The occurrence and pathogenicity of Serratospiculum tendo (Nematoda: Diplotriaenoidea) in birds of prey from southern Italy.

The air sacs of free-ranging birds of prey (n= 652) from southern Italy, including 11 species of Accipitriformes and six of Falconiforms, were examined for infections with Serratospiculum tendo (Nematoda: Diplotriaenoidea). Of the 17 species of birds examined, 25 of 31 (80.6%) peregrine falcons (Falco peregrinus) from Calabria Region and a single northern goshawk (Accipiter gentilis) from Campania Region were infected with S. tendo, suggesting a strong host specificity for the peregrine falcon. The northern goshawk and 18 of 25 infected peregrine falcons showed cachexia and all infected birds had bone fractures. At gross examination, air sacculitis and pneumonia were the most common lesions in infected birds. Microscopically, the air-sac walls showed thickening of the smooth muscle cells, resulting in a papillary appearance, along with hyperplasia of the mesothelium and epithelium, and foci of plasma cell infiltration and macrophages associated with several embryonated eggs and adult parasites. Extensive areas of inflammation were found in the lungs, characterized by lymphocytes, macrophages and fibroblasts surrounding embryonated eggs. The northern goshawk also had detachment of the dextral lung with several necrotic foci. In this case, the death of the bird was directly attributed to S. tendo infection. Lesions and pathological changes observed here suggest that S. tendo can cause disease.

Progesterone and its derivatives for the treatment of catamenial epilepsy: A systematic review.

OBJECTIVE: Catamenial epilepsy (CE) is defined as an increase in seizure frequency during specific phases of the menstrual cycle in women with epilepsy. The treatment usually includes a combination of non-hormonal and hormonal therapies. This systematic review summarizes the available data on the efficacy of progesterone and its derivates to treat CE. METHODS: We performed a systematic search of the literature to identify studies reporting data on the use of progesterone and its derivatives (any type and dose) for the treatment of CE. The main outcome included the efficacy of progesterone and its derivatives on seizure frequency. RESULTS: Nineteen articles (457 patients) were included; four were randomized controlled trials (two comparing progesterone vs placebo and two comparing norethisterone vs placebo). Progesterone was generally administered during the luteal phase (from day 15 to 25) or during perimenstrual exacerbations (from day 23 to 25), with an average dose of 10-30 mg/day to a maximum of 300 mg/day. The therapy, usually well tolerated, was ineffective in the randomized controlled trials; conversely, it was associated with an overall reduction in seizure frequency in case reports and uncontrolled studies. CONCLUSIONS: Although data from uncontrolled studies suggest that hormone therapy with progesterone may be useful in the treatment of CE, its efficacy has not been demonstrated in controlled trials. The possible antiseizure effect of progesterone could be mediated by its active metabolite allopregnanolone, making the plasmatic measurement of these hormones mandatory to evaluate efficacy. Further randomized controlled trials should investigate the efficacy of progesterone and its derivatives, addressing these pharmacological issues.

A setup for element specific magnetization dynamics using the transverse magneto-optic Kerr effect in the energy range of 30-72 eV.

In this paper, we present a spectrometer that is designed for element-specific and time-resolved transverse magneto-optic Kerr effect experiments at the high-harmonic generation pump-probe facility High Energy Laser Induced Overtone Source (HELIOS) laboratory. HELIOS delivers photons with energies between 30 eV and 72 eV with an overall time resolution of less than 40 fs. The spectrometer is based on a Rowland-circle geometry and allows for simultaneous measurements of all magnetic transition-metal elements. The setup also features easy sample transfer and alignment, and it combines high photon throughput, optimized data acquisition, and a fast switching of the magnetic field at the sample. The spectrometer performance is demonstrated by measuring the ultrafast demagnetization of permalloy. Our data are, for all practical purposes, identical to what have been reported in the earlier high-order harmonic generation work of a similar sample by Mathias et al. [Proc. Natl. Acad. Sci. U. S. A. 109, 4792-4797 (2012)], however, obtained within 15% of the acquisition time compared to their study. Furthermore, our data show a shift of the demagnetization curve of Ni relative to Fe, which has previously been interpreted as a delay of the Ni demagnetization to that of Fe [S. Mathias et al., Proc. Natl. Acad. Sci. U. S. A. 109, 4792-4797 (2012)].

Mandibular metastatic hepatocellular carcinoma: report of a case involving severe and uncontrollable hemorrhage.

Hepatocellular carcinoma (HCC) is a malignant tumor with a marked tendency to spread through the portal system. Metastases from HCC usually involve lungs, surrenal glands, the skeletal and gastroenteric systems, spleen, heart and kidneys. Secondary localizations to the mandible are rare. Generally, bone metastases from HCC appear as osteolytic lesions more likely localized to the ribs, spine, femor, omer, sternum, and then to the mandible. Mandibular metastatic HCC is hemorrhagic in nature because of its hypervascularity. Any diagnostic maneuver that could end in bleeding should be avoided. Non-invasive diagnostic procedures such as computer tomography (CT) scan should be preferred. Among the invasive diagnostic procedures, only fine needle biopsy should be attempted and palliative radiotherapy could be useful for the control of local symptoms. A case report of a hemorrhagic mandibular metastatic HCC that had to be treated surgically, in order to control the severe and profuse bleeding, is presented.

[Diagnosis and logopedic rehabilitation in mandibulofacial dysostosis: a case report]. / Diagnosi e riabilitazione logopedica della disostosi mandibolo-facciale: un caso clinico.

TCS is hereditary condition transmitted as an autosomal dominant with a high penetrance rate and variable expressivity. Over half the cases derives from new mutations. A pathological gene has been located on the chromosome 5, between locus 31 and 34 of the long arm. The clinical picture is dominated by mandible-facial impairment and by numerous associated deficits, among which a hearing deficit. Therapy requires plurispecialistic intervention, personalized according to each patients condition. The Authors report the case of a three-year-old girl with transmissive deafness and serious language retardation. The child successfully underwent logopedical therapy for three years. The Authors conclude affirming that very young patients with S. Treacher Collins-Franceschetti have a very good chance of being inserted into society furthermore improved by the absence lack of mental deficiency and by spontaneous improvement in physical appearance.

[Endoscopic treatment of orbital cellulitis in pediatric patients: transethmoidal approach]. / Tratamiento endoscópico de la celulitis orbital en la infancia: abordaje transetmoidal.

Orbital cellulitis is a septic process of the soft tissues behind the orbital septum and is the most frequent cause of the monolateral exophthalmos in pediatrics. Approximately 90% of the orbital cellulitis in pediatrics are associated to acute ethmoiditis. From the 01.01.2001 to 31.12.2010 we treated 36 patients, less than 18 years-old affected by Chandler stage II, III, or IV orbital cellulitis. The inflammation was resolved medically in 6 patients. In the 30 cases that showed no improvement in 48-72 h, an endoscopic drainage of the pus was performed by the transethmoidal route. In children, an adenoidectomy should be included, in order to eliminate eventual infections of this lymphatic organ. Endoscopic treatment has resulted in rapid resolution of disease without any complications. In addition, postoperative discomfort is minimal, with a rapid return to daily activities.

Postsurgical dyskeratosis treated with topical and parenteral administration of vitamin A.

A severe case of conjunctival dyskeratosis was resolved by treatment with high doses of vitamin A administered both topically and parenterally. This result, which was confirmed by cytology, and the lack of adverse effects suggest that vitamin A administration might be a valid alternative to surgery in cases of dyskeratosis.

Tratamiento endoscópico de la celulitis orbital en la infancia: abordaje transetmoidal / Endoscopic treatment of orbital cellulitis in pediatric patients: Transethmoidal approach

La celulitis periorbitaria es un proceso séptico de los tejidos blandos orbitarios y representa la causa más frecuente de exoftalmos unilateral en la infancia. Aproximadamente el 90% de los casos de celulitis periorbitaria en edad pediátrica se asocian a etmoiditis aguda. En el periodo 1.° de enero de 2001–31 de diciembre de 2010 se han tratado 36 pacientes menores de 18 años con celulitis periorbitaria en los estadios II, III, IV de Chandler. Seis pacientes consiguieron la resolución de la inflamación con el tratamiento farmacológico. En 30 casos que no demostraron una mejoría en un período de 48 a 72 h, se efectuó un drenaje quirúrgico endoscópico del moco-pus con abordaje por vía transetmoidal. En los niños es muy importante no olvidar el tratamiento quirúrgico de la adenoiditis crónica que, con toda probabilidad, se presentará simultáneamente. La cirugía endoscópica permite una rápida resolución de la enfermedad sin ninguna complicación. Además, el malestar postoperatorio es mínimo, permitiendo un rápido regreso a las actividades cotidianas (AU)
