No full textAbstract
Two cases of oxyuriasis of the appendix observed out of 870 cases of acute appendicitis are presented. Our aim was to examine the incidence of such condition and to correlate personal experience with data from the current literature. In personal experience, the incidence of pinworm appendicitis is low (0.22%) in line with a generalized decrease of oxyuriasis infestation. Such data is even more significant if we take into account that it is observed in a rural area. Of course we can confirm the presence, although rarely, of the pin-worm in the appendix but whether or not the parasite is cause of a true acute appendicitis is still matter of debate. Symptoms of our patients and signs on physical examination were those of typical acute appendicitis. Finally, treatment of such cases could not be represented merely by appendectomy, but antihelminthic therapy should be instituted in order to eradicate the parasite from the intestine of the patient as well as from parents since reinfection is frequent
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Mesh repair of inguinal and femoral hernia [Chirurgia protesica delle ernie inguinali e crurali.]
No full textAbstract
The authors describe a 6-year experience with mesh repair of inguinal and femoral hernia in a surgical teaching department. Two hundred and ninety-seven hernioplasties were performed in 256 consecutive patients: 237 Trabucco sutureless and 11 Lichtenstein tension-free hernioplasties for inguinal hernia; 21 tension-free hernioplasties for femoral hernia; 20 Wantz GPRVS and 8 Rutkow tension-free hernioplaties for recurrences. Local anaesthesia was used in 59% of cases. Seventy-two patients (28.1%) refused this type of anaesthesia. The hospital stay was two days in all cases. The local postoperative morbidity rate was 8.7% (wound infections: 1.0%; neuralgia: 1.3%; haematomas: 2.0%; seromas: 2.3%; no testicular atrophies). The recurrence rate was 1.9% in the group of patients undergoing surgery from 1994 to 1997 (103 herniorrhaphies; follow-up: 3-6 years) and 0% in the group of patients operated on after 1997 (170 herniorrhaphies; follow-up: 2 years-6 months). The results confirm that the use of a prosthetic mesh (patch and plug) is the treatment of choice for hernia repair. Moreover, this experience in a surgical teaching department shows that these procedures can be safely and effectively performed by all surgeon
Blood levels of cholesterol and postoperative septic complications [Livelli ematici del colesterolo e complicanze settiche postoperatorie.]
No full textAbstract
Hypocholesterolemia seems to represent a significant predictive factor of morbidity and mortality in critically ill patients. The authors, on the basis of recent literature data, aim to clarify the possible correlation between preoperative hypocholesterolemia and the risk of septic postoperative complications .205 patients undergoing to surgery for gastrointestinal diseases were the object of the study. Patients undergoing "minor" abdominal surgery or video-laparoscopic surgery and classified ASA III-IV were excluded. In all the patients, we considered retrospectively risk factors for postoperative septic complications as follows: preoperative blood concentration of cholesterol, malnutrition, obesity, diabetes, neoplasm, preoperative sepsis, type and duration of operations, antibiotics and regimen of use. Type and incidence of postoperative local or systemic septic complications were recorded. The patients have been stratified according to blood concentration of cholesterol and to the presence or absence of other risk factors. The incidence of postoperative sepsis was 35.1%. The highest incidence of postoperative septic complications (72.7%) was encountered, significantly (X2 = 7.6, p < 0.001), in the patients (11 cases, 5.9%) with cholesterol levels below 105 mg/dl). The results of this study seems to indicate a significant relationship between preoperative hypocholesterolemia and the incidence of septic complications after surgery. Moreover, evaluation of blood cholesterol levels before major surgery might represent a predictive factor of septic risk in the postoperative period
