Salve Medical College, Nagpur, Maharashtra, 4Department of Medicine, Mahatma Gandhi Medical College and Research Institute, Jaipur, Rajasthan, India Introduction: von Voss-Cherstvoy syndrome is a part of a group of syndromes with radial and hematologic abnormalities, and until now approximately ten cases have been reported in the literature. This syndrome is characterized by a triad of radial ray defects, occipital encephalocele, and urogenital abnormalities.Case presentation: We report a neonate from Indian ethnicity who was diagnosed with von Voss-Cherstvoy syndrome. The neonate had radial ray defect, occipital encephalocele, tetralogy of Fallot, and bilateral agenesis of kidney, ureter, and bladder. The neonate was suspected to have von Voss-Cherstvoy syndrome on the basis of clinical features, which was further confirmed by fibroblast analysis showing somatic mosaicism for del(13q).Conclusion: von Voss-Cherstvoy syndrome is a very rare syndrome that can be suspected on the basis of typical clinical features and confirmed by fibroblast analysis showing somatic mosaicism for del(13q). This adds a second case of this chromosome anomaly described in this syndrome. Keywords: von Voss-Cherstvoy syndrome, radial ray defects, occipital encephalocele, urogenital abnormalities, somatic mosaicism for del(13q)

Deepak Sharma,1 Ravinder Singh,2 Sweta Shastri3 1Department of Neonatology, Fernandez Hospital, Hyderabad, 2Department of Pediatrics, Civil Hospital, Hisar, Haryana, 3Department of Pathology, NKP Salve Medical College, Nagpur, Maharashtra, India Abstract: Aphallia (absence of penis) is an extremely rare abnormality which has rarely been described in medical literature and can be part of the urorectal septum malformation sequence (URSMS). URSMS has hardly been reported in medical literature and includes the absence of perineal and anal openings in association with ambiguous genitalia and urogenital, colonic, and lumbosacral anomalies. This case report tells the importance of detailed examination of infants that are diagnosed with aphallia. We report a case of a newborn who was diagnosed as aphallia with the URSMS syndrome after birth. The neonate had an endocardial cushion defect (atrial septal defect and ventricular septal defect) and bilateral agenesis of the kidney. The neonate succumbed to death secondary to hypoplastic lung leading to respiratory failure.

CB is not a specific disease entity, but is a common phenotype in conditions like harlequin ichthyosis, lamellar ichthyosis, nonbullous congenital ichthyosiform erythroderma, and trichothiodystrophy. We report a CB that was brought to our department and later diagnosed to have TGM1 gene c.984+1G>A mutation. However, it could not be ascertained whether the infant had lamellar ichthyosis or congenital ichthyosiform erythroderma (both having the same mutation). The infant was lost to follow-up.Keywords: cellophane membrane, c.984+1G>A mutation, lamellar ichthyosis, nonbullous congenital ichthyosiform erythroderma, parchment membrane, TGM1 gene

India is a high-risk country for cervical cancer which accounts a quarter (126 000 new cases, 71 000 deaths around 2 000) of the world burden. The age-standardized incidence rates range from 16-55 per 100 000 women in different regions with particularly high rates in rural areas. Control of cervical cancer by early detection and treatment is a priority of the National Cancer Control Programme of India. There are no organized cytology screening programmes in the country. The technical and financial constraints to organize cytology screening have encouraged the evaluation of visual inspection approaches as potential alternatives to cervical cytology in India. Four types of visual detection approaches for cervical neoplasia are investigated in India: a) naked eye inspection without acetic acid application, widely known as 'downstaging'; b) naked eye inspection after application of 3-5% acetic acid (VIA); c) VIA using magnification devices (VIAM); d) visual inspection after the application of Lugol's iodine (VILI). Downstaging has been shown to be poorly sensitive and specific to detect cervical neoplasia and is no longer considered as a suitable screening test for cervical cancer. VIA, VIAM and VILI are currently being investigated in multicentre cross-sectional studies (without verification bias), in which cytology and HPV testing are also simultaneously evaluated, and the results of these investigations will be available in 2003. These studies will provide valuable information on the average, comparative test performances in detecting high-grade cervical cancer precursors and cancer. Results from pooled analysis of data from two completed studies indicated an approximate sensitivity of 93.4% and specificity of 85.1% for VIA to detect CIN 2 or worse lesions; the corresponding figures for cytology were 72.1% and 91.6%. The efficacy of VIA in reducing incidence of and mortality from cervical cancer and its cost-effectiveness is currently being investigated in two cluster randomized controlled intervention trials in India. One of these studies is a 4-arm trial addressing the comparative efficacy of VIA, cytology and primary screening with HPV DNA testing. This trial will provide valuable information on comparative detection rates of CIN 2-3 lesions by the middle of 2003. The expected outcomes from the Indian studies will contribute valuable information for guiding the development of public health policies on cervical cancer prevention in countries with different levels of socio-economic and health services development and open up new avenues of research.

In this paper, a compact size, high gain, narrow beam array antenna is proposed for RFID application. A suitable compact size antenna with a gain of 7 dBi is designed as basic element for the array. This base antenna is designed using three slots. Unlike other works, all the three slots are different in shape. Electrical equivalent for this antenna is also proposed to understand antenna working. The same compact antenna is used as basic element to design a 2 x 2 antenna array. A 4:1 feeding network is designed and electrical equivalent of the same is proposed to show power division among the four-radiating patches. Overall size of antenna array is 1.04 λ0 x 1.04 λ0 x 0.029 λ0 mm3. Array's radiation beamwidth is 530 and gain of the antenna array is 10.3 dBi. All the measured results are in good agreement with simulated results. The proposed work is compared with other existing works and is found to be highly compact with excellent gain for the same size.

This paper presents novel approaches used to achieve compactness of printed circular antenna and circular polarization. Size reduction is achieved using three different shapes of slots unlike the conventional technique which uses similar slots. Overall dimension of the antenna is 0.52 λo x 0.52 λo x 0.029 λo mm3 and achieved by combining two circular sector slots of length 900, circular slot of radius 25 mm and a diametric slit of length 15 mm to the patch. Finally, circular slot is replaced by elliptical one to achieve circular polarization. Electrical equivalent of antenna is discussed at each design stage. The antenna is designed to cover UHF RFID application band and bandwidth obtained is 41 MHz with antenna gain of 7.3 dBi at 866 MHz. The proposed work is compared with other existing work and is observed that the proposed antenna not only is compact in size but has higher gain. All the measured results are in close agreement with the simulated results and proposed antenna is a very suitable candidate for making high gain compact array antenna. [ABSTRACT FROM AUTHOR]

The influences of GaI3, InI, and T1I on the evaporation characteristics of CeI3 have been studied over the temperature range 900K to 1400K using x-ray induced fluorescence. The total vapor densities, summed over all atomic and molecular species, of Ce, I, In, and T1 were obtained. Measurements of Ce were limited to temperatures above 1033K, the melting temperature of CeI3. This is the highest temperature range for which measurements of the vapor pressure of CeI3 have been made. The vapor pressure of the CeI3 monomer above the pure CeI3 salt for temperatures exceeding its melting point can be approximated by log10p=Pa 11.24(±0.03) - 10,690(±40) (T/K)-1 where the numbers in parentheses are standard uncertainties. InI and T1I were shown to modestly enhance the presence of Ce in the vapor phase, up to a factor of 5. GaI3 produced no enhancement in this temperature range. Numerical simulations of the thermochemical equilibrium suggest the importance of both liquid-phase and vapor-phase complexes. Significant improvement to the method of absolute calibration is discussed. [ABSTRACT FROM AUTHOR]

The vapors in equilibrium with condensates of DyI3, DyI3/InI, TmI3, and TmI3/TlI were observed over the temperature range from 900 K to 1400 K using x-ray induced fluorescence. The total densities of each element (Dy, Tm, In, Tl, and I) in the vapor, summed over all atomic and molecular species, were determined. Dramatic enhancements in the total vapor densities of Dy and Tm were observed in the vapors over DyI3/InI and TmI3/TlI as compared to the vapors over pure DyI3 and pure TmI3, respectively. An enhancement factor exceeding 10 was observed for Dy at T ≈ 1020 K, decreasing to 0 at T ≈ 1250 K. An enhancement factor exceeding 20 was observed for Tm at T ≈ 1040 K, decreasing to 0 at T ≈ 1300 K. Such enhancements are expected from the formation of the vapor-phase hetero-complexes DyInI4 and TmTlI4. Numerical simulations of the thermo-chemical equilibrium suggest the importance of additional complexes in liquid phases. A description of the measurement technique is given. Improvements in the absolute calibration lead to an approximately 40% correction to previously reported preliminary results [J. J. Curry et al., Chem. Phys. Lett. 507, 52 (2011); Appl. Phys. Lett. 100, 083505 (2012)]. [ABSTRACT FROM AUTHOR]

The use of x-ray induced fluorescence to measure elemental densities in a metal-halide lighting arc is described. High-energy synchrotron radiation generated on the Sector 1 Insertion Device beam line at the Advanced Photon Source induces K-shell fluorescence in a high-pressure plasma arc. The detected fluorescence is spectrally resolved, so that multiple elemental species are observed simultaneously. Absolute calibration of the measured densities is straightforward and robust. The penetrating nature of high-energy photons allows these measurements to be made in situ, with the arc contained by an optically translucent polycrystalline alumina (Al[sub 2]O[sub 3]) arc tube and a glass vacuum jacket. Spatial distributions extending from one end of the arc tube to the other and from the arc core all the way to the wall have been obtained for all the principal elements in the arc. A volume element measuring 1 mm × 1 mm × 1 mm is resolved in the present work, with significantly better spatial resolution possible. Densities as low as 2 × 10[sup 16] cm[sup -3] have been observed. X-ray induced fluorescence is useful for the observation of many important high-pressure plasma lighting chemistries including those containing Hg, Tl, Dy, Tm, Ho, Cs, Sn, I, and Xe.
