Desquamative Gingivitis as the First Clinical Sign of Pemphigus Vulgaris: A Case Report

ABSTRACT@#Desquamative gingivitis is characterised by desquamation of the gingiva with painful erosion and ulceration. It is predominantly a manifestation of several vesiculobullous diseases. Delayed diagnosis or misdiagnosis often led to disease progression. Pemphigus vulgaris is a chronic, life-threatening autoimmune disease resulting in blistering of the mucosa and skin. Oral lesions normally preceded skin lesions. Early diagnosis and treatment are important to prevent involvement of the skin, as the treatment and prognosis varies with extraoral involvement. Clinical, histopathological examination and direct immunofluorescent are necessary for the diagnosis of pemphigus vulgaris. Treatment of desquamative gingivitis involves improving oral hygiene, reduce irritation to the lesions and specific therapy to the underlying disease. This paper describes a case of a patient with desquamative gingivitis for one year, whom is ultimately diagnosed as having pemphigus vulgaris.

Analysis of etiological agent in 771 children with lower respiratory infection / 国际儿科学杂志

Objective To detect and analyze viral pathogens and the etiological agent distribution of hospitalized children with lower respiratory infection. Methods We adopted direct immunofluorescence to detect the seven frequent respirovirus antigens from nasopharyngeal secretion in 771 hospitalized patients with lower respiratory infection.Results Virus detection of 243 cases was positive in 771, the total positives ratio was 31.52%. Respirovirus infection had obviously relation with age and season. The positive rate of virus infection was highest in asthma, followed in bronchiolilis and asthmatic bronchitis, which were 58.80% and 35.56% respectively. Conclusion Different ages and different seasons presented different viral infection and different virus types. Infection rate in infant was higher obviously than that in the other ages, respiratovy syncytial virus and parain- fluenza virus were the major virus in lower respiratory infection. Viral infection was important reason to cause children asthma.

Immunofluorescent Studies of Various Chronic Bullous Dermatoses / 대한피부과학회지

The accuracy and sensitivity of both direct and indirect immunofluorescence microseopy in diagnosing chronic bullous dermatoses were evaluated and compared in 11 cases of six different disease entities(pemphigus vulgaris, pemphigus vegetans, bullous pemphigoid, linear IgA bullous dermatosis, familial benign chronic pemphigus), which had been diagnosed clinically and by routine histopa thological studies. And the results obtained were as follows: 1) In 4 cases of bullous pemphigod, the direct IF of perilesional skin showed linear deposition of IgG and C2 along basement membrane zone(BMZ), whereas the indirect IF revealed negetive findings. 2) In 2 cases of pemphigus vulgaris, the direct IF showed deposition of IgG and C2 in intercellular substance(ICS) of perilesional epidermal tissue, and the indirect IF revealed auto-antibody to ICS(1:320) in one case. 3) In 2 cases of linear IgA bullous dermatosis, which were diagnosed as dermatitis herpetiformis by clinical and routine hisopathological findings, the direct IF of perilesional and uninvolved skin manifested linear deposition of IgA, IgM, C3 and F along BMZ, However, no immunofluorescence was detected by the indirect IF. 4) In a case of chronic bullous dermatosis of childhood, the direct IF of perilesional skin showed linear deplosition of IgA and IgM along BMZ. 5) In a case of pemphigus vegetans, the direct IF revealed no specific findings, while the inderect IF disclosed auto antibody positive to ICS(1:40). 6) In a case of familial benign chronic permphigus, no immunofluorescence was found by direct IF. These results indicate that both direct and indirect immunofluorescence micros-copy are valuable in diagnosing chronic bullous dermatoses and in understanding their immune pathogenesis.

Estimation of Alteration of Peripheral Blood Immune Cells in Patients with Plopecia Areata / 대한피부과학회지

Authors have quantitated the T cell and T subsets(T and T cell) in the per- ipheral blood of 16 patients with alopecia areata and 16 normal healthy controls. The results are as follows: 1. The mean values of the T cell in total patient group(54,6+7.9g) and AAP group(5,3. 1+8. 1%) showed staticstially significant decrease when it compared with the mean value of the control group(64.6+3.6%) respectively(p<0.005). In ATU group the mean value of the T cell(53. 1+8. 1%) also showed decreasing tendency in comparison with that of control. The mean values of the T cell in total patient group(30.9+8. 9%) RIld AAP group(3'l. 5+8. %) showed statistically significant decrease when it compared with the mean value of the control group(42,6+8.9%) respectively(p<0. 005). In ATU group the mean value of the T< cell(28. 7+10. 9%) also showed decreasing tende- ncy in comparison with that of control. 3. The mean values of the Tr, cell in total patient group(6. 1+2. 2%) and AAP group(5.9+2.4%) showed staticstially significant decrease when it compared with the mean value of the control group(7.9+1.3%) respectively(p(p pl, pgp p25) In ATU group the mean value of the T cell(6. 7+0. 9%) also showed decreasing tendency in comparison with that of control. 4. The mean values of the T/T ratio showed no significant difference between the patient groups(total, AAP, ATU) and control group, respectively. Above data showed that defect of T cell and T subsets may be associated with the pathogenesis of alopecia areata.
