Acromegaly with polycystic ovaries, hyperandrogenism, hirsutism, insulin resistance and acanthosis nigricans: a case report.

We describe a woman with acromegaly who had acanthosis nigricans and hirsutism. Serum growth hormone (GH) and testosterone levels were markedly elevated. Standard oral glucose tolerance test (OGTT) showed a diabetic curve and no suppressed GH levels. Fasting insulin levels were very high while plasma glucose levels were not hypoglycemic. Insulin tolerance test revealed blunted hypoglycemic response. Acanthosis nigricans was present in the right axilla and face. Ultrasonogram demonstrated bilateral polycystic changes in the ovaries. From the above findings this patient's condition is characteristic of a very rare syndrome consisting of acromegaly, polycystic ovaries (PCO), hyperandrogenism, hirsutism, insulin resistance and acanthosis nigricans.

[Comparison of HBsAg, anti-HCV and anti-HDV positivity in diverse groups].

Three hundred eighty three serum samples obtained from various patient groups and health care personnel were tested for HBsAg, Anti-HCV and Anti-HDV by ELISA technique. Anti-HCV antibodies were found 32.4% of chronic haemodialysis patients, 23% of the patients with chronic viral hepatitis and cirrhosis, 8.3% of health care personnel and less frequently detected in other groups. Anti-HDV antibodies were found 23% of the patients with chronic viral hepatitis and cirrhosis, 2.7% of blood donors, 8.1% of chronic haemodialysis patients and 1.3% of the patients who have malignancy. Anti-HDV antibodies were not detected in other groups.

[Asymptomatic bacteriuria in patients with diabetes mellitus].

The prevalence of asymptomatic bacteriuria and the relation of bacteriuria to pyuria, glycosuria and HbA1c in patients with diabetes mellitus were investigated. The study population included 110 diabetic patients and 100 healthy persons (control group). The ratio of bacteriuria was found as 25.5% (31.3% in women, 17.4% in men) in the diabetic group and as 9% (16% in women, 0% in men) in the control group. The prevalence of asymptomatic bacteriuria was significantly higher in the diabetic patients than in the control group (p less than 0.05). There was a significant relation between bacteriuria, pyuria and HbA1c levels (p less than 0.05). But, there wasn't any important correlation between bacteriuria and glycosuria.

Analysis of the severe complications of irradiation of carcinoma of the cervix: whole pelvis irradiation and intracavitary radium.

From January, 1967 to December, 1974, 325 patients with carcinoma of the uterine cervix were treated with a minimum of 4,000 rad whole pelvis irradiation plus intracavitary radium. These patients had large, sometimes massive, tumors. Generally, the larger the primary tumor the greater the amount of external irradiation delivered, with an appropriate reduction in the amount of intracavitary radium. Patients who had a positive lymphangiogram or a pre- or postirradiation hysterectomy or lymphadenectomy are not included in this analysis. All patients were followed for a minimum of 5 years. Local and regional failure rate in 193 patients receiving 4,000 rad whole pelvis irradiation plus radium was 1% and 4%, respectively, with a 3.1% incidence of severe complications. In 111 patients who received 5,000 rad whole pelvis irradiation plus radium, the local and regional failure rate was 3.5% and 4.5%, respectively, with a 10% incidence of severe complications. In patients who received 5,000 rad whole pelvis irradiation, complications were associated with unilateral parametrial boosts and with protruding vaginal sources. Of 21 patients who received 6,000 rad whole pelvis irradiation, three patients developed fistulae associated with high doses to the vagina delivered with protruding vaginal sources.

A comparative study of two preoperative radiation regimens with cystectomy for bladder cancer.

This report surveys the results of two programs of preoperative irradiation with radical cystectomy for bladder cancer in 205 patients. Irradiating the true pelvis to 4000 rads in 4 weeks with radical cystectomy after 6 weeks was implemented in 119 patients (Group 1) from 1959 to 1965; 2000 rads given in 1 week to the true pelvis and radical cystectomy within the following week was implemented in 86 patients (Group 2) from 1966 to 1970. Determinate survival without evidence of recurrence at 5 years was 43% in Group 1 and 42% in Group 2. Mortality with recurrence of bladder cancer in 5 or more years was 44% in group 1 and 42% in group 2. Pelvic complications occurred in 13% of group 1 and 9% of group 2.

The alteration on serum thyroid hormones and iodine levels when the 10% povidone iodine solution was topically performed on ano-rectal mucosa.

In this experiment, the 10% povidone-iodine (PI) solution was topically administered on ano-rectal mucosa by enema and its effects on thyroid hormones and iodine levels in serum were examined in rabbits. The solution was given in a volume of 20 ml daily for three days. Blood samples were drawn at 1st, 4th and 7th days after the first enema. The serum iodine levels reached maximum values at the first day was still elevated at the 4th and 7th days, but T3, T4 and TSH values remained within the normal limits. Iodine did not produce alterations in the levels of thyroid hormones and TSH, although it is known that a considerable amount of it is absorbed from the intestinal lumen.
