Secondary pyomyositis complicated by septic shock and sepsis-induced cardiomyopathy causing a massive erector spinae abscess in a patient after trigger point injection

Abstract

Trigger point injection is a common pain control method widely practiced around the world.

We report the case of a 53-year-old female who presented with lumbago and septic shock complicated with sepsis-induced cardiomyopathy three days after receiving a trigger point injection. She responded to sepsis treatment and empiric antibiotics but later required extensive drainage and debridement after a follow-up CT scan revealed a massive abscess above the fascia of erector spinae spanning from the level of the 1st thoracic spine to the 5th lumbar spine. With extensive surgical drainage and effective antimicrobial treatment, the patient recovered fully and was discharged without any sequelae.

Post-surgical right coronary artery injury secondary to tricuspid valve repair

Abstract

Injury to the right coronary artery (RCA) is a rare complication of tricuspid annuloplasty. We report a 64-year-old woman with history of valvular heart disease that was admitted for decompensated right heart failure. The patient underwent aortic valve replacement and tricuspid annuloplasty. Shortly after tricuspid annuloplasty the patient developed right ventricular (RV) infarction with hemodynamic compromise. The coronary angiogram shows subtotal occlusion at the mid segment of right coronary artery probably due to stitch of the tricuspid ring. The RCA has successfully been revascularized by percutaneous coronary angioplasty with bare metal stent, however the patient got into multi-organs failure syndrome and died at day 15 postoperatively.

Late pacemaker perforation of the right ventricle. A case report and review of diagnosis and management

Abstract

Objectives: Pacemaker incidence and prevalence are on the rise over the last decade especially in the elderly population. Though complications are rare, most reported literature is about early pacemaker complication. Late complications are also reported, but mostly regarding malfunction or infections. Very few case reports and series report late cardiac perforations which could be catastrophic. We report a case of late cardiac perforation diagnosed and treated in our institution to raise the awareness of this very serious complication.

Case summary: A 65-year-old male who had a single chamber right ventricular pacemaker inserted two months earlier for sick sinus syndrome, presented to the hospital with complaint of shortness of breath. Chest X-ray (CXR) revealed new large left sided pleural effusions. Computed tomography (CT) scan of the chest suggested migration of the pacemaker lead with perforation of the right ventricle associated with hemothorax with no pericardial effusions. A bedside echo confirmed the perforation and showed minimal pericardial effusions with no cardiac tamponade. Clinically patient was hemodynamically stable. He underwent open surgical repair and placement of epicardial pacer leads.

Conclusions: Clinicians should be aware of the early and late complications of pacemaker insertions and how to diagnose and treat them appropriately to avoid unnecessary morbidity or mortality.

Anticholinergic drug-induced benign unilateral anisocoria: common, but frequently overlooked side effect

Abstract

Sudden anisocoria have always been ominous signs among critically ill patients, which requires prompt attention. There are various causes of anisocoria, which call for comprehensive evaluation to rule out neurologic causes such as Adie’s pupil, uncal herniation, compression of third cranial nerve, meningeal irritation, and seizures as opposed to the pharmacological causes such as anticholinergic drugs, anesthesia, and recreational drugs versus causes such as migraine and trauma to the eye. We hereby report a case of a patient with unilateral anisocoria from dilated left pupil due to the nebulized ipratropium bromide, a cholinergic antagonist that resolved with discontinuation of the medication. The purpose of this case report is to emphasize the importance of thorough physical assessment, an early review of the medications, and the use of inexpensive diagnostic test to save time and avoid the expensive diagnostic study.

Case series: two cases of life threatening dynamic airway obstruction from thyroid mass

Abstract

We present 2 cases of dynamic airway obstruction with respiratory failure leading to cardiac arrest. Both have significant aetiology of cystic thyroid mass with sudden haemorrhagic changes leading to airway obstruction. We discuss the plausible pathophysiology leading to cardiopulmonary compromise where tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC) play a significant role. We note that this is under recognised and can be present as a life-threatening event. Recognition of these pathophysiology process facilitate surgical management of thyroid obstructive airway disease.

Respiratory arrest following CT guided selective cervical nerve root injection

CT guided cervical nerve root injection is performed for diagnostic purposes or to reduce inflammation and pain in cervical radiculopathy. Steroid and local anaesthetic are injected under CT guidance around the nerve root. This is performed as an outpatient procedure with most patients being able to be discharged 15-30 mins after the procedure. CT guidance allows the operator to see the best pathway for the needle whilst visualising structures such as the carotid and vertebral artery.

It is generally a safe procedure, with one recent study by RS Pobiel et al showing out of 802 fluoroscopy guided cervical nerve root blockades there were no major complications.

Use of levocarnitine as an alternative treatment for non-anticoagulant rodenticide poisoning

Abstract

The objective of this text is to inform and motivate further investigation about the use of levocarnitine as an alternative antidote in patients poisoned by non-anticoagulant rodenticides in a kind of retrospective study through the report of 3 serial cases presented in the Intensive Care Unit (ICU) of the General Hospital Zacatecas 'Luz González Cosío', in Zacatecas, Mexico. Two of them were intoxicated with zinc phosphide and one with sodium fluoracetate, all with similar signs and symptoms. In addition to having received vital support measures in the ICU, levocarnitine was administered intravenously, with remission of symptoms in the short term and hospital discharge without apparent sequelae. Therefore, it is appropriate to consider future research on the use of levocarnitine in this kind of patients, in addition to vital support measures.

Methaemoglobinaemia-induced oxygen desaturation complicating chest trauma

Case presentation

A 72-year-old man presented to the Emergency Department by ambulance following a rollover motor vehicle crash preceded by black-out symptoms. He had been suffering from dermatitis herpetiformis for the last six years and was being treated with dapsone 100 mg and a partially gluten-free diet. On admission he had a respiratory rate of 22, pulse oximetry saturations of 89% improving to 93% with 3 l/min via nasal prongs, a heart rate of 75 bpm, and a non-invasive blood pressure of 111/52. No life-threatening injuries were identified on primary or secondary survey. A trauma CT-series noted left sided rib fractures.

Propofol-induced macroglossia: a case report

Abstract

A 78-year-old lady, without prior exposure to propofol, was admitted to the hospital due to recurrent seizures, and respiratory arrest, which required intubation in order to secure her airway. Propofol was used as the initial sedative agent. Two weeks later she required again administration of propofol, time at which she developed acute macroglossia. This subsided after weaning off the propofol. When she was cared by another team and received for the third time propofol, she developed macroglossia again, and similarly subsided when propofol was weaned off. Allergic reactions to propofol are well documented. We believe that an allergic reaction occurred upon the second and third administration of propofol in our patient.

Malignant pericardial effusion presenting as a wheeze- case report

Abstract

Slow growing pericardial effusion is detected less commonly than acute pericardial tamponade. However, it is equally life threatening if it is more than 250 to 300 ml and can contribute to a similar picture of a fix cardiac output obstructive shock. We would like to report a case of malignant pericardial effusion that was detected in the ICU when the patient presented to the hospital with shortness of breath and generalized wheezes suggestive of respiratory failure from chronic obstructive lung disease (COPD).

Case report: central venous pressure-guided de-resuscitation in sepsis patients with fluid overload induced acute kidney injury

Abstract

Background: Aggressive fluid resuscitation is commonly administered in septic patients as recommended by Surviving Sepsis Campaign. However, positive fluid cumulative balance resulting in fluid overload is correlated with various complications such as acute kidney injury, acute respiratory distress and delayed wound healing.

Case report: This report presents four septic patients with fluid overload and acute kidney injury who underwent active de-resuscitation aiming central venous pressure between zero and two mmHg.

Discussion: In all patients, central venous pressure guided de-resuscitation was associated with systemic oxygenation improvement (arterial lactate dropped from 8.3 to 0.8 mmol/l, from 5.3 to 0.3 mmol/l, from 3.5 to 0.5 mmol/l, and from 3.3 to 0.7 mmol/l) and acute kidney injury resolution without hemodynamic instability and elevated lactate level. Negative cumulative balance is associated with a significant reduction of norepinephrine dose.

Conclusion: A de-resuscitation strategy based on the target of central venous pressure 0-2 mmHg is a safe and effective procedure that resulted in improvement in hemodynamics, serum lactate, renal function and also systemic oxygenation.

Status epilepticus caused by cerebral venous thrombosis in the puerperal period: case report and literature review

Abstract

Status epilepticus (SE) caused by cerebral venous thrombosis (CVT) is rare in pregnancy and puerperium, with few cases described in literature. Seizures in pregnancy are usually due to previous epilepsy or pregnancy related disease, such as eclampsia, posterior reversible encephalopathy syndrome (PRES), reversible cerebral vasoconstriction syndrome (RCVS), eclampsia and thrombotic thrombocytopenic purpura (TTP). Due to its high mortality, the SE and the underlying disease must be promptly managed. In this article, we present a case of SE in postpartum due to cerebral venous thrombosis and we reviewed the cases described on the topic.

Role of hemofilter with endotoxin adsorption capacity in management of septic shock

Abstract

We reported an adolescent male with acute lymphoblastic leukemia who developed septic shock due to Klebsiella pneumoniae. Continuous renal replacement therapy using a hemofilter with endotoxin adsorption capacity was used to remove endotoxin and cytokines. The promising result suggested that this technique may be applied as an adjuvant therapy for treatment of septic shock.

A 20-year-old woman with spinal cord injury without radiological abnormalities (SCIWORA)

Abstract

Spinal cord injury without radiological abnormalities (SCIWORA) has been defined as a direct trauma to the spinal cord, with no radiological or tomographic abnormalities, although there is a deficit, whether motor, sensory or both. To establish the final diagnosis, shock, obstetrical complications, penetrating trauma to the spine and congenital malformations should be excluded.

Factors contributing to the accuracy of initial screening values measured by noninvasive spectrophotometric hemoglobin monitoring in an Emergency Department

Abstract

Objective: Spectrophotometric hemoglobin (SpHb) monitoring is a new noninvasive technology for measuring hemoglobin (Hb). However, few studies have assessed the usefulness of the initial screening SpHb values, especially when measured in an Emergency Department. In this study, we examined the correlation between the initial screening SpHb values and laboratory-measured hemoglobin (Hb) concentrations.

Design: This was a retrospective, single center study.

Setting: Emergency Department in a University hospital.

Patients: 105 cases between February and July 2016.

Interventions: The correlation between SpHb and Hb was determined in univariate analysis. Multiple regression analysis was then performed with ΔHb (defined as the absolute difference between SpHb and Hb [|SpHb-Hb|]) as the dependent variable to identify factors associated with reduced accuracy of SpHb.

Results: The initial screening SpHb value was only moderately correlated with Hb in univariate analysis (r=0.736, p<0.001). In multiple regression analysis, male sex and diastolic blood pressure were significantly associated with ΔHb (p=0.003 and p=0.022, respectively).

Conclusions: The initial screening SpHb value was only moderately correlated with Hb. SpHb might affected by patient factors, including male sex and diastolic blood pressure.
