The Yearly Periodicity of Operative Upper Extremity Trauma: A Retrospective Study of "Trauma Season".

Background: Upper extremity (UE) trauma requiring operative care increases during the summer and fall months, which the authors colloquially refer to as "trauma season."

Methods: CPT databases were queried for codes related to acute UE trauma at a single level-1 trauma center. Monthly CPT code volume was tabulated for 120 consecutive months and average monthly volume was calculated.

IgA nephropathy diagnosed as a result of acute exacerbation due to G-CSF administration.

Granulocyte colony-stimulating factor (G-CSF) is commonly used to stimulate bone marrow production. G-CSF is usually safe but sometimes causes serious adverse effects and, in rare cases, exacerbates glomerulonephritis. We report a case of immunoglobulin A (IgA) nephropathy that was aggravated by G-CSF.

A case of juvenile-onset fibrillary glomerulonephritis diagnosed by mass spectrometry and immunohistochemistry of DNAJB9.

Fibrillary glomerulonephritis (FGN) is a rare glomerular disease. FGN is characterized by the deposition of randomly arranged, nonbranching microfibrils in the mesangium and glomerular basement membrane. The discovery of DNAJ homolog subfamily B member 9 (DNAJB9) in 2017 was a breakthrough, and DNAJB9 has been proven to be extremely useful for the definitive diagnosis of FGN.

Square-root Palatoplasty: Comparing a Novel Modified-Furlow Double-opposing Z-palatoplasty Technique to Traditional Straight-line Repair.

Unlabelled: The purpose of this study was to introduce a modification of the Furlow double-opposing Z-plasty (DOZ)-the square-root palatoplasty (SRP)-and critically evaluate outcomes compared to children who underwent straight-line repair (SLR).

Methods: A retrospective review was performed of all nonsyndromic children undergoing primary cleft palate closure either by SRP or SLR at our institution between 2009 and 2017. Outcomes of interest included rates/location of oronasal fistula, secondary surgery, speech delay/deficits, resonance, nasal air emission (NAE), articulation errors, and velopharyngeal function.

No Longer a Pain in the Neck: Use of Operating Microscope for Palatoplasty.

For craniofacial surgeons, cleft palate repair is an intricate and difficult operation positionally. Historically, use of loupe magnification and a headlight can cause significant strain to the surgeon's neck and, at times, subpar optics for both the operator and the assistant. The use of an operating microscope was first advocated by Sommerlad in 2003.

Unique pathological changes in the pancreas of fulminant type 1 diabetes.

Distinct features of the pancreas of fulminant type 1 diabetes (FT1DM) include (1) enterovirus infection of the islets and exocrine acinar tissue. (2) Activated innate immune responses: MDA5 and RIG-I expression and TLR4 and TLR9 expression in the islets of FT1DM. (3) Combined activation of the STAT/JNK and NFkB pathways, resulting in Type I interferon (IFN) and proinflammatory cytokine (i.

Use of Postmastectomy Radiation in Patients Treated for Invasive Breast Cancer with Mastectomy and Immediate Reconstruction.

Immediate reconstruction after mastectomy helps women manage the psychological impact of deforming surgery. Postmastectomy radiation therapy (PMRT) can negatively impact the aesthetic result after breast reconstruction. We performed this study to achieve a better understanding of how PMRT is used after reconstruction in our institution.

Diffusion-weighted magnetic resonance imaging in the pancreas of fulminant type 1 diabetes.

Abrupt disease onset and severe metabolic disorders are main characteristics of fulminant type 1 diabetes. Diffusion-weighted magnetic resonance imaging (DWI) is an imaging technique that reflects restricted diffusion in organs and can detect mononuclear cell infiltration into the pancreas at the onset of the disease. Fourteen patients with fulminant type 1 diabetes who underwent abdominal magnetic resonance imaging were recruited for the measurement of apparent diffusion coefficient (ADC) values of the pancreas that were compared with those of 21 non-diabetic controls.

Genome-Wide Association Study Confirming a Strong Effect of HLA and Identifying Variants in on Chromosome 12q13.13 Associated With Susceptibility to Fulminant Type 1 Diabetes.

The first genome-wide association study of fulminant type 1 diabetes was performed in Japanese individuals. As previously reported using a candidate gene approach, a strong association was observed with multiple single nucleotide polymorphisms (SNPs) in the HLA region, and the strongest association was observed with rs9268853 in the class II DR region ( = 1.56 × 10, odds ratio [OR] 3.

Possible Long-Term Efficacy of Sitagliptin, a Dipeptidyl Peptidase-4 Inhibitor, for Slowly Progressive Type 1 Diabetes (SPIDDM) in the Stage of Non-Insulin-Dependency: An Open-Label Randomized Controlled Pilot Trial (SPAN-S).

Introduction: We tested the hypothesis that dipeptidyl peptidase-4 (DPP-4) inhibitors are effective in preserving the β-cell function for long-term periods in patients with slowly progressive type 1 diabetes (SPIDDM) or latent autoimmune diabetes in adults (LADA).

Methods: In the present open-label, randomized, controlled trial, 14 non-insulin-requiring diabetic patients with glutamic acid decarboxylase autoantibodies (GADAb) were randomly assigned to receive either sitagliptin (S group) or pioglitazone (P group). As a historical control, the Tokyo Study, in which non-insulin-dependent patients with SPIDDM were assigned to receive treatment by either insulin or sulfonylurea (SU), was used.

Association Between Compliance with Triage Directions from an Organized State Trauma System and Trauma Outcomes.

Background: The Louisiana Emergency Response Network (LERN), a statewide trauma system, has a single communication center with real-time data on hospital capacity across the state. With these data, scene information, and a standardized triage protocol, prehospital providers are directed to the most appropriate hospital. The purpose of our study was to compare outcomes between those patients who complied with the LERN communication center direction and those who did not.

Insufficient Humidification of Respiratory Gases in Patients Who Are Undergoing Therapeutic Hypothermia at a Paediatric and Adult Intensive Care Unit.

For cooled newborn infants, humidifier settings for normothermic condition provide excessive gas humidity because absolute humidity at saturation is temperature-dependent. To assess humidification of respiratory gases in patients who underwent moderate therapeutic hypothermia at a paediatric/adult intensive care unit, 6 patients were studied over 9 times. Three humidifier settings, 37-default (chamber-outlet, 37°C; Y-piece, 40°C), 33.

Clinical features of cases of seroconversion of anti-glutamic acid decarboxylase antibody during the clinical course of type 2 diabetes: a nationwide survey in Japan.

The pathogenesis of type 1 diabetes is different from that of type 2 diabetes, and anti-glutamic acid decarboxylase antibody (GADA) helps to diagnose autoimmune type 1 diabetes. Some studies reported that GADA seroconversion occurs during the clinical course of type 2 diabetes, leading to development of "type 1 on type 2 diabetes". To clarify the clinical characteristics and triggers of GADA seroconversion, we performed a nationwide questionnaire survey for clinical cases identified by literature search, and obtained information on 38 cases (24 with insulin therapy and 14 without it).

The Impact of Chemotherapy on Complications Associated with Mastectomy and Immediate Autologous Tissue Reconstruction.

We performed this study to evaluate the impact of chemotherapy on the outcomes associated with immediate autologous tissue reconstruction (IATR) in the treatment of breast cancer. Patients were divided into two groups: Group 1 received chemotherapy before surgery and Group 2 did not receive chemotherapy. Records were reviewed to identify demographics, comorbidities, histology, and wound healing complications.

Clinical and Genetic Characteristics of Non-Insulin-Requiring Glutamic Acid Decarboxylase (GAD) Autoantibody-Positive Diabetes: A Nationwide Survey in Japan.

Aims: Glutamic acid decarboxylase autoantibodies (GADAb) differentiate slowly progressive insulin-dependent (type 1) diabetes mellitus (SPIDDM) from phenotypic type 2 diabetes, but many GADAb-positive patients with diabetes do not progress to insulin-requiring diabetes. To characterize GADAb-positive patients with adult-onset diabetes who do not require insulin therapy for >5 years (NIR-SPIDDM), we conducted a nationwide cross-sectional survey in Japan.

Methods: We collected 82 GADAb-positive patients who did not require insulin therapy for >5 years (NIR-SPIDDM) and compared them with 63 patients with insulin-requiring SPIDDM (IR-SPIDDM).

Use of Normothermic Default Humidifier Settings Causes Excessive Humidification of Respiratory Gases During Therapeutic Hypothermia.

Adult patients frequently suffer from serious respiratory complications during therapeutic hypothermia. During therapeutic hypothermia, respiratory gases are humidified close to saturated vapor at 37°C (44 mg/L) despite that saturated vapor reduces considerably depending on temperature reduction. Condensation may cause serious adverse events, such as bronchial edema, mucosal dysfunction, and ventilator-associated pneumonia during cooling.

Rapid Normalization of High Glutamic Acid Decarboxylase Autoantibody Titers and Preserved Endogenous Insulin Secretion in a Patient with Diabetes Mellitus: A Case Report and Literature Review.

A 59-year-old Japanese woman developed diabetes mellitus without ketoacidosis in the presence of glutamic acid decarboxylase autoantibody (GADA) (24.7 U/mL). After the amelioration of her hyperglycemia, the patient had a relatively preserved serum C-peptide level.

Intracystic Biopsy and Diagnosis of Intraductal Papillary Mucinous Neoplasm via SpyGlass Pancreatoscopy.

Background: Intraductal papillary mucinous neoplasm (IPMN) of the pancreas carries a risk of malignancy ranging from 15%-60%, depending on certain high-risk features. Diagnostic efforts often include radiographic imaging with computed tomography, magnetic resonance imaging, magnetic resonance cholangiopancreatography, and endoscopic ultrasound. Once IPMN has been diagnosed, the proposed indications for cyst resection are based primarily on size, main duct involvement, symptoms, and the presence of mural nodules.

Risk factors for sudden death and cardiac arrest at the onset of fulminant type 1 diabetes mellitus.

Aims: The onset of fulminant type 1 diabetes mellitus is sometimes accompanied by sudden death or cardiac arrest. The aim of this study was to determine the risk factors for the development of these conditions at the onset of fulminant type 1 diabetes mellitus.

Methods: We conducted a search of the literature on fulminant type 1 diabetes and sudden death or cardiac arrest published up to 2012 in PubMed and Ichushi (a Japanese article database), and a questionnaire survey was administered to the authors of the articles and to diabetes specialists affiliated to the Japan Diabetes Society.

Predictive value of titer of GAD antibodies for further progression of beta cell dysfunction in slowly progressive insulin-dependent (type 1) diabetes (SPIDDM).

Aims: Whether the titer of glutamic acid decarboxylase antibodies (GADAs), especially a low titer, is a marker of progression of beta cell dysfunction in patients with slowly progressive insulin-dependent (type 1) diabetes (SPIDDM) is unclear.

Materials And Methods: Patients were subdivided as follows: patients with high GADA titers [≥10 U/ml (≥180 WHO U/ml): high GADA] (group 1,  = 37); those with low GADA titers [<10 U/ml (<180 WHO U/ml): low GADA] (group 2,  = 33); those without GADA and with islet cell antibodies (ICA) (group 3,  = 8); those without both GADA and ICA and with insulinoma-associated antigen 2 antibodies (IA-2A) (group 4,  = 6). We also allocated 198 type 2 diabetic patients without any GADA, ICA or IA-2A as group 5.

Measurement of soluble C-type lectin-like receptor 2 in human plasma.

Detection of platelet activation in vivo is useful to identify patients at risk of thrombotic diseases. Platelet factor 4 (PF4) and β-thromboglobulin (β-TG) are used for this purpose; however, they are easily released upon the minimal platelet activation that occurs during sampling. Soluble forms of several platelet membrane proteins are released upon platelet activation; however, the soluble form of C-type lectin-like receptor 2 (sCLEC-2) has not yet been fully investigated.

Distinct cell clusters touching islet cells induce islet cell replication in association with over-expression of Regenerating Gene (REG) protein in fulminant type 1 diabetes.

Background: Pancreatic islet endocrine cell-supporting architectures, including islet encapsulating basement membranes (BMs), extracellular matrix (ECM), and possible cell clusters, are unclear.

Procedures: The architectures around islet cell clusters, including BMs, ECM, and pancreatic acinar-like cell clusters, were studied in the non-diabetic state and in the inflamed milieu of fulminant type 1 diabetes in humans.

Result: Immunohistochemical and electron microscopy analyses demonstrated that human islet cell clusters and acinar-like cell clusters adhere directly to each other with desmosomal structures and coated-pit-like structures between the two cell clusters.

A low-frequency GLIS3 variant associated with resistance to Japanese type 1 diabetes.

The role of low-frequency variants in type 1 diabetes (T1D) susceptibility still remains to be clarified. In the present study, we analyzed low-frequency variants of the T1D candidate genes in Japanese. We first screened for protein-changing variants of 24 T1D candidate genes in 96 T1D patients and 96 control subjects, and then the association with T1D was tested in 706 T1D patients and 863 control subjects recruited from the collaborating institutions in Japan.
