Palliative Care and Chronic Obstructive Pulmonary Disease (COPD) Readmissions: A Narrative Review.

Despite all the advances in the treatment and management of chronic obstructive pulmonary disease (COPD), COPD readmissions remain a major challenge nationwide. Increasing evidence suggests that palliative care involvement with a holistic approach towards end-of-life care can significantly improve outcomes related to the quality of life and survival for late-stage cancers and chronic progressive illnesses like COPD, chronic heart failure, and end-stage renal disease. Some studies have attempted to evaluate an association between the involvement of palliative care and readmission reduction, the effect of which remains elusive, especially with regards to COPD readmissions. This review examined the existing literature to analyze the relationship between palliative care involvement for COPD patients and its effect on COPD readmissions.

Aggressive versus conservative fluid resuscitation in septic hemodialysis patients.

PURPOSE: Sepsis and bacterial infections are common in patients with end-stage renal disease (ESRD). We aimed to compare patients with ESRD on hemodialysis presenting to hospital with severe sepsis or septic shock who received <20 ml/kg of intravenous fluid to those who received ≥20 ml/kg during initial resuscitation. MATERIALS AND METHODS: We conducted a retrospective chart review of adult patients with ICD codes for discharge diagnosis of sepsis, severe sepsis, septic shock, ESRD, and hemodialysis admitted to our institution between 2015 and 2018. RESULTS: We present outcomes for a total of 104 patients - 51 patients in conservative group and 53 in aggressive group. The mean age was 69.5 ± 11.2 years and 71 ± 11.5 years in the conservative group and aggressive group, respectively. There was no significant difference in the rate of ICU admission, and ICU or hospital length of stay between the two groups. Complications such as volume overload, rate of intubation, and urgent dialysis were not found to be significantly different. CONCLUSION: We found that aggressive fluid resuscitation with ≥20 ml/kg may not be detrimental in the initial resuscitation of ESRD patients with SeS or SS. However, a clinical decision of volume responsiveness should be made on a case-by-case basis rather than a universal approach for fluid resuscitation in ESRD patients.

Trends and Outcomes of Gastrointestinal Bleeding Among Septic Shock Patients of the United States: A 10-Year Analysis of a Nationwide Inpatient Sample.

Introduction Gastrointestinal bleeding (GIB) complicating septic shock (SS) presents a therapeutic challenge in intensive care units. Large-scale data regarding utilization, length of stay, and cost outcomes of this association are lacking. Methods We queried the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample from 2003 to 2012, and identified all adult patients aged ≥18 years hospitalized for SS by the International Classification of Diseases, Ninth Revision (ICD-9) diagnostic code for SS and GIB. We compared the baseline characteristics and outcomes among patients with SS plus GIB to patients with SS without GIB. Results The weighted sample size from 2003 to 2012 was 119,684 admissions for SS. Among them, 6,571 (5.4%) patients were found to have a GIB. The mean age of the SS population with and without GIB was (mean/standard error of mean) [70.85 (0.43) vs. 67.43 (0.13) P < 0.001, respectively]. The incidence of GIB over the course of 10 years has remained stable; however, the mortality associated with GIB among SS patients is found to be declining especially from 2008 (59.2%) to 2012 (45.1%) (P < 0.01). Patients with SS and GIB compared to patients with SS and no GIB were found to have a longer length of stay [20.56 (0.61) vs. 15.76 (0.13) P < 0.001], higher mortality [54% vs. 45% P < 0.001], and higher admission costs in United States dollar ($) (mean/SEM) [$192,524.89 (7,378.20) vs. $142,688.55 (1,336.65) P < 0.001]. Univariate analysis demonstrated that comorbid conditions like peptic ulcer disease and cirrhosis had significant odds ratios {1.56 and 1.709, P = 0.016 and 0.046 respectively} for the occurrence of GIB with SS. Gastroesophageal reflux disease was found to be associated with a lower incidence of GIB [odds ratio: 0.57, P = 0.0008]. The cause of sepsis (pneumonia, urinary tract infection, or abdominal infections) was not a significant distinguishing factor for the incidence of GIB in SS. Conclusion GIB continues to affect the patients with SS admitted in intensive care units in the United States. We found an incidence of 5.4% of GIB in patients with SS, and it was associated with worse outcomes.

Lithium-induced Cardiotoxicity: A Rare Clinical Entity.

Lithium has been used effectively used in the management of mood disorders, such as bipolar disease, acute mania, and hypomania. As the therapeutic index is very narrow for lithium, it is important to monitor lithium levels periodically to avoid toxic effects. Common toxic effects include diarrhea, tremor, muscle weakness, ataxia, and myoclonus. Severe toxicity can present with seizures, coma, and death. Cardiotoxicity secondary to lithium is rarely reported in the medical literature and can range from dysrhythmias and cardiomyopathies to myocardial infarction. We describe an interesting case report of cardiac toxicity secondary to lithium in a bipolar patient managed conservatively in an intensive care setting.

Fluid resuscitation in patients with end-stage renal disease on hemodialysis presenting with severe sepsis or septic shock: A case control study.

Due to the potential risk of volume overload, physicians are hesitant to aggressively fluid-resuscitate septic patients with end-stage renal disease (ESRD) on hemodialysis (HD). Primary objective: To calculate the percentage of ESRD patients on HD (Case) who received ≥30 mL/Kg fluid resuscitation within the first 6 h compared to non-ESRD patients (Control) that presented with severe sepsis (SeS) or septic shock (SS). Secondary objectives: Effect of fluid resuscitation on intubation rate, need for urgent dialysis, hospital length of stay (LOS), intensive care unit (ICU) admission and LOS, need for vasopressors, and hospital mortality. Medical records of 715 patients with sepsis, SeS, SS, and ESRD were reviewed. We identified 104 Case and 111 Control patients. In the Case group, 23% of patients received ≥30 mL/Kg fluids compared to 60% in the Control group (p < 0.001). There was no significant difference in in-hospital mortality, need for urgent dialysis, intubation rates, ICU LOS, or hospital LOS between the two groups. Subgroup analysis between ESRD patients who received ≥30 mL/Kg (N = 80) vs those who received <30 mL/Kg (N = 24) showed no significant difference in any of the secondary outcomes. Compliance with 30 mL/Kg fluids was low for all patients but significantly lower for ESRD patients. Aggressive fluid resuscitation appears to be safe in ESRD patients.

Rhabdomyolysis in a Young Patient due to Hypothyroidism without Any Precipitating Factor.

Hypothyroidism is characterized by decreased hormone production, which results in various clinical manifestations in different organ systems. Muscular symptoms are common in patents with clinical hypothyroidism which includes muscle cramps, myalgia, and mild to moderate elevation of creatinine kinase less than five times the upper limit of normal. However, rhabdomyolysis due to hypothyroidism is rare and in most of the reported cases a precipitating factor has been found. We report a unique case of a 35-year-old male with no past medical history who presented with rhabdomyolysis due to newly diagnosed hypothyroidism without any precipitating factors and was treated successfully with intravenous fluids and levothyroxine.

Bronchial Obstruction Caused by a Dilated Pulmonary Artery.

Airway obstruction from an enlarged pulmonary artery (PA) is not a common occurrence. We present a rare case of respiratory failure secondary to right bronchus obstruction from a dilated right PA. A 54-year-old male with a known history of pulmonary hypertension (PH) and obstructive sleep apnea (OSA) presented with worsening dyspnea. He was found to have collapse of his right middle and lower lobes. Intubation was required for respiratory failure. To our knowledge, this is the first case to be reported in the literature where PH caused PA dilatation to such a degree as to cause bronchial obstruction and subsequent lobar collapse.

Cement pulmonary embolism after balloon kyphoplasty.

Osteoporotic vertebral fractures are common among the geriatric population and are managed by vertebral augmentation procedures. Pulmonary cement embolism is a relatively rare complication of these procedures and can range from mild, transient respiratory sequelae to a more severe pulmonary infarction. We discuss the case of a 75-year-old woman, identified with osteoporotic thoracolumbar vertebral fractures, found to have pulmonary cement embolism four days following multi-level balloon kyphoplasty. We attempt to highlight, pulmonary cement embolism as a potential complication following a vertebral augmentation procedure and that systematic pulmonary imaging after surgery may be helpful to facilitate its detection and further management.

Hepatocellular Carcinoma After Successful Treatment of Hepatitis C Virus with Ledipasvir/Sofosbuvir Presenting as Acute Pulmonary Tumor Embolism.

Hepatitis C virus (HCV)-induced cirrhosis is a major cause of hepatocellular carcinoma (HCC) worldwide. HCC is an aggressive malignancy in which tumor thrombus can invade portal vein, hepatic veins and inferior vena cava (IVC) in the later stages. Our case brings to attention, HCV patient population who might need long-term follow-up to ensure HCV clearance. Physicians should ensure appropriate follow-up after treatment of HCV and should emphasize on the ongoing screening for HCC in patients with cirrhosis or advanced fibrosis, regardless of antiviral treatment outcome.

Septic emboli of the lung due to Fusobacterium necrophorum, a case of Lemierre's syndrome.

Fusobacterium necrophorum plays a causal role in a rare and life-threatening condition, Lemierre's syndrome. It is characterized by infection involving the posterior compartment of the lateral pharyngeal space complicated by septic suppurative thrombophlebitis of the internal jugular vein with F. necrophorum bacteremia and metastatic abscesses, primarily to the lung and pulmonary septic emboli. Herein, we present a very rare case of oropharyngeal infection complicated by Lemierre's syndrome with characteristic septic emboli to the lungs presenting as sore throat in a previously healthy patient. A 23-year-old woman presented with sore throat and was found to be in sepsis and acute kidney injury. She was found to have septic emboli in lung and Streptococcus anginosus and F. necrophorum in blood. She was diagnosed with Lemierre's syndrome and successfully treated with antibiotics. Lemierre's syndrome should be included in the differential diagnosis in young patients who deteriorate in the setting of a sore throat. If the suspicion is high, throat swabs from young patients with nonstreptococcal group A tonsillitis should be cultured anaerobically on selective medium to detect the presence of F. necrophorum. While clinicians of the infectious disease team may be familiar with this condition other departments including internal medicine and critical care team may less so. Unless clinicians are aware of this syndrome, diagnosis and treatment can be delayed leading to higher morbidity and mortality.

Achromobacter xylosoxidans/denitrificans bacteremia and subsequent fatal Escherichia coli/Streptococcus anginosus pleural empyema.

Achromobacter xylosoxidans, a gram-negative bacillus with low virulence has rarely been reported to cause clinically significant infections. We report an unusual case of MDR Achromobacter xylosoxidans/denitrificans bacteremia from a peripherally inserted central catheter (PICC) and subsequent fatal pleural empyema due to MDR Escherichia coli and Streptococcus anginosus. A 44-year-old male presented to the hospital with chief complaints of chest tightness associated with a productive cough. He was found to have pleural empyema secondary to MDR E. coli and S. anginous. Three months prior to current presentation, he had a history of MDR A. xylosoxidans originating from a PICC. The patient expired even after appropriate management. Thoracic empyema continues to cause significant morbidity and mortality despite the improvement of antimicrobial therapy and the existence of multiple options for drainage of the infected pleural space. The bacteriology of thoracic empyema has been changing since the introduction of antibiotics. Typical antibiotics used to treat these MDR pathogens have become obsolete. Therefore, physicians should be aggressive in their diagnostic approach to pleural empyema, since the isolation of MDR aerobic gram-negative bacilli or multiple pathogens from the pleural fluid is associated with a poor prognosis and indicates a need for more aggressive antimicrobial chemotherapy. Also, the association of indwelling medical devices and MDR Achromobacter bacteremia should be known.

Giant cell carcinoma of the lung successfully treated with surgical resection and adjuvant vinorelbine and cisplatin.

Giant Cell Carcinoma of the lung, a subtype of Sarcomatoid lung cancer is a poorly differentiated Non-Small-Cell Lung Cancer. GCCL has exceptionally aggressive characteristics, and its prognosis is much poorer than any other NSCLCs. Herein, we present a rare case of Giant Cell Carcinoma of lung treated successfully with surgical resection and adjuvant vinorelbine and cisplatin. A 48-year-old African American man with a history of smoking and chronic obstructive pulmonary disease was admitted to the hospital for chief complaints of shortness of breath. He was found to have a 3.5 cm × 3.3 cm x 2.8 cm cavitary right upper lobe mass which turned out to be poorly differentiated Giant Cell Carcinoma with extensive necrosis and deemed similar to stage 1b non-small cell lung cancer. He was successfully treated with right upper lobectomy and adjuvant chemotherapy with vinorelbine and cisplatin. He was followed for seven years with no evidence of recurrent disease. Giant Cell Carcinoma's existing literature is limited, and hence our case is reportable. Our case is unique because of the better outcome which we believe might be the result of early detection and treatment with surgical resection along with adjuvant chemotherapy. More studies are needed to deeply understand the need for adjuvant chemotherapy in stage 1 b GCCL, and proper guidelines are required for the indications of adjuvant chemotherapy in Stage 1b GCCL.

Actinomyces viscosus causing disseminated disease in a patient on methotrexate.

Actinomycosis is an uncommon infectious disease caused predominantly by Actinomyces israelii. Actinomycosis usually involves the cervicofacial, thoracic, abdominal, and pelvic region, dissemination is uncommon. Actinomyces viscosus are commensal organisms that make up the normal flora of the oropharynx of humans and has rarely been reported to cause disease. Here, we report a unique case of disseminated actinomycosis with lung and brain lesions caused by Actinomyces viscosus resembling lung cancer with metastasis in a 74 year old male. Cultures from skin lesions confirmed A. viscosus. Although the patient was immunocompromised, antibiotic treatment with a penicillin-based regimen was effective.

Pulmonary Cavitary Disease Secondary to Mycobacterium xenopi Complicated by Respiratory Failure.

Non-tuberculous mycobacteria (NTM) are a significant cause of pulmonary infection worldwide and can be clinically challenging. Mycobacterium xenopi (M. xenopi) has low pathogenicity and usually requires either host immune impairment, as in the case of a human immunodeficiency virus infection, or a structural lung disease to cause a clinical disease. Comorbidities have an essential role in M. xenopi occurrence. Herein, we present a rare case of pulmonary cavitary disease caused by M. xenopi complicated by respiratory failure and superinfection in a patient with a chronic obstructive pulmonary disease. An 81-year-old woman presented to the hospital with the chief concerns of shortness of breath and productive cough lasting a few weeks before presentation. A computed tomography scan of the chest showed a right upper lobe, thick-walled, cavitary lesion measuring 2.1 cm x 4.3 cm x 3.1 cm with associated bronchiectasis and pleural parenchymal scarring. One year ago, the patient underwent bronchoscopy for a right upper lobe cavitary lesion, which revealed M. xenopi on bronchoalveolar lavage culture. During the current admission, she was started on rifampin, isoniazid, ethambutol, and clarithromycin because the M. xenopi was clinically significant and fulfilled the American Thoracic Society diagnostic criteria for NTM lung disease. A diagnosis of NTM pulmonary disease does not necessarily suggest that treatment is required. The distinction between colonization and illness may be difficult upon the isolation of M. xenopi. A patient-centered approach is essential given that M. xenopi is often considered a commensal pathogen. When treatment is required, a multidrug approach with an individualized, optimal duration of therapy should be considered.
