medical condition, so it is important to consult with a healthcare professional for proper diagnosis and treatment.
Some common types of skin abnormalities include:
1. Birthmarks: These are benign growths that can be present at birth or appear later in life. They can be flat or raised, and can be made up of different types of cells, such as blood vessels or pigment-producing cells.
2. Moles: These are small, dark spots on the skin that are usually benign but can occasionally become cancerous.
3. Warts: These are small, rough bumps on the skin that are caused by the human papillomavirus (HPV).
4. Psoriasis: This is a chronic condition that causes red, scaly patches on the skin.
5. Eczema: This is a chronic condition that causes dry, itchy skin and can lead to inflammation and skin thickening.
6. Acne: This is a common condition that causes blackheads, whiteheads, and other types of blemishes on the skin.
7. Scars: These are areas of damaged skin that can be caused by injury, surgery, or infection.
8. Vitiligo: This is a condition in which the skin loses its pigment, leading to white patches.
9. Impetigo: This is a bacterial infection that causes red sores on the skin.
10. Molluscum contagiosum: This is a viral infection that causes small, painless bumps on the skin.
Skin abnormalities can be diagnosed through a combination of physical examination, medical history, and diagnostic tests such as biopsies or imaging studies. Treatment options vary depending on the specific type of abnormality and its underlying cause, but may include topical creams or ointments, medications, laser therapy, or surgery. It is important to seek medical attention if you notice any changes in your skin, as early diagnosis and treatment can help prevent complications and improve outcomes.
The exact cause of follicular cysts is not known, but they may be related to hormonal changes, genetic factors, or blockages within the hair follicle. Treatment options include observation, antibiotics, and surgical removal if the cyst becomes inflamed or infected.
A Follicular Cyst is a benign cystic lesion that forms in the scalp or face and typically arises from the hair follicle. They are usually small, soft to the touch, and painless unless they become inflamed or infected.
Follicular cysts are more common in women than men, and often appear during childhood or adolescence. Although their exact cause is unknown, they may be related to hormonal changes, genetic factors, or blockages within the hair follicle.
Small, soft, painless cysts that form on the scalp or face are usually Follicular Cysts, which are benign and do not produce any symptoms unless they become inflamed or infected. They appear more frequently in women than men and often develop during childhood or adolescence. Their exact cause is unknown but may be related to hormonal fluctuations, genetic factors, or blockages within the hair follicle.
The symptoms of hypertrichosis can vary in severity and may include:
* Excessive hair growth on the face, arms, legs, and torso
* Thick, coarse hair that is often curly or wavy
* Hair growing on the palms of the hands and soles of the feet
* Hair growing in the ears, nose, and mouth
* Increased risk of ingrown hairs and skin infections
There are several types of hypertrichosis, including:
* Generalized hypertrichosis, which affects the entire body
* Localized hypertrichosis, which affects specific areas of the body
* Congenital hypertrichosis, which is present at birth
* Acquired hypertrichosis, which develops later in life due to hormonal imbalances or other medical conditions.
Hypertrichosis can be challenging to diagnose, as it can be mistaken for other skin conditions such as acne or eczema. A proper diagnosis is usually made through a combination of physical examination, medical history, and genetic testing.
There is no cure for hypertrichosis, but there are several treatment options available to manage the symptoms. These may include:
* Medications such as anti-androgens and retinoids to reduce hair growth
* Electrolysis or laser hair removal to remove excessive hair
* Skincare and grooming techniques to prevent ingrown hairs and reduce the risk of skin infections.
It's important to note that hypertrichosis is a rare condition, and it can have a significant impact on an individual's quality of life. It can cause emotional distress, social stigma, and difficulties with employment and relationships. Therefore, it is essential to seek medical attention if symptoms persist or worsen over time.
There are several types of skin neoplasms, including:
1. Basal cell carcinoma (BCC): This is the most common type of skin cancer, and it usually appears as a small, fleshy bump or a flat, scaly patch. BCC is highly treatable, but if left untreated, it can grow and invade surrounding tissue.
2. Squamous cell carcinoma (SCC): This type of skin cancer is less common than BCC but more aggressive. It typically appears as a firm, flat, or raised bump on sun-exposed areas. SCC can spread to other parts of the body if left untreated.
3. Melanoma: This is the most serious type of skin cancer, accounting for only 1% of all skin neoplasms but responsible for the majority of skin cancer deaths. Melanoma can appear as a new or changing mole, and it's essential to recognize the ABCDE signs (Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolving size, shape, or color) to detect it early.
4. Sebaceous gland carcinoma: This rare type of skin cancer originates in the oil-producing glands of the skin and can appear as a firm, painless nodule on the forehead, nose, or other oily areas.
5. Merkel cell carcinoma: This is a rare and aggressive skin cancer that typically appears as a firm, shiny bump on the skin. It's more common in older adults and those with a history of sun exposure.
6. Cutaneous lymphoma: This type of cancer affects the immune system and can appear as a rash, nodules, or tumors on the skin.
7. Kaposi sarcoma: This is a rare type of skin cancer that affects people with weakened immune systems, such as those with HIV/AIDS. It typically appears as a flat, red or purple lesion on the skin.
While skin cancers are generally curable when detected early, it's important to be aware of your skin and notice any changes or unusual spots, especially if you have a history of sun exposure or other risk factors. If you suspect anything suspicious, see a dermatologist for an evaluation and potential biopsy. Remember, prevention is key to avoiding the harmful effects of UV radiation and reducing your risk of developing skin cancer.
Pilomatricoma is thought to arise from the abnormal growth and development of matrical cells, which are responsible for producing the protein components of the hair follicle. The tumor typically does not grow or change over time, and is usually asymptomatic unless it becomes infected or irritated.
Pilomatricoma is relatively rare, accounting for less than 1% of all skin tumors. It is most commonly seen in adults between the ages of 20 and 50, although it can occur at any age. The exact cause of pilomatricoma is not known, but it may be associated with genetic mutations or environmental factors that affect the development of hair follicles.
There are several methods for diagnosing pilomatricoma, including:
* Clinical examination: A healthcare provider will typically examine the tumor and surrounding skin to determine its size, shape, color, and texture.
* Biopsy: A small sample of tissue from the tumor may be removed and examined under a microscope to confirm the diagnosis.
* Imaging studies: CT or MRI scans may be used to evaluate the size and extent of the tumor, as well as any potential involvement of surrounding structures.
Treatment for pilomatricoma usually involves surgical excision of the tumor, although in some cases, observation or laser therapy may be appropriate. The prognosis for pilomatricoma is generally excellent, as it is a benign condition that does not spread to other parts of the body (metastasize). However, if the tumor becomes infected or irritated, complications such as abscesses or scarring may occur.
In summary, pilomatrixoma is a rare, benign skin tumor that arises from matrical cells in the hair follicle. It typically presents as a slow-growing, flesh-colored or pink nodule on the face, neck, or scalp. Diagnosis is based on clinical examination and imaging studies, and treatment involves surgical excision or observation. The prognosis is generally excellent, but complications can occur if the tumor becomes infected or irritated.
BCC usually appears as a flesh-colored or pink bump, often with small blood vessels on the surface. It may also be flat and scaly, or have a waxy appearance. In rare cases, BCC can grow deep into the skin and cause damage to surrounding tissue.
Although BCC is not as aggressive as other types of skin cancer, such as melanoma, it can still cause significant damage if left untreated. Treatment options for BCC include topical creams, surgical excision, and Mohs microscopic surgery.
Preventative measures against BCC include protecting the skin from the sun, using sunscreen with a high SPF, and avoiding prolonged exposure to UV radiation. Early detection and treatment are key in managing this condition.
If left untreated, folliculitis can lead to more serious infections such as boils or abscesses, which may require surgical drainage. It is also possible for folliculitis to cause scarring and permanent hair loss if the inflammation damages the hair follicle.
While anyone can develop folliculitis, it is more common in people with oily skin or those who wear tight clothing or heavy makeup that can clog pores and irritate the skin. Additionally, certain medical conditions such as diabetes, HIV/AIDS, and cancer can increase the risk of developing folliculitis.
Folliculitis is usually diagnosed through a physical examination and may require a biopsy to rule out other skin conditions. Treatment options for folliculitis depend on the severity and cause of the condition, but may include antibiotics, topical creams, or oral medications. It is important to seek medical attention if symptoms persist or worsen over time, as early treatment can help prevent complications and improve outcomes.
