Impact of body mass index, age and varicocele on reproductive hormone profile from elderly men.

OBJECTIVES: To study the impact of obesity, age and varicocele on sexual hormones of adult and elderly men. MATERIALS AND METHODS: 875 men who were screened for prostate cancer were enrolled in this study. Data recorded comprised age, body mass index (BMI), serum levels of total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH) and follicular stimulating hormone (FSH). Patients were divided in groups according to their BMI in underweight, normal weight, overweight and obese grades 1, 2 or 3. First, it was studied the association between age, BMI, and hormone profile. Then, clinical varicocele was evaluated in 298 patients to assess its correlation to the others parameters. RESULTS: Obese patients had lower levels of TT, FT and SHBG (p<0.001) compared to underweight or normal weight patients. There were no differences in age (p=0.113), FSH serum levels (p=0.863) and LH serum levels (p=0.218) between obese and non-obese patients. Obese grade 3 had lower levels of TT and FT compared to obese grade 1 and 2 (p<0.05). There was no difference in the SHBG levels (p=0.120) among obese patients. There was no association between varicocele and BMI; and varicocele did not impact on testosterone or SHBG levels. CONCLUSIONS: Men with higher BMI have a lower serum level of TT, FT and SHBG. The presence of clinical varicocele as well as its grade has no impact on hormone profile in elderly men.

[Magnetic resonance and traditional radiology in the spine localizations of alkaptonuric ochronotic arthropathy]. / Risonanza magnetica e radiologia tradizionale nelle localizzazioni vertebrali dell'artropatia ocronotica alcaptonurica.

AIM: To study the spine alterations in alcaptonuria with traditional radiology and magnetic resonance (MR), comparing the results of the two techniques. PATIENTS AND METHODS: Five patients (4 males, 1 female, mean age 51 years) underwent the examinations. For the study with X-rays we performed anteroposterior and lateral scan and the images have been studied making reference to a radiographic score; it examines the alterations of the joint space and the presence of calcifications. MR scan, oriented in the three spatial planes, were performed using spin echo T1-weighted and spin echo T2-weighted sequences. RESULTS: Both MR and X-rays pointed out, in the cases with known diagnosis, the typical alterations of the ochronosis: narrowing of the articular spaces, even osseous ankylosis, calcifications of the discs, osteophytosis, multiple disc protrusions and reactive sclerosis of the articular surfaces, evident above all to dorso-lumbar tract; nevertheless MR has been more accurate than X-rays for individualizing the lesions and recognizing alterations, such as the thickness of the anterior longitudinal ligament. In the case of new diagnosis, the MR is fundamental to recognize typical signs of the ochronotic arthropathy not well detected by X-rays. CONCLUSIONS: Imaging techniques, first of all the MR, are essential in the differential diagnosis of ochronosis vertebral lesions with other articular diseases.

A case report of osteochondroma of the frontotemporosphenoidal suture.

Osteochondroma, also known as osteocartilaginous exostosis, is the most frequent benign bone tumour of the skeletal system. Despite its preference for long bones (tibia and femur), osteochondroma may occur in some short bones developing endochondral ossification. Seventy-five percent of the patients present only with a single lesion, whereas 25% have multiple lesions; this last clinical condition, defined as osteochondromatosis (disorder of autosomal dominant inheritance) shows a high risk of malignant transformation (about 11%). In the craniofacial area this tumour is very rare. The sites of predilection are the coronoid process and mandibular condyle, even though osteochondromas arising from the base of the skull, maxillary sinus and zygomatic arch have been previously described. However, an osteochondroma originating from the frontotemporosphenoidal suture has not been reported before in the literature. We present a unique case of osteochondroma of the frontotemporosphenoidal suture. Moreover, the relevant international literature has been reviewed and all diagnostic and surgical matters have been discussed.

Parotid gland cancer: a case report of a primitive adenocarcinoma arising from a multirecurrent pleomorphic adenoma.

Parotid tumours represent a wide group of tumours which are mostly localized in the major salivary glands. We report a case of a 69-year old female with a parotid tumour history who was referred to us with a prominent lump and swelling localized in the right parotid area. In the period between 1985-2002, she was operated 5 times elsewhere for a recurrent pleomorphic adenoma of the right parotid (mixed tumour until 1991), which was histologically confirmed. Sixteen years after the primitive tumour, she underwent mastectomy and axillary dissection for a ductal carcinoma. Routine follow-up has been conducted on both malignancies. Pleomorphic adenoma is the most frequent tumour of the parotid. The potential risk of a malignant transformation can increase over the years with an incidence of 1% to 7%. Management of these recurrences is complex and controversial because of the different treatment options advocated such as radical resection with possible facial nerve sacrifice, or postoperative radiotherapy in non radical cases.

The role of Echo Colour/Power Doppler and magnetic resonance in expansive parotid lesions.

The purpose of this research was to evaluate the role of Echo Colour/Power Doppler and Magnetic Resonance Imaging (MRI) in the diagnosis of expansive parotid lesions, and to establish criteria for differential diagnosis between benign and malignant forms. Forty nine patients (23 males and 26 females), aging from 30 to 85 years, with an expansive pathology of parotid gland were enrolled in our study from February 1999 through August 2004. Each patient was carefully assessed employing both ultrasonography integrated with Color/Power Doppler and MRI. Eventually, all patients received echo-guided needle-biopsy and surgical excision of the parotid lesion. Preliminary ultrasound assessed site, size, echoic appearance and margins of the lesion. In order to assess blood supply by means of Colour/Power Doppler, we divided the patients in four groups. Our MRI diagnostic criteria included site, size, intensity of signal, behaviour of the lesion after i.v. contrast, relationship with facial nerve and retromandibular vein, detection of margins and proximity to adjacent structures. On the basis of our results, the Authors concluded that both Echo Colour/Power Doppler and MRI play a very important role in the diagnosis and surgical planning of parotid gland lesions.

Correction of hypospadias with a vertical preputial island flap: the Göteborg experience of 47 patients.

We report the follow-up of 47 patients with penile hypospadias who were treated by the Scuderi procedure between 1988 and 1998 at Sahlgrenska University Hospital, Göteborg, Sweden. Forty of the patients (85%) had had no previous operations, while the remaining seven had had meatotomy with chordectomy only, or an unsuccessful Dennis-Browne procedure. Hypospadias was distal in 35 (74%), mediopenile in 8 (17%), and proximal in 4 (9%); 21 (45%) showed signs of curvature. After a Scuderi urethroplasty one patient developed a fistula (2%) and 4 developed mild stenosis. The early success rate was therefore 42/47 (89%) and this later increased to 46/47 (98%) after non-surgical treatment of the stenoses. The results support the use of the Scuderi procedure for correction of primary and secondary penile hypospadias with a low complication rate.

Pleomorphic adenoma of the minor salivary glands of the palate.

A retrospective test was carried out on a sample of 11 patients, 8 women and 3 men, suffering from pleomorphic adenoma of the minor salivary glands of the palate. These sample patients were treated at the Department of Maxillofacial Surgery at the University of Rome "La Sapienza" between 1/1/90 and 31/12/95. Some diagnostic methodologies have been analysed, such as incisional biopsy and instrumental research (X-ray Orthopantomography and CT of the maxillofacial district with and without contrast medium in axial and coronal projections), surgical techniques for the removal of the neoformation and techniques for an immediate reconstruction. The surgical treatment foresaw, during the same operation, removal of the neoformation, reconstruction of the resulting defect and complete restoration of functions and aesthetics. The patients of the examined sample underwent a 5-year follow-up, based on clinical examinations and instrumental research. No immediate or delayed postoperative complications were evident, nor recurrence of the neoplasia. The purpose of this assignment is to compare the results that transpired from the retrospective test with those reported in the international bibliography.

Surgical treatment of recurrences of pleomorphic adenoma of the parotid gland.

From 1989 to 1999 a retrospective study was conducted on 7 patients with recurrent pleomorphic adenomas of the parotid gland who were referred to the MaxilloFacial Department of the University of Rome "La Sapienza" after having undergone surgery elsewhere. The mean time interval between the first operation and recurrences ranged from 15 months to 13 years, and the average time interval was 7.7 years. Implantability of the lesion and inadequate surgery that produced rupture of tumour capsule and tumour cells bleeding into surrounding glandular parenchyma, were the reasons for tumour recurrence. The instrumental examinations used for planning the surgical treatment to be applied and for studying the relations of recurrence with glandular parenchyma were CT (with contrast medium) or MR of head and neck. These patients underwent total parotidectomy with facial nerve preservation and no recurrence occurred in any patient. The results of this study underscore the importance of adequate surgical excision of initial recurrences as well as primary tumours to prevent tumour recidivism. Finally, tumour control rates and facial nerve preservation are enhanced with formal parotidectomy for recurrent tumour when feasible.

Surgical approach to non-small cell lung cancer involving the chest wall.

Treatment of NSCLC invading the chest wall (T3) remains controversial. Surgery is undoubtedly the only chance for these neoplasms, but its role regarding the T3N2 tumors is highly questionable. Between 1975 and 1994, 710 NSCLC patients underwent surgery in our department. Of these, 38 with tumor involvement of the chest wall underwent curative resection: en bloc resection or extrapleural resection, and 31 of these patients (19 with T3N0 tumors and 12 with T3N1-N2 tumors) were available for estimating long-term survival. The overall survival was 20.5% at 5 years and 15.4% at 10 years. Patients without lymph-node involvement had a survival rate of 26.2% at 5 years and 19.27% at 10 years. No patient with T3N2 tumor was alive 5 years after surgery. Patients with T3N1 tumor had a survival rate of 16.7% at both 5 and 10 years. The difference between T3N0 and T3N2 tumors was statistically significant. Neither histologic type nor depth of chest wall involvement had a significant impact on survival. En bloc or extrapleural resection, if curative, can be effective in T3N0-N1 tumors. Surgery is inadequate for the treatment of T3N2 tumors with chest wall involvement.

Vitiligo, autoimmune thyroiditis: a rare thyroid cancer arising with bone metastates on maxillofacial area.

An association between vitiligo and autoimmune thyroid disorders had previously been postulated. Thyroid disorders were found in 18.5% of 15,126 patients with vitiligo, on the basis of the anamnestic data. Then, we investigated 255 healthy relatives in whom we tested only T3, T4 and TSH. With the immunological investigation we detected a higher incidence of TMA in vitiligo patients and in the family members. Therefore, on the basis of the immunologic and thyroid pathology functional data, we observed a thyroid pathology in 25% of the 890 vitiligo patients and in 21.1% of their first degree relatives. Then, clinical observation enabled to discover that 3 of 15,126 patients had undergone exeresis for a thyroid carcinoma and in the 890 vitiligo patients, who had undergone particular investigations, we found a thyroid carcinoma in 3 subjects. In one case lymphnodal involvement and bone metastases in the maxillary district were found. The purpose of this work is to evaluate the incidence of thyrosis and of thyroid carcinoma in vitiligo patients observed for 20 years.

Facial nerve functionality after parotid tumors surgery.

The purpose of this study is to show the connection among tumor histology, surgical treatments and facial nerve postoperative functionality. A retrospective review was conducted on 69 patients with benign and malignant parotid tumors: they underwent surgical treatment for benign and malignant parotid tumors at the Maxillofacial Division of Rome University "La Sapienza" from 1988 to 1997. In our series of patients, we performed conservative superficial parotidectomy, conservative total parotidectomy and radical parotidectomy. Tumor enucleation was reserved for those neoplasms with a limited and restricted mass. The surgical approach was based on mass extension and on histopathologic features. Our findings showed that a careful and a timely diagnosis is very important in order to select a conservative surgical treatment for benign and intermediate grade of malignancy tumors with limited dimensions. Most aggressive histological types, and large mass dimensions require a radical treatment with consequent facial nerve postoperative dysfunctions. Our experience demonstrates that this surgical approach provides a very high rate of success in the cure of tumors and a low rate of facial nerve postoperative dysfunctions.

Pericardial cysts of the mediastinum.

Pericardial cysts are an uncommon benign disease. Their treatment, in the past, was based on excision by thoracotomy or, in selected cases, on percutaneous aspiration. The progress of video-assisted thoracoscopy gave new possibilities, but most surgeons still consider the thoracotomic approach as the treatment of choice. The aim of this study is to report our experience and to discuss the role of different therapeutic procedures in the management of pericardial cysts. Between 1970 and 1996, 24 patients with pericardial cysts were treated at the first Department of Surgery of the University of Rome <>. Of 24 cysts, six were located in the right cardiophrenic angle, three in the left cardiophrenic angle, two in the subcarenal areas, one in the paracardiac area and one on the posterior mediastinum. Ten patients were asymptomatic. Diagnosis was performed preoperatively only in patients with cysts typically located in the cardiophrenic angle. Twenty-three patients were surgically treated by a standard posterolateral thoracotomy or limited thoracotomy with sparing of muscles. One patient underwent CT-guided transparietal fine-needle aspiration. There were no cases of operative mortality. Morbidity was 12.5% and consisted of retained secretions, moderate hypoxemia and partial atelectasis. All patients were submitted to a long-term follow-up and no cyst recurrences were found. We conclude that excision via thoracotomy is an optimal treatment for pericardial cysts. Limited thoracotomy with sparing muscles offers a good cosmetic result and a rapid functional respiratory recovery. Percutaneous cyst aspiration may be, in selected patients, an attractive alternative to surgery.

[Maxillofacial fractures in children]. / Le fratture maxillofacciali nei pazienti in età di crescita.

BACKGROUND: Facial traumas in the younger population involve esthetic and functional matters. According to the international bibliography these problems are due to the fixation technique employed and to a delayed surgical treatment. METHODS: This article contains a list of 68 pediatric facial fractures treated at the Maxillofacial Department of the University of Rome "La Sapienza" including diagnosis and therapy over a period of 16 years (January 1981-October 1997). RESULTS: The results of this research show that the ability to treat such traumas is based on the early and careful identification of the fracture and on the choice of the best therapy to carry out according to the patient's age and with the fracture site pattern. RIF fixation is good to obtain healing in adults, but it may be responsible of disturbances in bone tissues growth. Hence, it was used in selected cases only, in order to avoid bone growth restriction as stressed in international bibliography. CONCLUSIONS: A delayed surgical repair of pediatric facial fractures does not guarantee the return to a correct functionally and to an appropriate esthetic feature.

[Pericardial cysts. Report on 9 treated cases]. / Le cisti pericardiche. Considerazioni su 9 casi trattati.

From 1976 to 1993, nine patients (5 men, 4 women) with pericardial cysts were treated in Authors' Department. Of the nine cysts, six were located in the right cardiophrenic angle, one in the subcarinal site, one in the right tracheobronchial angle, and one in the para-auricular site just above the diaphragm. Four patients were asymptomatic. A correct diagnosis was possible preoperatively only in patients with cysts typically located in the cardiophrenic angle. Eight patients were surgically treated by a standard posterolateral or axillary thoracotomy. One patient with a large pericardial cyst underwent needle percutaneous aspiration and CT-guided drainage of the cyst with a positive outcome. There was no operative morbidity or mortality.
