    Full Text Available Abstract Background MI-319 is a synthetic small molecule designed to target the MDM2-P53 interaction. It is closely related to MDM2 antagonists MI-219 and Nutlin-3 in terms of the expected working mechanisms. The purpose of this study was to evaluate anti-lymphoma activity of MI-319 in WSU-FSCCL, a B-cell follicular lymphoma line. For comparison purpose, MI-319, MI-219 and Nutlin-3 were assessed side by side against FSCCL and three other B-cell hematological tumor cell lines in growth inhibition and gene expression profiling experiments. Results MI-319 was shown to bind to MDM2 protein with an affinity slightly higher than that of MI-219 and Nutlin-3. Nevertheless, cell growth inhibition and gene expression profiling experiments revealed that the three compounds have quite similar potency against the tumor cell lines tested in this study. In vitro, MI-319 exhibited the strongest anti-proliferation activity against FSCCL and four patient cells, which all have wild-type p53. Data obtained from Western blotting, cell cycle and apoptosis analysis experiments indicated that FSCCL exhibited strong cell cycle arrest and significant apoptotic cell death; cells with mutant p53 did not show significant apoptotic cell death with drug concentrations up to 10 μM, but displayed weaker and differential cell cycle responses. In our systemic mouse model for FSCCL, MI-319 was tolerated well by the animals, displayed effectiveness against FSCCL-lymphoma cells in blood, brain and bone marrow, and achieved significant therapeutic impact (p 28% (%ILS, 14.4 days increase in median survival days. Conclusion Overall, MI-319 probably has an anti-lymphoma potency equal to that of MI-219 and Nutlin-3. It is a potent agent against FSCCL in vitro and in vivo and holds the promises to be developed further for the treatment of follicular lymphoma that retains wild-type p53.

    Adverse effects of the GnRH antagonist Antide on folliculogenesis and fertility were noted when we were evaluating the therapeutic value of Antide on endometriosis in a rat model. Cyclic rats with (n = 56) and without (n = 18) surgically induced endometriosis received Antide (2 mg/kg) or vehicle at noon on days 0 (proestrus), 3, 6, and 9. Rats were killed at noon on days 0, 6, 12, 18, 24, 30, 42, and 165. The number of antral follicles and the number of atretic antral follicles evaluated did not differ (P greater than 0.05) between endometriosis and control rats. Antide-treated rats had more (P less than 0.05 ) atretic antral follicles (64.7%) than vehicle-treated rats (15.3%). Antide-treated rat ovaries contained fewer corpora lutea than those of vehicle-treated rats on days 6, 12, and 18. No corpora lutea were found in Antide-treated rat ovaries after day 18. The abnormal ovarian morphology of the Antide-treated rats persisted for the duration of the project (165 days). Fertility (rats without endometriosis) was assessed by mating vehicle-and Antide-treated rats at spontaneous proestrus (n = 8) for eight posttreatment cycles as well as after follicular stimulation (n = 2). All vehicle-treated and no Antide-treated rats became pregnant. No oocytes were found in the oviducts of Antide-treated rats after eight cycles, indicating that ovulation had not occurred. The serum FSH and estradiol concentrations in the rats treated with Antide were lower (P less than 0.05) on days 6, 12, and 18, but rose to values equal to (days 24 and 30) or greater than (day 42) those in vehicle-treated rats. Serum progesterone levels in rats treated with Antide were lower (P less than 0.05) than those in vehicle-treated rats on all days tested. In conclusion, at a dosage sufficient to suppress reproductive cyclicity (and elicit the regression of endometriosis), Antide also caused long term follicular atresia and infertility.

    Full Text Available A nonneutropenic patient with treated low-grade non-Hodgkin’s (Follicular lymphoma and secondary hypogammaglobulinemia recovered from pneumococcal pneumonia and septicemia (serotype 7F; ST191 subsequent to influenza A H1N1 (2009. Both infections were potentially vaccine preventable. The patient then developed pneumococcal meningitis due to a serotype 35F pneumococcus with a unique Multilocus Sequence Type (ST7004 which was not vaccine preventable. Patient management was influenced by host predisposition to pneumococcal infection, antibiotic intolerance, and poor response to polysaccharide pneumococcal vaccine. Indirect immunofluorescence with anti-human immunoglobulin confirmed a poor or intermediate response to Pneumovax II. Prophylactic erythromycin was initiated, and immunoglobulin transfusions were also commenced as a preventive strategy. ST7004 is a single locus variant of ST1635 which has been associated with the serotype 35F capsule in England. The spi gene in ST7004, which differentiates it from ST1635, is the same as the spi gene present in ST191 which could have arisen from the first disease episode suggesting that horizontal gene transfer may have occurred between different populations of pneumococci present within the patient in an attempt to evade vaccination selection pressure.

    In contrast to adolescent acne, infantile acne (IA) is a rare condition with only a limited body of available literature. In this descriptive, retrospective study, we reviewed six cases from 2002 to 2010 treated with oral isotretinoin. The average age of onset was 6.16 months (range 0-21 mos......). Consistent with the previous, limited literature, we found predominantly boys are affected, a predilection for the cheeks, and a polymorphic inflammatory morphology. Two patients had a family history of acne. All cases were successfully and safely treated with oral isotretinoin. The suggested treatment...... of childhood acne is similar to that of adolescents (graded according to the severity of the skin disease and risk of scarring). Oral isotretinoin appears to be an effective and safe treatment for severe IA....

    Full Text Available Temporal triangular alopecia (TTA, also known as congenital triangular alopecia, is a nonscarring, noninflammatroy, circumscribed form of alopecia. TTA has been associated with several disorders, such as Phakomatosis Pigmentovascularis. Hair restoration surgery using follicular unit transplantation has been a successful treatment modality for TTA. Herein we report such a success that was sustained for over six years.

    The multikinase inhibitor sunitinib (S) seems to have promising potential in the treatment of thyroid cancer. We focused on the impact of S and/or irradiation (R) on mechanisms of apoptosis in follicular thyroid cancer cells. The effects of R, S and their combination were evaluated 2 and 4 days after treatment, using the human thyroid cancer cell line CGTH W-1. The transcription of genes involved in the regulation of apoptosis was investigated using quantitative real-time PCR. Western blot analyses of caspases and survivin were also performed. S elevated BAX (day 4), CASP9, CASP3, BIRC5 (day 4) and PRKACA (day 4) gene expression, whereas the mRNAs of BCL2, CASP8, PRKCA, ERK1, and ERK2 were not significantly changed. S, R and R+S clearly induced caspase-9 protein and elevated caspase-3 activity. Survivin was down-regulated at day 4 in control cells and the expression was blunted by S treatment. R+S induced survivin expression at day 2 followed by a reduction at day 4 of treatment. Sunitinib and the combined application with radiation induced apoptosis in follicular thyroid cancer cells via the intrinsic pathway of apoptosis. In addition, sunitinib might induce apoptosis via decreased expression of the anti-apoptotic protein survivin. These findings suggest the potential use of sunitinib for the treatment of poorly differentiated follicular thyroid carcinomas.

    Full Text Available Abstract The objective of this study was to compare letrozole-stimulated cycles to natural cycles in 208 patients undergoing intrauterine insemination (IUI between July of 2004 and January of 2007. Group I (n = 47 received cycle monitoring only (natural group, Group II (n = 125 received letrozole 2.5 mg/day on cycle days three to seven, and Group III (n = 36 received letrozole 5 mg/day on cycle days three to seven. There were no differences between the groups in endometrial thickness or P4 on the day of hCG. Estradiol levels had higher variation in the second half of the follicular phase in both letrozole-treated groups compared to the control group. Estradiol per preovulatory follicle was similar in both letrozole cycles to that observed in the natural cycles. LH was lower on the day of hCG administration in the letrozole 2.5 mg/day group vs. the natural group. In summary, letrozole results in some minor changes in follicular, hormonal and endometrial dynamics compared to natural cycles. Increased folliculogenesis and pregnancy rates were observed in the letrozole-treated groups compared to the natural group. These findings need to be confirmed in larger, prospective studies.

    Full Text Available A case of a canine oral eosinophilic granuloma in a 14-year-old female crossbred is described. The dog was presented with a history of ptyalism, halitosis, local pain, decreased appetite, and blood staining noted on food and water bowls. Clinical, hematologic, and biochemical examinations, abdominal ultrasonography, and 3-view chest radiographs were performed, and no metastases were found. Histopathologic examination of two 6 mm punch biopsies from the oral lesion revealed the presence of eosinophilic granulomatous lesions in the submucosa. After treatment with corticosteroids and wide spectrum antibiotics no significant changes in clinical signs and lesion size were observed. Electrochemotherapy (ECT, a novel tumor treatment routinely used for cutaneous and subcutaneous tumors in human patients in the European Union since 2006, was used to treat the eosinophilic granuloma. The procedure was performed under general anesthesia, followed by intravenous administration of bleomycin. Six weeks after treatment a complete response with disappearance of the mass and improvement of clinical signs were observed.

    The objective of this study was to determine the effect of additional human chorionic gonadotrophin (hCG) on the ovarian response of gilts previously treated with 200 IU hCG combined with 400 IU equine chorionic gonadotrophin (eCG) (eCG/hCG). Seventy-one prepuberal gilts (105 ± 7.5 kg) were assigned to groups: i) eCG/hCG (hCG-0; n = 25); ii) eCG/hCG followed by 100 IU of hCG at 24 h (hCG-100; n = 24); iii) eCG/hCG followed by 200 IU hCG at 24 h (hCG-200; n = 10); and iv) controls (CON; n = 12). Ovulation response was assessed by ovarian dissection or real-time ultrasonography. Additional hCG did not significantly improve numbers of gilts ovulating. Numbers of corpora lutea increased with hCG, and was higher in hCG-200 (P hCG-0, the frequency of cysts in gilts was higher in hCG-100 (P hCG-200 (P hCG. We conclude that supplemental hCG will increase the number of corpora lutea but will be associated with follicular cyst development in a dose dependent manner.

    It is known that voiding difficulties can be caused by some drugs, but little is known about the role about the route of administration, especially in children. We report here a case of a 3-year old Italian boy referred to the Pediatric Emergency Unit complaining of two episodes of acute urinary retention, both after therapy with oral salbutamol. In spite of recommendations to use inhaled salbutamol to treat acute wheezing, oral salbutamol is still sometimes used in some settings. Whereas other side effects of systemic salbutamol are described in children, to our knowledge this is the first description of acute urinary retention as an adverse drug reaction to oral salbutamol.

    Full Text Available Oral cancer is one of the usual causes of mortality all over the world, with a five-year survival rate of only 50%. Oral cancers are treated primarily by surgery with / without adjuvant radiotherapy and / or chemotherapy. However, there is significant post-treatment morbidity and mortality secondary to recurrences. Dietary supplements like fruits and vegetables are rich in phytochemicals and provide a variety of antioxidants like vitamin A, C, E. Spirulina, Selenium, Green tea (EGCG, Neem, Tomatoes (lycopene, Turmeric (curcumin, and some medicinal mushrooms are also used as chemopreventive and chemotherapeutic agents. This overview emphasizes on natural therapies to fight against oral cancer. Thus, there are several natural compounds that can enhance the prevention of oral cancer.

    Four patients who complained of an inexplicable pruritus of several weeks to several years in duration are presented. General medical studies were unremarkable and the skin was normal except for erythematous papular lesions at sites recently scratched. The skin changes could be reproduced by multiple firm strokes with the broad edge of a tongue blade. The transitory, discrete, follicular, urticarial papules so elicited have been labeled by us as follicular dermographism. It is an entity to be distinguished from cholinergic and aquagenic urticaria. We postulate that follicular dermographism occurs during periods of transient antigenemia. At such times, the frictional force of scratching or the tongue blade test releases antigen from the blood stream to trigger focal urticaria at sites of high density mast cells, namely around the hair follicle. Hydroxyzine is an effective therapy.

    The effect of gonadotropin releasing hormone (GnRH) treatment on the time of ovulation and the occurrence of follicular dominance during the non-breeding and breeding seasons (experiment 1), and on fertility after artificial insemination (AI) in the non-breeding season (experiment 2), was examined in Merino ewes. Oestrus was synchronized in 40 nulliparous ewes (experiment 1; n = 20, in the non-breeding and breeding seasons) and in 79 multiparous ewes (experiment 2) using intravaginal sponges and pregnant mare serum gonadotropin. Thirty six hours after sponge removal (SR), half the ewes were injected (i.m.) with 40 microg of synthetic GnRH and the remainder used as controls. GnRH improved the synchrony of ovulation compared with the controls in the breeding (SD = 2.8 vs 5.7 days, p = 0.04) but not the non-breeding season (SD = 3.8 vs 4.4 days, p = 0.69), with ewes ovulating from 42 to 54 h (mean 50.4 +/- 4.08 h) and 42-60 h (mean 54.4 +/- 5.47 h) after SR for GnRH and control, respectively. For both treated and control ewes, ovulation occurred earlier in the non-breeding than the breeding season (50.1 vs 54.6 h; p = 0.002). GnRH had no effect on follicular dominance, as assessed by divergence (D: the time the ovulatory follicle exceeded the average size of the other non-ovulating follicles) or on the interval from D to ovulation (IDO). However, follicular dynamics differed between seasons. The mean follicle diameter increased at a faster rate up to 36 h after SR in the non-breeding compared with the breeding season and then rapidly declined, compared with a later peak (42 h after SR) in mean follicular size during the breeding season. IDO was shorter in the non-breeding than in the breeding season (26.7 +/- 4.30 h vs 39.6 +/- 4.53 h; p = 0.05). In experiment 2, ewes (n = 38 GnRH-treated, n = 40 controls) were inseminated in the uterus by laparoscopy 42 h or 48 h after SR with frozen-thawed sperm. The fertility of ewes treated with GnRH (nine of 39, 23%) was not

    Patients treated with oral anticoagulants have increased susceptibility to bleeding, and therefore any surgical medical procedure and especially oral surgery requires a therapeutic approach that minimizes bleeding effects in these patients. The working hypothesis was based on studies of local application of tranexamic acid after maxillofacial interventions as effective therapeutic alternative for the prevention and control of bleeding. The aim was to assess the effectiveness of the application of a gel solution tranexamic acid after tooth extraction in anticoagulated patients in terms of healing time and degree of healing. The results indicate that application of tranexamic acid gel is very effective for consistency and maintenance in the place of action and shows its efficacy as a procoagulant material. The application of a gel solution of tranexamic acid in oral anticoagulants patients ameliorates healing time and the bleeding time within the first 48-72 h. Copyright © 2013 Elsevier España, S.L.U.

    To present our experience in treating vascular malformations in the oral cavity solely by injecting ethanol into the lesions. We treated 26 patients (12 men and 14 women) with oral malformations. The diagnosis was based on clinical findings (n=26), magnetic resonance imaging studies (n=19), angiography findings (n=5), and direct puncture venography (n=2). To achieve sclerosis, we administered absolute ethanol through direct puncture. All interventions were performed under deep sedation. The vascular malformations treated ranged from 7mm to 60mm (median: 24.5mm) in maximum diameter and had been present in the oral cavity for 0.2 to 54 years (mean: 13.6 years). The median age of the patients was 44.5 years (range: 12-87 years). The reason for treatment of the malformation was: an increase in size (n=8), local bleeding (n=11), risk of bleeding during dental extraction (n=5), pain (n=1), and esthetic purposes (n=3). Lesions were located in the mucosa of the cheek (n=12), in the facial gingiva (n=5), in the labial mucosa (n=6), in the tongue (n=3), in the pterygomandibular region (n=1), and in the palate (n=1). The median dose of ethanol was 3.2mL. Twenty lesions disappeared after a single injection session, five after two sessions, two after three sessions, and one after five sessions. In 20 cases all signs of the lesions disappeared, in 6 a bluish macule persisted, and in 2 a mass effect persisted. The symptoms improved in all patients. Only transient complications of sclerotherapy were observed: local inflammation, perioral paresthesia in two patients, and necrosis of the mucosa of the cheek in one. Alcohol sclerotherapy is an efficacious procedure for treating vascular malformations in the oral cavity. Copyright © 2011 SERAM. Published by Elsevier Espana. All rights reserved.

    Three experiments were conducted to: (1) compare the effect of three oestradiol formulations on gonadotrophin release in ovariectomised cows; (2) compare the effects of either oestradiol-17beta (E-17beta) or oestradiol benzoate (EB), given at two doses, on the synchrony of ovarian follicular wave emergence in CIDR-treated beef cattle; and (3) determine the timing of ovulation of the dominant follicle of a synchronised follicular wave following administration of E-17beta or EB 24h after progesterone withdrawal. In Experiment 1, ovariectomised cows (n = 16) received a once-used CIDR on Day 0 (beginning of the experiment) and were allocated randomly to receive 5mg of E-17beta, EB or oestradiol valerate (EV) plus 100mg progesterone i.m. The CIDR inserts were removed on Day 7. There were effects of time, and a treatment-by-time interaction (P cattle, and the interval from CIDR removal to ovulation did not differ in heifers given either E-17beta or EB 24h after CIDR removal.

    Oral rehydration solution (ORS) is used to treat dehydration caused by diarrheal diseases including cholera. Reduced osmolarity formulations are safe and more effective than standard ORS for treating non-cholera diarrhea. As cholera causes rapid electrolyte loss, it is important to know if these benefits are similar for people with cholera. To compare the safety and efficacy of reduced osmolarity oral rehydration solution (ORS) with standard ORS for treating diarrhea due to cholera. We searched the Cochrane Infectious Disease Group Specialized Register (January 2004), CENTRAL (The Cochrane Library Issue 1, 2004), MEDLINE (1966 to January 2004), EMBASE (1974 to January 2004), and LILACS (1982 to January 2004). We also contacted organizations and searched reference lists. Randomized controlled trials comparing reduced osmolarity ORS with standard ORS for treating adults and children with acute diarrhea due to cholera. Two reviewers independently applied eligibility criteria, assessed trial quality, and extracted data. We pooled binary data using relative risks (RR), continuous data using weighted mean difference (WMD) or the standardized mean difference (SMD), and presented the results with 95% confidence intervals (CI). For glucose-based reduced osmolarity ORS, seven trials (718 participants) met the inclusion criteria. Biochemical hyponatremia (serum sodium cholera, reduced osmolarity ORS is associated with biochemical hyponatremia when compared with standard ORS, although there are similar benefits in terms of other outcomes. Although this risk does not appear to be accompanied by serious consequences, the total patient experience in existing trials is small. Under wider practice conditions, especially where patient monitoring is difficult, caution is warranted.

    Many psychotropic medications affect oral health. This review identified oral side effects for antidepressant, antipsychotic, anticonvulsant, antianxiety and sedative drugs that are recommended in Australia for the management of common mental illnesses and provides recommendations to manage these side-effects. The Australian Therapeutic Guidelines and the Australian Medicines Handbook were searched for medications used to treat common mental health conditions. For each medication, the generic name, class, and drug company reported side-effects were extracted from the online Monthly Index of Medical Specialties (eMIMs) and UpToDate databases. Meyler's Side Effect of Drugs Encyclopaedia was used to identify additional oral adverse reactions to these medications. Fifty-seven drugs were identified: 23 antidepressants, 22 antipsychotics or mood stabilisers, and 12 anxiolytic or sedative medications. Xerostomia (91%) the most commonly reported side effect among all classes of medications of the 28 identified symptoms. Other commonly reported adverse effects included dysguesia (65%) for antidepressants, and tardive dyskinesia (94%) or increased salivation (78%) for antipsychotic medications. While xerostomia has often been reported as a common adverse effect of psychotropic drugs, this review has identified additional side effects including dysguesia from antidepressants and tardive dyskinesia and increased salivation from antipsychotics. Clinicians should consider oral consequences of psychotropic medication in addition to other side-effects when prescribing. For antidepressants, this would mean choosing duloxetine, agomelatine and any of the serotonin re-uptake inhibitors except sertraline. In the case of antipsychotics and mood stabilisers, atypical agents have less oral side effects than older alternatives. Copyright © 2017 Elsevier B.V. All rights reserved.

    The CO2 laser has been used by our group as a secure and efficient tool for the treatment of symptomatic oral cavity hemangiomas which can be responsible for disturbance for swallowing, phonation and in hygienic, besides discomfort and bleeding to patients. During the last four years, twelve patients with symptomatic oral cavity hemangioma were treated at the Laser Unit of our University. The treatment consisted in the application of CO2 laser at medium to low intensity according to characteristics and location of the lesions. For hemangiomas located at sites of easy surgical access such as anterior 1/3 of the tongue, lips, bucal vestibule we use 10 to 37 J/mm2 over the surface of the lesion. When the hemangioma was located at difficult surgical access sites, such as, tonsils, posterior 1/3 of tongue, or at pharyngeal wall we used 3.0 to 4.0 J/mm2 encircling the whole hemangioma. This causes reduction in the size of the lesion throughout sclerosis of nutrition vessels. After this initial procedure we applied 0.8 to 1.0 J/mm2 over the whole extent of the lesion. For both procedures we observed no significant bleeding or inflammatory reaction. The patients referred minimal post-operative discomfort with good cicatricial evolution. The evident reduction in the vascularization and size could be confirmed by photographic documentation. The good results described above, with disappearance of symptoms lead to the conclusion that CO2 laser is an efficient and secure method of treatment for symptomatic hemangioma of the oral cavity.

    A 65-year old man was admitted due to protracted gum bleeding after dental surgery. The peripheral blood smear showed thrombocytosis(1,160,000/mm/sup 3/) with bizarre, giant platelets. The paltelet adhesiveness revealed 28% (normal control 31-85%) by Salzman method and the platelet aggregation revealed moderately delayed response to collagen, but normal responsiveness to A.D,P, and no responsiveness to epinephrine, the spleen scan(sup(99m)Tc-NaTcO/sub 4/) showed the finding of splenic infraction. The gum bleeding ceased after transfusion of 8 units of platelet rich plasma, and he was treated with oral sup(32)P(2.5mCi/m/sub 2/) under the diagnosis of essential thrombocythemia. The platelet count returned toward normal 2 months after treatment, and he was in good healthy condition.

    Full Text Available Lichen striatus (LS is an uncommon dermatosis of unknown etiology that presents as a continuous or interrupted linear band of pink, tan, red or skin-colored papules in a blaschkoid distribution. The lesions are generally solitary and unilateral, but unusual extensive cases with multiple and bilateral lesions have been also described. Albeit LS is typically an asymptomatic and self-limited dermatosis, it may cause a significant psychological distress in some patients, thus requiring an appropriate therapy. Topical steroid is the most commonly used treatment but it is not always effective. We report a case of LS unresponsive to topical steroid therapy associated with psoriasis vulgaris successfully treated with oral acitretin.

    The increasing number of cancer survivors the past decades, has sparked the need for fertility preservation strategies. Due to predominantly ethical constraints, human research material is scarce. A bovine in vitro model is a valuable alternative. Therefore, the following objectives were defined: 1) to xeno-graft bovine ovarian cortex tissue in immune deficient mice as a study-model for female fertility preservation strategies; 2) to stereologically quantify vascularization in Vascular Endothelial Growth Factor (VEGF)-treated and non-treated tissue; 3) to study preantral follicular survival in situ, after xenotransplantation. Bovine ovarian tissue strips were incubated with or without VEGF prior to grafting into female, neutered BALB/c-nu mice (n=16). Non-transplanted cortical tissue was used as a control. At time zero (control), two (2 weeks) and four (4 weeks) weeks after transplantation, grafts were retrieved and assessed by von Willebrand Factor and caspase-3 immunostaining. Data were analyzed using a linear mixed model. In the VEGF+ grafts, 31% of the follicles were considered 'alive' 2 weeks after transplantation, compared to only 17% in the VEGF- grafts (P<0.05). However, no difference could be detected 4 weeks after transplantation (P=0.76) with less follicles being considered 'alive' after transplantation (22%), compared to the control (47.5%) (P<0.05). Finally, the vascular surface density was significantly less in the grafts, irrespective of the transplantation period or the use of VEGF. Although the transplantation process overall negatively influenced the number of viable follicles and vascular density, VEGF exposure prior to transplantation can favor follicle survival during a 2 weeks transplantation period.

    Full Text Available Vitamin K antagonists (VKA are among the most widely prescribed drugs in the industrialized world. In fact, for decades, VKA have been the only orally available anticoagulant for the primary and secondary prevention of venous and arterial thrombotic events. Their efficacy has been widely demonstrated in a series of studies carried out in the 1990s. Since the incidences of atrial fibrillation and venous thromboembolism increase exponentially with age, the number of anticoagulated patients is destined to increase. This paper examines anticoagulation therapy management with particular attention to the use of VKA.

    2012-05-01

    Oral lichen planus (OLP) is a common chronic inflammatory disease associated with cell-mediated immunological dysfunction. Symptomatic OLP is painful and complete healing is rare. The aim of this review was to assess the evidence for the efficacy and safety of treatments for symptomatic OLP. The Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE were searched in January 2011 to identify all randomized controlled trials (RCTs) evaluating any intervention for the treatment of symptomatic OLP. A total of 28 trials were included in this Cochrane review. There was no evidence from three RCTs that topical pimecrolimus is better than placebo in reducing pain from OLP. There was weak evidence from two RCTs that topical aloe vera may be associated with a reduction in pain compared with placebo. There was weak and unreliable evidence from two small trials, at high risk of bias, that topical ciclosporin may reduce pain and clinical signs of OLP. There was no evidence (from five trials each evaluating a different steroid and/or calcineurin inhibitor) that there is a difference between treatment with topical corticosteroids (TCSs) compared with topical calcineurin inhibitors with regard to reducing pain associated with OLP or that any specific steroid therapy is more or less effective at reducing pain. Although TCSs are considered to be the first-line treatment, we did not identify any RCTs that compared TCSs with placebo in patients with symptomatic OLP. From the 28 trials included in this systematic review, the wide range of interventions compared means there is insufficient evidence to support the superior effectiveness of any specific treatment.

    In this study, we have established an oral phage cocktail therapy in adult mice model and also performed a comparative analysis between phage cocktail, antibiotic and oral rehydration treatment for orally developed Vibrio cholerae infection. Four groups of mice were orally infected with Vibrio cholerae MAK 757 strain. Phage cocktail and antibiotic treated groups received 1×10(8) plaque forming unit/ml (once a daily) and 40mg/kg (once a daily) as an oral dose respectively for consecutive three days after bacterial infection. In case of oral rehydration group, the solution was supplied after bacterial infection mixed with the drinking water. To evaluate the better and safer approach of treatment, tissue and serum samples were collected. Here, phage cocktail treated mice reduced the log10 numbers of colony per gram by 3log10 (p0.05). Besides, it was evident that antibiotic and phage cocktail treated group had a gradual decrease in both IL-6 and TNF-α level for 3 days (pcholera ciprofloxacin was found to be a better antimicrobial agent, but from the safety and specificity point of view, a better method of application could fill the bridge and advances the phages as a valuable agent in treating Vibrio cholerae infection.

  15. Follicular penetration and targeting.

    In the past, intercellular penetration was assumed to be the most important penetration pathway of topically applied substances. First hints that follicular penetration needs to be taken into consideration were confirmed by recent investigations, presented during the workshop "Follicular Penetration and Targeting" at the 4th Intercontinental Meeting of Hair Research Societies", in Berlin 2004. Hair follicles represent an efficient reservoir for the penetration of topically applied substances with subsequent targeting of distinct cell populations, e.g., nestin-expressing follicular bulge cells. The volume of this reservoir can be determined by differential stripping technology. The follicular penetration processes are significantly influenced by the state of the follicular infundibulum; recent experimental investigations could demonstrate that it is essential to distinguish between open and closed hair follicles. Topically applied substances can only penetrate into open hair follicle. Knowledge of follicular penetration is of high clinical relevance for functional targeting of distinct follicular regions. Human hair follicles show a hair-cycle-dependent variation of the dense neuronal and vascular network. Moreover, during hair follicle cycling with initiation of anagen, newly formed vessels occur. Thus, the potential of nestin-expressing hair follicle stem cells to form neurons and blood vessels was investigated.

    The present retrospective cohort study was conducted to investigate whether serum anti-Müllerian hormone (AMH) levels, determined by either the Immunotech (IOT) or the second generation (Gen II) assay, can predict follicular recruitment in women with polycystic ovary syndrome (PCOS) undergoing ovulation induction with clomiphene citrate (CC). Patients received 50 mg CC daily for ovulation induction followed by natural intercourse or intrauterine insemination. Overall, 84 women had their serum AMH levels tested before treatment [42 patients with Immunotech (IOT), and 42 patients with the Gen II assay]. The primary outcome was to determine dominant follicle (>10 mm) recruitment in relation to AMH levels. Thirty-three (79%) patients in the IOT and 34 (81%) patients in the Gen II assay group developed a dominant follicle within 15 days after initiation of CC. Circulating AMH levels did not differ between women with or without dominant follicular recruitment in the both groups. By using either the AMH IOT or the Gen II assay, serum AMH levels were not predictive of the development of a dominant follicle. In conclusion, serum AMH levels measured by IOT or Gen II assay, has limited value to predict PCOS patients who will develop a dominant follicle following ovulation induction with CC.

    Full Text Available Follicular occlusion tetrad is a symptom complex consisting of four conditions having a similar pathophysiology. It includes Hidradenitis suppurativa, acne conglobata, dissecting cellulitis of the scalp and pilonidal sinus. The exact pathogenesis of this group of disease is unknown but evidence suggests that they share the same pathological process initiated by follicular occlusion in apocrine gland bearing areas. Though each of these conditions is commonly encountered singly, follicular occlusion tetrad as a symptom complex has been rarely reported in the literature.

    Bezoars are concretions of foreign bodies found in the gastrointestinal tract. In the past, most common method for the treatment of bezoar was surgical management. However, the current treatment methods include chemical dissolution and endoscopic mechanical lithotripsy. There were few reports on the treatment of phytobezoars by nasogastric Cola lavage. However, there was no report succeeded by oral route alone. In our two cases, phytobezoars were treated by oral administration of Coca-Cola. Our patients drank 700-800 mL of Coca-Cola daily, and after two months, complete dissolutions of bezoars were achieved. We report two cases of phytobezoars completely treated by drinking Coca-Cola.

    Bisphosphonates inhibit bone resorption and are used to treat a range of pathologies, including Paget disease, osteoporosis, multiple myeloma and metastases associated with breast or prostate cancer. At present, there is no effective treatment for bisphosphonate induced osteonecrosis, so prevention is extremely important. Since quality of life deteriorates for those suffering osteonecrosis, maximum precautions should be taken with patients at risk, and especially whenever oral surgery, including dental implant placement, is contemplated. Dentists and oral or maxillofacial surgeons must keep up to date with the latest approaches to prevention, particularly when treating patients who are presently taking, or who will be taking bisphosphonates and are also candidates for dental implants.

    There are significant levels of dental caries in Australian school-aged children, with children aged five years having a mean dmft of 1.3. It has also been identified that, in general, oral health clinicians lack confidence to treat very young children and this study aimed to increase capacity of public sector oral health clinicians to treat preschool children. An educational program was developed, implemented and evaluated for its capability to increase the confidence and knowledge of oral health clinicians and dental assistants in providing oral care for children aged 12 months to 5 years. In 2011 and 2012, the course was delivered to 36 clinicians (22 dentists, 12 dental therapists, and two oral health therapists) and showed increases in their confidence and knowledge for participants when providing dental procedures to preschool children. The educational program that was developed and implemented has met its objective of increasing the knowledge and confidence of practicing oral health clinicians and dental assistants in the management of preschool children. Strategies to further enhance the outcomes of this educational program have been proposed.

  3. To treat...or not to treat? Clinicians' views on the management of oral potentially malignant disorders.

    2015-12-01

    Oral potentially malignant disorders (PMD) are recognisable mucosal conditions that have a variable and unpredictable risk of transformation to invasive squamous cell carcinoma (SCC). Modern management relies initially on clinical recognition of suspicious lesions and histopathological assessment and grading after incisional biopsy. However, it then varies from wide excision to observation and review, and depends not only on the severity of dysplasia but also on the clinician's preference as there is no high-level evidence to support best practice. We invited clinicians from oral and maxillofacial surgery, oral medicine, ear, nose, and throat (ENT), and plastic surgery, to complete an online questionnaire on current practice, which included 3 fictitious cases, to ascertain their views on the management of PMD and to find out whether they would be interested in becoming involved in a proposed future randomised controlled trial (RCT). Of the 251 who replied, 178 (71%) were oral and maxillofacial surgeons, and 99 (39%) expressed an interest in participating in a future RCT. Most respondents (n=164 or 99%) would always treat severely dysplastic lesions by excision or laser ablation, whereas only 8% (n=13) would always excise mild dysplasia. The greatest equipoise among those interested in taking part in a RCT was found in the case of moderate dysplasia for which 27% (n=27) favoured observation compared with surgical excision or laser ablation. This study shows that there is support for a multicentre, prospective RCT that compares observation with resection and laser ablation in patients with moderate dysplasia.

    2016-09-01

    Although acne is not an infectious disease, oral antibiotics have remained a mainstay of treatment over the last 40 years. The anti-inflammatory properties of oral antibiotics, particularly the tetracyclines, are efficacious in treating inflammatory acne lesions. Common prescribing practices in Dermatology exert significant selection pressure on bacteria, contributing to the development of antibiotic resistance. Antibiotic use for acne not only promotes resistance in Propionibacterium acnes, but also affects other host bacteria with pathogenic potential. This review will summarize the commonly used treatments for acne vulgaris, and how they should be combined as rational treatment. The indications for using oral antibiotics in acne will be highlighted. Strategies described in the literature to conserve the utility of oral antibiotics will be summarized. These include limiting the duration of antibiotic therapy, concomitant use of a topical non-antibiotic agent, use of subantimicrobial dose doxycycline, and the introduction of topical dapsone.

    Follicular dendritic cell sarcoma is a rare neoplasm that originates from follicular dendritic cells in lymphoid follicles. This disease usually involves the lymph nodes, and especially the head and neck area. Rarely, extranodal sites may be affected, including tonsil, the oral cavity, liver, spleen and the gastrointestinal tract. We report here on the imaging findings of follicular dendritic cell sarcoma of the abdomen that involved the retroperitoneal lymph nodes and colon. It shows as a well-defined, enhancing homogenous mass with internal necrosis and regional lymphadenopathy.

    Full Text Available Aims and Objectives: To compare the autofluorescence spectra of oral submucous fibrosis (OSF with normal mucosa, the autofluorescence spectra of OSF before and after treatment with intralesional dexamethasone and hyaluronidase, the clinical improvement following treatment with the changes in autofluorescence spectra and to prove that autofluorescence spectroscopy is a good method for diagnosis and assessment of treatment effectiveness in OSF. Materials and Methods: The study was conducted at the Department of Oral Medicine and Radiology, Tamilnadu Government Dental College and Hospital, Chennai and Division of Medical Physics and Lasers, Department of Physics, Anna University, Chennai in 20 patients seeking medical management for symptomatic OSF and 20 patients who had dental caries only without any oral mucosal diseases and oral habits were used as normal controls. Their ages ranged from 20 to 40 years, including both male and female. In vivo fluorescence emission spectra were obtained using a handheld optical fiber probe attached to a Fluoromax-2 spectrofluorometer. Results: The fluorescence spectrum of OSF had an intense fluorescence emission at 385 nm with a secondary emission peak at 440 nm compared with that of the normal oral mucosa. The average fluorescence spectrum of the post treated OSF mucosa had a lesser intensity around 385 nm and a higher intensity around 440 nm than that of the pre treated OSF mucosa, thereby mimicking the normal oral mucosa. All the three clinical parameters (maximal mouth opening, tongue protrusion and the severity of burning sensation showed a high statistical significance, with P < 0.001, as in the case of classification of pre treated OSF mucosa from the post treated OSF mucosa using the autofluorescence technique. Conclusion: The change in the fluorescence emission spectrum for both normal and OSF mucosa before and after treatment can be explained by analyzing the changes in the fluorescence intensity of

    The objective of the current study was to determine the effects of hormonal treatments on ovarian follicular development and oocyte quality in anestrous ewes. Multiparous crossbred (RambouilletxTarghee) ewes were given melatonin implants (MEL) and/or controlled internal drug release (CIDR) devices in conjunction with follicle stimulating hormone (FSH) during anestrus (March-May). In Experiment 1, ewes (n=25) were assigned randomly to four groups (n=4-7/group) in a 2x2 factorial arrangement [+/-MEL and +/-CIDR], resulting in Control (no treatment), CIDR, MEL, and MEL/CIDR groups, respectively. Ewes received an implant containing 18 mg of melatonin (Melovine) on Day 42 and/or a CIDR from Days 7 to 2 (Day 0: oocyte collection). In Experiment 2, ewes (n=12) were assigned randomly to two groups (n=6/group; 1CIDR or 2CIDR) and received the same type of melatonin implant on Day 60. All ewes received a CIDR device from Days -22 to -17 and 2CIDR ewes received an additional CIDR device from Days -10 to -2. In both experiments, ewes were given FSH im twice daily (morning and evening) on Days -2 and -1 (Day -2: 5 units/injection; Day -1: 4 units/injection). On the morning of Day 0, ovaries were removed, follicles>or=1 mm were counted, and oocytes were collected. Thereafter oocytes were matured and fertilized in vitro. In Experiment 1, the number of visible follicles and the rates of oocyte recovery and in vitro maturation were similar (P>0.10) for Control, CIDR, MEL and MEL/CIDR (overall 29.7+/-2.9%, 89.9+/-7.1% and 95.0+/-2.0%, respectively). The rates of in vitro fertilization (IVF) were lower (P0.10) for 1CIDR and 2CIDR groups (overall 27.3+/-3.2%, 92.1+/-2.7% and 90.2+/-1.9%, respectively). However, the rates of IVF were lower (P<0.01) for 2CIDR than 1CIDR group (30.2% versus 58.0%, respectively). In summary, when treatment with P4 commenced only 2 d before oocyte collection, rates of IVF were reduced in both experiments. Therefore, progestin treatment protocols used in

    Objective: To broaden our knowledge of para-neoplastic autoimmune multi-organ syndrome (PAMS). Methods: A patient with PAMS associated with follicular lymphoma and bronchiolitis obliterans treated in our hospital was retrospectively analyzed and the clinical features of PAMS were reviewed. Results: A 49-year-old female patient suffered from painful ulcers in the oral cavity and vagina, dry cough and dyspnea. Imaging examinations suggested multiple lymph node enlargements. Inguinal lymph node biopsy revealed follicular lymphoma. Although the oral and vaginal ulcers went into remission with glucocorticoid and thalidomide therapy and follicular lymphoma gained partial remission with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone) chemotherapy, respiratory failure still progressed. Conclusion: PAMS should be considered in patients with unexplained oral mucosa ulcers and dyspnea, which didn't match with the chest image manifestations. Extensive work-up should be performed to find out the potential tumor after diagnosis of PAMS. Early diagnosis and complete removal of tumor were essential to PAMS treatment.

    Female Wistar rats at 21 days of age were treated with one of three concentrations of soy isoflavones (SIF) (50, 100 or 200 mg/kg body weight, orally, once per day) from weaning until sexual maturity (3 months) in order to evaluate the influence of SIF on ovarian follicle development. After treatment, the serum sex hormone levels and enumeration of ovarian follicles of the ovary were measured. The metabolic profile of follicular fluid was determined using HPLC-MS. Principal component analysis (PCA) and partial least-squares-discriminant analysis (PLS-DA) was used to identify differences in metabolites and reveal useful toxic biomarkers. The results indicated that modest doses of SIF affect ovarian follicle development, as demonstrated by decreased serum estradiol levels and increases in both ovarian follicle atresia and corpora lutea number in the ovary. SIF treatment-related metabolic alterations in follicular fluid were also found in the PCA and PLS-DA models. The 24 most significantly altered metabolites were identified, including primary sex hormones, amino acids, fatty acids and metabolites involved in energy metabolism. These findings may indicate that soy isoflavones affect ovarian follicle development by inducing metabolomic variations in the follicular fluid. - Highlights: ► Modest doses of soy isoflavones (SIF) do affect ovarian follicle development. ► SIF treatment-related metabolic alterations in follicular fluid were found. ► The 24 most significantly altered metabolites were identified.

The aim of this study was to investigate the potential of glyceryl monoolein (GMO cubosomes as lipid nanocarriers to improve the oral efficacy of AmB. Antifungal efficacy was determined in vivo in rats after oral administration, to investigate its therapeutic use. The human colon adenocarcinoma cell line (Caco-2 was used in vitro to evaluate transport across a model of the intestinal barrier. In vivo antifungal results showed that AmB, loaded in GMO cubosomes, could significantly enhance oral efficacy, compared against Fungizone®, and that during a 2 day course of dosage 10 mg/kg the drug reached effective therapeutic concentrations in renal tissue for treating fungal infections. In the Caco-2 transport studies, GMO cubosomes resulted in a significantly larger amount of AmB being transported into Caco-2 cells, via both clathrin- and caveolae-mediated endocytosis, but not macropinocytosis. These results suggest that GMO cubosomes, as lipid nanovectors, could facilitate the oral delivery of AmB.Keywords: glyceryl monoolein cubosomes, oral delivery, amphotericin B, antifungal activity, absorption mechanism

    Full Text Available Aim: Our aim is to determine the minimal cytopathologic criteria needed to make differential diagnosis in follicular-patterned lesions of the thyroid gland.Materials and Methods: We reviewed 56 fine needle aspiration cytology specimens which were reported as “suspicious for follicular-patterned lesions of thyroid” between years 2001 and 2005 in our hospital and their histological slides. Parameters for cytopathologic assesment are cellularity, colloid formation, multilayered rosette formation, follicular cell rings, monolayered sheets, intact follicles, hyperplastic papillae, hyaline stromal fragments, intranuclear inclusions, nuclear grooves, angulated nuclei, nucleoli, cerebriform nuclei, nuclear size, macrophages, flame cells and Hurthle cells. Statistical analysis was performed using χ2 and Fisher's-exact tests and Kolmogorov-Simirnov test.Results: Four cytopathologic features–cerebriform nuclei, angulated nuclei, nuclear grooves and intranuclear inclusion- were constantly observed in the follicular variant of papillary carcinoma (p< 0.05. Diluted colloid, monolayered sheet, nuclear size, macrophage and nucleoli were frequently seen in nodular hyperplasia (p< 0.05. The nuclear size was the sole differential cytopathologic criteria between follicular adenoma and follicular carcinoma (p<0.05.Conclusion: Detailed cytopathologic examination was found to be important in differentiating follicular variant of papillary carcinoma from nodular hyperplasia. On the other hand, none of the cytopathologic findings were sufficient to distinguish follicular adenoma from follicular carcinoma. Therefore, cytopathologists should report such lesions as “follicular neoplasms”.

    In developing countries where systemic antifungal are often unavailable, treatment of filamentous fungi infection as Fusarium is sometimes very difficult to treat. We report the case of a keratomycosis due to Fusarium oxysporum treated by povidone iodine eye drops and oral fluconazole. The diagnosis of abscess in the cornea was retained after ophthalmological examination for a 28-year-old man with no previous ophthalmological disease, addressed to the Ophthalmological clinic at the University Hospital Le Dantec in Dakar for a left painful red eye with decreased visual acuity lasting for 15 days. The patient did not receive any foreign body into the eye. Samples by corneal scraping were made for microbiological analysis and the patient was hospitalized and treated with a reinforced eye drops based treatment (ceftriaxone+gentamicin). The mycological diagnosis revealed the presence of a mold: F. oxysporum, which motivated the replacement of the initial treatment by eye drops containing iodized povidone solution at 1% because of the amphotericin B unavailability. Due to the threat of visual loss, oral fluconazole was added to the local treatment with eye drops povidone iodine. The outcome was favorable with a healing abscess and visual acuity amounted to 1/200th. Furthermore, we noted sequels such as pannus and pillowcase. The vulgarization of efficient topical antifungal in developing countries would be necessary to optimize fungal infection treatment. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Introduction Osteonecrosis of the jaw (MRONJ) linked to bisphosphonate treatment has specific characteristics that render its therapeutic management challenging for clinicians. Poor response to standard treatment makes it essential to take special precautions when treating this type of disease; therefore, antibiotic prophylaxis and/or antibiotic therapy have been proposed as effective and helpful tools in these situations. Objectives This article seeks to assess published evidence in order to evaluate the different protocols used for antibiotic prophylaxis and/or antibiotic therapy in the general context of patients treated with bisphosphonates. Material and Methods A literature review of the last 10 years was carried out in PubMed using the following keywords: “antibiotic prophylaxis and osteonecrosis,” “bisphosphonates AND osteonecrosis AND dental management,” “bisphosphonate AND osteonecrosis AND antibiotic prophylaxis AND oral surgery.” A total of 188 articles were obtained, of which 18 were ultimately selected. Results and Discussion In patients treated with oral and intravenous bisphosphonates without chemotherapy-associated osteonecrosis of the jaw, antibiotic prophylaxis prior to oral surgery is an important tool to avoid osteonecrosis and promote healing of the affected area. If the patient previously exhibited chemotherapy-associated osteonecrosis after tooth extraction, antibiotic prophylaxis is indicated to prevent recurrent osteonecrosis and promote healing of the extraction site. If chemotherapy-associated osteonecrosis is already present, antibiotic therapy is a vital part of conservative management to reduce the symptomatology of MRONJ and keep it from worsening. Finally, a lack of clinical data and randomized controlled trials makes it difficult to choose the most appropriate protocol for the various clinical situations studied.

    Full Text Available Follicular lymphoma(FL is the most common indolent non-Hodgkin lymphoma and constitutes 15% to 30% of lymphoma diagnoses. The natural history of the disease is characterized by recurrent relapses and progressively shorter remissions with a median survival of 10yrs. The impossibility of a chieving a definite cure, have prompted investigations into the possible role of more effective and less toxic strategies with innovative therapeutic agents.  Recently Casulo et al demonstrated that approximately 20% of patients with FL actually relapse within 2 years after achieving remission with R-CHOP and have a poor prognosis. It is conceivable that this particularly chemoresistant population would benefit from specifically targeting the biologic and genetic factors that likely contribute to their poor prognosis. Evolving strategies for difficult to treat FL patients have recently considered  immunomodulatory agents, new monoclonal antibodies as well as drugs targeting selective intracellular pathways. The importance of targeting the microenvironment together with the malignant FL cell has been particularly underscored. We review the most promising approaches, such as the combination of anti-CD20 antibodies with immunomodulatory drugs (Lenalidomide, with mAbs directed against other surface antigens such as CD22 and CD23 (epratuzumab, lumiliximab, with immunomodulatory antibodies such as PD-1, or with inhibitors of key steps in the B-cell receptor pathway signaling such as PI3K inibithors(idelalisib, duvelisib. Another highly attractive approach is the application of the bi-specific T-cell engaging (BiTE antibody blinatumomab which targets both CD19 and CD3 antigens. Moreover, we highlight the potential of these therapies,  taking into account their toxicity. Of course we must wait for Phase III trials results to confirm the benefit of these new treatment strategies toward a new era of chemotherapy-free treatment for follicular lymphoma.

    To investigate the therapeutic effect of oral glucosamine (GS) as an adjunct to hyaluronic acid (HA) injection on patients with temporomandibular joint osteoarthritis (TMJ OA). In this clinical trial, 136 participants, diagnosed as TMJ OA clinically and radiographically, were enrolled and randomized into two groups (Group GS+HA: oral GS+HA injection; Group placebo+HA: oral placebo+HA injection). Pain, maximum inter-incisal mouth opening (MMO), the levels of IL-1β, IL-6, and TGF-β in TMJ synovial were defined as the outcome measurements and conducted before operation, and at 1-month, 1-year follow-up. In both groups, pain scores were decreased and MMOs were increased at 1-month and 1-year follow-up, the changes at 1-year follow-up showed statistically significant intergroup differences. At 1-month follow-up, only IL-6 concentration was lower in group GS+HA than that in group placebo+HA. One year later, TGF-β concentration was higher, IL-6 and IL-1β concentrations were lower in group GS+HA than those in group placebo+HA. Both strategies alleviated symptoms in short term, but the patients treated with GS benefited more than those with placebo in long term, which may be due to the suppression of IL-1β and IL-6 and the stimulation of TGF-β.

    To compare the efficacy and safety of two doses of clotrimazole vaginal tablet 500 mg with two doses of oral fluconazole 150 mg in treating severe vulvovaginal candidiasis (SVVC), 240 consecutive patients with SVVC were studied at the Department of Obstetrics and Gynaecology of Peking University Shenzhen Hospital between June 2014, and September 2015. Patients were randomly assigned in a 1 : 1 ratio to receive treatment with either two doses of clotrimazole vaginal tablet or two doses of oral fluconazole. The clinical cure rates in the clotrimazole group and the fluconazole group at days 7-14 follow-up were 88.7% (102/115) and 89.1% (98/110) respectively; the clinical cure rates at days 30-35 in the two groups were 71.9% (82/114) and 78.0% (85/109) respectively. The mycological cure rates at days 7-14 follow-up in the two groups were 78.3% (90/115) and 73.6% (81/110) respectively. The mycological cure rates of the patients at days 30-35 in the two groups were 54.4% (62/114) and 56.0% (61/109) respectively (P > 0.05). The adverse events of clotrimazole were mainly local. This study demonstrated that two doses of clotrimazole vaginal tablet 500 mg were as effective as two doses of oral fluconazole 150 mg in the treatment of patients with SVVC and could be an appropriate treatment for this disorder.

    DDX3 belongs to DEAD box RNA helicase family and is involved in the progression of several types of cancer. In this work, we employed a High Throughput Virtual screening approach to identify bioactive compounds against DDX3 from ZINC natural database. Ketorolac salt was selected based on its binding free energy less than or equals to -5 Kcal/mol with reference to existing synthetic DDX3 inhibitors and strong hydrogen bond interactions as similar to crystallized DDX3 protein (2I4I). The anti-cancer activity of Ketorolac salt against DDX3 was tested using oral squamous cell carcinoma (OSCC) cell lines. This compound significantly down regulated the expression of DDX3 in human OSCC line (H357) and the half maximal growth inhibitory concentration (IC50) of Ketorolac salt in H357 cell line is 2.6 µM. Ketorolac salt also inhibited the ATP hydrolysis by directly interacting with DDX3. More importantly, we observed decreased number of neoplastic tongue lesions and reduced lesion severity in Ketorolac salt treated groups in a carcinogen induced tongue tumor mouse model. Taken together, our result demonstrates that Ketorolac salt is a newly discovered bioactive compound against DDX3 and this compound can be used as an ideal drug candidate to treat DDX3 associated oral cancer.

    We report an adult T-cell leukemia/lymphoma (ATL) patient whose crusted scabies was successfully treated with oral ivermectin. This 63-year-old man had previously been treated with oral prednisolone, sobuzoxane and etoposide for approximately 1 year. When he developed crusted scabies, he received two doses of oral ivermectin (200 microg/kg) 10 days apart and the concomitant topical application of crotamiton containing 30% benzyl benzoate. This produced remarkable results, suggesting that oral ivermectin should be considered for the treatment of crusted scabies even in immunocompromised patients. While ivermectin may be useful for treating intractable scabies, attention must be paid to the possible appearance of ivermectin-resistant mites.

    Full Text Available Background: Published criteria to distinguish benign colloid nodules from follicular neoplasms emphasize only three interdependent features: size of follicles, amount of colloid, and cellularity. There is a need for the validation of other independent criteria. Methods: This study quantified the significance of cystic change, defined as presence of macrophages, and the presence of hemosiderin in either the macrophages or follicular cells. The cohort consisted of 165 patients with fine needle aspiration (FNA and histologic follow-up of either goiter (101, follicular adenoma (47, or follicular carcinoma (17. Papillary thyroid carcinomas and Hürthle cell neoplasms were excluded from the cohort, because these categories are known to show cystic change and hemosiderin. FNAs were reviewed blindly with the most cellular slide scored for the presence of macrophages and/or hemosiderin. Results: Hemosiderin within macrophages were seen in 67% (68 of 101 of the goiters and only 6% (four of 64 of follicular neoplasms ( P < .0001. All four follicular neoplasms with hemosiderin in macrophages were adenomas. Three of these four had equivocal features of a benign colloid nodule histologically. None of the 17 follicular carcinomas had hemosiderin in macrophages ( P < .12. Macrophages without hemosiderin also strongly distinguished goiters from neoplasms (83% vs 17% but appears less useful as a criterion since macrophages were present within 3 of 17 follicular carcinomas. Hemosiderin within follicular epithelial cells was present in 18% (18 of 101 of goiters, whereas none of the 64 follicular neoplasms had intraepithelial hemosiderin ( P < .0003. Conclusions: If papillary thyroid carcinoma and Hürthle cell neoplasm are ruled out, our findings indicate that the presence of hemosiderin virtually excludes a clinically significant follicular neoplasm.

    Background Less is known about the association between general health-related quality of life (HRQoL) and oral HRQoL (OHRQoL) among patients with specific diseases. The aim of this study was to assess the association between patient-centered outcome measurements (HRQoL and OHRQoL) of oral cancer patients at least 6 months after treatment. Material and Methods HRQoL was measured with the 12-Item Short Form Health Survey (SF-12); OHRQoL was evaluated using the Oral Health Impact Profile (OHIP-14) and the Oral Impacts on Daily Performances (OIDP). Results Higher OHRQoL scores were associated with lower SF-12 domains scores. The OHIP-14 explained 16.5 % of the total variance of SF-12 Physical Component Summary (PCS) and the OIDP explained 16.1 %. In the SF-12 Mental Component Summary (MCS), the total variance explained was 23.9 % by the OHIP-14 and 21.8 % by the OIDP. Conclusions There was a significant association between long-term OHRQoL and HRQoL in oral and oropharyngeal cancer patients. These results may help to carry out new interventions aiming to improve patient´s life overall. Key words:Mouth neoplasms, quality of life, health status, oral health. PMID:26449436

    Full Text Available The cornea is critical for normal vision as it allows allowing light transmission to the retina. The corneal epithelium is renewed by limbal epithelial cells (LEC, which are located in the periphery of the cornea, the limbus. Damage or disease involving LEC may lead to various clinical presentations of limbal stem cell deficiency (LSCD. Both severe pain and blindness may result. Transplantation of cultured autologous oral mucosal epithelial cell sheet (CAOMECS represents the first use of a cultured non-limbal autologous cell type to treat this disease. Among non-limbal cell types, CAOMECS and conjunctival epithelial cells are the only laboratory cultured cell sources that have been explored in humans. Thus far, the expression of p63 is the only predictor of clinical outcome following transplantation to correct LSCD. The optimal culture method and substrate for CAOMECS is not established. The present review focuses on cell culture methods, with particular emphasis on substrates. Most culture protocols for CAOMECS used amniotic membrane as a substrate and included the xenogeneic components fetal bovine serum and murine 3T3 fibroblasts. However, it has been demonstrated that tissue-engineered epithelial cell sheet grafts can be successfully fabricated using temperature-responsive culture surfaces and autologous serum. In the studies using different substrates for culture of CAOMECS, the quantitative expression of p63 was generally poorly reported; thus, more research is warranted with quantification of phenotypic data. Further research is required to develop a culture system for CAOMECS that mimics the natural environment of oral/limbal/corneal epithelial cells without the need for undefined foreign materials such as serum and feeder cells.

    Background The aim is to evaluate periodontal alteration and biochemical markers associated with bone turnover in chronic oral with dicoumarins anticoagulant treatment patients. Material and Methods 80 patients treated with oral anticoagulants were divided into 2 cohort: Group A (n=36) 6 month to 1 year with anticoagulant treatment and Group B (n=44) > 2 years with anticoagulant treatment. Clinical evaluation included: Clinical attachment level (CAL), plaque index (PI) and gingival index (GI). Analytically biochemical parameters of bone remodeling (calcium and phosphorus), formation (total acid phosphatase, alkaline phosphatase and osteocalcin) and resorption (tartrate-resistant acid phosphatase and beta-crosslaps) were evaluated. Results High values of PI (67-100%) especially in men and in Group B were observed. Men with anticoagulation treatment length showed an increased GI (49.167 vs 78.083) while Group B women showed a decreased GI in comparison with Group A (59.389 vs 42.120). Women presented a greater average CAL than men as well as Group B vs Group A but without statistical significance. All biochemical markers were decreased respect to values of general population. Osteocalcin in GroupB women showed a statistically significant outcome vs GroupA (p=0.004). Acid phosphatase (total and tartrate-resistant) has a slight increase in Group B women versus Group A, and Beta-crosslap showed lower values in Group A men than Group B and slightly lower in Group A women versus Group B, without statistical significance. Conclusions Patients showed a slight to moderate degree of periodontal affectation, especially gingivitis related to bacterial plaque. Periodontal disorders tended to be more severe in Group B. While bone remodeling showed an overall decrease with greater affectation of bone neoformation phenomena, bone destruction tended to recover and normalize in time.

    During the last six years we have developed a new CO2 laser technique for the treatment of symptomatic oral cavity hemangioma. Our new technique, named 'laser encircling technique', has especially succeeded during hemangioma buccal maxillary surgeries. The treatment consisted in the application of a line of points of CO2 laser circling the lesion. Depending on the position and size of the lesion, we used from 0.4 to 4.0 Joules/mm2 laser energy density per pulse, causing reduction in the size of the lesion throughout the sclerosis of nutritional vessels which led to reduction in size, volume and color of the hemangiomas with no significant bleeding or inflammatory reaction. In this work forty male and female patients, twelve to fifty years old, presenting medium to small size hemangiomas situated in different sites of the oral cavity such as the tongue, mouth vestibule, pharynx, tonsil area and lips were treated by the procedure described above. The number of laser applications was defined by the peculiarities of each case, varying form 3 to 6 sessions at 4 week intervals, always under local or topic anesthesia. The patients complained about minimal posit operative discomfort and had good cicatrix evolution. The good results achieved by this technique lead to the conclusion that CO2 laser for these types of hemangioma is an efficient and very secure method of treatment. An important aspect of our technique is the fact that using relatively low laser power we do not perform real surgery but a less aggressive alternative of treatment.

    Purpose: No effective agents currently exist to treat oral mucositis (OM) in patients receiving chemoradiation for the treatment of head-and-neck cancer. We identified a novel 21-amino acid peptide derived from antrum mucosal protein-18 that is cytoprotective, mitogenic, and motogenic in tissue culture and animal models of gastrointestinal epithelial cell injury. We examined whether administration of antrum mucosal protein peptide (AMP-p) could protect against and/or speed recovery from OM. Methods and Materials: OM was induced in established hamster models by a single dose of radiation, fractionated radiation, or fractionated radiation together with cisplatin to simulate conventional treatments of head-and-neck cancer. Results: Daily subcutaneous administration of AMP-p reduced the occurrence of ulceration and accelerated mucosal recovery in all three models. A delay in the onset of erythema after irradiation was observed, suggesting that a protective effect exists even before injury to mucosal epithelial cells occurs. To test this hypothesis, the effects of AMP-p on tumor necrosis factor-{alpha}-induced apoptosis were studied in an endothelial cell line (human dermal microvascular endothelial cells) as well as an epithelial cell line (human adult low-calcium, high-temperature keratinocytes; HaCaT) used to model the oral mucosa. AMP-p treatment, either before or after cell monolayers were exposed to tumor necrosis factor-{alpha}, protected against development of apoptosis in both cell types when assessed by annexin V and propidium iodide staining followed by flow cytometry or ligase-mediated polymerase chain reaction. Conclusions: These observations suggest that the ability of AMP-p to attenuate radiation-induced OM could be attributable, at least in part, to its antiapoptotic activity.

    The CD20 marker continues to be exploited as a therapeutic target for non-Hodgkin's lymphoma. Obinutuzumab is part of a new generation of anti-CD20 monoclonal antibodies, which are synthesized using molecular engineering technology, resulting in novel target epitopes and unprecedented optimization of antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis. Rituximab is the current gold standard for anti-CD20 therapy, yet despite outstanding results published over the past decade, many patients continue to relapse after anti-CD20 regimens. Obinutuzumab is slowly positioning itself in the treatment of CD20+ B-cell neoplasms. On the basis of favorable results from the phase III GADOLIN trial, obinutuzumab was recently approved by the U.S. Food and Drug Administration in combination with bendamustine followed by obinutuzumab maintenance, for the treatment of follicular lymphoma (FL) patients who relapsed or are refractory to a rituximab-containing regimen. Additional phase III trials are underway to test obinutuzumab as a first-line anti-CD20 agent in FL with good preliminary results (GALLIUM trial); thus, it is likely that obinutuzumab will soon achieve a first-line indication. It is plausible that obinutuzumab will replace rituximab as the gold standard for chemoimmunotherapy in FL, although some safety concerns still need to be resolved. This review will address the preclinical pharmacology and the main aspects of the clinical development of obinutuzumab for the treatment of FL.

    Abstract Introduction India lists high on patients suffering from diabetes, hypertension, stroke and myocardial infarction. Hence, a large proportion of the population is on long term Oral Antithrombotic Medications (OAM). Though several guidelines exist on dental management of these patients, previous surveys have shown variation among the dentists. Aim The purpose of this study was to assess the knowledge, attitude and practice of dentists in Chennai, India, towards dental management of patients taking OAM using a questionnaire survey. Materials and Methods The survey was conducted among 256 dentists in Chennai, India using a printed questionnaire containing 16 questions, at their university location. Descriptive statistical analysis was used to analyze the data. Results Of the final population of dentists who were included in the survey (n =212), majority of them were aware about drugs such as warfarin and aspirin compared to other newer drugs (dabigatran, rivaroxaban). Most participants took physician’s opinion before proceeding with any invasive dental procedure and thromboembolic events were their major concern while treating patients on OAM. Conclusion The survey revealed dentists are knowledgeable about management of patients on OAM. However, they tend to overestimate the bleeding risk, thus being cautious in their treatment approach. Based on the results of the study, the authors suggest that continuing dental education programs and further training on management of such medically complex patients will be beneficial in order to provide optimum dental care to people taking OAM.

    Limited information is available regarding the use of cyclosporin A (CsA) for the treatment of feline dermatoses. The aim of this retrospective study was therefore to describe the efficacy of CsA for the therapy of eosinophilic granuloma (EG), eosinophilic plaque, indolent ulcer, linear granulomas, idiopathic pruritus and stomatitis. A computer search for feline dermatological cases treated with CsA between 1999 and 2004 was performed. Based on history, clinical signs and laboratory diagnostic tests, it was then possible to divide cases into three groups and to select 23 cats. Seven cats had one or more of the following conditions: EG, eosinophilic plaque, indolent ulcer and/or linear granuloma (group A); eight cats had idiopathic pruritus (group B) and eight cats had plasmacytic stomatitis (group C). Doses ranged from 5.8 to 13.3 mg kg(-1) oral CsA. All cats were monitored, with complete serum blood analysis and physical examination, monthly for a minimum of 6 months. Response to therapy was scored (severity of lesions and pruritus) with a 0-10 visual analogue scale at each visit (day 0, day, 30, day 60, day 90). All cats in groups A and B were cured and were maintained on alternate day therapy. In group C, 4/8 patients went into remission, while remaining cats have a fair to good improvement. Routine haematological and biochemical examination failed to reveal abnormalities related to CsA administration.

    Objective To reconstruct beard with single-follicular-unit grafts in patients with upper lip scar.Methods From May 2001 to May 2005, one-hair follicular units were harvested to treat 20 patients with partial beard loss due to scar formation, 9 out of whom resulting from repair of congenital lip cleft. During the operation, a 1-2mm two-edged sapphire knife was used to make micro-slits. Results A 6-month follow-up revealed that 20 patients recovered quickly and looked natural, with small blood loss and high survival rate, yet 3 with severe scar needed a two-stage operation. Conclusion One-hair follicular unit transplantation is a good option for patients with cicatrical beard loss.

    Full Text Available Follicular mucinosis occurring along with angiolymphoid hyperplasia with eosinophils (ALHE has been described in a 54-year-old female. The patient presented with pruritic erythematous papules on the left frontoparietal scalp. Histopathological examination showed prominent blood vessels in the dermis lined by plump histiocytoid endothelial cells that were surrounded by a dense lymphoid infiltrate with numerous eosinophils; these findings are typical of angiolymphoid hyperplasia with eosinophils. Features of follicular mucinosis were observed in the same section with several hyperplastic follicular infundibula containing pools of mucin in the infundibular epithelium. The concurrent occurrence of these two distinct histopathological patterns in the same biopsy specimen has been described in only three cases to date.

    We investigated cytological changes in oral mucosa smears from patients treated with cryotherapy to determine whether cryotherapy prevented mucositis caused by 5-fluorouracil (5-FU) therapy. Patients with gastrointestinal malignancies were divided into four groups; control patients before 5-FU therapy, patients after 5-FU therapy without cryotherapy, patients with cryotherapy before 5-FU therapy and patients with cryotherapy after 5-FU therapy. Oral mucosa samples from all patients were assessed at the beginning and on day 14 of chemotherapy. We used exfoliative cytology to evaluate cellular changes in the oral mucosa that were caused by 5-FU. Smears from each patient were stained using the Papanicolaou method and analyzed using stereology. Smears were taken from each group before and after 5-FU infusion. We found that nuclear volume was decreased significantly in cells of the 5-FU therapy after cryotherapy patients compared to the 5-FU therapy before cryotherapy patients. We also found significantly decreased cytoplasmic volumes in the 5-FU therapy after cryotherapy patients compared to the 5-FU therapy before cryotherapy patients. The results of cytomorphometric estimations revealed that cryotherapy may be used to prevent damage to oral tissue and may decrease the frequency and duration of oral mucositis caused by 5-FU.

    Verrucous lesions of the oral cavity can be of varied histopathology. The present study evaluates the clinico-pathological features of verrucous lesions of the oral cavity and analyzes the treatment outcomes. This is a retrospective study of 15 consecutive patients who presented with verrucous lesions of the oral cavity, during the 5-year period from January 2006 to December 2010. Demographic, clinico-pathological features, treatment details, and outcomes were analyzed. Fifteen patients with verrucous lesions of the oral cavity were treated with surgery as the primary modality. The mean age was 62.8 years (range 35-85 years). Wide excision of the primary lesion with adequate mucosal and soft-tissue margins was carried out. Free-flap reconstruction was done in eight patients. All patients remain loco-regionally controlled with good functional speech and swallowing outcome. Verrucous lesions of the oral cavity are a distinct clinical entity with varied histopathology. A surgical excision with wide margins and appropriate reconstruction is necessary to optimize the disease and functional outcome.

    Mesenchymal stem cells (MSCs), a subpopulation of adult somatic stem cells, are an attractive stem cell source in regenerative medicine because of their multipotentiality. In this study, the effects of MSCs transplantation on oral ulcer healing were examined. Mesenchymal stem cells were isolated from bone marrow aspirates of dogs by dish adherence and expanded in culture. Oral ulcers were induced by topical application of formocresol in the oral cavity of dogs. Either autologous MSCs or vehicle (saline) was injected around the ulcer. The healing process of the ulcer was monitored clinically and histopathologically. Gene expression of vascular endothelial growth factor (VEGF) was detected in MSCs by reverse transcription-polymerase chain reaction. Expression of VEGF and collagen genes was detected in biopsies from all ulcers. Mesenchymal stem cells expressed mRNA for VEGF MSCs transplantation significantly accelerated oral ulcer healing compared with controls. There was increased expression of both collagen and VEGF genes in MSCs-treated ulcers compared with controls. Mesenchymal stem cells transplantation may help accelerate oral ulcer healing, possibly through the induction of angiogenesis by VEGF together with increased intracellular matrix formation as detected by increased collagen gene expression.

    Full Text Available Introduction. Although follicular thyroid carcinoma is a rare malignant tumor, up to 20% of the patients are threatened by potential complications resulting from infiltrating tumor growth into surrounding tissues. Case report. A 66- year-old female came to hospital with the presence of a growing thyroid nodule of the left lobe. Ultrasonic examination showed a 8 cm hypoechoic nodule in the left lobe. Thyroid scintigraphy showed a cold nodule. CT scan and tracheoscopy showed tracheal infiltration without tracheal obstruction. An extended total thyroidectomy was done, with the left jugular vein, strap muscles and tracheal 2 cm long circular resection. The pathologist confirmed invasive follicular thyroid cancer. After the surgery the patient was treated with radioiodine therapy and permanent TSH suppressive therapy. The patient was followed with measurements of the thyroid hormone and serum thyroglobulin level every six months, as well as the further tests (chest xray, ultrasound of the neck and a whole body scintigraphy were done. After more than three years the patient had no evidence of the recurrent disease. Conclusion. Radical resection of the tracheal infiltrating thyroid cancer with circular tracheal resection and terminoterminal anastomosis followed by radioiodine therapy should be considered the treatment of choice.

    Results: Oral cavity SCC has high chances of local failure when removed inadequately during surgery. Perineural spread, lymphovascular involvement and perinodal spread are important prognostic factors. Conclusions: Most patients of oral cavity cancer present in advanced stages. Close margins and perineural involvement are responsible for local recurrences while perinodal spread and lymphovascular involvement contributes to nodal recurrences. Tobacco consumption is important responsible factor. [Int J Res Med Sci 2016; 4(4.000: 1000-1004

    Acute diarrhoea is one of the main causes of morbidity and mortality among children in low-income countries. Glucose-based oral rehydration solution (ORS) helps replace fluid and prevent further dehydration from acute diarrhoea. Since 2004, the World Health Organization (WHO) has recommended the osmolarity of less than 270 mOsm/L (ORS ≤ 270) versus greater than 310 mOsm/L formulation (ORS ≥ 310). Polymer-based ORS (for example, prepared using rice or wheat) slowly releases glucose and may be superior to glucose-based ORS. To compare polymer-based oral rehydration solution (polymer-based ORS) with glucose-based oral rehydration solution (glucose-based ORS) for treating acute watery diarrhoea. We searched the following sources up to 5 September 2016: the Cochrane Infectious Diseases Group (CIDG) Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 9), MEDLINE (1966 to 5 September 2016), EMBASE (1974 to 5 September 2016), LILACS (1982 to 5 September 2016), and mRCT (2007 to 5 September 2016). We also contacted researchers, organizations, and pharmaceutical companies, and searched reference lists. We included randomized controlled trials (RCTs) of people with acute watery diarrhoea (cholera and non-cholera associated) that compared polymer-based and glucose-based ORS (with identical electrolyte contents). Two review authors independently assessed the search results and risk of bias, and extracted data. In multiple-treatment arms with two or more treatment groups, we combined outcomes as appropriate and compared collectively with the control group. Thirty-five trials that included 4284 participants met the inclusion criteria: 28 trials exclusively included children, five included adults, and two included both adults and children. Polymer-based ORS versus glucose-based ORS (osmolarity ≤ 270) Eight trials (752 participants) evaluated this comparison, and seven trials used rice as a polymer source

    Of 33 infants with hypernatremic dehydration (serum Na+ of greater than or equal to 150 mEq/L) 7 were excluded, 6 because severe alteration of the level of consciousness or shock precluded oral rehydration and 1 because he was given glucose-electrolyte solution plus water. We studied the remaining 27 infants. Twenty (group A) were treated with the World Health Organization-recommended oral rehydration solution (90 mEq/L Na+) and seven (group B) were treated with Pedialyte-RS (Abbott Laboratories Ltd.; 75 mEq/L Na+). The rehydrating solutions were administered in a volume equivalent to twice the clinically estimated fluid deficit. Initial serum sodium was 156.7 +/- 0.9 mEq/L for group A and 155.8 +/- 1.8 mEq/L for group B (mean +/- SEM). The mean time to achieve rehydration was 14.3 and 16.6 h for groups A and B, respectively. Twenty-four hours after commencing oral rehydration, serum Na+ had decreased to 144.8 +/- 1.8 mEq/L for group A and 144.5 +/- 0.9 mEq/L for group B. In two patients in group A, the serum Na+, which, had not decreased to less than 150 mEq/L at 24 h, did so at 48 h. Only in one case (group A) did the serum Na+ increase. This patient had high stool output and failed to become rehydrated after 24 h of unsuccessful oral rehydration. None of the patients had seizures or persistent CNS dysfunction. We conclude that the slow administration of oral rehydration solutions containing either 90 or 75 mEq/L Na+ is a safe and effective treatment of hypernatremic dehydration.

    The aim of this study was to establish an effective mouse model of oral cancer and to use this model to identify potential markers of oral tumor progression. C57BL/6JNarl mice were treated with arecoline, 4-nitroquinoline 1-oxide (4-NQO), or both arecoline and 4-NQO in high and low doses for 8 weeks to induce oral tumor. The induced oral lesions were observed for 20 weeks to assess the efficiency of cancer induction and survival rate of the mice. In addition, two target proteins that are frequently overexpressed during tongue cancer tumorigenesis, alphaB-crystallin and Hsp27, were examined by immunohistochemical analysis. In mice exposed to 4-NQO (200 microg/mL) and arecoline (500 microg/mL), the tongue lesions showed evidence of hyperplasia, papilloma, dysplasia, and carcinoma, and the lesions were pathologically similar to those lesions in human oral cancer. The tongue tumor incidence rate was 100% in mice exposed to concomitant 4-NQO (200 microg/mL) and arecoline (500 microg/mL) treatment, 57% in mice exposed to 4-NQO only, and 0% in mice exposed to arecoline only. Immunohistochemical analysis demonstrated that, consistent with human studies, alphaB-crystallin and Hsp27 were upregulated in murine oral tumors. In conclusion, we have established a powerful animal model that enables the study of the promoting effects of arecoline on tongue tumorigenesis. Data subsequently attained from this mouse model support a role for alphaB-crystallin and Hsp27 as clinical markers for tumor progression.

    Full Text Available A 57-year-old male presented with a 6-month history of blisters and painful erosions on the right buccal mucosa. No skin or other mucosal involvement was seen. The findings of histopathological and direct immunofluorescence examinations were sufficient for the diagnosis of oral mucous membrane pemphigoid in the context of adequate clinical correlation. No response was seen after topical therapies and oral corticosteroids or dapsone. Intravenous immunoglobulin was started and repeated every three weeks. Complete remission was achieved after three cycles and no recurrence was seen after two years of follow-up. The authors report a rare unilateral presentation of oral mucous membrane pemphigoid on the right buccal and hard palate mucosa, without additional involvement during a period of five years. Local trauma or autoimmune factors are possible etiologic factors for this rare disorder, here with unique presentation.

    Desmoid fibromatosis is a fibroblastic neoplasm driven by aberrations within the WNT pathway, exhibiting mutations in β-catenin or APC. We review the long-term follow-up of patients in a phase I study treated with an oral gamma secretase inhibitor, PF-03084014. PF-03084014 was administered orally at doses ranging from 20 to 330 mg twice daily. Tumor assessments were performed using computed tomography/magnetic resonance imaging (CT/MRI) within 4 weeks of study entry, and every other cycle through cycle 9. After cycle 9, patients were evaluated as clinically indicated. Seven patients with desmoid fibromatosis were treated between December 2009 and December 2016 at the University of Colorado. Five patients (71.4%, 95% confidence interval [CI] 29.0-96.3%) achieved a partial response (PR), with a mean time to achieving response of 11.9 months (95% CI 2.5-21.4 months). All patients who achieved a PR continue to maintain responses between 47.9 and 73+ months. Four patients stopped treatment yet remain free of progression between 11 and 53+ months. One patient had PFS of 42+ months, with a 17% decrease in the target lesion. A biopsy performed at the end of the study showed decreased tumoral cellularity compared with previous biopsies. Effective treatment doses ranged from 80 to 330 mg administered orally twice daily. PF-03084014 was effective in treating desmoid tumors, with an objective response rate of 71.4% (95% CI 29.0-96.3%) in this small cohort of patients. PF-03084014 exhibits promising activity, even at relatively low doses (80 mg twice daily), with high tolerability leading to prolonged disease control even after therapy discontinuation.

    Total testosterone is considered to be decreased during the use of combined oral contraceptives. There is, however, considerable concern about the quality of testosterone assays, especially at low levels. We aimed to confirm testosterone levels measured by direct radioimmunoassay in a recent clinical trial with a state-of-the-art LC-MSMS method. Surplus specimens with known testosterone levels collected during the study (Clinical Trial Registration number ISRCTN06414473) were reanalyzed with an LC-MSMS method. This method was compared to another LC-MSMS method that had shown to concur excellently to a reference method. Follow-up experiments were designed to explain the results. In contrast to our expectation, LC-MSMS measurements did not corroborate the data obtained by radioimmunoassay. Subsequent experiments showed that this could be attributed to a strong dependency of the radioimmunoassay on SHBG. Testosterone results (n = 198) obtained by direct radioimmunoassay showed a negative correlation to SHBG levels (r = -0.676; p<0.001). By contrast, testosterone results obtained by LC-MSMS were not related to SHBG (r = 0.100; NS). In conclusion, our results indicate that total testosterone measurements during oral contraceptive use are unreliable when performed with assays sensitive to the SHBG concentration. The discrepancy with the literature can most likely be explained by the sensitivity of the immunoassay used to SHBG. Given the sharp increase in SHBG during the use of many oral contraceptives, total testosterone may not decrease, whereas its bioavailability, estimated by free testosterone levels, will be diminished. Studies aiming at restoration of testosterone homeostasis during oral contraception need to take this into account. Copyright © 2014 Elsevier B.V. All rights reserved.

    (1) Background: Application of nanotechnology or nanomaterials in agricultural food crops has attracted increasing attention with regard to improving crop production, quality, and nutrient utilization. Gold nanoparticles (Au-NPs) have been reported to enhance seed yield, germination rate, and anti-oxidant potential in food crops, raising concerns about their toxicity potential. In this study, we evaluated the oral toxicity of red ginseng exposed to colloidal Au-NPs during cultivation (G-red ginseng) in rats and their intestinal transport mechanism. (2) Methods: 14-day repeated oral administration of G-red ginseng extract to rats was performed, and body weight, hematological, serum biochemical, and histopathological values were analyzed. An in vitro model of human intestinal follicle-associated epithelium (FAE) and an intestinal epithelial monolayer system were used for intestinal transport mechanistic study. (3) Results: No remarkable oral toxicity of G-red ginseng extract in rats was found, and Au-NPs did not accumulate in any organ, although Au-NP transfer to G-red ginseng and some increased saponin levels were confirmed. Au-NPs were transcytozed by microfold (M) cells, but not by a paracellular pathway in the intestinal epithelium. (4) Conclusion: These findings suggest great potential of Au-NPs for agricultural food crops at safe levels. Further study is required to elucidate the functional effects of Au-NPs on ginseng and long-term toxicity. PMID:28335336

    Toxicokinetics of zinc oxide nanoparticles (ZnONP) was studied in rats via a single intravenous (iv) injection and a single oral administration (3 mg/kg or 30 mg/kg), respectively. Blood concentrations of zinc (Zn) were monitored for 7 d and tissue distribution were determined in liver, kidneys, lung, spleen, thymus, brain, and testes. To ascertain the excretion of ZnONP, Zn levels in urine and feces were measured for 7 d. ZnONP were not readily absorbed from the gastrointestinal tract (GIT) after oral administration and were excreted mostly in feces. When the nanoparticles were injected iv to rats at a dose of 30 mg/kg, peak concentration appeared at 5 min but returned to normal range by d 2 (48 h after injection). ZnONP were distributed mainly to liver, kidneys, lung, and spleen, but not to thymus, brain, and testes. The distribution level was significantly decreased to normal by d 7. Feces excretion levels after iv injection supported biliary excretion of ZnONP. In rats injected iv with 30 mg/kg, mitotic figures in hepatocytes were significantly increased and multifocal acute injuries with dark brown pigment were noted in lungs, while no significant damage was observed in rats treated orally with the same dosage.

    Full Text Available Abstract Introduction Lyme neuroborreliosis is the most common bacterial central nervous system infection in the temperate parts of the northern hemisphere. Even though human immunodeficiency virus (HIV -1 infection is common in Lyme borreliosis endemic areas, only five cases of co-infection have previously been published. Four of these cases presented with typical Lyme neuroborreliosis symptoms such as meningoradiculitis and facial palsy, while a fifth case had more severe symptoms of encephalomyelitis. All five were treated with intravenous cephalosporins and clinical outcome was good for all but the fifth case Case presentations We present four patients with concomitant presence of HIV-1 infection and Lyme neuroborreliosis diagnosed in Western Sweden. Patient 1 was a 60-year-old Caucasian man with radicular pain and cognitive impairment. Patient 2 was a 39-year-old Caucasian man with headaches, leg weakness, and pontine infarction. Patient 3 was a 62-year-old Caucasian man with headaches, tremor, vertigo, and normal-pressure hydrocephalus. Patient 4 was a 50-year-old Caucasian man with radicular pain and peripheral facial palsy. Patients one, two, and three all had subnormal levels of CD4 cells, indicating impaired immunity. All patients were treated with oral doxycycline with good clinical outcome and normalization of CSF pleocytosis. Conclusion Given the low HIV-1 prevalence and medium incidence of Lyme neuroborreliosis in Western Sweden where these four cases were diagnosed, co-infection with HIV-1 and Borrelia is probably more common than previously thought. The three patients that were the most immunocompromised suffered from more severe and rather atypical neurological symptoms than are usually described among patients with Lyme neuroborreliosis. It is therefore important for doctors treating HIV patients to consider Lyme neuroborreliosis in a patient presenting with atypical neurological symptoms. All four patients were treated with

    Photodynamic therapy (PDT) is a promising treatment for oral candidoses. Its use as an alternative to antifungals prevents several adverse effects, including microbial resistance. However, most PDT protocols do not employ devices and consumables commonly available in dental practice, thus influencing treatment affordability. This study aimed to determine the efficacy of a PDT method based on light curing units' blue LEDs combined to a plaque-disclosing composition (5% erythrosine) against C. albicans in culture and in a murine model of oral candidosis. Standard and resistant fungal strains were tested in vitro in planktonic and biofilm forms. PDT (pre-irradiation time periods: 30 and 60 s; irradiation time: 3 min) was compared to control conditions without light and/or erythrosine. Mice with induced oral candidosis (n = 40) randomly received PDT or similar control conditions with subsequent C. albicans count. These mice underwent histological analysis, as well as 12 healthy mice submitted to experimental treatments. PDT completely inactivated C. albicans planktonic cells and biofilm. Control conditions presented minor differences (ANOVA, p < 0.05), with mean values ranging from 5.2 to 6.8 log10 (UFC/mL). Infected mice presented no significant difference in C. albicans counts consequent to treatments (ANOVA, p = 0.721), although the PDT protocol was able to enhance the inflammatory infiltrate in healthy mice. It can be concluded that the tested PDT protocol can inactivate C. albicans but still needs further investigation in order to achieve efficacy and safety.

    Miconazole is a synthetic imidazole antifungal that has a broad spectrum of activity against Candida albicans and non-albicans Candida species. The aim of this study was to evaluate the efficacy and safety of miconazole nitrate vaginal suppository and oral fluconazole in treating severe vulvovaginal candidiasis (SVVC). In this prospective, randomized case control study, 577 cases of consecutive patients with SVVC were studied at the Gynecological Clinic of Peking University Shenzhen Hospital from January 1, 2009 through December 31, 2010. Patients with SVVC were treated with two doses of miconazole nitrate vaginal suppository 1,200 mg or two doses of fluconazole 150 mg. The patients were followed up for 7-14 and 30-35 days following the second dose of therapy. The mycological cure rates of the patients on days 7-14 of follow-up were 75.9% (220/290) and 84.0% (241/287) in the miconazole and fluconazole groups, respectively (p 0.05). The study demonstrated that two doses of miconazole nitrate vaginal suppository 1,200 mg were as effective as two doses of an oral fluconazole 150 mg regimen in the treatment of patients with SVVC. © 2015 S.

    We reclassified 720 nonmedullary invasive thyroid carcinomas diagnosed and treated between 1975 and 1993. Twenty-seven cases met the criteria of insular carcinoma and 29 cases those of widely invasive follicular carcinoma. Comparison of these histotypes with respect to pathologic stage and overall, relative, and visceral metastasis-free survival showed a significant association between histotype and pT and pN categories. In particular, pT4 (p AAA transversion at codon 61 of the N-RAS gene in insular carcinoma. These findings suggest that insular carcinoma represents a de novo entity distinct from widely invasive follicular carcinoma, that widely invasive follicular carcinoma has biologic characteristics more consistent with poorly differentiated than well-differentiated carcinomas, and that both insular carcinoma and widely invasive follicular carcinoma share similar molecular alterations.

    To compare the oral health-related quality of life (OHRQoL) between patients with both maxillary and mandibular complete denture and those with either the maxillary or the mandibular complete denture. Satisfaction of denture wearers can be estimated using the OHRQoL questionnaires like the OHIP-EDENT and the Geriatric Oral Health Assessment Index (GOHAI). Two questionnaires were used to compare the OHRQoL between edentulous patients who had conventional removable complete denture on both jaws and those who had on either one of the jaws. The age of the participants ranged from 42 to 75 years, with the mean age of 58 ± 8.12 years. The mean OHIP-EDENT scores were significantly high among those who wore conventional dentures in both jaws (54.12 ± 5.21), compared with the participants who only had denture either on upper or lower jaw (46.52 ± 7.35). It was noticed that the mean GOHAI score was significantly lower (p denture on both upper and lower jaw (28.25 ± 3.67), as compared to those who had conventional denture only on one arch (35.12 ± 2.11). Patients with complete dentures in both jaw (Group I) were less satisfied than patients with single complete denture (Group II). The result obtained in this study shows dissatisfaction with conventional dentures among edentulous patients. © 2012 The Gerodontology Society and John Wiley & Sons A/S.

    Developmental exposure to BPA adversely affects reproductive function. In sheep, prenatal BPA treatment induces reproductive neuroendocrine defects, manifested as LH excess and dampened LH surge and perturbs early ovarian gene expression. In this study we hypothesized that prenatal BPA treatment will also disrupt ovarian follicular dynamics. Pregnant sheep were treated from days 30 to 90 of gestation with 3 different BPA doses (0.05, 0.5, or 5 mg/kg BW/day). All female offspring were estrus synchronized and transrectal ultrasonography was performed daily for 22 days to monitor ovarian follicular and corpora lutea dynamics. Blood samples were collected to assess preovulatory hormonal changes and luteal progesterone dynamics. Statistical analysis revealed that the time interval between the estradiol rise and the preovulatory LH surge was shortened in the BPA-treated females. None of the three BPA doses had an effect on corpora lutea, progestogenic cycles, and mean number or duration of ovulatory and non-ovulatory follicles. However, differences in follicular count trajectories were evident in all three follicular size classes (2–3 mm, 4–5 mm, and ≥ 6 mm) of prenatal BPA-treated animals compared to controls. Number of follicular waves tended also to be more variable in the prenatal BPA-treated groups ranging from 2 to 5 follicular waves per cycle, while this was restricted to 3 to 4 waves in control females. These changes in ovarian follicular dynamics coupled with defects in time interval between estradiol rise and preovulatory LH release are likely to lead to subfertility in prenatal BPA-treated females. - Highlights: • Prenatal BPA shortens interval between estradiol rise and preovulatory LH surge. • Prenatal BPA affects follicular count trajectory and follicular wave occurrence. • Prenatal BPA does not affect ovulatory rate and progesterone dynamics.

    To observe the effect of mefloquine on the tegument of adult Schistosoma japonicum harbored in mice. Twelve mice were each infected with 60-80 S. japonicum cercariae. At 35 days post-infection, 10 mice were treated orally with mefloquine at a single dose of 400 mg/kg. Two mice were sacrificed at 8 h, 24 h, 3 days, 7 days, and 14 days post-treatment respectively, and schistosomes were collected by the perfusion technique, fixed and examined under a scanning electron microscope. Schistosomes obtained from the remaining 2 untreated mice served as control. 8 h post-treatment, male and female schistosomes showed focal swelling of the worm body accompanied by extensive swelling, tough junction and fusion of tegumental ridges. Meanwhile, some of the sensory structures showed enlargement and part of them collapsed. 24 h after mefloquine administration, head portion of some male and female worms revealed high swelling accompanied by severe damage to oral sucker. 3 days post-treatment, focal swelling of worm body along the whole worm was universal. In some male and female worms, the damaged tegument fused together to form a large mass protruding from the tegumental surface. In addition, focal or extensive peeling of tegumental ridges was seen or collapse of enlarged sensory structure resulted in formation of hole-like appearance. 7 days post administration, focal swelling of worm body and damage to tegument induced by mefloquine were similar to those aforementioned, but focal peeling, collapse of enlarged sensory structures, and deformation of oral sucker in male and female worms were universal. 14 days post-treatment, individual male worm survived the treatment revealed normal appearance of tegumental ridges in head portion, although light focal swelling of worm body was still observed. Mefloquine causes focal swelling of worm body, extensive and severe damage to the tegument in adult S. japonicum.

    For 366 patients with polycythaemia vera (PV) or essential thrombocythaemia (ET) diagnosed 1971-1990, oral administration of 32-P was used as myelosuppressive treatment. Retreatment was not restricted to any defined interval and the number of treatments or the total dose were not limited. For 107 patients, follow-up was > 10 years. 15 of these presented with life-threatening occlusive vascular symptoms and their survival was short. For the remaining 92 patients 5-yr survival was not significantly worse than for a Swedish population matched for age and sex. Survival at 10 yr was lower, 51% versus 66% expected. Acute myeloid leukaemia (AML) was diagnosed in 11 of the 107 patients (10.3%). In the whole material of 366 patients, 17 have developed AML with a median time of 8.5 yr from start of treatment. There was a maximum incidence of 4% per yr after 8-12 yr. Later, the incidence decreased. The median annual dose of 32-P for the AML patients was 100 MBq and was not significantly larger than for a matched control group surviving without AML, 95 MBq. The results are compared with reports on PV or ET patients treated with busulphan (Bu) or hydroxyurea (HU). With comparable periods of follow-up there are no indications that an adequate myelosuppression with oral 32-P will be associated with shorter survival or higher incidence of AML than treatment with Bu or HU. It is concluded that, for the time being, oral administration of 32-P is an acceptable standard treatment in PV and ET. (au) (20 refs.).

    Microwave (MW) treatment was used to develop a formulation process for the preparation of wet molded orally disintegrating tablets (ODTs) consisting of mannitol and polymeric disintegrant with improved hardness and disintegration properties. The wet molded tablets were prepared in accordance with the conventional methods and subsequently heated by MW irradiation to induce the swelling of the tablet. Croscarmellose sodium, crospovidone, and low-substituted hydroxypropylcellulose (L-HPC) were evaluated for their use with this technology. NBD-020, which is a grade of L-HPC, provided the better hardness and disintegration results. In addition, the crystalline forms of mannitol impacted on hardness and disintegration properties of the ODT upon MW irradiation. The effects of the disintegrant ratio, δ and β crystalline mannitol ratio, amount of water, and compression force on the ODT properties were evaluated using the design of experiment method. MW-induced swelling was enhanced by an increase in the disintegrant ratio. Although the hardness of the tablet increased following MW treatment, the disintegration time became less than that of the MW-untreated tablets as the β-mannitol ratios increased. Taken together, the results indicated that the polymeric disintegrant greatly improved the properties of the molded tablets in combination with MW treatment. Copyright © 2013 Elsevier B.V.

    Mandibular metastasis of thyroid carcinoma is extremely rare. We present the case of a 46-year-old woman who had bilateral huge cheek masses that had grown rapidly over several years. Intra-oral mucosal tissue biopsy and imaging work-up including computed tomography scan and magnetic resonance imaging were performed and the initial diagnosis was presumed to be central giant cell granuloma. Incidentally detected thyroid lesions were studied with ultra-sonography guided fine needle aspiration and diagnosed as simple benign nodules. Due to continuous oral bleeding and the locally destructive feature of the lesions, we decided to excise the mass surgically. To avoid functional deficit, a stepwise approach was performed: Firstly, the larger left mass was excised and the mandible was reconstructed with a fibular free flap. The final pathologic diagnosis was follicular thyroid cancer. Postoperative I-131 thyroid scan and whole body positron-emissions-tomography were performed. Right side mass was revealed as a thyroid malignancy. Multiple bony metastases were detected. Since further radioactive iodine therapy was required, additional total thyroidectomy and right side mandibulectomy with fibular free flap reconstruction was performed. The patient also underwent high dose radioactive iodine therapy and palliative extra-beam radiotherapy for the metastatic lumbar lesion. Follicular thyroid carcinoma should be considered as a differential diagnosis for mandibular mass lesions.

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors.

    2015-01-01

    Follicular bronchiolitis (FB) also known as hyperplasia of the bronchial associated lymphoid tissue (BALT), or bronchiolar nodular lymphoid hyperplasia, is an entity characterized by the development of lymphoid follicles with germinal centers in the walls of small airways. FB is thought to be caused by antigenic stimulation of BALT, followed by a polyclonal lymphoid hyperplasia. It is currently classified as one of the reactive pulmonary lymphoid disorders in a group known as the lymphoproliferative pulmonary diseases (LPDs). FB is a pathological diagnosis that can be seen in several clinical settings, including connective tissue diseases, immunodeficiency states, autoimmune diseases, infections, obstructive airway diseases, as well as several types of interstitial lung diseases (ILDs). Its characteristics need to be carefully identified and differentiated from other closely related diseases in the group of LPDs due to significant differences in treatment and prognosis.

    2016-10-01

    Despite the improvement in prognosis since the advent of rituximab, follicular lymphoma is still incurable and remains the cause of death of most afflicted patients. With the expanding knowledge of the pathogenesis of B-cell malignancies, in the last few years a plethora of new therapies acting through a variety of mechanisms have shown promising results. This review attempts to analyze the evidence available on these new drugs, which include new monoclonal antibodies and immunoconjugates, the anti-angiogenic and immunomodulatory agent lenalidomide, the proteasome inhibitor bortezomib, inhibitors of B-cell receptor pathway enzymes, such as ibrutinib, idelalisib, duvelisib and entospletinib, BCL2 inhibitors and checkpoint inhibitors. We conclude that despite the high expectations around the new therapeutic options for patients with refractory disease, these new drugs have side effects that require caution with their use, particularly in light of the still short follow up and the lack of both randomized trials and data on combination regimens.

    Single doses (10 mg/kg) of an aqueous solution of (14C)propranolol were administered either orally (po) or intravaginally (ivg) on gestational d 15, or on postpartum d 7-10. Upon ivg administration, (14C)propranolol was quickly transferred to systemic circulation and the mean blood (14C) concentrations were significantly greater during the first 0.25-2 h than in po dosed counterparts. About 98% of the ivg applied dose was absorbed after 6 h in gravid rats, and the combined 6-h excretions of radioactivity in the urine (ivg = 24.6%; po = 22.9%) and feces (ivg = 16.8%; po = 14.6%) were equivalent in both groups. At the end of 6 h, the levels of (14C) in the urinary bladder, adrenal, uterus, ovary, spleen, skeletal muscle, brain, heart, lung and fat were significantly higher in ivg treated rats than po dosed animals. Compared with the maternal plasma (ivg = 0.76; po = 0.88 microgram/ml), the mean concentrations of (14C) in the placentas were similar in both groups, while the amounts of (14C) were three to five times lower in the amniotic fluids and the fetuses of both po and ivg treated dams. In lactating rats, over 99% of the administered radioactivity was absorbed from the vagina within 6 h. The blood concentrations of (14C) were significantly elevated at 0.5 and 1 h in the per vaginam treated animals, and afterward the disappearance rate of (14C) followed a similar course in both groups. Following ivg application, the milk radioactivity peaked at 0.5 h and declined rapidly. However, the appearance of (14C) in milk was rather slow after oral dosing: the milk (14C) peaked between 2 and 3 h posttreatment and remained steady thereafter. The milk to blood (M/B) (14C) concentration ratios were markedly greater during 0.5 to 1 h in the ivg group than in their po dosed counterparts.

    Osteonecrosis of the jaw (ONJ) has been recently described after intravenous administration of amino-bisphosphonates and - less frequently - in association with the use of oral bisphosphonates. Bisphosphonate-Related Osteonecrosis of the Jaw (BRONJ) may affect mandible bone (65%), maxilla bone (26%) and rarely (9%) both sites simultaneously. Although causality may never be proven, emerging experimental data have established a strong association between monthly intravenous bisphosphonate administration and ONJ. Current level of evidence does not fully support a cause and effect relationship between the use of oral BPs and ONJ. In this paper, we report a clinical case of BRONJ in a 73 years old woman affected by rheumatoid arthritis (RA) and periodontitis, after three years of treatment with alendronate 70 mg one a week, plus daily calcium and vitamin D. The patient developed a tooth abscess at the lower jaw, accompanied by increased inflammatory markers, that never returned to normal range despite antibiotic therapy, inducing deterioration of joint synovium. The worsening of joint status after the onset of ONJ was reflected by the progressive increase in the number of swollen (SJ) and tender (TJ) joints, by the deterioration of the score DAS 28 (which passed from 5.46 to 7.07), pain (with VAS increasing from 60 to 90), and by a progressively impaired quality of life, as reported using the HAQ score (from 1,25 to 2,5). The patient was switched to antifracture therapy with strontium ranelate and the osteonecrosis was successfully treated with antibiotics, surgical curettage and local ultrasounds.

    Full Text Available Abstract Background The metabolic syndrome (MetS is a cluster of metabolic abnormalities comprising visceral obesity, dyslipidaemia and insulin resistance (IR. With the onset of IR, the expression of lipoprotein lipase (LPL, a key regulator of lipoprotein metabolism, is reduced. Increased activation of glucocorticoid receptors results in MetS symptoms and is thus speculated to have a role in the pathophysiology of the MetS. Glycyrrhizic acid (GA, the bioactive constituent of licorice roots (Glycyrrhiza glabra inhibits 11β-hydroxysteroid dehydrogenase type 1 that catalyzes the activation of glucocorticoids. Thus, oral administration of GA is postulated to ameliorate the MetS. Results In this study, daily oral administration of 50 mg/kg of GA for one week led to significant increase in LPL expression in the quadriceps femoris (p p > 0.05 of the GA-treated rats compared to the control. Decrease in adipocyte size (p > 0.05 in both the visceral and subcutaneous adipose tissue depots accompanies such selective induction of LPL expression. Consistent improvement in serum lipid parameters was also observed, with decrease in serum free fatty acid, triacylglycerol, total cholesterol and LDL-cholesterol but elevated HDL-cholesterol (p > 0.05. Histological analysis using tissue lipid staining with Oil Red O showed significant decrease in lipid deposition in the abdominal muscle and quadriceps femoris (p p > 0.05. Conclusion Results from this study may imply that GA could counteract the development of visceral obesity and improve dyslipidaemia via selective induction of tissue LPL expression and a positive shift in serum lipid parameters respectively, and retard the development of IR associated with tissue steatosis.

The purpose of the current study was to develop and evaluate a framework aimed at oral healthcare providers to engage in active secondary prevention of eating disorders (i.e. early detection of oral manifestations of disordered eating behaviours, patient approach and communication, patient-specific oral treatment, and referral to care) for patients presenting with signs of disordered eating behaviours. The EAT Framework was developed based on the Brief Motivational Interviewing (B-MI) conceptual framework and comprises three continuous steps: Evaluating, Assessing, and Treating. Using a group-randomized control design, 11 dental hygiene (DH) and seven dental (D) classes from eight institutions were randomized to either the intervention or control conditions. Both groups completed pre- and post-intervention assessments. Hierarchical linear models were conducted to measure the effects of the intervention whilst controlling for baseline levels. Statistically significant improvements from pre- to post-intervention were observed in the Intervention group compared with the Control group on knowledge of eating disorders and oral findings, skills-based knowledge, and self-efficacy (all P oral/systemic health issues. Because the EAT Framework was developed by translating B-MI principles and procedures, the framework can be easily adopted as a non-confrontational method for patient communication.

    The oral ethanol loading test (0.5 g per kg b.m. given as 40% solution) was carried out in 5 groups, each of 10 patients with non-insulin-dependent (type 2) diabetes before and after 10 days of treatment with one of the following sulphonylurea derivatives: tolbutamide 0.5 t.i.d., chlorpropamide 0.5 once daily morning, glibornuride 0.025 t.i.d, glibenclamide 0.005 t.i.d. and glipizide 0.005 t.i.d. The response to alcohol (facial flush, heart rate, blood pressure) were compared, and blood concentration of ethanol, acetaldehyde, pyruvate, lactate, carbonates as well as blood pH, pO2 and pCO2 were determined in fasting state and during 6 hours after alcohol ingestion. In all patients the family history of diabetes and the presence and degree of vascular complications were registered. Evident flushing phenomenon was observed in 6 patients treated with chlorpropamide, in 3 treated with tolbutamide, in 2 treated with glibenclamide, in one receiving glibornuride and in none treated with glipizide. All drugs caused a greater rise of blood ethanol and acetaldehyde levels in relation to the control tests, but the difference reached statistical significance only in the group receiving chlorpropamide. Moreover, patients (pooled) with positive thermographic response had also significantly higher blood levels of ethanol and acetaldehyde during the second test. The ratio of acetaldehyde to ethanol concentration in blood (mumol:mmol) was not significantly changed in any group indicating parallel impairment of both steps of ethanol metabolism. All studied drugs intensified to a similar degree the alcohol-induced hypoglycaemia, but had no significant effect on the decrease of blood pyruvate level neither on the increase of blood lactate level. They didn't change the post-alcohol decrease of blood bicarbonate and pH, and didn't modify the behaviour of partial gas pressure. There was also no difference between pooled groups of patients with positive and negative thermographic reaction

    The safety of enzyme-treated asparagus extract (ETAS) developed as a novel anti-stress functional material was assessed in acute and subchronic studies and genotoxicity assays. In the acute oral dose toxicity study, all rats survived during the test period and ETAS did not influence clinical appearance, body weight gain and necropsy findings at a dosage of 2000mg/kg body weight. Thus, the 50% lethal dose (LD50) of ETAS was determined to be greater than 2000mg/kg. The 90-day subchronic study (500, 1000 and 2000mg/kg body weight, delivered by gavage) in rats reported no significant adverse effects in food consumption, body weight, mortality, urinalysis, hematology, biochemistry, necropsy, organ weight and histopathology. In the micronucleus test of mice, the incidence of micronuclei in ETAS-administered groups (500, 1000 and 2000mg/kg/day, injected twice) was equivalent to that of the negative control group, while the positive control group receiving mitomycin C showed a high incidence. The potential of ETAS to induce gene mutation was tested using four Salmonella typhimurium strains and Escherichia coli WP2uvrA. The test sample was not mutagenic to the test strains. These results support the safety of ETAS as food and dietary supplement.

    Traditionally, preschool-aged children with an acute wheezing episode have been treated with oral corticosteroids (OCSs) based on the efficacy of OCSs in older children and adolescents. However, this practice has been recently challenged based on the results of recent studies. The argument supporting the use of OCSs underscores the observation that many children with recurrent preschool wheezing develop atopic disease in early life which predicts both an increased risk to develop asthma in later life and response to OCS therapy. Further, review of the literature demonstrates heterogeneity of study designs, OCS dosage, interventions, study medication adherence, and settings and overall lack of predefined preschool wheezing phenotypes. The heterogeneity of these studies does not allow a definitive recommendation discouraging OCS use. Advocates against the use of OCSs in this population argue that most of studies investigating the efficacy of OCSs in acute episodic wheeze in preschool-aged children have not demonstrated beneficial effects. Moreover, repeated OCS bursts may be associated with adverse effects. Finally, both sides can agree that there is a significant need to conduct efficacy trials evaluating OCS treatment in preschool-aged children with recurrent wheezing targeted at phenotypes that would be expected to respond to OCSs. This article presents a summary of recent literature regarding the use of OCSs for acute episodic wheezing in preschool-aged children and a "pro" and "con" debate for such use.

    Full Text Available Follicular thyroid adenoma and carcinoma are very common. Benign and malignant lesions are usually indistinguishable from cytology alone and often require confirmatory resection. The spread of follicular carcinoma is usually hematogenous and is treated with surgery and adjuvant radioactive iodine. Very rarely, metastases occur in the mediastinum. Patients usually present with severe compressive symptoms. With proper treatment and follow-up, the prognosis for these type of thyroid malignancies is excellent. In the case presented here, our patient presented to the Universiti Kebangsaan Malaysia Medical Center with a progressively enlarging anterior neck swelling. The swelling had started 10 years before his presentation. We diagnosed him with an advanced thyroid malignancy with bulky mediastinal metastases. After extensive investigations and counseling, we chose to treat the patient with tumor excision and mediastinal metastases resection. Typically, mediastinal resection involves the removal of the sternum and use of an acrylic implant to recreate the sternum. In this case, the sternum and ribs were removed with subsequent myocutaneous flap coverage for the wound defect. Our experience represents an alternative treatment option in cases where implant use is unsuitable.

    Full Text Available OBJECTIVE: To assess the efficacy and safety of oral antidiabetic drugs (OADs in gestational diabetes mellitus (GDM in comparison to insulin. METHODS: A meta-analysis of randomized controlled trials was conducted. The efficacy and safety of OADs in comparison to insulin in GDM patients were explored. Studies were identified by conducting a literature search using the electronic databases of Medline, CENTRAL, CINAHL, LILACS, Scopus and Web of Science in addition to conducting hand search of relevant journals from inception until October 2013. RESULTS: Thirteen studies involving 2,151 patients met the inclusion criteria. These studies were randomized controlled trials of metformin and glyburide in comparison to insulin therapy. Our results indicated a significant increase in the risk for preterm births (RR, 1.51; 95% CI, 1.04-2.19, p = 0.03 with metformin compared to insulin. However, a significant decrease in the risk for gestational hypertension (RR, 0.54; 95% CI, 0.31-0.91, p = 0.02 was found. Postprandial glucose levels also decreased significantly in patients receiving metformin (MD, -2.47 mg/dL; 95% CI, -4.00, -0.94, p = 0.002. There was no significant difference between the two groups for the remaining outcomes. There were significant increases in the risks of macrosomia (RR, 2.34; 95% CI, 1.18-4.63, p = 0.03 and neonatal hypoglycemia (RR, 2.06; 95% CI, 1.27-3.34, p = 0.005 in the glyburide group compared to insulin whereas results for the other analyzed outcomes remained non-significant. CONCLUSION: The available evidence suggests favorable effects of metformin in treating GDM patients. Metformin seems to be an efficacious alternative to insulin and a better choice than glyburide especially those with mild form of disease.

    Faced with rising healthcare costs, state Medicaid programs need short-term, easily calculated budgetary estimates for new drugs, accounting for medical cost offsets due to clinical advantages. To estimate the budgetary impact of direct-acting oral anticoagulants (DOACs) compared with warfarin, an older, lower-cost vitamin K antagonist, on 12-month Medicaid expenditures for nonvalvular atrial fibrillation (NVAF) using number needed to treat (NNT). Medicaid utilization files, 2009 through second quarter 2015, were used to estimate OAC cost accounting for generic/brand statutory minimum (13/23%) and assumed maximum (13/50%) manufacturer rebates. NNTs were calculated from clinical trial reports to estimate avoided medical events for a hypothetical population of 500,000 enrollees (approximate NVAF prevalence × Medicaid enrollment) under two DOAC market share scenarios: 2015 actual and 50% increase. Medical service costs were based on published sources. Costs were inflation-adjusted (2015 US$). From 2009-2015, OAC reimbursement per claim increased by 173 and 279% under maximum and minimum rebate scenarios, respectively, while DOAC market share increased from 0 to 21%. Compared with a warfarin-only counterfactual, counts of ischemic strokes, intracranial hemorrhages, and systemic embolisms declined by 36, 280, and 111, respectively; counts of gastrointestinal hemorrhages increased by 794. Avoided events and reduced monitoring, respectively, offset 3-5% and 15-24% of increased drug cost. Net of offsets, DOAC-related cost increases were US$258-US$464 per patient per year (PPPY) in 2015 and US$309-US$579 PPPY after market share increase. Avoided medical events offset a small portion of DOAC-related drug cost increase. NNT-based calculations provide a transparent source of budgetary-impact information for new medications.

    Oral mucositis caused by cancer chemotherapy can result in significant clinical complications. There is a strategic need to accelerate the delineation of the pathobiology. This proof-of-principle study was designed to demonstrate the feasibility of studying archived oral mucosal specimens to further delineate oral mucositis pathobiology. Twenty-nine formalin-fixed and paraffin-embedded tissue blocks of 25-year-old oral mucosa autopsy specimens from cancer chemotherapy patients were studied. Standardized technology was utilized, including RNA isolation and amplification, array hybridization, and gene expression analysis. A predominance of DNA damage in buccal mucosal basal keratinocytes was observed. Data comparing basal cells from buccal vs. gingival mucosa identified differential gene expression of host responses in relation to pathways relevant to oral mucositis pathogenesis, including responses to cancer-associated inflammation. This proof-of-principle study demonstrated that archived oral mucosal specimens may be a potentially valuable resource for the study of oral mucositis in cancer patients.

    We report a case of possible retroperitoneal metastasis of breast cancer successfully treated with oral S-1 and cyclophosphamide therapy after docetaxel and cyclophosphamide (TC) therapy. A 57-year-old woman with a history of bilateral breast cancer showed an increase in tumor markers during treatment with oral anastrozole as postoperative adjuvant therapy 4 years after her second cancer surgery. After careful examination, the patient was diagnosed as having multiple bone metastases and her medication was changed to oral letrozole. After 3 months, the patient developed left back pain and was referred to our hospital. CT scanning showed an enhanced mass in the region from the left perirenal and posterior pararenal spaces to the left psoas major muscle and the anterior aspect of the left iliacus muscle, suggesting retroperitoneal metastasis. TC therapy was performed and, as a result, tumor markers decreased and the mass disappeared on CT imaging. After discontinuation of TC therapy, the tumor markers increased again, following which oral S-1 and cyclophosphamide therapy were administered, and the tumor markers decreased. At the time of this writing, the patient is still undergoing therapy, and no recurrence has been observed. We concluded that oral S-1 and cyclophosphamide therapy were useful in the present case and were associated with few adverse effects.

    To observe the effect of Shenlong Oral Liquid(SLOL)combined with radiotherapy in treating nasopharyngeal carcinoma (NPC). Methods: Effects of the combined therapy, including clinical effects, changes of cellular immunity and side effects, in treating 60 NPC patients (in the treated group) were observed and compared with those of the other 60 patients treated with radiotherapy alone (in the control group). Results: (1)The side effects of radiation in the treated group were lower than those in the control group significantly (P<0.05). (2) The short-term remission rate of nasopharyngeal and neck metastatic tumor in the two groups was not significantly different (P>0.05). (3) The dose for complete remission of nasopharyngeal and neck tumor in the treated group was lower than that in the control group (P<0.01). (4) No change of T-lymphocyte subsets was found in the treated group after treatment, but in the control group , OKT3,OKT4,and OKT4/OKT8 ratio were markedly decreased (P<0.05). (5) The survival rate in the treated group was higher than that in the control group, but with no statistical significance (P=0.0518). Conclusion: The combined therapy of NPC with SLOL and radiotherapy is able to reduce side-effect of radiotherapy, improve the cellular immunity, reduce the dose of radiation for tumor remission and enhance the therapeutic effect of radiotherapy. It showed a trend of raising the long-term survival rate of NPC patients.

    2011-08-01

    Full Text Available Structural and morphometric features of thyroid C and follicular cells were studied in adult rat females after treatment with synthetic salmon calcitonin (CT. The animals were chronically treated with either a low (10 IU/kg b.w or a high (100 IU/kg b.w dose of CT. A stereological method was applied to determine the volume density and the number of immunoreactive C cells. The height and volume density of follicular epithelium, colloid, interstitium and the follicles (epithelium plus colloid, as well as the index of activation rate were calculated. A significant decrease in body weight, as well as the volume density of immunoreactive C cells and the number of C cells per mm2, was observed in rats treated with both doses of CT. The height and volume density of follicular epithelium and follicles, as well as the index of activation rate were significantly increased in the animals given the high CT dose, while the volume densities of colloid and interstitium were reduced. No significant changes in the examined morphometric parameters were detected after treatment with the low CT dose. According to these results it can be concluded that the structural features of thyroid C and follicular cells were affected by the high dose CT treatment in the opposite manner, while the low dose CT treatment influenced only C cells.

  20. Effects of microsomal enzyme inducers on thyroid follicular cell proliferation and thyroid hormone metabolism.

    Klaassen, C D; Hood, A M

    2001-01-01

    The effects of microsomal enzyme inducers on thyroid hormone homeostasis and the thyroid gland are of concern. We have investigated the effects of microsomal enzyme inducers on thyroid follicular cell proliferation and thyroid hormone metabolism in rats. We have shown that small increases in serum TSH can result in large increases in thyroid follicular cell proliferation. Furthermore, only those microsomal enzyme inducers that increase serum TSH--that is, phenobarbital (PB) and pregnenolone-16alpha-carbonitrile (PCN)-increase thyroid follicular cell proliferation, whereas those microsomal enzyme inducers that do not increase serum TSH--that is, 3-methylcholanthrene (3MC) and Aroclor 1254 (PCB)-do not increase thyroid follicular cell proliferation. Deiodination does not appear to be the reason why serum T3 concentrations are maintained in microsomal enzyme inducer-treated rats. We have also shown that those microsomal enzyme inducers that increase serum TSH increase T3 UDP-glucuronosyltransferase (UGT) activity, whereas those microsomal enzyme inducers that do not increase serum TSH do not increase T3 UGT activity. This finding suggests that induction of T3 glucuronidation, rather than T4 glucuronidation, mediates increases in serum TSH of microsomal enzyme inducer treated rats.

    A case of metastasis to the sella turcica from a follicular adenocarcinoma of the thyroid gland is presented. Metastasis to this site is rare and review of the literature reveals only 12 cases of metastatic thyroid carcinoma involving the sella turcica and pituitary gland. The optimal treatment strategy is still to be determined. A 43-year-old woman presented with headache, nausea, visual impairment and galactorrhea. An MRI scan of the cranium revealed an enhancing destructive sellar lesion. The patient underwent transsphenoidal removal of the lesion to alleviate visual loss. The histological features of the sellar tumor were identical to those of a follicular adenocarcinoma partially removed from the thyroid gland 22 months earlier. Total thyroidectomy followed by three courses of iodine-131 ablation enhanced with synthetic thyrotropin and thyroid hormone suppression therapy was instituted. The post-operative course was satisfactory with improved vision and ceased galactorrhea. This case was successfully treated with a combination of surgical removal, iodine-131 ablation and hormone suppression therapy, which resulted in disease control duration of four years. Sella turcica metastases of thyroid carcinoma are exceedingly rare and currently there are no established therapeutic guidelines.

    Full Text Available Follicular cell-derived well-differentiated thyroid cancer, papillary (PTC and follicular thyroid carcinomas (FTC compose 95% of all thyroid malignancies. Familial follicular cell-derived well-differentiated thyroid cancers contribute to 5% of those cases. These familial follicular cell derived carcinomas or non-medullary thyroid carcinomas (NMTC divide into two clinical-pathological groups. One group, syndromic-associated, composed by predominately non-thyroidal tumors, is comprised of Pendred syndrome, Warner syndrome, Carney complex type 1, PTEN-hamartoma tumor syndrome (Cowden disease; PHTS, familial adenomatous polyposis (FAP/Gardner syndrome. Additionally other less established links correlated to the development of follicular cell-derived tumors have also included Ataxia-teleangiectasia syndrome, McCune Albright syndrome, and Peutz-Jeghers syndrome. The subsequent group encompasses syndromes typified by non-medullary thyroid carcinomas or NMTC, as well as, pure familial (f PTC with or without oxyphilia, fPTC with multinodular goiter and fPTC with papillary renal cell carcinoma. This heterogeneous group of diseases has not a established genotype-phenotype correlation as the well-known genetic events identified in the familial C-cell-derived tumors or medullary thyroid carcinomas (MTC. Clinicians should be have the knowledge to identify the likelihood of a patient presenting with thyroid cancer having an additional underlying familial syndrome stemming from characteristics through morphological findings that would alert the pathologist to have the patient undergo subsequent molecular genetics evaluations. This review will discuss the clinical and pathological findings of the patients with familial papillary thyroid carcinoma, such as familial adenomatous polyposis, Carney complex, Werner syndrome, and Pendred syndrome and the heterogeneous group of familial papillary thyroid carcinoma.

To screen antifugal agents from Chinese traditional and herbal drugs by NCCLS M27-A2 method. Using YBC Test Kit to identify 20 clinical oral Candida isolated from head and neck cancer patients treated with radiotherapy or chemotherapy. The in vitro susceptibilities of 20 oral Candida spp. to 5-flucytosine (5-FC), itraconazole (ITR), fluconazole (FLU), the extracts of 6 Chinese traditional and herbal drugs (caltrop, honeysuckle flower, dandelion, green tea, pine bark, red trefoil) and utility componets of 7 Chinese traditional and herbal drugs (sophorcarpidine, aloperine, archin, glycyrrhizic acid, glycosides of white peony root, glycosides of baikal skullcap root, hydrochloric berberine) were determined by NCCLS M27-A2 method. The proportion of no-C. albicans in all Candida spp. were 25%. All strains were sensitive to 5-flucytosine, 25% stains were resistant to fluconazole and 40% stains were resistant to itraconazole. In all agents from Chinese traditional and herbal drugs, glycosides of white peony root and hydrochloric berberine (C20H18CINO4) exhibited antifungal activity, especially to C. glabrates. The proportion of no-C. albicans in all oral Candida spp. isolated from head and neck cancer patients treated with radiotherapy or chemotherapy was pretty high. NCCLS M27-A2 micro-dilution method is a reliable and reproducible method and can be used to screen antifugal agents from Chinese traditional and herbal drugs.

    Full Text Available Orthodontic appliances modify the local environment of the oral cavity, increase the accumulation of dental plaque, and affect the condition of the gingiva. The aim of this study is assessment of Brazilian propolis toothpaste’s effect on plaque index (PLI and gingival index (GI in patients with CL/CLP treated using orthodontic appliances in the 35-day study period. The study population included 96 patients of an Orthodontic Outpatient Clinic, ACSiMS in Bytom. All the patients participated in the active phase of orthodontic treatment using buccal multibracket appliances or removable appliances. During the first examination, each patient was randomly qualified to the propolis group or control group. A statistically significant decrease in GI and PLI in the entire propolis group (P<0.01 was shown during repeated examination. Insignificant change in GI was in the entire control group during the repeated examination compared to the baseline. Similar result was obtained in patients treated with multibracket and removable appliances. The orthodontic appliance type did not affect the final dental plaque amount and gingival condition in patients using the propolis toothpaste. These results may be clinically useful to improve prevention and control oral infectious diseases during orthodontic treatment patients with oral cleft.

    Patients with oral cancer can develop restricted mouth opening (trismus) because of the oncologic treatment. Maximum mouth opening (MMO) was measured in 143 patients shortly before treatment and 0, 6, and 12 months posttreatment, and the results were analyzed using a linear mixed-effects model. In every patient, MMO decreased after treatment. The patients who underwent surgery, recovered partially by 6 and 12 months after treatment, whereas the patients who received both surgery and radiotherapy or primary radiotherapy did not recover. Tumor location, tumor size, and alcohol consumption had independent effects on MMO. Having trismus (MMO trismus after oral cancer treatment. © 2014 Wiley Periodicals, Inc.

    The main products in the ozonolysis of unsaturated triglycerides or vegetable oils are peroxides, aldehydes, Criegee ozonides and carboxylic acids. Some of these compounds are present in different concentrations in the biological fluids. The aim of this work is to study, using gas chromatography-mass spectrometry (GC-MS), the organic acid excretion in urine of rats orally treated with ozonized sunflower oil (OSO), ozonized triolein or ozonized trilinolein. Oral administration of OSO to Wistar rats has produced changes in the urinary content of dicarboxylic organic acids. Among others heptanedioic (pimelic acid) and nonanedioic acids (azelaic acid) were the major increased dicarboxylic acids found. The urinary dicarboxylic acid profiles of rats which received ozonized triolein only showed an increase in heptanedioic and nonanedioic acids. However, when ozonized trilinolein is applied, the profile is similar to that obtained when OSO is administered. A biochemical mechanism is proposed to explain the formation of dicarboxylic acids from ozonated unsaturated triglycerides.

Few studies have assessed the effect of palatal expanders on OHRQoL. The aim of this study was to evaluate the impact of palatal expanders on OHRQoL and to compare it with that of fixed orthodontic appliances. Materials and methods: All adolescent and adult orthodontic patients who were undergoing treatment with fixed appliances or palatal expanders between July 2015 and January 2016 in King Abdulaziz University Orthodontc Dental Clinics, were recruited (n=399. The OHRQoL of each participant was assessed using the shortened Arabic version of the Oral Health Impact Profile-14 questionnaire. OHRQoL was compared between users of fixed appliances and users of palatal expanders; it was also compared after stratifying the patients by gender. Chi-squared and Fisher’s exact tests were used, as indicated. Results: Palatal expanders had significantly greater negative effects on chewing ability (P≤0.01 and pronunciation (P=0.048. However, fixed orthodontic appliances had significantly greater negative impacts on mouth aching (P=0.003, difficulty in relaxing (P=0.01, irritability (P=0.001, and embarrassment (P≤0.01. Conclusion: Palatal expanders had a significantly greater negative impact on some aspects of OHRQoL when compared with fixed orthodontic appliances in adolescents and young adults.

    Full Text Available Mesenteric panniculitis (MP is a rare disease occasionally complicated with lymphoma. A 55-year old female presented with MP accompanied by malignant lymphoma. This patient was first treated for follicular lymphoma and subsequently for panniculitis. After 6 courses of R-CHOP chemotherapy, the treatment response was partial. An additional course of salvage chemotherapy led to a complete response. Since the mesenteric mass progressed simultaneously with the regression of other lymphoma lesions, we performed a biopsy of the mesenteric mass and pathologically confirmed an MP lesion without lymphoma. Subsequent high-dose chemotherapy led to CR and the MP lesion remained stable. In the present case, MP progressed with chemotherapy. We concluded that mesenteric lesions suspected of progressing or recurring should be diagnosed pathologically even if asymptomatic.

    Introduction: Oral Verrucous Carcinoma (OVC) is described apart of the Squamous Cell Carcinoma (SCC) due to its specific properties. The objective of our study is to show our series of cases of OVC and to compare with the SCC in terms of clinical manifestations, epidemiology, histopathology, treatment and follow-up. Material and Methods: This is a retrospective study of all the OVC treated in our department between January-2007 and December-2011. The analyzed variables were sex, age, localization in the oral cavity, histopathology, number of biopsies needed to diagnose OVC, TNM classification, treatment and recurrences during follow-up. Results: Our sample was composed by n=14 patients, 57% female, with a mean age of 69.14 years. The most common localization was buccal mucosa (n=5). Seven patients were diagnosed of OVC with the first biopsy. TNM classification was: pT1: 7 patients, pT2: 3 patients, pT3: 3 patients, pT4: 1 patient. No cervical metastases were observed either in cervical neck dissection or during the follow-up of the patients. The treatment was surgery with clinical resection margins up to 1 cm in all cases, followed by radiotherapy in selected cases. Only n=1 patient (7.69%) presented a recurrence after 34 months of follow-up. The overall survival rate was 92.85%. Conclusions: In our population, OVC represents the 6.16% of all oral cavity and oropharynx cancer, and is more frequent in female patients above 70 years old. It uses to rise over a previous lesion, and usually affects the buccal mucosa. In patients with high suspicious lesions, more than one biopsy may be needed to diagnose OVC. No patient showed cervical dissemination. In our experience, treatment based on local resection, without cervical neck dissection, could be a good option for these patients.

    Tongue strength is reduced in patients treated with chemoradiotherapy for oral/oropharyngeal cancer. Tongue strengthening protocols have resulted in improved lingual strength and swallowing in healthy individuals, as well as in patients following a neurological event. However, no studies have examined the efficacy of tongue strengthening exercises on tongue strength, swallowing, and quality of life (QOL; Head and Neck Cancer Inventory) in patients treated with chemoradiotherapy. A randomized clinical trial examined the effects of a tongue strengthening programme paired with traditional exercises vs. traditional exercises alone. Dependent variables included tongue strength, swallowing, and QOL in a group of patients with oral and oropharyngeal cancer treated with primary radiotherapy with or without chemotherapy. Differences with regard to tongue strength and oropharyngeal swallow efficiency (OPSE) were not observed within or between groups. QOL in the eating and speech domains improved following treatment in both groups. However, the experimental group demonstrated greater impairment in QOL in the social disruption domain following treatment, whereas the control group demonstrated a slight improvement in functioning. Tongue strengthening did not yield a statistically significant improvement in either tongue strength or swallowing measures in this patient cohort. Patient compliance and treatment timing may be factors underlying these outcomes.

    Non-Hodgkin Lymphomas (NHL) represent a recent and fascinating domain of hemato-oncology, in which remarkable progress has been made. The conventional treatments of indolent lymphomas do not extend the survival rate, nor do they cure. Recent directions are centered on using several new drugs that are capable of overcoming the mechanisms that are resistant to recovery. The initiation of immunotherapy (Rituximab in 1997) seems to have changed the natural evolution of follicular lymphomas (FL). It is possible that resistance to healing in follicular lymphomas may be neutralized with Rituximab by suppressing STAT-1 positive macrophages that are present in the cellular microenvironment.Thereinafter, the re-evaluation of recent models of prognostic and therapeutic paradigmas that were used in FL became compulsory.The purpose of the paper is to compare the evolution of patients with follicular lymphoma and the period of response, according to the treatments. The study group consisted of the 71 patients diagnosed with follicular lymphoma, out of a total of 767 malignant lymphatic proliferations with B cells, for a period of 7 years (2002-2008), at the Hematology Department, Hospital Coltea, Bucharest and Hematology Department, Universitary Hospital, BucharestResults and conclusions: Combining chemotherapy with Rituximab had better results compared to the same chemotherapy, administered alone, both in induction and in case of relapse. The overall response rate in our study group was 74.7%, out of which 42.3% complete remissions. The overall response rate was 84.61% in the Rituximab group, compared to 68.88% in patients without Rituximab.

    Follicular bronchiolitis (FB) is a benign progressive lung disease. It is characterized with lymphoplasmocellular infiltration and hyperplastic follicles in the peribronchial areas in the small airways. Follicular bronchiolitis should be considered in cases where chronic cough, recurrent upper respiratory tract infections and progressive dyspnea are observed in children. The diagnosis should be supported by lung biopsy. A 8-year old female patient presented to our hospital with complaints including continuing cough and wheezing. Bilateral extensive rales and rhonchi in the lungs were heard on auscultation and lung graphy revealed reticuloglandular appearance. Bilateral extensive septal thickennings, reticulonodular appearance, patchy bronchiectasis, bronchiolectasis and peribronchial thickennings were found on high-resolution thoracal computarized tomography. A diagnosis of follicular bronchiolitis was made as a result of lung biopsy. Improvement was observed in the complaints and findings of our patient after methylprednisolone treatment. This patient was presented to emphasize rare interstitial lung diseases should also be considered in children who present with a clinical picture of chronic bronchial obstruction and do not respond to standard treatment.

    Follicular carcinomas are the second most common form of thyroid cancer, accounting for 10 to 20% of all thyroid cancers. Follicular carcinomas have a propensity to metastasize via the bloodstream, spreading to bone, lungs, liver, and elsewhere. We described the case of a 48-year-old woman who presented with swelling of the left pre auricular area, which was a consequence of a metastatic follicular carcinoma of the masticator space. Plain films showed ill defined erosive bony changes from the left condylar head to the mandibular notch. Contrast-enhanced CT images showed a well circumscribed round mass with well enhancement within left masticator space. On MR images, the mass was heterogenously hyperintense to the muscle on T2-weighted images and isointense or hyperintense to the muscle on T1-weighted images, and showed good enhancement on contrast-enhanced T1-weighted images. Upon microscopic examination, the metastatic mass was found to be composed of fairly uniform cells forming small follicles containing colloid, showing capsular and vascular invasion.

    The cytological morphology observed in liquid-based cytology (LBC) preparations is dissimilar to that of conventional preparations. The aim of this report is to clarify the cytological differences between benign follicular nodules (BFNs) and follicular neoplasms (FNs) in LBC preparations and identify novel diagnostic criteria for LBC preparations. A retrospective review of LBC preparations from 38 BFN and 74 FN (57 follicular adenomas and 17 follicular carcinomas) cases confirmed by histological examination was conducted. LBC samples were obtained from the washout fluid in aspiration needles, fixed with CytoRich-RED(TM) , and prepared using the SurePath(TM) method. Fibrin was observed in 43.2% of FNs and in 23.7% of BFNs. The incidences of intercellular spaces, distinct outer margin, and cytoplasmic process were significantly higher in BFNs (P < 0.01, P < 0.01, and P < 0.05, respectively). Elongated microfollicles were seen in 55.4% of FNs and 10.5% of BFNs (P < 0.01). Membranous materials encircling the outer edge of the follicles were observed only in BFN cases (5.8%). There were no significant differences between follicular adenoma and carcinoma. Intercellular spaces, distinct outer margins of the follicular clusters, cytoplasmic process, and membranous materials constitute indicators of BFN in LBC preparations. Fibrin and elongated microfollicles point to FN. We believe that these findings will improve the diagnostic accuracy of thyroid LBC preparations. Diagn.

    Two experiments were conducted to examine circulating concentrations of progesterone (P4) in cows with ovarian follicular cysts (OFCs) and to relate differing levels of P4 to subsequent follicular events. In experiment 1, peripheral concentrations of P4 were determined in cows diagnosed with OFCs. Nonpregnant, lactating Holstein and Jersey cows (n = 32) were diagnosed as having OFCs by rectal palpation. Ovarian follicular cysts were then examined by transrectal ultrasonography to confirm the presence of OFCs (follicle diameter, >/=17 mm; absence of luteal tissue). At confirmation, a blood sample was collected for quantification of P4. The concentration of P4 at confirmation was classified as low (/=10 mm) that formed in the presence of an OFC was determined and related to circulating concentrations of P4 during follicular development. Follicles (n = 59) that formed in the presence of an OFC ovulated (n = 19), formed a cyst (n = 30), or underwent normal growth and regression (NGR; n = 10). Endogenous P4 in the 7-day period during follicular development was classified as low (if P4 dropped to day or longer), intermediate (if P4 averaged between 0.1 and 1.0 ng/ml and never dropped to 1.0 ng/ml and never dropped to <0.1 ng/ml). In the presence of intermediate P4, 75% of observed follicles formed cysts, compared with 10% that ovulated and 15% that experienced NGR. In the presence of low P4, 53%, 41%, and 6% of follicles ovulated, formed a follicular cyst, or experienced NGR, respectively. Thus, an association between intermediate P4 and the formation of OFCs was established.

    The impairment of the appearance is a major problem for patients with carcinomas of the oral cavity. These patients want to recover their preoperative facial appearance. Some do not realize that this is not always possible and hence develop a desire for further cosmetic and reconstructive surgery (CRS) which often causes psychological problems. The desire of patients for CRS (N = 410; 26%) has been acquired in this DÖSAK rehab study including multiple reasons such as medical, functional, aesthetic and psychosocial aspects. They relate to the parameters of diagnosis, treatment and postoperative rehabilitation. Patients without the wish for CRS (N = 1155; 74%) served as control group. For the surgeons, knowledge of the patient's views is relevant in the wish for CRS. Nevertheless, it has hardly been investigated for patients postoperatively to complete resection of oral cancer. In this retrospective cross-sectional study, questionnaires with 147 variables were completed during control appointments. Thirty-eight departments of Oral and Maxillofacial Surgery took part, and 1652 German patients at least 6 months after complete cancer resection answered the questions. Additionally, a physician's questionnaire (N = 1489) was available. Statistical analysis was performed with SPSS vers. 22. The patient's assessment of their appearance and scarring are the most important criteria resulting in wishes for CRS. Furthermore, functional limitations such as eating/swallowing, pain of the facial muscles, numb regions in the operating field, dealing with the social environment, return to work, tumour size and location, removal and reconstruction are closely related. The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it has to be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients' needs and is able to compare them with the

    A man underwent total thyroidectomy for goiter when he was 62 years old. The pathology report informed on a 5.5 cm oncocytic follicular adenoma and a 3.5 mm papillary microcarcinoma. Due to the papillary tumor, he was treated with ablative radioiodine therapy and suppressive doses of levothyroxine. After uneventful follow-up for 9 years, increased levels of serum thyroglobulin were detected. Further imaging studies including a whole body scan (WBS) after an empirical dose of 200 mCi 131I were negative. Two years later, a 99mTc SestaMIBI WBS and a 2-[18F]-fluoro-2-deoxy-d-glucose positron-emission tomography showed a well-delimited focal uptake in the right femur. A bone biopsy of the lesion demonstrated metastasis of follicular thyroid carcinoma. Retrospective histological reexamination of available material from the primary oncocytic thyroid tumor failed to reveal definitive traits of malignancy. Learning points Oncocytic follicular thyroid tumors are a relatively uncommon variant of follicular thyroid neoplasms mostly composed of distinctive large oxyphilic cells (Hürthle cells).Criteria for the distinction between benign and malignant oncocytic neoplasms are not different from those used in the diagnosis of ordinary follicular tumors.Some cases of apparently benign oncocytic neoplasms have been found to develop malignant behavior.Search to rule out vascular and capsular invasion should be particularly exhaustive in histological assessment of oncocytic thyroid tumors.Even so, long-term surveillance remains appropriate for patients with large apparently benign oncocytic tumors.

    Indirect evidence in the nonhuman primate and human suggests that angiogenesis and regulators of angiogenesis such as vascular endothelial growth factor (VEGF) may play an active role in cyclic folliculogenesis. Indeed, the follicle selected for maturation and ovulation possesses a denser microvascular network, and VEGF messenger ribonucleic acid and its protein have been identified in granulosa cells of the developing follicle during the mid- and late follicular phases, with a more intense signal in the mature follicle. The objective of this study was to obtain direct evidence in the nonhuman primate for an active role of VEGF in follicular growth and maturation by studying the effect of VEGF-blocking antibodies in this process. After documenting two normal ovulatory cycles, female rhesus monkeys (n = 7) received iv injections of anti-VEGF antibodies (0.5 mg) twice on successive days in the late follicular phase. Three monkeys also received nonspecific goat IgG (0.5 mg) twice on successive days in the late follicular phase. Daily measurements of estradiol, progesterone, LH, and FSH were obtained during the two control cycles, the anti-VEGF treatment and posttreatment cycles, and the IgG treatment cycle. Anti-VEGF antibody administration significantly lengthened the follicular phase in six of seven monkeys to 17.8 +/- 1.7 vs. 10.0 +/- 0.7 and 9.8 +/- 0.6 in control cycles and 10.7 +/- 0.3 days (mean +/- SE) in IgG-treated cycles. The expected late follicular phase rise in estradiol, as documented in the control cycles (day 0, 96.1 +/- 6.0; day 1, 125.5 +/- 20.0; day 2, 165.5 +/- 24.9; day 3, 183.8 +/- 11.0 pg/mL), was interrupted by anti-VEGF antibody treatment (99.3 +/- 5.0, day 0, preinjection control) to 63.3 +/- 12.2 (day 1), 48.5 +/- 8.7 (day 2), and 57.6 +/- 9.0 (day 3). Mean FSH levels were significantly increased by day 2 of anti-VEGF antibody treatment. After a variable delay, estradiol concentrations increased to reach a preovulatory peak in all anti-VEGF-treated

    (Trans)-3,7-Dimethyl-2,6-octadien-1-ol, commonly called geraniol (Ge-OH), is an acyclic monoterpene alcohol with well-known anti-inflammatory, antitumoral, and antimicrobial properties. It is widely used as a preservative in the food industry and as an antimicrobial agent in animal farming. The present study investigated the role of Ge-OH as an anti-inflammatory and anti-dysbiotic agent in the dextran sulfate sodium (DSS)-induced colitis mouse model. Ge-OH was orally administered to C57BL/6 mice at daily doses of 30 and 120 mg kg((-1)) body weight, starting 6 days before DSS treatment and ending the day after DSS removal. Furthermore, Ge-OH 120 mg kg((-1)) dose body weight was administered via enema during the acute phase of colitis to facilitate its on-site action. The results show that orally or enema-administered Ge-OH is a powerful antimicrobial agent able to prevent colitis-associated dysbiosis and decrease the inflammatory systemic profile of colitic mice. As a whole, Ge-OH strongly improved the clinical signs of colitis and significantly reduced cyclooxygenase-2 (COX-2) expression in colonocytes and in the gut wall. Ge-OH could be a powerful drug for the treatment of intestinal inflammation and dysbiosis.

    Full Text Available (Trans-3,7-Dimethyl-2,6-octadien-1-ol, commonly called geraniol (Ge-OH, is an acyclic monoterpene alcohol with well-known anti-inflammatory, antitumoral and antimicrobial properties. It is widely used as a preservative in the food industry and as an antimicrobial agent in animal farming. The present study investigated the role of Ge-OH as an anti-inflammatory and anti-dysbiotic agent in the dextran sulphate sodium (DSS-induced colitis mouse model. Ge-OH was orally administered to C57BL/6 mice at daily doses of 30 and 120mg kg(-1 body weight, starting six days before DSS treatment and ending the day after DSS removal. Furthermore, Ge-OH 120 mg kg(-1 dose body weight was administered via enema during the acute phase of colitis to facilitate its on-site action. The results show that orally or enema-administered Ge-OH is a powerful antimicrobial agent able to prevent colitis-associated dysbiosis and decrease the inflammatory systemic profile of colitic mice.

    Obstructive sleep apnoea (OSA) is one of the most common sleep disorders in elderly and represents a special problem for elderly patients. Elderly patients use a large number of drugs that might have an influence on the upper airway structure, anxiolytics or benzodiazepines being the most common. The aim of this study was to examine the effectiveness of mild or moderate OSA treatment with mandibular advance oral appliance in older lorazepam users compared with the age-matched lorazepam-free patients. A total of 40 functionally independent patients with the age of 65-74 were enrolled in the study. All included patients were found to suffer from at least two of the existing OSA symptoms (snoring, sleep fragmentation, daytime sleepiness) and were diagnosed with mild or moderate OSA after nocturnal polysomnography. Patients were divided into two groups. The experimental group consisted of 20 patients who used lorazepam in their daily therapy, and a control group consisted of 20 patients who did not take lorazepam. A mandibular advance appliance was made individually for each patient. Patients involved in the study were not overweight and were suggested to practise sleeping on the side and reduce alcohol consumption during the study. The study has shown that mandibular advance oral appliances were responsible for complete control of the OSA in over 37% of cases (15 patients). Patients have also reported substantial improvement in the symptoms; 80% of them reported that they had snored less, slept better (94%) and have not experienced daytime sleepiness (100%).

    The objective was to characterise the hormonal composition of follicular fluid from mares with distinct anovulatory-cystic follicles. Follicular fluid was aspirated from six mares that presented with cystic follicles and from pre-ovulatory follicles of five normal mares (controls). Differences in progesterone, oestradiol, testosterone, IGF-I and IGF binding were analysed using Fisher's exact test. There were greater (P < 0.03) follicular fluid oestradiol concentrations in normal follicles and the testosterone concentration of the cystic fluid was greater (P < 0.05) than that of the normal fluid. There also was a greater (P < 0.03) percentage of IGF-I binding and lower (P < 0.02) IGF-I concentrations in the fluid collected from the cystic structures compared with the fluid from normal follicles. Despite the limited number of animals, the fact that fluid aspirated from cystic follicles had higher testosterone and lower oestradiol concentrations could be of diagnostic value when a practitioner wants to distinguish between a cystic and non-cystic persistent follicle. The research reported here also indicates a likely role for the IGF system in the pathogenesis of the development and maintenance of anovulatory follicular structures in mare ovaries.

    To determine whether less invasive endometrial (EM) aspiration biopsy is adequately accurate for evaluating treatment outcomes compared to the dilatation and curettage (D&C) biopsy in early-stage endometrial cancer (EC) patients treated with high dose oral progestin and levonorgestrel intrauterine system (LNG-IUS). We conducted a prospective observational study with patients younger than 40 years who were diagnosed with clinical stage IA, The International Federation of Gynecology and Obstetrics grade 1 or 2 endometrioid adenocarcinoma and sought to maintain their fertility. The patients were treated with medroxyprogesterone acetate 500 mg/day and LNG-IUS. Treatment responses were evaluated every 3 months. EM aspiration biopsy was conducted after LNG-IUS removal followed D&C. The tissue samples were histologically compared. The diagnostic concordance rate of the two tests was examined with κ statistics. Twenty-eight pairs of EM samples were obtained from five patients. The diagnostic concordance rate of D&C and EM aspiration biopsy was 39.3% (κ value=0.26). Of the seven samples diagnosed as normal with D&C, three (42.8%) were diagnosed as normal by using EM aspiration biopsy. Of the eight samples diagnosed with endometrioid adenocarcinoma by using D&C, three (37.5%) were diagnosed with endometrioid adenocarcinoma by using EM aspiration biopsy. Of the 13 complex EM hyperplasia samples diagnosed with the D&C, five (38.5%) were diagnosed with EM hyperplasia by using EM aspiration biopsy. Of the samples obtained through EM aspiration, 46.4% were insufficient for histological evaluation. To evaluate the treatment responses of patients with early-stage EC treated with high dose oral progestin and LNG-IUS, D&C should be conducted after LNG-IUS removal.

    Full Text Available Acute iron poisoning in humans has not been adequately studied. Toxicity depends on the severity of iron overload. Manifestation of acute iron poisoning, defined as a serum iron concentration >300 µg/dL (55 µmol/L within 12 hours of ingestion, by oral route include numerous symptoms which appear in progressive stages.  Systemic toxicity is expected with an ingestion of 60 mg/kg.  A 27 year old female nurse presented to hematology department with iron toxicity 1 week after self-injecting herself with 20 ampoules of IV iron (4000 mg elemental iron, 60 mg/kg. Her vital signs were stable but she had mild hepatic tenderness.

    Full Text Available Hepatic veno-occlusive disease (VOD remains one of the commonest and most serious complications after myeloablative hematopoietic stem cell transplantation (HSCT. Clinical diagnosis of hepatic VOD is based on the finding of the triad of painful hepatomegaly, hyperbilirubinemia, and unexplained fluid retention occurring within 21 days of the transplant. However, the uncommon clinical entity of late-onset VOD can occur even beyond 20 days and should be considered in the differential diagnosis of any liver disease of more than 3 weeks′ duration. While mild cases usually resolve spontaneously, severe VOD is associated with a grim prognosis. Defibrotide, a polydisperse mixture of single-stranded oligonucleotide with antithrombotic and fibrinolytic effects on microvascular endothelium, has emerged as an effective and safe therapy for patients with severe VOD. We describe a patient who presented 55 days post transplant with clinical features suggestive of VOD. Upon treatment with oral defibrotide, he showed complete resolution of the VOD.

    Nuclear receptor subfamily 4 group A member1 (NR4A1), an orphan nuclear receptor, is involved in the transcriptional regulation of thecal cell androgen biosynthesis and paracrine factor insulin-like 3 (INSL3) expression. Androgens are known to play an important regulatory role in ovarian follicle growth. Using a chronically androgenized rat model, a preantral follicle culture model and virus-mediated gene delivery, we examined the role and regulation of NR4A1 in the androgenic control of preantral follicular growth. In the present study, Ki67 staining was increased in preantral follicles on ovarian sections from 5α-dihydrotestosterone (DHT)-treated rats. Preantral follicles from DHT-treated rats cultured for 4 d exhibited increased growth and up-regulation of mRNA abundance of G(1)/S-specific cyclin-D2 (Ccnd2) and FSH receptor (Fshr). Similarly, DHT (1 μm) increased preantral follicular growth and Ccnd2 and Fshr mRNA abundance in vitro. The NR4A1 expression was high in theca cells and was down-regulated by DHT in vivo and in vitro. Forced expression of NR4A1 augmented preantral follicular growth, androstenedione production, and Insl3 expression in vitro. Inhibiting the action of androgen (with androgen receptor antagonist flutamide) or INSL3 (with INSL3 receptor antagonist INSL3 B-chain) reduced NR4A1-induced preantral follicular growth. Furthermore, NR4A1 overexpression enhanced DHT-induced preantral follicular growth, a response attenuated by inhibiting INSL3. In conclusion, DHT promotes preantral follicular growth and attenuates thecal NR4A1 expression in vivo and in vitro. Our findings are consistent with the notion that NR4A1 serves as an important point of negative feedback to minimize the excessive preantral follicle growth in hyperandrogenism.

    Full Text Available We report three elderly patients with follicular lymphoma in situ (FLIS each highlighting a unique pattern of disease presentation and progression. The first patient had incidentally detected FLIS with peripheral blood spill and yet had an 11-year uneventful follow up. The second patient with an overt follicular lymphoma (FL developed high-grade transformation in jejunum with FLIS extensively involving the Payers patches. The third patient had a FLIS but that qualified as higher grade and was treated in spite of lack of overt FL mainly because of higher grade and patient subsequently did develop overt FL. The first case of typical FLIS confirms that peripheral blood spill does not connote poor prognosis in FLIS, the second case illustrates that FLIS may colonize mucosa-associated lymphoid tissue as part of homing in process of a disseminated FL and the third case validates the aggressive nature of high-grade FLIS.

    Metastatic tumors are the most common tumors of the spine, accounting for 98% of all spine lesions. But spinal cord compression as the initial presentation of metastatic occult follicular carcinoma without any thyroid enlargement is unusual and relatively rare. This report describes a 35-years-old female patient presenting with paraplegia and urinary incontinence for the last two months. She had no thyroid enlargement; no thyroid related symptoms and her biochemical thyroid profile was normal. Magnetic resonance imaging (MRI) of spine shows a huge mass compressing the spinal cord at D11-D12 involving both the spinal and paraspinal areas. The patient was treated by surgery and radioiodine ablation as the histopathology showed metastatic follicular thyroid carcinoma. This case was reported because of the rarity of the disease. Early diagnosis and initiation of the treatment should promise a good prognosis for a patient with metastatic spinal cord compression.

    Objective: To evaluate the therapeutic effect of Yangxin Fumai Oral Liquid (YFOL,养心复脉口服液), a Chinese herbal medicine for nourishing Heart and restoring pulse, in treating patients with extrasystole. Methods: The effect of YFOL was observed in treating 30 patients with different kinds of extrasystole and compared with that in 30 patients treated by propafenone. The effect of YFOL on experimental arrhythmia was studied in animals as well. Results: Clinical observation showed that the effect of treatment against extrasystole in the two groups was similar, but the YFOL group showed better results in symptom improvement (P<0.01) with no marked side-effect. Experimental study showed that YFOL could reduce the chloroform induced ventricular fibrillation occurrence in mice, delay the initiating time of ventricular extrasystole, tachycardia and fibrillation induced by aconitine, BaCl2 and coronary artery ligation in rats, or shorten the lasting time of arrhythmia, reduce the attacking frequency of ventricular extrasystole. There was significant difference in comparing with the control group (P<0.05, P<0.01). Conclusion:YFOL is a good and convenient Chinese herbal preparation for different kinds of extrasystole with few toxic and side-effect in clinical practice.

    During two years (1997-1999) an investigation of possible infections of chlamydial etiology in outpatients with follicular conjunctivitis was carried out, through the use of specific assays. Fifty-seven selected patients with presumptive inclusion conjunctivitis were diagnosed by means of ophthalmoscopic examination and bilateral tarsal-conjunctiva swabbing for microorganisms. The possible presence of Chlamydia trachomatis was tested by immunofluorescence microscopy and isolation in cell culture of McCoy line. Of the 57 conjunctivitis patients screened, 37 (65%) proved to be positive by cell culture (CC) and 27 (47%) by direct immunofluorescence (IFD). A good agreement between the two assays was observed, where the CC was more sensitive than IFD. Of these 37 patients with chlamydial conjunctivitis, 23 (62%) were women, with over one-third of them ranging in age from 45 to 65 years. Their clinical records revealed an evolution period of 1 to 12 months. Eighteen (78%) of these women reported previous genital pathology, while 4 (29%) of the 14 men had a history of urethritis by Chlamydia trachomatis. A high frequency of follicular conjunctivitis by Chlamydia (65%) in the screened patients was observed, without any evidence of urogenital signs and symptoms at the moment of the study.

    Full Text Available Follicular lymphoma (FL is the most common indolent non-Hodgkin lymphoma, typically affected mature adults and elderly, with a median age at diagnosis of 65 years. The natural history of FL appears to have been favorably impacted by the introduction of Rituximab. Randomized clinical trials have demonstrated that the addition of rituximab to standard chemotherapy induction has improved the overall survival and new strategies of chemo-immunotherapy, such as Bendamustine combined with Rituximab, showed optimal results on response and lower hematological toxicity, becoming one of the standard treatments, particularly in elderly. Moreover maintenance therapy with Rituximab demonstrated improvement of progression-free survival. Despite these exciting results, FL is still an incurable disease. It remains a critical unmet clinical need finding new prognostic factors to better identify poor outcome patients, to reduce the risk of transformation and to explore new treatment strategies, especially for patients not candidate to intensive chemotherapy regimens, such as elderly patients. Some progresses were already done with novel agents, but larger and more validated studies are needed. Elderly patients are the larger portion of patients with FL and represent a subgroup with higher treatment difficulties, because of comorbidities and smaller spectrum for treatment choice. Further studies, focused on elderly follicular lymphoma patients, with their peculiar characteristics, are needed in order to define the best tailored treatment at diagnosis and at the time of relapse in this setting.

    The phase transition of pharmaceutical excipients that can be induced by humidifying or heating is well-known to increase the hardness of orally disintegrating tablets (ODTs). However, these conditions are not applicable to drug substances that are chemically unstable against such stressors. Here, we describe a system which enhances the hardness of tablets containing water-insoluble polymers by using high-pressure carbon dioxide (CO2). On screening of 26 polymeric excipients, aminoalkyl methacrylate copolymer E (AMCE) markedly increased tablet hardness (+155N) when maintained in a high-pressure CO2 environment. ODTs containing 10% AMCE were prepared and treatment with 4.0MPa CO2 gas at 25°C for 10min increased the hardness to +30N, whose level corresponded to heating at 70°C for 720min. In addition, we confirmed the effects of CO2 pressure, temperature, treatment time, and AMCE content on the physical properties of ODTs. Optimal pressure of CO2 gas was considered to be approximately 3.5MPa for an AMCE formula, as excessive pressure delayed the disintegration of ODTs. Combination of high-pressure CO2 gas and AMCE is a prospective approach for increasing the tablet hardness for ODTs, and can be conducted without additional heat or moisture stress using a simple apparatus.

    Antibiotics excreted into the intestinal tract, such as broad-spectrum cephalosporins, disrupt the indigenous microflora, affect colonization resistance (CR), and promote intestinal colonization by resistant bacteria. We tested whether oral DAV131, a charcoal-based adsorbent, would prevent colonization by a cefotaxime (CTX)-resistant Klebsiella pneumoniae strain (PUG-2) in CTX-treated mice. Mice received CTX, saline, CTX and DAV131, or saline and DAV131 for 3 days before oral challenge with 106 CFU of PUG-2. The fecal CTX concentrations and counts of PUG-2 were assayed. Fecal CTX disappeared when DAV131 was given concomitantly with CTX (P < 0.05), and the area under the curve of PUG-2 fecal density was significantly reduced (P < 0.01). In conclusion, reducing intestinal antibiotic exposure with DAV131 may reduce colonization by resistant strains during treatment compared to treatment with CTX only. This might open new possibilities for decreasing the impact of antibiotics on the intestinal microbiota during treatments. PMID:23959311

    Full Text Available The aim of this study was to evaluate the influence of 3% ethanol extract of propolis (EEP on hygiene, gingival and microbiological status of oral cavity in patients with cleft lip and palate treated with fixed orthodontic appliances. The study included forty-one nonsyndromic complete unilateral of bilateral cleft lip and palate subjects with fixed appliance on at least 10 teeth. Twenty-one subjects were instructed to brush their teeth three times a day using toothpaste with propolis. Control group included twenty subjects who were asked to brush their teeth three times a day using a toothpaste without propolis. API, OPI, GI, and supragingival bacterial plaque were taken from each subject twice: baseline and after using the toothpaste for 35 days. The final examinations showed statistically significant decrease in OPI, GI, and the percentage of the Actinomyces spp. and Capnocytophaga spp. compared with baseline in propolis group subjects. The improvement in oral health in these patients confirms antibacterial, anti-inflammatory, and regenerative properties of propolis.

    A pyogenic granuloma is a tumorlike proliferation that occurs slightly more often in females, frequently involving the gingiva in the maxillary region. Clinically, it presents as a sessile or pedunculated exophytic mass with a smooth or lobulated surface, which tends to bleed easily. Its color can range from pink to dark red. The most common treatment is surgical excision. This case report presents a pyogenic granuloma that formed around an implant 7 years after its insertion. Pyogenic granulomas associated with dental implants are extremely rare; this is the fourth reported case and the first case of pyogenic granuloma to be treated with an Er:YAG laser.

    Src tyrosine kinases are overexpressed in pancreatic cancers, and the oral Src inhibitor saracatinib has shown antitumor activity in preclinical models of pancreas cancer. We performed a CTEP-sponsored Phase II clinical trial of saracatinib in previously treated pancreas cancer patients, with a primary endpoint of 6-month survival. A Simon MinMax two-stage phase II design was used. Saracatinib (175 mg/day) was administered orally continuously in 28-day cycles. In the unselected portion of the study, 18 patients were evaluable. Only two (11%) patients survived for at least 6 months, and three 6-month survivors were required to move to second stage of study as originally designed. The study was amended as a biomarker-driven trial (leucine rich repeat containing protein 19 [LRRC19] > insulin-like growth factor-binding protein 2 [IGFBP2] "top scoring pairs" polymerase chain reaction [PCR] assay, and PIK3CA mutant) based on preclinical data in a human pancreas tumor explant model. In the biomarker study, archival tumor tissue or fresh tumor biopsies were tested. Biomarker-positive patients were eligible for the study. Only one patient was PIK3CA mutant in a 3' untranslated region (UTR) portion of the gene. This patient was enrolled in the study and failed to meet the 6-month survival endpoint. As the frequency of biomarker-positive patients was very low (pancreatic cancer patients treated with a Src inhibitor based on a biomarker would improve 6-month survival, we demonstrate that testing pancreatic tumor samples for a biomarker-driven, multicenter study in metastatic pancreas cancer is feasible.

    Ciprofloxacin is a fluorinated carboxyquinolone that inhibits Enterobacteriaceae, staphylococci, and Pseudomonas at low concentrations. It has poor activity against Bacteroides fragilis. In this study, the effect of administration of ciprofloxacin on bowel flora was determined in patients treated for different infections. Patients, aged 22 to 70 years, were treated with 500 mg of ciprofloxacin every 12 hours or 750 mg every eight hours for seven to 42 days. Some patients had advanced cystic fibrosis; other patients had infections with resistant bacteria. Infecting organisms were Pseudomonas aeruginosa, Staphylococcus aureus, Serratia, and Acinetobacter. Sites of infections were lung, soft tissue, and urinary tract. Stool samples were evaluated initially, during therapy, and after therapy. No resistant gram-negative aerobic species emerged; five patients had yeast colonization, staphylococci were found in three patients, and streptococci were found in one patient. Ciprofloxacin did not select resistant gram-negative bacteria in the stool, although sputum isolates showed increases in minimal inhibitory concentrations. Resistant bacteria were not selected in the fecal flora of patients who had received beta-lactam and aminoglycoside antibiotics before therapy with ciprofloxacin.

    The idea of identifying oral lesions with a precancerous nature, i.e. in the sense of pertaining to a pathologic process with an increased risk for future malignant development, of course is to prevent frank malignancy to occur in the affected area. The most common oral lesion with a precancerous...... nature is oral leukoplakia, and for decades it has been discussed how to treat these lesions. Various treatment modalities, such as systemic therapies and surgical removal, have been suggested. The systemic therapies tested so far include retinoids, extracts of green tea, inhibitors of cyclooxygenase-2...

    Oral rehydration solution (ORS) is used to treat the dehydration caused by diarrhoeal diseases, including cholera. ORS formulations with an osmolarity (a measure of solute concentration) of ≤ 270 mOsm/L (ORS ≤ 270) are safe and more effective than ORS formulations with an osmolarity of ≥ 310 mOsm/L (ORS ≥ 310) for treating non-cholera diarrhoea. As cholera causes rapid electrolyte loss, it is important to know if these benefits are similar for people suffering from cholera. To compare the safety and efficacy of ORS ≤270 with ORS ≥ 310 for treating dehydration due to cholera. We searched the Cochrane Infectious Disease Group Specialized Register (April 2011), CENTRAL (The Cochrane Library Issue 4, 2011), MEDLINE (1966 to April 2011), EMBASE (1974 to April 2011), and LILACS (1982 to April 2011). We also contacted organizations and searched reference lists. Randomized controlled trials comparing ORS ≤ 270 with ORS ≥ 310 for treating adults and children with acute diarrhoea due to cholera. Two reviewers independently applied eligibility criteria, assessed trial quality, and extracted data. We pooled dichotomous data using risk ratio (RR), pooled continuous data using mean difference (MD) or the standardized mean difference (SMD), and presented the results with 95% confidence intervals (CI). For glucose-based ORS, seven trials (718 participants) met the inclusion criteria. Biochemical hyponatraemia (blood sodium levels cholera, ORS ≤ 270 is associated with biochemical hyponatraemia when compared with ORS ≥ 310, but there are no differences in terms of other outcomes. Although this risk does not appear to be associated with any serious consequences, the total patient experience in existing trials is small. Under wider practice conditions, especially where patient monitoring is difficult, caution is warranted.

    The objective of the present study was to evaluate sphingolipid levels (sphingosine-So and sphinganine-Sa) and to compare the Sa/So ratio in liver, serum and urine of Wistar rats after prolonged administration (21 days) of fumonisin B1 (FB1). In parallel, the kinetics of sphingolipid elimination in urine was studied in animals receiving a single dose of FB1. Prolonged exposure to FB1 caused an increase in Sa levels in urine, serum and liver. The most marked effect on sphingolipid biosynthesis was observed in animals treated with the highest dose of FB1. Animals receiving a single dose of FB1 presented variations in Sa and So levels and in the Sa/So ratio. PMID:19333435

    In mammals, ovarian follicle is made of an oocyte with its surrounding granulosa cells and theca cells. Follicular growth and development is a highly coordinated programmable process, which guarantees the normal oocyte maturation and makes it having the fertilizing capacity. The paracrine and autocrine between oocytes and granulosa cells are essential for the follicular development to provide a suitable microenvironment. Phosphatidylinositol-3 kinase /protein kinase B is one of these important regulatory signaling pathways during this developmental process, and bone morphogenetic protein-15 an oocyte-specific secreted signal molecule, which regulates the follicular development by paracrine in the mammalian ovary. The present article overviewed the role of phosphatidylinositol-3 kinase / protein kinase B signaling during the follicular development based on our previous investigation about protein kinase B /forkhead transcription factor forkhead family of transcription factors -3a, and then focused on the regulatory effects of bone morphogenetic protein-15, as a downstream signal molecule of phosphatidylinositol-3 kinase / forkhead family of transcription factors -3a pathway, on ovarian follicular development, which helped to further understand the molecular mechanism regulating the follicular development and to treat ovarian diseases like infertility.

    This study was conducted to develop a hormone protocol that precisely synchronises follicular development for a timed breeding (TB) programme in dromedary camels. To examine the effect of GnRH treatment at four known stages of follicular development, animals were treated with GnRH when the largest follicle of the wave was 4-7, 8-11, 12-17 and 18-27 mm in diameter. Transrectal ultrasonography was carried out daily up to 20 days after treatment. A hormone protocol (FWsynch) for the synchronisation of follicular wave and TB consisting of GnRH-1 (GnRH) on Day 0, PG-1 (PGF2α) on Day 7, GnRH-2 on Day 10 and PG-2 on Day 17 was initiated at four known stages of follicular development. Ovarian structures were monitored by ultrasonography. The FWsynch protocol was initiated at random stages of follicle development and animals were bred by natural mating at a fixed time at the research facility and in field. The pregnancy was diagnosed by ultrasonography. GnRH treatment in animals with a dominant follicle (DF) of ≥ 11 mm in diameter resulted in synchronous new follicular wave emergence, whereas in animals with a DF ≤ 10 mm, the treatment did not alter the development of the existing follicular wave. The FWsynch protocol was effective in synchronising the follicular wave for TB irrespective of the stage of follicular development at the beginning of the protocol. TB using FWsynch protocol resulted in a pregnancy rate of 60.2% in a research facility and 53.6% and 45.6% in normal and infertile camels respectively under field conditions.

    Introduction:Most hepatocellular carcinomas (HCC) develop in a background of underlying liver disease including chronic hepatitis B. However, the effect of antiviral therapy on the long-term outcome of patients with hepatitis B virus (HBV)-related HCC treated with chemoembolization is unclear. This study aimed to evaluate the survival benefits of anti-HBV therapy after chemoembolization for patients with HBV-related HCC. Methods:A total of 224 HCC patients who successfully underwent chemoembolization were identified, and their survival and other relevant clinical data were reviewed. Kaplan-Meier and Cox regression analyses were performed to validate possible effects of antiviral treatment on overall survival (OS). Results:The median survival time (MST) was 15.9 (95% confidence interval [CI], 9.5–27.7) months in the antiviral group and 9.6 (95% CI, 7.8–13.7) months in the non-antiviral group (log-rank test, P=0.044). Cox multivariate analysis revealed that antiviral treatment was a prognostic factor for OS (P=0.008). Additionally, a further analysis was based on the stratification of the TNM tumor stages. In the subgroup of early stages, MST was significantly longer in the antiviral-treatment group than in the non-antiviral group (61.8 months [95% CI, 34.8 months to beyond the follow-up period] versus 26.2 [95% CI, 14.5–37.7] months, P=0.012). Multivariate analysis identified antiviral treatment as a prognostic factor for OS in the early-stage subgroup (P=0.006). However, in the subgroup of advanced stages, MST of the antiviral-treated group was comparable to that of the non-antiviral group (8.4 [95%CI, 5.2–13.5] months versus 7.4 [95%CI, 5.9–9.3] months, P=0.219). Multivariate analysis did not indicate that antiviral treatment was a significant prognostic factor in this subgroup. Conclusion:Antiviral treatment is associated with prolonged OS time after chemoembolization for HCC, especially in patients with early-stage tumors.

    Full Text Available Context: Standard WHO-ORS reduces dehydration, but does not reduce stool volume and duration of diarrhea. Low osmolar ORS produce maximal water absorption. This meta-analysis was conducted to evaluate the efficacy of low osmolar ORS in comparison to standard WHO-ORS. Evidence acquisition: A systematic review and meta-analysis of Randomized Controlled Trials (RCTs comparing efficacy of low osmolar ORS and standard WHO-ORS in childhood diarrhea was carried out. RCTs were searched in PubMed, Cochrane CENTRAL, DOAJ, Google Scholar and Google. The data was extracted in Excel and entered in Review Manager 5.3 for calculation of effect sizes. Results: The outcome of stool output was reported in 9 trails. Reduced osmolarity ORS resulted in significantly reduced stool output as compared with standard WHO-ORS (pooled standardized mean difference -0.44, 95% CI -0.72 to -0.15. Information for the outcome of duration of diarrhea was available from 6 trials. The pooled standardized mean difference was -0.21 (95% CI -0.79 to 0.37, suggesting that reduced osmolarity ORS did not have significant effect on the duration of diarrhea as compared to standard WHO-ORS. The outcome of need for intravenous fluid therapy was reported in 8 trials. The meta-analysis revealed that reduced osmolarity ORS when compared to WHO standard ORS was associated with fewer unscheduled intravenous infusions (Odds Ratio 0.62, 95% CI 0.47 to 0.83. The meta-analysis for the outcome of vomiting reported in 5 clinical trials showed that children treated with low osmolar ORS were less likely to vomit than children treated with standard WHO-ORS (Odds Ratio 0.74, 95% CI 0.57 to 0.97. Conclusion: Low osmolar ORS when compared to standard WHO-ORS is associated with reduced stool output, reduction in need for unscheduled intravenous infusion and lesser episodes of vomiting. However, there was no significant difference in duration of diarrhea

  6. FDG-PET in Follicular Lymphoma Management

    Full Text Available 18-Fluoro-deoxyglucose positron emission tomography/computerised tomography (FDG PET/CT is commonly used in the management of patients with lymphomas and is recommended for both initial staging and response assessment after treatment in patients with diffuse large B-cell lymphoma and Hodgkin lymphoma. Despite the FDG avidity of follicular lymphoma (FL, FDG PET/CT is not yet applied in standard clinical practice for patients with FL. However, FDG PET/CT is more accurate than conventional imaging for initial staging, often prompting significant management change, and allows noninvasive characterization to guide assessment of high-grade transformation. For restaging, FDG PET/CT assists in distinguishing between scar tissue and viable tumors in residual masses and a positive PET after induction treatment would seem to predict a shorter progression-free survival.

    Full Text Available Follicular unit extraction (FUE is a surgical procedure, which can be used to transplant follicular units into vitiliginous areas. Such follicular unit transplant has been recently used to repigment stable vitiligo patches. FUE was done for a 12-year-old female with a stable vitiligo patch with leukotrichia on the eyebrow. Repigmentation was noted in 6 weeks and complete pigmentation seen at 12 weeks. Leukotrichia resolved over a period of 6 months. No recurrence was noted at the end of 6 months follow-up with excellent colour match. This case is presented to highlight the simplicity, safety and effectiveness of FUE in stable vitiligo patches with leukotrichia.

    The aim of this study was to assess the usefulness of positron emission tomography/computed tomography in staging, prognosis evaluation and restaging of patients with follicular lymphoma. A retrospective study was performed on 45 patients with untreated biopsy-proven follicular lymphoma who underwent {sup 18}F-fluorodeoxyglucose PET/CT (FDG PET/CT) and CT before and after chemoimmunotherapy induction treatment (rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisone). PET/CT detected more nodal (+51%) and extranodal (+89%) lesions than CT. PET/CT modified Ann Arbor staging in eight patients (18%). Five patients (11%) initially considered as being early stage (I/II) were eventually treated as advanced stage (III/IV). In this study, an initial PET/CT prognostic score was significantly more accurate than the Follicular Lymphoma International Prognostic Index score in identifying patients with poor prognosis (i.e. patients with incomplete therapeutic response or early relapse). The accuracy of PET/CT for therapeutic response assessment was higher than that of CT (0.97 vs 0.64), especially due to its ability to identify inactive residual masses. In addition, post-treatment PET/CT was able to predict patients' outcomes. The median progression-free survival was 48 months in the PET/CT-negative group as compared with 17.2 months for the group with residual uptake (p < 10{sup -4}). FDG PET/CT is useful for staging and assessing the prognosis and therapeutic response of patients with follicular lymphoma. (orig.)

    The purpose of the present study is to understand the pharmacokinetic feature of mefloquine measured by erythrocytes and plasma in Schistosoma japonicum (S. j.)-infected mice and non-infected mice after oral administration of the drug at single doses. A high-performance liquid chromatography (HPLC) method was used to measure the plasma and erythrocyte concentrations of mefloquine at varying intervals posttreatment. Our results demonstrated that in non-infected mice treated orally with mefloquine at an ineffective dose of 50 mg/kg or effective dose of 200 mg/kg for 2-72 h, the erythrocyte-to-plasma ratios of mefloquine were 5.8-11.2 or 2-14.2. On the other hand, in S. j.-infected mice treated with the same single doses of the drug, the erythrocyte and plasma drug concentration ratios were 3.1-4.6 or 2.9-8.5, manifesting that either in infected mice or in non-infected mice that received oral mefloquine resulted in higher concentration of mefloquine in erythrocytes than that in plasma. Unexpectedly, under oral administration of mefloquine at a higher single dose of 200 mg/kg, the pharmacokinetic parameter C max values for plasma from S. j.-infected and non-infected mice were 1.6 ± 0.3 and 2.0 ± 0.4 μg/mL, respectively, which were below the determined in vitro LC50 (50 % lethal concentration) value of 4.93 μg/mL. Therefore, the plasma concentration of mefloquine may display a little effect against schistosomes during the treatment. Although the values of T 1/2 and AUC0-∞ for erythrocytes were significantly longer and higher in infected mice than those of corresponding non-infect mice that received the same single mefloqine dose of 50 mg/kg, the C max value was only 2.6 ± 0.4 μg/mL lower than the determined in vitro LC50, which may explain why this low single dose is ineffective against schistosomes in vivo. After administration of higher mefloquine dose of 200 mg/kg, the C max value for erythrocytes in infected mice was 30 % (7.4 ± 0

    Full Text Available Abstract Introduction Breast involvement by non-Hodgkin lymphoma is particularly rare in men. We describe the case of a patient with a rapidly growing, painless gynecomastia-like nodule in the left breast. On ultrasonography, the nodule was suspicious for breast carcinoma. Case presentation A breast biopsy from a 54-year-old Caucasian man showed the morphoimmunophenotypical features of grade 3 follicular lymphoma. Moreover, fluorescence in situ hybridization analysis showed a t(14,18 translocation suggesting breast involvement by a systemic lymphoma rather than a primary breast lymphoma. The histological diagnosis was subsequently confirmed after nodule excision. Mediastinal and abdominal node involvement was then identified on computed tomography and positron emission tomography scans during staging examinations. Our patient was treated with chemotherapy. After three years our patient experienced a right retro-areolar relapse. He then received two further cycles of chemotherapy but developed a myeloid acute leukemia and, as a result of this, he subsequently died. Conclusions The rarity of breast lymphomas, especially in men, and the problems related to the therapeutic choices with these tumors require molecular techniques in association with classical histological diagnosis.

    Full Text Available Thyroid cancer and thyroid nodules are more prevalent in women than men, so female sex hormones may have an etiological role in these conditions. There are no data about direct effects of progesterone on thyroid cells, so the aim of the present study was to evaluate progesterone effects in the sodium-iodide symporter NIS, thyroglobulin TG, thyroperoxidase TPO, and KI-67 genes expression, in normal thyroid follicular cells, derived from human tissue. NIS, TG, TPO, and KI-67 mRNA expression increased significantly after TSH 20 μUI/mL, respectively: 2.08 times, P<0.0001; 2.39 times, P=0.01; 1.58 times, P=0.0003; and 1.87 times, P<0.0001. In thyroid cells treated with 20 μUI/mL TSH plus 10 nM progesterone, RNA expression of NIS, TG, and KI-67 genes increased, respectively: 1.78 times, P<0.0001; 1.75 times, P=0.037; and 1.95 times, P<0.0001, and TPO mRNA expression also increased, though not significantly (1.77 times, P=0.069. These effects were abolished by mifepristone, an antagonist of progesterone receptor, suggesting that genes involved in thyroid cell function and proliferation are upregulated by progesterone. This work provides evidence that progesterone has a direct effect on thyroid cells, upregulating genes involved in thyroid function and growth.

    Objective: To improve understanding of the characteristics of follicular bronchiolitis(FB). Methods: The clinical data of 3 patients with FB confirmed by thoracoscopic lung biopsy were retrospectively analyzed. A literature search was performed with "follicular bronchiolitis" as the key word in China Knowledge Resource Integrated Database, Wanfang and PubMed, Ovid Database. The time interval was from January 1947 to December 2015. Related articles of FB were retrieved and the clinical, radiographic characteristics and prognosis were analyzed. Results: Among the 3 patients, 1 was male and 2 were female, aging 32-55 years. Two patients were asymptomatic, and 1 patient presented with fever, cough and dyspnea. Two patients showed normal pulmonary ventilatory function with decreased diffusive function, and 1 patient showed normal pulmonary function. The predominant HRCT findings were bilateral multiple small nodules and cystic opacities, patchy ground-glass opacities, reticular opacities and traction bronchiectasis. The pathological examination by thoracoscopic biopsy revealed bronchiolar and peribronchiolar lymphoid follicles. All patients were treated with corticosteroids, with 2 patients receiving immunosuppressants. Follow-up HRCT after 1-2 months showed no improvement, and further follow-up HRCT after 2-4 years revealed no change in 2 patients while the other patient had increased pulmonary nodules and cystic opacities. Seventeen articles concerning FB with complete records were included in the literature review. A total of 64 patients were reported in these articles. The typical images were bilateral multiple small nodules and ground-glass opacities, reticular opacities, and cystic opacities. The majority of patients improved after treatment of corticosteroids and (or) immunosuppressants. But our 3 cases showed no improvement. Conclusions: FB is a rare small airway disease which has non-specific clinical manifestations and pulmonary function. The most common

    Oral disease is exceedingly common in small animal patients. In addition, there is a very wide variety of pathologies that are encountered within the oral cavity. These conditions often cause significant pain and/or localized and systemic infection; however, the majority of these conditions have little to no obvious clinical signs. Therefore, diagnosis is not typically made until late in the disease course. Knowledge of these diseases will better equip the practitioner to effectively treat them. This article covers the more common forms of oral pathology in the dog and cat, excluding periodontal disease, which is covered in its own chapter. The various pathologies are presented in graphic form, and the etiology, clinical signs, recommended diagnostic tests, and treatment options are discussed. Pathologies that are covered include: persistent deciduous teeth, fractured teeth, intrinsically stained teeth, feline tooth resorption, caries, oral neoplasia, eosinophilic granuloma complex, lymphoplasmacytic gingivostomatitis, enamel hypoplasia, and "missing" teeth.

    Full Text Available Objective: This study aimed to examine the safety of 5-aminolevulinic acid phosphate (5-ALA with sodium ferrous citrate (SFC in diabetic patients treated with one or more oral hypoglycemic agents (OHAs. Background: Recent intervention studies performed in the USA and Japan have shown that a nutritional supplement of 5-ALA with SFC efficiently reduced blood glucose levels in pre-diabetic population without any adverse events. Thus, it was anticipated that 5-ALA with SFC may potentially be taken as a beneficial supplement by diabetic patients who were being treated with OHA therapy. Nevertheless, it is important to examine its safety and efficacy in diabetic population. Methods: This study was a prospective single-blinded, randomized, placebo-controlled and parallel-group comparison study. Medically treated diabetic patients between the ages of 30 and 75 were recruited from the Tokyo metropolitan area of Japan and 45 subjects were selected after screening. These subjects were randomly assigned to three groups: daily intake of 15mg 5-ALA, 50mg 5-ALA, and a placebo (n=15, respectively. The supplement or placebo was administered for 12 weeks followed by a four week washout period. The primary endpoint was safety and occurrence of hypoglycemic attack, while the secondary endpoint was changes of fasting blood glucose (FBG and hemoglobin A1c (HbA1c. Results: Adverse events related to 5-ALA with SFC were not observed in all the groups. Abnormalities in blood and urine tests were not observed either. Significant decrease in FBG was not detected in all the groups. However, there was a small but significant decrease in HbA1c at 4 and 8 week in the 15 mg 5-ALA group. Significant decrease in HbA1c was not observed in the 50 mg 5-ALA group, although a tendency to decrease after 4 weeks was apparent. Conclusion: 5-ALA with SFC is a safe and potentially beneficial supplement if taken by diabetic patients treated with OHAs.

    The objective of the study was to compare the pregnancy rates in PCOS patients undergoing clomiphene citrate (CC) and intrauterine insemination (IUI) treatment with different leading follicular sizes. A total of 358 infertile women with PCOS who underwent 563 clomiphene citrate and IUI treatment cycles were included in this prospective study. Treatment cycles were divided into three groups according to leading follicular size on the day of hCG administration: Group I: follicular size 17-18 mm (n = 177), Group II: 19-22 mm (n = 321), and Group III : >22 mm (n = 65). Pregnancy rates were evaluated. Treatment outcomes of the groups were further analyzed related to endometrial thickness measurement on the day of hCG. For this purpose, cycles were placed into three subgroups as follows: endometrial thickness 9 mm. There was no statistically significant difference in clinical pregnancy rate per cycle between the groups (8.5, 10, and 9.2 % for Group I, II, and III, respectively, p = 0.86). In further analyses related to endometrial thickness, no significant difference was also found in pregnancy rate among the groups. This results suggest that pregnancy rate is not related to leading follicle size on the day of hCG administration in PCOS patients treated with CC and IUI. In addition, pregnancy rate in women with different follicular sizes is not influenced by the endometrial thickness.

    To analyse the clinical characteristics and management of patients with non-valvular atrial fibrillation (NVAF) treated with direct oral anticoagulants (DOAC). Observational, cross-sectional and multicentre study. Autonomous Communities in which the general practitioner can prescribe DOAC (n=9). The study included a total of 790 patients on chronic treatment with anticoagulants, and on whom therapy was changed, as well as being currently on treatment with DOAC for at least for 3 months. A record was made of the sociodemographic and clinical management date. Mean age was 78.6±8.4 years, and 50.5% of patients were men. Mean CHADS2 score was 2.6±1.2, mean CHA2DS2-VASc score was 4.3±1.6, and the mean HAS-BLED score was 2.3±1.0. Mean duration of treatment with DOAC was 15.8±12.5 months. Rivaroxaban was the DOAC most frequently prescribed (57.8%), followed by dabigatran (23.7%), and apixaban (18.5%). Of the patients receiving rivaroxaban, 70.2% were taking the dose of 20mg/daily. Of the patients receiving dabigatran, 41.7% were taking the dose of 150mg twice daily, and in the case of apixaban, 56.2% were taking the dose of 5mg twice daily. Satisfaction (ACTS Burdens scale 52.0±7.2 and ACTS Benefits scale 12.1±2.2), and therapeutic adherence (97.8% of patients took their medication regularly) with DOAC were high. Patients treated with DOAC in Spain have a high thromboembolic risk. A significant proportion of patients receive a lower dose of DOAC than that recommended according to their clinical profile. Satisfaction and medication adherence are high. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    To compare all-cause health care utilization and costs between patients with schizophrenia treated with once monthly paliperidone palmitate (PP1M; Invega Sustenna (1) ) and atypical oral antipsychotic therapy (OAT). This was a retrospective claims-based analysis among adult California Medicaid (Medi-Cal) patients with schizophrenia having ≥2 claims for PP1M or OAT from 1 July 2009 to 31 December 2013 and continuous health plan enrollment for ≥1 year pre- and post-index date (PP1M or OAT initiation date). Baseline characteristics were reported descriptively. Propensity score matching with a 1:1 greedy match method was used to create two matched cohorts. Treatment patterns, all-cause health care utilization, and costs for the 12 month follow-up period were compared between the two matched cohorts. Two well matched cohorts of 722 patients were produced with similar baseline characteristics. During the 12 month follow-up period, PP1M patients were significantly less likely to discontinue treatment (30.6% vs. 39.5%, p costs ($5060 vs. $10,880, p costs were significantly higher in the PP1M cohort ($16,347 vs. $9115, p costs were not significantly different between the matched cohorts ($25,546 vs. $25,307, p = 0.853). Patients with schizophrenia treated with PP1M had significantly fewer inpatient hospitalizations and associated costs with no significant difference in the total costs between the two cohorts. This study is subject to limitations associated with claims data such as miscoding, inability to examine clinical severity, etc.

    A patient who worked at the World Trade Center (WTC) site presented with right cervical lymphadenopathy. He underwent right neck dissection. The final pathology showed follicular dendritic cell sarcoma. He was treated with radiation and chemotherapy and remained free of disease initially. He then presented with left cervical lymphadenopathy 2.5 years later and underwent a left neck dissection with similar pathology. A discussion of the disease process and WTC exposure is presented. Clinicians should be cognisant of this disease process and the latency between WTC exposure and the onset of sarcomas. 2015 BMJ Publishing Group Ltd.

    Follicular bronchiolitis (FB) is a rare small-airway pathology that is associated mainly with connective tissue diseases. This case report presents a new, diagnosed, different airway disease in a non-smoker with rheumatoid arthritis in remission who was treated for presumed asthma, but was not controlled. She was ultimately diagnosed with FB after video-assisted thoracoscopic surgery. The clinical findings of FB were controlled successfully by colchicine after she did not respond to systemic steroid therapy. This is the first case report of FB associated with rheumatoid arthritis that responded to colchicine.

    Reverse transcription quantitative polymerase chain reaction (RT-qPCR) has become a frequently used strategy in gene expression studies. The relative quantification method is an important and commonly used method for the evaluation of RT-qPCR data. The key of this method is to identify an applicable internal control gene because the usage of different internal control genes may lead to distinct conclusions. Herein, we report the validation of 12 common housekeeping genes for RT-qPCR for gene expression analysis in the Oral squamous cell carcinoma (OSCC) cell line (KB and Tca-8113) treated by 5 kinds of Chemotherapy Drugs. The gene expression stability and applicability of the 12 housekeeping gene candidates were determined using the geNorm, NormFinder, and BestKeeper software programs. Comprehensive analyzing the results of the three software, ALAS1/GAPDH, ALAS1 and GUSB were suggested to be the most stable candidate genes for the study of both KB and Tca-8113 cell line together, KB cell line, and Tca-8113 cell line, respectively. This study provides useful information to normalize gene expression accurately for the investigation of target gene profiling in cell lines of OSCC. Further clarification of tumor molecular expression markers with our recommended housekeeping genes may improve the accuracy of diagnosis and estimation of prognostic factors as well as provide novel personalized treatments for OSCC patients.

    Full Text Available Present investigation was aimed at developing biodegradable polymeric microspheres of Tetracycline hydrochloride to treat oral infections by using Poly (D, L lactic-co-glycolic acid (50:50 as polymer. Microspheres were prepared using oil-in-oil (O/O and water-in-oil-in-water (W/O/W double emulsion solvent evaporation method. Microspheres prepared by W/O/W were spherical in shape compared those prepared with O/O method. Thus, the microspheres formulated by W/O/W method were further evaluated for particle size, morphology, entrapment efficiency, and percent drug release. Effects of salt addition, polymer concentration on the characteristics of microspheres and tetracycline release profile were investigated. An increase in polymer concentration decreased drug release and increased entrapment efficiency of drug. In vitro studies indicated that release of drug from microspheres could be controlled for 10-15 days depending on drug: Polymer concentration. Formulation E released 99.10% of drug from microspheres in 10 days. Addition of sodium chloride to outer aqueous phase produced spherical microspheres with smooth surface and also increased entrapment efficiency. Microspheres were further dispersed in optimized formulation of mucoadhesive in situ gel of Pluronic F127, which acts as carrier for microspheres. In vivo studies were conducted on patients who underwent molar tooth extraction to check efficacy of designed formulation.

    Full Text Available Follicular lymphoma (FL is an indolent malignancy of germinal center B cells with varied incidence across racial groups and geographic regions. Improvements in the classification of non-Hodgkin lymphoma subtypes provide an opportunity to explore associations between environmental exposures and FL incidence. Our paper found that aspects of Western lifestyle including sedentary lifestyle, obesity, and diets high in meat and milk are associated with an increased risk of FL. Diets rich in fruits and vegetables, polyunsaturated fatty acids, vitamin D, and certain antioxidants are inversely associated with FL risk. A medical history of Sjogren's syndrome, influenza vaccination, and heart disease may be associated with FL incidence. Associations between FL and exposure to pesticides, industrial solvents, hair dyes, and alcohol/tobacco were inconsistent. Genetic risk factors include variants at the 6p21.32 region of the MHC II locus, polymorphisms of the DNA repair gene XRCC3, and UV exposure in individuals with certain polymorphisms of the vitamin D receptor. Increasing our understanding of risk factors for FL must involve integrating epidemiological studies of genetics and exposures to allow for the examination of risk factors and interactions between genes and environment.

    The identification of monotypic light chains is an important adjunct to the diagnosis of B-cell lymphoma, yet to reliably perform it on formalin-fixed paraffin sections is often difficult. We have evaluated a new set of monoclonal antibodies to kappa and lambda light chains that are reactive in paraffin sections. In reactive lymphoid tissues, polytypic staining was noted in greater than 95% of cases, with strong staining of plasma cells, moderate staining of the follicular dendritic cell network, and weak staining of mantle zone cells. Strong staining of the appropriate light chain was seen in each of the 7 cases of multiple myeloma. In a series of 58 cases of B-cell lymphoma, correlation between the results of immunohistochemistry and flow cytometry was obtained in 36 cases (62%), including 32 cases (21 kappa and 11 lambda) in which a single light chain was expressed. Monotypic staining was also seen in 6 additional cases (10%) in which flow cytometry was negative. Thirty of 46 cases (65%) of follicular lymphoma showed monotypic light chain expression, in contrast to 64 of 67 cases (95%) of reactive lymphoid hyperplasia, which showed polytypic light chain expression. These antibodies may provide an effective adjunct to the diagnosis of B-cell lymphoma in routine diagnostic work.

    Follicular lymphoma (FL) is an indolent disease but transforms in 2% to 3% of patients per year into aggressive, large cell lymphoma, a critical event in the course of the disease associated with increased lymphoma-related mortality. Early transformation cannot be accurately predicted at the time of FL diagnosis and the biology of transformed FL (TFL) is poorly understood. Here, we assembled a cohort of 126 diagnostic FL specimens including 40 patients experiencing transformation (transformation for at least 5 years. In addition, we assembled an overlapping cohort of 155 TFL patients, including 114 cases for which paired samples were available, and assessed temporal changes of routinely available biomarkers, outcome after transformation, as well as molecular subtypes of TFL. We report that the expression of IRF4 is an independent predictor of early transformation (Hazard ratio, 13.3; P transformation predicts favorable prognosis. Moreover, applying the Lymph2Cx digital gene expression assay for diffuse large B-cell lymphoma (DLBCL) cell-of-origin determination to 110 patients with DLBCL-like TFL, we demonstrate that TFL is of the germinal-center B-cell-like subtype in the majority of cases (80%) but that a significant proportion of cases is of the activated B-cell-like (ABC) subtype (16%). These latter cases are commonly negative for BCL2 translocation and arise preferentially from BCL2 translocation-negative and/or IRF4-expressing FLs. Our study demonstrates the existence of molecular heterogeneity in TFL as well as its relationship to the antecedent FL.

    A number of diseases and external factors can deplete limbal stem cells, causing pain and visual loss. Ten years have passed since the first transplantation of cultured oral mucosal epithelial cells in humans, representing the first autologous cell-based therapy for severe bilateral limbal stem cell deficiency. Its steady increase in popularity since then can be attributed to the accumulating evidence of its efficacy in reverting limbal stem cell deficiency. In this review, the focus is on clinical, and to a lesser degree laboratory, features of cultured oral mucosal epithelial transplants over the past 10 years. Comparisons with other available technologies are made. Avenues for research to stimulate further improvements in clinical results and allow worldwide distribution of limbal stem cell therapy based on oral mucosal cells are discussed. These include storage and transportation of cultured oral mucosal epithelial sheets and in vivo culture of oral mucosal epithelial cells.

    Full Text Available The distribution of healthy and atretic follicles on the ovarian surface of improved Valachian ewes 17, 24, and 32 days postpartum is reported in this study. The number of healthy follicles was higher on day 24 postpartum and their mean diameter tended to increase to day 32 (P<0.05 with the greatest diameter of 5 mm. 78–81% of atretic follicles ≥3 mm in diameter was observed where apoptosis began in the follicular cells situated at the follicular cavity. The early atretic follicles are characterized by the presence of mitotic pictures. In one ewe 24 days postpartum, small regressive follicular cysts were observed. Contracting atresia is characterized by thickening of the theca interna even to 190 μm. Progesterone and oestradiol-17β concentrations were maintained at relatively low levels, but with no significant difference between the days postpartum.

    Despite remaining an incurable disease, overall survival improvements have been noted in patients with advanced stage follicular lymphoma. The Follicular Lymphoma International Prognostic Index (FLIPI) is a robust prognostic index in this disease, and continues to provide prognostic information in the rituximab era. Rituximab has significantly changed the management of follicular lymphoma, and the most dramatic impact of rituximab is observed in combination with cytotoxic chemotherapy. However, resistance to rituximab remains a problem, and standard therapy in the rituximab-refractory setting includes radioimmunotherapy, autologous stem cell transplantation, and allogeneic stem cell transplantation. In addition, several novel agents show encouraging activity in FL, including bendamustine, lenalidomide, bortezomib and other proteasome inhibitors, and BCL2 inhibitors. PMID:18760706

    This study was designed to determine follicular atresia in the newborn and the prepubertal spiny mouse. We analyzed the processes of follicle loss using classical markers of apoptosis (TUNEL reaction, active caspase-3) and autophagy (Lamp1). Numerous small clear vacuoles and autophagosomes as well as strong Lamp1 staining were observed in dying oocytes of all follicle types, especially of the primordial and primary ones. Active caspase 3 and the TUNEL reaction were detected only in the granulosa cells of large secondary and antral follicles. The expression of apoptosis and autophagy markers was also changing during the prepubertal period. Western blot analysis indicated that at the moment of birth, females undergo an increased rate of follicular atresia mediated by autophagy, while apoptosis is the dominant form of ovarian atresia in consecutive postnatal days. On the basis of these observations, we concluded that apoptosis and autophagy are involved in follicular atresia and these processes are cell and developmental stage-specific.

    It has long been known that CD4 T cells are necessary to provide help to B cells, triggering a germinal centre (GC) reaction where affinity maturation and isotype switching occur. However, the nature of the dedicated CD4 helper T cells, known as T follicular helper (Tfh), was only recently described. Here, we review the biology and function of the recently described T follicular regulatory (Tfr) cells, another CD4 T-cell population also found within GCs but with regulatory function and characteristics. Tfr cells have been identified in mice and humans as simultaneously presenting characteristics of T follicular cells (namely CXCR5 expression) and regulatory T cells (including Foxp3 expression). These Tfr cells have been implicated in the regulation of the magnitude of the GC reaction, as well as in protection from immune-mediated pathology. © 2017 John Wiley & Sons Ltd.

    Objective To diagnose and treat multiple thoracic vertebral metastases of thyroid follicular carcinoma accompanied by vertebral instability. Methods On December 9th, 2013, a patient with multiple thoracic vertebral metastases of thyroid follicular carcinoma was adopted and treated, whose clinical data were analyzed. Results The patient was diagnosed as multiple thoracic vertebral metastases of thyroid follicular carcinoma by single-Photon Emission Computed Tomography ( SPECT ) and whole-body Magnetic Resonance Imaging ( MRI ). Due to the presence of vertebral instability, the risk of vertebral collapse or spinal cord injury existed. Open reduction and internal ifxation were performed under general anesthesia. Moreover, palliative care of tumors was temporarily carried out, and thoracic vertebral metastases were further treated after the operation. The general condition of the patient was good postoperatively. Additionally, the X-ray showed good position of the pedicle screw system. Reexamination was performed at 1 month after the operation. The spinal stability recovered, and the range of motion of the lumbar was not obviously limited. No complications such as incision infections, nerve injuries or deep venous thrombosis of lower limbs were noticed. The postoperative X-ray showed good position of the pedicle screw system and no lossening, bending or breakage of the internal ifxator. Conclusions For the patients with multiple thoracic vertebral metastases of thyroid follicular carcinoma accompanied by vertebral instability, surgical operation is an optimal option. With more secure and targeted therapy, satisfactory stability of the spine will be obtained.

    A 73-year-old man, in clinical remission 17 years after radiation therapy for a localized low-grade follicular lymphoma (FL), developed extensive lymphadenopathy, ascites, and splenomegaly with splenic masses. Axillary lymph node biopsy showed FL composed of nodules of centrocytes side by side with nodules of immunoblasts rather than centroblasts. Immunophenotyping revealed conventional FL markers (BCL-2, BCL-6, and CD10) as well as MUM-1 in the immunoblastic component, suggesting postgerminal center differentiation. Fluorescence in situ hybridization showed t(14;18) in both centrocytic and immunoblastic components and a copy gain of BCL-6 predominantly in the immunoblastic component. Areas of centrocytic and of immunoblastic nodules were macrodissected separately and underwent molecular evaluation for immunoglobulin heavy chain gene rearrangement. Identical base-pair peaks were found, attesting to their clonal identity. This case represents a very unusual example of transformation of a low-grade FL to a nodular immunoblastic FL.

    Background: Has a conscious exclusion of the contralateral major salivary glands (parotid, submandibular, and sublingual glands) a significant impact on the milieu of the oral cavity (saliva flow, pH, buffer capacity, and colonisation with Streptococcus mutans) in patients with ENT tumors receiving radical radiotherapy? Patients and Methods: 20 consecutive consentient patients with ENT tumors were evaluated once before, weekly during, and 6 weeks after the end of treatment in regard to saliva flow, pH, buffer capacity, and colonisation with Streptococcus mutans. In 13 patients the major salivary glands on both sides were included in the treated volume, in seven patients the treatment portals excluded consciously the contralateral major salivary glands. Results: The stimulated saliva flow decreases already during the 1st week of radiotherapy, the decrease follows the dose exponentially; the saliva flow is further reduced in the weeks after the end of treatment. The effect is less pronounced in patients with sparing of contralateral major salivary glands. The majority of patients with unilateral sparing of the major salivary glands retain the baseline value of buffer capacity, whereas buffer capacity of all patients with inclusion of all major salivary glands is markedly reduced with 20 Gy already, without signs of recovery when treatment has stopped. With unilateral salivary gland sparing the pH always remains basic, in bilaterally irradiated patients the pH changes from a mean of 7.3 to 5.8 during treatment. The colonisation with Streptococcus mutans varies little in both groups during the radiotherapy; after the end of therapy, it is higher in bilaterally irradiated patients. Conclusions: The conscious arrangement of irradiation portals in order to spare contralateral major salivary glands in patients with radical radiotherapy of ENT tumors has a significant influence on the oral environment: the stimulated saliva flow is higher, the buffer capacity retains the

    Pityriasis rubra pilaris is a chronic inflammatory dermatosis of unknown etiology and great clinical variability. It has been divided into six categories. Types III, IV, and V occur in childhood and are distinguished by their clinical presentation, age of onset, and course. We report a 19-year-old male patient with a 2-week history of pruritic, scaling dermatosis of the hands, feet, elbows, and knees. He had no family history of skin disease. On physical examination, we observed circumscribed, reddish-orange, scaling plaques affecting the elbows and knees and a waxy palmoplantar keratoderma. The skin biopsy showed acanthosis, alternating orthokeratosis, parakeratosis, and follicular plugging suggestive of pityriasis rubra pilaris. The patient started treatment with oral acitretin, 25 mg every other day. The treatment was tolerated well, and after 6 months the lesions had resolved completely. Pityriasis rubra pilaris is a chronic papulosquamous disorder of unknown pathogenesis, characterized by reddish-orange scaly plaques, palmoplantar keratoderma, and keratotic follicular papules. There is still no consensus regarding the treatment, but therapeutic options include systemic retinoids, particularly acitretin in the recommended dose of 0.5 to 0.75 mg/kg/day. In our case, the patient was treated with a low-dose regimen of acitretin, which was effective and well tolerated.

    Although there are many factors that affect postoperative serum levels of thyroglobulin (Tg), such levels have been previously used to detect recurrence of papillary and follicular thyroid carcinomas. This study was conducted to elucidate the significance of postoperative levels of Tg in patients with clinical presentations of papillary thyroid carcinoma, follicular thyroid carcinomas, or both. To collect data pertaining to patients with thyroid cancer who were treated in Chang Gung Medical Center in Linkou, Taiwan, records relating to a total of 847 patients with pathologically verified papillary or follicular thyroid cancer, all of whom received total thyroidectomy and thyroid remnant ablation with radioactive iodide ((131)I), were studied. To evaluate the clinical significance of postoperative levels of Tg, the patients were categorized into three groups based on postoperative Tg level. Group A was classified as those demonstrating a 1-month postoperative Tg levels less than 1 ng/ml. Group B patients were classified as those displaying a 1-month postoperative Tg levels greater than or equal to 1 ng/ml, but less than 10 ng/ml. Group C patients were classified as those exhibiting a 1-month postoperative Tg levels great than or equal to 10 ng/ml. Of the patients in group A, none presented with distant metastases at the time of diagnosis or during the follow-up period. In group B, 15 patients (3.5%) died of thyroid cancer. In this group, tumor size was an important factor in cancer-related mortality, diagnostic clinical class, and follow-up status. Of the 491 patients in group C, 49 (10.0%) patients died of thyroid cancer. Among the patients in group C, age, histopathologic type, stage of diagnosis, and follow-up Tg values were important factors. Among groups A, B, and C, there were 161 (95.8%), 253 (76.4%), and 129 (37.1%) patients, respectively, with disease-free status at the end of 1998. Postoperative serum Tg levels can be used as a prognostic indicator in

    Diagnosis of thyroid by fine needle aspiration is challenging for the "indeterminate" category and can be supported by molecular testing. We set out to identify miRNA markers that could be used in a diagnostic setting to improve the discrimination of mutation-negative indeterminate fine needle...... aspirations. miRNA high-throughput sequencing was performed for freshly frozen tissue samples of 19 RAS and PAX8/PPARG mutation-negative follicular thyroid carcinomas, and 23 RAS and PAX8/PPARG mutation-negative follicular adenomas. Differentially expressed miRNAs were validated by quantitative polymerase...... chain reaction in a set of 44 fine needle aspiration samples representing 24 follicular thyroid carcinomas and 20 follicular adenomas. Twenty-six miRNAs characterized by a significant differential expression between follicular thyroid carcinomas and follicular adenomas were identified. Nevertheless...

  10. Advances in hair transplantation: longitudinal partial follicular unit transplantation.

    Science.gov (United States)

    Gho, Coen G; Neumann, H A Martino

    2015-01-01

    There are different techniques of hair transplantation. The most common and known hair transplantation methods are the 'strip' method, where a strip of skin containing hair follicles is removed, cut into grafts and implanted in the recipient area, and the follicle unit extraction (FUE) method, in which whole follicle units are extracted one by one and implanted one by one back into the recipient area. The FUE method is more patient friendly and leaves only tiny scars compared to the strip method, which leaves visible linear scars at the donor area. Both methods, however, have the major disadvantage that the extracted hair follicles are removed and the availability of donor hair follicles are limited and results in a decrease in hair density, as no re-grow will occur in the donor area. Since partial longitudinal-follicular unit transplantation (PL-FUT) extracts partial longitudinal follicular units that can be used as complete follicular units to regenerate completely differentiated hair growth and the partial follicular units that remain in the dermis in the donor area can survive and produce hair, PL-FUT enables us to multiply hair follicles in vivo while preserving the donor area. Although this technique is suitable for androgenic alopecia, PL-FUT could also be suitable in persons who have a relative small donor area compared to the recipient area like burn victims, as well as scarring alopecia's like frontal fibrosing alopecia.

    In the past, it was assumed that the intercellular route was the only relevant penetration pathway for topically applied substances. Recent results on follicular penetration emphasize that the hair follicles represent a highly relevant and efficient penetration pathway and reservoir for topically applied substances. This study investigates a selective closure technique of hair follicle orifices in vivo assessing interfollicular and follicular absorption rates of topical minoxidil foam in humans. In delimited skin area, single hair orifices or interfollicular skin were blocked with a microdrop of special varnish-wax-mixture in vivo. Minoxidil foam (5%) was topically applied, and transcutaneous absorption was measured by a new surface ionization mass spectrometry technique in serum. Different settings (open, closed or none of both) enabled to clearly distinguish between interfollicular and follicular penetration of the topically applied minoxidil foam. Five minutes after topical application, minoxidil was detected in blood samples when follicles remained open, whereas with closed follicles 30 min were needed. Highest levels were found first when both pathways were open, followed by open follicles and subsequently by closed follicles. These results demonstrate the high importance of the follicular penetration pathway. Hair follicles are surrounded by a dense network of blood capillaries and dendritic cells and have stem cells in their immediate vicinity, making them ideal targets for drug delivery.

    Long-acting medications have been developed and approved for use in the treatment of attention-deficit hyperactivity disorder (ADHD). These compounds are intended to optimize and maintain symptoms control throughout the day. We tested prolonged effects of osmotic-release oral system methylphenidate on both attention and inhibition, in the late afternoon. A double-blind, randomized, placebo-controlled study was conducted in 36 boys (7-12 years) with ADHD and 40 typically developing children. The ADHD children received an individualized dose of placebo or osmotic-release oral system methylphenidate. They were tested about 8 hours after taking with 2 continuous performance tests (continuous performance test-X [CPT-X] and continuous performance test-AX [CPT-AX]) and a counting Stroop. A positive effect of osmotic-release oral system methylphenidate was present in CPT-AX with faster and less variable reaction times under osmotic-release oral system methylphenidate than under placebo, and no difference with typically developing children. In the counting Stroop, we found a decreased interference with osmotic-release oral system methylphenidate but no difference between children with ADHD under placebo and typically developing children. © The Author(s) 2014.

  16. Metformin regulates ovarian angiogenesis and follicular development in a female polycystic ovary syndrome rat model.

    Polycystic ovary syndrome (PCOS) is a frequent pathology that affects more than 5% of women of reproductive age. Among other heterogeneous symptoms, PCOS is characterized by abnormalities in angiogenesis. Metformin has been introduced in the treatment of PCOS to manage insulin resistance and hyperglycemia. Besides its metabolic effects, metformin has been shown to improve ovulation, pregnancy and live birth rates in PCOS patients. In the present study, we used a dehydroepiandrosterone-induced PCOS rat model to analyze the effect of metformin administration on ovarian angiogenesis. We found that metformin was able to restore the increased levels of vascular endothelial growth factor, angiopoietin (ANGPT)1, and ANGPT1/ANGPT2 ratio and the decreased levels of platelet-derived growth factor B and platelet-derived growth factor D observed in the dehydroepiandrosterone-treated rats. These effects could take place, at least in part, through a decrease in the levels of serum insulin. We also found an improvement in follicular development, with a lower percentage of small follicles and cysts and a higher percentage of antral follicles and corpora lutea after metformin administration. The improvement in ovarian angiogenesis is likely to restore the accumulation of small follicles observed in PCOS rats and to reduce cyst formation, thus improving follicular development and the percentage of corpora lutea. These results open new insights into the study of metformin action not only in glucose metabolism but also in ovarian dysfunction in PCOS women.

    The article is based on the treatment results of 44 patients with follicular tunor of thyroid gland. A staged morphological assessment of thyroid nodes was performed for all patients: in case of preoperative fine-needle biopsy, urgent intraoperative study and according to results of final histological research. The urgent histological study of surgical material was conducted for 44 patients with diagnosis "follicular tumor" according to fine-needle biopsy. The data of final histological study were matched with findings of intraoperative research. A micro-follicular adenoma was detected in 22 patients (50%) and 6 (13,6%) patients had this diagnosis combined with autoimmune thyroiditis. The general part of patients didn't changed in final study, but the rate of diagnosis "micro-follicular adenoma against the background of autoimmune thyroiditis" increased. Papillary carcinoma was revealed in 5 (11,4%) patients and follicular cancer had 4 (9,1%) patients detected in intraoperative study and 3 (6,8%) more patients according to data of final research. The histopathologic feature of colloid goiter was observed in 7 (15,9%) cases and a part of such patients reduced to 6,8% during final study. One of the patients (2,3%) had final diagnosis "oncocytoma". In case of thyroid nodules detection the needle biopsy should be carried out regardless to the size of nodule. The authors recommended performing the surgery with the urgent histological study in case of undetermined histological report. The following surgical strategy was specified by the results of the urgent histological report.

    There is much interest in the possible ameliorating effects of estrogen on various autoimmune diseases. We previously established the protective effects of 17 beta-estradiol (E2) on experimental autoimmune encephalomyelitis (EAE). In the current study we investigated the effectiveness of oral treatment with ethinyl estradiol (EE) on EAE and the mechanisms involved. Ethinyl estradiol is a semisynthetic estrogen compound found in birth control pills, and its chemical structure allows this compound to retain activity when given orally. We found that oral EE, like E2, drastically suppressed EAE induced by proteolipid protein 139-151 peptide when given at initiation of EAE. However, unlike E2, EE reduced clinical severity when given after the onset of clinical signs. Treatment with EE significantly decreased the secretion of proinflammatory cytokines (IFN-gamma, TNF-alpha, and IL-6) by activated T cells as well as the expression of a key matrix metalloproteinase, disease-mediating chemokines/receptors, and IgG2a levels, but increased the expression of TGF-beta 3 in the CNS. The absence of infiltrating lymphocytes together with the suppression of cytokines, matrix metalloproteinase, and chemokines/receptors suggests that EE, like E2, protects mice from EAE by inhibiting the recruitment of T cells and macrophages into the CNS. These results suggest that oral ethinyl estradiol might be a successful candidate as therapy for multiple sclerosis.

    Full Text Available Desmoplastic ameloblastoma (DA is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined corticated border, whereas computed tomography revealed a unilocular radiolucent lesion and buccal expansion together with cortical perforation. The lesion was treated via enucleation and curettage of the marginal bone and fenestration. A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes. The patient’s postoperative course has been favorable up to now, and no marked changes have been observed. We presented a case of hybrid ameloblastoma and reviewed the 36 reported cases of hybrid ameloblastoma that have been reported in the English literature.

    Differentiated thyroid carcinoma of follicular origin (DTCFO), although not very frequent, has registered a raising incidence in the last decades. In the majority of the cases, DTCFO is a curable disease when treated and monitored by experienced, multidisciplinary teams. These factors contribute to an increasing number of DTCFO survivors requiring life-long monitoring, due to the possibility of occurrence of recurrences many years after the initial treatment. Several aspects of the treatment and management of these patients are still controversial. The present protocol represents the consensus of the members of the Grupo de Estudo da Tiróide of the Sociedade Portuguesa de Endocrinologia, Diabetes e Metabolismo. It aims to define guidelines, in agreement with the current state of the art and contemplating the necessary adaptations to local constrains, that ensure decreased mortality and protection of patients' quality of life, avoiding unnecessarily aggressive or ineffective treatments, optimizing the use of the available resources.

    An 11-year-old, spayed female domestic shorthair cat was presented for a right flank wound. On clinical examination, a single non-painful skin tear lesion with irregular edges was detected. During the examination, star-shaped cigarette paper-like skin lesions appeared spontaneously. An abdominal mass was also palpated. Feline skin fragility syndrome (FSFS) was suspected and a multicentric lymphoma was diagnosed by fine needle aspiration. The cat's condition declined and it died spontaneously. Post-mortem examination confirmed the diagnosis of lymphoma. Neoplastic lymphocytes were not observed in the skin. Histological analysis of the skin was consistent with the morphological aspects of FSFS. A possible direct link between the two conditions remains a matter of speculation, but this case report provides the first description of FSFS associated with multicentric follicular lymphoma. Thus, multicentric follicular lymphoma should be considered as a differential diagnosis in cats presenting with FSFS.

    Follicular lymphoma is essentially a disease of the elderly, and the aging of the population in developed countries will increase patient numbers in coming years. Significant achievements have been made for treatment, but better understanding of the disease and major progress in biology now facilitate the development of many new drugs, which may have improved toxicity profiles making them appropriate for treatment of older adults. However, the increasing number of treatment possibilities, can also increase the toxicity risks, and unexpected toxicities specific to older adults may be encountered. Consequently, specific studies of older patients should be considered, using appropriate evaluation tools such as comprehensive geriatric assessment. This review will described the development of these new drugs, in the context of the treatment of older-adults with follicular lymphoma.

    @@ Follicular dendritic cell (FDC) is an essential component of the nonlymphoid, nonphagocytic immunoaccessory reticulum cells of the peripheral lymphoid tissue.1 Follicular dendritic cell sarcoma (FDCs) are confined largely to the primary and secondary B-cell follicles, where they form a tight interlacing meshwork. They play a role in the capture and presentation of antigens, generation and regulation of immune complexes. FDCs can be recognized morphologically by their indistinct cellular borders, pale eosinophilic cytoplasm, round-to-ovoid nuclei with delicate nuclear membranes and clear-to-vesicular chromatin with inconspicuous or small nucleoli. FDCs are best identified through immunostaining using CD21, CD35, R4/23, KiM4, KiM4p and Ki-FDC1p.

    Full Text Available Effect of stress on pre-pubertal ovarian follicular development was studied. Fifteen day old female rats were administered under stress (exposed to maternal separation; 6 hours/day from post-natal day 15 to 21 for 7 days, and appropriate controls were maintained. The time of exposure was randomly changed every day during light phase (7AM to 7 PM of the day to avoid habituation. There was a significant decrease in serum estrogen levels on post-natal day 21 in stress group rats compared to controls indicating stress response in these rats. However, mean number of healthy follicles in all categories of follicles were significantly lower in stressed rats compared to controls. Concomitant with these changes, mean number of atreitic follicles showed an increase over control values in stressed rats. In contrast administration of Naltrexone (5μg NTX/rat/day, Mifepristone (1 μg MP/rat/day, FSH (10 IU FSH/rat/day with stressed the significant increases in the relative weight of ovary, uterus, fallopian tube, body weight and the mean number of healthy follicles in the ovary compared to the controls. In the ovary treatment of stressed did not affect primordial follicles. Primordial follicles were reduced in number significantly in the ovary of controls and treated groups when compared with the initial controls whereas there was no significant variation among the controls and the treated groups. The results indicate that stress dose not interfere with the progress of pre-pubertal follicular development. However, it causes increased loss of follicles by atretia.

    B lymphocytes differentiate into antibody-secreting cells under the antigen-specific control of follicular helper T (TFH) cells. Here, we demonstrate that isotype-switched plasma cells expressed MHCII, CD80 and CD86 and intracellular machinery required for antigen presentation. Antigen-specific plasma cells could access, process and present sufficient antigen in vivo to induce multiple TH cell functions. Importantly, antigen-primed plasma cells failed to induce interleukin 21 or Bcl-6 in naïv...

    Full Text Available Background: In hair transplantation, the survival rate of harvested grafts depends upon many factors like maintenance of hydration, cold temperature, reduced mechanical handling and asepsis. All these factors are favourably improved if time out of body is reduced significantly. We have tried a modification called direct hair transplantation in the existing follicular unit extraction technique, in which the follicular unit grafts are implanted as soon as they are harvested. In this article, we have described the detailed methodology and a series of 29 patients who underwent direct hair transplantation. Aim: To evaluate the efficacy and feasibility of direct hair transplantation. Subjects and Methods: The patients willing to undergo hair transplantation by the technique of follicular unit extraction were enrolled for the surgery. After administration of local anaesthesia, the recipient sites were created. Thereafter, the processes of scoring the skin with a motorized punch, graft extraction and implantation were performed simultaneously. These patients were followed up to look for the time period of initiation of hair growth, the growth achieved at the end of 6-8 months and any adverse events. The results of patients with noticeable improvement in the photographs and reduction in baldness grade were taken as ′good′, whereas, in other patients, it was classified as ′poor′. Results: All patients were males with age ranging from 21 to 66 years (median 30 years. Twenty-six patients had androgenetic alopecia, 1 patient had traction alopecia and 2 patients had scarring alopecia. Twenty-seven patients showed ′good′ results, whereas 2 patients showed ′poor′ results. Conclusion: Direct hair transplantation is a simple and feasible modification in the follicular unit extraction technique. It is an efficacious surgical treatment modality for baldness.

Oral myiasis is a rare condition associated with poor oral hygiene, mental disability, halitosis and other conditions. We present a case report of an adult mentally challenged woman with extensive necrotic oral lesion burrowing into the hard palate through which three live maggots (larvae were seen emerging out. The larvae were removed using forceps and the patient was treated with oral ivermectin. The maggots were identified as larvae of the Chrysomya bezziana fly.

  15. Nutritional and lactational effects on follicular development in the pig.

    Science.gov (United States)

    Quesnel, H

    2009-01-01

    In sows, follicular development is inhibited during lactation, and weaning the piglets allows recruitment and selection of follicles that will undergo preovulatory maturation and ovulate. Lactation inhibits GnRH secretion, and in turn LH secretion, through neuroendocrine stimuli induced by suckling. Pituitary response to GnRH and the sensitivity of the hypothalamo-pituitary unit to oestradiol positive feedback are also reduced. The impact of lactation on the reproductive axis is further complicated by the physiological and metabolic adaptations that are developed for milk production and that depend on nutrient intake, nutrient needs and body reserves. A strongly catabolic state during lactation amplifies the inhibition of LH secretion, thereby inducing a delay of oestrus and ovulation after weaning. Nevertheless, post-weaning ovulation is less delayed nowadays than in the 1970's or 80's. Nutritional deficiency has also deleterious effects on embryo survival, which are likely related to alterations in follicular growth and maturation. The physiological mechanisms by which information on the metabolic changes is transmitted to the hypothalamus-pituitary-ovary axis are not fully understood in the sow. Glucose, insulin and leptin are the most likely signals informing the hypothalamus of the metabolic state, yet their roles have not been definitely established. At the ovarian level, folliculogenesis is likely to be altered by the reduction in insulin and IGF-I concentrations induced by nutritional deficiency. More knowledge is needed at the intrafollicular level to better understand nutritional effects on follicular development, and also on occyte quality and embryo development.

    2011-11-23

    The discovery that Bcl-6 was the transcriptional regulator of follicular helper T (Tfh) cells completed the recognition of this population as an effector subset specialized in the provision of help to B cells. Improved reagents and recent models that allow tracking of Bcl-6-expressing T cells have revealed that the decision to become a Tfh cell occurs soon after T cells are primed by dendritic cells and start dividing, before interaction with B cells. The latter are important for sustaining Bcl-6 expression. Bcl-6 coordinates a signaling program that changes expression or function of multiple guidance receptors, leading to Tfh cell localization within germinal centers. This program is not unique to CD4(+) helper T cells; FoxP3(+) regulatory T cells and NKT cells co-opt the follicular differentiation pathway to enter the follicle and become specialized follicular cells. This review will focus on recent insights into the early events that determine Tfh cell differentiation. Copyright © 2011 Elsevier Inc. All rights reserved.

    Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

    Reported post-surgery 1-year survival rate for oral canine malignant melanoma (cMM) is around 30%; novel treatments are needed as the role of adjuvant chemotherapy is unclear. This prospective study regards adjuvant electrovaccination with human chondroitin sulfate proteoglycan-4 (hCSPG4)-encoded plasmid in 23 dogs with resected II/III-staged CSPG4-positive oral cMM compared with 19 dogs with resected only II/III-staged CSPG4-positive oral cMM. Vaccination resulted in 6-, 12-, 18- and 24-month survival rate of 95.6, 73.9, 47.8 and 30.4%, respectively [median survival time (MST) 684 days, range 78-1694, 8 of 23 dogs alive] and 6-, 12-, 18- and 24-month disease-free interval (DFI) rate of 82.6, 47.8, 26.1 and 17.4%, respectively (DFI 477 days, range 50-1694). Non-vaccinated dogs showed 6-, 12-, 18- and 24-month survival rate of 63.2, 26.3, 15.8 and 5.3%, respectively (MST 200 days, range 75-1507, 1 of 19 dogs alive) and 6-, 12-, 18- and 24-month DFI rate of 52.6, 26.3, 10.5 and 5.3%, respectively (DFI 180 days, range 38-1250). Overall survival and DFI of vaccinated dogs was longer in those <20 kg. In vaccinated and non-vaccinated dogs local recurrence rate was 34.8 and 42%, respectively while lung metastatic rate was 39 and 79%, respectively.

    Terconazole is a new, broad-spectrum, triazole antifungal agent. The aim of this study was to compare the efficacy and safety of a 6-day course of a terconazole vaginal suppository (80 mg) with two doses of oral fluconazole (150 mg) for the treatment of severe vulvovaginal candidiasis (SVVC). In this prospective, randomized case-control study, 140 consecutive patients with SVVC were enrolled at the Department of Obstetrics and Gynecology of Peking University Shenzhen Hospital from July 1, 2013, through June 31, 2014. Patients with SVVC, initially at a 1:1 ratio, were randomly assigned to receive treatment with either the terconazole vaginal suppository or oral fluconazole. The patients had follow-up visits at 7-14 days and 30-35 days following the last dose of therapy. The clinical cure rates in the terconazole group and the fluconazole group were, respectively, 81.0% (47/58) and 75.8% (50/66) at follow-up day 7-14 and 60.3% (35/58) and 56.1% (37/66) at day 30-35. The mycological cure rates in the two groups were, respectively, 79.3% (46/58) and 71.2% (47/66) at follow-up day 7-14 and 62.1% (36/58) and 53.0% (35/66) at day 30-35 (P > .05 for all). Local irritation was the primary adverse event associated with terconazole, whereas systemic side effects were associated with fluconazole; however, these effects were minimal. This study demonstrated that a terconazole vaginal suppository (80 mg daily for 6 days) was as effective as two dose of oral fluconazole (150 mg) in the treatment of patients with SVVC; as such, terconazole could be a choice for therapy of this disorder. © The Author 2015.

    Rho-associated kinase 2 (ROCK2) determines the balance between human T helper 17 (TH17) cells and regulatory T (Treg) cells. We investigated its role in the generation of T follicular helper (TFH) cellswhich provide help necessary to generate antibody-producing B cells in normal and autoimmune conditionsWe found that targeting ROCK2 in normal human T cells or peripheral blood mononuclear cells (PBMCs) from patients with active systemic lupus erythematosus (SLE) decreased the number and function of Tfh cells induced by activation ex vivo. Moreover, inhibition of ROCK2 activity concomitantly decreased the abundance of the transcriptional regulator Bcl6 and increased that of Blimp1 by xxx concurrent regulation of the binding of signal transducer and activator of transcription 3 (STAT3) and STAT5 to the promoters of the genes Bcl6 and PRDM1, respectively. In the MRL/lpr murine model of SLE, oral administration of the selective ROCK2 inhibitor KD025 resulted in a two-fold reduction in the numbers of Tfh cells and antibody-producing plasma cells in the spleen, as well as a decrease in the size of splenic germinal centers, sites of interaction between TFH cells and B cells. KD025-treated mice showed a substantial improvement in both histological and clinical scores compared to those of untreated mice, and had reduced amounts of Bcl6 and phosphorylated STAT3, as well as increased STAT5 phosphorylation. Together, these data suggest that ROCK2 signaling plays a critical role in controlling the development of Tfh cells induced by autoimmune conditions through reciprocal regulation of STAT3 and STAT5 activation.

    Full Text Available Abstract Background Glutamine (Gln supplementation during concurrent chemoradiotherapy (C-CRT effectively reduces the incidence and severity of acute radiation-induced esophagitis (RIE. However, there are concerns that Gln might stimulate tumor growth, and therefore negatively impact the outcomes of anticancer treatment. We retrospectively investigated the effect of co-administration of oral Gln during C-CRT on survival outcomes of patients with stage IIIB non-small cell lung carcinoma (NSCLC. We additionally evaluated role of oral Gln in preventing C-CRT-induced weight change, acute and late toxicities. Methods The study included 104 patients: 56 (53.8% received prophylactic powdered Gln (Gln+ orally at a dose of 10 g/8 h and 48 (46.2% did not receive Gln (Gln- and served as controls. The prescribed radiation dose to the planning target volume was 66 Gy in 2-Gy fractions. Primary endpoints of progression-free survival (PFS, local/regional progression-free survival (LRPFS, and overall survival (OS were correlated with status of Gln supplementation. Results Oral Gln was well tolerated except for mild nausea/vomiting in 14 (25.0% patients. There was no C-CRT-related acute or late grade 4–5 toxicity. Administration of Gln was associated with a decrease in the incidence of grade 3 acute radiation-induced esophagitis (RIE (7.2% vs. 16.7% for Gln+ vs. Gln-; p=0.02 and late-RIE (0% vs. 6.3%; p=0.06, a reduced need for unplanned treatment breaks (7.1% vs. 20.8%; p=0.04, and reduced incidence of weight loss (44.6% vs. 72.9%; p=0.002.

    Full Text Available Patients receiving radiotherapy or chemotherapy will receive some degree of oral mucositis The incidence of oral mucositis was especially high in patients: (i With primary tumors in the oral cavity, oropharynx, or nasopharynx; (ii who also received concomitant chemotherapy; (iii who received a total dose over 5,000 cGy; and (iv who were treated with altered fractionation radiation schedules. Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene

    Accumulating evidences indicate that the cellular and molecular microenvironment of follicular lymphoma (FL) plays a key role in both lymphomagenesis and patient outcome. Malignant FL B cells are found admixed to specific stromal and immune cell subsets, in particular CD4pos T cells displaying phenotypic features of follicular helper T cells (TFH). The goal of our study was to functionally characterize intratumoral CD4pos T cells. We showed that CXCR5hiICOShiCD4pos T cells sorted from FL biopsies comprise at least two separate cell populations with distinct genetic and functional features: i) CD25pos follicular regulatory T cells (TFR), and ii) CD25neg TFH displaying a FL-B cell supportive activity without regulatory functions. Furthermore, despite their strong similarities with tonsil-derived TFH, purified FL-derived TFH displayed a specific gene expression profile including an overexpression of several genes potentially involved directly or indirectly in lymphomagenesis, in particular TNF, LTA, IL4, or CD40LG. Interestingly, we further demonstrated that these two last signals efficiently rescued malignant B cells from spontaneous and Rituximab-induced apoptosis. Altogether, our study demonstrates that tumor-infiltrating CD4pos T cells are more heterogeneous than previously presumed, and underlines for the first time the crucial role of TFH in the complex set of cellular interactions within FL microenvironment.

    It is now generally accepted that the human body exists in close synergy with the gut microbiome and that this cross-talk plays an essential role in human health and disease. One facet from the many interactions between the microbiome and the immune system is the induction of natural antibodies to commensal bacterial glycans, such as blood group antigens, the alpha-Gal epitope or the Thomsen-Friedenreich (TFα) antigen. Since we have observed that certain species of the commensal genus Bacteroides express the TFα antigen, we examined whether the oral dietary supplementation of a pasteurised Bacteroides xylanisolvens strain might be able to enhance the level of natural anti-TFα antibodies in healthy adults. The data obtained from a double-blind, placebo-controlled study involving 140 healthy volunteers and lasting 8 weeks revealed that the oral uptake of this strain was indeed able to increase the level of TFα-specific immunoglobulin M serum antibodies. The effect was dose-dependent but remained - at any doses - within the physiological range determined before intervention. Furthermore, the effect reverted after stopping the intake. The results support the idea of the microbiome inducing the generation of systemic antigen-specific antibodies against sugar epitopes. They also demonstrate the possibility to modulate essential regulatory or defence processes through dietary supplementation of selected commensal bacteria with the aim to assist human health.

    The objective of this study was to assess the impact of low-level laser therapy on wound swelling, wound temperature changes, and oral health-related quality of life (OHRQoL) after surgical removal of impacted lower third molars. Forty patients with impacted lower third molars requiring surgical removal participated in this study; all were Pell-Gregory class IIB or IIC. The patients were divided randomly into two groups for post-extraction therapy. One group received antimicrobial photodynamic therapy (aPDT) and the other received no additional therapy (placebo group). Temperature measurements were done using an infrared thermographic camera on days 3 and 7 postoperative. OHRQoL was assessed in both groups on day 7 using the Oral Health Impact Profile questionnaire translated into Croatian (OHIP-14-CRO). Prior to surgical treatment, there was no difference in patient characteristics between the two groups. A significantly lower temperature and less wound swelling were recorded on day 3 postoperative in the aPDT group compared to the control group (Plower OHIP-14-CRO summary scores (P<0.01). The present study showed beneficial effects of the aPDT modality of low-level laser therapy: postoperative wound swelling was reduced and wound temperature decreased, and OHRQoL was better through the 7-day postoperative period in comparison to the placebo group.

    Full Text Available Follicular thyroid carcinoma classically accounts for 10–32% of thyroid malignancies. We determined the incidence and the behaviour of follicular thyroid carcinoma in an endemic goitre area. A comparative analysis between minimally invasive and widely invasive follicular thyroid carcinoma was performed. The medical records of all patients who underwent thyroidectomy from October 1998 to April 2012 for thyroid malignancies were reviewed. Those who had a histological diagnosis of follicular carcinoma were included. Among 5203 patients, 130 (2.5% were included. Distant metastases at presentation were observed in four patients. Sixty-six patients had a minimally invasive follicular carcinoma and 64 a widely invasive follicular carcinoma. In 63 patients an oxyphilic variant was registered. Minimally/widely invasive ratio was 41/26 for usual follicular carcinoma and 25/38 for oxyphilic variant (P<0.05. Patients with widely invasive tumors had larger tumors (P<0.001 and more frequently oxyphilic variant (P<0.05 than those with minimally invasive tumours. No significant difference was found between widely invasive and minimally invasive tumors and between usual follicular carcinoma and oxyphilic variant regarding the recurrence rate (P=NS. The incidence of follicular thyroid carcinoma is much lower than classically retained. Aggressive treatment, including total thyroidectomy and radioiodine ablation, should be proposed to all patients.

    Cystic ovarian disease (COD) is a major factor contributing to poor reproductive efficiency of lactating dairy cows. The objective of the present study was to analyze the endocrine profile, growth dynamics, and histologic characteristics of persistent ovarian follicles-cysts developing in response to long-term administration of intermediate levels of progesterone. To this end, after synchronization of cows, a low dose of progesterone was administered for 5, 10, and 15 days after the expected day of ovulation in treated cows (groups P5, P10, and P15, respectively), using an intravaginal progesterone-releasing device. A significant increase in diameter was detected on Day 11 of progesterone treatment and thereafter (P Day 15 of persistence, the diameter of the persistent follicle reached a mean of 23 ± 0.6 mm. Microscopically, the persistent follicles had a complete granulosa, an intensely vascularized theca interna, and a collagenous theca externa layer. Temporal changes in the serum concentrations of estradiol, progesterone, and FSH were detected (effects of time, P days of persistence and declined (P days of persistence. The LH pulse concentration and pulse amplitude had a significant reduction (P Day 10 of follicular persistence (P Day 5 of follicular persistence, 17-hydroxyprogesterone showed a significant decrease at 5 days of follicular persistence in relation to proestrus, and testosterone showed a significant increase (P Day 5 of persistence through Day 15 of follicular persistence. Correlation between serum and follicular fluid steroid concentrations was significant for testosterone (P < 0.0001) and not significant for estradiol and progesterone. These findings indicate that ovarian cysts in COD are similar in many ways to the persistent follicles induced by progesterone, with an analogous hormonal and morphologic context, thus confirming a local role of subluteal levels of progesterone in COD pathogenesis and in the regulatory mechanisms of the ovarian

    The effect of propylene glycol drenching on ovarian and hormonal dynamics was studied in heifers. Five cycling heifers were used twice (as control and treatment) with crossover design. After the confirmation of ovulation (day 0), the heifers in the treatment group received propylene glycol on days 6, 7 and 8 as an oral drench (250 ml of 90% propylene glycol). On day 10, prostaglandin F2α (PGF2α), 15 mg per head of dinoprost, was administered intramuscularly to induce luteal regression followed by the follicular phase and then propylene glycol was again administered twice daily (500 ml/day) on days 10, 11 and 12. Palpation per rectum and ovarian ultrasonography were performed every other day from days 0 to 10, and daily after PGF2α administration until the subsequent ovulation (second ovulation) for analysis of follicular and luteal dynamics. Blood samples were also collected every other day from days 0 to 10, and then at 6 h intervals after PGF2α administration until the second ovulation. For the samples taken at 6-h intervals after PGF2α administration, the concentrations of glucose showed clear daily fluctuations in both groups. Changes in the plasma concentration of glucose in the treatment group were significantly (P propylene glycol drenching in heifers. However, no significant changes in ovarian and hormonal dynamics were found under such metabolic conditions.

    The 2016 annual meeting of the American Society of Hematology took place in San Diego, California, 3–6 December. At the meeting, results from key studies on the first-line treatment of follicular lymphoma were presented. Of those studies, key oral presentations included two analyzing data from the gallium study, which evaluated the efficacy and safety of obinutuzumab plus chemotherapy (G-chemo) compared with rituximab plus chemotherapy (R-chemo), followed, in responding patients with follicular lymphoma, by obinutuzumab or rituximab maintenance; results from the sabrina study, which evaluated the efficacy and safety of subcutaneous compared with intravenous rituximab; results of a cost-effectiveness analysis of first-line treatment with bendamustine and rituximab from a Canadian perspective; and results from the SAKK 35/10 study, which evaluated the safety and efficacy of rituximab plus lenalidomide compared with rituximab monotherapy. Our meeting report describes the foregoing studies and includes interviews with the Canadian investigators, plus commentaries by those investigators about the potential impact on Canadian practice.

Although the majority of patients in need of treatment derive significant benefit from conventional chemotherapeutic agents as well as monoclonal antibodies, less toxic and more effective treatments are needed. Novel agents that inhibit the B-cell receptor signaling pathway have shown promising outcomes in these disorders. Idelalisib is a potent selective oral inhibitor of phosphatidylinositol 3-kinase delta and has shown significant clinical activity in B-cell malignancies. In this review, we summarize the clinical trial data using idelalisib as monotherapy or in combination with rituximab for the treatment of relapsed/refractory disease. The adverse effect profile includes autoimmune disorders such as transaminitis, colitis, and pneumonitis. Given the efficacy and manageable toxicity profile of idelalisib, it is being increasingly incorporated into the management of indolent B-cell malignancies.

    To determine the efficiency of the developed expert system based on a set of qualitative signs of cell atypia and their weighting coefficients in the differential diagnosis of follicular cancer and follicular adenoma of the thyroid gland. Sixty cytologic preparations of patients with histologic diagnosis of a follicular cancer and follicular adenoma were investigated. Weighting coefficients for each sign of atypia for both forms of pathology have been calculated with the help of the deduced equation. This allowed creating an expert system by which the function of transforming qualitative signs of cell atypia to a quantitative form was realized. "Strength reserve" according to the diagnostic index value, coincidence of the verified diagnosis with the histologic conclusion, and its invariability for all 12 iterations testified to the reliability of an expert system. Preliminary trials showed the efficiency of an expert system for differentiating the nature of a thyroid follicular tumor to be 97.5%. The developed expert system allows high efficiency in making a differential diagnosis of thyroid follicular cancer and follicular adenoma.

    A 5-year-old, female neutered, Australian Kelpie presented with a 2-month history of dramatic bilateral erythematous thickening of the third eyelids. Ophthalmic examination demonstrated raised, pink to red, irregular thickening of the entire palpebral surface of both third eyelids. There were no other ocular abnormalities. A surgical biopsy was taken from each third eyelid. Histopathologic examination revealed sheets of macrophages, plasma cells, lymphocytes, and occasional fibroblasts and neutrophils infiltrating the third eyelid stroma. A diagnosis of chronic granulomatous conjunctivitis was made. Grossly and histopathologically this case closely resembles previously described cases of nodular granulomatous conjunctivitis involving the third eyelids of Collie dogs. This report describes an unusual case of nodular granulomatous conjunctivitis isolated to the third eyelids in an Australian Kelpie. Resolution of the condition was achieved with a combination of oral doxycycline, niacinamide and prednisolone.

    For the last 15 years, infection from Helicobacter pylori (H. pylori) has been recognized in gastritis pathogenesis, and is known to trigger an important inflammatory response in these patients. To determine the association between follicular gastritis and H. pylori infection in children seen at a public hospital in Peru. An analytic, cross-sectional study was conducted on all the children treated at the Hospital Nacional Docente Madre "Niño San Bartolomé" in Lima, Peru, within the time frame of 2011-2012. All the personal data from the patients' medical histories and endoscopic procedures were collected. The crude prevalence ratios (PR) were obtained and adjusted (aPR) with their 95% confidence intervals (95%CI), using generalized linear models with the binomial family and log link function. A total of 123 children met the study criteria. Forty-eight (39%) of the study sample were girls and the mean age of the children was 12 years. H. pylori was present in 44% of the sample and 9% presented with more than 100 bacteria per field (classified as +++). Thirty-five percent of the children had esophagitis due to concomitant reflux. The presence of H. pylori was associated with follicular gastritis (Pgastritis had a greater likelihood of having H. pylori than those that did not present with gastritis. These results can be extrapolated to other similar populations and should be evaluated in each setting so that this does not become a public health problem within the next few years.

    Full Text Available Abstract Goals The main purpose of this study is to broaden the clinicopathological spectrum and increase recognition of follicular dendritic cell sarcoma (FDCS through analysis of the clinical and pathological features of 50 cases. Methods The clinicopathological features of total 50 cases of FDCS were analyzed including a review of 44 cases reported in Chinese literature before October 2009 and six original cases from the pathology files conducted by the authors. Results The youngest patient came under observation in this study is only seven years old. Including the cases contributed by the authors, our literary review indicated that male dominated the tumor cases (M: F = 3: 2. 28 cases (56% present with this disease in extranodal sites. Tumor cells demonstrated positive staining for the follicular dendritic cell markers CD21 (47/49, CD35 (43/45, CD23 (20/23 and CD68 (23/25. In situ hybridization for Epstein-Barr virus-encoded RNA was performed in 10 cases. Nevertheless, EBV expression was absent in all these cases. The follow-up analysis of all cases shows that 26 (81.2% patients were alive and disease free; 6 (18.8% patients were alive with recurrent disease or metastasis; and nobody had died of this disease at the time of last follow-up. Conclusions The diagnosis of the FDCS is based on the findings of morphology and immunohistochemistry. The FDCS occurred in China should be viewed and treated as a low-grade sarcoma, and the role of the EBV in the pathogenesis of this tumor is still uncertain. There is a possibility that the tumor might be racial or geographic correlated, because most cases were reported from Eastern Asia area; it's particular the case of the liver or spleen tumor.

    Objective To review the development of T follicular helper (TFH) cells and their role in systemic lupus erythematosus (SLE) pathogenesis,the effect of dendritic cells (DCs) on TFH cells in SLE,as well as the potential use of TFH cells as a new therapeutic target in clinical practice.Data sources The data used in this review were retrieved mainly from the PubMed database (1989-2013).The terms used in the literature search were "T follicular helper cells," "systemic lupus erythematosus," and "dendritic cells." Study selection Relevant publications about the TFH cells development,the interaction between the TFH cells and the DCs,and the clinical applications of TFH cells were identified,retrieved,and reviewed.Results TFH cells,a novel distinct CD4+ T cell subset,are specialized in providing help to B cells in the formation of germinal centers (GCs) and long-term protective humoral immune responses.The development of TFH cells from na(i)ve CD4+ T cell is a multistep process.As the pivot of immunoregulation,DCs are indispensable for TFH cells generation.In addition to receptor-ligand interactions between TFH cells and DCs,the cytokines secreted by DCs are also necessary for TFH cell generation.TFH cell dysregulation has been implicated in the development of SLE.More evidence from animal models of SLE and SLE patients suggests that TFH cells are necessary for pathogenic autoantibody production.Therefore,therapeutically targeting TFH cells can be a promising approach to treat antibody-mediated autoimmune diseases including SLE.Conclusion TFH cells play a critical role in the pathogenesis of SLE,making them attractive therapeutic targets in clinical practice.

There is therefore a necessity for an adjuvant that maintains the quality of life (QOL and immune function of cancer patients receiving anthracycline-based chemotherapies.Patients and methods: The present study investigated the effectiveness of the concomitant use of Lentinula edodes mycelia extract (LEM, an oral immunomodulator, with FEC75 (5-fluorouracil + epirubicin + cyclophosphamide therapy on host QOL and immune function in breast cancer patients with nodal metastases. Ten breast cancer patients with nodal metastases receiving surgery were enrolled in this study. Treatment with 5-fluorouracil (500 mg/m2, epirubicin (75 mg/m2, and cyclophosphamide (500 mg/m2 was performed every 21 days for two courses, and LEM (1800 mg/day by mouth was administered during the second course.Results: In the first course, hematological toxicity was observed and host QOL and immune function were exacerbated. In the second course, however, the number of white blood cells and lymphocytes did not decrease and host QOL was maintained. Furthermore, the cytotoxic activities of natural killer (NK and lymphokine-activated killer cells and the proportion of activated NK and NK T-cells in lymphocytes were maintained in the second course.Conclusion: It has been suggested that the concomitant use of LEM with FEC75 therapy can maintain host QOL and immune function, and offer important implications for an application of LEM as a useful oral adjuvant to anthracycline-based chemotherapies

    Cisplatin (CP), an antitumor agent, has been shown to cause ovarian injury and dysfunction in both animal and human studies. The present study was conducted to investigate the protective effect of oxytocin (OT) on CP-induced ovarian toxicity in rats. Twenty-one adult female rats were included in the study. Fourteen rats were administered intraperitoneally CP (2 mg/kg/day) twice a week for 5 weeks. Control group (n = 7) did not receive any treatment. Following treatment, CP-received rats were randomly divided into two groups and treated with either saline (1 mL/kg/day, n = 7) or OT (160 μg/kg/day, n = 7) for 5 weeks. Then, ovarian toxicity and effects of OT were evaluated by histomorphological and biochemical analysis. Our findings revealed a significant reduction in the number of follicles at each grade in saline-treated group. AMH level was significantly lower in saline group compared to control (P CP toxicity in ovaries and increased AMH levels compared to saline group (P CP-treated rats (P CP-induced ovarian damage and improve follicular reserve by preventing oxidative damage.

    Full Text Available Abstract Follicular thyroid carcinoma (FTC tends to metastasize to remote organs rather than local lymph nodes. Separation of FTC from follicular thyroid adenoma (FTA relies on detection of vascular and/or capsular invasion. We investigated which vascular markers, CD31, CD34 and D2-40 (lymphatic vessel marker, can best evaluate vascular invasion and why FTC tends to metastasize via blood stream to remote organs. Thirty two FTCs and 34 FTAs were retrieved for evaluation. The average age of patients with FTA was 8 years younger than FTC (p = 0.02. The female to male ratio for follicular neoplasm was 25:8. The average size of FTC was larger than FTA (p = 0.003. Fourteen of 32 (44% FTCs showed venous invasion and none showed lymphatic invasion, with positive CD31 and CD34 staining and negative D2-40 staining of the involved vessels. The average number of involved vessels was 0.88 ± 1.29 with a range from 0 to 5, and the average diameter of involved vessels was 0.068 ± 0.027 mm. None of the 34 FTAs showed vascular invasion. CD31 staining demonstrated more specific staining of vascular endothelial cells than CD34, with less background staining. We recommended using CD31 rather than CD34 and/or D2-40 in confirming/excluding vascular invasion in difficult cases. All identified FTCs with vascular invasions showed involvement of venous channels, rather than lymphatic spaces, suggesting that FTCs prefer to metastasize via veins to distant organs, instead of lymphatic vessels to local lymph nodes, which correlates with previous clinical observations.

  14. Do alterations in follicular fluid proteases contribute to human infertility?

    Science.gov (United States)

    Cookingham, Lisa Marii; Van Voorhis, Bradley J; Ascoli, Mario

    2015-05-01

    Cathepsin L and ADAMTS-1 are known to play critical roles in follicular rupture, ovulation, and fertility in mice. Similar studies in humans are limited; however, both are known to increase during the periovulatory period. No studies have examined either protease in the follicular fluid of women with unexplained infertility or infertility related to advanced maternal age (AMA). We sought to determine if alterations in cathepsin L and/or ADAMTS-1 existed in these infertile populations. Patients undergoing in vitro fertilization (IVF) for unexplained infertility or AMA-related infertility were prospectively recruited for the study; patients with tubal or male factor infertility were recruited as controls. Follicular fluid was collected to determine gene expression (via quantitative polymerase chain reaction), enzyme concentrations (via enzyme-linked immunosorbent assays), and enzymatic activities (via fluorogenic enzyme cleavage assay or Western blot analysis) of cathepsin L and ADAMTS-1. The analysis included a total of 42 patients (14 per group). We found no statistically significant difference in gene expression, enzyme concentration, or enzymatic activity of cathepsin L or ADAMTS-1 in unexplained infertility or AMA-related infertility as compared to controls. We also found no statistically significant difference in expression or concentration with advancing age. Cathepsin L and ADAMTS-1 are not altered in women with unexplained infertility or AMA-related infertility undergoing IVF, and they do not decline with advancing age. It is possible that differences exist in natural cycles, contributing to infertility; however, our findings do not support a role for protease alterations as a common cause of infertility.

    The lines of Blaschko are a cutaneous pattern of mosaicism present in a variety of skin disorders. Developmental abnormalities affecting other tissues derived from the embryonic ectoderm and mesoderm are sometimes associated. Here, we describe a 5-year-old boy with basaloid follicular hamartoma affecting the left side of the body in linear multiple bands, following Blaschko lines. Lesions were predominantly hypopigmented macules and streaks, but among these, we could observe brownish atrophic patches and brown papules. Furthermore, ipsilateral hemimegaloencephaly and microphthalmia were present. These findings suggest a neurocutaneous condition recently described by Happle and Tinschert. Its nosologic classification will be discussed. © 2010 Wiley Periodicals, Inc.

    Full Text Available Case summary A 9-year-old spayed female domestic shorthair cat was examined for swelling of the right upper lip. The cat had been receiving oral ciclosporin A for eosinophilic plaques. The swelling appeared clinically and cytologically consistent with an abscess; exudate was cultured and treatment consisted of antibiotic therapy and surgical curettage. Five months of antibiotic therapy with three separate surgical treatments resulted in minimal improvement; three separate biopsy samples demonstrated epithelial cysts with severe dermal inflammation. Swelling and drainage of purulent material from the affected lip persisted and progressed to involve the left upper lip. Euthanasia was elected 13 months after initial examination due to disease progression. On necropsy, histopathology demonstrated multiple isthmus cysts intermixed with squamous cell carcinoma (SCC. Relevance and novel information The clinical and histopathologic features were unusual for feline cutaneous SCC. The cystic nature and lack of epidermal involvement suggest the tumor arose from non-epidermal squamous cells such as follicular isthmus or ductal epithelium. There is a pattern of SCC recognized in human renal transplant patients with features of epidermal inclusion cysts. These features have not been previously reported in SCC from a cat.

  19. A case of transient zinc deficiency in a breast-fed preterm infant successfully treated with oral zinc supplementation: review of zinc metabolism and related diseases.

    2009-12-01

    A 15-week-old baby girl, born at the 29 week of gestation, presented with a four-week history of demarcated, erythematous, erosive and exudative patches on the perianal, perioral and acral areas. A clinical diagnosis of zinc deficiency was considered. Serum zinc level was decreased (0.5 mg/L; normal 0.70-1.50 mg/L), the mother's serum and milk had normal zinc values. The baby was started an empiric trial of oral zinc supplementation (3 mg zinc gluconate/kg body weight/ day) with complete healing of lesions after two weeks. Treatment was gradually withdrawn at six months of age with no relapse. Transient zinc deficiency due to increased zinc requirements in breast-fed mainly preterm infants is a condition similar to acrodermatitis enteropathica, an autosomal recessive disorder of enteric zinc absorption affecting almost exclusively not breast-fed infants. Early recognition of the disorder and introduction of zinc supplementation rapidly reverses transient zinc deficiency, that probably will become more and more frequent, because of the rising rate of premature infants with breast-feeding only.

    Various components of follicular fluid are suggested as biochemical predictors of oocyte quality. Previous studies of follicular steroid hormone levels have shown disparate results when related with fertilization outcomes. The objective of the study was to relate the levels of steroid hormones of each individual follicle with oocyte maturation, fertilization results, embryo quality, and pregnancy rates. Prospective cohort study in a university hospital. In 31 patients, who underwent intracytoplasmic sperm injection, it was performed an ultrasound guided aspiration of follicular fluid of the first two mature follicles from each ovary. Follicular levels of estradiol, progesterone, testosterone, and dehydroepiandrosterone sulfate were measured by chemiluminescent immunoassay. Generalized estimating equation model. In follicular fluids with mature oocyte presence, in normal as well as in failed fertilization, there was a positive correlation between follicular testosterone and progesterone (r = 0.794, P = 0.0001 and r = 0.829, P = 0.0001). Progesterone levels were higher in cases of normal fertilization compared to failed fertilization (P = 0.003). B quality embryos came from oocytes immersed in follicular fluids with higher estradiol values and higher estradiol/progesterone and estradiol/testosterone ratios than those of C quality (P = 0.01; P = 0.0009; P = 0.001). Estradiol levels were higher in patients who achieved pregnancy (P = 0.02). The analysis of follicular hormone composition could be considered as an additional tool in oocyte selection.

    Full Text Available Aim: To evaluate the follicular dynamics, superovulatory response, and embryo recovery following superstimulatory treatment initiated at estradiol-17β induced follicular wave emergence and its comparison with conventional superstimulatory protocol in buffaloes. Materials and Methods: Six normal cycling pluriparous buffaloes, lactating, 90-180 days post-partum, and weighing between 500 and 660 kg were superstimulated twice with a withdrawal period of 35 days in between two treatments. In superstimulation protocol-1 (estradiol group buffaloes were administered estradiol-17β (2 mg, i.m. and eazibreed controlled internal drug release (CIDR was inserted intravaginally (day=0 at the random stage of the estrous cycle. On the day 4, buffaloes were superstimulated using follicle stimulating hormone (FSH 400 mg, divided into 10 tapering doses given at 12 hourly intervals. Prostaglandin F2α analogs (PGF2α was administered at day 7.5 and day 8, and CIDR was removed with the second PGF2α injection. In superstimulation protocol - 2 (conventional group buffaloes were superstimulated on the 10th day of the estrous cycle with same FSH dose regimen and similar timings for PGF2α injections. In both groups, half of the buffaloes were treated with luteinizing hormone (LH 25 mg and other half with 100 ug buserelin; gonadotrophin releasing hormone (GnRH analog at 12 h after the end of FSH treatment. All buffaloes in both protocols were inseminated twice at 12 and 24 h of LH/GnRH treatment. Daily ultrasonography was performed to record the size and number of follicles and superovulatory response. Results: Significantly higher number of small follicles (8 mm, corpora lutea, and transferable embryos was higher in buffaloes superstimulated at estradiol-induced follicular wave compared to the conventional protocol: Further the percentage of transferable embryos was significantly higher in buffaloes administered with LH compared to GnRH.

    Full Text Available Cytokines are key modulators of the immune system and also contribute to regulation of the ovarian cycle. In this study, Bender MedSystems FlowCytomix technology was used to analyze follicular cytokines (proinflammatory: IL-1β, IL-6, IL-18, IFN-γ, IFN-α, TNF-α, IL-12, and IL-23;, and anti-inflammatory: G-CSF, chemokines (MIP-1α, MIP-1β, MCP-1, RANTES, and IL-8, and other biomarkers (sAPO-1/Fas, CD44(v6 in 153 women undergoing in vitro fertilization (IVF. Cytokine origin was studied by mRNA analysis of granulosa cells. Higher follicular MIP-1α and CD44(v6 were found to correlate with polycystic ovary syndrome, IL-23, INF-γ, and TNF-α with endometriosis, higher CD44(v6 but lower IL-β and INF-α correlated with tubal factor infertility, and lower levels of IL-18 and CD44(v6 characterized unexplained infertility. IL-12 positively correlated with oocyte fertilization and embryo development, while increased IL-18, IL-8, and MIP-1β were associated with successful IVF-induced pregnancy.

  5. Embolization for vertebral metastases of follicular thyroid carcinoma.

    2000-03-01

    The technique of selective embolization has been applied for years in the treatment of vascular anomalies, severe hemorrhage and benign or malignant tumors, notably vertebral metastases of renal cell carcinoma. Because this technique is relatively easy to perform and offers immediate relief of symptoms, it is an attractive option for patients with vertebral metastases of thyroid carcinoma with signs of spinal cord compression. In these patients, other treatment modalities like radioactive iodine, external irradiation, or surgery are more cumbersome or less effective in the short term. We describe four patients with metastasized follicular thyroid carcinoma, presenting with neurological symptoms due to vertebral metastases. All patients had undergone total thyroidectomy, ranging from 1 month to 4 yr before embolization. Embolization was combined with iodine-131 therapy when appropriate. Selective catheterization of the arteries feeding the metastases was performed, followed by infusion of polyvinyl alcohol particles (Ivalon). The procedure was technically successful in all patients without adverse effects. In the patients described, embolization resulted in rapid resolution of neurological symptoms, sometimes within hours. The therapeutic effect lasted from months to years. We conclude that embolization of vertebral metastases of follicular thyroid carcinoma is an attractive palliative therapeutic option that may offer rapid relief of symptoms.

    A 61-yr-old woman presented with complaints of weakness and pain in her legs. A magnetic resonance imaging showed a 3 x 5.6 x 7.8 cm mass lesion destructing the T1 and T2 vertebral bodies and compressing the spinal cord. The mass was excised surgically. It was follicular carcinoma metastasis of the cervicodorsal region. Then, she underwent a total thyroidectomy. Pathological examination showed two different types of carcinomas in two different focuses; follicular carcinoma in the left lobe and follicular variant papillary carcinoma in the isthmic lobe. After the operation she was given 100 mCi 131I. This is the first report of a patient who had both metastatic follicular carcinoma and follicular variant papillary carcinoma together.

    2009-01-01

    Since the introduction of fine needle aspiration biopsy (FNAB) in the 1970's, a preoperative diagnostic technique for thyroid follicular carcinoma has long been awaited. Many markers that distinguish follicular carcinomas from adenomas have been reported; however, most of them have not been confirmed to be beneficial for clinical use. Trefoil factor 3 (TFF3) is a relatively new family of peptides that bears the three-loop trefoil domain. Several groups have reported that the suppression of TFF3 mRNA expression is related to malignant characteristics of thyroid follicular cell-derived tumors and the expression level of TFF3 mRNA is the most promising indicator for diagnosing follicular carcinoma. Development of TFF3-based diagnostic methods is now ongoing and it may not be long before thyroid follicular carcinoma can be diagnosed preoperatively using an aspirated sample from the tumor.

    Objective This study aimed to determine the threshold of anti-Müllerian hormone (AMH) as predictor of follicular growth failure in polycystic ovary syndrome (PCOS) patients treated with clomiphene citrate (CC). Methods Fifty female subjects with PCOS were recruited and divided into two groups based on successful and unsuccessful follicular growth. Related variables such as age, infertility duration, cigarette smoking, use of Moslem hijab, sunlight exposure, fiber intake, body mass index, waist circumference, AMH level, 25-hydroxy vitamin D level, and growth of dominant follicles were obtained, assessed, and statistically analyzed. Results The AMH levels of patients with successful follicular growth were significantly lower (p=0.001) than those with unsuccessful follicular growth (6.10±3.52 vs. 10.43±4.78 ng/mL). A higher volume of fiber intake was also observed in the successful follicular growth group compared to unsuccessful follicular growth group (p=0.001). Our study found the probability of successful follicle growth was a function of AMH level and the amount of fiber intake, expressed as Y=–2.35+(–0.312×AMH level)+(0.464×fiber intake) (area under the curve, 0.88; 95% confidence interval, 0.79–0.98; p<0.001). Conclusion The optimal threshold of AMH level in predicting the failure of follicle growth in patients with PCOS treated with CC was 8.58 ng/mL. PMID:28090459

    Background: Patients with atrial fibrillation who undergo intracoronary stenting traditionally are treated with a vitamin K antagonist (VKA) plus dual antiplatelet therapy (DAPT), yet this treatment leads to high risks of bleeding. We hypothesized that a regimen of rivaroxaban plus a P2Y12 inhibitor monotherapy or rivaroxaban plus DAPT could reduce bleeding and thereby have a favorable impact on all-cause mortality and the need for rehospitalization. Methods: Stented subjects with nonvalvular atrial fibrillation (n=2124) were randomized 1:1:1 to administration of reduced-dose rivaroxaban 15 mg daily plus a P2Y12 inhibitor for 12 months (group 1); rivaroxaban 2.5 mg twice daily with stratification to a prespecified duration of DAPT of 1, 6, or 12 months (group 2); or the reference arm of dose-adjusted VKA daily with a similar DAPT stratification (group 3). The present post hoc analysis assessed the end point of all-cause mortality or recurrent hospitalization for an adverse event, which was further classified as the result of bleeding, a cardiovascular cause, or another cause blinded to treatment assignment. Results: The risk of all-cause mortality or recurrent hospitalization was 34.9% in group 1 (hazard ratio=0.79; 95% confidence interval, 0.66–0.94; P=0.008 versus group 3; number needed to treat=15), 31.9% in group 2 (hazard ratio=0.75; 95% confidence interval, 0.62–0.90; P=0.002 versus group 3; number needed to treat=10), and 41.9% in group 3 (VKA+DAPT). Both all-cause death plus hospitalization potentially resulting from bleeding (group 1=8.6% [P=0.032 versus group 3], group 2=8.0% [P=0.012 versus group 3], and group 3=12.4%) and all-cause death plus rehospitalization potentially resulting from a cardiovascular cause (group 1=21.4% [P=0.001 versus group 3], group 2=21.7% [P=0.011 versus group 3], and group 3=29.3%) were reduced in the rivaroxaban arms compared with the VKA arm, but other forms of rehospitalization were not. Conclusions: Among patients with

    Trimethoprim is well known to cause rashes; however, what is not commonly known is that it causes sudden and profound hyperkalemia in 10 to 20% of treated patients. The uniqueness of burn patients begs the question whether changes known to occur in these patients might also increase this trimethoprim effect. After institutional review board approval, a retrospective study evaluated 224 patients with thermal injury who had been treated with trimethoprim sulfamethoxazole (TMP-SMX), 24 of whom had underlying renal impairment (creatinine clearances drug-induced hyperkalemia were used: 1) a ≥ 1 mEq/L rise, 2) a >0.8 mEq rise in potassium in hyperkalemia defined as serum potassium of ≥ 5.5 mEq/L within 48 hours. A potassium level before trimethoprim exposure (TxK) and after TxK were collected retrospectively. Demographic data were analyzed with Student's t-test and trimethoprim dose alone, demonstrating a significant difference. Analysis of 200 patients exposed to trimethoprim demonstrated an elevation of potassium (first definition) in 31 patients (15.5%), a rapid change in serum potassium in two patients (second definition), and marked hyperkalemia (>5.5 mEq/L) in 13 patients (6.5%). Hyperkalemia never occurred in 166 of 200 patients (82%; before TxK, 3.9 ± 0.4; after TxK, 4.3 ± 0.5 mEq/L). Change in serum potassium among patients with hyperkalemia was 4.0 ± 0.5 mEq/L before TxK and 5.3 ± 0.7 mEq/L after TxK. Twelve published hyperkalemia risk factors were reviewed in these 200 patients and only history of hypertension and need for intubation was more common in those with hyperkalemia. A nearly 20% incidence of hyperkalemia and 6% serious hyperkalemia in burn patients is consistent with reports in patients without burn injury. These data also suggest that the metabolic and hormonal changes associated with burn injury do not increase further the genetically predisposed hyperkalemia resulting from exposure to trimethoprim. These data suggest patients treated with

    Background Body hair shafts from the beard, trunk, and extremities can be used to treat baldness when patients have inadequate amounts of scalp donor hair, but reports in the literature concerning use of body hair to treat baldness are confined to case reports. Objectives This study aimed to assess the outcome of body hair transplanted to bald areas of the scalp in selected patients. Methods From 2005 through 2011, 122 patients preselected for adequate body hair had donor hair transplanted from the beard, trunk, and the extremities to the scalp by follicular unit extraction (FUE) by the author at a single center. All patients were emailed surveys to assess surgical outcomes and overall satisfaction. Results Seventy-nine patients (64.8%) responded with a mean time of 2.9 years between date of last surgery and time of survey. Patients were generally very satisfied with results of their procedure, giving mean scores of at least a 7.8 on a Likert-like scale of 0 to 10 for their healing status, hair growth in recipient areas, and overall satisfaction with their surgeries. These scores were comparable to mean scores provided by patients whose transplants included scalp donor sources. Conclusions FUE using body hair can be an effective hair transplantation method for a select patient population of hirsute individuals who suffer from severe baldness or have inadequate scalp donor reserve.

    AIM To retrospectively evaluate the efficacy and safety of risperidone oral solution and risperidone tablets in treating schizophrenia. METHODS A total of 204 patients, who met diagnostic criteria of CCMD-3 for schizophrenia and were hospitalized in our department of psychiatry from May 2007 to May 2011, included 85 patients in risperidone oral solution group and 119 patients in risperidone tablets group. Before the treatment and at the end of the 4 th week of the treatment, all patients were assessed by Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Negative Symptoms (SANS), Scale for the Assessment of Positive Symptoms (SAPS), Treatment Emergent Symptom Scale (TESS) and laboratory tests. RESULTS There were significant differences in total scales of TESS and the rates of ECG abnormalities and extrapyramidal side effects between the risperidone oral solution group and risperidone tablets group (6.62 ± 3.65 vs. 7.97 ± 4.93, 16.5%vs. 28.6%, 23.5% vs. 40.3%, P0.05) in the total scales of BPRS, SANS, SAPS and other index of safety. CONCLUSION The efficacy of risperidone oral solution and risperidone tablets in treating schizophrenia was equal, but risperidone oral solution is superior to risperidone tablets on the safety.%目的 比较利培酮口服液与利培酮片剂治疗精神分裂症的疗效与安全性.方法 回顾性分析2007年5月至201 1年5月在本科室住院4 wk以上,符合CCMD-3精神分裂症诊断标准的患者共204例,其中利培酮口服液组85例,利培酮片剂组119例.比较2组患者治疗前与治疗4 wk末简明精神病评定量表、阳性症状量表、阴性症状量表、副反应量表总分以及实验室检查的差异.结果 2组治疗4 wk末简明精神病评定量表、阳性症状量表、阴性症状量表分值无显著差异(P>0.05).利培酮口服液组副反应量表总分、心电图异常发生率以及锥体外系反应发生率明显低于利培酮片剂组(6.62±3.65 vs.7.97±4.93,16.5

    To evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of odanacatib (ODN), a cathepsin K inhibitor, in humans. Two double-blind, randomized, placebo-controlled, single oral dose studies were performed with ODN (2-600 mg) in 44 healthy volunteers (36 men and eight postmenopausal women). Adverse experiences (AEs) with single doses of ODN were transient and mild to moderate, with the exception of one severe AE of gastroenteritis. Headache was the most frequent AE. After absorption of ODN (initial peak concentrations 4-6 h postdose), plasma concentrations exhibited a monophasic decline, with an apparent terminal half-life of ∼40-80 h. The area under the curve0-24 hours (AUC(0-24 h)), concentration at 24 hours (C(24 h)) and maximum concentration (C(max,overal)) increased in a less than dose-proportional manner from 2 to 600 mg. Administration of ODN with a high-fat meal led to ∼100% increases in AUC(0-24 h), C(max,day1), C(max,overall) and C(24 h) relative to the fasted state, while administration with a low-fat meal led to a ∼30% increase in those parameters. Reduction of biomarkers of bone resorption, the C- and N-telopeptides of cross-links of type I collagen, (CTx and NTx, respectively), was noted at 24 h for doses ≥5 mg and at 168 h postdose for ≥10 mg. In postmenopausal women administered 50 mg ODN, reductions in serum CTx of -66% and urine NTx/creatinine (uNTx/Cr) of -51% relative to placebo were observed at 24 h. At 168 h, reductions in serum CTx (-70%) and uNTx/Cr (-78%) were observed relative to baseline. Pharmacokinetic/pharmacodynamic modeling characterized the ODN concentration/uNTx/Cr relation, with a modeled EC50 value of 43.8 nM and ∼80% maximal reduction. Odanacatib was well tolerated and has a pharmacokinetic and pharmacodynamic profile suitable for once weekly dosing. © 2012 Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Whitehouse Station, NJ, USA.

    Could cell-free DNA (cfDNA) quantification in individual human follicular fluid (FF) samples become a new non-invasive predictive biomarker for in vitro fertilization (IVF) outcomes? CfDNA level in human follicular fluid samples was significantly correlated with embryo quality and could be used as an innovative non-invasive biomarker to improve IVF outcomes. CfDNA fragments, resulting from apoptotic or necrotic events, are present in the bloodstream and their quantification is already used as a biomarker for gynaecological and pregnancy disorders. Follicular fluid is important for oocyte development and contains plasma components and factors secreted by granulosa cells during folliculogenesis. CfDNA presence in follicular fluid and its potential use as an IVF outcome biomarker have never been investigated. One hundred individual follicular fluid samples were collected from 43 female patients undergoing conventional IVF (n = 26) or ICSI (n = 17). CfDNA level was quantified in each individual follicular fluid sample. At oocyte collection day, follicles were aspirated individually. Only blood-free follicular fluid samples were included in the study. Follicle size was calculated based on the follicular fluid volume. Each corresponding cumulus-oocyte complex was isolated for IVF or ICSI procedures. Follicular fluid cfDNA was measured by quantitative PCR with ALU-specific primers. Human follicular fluid samples from individual follicles contain measurable amounts of cfDNA (mean ± SD, 1.62 ± 2.08 ng/µl). CfDNA level was significantly higher in small follicles (8-12 mm in diameter) than in large ones (>18 mm) (mean ± SD, 2.54 ± 0.78 ng/µl versus 0.71 ± 0.44 ng/µl, respectively, P = 0.007). Moreover, cfDNA concentration was significantly and negatively correlated with follicle size (r = -0.34; P = 0.003). A weak significant negative correlation between DNA integrity and 17β-estradiol level in follicular fluid samples at oocyte collection day was observed (r = -0

    Full Text Available Abstract Background The optimum oral pharmacological treatment of diabetes mellitus to reduce cardiovascular disease and mortality following myocardial infarction has not been established. We therefore set out to investigate the association between individual oral glucose-lowering drugs and cardiovascular outcomes following myocardial infarction in patients with diabetes mellitus not treated with emergent percutaneous coronary intervention. Materials and methods All patients aged 30 years or older receiving glucose-lowering drugs (GLDs and admitted with myocardial infarction (MI not treated with emergent percutaneous coronary intervention in Denmark during 1997-2006 were identified by individual-level linkage of nationwide registries of hospitalizations and drug dispensing from pharmacies. Multivariable Cox regression models adjusted for age, sex, calendar year, comorbidity, and concomitant pharmacotherapy were used to assess differences in the composite endpoint of non-fatal MI and cardiovascular mortality between individual GLDs, using metformin monotherapy as reference. Results The study comprised 9876 users of GLDs admitted with MI. The mean age was 72.3 years and 56.5% of patients were men. A total of 3649 received sulfonylureas and 711 received metformin at admission. The average length of follow-up was 2.2 (SD 2.6 years. A total of 6,171 patients experienced the composite study endpoint. The sulfonylureas glibenclamide, glimepiride, glipizide, and tolbutamide were associated with increased risk of cardiovascular mortality and/or nonfatal MI with hazard ratios [HRs] of 1.31 (95% confidence interval [CI] 1.17-1.46, 1.19 (1.06-1.32, 1.25 (1.11-1.42, and 1.18 (1.03-1.34, respectively, compared with metformin. Gliclazide was the only sulfonylurea not associated with increased risk compared with metformin (HR 1.03 [0.88-1.22]. Conclusions In patients with diabetes mellitus admitted with MI not treated with emergent percutaneous coronary

    Follicular wave emergence was synchronized by treating camels with GnRH when a dominant follicle (DF) was present in the ovaries. Animals were scanned twice a day from day 0 (day of GnRH treatment) to day 10, to characterize emergence and deviation of follicles during the development of the follicular wave. Follicle deviation in individual animals was determined by graphical method. Single DFs were found in 16, double DFs in 9 and triple DFs in two camels. The incidence of codominant (double and triple DFs) follicles was 41%. The interval from GnRH treatment to wave emergence, wave emergence to deviation, diameter and growth rate of F1 follicle before or after deviation did not differ between the animals with single and double DFs. The size difference between future DF(s) and the largest subordinate follicle (SF) was apparent from the day of wave emergence in single and double DFs. Overall, interval from GnRH treatment to wave emergence and wave emergence to the beginning of follicle deviation was 70.6 ± 1.4 and 58.6 ± 2.7 h, respectively. Mean size of the DF and largest SF at the beginning of deviation was 7.4 ± 0.2 and 6.3 ± 0.1 mm, respectively. In conclusion, the characteristics of follicle deviation are similar between the animals that developed single or double DFs.

    The mammalian oocyte nucleus or germinal vesicle (GV) exhibits characteristic chromatin configurations, which are subject to dynamic modifications through oogenesis. Aim of this review is to highlight how changes in chromatin configurations are related to both functional and structural modifications occurring in the oocyte nuclear and cytoplasmic compartments. During the long phase of meiotic arrest at the diplotene stage, the chromatin enclosed within the GV is subjected to several levels of regulation. Morphologically, the chromosomes lose their individuality and form a loose chromatin mass. The decondensed configuration of chromatin then undergoes profound rearrangements during the final stages of oocyte growth that are tightly associated with the acquisition of meiotic and developmental competence. Functionally, the discrete stages of chromatin condensation are characterized by different level of transcriptional activity, DNA methylation and covalent histone modifications. Interestingly, the program of chromatin rearrangement is not completely intrinsic to the oocyte, but follicular cells exert their regulatory actions through gap junction mediated communications and intracellular messenger dependent mechanism(s). With this in mind and since oocyte growth mostly relies on the bidirectional interaction with the follicular cells, a connection between cumulus cells gene expression profile and oocyte developmental competence, according to chromatin configuration is proposed. This analysis can help in identifying candidate genes involved in the process of oocyte developmental competence acquisition and in providing non-invasive biomarkers of oocyte health status that can have important implications in treating human infertility as well as managing breeding schemes in domestic mammals.

    Ovarian follicular kinetics and gravimetric changes in the ovary and oviducts were studied in the skipper frog, Rana cyanophlyctis, following exposure to continuous light and melatonin treatment during the breeding season. Daily late-afternoon injections of melatonin (15 micrograms subcutaneous) for 30 days decreased the gonadosomatic index (GSI), whereas continuously available melatonin from subcutaneous implants did not influence the GSI compared to those of controls. Exposure to continuous light for 30 days stimulated the GSI, and melatonin given as daily injections prevented the continuous-light induced increase in GSI. Oviductal weights decreased only in the melatonin-injected groups. Data on follicular kinetics revealed a decrease in first-growth-phase (FGP) oocytes and an increase in medium-sized second-growth-phase (MSGP) and large-sized second-growth-phase (LSGP) oocytes following continuous-light exposure. Melatonin administered to continuous-light-exposed frogs did not change the FGP oocyte number; however, it reduced both the MSGP and LSGP oocytes. Melatonin administration to frogs held in a light and dark cycle increased FGP oocytes and decreased MSGP and LSGP oocytes. Atretic follicles increased in all melatonin-treated groups. The results suggest that continuous light stimulates and melatonin inhibits reproductive function in this species.

    Full Text Available Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

    RAC1b is a hyperactive variant of the small GTPase RAC1 known to be a relevant molecular player in different cancers. Previous studies from our group lead to the evidence that its overexpression in papillary thyroid carcinoma (PTC) is associated with an unfavorable prognosis. In the present study, we intended to extend the analysis of RAC1b expression to thyroid follicular neoplasms and to seek for clinical correlations. RAC1b expression levels were determined by RT-qPCR in thyroid follicular tumor samples comprising 23 follicular thyroid carcinomas (FTCs) and 33 follicular thyroid adenomas (FTAs). RAC1b was found to be overexpressed in 33% of carcinomas while no RAC1b overexpression was documented among follicular adenomas. Patients with a diagnosis of FTC were divided into two groups based on longitudinal evolution and final outcome. RAC1b overexpression was significantly associated with both the presence of distant metastases (P = 0.01) and poorer clinical outcome (P = 0.01) suggesting that, similarly to that previously found in PTCs, RAC1b overexpression in FTCs is also associated with worse outcomes. Furthermore, the absence of RAC1b overexpression in follicular adenomas hints its potential as a molecular marker likely to contribute, in conjunction with other putative markers, to the preoperative differential diagnosis of thyroid follicular lesions.

    Full Text Available The aim of this study was to identify differentially expressed proteins in the follicular fluid of Tianzhu white yak during diestrus. Follicles obtained from female yak were divided into four groups according to their diameter: 0–2, 2–4, 4–6 mm, and greater than 6 mm. The follicular fluid was directly aspirated from the follicles and mixed according to follicular size, and two-dimensional gel electrophoresis was carried out on the crude follicular fluid samples. Thirty-four differentially expressed spots were generated from these four sizes of follicles. Fourteen of these spots were analyzed by MALDI-TOF/TOF-MS and identified as: AS3MT, VDP, ANKRD6, C10orf107 protein, MRP4, MAPKAP1, AGO3, profilin-β-actin, SPT2 homolog, AGP, AR, RNF20, obscurin-like-1, and one unnamed protein. These proteins were first reported in follicular fluid, in addition to VDP and AGP. Based on existing knowledge of their function and patterns of expression, we hypothesize that most of these differentially expressed proteins play a role in ovarian follicular growth and development, dominant follicle selection, or follicular atresia and development of oocytes; however, the function of the other differentially expressed proteins in reproduction remains ambiguous.

    Alopecia areata is an autoimmune disease targeted at hair follicles with infiltrated T lymphocytes probably playing an important role in the pathogenesis. It was reported in 1985 that mechlorethamine was effective on alopecia areata patients. This has never been confirmed since. The aims of the study were to investigate the effects of mechlorethamine on balding C3H/HeJ mice affected with an alopecia-areata-like disease and to study the underlying mechanisms. Mice were treated on half of the dorsal skin with mechlorethamine and the contralateral side was treated with the vehicle ointment. After 10 wk of mechlorethamine therapy, a full pelage of hair covered the treated side in all the mice and was maintained during the study, whereas the vehicle-treated sides showed either no change or continued hair loss. Immunohistochemistry revealed that infiltrated CD4+ and CD8+ lymphocytes were eliminated from the treated side. In vitro cell viability assay showed that lymphocytes were much more sensitive to the cytotoxic effects of mechlorethamine than skin and hair follicular cells. RNase protection assay and real-time reverse transcription polymerase chain reaction showed that tumor necrosis factor alpha/beta, interleukin-12, and interferon-gamma were inhibited by mechlorethamine upon successful treatment. Our findings support that mechlorethamine restores follicular activity by selectively targeting infiltrated lymphocytes in vivo in alopecia-areata-affected mice.

    Full Text Available Despite the success of antiretroviral therapy (ART, it does not cure Human Immunodeficiency Virus (HIV and discontinuation results in viral rebound. Follicular dendritic cells (FDC are in direct contact with CD4+ T cells and they retain intact antigen for prolonged periods. We found that human FDC isolated from patients on ART retain infectious HIV within a non-degradative cycling compartment and transmit infectious virus to uninfected CD4 T cells in vitro. Importantly, treatment of the HIV+ FDC with a soluble complement receptor 2 purges the FDC of HIV virions and prevents viral transmission in vitro. Our results provide an explanation for how FDC can retain infectious HIV for extended periods and suggest a therapeutic strategy to achieve cure in HIV-infected humans.

    Hair follicles represent interesting target sites for topically applied substances such as topical vaccinations or agents used in the field of regenerative medicine. In recent years, it could be shown that particles penetrate very effectively into the hair follicles. In the present study, the influence of particle size on the follicular penetration depths was examined. The penetration depths of two different types of particles sized 122 to 1000 nm were determined in vitro on porcine skin. The results revealed that the particles of medium size (643 and 646 nm, respectively) penetrated deeper into the porcine hair follicles than smaller or larger particles. It was concluded that by varying the particle size, different sites within the porcine hair follicle can be targeted selectively. For the human terminal hair follicle, the situation can be expected to be similar due to a similar size ratio of the hair follicles.

    Full Text Available Abstract The last two decades have witnessed striking advances in our understanding of the biological factors underlying the development of Follicular lymphoma (FL. Development of newer treatment approaches have improved the outlook for many individuals with these disorders; however, with these advances come new questions. Given the long-term survival of patients with FL, drugs with favourable side-effect profile and minimal long-term risks are desired. FL is incurable with current treatment modalities. It often runs an indolent course with multiple relapses and progressively shorter intervals of remission. The identification of new targets and development of novel targeted therapies is imperative to exploit the biology of FL while inherently preventing relapse and prolonging survival. This review summarizes the growing body of knowledge regarding novel therapeutic targets, enabling the concept of individualized targeted therapy for the treatment of FL.

    Full Text Available Summary: Fine hairs of the head and nape areas have been used as donor sources in eyelash transplantation but are straight, coarse, and grow rapidly, requiring frequent eyelash maintenance. This is the first reported case of eyelash transplantation by follicular unit extraction using leg hair as a donor source; findings were compared with that of another patient who underwent a similar procedure with donor hairs from the nape area. Although both patients reported marked improvement in fullness of eyelashes within 3 months postsurgery, the transplanted leg hair eyelashes required less frequent trimming (every 5–6 weeks compared with nape hair eyelashes (every 2–3 weeks. Additionally, in leg hair eyelashes, the need for perming to sustain a natural looking eyelash curl was eliminated. Eyelash transplantation using leg donor hair in hirsute women may result in good cosmetic outcomes and require less maintenance compared with nape donor hair.

    Granuiosa cells (GCs) are the most important cells in the ovary that undergo serious changes morphologically and physiologically during the processes of follicular proliferation, differentiation, ovulation, lutenization and atresia. Oocyte (OC) directs GC proliferation and differentiation, while GCs influence OC maturation. Many ovarian factors are involved in the regulation of these processes via different molecular mechanisms and signal pathways. P38MAPK can selectively regulate steroidogenesis in GCs controlled by FSH; Transcript factors LRH-1 and DAX-1 play an important role in this process; FSH induces GC prolfferation and differentiation by stimulating PCNA and StAR expression and steroidogenesis. Activated ERK1/2 signal pathway may be involved in the FSH-regulated GC proliferation and differentiation. Therefore, GC is an ideal model for studying cell proliferation, differentiation and interaction,as well as signal transduction. This review briefly summarizes the latest data in the literature, including the results achieved in our laboratory.

    The purpose of this study was to evaluate and compare the sonographic findings of a conventional papillary carcinoma, follicular carcinoma and a follicular variant of a papillary carcinoma. A total of 308 nodules from 231 patients that were diagnosed with a papillary carcinoma and a follicular carcinoma by surgery after sonography were analyzed. The nodules consisted of a conventional papillary carcinoma (255, 83%), a follicular variant of a papillary carcinoma (25, 8%), and a follicualar carcinoma (28, 9%). We compared and analyzed the sonographic findings of each nodule for content, margin, echotexture, shape, calcification and halo sign. A conventional papillary carcinoma showed significant different sonographic findings than a follicular carcinoma and a follicular variant of a papillary carcinoma for an ill-defined or well-defined spiculated margin (63.1%), marked hypoechogenicity (85.9%) and microcalcification (49%). A follicular carcinoma showed a significant difference than a conventional papillary carcinoma for a well-defined smooth margin (92.9%), iso, hypo- or hyperechogenicity (89.3%), wider than tall shape (100%) and halo sign (82.1%). The follicular variant of a papillary carcinoma showed similar findings to a follicular carcinoma except for marked hypoechogenicity (44%, p = 0.006) and taller than wide shape (16%, p = 0.027). The follicular carcinoma and follicular variant of a papillary carcinoma showed similar sonographic findings, but findings of a conventional papillary carcinoma were different

    Perfluoroalkyl acids (PFAAs) have been shown to induce negative effects in laboratory animals and in vitro experiments. Also, PFAAs have been detected in human tissues and body fluids. The ovarian follicle constitutes a fragile micro-environment where interactions between hormones, growth factors, the oocyte and surrounding somatic cells are essential to generate a fully competent oocyte. In vitro experiments suggest that PFAAs can influence this balance, but very scarce in vivo data are available to confirm this assumption. In fact, the potential PFAA-presence in the follicular micro-environment is currently unknown. Therefore, we investigated if PFAAs are present in human follicular fluid and if their presence could be a risk factor for in vivo exposed developing oocytes. Furthermore, we compared the PFAA-distribution within serum and follicular fluid. PFAAs were analyzed by LC/MS in follicular fluid (n=38) and serum (n=20) samples from women undergoing assisted reproductive technologies (ARTs). Statistical models were used to investigate PFAA-distribution in both body fluids, to compare this behavior with the distribution of lipophilic organic pollutants and to explore the relationship between patient characteristics, ART-results and follicular fluid contamination. Perfluorooctane sulfonate (PFOS) was the PFAA found in the highest concentration in follicular fluid [7.5 (0.1-30.4) ng/mL] and serum [7.6 (2.8-12.5) ng/mL]. A new variable, Principal Component 1, representing the overall PFAA-contamination of the follicular fluid samples, was associated with a higher fertilization rate (porganic pollutants as explanatory variables. To conclude, overall higher PFAA-contamination in the follicular micro-environment was associated with a higher chance of an oocyte to develop into a high quality embryo. Also, PFAAs have different distribution patterns between serum and follicular fluid compared to the lipophilic organic pollutants. Further research is of course crucial

    Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications.

    The study was undertaken to examine any differences existing in total cortisol concentrations in the follicular fluid (FF) of pre-ruptured follicles between 'low responder' patients (group 1, n = 20) and 'good responder' patients (group 2, n = 15). The groups were defined according to how many oocytes had been retrieved during the previous in-vitro fertilization procedure (group 1: three or fewer; group 2: more than three) and total oestradiol concentration at previous in-vitro fertilization (IVF) (group 1: 500 pg/ml). All patients were aged 36-43 years (group 1 mean +/- SD: 38.2 +/- 4.7; group 2: 32.1 +/- 3.8 years) and were diagnosed with tubal or unexplained infertility. The total FF cortisol concentrations obtained in conjunction with an IVF procedure were assayed and related to oocyte fertilization. Follicular fluid was analysed for total cortisol content. Only follicles between 19 and 20 mm diameter were analysed in both groups. After aspiration of blood-free FF, total cortisol concentrations were measured by radioimmunoassay, designed for the quantitative measurement of cortisol, and related to oocyte fertilization. Total cortisol concentration in FF from fertilized oocytes was 9.7 +/- 0.6 microg/ml (mean +/- SD) in group 1 compared to 9.2 +/- 4.4 microg/ml in group 2 (not statistically significant). Total cortisol concentrations were not associated with oocyte fertilization and no difference between the groups was found in total cortisol concentrations in the FF of unfertilized oocytes or empty follicles.

    A severe gonadotropin deficiency together with chronic estradiol deficiency leading to amenorrhea characterizes patients suffering from hypogonadotropic hypogonadism. Administration of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to these patients has been shown to be essential in achieving successful stimulation of follicular development, ovulation, and rescue of fertility. In recent years, the availability of both recombinant FSH (rFSH) and recombinant LH (rLH) has provided a new therapeutic option for the stimulation of follicular growth in hypopituitary-hypogonadotropic women (World Health Organization Group I). In this article, we review the data reported in the literature to highlight the role and the efficacy of using recombinant gonadotropins, rFSH and rLH, in the treatment of women with severe LH/FSH deficiency. Although the studies on this issue are limited and the experiences available in the literature are few due to the small number of such patients, it is clearly evident that the recombinant gonadotropins rFSH and rLH are efficient in treating patients affected by hypogonadotropic hypogonadism. The results observed in the studies reported in this review suggest that recombinant gonadotropins are able to induce proper follicular growth, oocyte maturation, and eventually pregnancy in this group of women. Moreover, the clinical use of recombinant gonadotropins in this type of patients has given more insight into some endocrinological aspects of ovarian function that have not yet been fully understood.

    Trefoil factor 3 (TFF3) is overexpressed in a variety of solid epithelial cancers, where it has been shown to promote migration, invasion, proliferation, survival and angiogenesis. On the contrary, in the majority of thyroid tumors, it is downregulated, yet its role in the development of thyroid cancer remains unknown. Here we show that TFF3 exhibits strong cytoplasmic staining of normal thyroid follicular cells and colloid and the staining is increased in hyperfunctioning thyroid nodules, while it is decreased in all thyroid cancers of follicular cell origin. By meta-analysis of gene expression datasets, we found that in the thyroid cancer, conversely to the breast cancer, the expression of TFF3 mRNA was downregulated by estrogen signaling and confirmed this by treating thyroid cancer cells with estradiol. Forced expression of TFF3 in anaplastic thyroid cancer cells resulted in decreased cell proliferation, clonal spheroid formation and entry into the S phase. Furthermore, it induced acquisition of epithelial-like cell morphology and expression of the differentiation markers of thyroid follicular cells and transcription factors implicated in the thyroid morphogenesis and function. Taken together, this study provides the first evidence that TFF3 may act as a tumor suppressor or an oncogene depending on the cellular context.

    Full Text Available Dowling Degos disease is a rare, reticulate pigmentary disorder with variable phenotypic expression that manifests as hyperpigmented macules and reticulate pigmentary anomaly of the flexures. Many variants of this condition and its overlap with other reticulate pigmentary disorders have been reported in the literature. We present here two cases of DDD with follicular localization, both clinically and histologically. It was associated with ichthyosis vulgaris in one case. Follicular DDD is an uncommon variant of this evolving dermatosis. Our report supports the possible role for disordered follicular keratinisation in its pathogenesis.

    2009-10-01

    Full Text Available Abstract Background Carcinoma of the thyroid gland is an uncommon cancer, but the most frequent malignancy of the endocrine system. Most thyroid cancers are derived from the follicular cell. Follicular carcinoma (FTC is considered more malignant than papillary thyroid carcinoma (PTC, and anaplastic thyroid cancer (ATC is one of the most lethal human cancers. Opioid Growth Factor (OGF; chemical term - [Met5]-enkephalin and its receptor, OGFr, form an inhibitory axis regulating cell proliferation. Both the peptide and receptor have been detected in a wide variety of cancers, and OGF is currently used clinically as a biotherapy for some non-thyroid neoplasias. This study addressed the question of whether the OGF-OGFr axis is present and functional in human thyroid follicular cell - derived cancer. Methods Utilizing human ATC (KAT-18, PTC (KTC-1, and FTC (WRO 82-1 cell lines, immunohistochemistry was employed to ascertain the presence and location of OGF and OGFr. The growth characteristics in the presence of OGF or the opioid antagonist naltrexone (NTX, and the specificity of opioid peptides for proliferation of ATC, were established in KAT-18 cells. Dependence on peptide and receptor were investigated using neutralization studies with antibodies and siRNA experiments, respectively. The mechanism of peptide action on DNA synthesis and cell survival was ascertained. The ubiquity of the OGF-OGFr axis in thyroid follicular cell-derived cancer was assessed in KTC-1 (PTC and WRO 82-1 (FTC tumor cells. Results OGF and OGFr were present in KAT-18 cells. Concentrations of 10-6 M OGF inhibited cell replication up to 30%, whereas NTX increased cell growth up to 35% relative to cultures treated with sterile water. OGF treatment reduced cell number by as much as 38% in KAT-18 ATC in a dose-dependent and receptor-mediated manner. OGF antibodies neutralized the inhibitory effects of OGF, and siRNA knockdown of OGFr negated growth inhibition by OGF. Cell survival

  16. A Honey Trap for the Treatment of Acne: Manipulating the Follicular Microenvironment to Control Propionibacterium acnes

    2013-01-01

    Full Text Available Today, as 40 years ago, we still rely on a limited number of antibiotics and benzoyl peroxide to treat inflammatory acne. An alternative way of suppressing the growth of Propionibacterium acnes is to target the environment in which it thrives. We conjecture that P. acnes colonises a relatively “extreme” habitat especially in relation to the availability of water and possibly related factors such as ionic strength and osmolarity. We hypothesise that the limiting “nutrient” within pilosebaceous follicles is water since native sebum as secreted by the sebaceous gland contains none. An aqueous component must be available within colonised follicles, and water may be a major factor determining which follicles can sustain microbial populations. One way of preventing microbial growth is to reduce the water activity ( of this component with a biocompatible solute of very high water solubility. For the method to work effectively, the solute must be small, easily diffusible, and minimally soluble in sebaceous lipids. Xylose and sucrose, which fulfil these criteria, are nonfermentable by P. acnes and have been used to reduce water activity and hence bacterial colonisation of wounds. A new follicularly targeted topical treatment for acne based on this approach should be well tolerated and highly effective.

    Full Text Available Chylothorax is caused by disruption or obstruction of the thoracic duct or its tributaries that results in the leakage of chyle into the pleural space. A number of interventions have been used to treat chylothorax including the treatment of the underlying disease. Lymphoma is found in 70% of cases with nontraumatic malignant aetiology. Although patients usually have advanced lymphoma, supradiaphragmatic disease is not always present. We discuss the case of a 63-year-old woman presenting with progressive respiratory symptoms due to chylothorax. She was diagnosed with a stage IIE retroperitoneal grade 1 follicular lymphoma extending from the coeliac trunk towards the pelvic inlet. Despite thoracocentesis and medium-chain triglycerides (MCT, diet chylothorax reoccurred. After low dose radiotherapy (2×2 Gy to the abdominal lymphoma there was a marked decrease in lymphadenopathy at the coeliac trunk and a complete regression of the pleural fluid. In this case, radiotherapy was shown to be an effective nontoxic treatment option for lymphoma-associated chylothorax with long-term remission of pleural effusion.

    There are three subtypes of follicular variant papillary thyroid carcinoma (fvPTC): completely encapsulated, well circumscribed, and infiltrative. While infiltrative tumors are more aggressive than completely encapsulated, controversy exists regarding management of fvPTC subtypes. We compared the clinicopathologic features of fvPTC subtypes to those of classic PTC (cPTC) to help guide fvPTC management, using cPTC as a reference. A retrospective review was performed on 316 patients with PTC treated at a single institution from 2004 to 2011. There were 197 cPTC and 119 fvPTC tumors, including completely encapsulated (n = 46), well circumscribed (n = 46), and infiltrative (n = 27). Clinicopathologic data were compared between groups. fvPTC patients had larger tumors than cPTC patients (1.6 cm vs. 1.2 cm, p = 0.001), but age, sex, and family history did not differ. Thirty-one percent of cPTC tumors had extrathyroidal extension compared to 0 % of completely encapsulated, 0 % of well-circumscribed, and 52 % of infiltrative fvPTC tumors (p management algorithm for fvPTC.

    This study was designed to compare the efficacy of various treatments intended to synchronise follicular wave cycles in dromedary camels by removing the existing follicle of unknown size and replacing it with a follicle capable of ovulating at a known time. Camels were randomly assigned to one of five groups and treated with either (1) 5mg oestradiol benzoate (i.m.) and 100mg progesterone (i.m.; E/P, n=15), (2) 20 icrog GnRH analogue, buserelin (i.m.; GnRH, n=15), (3) 20 microg buserelin (i.m.) on Day 0 (T=0) and 500 microg prostaglandin on Day T+7 (GnRH/PG n=15), (4) transvaginal ultrasound-guided follicle ablation of all follicles > or =0.5 cm (ABL, n=15) or (5) 5 ml saline (i.m; Controls n=15). All camels were subsequently injected with 20 microg buserelin 14 days after the first treatment was given. The ovarian response was monitored daily by transrectal ultrasonography and the intervals from treatment to follicular wave emergence and also the day on which the new dominant follicle reached 1.3 cm was recorded. Amongst the treatment groups the mean interval from treatment to new follicle wave emergence and treatment to time taken for the new dominant follicle to reach 1.3 cm in diameter was shortest in the ABL group (2.3+/-0.5 days and 8.8+/-1.1 days respectively, P=0.044) and longest in the E/P group (6.4+/-0.8 days and 12.2+/-1.0 days respectively, P or =2.0 cm or follicle regressing groups, therefore fewer of these camels ovulated (ABL n=7; E/P n=9; Control n=6) after GnRH injection on Day T+14. In conclusion, two GnRH injections 14 days apart or two GnRH injections 14 days apart and PG on Day 7 after the first GnRH were the most effective methods to synchronise ovulation rate in dromedary camels at a fixed time interval of 14 days after treatment.

    2015-09-01

    Persistent humoral immunity depends on the follicular B cell response and on the generation of somatically mutated high-affinity plasma cells and memory B cells. Upon activation by an antigen, cognately activated follicular B cells and follicular T helper (TFH ) cells initiate germinal centre (GC) reaction during which high-affinity effector cells are generated. The differentiation of activated follicular B cells into plasma cells and memory B cells is guided by complex selection events, both at the cellular and molecular level. The transition of B cell into a plasma cell during the GC response involves alterations in the microenvironment and developmental state of the cell, which are guided by cell-extrinsic signals. The developmental cell fate decisions in response to these signals are coordinated by cell-intrinsic gene regulatory network functioning at epigenetic, transcriptional and post-transcriptional levels.

    The relationships between oral health conditions, dietary practices and nutritional status, and general health status in the older American are complex, with many interrelating factors. Just as inadequate nutrition can affect oral health, poor oral health status affects food choices and, thus, nutritional status. It is clearly essential that the primary care practitioner and/or screening health professionals always include an evaluation of oral status in assessment of an elderly person. Effective care for the elderly dental patient requires knowledge about the disease of aging and the impact of those diseases on oral health and nutrition, pharmacology and drug interactions and their impact on oral health status, the biology of aging including sensory changes, the relationship of general medicine and systemic diseases, and psychology and sociology. The attitudes of empathy and understanding, caring and compassion, respect and a positive attitude toward the older patient, and flexibility in treatment planning are also critical elements. The interdisciplinary team of physicians, nurses, nutrition professionals, dentists, and social service professionals must all work together to ensure that good oral health status and adequate nutrition are maintained in older Americans. Recognizing and treating oral health and nutrition problems are important in improving the health and quality of life for the elderly population. Research that can provide more answers to health care problems in this growing group; educating professionals with respect to the relationships between oral health and nutrition; and public policy changes with regard to provision and funding of nutrition services, especially when provided by registered and/or licensed nutrition professionals, contribute to improving the health and quality of life for elders.

    The aim of this study was to evaluate the oral sequelae of radiotherapy in patients treated between 1999 and 2003 for head and neck tumors. One-hundred patients (24 women, 76 men) ranging in age from 30 to 83 years (mean 59.2 years) were examined. Time since radiotherapy ranged from 1 to 72 months (mean 28 months). The total mean radiation dose received by the patients was 5,955 cGy. The evaluation protocol included anamnesis, intraoral and extraoral examination, measurement of stimulated salivary flow and salivary pH. Symptoms reported by the patients included dry mouth (68%), dysphagia (38%), and dysgeusia (30%). In 64% of the patients, the mean stimulated salivary flow rate was less than 0.7 ml/min. The mean salivary pH was 6.97 ({+-} 0.714). Stimulated salivary flow increased with increasing postradiotherapy time (p < 0.05). The prevalence of mucositis was associated with higher radiation doses (p < 0.05), and the prevalence of atrophic candidiasis was related to a longer post-treatment period (p < 0.05). Two cases of recurrence of the primary tumor were detected during the study. The main effect of radiotherapy in the head and neck region was a reduction of the salivary flow rate, even though our study demonstrated that there was a modest late improvement of the salivary flow.

    Full Text Available The objectives of the present study were to examine the fatty acid (FA profiles in serum and in the follicular fluid (FF and the association between polyunsaturated fatty acid level (PUFA and follicular growth dynamics following induced luteolysis in dairy cows. A total of 29 dairy cows (CL>25mm, follicle≈15mm at d0 (start of the experiment were submitted to ultrasound guided transvaginal follicular aspiration for FF collection from the largest follicle and were injected with 500 μg of cloprostenol. The cows were subdivided into Group A1 (n=11 and Group A2 (n=8 resuming follicular growth either from a secondary follicle less than or larger than 8.5mm, respectively, present at the moment of aspiration and Group A0 (n=10 not resuming follicular growth. Follicular development was monitored daily by ultrasonography until the next dominant follicle reached ≈15mm and was subsequently punctured in Group A1 and A2 (d1. Serum and FF samples for FA determination were taken at d0 from all cows and at d1 in Group A1 and A2. No differences were observed between the FA profile in serum nor in FF between sampling days. Regarding the PUFA levels, the serum linoleic acid (C18:2n6 levels at d0 and d1 were significantly higher than in FF, while alpha linolenic acid (C18:3n3 was lower in the serum than in FF, both at d0 and d1. At d0, a tendency for negative correlation between serum and the FF C18:2n6 with subsequent daily follicular growth rate was observed, while, at d1 there was a strong negative correlation between the serum C18:2n6 and daily growth rate (r=-0.71; p=0.0006. The present study revealed similarities of the FA profiles in the serum and in the FF and association between serum and FF PUFA content with the follicular dynamics after induced luteolysis.

    Full Text Available The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20 were randomly divided into four groups of five heifers/group. Heifers were given a single dose by i.m. administration of 100 mg Follicle Stimulating Hormone dissolved in polyvinylpyrrolidone (FSHp at 24 h. Ovum pick up (OPU occurred at 72 h (F24O72 protocol; Group 1 or 96 h (F24O96 protocol; Group 2, and at 36 h and OPU at 72 h (F36O72 protocol; Group 3 or 96 h (F36O96 protocol; Group 4 after follicular ablation. The dynamics of ovarian follicular growth were monitored by twice-daily ultrasonographic examinations. Blood sample collections were performed every 12 h after initiation of treatment for assessment of FSH, E2 and P4 profiles. All heifers were subjected to eight repeated sequential sessions of OPU. The follicular deviation commenced 24±5.32 h after follicular ablation in all groups. The circulatory FSH surged quickly from 24 to 36 h (>0.8 ng/ml after follicular ablation and circulatory estrogen levels steadily increased from 36 h until OPU in all groups. At the end of the OPU sessions, the mean number of aspirated follicles/heifer/session in F36O72 protocol (Group 3 and F36O96 protocol (Group 4 were higher than in the two other groups (p<0.05. The number of cumulus-oocyte complexes (COCs, cleaved and day 8 blastocysts rates in the F36O72 protocol (Group 3 were higher than in the other groups (p<0.05. It can be concluded that a single dose i.m. administration of 100 mg FSHp at 36 h and OPU at 72 h after follicular ablation (F36O72 protocol; Group 3 was the most effective protocol for superstimulation of follicular growth for repeated OPU and subsequent in vitro embryo production in Thai native heifers.

  11. Sex of bovine embryos may be related to mothers' preovulatory follicular testosterone.

    Although the sex of the offspring in mammals is commonly viewed as a matter of chance (depending on whether an X or a Y chromosome-bearing spermatozoon reaches the ovum first), evolutionary biologists have shown that offspring sex ratios are often significantly related to maternal dominance, a characteristic that has been shown to be linked to testosterone in female mammals, including humans. Hence, we hypothesized that variations in female testosterone might be related to reproductive mechanisms associated with sex determination, with higher levels of follicular testosterone being associated with a greater likelihood of conceiving a male. To investigate this hypothesis we collected follicular fluid and cumulus-oocyte complexes from bovine antral follicles. Individual matched samples of follicular fluid were assayed for testosterone, whereas the oocytes were matured, fertilized, and cultured in vitro. The resultant embryos were sexed by PCR. The level of testosterone in the follicular fluid was then compared with sex of the embryo (n = 171). Results showed that follicular testosterone levels were significantly higher for subsequently male embryos (Mann-Whitney U = 2823; P [one-tailed] = 0.016). When we excluded embryos from follicles in which the estradiol-to-testosterone ratio was more than 1 (leaving a sample size of 135), the same result held (Mann-Whitney U = 1667; P [one-tailed] = 0.009). Thus, bovine ova that developed in follicular fluid with high concentrations of testosterone in vivo were significantly more likely to be fertilized by Y chromosome-bearing spermatozoa.

    Ovaries, which provide a place for follicular development and oocyte maturation, are important organs in female mammals. Follicular development is complicated physiological progress mediated by various regulatory factors including microRNAs (miRNAs). To demonstrate the role of miRNAs in follicular development, this study analyzed the expression patterns of miRNAs in granulosa cells through investigating three previous datasets generated by Illumina miRNA deep sequencing. Furthermore, via bioinformatic analyses, we dissected the associated functional networks of the observed significant miRNAs, in terms of interacting with signal pathways and transcription factors. During the growth and selection of dominant follicles, 15 dysregulated miRNAs and 139 associated pathways were screened out. In comparison of different styles of follicles, 7 commonly abundant miRNAs and 195 pathways, as well as 10 differentially expressed miRNAs and 117 pathways in dominant follicles in comparison with subordinate follicles, were collected. Furthermore, SMAD2 was identified as a hub factor in regulating follicular development. The regulation of miR-26a/b on smad2 messenger RNA has been further testified by real time PCR. In conclusion, we established functional networks which play critical roles in follicular development including pivotal miRNAs, pathways, and transcription factors, which contributed to the further investigation about miRNAs associated with mammalian follicular development.

    Follicular carcinoma of thyroid is the second most common type of carcinoma of thyroid, and it may metastasize to bone, lung, brain, and skin. However, the initial presentation of follicular carcinoma of the thyroid as a large intrathoracic mass without any symptoms of thyroid gland enlargement and dysfunction is very rare. We hereby report a case of a 50-year-old male who presented with chief complaints of chest and low back pain. Preliminary evaluation led to the provisional diagnosis of left-sided intrathoracic mass with vertebral metastasis which was suspected to be a case of bronchogenic carcinoma with distant metastasis. Surprisingly, transthoracic biopsy and histopathology revealed metastasis from follicular carcinoma of thyroid. This prompted us for a retrograde evaluation for a primary thyroid malignancy for which an ultrasound and contrast enhanced computed tomography (CECT) of the neck was done which confirmed the presence of a solitary thyroid nodule. Ultrasonography-guided fine-needle aspiration cytology of the nodule revealed follicular carcinoma of thyroid. Histopathological evaluation subsequent to total thyroidectomy revealed follicular carcinoma thyroid, further confirming the diagnosis. The patient was then referred to Department of Nuclear Medicine and Radiotherapy for radionuclide ablation and chemotherapy. We chose to report this case because of its rare presentation as a large intrathoracic mass and the retrograde diagnosis of follicular carcinoma of thyroid. To the best of our knowledge, this is the first report of such a rare case.

    The aim of this study was to record the age and body size of 23 captive female hawksbill turtles at the onset of follicular development. The age, straight carapace length (SCL), and body mass (BM) of the turtles were recorded between 2006 and 2014 at follicular development (determined via ultrasonography) these parameters were 17.7 ± 1.7 years (range: 13-20 years), 77.7 ± 3.3 cm (73.3-83.5 cm), and 61.1 ± 8.0 kg (48.2-76.1 kg), respectively. When the year of the onset of follicular development was designated year 0, the increase in SCL in years -7-0 and 0-3 averaged 2.2 cm and 1.0 cm, respectively. Correspondingly, the increase in BM in years -7-0 and 0-3 averaged 5.0 kg and 2.2 kg, respectively. This is the first study to report the age and body size of captive female hawksbill turtles at the onset of follicular development, which indicates the beginning of sexual maturation. The reduction in growth after follicular development suggests that at the onset of sexual maturation, female hawksbills may utilize energy for follicular development rather than growth.

    To assess whether an early GnRH antagonist start leads to better follicular synchronization and an improved clinical pregnancy rate (CPR). A retrospective cohort study. A total of 218 infertile women who underwent IVF between January 2011 and February 2013. The initial cohort (Cohort I) that underwent IVF between January 2011 and March 2012 included a total of 68 attempted IVF cycles. Thirty-four cycles were treated with the conventional GnRH antagonist protocol, and 34 cycles with an early GnRH antagonist start protocol. The second cohort (Cohort II) that underwent IVF between June 2012 and February 2013 included a total of 150 embryo-transfer (ET) cycles. Forty-three cycles were treated with the conventional GnRH antagonist protocol, 34 cycles with the modified early GnRH antagonist start protocol using highly purified human menopause gonadotropin and an addition of GnRH agonist to the luteal phase support, and 73 cycles with the GnRH agonist long protocol. The analysis of Cohort I showed that the number of mature oocytes retrieved was significantly higher in the early GnRH antagonist start cycles than in the conventional antagonist cycles (11.9 vs. 8.2, p=0.04). The analysis of Cohort II revealed higher but non-significant CPR/ET in the modified early GnRH antagonist start cycles (41.2%) than in the conventional antagonist cycles (30.2%), which was comparable to that of the GnRH agonist long protocol cycles (39.7%). The modified early antagonist start protocol may improve the mature oocyte yield, possibly via enhanced follicular synchronization, while resulting in superior CPR as compared to the conventional antagonist protocol, which needs to be studied further in prospective randomized controlled trials.

    We present findings concerning {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET) at end-treatment evaluation in follicular lymphoma (FL) in order to establish possible predictive factors for progression-free survival (PFS) and patient outcome. We retrospectively analysed data from 91 consecutive FL patients (M:F = 51:40, mean age 61) referred to our PET Unit at therapy completion: 38 with an indolent form (grade 1-2) and 53 with an aggressive FL (grade 3a and b) according to the World Health Organization (WHO) classification. A total of 148 FDG PET/CT scans were analysed and findings reported as positive or negative for disease. The overall response to treatment was assessed according to the revised International Workshop Criteria (IWC). The final outcome was defined as remission or disease by taking clinical, instrumental and histological data as standards of reference, with a mean follow-up period of 3 years (range 1-8). A statistical analysis was performed with respect to PFS and patient outcome for FDG PET result, tumour grading, Follicular Lymphoma International Prognostic Index (FLIPI), disease stage and number of relapses, on uni- and multivariate analyses, with p < 0.05 considered as significant. Overall patients presented a mean PFS of 35 months (range 3-86), with a relapse rate of 42%. At final outcome, remission was achieved in 67 of 91 patients (74%). Of the different predictive factors, only FDG PET result significantly correlated with patient outcome (p = 0.0002). PET/CT performance at the end of treatment was as follows: 100% sensitivity, 99% specificity, 89% positive predictive value and 100% negative predictive value. The Kaplan-Meier analysis demonstrated a statistically significant correlation with PFS for FDG PET (p < 0.0001), FLIPI score (0-1 versus {>=}2) (p = 0.0451) and number of relapses (none versus {>=}1) (p = 0.0058). These findings were confirmed at the univariate analysis, whereas at the multivariate analysis only

    Rituximab, a chimeric monoclonal antibody directed against the CD20 antigen, has been shown to be active in newly diagnosed and relapsed patients with follicular lymphoma (FL), both as monotherapy and in combination with chemotherapy. Many studies suggest that the prognosis of patients with FL may improve when it is used in combination with chemotherapy. Despite these advances, the disease remains essentially incurable with standard therapy, and novel approaches to treatment are needed because optimal therapy is not defined. The combination of chlorambucil-rituximab is one of several standard treatment options for FL. Here, we considered data arising from 75 patients with newly diagnosed FL at the European Institute of Oncology treated with the combination of rituximab plus chlorambucil. The aim of this study was to evaluate the efficacy and safety of chlorambucil and rituximab, delivered 6 mg/m(2) /day orally for 6 weeks and 375 mg/m(2) in a standard 4-weekly schedule, respectively. Patients responding to the induction therapy received a prolonged therapy with four additional cycles of chlorambucil plus rituximab. Seventy-one patients (94.6%) completed the treatment; four patients discontinued treatment because of grade 3-4 hematological toxicity. The overall response rate was 97.3% including 74.7% of complete responses. Only two patients had a stable disease at revaluation after treatment. With a median follow-up of 57 months, 72 patients (96%) are alive. Median event-free survival (EFS) and median overall survival (OS) were not reached; 5-year OS rate was 98.4%. The 5-year EFS was 71.3%. By univariate and multivariate analyses, elevated beta-2 microglobulin levels and partial responses to therapy were correlated with worse EFS. These results suggest that the combination of chlorambucil and rituximab is an active and safe regimen in patients with newly diagnosed FL, principally in those with low tumour burden and favourable prognostic factors.

    Many patients with upper airway sleep disorders can be successfully treated with oral appliance therapy. It is necessary for dentists to recognize these patients and refer them to a physician for further evaluation. Dentists must not become the primary care providers for these patients or attempt to treat a medical problem with an oral appliance without a proper diagnosis, which usually requires a sleep study and can only be diagnosed by a physician. Dentists must also be able to treat the patients referred by physicians and to follow accepted procedures when fabricating, inserting, titrating, and providing follow-up care for oral appliance therapy. In addition, the dental community needs to continue to heighten the awareness in their local medical community and in their patient population as to the possible contribution of oral appliance therapy to the management of snoring and some of the sleep-related breathing disorders.

    Full Text Available Histoplasmosis is a systemic fungal disease that takes various clinical forms, among which oral lesions are rare. The disseminated form of the disease that usually occurs in association with Human Immunodeficiency Virus (HIV is one of the AIDS-defining diseases. Isolated oral histoplasmosis, without systemic involvement, with underlying immunosuppression due to AIDS is very rare. We report one such case of isolated oral histoplasmosis in a HIV-infected patient.

    The penetration of topically applied compounds varies considerably in the different regions of the human body. The presence of hair follicles significantly contributes to this effect by an increase in surface area and a disruption of the epidermal barrier towards the lower parts of the hair follicle. The human hair follicle, hereby, serves not only as a reservoir, but also as a major entry point for topically applied compounds. Topical delivery of active compounds to specific targets within the skin may help reduce side-effects caused by unspecific reactions, and may help develop new strategies in the prevention and treatment of skin diseases. Various drug carrier and drug delivery systems are currently being investigated. The aim of these investigational efforts is to direct topically applied compounds to the different types of hair follicles and, ideally, to specific compartments and cell populations within the hair follicles. Follicular targeting offers opportunities for new developments, not only in hair therapy and in the treatment of hair follicle associated diseases but also in gene therapy and immunotherapy.

    Particulate drug carriers e.g. nanoparticles (NPs) have been shown to penetrate and accumulate preferentially in skin hair follicles creating high local concentration of a drug. In order to develop such a follicle targeting system we obtained and characterized solid lipid nanoparticles (SLN) loaded with roxithromycin (ROX). The mean particle size (172±2 nm), polydisperisty index (0.237±0.007), zeta potential (-31.68±3.10 mV) and incorporation efficiency (82.1±3.0%) were measured. The long term stability of ROX-loaded SLN suspensions was proved up to 26 weeks. In vitro drug release study was performed using apparatus 4 dialysis adapters. Skin irritation test conducted using the EpiDerm™ tissue model demonstrated no irritation potential for ROX-loaded SLN. Ex vivo human skin penetration studies, employing rhodamine B hexyl ester perchlorate (RBHE) as a fluorescent dye to label the particles, revealed fluorescence deep in the skin, specifically around the hair follicles up to over 1mm depth. The comparison of fluorescence intensities after application of RBHE solution and RBHE-labelled ROX-loaded SLN was done. Then cyanoacrylate follicular biopsies were obtained in vivo and analyzed for ROX content, proving the possibility of penetration to human pilosebaceous units and delivering ROX by using SLN with the size below 200 nm.

  5. Autologous and allogeneic hematopoietic stem cell transplantation in follicular lymphoma.

    High-dose chemotherapy and autologous stem cell transplantation (ASCT) improve survival in follicular lymphoma; however, relapse remains the most common cause of death. The lower risk of relapse with allogeneic SCT (alloSCT) is offset by a high transplant-related mortality (TRM). English articles indexed in the MEDLINE database were reviewed to discuss the role of graft purging, rituximab maintenance after ASCT, reduced-intensity conditioning (RIC) alloSCT, T-cell depletion, donor lymphocyte infusion (DLI) and alternate donor sources. Optimal salvage consolidation strategy may utilize ASCT following non-total body irradiation-based conditioning regimen in second remission. Rituximab maintenance after ASCT may improve molecular remission but is not yet shown to improve overall survival. RIC alloSCT permits its use in older and less-fit patients. Studies with T-cell depleted graft failed to reduce TRM despite a decline in graft-versus-host disease; however, these studies did demonstrate a therapeutic role of DLI in post-transplant relapses. In recent years, haploidentical and umbilical cord blood donors have emerged as alternative donor sources, with outcomes comparable to matched unrelated donor SCT. In the future, incorporation of novel therapeutic agents, improved risk-adapted treatment strategies, and advancement of transplant techniques may provide a better chance of survival.

  6. Follicular lymphoma (FL): Immunological tolerance theory in FL.

    García-Muñoz, Ricardo; Panizo, Carlos

    2017-02-01

    The ultimate cause of follicular lymphoma (FL) remains unknown. Remarkably, almost nothing is known about immunological tolerance mechanisms that might contribute to FL development. Immunological tolerance mechanisms, like other stimuli, also induce persistent changes of B cell receptors that induce genetic instability and molecular aberrations promoting the development of a neoplasm. Using the same method as Burnet, we provide a new perspective taking advantage of the comparison of a normal linear B cell differentiation process and FL development within the framework of clonal selection theory. We propose that FL is a malignancy of cells that acquire both translocation t(14;18) and self-BCR, inducing them to proliferate and mature, resistant to negative selection. Additional genetic damage induced by non-apoptotic tolerance mechanisms, such as receptor editing, may transform a self-reactive B cell with t(14;18) into an FL. The result of tolerogenic mechanisms and genetic aberrations is the survival of FL B cell clones with similar markers and homogenous gene expression signatures despite the different stages of maturation at which the molecular damage occurs. To antagonize further growth advantage due to self-antigen recognition and chronic activation of tolerance mechanisms in the apoptosis-resistant background of FL B cells, inhibitors of BCR signaling may be promising therapeutic options.

  7. Follicular helper T cell in immunity and autoimmunity

    Directory of Open Access Journals (Sweden)

    D. Mesquita Jr

    2016-01-01

    Full Text Available The traditional concept that effector T helper (Th responses are mediated by Th1/Th2 cell subtypes has been broadened by the recent demonstration of two new effector T helper cells, the IL-17 producing cells (Th17 and the follicular helper T cells (Tfh. These new subsets have many features in common, such as the ability to produce IL-21 and to express the IL-23 receptor (IL23R, the inducible co-stimulatory molecule ICOS, and the transcription factor c-Maf, all of them essential for expansion and establishment of the final pool of both subsets. Tfh cells differ from Th17 by their ability to home to B cell areas in secondary lymphoid tissue through interactions mediated by the chemokine receptor CXCR5 and its ligand CXCL13. These CXCR5+ CD4+ T cells are considered an effector T cell type specialized in B cell help, with a transcriptional profile distinct from Th1 and Th2 cells. The role of Tfh cells and its primary product, IL-21, on B-cell activation and differentiation is essential for humoral immunity against infectious agents. However, when deregulated, Tfh cells could represent an important mechanism contributing to exacerbated humoral response and autoantibody production in autoimmune diseases. This review highlights the importance of Tfh cells by focusing on their biology and differentiation processes in the context of normal immune response to infectious microorganisms and their role in the pathogenesis of autoimmune diseases.

    Antibody responses to malaria and candidate malaria vaccines are short-lived in children, leaving them susceptible to repeated malaria episodes. Because T follicular helper (TFH) cells provide critical help to B cells to generate long-lived antibody responses, they have become the focus of recent studies of Plasmodium-infected mice and humans. The emerging data converge on common themes, namely, that malaria-induced TH1 cytokines are associated with the activation of (i) T-like memory TFH cells with impaired B cell helper function, and (ii) pre-TFH cells that acquire Th1-like features (T-bet expression, IFN-γ production), which impede their differentiation into fully functional TFH cells, thus resulting in germinal center dysfunction and suboptimal antibody responses. Deeper knowledge of TFH cells in malaria could illuminate strategies to improve vaccines through modulating TFH cell responses. This review summarizes emerging concepts in TFH cell responses to malaria. Copyright © 2016. Published by Elsevier Ltd.

    Full Text Available Follicular thyroid carcinoma (FTC is a well-differentiated tumor which resembles the normal microscopic pattern of the thyroid. Although intracranial metastasis to the brain is frequent in adults, metastasis from FTC is very rare. Dural metastases mimicking meningioma have been documented in the literature now and then. However, cases arising from a FTC are again very rare. We report the case of a middle-aged lady who presented with progressive, painless left eye proptosis. She was noted to have a non-axial proptosis with dystopia, compressive optic neuropathy and exposure keratitis. She also had a painless swelling over the occipital region. She was initially misdiagnosed to have multiple foci of meningioma based on magnetic resonance imaging findings. Subsequent histopathological examination revealed presence of FTC. She was euthyroid but was found to have multiple small thyroid nodules by ultrasonography. Hence, the definite diagnosis of all dural masses must be histological wherever possible and thyroid carcinoma should be considered as a potential primary tumour in such presentations.

  13. Pituitary down-regulation and follicular synchronization%降调节与卵泡发育同步化

    2011-01-01

    The key aim of pituitary down-regulation in controlled ovarian stimulation (COS) is to prevent premature endogenous luteinizing hormone (LH) surge. The down-regulation protocols include long and short GnRH agonist protocols, as well as GnRH antagonist protocol. The long GnRH agonist protocol starting in the midluteal phase of the preceding cycle give the best IVF results with regard to oocyte yield and pregnancy rates. This long protocol induces profound suppression of endogenous release of gonadotrophins during the early follicular phase, allowing the antral follicles to grow coordinately in response to exogenous gonadotrophins to accomplish simultaneous maturation. The short and GnRH antagonist protocols can abridge the duration and complexity of COS and improve patient compliance as compared with the reference long protocol for IVF. Nevertheless, the explanation for the poor IVF-ET outcome achieved with these two protocols compared with long protocol could be, at least in part, related to pre-existing asychronization of early antral follicles before the start of gonadotrophin administration. The steroid (oral contraceptive pill (OCP), synthetic progestogen and natural estrogen) pre-treatment and GnRH-antagonist pre-treatment may be useful to suppress luteal FSH and reduce size differences among FSH-sensitive follicles during the early follicular phase. These approaches represent potential alternatives to synchronize multi-follicular development and improve ovarian stimulation results. However, larger studies are needed to confirm whether follicular growth coordination induced by steroids and premenstrual GnRH antagonist pre-treatment improve IVF-ET pregnancy rates with GnRH antagonist or short agonist protocols.%控制性卵巢刺激(COS)中垂体降调节的主要作用是预防早发内源性黄体生成素(LH)峰.降调节方案包括有促性腺激素释放激素激动剂(GnRH-a)长、短方案,以及GnRH拮抗剂(GnRH-ant)方案等.于前一周期黄体中

    The RET proto-oncogene encodes a receptor tyrosine kinase for transforming growth factor-beta-related neurotrophic factors, which include GDNF and neurturin. The expression of RET proto-oncogene was detected in several tissues, such as spleen, thymus, lymph nodes, salivary gland, and spinal cord, and in several neural crest-derived cell lines. RET expression in the thyroid gland was reported to be restricted to neural crest-derived C cells. The presence of RET mRNA or protein has not yet been reported in thyroid follicular cells. We previously demonstrated the expression of oncogenic rearranged versions of RET in papillary thyroid carcinomas: tumors derived from thyroid follicular cells. To assess the expression of the normal RET proto-oncogene in follicular cells, we analyzed its expression in a panel of neoplasias originating from thyroid follicular epithelial cells: papillary carcinomas and both follicular adenomas and carcinomas. We also demonstrated the presence of RET normal transcripts in two follicular thyroid carcinoma lymph node metastases. Moreover, we found the presence of the RET/ELE1 transcript, the reciprocal complementary form of the oncogenic fusion transcript ELE1/RET, in a papillary thyroid carcinoma specimen expressing the RET/PTC3 oncogene, thus demonstrating that the RET promoter is active in those cells after rearrangement. Finally, we show that in a papillary carcinoma-derived cell line expressing the proto-RET receptor and the related GFRalpha2 co-receptor, GDNF treatment induced RET tyrosine phosphorylation and subsequent signal transduction pathway, indicating that RET could be active in thyroid follicular cells.

    Full Text Available The experiment was conducted on 30 Holstein-Friesian cows: 10 cows in the follicular phase of the cycle and in the luteal phase 10 d later, 10 cows with follicular cysts, and 10 with luteal cysts. The presence of the ovarian structures was confirmed by ultrasonography. Serum levels of progesterone and 17β-oestradiol were tested with ELISA. Samples for cytological examination were collected from the uterus of all cows using a cytological brush. Following staining, the smears were evaluated in terms of quality and percentages of endometrial cells. In the follicular phase of the oestrous cycle, cells of type A - superficial cells (64.6 ± 4.48 were proportionally the largest group of cells. Cells of type C - basal cells (19.8 ± 2.75 were also present. In the luteal phase, the highest percentage of cells was of type B - intermediate cells (76.9 ± 4.26. When follicular cysts were present on the ovaries, the cytology resembled the follicular phase of the cycle, but with many younger type C cells (33.1 ± 4.11. In the case of luteal cysts on the ovaries, the cytology was similar to that of the luteal phase of the cycle, however with a lower percentage of type B cells (58.1 ± 5.71, and a slightly higher percentage of the other types. The differences in the cytological image of the uterus when different ovarian structures are present, depend on the hormonal activity of those structures. Due to the lack of literature data, the results of the study are important as a model, and may substantially facilitate identification of phases of the oestrus cycle, or the pathologies described, as well as indicate the current status of the endometrium

    The objective of this experiment was to examine the effects of varying the interval from follicular wave emergence to progestin (controlled internal drug-releasing insert, CIDR) withdrawal on follicular dynamics and the synchrony of estrus. A secondary objective was to assess the effects of causing the dominant follicle (DF) to develop in the presence or absence of a corpus luteum (CL) on follicular dynamics and the synchrony of estrus and ovulation. The experiment was designed as a 2 x 2 x 2 factorial arrangement of treatments with injection of GnRH or estradiol-17 beta and progesterone (E2 + P4) at treatment initiation, duration of CIDR treatment, and injection of PG (prostaglandin F2 alpha) or saline at the time of CIDR insertion as main effects. Estrous cycles (n = 49) in Angus cows were synchronized, and treatments commenced on d 6 to 8 of the estrous cycle. Cows were randomly assigned to receive a CIDR containing 1.9 g of P4 for 7 or 9 d. Approximately half the cows from each CIDR group received either GnRH (100 micrograms) or E2 + P4 (1 mg of E2 + 100 mg of P4) at CIDR insertion. Cows in GnRH or E2 + P4 groups were divided into those that received PG (37.5 mg) or saline at CIDR insertion. All cows received PG (25 mg) 1 d before CIDR removal. Daily ovarian events were monitored via ultrasound. The intervals from GnRH or E2 + P4 treatment to follicular wave emergence were 1.4 and 3.3 d, respectively (P 0.05). Altering the interval from follicular wave emergence to progestin removal or creating different luteal environments in which the DF developed caused differences in the size of the DF at CIDR removal and the timing of the onset of estrus, but it did not affect the synchrony of estrus or ovulation.

    2015-02-01

    Full Text Available Background: Follicular thyroid cancer (FTC metastasizes most commonly to the lungs and non-cranial bones. Skull and skin are uncommon sites and usually manifest well after the diagnosis of primary malignancy. Metastasis to skull and skin as the presenting feature of FTC is infrequently reported in the literature. Case presentation: A 65-year-old Caucasian woman with a history of thyroid nodule presented with the complaint of rapidly growing skull nodules which had been present for 3 years but were stable previously. She denied any fevers, chills, history of trauma, or weight loss. She denied any history of smoking or head and neck irradiation. On physical examination, she had two non-tender gray cystic lesions – one on her left temporal region and the other on the right parietal region. Biopsy was consistent with metastatic FTC. Magnetic resonance imaging of the brain demonstrated 7.1×3.8 cm and 3.7×4.5 cm fairly homogeneous, enhancing, relatively well-defined masses centered in the posterior and left anterior lateral calvarium with intracranial and extracranial extensions but without any vasogenic edema or mass effect on the brain. Thyroid ultrasound showed numerous nodules in both lobes. The patient underwent a total thyroidectomy. Histopathological studies of the thyroid gland revealed a well-differentiated FTC in the left lobe. Then she underwent resection of the tumor in multiple stages. She did not have any recurrence of the FTC or metastases during the follow-up period and will be receiving radioactive iodine treatment. Conclusion: Bone and lung are the common sites of metastasis from FTC, but involvement of skull or skin is unusual, particularly as the presenting feature. Metastases from FTC should be in the differential of patients with new osteolytic hypervascular skull lesions or cutaneous lesions in head and neck area.

  20. Memory T follicular helper CD4 T cells

    2015-02-01

    Full Text Available T follicular helper (Tfh cells are the subset of CD4 T helper cells that are required for generation and maintenance of germinal center reactions and the generation of long-lived humoral immunity. This specialized T helper subset provides help to cognate B cells via their expression of CD40 ligand, IL-21, IL-4, and other molecules. Tfh cells are characterized by their expression of the chemokine receptor CXCR5, expression of the transcriptional repressor Bcl6, and their capacity to migrate to the follicle and promote germinal center B cell responses. Until recently, it remained unclear whether Tfh cells differentiated into memory cells and whether they maintain their Tfh commitment at the memory phase. This review will highlight several recent studies that support the idea of Tfh-committed CD4 T cells at the memory stage of the immune response. The implication of these findings is that memory Tfh cells retain their capacity to recall their Tfh-specific effector functions upon reactivation to provide help for B cell responses and play an important role in prime and boost vaccination or during recall responses to infection. The markers that are useful for distinguishing Tfh effector and memory cells, as well as the limitations of using these markers will be discussed. Tfh effector and memory generation, lineage maintenance, and plasticity relative to other T helper lineages (Th1, Th2, Th17, etc will also be discussed. Ongoing discoveries regarding the maintenance and lineage stability versus plasticity of memory Tfh cells will improve strategies that utilize CD4 T cell memory to modulate antibody responses during prime and boost vaccination.

    Prenatal testosterone (T) excess leads to reproductive dysfunctions in sheep with obesity exaggerating such defects. Developmental studies found ovarian reserve is similar in control and prenatal T sheep at fetal day 140, with prenatal T females showing increased follicular recruitment and persistence at 10 months of age (postpubertal). This study tested if prenatal T sheep show accelerated depletion prepubertally and if depletion of ovarian reserve would explain loss of cyclicity in prenatal T females and its amplification by postnatal obesity. Stereological examinations were performed at 5 (prepubertal, control and prenatal T) and 21 months (control, prenatal T and prenatal T obese, following estrus synchronization) of age. Obesity was induced by overfeeding from weaning. At 5 months, prenatal T females had 46% less primordial follicles than controls (P obesity did not exaggerate the impact of prenatal T on follicular recruitment indicating that compounding effects of obesity on loss of cyclicity females is not due to depletion of ovarian reserve. Assessment of follicular dynamics across several time points during the reproductive life span (this and earlier study combined) provides evidence supportive of a shift in follicular dynamics in prenatal T females from one of accelerated follicular depletion initiated prior to puberty to stockpiling of growing follicles after puberty, a time point critical in the development of the polycystic ovary syndrome phenotype.

    BACKGROUND The ovarian follicular basal lamina underlies the epithelial membrana granulosa and maintains the avascular intra-follicular compartment. Additional layers of basal lamina occur in a number of pathologies, including pili annulati and diabetes. We previously found additional layers of follicular basal lamina in a significant percentage of healthy bovine follicles. We wished to determine if this phenomenon existed in humans, and if it was related to oocyte function in the bovine. METHODS AND RESULTS We examined follicles from human ovaries (n = 18) by electron microscopy and found that many follicles had additional layers of basal lamina. Oocytes (n = 222) from bovine follicles with normal or unusual basal laminas were isolated and their ability to undergo in vitro maturation, fertilization and culture to blastocyst was compared. Healthy bovine follicles with a single layer of basal lamina had oocytes with significantly (P < 0.01) greater developmental competence than healthy follicles with additional layers of follicular basal lamina (65% versus 28%). CONCLUSIONS These findings provide direct evidence that the phenotype of the follicular basal lamina is related to oocyte competence. PMID:19095662

    Introduction Ameloblastoma holds a unique position among benign tumours by its locally destructive and invasive nature. Recently improvised molecular techniques helped researchers to unravel the myth behind such biologic behaviour. Though interesting findings have been delivered, the rhythmic correlation regarding the exact mechanism still remains lacking. Neurotrophins and their receptor mediated pathways play a crucial role in survival, death and differentiation of many neuroectoderm derived cells. With this background, the study has been aimed to investigate the expression of p75-NTR (Neurotrophin Receptor) in follicular and plexiform ameloblastoma. Aim To analyze the immunohistochemical expression pattern of p75-NTR in ameloblastoma and to compare the immunohistochemical expression pattern of p75-NTR among the histological types of ameloblastoma, follicular and plexiform patterns. Materials and Methods Total 22 ameloblastomas (12 follicular, 10 plexiform) were immuno-stained with anti-human p75-NTR mouse IgG monoclonal antibody and the pattern of staining is statistically analyzed. Results Only 11 (10 follicular, 1 plexiform) out of 22 ameloblastomas showed immuno-reactivity to p75-NTR. In ameloblastoma, only the peripheral pre-ameloblast like tall columnar cells showed reactivity whereas the stellate reticulum-like cells were immuno-negative. The staining pattern was membranous in the immuno-reactive cells. The results were studied with the downstream pathways from the literature and a possible mechanism has been proposed. Conclusion The expression pattern of p75-NTR was found to be more in follicular ameloblastoma than plexiform. PMID:27656566

    Full Text Available Aim: Estimation of some biochemical constituents in follicular fluid of non-descript cows of Assam. Materials and Methods: Twenty five pairs of ovaries were collected from local slaughter house and the follicular fluid was aspirated from small (2-4 mm, medium (4-6 mm and large (6-9 mm follicles. Aspirated fluid samples were centrifuged at 4000 rpm for 20 min in a refrigerated centrifuge to remove granulosa cells and other cell debris. Supernatant was used for estimation of glucose, total protein, cholesterol, acid phosphatase and alkaline phosphatase. Data generated in the study were analyzed statiscally by SPSS (version 16.0. SPSS South Asia Pvt. Limited, Kacharakanahalli, Bangalore, 560043. Results: A non significant difference was recorded in case of total protein and cholesterol of follicular fluid of small, medium and large sized follicles of cow. However, the glucose level significantly (p<0.01 increased with the increase of follicular size where as the activity of acid phosphatase and alkaline phosphatase significantly (p<0.01 decreased with increase of size. Conclusion: Certain biochemical constituents and enzyme activities of follicular fluid changes with the growth of follicles in non-descript cows of Assam. The glucose concentration increased with the growth of the follicles while acid phosphatase and alkaline phosphatase levels had an inverse relation with the size of the ovarian follicles.

    Full Text Available Purpose: Neoplasms of the thyroid gland are classified according to the cells they originate from and commonly develop from cells of follicular origin. The most common differentiated thyroid cancers (DTC are papillary and follicular carcinomas. Coexistence of two different histological types of primary follicular thyroid neoplasm is a rare condition. There are previous reports of concomitant medullary and papillary thyroid cancers. However, there is scarce data about the simultaneous occurrence of the two different histological types of primary follicular thyroid tumors and this is the first study on that subject. Material and Method: From January 2007 to September 2014, our institutional database was reviewed for patients who underwent thyroid surgery for various indications. Medical records and cytopathology reports of those patients were examined retrospectively. Simultaneous neoplasms of follicular origin were noted. Results: A total of 3.700 patients were operated. Histopathological examination revealed a benign pattern in 2.686 (73% patients and a malignant pattern in 1.014 (27% patients. Among the patients with the diagnosis of DTC, only 20 (1.9% had a concomitant neoplasm within the same thyroid gland. Discussion: Such simultaneous tumors may be a part of a familial tumor syndrome or an unidentified novel gene mutation playing role in the pathogenesis of more than one type of tumor. Based on the current evidence, the synchronous occurrence of those neoplasms in a given patient is likely coincidental in the literature. Further studies on larger patient population with standardized genetic characterization are needed.

    Our understanding of the post-transcriptional mechanisms involved in follicular atresia is limited; however, an important development has been made in understanding the biological regulatory networks responsible for mediating follicular atresia. MicroRNAs have come to be seen as a key regulatory actor in determining cell fate in a wide range of tissues in normal and pathological processes. Profiling studies of miRNAs during follicular atresia and development have identified several putative miRNAs enriched in apoptosis signaling pathways. Subsequent in vitro and/or in vivo studies of granulosa cells have elucidated the functional role of some miRNAs along with their molecular pathways. In particular, the regulatory roles of some miRNAs have been consistently observed during studies of follicular cellular apoptosis. Continued work should gradually lead to better understanding of the role of miRNAs in this field. Ultimately, we expect this understanding will have substantial benefits for fertility management at both the in vivo or/and in vitro levels. The stable nature of miRNA holds remarkable promise in clinical use as a diagnostic tool and in reproductive medicine to solve the ever-increasing fertility problem. In this review, we summarize current knowledge of the involvement of miRNAs in follicular atresia, discuss the challenges for further work and pinpoint areas for future research. PMID:28208755

    2009-03-01

    Over the past 3 decades, fine needle aspiration (FNA) has developed as the most accurate and cost-effective initial method for guiding the clinical management of patients with thyroid nodules. Thyroid FNA specimens containing follicular-patterned lesions are the most commonly encountered and include various forms of benign thyroid nodules, follicular carcinomas, and the follicular variant of papillary thyroid carcinoma. Based primarily upon the cytoarchitectural pattern, FNA is used as a screening test for follicular-patterned lesions to identify the majority of patients with benign nodules who can be managed without surgical intervention. The terminology and reporting of thyroid FNA results have been problematic due to significant variation between laboratories, but the recent multidisciplinary NCI Thyroid FNA State of the Science Conference has provided a seven-tiered diagnostic solution. A key element of this approach is the category "atypical cells of undetermined significance" (ACUS) which is used for those aspirates which cannot be easily classified as benign, suspicious, or malignant. Lesions in this category represent approximately 3-6% of thyroid FNAs and have a risk of malignancy intermediate between the "benign" category and the "suspicious for a follicular neoplasm" category. The recommended follow-up for an ACUS diagnosis is clinical correlation and in most cases, repeat FNA sampling.

    Full Text Available It is known that exposing cell lines in vitro to parabolic flights changes their gene expression and protein production patterns. Parabolic flights and spaceflight in general are accompanied by transient hypergravity and vibration, which may impact the cells and therefore, have to be considered too. To estimate the possible impact of transient hypergravity and vibration, we investigated the effects of these forces separately using dedicated ground-based facilities. We placed follicular thyroid ML-1 and CGTH W-1 cancer cells in a specific centrifuge (MuSIC Multi Sample Incubator Centrifuge; SAHC Short Arm Human Centrifuge simulating the hypergravity phases that occur during one (P1 and 31 parabolas (P31 of parabolic flights, respectively. On the Vibraplex device, the same cell lines were treated with vibration waves corresponding to those that occur during a whole parabolic flight lasting for two hours. After the various treatments, cells were harvested and analyzed by quantitative real-time PCR, focusing on the genes involved in forming (ACTB, MYO9, TUBB, VIM, TLN1, and ITGB1 and modulating (EZR, RDX, and MSN the cytoskeleton, as well as those encoding growth factors (EGF, CTGF, IL6, and IL8 or protein kinases (PRKAA1 and PRKCA. The analysis revealed alterations in several genes in both cell lines; however, fewer genes were affected in ML-1 than CGTH W-1 cells. Interestingly, IL6 was the only gene whose expression was changed in both cell lines by each treatment, while PKCA transcription remained unaffected in all experiments. We conclude that a PKCa-independent mechanism of IL6 gene activation is very sensitive to physical forces in thyroid cells cultured in vitro as monolayers.

    Full Text Available Objective. Thyroid cancer is the most common endocrine malignancy and fastest increasing of all cancers in both men and women in the United States. Traditionally, differentiated thyroid cancer (DTC carries a good prognosis when diagnosed early, but increasingly patients are presenting with late-stage disease and bone metastasis which carries a poor prognosis. Treatment of DTC involves surgical resection followed by radioactive iodine (RAI, which conventionally is thought to reach maximal effectiveness between 6 and 12 months following treatment. We report a case and review the literature surrounding long-term effect of radioactive iodine treatment in metastatic thyroid carcinoma. Methods. Patient clinical encounter and the literature review. Results. We describe a 49-year-old woman with symptomatic metastatic follicular thyroid cancer (FTC to the spine and radiographic evidence of spinal cord compression who was effectively treated with RAI. Her initial serum thyroglobulin (Tg levels following total thyroidectomy were 1,343 ng/mL which dramatically dropped to less than 100 ng/mL following RAI. Forty-three months following treatment with RAI, she has experienced complete resolution of her symptoms and continues to maintain persistently low-thyroglobulin levels of less than 100 ng/mL. Conclusions. RAI is believed to reach peak efficacy within 6–12 months; however, little has been reported regarding the long-term duration of benefit. This case demonstrates that the benefits of RAI therapy may be enduring, even in patients with widely metastatic thyroid cancer. It suggests in clinically stable patients with declining thyroglobulin after treatment, that there may not be an immediate need for additional therapy as RAI treatment may provide lasting effects.

    A 44-year-old female presented to her general dentist with the chief complaint of a painful mouth sore of 2 weeks duration. Clinical examination revealed an irregularly shaped ulcer of the buccal and lingual attached gingiva of the anterior mandible. A biopsy was performed and microscopic evaluation revealed histoplasmosis. Histoplasmosis, caused by Histoplasma capsulate, is the most common fungal infection in the United States. Oral lesions of histoplasmosis are generally associated with the disseminated form of histoplasmosis and may present as a fungating or ulcerative lesion of the oral mucosa. The histologic findings and differential diagnosis for oral histoplasmosis are discussed.

    Full Text Available Clinical oral Candida infection (candidiasis is one of the common oral mucosal infections, and its management is usually frustrating due to either treatment failure or recurrence. Historically, oral candidiasis has been branded as disease of diseased. The unsuccessful management of oral candidiasis can due to either incorrect diagnosis, failure to identify (or correct the underlying predisposing factor(s, or inaccurate prescription of antifungal agents. Failure to properly treat oral candidiasis will lead to persistence of the fungal cell in the oral cavity and hence recurrence of infection. The oral health care provider should be aware of these fall pits in order to successfully manage oral candidiasis.

    Multilocular thymic cysts are rare and acquired lesions induced by an inflammatory arising within the thymus. We report a rare case of multilocular thymic cyst with follicular lymphoid hyperplasia in a 59-year-old female. Chest CT and MRI revealed a large multilocular cystic mass, which contains thick septa and nodules in the thymus. F-18 FDG PET/CT showed almost no FDG uptake of the multilocular cystic mass but moderate FDG uptake of the solid nodules. Extended total thymectomy was performed. Histopathological findings revealed follicular lymphoid hyperplasia of thymic tissue but no neoplastic lesion. Based on these findings, diagnosis of multilocular thymic cyst with follicular lymphoid hyperplasia was made. This is a rare case that preoperatively was difficult to diagnose.

    To investigate whether follicular fluid lipid-soluble micronutrients are associated with embryo morphology parameters during IVF. Follicle fluid and oocytes were obtained prospectively from 81 women. Embryo morphology parameters were used as surrogate markers of oocyte health. HDL lipids and lipid-soluble micronutrients were analyzed by high-pressure liquid chromatography. Non-parametric bi-variate analysis and multivariable ordinal logistic regression models were employed to examine associations between biochemical and embryo morphology parameters. Follicular fluid HDL cholesterol (r = -0.47, p fragmentation. Ordinal logistic regression models indicate that a 0.1 mumol/L increase in beta-cryptoxanthine, adjusted for gamma-tocopherol, is associated with a 75% decrease in the cumulative odds of higher embryo fragmentation (p = 0.010). Follicular fluid HDL micronutrients may play an important role in the development of the human oocyte as evident by embryo fragmentation during IVF.

Three groups of guinea pigs (n=12) were administrated subcutaneously with saline, 20 or 50 IU of eCG, respectively, on cyclic Day 12 (Day 1=vaginal openings). Ovaries were collected at 4 and 8 d after administration (6 animals per group each time). The eCG administration induced significant and distinct morphological changes in the ovaries, as it promoted the luteinization of granulosa cells, but not follicular development. In addition, proliferating cell nuclear antigen (PCNA) and steroidogenic acute regulatory protein (StAR) were immunolocalized specifically in luteinized follicles. Our experiments together indicate that eCG administration can induce follicular luteinization but not superovulation in guinea pigs. The eCG in cyclic guinea pigs functions similar to that of luteinizing hormone (LH), but not follicle-stimulating hormone (FSH).

    Immunohistochemical markers (IGF-1, IGF-1R, VEGF, FGF-2, RARα and RXR) were evaluated in healthy canine thyroid glands (n=8) and in follicular-compact (n=8) and compact thyroid carcinomas (n=8). IGF-1, IGF-1R and VEGF expression was higher in fibroblasts and endothelial cells of compact carcinoma than in healthy glands (P < 0.05). Compared to follicular-compact carcinoma, compact carcinoma had higher IGF-1R expression in fibroblasts, and higher FGF-2 expression in endothelial cells (P < 0.05). RARα expression was higher in endothelial cells of compact carcinoma than in those of other groups (P < 0.05). The upregulation of these proliferation- and angiogenesis-related factors in endothelial cells and/or fibroblasts and not in follicular cells of compact carcinoma compared to healthy glands supports the relevance of stromal cells in cancer progression.

    Localized pemphigus foliaceus (PF) clinically presents as red plaques with scale and crust due to acantholysis of the epidermis. The follicular infundibulum shows acantholysis, but usually with epidermal acantholysis or at least erosion. Localized PF exclusively involving the follicular infundibulum, which shows a peau d'orange appearance, has never been reported. We describe a patient with a red plaque and peau d'orange appearance on the cheek for 20 years. Dyskeratotic acantholysis in the follicular infundibulum was overlooked when the first biopsy specimen was obtained, and a disseminated lesion developed soon after, which led to the diagnosis. Although a peau d'orange appearance is a rare clinical manifestation of PF, PF should be considered as the differential diagnosis on the basis of this appearance, especially when the lesion persists on the face for long periods.

    Migrating pulmonary lesions in children are uncommon, and most are caused by eosinophilic lung disease and parasite, fungus, and tuberculosis infections. A 12-year-old boy was referred to our hospital because of an abnormal chest x-ray. Serial computed tomography scans performed over several months showed a migrating pulmonary consolidation in the left lung, although the patient remained asymptomatic. Finally, surgical biopsy was performed and follicular bronchiolitis was diagnosed. The consolidation disappeared 17 months later without treatment, and the patient has remained asymptomatic. Primary follicular bronchiolitis could be considered as one of the differential diagnosis in patients with pulmonary reticulo-nodular consolidation. It should also be noted that follicular bronchiolitis can migrate. Pediatr Pulmonol. 2017;52:E22-E25. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  1. [Oral candidiasis: clinical features and control].

    Candidiasis is the most commonly encountered fungal infection, and oral candidiasis is often observed as a local opportunistic infection. Oral candidiasis is clinically divided into three types: acute forms, chronic forms, and Candida-associated lesions. Candida adhesion and multiplication are largely regulated by the local and systemic factors of the host. The local factors include impairment of the oral mucosal integrity, which is usually impaired by hyposalivation, anticancer drugs/radiation for head and neck cancers, denture wearing, a decrease in the oral bacterial population, and poor oral hygiene. Among Candida species, oral candidiasis is mostly caused by Candida albicans (C. albicans), C. glabrata, or C. tropicalis. Oral Candida induces a variety of symptoms, such as oral mucosal inflammation manifesting as an uncomfortable feeling, pain, erythema, erosion, taste abnormalities, and hyperplasia of the oral mucosa. Candida overgrowth in the oral cavity may disseminate to distant organs. Therefore, in order to avoid the sequelae of systemic candidiasis, oral candidiasis should be rapidly controlled. Oral candidiasis is usually treated by the local application of antifungal drugs. However, oral candidiasis occasionally escapes the control of such local treatment due to the development of multi-drug resistant Candida strains and species or due to the suppression of salivation or cellular immune activity. When drug-resistant strains are suspected as the pathogens and when the host is generally compromised, the oral administration of combinations of antifungal drugs, enhancement of cellular immune activity, and improvement of the nutritional condition are recommended.

    Lichen planus is an immunologically mediated mucocutaneous disease that is triggered by varied etiological agents. The oral lichenoid reaction is considered a variant of the disease that needs to be clearly diagnosed as a separate entity from oral lichen planus and treated. They follow a strict cause-effector relationship, protocols that suggest the differentiation. Lichen planus has varied clinical forms in the oral mucosa and cutaneously that has different prognosis. This condition also arises in association with various other systemic conditions such as hypertension, diabetes mellitus. There have been cases reported in the esophagus, larynx, scalp, nail, cutaneous areas, especially arms and wrists, trunk. There is reported malignant transformation that essentiates careful examination, treatment protocol and regular follow-up sessions. This article throws light on the disease condition of oral lichen planus and oral lichenoid reaction that is essential for the differentiation and treatment.

    The influence of menstrual cycle phase and oral contraceptive use on neurobehavioral function and circadian rhythms were studied in healthy young women (n = 25) using a modified constant routine procedure during 24 h of sleep deprivation. Alertness and performance worsened across sleep deprivation and also varied with circadian phase. Entrained circadian rhythms of melatonin and body temperature were evident in women regardless of menstrual phase or oral contraceptive use. No significant difference in melatonin levels, duration, or phase was observed between women in the luteal and follicular phases, whereas oral contraceptives appeared to increase melatonin levels. Temperature levels were higher in the luteal phase and in oral contraceptive users compared to women in the follicular phase. Alertness on the maintenance of wakefulness test and some tests of cognitive performance were poorest for women in the follicular phase especially near the circadian trough of body temperature. These observations suggest that hormonal changes associated with the menstrual cycle and the use of oral contraceptives contribute to changes in nighttime waking neurobehavioral function and temperature level whereas these factors do not appear to affect circadian phase.

    Objective: To observe the enzymolysis of digestive enzymes on the native type Ⅱ collagen ( N-C Ⅱ ) and the denatured type Ⅱ collagen (D-c Ⅱ ) in vitro and in vivo in order to study the mechanism of treating theumatoid arthritis ( RA) by oral administration of type Ⅱ collagen ( c Ⅱ ). Methods: N-c Ⅱ and D-c Ⅱ were respectively treated with pepsin , trypsin and α-chymotrypsin in vitro and the products were analyzecl by SDS-PAGE and Western blotting. N-c Ⅱ and D-c Ⅱ were infused to the murine stomach and duodenum. The gastric contents and intestinal contents were collected at different time and analyzed by SDS-PAGE. Results: N-c Ⅱ and its subunits could all react with the rabbit anti -c Ⅱ antibody. D-c Ⅱ was pyrolyzed to more than 10 fragments showed positive in immunoblotting . c Ⅱ could be with the lyso -state in the gastrointestinal tract. After the pepsin and α-chymotrypsin treatments , the N-c Ⅱ SDS-PAGE and immunoblotting graphs had no obvious change , but for D-c Ⅱ the positive bands in immunoblotting vanished. After the trypsin treatment ,10 positive bands in immunoblotting could be seen for N -c Ⅱ and no positive bands for D-c Ⅱ . N-C Ⅱ could not be hydrolyzed in gastric environment and could be slowly degraded in intestinal tract. D-C Ⅱ could be easily hydrolyzed by the digestive enzymes in the gastrointestinal tract. Conclusion : N-C Ⅱ can be produced active fragments by the trypsin treatment and had resistance to gastric environment , pepsin and α-hymotrypsin. D-C Ⅱ can be easily hydrolyzed by the digestive enzymes in the gastrointestinal tract. The results suggest that the inducing immunotolerance to treat RA by oral administration of C Ⅱ is possibly concerned with the C Ⅱ characteristics and trypsin enzymolysis.%目的:观察消化酶在体内和体外对天然Ⅱ型胶原蛋白(native type Ⅱ collagen,N-C Ⅱ)和变性Ⅱ型胶原蛋白(denatured type Ⅱcollagen,D-C Ⅱ)的酶解作用,探

    Full Text Available Abstract Background Exposure to persistent organic pollutants, including polychlorinated biphenyls (PCBs and organochlorine pesticides, is widespread among the general population. There is evidence of adverse effects on reproduction and early pregnancy in relation to organochlorine exposure but human studies remain limited. The increased use of assisted reproductive technologies (ART presents unique opportunities for the assessment of environmental influences on early pregnancy outcomes not otherwise observable in humans, but studies need to be designed to maximize the efficiency of the exposure data collected while minimizing exposure measurement error. Methods The present study was conducted to assess the correlation between concentrations of organochlorines in serum and follicular fluid samples collected from a subset of women undergoing ART in a large study that took place between 1994 and 2003, as well as the temporal reliability of serum organochlorine concentrations among women undergoing multiple ART cycles in the study. PCB congeners (118, 138, 153, and 180, 1,1,1-trichloro-2,2-bis(p-chlorophenylethane (p,p'-DDT, the DDT metabolite p,p'-DDE, hexachlorobenzene (HCB, oxychlordane, trans-nonachlor and mirex were measured in 72 follicular fluid samples and 265 serum samples collected from 110 women. Results Organochlorine concentrations in paired serum and follicular fluid samples were correlated, with Pearson and Spearman coefficients ranging from 0.60 to 0.92. Serum organochlorine concentrations were two- to three-fold greater than in follicular fluid, and a significant inverse trend was observed in the distribution of follicular fluid:serum ratios with increasing molecular weight of the compound (p-value for trend Conclusion Our results support the use of a single serum sample to adequately represent a more biologically relevant dose (concentrations in follicular fluid, as well as exposure levels over time, in epidemiological studies of

    Two experiments were conducted to determine if adrenal secretion of steroids differed between cows that formed ovarian follicular cysts and normal cycling cows. In experiment 1, lactating Jersey and Holstein cows were diagnosed as having ovarian follicular cysts (follicle diameter >or=20 mm) by rectal palpation. Following diagnosis, ovaries were examined by transrectal ultrasonography three times weekly to detect subsequent ovulation (n=8) or new cyst formation (n=9). Venous blood samples were collected daily to quantify circulating concentrations of cortisol and progesterone. The average concentration of cortisol during the 10-day period prior to ovulation was not different from the concentration prior to the formation of a new cyst. In experiment 2, secretion of cortisol and progesterone was examined in cows with ovarian follicular cysts (n=4) and cyclic, control cows in the follicular phase of the estrous cycle (n=4). An adrenocorticotropic hormone (ACTH) challenge was administered to cystic cows 4-7 days after new cyst formation and to cyclic cows in the follicular phase of the cycle (36 h after induction of luteolysis). Jugular venous blood samples were collected at -60, -30, 0, +10, +20, +30, +60, +90, +120, +180, +240, +300 and +360 minutes relative to ACTH administration. A rapid increase in both cortisol and progesterone was observed immediately following administration of ACTH in each treatment group. Peak concentrations of both steroids were achieved within 60 minutes after administration of ACTH. Concentrations of cortisol and progesterone did not differ between cystic and cyclic cows. In summary, no differences in adrenal function were detected between normal cycling cows and cows with ovarian follicular cysts.

    To gain insight into the evolution of differentiation pathways that are involved in the follicular cells' morphogenesis in dipteran ovaries we have undertaken the comparative morphological analysis of the follicular cell behavior in crane flies, representatives of more ancestral nematocerous flies. This analysis revealed that initially the organization of the follicular epithelium in the species under study shows significant similarities to that reported in the ovaries of true flies (Brachycera), indicating that the ancestors of dipterans must have evolved a common and specific system of the early patterning of their follicular epithelium. On the other hand, in contrast to Drosophila and other advanced brachycerans, the follicular cells in the studied nematoceran ovaries do not exhibit any migratory activity. Instead, they were found to change their relative position but only within the epithelial layer. These "translocations" appeared to depend merely on cell shape changes. Although the "immobility" of the follicular cells in the ovaries of crane flies results in the lower number of their specialized subgroups when compared with the true flies, the functional homology between particular subsets of follicular cells can be postulated. We suggest that the anterior polar cells and the micropyle forming anterior terminal follicular cells in crane fly ovaries have their counterparts in the brachyceran anterior polar cells and border cells, respectively.

    Full Text Available Follicular adenomas of the thyroid may be subjected to degenerative changes like hemorrhagic and cystic changes, fibrosis, and calcification. Mature bone formation is a rare phenomenon, but extramedullary hematopoiesis (EMH has also been rarely reported in thyroid gland. The combination of mature bone formation and EMH is rarer and has been reported, in a single case report, in a multinodular goitre. We describe a case of follicular adenoma with histologically proven osseous metaplasia and mature bone formation with EMH in a middle- aged woman, which, to our knowledge, is the first case in English language literature.

    Follicular thyroid carcinoma is the second most common type of thyroid cancer, and its incidence has increased dramatically in recent years. Although it typically presents as a thyroid nodule, it can spread to distant sites via hematogenous dissemination. Spinal cord compression complicating thyroid carcinoma is rare with only few cases reported in the literature. This case illustrates a minimally invasive follicular carcinoma that showed such an aggressive behavior, and thus the importance of considering metastatic thyroid carcinoma in the differential diagnosis of chronic back pain, which may possibly progress to spinal cord compression carrying severe morbidity.

    2013-05-01

    Odontogenic keratocyst (OKC) is one of the most aggressive odontogenic cysts known for its high recurrence rate and its tendency to invade adjacent tissues. Radiographically, OKCs can be of different varieties-follicular, envelopmental, replacemental, extraneous, and collateral. Its characteristic clinical and biological behavior, therapeutic approaches, prognosis, and recurrence vary in different studies. Generally, OKCs are found to be associated with impacted lower third molar. Here we present an unusual case of follicular OKC associated with an impacted mesiodens (supernumerary tooth) in a 21-year-old male patient.

    The study was aimed to assess the influence that short-term progesterone treatments have on follicular dynamics, oestrus and ovulation in sheep. The treatment was tested thereafter in a field trial to assess its fertility after AI with fresh semen. In a first experiment, 12 ewes without CL were grouped to receive a new (n = 6) or used CIDR (n = 6) for 7 days and blood samples were obtained to follow plasma progesterone profiles. In a second experiment, 39 cycling ewes were synchronized by a 7-day P4+PGF2α protocol using a new (n = 20) or a 7-day used CIDR (n = 19). Half of both groups received 400 IU eCG and half remained untreated as controls. Ultrasound ovarian examination and oestrous detection were used to compare follicular dynamics, oestrus and ovulation in both groups. In a third experiment, 288 ewes in 3 farms were synchronized by the short-term P4+PGF2α+eCG protocol and ewes were AI with fresh semen 24 h after oestrous detection. Lambing performance was used to test the fertility of the treatment. In Experiment 1, ewes with new inserts presented higher P4 concentration than ewes with used inserts throughout the sampling period (p 0.10). However, ewes treated with eCG show shorter interval to oestrus (p = 0.004) and tend to have larger mature CL (p = 0.06). In Experiment 3, oestrous presentation and lambing performance after AI with fresh semen was considered normal compared to published results. Results suggest that the oestrous synchronization protocol based on P4+PGF2α allows little control of follicular dynamics without compromising fertility after AI with fresh semen provided that eCG is added at the end of the treatment.
