BACKGROUND: Circumferential pulmonary vein (PV) isolation for atrial fibrillation (AF) is occasionally difficult to achieve because electrical breakthrough sites (EBSs) between the left atrium (LA) and PVs cannot be identified during ablation especially in the carina regions. METHODS: The left PVs (Lt.PVs) of 60 AF patients and the right PVs (Rt.PVs) of 37 patients undergoing PV isolation were studied. When PV isolation was not achieved after the initial circumferential PV isolation, atrial pacing was repeatedly performed from the distal coronary sinus (CSd) and high right atrium (HRA), and the time interval from the stimulus to the earliest PV potential (stimulus-PV interval) was measured using circular mapping catheters at each PV until PV isolation was achieved...

Desmoid tumor is a rare monoclonal fibroblast proliferation that is regarded as benign. The clinical management of desmoid tumors is very complex and requires a multidisciplinary approach because of the unpredictable disease course. For those cases localized in the anterior abdominal wall, symptomatic and unresponsive to medical treatment, radical resection and reconstruction with a prosthetic device are indicated. We present here a case of desmoid fibromatosis of the left anterolateral abdominal wall with a marked increase of the mass that required a large excision followed by reconstruction with biological matrix...

BACKGROUND: Anterior cutaneous nerve entrapment syndrome (ACNES) is a neuropathic abdominal wall pain syndrome typically characterized by locally altered skin sensations. On the other hand, visceral disease may also be associated with similar painful and altered skin sensations ("Head zones"). Aim of the study was to determine if patients with acute appendicitis demonstrated somatosensory disturbances in the corresponding right lower quadrant Head zone. METHODS: The presence of somatosensory disturbances such as hyperalgesia, hypoesthesia, altered cool perception, or positive pinch test was determined in 100 patients before and after an appendectomy...

BACKGROUND AND PURPOSE: Intracranial aneurysm (IA), common in general public, causes lethal subarachnoid hemorrhage on rupture. Prevention of rupture of IA is therefore socially important. However, there is currently no medical treatment. Recent studies suggest that IA is a disease of chronic inflammation in the arterial wall caused by endothelial dysfunction and infiltrated macrophages. Sphingosine-1-phosphate receptor type 1 (S1P1 ) is present on the endothelium and promotes its barrier function...

We present a technique for anterior cruciate ligament (ACL) reconstruction using hamstring tendon autograft with a modified transtibial technique. Our modified transtibial technique has the advantages of the conventional transtibial technique that is familiar to surgeons and that allows the press-fit fixing and enables us to make a relatively long femoral tunnel. To make the femoral tunnel at the anatomic position, the triangular, funnel-shaped bony trough was made to slip the eccentrically positioned guide pin into the anticipated anatomic center with a free-hand technique after marking the anatomic ACL footprint using a microfracture awl through the anteromedial portal...

BACKGROUND: Patients with symptomatic umbilical, trocar, and/or epigastric hernias and concomitant rectus abdominis diastasis represent a growing clinical problem. The optimal management of this complex hernia situation is the subject of debate in the literature. This paper reports the early results of an innovative surgical technique aimed at managing this hernia situation. METHODS: Endoscopic-assisted linea alba reconstruction (ELAR) with mesh augmentation is a surgical technique long known in the literature for its good outcome for incisional hernia repair (myofascial release, overlapping herniorrhaphy, Gibson's operation, shoelace repair, anterior rectus sheath repair, dynamic patch plasty) via a small access route...

A 19-year-old male patient was observed due to having central diabetes insipidus (DI) for five years. He had a history of smoking 5-10 cigarettes a day for two years, but stopped smoking from the last month. The computerized tomography revealed thin-walled cystic lesions in different sizes more dominantly in the upper lobes and consolidated areas in the left upper and lower lobes. The wedge resection from the right lower lobe revealed pulmonary langerhans cell histiocytosis. Follow-up acid-fast bacteria (AFB) examinations revealed (+++) and antituberculous treatment was started...
