Signet ring cell adenocarcinoma of the bladder: linitis plastica variant.

An unusual case of the signet ring cell variant of adenocarcinoma of the bladder occurred in which the tumor extensively infiltrated the bladder wall and perivesical fascia. The pattern of infiltration was analogous to that seen in the linitis plastica variant of gastric carcinoma. Cystoscopic and roentgenographic studies failed to reveal a grossly evident lesion.

Benign chondrolipomatous tumour of the breast.

Cartilage associated with malignant neoplasms of breast has been known and documented for over 200 years. Benign breast tumours containing cartilage are rare. A case of such a tumour was encountered.

Uterine lipomas.

Pure lipoma of the uterus is a rare entity and few authenticated cases have been recorded. We studied three cases of uterine lipomas. These are typical in their clinical, gross, and microscopic findings, appearing clinically as leiomyomas of the uterus.

Lipid cell tumor of the ovary.

A 32-year-old nulligravida, with a history of abdominal hysterectomy for multiple leiomyomas of the uterus, was seen initially with signs of masculinization. Normal values for 17-ketosteroids, 17-hydroxycorticosteroids, and plasma cortisol eliminated the adrenal as the source of the excess androgen as well as Cushing syndrome. Increased plasma testosterone and androstenedione levels in the peripheral blood as well as in the right ovarian vein sampling implicated the right ovary, which revealed a lipid cell tumor (0.

Geomorphic reconstructions in the environs of ancient troy.

Sea level rise, deltaic progradation, and floodplain aggradation have changed the landscape in the vicinity of ancient Troy during the past 10,000 years. With the waning of the last major world glaciation and resultant sea level rise and fluctuation, a marine embayment protruded nearly 10 kilometers south of the site of Troy at Hisarlik in the Troad of northwest Turkey. As the sea approached its present level approximately 6000 years ago, fluvial and marine deposition caused a northerly migration of the delta and floodplain of the Scamander and Simois Rivers past the site of Troy toward the present-day coast about 6 kilometers north of the site.

Undifferentiated sarcoma arising in an augmented ileocystoplasty patch.

We report an unusual case of a sarcoma at the patch site of an ileocystoplasty. The tumor proved to be an aggressive neoplasm that metastasized widely. The literature is reviewed concerning neoplasms occurring in urinary diversion procedures.

Crescentic osteotomy for fifth metatarsal head lesions.

The use of orthotics may make surgery for fifth metatarsal lesions unnecessary. If surgery is required, several procedures currently used are effective; however, the authors believe crescentic osteotomy to be the procedure of choice for several reasons--it is less traumatic, less destructive to the joint, does not require internal fixation, is less demanding technically, and requires a shorter postoperative period of convalescence. Although the most common deformity of the fifth ray is in the sagittal plane, it is possible to correct various positional deformities by altering the plane of osteotomy.

Use of an autogenous hypogastric artery patch graft for living related donor kidneys with multiple renal arteries.

A kidney with triple renal arteries was removed from an HLA identical donor and transplanted to her brother using the donor hypogastric artery as an autogenous graft. The kidney was preserved by hypothermic, hyperkalemic, hyperosmolar washout solution while the three separate renal artery-hypogastric artery autograft anastomoses were being performed in an ex vivo position. Subsequently, the end to side autogenous hypogastric artery patch graft to external iliac artery anastomosis was completed.

Diagnostic value for acute myocardial infarction of creatine kinase and lactate dehydrogenase isoenzymes compared with total enzymes. Creatine kinase isoenzyme specificity for myocardial damage.

The diagnostic value of creatine kinase (CK) and lactate dehydrogenase isoenzymes was investigated in a prospective study of 201 patients with suspected acute myocardial infarction (AMI). The isoenzymes were analyzed with a column chromatographic method. The patients' final diagnoses were made according to the WHO criteria without knowledge of the isoenzyme results.

Paleogeographic reconstructions of coastal aegean archaeological sites.

Many studies have been made of ancient Greek topography, some of the more recent ones based on modern techniques. However, most still ignore the subsurface dimension of coastal and other environments and hence fail to fully explain coastal and alluvial-colluvial processes, rates of change of geomorphology, and the effects of coastal change on humans. In this article subsurface geological analyses have been used to elucidate paleogeographic coastal settings of major archaeological sites around the Aegean Sea.

Polymethylmethacrylate--a review.

Methylmethacrylate, an acrylic plastic used in dentistry, has recently been adapted as a cement in bone surgery. It has proved to be useful in implant surgery and total joint replacement, in malignant neoplastic fractures, and in the fixation of pins and screws in bone. However, problems such as recurring infections, thermal necrosis of tissue, depression of myocardial and hepatic function, and leakage of monomer may occur with the use of methylmethacrylate.

The natural history of symptomatic recurrent bacteriuria in women.

In 23 adult women having uncomplicated recurrent urinary tract infections treated with 10 days of appropriate antibiotic for each infection, the following findings were noted. 1. The attack rate was 0.
