Challenges in Diagnosing and Managing Severe Hypernatremia in Patients With Major Depressive Disorder: A Case Report.

Hypernatremia, characterized by a plasma sodium concentration above 145 mmol/L, is frequently observed in critically ill patients, often due to factors such as gastrointestinal losses, dehydration, and diabetes insipidus. Psychiatric patients, particularly those with major depressive disorder, are also at risk of developing hypernatremia due to abnormalities in thirst sensation, mineralocorticoid excess, or medication side effects. Severe hypernatremia in psychiatric patients is associated with a high mortality rate, presenting challenges in diagnosis and management. The treatment of chronic hypernatremia (>48 hours) typically involves administering isotonic saline to hypovolemic patients until normalization of vital signs, followed by dextrose 5% in water (D5W) based on water deficit and losses. The goal is to decrease plasma sodium by 8-10 mmol/day. Acute hypernatremia (<48 hours) is corrected with a plasma sodium reduction of 1 mmol/L/hour in the first six to eight hours. While there are no clear guidelines for sodium correction in severe hypernatremia, the literature suggests a safe correction rate of 8-10 mmol/day for chronic hypernatremia and 1 mmol/L/hour for acute cases. In a specific case, a 51-year-old female with severe depression and reduced oral intake was admitted. She exhibited signs of dehydration and was found to have severe hypernatremia (191 mmol/L) with acute kidney injury. Treatment involved D5W, followed by D5W/half-normal saline at 150 mL/hr. Within 24 hours, her plasma sodium decreased to 178 mmol/L and gradually normalized to 143 mmol/L without neurological complications. This case highlights the challenges and underscores the importance of early recognition and management of severe hypernatremia in psychiatric patients. The primary treatment approach addresses water deficits and losses and administers D5W. Recent findings suggest that rapid correction of the condition is acceptable.

The Impact of an Intern's Clinical Guidebook on Easing the Transition of New Interns Into the United States Healthcare System.

This study explores the efficacy of an intern's clinical guidebook in facilitating the transition of categorical internal medicine interns into the United States healthcare system. New interns, particularly foreign medical graduates, face multifaceted challenges during their initial year of residency. The research, conducted at Ascension Saint Joseph Hospital in Chicago, employed a quasi-experimental pre-post design involving 20 interns. Participants were provided with an intern's clinical guidebook, and their knowledge was assessed through pre and post exams. Results demonstrated a statistically significant improvement in overall knowledge, with mean scores increasing from 65% to 77.37%. Subgroup analysis revealed similar improvements among both male and female interns. Data confidentiality and ethical considerations were prioritized, with participant data anonymized and stored securely. Despite limitations, this study highlights the guidebook's potential to enhance intern education and improve the quality of care provided during the crucial transition period. Further research is recommended to validate and extend these findings.

Case Report of Sotalol Induced IgA Vasculitis.

BACKGROUND: IgA vasculitis is the most common form of systemic vasculitis in children but can occur in adults. Inciting antigens include infections, drugs, foods, insect bites, and immunizations. Antibiotics and tumor necrosis factor (TNF) alpha inhibitors are the most common class of drugs that cause IgA vasculitis. Although sotalol and rivaroxaban have been documented to cause leukocytoclastic vasculitis, we have never come across any literature attributing IgA vasculitis to either drug. Additionally, Rocky Mountain spotted fever has not been associated with IgA vasculitis despite being described in cutaneous and systemic vasculitis cases. Here, we present a case of IgA vasculitis triggered by sotalol with challenging differentials, including a recent infection with Rocky Mountain spotted fever, malignancy, and rivaroxaban as possible triggers. CASE PRESENTATION: 68 yr old male with a history of lung cancer treated with resection and chemotherapy 5 years ago is currently in remission, and recently was started on sotalol and rivaroxaban for new-onset paroxysmal atrial fibrillation. He presented with diffuse petechial/purpural rash on the lower limbs, multiple joint pain, severe abdominal pain and rectal bleeds, hemoptysis, and renal dysfunction. IgG titers for RMSF were high. Punch biopsy of skin and renal biopsy were consistent with IgA vasculitis. Sotalol and rivaroxaban were stopped. The patient was treated with oral prednisone, and his condition relatively improved. CONCLUSION: Ig A vasculitis is mostly a self-limiting disease, but adults tend to have a severe course. It is important to diagnose early and identify a trigger. Removing the offending agent or treating the underlying infection is an important aspect of management.

Spatial distribution of breast cancer in Sudan 2010-2016.

BACKGROUND: Breast cancer is the most prevalent cancer among females worldwide including Sudan. The aim of this study was to determine the spatial distribution of breast cancer in Sudan. MATERIALS AND METHODS: A facility based cross-sectional study was implemented in eighteen histopathology laboratories distributed in the three localities of Khartoum State on a sample of 4630 Breast Cancer cases diagnosed during the period 2010-2016. A master database was developed through Epi InfoTM 7.1.5.2 for computerizing the data collected: the facility name, type (public or private), and its geo-location (latitude and longitude). Personal data on patients were extracted from their respective medical records (name, age, marital status, ethnic group, state, locality, administrative unit, permanent address and phone number, histopathology diagnosis). The data was summarized through SPSS to generate frequency tables for estimating prevalence and the geographical information system (ArcGIS 10.3) was used to generate the epidemiological distribution maps. ArcGIS 10.3 spatial analysis features were used to develop risk maps based on the kriging method. RESULTS: Breast cancer prevalence was 3.9 cases per 100,000 female populations. Of the 4423 cases of breast cancer, invasive breast carcinoma of no special type (NST) was the most frequent (79.5%, 3517/4423) histopathological diagnosis. The spatial analysis indicated as high risk areas for breast cancer in Sudan the States of Nile River, Northern, Red Sea, White Nile, Northern and Southern Kordofan. CONCLUSIONS: The attempt to develop a predictive map of breast cancer in Sudan revealed three levels of risk areas (risk, intermediate and high risk areas); regardless the risk level, appropriate preventive and curative health interventions with full support from decision makers are urgently needed.
