An Unusual Complication of Paracentesis

Paracentesis is an important and commonly performed procedure in patients with ascites. It is a safe procedure when carried out in the midline below the umbilicus, with a complication rate of less than 1%. We report an instance in which a large midline varix was entered during paracentesis. The utility of different imaging techniques in detecting such anomalies in the portal hypertensive patient with portal hypertension and ascites is discussed. The approach and management of this complication are outlined.     

Pulmonary Function Testing in Patients with Tracheostomies: Feasibility and Technical Considerations

Purpose

Pulmonary function testing (PFT) in patients with tracheostomies has been perceived as difficult to perform and clinically unreliable. We studied the feasibility, quality, repeatability and clinical significance of PFT.

Methods

Patients with tracheostomies that underwent PFT from January 1, 2010 to February 29, 2012 were identified. Clinical history and PFT data were reviewed retrospectively.

Results

Fifty patients (88% men) were identified. Forty-seven (94%) patients were able to perform PFT. Acceptable repeatability was obtained for FVC in 39 (83%) and for FEV1 in 41 (87%). Patients with tracheostomies showed difficulty in meeting ATS end-of-test criteria; only 9 (19%) met plateau criteria and 25 (53%) had exhalation times of greater than 6 s. Obstructive pattern was observed in 30 (64%) and restrictive pattern in 9 (19%). DLCO measurements were attempted in 43 patients and satisfactorily obtained in 34 (79%).

Conclusions

PFT can be performed with reliability in patients with tracheostomies, and they are useful for detecting and classifying types of lung dysfunction.

     

Bleomycin for orbital and peri-orbital veno-lymphatic malformations – A systematic review

BackgroundOrbital and peri-orbital venolymphatic malformations (VLM) are low flow vascular malformations. Intralesional bleomycin is now commonly being used to treat such malformations.ObjectiveThe purpose of this systematic review is to synthesize evidence on the safety and efficacy of bleomycin/pingyangmycin sclerotherapy for the treatment of orbital and peri-orbital VLM.MethodsWe searched Medline, Embase, Scopus and Cochrane database for studies reporting outcomes of bleomycin/pingyangmycin sclerotherapy for orbital and peri-orbital VLM between 1974 to April 5th, 2019. Nine retrospective cohort studies enrolling 132 patients were included. Two reviewers independently screened and extracted data and assessed the risk of bias. Predefined outcome measures were subjective and objective reduction of the lesion and associated complications.ResultsSubjective reduction of the lesions was seen in 96.2% of the studies. Objective reduction of the lesion and symptomatic improvement were reported in 91.6 and 95% of the studies respectively. Non responders were 9.0%. Minor adverse events were reported in 18.1% of the studies. Major complications like pulmonary toxicity or pulmonary fibrosis was not encountered in any of the included studies. Quality of evidence was generally low.ConclusionBleomycin/pingyangmycin sclerotherapy is very effective and relatively safe for the treatment of orbital and periorbital VLM and is not associated with any major side effects including pulmonary fibrosis.Limitations: The systematic review is limited mainly due to low quality of the included studies with retrospective design.     

Volvulus of the transverse colon

Volvulus of the transverse colon is rare. Sixty-six cases have been reported in the English medical literature, and three new cases are presented herein. The causative factors, classical clinical presentation, radiologic findings, and management have been addressed. It is believed that colonoscopy will have an increasing role in the diagnosis and treatment of this condition in the future.     

Acute cardiac injury is associated with adverse outcomes,including mortality in COVID-19 patients: A single-center experience

Objectives:To evaluate acute cardiac injury in COVID-19 patients and its association with adverse outcomes including mortality in the United Arab Emirates (UAE) population.Methods:A retrospective study conducted between February and June 2020 in Dubai, UAE, for all laboratory-confirmed Coronavirus disease-19 patients. Demographic, clinical, laboratory, radiological, and clinical outcomes were compared between patients with and without acute cardiac injury.Results:During the study period, 203 patients were included, of which, 44 (21.7%) had evidence of acute cardiac injury. Compared with patients without acute cardiac injury, patients with acute cardiac injury were: older, had more shortness of breath, diabetes, hypertension, and more bilateral airspace shadowing on admission chest radiography. These patients also had a higher neutrophil count, C-reactive protein, procalcitonin, ferritin, D-dimers and lactate dehydrogenase but lower lymphocyte count. Regarding outcomes, these patients had higher intensive care admissions; a higher rate of complications including acute kidney and liver injury, acidosis, septic shock, acute respiratory distress syndrome, needed more mechanical ventilation, and had a significantly higher risk of death.Conclusion:Acute cardiac injury is common among Coronavirus disease-19 patients. These patients present with higher comorbidities, have high inflammatory markers and have greater risk for in-hospital multi-organ damage, need for mechanical ventilation, and death. Prompt full assessment and intervention are recommended.
