    Abstract The current Coronavirus disease outbreak requires that physicians work in collaboration with other physicians especially in intensive care and emergency units. To fight against this new disease, whose pathogenesis, effects, and results have not been clearly demonstrated, especially in patients with the pre-existing chronic disease, requires special expertise and perspectives. Due to the need for dynamic glucocorticoid treatment at different stages of the disease in patients with adrenal insufficiency, the existence of reports indicating that "coronavirus disease 2019" also affects the adrenal reserve, and the use of glucocorticoids also in advanced stages in patients with Coronavirus disease require this issue to be emphasized with precision. Herein, treatment of the pre-existing adrenal insufficiency in patients with actual Coronavirus disease and the effects of the this critical disease on the adrenal gland have been reviewed.

    Abstract Felodipine is a calcium channel blocker with antioxidant and anti-inflammatory properties. Researchers have stated that oxidative stress and inflammation also play a role in the pathophysiology of gastric ulcers caused by nonsteroidal anti-inflammatory drugs. The aim of this study was to investigate the antiulcer effect of felodipine on indomethacin-induced gastric ulcers in Wistar rats and compare it with that of famotidine. The antiulcer activities of felodipine (5 mg/kg) and famotidine were investigated biochemically and macroscopically in animals treated with felodipine (5 mg/kg) and famotidine in combination with indomethacin. The results were compared with those of the healthy control group and the group administered indomethacin alone. It was observed that felodipine suppressed the indomethacin-induced malondialdehyde increase (P<0.001); reduced the decrease in total glutathione amount (P<0.001), reduced the decrease superoxide dismutase (P<0.001), and catalase activities (P<0.001); and significantly inhibited ulcers (P<0.001) at the tested dose compared with indomethacin alone. Felodipine at a dose of 5 mg/kg reduced the indomethacin-induced decrease in cyclooxygenase-1 activity (P<0.001) but did not cause a significant reduction in the decrease in cyclooxygenase-2 activity. The antiulcer efficacy of felodipine was demonstrated in this experimental model. These data suggest that felodipine may be useful in the treatment of nonsteroidal anti-inflammatory drug-induced gastric injury.

    Abstract Purpose: Ribociclib is a CDK4/6 inhibitor approved for the treatment of breast cancer; it inhibits the activity of CDK4/6 by competitively binding to adenosine 5'-triphosphate (ATP) binding sites. Although generally well-tolerated, ribociclib has been connected to a number of serious dermatologic complications. This study explored the effects of ATP on ribociclib-induced skin damage.
    Materials and methods: Using a rat model, ATP 25 mg/kg was injected intraperitoneally in the ATP + Ribociclib (ATR) group (
    Results: In the histopathological evaluation of the RCB group, dermal necrosis, degeneration in hair follicles, and pycnosis in keratinocytes were observed. Only mild degeneration was observed in the ATR group; the HC group had a normal histological appearance. The malondialdehyde (MDA) values were significantly higher and the superoxide dismutase (SOD), catalase (CAT), and total glutathione (tGSH) levels were significantly lower in the RCB group in comparison to the HC group (
    Conclusion: ATP may be useful in the treatment of ribociclib-induced skin damage.

    Abstract Sunitinib is a multitargeted kinase inhibitor that inhibits many receptor tyrosine kinases and has been used in the treatment of gastrointestinal stromal tumors, metastatic renal cell carcinoma, and pancreatic neuroendocrine tumors. In this study, the effects of sunitinib given to rats, both alone and after stress with cisplatin, were investigated. The animals were divided into four groups - (1) control group (C) administered interperitoneally with a single dose 0.9 % saline, (2) Cis group administered a single dose (7 mg/kg) of cisplatin, (3) Sun group administered 10 mg/kg sunitinib for seven days, and (4) Cis+Sun group administered 10 mg/kg sunitinib for seven days after a single dose (7 mg/kg) of cisplatin. After these applications, the rats were sacrificed, and blood and tissue samples were taken for biochemical and histopathological evaluations. Sunitinib did not show any effect on urea, creatine, and kidney IL1β and TGF-β3 expression levels when administered alone; it increased ALT, AST, and IL-38 levels. When sunitinib was given to the cisplatin-induced rats, it was observed that the increase in ALT, AST, and IL-38 levels increased more than the rats that was given only sunitinib. According to the data obtained, sunitinib does not cause a significant change in kidney tissue under both normal and stress conditions, while it creates stress in liver tissue. In addition, its toxicity in the liver becomes more certain as a result of its combination with cisplatin.

    Abstract Background: Sorafenib is a multikinase inhibitor currently used in the treatment of hepatocellular carcinoma, renal cell carcinoma and thyroid cancer.
    Objectives: The literature on this agent is scarce. This study aimed to evaluate the effects of sorafenib when administered to both healthy and cisplatin-induced rats.
    Material and methods: The animals were divided into 4 groups: 1) control group that received 0.9% saline intraperitoneally (C); 2) group administered a single dose (7 mg/kg) of cisplatin (Cis); 3) a group administered 20 mg/kg of sorafenib for 7 days (Sor); 4) group administered 20 mg/kg of sorafenib followed by 7 mg/kg of cisplatin for 7 days (Cis+Sor). All animals were sacrificed 7 days after the completion of their treatment arm, and serum and tissue samples were taken.
    Results: Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and interleukin 38 (IL-38) levels were increased in the Sor and Cis+Sor groups compared to the control group. When compared with the control group, serum urea, creatinine, kidney IL-1β, and tumor necrosis factor alpha (TNF-α) levels did not change in the Sor group. When compared to the Cis group, the levels of these parameters decreased in the Cis+Sor group.
    Conclusions: According to the data obtained, sorafenib caused liver toxicity when given to both healthy and cisplatin-induced rats. While sorafenib did not cause any significant changes in the kidneys when given to healthy rats, it had a healing effect in kidneys after stress induced by cisplatin.

    Abstract Background: Anastomotic leakage after rectal resection is a major complication which increases the rates of morbidity and mortality. A small number of patients with generalised peritonitis need radical surgical treatments. Stable patients with local peritonitis can be treated conservatively. The aim of this study is to evaluate the effects of transrectal vacuum treatment on the healing of low colorectal anastomotic leaks.
    Methods: Medical records of fourteen patients managed conservatively with transrectal vacuum treatment for anastomotic leakage after rectal resection between September 2015 and September 2018, were retrospectively reviewed. Anastomotic leakage was documented and evaluated with computerised tomography and rectosigmoidoscopy.
    Results: 10 of 14 patients had successful closure of the perianastomotic abscess cavity after a mean of 19 days of vacuum treatment. 2 patients in this group had stricture on the anastomotic site as a late complication which was successfully treated with repeated dilatations. 4 of 14 patients had eventually a permanent sigmoid colostomy.
    Conclusion: Our results suggest that transrectal vacuum treatment can be safely used to all stable patients without generalised peritonitis in the management of low colorectal anastomotic leakages.

    Abstract Objective: Patients who had curative treatment after a malignant disease frequently ask about their religious practices and especially Ramadan fasting. The aim of this study is to evaluate the survivors of gastric cancer patients whether they keep Ramadan fasting and the health conditions they experienced during the month of Ramadan. Materials and Methods: For this cross sectional observational study, first the files of patients who had gastrectomy due to malignancy between January 2011 and January 2018 in Gaziosmanpasa University Hospital were examined retrospectively. The surviving patients were scheduled for a meeting and a questionnaire was conducted in outpatient setting. Patients who were conceiving to fast in next Ramadan were invited for at least 2 visits again within one month before and one month after Ramadan. On their arrival, their weight was measured, laboratory test including albumin, haemoglobin, haematocrit, BUN and creatinine levels were obtained. Results: 11 (21%) of the 52 interviewed patients kept fasting in 2019 Ramadan. 5 of these patients were able to complete fasting (30 days) and 6 of them could partially (between 1-7 days). There was no weight loss in fasting patients after Ramadan (p> 0.05). In addition, no significant change was found in albumin, haemoglobin, haematocrit and creatinine values after Ramadan (p> 0.05). However increase in BUN level was statistically significant (p <0.05). Conclusion: Health professionals are likely to see fasting patients all over the world and they must be familiar with the physiological and psychological effects of fasting considering the spiritual and religious needs of the patients.

    Abstract Metformin-associated lactic acidosis in a diabetic patient is a rare and severe complication. The severity of the condition is associated with the underlying disease. The diagnosis may be delayed due to its rarity and the fact that its symptoms and signs are frequently confused with other pathologies. In such cases, generally, the underlying renal disease helps to establish the diagnosis. In this paper, we present the case of lactic acidosis in a patient without a serious underlying disease who was using metformin, ramipril and spironolacton for diabetes and hypertension. The level of blood creatinine was found to be 1.4 mg/dL. It should be kept in mind that metformin can cause life-threatening lactic acidosis, especially in patients using renin-angiotensin-aldosterone system blockers, even without a serious deterioration in renal functions.
