Antibacterial Effects of Thermosonication Technology on Strains Identified from Swine Food Chain: An In Vitro Study.

Among innovative food technologies, ultrasounds have demonstrated physical damages (provided by frequency and intensity factors) on bacterial structures while determining the microbiological stabilization of many foodstuffs. This study tested the efficacy of the thermosonication process on 16 strains belonging to the academic biobank (isolated from swine slaughterhouses). All strains were exposed to focused ultrasounds, generated by the Waveco system (Milan, Italy), with the following settings: 40 KHz coupled with 80 W at different 5 min intervals starting from 5 to 15 ones, and focusing on two different temperatures: 40 °C and 50 °C.

Ultrasonic decontamination in smoked salmon experimentally contaminated with : Preliminary results.

The purpose of this work was to evaluate the effects of ultrasound (sonication) and their combination with temperature (thermosonication) on the inactivation of (LM) in smoked salmon. The trial was conducted on smoked salmon samples experimentally contaminated with a cocktail of 4 strains of (LM ATCC 19114, LM ATCC 15313, LM ATCC 19111 and LM ATCC 7644) at a final concentration of 8 log cfu/g and kept at 4°C until its use. Thermosonication treatments between 40°C and 50°C for 5, 10 and 15 minutes proved to be more effective without altering the sensory characteristics of the food.

Lack of vincristine infiltrates in patients with retinoblastoma receiving chemotherapy by peripheral intravenous lines.

The delivery route of chemotherapy for intraocular retinoblastoma has become controversial. One objection to systemic delivery is the need for central venous access. We cross-referenced a hospital vascular access database with our tumor registry to determine the incidence of chemotherapy infiltrates.

An experimental study of pain upon stimulation of the nasal and sinus cavities.

Objective: To map different areas of pain sensitivity and to determine the existence and/or pattern of referred pain from upon stimulating the sinonasal cavity.

Study Design: Experimental human study.

Methods: Mechanical and electrical stimulations to various anatomical structures and areas of the nasal and sinus cavities were conducted on nine volunteers.

The forgotten turbinate: the role of the superior turbinate in endoscopic sinus surgery.

The fate of the middle turbinate in endoscopic sinus surgery has been a subject of debate for some time. The superior turbinate's role, however, has been largely passed over. Past anatomic descriptions and illustrations have given surgeons the incorrect impression that this structure is well superior and out of the field of dissection.

Endoscopic sinonasal surgery in the management of primary headaches.

Primary headaches (migraine, cluster, tension-type) are common disorders thought to be unrelated to nasal and sinus abnormalities. We present data on 19 patients with refractory primary headaches in the absence of significant sinus symptoms. The majority of patients responded with decreased pain to office application of nasal anaesthesia.

[Laparoscopy: access with open versus closed technique].

Pneumoperitoneum in diagnostic or therapeutic laparoscopy can be achieved by an open or a closed technique. The authors, on the basis of their experience, compare both techniques, concluding that open method is safer, because of the lack of major complications observed in the closed method and with only few minor complications.

Pneumatized superior turbinate as a cause of referred migraine headache.

Three patients with typical (common) migraine unresponsive to conventional therapy were evaluated with complete otolaryngologic examination, diagnostic nasal endoscopy, and coronal sinus computed tomography (CT). Enlargement of the superior turbinate due to pneumatization, with accompanying mucosal contact, was found in each case. Application of topical or injected anesthetic to the superior turbinate lessened or relieved headache, and subsequent endoscopic sinonasal surgery succeeded in providing significant headache relief (follow-up of 6 to 14 months).

Sinus headaches reconsidered: referred cephalgia of rhinologic origin masquerading as refractory primary headaches.

Headache associated with acute sinusitis is a well-recognized entity; the diagnosis is easily made due to the associated nasal and sinus symptoms. However, the phenomenon of referred headache from chronic sinusitis or intranasal abnormalities or both without upper respiratory symptoms is not well understood. Only recently have the nasal and sinus cavities been adequately visualized by both the human eye and radiographic techniques; a fact that may account for the historic neglect in considering this region a factor in headache etiology.

[Hemorrhagic necrotic acute pancreatitis: analysis of our case series in the light of the most recent diagnostic and therapeutic criteria].

During the period between 1-1-1979 and 30-9-1992, 43 cases of hemorrhagic necrotic acute pancreatitis were referred to the authors' attention. Six patients were not operated, 12 underwent emergency surgery and laparotomy was postponed in 25 cases. The introduction of sophisticated diagnostic methods, such as Eco, CT, ERCP, intensive medical therapy and postoperative NPT have allowed a more rational surgical approach in terms of timing and extent to be adopted, operating on patients who are metabolically more stable.

Osteoma of the internal auditory canal. Case report and literature review.

Osteomas of the internal auditory canal are rare lesions, with only 12 reported cases in the world literature. Symptoms are those of eighth nerve compression, and include unilateral hearing loss and vestibular weakness, thus mimicking symptoms of acoustic neuroma. We report a patient with an osteoma of the internal auditory canal, along with a review of the literature.

Referred headache of rhinogenic origin in the absence of sinusitis.

Nasal signs and symptoms commonly accompany cephalgia in some headache syndromes. Head pain associated with sinusitis is also fairly well-recognized. However, referred cephalgia of rhinogenic origin, in the absence of sinonasal symptoms or disease, is poorly understood.

[Colorectal neoplasms in young patients].

The prognostic factors regarding colon-rectal cancers in the under-40s are examined. A personal series of 15 cases shows that the incidence of tumour recurrence is higher and the disease-free interval shorter than in patients not selected for age and that 5-year survival is much less. These results permit the hypothesis of greater aggressiveness in colorectal cancers in the young, something that justifies the severer prognosis by comparison with the elderly population.

[Our experience in tailoring definitive terminal colostomies and in the follow-up of such patients].

Between January 1983 and July 31, 1988 at the 1st Division of General Surgery of Cuneo S. Croce Hospital, 57 patients (33 m, 24 f) were subjected to abdomino-perineal amputation for rectal A.D.

[Acute mesenteric infarct. III. Therapeutic problems].

The treatment adopted in 11 cases of acute mesenteric infarction is described: 6 cases involved arterial occlusion due to embolism and 5 arterial occlusion due to thrombosis. Six explorative laparotomies, 4 intestinal resections and one embolectomy of the superior mesenteric artery were carried out. Mortality was 63%.

[Acute mesenteric infarct. II. Problems of early diagnosis].

The symptomatology and diagnostic procedure adopted in 11 cases of acute mesenteric infarction are examined. Stress is laid on the importance of early, aetiologically accurate diagnosis for the purpose of instituting profitable treatment. In order to comply with such needs it is essential to perform urgent selective arteriography and/or urgent laparoscopy which only with rare exceptions is carried out even in hospitals that should be better equipped.

[Acute mesenteric infarct. I. Identification of predisposing factors and definition of the criteria of "cautious clinical monitoring" of the main groups of patients at risk].

On the basis of experience acquired through 11 cases of acute mesenteric infarction personally observed over a 10-year period (1-1-1978-31-12-1987) and on the basis of a review on the literature, the usefulness for the purposes of early diagnosis and consequent early treatment of monitoring the essential, typical biological and clinical parameters of patients at risk of acute mesenteric infarction are reported.
