Kidney Biopsy Un-masquerading Plasma Cell Leukemia Diagnosed as Acute Myeloid Leukemia: An Unusual Clinical Experience.

Plasma cell leukemia (PCL) is a rare aggressive variant of plasma cell myeloma. The differential diagnosis of PCL includes multiple myeloma (MM), other leukemias, and lymphomas with abnormal cells circulating in the peripheral blood. In addition, infectious or autoimmune diseases can cause reactive polyclonal plasmacytosis, which could confuse us with PCL occasionally. Sometimes, blastoid morphology can cause confusion in diagnosis, and immunohistochemistry is needed to differentiate PCL from other forms of leukemias and lymphomas. Here, we present a rare case of PCL diagnosed as acute myeloid leukemia (AML) with kidney biopsy establishing the correct diagnosis.

Efficacy of Radioiodine Therapy in Patients With Primary Hyperthyroidism: An Institutional Review From Pakistan.

Background Radioactive iodine (RAI) is the treatment of choice for most patients with primary hyperthyroidism. The most common etiologies of hyperthyroidism are Graves' disease (GD), toxic adenoma (TA), and toxic multinodular goiter (TMNG). A single dose of RAI is usually sufficient to cure hyperthyroidism. The aim of this study was to assess the effectiveness of RAI therapy for patients diagnosed with primary hyperthyroidism. Methods and materials Patients diagnosed with hyperthyroidism who received RAI therapy between 2008 and 2018 were included in the study. The data was acquired from the hospital's electronic medical record system. Following the RAI treatment, a cure was defined as the development of euthyroidism or hypothyroidism after a single fixed-dose without antithyroid medication within one year of RAI therapy. In addition, a simple logistics regression model was used to identify the prognostic factors that may lead to better outcomes. Results A total of 112 patients diagnosed with hyperthyroidism with a mean age of 47 ± 14 were included in this study. The majority of the patients were female, 79 (70.5%). Within one year of RAI therapy, 84 (75%) patients achieved a cure that is either hypothyroid or euthyroid status. RAI dose was higher in responsive patients (18.50 ± 4.10 millicurie [mCi] versus 16.50 ± 4.10 mCi) than in non-responsive patients. The mean RAI doses were 16.05 ± 2.99 mCi in GD, 19.81 ± 4.40 mCi in TMNG, and 20.50 ± 3.30 mCi in TA, with a statistically significant p-value of 0.001. In the univariable logistic regression model, RAI dose was a significant prognostic factor of the responsive group (OR: 1.15, CI [1.01-1.31], p-value 0.03). Conclusion Our data presented that RAI therapy is effective for primary hyperthyroidism. We achieved remission with a single fixed-dose in the majority of patients. Most of our patients were cured within three months of RAI therapy. In addition, the RAI dose was higher in the responsive group as compared to the non-responsive group.

An Unusual Cause of Right Heart Failure: Hemorrhagic Pericardial Cyst Presenting as a Pericardial Mass and Constrictive Pericarditis.

Congenital pericardial cysts are very rare neoplasms of the middle mediastinum. We report a case of a young woman who was referred to the surgical department with abdominal pain. The ultrasound done showed moderate ascites and pleural effusion. Further evaluation with computed tomography (CT) chest revealed a calcified mass in the pericardium. Follow-up echocardiography showed an echogenic mass in the pericardium. Magnetic resonance imaging (MRI) revealed a hyperintense mass with a delayed enhancement of the contents with features of right heart failure. So, an emergency surgical resection was done that showed a large hemorrhagic mass with pultaceous material in the pericardial cavity. The pathological report confirmed the diagnosis of a hemorrhagic pericardial cyst with organized material.

Mapping and population size estimates of people who inject drugs in Afghanistan in 2019: Synthesis of multiple methods.

INTRODUCTION: Mapping and population size estimates of people who inject drugs (PWID) provide information needed for monitoring coverage of programs and planning interventions. The objectives of this study were to provide the locations and numbers of PWID in eight cities in Afghanistan and extrapolate estimates for the country as a whole. METHODS: Multiple population size estimation methods were used, including key informant interviews for mapping and enumeration with reverse tracking, unique object and service multipliers, capture-recapture, and wisdom of the crowds. The results of the several methods were synthesized using the Anchored Multiplier-a Bayesian approach to produce point estimates and 95% credible intervals (CI). Using the prevalence of PWID in the eight cities and their correlation with proxy indicators, we extrapolated the PWID population size for all of Afghanistan. RESULTS: Key informants and field mapping identified 374 hotspots across the eight cities from December 29, 2018 to March 20, 2019. Synthesizing results of the multiple methods, the number of male PWID in the eight study cities was estimated to be 11,506 (95% CI 8,449-15,093), corresponding to 0.69% (95% CI 0.50-0.90) of the adult male population age 15-64 years. The total number of women who injected drugs was estimated at 484 (95% CI 356-633), corresponding to 0.03% (95% CI 0.02-0.04) of the adult female population. Extrapolating by proxy indicators, the total number of PWID in Afghanistan was estimated to be 54,782 (95% CI 40,250-71,837), men and 2,457 (95% CI 1,823-3,210) women. The total number of PWID in Afghanistan was estimated to be 57,207 (95% CI 42,049-75,005), which corresponds to 0.37% (95% CI 0.27-0.48) of the adult population age 15 to 64 years. DISCUSSION: This study provided estimates for the number of PWID in Afghanistan. These estimates can be used for advocating and planning services for this vulnerable at-risk population.

Reasons for Admission and Outcome to an Acute Palliative Care Unit in Patients with Advanced Malignancy in a Cancer Hospital.

Introduction: The alleviation of suffering is a primary goal of palliative care team for patients with terminal cancer. In some cases, patients experience symptoms requiring inpatient care. The purpose of this investigation was to assess the clinical presentation and outcomes of hospitalisation in patients that were admitted to the acute palliative care service. Materials and Methods: This is a retrospective descriptive study looking at admissions to an acute palliative care unit in a single centre over a 24-month period. Medical records of all patients, admitted in palliative care unit from 1 January, 2013, to 31 December, 2014, were reviewed for reason of admission and outcome. Results: A total of 226 patients were identified and included in the present investigation. Among these, 55.5% (125) were females. The median age of the cohort was 48 (15-86) years. The most common reasons for admission were alteration in consciousness (19.5%), respiratory tract infection (18%), diarrhoea and/or vomiting (14.2%) and respiratory distress (not related to infection) (13.4%). The median duration of hospital stay was 4 (0- 27) days. The majority of the patients were discharged home (65.1%). However, a significant portion (33.1%) of the patients did not survive the hospitalisation. Following discharge from the hospital, at 4-weeks follow-up, the survival rate was 38.7%. This dropped to 21.7% at 8-weeks. Conclusion: Patients with advanced disease have a multitude of reasons to seek acute inpatient care. The majority of the patients were discharged following care. However, the survival rate of patients following discharge was low.

Development of nanoparticle-assisted PCR assay in the rapid detection of brain-eating amoebae.

Brain-eating amoebae (Acanthamoeba spp., Balamuthia mandrillaris, Naegleria fowleri) have gained increasing attention owing to their capacity to produce severe human and animal infections involving the brain. Early detection is a pre-requisite in successful prognosis. Here, we developed a nanoPCR assay for the rapid detection of brain-eating amoebae using various nanoparticles. Graphene oxide, copper and alumina nanoparticles used in this study were characterized using Raman spectroscopy measurements through excitation with a He-Ne laser, while powder X-ray diffraction patterns were taken on a PANanalytical, X'Pert HighScore diffractometer and the morphology of the materials was confirmed using high-resolution transmission electron microscopy (HRTEM). Using nanoparticle-assisted PCR, the results revealed that graphene oxide, copper oxide and alumina nanoparticles significantly enhanced PCR efficiency in the detection of pathogenic free-living amoebae using genus-specific probes. The optimal concentration of graphene oxide, copper oxide and alumina nanoparticles for Acanthamoeba spp. was determined at 0.4, 0.04 and 0.4 µg per mL respectively. For B. mandrillaris, the optimal concentration was determined at 0.4 µg per mL for graphene oxide, copper oxide and alumina nanoparticles, and for Naegleria, the optimal concentration was 0.04, 4.0 and 0.04 µg per mL respectively. Moreover, combinations of these nanoparticles proved to further enhance PCR efficiency. The addition of metal oxide nanoparticles leads to excellent surface effect, while thermal conductivity property of the nanoparticles enhances PCR productivity. These findings suggest that nanoPCR assay has tremendous potential in the clinical diagnosis of parasitic infections as well as for studying epidemiology and pathology and environmental monitoring of other microbes.

Unicentric Castleman's disease located in the scapular region.

Castleman's disease (CD) or giant node hyperplasia is a rare benign disease of unknown etiology characterized by lymphoid hyperplasia. Although the most common site of the disease is the mediastinum, very few cases occurring in lymph nodes elsewhere have been reported in English literature, including only 10 intramuscular cases. We report a case of unicentric CD of the hyaline vascular type in a 30 year female located in the right scapular region. This case has been reported due to its extreme rarity and also highlights the need for including CD in the differential diagnosis of soft-tissue tumors.

Effect of risk factors like age, gender, hypertension, diabetes, smoking, dyslipidemia on coronary artery disease in Karachiites with angiographical data of local population: Number, site, severity of coronary lesion.

The aim of this study was to determine the effect of major risk factors like age, gender, hypertension, diabetes, smoking, dyslipidemia on coronary artery disease in Karachiites and highlighted the angiographic data of local population like number of vessels involvement, site and severity of coronary lesions. This was a cross sectional analytical prospective study which was carried out at Abbasi Shaheed Hospital Karachi from August 2004 - July 2014. We includedfive hundred (500) consecutive patients (188 female & 312 male) between 26-80 years old, who came for coronary angiography with suspecting ischemic heart disease clinically or otherwise proven by relevant tests like ETT, ECHO, and Thallium stress test. Post PCI and CABG patients were excluded from study. During this study variables like age, gender, hypertension, diabetes, smoking and dyslipidemia were taken into account in relation to coronary artery disease in Karachiites. In addition we also assorted some important findings of coronary angiography like: number of vessels involved, site and severity lesions in our population and compared them with existing literature. Our study revealed that in our local population not only old age and male gender are potential threat for an early coronary artery disease but other variables like hypertension, diabetes, smoking, and dyslipidemia are also playing important role in coronary artery disease. It is also concluded that our population is more prone to multiple vessels involvement with almost involvement of LAD in majority of population.

Cyto-histopathological and Clinical Correlation of Pilomatricomas: A 4 Year Study.

AIM: The aim of the following study is to characterize the cytological features of pilomatricomas (PMXs) on fine-needle aspiration (FNA) and correlate with the histopathological features. MATERIALS AND METHODS: FNA, histopathological and clinical diagnosis of 12 cases of PMXs were analyzed. Clinical, aspiration findings and histopathological features were correlated with histopathological diagnosis which was taken as the gold standard. A written consent was taken from patients or parents as appropriate. Morphological features of both aspiration as well as histopathological features were graded. The study was duly approved by the Hospital Scientific Review Committee. RESULTS: Out of the 7600 cases studied retrospectively over a period of 4 years, only 12 cases were diagnosed as PMXs. These tumors were mainly located in the head and neck region and mostly affected young females (median age 9.5 years). The mean size of these lesions was 0.9 cm. Out of the 12 histopathologically proven cases of PMX, the correct clinical diagnosis was given in only one case while cytopathological diagnosis was achieved in four cases. CONCLUSION: PMX is a rare tumor, which is mostly found in the pediatric age group. The clinical features should be keenly observed. Keeping in mind the diagnostic pitfalls a cytopathologist may encounter, histopathology should be regarded as the gold standard for diagnosis.

Spontaneous cholecystocutaneous fistula.

We report a case of cholecystocutaneous fistula in a 90 years old female as a complication of gallstone disease. Patient presented with necrotizing fasciitis of anterior abdominal wall and cholecystocutaneous fistula. She was bedridden for the last 3 years due to cerebral vascular accident. She was a known case of chronic cholecystitis and 2 years back common bile duct stenting was done, in Jeddah, for obstructive jaundice but cholecystectomy was not done because patient was not fit for surgery.
