Cardiac Valvular Inflammatory Pseudotumor

Inflammatory pseudotumors are quasineoplastic lesions that occur in the lungs as well as other extrapulmonary sites. The heart is an uncommon site of origin. We report a valvular pseudotumor that produced chronic mitral and aortic regurgitation in an elderly woman

Malignant retroperitoneal teratoma in a young girl: a rare case report

Of all primary retroperitoneal teratomas, less than four percent occur in children and 90% are benign. Here we report a case of malignant retroperitoneal teratoma (dermoid) in a 15 year old girl who presented to our hospital - Acharya Vinoba Bhave Rural Hospital (AVBRH). She presented with a tender, large, irregular mass with variegated consistency in the entire left side of abdomen crossing midline. Ultrasound of abdomen suggested a complex intra-abdominal mass with septations and lobulations. It was not feasible to use other imaging modalities for evaluation due to poor socio-economic status and illiteracy. Patient underwent exploratory laparotomy with tumor resection along with left kidney and part of the descending colon which was densely adhered to tumor. Histopathological examination of tumor was suggestive of immature teratoma. Post operative recovery was uneventful and patient was discharged from the institution. Tissue adherence which can be observed in both benign and malignant form of teratomas, requires extended surgery for removal of adhered organ for the completeness of surgery and good prognosis

A unified approach for prediction of thermodynamic properties of aqueous mixed-electrolyte solutions. Part I: vapor pressure and heat of vaporization

The overall nonideality of an aqueous mixed electrolyte solution is characterized in terms of a newly defined parameter Γ*, called the overall reduced ionic activity coefficient. It is shown that Γ* for the mixed solution is simply related to the properties of single-electrolyte solutions. Γ* is related to the vapor pressure of a mixed-electrolyte solution through well-known thermodynamic equations. This leads to a predictive equation for the vapor pressure of a mixed-electrolyte solution in terms of the vapor pressures of single-electrolyte solutions of the components. This equation is valid over the entire concentration range encountered in practice, without any empirical constants, and has a predictive accuracy of 2%. A predictive equation for the latent heat of vaporization is also developed and tested against experimental data

A unified approach for prediction of thermodynamic properties of aqueous mixed-electrolyte solutions. Part II: volume, thermal, and other properties

The overall reduced ionic activity coefficient Γ* is useful in characterizing the overall nonideality of an aqueous mixed-electrolyte solution. It has been shown in Part I that Γ* can be simply related to Γ of single-electrolyte solutions containing the component electrolytes without using empirical constants. This basic relationship is used in this paper for deriving predictive equations for several properties in terms of corresponding properties of single-electrolyte solutions containing the component electrolytes. The predictive equations need no empirical constants. The properties covered include volume properties such as density and adiabatic compressibility, thermal properties such as enthalpy and specific heats, and others such as free energy, expansibility, and depression in freezing point. Comparison with experimental data shows that the predictive equations have an accuracy varying from 0.03% for density to 2% for freezing point depression, and are valid for the entire range of concentrations encountered in practice

Prediction of vapour pressure of aqueous solutions of single and mixed electrolytes

A simple method is proposed for estimating the vapour pressures of aqueous single electrolyte solutions at 25°C. The method is based on a single empirical parameter, K. The treatment is extended to include different temperatures as well as solutions of mixed electrolytes. The estimation of vapour pressures in mixed solutions requires knowledge of the K values of constituent electrolytes and the vapour pressure of aqueous solutions of two reference electrolytes, viz. LiBr and NH4NO3 at 25°C. The calculated vapour pressures of single and mixed electrolyte solutions are in agreement with experimental data within 1.6% in general
