Postpartum incidental solid pseudopapillary tumor of the pancreas: case report

Solid pseudopapillary tumors of the pancreas are usually described as rare lesionswith low malignant potential and unpredictable behavior. The prognosis may be favorableeven with local or distant dissemination. Despite the steady increase of cases diagnosed,the pathogenesis of this neoplasm remains unclear. We present a case of an incidentaltumor discovered because of an acute abdomen in a postpartum woman without previousevidence of a tumor during the pregnancy.

Disseminated nocardiosis due to Nocardia farcinica: diagnosis by thyroid abscess culture

Paciente previamente hígido, homem de 75 anos, branco, dentista, apresentou história de seis meses de dor lombar, fez uso crônico de corticoterapia e teve diagnóstico de infecção por Nocardia farcinica através do aspirado de abscesso da tireóide e seis hemocultivos positivos. Apesar do tratamento com a combinação de sulfametoxazol/trimetoprim, o paciente não respondeu indo a óbito dois dias após. A necropsia revelou nocardiose disseminada, envolvendo ambos os pulmões, empiema bilateral, coração, tireóide, rins, cérebro, ossos, e tecidos moles lombossacrais, com destruição da L2-L4.

Disseminated nocardiosis due to Nocardia farcinica: diagnosis by thyroid abscess culture.

A previously healthy 75-year-old white male dentist presented with a 6-month history of low-back pain treated with chronic steroid therapy had a Nocardia farcinica infection diagnosed by aspirate of thyroid abscess and six blood cultures. Despite the treatment with parenteral combination of trimethoprim/sulfamethoxazole, the patient failed to respond and died after two days of therapy. Autopsy revealed disseminated nocardiosis, involving lungs with pleural purulent exudate in both sides, heart, thyroid, kidneys, brain, bones, and lumbosacral soft tissue with destruction of L2-L4.

Radiofrequency ablation in the treatment of pelvic recurrence of rectal cancer.

The aim was to assess the response to the treatment using thermal radiofrequency ablation in patients with pelvic recurrent rectal cancer. The location of the lesions as well as the placement of the percutaneous probe were guided by computed tomography. All ablations were performed with a RITA Medical Systems Starburst XL (nine-array, 5-cm) thermal ablation catheter and the Model 1500 generator (RITA Medical Systems, Inc.). The radiofrequency ablation treatment was performed in two patients with pelvic recurrent rectal cancer with poor response to chemoradiotherapy with no indication of new surgical treatment and suffering strong pain in the sacrum area. The serum carcinoembryonic antigen had a sharp reduction in a sixty-day period. The post-procedure tomography analysis showed the center of the tumor with necrosis and a ring of edema around it. Both patients had no complaints about the procedure, and they needed to take mild analgesics only on the first day right after the procedure for pain. In the follow-up one patient developed an abscess and needed to be readmitted but without recurrent pelvic pain. An effective response was shown by tumor necrosis and total relief of pain of the sacrum area.

Análise tomográfica da anteversäo acetabular / CT scan analysis of acetabular anteversion

O ângulo de anteversäo acetabular (AVA) foi determinado através de tomografia computadorizada em 34 pacientes adultos que apresentavam quadris normais no presente estudo. Foi feita uma seleçäo cuidadosa do corte tomográgico através do centro do acetábulo com o objetivo de se obter valores consistentes da anteversäo acetabular. A média da anteversäo acetabular foi de 20,44§. Näo houve diferença significante na medida do ângulo de anteversäo acetabular entre os lados direito e esquerdo. O AVA näo se altera durante a vida adulta. É feita uma correlaçäo clínico-prática entre o AVA e a artroplastia total do quadril.
