Slide tracheoplasty for congenital tracheal stenosis with involvement of the carina and bronchi: a case report
DOI: 10.31744/einstein_journal/2024RC0659
ABSTRACT A female newborn presented with respiratory distress at birth and was diagnosed with congenital tracheal stenosis. The stenosis was positioned at the distal trachea and compromised the carina and the right and left bronchi. She underwent surgical treatment using circulatory life support with veno-arterial peripheral extracorporeal membrane oxygenation, and the airway was reconstructed using the slide tracheoplasty technique to build a neocarina. The patient had an excellent postoperative course, was successfully weaned from extracorporeal membrane oxygenation and invasive ventilation, […]

Torsades de pointes and myocardial infarction following reversal of supraventricular tachycardia with adenosine: a case report
DOI: 10.31744/einstein_journal/2024RC0522
ABSTRACT Adenosine is an antiarrhythmic drug that slows conduction through the atrioventricular node and acts as a coronary blood vessel dilator. This case report highlights two unusual life-threatening events following the use of adenosine to revert supraventricular tachycardia in a structurally normal heart: non-sustained polymorphic ventricular tachycardia and myocardial infarction. A 46-year-old woman presented to the emergency department with a two-hour history of palpitations and was diagnosed with supraventricular tachycardia. Vagal maneuvers were ineffective, and after intravenous adenosine administration, the […]

Benign cervical schwannoma with tracheal invasion
DOI: 10.31744/einstein_journal/2024RC0528
ABSTRACT Schwannomas commonly develop in the cervical region, 25% – 45% of cases are diagnosed in this anatomical region. Tracheal neurogenic tumors are exceedingly rare and can be misdiagnosed as invasive thyroid carcinomas or other infiltrating malignancies when present at the level of the thyroid gland. Here, we present a case of synchronous benign cervical schwannoma with tracheal invasion and papillary thyroid carcinoma in a patient who was initially hospitalized for COVID-19. The patient presented with dyspnea that was later […]

Littoral cell angioma of the spleen: case report and literature review
DOI: 10.31744/einstein_journal/2024RC0267
ABSTRACT Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the […]

Risk of pulmonary aspiration during semaglutide use and anesthesia in a fasting patient: a case report with tomographic evidence
DOI: 10.31744/einstein_journal/2023RC0628
ABSTRACT Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality […]

Antimicrobial peptide for bacterial infection imaging: first case reported in Brazil
DOI: 10.31744/einstein_journal/2023RC0621
ABSTRACT Molecular imaging markers can be used to differentiate between infection and aseptic inflammation, determine the severity of infection, and monitor treatment responses. One of these markers is ubiquicidin(29-41) (UBI), a cationic peptide fragment that binds to the bacterial membrane wall and is labeled with gallium-68 (68Ga), a positron emitter radioisotope. The use of UBI in positron emission tomography (PET)/computed tomography (CT) for improved detection of lesions has been receiving considerable attention recently. Herein, we report the first case of […]

Combined larynx large cell neuroendocrine and squamous cell carcinoma: a case report
DOI: 10.31744/einstein_journal/2023RC0618
ABSTRACT Laryngeal cancer ranks third among the most common head and neck neoplasms. The most common histological subtype is squamous cell carcinoma, and neuroendocrine tumors are rare. An even rarer entity is a composite tumor with both these histologies. This case reports a metastatic combined carcinoma of squamous cells and large neuroendocrine cells, presenting favorable response to treatment with a total laryngectomy followed by adjuvant therapy including chemo-, radio-, and immunotherapy.

A peculiar case of onychomycosis caused by Cladosporium halotolerans
DOI: 10.31744/einstein_journal/2023RC0326
ABSTRACT A 49-year-old patient with changes in the nails of the hallux for 10 years was diagnosed with onychomycosis. The identity of the causative agent was confirmed as Cladosporium halotolerans from the Cladosporium sphaerospermum species complex using molecular techniques. MALDI-TOF identified the agent as C. sphaerospermum complex species. Overall, species such as onychomycosis agents should attract special attention to avoid mistakes in the identification process while considering a probable contaminant as responsible for the disease. These species deserve attention since […]

Phenocopy in a patient with triple negative breast cancer: a case report
DOI: 10.31744/einstein_journal/2023RC0319
ABSTRACT A total of 1.67 million breast cancer cases per year are reported worldwide. Of these, 5%–10% are caused by inherited mutations. Phenocopy is a rare phenomenon, with only a few cases reported in the literature. In phenocopies, phenotypes identical to those with genetic origin occur because of environmental factors rather than familial mutations. We describe a case of phenocopy in a 44-year-old female patient with triple-negative breast cancer. The mother and sister wee heterozygous for c.1813delA, p.Ile605TyrfsTer9 in BRCA2 […]

Robotic approach to remove four tailgut cyst cases in Brazil: a case series
DOI: 10.31744/einstein_journal/2023RC0544
ABSTRACT Tailgut cysts are rare congenital lesions that are remnants of the embryonic hindgut. This abnormality presents with non-specific symptoms or no symptoms; therefore, misdiagnosis is common. Here, we present four cases of tailgut cysts that were successfully removed using a robotic surgical approach. A 42-year-old woman with tenesmus, pain in the right gluteal region, and discomfort in the rectal region during evacuation was referred to our medical center. Another patient was a 28-year-old woman who presented with the same […]
