Abstract Background Primary hyperparathyroidism (PHPT), the most common cause of hypercalcemia, is most often identified in postmenopausal women. The clinical presentation of PHPT has evolved over the past 40 years to include three distinct clinical phenotypes, each of which has been studied in detail and has led to evolving concepts about target organ involvement, natural history, and management. Methods In the present review, I provide an evidence-based summary of this disorder as it has been studied worldwide, citing key concepts and data that have helped to shape our concepts about this disease. Results PHPT is now recognized to include three clinical phenotypes: overt target organ involvement, mild asymptomatic hypercalcemia, and high PTH levels with persistently normal albumin-corrected and ionized serum calcium values. The factors that determine which of these clinical presentations is more likely to predominate in a given country include the extent to which biochemical screening is used, vitamin D deficiency is present, and whether parathyroid hormone levels are routinely measured in the evaluation of low bone density or frank osteoporosis. Guidelines for parathyroidectomy apply to all three clinical forms of the disease. If surgical guidelines are not met, parathyroidectomy can also be an appropriate option if no medical contraindications are present. If either the serum calcium or bone mineral density is of concern and surgery is not an option, pharmacological approaches are available and effective. Conclusions Advances in our knowledge of PHPT have guided new concepts in diagnosis and management.

Objectives Canine ventral atlantoaxial stabilization methods have been constantly evolving over the past few decades. Yet, proper experimental data comparing the feasibility and biomechanical properties of currently available surgical options are lacking. The aims of this study were (1) to describe and compare the safety profiles and biomechanical properties of three ventral atlantoaxial stabilization methods; and (2) to test whether recently reported optimal implant definitions constitute reasonable guidelines. Methods Three types of atlantoaxial stabilization including trans-articular screw fixation (TSF) and two cemented constructs (MI5 and MI6) were performed in 21 Beagle cadavers. Post-surgical computed tomography (CT) images of the constructs and biomechanical data were then generated and statistically analysed. Results The CT data revealed that TSF achieved significantly better apposition than cemented constructs. Out of 91 screws positioned, 4.4% were graded as dangerous and 86.8% as optimal. Optimal positioning was most challenging to obtain for mono-cortical screws. Analysis of biomechanical data suggested that all three techniques could likely achieve similar rates of atlantoaxial fusion when submitted to physiological loads but also that cemented constructs were less prone to failure compared with TSF. Clinical Significance This study provides evidence that all three techniques are technically feasible and biomechanically viable but also that the evaluated surgical guidelines could be improved.

Current Surgical Guidelines covers the main conditions requiring surgical care, such as breast cancer, critically ill surgical patients, and diverticular disease, and focuses on the evidence and selection criteria which determine the best action to take. Recommendations are graded according to relevant current guidelines and all benefits/risk decision recommendations are supported by easy-to-digest facts and figures.

Peritoneal dialysis has become an effective and widely used technique for the treatment of patients with end-stage renal disease. Peritoneal dialysis has become more practical for use in pediatric patients since equipment and techniques have been adapted for smaller patients. In the present work we describe the surgical technique that we currently use at our institution for surgical placement of peritoneal dialysis catheter. From January 1985 to January 1992, 19 peritoneal catheters were placed in 17 children, at the Bambino Gesù Children's Hospital. At the time of catheter insertion the average weight of the children was 14.2 kg., and the average age was 4 y. 10m. Peritoneal dialysis catheters were always placed under sterile conditions, in an operating room or in a pediatric ICU, with surgical technique. Regarding our surgical technique we recommend: 1) to use Tenckhoff catheter, 2 cuffs pigtail (curled) type; 2) to perform a minilaparatomy with lateral surgical approach and a routine omentectomy; 3) to create a submuscular tunnel (rectus abdominis) to reduce the leakaqe of peritoneal dialysis fluid. Furthermore the various clinical problems encountered in our experience and some surgical guidelines for the prevention of complications are reviewed.

A distal third of lower extremity defect is challenging for plastic surgeons. The standard for treatment is microsurgery. Recently, perforator flap has been reported for small to medium defects. The objective was to analyze the outcomes of perforator flaps for distal third of lower extremity defects and to establish surgical guidelines. A retrospective review of patients with defects in distal third of lower extremities was conducted. Patients with multiple levels of lower extremity defects were excluded. A total of 8 patients with distal third of lower extremity defects were included. Seven patients were male. Overall mean age was 35.3 (18-60) years. Patients had 3 anterior, 3 lateral, and 2 medial defects. Lateral and anterior defects in 6 patients were closed using a peroneal-based propeller perforator flap with an angle of rotation of 90° to 160°. Medial defects in 2 patients were closed using a posterior tibial-based perforator advancement flap. Three patients (37.5%) developed venous congestion. No complications occurred for patients with medial defect closure using an advancement posterior tibial-based perforator flap. No total flap loss was observed. The perforator flap provides a similar texture to the skin at recipient area and a wide range of rotation. Perforator flaps should be the first choice for defects reconstruction in distal third lower extremities. Perforator flaps can be used for small to large defects, and can be moved by propeller or advancement depending on the perforator location. A guideline for perforator flaps reconstruction of the distal third of lower extremity defects was established.
