RESUMEN
Meningitis and encephalitis are the neurological emergencies. As the clinical findings lack specificity, once suspected, cerebrospinal fluid (CSF) analysis should be performed and parenteral antimicrobials should be administered without delay. Lumbar puncture can be technically challenging in patients with ankylosing spondylitis due to ossification of ligaments and obliteration of interspinous spaces. Here, we present a case of ankylosing spondylitis where attempts for lumbar puncture by conventional approach failed. CSF sample was successfully obtained by Taylor's approach.
RESUMEN
Apnea testing is a key component in the clinical diagnosis of brain death. Patients with poor baseline oxygenation may not tolerate the standard 8-10 min apnea testing with oxygen insufflation through tracheal tube. No studies have assessed the safety and feasibility of other methods of oxygenation during apnea testing in these types of patients. Here, we safely performed apnea testing in a patient with baseline PaO2 of 99.1 mm Hg at 100% oxygen. We used continuous positive airway pressure (CPAP) of 10 cm of H2O and 100% oxygen at the flow rate of 12 L/min using the circle system of anesthesia machine. After 10 min of apnea testing, PaO2 decreased to 75.7 mm Hg. There was a significant rise in PaCO2 and fall in pH, but without hemodynamic instability, arrhythmias, or desaturation. Thus, the apnea test was declared positive. CPAP can be a valuable, feasible and safe means of oxygenation during apnea testing in patients with poor baseline oxygenation, thus avoiding the need for ancillary tests.
RESUMEN
OBJECTIVE: Electroencephalographic (EEG) abnormalities especially non-convulsive status epilepticus (NCSE) have been found to be associated with worse outcomes in critically ill patients. We aimed to assess the prevalence of non-convulsive seizures and electroencephalographic abnormalities in critically ill patients. Furthermore, we aimed to investigate any association between the type of EEG abnormality and outcomes including ICU mortality and successful ICU discharge. METHODS: This was a cross-sectional observational study carried out among critically ill patients in a mixed medical-surgical ICU from January 1, 2018 to May 15, 2020. A total of 178 records of 30 min bedside EEG records were found. EEG findings were grouped as normal, non-convulsive seizures (NCS), non-convulsive status epilepticus (NCSE), and other abnormalities. Descriptive analytical tools were used to characterize the case details in terms of the type of EEG abnormalities. Chi square test was used to describe the EEG abnormalities in terms of mortality. The status epilepticus severity scores (STESS) were further calculated for records with NCSE. These data were then analyzed for any association between STESS and mortality for cases with NCSE. RESULTS: The prevalence of EEG abnormality in our cohort of all critically ill patients was found to be 7.3% (170/2234). Among the patients with altered sensorium in whom EEG was done, 42.9% had non-conclusive seizure activity with 25.2% in NCSE. Though the study was not adequately powered, there was a definite trend towards a lower proportion of successful ICU discharge rates seen among patients with higher STESS (>2) with only 33.3% being discharged for patients with a STESS of 6 versus 92.9% for those with STESS 3. SIGNIFICANCE: When combined with a strong clinical suspicion, even a 30-min bedside EEG can result in detection of EEG abnormalities including NCS and NCSE. Hence, EEG should be regularly included in the evaluation of critically ill patients with altered sensorium. PLAIN LANGUAGE SUMMARY: Electroencephalographic (EEG) abnormalities and seizures can have high prevalence in critically ill patients. These abnormalities notably, non-convulsive status epilepticus (NCSE) has been found to be associated with poor patient outcomes. This was a retrospective observational study analyzing 178 EEG records, from a mixed medical-surgical ICU. The indication for obtaining an EEG was based solely on the clinical suspicion of the treating physician. The study found a high prevalence of EEG abnormalities in 96.5% in whom it was obtained with 42.9% having any seizure activity and 28.8% having NCSE. The study was not powered for detection of association of the EEG abnormalities with clinical outcomes. However, a definite trend towards decreased chances of successful discharge from the ICU was seen. This study used strong clinical suspicion in patients with altered sensorium to obtain an EEG. High detection rates of EEG abnormalities were recorded in this study. Hence, combination of clinical judgement and EEG can improve detection of EEG abnormalities and NCSE.

Enterovesical fistula represents an abnormal communication between the intestine and bladder. The causes are diverticulitis (56.3%), malignant tumours, which are located mainly in the intestine (20.1%), and Crohn's disease (9.1%). Other causes include iatrogenic injury (3.2%); trauma; foreign bodies in the intestinal tract; radiotherapy; chronic appendicitis; tuberculosis; and syphilis. Normal vaginal delivery as a cause for enterovesical fistula has not been reported in many publications yet. We report a case of a 30-year-old female, who developed an jejunovesical fistula after normal vaginal delivery. It was diagnosed after diagnostic cystoscopy and computed tomography of the abdomen and pelvis. There was jejuno-vesical fistula. Resection of the segment of the jejunum with side-to-side anastomosis with bladder repair was done. A follow-up cystogram was done which showed no contrast extravasation into the peritoneum. The patient was followed up for 9 months after surgery. Keywords: case reports; fistula; jejunum; urinary bladder.

Key clinical message: Delayed presentation of cerebrospinal fluid rhinorrhea is rare following head trauma. It is frequently complicated by meningitis if not addressed in time. This report highlights the importance of its timely management, the lack of which can lead to a fatal outcome. Abstract: A 33-year-old man presented with meningitis in septic shock. He had a history of severe traumatic brain injury 5 years back following which he had a history of intermittent nasal discharge for the past 1 year. On investigation, he was found to have Streptococcus pneumoniae meningitis, and CT scan of his head showed defects in the cribriform plate which established the diagnosis of meningoencephalitis secondary to cerebrospinal fluid rhinorrhea. The patient did not survive despite appropriate antibiotics.
RESUMEN
Primary retroperitoneal masses have numerous differential diagnoses, many of which are rare entities. These can be neoplastic or nonneoplastic. Among the rare conditions are solitary fibrous tumors, which can either be benign or malignant. It is a mesenchymal, spindle-cell tumor, reported first in 1931 as a pleural tumor by Klemperer et al. A 20-year-old lady, with abdominal pain for 6 months, was diagnosed with a retroperitoneal mass on the left lower abdomen on USG which was confirmed by an MRI scan of the abdomen. The patient underwent laparoscopy-assisted excision of the mass. The final histopathological reports and immunohistochemistry reports revealed a solitary fibrous tumor. Solitary fibrous tumors (SFTs) are rare tumors in the retroperitoneum. In our search, fewer than a hundred cases have been reported. It has a characteristic "patternless pattern" in a microscopic study. Adverse outcomes of SFTs are associated with atypical features in histology, such as nuclear pleomorphism, necrosis, increased cellularity, and mitoses >4/10 HPF and size more than 10 cm. The standard of care is surgical excision with clear margins. Open surgeries have been done traditionally; we present a case where we performed the excision laparoscopically.
RESUMEN
BACKGROUND: Ophthalmological examination is an important aspect of the neurological assessment in a patient with traumatic brain injury. However, significant periorbital swelling can make direct visualization of the pupils difficult. Ultrasonic examination can be a valuable bedside tool when direct visualization fails. CASE: A case of a seven-year female child who had presented with a history traumatic brain injury is reported here. OBSERVATIONS: The periorbital swelling prevented the direct visualization of the eyes. Bedside evaluation with a multipurpose ultrasound (USG) was used to monitor the pupillary diameter (PD) and the consensual pupillary light reflex (PLR) at regular intervals. The PD was measured in the B-mode while the PLR was monitored in M-mode of the USG. The optic nerve sheath diameter (ONSD) was also monitored as a correlate of intracranial pressure (ICP). CONCLUSION: Ophthalmic evaluation of PD and PLR can be easily and objectively done on the bedside using USG especially in cases where the direct visualization of the pupils is difficult due to injuries and swelling of the periorbital tissues. Furthermore, ONSD measurements can also be done to monitor the changes in the ICP.
RESUMEN
Hepatic encephalopathy describes a spectrum of potentially reversible neuropsychiatric abnormalities seen in a patient with severe liver dysfunction with porto-systemic shunting. Cortical blindness can be a rare presentation of hepatic encephalopathy and can even precede the onset of altered sensorium. We report a case of 57 years female with chronic liver disease who presented with bilateral loss of vision, with no focal neurological deficits. From clinical and laboratory examination, a diagnosis of hepatic encephalopathy with cortical blindness was proposed. Her visual disturbances gradually improved with the treatment of hepatic encephalopathy. Keywords: Cortical blindness; end stage liver disease; hepatic encephalopathy; papilledema.

Cardiac myxoma is an infrequent but curable cause of ischemic stroke. There are no guidelines addressing the timing of surgery to excise the tumour or for the use of thrombolysis or thrombectomy. We present a case with an ischemic stroke which was diagnosed to have atrial myxoma. She was planned for surgical excision of the tumour but suffered from a second ischemic stroke while awaiting surgery. This article aims to highlight vital aspects of this rare phenomenon and discuss the prospects of the timing of surgery and neurosurgical intervention. The importance of a proper cardiac evaluation in all cases of stroke is highlighted. Keywords: cardiac tumour; myxoma; cardiac surgery; ischemic stroke.

Influenza has a common occurrence during its peak seasons. It usually causes disease of the respiratory tract including severe acute respiratory distress syndrome. However, it may also cause disease and complication of other organ systems. We present a rare complication of influenza in which a patient secondary to influenza developed massive middle cerebral artery ischemic stroke. The patient however survived following recovery of both severe acute respiratory distress syndrome and ischemic stroke after decompressive craniectomy and a prolonged intensive care unit stay. This case report is to highlight the importance of influenza related complications besides the pulmonary infliction which can lead to morbidity and even mortality if not managed on time.

Introduction: Drug interactions are one of the major contributors to increase hospital stay, inflate health care expenses, and cause serious adverse events and end-organ damage. Patients admitted to the intensive care unit are already critically sick and are at greater risk of these adverse outcomes. The study aimed to find out the prevalence of potential drug-drug interactions in the Intensive Care Units of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among the patients admitted in the Intensive Care Unit of a tertiary care hospital from April-June 2019. Ethical approval was taken from the Institutional Review Board at the institute (Reference number: 399). Convenience sampling method was used. Data was collected using proforma and potential drug-drug interactions were identified using Lexicomp® drug-interactions version 1.1 (Wolters Kluwer). All the drug interactions identified were classified and the severity scale of interactions was also defined. Statistical Package for the Social Sciences version 17.0 was used for data analysis. Point estimate at 95% Confidence Interval was calculated along with frequency, percentage, mean, standard deviation, and mode. Results: Out of 101 patients, the prevalence of the drug-drug interaction was found to be 90 (89.11%) (83.04-95.18 at 95% Confidence Interval). A total of 490 drug-drug interactions were identified. In severity scale, it was seen that 311 (63.46%) were of moderate severity and 303 (61.83%) of drug interactions were categorised as category C in risk rating. Conclusions: Prevalence of potential drug-drug interactions was higher compared to similar published literature. The most common drug with potential interaction was fentanyl and among pairs was fentanyl plus paracetamol. Keywords: drug interactions; intensive care units; Nepal; software.

BACKGROUND: Corona virus disease 2019 has become a global health issue. The goal of this study was to investigate the characteristics and outcomes of patients with corona virus disease 2019 undergoing invasive mechanical ventilation and identify factors associated with mortality. METHODS: Ninety four consecutive critically ill patients with confirmed corona virus disease 2019 undergoing invasive mechanical ventilation were included in this retrospective, single-center, observational study. The outcome variable was mortality of patients undergoing invasive mechanical ventilation and factors associated with it during intensive care unit stay. RESULTS: Seventy nine (84%) out of 94 patients with confirmed corona virus disease 2019 who underwent invasive mechanical ventilation didn't survive. Ninety four percent of patients who had Type 2 Diabetes Mellitus did not survive in comparison to 72 percent of patients who didn't have Type 2 Diabetes Mellitus. Similarly, 48 (94.1%) out of 51 patients with a positive C-reactive protein value didn't survive in comparison to 31 (72%) out of 43 patients with a negative C-reactive protein. CONCLUSIONS: The presence of Type 2 Diabetes Mellitus and a positive C-reactive protein value were strongly associated with mortality. Patients with a Sequential organ failure assessment score of more than eight at intensive care unit admission and peak D-dimer level of more than or equal to two during intensive care unit stay didn't show significant association with mortality. These findings need further exploration through larger prospective studies.

Superior mesenteric artery (SMA) syndrome, though rare, should be considered in patients with duodenal obstruction with no other causes. History of recent weight loss and imaging modalities help in the diagnosis. Conservative management can be tried before going for surgery.
RESUMEN
Nitrobenzene can cause life threatening methaemoglobinemia. Its management includes the use of intravenous methylene blue to reduce the iron moiety from its ferric to ferrous state. Due to unavailability of intravenous preparation, enteral methylene blue was used in our case. This case report is to highlight that even oral preparations can be successfully used in a resource limited setting where often intravenous preparations are unavailable.
RESUMEN
Colonoscopy is considered a gold standard tool for the diagnostic evaluation of colorectal diseases. Bowel preparation, a pre-requisite for colonoscopy, usually involves ingestion of purgatives for the cleansing of the bowel so that visualization is not obscured during the procedure. Commonly used preparations are sodium phosphate-based solutions, sodium picosulphate and polyethylene glycol. The use of such preparations is associated with electrolyte disturbances, commonly hyponatremia. Hyponatremia is usually seen with sodium phosphate based solutions and is rare with polyethylene glycol. Symptomatic hyponatremia, however, is rare following bowel preparation and is attributable to other factors as well, such as the age of patient, non-osmotic release of antidiuretic hormone and the procedure itself. In this report, we discuss a case of severe symptomatic hyponatremia observed in a 71-year-old gentleman who underwent polyethylene glycol based bowel preparation for colonoscopy.

INTRODUCTION: Brachial plexus blocks are frequently practiced and safe mode of anaesthsia. Although minor complications may occur, major complications are a rarity. However, we report a rare case of prolonged supraclavicular brachial plexus block which required almost 4 months to recover without a perceivable cause. CASE PRESENTATION: A 22-year-old gentleman posted for open reduction and internal fixation of both forearm bones was administered an ultrasound-guided supraclavicular brachial plexus block. The intra-operative period was uneventful. However, the block persisted for a very prolonged period of time. All perceivable causes were ruled out. A total of 19 weeks was required for the entire block to regress with no residual neurological deficits thereafter. CONCLUSION: Although peripheral neuropathies are known complications of peripheral nerve blocks, such a prolonged brachial plexus block is a rare event. The only plausible cause for the patient's condition could have been the prolonged drug effect; however, it has been rarely documented.
RESUMEN
PURPOSE: Studies have shown that lung-ultrasound may be superior to chest x-ray (CXR) in diagnosing ventilator-associated pneumonia (VAP). This study investigated whether the use of lung-ultrasound monitoring could detect VAP earlier and improve patient outcome. METHODS: This was a single-center diagnostic randomized controlled trial. In the control group, VAP was diagnosed using a combination of CXR and clinical findings. In the intervention group, VAP was diagnosed using a combination of lung-ultrasound and clinical findings. The primary outcome measured was ventilator free days (VFD). Secondary outcomes were ICU mortality, length of stay in ICU, change in Sequential Organ Failure Score at day 4 compared to day 0 (delta SOFA), antibiotic duration and ventilator days. RESULTS: We randomized intubated patients until 44 VAP diagnosis was made in each group. VFD was higher in the intervention group than in the control group (7.80+/- 9.7 days versus 3.7+/- 6.4 days, p = .044). There were no differences between the groups in terms of ICU mortality (p=.104), ICU length of stay, (p = .058), ventilator days, (p = .081), delta SOFA (p = .10) and antibiotic duration (p = .70). CONCLUSION: The use of lung-ultrasound monitoring for diagnosis of VAP improves patient outcome when compared to the standard diagnostic strategy that relies on CXR.

BACKGROUND: Arterial blood gas is required for extubation decision after spontaneous breathing trial in most of intensive care unit. This study was conducted to assess the influence of arterial blood gas for extubation after successful spontaneous breathing trial in intensive care unit patients planned for extubation. METHODS: It was prospective observation study conducted in all patients of age greater than eighteen year admitted in intensive care unit of tertiary care hospital for one year. It was done in 108 patients who were planned for extubation. Patients were assessed by intensivist clinically and decided whether a patient can be extubated on clinical grounds. Spontaneous breathing trial was done for 2 hours by t-piece in patients who met clinical and objective criteria. Arterial blood gas was done in all patients who successfully completed spontaneous breathing trial. Patients with successful spontaneous breathing trial, acceptable arterial blood gas were extubated. Independent Student's t test and paired t test was used for data analysis. RESULTS: Out of 108 patients who passed the spontaneous breathing trial, 96(88.88%) patients had acceptable arterial blood gas and were extubated and 12(11.11%) patients did not have acceptable arterial blood gas level and were chosen to have other mode of weaning. CONCLUSIONS: This study demonstrates that arterial blood gas level has changed decision for extubation after successful spontaneous breathing trial. Further, arterial blood gas might help in identification of patients who can undergo extubation failure when rapid shallow breathing index failed to predict outcome of extubation.

Peripheral route for administration of vasopressors is often opted due to resource limitations or as a rescue until central venous access is established. This, however, is not devoid of complications, the most common being extravasation and tissue injury. Phentolamine is the only drug approved for management of vasopressor extravasation; however, successful use of other agents has been reported. Here we report a case of peripheral extravasation of vasopressors, successfully managed with topical nitroglycerin in intensive care unit in Kathmandu. To our knowledge, this is the first report of such kind from Nepal.
