BACKGROUND
Dyskeratosis congenita (DC) is a rare genetic disorder of poor telomere maintenance. Pulmonary fibrosis (PF) related to DC is rarely reported.
CASE PRESENTATION
A 23-year-old student presented with a four-year history of progressive cough and exertional dyspnea. Physical examination was remarkable for typical mucocutaneous abnormalities. Chest computerized tomography scan revealed interstitial fibrosis. Testing of peripheral blood leukocytes confirmed that his telomeres were 30th percentile of age-matched controls. A heterozygous missense mutation located in exon 22 of PARN gene was identified in the patient by whole exome sequencing. The patient refused danazol therapy and lung transplantation, and died of respiratory failure 2 years later. In addition, this case and 26 reported cases of DC-related PF identified through the comprehensive search of PubMed, Web of Science, WANFANG and CNKI were reviewed. Later-onset PF was observed in 11 patients (40.7%). Radiological usual interstitial pneumonia (UIP) pattern or possible UIP pattern was noted only in half of patients. However, histopathological UIP or probable UIP patterns were found in 63.6% of patients. Age at bone marrow failure (BMF) and the frequency of normal to mild thrombocytopenia in later-onset patients was significantly higher than in early-onset patients (p = 0.017 and p = 0.021, respectively). Age at PF and age at BMF in DC patients with TERC/TERT variants was significantly higher than in those with TINF2 variants or DKC1/NHP2 variants (p = 0.004 and p = 0.003, respectively). The patients with TERT/TERC/RTEL1/PARN variants had a significantly better transplant-free survival than those with TINF2 variants or DKC1/NHP2 variants (p < 0.05). Patients who underwent surgical lung biopsy had significantly worse transplant-free survival than those without lung biopsy (p = 0.042). Worse survival was found in patients with immunosuppression therapy than in those without (p = 0.012).
CONCLUSIONS
It is common for DC-associated PF to occur later in life without significant hematological manifestations. Mutations in the genes encoding different components of the telomere maintenance pathway were associated with clinical phenotypes and prognosis. PF caused by DC should be kept in mind by clinicians in the differential diagnosis of patients with unexplained PF and should be excluded before diagnostic surgical lung biopsy is undertaken or empirical immunosuppression therapy is prescribed.

Meta-Analysis Review
Mastalgia, or breast pain, is common among women which can lead to significant impairment in daily living. Hence, finding an effective treatment that can alleviate the symptom is very important. Thus, we carry out this study to determine the efficacy of evening primrose oil (EPO) for mastalgia treatment in women. The review included published randomised clinical trials that evaluated EPO used for treating mastalgia against a placebo or other treatments, irrespective of the blinding procedure, publication status, or sample size. Two independent authors screened the titles and abstracts of the identified trials; full texts of relevant trials were evaluated for eligibility. Two reviewers independently extracted data on the methods, interventions, outcomes, and risk of bias. The random-effects model was used for estimating the risk ratios and mean differences with 95% confidence intervals. Thirteen trials with 1752 randomised patients were included. The results showed that EPO has no difference to reduce breast pain compared to topical NSAIDS, danazol, or vitamin E. The number of patients who achieved pain relief was no different compared to the placebo or other treatments. The EPO does not increase adverse events, such as nausea, abdominal bloating, headache or giddiness, increase weight gain, and altered taste compared to a placebo or other treatments. EPO is a safe medication with similar efficacy for pain control in women with mastalgia compared to a placebo, topical NSAIDS, danazol, or vitamin E.

Comparative Study Meta-Analysis
OBJECTIVE
To quantify the efficacy of medical management of uterine arteriovenous malformation (AVM) and compare efficacy between different classes of medication. In addition, we evaluated for factors associated with treatment success and pregnancy outcomes after medical management.
DESIGN
Systematic review and meta-analysis.
SETTING
Not applicable.
PATIENT(S)
Thirty-two studies representing 121 premenopausal women with medically-treated uterine AVM were identified via database searches of MEDLINE, Embase, Web of Science, and cited references.
INTERVENTION(S)
Medical treatment with progestins, gonadotropin-releasing hormone agonists (GnRH-a), methotrexate, combined hormonal contraception , uterotonics, danazol, or combination of the above.
MAIN OUTCOME MEASURE(S)
Primary outcome of treatment success was defined as AVM resolution without subsequent procedural interventions. Secondary outcome was treatment complication (readmission or transfusion).
RESULT(S)
The overall success rate of medical management was 88% (106/121). After adjusting for clustering effects, success rates for progestin (82.5%; 95% confidence interval [CI], 70.1%-90.4%), GnRH-a (89.3%; 99% CI, 71.4%-96.5%) and methotrexate (90.0%; 99% CI, 55.8%-98.8%) were significantly different from the null hypothesis of 50% success. The agents with the lowest adjusted proportion of complications were progestins (10.0%; 99% CI, 3.3%-26.8%) and GnRH-a (10.7%; 99% CI, 3.5%-28.4%). No clinical factors were found to predict treatment success. Twenty-six subsequent pregnancies are described, with no reported recurrences of AVM.
CONCLUSION(S)
Medical management for uterine AVM is a reasonable approach in a well selected patient. These data should be interpreted in the context of significant publication bias.

Meta-Analysis Review
Recurrent gastrointestinal bleeding (GIB) is a common complication following left ventricular assist device (LVAD) implantation. Our study aimed to estimate the comparative efficacy of different pharmacologic interventions for the prevention of GIB, through a network meta-analysis (NMA). A total of 13 observational studies comparing six strategies. Among those, 4 were for primary, and 9 were for secondary prevention of GIB. On NMA, thalidomide (Hazard ratio [HR]: 0.016, Credible interval [CrI]I: 0.00053-0.12), omega-3-fatty acid (HR:0.088, CrI: 0.026-0.77), octreotide (HR: 0.17, CrI: 0.0589-0.41) and danazol (HR:0.17, CrI: 0.059-0.41) reduced the risk of GIB. The use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blocker (ACEi/ARB) and digoxin were not associated with any significant reduction. Based on NMA, combining indirect treatment comparisons, thalidomide, danazol, and octreotide treatments were associated with decreased risk of recurrent GIB. Additionally, Omega 3 fatty acids were associated with a lower risk of the primary episode of GIB in the LVAD patient population.

BACKGROUND
Idiopathic intracranial hypertension (IIH) is a condition with increased intracranial pressure of unknown etiology. Its presenting symptoms include persistent headache, pulsatile tinnitus, and visual obscuration. It tends to occur in obese women of childbearing age, and its greatest risk is irreversible loss of vision. Some of the commonly used medications in dermatology, especially those for acne vulgaris, have been associated with IIH. However, the creation of specific risk categories for drugs as a guide for clinicians has never been performed.
OBJECTIVE
The aim of this study was to critically assess all published cases of IIH and identify high-risk drugs associated with drug-induced intracranial hypertension (DIIH), to assist dermatologists and other physicians with patient education and monitoring of symptoms of secondary intracranial hypertension.
METHODS
MEDLINE, EMBASE, and Cochrane Review Databases were searched for all cases of IIH thought to be drug-related between January 1900 and June 2019. A total of 5117 articles were identified, and 235 articles were found to be relevant. All cases were assessed to satisfy the modified Dandy criteria for diagnosis of IIH, and the likelihood of each case being a 'definite' adverse drug reaction (ADR) was determined using the Koh algorithm for ADR. An association category (from weakly associated [Category I] to strongly associated [Category V]) was assigned based on the number of cases meeting these two criteria.
RESULTS
There were 259 verifiable cases of DIIH. Vitamin A derivatives, tetracycline-class antibiotics, recombinant growth hormone, and lithium were found to be most strongly associated with DIIH (Categories IV and V). Corticosteroids were moderately associated with DIIH (Category III). Drugs that were weakly associated with DIIH (Categories I and II) include cyclosporine, progestin-only contraceptives, combined oral contraceptives, second- and third-generation fluoroquinolones, sulfenazone, gonadotropin-releasing hormones and luteinizing hormone-releasing hormone agonist, nalidixic acid, amiodarone, stanozolol, danazol, divalproic acid, sulfasalazine, ketoconazole, and ustekinumab.
CONCLUSION
We suggest using the term 'drug-induced intracranial hypertension' (DIIH) and propose a set of diagnostic criteria for DIIH. Our review attempts to identify DIIH-associated drugs based on a strict diagnostic and drug-causality algorithm, then stratify them into appropriate risks categories. This may ultimately assist physicians in counselling patients about the risk of DIIH when prescribing medications and recognizing this uncommon yet sight-threatening condition.

BACKGROUND
Heavy menstrual bleeding (HMB) is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce prostaglandin levels, which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea.
OBJECTIVES
To determine the effectiveness, safety and tolerability of NSAIDs in achieving a reduction in menstrual blood loss (MBL) in women of reproductive years with HMB.
SEARCH METHODS
We searched, in April 2019, the Cochrane Gynaecology and Fertility specialised register, Cochrane Central Register of Studies Online (CENTRAL CRSO), MEDLINE, Embase, PsycINFO, the clinical trial registries and reference lists of articles.
SELECTION CRITERIA
The inclusion criteria were randomised comparisons of individual NSAIDs or combined with other medical therapy with each other, placebo or other medical treatments in women with regular heavy periods measured either objectively or subjectively and with no pathological or iatrogenic (treatment-induced) causes for their HMB.
DATA COLLECTION AND ANALYSIS
We identified 19 randomised controlled trials (RCTs) (759 women) that fulfilled the inclusion criteria for this review and two review authors independently extracted data. We estimated odds ratios (ORs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes from the data of nine trials. We described in data tables the results of the remaining seven cross-over trials with data unsuitable for pooling, one trial with skewed data, and one trial with missing variances. One trial had no data available for analysis.
MAIN RESULTS
As a group, NSAIDs were more effective than placebo at reducing HMB but less effective than tranexamic acid, danazol or the levonorgestrel-releasing intrauterine system (LNG IUS). Treatment with danazol caused a shorter duration of menstruation and more adverse events than NSAIDs, but this did not appear to affect the acceptability of treatment, based on trials from 1980 to 1990. However, currently danazol is not a usual or recommended treatment for HMB. There was no clear evidence of difference between NSAIDs and the other treatments (oral luteal progestogen, ethamsylate, an older progesterone-releasing intrauterine system and the oral contraceptive pill (OCP), but most studies were underpowered. There was no evidence of a difference between the individual NSAIDs (naproxen and mefenamic acid) in reducing HMB. The evidence quality ranged from low to moderate, the main limitations being risk of bias and imprecision.
AUTHORS' CONCLUSIONS
NSAIDs reduce HMB when compared with placebo, but are less effective than tranexamic acid, danazol or LNG IUS. However, adverse events are more severe with danazol therapy. In the limited number of small studies suitable for evaluation, there was no clear evidence of a difference in efficacy between NSAIDs and other medical treatments such as oral luteal progestogen, ethamsylate, OCP or the older progesterone-releasing intrauterine system.

BACKGROUND
Heavy menstrual bleeding (HMB) is a menstrual blood loss perceived by women as excessive that affects the health of women of reproductive age, interfering with their physical, emotional, social and material quality of life. Whilst abnormal menstrual bleeding may be associated with underlying pathology, in the present context, HMB is defined as excessive menstrual bleeding in the absence of other systemic or gynaecological disease. The first-line therapy is usually medical, avoiding possibly unnecessary surgery. Of the wide variety of medications used to reduce HMB, oral progestogens were originally the most commonly prescribed agents. This review assesses the effectiveness of two different types and regimens of oral progestogens in reducing ovulatory HMB.This is the update of a Cochrane review last updated in 2007, and originally named "Effectiveness of cyclical progestagen therapy in reducing heavy menstrual bleeding" (1998).
OBJECTIVES
To determine the effectiveness, safety and tolerability of oral progestogen therapy taken either during the luteal phase (short cycle) or for a longer course of 21 days per cycle (long cycle), in achieving a reduction in menstrual blood loss in women of reproductive age with HMB.
SEARCH METHODS
In January 2019 we searched Cochrane Gynaecology and Fertility's specialized register, CENTRAL, MEDLINE, Embase, CINAHL and PsycInfo. We also searched trials registers, other sources of unpublished or grey literature and reference lists of retrieved trials. We also checked citation lists of review articles to identify trials.
SELECTION CRITERIA
Randomized controlled trials (RCTs) comparing different treatments for HMB that included cyclical oral progestogens were eligible.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected trials for inclusion, assessed trials for risk of bias and extracted data. We contacted trial authors for clarification of methods or additional data when necessary. We only assessed adverse events if they were separately measured in the included trials. We compared cyclical oral progestogen in different regimens and placebo or other treatments. Our primary outcomes were menstrual blood loss and satisfaction with treatment; the secondary outcomes were number of days of bleeding, quality of life, compliance and acceptability of treatment, adverse events and costs.
MAIN RESULTS
This review identified 15 randomized controlled trials (RCTs) with 1071 women in total. Most of the women knew which treatment they were receiving, which may have influenced their judgements about menstrual blood loss and satisfaction. Other aspects of trial quality varied among trials.We did not identify any RCTs comparing progestogen treatment with placebo. We assessed comparisons between oral progestogens and other medical therapies separately according to different regimens.Short-cycle progestogen therapy during the luteal phase (medroxyprogesterone acetate or norethisterone for 7 to 10 days, from day 15 to 19) was inferior to other medical therapy, including tranexamic acid, danazol and the progestogen-releasing intrauterine system (Pg-IUS (off of the market since 2001)), releasing 60 mcg of progesterone daily, with respect to reduction of menstrual blood loss (mean difference (MD) 37.29, 95% confidence interval (CI) 17.67 to 56.91; I = 50%; 6 trials, 145 women). The rate of satisfaction and the quality of life with treatment was similar in both groups. The number of bleeding days was greater on the short cycle progestogen group compared to other medical treatments. Adverse events (such as gastrointestinal symptoms and weight gain) were more likely with danazol when compared with progestogen treatment. We note that danazol is no longer in general use for treating HMB.Long-cycle progestogen therapy (medroxyprogesterone acetate or norethisterone), from day 5 to day 26 of the menstrual cycle, is also inferior to the levonorgestrel-releasing intrauterine system (LNG-IUS), releasing tranexamic acid and ormeloxifene, but may be similar to the combined vaginal ring with respect to reduction of menstrual blood loss (MD 16.88, 95% CI 10.93 to 22.84; I = 87%; 4 trials, 355 women). A higher proportion of women taking norethisterone found their treatment unacceptable compared to women having Pg-IUS (Peto odds ratio (OR) 0.12, 95% CI 0.03 to 0.40; 1 trial, 40 women). However, the adverse effects of breast tenderness and intermenstrual bleeding were more likely in women with the LNG-IUS. No trials reported on days of bleeding or quality of life for this comparison.The evidence supporting these findings was limited by low or very low gradings of quality; thus, we are uncertain about the findings and there is a potential that they may change if we identify other trials.
AUTHORS' CONCLUSIONS
Low- or very low-quality evidence suggests that short-course progestogen was inferior to other medical therapy, including tranexamic acid, danazol and the Pg-IUS with respect to reduction of menstrual blood loss. Long cycle progestogen therapy (medroxyprogesterone acetate or norethisterone) was also inferior to the LNG-IUS, tranexamic acid and ormeloxifene, but may be similar to the combined vaginal ring with respect to reduction of menstrual blood loss.

INTRODUCTION
Ten to 15% of common variable immunodeficiencies (CVID) develop auto-immune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). Treatment is based on immunosuppressants, which produce blocking effects in the CVID. Our objective was to assess their risk-benefit ratio in these immunocompromised patients.
METHODS
We identified 17 articles detailing the treatment of AIHA and/or ITP in patients suffering from CVID through a systematic review of the MEDLINE database.
RESULTS
The increased infectious risk with corticosteroids does not call into question their place in the first line of treatment of ITP and AIHA in CVID. High-doses immunoglobulin therapy remain reserved for ITP with a high risk of bleeding. In second-line treatment, rituximab appears to be effective, with a lower infectious risk than the splenectomy. Immunosuppressants (azathioprine, methotrexate, mycophenolate, cyclophosphamide, vincristine, ciclosporine) are moderately effective and often lead to severe infections, meaning that their use is justified only in resistant cases and steroid-sparing. Dapsone, danazol and anti-D immunoglobulins have an unfavorable risk-benefit ratio. The place of TPO receptor agonists is still to be defined. The establishment of immunoglobulin replacement in the place of immunosuppressants (except for short-term corticotherapy) or splenectomy appears to be essential to limit the risk of infections, including in the absence of previous infections.
CONCLUSION
The presence of CVID does not mean that it is necessary to give up on corticosteroids as a first-line treatment and rituximab as a second-line treatment for AIHA and ITP, but it should be in addition to immunoglobulin replacement. A splenectomy should be reserved as a third-line treatment.

INTRODUCTION Idiopathic mastalgia (benign breast pain of unknown origin) is often poorly managed because of its subjective nature and unclear aetiology. Mastalgia is a reason for up to 50% of breast outpatient referrals. Existing systematic reviews discuss dated treatment options that provide limited symptomatic relief. METHODS A systematic review was conducted for aetiology and treatment of idiopathic mastalgia in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidance. Databases such as PubMed, MEDLINE, Cochrane Database and the Clinical Trial Registry were searched (February 2016). RESULTS Reassurance plus bra-fitting advice provides relief for most women. If symptoms persist, addition of topical non-steroidal anti-inflammatory drugs (NSAIDs) provides relief in 70-92% of women. There is some benefit in reducing dietary coffee and fat intake. Medical treatments have serious side-effects (often androgenic or menopausal) and should be considered only in cases resistant to simpler measures. Dopamine agonists are useful, but less effective than endocrine treatments such as Danazol or Tamoxifen. Of the Selective Oestrogen Receptor Modulator drugs, Ormeloxifene appears most effective, but is not licenced in the United Kingdom. Relaxation therapy, acupuncture and kinesiology may be useful but currently lack good evidence of effectiveness. DISCUSSION First-line management of breast pain should be explanation, reassurance and a bra-fitting advice. Subsequent drug therapy should be balanced against its side-effects; topical NSAIDs and Ormeloxifene show greatest benefit with least side-effects. Newer agents (Ormeloxifene) currently being used for mastalgia in India could be considered in the developed world.
