Background Enteric fever is very common infectious disease in developing countries like Nepal. Due to lack of resources diagnosis has to be clinical most of the time. Hence a proposal of clinical diagnostic criteria and validation of the same would be very useful. Objective To validate the proposed clinical diagnostic criterion including features characterized as major and minor criteria Methods This study was done in the department of medicine of Kathmandu Medical College Teaching hospital, from June 2009 to January 2012. A total of 114 patients presenting with fever were included in the study. After proposal of clinical diagnostic criteria for enteric fever, by a prior published study, all the fever patients were grouped according to criteria positive or negative. The most significant criteria were validated by calculating sensitivity and specificity along with positive and negative likelihood ratios with blood culture taken as gold standard. Results A total of 114 patients were enrolled. Total patients diagnosed as enteric was 47.3 %. Clinical diagnostic criterion B which included three major (headache, fever and relative bradycardia) and three minor criteria (abdominal pain, vomiting, diarrhea, splenomegaly and chills) was highly significant (p=<.0001) in diagnosing enteric fever and had a sensitivity of 72.2% ( 95% CI 58.1- 83.1) and specificity of 98.3% ( 95% CI 89.8-99-9). The positive likelihood ratio was 43.33 (95 % CI 6.16-304.77) and negative likelihood ratio as 0.28 (95% CI 0.18-0.43). Conclusion Clinical diagnostic criteria can be a very useful tool for diagnosis of enteric fever when culture facility is not available.

The RR and its derivative indices are easily accessible vital signs monitored at the ED which merit 'revitalization'.

The N/L ratio, a cheap and easily assessed biomarker, warrants further investigation as a potential diagnostic tool for the ED physician facing dyspnoeic CHF patients.

Background Electrocardiographic (ECG) changes are frequently reported findings in patients with subarachnoid hemorrhage (SAH). We conducted a retrospective descriptive study to assess the prevalence of electrocardiographic changes in patients with non-traumatic SAH. Methods In this single-center retrospective cross-sectional study, ECG recordings of 45 patients who presented to Tribhuvan University Teaching Hospital in the year 2019 with SAH were collected and analyzed to detect any abnormalities. Results In our study, 88.8% of patients had some form of ECG abnormality. The most common ECG abnormalities associated with SAH were QTc prolongation, T-wave abnormalities, and bradycardia, which were found, respectively, in 35.5%, 24.4%, and 24.4% of the patients. Other ECG changes we observed include ST depression, large U-waves, atrial fibrillation, and premature ventricular contractions. Conclusion Morphological and rhythm abnormalities are frequently observed in patients with SAH, which may cause diagnostic dilemmas and unnecessary workups. Further studies are required to evaluate their significance and correlate ECG changes with clinical outcomes.
