    Notes: Abstract The standard surgical treatment of vasculogenic impotence or hip claudication involves repairing vascular lesions, especially in the internal iliac arteries. It is difficult, however, to make a definite diagnosis or an accurate judgement of the therapeutic effects of this treatment due to the trouble in ruling out any other disorders. During the last five years, 19 patients with impotence and associated apparent internal iliac artery stenosis or occlusion and 2 patients with hip claudication, underwent internal iliac arterial reconstruction. The patients’ ages ranged from 37 to 70 with a mean age of 63.7 and the main procedure performed in all patients was aorto-iliac to femoral bypass grafting, or abdominal aortic aneurysmectomy. A retrospective study revealed that 74 per cent of those treated regained penile erectile activity postoperatively, and that hip claudication disappeared completely in all cases. One of the patients received percutaneous transluminal angioplasty (PTA) for the treatment of vasculogenic impotence, after which his postoperative penile brachial pressure index (PBPI) improved, demonstrating a statistically significant difference compared to the preoperative value. Trans-anal Doppler measurement also proved useful in providing complication-free perioperative understanding of pelvic circulation.

    Notes: Abstract The intraoperative transcutaneous partial pressure of oxygen (PtcO2) was used to monitor 58 vascular reconstructive surgery procedures in 54 patients. The study comprised three groups: Group A (24 limbs without any ischemic symptoms or signs), Group B (45 limbs with intermittent claudication), and Group C (12 limbs with ischemic rest pain, ulceration, and gangrene). In addition in 31 patients the chest wall was monitored simultaneously as a control. The results showed that the PtcO2 values increased immediately and significantly to varying degrees and at varying speeds after unclamping. The controls had higher values than Group A (P〉0.05), Group B (P〈0.05), and Group C (P〈0.05) patients. Further study showed that there were no significant differences between the maximal values in the limbs with good distal vessel run-off in Groups A, B, and C, and in the controls (P〉0.05). It is thus concluded that effective vascular reconstruction in the limbs is indicated by a rapid and marked increase of both the PtcO2 value and the response value, while with a slow and low increase of the value, early graft failure and poor distal vessel run-off should be suspected. We believe that this monitoring method dynamically reflects the functional state during vascular reconstruction and is clinically valid.

    Cloacogenic anal carcinoma presenting with humoral hypercalcemia: Report of a case (1995)

    Notes: Abstract We present herein the case of a 60-year-old man found to have a rare type of cloacogenic anal carcinoma. The disease was advanced and aggressive with local invasion to the prostate as well as distant lymph node metastases to the neck and paraaortic region on presentation. Therefore, a palliative abdominoperineal resection was performed, 10 weeks following which the patient developed humoral hypercalcemia. Despite treatment with hydration, furosemide, steroids, and calcitonin, serum calcium continued to rise and the patient died on the 95th postoperative day. Laboratory findings revealed a decreased parathyroid hormone (PTH) level and marked elevation of parathyroid hormone-related protein (PTHRP). The detection of the PTHRP in the tumor extract and the positive immunohistochemical staining for this in the tumor cells suggested that the humoral hypercalcemia was definitely caused by its associated tumor production. Although hypercalcemia is not an uncommon complication of solid cancers in their late stage, only three other cases of rectal cancer with hypercalcemia have ever been reported. To our knowledge, this is the first documentation of cloacogenic anal carcinoma accompanied by PTHRP-induced severe humoral hypercalcemia.

    The synthesis and thermal behaviour of magnesium bis(phosphorodiamidate) (1989)

    Notes: Abstract Magnesium bis(phosphorodiamidate) hexahydrate, Mg[PO2(NH2)2]2 · 6H2O, was made by the wet process. The phosphorodiamidate was stable below 5° C, but it was converted to phosphoramidate, orthophosphate, and polyphosphates above 30° C in air. When the phosphorodiamidate was heated in air or in dry nitrogen at a higher temperature, it produced phosphoramidate, ortho- and polyphosphates, and polyphosphates with imino groups. The thermal products in air and in dry nitrogen finally gave Mg(PO3)2 associated with the following reaction at a higher temperature than about 700° C Mg[PO2(NH2)2]2·6H2O→Mg(PO3)+4NH3+4H2O and the product in dry nitrogen still contained 3 to 4% nitrogen.

    Notes: Abstract Sodium phosphorodiamidate pentahydrate, NaPO2(NH2)2·5H2O, was made by saponifying phenyl phosphorodiamidate with a 4 mol dm−3 aqueous sodium hydroxide solution. The product was stable below 5° C, but it decomposed gradually to phosphoramidate and orthophosphate at 30° C. The phosphorodiamidate produced imidopolyphosphates and polyphosphates other than phosphoramidate and orthophosphate when it was heated above 30° C, and was finally converted to sodium metaphosphate above 300° C in air.
