The presence of SteLL stimulated the cells to release pro-inflammatory cytokines (IL-17A, TNF-α, IFN-γ and IL-2) and also of IL-4, an anti-inflammatory cytokine that can prevent exacerbated inflammation. SteLL induced decrease in the secretion of NO. In conclusion, SteLL has biotechnological potential as an immunomodulator agent for use in studies employing cultures of immune cells. In addition, the anti-infectious and antitumor properties of the leaves may involve the immunomodulation property of SteLL. © King Abdulaziz City for Science and Technology 2020.Background Defensive medicine is becoming increasingly prevalent in the United States and is estimated to cost billions of dollars in excess healthcare spending. There is evidence that the practice of defensive medicine starts early in the medical career. Defensive medicine has been investigated among residents in high medico-legal risk specialties, but there is a paucity of information on its prevalence among internal medicine residents. Objective  To examine the prevalence and patterns of defensive medical practices among internal medicine residents. Methods We conducted an online survey among the residents of three internal medicine residency programs in the 2018-2019 academic cycle. We invited all internal medicine residents within the selected programs to participate through email and asked them to complete an electronic survey assessing defensive medical practices. Results A total of 49 out of 143 residents participated in the study (response rate 34.3%); 55% (n = 27) of the residents who participated considered the risk of being sued during residency to be low, compared to 40.8% (n = 20) who considered it to be moderate and 4.1% (n = 2) who considered it to be high. Defensive medical practices were found to be widely prevalent (40.0-91.3%) among internal medicine residents across all three clinical training stages. Assurance defensive practices were more common than avoidance practices. Conclusion Defensive medical practices, especially of the assurance type, were widely prevalent among our sample of internal medicine residents.

The overall burden of RA related pulmonary disease is underestimated due to the limitation of resources in underdeveloped countries. High-resolution computed tomography (HRCT) is an important tool used to diagnose different abnormalities in RA related interstitial lung disease (ILD). The objective of the study was to evaluate HRCT findings in patients of RA related ILD and categorize the radiological findings according to clinical findings. Method This descriptive prospective observational study was conducted at Mayo Hospital, Lahore from June 2014 to June 2015. Patients of RA suspected of lung disease after selection underwent HRCT chest on 128-slice Hitachi CT scanner (Hitachi Global, Tokyo, Japan) in the radiology department. Images were reconstructed and evaluated by experienced radiologists. Findings were recorded on a questionnaire. Data was analyzed on SPSS version 21 (IBM Corp, Armonk, US). Results Out of the 54 patients scanned, interlobular septal thickening was the most common finding found in 22 of the patients. Ground-glass opacification was recognized in 21 patients, honeycombing in nine and bronchiectasis in two patients. Regarding zonal predilection of disease pattern, lower zones of lungs were found involved in most of the cases. The disease was found to be bilateral in 15 patients. Based on these findings, usual interstitial pneumonitis (UIP) was diagnosed in six patients and non-specific interstitial pneumonitis (NSIP) in 14 others. Conclusion This study concluded that HRCT images are very useful in diagnosing interstitial lung disease related to rheumatoid arthritis.

It can be found incidentally on radiologic imaging or due to clinical symptoms. Patients may become apprehensive due to it mimicking new malignancy or recurrence of prior malignancy. Treatment is only recommended in symptomatic cases and biopsy is usually unnecessary. We present a case of a 70-year-old female status-post lung cancer resection who was found to have a lump at the inferior pole of her right scapula. She was seen by multiple different specialties and subsequently, a biopsy confirmed her mass to be consistent with ED. Since ED is a benign soft tissue tumor, educating physicians is of utmost importance to avoid pursuing unnecessary diagnosis and to thereby decrease the cost of care to the patient. see more Therapeutic excision should only be performed in symptomatic patients and observing these lesions in asymptomatic patients would be sufficient.

It is a carcinoma with high metastatic and recurrent potential; it has the same incidence in both sexes, and mainly affects the elderly. Its diagnosis, rather than clinical, is histological, and due to the rarity of the disease, it is a pathological challenge. There are no standardized treatment guidelines for porocarcinoma, but surgical resection with tumor-free margins is considered the basis of treatment, in addition to sentinel node biopsy under risk factors and individualization of each patient. For the metastatic form, chemotherapy and radiotherapy are the treatment of choice. Herein, we present the case of a man with eccrine porocarcinoma with extensive zosteriform skin metastasis and lymph node involvement, treated with chemotherapy and concomitant radiotherapy.
