Objective A surgical site infection after oculoplastic surgery is a serious complication that can lead to endophthalmitis and vision loss. Although performing these procedures in a minor-surgery setting is common, there is a lack of evidence in the literature regarding the incidence of postoperative infections. The objective of this study was to determine the infection rate associated with elective outpatient oculoplastic procedures performed in a minor-surgery setting. Methods A retrospective review was completed for all patients who underwent elective oculoplastic surgery in the minor-procedure room at the Misericordia Health Centre in Winnipeg between April and December 2018. Operations were performed by 2 senior oculoplastic surgeons. Data collected included the type of procedure, number of surgical incisions, type and number of sutures, use of prophylactic antibiotics, time to follow-up, complications, and presence of surgical site infection. Results Review of 539 patients showed an infection rate of 0.37% (2 of 539). Infection cases were an exposed orbital implant using a temporalis fascia graft and ptosis repair using a frontalis sling. Thirteen complications were identified, corresponding to a complication rate of 2.41% (13 of 539). Conclusion Study results show an infection rate of 0.37% for elective oculoplastic surgery in a minor-procedure setting.

Background Nutritional management of children with epidermolysis bullosa (EB) presents multiple challenges including reduced oral intake compounded by mucosal fragility. Gastrostomy tube feeding is effective in improving nutritional status however there is limited data on the safety and tolerance of this technique in EB children. We aim to review the effectiveness and morbidity of our minimally invasive two-port laparoscopic-assisted gastrostomy (LAG) approach using Seldinger techniques with serial dilatations in children with EB. Methods A retrospective, observational cohort study was conducted on all consecutive EB patients who underwent LAG tube insertion between 2009-2019. Patient demographics, admission details and 12-month clinical outcomes were reported. Results 32 EB patients underwent LAG placement. Median age at insertion was 7.3 (IQR ± 6.3) years, with 8 (25.0%) and 3 (9.4%) of patients also undergoing oesophageal dilatation and fundoplication, respectively. Minor complications arose in 58.1% of patients including: peri-stomal overgranulation (25.8%), gastrostomy infection (22.6%), pain (22.6%), mild gastrostomy leakage (16.1%), blockage (9.7%) and device failure (3.2%). 2 patients (6.5%) developed major complications with extensive gastrostomy site leakage. Improvements in growth were reflected in mean height Z-scores (-1.99 to -1.71). Mean weight Z-scores improved in patients aged 0-10 years (-2.30 to -1.61) and mean BMI Z-scores increased in patients over 10 years (-2.71 to -1.46). No cases of gastrostomy-related mortality were reported. Conclusion LAG is well-tolerated in EB patients with improvements in growth and minimal morbidity 12-months post-gastrostomy insertion. An extended follow-up period is required to ascertain the long-term implications of gastrostomy feeding.

Intravascular lithotripsy (IVL) is a novel tool for the treatment of calcified vascular stenosis. Recently, IVL has been successfully used for modification of calcified plaque in coronary and lower extremity peripheral arteries with promising results. However, experience in subclavian and innominate peripheral arterial disease is limited. This study aims to report our initial experience of IVL use in calcified subclavian and innominate vasculature.This was a retrospective review of all the cases of IVL performed in subclavian and innominate arteries at the Miriam Hospital, Providence, between January 2019 and May 2020. Data on the baseline and procedural characteristics were collected. The primary endpoint was procedural success defined as residual stenosis of20% after stenting. Other endpoints of interest were; 1) procedural complications, including dissections, perforations, abrupt closure, slow or no-reflow, thrombosis, and distal embolization; 2) in-hospital major adverse cardiac events (MACE) defined as a composite of death, myocardial infarction, or stroke/transient ischemic attack.A total of 7 patients with 13 lesions undergoing IVL were included. Of these, 5 (71%) were women, the mean age was 74.6 ± 12.9, and the mean BMI was 25.1 ± 6.7. IVL was successfully delivered to all the target lesions with a mean 252.9 ± 54.4 pulses delivered per patient. Procedural success was achieved in 100% of the treated lesions. No procedure-related complications or in-hospital MACE occurred in any of the patients.In this single-center retrospective analysis, IVL facilitated acute procedural success without any procedural complications in severely calcified stenoses of the subclavian and innominate vasculature. Larger studies with an active comparator and longer follow-up are needed to establish the relative efficacy and safety of IVL use in this vascular bed.

Background: Definitive closure of fistula-in-ano poses an ongoing surgical challenge. The OVESCO OTSC® Proctology Clip (proctology clip) purports to offer improved preservation of the anal sphincter whilst at the same time curing the fistula by closure. Methods: A retrospective record review was conducted for patients who received the proctology clip as part of the management of fistula-in-ano in the Colorectal Unit at Wits Donald Gordon Medical Centre (WDGMC). Results: There were 19 cases of fistula-in-ano treated with the proctology clip. All were cryptoglandular in origin. The median age was 50 years (IQR 44–56 years) and post-procedure, the median follow-up duration was 145 days (IQR 63–298 days). Overall, 9 procedures were successful (47%). Success rates were higher for simple (66.7%) as opposed to complex (38.5%) fistula-in-ano. For patients who underwent placement of the proctology clip as a primary procedure, the success rate (50%) was slightly better than those who received the clip as a secondary procedure (44.4%). Conclusion: This preliminary data presents our initial experience using the proctology clip. While these data may serve as a “proof of concept”, a multi- centre controlled trial comparing this method to the rectal mucosal advancement flap (RMAF) is needed to determine the role of the proctology clip in the management of fistula-in-ano.

BACKGROUND Patent Foramen Ovale (PFO) has a high estimated prevalence (25% of the general population) and has been implicated in the pathogenesis of cryptogenic stroke and transient ischemic attack (TIA), as well as in the pathogenesis of migraine headache. This study evaluated the effectiveness of percutaneous transcatheter PFO closure with Amplatzer devices, from a large single-center experience. METHODS from January 1998 to December 2014, 577 patients (243 males and 334 females, mean age 50 years, range 11-82 years) with documented PFO and history of at least one episode of cryptogenic stroke/TIA (n=356) or occasional finding of previous ischemic lesions on MRI (n=221) underwent percutaneous transcatheter closure of PFO using an Amplatzer™ Occluder. All the procedures were performed under general anesthesia or mild sedation, and were assisted by transesophageal or intracardiac echocardiography. RESULTS Procedural success was 100%. After a median follow-up period of 2.7 years with echocardiographic evaluations, the rate of recurrent adverse cerebral events was 0.4%. Two patients (0.4%) required a secondary procedure for significant residual shunt. Of 36 patients with minor residual shunt, 30 (83%) showed spontaneous shunt regression at follow-up. There was a consistent decrease after procedure in headache migraine, Platypnea-Orthodeoxia, fainting episodes, syncope, and Coenaesthesia Phenomena. CONCLUSIONS Transcatheter PFO closure is an effective and safe therapy for the prevention of thromboembolic events in the patients with cryptogenic stroke/TIA or an occasional finding of a positive cerebral MRI. Late follow-up shows device stability and clinical improvement in the majority of patients.

BACKGROUND: There is lack of data on long-term outcomes of patients with Budd-Chairi Syndrome (BCS) treated with medical therapy including anticoagulation alone. METHODS: Consecutive patients (N = 138, mean [standard deviation, SD] age 29.3 [12.9] years; 66 men) with BCS, treated with medical therapy alone including anticoagulation, with minimum follow-up of 12 months were included. Initial response was classified as complete (CR), partial (PR) or nonresponse (NR) and on follow-up as loss of response (LoR) or maintenance of response (MoR). The association of baseline, clinical and biochemical parameters with different responses was evaluated. RESULTS: Seventy-six patients (55.1%) had CR, 26 (18.8%) had PR and 36 (26.1%) had NR. None with PR or NR had CR later. At a median follow-up of 40 (range 12–174) months, LoR was more common in PR group than in CR group (12 [46.2%] vs 18 [23.7%], P = 0.03). LoR was associated with presence of ascites (odds ratio [OR] 1.5; 95% confidence interval [CI] 0.06–0.71), gastrointestinal bleed (OR 1.33; 95% CI 0.09–0.82) or jaundice (OR 1.01; 95% CI 0.11–0.97) at baseline and duration of follow-up (OR 0.018; 95% CI 1.006–1.030). Mortality was higher in NR (28 [77.8%]) compared with CR (15 [19.7%], P = 0.001) and PR (8 [30.8%], P = 0.001). On binary logistic regression analysis, presence of ascites at baseline was associated with LoR (OR 0.303 [0.098–0.931]). CONCLUSION: Patients with initial CR have better survival than nonresponders. One-third had LoR on follow-up. The presence of ascites at baseline is associated with LoR.

Background The suspected scaphoid fracture remains a diagnostic conundrum with over-treatment a common risk-averse strategy. Cross-sectional imaging remains the gold standard with MRI recommended but CT used by some because of easier access or limited MRI availability. The aim of this feasibility study was to evaluate whether cone beam computed tomography (CBCT) could support early diagnosis, or exclusion, of scaphoid fractures. Methods Patients with a suspected scaphoid were recruited fracture between March and July 2020. All underwent a 4-view X-ray. If this examination was normal, they were immediately referred for a CBCT scan of the wrist. Those with a normal scan were discharged to research follow-up at 2 and 6-weeks. Results 68 participants were recruited, 55 had a normal or equivocal X-ray and underwent CBCT. Nine additional radiocarpal fractures (16.2%) were demonstrated on CBCT, the remainder were discharged to research follow-up. Based on the 2-week and 6-week follow up three patients (4.4%) were referred for MRI to investigate persistent symptoms with no bony injuries identified. Conclusions CBCT scans enabled a rapid pathway for the diagnosis or exclusion of scaphoid fractures, identifying other fractures and facilitating early treatment. The rapid pathway also enabled those with no bony injury to start rehabilitation, suggesting that patients can be safely discharged with safety-net advice following a CBCT scan.

Surgeons treating advanced carcinoma of the tongue with total glossectomy face many conflicts in view of the morbidity and poor functional and survival outcomes following surgery. It is pertinent to study the patients undergoing total tongue compartment resection as a separate cohort to analyse their outcomes. This study investigated the oncological outcomes of 150 patients with advanced tongue squamous cell carcinoma who underwent total glossectomy. The results suggest that compartment resection significantly improved local control, irrespective of margin status. The presence of multiple positive nodes was found to be an independent poor prognostic factor, and adjuvant radiation significantly improved survival. Total glossectomy is feasible and safe in both the primary and salvage setting and should be considered as the surgical option for advanced tongue cancer.

Background Prepectoral implant-based reconstruction using synthetic meshes is feasible with good outcomes. We present our data using TiLOOP® Bra Pocket, a novel ready-to-use mesh pocket which acts as an internal bra and prevents the implant from dislocating or twisting. Materials and Methods A single-centre retrospective cohort study was performed to assess short-term complication rates and cosmetic outcomes in patients with prepectoral implant-based reconstruction using the TiLOOP® Bra Pocket. The primary endpoint was complication rates during the first 6 months. The secondary endpoint was the cosmetic outcome after 6 to 12 months, which was judged by two breast surgeons using the Harvard score. Results A total of 63 breasts (43 patients) were reconstructed using the TiLOOP® Bra Pocket between 2018 and 2020, 57 were immediate reconstructions. The overall complication rate was 30,2% (n = 19/63). Major complications occurred in seven breasts (n = 7/63; 11,1%) and minor complications occurred in 12 breasts (12/63; 19,0%). The unplanned revision rate was 12,7%. The cosmetic outcome was good (Harvard score: mean 3, range 1–4; SD 0,75). Seventeen cosmetic complications were observed (17/63; 27,0%) and six cosmetic revision surgeries were performed (6/63; 9,5%). Conclusion The use of the TiLOOP® Bra Pocket is convenient and standardized because the pocket is preformed and does not require to be sewn first. Cosmetic outcome is good; however, the surgical morbidity needs to be addressed in future reconstructions. Careful patient selection and preparation techniques are vital in order to achieve acceptable complication rates and satisfying cosmetic results.

Background/Aim. The availability of thrombopoietin receptor agonists (TPO-RA) for treating primary immune thrombocytopenia (ITP) has transformed its management over the last decade. The aim of this study was to assess the efficacy of TPO-RA in adults with chronic ITP treated at the University Clinical Center of Serbia. Methods. A total of 28 adult ITP patients ( 10 m ales and 18 females), who were given eltrombopag and/or romiplostim, were enrolled in the study. Data on demographic characteristics, ITP duration, previous therapeutic modalities, comorbidities, concomitant therapy both for comorbidities and ITP, indications for TPO-RA, bleeding episodes before and during TPO-RA, TPO-RA doses, adverse events, and response rates were collected from the patients? medical records. TPO-RAs were administered in patients with chronic refractory ITP when splenectomy was contraindicated/unfeasible and as preparation for splenectomy. Favorable treatment response was defined as a stable platelet count ? 50 ? 109/L. Results. A total of 22 (78.57%) and 14 (50.0%) patients were treated with eltrombopag and romiplostim, respectively. A good treatment response (GTR) was achieved in 81.8% of the patients receiving eltrombopag and 71.4% of those treated with romiplostim. The non-responders to eltrombopag (4 patients) and those who had lost their response to eltrombopag (4 patients) were switched to romiplostim. Six of 8 patients achieved a GTR. At the time of TPO-RA initiation, 46.4% of the patients used concomitant ITP therapy, which was ceased in all those with a GTR. The following adverse effects of TPO-RA were registered: transaminitis and transient ischemic attack for eltrombopag ? one patient each, and pulmonary embolism in one romiplostim-treated patient. Conclusion. Our study showed that TPO-RAs are an effective and safe treatment option since the majority of patients achieved stable remission without bleeding episodes.

Objective Uterine artery embolization is an attractive option for the management of postpartum haemorrhage, however it is not available in every hospital. We compared the clinical characteristics and haemodynamic state of patients with postpartum haemorrhage, before and after helicopter transfer to a tertiary hospital for possible uterine artery embolization. We also analysed whether the type of treatment could modify the outcome. Study design: Between 1999 and 2019 in Switzerland, we retrospectively found 82 consecutive patients with postpartum haemorrhage who were transferred by a physician-staffed helicopter emergency medical service to the tertiary hospital for potential uterine artery embolization. The collected data included the type of delivery, estimated blood loss, shock index and blood lactate levels before transfer and at destination, uterine artery embolization rate and hospital mortality rate. Our primary outcome was to describe the clinical characteristics, outcomes and haemodynamic state of the patients with postpartum haemorrhage before and after helicopter transfer. Our secondary outcome was to report the treatments performed at the tertiary hospital. The collected data were analysed with Stata version 14 (Stata Corporation, College Station, TX, USA). Continuous data are compared by using the Student's t-test or the Mann-Whitney U test, as appropriate. Results We included 69 patients. Postpartum haemorrhage occurred after vaginal delivery in 38 cases (55%). Blood loss prior to transfer exceeded 2 L in 34% of cases. The median shock index was 1 (IQR 0.8 to 1.1) before transfer and 0.9 (IQR 0.8 to 1.1) after transfer (p=0.41). The median lactate level was 2.9 mmol/L (IQR 2.1 to 6.8) before, and 2.1 mmol/L (IQR 1.55 to 3.5) after transfer (p=0.90). Forty-four patients underwent uterine artery embolization (64%), with an overall success rate of 93%. One patient died (1.4%), from a haemorrhagic shock of abdominal origin. Conclusions Interhospital helicopter transfer of patients with postpartum haemorrhage to a tertiary hospital seems to be safe in our setting, despite a significant proportion of patients exhibiting signs of haemodynamic instability. Decision criteria would be helpful to better guide choices regarding the transfer of patients with postpartum haemorrhage.

Introduction. A percutaneous transhepatic approach has been used to place tunneled catheters in the inferior vena cava for hemodialysis. This route through the suprahepatic vein could be used to place a tunnelled catheter for permanent haemodialysis without complications and with an excellent permeability rate. Single centre expirience. From 2011 to 2020 in a Military Medical Academy we treated 4 patients with transhepatic central venous catheter for hemodialysis. All of them had exhausted approaches during period of hemodialysis. Arterio-venous fistulas had been thrombosed on the arms, thrombosis subclavian vein billateraly or superior cava veinand complications by femoral catheters was present. Peritoneal dialysis was not possible. Discusion. Limited number of papers descripted outcome of placement transhepatic catheters for hemodialysis. In our expirience one patient needed scroll catheter due hemodialysis had not well outcome, and one patient needed thrombolysis catheter.Two of them are on hemodialysis without complications for 300 and 1650 days. Conclusion. The transhepatic venous access under ultrasound and radioscopic guidance is a simple and safe method. It is an acceptable alternative for permanent haemodialysis catheters when other venous accesses are exhausted, and when it is performed by a well-trained team.

Background/Aim. Pregnancy-induced red blood cell (RBC) alloimmunization is important not only because of the possible negative effects on subsequent pregnancy outcomes in case the fetus carries the antigen but also because of the optimal trans-fusion management in cases of obstetric hemorrhage. Timely detection of RBC antibodies is part of testing, prevention, and treatment strategy, aimed at achieving better outcomes for alloimmunized mothers with an affected fetus. The aim of the study was to determine the frequency and specificity of alloantibodies among pregnant women from the South Backa District, Serbia, with special attention to the incidence of anti-D alloantibodies. Methods. A retrospective study was conducted in the Blood Transfusion Institute of Vojvodina and covered the period from January 1, 2010, to December 31, 2019. Screening and antibody identification were performed by an indirect antiglobulin test in gel-microcards (ID-Card Liss/Coombs) with two test RBC (ID-DiaCell I-II screening cells, Bio-Rad, Cressier, Switzerland) on an automated system (IH-500, Bio-Rad). Results. Among 25,694 tested pregnant women, 1.38% were actively immunized, while 1.12% of women acquired antibodies in the current pregnancy. Among 3,622 (14.09%) RhD-negative women, 1.77% produced anti-D antibodies during the ongoing pregnancy. Distribution of anti-body specificity was: anti-D 23.34%, anti-M 11.85%, anti-E 9.41%, anti-K 9.41%, anti-C 5.92%, anti-Fyb 5.92%, anti-c 3.13%, anti-S 3.13%, anti-Lea 3.13%, anti-Leb 3.13%, anti-Cw 1.75%, anti-Jka 1.40%, anti-P 1.05%, anti-Lub 0.70%, anti-Fya 0.35%, autoantibody of undetermined specificity 0.70%, and irregular antibodies of undetermined specificity 15.68%. Conclusion. Immunoglobulin prophylaxis has led to a significant reduction in the frequency of D-alloimmunization among pregnant women in the South Backa District over the last ten years. However, the incidence of anti-D antibodies is still significantly higher than in published data for developed countries. We also identified the other, less commonly present, clinically significant antibodies. There is a need to introduce uniform recommendations for immunohematological testing in pregnancy on the territory of the Republic of Serbia in accordance with modern requirements.

Vertebral compression fractures (VCFs), which are a complication of osteoporosis, often cause diagnostic and therapeutic difficulties. The aim of this study was to find association between the characteristics of VCFs and the symptomatic status of patients.The study involved a total of 437 women with diagnosed postmenopausal osteoporosis (193 with at least one compression fracture and 244 without VCFs). To identify VCFs, all patients underwent morphometry using dual-energy X-ray absorptiometry. Based on the history of VCFs, subjects were divided into two groups: with symptomatic (n=59) and asymptomatic (n=134) VCFs.Each patient had, on average, 2.03 ± 1.50 VCFs. Patients with VCFs were older [p0.001] and shorter [p0.001] than those without VCFs. VCFs located in the thoracic spine and the lumbar spine occurred with similar frequency (p=0.112). Multiple fractures in both spine segments (50.13%) were more frequent than fractures limited to only one section of the spine, either thoracic (22.76%) or lumbar (27.11%). The decreasing number of subjects was exponentially associated with the increasing number of VCFs (p0.001). Symptomatic patients compared to asymptomatic patients had a higher serum concentration of 25-hydroxyvitamin D, and lower serum activity of alkaline phosphatase (p0.01; p0.005, respectively). In the lumbar spin, the risk of symptomatic VCFs was more than twofold higher compared to asymptomatic VCFs (p0.001, OR=2.57, 95% CI: 1.57-4.19). Symptomatic status depended on the number of lumbar VCFs (p0.001, OR=2.47, 95% CI: 1.68-3.63), as well as higher T-score L1-L4 (p=0.009, OR=1.43, 95% CI: 1.09-1.88).Patients' symptomatic status depends on the location and number of VCFs, as well as T-score L1-L4.

BACKGROUND: Negative pressure wound therapy (NPWT) has been established over years for treatment of chronic and complex wounds. OBJECTIVE: Aim of this study was to investigate the effect NPWT on the microperfusion. METHODS: Prospective single centre analysis of patients treated with NPWT due to acute (ACUTE) wounds after fasciotomy or patients with chronic wounds (CHRONIC) due to a chronic limb threatening ischemia was performed. NPWT was conducted through a three days sequence with a negative pressure of –120 mmHg. Before after and during the entire period of therapy the microperfusion was assessed (O2C™, LEA Medizintechnik). RESULTS: Comparison of the perfusion values of 28 patients (CHRONIC/ACUTE 5/23, women/men 8/20) before and after the NPWT sequence showed a non-significant improvement in the CHRONIC group (supine position: p = 0.144, elevated position p = 0.068) and a significant decrease in the ACUTE group (supine position p = 0.012, elevated position p = 0.034). This effect could also been demonstrated during the NPWT over time (CHRONIC: supine position: p = 0.320, elevated position: p = 0.053, ACUTE: supine position: p = 0.021, elevated position: p = 0.012). CONCLUSION: Microperfusion measurements showed alterations and differences in wound bed perfusion of acute and chronic wounds; acute wounds tended to a decrease of blood flow, whereas this effect was not seen in chronic wounds in peripheral artery disease.

The Baha® Attract system can provide effective and stable hearing amplification for patients with microtia. Concurrent surgeries of auricle reconstruction and Baha® Attract implantation do not result in more soft tissue complications. The number of adverse events increased with the duration of implantation, even one year postoperatively. Benign skin evolutions, including skin thinning and erythema at the implant side, are commonly seen in Baha® Attract users. Implants are not necessarily removed when skin necrosis occurs in Baha® Attract users.

Objective Open and endovascular aortic repair may be complicated by aortic vascular graft or endograft infection (VGEI). Confirming the microbiological aetiology is a key element in providing the best available treatment to patients with a VGEI. The primary aim of this study was to describe the technique of direct aneurysm sac guided aspiration (DASGA) in determining the microbiological aetiology in a cohort of patients with VGEIs, and to report its diagnostic value. Methods This was a retrospective observational single centre study performed between the years 2011 to 2020 in Malmo, Sweden. Patients with a suspected aortic VGEI, where a DASGA was performed at the Vascular Centre, were included in the study. Results In total, 31 guided aspirations were performed in 27 patients (25 male [93%]; median age 77 years [range 57 – 82 years]). The combination of culture and 16S rRNA/18S rRNA gave a microbial aetiology in 25/31 (81%) DASGAs. Importantly, excluding three cases where infection was ruled out, this rate increases up to 89%. A polymicrobial aetiology was found in six (24 %) cases. The most common bacteria found were Cutibacterium spp. (n = 8) and Listeria monocytogenes (n = 4). In total, the dominant aetiology could be further characterised into normal gut flora (n = 12; 48%) or skin commensals (n = 8; 32%). No patients had persistent morbidity related to the DASGA. Conclusion DASGA can be used successfully to determine the microbiological aetiology of open and endovascular graft infections. This method appears to be safe, with a high success rate for confirming the microbiological aetiology of VGEIs, particularly if standard culturing methods are combined with 16S rRNA/18S rRNA. Finding the causative microbial aetiology is crucial, and in the vast majority of cases translumbar puncture can be used without serious complications.

OBJECTIVE To determine the PNI's prognostic effect of prognostic nutritional index (PNI) on operated papilla vateri tumor (PVT) survival. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Department of Medical Oncology, Ankara City Hospital, Ankara, Turkey, from April 2003 to December 2020. METHODOLOGY One hundred and eighty-two patients diagnosed with PVT were retrospectively screened. One hundred and twenty-six non-metastatic patients, who met the inclusion criteria and underwent curative surgery. PNIs were calculated using preoperative albumin and lymphocyte values and the cut-off value was taken and the two groups were compared in terms of overall survival. RESULTS The median age of the patients included in the study was 61 (36-88) years; 59.5% were males. The cut-off value was obtained using ROC-curves for the preoperative PNI values of 126 patients who underwent curative surgery. Patients were divided into two groups as PNI ≥38 and PNI

Objective To review our experience in the management of paediatric urethral strictures with buccal mucosal graft urethroplasty and its long term outcomes. Methods This was a retrospective analysis of a prospectively maintained data base between 2009–2019. Circumcised children with long segment urethral strictures (> 1.5 cm) were included. They were characterized as either peno-bulbar (PBS) or isolated bulbar strictures (IBS) based on a standardized protocol. All children underwent single stage dorsal onlay buccal mucosal graft urethroplasty by either the Kulkarni technique (PBS group) or the Barbagli technique (IBS group). All children were followed up at 3 months, then annually thereafter with flow rates at each visit. Success was defined as a flow rate > 10ml/sec with a bell-shaped curve and absence of need for any secondary procedures. Results 28 children underwent buccal mucosal graft uretheroplasty.16 children were diagnosed with PBS & 12 children with IBS. The median age was 7.5 years (2–17 years) in PBS and 5.5 years (3–10 years) in IBS. Iatrogenic injury was the commonest aetiology ie 71 % (20/28). Mean length of stricture was 4 cm (3–5.5 cm) in PBS and 2.5 cm (2–3.5 cm) in IBS. Median follow up was 96 months (24-120 months) in PBS and 90 months (36-120 months) in IBS. The success rate was 87.5% (14/16) in PBS and 83.3% (10/12) in IBS. Conclusion Single stage dorsal on lay buccal mucosal graft urethroplasty, ie Kulkarni and Barbagli techniques are safe and feasible in children with long segment urethral strictures with good long-term outcomes.

Introduction: Hypothyroidism is said to cause biliary stasis and impaired cholesterol metabolism thereby leading to the formation of gallstones. The incidence of thyroid dysfunction in patients with cholelithiasis has been studied in the past, but with inconclusive results. Hence, in this study, we have tried to assess if there is an association between thyroid profile and cholelithiasis with respect to age, gender, BMI and Lipid profile. Settings and Design: This study was a prospective observational study conducted at Mahatma Gandhi Medical College & Research Institute, Pondicherry. Methods and Material: Thyroid profile and Fasting Lipid Profile (FLP) was done for all patients, once diagnosed to have Cholelithiasis by USG Abdomen, attending the General Surgery OPD, above the age of 18. Final results were tabulated and a correlation of incidence of thyroid dysfunction with that of cholelithiasis was determined. Results: Out of the 60 patients, 63.3% were females and 36.7% were males. 63.3% of the patients were found to be euthyroid, 31.7% were found to be hypothyroid and only 5% were found to be hyperthyroid. Among the hypothyroid patients, 53.7% had subclinical hypothyroidism. Increasing age was significantly negatively associated (p=0.017) with the risk of developing hypothyroidism (reduced risk of 7%). As compared to males, females had a 19% reduced risk of developing hypothyroidism but this was however not statistically significant. Conclusions: This study concludes that there was no significant association between thyroid dysfunction and cholelithiasis, but there was a reduced risk of developing hypothyroidism in cholelithiasis patients with increasing age and of the female gender. However, further large group studies will be required to come to a final conclusion regarding the same.

Background: High right ventricular (RV) pacing burden may promote left ventricular dysfunction. Recently, His bundle pacing (HBP) has emerged as an alternative method to RV pacing that provides physiological ventricular activation by directly stimulating the conduction system. Methods: Consecutive 75 patients (male 61.3%, age 65 ± 14 yrs, preserved ejection fraction 53.8%, atrial fibrillation (AF) 56%) in whom HBP was attempted at our centre between May 2018 and September 2020 were included. Acute implant success rate, complications and mid-term outcomes were assessed. Results: Permanent HBP was acutely successful in 69 patients (92%). There were no acute procedure-related complications. Most common indication was AF with rapid ventricular response (38.7%) where HBP was performed in conjunction with atrioventricular node ablation. Median fluoroscopy time was lower during the second half of implants (6.35 (2.7 – 47) vs. 5.4 (1.3 – 13.6) minutes; p = 0.004). His capture parameters remained stable during the median follow-up of 193 (59 – 342) days. Eleven patients (11/69, 15.9%) with initially successful procedure experienced a significant rise in HBP threshold. Three patients (3/69, 4.3%) needed HBP lead revision or deactivation. Conclusion: Our initial experience indicates that HBP is feasible and safe in various pacing indications. Further randomized clinical trials with long-term follow-up are needed to provide the grounds for wider clinical application of this promising physiological pacing technique.

Purpose: Patients with chronic ureteric obstruction (CUO) are traditionally managed with polymer stents/nephrostomy. However, these are prone to failure and require regular exchange. This study eva...

We investigated the reliability of the 4Fusion® quadripodal memory staple in a consecutive series of 59 four-corner arthrodeses in a single centre. Forty-one patients (46 wrists) had a radiological and clinical assessment at a mean follow-up of 7.4 years. Thirteen patients (13 wrists) were lost to follow-up. Bone union was achieved in all but one patient. Seven patients were reoperated, six for device removal and one for nonunion. Most patients were satisfied, had a functional range of wrist mobility, good strength and were free of pain, comparable with the best previously reported series. Level of evidence: IV

Objective:The aim of this study is to evaluate clinical and surgical outcomes of children with subaortic stenosis, to determine the risk factors for surgery and reoperation and to compare isolated subaortic stenosis and those concomitant with CHDs.Methods:The study involved 80 children with subaortic stenosis. The patients were first classified as isolated and CHD group, and the isolated group was further classified as membranous/fibromuscular group. The initial, pre-operative, post-operative and the most recent echocardiographic data, demographic properties and follow-up results of the groups were analysed and compared. The correlation of echocardiographic parameters with surgery and reoperation was evaluated.Results:There was a significant male predominance in all groups. The frequency of the membranous type was higher than the fibromuscular type in the whole and the CHD group. The median time to the first operation was 4.6 years. Thirty-five (43.7%) patients underwent surgery, 5 of 35 (14%) patients required reoperation. The rate of surgery was similar between groups, but reoperation was significantly higher in the isolated group. The gradient was the most important factor for surgery and reoperation in both groups. In the isolated group besides gradient, mitral-aortic separation was the only echocardiographic parameter correlated with surgery and reoperation.Conclusion:Reoperation is higher in isolated subaortic stenosis but similar in membranous and fibromuscular types. Early surgery may be beneficial in preventing aortic insufficiency but does not affect the rate of reoperation. Higher initial gradients are associated with adverse outcomes, recurrence and reoperation.

Background Left bundle branch (LBB) pacing is a novel pacing technique which may serve as an alternative to both right ventricular pacing for symptomatic bradycardia and cardiac resynchronisation therapy (CRT). A substantial amount of data is reported by relatively few, highly experienced centres. This study describes the first experience of LBB pacing in a high-volume device centre. Methods Success rates (i.e. the ability to achieve LBB pacing), electrophysiological parameters and complications at implant and up to 6 months of follow-up were prospectively assessed in 100 consecutive patients referred for various pacing indications. Results The mean age was 71 ± 11 years and 65% were male. Primary pacing indication was atrioventricular (AV) block in 40%, CRT in 42%, and sinus node dysfunction or refractory atrial fibrillation prior to AV node ablation in 9% each. Baseline left ventricular ejection fraction was p = ns). Mean left ventricular activation time (LVAT) during LBB pacing was 81 ms and paced QRS duration was 120 ± 19 ms. LBB capture threshold and R‑wave sense at implant was 0.74 ± 0.4 mV at 0.4 ms and 11.9 ± 5.9 V and remained stable at 6‑month follow-up. No complications occurred during implant or follow-up. Conclusion LBB pacing for bradycardia pacing and resynchronisation therapy can be easily adopted by experienced implanters, with favourable success rates and safety profile.

Background and Aims: Idiopathic ventricular arrhythmia (IVAs) is defined as premature ventricular complexes (PVCs), nonsustained ventricular tachycardia or sustained ventricular tachycardia (VT) in the absence of obvious structural heart disease. Catheter ablation has become an established treatment strategy for wide varieties of idiopathic ventricular arrhythmias. The aim of this study is to report the efficacy and safety of catheter ablation of idiopathic ventricular arrhythmias, for the first time in Nepal. Methods: This is a retrospective observational descriptive study of all patients who underwent electrophysiological study and radiofrequency catheter ablation for IVAs from March, 2015 to February 2020 at Shahid Gangalal National Heart center (SGNHC). Results: Altogether 101 patients underwent an EP study with intent to ablations for idiopathic ventricular arrhythmias. In 13 patients, ventricular arrhythmias were not present on the procedure day and also could not be induced in the lab, therefore ablation was performed in 88 patients only. RVOT was the most common site of these arrhythmias comprising 51% of all cases, followed by fascicular VT (34%) and basal left ventricular IVAs (15%). Out of 88 patients, the acute success of 7 patients could not be assessed because of very infrequent PVCs. Out of remaining 81 patients, acute success achieved in 77 patients (95%). Recurrence occurred in 9 patients (10.7%) and 4 patients underwent repeat ablation giving rise to over clinical success during follow up in 78 patients (88.7%). There were two major complications, one pulmonary embolism and another cardiac tamponade both managed successfully. Conclusion: This single-center single operator study demonstrates that catheter ablation of idiopathic ventricular arrhythmias has a high success and low complication rate

The Paediatric Rheumatology International Trials Organisation (PRINTO) criteria for clinically inactive disease (CID) and their proposal for glucocorticoid tapering do not consider MRI findings, despite the growing use of MRI and development of reliable MRI scoring tools. We aim to evaluate how CID correlates with MRI scores and physician decision making. We retrospectively used the Juvenile Dermatomyositis Imaging Score (JIS) to score MRIs of all children with JDM over a 10-year period. Demographic, diagnosis, treatment and core set measures data were collected. Correlation between CID and JIS was assessed as well as correlation with the physician treatment decision. There were 25 patients with 59 follow-up episodes to analyse correlation between physician treatment decision and JIS; and 50 episodes for the CID category and JIS correlation. JIS was not significantly associated with the CID category but did correlate with the physician decision. No significant association was found between clinical decision and CID category. The JIS area under the ROC curve (AUC) was 0.80 (95% CI 0.62–0.99) with a score ≥ 8 to predict an escalation. JIS sensitivity and specificity were both 78% with accuracy of 78%, compared to only 67%, 46% and 49%, respectively, for the CID criteria. Clinical criteria alone are not sufficient to assess disease activity status. Clinical decision trends correlated to MRI findings but not PRINTO CID criteria. Multi centre prospective studies are needed to replicate our findings and establish how to best use MRI as a biomarker of disease activity.

Introduction Treatment of patients with Haemophilia A has improved significantly in recent years since the advent of novel therapeutic agents such as emicizumab. The low annualised bleeding rates associated with emicizumab have liberated many patients from the need for central venous access devices (CVAD). Optimal peri-operative management of CVAD removal is not currently known and there are no specific formal recommendations available. Aim We reviewed outcomes in a paediatric cohort in our centre undergoing CVAD removal without pre-operative factor or bypassing agent and reviewed the literature regarding port removal in patients on Emicizumab. Methods Ten male patients with severe Haemophilia A underwent CVAD removal without planned administration of factor concentrate or bypassing agent. Patients were monitored in hospital for 24 h with routine laboratory testing pre- and post-operatively. Results No significant bleeding episodes occurred in any patient, no patient required factor concentrate or bypassing agent and no patients were readmitted due to bleeding within 7 days of surgery. Conclusion We propose that, in the era of emicizumab, prophylactic factor administration pre-operatively for elective CVAD removal is not required in the majority of cases.

BACKGROUND Pancreatic exocrine insufficiency (PEI) is said to be associated with numerous conditions both within and outside the gastrointestinal (GI) system. The majority of research has been concerned with conditions that reduce the volume of functioning pancreatic tissue or prevent adequate drainage to the small bowel, such as chronic pancreatitis, cystic fibrosis, pancreatic cancer and pancreatic resection. However, the evidence base supporting an association with extra-pancreatic conditions, such as coeliac disease, diabetes mellitus and congestive cardiac failure, is heterogeneous. AIM To strengthen the evidence base by studying all previously reported associations with PEI in a large cohort of outpatients. METHODS A single-centre retrospective study was performed. General gastroenterology outpatients tested for PEI with faecal elastase-1 (FE1) were identified and information retrieved from the electronic patient record. PEI was defined as FE1 < 200 μg/g. Patients already taking pancreatic enzyme replacement therapy were excluded. Multiple imputation was used to handle missing data. Univariable logistic regression was used to study which presenting symptoms predicted PEI. Multivariable logistic regression was used to explore the relationship between all previously reported associations and PEI. RESULTS Of 1027 patients were included. 182 patients (17.7%) were diagnosed with PEI. Steatorrhoea [odds ratios (OR): 2.51, 95% confidence intervals (CI): 1.58-3.98] and weight loss (OR: 1.49, 95%CI: 1.08-2.06) were the only presenting symptoms that predicted PEI. Chronic pancreatitis (OR: 7.98, 95%CI: 3.95-16.15), pancreatic cancer (OR: 6.58, 95%CI: 1.67-25.98), upper GI surgery (OR: 2.62, 95%CI: 1.32-5.19), type 2 diabetes (OR: 1.84, 95%CI: 1.18-2.87), proton pump inhibitor therapy (OR: 1.87, 95%CI: 1.25-2.80) and Asian ethnicity (OR: 2.11, 95%CI: 1.30-3.42) were significantly associated with PEI in the multivariable analysis. None of the other historically reported associations with PEI were significant after adjustment for the other variables included in our multivariable analysis. CONCLUSION PEI is common in patients with chronic pancreatitis, pancreatic cancer, upper GI surgery and type 2 diabetes. Proton pump inhibitor therapy may also be associated with PEI or a false positive FE1.

To evaluate and compare the outcomes of two different surgical protocols for palatoplasty for midfacial growth in patients with cleft lip and palate. A retrospective observational cohort study was conducted in 80 patients with cleft lip and palate, who were divided into two groups. Group 1 comprised patients who underwent operation between 9 and 11 months of age using the Bardach two-flap technique without a palatal pushback. Group 2 comprised patients who had undergone operation between 18 and 20 months of age using either a Bardach two-flap technique with a palatal pushback or a von Langenbeck technique. Patient follow-up was done between 8 and 9 years of age when they reported to the centre for secondary alveolar bone grafting. Post-surgical cephalometric measurements were taken for midfacial growth analysis. Group 1 underwent palatoplasty at significantly younger ages than Group 2 (p 0.01). A statistically significant difference(p 0.01) was found between the two groups of patients on comparison of cephalometric parameters such as SNA, ANB, CoA, NperpA ANS-PNS, N-ANS, N-Me, Witt's (AO-BO). Group 2 had more positive cephalometric values as compared to Group 1, thereby implying that there was less incidence of midfacial hypoplasia in patients treated at the age of 18-20 months. Between the types of palatoplasty techniques within Group 2, i.e., Bardach two-flap and von Langenbeck, there was no statistical difference found in the post-opertative cephalometric values, i.e., SNA, ANB, CoA, ANS-PNS, N-ANS, N-Me, Witt's (AO-BO) except for Nperp-A, which showed a statistical difference (p = 0.03). Within the limitations of the study which is only a single center experience it seems that palatal closure should be carried out at 18-20 months of age for better midfacial growth, leading to decreased incidence of maxillary hypoplasia at a later stage in life. Repair at less than 18 months of age is also associated with mid-facial hypoplasia.

Introduction Management of malignant small bowel obstruction (mSBO) is challenging. The decision to perform an operation evaluates the perceived chance of success against a patient’s fitness for operation. The aim of this study was to characterise the mSBO patient population in a tertiary UK centre and assess the patient’s treatment pathway including use and effects of palliative surgery, total parenteral nutrition (TPN), Gastrografin and dexamethasone as well as preoperative stratification. Methods Patients were included if they had mSBO confirmed on computed tomography imaging due to a primary or metastatic neoplasm. Data were collected on pathway and management, and Cox proportional hazard methods were utilised to observe effects on survival. Results Ninety-four patients were included, with 104 inpatient episodes. Mean age was 67.4 (SD 13.7), with 57 (60.6%) females. Most (89.4%) had only one admission for mSBO. Eighty-four (89.4%) patients died over the ten-year period, 18 (17.3%) within 30 days of admission. Fifty patients (53.1%) underwent operative management: 70% bypass, 24% stoma formation and 6% open-close laparotomies. Log rank testing of survival probability analysis was significant (p = 0.00018), with 50% survival probability at 107.32 days for operative management and 47.87 days for non-operative. Discussion and Conclusion Operative management forms part of the treatment pathway for a significant proportion of patients with mSBO, offering a survival benefit, though quality of survival is not known. Case selection is good, with few open-close laparotomies. Trials of non-operative interventions such as Gastrografin and dexamethasone are not utilised fully.

Objective Different procedures have been described to treat superior canal dehiscence. The present study aims to describe the results obtained with middle fossa approach, transmastoid approach, and round window reinforcement in a large series of patients. Methods and Design In this single‐center retrospective study, we report the results of the procedures performed between 2006 and 2019 using the three main surgical approaches, middle fossa approach (MFA), transmastoid approach (TMA), and round window reinforcement (RWR). The outcome on cardinal cochlear and vestibular symptoms, audiometric results, and changes in cervical vestibular evoked myogenic potentials (cVEMPs) were analyzed. The patients were also interviewed 12 months to 13 years post‐treatment to establish their overall satisfaction following surgery. Results Sixty‐three patients were divided into three groups: 42 MFA; 12 RWR; 9 TMA. Postsurgical control rates exceeded 80% for the majority of symptoms in the MFA and TMA groups, and ranged from 11.1% to 83.3% for the RWR group. Over 90% of MFA or TMA patients and 60% of the RWR cohort were satisfied overall with their treatment. Hearing thresholds were intact following surgery in the MFA and TMA groups. There was one case of profound postoperative deafness in the RWR group. Conclusion MFA and TMA are both safe and effective techniques in the treatment of disabling SSCD. Since MFA is the more invasive technique, we suggest that TMA should be proposed as first‐line treatment, temporal bone anatomy permitting. RWR outcomes are more variable in term of symptomatic control, and this option could be offered to patients at risk under general anesthesia. Level of evidence Level 4 evidence.

The objective of this retrospective single centre study was to determine whether different enteric reconstruction methods and adjuncts confer a benefit after in situ reconstructions (ISRs) of graft aorto-enteric erosion (AEnE) and fistula (AEnF).Primary endpoints were in hospital mortality and AEnE/F recurrence. Survival was estimated using the Kaplan-Meier method and explanatory factors were searched for using uni- ± multivariable Cox regression analysis. In 2013, a multidisciplinary team meeting was convened and since then the primary operator has always been a senior surgeon.Sixty-six patients were treated for AEnE (n = 38) and AEnF (n = 28, 42%) from 2004 to 2020. All patients with AEnF presented with gastrointestinal bleeding (vs. 0 for AEnE; p.001). Signs of infection were seen in 50 patients (76% [37 for AEnE vs. 13 for AEnF]; p.001). Referrals for endograft infection increased over time (n = 15, 23%; one before 2013 vs. 14 after; p = .002). Most patients underwent complete graft excision (n = 52, 79%) with increasing suprarenal cross clamping (n = 21, 32%; four before 2013 vs. 17 after; p = .015). Complex visceral reconstructions decreased over time (n = 31, 47%; 17 before 2013 vs. 14 after; p = .055), while "open abdomens" (OAs) increased (one before 2013 vs. 22 after; p.001), reducing operating time (p = .012). In hospital mortality reached 42% (n = 28). Estimated survival reached 47.6% (95% confidence interval [CI] 35.0 - 59.1) at one year and 45.6% (95% CI 33.0 - 57.3) at three years and was higher for AEnE than for AEnF (log rank p = .029). AEnE/F recurrence was noted in 12 patients (18%). Older age predicted in hospital mortality in multivariable analysis (p = .034). AEnE/F recurrence decreased with the presence of a primary senior surgeon (vs. junior; p = .003) and OA (1 [4.4%] vs. 11 [26%] for primary fascial closure; p = .045) in univariable analysis.Mortality and recurrence rates remain high after ISR of AEnE/F. Older age predicted in hospital mortality. Primary closure of enteric defects ≤ 2 cm in diameter reduced operating time without increasing the recurrence of AEnF.

PURPOSE To study if an additional virtual interactive epilepsy education session improves post-test epilepsy knowledge scores more than providing digital educational material alone in persons with epilepsy (PWE) and caregivers. METHODS In a single centre, open labelled, randomised controlled trial, PWE and caregivers were randomised to receive digital epilepsy educational material alone or an additional virtual interactive epilepsy session along with the digital educational material. Pre-test knowledge scores were compared with post-test knowledge scores. A difference between the post-test scores in the two arms was the primary outcome. This was assessed one week after the epilepsy education had been received. Secondary outcomes were the difference between the two arms in quality of life and breakthrough seizure frequencies at the end of one month. RESULTS A total of 130 participants (PWE+caregivers) were randomised of which 66 were in the control arm and 64 in the intervention arm. Baseline demographic and epilepsy characteristics were comparable in both arms except for the higher age of PWE in the intervention arm. Post-test knowledge scores improved significantly from the pre-test knowledge scores in both control and intervention arms (p

Summary: Background: Pancreatic cystic lesions (PCLs) are being more frequently dia­gnosed and some have the potential for malignant transformation. The decision for performing EUS-FNA and indicating surgery remains challenging. Aims: To evaluate the feasibility and dia­gnostic yield of EUS-FNA, and in patients undergoing surgery to compare results of EUS-FNA with the resection histology. Methods: A retrospective observational study in patients undergoing EUS-FNA for PCLs. We assessed morphological risk features: solid component, a mural nodule >5 mm, dilated pancreatic duct >5 mm, lesion size >4 cm. The mucinous content was defined macroscopically by positive string test/thick mucin and/or by high CEA (>100 ng/ml) or low glucose (

Pharmacological therapy is mostly employed in the management of supraventricular tachyarrhythmias in different part of the world including Bangladesh. However, Radiofrequency catheter ablation has been found to be highly effective and safe in the treatment of such tachyarrhythmias. Objective: The current study is aimed at sharing our experiences of 842 patients who presented with Supraventricular tachycardias and were diagnosed by EPS and treated with Radiofrequency catheter ablation. Methods: This descriptive study has been carried out in the cardiac electro physiology Department of NICVD, Dhaka, Bangladesh from 2nd January 2015 to 31st December, 2020. Electrophysiology study(EPS) was carried out to identity and diagnose the mechanism of different SVTs in 842 consecutive patients. RF catheter ablation was used to interrupt the tachycardia circuit. Results: Out of a total 842 patients who underwent Electrophysiology study, 435 were found to have atrioventricular nodal re-entry tachycardia (AVNRT) as underlying mechanism and 391 were having accessory pathway responsible for the reentry mechanism; of these accessory mediated tachycardia, 250 patients were manifested accessory pathway (WPWS); 141 were concealed accessory pathway (out of them 365 were presented with orthodromic and 26 as antidromic reciprocating tachycardia); moreover among the accessory pathway 231 patients were found having left sided accessory pathway whereas 155 having right sided pathway; 12 patients were having focal atrial tachycardia and 4 were found atrial flutter as the underlying cause for SVT. Radiofrequency catheter ablation was used with an overall success rate of 95%, recurrence rate of 2% without any significant complication. Complication: One patient developed pulmonary thrombo-embolism, 6 patients developed DVT of right lower limb, 4 patients developed complete heart block. Conclusion: RF catheter ablation is safe and highly effective mode of treatment of different types of supraventricular tachyarrhythmias which is emerging and becoming popular in our country.

BACKGROUND Dual energy computed tomography (DECT) is a new method of computed tomography (CT) imaging which allows to determine stone composition in addition to assessing stone morphology. The purpose of this study was to evaluate the role of dual energy CT (DECT) preoperatively to assess the composition of urinary stones and to compare it with post-operative in vitro qualitative chemical analysis as reference standard. METHODS Forty patients (18 male and 22 female) who presented with symptoms of renal stones in the department of urology were included in the study. All 40 patients who were diagnosed to have renal stones clinically and by ultrasonography (USG) kidney, ureter and bladder (KUB) region were subjected to dual energy CT. The stone composition assessed in vivo using DECT preoperatively and in vitro by chemical analysis post operatively after stone extraction by surgical procedure. The results were compared by statistical analysis. Sensitivity, specificity and positive predictive value (PPV) were calculated and descriptive study done using Statistical Package for Social Sciences (SPSS) 20.00 version. Data was analysed by comparing it with correlative qualitative chemical analysis. RESULTS In our study, in vivo analysis using DECT showed most common type of stone was calcium oxalate seen in 20 cases compromising 50 % of total cases. Next common stone type was uric acid stone (22.5 %) followed by cysteine (17.5 %) and calcium hydroxyapatite (10 %) respectively. When the same stones were subjected to ex vivo chemical analysis, one of the calcium oxalate stone came out to be calcium phosphate and one of the cysteine stone came out to be mixed stone. Thus, out of 40 stones, 38 stones were found to have the same result in ex vivo chemical analysis as that of in vivo analysis by dual energy CT. Hence, accuracy of dual energy CT in diagnosis of renal stones was found to be 100 % with CI 91.19 % - 100 %. CONCLUSIONS With dual energy CT, it is possible to determine the composition of renal calculi in vivo non-invasively (with specificity of 100 % in our present study). Therefore, this helps in deciding the modality of treatment pre-operatively whether the stone is amenable to medical management (e.g., Uric acid stones) or requires extracorporeal shock wave lithotripsy (ESWL) or surgical intervention can be determined preoperatively. This helps to reduce the unnecessary financial burden and is found to be time saving.

Introduction: Sexual education is an important step to prevent unwanted pregnancy, abortions and sexual transmitted diseases (STDs) in adolescent. Assessment of the sexual health knowledge and the attitude towards premarital sexual activity are essential to fill in this gap of knowledge. Objective: The objective of this study was to examine the knowledge on the sexual health and attitude towards premarital sexual activity among the sexually abused adolescent. Methods: A cross-sectional study was conducted among 88 female teenagers who were admitted to Hospital Universiti Sains Malaysia for sexual abuse. Using a self-administered validated Malay questionnaire, participants were guided to answer the question on knowledge and attitude. The attitude was categorized to a permissive and non-permissive attitude. Simple and multiple binary logistic regression were used to analyze the associated factors with the attitude. Result: The lowest percentage of correct responses included: penile discharge during ejaculation contains sperm (5.7%), pregnancy may not occur if having sexual intercourse once only (26.1%), having vaginal washing after sexual intercourse prevents pregnancies (19.3%). Forty-one (48.0%) of participants had a permissive attitude whereas forty-seven (53.4%) had a non-permissive attitude toward premarital sexual activity. Simple and multiple logistic regressions did not reveal any significant associated factors. Conclusion: The sexual health knowledge among sexually abused children was inadequate and they were at risk of permissive attitude toward premarital sexual activity. We could not identify any factors related to the permissive attitude in our study.

PURPOSE To evaluate efficacy and safety of the iStent inject combined with phacoemulsification in Asian eyes with normal-tension glaucoma (NTG) up to 12 months after surgery. STUDY DESIGN Retrospective case series. METHODS Retrospective case series of eyes undergoing surgery from April 2017 to August 2019. Outcome measures included intraocular pressure (IOP), number of topical glaucoma medications and adverse outcomes. Data were retrieved from the post-operative day 1 (POD1), week 1 (POW1), month 1 (POM1), month 3 (POM3), month 6 (POM6) and month 12 (POM12) timepoints. Data were analysed at each timepoint for eyes with available clinical data at that visit. Subgroup analysis was performed for a consistent cohort which included only eyes with data at all six follow-up timepoints. RESULTS Data from 91 eyes in the collective subject group was analysed. Majority of subjects were male (53, 58.2%) and Chinese (79, 86.8%). Mean age was 73.2 ± 7.2 years. Pre-operatively, mean IOP was 14.3 ± 3.0 mmHg and mean number of medications was 1.5 ± 0.8. Significant IOP reduction was observed at all timepoints except POW1 and POM12. The number of medications was reduced at all timepoints (p

Background: Kidney transplantation in India is steadily increasing with advancement in medicines and surgical expertise. Subjects with kidney disease have spectrum of pulmonary pathologies but little is known regarding status on pulmonary function after kidney transplantation. Method: 149 kidney transplant recipients between 18 to 60 years of age, having stable graft function and more than 6months of post-transplant duration were included in the study. Forced vital capacity (FVC), forced expiratory volume in first second (FEV1), the ratio of FEV1/FVC and peak expiratory flow rate (PEFR) were evaluated. Result: 11 (7.4%) had a restrictive ventilatory impairment, none had obstructive lung function. FEV1 and FVC were lower among subjects with high waist circumference, over weight and obese. FEV1/FVC ratio were lower in subjects with comorbidities or physical inactivity. Conclusion: Restrictive lung functions present in few kidney transplant recipients. High waist circumference, over weight, obesity, comorbidity and physical inactivity alters pulmonary functions in kidney transplant recipients. KEY WORDS: Kidney transplantation, pulmonary function test, anthropometry, physical activity, comorbidity.

Objectives: The aim of this study was to analyze clinical manifestations, epidemiology and laboratory parameters of B. henselae infection among children treated at the University Hospital for Infectious Diseases “Dr. Fran Mihaljević”, Zagreb from January 2014 until June 2019. Materials and methods: We retrospectively analyzed the epidemiology, clinical and laboratory characteristics among children with positive indirect immunofluorescence assay for B. henselae IgM and IgG or positive B. henselae polymerase chain reaction from lymph node aspirate. Results: A total of 104 patients, 47 (45,1%) female and 57 (54,8%) male were enrolled. The median age was 9,7 (range, 1,1 to 17,3 years). A history of cat contact was present in 101 (97,1%) children. Acute infection was serologically confirmed in 87 (83,6%), in 5 (4,8%) with PCR while both methods were positive in 12 (11,5%) patients. The presentation on B. henselae infection were regional lymphadenopathy , disseminated disease, encephalopathy and fever of unknown origin. Suppurative inflammation was the most common complication in patients with lymphadenopathy 12/92 (13%). Full recovery was the most frequent outcome (96,1%). Conclusion lesion: B. henselae infection among children is usually a mild disease presented as regional lymphadenopathy. Serology and polymerase chain reaction are useful tests for diagnosis. Treatment duration and choice of therapy depend on clinical manifestation and developed complications.
