Background: Screening for obstructive sleep apnea (OSA) is recommended as part of the preoperative assessment of obese patients scheduled for bariatric surgery. The objective of this study was to compare the sensitivity of oximetry alone versus portable polygraphy in the preoperative screening for OSA. Methods: Polygraphy (type III portable monitor) and oximetry data recorded as part of the preoperative assessment before bariatric surgery from 68 consecutive patients were reviewed. We compared the sensitivity of 3% or 4% desaturation index (oximetry alone) with the apnea-hypopnea index (AHI; polygraphy) to diagnose OSA and classify the patients as normal (<10 events per hour), mild to moderate (10-30 events per hour), or severe (>30 events per hour). Results: Using AHI, the prevalence of OSA (AHI>10 per hour) was 57.4%: 16.2% of the patients were classified as severe, 41.2% as mild to moderate, and 42.6% as normal. Using 3% desaturation index, 22.1% were classified as severe, 47.1% as mild to moderate, and 30.9% as normal. With 4% desaturation index, 17.6% were classified as severe, 32.4% as mild, and 50% as normal. Overall, 3% desaturation index compared to AHI yielded a 95% negative predictive value to rule out OSA (AHI>10 per hour) and a 100% sensitivity (0.73 positive predictive value) to detect severe OSA (AHI>30 per hour). Conclusions: Using oximetry with 3% desaturation index as a screening tool for OSA could allow us to rule out significant OSA in almost a third of the patients and to detect patients with severe OSA. This cheap and widely available technique could accelerate preoperative work-up of these patients. © 2009 Springer Science + Business Media, LLC.

Aim: The clinical guidelines reported by the French-Speaking Diabetes Society (Société francophone du diabète) include updated recommendations for preconceptual planning and care in the management of pregnancy in women with type 1 diabetes mellitus (T1DM). Methods: The working group included diabetologists, as well as an obstetrician, a nurse and a dietician. A review of the literature was performed using PubMed and Cochrane databases. Guidelines published by foreign diabetes societies were also consulted. Results: In women with T1DM, pregnancy increased the risks of hypoglycaemia, diabetic ketoacidosis, pregnancy-induced hypertension, infections and worsening of diabetic microvascular disease. Moreover, T1DM during pregnancy had an impact on the embryo and the fetus, and may have increased the risk of spontaneous miscarriages, malformations, premature births, and fetal and neonatal complications. However, intensive glycaemic control and preconceptual care have been shown to decrease the rate of fetal demise and malformations. Also, the use of insulin analogues during pregnancy is now regarded as safe. Tight glucose control and frequent follow-up are recommended throughout pregnancy in women with T1DM. Their obstetric management should take place in a maternity hospital with an appropriate perinatal environment and in close collaboration with diabetologists. Conclusion: Pregnancy planning and adequate management during pregnancy are mandatory for improving the outcomes of women with T1DM. © 2012 Elsevier Masson SAS.

Background Pituitary tumors account for approximately 15% of primary intracranial neoplasms and often are diagnosed incidentally. Common sellar lesions are pituitary adenomas, craniopharyngiomas, and Rathke cleft cysts. Currently endoscopic transsphenoidal approaches are largely used, and many centers also use 3-dimensional (3D) technology, although additional results of long-term follow-up are still being accumulated. Methods We present a retrospective analysis of 104 patients with sellar lesions (57 male and 47 female, mean age 52 years) who underwent 3D endoscopic transsphenoidal surgery in our center from December 2011 to March 2015 and were followed up for a mean time of 18 months. Results A total of 16 patients were diagnosed with growth hormone-secreting adenomas, 9 with adrenocorticotropic hormone-secreting, 5 with prolactin-secreting, and 2 with thyroid-stimulating hormone-secreting tumors and 58 with nonsecreting pituitary adenomas. Five patients had Rathke cleft cysts, 5 craniopharyngiomas, 2 fibrous solitary tumors, 1 a metastasis, and 1 a chordoma. At baseline, 47 patients (45.2%) had hormonal changes and 52 (50%) had visual field changes. Complete resection was achieved in 73 patients (70.1%). Follow-up evaluation detected hormonal remission in 7 patients with Cushing disease (77.7%) and in 11 patients with acromegaly (68.7%). Complications were cerebrospinal fluid leak in 5 cases (4.8%) and transient diabetes insipidus in 6 cases (5.7%). A total of 55 patients (52.9%) were discharged less than 72 hours after surgery. Conclusions The use of an endoscopic endonasal approach with 3D technology provides several advantages relating to patient length of stay, rate of complications, postoperative recovery, and novice surgeons' training. Advantages of 3D endoscopy and long-term follow-up still need further elucidation. © 2016 Elsevier Inc. All rights reserved.

Background: Gastric banding still represents one of the most widely used bariatric procedures. It provides acceptable weight loss in many patients, but has frequent long-term complications. Because different types of bands may lead to different results, we designed a randomized study to compare the Lapband® with the SAGB®. We hereby report on the long-term results. Methods: Between December 1998 and June 2002, 180 morbidly obese patients were randomized between Lapband® or SAGB®. Weight loss, long-term morbidity, and need for reoperation were evaluated. Results: Long-term weight loss did not differ between the two bands. Patients who maintained their band had an acceptable long-term weight loss of between 50 and 60 % EBMIL. In both groups, about half the patients developed long-term complications, with about 50 % requiring major redo surgery. There was no difference in the overall rates of long-term complications or failures between the two groups, but patients who had a Lapband® were significantly more prone to develop band slippage/pouch dilatation (13.3 versus 0 %, p < 0,001). Conclusions: Although in the absence of complication, gastric banding leads to acceptable weight loss; the long-term complication and major reoperation rates are very high independently from the type of band used or on the operative technique. Gastric banding leads to relatively poor overall long-term results and therefore should not be considered the procedure of choice for the treatment of morbid obesity. Patients should be informed of the limited overall weight loss and the very high complication rates. © 2013 Springer Science+Business Media New York.

Aims: Primary hyperparathyroidism (pHPT) is characterized by an increased frequency of glucose tolerance abnormalities associated with insulin resistance. Few studies evaluated the prevalence of metabolic syndrome (MetS) in pHPT and whether there are differences between asymptomatic pHPT patients and symptomatic ones. Thus, we sought to investigate the prevalence of MetS in pHPT patients in comparison to the prevalence of MetS in Italian population. Subjects and methods: We conducted a retrospective chart review of 294 pHPT patients, of these 154 [age (mean±SD) 58.7±13.3 yr, body mass index 25.6±4.8 kg/m2; serum calcium (11.3±1.2 mg/dl) 2.8±0.3 mmol/l; PTH 234.8±224.3 ng/l] met the inclusion criteria. A modified National Cholesterol Educational Program (NCEP)/Adult Treatment Panel III (ATP III) definition of the MetS was used. Prevalence of MetS was compared with that reported for the Italian population (Progetto Cuore Study). Results: The prevalence of the MetS (34/154, 22.1%) was similar to that reported in the general Italian population. Asymptomatic pHPT patients were older (62.1±12.7 vs 56.4±13.2 yr, p<0.008) and showed higher prevalence of MetS than symptomatic ones (30.2% vs 16.5%, p<0.045). Moreover the prevalence of nephrolitiasis or overt bone disease was not different between patients MetS+pHPT compared to MetS-pHPT, whereas femoral bone mineral density (BMD) was higher in MetS+pHPT (p<0.003). In the logistic regression model age and femoral BMD were independent predictors of MetS. Conclusions: The prevalence of MetS in pHPT is not increased in comparison to the general population, thus, its diagnosis is not an appropriate tool to identify the additional cardiovascular risk related to pHPT. Difference in age affects the increased prevalence of MetS in asymptomatic pHPT patients. ©2012, Editrice Kurtis.
