Quantification of Orbital Apex Crowding for Screening of Dysthyroid Optic Neuropathy Using Multidetector CT

BACKGROUND AND PURPOSE: DON, a serious complication of GO, is frequently difficult to diagnose clinically in its early stages because of confounding signs and symptoms of congestive orbitopathy. We evaluated the ability of square area measurements of orbital apex crowding, calculated with MDCT, to detect DON. MATERIALS AND METHODS: Fifty-six patients with GO were studied prospectively with complete neuro-ophthalmologic examination and MDCT scanning. Square measurements were taken from coronal sections 12 mm, 18 mm, and 24 mm from the interzygomatic line. The ratio between the extraocular muscle area and the orbital bone area was used as a Cl. Intracranial fat prolapse through the superior orbital fissure was recorded as present or absent. Severity of optic nerve crowding was also subjectively graded on corona! images. Orbits were divided into 2 groups (with or without clinical evidence of DON) and compared. RESULTS: Ninety-five orbits (36 with and 59 without DON) were studied. The CIs at all 3 levels and the subjective crowding score were significantly greater in orbits with DON (P<.001). No significant difference was observed regarding intracranial fat prolapse (P=.105). The area under the ROC curves was 0.91, 0.93, and 0.87 for CIs at 12, 18, and 24 mm, respectively. The best performance was at 18 mm, where a cutoff value of 57.5% corresponded to 91.7% sensitivity, 89.8% specificity, and an odds ratio of 97.2 for detecting DON. A significant correlation (P<.001) between the CIs and VF defects was observed. CONCLUSIONS: Orbital Cls based on area measurements were found to predict DON more reliably than subjective grading of orbital crowding or intracranial fat prolapse.

Metabolic profile of dystrophic mdx mouse muscles analyzed with in vitro magnetic resonance spectroscopy (MRS)

Duchenne muscular dystrophy (DMD) is a recessive X-linked form of muscular dystrophy characterized by progressive and irreversible degeneration of the muscles. The mdx mouse is the classical animal model for DMD, showing similar molecular and protein defects. The mdx mouse, however, does not show significant muscle weakness, and the diaphragm muscle is significantly more degenerated than skeletal muscles. In this work, magnetic resonance spectroscopy (MRS) was used to study the metabolic profile of quadriceps and diaphragm muscles from mdx and control mice. Using principal components analysis (PCA), the animals were separated into groups according to age and lineages. The classification was compared to histopathological analysis. Among the 24 metabolites identified from the nuclear MR spectra, only 19 were used by the PCA program for classification purposes. These can be important key biomarkers associated with the progression of degeneration in mdx muscles and with natural aging in control mice. Glutamate, glutamine, succinate, isoleucine, acetate, alanine and glycerol were increased in mdx samples as compared to control mice, in contrast to carnosine, taurine, glycine, methionine and creatine that were decreased. These results suggest that MRS associated with pattern recognition analysis can be a reliable tool to assess the degree of pathological and metabolic alterations in the dystrophic tissue, thereby affording the possibility of evaluation of beneficial effects of putative therapies.

Renal function evaluation in patients with American Cutaneous Leishmaniasis after specific treatment with pentavalent antimonial

Background: Renal evaluation studies are rare in American Cutaneous Leishmaniasis (ACL). The aim of this study is to investigate whether specific treatment reverts ACL-associated renal dysfunction. Methods: A prospective study was conducted with 37 patients with ACL. Urinary concentrating and acidification ability was assessed before and after treatment with pentavalent antimonial. Results: The patients mean age was 35.6 +/- 12 years and 19 were male. Before treatment, urinary concentrating defect (U/P-osm < 2.8) was identified in 27 patients (77%) and urinary acidification defect in 17 patients (46%). No significant glomerular dysfunction was observed before and after specific ACL treatment. There was no reversion of urinary concentrating defects, being observed in 77% of the patients before and in 88% after treatment (p = 0.344). Urinary acidification defect was corrected in 9 patients after treatment, reducing its prevalence from 40% before to only 16% after treament, (p = 0.012). Microalbuminuria higher than 30 mg/g was found in 35% of patients before treatment and in only 8% after treatment. Regarding fractional excretion of sodium, potassium, calcium, phosphorus and magnesium, there was no significant difference between pre and post-treatment period. Conclusion: As previously described, urinary concentrating and acidification defects were found in an important number of patients with ACL. Present results demonstrate that only some patients recover urinary acidification capacity, while no one returned to normal urinary concentration capacity.

Second-trimester soft markers: relation to first-trimester nuchal translucency in unaffected pregnancies

Objective Genetic sonography following first-trimester combined screening appears to increase substantially detection rates for Down syndrome but it relies on the unproved assumption of independence between these tests. In this study we aimed to investigate the relationship between first-trimester nuchal translucency (NT) and a series of second-trimester soft markers and structural defects in unaffected pregnancies. Methods NT measurement in the first trimester was followed by second-trimester scan (18 to 23 + 6 weeks) including examination for three categorical markers (intracardiac echogenic foci, hyperechogenic bowel and structural defects) and measurement of nasal bone length, nuchal-fold thickness, femur length, humerus length, renal pelvis diameter and prenasal thickness. All continuous variables were expressed in multiples of the median (MoM) for gestation and correlation coefficients between log-transformed NT and second-trimester variables were calculated. In addition, frequencies of soft markers and structural defects in cases with increased NT were compared to those with normal NT, using MoM cut-offs. Results In a dataset of 1970 cases, NT was significantly correlated (P < 0.05) with all second-trimester continuous variables, the correlation being strongest for nuchal-fold thickness (r = 0.10). There was a higher frequency of cases with second-trimester nuchal-fold thickness above the 97.5th centile (10.7 vs. 2.2%) and hyperechogenic bowel (2.4 vs. 0.1%) in cases with increased NT. Conclusions Straightforward reassessment of risk using likelihood ratios derived from the second-trimester genetic sonogram might lead to inaccurate estimates. Multivariate models using continuous second-trimester variables might be preferable in sequential screening strategies. Copyright. 2012 ISUOG. Published by John Wiley & Sons, Ltd.

Multiple trichoblastomas in a dog

Background – Hair follicle tumours generally present as benign, solitary masses and have a good prognosis following surgical resection. Hypothesis/Objectives – This report describes a case of multiple trichoblastomas in a dog. Animal – A 2-year-old crossbred dog presented with multiple soft cutaneous periocular, perilabial, submandibular and nasal nodules, between 2 and 9 cm in diameter, located on the right side of the face. New nodules were observed on the same side of the face at a second consultation 3 weeks later. Methods – Surgical resection of all nodules was performed in two procedures. Three nodules were initially resected and submitted for histolopathology and immunohistochemistry. The diagnosis was trichoblastoma for all three. At the time of the second consultation, new and remaining nodules were biopsied and the diagnosis of trichoblastoma confirmed. The dog was treated with doxorubicin and piroxicam for 30 days prior to the second surgical procedure in an attempt to reduce new tumour growth and the size of present tumours. All nodules were resected and the defects closed using rotation flaps. Results – No recurrence of the neoplasm was noted within 10 months after surgery. Conclusions and clinical importance – Trichoblastomas are generally benign but can present as multiple neoplasms that may require surgical resection and may respond to chemotherapy. To the authors’ knowledge, this is the first report of multiple trichoblastomas in a dog.

Utilizzo di dispositivi magnetici nel trattamento della patologia artrosica del ginocchio

The use of scaffolds for Tissue Engineering (TE) is increasing due to their efficacy in helping the body rebuild damaged or diseased tissue. Hydroxyapatite (HA) is the most suitable bioactive ceramic to be used in orthopaedic reconstruction since it replicates the mineral component of the hard tissues, and it has therefore excellent biocompatibility properties. The temporal and spatial control of the tissue regeneration process is the limit to be overcome in order to treat large bone and osteochondral defects. In this thesis we describe the realization of a magnetic scaffolds able to attract and take up growth factors or other bio-agents in vivo via a driving magnetic force. This concept involves the use of magnetic nanoparticles (MNP) functionalized with selected growth factors or stem cells. These functionalized MNP act as shuttles transporting the bio-agents towards and inside the scaffold under the effect of the magnetic field, enhancing the control of tissue regeneration processes. This scaffold can be imagined as a fixed “station” that provides a unique possibility to adjust the scaffold activity to the specific needs of the healing tissue. Synthetic bone graft substitutes, made of collagen or biomineralized collagen (i.e. biomimetic Hydroxyapatite/collagen composites) were used as starting materials for the fabrication of magnetic scaffolds. These materials are routinely used clinically to replace damaged or diseased cartilaginous or bone tissue. Our magnetization technique is based on a dip-coating process consisting in the infilling of biologically inspired porous scaffolds with aqueous biocompatible ferrofluids’ suspensions. In this technique, the specific interconnected porosity of the scaffolds allows the ferrofluids to be drawn inside the structure by capillarity. A subsequent freeze-drying process allows the solvent elimination while keeping very nearly the original shape and porosity of the scaffolds. The remaining magnetic nanoparticles, which are trapped in the structure, lead to the magnetization of the HA/Collagen scaffold. We demonstrate here the possibility to magnetize commercially available scaffolds up to magnetization values that are used in drug delivery processes. The preliminary biocompatibility test showed that the investigated scaffolds provide a suitable micro-environment for cells. The biocompatibility of scaffold facilitates the growth and proliferation of osteogenic cells.

Diagnosi prenatale delle malformazioni fetali: ecografia e risonanza magnetica a confronto in 11 anni di esperienza

Obiettivo: Valutare l’accuratezza reciproca dell’ecografia “esperta” e della risonanza magnetica nelle diagnosi prenatale delle anomalie congenite. Materiali e metodi: Sono stati retrospettivamente valutati tutti i casi di malformazioni fetali sottoposte a ecografia “esperta” e risonanza magnetica nel nostro Policlinico da Ottobre 2001 a Ottobre 2012. L’età gestazionale media all’ecografia e alla risonanza magnetica sono state rispettivamente di 28 e 30 settimane. La diagnosi ecografica è stata confrontata con la risonanza e quindi con la diagnosi postnatale. Risultati: sono stati selezionati 383 casi, con diagnosi ecografica o sospetta malformazione fetale “complessa” o anamnesi ostetrica positiva infezioni prenatali, valutati con ecografia “esperta”, risonanza magnetica e completi di follow up. La popolazione di studio include: 196 anomalie del sistema nervoso centrale (51,2%), 73 difetti toracici (19,1%), 20 anomalie dell’area viso-collo (5,2%), 29 malformazioni del tratto gastrointestinale (7,6%), 37 difetti genito-urinari (9,7%) e 28 casi con altra indicazione (7,3%). Una concordanza tra ecografia, risonanza e diagnosi postnatale è stata osservata in 289 casi (75,5%) ed è stata maggiore per le anomalie del sistema nervoso centrale 156/196 casi (79,6%) rispetto ai difetti congeniti degli altri distretti anatomici 133/187 (71,1%). La risonanza ha aggiunto importanti informazioni diagnostiche in 42 casi (11%): 21 anomalie del sistema nervoso centrale, 2 difetti dell’area viso collo, 7 malformazioni toraciche, 6 anomalie del tratto gastrointestinale, 5 dell’apparato genitourinario e 1 caso di sospetta emivertebra lombare. L’ecografia è stata più accurata della risonanza in 15 casi (3,9%). In 37 casi (9,7%) entrambe le tecniche hanno dato esito diverso rispetto agli accertamenti postnatali. Conclusioni: l’ecografia prenatale rimane a tutt’oggi la principale metodica di imaging fetale. In alcuni casi complessi e/o dubbi sia del sistema nervoso centrale sia degli altri distretti anatomici la risonanza può aggiungere informazioni rilevanti.

Funktionelle Charakterisierung der Protein-Kinase CK2 in der Suppression Th2-vermittelter Immunantworten durch regulatorische T-Zellen

Regulatorische T-Zellen (Tregs) leisten durch ihre suppressiven Eigenschaften einen essenziellen Beitrag zur Aufrechterhaltung der immunologischen Toleranz. Sie verhindern schädliche Immunreaktionen gegen Autoantigene, kommensale Bakterien, sowie harmlose Nahrungsmittel-bestandteile. Gleichzeitig gewährleisten sie die Entwicklung effektiver Immunantworten gegen eindringende Pathogene, wie z.B. Parasiten, Bakterien und Viren. Damit haben Tregs direkten Einfluss auf das Gleichgewicht zwischen Immunität und Toleranz. Fehler in der suppressiven Funktionsweise von Tregs begünstigen daher auf der einen Seite die Entstehung zahlreicher autoimmuner Erkrankungen und Allergien. Auf der anderen Seite können Tregs Immunreaktionen bei chronischen Infektionen reduzieren, sowie die Entstehung effektiver Immunantworten gegen Tumore hemmen. Ihre Beteiligung an der Ätiologie all dieser Krankheiten macht Tregs zu einem bedeutenden potenziellen Zielobjekt, um diese Krankheiten effektiv zu therapieren. Die Erweiterung des Grundwissens um die molekularen Mechanismen der Treg-vermittelten Suppression ist daher ein notwendiger Schritt bei der Entwicklung Treg-basierter Theraphieansätze. 2003 konnte mit Foxp3 ein Transkriptionsfaktor identifiziert werden, der maßgeblich die suppressiven Funktionen von Tregs steuert. Um weiteren Einblick in die der Suppression zugrundeliegenden Signalwege zu erhalten, wurde im Institut für Immunologie ein komparativer Kinomarray durchgeführt, anhand dessen die Casein Kinase 2 (CK2) als eine der aktivsten Kinasen in Tregs identifiziert wurde (Daten freundlicherweise von Prof. Dr. Tobias Bopp bereitgestellt). rnBasierend auf den Ergebnissen des Kinomarrays wurde in dieser Arbeit die Funktion der CK2 in Tregs untersucht. Dabei konnte in in vitro Experimenten die Treg-vermittelte Suppression durch den pharmakologische CK2 Inhibitor DMAT aufgehoben werden. Weil derartige Inhibitoren jedoch nicht absolut spezifisch die Aktivität nur einer Kinase supprimieren, wurden außerdem Mäuse mit konditionalem „knockout“ der CK2β Untereinheit spezifisch in Tregs gekreuzt (CK2βTreg-/- Mäuse). Die Analyse dieser Tiere offenbarte eine essenzielle Beteiligung der CK2 an den suppressiven Funktionen von Tregs. So entwickeln CK2βTreg-/- Mäuse mit zunehmendem Alter Splenomegalien und Lymphadenopathien, von denen in besonderem Maße die Mukosa-assoziierten Lymphknoten betroffen sind. Eine Analyse des Aktivierungsstatus der T-Zellen in den Tieren konnte zudem einen erhöhten Anteil sogenannter Effektor-Gedächtnis T-Zellen aufdecken, die charakteristische Merkmale eines Th2 Phänotyps zeigten. Erhöhte Titer des Antikörperisotyps IgE in den Seren von CK2βTreg-/- Mäusen suggerieren zusätzlich eine fehlerhafte Suppression speziell Th2-vermittelter Immunantworten durch CK2β-defiziente Tregs. In Th2-vermittelten Asthma Experimenten in vivo konnte der Verdacht der fehlerhaften Kontrolle von Th2-Antwort bestätigt werden, wobei zusätzlich aufgedeckt wurde, dass bereits unbehandelte CK2βTreg-/- Mäuse Zeichen einer Entzündungsreaktion in der Lunge aufweisen. Bei der Suche nach den molekularen Ursachen der fehlerhaften Suppression Th2-vermittelter Immunantworten durch CK2β-defiziente Tregs konnten zwei mögliche Erklärungsansätze gefunden werden. Zum einen zeigen CK2β-defiziente Tregs eine verringerte Expression von Foxp3, was, in Analogie zu Ergebnissen der Gruppe von R. Flavell (Wang Y.Y. Nature. 445, 766-770 (2007)), zu einer Konversion von Tregs zu Th2 Zellen und damit zur Entstehung eines Th2-basierten, autoimmunen Phänotyps führt. Des Weiteren weisen CK2β-defiziente Tregs eine reduzierte Expression des Transkriptionsfaktors IRF4 auf, der in Tregs entscheidend für die Kontrolle Th2-basierter Immunreaktionen ist (Zheng Y. Nature. 19; 351-356 (2009)). Die dargelegten Ergebnisse identifizieren die CK2 damit als Kinase, die entscheidend an der Treg-vermittelten Suppression speziell Th2-basierter Immunantworten beteiligt ist. Demnach könnten pharmakologische CK2 Inhibitoren beispielsweise dazu eingesetzt werden, um die Treg-vermittelte Suppression im Rahmen chronischer Parasiten-Infektionen aufzuheben. Die in CK2βTreg-/- Mäusen beobachtete Prävalenz der Funktion der CK2 für Mukosa-assoziierte Organe stellt dabei einen zusätzlichen Vorteil dar, weil systemische Nebenwirkungen, die durch die Blockade der Treg-vermittelte Suppression entstehen, zumindest in nicht-Mukosa-assoziierten Geweben nicht zu erwarten sind.rn

Palestinian Refugee Camps: from Shelter to Habitat

Palestinian refugees registered with UNRWA and their housing conditions are officially characterized by a “ temporary status” , a situation which has lasted the past sixty years. This article explores this time-paradox by focusing on the host governments’ and UNRWA’s policies affecting the refugees’ housing conditions. After having reviewed available literature, this contribution analyses the current housing situation. Drawing on data from a recent survey, the authors provide insights on areas where intervention is needed. In all UNRWA’s fields of operation, overcrowding, lack of public spaces, humidity and structural defects are the main sources of housing discomfort that camp refugees endure. Host countries’ restrictions as well as the incapacity or unwillingness of larger urban municipalities to incorporate refugee camps in their master plans are among the main obstacles to the refugees’ housing development. Rehabilitation and self-help re-housing programs may offer substantial incentives for housing improvement. The success of such programs depends, among several factors, on the host governments’ good will to provide UNRWA with authorizations, financial support, and land, as well as on the capacity of involving the refugee communities in projects’ planning and implementation.

Temperature-Dependent Defect Dynamics in the Network Glass SiO2

We investigate the long time dynamics of a strong glass former, SiO2, below the glass transition temperature by averaging single-particle trajectories over time windows which comprise roughly 100 particle oscillations. The structure on this coarse-grained time scale is very well defined in terms of coordination numbers, allowing us to identify ill-coordinated atoms, which are called defects in the following. The most numerous defects are O-O neighbors, whose lifetimes are comparable to the equilibration time at low temperature. On the other hand, SiO and OSi defects are very rare and short lived. The lifetime of defects is found to be strongly temperature dependent, consistent with activated processes. Single-particle jumps give rise to local structural rearrangements. We show that in SiO2 these structural rearrangements are coupled to the creation or annihilation of defects, giving rise to very strong correlations of jumping atoms and defects.

Is dental erosion really a problem?

Dental erosion is the non-carious dental substance loss induced by direct impact of exogenous or endogenous acids. It results in a loss of dental hard tissue, which can be serious in some groups, such as those with eating disorders, in patients with gastroesophageal reflux disease, and also in persons consuming high amounts of acidic drinks and foodstuffs. For these persons, erosion can impair their well-being, due to changes in appearance and/or loss of function of the teeth, e.g., the occurrence of hypersensitivity of teeth if the dentin is exposed. If erosion reaches an advanced stage, time- and money-consuming therapies may be necessary. The therapy, in turn, poses a challenge for the dentist, particularly if the defects are diagnosed at an advanced stage. While initial and moderate defects can mostly be treated non- or minimally invasively, severe defects often require complex therapeutic strategies, which often entail extensive loss of dental hard tissue due to preparatory measures. A major goal should therefore be to diagnose dental erosion at an early stage, to avoid functional and esthetic impairments as well as pain sensations and to ensure longevity of the dentition.

Versatility of the abductor hallucis muscle as a conjoined or distally-based flap

Soft tissue coverage of the medial ankle and foot remains a difficult, challenging, and often frustrating problem to patients as well as surgeons. To our knowledge, the abductor hallucis muscle flap is not frequently used and only a few well documented cases were found in literature. The purpose of this paper is to report and to present the long-term results of a series of four patients who underwent reconstruction of foot and ankle defects with the abductor hallucis muscle flap.In two cases, the abductor hallucis muscle flap was transposed in combination with a medialis pedis flap to cover a medial ankle defect, whereas in another case it was combined with a medial plantar flap. In this latter case, the muscle flap served to fill up a calcaneal dead space after osteomyelitis debridement, whereas the cutaneous flap was used to replace debrided skin at the heel. The abductor hallucis flap was used as a distally-based turnover flap to cover a large forefoot defect in a fourth case. Follow-up period ranged between 18 and 64 months (mean 43.3). In the early postoperative period, two flaps healed completely In two patients marginal flap necrosis occurred which was subsequently skin grafted. No donor-site complication occurred in any of the patients. In all cases, protective sensation of the skin was satisfactory as early as 6 months. In two cases mild hyperkeratosis at the skin graft border to the sole skin (non-weight bearing area of medial plantar and medialis pedis flap donor site) was present, but probably related to poor foot care. All patients were fully mobile as early as 3 months after treatment. In the long-term follow-up (43.3 months), all flaps provided with durable coverage. Functional gait deficit due to consumtion of the abductor hallucis muscle was not apparent.Our long-term results demonstrated that the abductor hallucis muscle flap is a versatile, and reliable flap suitable for the reconstruction of foot and ankle defects. Utilizing the abductor hallucis muscle as a pedicled flap (distally or proximally-based) with or without conjoined regional fasciocutaneous flaps offers a successful and durable alternative to microsurgical tree flaps for small to moderate defects over the calcaneus region, medial ankle, medial foot, and forefoot with exposed bone, tendon, or joint.

[Cosmetic results after breast conserving carcinoma treatment in patients with intramammarian seromas]

INTRODUCTION: There were 373 patients irradiated after breast conserving carcinoma treatment. A planning computed tomography revealed in 97 of these patients seromas and tissue defects exceeding 2cm in diameter. The cosmetic results in those patients and the impact of seromas herein had to be evaluated. PATIENTS AND METHODS: Mean age was 59 years. A quadrant resection was performed in 17.5 percent of the patients, a segmental resection in 27.8 percent and a tumour excision in 54.6 percent. Radiation therapy was applied with the Linear accelerator and 6 MeV photons up to a total dose in the residual breast of 50 Gy followed by a boost dose to the former tumour bed of 10 Gy. A distinct evaluation and documentation of therapy related side effects and the resulting cosmesis was done in 51 patients. RESULTS: In all the examined seroma patients there were moderate acute skin reactions grade 1 to 3. As late effects in 82.3 percent scar indurations were noticed. At the skin 51 percent showed enhanced pigmentation, 68.6 percent atrophia and only 11 percent teleangiectasia. Subcutaneous fibrosis occurred in 56,9 percent of the patients, 78.4 percent of the women had breast asymmetries. In 41.2 percent there were a lymphedema subcutaneously, in 72.5 percent impaired sensibility. The overall cosmetic result documented with a 5 point score was "very good" (score 1) in 19.6 percent and "good" (score 2) in 33.3 percent, 37.3 percent were "satisfactory" (score 3) and 9.8 percent "bad" (score 4) respectively. No "very bad" results (score 5) were seen. CONCLUSIONS: The cosmetic results in the examined group of seroma and hematoma patients were inferior to those reported in the literature. We conclude that postoperative seroma and hematoma have an adverse effect on the resulting cosmesis and that their frequency and extent have to be reduced in future by the responsible surgeons.
