BACKGROUND: A student enrolled in Allied Health Sciences has a curriculum and academic standards that are different compared to a student enrolled in a medical programme. Nevertheless, little is known about the psychological distress of this population. Our objective was to determine whether psychological distress is prevalent in students enrolled in an Allied Health Sciences programme, as well as factors that contribute to it. METHODS: Three hundred and thirty-three (333) undergraduates studying Allied Health Sciences, ages 18-30, were included in this cross-sectional study. A representative sample of students from nursing, physiotherapy, medical laboratory science, medical radiography, and optometry programmes were selected through a stratified sampling technique. A 21-item Depression Anxiety and Stress Scale (DASS-21  10) was used to collect data on psychological distress indicated by depression, anxiety, and stress. We fitted a multivariate logistic regression to identify factors associated with psychological distress among the participants. RESULTS: As a result of the study, 58.9% reported depression, 66.1% reported anxiety, and 45.1% reported stress. Depression (AOR= 3.23; 95% CI: 1.33- 7.81), anxiety (AOR= 3.33;95% CI:1.34- 8.26) and stress (AOR= 2.58;95% CI: 1.14- 5.85) were associated with family history of mental illness. Poor academic performance was associated with anxiety (OR=2.75; 95% CI: 1.35- 5.61) and stress (OR=2.00; 95% CI: 1.05-3.81). CONCLUSIONS The prevalence of psychological distress among allied health sciences students is high, especially among students with poor academic performance and those with a family history of mental illness. Psychological distress can be prevented with early detection and awareness programmes.

Opioid drugs are the first line of defense in severe pain but the adverse effects associated with opioids are considered as a serious issue worldwide. Acupuncture/electroacupuncture is a type of Chinese medicine therapy which is an effective analgesic therapy, well documented in animals and human studies. Electroacupuncture stimulation could release endogenous opioid peptides causing analgesia in a variety of pain models. It can be used as an alternative therapy to control the opioid crisis.

BACKGROUND: Bendamustine is an attractive option for the management of both de novo and relapsed lymphomas. It is being increasingly used in the conditioning regimen for autologous stem cell transplantation (SCT) and can be an alternative to the traditionally-used carmustine. In this study, we aimed to determine the safety and efficacy of bendamustine in the conditioning regimen for autologous SCT in refractory/relapsed lymphomas. METHODS: We designed a descriptive study to evaluate bendamustine in combination with etoposide, cytarabine, and melphalan (BeEAM) in the conditioning regimen for autologous SCT. RESULTS: Fourteen patients (median age, 28 yr) with Hodgkin's lymphoma (HL) (N=8), non-Hodgkin's lymphomas (NHL) (N=5), or peripheral T-cell lymphoma, not otherwise specified (PTCL NOS) (N=1) were included in the study. A median number of 5.95×10⁶ CD34+ cells/kg were transfused. Median times to absolute neutrophil count and platelet engraftment were 17 days and 24 days, respectively. The 100-day transplantation mortality rate was 28% (4 patients). Eight patients (57.14%) had GII-III acute kidney injury, four patients (28.5%) had GIII-IV hyperbilirubinemia, and twelve patients (85%) had GII-III diarrhea. After 3 months, 37% (5 patients) and 21.4% (3 patients) demonstrated complete response and partial response, respectively. The median follow-up was 5.5 months (15 days–19 mo). At the final follow-up, 7 patients (50%) were alive and in CR. CONCLUSION: Our study showed that bendamustine is a potentially toxic agent in the conditioning regimen for autologous SCT, resulting in significant liver, kidney, and gastrointestinal toxicity. Further studies are required to assess its safety and efficacy at reduced doses.

PURPOSE: Partner and localizer of BRCA2 (PALB2) is a breast cancer susceptibility gene that plays an important role in DNA repair. This is the first study assessing the prevalence of PALB2 mutations in early-onset and familial breast/ovarian cancer patients from Pakistan. MATERIALS AND METHODS: PALB2 mutation screening was performed in 370 Pakistani patients with early-onset and familial breast/ovarian cancer, who were negative for BRCA1, BRCA2, TP53, CHEK2, and RAD51C mutations, using denaturing high-performance liquid chromatography analysis. Mutations were confirmed by DNA sequencing. Novel PALB2 alterations were analyzed for their potential effect on protein function or splicing using various in silico prediction tools. Three-hundred and seventy-two healthy controls were screened for the presence of the identified (potentially) functional mutations. RESULTS: A novel nonsense mutation, p.Y743*, was identified in one familial breast cancer patient (1/127, 0.8%). Besides, four in silico-predicted potentially functional mutations including three missense mutations and one 5' untranslated region mutation were identified: p.D498Y, novel p.G644R, novel p.E744K, and novel c.-134_-133delTCinsGGGT. The mutations p.Y743* and p.D498Y were identified in two familial patients diagnosed with unilateral or synchronous bilateral breast cancer at the ages of 29 and 39, respectively. The other mutations were identified in an early-onset (≤ 30 years of age) breast cancer patient each. All five mutations were absent in 372 healthy controls suggesting that they are disease associated. CONCLUSION: Our findings show that PALB2 mutations account for a small proportion of early-onset and hereditary breast/ovarian cancer cases in Pakistan.

Impalement injuries, is a severe form of trauma, which are not common in civilian life. These injuries rarely occurs in major accidents. Abdomen, chest, limbs and perineum are often involved due to their large surface area. Thoracic impalement injury is usually a fatal injury, due to location of major vessels and heart in the thoracic cavity. These injuries are horrifying to site, but the patients who are lucky enough to make it to hospital, usually survive. Chances of survival are larger in right sided impalement injuries while central injuries are always died at the scene. Our patient, 25 years old male, was brought to the emergency room (ER) with large impaled metallic bar (about 2.5 feet long) in situ, in right sided chest. The patient was immediately shifted to operation room (OR) and was operated, his recovery was uneventful without any sequelae. Such patients should be treated and resuscitated according to advanced trauma life support (ATLS) protocols and operated without any delay for further investigations. Such operations are carried out by the most experienced surgeon team available. The impaled objects should not be processed if not necessary to avoid major hemorrhage and damage to vital structures, until the patient is in operation room. Large size and unusual position of impaled objects, makes the job difficult for surgeons/anesthetists. Although horrifying at scene, patients with thoracic impalement injuries are mostly young and healthy, and those who survive the pre-hospital phase are potentially manageable with proper resuscitation. Usually these patients make recovery without any further complications.

Dengue fever is one of the major health problems in tropical and subtropical areas throughout the world. The causative agent of dengue fever is the dengue virus which is an enveloped single stranded RNA virus belongs to the family Flaviviridae and has five distinct serotypes (DENV-1, DENV-2, DENV-3, DENV-4 and DENV-5). Dengue virus is transmitted to human via bite of Aedes aegypti and Aedes albopictus mosquitoes. The clinical symptoms of dengue fever ranging from mild to severe form as dengue hemorrhagic fever and dengue shock syndrome. Pakistan is dengue endemic since 1994 but from 2006, Pakistan faced the worst condition regarding dengue in which thousands of people affected by the disease and hundreds of people lost their lives. DENV-2, DENV-3 and DENV-1 are the prevalent serotypes in Pakistan. Common diagnostic techniques are being used in Pakistan such as enzyme-linked immunosorbent assay, polymerase chain reaction and rapid diagnostic tests, while differential diagnosis, limitations of diagnostic methods and poor health care system are the real challenges in dengue diagnosis. Favorable climatic conditions, unplanned urbanization, travelling etc., are major factors responsible for dengue epidemics in Pakistan. This presentation provides update about dengue circumstances in Pakistan and also describes the way how to improve dengue situation in Pakistan.

Needle breakage following inferior alveolar nerve block is an unusual yet alarming complication in contemporary dental practice. We report a case of surgical retrieval of a broken needle in the pterygomandibular space following an inferior alveolar block in a 21 years old male. The postoperative recovery was uneventful and no complications were observed. Prompt removal of a broken needle is advisable to avoid complications.

Osteomyelitis of the mandible, a serious complication of untreated odontogenic infection has been reported. This case report describes an interesting presentation of chronic suppurative osteomyelitis (CSO) of the mandible in a 13 years old anaemic male patient. Investigations revealed inversion of his permanent teeth leading to trans-cutaneous extra-oral eruption along with marked destruction of mandible on the affected side. The treatment included a pre surgical course of antibiotics followed by the removal of the retained second premolar tooth, surgical debridement of the affected bone, and resection of the cutaneous sinus tract. The post-operative healing was uneventful. A combination of antibiotic therapy and surgical debridement were effective in the treatment of chronic suppurative osteomyelitis.

Aims: Infections due to metallo-β-lactamase (MBL) producing Gram negative rods are a cause of high mortality and morbidity. Early detection by an economical and accurate method may improve patient outcome. This study was aimed to evaluate the diagnostic accuracy of combined disc method for MBL detection by comparing it with MBL-Etest. Methodology and Results: This cross-sectional, validation study was carried out in the Department of Microbiology, Army Medical College, National University of Sciences and Technology, Rawalpindi, over a period of six months. A total of 52 non-duplicate Gram-negative rods isolated from the routine clinical specimens and found resistant to meropenem/imipenem on Kirby Bauer Disc Diffusion method were subjected to two tests for metallo-β-lactamase detection. One was combined Disc test using imipenem with Ethylene Diamine Tetraacetic Acid (EDTA), where a strain showing an increase in zone of inhibition of combined disc of ≥ 7 mm as compared to imipenem alone, was considered as MBL producer and the other one was MBL-Etest for which results were interpreted as per manufacturer’s guidelines. Combined disc method for MBL detection was found to have a sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 97.5%, 100%, 100%, 92% and 98%. Conclusion, Significance and Impact of study: Combined disc method is an economical and reliable method for metallo-β-lactamase detection which can be used routinely in any laboratory.

Microorganisms adhere to non-living material or living tissue, and form biofilms made up of extracellular polymers/slime. Biofilm-associated microorganisms behave differently from free-floating bacteria with respect to growth rates and ability to resist antimicrobial treatments and therefore pose a public health problem. The objective of this study is to detect the prevalence of biofilm producers among Gram positive and Gram negative bacteria isolated from clinical specimens, and to study their antimicrobial susceptibility pattern. The study was carried out from October 2009 to March 2010, at the Department of Microbiology, Army Medical College/ National University of Sciences and Technology (NUST), Rawalpindi, Pakistan. Clinical specimens were received from various wards of a tertiary care hospital. These were dealt by standard microbiological procedures. Gram positive and Gram negative bacteria isolated were subjected to biofilm detection by congo red agar method (CRA). Antimicrobial susceptibility testing of those isolates, which showed positive results (slime production), was done according to the Kirby-Bauer disc diffusion technique. A total of 150 isolates were tested for the production of biofilm/slime. Among them, 81 isolates showed positive results. From these 81, 51 were Gram positive and 30 were Gram negative. All the 81(54%) slime producers showed reduced susceptibility to majority of antibiotics. Bacterial biofilms are an important virulence factor associated with chronic nosocomial infection. Detection of biofilm forming organisms can help in appropriate antibiotic choice.
