Functional Olfactory Nerve Regeneration Demonstrated by Thallium-201 Olfacto-Scintigraphy in Patients with Traumatic Anosmia: A Case Report.

Head trauma is one of the most common etiologies of olfactory dysfunction. It is difficult to use either the olfactory function test or magnetic resonance imaging to directly assess the course of damage to olfactory nerves. Thallium-201 (Tl) olfacto-scintigraphy has been shown to be an able means for objectively assessing the olfactory nerve transport function.

Clitoral Metastasis From Advanced Cervical Carcinoma on 18F-FDG-PET/CT.

Metastatic tumors of the clitoris from cervical carcinoma are extremely rare. Here, we described a 54-year-old woman with clitoral metastasis from cervical carcinoma demonstrated on F-FDG PET/CT images.

To evaluate the treatment response of locally advanced esophageal cancer after preoperative chemoradiotherapy by FDG-PET/CT scan.

Background: This study was designed to gauge the effectiveness of evaluation of tumor response and prognosis by positron emission tomography with 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) before and after preoperative chemoradiotherapy in patients with esophageal cancer.

Methods: Forty-nine patients from October 2008 to September 2012 with locally advanced stage esophageal carcinoma, clinical stage T2-4N0-3M0, who underwent preoperative chemoradiotherapy (pre-CRT) followed by esophagectomy were enrolled in our study. All patients underwent two FDG-PET scans to compare those results with the pathologic results.

Laryngo-tracheobronchial amyloidosis: a case report and review of literature.

AMYLOIDOSIS is a benign process which can have systemic involvement. Though larynx is the common site of localized amyloidosis in the head and neck region,1 it was seldom reported with heterochronous implication of bilateral ventricles. Here we report a case of laryngeal amyloidosis heterochronously localized at bilateral ventricles with tracheobronchial involvement.

18F-FDG PET or PET/CT for detecting extensive disease in small-cell lung cancer: a systematic review and meta-analysis.

The purpose of this study was to conduct a systematic review and meta-analysis of the published literature to evaluate the diagnostic accuracy of fluorine-18 2-fluoro-2-deoxy-D-glucose (F-FDG) PET or PET/computed tomography (CT) in the pretherapeutic staging of patients with small-cell lung cancer (SCLC). The authors conducted a systematic MEDLINE search of published articles. Two reviewers independently assessed the methodological quality of each study.

FDG PET/CT for the preoperative nodal staging of non-small cell lung cancer in a tuberculosis-endemic country: Are maximum standardized uptake values useful?

Background: The aim of this study was to determine an optimum standardized uptake value threshold for identifying nodal metastasis in non-small cell lung cancer (NSCLC) patients using Fluorine-18 2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) in Taiwan, a tuberculosis-endemic country. The variation in standardized uptake values of nodal metastasis among different NSCLC histological subtypes was also evaluated.

Methods: We retrospectively reviewed 75 NSCLC patients who had received FDG PET/CT before surgery.

A mass resulting from cerebral spinal fluid collection of ventriculopleural shunt: radiographic and radionuclide findings.

A 49-year-old man was brought to our hospital because of lethargy. His medical history was hydrocephalus with ventriculoperitoneal shunt initially. The ventriculoperitoneal shunt was replaced several times owing to malfunction, and it was later replaced with a right-sided ventriculopleural shunt.

The Value of Changing Position in the Detection of CSF Leakage in Spontaneous Intracranial Hypotension Using Tc-99m DTPA Scintigraphy: Two Case Reports.

Radionuclide Cisternography (RNC) is of potential value in pointing out the sites of cerebrospinal fluid (CSF) leakage in patients with spontaneous intracranial hypotension (SIH). In the current report, we present two patients who underwent RNC for suspected CSF leakage. Both patients underwent magnetic resonance imaging (MRI) and RNC for evaluation.

Meta-analysis of the diagnostic performance of [18F]FDG-PET and PET/CT in renal cell carcinoma.

Objectives: Positron emission tomography (PET) using fluorodeoxyglucose (FDG) is useful for restaging renal cell carcinoma (RCC) and detecting metastatic diseases but is less satisfactory for detecting primary disease. We evaluated whether the integration of computed tomography (CT) scans with the PET system could increase the applicability of FDG-PET for RCC.

Methods: The MEDLINE databases were searched for relevant studies published since 2001.

A systematic review and meta-analysis of pretherapeutic lymph node staging of colorectal cancer by 18F-FDG PET or PET/CT.

The purpose of the present study was to conduct a systematic review and meta-analysis of the published literature to evaluate the diagnostic performance of fluorine-18 2-fluoro-2-deoxy-D-glucose (18F-FDG) PET in the pretherapeutic assessment of nodal staging in patients with colorectal cancer (CRC). We conducted a systematic MEDLINE search of articles in the published literature (last update, February 2012). Two reviewers independently assessed the methodological quality of each study.

FDG PET or PET/CT for detecting intramedullary and extramedullary lesions in multiple Myeloma: a systematic review and meta-analysis.

Aim: The purpose of the current study was to conduct a systematic review and meta-analysis of the published literature to evaluate the diagnostic accuracy of FDG PET or PET/CT for intramedullary and extramedullary lesions in multiple myeloma.

Methods: The authors conducted a systematic MEDLINE search of published articles. Two reviewers independently assessed the methodological quality of each study.

Regional cerebral blood flow in patients with carbon monoxide intoxication.

Rationale And Objectives: Early detection of regional cerebral anomalies in acute carbon monoxide (CO) poisoning by (99m)Tc-hexamethylprophylene amine oxime (HMPAO) brain single photon emission computed tomography (SPECT) imaging has been reported previously. However, SPECT findings varied in these studies because of their small population sizes. In this study, we included 96 patients with acute CO intoxication and analyzed the regional perfusion changes in these patients by means of HMPAO brain SPECT.

Materials And Methods: The authors conducted a systematic MEDLINE search of articles published between January 2000 and December 2010. Two reviewers independently assessed the methodological quality of each study.

Bacterial biofilms in chronic rhinosinusitis and their relationship with inflammation severity.

Aims: To identify the presence of bacterial biofilms on mucosal specimens from chronic rhinosinusitis (CRS) patients, and evaluate their relationship with severity of CRS.

Daily intake of 4-nonylphenol in Taiwanese.

Alkylphenol polyethoxylates (APEO), alkylphenols combined with ethylene oxide, are a class of nonionic surfactants. APEO have been widely used for industrial, agricultural and household applications, and are biodegraded to more persistent and estrogen-active products, namely, nonylphenol (NP), octylphenol (OP), butylphenol (BP), nonylphenol monoethoxylate (NP(1)EO) and nonylphenol diethoxylate (NP(2)EO). This study determined NP levels in commonly consumed foodstuffs to assess daily intake of NP in a Taiwanese population.
