Spermatic Cord Lymphoma: A Case Report and Literature Review
Spermatic cord lymphoma is a rare lethal disease. It has a poor prognosis even in stage I or II disease when treated locally, therefore, multidisciplinary treatment for early stage is recommended. On the other hand, the treatment of choice for stage III or IV spermatic cord lymphoma remains to be determined. It is said that spermatic cord lymphoma is clinicopathologically similar to primary testicular lymphoma, therefore the treatment of spermatic cord lymphoma has often been determined by reference to the recommended treatment for primary testicular lymphoma. Here we report a new case of spermatic cord lymphoma, which was found in stage IV disease. We also review thirty-three cases which have been reported as spermatic cord lymphoma to date, and discuss treatment options

Interface Electronic Properties Between a Gold Core and Thiolate Ligands: Effects on an Optical Absorption Spectrum in Au<sub>133</sub>(SPh-tBu)<sub>52</sub>
We analyze the electronic structures
and optical absorption spectrum
of Au<sub>133</sub>(SPh-tBu)<sub>52</sub>, particularly in terms of
interface electronic properties between the Au core and the thiolate
ligands. Computations are performed by using the time-dependent density
functional theory approach in real-time and real-space that has recently
been developed by our group. Local density of states analysis reveals
a relationship between an icosahedral Au core and a thiolate-protected
Au cluster; Au atoms associated with the edge or surface sites of
the icosahedral core anchor the ligands to the core, whereas Au atoms
associated with the apex sites bridge two thiolates forming −S–Au–S–
bonds. We compare the optical absorption spectrum of Au<sub>133</sub>(SPh-tBu)<sub>52</sub> with that of an icosahedral Au<sub>146</sub> bare cluster to clarify effects of the ligands on the optical absorption.
The absorption intensity for Au<sub>133</sub>(SPh-tBu)<sub>52</sub> is obviously higher than that for the bare cluster. The significant
increase in the optical absorption of Au<sub>133</sub>(SPh-tBu)<sub>52</sub> is attributed to mutual enhancement of electric polarizations
induced both in the Au core and in the thiolate ligands. The effect
of the enhancement is computationally visualized by analyzing the
electric fields generated in the Au core and the thiolate ligands
A Case of the Nutcracker Syndrome Developed after Delivery
We report a case of nutcracker syndrome that developed after delivery. A 32-year-old woman visited our clinic complaining of gross hematuria 4 months after delivery. Urethrocystoscopic examination failed to show hematuria coming from the ureteral orifice; however, enhanced computed tomography revealed the compression of the left renal vein between the aorta and superior mesenteric artery. Therefore, we diagnosed her with nutcracker syndrome and conservatively observed her. The macrohematuria disappeared by itself after 1 month. This is the first report to describe a case of nutcracker syndrome that developed after delivery
