    Notes: Abstract Among 230 patients undergoing ultrasound (US) guided renal biopsy, 218 had postbiopsy sonography. Clinical records were reviewed to correlate symptoms to US findings. In each case of large hematoma (thickness above 1 cm), all postbiopsy sonographic studies were analyzed to look for findings indicative of unfavorable outcome. A total of 96 subcapsular/perirenal hematomas were found. Large hematomas were observed in 20 patients (20/230=8.7%), seven of these (3%) were severely symptomatic. In the absence of clinical signs of bleeding, no patient had clinical consequences. In the presence of clinical signs of bleeding, serious complications occurred only in patients with large hematomas. US thickness of retroperitoneal hematoma correlated to clinical outcome: whenever measured thickness was less than 2 cm, clinical evolution was very favorable, whereas a thickness above 2 cm was invariably associated to clinical signs of bleeding. In six of seven cases of thickness exceeding 3 cm, severe complications developed. An unfavorable evolution was associated with increasing thickness and an echogenicity inappropriate with respect to the time elapsed since biopsy. Hydroureteronephrosis, peritoneal effusion, and anomalous vascular images were indicators of deterioration. We conclude that sonography is indicated only for symptomatic patients and that the monitoring of both thickness and changing echogenicity of retroperitoneal blood collections supplements clinical follow-up.

    Notes: Summary A new microorganism, isolated in our laboratories and identified as Streptomyces michiganensis var. amylolyticus var. nova is described. Thaimycins can be obtained by submerged fermentation of this microorganism on a suitable culture medium. Three new related compounds, thaimycins A, B and C have been obtained and characterized by their physical and chemical properties. Data on the antiprotozoal and anthelmintic activities in vitro as well as in vivo are reported.

    Notes: Background:  The aim of the present pilot study was to compare the analgesic efficacy of S(+)-ketamine either alone or in combination with neostigmine for caudal blockade in pediatric surgery.Methods:  A total of 40 children were randomly assigned to receive after induction of general anesthesia either caudal S(+)-ketamine 1 mg·kg−1 (group K, n = 20) or caudal S (+)-ketamine 0.5 mg·kg−1 plus neostigmine 10 μg·kg−1 (group KN, n = 20). Anesthesia was maintained with sevoflurane and a laryngeal mask airway (LMATM), no additional analgesics were administered. Postoperative pain and sedation were assessed by the Children's Hospital of Eastern Ontario Pain Score and Ramsay scale for 24 h.Results:  No statistical difference in duration of analgesia and sedation was found. Mean duration of postoperative analgesia was 18 ± 9.4 h in group K and 21.8 ± 6.7 h in group KN. There was a significantly higher incidence of postoperative vomiting after administration of caudal ketamine with neostigmine (30% group KN Vs 0% group K; P 〈 0.05).Conclusions:  This pilot study demonstrates equianalgesic effects on postoperative pain relief in children with both caudal S(+)-ketamine 1 mg·kg−1 and caudal S(+)-ketamine 0.5 mg·kg−1 plus neostigmine 10 μg·kg−1. Further studies are required to confirm adoption of caudal neostigmine into routine clinical practice.

    Notes: Riassunto Nonostante l'affinità strutturale con l'uabaina, lo spirolattone antialdosteronico SC 9420 non esercita la stessa azione del glicoside cardiocinetico sugli scambi attivi che si manifestanoin vitro attraverso la membrana di eritrociti umani incubati a 37°C dopo 6 giorni di conservazione a 4°C. Non trova quindi conferma sperimentale l'ipotesi che entrambe queste sostanze competano con l'aldosterone in qualche fase del processo enzimatico di trasporto degli elettroliti a livello di tutte le membrane cellulari dell'organismo.

    Notes: Riassunto È stato studiato il meccanismo di scambio cationico di membrana di emazie umane normali trattate con composti sulfidrilici (AET e cisteina). Si è osservato che, durante l'incubazione di 3 h a 37°C, effettuata dopo 5 giorni di soggiorno a 4°C, le emazie normali trattate con i suddetti composti rimuovono attivamente dal plasma normali quantitativi di K+. I risultati vengono brevemente discussi.

    Notes: Riassunto Viene descritto l'isolamento e lo studio chimico della mannosidoossistreptomicina, presente, insieme con ossistreptomicina, streptidina e toiocamicina, nelle colture delloStreptomyces 86. Il nuovo antibiotico ed il suo diidroderivato presentano una attività antibatterica paragonabile a quella di streptomicina e di ossistreptomicina.

    Notes: Summary The abnormalities of lipid metabolism in nephrotic syndrome consist in an increase in total and low-density lipoprotein (LDL) cholesterol, apoliproteins B (ApoB), C-II and C-III, associated in patients with heavier or marked hypoalbuminemia with an increase in triglycerides and very low-density lipoprotein (VLDL) cholesterol, while the high-density lipoproteins (HDL) are distributed abnormally (increased HDL3 fraction and decreased HDL2 fraction) and the Apo A-I to Apo B ratio is reduced. Both increased hepatic lipoprotein synthesis and reduced removal capacity contribute to this hyperlipidemia. Proteinuria may lead to the lipoprotein abnormalities through stimulation of VLDL synthesis by the liver induced by hypoalbuminemia, although it has been more recently suggested that urinary protein loss is associated with the urinary loss of some important cofactor for the regulation of lipid synthesis or catabolism. Treatment of lipid abnormalities in patients with long-lasting heavy proteinuria is mandatory, because they may cause or contribute to accelerated atherosclerosis, but also because they appear to accelerate progression of renal disease by favouring mesangial sclerosis. Four groups of lipidlowering drugs have been tested: 1) bile acid-binding resins; 2) fibric acid; 3) probucol; 4) inhibitors of HMG CoA reductase. The drugs of the last group appear to be effective and safe in short-term experiments, but long-term studies are necessary to confirm their validity. A dietary approach, consisting in a strictly vegetarian soy diet, very rich in polyand monounsaturates fatty acids, has been recently tested by the author, with very promising results.

    Notes: Abstract In this paper we investigate the hyperfine structure and isotope shift of four near infrared xenon transitions by means of a semiconductor diode laser. Doppler free spectra were obtained by using either a saturation spectroscopy technique in cell or a laser induced fluorescence technique on a collimated atomic metastable beam. The hyperfine coupling constants of 129Xe and 131Xe were determined for the levels 1s5, 1s4, 1s42, 2p2, 2p4 and 2p6 (Paschen notation). Moreover, a systematic study of the isotope shift was performed for the 1s3 → 2p4 and 1s5 → 2p6 transitions for which all the stable isotopes 128–131Xe , 132Xe, 134Xe, and 136Xe were fully resolved.

    Notes: Abstract: High resolution infrared spectra (0.001 cm-1) have been measured for mixtures of 1-chloro-1,1-difluoroethane in Ne, expanded in a supersonic planar jet. The ν 7 fundamental has been analyzed for both isotopic species, CH3CF2 35Cl and CH3CF2 37Cl. A weak b-type component has been observed for the first time.
