[A case of peripelvic extravasation related to pregnancy].

A 35-year-old woman was hospitalized at 39 weeks 0 days of gestation because of acute left flank pain. Magnetic resonance imaging (MRI) revealed bilateral hydronephrosis with peripelvic extravasation of contrast material around the left kidney. The pregnancy ended with a cesarean section and after the cesarean section a left double-J-stent was placed cystoscopically. An excretory urogram following the removal of the ureteral stent showed no extravasation or hydronephrosis in either kidney.

Clinical evaluation of prophylactic intranasal 1-phenyl-3-(4-phenyl-2-thiazolyl) guanidine (CL 88,277) medication against rhinovirus 44 challenge.

The prophylactic intranasal medication with a new antiviral compound, 1-phenyl-3-(4 phenyl-2-thiazolyl) guanidine (CL 88,277) was evaluated in humans against rhinovirus 44 challenge. One ml containing 250 mg of CL 88,277 was administered to 10 seronegative volunteers three times a day plus one dose prior to the rhinovirus challenge (32 TCID 50) and for six consecutive post-challenge days. Ten other subjects received 56% polyethylene glycol (PEG-400), the solvent of CL 88,277 at the same time. Five subjects in each of the CL 88,277-treated and placebo-treated groups developed illness. There were no differences between the two groups in the occurrence of the severe illness and of the moderate and severe illnesses. Each sign and symptom occurred almost equally in the two groups and there was no difference in their scores between the two groups. The challenge virus was isolated from both groups but the total number of the virus isolates was less and the time span of virus excretion was shorter for the drug-treated group. The post-challenge serum antibody titers were markedly lower in the drug-treated group. Prophylactic intranasal CL 88,277 medication did not affect the course of illness induced by rhinovirus 44 challenge. It appears, however, that the virus replication in the nose was reduced and as a result the serum antibody response was diminished. PEG-400 caused a transient irritation of the nasal mucosa in all recipients.

Clinical and serologic effects of live attenuated serum inhibitor-resistant influenza B vaccine in seronegative adults.

The clinical effects, nasal and serum antibody responses, and virus excretion of a live attenuated serum inhibitor-resistant influenza B virus vaccine, R75, was evaluated in 43 seronegative healthy adults by a random double-blind study. Symptom responses were minimal and were not significantly different between vaccine and placebo groups. No fevers, abnormalities in physical examination or laboratory testing developed during 4 weeks of observation. Among vaccinees, 10 (48%) developed serum hemagglutination-inhibition (HI) antibodies, 16 (76%) developed serum neutralization (N) antibodies and 4 (19%) developed nasal N antibodies. The GMT responses from study day 0 to day 28 were 4.0 to 10.4 for serum HI, 1.8 to 9.8 for serum N, and 1.0 to 1.4 for nasal N. There were no significant titer changes in the placebo group. No virus excretion was detected. Although there are some questions concerning the relationship of antibody levels to protection, the low antibody responses in this study are an indication that R75 is not sufficiently immunogenic.

The effects of intramyometrial injection of prostaglandin F2alpha on severe post-partum hemorrhage.

Effectiveness of prostaglandin F2alpha (PGF2alpha) in controlling postpartum uterine hemorrhage was evaluated with the following results. (1) Systemic administration, whether by continuous i.v. infusion or by gluteal i.m. injection, was not a completely adequate method for hemostasis. (2) Local administration by directly injecting into the uterine musculature, whether transabdominally or transvaginally, resulted in a dramatic reduction of the rate of bleeding. Routine clinical application of the direct intramyometrial injection of PGF2alpha for severe post-partum hemorrhage is recommended in view of its easy performance, excellent hemostatic effect, minimal side effects and good prognosis.

Double-blind clinical assessment of ribavirin (virazole) in the prevention of induced infection with type B influenza virus.

The prophylactic effectiveness of oral administration of ribavirin (1-beta-D-ribofuranosyl-1,24-triazole-3-carboxamide, virazole) against artificially induced influenza B infection was evaluated in a double-blind clinical trial. Fifteen seronegative men received ribavirin capsules (600 mg/day in three divided doses), and 15 other men received placebo capsules two days before the inoculation of 6.4 X 10(4) 50% tissue culture infective doses of influenza virus B/Georgia/26/74 and for eight days after challenge. Ten men (69%) in each of the two groups developed mild to severe influenzal illness. Of these, five placebo-treated men developed severe febrile illness, while only one drug-treated man had illness of comparable severity. Illness of moderate severity was observed in three placebo-treated conrols and two drug recipients. There was no difference between the frequencies of isolation of virus or the anitbody responses in the two groups. Ribavirin suppressed signs and symptoms induced by influenza B challenge, but its effectiveness was marginal.

Comparative clinical and laboratory evaluation of the prophylactic capacity of ribavirin, amantadine hydrochloride, and placebo in induced human influenza type A.

The comparative prophylactic effectiveness of oral treatment with ribavirin (1-beta-D-ribofuranosyl-1,2,4,triazole-3-carboxamide; virazole) and amantadine hydrochloride against artificially induced infection with influenza A virus was evaluated in 29 seronegative men who received ribavirin capsules (200 mg) three times daily, placebo capsules three times daily, or amantadine capsules (100 mg) twice daily. Medication was started two days before the inoculation of 2 X 10(4) 50% tissue culture infective doses of A University of Maryland/2/74 (H3N2) influenza virus and was continued for eight days after challege. Nine of the 10 subjects who received ribavirin, eight of the nine subjects who received placebo, and six of the 10 subjects who received amantadine developed influenzal illness. Significantly less virus was isolated from the amantadine-treated group than from the placebo-treated or the ribavirin-treated group. Antibody responses of the ribavirin-treated and placebo-treated groups were quite similar to each other; however, prophylactic treatment with amantadine significantly reduced titers of serum antibody and febrile responses. In a separate clinical trial involving challenge with A/Dunedin/73 (H3N2) influenza virus, ribavirin also failed to show prophylactic effectiveness.

Clinical and serologic effects of Alice strain live attenuated influenza A (H3N2) virus vaccine in an adult population.

Alice strain live attenuated influenza A (H3N2) virus was evaluated in prison volunteers. By random double blind allocation, 94 volunteers received Alice strain vaccine (AS) intranasally and 97 received placebo. The vaccine was well tolerated, and there was no serious morbidity. The number, type, duration, and severity of symptoms was not significantly different between the vaccine and placebo groups. Seventy-five per cent of vaccines with initial HAI titers less than or equal to 1:8 had 4 fold or greater titer responses on day 30. Placebo recipients experienced no titer changes. The GMT among vaccinees increased from 23.5 prior to vaccination 59.7 30 days later. Surveillance activities failed to document influenza A (H3N2) infection in the volunteer population during a 6 month follow-up period. Additional studies on the protective effects of the vaccine are required before efficacy can be determined.
