We present a patient with uncommon metastases of lung cancer. The patient has been followed-up for early stage laryngeal carcinoma in the remission and has had dyspeptic complaints as well. A 62-year-old male patient had epigastric complaints for three months. In the upper endoscopy, a biopsy specimen taken from the polyp in the second region of the duodenum was reported as squamous cell cancer. Immunohistochemical staining of tumor cells were positive for CK5/6, p40, and p63. A mass in the right lung was detected on thorax tomography. The result of the transthoracic needle biopsy indicated squamous cell cancer. Duodenal metastasis of lung cancer is highly unlikely. Lesions below 1 cm can be safely removed endoscopically. Duodenal metastasis of primary lung cancer can be considered in the differential diagnosis of resistant dyspepsia. Keywords: Dyspepsia, Squamos cell lung cancer, Duodenal metastasis

Ectopic adrenocorticotropic hormone (ACTH) syndrome is a rare cause of the Cushing’s syndrome. The occurrence of the ectopic ACTH syndrome presenting with severe hypokalaemia, metabolic alkalosis, and hypertension has been highlighted in case reports. However, presentation with lower gastrointestinal perforation is not known. We report the case of a 70-year-old male patient with severe hypokalaemia, metabolic alkalosis, hypertension, and colonic perforation as manifestations of an ACTH-secreting small cell lung carcinoma. Ectopic ACTH syndrome should be kept in mind as a cause of hypokalaemia, hypertension, and intestinal perforation in patients with lung carcinoma.

Objectives. To investigate insulin-like growth factor I (IGF-1) levels in response to hyperbaric oxygen therapy (HBOT) for diabetic foot ulcers and to determine whether IGF-1 is a predictive indicator of wound healing in patients with diabetic foot ulcers. Design and Methods. We treated 48 consecutive patients with diabetic foot ulcers with HBOT. Alterations of IGF-1 levels in patients whose wound healed with HBOT were compared with those in patients who did not benefit from HBOT. Results. There was no significant difference in initial IGF-1 levels between the two groups (P=0.399). The mean IGF-1 level increased with HBOT (P
