Problem-Based Learning Research in Anesthesia Teaching: Current Status and Future Perspective

The teaching curriculum in anesthesia involves traditional teaching methods like topic-based didactic lectures, seminars, and journal clubs; intraoperative apprenticeship; and problem-based learning (PBL) and simulation. The advantages of incorporating PBL in anesthesia teaching include development of skills like clinical reasoning, critical thinking, and self-directed learning; in addition it also helps in developing a broader perspective of case scenarios. The present paper discusses the characteristics, key elements, and goals of PBL; various PBL methods available; lacunae in the existing knowledge of PBL research; its current status and future perspectives in anesthesia teaching

Indirect inguinal hernia masquerading as a Spigelian hernia

Inguinal hernia usually developed and descended into scrotum. The clinical presentation is inguinal or inguino-scrotal swelling. Abdominal wall weakness as it is frequently seen in African tropical zones produces often rare clinical case. We report a case of inguinal hernia presented as an abdominal wall swelling clinically suggestive of a Spigelian hernia and discuss the mechanism

Chiral Soliton Model vs Pentaquark Structure for \Theta (1540)

The exotic baryon $\Theta^+$ (1540 MeV)$is visualised as an expected (iso) rotational excitation in the Chiral Soliton Model. It is also argued as a Pentaquark baryon state in a constituent quark model with strong diquark correlations. I contrast the two points of view; the similarities and differences between the two pictures. Collective excitation, characteristic of Chiral Soliton Model points toward small mixing of representations in the wake of SU(3) breaking. In contrast, Constituent quark Models prefer near ``ideal'' mixing, similar to$\omega - \phi$ mixing.Comment: 11 pages, references added, final published versio

Experiences with chest trauma: where do we stand today

Background and Aims: Chest trauma is a major public health problem in India, but only few studies have been conducted to analyze its magnitude and management. The present study was carried out to determine the epidemiological profile of chest trauma cases and to analyze the management strategies with an aim to identify the scope of improvement in our set-up. Materials and Methods: It is a retrospective study of cases admitted with chest trauma, to a tertiary care hospital. Records of the patients admitted to the hospital with chest trauma over a period of one year were analyzed for the patients′ demographic profile; mechanism, nature and severity of injuries; associated injuries; management and outcome of cases. Results: Out of a total of 105 patients, most were males, belonged to age group of 21-40 years and suffered blunt trauma. Motor vehicle accident was the commonest mechanism of injury. The interval from injury to admission ranged from one hour, to more than 24 hours. Eight patients were admitted to the ICU, out of which 5 required ventilatory support. The most frequently used analgesics in the wards were non-steroidal anti-inflammatory drugs (NSAID). Ninety one patients improved, while seven patients died in the hospital. Conclusions: Chest trauma due to blunt injury is an important cause of morbidity and mortality in young males. Despite limitations of resources and manpower, attempts are being made to manage patients successfully. However, creation of dedicated trauma teams with well-designed management protocols in hospitals can further improve the outcome

Design of a novel and efficient lantern wind turbine

Wind turbine generates renewable energy when the forces acted on the turbine blades cause the rotation of the generator to produce clean electricity. This paper proposed a novel lantern wind turbine design compared to a conventional design model. Comparison is done based on simulation on coarse and fine meshing with all the results converged. Results showed that the pressure difference on the surface of novel design lantern wind turbine is much higher compared to the conventional wind turbine. Prototype is already manufactured and experimental result would be discussed in a separate future publicatio
