Abstract Objectives

The aim of this retrospective study was whether serum Tg predicts malignancy in follicular or Hürthle-cell neoplasms on fine needle aspiration.

Methods

A chart review of 111 patients (90 females, 21 males; mean age 46.8 ± 11.9 years) with follicular or Hürthle-cell neoplasms on fine needle aspiration, who were surgically treated between Sep. 2001 and Sep. 2011, was performed. Predictive factors for malignancy were identified by the chi-squared test and multivariate logistic regression.

Results

There were no differences between 41 malignant and 70 benign lesions in serum Tg or any of the normalized indexes. Receiver-operator characteristic analysis revealed no cutoff value. Lesions with serum Tg levels greater than 500 g/L had no significant difference. And also there were no independent predictors of malignancy by multivariate logistic regression.

Conclusions

In this study, the author found that serum Tg has poor accuracy for predicting malignancy in follicular or Hürthle cell neoplasms on fine needle aspiration.

Abstract Objectives

The aim of this study was to explore the changes of bronchoscopic features according to epidemiologic change of lung cancer.

Methods

We performed a retrospective review of the clinical characteristics of 1,139 lung cancer patient who underwent bronchoscopy at Kosin University Hospital from January 2000 to December 2010.

Results

The age of patients increased significantly during the last decade (P < 0.001). The most common histological type was adenocarcinoma (38.1%), followed by squamous carcinoma (35.7%) and small cell carcinoma (15.3%). There was an increasing incidence of adenocarcinoma over the time (P < 0.001). Bronchoscopic feature were divided into two classes; central type, peripheral type. The peripheral type was predominant (62.3%). The proportion of peripheral type has been increased in process of time (49.7% vs. 63.7% vs. 73.7%; P < 0.01). Among the major histopathologic type of lung cancer, adenocarcinoma (81.3%) and unclassifiable non-small-cell lung cancer (73.4%), small cell carcinoma (56.9%) were associated with preferential occurrence of peripheral type. Squamous cell carcinoma of the lung more often arised in central type (59%). However, the proportion of peripheral squamous cell carcinoma has been increased. On the subgroup analysis, the median survival time of peripheral type with adenocarcinoma and small cell carcinoma were longer than central type (P < 0.05).

Conclusions

The age of the lung cancer patients at diagnosis was getting older. The most frequent histopathologic type was adenocarcinoma. The proportion of peripheral type lung cancer gradually increased over the time. The survival time of peripheral type lung cancer was longer than central type.

Pheochromocytoma is a catecholamine-producing tumor characterized by hypertension, headache, tachycardia, excessive diaphoresis, and angina pectoris. The thunderclap headache is so named because the pain strikes suddenly and severely. Although the symptoms of bladder pheochromocytoma are rather evident, the diagnosis of this rare neuroendocrine tumor can be missed. This study reports the case of a woman diagnosed with bladder pheochromocytoma who experienced thunderclap headache triggered by urination and angina pectoris as an initial manifestation. This case study suggests that thunderclap headache and angina pectoris occurring concurrently with sudden blood pressure elevation during or immediately after urination are important diagnostic clues of bladder pheochromocytoma.
