RESUMO

Isolated sarcoidosis of the hypothalamic-pituitary system is a very rare form of neurosarcoidosis. A high index of suspicion is required for diagnosis and the choice of therapy embodies another challenge due to lack of standardized protocols. Glucocorticoids are the mainstay of initial treatment, whereas the second and third-line therapy include immunomodulators and cytotoxic drugs, in addition to monoclonal antibodies. This report presents an unusual case of panhypopituitarism in a 32-year-old previously healthy male patient due to isolated hypothalamo-pituitary sarcoidosis confirmed histologically, refractory to pulse-dose glucocorticoids and then successfully treated by methotrexate. Based on our report, in patients requiring additional therapy usage of the methotrexate as the second line agent should be considered, however the time frame and the dosing schedule of methotrexate are still unknown and deserve further investigation.

RESUMO

PURPOSE: Dabigatran use has been linked to gastrointestinal complaints, but it is unknown if this leads to more use of proton pump inhibitors (PPI). Furthermore, it is unknown whether gastrointestinal complaints occur more frequently in dabigatran users compared with other direct oral anticoagulant (DOACs) users. We investigated the association between DOAC use (dabigatran, rivaroxaban, or apixaban) and subsequent PPI initiation as a proxy for gastrointestinal complaints. METHODS: In this population-based observational study with an active-comparator new user study design, anonymised dispensing data from Community Pharmacies in the Netherlands from 2012 to 2016 were used. Patients initiating DOAC for the treatment of atrial fibrillation without any PPI use before or at time of DOAC initiation were included. The outcome measure, subsequent PPI initiation, was determined in 28553 DOAC users. RESULTS: The patients initiating dabigatran (10 942), apixaban (4897), or rivaroxaban (12714) were comparable for age (mean 69 years), sex (62% men), socioeconomic class, and concomitant medication use. The risk of PPI initiation in apixaban versus rivaroxaban users was similar (adjusted hazard ratio 1.06; 95% confidence interval 0.96-1.31) The adjusted hazard ratio of initiating PPI for dabigatran users was 1.21 (95% confidence interval 1.14-1.29) compared with rivaroxaban/apixaban users. The cumulative incidence of PPI initiation at 6 months of follow-up for patients using dabigatran was 13.0%, and 10.0% for those using rivaroxaban/apixaban, yielding a number needing treatment of 33. CONCLUSIONS: Proton pump inhibitor initiation occurred frequently in incident DOAC users but more often in patients treated with dabigatran than in those treated with rivaroxaban or apixaban.

RESUMO

Prolactinomas constitute approximately 40% of hormone-secreting pituitary tumors. In women the main clinical features are menstrual disorders and infertility. Successful treatment with dopamine agonists restores the normal function of the pituitary-gonadal axis, ovulation, and fertility. Adequate management of pregnant prolactinoma patients from the moment of conception is of particular importance for both the mother and the developing fetus. This review article presents current opinions on the course and management of pregnancies in patients with prolactin-secreting pituitary tumors. The introduction contains background information on clinical aspects of the condition, including prolactinoma treatment in women of reproductive age. Physiological changes in the pituitary during normal pregnancy are also described. The next part presents current knowledge on the effect of pregnancy on prolactinoma size, including especially the high risk of prolactinoma growth in patients with pituitary macroadenomas. Safety issues concerning the use of dopamine receptor agonists during pregnancy are also discussed, especially in terms of the risk of congenital defects in the fetus. Moreover, the article presents principles of prolactinoma management in pregnant patients, rare indications for surgical treatment during pregnancy, and the issues concerning pituitary tumor apoplexy in pregnant women, the last being a life-threatening condition. The final part of the article discusses the possible effects of pregnancy on hyperprolactinemia remission as well as on the issue of breastfeeding by mothers with prolactinoma.

RESUMO

Infectious bovine keratoconjunctivitis (IBK) is a highly contagious ocular disease of cattle caused by Moraxella bovis (Mb). Parenterally administered immunogens used to prevent the disease do not offer complete protection possibly because they stimulate a poor ocular mucosal secretory response, in which locally secreted immunoglobulin-A (sIgA) is one of the main components. The principal aim of this study was to evaluate by an indirect enzyme linked immunosorbent assay (ELISA), the local ocular mucosal sIgA response against Mb purified pili, produced after intranasal inoculation of experimental vaccines. Pili were adjuvanted by several different adjuvants (QuilA, Marcol Arlacel, Marcol Span, microencapsulated pili with PLGA polymers). Results were compared to sIgA response produced by adjuvant placebo inoculations and by IBK natural infection. Significantly higher anti-pili IgA response (p<0.05) was detected in calves vaccinated intranasally with pili QuilA and pili Marcol Span compared to control calves, although this specific immune response did not seem to be related to protection against Mb infection or typical IBK lesion development.

RESUMO

Infectious bovine keratoconjunctivitis (IBK) is an acute disease caused by Moraxella bovis (Mb). Several factors may predispose animals to an IBK outbreak; one commonly observed is infection with bovine herpes virus type 1 (BHV-1). The aim of this study was to investigate the dynamics of BHV-1 virus infection and its relation with clinical cases of IBK in weaned calves from a beef herd with a high prevalence of lesions caused by Mb. Sampling was carried out in six stages and included conjunctival swabs for isolating Mb as well as blood samples for identifying antibodies specific for BHV-1. A score for IBK lesions after observing each eye was determined. The findings of this study showed a high prevalence of BHV-1 virus infection (100% of animals were infected at the end of the trial); 67% of animals were culture-positive for Mb, but low rates of clinical IBK (19% of calves affected) were detected at the end of the trial. These results suggest that infection with BHV-1 did not predispose these animals to IBK, and that Mb infection produced clinical and subclinical disease in the absence of BHV-1 co-infection.

RESUMO

AIMS: Cervical screening, currently performed by cervical cytology, depends on the timely detection of malignant lesions for its success. The presence of high-risk human papillomavirus (hrHPV) is associated with an increased risk of subsequent high-grade cervical intra-epithelial neoplasia (CIN2/3) and cervical cancer. The aim of this study was to determine the extent to which hrHPV is present in cervical smears with a high a priori chance of being false negative (ie, in normal smears preceding CIN2/3). METHODS: Archival specimens of 187 women with CIN2/3 and preceding normal conventional smears were identified retrospectively. Of these specimens, 144 (77%) had adequate cytological samples for further HPV DNA testing. RESULTS: Of 144 CIN2/3 lesions, preceding normal smears showed hrHPV positivity in 80% of cases. Of the hrHPV-positive smears, 69% were upgraded cytologically at rescreening compared with 24% of hrHPV-negative smears (p<0.001). Upgrading of smears was not associated with specific hrHPV types (p = 0.217). In over 90% of cases, type concordance in smear and CIN2/3 lesion was demonstrated. CONCLUSIONS: hrHPV is present in a high proportion of normal archival smears preceding CIN2/3, and false-negative cytology was highly associated with the presence of hrHPV. This supports the current notion that hrHPV testing can be used as a primary cervical screening tool. If so, hrHPV-positive cervical smears should be carefully examined for cytological abnormalities to reduce false-negative cervical cytology.

RESUMO

We present the type-distribution of high-risk human papillomavirus (HPV) types in women with normal cytology (n=1467), adenocarcinoma in situ (ACIS) (n=61), adenocarcinoma (n=70), and squamous cell carcinoma (SCC) (n=83). Cervical adenocarcinoma and ACIS were significantly more frequently associated with HPV18 (OR(MH) 15.0; 95% CI 8.6-26.1 and 21.8; 95% CI 11.9-39.8, respectively) than normal cytology. Human papillomavirus16 was only associated with adenocarcinoma and ACIS after exclusion of HPV18-positive cases (OR(MH) 6.6; 95% CI 2.8-16.0 and 9.4; 95% CI 2.8-31.2, respectively). For SCC, HPV16 prevalence was elevated (OR(MH) 7.0; 95% CI 3.9-12.4) compared to cases with normal cytology, and HPV18 prevalence was only increased after exclusion of HPV16-positive cases (OR(MH) 4.3; 95% CI 1.6-11.6). These results suggest that HPV18 is mainly a risk factor for the development of adenocarcinoma whereas HPV16 is associated with both SCC and adenocarcinoma.

RESUMO

Cancer of the uterine cervix is the second most common cancer in women worldwide. Currently, cervical screening is based on cytology alone. Because infection with high-risk human papillomavirus types (hrHPVs) is a necessary cause of cervical cancer, it has been postulated that screening might become more efficient when it is based on combined cytology and hrHPV testing. In this review we will discuss the advantages of added HPV tests in cervical cancer screening, as a quality control for false-negative smears, in triage of women with equivocal smears, in follow-up of women treated for CIN3 or cervical cancer and for the detection of cervical adenocarcinoma.

RESUMO

According to the current guidelines in most western countries, women treated for cervical intraepithelial neoplasia grade 3 (CIN 3) are followed for at least 2 years after treatment by cytology.High-risk human papillomavirus (hrHPV) infections are necessary for the development and maintenance of CIN 3. HrHPV testing could be used to improve monitoring of women treated for CIN 3. This has prompted numerous studies for the implementation of hrHPV testing in monitoring of women treated for CIN 3. Included in this review are 20 studies, published between 1996 and 2003, comparing hrHPV testing with either resection margins or cervical cytology to predict recurrent/residual disease, and 11 of them could be used in a meta-analysis. In the meta-analysis of the 11 studies, the negative predictive value (NPV) for recurrent/residual disease of hrHPV testing was 98% (95% CI 97-99%), that of resection margins 91% (95% CI 87-94%), and that of cervical cytology 93% (95% CI 90-95%). When hrHPV testing was performed in conjunction with cytology, the sensitivity was 96% (95% CI 89-99%), specificity was 81% (95% CI 77-84%), the associated positive predictive value (PPV) was 46% (95% CI 38-54%), and the NPV was 99% (95% CI 98-100%). Combined hrHPV and cytology testing yielded the best test characteristics. We propose to include hrHPV testing in conjunction with cytology for monitoring women treated for CIN 3. Some follow-up visits for women testing negative for both hrHPV and cytology can be skipped. In western countries, this could mean that for women double negative at 6 months, retesting at 12 months should be skipped while keeping the 24-month follow-up visit.

RESUMO

Most cases of periaqueductal tumours were found in children and adolescents, so treatment modalities in adults are not evaluated yet. A case of 40 years old woman with tectal and periaqueductal protoplasmatic astrocytoma grade II with history of headache and episodes of syncope is described. MRI showed triventricular hydrocephalus. After a shunt procedure she was doing well for about 15 months. Then she became somnolent, disoriented, and Parinaud syndrome appeared. The solid tumour was resected microsurgically in one stage. A part of it was removed via the supracerebellar infratentorial approach and tectal plate incision. The remainder of the tumour was removed through the fourth ventricle and the aqueduct which was filled by tumour mass. Postoperatively bilateral ptosis, vertical gaze palsy, slight horizontal gaze limitation and pupilloplegia were the main neurological sequelae. They all almost completely resolved within a year. The patient is doing well two and half years after the surgery. MRI showed patency of the aqueduct and no residual tumour. The authors suggest, that direct surgical attempt at total tumour removal should be considered in cases of periaqueductal and tectal gliomas. They also believe it is the first described case, in whom this type of tumour was totally removed by a combined transtectal and transaqueductal route.

RESUMO

Adenocarcinoma in situ (ACIS) and adenocarcinoma (AdCA) of the cervix are frequently missed in population-based screening programmes. Adding high-risk HPV (hrHPV) testing to cervical cancer screening might improve the detection rate of ACIS and AdCA. Since the exact proportion of AdCAs of the cervix that can be attributed to hrHPV infection is still a matter of debate, a comprehensive study was performed of hrHPV presence in ACIS and AdCA of the cervix. Archival formalin-fixed specimens of indisputable ACIS (n=65) and AdCA (n=77) of the cervix were tested for hrHPV DNA by GP5+/6+ PCR-enzyme immunoassay (EIA) and type-specific E7 PCR for 14 hrHPV types. Further immunostaining for p16INK4A and p53 was performed to assess alternative pathways of carcinogenesis potentially unrelated to HPV. hrHPV DNA was found in all (100%) ACISs and 72 (94%) cervical AdCAs, whereas none of 20 endometrial AdCAs scored hrHPV-positive. HPV 18 was most prevalent and found as single or multiple infection in 68% of ACISs and 55% of cervical AdCAs. Diffuse immunostaining for p16INK4a, a potential marker of hrHPV E7 function, was significantly more frequent in hrHPV-positive cervical AdCAs (19/20; 95%) than in those without hrHPV (1/5; 20%; p<0.001). Immunostaining for p53, pointing to stabilized wild-type or mutant p53 protein, was significantly more frequent in hrHPV cervical AdCAs negative for hrHPV (p=0.01). No difference in p16INK4a and p53 immunostaining was found between hrHPV-negative cervical AdCAs and endometrial AdCAs. Hence, only a minority of cervical AdCAs displayed absence of HPV DNA and immunostaining profiles suggestive of an aetiology independent of HPV. Since all ACISs and nearly all cervical AdCAs were hrHPV-positive, the incorporation of hrHPV testing in cervical cancer screening programmes is likely to decrease markedly the incidence of cervical AdCA.

RESUMO

OBJECTIVE: We evaluated high-risk human papillomavirus (HPV) testing by Hybrid Capture II (HC II) in addition to cytology to predict recurrent/residual cervical intraepithelial neoplasia (CIN) 2/3 and cervical cancer in women treated for CIN 3. METHODS: Follow-up study of 108 women with histologically confirmed CIN 3. RESULTS: Pretreatment, in 96% (104/108) of the smears high-risk HPV DNA was present. Posttreatment, 71% (77/108) of the women had normal cytology and negative HC II test and none developed recurrent/residual disease during a median follow-up of 28.8 months with a range of 2.4-64.8 months. One of the 12% (13/108) of women with normal cytology and positive HC II test was diagnosed with cervical adenocarcinoma. One of the 7% (8/108) of women with abnormal cytology (borderline dyskaryosis or worse) and negative HC II test was diagnosed with CIN 2. Three of the 9% (10/108) of women with abnormal cytology and a positive HC II test were diagnosed with CIN 2/3. These results show an increased risk for recurrent/residual CIN 2/3 and cervical carcinoma when at least one posttreatment test is positive. The highest relative risk (72.9, 95% CI 25-210) was present in women with both tests positive. CONCLUSIONS: HPV testing with Hybrid Capture II in conjunction with cytology can be used as a tool to select women with an increased risk for recurrent/residual CIN 2/3 and cervical cancer. The standard policy in The Netherlands is cytology at 6, 12, and 24 months posttreatment. However, for women with both normal cytology and negative HC II test at 6 months the chance to develop recurrent/residual CIN 2/3 and cervical carcinoma is so low that retesting at 12 months can be omitted.

RESUMO

To evaluate the therapeutic efficacy of slow releasing analogue of somatostatin (SR-Lanreotide) in the pretreatment for GH-releasing adenomas, especially macroadenomas. During the last four years (between January 1996 and December 1999) the authors carried out 382 transsphenoidal operations for to various lesions. There were 169 acromegalic patients in this group. 82 of them received, as pretreatment, the slow releasing analogue of somatostatin (SR-Lanreotide, BIM 23014) in a dose of 30 mg every 14 days for 3 months (6 injections). There were 55 women and 27 men (range 25-68, mean age 44.8 years, SD +/- 10 years) operated on by one experienced neurosurgeon. The concentrations of serum GH--70.5 micrograms/l (range 5.3-500 micrograms/l, SD +/- 83.9 micrograms/l) and IGF-I--1302 micrograms/l (range 610-2030 micrograms/l, SD +/- 360.7 micrograms/l) were high. Out of these 82 patients 79 had macroadenomas with suprasellar and parasellar extension. The volume of the tumours was calculated according to the formula of Di Chiro-Nelson. The mean volume of the tumour was 4146.9 mm3 (range 213.5-38595.3 mm3, SD +/- 5675.9 mm3). The response to the pretreatment suppression of the serum GH, IGF-I level and shrinkage of the tumours--were evaluated before surgery. Second MR examination was performed in 38 pretreated patients. During the Lanreotide treatment mean serum GH level decreased from 70.5 to 15.6 micrograms/l (p < 0.0001), mean serum IGF-I concentration decreased from 1302 to 787 micrograms/l and mean volume of the tumour decreased from 5662 to 2326 mm3 (p < 0.0001). During surgery, tumours were observed to be softer, had liquid consistency and were easier removed. 57 patient (69.5%) who underwent surgery had GH below 5 micrograms/l and were cured. Transsphenoidal microsurgical resection of pituitary adenomas is the primary treatment for acromegaly. Lanreotide pretreatment significantly decreased mean serum GH and IGF-I level, shrinks the tumour and make it much softer and easier to be removed.

RESUMO

In The Netherlands and most other European countries, women with two serial cervical smears with borderline or mild dyskaryosis (BMD) within 6 months are referred for colposcopy-directed biopsies. Only about 10% of these women have high-grade cervical intraepithelial neoplasia (CIN). This study therefore investigated whether human papillomavirus (HPV) testing could identify which women with smears read as BMD are most likely to have high-grade CIN, either at referral or during follow-up and the relationship was determined between clearance of high-risk HPV and regression of abnormal cytology. Women with smears read as BMD (n=278) were referred to the gynaecologist for colposcopy. They were subdivided into two groups; group A comprised women with a single smear (n=172) and group B women with two sequential smears (n=106) read as BMD before referral. High-risk HPV detection with Hybrid Capture II (HC II) was performed on a cervical scrape taken at the first visit before colposcopy (i.e. baseline smear) and during follow-up. Biopsies were taken when lesions suspected for CIN were seen at colposcopy. High-risk HPV DNA was present in the baseline smears of 126 (45.0%) women; 26 (20.6%) of them had histologically confirmed CIN 2/3 at the first visit and another 14 (11.1%) during follow-up. Only one of the 152 women (0.7%) with a negative high-risk HPV test had a CIN 2 lesion at the first visit and no CIN lesions were detected during follow-up of these women. After exclusion of women who were treated for prevalent high-grade CIN, the median follow-up times were 1.3 years (range 0.0-4.3 years) and 1.6 years (range 0.0-4.5 years) for women with HPV-negative and HPV-positive baseline smears, respectively. The sensitivity of a positive high-risk HPV test for CIN 2/3 at the first visit was 96.3%, the specificity 60.2%, the positive predictive value 20.6%, and the negative predictive value 99.3%. These values did not change markedly when stratified for group A or group B. Thus, a high-risk HPV positive test was strongly associated with the presence at the first visit and the development of CIN 2/3 lesions during follow-up. Moreover, regression of abnormal cytology in women with a positive high-risk HPV test at baseline was strongly associated with viral clearance and occurred 0.3 years (range -1.2 to 1.7 years) later than HPV clearance. This study establishes the value of a high-risk HPV positive test for women at risk of high-grade CIN, with virtually no risk for missing CIN 2/3. Addition of a test on high-risk HPV in women with BMD could prevent 55% of the referrals and/or repeat smears.

RESUMO

In a retrospective case-control study, we investigated high-risk HPV DNA presence by general primer GP5+/6+ PCR in the last normal cervical smear in the patient archives (i.e. baseline smear) of 57 women who later developed cervical cancer. Also, normal cervical smears of 114 age-matched control women were analysed. High-risk HPV DNA was detected in 37 of the 57 (65%) baseline smears of the case women, and 7 (6%) of 114 smears of the control women (OR 28, 95% Cl 11-72). The HPV positive subsequent smears and cervical cancer biopsies of the case women contained the same HPV type as was detected in the baseline smear. After cytological revision, the baseline smears of 48 case women (84%) were reclassified as abnormal, 33 (69%) of which scored high-risk HPV DNA positive. Ultimately, an undisputable normal baseline smear was found in only 10 case women. In 7 (70%) of them this smear was HPV positive, whereas only 7 (7%) of 104 revised, undisputable normal smears of control women were high-risk HPV positive (OR 32, 95% Cl 6.8-153). The results showed that (1) high-risk HPV presence precedes abnormal cytology in women who develop cervical cancer, and (2) high-risk HPV testing signals false-negative smears of women at risk of cervical cancer.

RESUMO

A case of 39 years old woman with two intracranial meningiomas and syringomyelia is presented. Large right-sided tentorial meningioma in cerebellopontine angle and middle cranial fossa and small left sided sphenoid wing meningioma co-existed with secondary tonsillar herniation and large syringomyelic cavity in cervical and thoracic spinal cord. The patient had dissociated sensory loss on trunk and upper left extremity, muscle atrophy, left hand paresis, long tracts signs. After having done atlanto-occipital decompression, the intramedullary cavity collapsed and neurological symptoms resolved. Two months later large tentorial meningioma was successfully removed via occipito-suboccipital craniotomy with tentorial transsection. A review of the literature concerning syringomyelia secondary to intracranial tumours was done. To our knowledge this is the first such case described in which syringomyelia syndrome was the prominent symptom of the disease and two staged surgical procedure, first oriented at treatment of syringomyelia itself, was applied.

RESUMO

The antimicrobial susceptibility of 88 isolates of Moraxella bovis of Argentine origin was evaluated for 12 antimicrobials by broth microdilution procedures. The isolates had a minimum inhibitory concentration (MIC90) of < or = 0.06 microg/mL to enrofloxacin; < or = 0.12 microg/mL to ceftiofur; < or = 0.25 microg/mL to ampicillin; < or = 0.5 microg/mL to florfenicol and gentamicin; < or = 1.0 microg/mL to tilmicosin, erythromycin, and oxytetracycline; < or = 4.0 microg/mL to tylosin; < or = 8.0 microg/mL to spectinomycin; < or = 0.25/4.75 microg/mL to trimethoprim/sulfamethoxazole; and > or = 32 microg/mL to lincomycin. Modal MIC values for these antimicrobials were as follows: enrofloxacin, 0.03 microg/mL; ceftiofur, 0.06 pg/mL; ampicillin, 0.25 microg/mL; florfenicol, gentamicin, erythromycin, and oxytetracycline, 0.5 microg/mL; tilmicosin, 1.0 microg/mL; tylosin and spectinomycin, 4.0 microg/mL; lincomycin and erythromycin, 16 microg/mL; and trimethoprim/ sulfamethoxazole, < or = 0.25/4.75 microg/mL. These data show that all antimicrobials except lincomycin have MICs suggestive of sensitivity in vitro, though confirmation of clinical efficacy can only be properly assessed based on pharmacologic and/or clinical data to support the MIC values.

RESUMO

In general, condylomata acuminata can be diagnosed and treated by the general practitioner. Condylomata are caused by certain types of human papillomavirus (HPV). According to their carcinogenicity HPVs are classified as high risk and low risk HPV. The benign condylomata are an infrequent sign of an infection with low risk HPV, while cervical cancer is a rare and late complication of an infection with high risk HPV. Because high and low risk HPV are different viruses, the risk of cervical cancer is not increased by condylomata. Anogenital HPVs are predominantly transmitted sexually. It is useful to discriminate between sexually transmitted diseases (STDs) that are ubiquitous, like infections with HPV or herpes simplex virus (HSV), and rare STDs like syphilis, gonorrhoea and HIV infection: infections with HPV and HSV are also common with unriskful sexual behaviour, while syphilis, gonorrhoea and HIV infection are almost exclusively associated with riskful sexual behaviour. It has been shown that double infections with HPV and Chlamydia trachomatis are not more frequent than may be expected by chance. The literature indicates that the presence of condylomata acuminata by itself is no reason to screen patients for other STDs.
