Radio Frequency -Micro-Electro Mechanical System Switches for Wireless Communication

Abstract: This paper deals with the RF-MEMS switches importance in the wireless communication system. Also explains the dominance of RF-Switch over existing devices like PIN Diodes and Field-Effect-Transistors with power, isolation, size, insertion loss, and how Pull-in voltage affects on the tip deflection of the switch; and how they can be effectively used for future Smart technology Applications

Overlap of dengue fever and HELLP syndrome in pregnancy: a complex clinical encounter

Dengue fever is an arboviral infection caused by the bite of an infected Aedes mosquito, common in tropical areas, especially in India. It is characterized by fever, fatigue, malaise, joint pain, retrobulbar pain, abdominal pain, and thrombocytopenia. It is often complicated by bleeding manifestations like petechiae, bleeding gums, and blood in vomitus. Hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome is usually a complication of preeclampsia in pregnancy (elevated blood pressure after 20 weeks of gestation) and is characterized by hemolysis, elevated liver enzymes, and low platelet count. This is the case of a primigravida that presented at 32 weeks + 2 days of gestation with dengue fever in the background of HELLP syndrome. Significant overlap in the features of dengue fever and HELLP syndrome can lead to a delay in the diagnosis of HELLP syndrome and its management. This case highlights the importance of early recognition of HELLP syndrome in a dengue positive pregnant patient

An unusual dog bite in an infant with penetrating brain injury and scalp loss

The spectrum of bites varies from superficial scraches till deep avulsion of tissues. Children especially infants , because of inherent inability to defense against dogs , are more liable to get their bites. We report an interesting case of dog bite in a 5 months old infant

Post-operative aspergillosis

ABSTRACTWhile invasive aspergillosis occurs typically in severely immunocompromised patients, cases of surgical site infection have been reported in immunocompetent individuals. The Medline, LILACS and EMBASE databases were searched for descriptions of cases of post-operative aspergillosis, and references from relevant articles and conference abstracts were reviewed. More than 500 cases of post-operative aspergillosis were found. Cardiac surgery (n = 188), ophthalmological surgery (n > 90) and dental surgery (n > 100) were associated with the majority of cases. Other cases involved wound infections (n = 22), bronchial infections (n = 30), mediastinitis (n = 11), pleural aspergillosis (n = 1), infections following orthopaedic surgery (n = 42), vascular prosthetic surgery (n = 22), breast surgery (n = 5), abdominal surgery (n = 10) and neurosurgery (n = 25). In most patients, the source was presumed to be airborne infection during the surgical procedure. Prevention of these infections requires special care of the ventilation system in the operating room. Successful treatment requires rapid diagnosis, surgical debridement and antifungal therapy, often with voriconazole. In order to improve the outcome, better diagnostic methods are needed, particularly for cases of endocarditis and aortitis
