Red ear syndrome and auricular erythromelalgia: the same condition?

Several cases of relapsing attacks during which the ear becomes red and patients experience a burning sensation have been reported in the literature. This combination of symptoms has been described as ‘red ear syndrome’ (RES). We report on a 7‐year‐old boy who had episodes of reddening, swelling and a burning sensation in one ear with local hyperthermia persisting for 3 years. The differential diagnosis included RES and erythromelalgia, as isolated auricular variants of erythromelalgia have been described and the symptoms are difficult to distinguish from RES. In this report, we discuss the similarities and differences between RES and erythromelalgia.     

维生素D受体基因多态性与汉族人群慢性牙周炎易感性的关系

目的 探讨维生素D受体(VDR)基因多态性与汉族人群慢性牙周炎(CP)易感性的关系。方法 收集汉族轻、中、重度CP患者共166例及80名无牙周炎对照者的颊黏膜拭子，以Chelex-100法提取DNA，采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法测定VDR BsmI、VDR ApaI和VDR TaqI的基因型，分析组间基因型分布和等位基因频率的差异。结果 轻、中、重度CP患者中VDR ApaI等位基因A携带者明显多于对照组，重度CP与中度CP、重度CP与轻度CP患者间VDR ApaI基因型的分布差异均有统计学意义，中度CP与轻度CP患者间VDR ApaI基因型分布差异无统计学意义，而VDR BsmI、TaqI位点的基因型分布在患者组和对照组间差异无统计学意义。结论 VDR ApaI等位基因A可能与汉族人群CP的易感性有关。     

重视咽异感症的诊治

咽异感症，全称咽部感觉异常，足耳鼻咽喉科常见的病症。本症主指患者咽部有异物、阻塞或刺激等感觉症状的一种病症。由于主诉症状明显，往往又查无器质性病变，有时易被忽略。本症严重者，其痛苦表现及造成的后果不亚于某些器质性病变，且其症状义是多种相关疾病的表症。故应引起广大耳鼻咽喉科医师的重视。     

Classification tree analysis of second neoplasms in survivors of childhood cancer

Background  

Reports on childhood cancer survivors estimated cumulative probability of developing secondary neoplasms vary from 3,3% to 25% at 25 years from diagnosis, and the risk of developing another cancer to several times greater than in the general population.     

Cutaneous leishmaniasis: Clinical report of two cases and review of the recent literature

With 1–1.5 million cases reported every year cutaneous leishmaniasis represents an increasing health problem. The course of cutaneous leishmaniasis varies from a single self‐healing ulcer to a persistent ulcer or progressive mucosal disease with nasopharyngeal destruction. An enormous array of topical and systemic treatment modalities has been endorsed. The response to treatment depends on the species of parasite as well as the host's immunological and genetic status. Species‐specific treatment guidelines based on evidence from controlled studies are highly desirable. We present two cases of cutaneous leishmaniasis, one in a child and one during pregnancy, reviewing various diagnostic and therapeutic measures with special attention to problems in young and pregnant patients.     

Helicobacter pylori infection in epileptic patients.

It is well known that there might be an epidemiological association between Helicobacter pylori infection and extraintestinal diseases. This study aimed at determining H. pylori infection in epileptic patients. Forty-seven cryptogenic epileptic patients (Group 1) and 35 healthy people (Group 2) participated in this study. Presence of H. pylori infection was examined by H. pylori stool antigen (HpSA), H. pylori IgG, and IgM. HpSA was detected in 21 participants (44.6%) in Group 1 and in 3 participants (8.5%) in Group 2. H. pylori IgM was positive in 27 participants (57.4%) in Group 1 and in 8 participants (22.8%) in Group 2. H. pylori IgG was positive in 37 participants (78.7%) in Group 1 and in 13 participants (38%) in Group 2. The difference of rates of HpSA, H. pylori IgM and IgG in Groups 1 and 2 were found statistically significant (chi2=4.18, p=0.04; chi2=9.18, p=0.0017; chi2=14.58, p<0.001, respectively). We also compared presence of H. pylori infection between the epileptic patients with poor and good prognosis; HpSA positivity was detected in 15 (62.5%) of 24 and 6 (26%) of 23, respectively, and the differences were statistically significant (chi2=6.30, p=0.012). H. pylori IgM positivity was detected in 16 (66%) of 24 patients with poor prognosis and 11 (47.8%) of 23 patients with good prognosis (p>0.05). H. pylori IgG positivity was detected in 18 (75%) of 24 patients with poor prognosis and 19 (82.6%) of 23 patients with good prognosis. The differences of H. pylori IgM and IgG positivity rates in epileptic patients with poor and good prognosis were not found statistically significant (p>0.05). These results suggest a probable association between the acute H. pylori infection and epilepsy, especially with poor prognosis.     

血液紫外线照射充氧治疗家兔梭曼急性中毒

目的 探讨紫外线照射充氧(UBIO)对梭曼急性中毒家兔全血乙酰胆酯酶(AchE)活性的影响及对梭曼中毒后肺损伤的治疗作用.方法 家兔40只,随机分为正常对照组、中毒组、常规治疗组及UBIO治疗组各10只,于治疗后2h检测全血AchE 活性及进行动脉血气分析.收集支气管肺泡灌洗液(BALF),分析其中碱性磷酸酶(AKP)、酸性磷酸酶(ACP)活性.结果 中毒组AchE活性显著低于对照组(P<0.01),BALF中AKP及ACP活性高于对照组(P<0.01).经UBIO治疗后AchE活性升高,且明显高于中毒组及常规治疗组.与中毒组比较,UBIO治疗组中AKP及ACP活性显著降低(P<0.05),而动脉血pH值、PaO2及SaO2明显升高(P<0.05),PaCO2明显降低(P<0.05).结论 UBIO能提高全血AchE活性及减轻梭曼中毒后的肺损伤,因而可能是一新的治疗梭曼急性中毒的途径.
