to be an indication for surgical intervention. The goals of surgical intervention are to eliminate intrapleural air collection and prevent recurrence. Diverse procedures have been reported in the surgical treatment for spontaneous pneumothorax. We review the literature regarding the VATS approach for spontaneous

STREPTOMYCIN was first described over five years ago by Waksman and his coworkers.21 As experience has accumulated regarding its clinical use, manifes-tations of toxicity have become increasingly and significantly apparent. Depres-sion of the blood-forming organs has been, however, an uncommon occurrence, and only two previous cases of aplastic anemia due to streptomycin are known to have been reported at the time of this communication. Little evidence of toxic effects of streptomycin administration upon the hematopoietic system has been observed in animal studies. Feldman and Hin-shaw10 noted no effect on hematopoietic tissues or hemoglobin values in tubercu-lous guinea pigs treated for 54 to 61 days with streptomycin. Molitor and associ-ates,17 in chronic toxicity experiments using mice, rats, guinea pigs, monkeys and dogs, found a slight anemia in monkeys only. This was most common in those animals treated 66 days. In monkeys and dogs, Mushett and Martland19 found a slight, transient normocytic anemia without changes in the other formed ele-ments of the blood. The marrows of these animals and of rats similarly treated

seminomas have been reported in the world literature. We present a case of bilateral synchronous testicular seminoma, the current literature on the management of stage I seminoma, and the implications for radiotherapy. A forty-year-old man presented with synchronous bilateral classical seminomas, both stage

Introduction. Inverted papilloma (IP) is an uncommon, benign yet aggressive neoplasm characterised by high recurrence rates and tendency towards malignant transformation.Themajority of IP cases originate in the ethmoid region, lateral wall of the nasal fossa, andmaxillary sinus.The authors report a case of an IP originating primarily from the nasolacrimal duct (NLD).Case.A69-year-old Caucasian gentleman presented with a lump in his right medial canthal region, epiphora, and discharge bilaterally. Radiological investigation revealed a well-defined, heterogeneous mass within the proximal NLD eroding the bony canal, protruding into the

that can be used to think about systematic changes in monetary policy institutions and rules. The literature has not yet converged on a particular set of assumptions for identifying the effects of an exogenous shock to monetary policy. Nevertheless, there is considerable agreement about the qualitative

Despite the very extensive literature on dropout from higher education, much remains unknown about the nature of the dropout process. In large measure, the failure of past research to delineate more clearly the multiple characteristics of dropout can be traced to two major shortcomings; namely

In this paper we develop some statistical theory for factor models of large dimensions. The focus is the determination of the number of factors, which is an unresolved issue in the rapidly growing literature on multifactor models. We propose a panel Cp criterion and show that the number of factors

Reigning measures of psychological well-being have little theoretical grounding, despite an extensive literature on the contours of positive functioning. Aspects of well-being derived from this literature (i.e., self-acceptance, positive relations with others, autonomy, environmental mastery
