ABSTRACT: To analyze clinical and laboratory findings in order to find variables predictive of severity of Biliary Peritonitis (BP). Patients and methods. Physical findings, course of illness, imaging and laboratory data were evaluated in 42 patients with BP, and statistically analysed to assess their prognostic significance.
Serious illness and worse outcome were associated with: age ≥ 60 years (P=0.034), long time between onset of symptoms and treatment (P=0.025), fever > 38°C (P=0.009), WBC count > 17,000 cell/mm³ (P=0.043), diffuse abdominal pain (P=0.034), and infected bile (P=0.048).
Most patients become severely ill due to supervening infection, while early bile drainage avoids serious complications. In addition, abdominal pain, fever and WBC count are also predictive of severity of BP.

ABSTRACT: The IGF system has recently been shown to play an important role in the regulation of breast tumor cell proliferation. However, also breast density is currently considered as the strongest breast cancer risk factor. It is not yet clear whether these factors are interrelated and if and how they are influenced by menopausal status. The purpose of this study was to examine the possible effects of IGF-1 and IGFBP-3 and IGF-1/IGFBP-3 molar ratio on mammographic density stratified by menopausal status.
A group of 341 Italian women were interviewed to collect the following data: family history of breast cancer, reproductive and menstrual factors, breast biopsies, previous administration of hormonal contraceptive therapy, hormone replacement therapy (HRT) in menopause and lifestyle information. A blood sample was drawn for determination of IGF-1, IGFBP-3 levels. IGF-1/ IGFBP-3 molar ratio was then calculated. On the basis of recent mammograms the women were divided into two groups: dense breast (DB) and non-dense breast (NDB). Student's t-test was employed to assess the association between breast density and plasma level of IGF-1, IGFBP-3 and molar ratio. To assess if this relationship was similar in subgroups of pre- and postmenopausal women, the study population was stratified by menopausal status and Student's t-test was performed. Finally, multivariate analysis was employed to evaluate if there were confounding factors that might influence the relationship between growth factors and breast density.
The analysis of the relationship between mammographic density and plasma level of IGF-1, IGFBP-3 and IGF-1/ IGFBP-3 molar ratio showed that IGF-1 levels and molar ratio varied in the two groups resulting in higher mean values in the DB group (IGF-1: 109.6 versus 96.6 ng/ml; p= 0.001 and molar ratio 29.4 versus 25.5 ng/ml; p= 0.001) whereas IGFBP-3 showed similar values in both groups (DB and NDB). Analysis of plasma level of IGF-1, IGFBP-3 and IGF-1/IGFBP-3 molar ratio compared to breast density after stratification of the study population by menopausal status (premenopausal and postmenopausal) showed that there was no association between the plasma of growth factors and breast density, neither in premenopausal nor in postmenopausal patients. Multivariate analysis showed that only nulliparity, premenopausal status and body mass index (BMI) are determinants of breast density.
Our study provides a strong evidence of a crude association between breast density and plasma levels of IGF-1 and molar ratio. On the basis of our results, it is reasonable to assume that the role of IGF-1 and molar ratio in the pathogenesis of breast cancer might be mediated through mammographic density. IGF-1 and molar ratio might thus increase the risk of cancer by increasing mammographic density.

ABSTRACT: Phlegmons of the neck originate from infectious diseases of head and neck. Odontogeneous inflammation of the oral cavity is most frquently primary lesion, followed by sinusitis, otitis, as well as radiation therapy and surgical procedures. Phlegmons of head and neck can drain into the spaces among the muscles, aponevrosis, organs inside the neck like sublingual space, lateral pharyngeal space, retro-pharyngeal space or pre-vertebral space. We hereby report our experience with 7 patients treated from 2001 to 2005.

ABSTRACT: The present investigation was specifically designed to evaluate the ability of the glycerol test combined with pure-tone audiometry, distortion-product otoacoustic emissions (DPOAEs) to diagnose endolymphatic hydrops early and to identify patients who may evolve toward Meniere's disease. This investigation consisted of 43 consecutive patients with daily episodes of tinnitus with duration exceeding few hours or with continuous tinnitus who received no treatment. These were the unique symptoms reported by the patients. Each patient underwent glycerol testing measured with conventional pure tone audiometry and with distortion product otoacoustic emissions (DPOAEs). For the traditional pure-tone glycerol test a hearing improvement of at least 10 dB, at the lower two or three frequencies (125,250 and 500 Hz) was judged as positive result. For the DPOAEs glycerol testing, a smaller positive difference (5 dB) for at least three frequencies was interpreted as a significant fluctuation. Twenty four patients showed negative glycerol test both with pure tone audiometry and DPOAEs. In 7 cases the improvement was concurrently observed. In 9 patients post-glycerol changes appeared only in the DPOAEs outcomes. Finally the remaining three patients had two different patterns. Two had different ameliorations of the DPOAEs and pure-audiometry on the left and right sides respectively, and in the last one only post-glycerol, audiograms recovered. The present study re-confirms the potentiality of DPOAEs associated with glycerol test in diagnosing endolymphatic hydrops precociously. The possibility of these patients degenerating into Meniere's disease should not be underestimated.

ABSTRACT: The aim of subtotal laryngeal surgery (Cricohyoidopexy = CHP and Cricohyoidoepiglottopexy = CHEP) is to create a simplified but functional neolarynx. The neolarynx permits the passage of air, the closure of the airway, and ensures phonation through the vibration of the cricoid and arytenoid mucosa; furthermore, it allows the recovery of swallowing, optimizing the closure of the neoglottis with the movement of the remaining arytenoids. The aim of the present study was to evaluate, on a long-term basis, the efficiency of the swallowing function comparing swallowing times in CHEP and CHP with and without functional neck dissection (FND).
A radiological study was conducted on 48 patients selected from a group of 253, who underwent subtotal laryngectomies at the "G. Ferreri" Department of Otorhinolaryngology, Audiology and Phoniatrics of the University of Rome "La Sapienza". The selection of the 48 patients was carried out based on the following criteria: type of surgery, date of surgery (follow up of at least 12 months), patients who were not treated with radiotherapy before or after surgery, patients who were also examined with fibrolaryngoscopy and videofluoroscopy, patients not affected by motor deficits involving phonatory and swallowing regions (stroke, lesions of the central nervous system), negative follow up (no evidence of disease). The parameters for evaluating the functional recovery were the times the nasogastric tube and tracheotomy tube were kept in place. The functional recovery times of the groups thus formed were compared to one another Through videofluoroscopy the authors evaluated oral transit times (OTT) and pharyngeal transit times (PTT) as parameters of deglutition.
The results consistently showed that swallowing time remains under one second as in individuals with normal swallowing functions.
The study of deglutition times, conducted at least 12 months after surgery, does not show any substantial differences between CHEP and CHP with reference to pharyngeal transit and oral transit times.

ABSTRACT: Fatty acid synthase (FAS) is a recently discovered molecule involved in the energy supply to normal cells. FAS is overexpressed in neoplastic tissues because of their increased energy needs. We explored the immunohistochemical expression of FAS, Ki-67 and p53 in squamous cell carcinomas (SCC) of the larynx and their association with clinicopathological features and outcome. Specimens from 43 patients with SCC were evaluated. Statistical analysis revealed an association between poorly differentiated laryngeal carcinomas and FAS expression (p<0.005) and between FAS and Ki-67 overexpression (p<0.001). Finally, FAS expression was associated with overall survival (p<0.001). We suggest that FAS is a powerful prognostic indicator whose strength can be enhanced when it is evaluated together with clinicopathological data and Ki-67 expression.

ABSTRACT: Congenital or acquired pharyngocele is a rare disease characterized by a herniation of the pharyngeal mucosa through a "locus minoris resistentiae" of the lateral wall of the pharynx. Generally the pharyngocele does not present specific clinical signs or symptoms which makes it necessary to resort to radiological examination for the diagnosis. Our case is particular for primitive bilaterality and the single and median recurrence eight years later. After surgical excision the symptoms completely disappeared. The radiological examinations following surgery were negative.

ABSTRACT: The presence of sarcoid-type granulomata in peripheral lymph nodes, with no evidence of other typical lesions, doesn't allow to diagnose sarcoidosis. In fact, sarcoidosis is a systemic disease and two or more organs must be affected to reach a definitive diagnosis. However this involvement could happen even several years later, thus making a correct diagnosis really difficult. In the absence of other organ involvement, an "idiopathic granulomatous disease" of peripheral lymph nodes is identified. Patients must anyway undergo a careful, long-term follow-up in order to detect clinical or radiologic variations that may confirm a diagnosis of sarcoidosis. After presenting a case-report of monolateral adenopathy of the axilla as an idiopathic granulomatous disease, the Authors review the international literature about sarcoidosis and its extra-pulmonar presentation, underlining the importance of considering sarcoidosis among possible diagnosis when peripheral adenopathies occur.
