Fecal calprotectin - a valuable predictor of microscopic colitis.

OBJECTIVE: Microscopic colitis (MC) has been of major concern worldwide due to its relapsing and remitting nature of chronic diarrhea. Quality of life of patients suffering from this disease is quite debilitating. PATIENTS AND METHODS: In order to understand the role and importance of fecal calprotectin (FC) we performed a statistical analysis on the patients suffering from chronic diarrhea and admitted to our hospital from 2014 to 2020, and who were prescribed Loperamide (Imodium) or Budesonide or a combination of both and had undergone FC detection test. RESULTS: FC was found to be significantly correlated to the age, alcohol consumption and beta blocker use. A high level of the FC concentrations increases the chances of having flare-ups of diarrhea episodes making the quality of life of such patients worse. CONCLUSIONS: FC concentrations should be monitored frequently and precautionary measures to avoid a relapse should be aimed. Measures to improve quality of life, should be of prime concern. In-depth research is required to better understand MC and to find better treatment options which can be used on a long-term basis, instead of anti-motility drugs which are able to control the acute episodes, but when discontinued result in an increased tendency to have relapses.

Implication of wide surgical excision in minimizing positive margins and consequential secondary excision - a retrospective comparative study involving 106 basal cell carcinoma cases.

OBJECTIVE: The use of current surgical techniques in the management of skin cancers that are not amenable to other treatment options has become the cornerstone of dermatological surgical intervention. Among the many benign lesions and malignant lesions, such as squamous cell carcinomas, melanomas, and Merkel cell carcinomas, the tumors that are commonly excised surgically are the basal cell carcinomas (BCC). Although the majority of BCC lesions spread locally and are rarely metastatic, these lesions may recur, especially, if the excised tissue consists of positive surgical margins. As BCC lesions are more common on the head, face, and neck regions, inadvertent positive margin excisions to help avoid major disfigurement of the regions may contribute to their recurrence. Trichoepithelioma (TE) is a benign tumor that bears a close resemblance to BCC, and therefore, clinicians encounter difficulty in differentiating between TE and BCC lesions. Clinicians have to rely on histopathology and immune-histochemical markers to rule out TE. This differentiation is crucial to make a definitive diagnosis of BCC and subsequently, employ a more aggressive surgical excision approach to treat this invasive tumor as compared with TE. Our focus in this article is to highlight only the surgical excision management of local and or locally invasive BCCs and report the success rate of our hospital's Dermato-venereology clinic (DVC) in Timisoara, Romania. This article highlights the role of an appropriate wide local lesion excision (5 mm) with negative surgical margins in the prevention of further surgical interventions, be it for corrective or esthetic reasons. PATIENTS AND METHODS: This is a retrospective study that summarizes the evaluation of 120 lesions from 106 patients who were treated for BCCs at DVC (University Hospital), using a wide surgical excision method.  Following the Romanian Society of Dermatologists guidelines, local non-aggressive BCC lesions were excised with margins of 5 mm and up to 1 cm for the aggressive sclerosing subtype. RESULTS: The results of the audit of a sample of 120 lesions from 106 patients demonstrated that none of the surgically treated patients had recurrences and only 23 (19.16%) had positive surgical margin lesions. Out of these, 17 (73.91%) lesions underwent second surgical excision, while only three (13.04%) showed the presence of a residual tumor. The evaluation results may encourage dermatologists worldwide to make appropriately sized excision, especially in regions other than the head and neck, to avoid positive surgical margins and eliminate the need for consequent surgery. CONCLUSIONS: For a better post-surgical prognosis of BCC, the authors recommend the practice of a wide margin excision (5 mm) during the primary surgery to avoid secondary surgery, especially if the tissue in the region is not sparse and chances of causing major disfigurement are minimal. As our findings suggest, only a few cases have the presence of residual tumor in the second surgery, hence authors also advocate the necessity to inform the patients about the merits of a second surgery, clearly mentioning the possibility of the absence of tumor even in the presence of positive margin.

Selecting the right anticoagulant for stroke prevention in atrial fibrillation.

OBJECTIVE: The embolization of thrombi formed within the atria can occur in any form of atrial fibrillation (AF), i.e., paroxysmal, persistent, or permanent. Although ischemic stroke is the most frequent embolic event associated with AF, embolization to other sites in the pulmonary and systemic circulations may occasionally occur. To avert the risk of embolization, long-term oral anticoagulation therapy is recommended for all AF patients if the CHA2DS2-VASC score is at least 1 for men and at least 2 for women. Since anticoagulant therapy is associated with an increased risk of bleeding, the choice of oral anticoagulant agent should be made by careful consideration of the benefit-to-risk ratio. The use of a newer class of direct oral anticoagulants (DOACs) as an alternative to the anti-vitamin K (AVK) anticoagulants (warfarin, acenocumarol, etc.) can help mitigate the need for periodic monitoring of International Normalized Ratio (INR) and adverse bleeding events that are commonly associated with the use of AVK anticoagulants. Though the use of DOACs (dabigatran, rivaroxaban, edoxaban, apixaban, etc.) is gaining ground due to their relative safety profile and the low overall cost, quite a few clinicians remain skeptical about their use. PATIENTS AND METHODS: Our objective was to evaluate the risk of thromboembolism, stroke, neuropsychiatric illness, depression, and dementia, in patients with non-valvular atrial fibrillation who have been treated with either acenocumarol or apixaban, as well as to see the inflammatory status (ESR) and levels of fibrinogen. Our team at Municipal Emergency University Hospital, Timisoara, Romania, conducted a retrospective study using the medical records of AF patients who were treated with either apixaban or acenocumarol between 2016-2019. We divided the patients into two groups and compared the groups for the aforementioned outcomes. RESULTS: AF patients who were prescribed apixaban had a lower rate of stroke and psychiatric illness compared to those on acenocumarol. No significant correlation was found in terms of risk of developing depression or dementia between the groups. CONCLUSIONS: Non-valvular AF patients on apixaban had lower rates of thromboembolic events than the patients on acenocumarol. This article will serve as a reminder of the positive health and financial outcomes of apixaban use, especially to those healthcare systems that are still oblivious to the decrease in economic burden and gain in quality-adjusted life years (QALY) by the long-term use of NOACS/ DOACS instead of the AVK anticoagulants.
