Multidisciplinary Team in Severe Infectious Complications Caused by Pharyngeal Foreign Body.

BACKGROUND: Pharyngeal foreign body is not only a common emergency in people's daily life, but also a common simple disease in otorhinolaryngology. However, the disease is easy to be ignored due to its common occurrence, which may lead to a series of serious complications including sepsis and local abscess. CASE PRESENTATION: In this case, a patient with sepsis, piriform fistula, deep neck abscess, and mediastinal abscess caused by a fishbone was reported. After reviewing the international literature on severe infectious complications caused by foreign bodies in pharynx, the authors emphasize the important role of multidisciplinary team in dealing with complex complications. RESULT: The whole process of patient from onset to recovery was summarized in a timeline. During hospitalization, the value of leukocyte counts and C-reactive protein in routine blood test was record dynamically. The electronic laryngoscopy, neck computed tomography and chest computed tomography were used to judge treatment efficacy. After about 2 months of hospitalization, the patient was recovered without sequelae. No adverse reactions were found during the follow-up. CONCLUSION: The incorrect method of removing foreign body after mis-swallowing may develop serious complications. Therefore, It is important to strengthen medical preaching for general population of correct treatments after foreign body ingestion. In addition, the case reminds clinicians to pay more attention to patients' medical history and details of all medical examinations, which may provide significant clues for making the correct diagnosis and treatment quickly.

A Review of Microsurgical Resection of Recurrent Laryngeal Neurilemmoma Under Nerve Monitoring.

BACKGROUND: Laryngeal neurilemmoma, especially recurrent laryngeal neurilemmoma, is a rare neural sheath tumor in head and neck. The most common symptom of laryngeal neurilemmoma is hoarseness or dysphonia, followed by dysphagia, dyspnea, and foreign body sensation. At present, surgical resection is the most effective treatment for this kind of tumor, thus making how to remove it become the most concerned problem of surgeons. CASE PRESENTATION: On February 18, 2021, a 64-year-old male presented to our clinic with recurrent sore throat and intermittent hoarseness for 3 years. The results of electronic laryngoscope and magnetic resonance imaging showed a 25×10×21 mm well-defined tumor in the left pyriform sinus without laryngeal cartilage destruction and enlarged lymph nodes. After the initial diagnosis of recurrent laryngeal neurilemmoma, to preserve the continuity of recurrent laryngeal nerve as much as possible, the authors determine to perform anatomical resection of recurrent laryngeal neurilemmoma with operating microscope under the monitoring of recurrent laryngeal nerve function. Finally, the patient recovered completely from hoarseness during postoperative follow-up. CONCLUSION: A complete diagnosis and treatment process of recurrent laryngeal neurilemmoma was presented by the case. Particularly, it shows the application of recurrent laryngeal nerve monitoring in the operation helps to protect the continuity of the recurrent laryngeal nerve, which lays a anatomical bases for the follow-up nerve repair.

[Impacts of electromagnetic radiation from cellphones and Wi-Fi on spermatogenesis].

With the development of Wi-Fi technology and widespread exposure to electromagnetic radiation (EMR), people are increasingly concerned about the health hazards caused by radiofrequency electromagnetic fields as from cellphones and Wi-Fi, particularly about the current decline in sperm concentration and increase in male infertility. Long-term exposure to EMR not only damages male reproductive organs, but also affects the number, morphology, motility and oocyte-binding ability of sperm, and indirectly increases the risk of infertility. However, EMR is not unavoidable. Low-intensity short-term or intermittent exposure to EMR has little adverse effect on reproductive organs and sperm. And many antioxidant and anti-free radical agents, such as vitamin E and melatonin, can protect some special populations from EMR. This review presents an overview of the impacts of EMR from cellphones and Wi-Fi on sperm, some countermeasures, and prospects of EMR protection.
