Abstract A new 3D printable resin formulation is developed and optimized from commercially available thiol (pentaerythritol tetrakis(3‐mercaptopropionate); PETMP) and alkyne (3‐butyn‐1‐ol; BA) monomers. Printed objects are characterized by Fourier‐transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). The extraction efficiency of the printed thiol‐yne device is then investigated using a model dye – malachite green (MG). The results displayed excellent dye removal efficiency with > 95% MG removed within 5 min. The 3D‐printed devices are reusable and show 100% removal over six cycles after washing with deionized water and methanol. The presence of surface hydroxyl groups derived from the BA monomer is shown to enhance dye adsorption in comparison to control materials. The printing procedure and resin formulation are robust and consistent when devices from different resin batches are compared for MG dye removal. The thiol‐yne 3D printed devices demonstrated excellent dye removal (> 99%) from water samples collected from a tap and a nearby river source. The successful development of this resin provides a new thiol‐yne‐based resin system for stereolithography (SLA) 3D printing for the removal of organic dyes from wastewater and presents a potential for broad applications in water treatment.

Abstract Objective Peritonitis is the most common life threatening surgical emergency, which requires urgent surgical intervention and is a significant cause of morbidity and mortality. The objective of this study was to highlight the frequency of secondary peritonitis and to analyze the site and causes of perforation, in our tertiary care setup. Methods A retrospective analysis of 311 patients of secondary peritonitis was done from July 2008 to June 2010 at Liaquat University Hospital Jamshoro, Hyderabad, Sindh, Pakistan. All cases found to have peritonitis as a result of perforation of any part of gastrointestinal tract at the time of surgery were included in the study. All cases with either primary peritonitis or that due to anastomotic dehiscence were excluded. Results A total of 311 patients were studied. Most of the patients were males (77%) and (89%) were in the third and fourth decades of life. Majority of the patients presented with pain (97%) associated with bowel symptoms. Most common site of perforation was small bowel (ileal 59%, jujenal 2%). In this series, most common risk factor of perforation was typhoid (43%). Ileostomy was the most commonly performed procedure. Overall morbidity was 48.5% and mortality was 17%. Conclusion Considering the relatively higher rate of typhoid perforation quoted in this study, it is vital that typhoid fever ought to be eliminated by improved sanitation and immunizing programmes, otherwise surgeons will be confronted with its complications.

Background: Throughout history, regardless of their culture, women have tried to avoid unwanted pregnancies by using more or less reliable method however most cultures have certain myths based upon rumors without any medical or scientific proof, which are often linked to taboos. Material and Methods: This was an observational study which was carried out over the duration of 4 weeks i.e. from 30th September 2011 to 28th October 2011 at Outpatient department of Civil Hospital Hyderabad. Total numbers of participants were 280. All the married women of reproductive age group were included in the study and those who are single and who are already practicing oral contraceptive pills were excluded from the study. Results: The majority of women were between the age group of 15-29 years(50.7%) while 49.2% of the sample was between the age group of 30-45 years. Among 280 women, 176(62.8%) were educated and 104(37.1%) were illiterate. Majority of educated women (103) got secondary education. 46 women received primary education while only 27 women were graduated. 144(81%) educated women and 100(96%) uneducated women believes in misperceptions about OCPs.160(57.1%) women belong to urban while 120(42.8%) women belong to rural areas. Conclusion: We should educate and empower women to make informed choices about their reproductive health, and reaffirm our shared values: healthy women, healthy families, and a healthy environment.
