Association of Splenoma, Peliosis and Lipid Histiocytosis in Spleen or Accessory Spleen Removed in 2 Patients with Chronic Idiopathic Thrombocytopenic Purpura after Long Term Treatment with Steroids

In 2 patients with a long lasting cortico-dependent chronic idiopathic thrombocytopenic purpura, splenectomy in one and ablation of an accessory spleen in the other, disclosed a complex association of splenoma, peliosis and lipidosis of the spleen, with a secondary sea blue histiocytosis in one case. The relation of this curious association with thrombocytopenia and with the long treatment with corticosteroids is discussed, with a review of the literature.

Alimentary tract duplications in children: case and literature review.

This report reviews 11 alimentary tract duplications over a 25-year experience at Children's Hospital Medical Center of Akron, Ohio. The cases are compared and contrasted to the literature with respect to lesion, location, and patient presentation. There were no multiple duplications in this series. Clinical presentations were related to obstruction, abdominal pain, and/or hemorrhage. There were four foregut duplications, five midgut duplications, and two hindgut lesions. All patients were treated by surgical removal and all survived. One case was an incidental finding at appendectomy. Pooled data from five large series of duplications revealed the ileal region to be involved in 41 percent of all duplications, followed by esophageal (21%), gastroduodenal (12%), and jejunal (8%). Diverticular, recanalization, and split notochord theories of pathogenesis are discussed. The curious association between duplications and gastric mucosa is explored.

Abstract Radio emission lines of H2O, SiO, HCN, and CO have been searched in the circumstellar envelopes of carbon stars which exhibit the 10 μm silicate feature in the IRAS low-resolution spectra. Water maser emission at 22 GHz has been detected in V778 Cyg. No other emission has been detected in the carbon stars BM Gem, V778 Cyg, and EU And. Two competing interpretations for this curious association of the silicate feature and the water maser with the carbon star, the transient stage hypothesis and the binary one, are examined based upon the present observations. Five other carbon stars and two S stars were also observed for comparison.

Eocene-Oligocene: A Time of Transition: ABSTRACT

The Eocene-Oligocene is a time of transition from a warm early Tertiary world with low vertical and latitudinal thermal gradients to the Neogene world with steep vertical oceanic gradients and high latitudinal gradients between equator and poles. The transition between these two regimes occurred primarily between the middle Eocene and middle Oligocene and can be observed in faunal and floral assemblage changes, associated paleotemperature changes, periodic current intensification as implied by increased carbonate dissolution and hiatuses, eustatic sea level changes, and the curious association of microtektites and iridium anomalies with several of these intervals. Population studies of planktonic foraminifers in 14 DSDP sites in the Atlantic, Pacific, and Indian Oceans indicate a general cooling trend between the middle Eocene and Oligocene. Major faunal changes indicating cooling episodes occur, however, at discrete intervals: middle Eocene 44 to 43 Ma (P13); middle/late Eocene boundary 41 to 40 Ma (P14/P15); late Eocene 39 to 38 Ma (P15/P16); Eocene/Oligocene boundary 37 to 36 Ma (P18); and late Oligocene 31 to 29 Ma (P20/P21). Each cooling episode resulted in the extinction of warmer water species and evolution and dominance of cooler water species. This trend is associated with the development of a steep vertical thermal gradient and resulting stratification in the upper water masses (0 to 300 m, 1,000 ft) in the latest Eocene. 18The presence of microtektites and iridium anomaly in latest Eocene sediments has resulted in the scenario of catastrophic extinctions due to a bolide impact. The present study reveals multiple microtektite occurrences at 43 Ma, 40 Ma, 38 Ma, 34 Ma, and 30 Ma. Moreover, these microtektite occurrences coincide with intervals of increased carbonate dissolution and/or hiatuses. This suggests that microtektites are concentrated as a result of carbonate dissolution and selective winnowing of sediments at these intervals. Consequently, a concentration of microtektites in deep-sea sediments may not always imply a bolide impact, nor is there any evidence of catastrophic extinctions during Eocene-Oligocene time.

Mafic and ultramafic rocks associated with granites in the Vardar zone

SEVERAL ophiolitic alignments have been classically recognised in the Dinarides and the Hellenides (Fig. 1). The Eastern alignment, located near the Serbo–Macedonian massif in the Vardar zone, shows curious associations of mafic and ultramafic rocks with granites. Here a brief description of the Guevgueli magmatic complex which belongs to the Eastern alignment helps illustrate this peculiarity: petro graphic and major element data seem to prove that these associations occur on the border of opening inter-arc basins.

McCune-Albright's syndrome following adrenalectomy for Cushing's syndrome in infancy

This report adds a new example to the curious association of polyostotic fibrous dysplasia with various endocrine disorders. A girl developed symptoms of Cushing's syndrome at the age of 1 month. Total bilateral adrenalectomy was carried out when the infant was 4 months of age. Both glands showed nodular adrenal cortical hyperplasia. Within a period of 8 to 44 months following surgery, the clinical picture of McCune-Albright's syndrome became apparent, including skin pigmentation, polyostotic fibrous dysplasia, and sexual precocity.

Metastasis of cancer to cancer. A case report.

MULTIPLE primary malignant neoplasms are now regarded as a common occurrence and not a medical curiosity. Despite the relative frequency of multiple malignant tumors, instances of one cancer metastasizing to another are most uncommon. The case described in this report is an example of this rare and curious association. Report of a Case A 68-year-old white male entered St. Francis Hospital, La Crosse, Wis., for the first time on June 10, 1958, because of pain in the middorsal spine of 2 weeks' duration. The pain was described as sharp, severe, and continuous, with radiation to the right lower chest anteriorly. System review was otherwise negative. Past medical history was not remarkable. His mother died of metastatic carcinoma of the thyroid at age 65. Physical examination revealed a well-developed, moderately obese man with normal vital signs. Examination of the head and neck disclosed a single, 2-cm. firm node in the left

DESMOID TUMOUR IN FAMILIAL POLYPOSIS OF THE COLON

SummaryFamilial polyposis is associated sometimes with an abnormal behaviour in certain other tissues. Osteomata, soft tissue tumours, sebaceous cysts and intra‐abdominal fibrous tissue masses may co‐exist with familial polyposis.A case is recorded in which a desmoid tumour appeared in the wound after surgical treatment of familial polyposis. This is the 17th case to be reported in the literature.Pathologically, the tumour appears to be histologically distinct. from palmar and plantar fibromatosis nor does it seem to be inflammatory in origin.Desmoid tumours in surgical incisions are rare but the number that have been reportedin familial polyposis seems to indicate that in this disease there is a special tendency. The desmoid tumour may or may not be associated with fibrous tissue masses and osteomas elsewhere. In the case reported here these were present. It is known that this latter abnormality is transmitted as a Mendelian dominant. The curious association with polyposis has suggested two closely linked genes, or a pleotropic gene; a more acceptable theory is that the mutant gene has but a single action many steps removed from any clinically obvious manifestations.Recurrence after removal is so common that it seems excision should be very wide, to avoid the involved fascia1 sheets. The prognosis of these desmoids has not been established and it is possible that removal is not essential.

Birch, Johnson, and Elizabeth Carter: An Episode of 1738-39

Dr. Johnson's twenty-five-year friendship with the historian, antiquary, and clubman, Thomas Birch (1705-66), is significant for several reasons. First, it covers Johnson's earliest and most obscure years in London; second, it shows him in a curious association with a man of nearly the same age whose contemporary eminence and excellent social and intellectual connections contrasted remarkably with his own during the years before the Dictionary; and third, it gave rise to a large number of little-known Johnsonian passages in Birch's various correspondences. The Birch papers in the British Museum reveal their compiler as, among many other things, a voluminous if unsystematic and usually noncommittal chronicler of Johnson's career between 1738 and 1765. As a Whig with predominant Whig connections, Birch sometimes dealt harshly with Johnson. As a weathervane of taste, he was as often content to report current gossip or the progress of Johnson's projects as he learned of them through the newspapers, or in conversation with other friends or with Johnson himself. Once, by request, he wrote a short but extremely laudatory letter concerning Johnson's Dictionary. But the few well-known documents on the Birch-Johnson friendship suggest that relations were somehow disordered. Johnson's ten known letters to Birch are peremptory, cold, and without friendly expressions; his review of Birch's History of the Royal Society, published in 1756, was distinctly unfavorable; and his rumored final verdict on Birch (“a dull writer” [Boswell, i, 159]) is perhaps more widely known than Birch's services to English historiography. Johnson was content to remember Birch for a single talent: “he had more anecdotes than any man”—they flowed “like the river Thames” (Boswell, v, 255). Sir John Hawkins quoted Johnson on Birch, and the characterization, adapted by Boswell, has been endlessly repeated at Birch's expense: “Tom is a lively rogue; he remembers a great deal, and can tell many pleasant stories; but a pen is to Tom a torpedo, the touch of it benumbs his hand and his brain: Tom can talk; but he is no writer.”

Cancer and smoking.

THE curious associations with lung cancer found in relation to smoking habits do not, in the minds of some of us, lend themselves easily to the simple conclusion that the products of combustion reaching the surface of the bronchus induce, though after a long interval, the development of a cancer. If, for example, it were possible to infer that smoking cigarettes is a cause of this disease, it would equally be possible to infer on exactly similar grounds that inhaling cigarette smoke was a practice of considerable prophylactic value in preventing the disease, for the practice of inhaling is rarer among patients with cancer of the lung than with others.

Carcinoma of jejunum in intestinal polyposis with oral and digital melanosis.

Peutz apparently was the first to call attention to the curious association of intestinal polyposis with melanin pigmentation of the lips, oral mucosa, and skin of the digits. Jeghers and co-workers found 12 proved and 9 possible cases in the literature, to which they added 10 of their own. Since then, additional cases have been recorded, especially recently, suggesting that the disease is either becoming commoner or is being more frequently recognized. Strangely enough, the occurrence of carcinoma in the polypoid lesions of the bowel has not been especially emphasized in the cases reported. The case herein reported is typical of the syndrome. It is reported not only to add to the recorded number of these cases but also to emphasize the potential malignancy of the polypoid mucosa. Also included are some reflections on the care of these unfortunate persons. REPORT OF A CASE E. H. K., a 23-year-old white

Another Case of Species Versus Subspecies

Herpetological and systematic literature has recently been augmented by the appearance of a very admirable revision and summary of Long-Nosed Snakes of the Genus Rhinocheilus (Trans. San Diego Soc. Nat. Hist., vol. 9, No. 29, 1941, pp. 289-332, pis. 12-13, map) from the prolific pen of Laurence M. Klauber. The work mentioned was completed with no less painstakingly accurate care than usual in Klauber's studies; in fact only because of this thoroughness was the study brought to a satisfactory conclusion. More than one other author in recent years has given up a study of this genus with its seemingly meaningless complexity of variation of many types. The genus includes certain forms occurring in Mexico, the herpetological fauna of which has been a subject of my interest for some time, and accordingly I have had more than casual reason for examining Klauber's arrangement of species and subspecies. Only through a different manner of interpretation of his data can I suggest a certain change in the arrangement he proposes. The map reproduced herewith from Klauber's paper shows the distribution of the four forms of the genus, all of which he concludes represent subspecies of a single species. Two of the subspecies (antonii and tessellatus) are geographically distinct, while two others (clarus and lecontei) overlap so extensively both geographically and ecologically (at least no ecological segregation is yet apparent) that the relation between them cannot be visualized as the usual territorial one. As Klauber states (p. 320) : It may be suggested that these two forms were once separated until they had become distinct, but have not recontacted and are spreading through each other's territories, without completely merging into an intermediate pattern. This is a very plausible?? in fact almost inevitable?conclusion if the geographic or territorially theory is assumed to account for the evolution of these two races. This theory is, of course, almost universally accepted as an explanation of most speciation in animals. On the contrary, however, clarus and lecontei may have become differentiated in at least one other fashion?by some type of DeVriesian mutation. In the latter case, admittedly of very little potential occurrence, the newly-formed species may, and presumably usually does, spread through part or all of the range of the parent species, but on the other hand it may, of course, occupy a distinct area, providing conditions (both intrinsic and extrinsic) permit. Accordingly, either Klauber's explanation or the DeVriesian mutation theory may account for the curious association of clarus and lecontei.

THE ECONOMIC ASPECT OF INSECT ASSOCIATIONS WITH SPECIAL REFERENCE TO SOUTH INDIAN COCCIDAE (SCALE INSECTS AND MEALY BUGS)

The existence of such phenomena as parasitism, symbiosis, commen- salism, cannibalism and other curious associations in the animal world is a fact well known to all biologists; but as far as the writer is aware such relations are nowhere found in such numbers and in such extraordinary and remarkable varieties as in the realm of insects.

Is there more than one kind of rickets?

I. CLINICAL OBSERVATIONS SUGGESTING THE EXISTENCE OF MORE THAN ONE KIND OF RICKETS.For at least two years our attention has been attracted to the possibility that there might be more than one kind of rickets. We were led to think of this possibility as the result of the consideration of certain peculiar manifestations of the disease and associations with other diseases. The facts are as follows: Rickets occurs with great frequency in premature children, even when breast fed. It seems to affect the head more than the extremities or ribs. In a group of cases of rickets the disease shows an especial tendency to involve the shafts of the long bones declaring itself clinically by the occurrence of multiple fractures from trivial causes. There is a curious association between rickets and certain forms of secondary anemia (the so-called alimentary anemias and the anemias of the von Jaksch type). The rachitic involvement of the head in the children suffering from the combined conditions appears to be out of all p...
