Buried Superior Gluteal Artery Perforator Flap for Dead Space Coverage in the Sacral Area
Authors: Hong Seung Heon , Lee Kyeong-Tae
Published: February 2020

Partial sacrectomy is a common treatment for sacral sarcomas, which often results in a large defect and exposed rectal wall. The defect could be covered using a gluteus maximus (GM) advancement flap. However, seroma and wound dehiscence are often observed after GM advancement flap coverage, delaying the wound healing process. We present a case of buried superior gluteal artery perforator (SGAP) flap following GM muscle splitting. An 11-year-old male patient with epithelioid sarcoma in the sacrum underwent partial sacrectomy. The sacral defect size was 9×6 cm, and the GM muscle was intact. We designed a 7×4-cm elliptically-shaped SGAP flap skin paddle, after which perforator dissection was performed underneath the GM muscle. To minimize dead space, the GM muscle was split and the flap was de-epithelized and advanced to the posterior rectal wall. There were no wound complications during admission and the patient was discharged on postoperative day 16. No atrophy of the flap was found on postoperative magnetic resonance imaging, either. This case demonstrates that using a buried SGAP flap for covering dead space could be a good surgical method to cover wide sacral defects.

Published: February 2020

Here we report a successful treatment of animal bite wound involving the bone. We used an artificial dermal matrix to reconstruct the cortical defect and prevent adhesion of the tendinous structures. A 48-year-old woman visited the emergency department for a painful hand swelling due to a dog bite 2 months earlier. A physical examination revealed a firmly palpable lesion with swelling and tenderness on the dorsal aspect of her hand. Magnetic resonance imaging found lytic changes of the second metacarpal bone with cortical destruction and fluid collection. After debridement of the necrotic tissue, a cortical bone defect with inflammatory changes of the medulla was noted. Following several days of irrigation, an artificial dermal matrix was applied with skin flap coverage to restore the soft tissue and bone defect. Three months later, the patient showed good motion of her hand without any restrictions. We believe artificial dermal matrix can be a good treatment strategy for restoring bone defect and preventing tendon adhesion simultaneously.
Management of a High-Pressure Hot-Melt Adhesive Injection Injury
Authors: Hwang Sung Oh , Lee Soo Hyang
Published: February 2020

We present a case wherein hot-melt adhesive was injected into the finger using a high-pressure industrial glue gun. Unlike hot-melt adhesive contact burns, hot-melt adhesive is hard to remove when it is injected with a high-pressure glue gun, resulting in more severe injury. In our case, initial treatment was not adequate because the patient did not mention any unusual symptoms and the lesion itself did not show any unusual findings. Moreover, because of the absence of symptoms like pain, the patient attended an outpatient visit later than on the scheduled date. As a result, skin necrosis occurred. Surgery was performed to excise the necrotic tissue and remove hot-melt adhesive foreign bodies. One month after the surgery, the wound had completely healed without any complications. The aim of this case report is to highlight the damage associated with high-pressure hot-melt adhesive injection injury, which we believe is not sufficiently perceived by the naked eye. The characteristics of the injected material must be identified at first. And immediate surgical intervention is needed.

Authors: Kim Sang Hun , Nam Jeoung Hyun , Lee Man Ryul , Hwang Yongsung , Park Eun Soo
Published: February 2020

Background: Human-induced pluripotent stem cells (hiPSCs) complement the disadvantages of conventional embryonic stem cells and adult stem cells, and have the advantages of simplicity of production and pluripotency. Some recent studies have applied hiPSC in cell therapy.Methods: In this study, we examined the effect of cells similar to cord blood endothelial colony-forming cells (CB-ECFCs), differentiated from induced pluripotent stem cells, on angiogenesis and granulation tissue formation in the proliferative phase of wound healing. For cell transfer, we used methacrylated gelatin (GelMA)-co-poly(styrene sulfonate) (PSS) cryogel, which has better bioactivity than conventional hydrogels and excellent mechanical properties and swelling capacity. Two full-thickness skin defects, 0.8 cm in diameter, were made in each of our 12 experimental mice. Wound splinting models were used to prevent contraction of the wounds. In each of the experimental animals, 5×105 cells were applied with GelMA-co-PSS cryogel in one of the two wounds, while only a culture medium with cryogel was applied to the other wound.Results: Wound reduction rates in the experimental side showed increases compared to the control side in 3 days, but there was no statistical significance. The histological score was significantly increased (P<0.05), and histologic examination showed that angiogenesis and granulation formation were also increased in the experiment side.Conclusion: In conclusion, CB-ECFCs-like cells differentiated from hiPSCs were effective in promoting formation of angiogenesis and granulation tissue in a mouse wound healing model.

Published: February 2020

A 72-year-old male patient without underlying diseases presented with a flame burn injury on the fibula and talus of the ankle joint and soft tissue around the posterior lower leg. Necrotic tissue was removed with surgical debridement. Amputation was considered because loss of the bony structure on the ankle joint, including the fibula, hindered stability of the joint. We covered the soft tissue defect using an anterolateral thigh free flap and salvaged the limb using ankle and subtalar arthrodesis with tibiotalocalcaneal intramedullary nailing. The patient began self-ambulation 1 month after the surgery and did not develop any complications.

Published: February 2020

Necrotizing fasciitis is an uncommon but life-threatening infectious disease. In this report, we describe the cases of two patients who presented with an extremely rare necrotizing fasciitis of the scalp, originating from an odontogenic infection, and who were treated successfully with negative pressure wound therapy (NPWT). Both patients had diabetes mellitus and were admitted to the emergency department. Facial computed tomography revealed multifocal fluid collection, soft tissue swelling, and thickening from the perioral region to the scalp. Extensive incision, drainage, and debridement were performed. Taking into account the pain the patients were suffering and their general condition, NPWT was then applied instead of a povidone iodine-soaked dressing. With appropriate antibiotics, serial surgical debridement, and NPWT, the infection was controlled within a month from the first session of NPWT. For wound closure, one patient underwent primary closure and split thickness skin grafting with bone decortication, and the other patient underwent only primary closure. Although necrotizing fasciitis is associated with high morbidity and mortality, both patients’ general conditions improved, and their surgical wounds healed successfully. NPWT can be a safe, effective treatment for necrotizing fasciitis of the head and neck, and it can reduce both patients’ pain and physicians’ effort.

Authors: AKKAYA Mustafa , MENLİK Tayfun , SÖZEN Adnan
Published: February 2020

In this experimental study, the results of utilizing a nano-lubricant in place of compressor work fluid in a refrigeration system were examined. R134a refrigerant was utilized in the refrigeration system. Polyol ester (POE) was used as a base fluid and a nano-lubricant prepared from alumina oxide (Al2O3) nanoparticles was utilized. The experiments were carried out separately with nano-lubricants created by mixing Al2O3 nanoparticles in the ratios of 0.5% and 1.0% into POE oil. Additionally, 0.5% triton X100 (TX-100) surfactant was utilized in the nano-lubricant in order to ensure a homogeneous dispersion in the suspension. As a result of the experiments, the highest coefficient of performance (COP) value for the cooling system was obtained at the concentrations of 0.5% Al2O3 and 0.5% TX-100. In the experiments with pure POE oil, the COP value was increased by 18.27%. The power value drawn by the compressor was reduced by 12.53% at the concentrations of 0.5% Al2O3 and 0.5% TX-100.

Published: February 2020

The properties of biomass-based fuel and combustion tests showed that logging residues are promising renewable energy sources. The data used in this study were collected from four clear-felling areas in Järvselja Training and Experimental Forest Centre, Southeast Estonia in 2013–2014. Logging was carried out by harvesters in Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies [L.] Karst.), silver birch (Betula pendula Roth.) and black alder (Alnus glutinosa L. Gaertn.) dominated stands with a small admixture of other tree species according to the cut-to-length method and logging residues were placed in heaps. The aim of this research is to assess different characteristics of logging residues (quantity, moisture content, energetic potential, ash content and amount) in clear-felling areas. The highest load of slash was measured on the birch dominated study site, where the dry weight of the logging residues was 29 t ha−1. Only the branch fraction moisture content on the black alder dominated site (35.4%) was clearly different from respective values on other sites (21.6–25.4%). The highest calorific value of the residues was assessed with the residues from the birch dominated site, where in moist sample it was 365 GJ ha−1 and in dry matter 585 GJ ha−1. The heating value of the fresh residues is highest in coniferous trees. The highest ash content in branch segments was registered for the black alder dominated site. Järvselja data indicate higher quality in conifer dominated sites, yet a higher load of logging residues in broadleaf dominated stands.

Published: February 2020

This study aims to contribute to a better estimation of the density of fractures likely to favour the drainage of surface water in the High Ziz River (HZR) basin. The method adopted consists of the use of different airborne image processing techniques (filtering, enhancement and slope analysis) which allow a good discrimination of image discontinuities (lineaments) that can then be used for producing lineament maps. The influence of these lineaments on the underground flow is then studied. Indeed, it was possible to extract the lineament network, following the exploitation of remote sensing and an objectively completed analog analysis using the PCI Geomatica LINE module and its directional filters (Sobel directional filters by the ACP method), and to extract the hydrographic network of the HZR basin, using the ArcHydro tool. After superimposing these data, their thematic maps (of the lineament and hydrographic network) were developed. In addition, this comparison of the two hydrographic networks and lineament maps showed us very varied flow directions influenced by geological structures, particularly fracturing. The topography of the region also has a secondary impact on flows through the presence of slopes generally oriented towards the SE of the basin. The correlation of the results with the different directions of the orders of the hydrographic network allowed us to identify the potential effects of lineaments on the orientations of surface water circulation. In addition to these results, the realization of the Rose diagram indicated that the dominant trend in lineaments is N90–45N° (NE–SW).
Relief as an important factor in determining priority landscapes: a case study on Polish landscape parks
Authors: Wałdykowski Piotr , Adamczyk Joanna , Cieszewska Agata
Published: February 2020

The practical problems of implementing the Regulation on Landscape Audits (European Landscape Convention, ELC) in Poland are discussed through the topic of landscape relief, on an example of landscape classification of three of Poland’s landscape parks. In the existing landscape typologies, various criteria are proposed, in which relief is usually considered to be one of the leading components. The study was carried out for the purposes of the Landscape Parks Conservation Plans, based on a comparison of the method under the Principles of Landscape Audits and the authors’ method. The results indicate that the landscape types set out in the regulation insuficiently take relief into account, leading to omitting the local specific nature of the terrain. The essential attributes of the terrain in the analysed parks are the morphometry of relief and its genesis. Relief helps to determine the landscape types that are more related to the terrain.

Authors: Bushljetik Irena Rambabova , Trajceska Lada , Pusevski Vladimir , Spasovski Goce
Published: February 2020

Introduction: Asymptomatic hypoglycaemia has been reported in both diabetic and non-diabetic patients on haemodialysis. Uremic symptoms as inadequate appetite, nausea and vomiting worsen the risk of hypoglycaemia at dialysis initiation. As a standard therapeutic approach for decreasing this risk and dis-equilibrium syndrome at our dialysis unit, a continuous venous 5% glucose solution is applied during the glucose-free dialysate (GFD) dialysis. In this interventional study we sought to assess the glycaemic control during standard initiating dialysis protocol versus novel approach with glucose-rich dialysis fluid (GRD).

Material and methods: Twenty-one dialysis patients with chronic renal failure were dialyzed alternatively using GRD (5.6 mmol/l) and GFD fluid. They were not taking any hypoglycaemic medication prior and food during dialysis session. Blood was sampled at regular intervals during dialysis. The dialysis prescription consisted of ultrafiltration (UF) of up to 1 L, membrane surface (MS) up to 1.4 square meters and duration time of 2-2.5 hours. Intra-patient glycaemic variability was defined by Coefficient of variation (CV). In paired analysis t-test was used to determine the glucose control differences in both therapeutic approaches in each patient. For the whole group t-test was used to assess the glucose variability as CV.

Results: The mean age of study participants was 62.95±11.73 years; 7 (33%) had diabetes. The two dialysis approaches did not differ in respect of initial blood pressure, UF and MS. Only two episodes of hypoglycaemia occurred in both types of dialysis. The mean glucose level was higher during GRD (8.15±1.89 vs. 6.29±1.33, p=0.001), respectively. The glucose CV was lower in GRD dialysis when pared t-test was applied, without significant difference (16.97± 8.86 vs. 21.05±11.99, p=0.151). When only diabetic patients were analysed, there was no significant glucose CV difference as well (p=0.151). For the whole cohort glucose variability was significantly higher in glucose-free dialysate dialysis (p=0.0001).

Conclusion: The GRD approach for initiating dialysis sessions is non-inferior to standard GFD care. Dialysate rich in glucose obtains better glucose control during dialysis compared to glucose-free dialysate.

Published: February 2020

Introduction: Cystic fibrosis (CF) is a progressive, life-threatening, genetic disease which mainly damages the lungs and the digestive system. It’s a complex medical condition, with several individual forms and variation in the symptoms severity. Few factors such as age of establishing the diagnosis, the number and the type of infections and their management, best treatment options, comorbid conditions etc. can influence the patient’s overall health, disease progression and quality of life. Many CF patients will reach adulthood, so coping with the chronic disease is very important for the overall health and everyday living.

Aim of the study: To screen the quality of life in CF patients in the Republic of Macedonia, from the parent perspective.

Subjects and methods: In the study we have included 55 parents of CF patients. We have created a questionnaire, specially designed for this survey, with questions related to their everyday coping with CF and quality of life.

Results: The majority of the parents refer to the overall typical social and emotional life of their children, addressing some difficulties concerning the financial aspect of the disease and still significantly having fear from the stigma in the society.

Conclusion: CF patients and their families in the Republic of Macedonia must overcome many obstacles on daily basis. Despite that, they can still have full and meaningful lives.

Published: February 2020

Background: From the conception onward, certain parameters associated with maternal health may affect foetal body composition, growth and bone mineral content.

The objective of the study was to determine the association between maternal vitamin D and adiponectin status with the anthropometrical measures of newborns, and bone health status measured by Quantitative Ultrasound (QUS) at birth.

Methods: Circulating 25OHD and adiponectin concentration were measured in 73 pregnant women. Correlations with the anthropometrical measures and bone health status in their infants were studied. Bone health was evaluated using QUS with the measurements of speed of sound (SOS, in m/s) and Z score on the right tibia.

Results: There was no significant association between maternal 25OHD and newborn’s anthropometrical measures at birth (weight p=0.35, length p=0.59 and head circumference p=0.47). There was a significant negative correlation between a maternal serum adiponectin and a) weight of infants at birth (R= -0.37, p=0.002); b) birth length (R= -0.31, p=0.008) and c) head circumference (R= -0.29, p=0.014). There was no significant correlation between maternal 25OHD blood levels during pregnancy and SOS in newborns (p=0.48). Additionally, a correlation between maternal adiponectin concentration during pregnancy and SOS in newborns was not significant (p=0.82).

Conclusion: Although a high prevalence of low 25OHD level among pregnant women was found, maternal vitamin D status did not influence growth and bone health of their offspring at birth. Maternal adiponectin levels in plasma showed an inverse relationship with anthropometrical measures of infants at birth, while no correlation with the newborn’s bone health was found.

Published: February 2020

Bu çalışmada temel amaç deve sütü yoğurdunun teknolojik olarak üretilebilirliğinin araştırılmasıdır. Öncelikle, ısıl işlemle deve sütündeki antimikrobiyal maddelerin denatürasyonu ve pH düşüşü ile viskozite üzerindeki etkileri analiz edilmiştir. pH‘da azalma meydana gelmesine rağmen, deve sütünün viskozitesi değişmemiştir. İlk çalışmada deve sütüne 2 farklı ısıl işlem (90Â°C de 20 dk. ve 95Â°C de 20 dk.) uygulanmış ve fermentasyon süresince pH 4,7‘ ye ulaşana kadar pH ve SH değerleri saptanmıştır. Kültür ilavesinden sonra 90Â°C de 20 dakika ısıl işleme tabi tutulmuş sütte pH düşüşü 95Â°C de 20 dk ısıtılan sütteki pH düşüşüne göre daha yavaş gerçekleşmiştir. Benzer şekilde 90Â°C de 20 dakika ısıl işlem uygulanmış kültürlenmiş sütte SH artışı 95Â°C de 20 dk ısıtılmış sütteki SH artışına göre daha yavaş gerçekleşmiştir. Bir sonraki çalışmada inek ve deve sütünden yoğurt üretiminde viskozite ve pH değişimleri karşılaştırılmıştır. Bunun için her iki süte 80Â°C‘de 20 dakika ısıl işlem uygulanmıştır. İnek sütünde 180 dakika sonra viskozite 9891 mPa.s iken 210 dakika sonunda 25237 mPa.s‘ye ulaşmıştır. Buna karşın kültürlenmiş deve sütünde 90 dakika sonra viskozite 1210 mPa.s olarak saptanırken 380 dakika sonra viskozite 1216 mPa.s civarında kalmıştır. Gerek deve sütünün gerekse, deve kolostrumunun antimikrobiyal etkisini saptamak için E. coli, L. bulgaricus ve Listeria innocua kullanılmıştır. Deve sütü ve kolostrumunun E. coli, L. bulgaricus üzerine inhibisyon etkisi görülürken, Listeria innocua‘yı inhibe etmediği saptanmıştır.

Published: February 2020

FAO 2017 verilerine göre, dünya bal üretiminde Türkiye Çin‘den sonra ikinci sırada olup; koloni sayısı bakımından üçüncü sırada yer almaktadır. Ancak, Türkiye koloni başı bal verimi bakımından ön sıralarda yer alamamaktadır. Türkiye İstatistik Kurumu (TÜİK) verilerine göre Türkiye‘nin toplam kovan sayısı 2018 yılında 7.904.502, bal üretimi 107.920 ton olarak belirlenmişken; ortalama bal verimi 13,7 kg olarak hesaplanmıştır. Gelecek yıllarda kovan sayısı ve bal verimindeki değişimin nasıl olacağının öngörülmesi ile arıcılara ve politika yapıcılara önbilgi verilmesi ekonomik açıdan önem arz etmektedir. Bu nedenle çalışmada geçmiş yıllara ait kovan sayısı ve bal verimleri kullanılarak, gelecek 5 yıla ait üretim değerlerini tahmin etmek amaçlanmıştır. Bu amaç için son 50 yıllık döneme ait (1969-2018) veriler kullanılarak, beş yıllık (2019-2023) tahminde bulunulmuştur. TÜİK ve FAO‘dan elde edilen verilere kovan sayısı ve bal verimi için ARIMA (1,1,0) birinci derece otoregresif zaman serisi modeli kullanılmıştır. Verilerin analizinde SPSS programından yararlanılmıştır. Elde edilen sonuçlara göre, 2018 yılına kıyasla 2019 ve 2023 yılları arasında koloni sayısında %1,3 ile %7,4 arasında artış beklenmektedir. Ayrıca, bal veriminin 2018'e göre %2,77 ile %3,12 arasında artması beklenmektedir. Koloni sayısının artması ve koloni başına bal veriminin daha az artmasının beklenmesi, önümüzdeki yıllarda üretim maliyetlerini artıracağı için tüketiciler bal ve bal arısı ürünlerini daha yüksek bir fiyata tüketeceklerdir. Sonuç olarak, arıcılar, koloni sayısının arttırılmasının yanı sıra arıcılık ekonomisine, tüketicilere ve ülke ekonomisine yönelik koloni başına bal verimini arttırmaya özen göstermelidir.

Uygulamalardan sonra erikler modifiye atmosfer poşetlerine (MAP) yerleştirilmiş ve 0,5±0,5Â°C‘de %85-90 oransal nem koşullarında 40 gün süreyle depolanmıştır. Meyve kalite özelliklerini belirlemek amacıyla 10 gün arayla ağırlık kaybı, suda çözünür kuru madde miktarı, titre edilebilir asit miktarı, meyve eti sertliği, askorbik asit miktarı, toplam flavonoid miktarı, toplam fenolik madde miktarı ve toplam antioksidan miktarı analizleri yapılmıştır. Elde edilen sonuçlara göre uygulamaların ağırlık kaybına etkisi önemli bulunmamıştır. Depolama süresince meyve eti sertliği, titre edilebilir asit ve askorbik asit miktarında en fazla azalış kontrol meyvelerinde belirlenmiştir. Genel olarak biyokimyasal bileşiklerde artış veya azalış şeklinde dalgalanmalar olmakla birlikte, muhafaza süresi sonunda hasat değerine göre azalmalar meydana gelmiştir. Tüm analiz dönemleri ve yapılan ölçümler dikkate alındığında salisilik asit ve putresin uygulamasının diğer uygulamalara göre depolama süresince Autumn Giant erik çeşidinin meyve kalite özellikleri ve biyokimyasal içeriğinin korunumu üzerine daha olumlu etki gösterdiği tespit edilmiştir.

Pertanian di Indonesia umumnya masih dilakukan secara sangat sederhana dengan mengandalkan tenaga manusia dan hewan. Jorong Koto Gadang merupakan daerah yang berpotensi untuk bercocok tanam holtikultura seperti tomat, cabe, kol, dan sayur-sayuran lainnya. Lahan yang tersedia lebih kurang seluas 20 ha, tetapi tergarap semua oleh masyarakat. ini disebabkan petani masih menggunakan peralatan manual (cangkul) untuk mengolah lahan yang ada. Selain itu pekerjaan mencangkul yang relatif lama akan dapat menyebabkan resiko cedera pada beberapa bagian anggota tubuh (Musculoskeletal Disorders/MSDs). Dirasakan sangat perlu memanfaatkan teknologi yang telah untuk memudahkan pekerjaan petani dan mengurangi resiko cedera tersebut. Berdasarkan asesmen awal dengan REBA diperoleh skor awal 10 artinya resiko levelnya sangat tinggi dan tindakan perbaikan perlu saat ini juga. Teknologi yang dapat digunakan adalah menggunakan cultivator. Pemilihan cultivator ini diperoleh dari diskusi dengan anggota Kube dengan melihat kondisi lahan dan fungsinya. Selanjutnya dilakukan asesmen kembali dengan REBA dan memperlihatkan hasil lebih baik dengan skor 7 yang artinya masih perlu perbaikan. Perbaikan dapat dilakukan dengan memodifikasi alat dan jenis material alat tersebut.

ABSTRACT

Agriculture in Indonesia is generally still done very simply by relying on human and animal labor. Jorong Koto Gadang is an area that has the potential to grow horticulture such as tomatoes, chilies, cabbage, and other vegetables. The available land area is approximately 20 hectares, but it is cultivated by the community. this is due to farmers still using manual equipment (hoes) to cultivate existing land. In addition, relatively long hoeing work can cause the risk of injury to some parts of the body (Musculoskeletal Disorders / MSDs). It is felt that it is necessary to utilize technology that has made it easier for farmers to work and reduce the risk of injury. Based on the initial assessment with REBA an initial score of 10 means that the level of risk is very high and corrective action is necessary at this time. The technology that can be used is to use a cultivator. The selection of cultivators was obtained from discussions with Kube members by looking at the condition of the land and its functions. Furthermore, the assessment was carried out again with REBA and showed better results with a score of 7 which means it still needs improvement. Improvements can be made by modifying the tool and the type of material the tool is.

Reflexões sobre a relação entre resistência à insulina, diabetes mellitus e obesidade na adolescência à luz da literatura
Authors: Oliveira Vanessa Passos , Carvalho Layonne de Sousa , Da Paz Suzana Maria Rebêlo Sampaio , Dos Santos Marize Melo
Published: February 2020

Objetivo: Revisar a literatura sobre os estudos que retratam a resistência à insulina, diabetes mellitus e obesidade na adolescência. Revisão bibliográfica: A insulina é um hormônio anabólico secretado pelas células-beta do pâncreas, tendo funções metabólicas que incluem: captação de glicose, aumento da síntese de proteínas, ácidos graxos e glicogênio. Alterações na função da insulina podem estar relacionadas a diversos fatores extrínsecos como mudanças nos hábitos alimentares e sedentarismo, e intrínsecos como, obesidade. O acúmulo excessivo de gordura corporal, principalmente a visceral, favorece a elevação de ácidos graxos livres na corrente sanguínea, os quais podem prejudicar a sinalização da insulina, diminuir a sensibilidade dos receptores nas membranas celulares e criar o quadro de resistência insulínica, que poderá levar ao surgimento de diabetes mellitus. Existe concordância no meio científico que a obesidade, especialmente em crianças e adolescentes, pode favorecer a identificação precoce de fatores que influenciam o surgimento de síndrome metabólica e diabetes mellitus. Considerações finais: A obesidade, principalmente a visceral, e o próprio DM estão relacionados ao maior risco de desenvolvimento de RI e outras complicações metabólicas em adolescentes.

Paraspinal Fat Stranding as an Unexpected Finding on Body Computed Tomography: A Key to Early Detection of Spinal Osteomyelitis
Authors: Chen Eric L. , Rosenberg Michael , Saran Nitu , Ozgen Burce , Xie Karen , Mar Winnie A.
Published: February 2020

Objective:

At present, early detection of spinal osteomyelitis is a challenge. Patients may present with non-specific symptoms and diagnostic imaging studies may be obtained for seemingly unrelated complaints. Paraspinal fat stranding on body computed tomography (CT) as a sign of osteomyelitis is easily overlooked and has not been reported in the literature to our knowledge. The purpose of this study is to review findings on body CT that points to unsuspected spinal osteomyelitis.

Material and Methods:

A retrospective review of patients with spinal osteomyelitis who also had concomitant chest, abdominal, or pelvic CT scans between August 2013 and February 2017 yielded 10 patients who had confirmed osteomyelitis (ages between 51 and 75, mean age 64.8). Images and medical records were reviewed.

Results:

The age of the patients ranged from 51 to 75 years (median value, 64). All patients had multiple underlying medical illnesses, and half of them had a known preceding infection such as sepsis or urinary tract infection. At presentation, three patients had a fever and two patients had neurologic deficits. Seven out of eight patients had elevated C-reactive protein and erythrocyte sedimentation rate, five patients had leukocytosis, and four patients had positive blood cultures. Paravertebral fat stranding and endplate erosions were observed in 9 and 6 cases, respectively, on initial body CT for unrelated indications, and subsequent magnetic resonance imaging confirmed osteomyelitis discitis.

Conclusion:

Clinically significant, but initially unsuspected, spinal pathology such as osteomyelitis may present on body CT scans. Earlier diagnosis of spinal osteomyelitis can be made by performing a focused evaluation of the paraspinal soft tissues and including osteomyelitis in the differential diagnosis, particularly in high-risk patients.
Keyhole clipping of a low-lying basilar apex aneurysm without posterior clinoidectomy utilizing endoscopic indocyanine green video angiography
Authors: Wong Andrew K. , Wong Ricky H.
Published: February 2020

Background:

Basilar apex (BX) aneurysms are surgically challenging due to their anatomic location, need to traverse neurovascular structures, and proximity to multiple perforator arteries. Surgical approaches often require extensive bone resection and neurovascular manipulation. Visualization of low-lying BX aneurysms is typically obscured by the posterior clinoid and upper clivus and poses a unique challenge. Subtemporal or anterolateral approaches with a posterior clinoidectomy are often required to achieve adequate exposure, though these maneuvers can add invasiveness, risk, and morbidity to the procedure. Endoscopes and, more recently, fluoroscopic angiography capable endoscopes offer the possibility of providing improved visualization with less exposure allowing for minimally invasive clipping.

Case Description:

We present the case of a 42-year-old female with incidentally found 5 mm middle cerebral artery and 5 mm BX aneurysms. She underwent a minimally invasive supraorbital keyhole craniotomy for the clipping of both aneurysms. While the posterior clinoid obstructed the necessary visualization for the BX aneurysm, use of endoscopy and endoscopic fluoroscopic angiography allowed for safe and successful clipping without the need for a posterior clinoidectomy.

Conclusion:

This represents the first reported case of a BX aneurysm clipping through a minimally invasive keyhole craniotomy using endoscopic indocyanine green video angiography. Use of endoscopic indocyanine green angiography, combined with keyhole endoscopic approaches, allows for safe minimally invasive clipping of challenging posterior circulation aneurysms.

Saving Constraints, Debt, and the Credit Market Response to Fiscal Stimulus
Authors: Miranda-Pinto Jorge , Murphy Daniel , Walsh Kieran James , Young Eric R.
Published: February 2020

We document that the interest rate response to fiscal stimulus (IRRF) is lower in countries with high inequality or high household debt. To interpret this evidence we develop a model in which households take on debt to maintain a consumption threshold (saving constraint). Now debt-burdened, these households use additional income to deleverage. In economies with more debt-burdened households, increases in government spending tighten credit conditions less (relax credit conditions more), leading to smaller increases (larger declines) in the interest rate. Our theoretical framework predicts that the negative relationship between the IRRF and debt only holds when credit is not restricted. It also predicts that the consumption response to fiscal stimulus is falling in debt and inequality (only during periods of relaxed credit). We perform a series of empirical tests and find support for these predictions. In doing so, we provide context to recent evidence on the debt-dependent effects of government spending by highlighting that the relationship between debt and fiscal effects varies with credit conditions.
