Tuberculous Otitis Media with Facial Paralysis: A Clinical and Microbiological Diagnosis—A Case Report
Nicola Quaranta,Paolo Petrone,Alexandra Michailidou,Luisa Miragliotta,Marilina Santantonio,Raffaele Del Prete,Adriana Mosca,Giuseppe Miragliotta
Case Reports in Infectious Diseases , 2011, DOI: 10.1155/2011/932608
Abstract: The tuberculosis of the ear is rare, and in most cases the clinical picture resembles that of a chronic otitis media. The diagnosis is often delayed, and this can lead to irreversible complications such as hearing loss and/or facial paralysis. In view of its rare occurrence, we report a case of primary tuberculous otitis media in a 87-year-old female patient. The diagnosis was made on the basis of both histological and microbiological findings. In particular, gene amplification techniques such as real-time polymerase chain reaction are useful method for rapid diagnosis and detecting tuberculous bacilli usually present at very low number. Early diagnosis is essential for the prompt institution of antituberculous therapy.

Abstract: A matched case control study was conducted, on 19 July 2005, for investigating risk factors, using a structured questionnaire on food consumption. A multivariate analysis was conducted to estimate the adjusted Odds Ratios. Laboratory and environmental investigation were also performed.On the day of the study 41 cases were identified and 41 controls were enrolled. Controls were matched for age and gender. The mean age of the cases was 26 years old, and 58% were female. The clinical pattern of the disease was characterised by the presence of diarrhoea (95%), vomiting (70%), abdominal pain (51%) and fever (32%). Of the 41 cases included in the study, the majority (65%) were residents of Northern Italian regions. No food samples were available for testing. The matched univariate analysis revealed that cases were more likely to have consumed raw mussels, eggs or ice cubes made of tap water than controls. In the multivariate conditional logistic regression analysis, having eaten raw mussels or ice became more strongly associated with illness.All of the 20 faecal samples collected were tested for NoVs. Eighteen stools (90% of total examined) were positive by RT-PCR, and sequence analysis performed onto 3 samples confirmed the presence of a GGII NoV. No test specific for NoV was performed on water or food samples.The most likely hypothesis supported by the findings of the epidemiological investigation was that illness was associated with raw mussels and ice, made with tap water. These hypothesis could not be confirmed by specific microbiologic testing for NoV in food or ice. The lack of clear knowledge of NoV as a major causative agent of epidemic outbreaks of gastroenteritis in Italy is due to the absence of timely reporting of the cases to the local public health offices and the uncommon practice of saving clinical samples for virological analysis after bacteriological testing.Norovirus (NoV) constitutes one of the four genera of the Caliciviridae family [1].

Weak type (1, 1) of maximal operators on metric measure spaces
Carena,Marilina;
Revista de la Uni?3n Matem??tica Argentina , 2009,
Abstract: a discretization method for the study of the weak type (1, 1) for the maximal of a sequence of convolution operators on has been introduced by miguel de guzmán and teresa carrillo, by replacing the integrable functions by finite sums of dirac deltas. trying to extend the above mentioned result to integral operators defined on metric measure spaces, a general setting containing at once continuous, discrete and mixed contexts, a caveat comes from the result in on restricted weak type (1, 1); the discrete case (akcoglu m.; baxter j.; bellow a.; jones r., israel j. math. 124 (2001), 285-297). there a sequence of convolution operators in is constructed such that the maximal operator is of restricted weak type (1, 1), or equivalently of weak type (1, 1) over finite sums of dirac deltas, but not of weak type (1, 1). the purpose of this note is twofold. first we prove that, in a general metric measure space with a measure that is absolutely continuous with respect to some doubling measure, the weak type (1, 1) of the maximal operator associated to a given sequence of integral operators is equivalent to the weak type (1, 1) over linear combinations of dirac deltas with positive integer coefficients. second, for the non-atomic case we obtain as a corollary that any of these weak type properties is equivalent to the weak type (1, 1) over finite sums of dirac deltas supported at different points.
On s-sets in spaces of homogeneous type
Marilina Carena,Marisa Toschi
Mathematics , 2013,
Abstract: Let $(X,d,\mu)$ be a space of homogeneous type. In this note we study the relationship between two types of $s$-sets: relative to a distance and relative to a measure. We find a condition on a closed subset $F$ of $X$ under which we have that $F$ is $s$-set relative to the measure $\mu$ if and only if $F$ is $s$-set relative to $\delta$. Here $\delta$ denotes the quasi-distance defined by Mac\'ias and Segovia such that $(X,\delta,\mu)$ is a normal space. In order to prove this result, we show a covering type lemma and a type of Hausdorff measure based criteria for the $s$-set condition relative to $\mu$ of a given set.
Organic Residues Analysis: The Case of a Beaker Found in Theban Necropolis, Egypt
Federica FACCHETTI,Erika RIBECHINI,Marilina BETRò,Maria Perla COLOMBINI
International Journal of Conservation Science , 2012,
Abstract: Amorphous organic residues collected from a ceramic vessel from a tomb excavated in the Theban Necropolis (Egypt) were chemically investigated by an analytical procedure based on gas chromatography coupled with mass spectrometry (GC/MS). Little is known about Egyptian ceramic vessels, thus retrieving valuable information on the use of ceramics from the chemical analyses of organic residues was a key aspect of this work. The results showed that the vessel was used in connection with a number of substances such as beeswax, fat/oil and Pinaceae resin. This enabled us to draw hypotheses on the possible function of artefact in connection with mummification practices.

Powers of distances to lower dimensional sets as Muckenhoupt weights
Hugo Aimar,Marilina Carena,Ricardo Durán,Marisa Toschi
Mathematics , 2013,
Abstract: Let $(X,d,\mu)$ be an Ahlfors metric measure space. We give sufficient conditions on a closed set $F\subseteq X$ and on a real number $\beta$ in such a way that $d(x,F)^\beta$ becomes a Muckenhoupt weight. We give also some illustrations to regularity of solutions of partial differential equations and regarding some classical fractals.
Eficácia da aromaterapia na redu??o de níveis de estresse e ansiedade em alunos de gradua??o da área da saúde: estudo preliminar

Abstract: the purpose of this study was to assess the efficacy of aromatherapy in decreasing stress and anxiety levels in undergraduate health science students. thirty-six students aged 18 to 29 were divided into those who received treatment (aroma group, n=18) and a control group (n=18). all subjects were assessed as to stress and anxiety levels before and after the treatment, by means of the list of stress symptoms and the state-trait anxiety inventory. the aromatherapy treatment consisted in twice weekly, 10-minute inhalations of a synergy of essential oils made specifically for this study, for a total of 7 sessions. stress and anxiety scores measured before and after treatment were statistically compared, with significance level set at 5% (p<0.05). the aroma group showed a significant (p<0,05) decrease in stress (less 24%) and anxitey (less 13% and 19%) levels, while in control group only a significant, though lesser (11%) stress level decrease could be noticed. aromatherapy thus proved effective in reducing stress and anxiety levels in graduate health students, but there is still great need to further studies to identify causes of the levels assessed, as well as the mechanisms whereby essential oils might have reduced them.

Abstract: Fourteen healthy mares were used in this study. Estruses were synchronized and seven mares were treated with intrauterine infusions at days 0 and 2 post ovulation of two consecutive estrous cycles. Uterine biopsy samples were taken on days 6 and 15 post ovulation.The treatment did not induce an inflammatory response indicating endometritis, neither affected the ERα. However, it reduced the percentage of PR positive cells (PPC) on day 6 (deep glandular epithelium, control: 95.7 vs. infused: 61.5, P < 0.05). Treated mares tended to have lower progesterone levels on day 2 (3.9 ng/ml vs. 6.6 ng/ml, P = 0.07), and higher levels on day 15 compared with controls (4.4 ng/ml vs. 1.3 ng/ml, P = 0.07).a 1% povidone-iodine infusion during days 0 and 2 post ovulation in healthy mares did not induce histological changes indicating endometritis, but altered progesterone concentrations and reduced the expression of endometrial PR at day 6 without affecting the ERα. These changes could reduce embryo survival.Endometritis is a major cause of infertility in the mare [1] and factors such as perineal conformation and uterine clearance that depend on the breed, age and reproductive status contribute to the pathogenesis [2]. Rapid physical clearance of uterine contents after mating or foaling is most important in the uterine defence [2]. Therefore, intrauterine infusions have been used widely in the equine practice as a treatment to clear the uterus within 96 hours post ovulation [2-4]. The objective is that the embryo encounters a healthy endometrium around day 6, when it enters the uterus [5]. Povidone-iodine solutions are often used for intrauterine infusions due to their low cost, easy of preparation, storage and delivery and especially because they are indicated for the treatment of fungal infections [2,4]. However, contradictory findings have been reported on the consequences of using this antiseptic. A 0.05% povidone iodine solution infused into the uterus around the time of ovulat

Abstract: The ex vivo celiac ganglion-superior ovarian nerve-ovary integrated system was used. This model allows studying in vitro how direct neural connections from the celiac ganglion regulate ovarian steroidogenic output. The system was incubated in buffer solution with the ganglion and the ovary located in different compartments and linked by the superior ovarian nerve. Three experiments were designed with the addition of: 1) noradrenaline in the ganglion compartment; 2) LH in the ovarian compartment; and 3) noradrenaline and LH in the ganglion and ovarian compartments, respectively. Rats of 15, 19, 20 and 21 days of pregnancy were used, and, as an end point, the concentration of the luteotropic hormone androstenedione was measured in the ovarian compartment by RIA at various times of incubation. For some of the experimental paradigms the concentration of various catecholamines (dihydroxyphenylalanine, dopamine, noradrenaline and adrenaline) was also measured in the ovarian compartment by HPLC.The most relevant result concerning the action of noradrenaline in the celiac ganglion was found on day 21 of pregnancy resulting in the inhibition of androstenedione release from the ovarian compartment. In addition on day 15 of pregnancy, LH placed in the ovarian compartment led to an inhibition of the release of androstenedione, and this inhibitory effect was further reinforced by the joint action of noradrenaline in the celiac ganglion and LH in the ovary. The levels of catecholamines in the ovarian compartment showed differences among the experiments; of significance, the joint treatment of noradrenaline in the celiac ganglion and LH in the ovary resulted in a remarkable increase in the ovarian levels of noradrenaline and adrenaline when compared to the effect achieved by either one of the compounds added alone.Our results demonstrate that the noradrenergic stimulation of the celiac ganglion reinforces the LH-induced inhibition of androstenedione production by the ovary of late
