Gender differences in the assessment, decision-making and outcomes for ventricular assist devices and heart transplantation: An analysis from a UK transplant center.

PURPOSE: There are marked gender differences in all etiologies of advanced heart failure. We sought to determine whether there is evidence of gender-specific decision making for transplant assessments, and how gender effects outcomes. METHODS: Retrospective analysis of adult heart transplant assessments at a single UK center between April 2015 and March 2020. RESULTS: Females were 32% of referrals (N = 137 females, 285 males), with marked differences between diagnoses - 11% ischemic and 43% of adult congenital. Females were younger, shorter, weighed less, and had lower pulmonary pressures. Females were much less likely to receive a ventricular assist device (13%). Blood type "O" females were relatively more likely compared to males to receive a transplant (45%). Comparing males and females who received a ventricular assist device, both had similar levels of high pulmonary pressures, indicating consistent decision-making based on hemodynamics to implant a device. Overall survival was better for females (in noncongenital patients), and this was due to female patients who were not accepted for transplant or a ventricular assist device being more often "too well for transplant," rather than in males when they were more often "unsuitable." CONCLUSIONS: Marked gender differences exist at all stages of the heart transplant assessment pathway. Appropriate decision-making based on clinical grounds is shown with less transplants in male blood type "O"s and hemodynamic criteria for ventricular assist device implantation in both genders. Further studies are needed to determine if there is a wider community bias in advanced heart failure treatments for females.

Practice and enforcement of national Hospital Waste Management 2005 rules in Pakistan.

BACKGROUND: Hospital waste management (HWM) rules in Pakistan were issued in 2005. Despite a decade of enactment, adherence to HWM 2005 rules has been inconsistent and systematic assessment of adherence using a World Health Organization (WHO)-recommended questionnaire has not been done in all teaching hospitals of Peshawar District. AIMS: This study assessed the adherence to HWM 2005 rules by tertiary care teaching hospitals of Peshawar District with respect to HWM personnel, policy and practices. METHODS: Pretested structured questionnaires based on WHO recommendations were used to survey all teaching hospitals of Peshawar District from January to March 2015. Data were also collected on HWM infrastructure and processes from 1 randomly selected medical, surgical, paediatric, and obstetrics/gynaecology unit in each hospital. Besides descriptive statistics, public and private hospitals were compared using Fisher's exact and Wilcoxon rank-sum tests. RESULTS: Most surveyed hospitals lacked formal HWM plans (70%), written procedures (80%), related job descriptions (80%) or records (90%). Many hospitals neither had trained HWM supervisors (56%) nor did they organize formal HWM trainings for new staff (40%). None of the hospitals followed waste segregation and colour coding. When compared to national HWM 2005 rules, multiple gaps in appropriate transportation, storage and disposal were found with no statistically significant difference between public and private hospitals. CONCLUSIONS: Serious gaps in adherence to HWM 2005 rules exist in surveyed hospitals. With recent devolution of environmental function, the Government of Khyber Pakhtunkhwa should enact provincial HWM rules (and ensure their implementation) to facilitate effective HWM practice across provincial healthcare facilities.

MoS2 Field-Effect Transistor Performance Enhancement by Contact Doping and Defect Passivation via Fluorine Ions and Its Cyclic Field-Assisted Activation.

MoS2-based field-effect transistors (FETs) and, in general, transition metal dichalcogenide channels are fundamentally limited by high contact resistance (RC) and intrinsic defects, which results in low drive current and lower carrier mobilities, respectively. This work addresses these issues using a technique based on CF4 plasma treatment in the contacts and further cyclic field-assisted drift and activation of the fluorine ions (F-), which get introduced into the contact region during the CF4 plasma treatment. The F- ions are activated using cyclic pulses applied across the source-drain (S/D) contacts, which leads to their migration to the contact edges via the channel. Further, using ab initio molecular dynamics and density functional theory simulations, these F- ions are found to bond at sulfur (S) vacancies, resulting in their passivation and n-type doping in the channel and near the S/D contacts. An increase in doping results in the narrowing of the Schottky barrier width and a reduction in RC by ∼90%. Additionally, the passivation of S vacancies in the channel enhances the mobility of the FET by ∼150%. The CF4 plasma treatment in contacts and further cyclic field-assisted activation of F- ions resulted in an ON-current (ION) improvement by ∼90% and ∼480% for exfoliated and CVD-grown MoS2, respectively. Moreover, this improvement in ION has been achieved without any deterioration in the ION/IOFF, which was found to be >7-8 orders.

Reduction of medication costs after detoxification for medication-overuse headache.

OBJECTIVE: To examine whether detoxifying patients with medication-overuse headache can reduce long-term medication costs. BACKGROUND: Direct costs of medications in medication-overuse headache have been reported to be very high but have never been calculated on the basis of exact register data. Long-term economic savings obtained by detoxification have never been investigated. METHODS: We conducted a registry-based observational retrospective follow-up study on 336 medication-overuse headache patients treated and discharged from the Danish Headache Center over a 2-year period. By means of the Danish Register of Medicinal Product Statistics, we collected information on the costs and use of prescription-only medication 1 year before admission and 1 year after discharge from Danish Headache Center. RESULTS: The average medication costs per patient per year decreased with 24%, from US$971 before treatment to US$737 after (P = .001), and the average medication use decreased with 14.4% (P = .02). Savings were most pronounced for patients overusing triptans. In this group, the average medication costs per patient per year decreased with 43% (P < .001), while the average triptan use decreased with 38% (P < .001). CONCLUSIONS: The study demonstrates that detoxification of medication-overuse headache at a tertiary headache center has a long-lasting effect on the medication costs and use, in particular among patients overusing triptans. The results may not be generalizable to all countries and may be sensitive to the costs of triptans.

Safety and efficacy of treatment for chronic hepatitis C during pregnancy: A prospective observational study in Srinagar, India.

In India, the estimated prevalence of antenatal HCV infection is 0.3%-2.8%, and the rate of mother-to-child transmission has been estimated at 5%-15%. HCV treatment during pregnancy could reduce maternal complications from HCV infection, prevent transmission to the infant, and reduce HCV infection overall in women of childbearing age. However, there are limited studies of HCV treatment with direct-acting antiviral medications during pregnancy, and therefore, direct-acting antivirals are not commonly used for treatment during pregnancy. We describe our institutional experience in this prospective observational study over 3 years at the Sher-I-Kashmir Institute of Medical Sciences, Srinagar, India. Patients with chronic hepatitis C in pregnancy were enrolled and treated with ledipasvir and sofosbuvir after the first trimester. Primary end points were sustained virologic response at 12 weeks, adverse drug reactions, and congenital malformation of the infant. The secondary end point was the transmission of HCV infection to the infant. We enrolled 26 patients in our study. The mean age was 28 years (range of 21-36 y). All patients were noncirrhotic and treatment-naive. The mean HCV RNA before treatment was 9.2 ×10^5 IU/ml. Among the enrolled patients, 19 (73%) were genotype 3, 5 (19%) were genotype 1, and 2 (8%) were genotype 4. All patients achieved sustained virologic response at 12 weeks. Some patients reported nausea (27%), headache (27%), and fatigue (16%). All patients had institutional delivery, and no infant was found to have congenital malformations. No child had detectable HCV RNA at 6 months of age. To our knowledge, we here report results from the largest cohort of pregnant women treated for HCV infection globally. Ledipasvir and sofosbuvir were well tolerated and highly effective for both HCV cure in the mother and elimination of mother-to-child transmission. No congenital abnormalities were detected in our cohort. Elimination of mother-to-child transmission is urgently needed, and this study has shown that treatment of HCV during pregnancy may be a pragmatic approach for the greater benefit of both mother and the newborn.

ST elevation myocardial infarction and kidney transplant: A large cohort study: STEMI and renal transplant.

BACKGROUND: The literature on outcomes of ST-elevation myocardial infarction (STEMI) amongst kidney transplant recipients (KTR) is limited. OBJECTIVE: To study the outcomes of STEMI among KTR. METHODS: Data from the national readmissions database (NRD) sample that constitutes 49.1% of the stratified sample of all hospitals in the USA were analyzed for hospitalizations with STEMI among KTR for the years 2012-2018. Complications associated with STEMI were extracted using International Classification of Diseases codes. RESULTS: A total of 588,668 index KTR hospitalizations (mean age 57.67±14.22 years; female 44.5%) of which 3,496 (0.59%) had STEMI were recorded in the NRD for the years 2012-2018. A total of 11,676 (1.98%) patients died during the hospitalization. In-hospital mortality among STEMI was higher, 465 (13.3%), than without-STEMI 11,211 (1.92%). Among the complications, mechanical complications occurred among 1.0% vs 0.02%, cardiogenic shock 10.6 vs 0.3%, ventricular arrythmias 8.3% vs 0.8%, conduction block 6.9% vs 2%, stroke 4.1% vs 1.9%, and acute kidney injury 31.6% vs 28.3% among STEMI and without-STEMI respectively. Among coronary procedures, coronary angiography was performed among 1,999 (57.2%) of which 1,777 (50.8%) had percutaneous coronary intervention (PCI). On coarsened exact matching of baseline characteristics, PCI was less likely associated with mortality, odds ratio 0.39 (95% confidence interval 0.24-0.64; p=0.0002). The trends of mortality among STEMI were steady (p-trend 0.11). PCI trend increased (p-trend 0.008) and incidence of STEMI decreased over the study years 2012 (0.66%)-2018(0.474%). A total of 84,810 (14.4%) patients were readmitted in 30 days of which 696 (20%) patients were among the STEMI subgroup. CONCLUSION: STEMI is not an uncommon complication among KTR and is associated with significant mechanical complications. Improvement in cardiovascular risk factors might improve the STEMI rates among KTR.

Association of dementia and patient outcomes among COVID-19 patients: A multi-center retrospective case-control study.

Background: We conducted a retrospective cohort study on COVID-19 patients with and without dementia by extracting data from the HCA Healthcare Enterprise Data Warehouse between January-September 2020. Aims: To describe the role of patients' baseline characteristics specifically dementia in determining overall health outcomes in COVID-19 patients. Methods: We grouped in-patients who had ICD-10 codes for dementia (DM) with age and gender-matched (1:2) patients without dementia (ND). Our primary outcome variables were in-hospital mortality, length of stay, Intensive Care Unit (ICU) admission, ICU-free days, mechanical ventilation (MV) use, MV-free days and 90-day re-admission. Results: Matching provided similar age and sex in DM and ND groups. BMI (median, 25.8 vs. 27.6) and proportion of patients who had smoked (23.3 vs. 31.3%) were lower in DM than in ND patients. The median (IQR) Elixhauser Comorbidity Index was higher in dementia patients 7 (5-10) vs. 5 (3-7, p < 0.01). Higher mortality was observed in DM group (30.8%) vs. ND group (26.4%, p < 0.01) as an unadjusted univariate analysis. The 90-day readmission was not different (32.1 vs. 31.8%, p = 0.8). In logistic regression analysis, the odds of dying were not different between patients in DM and ND groups (OR = 1.0; 95% CI 0.86-1.17), but the odds of ICU admissions were significantly lower for dementia patients (OR = 0.58, 95% CI 0.51-0.66). Conclusions: Our data showed that COVID-19 patients with dementia did not fare substantially worse, but in fact, fared better when certain metrics were considered.

Intrabiliary rupture of hepatic hydatid cyst: multidetector-row CT demonstration.

Rupture of a hydatid cyst into the biliary tract, also known as cystobiliary communication, is the most common complication of hepatic hydatid cyst. This may lead to obstructive jaundice, pancreatitis, cholangitis, and sepsis with high mortality. Imaging plays an important role in the preoperative diagnosis of this condition which facilitates its management. We studied six patients with rupture of hepatic hydatid cyst into a large bile duct in whom multidetector-row CT (MDCT) suggested the diagnosis. The imaging findings included a single hepatic cyst less than 10 cm in diameter in all the cases; interruption of the cyst wall adjacent to a bile duct signifying cyst-bile duct communication was seen in five patients. The common bile duct was dilated in all the patients, with linear membranes in four and diffuse irregular high dense intrabiliary material observed within the common bile duct in two of them. Intrahepatic ducts were dilated in all the six cases and two patients showed linear dense contents within distended gallbladder. Subcapsular and intrathoracic rupture was associated in one patient each. MDCT demonstration of hydatid cyst in the liver together with a dilated common bile duct and distended gallbladder containing high density hydatid material suggest rupture of the cyst into biliary tree. MDCT enhances demonstration of the dilated common bile duct with hydatid material inside. The diagnosis is reinforced by the demonstration of the cystobiliary communication itself.

Outcome of hepatitis C patients in a community with predominant genotype 3 with standard-of-care treatment before and after advent of direct-acting antivirals: A retrospective-cum-prospective study.

BACKGROUND AND OBJECTIVE: Chronic hepatitis, cirrhosis, and hepatocellular carcinoma are mainly caused by hepatitis C infection. It is a worldwide predominant pathogen and is one of the main causes of healthcare problem in Asia. In the last few decades, there has been a considerable change in the treatment regimen for hepatitis C virus. The objective of this research was to relate the treatment response with sustained viral response in various therapies which have been the standard of care from time to time. MATERIALS AND METHODS: This hospital-based, retrospective-cum-prospective research span over a period of 2 years; we enrolled hepatitis C patients who attended the Department of Gastroenterology and Hepatology, Government Medical College, Srinagar, since June 2015 till May 2017. Subsequently, the database was prepared, containing all the relevant information about these patients. CONCLUSIONS: (i) In retrospective group: The overall efficacy (sustained viral response at 24 weeks [SVR-24]) of pegylated interferon a2a and ribavirin regimen was 90.96%. (ii) In prospective group: The efficacy (SVR) of different regimens was found to be as: sofosbuvir + ribavirin + daclatasvir (SVR-24, 83.33%); sofosbuvir + ribavirin (SVR-12, 94.57%); and sofosbuvir + daclatasvir (SVR-12, 98.00%).

Initial conservative management strategy of HeartWare left ventricular assist device thrombosis with intravenous heparin or bivalirudin.

INTRODUCTION AND OBJECTIVES: Pump thrombosis is a serious left ventricular assist device complication, though there are no guidelines regarding its treatment. The main aim of this study was to describe a strategy of intravenous anticoagulation as the initial treatment in these patients and then to compare intravenous heparin with bivalirudin. METHODS: All consecutive patients who received a HeartWare left ventricular assist device from July 2009 to March 2019 were retrospectively analysed. Patients developing a pump thrombosis were selected, and treatment, outcomes and complications were recorded. RESULTS: During this period of time (116 months), 220 patients underwent HeartWare left ventricular assist device implantation and 57 developed pump thrombosis, with an incidence rate of first pump thrombosis of 0.17 events per patient-year of support (incidence rate of all episodes of pump thrombosis: 0.30 events per patient-year of support). All the patients were initially treated medically, predominantly with either intravenous heparin (n = 26) or bivalirudin (n = 16). Patients treated with bivalirudin during the first pump thrombosis episode had less subsequent re-thrombosis episodes (18.7% vs 57.7%, p < 0.05). In addition, percentage time in therapeutic range was greater for bivalirudin compared with heparin (68.5% ± 16.9% vs 37.4% ± 31.0%, p < 0.01). During the first pump thrombosis episode, 26.3% of the patients needed surgery (left ventricular assist device exchange (n = 8), transplant (n = 6) or decommissioning (n = 1)). The overall survival at 1 year was 61.4%, and there was no significant difference in survival. CONCLUSION: Left ventricular assist device thrombosis is a serious life-threatening complication; hence, we propose an initial conservative management of pump thrombosis with enhanced intravenous anticoagulation with either intravenous heparin or bivalirudin, with surgery reserved for refractory cases.

Neutrophil to Lymphocyte Ratio Is Related to Thrombotic Complications and Survival in Continuous Flow Left Ventricular Assist Devices.

Left ventricular assist devices (LVADs) have become an established treatment for advanced heart failure, although with long-term support these patients are potentially exposed to serious complications. Our purpose was to assess the role of the neutrophil to lymphocyte ratio (NLR) in LVAD complications and to evaluate if higher values of NLR after 4-6 months on LVAD support (NLR 4_6m) are associated with worse prognosis. All consecutive patients who received a HeartWare LVAD (N = 188, age 50 ± 13 years), as bridge to transplant from December 2009 to January 2018 were included. Neutrophil to lymphocyte ratio was recorded pre-LVAD, post-LVAD, after 4-6 months on support and in case of a first adverse event to occur after the 4-6 months NLR was recorded. Median NLR values were pre-LVAD 4.26 (interquartile range [IQR], 3.1-6.9), at 1 day postoperative 11.6 (IQR, 8.3-16.6), and NLR 4_6m 4.4 (IQR, 3.0-6.4) (p < 0.001). Neutrophil to lymphocyte ratio increased significantly when patients had an infection, stroke, or pump thrombosis, as compared with the NLR 4_6m (all p < 0.05). Patients with NLR 4_6m ≥ median had higher rates of stroke and mortality. Survival time was shorter among patients with NLR 4_6m ≥ 4.4 (log-rank test p = 0.006). Neutrophil to lymphocyte ratio 4_6m was found to be predictive of increased mortality (area under the curve of 0.62, p = 0.007). After multivariate analysis, NLR 4_6m remained independently associated with increased mortality (hazard ratio [HR] 1.67; 95% confidence interval [CI], 1.03-2.7; p = 0.037). Neutrophil to lymphocyte ratio 4_6m values significantly increase in association with adverse events on LVAD support and are independently associated with mortality. This association suggests presence of inflammation adversely affects LVAD outcomes.

Pharyngeal Obturator Prosthetic Rehabilitation of Velopharyngeal Insufficiency.

Congenital or acquired defects of soft palate cause physical, functional and psychological disabilities. Surgical closure or prosthetic rehabilitation are the two treatment modalities. If surgery is contraindicated, prosthetic rehabilitation is the alternative treatment option. Pharyngeal obturator prosthesis provides adequate closure of the velopharyngeal insufficiency. In this case report, a young patient is treated for velopharyngeal insufficiency with pharyngeal obturator as the patient had refused to undergo surgical closure. The prosthesis was successfully fabricated and was evaluated for proper functioning. It improved speech, deglutition and psychological well-being of the patient.

The use of folic acid in dengue: has it any value?

Folic acid is used in dengue patients. Our study aims to compare the duration of recovery of thrombocytopenia in patients with dengue infection who received folic acid and those who did not. We retrospectively reviewed the medical records of adult patients admitted over six years with a diagnosis of dengue. Of 2216 patients, 1464 fulfilled the inclusion criteria. Group A were those patients who received folic acid and group B were those who did not. A total of 1322 (90.3%) patients received folic acid. The mean time period required for platelets to double the nadir was 1.7 (±2.2) days in both groups A and B ( P = 0.89). In conclusion, there is no significant difference in the recovery of thrombocytopenia in patients with dengue fever who received folic and those who did not receive folic acid.

Aortic Valve Replacement with a Conventional Stented Bioprosthesis versus Sutureless Bioprosthesis: a Study of 763 Patients.

OBJECTIVE: The aim of this retrospective study was to compare early postoperative outcomes after aortic valve replacement (AVR) with sutureless bioprostheses and conventional stented bioprostheses implanted through median sternotomy. METHODS: From January 2011 to December 2016, 763 patients underwent aortic valve replacement with bioprostheses; of these, 139 received a Perceval S sutureless valve (Group A) and 624 received a Perimount Magna Ease valve (Group B). These groups were further divided into A1 (isolated Perceval AVR), A2 (Perceval AVR with coronary artery bypass grafting [CABG]), B1 (isolated conventional stented bioprosthesis), and B2 (conventional stented bioprosthesis + CABG). RESULTS: Patients in Group A were older (mean 74 years vs. 71 years; P<0.0001), predominantly women (53% vs. 32%; P<0.0001), had a higher logistic EuroSCORE (3.26 vs. 2.43; P<0.001), more preoperative atrial fibrillation (20% vs. 13%; P=0.03), and had a lower reopening rate for bleeding (2.1% vs. 6.7%; P=0.04). Compared to Group B1, Group A1 had shorter cross-clamp (mean 40 min vs. 57 min; P≤0.0001) and bypass times (mean 63 min vs. mean 80 min; P=0.02), and they bled less postoperatively (mean 295 ml vs. mean 393 ml; P=0.002). The mean gradient across Perceval valve was 12.5 mmHg while its effective orifice area was 1.5 cm2. CONCLUSION: In our retrospective study of 763 patients, sutureless valve group patients are older, mostly women, more symptomatic preoperatively, and have higher logistic EuroSCORE. They have shorter cross-clamp and bypass times, less postoperative bleeding, and reduced incidence of reopening. Further studies are needed to evaluate the clinical benefits in short, mid, and long-terms.

Thrombocytopenia After Aortic Valve Replacement: Comparison Between Sutureless Perceval S Valve and Perimount Magna Ease Bioprosthesis.

INTRODUCTION: The incidence of postoperative thrombocytopenia after aortic valve replacement (AVR) with the Perceval S Sutureless bioprosthesis remains unclear. The aim of this study was to report thrombocytopenia associated with the use of sutureless AVR. METHODS: The data was collected retrospectively for patients who had isolated AVR with sutureless Perceval S valve (Group A: 72 patients) and was compared with patients who underwent isolated sutured AVR with Perimount Magna Ease Bioprosthesis (Group B: 101 patients) in our institution between June 2014 and January 2017. RESULTS: Cardiopulmonary bypass and cross-clamp time were significantly shorter in group A. Maximum drop in platelet count was 58% mean (day 2.3) in group A versus 44% mean (day 1.7) in group B (P=0.0001). Absolute platelet count on postoperative day 1-6 in group A was significantly less than in group B (P≤0.05). Platelet count recovered to preoperative value in 44% patients in group B versus only in 26% patients in group A at discharge (P=0.018). Moderate thrombocytopenia occurs more often in group A (41% vs. 26%) (P=0.008) while severe thrombocytopenia (<50 x 109) was observed in 6% in group A but never in group B. Platelets (P=0.007) and packed red blood cells (P=0.009) transfusion was significantly higher in the group A. CONCLUSION: The implantation of sutureless Perceval aortic valves was associated with a significant drop in platelet count postoperatively with slow recovery and higher platelets and packed red blood cells transfusion requirements. A prospective randomised trial is needed to confirm our findings.

Early Clinical Results of Perceval Sutureless Aortic Valve in 139 Patients: Freeman Experience.

OBJECTIVE: The aim of this retrospective study is to evaluate the safety and performance of the Perceval sutureless valve in patients undergoing aortic valve replacement. We report the 30-day clinical outcomes of 139 patients. METHODS: From January 2014 to December 2016, 139 patients underwent sutureless aortic valve replacement. Their operation notes, National Adult Cardiac Surgery Database and perioperative transoesophageal echocardiography findings were studied retrospectively. RESULTS: Ninety-two patients underwent isolated aortic valve replacement (group A) with Perceval valve and 47 patients had combined procedures of aortic valve replacement and coronary artery bypass grafting (group B). The patients received a size S (n=23), M (n=39), L (n=42) or XL (n=35) prosthesis. Perceval valve was successfully implanted in 135 (97.1%) patients. Mean cross-clamping time and bypass time were 40 and 63 minutes for isolated cases, while 68 and 107 minutes for combined cases. Three (2.1%) patients died within 30 days. Four patients suffered stroke and 5 patients went into acute renal failure. Median intensive care unit and hospital stay was 2 and 8.5, respectively. Four valves were explanted due to significant paravalvular leak after surgery. Five patients had permanent pacemaker as a result of complete heart block and mean postoperative drainage was 295 mL for isolated case and 457 mL for combined cases. The mean gradient across Perceval valve was 12.5 mmHg while its effective orifice area was 1.5 cm2. CONCLUSION: Early postoperative results showed that Perceval valve is safe. Further follow up is needed to evaluate the long-term outcome with this bioprosthesis.

Malrotation of midgut in adults, an unsuspected and neglected condition--An analysis of 64 consensus confirmed cases.

INTRODUCTION: Malrotation of midgut is considered to be a condition of childhood. This study evaluated malrotation in adults with recurrent abdominal pain (RAP). METHODS: Sixty-four consensus-confirmed cases of intestinal malrotation were reviewed. The diagnosis was based on radiological criteria, and the consensus was arrived at by at least three of the five authors in any individual case. RESULTS: Abnormal duodenojejunal junction (DJJ) was a consensus finding in 64 cases referred for RAP. Most were in their fourth decade of life, and 12 were beyond 60 years. Besides RAP, intolerance to food was the next common symptom. Acute intestinal obstruction was seen in 16. Forty-two of 64 patients consented for surgery. Ladd's procedure was the commonest. All patients who underwent surgery were symptom free except for two, of which, one had liver cyst and the other had hernia. Of those who refused surgery (22), all had continued symptoms and 10 patients took alternative therapies. On follow up of initially unwilling patients (for surgery) with abnormal DJJ, only eight consented for surgery; three underwent open Ladd's procedure, and one had laparoscopic Ladd's done. CONCLUSION: Malrotation is not uncommon as a cause of RAP in adults.

Haemoptysis in an intravenous drug user: injection needle impacted in the left main bronchus.

We report a case of a 35-year-old man who presented with 4-week history of haemoptysis, with a history of intravenous drug use. There was no other significant medical or surgical history and no recollection of any foreign body aspiration. Chest X-ray and CT scan showed 40 mm long needle in left main bronchus, partly lying outside the bronchus into the mediastinum. Flexible and rigid bronchoscopes proved to be unsuccessful in retrieving the needle. We proceeded with left posterolateral thoracotomy and the left main bronchus was explored to take out this 21-gauge (green) injection needle. The distal half of the needle with the sharp end was lying in the mediastinum piercing through the bronchial wall. Surgery was uneventful with good postoperative recovery and the patient was discharged 4 days later.

Early clinical results of perceval sutureless aortic valve in 139 patients: freeman experience

Abstract Objective: The aim of this retrospective study is to evaluate the safety and performance of the Perceval sutureless valve in patients undergoing aortic valve replacement.
