Mild hemophilia A as a cause of bleeding in dermatologic surgery.

A 63-year-old male had major postoperative bleeding complications following the excision of a basal cell carcinoma. The patient denied a prior history of bleeding complications and had normal coagulation screening studies. After coagulation evaluation, he was found to have mild hemophilia A with 23% of normal Factor VIII C. We discuss an approach to the evaluation of coagulation in patients with perioperative and postoperative bleeding. Also, we outline treatment alternatives for patients with hemophilia A who need cutaneous surgery.

Estimation of the dynamic carotid flow in patients with normal radionuclide cerebral perfusion.

Radioisotope angioscintigraphy following intravenous injection bolus of 99mTc-pertechnetate was performed in 49 patients with cerebrovascular disturbances. The region of interest placement on the sequential analog images of both middle cerebral and internal carotid arteries and time-activity curves were displayed on the video monitor. In 35 cases of this group we have noticed symmetrical cerebral perfusion and a significant difference between right and left internal carotid flow, and in 33 cases of which dynamic studies were made stenosis or occlusion of the extracranial part of the carotid internal artery was revealed by the X-ray angiography.

Fully automatic computer-assisted pancreas imaging.

Good pancreas imaging is difficult to achieve even if a computer is applied. The special computer program proposed here was developed to optimize the results and to minimize the operator interaction with the data processing system.

A scintigraphic method of examining the patency of oviducts using 133Xe.

Described below is the radioisotope method of examining the patency of oviducts using a solution of 133Xe. Scintigraphic pictures of the uterine cavity and oviducts were obtained with a Jumbo Toshiba gamma-camera; they were subsequently analysed by an Informatek SIMIS-3 data processing system. A total of 30 women aged between 20 and 36 with primary or secondary infertility were examined. The patency of oviducts and the shape of the uterine cavity was assessed on the basis of: the overall picture of the activity of 133Xe in the uterine cavity and oviducts, the isocontours of the overall picture, curves of increasing and decreasing activity in the fallopian tubes, and the spatial picture of activity distribution in the uterus and fallopian tubes. The results of the examinations corresponded in all cases with the diagnosis made on the basis of hysterosalpingography. An advantage of the isotope method of examining the patency of fallopian tubes and the shape of the uterine cavity is the fact that it is an examination of a dynamic nature, completely safe for the patient and exposes the patients to a considerably lower dose of irradiation than during hysterosalpingography.

Chronoendocrinological studies in athletes. Circadian rhythms of T3, TSH, cortisol and testosterone.

Endocrine functions were studied in 83 healthy athletes, maintained under normal light-dark conditions, with normal activity-sleep patterns. In these subjects statistically significant circadian rhythms of T3, TSH, cortisol (CSL) and testosterone (T) were found; for each hormone two or three different types of circadian rhythm (with peaks of acrophase between: 6.30 a.m. and 1.30 a.m., 1.30 p.m. and 10.30 p.m., 10.30 p.m. and 6.30 p.m.) were observed. The following correlations have been demonstrated between the length of participation (in years) in performance sports and the mean circadian blood hormone concentration: a negative one for CSL (p less than 0.01) and a positive one for TSH (p less than 0.05). An increase of the mean circadian values of T concentration in venous blood was found in females fencers (n = 9).

Chronoendocrinological studies in athletes. Circadian rhythms of HGH and IRI.

The serum concentrations of HGH and IRI studied over a 24-hour span in 83 healthy athletes under normal rest conditions in a normal living environment show statistically significant rhythms, validated and quantified by cosinor analysis; for each hormone three different types of the circadian rhythm (with a peak of acrophase between: 6.30 a.m. and 1.30 p.m., 1.30 p.m. and 10.30 p.m., 10.30 p.m. and 6.30 a.m.) were observed. The IRI response to a meal load underwent cyclic variations during the day.

[Cerebral blood flow determination with the use of a Standard ZM 703 device].

The authors report a method of determination of regional blood flow in the brain with a Polish ZM 703 apparatus produced by United Nuclear Equipment Works POLON. The authors found that ZM 703 is useful for determination of brain blood flow but it should be equipped with detection crystals and collimators of smaller size for simultaneous examination of greater number of brain regions.
