In patients with SSICH, mortality was found to be significantly associated with the treatment arm and the results were in favour of SM among the patients presenting with GCS 4-8, hematoma volume 31-60 ml, midline shift of more than 5 mm, and intraventricular extension of the hematoma.

Medulloblastoma is a common tumor of the posterior fossa, representing 20-25% of all pediatric neoplasms. It commonly occurs in the midline (cerebellar vermis) and rarely at the cerebellopontine angle. Most of them are intra-axial, and an extra-axial location of this tumor is very rare. Extra-axial cerebellopontine angle medulloblastoma is extremely uncommon and has never been reported in an infant. We report an extra-axial cerebellopontine anglemedulloblastoma in a 1-year-old child.

We came across a case of jugular foramen mass causing positional hoarseness on turning the head left and disappearing on returning the head to a straight position. Hoarseness of voice due to vagus nerve involvement is seen in jugular foramen mass but positional hoarseness has never been seen before. We report this rarest presentation and discuss the pathophysiology behind it.

This paper present the analysis of tuning the parameters of PID controller applied to load frequency control problem. In case of an interconnected power system, any small sudden load change in any of the areas causes the fluctuation of the frequencies of each and every area and also there is fluctuation of power in tie line. For satisfactory operation of a power system, frequency should remain nearly constant. Frequency deviations can directly impact on a power system operation, system stability, reliability and efficiency. Large frequency deviations can damage equipments, degrade load performance, overload transmission lines and affect the performance of system protection schemes. These large-frequency deviation events can ultimately lead to a system collapse. A Load Frequency Control (LFC) scheme basically incorporates an appropriate control system for an interconnected power system, which is heaving the capability to bring the frequencies of each area and the tie line powers back to original set point values or very nearer to set point values effectively after the sudden load change. This can be achieved by the use of conventional and modern controllers. Modern controllers have a lot of advantages over conventional integral controller. They are much faster than integral controllers and also they give better stability response than integral controllers. In this proposed research work PID controller has been applied for LFC of two area power systems. The parameters of the PID controller are tuned by two different methods names as (1) Ziegler-Nichols (Z-N) Method and (2) Simplex Search Method for better results. It is seen that the results obtained are far better than the conventional controller.
