Bacteriological study, including antibiotic sensitivity tests, of 81 patients with pyodermas such as impetigo, folliculitis, furuncle, carbuncle, cellulitis and acuete infectious eczematoid dermatitis, was carried out during 4 months period from June, 1980 to September, 1980 at the department of dermatology, Han Il Hospital. The results were as follows: 1) The causative agents of impetigo in 42 patients, were coagulase positive Staphylacoccus aureus in 33, p-hemolytic Streptococcus in 6 and both organisms in R (S. aureus and 3-hemolytic Streptococcus). Coagulase negative Stgaphylococcus was not found. 2) The causative agents of superficial and deep follicultis in 23 cases, were coagulase positive S. aureus in 12, coaulase negative Staphylococcus in 5, p-hemolytic Streptococcus in 4 and S. aureus and p-hemolytic Streptococcus in 3. 3) The causative agents of cellulitis in 2 cases, were coagulase positive S. aureus in 1, and coagulase negative Staphylococcus in 1. 4) The causative agents of acute infectious eczematoid dermatitis in l4 cases, were coagulase positive S. aureus in 6, coagulase negative Staphylococcua in 1, p-hemolytic Streptococcus in 2, and two organisms in 5 (4 cases were mixed).

OBJECTIVE: To analyze the composition, incidence and clinical characteristics of oral and maxillofacial infections in oral emergency. METHODS: A retrospective study on patients with oral and maxillofacial infections who visited the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2017 to December 2019 was conducted. General characteristics, such as disease composition, gender, age distribution and position of involved teeth were analyzed. RESULTS: A total of 8 277 patients with oral and maxillofacial infections were finally collected, including 4 378 male patients (52.9%) and 3 899 female patients (47.1%), with gender ratio of 1.12:1. The common diseases were periodontal abscess (3 826 cases, 46.2%), alveolar abscess (3 537 cases, 42.7%), maxillofacial space infection (740 cases, 9.0%), sialadenitis (108 cases, 1.3%), furuncle & carbuncle (56 cases, 0.7%) and osteomyelitis (10 cases, 0.1%). Male patients were more easily affected by periodontal abscess, space infection and furuncle & carbuncle than female patients with the gender ratios 1.24:1, 1.26:1, 2.50:1 individually, while the incidence of alveolar abscess, sialadenitis, furuncle & carbuncle had no significant gender difference. Different diseases were prone to occur at different ages. The peak ages of alveolar abscess were 5-9 and 27-67 years, while the peak age of periodontal abscess was 30-64 years. Space infection tended to occur between 21-67 years. There were 7 363 patients with oral abscess (3 826 patients with periodontal abscess and 3 537 patients with alveolar abscess), accounting for 88.9% of all the patients with oral and maxillofacial infections, involving 7 999 teeth, including 717 deciduous teeth and 7 282 permanent teeth. Periodontal abscess usually occurred in permanent teeth, especially the molar teeth. Alveolar abscess may occur in both primary teeth and permanent teeth. In primary teeth, the most vulnerable sites were primary molar teeth and maxillary central incisors while in permanent teeth the most vulnerable sites were first molar teeth. CONCLUSION Understanding the incidence of oral and maxillofacial infection was conducive to the correct diagnosis and effective treatment of clinical diseases, as well as targeted education for patients of different ages and genders to prevent the occurrence of diseases.

Subdural empyema is a neurosurgical emergency the mortality of which continues to be as high as 40% in modern reported series. It is also a curable lesion, and the outcome of treatment has been demonstrated to be directly related to the promptness of diagnosis and appropriate surgical drainage. Recently, we have operated upon two cases of intracranial subdural empyema secondary to acute facial furuncle and postoperative craniectomy. Reviewing these two cases and other literatures, we are going to describe about cases, symptoms and signs, and methods of diagnosis and treatment of subdural empyema.

BACKGROUND: Bacterial infections of the skin are treatable and reversible, so clinicians should be alert for the cutaneous signs of the skin infection. However, there have been only a few reports about the epidemiology of skin infections. OBJECTIVE: This study was done to evaluate the trend of the clinical features, the results of cultures and the prevalence of MRSA in the dermatology outpatients who had suspected bacterial skin infection in 1996, 2001 and 2006 and we wanted to compare the trends of bacterial skin infection over the last eleven years. METHODS: The survey was conducted via the medical records of 24 patients in 1996, 77 patients in 2001 and 88 patients in 2006 who visited the our dermatology department and who underwent Gram-stain and bacterial culture. RESULTS: Of the 347 samples, bacteria were cultured in 197 samples. Among them, 77 samples had coagulase negative Staphylococci, which were excluded as normal skin flora. Among 120 samples, the number of cases of secondary pyoderma, folliculitis, furuncle or carbuncle and cellulitis were 63, 17, 17 and 15, respectively. There was no change in the type of diagnosis during eleven years. The most common pathogen of skin infection was S. aureus (42.7%) and there was no trend to increase for ten years. However, the prevalence of methicillin resistant S. aureus (MRSA) increased for eleven years. CONCLUSION: The most common pathogen in pyogenic skin infections of the dermatology outpatients was S. aureus, which was sensitive to beta-lactamase resistant beta-lactam antibiotics, but there was an increase of the prevalence of MRSA for eleven years, and the first therapeutic choice for MRSA is vancomycin or teicoplanin.

Staphylococcus aureus is one of many causative agents of the fu uncles. As the S. aureus strains resistant to penicillinase-repsistant penicillins (methicillin-resistant S. aureus, MRSA) are more frequently isolated, their accuiate identification became a very important step in selection of an appropriate therapeutic regimen. We report herein a case of multiple furunculosis caused by metkicillin-resistant S. aureus in a 11-year-old male patient, who was successfully treated with sulbactam/ampicillin and amikacin.

Cutaneous lesions of Behcet's disease are varied and include papulopustular lesions, erythema nodosum-like lesions, superficial thrombophlebitis, erythema multiforme-like lesions, Sweet's syndrome-like lesions, furuncles, pyoderma gangrenosum and subungal infarctions. Papulopustular lesions, the most common presentation of skin lesions in Behcet's disese, are cutaneous, sterile folliculitis or acne-like lesions on an erythematous base. Disagreement exists as to the exact nature of these acneiform and folliculitis-like lesions and whether they should be included as a major criteria. We report a case of papulopustular lesions in Behcet's disease which developed in a 41-year-old male.

Kerion celsi is an inflammatory infection, caused by a vigorous T-cell mediated host response to the dermatophyte infection. In the case of severe inflammation, it can be misdiagnosed as other disease like cellulitis, impetigo, furuncle and epidermal cyst. Microsporum(M.) canis is most likely transmitted by contact of animal hosts such as cats and dogs with humans. We report the 75-year-old female who presented two months history of tender erythematous scaly plaques with pustules, crusts on right scalp area. At first, from the histopathologic findings of the lesion, the patient was diagnosed epidermal cyst because of cyst-like structure in mid-dermis. But the fungal culture revealed M. canis as the causative fungus. Herein we report a educational case of kerion celsi mistaken for ruptured epidermal cyst.

Tinea incognito is a dermatophytosis of atypical clinical character due to the absence of classic features of ringworm. It is caused by prolonged use of topical or systemic corticosteroids, sometimes prescribed as a result of incorrect diagnosis. We report a case of tinea incognito presented like furunculosis on the chin. The patient had been treated with topical and oral corticosteroid under the impression of atopic dermatitis for 3 years for the eczematous lesion on the face and trunk. Mycologic studies including KOH mount and fungus culture were positive for hyphae and colonies of Trichophyton rubrum. Skin biopsy showed fungal hyphae in follicular keratinous plug and diffuse dermal and perifollicular inflammation. The lesion was treated with terbinafine systemically and cured 3 months later.
