Renal involvement in 204 cases with multiple myeloma admitted over a 10-year period to this tertiary care center in north India was retrospectively examined. Renal involvement occurred in 55 cases (27%); the vast majority of whom (94.5%) had presented with renal failure and 7.3% had nephrotic syndrome. The diagnosis of multiple myeloma was made after admission in 51 of the 55 (92.7%) cases. Oliguria was seen in 23.6% and two-third patients required dialysis. Factors precipitating renal failure were identified in 53% and included dehydration (33%), hypercalcemia (24%), nephrotoxic drugs (16%), sepsis (9%), recent surgery (5%) and contrast media (2%), Severe anemia, hypercalcemia, Bence Jones proteinuria and skeletal abnormalities were more frequent in those with renal involvement. Patients with renal involvement were more likely to have a high tumor burden. The myeloma was of light chain type in 68% of those with renal involvement whereas IgG myeloma was commonest (57%) in those without evidence of renal disease. Renal histology was studied in 27 cases with myeloma cast nephropathy seen in over 60%. Tubulointerstitial nephritis was seen in 14% cases, 11% had amyloidosis, 7% had acute tubular necrosis and 3.6% each had nodular glomerulosclerosis and plasma cell infiltration. In 8 cases (14.6%), renal biopsy provided the first clue to the diagnosis of myeloma. Renal function improved in 33% cases. Only 22% of patients on dialysis survived over 6 months. Median survival in those with renal involvement was only 4 months. Development of unexplained renal failure in an elderly individual with normal sized kidneys, in association with disproportionate anemia even in the absence of skeletal lesions should alert the physician to the diagnosis of multiple myeloma.

We report a 67-year-old man with progressive disturbance of gait. He was well until the spring of 1993 (62 years of the age), when he noted an onset of unsteady gait. He also noted that he started to have a difficulty in playing tennis, in which he became unable to hit the ball with his racket. He also noted parkinsonian features such as bradykinesia and loss of hand dexterity. He was treated with levodopa, which did not improve his symptoms. His MRI revealed marked atrophy of the cerebellum and the pons. The criss-cross high signal lesion was seen in the center of the pons. The third ventricle was dilated. The putamen was unremarkable. His subsequent course was complicated by easy to fall, difficulty in swallowing with episodes of aspiration pneumonia. He also developed nocturnal apneustic episodes. He was admitted to our hospital on November 15, 1998, when he was 67 years of the age. He had low grade fever and low blood pressure (98/70). He was anemic but not icteric. Tumors were palpated in his jaw, anterior chest, and in the left arm. He was alert but unable to convey his desire because of dyspnea and tracheostomy. His gaze was slightly restricted in the horizontal direction and markedly so in the vertical direction. Motor functions were difficult to evaluate. His clinical course was complicated by atelectasis of the right lung and pleural effusion. He developed marked edema and oliguria. He developed sudden bradycardia and expired on December 26, 1998. He was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had multiple system atrophy. Majority of the audience agreed with this diagnosis. Post-mortem examination revealed a lung cancer in the right lung (undifferentiated adenocarcinoma) with metastases to the liver, kidneys, lymph nodes, pericardium, pleura, skin, bone marrow, and the brain. Neuropathologic examination revealed marked atrophy of the pons and the cerebellum. The putamen showed brownish discoloration and atrophic changes. The substantia nigra showed marked neuronal loss and gliosis. Oligodendrocytic inclusion bodies (alpha-synuclein positive) were seen in the putamen, globus pallidus, substantia nigra, pontine nucleus, cerebellar white matter, internal capsule, cerebral peduncle, and the spinal cord. These findings are consistent with the pathologic diagnosis of multiple system atrophy. What was interesting to us was the presence of neurofibrillary tangles in the substantia nigra, nucleus ruber, globus pallidus, and subthalamic nucleus. Tuft-shaped astrocytes were also seen. This patient appears to be a rare example of combination of MSA and PSP.

Tumor lysis syndrome, which develops after effective therapy of malignant conditions and leads to hyperuricemia, hyperkaliemia, hyperphosphatemia, hypocalcemia and elevated lactate dehydrogenase, is uncommon in solid tumors. In breast carcinoma it can be associated with tamoxifen flare, i.e. a transient increase in symptoms, mainly bone pain, observed shortly after the start of tamoxifen therapy. We report the case of a patient with advanced breast carcinoma involving the pleural space, unresponsive to combined chemotherapy, who experienced rapid worsening after the initiation of letrozole. Her symptoms included shock, bilateral pleural effusion, cardiac tamponade and oliguria. Laboratory parameters disclosed elevated transaminase, lactate dehydrogenase, uric acid and D-dimer blood levels. The patient was in critical condition for nearly 2 weeks. She improved progressively and has remained well and in complete remission for 20 months. This clinical picture suggests increased damage to the pleura (and probably the pericardium) and rapid leakage of tumor products, following the start of endocrine therapy. Letrozole is a non-steroidal aromatase inhibitor which is used in advanced breast cancer, resistant to first-line endocrine/chemotherapeutic treatment. Our review of the literature did not disclose any other descriptions of flare and tumor lysis syndrome after aromatase inhibitor therapy. Moreover, this case was characterized by atypical and complex clinical features. The aim of this presentation is to point out the practical significance, in neoplastic patients, of the differential diagnosis between symptoms due to tumor progression and those associated with anomalous reactions to therapy.

We report a case of clear cell adenocarcinoma of the urinary bladder. A 59-year-old male was referred to our hospital complaining of oliguria, left lower abdominal pain and loss of appetite. Ultrasonography revealed bilateral hydroureteronephrosis and obstructions at the ureterovesical junction. Magnetic resonance imaging demonstrated an invasive irregular tumor located in the posterior wall of the urinary bladder and urinary infiltration to the left retroperitoneal space. The clinical diagnosis was acute post renal failure due to bilateral ureteral obstructions from an invasive bladder tumor. After we performed bilateral percutaneous nephrostomy, the patient underwent trans urethral biopsy of the bladder tumor, which showed clear cell adenocarcinoma extending from the submucosa to the muscular layer, histopathologically. The patient died of metastatic disease 8 months after diagnosis. To our knowledge, the present case is the 23rd to be reported and demonstrates the shortest survival period in the related literature.

Compartment syndrome is classically considered a complication of a musculoskeletal injury. Recent research has confirmed the abdomen as a potential compartment with the capability to cause life-threatening local and systemic manifestations. Abdominal compartment syndrome (ACS) is precipitated by an acute increase in abdominal contents volume with resulting intraabdominal hypertension. Presenting signs of ACS include a firm tense abdomen, increased peak inspiratory pressures, and oliguria, all of which improve after abdominal decompression. Patients at risk for ACS include trauma (blunt or open), retroperitoneal hemorrhage, massive fluid resuscitation, pancreatitis, pneumoperitoneum, and neoplasm. Surgical decompression is the treatment of choice. The perianesthesia nurse plays a critical role in the team managing a patient at risk for abdominal compartment syndrome through intraabdominal pressure monitoring, wound care, and end organ perfusion support.

Veno-occlusive disease (VOD) is a rare complication of chemotherapy in children with cancer. In the literature successful treatment of severe VOD has not been well determined. The authors report a 5-year-old boy with Willms tumor whose condition was complicated with VOD while receiving chemotherapy. He was treated successfully with high-dose methylprednisolone. After therapy, the clinical signs of VOD, such as abdominal ascites, oliguria, and jaundice, disappeared without any adverse effects of therapy.

Acute spontaneous tumor lysis (ASTL) syndrome, an extremely rare disease, requires prompt recognition and aggressive management because it is fulminant at its outset, associated with severe metabolic derangement, and potentially reversible. We describe an unusual case in which spontaneous tumor lysis occurred in anaplastic large T-cell lymphoma associated with acute uric acid nephropathy, persistent oliguria, and shock. This case contrasts markedly with previously reported cases of ASTL syndrome, which developed mainly in the pathologic type of Burkitt lymphoma. To our knowledge, this is the first reported occurrence of ASTL syndrome associated with anaplastic large T-cell type lymphoma. This report also chronicles our successful experience with continuous renal replacement therapy in the presence of compromised hemodynamic status.

We report a case of squamous cell carcinoma of the ureter. A 62-year-old woman had undergone total cystectomy and ileal conduit because of squamous cell carcinoma of the bladder when she was 44 years old. Seventeen years later, she complained of edema and oliguria. Antegrade pyelography and loopography revealed a left ureteral tumor. She underwent left ureterectomy and extirpation of the conduit. Pathological diagnosis was moderately differentiated squamous cell carcinoma of the ureter, pT2. The patient is alive without recurrence or metastasis in the first year after surgery.

A 68-year-old woman was admitted to our hospital because of severe oliguria and macrohematuria. She was diagnosed as postrenal acute renal failure, because of bilateral dilatation of the renal pelvis on abdominal computed tomography (CT). Percutaneous nephrostomy was performed after hemodialysis was initiated. Next, urinary volume and serum creatinine level were normalized. Percutaneous biopsy towards the mass in the peritoneal cavity under abdominal CT revealed adenocarcinoma, although the primary site of the carcinoma could not be identified. Autopsy was permitted after her sudden death. It revealed that the primary carcinoma was a right pelvic and ureteral tumor. The right pelvic and ureteral tumor was composed of a mixture of transitional cell carcinoma and adenocarcinoma.

A 55 yr-old man presented with progressive muscle weakness and oliguria for 5 days. Laboratory findings suggested rhabdomyolysis complicated with acute renal failure. A diagnosis of polymyositis was based upon the proximal muscle weakness on both upper and lower limbs, elevated muscle enzyme levels, muscle biopsy findings and the needle electromyography findings. The muscle biopsy showed extensive muscle necrosis and calcification. Investigations for underlying malignancy demonstrated hepatocellular carcinoma. The patient was managed with hemodialysis and high dose prednisolone. His renal function was fully recovered and his muscle power did improve slightly, but he died of a rupture of the hepatic tumor. In our view, this is an interesting case in that the hepatocellular carcinoma was associated with polymyositis and fulminant rhabdomyolysis-induced acute renal failure requiring hemodialysis.
