SS-cream made with extracts from natural products is a topical agent for treating premature ejaculation (PE). In order to elucidate the penile vibratory threshold changes and clinical effects of various doses of SS-cream, 53 patients with primary PE were investigated in a double-blind randomized placebo-controlled study. The mean age was 37.3 +/- 6.4 years and mean ejaculatory latency was 1.37 +/- 0.52 minutes. Neither the patients nor their sexual partners were satisfied with their sexual lives. Vibratory threshold at the glans penis, penile shaft, scrotum and index finger were measured using a biothesiometer twice during the screening period and three times one hour after the application of respective creams (SS-cream 0.05, 0.10. 0.15, 0.20 gm and placebo 0.10 gm) on the glans penis according to the order of the allocation table in a randomized fashion. The efficacy of SS-cream was defined as when the vibration threshold increased by more than 4 microns compared to the value tested during the screening period. The vibratory thresholds at the glans penis increased significantly in a dose-dependent manner after the application of various doses (0.05, 0.10, 0.15, 0.20 gm) of SS-cream (p < 0.001), and the efficacy of SS-cream on the penile vibration threshold increased according to the increased dosage (penile shaft: 48.4, 51.6, 54.8, 64.5%, glans penis: 58.1, 67.7, 77.4, 83.9%, respectively). With these results, we concluded that SS-cream increased the penile sensory threshold dose dependently, and therefore it is clinically effective for treating the heightened penile sensory response in patients with PE.

The main purpose of this paper was to review the role of the hyoid movement in the swallowing process and the effect of swallowing posture, age, gender, bolus properties on the hyoid movement. The displacement of the hyoid bone was divided into vertical and forward displacement. The vertical displacement of the hyoid bone contributes primarily to epiglottic and laryngeal closure, while the anterior displacement contributes primarily to opening of the UES. The dysphagia patients often experienced a reduction in hyoid bone displacement. Therefore, further research on the movement of the hyoid bone in the deglutition, especially the relationship between anterior displacement and UES opening is necessary.

OBJECTIVETo compare the sex differences on brain stem auditory evoked potentials (BAEP) and P300 in the elderly patients with mild cognitive impairment (MCI) and the patients with Alzheimer's disease (AD).

METHODSThirty-eight elderly patients with MCI, 26 cases of AD and 20 health controls (HC) were examined with BAEP, P300 . Sex difference of the variables was compared inter-and intra-groups.

RESULTSSignificant sex differences of BAEP were found in the latency period wave III, V of left side in the MCI group (P <0.01), in the latency period wave IV, V of left side in HC group (P<0.01), and no such differences were found in AD group. The females had longer latency period in P300 measurement than males in MCI group (P <0.01), but there were no significant differences within AD or HC groups. The males showed significant differences in wave I, II in left side between the MCI and AD groups. The males also showed significant difference in wave I, III approximate, equals V in left side, wave IV in right side between AD and HC groups, and so did the females in wave I approximate, equals V in both sides. The males had significant difference in the left wave III, IV and right wave I, IV, V between MCI and HC groups, and so did the females in right side wave I, II, V. In P300, longer latency waves were found in AD group than in MCI group. Both sexes showed significant differences in the latency of Fz, Cz, Pz between AD and HC groups, but no significant differences were found in the latency of Fz, Cz, Pz in the females between the MCI and HC groups.

CONCLUSIONSex differences were found in the examination of both BAEP and P300 in MCI group, but not in AD group. The people of same sex have different expression of BAEP and P300 among MCI, AD and HC groups, suggesting the sex difference should be considered in the differential diagnosis.

OBJECTIVETo explore the role of monitoring sex chromosome chimeric status by fluorescence in situ hybridization (FISH) in the identification of leukemic extramedullary relapse and post-transplant lymphoproliferative disease (PTLD) in acute lymphocytic leukemia (ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSSix ALL patients who received sex-mismatched allo-HSCT and manifested extravisceral lymphadenectasis or local lump were investigated. The sex chromosome chimeric status in tumor tissues and bone marrows (BM) were monitored by FISH, and EBV-RNA in the tumor tissues were detected by in situ hybridization (ISH).

RESULTSThe sex chromosomes in BM of all 6 patients were 100% donor-derived. Among the sex chromosome chimeric status of tumor tissues, three patients were mainly recipient-derived, and the percentage of sex chromosomes derived from recipients were 100%, 100% and 98.0%, respectively, and then they were diagnosed leukemic extramedullary relapse. The other 3 patients were donor-derived, the percentage was 98.5%, 96.0% and 91.5%, respectively, and were diagnosed PTLD. EBV-RNA and latent membrane protein (LMP-1) were positive in 2 patients with PTLD and negative in the other 4 patients. One patient with extramedullary relapse obtained partial remission, one with PTLD gained complete remission, and the others died eventually after therapy.

CONCLUSIONMonitoring the sex chromosome chimeric status by FISH is an effective method to distinguish leukemic extramedullary relapse from PTLD in ALL received sex-mismatched donor HSCT.
