Dermatomyositis is identified by a characteristic rash accompanying or, more commonly, preceding muscle weakness. Only 14% of cases occurs during child-bearing years, and only a few cases of dermatomyositis associated to pregnancy complications have been reported. Therefore there is relatively little information concerning the maternal and fetal outcome. The clinical diagnosis of dermatomyositis is confirmed by three laboratory examinations: serum muscle enzyme concentrations, electromyography, and muscle biopsy. Some authors suggest that the outlook for the fetus is unfavorable when dermatomyositis is first diagnosed during pregnancy. Others consider that fetal prognosis parallels the activity of maternal disease. Various factors have been considered as triggers for development of dermatomyositis during pregnancy. There is no report of maternal-to-fetal transmission of disease. We have experienced a case of dermatomyositis diagnosed at postpartum and then received a prompt management of the patient so presented this case with a brief review of the literatures.

We report a case of atypical pityriasis rosea in a 24-year-old Malay man. He presented with an 11-month history of three recurrent and persistent episodes of pityriasis rosea associated with oral ulcers. The first episode lasted for one month and recurred within 14 days. The second episode lasted for three months and recurred within nine days. The third episode lasted for seven months. Although all three episodes were not preceded by any prodromal symptoms, a herald patch was noted on three different sites (the left iliac fossa, abdomen and chest) on each successive episode. Recurrent pityriasis rosea and its association with oral ulcers, although quite uncommon, have been reported in the literature. However, reports of multiple recurrences, with prolonged duration of each episode and very short remissions in between, have not been made. To the best of our knowledge, this is the first report of such unique presentation.

Herbal remedies and health foods are widely used, and their side effects have been reported. We describe two cases of symptomatic toxic hepatitis that developed in middle-aged women after ingesting arrowroot juice. The clinical manifestations were nausea, vomiting, and jaundice. The diagnosis of toxic hepatitis was made using the Roussel Uclaf Causality Assessment Method score on the basis of the patient's history and laboratory data. After supportive care, the patients showed rapid improvements of clinical symptoms, laboratory findings, and liver stiffness. Clinicians should be aware that the consumption of arrowroot juice can cause toxic hepatitis.

The triad of rash, arthritis, and uveitis seems to be characteristic for early-onset childhood sarcoidosis. We describe an interesting case of early-onset childhood sarcoidosis coexisting enchondromatosis, which clinically masquerade as Langerhans cell histiocytosis. A 33 months old girl presented with skin rash, subcutaneous nodules with polyarthritis, and revealed the involvement of lymph nodes as well as spleen during work-up. She also presented with multiple osteolytic lesions which pathologically proven enchondromatosis. Oral prednisone was prescribed at 2 mg/kg/day for 2 months until when subcutaneous nodules and joint swellings almost disappeared, and then slowly tapered over a period of 5 months. We report an unusual case of early-onset childhood sarcoidosis presented with osteolytic bone lesions which were irrelevant to sarcoidosis.

OBJECTIVETo study the Chinese medicine (CM) syndrome laws of patients with pruritic papular eruption (PPE), thus providing reference for its classification and standard diagnosis.

METHODSUsing multicenter, prospective trials in 346 PPE patients,the correlations between sex, age, infection route, and CD4 levels and CM syndrome patterns were analyzed. The syndrome laws correlated with PPE was studied from the macroscopic and microscopic aspects.

RESULTSThere was no statistical difference in sex, age, or CD4 level among various CM syndrome patterns. There was statistical difference in the infection route among various CM syndrome patterns. Pi-deficiency dampness-accumulation syndrome occurred more in patients infected by blood. Wind production induced by heat in blood syndrome occurred more in those infected by sexual contact. Blood deficiency wind dryness syndrome occurred in those infected by intravenous drug abuse.

CONCLUSIONSWind production induced by heat in blood syndrome, blood deficiency wind dryness syndrome, and Pi-deficiency dampness-accumulation syndrome exist in CM syndrome types of AIDS. There was statistical difference in different infection routes of the distribution of each syndrome type.

OBJECTIVETo improve the recognition of the clinical presentation and radiologic manifestation of children with Langerhans cell histiocytosis (LCH) with pulmonary involvement.

METHODA retrospective analysis was conducted on children who presented with respiratory symptoms or abnormal lung radiologic findings, and finally diagnosed with LCH in Ward 2 of Divison of Respiratory Diseases, Beijing Children's Hospital during the last 4 years.

RESULTFourteen children (10 boys and 4 girls) were included in this study. Male to female ratio was 2.5: 1. The median age was 1.3 years. Pulmonary involvements were coexisted with other involved organs in all the patients, such as skin (10 cases, 71%), liver (8 cases, 57%), and bone involvement (7 cases, 50%). The most common symptoms were cough and fever (7 cases, 50%). Respiratory symptoms were nonspecific, and 3 children had no respiratory symptom but abnormal findings on lung high-resolution CT (HRCT). The most common HRCT finding was the coexistence of nodules and cysts (6 cases, 43%). Other findings include cysts only (5 cases, 36%), nodules only (1 case), and with neither nodule nor cyst (2 cases, 14%). Pneumothorax was found in 7% of children.

CONCLUSIONPulmonary involvement in children with LCH is easily misdiagnosed, and often coexisted with other involved tissues/organs such as skin and liver. Rash, which is easily missed in physical examination is very important for the diagnosis of LCH. The characteristic findings of lung HRCT (nodules and/or cysts) are helpful for diagnosis.

OBJECTIVEBlau syndrome (BS), an autosomal dominant inherited autoinflammatory disease, is caused by NOD2 mutations. This study aimed to analyze NOD2 gene of suspected BS patients to make definite diagnosis, find NOD2 mutation types and clinical features of Chinese BS cases, and find some clinical indications to identify BS by comparing BS and non-BS cases.

METHODEighteen suspected BS children (7 boys and 11 girls, age of first visit was from 1 y 8 m to 9 y 6 m) who visited Peking Union Medical College Hospital from 2006 to 2014 and their parents's DNA were extracted from 4 ml blood specimens. PCR was performed for exon 4 of NOD2 and PCR products were purified by 2% gel electrophoresis and sequenced directly. Role of novel missense mutations in pathogenicity was analyzed by SIFT and sequencing NOD 2 of fifty normal controls. Clinical data of BS children diagnosed by NOD2 analysis were summarized and compared with the data of non-BS group.

RESULT(1) Twelve of eighteen suspected BS children were diagnosed as BS by NOD2 analysis, and the remaining 6 were excluded. Seven missense mutations were detected, 4 were reported before: c.1000C>T, p. Arg 334Trp; c.1001G>A, p. Arg334Gln; c.1538T>C, p. Met513Thr; c.1759C>T, p. Arg587Cys. Three novel mutations were found: c. 1147 G>C, p.Glu383Gln; c.1471A>T, p. Met491Leu; c.2006A>G, p.His669Arg. (2) Chronic symmetric arthritis and multi-joints periarticular hydatoncus, which were painless with fluctuation, were found in all 12 BS children with NOD2 mutations. Skin rash, chronic symmetric arthritis, and recurrent uveitis were identified in 7 patients. Three patients had no skin rash, while 1 had no uveitis, 1 only had symmetric arthritis and multi-joints periarticular hydatoncus. Four children inherited the disease from father. (3) Compared with other 6 non-BS children, BS children had such different clinical characteristic (P < 0.05): All the BS cases had multiple periarticular hydatoncus, which always had no persistent fever, most had no elevated CRP, while non-BS group always had no hydatoncus, most had persistent fever, all had elevated CRP.

CONCLUSIONThe 12 BS children were diagnosed by NOD2 analysis; 7 missense mutations were detected, 3 were novel mutations, adding new findings to human NOD2 mutations. Although classic BS was characterized by skin rash, arthritis, and eye involvement, some presented with less than 3 of the classic features. Chronic symmetric arthritis and multi-joints periarticular hydatoncus were the most comment fetures. Comparing with non-BS group, all BS cases had multi hydatoncus surrounding multi-joints, always had no persistent fever, most had no elevated CRP. Those features may distinguish BS in clinical settings.

Hemophagocytic syndrome (HPS) is a severe disease characterized by excessive release of inflammatory cytokines caused by abnormal activation of lymphocytes and macrophages, which can cause multiple organ damage and even death. Panniculitis is a disease characterized by inflammation of subcutaneous adipose tissue. We effectively treated 2 patients with panniculitis-associated HPS with ruxolitinib. Case 1: A 70-year-old male started with intermittent plantar swelling and pain, and then developed leukocytosis, mild anemia, multiple red maculopapules with painless subcutaneous nodules on the forehead, neck and bilateral lower legs. The patient was treated with prednisone and leflunomide for improvement. After that, repeated fever and rash occurred again. After admission to our hospital, we found his leukocyte and hemoglobin decreased, ferritin raised, fibrinogen and natural killer (NK) cell activity decreased, and hemophagocytic cells were found in bone marrow aspiration. The skin pathology was consistent with non-suppurative nodular panniculitis. He was diagnosed with nodular panniculitis associa-ted HPS. He was treated with glucocorticoid, cyclosporine, etoposide and gamma globule, but the disease was not completely controlled. After adjusting etoposide to ruxolitinib, his symptoms and abnormal laboratory findings returned to normal. After 2 months he stopped using ruxolitinib due to repeated infections. During the follow-up, though the prednisone dose was tapered, his condition was stable. Case 2: A 46-year-old female patient developed from intermittent fever, erythematous nodular rash with tenderness, leukopenia, and abnormal liver function. antibiotic therapy was ineffective. She improved after glucocorticoid treatment, and relapsed after glucocorticoid reduction. There were fever, limb nodules, erythema with ulcerative necrosis, intermittent abdominal pain when she came to our hospital. Blood examination showed that her white blood cells, red blood cells and platelets were decreased, fibrinogen was decreased, triglyceride was increased, ferritin and soluble interleukin-2 receptor(SIL-2R/sCD25) were significantly raised, and hemophagocytic cells were found in bone marrow aspiration. It was found that Epstein-Barr virus DNA was transiently positive, skin Staphylococcus aureus infection, and pulmonary Aspergillus flavus infection, but C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were normal, and no evidence of tumor and other infection was found. Skin pathology was considered panniculitis. The diagnosis was panniculitis, HPS and complicated infection. Antibiotic therapy and symptomatic blood transfusion were given first, but the disease was not controlled. Later, dexamethasone was given, and the condition improved, but the disease recurred after reducing the dose of dexamethasone. Due to the combination of multiple infections, the application of etoposide had a high risk of infection spread. Ruxolitinib, dexamethasone, and anti-infective therapy were given, and her condition remained stable after dexamethasone withdrawal. After 2 months of medication, she stopped using ruxolitinib. One week after stopping using ruxolitinib, she developed fever and died after 2 weeks of antibiotic therapy treatment in a local hospital. In conclusion, panniculitis and HPS are related in etiology, pathogenic mechanism and clinical manifestations. Abnormal activation of Janus-kinase and signal transduction activator of transcription pathway and abnormal release of inflammatory factors play an important role in the pathogenesis of the two diseases. The report suggests that ruxolitinib is effective and has broad prospects in the treatment of panniculitis associated HPS.
