Students' perceptions on newly designed foundation course at MBBS entry level: A mixed-method study.

Background: Selection of students to medical colleges is based on merit of candidate at written entrance examination which does not take care of nonscholastic abilities of the students. Medicine is a profession that requires not only mastery of large body of knowledge and clinical skills but also high standards of professionalism and appropriate attitudes. Methodology: A 1-month long foundation course was conducted for the fresh students admitted to MBBS course at Andaman and Nicobar Islands Institute of Medical Sciences, Port Blair, India. Seventy-four students had joined the course. The course was planned, arranged, and executed by the department of Medical Education Unit. It included six modules. Retrospective pre- and postevaluation was done for knowledge, skill, and attitude. Wilcoxon signed-rank test was used for all pair-wise comparisons. Participants also completed a questionnaire (Likert scale and some open-ended items) about educational quality of sessions and utility of the course. Descriptive statistics and qualitative methods were used for data analysis. Results and Conclusion: Response rate was 100%. Students perceived foundation course as an excellent opportunity to acquire basic knowledge, attitude, and skills required for subsequent phases in MBBS course. This Foundation Course enhanced their orientation to the curriculum and campus, boosted confidence to cope up with the challenging syllabus, helped them develop time and stress management skills, and also sensitized them to achieve the highest standards of morale required to ensure ethical practice.

Disseminated Strongyloidiasis: Breaking Brain Barriers.

Strongyloides stercoralis (SS) is one of the most overlooked helminthic infections despite being highly endemic in tropical and subtropical areas. In immunocompromised patients, especially those on long-term steroids, infection can often escalate to fatal dissemination into major organs. We present a compendium of two immunocompromised patients, who were on high-dose steroids and presented with worsening neurological status. Cerebrospinal fluid analysis was notable for larvae of SS as diagnosed by direct visualization. A syndrome of SS hyperinfection with dissemination was made after stool, and sputum samples also revealed SS larvae. SS is an elusive disease and should be considered early on, especially in endemic regions like India. Early diagnosis and prompt initiation of antihelminthic therapy is indispensable for favorable outcomes.

Clinical Profile of Pneumocystis jirovecii Infection - A Comparative Study.

Objectives: Pneumocystis jirovecii pneumonia (PCP) can differ in HIV and non HIV population due to degree of immunity. This study was undertaken with an aim to highlight the differences between the two groups. Methods: It was an observational study conducted in the department of Medicine of a tertiary care institution in North India. All cases tested positive for Pneumocystis jirovecii from January 2009 to December 2014 were included in the study. Demographic profile, clinical presentation, risk factors, treatment and course in hospital were noted and analyzed. Results: Among the 42 patients who had PCP, 13 (30.9%) patients were HIV positive and 29 (69%) were HIV negative.Cough was seen maximum in 10(79.3%) patients in HIV group compared to non HIV whereas fever and breathlessness predominated in the non HIV group. The outcome was better in the non HIV group compared to the HIV group which was 16 (55.2%) versus 6 (46.1%) patients respectively. Conclusion: Clinical presentation differed slightly in both these groups. Difference in the outcome was also noted, however, larger numbers may be required to show the difference. It may form the basis of further research. The study successfully compared the presentation and outcome of PCP in the two groups.

Epidemiological and mycological characteristics of candidemia in patients with hematological malignancies attending a tertiary-care center in India.

BACKGROUND AND OBJECTIVES: We undertook the present study to ascertain the contributing risk factors and explore the epidemiological and mycological characteristics of opportunistic candidemia among patients with hematological malignancies. DESIGN AND SETTINGS: Observational cross-sectional study in a tertiary care center. PATIENTS AND METHODS: Consecutive patients with hematological malignancies reporting to the collaborating medical and pediatric units with a febrile episode were recruited and screened for candidemia by blood culture. Recovered Candida isolates were speciated and antifungal susceptibility testing was performed as per Clinical and Laboratory Standards Institute guideline (CLSI) guidelines M44-A. Further analysis was done for potential risk factors and compared between culture positive and negative patients. RESULTS: Of 150 patients recruited, the majority (n=27) were between 51 and 60 years and the male to female ratio was 1.63:1. Fifteen patients (10%) were culture positive. The culture positivity was significantly higher in acute lymphocytic leukemia (ALL) than in non-ALL patients (p=0.03). There was significant association of candidaemia with leucopenia, chemotherapeutic drugs, corticosteroids and presence of indwelling devices. Duration of disease (p=0.032) and duration of hospitalization (p=0.003) were significantly prolonged in culture positive patients. C. tropicalis was the commonest isolate (46.67%), with non- Candida albicans outnumbering C. albicans in all categories of hematological malignancies (2.75:1). All isolates of C. albicans were uniformly sensitive to all the azoles, but only 50% were sensitive to amphotericin B and none to nystatin and flucytosine. CONCLUSIONS: This observational study identifies ALL and chronic lymphocytic leukemia (CLL) as the forms of hematological malignancy predominantly associated with candidemia; specifies risk factors and chemotherapeutic agents predisposing patients towards its occurrence; reports a preponderance of C. tropicalis among the causative agents and finds voriconazole to be the most effective antifungal agent against the recovered isolates. This information could assist in tailoring prophylactic and therapeutic antifungal practices for this infection, according to local epidemiological and mycological characteristics.

Scrub typhus-an emerging entity: a study from a tertiary care hospital in North India.

Scrub typhus is a tropical febrile zoonotic disease caused by Orientia tsutsugamushi of the rickettsial family. These are obligate; intracellular Gram-negative coccobacilli transmitted by the bite of infected mites. It is usually under-diagnosed in India due to its varied and nonspecific clinical presentation, limited awareness, and low index of suspicion among clinicians and lack of diagnostic facilities. This study was planned to monitor the level of scrub typhus-specific antibodies among febrile patients in a tertiary care hospital over a period of 1 year for which a rapid qualitative immunochromatographic assay (Standard Diagnostics, Korea) was introduced for the detection of IgM, IgG and IgA antibodies to O. tsutsugamushi from the serum of suspected febrile patients. A total of 98 out of 772 fever patients (12.69%) tested positive for the presence of antibodies against O. tsutsugamushi. Persistent high-grade fever was the defining characteristic in all the cases with the presence of an eschar in only 10.2% (10/98) of cases. Three patients died during the study period while the rest responded to treatment with doxycycline.

Scrub typhus in Punjab: an acute febrile illness with multisystem involvement.

Scrub typhus is an important cause of acute febrile illness. This observational study describes the clinical features and complications of the patients diagnosed to have scrub typhus in Christian Medical College & Hospital, Ludhiana, Punjab, India. The diagnosis of scrub typhus was made by using Bioline SD Tsutsugamushi test kit which detects IgM, IgG or IgA antibodies to Orientia tsutsugamushi. Sixty-two patients of scrub typhus were seen during the study period of 1 year. The mean age of the study group was 39.9 years. All the patients presented with fever, and of these 31 (50%) had non-specific symptoms. All others had some complication, namely ARDS/ALI in 18 (29%), neurological involvement in 12 (19.4%), acute kidney injury (AKI) in 16 (25.8%), hypotension in eight (12.9%), thrombocytopenia in 23 (37.1%), hepatitis in 34 (54.8%) and MODS in 19 (30.7%). Eschar was present only in nine patients. Three patients expired due to multi-organ failure, hypotension and metabolic acidosis.

Acinetobacter infections in a tertiary level intensive care unit in northern India: epidemiology, clinical profiles and outcomes.

BACKGROUND: Nosocomial Acinetobacter infections are an increasing concern in intensive care units (ICU). OBJECTIVES: To study the demographic and clinical characteristics and the outcomes of ICU patients with Acinetobacter infections. METHODS: A retrospective, 1-year audit of all Acinetobacter infections diagnosed in ICU patients between January 1 and December 31, 2009. RESULTS: Acinetobacter infection occurred in 94 patients (108 episodes). The most common site of infection was the respiratory tract (83 patients, 76.85%), with medical patients being more susceptible than surgical patients to Acinetobacter lung infections (P=0.04), particularly late-onset ventilator-associated pneumonia (VAP) (P=0.04). The majority (63.8%) of infections were acquired in the ICU, and patients with ICU acquired infections were intubated significantly longer than the other patients (P=0.02). Seventy percent of the infections were caused by multidrug-resistant (MDR) strains, and the overall crude mortality rate was over 70%. The most important factors affecting mortality were the duration of intubation (P=0.001) and the inappropriate use of antibiotics (P=0.021) after diagnosis of the infection. CONCLUSIONS: Acinetobacter infections are highly prevalent in the ICU, with medical patients being more susceptible to lung infections, particularly late-onset VAP. The early and appropriate selection of antibiotics is the most important determinant of survival among these patients.
