[Male Refractory Urethral Diverticular Abscess Requiring Transurethral Fenestration : A Case Report].

An 85 year-old man was referred to our hospital because of a relapse of abscess after open surgical drainage of the right scrotum. Computed tomography (CT) showed fluid accumulation in the right scrotum and around the membranous urethra. The abscess was controlled by an open surgical drainage of the right scrotum, CT guided percutaneous drainage of the periurethral abscess and administration of antibiotics.

Convergent Synthesis of trans-2,6-Disubstituted Piperidine Alkaloid, (-)-iso-6-Spectaline by Palladium-Catalyzed Cyclization.

The plant alkaloids, iso-6-spectaline and spectaline, isolated from the Cassia or Senna genera contain a characteristic 2,6-disubstituted piperidin-3-ol scaffold. Although both natural products are reported to exhibit a variety of interesting biological activities, few stereo-selective schemes for the construction of the 2,6-disubstituted scaffold have been reported. Following our previous studies regarding the synthesis of (+)-spectaline, herein we report the first convergent synthesis of (-)-iso-6-spectaline using a cross-metathesis under thermal conditions where the cis-2,6-disubstituted piperidin-3-ol scaffold is condensed with a long alkyl chain containing a terminal olefin.

Portosystemic Encephalopathy without Liver Cirrhosis Masquerading as Depression.

A 69-year-old woman was hospitalized due to progressive lethargy with hyperammonemia. Five months before the current admission, she was diagnosed with depression based on her low level of daily physical activity and thus began taking antidepressants. Abdominal computed tomography revealed a portosystemic shunt running between the left renal vein and inferior mesenteric vein.

Inhibitory effect of electroacupuncture on murine collagen arthritis and its possible mechanisms.

The influence of electroacupuncture (EA), a traditional Chinese medical treatment, on type II collagen-induced arthritis (CIA) was examined in DBA/IJ mice in vivo. Mice were immunized intradermally twice at a 3-week interval with bovine type II collagen (C II). EA stimulation, begun on day 21 simultaneously with the second immunization, was applied at the acupoint equivalent to GV4 three times a week for 3 weeks.

[Chemotherapy-resistant CD7-positive stem cell lymphoma presenting with intra-abdominal mass].

We report a case of CD7+ stem cell lymphoma. A 47-year-old man presented with general malaise and lumbago in April 1997. The patient exhibited swollen left cervical lymph-nodes and an intra-abdominal bulky mass.
