RESUMEN
Orbital floor fractures are commonly encountered, but the dislocation of the eyeball into the maxillary sinus is relatively rare. When it does occur, globe dislocation can have serious consequences, including vision loss, enucleation, and orbito-ocular deformity. Immediate surgical intervention is typically attempted when possible. However, severe comorbidities and poor general health can delay necessary surgery. In this report, we present the surgical outcomes of a 70-year-old woman who received delayed treatment for traumatic eyeball dislocation into the maxillary sinus due to a subarachnoid hemorrhage and hemopneumothorax. Additionally, we propose a treatment algorithm based on our clinical experience and a review of the literature.
RESUMEN
Purpose@#The ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) is considered a predictive marker of preeclampsia. However, the relationship between the sFlt-1/PlGF ratio and perinatal and neonatal outcomes remains unknown. This study aimed to determine the associations of the sFlt-1/PlGF ratio with perinatal and neonatal outcomes in newborns born to mothers with preeclampsia. @*Methods@#This retrospective cohort study reviewed singleton neonates born to mothers with preeclampsia who underwent testing for the sFlt-1/PlGF ratio. We investigated the relationship between maternal sFlt-1/PlGF ratios and gestational age (GA), birth weight (Bwt), Bwt z-score, morbidities, and mortality of neonates born to mothers tested for the sFlt-1/PlGF ratio. Maternal sFlt-1/PlGF ratios examined within 30 days before delivery were used for analysis. Neonatal morbidities and mortality were investigated only in preterm infants born earlier than 32 weeks GA. @*Results@#A total of 225 neonates were included, of which 163 (72.4%) were preterm infants. GA (R=– 0.577, p<0.001), Bwt (R=–0.713, p<0.001), and Bwt z-score (R=–0.608, p<0.001) exhibited significant negative correlations with the sFlt-1/PlGF ratios. Among the 50 preterm infants born earlier than 32 weeks GA, neonatal morbidities were not significantly associated with the sFlt-1/PlGF ratio after adjusting for GA and Bwt. @*Conclusion@#In mothers with preeclampsia, a higher sFlt-1/PlGF ratio was associated with the delivery of newborns with lower GA and lower Bwt. However, this ratio was not associated with increased morbidity or mortality in premature infants born earlier than 32 weeks GA.
RESUMEN
Purpose@#Extremely preterm infants are prone to brain injury and underdevelopment. Intraventricular hemorrhage (IVH) is the most common cause of brain injury and a significant risk factor for neurodevelopmental delay in preterm infants. Severe IVH is known to have a poor outcome; however, the outcomes of low-grade IVH remain controversial. This study aimed to evaluate neurodevelopmental outcomes and brain segmental volumes of preterm infants with low-grade IVH. @*Methods@#This retrospective cohort study included 109 extremely preterm infants who underwent term equivalent age-magnetic resonance imaging and neurodevelopmental evaluation at a corrected age of 18 to 24 months. We compared infants with and without low-grade IVH. @*Results@#Among the 109 extremely preterm infants, 25 had low-grade IVH and 84 had no IVH. There were no significant differences in the neurodevelopmental outcomes between the low-grade and no IVH groups. In multivariate analysis, low-grade IVH was associated with a smaller medullary volume (adjusted odds ratio, 0.575; 95% confidence interval, 0.346 to 0.957; P=0.034). @*Conclusion@#We found no significant differences in the neurodevelopmental outcomes of extremely preterm infants at a corrected age of 18 to 24 months between those with low-grade IVH and those without IVH. Low-grade IVH was associated with a smaller medullary volume.
RESUMEN
This case report describes our treatment of a persistent periantral abscess in a 35-year-old woman. The abscess developed following a zygoma-reduction surgery, during which a preexisting fungal ball had not been addressed. Our comprehensive treatment approach included functional endoscopic sinus surgery, fungal ball removal, abscess drainage, and debridement. Two weeks postoperatively, the patient’s symptoms had resolved. A 6-month postoperative follow-up revealed no signs of recurrence or complications, and the patient reported satisfactory functional and aesthetic results. This case underscores the importance of thorough preoperative evaluations and raises awareness about the potential risks of untreated asymptomatic pathologies, which can potentially progress and lead to further complications.
RESUMEN
When it comes to the cold burn injury, rewarming with 37~39oC running water until the sensory restoration of the affected site is a well-established treatment modality. However, there have been few reports pertaining to liquid nitrogen induced cold burn injury followed by secondary rewarming burn. A 19-year-old male was exposed to liquid nitrogen of −196oC on his hands while only wearing a cotton glove. After rewarming treatment, tense and painful bullae occurred along the zone of injury. We applied a portable thermal camera to determine the treatment modality based on the state of the wound. With the aid of thermal camera monitoring, complete healing without burn scar contracture and limitation of motion was achieved.
RESUMEN
Background@#As the number of large-scale studies involving multiple organizations producing data has steadily increased, an integrated system for a common interoperable format is needed. In response to the coronavirus disease 2019 (COVID-19) pandemic, a number of global efforts are underway to develop vaccines and therapeutics. We are therefore observing an explosion in the proliferation of COVID-19 data, and interoperability is highly requested in multiple institutions participating simultaneously in COVID-19 pandemic research. @*Results@#In this study, a laboratory information management system (LIMS) approach has been adopted to systemically manage various COVID-19 non-clinical trial data, including mortality, clinical signs, body weight, body temperature, organ weights, viral titer (viral replication and viral RNA), and multiorgan histopathology, from multiple institutions based on a web interface. The main aim of the implemented system is to integrate, standardize, and organize data collected from laboratories in multiple institutes for COVID-19 non-clinical efficacy testings. Six animal biosafety level 3 institutions proved the feasibility of our system. Substantial benefits were shown by maximizing collaborative high-quality non-clinical research. @*Conclusions@#This LIMS platform can be used for future outbreaks, leading to accelerated medical product development through the systematic management of extensive data from non-clinical animal studies.
RESUMEN
Post-traumatic pseudoaneurysms of internal maxillary artery are rare, but may be life-threatening. When arterial damage leads to pseudoaneurysm formation, delayed intractable epistaxis can occur. We report our experience with the diagnosis and management of a ruptured internal maxillary arterial pseudoaneurysm that was discovered preoperatively in a patient with a zygomaticomaxillary complex (ZMC) fracture. He presented to the emergency room with epistaxis, which ceased shortly, and sinus hemorrhage was observed with a fracture of the posterior maxillary wall. The patient was scheduled for open reduction and internal fixation (ORIF) of the ZMC fracture. However, immediately before surgery, uncontrolled epistaxis of unknown origin was observed. Angiography indicated a pseudoaneurysm of the posterior superior alveolar artery. Selective endovascular embolization was performed, and hemostasis was achieved. After radiologic intervention, ORIF was successfully implemented without complications. Our case shows that in patients with a posterior maxillary wall fracture, there is a risk of uncontrolled bleeding in the perioperative period that could be caused by pseudoaneurysms, which should be considered even in the absence of typical symptoms.
RESUMEN
BACKGROUND: Localized scleroderma is characterized by a thickening of the skin from excessive collagen deposits. It is not a fatal disease, but quality of life can be adversely affected due to changes in skin appearance, joint contractures, and, rarely, serious deformities of the face and extremities. We present six cases of localized scleroderma in face from our surgical practice. METHODS: We reviewed six localized scleroderma cases that were initially treated with medication and then received follow-up surgery between April 2003 and February 2015. Six patients had facial lesions. These cases presented with linear dermal sclerosis on the forehead, oval subcutaneous and dermal depression in the cheek. RESULTS: En coup de sabre (n=4), and oval-shaped lesion of the face (n=2) were successfully treated. Surgical methods included resection with or without Z-plasty (n=3), fat graft (n=1), dermofat graft (n=1), and adipofascial free flap (n=1). Deformities of the affected parts were surgically corrected without reoccurrence. CONCLUSION: We retrospectively reviewed six cases of localized scleroderma that were successfully treated with surgery. And we propose an algorithm for selecting the best surgical approach for individual localized scleroderma cases. Although our cases were limited in number and long-term follow-up will be necessary, we suggest that surgical management should be considered as an option for treating scleroderma patients.

Congenital dermatofibrosarcoma protuberans (DFSP) is an extremely rare skin tumor that is commonly misdiagnosed, or is often diagnosed long after the initial presentation. Although many cases of DFSP are diagnosed in adulthood, there are some differences between adult DFSP and congenital DFSP. We report a case of congenital DFSP that was initially misdiagnosed as a simple vascular lesion. The delay in diagnosis led to the considerable growth of the lesion, such that a huge scar was left after the surgical treatment. The major differences between adult and congenital DFSP are discussed through a literature review. Clinicians should be aware of the characteristics of congenital DFSP, to reduce misdiagnosis and the delay of diagnosis from the initial presentation.
