With an increased use of the press-through package (PTP) tablet, there has also been an increase in mis-swallowing cases, especially in elderly patients. We report a rare case of PTP-induced small bowel perforation and fistula formation with adjacent small bowel in a healthy elderly patient, who experienced persistent abdominal pain of unknown cause. A 62-year-old healthy man was admitted to our hospital with left abdominal pain that started one month ago. Neither abdominal tenderness nor rebound tenderness was present on physical examination...

Superior mesenteric artery (SMA) syndrome is one of the rare causes of small bowel obstruction. It develops following a marked decrease in the angle between SMA and the abdominal aorta due to weight loss, anatomical anomalies, or following surgeries. Nutcracker syndrome in the left renal vein may also occur following a decrease in the aortomesenteric angle. Though SMA syndrome and renal nutcracker syndrome share the same pathogenesis, concurrent development has rarely been reported. Herein, we report a 23-year-old healthy male diagnosed with SMA syndrome and renal nutcracker syndrome due to severe weight reduction...

Ependymoma is the third most common pediatric primary brain tumor. Ependymomas are categorized according to their locations and genetic abnormalities, and these two parameters are important prognostic factors for patient outcome. For supratentorial (ST) ependymomas, RELA fusion-positive ependymomas show a more aggressive behavior than YAP1 fusion-positive ependymomas. Extracranial metastases of intra-axial neuroepithelial tumors are extremely rare. In this paper, we report a case of aggressive anaplastic ependymoma arising in the right frontoparietal lobe, which had genetically 1q25 gain, CDKN2A homozygous deletion, and L1CAM overexpression...

The Calcifying Odontogenic Cyst was first described as a distinct clinicopathologic entity by Gorlin and his colleagues in 1962. Gold (1963) chose a similar, but not identical term for the lesion, namely 'keratinizing and calcifying odontogenic cyst'. The calcifying cystic odontogenic tumor (CCOT) is a new designation of calcifying odontogenic cyst (COC) recommended by the 2005 classification of the World Health Organization (WHO). The calcifying odontogenic cyst is not a common lesion; the dentinogenic ghost cell tumor is even less common and should be considered rare...

Elbow flexor force steadiness (FS) depends on strength and decreases with age. Achilles tendon mechanics effect standing balance and isometric plantarflexion FS. This study investigated the influence of distal biceps brachii (BB) tendon mechanics and elbow flexor strength on age-related decline in FS. Nine young (23±2 years) and 9 old (77±5 years) males performed submaximal isometric elbow flexion tasks at low (2.5, 5, 10% maximal voluntary contraction (MVC)) and high (20, 40, 60, 80%MVC) forces in a neutral forearm position...

BACKGROUND: There is an extensive literature describing temperature-mortality associations in developed regions, but research from developing countries, and Africa in particular, is limited. METHODS: We conducted a time-series analysis using daily temperature data and a national dataset of all 8.8 million recorded deaths in South Africa between 1997 and 2013. Mortality and temperature data were linked at the district municipality level and relationships were estimated with a distributed lag non-linear model with 21 days of lag, and pooled in a multivariate meta-analysis...

REVIEW
Michio Wendell Painter
The aging peripheral nervous system (PNS) is prone to a number of disorders, including the development of neuropathies and increased regenerative failure. Although the basic mechanisms of the aging PNS are still rather murky, recent work has revealed that 'old' Schwann cells acquire a number of dysfunctions in mammals. This review will assess our current knowledge about aging Schwann cells while emphasizing where gaps exist. Indeed, as our understanding of how these peripheral glia contribute to the development, maintenance and regeneration of the PNS becomes increasingly refined, we should also turn our attention to questions of escalating importance in our rapidly greying society: how do Schwann cells change with aging, how might these changes contribute to dysfunction and disease, and what, if anything, might this tell us about the aging central nervous system?...

Context: Cushing's syndrome is rarely caused by the secretion of cortisol from the ovarian tumors. It is important to determine whether the ovarian tumor is capable of secreting cortisol or not in clinical decision making. Selective ovarian and adrenal venous sampling has not been reported previously in the localization of ACTH-independent ectopic Cushing's syndrome. Case description: Herein, we presented a case of 40-year-old Chinese woman who has been manifested with weight gain, hirsutism, hypertension and menstrual disorder over a period of 6 months...

Objective: Lutein (L) and zeaxanthin (Z) are phytonutrients that accumulate in human brain tissue and positively impact cognition. Given their antioxidant and anti-inflammatory properties and their role in stabilizing cell membranes, L&Z may relate to measures of white matter integrity (WMI). Method: The current study tested the relation of retinal (macular pigment optical density/MPOD) and blood serum concentrations of L&Z to WMI in community-dwelling older adults (n = 54) using diffusion tensor imaging (DTI)...

Background: Old age at prostate cancer diagnosis has been associated with poor prognosis in several studies. We aimed to investigate the association between age at diagnosis and prognosis, and if it is independent of tumor characteristics, primary treatment, year of diagnosis, mode of detection and comorbidity. Patients and methods: We conducted a nation-wide cohort study including 121,392 Swedish men aged 55-95 years in Prostate Cancer data Base Sweden (PCBaSe) 3...

BACKGROUND AND AIMS: Left ventricular hypertrophy (LVH) in hypertension is associated with a greater risk of sustained supraventricular/atrial arrhythmias. Dronedarone is an antiarrhythmic agent that was recently approved for the treatment of atrial fibrillation. However, its effect on early regression of LVH has not been reported. We tested the hypothesis that short-term administration of dronedarone induces early regression of LVH in spontaneously hypertensive rats (SHRs). METHODS: Ten-month-old male SHRs were randomly assigned to an intervention group (SHR-D), where animals received dronedarone treatment (100 mg/kg) for a period of 14 days, or to a control group (SHR) where rats were given vehicle...

Thomas Schmickl, Istvan Karsai
We propose a new regulation mechanism based on the idea of the "common stomach" to explain several aspects of the resilience and homeostatic regulation of honeybee colonies. This mechanism exploits shared pools of substances (pollen, nectar, workers, brood) that modulate recruitment, abandonment and allocation patterns at the colony-level and enable bees to perform several survival strategies to cope with difficult circumstances: Lack of proteins leads to reduced feeding of young brood, to early capping of old brood and to regaining of already spent proteins through brood cannibalism...

INTRODUCTION: Although the introduction of BRAF and MEK inhibitors has greatly enhanced treatment possibilities in advanced BRAFV600-mutated melanoma, class-related toxicities are rather frequent and often involve the eye. Ophthalmologic side effects most commonly include central/diffuse serous retinopathy and retinal vein occlusion. Affection of the optic nerve head however has not been described clinically. CASE REPORT: A 29-year-old man presented in our eye clinic with bilateral blurred vision...

We report a case of a 25-year-old woman with unilateral Coats'-like disease. Her brother was previously diagnosed with an autosomal dominant form of dyskeratosis congenita. Genetic testing was performed by screening the TERC gene for mutations and identified heterozygosity for the n.68_124del mutation. Our case demonstrates that the exudative retinopathy seen in Coats'-like disease can be caused by mutations in a telomere-capping gene TERC as a part of the dyskeratosis congenita spectrum without other systemic involvement...

Eggplant allergy is rare and most of the previously described reactions were mild. In this case report, we present an interesting case of a 27-year-old male who experienced symptoms of anaphylaxis (shortness of breath, and swelling of the face, lips and tongue, which was followed by hypotension, tachycardia of 140/min and a sudden loss of consciousness) several minutes after eating a dish containing backed eggplant. Previously, the patient had experienced symptoms of allergy after eating different types of food, such as salad and chicken in spices...

Simultaneous pancreas/kidney (SPK) transplantation is an important treatment option for patients with type 1 diabetes (T1D) and end stage renal disease (ESRD). Due to complications, in up to 10% of cases allograft pancreatectomy is necessary shortly after transplantation. Usually the donor pancreas is discarded. Here we report on a novel procedure to rescue endocrine tissue after allograft pancreatectomy. A 39-year-old woman with T1D and ESRD who had received an SPK transplantation required emergency allograft pancreatectomy due to bleeding at the vascular anastomosis...

The cerebral blood flow (CBF) is a potential biomarker for neurological disease. However, the arterial transit time (ATT) of the labeled blood is known to potentially affect CBF quantification. Furthermore, ATT could be an interesting biomarker in itself, as it may reflect underlying macro- and microvascular pathologies. Currently, no optimized magnetic resonance imaging (MRI) sequence exists to measure ATT in mice. Recently, time-encoded labeling schemes have been implemented in rats and humans, enabling ATT mapping with higher signal-to-noise ratio (SNR) and shorter scan time than multi-delay arterial spin labeling (ASL)...
