Reverse Squeeze Maxillary Sinus Barotrauma

A young female patient presented to ear, nose, and throat clinic with long history of left sided facial pain exacerbated while flying and being in high altitude. Examination of nasal cavity and computed tomography scan of sinuses suggested left maxillary sinus barotrauma. Endoscopic sinus surgery was performed completely resolving her symptoms. Based on her symptoms and examination findings she had reverse squeeze sinus barotrauma.

A 74-year-old male patient presented to the outpatient department with left-sided epiphora and chronic dacryocystitis, without any history of head trauma or previous nasal or paranasal sinuses surgery. No abnormalities were noted at the time with the use of nasal endoscopy. The computed tomography scan however revealed an osteoma of the medial wall of the left maxillary sinus. An endonasal endoscopic dacryocystorhinostomy (DCR) with osteoma removal by using a drill with temporary silicone stenting of the nasolacrimal duct system was performed. Due to a granuloma formation at the DCR-window site 2 months postoperatively a revision-DCR was performed and the new window remained patent at control 6 months after surgery.

Odontogenic Neoplasm

Ameloblastoma (AM) is a slow growing and aggressive benign tumor with an odontogenic epithelial origin arising from the mandible or maxilla. The odontogenic neoplasm invades local tissues asymptomatically and accounts for 1% of oral tumors and over 10% of odontogenic tumors. A 64-year-old man with a history of allergic fungal rhinosinusitis (AFRS) undergoing a revision image-guided endoscopic sinus surgery was found to have a fibrous mass suspicious of malignancy projecting inferolaterally and attached to the floor of the left maxillary sinus. Diagnostic biopsies were taken, and additional surgery was required to successfully resect the tumor via a transnasal endoscopic dissection. Multiple permanent pathology samples concluded the diagnosis of an AM. Endoscopic investigations led to the incidental discovery and ultimate complete endoscopic resection of the AM. The utilization of an endoscopic resection compared to the traditional maxillectomy with reconstruction results in significant less short and long-term morbidity for the patient.

In this case, a young female presents to a community hospital complaining of headache. She has a history of migraine and reports that this headache feels typical. Routine blood work is drawn, and treatment is begun for her headache. However, before it is initiated, she has a seizure and is rendered comatose. A diagnosis of subarachnoid hemorrhage is made. She is intubated and transferred to another hospital for a computed tomography scan of her head. In the meantime, her blood work is returned, which reveals the cause of her seizure and her correct diagnosis. The case illustrates the potential benefit of medical caveats (cognitive forcing strategies).

Abstract Background Excessive dynamic airway collapse (EDAC) is an uncommon cause of high airway pressure during mechanical ventilation. However, EDAC is not widely recognized by anesthesiologists, and therefore, it is often misdiagnosed as asthma. Case presentation A 70-year-old woman with a history of asthma received anesthesia with sevoflurane for a laparotomic cholecystectomy. Under general anesthesia, she developed wheezing, high inspiratory pressure, and a shark-fin waveform on capnography, which was interpreted as an asthma attack. However, treatment with a bronchodilator was ineffective. Bronchoscopy revealed the collapse of the trachea and main bronchi upon expiration. We reviewed the preoperative computed tomography scan and saw bulging of the posterior membrane into the airway lumen, leading to a diagnosis of EDAC. Conclusions Although both EDAC and bronchospasm present as similar symptoms, the treatments are different. Bronchoscopy proved useful for distinguishing between these two entities. Positive end-expiratory pressure should be applied and bronchodilators avoided in EDAC.

In this work, we discovered a new phenomenon—asymptomatic COVID-19 infection, or covert case, during the pandemic. All the 3 patients had a history of exposure, with no symptoms, and no abnormalities were found in computed tomography scan or lab tests. Except for case 2, the other patients’ severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) nucleic acid tests were negative. But their anti-SARS-COV-2 nucleocapsid antibody showed a dynamic trend, consistent with the process of virus infection and clearance. A growing number of asymptomatic or covert cases need more attention. Lack of surveillance may lead to another outbreak. We hope to demonstrate our cases to attract the attention of governments or health authorities that covert cases should be the focus as well.

A 1.5-y-old spayed female Juliana pot-bellied pig was presented to the Purdue University Veterinary Teaching Hospital with a history of wasting and anorexia. Enlarged and partially mineralized lymph nodes were identified on radiographs and computed tomography scan. Generalized lymphadenomegaly and disseminated nodules in the lungs, liver, spleen, and kidneys were identified on postmortem examination. Histologic examination revealed caseonecrotic granulomas with numerous intracellular, acid-fast bacilli. Mycobacterium kansasii type II was identified as the etiologic agent by PCR amplification using universal Mycobacterium primers, direct sequencing of the PCR amplicon, and comparison to sequences in GenBank. We describe a case in a pot-bellied pig of mycobacteriosis caused by an atypical mycobacterial species and highlight the important role of laboratory testing in suspected cases of tuberculosis.

Amoebic colitis, caused by ingestion of water or food contaminated with the protozoan Entamoeba histolytica, can progress to a fulminant colitis. Computed tomography (CT) findings reported in the literature on this type of colitis are sparse. We present a 59-year-old male patient with a one-week history of progressive abdominal pain, abdominal distension and associated watery and bloody diarrhoea. A CT scan revealed deep ulcerations with submucosal and intramural tracking of contrast. Colonoscopy and biopsy confirmed a diagnosis of Amoebic colitis. The patient required a laparotomy and demised. Deep ulcerations with submucosal and intramural tracking of contrast on CT are diagnostic of fulminant amoebic colitis. Although not demonstrated at CT in this case, discontinuous bowel necrosis, omental wrapping (seen at laparotomy in our case) and neovascularisation of the bowel wall may be other features to look out for.

Tomography Scan

Primary tracheal synovial sarcoma is a rare malignancy and is usually found incidentally. Tumours can present with cough, dyspnoea, stridor and intermittent haemoptysis. The diagnosis is challenging because it is rare, and the symptoms may mimic other diseases of airway obstruction. A previously well 53-year-old man presented with an eight-month history of cough. He had a history of minimal haemoptysis a few months prior to presentation. Spirometry showed an obstructive pattern, and a computed tomography scan of the thorax revealed an intraluminal tracheal mass. This case highlights that a thorough initial evaluation, including spirometry, leads to an earlier diagnosis and successful treatment of this rare sarcoma.
