Review
Bronchial asthma (BA) continues to be a difficult disease to diagnose. Various factors have been described in the development of BA, but to date, there is no clear evidence for the etiology of this chronic disease. The emergence of COVID-19 has contributed to the pandemic course of asthma and immunologic features. However, there are no unambiguous data on asthma on the background and after COVID-19. There is correlation between various trigger factors that provoke the development of bronchial asthma. It is now obvious that the SARS-CoV-2 virus is one of the provoking factors. COVID-19 has affected the course of asthma. Currently, there is no clear understanding of whether asthma progresses during or after COVID-19 infection. According to the results of some studies, a significant difference was identified between the development of asthma in people after COVID-19. Mild asthma and moderate asthma do not increase the severity of COVID-19 infection. Nevertheless, oral steroid treatment and hospitalization for severe BA were associated with higher COVID-19 severity. The influence of SARS-CoV-2 infection is one of the protective factors. It causes the development of severe bronchial asthma. The accumulated experience with omalizumab in patients with severe asthma during COVID-19, who received omalizumab during the pandemic, has strongly suggested that continued treatment with omalizumab is safe and may help prevent the severe course of COVID-19. Targeted therapy for asthma with the use of omalizumab may also help to reduce severe asthma associated with COVID-19. However, further studies are needed to prove the effect of omalizumab. Data analysis should persist, based on the results of the course of asthma after COVID-19 with varying degrees of severity.

Immune-mediated diarrhea represents a serious complication of checkpoint inhibitor therapy, especially following ipilimumab-based treatment. Efficient diagnosis and control of diarrhea remains an ongoing challenge. We developed an accelerated management paradigm for patients with ipilimumab-induced diarrhea. Patients who developed significant diarrhea (>five loose stools/day) were presumed to be developing immune colitis. Therapy was interrupted and patients were treated with a methylprednisolone dose pack. If diarrhea was not completely resolved, high-dose steroids and infliximab were promptly added. Only non-responding patients underwent further evaluation for infection or other causes of diarrhea. A total of 242 patients were treated with ipilimumab-based regimens. Forty-six developed significant diarrhea (19%) and thirty-four (74.4%) had a rapid resolution of diarrhea following glucocorticosteroid and infliximab treatment. The median time to resolution of diarrhea was only 8.5 ± 16.4 days. Accelerated treatment for presumed immune-mediated diarrhea resulted in the rapid control of symptoms in the majority of patients. There were no intestinal complications or deaths. Immunosuppressive therapy for diarrhea did not appear to decrease the remission rate or survival. After the control of diarrhea, most patients were able to continue their planned immunotherapy. Further testing in 11/46 patients with unresponsive diarrhea revealed additional diagnoses, allowing their treatment to be adjusted.

Review
Calcium plays central roles in numerous biological processes, thereby, its levels in the blood are under strict control to maintain homeostatic balance and enable the proper functioning of living organisms. The regulatory mechanisms ensuring this balance can be affected by pathologies such as cancer, and as a result, hyper- or hypocalcemia can occur. These states, characterized by elevated or decreased calcium blood levels, respectively, have a significant effect on general homeostasis. This article focuses on a particular form of calcium metabolism disorder, which is hypercalcemia in neoplasms. It also constitutes a summary of the current knowledge regarding the diagnosis of hypercalcemia and its management. Hypercalcemia of malignancy is estimated to affect over 40% of cancer patients and can be associated with both solid and blood cancers. Elevated calcium levels can be an indicator of developing cancer. The main mechanism of hypercalcemia development in tumors appears to be excessive production of parathyroid hormone-related peptides. Among the known treatment methods, bisphosphonates, calcitonin, steroids, and denosumab should be mentioned, but ongoing research promotes progress in pharmacotherapy. Given the rising global cancer prevalence, the problem of hypercalcemia is of high importance and requires attention.

Successful Treatment of Steroid-Refractory Immune Thrombocytopenia in a Patient Developing Multiple Myeloma While on Immune Checkpoint Inhibitor Therapy for Lung Cancer: A Case Report.
Immune checkpoint inhibitor-related thrombocytopenia (irTCP) is a relatively rare immune-related adverse event (irAE); however, overall survival may worsen when it occurs. Prolonged use of high-dose steroids can diminish the effectiveness of immune checkpoint inhibitor (ICI) therapy on the primary disease because of T lymphocyte suppression, thus early tapering is necessary. We experienced a rare case of a 79-year-old male who concurrently developed irTCP and multiple myeloma (MM) during treatment with ICIs for lung adenocarcinoma. The patient exhibited severe thrombocytopenia and elevated serum IgA levels. Based on various tests, we diagnosed MM and irTCP. Despite administering the standard bortezomib plus dexamethasone (Bd therapy) treatment for MM, there was no response and the irTCP was steroid-resistant. Consequently, we administered a regimen including daratumumab (DPd therapy) for steroid-resistant irTCP and refractory MM, which resulted in a response. As a result, we were able to avoid prolonged use of high-dose steroids and the patient is stable without exacerbation of lung adenocarcinoma for 1 year and 5 months after the onset of MM. To our knowledge, there are no cases of MM developing during ICI treatment and this is the first case report in which daratumumab was effective for the treatment of irTCP.

BACKGROUND AND AIMS
Coronavirus disease (COVID-19)-related pneumonia is proposed to be an inflammatory process. The treatment currently includes supportive therapy and low-dose steroids. Anti-inflammatory drugs have been proposed to prevent cytokine storms and improve oxygenation in such cases. The study aimed to assess the efficacy of nebulized lignocaine in COVID-19 patients with pneumonia.
MATERIAL AND METHODS
This was an exploratory randomized double-blinded control trial conducted in COVID-19 patients with respiratory failure requiring oxygen therapy either by face mask or non-invasive mechanical ventilation. Patients included were of the age of more than 18 years of either gender. The patients were randomized to receive either lignocaine or distilled water nebulization. The outcomes assessed were PaO/FiO ratio, hemodynamics, respiratory parameters, and sequential organ failure score (SOFA).
RESULTS
The two groups were comparable concerning demographic variables. The PaO/FiO were significantly higher in the lignocaine group from day 2 onward. The SPO was significantly higher on day 3 in the lignocaine group and thereafter there was no significant difference. Other hemodynamic, respiratory parameters, and SOFA scores showed no difference in both the groups.
CONCLUSION
Lignocaine nebulization improved oxygenation in COVID-19 patients and can be used as adjunctive therapy along with other supportive medications.

Background and objective Morphea, or localized scleroderma (LS), is an autoimmune skin disorder characterized by inflammation and sclerosis. Its potential causes include infections, genetic predisposition, and trauma. The disease involves cycles of inflammation and fibrosis, leading to skin hardening and scarring, which can cause deformities if untreated. Research exploring the link between morphea and rheumatoid factor (RF), a marker associated with other autoimmune conditions, is ongoing. This study aimed to examine the less-explored role of RF, a marker typically linked to rheumatoid arthritis (RA), in the severity of morphea. It focused on assessing the levels of RF among morphea patients and its correlation with disease severity, intending to provide deeper insights into the condition and its management. Methods This study involved a simple randomized cross-sectional analysis to evaluate the role of the RF in measuring morphea severity among patients at the Dermatology and Venereology Department of Al-Sader Teaching Hospital from October 2022 to December 2023. We included participants with clinically and laboratory-confirmed morphea while excluding those with other autoimmune dermatological diseases, recent systemic steroid or immunosuppressive therapy, and pregnant women. The assessment of disease severity was done by utilizing the Localized Scleroderma Cutaneous Assessment Tool (LoSCAT). Statistical analyses were performed using SPSS Statistics version 27 (IBM Corp., Armonk, NY), with a significance threshold of p<0.05. Results Elevated RF levels were significantly associated with increased morphea severity, with severe cases showing higher RF levels (mean: 30.34 U/mL) compared to moderate (25.83 U/mL) and mild cases (21.56 U/mL) (p = 0.028). However, no significant correlation was found between RF levels and demographic factors such as age, gender, or occupation. Patients with high RF levels had a longer disease duration (mean: 57.15 years) compared to those with normal levels (25.83 years, p = 0.020). Significant differences were observed in lesion distribution on the back (p = 0.002). Logistic regression indicated that severe morphea patients were more likely to have elevated RF levels [odds ratio (OR): 1.158, p = 0.014]. Conclusions This study enriches our understanding of RF's role in morphea, revealing no significant correlation with demographic factors but suggesting its potential role in disease chronicity and severity.

Cocaine is a widely abused controlled substance. Cocaine use is associated with a myriad of side effects and a sequelae of consequences secondary to its harmful nature and potential adulterants, the most recently described and less known sequelae being leukoencephalopathy. In our case, we describe a 58-year-old male who presented to the ED with agitation and acute stroke-like symptoms with reported rapid onset. Cocaine induced toxic leukoencephalopathy is a diagnosis of exclusion, thus other etiologies of disease were ruled out in a full neurological and infectious workup; most importantly consisting of extensive brain imaging, alluding to the diagnosis of acute cocaine induced toxic leukoencephalopathy in an individual with a confirmed history of cocaine and cannabinoid abuse. Although there is no targeted therapy for the condition to our knowledge, we utilized a supportive approach to treatment in contrast to other reported treatment modalities which included the use of steroids, plasma exchange, and intravenous immunoglobulin. Furthermore, we describe the clinical evaluation and treatment throughout the patient's hospital course with his eventual marked improvement from initial presentation.

OBJECTIVE
This study aimed to evaluate the oncological and reproductive outcomes of fertility-preserving re-treatment in progestin-resistant endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) women who desire to maintain their fertility.
METHODS
Our study included 61 progestin-resistant EC/AEH patients. These patients underwent treatment with gonadotropin-releasing hormone agonist (GnRHa) solely or a combination of GnRHa with levonorgestrel-releasing intrauterine system (LNG-IUD) or aromatase inhibitor (AI). Histological evaluations were performed every 3-4 months. Upon achieving complete remission (CR), we recommended maintenance treatments including LNG-IUD, cyclical oral contraceptives, or low-dose cyclic progestin until they began attempting conception. Regular follow-up was conducted for all patients. The chi-square method was utilized to compare oncological and fertility outcomes, while the Cox proportional hazards regression analysis helped identify risk factors for CR, recurrence, and pregnancy.
RESULTS
Overall, 55 (90.2%) patients achieved CR, including 90.9% of AEH patients and 89.7% of EC patients. The median re-treatment time was 6 months (ranging from 3 to 12 months). The CR rate for GnRHa alone, GnRHa + LNG-IUD and GnRHa + AI were 80.0%, 91.7% and 93.3%, respectively. After a median follow-up period of 36 months (ranging from 3 to 96 months), 19 women (34.5%) experienced recurrence, 40.0% in AEH and 31.4% in EC patients, with the median recurrence time of 23 months (ranging from 6 to 77 months). Among the patients who achieved CR, 39 expressed a desire to conceive, 20 (51.3%) became pregnant, 11 (28.2%) had successfully deliveries, 1 (5.1%) was still pregnant, while 8 (20.5%) suffered miscarriages.
CONCLUSION
GnRHa-based fertility-sparing treatment exhibited promising oncological and reproductive outcomes for progestin-resistant patients. Future larger multi-institutional studies are necessary to confirm these findings.

The efficacy of immune checkpoint inhibitors (ICIs) has been widely recognized in several cancers and is now being used in the perioperative setting for lung cancer.We recently encountered an immune-related adverse event that has not been previously reported: thoracic lymphangitis, which occurred after postoperative ICI treatment for lung cancer. The patient complained of breathlessness and her condition rapidly progressed to hypoxia grade 3. Chest computed tomography revealed significant lymphostasis. With high-dose steroid treatment, the patient showed improvement.Therefore, as the frequency of neoadjuvant, adjuvant, and perioperative ICI use is expected to increase, it is crucial to understand and monitor this adverse event.

Prevalence of renal insufficiency and factors associated among selected cancer patients on chemotherapy at Ocean Road Cancer Institute in Tanzania: a cross-sectional study.
BACKGROUND
Cancer is among the leading cause of death worldwide. Chemotherapy is commonly used in cancer management and among the challenges in managing cancer patients is renal insufficiency (RI), which can be due to cancer or anticancer treatment and can be potentiated by different factors. Data regarding the prevalence of RI and associated factors in Tanzania is scanty. This study aims to assess the prevalence of RI and associated factors among selected cancer patients on chemotherapy.
METHODS
This analytical cross-sectional study was conducted at Ocean Road Cancer Institute (ORCI) in Dar es Salaam, Tanzania, from March to May 2023. The study included cancer patients on chemotherapy. Data was collected using semi-structured questionnaires whereby socio-demographics, clinical and laboratory data were recorded. Data was analyzed by using STATA version 15. Categorical data was presented as frequencies and percentages, and continuous data was summarized using means. A modified Poisson regression model was used to assess factors associated with RI. The p-values ≤ 0.05 was considered statistically significant.
RESULTS
Out of 354 patients, the majority (76.6%) were female. The enrolled patients' mean age was 53 ± 13.19 years. The proportion of cancer patients with RI was 62.2% with most (60%) having stage 2 and stage 3 (37.7%). Age, hypertension (HTN), human immunodeficiency virus (HIV), diabetes mellitus (DM) and non-steroidal anti-inflammatory drugs (NSAIDs) use were significantly associated with increased risk of RI (p ≤ 0.05).
CONCLUSION
This study showed that RI is common among cancer patients on chemotherapy. Age, HTN, DM, HIV and NSAIDS use were associated with RI. Close monitoring of kidney function is necessary for cancer patients with other factors associated with RI. Use of creatinine clearance (CrCl) rather than serum creatinine in estimating kidney function is important.
