It is imperative that surgeons should have some knowledge and understanding of the beliefs of Jehovah's Witnesses to respect the patient's wishes and effectively minimize and manage blood loss. The objective of this review was to provide a management strategy for Jehovah's Witness patients undergoing otolaryngology, head and neck surgery, because there is paucity of information regarding this within our literature. A systematic review of medical literature was conducted. ⋯ The search strategy used Medical Subject Heading terms Jehovah's Witnesses, Beliefs, Ethical and Legal issues, Blood transfusion alternatives, ENT, Head and Neck surgery in Jehovah' witnesses. There is a broad range of nonblood surgical management strategies available in other specialities, making major surgery possible within this population. This review suggests recommendations in elective surgery, trauma, and emergencies.

The concept of donor bone marrow transplantation has been successfully used in human solid organ transplantation to increase recipient chimerism. The development of recipient chimerism is associated with a decreased need for immunosuppression and even donor-specific tolerance. In this study, we attempted to augment recipient chimerism by the transfer of donor bone marrow at the time of rat laryngeal transplant. ⋯ In the rat laryngeal transplant model, donor bone marrow does not consistently lead to augmentation of peripheral chimerism using our established pulsed immunosuppression protocol. In many cases, rejection occurred earlier than animals not receiving bone marrow. This may be due to several different factors including (1) an element of graft-vs-host disease, (2) inability to establish bone marrow engraftment due to our short-term perioperative immunosuppression regimen, or (3) preferential rejection of donor bone marrow cells.

The purpose of this report is to demonstrate a unique case of severe bronchial stricture and discuss the associated diagnostic and airway management challenges. ⋯ Bronchial strictures and atresias may go undiagnosed for years before pulmonary symptoms occur. Computed tomography and bronchoscopy with biopsies represent the mainstays of diagnosis. Regional lung hyperinflation and peribronchial translucency may hint at bronchial atresia. Treatment paradigms vary from dilation and stent placement to resection of the affected areas. In the absence of a clear etiology for lung whiteout, severe bronchial stricture or atresia should be considered as a possibility.

The aim of this study was to determine the accuracy of the fluorine 18 ((18)F)-labeled fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scan in the evaluation of thyroid nodules in which the cytopathology of fine-needle aspiration (FNA) biopsies are classified as "indeterminate," ie, either follicular or Hürthle cell lesion. ⋯ In this pilot study of patients with cytologically indeterminate thyroid nodules, FDG-PET/CT was not a predictable indicator of benign or malignant disease. Although a larger series may elucidate a role for FDG-PET/CT, the relatively low predictability shown in this study should caution clinicians about using FDG-PET/CT to consider foregoing thyroidectomy for cytologically indeterminate nodules.

The purpose of this study is to demonstrate that pseudotumor cerebri, also known as benign intracranial hypertension, can be an overlooked cause of spontaneous, nontraumatic cerebrospinal fluid (CSF) rhinorrhea. ⋯ Cerebrospinal fluid rhinorrhea is most often the result of trauma, but it may also occur spontaneously because of nontraumatic causes in some patients. Pseudotumor cerebri can be an overlooked cause of spontaneous, nontraumatic CSF rhinorrhea. A patient with signs and symptoms of pseudotumor cerebri should be evaluated and treated, if the condition is present, to prevent complications that include irreversible visual loss and CSF rhinorrhea.
