Fungal paronychia

　　The symptoms of paronychia are often caused by wearing shoes that are too small or too tight, causing the forefoot to be compressed. When trimming the toenails, leaving sharp angles that grow into the soft tissue can lead to infected paronychia symptoms, causing paronychia symptoms with granulation tissue formation. Other causes, such as congenital abnormalities at the nail root, causing the nail margin to grow obliquely, can also lead to paronychia symptoms.

　　Paronychia usually does not present with systemic symptoms. If not incised and drained, the abscess can spread under the nail, forming an under-nail abscess. Yellowish pus can be seen under the nail, causing the nail to separate from the nail bed. Under-nail abscess can be caused by direct puncture injury to the nail or traumatic hematoma under the nail, leading to infection. If not treated promptly, it can become chronic paronychia or chronic osteomyelitis of the finger bone.

　　When fungal onychia starts, the subcutaneous tissue on one side of the nail becomes red and swollen and painful. Mild cases can regress, but if the infection is severe, it can quickly suppurate and spread to the nail root and the opposite nail fold. If it spreads under the nail, it can cause the nail to separate from the nail bed, and pus under the nail can be seen.

　　Choose appropriate shoes; do not cut the nail folds at will, and if the toes are pressed together, apply a suitable amount of disinfected cotton or soft material into the gaps between the toes to separate them, allowing the toes to develop normally, preventing the toes from being pressed into the nail folds; do not cut the nails too short; develop good hygiene habits, do not remove ingrown toenails at will; pay attention to the care of fingers in daily life, which can enhance the disease resistance of the skin around the nail folds, and these are health measures for preventing fungal onychia.

　　White blood cell count and differential count:In unilateral onychia, white blood cell count usually does not change significantly. After the formation of an abscess under the nail, due to the absorption of bacterial toxins, systemic symptoms of poisoning may appear, and the white blood cell count and neutrophils increase significantly.

　　Patients with fungal onychia should eat light, eat more fresh fruits and vegetables, reasonably match their diet, and ensure adequate nutrition. Eat less high-salt, high-sugar, high-fat,刺激性, and spicy foods.

　　Treatment of Fungal Onychia:Early treatment can include physical therapy, hot compresses, external application of ichthammol ointment or San Huang powder, and the use of antibiotics or iodamine drugs. For those with pus, a longitudinal incision can be made at the nail fold for drainage. When the infection has involved the subcutaneous tissue around the base of the finger nail, longitudinal incisions can be made on both sides of the nail fold, the epidermal sheet of the nail root can be flipped up, the nail root can be excised, and a small piece of gauze or latex sheet can be placed for drainage. If there is pus under the nail bed, the nail should be pulled out or the nail at the pus cavity should be cut off. When pulling out the nail, attention should be paid to avoid damaging the nail bed to prevent deformity of the newly grown nail in the future.
