A Rare Case of Cutaneous Metastasis of Unresectable Rectal Adenocarcinoma.

Colorectal cancer (CRC) is the third most common malignancy. Common metastatic sites for colorectal carcinoma are the lung and liver while cutaneous metastases are extremely rare. Skin metastasis may be an early manifestation of metastatic disease and represents a poor prognosis. Here we present a case of metachronous skin metastasis during chemoradiation treatment in a patient with locally advanced rectal cancer. A young boy aged 19 years presented to our hospital with radiological TNM staging of T3c N1 M0 with circumferential resection margin (CRM) involved. The treatment plan was defunctioning colostomy with neoadjuvant chemotherapy and radiotherapy with a later plan for surgery. Seven months later, there is a focal skin nodule in the nape of the neck. A core biopsy of this cutaneous nodule was done and proved metastatic. Surgery for the primary tumor and oligometastatic site was planned but due to extensive primary tumor, surgery was terminated and continues with chemotherapy and reassessment.

Human amniotic epithelial cells (HAECS); a potential cell type for the hepatic disorders.

OBJECTIVE: To isolate a homogenous population of human amniotic epithelial cells (hAECs) from the amniotic membrane of the human placenta and differentiate them into hepatic-like cells with the help of small molecules. METHODS: hAECs were isolated by using the enzymatic digestion method and characterized for the presence of specific stem cell markers. In-vitro, hepatic differentiation of hAECs was carried out by using a combination of small molecules. Differentiated cells were observed under a live cell imaging microscope for morphological changes followed by gene and protein expression analysis by qPCR and immunocytochemistry respectively. RESULTS: The isolated hAECs attained characteristic cuboid epithelial shape and express stem cells marker. The hepatic differentiation method was optimized based on soluble chemical compounds supplied in the culture medium. The differentiated hAECs phenotypically acquire hepatic-like cell features and expressed hepatic markers as well as hepatic protein albumin at immature levels. CONCLUSIONS: The isolated population of hAECs is highly proliferative. Moreover, hepatic markers expression in the isolated hAECs makes them an exclusive source for the treatment of chronic liver diseases.

A prospective observational study of estimating drug related problems and clinical outcomes in subtypes of stroke patients.

BACKGROUND: Stroke is a neurological disease and a leading cause of mortality worldwide. Strokes mainly consist of two types: hemorrhage and ischemia. Stroke patients are being administered multiple drug therapy and are at risk of drug-related problems. AIM: To estimate drug-related problems (DRPs) and clinical end outcomes in hospitalized stroke patients. METHODS: Current study was a multicenter, cross-sectional prospective observational study including 250 stroke patients admitted to tertiary care hospitals in Karachi, Pakistan. The study included all clinical subtypes of stroke patients i.e. Stroke, Ischemic stroke, Hemorrhagic stroke, CVA, and TIA. Associations among patient-clinical end outcomes and drug therapy-related variables like DRPs, mortality, and morbidity rates were estimated using Pearson's chi-squared test. Statistical analysis was done by using SPSS software, version 25. RESULTS: A total of 250 patients participated in this study suffering from different clinical subtypes of stroke i.e. Ischemic stroke, hemorrhagic stroke, TIA, and CVA, including 46% male and 54% female patients. The majority of patients' stay at the hospital was between 1-10 days. The overall mortality rate in stroke patients was 51%. HAIs were observed in 70% of patients, HAIs faced by patients were SAP, CAP, UTI, sepsis, and VAP. Drugs were assessed according to NEML i.e. access group antibiotics, watch group antibiotics, reserve group antibiotics, statins, antiepileptics, and proton pump inhibitors. Majorly ceftriaxone was administered to 79% of patients, piperacillin-tazobactam to 52%, and cefixime to 48%, whereas meropenem was administered to 42% of patients along with vancomycin to 39% of total patients. A high mortality rate was observed in the case of Klebsiella pneumoniae and Staphylococcus aureus i.e. 78% and in the case of streptococcus pneumoniae 61% mortality rate was observed. Due to the presence of DRPs and various other clinical factors like comorbidities, DDIs, HAIs, administration of potentially nephrotoxic drugs, and administration of antibiotics without having CST, hospitalized stroke patients faced many problems. CONCLUSION: This study helped determine DRPs along with various clinical factors affecting the clinical end outcomes of patients suffering from any clinical subtype of stroke. Due to the enhancement in the evidence of the incidence of DRPs in tertiary care hospitals, pharmacist-led drug therapy review by interfering with doctors and other medical professionals at the patient bed site is needed and should be done to avoid any negative end outcomes and serious issues related to DRPs.

Assessment of potential drug-related problems (PDRP) and clinical outcomes in bacterial meningitis patients admitted to tertiary care hospitals.

Meningitis is an important cause of morbidity and mortality in children and adults. Its treatment strategy varies with age and gender. To assess potential drug-related problems (PDRP) and clinical outcomes in bacterial meningitis patients, a multicenter, clinical, descriptive, cross-sectional prospective observational study in 120 patients admitted to different tertiary care hospitals in Karachi was conducted. It includes both males 48% and females 52% belonging from all age groups i.e. peadiatrics (01 to 12 years), adults (18 to 65 years), and geriatrics (66 to 75 years). Out of these 72 patients were admitted in the public sector and 48 patients were admitted in private sector hospitals. Nosocomial infections were developed in 41% of patients during their stay at the hospital. Potentially nephrotoxic drugs were administered to all BM patients, these drugs should be administered carefully. Majorly Ceftriaxone was administered to 86% of patients, Vancomycin 71%, and meropenem 73% whereas 68% of patients were administered piperacillin-tazobactam. Organisms involved as causative agents in the majority of patients are Neisseria meningitides, Pseudomonas aeruginosa and, Streptococcus pneumoniae. DRPs impacted patient clinical outcomes in presence of many other factors like comorbidities, DDIs, Nis, administration of potentially nephrotoxic drugs, and administration of watch group and reserve group antibiotics without having culture sensitivity test, even after having CST no principles of de-escalation for antibiotics were done, which is a very important factor for hospitalized patients having IV antibiotics. The mortality rate among BM patients was 66%. The majority of patients (87%) stay at the hospital was 1-10 days. The present study helped in the identification of DRPs along with some other factors affecting the clinical outcomes in patients suffering from bacterial meningitis. Healthcare professionals should receive awareness and education on the importance of CST before initiating antibiotic therapy. Pharmacist-led medication review is necessary and should be followed to avoid negative outcomes and serious consequences related to DRPs.

A Rare Case of Primary Intracerebral Malignant Melanoma.

Malignant melanomas occurring in the central nervous system are mostly metastatic. Primary intracranial malignant melanomas are a rare entity, accounting for 0.07% of all brain tumors. In the central nervous system, melanocytes originate from the neural crest cells that are found in the leptomeninges. Only a few cases of malignant melanoma primarily arising from the brain have been reported in the literature to date. We report a rare case of primary intracerebral malignant melanoma in a 39-year-old female. Through this case report, our aim is to highlight the role of imaging in the early diagnosis and management of malignant melanoma.

Corpus Callosum Infarct in the Background of Varicella-Zoster Infection: A Report of a Rare Case.

Infarctions of the corpus callosum are rare due to a rich blood supply. Corpus callosum derives its blood supply from four vessels from the anterior and posterior circulation and for this reason, they have a rare, atypical presentation. There is scarce literature regarding this pathology. Corpus callosum infarcts usually present with non-specific signs and symptoms. Here, we describe a case of corpus callosum infarction in a 5-year-old boy who was a known case of acute lymphoblastic leukaemia. He presented with disseminated varicella infection and developed tonic-clonic seizures. MRI brain was performed and a diagnosis of corpus callosum infarct was made. The patient was treated conservatively.

A Rare Case of Bilateral Orbital Metastases From Rectal Adenocarcinoma.

Colorectal carcinoma is among the commonest malignancies in the World. However, metastases from rectal carcinomas to the orbit are extremely rare. Only a few such cases have been reported in the literature till date. We report a case of adenocarcinoma of the rectum in a 27-year-old male with bilateral orbital metastases who is currently undergoing palliative radiotherapy. Our aim is to highlight the role of imaging in the diagnosis and management of orbital metastatic disease.

Pituitary Stalk Interruption Syndrome: A Case Report.

Pituitary stalk interruption syndrome is a congenital abnormality. The triad of this syndrome comprises a thin pituitary stalk, an ectopic posterior pituitary gland, and an absent or hypoplastic anterior pituitary gland. The patient typically presents with a spectrum of symptoms secondary to anterior pituitary hormonal deficiency. The etiology of this syndrome is not established but is likely due to a genetic mutation. The prognosis is good if the syndrome is diagnosed early and hormonal therapy is started promptly. Early diagnosis is crucial in preventing adverse effects on growth and development. The diagnosis of pituitary stalk interruption syndrome is based on magnetic resonance imaging (MRI) findings. This study presents the case of a young girl who presented with complaints of short stature and amenorrhea and was diagnosed with pituitary stalk interruption syndrome following an MRI.

Comparison Of Anaesthetic Efficacy Of Articaine And Lidocaine In Nonsurgical Endodontic Treatment Of Permanent Mandibular Molars With Symptomatic Irreversible Pulpitis. A Randomized Clinical Trial.

BACKGROUND: Inferior Alveolar Nerve Block (IANB) with Buccal Infiltration (BI) anaesthesia is required to completely anesthetize the mandibular molars with symptomatic irreversible pulpitis. 4% Articaine and 2% Lidocaine provide local anaesthesia during the nonsurgical endodontic treatment of mandibular molars with symptomatic irreversible pulpitis. Objective of the study was to compare the effect of Articaine and Lidocaine in the combination of Inferior alveolar nerve block with buccal infiltration anaesthesia during the nonsurgical endodontic treatment of mandibular molars with symptomatic Irreversible Pulpitis. METHODS: One hundred and sixty participants with Symptomatic Irreversible Pulpitis of permanent mandibular molars were divided randomly in two groups. Group A was given Articaine 4% IANB along with BI whereas group B was given Lidocaine 2%. Pain was assessed after 15 minutes of administration of local anaesthesia. Anaesthetic success of the agents is defined as, absence of pain or mild pain first during the access cavity preparation then instrumentation of the canals of tooth. Chi-square test was applied to analyse data for statistical significance. RESULTS: Anaesthetic success of Articaine was 96.2% during access cavity preparation compared to Lidocaine (86.2%). Success during instrumentation of canals was also found to be high in Articaine (90.2%) compared to Lidocaine (76.2%). This difference of anaesthetic efficacy between Articaine and Lidocaine was found statistically significant. (p=0.02). CONCLUSIONS: Articaine is found to be better than Lidocaine regarding anaesthetic efficacy and hence, it can be a safer alternative to Lidocaine.

Comparative Analysis of Different Local Anesthetic Solutions Available in Market: An In Vitro and Clinical Study.

OBJECTIVES: This study aimed to evaluate and compare various commercially available local anesthetic solutions. MATERIALS AND METHODS: A total of 150 commercially available local anesthetic cartridges of similar composition (2% lidocaine with epinephrine 1:100,000) were randomly collected and divided into 3 groups. The designations of groups were selected from their product names such that each group consisted of 60 cartridges. Group S (Septodont, France) Group M (Medicaine, Korea) and Group H (HD-Caine, Pakistan). The samples were divided into five sub-groups, each consisting of 10 cartridges from each group to investigate each parameter. RESULTS: The acquired data was statistically analyzed and compared (using SPSS version 12). Compositional analysis revealed a non-significant (P>0.05) difference when the three Groups were compared with standard lidocaine and epinephrine solutions. The mean pH values of samples from group S, M, and H respectively fell within the range of pH values of commercially available solutions. Non-significant difference in EPT values of Group S and H was found when efficacy was compared (p = 0.3), however a significant difference (p < 0.01) was observed in contrast to Group M. Anti-bacterial activity was observed in all the group and a non-significant difference in cell viability values of Group S and M was found (p = 0.6), while the difference was significant in comparison to Group H. CONCLUSION: Within the limitations of these investigations, it appears that the properties of different manufacturers fall within the recommended ranges as mentioned in literature and do not appear to be statistically different in the variables we have tested.

Serious Inadequacies in High Alert Medication-Related Knowledge Among Pakistani Nurses: Findings of a Large, Multicenter, Cross-sectional Survey.

INTRODUCTION: Deaths-related to medications errors are common in Pakistan but these are not accurately reported. Recently, the death of a 9 months old baby due to abrupt administration of 15% potassium chloride injection sparked the issue of high alert medications (HAMs) related errors in the country. Since drug administration is the prime responsibility of the nurses, it is pivotal that they possess good knowledge of HAMs. Since there is no published data regarding the knowledge of HAMs among Pakistani nurses, we aimed to assess knowledge of HAMs among registered nurses of Pakistan. METHODS: A cross-sectional study was conducted among registered nurses, recruited using a convenient sampling technique, from 29 hospitals all over the Punjab Province. Data were collected using a validated self-administered instrument. All data were entered and analyzed using SPSS version 22. RESULTS: The study sample was comprised of 2,363 registered nurses (staff nurses = 94.8%, head nurses = 5.2%). Around 63% were working in tertiary hospitals whereas almost 25 and 12% were from district headquarter hospitals and tehsil headquarter hospitals, respectively. Around 84% of the study participants achieved scores <70%, indicating majority of Pakistani nurses having poor knowledge of HAMs administration as well as regulation. There was no significant difference of overall knowledge among age, hospitals, departments, training, designations, qualification, and experience categories. Major obstacles encountered during HAMs administration were "getting uncertain answers from colleagues" (72.9%), "unavailability of suitable person to consult" (61.1%) and "receiving verbal orders" (55.6%). CONCLUSION: Our study revealed the serious inadequacies in HAMs knowledge among Pakistani nurses which may lead to adverse patient outcomes. Nurses should receive comprehensive pharmacology knowledge not only during in-school nursing education but also as hospital-based continuing education. Moreover, it is of immense importance to bridge the gaps between physicians, clinical pharmacists, and nurses through effective communication as this will help reduce medication errors and improve patient care.

A roadmap to develop dementia research capacity and capability in Pakistan: A model for low- and middle-income countries.

OBJECTIVE: To produce a strategic roadmap for supporting the development of dementia research in Pakistan. BACKGROUND: While global research strategies for dementia research already exist, none is tailored to the specific needs and challenges of low- and middle-income countries (LMIC) like Pakistan. METHODS: We undertook an iterative consensus process with lay and professional experts to develop a Theory of Change-based strategy for dementia research in Pakistan. This included Expert Reference Groups (ERGs), strategic planning techniques, a "research question" priority survey, and consultations with Key Opinion Leaders. RESULTS: We agreed on ten principles to guide dementia research in Pakistan, emphasizing pragmatic, resource sparing, real-world approaches to support people with dementia, both locally and internationally. Goals included capacity/capability building. Priority research topics included raising awareness and understanding of dementia, and improving quality of life. CONCLUSION: This roadmap may be a model for other LMIC health ecosystems with emerging dementia research cultures.

A case of non-surgical pneumoperitonium: gas under the diaphragm.

A 58-year-old woman presented with an unexpected episode of vomiting and an acute abdomen. The patient mentioned a vague history of decreased appetite dyspepsia and constipation. Abdominal X-Ray revealed gas under diaphragm. An Open laparotomy was carried out to evacuate the free gas trapped under the diaphragm. The condition is almost always associated with perforation of abdominal viscera and accumulation of air during surgical or gynaecological procedures or peritoneal dialysis. In the reported case, laparotomy revealed no sign of perforation in GIT, uterine fundus or fistulas and nor did the have patient have any history of surgical or gynaecological procedures. This lead to suggestion of spontaneous or non-surgical pneumoperitonium which is extremely rare. Extensive investigations revealed no known cause pneumoperitonium making our case rare and unique.
