Vein graft drainage of the endolymphatic sac in patients with Meniere's disease

The blood supply of the endolymphatic sac, which has a role in the absorption of endolymph, is connected mainly to the meningeal artery separate from the branch of the cerebellar artery of the inner ear. Therefore, avoiding damage to the small vessels of the lateral wall of the sac should be important for restoring the absorptive function.In order to prevent adhesive closure of the drainage incision and restore the absorption function of the sac, we developed a new technique which restricts the drainage incision to a simple straight one on the rostral edge of the sac, and in which a drainge vein from the back of the patient's foot grafted in connection with a gelatin-film core to the incised sac. Our procedure was performed on 20 patients with Meniere's disease, who were followed up over 24 month. The results were favorable: recovery from vertago, was "complete" in 7 case (35%), "substantial" in 12 (60%), and "limited" in one case (5%) according to the new AAO-HNS formula (Miami, 1985).

A prospective survey of 474 patients with anorectal abscess.

A prospective survey of patients with anorectal abscesses treated at Cook County Hospital over a 35-month period produced data on 474 patients. The peak incidence was in the third decade of life. Males were affected 1.76 times more frequently than females. Perianal abscess was the most common anatomic type (42 per cent), with ischiorectal abscess (20 per cent) being second. The supralevator space was involved in 7 per cent of the abscesses. Primary fistulotomy was performed when an anal fistula could be demonstrated (34 per cent). Our standardized method of treatment, utilizing radial incisions for drainage, produced satisfactory results with a complication rate of 3 per cent, an in-hospital reoperation rate of 0.6 per cent, and an average hospital stay of 5.7 days.

Peach Springs Tuff: Its Bearing on Structural Evolution of the Colorado Plateau and Development of Cenozoic Drainage in Mohave County, Arizona

The Peach Springs Tuff, a welded ash flow of Miocene age, formerly blanketed a minimum area of 2,000 sq mi on both sides of the western edge of the Colorado Plateau in Mohave County, Arizona, and filled northeast-trending, pre–Colorado River canyons cut through the Paleozoic rocks. Paleomagnetic direction, petrography, and field relations indicate that the tuff is a single cooling unit of trachytic composition and normal polarity. It was erupted across the region prior to the last major movement of the plateau marginal faults, the completion of a significant amount of Basin and Range block faulting, and development of the existing topographic relief. A pre-tuff period of uplift and erosion exposed the Precambrian basement rocks directly west of the plateau. Gravel buried in canyons beneath the tuff on the edge of the Hualapai Plateau is evidence of northeast-flowing, incised drainage, in pre-tuff time, which probably continued northward along the Hurricane fault zone across the region where the younger canyon of the Colorado River is now. This ancient drainage system was disrupted by faulting, volcanism, and localized fluvial aggradation, followed by gradual incision of the modern Colorado River drainage. South of the Truxton Valley, there is evidence of a pre–middle Miocene drainage divide along the edge of the present plateau. All geologic evidence points to an early to middle Pliocene age for the modern Colorado River and associated tributary drainage on the Hualapai Plateau west of the Hurricane fault.

A Case of Muco-Cutaneous Lymphnode Syndrome Complicated by Acute Infantile Coxitis

Muco-Cutaneous Lymphnode Syndrome (1967 Kawasaki), usually affects the infants of four years-old and downward, has specific symptoms and signs such as fever unresponsive to antibiotics, injection of bulber conjunctva, hard edema of hand and foot, membranous desquamation of finger tip, injection and dryness of mucous membrane of oral cavity and lip, scarlet tongue, indefinte shaped skin eruption, and so on.This lesion often complicated with serous arthritis, but we can find no case report with pyogenic arthritis.This case admitted complaining of 39°C fever continuing for 9 days. Diagnosis of Muco-Cutaneous Lymphnode Syndrome was done by his characteristic symptoms, signs and laboratory findings. On 15th disease day, transient swelling of right hip joint region occured. Antibiotics and steroid agent improved his condition satisfactorily, but he did not walk. On 26th disease day, X-ray film showed right coxitis. Punction of hip joint proved pyogenic infection, and immediately incision for drainage was performed. Post operative course was satisfactory, and he discharged 3 weeks after operation.This case was reported in detail, and relationship of 2 disease complicated were also discussed.

The Cenozoic history of the southern Atacama Desert, Chile

Four episodes of landscape evolution are recognized, each of which has led to the development of a regional erosion surface. The first phase began upon elevation of northern Chile above sea level in the late Mesozoic, and each subsequent phase commenced with a major incision of drainage into the preceding landscape. Radiometric dating of pyroclastic flows shows that the earliest elements of the present topography already existed in the Lower Eocene, and that most landforms had developed by the Middle-Upper Miocene. Deep canyon formation characterized the latest erosional phase which commenced in the Upper Miocene and is still continuing. Tectonic elevation of the Cordillera de la Costa in relation to the longitudinal depressions seems to have occurred early in the landscape history, though later remobilization along major structures has since taken place. Erosional landforms in the high Andes are often blanketed by constructional volcanic features and the migration of eruptive centres since Miocene times has displaced the continental watershed to the east. Tectonically induced relative sea level changes have caused late Tertiary transgressive deposits in the littoral region to have been terraced during an irregular marine regression. The landscape history which spans the whole of the Tertiary indicates that Andean relief generation has been a prolonged pulsative process. Supergene enrichment of the copper deposits took place under the older erosion surfaces between the Lower Eocene and the Upper Miocene, and the economic viability of a prospective mine can be largely predicted from the overlying topography.

Classification of perihepatic abscesses.

The purpose of this paper is twofold: (a) to definitely establish the anatomy of the perihepatic spaces and correct the existing errors in both the surgical and the radiographic literature; and (b) to establish and demonstrate a classification which is practical anatomically and radio-logically. Much of the confusion concerning perihepatic abscesses exists because of dissections which distort the anatomic relationship after the abdomen is opened or because of impressions gained by key-hole incision for drainage. As is usual, the simplest approach becomes the most useful and accurate. A knowledge of the border-forming ligamentous attachments of the liver should give definition to all the multiple potential spaces around it and become the key to their localization. For a conceptual radiologic approach the most accurate localization appeared to be achieved by means of sagittal-section anatomy. For this purpose we used dry ice to freeze cadavers and with a band saw sliced multiple sagittal sections of the liver, each 5 cm in width. Identification was then made of the ligaments at their different levels and of the perihepatic spaces with their anatomic relationships to other organs. (In the accompanying figures a dotted line between arrows represents these attachments on subsequent sections.) Anatomy For a long time the anatomy of the spaces surrounding the liver has been incorrectly or inaccurately described. The error lay in an erroneous opinion of the position of the ligamentous attachments of the liver. Most authors, following earlier investigators (13, 15), showed the coronary ligament as suspending the liver from the diaphragm superiorly, thus dividing the right subphrenic space into an anterior superior in front of the coronary ligament and a posterior superior in back of it. This was the justification for Ochsner's twelfth rib extrapleural surgical approach to right posterior superior subphrenic abscesses. In this country Boyd pointed out in 1958 (4) that the right coronary ligament does not insert superiorly but surrounds the bare area posteriorly like all other intraperitoneal viscera. Thus, the so-called right posterior superior subphrenic space is a myth. It just does not exist, and the actual right subphrenic space extends much further back than was previously thought. The space below the inferior reflection of the right coronary ligament is actually in back of and below the visceral surface of the liver. This is what Ochsner was draining through his twelfth rib incision, and not, as he thought, a subphrenic space. Ochsner's incision is perfectly reasonable indeed to drain posterior right subhepatic abscesses, but Boyd stated in 1966 (3) that Trendelenburg's ninth-to-tenth rib transpleural incision was more adequate and direct for draining abscesses in the posterior aspect of the right subphrenic space just above the superior reflection of the coronary ligament.

A Study of Granite Relief from South-West Africa

AbstractThe writer describes the relief forms and destructional processes occurring in a group of granite hills in Damaraland, South-West Africa. The hills are attributed to the dissection of a former erosion surface by rejuvenated streams. Drainage incision has followed longitudinal and diagonal joint lines, which control the orientation and sub-division of individual groups of granite domes. The destruction of granite masses by plating, or the unloading of Unweathered shells, produces the dome outline, whereas the development of vertical jointing leads to granite tors. Domes may be cleaved along transverse joints to form secondary domelets, or split longitudinally to form narrow whalebacks. The former are lowered by plating to flat dome forms the latter are reduced by marginal fracturing, here termed mural weathering. Further wastage is by slow granular disintegration on low granite outcrops.

Climatic fluctuation, a suggested means for the development of lake terraces, Kunming, China

Pleistocene lake terraces in the Kunming basin, Yunnan, China, may have been formed during alternating wet and dry climatic regimes corresponding respectively to glacial and interglacial stages. Continuous uplift of the region and increased drainage incision during moist periods resulted in progressive lowering of the level of Lake Kun-Yang, whereas in more arid periods the level was stabilized by alluvial damming, with resulting accumulation of fluviolacustrine material on the basin floor.

Reflex Hyperemic Deossifications Regional to Joints of the Extremities

Localized deossifications in the extremities are rather common findings. Yet it appears that varied interpretations are offered as to their significance. Not infrequently they are ignored. Perhaps there may be a statement to the effect that there is an “osteoporosis,” insinuating a passive type of bone absorption, such as might be related to disuse. In cases of conspicuous absorptions, however, there is the opposite tendency—i.e., to exaggerate the roentgen evidence, even to the extent of assuming the presence of an infection or possibly a neoplasm. At least 7 referred cases are known to the writers wherein this latter extreme of interpretation prevailed. In 2 of these, amputations had been performed, but histopathologic studies revealed no evidence of malignant growth or even of infection—no substantial basis, indeed, for the amputations. In several of the other cases, amputations had not been performed but the cases had been referred for that purpose. Incisions for drainage of supposed abscesses or actu...

Phlegmons of the face and neck

1. 1. The mouth is a favorable breeding place for pathogenic organisms. Any hygienic improvement of the mouth previous to surgical interference will reduce the numbers of organisms and increase local tissue resistance. 2. 2. Surgical trauma reduces local resistance; surgery provides opportunity for invasion of organisms into deep tissues. 3. 3. Once invasion has occurred, the dissemination of infection depends on (a) the virulence of the organism, (b) the resistance of the host locally and generally. 4. 4. If infection occurs, it will tend to localize in the fascial compartments. 5. 5. Proper drainage of these compartments will depend greatly on the surgeon's familiarity with their anatomical construction. 6. 6. Correctly timed and adequately designed incisions for drainage are necessary. 7. 7. Local and general supportive treatments are essential; hospitalization is usually wise. 8. 8. Medicodental cooperation is most desirable.

Infection of fascial spaces of the palm

1. 1. A knowledge of anatomy is necessary for the proper diagnosis and treatment of infections of the fascial spaces of the palm. 2. 2. Such infections should be considered surgical emergencies and treated promptly. 3. 3. Incisions for drainage of these infections of the hand should be made by careful dissection, with the patient under general anesthesia and with a tourniquet on the arm. 4. 4. The function of the hand after such an infection will depend largely on adequate surgery plus persistent physical therapy.
