The application of monolithic material sorption extraction, specifically MonoTrapTM, to the extraction of organic gunshot residue (OGSR) compounds from unburnt propellant powders is described. Four different MonoTraps were assessed for their capability to extract OGSR compounds from two different ammunition types. Extracts were analysed using gas chromatography-mass spectrometry. Results indicated that the carbon disc was suitable for the extraction of OGSR compounds from unburnt propellant powders. Quantities for major compounds were comparable to methanol extractions. The method was successfully used to detect a wide range of OGSR compounds, including nitrotoluenes, nitroglycerin, diphenylamines and centralites and is expected to be applicable to a wide range of ammunition types.

Potter syndrome (PS) is a term used to describe a typical physical appearance, which is the result of dramatically decreased amniotic fluid volume secondary to renal diseases such as bilateral renal agenesis (BRA). Other causes are abstraction of the urinary tract, autosomal recessive polycystic kidney disease (ARPKD), autosomal dominant polycystic kidney disease (ADPKD) and renal hypoplasia. In 1946, Dr Edith Potter characterized this prenatal renal failure/renal agenesis and the resulting physical characteristics of the fetus/infant that result from oligohydramnios as well as the complete absence of amniotic fluid (anhydramnios). Oligohydramnios and anhydramnios can also be due to the result of leakage of amniotic fluid from rupturing of the amniotic membranes. The case reported below, concerns of stillborn boy with potter syndrome.

Introduction: Fractures of both the anterior and posterior pelvic ring are common injuries in polytrauma and the elderly that extend beyond those of simple low-impact trauma. While conventional X-rays predominantly show the ventral aspect of the injury, computed tomography often detect additional fractures of the sacrum. A large number of these fractures are B-injuries by AO, mainly compression fractures at an advanced age. In addition, the prevalence of pelvic insufficiency fractures caused by osteoporosis rather than subsequent to an obvious trauma is increasing, with such an injury often associated with pain that impairs mobilization. The standard sacroiliac screw fixation is often characterized by loosening and thus failure of the osteosynthesis especially in osteoporotic bone of elderly patients. Method: A new alternative surgical minimal invasive technique, the “iliosacral bridging”, stabilizes the fractures of the sacrum with an internal fixation from S1 pedicle of the uninjured side to the ilium on the affected side. The combination of this internal fixation with the standard single sacroiliac screw on the injured side allows an immediate full weight bearing and pain free mobilization. We present a case series of 8 patients. Results: The clinical and radiological analysis analogous to the pelvic-outcome-score brought forward that 2 patients showed an excellent and 2 patient a good result. The other 4 patients achieved sufficient results. Conclusions: The “iliosacral bridging” we have introduced in the present study provides evidence of an expected increased stability of the pelvis after B-injuries

Taphonomic study was first time conducted in Kuala Lumpur, capital city of Malaysia. In this research model, male Oryctolagus cunicullus weighed 1.8-2.6 kg each were killed by Dolethal intravenously at the ear region. In Phase 1 study, eight subjects were wrapped in a sack and cemented within a container to be compared with the other four controls at each location labelled A (ground) and B (manmade freshwater pond). Phase 2 involved duplicating set of 15 cemented samples comparable to 1 control made up to total of 32 subjects which were all put into a compact polytank containing freshwater to simulate a case study. Taphonomic changes were observed and scored using TBS system incorporating of fresh stage, early decomposition stage, advanced decomposition stage and skeletonisation stage. The ambient temperature of surroundings with 28.81C±4.21°C and 29.21°C±4.57°C (mean±S.D.) while relative humidity of air with 74.49 %±14.61% and 79.15%±16.32% (mean±S.D.) were recorded for Phase 1 and Phase 2 study respectively. Time taken for ground control exposed and wrapped carcasses to reach first sign of skeletonised stage were four days and five days respectively. Whilst freshwater controls reached initial skeletonised stage within one week for exposed carcass and two weeks for wrapped carcass. Within the control and cemented sample carcasses, TBS scores increased from initial stages of decomposition and become plateau after advanced decomposition. The cementing factor have superseded the wrapping factor due to its stronger physical barrier effect to slow down the decomposition more than half compared to controls based on Multiple way ANOVA test. Phase 2 study has demonstrated more accurately on the decomposition rate of the cemented samples. It showed that wrapping and cementing factors have delayed the decomposition process of the rabbit carcasses about 4 times to reach the initial stage of skeletonisation compared to the control carcasses. There was absence of insect activity within the cemented samples, hence the microorganism activity would be the only contributor to the decaying process within the cemented samples at slower rate comparing to the exposed or wrapped controls.

Background: The burden of depression as a mental disorder has continued to increase and constituting an enormous public health concern among all age groups. A number of socio-demographic, and other factors including a stressful and rigorous academic programme or curriculum such as the one run in most medical schools could contribute to the occurrence of depression among medical students. AIM: To determine the socio-demographic and other factors associated with depression among medical students in the University of Port Harcourt. Methodology: This study was a descriptive cross-sectional study. Appropriate sample size was calculated and the stratified random sampling method was used to select the subjects. A well-structured open ended self-administered socio-demographic questionnaire was administered to the students. The Zung Self-Rated Depression Scale was used to assess the depression status of each respondent. The data were analyzed via descriptive and analytical methods. Results: The prevalence of depression among the medical students was 5.3%. Fourteen students (4.6%) were mildly depressed while only two respondents had moderate depression. Year 3 had the highest prevalence with 10.5% followed by final year with 5.3%, while the only 2 cases of moderate depression were found among students in year 2 of their medical programme. Two hundred and seventy-one respondents (88.8%) were found to have good knowledge of depression, 32 (10.5%) were found to have average knowledge of depression and 2(0.7%) had poor knowledge of depression. Conclusion: Depression does occur among medical students at the University of Port Harcourt albeit low, and was associated with a number of socio-demographic and other factors. The present medical curriculum and programme should be sustained and more efforts at making it less stressful and academically friendly, be made to further reduce the current rate of psychological stress and depression among the students.

Acute carbon monoxide (CO) poisoning is caused by the inhalation of large quantity of CO within short time leading to morbidity and mortality. In this study, a total of eighteen (18) rabbits were divided into three (3) groups of six (6) animals each. The first group first group was poisoned with CO and labelled carbon monoxide death (CD). The second group of animals was killed prior to exposure to CO and labelled disguised death (DD), while the third was the control group (CG). The vitreous humour samples were collected from all the animals using standard methodologies. The vitreous humour total protein and albumin were estimated while its globulin content and albumin/globulin ratio were derived mathematically. Pearson correlation analyses were used to establish relationships between vitreous protein profile components and the acute graded carbon monoxide concentrations. Results indicated a significant increase (P<0.05) in vitreous total protein and globulin of the studied groups. This observation was more pronounced in the CD group of animals. Therefore the marked elevation of vitreous total protein and globulin may serve as a useful tool in the confirmation of death due to carbon monoxide poisoning.

Patients undergoing laparoscopic surgery had a lower incidence of major complications, such as anastomotic leak, intra-abdominal bleeding, abscess, and evisceration. Controversies about the operative management of left colonic emergencies are decreasing. Nowadays there is worldwide shifting towards primary resection, on table lavage and primary anastomosis. The aim of this study is to record the safety of laparoscopic primary anastomosis in left-sided colonic emergencies. Patients: The study was carried out at Beni-Suef University Hospital, in the period between January 2016 and July 2017. Twenty-six patients were included in this study, twelve with left colon cancer, twelve with left colonic complicated diverticulitis and two cases with sigmoid volvulus. Patients presented clinically with either obstruction or perforation. All patients were subjected to laparoscopic resection, on table lavage and primary anastomosis. Method: Decompression was done prior to starting the intervention, followed by resection and on table lavage then colorectal anastomosis using the circular stapler. The study was approved by the ethical committee in the faculty. Results: Mean operative time: 185 min (160- 245). LOS: 12 (10- 18). Leak: one in obstruction group and two in perforation group. Redo one in perforation group. Conclusion: Emergency laparoscopic left-sided colonic resection and primary anastomosis can be performed with low morbidity, however with caution if there was free perforation with peritonitis

COVID-19 pandemic soon apparently proved to be havoc and a great stressor. During such a stressful time, mental health is in threat. Here, we intend to review the presenting problems/ symptoms as shared in psychiatry helpline of a Teaching Hospital in eastern Nepal during the second week of lockdown and to reflect on to emotional, including mood problems. It is an institute based period observation noted for all psychiatry helpline calls during 1 week of lockdown days of COVID-19. Their concerns and problems were listened and symptoms clarified by a consultant psychiatrist to help them as far as possible through the telephonic conversation. Maintaining the confidentiality, basic information were noted down in a semi-structured proforma to record certain socio-demographic and clinical information (including mood and other emotional symptoms). We received 102 helpline calls of 60 clients for psychiatry in 1 week, from 14 districts. More patients being discussed were males (35/60), average age being 34.15 (15 - 70) years. More patients were regular follow-up cases with some new issues (24/60) and 18/60 each were new clients and regular follow-up cases. Majority had exacerbated symptoms in the wake of COVID-19 as: emotional (47/60; mood 24/60, anxiety/worry 23/60) symptoms along with disturbed sleep (32/60); treatment/service issues (31/60) and changed routines. Most common mental problems were Bipolar affective disorder, Psychosis, Anxiety and Depression and advices included Antipsychotics, Benzodiazepines, Antidepressants, along with some Psycho-education. Most common concerns were about OPD service, worsening symptoms and local unavailability of medicines. Many had mood and emotional symptoms in this stressful time, both simple amenable to telephonic advices and severe requiring to be called to emergency service.

Lipomas are the most common type of soft tissue tumor occurring in the subcutaneous tissue. Rarely, lipomas present in the deep soft tissue such as intermuscular, intramuscular, and parosteal sites. When they occur within a skeletal muscle they are called intramuscular lipomas. Intramuscular lipomas may involve both children and adults. They are benign, nontender, deep located, circumscribed but unencapsulated lesions. Intramuscular lipomas account less than 1% of all lipomas. Most are located within a single muscle (solitary), while cases involving two or more muscles are very rare. They present with typical histological features. They may be divided into the infiltrative, the well-circumscribed and the mixed type. Differential diagnosis of the infiltrative type from liposarcoma is very difficult. Local recurrence may be evident if the surgical margin is not clear. They can occur in almost any anatomical site [1-15].

Background: Herbal essential oil contains pharmacological benefits for intervention treatment of various diseases. Studies have demonstrated its antimicrobial, antioxidant, and anti-inflammatory effect involving in vitro cell culture and preclinical animal models. It has been also traditionally used to reduce anxiety and hypertension in human. However, scientific studies elucidating its mechanism of action and pharmacological targets, as well as its effectiveness and safety as phytotherapeutic compounds are still progressing. Recent studies showed its promising effect in depression-cardiovascular disease intervention. However, comprehensive evaluations to enlighten latest advancement and potential of herbal essential oil are still lacking. Objective: In this systematic review, the depression-cardiovascular effects of herbal essential oil on lipid profile, biochemical and physiological parameters (e.g haemodynamic) are presented. The route of delivery and mechanism of action as well as main bioactive compounds present in respective essential oil are discussed. Methods: Article searches are made using NCBI PubMed, PubMed Health, SCOPUS, Wiley Online, tandfonline, ScienceDirect and Espacenet for relevant studies and intellectual properties related to essential oil, depression and cardiovascular disease. Results: In experimentation involving in vitro, in vivo and clinical trials, herbal essential oil showed its effectiveness in reducing coronary artery disease (narrowing of the arteries), heart attack, abnormal heart rhythms, or arrhythmias, heart failure, heart valve disease, congenital heart disease, heart muscle disease (cardiomyopathy), pericardial disease, aorta disease, Marfan syndrome and vascular (blood vessel) disease. Conclusion: This review gives a valuable insight on the potential of essential oil in the intervention of depression associated with cardiovascular diseases. Studies showed that herbal essential oil could act as vasodepressor, calcium channel blocker, antihyperlipidemia, anticoagulant, antiatherogenesis and antithrombotic. It can be proposed as an interventional therapy for depression-cardiovascular disease to reduce doses and long-term side-effect of current pharmacological approach.
