Background: Laparoscopic cholecystectomy (LC) has become the standard treatment for symptomatic cholelithiasis. Bile duct injury and accidental gallbladder perforation with spillage of bile and stone are common complications of LC. This study was carried out to assess the early complications of gallbladder perforation during LC, and identify the risk factor of that perforation. Objectives: to evaluate the early complications which may occur after the perforation of the gallbladder during laparoscopic cholecystectomy and to determine the risk factors which are associated with the perforation of the gall bladder.  Subjects and methods: A prospective comparative study on 192 patients who underwent LC between August 2012 to January 2014 in Baghdad teaching hospital. Data were collected, Patients with and without gallbladder perforation were compared in terms of gender, age, anatomic difficulty, the experience of the surgeon, omental and other organ adhesions to the gall bladder. Results: fifty-five patients had a perforation of GB during LC, 46 patients had GB perforated during dissection of gallbladder bed from hepatic fossa. The mean operative time and duration of postoperative hospitalization were longer in the perforated group, perforation occurs more frequently in acute cholecystitis compared to chronic cholecystitis. There were significant risk factors related to gallbladder perforation which include male gender, AC, adhesion around the gallbladder, and experience of the surgeon. Conclusion: accidental gallbladder perforation leading to longer operative and hospital time which loss the advantage of LC. The male gender, AC, and experience of the surgeon had the main risk factors of the perforated gallbladder.

Aim. To assess the occurrence of SSIs in patients with spillage of gallbladder contents and bacteriobilia during laparoscopic cholecystectomy.Methods. We evaluated 113 patients who underwent laparoscopic cholecystectomy between September 2013 and April 2015. The SSIs and their relationship with gallbladder rupture and bacteriobilia were assessed.Results. The mean age of patients developing SSIs was 45.57 ± 8.89 years. 18 patients (16%) had spillage of bile from the gallbladder. Percentage of SSIs overall was 6%, while percentage of SSIs in gallbladder content spillage was 5.5%. Organism profile of the culture from surgical site showed monomicrobial infection: 58%Staphylococcus aureus, 14%Pseudomonas, and 14%E. coli. The occurrence of SSIs in patients with bacteriobilia was 16% as compared to 2% in patients without bacteriobilia.Conclusions. Gallbladder content spillage is not a significant risk factor leading to increase in SSIs. The occurrence of SSIs is significantly higher in patients with bacteriobilia.

Background: There is little data on the magnitude and factors for functional leg lengthening after primary total knee arthroplasty (TKA). Questions/Purpose: We sought to determine the incidence of and risk factors for functional leg lengthening after primary TKA. Methods: We retrospectively reviewed consecutive unilateral primary TKAs at a single institution from 2015 to 2018. Of the 782 TKAs included, 430 (55%) were performed in women; the mean age was 66 years, and the mean body mass index was 29 kg/m2. Preoperatively, 541 (69%) knees were varus deformities and 223 (29%) were valgus deformities. Hip to ankle biplanar radiographs were obtained preoperatively and 6 weeks postoperatively for all patients. Two independent researchers measured leg length, coronal plane deformity, lateral knee flexion angle, and overall mechanical alignment on all preoperative and postoperative radiographs. Results: The mean overall ipsilateral functional leg lengthening was 7.0 mm. Seven hundred knees (90%) were overall functionally lengthened, including 462 (59%) knees lengthened >5 mm and 250 (31%) knees lengthened 10 mm or more. A valgus deformity and coronal plane deformity of 10° or more were significant risk factors for increased functional lengthening. Patients with severe valgus deformities (>10°) had the largest amount of functional lengthening, at a mean of 13.5 mm. Conclusion: After primary TKA, 90% of limbs are functionally lengthened, including roughly one-third over a centimeter. Valgus knee deformities and severe deformities (>10°) were significant risk factors for increased limb lengthening.

Background Steroid-resistant nephrotic syndrome (SRNS) often develops into end stage renal disease. Previous studies have reported that NPHS2 gene mutation, gender, and atopic history are risk factors associated with SRNS. Interethnic, sociocultural, and environmental differences have also been suggested to affect these mutations.Objective To analyze possible risk factors for SRNS, including NPHS2 gene mutations (412C→T and 419delG), gender and atopic history, in Indonesian subjects with SRNS.Methods A case-control study with 153 subjects, consisting of 88 SRNS patients and 65 control subjects, was undertaken in 10 Indonesian teaching centre hospitals from September 2006 to December 2007. Analysis of the NPHS2 gene mutation in 412 C→T was performed by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR), while that for the NPHS2 gene mutation in 419delG was performed by restriction fragment length polymorphism (RFLP). Data was analyzed by multiple logistic regression.Results In our Indonesian subjects, the significant risk factors for SRNS were male gender (OR=2.21; CI 95%:1.07-4.56, P=0.036), NPHS2 412C→T gene mutation (OR=18.07; CI 95%:6.76-48.31, P<0.001), and NPHS2 419delG gene mutation (OR=4.55; CI 95%:1.66-12.47, P=0.003). However, atopic history was not a significant risk factor for SRNS (OR=1.807; CI 95%:0.642-5.086, P=0.262).Conclusion NPHS2 412C→T and 419delG gene mutations, as well as male gender are risk factors for SRNS in Indonesian subjects. Atopic history was not significantly associated with SRNS in our subjects. [Paediatr Indones. 2011;51:272-6].

Purpose.To determine the differences in risk factors for retinopathy of prematurity (ROP) in paired twins.Methods.A retrospective medical record review was performed for all paired twins screened for ROP between 2007 and 2012. Screening was offered to very low birth weight (≤1500 grams) and preterm (≤32 weeks) neonates. Twins 1 and 2 were categorized based on the order of delivery. Maternal and neonatal covariates were analyzed using univariate and multivariate regression analyses for both ROP and Type 1 ROP.Results.In 34 pairs of Chinese twins, the mean gestational age (GA) was 30.2 ± 2.0 weeks. In Twin 1, smaller GA (OR = 0.44,P=0.02), higher mean oxygen concentration (OR = 1.34,P=0.03), presence of thrombocytopenia (OR = 1429.60,P<0.0001), and intraventricular hemorrhage (OR = 18.67,P=0.03) were significant risk factors for ROP. For Twin 2, a smaller GA (OR = 0.45,P=0.03) was the only risk factor. There were no significant risk factors for ROP in Twin 1 or Twin 2 on multivariate analysis.Conclusion.In Chinese twin pairs, smaller GA was the only common risk factor for ROP while Twin 1 was more susceptible to the postnatal risks for ROP.

Background and purpose: Hematoma growth unrelated to aneurysmal rebleeding has been poorly studied, but is not a rare complication following endovascular embolization of ruptured cerebral aneurysms. The aim of this study is to elucidate the possible risk factors for this phenomenon. Methods: We included 101 consecutive patients with subarachnoid hemorrhage (SAH) who underwent endosaccular embolization at our institution within 72 hours of symptom onset in this study. All endovascular procedures were conducted under intraprocedural systemic anticoagulation. Age, gender, hypertension, diabetes, preoperative antiplatelet or anticoagulation use, neurological grade, Fisher computed tomography group, location and size of the aneurysm, the grade of aneurysm occlusion, and timing of endovascular procedure were retrospectively analyzed to find the risk factors for hematoma growth. Results: This series included 32 men (31.7%) and 69 women (68.3%), and the mean age ± SD was 65.5 ± 14.0 years. The mean time ± SD from onset to endovascular procedure was 12.1 ± 14.0 hours. Following the procedure, hematoma growth unrelated to aneurysmal rebleeding occurred in 14 patients (13.9%), and 10 of the 14 patients required surgical removal of hematoma and/or ventriculostomy to control intracranial pressure. All 14 patients had an anterior circulation aneurysm and had Fisher group 3 or 4 SAH. Ultra-early embolization (conducted within 6 hours after onset), female gender, history of hypertension, and poor neurological grade (WFNS grades 4 and 5) were significant risk factors of hematoma growth (p < 0.05 for all) by the univariate logistic analysis. In multivariate analysis, ultra-early embolization (OR, 18.0; 95% CI, 3.26-338; p = 0.0002), and female gender (OR, 9.83; 95% CI, 1.73-187; p = 0.0067) were independent risk factors for this phenomenon. Anterior circulation aneurysm and Fisher group 3 or 4 SAH did not suit for the logistic regression model, but were found to be significant risk factors by chi-square test (p = 0.018 and 0.022, respectively). Conclusions: Ultra-early endovascular embolization for ruptured cerebral aneurysm under systemic anticoagulation increases the risk of growth of hematomas unrelated to aneurysmal rebleeding. In addition, women with anterior circulation aneurysm presenting with dense focal SAH or intracerebral hematoma are at higher risk for this phenomenon.

Abstract Background Gram-negative-resistant bacterial infections are increasing due to widespread use of antibiotics. Infections caused by Klebsiella spp. are an important part of healthcare-associated infections and cause morbidity and mortality. The aim of this study was to determine the epidemiological, clinical features, carbapenem resistance rates and risk factors of bloodstream infections of children with Klebsiella spp. Methods In this retropective study, medical records of 85 episodes of 75 patients caused by with Klebsiella spp. bacteriaemia who admitted to Ege University Faculty of Medicine, Pediatric Hospital in Turkey between 2014 and 2017 were evaluated. Conventional biochemical methods were performed using the automated systems of MALDİ-TOFF MS / VITEK 2 (Biomerieux, France). According to EUCAST recommendations, VITEK 2 (Biomerieux, France) automated microdilution method was used in sensitivity tests. Results The mean age of 85 episodes included in the study was 3.49 (±5.4) years. 58% of the patients were male and 42% were female. 18.8% of the patients were premature. The most common service was newborn service (30.6%). Neutropenia was 26% and thrombocytopenia was 55% at the time of diagnosis. Klebsiella pneumonia was 93% and Klebsiella oxytoca was 7%. Carbapenem resistance rate was found to be 30.6% in Klebsiella spp. Carbapenem resistance was found 18% in 2014, 38% in 2015, 42% in 2016 and 25% in 2017. In patients who developed carbapenem-resistant Klebsiella infection, the duration of pre-hospitalization ≥14 days (P = 0.034), the absolute neutrophil count < 100 (P = 0.048) and steroid use (P = 0.025) were statistically significant risk factors. The mean length of hospital stay was 107 (±103) days. Klebsiella spp. attributable mortality due to infection was 14% and crude mortality was 15%. No statistically significant difference was found in patients who developed resistant and susceptible infections. Conclusion Carbapenem resistance in Klebsiella infections was increased. Prolonged hospital stay, neutropenia and steroid use in the last 3 months were identified as significant risk factors for carbapenem-resistant Klebsiella infections.

Introductions: Laparoscopic cholecystectomy (LC) occasionally demands conversion to open cholecystectomy (OC) because of multiple risk factors. This study was conducted to find out whether male gender is a stand-alone risk factors for conversion of LC to OC. Methods: This was a comparative analysis of conversion of LC to OC in patients operated for symptomatic cholelithiasis during June 2017 to May 2018 at Bir hospital, National Academy of Medical Sciences, Kathmandu, Nepal. The patients were divided into two groups: male (group 1) and female (group 2). Study variables included gender, America Society of Anesthesiologist class, history of upper abdominal pain within six weeks prior to surgery, upper abdominal surgery, emergency department visit due to upper abdominal pain, adhesion of gallbladder to adjacent structure and body mass index. Binominal logistic regression analysis of risk factors for conversion was conducted. Odds ratio (95% CI) was calculated. The p value ≤ 0.05 was considered statistically significant. Results: Among 151 patients (male 39, female 112), 7 (4.6%, male 3 and female 4) had conversion from LC to OC. Male gender itself as an isolated risk factor had no significant association to conversion (p=0.303). There was no significant difference found for age, operating time and hospital stay. Previous emergency visit (p=0.020) and adhesion (p<0.030) were associated with conversion. Conclusions: Male gender had no significant association for conversion of LC to open. Previous emergency visit due to upper abdominal pain and adhesion of gallbladder were associated risk factors for conversion.

Purpose. To evaluate the prevalence, possible risk factors, and clinical results of femtosecond laser implanted intrastromal corneal ring segment (ICRS) extrusion in keratoconic eyes. Patients and Methods. This is a retrospective observational study evaluating 333 eyes of 269 patients who were subjected to femtosecond laser-implanted Keraring ICRS in the Sohag Refractive Center, Sohag, Egypt, from January 2014 to January 2019. The study included eyes with channels created by a femtosecond laser (60 kHz IntraLase femtosecond system; Advanced Medical Optics, Santa Ana, California, USA) with implantation of Keraring intrastromal corneal ring segments (Mediphacos, Belo Horizonte, Brazil). Patient data and causes of Keraring extrusions were identified as being those rings that migrated or showed melting of the cornea with no other reason which required segment removal. Results. Seven eyes were found to fit the criteria of ring extrusion (2.1%) out of the 333 eyes which had Keraring implantation. All extruded rings were from patients with keratoconus grade 3, with eccentric cones, and with femtosecond creation of the tunnel. Four eyes belonging to 3 patients (57.1%) had a history of vernal Keratoconjunctivitis, yet they did not show signs of activity at the time of implantation. They reported excessive rubbing just before they presented with conjunctival hyperemia and foreign body sensation. Five eyes (71.4%) showed chronic sun exposure. The mean minimal corneal thickness was 401.85 μm (range 384–420 μm), while the mean maximum keratometry was 61 D (range 55.18–68.96 D). Most of the extruded rings had large arcs. Six eyes had crosslinking (CXL) at the same session of the Keraring implantation. The simultaneous CXL treatment is considered as a possible significant risk factor for ring extrusion. Conclusion. ICRS is an effective reversible option for patients with keratoconus who are intolerant to hard contact lenses, yet the choice of cases and ring segments is mandatory for satisfactory results. Moreover, meticulous history taking and examination reduces the incidence of complications including extrusion.

Abstract Abnormal TCD defined as high mean maximum velocities &gt; 200 cm/sec are highly predictive of stroke risk and justify long term transfusion program. Outcome and risk factors of conditional TCD defined as velocities 170–200 cm/sec remains to be described. Patients and methods Since 1992, 371 pediatric SCD patients (303 SS, 44 SC, 18 Sß+, 6 Sß0) were systematically explored once a year by TCD. The newborn screened cohort (n=174) had the first TCD exploration between 12 and 18 months of age. TCD was performed with a real-time imaging unit, using a 2 MHz sector transducer with color Doppler capabilities. Biological data were assessed at baseline, after the age of 1.5 years and remotely of transfusion or VOC. We report the characteristics and the outcome in patients (n=43) with an history of conditional TCD defined by mean maximum velocities ranging between 170 and 200 cm/s in the ACM, the ACA or the ICA. Results: The mean follow-up of TCD monitoring was 5,5 years (0 – 11,8 y). All patients with an history of conditional doppler were SS/Sb0 (n=43). Mean (SD) age of patients at the time of their first conditional TCD was 4.3 years (2.2) whereas in our series the mean age at abnormal TCD (&gt; 200 cm/sec) occurrence was 6.6 years (3.2). Comparison of basal parameters showed highly significant differences between patients with conditional TCD and those with normal TCD: Hb 7g4 vs 8g5 (p&lt;0.001), MCV 82.8 vs 79 (p=0.047). We also had found such differences between patients with normal and those with abnormal TCD (Hb and MCV p&lt; 0.001). Two patients were lost of follow-up. Two patients died during a trip to Africa. Conditional TCD became abnormal in 11/43 patients and justified transfusion program. Mean (SD) conversion delay was 1.8 (2.0) years (range 0.5–7y). No stroke occurred. 16 patients required a treatment intensification for other indications (frequent VOC/ACS, splenic sequestrations): 6 were transplanted and 10 received HU or TP. Significant risk factors (Pearson) of conversion to abnormal were the age at time of conditional TCD occurrence &lt; 3 y (p&lt;0.001), baseline Hb &lt; 7g/dl (p=0.02) and MCV &gt; 80 (p=0.04). MRI/MRA was performed in 31/43 patients and showed ischemic lesions in 5 of them at the mean (SD) age of 7.1 y (1.8) (range 4.5–8.9): no significant difference was observed in the occurrence of lesions between the 2 groups. Conclusions This study confirms the importance of age as predictive factor of conditional to abnormal TCD conversion with a risk of 64% when first conditional TCD occured before the age of 3 years. TCD has to be frequently controled during the 5 first years of life.

Abstract Aims Bile duct injury (BDI) is a major complication of cholecystectomy resulting in long-term consequences. The relatively low incidence (0.23% – 1.5%) of BDI makes the identification of risk factors challenging. The aim of this study was to systematically analyse available literature on BDI post-cholecystectomy to provide an update on the incidence and determine current risk factors. Methods The study was pre-registered on PROSPERO (CRD42020177318). A search was conducted of MEDLINE, EMBASE, Scopus, Cochrane Central, Web of Science databases and the grey literature from inception to February 2020. 1583 unique papers were identified and screened for eligibility. English language, retrospective and prospective studies were included where the population age was &gt; 16 and underwent cholecystectomy. Results Outcomes analysed were incidence of BDI and risk estimates for possible risk factors. 30 studies (6,420,667 patients) were included in the meta-analysis. Gender, BMI&gt;30, acute cholecystitis (AC), emergent surgery, the operative approach, intraoperative cholangiography (IOC) and the impact of surgeon’s experience were analysed. Male gender and AC were determined to be statistically significant risk factors (OR 1.25 (1.13-1.39)) and 1.74 (1.27-2.39) respectively). Furthermore, IOC use was found to be significantly associated with BDI risk (OR 1.27 (1.17 – 1.37), while BMI&gt;30, open surgical approach, emergent surgery and surgeon’s experience were not statistically significant; however, significant heterogeneity among included studies limited the interpretation of these factors. Conclusion Male gender and AC were found to be predictors of BDI, while better quality evidence is needed to show the effect of other factors.
