Human Dipylidiasis: A Case Report of Dipylidium caninum Infection from Karimnagar.

Dipylidium caninum also refered to as the double-pored tapeworm is a cyclophyllidean cestode that commonly infects dogs and cats. Mammals act as definite hosts with intermediate hosts being dog and cat flea, the Ctenocephalides canis and Ctenocephalides catis respectively. The dog lice, Trichodectes canis and human flea (Pulex irritans) also transmit Dipylidium caninum infection. Infants and young children are at high risk of acquiring infection. Majority of the infections are due to close association with pet dog and cats. Humans are accidental hosts who acquire infection by ingestion of infected dog and cat fleas. We report a rare case of Dipylidium caninum infection in a 9 year old girl who could have acquired infection by consuming food contaminated with infected fleas

Rheological Behavior of Coal-Water Slurries

The rheological behavior of coal-water slurries was stud ied, using a Brookfield Rheolog viscometer with a thermosel system to maintain constant temperature. The coal used for making up the slurries was Sarpy Creek subbituminous coal from Montana. The effect of particle size, slurry concen tration and hot water drying process on the rheology was in vestigated. The particle size used ranged from 0.223 mm to 0.044 mm mean particle diameter, and the solids concentra tion in the slurry varied from 15 to 70 weight %. Tempera ture was maintained at 28 C (82 F). Coal-water slurries exhibited a pseudoplastic behavior. The behavior of coal-water slurries was described accurately by a power law model of the form t = a(R)b where 1t \u27 is the shear stress, \u27R\u27 is the shear rate and \u27a\u27 and \u27b\u27 are experimentally determined constants. It was seen that apparent viscosity increased with an increase in solids concentration. It was also observed that the coeffi cient \u27a\u27 increased with an increase in solids concentra tion, while the exponent ’b\u27 did not show any definite pat tern in its variation. The moisture content of the hot water dried coal was de termined to be 13%, as compared to 25% for the unprocessed coal (as received coal). The slurry made with hot water dried coal showed a pseudoplastic or shear thinning behav ior, and it was seen that the apparent viscosity of hot wa ter dried coal-water slurries was lower than the apparent viscosity of unprocessed coal-water slurries. Sedimentation characteristics of coal-water slurries were also studied by using a specially designed sedimentation ap paratus. The settling rates of coal particles were found to vary inversely with increase in slurry concentration, and directly with particle size. The particle sizes used were the same as those used for obtaining the rheology data. Hot water dried coal-water slurries exhibited negligible set tling

Hall Effect in the Viscous Incompressible Flow Through a Rotating Channel Between Two Porous Walls

Exact solutions for the velocity and induced magnetic field distributions, accounting for Hall currents have been obtained for the flow of a conducting porous walls under the action of a constant pressure gradient and in the presence of a uniform magnetic field transversely applied to the flow. Further, the channel is rotated with constant angular velocity about an axis perpendicular to the walls. For the purpose of mathematical simplicity, the magnetic prandtl number is assumed to be negligible. An expression for the boundary layer thickness dependent on Taylor, Hartmann, suction Reynolds numbers and Hall parameter has been obtained

An evaluation of the practice of active management of third stage of labour in a teaching hospital

Background: Worldwide post-partum haemorrhage (PPH) is the most common cause of maternal mortality. Atonic PPH accounts for 80% of the cases. Risk of PPH can be reduced by 60% by actively managing the third stage of labour. International Federation of Gynecology and Obstetrics (FIGO), International Confederation of Midwives (ICM) and World Health Organization (WHO) recommend routine use of active management of third stage of labour (AMTSL). The present study was done to evaluate the practices of AMTSL.Methods: 100 Case sheets of women who had vaginal delivery were randomly taken and analyzed for the data regarding the components of AMTSL. Microsoft excel was used for analysis.Results: The main component of AMTSL, Oxytocin 10 IU IM was used in 80% of the cases for prevention of PPH. Methylergometrine was used in 20% of the cases. Documentation of controlled cord traction was not present. Uterine massage was not routinely done and documented.Conclusions: WHO recommends all the components of AMTSL and uterotonic is the most significant component. Controlled cord traction should be used where trained person is available. It is necessary to train the staff and create awareness about the AMTSL. Correct documentation is essential for feedback and auditing. Methylergometrine should be used as a second line drug for the treatment of post-partum haemorrhage

Photoplethysmography

The process of breathing occurs as a physiological cycle in which one nasal cavity is functionally active while the other is resting, i.e., breathing alternates between the nostrils according to a regular pattern referred to as the "nasal cycle" and this cycle has been found to have a profound effect on a number of brain functions. It is suspected that some cross coupling exists between the dominant nostril and the active cerebral hemisphere. It is believed that breathing has a profound effect on man's physical/psychological functioning and is the link between the body and the mind. Pranayama is a well-proven technique for controlled rhythmic breathing with beneficial effects reported both for the body and the mind. In this study the arterial blood volumetric changes from 10 normal breathing subjects and 30 subjects practicing pranayama are monitored non-invasively at the earlobes using optical sensors. This method is known as Photoplethysmography (PPG). Spectral analysis and Heart Rate Variability (HRV) studies are performed on the collected PPG data. The results show fundamental changes in the spectral components of the PPG signal in relation to the breathing brought about by pranayama. In addition, a bi-nasal respiratory airflow monitor is designed and developed for this study utilizing miniature thermistors that can be introduced into the two nostrils of the subject without causing discomfort to the subject. Another study is also reported in which changes in microcirculation in chakra points were studies as a result of concentration on these points. Results indicate the low frequency component around 0.18 Hz changes dramatically during these procedures. Concentration on heart increases the amplitude of the low frequency by about 4.5 times. Concentration on the eyebrow chakra increases the value of this component by about 3 times, but the curve is much broader showing more "power" in that band of frequencies. Since prana or chi is related to amount of blood flow, it is likely the increase in microcirculation is related to increase in prana, as suggested in ancient texts. Further work is contemplated to peruse this line of thinking through standard clinical methods
