Individual Case Reports (individual + case_report)
Selected AbstractsSesquiterpene lactone dermatitis in the young: is atopy a risk factor?CONTACT DERMATITIS, Issue 1 2008Evy Paulsen Screening for Compositae contact allergy has documented fairly high prevalence in adults, and recent studies indicate that the allergy may be more common in children than previously believed. However, detailed information on sensitization in this age group is sparse. The objective of this study was to present another 2 cases in children and review the literature. Screening with sesquiterpene lactone (SL) mix has shown prevalence of 0.5% and 1.8% in 2 studies, while screening with 2 different Compositae mixes detected 4.2% and 2.6% positives among children and adolescents. All individual case reports describe sensitization in atopic children, and the largest screening study showed a prevalence of Compositae mix sensitization that was significantly higher in children with atopic dermatitis compared with non-atopics. Compositae sensitization should be considered in children with a family or personal history of atopy, summer-related, or -exacerbated dermatitis of any kind, and a history of plant exposure. Screening with SL mix is recommended but should be supplemented with plant extracts based on exposure history. Compositae weeds, especially dandelions, seem to be important sensitizers in children. [source] Bernard Soulier syndrome in pregnancy: a systematic reviewHAEMOPHILIA, Issue 4 2010P. PEITSIDIS Summary., Bernard Soulier syndrome (BSS) is a rare disorder of platelets, inherited mainly as an autosomal recessive trait. It is characterised by qualitative and quantitative defects of the platelet membrane glycoprotein (GP) Ib-IX-V complex. The main clinical characteristics are thrombocytopenia, prolonged bleeding time and the presence of giant platelets. Data on the clinical course and outcome of pregnancy in women with Bernard Soulier syndrome is scattered in individual case reports. In this paper, we performed a systematic review of literature and identified 16 relevant articles; all case reports that included 30 pregnancies among 18 women. Primary postpartum haemorrhage was reported in 10 (33%) and secondary in 12 (40%) of pregnancies, requiring blood transfusion in 15 pregnancies. Two women had an emergency obstetric hysterectomy. Alloimmune thrombocytopenia was reported in 6 neonates, with one intrauterine death and one neonatal death. Bernard Soulier syndrome in pregnancy is associated with a high risk of serious bleeding for the mother and the neonate. A multidisciplinary team approach and individualised management plan for such women are required to minimise these risks. An international registry is recommended to obtain further knowledge in managing women with this rare disorder. [source] Neuroleptic malignant syndrome and its controversies,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 5 2010Branimir Margeti Abstract Purpose Neuroleptic malignant syndrome (NMS) is a rare and life threatening condition usually defined as a complication of treatment with antipsychotics characterized by severe rigidity, tremor, fever, altered mental status, autonomic dysfunction, and elevated serum creatine phosphokinase and white blood cell count. The literature on this topic is rather extensive, but many aspects related to the syndrome are thought to be controversial. The aim of this paper, written with the clinician in mind, is to summarize some of the most prominent controversies that may have importance in usual clinical practice. Methods The literature was searched for reviews, reports on the series of cases, individual case reports of NMS, and other clinically and theoretically important information. Results There are controversies associated with virtually all important aspects of NMS. At the moment, it is not clear if this drug reaction is idiosyncratic or not, what diagnostic criteria are the most appropriate for usual clinical practice, and it seems that the estimated incidence is not in accordance with the number of treated patients. There are rather different approaches to the pathophysiological mechanisms, differential diagnosis, and treatment. Conclusions Some of the controversies related to NMS have an influence on our understanding of the condition and may have importance in clinical practice. There is a need for further research that should elucidate these controversies. Copyright © 2010 John Wiley & Sons, Ltd. [source] Acromioclavicular joint cyst formationCLINICAL ANATOMY, Issue 2 2010Andrew D. Hiller Abstract Acromioclavicular joint (ACJ) cysts are an uncommon and unusual sequela associated with shoulder pathophysiology. The majority of literature on ACJ cysts consists of individual case reports with no definitive literature review currently available. In addition to a comprehensive literature review, four clinical cases are presented in this report. First described by Craig (1984), a total of 41 cases have been previously reported in the literature. Of these cases, five occurred with the rotator cuff musculature intact. The remaining 36 cases of ACJ cysts occurred in patients with a complete tear/avulsion of the rotator cuff. Previous attempts at compiling a complete record of all reported cases have combined several distinct conditions into a single category. This article presents two distinct etiologies for the pathogenesis of ACJ cyst formation. In the presence of an intact rotator cuff, a Type 1 cyst can form superficially and be limited to the ACJ. Following a massive or traumatic tear of the rotator cuff, mechanical instability of the humeral head can cause a deterioration of the inferior acromioclavicular capsule (cuff tear arthropathy) and an overproduction of synovial fluid. Overtime, a "geyser" of fluid can form between the glenohumeral and the ACJ, forming a Type 2 cyst. This differentiation and categorization is essential for appropriate classification and treatment.
