The current potential of AI in dermatopathology is to supplement diagnosis, and dermatopathologist guidance is essential for the development of useful deep learning algorithms. Herein, the recent progress of AI in dermatopathology is reviewed with emphasis on how deep learning can influence diagnosis, education, and research.

Tuberculosis (TB) in children is challenging to diagnose due to its non-specific symptoms and difficulties in obtaining confirmatory laboratory results. This study aimed to compare the treatment outcomes of confirmed and non-confirmed TB in children.

The medical records of children aged ≤ 15 years diagnosed with TB at Songklanagarind Hospital from January 2007 to December 2018 were examined. The TB cases were classified into three groups, confirmed cases (positive culture and/or polymerase chain reaction), probable cases (positive histopathological and/or acid-fast bacilli results) and presumptive cases (clinical manifestations and imaging findings compatible with TB and good response to anti-TB drugs but without microbiological confirmation).

Of 177 children, 66 (37.3%) had a confirmed diagnosis, 57 (32.2%) a probable diagnosis, and 54 (30.5%) a presumptive diagnosis. The successful treatment rates of the confirmed, probable and presumptive TB groups were 80.3%, 87.7% and 92.6%, respectively (p = 0.21). Of the 54 presumptive cases, a history of household contact with TB led to a diagnosis of asymptomatic pulmonary TB in 10 (18.5%) cases. Patients with a presumptive diagnosis were less likely to have disseminated and/or miliary TB (1.9% vs. 7.0% of probable vs. 22.7% of confirmed, p < 0.01).

Only one-third of the study patients had a confirmed TB diagnosis. The successful treatment and mortality rates did not significantly differ among the three groups. To increase the detection rate of early diagnosis of childhood TB, physicians should perform active TB contact investigations in household members of the index case.

Tumor necrosis factor inhibitors (TNFis) may be administered at a reduced dose to patients with ankylosing spondylitis (AS) for various reasons. However, in practice, there is insufficient evidence of how the dose reduction of TNFi is implemented and the amount of medical costs it reduces. In this study, we investigated treatment patterns among patients with AS who were administered various TNFis. The effect on medical costs related to AS was also investigated using Korea's insurance claims database.

From the insurance claims database of the Health Insurance Review & Assessment Service in South Korea, patients with AS newly treated with TNFis (etanercept, adalimumab, golimumab, and infliximab) between July 1, 2013, and June 30, 2016, were enrolled. Patients treated with the TNFis were followed up for 2years. Treatment patterns (continuation and discontinuation of TNFi) and dose reduction (< 50% of recommended dose) in patients who continued treatment were analyzed and compared among the TNFi groupsch TNFi. Additionally, the dose reductions significantly reduced the medical costs associated with AS, that is, from 24.85 to 35.52% of the total medical expenditure.The danger of Sclerotium cepivorum lies in the strength of its survival structure sclerotia. Sclerotia comprising hardened mycelium contains food reserves that allow it to remain dormant for long period, which makes the sclerotia-infested soil useless to grow any crop of the Allium species, including onion and garlic. This paper would be the first report on the application of two-photon fluorescence microscopy to the analysis of the structure of sclerotia from S. cepivorum. For this study and, in order to test the method, two different types of sclerotia were used (1) sclerotia isolated from naturally infested soil and (2) sclerotia produced in vitro (from 20-day-old cultures). Both types of sclerotia were processed by cryopreservation and eight µm histological cuts were used to obtain an autofluorescence image. For both sclerotia, the fluorescence spectrum has three peak signals at their wall. Sclerotia from infested soil presented fluorescence peaks at 400-436, 436-475, and 515-575 nm, while signals from sclerotia produced in vitro presented fluorescence peaks at 400-442, 500-600, and 655-700 nm. Peaks at the violet electromagnetic region (400-436 and 400-442) are like that of the signals reported by the melanin. This study showed that two-photon microscopy is a novel and valuable tool for the study of sclerotia structure and their fluorescence signal, and the possibility of using it as a specific marker to direct detection in the field should be explored.Double sex and mab-3-related transcription factor 1 (Dmrt1), which is expressed in goat male germline stem cells (mGSCs) and Sertoli cells, is one of the most conserved transcription factors involved in sex determination. Bomedemstat In this study, we highlighted the role of Dmrt1 in balancing the innate immune response in goat mGSCs. Dmrt1 recruited promyelocytic leukemia zinc finger (Plzf), also known as zinc finger and BTB domain-containing protein 16 (Zbtb16), to repress the Toll-like receptor 4 (TLR4)-dependent inflammatory signaling pathway and nuclear factor (NF)-κB. Knockdown of Dmrt1 in seminiferous tubules resulted in widespread degeneration of germ and somatic cells, while the expression of proinflammatory factors were significantly enhanced. We also demonstrated that Dmrt1 stimulated proliferation of mGSCs, but repressed apoptosis caused by the immune response. Thus, Dmrt1 is sufficient to reduce inflammation in the testes, thereby establishing the stability of spermatogenesis and the testicular microenvironment.

To analyze the literature on current conservative treatment options for Peyronie's disease (PD).

Conservative therapy with intralesional collagenase clostridium histolyticum (CCH) is safe and efficacious in either the acute or chronic phases of PD. Combination treatment with penile traction therapy (PTT) can produce even better results. While most PTT devices require extended periods of therapy up to 8h per day, the RestoreX® device can be effective at 30-90min per day. A variety of conservative therapies are available for treatment of PD. The available literature does not reveal any treatment benefit of oral therapies. Intralesional therapy is the mainstay conservative treatment of PD. Intralesional CCH therapy is the first Food and Drug Administration-approved intralesional therapy and represents the authors' preference for medical therapy. The most effective conservative management of PD likely requires a combination of therapies.
