Torsions of the spermatic cord occurring from the intrauterine period to the end of the first year of life are termed perinatal. These are divided into prenatal and postnatal torsions, depending on their occurrence in the intrauterine or postuterine period. From January 1984 to January 1996, 6 cases were identified at our institution, involving 4 prenatal and 2 postnatal extravaginal torsions of the spermatic cord. These cases are reviewed with regard to optimal therapeutic approaches for the treatment of both the affected gonad as well as the contralateral one, and whether the event occurred prenatally or postnatally. The authors also propose several clinical indications useful for obstetricians, pediatricians, urologists and nurses. 相似文献

Retroperitoneal lymphangioleiomyomatosis: CT appearance 总被引:1,自引:0,他引:1
Lymphangioleiomyomatosis is a rare disease involving the lung, lymphatic trunk and lymph nodes. Sometimes it appears in the
retroperitoneum with or without subsequent development in the lungs. We present a 52-year-old woman with retroperitoneal location
of the disease. We discuss the abdominal CT appearance, the cytologic and immunophenotypic features and a preoperative differential
diagnosis is attempted.

Throughout the past six decades, our understanding of cancer of the prostate and the treatment of the disease using endocrine therapy has been centred on the classical investigations of Charles Huggins, which established that tumor tissue of the prostate as well as the normal tissue of the gland retained some degree of androgen dependence. Attention must now be focussed on the 20-40% of patients who are resistant to endocrine therapy. These patients are non-responders to conventional endocrine treatment after 3 to 6 months, quickly progress and die of the disease. In terms of molecular endocrinology related to the progressive stage of the disease, it would be expected that the cancer is being driven by the uncontrolled action of growth factors. Experiments combining oligonucleotide treatment with cytotoxic chemotherapeutic agents demonstrated a marked increase in the sensitivity of the prostate cancer cells. Results indicate that despite the presence of Bcl-x pre-mRNA in a number of cell types, the effects of modification of its splicing by antisense oligonucleotides vary depending on the expression profile of the treated cells. The transition from androgen-dependent to androgen non-dependent prostate cancer is accompanied by a number of molecular genetic changes, including overexpression of the Bcl-2 gene. Overexpression of Bcl-2 protein decreases the pro-apoptotic response to such cellular insults as irradiation, chemotherapy, and androgen withdrawal. The future looks promising and this kind of treatment offers a novel approach to alternative therapeutic options for advanced prostate cancer. Although numerous chemotherapeutic regimens have been evaluated for patients with hormone-refractory prostate cancer, none has improved survival. 相似文献

Objective
The ATP-binding cassette transporter A1 (ABCA1) is essential protein involved in lipid metabolism. The present study was undertaken to detect the possible association of polymorphisms in the ABCA1 gene [rs2230806 (R219K) and rs2230808 (R1587K)] and lipid profile in Greek young nurses. 相似文献5.

We present a 57-year-old man with Zollinger-Ellison syndrome who had undergone total gastrectomy 12 years previously. At that time, a cystic mass in the left lobe of the liver was palpated but was not removed. The patient currently had high serum gastrin levels. Abdominal ultrasound, CT and MR images showed a well defined liver mass with solid and cystic components. The lesion was resected and a primary hepatic carcinoid tumour was diagnosed. Post-operatively, serum gastrin levels were normal. A primary liver carcinoid may appear as multicystic liver mass with solid components. Careful exclusion of a primary tumour elsewhere is required to establish the diagnosis of this rare entity. 相似文献

Schwannomatosis is a genetic disorder characterized by the occurrence of multiple peripheral schwannomas. Segmental schwannomatosis is diagnosed when schwannomas are restricted to 1 extremity and is thought to be caused by genetic mosaicism. We studied 5 patients with segmental schwannomatosis through microstructural magnetic resonance neurography and mutation analysis of NF2, SMARCB1, and LZTR1. In 4 of 5 patients, subtle fascicular nerve lesions were detected in clinically unaffected extremities. Two patients exhibited LZTR1 germline mutations. This appears contrary to a simple concept of genetic mosaicism and suggests more complex and heterogeneous mechanisms underlying the phenotype of segmental schwannomatosis than previously thought.

Hepatoblastoma, a malignant tumor which arises occasionally in older children but very rarely in adults, exhibits divergent differentiation with embryonal cells, fetal hepatocytes and immature elements. This report describes an embryonal type hepatoblastoma with neuroendocrine differentiation in a 16‐year‐old patient, which was diagnosed postoperatively. Clinical and radiologic work‐up failed to reveal a primary gastrointestinal malignancy and no primary lesions were detected in any other organ. This feature of hepatoblastoma is considered to be a multidirectional differentiation of the small epithelial or stem cells of the liver. At 2‐year follow up, the patient remains symptom‐free, with normal laboratory and diagnostic imaging studies, and no recurrent or metastatic disease identified. 相似文献

The purpose of this study was to compare the activity and toxicity of an irinotecan (CPT-11), leucovorin (LV) and 5-fluorouracil (5FU) combination with a standard regimen of 5FU and LV, in patients with advanced colorectal carcinoma. One hundred and sixty patients were randomized; 80 patients (group A) received LV 20 mg/m(2) bolus i.v. and 5FU 425 mg/m(2) bolus i.v. on days 1-5, every 28 days; 80 patients (group B) received CPT-11 80 mg/m(2) (30-90 min i.v. infusion), followed by LV 20 mg/m(2) bolus i.v. and 5FU 425 mg/m(2) bolus i.v. on days 1, 8, 15, 22, 29, and 36, every 8 weeks. The overall response rate was 30% and 47.5% in groups A and B respectively. Progression-free survival was significantly higher in the triple-drug combination arm (median 7.5 vs. 4.5 months; p= 0. 0335). However, overall survival did not differ significantly between the two arms (15 months vs. 14 months for the groups B and A respectively; p=0.3531). The main grade 3 adverse events were diarrhea (19%, in group A vs. 35% in group B; p=0.032) and mucositis (2% vs. 14%; p=0.017). The regimen containing irinotecan showed activity in advanced colorectal cancer. The overall safety data confirm this combination as a well-tolerated treatment. 相似文献
