The Parasitism and Tumors Carcinogenesis: A Review Subject.

BACKGROUND: Multi-factorial reasons are an induction to cause cancer. Different infections and infestations with viruses, bacteria, and parasites have been detected for many years to be related to human carcinogenesis. PURPOSE: The study aimed to review all ideas of tumor carcinogenesis and its associations with parasitic infections and infestations. METHODS: We reviewed several articles (published and imprinted) by selecting, extracting, and synthesizing data about the relationship between cancers and parasites. RESULTS: Several helminths infections as schistosomiasis, are highly carcinogenic agents for bladder cancer, whereas trypanosomiasis has a bi-model role in cancer development. Leishmaniasis may be a cause of hepatocarcinoma, skin cancer, and lymphomas. In addition, malaria appears to be causative in the carcinogenesis of some cancers; as Burkitt lymphoma. Also, data from previous studies suggested that Strongyloides stercoralis may be a relevant co-factor in lymphomas. CONCLUSION: There are different mechanisms of parasitic infection to be enhancing in carcinogenesis of cancer in human.

Bilateral uveitis in silent ulcerative colitis: case report

Silent or subclinical inflammatory bowel diseases (IBD) is a relatively new term that has been used to describe individuals with asymptomatic active mucosal bowel inflammation, often unaware of their disease due to either the lack of or mild inflammatory symptoms. These patients are at risk for gastrointestinal and extra-gastrointestinal manifestations, with more advanced complications. In this article we intend to describe a case report of a patient with chronic history of many organ involvements including ocular, skin, and musculoskeletal, which was later placed under the umbrella of silent ulcerative colitis.

Pleural effusion in a patient with COVID-19 pneumonia and lung cancer: A case report.

Coronavirus disease is a global infection presenting with a variety of clinical features, both pulmonary and extrapulmonary symptoms. Its diagnosis depend on clinical symptoms, laboratory tests, and the typical CT chest scan findings. In this report, a 72-year-old patient (known to have lung cancer) present with pleural effusion as possible sequel of COVID-19 pneumonia. Pleural effusion may present as a complication in a patient with coronavirus disease, but there is poor evidence to this claim in the medical literature.

Alteración de las vitaminas en pacientes con cáncer: un estudio comparativo prospectivo / Vitamins disturbance in cancerous patients: A prospective comparison study

Cancers are a complex diseases that involve abnormal cell growth pattern and it is the leading cause of morbidity and mortality worldwide. The chemotherapy is one of the most common treatments for cancer. Cancer cause malnutrition and deficiencies of vitamins, in addition chemotherapy causes those deficiencies by induced anorexia, stomatitis, and alimentary tract disturbances. The study aims to determined and assessed the levels of serum vitamins (A, B12, B6, B9, E, D, and K) before and after chemotherapy administration. A prospective study carried out on newly diagnosed cancerous patients whom receiving chemotherapy. Fifty patients enrolling and recruited. Follow up will be recorded after the first, third, and sixth cycles of chemotherapy. The panel used for evaluation of vitamins concentration included the following six kits: Human Vitamin AV, E, VB6, B12, VD3 DIY, VK and FOLR3 ELISA kits. 38 females and 12 males included, with mean age was 48.35±15.28 years. The mostly distributed age group was belong to fifth decades. The mean body mass index (BMI) was 33.12±5.51 m2 /Kg. The majority of the sample treated were breast cancers females about 26(52%). Regarding chemotherapy regimens, the AC+Taxen protocol was mostly used. The mean level of vitamin A found to be declined to the half from (69.23±24.66 µg/dL) at C0 to (35.73±18.89 µg/dL) at C6. Normal mean value of vitamin B12 level was presented in the most of patients pre- and post- chemotherapy. Vitamin B6 concentrations in the most of patients risen by double post-chemotherapy. Vitamin D concentration not changed in pre- and post- chemotherapy. We observed a statistically significant differences among vitamin E concentration pre- and post- chemotherapy (ANOVA=3.213, P=0.033). In this study, most of patients pre-chemotherapy period had normal folate level, whereas it to decreased from (6.23±3.12 ng/mL) to reached (3.33±2.72 ng/mL) after anti-cancer, with strong statistically significant differences (ANOVA=6.56, P=0.012). In addition, vitamin K concentration was unchanged throughout chemotherapy cycles. Many factors in cancerous participants lead to vitamins deficiencies. Several vitamins remained within normal concentration throughout anti-cancer course might be due to vitamins supplement taken by persons during their regimens. Almost always vitamins concentration dropped during cycles, but still within normal value, except vitamin E, which was deficient in last cycle of chemotherapy. Vitamins replacement are mandatory for substitution dropping level because off those are essential for many body processes and regulation.

Spontaneous pneumothorax as a complication in COVID-19 male patient: A case report.

Coronavirus disease 2019 infection may be later complicated with pneumothorax after primarily symptoms. We must be aware about pneumothorax, which may be increased in cases of COVID-19.

Granulomatosis (Wegener's granulomatosis) with polyangiitis presented as pulmonary manifestation: a case report.

Pulmonary vasculitis can be the manifestation of several systemic illnesses such as primary systemic vasculitis, collagen vascular diseases, and systemic diseases associated with autoantibodies. It may be associated with granulomatous, eosinophilic, lymphoplasmacytic and neutrophilic inflammatory diseases. In this case report, we describe a 22-year-old female presented with intermittent fever, sweating and shivering, haemoptysis, sore throat, shortness of breath, fatigue, loss of appetite, nausea, non-projectile vomiting, dizziness, and dark coloured urine. The diagnosis of granulomatosis with polyangiitis was made utilizing biochemical and radiological tests. Several pharmacological therapies were tried including rituximab. The patient made a good recovery and was discharged home after 12 days of hospitalization. The knowledge of the main radiographic and computed tomography (CT) scan findings, in association with clinical and laboratory data, often enables non-invasive diagnosis of pulmonary vasculitis.

Epidemiological and prognostic single center study of anal carcinoma / Estudo epidemiológico e prognóstico em um único centro de carcinoma anal

Abstract Background: Anorectal carcinoma includes the anal margin, the anal canal, and the lower rectum. The incidences of anal tumors represent 1.4 % of all gastrointestinal tumors. Patients and methods: Our study is retrospective and was conducted at Baghdad Medical City. Patient's data were collected from the medical records through a predesigned sheet that included the following information: demographic data, medical history, past-history, presenting symptoms, pathological data, and treatment details. Results: The median age was 49 years. As regard tumor extension, 85.71 % of patients had anal disease, while anorectal cancer was encountered in 14.28 % of cases only. Male to female ratio was 1:3. Most of cases were SCC 78.57 %. Only 11 patients (39.28 %) were diagnosed as Stage I, whereas 12 patients (42.85 %) had Stage II-III disease. Moderate differentiated tumors are the most common. The tumor mass located between 5-10 cm das a distance from anal verge in 12 (42.85 %) of patients. We found 6 (21.42 %) patients with positive virology tests with no specificity detected. APR was the mainstay for treatment of stage I disease. Neoadjuvant treatment followed by TME resection was the treatment found in locally advanced tumors. The mean Overall Survival (OS) for patients received neoadjuvant CRT in the study was 43.5 months, while, the mean OS was 45.73 months in the adjuvant setting. Univariate analysis for OS according to prognostic factors revealed that sites of cancer, grades and histopathology were significant independent prognostic factors for OS in this study. The anal canal tumor was associated with shorter OS (33.25) months in comparison to the anorectal cancer (OS = 47.22 months). Based on tumor grade, well and moderate differentiation have better OS (60.21 months) while, poorly grade was associated with shorter OS (43.07 months). On the concern of SCC, it was associated with shorter OS (37 months) in comparison to higher survival in patients with adenocarcinoma (46.13 months). Conclusion: Anal canal cancer has poorer prognosis than anorectal. The early-stage has a better OS that needs more effort for early diagnosis and treatment.

Resumo Antecedentes: O carcinoma anorretal inclui a margem anal, o canal anal e o reto inferior. A incidência de tumores anais representa 1.4 % de todos os tumores gastrointestinais. Pacientes e métodos: Nosso estudo é retrospectivo e foi realizado no Baghdad Medical City. Os dados do paciente foram coletados dos registros médicos por meio de uma folha pré-projetada que incluía as seguintes informações: dados demográficos, histórico médico, histórico anterior, sintomas de apresentação, dados patológicos e detalhes do tratamento. Resultados: A idade média foi de 49 anos. Quanto à extensão do tumor; 85,71 % dos pacientes apresentavam doença anal, enquanto o câncer anorretal foi encontrado em 14,28 % dos casos. A proporção homem/mulher foi de 1:3. A maioria dos casos foi de CEC 78,57 %. Apenas 11 pacientes (39,28 %) foram diagnosticados como Estágio I, enquanto 12 pacientes (42,85 %) apresentavam doença em Estágio II?III. Tumores diferenciados moderados são os mais comuns. A massa tumoral localizada entre 5-10 cm das distâncias da margem anal em 12 (42,85 %) dos pacientes. Foram encontrados 6 (21,42 % pacientes com testes virológicos positivos sem especificidade detectada. A TAEG foi a base para o tratamento da doença em Estágio I. O tratamento neoadjuvante seguido pela ressecção do TME foi o tratamento encontrado em tumores localmente avançados. A sobrevida global média OS dos pacientes que receberam TRC neoadjuvante no estudo foi de 43,5 meses, enquanto a OS média foi de 45,73 meses no cenário adjuvante. A análise univariada para OS de acordo com fatores prognósticos revelou que locais de câncer, notas e histopatologia foram fatores prognósticos independentes significativos para OS neste estudo. O tumor do canal anal foi associado a SG mais curtos 33,25 meses em comparação ao câncer anorretal OS = 47,22 meses. Com base no grau do tumor, a diferenciação boa e moderada apresenta melhor OS 60,21 meses, enquanto o grau ruim foi associado a um OS mais curto 43,07 meses. No que diz respeito ao CEC, este foi associado a uma OS mais curta 37 meses em comparação à maior sobrevida em pacientes com adenocarcinoma 46,13 meses. Conclusão: O câncer de canal anal tem pior prognóstico que o anorretal. O estágio inicial tem um sistema operacional melhor que precisa de mais esforço para diagnóstico e tratamento precoces.

Patrón de agregados de cáncer entre familias en Irak / Cancer Aggregates Pattern among Families in Iraq

Breast cancer is first ranking malignancies in Iraq. Family history of cancer is an important factor for cancer occurrence and development in next generation. The study aimed to determine the validity of family history of cancer by population-based and clinic-based family registries, evaluate the concurrence of cancer affected by family history in their first-, and second-degree relatives. An observational studies of total 62 relatives membered of 44 Iraqi breast cancer families were included. We conducted study at period between December 2018 and June 2019. Data collected according NCCN Genetic Testing Criteria for Hereditary Breast and Ovarian Cancer Syndrome. Risk ratio (RR) used to evaluating predilection of family cancer risk. We addressed forty-four Iraqi breast cancer families who have sixty-two members with cancer. The age mean±SD was 51.8±12.6, and median=48.5 years. Meanwhile the age mean±SD= 51.6±11.9 years for relatives. M:F ratio equal to 3:1. Sister, mother and aunt/uncle were most common relative affected. Breast cancer represented the most frequent types found in 46.7% of patients. Mothers (RR=1.313), and/or sisters (RR=1.6), lead to increased risk of cancer development in other family members or next generation. The first degree relatives recorded more than the second degree relatives. This is the first study conducting in Iraq dealing with cancer risk at the level of families. The age of patients didn't differ from age at diagnosis, concluding there is no active screening programs run through Iraqi families. Sister, mother and aunt/uncle are the most relatives affect. The 1st-degree relatives more frequent than the 2nd-degree. Breast cancer represented the most common types found members studied. Mothers and sisters have highly risk ratio for developing family cancer among other individuals.

Rectal cancer and chemoradiation in Iraq: systematic review and meta-analysis / Câncer retal e quimiorradioterapia no Iraque: revisão sistemática e metanálise

Abstract Background: Rectal cancer is one of the most common malignant tumors of gastrointestinal tract. Combining chemotherapy with radiotherapy has a sound effect on its management. Objectives: Assessment the patterns of characterizations of rectal cancer. Evaluation of the efficacy, and long-term survival of pre-/ postoperative chemoradiation. Collecting all eligible evidence articles and summarize the results. Methods: By this systematic review and meta-analysis study, we include data of chemoradiation of rectal cancer articles from 2015 until 2019. The research was carried out at Baghdad Medical City oncology centers. Accordance with the PRISMA guidelines, and the Newcastle-Ottawa Scale used. Results: Starting with gender distribution as M:F ratio of 0.94:1.06. Regarding the age, recorded mean ± SD of 48.7 ± 14.2 years. Rectosigmoid represented the most common site as 50(49.5%), and adenocarcinoma was common histopathology as 76(75.2%) of patients, with localized stage in 50(49.5%). The moderate differentiation was most grade as 65(64.4%). The distant from anal verge mostly seen was 5-10 cm in 59(58.4%). The pulmonary was commonest site of metastasis in 11(10.9%). Most patients undergo APR operation, which has done in 41(40.6%). Adjuvant chemoradiation received by 40(39.6%) patients, whereas neoadjuvant chemoradiation gave to 25 patients. A total of 2609 articles from 12 databases met our search strategies. The highest Newcastle-Ottawa score (8) demonstrated in three studies, and median score (7) calculated in five studies. Conclusions: The incidence belonged to 5th and 6th decade of life. Rectosigmoid represented the most common site. Mostly, the 5-10 cm distant of tumor from anal verge was common finding. The pulmonary was most site of metastasis. We concluded the formulation of a novel point that survival benefit found in many pre or postoperative chemoradiation trials in rectal cancer.

No presente estudo, quimiorradioterapia pré- ou pós-operatória estava relacionada a uma maior sobrevida em casos de câncer retal.

Intra-articular osteoid osteoma of tempromandibular joint: A case report.

INTRODUCTION: An osteoid osteoma is a benign bone neoplasm with limited growth potential, characterized by significant nocturnal pain that usually responds to non-steroidal anti-inflammatory drugs (NSAIDs). The tumor may occur in any part of the skeleton, most commonly in the lower extremities and vertebrae. PRESENTATION OF CASE: A 46-year-old female was diagnosed with a rare case of an intra-articular variant of osteoid osteoma, involving the articular eminence and glenoid fossa of the temporo-mandibular joint (TMJ). DISCUSSION: The tumor presented as a painful progressive swelling in the right pre-auricular area that had lasted for more than 2 years and which had been previously treated as a TMJ disorder. Computed tomography revealed a well-defined heterogeneous nidus involving the articular eminence of the TMJ. Surgical excision was performed and histological examination confirmed the diagnosis. In this article, in addition to describing the case, all cases of osteoid osteoma of the jaws and TMJ reported in the English-language literature are reviewed. CONCLUSION: Osteoid osteoma involving the TMJ is a rare presentation and may exhibit ambiguous symptoms, which could lead to misdiagnosis and delayed treatment.
