A lightweight deep learning architecture for the automatic detection of pneumonia using chest X-ray images.

Pneumonia is a life-threatening respiratory lung disease. Children are more prone to be affected by the disease and accurate manual detection is not easy. Generally, chest radiographs are used for the manual detection of pneumonia and expert radiologists are required for the assessment of the X-ray images. An automatic system would be beneficial for the diagnosis of pneumonia based on chest radiographs as manual detection is time-consuming and tedious. Therefore, a method is proposed in this paper for the fast and automatic detection of pneumonia. A deep learning-based architecture 'MobileNet' is proposed for the automatic detection of pneumonia based on the chest X-ray images. A benchmark dataset of 5856 chest X-ray images was taken for the training, testing, and evaluation of the proposed deep learning network. The proposed model was trained within 3 Hrs. and achieved a training accuracy of 97.34%, a validation accuracy of 87.5%, and a testing accuracy of 94.23% for automatic detection of pneumonia. However, the combined accuracy was achieved as 97.09% with 0.96 specificity, 0.97 precision, 0.98 recall, and 0.97 F-Score. The proposed method was found faster and computationally lesser expensive as compared to other methods in the literature and achieved a promising accuracy.

Bevacizumab as an Adjunct to Trabeculectomy in Primary Open-Angle Glaucoma: A Randomized Trial.

PURPOSE: To compare the outcomes of trabeculectomy using two different routes of bevacizumab administration as an adjunct in patients with primary open angle glaucoma. METHODS: Prospective, randomized, masked trial that included 180 eyes of 180 patients of documented primary open angle glaucoma were eligible for surgery. Patients were randomized to receive either a single intraoperative dose of subconjunctival bevacizumab (1.25 mg, Group I) or topical bevacizumab (5 mg/ml) for 30 days (Group II). One eye was randomly selected, if both were eligible for surgery. All patients underwent a complete ocular and systemic examination. Bleb morphology was examined and scored as per Moorfields system (MBGS) at 1, 3, 6, 12, 18, and 24 months postoperatively. Visual field, fundus photography, and disc analysis were performed. Outcome measures (at one year) included (1) comparison of bleb morphology in both groups, (2) proportion of patients achieving surgical success, and (3) side effects of treatment. RESULTS: The groups did not differ with respect to age, sex, and crystalline lens status. Group II patients had significantly lower vascularity scores for central (P=0.042) and peripheral bleb areas (P=0.042) and peripheral bleb areas (P=0.042) and peripheral bleb areas (n = 88) patients achieved average vascular scores of less than 2.5 (P=0.042) and peripheral bleb areas (n = 88) patients achieved average vascular scores of less than 2.5 (vs. 94%; P=0.042) and peripheral bleb areas (. CONCLUSION: Topical bevacizumab gives a better vascularity profile at one year, but the studied routes appear equally safe and do not seem to affect the outcome in any other way.

Sustained Intraocular Pressure Rise after the Treat and Extend Regimen at 3 Years: Aflibercept versus Ranibizumab.

PURPOSE: To determine the risk factors associated with sustained intraocular pressure (IOP) rise in patients enrolled in the treat and extend (T&E) protocol receiving aflibercept/ranibizumab therapy for 3 years. DESIGN: Retrospective, observational chart review. Setting. Multicentric. Patients. 789 patients (1021 eyes; 602 males) enrolled in T&E using aflibercept/ranibizumab for diabetic macular edema (DME), wet age-related macular degeneration (AMD), or macular edema in retinal vein occlusion (RVO). Intervention. The history, examination (clinical and special investigations), and treatment records were thoroughly scrutinized. Sustained IOP rise was defined as a rise in IOP above baseline by ≥6 mmHg and/or >24 mmHg on 2 or more consecutive visits. The Wilk-Shapiro test was used for confirming normality of data. The Mantel-Haenszel test and generalized estimating equations were used to analyse multicentric data as well as to analyse data from both eyes of the same patients in the event that both eyes were under therapy. The relative risk, chi-square test (with and without Yates' correction), and univariate and multivariate analysis were used wherever appropriate. Statistical significance was set at P < 0.05. The primary outcome measure was the determination of risk factors for sustained IOP rise with ranibizumab/aflibercept therapy. Secondary outcome measures included determining the incidence of IOP rise (short term and sustained), visual field, and retinal nerve fibre layer (RNFL) changes. RESULTS: The mean follow-up was 42.4 months. Male gender, South Asian ethnicity, older age, presence of AMD and vein occlusion, use of ranibizumab, higher number of injections, narrow angles, switch to bevacizumab/ranibizumab, and preexisting glaucoma were associated with sustained IOP rise. No significant visual field and RNFL changes were seen. The overall incidence was 8.91%. No patient required filtering surgery. No patient with IOP rise returned to baseline. CONCLUSION: IOP rise is an important consideration as the chronicity of the condition can eventually lead to glaucomatous changes in eyes with already compromised vision. Follow-ups and use of appropriate therapy can be determined correspondingly.

Work-life balance among female dermatologists.

BACKGROUND: Female dermatologists often face the challenges of balancing a rewarding medical career with duties of home life and childrearing. Excessive responsibility at home or work can introduce barriers to balance and prove detrimental to the health and wellness of the physician. OBJECTIVE: We aim to perform a needs assessment through a series of survey questions with regard to home and work responsibilities and impacts on mental health. METHODS: Survey participants were selected from the Women's Dermatologic Society through an e-mail invitation with a link to an anonymous survey tool and a paper questionnaire at the Women's Dermatologic Society Forum in February 2019 in Dallas, Texas. The survey included 20 questions with regard to household responsibilities, child care, clinical responsibilities, specialty education, and impacts on personal time, sleep, and overall sense of well-being. There were a total of 127 respondents. RESULTS: Eighty-five percent of physicians in our cohort are currently married. A large percent of respondents utilized hired household help in the form of nannies to perform chores. Spousal contribution was emphasized in this cohort and often highlighted as an important factor in maintaining home life duties. CONCLUSION: The professional women in our cohort may be balancing work and life at the expense of personal physical and mental health with little time to exercise and fewer hours of sleep per night.

The use of topical Nitrosomonas eutropha for cosmetic improvement of facial wrinkles.

BACKGROUND: Both topical and oral probiotics are becoming widely used. There is increasing interest in the cosmetic potential in topical probiotics. Nitrosomonas eutropha is an ammonia-oxidizing bacteria. AIM: The purpose of this study was to assess whether there is any improvement in facial wrinkles with the use of Nitrosomonas eutropha, a topical probiotic. METHODS: In this prospective study, high-resolution photographs were obtained in twenty-nine participants at baseline and after using topical Nitrosomonas eutropha for seven days. RESULTS: There was a significant difference in wrinkle depth and severity in the high concentration probiotic group. There was also a statistically significant improvement in pigmentation of the forehead and glabella in the higher concentration group. CONCLUSIONS: Nitrosomonas eutropha may have aesthetic benefits in terms of reducing the appearance of wrinkles. Larger studies with longer treatment and follow-up periods are required.

Validating a Quality-of-Life Instrument for Allergic Contact Dermatitis.

BACKGROUND: Contact dermatitis is a prevalent condition that has a significant impact on quality of life (QoL). Although many generic dermatological QoL instruments exist, none were developed by and for patients with allergic contact dermatitis (ACD). OBJECTIVE: The aim of the study was to create and validate a reliable QoL instrument specific for the ACD population. METHODS: We identified QoL items specific to ACD through a series of qualitative interviews with ACD patients and experts. We created a 17-question survey that queries the patient across the following 3 major domains: symptoms, functioning, and emotions. We used statistical methods to evaluate the reliability and validity of this tool. RESULTS: Ninety patients with relevant positive results on patch testing completed the novel ACD instrument and the Skindex-29. This instrument exhibited reliability and validity in individuals with ACD and was more sensitive than the generic tool Skindex-29. CONCLUSIONS: This novel instrument is the first tool developed specifically to assess the unique impacts of ACD on QoL. Providers can reliably use this index to assess the specific aspects of the disease most problematic for the ACD patient and use this information to more properly inform counseling and management.

Allergic Contact Dermatitis of the Vulva.

Allergic contact dermatitis is an important diagnostic consideration in the evaluation of patients presenting with vulvar complaints. The high prevalence of contact sensitization in the vulvar region is likely multifactorial. We review the extant literature regarding key predisposing factors in the pathogenesis of vulvar allergic contact dermatitis, as well as the most commonly implicated allergens as identified by a number of retrospective studies and case series. On the basis of our findings, we provide diagnostic and therapeutic recommendations for practicing clinicians.

Progestins and acne vulgaris: a review.

The role of exogenous progestin in the development of acne is unclear. Progestins are known for their androgenic potential, but newer generations of progestins have low or anti-androgenic activity. This review will evaluate the association between progestins found in hormonal long-acting reversible contraceptives (intrauterine devices and subdermal implants) and acne, as well as the role of oral contraceptives in acne management. Our review demonstrates that the cause and effect relationship between progestins and acne is difficult to establish and future studies that seek to understand how progestins modulate acne are necessary.

Pustular psoriasis of pregnancy: current perspectives.

Pustular psoriasis of pregnancy (PPP) is a life-threatening condition for both the pregnant mother and fetus, and must be efficiently and accurately diagnosed and treated. This condition has historically been classified as a unique, separate dermatosis of pregnancy. However, current opinion and data suggest that it may be a variant of generalized pustular psoriasis. PPP typically occurs in the third trimester and is characterized by widespread coalescent pustules, desquamation, and systemic symptoms. Clinical features and histopathologic evaluation aid in diagnosis. Treatments during pregnancy include high-dose corticosteroids, cyclosporine, narrow-band ultraviolet B radiation, infliximab, granulocyte and monocyte adsorptive apheresis, and systemic antibiotics. Both the mother and fetus should be closely monitored with appropriate laboratory studies for the duration of the pregnancy and postpartum.

Emerging Therapies for Acne Vulgaris.

As we gain a greater understanding of acne pathogenesis, both new agents as well as new uses for established drugs are being considered for the treatment of acne vulgaris. Multiple clinical trials assessing new formulations or combinations of established acne treatments have been conducted, and novel uses of antimicrobials such as modified diallyl disulfide oxide and nitric oxide are being assessed in clinical trials. There are also a multitude of new therapies currently being studied that target the inflammatory cascade of acne pathogenesis, including sebosuppressive and anti-inflammatory phytochemicals, and  small molecule inhibitors targeting sebaceous glands and enzymes, among others. Laser and light therapy is also being modified for the treatment of acne through combination methods with metal nanoshells and vacuum assistance. Probiotics have gained popularity in medicine as greater knowledge of the microbiome and its effects on multiple organ systems is being elucidated. Studies describing the positive effects of certain ammonia-oxidizing bacterial strains in the regulation of the skin's inflammatory response are ongoing. Therapies for acne are constantly evolving and current gold-standard acne therapy may be supplemented with novel treatment modalities in the near future.

The metabolomics of psoriatic disease.

Metabolomics is an emerging new "omics" field involving the systematic analysis of the metabolites in a biologic system. These metabolites provide a molecular snapshot of cellular activity and are thus important for understanding the functional changes in metabolic pathways that drive disease. Recently, metabolomics has been used to study the local and systemic metabolic changes in psoriasis and its cardiometabolic comorbidities. Such studies have revealed novel insights into disease pathogenesis and suggest new biochemical signatures that may be used as a marker of psoriatic disease. This review will discuss common strategies in metabolomics analysis, current findings in the metabolomics of psoriasis, and emerging trends in psoriatic metabolomics.
