Published 1995Staff ViewISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract: Biosensors sensitive for in vivo monitoring of serotonin (5-HT) in the CNS by differential normal pulse voltammetry were constructed by coating treated multi-carbon fiber electrodes (mCFEs) with Nafion (N-mCFE). In vitro sensitivities of mCFE and N-mCFE were compared in solutions ranging from 5 nM to 20 µM of uric acid (UA), 5-hydroxyindoleacetic acid (5-HIAA), and 5-HT. The mCFEs were three to seven times less sensitive for 5-HIAA or UA than for 5-HT. Nafion treatment dramatically decreased sensitivity for 5-HIAA and UA of N-mCFEs (∼103 times), whereas it remained in the nanomolar range for 5-HT. In vivo, in the dorsal horn of the lumbar spinal cord of anesthetized rats, the monoamine oxidase inhibitor clorgyline (10 mg/kg i.p.) produced a reduction (55 ± 3% at 180 min) of peak 3 of oxidation current (characteristic of 5-hydroxyindoles) monitored with mCFEs, but with N-mCFEs (in this latter case the peak was termed 3N) peak 3N increased to 135 ± 5% at 180 min. The 5-HT release-inducer p-chloroamphetamine (PCA; 6 mg/kg i.p.) induced a slight (12 ± 3% at 150 min) decrease in peak 3 measured with mCFEs, whereas with N-mCFEs PCA induced a rapid increase of peak 3N (137 ± 6% at 90 min). The xanthine oxidase inhibitor allopurinol (10 mg/kg i.p.) produced a decrease (30 ± 3% at 180 min) in peak 3 (mCFEs), but peak 3N (N-mCFEs) was not affected (106% at 180 min). After pretreatment with allopurinol, PCA also produced an increase (135 ± 6% at 90 min) in peak 3N. These in vitro and in vivo data provide evidence for a highly preferential detection of 5-HT versus 5-HIAA and UA by N-mCFEs, which could be used to follow the extracellular 5-HT concentration within very discrete structures throughout the CNS.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background Xeroderma pigmentosum (XP) is a rare disorder produced by a genetic defect in the repair of DNA damage caused by ultraviolet radiation. The early diagnosis of malignant skin tumours is crucial in the survival of patients with XP, but this is not easy even for experienced dermatologists due to the presence of a high number of actinic lesions. Dermoscopy is a new diagnostic method that increases the diagnostic accuracy for skin tumours.Objectives To describe the clinical and dermoscopic features of different benign and malignant lesions [focusing on malignant melanoma, basal cell carcinoma (BCC) and benign melanocytic naevi] in two patients with XP.Methods Three dermatologists with experience in pigmented skin lesions and dermoscopy examined two siblings with XP over a period of 54 months. Diagnosis of skin tumours was obtained using clinical examination and dermoscopy with 10-fold magnification and digital images. All the tumours with criteria of malignancy were excised for further histopathological analyses.Results Multiple skin tumours showing some degree of pigmentation were detected in the patients. Clinical and dermoscopic examination allowed the discrimination of four melanomas (three of them in situ), 26 BCCs and five dysplastic naevi from other pigmented skin lesions. The features and parameters previously described for dermoscopy were shown to be appropriate for the recognition of tumours in our patients with XP. Generalized actinic lentigos were distinguished from BCCs by the presence of a delicate brown pigmented network. Fine vessels from poikiloderma were differentiated from the arborizing telangiectasia of BCC.Conclusions The dermoscopic findings in the tumours were similar to those previously described in patients not affected by XP. Diagnosis by dermoscopic pattern analyses allowed a correct classification of malignant tumours in these cases.Type of Medium: Electronic ResourceURL: -

Published 2004Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background Benign melanocytic skin lesions may be difficult to differentiate from melanoma both clinically and dermoscopically. One of the most confounding dermoscopic features, commonly seen in melanoma but in our experience also in melanocytic naevi, is represented by the so-called blue–white structures (BWS).Objectives To evaluate diagnostic significance and histopathological correlates of BWS seen by dermoscopy in a series of clinically equivocal melanocytic skin lesions that were excised.Methods Patients were recruited from six specialized pigmented lesion clinics in Austria, Italy and Spain over a period of 9 months. All consecutive patients showing one or more melanocytic lesions with BWS, but not classified as melanoma dermoscopically, were included. Each lesion was photographed clinically and dermoscopically. All images were reviewed by one of us and the degree, type and location of BWS evaluated for each lesion. A panel of four experienced dermatopathologists independently reviewed all specimens for diagnosis and one of them evaluated presence and degree of melanosis and/or fibrosis. The main outcome measures were the percentage and histopathological correlates of lesions with different degree, type and location of BWS.Results All included lesions with BWS (n = 158) showed partial or focal regression histopathologically. One hundred and thirty-five (85·4%) lesions were diagnosed as melanocytic naevi (complete histopathological interobserver agreement), whereas 23 (14·6%) were defined as equivocal because at least one of four pathologists diagnosed the given lesion as melanoma. Only one lesion was diagnosed as melanoma by all four pathologists. The majority of naevi exhibited blue areas (84·4%) with a central distribution (57%) and involving 〈 50% of the lesion surface (89·6%). By contrast, 78·3% of equivocal lesions revealed a combination of white and blue areas with an irregular distribution (60·9%) and involving 〉 50% of the lesion surface (47·8%).Conclusions Using degree and type of BWS, an algorithm was constructed that can be applied for the management of lesions exhibiting dermoscopic features of regression.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The association of two different neoplasms in the same lesion is uncommon and has been reported as collision or compound tumours in the medical literature. In cases where a malignant neoplasm exists in association with a benign lesion it is important to make an accurate diagnosis in order to treat the lesions correctly. Dermoscopy is an in vivo, noninvasive technique that improves the clinical accuracy in diagnosing melanoma and other pigmented skin lesions. We describe the dermoscopic characteristics of various collision or compound tumours that were composed of benign and malignant neoplasms: two cases of seborrhoeic keratosis associated with basal cell carcinoma, two cases of melanocytic naevus and basal cell carcinoma and one case of dermatofibroma associated with basal cell carcinoma. We conclude that dermoscopy is a useful tool for improving the recognition of these kinds of tumours.Type of Medium: Electronic ResourceURL: -

Published 2004Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background Dermoscopy improves the diagnostic accuracy in pigmented skin lesions, but it is also useful in the evaluation of nonpigmented skin tumours as it allows the recognition of vascular structures that are not visible to the naked eye. Bowen's disease (BD) or squamous cell carcinoma in situ is usually nonpigmented, but may also rarely be pigmented.Objective To describe the dermoscopic features in a series of pigmented and nonpigmented BD.Methods Dermoscopic images of 21 histopathologically proven BD were evaluated for the presence of various dermoscopic features. Each lesion was photographed using the Dermaphot (Heine Optotechnik, Herrsching, Germany), at 10-fold magnification, and the colour slides were scanned to digital format using a Kodak Photo CD system.Results The majority of cases of BD revealed a peculiar dermoscopic pattern characterized by glomerular vessels (90%) and a scaly surface (90%). In addition, in pigmented BD small brown globules regularly packed in a patchy distribution (90%), and structureless grey to brown pigmentation (80%) were observed.Conclusions Dermoscopy can be helpful for diagnosing BD because of the presence of repetitive morphological findings such as glomerular vessels and a scaly surface. In pigmented BD, small brown globules and/or homogeneous pigmentation can be seen as well.Type of Medium: Electronic ResourceURL: -

The CDKN2A gene has been described as responsible for melanoma susceptibility in a proportion of families with CMM linked to 9p. CDKN2A encodes a cyclin-dependent kinase inhibitor also implicated in the carcinogenesis of several sporadic tumors. Even though the incidence of other cancers is higher in CMM families, pancreatic adenocarcinoma is the only other well demonstrated cancer associated with CDKN2A mutations in some CMM pedigrees. We describe a family with four cases of CMM, eight patients affected by other cancers, and nine patients affected by dysplastic nevus (DN) syndrome. A CDKN2A frameshift mutation (358delG) was present in all the CMM patients, in at least three of the patients with other cancers (CDKN2A status is unknown in four patients), and in only two of the DN patients (CDKN2A status is unknown in one patient). An absence of linkage between chromosome 9p markers and the 358delG CDKN2A mutation and DN was detected, indicating genetic heterogeneity for DN and CMM in this family. The study strongly suggests that CDKN2A mutations are involved not only in the predisposition to CMM but also to several other types of cancer.Type of Medium: Electronic ResourceURL: -

Profound knowledge of the normal chest X-ray and the potential physiological perinatal changes is the basic requirement for interpretation of the X-ray of a neonate. Childhood pathologie: Many congenital and acquired diseases that the radiologist is faced with in neonatology are unknown in the imaging of adults. Many of these changes are life-threatening or may have an impact on the patient’s future quality of life. Therefore early diagnosis in close cooperation with the paediatrician is essential. We give here an overview of the most important pathologic changes that the radiologist may be con- fronted with in daily routine.Notes: Zusammenfassung In der bildgebenden Diagnostik thorakaler Pathologien bei reifen und insbesondere unreifen Neugeborenen steht das Thoraxröntgenbild an erster Stelle.

Kindliche Pathologien: Eine Vielzahl von kongenitalen und erworbenen Veränderungen, mit denen der Radiologe in der Neonatologie konfrontiert ist, sind in der Radiodiagnostik des erwachsenen Patienten unbekannt. Viele dieser Veränderungen sind für den Patienten lebensbedrohlich oder können die Lebensqualität in seinem weiteren Leben beeinflussen. Eine frühzeitige Diagnostik in enger Zusammenarbeit mit dem Pädiater ist daher essenziell. Hier wird ein Überblick über die wichtigsten Pathologien, mit denen der Radiologe in der täglichen Routine konfrontiert sein kann, gegeben.Type of Medium: Electronic ResourceURL: -

Better prognosis of childhood tumors, due to better biological understanding and improvement of chemotherapy, require sufficient radiological staging. Sufficiency in radiological staging needs modern cross-sectional techniques with high resolution, good availability and lower radiation dose. In general computed tomography (CT) is being used for radiological staging; increasingly MR imaging is being used because of multiplanar imaging techniques. Replacement of invasive techniques such as myelography and lymphography and modern cross-sectional techniques create painless staging conditions. Nevertheless, scintigraphy will always be a major examination technique, especially for evaluation of metastases and postoperative control examinations. The most common thoracoabdominal tumors in childhood and their staging are described.Notes: Zusammenfassung Thorakale und abdominale Tumoren im Kindesalter nehmen ihren Ausgang von allen Organsystemen und können vom Neugeborenen bis zum Adoleszenten auftreten. Verbesserte Prognose, bedingt durch das bessere biologische Verständnis der Tumorerkrankung, sowie der effiziente Einsatz von Chemotherapeutika machen ein radiologisches Staging unumgänglich. Üblicherweise wird zum Staging die Computertomographie (CT) eingesetzt. Durch die Möglichkeit der multiplanaren Schnittführung und die bessere Auflösung bei Tumoren mit Beteiligung des ZNS wird in zunehmendem Maße die Magnetresonanztomographie (MRT) eingesetzt. Diese modernsten Schnittbildverfahren haben invasive Methoden wie Lymphographie und Angiographie in den Hintergrund gedrängt. Im weiteren werden die häufigsten thorakalen und abdominalen Tumoren im Kindesalter besprochen und deren Stagingsysteme erläutert.Type of Medium: Electronic ResourceURL: -

Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclininal, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed.Notes: Zusammenfassung Ein Infarkt im Stromgebiet der Zerebralarterien stellt eine wichtige Differentialdiagnose bei neurologischen Auffälligkeiten in der Neonatalperiode dar. Die Inzidenz wird anhand von klinischer Daten auf 1:4000 Lebendgeborene geschätzt. Da der Verlauf oft subklinisch ist, liegt die wahre Inzidenz wahrscheinlich höher. Diagnose: Bei der Diagnosestellung kommen dem Schädelultraschall und der Dopplersonographie als leicht verfügbaren Screening-Methoden eine zentrale Rolle zu. Die definitive Diagnose wird, je nach Verfügbarkeit, mittels Computertomographie oder Kernspintomographie gestellt. Die Behandlung ist neben der symptomatischen (antikonvulsiven) Therapie auf die Vermeidung von ischämischen Sekundärschäden gerichtet. Diskussion: Wir wollen mit der vorliegenden Arbeit anhand von 3 Kindern mit verschiedenen klinischen Verläufen eines sog. Neonatal stroke den Stellenwert der bildgebenden Verfahren bei der Diagnostik und Verlaufskontrolle aufzeigen und die Sensibilität für dieses vermutlich unterdiagnostizierte Krankheitsbild erhöhen.Type of Medium: Electronic ResourceURL: -

Dislocations and septic and thromboembolic complications may occur. Control of position: Radiologically, the correct position of the catheter must be proven. Dislocations or complications associated with central catheters must be diagnosed. For catheter monitoring plain film radiographs are the first line of investigation; however, sonography may be of additional assistance. Angiographic techniques should only be performed when conventional noninvasive methods do not supply satisfactory results. Special knowledge is necessary for monitoring catheters that are set via the umbilical artery or vein. The radiological applications for catheter monitoring in the neonate intensive care unit are discussed in this article.Notes: Zusammenfassung Hintergrund: Die im neonatologischen Krankengut am häufigsten verwendeten Zugänge sind Katheter, die eine prolongierte Verabreichung von Antibiotika, höher osmolarer Lösungen oder evtl. Chemotherapeutika gewährleisten. Komplikationen ergeben sich durch Fehllagen oder sind septischer und thrombembolischer Genese. Lagekontrolle: Für den Radiologen gilt es, eine adäquate Lagekontrolle des Katheters durchzuführen, um Fehllagen zu vermeiden, jedoch auch Komplikationen zu diagnostizieren. Für dieses Kathetermonitoring steht zur Lagekontrolle das Nativbild im Vordergrund, des Weiteren erweist sich jedoch die Sonographie als wesentlicher Pfeiler in der Katheterdiagnostik, insbesondere im Hinblick auf die katheterassoziierten Komplikationen. Angiographische Techniken sollten erst nach Ausschöpfen sämtlicher nichtinvasiver diagnostischer Möglichkeiten durchgeführt werden. Besondere Anforderungen ergeben sich durch die in der Neonatologie verwendeten Zugänge über den Nabel, wobei sowohl Kenntnis der exakten Topographie der Katheterlage als auch der speziellen potentiellen Komplikationen von großer Bedeutung ist. Im Folgenden sollen die radiologischen Aufgaben und Möglichkeiten beim Kathetermonitoring unter besonderer Berücksichtigung spezieller Anforderungen bei neonatologischen Intensivpatienten vorgestellt werden.Type of Medium: Electronic ResourceURL: -

In general, plain radiography of the abdomen and sonography are valuable imaging techniques for diagnosis of NEC. Course of NEC: The disease starts with distension of small bowel loops. Furthermore the children develop pneumatosis in the bowel wall, which is a nonspecific pattern. If the NEC persists, the air passes into the portal vein system, causing a pneumoportogram. Finally, the disease can lead to perforation. In doubtful cases, the plain radiogram must be repeated within a period of 6 h. With sonography distension of the bowel, thickening of and pneumatosis in the bowel wall, the pneumoportogram and free intraperitoneal fluid can be easily depicted. The most common complications of NEC are intestinal stenosis and strictures that can lead to ileus. Differential diagnosis: Focal perforation of ileum, volvulus and Hirschsprung’s disease are some of the differential diagnoses.Notes: Zusammenfassung Die nekrotisierende Enterokolitis (NEC) ist eine schwere Erkrankung des Abdomens bei Frühgeborenen, die einer raschen, nötigenfalls chirurgischen Therapie zugeführt werden muss. Dazu bedarf es einer frühen Diagnose, die mit einer Leeraufnahme des Abdomens und Sonographie gestellt werden kann. Verlauf von NEC: Die NEC beginnt mit einer Dilatation des Darms, zumeist des Dünndarms, in 2. Linie des Dickdarms. Des Weiteren entwickeln sich stehende Schlingen und eine Pneumatosis intestinalis, die ein unspezifisches Zeichen ist und bei allen ischämischen Darmerkrankungen auftreten kann. Beim Fortschreiten der Erkrankung kommt es zum Pneumoportogramm und im schlimmsten Fall zur Perforation. Bei unklaren Abdomenleerbefunden ist eine engmaschige radiologische Kontrolle notwendig. Sonographisch können sowohl die Distension des Darms als auch die Pneumatosis intestinalis als auch das Pneumoportogramm als auch freie Flüssigkeit hervorragend erfasst werden. Spätkomplikationen sind Stenosen und Strikturen, die zu Subileus und Ileus führen können. Differentialdiagnosen: Die Differentialdiagnosen reichen von fokaler Ileumperforation bis hin zu Volvulus und Morbus Hirschsprung.Type of Medium: Electronic ResourceURL: -
