We present a case of intrapulmonary metastasis developing 18 years after complete resection of thymoma. An 8 mm nodule in the lower lobe of the left lung was noted on chest X-ray in a 76-year-old woman who had undergone complete resection of Masaoka’s stage II thymoma 18 years earlier. Since the nodule grew to 17 mm during a 2-year follow-up, wedge resection was performed. The lesion was histologically diagnosed as an intrapulmonary metastasis from thymoma. Extremely late recurrence after complete resection of thymoma is discussed. 相似文献

We describe a 53-year-old man with herpes simplex virus (HSV) brainstem encephalitis diagnosed based by positive HSV immunoglobulin M antibodies from cerebrospinal fluid. The MRI findings of this case had three unique features. First, the lesions were symmetrical. Second, the lesions may have been associated with reactivation of HSV infection in the region of the trigeminal nerve. Third, diffusion-weighted and apparent diffusion coefficient (ADC) imaging, conducted for the first time on an HSV brainstem encephalitis case, suggested that the lesions were associated with vasogenic edema. 相似文献

PURPOSE: The purpose of this study was to test the functional and histologic fate of costochondral grafts (CG) in temporomandibular joint (TMJ) reconstruction for unilateral ankylosis in the sheep. MATERIALS AND METHODS: Five pure-bred adult Merino sheep were used. Ankylosis was induced by articular damage, disc removal, and placement of a bone graft. At 3 months, a gap arthroplasty was performed with a CG from the thirteenth rib. The sheep were sacrificed 3 months after CG reconstruction. The range of jaw movements were recorded at first operation, at lysis of ankylosis, and at sacrifice. The joints were examined radiologically, macroscopically, and histologically. RESULTS: All sheep showed a decrease in masticatory function, as shown by weight loss and decreased jaw opening, during the ankylosis period. On release, they regained weight and increased the range of jaw movement. Histologically, the joint space was filled with fibrous tissue. However, the partial spaces around the CG head were covered by fibrous tissue and/or fibrous cartilage. CONCLUSIONS: This study shows that, when CGs are used with a gap arthroplasty in a fibrous and bony ankylosed TMJ, masticatory function is restored. 相似文献

Of the patients who had had a urodynamic examination during the five year period from 1982 to 1987 in our clinic, 48 patients underwent operations for rectal cancer prior to the study. In 35 of them, the operation mode was known. If the pelvic nerve is damaged by operative modes for rectal cancer, urinary disturbances of severe kinds may occur. In spite of such disturbances, 71.4% of those who had had excision of the low anterior part and 51.9% of those with Miles' operation could be weaned from the clean intermittent self-catheterization and take up spontaneous urination. Even in patients who developed severe dysuria, if catheterized at an early stage, many of them could urinate by abdominal pressure with in several months after operation, without the aid of a catheter. This transition took place mostly within one year after operation. When a patient develops dysuria after radical surgery for rectum cancer, treatment mainly with self-catheterization is an effective method at present. 相似文献

Objective Postoperative pericardial effusion commonly occurs after open heart surgery. However, after general thoracotomy such as pulmonary
resection, there have been few reports of pericardial effusion. The purpose of this study is to investigate patients with
pericardial effusion following pulmonary resection.Methods: Among 2,385 patients with pulmonary resection for lung neoplasm in our institute, eight patients, whose pericardium had
never been opened during the operation, developed pericardial effusion. The clinical characteristics of the eight patients
were analyzed.Results: Pericardial effusion after pulmonary resection was divided into two subtypes: pericardial effusion in three patients with
left thoracotomy occurring within 30 days postoperatively, and pericardial effusion in the remaining five patients with right
thoracotomy occurring more than 30 days postoperatively. Pericardiotomy or pericardiocentesis was performed in three symptomatic
patients, and the remaining five asymptomatic patients were treated with diuretics. Pericardial effusion disappeared in three
of the five patients about 1–3 months after the conservative treatment, while, in the remaining patients, because pericardial
effusion had increased gradually, pericardiocentesis was performed.Conclusion: From our experience, the treatment strategy of drainage for early pericardial effusion and diuretics for late pericardial
effusion seems to be appropriate. (Jpn J Thorac Cardiovasc Surg 2006; 54:193-198) 相似文献

We have investigated the effects of short-contact topical application of tretinoin using 16 male db/db mice by creating two full-thickness wounds on the skin of the back. A 0.1% tretinoin aqueous gel was applied to one wound for five minutes daily for five successive days while only aqueous gel was applied to the other (control). The mean (SD) percentage surface area unhealed before and after treatment were 0.88 (0.3) and 0.64 (0.15). In tretinoin-treated mice and non-treated mice (controls), the mean (SD) thicknesses of granulation were 1.383 (697) micro m and 683 (413) micro m, the density of capillary vessels in granulation was 12.2 (5.5)% and 5.7 (3.9)%, respectively. Differences between the two groups were significant for each variable. Wound healing was accelerated with short-contact topical application of tretinoin in db/db mice. 相似文献

Combined measurement of serum prostate-specific antigen (PA) and prostatic acid phosphatase (PAP) was performed in 235 patients with various urologic diseases including 55 patients with prostatic cancer. A PA level of over 24.7 ng/ml and a PAP level of over 3.1 ng/ml were considered to be positive. The positive rate of PA was 57% in the patients with untreated prostatic cancer and 3% in the patients without prostatic cancer. The positive rate of PAP was 52% in the patients with untreated prostatic cancer and 1% in the patients without prostatic cancer. PA and PAP were considered to be equally sensitive and specific serum markers of prostatic cancer. However, the positive rate increased to 65% without increasing the false positive rate when the PA and PAP were both measured simultaneously. The combined assay of PA and PAP is recommended for screening prostatic cancer. The cross-over titer of PA and gamma-Sm using standard samples in each kit revealed linearity, which suggested that PA and gamma-Sm possess the same antigenicity. 相似文献

A total of 260 patients underwent treatment with extracorporeal shock wave lithotripsy (ESWL). Staghorn calculi were found
in 32 cases. In carrying out ESWL for staghorn calculi, double pigtail stent was previously retained in principle. When the
ureter was occluded by stone street in case a fever of more than 38° C lasted for 4–5 days after the first treatment with
ESWL, percutaneous nephrostomy (PNS) was performed. In ESWL treatment alone a large number of shock waves were required, but
double pigtail stent and PNS were used in combination individually, and larger stones were treated by the same waves. When
combination therapy was used, hospital stay was short and the rate of remaining stones was low. Our therapeutic conclusions
are discussed. 相似文献
