A 49-year-old man with an osteosclerotic lesion of a thoracic vertebra had peripheral neuropathy, lymphadenopathy, and elevated serum alkaline phosphatase and monoclonal immunoglobulin levels in the cerebrospinal fluid. These findings, not usually seen in ""classical'' myeloma, have been noted in different combinations in the osteosclerotic variety.

Institutionalized epileptic patients on long-term anticonvulsant diphenylhydantoin (DPH) therapy were examined clinically. DPH plasma levels were unexpectedly high in 54% despite rather poor seizure control. No patient was free from side effects, which included gingival hypertrophy (90% of patients), increased alkaline phosphatase activity (55%), suggestion of a sensory peripheral neuropathy (34%), central nervous system (CNS) intoxication (22%), coarsened facial features (19%), tendency to bleed excessively (15%), hirsutism (12%), and mild megalocytic anemia (5%). CNS intoxication correlated with high plasma DPH levels, reports of deteriorating behavioral and motor performance, and the findings of nystagmus on vertical gaze or truncal ataxia, though not all patients with high plasma levels were clinically intoxicated. Alarming were the often disfiguring changes of gums and facial structures and the tendency to develop signs of vitamin D deficiency secondary to therapy. Hirsutism was rare in black patients. Plasma DPH level determinations are recommended as part of the management of mentally retarded epileptic patients but do not replace clinical acumen and skill.

The observation of a non-metastatic reactive hepatopathy associated with a hypernephroma in a 39-year-old man who had had fever for 4 months led to a review of the literature and an analysis of basically three aspects of the disorder: a) The various manifestations of carcinoma of the kidney, which include a large number of paraneoplastic clinical symptoms (polycythemia, anemia, prolonged fever, hypercalcemia, hypertension, nefropathy, loss of salt, peripheral neuropathy, and amyloidosis); b) an alteracion of hepatic function known since 1961 which is characterized by an abnormal retention of sulfobromophthalein, increase of alkaline phosphatase, prothrombin decrease, dysproteinemia with hypoalbuminemia, and alpha2-globulin increase. It may or may not be accompanied by enlargement of the liver. c) Criteria of operability of the primary tumor.

Physicians and surgeons have long recognized that septic illness may be accompanied by abnormal brain functions; however, no systematic, comprehensive study has been done to define the clinical and laboratory features of the syndrome of sepsis-associated encephalopathy. We undertook such a prospective study in a tertiary care hospital and found that of 69 patients with fever and microbial cultures, 32 had marked brain dysfunction, 17 showed mild encephalopathy, and 20 were clinically nonencephalopathic. Severe cases showed obtundation and paratonic rigidity while milder cases showed confusion, inappropriate behavior, inattention, disorientation, and writing errors. There were no focal neurological deficits. The following factors correlated with the severity of brain dysfunction: adult respiratory distress syndrome; fatal outcome; certain types of EEG abnormality; axonal peripheral neuropathy; elevated peripheral white blood cell count; elevated serum levels of alkaline phosphatase, bilirubin, creatinine, phosphate, potassium, and urea; reduced blood pressure and reduced serum albumin level. Our data suggest that brain functions fail with dysfunction of other organs in septic illness. Pathogenetic mechanisms are discussed. The brain dysfunction should be regarded as potentially reversible, even in severely encephalopathic cases. Prompt control of the infection is the most important measure in controlling the encephalopathy and in preventing the increased mortality found with severely encephalopathic patients.

A drug schedule has been devised based on a strategy of G2 blockade followed by prolonged infusion of tubulin-binding agents. The regimen consists of doxorubicin 32 mg/m2 i.v. and cyclophosphamide 320 mg/m2 i.v. on day 1 followed by vinblastine (0.3 to 1.2 mg/m2/day), cisplatin (3 to 12 mg/m2/day), and vincristine (0.04 to 0.16 mg/m2/day) by continuous intravenous infusion on days 5 to 12. Courses are repeated every 28 days. Eighteen patients with advanced solid tumors received 37 courses of chemotherapy in a pilot study to determine safe drug concentrations for the three-drug infusion for 7 days. Dose limiting toxicity was myelosuppression. Patients who received prior mitomycin-C experienced more profound thrombocytopenia than those who did not. Nonhematologic toxicities included mild nausea, vomiting, and transient elevations of serum alkaline phosphatase and serum creatinine. One patient with squamous cell carcinoma of the esophagus who erroneously received vincristine 0.8 mg/m2 instead of 0.08 mg/m2 for 4 1/2 days developed transient myalgia, ileus, and a transient peripheral neuropathy; the patient achieved a sustained complete remission for 15 months and died of unrelated causes. Minor responses and stable disease were seen in two patients with renal cell carcinoma (1 and 2.5 months), three patients with colorectal carcinoma (1.5, 2, and 4 months), and one patient with squamous cell carcinoma of the tongue (2 months). The ViVACCy drug regimen can be given without undue toxicity and may be active in solid tumors.

An immunocytochemical study of alpha 1-antichymotrypsin (alpha 1ACT) was performed in order to demonstrate its localization and the relationship between alpha 1ACT and senescent cerebral amyloid. We examined 5 brains with dementia of the Alzheimer type (SDAT), a peripheral nerves of familial amyloidotic polyneuropathy (variant transthyretin type, FAP) and dorsal root ganglions of a primary amyloidosis with peripheral neuropathy (AL type, PA). Avidin-biotin-peroxidase complex method and double immunoenzymatic staining method (peroxidase-antiperoxidase method combined with avidin-biotin-alkaline phosphatase complex method) were used. Anti-beta protein serum was used as the marker of cerebral amyloid. About 98% of senile plaques had alpha 1ACT like-immunoreactivity (alpha 1ACTI). All types of plaques showed the immunoreactivity: Core and peripheral of typical plaques, primitive plaques, core plaques and amorphous cerebral amyloid deposits. Although, a part of a senile plaque showed beta protein like-immunoreactivity alone and the other part had alpha 1ACT, many remainder part of a senile plaque had both immunoreactivity. Of the other pathological changes of SDAT, eosinophilic tangles and cerebrovascular amyloid were positive, in contrast, intracellular tangles, granulovacuolar degeneration and Hirano body were negative. The amyloid from FAP had weak alpha 1ACTI and diffusely stained. alpha 1ACTI was seen in the peripheral margin of the amyloid from PA. These results indicate that alpha 1ACT is closely associated with senile plaques formation.

Primary biliary cirrhosis (PBC) is a chronic nonsuppurative, destructive cholangitis, whose etiology is unknown. Morbidity arises early from pruritus and later from hypercholesterolemia with xanthoma formation. Therapy is supportive and directed at the complications of cholestasis. Plasmapheresis has been reported to benefit patients with hyperlipidemia and PBC; thus a pilot study of plasmapheresis utilizing the Haemonetics Model 30 with replacement by albumin and saline was conducted. Five patients (four female and one male) with a mean age of 43 (range 29-58) and a mean duration of illness of 9.5 years (range 6-21) with marked jaundice, xanthomas, xanthelasma, hepatomegaly, fatigability, anorexia, and pruritus, as well as mild nausea were studied. Peripheral neuropathy was present in two patients. Two patients had splenomegaly. Two patients had an associated Sjogren syndrome. All patients had high serum bilirubin, alkaline phosphatase, and cholesterol levels and mild elevations in aspartate amino transferase and alanine amino transferase activities. Immune complexes measured in four patients were present. Antimitochondrial antibody titers were significant in all patients. Patients underwent a mean of 63 plasmapheresis procedures over a mean of 112 weeks removing a mean of 94.7 liters of plasma. No serious toxicity was seen. All patients showed a reduction in pruritus, xanthomas, xanthelasmas, and serum cholesterol values. The two patients who had evidence of Sjogren syndrome noted subjective improvement. All patients who had fatigue, anorexia and nausea also noted moderate improvement. There was no change in hepatomegaly or splenomegaly in patients demonstrating such organomegaly. Liver function did not change significantly. Overall, four patients had improvement in their condition and one patient achieved stability.(ABSTRACT TRUNCATED AT 250 WORDS)

Paclitaxel, a novel antimicrotubule agent that enhances tubulin polymerization and microtubule stability, was administered as a 24-hour infusion in a phase I study. Twelve patients received 32 courses at 50, 100, 150, and 200 mg/m2. A premedication regimen of dexamethasone, diphenhydramine, and ranitidine was used to prevent the acute hypersensitivity reactions (HSRs). The dose-limiting factor was leukopenia (granulocytopenia) associated with Grade 4 infection. The maximum tolerated dose was 200 mg/m2. Other non-hematological effects included peripheral neuropathy, myalgia, alopecia, and elevations of transaminase and alkaline phosphatase. Severe HSRs were not observed. The paclitaxel plasma concentration declined with a half-life of 10.0 to 24.9 hours. Excretion into urine within 72 hours was in the range of 7.28 to 11.34% of paclitaxel dosage. Two patients with breast cancer at the 200 mg/m2 dose level had partial responses. The recommended dose of paclitaxel for phase II study, when administered as a 24-hour infusion, is considered to be 150 mg/m2 every 3 weeks.

Significant osteoporosis determined by skeleton radiography and bone densitometry was found in 15 patients with cerebrotendinous xanthomatosis (CTX) whose mean age was 31 +/- 11 years. In three CTX patients, bone biopsies confirmed osteoporosis. Nine patients also sustained bone fractures following minimal trauma. Serum 25-hydroxyvitamin D ([25-OHD] 14.6 +/- 6.6 ng/mL v [normal] 30.4 +/- 8.0 ng/mL; P < .001) and 24,25-dihydroxyvitamin D ([24,25(OH)2D] 1.2 +/- 0.4 ng/mL v [normal] 2.7 +/- 0.8 ng/mL; P < .001) levels were low. Serum concentrations of 1,25(OH)2D, calcium, inorganic phosphorus, alkaline phosphatase, parathyroid hormone, and calcitonin were normal. Patients showed classic manifestations of CTX, including dementia, pyramidal and cerebellar insufficiency, peripheral neuropathy, cataracts, and tendon xanthomas associated with elevated serum cholestanol concentrations. These results demonstrate that extensive osteoporosis and increased risk of bone fractures are components of this inherited disease.

The tolerability and efficacy of four courses of paclitaxel and ifosfamide plus cisplatin every 3 weeks was evaluated in patients with residual or refractory ovarian cancer. Additionally, supportive haematological effects of recombinant human interleukin 3 (rhIL-3) and recombinant human granulocyte colony-stimulating factor (G-CSF) were studied. Paclitaxel starting dose was 135 mg m(-2) (day 1), with ifosfamide dose 1.2 g m(-2) day(-1) (days 2-4) and cisplatin dose 30 mg m(-2) day(-1) (days 2-4). All 16 patients received 5.0 microg kg(-1) day(-1) G-CSF (days 7-16) and, in addition, eight patients were randomized to receive 10 microg kg(-1) day(-1) rhIL-3 (days 5-9). Paclitaxel and ifosfamide doses were reduced when grade IV haematological toxicity occurred. In the absence of grade IV haematological toxicity and normal recovery of haematopoiesis, paclitaxel dose was escalated. Toxicity was evaluable in 56 courses, with haematological effects in 52. Despite antiemetic treatment, nausea and vomiting (> or = grade I) occurred in 50 courses. Five patients had persisting peripheral neuropathy. Renal and liver function were not affected. Grade IV neutropenia occurred in 12 out of 52 courses, with neutropenic fever in two patients, both of whom died from fatal septicaemia. Grade IV thrombocytopenia without bleeding was observed in 15 courses. Grade IV haematological toxicity was associated with hepatic metastases and concurrent increases in alkaline phosphatase (P <0.001) and gamma-glutamyltransferase (P=0.007). No relation was found between haematological toxicity and pharmacokinetic parameters of paclitaxel. Patients treated with rhIL-3 showed a tendency to a faster platelet recovery (not affecting platelet nadir), and the cisplatin dose intensity was higher (P=0.025). Six of the nine evaluable patients had a tumour response. The overall median progression-free survival was 7 months and the overall mean survival was 13 months. In conclusion, this potentially interesting combination as second-line treatment showed a low tolerability with unexpected mortality, while rhIL-3 administration tended to induce a more rapid platelet recovery.
