To report 3 cases of acute generalized exanthematous pustulosis (AGEP) caused by hydroxychloroquine. All the 3 patients were females, aged 23, 30, and 28 years respectively. In cases 1 and 3, the rashes appeared 4 days and 12 days respectively after the treatment with hydroxychloroquine for systemic lupus erythematosus; case 2, who was 8 weeks pregnant, developed rashes 10 days after starting hydroxychloroquine treatment for antiphospholipid syndrome. All the 3 patients had high fever, and clinically presented with generalized round or oval-shaped edematous erythema on the face, neck, trunk and limbs, covered with a large number of pinhead-sized pustules, and with multiple erythema multiforme-like lesions on the trunk and both upper limbs, including targetoid lesions. Mutations in the IL36RN gene were identified in all the 3 patients: a homozygous mutation c.115+6T>C in the IL36RN gene was found in case 1, and her parents were heterozygous carriers; case 2 inherited the heterozygous mutation c.115+6T>C in the IL36RN gene from her mother; the heterozygous mutation c.115+6T>C found in case 3 was a de novo mutation. A diagnosis of AGEP was made in all the 3 cases. Cases 1 and 2 received subcutaneous injections of adalimumab in addition to the treatment of their underlying diseases, and skin lesions markedly regressed after 1 week of treatment; case 3 was treated with high-dose glucocorticoids, and lesions subsided after 4 weeks; no significant adverse reactions were observed in cases 1 and 2, however, femoral head necrosis was noted in case 3. During a follow-up period of 42 months, none of the patients experienced recurrence, and case 2 gave birth to a healthy baby boy after 8-month treatment.

Objective:To report a case of hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis (POIKTMP), and analyze the genotype-phenotype correlation through a literature review.Methods:The clinical manifestations and genetic testing results of a Chinese Han child with POIKTMP were reported. Relevant literature was searched in databases using ′FAM111B gene′, ′hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis′ or ′POIKTMP′ as keywords, and the clinical manifestations, mutation sites of the FAM111B gene, and the correlation between them were statistically analyzed.Results:A 6.5-year-old girl developed POIKTMP at 6 months of age. Dermatological examination showed irregular brown patches and dotted hypopigmentation on the face and neck, mainly on the forehead and around the mouth, telangiectasia on the cheeks and nose, pigmentation and hypopigmentation on the limbs and trunk, as well as sparse, pale eyebrows. A total of 39 cases of POIKTMP were retrieved, including this case, all of which had clinical data and were definitively diagnosed. Fourteen variants of the FAM111B gene had been reported, including 1 in-frame deletion variant and 13 missense variants. Among the 39 cases, the incidence of poikiloderma/photosensitivity/facial erythema/telangiectasia was 100% (39/39), alopecia was 87.2% (34/39), and that of hypohidrosis/heat intolerance was 82.1% (32/39). The incidence of extracutaneous manifestations was as follows: tendon contractures/digital sclerosis, 69.2% (27/39) ; elevated liver transaminases, 46.2% (18/39) ; muscle pain/weakness/amyotrophy, 43.6% (17/39). The incidence of eczema-like lesions, bullous lesions, and elevated liver transaminases was significantly higher in the young versus the adult group ( P < 0.05) . Conclusions:This case of POIKTMP was characterized by brown patches, hypopigmentation, and sparse eyebrows. POIKTMP is a progressive multisystem disorder with age-related clinical manifestations. Early genetic testing is crucial for evaluating potential complications and providing genetic counseling.

Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2011 to 2019, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of mumps in Guangxi from 2011 to 2019. Results From 2011 to 2019, a total of 146,132 cases of mumps were reported in Guangxi, with an average annual incidence rate of 34.23 /100 000. There were 88,919 male cases (60.85%) and 57,213 female cases (39.15%). The incidence rate decreased from 62.26/100 000 in 2011 to 16.46/100 000 in 2015, and increased from 18.60/100 000 in 2016 to 46.90/100 000 in 2019. There were seasonal variations in the incidence, with the incidence peaks occurring from April to July and from October to the following January. 85.39% of cases were under 15 years of age, and 76.82% of cases were among kindergarteners or school children. A total of 228 mumps outbreaks were reported during 2011-2019，including 5,347 cases, accounting for 3.66% of the total cases. The incidence rates of mumps in Nanning (56.09/100 000), Hechi (48.26/100 000), Liuzhou (46.77/100 000), Baise (46.34/100 000) and Fangchenggang (40.68/100,000) were relatively higher than other places. Conclusion The mumps incidence is on an upward trend in Guangxi since 2015-2019, occurring mainly in older children or students. It is suggested to adhere to the second dose of mumps containing vaccine for kindergarten and school children and strengthen the surveillance and outbreak control of mumps in schools.
