Flexible fibreoptic bronchoscopy is frequently performed in patients with endoscopically not visible lesions, especially for establishing a diagnosis in patients with peripheral lung cancer. The usual method for obtaining material for histological analysis is transbronchial forceps biopsy. To gain material for cytological examination transbronchial needle aspiration, transbronchial catheter aspiration or bronchial brushing and bronchial washing can be used. ⋯ In a direct comparison, cytological examination of material from transbronchial needle aspiration and transbronchial catheter aspiration has been found to have a significantly higher diagnostic sensitivity than transbronchial forceps biopsy in peripheral bronchial carcinoma. While transbronchial needle aspiration makes it possible to obtain tissue from extrabronchial region, catheter aspiration provides material of a larger area of the bronchial mucosa. There is thus no need for an exact positioning of the catheter tip inside the lesion under fluoroscopic guidance.

Review[Chemotherapy induced-vomiting--a practical guide for prevention and therapy].
Nausea and vomiting are considered as two of the most distressing side effects of chemotherapy. The frequency of nausea and vomiting depends primarily on the emetogenic potential of the chemotherapeutic agents used. With the introduction of the neurokinin-1-receptor-antagonists in combination with 5-HT(3) receptor-antagonists and steroid approximately 70-90 % of patients receiving highly emetogenic chemotherapy can be protected from emesis. Here, the most recent developments in the antiemetic therapy including the latest guidelines for antiemetic prophylaxis are described.
