The presence of metaplastic ossification within a atypical lipomatous tumour /well differentiated Liposarcoma (ALT/WDLPS) is a rare occurrence. We report a case ALT/WDLPS with unusual extensive metaplastic bone formation in a 30 years female who complained of swelling in the right shoulder for the past one and a half years.

Rhinoliths are mineralised foreign bodies in the nasal cavity that are a chance finding at anterior rhinoscopy. Undiscovered, they grow appreciably in size and can cause a foul-smelling nasal discharge and breathing problems. Giant nasal stones are now a very rare occurrence, since improved diagnostic techniques, such as endoscopic/microscopic rhinoscopy, now make it possible to identify foreign bodies at an early stage of development. We report the case of a 37-year-old patient who, at the age of 5-6 years, introduced a foreign body, probably a stone, into his right nasal cavity. On presentation, he complained of difficulty in breathing through the right nostril that had persisted for the last 10 years. For the past four years a strong fetid smell from the nose had been apparent to those in his vicinity. Under general anaesthesia, the stone was removed in toto from the right nasal cavity. The possible genesis of the rhinolith is discussed, our case compared with those described in the literature, and possible differential diagnoses are considered.

Primary small intestinal liposarcomas originating in the small bowel are uncommon with a generally poor prognosis due to the advanced stage at the time of diagnosis. We describe a case of primary small bowel dedifferentiated liposarcoma presenting as a solid mass in the right iliac fossa. The current case is unusual as the tumour seemingly originated from the bowel and the well-differentiated component was seen extensively infiltrating the bowel wall including the small bowel submucosa.

There has been a tremendous increase in interest in bioethics, which has come in direct response to the substantial advances in biomedical research and medical technology over the past 30 years. The more sophisticated medical science and technology becomes, the more sophisticated are questions that are raised: Who has the right to decide whether a medical treatment should be initiated, continued, or stopped? How much information are healthcare professionals required to give to patients? When should a patient's right to confidentiality be violated? When, if ever, is active or passive euthanasia or abortion justified, and who has the right to decide on these issues?

We report the case of a “fat-rich” (spindle cell-poor) variant of an atypical spindle cell/pleomorphic lipomatous tumor in a 63-year-old female patient presenting with a firm, painless soft tissue mass on the right hip. Atypical spindle cell/pleomorphic lipomatous tumor is a very recently described low-grade adipocytic neoplasm, which occurs predominantly in adults with a predilection for the limbs and limb girdles. In the present case, the diagnosis of an atypical spindle cell/pleomorphic lipomatous tumor was challenging because the tumor was almost exclusively composed of an atypical adipocytic component (resembling “classical” atypical lipomatous tumor/well-differentiated tumor) with only very focal presence of the diagnostic atypical morphologic features (atypical spindle-shaped cells, floret-like multinucleated cells, and “bizarre” pleomorphic [multinucleated] cells). The possibility of a “classical” atypical lipomatous tumor/well-differentiated liposarcoma was ruled out by immunohistochemistry (lack of MDM2 expression and loss of Rb expression) and molecular genetic testing (no amplification of MDM2 and presence of monoallelic deletion of RB1). Another interesting morphologic observation in this case was the striking perivascular location of the atypical spindle/pleomorphic cells in some areas (so-called “pericytic mimicry”). To our knowledge, pericytic mimicry has not been reported in the setting of an atypical spindle cell/pleomorphic lipomatous tumor.

The challenges of including factual information in public policy and political discussions are many. The difficulties of including scientific facts in these debates can often be frustrating for scientists, politicians and policymakers alike. At times it seems that discussions involve different languages or dialects such that it becomes a challenge to even understand one another’s position. Oftentimes difference of opinion leads to laws and regulations that are tilted to the left or the right. The collaborative balancing to insure public and natural resource interests are protected ends up being accomplished through extensive litigation in the courts. In this article, the author discusses the history of environmental balancing during the past three decades from the perspective of a field biologist who has used the strength of our policies, laws and regulations to fight for the protection of our Commonwealth’s aquatic resources. For the past 7 years, the author has taken over the reins of “the most powerful environmental agency in Pennsylvania” and charted a course using science to properly represent natural resource interests in public policy and political deliberations.

The right to the flow of income from water is vigorously pursued, protected, and fought over in any arid part of the world. Pakistan is of course no exception. Reform of irrigation institutions necessarily changes the rights to water, whether it be those of farmers, government, or government functionaries. Those perceived rights may be explicit and broadly accepted, or simply takings that are not even considered legitimate. Nevertheless they will be fought over. Pakistan has a long history of proposals for irrigation reform, little or none being implemented, except as isolated pilot projects. Thus, to propose major changes in irrigation institutions must be clearly shown to have major benefits to justify the hard battles that must be fought and the goodwill of those who might win those battles for reform. Proponents of irrigation institution reform have always argued the necessity of the reforms and the large gains to be achieved. Perhaps, however, those arguments have not been convincing. This paper will briefly outline the failed attempts at irrigation reform to provide an element of reality to the discussion. It will then proceed to make the case of the urgency of reform in a somewhat different manner to the past. Finally, current major reform proposals will be presented. This paper approaches justification of irrigation reform by focusing on the agricultural growth rate. It does so because that is the critical variable influencing poverty rates and is a significant determinant of over-all economic growth rates. The paper decomposes growth rates and suggests a residual effect of deterioration of the irrigation system that is large and calls for policy and institutional reform. The data are notional, suggesting the usefulness of the approach and paves the way for more detailed empirical analysis and enquiry for the future.

Abstract Germany is one of few jurisdictions with a bifurcated patent system, under which infringement and validity of a patent are established in separate proceedings. Because validity proceedings normally take longer to conclude, it can occur that remedies for infringement are imposed before a decision on the patent’s validity is available. This phenomenon is colloquially known as the ‘injunction gap’ and has been the subject of increasing criticism over the past years. In this article, I examine the injunction gap from the perspective of the right to a fair trial enshrined in Art. 6 of the European Convention on Human Rights. I find that the case law of the European Court of Human Rights interpreting this provision supports criticism of the injunction gap, because imposing infringement remedies with potentially far-reaching consequences before the validity of a patent has been established by a court of law arguably violates defendants’ right to be heard. Such reliance on the patent office’s grant decision is no longer warranted in the light of contemporary invalidation rates. I conclude that the proliferation of the injunction gap should be curbed by an approach to a stay of proceedings which is in line with the test for stays as formulated by Germany’s Federal Supreme Court. Under this test, courts should stay infringement proceedings until the Federal Patent Court or the EPO’s Board of Appeal have ruled on the validity of a patent whenever it is more likely than not that it will be invalidated.

Through the case of the New Right movement in South Korea in the early 2000s, this article explores how history has become a battleground on which the Right tried to regain its political legitimacy in the postauthoritarian context. Analyzing disputes over historiography in recent decades, this article argues that conservative intellectuals—academics, journalists, and writers—play a pivotal role in constructing conservative historical narratives and building an identity for right-wing movements. By contesting what they viewed as “distorted” leftist views and promoting national pride, New Right intellectuals positioned themselves as the guardians of “liberal democracy” in the Republic of Korea. Existing studies of the Far Right pay little attention to intellectual circles and their engagement in civil society. By examining how right-wing intellectuals appropriated the past and shaped triumphalist national imagery, this study aims to better understand the dynamics of ideational contestation and knowledge production in Far Right activism.

Penetrating transorbital injury with skull base involvement is a rare occurrence from a crayon. We report a case of a 2-year-old male who sustained a penetrating crayon injury through the right orbit and lamina papyracea into the posterior ethmoid sinus complicated by cerebrospinal fluid leak. There have been no other reported cases of this type of injury by a crayon.
