Benign, noninvasive epithelium versus invasive carcinoma Gallbladder adenocarcinomas may be deceptively bland appearing and, as such, may be difficult to distinguish from Aschoff-Rokitansky sinuses or Luschka s ducts. Although p53 and Ki-67 are significantly more common in neoplastic epithelium, overlaps are unfortunately too common for them to have a conclusive role in this distinction. Similarly, dense cytoplasmic expression of MUC1 and CEA is more characteristic of invasive adenocarcinomas. Unfortunately, this feature is not as evident in the more problematic well-differentiated carcinomas, in which the expression is more typically luminal membranous. 

Yet another improvement was of great influence on the economics of yeast production The separation of the yeast from the spent mash was performed by centrifugation and subsequent dehydration of the resulting yeast cream in a frame press. Only the application of frame presses allowed dry substance values of about 27% to be attained, this being the desired standard with respect to handling properties and shelf-life. Attempts to replace frame presses with rotating drum filters showed that such dry substance values were barely achievable. The problem was solved in an ingenious way by K. v. Rokitansky and E. Rustier.

In the vast majority (88%), dermoid cysts are uni-lociflar cystic lesions filled with sebaceous material. A protuberance, the Rokitansky nodule, or dermoid plug, projects into the cavity and is the hallmark of dermoids (Fig. 9.17). It contains a variety of tissues, often including fat and calcifications, which represent teeth or abortive bone. Fat is detected in over 90%,... 

A minority of dermoid cysts will demonstrate no fat or only small foci of fat within the wall or the Rokitansky nodule (Fig. 9.28) [73]. Yamashita et al. reported that 15% of mature teratomas did not show fat within the cystic cavity. Approximately half of these cases displayed small amounts of fat within the wall of the dermoid or the dermoid plug. In 8% of henign teratomas, no fat could be detected [73]. 

Mayer-Rokitansky-Kuster-Hauser syndrome is a combined anomaly that belongs to this entity The typical form of this syndrome is characterized by congenital absence of the uterus and upper vagina. The ovaries and fallopian tubes are usually normal. The atypical form of the syndrome includes associated abnormalities of the ovaries and fallopian tubes and renal anomalies [32] (Fig. 16.16).

Karl Rokitansky (1804-1878) dissected more than 30,000 cadavers in his lifetime. Although he is best remembered for his studies of defects in the septum of the heart, he was the first to describe acute dilatation of the stomach. In addition, he was of the opinion that ulcer disease was due to abnormal function of the vagus nerve. Apart from his brilliance, and despite the fact that he was a pathologist, Rokitansky was a man possessed of considerable wit. Thus, of his four sons, two of whom were physicians and two singers, he said D/e Einen heilen, die Anderen heulen. (One group heals, the other howls.)...

Mayer-Rokitansky-Kiister-Hauser syndrome characterized by the absence of the entire vagina or, more commonly, the proximal two-thirds of the vagina absence or abnormalities of the uterus and malformations of the upper urinary tract (Fig. 7.5). 

It affects 1 in 4,000-5,000 otherwise normal (46 XX) girls. Mayer-Rokitansky-Kiister-Hauser syndrome type A (typical form) shows normal-appearing external genitalia, absence of the vagina and uterus, normal fallopian tubes, normal ovaries, and no renal anomalies. In type B (atypical form), the uterus may be normal except for the lack of a conduit to the introitus or may be rudimentary, commonly show-... 

The typical patient seeks medical advice at the expected time of onset of puberty because of primary amenorrhea. Upon physical examination the external genitalia are those of a normal female, although the introitus may end in a shallow blind pouch. Depending on whether there is a functional endometrium, cyclic or intermittent abdominal pain may be present due to hematocolpos or hematome-trocolpos. Mayer-Rokitansky-Kuster-Hauser syndrome is the second most frequent cause of primary amenorrhea after the classic Turner syndrome. 

As a rule, the ozone-oxygen mixture is employed in cases of arterial circulatoiy disturbances. This method was first described by Dr. Lacoste in 1951 and since then has attracted the attention of many scientists. Rokitansky [207] was the first who made a statistical evaluation, according to which four out of ten patients with arterial-metabolic circulatory disturbances treated with ozone did not need operation the results of other authors confirm his conclusions [208, 209].
