Effects of the synthetic proteinase inhibitor, FOY, on hypercoagulability after surgery for esophageal carcinoma

Hypercoagulability develops after surgery for esophageal carcinoma, and it related closely to postoperative complications. This study evaluated the effects of the synthetic proteinase inhibitor, Cabexate Mesilate (FOY), on this hypercoagulability. The subjects used were 25 patients with a mean age of 63 who had undergone surgery for esophageal carcinoma. Of these, eight patients (test group) received FOY (2,000 mg/day) for three to 23 days after surgery, but 17 (control group) did not. In the test group, FOY controlled aggregation and release of the platelets and minimized their exhaustion. FOY almost completely checked the abnormal increase in thrombin activity which might trigger the hypercoagulability. Also, FOY suppressed the fibrinolytic activity slightly. These results indicate that FOY is effective in controlling hypercoagulability after surgery for esophageal carcinoma and in suppressing activity of the proteinases that cause both blood coagulation and fibrinolysis.     

A case of polycythemia vera complicated by chronic renal failure under hemodialysis requiring parathyroidectomy for secondary hyperparathyroidisim

A case of polycythemia vera complicated by chronic renal failure under maintenance hemodialysis requiring parathyroidectory (PTH) for secondary hyperparathyroidism (2° HPT) is reported. A 62 year old female presented with 75000 white blood cells (WBC)/μl, 703×10⁴ red blood cells (RBC)/μl, 23×10⁴ platelets (PLT)/μl, hyperuricemia and hypertension in 1970 and the diagnosis of polycythemia vera was made. Hemodialysis was started in October 1974 for chronic renal failure. Blood cells in peripheral blood rapidly decreased in number after the beginning of dialysis, reaching the level of 10000∼20000 WBC/μl, and 150∼250×10⁴RBC/μl. In August 1988, marked bone resorption in X-ray picture and high serum alkaline phosphatase and parathyroid hormone (PTH) noted along with 17400 WBC/μl, 370×10⁴RBC/μl and 35.9×10⁴PLT/μl. After subtotal PTX removing 3.21g parathyroid gland, serum PTH rapidly fell. At 3 months after PTX, WBC rose to 23600/μl, RBC 372×10⁴/μl and PLT 94.0×10⁴/μl. At 6 months, WBC was to 31000/μl, RBC 429×10⁴/μl and PLT 78.0×10⁴/μl, suggesting an inhibitory action of PTH on not only RBC, but also WBC and PLT.     

Nephron Sparing Surgery for De Novo Renal Cell Carcinoma in an Allograft Kidney: A Case Report

De novo renal cell carcinoma in a renal allograft is rare and has special implications in renal transplant recipients. We describe a patient with a renal allograft who developed a de novo renal cell carcinoma in the functioning renal allograft 258 months after transplantation. The patient underwent enucleation of the tumor because preoperative MRI showed it was well-encapsulated. A DNA banding study showed that the tumor originated from the donor. Indications for conservative renal surgery in renal cell carcinoma have been increasing. Accordingly, 1 option in the treatment of de novo renal cell carcinoma in a functioning renal allograft is enucleation as a method of nephron sparing surgery.     

Visualization of left bronchial-to-coronary artery communication after distal bronchial artery embolization for bronchiectasis

We present a 44-year-old woman in whom a bronchialto-coronary artery communication via the conus branch was discovered after distal bronchial artery embolization with gelatin sponge for hemoptysis. If this bronchial-to-coronary artery anastomosis, not visible prior to embolization, had been inadvertently embolized, the patient could have developed a myocardial infarction. To reduce the likelihood of a serious complication, the possibility of this anastomosis should be kept in mind and angiography should be repeated before attempting proximal bronchial artery embolization.     

Cytokines as an adjuvant to tumor vaccines: Efficacy of local methods of delivery

Background: We examined alternative methods of delivering cytokines as an adjunct for priming lymph node (LN) cells draining sites of vaccine inoculation for the purpose of generating immune cells for adoptive immunotherapy. Methods: Using syngeneic murine tumors we examined the ability of IL-2, IL-4, or GM-CSF delivered locally to a site of tumor inoculum to induce antitumor reactive draining LN cells. Mice were inoculated subcutaneously with tumor cells transduced to secrete cytokine; tumor cells admixed with fibroblasts transduced to secrete cytokine; or intralesional inoculation of cytokine in established tumor to induce sensitized LN cells capable of mediating tumor regression in adoptive transfer. Results: Both IL-4 and GM-CSF cytokines were effective in enhancing the antitumor reactivity of vaccine-primed LN cells compared to IL-2, which was ineffective. The local delivery of GM-CSF by autocrine or paracrine secretion of genetically engineered cells, as well as direct intratumoral delivery was capable of upregulating LN sensitization compared to systemic administration, which did not. Conclusions: The local delivery of GM-CSF as an adjuvant for tumor vaccination can be accomplished by various methods, including direct injection, which avoids the need for gene transfer.     

Quality of the life in hypertensive outpatients]

In order to evaluate the quality of life (QOL) in hypertensive outpatients, we selected 78 patients with hypertension of various degrees of severity (WHO Classification I: 29 cases, II: 15, III: 34), 59 not ill healthy persons (N1) and 22 normotensive outpatients (N2) aged at 50 years and over, using the self-completed questionnaire (QUIK) which we developed. QUIK covers four domains including physical functioning (20 questions), emotional adjustment (10), interpersonal relationships (10) and attitudes toward life (10) totaling 50 questions. In this study the internal consistency of QUIK was alpha = 0.95 by the Kuder-Richardson formula 20 and it's repeatability was r = 0.89 by the Spearman-Brown formula. The QOL in hypertensive outpatients was definitely worse in terms of total score (N1 5.1 +/- 4.4 vs WHO II 9.3 +/- 7.2 and III 12.1 +/- 5.6, p < 0.05), for physical functioning (N1 2.5 +/- 2.1 vs WHO I 3.7 +/- 2.8, II 4.7 +/- 3.8, III 5.4 +/- 2.8 p < 0.05), for emotional adjustment (N1 1.2 +/- 1.4 vs WHO III 2.3 +/- 1.7, p < 0.01), for interpersonal relationships (N1 0.8 +/- 1.3 vs WHO III 1.6 +/- 1.5, p < 0.01) and for attitudes toward life (N1 0.7 +/- 1.2 vs WHO III 2.7 +/- 2.0 p < 0.01). The total QUIK score increased according to the severity of symptoms (WHO I 5.8 +/- 4.4, WHO II 9.3 +/- 7.2 and WHO III 12.1 +/- 5.6), respectively. The total score of WHO I was significantly lower compared with that of WHO III (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

A case of orbital apex syndrome caused by localized invasive aspergillosis successfully treated with voriconazole]

A 71-year-old man with left periorbital pain and diplopia was hospitalized for evaluation and treatment. He had a past history of untreated diabetes mellitus. Shortly after admission, the patient experienced rapid onset of visual loss in the left eye. MRI and CT showed a lesion expanding from the left orbital apex to the left pterygopalatine fossa. Invasive aspergillosis was diagnosed by open biopsy of intrasinus mucosa via the left maxillary sinus. The patient was treated with voriconazole, an antifungal agent, and marked improvements in left periorbital pain and eye movement were subsequently obtained, although visual acuity was not recovered. This is the first report documenting the clinical utility of voriconazole for sino-orbital invasive aspergillosis.     

A review of Disrupted-In-Schizophrenia-1 (DISC1): neurodevelopment, cognition, and mental conditions.

Disrupted-In-Schizophrenia-1 (DISC1) is a promising candidate gene for schizophrenia (SZ) and bipolar disorder (BP), but its basic biology remains to be elucidated. Accumulating genetic evidence supports that DISC1 is associated with some aspects of cognitive functions relevant to SZ and BP. Here, we provide a summary of the current updates in biological studies of DISC1. Disrupted-In-Schizophrenia-1, preferentially expressed in the forebrain, has multiple isoforms with potential posttranslational modifications. Disrupted-In-Schizophrenia-1 protein occurs in multiple subcellular compartments, which include the centrosome, microtubule fractions, postsynaptic densities, actin cytoskeletal fractions, the mitochondria, and the nucleus. Recent studies have clarified that DISC1 mediates at least centrosome-dynein cascade and cyclic adenosine monophosphate (cAMP) signaling. Furthermore, both cytogenetic and cell biological studies consistently suggest that an overall loss of DISC1 function (either haploinsufficiency or dominant-negative, or both) may be associated with SZ and BP. On the basis of these findings, production of DISC1 genetically engineered mice is proposed as a promising animal model for SZ and BP. Several groups are currently generating DISC1 mice and starting to characterize them. In this review, the advantages and disadvantages of each animal model are discussed.
