Paronychia and subungual abscesses

Introduction to paronychia and subabdominal abscess In addition to the free edge of the nail and the subarachnoid abscess, the other three sides are connected with the skin folds, and the joint forms a groove, called the sulcus (Fig. 1). The paronychia is the infection in the sulcus. A subabdominal abscess is an infection between the nail and the nail bed. Both can be converted or exist at the same time. basic knowledge The proportion of illness: 0.06% Susceptible people: no special people Mode of infection: non-infectious Complications: purulent finger inflammation osteomyelitis

The cause of paronychia and subabdominal abscess

(1) Causes of the disease

A sulcus inflammation is caused by stab wounds, bruises, ingrown toenails or pull-outs of prickly thorns. The sub-abscess is often spread by paronychia, or an infection caused by a stab wound, or The end of the crush injury caused a secondary hematoma secondary infection, the pathogen is mainly Staphylococcus aureus.

Paronychia and sub-abscess prevention

1, usually love the skin around the nails, do not cause any damage, the nails should not be cut too short, but also can not pull the "barbs" by hand.

2, prevent problems before they happen. Wood thorns, bamboo thorns, sewing needles, fish bone spurs, etc. are the most foreign objects in daily life that can easily stab the sulcus. When you are working or busy with housework, you should be extra careful.

3, usually pay attention to the maintenance of the fingers, after washing hands, wipe a little Vaseline or skin care cream before going to bed, can enhance the disease resistance of the skin around the nail groove.

4, when there are minor injuries to the fingers, you can rub 2% iodine, then bandage with band-aid to prevent infection.

5, early stage of paronychia can be used for hot compress, physiotherapy, external application of Jiagou Kang, if necessary, take sulfa drugs or antibiotics.

6, if you have suppuration, you should go to the hospital to cut in time, drain the pus. Preventing the spread of infection and causing osteomyelitis

7, if the underlying empyema, the nail should be pulled out, in order to facilitate adequate drainage and complete cure.

Complications of paronychia and subabdominal abscess Complications purulent finger inflammation osteomyelitis

May be associated with purulent finger inflammation or phalange osteomyelitis.

Paronychia and subabdominal abscess symptoms Common symptoms Abscess

At the beginning, the side of the nail is red and swollen, painful, and can be purulent in a short time. The infection can spread to the nail root and the contralateral sulcus, forming inflammation around the nail, and can also spread to the underarm, forming a subabdominal abscess. Intensified, swelling is obvious, yellow white pus can be seen under the nails, and the nails will be floated. If not treated in time, it can develop into purulent finger inflammation, and even cause osteomyelitis of the phalanx, which can also become chronic paronychia. The more, the paronychia or the subabdominal abscess, because the infection is superficial, the systemic symptoms are often not obvious.

Examination of paronychia and subabdominal abscess

Sometimes white blood cells can rise.

X-ray examination, no positive findings.

Diagnosis and differentiation of paronychia and subabdominal abscess

Based on medical history and clinical manifestations, laboratory tests are generally not difficult.

1. Shallow part: Abscess manifests as local redness, swelling, heat, pain and tenderness, and then fluctuates.

2. Deep: The abscess is a local diffuse swelling, pain and tenderness, and the fluctuation is not obvious. The puncture can be taken out by the test puncture, and it can also be used as an ultrasound consultation.
