Abstract
RATIONALE Botrychium ternatum ((Thunb.) Sw.), a traditional Chinese medicine, is known for its therapeutic properties in clearing heat, detoxifying, cough suppression, and phlegm elimination. It has been extensively used in clinics for the treatment of many inflammation-related diseases. Currently, there are no documented cases of rhabdomyolysis resulting from Botrychium ternatum intoxication. PATIENT CONCERNS A 57-year-old male presented with a complaint of low back discomfort accompanied by tea-colored urine lasting for 4 days. The patient also exhibited markedly increased creatine phosphate kinase and myoglobin levels. Prior to the onset of symptoms, the patient consumed 50 g of Botrychium ternatum to alleviate pharyngodynia. DIAGNOSES The patient was diagnosed with rhabdomyolysis due to Botrychium ternatum intoxication. INTERVENTIONS The patient underwent a substantial volume of fluid resuscitation, diuresis, and alkalization of urine, as well as correction of the acid-base balance and electrolyte disruption. OUTCOMES Following a 10-day treatment plan involving massive fluid resuscitation, diuresis, and alkalization of urine, the patient showed notable improvement in his lower back pain and reported the absence of any discomfort. Following reexamination, the levels of creatine phosphate kinase and myoglobin were restored to within the normal ranges. Additionally, no abnormalities were detected in liver or renal function. As a result, the patient was considered eligible for discharge and was monitored. CONCLUSIONS Botrychium ternatum intoxication was associated with the development of rhabdomyolysis. To manage this condition, it is recommended that patients provide massive fluid resuscitation, diuresis, alkalization of urine, and other appropriate therapeutic interventions. LESSON Currently, there are no known cases of rhabdomyolysis resulting from Botrychium ternatum intoxication. However, it is important to consider the potential occurrence of rhabdomyolysis resulting from Botrychium ternatum intoxication when there is a correlation between the administration of Botrychium ternatum and the presence of muscular discomfort in the waist or throughout the body, along with tea-colored urine. Considering the levels of creatine phosphate kinase and myoglobin, the diagnosis or exclusion of rhabdomyolysis caused by Botrychium ternatum intoxication should be made, and suitable treatment should be administered accordingly.

Abstract
BACKGROUND Retinoblastoma (Rb) is the most common intraocular malignancy in childhood, originating from primitive retinal stem cells or cone precursor cells. It can be triggered by mutations of the RB1 gene or amplification of the MYCN gene. Rb may rarely present with polydactyly. METHODS We conducted karyotype analysis, copy number variation sequencing, and whole-genome sequencing on the infant proband and his family. The clinical course and laboratory results of the proband's infant were documented and collected. We also reviewed the relevant literature. RESULTS A 68-day-old boy presented with preaxial polydactyly and corneal edema. His intraocular pressure (IOP) was 40/19 mmHg, and color Doppler imaging revealed vitreous solid mass-occupying lesions with calcification in the right eye. Ocular CT showed flaky high-density and calcification in the right eye. This was classified as an International Retinoblastoma Staging System group E retinoblastoma with an indication for enucleation. Enucleation and orbital implantation were performed on the child's right eye. Karyotype analysis revealed an abnormal 46, XY, 15pstk+ karyotype, and the mother exhibited diploidy of the short arm of chromosome 15. The Alx-4 development factor, 13q deletion syndrome, and the PAPA2 gene have been reported as potential mechanisms for Rb combined with polydactyly. CONCLUSION We report the case of a baby boy with Rb and polydactyly exhibiting a 46, XY, 15pstk+ Karyotype. We discuss potential genetic factors related to both Rb and polydactyly. Furthermore, there is a need for further exploration into the impact of chromosomal polymorphisms in Rb with polydactyly.

Abstract
PURPOSE Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome, also known as Barakat syndrome, is a rare autosomal dominant disease characterized by the triad of hypoparathyroidism, deafness, and renal abnormalities. The disorder is caused by the haploinsufficiency of the zinc finger transcription factor GATA3 and exhibits a great clinical variability with an age-dependent penetrance of each feature. We report two unrelated kindreds whose probands were referred to our outpatient clinic for further evaluation of hypoparathyroidism. METHODS The proband of family 1, a 17-year-old boy, was referred for severe hypocalcemia (5.9 mg/dL) incidentally detected at routine blood tests. Abdomen ultrasound showed bilateral renal cysts. The audiometric evaluation revealed the presence of bilateral moderate hearing loss although the patient could communicate without any problem. Conversely, the proband of family 2, a 19-year-old man, had severe symptomatic hypocalcemia complicated by epileptic seizure at the age of 14 years; his past medical history was remarkable for right nephrectomy at the age of 4 months due to multicystic renal disease and bilateral hearing loss diagnosed at the age of 18 years. RESULTS Based on clinical, biochemical, and radiologic data, HDR syndrome was suspected and genetic analysis of the GATA3 gene revealed the presence of two pathogenetic variants in exon 3, c.404dupC and c.431dupG, in the proband of family 1 and 2, respectively. CONCLUSION HDR syndrome is a rare cause of hypoparathyroidism and must be excluded in all patients with apparently idiopathic hypoparathyroidism. A correct diagnosis is of great importance for early detection of other HDR-related features and genetic counseling.

Critical care (London, England). 2024;(1):124
Abstract
Extracorporeal Carbon Dioxide Removal (ECCO2R) is used in acute respiratory distress syndrome (ARDS) patients to facilitate lung-protective ventilatory strategies. Electrical Impedance Tomography (EIT) allows individual, non-invasive, real-time, bedside, radiation-free imaging of the lungs, providing global and regional dynamic lung analyses. To provide new insights for future ECCO2R research in ARDS, we propose a potential application of EIT to personalize End-Expiratory Pressure (PEEP) following each reduction in tidal volume (VT), as demonstrated in an illustrative case. A 72-year-old male with COVID-19 was admitted to the ICU for moderate ARDS. Monitoring with EIT was started to determine the optimal PEEP value (PEEPEIT), defined as the intersection of the collapse and overdistention curves, after each reduction in VT during ECCO2R. The identified PEEPEIT values were notably low (< 10 cmH2O). The decrease in VT associated with PEEPEIT levels resulted in improved lung compliance, reduced driving pressure and a more uniform ventilation pattern. Despite current Randomized Controlled Trials showing that ultra-protective ventilation with ECCO2R does not improve survival, the applicability of universal ultra-protective ventilation settings for all patients remains a subject of debate. Inappropriately set PEEP levels can lead to alveolar collapse or overdistension, potentially negating the benefits of VT reduction. EIT facilitates real-time monitoring of derecruitment associated with VT reduction, guiding physicians in determining the optimal PEEP value after each decrease in tidal volume. This original description of using EIT under ECCO2R to adjust PEEP at a level compromising between recruitability and overdistention could be a crucial element for future research on ECCO2R.

BMC oral health. 2024;(1):362
Abstract
BACKGROUND AND OBJECTIVES The literature about oral manifestations and dental management in maple syrup urine disease (MSUD) is sparse. The aim of this report is to present a new case of MSUD with special emphasis on oral findings and to review the relevant literature. METHOD A case report of a 4-year-old boy with MSUD was described according to the CARE guidelines for describing case reports. Scoping review of relevant literature was performed, according to the PRISMA-ScR guidelines, by searching PubMed, Medline, Embase, and the grey literature for articles describing dental management and/or oral manifestations in MSUD. RESULTS The initial search identified 219 articles, but only 4 met the inclusion criteria. Rampant caries and plaque induced gingivitis were the main oro-dental findings in MSUD. Other oral findings included enamel hypoplasia, skeletal abnormalities, and abnormal oral behaviors. Disease-related factors appeared to play a major role in the development of the observed oral phenotype. CONCLUSION Oral health in MSUD seems to be influenced by the reliance on semi-synthetic diet and associated neurocognitive complications. Tailored oral health promotional interventions should be included in the multidisciplinary management of patients with MSUD.

Abstract
INTRODUCTION In rare occasions, coxsackievirus infections can cause serious illness, such as encephalitis and myocarditis. The immunotherapies of cancer could increase the risk of myocarditis, especially when applying immune checkpoint inhibitors. Herein, we report a rare case of Coxsackie B virus-induced myocarditis in a patient with a history of lymphoma. CASE PRESENTATION A 32-year-old woman was admitted to the hospital with recurrent fever for more than 20 days, and she had a history of lymphoma. Before admission, the positron emission tomography/computed tomography result indicated that the patient had no tumor progression, and she was not considered the cancer-related fever upon arriving at our hospital. Patient's red blood cell, platelet count, and blood pressure were decreased. In addition, she had sinus bradycardia and 3 branch blocks, which was consistent with acute high lateral and anterior wall myocardial infarction. During hospitalization, the patient had recurrent arrhythmia, repeated sweating, poor mentation, dyspnea, and Coxsackie B virus were detected in patient's blood samples by pathogen-targeted next-generation sequencing. The creatine kinase, creatine kinase MB, and N-terminal pro-brain natriuretic peptide were persistently elevated. Consequently, the patient was diagnosed with viral myocarditis induced by Coxsackie B virus, and treated with acyclovir, gamma globulin combined with methylprednisolone shock therapy, trimetazidine, levosimendan, sildenan, continuous pump pressors with m-hydroxylamine, entecavir, adefovir, glutathione, pantoprazole, and low-molecular-weight heparin. Her symptoms worsened and died. CONCLUSION We reported a case with a history of lymphoma presented with fever, myocardial injury, who was ultimately diagnosed with Coxsackie B virus-induced myocarditis. Moreover, pathogen-targeted next-generation sequencing indeed exhibited higher sensitivity compared to mNGS in detecting Coxsackie B virus.

Spontaneous resolution of an intrapericardial thrombus as a complication of pericardiocentesis in a neonate.
Crombez, J, Dewals, W, Muiño Mosquera, L, Martens, T, Van Damme, K, Bruyndonckx, L
Cardiology in the young. 2024;(4):924-926
Abstract
We present the case of a premature neonate with pericardial effusion secondary to extravasation of total parenteral nutrition from a mispositioned/migrated umbilical venous catheter. Emergency pericardiocentesis was complicated by an intrapericardial thrombus, which was managed conservatively with spontaneous resolution within 24 hours. This case illustrates that the rare complication of an intrapericardial thrombus after pericardiocentesis can be successfully managed conservatively with close monitoring in haemodynamically stable paediatric patients.

Sonuç Kartal, G, Koç Yekedüz, M, Köse, E, Eminoğlu, FT
Journal of pediatric endocrinology & metabolism : JPEM. 2024;(3):260-270
Abstract
OBJECTIVES Primary Coenzyme Q10 Deficiency-7 (OMIM 616276) results from bi-allelic pathogenic variants in the COQ4 gene. Common clinical findings include hypotonia, seizures, respiratory distress, and cardiomyopathy. In this report, we present two patients diagnosed with Primary Coenzyme Q10 Deficiency-7 along with a review of previously published cases, with the aim being to provide a better understanding of the clinical and laboratory manifestations of the disease. CASE PRESENTATION A 3-month-and-22-day-old male was admitted to our outpatient clinic due to poor feeding and restlessness. He was born following an uneventful pregnancy to a nonconsanguineous marriage. A physical examination revealed hypotonia, a dolichocephaly, periorbital edema, and long eyelashes. Blood tests revealed metabolic acidosis and elevated serum lactate levels, while the genetic analysis revealed a variant previously reported as pathogenic, c.437T>G (p.Phe146Cys), in the COQ4 gene. Genetic tests were also conducted on both mother and father, and it revealed heterozygous variant, 0.437T>G (p.Phe146Cys), in the COQ4 gene. As a result of these findings, the patient was diagnosed with neonatal encephalomyopathy-cardiomyopathy-respiratory distress syndrome (Primary Coenzyme Q10 Deficiency-7). A 1-year-old male was admitted to our clinic with complaints of hypotonia, seizures, and feeding difficulties. He was born following an uneventful pregnancy to a nonconsanguineous marriage. On his first day of life, he was admitted to the neonatal intensive care unit due to poor feeding and hypotonia. A physical examination revealed microcephaly, a high palate, poor feeding, weak crying, hypotonia, bilateral horizontal nystagmus, and inability to maintain eye contact. Laboratory findings were within normal limits, while a whole exome sequencing analysis revealed a homozygous variant previously reported as pathogenic, c.458C>T (p.A153V), in the COQ4 gene. The patient was diagnosed with Primary Coenzyme Q10 Deficiency-7. CONCLUSIONS Primary Coenzyme Q10 Deficiency-7 should be considered in the differential diagnosis of infants presenting with neurological and dysmorphic manifestations.

Abstract
BACKGROUND Tinnitus, which is often associated with reduced quality of life, depression, and sleep disturbances, lacks a definitive treatment targeting its pathophysiological mechanism. Inflammatory markers like TNF-α have been linked to tinnitus, thereby underlining the necessity for innovative therapies. This case study investigates the potential benefits of a multi-approach rehabilitation intervention involving whole-body cryostimulation (WBC) for a 47-year-old male suffering from chronic neurophysiologic tinnitus, who had underwent various unsuccessful treatments from 2005. METHODS the patient underwent a personalized, multidisciplinary rehabilitation intervention covering diet, pharmacotherapy, physiotherapy and physical activity classes tailored to the patient's needs and capacities, repetitive transcranial magnetic stimulation (rTMS), and whole-body cryostimulation (WBC). RESULTS The adjunctive WBC intervention resulted in a significant progressive improvement in tinnitus severity (tinnitus handicap inventory Δ% = -46.3%, VAS tinnitus score Δ% = -40%). Additional positive outcomes were noted in sleep quality (PSQI Δ% = -41.67%), emotional wellbeing (BDI Δ% = -41.2%), and quality of life (SF-36, WHO-5 Δ% = +16.5). CONCLUSIONS This study supports the existing literature suggesting the potential of WBC as an adjunct in a multi-approach intervention in ameliorating tinnitus severity and tinnitus-associated disorders. However, randomized controlled trials in larger populations, which specifically consider WBC's effects on tinnitus, are necessary to confirm these findings and to explore the mechanisms that underlie the observed improvements.

Clinico-Microbiological Correlation in Salmonella Endophthalmitis: Case Series and Review of Literature.
Mitra, S, Meshram, B, Jalali, S, Basu, S
Seminars in ophthalmology. 2024;(4):294-298
Abstract
PURPOSE To report two rare cases of Salmonella endogenous endophthalmitis in an immunocompromised premature baby and an immunocompetent adult and do a brief literature review of related cases. Diagnosis in both cases was confirmed only after the pathogen grew from ocular samples, in the absence of clear signs of enteric fever. METHODS Retrospective analysis of medical and microbiology records. RESULTS Both of our cases of Salmonella endophthalmitis had poor visual outcome, despite timely and aggressive management and irrespective of immune status of the patient. Salmonella infection being a rare cause of endophthalmitis was not initially suspected as the adult had minimal systemic symptoms 2 weeks before presentation, while the preterm baby was still on milk feeds. These were just two microbiologically confirmed cases of Salmonella endophthalmitis at our institute over the past 10 years, though enteric fever due to Salmonella species is endemic in Asian countries. CONCLUSIONS Salmonella endophthalmitis, though rare, leads to poor visual outcomes despite early recognition and aggressive management and may be confused with other infections or non-infectious entities such as necrotizing retinoblastoma in babies, in the absence of clear systemic signs of the disease.
