Many rashes associated with fever are caused by infectious diseases. Rashes are generally nonspecific and play a supportive role in differential diagnosis, but for some diseases, the appearance of the rash is essential in making a diagnosis. Here is presented the case of a 4-year-old boy with high fever, headache, abdominal pain, vomiting, diarrhea, and a generalized maculo-papular rash including palms and soles. On physical examination were found a black eschar, cervical lymphadenopathy, and hepatosplenomegaly. Laboratory findings resulted in moderate leukocytosis and moderate involvement of the liver and renal function. Based on this finding, a diagnosis of Mediterranean Spotted Fever was performed. The child recovered after medication with azithromycin. Because there is no reliable test that can confirm MSF in its early stages, the diagnosis is commonly made on the basis of clinical findings, so a high index of suspicion should be maintained while evaluating a child with fever and rash.展开更多

The burden of rubella infection in most developing countries is however not well documented because of lim-ited epidemiological data. Methods: Between 2006 and 2009, 781individuals with febrile rash illness seen in clinics in Akwa Ibom State were screened for rubella specific IgM antibodies using the ELISA technique. Statistical analysis was done using Graph prime version 5.3 statis-tical package at 95% confidence interval. The level of significance was established at P = 0.05 using Fisher’s exact two-tailed values. Results: Of 781 individuals screened for rubella specific IgM antibodies, 94 (12%) were found to be posi-tive. Incidence of 8.7% recorded in 2006 gradu-ally rose to 9.3% in 2007, 11.6% in 2008 and 14.3% in 2009. Those in the reproductive age group (> 16 years) were most affected (51.7%). However, this was not statistically significant (P = 0.228). Females (17.4%) were more suscepti-ble than males (6.2%) (P < 0.0001) an rural dwellers (12.8%) more susceptible than urban dwellers (10.5%) (P = 0.416). Conclusion: The study shows that the incidence of rubella in Akwa Ibom State, Nigeria is high. The lowest incidence was however found among individu-als below the reproductive age. Thus, the find-ings of this study can be used by policy makers to model the introduction of routine rubella vaccination into the country’ Expanded Program on Immunization Schedule (EPI).展开更多

Its safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) were investigated in a randomized, double-blind, placebo-controlled, ascending single-dose study in 48 healthy Japanese male subjects. Fasted subjects were orally administered E3024 (5, 10, 20, 40, or 80 mg) or placebo. E3024 was rapidly absorbed, with tmax values ranging between 0.33 and 3 h after dosing. The mean t1/2 ranged from 5.34 to 11.68 h. AUC0-inf and Cmax increased dose-proportionately. PK-PD relationship of E3024 was evaluated by using an Imax model, indicating that plasma E3024 concentrations and inhibitory effects of plasma DPP-IV activity were well correlated. The IC50 value was calculated as 33.7 ng/mL, which was consistent with in vitro data. Thus, E3024 showed a good PK profile and inhibited DPP-IV dose-dependently. Of 30 subjects administered E3024, 12 (40%) experienced adverse events (AEs). Dose escalation to 160 mg was abandoned owing to undesired subjective/objective findings in 4 of 6 subjects receiving 40 mg and 5 of 6 subjects receiving 80 mg. The most prominent AE was rash, but there were no serious AEs or deaths. The maximum tolerated dose was considered to be 20 mg. We hypothesized that histamine was a cause of the rash induction, and examined blood histamine levels of normal Fischer rats treated with E3024. Blood histamine levels were increased significantly by E3024 at 500 mg/kg (p < 0.001), but not by vildagliptin or valine-pyrrolidide (DPP-IV inhibitors) at the same dose. No blood histamine increases were observed in genetically mast cell-deficient Ws/Ws rats treated with E3024 at 500 mg/kg. In in vitro assays, E3024 induced histamine release from normal rat peritoneal mast cells in a concentration-dependent manner, but not from basophils. The structure-activity relationship study suggested that a piperazine group N-linked to the 2-position of the 5,6-membered fused heterocyclic rings was a key structural element for triggering histamine release.展开更多

The clinical manifestations of psoriatic arthritis with arthritis as the first symptom are often similar to ankylosing spondylitis and rheumatoid arthritis. Thus differential diagnosis should be made in clinical practice so as to improve the therapeutic effect. Psoriatic arthritis skin lesions are usually papules or plaques, with scales on the surface and punctate hemorrhage on the basement. About 10% of patients with psoriatic arthritis have skin rash after the onset of arthritis. In order to provide a reference for clinicians, our study the analyzed the clinical diagnosis of psoriatic arthritis in combination with a case of psoriatic arthritis with concealed skin rash and related literatures.展开更多

Dexpanthenol is a well-known moisturizer with barrier-improving properties and the oily phase of the water in oil preparation forms a lipophilic film on the skin surface that isolates the skin from irritants (feces and urine). Prolonged contact with irritants triggers a local inflammation cascade responsible for the cutaneous erythema. To further investigate the protective properties of skin barrier preparations, we took advantage of an <i>ex vivo</i> model of healthy human skin discs especially designed to evaluate protective and/or repairing effects of topical preparations recommended for baby’s buttocks through the measurement of interleukin-1 alpha release (a cytokine considered as the <em>Primum movens</em> of the skin inflammatory reaction), following the application of different irritants. <strong>Methods: </strong>Healthy human skin discs have been incubated in the absence (control) or in the presence of two irritants,<em> i.e.</em> a “urine like + urease” preparation and sodium dodecyl sulfate, and in the presence of three ointments, one containing dexpanthenol, but not the other two. At the end of the incubation period, interleukin-1 alpha (IL-1<em>α</em>) was quantified in the explants culture media.<strong> Results: </strong>“Urine like + urease” preparation (ULU) and sodium dodecyl sulfate (SDS) both increased IL-1<em>α</em> production of skin explants by 181.1% (p < 0.001) and 88.3% (p < 0.001), respectively. The dexpanthenol containing formula significantly inhibited the ULU- and the SDS-induced IL-1<em>α</em> release by 67.42% (p < 0.001) and 46.55% (p < 0.001), respectively. Under the same experimental conditions, one of the formulas without dexpanthenol significantly inhibited the ULU-induced IL-1<em>α</em> release by 45.94% (p < 0.01) but not the SDS-induced one, and the other tested formulation displayed no significant effect on the IL-1<em>α</em> production regardless of the irritant applied. Moreover, the effect of the dexpanthenol containing formula on the ULU-induced IL-1<em>α</em> release was significantly higher than the effect of the other formula;a difference of 19.6 % (p < 0.05) was observed.<strong> Conclusion: </strong>Dexpanthenol containing formula (BEPANTHEN<sup>®</sup>) provides good protection of baby’s buttocks against irritants. Its protective effect seems to be superior compared with other products, which did not contain this ingredient. Moreover, the results obtained in the present study suggest that dexpanthenol displays <i>per se</i> a real IL-1<em>α</em> production inhibitory effect. This work, however, consists of preliminary studies and additional investigations involving more formulas and end-points such as the quantification of other pro- or anti-inflammatory cytokines and/or resolvins for example, are needed to better understand the cutaneous protective effect of dexpanthenol.展开更多

文摘When febrile illnesses develop a rash in children, parents are very concerned about a serious disease. Many rashes associated with fever are caused by infectious diseases. Rashes are generally nonspecific and play a supportive role in differential diagnosis, but for some diseases, the appearance of the rash is essential in making a diagnosis. Here is presented the case of a 4-year-old boy with high fever, headache, abdominal pain, vomiting, diarrhea, and a generalized maculo-papular rash including palms and soles. On physical examination were found a black eschar, cervical lymphadenopathy, and hepatosplenomegaly. Laboratory findings resulted in moderate leukocytosis and moderate involvement of the liver and renal function. Based on this finding, a diagnosis of Mediterranean Spotted Fever was performed. The child recovered after medication with azithromycin. Because there is no reliable test that can confirm MSF in its early stages, the diagnosis is commonly made on the basis of clinical findings, so a high index of suspicion should be maintained while evaluating a child with fever and rash.

文摘<strong>Background:</strong> Dexpanthenol containing formula (BEPANTHEN<sup>®</sup>), formulated as a water in oil preparation, is currently widely marketed as a diaper care product aiming to protect baby’s buttocks and repair diaper dermatitis. Dexpanthenol is a well-known moisturizer with barrier-improving properties and the oily phase of the water in oil preparation forms a lipophilic film on the skin surface that isolates the skin from irritants (feces and urine). Prolonged contact with irritants triggers a local inflammation cascade responsible for the cutaneous erythema.

At the end of the incubation period, interleukin-1 alpha (IL-1<em>α</em>) was quantified in the explants culture media.<strong> Results: </strong>“Urine like + urease” preparation (ULU) and sodium dodecyl sulfate (SDS) both increased IL-1<em>α</em> production of skin explants by 181.1% (p < 0.001) and 88.3% (p < 0.001), respectively. The dexpanthenol containing formula significantly inhibited the ULU- and the SDS-induced IL-1<em>α</em> release by 67.42% (p < 0.001) and 46.55% (p < 0.001), respectively. Under the same experimental conditions, one of the formulas without dexpanthenol significantly inhibited the ULU-induced IL-1<em>α</em> release by 45.94% (p < 0.01) but not the SDS-induced one, and the other tested formulation displayed no significant effect on the IL-1<em>α</em> production regardless of the irritant applied. Moreover, the effect of the dexpanthenol containing formula on the ULU-induced IL-1<em>α</em> release was significantly higher than the effect of the other formula;a difference of 19.6 % (p < 0.05) was observed.<strong> Conclusion: </strong>Dexpanthenol containing formula (BEPANTHEN<sup>®</sup>) provides good protection of baby’s buttocks against irritants. Its protective effect seems to be superior compared with other products, which did not contain this ingredient. Moreover, the results obtained in the present study suggest that dexpanthenol displays <i>per se</i> a real IL-1<em>α</em> production inhibitory effect. This work, however, consists of preliminary studies and additional investigations involving more formulas and end-points such as the quantification of other pro- or anti-inflammatory cytokines and/or resolvins for example, are needed to better understand the cutaneous protective effect of dexpanthenol.
文摘目的分析人HIV阳性与HIV阴性猴痘患者的临床和影像特征,为临床诊疗提供参考。方法回顾性分析2023年6月1日至11月30日首都医科大学附属北京佑安医院收治住院的36例确诊猴痘患者的临床和影像资料,按照是否合并HIV感染分为HIV阳性组和HIV阴性组。观察比较两组人群临床和影像特征。结果36例猴痘患者均为男性且为男男性行为者(men who have sex with men,MSM),平均年龄(31.5±6.4)岁;HIV阳性组28例,HIV阴性组8例。主要表现为皮疹、发热、淋巴结肿大。皮疹的首发部位(24例,66.7%)和最主要的分布部位(30例,83.3%)均为生殖器和肛门,以丘疹和脓疱疹为主。合并其他性传播性疾病14例(38.9%,14/36);合并细菌感染21例(58.3%,21/36),主要为皮肤软组织感染和肛周感染。影像检查结果异常者均为HIV阳性组患者。4例(11.1%,4/36)肺炎CT表现以磨玻璃影、实变、多发结节为主;2例并发肠梗阻,影像表现以胃肠道扩张为主,2例直肠炎表现为直肠壁增厚,肠腔狭窄。两组患者的流行病学资料、临床特征、皮疹分布及性质和实验室检查结果比较差异均无统计学意义(P>0.05)。结论36例猴痘患者以青壮年MSM人群为主,且多为HIV感染者;生殖器和肛周是皮疹首发和最多发部位,溃疡样皮疹仅见于HIV感染者;轻症患者预后良好,重症患者可合并细菌性感染、肠梗阻和直肠炎。并发肺炎者CT主要表现为实变和磨玻璃影,并可见两肺多发、随机分布的实性结节。
文摘Rationale:Transmitted to humans via the Aedes mosquito,Chikungunya virus(CHIKV)is associated with multi-system complications,sometimes collectively referred to as“atypical features.”However,a disorder of the nervous system appears to be the most common severe complication of CHIKV infection.Patient’s Concern:A seventy-five-year-old patient from India presented to the hospital with fever,chills,rigors,and multiple joint pains for which he was worked up.Diagnosis:CHIKV encephalitis.Interventions:The patient was treated initially on supportive therapy with antipyretics,intravenous fluids;however,during his hospital stay,the patient had altered sensorium during which he was managed in the intensive care unit;required mechanical ventilation.Outcomes:The patient sccumbed to his illness.Lessons:Treating clinicians should keep CHIKV disease in the differential diagnosis in cases of febrile exanthems associated with disabling arthritis,especially in a CHIKV-endemic country like India.
