Multisystem Involvement (multisystem + involvement)
Selected AbstractsLangerhans cell histiocytosis in lymph nodes , cytomorphological diagnosis and pitfallsCYTOPATHOLOGY, Issue 6 2000S. Kakkar Background Langerhans cell histiocytosis (LCH) is a rare disorder of unknown aetiology that may present as a multisystem or unisystem disease. The Lymph nodes can be involved as part of disseminated disease, as a metastatic site draining a focus of LCH or may be a unisystem involvement. Paucity of literature on the cytomorphology of LCH in lymph nodes led us to undertake this study. Materials and methods Nine cases with a confirmed histological diagnosis of LCH and a prior lymph node aspirate were retrieved over a 12 year period (1988,1999). Five more cases were reviewed where the cytological diagnosis of LCH was rendered on a background of clinical and radiological findings. Papanicolaou and May Grunwald,Giemsa-stained smears were examined. S-100 protein staining was available in four cases. Results and conclusions Nine cases had multisystem involvement, while in five cases only lymph nodes were involved. There were eleven males and three females; age ranged from five months to 27 years. The cytological diagnosis of LCH had been rendered in six, suspected in four and missed in four. Of the latter, two were reclassified as LCH on review, one as reactive lymphadenitis and in one a necrotising lesion was suspected. The pathognomonic ,LCH cell' was identified in 12 of 14 cases along with varying numbers of eosinophils, polymorphs and lymphocytes. Giant cells were seen in only six cases. In conclusion lymph node involvement by LCH can be identified on aspirates. However, LCH must be differentiated from dermatopathic lymphadenitis, sinus histiocytosis with massive lymphadenopathy and Hodgkin's disease.

New evidence suggests that a chronic course and multisystem involvement is the rule, rather than the exception, and that together with disturbances of circadian rhythms, mood instability, cognitive impairment, a high rate of medical burden is often observed. The current diagnostic approach for BD neither describes the multisystem involvement that the recent literature has highlighted nor points toward potential predictors of long- term outcome. In light of the new evidence that the long-term course of BD is associated with a high prevalence of psychiatric comorbidity and an increased mortality from medical disease, we propose a multidimensional approach that includes several symptom domains, namely affective instability, circadian rhythm dysregulation, and cognitive and executive dysfunction, presenting in various combinations that give shape to each individual presentation, and offers potential indicators of overall long-term prognosis.

[source] Drug rash with eosinophilia and systemic symptoms secondary to sulfasalazineJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 4 2010Jeremy Rosenbaum Abstract A severe cutaneous eruption in an unwell patient can be a major cause of physician anxiety. With numerous differential diagnoses, an early accurate diagnosis can be challenging. infectious causes are the most important to exclude in a timely manner and drug rash and eosinophilia with systemic symptoms (DRESS) is another differential diagnosis that should be considered in children. This hypersensitivity reaction is associated with multisystem involvement. Children with underlying chronic diseases may have impairment of normal metabolic pathways and are also often on multiple medications. Therefore, drugs should always be considered in the aetiopathology of any new symptoms and signs. This case report informs readers of the association of sulfasalazine and DRESS in an 11-year-old with inflammatory bowel disease and discusses its pathogenesis and treatment. Increased awareness of this disorder will hopefully lead to increased reporting and consequently illuminate the syndrome more clearly and help guide its prevention and treatment. [source] De novo mutation in the mitochondrial tRNALeu(UUR) gene (A3243G) with rapid segregation resulting in MELAS in the offspringJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 1 2001CH Ko Abstract: A 14-year-old Chinese boy with a normal perinatal and early developmental history presented at 5 years of age with migraine, intractable epilepsy, ataxia, supraventricular tachycardia, paralytic ileus and progressive mental deterioration. Computerized tomography revealed multiple cerebral infarcts in the parieto-occipital region without basal ganglial calcification. Magnetic resonance imaging showed increased signal intensity in T2 weighted images in the same regions. A cerebral digital subtraction angiogram was normal. Venous lactate, pyruvate, lactate to pyruvate ratio and cerebrospinal fluid lactate were elevated. Muscle biopsy did not reveal any ragged red fibres; dinucleotide,tetrazolium reductase activity was normal. Mitochondrial DNA analysis detected an adenine to guanine mutation at nucleotide position 3243 of tRNALeu(UUR). All four tissues analysed demonstrated heteroplasmy: leucocyte 56%, hair follicle 70%; buccal cell 64%; muscle 54%. The mother and brother of the proband, both asymptomatic, were also found to have a heteroplasmic A3243G mutation in the leucocytes, hair follicle and buccal cells. Other members of the maternal lineage, including the maternal grandmother, did not have the mutation. This report describes a patient with mitochondrial encephalopathy, lactic acidosis, stroke-like episodes, who presented with multisystem involvement. The absence of ragged red fibres in muscle biopsy did not preclude the diagnosis. Mutational analysis of mitochodrial DNA conveniently confirmed the diagnosis of the disorder. A de novo mutaton is demonstrated in this family. [source] Myotonic dystrophy type 1 (DM1) presenting with laryngeal stridor and vocal fold paresisMUSCLE AND NERVE, Issue 4 2002Jennifer L. Ahmadian MD Abstract Myotonic dystrophy type 1 (DM1) is the most common inherited muscle disorder and may present in numerous ways due to characteristic multisystem involvement. We report a 47-year-old man who presented with an 8-year history of slowly progressive dyspnea and episodic stridor. The laryngeal paresis was documented with videostroboscopy and laryngeal electromyography, and treated with tracheostomy and antimyotonia agents. © 2002 Wiley Periodicals, Inc. Muscle Nerve 25: 000,000, 2002 [source] Aicardi,Goutières syndrome presenting with haematemesis in infancyACTA PAEDIATRICA, Issue 12 2009D Hall Abstract Aicardi,Goutières syndrome is a genetic childhood encephalopathy characterized by basal ganglia calcification, chronic cerebrospinal lymphocytosis and elevated cerebrospinal fluid interferon-alpha, mimicking acquired congenital viral infections. As more is discovered about the pathogenesis of Aicardi,Goutières, it is becoming evident that a dysfunction of the immune system is likely to be responsible for the disease phenotype. We describe a previously healthy 2-month-old female infant who presented with haematemesis and seizures and was subsequently diagnosed with Aicardi,Goutières syndrome. To our knowledge, this is the first documented case of Aicardi,Goutières syndrome presenting with haematemesis. The gastrointestinal tract is an area of high cell loss, revealing early signs of systemic inflammation and we postulate that a systemic proinflammatory milieu occurs in Aicardi,Goutières syndrome. Conclusion: Aicardi,Goutières syndrome can present with haematemesis, adding to the growing evidence that the Aicardi,Goutières syndrome spectrum encompasses an immune-mediated multisystem involvement. Gastrointestinal inflammation should also be considered in these patients and treated appropriately. [source] | ||||||||||
