Spatiotemporal distribution of proliferation, proapoptotic and antiapoptotic factors in the early human limb development.

Involvement of proliferation and apoptosis in the human limb development was analyzed electronmicroscopically and immunohistochemically in histological sections of 8 human embryos, 4(th) -10(th) week old, using apoptotic (caspase-3, AIF, BAX), anti-apoptotic (Bcl-2) and proliferation (Ki-67) markers, and TUNEL method. The data were analyzed by Mann-Whitney test, Kruskal-Wallis and Dunn's post hoc test. Initially, developing human limbs consisted of mesenchymal core and surface ectoderm with apical ectodermal ridge (AER).

Computer representation of osteosynthesis stability in locking plates used for the treatment of osteoporotic proximal humerus fractures.

Background: Proximal humerus fractures are represented as 4-5% of all fractures, with incidence notably growing with age. Since surgical internal fixation in treatment of proximal humeral fractures is used, fractures of osteoporotic bone and choice of plate for their osteosynthesis represent particular problem. The aim of the study was to test two locking plates: Philos plate with locking screws with determinated direction, and Arthrex plate with poliaxial locking screws, using the finite element method.

Peutz-Jeghers syndrome complicated with intussusception: enteroscopic polyps resections through laparotomy.

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by intestinal hamartomatous polyps in association with mucocutaneous pigmentations. Here we present a case of a 30-year-old woman who was hospitalized and underwent diagnostic procedures because of crampy abdominal pain. Physical examination on admission revealed pigmented spots around lips and on the oral mucosa.

Subbrachial approach to humeral shaft fractures: new surgical technique and retrospective case series study.

Background: There are few surgical approaches for treating humeral shaft fractures. Here we present our results using a subbrachial approach.

Methods: We conducted a retrospective case series involving patients who had surgery for a humeral shaft fracture between January 1994 and January 2008.

Preperitoneal approach for femoral hernia repair.

Background/aims: Although Lichtenstein's procedure is the standard procedure in surgical hernia treatment, and the role of laparoscopic hernia repair is constantly increasing, preperitoneal approach for femoral hernia repair should be equally considered.

Methodology: After the horizontal incision of transversal fascia, preperitoneal space is visualized. The hernial sac is opened and its content is placed in the abdominal cavity, or if there is a need, resection is performed.

Formation of adhesions at surgical meshes in a rat experimental model.

Abdominal wall hernias are surgical problem that are easily solved with laparoscopic surgery. The determining factor for the success of the operation is the right choice and use of surgical mesh as the support material. The most common complication of surgical mesh placement is the formation of adhesions.

Quality of life analysis after open and laparoscopic inguinal hernia repair--retrospective study.

Background/aims: An inguinal hernia is a usual medical problem. The golden standard for its treatment is Lichtenstein's repair. But, there are still some dilemmas about inguinal hernia repair technique, including the role of laparoscopy.

Harmonic scalpel in transanal microsurgery.

Background/aims: Retrospective clinical study of patients with rectal tumors treated by transanal endoscopic microsurgery (TEM) using Ultracision.

Methods: From 1997-2006 54 patients were treated by excision of the rectal tumors situated in the middle and distal portion, using the harmonic scalpel. We treated 25 male (range 40-76 years) and 29 female (range 46-80 years) patients.

Acute appendicitis and ileal perforation with a toothpick treated by laparoscopy.

A 69-year-old man underwent an emergency laparoscopic procedure after the acute appendicitis diagnosis has been established. Laparoscopic exploration showed inflamed appendix and perforation of terminal ileum with a swallowed part of the wooden toothpick. The treatment consisted of typical laparoscopic appendectomy and laparoscopic removal of the foreign body, followed by laparoscopic closure of the perforation site and lavage of the abdominal cavity.

Laparoscopic colon surgery: our results.

Formerly, the laparoscopic surgery was accepted as a method of choice for benign diseases, and for palliative operations in progressive stages of malignant diseases of the colon. Today, the laparoscopic surgery of the colon has been also adopted in treating malignant diseases. The first laparoscopic colon resection was performed in our Clinic on December 12, 2002, and 114 patients have been successfully operated until June 1, 2007.

A novel algorithm for the minimal invasive treatment of choledocholithiasis.

Background/aims: Laparoscopic cholecystectomy is the gold standard in choledocholithiasis treatment. Currently there is no generally accepted algorithm for choledocholithiasis treatment. A few years ago suspected or diagnosed choledocholithiasis was indication for open operation if bilious stones could not be removed with therapeutic endoscopic retrograde cholangiopancreatography (ERCP).

Partial cecal necrosis treated by laparoscopic partial cecal resection.

Acute colonic ischemia is the common cause of colitis in elderly population. However, isolated ischemic necrosis of cecum is rare entity, often associated with variety of conditions. Here we present a case of a 73-year old woman with a past history of hypertension presented with clinical symptoms of right lower quadrant abdominal pain and tenderness localized to the right lower quadrant, guarding and rebound tenderness.

Laparoscopic abdominal cysts fenestration using harmonic scalpel.

The use of ultrasonically activated scalpel for tissue cutting and coagulation is a potential replacement for electrosurgery, which can be related to different complications. Its working principle is to transform the electric power into the mechanical longitudinal movement of the working part of the instrument, by a piezoelectric transducer situated in the hand piece. Between October 2000 and June 2004, six patients with abdominal cysts were treated by laparoscopy, using the harmonic scalpel.
