RESUMO
PURPOSE: To assess the safety and efficacy of super-mini PCNL (SMP, 14 Fr) when compared to standard PCNL (sPCNL, 24-30 Fr) in the management of renal calculi of size ranging from 1.5 to 3 cm. METHODS: From February 2021 to January 2022, a total of 100 patients were randomized to either SMP group or sPCNL group in a 1:1 ratio (50 in each group) using computer-generated simple randomization. Demographic data, stone characteristics, operative times, perioperative complications, blood transfusions, postoperative drop in haemoglobin, postoperative pain, duration of hospital stay and stone-free rates were compared between the two groups. RESULTS: Mean stone volume (2.41 cm2 vs 2.61 cm2) and stone-free rates (98% vs 94%, p = 0.14) were similar in both the SMP and sPCNL groups, respectively. The SMP group had significantly longer mean operative times (51.62 ± 10.17 min vs 35.6 ± 6.8 min, p = 0.03). Intraoperative calyceal injury (1/50 vs 7/50, p = 0.42) and mean postoperative drop in haemoglobin (0.8 ± 0.7 g/dl vs 1.2 ± 0.81, p = 0.21) were lower in the SMP group, but not statistically significant. SMP group showed significantly lower mean postoperative pain VAS scores (5.4 ± 0.7 vs 5.9 ± 0.9, p = 0.03) and mean duration of hospital stay (28.38 ± 3.6 h vs 39.84 ± 3.7 h, p = 0.0001). Complications up to Clavien grade 2 were comparable, with grade ≥ 3 complications higher in the standard group, but not statistically significant. CONCLUSION: Super-mini PCNL is equally effective as standard PCNL in treating renal calculi up to 3 cm, with significantly reduced postoperative pain and duration of hospital stay and lower risk of Clavien grade ≥ 3 complications, although with higher operative times.

Background: Due to the anatomical intricacy of the region and the possibility of psychological as well as physical damage, maxillofacial injuries are unusual. Studies have shown that general psychological morbidity is more prevalent following maxillofacial trauma leading to post-traumatic stress disorder and behavioural changes at various times. Purpose: To evaluate the quality of life and levels of stress, depression and anxiety in patients following facial trauma. Methodology: Prospective research including 30 patients with maxillofacial injuries was conducted. Based on the requirements for inclusion and exclusion, these patients were included in the trial and were provided with psychological counselling and guidance from their time of admission till the follow-up period. The baseline levels of quality of life, depression, anxiety and stress symptoms were assessed at the time of presentation (T0), 1 month (T1) and 3 months (T2), using the Depression Anxiety Stress Scale-21 and World Health Organization Quality of Life-BREF questionnaire. Results: The levels of stress, anxiety and depression, as well as quality of life, did not differ significantly (p > 0.05). Conclusion: There is no correlation between maxillofacial trauma and levels of anxiety, depression, stress and quality of life if the subjects are exposed to psychotherapy and guidance.
RESUMO
Multiple myeloma (MM) is a plasma cell malignancy, and its typical radiographic presentation includes punched-out radiolucency of the skull. It is a bourgeois description of myeloma and often holds good in most cases. However, the diagnosis can get tricky when a patient walks into the clinic with non-specific signs and symptoms. Many suspicions arise when we examine a well-defined mandibular swelling, but the real picture is revealed with thorough screening. This article presents a rare mandibular swelling diagnosed as MM, emphasizing important differential diagnoses for maxillofacial surgeons and pathologists.
RESUMO
Ureters are essential components of the urinary system and play a crucial role in the transportation of urine from the kidneys to the bladder. In the current study, a three-dimensional ureter is modelled. A series of peristaltic waves are made to travel on the ureter wall to analyse and measure parameter effects such as pressure, velocity, gradient pressure, and wall shear at different time steps. The flow dynamics in the ureters are thoroughly analysed using the commercially available ANSYS-CFX software. The maximum pressure is found in the triple wave at the ureteropelvic junction and maximum velocity is observed in the single and double wave motion due to the contraction produced by the peristalsis motion. The pressure gradient is maximum at the inlet of the ureter during the single bolus motion. The contraction produces a high jet of velocity due to neck formation and also helps in urine trapping in the form of a bolus, which leads to the formation of reverse flow. Due to the reduction in area, shear stress builds on the ureter wall. The high shear stress may rupture the junctions in the ureter.
