ABSTRACT

Polycythemia vera (PV) is a chronic myeloproliferative neoplasm (CMN) characterized by the accumulation of red blood cells, granulocytes and platelets in the peripheral blood. The main complications of PV are an increased risk of thrombosis, bleeding and transformation to myelodysplasia or acute leukemia. The authors report the case of a 28-year-old man with a complaint of macroscopic hematuria, low back pain and edema of the left arm associated with elevated hemoglobin, hematocrit and lactic dehydrogenase, leukocytosis and increased renal volume. Computed tomography of the chest and abdomen with contrast showed venous ectasia in the left upper limb and thrombosis of the right renal vein with extension to the inferior vena cava. A diagnosis of PV was confirmed by the presence of the JAK2 mutation and a bone marrow biopsy that showed panmyelosis. The patient was anticoagulated and treatment for PV was started with aspirin, phlebotomy and hydroxyurea. Then, the patient was discharged for outpatient follow-up with a hematologist. The case emphasizes the importance of clinical suspicion for atypical presentation of the disease in an unusual age range and of adequate etiological investigation of thrombosis in unusual sites.

ABSTRACT

Interstitial or cornual implantation of the blastocyst is rare, accounting for 2% to 3% of ectopic pregnancies, being considered not viable. The important complications of interstitial pregnancy are uterine rupture and massive bleeding, which usually occur before 12 weeks of pregnancy. The authors report a case of a 36-year-old woman with complaints of transvaginal bleeding and abdominal pain associated with amenorrhea for seven weeks and positive beta-human chorionic gonadotropin (HCG). Transvaginal ultrasound and exploratory laparotomy were performed, confirming the diagnosis of interstitial ectopic pregnancy. The patient underwent a salpingectomy and cornual resection on the left, evolving with clinical improvement and hospital discharge.

ABSTRACT

The diagnosis of parkinsonism is established by the presence of tremor, stiffness and bradykinesia alongside with neurological examination, requiring the exclusion of secondary causes such as stroke, hydrocephalus and infectious diseases. Included in this last category, neurocysticercosis is a disease caused by Taenia solium, with a variable clinical presentation that can include epileptic seizures, hydrocephalus and rarely parkinsonism. In the reported case, the syndrome is a consequence of lesions in the nigrostriatal dopaminergic pathway caused by the implant and mass effect of the cysticercus. The authors report a case of parkinsonism in a 59-year-old woman with a previous history of neurocysticercosis who presented with hydrocephalus on magnetic resonance imaging exam. The patient was treated with pharmacological therapy and ventriculoperitoneal shunt, progressing with amelioration of the symptoms presented.
