    Introduction One uncommon cause of right iliac fossa pain is toothpick ingestion leading to intestinal perforation. It is a difficult diagnosis due to its nonspecific clinical presentation and investigation findings. In spite of this, individuals who have a high risk of morbidity and death may have severe consequences from toothpick intake, hence it is crucial to diagnose the condition accurately.  Case report In the study, a young man with right iliac fossa discomfort—first thought to be appendicitis—had his ileocaecal junction perforated by a toothpick, which was discovered to be the source of the pain during surgery.  Conclusion When a patient presents with an acute abdomen, clinicians need to be aware that a foreign body ingestion may have been the cause. It is also necessary to educate the general people about the dangers of using toothpick

    The box-girder bridge has become very popular lately due to its serviceability, stability, and structural efficiency. The study of such a bridge requires analytical, experimental, or numerical methods. The structural behavior of the box-girder bridge is very complex and is quite cumbersome to be investigated by conventional methods. This paper presents a modelling process for the analysis of simply supported reinforced concrete (RC) box-girder bridges (straight, skew, curve, and skew-curved) using the finite element method under Indian loading conditions. This modelling process is developed on the basis of the Codal provisions of Indian Road Congress (IRC) 6:2017 and IRC 21:2000, and its implementation is quite simple as it avoids the cumbersome calculations and requires less time. Different values of the span, span-depth ratio, and the number of cells are considered to suit the requirements, and limiting criteria for stresses and deflection are checked. The static and free vibration analyses are carried out, and the results are compared to control the applicability of the proposed modelling process. The present modelling process is applied to analyse the RC box-girder bridges up to 50 m spans, and no erection procedure is included. However, one may follow the proposed modelling procedure for any box-girder bridge for its analysis

    Dynamic pressure on lock gate structure coupled with fluid

    The effect of fluid on the dynamic pressure distribution of a rectangular lock gate structure subjected to external harmonic ground acceleration is studied. The fluid is assumed to be inviscid and incompressible, having an irrotational flow. Pressure for fluid domain and displacement for lock gate are considered as nodal variables in the finite element formulation. The interaction of coupled problem is maintained by transferring acceleration of the lock gate to fluid and pressure of the fluid to lock gate. Mindlin’s plate theory is used to formulate the lock gate. The Laplace equation is solved using Fourier half range cosine series expansion to truncate the far boundary nearer to the lock gate. The time dependent forced vibration equations are solved by using Newmark-beta time integration method

    INITIAL EXPERIENCE AND OUTCOMES OF SINGLE-PORT LAPAROSCOPIC TRANSABDOMINAL PREPERITONEAL REPAIR FOR INGUINAL HERNIAS, BIHAR, INDIA: A CLINICAL STUDY.

    Introduction Inguinal hernia repair is the most common surgery worldwide. Laparoscopic inguinal hernia repair has many advantages over open treatment. Single-incision laparoscopic surgery (SILS) reduces the invasiveness of laparoscopy. This innovative approach has garnered considerable success and has been effectively executed by numerous skilled surgeons.  Methods The present study was conducted over a duration of twelve months, within the Department of General Surgery in a tertiary care centre. This study was conducted on a cohort of 40 patients who presented with uncomplicated inguinal hernia. Among this group, 20 patients underwent single port laparoscopic transabdominal preperitoneal (TAPP) repair, while the remaining 20 patients underwent conventional TAPP repair.  Results The average age, weight, and height were 43.45 years, 58.46 kilograms, and 156.1 centimeters, respectively. These measurements were found to be nearly identical for both conventional TAPP procedures, indicating no statistically significant differences. In the present study, a total of 24 participants (51%) were diagnosed with indirect inguinal hernia, while 22 participants (47%) were diagnosed with direct inguinal hernia. Notably, the observed disparity between the two groups was found to be statistically insignificant. There was a notable increase in postoperative complications observed in patients who underwent the conventional transabdominal preperitoneal (TAPP) procedure. The duration of hospitalization following single port TAPP surgery was observed to be significantly shorter compared to conventional TAPP surgery.  Conclusion  Therefore, in comparison to the conventional technique, single port TAPP surgery demonstrates a reduced duration of the procedure and administration of general anesthesia. Additionally, it presents a decreased incidence of postoperative complications, a shorter hospitalization period, and an expedited recovery process.  Recommendations The study recommends single-port laparoscopic transabdominal preperitoneal (TAPP) repair for simple inguinal hernias. It decreases process time, postoperative issues, hospitalization, and recovery time compared to normal TAPP repair. Surgeons considering inguinal hernia surgery should consider these benefits

    Metal foams and alloy foams are a novel class of engineering materials and have numerous applications because of their properties such as high energy absorption, light weight and high compressive strength. In the present study, the methodology adopted to develop a Ni-Cr alloy foam is discussed. Polyurethane (PU) foam of 40PPI (parts per inch) pore density was used as the precursor and coating techniques such as electroless nickel plating (ELN), ultrasonic-assisted electroplating of nickel (UAEPN), and pack cementation or chromizing were used to develop the Ni-Cr alloy foam. The surface morphology, strut thickness and minimum weight gain after each coating stage were evaluated. It was observed from the results that the adopted coating techniques did not damage the original ligament cross-section of the PU precursor. The minimum weight gain and the coating thickness after the UAEPN process were observed to be 42 g and 40–60 μm, respectively. The properties such as porosity percentage, permeability and compressive strength were evaluated. Finally, the pressure drop through the developed foam was estimated and verified to determine whether the developed foam can be used for filtering applications.Filipe Fernandes acknowledges the CEMMPRE (UIDB/00285/2020) and ARISE (LA/P/0112/2020) projects, sponsored by national funds through the FCT—Fundação para a Ciência e a Tecnologia

    Congenital birth defects are major cause of poor health among infants affecting their survivability. Although such anomalies of the eyes are uncommon, the impact they have on the quality of life are more than significant. This study aimed to describe the clinical profile of congenital ocular anomalies with various epidemiological parameters in a tertiary health care center in western Orissa. The study screened 3674 patients, in the age group of 0 – 14 years, who were delivered or attended the out-patient Department V.S.S. Medical College, Burla, Odisha and included 151 eyes of 99 cases of various types of congenital anomalies. Detailed history and other necessary data were collected by trained ophthalmologists and descriptive analyses performed. The incidence of congenital ocular anomalies was found to be 2.69%. Nasolacrimal duct anomalies (47 eyes) were the most frequently occurring congenital ocular anomaly (31.1%); followed by congenital cataract (41 cases; 27.3%) and coloboma eye (18 cases; 11.9%).There was a slight male preponderance, constituting 56.57% of the total cases. Majority of the patients were less than 5 years old (68 %) and the incidence of congenital ocular anomalies to be highest (68.69%) in the age group of 0 – 5 years
