45 year old female with altered sensorium secondary to dengue encephalitis

G. Sai Manogna 
Roll No 33 

 This is an online E logbook to discuss our patient's de-identified health data shared after taking her guardian's signed informed consent. Here we discuss our individual patient's problems through series of inputs from an available global online community of experts to solve those patient's clinical problems with collective current best evidence-based inputs. This e-log book also reflects my patient-centred online learning portfolio and your valuable inputs on the comment box are welcome. 

 Following is the view of my case: A 45-year-old woman, a farmer by occupation from Nalgonda has come to the OPD with the chief complaints of 
* Fever for 3 days 
*Vomitings since 2 day 
*ALtered sensorium since 1 day

History of presenting illness:

In the month of February 2021, the patient has experienced lower abdominal pain for which she visited a hospital and was diagnosed as CA cervix and then hysterectomy was done after which the patient was normal. 

She was apparently asymptomatic 3 days ago and then developed a high-grade fever which was insidious in onset and intermittent in type and was associated with chills and rigours

H/o vomiting 2 days ago with 5-6 episodes per day which was non-bilious, non-projectile, non-blood-tinged and were semi solid in consistency

Patient has come to the OPD with loss of alertness,disorientation, poor judgement or thinking and disturbances in perception and behaviour

The patient was taken to an outside hospital where she was diagnosed as NS1 dengue positive and was referred to Kamineni for further management
