Phenotypic Males With 46, Xx Karyotype: Report Of Two New Cases, G. R. Rubio, Lester Weiss, J. F. Nunez, M. Saeed Uz Zafar Mar 1974

Phenotypic Males With 46, Xx Karyotype: Report Of Two New Cases, G. R. Rubio, Lester Weiss, J. F. Nunez, M. Saeed Uz Zafar

Henry Ford Hospital Medical Journal

Two sex chromatin positive phenotypic males were found to have 46, XX karyotypes. Both had small testes and elevated gonadotropins with low testosterone levels. Semen analysis could not be obtained but one man claimed to have a daughter. In one patient, mosaicism was suggested by the finding in a single cell of a chromosome morphologically resembling a Y. A second cell line was not found in the other patient. Possible explanations for the development of a male phenotype in the absence of demonstrable Y chromosome include the existence of two cell lines or mosaicism, an autosomal sex determining gene and …

Removal Of An Intra-Abdominal French Catheter Through The Laparoscope, Asghar Afsari Mar 1974

Removal Of An Intra-Abdominal French Catheter Through The Laparoscope, Asghar Afsari

Henry Ford Hospital Medical Journal

Use of refined instruments for the removal of an intra-abdominal foreign body has enhanced the indication for operative laparoscopy. In particular instances, laparoscopy has proven more advantageous than laparotomy. This case report illustrates removal of an intra-abdominal rubber catheter via a laparoscopic procedure with a double puncture technique.

Correction Of D-Loop, D-Transposition Of The Great Arteries And Sub-Pulmonary Stenosis With A Dacron Conduit And Stented Porcine Xenograft Valve, Lorenzo Gonzalez-Lavin, Gordon M. Folger Mar 1974

Correction Of D-Loop, D-Transposition Of The Great Arteries And Sub-Pulmonary Stenosis With A Dacron Conduit And Stented Porcine Xenograft Valve, Lorenzo Gonzalez-Lavin, Gordon M. Folger

Henry Ford Hospital Medical Journal

Total correction of transposition of the great arteries and left ventricular outflow tract obstruction has become feasible in recent years. Certain modifications are needed, however, to improve the long term function of the valved conduit required in the procedure. A stented porcine xenograft valve, sutured into a woven Dacron tubular graft, was used successfully in the total correction of such a malfunction. The patient described is the first so treated at the Henry Ford Hospital. The main advantage of this technique is its practicality. Both Dacron tubular grafts and stented porcine xenograft valves are commercially available. This approach is applicable …

Position-Dependent Pleural Friction Rub, Thomas L. Connolly Mar 1974

Position-Dependent Pleural Friction Rub, Thomas L. Connolly

Henry Ford Hospital Medical Journal

The art of physical examination is often forgotten by clinicians in their haste to depend on laboratory tests. This paper described a helpful way to diagnose pleurisy in someone who should have it according to the history. Auscultation of the chest in the supine and lateral decubitus positions will occasionally facilitate the detection of a pleural friction rub when conventional examinations may not do so. Two patients are described in whom this method was used.

Greenhouse Fungicide — Environmental Carcinogen?, Marvin D. Anderson, Herbert S. Rosenkranz Mar 1974

Greenhouse Fungicide — Environmental Carcinogen?, Marvin D. Anderson, Herbert S. Rosenkranz

Henry Ford Hospital Medical Journal

A simple screening method, in which a bacterial mutant deficient in its ability to repair DNA, was used to detect genetic damage from a widely-used fungicide. The finding strengthens the suspicion that it may be a potent human carcinogen. The unique role of the physician in eliciting a history of exposure from a patient with cancer is emphasized in the case report.

Physicians And Surgeons--The Expanding Role Of The Physician's Assistant, Joseph S. Beeson Feb 1974

Physicians And Surgeons--The Expanding Role Of The Physician's Assistant, Joseph S. Beeson

West Virginia Law Review

The shortage of health care professionals in West Virginia today is a matter of grave concern, especially to inhabitants of rural areas where professional medical care is often nonexistent. Statistics are indicative of the problem, but do not reveal the entire picture. For example, in the United States today, there are approximately 171 physicians per 100,000 population. In West Virginia, each 100,000 persons is served by only 111 physicians. This figure alone is cause enough for concern, but the seriousness of the situation is more accurately indicated by the distribution of the physician population. West Virginia is primarily a rural …

Surgical Treatment Of The Upper Extremity In Rheumatoid Arthritis, Charles L. Mcdowell Jan 1974

Surgical Treatment Of The Upper Extremity In Rheumatoid Arthritis, Charles L. Mcdowell

MCV/Q, Medical College of Virginia Quarterly

All surgical procedures designed to preserve or improve function in the extremities, whether in rheumatoid arthritis or not, must consider the functional emphasis of the upper extremity as compared to the lower extremity. The upper extremity has, as its primary goal, mobility and prehension, whereas in the lower extremity, stability is the most important goal, mobility the next in order of importance, and prehension the least important. For example, the feet fulfill a need for stability with very little requirement for prehension, but the hand is more an instrument for prehension and there is less need to consider stability. I …

Viruses And The Conntective Tissue Diseases, Morris Ziff Jan 1974

Viruses And The Conntective Tissue Diseases, Morris Ziff

MCV/Q, Medical College of Virginia Quarterly

A number of observations in the last few years have attracted attention to the possibility of viral infection in systemic lupus erythematosus (SLE). One of these is the occurrence of interwoven tubular structures, usually in the endothelial cells of the kidney but also in the lymphocytes and in fibroblasts when SLE skin fibroblasts are cultured. These tubular structures have resembled viruses (they were thought by their discoverers to be myxo- or paramyxoviruses), but it has been argued that they are not viruses because of their size and appearance and because they have been produced in tissue cultures from subjects who …

The "Three R'S" Of Delayed Hypersensitivity, David Horwitz Jan 1974

The "Three R'S" Of Delayed Hypersensitivity, David Horwitz

MCV/Q, Medical College of Virginia Quarterly

Delayed hypersensitivity is one of several immune responses initiated by thymus-derived (T) lymphocytes. The mononuclear infiltrate of delayed hypersensitivity is a collaborative phenomenon between T lymphocytes and monocytes. This collaboration can be separated into components which I have chosen to call the "three R's" of delayed hypersensitivity. In this discussion I will define these "three R's" and examine the usefulness of this concept in clinical medicine.

Arteriography Of Cerebrovascular Disease, Frederick S. Vines Jan 1974

Arteriography Of Cerebrovascular Disease, Frederick S. Vines

MCV/Q, Medical College of Virginia Quarterly

The importance of complete angiographic studies in patients suspected of extracranial vascular disease has been emphasized. Examples of a variety of lesions of the intracranial and extracranial circulation have been shown. It is important that the angiographer obtain adequate visualization of the circulation cephalad to the aortic arch with awareness of the type of lesion and technical problems that may be encountered. It is only in this way that further understanding of the "stroke syndrome" can be attained with appropriate therapy.

The Neuro-Ophthalmology Of Cerebrovascular Disease, John W. Harbison Jan 1974

The Neuro-Ophthalmology Of Cerebrovascular Disease, John W. Harbison

MCV/Q, Medical College of Virginia Quarterly

The neuro-ophthalmology of cerebrovascular disease is a vast plain of neuro-ophthalmic vistas, encompassing virtually all areas of disturbances of the eye-brain mechanism. This paper will be restricted to those areas of the neuro-ophthalmology of cerebrovascular disease which one might consider advances in its clinical diagnosis and treatment.

Advances In The Surgical Treatment Of Patients With Extracranial Cerebral Vascular Disease, Thoralf M. Sundt Jr. Jan 1974

Advances In The Surgical Treatment Of Patients With Extracranial Cerebral Vascular Disease, Thoralf M. Sundt Jr.

MCV/Q, Medical College of Virginia Quarterly

Since the subject of surgery for carotid artery occlusive disease is too broad to be covered in its entirety, we will dwell primarily on some results of cerebral blood flow measurements and electroencephalograms performed during this procedure, their meaning and relationship to states of cerebral ischemia, and some controversial aspects of the surgery. An understanding of cerebral hemodynamics and the tolerance of neural tissue to ischemia is of major importance to any surgeon or physician dealing with this illness.

Continuous Intracranial Pressure Monitoring In Patients With Brain Injury: Technique And Application, John K. Vries Jan 1974

Continuous Intracranial Pressure Monitoring In Patients With Brain Injury: Technique And Application, John K. Vries

MCV/Q, Medical College of Virginia Quarterly

Continuous ICP monitoring using the hollow screw technique has proven itself simple, safe, and reliable. The obvious advantage of continuous ICP monitoring is to provide early warning of developing mass lesions before clinical signs appear and to assess the effectiveness of therapy directed at brain edema. Its most important use, however, may be that it permits the use of depressant medications in these patients. Many of these patients have a marked tendency toward hyperthermia, severe hyperventilation, and erratic blood pressure swings. These tendencies can be most difficult to control with conventional treatment regimens. By sedating these patients, however, it is …

Practical Anticonvulasant Pharmacokinetics, R.B. David, L.K. Garrettson Jan 1974

Practical Anticonvulasant Pharmacokinetics, R.B. David, L.K. Garrettson

MCV/Q, Medical College of Virginia Quarterly

Pharmacokinetics is that area of pharmacology concerned with the absorption, distribution, metabolism, and elimination of drugs. The processes by which absorption, distribution, and elimination take place are referred to as unit processes. These occur independently and concurrently, and involve such activities as absorption into the blood, elimination from the blood, distribution between the blood and tissue, inactivation in tissues, and finally, elimination from the blood. Drug handling by the body can be characterized by the rate for each step or, more often, the rate of all processes. Classification of observed kinetics for these rate processes includes first-order, zero-order, and capacity-limited …

Radical Reconstruction Of Complex Cranio-Orbito-Facial Abnormalities, John A. Jane, Milton T. Edgerton Jan 1974

Radical Reconstruction Of Complex Cranio-Orbito-Facial Abnormalities, John A. Jane, Milton T. Edgerton

MCV/Q, Medical College of Virginia Quarterly

Excellent cosmetic results can be obtained by early intervention in severe cranial-orbital-facial deformity. This intervention should take the form of a combined intracranial and extracranial approach. While the procedure is of great magnitude, the benefits to the patient and to the family seem worth the risk.

Surgical Care Of The Lower Extremity In Rheumatoid Arthritis, Roby C. Thompson Jan 1974

Surgical Care Of The Lower Extremity In Rheumatoid Arthritis, Roby C. Thompson

MCV/Q, Medical College of Virginia Quarterly

One of the most important things for the physician to recognize in referring a patient to the orthopedic surgeon for treatment of rheumatoid arthritis is the goal of surgical correction. The primary goal in surgical treatment of diseased joints in the lower extremity is relief of pain. Some pain-free patients have such severe deformities that a surgical procedure may be undertaken in order to improve and restore function, accepting certain calculated risks; however, to improve function surgically in a pain-free joint requires complete and full understanding on the part of the patient as well as the physician.
