This study explored medical conditions associated with mortality among veterans following transfemoral amputation, transtibial amputation, or hip disarticulation. We applied logistic regression models to identify clinical factors associated with mortality postoperatively. The participants included patients with lower-limb amputations (n = 2,375) who were discharged from Veterans Health Administration hospitals between October 1, 2002, and September 30, 2003. Most (98.9%) were male. We measured cumulative in-hospital, 3-month, and 1-year mortality. The results were 180 in-hospital deaths, 368 by 3 months, and 634 by the 1-year postsurgical amputation date. Those who had perioperative systemic sepsis (odds ratio = 4.28, 95% confidence interval = 2.87-6.39) had more than a fourfold increased likelihood of in-hospital mortality. Congestive heart failure, renal failure, and liver disease were significantly associated with mortality at all time periods. Metastatic cancer was associated only at 3 months and 1 year. We concluded that high medical complexity and mortality rates attest to the need for careful medical oversight during the postacute rehabilitation period.

Neuroblastoma is a tumor of the sympathetic ganglia and adrenal medulla that rarely metastasizes to the placenta. A 21-year-old gravida 3, para 1 at 28 weeks' gestation had an incidental finding of a 3.8-cm fetal renal mass on prenatal ultrasound. Within 1 week, the fetus developed hydrops and was delivered for nonreassuring fetal assessment. The mother developed mirror syndrome as manifested by hypertension, oliguria, and edema. The hydropic infant developed pulmonary hypertension, sepsis, and renal failure. On day of life 4, life support was discontinued. Pathological examination of the placenta revealed disseminated small round blue cells consistent with neuroblastoma. Metastasis of congenital neuroblastoma to the placenta is exceedingly rare, and cases discovered prenatally have resulted in significant maternal morbidity and 100% neonatal mortality.

Nephrotic syndrome due to membranous glomerulonephritis is observed in 1 to 3% of patients with lung cancer. The nephrotic syndrome usually precedes the discovery of the causal tumor, but diagnosis can be concomitant or during the disease course. We describe a case of small-cell carcinoma of the lung without metastases revealed by a paraneoplastic nephrotic syndrome. Complete remission of the tumor was achieved with chemotherapy and radiotherapy with resolution of the nephrotic syndrome, but tumor progression occurred together with rapidly fatal renal failure. In this case, and the review of the literature, illustrate the association between paraneoplastic nephrotic syndrome and lung cancer, as well as the disease course and prognosis of the lung cancer and the accompanying glomerulopathy.

We report clinicopathologic features of a large series of renal translocation carcinomas from a multicentric study. Diagnosis was performed by cytogenetic examination of fresh material and/or by immunochemistry with antibodies directed against the C-terminal part of transcription factor E3 (TFE3) and native transcription factor EB (TFEB) proteins. Clinical data, follow-up, and histologic features were assessed. Antibodies against CK7, CD10, vimentin, epithelial membrane antigen, AE1-AE3, E-cadherin, alpha-methylacyl-coenzyme A racemase, melan A, and HMB45 were tested on tissue microarrays. Whole-genome microarray expression profiling was performed on 4 tumors. Twenty-nine cases were diagnosed as TFE3 and 2 as TFEB renal translocation carcinomas, including 13 males and 18 females, mean age 24.6 years. Two patients had a previous history of chemotherapy and 1 had a history of renal failure. Mean size of the tumor was 6.9 cm. Thirteen cases were > or = pT3 stage. Twelve cases were N+ or M+. Mean follow-up was 29.5 months. Three patients presented metastases and 5 have died. Mixed papillary and nested patterns with clear and/or eosinophilic cells represented the most consistent histologic appearance, with common foci of calcifications regardless of the type of translocation. Using a 30 mn incubation at room temperature, TFE3 immunostainings were positive in only 82% of our TFE3 translocation carcinomas. Both TFE3 and TFEB renal translocation carcinomas expressed CD10 and alpha-methylacyl-coenzyme A racemase in all cases. An expression of E-cadherin was observed in two-third of cases. Cytokeratins were expressed in less than one-third of cases. Melanocytic markers were expressed at least weakly in all cases except two. Unsupervised clustering on the basis of the gene expression profiling indicated a distinct subgroup of tumors. TRIM 63 glutathione S-transferase A1 and alanyl aminopeptidase are the main differentially expressed genes for this group of tumors. Our results suggest that these differentially expressed genes may serve as novel diagnostic or prognostic markers.

We report 2 cases of renal cell carcinoma (RCC) in which the tumor arose from a transplanted allograft. The first case is a 52-year-old man with a failed cadaveric renal transplantation found to have metastatic RCC. The tumor was proven to be from the allograft, as fluorescence in situ hybridization analysis of biopsy material showed a female karyotype, consistent with his female donor. The second patient is a 45-year-old man who had undergone cadaveric renal transplantation in 1985 for chronic glomerulonephritis and, after 22 years, presented with renal failure. Biopsy and subsequent allograft nephrectomy revealed innumerable microscopic foci of RCC. There are only a few reported cases of RCC arising in kidney allografts and even fewer with reports of metastatic disease from the allograft. Treatments in patients with disease confined to the kidney have included partial nephrectomy and total nephrectomy. A literature search did not find any reports of treatment of metastatic RCC that arose from a renal allograft.

Spinal fusion surgery has increased dramatically and patients presenting for surgery are often more medically challenging. We hypothesized that advanced age and coexisting morbidities have increased in the population undergoing spinal fusion and are associated with greater risks for immediate complications and mortality. The Nationwide Inpatient Sample was retrospectively reviewed for discharges after a principal procedure code for elective spinal fusion. Total records meeting study inclusion criteria were 254,640. Coexisting morbidities were tabulated using Elixhauser comorbidities and the Charlson comorbidity index. Logistic regression identified risk factors associated with in-hospital mortality and early complications. The largest increase in spinal fusion surgery was in patients >65 years. Overall, those with at least 1 comorbidity increased (49% to 62%; P=0.002), as did mean Charlson index (0.146 to 0.202; P<0.001). In-hospital mortality was 0.13%, but 0.29%, and 0.64% for patients of 65 to 74, and those >or=75 years, respectively. Adjusted odds ratios for complications in 65-year to 74-year olds versus <65 years was 1.78 (95% confidence interval, 1.71-1.84; P<0.001), and for mortality 3.81 (95% confidence interval, 2.62-5.55; P<0.001); risks increased with the number of coexisting morbidities. Congestive heart failure, chronic pulmonary disease, coagulopathy, metastatic cancer, renal failure, and weight loss significantly correlated with in-hospital mortality, whereas hypertension or hypothyroidism had, unexpectedly, the opposite effect. Although it is known for some other forms of complex surgery, we showed that elderly and medically complex spinal fusion patients were at increased risk for in-hospital mortality and early complications. The majority of complications were operative, pulmonary, cardiovascular, or genito-urinary. Patient risk correlated with the number and nature of coexisting morbidities.

The treacherous and deceptive nature of pheochromocytoma makes it crucial to detect and treat it promptly; otherwise it will almost certainly be fatal from cardiovascular complications or metastases. Hypertension occurring in patients with pheochromocytomas is sustained in about 50% and paroxysmal in the remainder; however, many patients remain normotensive. Hypertension attacks may be precipitated by physical activity, postural changes, anxiety, certain foods or wine, some drugs, operative procedures, etc. Cardinal manifestations are paroxysmal hypertension, headache, palpitations +/- tachycardia, inappropriate sweating; anxiety, tremulousness, pallor (rarely flushing), chest and abdominal pains; nausea and vomiting often occur. Hypercatecholaminemia manifestations are more common and pronounced when paroxysmal hypertension occurs, but persons with familial pheochromocytoma may be asymptomatic. Protean manifestations of pheochromocytoma may simulate many conditions, some of which may have elevated plasma and urine catecholamines and their metabolites. Baro-reflex failure, postural tachycardia syndrome, sleep apnea, carcinoid, renal failure, and pseudopheochromocytoma may be diagnostic challenges. The history, physical examination, biochemical testing (after eliminating interfering drugs, when possible) for plasma and urinary metanephrines can usually establish or exclude presence of pheochromocytomas. Occasionally a clonidine suppression test is needed to differentiate neurogenic from pheochromocytic hypertension. Manifestations suggesting hypercatecholaminemia without hypertension are highly atypical of pheochromocytoma. Pheochromocytoma may present as panic attacks, pre-eclampsia, cardiomyopathy, infection with fever and leucocytosis, diabetes, migraine, shock, Cushing's syndrome, multiple organ failure with lactic acidosis, neurological manifestations, transitory electrocardiogram abnormalities, constipation, intestinal obstruction, visual impairment, convulsions, etc. The key to diagnosis is always to think of pheochromocytoma in the differential diagnosis of hypertension.

Although prostate cancer is among the most frequent malignancies in the elderly, this tumor may be under-reported, and it seems that its socioeconomic burden is not well-estimated. Chronic urinary obstruction caused by the cancer may cause renal failure, with hemorrhagic tendency, neurologic disturbances, cutaneous disorders, and diverse fingernail changes. Black or brown nail pigmentation has been associated with benign and malignant conditions, including antineoplastic drugs' side effects, subungual metastases, and melanoma. Metastasis of fingernail melanoma can affect lymph nodes from the wrist to elbow and axillary regions. Coexistent melanonychia and wrist lump, mimicking melanoma with sentinel lymph node is reported. It is recommended to consider the differential diagnosis of nail changes due to chronic renal failure.

A 53-year-old woman suffering from nausea and vomiting was admitted to our hospital. There was a large ulcer from her left anterior chest to her right side chest. After pathological examination from the ulcer, she was diagnosed as breast cancer, scirrhous carcinoma. The estrogen and progesterone receptors were positive in the tumor. HER2 score was 1+ in the tumor. The stage was T4bNxM1(OTH). Uterine metastases of the breast cancer caused obstructive nephropathy. Ureteral obstruction was treated by urinary tract catheter. After improvement of renal failure, chemotherapy with 5-FU+epirubicin+cyclophosphamide (FEC) and docetaxel was performed. The efficacy was judged as stable disease (SD). For third-line chemotherapy, she was then treated with oral combination chemoendocrine therapy with capecitabine and medroxyprogesterone acetate. After the combination chemoendocrine therapy, the local tumor was remarkably reduced. With added cyclophosphamide, the partial response (PR) continued for 19 months. She died of peritonitis carcinomatosa and pleuritis carcinomatosa. No adverse reactions occurred with the combination chemoendocrine therapy. It is suggested that this oral combination chemoendocrine therapy may be useful with consideration for treatment effectiveness and the quality of life of the patient.

Hypercalcemic crisis, a life-threatening emergency, is defined as decompensated hypercalcemia presented with characteristic symptoms such as oliguria, cardiac arrhythmia, or coma. We report the case of a 63-year-old man diagnosed with mucosa-associated lymphoid tissue lymphoma and multiple bony metastases, who presented to the emergency department (ED) with coma and severe hypercalcemia (4.15 mmol/L). Prompt hydration with normal saline and intravenous pamidronate failed to correct his hypercalcemic coma. Calcium-free hemodialysis rapidly decreased the level of serum total calcium to 2.15 mmol/L after a 2-hour session, and the patient dramatically regained consciousness shortly after hemodialysis. Calcium- free hemodialysis has proved favorable for rapidly correcting hypercalcemia in the presence of severe hypercalcemic symptoms, congestive heart failure, renal failure, or other conditions that contraindicate adequate hydration. This case highlights the fact that for all patients with comas of questionable cause in the ED, hypercalcemia- induced coma must be considered, especially in patients with malignancies. Early diagnosis and prompt treatment with calcium-free hemodialysis not only rapidly improve patient consciousness but also prevent the fatal complication of hypercalcemia.
