A Case Report Describing Hemophilus parainfluenza Recovered From Pleural Effusion.

Hemophilus parainfluenza, a less common pathogen typically found in the oropharyngeal flora, has been associated with various clinical conditions. However, its role in pleural effusions remains scarcely documented. We present a unique case of a 42-year-old female with a history of asthma, hypertension, and obesity who presented with epigastric pain and a moderate right-sided pleural effusion. Hemophilus parainfluenza was isolated from the pleural fluid despite an atypical, asymptomatic presentation without pneumonia. Antibiotic treatment led to a positive response, highlighting the importance of recognizing Hemophilus parainfluenza as a potential causative agent in pleural effusion cases.

From Euphoria to Emergency: Exploring the Role of K2/Spice in Diffuse Alveolar Hemorrhage.

Marijuana or cannabis has been one of the most widely used recreational drugs, in the United States. However, a sinister counterpart has emerged in recent times: K2/Spice, a synthetic rendition of tetrahydrocannabinol (THC), capturing increasing popularity. Alarming reports have linked this synthetic compound to a multitude of life-threatening complications, ranging from acute kidney injury (AKI) from direct nephrotoxicity to cardiac arrest. Here we present the case of a 34-year-old man who presented with hemoptysis, later found to have diffuse alveolar hemorrhage (DAH) on the investigation after smoking K2/Spice successfully treated with a course of intravenous steroids. The case presented underscores the urgent need for increased awareness about the potential complications associated with synthetic compounds like K2/Spice, such as diffuse alveolar hemorrhage, and the importance of developing effective treatment strategies.

A Rare Case of Acute Pericarditis Due to SARS-CoV-2 Managed With Aspirin and Colchicine.

SARS-CoV-2 infection presents with predominant respiratory illness. Cardiac injury has been reported in patients with SARS-CoV-2 infection. The spectrum of cardiac involvement ranges from pericarditis to myocarditis. Acute pericarditis attributed to SARS-CoV-2 is rare. A 68-year-old male with co-morbid condition of hypertension and arthritis presented with chest tightness, cough and exertional shortness of breath for five days. He was tachycardic at the time of presentation and cardiac auscultation was positive for pericardial rub. His room air oxygen saturation was 95%. Chest imaging studies revealed bilateral infiltrate. His electrocardiogram showed ST elevation with diffusely elevated J point in lead II, III, aVF and V4-V6. Echocardiogram was unrevealing for pericardial effusion and left ventricular ejection fraction was normal. Serial troponin level did not reveal a rising trend. The nasopharyngeal swab was positive for SARS-CoV-2 RNA. Nonsteroidal anti-inflammatory drugs (NSAIDs) use in SARS-CoV-2 positive patient is debatable. The patient had acute pericarditis due to SARS-CoV-2 and it was treated with high dose aspirin with colchicine. Acute pericarditis is a rare complication of SARS-CoV-2 infection and can be managed with aspirin and colchicine.

A Rare Case of Splenic Pneumocystis jirovecii in a HIV-Positive Patient.

INTRODUCTION: Human immunodeficiency virus (HIV) positive individuals with the CD4 count less than 200 cells/mm3 are at risk for opportunistic infections. Pneumocystis jirovecii, a fungal pathogen, is a common cause of opportunistic infections with predominantly pulmonary involvement. Disseminated P. jiroveciii infection presenting with hepatosplenic lesion is extremely rare. Case Summary. A 31-year-old male with HIV with and acquired immunodeficiency syndrome (AIDS) presented with diarrhea for 3 weeks. He had splenomegaly and inguinal lymphadenopathy on physical examination. Laboratory parameters revealed anemia and hypoalbuminemia, while stool studies for infectious etiology and fecal leucocyte were negative. Computed tomography (CT) of the chest and abdomen depicted consolidation of the lungs and a large splenic mass. He underwent fiberoptic bronchoscopy with transbronchial biopsy which was consistent with P. jirovecii pneumonia. He also had a ultrasound-guided core biopsy of the splenic mass which revealed necrotizing granulomas with Pneumocystis jirovecii infection on Grocott-Gomori's methenamine silver (GMS) stain and was initiated on treatment for P. jirovecii with sulfamethoxazole with trimethoprim. CONCLUSION: Malignancy and atypical infection are key differentials in patients presenting with hepatosplenic lesions. HIV positive patients are at increased risk of AIDS-related lymphoma. Tissue diagnosis is often required for further evaluation. Disseminated P. jirovecii presenting with splenic mass and liver lesion is extremely rare.

Advances in the Diagnosis of Venous Thromboembolism: A Literature Review.

The incidence of venous thromboembolism (VTE), including lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) is increasing. The increase in suspicion for VTE has lowered the threshold for performing imaging studies to confirm diagnosis of VTE. However, only 20% of suspected cases have a confirmed diagnosis of VTE. Development of pulmonary embolism rule-out criteria (PERC) and update in pre-test probability have changed the paradigm of ruling-out patient with low index of suspicion. The D-dimer test in conjunction to the pre-test probability has been utilized in VTE diagnosis. The age appropriate D-dimer cutoff and inclusion of YEARS algorithm (signs of the DVT, hemoptysis and whether PE is the likely diagnosis) for the D-dimer cutoff have been recent updates in the evaluation of suspected PE. Multi-detector computed tomography pulmonary angiography (CTPA) and compression ultrasound (CUS) are the preferred imaging modality to diagnose PE and DVT respectively. The VTE diagnostic algorithm do differ in pregnant individuals. The prerequisite of avoiding excessive radiation has recruited planar ventilation-perfusion (V/Q) scan as preferred in pregnant patients to evaluate for PE. The modification of CUS protocol with addition of the Valsalva maneuver should be performed while evaluating DVT in pregnant individual.

Nonsteroidal Anti-Inflammatory Drugs Impact on the Outcomes of Hospitalized Patients with Clostridium difficile Infection.

PURPOSE: Mouse model experiments have demonstrated an increased Clostridium difficile infection (CDI) severity with Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) use. We aim to evaluate the impact of NSAIDs in humans after a diagnosis of CDI on primary outcomes defined as I) all-cause mortality and II) toxic mega-colon attributable to CDI. PATIENTS AND METHODS: All hospitalized patients with a diagnosis of CDI were divided into two groups; those with NSAIDs administered up to 10 days after onset of CDI versus no NSAIDs use. The primary outcomes were analyzed between the groups, while controlling for severity of CDI. A logistic regression analysis was performed to identify the predictors of worse outcomes. RESULTS: NSAIDs were administered in 14% (n=80) of the 568 hospitalized visits for an average of 2.5 days after the CDI diagnosis. All-cause mortality was high in patients who did not receive NSAIDs as compared to those who did receive NSAIDs (16.6% vs 12.5%, p 0.354). Patients who were prescribed NSAIDs were more likely to have toxic mega-colon as compared to those who were not prescribed NSAIDs (2.5% vs 0.6%, p 0.094). Results were not statistically significant, even after controlling for CDI severity. Logistic regression analysis did not identify NSAIDs administration as a significant factor for all-cause mortality in CDI patients. CONCLUSION: This retrospective study results, contrary to mouse model, did not show association between NSAID use and CDI related mortality and toxic mega-colon. Shorter duration of NSAIDs use, younger people in study group, and timely CDI treatment may have resulted in contrasting results.

Tuberculosis septic shock, an elusive pathophysiology and hurdles in management: A case report and review of literature.

BACKGROUND: Tuberculosis (TB) is a rare etiology of the septic shock. Timely administration of the anti-microbial agents has shown mortality benefit. Prompt diagnosis and a high index of suspicion are crucial to the management. We present three cases of TBSS with poor outcome in the majority despite timely and susceptible antibiotic administration. CASE SUMMARY: Sixty-seven-year-old woman with latent TB presented with fever, cough, and shortness of breath. She was promptly diagnosed with active TB and started on the appropriate anti-microbial regimen; she had a worsening clinical course with septic shock and multi-organ failure after initiation of antibiotics. Thirty-three-year-old man immunocompromised with acquired immune deficiency syndrome presented with fever, anorexia and weight loss. He had no respiratory symptoms, and first chest X-ray was normal. He had enlarged liver, spleen and lymph nodes suspicious for lymphoma. Despite broad-spectrum antibiotics, he succumbed to refractory septic shock and multi-organ failure. It was shortly before his death that anti-TB antimicrobials were initiated based on pathology reports of bone marrow and lymph node biopsies. Forty-nine-year-old woman with asthma and latent TB admitted with cough and shortness of breath. Although Initial sputum analysis was negative, a subsequent broncho-alveolar lavage turned out to be positive for acid fast bacilli followed by initiation of susceptible ant-TB regimen. She had a downward spiral clinical course with shock, multi-organ failure and finally death. CONCLUSION: Worse outcome despite timely initiation of appropriate antibiotics raises suspicion of TB immune reconstitution as a possible pathogenesis for TB septic shock.

Frequent Sips of the Water for the Management of Gastroesophageal Reflux Induced Refractory Cough: A Case Report and Review of the Literature.

BACKGROUND: Chronic cough is often associated with gastroesophageal reflux disease (GERD). The role of gastroenterologist in the management of the chronic cough is to identify and manage GERD. Ineffective esophageal motility is often associated with GERD induced cough. Chronic cough is often refractory to medical and surgical management despite adequate acid control. Unresponsiveness warrants a thorough pulmonary evaluation. The pathophysiology of refractory cough in these patients is poorly understood, and hence management is often challenging. CASE PRESENTATION: A 75-year-old woman from Ghana was evaluated for GERD associated chronic cough. A 48-hour ambulatory pH study revealed acid exposure of 4.9% and high-resolution manometry showed decreased lower esophageal sphincter pressure, an inadequate response to medical and surgical management of GERD. Postfundoplication ambulatory pH testing demonstrated well-controlled acid reflux but her cough still persisted. Repeat manometry showed an ineffective motility disorder (IEM). Taking frequent sips of water eventually resolved her chronic cough. CONCLUSION: Frequent sips of water can be used in the management of the gastroesophageal reflux and ineffective motility induced cough. It results in increased esophageal clearance of acid, nonacid reflux, and ingested pharyngeal secretions, thus breaking the cycle of cough generated increased intra-abdominal pressure with reflux and more cough.

A Case of Linezolid Toxicity Presenting as a Sepsis Mimic.

Linezolid is an efficacious and well tolerated antimicrobial but can have serious adverse effects including myelo-suppression, serotonin syndrome, neuropathy, hypoglycemia, liver dysfunction, and lactic acidosis. The side effects are generally duration dependent; linezolid use is not recommended for more than 28 days. Case. A 59-year-old female presented with malaise, loss of appetite, and altered mentation. She had multiple medical comorbidities and required long-term anticoagulation with warfarin for venous thromboembolism. She had multiple medication allergies. Prior to admission, she was on linezolid for cellulitis of foot due to Methicillin-resistant Staphylococcus aureus (MRSA). On physical exam, she was drowsy and required endotracheal intubation for airway protection. Initial laboratory parameters showed lactic acidosis, thrombocytopenia, supra-therapeutic coagulation profile, low blood glucose, and transaminitis. Her altered mentation was due to hypoglycemia. The interaction with warfarin led to altered coagulation profile. She developed shock and vasopressors were initiated. Given her presentation, she was managed as severe sepsis. There were no active infectious foci attributing to decline of her clinical status. Linezolid was discontinued and she was managed with intravenous polymyxin B, aztreonam, and vancomycin. Her hemodynamic status improved within one day. She was extubated on Day 5 of her presentation. Her laboratory parameters showed gradual improvement over 12 days after discontinuation of linezolid. Retrospective evaluation revealed linezolid toxicity as possible cause of presentation. Linezolid toxicity can present as sepsis mimic and should be considered as a differential diagnosis while managing sepsis with other antimicrobial agents.

A case report of Legionella and Mycoplasma pneumonia: Co-incidence or co-infection?

RATIONALE: Concurrent or sequential coinfections of Legionella pneumophila and Mycoplasma pneumoniae have been reported in the past though infrequently. Distinguishing a true co-infection from cross reactivity is often challenging as the diagnosis is mostly dependent on serological testing. PATIENT CONCERNS: A 77-year-old male presented with worsening dyspnea, cough with yellow sputum, diarrhea and fever of 2-days duration. Patient had history of chronic obstructive pulmonary disease (COPD) on home oxygen, bronchiectasis, rheumatoid arthritis (on methotrexate and leflunomide), treated pulmonary tuberculosis and 30-pack-year smoking. Chest X-ray showed bilateral interstitial changes with left lower lobe infiltrate. On day 5, his urine antigen for L pneumophila serogroup 1 was reported positive. The following day his serum M pneumoniae IgM antibody titers were reported elevated at 6647 U/mL. Patient was started on antibiotics and placed on non-invasive positive pressure ventilation. DIAGNOSIS: The patient was diagnosed with possible Legionella and Mycoplasma co-infection. OUTCOMES: Sputum Mycoplasma polymerase chain reaction (PCR) and serum cold agglutinins were obtained on day 6 and later reported negative. He was treated with azithromycin for 10 days with clinical improvement. LESSONS: Serological testing alone is an indirect measure with poor sensitivity and specificity and has its own limitations. Urine antigen detection confirms L pneumophila serogroup 1 infection in a patient with suggestive symptoms. However, diagnosis of M pneumonia should be based on combination of tests including serology and PCR to confirm true co-infection.

Purulent Pericarditis: An Uncommon Presentation of a Common Organism.

BACKGROUND In the modern antibiotic era, Streptococcus agalactiae infection of the endocardium and pericardial space is a rare occurrence. However, once the disease spreads it can lead to life-threatening illness despite advances in diagnostic and treatment modalities, partly because the symptoms and signs associated with pericarditis are frequently missing, and due to the rarity of the disease, diagnosis is often overlooked. We report an extremely rare case of purulent pericarditis caused by Streptococcus agalactiae. CASE REPORT A 65-year-old diabetic woman presented with generalized weakness, high-grade fever, and altered mental status. There were no signs or symptoms suggestive of cardiac tamponade on presentation. A computerized tomography (CT) scan of the chest showed a small pericardial effusion. She was managed for diabetic ketoacidosis and sepsis. An electrocardiogram was significant for new-onset atrial fibrillation. Her clinical status deteriorated rapidly as she developed acute hypoxic respiratory failure and shock. A bedside echocardiogram showed large pericardial effusion around the right ventricle and right ventricular diastolic collapse. She developed cardiac arrest, and during resuscitation bedside pericardiocentesis was done with drainage of 15 cc of serosanguineous fluid. However, the patient could not be revived. Subsequently, blood cultures grew Streptococcus agalactiae a day after she died. On autopsy, she was found to have findings of infective endocarditis and purulent pericarditis. CONCLUSIONS A high index of clinical suspicion is crucial when acute pericarditis is suspected, for early diagnosis and for timely initiation of appropriate therapy with antibiotics and aggressive pericardial drainage to prevent fatal outcome.

Lung cancer metastasis to the gastrointestinal system: An enigmatic occurrence.

Adenocarcinoma of the lung infrequently metastasizes to the gastrointestinal tract. We report a rare case of a 65-year-old male with no respiratory symptoms diagnosed with adenocarcinoma of the lung by histopathological examination of metastatic sites which included an ulcer in the gastric body and a mass in the rectum. Metastatic disease also involved the liver as well. Patient was treated with systemic chemotherapy but unfortunately expired five months after the diagnosis was made.

Symptomatic Gallstones in the Young: Changing Trends of the Gallstone Disease-Related Hospitalization in the State of New York: 1996 - 2010.

BACKGROUND: The aim of the study was to evaluate if the gallstone-related hospitalizations in the young (< 20 years of age) have increased over time in both the Bronx County and New York State as a whole. METHODS: We retrospectively reviewed 15 years (1996 - 2010) of Statewide Planning and Research Cooperative System (SPARCS) data of New York State Department of Health. Patients with ICD-9 code diagnosis of 574 (cholelithiasis) among the first three discharge diagnoses were reviewed. RESULTS: Total number of all cause admissions to hospitals had increased from 2.44 million to 2.77 million (1996 - 2010). However, gallstone-related hospitalizations had decreased from 1.7% to 1.2%. It was noted that there was a 30% increment in the proportion of those below 20 years of age with gallstone disease requiring hospitalization over the same period. This young patient population contributed only 2.04% to all gallstone-related hospitalizations in 1996, whereas it had increased to 2.96% in 2010. This trend was more pronounced in women, Hispanics and in those who were residing in the Bronx County as compared to all other New York counties combined. CONCLUSION: The gallstone-related hospitalizations in the young (< 20 years of age) have increased over time in both the Bronx County and New York State as a whole. This could be due to increasing prevalence of risk factors such as obesity, physical inactivity, diabetes and early pregnancy.

Fulminant Hepatic Failure Secondary to Herpes Hepatitis in a Patient With Myasthenia Crisis: An Elusive Diagnosis.

Herpes hepatitis is a rare cause of fulminant hepatic failure contributing to less than 1% of all cases. It is most often seen in persons who are immunosuppressed and in pregnant women. The presentation is usually non-specific and rapidly progressive, thus making antemortem diagnosis of this condition rare. We present a patient who was on chronic immunosuppressive therapy for systemic lupus erythematosus and subsequently developed multi-organ failure with anicteric transaminitis as a result of disseminated herpes infection. The diagnosis was only made post-mortem. A confounding factor in this case was the fact that the patient underwent plasmapheresis, which skewed the interpretation of liver function tests in the setting of acute liver failure.

Failing phrenics: an obscure cause of exertional dyspnea: Case report and literature review.

INTRODUCTION: Idiopathic phrenic nerve palsy is a rare cause of exertional dyspnea. We present a case of a patient presenting with worsening dyspnea of an unknown etiology found to be related to bilateral phrenic nerve palsy. DISCUSSION: Forty-two-year-old man presented to our emergency department with exertional dyspnea, orthopnea, and a left lower lobe consolidation treated initially as bronchitis by his primary physician as an outpatient, then subsequently as pneumonia at another institution, with no improvement in symptomatology. After admission to our hospital, CT chest demonstrated only supradiaphragmatic atelectatic changes. Echocardiography was normal. Bronchoscopy was contemplated however the patient could not lie flat. A fluoroscopic sniff test demonstrated diaphragmatic dysfunction and pulmonary function tests revealed restrictive pulmonary disease with evidence of neuromuscular etiology. Nerve conduction studies confirmed bilateral phrenic neuropathy. He was referred to a specialized neuromuscular disease center where subsequent workup did not demonstrate any specific etiology. A sleep study confirmed sleep disordered breathing suggestive of diaphragmatic paralysis and he was discharged on bi-level positive pressure ventilation. CONCLUSION: This is a unique case of exertional dyspnea and orthopnea from diaphragmatic paresis caused by bilateral phrenic nerve palsy where the initial workup for pulmonary and cardiovascular etiologies was essentially unremarkable. Shortness of breath and orthopnea caused by phrenic neuropathy is a rare condition, yet has a variety of etiologies. Our case suggests a template to the diagnostic approach, management, and follow up of bilateral phrenic nerve palsy.

Rapidly reversible multiorgan failure after ingestion of "Molly" (pure 3,4-methylenedioxymethamphetamine): a case report.

INTRODUCTION: "Molly" is a street name for pure 3,4-methylenedioxymethamphetamine, an amphetamine derivative which acts by enhancing the release of neurotransmitters such as serotonin, dopamine and norepinephrine. This produces euphoria, increased sensory awareness and central stimulation that make it a popular club drug. Nevertheless, it is also associated with serious side effects. We report an unusual case of rapid multiorgan failure after ingestion of "Molly". Unlike previously described patterns of 3,4-methylenedioxymethamphetamine-related organ failure, our case does not appear to be related to hyperthermia, rhabdomyolysis or hyponatremia. CASE PRESENTATION: A 24-year-old Hispanic man presented to our hospital with an episode of seizure and subsequently developed acute kidney injury, respiratory failure requiring mechanical ventilation and congestive heart failure after ingestion of "Molly". He rapidly recovered with supportive care and was discharged home. CONCLUSIONS: The spectrum of complications associated with 3,4-methylenedioxymethamphetamine is wide and patient presentation may vary. Moreover, there appears to be multiple mechanisms involved in organ failure. Drug toxicity should be suspected while evaluating a patient with multisystem organ failure of unclear etiology. Treatment is generally supportive sometimes requiring mechanical ventilation and hemodialysis. Nevertheless, complete reversal of organ failure can be expected.

Unusual triad of obstructive sleep apnea, uncontrolled hypertension, and severe hypokalemia due to ectopic adrenocorticotropic secretion.

Ectopic adrenocorticotropic hormone secretion is responsible for 12% to 17% of all cases of the Cushing syndrome. One of the most commonly described causes of ectopic adrenocorticotropic hormone secretion is small cell carcinoma of the lung. A rare cause includes a functioning neuroendocrine tumor traditionally known as carcinoids that account for 5% of all mediastinal tumors. To our knowledge, all reported cases of mediastinal carcinoids are thymic in origin and only a minority of those is functional. We present a male patient with hypertension, obstructive sleep apnea, and acid-base disorder, in whom further investigation revealed an anterior mediastinal mass and Cushing syndrome.
