    We describe two males, aged 41 and 55, come to our observation complaining of heat intolerance, abnormal increase in body temperature with minimal exercising, reduced sweating and, generalized fatigability; one of them had distal paresthesias. Neurologic evaluation showed bilateral Adie's tonic pupil and an absence of deep-tendon jerks. A diagnosis of Ross' Syndrome was advanced. Autonomic tests, nerve conduction study, H-reflex, computerized termoregulatory and pain thresholds, laser CO2 cortical evoked potentials, and skin biopsy were performed. One of them performed a histamine test and hand photopletismography resulted positive for sympathetic impairment, and pilocarpine pupil test that showed a parasympathetic denervation hypersensitivity. The following tests gave the same results in both patients: parasympathetic and most sympathetic tests were normal. Sympathetic skin response was absent and Minor test showed an almost complete absence of sweating. Sweating was possible only in two or three small areas. Positive pilocarpine test suggested a postganglionic involvement of sympathetic nervous system. Sensitive and motor nerve conduction velocities were normal, while H-reflex was not detectable. Termoregulatory and pain thresholds were abnormal. Laser CO2 cortical evoked potentials showed the absence of C fibre potentials, whereas A-, fibres response was abnormal in one of them. Hairy skin biopsy showed a definite reduction of sweat glands and of small vessel innervation; glabrous skin biopsy performed in one of them showed a reduced number of Meissner corpuscles. These findings suggest that in Ross' Syndrome the degenerative process can involve, besides the autonomic fibres, myelinated somatosensory fibres also. [source]

    Unlike peripheral motor disorders, sensory disturbances are rarely diagnosed by the probable site of pathology. This approach is useful in the differential diagnosis between chronic sensory axonal neuropathies and ganglionopathies, in which routine clinical and neurophysiological evaluation alone often do not provide definite clues. Methods: Thirty patients with peripheral sensory disturbances were investigated. MRI was performed at cervical level in all cases. Four patients also underwent thoracic and lumbar MRI. Seventeen patients underwent skin biopsy at the proximal thigh and the distal leg. In 4 of them, further skin biopsies were taken at C5 dermatome and at the hand. Density of intra-epidermal nerve fibers (IENF) was quantified. Results: In 22 patients, sensory ganglionopathy was suspected. Disease was idiopathic in 7 cases; paraneoplastic in 3 cases; and associated with Sjögren, AIDS, autoimmune chronic hepatitis, and cisplatin neurotoxicity in 4 cases. One patient had a hereditary sensory autonomic neuropathy. Four patients had vitamin E deficiency and 3 patients a spinocerebellar syndrome. In 8 patients, sensory axonal neuropathy related to diabetes, alcoholism, and AIDS on antiretroviral treatment, and monoclonal gammopathy of undetermined significance was diagnosed. MRI findings: All ganglionopathy patients showed posterior columns hyperintensity on T2-weighted MRI. Conversely, MRI was negative in all axonal sensory neuropathy patients. Skin biopsy findings: In neuropathies, IENF density was significantly lower at the distal leg than at the proximal thigh, while ganglionopathies did not show any change with respect to the rostral:caudal orientation. A similar pattern of epidermal denervation was observed in the arm. Discussion: The degeneration of both central and peripheral sensory pathway in a fashion that is not length-dependent localizes the disease to T-shaped sensory neurons Early ataxia and cutaneous sensory symptoms involving the proximal regions of the body reflect this pattern of denervation and should prompt the diagnosis of ganglionopathy. This can be confirmed by T2-weighted hyperintensity in the posterior columns and a distinct pattern of IENF loss. [source]

    Valproic acid-induced congenital malformations: Clinical and experimental observations

    R. Padmanabhan
    ABSTRACT With a large number of epileptic women being in the childbearing age group, complications of pregnancy in epileptic patients are of concern. Epileptic women are treated with antiepileptic drugs (AED) whether they are pregnant or not. Contrary to prevailing opinion, recent data suggest that epilepsy per se contributes significantly to birth defects possibly because of the same genetic susceptibility that predisposes to epilepsy. Many of these defects closely resemble those attributed to exposure to AED. The syndromes attributed to various AED also considerably overlap with each other. Valproic acid (VPA) induces several minor and major malformations. The relative risk for spina bifida in VPA exposed pregnancies is nearly 20 times higher than that for the general population and about 10 times higher than that attributed to other anticonvulsants. Fetuses of experimental animals treated with VPA during pregnancy exhibit exencephaly unlike the human offspring in whom VPA induces spina bifida. The cranial and spinal malformations observed in humans and laboratory animals indicate that VPA has a preferentially deleterious effect on the neural crest. Several AEDs including VPA tend to lower maternal plasma folate levels. In view of the beneficial effects of periconceptional folate supplementation in prevention of neural tube defects (NTD), future research should be directed at the role of folate in the possible alleviation of VPA-induced NTD. It is also necessary to continue prospective studies to monitor the old and new AED prescribed and to evaluate the role of interactions between drugs used in combinations. [source]

    Clinical and Hemodynamic Effects of Nesiritide (B-Type Natriuretic Peptide) in Patients With Decompensated Heart Failure Receiving , Blockers

    William T. Abraham MD
    The use of , blockers in congestive heart failure presents a therapeutic challenge for patients with acute episodes of decompensation. Such patients may be less responsive to positive inotropic agents, whereas the beneficial effects of nesiritide, which are not dependent on the ,-adrenergic receptor signal-transduction pathway, may be preserved. This analysis of the Vasodilation in the Management of Acute CHF trial evaluated the safety and efficacy of nesiritide in decompensated congestive heart failure patients receiving , blockers. The Vasodilation in the Management of Acute CHF trial was a multicenter, randomized, controlled evaluation of nesiritide in 489 hospitalized patients with decompensated congestive heart failure. One hundred twenty-three patients were on chronic ,-blocker therapy at enrollment (31 randomized to placebo, 50 to nesiritide, and 42 to nitroglycerin). Primary end points included pulmonary capillary wedge pressure and dyspnea evaluation at 3 hours. Patients receiving nesiritide, but not IV nitroglycerin, had significantly reduced pulmonary capillary wedge pressure vs. placebo at 3 hours regardless of ,-blocker use. The use of , blockers did not alter the beneficial effects of nesiritide on systemic blood pressure, heart rate, or dyspnea evaluation. In nesiritide-treated subjects, safety profiles were similar regardless of ,-blocker use. Thus, the clinical and hemodynamic benefits and safety of nesiritide are preserved in decompensated congestive heart failure patients receiving chronic , blockade. [source]

    Monoclonal B cell lymphocytosis: Clinical and population perspectives,

    CYTOMETRY, Issue S1 2010
    Neil E. Caporaso
    Abstract Monoclonal B Cell Lymphocytosis (MBL) refers to clones of CLL-like cells that exhibit CLL characteristics that fall short of the numbers required for CLL diagnosis. Data from large CLL kindreds document increased prevalence of MBL suggesting a genetic contribution to its etiology. The molecular features that favor progression of MBL to CLL are poorly understood but an elevated B-cell count is a risk factor for progression. An important consideration when evaluating volunteers from CLL families who are willing to donate bone marrow is that MBL be ruled out since the MBL donor clone could result in a second CLL in the recipient. Further studies of MBL are needed to identify the molecular features and how they evolve during progression. Published 2010 Wiley-Liss, Inc. [source]

    The BSCC Code of Practice , exfoliative cytopathology (excluding gynaecological cytopathology)

    CYTOPATHOLOGY, Issue 4 2009
    A. Chandra
    Exfoliative cytopathology (often referred to as non-gynaecological cytology) is an important part of the workload of all diagnostic pathology departments. It clearly has a role in the diagnosis of neoplastic disease but its role in establishing non-neoplastic diagnoses should also be recognised. Ancillary tests may be required to establish a definitive diagnosis. Clinical and scientific teamwork is essential to establish an effective cytology service and staffing levels should be sufficient to support preparation, prescreening, on-site adequacy assessment and reporting of samples as appropriate. Routine clinical audit and histology/cytology correlation should be in place as quality control of a cytology service. Cytology staff should be involved in multidisciplinary meetings and appropriate professional networks. Laboratories should have an effective quality management system conforming to the requirements of a recognised accreditation scheme such as Clinical Pathology Accreditation (UK) Ltd. Consultant pathologists should sign out the majority of exfoliative cytology cases. Where specimens are reported by experienced biomedical scientists (BMS), referred to as cytotechnologists outside the UK, this must only be when adequate training has been given and be defined in agreed written local protocols. An educational basis for formalising the role of the BMS in exfoliative cytopathology is provided by the Diploma of Expert Practice in Non-gynaecological Cytology offered by the Institute of Biomedical Science (IBMS). The reliability of cytological diagnoses is dependent on the quality of the specimen provided and the quality of the preparations produced. The laboratory should provide feedback and written guidance on specimen procurement. Specimen processing should be by appropriately trained, competent staff with appropriate quality control. Microscopic examination of preparations by BMS should be encouraged wherever possible. Specific guidance is provided on the clinical role, specimen procurement, preparation and suitable staining techniques for urine, sputum, semen, serous cavity effusion, cerebrospinal fluid, synovial fluid, cyst aspirates, endoscopic specimens, and skin and mucosal scrapes.

    The Role of Clinical and Process Quality in Achieving Patient Satisfaction in Hospitals

    DECISION SCIENCES, Issue 3 2004
    Kathryn A. Marley
    ABSTRACT Managers constantly struggle with where to allocate their resources and efforts in managing the complex service delivery system called a hospital. In the broadest sense, their decisions and actions focus on two important aspects of health care,clinical or technical medical care that emphasizes "what" the patient receives and process performance that emphasizes "how" health care services are delivered to patients. Here, we investigate the role of leadership, clinical quality, and process quality on patient satisfaction. A causal model is hypothesized and evaluated using structural equation modeling for a sample of 202 U.S. hospitals. Statistical results support the idea that leadership is a good exogenous construct and that clinical and process quality are good intermediate outcomes in determining patient satisfaction. Statistical results also suggest that hospital leadership has more influence on process quality than on clinical quality, which is predominantly the doctors' domain. Other results are discussed, such as that hospital managers must be mindful of the fact that process quality is at least as important as clinical quality in predicting patient satisfaction. The article concludes by proposing areas for future research. [source]

    Clinical and histological alterations in the surrounding periodontium of dog's teeth submitted for an intrusive luxation

    Janaína Cristina Gomes
    An impact device was used on 12 teeth of six adult dogs with the purpose of making a dislocation on the long axis of these teeth. Of the teeth that suffer intrusion luxation, two did not receive treatment and ten were replaced by orthodontic extrusion with activated springs of 100 gf. The traction was initiated either immediately after the trauma or 7 days later. Observation time was 40 days. Endodontic therapy with calcium hydroxide was performed on the fourteenth day after the intrusive luxation. The intruded teeth that did not receive appropriate treatment had signs of extensive and progressive inflammatory resorption. The teeth that were moved immediately after the trauma had lesser degree of replacement resorption compared with those that were extruded 7 days after the trauma. [source]

    Immediate surgical repositioning following intrusive luxation: a case report and review of the literature

    H. Cem Güngör
    Abstract,,, This report presents a case of severe intrusive luxation of mature maxillary lateral incisor in a 10-year-old boy. The intruded tooth was immediately repositioned (surgical extrusion) and splinted within 2 h following injury. Tetracycline therapy was initiated at the time of repositioning and maintained for 10 days. Pulp removal and calcium hydroxide treatment of the root canal was carried out after repositioning. Splint was removed 1 month later. Definitive root canal treatment with gutta percha was accomplished at the second month recall. Clinical and radiographic examination 28 months after the surgical extrusion revealed satisfactory apical and periodontal healing. [source]

    Treatment of a severe dental lateral luxation associated with extrusion in an 8-month-old baby: a conservative approach

    Robson Frederico Cunha
    Abstract,,, This case report documents the trauma and follow-up care of lateral luxation associated with extrusion of the lower central incisors in an 8-month-old patient. The teeth were repositioned by digital pressure and stabilized using proximal sutures. Clinical and radiographic follow-up 40 months after the injury showed alterations in both incisors, but both remained functional and free of pathology. [source]

    Influence of the type of dental trauma on the pulp vitality and the time elapsed until treatment: a study in patients aged 0,3 years

    Daniela Maria Carvalho Pugliesi
    Abstract ,,,The purpose of the present study was to determine the influence of the type of trauma on the pulp vitality and the time elapsed until seeking dental care in children aged 0,3 years seen at the Baby Clinic of the Araçatuba Dental School, UNESP. A total of 1813 records were analyzed. Two hundred and three patients, corresponding to 302 traumatized teeth, were assessed clinically and radiographically. Hard-tissue injuries were the most frequent (52%), with a predominance of enamel crown fractures (41.4%), followed by concussions (12.6%) and intrusions (11.6%). Clinical and radiographic examination revealed that 72% of the traumatized teeth maintained pulp vitality. In the case of supporting-tissue lesions, 51.1% of the patients sought care within 1,15 days after injury, while in the case of hard-tissue injuries, 52.7% sought care only after 16 days. The results showed that supporting-tissue injuries had a significant influence on the faster seeking of dental care. [source]

    Healing of 208 intraalveolar root fractures in patients aged 7,17 years

    Miomir Cvek
    Abstract , This retrospective study consisted of 208 root-fractured, 168 splinted and 40 not splinted incisors in young individuals (aged 7,17 years) treated in the period 1959,1973 at the Pedodontic Department, Eastman Institute, Stockholm. Clinical and radiographic analyses showed that 69 teeth (33%) had developed hard tissue (fusion) healing of fragments. Interposition of periodontal ligament (PDL) and bone between the fragments was found in 17 teeth (8%). Interposition of PDL alone was found in 74 teeth (36%). Finally, non-healing with pulp necrosis and inflammatory changes between fragments was seen in 48 teeth (23%). Various clinical factors were analyzed for their relationship to the healing outcome with respect to healing/no healing and type of healing (hard tissue versus interposition of bone and/or PDL). Immature root and positive pulp sensitivity at time of injury was found to be significantly related to both pulp healing and hard tissue repair of the fracture. The same applied to concussion or subluxation of the coronal fragment compared to luxation with displacement (extrusive or lateral luxation). This relation was also represented by the variable millimeter diastasis between fragments before and after repositioning. Repositioning appeared to enhance the likelihood of both pulp healing and hard tissue repair. A positive effect of splinting, splinting methods (cap splints or orthodontic bands with an arch wire) or splinting periods could not be demonstrated on either pulp healing or type of healing (hard tissue versus interposition of bone and/or PDL). In conclusion, the findings from this retrospective study have cast doubts on the efficacy of long-term splinting and the types of splint used for root fracture healing. It is suggested that the role of splinting and splinting methods be examined in further studies. [source]

    Clinical and sociodemographic variables associated with the onset of posttraumatic stress disorder in road traffic accidents

    Ramón Coronas M.D.
    Abstract Our objective was to identify variables related to the onset of acute posttraumatic stress disorder (PTSD) after a road traffic accident. We evaluated 60 victims of a motor vehicle accident (MVA) in 2004 at 2 months postaccident. Thirty of them had developed PTSD; the other 30 had not developed PTSD. Clinical data, physical injuries, and sociodemographic characteristics were determined in 60 victims. The Davidson Trauma Scale (DTS) and a Structured Clinical Interview for DSM-IV (SCID) were used to evaluate PTSD occurrence. PTSD scores assessed by DTS and SCID at 2 months were significantly and positively associated with female sex, severe physical injuries, perceived social deprivation, and loss of job activity due to the accident. Female sex, severe physical injury, perceived social deprivation, and sick leave were related to the diagnosis of PTSD 2 months after the accident.

    Enhancing the Growth of Natural Eyelashes: The Mechanism of Bimatoprost-Induced Eyelash Growth

    2Article first published online: 2 APR 2010, JOEL L. COHEN MD
    BACKGROUND Many women desire prominent eyelashes. In December 2008, bimatoprost ophthalmic solution 0.03% was approved for the treatment of hypotrichosis of the eyelashes in the United States. OBJECTIVE To review eyelash physiology and the proposed mechanisms by which the topical pros-tamide product bimatoprost enhances eyelash growth. METHODS AND MATERIALS Clinical and preclinical studies pertaining to the efficacy, safety, and mechanisms of action of bimatoprost are presented. RESULTS Treatment with bimatoprost increases the percentage of eyelash follicles in anagen at any one time. This probably accounts for its ability to lengthen lashes. Bimatoprost-induced stimulation of melanogenesis appears to result in darker lashes and, at the same time, appears to increase the size of the dermal papilla and hair bulb, affecting lash thickness and fullness. Such effects, largely demonstrated in animal studies, are consistent with the results of a recent Food and Drug Administration phase III clinical trial. The favorable safety profile of bimatoprost in human subjects is probably secondary to the limited exposure of ocular tissues resulting from topical application at the base of the upper lashes. CONCLUSION By influencing the eyelash hair cycle and follicles, bimatoprost ophthalmic solution 0.03% is a safe and effective means of enhancing eyelash growth.

    Illicit substance use and its correlates in first episode psychosis

    R. Mazzoncini
    Mazzoncini R, Donoghue K, Hart J, Morgan C, Doody GA, Dazzan P, Jones PB, Morgan K, Murray RM, Fearon P. Illicit substance use and its correlates in first episode psychosis. Objective:, To determine if substance use (particularly cannabis) is more frequent among first episode psychosis patients and associated with a more problematic clinical presentation. Method:, All first episode psychosis (FEP) patients presenting to secondary services were recruited from London and Nottingham, over 2 years, in the Aetiology and Ethnicity of Schizophrenia and Other Psychoses study broad framework. Clinical and sociodemographic variables were assessed using a set of standardized instruments. A schedule was created to retrospectively collate substance use data from patients, relatives and clinicians. Results:, Five hundred and eleven FEP were identified. They used three to five times more substances than general population. Substance use was associated with poorer social adjustment and a more acute mode of onset. Cannabis use did not affect social adjustment, but was associated with a more acute mode of onset. Conclusion:, Cannabis has a different impact on FEP than other substances. Large epidemiological studies are needed to disentangle cannabis effect. [source]

MATERIAL AND METHODS Clinical, dermoscopic, and histopathologic examinations were performed for the occurrence of a 4-mm pigmented skin lesion on the hip of a 38-year-old Caucasian woman. RESULTS Dermoscopy examination of the lesion disclosed a stereotypical starburst pattern characterized by pigmented streaks symmetrically distributed at the periphery. A preoperative diagnosis of pigmented Spitz nevus was made, and the lesion was excised. However, subsequent histopathologic examination revealed a melanoacanthoma. CONCLUSION The starburst pattern, although diagnostic for pigmented Spitz nevus, can be rarely observed in other benign or malignant pigmented skin lesions. Accordingly, all lesions in adults exhibiting a starburst pattern or other spitzoid features should be excised for histopathologic evaluation. [source]

    Four-Year Follow-up on Endovascular Radiofrequency Obliteration of Great Saphenous Reflux

    Robert F. Merchant MD
    Background Endovascular radiofrequency obliteration has been used since 1998 as an alternative to conventional vein stripping surgery for elimination of saphenous vein insufficiency. Objective To demonstrate the long-term efficacy of this treatment modality. Methods Data were prospectively collected in a multicenter ongoing registry. Only great saphenous vein above-knee treatments were included in this study. Eight hundred ninety patients (1,078 limbs) were treated prior to November 2003 at 32 centers. Clinical and duplex ultrasound follow-up was performed at 1 week, 6 months, and 1, 2, 3, and 4 years. Results Among 1,078 limbs treated, 858 were available for follow-up within 1 week, 446 at 6 months, 384 at 1 year, 210 at 2 years, 114 at 3 years, and 98 at 4 years. The vein occlusion rates were 91.0%, 88.8%, 86.2%, 84.2%, and 88.8%, respectively; the reflux-free rates were 91.0%, 89.3%, 86.2%, 86.0%, and 85.7%, respectively; and the varicose vein recurrence rates were 7.2%, 13.5%, 17.1%, 14.0%, and 21.4%, respectively, at each follow-up time point at 6 months, and 1, 2, 3, and 4 years. Patient symptom improvement persisted over 4 years. Conclusions Endovascular temperature-controlled radiofrequency obliteration of saphenous vein reflux exhibits an enduring treatment efficacy clinically, anatomically, and hemodynamically up to 4 years following treatment.

    Clinical, Histologic, and Ultrastructural Changes after Nonablative Treatment with a 595-nm Flashlamp-Pumped Pulsed Dye Laser: Comparison of Varying Settings

    David J. Goldberg MD
    Background. The flashlamp-pulsed dye laser has been used for nonablative dermal remodeling. Objective. We conducted a study analyzing the clinical, histologic, and electron microscopic findings after treatment with different flashlamp-pulsed dye laser settingss in the same subject. Results. Most subjects showed mild to moderate improvement after flashlamp-pulsed dye laser laser treatment. There was no statistical difference in the clinical, histologic, or electron microscopic findings with a variety of laser treatment settings. Conclusion. Nonablative dermal remodeling can be accomplished with not only a variety of different technologies, but also with the same laser using markedly different settings. [source]

    A Case of Multiple Keratoacanthoma Centrifugum Marginatum

    Cristina Mangas MD
    Background. Keratoacanthoma centrifugum marginatum is a rare variety of keratoacanthoma, usually presented and classified as solitary keratoacanthoma. Reported cases of multiple keratoacanthoma centrifugum marginatum are exceptional in the literature. Observations. A 21-year-old man presented for evaluation of erythematous papules and plaques on both legs that had had a peripheral growth over the past year. Clinical and histologic examination showed typical features of keratoacanthoma centrifugum marginatum. Owing to the multiplicity and size of the lesions, treatment with oral isotretinoin was started. It was ineffective. Subsequent treatment with methotrexate combined with oral prednisone led to the regression of all lesions. Conclusions. The exceptional case of a man with multiple keratoacanthoma centrifugum marginatum is reported. Treatment with methotrexate combined with oral prednisone was effective. This case illustrates how some variants of keratoacanthomas do not really fit into the current classification and how complex the treatment of these tumors is. [source]

    Comparison of Long-Pulsed Diode and Long-Pulsed Alexandrite Lasers for Hair Removal: A Long-Term Clinical and Histologic Study

    Christiane Handrick MD
    Background. Unwanted facial and body hair is a common problem, generating a high level of interest for treatment innovations. Advances in laser technology over the past several years has led to the development and distribution of numerous red and infrared lasers and light sources to address this issue. Despite the impressive clinical results that have been reported with the use of individual laser hair removal systems, long-term comparative studies have been scarce. Objective. To compare the clinical and histologic efficacy, side effect profile, and long-term hair reduction of long-pulsed diode and long-pulsed alexandrite laser systems. Methods. Twenty women with Fitzpatrick skin types I,IV and dark terminal hair underwent three monthly laser-assisted hair removal sessions with a long-pulsed alexandrite laser (755 nm, 2-msec pulse, 10 mm spot) and a long-pulsed diode laser (800 nm, 12.5 msec or 25 msec, 9 mm spot). Axillary areas were randomly assigned to receive treatment using each laser system at either 25 J/cm2 or 40 J/cm2. Follow-up manual hair counts and photographs of each area were obtained at each of the three treatment visits and at 1, 3, and 6 months after the final laser session. Histologic specimens were obtained at baseline, immediately after the initial laser treatment, and 1 and 6 months after the third treatment session. Results. After each laser treatment, hair counts were successively reduced and few patients found it necessary to shave the sparsely regrown hair. Optimal clinical response was achieved 1 month after the second laser treatment, regardless of the laser system or fluence used. Six months after the third and final treatment, prolonged clinical hair reduction was observed with no significant differences between the laser systems and fluences used. Histologic tissue changes supported the clinical responses observed with evidence of initial follicular injury followed by slow follicular regeneration. Side effects, including treatment pain and vesiculation, were rare after treatment with either laser system, but were observed more frequently with the long-pulsed diode system at the higher fluence of 40 J/cm2. Conclusion. Equivalent clinical and histologic responses were observed using a long-pulsed alexandrite and a long-pulsed diode laser for hair removal with minimal adverse sequelae. While long-term hair reduction can be obtained in most patients after a series of laser treatments, partial hair regrowth is typical within 6 months, suggesting the need for additional treatments to improve the rate of permanent hair removal.

    The Efficacy of EMLA versus ELA-Max for Pain Relief in Medium-Depth Chemical Peeling: A Clinical and Histopathologic Evaluation

    Robert A. Koppel MD
    Background. Medium-depth chemical peels are an effective and popular treatment for actinic damage, fine wrinkles, and pigmentary dyschromias. However, they are also uncomfortable. A previous attempt to study the effectiveness of a topical anesthetic gel in 35% trichloroacetic acid (TCA) peeling found a reduction in discomfort but an increased depth of penetration and delayed healing. Objective. To evaluate both the efficacy of two topical anesthetic agents in medium-depth combination peeling as well as the histologic result from chemical peeling combined with topical anesthesia. Method. Seventy percent glycolic acid (GA) was applied to the entire face of 10 patients and diluted with water after 2 minutes. This was followed by the sequential application of EMLA cream (lidocaine 2.5% and prilocaine 2.5%), ELA-Max cream (lidocaine 4%), and placebo to selected areas on the face for 30 minutes without occlusion. These agents were then removed and 35% TCA was applied to the entire face. The level of discomfort felt by the patients during the TCA peel was recorded, clinical photographs were taken, and bilateral preauricular biopsies were performed at baseline, 48 hours, and 90 days postoperatively. Results. Clinically there was a statistically significant decrease in pain felt during the 70% GA-35% TCA peel with topical anesthesia when compared to the control. There was no statistically significant difference in efficacy between EMLA and ELA-Max. There was also no difference in either the clinical or the histopathologic appearance between the medium-depth peel combined with topical anesthesia and the medium-depth peel with control. Conclusion. Both EMLA and ELA-Max decrease the discomfort felt during medium-depth combination chemical peeling without influencing either the clinical or the histopathologic result. [source]

    Clinical and serotonergic predictors of non-affective acute remitting psychosis in patients with a first-episode psychosis

    B. Arranz
    Objective:, The study aimed to establish clinical predictors of non-affective acute remitting psychosis (NARP) and assess whether these patients showed a distinct serotonergic profile. Method:, First-episode never treated psychotic patients diagnosed of paranoid schizophrenia (n = 35; 21 men and 14 women) or NARP (n = 28; 15 men and 13 women) were included. Results:, NARP patients showed significantly lower negative symptomatology, better premorbid adjustment, shorter duration of untreated psychosis, more depressive symptomatology and a lower number of 5-HT2A receptors than the paranoid schizophrenia patients. In the logistic regression, the four variables associated with the presence of NARP were: low number of 5-HT2A receptors; good premorbid adjustment; low score in the item ,hallucinatory behaviour' and reduced duration of untreated psychosis. Conclusion:, Our findings support the view that NARP is a highly distinctive condition different from either affective psychosis or other non-affective psychosis such as schizophrenia, and highlight the need for its validation.

    Assessment of cerebral visual impairment with the L94 visual perceptual battery: clinical value and correlation with MRI findings

    In this article we describe visual perceptual abilities of a clinical population, referred for visual problems to our multidisciplinary team and assessed with the five computer tasks from the L94 visual perceptual battery. Clinical and neuroimaging findings were correlated with the findings on this task battery. Seventy children (35 males, 35 females) constituted our cohort. Age ranged from 4 to 20 years (mean 7y [SD 3y]). Forty children were born before 37 weeks gestational age. Thirty-six children had cerebral palsy (CP), of whom 24 had spastic diplegia, five had spastic hemiplegia, and four had spastic quadriplegia. Three children had ataxic CP. Perceptual visual impairment (PVI) was established in comparison to the performance age obtained on non-verbal intelligence subtests, instead of chronological age. Our results suggest that children with a history of preterm birth and a clinical CP picture are most at risk for a specific PVI. Correlations among other clinical variables did not define a clinical subgroup more at risk. Children with periventricular leucomalacia were almost equally represented in both PVI and non-PVI groups. Normal magnetic resonance imaging did not exclude the presence of PVI. In these children, however, we found another impairment profile, more in favour of dorsal stream impairment. [source]

    Clinical and Economic Factors Associated with Ambulance Use to the Emergency Department

    Jennifer Prah Ruger PhD
    Background: Concern about ambulance diversion and emergency department (ED) overcrowding has increased scrutiny of ambulance use. Knowledge is limited, however, about clinical and economic factors associated with ambulance use compared to other arrival methods. Objectives: To compare clinical and economic factors associated with different arrival methods at a large, urban, academic hospital ED. Methods: This was a retrospective, cross-sectional study of all patients seen during 2001 (N= 80,209) at an urban academic hospital ED. Data were obtained from hospital clinical and financial records. Outcomes included acuity and severity level, primary complaint, medical diagnosis, disposition, payment, length of stay, costs, and mode of arrival (bus, car, air-medical transport, walk-in, or ambulance). Multivariate logistic regression identified independent factors associated with ambulance use. Results: In multivariate analysis, factors associated with ambulance use included: triage acuity A (resuscitation) (adjusted odds ratio [OR], 51.3; 95% confidence interval [CI] = 33.1 to 79.6) or B (emergent) (OR, 9.2; 95% CI = 6.1 to 13.7), Diagnosis Related Group severity level 4 (most severe) (OR, 1.4; 95% CI = 1.2 to 1.8), died (OR, 3.8; 95% CI = 1.5 to 9.0), hospital intensive care unit/operating room admission (OR, 1.9; 95% CI = 1.6 to 2.1), motor vehicle crash (OR, 7.1; 95% CI = 6.4 to 7.9), gunshot/stab wound (OR, 2.1; 95% CI = 1.5 to 2.8), fell 0,10 ft (OR, 2.0; 95% CI = 1.8 to 2.3). Medicaid Traditional (OR, 2.0; 95% CI = 1.4 to 2.4), Medicare Traditional (OR, 1.8; 95% CI = 1.7 to 2.1), arrived weekday midnight,8 AM (OR, 2.0; 95% CI = 1.8 to 2.1), and age ,65 years (OR, 1.3; 95% CI = 1.2 to 1.5). Conclusions: Ambulance use was related to severity of injury or illness, age, arrival time, and payer status. Patients arriving by ambulance were more likely to be acutely sick and severely injured and had longer ED length of stay and higher average costs, but they were less likely to have private managed care or to leave the ED against medical advice, compared to patients arriving by independent means.

    Proximal femoral resection for subluxation or dislocation of the hip in spastic quadriplegia

    Steve Ackerly MD
    Management of a painful or contracted hip dislocation in individuals with severe spastic quadriplegia is difficult. Clinical and radiographic results of 12 proximal femoral resection-interposition operations performed in seven non-ambulatory persons (five males, two females; mean age 14 years, 8 months; age range 6 years 11 months to 19 years 8 months) with severe spasticity were reviewed to determine if pain relief and restoration of motion were maintained. At a mean follow-up of 7 years 7 months (median 9 years 6 months) all participants maintained a good sitting position and a functional range of motion with improved hygiene. Hip pain was improved in all participants compared with their preoperative status. Proximal femur migration occurred causing slight pain in one person. Heterotopic ossification was observed but was not clinically significant. Complications included traction pin loosening and infection and a late supracondylar femur fracture 3 months after the operation. Proximal femoral resection effectively decreased pain and restored hip motion in those with severe spastic quadriplegia leading to improved sitting and perineal care. [source]

    The Canadian National Outcomes Measurement Study in Schizophrenia: overview of the patient sample and methodology

    G. Smith
    Objective:, The Canadian National Outcomes Measurement Study in Schizophrenia (CNOMSS) is a prospective survey of routine clinical practice. Method:, Patients with schizophrenia or a related disorder were consecutively enrolled from all regions of Canada. Both academic and community psychiatric clinics were included and patients were followed up for 2 years. Clinical and functional status, quality of life, medication and economic costs were assessed at enrollment and monitored throughout the follow-up period. Results:, Patients attending an academic clinic tended to be younger and more severely ill than those from community clinics. Both types of sites prescribed atypical neuroleptics to more than three-quarters of the patients. The majority of those enrolled were unemployed and living in poverty. Poor clinical status was associated with poverty. Conclusion:, The CNOMSS provides demographic, clinical and treatment-related information about a large Canada-wide sample of psychiatric patients. The following three articles in this issue of Acta Psychiatrica Scandinavica explore issues related to medication, quality of life and resource utilization. [source]

    Papillary thyroid carcinoma with metastasis to the frontal skull

    Dian Feng M.D., Ph.D.
    Abstract Papillary thyroid carcinoma with metastasis to the frontal skull is extremely rare. We report a case of unsuspected papillary thyroid carcinoma with frontal skull metastasis. The patient was a 62-year-old African American woman with presentation of a 4-cm firm, painless, immobile, ill-defined mass at the right forehead. Ultrasound and computer tonography detected a hypervascular and osteolytic tumor involving the skull and overlying skin. Fine-needle aspiration was performed followed by surgical biopsy. Cytologic examination revealed the presence of hypercellular and bloody material. The neoplasm showed glandular features and was composed of clusters of round to oval cells with pinkish squamoid cytoplasm, oval nuclei and inconspicuous nucleoli on smears and sections of cell block. With immunocytochemical stain, the neoplastic cells were positive for pancytokeratin and vimentin and focally positive for EMA, while they were negative for S100, HMB45, Melan-A, CD34, GFAP, CD10, LCA, RCC and CD138. The diagnosis was a metastatic carcinoma. Clinical follow up with surgical biopsy was recommended. Surgical biopsy demonstrated histological and cytological features of papillary thyroid carcinoma including prominent papillae, nuclear overlapping, grooves, and intranuclear pseudoinclusions. Thus, a diagnosis of metastatic papillary thyroid carcinoma was rendered. Though skull metastasis of thyroid carcinoma is rare, it should be considered in the differential diagnosis when a skull mass lesion is encountered. Diagn. Cytopathol. 2009. © 2009 Wiley-Liss, Inc.
