Outcomes of Extended Curettage with and without Bone Allograft for Grade II Giant Cell Tumors around the Knee. A Retrospective Comparative Study.

Objective This is the first study to establish the utility of extended curettage with or without bone allograft for Grade II giant cell tumors GCTs around the knee joint with the aim of exploring postoperative functional outcomes. Methods We retrospectively reviewed 25 cases of Campanacci grade II GCTs undergoing extended curettage between January 2014 and December 2019. The participants were divided into two groups: one group of 12 patients underwent extended curettage with bone allograft and bone cement, while the other group of 13 patients underwent extended curettage with bone cement only. Quality of life was assessed by the Revised Musculoskeletal Tumor Society Score and by the Knee score of the Knee Society; recurrence and complications were assessed for each cohort at the last follow-up. The Fisher test and two-sample t-tests were used to compare the categorical and continuous outcomes, respectively. Results The mean age was 28.09 (7.44) years old, with 10 (40%) males and 15 females (60%). The distal femur and the proximal tibia were involved in 13 (52%) and in 12 (48%) patients, respectively. There was no significant difference in the musculoskeletal tumor society score (25.75 versus 27.41; p = 0.178), in the knee society score (78.67 versus 81.46; p = 0.33), recurrence (0 versus 0%; p = 1), and complications (25 versus 7.69%; p = 0.21). Conclusions Extended curettage with or without bone allograft have similar functional outcomes for the knee without any major difference in the incidence of recurrence and of complications for Grade II GCTs. However, surgical convenience and cost-effectiveness might favor the bone cement only, while long-term osteoarthritis prevention needs to be investigated to favor bone allograft.

Resumo Objetivo Este é o primeiro estudo a estabelecer a utilidade da curetagem estendida com ou sem enxerto ósseo em tumores de células gigantes (TCGs) de grau II na articulação do joelho com o objetivo de explorar os resultados funcionais pós-operatórios. Métodos Revisamos retrospectivamente 25 casos de TCGs de grau II de Campanacci submetidos a curetagem estendida entre janeiro de 2014 e dezembro de 2019. Os participantes foram divididos em 2 grupos: um grupo de 12 pacientes foi submetido a curetagem estendida com aloenxerto ósseo e cimento ósseo, enquanto o outro grupo, com 13 pacientes, foi submetido a curetagem estendida apenas com cimento ósseo. A qualidade de vida foi avaliada pela Pontuação Revista da Musculoskeletal Tumor Society (MTS, na sigla em inglês) e pela Pontuação da Knee Society (KS, na sigla em inglês), enquanto as taxas de recidiva e complicações foram avaliadas em cada coorte na última consulta de acompanhamento. O teste de Fisher e os testes t de duas amostras foram usados para comparação de resultados categóricos e contínuos, respectivamente Resultados A média de idade dos pacientes foi de 28,09 (7,44) anos; 10 (40%) pacientes eram do sexo masculino e 15 (60%) pacientes eram do sexo feminino. O fêmur distal e a tíbia proximal foram acometidos em 13 (52%) e 12 (48%) dos pacientes, respectivamente. Não houve diferença significativa na pontuação revista da MTS (25,75 versus 27,41; p= 0,178), na pontuação da KS (78,67 versus 81,46; p= 0,33) e nas taxas de recidiva (0 versus 0%; p= 1) e complicações (25 versus 7,69%; p= 0,21). Conclusões A curetagem estendida com ou sem aloenxerto ósseo tem resultados funcionais semelhantes em pacientes com TCGs de grau II no joelho, sem qualquer diferença importante na incidência de recidivas e complicações. No entanto, a conveniência cirúrgica e o custo-benefício podem favorecer a utilização apenas de cimento ósseo, enquanto a prevenção da osteoartrite em longo prazo precisa ser investigada para favorecer o enxerto ósseo.

Post-partum Thrombotic Thrombocytopenic Purpura with Puerperal Sepsis- A Case Report.

Introduction: Post-partum TTP is an uncommon thrombotic microangiopathy affecting about 1 in 200,000 pregnancies in contrast to preeclampsia and HUS, which have been reported commonly. Case presentation: We report a case of a postpartum TTP following purpureal sepsis. The patient was brought with per vaginal bleed, vomiting, chest pain, yellow discoloration of sclera, and abdominal discomfort following a spontaneous vaginal delivery two days back at a hospital. Clinical findings and investigations: The workup revealed anemia and thrombocytopenia with deranged PT/INR. The renal profile deteriorated over one day and she also developed psychosis. Additionally, schistocytes were observed on the peripheral blood smear. Interventions and outcome: The patient was subsequently treated with dialysis followed by plasmapheresis in addition to the antibiotics after the diagnosis of TTP and made a complete recovery. Relevance and impact: 25% of TTP occurs in the intra or postpartum period. It is thus pivotal to keep it among differentials and intervened timely to reduce morbidity and mortality. Vigilance is required to prevent any relapse in subsequent pregnancies.

Quantitative Analyses of Skin Cancer Research in Pakistan.

In order to investigate the current status of skin cancer research output in Pakistan, International (PubMed) and national (PakMediNet) scientific databases were searched using variety of keywords to retrieve relevant publications. A strict inclusion criterion was applied to select skin cancer publications for final analyses. Data were recorded by two authors and consistent data were entered into SPSS and Microsoft Excel and analyzed for annual growth rate and frequencies. Of 116 articles that were finally included in the study, 74 were original articles, 24 were case-reports, 10 were review articles, three were editorials, two were research communications and one each of case-series, correspondence and response to letter to the editor. The first article on skin cancer from Pakistan was published in 1976 whereas the last article included in our study was published in December 2018. Excluding Karachi, most of the cities have no contribution in the field of skin cancer. Since 1976 to date, the average number of publications per year has been low, with only 2.7 publications per year. Skin cancer research is alarmingly scarce in Pakistan. This calls for immediate attention by all concerned to contribute and devise appropriate measures towards skin cancer research in Pakistan.

Epidemiological and Clinical Features of SARS-CoV-2: A Retrospective Study from East Karachi, Pakistan.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread to almost every country on the globe, and each country is reporting the symptomatic presentation of their patients to give better insight into the various clinical presentations of SARS-CoV-2. However, the epidemiological literature from Pakistan is scanty. Methods We retrospectively analyzed data from 412 patients who were residents of East Karachi and tested positive for SARS-CoV-2 between February 26 to April 24, 2020. Patients' demographics, symptoms, travel and contact history, and outcomes were recorded. All statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 22 (IBM SPSS Statistics for Windows, IBM Corp, Armonk, NY). Results Most of the patients were male (64.6%), the majority (43.3%) belonging to the 21- to 40-year age group. Most of the patients (65.5%) were residents of Gulshan Iqbal. A total of 15.8% of the patients were admitted to the hospital, and 3.9% of patients expired. The three most common presenting symptoms were fever (74.8%), cough (60.4%), and flu (35.5%). The majority of patients (89.3%) gave a history of contact with SARS-CoV-2 patients. Conclusion The number of SARS-CoV-2 cases is rapidly increasing in Karachi, Pakistan. There is a need to educate the population about the most common sign and symptoms of the virus so that individuals can identify these symptoms and get themselves tested. The concerned authorities should devise an adequate and effective plan to flatten the infectivity curve.

Anthropometric Measurements and Lifestyle Characteristics of Individuals with Non-alcoholic Fatty Liver Disease.

Background Non-alcoholic fatty liver disease (NAFLD) is a common liver disorder caused by the deposition of lipids and fats in the hepatocytes, in individuals who consume little or no alcohol, which eventually progresses to cirrhosis and carcinoma. Apart from the known risk factors like obesity, metabolic syndrome (MS), and lack of physical activity (PA), diet also plays a major role in the development of NAFLD. A high body mass index (BMI) and waist circumference (WC) have positive associations with NAFLD. The aim of this study was to find the prevalence of risk factors of hepatic steatosis in NAFLD population and to raise public awareness about the condition. Method We conducted a cross-sectional study from October to December 2019 with a sample size of 98 subjects determined by using a confidence interval (CI) of 99.9%. Patients presenting to Essa Laboratory, Karachi for abdominal ultrasound (US) were scanned for fatty changes in the liver, after obtaining consent, and were then assessed for risk factors by administering a 20-item questionnaire along with registering their BMI and WC measurement. The collected data was analyzed using the Statistical Package for Social Sciences (SPSS), version 22 (IBM, Armonk, NY). The independent sample t-test was applied for the exploration of variables and a p-value <0.05 was considered significant. Result Our study included 96 participants, of which 49 (51%) were male and 47 (49%) female. Mean BMI in females was slightly greater (30.58) than in males (27.98), whereas WC (in inches) was almost equal in males (40.796) and females (40.383). Among the people that had any comorbidities (n = 60, 62.5%), hypertension (HTN) was the most common one (n = 37, 38.5%) followed by diabetes mellitus (DM) type 2 (n = 26, 27.1%). A significant majority (n = 63, 65.5%) never consumed any fruits or vegetables in their meal nor did they perform any sort of physical exercise (n = 46, 47.9%). Conclusion Obesity (high BMI), lack of PA, lower consumption of fruits and vegetables along with a carbohydrate- and fat-rich diet play a vital role in the development of hepatic steatosis. Moreover, HTN and DM, as components of MS, exhibit a significant association with NAFLD. Screening and counseling sessions should be considered for individuals with these anthropometric measurements and lifestyle characteristics.

Assessment of Knowledge About the Risk Factors of Chronic Liver Disease in Patients Admitted in Civil Hospital Karachi.

Background Chronic liver disease (CLD) encompasses a series of single or multifactorial insults to the liver, most common of which are hepatitis, alcohol abuse, and non-alcoholic liver disease. CLD represents a major public health problem worldwide as well as in Pakistan. Unfortunately, studies evaluating the awareness of its risk factors among people are quite scarce. The purpose of this study was to assess the knowledge about risk factors of CLD in patients admitted to Dr. Ruth K M Pfau, Civil Hospital Karachi (CHK). Methods This quantitative cross-sectional study was conducted at CHK, among 368 patients admitted to CHK, during the period from February 2018 to September 2018. Frequencies and percentages were evaluated for categorical variables using Statistical Package for Social Sciences (SPSS), version 22 (IBM Corp., Armonk, NY). Chi-square test was applied to determine if there was any significant association between the variables. A p-value of <0.05 was considered significant. Results A scoring scale was developed to assess the level of knowledge. We found that only 32% of our study population had good knowledge about the risk factors of CLD while majority of them (68%) had poor knowledge. Regarding individual risk factors, >60% patients were aware that obesity, high fat intake, prolonged use of drugs, use of alcohol and hepatitis B and C are risk factors of CLD, while most of them did not know diabetes to be a risk factor as well. 51.4% patients thought that hepatitis B and C could not be transmitted via sexual contact and from mother to her baby. There was a positive association between education level and awareness about the risk factors of CLD (p = 0.006). Conclusion Future interventions to increase public awareness about CLD should promptly be taken. The lack of knowledge about this disease is the main cause of its rapid increment and the reason why it is so prevalent in our part of the world especially Pakistan. More studies and nationwide awareness programs are needed to control its spread.

Cavernous Transformation of Portal Vein in the Setting of Protein C and Anti-thrombin III Deficiency.

Cavernous transformation of the portal vein (CTPV), also known as portal cavernoma, is a sequelae of thrombosis in the portal vein causing its occlusion and portal hypertension. The etiology, however, remains unknown. Gastroesophageal variceal bleeding, splenomegaly, portosystemic collaterals, and ultimate hematologic abnormalities are among the prominent clinical features. Among the causes, predisposing an individual to CTPV is natural anticoagulant protein C and antithrombin III deficiencies. Determination of the etiology of CTPV may also give a direction toward the management plan to not only relieve the patient of the already developed complications but also to treat the primary cause of the pathology  We discuss a case of a nine-year-old male child diagnosed as CTPV secondary to protein C and antithrombin III deficiency who was treated symptomatically for anemia and varices and was referred for transjugular intrahepatic portosystemic shunt (TIPS).

Acute Myocardial Infarction as an Initial Presentation of Protein C and Protein S Deficiency Followed by Dilated Cardiomyopathy in a Young Male.

Protein C and protein S are vitamin K dependent anti-coagulant proteins required for the inhibition of activated protein V and VIII. In an inherited thrombophilia, hypercoagulability caused by the deficiency of protein C and protein S predisposes an individual to increased risk of thromboembolism (TE) that could herald as a venous thromboemboilsm (VTE) in the leg, pulmonary embolism (PE), stroke, or Budd-Chiari syndrome. However, very rarely does inherited thrombophilia cause coronary artery thrombosis leading to the development of myocardial infarction (MI). We report a case of a young male with combined protein C and protein S deficiency who presented with acute MI, worsened ventricular systolic function, and progressive declination of ejection fraction (EF) secondary to dilated cardiomyopathy (DCM).

Assessment and Improvement of Quality of Life in Patients Undergoing Treatment for Head and Neck Cancer.

INTRODUCTION: We compared the pre and post-treatment quality of life in head and neck cancer (HNC) patients and identified factors that could improve the quality of life in such patients.   Methods: The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) questionnaire was administered to 84 patients' pre and post-treatment. Patients who had non-metastatic, measurable, and untreated HNCs were invited, provided that their age was below 80 years. We did not discriminate based on treatment modality, stage of cancer, or co-morbidities. Patients who were mentally incapacitated, with secondary or recurrent HNC, distant metastasis, skin cancer, congenital anomaly of the head and neck, chronic illness, or any previous or current psychiatric illness were excluded from the study. A high mean score on the functional scale and a low score on symptom scale signify a better quality of life. We used the dependent t-test to compare pre and post-treatment scores. RESULTS: We found no statistically significant differences in any variables, except the four symptom scales of diarrhoea, constipation, nausea/vomiting, and financial difficulty. All of these variables had increased mean scores with p values of < 0.001. Also, we found no statistical significance (p = 0.250) when comparing the pre-treatment (59.4 ± 18.3) and post-treatment (61.2 ± 16.2) scores for the global health status. CONCLUSION: We found no improvement in the quality of life in HNC patients despite intervention. In fact, diarrhoea, constipation, nausea/vomiting, and financial difficulty of these patients worsened post-treatment.
