Epiploic Appendagitis Unveiled: A Case of Misleading Abdominal Pain With Omental Fat Necrosis.

Epiploic appendagitis is a benign inflammatory condition of the epiploic appendages, small fat-filled structures attached to the colon. Misdiagnosed frequently as more serious conditions like appendicitis or diverticulitis, it usually resolves with minimal treatment. This case report aims to emphasize the importance of recognizing epiploic appendagitis in differential diagnoses, highlighting the role of accurate imaging and surgical intervention in managing unusual presentations. We report a case involving a 27-year-old male who presented with acute, severe pain in the left iliac fossa. Initial assessments showed stable vital signs and negative virology screenings. Ultrasound imaging did not reveal any abnormalities in the abdominal organs but noted multiple gas-filled bowel loops and a 48 x 22 mm collection in the left iliac region. A CT scan with IV contrast further identified a 35 x 26 mm area of fat stranding in the left iliac fossa, indicative of epiploic appendagitis, and a 1 cm area of omental fat necrosis near the hepatic flexure. Persistent symptoms led to a diagnostic laparoscopy, which confirmed and treated gangrenous appendices epiploica. The patient's postoperative recovery was uneventful, highlighting the effectiveness of surgical management. This case underscores the necessity for heightened awareness and diagnostic precision when encountering patients with acute abdominal pain that does not match common ailments. Early and accurate imaging, followed by timely surgical intervention if needed, can significantly improve outcomes by preventing complications from misdiagnosis or delayed treatment.

Evaluating Postoperative Prognosis: A Single Surgeon's Experience With Total Mesorectal Excision in Middle and Lower Rectal Cancer Cases in Iraq.

INTRODUCTION: Surgical intervention for rectal cancer is widely recognized for its potential to significantly impact quality of life, chiefly due to the high probability of permanent colostomy and the associated postoperative complications. OBJECTIVE: This study aimed to evaluate the short-term outcomes and morbidity associated with total mesorectal excision for middle and lower rectal cancer within an Iraqi cohort, in a prospective setting. METHODS: This study prospectively collected and analyzed data from 89 patients who underwent a standardized radical rectal resection, with a follow-up period extending to one month post-surgery. RESULTS: The mean age of patients was 54.4 ± 12.9 years, with a gender distribution of 46 males and 43 females. A total of 33 patients presented with preoperative comorbidities, which heightened the risk of adverse short-term outcomes by a factor of 7.51. The most prevalent comorbidities were hypertension and diabetes mellitus, affecting 22 and 20 patients, respectively. Patients aged 60 years and above were at a 3.97 times greater risk of developing complications. The overall complication rate was 21.35%, with wound infections (9.0%) and cardiovascular events (3.4%) being the most common. Mortality during the follow-up was 1.1%. CONCLUSION: The findings indicate that increased age and the presence of comorbidities are significant risk factors for morbidity and mortality post-surgery. Neoadjuvant chemoradiotherapy or radiotherapy was shown to reduce morbidity and mortality rates while improving survival. The morbidity and mortality rates observed in this study concur with existing literature.

Comparative Analysis of Strength of Differently Activated Denture Base Materials Including Recent Acetal Resin-Based Biodentaplast.

AIM AND OBJECTIVES: The aim of this study is to comparatively analyse the compressive and tensile strength of different types of record base materials made of different materials and processing techniques. MATERIALS AND METHODOLOGY: The compressive and tensile strength of 4 types of injection moulded materials were compared with a control of conventional compression moulded material. Twenty test specimens (10 tensile and 10 compressive) were fabricated from each material. A test was done using the Instron 3382 (Norwood, MA, USA) universal testing machine. RESULTS: Compressive and tensile test values showed significant differences between the record base resin groups tested for both compressive and tensile strength tests (p=0.00). The mean tensile strength value was greatest for Group V (66.0 MPa) and lowest for Group III (41.9MPa) and the mean compressive strength value was greatest for Group I (74.5 MPa) followed by Group V (70.2 MPa) and lowest for Group III (10.8 MPa). CONCLUSION: Injection moulded acetal resin showed the highest tensile strength value; it was comparable to that of conventional compression moulded polymethyl methacrylate (PMMA). Compression moulding is reported to have the highest compressive strength values followed by injection moulded acetal resin material. Injection moulded acetal resin material attributed to its advantages and superior strength value, can be used as a material of choice in various clinical scenarios.

Esthetic Rehabilitation of a Young Patient With Immediately Loaded Single-Piece Basal Implants Following a Trauma Involving the Anterior Maxilla: Case Report With Five-Year Follow-Up.

Traumatic injuries to the anterior maxilla usually lead to loss of teeth by means of avulsion or extraction due to fracture. Rehabilitation of such a clinical scenario is complex as it involves various anatomic and esthetic challenges. Single-piece basal implants have been widely used in the rehabilitation of resorbed ridges because they gain adequate anchorage from the basal cortical bone, allowing immediate temporization or loading. However, the use of basal implants in the anterior esthetic zone is not much documented. This case report with a five-year follow-up period describes the rehabilitation of lost teeth in the anterior esthetic zone of the anterior maxilla caused due to trauma following a train accident using single-piece axial basal implants with immediate temporization.

Assessment of Prevalent Gingival Shades in the South Indian Population: An Observational Study.

INTRODUCTION: Gingival shade matching, often overlooked, plays an integral role in designing prostheses for patients with high smile lines, gingival defects, and cases where the acrylic flange of removable dentures extends into the aesthetic zone. The purpose of this study was to find the most prevalent gingival shade in a sample of the South Indian population. MATERIALS AND METHODS:  A total of 110 participants were included in the study based on the inclusion and exclusion criteria. The standard daylight method of shade matching was used for this study. The participants were seated in a dental chair in the vertical position with their heads supported, their mouths open, and cheek retractors in place. The study area, gingiva, and vestibular region in relation to maxillary and mandibular right central incisors were dried with a three-way syringe, 15cm away, for 3 seconds before shade matching for 5 seconds at each reference point with an Ivoclar Vivadent IPS Dsign shade guide. CONCLUSION: The most prevalent shade in the marginal and vestibular regions of the gingiva of the South Indian population was found to be GM2 shade, while the most prevalent shade of the attached gingiva was found to be G2 shade. A good percentage of the attached gingival shade was not matched with the tabs available in this shade guide.

Pancreatic insulinoma misdiagnosed as atrial fibrillation: A case report from Iraq.

RATIONALE: Pancreatic insulinomas are the most frequent pancreatic endocrine neoplasms. They are insulin-secreting pancreatic tumors that induce extreme, recurrent, and near-fatal hypoglycemia. Insulinomas affect 1 to 4 individuals in a million of the general population and account for about 1% to 2% of all pancreatic tumors. PATIENT CONCERNS: Recurrent episodes of sweating, tremor, weakness, confusion, palpitation, blurred vision, and fainting for 2 months and was misdiagnosed as having atrial fibrillation. DIAGNOSIS: He was misdiagnosed as having atrial fibrillation to highlight the importance of atrial fibrillation as unusual mimicker of insulinoma and to encourage clinicians about the importance of early and appropriate management in such cases. INTERVENTIONS: Endoscopic ultrasound for the pancreatic parenchyma was done, and it showed a hypoechoic homogenous mass located at the pancreatic head measuring 12 mm × 15 mm with no local vascular involvement, blue in elastography, hypervascular with Doppler study, and a normal pancreatic duct diameter. OUTCOMES: His condition was stable, and he was discharged home 2 days later. CONCLUSION: The diagnosis of insulinoma is usually difficult and late due to the extremely low incidence of the disease and the similarity of its clinical presentation to numerous other conditions, the most reported is epilepsy.

Performance Assessment of First-Generation AntiSARS-CoV-2 Serological Assays

The clinical and epidemiological use of SARS-CoV-2 antibody assays is under debate with urgent need to validate and verify the performance of SARS-CoV-2 serologic assays. We aim to assess the clinical and analytical performance of three commercial serological assays of SARS-CoV-2, comparing three anti-SARS-CoV-2-IgG ELISA and identifying the seroconversion and seroprevalence in our population. A cross sectional study conducted from April 2020 to July 2020 at National Institute of Blood disease and Bone Marrow Transplantation Karachi, Pakistan with sample size of 404, enrolled consecutively. Participants were categorized into four groups namely convalescent plasmadonors (CPDs n=239), health care professionals (HCPs n=44), healthy blood donors (HBDs n=70) and from community (n=51). We evaluated the performance of Elecsys anti-SARS-CoV-2 electrochemiluminescence (ECLIA) assay on Cobas-e411 by Roche, three qualitative anti-SARS-CoV-2-IgG enzyme linked imunosorbant assay (ELISA) by (Generic assays, Euroimmun & Omega diagnostics), one quantitative ELISA assay by AESKU Diagnostics and two immune chromatography(ICT) kits namely InstaTest by CORTEZ and TEST IT by TURKLAB. From total 404 subjects, 322 (83.5%) were males. Mean age was 36.79{+/-}11.95 years. Among 239 in CPDs group, 202(84.5%) showed positive antibodies by ECLIA. The qualitative anti-SARS-CoV-2 IgG ELISA was positive in 174 (72.8%) and quantitative IgG in 180(75.3%) with mean titer of 56.7 {+/-}39.7 U/ml. Sensitivity and specificity of ECLIA were 97.44& 99%, ELISA by Generic assays were 67.85% and 89.9%; Euroimmun had 90.38% and 94.9%; Omega Diagnostics 96.4% and 95% and the AESKULISA 93.75% and 100% respectively. Seroconversion was found to be 53.8% and 77.77% within 7 -8 days and 12 to 14 days post onset of symptoms respectively. ICT had more specificity but less sensitivity. Seroprevalence was found to be 84.5%, 40.9% and 21.4% in CPDs, HCPs and HBDs respectively. The Roche ECLIA, qualitative ELISA by Omega Diagnostics & Euroimmun showed higher sensitivity as well as higher specificity. Quantitative ELISA has higher specificity and relatively high sensitivity. Significant numbers of COVID patients do not have detectable antibodies by all assays.

Optical properties of polyvinyl alcohol membrane with n-HAp for bio-medical applications

Composite membrane as a flexible materials have found diverse applications in industrial and biomedical simultaneously, the recent studies have shown intrinsic improvement for membrane properties by inclusion of nanoparticles as a fillers with high portion ratio in inorganic polymers, the combination between two parts polymer and filler is as a result of collection the advantage of two component systems parts together. In this work, samples of polyvinyl alcohol (PVA)-nanoHaydroxyapatite (nHAp) composites were prepared by using casting method. The effects of addition of (nHAp) with different concentration on the optical properties of (PVA- nHAp) composite membrane have been studied by using wavelength range (220-820) nm. The absorption spectra, transmittance spectra, absorption coefficient, energy gap, refractive index, optical conductivity and extinction coefficient have been determined. The results show that the optical constants change with the increase of nHPA concentrations.

Primary atypical teratoid rhabdoid tumor in the adult spine.

BACKGROUND: Atypical teratoid/rhabdoid tumor (ATRT) is a highly aggressive tumor of the central nervous system (WHO grade IV), which is most frequently found intracranially in young children and infants. Only three prior cases of primary ATRT involving the adult spine were found following a literature review, and the average survival for these patients was only 20 postoperative months. CASE DESCRIPTION: A 43 year-old female presented with an acute exacerbation of chronic neck pain. While awaiting magnetic resonance (MR) studies of the cervical spine, she was found pulseless in her room. Although cardiopulmonary resuscitation was successful, she was found to be quadriplegic. The subsequent cervical MR imaging revealed a C1-3 intradural, extramedullary ventrolateral mass, markedly compressing the upper cervical spinal cord. Following successful surgical resection of the lesion, which proved pathologically to be an ATRT, she was treated with a full course of fractionated radiation therapy. Over the successive 6-month period, her neurological examination continued to improve to 4-/5 functional strength in her upper extremities, however, remained with 2/5 nonfunctional strength in her legs. CONCLUSIONS: ATRT involving the adult spine are rare and may often be misdiagnosed. This study points out that aggressive surgery followed by radiation therapy may improve outcome.

Post-Traumatic brain injury (TBI) presenting with Guillain-Barré syndrome and elevated anti-ganglioside antibodies: a case report and review of the literature.

Guillain-Barré Syndrome (GBS) is a demyelinating polyneuropathy resulting in sensory, motor and autonomic symptoms. The severity of the disease can range from mild to severe but it is classically described as an ascending demyelinating process. Initially thought to be the sequelae of a bacterial or viral infection, the clinical symptoms of post-infective GBS can present up to 4 weeks after sentinel injury. A rarely defined post-surgical GBS has been since described after major cranial, cardiothoracic and gastro-intestinal surgery. Post traumatic GBS is an even more unusual presentation with very few cases reported in contemporary academic literature. We present a case of GBS presenting two weeks after non-operative traumatic brain injury (TBI) and a review of the literature.

Paramedian approach for transforaminal lumbar interbody fusion with unilateral pedicle screw fixation. Technical note and preliminary report on 47 cases.

Lumbar fusion is a commonly performed procedure for a variety of pathological conditions, and it is frequently used in the treatment of degenerative lumbar instability that is refractory to medical management. Pedicle screws and interbody devices have been used for internal fixation to promote arthrodesis, prevent nonunion, and facilitate early mobilization. Recently, attempts have been made to reduce the morbidity associated with lumbar fusion by using a variety of minimally invasive techniques. Many minimally invasive lumbar fusion procedures require specialized retractors, implants, image guidance systems, or insertion instruments. Other minimally invasive techniques are primarily applied to an ideal patient population (thin, healthy, and with no previous surgery). The authors describe their experience with a paramedian approach for minimally invasive transforaminal lumbar interbody fusion (TLIF) with unilateral pedicle screw (PS) fixation. This procedure requires only standard implants, instruments, and retractors, with direct visualization for all aspects of the procedure. The authors describe encouraging early results in a challenging patient population in which there was a high incidence of obesity, medical comorbidities, and previous surgery at the same level. The paramedian approach for TLIF performed using unilateral lumbar PSs has yielded successful outcomes in this series of 47 patients, and further study of this technique may help define its role as a minimally invasive procedure for spinal fusion.

Nitric oxide diffusing capacity and alveolar microvascular recruitment in sarcoidosis.

We measured diffusing capacities for carbon monoxide (DLCO) and nitric oxide, lung volume, and cardiac output by a rebreathing technique at two alveolar O2 tensions (PAO2) at rest and exercise. Membrane diffusing capacity for CO (DMCO) and VC were estimated from DLCO by the Roughton-Forster (RF) method and also from simultaneous lung diffusing capacity for NO and DLCO measured at one O2 tension (modified RF method). Estimates by these methods agreed closely in normal subjects (Tamhane et al., Chest 2001;120:1850-1856). Using these methods, we studied patients with stages II-III pulmonary sarcoidosis to determine (1) whether the modified RF method accurately estimates DMCO and VC in parenchymal disease and (2) whether sarcoidosis alters recruitment of diffusing capacity with respect to cardiac output. In patients, DMCO and VC estimated by the two methods agreed closely. DMCO was disproportionately reduced relative to VC at any given cardiac output, and the slope of the relationship between DLCO and cardiac output was moderately, though significantly, below normal. We conclude that in sarcoidosis (1) the modified RF method provides comparable estimates of DMCO and VC as the standard RF method and (2) the limitation to diffusive gas transport resides primarily in the membrane barrier, although recruitment of microvascular reserves is also modestly impaired.
