BACKGROUND: To investigate the possibie difference, if any, between office blood pressure(BP) and home BP may be important in the diagnosis and treatment of hypersensive patients. This report deails the difference between the two BP's and the usefulness of digital electronic sphygmomanometer(DES) for self-monitoring of home BP. METHODS: The BP's of 14 patients with essential hypertension were measured with mercury sphygmomanometers at outpatient department by physician and with DES at home(twice a day) by the patients. Patients were followed up every 2 weeks for 4 weeks and previous 2 weeks' average home BP's were compared with the office BP's of each 2 weeks' end. RESULTS: There was a significant difference between office and home BP(both systolic and diastolic) ; office average BP(151/95mmHg) was higher than home average BP(136/86mmHg). CONCLUSION: Caution may be needed in the interpretation of office BP unless it is measured several times after adequate rest.

We examined C3H pregnant mice at 15 days (70% gestation) after treatment of lipopolysaccaride (LPS) to observe the changes of IL-6 concentration in maternal serum and amniotic fluid and expression of IL-6, IL-13 & TIMP-3 in placenta, fetus and endometrium, and to investigate the correlation among IL-6, IL-13 and TIMP-3. The results were as follows: 1) IL-6 in serum and amniotic fluid after treatment of LPS was significantly elevated; peaked at 1, 2, 4, 5 hours and decreased to control level at 8 hours (P<0.05). IL-6 in placental disc, chorioamnionic membrane, fetus, decidua and endometrial epithelium was overexpressed significantly at 1, 2, 4 hours after treatment of LPS (P<0.05). IL-6 overexpression was more significantly increased in maternal tissue than fetal tissue (P<0.05). 2) Increased concentration of amniotic fluid IL-6 was equally originated from transplacental crossage of maternal serum IL-6, and direct local production of IL-6 from placenta, fetus and endometrium (P<0.05). 3) IL-13 in placental disc, chorioamnionic membrane, fetus, decidua and endometrial epithelium was overexpressed after treatment of LPS, but not significant statistically. 4) TIMP-3 was overexpressed in placental disc, chorioamnionic membrane, fetus and decidua. TIMP-3 overexpression was more significant in placental disc than other tissues (P<0.05). 5) Overexpressions in IL-13 and IL-6 revealed direct proportional correlation coefficient (Spearman correlation coefficient, 0.5212 ; P<0.05). IL-6 expression was a head of overexpression of TIMP-3, but not significant. In conclusion, all of IL-6, IL-13 and TIMP-3 relate with inflammatory response, especially IL-6 in maternal serum, amniotic fluid and tissue of placenta, fetus and endometrium was so sensitive that it can be an indicator for antenatal diagnosis of chorioamnonitis, and amniotic fluid IL-6 is equally originated from maternal serum and from tissue of placenta, fetus and endometrium. IL-13 and TIMP-3 may have parallel correlation to the IL-6 in fetal and maternal tissue after treatment of LPS.

BACKGROUND: The placenta from a pregnancy that is complicated by intrauterine growth retardation (IUGR) tends to be smaller than that from a normal pregnancy. To investigate this difference, we analyzed the telomerase activity, the proliferative activity and the mRNA levels of apoptosis mediators in placentas. METHODS: In 20 placentas from normal third-trimester pregnancies and 22 placentas form pregnancies that were complicated by IUGR, the telomerase activity was detected by a telomeric repeat amplification protocol assay. The proliferative activity was assessed by immunohistochemical staining using the MIB-1 monoclonal antibody. The expression of the apoptosis mediator was evaluated by semi-quantitative reverse transcription-polymerase chain reactions for fas and fas ligand. RESULTS: Telomerase activity was detected in 2 (10%) of 20 normal placentas, whereas it was not observed in all tested 13 placentas that were associated with IUGR. The proliferative activity was significantly low in the placentas that were associated with IUGR (7.44+/-2.96%), compared with the normal placentas (11.0+/-3.48%, p=0.002). There was no statistically significant difference in the mRNA levels of fas or fas ligand between two groups. CONCLUSIONS: Low telomerase and proliferative activities in the placenta may play a role in the pathogenesis of IUGR.

Telomerase is an enzyme that maintains telomeres and prevents telomere shortening, and may be linked with cellular proliferation or the aging process. The purpose was to examine telomerase activity in human chorionic villi from early and term normal pregnancies, and to analyze the correlation of telomerase activity (TA) with MIB-1 & bcl-2. A total of 37 placentae were obtained from 16 early and 21 term pregnancies. TA was assayed by telomeric repeat amplification protocol, and immunohistochemical staining was performed for MIB-1 & bcl-2 expression. TA & MIB-1 expression were strong in early placenta, but bcl-2 was highly expressed in term placentae. Thirteen (81.25%) of 16 early placentae showed TA, but only 2 (9.52%) of 21 term placentae expressed TA (p<0.01). MIB-1 was observed in nuclei of cytotrophoblast, and the expression rate was 16.09% in early placentae and 2.87% in term placentae (p<0.01). bcl-2 was observed only in the cytoplasm of syncytiotrophoblast. Term placenta demonstrated stronger expression of bcl-2 compared to early placentae (p<0.05). These findings suggest that TA, MIB-1 & bcl-2 expression are critically regulated over the course of gestation: cytotrophoblast, main cells of early chorionic villi, may be a common source of telomerase and proliferative activity. The TA showed good correlation with cellular proliferative activity. Syncytiotrophoblast, may be a main source of bcl-2 expression which is stronger in the term placentae.

Bladder reconstruction using bowel segments, especially the ileum, has become a realistic option for urinary diversion. There is only one prior case of squamous cell carcinoma of the ileal neobladder that has been reported in the clinical literature. Here we report a patient with a spectrum of squamous cell lesions, including squamous cell carcinoma, sarcomatoid carcinoma, squamous papilloma and squamous metaplasia that developed in the ileal neobladder. A 46-year-old woman underwent a hysterectomy, cystectomy and ileocystoplasty for tuberculosis 25 years previously complained of urinary frequency and gross hematuria for one week. A pelvic CT revealed a 6.3 cm mass in the neobladder. The histopathological examination showed an 11x8 cm polypoid fragile mass with a microscopically well-differentiated squamous cell carcinoma, squamous papilloma and non-tumor squamous metaplasia.

Pancreatic neuroendocrine tumors (PNET) are rare, with approximately 2.2 in 1,000,000 people affected annually. In the classification of neuroendocrine tumors, glucagonomas are a functional PNET and comprise 1.6% of PNET. Glucagonoma syndrome is a paraneoplastic syndrome that is characterized by necrolytic migratory erythema, weight loss, anemia, and diabetes mellitus. Metastatic disease at presentation is common, but is often limited to the liver and regional lymph nodes. Sunitinib malate improves the progression-free and overall survival of PNET. This report presents a 45-year-old Asian woman with prolonged neutropenia after sunitinib treatment of a glucagonoma with multiple hepatic metastases. The severity of the neutropenia after the sunitinib treatment fluctuated from grade 1 to 4 repeatedly, with a non-febrile pattern. Ultimately, the patient did not recover from the neutropenia, even after stopping the sunitinib.

Sugammadex is a specific antagonist of aminosteroidal neuromuscular blocking agents with 1:1 binding to guest molecules. Sugammadex can also bind to other drugs having a steroid component in its chemical structure. In this in vivo experiment, we investigated the differences in the recovery of rocuronium-induced neuromuscular blockade using sugammadex pre-exposed with two different concentrations of hydrocortisone. Methods: The sciatic nerves and tibialis anterior muscles of 30 adult Sprague–Dawley rats were prepared for the experiment. The sciatic nerves were stimulated using a train-of-four (TOF) pattern with indirect supramaximal stimulation at 20 s intervals. After 15 min of stabilization, a 250 μg loading dose and 125 μg booster doses of rocuronium were serially administered until > 95% depression of the first twitch tension of TOF stimulation (T1) was confirmed. The study drugs were prepared by mixing sugamadex with the same volume of three different stock solutions (0.9% normal saline, 10 mg/ml hydrocortisone, and 100 mg/ ml hydrocortisone). The recovery of rats from neuromuscular blockade was monitored by assessing T1 and the TOF ratio (TOFR) simultaneously until T1 was recovered to > 95% and TOFR to > 0.9. Results: In the group injected with sugammadex premixed with a high concentration of hydrocortisone, statistically significant intergroup differences were observed in the recovery progression of T1 and TOFR (P < 0.050). Conclusions: When sugammadex was pre-exposed to a high dose of hydrocortisone only, recovery from neuromuscular blockade was delayed. Delayed recovery from neuromuscular blockade is not always plausible when sugammadex is pre-exposed to steroidal drugs.
