RESUMO
Fungi rarely cause infective endocarditis but when they do, they are often associated with poor outcomes. Candida tropicalis accounts for only 10% of Candida endocarditis cases. A case of a 30-year-old male with a history of intravenous drug abuse was reported to the emergency department in August, 2021 with right-sided leg pain and fever for 3 days. A trans-thoracic echocardiogram showed a vegetation on the aortic valve and a computed tomography angiogram showed complete nonopacification of the right-sided common iliac artery and the superficial femoral artery just distal to its branching of the right profunda femoris artery. An emergent right iliofemoral embolectomy was done. Candida tropicalis was isolated from tissue and blood cultures. The patient was successfully treated with aortic valve replacement and intravenous caspofungin. The other reported cases of Candida tropicalis were reviewed and findings were compared with those reported in patients with Candida albicans and Candida parapsilosis endocarditis.

BACKGROUND: COVID-19, a highly infectious respiratory disease, has been associated with a range of cardiovascular complications. One of the most commonly reported cardiovascular issues in COVID-19 patients is the development of arrhythmias. Among all types of arrhythmias, atrial fibrillation is the most frequently observed. Atrial fibrillation is characterized by an irregular and often rapid heartbeat, and it can be a serious and potentially life-threatening condition. OBJECTIVE: To investigate the incidence and association of new onset atrial fibrillation in COVID-19 hospitalized patients and its impact on survival. METHOD: A retrospective cross-sectional study that encompassed all patients, both positive and negative for COVID-19, who were consecutively admitted to the Aga Khan University Hospital in Karachi, a tertiary care facility, from June 2021 to December 2021. RESULTS: A total of 1,313 patients who met the inclusion criteria of our study were enrolled as participants. These patients were then stratified into two groups based on COVID-19 status: the study group (COVID-19 positive) comprised 626 (47.7%) patients and the control group (COVID-19 negative) consisted of 687 (52.3%) patients. The incidence of new-onset atrial fibrillation was 85 (13.6%) in COVID-19 positive compared to 43 (5.2%) in COVID-19 negative group. The study found a strong association between COVID-19 and new-onset atrial fibrillation in both univariate (unadjusted odd ratio 2.35 [95% CI, 1.60-3.45], p-value < 0.01) and a multiple-adjusted regression analysis (adjusted odd ratio 3.86 [95% CI, 2.31-6.44], p-value < 0.01). CONCLUSION: These findings highlight the importance of vigilant monitoring of cardiovascular complications in COVID-19 patients, especially those with pre-existing conditions that predispose them to the development of atrial fibrillation. The study underscores the need for prompt recognition and management of new onset atrial fibrillation in COVID-19 patients, as this may mitigate the risk of adverse outcomes and improve overall prognosis.

BACKGROUND: Acute pulmonary embolism (PE) is a critical medical emergency that necessitates prompt identification and intervention. Accurate prognostication of early mortality is vital for recognizing patients at elevated risk for unfavourable outcomes and administering suitable therapy. Machine learning (ML) algorithms hold promise for enhancing the precision of early mortality prediction in PE patients. OBJECTIVE: To devise an ML algorithm for early mortality prediction in PE patients by employing clinical and laboratory variables. METHODS: This study utilized diverse oversampling techniques to improve the performance of various machine learning models including ANN, SVM, DT, RF, and AdaBoost for early mortality prediction. Appropriate oversampling methods were chosen for each model based on algorithm characteristics and dataset properties. Predictor variables included four lab tests, eight physiological time series indicators, and two general descriptors. Evaluation used metrics like accuracy, F1_score, precision, recall, Area Under the Curve (AUC) and Receiver Operating Characteristic (ROC) curves, providing a comprehensive view of models' predictive abilities. RESULTS: The findings indicated that the RF model with random oversampling exhibited superior performance among the five models assessed, achieving elevated accuracy and precision alongside high recall for predicting the death class. The oversampling approaches effectively equalized the sample distribution among the classes and enhanced the models' performance. CONCLUSIONS: The suggested ML technique can efficiently prognosticate mortality in patients afflicted with acute PE. The RF model with random oversampling can aid healthcare professionals in making well-informed decisions regarding the treatment of patients with acute PE. The study underscores the significance of oversampling methods in managing imbalanced data and emphasizes the potential of ML algorithms in refining early mortality prediction for PE patients.

The clinical presentation of COVID-19 varies from being asymptomatic to developing acute respiratory distress syndrome and multi-organ dysfunction. The diffuse microvascular thrombi in multiple organs seen in the autopsy of COVID-19 patients are similar to that of thrombotic microangiopathy (TMA). TMA is characterised by thrombus formation in the microvasculature with laboratory findings of microangiopathic haemolytic anaemia (MAHA) and thrombocytopenia. A 49-year-old male presented to the Aga Khan University Hospital, Karachi. with fever, diarrhoea, altered level of consciousness, and a positive nasopharyngeal swab for SARS-CoV-2. He developed severe thrombocytopenia, MAHA with 5.8% schistocytes, and worsening renal function on the sixth day of admission. Diagnosis of thrombotic thrombocytopenic purpura (TTP) was established based on PLASMIC score, and he was successfully treated with intravenous (IV) Methylprednisolone, therapeutic plasma exchange and IV Rituximab. The case emphasises the need to keep TTP in the differential diagnosis when a patient with COVID-19 develops severe thrombocytopenia, acute renal failure, or impaired level of consciousness, since prompt diagnosis and treatment is necessary to gain favourable outcome.

OBJECTIVE: To develop and apply a simple criterion for transfer of patients from intermediate care to general care. METHODS: The prospective study was conducted in the intermediate care units of Aga Khan University Hospital, Karachi, from July to December 2018. A discharge criterion for transfer of patients from intermediate care to general care was developed according to which patients with vital signs and Glasgow Coma Scale score within a preset range were considered stable enough for transfer from intermediate care to general care. After labelling the patients on the basis of the criterion, it was determined on the following day which patients remained stable enough for transfer to general care, and which patients became unstable. Data was analysed using SPSS 19. RESULTS: Of the 49 patients with mean age 63.0±16.9 years, 28(57.1%) were males. Overall, 43(87.7%) patients remained stable on the next day. Of them, 33(67.3%) patients were transferred out from intermediate care on the subsequent day, while 8(16.3%) were not transferred out due to primary physician's decision, 1(2%) due to heparin infusion, and 1(2%) due to family request. The condition of the remaining 6(12%) patients deteriorated. CONCLUSIONS: A simple discharge criterion is proposed for intermediate care solely based on clinical.

BACKGROUND: Neurological symptoms and complications of Coronavirus disease 2019 (COVID-19) were seldom discussed in the literature initially. Neurological symptoms such as headache, dizziness, anosmia, hypogeusia, and neuralgia are, however, now being reported commonly. Mononeuropathies are rare complications of COVID-19, with most cases associated with prolonged intensive care stay. CASE PRESENTATION: A 61-year-old gentleman with prior history of well-controlled diabetes and hypertension was recently treated for COVID-19 pneumonia with supplemental oxygen and positive pressure ventilation. He now presented with left-sided foot weakness two weeks after recovering from the viral illness. On examination he had normal bulk and tone and a power of 4/5 in proximal and distal muscles of bilateral lower limbs except for ankle dorsiflexion on the left which was 2/5. He also had absent ankle and knee reflexes bilaterally with bilateral flexor plantar reflexes. Since the patient had no back pain and the sensory system was normal, the lesion was localized to the peripheral nerves and a Nerve Conduction Studies and Electromyography (NCS/EMG) was done. NCS/EMG showed findings suggestive of axonal mononeuropathies. Relevant workup done to identify the cause of mononeuropathy was negative including infectious and autoimmune workup. Since diabetes was well-controlled and he had no intensive care stay his findings were presumed to be associated with resolving COVID-19 infection. The patient underwent aggressive daily physical therapy and has started to show improvement in symptoms. CONCLUSIONS: Complications such as mononeuropathies should be kept in mind in patients recovering from COVID-19 infection, since timely diagnosis can improve clinical outcomes in patients.
RESUMO
Background and Purpose: Influenza A and SARS-CoV-2 are risk factors for invasive pulmonary aspergillosis. Both influenza-associated pulmonary aspergillosis and COVID-19-associated pulmonary aspergillosis result in high mortality and poor clinical outcomes. No prospective study has so far compared the features, treatment, and outcomes of influenza-associated pulmonary aspergillosis and COVID-19-associated pulmonary aspergillosis within a similar time frame. Therefore, this study aimed to determine the frequency, risk factors, and outcomes of invasive pulmonary aspergillosis in critically ill patients with influenza, COVID-19, and community-acquired pneumonia. Materials and Methods: This prospective study included adult patients with pneumonia and was conducted at The Aga Khan University Hospital in Karachi, Pakistan. Patients were divided into three groups, including community-acquired pneumonia, influenza pneumonia, and COVID-19 pneumonia. The data collected included information on demographic characteristics, comorbidities, clinical features, laboratory results, treatment, and outcomes. Results: A total of 140 patients were included in this study. These included 35 (25%), 70 (50%), and 35 (25%) patients with community-acquired pneumonia, influenza pneumonia, and COVID-19 pneumonia, respectively. In addition, 20 (14.2%) patients were found to have invasive aspergillosis, of whom 10/35 (28.5%), 9/70 (12.8%), and 1/35 (2.8%) patients were in the COVID-19, influenza, and community-acquired pneumonia groups, respectively. Moreover, nine (90%) COVID-19-associated pulmonary aspergillosis patients required vasopressors, compared to three (33%) patients with influenza-associated pulmonary aspergillosis (P=0.020). In total, seven (70%) COVID-19-associated pulmonary aspergillosis patients required invasive mechanical ventilation compared to four (44%) influenza-associated pulmonary aspergillosis patients (P=0.37). The mean±SD length of hospital stay was highest in the COVID-19-associated pulmonary aspergillosis patients (18.3±7.28 days) compared to influenza-associated pulmonary aspergillosis patients (11.7±5.34 days) (P=0.036). The number of deaths in influenza-associated pulmonary aspergillosis and COVID-19-associated pulmonary aspergillosis patients was three (33.3%) and five (50%), respectively (P=0.526). Conclusion: A higher proportion of patients with COVID-19 developed invasive aspergillosis compared to those with influenza. Although the mortality rate in COVID-19-associated pulmonary aspergillosis was comparable to that in influenza-associated pulmonary aspergillosis patients, COVID-19-associated pulmonary aspergillosis patients had a significantly longer stay in the hospital.
RESUMO
We observed an unprecedented and consistent low performance of senior residents as compared with juniors in monthly examinations. This compelled us to evaluate systematically and compare the scores of senior residents with their junior colleagues. This retrospective observational study was conducted in April 2020 among internal medicine residents. Residents in first and second year of their training were labelled as junior residents. Residents in third or fourth year of their training were labelled as senior residents. Comparison of mean scores of each resident level was done separately both for monthly formative multiple-choice questions tests, and summative yearly end of term examinations. We discussed the possible reasons as well. There were 67 residents in year 2018 and 69 in 2019. There is no significant difference between scores of monthly examinations of years 2018 and 2019 among residents of each level. Rather, in March and December 2018, junior residents perform better than senior residents with p values of 0.01 and 0.04, respectively. In February and September 2019, senior residents performed better than junior residents with p value of 0.02. Similarly, there is no significant difference in scores of residents of each level in end-of-term examinations of years 2018 and 2019 with p values 0.18 and 0.25, respectively. Performance of senior residents in our residency programme in in-service examinations is relatively low as compared with their junior colleagues. There is a need to evaluate reasons for this relatively low performance of senior residents.

Background Atrial fibrillation (AF) is one of the most frequent arrhythmias in critically ill patients. Sepsis is a major cause of inpatient mortality and it has been associated with cardiac arrhythmias. The objective of this study was to study the outcome of atrial fibrillation in patients who are admitted with sepsis. Methods This is a prospective, single-center cohort study of patients admitted to the Medicine Department between June 1, 2019, and November 30, 2019. The inclusion criteria were adult patients with sepsis and septic shock. In this study, 113 patients were enrolled and outcomes were compared between the group that developed atrial fibrillation during the hospital stay and the group without atrial fibrillation. Results There were 57 (50.4%) patients with AF including 23 (20.4%) who also had a prior history. Total inpatient mortality was 42 (37.2%), of which 17 patients (40.5%) had AF. AF was not found to be associated with higher mortality or increased length of hospital stay (p-value 0.103 and 0.858, respectively). Conclusion AF was not found to be a cause of higher mortality in patients with sepsis or septic shock. There is a need for larger-scale studies to find out the causes of high inpatient mortality in sepsis and the need for local guidelines regarding the management of AF in critically ill patients.
RESUMO
Background Glycated hemoglobin (HbA1c) is a commonly used indicator of glycemic control in diabetes mellitus. Uncontrolled diabetes can lead to cardiovascular complications. Ischemic strokes are often complicated by hemorrhagic transformation, which is the conversion of an infarcted area into an area of hemorrhage. The purpose of this study is to determine the association of raised HbA1c levels with the occurrence of hemorrhagic transformation in ischemic stroke. Methods This is a prospective, single-center cohort study of patients admitted to the Neurology and Medicine wards between June 1 and November 30, 2019. Inclusion criteria included adult patients who were admitted with acute ischemic stroke and had been tested for HbA1c on presentation. There were 110 ischemic stroke patients enrolled in our database. An HbA1c level >53 mmol/mol was considered raised. A comparison was done between the group with raised HbA1c levels and the group with target levels of HbA1c for the occurrence of hemorrhagic transformation. Brain imaging was used to diagnose hemorrhagic transformation. Results Out of 110 study participants with ischemic stroke, 70 (63.6%) patients had a history of prior known diabetes. The mean HbA1c levels were 7.44 ± 1.79%. A total of 77% of diabetic patients had raised HbA1c levels (>7%). Hemorrhagic transformation was seen in 21 (19.1%) patients, of whom only 38% (n=8) had raised HbA1c levels. The association between raised HbA1c and hemorrhagic transformation was not found to be statistically significant (p = 0.225). Conclusion In this study of patients with ischemic stroke, raised HbA1c levels were not found to be associated with hemorrhagic transformation. There is a need for larger scale studies to find out the cause and mechanism of hemorrhagic transformation in ischemic stroke.
RESUMO
Background Blood groups are considered to have an impact on the occurrence and severity of coronavirus disease. While among Chinese and Caucasian, blood group O individuals were less and group A were more likely to have severe disease and mortality, data on South Asians aren't available. Objective This study aimed to find out the association of disease severity with blood group among coronavirus disease 2019 (COVID-19) patients. Materials and methodology Data were collected on a predesigned questionnaire containing details of patient demographics, medical comorbidities, clinical presentation, and laboratory parameters. Multiple logistic regression was used to determine the association of the blood group with the severity of coronavirus disease. Result Among the study participants, blood group B has the highest distribution (39.8%), followed by O (30.0), A (21.9%), and AB (8.1%). About three-fourths (69.9%) had mild to moderate disease while 30.0% had severe disease. Age, gender, hypertension, diabetes mellitus, and hemoglobin level were all associated with disease severity among COVID-19 patients in univariate analysis on P-value for selection (<0.25). The final model showed that the odds of disease severity is 3.62 times higher among males (OR: 3.62, 95% CI: 2.15-6.08) and 2.00 times higher among diabetic patients (OR: 2.00, 95% CI: 1.10-3.01) as compared to female and non-diabetic respectively. However, there was no significant association found between blood group and disease severity. Conclusion Blood groups don't have any role in forecasting the severity of coronavirus disease. However, the male gender and diabetics are prone to have severe disease.
RESUMO
BACKGROUND AND OBJECTIVES: The prevalence of diabetes mellitus worldwide was 171 million one and half decade ago, while the prediction is 366 million patients by 2030 and more than 640 million people by 2040. HbA1c value represents average blood glucose over the past 2-3 months and accounts for both pre-prandial and post-prandial blood glucose levels. A link between HbA1c and diabetic complications has been confirmed. In general, patients with controlled diabetes mellitus should have at least biannual testing, while patients with uncontrolled diabetes mellitus or unmet glycemic targets should be tested every three months. The objective was to see compliance of checking HbA1c in tertiary care hospital of a developing world. METHODS: This was a retrospective observational study done from 1st February 2019 to 31st March 2019 in the Department of Medicine and Surgery, The Aga Khan University Hospital, Karachi. All patients of age 18 years and above, admitted with a diagnosis of diabetes mellitus (DM)from 1st February 2019 to 31st March 2019 were included. If HbA1c was less than 7% the patients were labelled as having controlled DM, otherwise, uncontrolled DM. If HbA1c of patients with controlled DM was not checked in last six months and if HbA1c of patients with uncontrolled DM was not checked in last three months then it was labelled as non-compliance of checking HbA1c. RESULTS: Out of 1732 diabetic patients only 94 patients fulfilled inclusion criteria. Out of these 94 patients 43 (45.7%) were male. Mean HbA1c was 7.90% (1.4) and 69 (73.4%) patients had uncontrolled diabetes mellitus. Overall, the compliance of checking HbA1c was 58.5%. In uncontrolled diabetes mellitus patients, the compliance of checking HbA1c was 45% and in controlled diabetes mellitus patients the compliance was 96%. CONCLUSION: The compliance of checking HbA1c is inadequate in diabetic inpatients. The considerable prevalence of diabetes and the benefits of timely interventions in diagnosed patients to prevent complications suggest the need for a comprehensive awareness among the doctors for checking HbA1c.
RESUMO
A pneumonia outbreak of unknown aetiology emerged in Wuhan, China in December 2019. The causative organism was identified on 7th January 2020 as a novel coronavirus (nCoV or 2019-nCoV), later renamed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The resulting coronavirus disease (COVID-19) has infected over 88 million individuals, resulted in over 1.9 million deaths, and has led to an unprecedented impact on research activities worldwide. Extraordinary challenges have also been imposed on medical and surgical trainees following redeployment to full-time clinical duties. Moreover, the introduction of travel restrictions and strict lockdown measures have forced the closure of many institutions and laboratories working on research unrelated to the pandemic. The lockdown has similarly stifled supply chains and slowed research and development endeavours, whilst research charities have endured significant financial strains that have since reshaped the allocation and availability of funds. However, worldwide scientific adaptation to the COVID-19 pandemic has been observed through unprecedented levels of international collaboration alongside the uprise of remote telecommunication platforms. Although the long-term consequence of the COVID-19 pandemic on research and academic training is difficult to ascertain, the current crises will inevitably shape working and teaching patterns for years to come. To this end, we provide a comprehensive and critical evaluation of the impact of COVID-19 on scientific research and funding, as well as academic medical and surgical training.

The use of proton pump inhibitors (PPI) has been expanded inappropriately. PPI are among the most selling drugs in the world. There is growing evidence that PPI are associated with significant adverse effects along with undue financial burden. Inappropriate prescription of PPI is common in inpatients. The objective is to determine the frequency of inappropriate use of proton pump inhibitors for stress ulcer prophylaxis. This prospective observational study was conducted in the Department of Medicine of The Aga Khan University Hospital Karachi. 151 adult patients admitted in the hospital were included. All those patients who received PPI due to a condition mentioned by American Gastroenterology Association (AGA) as an indication for PPI, were labeled as PPI appropriately indicated. While those patients who received PPI without a condition mentioned by AGA as an indication for PPI, were labeled as PPI inappropriately indicated. Mean age was 57.2±18.2 years. Route of administration was oral in 110 (72.8%) and IV in 41 (27.2%) patients. Out of 151 patients, 100 (66.2%) patients were receiving PPI without any specific indication while 51 (33.8%) patients were receiving PPI with appropriate indications. Our study showed that inappropriate use of PPI is quite common among admitted patients.

Introduction The incidence of acute pyelonephritis (APN) in the diabetic population is comparatively higher and tends to be more complicated, with serious outcomes. Although complicated pyelonephritis (PN) needs hospital admission and intravenous antibiotics, the magnitude of hospital stay due to comorbidities is limited. This study's aim was to assess the impact of diabetes mellitus on length of hospital stay among patients with PN. Methods We did a retrospective data review of 520 randomly selected hospitalized patients of PN from March 2015 to December 2019 from a tertiary care center. Electronic medical records were used for identifying medical conditions through ICD-10 coding. Length of stay (LOS) was categorized as < five days and ≥ five days. Chi-squared tests were used to compare categorical parameters. Logistic regression models were used for multivariate analyses. Results The study included 520 patients with PN; 194 (37.3 %) men and 326 (62.7%) women. Overall, there were 353 (67.8 %) and 167 (32.1 %) patients with LOS < five and ≥ five days respectively. Most of the patients had lower urinary tract symptoms (90%); among them, the majority (92%) were discharged within five days. Likewise, half of the patients had diabetes (51.2); among them, 53% were discharged after five days. Older age (OR:1.7, 95%CI: 1.1 - 2.6), upper urinary tract symptoms (OR:1.6, 95%CI: 1.1 - 2.4), lower urinary tract symptoms (OR:1.9, 95%CI: 1.1 - 3.5), creatinine greater than 1.5 mg/dl (OR:1.6, 95% CI: 1.1 - 2.4) was positively associated with LOS ≥ 5 days after adjusting for other covariates. Diabetes mellitus was not found to be associated with LOS ≥ 5 days (OR: 0.9, 95%CI: 0.8 - 1.5). Conclusion In patients with acute PN, diabetes mellitus is not independently associated with prolonged hospital stay beyond five days.
RESUMO
BACKGROUND: Multisource feedback (MSF) is increasingly being used to assess trainee performance, with different assessor groups fulfilling a crucial role in utility of assessment data. However, in health professions education, research on assessor behaviors in MSF is limited. When assessing trainee performance in work settings, assessors use multidimensional conceptualizations of what constitutes effective performance, also called personal performance theories, to distinguish between various behaviors and sub competencies., This may not only explain assessor variability in Multi Source Feedback, but also result in differing acceptance (and use) of assessment data for developmental purposes. The purpose of this study was to explore performance theories of various assessor groups (residents and nurses) when assessing performance of residents. METHODS: A constructivist, inductive qualitative research approach and semi-structured interviews following MSF were used to explore performance theories of 14 nurses and 15 residents in the department of internal medicine at Aga Khan University (AKU). Inductive thematic content analysis of interview transcripts was used to identify and compare key dimensions in residents' and nurses' performance theories used in evaluation of resident performance. RESULTS: Seven major themes, reflecting key dimensions of assessors' performance theories, emerged from the qualitative data, namely; communication skills, patient care, accessibility, teamwork skills, responsibility, medical knowledge and professional attitude. There were considerable overlaps, but also meaningful differences in the performance theories of residents and the nurses, especially with respect to accessibility, teamwork and medical knowledge. CONCLUSION: Residents' and nurses' performance theories for assessing resident performance overlap to some extent, yet also show meaningful differences with respect to the performance dimensions they pay attention to or consider most important. In MSF, different assessor groups may therefore hold different performance theories, depending on their role. Our results further our understanding of assessor source effects in MSF. Implications of our findings are related to implementation of MSF, design of rating scales as well as interpretation and use of MSF data for selection and performance improvement.

COVID-19 pandemic has become a global concern. Cytokine release syndrome (CRS) complicates acute respiratory distress syndrome (ARDS) and causes multi-organ failure which can subsequently lead to mortality in COVID-19 patients. Tocilizumab, an interleukin-6 antagonist, has shown to salvage patients with cytokine release storm. In this study, we aim to evaluate therapeutic response of Tocilizumab in COVID-19 patients. A single-arm retrospective review of 40 patients with COVID-19, admitted to The Aga Khan University Hospital Karachi, from March 2020 to May 2020 was performed. Selection of patients for use of Tocilizumab was based on severity of disease, rapid clinical deterioration, presence of CRS and absence of any absolute contraindication to Tocilizumab. Improvement after Tocilizumab was defined as improvement in oxygen requirement and inflammatory parameters. Serum levels of inflammatory cytokines like C-reactive protein, ferritin, D-dimer and lactate dehydrogenase levels were monitored before and after administering Tocilizumab. Mean age was 62.4 years and 33 (82.5%) were male. 19 (47.5%) patients were critically sick, 18 (45%) were severely sick and 3 (7.5%) were moderately sick. 29 (77.5%) patients showed significant improvement in oxygen requirement, inflammatory parameters and chest x-rays, out of which 28 patients were discharged home. The mean duration between administration of Tocilizumab and overall improvement was 4.3 ± 3.2 days. Hence, Tocilizumab can be used as a possible treatment option in patients with COVID-19 induced CRS but needs monitoring for its adverse effects.

Tension pneumocephalus is a phenomenon in which air enters through dural injury in the brain and then expands and causes a mass effect. The injury can be due to any neurosurgical procedure, trauma, infection and/or neoplasm. A 63-year-old female known case of diabetes and hypertension had an elective procedure of right dacryocystorhinostomy present to the emergency department the very next day with a loss of consciousness. Urgent CT of the head showed air in the cranium (pneumocephalus). A radiological sign named "Mount Fuji" is classical for tension pneumocephalus. She was closely monitored and shows good clinical improvement allowing the neurosurgery team to avoid any intervention. The rationale to present this case is that to our knowledge, this is the first case in which tension pneumocephalus had occurred post-dacryocystorhinostomy. Due to the delicate region operated during eye surgeries, one should be more careful and vigilant.
RESUMO
Green coloured urine is atypical as it usually signifies the presence of an exogenous substance. Several substances in literature have been associated with green urine including propofol, biliverdin, metoclopramide, methylene blue, indigo blue, amitriptyline, methocarbamol, indomethacin, promethazine, cimetidine and food colourings. We present here a case of middleaged man who presented to our ER with altered mental status and green coloured urine with positive urine toxicology reports for benzodiazepine.
