Early outcomes of abbreviated multi-fractionated brachytherapy schedule for cervix cancer during COVID-19 pandemic.

PURPOSE: Brachytherapy (BT) for cervix cancer was listed as a level I priority and reduced number of implants and multiple fractions were recommended during COVID-19 pandemic. We present early clinical outcome of this approach. METHODS AND MATERIALS: Patients treated with (chemo)radiotherapy and BT with single implant and multiple fractions BT were included. Treatment protocol included 3-5 fractions of 5-8.5 Gy with an aim to achieve point A dose of 70 Gy EQD210Gy (or HRCTV dose of >80 Gy EQD210Gy) in those undergoing intracavitary (IC) and HRCTV dose >85 Gy EQD2 10Gy in patients undergoing Intracavitary-Interstitial (IC/IS) whereas maintaining bladder (B2cc), rectum (R2cc), sigmoid (S 2cc) doses of 90, 75, and 75 Gy EQD23Gy. Time to event analysis was used to report oncological endpoints. Toxicity was reported using crude proportions. RESULTS: From April 2020 to March, 2021, 64 patients with stage IB2-IV received single implant and multi-fraction BT after external radiation of 45 Gy/25 fractions/5 weeks. Only 76.7% (n = 49) received concurrent chemotherapy. Median overall treatment time (OTT) was 56 days (38-131 days). Overall, 62.5% (n = 40) patients received IC and 37.5% (n = 24) received IC+IS. The median HRCTV was 34.7 cc (IQR 25-41). Median (IQR) point A dose, HRCTV D90, B2cc, R2cc, and S2cc for those undergoing IC was 74 Gy (71-78), 80 Gy (73-84), 86 Gy (82-89), 70 Gy (65-74), 65 Gy (59-73) respectively. For the IC+IS cohort, HRCTV D90, B2cc, R2cc, and S2cc was 84 Gy (78-89 Gy), 89 Gy (86-92), 70 Gy (67-74), 68 Gy (59-76). At a median follow-up of 16 months (5-27) the 2-year local control, pelvic control, cause specific and overall survival was 88%, 85.3%, 92.2%, and 81.3% respectively. Late gastrointestinal and genitourinary grade ≥III toxicities were 14% and 1.5% each. CONCLUSIONS: Abbreviated BT outcomes are encouraging for oncological outcomes despite delays in overall treatment time and omission of chemotherapy. Further mature follow up is needed.

COVID-19 and Cavitary Lesion in Lung.

The clinical manifestations of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are widespread, ranging from asymptomatic to critical illness with significant morbidity and mortality. It is widely known that individuals who have viral respiratory infections are more likely to develop bacterial infections. Throughout the pandemic, despite the fact that COVID-19 was thought to be the primary cause of millions of deaths, bacterial coinfections, superinfections, and other secondary complications played a significant role in the increased mortality rate. In our case, a 76-year-old male presented to the hospital complaining of shortness of air. Polymerase chain reaction (PCR) testing was positive for COVID-19 and cavitary lesions were discovered on imaging. Treatment was guided based on the results of bronchoscopy with bronchoalveolar lavage (BAL) cultures showing methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium gordonae. However, the case was later complicated by the development of a pulmonary embolism after anticoagulants were held due to new onset hemoptysis. Our case highlights the importance of considering bacterial coinfection in cavitary lung lesions, appropriate antimicrobial stewardship, and close follow-up for full recovery in COVID-19 infections.

Arcanobacterium haemolyticum bacteremia presenting as severe sepsis: A case report and review of the literature.

Objective: to describe a case of severe sepsis and complicated bacteremia caused by Arcanobacterium haemolyticum and review similar cases in the literature. Case summary: A 26-year-old gentleman with a history of epilepsy presented with symptoms of sore throat, productive cough, periumbilical abdominal pain, watery diarrhea, nausea and vomiting, subjective fevers along with progressive jaundice for seven days. The patient had acute fulminant liver failure, septic shock, and Multi-organ failure. He required vasopressors, underwent intubation, and had grown Arcanobacterium haemolyticum in the blood and Bronchoalveolar lavage samples. He developed a peritonsillar abscess and cavitary pneumonia and required chest tube drainage followed by thoracotomy for hemothorax. The patient improved on Ampicillin-Sulbactam treatment and was treated with a total antibiotic duration of 6 weeks. He fully improved on post-discharge follow-up. Discussion: Arcanobacterium haemolyticum is a Gram-positive (sometimes Gram variable), catalase-negative facultatively anaerobic, non-motile, non-spore-forming, and variably ß-hemolytic and is known to be a cause of pharyngitis and skin and soft tissue infections. Rarely A. Haemolyticum can be associated with severe systemic infections such as infective endocarditis, systemic abscesses, osteomyelitis, and septicemia. In previous literature reviews, the source of A. haemolyticum depended on the host, and pharyngeal and upper respiratory sources were likely to be associated with immunocompetent hosts. Conclusion: A. haemolyticum should be included in the differential diagnosis of bacterial pharyngitis complicated by severe systemic illness. Penicillins are the most commonly used antibiotics for treating A. haemolyticum bacteremia, and macrolides can be used for Penicillin's treatment failure.

Diagnostic and treatment dilemma during the coronavirus disease 2019 pandemic: a primary pulmonary lymphoma presenting as a cavitary mass in a patient with coronavirus disease 2019: a case report.

BACKGROUND: A radiological finding of a cavitary pulmonary lesion in a patient acutely infected with severe acute respiratory syndrome coronavirus-2 early during the coronavirus disease 2019 pandemic created a diagnostic and treatment dilemma, as invasive procedures with bronchoscopy and percutaneous needle lung biopsy posed an infection hazard to healthcare workers due to the associated risk of viral aerosolization. Available guidelines recommended delay of non-emergent procedures, but timely proceeding with those deemed urgent provided appropriate personal protective equipment and negative pressure isolation were available and exposure risk was not excessive. Thoughtful consideration by clinicians was required to avoid delay in diagnosis of a potential new malignancy and prevent unnecessary healthcare worker exposure to the virus. Additionally, acute severe acute respiratory syndrome coronavirus-2 infection in patients with malignancy complicated timing of oncologic treatment. CASE PRESENTATION: A 26-year-old otherwise healthy Caucasian male initially presented with an enlarging right upper lobe cavitary pulmonary lesion despite antimicrobial therapy. During his hospitalization and evaluation, the patient was found to be acutely infected with severe acute respiratory syndrome coronavirus-2 without hypoxia or viral pneumonia. Bronchoscopy was deemed too high risk for viral aerosolization and healthcare worker infection. He underwent computed-tomography-guided percutaneous needle biopsy of the lesion by interventional radiology while on mechanical ventilation after elective intubation by anesthesiology. Biopsy revealed classic Hodgkin lymphoma consistent with primary pulmonary Hodgkin lymphoma. After collaboration with oncology, his treatment with combined chemotherapy and immunotherapy was delayed for 3 weeks following diagnosis to allow for viral clearance. CONCLUSION: A careful multidisciplinary strategy is required to expeditiously diagnose and treat aggressive cancers of the respiratory tract in patients acutely infected with severe acute respiratory syndrome coronavirus-2 while observing practices to prevent healthcare worker infection during the ongoing coronavirus disease 2019 pandemic.

Unusual manifestation of COVID-19-associated pulmonary aspergillosis: A case report.

A young man, a recent coronavirus patient, was readmitted with hypoesthesia and dysarthria following a rapid deterioration of respiratory symptoms. The brain and lung CT scans revealed ischemia and cavitary lung lesions. Clinical suspicion for aspergillus leads to prompt treatment, confirmed by biopsy. Neurologic and pulmonary symptoms resolved ultimately.

Reactivation of Tuberculosis in the Setting of COVID-19 Infection.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2) was declared a pandemic by WHO in March 2020. The causative organism has since undergone a series of mutations. COVID-19 primarily being a respiratory illness causes pre-existing pulmonary diseases to show worse clinical outcomes. About one-third of the world's population is thought to be infected with latent Mycobacterium tuberculosis (MTB). Both previous and newly developed tuberculosis (TB) infection are risk factors for COVID-19 and are associated with poor outcomes. T lymphocytes play a pivotal role in defense against MTB and with evidence suggesting depletion of T lymphocytes in COVID-19, it can be postulated that COVID-19 can increase the risk of reactivation of latent TB.  Given that a large population around the globe is infected with latent tuberculosis, it is interesting to study and note cases where the virus leads to the reactivation of latent tuberculosis infection. Herein, we present a 76-year-old Brazilian male recently treated for COVID-19 pneumonia, presenting with new-onset cough and weakness diagnosed with latent MTB reactivation.

COVID-19-Induced Cavitary Lesion: A Rare Presentation.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in widespread infection with significant morbidity and mortality. Primarily involving the respiratory system, COVID-19 has also been known to cause systemic findings. Cavitary lesions in the setting of COVID-19 have been rarely reported in literature and the treatment and management of these lesions are poorly understood and defined. We present a case of a patient with a history of COVID-19 infection found to have cavitary lesions, eventually improving with supportive care. While our patient showed marked improvement with observation, more extensive studies and patient populations are needed to guide clinicians and cavitary lesion management in the setting of COVID-19.

Simultaneous Giant cavity pulmonary lesion and pneumothorax following COVID-19 pneumonia.

Cavitary lung formation with spontaneous pneumothorax has been rarely reported as a complication of COVID-19 pneumonia. We report a rare case of a 38 years-old male patient affected by COVID-19 pneumonia, exceptionally complicated by a simultaneous giant cavity in the right upper lung and a small right pneumothorax in the right hemithorax. Whilst pneumothorax emphysema, giant bullae and pneumothorax with alveolar rupture are known to potentially develop in COVID-19 patients as a result of high-flow O2 support, the exact origin of the giant lung cavitation in our patient could be not confirmed. Cavitary lesions - featured by high mortality rate - are reportedly associated with lung infarctions and can be the aftermaths of pulmonary embolism, a rather common sequela of COVID-19 pneumonia. Radiological imaging is critical to support clinical decision making in the management of COVID-19 pneumonia, since not only it can visualize and stage the disease, but it can also detect and monitor the eventual onset of complications over time, even following patient discharge from hospital.

Development of cavitary lung disease as a long-term complication of coronavirus disease 2019 in a young previously healthy patient: a case report.

BACKGROUND: Cavities are frequent manifestations of a wide variety of pathological processes involving the lung. There has been a growing body of evidence of coronavirus disease 2019 leading to a cavitary pulmonary disease. CASE PRESENTATION: A healthy 29-year-old Filipino male presented to the hospital a couple of months after convalescence from coronavirus disease 2019 with severe pleuritic chest pain, fever, chills, and shortness of breath, and was found to have a cavitary lung lesion on chest computed tomography. While conservative management alone failed to improve the patient's condition, he ultimately underwent left lung video-assisted thoracoscopic surgery decortication. Even though the surgical pathology revealed only necrosis with dense acute inflammation and granulation tissue with no microorganisms, he gradually improved with medical therapy adjunct with surgical therapy. CONCLUSION: Documented cases of cavitary lung disease secondary to coronavirus disease 2019 have been mostly reported in the acute or subacute phase of the infection. However, clinicians should recognize this entity as a late complication of coronavirus disease 2019, even in previously healthy individuals.

A Coronavirus Disease 2019 (COVID-19) Mystery: Persistent Fevers and Leukocytosis in a Patient With Severe COVID-19.

Short-course glucocorticosteroids are being used and tocilizumab (TCZ) had been used to treat patients with severe coronavirus disease 2019 (COVID-19) disease. These agents, when administered individually, have been associated with tuberculosis (TB) during chronic use. We report a case of TB in a 44-year-old male with diabetes and severe COVID-19 who received high-dose short-course glucocorticosteroids and a single dose of TCZ. The clinical presentation was atypical with unresolving fevers and leukocytosis, progressive lower lobe cavities, and hilar adenopathy. Delayed diagnosis led to prolonged hospitalization and extensive antibiotic use.

Cavitary lung lesions and pneumothorax in a healthy patient with active coronavirus-19 (COVID-19) viral pneumonia.

Severe respiratory sequelae drive morbidity-associated with coronavirus 2019 (COVID-19) disease. We report a case of COVID-19 pneumonia complicated by cavitary lesions and pneumothorax in a young healthy male. Pneumothorax management with catheter thoracostomy and rapid resolution of the cavitary lesions are described. An extensive work-up for other causes a cavitation was negative and the temporal correlation of the cavities with COVID-19 infection plus their rapid resolution suggest a direct relationship. We propose a mechanism for cavitation secondary to microangiopathy, a cause of cavitation in the vasculitides and a known feature of COVID-19.

The Coincidence of 2 Epidemics, Coccidioidomycosis and SARS-CoV-2: A Case Report.

In the middle of a pandemic, patients with cough and fever are thought to have SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2). It should be remembered that in the desert southwest of the United States, we have an ongoing epidemic of coccidioidomycosis (CM). There are additionally many other respiratory illnesses that could be confused with CoV-2 or overlooked. This is a case report of CoV-2 engrafted on chronic cavitary pulmonary CM. In a time where the coronavirus pandemic is becoming rampant, we demonstrate the case of a coinfection with cavitary pulmonary CM. In this case, the importance of detection of the coronavirus and treatment of the coinfection is explored.
