Data of 22,691 observations on parturition related problems (dystocia, calf mortality, milk fever, retained placenta, and mastitis) were collected from 27 cooperating California dairy herds. Age at first calving did not affect calving difficulty; thus, an optimal age for first calving was not identified. Decisions on breeding virgin heifers should ...

Replantation surgery offers a rewarding challenge for one to apply basic biologic and functional concepts to deal with an infinite variety of amputation problems. Although there is an obvious requirement for technical skill, there is no place for stereotype procedures. Often the exact plan of treatment cannot be determined until ...

Problems of sexual dysfunction were surveyed by questionnaire mailed to women who had undergone rectal resection and ostomy surgery over a ten-year period. Completed questionnaires were returned by 30 respondents, 19 to 54 years of age, who indicated both physical and psychological problems. Many of the problems were solved by ...

Questionnaire cards were sent to 45,000 family shoe store customers; 15,000 cards were completed and returned, thereby permitting a broad statistical base in respect to the incidence and types of foot problems encountered in the United States. The incidence of corns, calluses, warts, ingrown toenails, bunions, hallux rigidus, hammer toes, ...

Hemostasis remains a major technical problem in surgery of the liver and spleen. A high power neodymium-doped yttrium aluminum garnet (Nd:YAG) laser has been coupled with a fiberoptic delivery system and quartz blade designed to yield maximal hemostasis and minimal tissue injury. In a series of experiments we were unable ...

Paternalism--coercive or deceptive interference in a citizen's life for his own good--is much in evidence in our policies regarding the aged. Some argue that paternalism is an unwarranted denial of individual liberty, ,for doubtful societal gain. Others contend that freedom has but instrumental value, and the aged cannot always use ...

It is proved that the emptiness problem for deterministic bottom-up triangle acceptors (BTA's) over a single input symbol is recursively unsolvable. From this result, it is also shown that certain decision problems involving BTA's and BPA's (deterministic bottom-up pyramid acceptors) are unsolvable.

The anterior capsular mechanism appears to be the common denominator in a number of shoulder problems ranging from the recurrent dislocation ("too loose") to the frozen shoulder ("too tight"). The shoulder region and the anterior capsular mechanism can be carefully and accurately assessed by arthrography and cineradiography. Bicipital tenosynovitis has ...

In this first part of a two-part paper we introduce a general consistent labeling problem based on a unit constraint relation T containing N-tuples of units which constrain one another, and a compatibility relation R containing N-tuples of unit-label pairs specifying which N-tuples of units are compatible with which N-tuples ...

Arthroscopy of the knee is an essential diagnostic aid for difficult knee problems. It is safe and is indicated especially in the problem knee of adolescents, where it is most undesirable to remove a normal cartilage; in litigation cases; in the post-surgery knee problem; in planning surgical procedures; and in ...

Various methods of surgical correction of lid retraction are discussed. Retraction secondary to overcorrected ptosis surgery is more amenable to correction by various stretching techniques, incising of the levator or recession of the lid elevators. Endocrine lid retraction poses a more difficult problem. Because of the many facets to the ...

It is difficult to truly define iatrogenic complications in the postsurgical state in that the surgery is a condition originated by physician intervention and thus any problems that occur may be technically considered as physician created. In this article we attempt to demonstrate problems that occur both due to technical ...

Experience with the routine use of the pharmacologically aided, double-contrast examination to demonstrate various primary and healing ulcers over a six month period is assessed. Thirteen linear or rod-shaped ulcerations were diagnosed. It appears that gastric relaxation and the demonstration of fine mucosal relief are necessary to detect ulcers of ...

In cases in which renal repair through conventional in situ surgery is not possible, we have proceeded to remove the organ outside of the human body and placed in on a work bench where exsitu repair is aided by microsurgery, x-ray films, and image amplifiers. In most cases the damaged ...

The numerically important mental disorders found in the senescent population are reviewed from the point of view of their relationship to the process of ageing. Only two direct relationships are seen: the acute confusional states due to the age-linked decline in stress resistance; and the neurotic reactions due to the ...

Although counselling and preoperative siting of the stoma help to eliminate problems following stomal surgery, certain problems may still arise, often when the patient has returned home. Early recognition of these problems and intervention can help to maintain a good quality of life for patients and prevent the condition worsening.

According to statistical reports, venereal disease case-rates and death-rates have both shown a real decline in Japan in the last decade. However, from a one-day survey of patients in all Japanese medical establishments carried out in 1955, it is estimated that not less than 720 000 new cases of venereal ...
