Resection of Thumb Metacarpal Ewing Sarcoma and Primary Reconstruction with Non-Vascularized Osteoarticular Metatarsal Autograft

Ewing sarcoma is a primary bone malignancy that rarely occurs in the hand. Resection and reconstruction will usually result in reduced or loss of thumb function. We describe a case of successful transplantation of nonvascularized osteoarticular second metatarsal autograft following wide resection of Ewing sarcoma of first metacarpal in an 11-year-old girl. The capsule of the graft’s metatarso-phalangeal joint was repaired to achieve mobility of the joint. This enabled preservation of thumb function by a relatively simple surgical technique. Detailed surgical procedures and excellence function after 2 years following surgery are described

Giant Pyogenic Granuloma Gravidarum of the Hand

We describe a case of a giant pyogenic granuloma affecting the left index finger of a 23-year-old pregnant lady requiring surgical excision. Pyogenic granuloma gravidarum is a benign hyperplastic lesion that commonly presents on oral mucosa, typically the gums, in approximately 5% of pregnant women. Skin lesions over the fingers are an unusual site during pregnancy with only a few cases reported in the literature. The lesion was excised and a diagnosis of lobular capillary haemangioma was made based on histopathological evaluation. We delayed surgery until after parturition since recurrence is likely to be lower due to lower levels of circulating oestrogen and progesterone. The prognosis is usually excellent following resection. However, recurrences have been reported regardless of the treatment method

Pilot Study on the Effect of Yasiin Recitation on the Haemodynamics of Ventilated Patients

Introduction: Qur’anic verses recitations to ill patients are practiced by many Muslims as a form of healing and worship. The effectiveness has been observed in many medical institutions; however, it has never been objectively measured and documented. This pilot study was conducted to construct a methodological approach to evaluate the therapeutic effects of Yasiin recitation on the haemodynamics of critically ill patients. Methods: Ventilated Muslim patients in coronary care unit of a teaching hospital were evaluated. Yasiin was recited twice; by one of the researchers and then by the patients’ relatives. Mean arterial blood pressure, pulse rate, oxygen saturation level and electrocardiographic changes, were observed. The difference of the parameters before and during recitation was analysed. Results: Five patients fulfilling the selection criteria were selected; two acute myocardial infarctions, two congestive cardiac failures, and a third-degree atrioventricular block. Based on a non-parametric two-related-sample test, the haemodynamic parameters were not significantly affected by Yaasiin recitation. At the end of the study, two of the patients passed away, one patient was extubated and survived. Two patients were still on ventilators when the study had been completed. Limitations in the study were observed and highlighted in explaining the equivocal results. Conclusions: The effect of Yasiin recitation on heamodynamics of patients was not proven in this study. Further refinements might be needed based upon the observation on limitations encountered. It is hoped that this humble effort would pave the way for further studies to explore this field

Early Functional and Radiological Outcomes Between Plaster Cast and Fiberglass Cast in Stable Thoracolumbar Burst Fracture

Introduction: Burst fracture results from compression failure of both the anterior and middle columns under substantial axial loads. Conservative treatment was a method of treatment for fractures without neurological deficit. This cross sectional study was designed to evaluate the functional and radiological outcome of patient with thoracolumbar burst fracture treated conservatively. Methods: 40 cases were recruited from January 2013 till December 2015. They were followed-up with minimum period of 1 year and evaluated for the functional (Oswetry Disbility Index) and radiological outcomes (kyphotic angle deformity and anterior body compression). Results: 20 patients were treated with body cast made form plaster of Paris and remaining 20 patients with fiberglass cast. In plaster of Paris group, mean kyphotic angle deformity at last follow up was 16.60 ± 2.95 with a mean improvement 4.45 degree and anterior body compression at last follow up was 30.35% ± 10.2 with mean improvement of 9.30%. In fiberglass group, mean kyphotic angle deformity at last follow up was 15.55 ± 3.38 with a mean improvement 7.25 degree and anterior body compression at last follow up was 25.90% ± 7.81 with mean improvement of 3.45%. The functional outcome showed Oswetry Disability Index (ODI) score in plaster of Paris group was 23.70 (SD = 7.82) and in fiberglass group was 18.50 (SD = 5.94). Conclusions: Application of body cast using a fiberglass material give better radiological outcome hence less pain, more functional and higher patient’s satisfaction as compared to plaster of Paris

Primary Fixation of AO Type-C Fracture of the Distal Radius with Volar Locking Plates. A Cross-Sectional Study of Patient Rated Outcomes at Hospital Tengku Ampuan Afzan

Introduction: This is a cross-sectional study of 37 patients with AO type C (complete intra-articular) fractures of the distal radius, evaluating the functional, anatomical, and patient rated outcomes one year after primary fixation with a volar locking plate. Methods: Functional outcomes were assessed based on the grip strength, and the range of motion of forearm and wrist. Anatomical outcomes were assessed based on the radial inclination, radial height, volar tilt, and articular step or gap. Patient rated outcome was measured with a Disability of arm, shoulder and hand (DASH) questionnaire. Results: One year after surgery, 24 (64%) patients achieved good and excellent anatomical results, and DASH scores were acceptable in 73% of patients. Most of the patients had achieved 80% of their grip strength. The mean DASH score of 12.3 was comparable with other studies. Grip strength, radial inclination and volar tilt had a significant correlation with the DASH score. Conclusion: Volar locking plates can be used to achieve optimal reduction in all three parameters in the treatment of AO type C fractures of the distal radius. Versatile fracture fragment reduction and angular stability enable rehabilitation hence obtaining good functional outcomes

Outcome of Surgical Treatment of Pelvic Osteosarcoma: Hospital Universiti Sains Malaysia Experience

We reviewed the surgical treatment and outcomes of 13 patients with pelvic osteosarcoma treated in our centre in the past decade. The study sample included 9 males and 4 females with a mean age of 28.1 years. Four patients had ileal lesions, five had acetabulum lesions, one had a ischiopubis lesion, and three had involvement of the whole hemipelvis. Seven patients presented with distant metastases at diagnosis. Limb salvage was performed in 6 patients and amputation in 7. In 60% of cases in the limb salvage surgery group, we attempted wide resection with positive microscopic margin compared to only 16.7% in the amputation group. Local recurrence was higher in the limb salvage group. Overall survival was 18 months for mean follow up of 14.8 months. Median survival was 19 months in the limb salvage group compared to 9 months in amputation group. The outcome of surgical treatment of pelvic osteosarcoma remains poor despite advancements in musculoskeletal oncology treatment

The Study On Range Of Motion Of Hip And Knee In Prayer By Adult Muslim Males. A Preliminary Report

Introduction: Praying represents a fundamental activity of daily living in Muslim community. Muslims need to adopt several postures that require deep flexion of the knee and hip to perform this daily obligation. This is a preliminary report of the study on hip and knee range of motion conducted to obtain normative passive and functional range of flexion data during Muslim prayers in both weight-bearing joints of normal Muslim adults. Methods: A cohort of Malay men aged between 20 to 30 years was recruited in this cross-sectional study. Passive range of motion and flexion angles of the joints in various postures during prayer were measured using a standard goniometer. The difference against existing normative range of motion database available and the influence of various factors were analysed. Factors analysed include body mass index and other anthropometric measurements. Results: Sixty participants recruited for the preliminary phase of this study. The mean (SD) of passive hip and knee flexions were higher compared to other existing normative range of motion database. A unit increase in body mass index will have 0.782 units lower of knee range of motion. The hip and knee flexion arc were from 74.1° to 119.0° and from 3.3° to 119.7° respectively. Conclusion: The range of motion involved for prayers was more for the knee but less for the hip as compared to the measured passive range of motion. Body mass index has a significant linear negative relationship with the passive range of motion of the knee, but not the hip

A nonlinear updating algorithm captures suboptimal inference in the presence of signal-dependent noise

Bayesian models have advanced the idea that humans combine prior beliefs and sensory observations to optimize behavior. How the brain implements Bayes-optimal inference, however, remains poorly understood. Simple behavioral tasks suggest that the brain can flexibly represent probability distributions. An alternative view is that the brain relies on simple algorithms that can implement Bayes-optimal behavior only when the computational demands are low. To distinguish between these alternatives, we devised a task in which Bayes-optimal performance could not be matched by simple algorithms. We asked subjects to estimate and reproduce a time interval by combining prior information with one or two sequential measurements. In the domain of time, measurement noise increases with duration. This property takes the integration of multiple measurements beyond the reach of simple algorithms. We found that subjects were able to update their estimates using the second measurement but their performance was suboptimal, suggesting that they were unable to update full probability distributions. Instead, subjects’ behavior was consistent with an algorithm that predicts upcoming sensory signals, and applies a nonlinear function to errors in prediction to update estimates. These results indicate that the inference strategies employed by humans may deviate from Bayes-optimal integration when the computational demands are high

Islamic Monetary Economics: Insights from the Literature

This chapter reviews critical early literature of Islamic monetary economics. The prohibition of Riba has imposed challenges on Islamic economists to come up with the viable alternatives to achieve Islamic monetary policy goals. Our extensive review of theoretical and empirical literature indicates that equity based profit- and loss-sharing instruments have been proposed for conducting open market operations in an interest-free economy. Theoretically, the central bank can achieve desired goals by controlling money supply and profit-sharing ratios. The findings from empirical literature suggest that money demand tend to be more stable in an interest-free economy. Whether monetary transmission works through Islamic banking channel is controversial, but the literature is growing. These findings are not surprising as majority Muslim countries lack sustainable and equitable economic growth. Moreover, these countries suffer from higher inflation and unemployment with little or no monetary freedom due to fixed exchange rate regime, shallow financial markets and strict capital control

Maternal and Neonatal Morbidity and Mortality Among Pregnant Women With and Without COVID-19 Infection: The INTERCOVID Multinational Cohort Study.

Importance: Detailed information about the association of COVID-19 with outcomes in pregnant individuals compared with not-infected pregnant individuals is much needed. Objective: To evaluate the risks associated with COVID-19 in pregnancy on maternal and neonatal outcomes compared with not-infected, concomitant pregnant individuals. Design, Setting, and Participants: In this cohort study that took place from March to October 2020, involving 43 institutions in 18 countries, 2 unmatched, consecutive, not-infected women were concomitantly enrolled immediately after each infected woman was identified, at any stage of pregnancy or delivery, and at the same level of care to minimize bias. Women and neonates were followed up until hospital discharge. Exposures: COVID-19 in pregnancy determined by laboratory confirmation of COVID-19 and/or radiological pulmonary findings or 2 or more predefined COVID-19 symptoms. Main Outcomes and Measures: The primary outcome measures were indices of (maternal and severe neonatal/perinatal) morbidity and mortality; the individual components of these indices were secondary outcomes. Models for these outcomes were adjusted for country, month entering study, maternal age, and history of morbidity. Results: A total of 706 pregnant women with COVID-19 diagnosis and 1424 pregnant women without COVID-19 diagnosis were enrolled, all with broadly similar demographic characteristics (mean [SD] age, 30.2 [6.1] years). Overweight early in pregnancy occurred in 323 women (48.6%) with COVID-19 diagnosis and 554 women (40.2%) without. Women with COVID-19 diagnosis were at higher risk for preeclampsia/eclampsia (relative risk [RR], 1.76; 95% CI, 1.27-2.43), severe infections (RR, 3.38; 95% CI, 1.63-7.01), intensive care unit admission (RR, 5.04; 95% CI, 3.13-8.10), maternal mortality (RR, 22.3; 95% CI, 2.88-172), preterm birth (RR, 1.59; 95% CI, 1.30-1.94), medically indicated preterm birth (RR, 1.97; 95% CI, 1.56-2.51), severe neonatal morbidity index (RR, 2.66; 95% CI, 1.69-4.18), and severe perinatal morbidity and mortality index (RR, 2.14; 95% CI, 1.66-2.75). Fever and shortness of breath for any duration was associated with increased risk of severe maternal complications (RR, 2.56; 95% CI, 1.92-3.40) and neonatal complications (RR, 4.97; 95% CI, 2.11-11.69). Asymptomatic women with COVID-19 diagnosis remained at higher risk only for maternal morbidity (RR, 1.24; 95% CI, 1.00-1.54) and preeclampsia (RR, 1.63; 95% CI, 1.01-2.63). Among women who tested positive (98.1% by real-time polymerase chain reaction), 54 (13%) of their neonates tested positive. Cesarean delivery (RR, 2.15; 95% CI, 1.18-3.91) but not breastfeeding (RR, 1.10; 95% CI, 0.66-1.85) was associated with increased risk for neonatal test positivity. Conclusions and Relevance: In this multinational cohort study, COVID-19 in pregnancy was associated with consistent and substantial increases in severe maternal morbidity and mortality and neonatal complications when pregnant women with and without COVID-19 diagnosis were compared. The findings should alert pregnant individuals and clinicians to implement strictly all the recommended COVID-19 preventive measures
