Review
INTRODUCTION
Tamsulosin is the most commonly used medical expulsive therapy (MET). However, it does not alleviate ureteral colic. It is important to develop MET that can reduce ureteral colic while maintaining a high stone clearance rate. Silodosin is an α1A adrenoceptor with high affinity and selectivity for the distal ureter, which may reduce ureteral colic and enable stone expulsion for distal ureteral stones. Therefore, we performed this systematic review and meta-analysis to evaluate the efficacy of silodosin as MET and its role in reducing ureteral colic among patients with distal ureteral stones.
MATERIALS AND METHODS
This research was conducted in accordance with the Cochrane Handbook for Systematic Review and Intervention, in adherence with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, and was registered in the International Prospective Register of Systematic Reviews (PROSPERO CRD42021249003). A comprehensive literature search was performed in several databases including Medline, EMBASE, and Scopus up to July 2021 for randomized trials comparing silodosin with placebo for MET. RevMan 5.4 was used for data analysis.
RESULTS
A total of six randomized controlled trials were included in this analysis with a total of 907 patients. Our analysis revealed that the patients who received silodosin had significantly higher stone expulsion rate (SER) (odds ratio [OR] 3.33, 95% confidence interval [CI] 2.34, 4.76, P < 0.01), significantly shorter stone expulsion time (SET) (mean difference -3.79, 95% CI -4.51, -3.06, P < 0.01), and lower analgesic use (OR 0.4, 95% CI 0.23, 0.69, P < 0.01) compared to the group receiving placebo.
CONCLUSION
Silodosin showed significantly higher SER, lower SET and lower analgesic use in patients with distal ureteral stones as compared to a placebo.

Review
BACKGROUND
Recipient vessels proximal to the zone of injury have traditionally been preferred for lower extremity reconstruction. However, more recent data have shown mixed outcomes when performing anastomoses distal to the zone of injury. We investigated the impact of recipient vessel location on free flap outcomes.
METHODS
Retrospective review (1979-2016); 312 soft tissue free flaps for open tibia fractures met inclusion criteria. Flap characteristics and perioperative outcomes were examined. Systematic review identified articles evaluating anastomosis location and flap outcomes; pooled data analysis was performed.
RESULTS
More anastomoses were performed proximal to the zone of injury (80.7%) than distal (19.3%). Distal anastomoses were not associated with increased take back rates (19.6%) compared with proximal (23.8%) anastomoses ( = 0.356). Regression analysis comparing proximal and distal anastomoses found no difference in partial flap failures (7.4% vs 11.9%; = 0.978) or total flap failures (9.3% vs 9.3%; = 0.815) when controlling for the presence of arterial injury, flap type, and time from injury to coverage. Systematic review yielded 11 articles with 1,245 proximal and 127 distal anastomoses for comparison. Pooled analysis ( = 0.58) and weighted comparative analysis ( = 0.39) found no difference in flap failure rates between proximal and distal groups.
CONCLUSION
Our results are congruent with the current lower extremity literature and demonstrate no difference in perioperative complication rates between anastomoses performed proximal or distal to the zone of injury. These findings suggest that anastomotic location choice should be based primarily on recipient vessel quality/flow and ease of access/exposure rather than orientation relative to the zone of injury.

Review
OBJECTIVE
Although much has been investigated about the effects of cervical headgear, there remains some controversy. Therefore, the objective of this systematic review is to disclose the actual effects of the cervical headgear appliance, based on articles of relevant quality.
METHODS
A literature review was conducted using PubMed, Web of Science, Embase, Scopus and Cochrane databases. Inclusion criteria consisted of human studies written in English; published between 1970 and 2014; in which only the cervical headgear was used to correct Class II malocclusion; prospective or retrospective; with a clear description of cervical headgear effects; with a sample size of at least 15 individuals. No comparative studies, clinical cases or cases with dental extractions were included and the sample should be homogeneous.
RESULTS
Initially, 267 articles were found. A total of 42 articles were selected by title and had their abstracts read. Finally, 12 articles were classified as with high quality and were used in this systematic review.
CONCLUSIONS
The cervical headgear appliance proved efficient to correct Class II, Division 1 malocclusion. Its effects consisted in correction of the maxillomandibular relationship by restriction of maxillary anterior displacement; distalization and extrusion of maxillary molars; and slight maxillary expansion.

Review
STATEMENT OF PROBLEM
The gingival zenith (GZ) influences the line angle position in the emergence profile and the axial inclination of the crown. Irregularities in GZ symmetry and contour have a negative impact on dental esthetics. GZ location is not consistently distal to the crown's long axis; instead, it tends to be more distal in anterior teeth. The GZ levelling of the lateral incisor is often described as either level with or slightly above the zenith line connecting the central incisor and canine teeth, but there are also reports of GZ being aligned apically to the zenith line. Controversial reports persist regarding GZ positioning, magnitude, and location, potentially leading to inadequate positioning and levelling of the GZ in esthetic restorative therapy.
PURPOSE
The purpose of this systematic review and meta-analysis was to assess the scientific evidence related to GZ level, position, and symmetry in maxillary incisors and canines.
MATERIAL AND METHODS
This study adhered to the population, variable, outcome (PVO) criteria and the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist. Cross-sectional studies involving healthy adults with complete dentition of the maxillary anterior sextant were subjected to prevalence analysis and quantitative measurement to assess the gingival zenith level and position. Data were extracted, and methodological quality was appraised using the Joanna Briggs Institute critical appraisal checklist for analytical cross-sectional studies. Certainty of evidence was evaluated through the grading of recommendations, assessment, development, and evaluation (GRADE) system.
RESULTS
The GZs were distally positioned, coinciding with the tooth axis or mesially positioned in, respectively, 96%, 3%, and 1% on central incisors; 84%, 14%, and 1% on lateral incisors; and 43%, 44%, and 5% on canines. GZ distal positioning was greater in central incisors, followed by lateral incisors and canines. In lateral incisors, the GZ was levelled coronally in 82% of the population. Contralateral symmetry was observed for GZ levelling and positioning. The certainty of the evidence was very low for all comparisons.
CONCLUSIONS
The frequency and magnitude of the distal position of the GZ increased the more anterior the tooth. Axially, the GZ was frequently levelled coronally to the zenith line. The contralateral positioning and levelling of the GZ was symmetrical.

Review
BACKGROUND
Restoring lumbar lordosis is important for adult spinal deformity surgery. Several reports have suggested that lumbar lordosis distribution has a significant impact on the outcome of surgery, including lumbar distribution index (LDI), proximal lumbar lordosis (PLL), and distal lumbar lordosis (DLL). The features of lumbar lordosis distribution are inconclusive in asymptomatic adults.
QUESTIONS/PURPOSES
We sought to evaluate the variation of lumbar lordosis distribution (LDI, PLL, and DLL) and to identify associated factors in asymptomatic adult volunteers.
METHODS
We performed a systematic review of the Embase and Medline databases to identify studies in asymptomatic adult volunteers to evaluate lumbar lordosis distribution including LDI, PLL, and DLL.
RESULTS
Twelve articles met eligibility criteria and were included in our review. The respective pooled estimates of mean and variance, respectively, were 65.10% (95% confidence interval [CI]: 62.61-67.58) and 13.70% in LDI, 16.51° (95% CI: 5.54-27.49) and 11.46° in PLL, and 35.47° (95% CI: 32.79-38.18) and 9.10° in DLL. Lumbar lordosis distribution was associated with race, age, sex, body mass index, pelvic incidence, and Roussouly classification.
CONCLUSIONS
This systematic review found that despite a wide variation in LDI and PLL, DLL is maintained in a narrower range in asymptomatic adult volunteers, especially in white populations. Distal lumbar lordosis may be a more reliable radiographic parameter to restore the lumbar lordosis distribution in preoperative planning.

Medicine Dec 2023Accomplish a thorough review on the existing biomechanical and clinical studies about coronal plane fractures of the distal femur.
BACKGROUND
Accomplish a thorough review on the existing biomechanical and clinical studies about coronal plane fractures of the distal femur.
METHODS
We performed an electronic search of PubMed/MEDLINE database from April to June, 2023. The terms for the database search included "Hoffa fractures," OR "Busch-Hoffa fractures" OR "coronal plane fractures of the distal femur."
RESULTS
The search identified 277 potentially eligible studies. After application of inclusion and exclusion criteria, 113 articles were analyzed in terms of the most important topics related to coronal plane fractures of the distal femur.
CONCLUSION
Lateral coronal plane fractures of the distal femur are more frequent than medial, present a more vertical fracture line, and usually concentrate on the weight bearing zone of the condyle. The Letenneur system is the most used classification method for this fracture pattern. Posterior-to-anterior fixation using isolated lag screws (for osteochondral fragments-Letenneur type 2) or associated with a posterior buttressing plate (when the fracture pattern is amenable for plate fixation-Letenneur types 1 and 3) is biomechanically more efficient than anterior-to-posterior fixation. Anterior-to-posterior fixation using lag screws complemented or not by a plate remains a widely used treatment option due to the surgeons' familiarity with the anterior approaches and lower risk of iatrogenic neurovascular injuries. There is no consensus in the literature regarding diameter and number of screws for fixation of coronal plane fractures of the distal femur.

Meta-Analysis Review
The clinical implication of minimally invasive versus open pancreatoduodenectomy for non-pancreatic periampullary cancer: a systematic review and individual patient data meta-analysis.
BACKGROUND
Most studies on minimally invasive pancreatoduodenectomy (MIPD) combine patients with pancreatic and periampullary cancers even though there is substantial heterogeneity between these tumors. Therefore, this study aimed to evaluate the role of MIPD compared to open pancreatoduodenectomy (OPD) in patients with non-pancreatic periampullary cancer (NPPC).
METHODS
A systematic review of Pubmed, Embase, and Cochrane databases was performed by two independent reviewers to identify studies comparing MIPD and OPD for NPPC (ampullary, distal cholangio, and duodenal adenocarcinoma) (01/2015-12/2021). Individual patient data were required from all identified studies. Primary outcomes were (90-day) mortality, and major morbidity (Clavien-Dindo 3a-5). Secondary outcomes were postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), blood-loss, length of hospital stay (LOS), and overall survival (OS).
RESULTS
Overall, 16 studies with 1949 patients were included, combining 928 patients with ampullary, 526 with distal cholangio, and 461 with duodenal cancer. In total, 902 (46.3%) patients underwent MIPD, and 1047 (53.7%) patients underwent OPD. The rates of 90-day mortality, major morbidity, POPF, DGE, PPH, blood-loss, and length of hospital stay did not differ between MIPD and OPD. Operation time was 67 min longer in the MIPD group (P = 0.009). A decrease in DFS for ampullary (HR 2.27, P = 0.019) and distal cholangio (HR 1.84, P = 0.025) cancer, as well as a decrease in OS for distal cholangio (HR 1.71, P = 0.045) and duodenal cancer (HR 4.59, P < 0.001) was found in the MIPD group.
CONCLUSIONS
This individual patient data meta-analysis of MIPD versus OPD in patients with NPPC suggests that MIPD is not inferior in terms of short-term morbidity and mortality. Several major limitations in long-term data highlight a research gap that should be studied in prospective maintained international registries or randomized studies for ampullary, distal cholangio, and duodenum cancer separately.

Comparative Study Meta-Analysis Review
BACKGROUND
Studies have been published comparing spleen-preserving distal pancreatectomy (SPDP) with distal pancreatectomy with splenectomy (DPS), but the results remain inconsistent. The aim of this study was to compare SPDP with DPS by conducting a systematic review and meta-analysis.
METHODS
Literature searches of the Medline/PubMed, Embase, and Cochrane Library databases were performed to identify relevant studies published before April 30,2015. Perioperative outcomes of SPDP and DPS were evaluated. The meta-analysis was performed in random- or fixed-effects models, as appropriate. A subanalysis was conducted to compare the two techniques of splenic preservation: splenic vessel preservation (SVP) and Warshaw technique (WT).
RESULTS
Eighteen studies and 1156 patients were included in the comparison between SPDP and DPS. A total of 502 of these patients underwent SPDP and 654 underwent DPS. Meta-analysis showed the SPDP group had significantly fewer infectious complications (odds ratio [OR] 0.57, P = 0.006), less operative blood loss (P<0.0001), lower overall morbidity rate (OR 0.66, P = 0.002), and lower clinical pancreatic fistula rate (OR 0.42, P = 0.002) than the DPS group. Subanalysis indicated the SVP group had significantly lower rate of spleen infarction (OR 0.12, P<0.00001) and fewer secondary splenectomies (OR 0.13, P = 0.008) than the WT group.
CONCLUSIONS
SPDP was a safe procedure associated with better short-term outcomes than DPS. SVP could provide more sufficient blood perfusion for the conserved spleen than WT. However, the evidence is limited, and more randomized controlled trials are warranted.

Review
BACKGROUND
The required distal margin in partial mesorectal excision (PME) is controversial. The aim of this systematic review was to determine incidence and distance of distal mesorectal spread (DMS).
METHODS
A systematic search was performed using PubMed, Embase and Google Scholar databases. Articles eligible for inclusion were studies reporting on the presence of distal mesorectal spread in patients with rectal cancer who underwent radical resection.
RESULTS
Out of 2493 articles, 22 studies with a total of 1921 patients were included, of whom 340 underwent long-course neoadjuvant chemoradiotherapy (CRT). DMS was reported in 207 of 1921 (10.8%) specimens (1.2% in CRT group and 12.8% in non-CRT group), with specified distance of DMS relative to the tumor in 84 (40.6%) of the cases. Mean and median DMS were 20.2 and 20.0 mm, respectively. Distal margins of 40 mm and 30 mm would result in 10% and 32% residual tumor, respectively, which translates into 1% and 4% overall residual cancer risk given 11% incidence of DMS. The maximum reported DMS was 50 mm in 1 of 84 cases. In subgroup analysis, for T3, the mean DMS was 18.8 mm (range 8-40 mm) and 27.2 mm (range 10-40 mm) for T4 rectal cancer.
CONCLUSIONS
DMS occurred in 11% of cases, with a maximum of 50 mm in less than 1% of the DMS cases. For PME, substantial overtreatment is present if a distal margin of 5 cm is routinely utilized. Prospective studies evaluating more limited margins based on high-quality preoperative magnetic resonance imaging and pathological assessment are required.

OBJECTIVE
To evaluate the consistencies and inconsistencies between distal cholangiocarcinoma (DCCA) and pancreatic ductal adenocarcinoma (PDCA) regarding their biological features and long-term prognosis.
METHODS
PubMed, the Cochrane Library, and EMBASE were searched to find comparative studies between DCCA and PDCA. RevMan5.3 and Stata 13.0 software were used for the statistical analyses.
RESULTS
Eleven studies with 4,698 patients with DCCA and 100,629 patients with PDCA were identified. Pooled results indicated that patients with DCCA had a significantly higher rate of preoperative jaundice (p = 0.0003). Lymphatic metastasis (p < 0.00001), vascular invasion (p < 0.0001), and peri-neural invasion (p = 0.005) were more frequently detected in patients with PDCA. After curative pancreaticoduodenectomy (PD), a significantly higher R0 rate (p < 0.0001) and significantly smaller tumor size (p < 0.00001) were detected in patients with DCCA. Patients with DCCA had a more favorable overall survival (OS) (p < 0.00001) and disease-free survival (DFS) (p = 0.005) than patients with PDCA. However, postoperative morbidities (p = 0.02), especially postoperative pancreatic fistula (POPF) (p < 0.00001), more frequently occurred in DCCA.
CONCLUSION
Patients with DCCA had more favorable tumor pathological features and long-term prognosis than patients with PDCA. An early diagnosis more frequently occurred in patients with DCCA. However, postoperative complications, especially POPF, were more frequently observed in patients with DCCA.
