Recurring hydatide cyst in abdominal cavity. A case report.

Hydatid cyst (hydatidosis or echinococcosis) is an endemic zoonosis caused by ingestion of Echinococcus eggs. This disease is localized to the liver, but can be found elsewhere. It may be asymptomatic or present with compression discomfort or anaphylactic shock due to cyst rupture. The disease can recur. The diagnosis is made by the symptoms and imaging findings. Serological tests are sometimes done. The diagnosis is confirmed with direct observation of the parasite. Treatment is a combination of anthelmintic with minimally invasive or surgical drainage. This report is from a patient with recurrent hydatid cysts in the abdomen.

El quiste hidatídico (hidatidosis o equinococosis) es una zoonosis endémica causada por la ingesta de huevos de Echinococcus. Esta enfermedad se localiza en el hígado, pero también puede encontrarse en otros sitios. Puede ser asintomática o presentarse con molestias por compresión o choque anafiláctico por rotura del quiste. Puede tener recurrencias. El diagnóstico se realiza por los síntomas y los hallazgos en imagenología. En ocasiones se realizan pruebas serológicas. El diagnóstico se confirma con la observación directa del parásito. El tratamiento es una combinación de antihelmíntico con drenaje mínimamente invasivo o quirúrgico. Se reporta el caso de una paciente con quistes hidatídicos recurrentes en el abdomen.

Epidemiology of end-stage renal failure among twins and diagnosis, management, and current outcomes of kidney transplantation between identical twins.

The aim of the study is to provide a comprehensive overview of identical twin kidney transplantation in the modern era. We provide epidemiologic trends in the US twin population from 1959 to 2000, current methods to identify zygosity, outcomes for identical twin transplants, and a comprehensive management strategy for identical twin kidney transplantation. By 2019, we project that 433 010 dizygotic and monozygotic twins will be alive and at risk for developing ESRF. Monozygosity between a donor-recipient pair can be confirmed by concordance in sex, blood type, and HLA antigen match with precision testing using 13/17 Short Tandem Repeat sequencing to a likelihood of nearly 100%. Among identical twin transplants from 2001 to 2017, excellent patient and kidney graft survival rates were noted. Approximately 50% of kidney transplant recipients of identical twins transplant did not receive maintenance immunosuppression, and no differences in graft survival were noted among patients with and without immunosuppression at 6 and 12 months (P = .8 and .7). Patients with glomerulonephritis as the cause of ESRF had lower graft survival (P = .06) suggesting that recurrent glomerulonephritis as a likely cause of graft loss among these recipients.

Lupus Nephritis and Kidney Transplantation: Where Are We Today?

Lupus nephritis (LN) is the cause of end-stage kidney disease (ESKD) for 1.9% of the ESKD population in the United States. Although the incidence rates of ESKD from LN stopped rising in recent years, racial disparities in waiting time, pre-emptive kidney transplant, and transplant outcomes still exist. Patients with LN who progress to ESKD tend to be female, of African ancestry, and young. Kidney transplantation is safe in this population and associated with a substantial survival benefit, primarily due to reduced deaths from cardiovascular disease and infection. Transplant outcomes for patients with ESKD due to LN are similar to those without LN.

Influence of chronic lymphocytic thyroiditis on the risk of persistent and recurrent disease in patients with papillary thyroid carcinoma and elevated antithyroglobulin antibodies after initial therapy / Influência da tireoidite linfocítica crônica sobre o risco de doença persistente e recorrente em pacientes com carcinoma papilífero de tireoide e anticorpos antitireoglobulina elevados após a terapia inicial

Abstract Introduction In patients with papillary thyroid carcinoma who have negative serum thyroglobulin after initial therapy, the risk of structural disease is higher among those with elevated antithyroglobulin antibodies compared to patients without antithyroglobulin antibodies. Other studies suggest that the presence of chronic lymphocytic thyroiditis is associated with a lower risk of persistence/recurrence of papillary thyroid carcinoma. Objective This prospective study evaluated the influence of chronic lymphocytic thyroiditis on the risk of persistence and recurrence of papillary thyroid carcinoma in patients with negative thyroglobulin but elevated antithyroglobulin antibodies after initial therapy. Methods This was a prospective study. Patients with clinical examination showing no anomalies, basal Tg < 1 ng/mL, and elevated antithyroglobulin antibodies 8-12 months after ablation were selected. The patients were divided into two groups: Group A, with chronic lymphocytic thyroiditis on histology; Group B, without histological chronic lymphocytic thyroiditis. Results The time of follow-up ranged from 60 to 140 months. Persistent disease was detected in 3 patients of Group A (6.6%) and in 6 of Group B (8.8%) (p = 1.0). During follow-up, recurrences were diagnosed in 2 patients of Group A (4.7%) and in 5 of Group B (8%) (p = 0.7). Considering both persistent and recurrent disease, structural disease was detected in 5 patients of Group A (11.1%) and in 11 of Group B (16.1%) (p = 0.58). There was no case of death related to the disease. Conclusion Our results do not support the hypothesis that chronic lymphocytic thyroiditis is associated with a lower risk of persistent or recurrent disease, at least in patients with persistently elevated antithyroglobulin antibodies after initial therapy for papillary thyroid carcinoma.

Resumo Introdução Em pacientes com carcinoma papilífero de tireoide e com tireoglobulina sérica negativa após a terapia inicial, o risco de doença estrutural é maior entre aqueles com anticorpos antitireoglobulina elevados em comparação com pacientes sem anticorpos antitireoglobulina. Outros estudos sugerem que a presença de tireoidite linfocítica crônica está associada a um menor risco de persistência/recorrência do carcinoma papilífero de teireoide. Objetivo Este estudo prospectivo avaliou a influência da tireoidite linfocítica crônica sobre o risco de persistência e recorrência do carcinoma papilífero de tireoide em pacientes com tireoglobulina negativa, mas com anticorpos antitireoglobulinas elevados após a terapia inicial. Método Esse foi um estudo prospectivo, no qual foram selecionados pacientes com exame clínico sem anomalias; tireoglobulina basal < 1 ng/mL e anticorpos antitireoglobulina elevados 8-12 meses após ablação. Os pacientes foram divididos em dois grupos: Grupo A, com tireoidite linfocítica crônica no exame histológico; Grupo B, histologicamente sem tireoidite linfocítica crônica. Resultados O tempo de seguimento variou de 60 a 140 meses. Doença persistente foi detectada em 3 pacientes do Grupo A (6,6%) e em 6 do Grupo B (8,8%) (p = 1,0). Durante o seguimento, as recidivas foram diagnosticadas em 2 pacientes do Grupo A (4,7%) e em 5 do Grupo B (8%) (p = 0,7). Considerando tanto a doença persistente quanto a recorrente, doença estrutural foi detectada em 5 pacientes do Grupo A (11,1%) e em 11 do Grupo B (16,1%) (p = 0,58). Não houve nenhum caso de óbito relacionado à doença. Conclusão Nossos resultados não apoiam a hipótese de que a tireoidite linfocítica crônica esteja associada a um menor risco de doença persistente ou recorrente, pelo menos em pacientes com anticorpos antitireoglobulina persistentemente elevados após a terapia inicial do carcinoma papilífero de tireoide.

Bevacizumab for recurrent, persistent or advanced cervical cancer: reproducibility of GOG 240 study results in "real world" patients.

PURPOSE: Bevacizumab is the only therapeutic target approved for patients with persistent, recurrent or advanced cervical cancer from a phase III study that combined with chemotherapy; it proves a significant increase in overall survival. To retrospectively assess the efficacy and safety of bevacizumab as the first-line treatment in patients from usual clinical practice with recurrent/persistent or advanced cervical cancer. PATIENTS AND METHODS: Treatment consisted of cisplatin 50 mg/m2 or carboplatin AUC 5 plus paclitaxel 175 mg/m2 for 6-8 cycles and bevacizumab 15 mg/kg every 3 weeks up to progression or unacceptable toxicity. The endpoints were progression-free survival (PFS), overall survival (OS), response rates (RR) and toxicity. RESULTS: Twenty-seven patients were included from January 2014 to June 2017, with a median follow-up 10, 1 months. Eleven percent had recurrent/persistent disease and 89% had metastatic disease at diagnosis. The prior exposition to platinum was 70%. The median PFS and OS were 9, 6 and 21, 5 months, respectively. There was an increase of fistula formation (22%). All of them had pelvic and peritoneal disease at the beginning of treatment and previous treatment with chemoradiotherapy; non-incidence differences were found according to the type of platinum agent used. There were two treatment-related deaths, one from intestinal perforation and another from severe sepsis. CONCLUSION: Finally, although our study does have certain limitations, we believe that it can provide useful information and encouraging evidence that the routine use of bevacizumab as part of first-line treatment of patients with advanced cervical cancer may be associated with outcomes comparable with those obtained in GOG240 study.

SEOM Clinical Guideline in ovarian cancer (2016).

Despite remarkable advances in the knowledge of molecular biology and treatment, ovarian cancer (OC) is the first cause of death due to gynecological cancer and the fifth cause of death for cancer in women in Spain. The aim of this guideline is to summarize the current evidence and to give evidence-based recommendations for clinical practice.

Persistent and recurrent disease in patients with papillary thyroid carcinoma with clinically apparent (cN1), but not extensive, lymph node involvement and without other factors for poor prognosis

Objective Lymph node metastases (LNM) are frequent in patients with papillary thyroid cancer (PTC). The risk of persistent disease (PD) and tumor recurrence (TR) is increased when factors for poor prognosis other than LNM exist, when LNM are numerous, large, detected by preoperative ultrasonography (US), or exhibit extranodal extension. This study evaluated the risk of PD and TR in patients with LNM not exhibiting these characteristics.Subjects and methods Eighty-six patients with 5 or fewer LNM detected during intraoperative inspection, but not by preoperative US, who had no other factors for poor prognosis [tumors > 4 cm, extensive extrathyroid invasion, vascular invasion, aggressive histological subtype, distant metastases, incomplete tumor resection], were studied. All patients underwent total thyroidectomy followed by radioiodine ablation. PD was defined as metastases on initial post-therapy whole-body scans (RxWBS) or detected by imaging methods up to 12 months after ablation. TR was defined as structural disease diagnosed more than one year after ablation in patients without PD.Results PD was diagnosed in 3/86 patients (3.5%). TR was observed in 2/83 patients (2.5%) after 62 months of follow-up. There was no case of death due to the disease. A correlation was observed between pre-ablation Tg and PD or TR [1/48 (2%) with Tg ≤ 2 ng/mL versus 2/22 (9%) with Tg > 2 ≤ 10 ng/mL versus 2/7 (28.5%) with Tg ≥ 10 ng/ml)]. It is noteworthy that 38 patients had up to 3 positive LN and pre-ablation Tg ≤ 2 ng/ml, and none of them had PD or TR.Conclusions The frequency of PD and TR was low in patients with PTC with 5 or fewer LNM and without other factors for poor prognosis. Low postoperative stimulated Tg was predictive of the absence of PD and TR in these patients.
