Selected AbstractsClinical presentations of alopecia areataDERMATOLOGIC THERAPY, Issue 4 2001Maria K. Hordinsky Alopecia areata (AA) may can occur on any hair-bearing region. Patients can develop patchy nonscarring hair loss or extensive loss of all body hair. Hair loss may fluctuate. Some patients experience recurrent hair loss followed by hair regrowth, whereas others may only develop a single patch of hair loss, never to see the disease again. Still others experience extensive loss of body hair. The heterogeneity of clinical presentations has led investigators conducting clinical therapeutic trials to typically group patients into three major groups, those with extensive scalp hair loss [alopecia totalis (AT)], extensive body hair loss [alopecia universalis (AU)], or patchy disease (AA). Treatment outcomes have been correlated with disease duration and extent. Recently, guidelines were established for selecting and assessing subjects for both clinical and laboratory studies of AA, thereby facilitating collaboration, comparison of data, and the sharing of patient-derived tissue. For reporting purposes the terms AT and AU, though still used are defined very narrowly. AT is 100% terminal scalp hair loss without any body hair loss and AU is 100% terminal scalp hair and body loss. AT/AU is the term now recommended to define the presence of AT with variable amounts of body hair loss. In this report the term AA will be used broadly to encompass the many presentations of this disease. Development of AA may occur with changes in other ectodermal-derived structures such as fingernails and toenails. Some investigators have also suggested that other ectodermal-derived appendages as sebaceous glands and sweat glands may be affected in patients experiencing AA. Whether or not function of these glands is truly impaired remains to be confirmed. Many patients who develop patchy or extensive AA complain of changes in cutaneous sensation, that is, burning, itching, tingling, with the development of their disease. Similar symptoms may occur with hair regrowth. The potential involvement of the nervous system in AA has led to morphologic investigations of the peripheral nervous system as well as analysis of circulating neuropeptide levels. In this article the clinical presentations of AA are reviewed. The guidelines for conducting treatment studies of AA are presented and observations on changes in cutaneous innervation are introduced. Throughout the text, unless otherwise noted, AA will be used in a general way to denote the spectrum of this disease. [source] A neuropsychological assessment of frontal cognitive functions in Prader,Willi syndromeJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 5 2007J. Jauregi Abstract Background Prader,Willi syndrome (PWS) is associated with a characteristic behavioural phenotype whose main features are, alongside compulsive hyperphagia, deficits in social behaviour: social withdrawal, temper tantrums, perseverative speech and behaviour, mental rigidity, stereotyped behaviour, impulsiveness, etc. Similar symptoms may also be found in autistic spectrum disorders and lesional pathologies of the frontal lobe. In both cases, such symptoms have been related to dysfunctions in frontal cognitive processes such as attention, working memory and executive functions. This study uses standardized neuropsychological instruments to analyse the degree to which these processes are affected in PWS. Methods The sample comprised 16 individuals with a genetically confirmed PWS diagnosis. Subjects' IQ (Wechsler Adult Intelligence Scale), academic level, laterality and body mass index (BMI) were calculated. Attention, memory and executive functions were analysed using standard, widely employed neuropsychological tests. We compared the results of the sample group with the general population. Correlation analyses were carried out with IQ, academic level and BMI. Results In all the neuropsychological measures focusing on attention, executive functions and visuoperceptual organization, the study sample scored significantly lower than the normative reference population. The scores of the tests used for measuring immediate memory were also significantly lower when trials required sequential processing, although not when they required simultaneous processing. In the memorization of a list of words, subjects showed an initial deficit which disappeared with repetition, enabling them to obtain scores similar to the reference population. No significant correlations were found with BMI, and a higher IQ or academic level did not improve scores in the majority of tests. Conclusions The study shows a deficit in elementary frontal cognitive processes in PWS patients. This deficit may be involved in the social behaviour disorders that characterize such patients, as described in other development or frontal syndrome pathologies. However, we cannot affirm that the deficits found are specific to PWS; they could also occur in other causes of intellectual disability. Although in the study sample IQ did not correlate with frontal deficits, further research is needed to establish whether the neuropsychological alterations described form part of a cognitive phenotype for PWS. We believe that our understanding of the social behaviours typical of PWS may be improved by taking into consideration the cognitive functioning models of the prefrontal lobe, particularly those applied to pervasive developmental disorders. [source] Differential diagnosis of myotonic disordersMUSCLE AND NERVE, Issue 3 2008Timothy M. Miller MD Abstract The presence of myotonia and paramyotonia on clinical examination and of myotonic discharges during electrodiagnostic (EDX) studies are important for the diagnosis of certain neuromuscular conditions. The increased muscle activity of myotonia produces muscle stiffness that improves with repeated activity. Paramyotonia produces a similar symptom, but the stiffness paradoxically increases with activity. Myotonic discharges are easily recognized on EDX testing because of the waxing and waning discharges. Myotonic dystrophy and myotonia congenita share both clinical and electrodiagnostic myotonia. Paramyotonia congenita and hyperkalemic periodic paralysis are associated with clinical paramyotonia and electrical myotonia. Acid maltase deficiency often produces myotonic potentials without clinical evidence of myotonia or paramyotonia. The differential diagnosis of these myotonic disorders is discussed. Muscle Nerve, 2007 [source] Hereditary neuropathy with liability to pressure palsies associated with central nervous system myelin lesionsEUROPEAN JOURNAL OF NEUROLOGY, Issue 6 2001J. Dac Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominant disorder most commonly caused by a 1.5-Mb deletion in chromosome 17p11.2 which contains the peripheral myelin protein-22 (PMP22) gene. Mutations resulting in functional loss of one PMP22 gene copy are less frequent. We present a 51-year-old patient with a l.5-Mb deletion in chromosome 17p11.2 who exhibited signs of peripheral as well as central nervous system lesions. He gave a history of recurrent episodes of limb numbness and weakness with spontaneous but incomplete recovery since age 20. His father and two brothers had similar symptoms. Neurological examination revealed signs of multiple mononeuropathy associated with frontal lobe, corticospinal tract and cerebellar dysfunction, as well as signs of initial cognitive impairment. Electrophysiological investigations showed a demyelinating peripheral nerve disease with multiple conduction blocks and conduction disturbances in both optic nerves. Magnetic resonance imaging of the brain revealed multiple subcortical and periventricular foci of myelin lesions. The association of central and peripheral nervous system lesions in this patient indicates a possible role of PMP22 not only in peripheral but also in central nervous system myelin structure. [source] The human orthologue of murine Mpzl3 with predicted adhesive and immune functions is a potential candidate gene for immune-related hereditary hair lossEXPERIMENTAL DERMATOLOGY, Issue 3 2009Peter Racz Abstract:, We have recently reported a mutation within the conserved immunoglobulin V-type domain of the predicted adhesion protein Mpzl3 (MIM 611707) in rough coat (rc) mice with severe skin abnormalities and progressive cyclic hair loss. In this study, we tested the hypothesis that the human orthologue MPZL3 on chromosome 11q23.3 is a candidate for similar symptoms in humans. The predicted conserved MPZL3 protein has two transmembrane motifs flanking an extracellular Ig-like domain. The R100Q rc mutation is within the Ig-domain recognition loop that has roles in T-cell receptors and cell adhesion. Results of the rc mouse study, 3D structure predictions, homology with Myelin Protein Zero and EVA1, comprehensive database analyses of polymorphisms and mutations within the human MPZL3 gene and its cell, tissue expression and immunostaining pattern indicate that homozygous or compound heterozygous mutations of MPZL3 might be involved in immune-mediated human hereditary disorders with hair loss. [source] Managing obstruction of the central airwaysINTERNAL MEDICINE JOURNAL, Issue 6 2010J. P. Williamson Abstract Lung cancer is the most common cause of cancer death in Australia, Europe and the USA. Up to 20,30% of these cancers eventually affect the central airways and result in reduced quality of life, dyspnoea, haemoptysis, post-obstructive pneumonia and ultimately death. Non-malignant processes may also lead to central airway obstruction and can have similar symptoms. With the development of newer technologies, the last 20 years have seen the emergence of the field of interventional pulmonology to deal specifically with the diagnosis and management of thoracic malignancy, including obstruction of the central airways. This review discusses the pathology, pre-procedure work-up and management options for obstructing central airway lesions. Several treatment modalities exist for dealing with endobronchial pathology with local availability and expertise guiding choice of treatment. While the literature lacks large, multicentre, randomized studies defining the optimal management strategy for a given problem, there is growing evidence from numerous case studies of improved physiology, of quality of life and possibly of survival with modern interventional techniques. [source] Persecutory symptoms and perceptual disturbance in a community sample of older people: the Islington studyINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2001G. Livingston Abstract Background While there are extensive studies of paranoid symptoms and perceptual disturbance (PPD) in younger adults, relatively little is known about older adults with similar symptoms. Method This study took place in Islington, an inner London borough. Enumeration Districts were randomised to provide a sampling frame. Residents aged 65 or over were interviewed at home. The Short-CARE was used to elicit psychiatric symptoms and diagnosis. Sociodemographic particulars were elicited using the Client Sociodemographic and Service Receipt Inventory. Questions were asked regarding sight and hearing. We used subsections of the geriatric mental scale to identify people who had PPD symptoms. Medications taken were recorded. We asked ,Do you have any health problems?' as a screening question for subjective health problems. Results We interviewed 720 people. Twenty-eight (3.9%) participants scored positively on the PPD sub-scales of the GMS. A forward logistic regression analysis for independent predictors of PPD found the significant independent predictors were dementia (p,=,0.0000; odds ratio 6.8), drinking alcohol in last 6 months (p,<,0.03; odds ratio 0.3), drinking alcohol to help sleep (p,<,0.005; odds ratio 9.6), subjective memory loss (p,<,0.007; odds ratio 3.3) and uncorrected visual impairment (p,<,0.02; odds ratio 2.8). Conclusion There is a relatively high prevalence of PPD in older people living in the community. This is not associated with higher use of services despite the increased needs. Further studies should consider interventions to meet this unmet need. Copyright © 2001 John Wiley & Sons, Ltd [source] Association of Sjögren's syndrome and rosacea: a diagnostic challengeINTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 2 2007Leopoldo Luiz Dos SANTOS-NETO Abstract Both Sjögren's syndrome and rosacea present clinical manifestations that include ocular involvement. We report a case of a 45-year-old woman with a history of persistent erythematous malar rash, associated with conjunctival hyperemia, xerophthalmia and blefaritis. The patient filled the current classification criteria proposed for Sjögren's syndrome and those for rosacea. The coexistence of these diseases has not been previously described in the literature. Both diseases have similar symptoms and different treatment approaches. We believe that it is important for clinicians to identify this association in order to provide better care for the patient. [source] Recurrent Abdominal Pain in Children: Forerunner to Adult Irritable Bowel Syndrome?JOURNAL FOR SPECIALISTS IN PEDIATRIC NURSING, Issue 3 2003Monica Jarrett PhD ISSUES AND PURPOSE Review the etiology and pathophysiology of recurrent abdominal pain (RAP) and its potential role as a precursor to irritable bowel syndrome (IBS) in adults. CONCLUSIONS Physiological mechanisms not easily identifiable as an organic cause may underlie symptoms in RAP patients. They may be triggered by psychosocial factors that result in greater functional disability, more clinic visits, and lower academic and social competence. Of these children, 25% will experience similar symptoms as adults; many will be diagnosed with IBS. PRACTICE IMPLICATIONS Nurses can provide early and efficient management of these children's care if they view the issues of abdominal pain/discomfort from a broader focus that includes the context of the child's experiences. [source] Diagnostic issues for adolescents and adults with ADHDJOURNAL OF CLINICAL PSYCHOLOGY, Issue 5 2005Jeanette WassersteinArticle first published online: 18 FEB 200 Attention deficit hyperactivity disorder (ADHD) is a common childhood neuropsychiatric syndrome once thought to disappear with maturation. Current data indicate that ADHD remains "hidden" in many of the grownups who had it as children. Adult prevalence rates range from 1% to 6% of the population. Research suggests the core childhood symptoms of hyperactivity, inattention, and impulsivity shift with development, perhaps transforming into more overt difficulties in executive functions and affect regulation. ADHD is also usually nestled with other comorbid psychiatric conditions, especially in adolescents and adults, further complicating diagnosis and treatment. This article discusses how to recognize and diagnose ADHD in older patients. Key points include core symptoms present during childhood, appropriate family history in this strongly genetic condition, management of comorbidity, and the evolving role of diagnostic testing. Other medical causes for similar symptoms are considered. © 2005 Wiley Periodicals, Inc. J Clin Psychol/In Session 61: 535,547, 2005. [source] Hypercalcaemia of malignancy: an undiagnosed and undertreated diseaseJOURNAL OF INTERNAL MEDICINE, Issue 1 2001O. Lamy Lamy O, Jenzer-Closuit A, Burckhardt P (University Hospital, Lausanne, Switzerland). Hypercalcaemia of malignancy: an undiagnosed and undertreated disease. J Intern Med 2001; 250: 73,79. Background.,Hypercalcaemia of malignancy, a relatively frequent phenomenon, seems to be insufficiently recognized and treated. Its symptoms are not specific, but they affect the quality of life. Methods.,A prospective study to analyse the influence of symptoms caused by hypercalcaemia on the decision of the admitting physician, the motivation for treatment, and the effect of the treatment on the given symptoms in hospitalized patients with oncologic disease in progression, where confounding causes of similar symptoms such as cerebral metastasis, radiotherapy, treatment with opioids, etc., were excluded. Results.,A total of 71 patients, mean age 65 + 11 years, fulfilled the strict inclusion criteria. About 42% were hospitalized because of symptoms caused by hypercalcaemia, but none of the medical reports mentioned hypercalcaemia as reason for hospitalization. Specific antihypercalcaemic therapy was given to only 37% of patients, and only 25% got an adequate rehydratation. Antihypercalcaemic treatment was guided by the severity of hypercalcaemia (>3.00 mmol L,1), not by the symptoms. Polyuria-polydipsia, nausea-vomiting and constipation were correlated with hypercalcaemia. These symptoms, as well as confusion-stupor and bone pains improved significantly when calcaemia was normalized. Patients with calcaemia normalized returned home most frequently (P < 0.03). Conclusions.,Malignant hypercalcaemia remains mostly undiagnosed in medical praxis. Specific treatment occurs in too small fractions of the patients. As the normalization of calcaemia significantly improves the symptoms because of hypercalcaemia and the quality of life, rapid rehydration and specific calcium lowering treatments should be part of palliative measures in all patients with malignant hypercalcaemia. [source] When William of Ockham meets Thomas Bayes: finding a few diagnoses among a great many symptomsALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 9 2001A. Sonnenberg Bayes' formula is a means to estimate disease probability based on the presence of symptoms and the outcome of clinical tests. The probability helps to decide among competing diagnostic options. If, however, several diseases present with similar symptoms, they may appear equally probable, and Bayes' formula will fail as an aid to reach a diagnostic decision. The aim of this study is to show how a merger of Bayes' principle with that of Ockham can help to decide in favour of one diagnosis among multiple, seemingly equally probable diagnostic hypotheses. The hypotheses are compared to each other with respect to those tests and symptoms which they fail to explain. The unexplained tests and symptoms are used to estimate the probabilities for a set of secondary diagnoses that match each one of the primary diagnoses. The more likely a secondary diagnosis appears, the less likely its corresponding primary diagnosis will remain as the sole diagnosis to explain all the clinical findings. Even without a detailed calculation, the proposed concept of using unexplained tests and symptoms to rate competing differential diagnoses could help the clinician to select the most probable diagnosis. [source] Neuroleptic malignant syndrome with severe liver failureACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2003S. H. Urving A schizophrenic patient on long-time neuroleptic medication was admitted with ileus. Secondarily, a high fever, rigidity, mental confusion, tachycardia and hypotension developed. After bromocriptine was given, the temperature dropped by 2°C and the patient improved markedly. A diagnosis of neuroleptic malignant syndrome was made. Five years later she was re-admitted with similar symptoms and also severe liver failure. Meanwhile the discontinued neuroleptic medication had been reinstituted. Again bromocriptine reduced the temperature of approximately 2°C, and was paralleled by a normalization of liver function. To our knowledge this is the second report on severe liver failure in conjunction with neuroleptic malignant syndrome. The efficacy of bromocriptine in the treatment of this syndrome is underlined. [source] Scutular tinea of the scrotum: report of two casesMYCOSES, Issue 3 2005Auro Prochnau Summary Infections caused by dermathophytes in the scrotal skin are uncommon especially due to Microsporum gypseum, which may form scutular or favus-like lesions. We report two patients with this type of tinea: one immune suppressed by HIV infection and another immunocompetent without comorbidity. In the literature we found only two reports in immunocompetent patients and some in immune suppressed with similar symptoms. [source] Marinesco-Sjögren syndrome with atrophy of the brain stem tegmentum and dysplastic cytoarchitecture in the cerebral cortexNEUROPATHOLOGY, Issue 5 2008Kenji Sakai Marinesco-Sjögren syndrome (MSS) is a progressive multisystem disease with autosomal recessive inheritance characterized by cataracts, mental retardation, and cerebellar ataxia. Recently, two causative genes for MSS, SIL1 and SARA2, have been identified. On the other hand, the histopathologic features of the CNS in this syndrome have not yet been clarified in detail. We report here the features of an autopsy case of MSS with progressive myopathy, in which atrophy of the cerebellum and brain stem tegmentum, retinal degeneration, and dysplastic cytoarchitecture in the cerebral cortex were evident. An elder brother of the patient showed quite similar symptoms, implying an autosomal recessive mode of inheritance. However, we detected no mutations in the available genes. This case appears to represent an unusual example of MSS manifesting widespread developmental anomaly and neuronal degeneration in the CNS. [source] A Severe Case of Complex Regional Pain Syndrome I (Reflex Sympathetic Dystrophy) Managed with Spinal Cord StimulationPAIN PRACTICE, Issue 1 2010Bernard Canlas MD Abstract Complex regional pain syndrome is a condition that usually affects the upper or lower extremities. The cause is not clearly understood. We report a case of a severe form of a rapidly progressive complex regional pain syndrome type I developing after a right shoulder injury managed with spinal cord stimulation (SCS). After failed conservative treatments, a rechargeable SCS system was implanted in the cervical spine. Allodynia and dystonia improved but the patient subsequently developed similar symptoms in lower right extremity followed by her lower left extremity. The patient became wheelchair bound. A second rechargeable SCS with a paddle electrode was implanted for the lower extremity coverage. The patient's allodynia and skin lesions improved significantly. However, over time, her initial symptoms reappeared which included skin breakdown. Due to the need for frequent recharging, the system was removed. During explantation of the surgical paddle lead, it was noted by the neurosurgeon that the contacts of the paddle lead were detached from the lead. After successful implantation of another SCS system, the patient was able to reduce her medications and is now able to ambulate with the use of a left elbow crutch. [source] Differences in host range, pathogenicity to potato cultivars and response to soil temperature among Streptomyces species causing common and netted scab in FrancePLANT PATHOLOGY, Issue 1 2000Bouchek-Mechiche The pathogenicity and ecology of some isolates representative of the four main Streptomyces species (S. scabies, S. europaeiscabiei, S. stelliscabiei and S. reticuliscabiei) identified as pathogenic to potato tubers were investigated. Three pathogenicity groups could be distinguished. Group 1 included all isolates of S. scabies, S. europaeiscabiei and S. stelliscabiei from common scab lesions of potato and other susceptible root crops. All these produced similar symptoms and were pathogenic to potato, carrot and radish. Group 2 included all isolates from S. reticuliscabiei netted scab lesions; they were pathogenic to both tubers and roots of only a few potato cultivars, and did not infect carrot or radish. Group 3 included three isolates of S. europaeiscabiei from netted scab lesions on cv. Bintje, which produced either common or netted scab symptoms depending on the potato cultivar or plant species. In an experiment on a few isolates from each of the three groups, held at various soil temperature regimes, the three from group 1 were most pathogenic at higher temperatures (20°C or 20/30°C), the two from group 2 were most pathogenic at a lower temperature (17°C). The group 3 isolate caused netted scab symptoms on susceptible cultivars at low temperatures (, 20°C) and deep-pitted lesions at higher temperatures. Since the groups identified differ in ecological requirements, it is important to adapt the control methods to the pathogenic species present in the soil. [source] Annotation: PANDAS: a model for human autoimmune diseaseTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 3 2005Susan E. Swedo Background:, Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus infections (PANDAS) is a recently recognized syndrome in which pre-adolescent children have abrupt onsets of tics and/or obsessive-compulsive symptoms, a recurring and remitting course of illness temporally related to streptococcal infections, and associated neurologic findings including adventitious movements, hyperactivity and emotional lability. Methods:, Inspired by observations of similar symptoms in children with Sydenham's chorea, a search was undertaken for clinical and laboratory evidence in support of the new syndrome. Results:, Consistent and predictable clinical findings have been described in a large case series. Magnetic resonance imaging has supported the postulated pathobiology of the syndrome with evidence of inflammatory changes in basal ganglia. Antibasal ganglia antibodies have been found in some acute cases, mimicking streptococcal antigen epitopes. Conclusions:, While PANDAS remains a controversial diagnostic concept, it has stimulated new research endeavors into the possible links between bacterial pathogens, autoimmune reactions, and neuropsychiatric symptoms. [source] Epidermolysis bullosa nevus arising in a patient with Dowling,Meara type epidermolysis bullosa simplex with a novel K5 mutationTHE JOURNAL OF DERMATOLOGY, Issue 8 2009Hiroko SUGIYAMA-FUKAMATSU Abstract We report herein a 4-year-old girl with Dowling,Meara type epidermolysis bullosa (EB) who presented with peculiar pigmented nevi. Blister formation had repeatedly occurred on the erythematous plaques in a circinate fashion since birth, and marked hyperkeratosis was observed on the palms and soles associated with nail deformity. Her mother and maternal grandmother also had similar symptoms. In addition to the blistering lesions, the patient had three large, asymmetrical, pigmented plaques with color variegation. Light and electron microscopic findings of the blistering lesions showed a subepidermal blister with intracytoplasmic granules in keratinocytes as well as degeneration of basal cells and aggregation of tonofilaments. The pigmented lesions revealed histopathological features of compound nevus without malignant changes. Gene analysis revealed an E478K (Glu to Lys) mutation in exon 5 of the keratin 5 (K5) gene. These findings, together with clinical features, were consistent with those of Dowling,Meara type EB associated with so-called EB nevus. [source] Onychomycosis in clinical practice: factors contributing to recurrenceBRITISH JOURNAL OF DERMATOLOGY, Issue 2003R.K. Scher Summary The treatment of onychomycosis has improved in recent years and many patients can now expect a complete and lasting cure. However, for up to 25% of patients, persistent disease remains a problem, thus presenting a particular challenge to the clinician. For these patients, it is obviously important to ensure that a correct diagnosis of onychomycosis has been made, as misdiagnosis will inevitably jeopardize the perception of therapeutic effectiveness. Although onychomycosis accounts for about 50% of all nail diseases seen by physicians, nonfungal causes of similar symptoms include repeated trauma, psoriasis, lichen planus, local tumours vascular disorders and inflammatory diseases. Predisposing factors that contribute to a poor response to topical and/or oral therapy include the presence of a very thick nail, extensive involvement of the entire nail unit, lateral nail disease and yellow spikes. However, poor penetration of systemic agents to the centre of infection, or the inability of topical agents to diffuse between the surface of the nail plate and the active disease below, probably contributes to this. Other factors contributing to recurrence may be related to the patient's family history, occupation, lifestyle or underlying physiology. In addition, patients with concomitant disease (e.g. peripheral vascular disease, diabetes) or patients who are immunosuppressed (e.g. those with human immunodeficiency virus/acquired immunodeficiency syndrome) are more susceptible to onychomycosis. In the elderly, the prevalence of onychomycosis may be as high as 60%, and increases with age; in this population, physical trauma plays a major role in precipitating recurrence, especially in patients with faulty biomechanics due to underlying arthritis and bone abnormalities. It is also possible that recurrence in some cases is due to early termination of treatment or use of an inappropriate dose, and these possibilities should be eliminated before further investigations are undertaken. ,There is good evidence to suggest that a combination of oral and topical therapies, when given at the same time, yield excellent clinical outcomes, although there remains a need for more effective topical agents with greater nail penetration and more effective oral antifungal agents. [source] Patients' recall of clinical information following laparoscopy for acute abdominal painBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2004S. M. Murphy Background: Failures in doctor,patient communication and patients' understanding continue to confound improvements in the delivery of quality healthcare. In the context of acute abdominal pain managed by means of laparoscopy, it was hypothesized that patients are either not adequately informed, or do not reliably retain simple relevant information transmitted at the time of the procedure. This study was designed to evaluate the reliability of information transfer between doctor and patient in this setting, including the diagnosis and whether or not the appendix was removed. Methods: A retrospective study of 350 consecutive patients who had undergone laparoscopy for acute abdominal pain over 3·5 years was designed. Each patient completed a telephone questionnaire that was used to evaluate the accuracy of patients' information. Results: In total, 26·9 per cent of patients did not know or were incorrect regarding the surgical procedure performed. Similarly, 20·0 per cent of all patients did not know or were incorrect regarding the status of their appendix after surgery and 30·0 per cent of patients were incorrect regarding the diagnosis. Despite all of these statistics, 91·4 per cent of patients were happy with the information they had received regarding the procedure. Conclusion: Some 26·9 per cent of patients who underwent laparoscopy for acute abdominal pain were incorrect or did not know about the procedure that had been performed. This could lead to a further unnecessary operation should they re-present with similar symptoms. Copyright © 2004 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source] Serological testing for Bartonella henselae infections in The Netherlands: clinical evaluation of immunofluorescence assay and ELISACLINICAL MICROBIOLOGY AND INFECTION, Issue 6 2007M. J. Vermeulen Abstract Cat-scratch disease (CSD), caused by Bartonella henselae infection, can mimic malignancy and can manifest atypically. Reliable serological testing is therefore of great clinical importance. The diagnostic performance of immunofluorescence assay (IFA) and ELISA was evaluated in a group of Dutch patients with proven CSD (clinical diagnosis confirmed by PCR). Sera of 51 CSD patients and 56 controls (patients with similar symptoms, but who were B. henselae PCR-negative and had an alternative confirmed diagnosis) were tested for anti- B. henselae IgM and IgG by IFA and ELISA. A commercially available IFA test for IgM had a sensitivity of 6%. In-house assays for IgM showed specificities of 93% (IFA) and 91% (ELISA), but with low sensitivities (53% and 65%, respectively). With a specificity of 82% (IFA) and 91% (ELISA), in-house IgG testing showed a significantly higher sensitivity in IFA (67%) than in ELISA (28%, p <0.01). Sensitivity was higher for genotype I (38,75%) than for genotype II (7,67%) infections, but this was only statistically significant for IgG ELISA (p <0.05). In conclusion, detection of IgM against B. henselae by in-house ELISA and IFA was highly specific for the diagnosis of CSD. The high seroprevalence in healthy individuals limits the clinical value of IgG detection for diagnosing CSD. Given the low sensitivity of the serological assays, negative serology does not rule out CSD and warrants further investigation, including PCR. Adding locally isolated (e.g., genotype II) B. henselae strains to future tests might improve the sensitivity. [source] | ||||||||||||||||||||||||||||
