Fungal sinusitis is relatively rare, but it has become more common in recent years. When fungal sinusitis invades the orbit, it can cause proptosis, chemosis, ophthalmoplegia, retroorbital pain, and vision impairment. We present a case of an extensive orbital floor defect due to invasive fungal sinusitis. A 62-year-old man with hypertension and a history of lung adenocarcinoma, presented with right-side facial pain and swelling. On admission, the serum glucose level was 347 mg/dL, and hemoglobin A1c was 11.4%. A computed tomography scan and a Waters’ view X-ray showed right maxillary sinusitis with an orbital floor defect. On hospital day 3, functional endoscopic sinus surgery was performed by the otorhinolaryngology team, and an aspergilloma in necrotic inflammatory exudate obtained during exploration. On hospital day 7, orbital floor reconstruction with a Medpor Titan surgical implant was done. In principle, the management of invasive sino- orbital fungal infection often begins with surgical debridement and local irrigation with an antifungal agent. Exceptionally, in this case, debridement and immediate orbital floor reconstruction were performed to prevent enophthalmos caused by the extensive orbital floor defect. The patient underwent orbital floor reconstruction and received intravenous and oral voriconazole. Despite orbital invasion, there were no ophthalmic symptoms or sequelae.

Objective: The purpose of this study was to evaluate the relationship between rotational disk displacement (DD) of the temporomandibular joint (TMJ) and the dentoskeletal morphology. Methods: Women aged > 17 years were included in this study. Each subject had a primary complaint of malocclusion and underwent routine cephalometric examinations. They were divided into five groups according to the findings on sagittal and coronal magnetic resonance images of their TMJs: bilateral normal disk position, bilateral anterior DD with reduction (ADDR), bilateral rotational DD with reduction (RDDR), bilateral anterior DD without reduction (ADDNR), and bilateral rotational DD without reduction (RDDNR). Twenty-three cephalometric variables were analyzed, and the Kruskal–Wallis test was used to evaluate differences in the dentoskeletal morphology among the five groups. Results: Patients with TMJ DD exhibited a hyperdivergent pattern with a retrognathic mandible, unlike those with a normal disk position. These specific skeletal characteristics were more severe in patients exhibiting DD without reduction than in those with reduction, regardless of the presence of rotational DD. Rotational DD significantly influenced horizontal and vertical skeletal patterns only in the stage of DD with reduction, and the mandible exhibited a more backward position and rotation in patients with RDDR than in those with ADDR. However, there were no significant dentoskeletal differences between ADDNR and RDDNR. Conclusions The results of this study suggest that rotational DD of TMJ plays an important role in the dentoskeletal morphology, particularly in patients showing DD with reduction.

Objective: This aim examined the outcomes of resuscitation and the clinical characteristics of patients with pre-hospitaltraumatic cardiac arrests (TCA). Methods: The charts of patients with pre-hospital TCA who visited the various emergency department (ED) in Gangwondofrom January 2013 to December 2017 were reviewed retrospectively. Results: TCA patients comprised 0.3% of patients transferred by 119. A total of 367 patients were enrolled in the study.Traffic accidents were the leading cause of the arrest. The initial field and ED rhythm were mostly asystole (field, 79.6%;ED, 82.3%). It took 11.24±9.95 minutes from the call to the field. From the field to ED, it took 22.87±15.37 minutes. Thetotal CPR time before ED arrival was 21.62±15.29 minutes. The causes of TCA were brain injury (35.7%), hypovolemicshock (29.2%), and severe lung injury (16.3%). Seventy TCA patients experienced at least one return of spontaneous circulation(ROSC). Twenty-six patients (7.14%) were admitted to the ward, and their average injury severity score was38.96. Eight patients expired before 12 hours after transient ROSC. Four more patients expired before 24 hours. Fourpatients were discharged alive among patients who lived for more than 24 hours. Conclusion In this study, 1.5% of patients were discharged alive. The possibility of ROSC was higher as the time to ED,and the cardiopulmonary resuscitation time of 119 was shorter. Pulseless electrical activity rather than asystole tends topromote ROSC. The survival rate increased when ROSC occurred before arriving at the ED.

BACKGROUND: The objective of this study was to compare the impact of citrate dialysate (CD) and standard acetate dialysate (AD) in hemodialysis by central delivery system (CDS) on heparin demand, and clinical parameters. METHODS: We retrospectively evaluated 75 patients on maintenance hemodialysis with CDS. Patients underwent hemodialysis with AD over a six-month period (AD period), followed by another six-month period using CD (CD period). Various parameters including mean heparin dosage, high sensitivity C-reactive protein (hsCRP), calcium-phosphate product (CaxP), intact parathyroid hormone (iPTH), and urea reduction ratio (URR) were collated at the end of each period. RESULTS: Patients were 60.5 ± 14.7 years old, of whom 62.7% were male. Patients required less heparin when receiving CD (AD period: 1,129 ± 1,033 IU/session vs. CD period: 787 ± 755 IU/session, P < 0.001). After the CD period (Δ(CD)), pre-dialysis total CO₂ increased to 1.21 ± 2.80 mmol/L, compared to −2.44 ± 2.96 mmol/L (P < 0.001) after the AD period (Δ(AD)). After the CD period, concentrations of iPTH (Δ(AD): 73.04 ± 216.34 pg/mL vs. Δ(CD): −106.66 ± 251.79 pg/mL, P < 0.001) and CaxP (Δ(AD): 4.32 ± 16.63 mg²/dL² vs. Δ(CD): −4.67 ± 15.27 mg²/dL², P = 0.015) decreased. While hsCRP levels decreased after the CD period (Δ(AD): 0.07 ± 4.09 mg/L vs. Δ(CD): −0.75 ± 4.56 mg/L, P = 0.705), the change was statistically insignificant. URR remained above clinical guideline of 65% after both periods (Δ(AD): 72.33 ± 6.92% vs. Δ(CD) period: 69.20 ± 4.49%, P = 0.046). CONCLUSION: Our study confirmed that the use of CD in CDS required lower heparin doses compared to the use of AD. The use of CD also provided a more stable acid-base status.

Secretory carcinoma of the breast is an extremely rare, clinically and histologically distinct variant of invasive ductal carcinoma, with an indolent growth pattern and a more favorable prognosis than that of typical ductal carcinoma. Few studies have described its imaging features. Herein, we report on a secretory breast carcinoma with findings from various imaging modalities, especially including the MRI findings, which appears a well-defined complex cystic mass. Awareness of its imaging features using various modalities will be helpful for the differential diagnosis.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a potential cause of hyponatremia of the central nervous system (CNS). Although SIADH has been reported to be associated with many other central nervous disorders, its association with neuromyelitis optica (NMO) or NMO spectrum disorders are rare. NMO is a demyelinating disorder characterized by optic neuritis and transverse myelitis. Aquaporin-4 (AQP4), which is the target antigen for a NMO autoantibody, is the predominant CNS water channel. However, some NMO patients show seronegative AQP4 antibody results. The spectrum of NMO has been changed, and new findings about the disease have been reported. Here, we report a case of seronegative NMO spectrum disorder associated with SIADH.

Primary Sjögren's syndrome (pSS) is characterized by lymphocytic infiltration of the exocrine glands resulting in decreased saliva and tear production. It uncommonly involves the kidneys in various forms, including tubulointerstitial nephritis, renal tubular acidosis, Fanconi syndrome, and rarely glomerulonephritis. Its clinical symptoms include muscle weakness, periodic paralysis, and bone pain due to metabolic acidosis and electrolyte imbalance. Herein, we describe the cases of two women with pSS whose presenting symptoms involve the kidneys. They had hypokalemia and normal anion gap metabolic acidosis due to distal renal tubular acidosis and positive anti-SS-A and anti-SS-B autoantibodies. Since one of them experienced femoral fracture due to osteomalacia secondary to renal tubular acidosis, an earlier diagnosis of pSS is important in preventing serious complications.

BACKGROUND: Immunoglobulin E (IgE) has traditionally been associated with anaphylaxis and atopic disease. Previous studies reported that serum IgE levels are elevated in nephrotic syndrome and suggested IgE levels as a prognostic indicator in glomerular diseases. The aim of this study was to explore the association between serum IgE levels and renal outcome in patients with immunoglobulin A nephropathy (IgAN). METHODS: We included 117 patients with biopsy-proven IgAN. Renal progression was defined if a patient meets one of these criteria: (1) a negative value of delta estimated glomerular filtration rate (mL/min/1.73 m²/mo) or (2) a rise in serum creatinine to an absolute level of ≥ 1.3 mg/dL (male) or 1.2 mg/dL (female). We defined delta changes in serum creatinine, estimated glomerular filtration rate, and proteinuria as a difference of values during the follow-up period. RESULTS: A total of 117 patients with IgAN were included. The serum IgE level was significantly high in the renal progressive group compared with the nonprogressive group. Sex and history of gross hematuria were significantly different between the high-IgE group and the low-IgE group. Regression analysis showed that a male sex, initial proteinuria, and change of proteinuria were significantly associated with serum IgE levels. CONCLUSION: The serum IgE level is potentially associated with disease progression and pathogenesis of IgAN.

BACKGROUND: In many countries, nephrologists follow clinical practice guidelines for mineral bone disorders to control secondary hyperparathyroidism (SHPT) associated with abnormal serum calcium (Ca) and phosphorus (P) levels in patients undergoing maintenance hemodialysis (MHD). The Kidney Disease Outcomes Quality Initiative (KDOQI) Guidelines have long been used in Korea, and this study was undertaken to investigate the current status of serum Ca and P control in MHD patients. METHODS: Data were collected from a total of 1,018 patients undergoing MHD without intercurrent illness, in 17 hemodialysis centers throughout the country. Serum levels of Ca, P, and intact parathyroid hormone (iPTH) were measured over 1 year, and the average values were retrospectively analyzed. RESULTS: Serum levels of Ca, P, and the CaxP product were 9.1+/-0.7mg/dL, 5.3+/-1.4mg/dL, and 48.0+/-13.6mg2/dL2, respectively. However, the percentages of patients with Ca, P, and Ca x P product levels within the KDOQI guideline ranges were 58.7%, 51.0%, and 70.7%, respectively. Of the 1,018 patients, 270 (26.5%) had iPTH >300pg/mL (uncontrolled SHPT), whereas 435 patients (42.7%) showed iPTH <150pg/mL. Patients with uncontrolled SHPT had significantly higher values of serum Ca, P, and CaxP product than those with iPTH < or =300pg/mL. CONCLUSION: Despite the current clinical practice guidelines, SHPT seems to be inadequately controlled in many MHD patients. Uncontrolled SHPT was associated with higher levels of serum Ca, P, and Ca x P product, suggestive of the importance of SHPT management.
