Abstract
Introduction: An increasing interest exits towards the use of antibiotics in the treatment of uncomplicated acute appendicitis.Discussion: For a long period of time, surgery was the only treatment for acute appendicitis. Due to recent research in the etiology of acute appendicitis which seems to be driven by intraluminal bacterial proliferation, new data suggests that for non-perforated appendicitis confirmed with the help of CT, antibiotics may play a central role in the treatment. As relapse rates amount in some cases to only 5% after antibiotic treament, a discussion is required regarding the risks of interval appendectomy and its use. The debate regarding the optimal antibiotic course is on-going as some surgeons advocate for amoxicillin/clavulanic while others, due to acquired resistance recommend Ertapenem.Conclusion: Selective antibiotic treatment for selected forms of acute appendicitis, uncomplicated without perforation is safe and has a relatively low complication rate. However, certain mentions must be made: surgery must not be delayed if failure of antibiotics exists as it can lead to higher rates of peritonitis. Close clinical surveillance is of utmost importance

Abstract
Abstract : Neuroendocrine tumors represent a varied group of neoplasms which have the potential to produce and secrete a wide range of hormones along with other vasoactive substances.The care of these patients involves several specialties including:surgery, oncology, radiotherapy, interventional radiology and nuclear oncology. Despite this large number of options there is currently no consensus on the optimal sequence of these treatment resources for metastatic patients.We present the case of a 24 year women who was diagnosed with a gastric tumor (could not be biopsied) by imagistics and liver metastatsis. A Pean resection with metastasectomy was done. The histopathology study revealed that the gastric tumor was benign ectopic pancreas tissue and the metastases were actualle of neuroendocrine origin. A somatostatin receptor scintigraphy (OctreoScan) was done which revealed the primary tumor in the ileal mesentery which was resected in a secondary intervention. The patient was started on long acting sandostatin with no recurence.

Abstract
Sexual dysfunction following surgery for rectal cancer may be frequent and often severe. The aim of the present study is to evaluate the postoperative incidence of this complication and its severity. The current study is a retrospective study in which consecutive patients with rectal tumors, regardless of location (upper, middle or lower) were enrolled during a 1 year period in the General Surgery Clinic of the Emergency Clinical Hospital Prof. Dr. Agrippa Ionescu, Hospital, Bucharest. The patient files, paraclinical investigations, operative protocols, and histopathological bulletins were reviewed and data regarding age, gender, date of diagnosis, medical treatment administered including neoadjuvant therapy and reinterventions were collected. The IIEF-5 type questionnaires were used to assess sexual function at 6 months. We identified a number of 30 patients with amedian age of 60 years. All the patients were operated via open approach. Total mesorectal resection (TME) was practiced in 18 cases. Mean period follow-up was 10 months. Perioperative mortality was 0. There was no recurrence 1 year after surgery. Ten patients benefited from neoadjuvant radiotherapy. Rate of erectile dysfunction was 80%. The rate of ejaculation dysfunction was 70%. Patients operated for rectal cancer via an open approach showed severe sexual dysfunctions (SD). These complications affect the patient’s quality of life and need a multidisciplinary approach towards a better understanding of this problem by both the medical staff and the patient.

Abstract
After more than 20 years from the beginning of laparoscopic surgery, laparoscopic cholecystectomy still holds a conversion rate of 5.1 % in the specialty literature. We have conducted a retrospective study based on the experience of the clinical unit of General Surgery within “Prof. Dr. A. Ionescu” Emergency Clinical Hospital, between 1997 and 2013. A number of 2,309 laparoscopic cholecystectomies were performed. The average age of the group was 47.3 years. Conversion was performed to a number of 58 patients (2.51%), out of which 74.13% women (no. = 43) and 26% men (no. 15). The average age of the patients to whom the conversion was performed was 57. Conversion to open cholecystectomy was more frequent in patients over 60 (no. 38). The main preoperative diagnosis in converted patients was acute lithiasic cholecystitis. Laparoscopic cholecystectomy is a safe method with optimal results, being considered the “gold standard” in the treatment of bladder lithiasis. Conversion to open surgery is an expression of the surgeon’s experience and wisdom.

Abstract
PURPOSE Aim of this study is focusing on bone metabolism in AN patients with amenorrhoea and related estrogen deficiency effects. METHODS AN patients were compared both with healthy females and with postmenopausal women (reference model for estrogen deficiency). The study sample included 81 females with AN. Laboratory tests [25-OH vitamin D, bone turnover markers, intact parathyroid hormone, sclerostin (SOST) and dickkopf-related protein (DKK1)] and dual energy X-ray absorptiometry (DXA) were taken into account. RESULTS AN patients had higher levels of C-terminal telopeptide of type I collagen (CTX) than both control groups. AN adolescents had CTX higher than AN young adults. In postmenopausal women, intact N-propeptide of type I collagen was higher if compared with each other group. In AN groups, Dickkopf-related protein 1 was significantly lower than the two control groups. No differences were found in sclerostin except in adolescents. In AN adolescents, DXA values at femoral sites were higher than in AN young adults and a positive correlation was found with body weight (p < 0.01) and with fat mass evaluated using DXA (p < 0.01). CONCLUSIONS AN women with amenorrhoea have an increased bone resorption like postmenopausal women but bone formation is depressed. The consequent remodeling uncoupling is considerably more severe than that occurring after menopause.

Abstract
UNLABELLED Several therapies are available for osteoporis. Understanding the bone turnover changes and their mutual realtionship gives an overall view and might lead to a target therapy INTRODUCTION: The aim of this study is to compare the changes in bone turnover markers in patients treated with either denosumab alone, teriparatide (TPTD) alone, or in a third therapeutic scheme, when TPTD was added to patients previously treated with denosumab. METHODS Fifty-nine women over 65 years old with severe postmenopausal osteoporosis (evidence of at least two moderate-severe vertebral fractures) were enrolled in the study. Serum samples were collected every 3 months. They were assayed for intact N-propeptide of type I collagen (P1NP), C-terminal telopeptide of type I collagen (CTX), intact parathyroid hormone (PTH), 25 hydroxy-vitamin D (25 OHD), Sclerostin (SOST), and Dickkopf-related protein 1 (DKK1). Bone mass density was assessed by dual-energy X-ray absorptiometry at the lumbar spine and at the total hip. RESULTS In the groups treated only with TPTD or with denosumab, bone turnover markers increased and decreased, respectively. In TPTD group, a later significant increase in DKK1 was observed, while in denosumab group, a progressive increase in SOST was associated with a progressive significant decrease in DKK1. In the group treated first with denosumab and in which TPTD was added 3 months later, both CTX and P1NP increased 3 months after the beginning of TPTD. The strong effect of denosumab on bone turnover seems to be reversed by TPTD treatment. CONCLUSIONS In this study, we showed that TPTD is able to express its biological activity even when bone turnover is fully suppressed by denosumab treatment. The combination therapy is associated with significant increases in both DKK1 and SOST.

Abstract
Robotic surgery appeared in the Romanian health system in 2008 with the purchase of the first twosurgical robots. One of them belonged to “Dan Setlacec” Center of General Surgery and LiverTransplantation - Fundeni and the second to Floreasca Emergency Clinical Hospital. Funding wasprovided by the Ministry of Health special program. Since the first year of operation by the roboticsystem, the Fundeni Center has performed about 200 interventions. A key objective of the programwas to identify the interventions that are cost efficient, i.e., around 9,000 RON for each surgicalintervention. Subsequently, another 7 robotic systems were put into operation, out of which threeare in urology and four in general surgery. Given the high cost of consumables and post-warrantymaintenance, the operation of these robotic systems could only be done through the national healthsystem, or private sector. The operation of the program allowed for an annual limited number ofcases, and since 2013 the program funding has ceased. During this period, a significant experiencewas gained using robotic surgery in general surgery, urology and gynecology as well.

Abstract
Based on a case operated in our clinic the paper discusses the various applications of robotic surgery in the surgical treatment of the hepatic hydatid cyst. We present the case of a 29- year-old patient who presented to our clinic with chronic abdominal pain (8 months) localized in the right upper quadrant, without irradiation and showing no other accompanying phenomena. The patient was hospitalized and after clinical and laboratory investigations we confirmed the diagnosis of hepatic multilocular hydatid cyst located in the V, VI and VIII segments. Surgery was performed under general anesthesia and with the help of the STANDARD da Vinci robotic system equipped with four arms. The parasite was intactivated, a partial pericystectomy was done and the remaining cavity was drained. The patient's postoperative evolution was favorable and she was discharged in the 8th postoperative day. The 8 month follow-up showed no complications or pathological changes. In conclusion, robotic surgery can be successfully used in the treatment of the hepatic hydatid cyst.

Abstract
We present the case of patient SC aged 44 years who underwent surgery 5 years prior to thepresentation to our clinic for a tumor in the head of the pancreas, the operation than consisted of acephalic duodenopancretectomy which was followed by a number of complications. On admissionthe patient had abdominal pain in the right flank, giant median postoperative eventration and aexternal ”a la Witzel” biliary drainage tube. Abdominal ultrasound revealed the presence of ainterhepaticodiaphragmatic collection that measured 4.6 / 3 cm. A cholangiography was donewhich showed biliary tract opacification of the left lobe with the full stop of the contrast in thedistal left main hepatic duct without intrahepatic biliary dilatation. Surgery was undertaken undertotal anesthesia – the intraoperative diagnosis consisted of: almost complete stenosis of the biliojejunostomy.After the adhesions were cut, the bilio-jejunostomy was redone using the left hepaticduct in a terminal-lateral anastomosis. The collection was drained and the abdominal defect wascorrected. The patient maintained a favorable external biliary drainage of about 200 ml per day soin the 5-th postoperative day the drainage was clamped without any complications. Conclusions: 1. Duodenopancreatectomy should be reserved for average / high volume surgical centers. 2. During the intervention the steps to achieve the biliary-digestive anastomosis should be respectedthoroughly 3. Fast reoperation may increase the chance of survival of the patient.

Abstract
INTRODUCTION Epiphrenic diverticula (ED) represent about 20% of oesophageal diverticula. They are considered to be pulsion diverticula, characterized by out pouchings of the oesophageal mucosa originating in the distal 10 cm of the oesophagus and are frequently associated with spastic oesophageal dysmotility. The most frequent clinical manifestations of ED are dysphagia, regurgitations and chest pain. Only symptomatic diverticula should be treated by surgery. The surgical procedure can be performed minimally invasively by robotic approach and consists of diverticulectomy,hiatus calibration and an antireflux procedure, usually adding an esophagomiotomy as well. CASE-REPORT We present the case of 43-year-old male patient who was admitted for a four-month history of epigastric pain, pyrosis and regurgitations. Preoperative investigation shave shown an epiphrenic diverticulum 6 cm large in diameter.A robotic-assisted transhiatal diverticulectomy with a linear endostapler, hiatal calibration and a Nissen-Rossetti fundoplication were performed using a three-arm da Vinci Robotic System. Operative time was 150 min. Postoperative course was uneventful and the patient was discharged on postoperative day 9, without complications. Ten days later,he came back and was readmitted under emergency status for right chest pain, dyspnoea and fetid breath, being diagnosed with a right empyema secondary to a delayed fistula of the oesophageal suture line. A right minimal pleurotomy and pleural drainage under local anaesthesia were performed and an intravenous antibiotherapy was started with complete remission of symptomatology, the patient remaining asymptomatic after 18 months of follow-up. CONCLUSIONS Robotic approach is a feasible and safe minimally invasive surgical option in the treatment of selected cases of ED. We consider transhiatal abdominal robotic approach possible in almost all cases of ED, regardless of size,thus avoiding thoracic approach and its possible major complications.The most common serious complication after surgery of ED is post diverticulectomy suture line fistula, but if properly and rapidly diagnosed it could be conservatively treated with very good results.

Abstract
BACKGROUND The reported incidence rate of occult thyroid carcinoma in patients operated for benign thyroid pathology has been much higher than expected in the last years,especially for multinodular goitre, which raises the question about which should the proper surgical management for these cases be. AIM To assess the incidence rate of OTC in a single medium volume surgical center and to establish the correct indication for initial surgical management, as well as to identify the benign thyroid pathology most frequently associated with OTC. We also reviewed the relevant scientific literature on this topic. MATERIAL AND METHOD We conducted a retrospective study in the General Surgery Clinic of "Prof. dr. Agrippa Ionescu" Clinical Emergency Hospital, Bucharest, on a series of 145 patients who underwent surgical interventions for preoperatively diagnosed benign thyroid pathology over a ten year period, between 1st January 2002 - 31st December 2012. All cases of known thyroid cancer were excluded. RESULTS Incidence rate of occult thyroid carcinoma in our series was 6.9 % (10 out of 145 patients), 80 % of them being diagnosed with multinodular goitre and two cases (20 %) with Hashimoto's lymphocytic thyroiditis. 6.8 % of all patients with multinodular goitre were found to present occult carcinoma,but this association was without statistical significance(p 0.05). Incidence rate of occult cancer among patients with Hashimoto thyroiditis was proved to be as high as 28.6%,statistically significant (p=0.020). The mean size of postoperatively diagnosed occult microcarcinoma was 7 mm, ranging between 3 mm and 14 mm, 90% of them being smaller than 1cm. Histologically, papillary microcarcinoma was found in all cases. The mean age of the patients diagnosed with occult microcarcinoma was 47.8 years with majority of the female gender. The most frequent operation performed was total thyroidectomy (70.8%). Overall morbidity in our series was 6.9% with a 0.7 % mortality rate (1 case). CONCLUSIONS In our opinion, primary total thyroidectomy should be performed as the procedure of choice for the most part of preoperatively diagnosed benign thyroid pathology and particularly for multinodular goitre and Hashimoto thyroiditis,in order to radically resect all possible foci of aggressive thyroid microcarcinomas.Abbreviations and Acronyms: OTC (Occult Thyroid Carcinoma), PTMC (Papillary Thyroid Microcarcinoma); TT(Total Thyroidectomy), MNG (Multinodular Goitre), GD(Graves' disease), TNG (Toxic Nodular Goitre), FNAB(fine-needle aspiration biopsy).

Abstract
CONTEXT Strontium ranelate reduces vertebral and nonvertebral fracture risk in postmenopausal osteoporosis. OBJECTIVE The objective of this study was to determine the efficacy and safety of strontium ranelate in osteoporosis in men over 2 years (main analysis after 1 year). DESIGN This was an international, unbalanced (2:1), double-blind, randomized placebo-controlled trial (MALEO [MALE Osteoporosis]). SETTING This international study included 54 centers in 14 countries. PARTICIPANTS PARTICIPANTS were 261 white men with primary osteoporosis. INTERVENTION Strontium ranelate at 2 g/d (n = 174) or placebo (n = 87) was administered. MAIN OUTCOME MEASURES Lumbar spine (L2-L4), femoral neck, and total hip bone mineral density (BMD), biochemical bone markers, and safety were measured. RESULTS Baseline characteristics were similar in both groups in the whole population (age, 72.9 ± 6.0 years; lumbar spine BMD T-score, -2.7 ± 1.0; femoral neck BMD T-score, -2.3 ± 0.7). Men who received strontium ranelate over 2 years had greater increases in lumbar spine BMD than those who received placebo (relative change from baseline to end, 9.7% ± 7.5% vs 2.0% ± 5.5%; between-group difference estimate (SE), 7.7% (0.9%); 95% confidence interval, 5.9%-9.5%; P < .001). There were also significant between-group differences in relative changes in femoral neck BMD (P < .001) and total hip BMD (P < .001). At the end of treatment, mean levels of serum cross-linked telopeptides of type I collagen, a marker of bone resorption, were increased in both the strontium ranelate group (10.7% ± 58.0%; P = .022) and the placebo group (34.9% ± 65.8%; P < .001). The corresponding mean changes of bone alkaline phosphatase, a marker of bone formation, were 6.4% ± 28.5% (P = .005) and 1.9% ± 25.4% (P = .505), respectively. After 2 years, the blood strontium level (129 ± 66 μmol/L) was similar to that in trials of postmenopausal osteoporosis. Strontium ranelate was generally well tolerated. CONCLUSIONS The effects of strontium ranelate on BMD in osteoporotic men were similar to those in postmenopausal osteoporotic women, supporting its use in the treatment of osteoporosis in men.

Abstract
BACKGROUND Osteoporosis is a highly prevalent disease and fractures are a major cause of disability and morbidity. AIM The purpose of this study was to characterize post-menopausal women attending osteoporosis centers in Italy, to evaluate physician management, and to determine the incidence of first osteoporotic fracture. SUBJECTS AND METHODS PROTEO-1 was an observational longitudinal study with a 12-month follow-up. Data were collected from women attending osteoporosis centers. Women without prevalent fracture were eligible to enter the 1-yr follow-up phase: the clinical approach to patients according to their fracture risk profile and the incidence of fracture were recorded. RESULTS 4269 patients were enrolled in 80 centers in the cross-sectional phase; 34.2% had an osteoporotic fracture at baseline. Patients with prevalent fractures were older and more likely to be treated compared with non-fractured patients. The incidence of vertebral or hip fracture after 1 yr was 3.84%, regardless of the calculated risk factor profile, and was significantly higher in patients with back pain at baseline (4.2%) compared with those without back pain (2.2%; p=0.023). Generally, physicians prescribed more blood exams and drugs to patients at higher risk of fracture. Among fractured patients only 24% were properly treated; the rate of non-responders to treatment was about 4%. CONCLUSIONS In a large, unselected sample of post-menopausal women attending osteoporosis centers, those without previous fracture were at substantial risk of future fracture, regardless of their theoretical low 10-yr fracture risk. The presence of back pain in women without previous fracture warrants close attention.

Abstract
OBJECTIVE The aim of this observational study, promoted by the Health Authorities of the Regione Veneto (Italy), is to assess the prevalence of the most relevant environmental and individual risk factors in subjects with a recent hip fracture. METHODS Patients aged more than 60 years of both genders with a recent hip fracture not associated with malignancies, were administered questionnaires on dietary habits, sun exposure, and disability score. A complete family, pharmacological and pathology history was collected together with information on previous falls, details of the fracture index, and anthropometric data. In all subjects, blood was taken for the measurement of serum 25 hydroxy-vitamin D (25OHD). RESULTS The study included 704 patients (573 women and 131 men). Mean age was 81 ± 8 years (range 60-102). Severe pre-fracture disability was a common feature (58%) associated with multiple co-morbidities (84%), more frequently cardiovascular and neurological diseases, and specific medications. In a large proportion (86%) of the patients, environmental or individual risk factors for falling were found. Vitamin D insufficiency (serum 25OHD levels < 75 nmol/l) was quite common (70%), particularly in the regional Health Districts were strategies for preventing vitamin D deficiency were not implemented (91%). Only a small proportion (17%) of the study population had been evaluated and treated for osteoporosis. CONCLUSIONS In senile patients with a recent hip fracture, pre-existing disability, multiple co-morbidities, high risk of falling and inadequate intake of calcium and vitamin D is relatively common. Community and case-finding interventions aimed at selecting subjects at high risk of osteoporosis, preventing vitamin D and dietary calcium deficiency, and increasing awareness on the environmental risks of falling are highly warranted.

Abstract
A number of recent findings seem to indicate that fat and bone metabolism are strictly connected. We investigated the relationship between lipid profile and bone mineral density (BMD) in 236 either pre- or postmenopausal women, aged 35-81 years, attending our osteoporosis center ("clinic group"). In order to verify the consistency of the results, 265 men and 481 women aged 68-75, participating in a population-based epidemiological investigation ("community cohort"), were also studied. Lumbar spine, femoral neck, total hip and total body BMD, total body fat, % fat mass and lean mass were measured using dual energy X-ray absorptiometry (DXA). In the clinic group, lumbar spine and hip BMD Z score values were both strongly related to all measured serum lipids: the relationship was negative for HDL cholesterol ( P < 0.05) and Apo A lipoprotein ( P < 0.000) and positive for LDL cholesterol ( P < 0.05), Apo B lipoprotein ( P < 0.001) and triglycerides ( P < 0.05). When BMD values were adjusted for body weight and BMI, most relationships remained statistically significant. In the community cohort, total body and hip BMD values were strongly related in both men and women to age, body weight, height, BMI, fat mass, lean mass, % fat mass. Total body and hip BMD were significantly related to serum lipids in both women and men. The relationship was negative for HDL cholesterol and positive for total cholesterol, triglycerides and LDL cholesterol. Most of these relationships (triglycerides, HDL cholesterol, LDL/HDL cholesterol ratio in women, and all measured lipids in men) remained statistically significant ( P values ranging from 0.000 to 0.03) when the BMD values were adjusted also for anthropometric measures (body weight, height, fat mass). This study demonstrates for the first time that the lipid profile is strictly related to bone mass in both men and women. The interpretation of this association remains hypothetical but it might open new perspectives for understanding the mechanisms controlling bone metabolism.

Abstract
Bisphosphonates have been used with success in the treatment of osteoporosis, but oral therapy often lacks compliance. Here we report the results of clinical trial with aminobisphosphonate neridronate administered intravenously (i.v.). The study included 78 postmenopausal women with spine bone mineral density (BMD) at least -2.5 SD below peak. Patients were randomized to receive for 2 years either 50 mg i.v. neridronate bimonthly and 500 mg calcium plus 400 U vitamin D supplements daily (n=39) or calcium-vitamin D supplements alone (control group, n=39). Treatment was continued over 2 years with an additional 1 year follow-up of calcium-vitamin D supplements alone. Neridronate was well tolerated with the appearance of typical clinical signs of an acute phase reaction in only 3 of the patients after the first infusion. In the control group no significant changes in BMD or bone markers were observed. In the neridronate group BMD rose progressively at the spine rose up to 7.4% +/- 6.1% (SD) and at the femoral neck up to 5.8% +/- 8.2% (SD) at the end of the second year. In the succeeding follow-up these gains were maintained at both skeletal sites. Serum bone alkaline phosphatase (bone ALP) and serum type I collagen C-telopeptide (s-CTX) significantly decreased within 2 months. The bone ALP values reached a -35% plateau after 6 months, while s-CTX attained the lowest mean value (-47%) only by the end of the treatment with neridronate. Both bone markers returned almost to baseline values 1 year after treatment discontinuation. Treatment of postmenopausal osteoporosis with 50 mg i.v. neridronate bimonthly results in clinically relevant increases in BMD, among the largest so far observed with any other bisphosphonate.

Abstract
OBJECTIVE Calcium-sensing receptor (CaR) is a candidate gene for osteoporosis susceptibility. Several CaR polymorphisms have been identified and an association between the A986S genotype and serum calcium levels has been found in Canadian postmenopausal women. We investigated whether the presence of 986S allele was associated with bone mineral density (BMD) and osteoporotic fractures. DESIGN The study group consisted of 164 Italian postmenopausal women without fragility fracture (Fx(-)) and 55 women with fracture (Fx(+)). METHODS A fragment of exon 7 of CaR gene containing three polymorphisms (A986S, R990G and Q1011E) was amplified by PCR and sequenced. Anthropometric characteristics and BMD were evaluated. RESULTS The A986S polymorphism was the most commonly observed (27.9%), whereas the other two CaR polymorphisms, R990G and Q1011E, occurred in a minority of cases (8.8 and 5.5% respectively). There was no significant difference in the frequency distribution of any CaR allele between Fx(-) and Fx(+) patients. Body mass index was found to predict BMD at the lumbar spine and femoral neck. The A986S polymorphism and Years since menopause were not independent predictors of BMD at any site. As far as fracture occurrence, there was no statistically significant difference in the prevalence of fractures between women carrying or not carrying the 986S allele. CONCLUSIONS Our data do not support a role of A986S CaR polymorphism in BMD and in the prevalence of fragility fractures in Italian postmenopausal women.

Abstract
Osteogenesis imperfecta (OI) is a heritable disease of connective tissue, characterized by increased bone fragility. Bisphosphonates currently seems to be the most promising therapy, at least in children. We tested IV neridronate, an amino-bisphosphonate structurally similar to alendronate and pamidronate in adults with OI. Twenty-three men and 23 premenopausal women with OI were randomized to either iv neridronate (100 mg infused intravenously for 30 minutes every 3 months) or no treatment with a ratio of 2 to 1. Control patients were given the same bisphosphonate therapy at the end of the first year. Clinical evaluation included bone densitometry measurements using dual energy X-ray absorptiometry (DXA), fasting serum and urinary biochemistry every 6 months, and radiographs of the spine taken at baseline and after 12 and 24 months of follow-up. Spine and hip bone mineral density rose by 3.0 +/- 4.6% (SD) and by 4.3 +/- 3.9%, respectively, within the first 12 months of treatment, whereas small insignificant changes were observed in the control group. During the second year of follow-up, additional 3.91% and 1.49% increases were observed at the spine and hip, respectively. Markers of skeletal turnover significantly fell during neridronate treatment. Fracture incidence during neridronate treatment was significantly lower than before therapy and compared with controls. Neridronate iv infusions, administered quarterly, significantly increase bone mineral density and lowered the risk of clinical fracture in adults with OI. Bisphosphonate therapy seems to provide clinical benefits, not only to children with OI, but also to adult patients.

Abstract
Osteoporosis is a disease characterized by low bone mineral density (BMD) and up to 80% of its variance is under genetic control. Although osteoporosis is more frequent in women, one-third of hip fractures also occur in men. Much information on genetic factors and bone density has been obtained in women, but only a few studies have been performed in osteoporotic men. We have evaluated the relationship between polymorphisms for several candidate genes such as vitamin D receptor (VDR), collagen type Ia1 (COLIA1), and calcitonin receptor (CTR) in a sample of unrelated Italian men (n = 253, mean age 58.41 +/- 15.64 SD). We found no significant differences in BMD when subjects were stratified for their VDR (BsmI and FokI) and COLIA1 genotypes. BMD both at the lumbar spine and at the femoral neck were associated with polymorphism of CTR gene. The CC genotype of CTR gene had the lowest BMD value (P <0.05 and P <0.01 at the spine and hip, respectively) and its prevalence was significantly over-represented in the subgroup of men with prior hip or vertebral fracture as compared with controls (P = 0.004% c2 = 11.10). The men with the CC genotype also showed significantly lower body mass index (BMI), serum sex hormone binding globulin (SHBG), estradiol, total alkaline phosphatase-(total AP) and bone alkaline phosphatase (bone AP) levels and significantly higher free androgen index (FAI). In conclusion, the polymorphism of CTR gene but not VDR and COLIA1 is associated with osteoporosis incidence and the levels of alkaline phosphatase and estradiol. The lower BMD in CC genotype is apparently associated in males with depressed bone formation and lower estradiol levels.

Abstract
AIMS To describe the effects of two consecutive intravenous infusions of aminohexane bisphosphonate (Neridronate) in patients with active Paget's disease of bone. METHODS The study population included 83 patients, aged 41 to 85 years, randomized to 4 cumulative doses of Neridronate (25, 50, 100, 200 mg) given over 2 days, with a follow up of 180 days. The baseline serum alkaline phosphatase activity was at least 10% above the upper limit of the laboratory range. The response to treatment was assessed by changes in the serum total alkaline phosphatase (primary end point of the study), bone alkaline phosphatase and N-telopeptide urinary excretion. RESULTS All Neridronate doses significantly suppressed the biochemical indices of disease activity. The nadir of total alkaline phosphatase levels ranged from -16 % to -57.5% of pretreatment values in the four groups, with a dose-response relationship that was apparent even between the two highest doses. The proportion of patients still maintaining a partial response (decreases in serum total alkaline phosphatase >25%) at the 6 month follow-up was also related to the dose: 98%, 67%, 57%, 21% in the patients given 200, 100, 50, 25 mg respectively. The proportion of responders in terms of bone alkaline phosphatase and N-telopeptide excretion changes was similar. Bone pain attributed to Paget's disease was significantly reduced. A typical acute phase reaction (fever and/or arthromyalgia) occurred in 16 out of 83 patients. CONCLUSIONS We conclude that all of the Neridronate doses tested here were well tolerated and effective in decreasing, in a dose-related manner the bone turnover parameters of Paget's disease. The highest dose (200 mg) resulted in the normalization of the markers of disease activity in more than 60% of the patients.
