Central venous silicone elastomer catheter placement by basilic vein cutdown in neonates.

There is a need for central venous access in small premature infants and other neonates when enteral feeding is not tolerated or is contraindicated. We placed 83 small (0.635-mm od) silicone elastomer catheters by basilic vein cutdown through a subcutaneous tunnel in 79 patients during a 12-month period. Thirty-five patients (44%) weighed less than 1,000 g. Each patient on whom the procedure was attempted had successful placement of a catheter, and they remained in place a mean of 20 days (range three to 82). Patients had a mean weight gain of 15 g per day of catheter use. Sixty-two catheters (75%) were removed electively, 13 (16%) secondary to complications, six (7%) because of patient deaths (none catheter related), and two (2%) were accidentally dislodged. Two episodes of catheter-related sepsis (0.12 episodes per 100 days of catheter use) caused by Candida albicans and Staphylococcus epidermidis were encountered. Other complications included one subclavian vein thrombosis, eight catheter occlusions, and two local arm inflammations. This technique proved to be a safe, easy, and inexpensive method to administer parenteral nutrition to neonates, especially those weighing less than 1,000 g.

Spastic striated external sphincter syndrome imitating recurrent urinary tract infection in females. Effect of long-term alpha-adrenergic blockade with phenoxybenzamine.

6 women with spastic striated external sphincter syndrome were studied urodynamically and subsequently treated with an alpha-adrenoceptor-blocking agent. Symptoms were abolished, and prolonged, fluctuating flow curves were nearly normalized by phenoxybenzamine, 15 mg daily, in 5 of 6 patients despite the unchanged spasticity of the external striated urethral sphincter.

Interferon therapy in neoplastic disease. A preliminary report.

The treatment of 10 patients having neoplastic disease with exogenous i.m. interferon therapy is described. The interferon given is partially purified interferon produced from human leukocytes. Sendai virus is used as interferon inductor. The patients reported in this paper have been on treatment for periods of 2-28 months. Apart from initial periods of fever, no side-effects have been recorded. Patients suffering from bladder papillomas have shown partial regression after a few months of therapy. The other cases treated are too few to warrant any conclusions, but the therapy does seem to have been beneficial.

Spontaneous non-aneurysmal rupture of the renal pedicle artery due to acute vasculitis in polyartheritis nodosa--with survival.

The first published case is presented of survival following a ruptured renal artery due to acute vasculitis in polyarteritis nodosa (PAN). Spontaneous, massive retroperitoneal hemorrhage was the presenting symptom in this case. Emergency nephrectmoy was carried out as a life-saving procedure. Postoperative studies revealed that only the kidneys and joints were involved in the disease.

Hepato-biliary scintigraphy and hepatography with Tc-99m diethyl-acetanilido-iminodiacetate in obstructive jaundice.

Tc-99m diethyl-IDA was used for combined serial hepato-biliary scintigraphy and processing of hepatographic curves, using a scintillation camera and an image-processing system. Patients with obstruction of the common bile duct, proven by operation, were investigated. Hepatograms from an area of interest corresponding to the periphery of the right liver lobe varied predictably with changes in the serum levels of alkaline phosphatase and bilirubin. Both anatomical and functional information was obtained. The investigation could be carried out even under reduced liver function. Hepatic uptake of the agent was noted at serum alkaline phosphatase levels up to 1000 U/l and serum bilirubin levels up to 170 mumol/l.

Fine needle and open biopsy in thyroid disorders.

The diagnostic value of cytological, serological and scintigraphical examination was evaluated in 20 histologically verified cases of thyroid disorder. The predictive values of specificity as to malignancy, thyroiditis and thyroid autoantibodies were respectively 0 percent (0-71), 80 percent (28-99) and 75 percent (19-99), and the predictive values of sensitivity were 88 percent (64-99), 100 percent (78-100) and 94 percent (70-100). Cold nodules were malignant in 40 percent. Fine needle biopsy can be used as a supplementary test without any risks and is a valuable aid in the diagnosis of Hashimoto's thyroiditis, but not in the diagnosis of malignant lesions. If any clinical or scintigraphical (cold nodule) suspicion of malignancy exists, a surgical biopsy must be done.
