The Sequential Organ Failure Assessment (SOFA) score is commonly used in the Intensive Care Unit (ICU) to evaluate, prognosticate and assess patients. Since its validation, the SOFA score has served in various settings, including medical, trauma, surgical, cardiac, and neurological ICUs. It has been a strong mortality predictor and literature over the years has documented the ability of the SOFA score to accurately distinguish survivors from non-survivors on admission. Over the years, multiple variations have been proposed to the SOFA score, which have led to the evolution of alternate validated scoring models replacing one or more components of the SOFA scoring system. Various SOFA based models have been used to evaluate specific clinical populations, such as patients with cardiac dysfunction, hepatic failure, renal failure, different races and public health illnesses, etc. This study is aimed to conduct a review of modifications in SOFA score in the past several years. We review the literature evaluating various modifications to the SOFA score such as modified SOFA, Modified SOFA, modified Cardiovascular SOFA, Extra-renal SOFA, Chronic Liver Failure SOFA, Mexican SOFA, quick SOFA, Lactic acid quick SOFA (LqSOFA), SOFA in hematological malignancies, SOFA with Richmond Agitation-Sedation scale and Pediatric SOFA. Various organ systems, their relevant scoring and the proposed modifications in each of these systems are presented in detail. There is a need to incorporate the most recent literature into the SOFA scoring system to make it more relevant and accurate in this rapidly evolving critical care environment. For future directions, we plan to put together most if not all updates in SOFA score and probably validate it in a large database a single institution and validate it in multisite data base.

Lazarus phenomenon refers to autoresuscitation of a patient declared dead after cessation of cardiopulmonary resuscitation (CPR). The Lazarus phenomenon is rarely encountered and pathophysiology is not very well understood, but physicians need to be aware of this phenomenon. It is prudent that a physician leading a CPR effort waits for some time and monitors the patient further using blood pressure and electrocardiogram before confirming that a patient is actually dead.

Amniotic fluid embolism (AFE) is a rare and life-threatening complication related to pregnancy. Early diagnosis and prompt intervention are important tools for the survival of the patient. Despite early intervention, mortality rate remains high. We present a case of a 19-year-old female who was admitted for labor induction and delivery. Her delivery course was complicated by meconium-stained amniotic fluid. The patient went into acute hypoxic respiratory failure (AHRF) and hemodynamic compromise within half an hour following delivery secondary to AFE. We hereby discuss the role of timely initiation of extra corporeal membrane oxygenation (ECMO) in a case of AFE which could have otherwise turned out to be fatal.

Aspergillosis is a wide spectrum of the disease process that is caused by the fungus Aspergillus. Endobronchial aspergilloma is a very rare type of aspergillosis which is not yet included in the classification of aspergillosis. Due to its rare nature and a limited number of cases, there are no current treatment guidelines. Here we present the case of a 57-year-old female with an endobronchial aspergilloma. The patient was started on intravenous voriconazole and subsequently discharged on oral voriconazole.

Diabetic ketoacidosis (DKA) is a complication seen in patients with both type 1 and type 2 diabetes. Due to its large, growing economic impact with associated morbidity, closer look at proper management is important. Factors involved in appropriate management involves fluid resuscitation, insulin regimen, and electrolyte replacement including types of fluid and insulin treatment. The caveat with generalized protocol is application to special populations such as renal or heart failure patients the sequelae of complications due to pathophysiology of the disease processes. This leads to complications and longer length of stay in the hospital, therefore, possibly increased cost and resource utilization during the hospitalization. This review takes a closer look at current guidelines of DKA management and resource utilization, the drawbacks of current management protocols and the cost associated with it. Therefore, a need for amendment to existing protocol or initiation of a newer guideline that properly manages DKA should incorporate special populations and appropriate regimen of fluid resuscitation, insulin therapy and electrolyte management.

Patient: Female, 35 Final Diagnosis: Acute fibrinous and organizing pneumonia Symptoms: Shortness of breath Medication: — Clinical Procedure: Video assisted thoracoscopic lung biopsy Specialty: Pulmonology Objective: Unknown ethiology Background: Acute fibrinous organizing pneumonia (AFOP) is a rare condition of the lung that is associated with acute lung injury, and has a poor prognosis. AFOP is characterized histologically by intra-alveolar fibrin. AFOP has been described to be associated with lung infections, connective tissue disorders, drugs, toxic environmental exposure, and in lung transplantation. However, most cases of AFOP remain idiopathic, and because the condition can present with a wide variety of clinical manifestations, open lung biopsy or video-assisted thoracoscopic (VAT) lung biopsy is necessary for the diagnosis. Currently, treatments for AFOP remain under investigation. Case Report: A 35-year-old woman presented with a cough and dyspnea, and was initially diagnosed to have pneumonia. Due to the progression of her symptoms and increasing respiratory failure she underwent video-assisted thoracoscopic (VAT) biopsy and was diagnosed with AFOP, 19 days following hospital admission. She was treated with mechanical ventilation, intravenous steroids, and cyclophosphamide. She required tracheostomy after 14 days of mechanical ventilation and died two weeks later. Conclusions: AFOP is an uncommon clinical condition, with a poor prognosis, which often has a delay in diagnosis. Some patients benefit from steroids and immunosuppressive therapy. Currently, new treatments for AFOP are under investigation.

Mycobacterium terrae infection can cause progressive debilitating disease. A case of a 63-year-old man with localized pulmonary infection characterized by extensive, thick-walled cavitary lesions is presented. A pneumonectomy was considered as definitive treatment, but the patient would not have tolerated the procedure given his severe deconditioning. Instead, he was placed on lifelong antibiotic treatment, but he continued to deteriorate and passed away. The slow-growing microorganism, Mycobacterium terrae, was isolated from bronchoalveolar lavage cultures seven weeks after specimen collection, five and a half weeks after the patient’s death. Clinical, microbiological and therapeutic data from this case and 16 other pulmonary cases from the literature are reviewed. Increased awareness of this microorganism will allow clinicians to consider Mycobacterium terrae in their differential diagnosis when dealing with nontuberculous mycobacteria infections.

Pulmonary nodules have a broad differential diagnosis with primary lung cancer, lung metastases, benign tumors, carcinoid tumors, and infectious granulomas as their common cause. While relatively rare, pulmonary lymphoproliferative disorders such as primary pulmonary lymphomas, primary pulmonary plasmacytomas, secondary lymphomas involving the lung, multiple myeloma involving the lung, leukemias involving the lung should be considered in these patients presenting with lung nodules. Primary pulmonary non-Hodgkin’s lymphoma (NHL) is an extremely rare lung tumor accounting for 0.4% of all lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphoma accounts for about 70%-90% of all primary pulmonary lymphomas, constituting less than 0.5% of all the lung neoplasms. Though it usually remains localized, it is a clonal B-cell neoplasm with a potential for systematic spread and transformation to an aggressive B-cell lymphoma. We hereby discuss the case of a 66-year-old woman with primary pulmonary MALT lymphoma.

Sarcoidosis is a systemic granulomatous disease of unknown etiology characterized by presence of noncaseating granulomas in the involved organs. The pulmonary interstitium is most commonly affected but extrapulmonary involvement can occur in almost any other organ system. Such an involvement can occur with or without the presence of pulmonary involvement, but isolated extrapulmonary involvement has been noted only in around 10% of cases. Isolated splenomegaly is very rare and an uncommon presentation of sarcoidosis. It is clinically challenging because of the extensive differential diagnosis. Among the many considerations are hematologic malignancies, primary splenic or metastatic tumors, infiltrative disorders, inflammatory disorders, and infections. We hereby discuss an interesting case of a 40-year-old female with isolated splenic sarcoidosis.

A 44-year-old woman was brought to the ED from John F. Kennedy International Airport. The patient was returning with her son from a 3-month visit to Bangladesh. Her journey started with a 4-h flight from Dhaka, Bangladesh to Dubai, United Arab Emirates. She consumed 240 mL of whiskey during the flight. This was followed by a 14-h flight from Dubai to New York. According to the patient's son, she did not consume any alcohol during the second flight. The patient was in her usual state of health with normal mentation throughout her journey. Upon landing, she started complaining of shortness of breath. After disembarking, she was witnessed to have seizure-like activity with involuntary passage of urine, following which she collapsed. The patient was intubated by emergency medical services in the field.

Diffuse alveolar hemorrhage (DAH) is characterized by the presence of hemoptysis, anemia, and the presence of diffuse parenchymal infiltrates on imaging studies. Idiopathic pulmonary hemosiderosis (IPH) is an uncommon cause of diffuse alveolar hemorrhage (DAH) and is classically known to present in childhood. Adult-onset IPH is extremely rare. We report the case of a 48-year-old female patient who presented with hemoptysis and acute hypoxic respiratory failure, requiring intubation and mechanical ventilation. Imaging studies showed diffuse bilateral patchy infiltrates. Bronchoalveolar lavage (BAL) confirmed the diagnosis of DAH. Extensive workup including video-assisted thoracoscopic surgical lung biopsy (VATS) failed to reveal any vasculitis, infectious, immunological or connective tissue disorder, as the underlying cause for DAH. The patient was successfully treated with high-dose steroid therapy.

Introduction Little is known about the presence of patent foramen ovale in idiopathic pulmonary arterial hypertension. While there is suspected worsening of hypoxemia confounding assessment and management of pulmonary hypertension, as well as possible increased morbidity from paradoxical emboli, there may be theoretical relief of worsening right-sided pressures by the same mechanism of right-to-left shunting. Methods Retrospective review of consecutive patients diagnosed with idiopathic pulmonary arterial hypertension (WHO Group 1) via right heart catheterization, from 1998 to 2010. All patients also underwent a four chamber transthoracic echocardiogram with agitated saline contrast for the evaluation of patent foramen ovale. Primary clinical data was collected and compared between patients with and without patent foramen ovale along with univariable and multivariable predictors of long term survival. Results One hundred and fifty five patients were included in the study, 42 with patent foramen ovale (27%). Patients with patent foramen ovale were younger at pulmonary arterial hypertension diagnosis and trended towards higher right ventricular systolic pressures on echocardiography and mean pulmonary arterial pressures by right heart catheterization. Predictors of mortality included age, diffusing capacity for carbon monoxide, and severe hypoxemia. Only diffusing capacity and age were predictive of mortality after adjustment for a priori covariables. Conclusion Patent foramen ovale is seen in a quarter of patients with idiopathic pulmonary arterial hypertension and associated with increased prevalence of severe hypoxemia but had no effect on long term survival.

A 64-year-old previously healthy man presented with a 4-week history of vague right upper quadrant abdominal pain. Imaging studies revealed extensive portal, splenic, superior and inferior mesenteric vein thrombosis with mosaic perfusion and wedge-shaped areas of liver perfusion abnormalities. An extensive thrombophilia workup including tests for factor V Leiden, prothrombin G20210A, lupus anticoagulant, paroxysmal nocturnal haemoglobinuria, protein C and S, homocysteine and antinuclear antibody titres were all negative. Other laboratory testing revealed an elevated alkaline phosphatase (340 IU/L). Surgical exploration and catheter-directed thrombolysis were not felt to be feasible given the extensive clot burden. He was started on anticoagulation therapy. Over the next 10 days, he required intensive care unit admission due to progressive hepatic encephalopathy and fulminant liver failure. He continued to decline and eventually died of multiorgan failure. Autopsy revealed extensive, diffuse intrahepatic cholangiocarcinoma that had almost entirely replaced his normal liver parenchyma.

This article reviews the current literature for the purpose of developing a practical approach for the diagnosis and management of primary tracheal tumors.Because of nonspecific symptoms, tracheal tumors remain a diagnostic challenge. Currently available management strategies are not being optimally utilized due to lack of physician awareness and knowledge. The use of newer diagnostic modalities has increased diagnostic accuracy resulting in earlier detection in recent years. This review describes currently available diagnostic modalities along with relatively newer ones such as virtual bronchoscopy, anatomic Optical Coherence Tomography, spectroscopic techniques, and endobronchial ultrasonography. We will review and discuss management strategies including surgical options, adjuvant therapies, and interventional pulmonary techniques including their role in palliation.Early detection along with improved surgical and interventional pulmonology techniques has led to a decline in the death rates from tracheal cancer in recent years. However, further studies are required to define the role of chemotherapeutic agents, combination therapies, and novel techniques such as tracheal transplantation, in the management of primary tracheal tumors. More robust evidence-based studies are needed to provide evidence for clinical practice guidelines for the treatment of primary tracheal tumors.

Background Frailty is a condition of increased vulnerability to adverse health outcomes. Although frailty is an important prognostic factor for many conditions, the effect of frailty on mortality in lung transplantation is unknown. Our objective was to assess the association of frailty with survival after lung transplantation. Methods We performed a retrospective cohort analysis of all adult lung transplant recipients at our institution between 2002 and 2013. Frailty was assessed using the frailty deficit index, a validated instrument that assesses cumulative deficits for up to 32 impairments and measures the proportion of deficits present (with frailty defined as >0.25). We examined the association between frailty and survival, adjusting for age, sex, and bilateral (vs single) lung transplant using Cox proportional hazard regression models. Results Among 144 lung transplant patients, 102 (71%) completed self-reported questionnaires necessary to assess the frailty deficit index within 1 year before lung transplantation. Frail patients ( n = 46) had an increased risk of death, with an adjusted hazard ratio (HR) of 2.24 (95% confidence interval [CI], 1.22–4.19; p = 0.0089). Frailty was not associated with an increased duration of mechanical ventilation (median, 2 vs 2 days; p = 0.26), intensive care unit length of stay (median, 7.5 vs 6 days; p = 0.36) or hospital length of stay after transplantation (median, 14 vs 10.5 days; p = 0.26). Conclusions Pre-transplant frailty was independently associated with decreased survival after lung transplantation. Pre-transplant frailty may represent an important area for intervention to improve candidate selection and lung transplant outcomes.

Hepatoblastoma is a pediatric malignant tumor of the liver with very few cases reported in adults. There are no case reports on isolated metastatic lung involvement with hepatoblastoma in an adult who had been previously treated for the pediatric form of this disease. We report the case of a 27-year-old asymptomatic man who presented to the hospital after a motor vehicle accident. Imaging studies revealed bilateral lung masses. He had been treated for hepatoblastoma at the age of 10 years. Histopathologic examination of the lung biopsy revealed embryonal subtype of hepatoblastoma. Further imaging studies failed to reveal the presence of any concomitant liver lesions.

Klippel e Trenaunay e Weber syndrome (KTWS) is a congenital condition characterized by a triad of capillary malformations of the skin, soft tissue and bone hypertrophy resulting in limb enlargement, and abnormalities of arteriovenous and lymphatic systems of the affected limb. In this case, we present a patient with KTWS receiving chronic anticoagulation that had a massive pulmonary embolism and was successfully treated with thrombolytic therapy. The purpose of this case is to educate readers about this uncommon condition and to increase awareness, recognition and timely treatment of its most common complications, namely thrombosis and pulmonary embolism. © 2016 The Authors.
