Benign inoperable tracheal stenosis in COVID versus non-COVID patients at the pandemic epicenter: a case series.

Background: The COVID-19 pandemic has exponentially expanded the number of patients requiring treatment for chronic respiratory failure. One consequence is an increase in the number of patients requiring intubation and mechanical ventilation. Benign inoperable tracheal stenosis presents a challenge, especially in COVID-19 patients. Methods: We describe a case series of 15 patients with Benign inoperable tracheal stenosis treated with interventional bronchoscopy over a 15-month period. These patients were divided into two groups, COVID and non-COVID. We used an electrocautery snare as an electrocautery knife to cut the stenotic segment followed by four injections of 1 mg submucosal Decadron via a Wang needle. Patients were subsequently followed by the pulmonary clinic. Institutional review board approval was not required as per our institutional policy for a retrospective case series. Results: There was a high degree of success with this intervention, with a low rate of recurrence. We also noticed the following differences between the two subgroups. COVID tracheal stenosis was longer in length, had a higher percentage of cartilage involvement, and was located more distal to cords than the non-COVID group. The median age was younger in the COVID group. Conclusions: COVID pandemic an enormous number of intubations and tracheotomies have been performed. As a result, there will be an increased prevalence of tracheal stenosis. Most of these cases can be effectively treated with surgery. Dealing with complex inoperable cases remains a dilemma. Our case series/research article is an attempt to provide an easy technique with a high cure rate.

Recurrent chylothorax as a consequence of esophageal stent.

Incidence of chylothorax post-esophageal stenting has not been reported. We present a 40-year-old female with metastatic breast cancer who presented with dyspnea. She was recently hospitalized for dysphagia secondary to a mediastinal mass requiring an esophageal stent. CT chest now reported large bilateral pleural effusions. A benign chylothorax was drained from the right side. After persistent high-output drainage, a review of her CT chest revealed thoracic duct impingement by the esophageal stent. The stent was retracted proximally, and pleural fluid output subsequently decreased. Repeat fluid analysis revealed a transudative effusion. This is the first reported case of esophageal stenting causing reversible chylothorax.

Endobronchial blood-patch: A novel technique for a persistent pleural air leak.

Introduction: Patients with severe COVID-19 Pneumonia requiring prolonged mechanical ventilation have an increased incidence of pneumothorax. Mechanically ventilated patients who are critically ill and develop a persistent air leak from pneumothorax are poor candidates for surgical repair. As the persistent air leak can be a significant barrier to vent-weaning and clinical stability, these patients present a unique clinical challenge. Clinical case: A 65-year-old male intubated and on prolonged mechanical ventilation for severe COVID-19 Pneumonia developed a pneumothorax complicated by a persistent alveolar-pleural fistula with a persistent air-leak. Given his critical state with ongoing pressor requirements and elevated vent requirements, surgical repair was not an option. A bedside bronchoscopy occlusion study with isolation of the air leak, and subsequent autologous endobronchial blood-patch repair with thrombin was performed with rapid and definitive resolution of the air leak. The patient progressed favorably, ultimately being weaned from the ventilator, decannulated, and walking out of the hospital. Conclusion: In critically ill ventilated patients with pneumothorax complicated by a persistent air-leak, bedside endobronchial evaluation and blood-patch repair is a feasible approach to management.

Primary pulmonary choriocarcinoma: a diagnostic dilemma.

We present a case of a 25-year-old Hispanic woman who presented to emergency department with chief complaint of left lower quadrant abdominal pain. Initial workup revealed positive pregnancy test. Serum human chorionic gonadotropin was 36,478 (normal range, 0 to 8.0) IU/mL. She underwent diagnostic laparoscopy with dilatation and curettage, which did not reveal any evidence of intrauterine or extrauterine pregnancy. Chest and abdomen radiographic findings were significant for a heterogenously enhancing 2.2×1.7×1.6 cm nodule in superior segment of the right lower lobe of the lung and a large perinephric hematoma. We performed radial endobronchial ultrasound-guided transbronchial biopsies of the right lower lobe lesion. Pathologic specimen revealed choriocarcinoma.

Pretracheal abscess following two weeks of endotracheal intubation.

Pretracheal abscess due to endotracheal intubation has not been reported in literature. We present a case of a female patient who was admitted with acute hypercapnic respiratory failure. Patient was initially managed with noninvasive ventilation but eventually was intubated after sustaining a cardiac arrest. She could not be extubated because of poor weaning parameters, so a tracheostomy was planned. During surgery, a pretracheal abscess was found with destruction of the second, third, and fourth tracheal rings and intact posterior tracheal wall. The possible risk factors, mechanism of injury, and preventive strategy of tracheal complication of intubation are discussed.

Devic syndrome: a diagnostic dilemma.

Neuromyelitis optica (NMO, also known as Devic syndrome or Devic disease) is a rare clinical entity. Early recognition and prompt treatment can save patients from long-term disability, especially in themonophasic variant of disease. A 24-year-old African American female presented with high-grade fever for 1 day associated with frontal headache, photophobia, and 2 episodes of nonbloody vomiting. She had a history of nonitchy vesicular rash with sudden diminution of vision in the left eye 2 weeks ago. Over the next 24 hours, she developed progressively worsening weakness and numbness in her left arm and left leg, which later involved all limbs. Left eye vision was reduced to light perception with light and accommodation reflexes intact. Lumbar puncture showed lymphocytic pleocytosis with elevated protein. On day 2, neurological examination exhibited quadriparises with hypereflexia and clonus. Magnetic resonance imaging showed diffuse hyperintense signals in the spinal cord in cervical and lumbar regions. An assessment of neuromyelitis optica was made. Anti-NMO antibodies were negative. On day 3, she was intubated because of progressive dyspnea. Plasmapheresis resulted in rapid improvement in respiratory and neurological status. She was extubated on the second day and transferred to floor on day 4. Later, the patient was discharged.

Inappropriate Use of Intravenous PPI for Stress Ulcer Prophylaxis in an Inner City Community Hospital.

BACKGROUND: Proton pump inhibitors (PPIs) are used for the treatment and prophylaxis of variety of acid peptic conditions including stress ulcers. There has been a persistent practice of their inappropriate use for stress ulcer prophylaxis. Purpose of our study was to measure the inappropriate use of Intravenous Proton Pump Inhibitors for stress ulcer prophylaxis and to estimate the financial burden. METHODS: We carried out a retrospective, analytic study from July 2008 to June 2009 in internal medicine department. Hospital pharmacy records were used to identify all patients who received IV PPI during hospital stay. Seventy-five percent of records were randomly chosen (n=1104). PPI application was defined as indicated according to AGA guidelines. RESULTS: Intravenous proton pump inhibitor (IV PPI) was prescribed for 68.5% of patients without any proper indication. The estimated cost of medication for inappropriate IV PPIS use during the study year was 18337 USD. CONCLUSIONS: A more rational use of PPI will have better impact on health care cost and is likely to add to patient safety.
