ABSTRACT

In this study, we aimed to show the results of exchange nail and decortication in patients whose subtrochanteric femur fractures were treated with intramedullary nails and subsequently developed fracture nonunion and nail breakage com- plications. This study consisted of patients presenting with subtrochanteric femur fractures between January 2013 and April 2019 who underwent surgery and later experienced nail breakage due to hypertrophic nonunion. There were a total of 10 patients aged 26-62 years (Avg 40,30, SD: 9,989). Nine patients were smokers, and 1 patient had diabetes and hypertension. Three patients were admitted to the trauma center due to a car accident and 7 patients were admitted because of a fall. The infection parameters of all patients were normal. All patients had pathological movement complications and pain at the fracture site. Preoperatively, medulla diameter was measured with standard radiography in all patients. The diameters of the old nails applied to the patients ranged from 10 to 12 mm, and the diameters of the newly applied nails ranged from 14 to 16 mm. The fracture lines of all patients were opened to remove the broken nails, and decortication was performed. No additional autograft or allograft was applied to any patient. Union was achieved in all patients. We conclude that the use of larger diameter nails in conjunction with decortication will prevent nail breakage, improve healing and provide early union in patients with subtrochanteric femur fractures with hypertrophic pseudoarthrosis.

ABSTRACT

Tibial eminentia fractures are avulsion fractures of the anterior cruciate ligament caused with additional injuries like meniscus tears or ligamentous injuries. Arthroscopic assisted internal fixation has become a preferred technique with the development of arthroscopic techniques. We aimed to present our results for arthroscopic assisted double tibial tunnel fixation in patients with displaced eminentia fracture. Twenty patients who were operated on for eminentia fracture between January 2010 and May 2014 were included in this study. All fractures were type II according to Meyers's classification. Eminentia was reduced with two nonabsorbable sutures through the ACL. Two tibial tunnels were created over the medial proximal tibia with a 2.4 mm cannulated drill. The two suture ends taken out of the 2 tibial tunnels were connected on the bone bridge between the tunnels. Patients were evaluated with Lysholm score, Tegner score, IKDC score and examined for clinical and radiological evidence of bony union. Quadriceps exercises were started on the third day. The patients were followed up with a locked knee brace in extension for 3 weeks after surgery and later patients were encouraged to mobilize as pain allowed. The preoperative Lysholm score was 75 ±3.3 and the postoperative Lysholm score was 94.5 ±3. Tegner score was 3.52±1.02 preoperatively and 6.84±1.099 postoperatively. International Knee Documentation Committee(IKDC) score was abnormal in all of the 20 patients preoperatively but normal postoperatively. The postoperative scores of the patients were statistically significant when compared with preoperative activity scores(p<0,0001). Tibial eminentia fractures may lead to pain, knee instability, malunion, laxity, or extension deficit. The technique we have described together with early rehabilitation may give good clinical results.

ABSTRACT

OBJECTIVE: There is little evidence related to the effects of the Omicron severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant on pregnancy outcomes, particularly in unvaccinated women. This study aimed to compare pregnancy outcomes of unvaccinated women infected with SARS-CoV-2 during the pre-Delta, Delta and Omicron waves. METHODS: This was a retrospective cohort study conducted at two tertiary care facilities: Sancaktepe Training and Research Hospital, Istanbul, Turkey, and St George's University Hospitals NHS Foundation Trust, London, UK. Included were women who tested positive for SARS-CoV-2 by real-time reverse-transcription polymerase chain reaction (RT-PCR) during pregnancy, between 1 April 2020 and 14 February 2022. The cohort was divided into three periods according to the date of their positive RT-PCR test: (i) pre-Delta (1 April 2020 to 8 June 2021 in Turkey, and 1 April 2020 to 31 July 2021 in the UK), (ii) Delta (9 June 2021 to 27 December 2021 in Turkey, and 1 August 2021 to 27 December 2021 in the UK) and (iii) Omicron (after 27 December 2021 in both Turkey and the UK). Baseline data collected included maternal age, parity, body mass index, gestational age at diagnosis and comorbidities. The primary outcome was the need for oxygen supplementation, classified as oxygen support via nasal cannula or breather mask, non-invasive mechanical ventilation with continuous positive airway pressure (CPAP) or high-flow oxygen, mechanical ventilation with intubation, or extracorporeal membrane oxygenation (ECMO). Inferences were made after balancing of confounders, using an evolutionary search algorithm. Selected confounders were maternal age, body mass index and gestational age at diagnosis of infection. RESULTS: During the study period, 1286 unvaccinated pregnant women with RT-PCR-proven SARS-CoV-2 infection were identified, comprising 870 cases during the pre-Delta period, 339 during the Delta wave and 77 during the Omicron wave. In the confounder-balanced cohort, infection during the Delta wave vs during the pre-Delta period was associated with increased need for nasal oxygen support (risk ratio (RR), 2.53 (95% CI, 1.75-3.65); P < 0.001), CPAP or high-flow oxygen (RR, 2.50 (95% CI, 1.37-4.56); P = 0.002), mechanical ventilation (RR, 4.20 (95% CI, 1.60-11.0); P = 0.003) and ECMO (RR, 11.0 (95% CI, 1.43-84.7); P = 0.021). The maternal mortality rate was 3.6-fold higher during the Delta wave compared to the pre-Delta period (5.3% vs 1.5%, P = 0.010). Infection during the Omicron wave was associated with a similar need for nasal oxygen support (RR, 0.62 (95% CI, 0.25-1.55); P = 0.251), CPAP or high-flow oxygen (RR, 1.07 (95% CI, 0.36-3.12); P = 0.906) and mechanical ventilation (RR, 0.44 (95% CI, 0.06-3.45); P = 0.438) with that in the pre-Delta period. The maternal mortality rate was similar during the Omicron wave and the pre-Delta period (1.3% vs 1.3%, P = 0.999). The need for nasal oxygen support during the Omicron wave was significantly lower compared to the Delta wave (RR, 0.26 (95% CI, 0.11-0.64); P = 0.003). Perinatal outcomes were available for a subset of the confounder-balanced cohort. Preterm birth before 34 weeks' gestation was significantly increased during the Delta wave compared with the pre-Delta period (15.4% vs 4.9%, P < 0.001). CONCLUSIONS: Among unvaccinated pregnant women, SARS-CoV-2 infection during the Delta wave, in comparison to the pre-Delta period, was associated with increased requirement for oxygen support (including ECMO) and higher maternal mortality. Disease severity and pregnancy complications were similar between the Omicron wave and pre-Delta period. SARS-CoV-2 infection of unvaccinated pregnant women carries considerable risks of morbidity and mortality regardless of variant, and vaccination remains key. Miscommunication of the risks of Omicron infection may impact adversely vaccination uptake among pregnant women, who are at increased risk of complications related to SARS-CoV-2. © 2022 The Authors.

ABSTRACT

OBJECTIVE: We aimed to investigate the vasoactive effects of dexmedetomidine on isolated human umbilical arteries and possible mechanisms involved. METHODS: Human umbilical artery strips were suspended in Krebs-Henseleit solution and dose-response curves were obtained for cumulative dexmedetomidine before and after incubation with different agents; propranolol, atropine, yohimbine, prazosin, indomethacin, verapamil. Effects of calcium on cumulative dexmedetomidine-induced contractions were also studied. RESULTS: Cumulative dexmedetomidine resulted in dose dependent contraction responses. Incubation with propranolol (Emax: 93.3 ± 3.26 %), atropine (Emax: 92.0 ± 6.54 %), or indomethacin (Emax: 94.25 ± 2.62 %), did not attenuate dexmedetomidine-elicited contractions (p > 0.05). There were significant decreases in the contraction responses of cumulative dexmedetomidine with yohimbine (Emax: 12.1 ± 11.9 %), prazosin (Emax: 28.8 ± 4.6 %) and verapamil (Emax: 11.2 ± 13.6 %) (p < 0.05). In Ca+2 free medium contraction responses to cumulative dexmedetomidine was insignificant (Emax: 5.20 ± 3.42 %). Addition of cumulative calcium to the Ca+2 free medium resulted in concentration dependent increase in contractions (Emax: 64.83 ± 37.7 %) (p < 0.05). CONCLUSION: Dexmedetomidine induces vasoconstriction in endothelial-free umbilical arteries via both, α1- and α2-adrenergic receptors and also extracellular Ca+2 concentrations play a major role. ß-adrenergic receptors, muscarinic cholinergic receptors, and inhibition of cyclooxygenase enzyme are not involved in this vasoconstriction (Fig. 3, Ref. 36).

ABSTRACT

Mallet fracture is an avulsion of the extensor tendon and fracture of the dorsal rim of the articular surface of distal phalanx at the same time. If a part of the mallet fracture is angled or rotated to such a degree that prevents full anatomic reduction, malunion and deformities may occur as a result. The objective of this study was to describe a new surgical technique to provide derotation of the mallet fracture. A 22G or 21G needle is used like a joystick to reduce the mallet fracture with small, gentle movements. The extension block pinning technique described by Ishiguro was applied after proper alignment had been achieved. Bony union was achieved for all patients 6 weeks later. Derotation of type 2 and 3 mallet pieces with closed reduction to prevent surgical failure is simple but effective.

ABSTRACT

The interaction between hydrogen and carbonaceous nanostructures is of fundamental interest in various areas of physical chemistry. In this contribution we have revisited the physisorption of hydrogen molecules and H2 clusters on fullerenes, following a first-principles approach in which the interaction is quantitatively evaluated for the C20 system using high-level electronic structure methods. Relative to coupled cluster data at the level of single, double, and perturbative triple excitations taken as a benchmark, the results for rotationally averaged physisorbed H2 show a good performance of MP2 variants and symmetry-adapted perturbation theory, but significant deviations and basis set convergence issues are found for dispersion-corrected density functional theory. These electronic structure data are fitted to produce effective coarse-grained potentials for use in larger systems such as C60-H2. Using path-integral molecular dynamics, the potentials are also applied to parahydrogen clusters solvated around fullerenes, across the regime where the first solvation shell becomes complete and as a function of increasing temperature. For C60 our findings indicate a sensible dependence of the critical solvation size on the underlying potential. As the temperature is increased, a competition is found between the surface and radial expansions of the solvation shell, with one molecule popping away at intermediate temperatures but getting reinserted at even higher temperatures.

ABSTRACT

OBJECTIVE: Although the relationship between obesity-asthma, obesity-atrial fibrillation (AF) and obesity-sudden cardiac death is clearly known, the risk of AF and ventricular arrhythmia has not been clearly determined in asthmatic patients. The aim of this study was to investigate whether AF, ventricular arrhythmia, and sudden cardiac death risk were increased in asthmatic patients using P wave dispersion (PWD) and corrected QT interval dispersion (CQTD). PATIENTS AND METHODS: The study was designed as a cross-sectional study. A total of 164 participants (88 patients with asthma and 76 healthy volunteers) were enrolled into the study. PWD and CQTD were measured and recorded in both groups. The statistical difference between the two groups was examined. RESULTS: PWD was higher in the asthma patients than in control subjects (31.53 ± 3.18 vs. 30.33 ± 3.53, p = 0.023). However, there was no statistically difference between the groups in terms of CQTD measurement (43.9 ± 1.84 vs. 43.63 ± 2.06, p = 0.385). In comparison between control group and asthma subgroups (mild, moderate and severe), there was a statistically significant difference among these four groups in terms of PWD (p = 0.017). Subgroup analyses showed that this difference was mainly due to patients with severe asthma. CONCLUSIONS: PWD value was elevated in asthmatic compared to the control group. The CQTD was not statistically significant between the groups. These results indicate that the risk of developing AF in asthmatic patients might be higher than in the normal population. Ventricular arrhythmia and sudden cardiac death risk may not be high in asthmatic patients.

ABSTRACT

Scaphoid non-union management is still a challenge in clinical practice for orthopaedic surgeons. Though several treatment methods have been described, there is an ongoing debate about optimum management. Based on new concepts about avascular conditions, promising results were reported with metaphyseal decompression of the distal radius by increasing the vascularization of the radial column of the carpus. We aimed to evaluate the clinical, radiological, and functional outcomes of distal radius core decompression and fixation with palmar percutaneous cannulated compression screws without grafting in patients with scaphoid waist fracture non-union. Twenty-nine patients with scaphoid non-union were included in this prospective study. There were 27 male and 2 female patients with an average age of 29 years (range 18-45 years). Mean time from the injury to surgery was 18.3 months. The Slade and Geissler classification was used to classify the non-unions. Wrist range of motion (ROM), pain based on a visual analog scale (VAS), and the Mayo wrist score were used to assess the clinical outcomes. Postoperative radiographs and CT-scans were reviewed to assess fracture union, carpal alignment and screw position. The average clinical follow-up was 76 weeks (range: 74-87 weeks) postoperatively. Mean time to union was 11 weeks (range: 7-18 weeks). There was no humpback/no DISI in any of the cases. Twenty-six patients healed successfully with no additional procedures. Three patients with failed union underwent revision surgery with grafting. At the final follow-up, average wrist ROM was 61° (range: 30-80) in extension and 61° (range: 35-80) in flexion, the average Mayo wrist score was 66±20 (range: 20-90), and the mean VAS was 2±2 (range: 0-7). Percutaneous fixation without grafting associated with distal radius core decompression can provide satisfactory outcomes in surgical management of scaphoid non-unions. LEVEL OF EVIDENCE: II.

ABSTRACT

Phytochemicals such as curcumin have great potential in cancer prevention and treatment. However, instability and low aqueous solubility of free curcumin weaken its anticancer potential. These undesirable problems can be avoided upon loading curcumin into nanoparticles containing biocompatible and biodegradable polymers such as poly lactic-co-glycolic acid (PLGA), liposomes or micelles. The interaction of drugs and release control can be further enhanced upon inclusion of clay minerals into the PLGA containing nanoparticles. Such nanoparticles offer a new way for cancer drug delivery systems. However, the role of the clay mineral in the resulting composite is not fully understood. Therefore, in this study, we carried out systematic adsorption studies of curcumin anticancer drug on montmorillonite (MMT) nanoparticles in the presence of amphiphilic polymer (PLGA) and in an aqueous environment to understand the contribution of the layered clay structure using cluster (B97-D), periodic DFT and molecular dynamics (MD) simulations in acidic and natural pH media. It has been found that MMT has high affinity towards either polymer or drug molecules especially due to vdW interactions. Furthermore, it has been observed that MMT facilitates the release of curcumin. Current findings suggest that a composite consisting of MMT and PLGA might be used to deliver the anticancer agent curcumin.

ABSTRACT

The management of severe hepatic artery vasospasm soon after liver transplantation (LT) is challenging because it can lead to hepatic artery thrombosis and subsequent graft failure. A 61-year-old man with hepatitis C cirrhosis and portal vein thrombosis received a deceased donor LT. On postoperative day 1, Doppler ultrasonography revealed a high-resistance waveform in the hepatic artery. Angiography showed severe vasospasm of the donor hepatic artery on postoperative day 3. Strong hepatic arterial buffer response (HABR) was considered for this etiology due to high portal vein velocity. Therefore, vasodilators, including nitroglycerin and prostaglandin E1, were initiated. The waveform of the hepatic artery vasospasm gradually improved as portal vein velocity decreased by Doppler ultrasonography within 7 days after LT. In conclusion, hepatic arterial buffer response can induce hepatic artery vasospasm immediately after LT. This vasospasm type may be managed conservatively with a positive outcome.

ABSTRACT

BACKGROUND AND PURPOSE: Small infants with biliary atresia and hypoplastic portal veins (PV) are at risk for portal vein thrombosis (PVT) after liver transplantation (LT), which can lead to graft loss and mortality. Extra-anatomical PV reconstruction techniques have been established for adult cases of PVT; however, they have not been widely accepted for infants. METHODS: Here, we report the successful use of an extra-anatomical meso-portal venous jump graft to treat early PVT after LT in a 6-month-old infant with biliary atresia and PV hypoplasia. At the time of LT, despite a reduced-sized left lateral graft, we had to create a temporary abdominal closure with silastic mesh. FINDINGS: On postoperative day 1, PVT was detected by Doppler ultrasound of the liver. Surgical thrombectomy was attempted. We removed the blood clots and reconstructed the PV using an interposition venous graft. As the PV flow was still not sufficient, we performed an extra-anatomical meso-portal venous jump graft procedure from the recipient superior mesenteric vein to the donor PV. This resulted in a significant improvement in PV flow. CONCLUSION: For small infants at high risk for PVT, a detailed pretransplantation surgical plan and treatment options for possible early PVT are mandatory. An extra-anatomical meso-portal venous jump graft is a viable surgical technique for early PVT in infants.

ABSTRACT

UNLABELLED: PURPOSE OF THE STUDY Although supracondylar humeral fractures represent a major part of the pediatric fractures, no classification system or radiological characteristics describes which supracondylar fractures require open reduction. We aim to evaluate the factors that lead us to perform open reduction during operation. MATERIAL AND METHODS We retrospectively evaluated 57 patients who underwent operation for type III supracondylar fracture, and divided them into two groups; those with open reduction and internal fixation, and those with closed reduction and percutaneous fixation. The two groups were compared based on age, gender, BMI by age, medial spike angle of the fracture, medial spike-skin distance and rotation angle between the fractured fragments. RESULTS Of all patients, 46 (81.71%) underwent closed reduction and percutaneous fixation (CRPF) and 11 (19.29%) were treated with open reduction and internal fixation (ORIF). BMI by age was remarkably higher in the ORIF group (p = 0.00). And medial spike angle was smaller in the ORIF group (p = 0.014). DISCUSSION Closed reduction and percutanous fixation is the main treatment of supracondylar humeral fractuers. Open reduction in supracondylar humeral fractures could be associate with complications and cosmetic lesions. Many studies indicates that obesity is high risk factor for complex fractures as well as preoperative and postoperative complications. A prominant medial spike could associate with muscle entrapment, and obliquity of the fracture line. It could be also an indirect finding of instablity of the fracture. CONCLUSION We suggest that a smaller medial spike angle and a higher BMI in children with Type III supracondylar humeral fractures may require open reduction, and it is unreasonable to avoid open reduction in cases where closed reduction is not achieved. KEY WORDS: supracondylar humerus, open reduction, obesity, medial spike angle.

ABSTRACT

Variation in the volatiles, total polyphenol, theobromine and caffein was investigated both qualitatively and quantitatively for all phases of conching with GC/MS/SPME, HPLC, GC/O, and UV-visible spectrophotometry. The volatile compounds being identified during the three phases consisted of aldehydes, ketones, pyrazines, acids, alcohols and esters. The number and concentration of these compounds were observed to be 31-25,681 ppb, 44-34,838 ppb and 44-29,809 ppb in the dry, pasty, and liquid phases respectively. The odor of dark chocolate was described as nutty, sweet, caramel, green and chocolate using olfactometry. The percent decrease in the concentration of total polyphenol, caffein and theobromine was observed to be only 3.0, 11.0, and 32.0 respectively.

ABSTRACT

Several clinical and radiological factors can be prognostic in the development of angular deformity following physeal injuries of the distal tibia. One of the radiological parameters, premature physeal closure (PPC), can be detected during postoperative follow-ups. Aim of our study was to identify the prognostic factors in development of angular deformity and its relationship with PPC. One hundred and four patients treated due to physeal injuries of the distal tibia were included in our study. Patients were divided into three groups based on Salter-Harris (SH) classification. The intergroup relationships between sex, age, the amount of energy sustained during injury, premature physeal closure, the amount of residual gap, and deformity were analyzed. Angular deformity developed in 25% (3/12) of SH Type 2, in 60% (9/15) of Type 3 and 30% (3/10) of Type 4 patients with PPC. A residual displacement of more than 2 mm, age and premature physeal closure were specified as significant risk factors for development of angular deformity. 2 mm limit for residual displacement and findings of premature physeal closure in the radiological evaluations during follow-ups are prognostic factors in avoiding malalignment of the distal tibia. LEVEL OF EVIDENCE: Level 3.

ABSTRACT

In the present study, refined dark chocolate mix was conched with the addition of finely powdered cinnamon in a laboratory-style conching machine to evaluate its aroma profile both analytically and sensorially. The analytical determinations were carried out by a combination of solid phase micro extraction (SPME)-gas chromatography (GC)-mass spectroscopy (MS) and-olfactometry(O), while the sensory evaluation was made with trained panelists. The optimum conditions for the SPME were found to be CAR/PDMS as the fiber, 60 °C as the temperature, and 60 min as the time. SPME analyses were carried out at 60 °C for 60 min with toluene as an internal standard. 26 compounds were monitored before and after conching. The unconched sample had a significantly higher fruity odor value than the conched sample. This new product was highly acceptable according to the overall inclination test. However some of textural properties, such as coarseness, and hardness were below the general preference.

ABSTRACT

The presence of elevated calculated panel reactive antibody (cPRA) and anti-HLA donor specific antibodies (DSA) are high risk factors for acute antibody-mediated rejection (AAMR) in intestinal transplantation that may lead to graft loss. Eculizumab has been used for the treatment of AAMR in kidney transplantation of sensitized patients that do not respond to other treatment. Here, we report a case where eculizumab was used to treat AAMR in a desensitization-resistant intestinal re-transplant patient. A male patient lost his intestinal graft to AAMR 8.14 years after his primary transplant. He received a second intestinal graft that had to be explanted a month later due to refractory AAMR. The patient remained highly sensitized despite multiple treatments. He received a multivisceral graft and presented with severe AAMR on day 3 posttransplantation. The AAMR was successfully treated with eculizumab. The patient presently maintains an elevated cPRA level above 90% but his DSAs have decreased from 18 000 MFI (mean fluorescent intensity) to below the positive cut-off value of 3000 MFI and remains rejection free with a 2-year follow-up since his multivisceral transplant. Eculizumab offers an alternative to treat AAMR in intestinal transplantation in desensitization-resistant patients.

ABSTRACT

BACKGROUND: Auxiliary partial orthotopic liver transplantation is an alternative technique for the treatment of patients with fulminant hepatic failure and metabolic liver disease. It provides temporary support of liver function until sufficient regeneration of the native liver. Pediatric patients have a long life expectancy and are best candidates to benefit from the interruption of antirejection treatment. DESCRIPTION OF CASE: A 4-year-old boy underwent auxiliary partial orthotopic liver transplantation for fulminant hepatic failure using a cadaveric left lateral segment of liver. One year after auxiliary partial orthotopic liver transplantation, the patient's native liver was determined to be completely normal and he was doing well. The patient was then gradually weaned from the immunosuppression over the course of one year. The graft was undetectable on follow-up computerized tomography performed before complete cessation of immunosuppression, leading to the diagnosis of "vanishing graft syndrome". CONCLUSION: Graft atrophy commonly occurs after auxiliary partial orthotopic liver transplantation due to cessation of antirejection therapy. But to our knowledge, complete graft disappearance is a rare occurrence reported in the English literature. Timing for withdrawal of the immunosuppression is an important decision to be made in this technique. Hippokratia 2015; 19 (3): 274-277.

We present the case of a child who underwent a combined liver, pancreas and double kidney transplant following complications of Wolcott-Rallison syndrome (WRS) a rare genetic disorder that causes infantile insulin-dependent diabetes mellitus (IDDM) and often death in childhood from fulminant liver and concomitant kidney failure. WRS is characterized clinically through infantile IDDM, propensity for liver failure following viral infections, bone dysplasia and growth failure and developmental delay. Fewer than 60 cases with WRS are reported in the literature, mostly from consanguineous parents. Future episodes of liver failure, the main contributor to the increased mortality in WRS, may be prevented through timely liver transplantation. To the best of our knowledge, transplantation has not been utilized to manage complications of WRS prior to this report.
