RESUMO

PURPOSE: Advances in endoscopic technology have led to the reevaluation of self-expandable metallic stent (SEMS) placement as a bridge-to-surgery (BTS) in patients with obstructive colorectal cancer. In Japan, after inclusion of SEMS placement as a BTS in the medical insurance coverage in 2012, this procedure has been increasingly performed. However, a transanal decompression tube (TADT) placement has been used as a BTS. We aimed to retrospectively evaluate the optimal strategy for obstructive left-sided colorectal cancer (OLCRC) by comparing SEMS and TADT placement with emergency surgery. METHODS: We included 301 patients with stage II and III OLCRC from 27 institutions. The study patients were divided into Surgery group (emergency surgery, n = 103), SEMS group (BTS by SEMS, n = 113), and TADT group (BTS by TADT, n = 85). We compared the survival and perioperative outcomes of patients in the Surgery group as a standard treatment with those in the SEMS and TADT groups. RESULTS: The 3-year relapse-free survival rate in patients in the Surgery group was 74.8%, while that in patients in the SEMS group and TADT group were 69.0% (p = 0.39) and 55.3% (p = 0.006), respectively. The technical success rate was not statistically different, but the clinical success rate was significantly higher in the SEMS group than in the TADT group (p = 0.0040). With regard to postoperative complications after curative surgery, the SEMS group had significantly lower of complications (≥ grade 2) than the Surgery group (p = 0.022). CONCLUSION: Patients who underwent SEMS placement for OLCRC had similar oncological outcomes to patients who underwent emergency surgery.

RESUMO

OBJECTIVE: The aim of the present study was to examine the association between subjects with self-awareness of fast eating and diagnostic components of metabolic syndrome in Japanese middle-aged male and female. PATIENTS AND METHODS: Subjects consisted of 3208 males (average age 50.6 years) and 2055 females (average age 50.0 years). Associations between subjects with self-awareness of fast eating and multiple components of metabolic syndrome (waist circumference, body mass index [BMI], blood pressure, and related blood sample tests) were evaluated. RESULTS: Significantly more males (57.7%) acknowledged themselves as "fast eater" than females (46.5%). Self-reported fast eaters showed significantly elevated body weight, BMI, and waist circumference in both genders. However, only male self-reported fast eaters showed high levels of blood pressure, fasting blood glucose, uric acid, and low-density lipoprotein (LDL)-cholesterol. CONCLUSION: Fast eating is associated with diagnostic components of metabolic syndrome. The effect of acknowledging themselves as fast eater presents a higher impact on males than on females in the middle-aged Japanese population. The present study indicates that finding subjects with self-awareness of fast eating may lead to the prevention of developing metabolic syndrome.

RESUMO

BACKGROUND: According to the 7th edition of the TNM staging system, stage IV metastatic colorectal cancer (CRC) at the time of initial diagnosis is sub-classified into stage IVA or IVB disease. Peritoneal carcinomatosis (PC), considered to have a dismal prognosis, is exclusively sub-classified into stage IVB, even though other metastases to a sole organ are sub-classified into stage IVA, which is considered to be associated with better survival. This retrospective study was undertaken to investigate the overall survival in metastatic CRC patients, focusing on PC patients. METHODS: We reviewed data on patients with metastatic CRC at initial diagnosis surgically treated between January 2006 and June 2011. A survival analysis was performed paying special attention to PC and sub-classifying patients with PC into three categories according to metastatic sites. RESULTS: There were 69 stage IVA patients (IVA group) and 83 stage IVB. Among stage IVB patients, 20 had isolated PC (PC-I group), 28 had PC with one or more other sites of metastasis (PC-II group), and 35 had at least 2 metastatic without peritoneal involvement (NPC group). Of 152 stage IV patients, 132 (87 %) underwent resection of the primary tumor and 19 (12 %) underwent radical resection of metastatic disease with microscopic free margins (R0 resection) including 5/20 (25 %) patients in the PC1 group. A total of 139 patients received oxaliplatin-based chemotherapy in a palliative (n = 125), neoadjuvant (n = 3), or adjuvant setting after R0 resection (n = 11). Compared with 36.6 months in the PC-I group, median survival was 32.5 months (P = 0.48) in the IVA group, 14.7 months (P = 0.07) in the PC-II group, and 12.9 months (P < 0.01) in the NPC group. CONCLUSIONS: The sub-classification of isolated PC into stage IVA instead of IVB might be more appropriate in the era of modern chemotherapy. Further investigation is warranted.

RESUMO

BACKGROUND: The goals of this retrospective study were to comprehensively evaluate the impact of hepatic lymph node (HLN) involvement on survival in patients with synchronous resectable or unresectable liver metastases from colorectal cancer and to highlight how to deal with such cases in the light of recent advances in chemotherapy. METHODS: The impact of HLN involvement on survival, along with various clinical, pathological, and therapeutic factors, was retrospectively evaluated in 61 patients with synchronous liver metastases from colorectal cancer (resectable, 26; unresectable, 35), undergoing resection of the primary tumor and histopathological evaluation between July 2000 and April 2008. RESULTS: The proportion with HLN metastasis was 11.5 % in resectable cases and 28.6 % in unresectable cases. On multivariate analysis using the Cox proportional hazards model, HLN metastasis (P < 0.001), along with non-resection of hepatic lesions (P < 0.001), larger metastatic tumor volume (P < 0.001), non-use of oxaliplatin-based chemotherapy (P < 0.001), involvement of 4 or more regional lymph nodes (P < 0.001), and excessive lymphatic invasion (P = 0.02), was identified as an independent risk factor for shorter survival. CONCLUSIONS: To establish a new therapeutic strategy for synchronous liver metastasis of colorectal cancer, the HLNs should be examined histologically in patients undergoing resection of their primary colon and rectal cancer.

RESUMO

Several procedures have been proposed for the prolapse of a loop colostomy. However, most are associated with a high recurrence rate or are rather expensive. We have newly developed a simple, safe, and inexpensive method, which is a modification of Thiersch's method, for repair of distal limb prolapse of a loop colostomy.

RESUMO

BACKGROUND: The aim of this study was to evaluate how sacrifice of the portal vein and/or hepatic vein affects remnant liver dysfunction after lateral segmentectomy or left lobe hepatectomy. MATERIALS AND METHODS: Among 130 patients who underwent donor hepatectomy between March 2002 and July 2011, we enrolled lateral segment (n=15) and left lobe donors (n=40). We evaluated the postoperative courses and the territory of venous obstruction or congestion based on the sacrificed portal vein or hepatic vein after the donor operation: lateral segment grafts (P4a, P4b, LV4) and left lobe grafts (MV5, MV8) according to the results analyzed by MeVis Distant Service. RESULTS: Among lateral segment donors, the predicted sacrificed territory of portal vein and hepatic vein was 14.3% (7.3%-19.4%) in P4a+4b: (P4a: 8.6%, P4b: 5.8%) and 2.9% (0%-8.4%) in LV4, respectively. On the other hand, in left lobe donors, the predicted congestive territory of the hepatic vein was 17.6% (2.8%-33.0%) in MV5+8 (7.8% in MV5 and 9.8% in MV8, respectively). The incidence of patients whose postoperative peak aspartate aminotransferase (AST) or alanine aminotransferase levels were higher than 500 IU/L was 20% in the lateral segment donors and 5% in the left lobe donors. The peak postoperative AST levels and territory of MV5+8 showed a significant positive correlation (R=0.569, P<.05) among left lobe donors. CONCLUSION: Territories of P4 in lateral segment donors and MV5+8 in left lobe donors impacted postoperative liver dysfunction. It is important to recognize the precise territory of the portal vein and the hepatic vein before the donor operation.

RESUMO

We report a new method of performing single-port laparoscopic surgery for appendiceal mucocele. The key points of our technique are placing a 3/4 circumferential skin incision with multiple radial splits on the confine of the umbilicus, use of a "home-made" multichannel port system, and trimming the skin incision straight through the confine of the umbilicus at the time of wound closure. A 65-year-old woman with appendiceal mucocele, 80 mm in diameter, successfully underwent ileocecal resection by this procedure. She remains in good health without any wound complications 8 months postoperatively.

RESUMO

The function of cumulus cells after sperm penetration is not well understood. The present study examined the phagocytic action of cumulus cells on sperm after dispersion of cumulus-oocyte complexes. In a co-incubation system of cauda sperm and cumulus cells, the sperm heads were beginning to vanish after 2.5h and 77%±1.34 of sperm heads had disappeared at 30 h. Most of the sperm heads were engulfed by cumulus cells. Immunofluorescent studies showed that cumulus cells were expressing the CD36 molecule, and sperm were exposing phosphatidylserine (PS). Anti-CD36 antibody and annexin V inhibited the engulfment of sperm by cumulus cells by 26.0% and 40.5%, respectively. These results suggested that the cumulus cells recognized the PS molecules on sperm via CD36 and this molecular interaction possibly triggered the phagocytosis of sperm by cumulus cells. These results suggest that cumulus cells might play a role in inhibiting undesired immune reactions induced by sperm antigens.

RESUMO

BACKGROUND: We have been performing curative resection of colon cancer via a minilaparotomy without utilizing any laparoscopic instruments as an alternative to laparoscopic-assisted approach. Based on our experiences and improved surgical techniques, we have devised a new method for performing resection of stage 0/I colon cancer via a circumferential periumbilical skin incision that is associated with better cosmesis than standard minilaparotomy. METHODS: The short- and long-term results of curative colectomy via a circumferential periumbilical skin incision without utilizing any laparoscopic instruments performed in selected patients with stage 0/I colon cancer between October 2003 and July 2004 were analyzed. RESULTS: There were 8 men and 2 women with a median age of 66.5 years (range 61-77 years). Their median body mass index was 22.4 kg/m(2) (range 21.1-27.7 kg/m(2)). Pathological stage according the TNM classification was stage 0 in 4 patients and stage I in 6 patients. Median operative time was 160.5 min (range 135-203 min), and median blood loss was 60 ml (range 5-330 ml). Postoperative complications consisted of seroma in two patients and small bowel obstruction in one patient. After a median follow-up period of 5.7 years, there were no recurrences or wound complications. CONCLUSION: Curative colectomy via a circumferential periumbilical skin incision seems oncologically safe, yields satisfactory cosmetic results, and may provide an alternative to single-incision laparoscopic surgery in selected patients with colon cancer.

RESUMO

BACKGROUND: This study evaluated the need for specific instruments when performing a curative resection of colon cancer via a minilaparotomy approach, which has been reported to be a minimally invasive alternative to a laparoscopic approach. METHODS: The feasibility, safety, and early oncological outcome were compared among 73 patients (first group), in whom a curative resection of colon cancer was performed via a minilaparotomy (skin incision < or =7 cm) utilizing specific instruments (North-bridge retractor system) between September 2002 and March 2005, and 94 patients (second group), in whom a similar procedure was performed without utilizing specific instruments between April 2005 and October 2007. RESULTS: The two groups did not differ significantly in terms of age, sex, body mass index, site of tumor, level of lymph node dissection, blood loss, UICC stage, number of harvested lymph nodes, incidence of postoperative complications, length of postoperative hospital days, or overall survival, although the frequency of prior abdominal surgery was higher (38.3 vs. 21.9%; P = 0.03) and the median operating time required for a standard lymph node dissection was shorter (120 vs. 135 min; P = 0.03) in the second group. CONCLUSION: With improved techniques and experience, specific instruments are not necessary for the performance of a curative colectomy via a minilaparotomy approach.

RESUMO

Assisted reproductive technologies have progressed significantly and have provided successful treatment for many infertile couples. However, more advanced technologies are required for severe infertility such as premature ovarian failure and ovarian impairment due to adjuvant therapy for cancer. Ovarian tissue cryopreservation followed by in vitro growth of isolated follicles is a feasible proposition for such patients. Close coordination of communication among follicle cells including oocytes, granulosa and theca cells is required for follicle growth. Crucial factors may regulate the gonadotropin-independent and -dependent follicle growth stages. To facilitate development of a culture system for early growing follicles, DNA microarray analysis of mouse ovaries recovered at 7, 10, 13, 16 and 19 days of age was performed to identify factors required for the growth of early-stage follicles. These studies showed strong intensity of zona pellucida glycoproteins, bone morphogenic protein-15 (BMP-15) and growth differentiation factor (GDF-9) in 7 days old mice, which gradually declined in 19 days old mice. KIT, KIT ligand, anti-müllerian hormone (AMH) and platelet-derived growth factor (PDGF), known as granulosa cell secreted factors, also showed relatively high expression. These studies will facilitate our understanding of the regulatory factors involved in folliculogenesis and thereby enable establishment of in vitro culture system for ovarian follicles.

RESUMO

CD52 is a GPI anchor protein present in lymphocytes, the epithelial cells of the epididymis and sperm. It has been reported that male reproductive tract CD52 induces antibodies interfering with sperm function and causes infertility. CD52 is also expressed in ovulated cumulus cells in female reproductive tissues. In the present study, we examined the distribution and the mechanism of regulation of CD52 in the uterus. CD52 expression was evaluated in uterine tissue recovered at 0.5, 4.5, 8.5 and 12.5dpc (days post-coitum). Immunohistochemistry, RT-PCR, Western blotting and gel shift analysis were performed to determine localization and transcriptional regulation of CD52. Cd52 mRNA and CD52 protein were found to increase simultaneously from 0.5 to 4.5dpc. Gel shift analysis revealed that NKX2.2, a transcriptional factor, binds to the promoter region of the Cd52 gene. CD52 and NKX2.2 were co-localized in the endometrium of the uterus. Pathway analysis using Ingenuity pathway analysis predicted that Cd52 is associated with genes involved in the formation of uterosomes which are necessary for embryo attachment. These findings suggest that CD52 synthesis is regulated by NKX2.2 at a transcriptional level, and that Cd52 may be a member of the network of genes regulating uterine receptivity for embryo implantation.

RESUMO

Recent emerging evidence suggests that ING family proteins play roles in carcinogenesis both as oncogenes and tumor suppressor genes depending on the family members and on cell status. Previous results from non-physiologic overexpression experiments showed that all five family members induce apoptosis or cell cycle arrest, thus it had been thought until very recently that all of the family members function as tumor suppressor genes. Therefore restoration of ING family proteins in cancer cells has been proposed as a treatment for cancers. However, ING2 knockdown experiments showed unexpected results: ING2 knockdown led to senescence in normal human fibroblast cells and suppressed cancer cell growth. ING2 is also overexpressed in colorectal cancer, and promotes cancer cell invasion through an MMP13 dependent pathway. Additionally, it was reported that ING2 has two isoforms, ING2a and ING2b. Although expression of ING2a predominates compared with ING2b, both isoforms confer resistance against cell cycle arrest or apoptosis to cancer cells, thus knockdown of both isoforms is critical to remove this resistance. Taken together, these results suggest that ING2 can function as an oncogene in some specific types of cancer cells, indicating restoration of this gene in cancer cells could cause cancer progression. Because knockdown of ING2 suppresses cancer cell invasion and induces apoptosis or cell cycle arrest, ING2 may be an anticancer drug target. In this brief review, we discuss possible clinical applications of ING2 with the latest knowledge of molecular targeted therapies.

RESUMO

BACKGROUND: Just two years after its inception, Japan's Long-term Care (LTC) insurance system is facing considerable criticism about whether or not it has developed a fair and appropriate way of allocating resources to the nation's disabled elderly population, especially those people with dementia. OBJECTIVE: The present study has investigated: (i) the relation of the Government-Certified Disability Index (GCDI) of the LTC insurance system to characteristics of people with dementia and their family caregivers; and (ii) whether the GCDI scores adequately reflect needs of people with DAT (dementia of Alzheimer's type) and VD (vascular-type dementia). METHODS: Subjects were assessed on their visits to outpatient clinics for their Activities of Daily Living (ADL), behavioural disturbances, MMSE, GCDI, service utilization and caregiver burden. Correlation analyses were conducted to examine the relationships among these variables, which were subsequently compared between the DAT and VD patients. RESULTS AND CONCLUSIONS: The GCDI was found to be associated with patients' ADLs and MMSE scores, and not with behavioural disturbances or caregiver burden. Compared to VD patients, people with DAT tended to have more behavioural disturbances but better ADL functioning. As a result, DAT patients were classified as 'less disabled' on their GCDI than VD patients, even though their caregivers felt as much burden as the caregivers of VD patients. These results show that the GCDI probably underestimates the impact of behaviour problems. Suggestions are made for a more balanced assessment of demented patients that is more consistent with their needs.

RESUMO

BACKGROUND: Although the anterior fibromuscular stroma (AFMS) comprises up to one third of the total bulk of the prostate, its physiological function remains unknown. We recently reported the possible contribution of the AFMS to micturition. The aim of this study is to reveal the differences in the distribution of innervation between the AFMS and the other regions of the prostate. METHODS: We performed immunohistochemical stainings using antibodies such as protein gene product (PGP) 9.5, tyrosine hydroxylase(TH), neuropeptide Y (NPY), and vasoactive intestinal peptide (VIP). Morphometric analysis was made to examine the density of peripheral nerve fibers containing PGP 9.5, TH, NPY, and VIP by using a computer-assisted imaging system. RESULTS: The number of PGP 9.5-immunoreactive (IR) nerve fibers and the smooth muscle in the AFMS decreased from the base to the apex of the prostate. TH-IR nerve fibers were more abundant in the AFMS than in the transition zone. NPY- and VIP-IR nerve fibers were less numerous in the AFMS than in the peripheral zone. CONCLUSIONS: This study is the first to demonstrate that the AFMS has peculiar neuronal innervation. We observed significantly different innervation in the AFMS compared with the other regions of the prostate.

RESUMO

Red soft coral (RSC; Dendronephthya nipponica, a marine coelenterate) causes spiny lobster fishermen living along the Pacific coast of Miyazaki Prefecture in Japan to develop occupational allergies, such as conjunctivitis, rhinitis, dermatitis and bronchial asthma. The aim of this study was to purify and to characterize RSC allergen, which causes occupational asthma in spiny lobster fishermen. The allergic responsiveness of spiny lobster fishermen to RSC was examined. The examinations included specific IgE production, skin test responses, lymphocyte stimulation tests and specific IgG production. We found that RSC has a strong sensitizing activity in humans at a molecular weight of 10 kD or more, while it has no IgE-producing activity at a molecular weight of less than 10 kD. Neither the nonatopic controls nor the atopic non-coral-allergic controls exhibited any RAST-binding activity to any fraction. For the purification and the identification of this new allergen component, repeated gel filtration of the RSC extract was performed on a Sephacryl S-200 column, followed by gel filtration on a Superose-6 column. The purified major allergen component Den n 1, which is separated on a Mono-Q column, showed intradermal responses, lymphocyte stimulating activity and specific IgG-producing activity in RSC-induced bronchial asthma patients. The 53-kD component was electroblotted on a polyvinylidene difluoride membrane. The N-terminal amino acid sequence of this new allergen component (Den n 1) was determined as Asp-Asp-Ile-Asn-Arg-Tyr-Ala-Phe-Asp-Asn-Lys-Ile-Asn- Asp-Lys-Leu-Phe-Asp-His-Trp-Gln-Ser.

RESUMO

A series of human nucleotide sugar transporters of the Golgi apparatus was recently cloned, including the transporters for UDP-galactose (UDP-Gal), UDP-N-acetylglucosamine (UDP-GlcNAc) and CMP-sialic acid (CMP-SA). We have examined the mRNA expression of these three transporters in human colon cancer tissues by reverse transcription-PCR analysis and compared it with that in nonmalignant colonic mucosa prepared from the same patients. The amount of mRNA for UDP-Gal transporter was significantly increased in colon cancer tissues compared with nonmalignant mucosa tissues (P = 0.035; n = 20). The increase was more prominent in patients with advanced colorectal cancer of Dukes' stages C and D, in which the amount of UDP-Gal transporter mRNA in cancer tissues showed on average about a 3.6-fold increase over the paired nonmalignant mucosa (statistically significant at P = 0.004; n = 14). The mRNA content of the other two transporters showed no significant difference between the paired cancer and normal tissues. When UDP-Gal transporter cDNA was stably transfected to cultured human colon cancer cells, the expression of Thomsen-Friedenreich (TF) antigen and of sialyl Lewis A (NeuAcalpha2-->3Galbeta1-->3[Fucalpha1-->4]GlcNAcbeta1-->R) and sialyl Lewis X (NeuAcalpha2-->3Galbeta1-->4[Fucalpha1-->3]GlcNAcbeta1-->R) determinants was significantly induced on transfectant cells, which resulted in markedly enhanced cell adhesion to vascular E-selectin. These findings suggest that the increase of UDP-Gal transporter mRNA is involved in the enhanced expression of cancer-associated carbohydrate determinants such as TF and sialyl Lewis A/X antigens in colon cancers.

RESUMO

STUDY OBJECTIVES: To investigate the roles of human alpha-defensin (HAD), human beta-defensin (HBD)-1, and HBD-2, novel antimicrobial peptides, in patients with Mycobacterium avium-intracellulare infection (MAI). PATIENTS: The study included 25 patients (10 men) with MAI who visited our hospital between June 1998 and August 1999. MEASUREMENTS AND RESULTS: In patients with pulmonary MAI, we measured HAD and HBD-1, and HBD-2 levels in plasma and in BAL fluid (BALF) by radioimmunoassay. Plasma concentrations of HAD and HBD-2 in those patients were higher than those in control subjects, whereas HBD-1 levels were similar to those in the control subjects. High levels of HAD and HBD-2, but not HBD-1, also were observed in the BALF of MAI patients. There was a positive correlation between HAD and interleukin (IL)-8 concentrations in the BALF of patients with MAI. BALF HBD-2 concentrations also correlated positively with those of plasma HBD-2 and BALF IL-1 beta in MAI patients. Patients with cavity formation on the chest roentgenogram had higher HAD and HBD-2 levels in their BALF than those of patients without cavity formation. Treatment with clarithromycin combined with two or three other antibiotics, including ethambutol, rifampicin, ofloxacin, or ciprofloxacin, for at least 6 months resulted in a significant fall in plasma HBD-2 concentrations in responders, but not in nonresponders. CONCLUSION: Our findings suggest that HAD and HBD-2 may participate in host defense and local remodeling of the respiratory tract in patients with MAI and that plasma HBD-2 levels may be a useful marker of disease activity in patients with pulmonary MAI.

RESUMO

We measured the levels of beta-defensin 1 and 2 (HBD-1, 2), novel antimicrobial peptides in plasma and in bronchoalveolar lavage fluid (BALF) from patients with with non-tuberculous mycobacterium infection (NTM). Plasma HBD-2 levels in NTM patients before treatment were higher than those in the controls, while the HBD-1 levels were similar to the control levels. High levels of HBD-2, but not of HBD-1, in BALF were also observed in NTM patients. In NTM, a positive correlation was found between HBD-2 levels in BALF and plasma, and also between HBD-2 and IL-1 beta levels in BALF. NTM patients with cavities or ectasia on chest radiography had higher HBD-2 levels in BALF than those without. Plasma HBD-2 levels in NTM patients were markedly decreased after successful treatment, while those of patients with an intractable mycobacterium infection maintained the same high plasma HBD-2 levels as those before treatment. These findings suggest that HBD-2 may participate in the host defense and plasma HBD-2 levels may reflect disease activity in pulmonary NTM.

RESUMO

We report a case of Paragonimus westermani infection with a reticulonodular lesion in the right lung, left pleural effusion, and a mobile subcutaneous mass. Analyses of pleural effusion and bronchoalveolar lavage fluid (BALF) showed marked eosinophilia and high levels of eosinophil cationic protein and interleukin (IL)-5. Transbronchial lung biopsy revealed the presence of pneumonia with mild eosinophilic infiltration but remarkable lymphocytic infiltration. In this patient, high IL-5 levels in both BALF and pleural effusion could explain the remarkable eosinophilia.
