Early Outcomes of Laparoscopic Transabdominal Preperitoneal (TAPP) Repair.

Background Inguinal hernia repair is one of the commonest general surgical procedures performed all over the world. The introduction of synthetic mesh and laparoscopic repair has revolutionized inguinal hernia surgery in the recent past. Laparoscopic transabdominal preperitoneal (TAPP) repair is now considered a well-established procedure with minimal complications and short hospital stay and less recurrence.

Graphene Modified Polyaniline-Hydrogel Based Stretchable Supercapacitor with High Capacitance and Excellent Stretching Stability.

Conjugated polymers have been widely adopted as active materials in hydrogel-based stretchable supercapacitors, but the relatively low conductivity and poor structural stability limit their applications. Herein, highly conductive graphene was incorporated as a substrate to anchor polyaniline (PANI) in a hydrogel-based stretchable electrode. Graphene not only provided an effective conducting network in the electrode, but also stabilized PANI during repeating charge-discharge processes due to strong π-π interaction between graphene and PANI.

Surgical smoke; an occupational hazard.

Surgical smoke is part of the environment during operative and invasive procedures. Electric diathermy is a very important tool for a surgeon and is used in every surgical treatment nowadays. It assists the surgeon to dissect the tissue or enables securing haemostasis in lesser time and with larger delicacy.

Nb-Doped MXene With Enhanced Energy Storage Capacity and Stability.

MXenes present unique features as materials for energy storage; however, limited interlayer distance, and structural stability with ongoing cycling limit their applications. Here, we have developed a unique method involving incorporating Nb atoms into MXene (TiC) to enhance its ability to achieve higher ionic storage and longer stability. Computational analysis using density functional theory was performed that explained the material structure, electronic structure, band structure, and density of states in atomistic detail.

Lecithin-coated gold nanoflowers (GNFs) for CT scan imaging applications and biochemical parameters; in vitro and in vivo studies.

We report a novel strategy for the fabrication of lecithin-coated gold nanoflowers (GNFs) via single-step design for CT imaging application. Field-emission electron microscope confirmed flowers like morphology of the as-synthesized nanostructures. Furthermore, these show absorption peak in near-infrared (NIR) region at λ 690 nm Different concentrations of GNFs are tested as a contrast agent in CT scans at tube voltage 135 kV and tube current 350 mA.

One stage emergency resection and primary anastomosis for sigmoid volvulus.

Objective: To evaluate the safety of single stage resection and primary anastomosis (RPA) in cases of viable sigmoid volvulus, in terms of anastomotic healing and complications.

Study Design: Observational study.

Place And Duration Of Study: Surgical Unit, Hayatabad Medical Complex (HMC), Postgraduate Medical Institute, Peshawar, from November 2006 to October 2008.

Fine needle aspiration cytology (FNAC) and neck swellings in the surgical outpatient.

Background: Fine Needle Aspiration Cytology (FNAC) is a simple, quick and inexpensive method that is used to sample superficial masses like those found in the neck and is usually performed in the outpatient clinic. It causes minimal trauma to the patient and carries virtually no risk of complications. Masses located within the region of the head and neck, including salivary gland and thyroid gland lesions can be readily diagnosed using this technique.
