Role of elastosonography in the differentiation between benign and malignant neoformations of the breast and possibility of reducing the number of FNACS for tissue characterization.

INTRODUCTION: Background The aim of the paper is related to our experience defining the diagnostic accuracy of breast elastosonog-raphy. OBJECTIVE: The aim of our study is therefore to define the diagnostic accuracy of breast elastosonography in the differential diagnosis of nodular breast neoformations to improve the characterization of the solid lesion and reduce the number of needle aspiration unnecessary for benign formations. MATERIAL AND METHODS: A total of 88 patients were enrolled, who came to the Department with an ultrasound diagnosis of a breast lesion. Each lesion was subjected to mammography and B-mode ultrasonogra-phy with an evaluation of size, echogenicity, and vascularization pres-ence or absence. The use of the ultrasound machine and the respective probe has made it possible to make the measurements. All nodules were subjected to ultrasound-guided FNAC. These data were compared with the results of elastosonographic examination. RESULTS: FNAC results were as follows: CIN 1 in 18 nodules, CIN 2 in 22 nodules, CIN 3 in 36 nodules, CIN 4 in 6 nodules, and CIN 5 in 6 nodules. The sensitivity and specificity of elastosonography found in our case series reported values in line with data reported in the literature, confirming the method's high reliability. CONCLUSIONS: The elastosonography could become a complemen-tary technique to mammography and ultrasonography in the future, reducing the costs and risks of additional examinations. Therefore, we believe it is essential to contribute with this additional finding to increasingly accredit this pathway and reduce the discomfort to patients of more invasive methods.

Unusual presentation of metastatic thyroid cancer without a primary: role of diagnostic imaging in a daily clinical setting.

Papillary thyroid carcinoma (PTC) is the most common mali gnancy of the thyroid gland. In 21-90% of the patients occult lymph node metastases may occur. The case reported here describes a woman who underwent a total thyroidectomy for multinodular goiter and who presented an enlarged lymph node on the left side of the neck, which showed a metastasis from PTC. The patient underwent imaging investigation with CT and FNAB. The pathological examination diagnosed a papillary thyroid cancer metastases. The pT underwent a I131 total body scan, negative for secondary localization.

Densitometric changes of the patella in patients undergoing unilateral knee arthroplasty.

INTRODUCTION: Although the intervention of knee arthroplasty became routine, there is no standard reference on the densitometric characteristics of the patella before and after surgery. Scope of this work is the evaluation of patellar bone density before and after unilateral knee arthroplasty. PATIENTS AND METHODS: BMD was assessed by DEXA examination in 146 individuals, who have been divided into three distinct groups. Group I: 68 subjects with a mean age of 70.6 years, with an unilateral femoral-tibial knee prothesis. Group II: healthy subjects of similar age (average: 64) and without implants. Group III: healthy adults with a mean age of 26.6 years. The follow-up was performed at 6 months to a maximum of 2 years post surgery. RESULTS: The results were obtained from 68 subjects examined with the DEXA software dedicated to the forearm, which turned out to be the most appropriate for our purpose. The follow-up performed every 6 months after surgery showed a reduction of the density values in the operated knee in the 1st control with a return to the pre-surgiucal situation in the control performed after 1 year. In subsequent checks there was a further increase of the patellar density of the operated knee. CONCLUSION: Patellar DEXA examination is recommended as an addition to the clinical and radiological standard examination.

Choosing the individual rehabilitation program for patients with intermittent claudication.

This study is aimed at identifying the collateral circulation in case of femoral-aorta-iliac axis obstruction, with the purpose of a more correct therapeutic indication being either medical or surgical or physiotherapeutic or combined.

Pancreas divisum: correlation between anatomical abnormalities and bile precipitation in the gallbladder in seven patients.

Pancreas divisum is a genetic defect associated with recurrent acute pancreatitis due to insufficient drainage of the accessory pancreatic duct. Seven young patients diagnosed with pancreatic divisum and thickening of the gallbladder bile as shown on magnetic resonance cholangio-pancreatography without pancreatic ductal changes underwent laparoscopic cholecystectomy. During the mean follow-up of 32 months no episode of pancreatitis was reported. There is an association between PD and higher concentration of bile in the gallbladder. Cholecystectomy can be considered curative in patients with PD in the absence of indications for major surgery.

Deep vein thrombosis of the lower limb secondary to lumbar discal hernia compression: a rarity? Review of the literature.

This case report is about a 70-years-old female patient, suffering from discal hernia, with compression of the iliac vein, that led to the formation of deep vein thrombosis of the lower limbs. The angio-CT scan revealed the starting point of the L4- L5 compression where a voluminous discal hernia caused deep vein thrombosis, with the involvement the femoro-popliteal venous axis. Blood samples and PET-CT scans excluded other possible etiologic factors. This case demonstrates how a voluminous discal hernia can cause venous thrombosis.

Curative gastric resection for the elderly patients suffering from gastric cancer.

The improvement of the socio-economic conditions and the progress of medicine have extended the life span of the world's population and as a result, the number of patients with malignant neoplasms has increased. Gastric cancer is the third most common cancer (after lung and prostate) and the second leading cause of death caused by cancer (after lung bronchogenic cell carcinoma) in males; while it's the fifth cancer by frequency and the fourth cause of cancer death in females. It presents a peculiar geographical distribution with a lower incidence in Western Europe and North America, and higher incidence in the Far East, South America and Eastern Europe. Its incidence in Italy is 122 cases per 100000 inhabitants in males and 83 cases per 100000 inhabitants in females (in Italy). It occurs more frequently in old age, is quite rare in individuals under the age of 45. The aim of this work is to analyze the clinical and pathological characteristics of gastric carcinoma and the feasibility of curative surgery in patients over 75, identifying the factors affecting mortality, morbidity, survival and quality of life after surgery. These data have been compared with those of younger patients to assess the correct type of surgery.

Insulin-like growth factor-I (IGF-1), IGF-binding protein-3 (IGFBP-3) and mammographic features.

INTRODUCTION: 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. PATIENTS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Severity in biliary peritonitis.

OBJECTIVE: 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. RESULTS: 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). CONCLUSIONS: 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.

[Phlegmons of the neck: our experience with 7 cases]. / Flemmoni del collo: nostra esperienza su 7 casi clinici.

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.

Immunohistochemical expression of fatty acid synthase, Ki-67 and p53 in squamous cell carcinomas of the larynx.

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.

[Monolateral adenopathy of the axilla due to sarcoid-type granulomata: idiopathic granulomatous disease or sarcoidosis? A case report]. / Linfoadenopatie ascellari monolaterali da granulomi di tipo sarcoidosico: malattia granulomatosa idiopatica o sarcoidosi? Caso clinico.

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.

[A case of recurrent pharyngocele: treatment and literature review]. / Un caso di faringocele bilaterale recidivato come mediano e rioperato con successo.

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.

[A case of lymphoepithelial cyst (branchial cyst) in an elderly patient: diagnosis differential, treatment and literature review]. / Un caso di cisti linfoepiteliale (branchiale) in un paziente anziano: diagnosi differenziale, trattamento e revisione della letteratura.

We present a case of lateral cervical cyst stressing the difficulties about the diagnosis. The international guidelines for the management of lateral neck cysts in the over 40s' age group are taken in consideration. Our case is a 74 years old male patient with a 6 month history of a cervical swelling. We consider this case rare for the age of patient and the absence of malignancy.

Early diagnosis of endolymphatic hydrops with distortion. Product otoacoustic emissions.

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.

Transit time of swallowing after subtotal laryngectomy.

INTRODUCTION: 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). MATERIALS AND METHODS: 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. RESULTS: The results consistently showed that swallowing time remains under one second as in individuals with normal swallowing functions. CONCLUSION: 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.
