Background: Ghrelin, a known orexigenic hormone, has been demonstrated to be produced and released by salivary glands. Obtaining saliva for metabolism studies would be preferable for patients since the procedure is non-invasive.
Methods: The present study examined serum and salivary ghrelin levels in 41 morbidly obese subjects, 45 healthy controls, and 17 patients with metastatic carcinoma by using a commercial radioimmunoassay.
Results: When comparing serum and salivary levels under fasting conditions, ghrelin levels were significantly higher in saliva for morbidly obese and healthy subjects. A significant correlation between salivary and serum ghrelin could only be demonstrated for healthy subjects. Fasting serum ghrelin concentrations in morbidly obese patients were significantly lower compared with healthy controls and cancer patients, however the levels in whole saliva did not differ significantly between all groups. There was only a highly significant inverse correlation between BMI and serum ghrelin. Serum ghrelin correlated positively with age in morbidly obese. There was no significant difference in serum and saliva ghrelin concentrations between men and women. Following the standardized meal, no significant suppression of serum ghrelin levels in morbidly obese was observed, however salivary ghrelin concentrations were significantly decreased.
Conclusions: The results of the present study support the hypothesis that there is an autonomous production of ghrelin in the salivary glands. Further research should focus on factors involved in the regulation of salivary ghrelin. Until the mechanism of regulation is fully understood, the testing of ghrelin levels in saliva is too limited to recommend a switch from serum testing.

Case: A 35-year-old man with morbid obesity sustained an ultra-low velocity (ULV) rotational knee dislocation secondary to a fall from standing. The patient was successfully treated using a subcutaneous knee-spanning internal fixator, the "INFIX" technique, which has previously been described for pelvic ring injuries.
Conclusion: This novel technique maintained the stable reduction of an ULV knee dislocation in a patient with morbid obesity until adequate healing was achieved.

Background: In cirrhotic patients, portal hypertension increases mortality after surgery. We evaluated the impact of pre-operative transjugular intrahepatic portosystemic shunt (TIPS) on the outcomes of bariatric surgery in cirrhosis.
Methods: Multicentric retrospective cohort.

Background: Lower calyceal anatomy makes the stone clearance a difficult task across all treatment formats. Improvement in optics and miniaturization of instruments have offered an effective and safer alternative to percutaneous nephrolithotomy (PCNL). The study was conducted to compare the efficacy and complications associated with mini-PCNL vs standard-PCNL.

Background: Weight optimization methods in morbidly obese patients with a body mass index (BMI) of ≥40 kg/m2 undergoing total knee arthroplasty (TKA) have shown mixed results. The purpose of this study was to evaluate the effect of perioperative use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in patients with a BMI of ≥40 kg/m2 undergoing primary TKA.
Methods: Using an administrative claims database, patients with morbid obesity undergoing primary TKA were stratified into GLP-1 RA use for 3 months before and after the surgical procedure (treatment group) and GLP-1 RA non-use (control group), and were matched on the basis of patient age, gender, diagnosis of type-2 diabetes mellitus, and Charlson Comorbidity Index (CCI).
