There have been many studies on the adverse effects of coronavirus disease 2019 (COVID-19) vaccines but the urinary incontinence after COVID-19 vaccination is rare. Here, we report an 8-year-old boy presented to outpatient department, Thai Binh University of Medicine Hospital, Thai Binh, Vietnam with complaints of urinary incontinence for the past 2 weeks, following the first dose of the messenger RNA vaccine. He had no other abnormalities in clinical and laboratory exams. This clinical situation suggested vaccine side effects. No specific treatment was administered upon diagnosis without toilet and bladder training. Subsequent monitoring revealed a gradual reduction in symptoms over 2 months, with complete recovery achieved at the 14th week from the onset of symptoms, without necessitating any medical intervention. This case highlights the need for thorough evaluation and assessment of potential adverse effects following vaccination, including uncommon presentations.

UNASSIGNED: Malposition is a relatively rare complication associated with peripherally inserted central catheters (PICCs), particularly in cases of superficial femoral vein (SFV) catheterization. To the best of our knowledge, we are the first to report this rare case of SFV PICC malposition in the contralateral renal vein.
UNASSIGNED: An 82-year-old woman underwent bedside cannulation of the SFV for PICC under ultrasound guidance. Subsequent radiographic examination revealed an unexpected misplacement, with the catheter tip positioned toward the contralateral renal vein. After pulling out the catheter on the basis of the X-ray result, it was observed that the catheter retained its function.
UNASSIGNED: Although rare, tip misplacement should be considered in SFV PICC placement. Prompt correction of the tip position is crucial to prevent catheter malfunction and further catastrophic consequences. For critical patients receiving bedside SFV PICC insertion, postoperational X-ray is crucial for enhancing safety.

Acute pancreatitis has been considered a rare potential adverse effect of sodium-glucose co-transporter-2 inhibitors (SGLT-2is), a new class of medications recently approved for use as an add-on therapy in patients with poorly controlled type 2 diabetes mellitus as well as in individuals with heart failure (HF) and chronic kidney disease (CKD). SGLT-2i can effectively reduce cardiovascular mortality and the deterioration of renal function. There are only a few published cases of acute pancreatitis linked to SGLT-2i administration. Our case describes a 58-year-old male who presented to the emergency department with a clinical presentation of acute pancreatitis, with no known risk factors, who was recently started on therapy with dapagliflozin. Following thorough clinical and laboratory testing, the diagnosis of pancreatitis was associated with dapagliflozin. Upon discharge, dapagliflozin was discontinued with no further recurrence of epigastric pain.

UNASSIGNED: Cutaneous leishmaniasis is endemic in Iran.
UNASSIGNED: We sought to investigate the therapeutic outcomes and complications of treatment in patients with cutaneous leishmaniasis.
UNASSIGNED: This case series enrolled patients with smear-proven cutaneous leishmaniasis who visited our center in Iran from 2018 to 2019.
UNASSIGNED: In total, 36 patients were treated with intralesional meglumine antimoniate, intramuscular meglumine antimoniate, sodium stibogluconate, and amphotericin B. Overall, this treatment was effective in 81.8 percent of patients. Relapse and treatment failure occurred in 6.1 percent and 12.1 percent of patients, respectively. Treatment with intralesional meglumine antimoniate, intramuscular meglumine antimoniate, sodium stibogluconate, and amphotericin B yielded a clearance rate of 80.8 percent, 92.3 percent, 75 percent, and 85.7 percent, respectively. Clearance was associated with a shorter time interval between injections of intralesional meglumine antimoniate (p=0.006) and relapse was associated with a longer time interval between injections (p=0.018). The average number of side effects per patient for intralesional meglumine antimoniate, sodium stibogluconate, intramuscular meglumine antimoniate, and amphotericin B was 0.62, 1.4, 1.6, and 2.8, respectively. The most common side effect of intralesional meglumine antimoniate, intramuscular meglumine antimoniate, and amphotericin B was local pain, arthralgia, and hypokalemia, respectively.
UNASSIGNED: Low sample size was the limitation of this study.
UNASSIGNED: The cure rate of intramuscular meglumine antimoniate was higher than amphotericin B, which was higher than the cure rate of sodium stibogluconate. In patients treated with intralesional meglumine antimoniate, reducing the time interval between injections increased the clearance rate and decreased the rate of relapse.

Daptomycin (DAP) is a cyclic lipopeptide antibiotic with bactericidal activity against gram-positive bacteria. The most common adverse reaction is myotoxicity characterized by rhabdomyolysis. Other reported adverse reactions include gastrointestinal symptoms, skin lesions, bleeding, and pulmonary involvement. Neurotoxicity is rare and its mechanism remains partially elucidated. We report a case of confusion consistent with DAP-induced neurotoxicity. A 73-year-old obese man was treated with DAP 9 mg/kg for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia associated with foot osteitis and cervical posterior inter-apophyseal arthritis. On the fifth day of treatment, he developed spatial disorientation, and serum DAP concentrations were very high. DAP-induced neurotoxicity was suggested. His neurological status returned to normal after treatment was stopped. This observation describes a relationship between confusion and DAP that is favored by obesity. Clinicians should be alert for neurologic disorders associated with DAP. It is prudent to reduce doses in obese patients.

Xanthoma disseminatum (XD) is a rare, non-Langerhans cell histiocytosis. While treatment is notoriously difficult, 2-chlorodeoxyadenosine (cladribine) has recently emerged as a potential effective therapeutic option. Here, we describe the case of a 65-year-old male with XD who experienced significant cutaneous improvement after cladribine treatment. We also provide an updated literature review on cladribine use in patients with XD in light of reported adverse effects (AEs). While the efficacy of cladribine in XD is clear, no consensus exists for treatment duration and AE management. Hence, we strongly encourage interdisciplinary discourse involving dermatology and oncology in these cases.

UNASSIGNED: Omalizumab is an established therapy for allergic conditions, yet its neurological effects remain underexplored compared to other biological agents.
UNASSIGNED: A 45-year-old male with asthma developed acute quadriparesis one week after receiving the first dose of omalizumab. Electrophysiological studies have shown partial motor conduction block in multiple nerves, with reduced CMAP amplitudes and absent F-waves in others. CSF showed cyto-albuminous dissociation. The diagnosis was a variant of Guillain-Barré syndrome. Despite intravenous immunoglobulin (IVIG) therapy, the patient experienced persistent neuropathic symptoms.
UNASSIGNED: The patient presented with acute quadriparesis devoid of sensory or cranial nerve involvement, suggestive of a variant of Guillain-Barré syndrome (GBS) known as acute motor conduction block neuropathy (AMCBN). Electrophysiological studies have indicated conduction block without demyelination, implicating axonal degeneration. Despite negative findings for common etiologies, the temporal association between omalizumab administration and symptom onset suggests a potential link, supported by criteria for drug-induced illness. Conflicting evidence exists regarding omalizumab\'s neurological effects, with proposed mechanisms including autoimmune reactions and mast cell dysfunction. Comparisons to TNF-α antagonists highlight similar neuropathy patterns, indicating a need for further research to clarify omalizumab\'s neurotoxicity.
UNASSIGNED: In conclusion, while omalizumab holds promise for allergic conditions, including chronic urticaria, its potential impact on peripheral nerves necessitates vigilance among clinicians. Further studies are imperative to ascertain the risk-benefit profile and elucidate underlying mechanisms and risk factors of neurological complications associated with omalizumab therapy.

UNASSIGNED: In Malaysia, following extensive COVID-19 vaccination, Hospital Kuala Lumpur reported an increase in cutaneous reactions post-immunisation. To understand this, a case-control study was initiated to identify potential risk factors.
UNASSIGNED: This registry-based, unmatched case-control study encompasses all adverse event following immunisation (AEFI) reports associated with COVID-19 vaccines, received by the Department of Pharmacy at Hospital Kuala Lumpur through the Malaysian Adverse Drug Reactions Advisory Committee (MADRAC) AEFI reporting forms. Twenty-four potential risk factors were evaluated, including demographic information, medical history, food allergies, COVID-19 vaccination history and prior SARS-CoV-2 infection, were evaluated using MADRAC AEFI reporting forms. Odds ratio (OR) with 95% confidence interval (CI) were estimated using univariable and multivariable logistic regression.
UNASSIGNED: Cutaneous reactions were more frequent in middle-aged females, especially after the first COVID-19 vaccine dose. These reactions, primarily mild and generalised, included pruritus and urticaria. Notably, 52% were delayed reactions (more than 4 h post-vaccination). Factors associated with increased risk of cutaneous reaction following COVID-19 immunisation included history of seafood and shellfish allergy (adjusted odds ratio [adjOR]: 2.11; 95% CI: 1.12, 3.96; P = 0.020), history of vaccine allergy (adjOR: 4.07; 95% CI: 1.44, 11.54; P = 0.008), past dermatological diseases (adjOR: 5.48; 95% CI: 2.03, 14.78; P = 0.001), and past medication allergy (adjOR: 2.12; 95% CI: 1.36, 3.31; P = 0.001).
UNASSIGNED: Self-reported histories of allergies to vaccines, foods or medications were found to increase the likelihood of cutaneous reactions following COVID-19 vaccination. These reactions, which were predominantly mild, did not hinder the administration of the second vaccine dose. The majority of reactions occurred after the first dose, manifesting as generalised pruritus and urticaria. They were effectively managed with oral antihistamines and low-dose corticosteroids, thereby avoiding the need for hospitalisation.

UNASSIGNED: Bleomycin is a glycopeptide antibiotic with outstanding anti-tumor effects. A major adverse effect of bleomycin is lung fibrosis. However, the development of cataracts as a severe adverse effect has not been reported.
UNASSIGNED: Herein, we describe the first case of cataract induced by bleomycin therapy in a 22-year-old male with testicular cancer. After surgical intervention and following five successive chemotherapy cycles of the BEP regimen, including bleomycin, etoposide and cisplatin, the patient reported a gradual painless loss of vision, with substantial decline in visual ability, especially in the right eye. Following comprehensive eye examinations, a cataract was diagnosed. Eventually, the patient underwent phacoemulsification and received replacement of the intraocular lenses.
UNASSIGNED: Bleomycin can cause cataracts, which induces a significant loss of vision. Therefore, clinicians should observe early symptoms and properly adjust treatment to prevent aggravation of symptoms.

BACKGROUND: High-dose vitamin C treatment (HVCT) can reduce the adverse effect of chemotherapy and enhance the effect of antitumor therapy, which has been considered one of the safest alternative treatments. However, the severity of its adverse effects may have been underestimated. The most serious adverse effect is hemolysis, which may result in acute kidney injury or death. Although glucose-6-phosphate dehydrogenase (G6PD) deficiency is considered to be the main cause, the probability and pathological mechanism are not completely understood, leading to a lack of effective and standardized treatment methods.
METHODS: Two patients with colorectal cancer developed hemolytic anemia after using 1 g/kg HVCT. In contrast to previous cases, the lowest hemoglobin level in the two cases was < 50 g/L, which was lower than previously reported. This may be because Case 1 had chronic hepatitis B for many years, which caused abnormal liver reserve function, and Case 2 had grade II bone marrow suppression. Both patients improved and were discharged after blood replacement therapy. Our cases had the most severe degree of hemolysis but the best prognosis, suggesting that our treatment may be helpful for rescue of drug-induced hemolysis. This is the first review of the literature on hemolysis caused by HVCT, and we found that all patients with G6PD deficiency developed hemolysis after HVCT.
CONCLUSIONS: G6PD deficiency should be considered as a contraindication to HVCT, and it is not recommended for patients with bone marrow suppression, moderate-to-severe anemia, hematopoietic abnormalities, or abnormal liver and kidney function. Early blood purification and steroid therapy may avoid acute kidney injury or death caused by HVCT-related hemolytic anemia.
