4%). In the tail region of pancreas, the most common variation was Type IIb (n = 21, 4%) followed by Type IIa (n = 19, 3.6%).<br /><br /> Pancreatic contour variations are not very uncommon in daily practice. Knowledge of these variations is important for surgeons, radiologists and avoids misjudgement of normal pancreatic tissue as tumor or lymph node especially on unenhanced or single phase MDCT.<br /><br />Pancreatic contour variations are not very uncommon in daily practice.

The aim of this study was to determine the added value of MIBI scan and its effect on the operative plan via a hypothetical model where a stepwise approach is conducted and MIBI is considered only after the ultrasound is evaluated.<br /><br /> Patients who underwent parathyroidectomy for primary hyperparathyroidism (PHPT) between 2012 and 2019 at two tertiary centers were included. Data collected included demographic data, preoperative workup, operative findings and follow-up. The added value of MIBI scans was determined for patients with positive ultrasound.<br /><br /> A total of 513 patients with positive US result and a MIBI scan were included. If a stepwise approach was conducted then MIBI scan would not change the operative plan in 492 (95.9%). Among the remaining 21 patients, MIBI scan would correctly change the ultrasound-based operative plan in only 12 (2.3%) patients, while incorrectly change the plan in 9 (1.8%), resulting in unnecessary exploration of the contralateral side. In patients with sonographic appearance of a parathyroid gland larger than 1.2cm, MIBI scan would correctly change the operative plan in only 1 of the 287 (0.35%) patients.<br /><br /> Our study suggests that the routine use of MIBI scans may have limited added value in patients with PHPT and a positive neck ultrasound, especially in those with adenoma size larger than 1.2cm. Positive ultrasound alone may be sufficient for the preoperative localization of parathyroid disease.<br /><br />Our study suggests that the routine use of MIBI scans may have limited added value in patients with PHPT and a positive neck ultrasound, especially in those with adenoma size larger than 1.2 cm.

Study period was 2010 to 2017. The inclusion criteria were operatively treated cholecystitis or another benign disease of the gallbladder. Further, the time of day the operation was performed must have been documented. We defined nighttime as all interventions performed between 7PM until 6AM. A total of 11'459 patients were included. Development of any complication during hospitalization and in-hospital mortality was the main outcomes. The first part of the study was solely descriptive. In the second part, we applied a 11 case-control-matching. A matched group of 274 pairs were further investigated.<br /><br /> Only 8.4% of the procedures were performed during nighttime. Complications occurred in 6.7% of all patients. We found twice as many complications in the nighttime group compared to the daytime group. Mortality was 0.56% during daytime and 0.52% during nighttime. In a matched-pair analysis, however, we found no significant differences in the overall mortality rate nor in the occurrence of complications when comparing day-vs. nighttime operations.<br /><br /> We found twice as many complications in the nighttime group (12%) compared to the daytime group (6.1%), mainly related to patient risk factors. In contrast to common apprehension, however, nighttime cholecystectomies were not associated with higher mortality rates.<br /><br />We found twice as many complications in the nighttime group (12%) compared to the daytime group (6.1%), mainly related to patient risk factors.

However, the efficacy of Yoga has not been studied in chest trauma patients.<br /><br /> This randomized controlled trial was conducted at level-1 Trauma Centre. Isolated chest injury patients were randomized into either standard physiotherapy or Yogatherapy groups. Patients in physiotherapy group received conventional chest physiotherapy and Yogatherapy group received a set of Yogic exercises in addition to conventional chest physiotherapy. Primary outcome measure was changes in pulmonary function tests (PFT) at 4weeks of discharge. Secondary outcomes were changes in quality of life (QoL), respiratory muscle strength and endurance, chest wall mobility, and levels of cytokines at 4weeks. Data were analyzed using STATA v14.0.<br /><br /> A total of 89 eligible patients were randomized to physiotherapy (n = 46) and Yoga therapy (n = 43) groups. Demographic characteristics were comparable in both the groups. There were statistically significant improvements in PFT in the Yogatherapy group compared with physiotherapy with an increase in Forced vital capacity (p = 0.02) and Forced expiratory volume (p = 0.01) at 4weeks. In addition, there were significant improvement in physical component of QoL, respiratory muscle endurance (p = 0.003) and axillary cirtometry (p = 0.009) in the Yogatherapy group. However, no statistically significant difference in the trends of cytokine markers seen between the groups.<br /><br /> Yoga was found to be effective in improving pulmonary functions and QoL in patients with chest trauma.
