Clinical Spectrum of Capillary Malformation–Arteriovenous Malformation Syndrome Presenting to a Pediatric Dermatology Practice: A Retrospective Study

Capillary malformation–arteriovenous malformation syndrome (CM‐AVM) is an autosomal dominant disorder caused by RASA1 mutations. The prevalence and phenotypic spectrum are unknown. Evaluation of patients with multiple CMs is challenging because associated AVMs can be life threatening. The objective of this study was to describe the clinical characteristics of children presenting with features of CM‐AVM to an academic pediatric dermatology practice. After institutional review board approval was received, a retrospective chart review was performed of patients presenting between 2009 and 2012 with features of CM‐AVM. We report nine cases. Presenting symptoms ranged from extensive vascular stains and cardiac failure to CMs noted incidentally during routine skin examination. All demonstrated multiple CMs, two had Parkes Weber syndrome, and two had multiple infantile hemangiomas. Seven patients had family histories of multiple CMs; three had family histories of large, atypical CMs. Six had personal or family histories of AVMs. Genetic evaluation was recommended for all and was pursued by six families; four RASA1 mutations were identified, including one de novo. Consultations with neurology, cardiology, and orthopedics were recommended. Most patients (89%) have not required treatment to date. CM‐AVM is an underrecognized condition with a wide clinical spectrum that often presents in childhood. Further evaluation may be indicated in patients with multiple CMs. This study is limited by its small and retrospective nature.     

Myocardial perfusion imaging and cardiac events in a cohort of asymptomatic patients with diabetes living in southern France.

AIMS: To assess the association between abnormal stress myocardial perfusion imaging (MPI) and cardiac events (CE) in asymptomatic patients with diabetes and with > or = 1 additional risk factor. Predictors of abnormal stress MPI were also evaluated. METHODS: Four hundred and forty-seven consecutive patients who underwent stress MPI were prospectively followed for 2.1 [0.5-4.1] years for the subsequent occurrence of hard CE (myocardial infarction and sudden or coronary death) and soft CE (unstable angina and ischaemic heart failure requiring hospitalization). Re-vascularization procedures performed as a result of the screening protocol were not included in the analysis. RESULTS: Follow-up was successful in 419 of 447 patients (94%), of whom 71 had abnormal MPI at baseline. Medical therapy was intensified in all subjects and especially in those with abnormal MPI. Twenty-three patients with abnormal MPI underwent a re-vascularization procedure. CEs occurred in 14 patients, including six of 71 patients (8.5%) with abnormal MPI and eight of 348 patients (2.3%) with normal MPI (P < 0.005). Only two patients developed a hard CE and 12 a soft CE. In multivariate analysis, abnormal MPI was the strongest predictor for CEs [odds ratio (OR) (95% CI) = 5.6 (1.7-18.5)]. Low-density lipoprotein cholesterol > or = 3.35 mmol/l [OR (95% CI) = 7.3; 1.5-34.7] and age > median [OR (95% CI) = 6.0 (1.2-28.6)] were additional independent predictors for CE. The independent predictors for abnormal MPI were male gender, plasma triglycerides > or = 1.70 mmol/l, creatinine clearance < 60 ml/min and HbA1c > 8%, with male gender the strongest [OR (95% CI) = 4.0 (1.8-8.8)]. CONCLUSIONS: Asymptomatic patients with diabetes in this study had a very low hard cardiac event rate over an intermediate period. This could be explained by the effects of intervention or by the low event rate in the background population. Randomized studies of cardiac heart disease screening are required in asymptomatic subjects with diabetes to determine the effectiveness of this intervention.     

Dexamethasone adjunctive treatment for tuberculous meningitis

During a 5-year period, 280 of 2010 patients admitted to the meningitis ward of a referral hospital in Cairo, Egypt, were clinically diagnosed as having tuberculous meningitis and were treated with either antituberculous chemotherapy and dexamethasone or antituberculous chemotherapy alone. Fatality rates and neurologic sequelae were compared for the 2 treatment groups in the 160 patients who had cerebrospinal fluid cultures positive for Mycobacterium tuberculosis. The overall mortality rate of 51% reflects the delay in receiving appropriate therapy (79% with symptoms for more than 2 weeks) and the severity of illness on admission (56% in coma, 39% drowsy). The fatality rate was significantly lower in the group receiving dexamethasone (43% vs. 59%, P less than 0.05), particularly in the drowsy patients (15% vs. 40% P less than 0.04), and in patients surviving long enough to receive at least 10 days of treatment (14% vs. 33%, P less than 0.02). Development of neurologic complications after initiation of therapy (4 vs. 10) and permanent sequelae (6 vs. 13) were significantly lower in the dexamethasone-treated group (P less than 0.02).     

Relationship between Intracranial Granulomas and Cerebrospinal Fluid Levels of Gamma Interferon and Interleukin-10 in Patients with Tuberculous Meningitis

Cerebrospinal fluid gamma interferon (IFN-γ) and interleukin-10 levels in 39 patients with tuberculous meningitis were serially measured. Cytokine levels did not predict intracranial granuloma (IG) development, but IFN-γ levels in the top quartile after 1 month of therapy were highly associated (odds ratio = 18) with detection of an IG by computed tomography scanning.     

Scorpion sting: a management problem.

Admissions for scorpion sting in 1 year and deaths resulting from scorpion sting over 3 years were analysed. Features that indicated the severity of the clinical condition were identified. Pulmonary oedema and shock were the usual causes of death. Poor management of fluid therapy was responsible for the frequently unsatisfactory resolution of envenoming, especially when purified human plasma was used. The role of the scorpion antivenom used is questioned and controversy regarding the most appropriate sedative to use in the management of scorpion sting is still not resolved. An in-depth study of these management issues is urgently required.     

创伤病人的手术与焦虑状态调查

采用状态——特质焦虑问卷及１０项躯体性焦虑测试题，对４０例外科创伤病人手术前后的焦虑状态调查显示：术前状态焦虑量表评分显著高于术后；术前躯体性焦虑评分显著高于术后；高特质焦虑评分亚组与低特质焦虑评分亚组术前状态焦虑评分无显著差异，但术后则前者显著高于后者；急诊手术者手术前后状态焦虑评分显著高于择期手术者。
