Neonatal umbilical cord blood transplantation halts skeletal disease progression in the murine model of MPS-I.

Umbilical cord blood (UCB) is a promising source of stem cells to use in early haematopoietic stem cell transplantation (HSCT) approaches for several genetic diseases that can be diagnosed at birth. Mucopolysaccharidosis type I (MPS-I) is a progressive multi-system disorder caused by deficiency of lysosomal enzyme α-L-iduronidase, and patients treated with allogeneic HSCT at the onset have improved outcome, suggesting to administer such therapy as early as possible. Given that the best characterized MPS-I murine model is an immunocompetent mouse, we here developed a transplantation system based on murine UCB.

[Pathophysiological and clinical trials of the abdominal compartment syndrome].

The abdominal compartment syndrome (ACS) is defined a situation of high degrade abdominal hypertension (IAH) with clinicals signs of multiorganic dysfunction. It's observed like in the intensive care, in particular surgycals and postraumatics, there is ever a bigger frequence of complications presented by criticals patients. The various trials remark a changeable incidence, but the common factor is characterized by a particular severity of scores.

[The femoral hernia: problems in emergency surgery].

The femoral hernia can be defined as infrequent, and predominantly found in females, with the highest incidence between 30 and 40 years of age. It shows a high tendency to strangulation, also up to 40% of cases, due to the presence of the Gimbernat ligament, which with its tense fibrous margins, aids strangling known as "raised crest". The diagnosis may not be easy, overall in the clinical presence of acute abdomen in elderly patients, disabled people or people who are uncooperative during physical examination.

[The surgical treatment of neoplastic colorectal occlusions].

The emergency treatment for neoplastic occlusions of rectum still needs debugging. While we finds perfect accord in to directly treat with a right hemicolectomy (more or less widened) the tumours from cecum to the first portion of the right colon, not the indications are likewise shared in presence of neoplastic stenosis of sigma-rectum. The treatment of urgency of these tumours is lent to so many variable and the tendencies too are constantly in evolution in relationship to the improvement of the technologies and the surgical devices.

[Colon lesion for blunt trauma in the abdomen].

Colon lesions resulting from blunt trauma in the abdomen can be defined as infrequent. Actually, they represent 3-5% of all hollow organ trauma. They present, however, serious social burden because of its prevalence in males with medium age ranging from 40 to 70 years.

Gastrointestinal surgical emergencies in patients treated for hemathological malignancies.

Background: Upper and lower gastrointestinal symptoms are major and serious complications in patients who undergo chemotherapy for hematological malignancies. Their most frequent causes are acute intestinal graft-versus-host disease (GVHD) after bone marrow transplant, infections, toxicity or preexisting gastrointestinal diseases. Mortality can reach 30-60% of cases.

[Acute appendicitis or diverticulitis of the right colon? Diagnostic dilemma in emergency surgery].

Diverticulitis of the right colon is a rare disease in the Western countries, so that the diagnosis still remains very difficult and frequently indistinguishable from acute appendicitis preoperatively. In presence of acute abdominal discomfort with pain referred to the right lower quadrant region, fever and hyperleukocytosis, nausea and vomiting, surgeons operate with a margin of uncertainty, because of the increased morbidity and mortality associated with delay in diagnosis and consequent perforation of acute appendicitis. Moreover the unexpected inflammatory colonic mass of uncertain etiology is sometimes mistaken for carcinoma at laparotomy and consequently a right hemicolectomy is performed.

[Abdominal compartment syndrome: patophysiologic and clinic remarks].

The abdominal compartment syndrome is a high grade abdominal hypertension with clinical evidence of multiorgan failure (MOF). It is more and more frequently observed in intensive-care units as a complication in critical patients, but especially in traumatology and surgery. The incidence is highly variable according to the different trials but the severity of scores is the common factor.

TNFa-based isolated hyperthermic limb perfusion (HILP) in the treatment of limb recurrent melanoma: update 16 years after its first clinical application.

Hyperthermic Limb Perfusion (HILP) with Tumor Necrosis Factor alpha (TNFalpha) and interferon gamma (IFNgamma) was pioneered by Liénard and Lejeune in 1988. TNFalpha was empirically employed at a dosage of 3-4 mg that is ten times the systemic maximum tolerated dose (MTD). Sixteen years after its first clinical application more than 300 patients have been treated and some clarifications can be made regarding three major questions: the real role of IFNgamma, the TNFalpha dose and eligibility criteria for patient selection.

[Traumatic lesions of the diaphragm].

The Authors studied 30 cases of diaphragmatic traumatisms from 1972 to 2003 to stress the difficulty to achieve an early diagnosis and the need of their immediate treatment: 26 of these patients were male and 4 female (6.5:1); the pathogenesis was in 50% of cases an open trauma and in 50% a closed trauma. The mean age was 36.

[Colonic perforations after self-expandable metallic stenting: two case reports].

The use of self-expandable metallic stents in colorectal stenoses, both benign and malignant, is a recently born treatment, quickly widespread because of its simplicity and therapeutic efficacy. It is particulary useful, like emergency temporany treatment, in malignant colonic obstruction; in these cases the temporary endoprosthesis positioning allows the intestinal transit and to overcame the emergengy phase. After patient conditions improvement, he can be operated and the endoprosthesis removed within operating specimen.

[Packing: current concepts of "life-saving" surgery].

Abdominal packing is a lifesaving technique for temporary control of severe injury and it is used in Damage Control Surgery schedule. Technically bleeding from abdominal cavity can generally be achieved by applying pressure with several large abdominal packs. It's possible too applying packs in organ-specific techniques (early abdominal packing).

[Small intestine tumors: our experience in emergencies].

Small bowel tumours are relatively rare neoplasms; unusual occurrence associated with nonspecific symptoms, and low-sensitivity tests availability, are responsible for diagnostic delay. A retrospective study was performed on 42 cases with acute presentation, from 1972 to 2001; median age was 52 years (range 14-79) and there was a slight female prevalence (57.1% vs 42.

[Peritoneal papillary serous carcinoma: clinical report].

Peritoneal papillary serous carcinoma (PPSC) is a rare tumour that involves the surface of the peritoneum, with prevalence in female patients and can originate from a single or multicentric focus is here described. A primary peritoneal serous carcinoma is here described. The patient has been treated with paclitaxel 175 mg/m2 and carboplatinum AUC 6.

[Difficult endoscopic extraction: pneumomediastinum and bilateral pneumothorax after attempted endoscopic extraction of needle incarcerated in hiatal hernia].

From June 1987 to April 2000, 167 (74%) of 223 patients suspected of swallowing foreign bodies were treated. Hundred-sixty-three were successfully treated endoscopically. The surgery rate was 2.

[Damage control surgery: the technique].

Abdominal packing and planned reoperation is a lifesaving technique for temporary control of haemorrhage in severely injured patients. Morbidity and mortality, however, remain significant. The purpose of this study is to evaluate all surgical technique and our results during 31 years of trauma surgery.

[Use of adhesives in emergency surgery].

In a prospective study, the Authors present an analysis on the use of surgical adhesives in the wounds treatment. In sixteen months we have treated 157 patients exclusively with a surgical tissue adhesive 2-octylcianoacrylate to repair traumatic wounds and surgical ones. In the Emergency Department were treated 110 patients (70%) with 2-octylcianoacrylate for skin incisions, lacerations and the length of lesion.
