  • Universal design equations are presented for the H-plane T-junction power divider with a circular conducting post in a rectangular waveguide. For a given operating frequency and power split ratio, the post offset from the T-junction center line, the distance between the post and the waveguide wall, and the post diameter can be adjusted to obtain a minimum reflection at the input waveguide. Optimum values of the post offset are given in terms of the normalized frequency and the power split ratio. Corresponding values of the post diameter and the distance of the post from the waveguide wall are given in terms of the normalized frequency and the post offset.

  • Background: The purpose of the article was to analyze the years of potential life lost (YPLL) of women who died from breast and cervical cancer in the State of Paran$\acute{a}$, Southern Brazil. This was a temporal trend study (2000 to 2010) about the coefficients of mortality and the years of potential life lost in women aged 20 to 70 years. Materials and Methods: Data were obtained through the database of the Department of the Unified Health System (DATASUS) and the National Mortality Information System. Results: There was a loss of 125.075 YPLL due to breast cancer, with an average of 11.370 YPLL. Regarding cervical cancer, the figure obtained was 91.625 YPLL from 2000 to 2010, with an average of 8.329 YPLL. Increased risk of death from breast cancer was observed for women aged 50 to 59 years, with a significant increase among those in the age group from 40 to 49 years. There was an increased rate of cervical cancer among women 40 to 69 years. Conclusions: The risk of death grows with increasing age, being higher from 40 years. Prevention is paramount for both cancers. Thus, preventive measures are required and a reassessment of political strategies should be adopted.

  • Percutaneous techniques for femoral arterial access are increasingly being performed due to advances in endovascular cerebral procedures, as they provide a less morbid and minimally invasive approach than open procedures. Common complications associated with this peripheral puncture include hematoma, bleeding, pseudoaneurysm, arteriovenous fistula, retroperitoneal bleeding, inadvertent venous puncture, dissection, etc. The retrograde femoral access is currently the most frequently used arterial access as it is technically straightforward, allows for the use of larger size sheaths and catheters, allows repeated attempts, etc. Although being technically less challenging, grave complications can occur due to hardware failure. Here, we present a case of unruptured posterior inferior cerebellar artery (PICA) aneurysm, who underwent uneventful diagnostic cerebral digital substraction angiography (DSA) via right femoral artery route on first attempt, but on second attempt for therapeutic intervention, landed up with stuck guide wire and faced decannulation difficulty due to unravelling of guide wire and multiple knot formation, which was finally removed after multiple attempts at pulling and improvised manoeuvres. Such cannulation and decannulation difficulties have been reported multiple times for central venous access, but extremely rarely for femoral routes, making this case a rarity and worth reporting.

  • Clinical manifestations of extralymphatic disease caused by filariasis are varied and range from symptoms due to tropical pulmonary eosinophilia to hematuria, proteinuria, splenomegaly, and rarely arthritis. Disseminated microfilaremia in association with loculated lung cyst and empyema is of rare occurrence and to the best of our knowledge has not been documented in the literature so far. We report here a case of disseminated microfilaremia due to Wuchereria bancrofti infection accompanied by a lung cyst and empyema in a 21-year-old Indian man.

  • A mixture of several detoxified bacterial strains ($Sterodin^{(R)}$) has been studied for anti-inflammatory effect in Wistar rats on carrageenin, dextran and prostaglandin $E_1$ ($PGE_1$) induced edema in acute model and cotton pellet and carrageenin induced sub-acute model, while, Freund's adjuvant induced chronic model. The bacterial strains showed strong inhibitory activity in acute, sub-acute and chronic models of inflammation. Further, it reduced ${\alpha}1$ acid glycoprotein and ${\alpha}2$ macroglobulin levels in serum and prostaglandin $E_2$ in inflamed paw. These results indicated that the bacterial strains probably act through prostaglandin mediatory pathways and may be useful in treatment of inflammation.
