Esophageal carcinoma presenting as a primary renal tumor.

A patient with esophageal carcinoma presenting with hematuria is described. Initial studies confirmed the presence of a renal mass that was thought to be a primary renal neoplasm. Further studies to evaluate anemia before a renal operation led to the discovery of an unsuspected esophageal carcinoma. Although metastases to the kidneys are relatively common it is uncommon for these lesions to be clinically apparent or responsible for producing initial symptomatology. Only after discovery of the esophageal lesion was the possibility of a secondary renal neoplasm considered. Intractable hematuria was treated successfully by embolizing the renal artery of the bleeding kidney with gelatin sponge fragments.

Genital herpes simplex virus (HSV) isolation during pregnancy.

Eight patients with laboratory-confirmed herpes simplex virus (HSV) infection were cultured repeatedly during their pregnancies. Two of the 8 patients did not have typical HSV lesions. All patients became culture negative and all delivered normal infants vaginally. Because asymptomatic women can transmit HSV to neonates at parturition, it is important to do viral cultures as well as to clinically assess the mother.

Localized herpes simplex infections in atopic dermatitis.

Herpes simplex infections, localized to areas of atopic dermatitis, were documented in ten children. The typical clinical picture consisted of low-grade fever and exacerbation of the eczema with discrete vesicles localized to affected skin, followed by punched-out ulcerations. Recurrent attacks were observed in seven cases and coincided with active attacks of herpes labialis in other family members or close friends, suggesting reinfection as the source. In no patient did a disseminated Kaposi's varicelliform type of eruption develop. Viral cultures in 30 additional patients with acute flares of atopic dermatitis without vesicles or ulcerations failed to disclose any herpes simplex.

Herpes simplex virus type 2 infection of neonatal mice.

We have demonstrated that newborn mice can be infected orally with herpes simplex virus type 2. Transplacental and transvaginal transmission of herpes simplex virus type 2 did not occur in our mice. Failure to produce natural transvaginal infection in mice may be explained by the relatively short period of exposure to the virus during parturition. These experiments demonstrate that high oral doses of herpes simplex virus type 2 can produce disseminate herpes neonatal infection in mice and therefore may be useful in future investigations into the mechanism and the treatment of this disease.

Assessment of ovarian function in perimenopausal women after stopping oral contraceptives.

Ovarian function was assessed by measuring plasma gonadotrophins, urinary oestrogen and urinary pregnanediol levels, every week for four weeks, in 34 women, aged 45 to 57 years, after withdrawal of oral contraceptive therapy. A rise in urinary pregnanediol excretion occurred in 14 patients suggesting that ovulation had occurred and that these patients were "premenopausal". Elevated serum gonadotrophin values and persistently low urinary oestrogen and pregnanediol excretion occurred in 13 patients suggesting ovarian failure or a "postmenopausal" state. However, one apparently "postmenopausal" patient later showed hormonal evidence of ovulation, indicating fluctuation in ovarian function. There were 7 patients with "indeterminate" hormone profiles whose ovarian function was difficult to assess. All patients excreting more than 45 nmol of oestrogen a day had a spontaneous period within 45 days of stopping hormone therapy.

Pseudocysts: diagnosis in the adult by total body opacification.

Recent use of higher doses of contrast material for excretory urography in adults has made differentiation between cystic and solid masses feasible in adults just as it has been in children. The first two adults to have the cystic nature of their pseudocysts ascertained by total body opacification are presented. In one case, the mass was not palpable because the abdomen was markedly tender, suggesting that total body opacification may be helpful in the examination of the acute abdomen. The second case suggests the importance of the prone position.

A methodology for the production of carbohydrate-specific antibody.

8-Methoxycarbonyloctyl glycosides are recommended as precursors for the preparation of artificial antigens that possess strongly immunodominant carbohydrate antigenic determinants. The preparation and immunochemical properties of a selected number of these antigens are reported to demonstrate the high levels of hapten-specific antibodies that are normally achieved using standard immunization schedules. The method, based on glycoside synthesis, promises to make available a wide spectrum of well defined antigens and the homologous antibodies.

Visualization of the gallbladder wall at excretory urography: implication for infusion tomography of the gallbladder.

Visualization of the gallbladder wall during intravenous infusion of diatrizoate has been equated with cholecystopathy. However, a large control group of patients without biliary tract symptoms has not been studied. The authors examined a group of 2,867 such patients who underwent excretory urography; the results suggest that visualization of the normal gallbladder wall occurs frequently enough to severely limit the usefulness of infusion tomography of the gallbladder in the diagnosis of cholecystopathy.

Hepatic abscess. Diagnosis in the adult by total body opacification.

Two adults had the hypovascular nature of their hepatic abscesses ascertained by total body opacification. In one, total body opacification identified the hypovascular nature of the lesion, facilitating its differentiation from vascular hepatoma. In the other, the clinical diagnosis was acute cholecystitis with empyema of the gallbladder, and the liver was normal to inspection and palpation at celiotomy. Total body opacification may be helpful in the examination of abdominal masses.
