Bilateral Recurrent Laryngeal Nerve Injury Following Botulinum Toxin Injection at the Cricopharyngeus Muscle: Diagnosis, Anatomic Considerations, and ICU Management.

Bilateral vocal cord paralysis poses life-threatening risks to patients who do not undergo prompt diagnostic intervention and airway management. Although developing bilateral vocal cord paralysis is extremely rare, if injury does occur, it is more frequently due to surgical resection sequelae in the neck. This case is particularly unique as we present a patient with a history of stage III laryngeal carcinoma status post chemotherapy in remission, who developed respiratory distress three days following an upper endoscopy procedure for an esophageal stricture at the level of the cricopharyngeus muscle, where he received a botulinum injection. This manuscript discusses the anatomy, clinical practices of botulinum toxin, nerve innervation, and mechanisms of injury for patients who develop bilateral recurrent laryngeal nerve injury. In addition, this manuscript details vocal cord positioning and how the positioning of the cords during laryngoscopy investigation can lead to diagnostic confirmation. With few reported cases of bilateral recurrent laryngeal nerve injury secondary to botulinum toxin particularly at the cricopharyngeus level, this report should serve as a guide for future clinicians regarding the risks of using this toxin, the risks of local spread, and management.

Effectiveness of Osteopathic Manipulative Treatment on Hemodynamic and Pulmonary Response in Coronary Artery Bypass Graft Patients: A Meta-Analysis.

In the realm of cardiovascular care, the quest for innovative and holistic approaches to enhance patient outcomes persists. This study analyzes osteopathic manipulative treatment (OMT) and its potential impact on pain intensity, length of hospitalization, respiratory function, and hemodynamic response in patients undergoing coronary artery bypass grafting (CABG). OMT, with its emphasis on physical manipulation of the body's muscles and tissues, presents a potential treatment beyond the realms of conventional post-operative care. Google Scholar was used to identify four relevant articles for further review. RevMan 5.4 was utilized for meta-analytic evaluation in order to produce forest plots with associated standardized mean difference (SMD), confidence interval (CI), and heterogeneity (I²). Output from collection and analysis revealed statistically significant decreases in negatively viewed outcomes, including length of stay (SMD 0.39; 95% CI -0.02,-0.76; I² ≤ 0%) and pain control (SMD 1.67; 95% CI -1.34,-0.67; I² ≤ 94%). Parameters for respiratory function and hemodynamic response, including vital capacity (SMD 0.91; 95% CI 0.57,1.24; I² ≤ 96%) and maximal aerobic capacity (SMD 0.50; 95% CI 0.19, 0.82; I² ≤ 0%), showed a statistically significant increase. These findings suggest the incorporation of OMT as a viable adjunct for postoperative management in CABG patients, yielding favorable reductions in adverse outcomes such as length of hospitalization and pain. Moreover, it has demonstrated enhancement in maximal aerobic and vital capacity. This study suggests that the addition of osteopathic management to post-bypass standards can ultimately prevent certain morbidities associated with this specific patient population.

Deep Neck Cellulitis, Myositis, and Reactive Lymphadenitis Secondary to Rothia dentocariosa in an Immunocompetent Female: A Case Report.

Rothia dentocariosa is a commensal organism that is typically found in the oropharyngeal and respiratory tracts, and it typically possesses a low virulence profile, especially for immunocompetent patients. The case presented here represents an extremely rare case of deep neck cellulitis, myositis, and reactive lymphadenitis secondary to R. dentocariosa in an immunocompetent female. A 35-year-old female with no significant past medical history presented to the emergency department with neck pain with reduced range of motion, fever, chills, sinus congestion, and headache for one day. After a thorough workup, blood cultures grew R. dentocariosa in the days following admission. The patient subsequently recovered without any notable sequelae after proper antibiotic treatment. Since Rothia species are currently considered a low-virulence organism that typically causes endocarditis in immunocompromised hosts, this case should serve as a reference for its possible virulence level in immunocompetent hosts. In spite of this organism's pathological rarity, this case highlights the importance of understanding the microbiology, historical context, and treatment for R. dentocariosa as a cause for deep neck cellulitis, myositis, and reactive lymphadenitis.

Dual Malignancies Discovered: A Rare Case of Malignant Peritoneal Epithelioid Mesothelioma and Lung Adenocarcinoma.

Clinicians diagnosing malignant peritoneal epithelioid mesothelioma (MPM or MPeM) have historically had challenges due to the low incidence of the disease, as well as the often vague symptomatology that patients present with. Newer advances in technology, specifically in immunocytochemistry, have provided a clearer path to diagnosis. Additionally, malignant mesotheliomas must be differentiated from carcinomas. This is done via histology, immunocytochemistry, as well as a careful incorporation of the patient's clinical history. In this case, we present an asymptomatic 73-year-old non-smoker female with no past medical history of asbestos exposure. She was diagnosed with MPM following a routine abdominal hernia repair. Subsequent workup revealed a lung infiltrate that was successfully biopsied and resected, evidently found to be adenocarcinoma. A careful review of the resulting pathology, as well as the interpretation of immunocytochemistry, supported the notion that the patient had two independent malignant processes occurring at once. This case underscores the rarity of two similar, yet distinct cancers, as well as epidemiology, symptomatology, histology, immunocytochemistry, and prognosis.

Pyloric Stenosis in a Patient with CEDNIK Syndrome.

We present a rare neurocutaneous genetic disorder where patients develop a combination of cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma, commonly known as CEDNIK syndrome. It is an autosomal recessive inheritance involving the SNAP29 protein, mapped to the 22q11.2 gene. Phenotypic variation is seen with this disease, with clinical manifestation of developmental milestone delays ranging in severity. With only a handful of documented cases, available research, management of the syndrome, and prognosis are not well established. As CEDNIK syndrome has systemic implications, care coordination between specialists is essential in improving patient outcomes. Particularly important is preventing patients from meeting the criteria of failure to thrive, a commonly reported issue. In this case, we present a four-month-old male with a past medical history of pyloric stenosis status/post pyloromyotomy who has failure to thrive, gastroesophageal reflux disease, profound hypotonia, and delayed progression of developmental milestones. Additionally, the case is complicated by idiopathic pyloric stenosis, further contributing to the patient's failure to thrive. We aim to discuss the pathophysiology of this syndrome, explore the timeline of disease progression, as well as compare our case to the current literature.

Alloyed Airways: Chromium, Beryllium, and Titanium in the Lungs of an Aerospace Veteran.

Pneumoconiosis is a form of interstitial lung disease (ILD) that commonly occurs secondary to occupational or environmental exposures. This is an emerging disease as there are many potential forms of pathologic insults. Further adding to the complication is that clinical symptomatology secondary to pneumoconiosis can have long latent periods, as repetitive exposure over years leads to long-standing inflammation and subsequent irreversible damage. Exposure to asbestos, coal, silica, aluminum, talc, hay, and many more agents has the potential to cause pneumoconiosis. This case highlights a veteran, who made his career working with heavy metals such as chromium, beryllium, and titanium in the aerospace defense industry. This case discusses high-risk occupations, a workup for suspected pneumoconiosis, management, and the mechanism of lung injury underlying the three aforementioned pathologic agents. In each case of pneumoconiosis, a thorough history is essential, and diagnoses are made via the incorporation of the patient's historical risk factors, pulmonary function test (PFT) findings, and high-resolution chest computed tomography (HRCT).
