Fixation of Multiple-Segmented Costosternal Cartilage Fracture in Flail Chest Injury: A Case Report

Early internal fixation of rib fractures in the setting of flail chest has proven benefits over traditional conservative treatment. This can decrease pneumonia, time on mechanical ventilation, length of stay in intensive care units, need for tracheostomy and increase in the pulmonary function test. However, there are few reports regarding on how to restore the costochondral junction, or costal cartilage in cases of anterior or anterolateral flail chest involving cartilage matrix of the ribs or costochondral joint. This case report describes a surgical technique to restore the costochondral junction with plate osteosynthesis and the results.

What Is Most Suitable for Children With Cystic Fibrosis—The Relationship Between Spirometry, Oscillometry, and Multiple Breath Nitrogen Washout

IntroductionIn cystic fibrosis (CF), pathological lung changes begin early in life. The technological progress currently gives many diagnostic possibilities. However, pulmonary function testing in children remains problematic.ObjectivesOur study aimed to correlate the results of impulse oscillometry (IOS) with those of multiple breath nitrogen washout (MBNW) in our pediatric CF population. We also compared those parameters between the groups with and without spirometric features of obturation.MethodsWe collected 150 pulmonary function test sets, including spirometry, IOS, and MBNW in patients with CF aged 12.08 ± 3.85 years [6–18]. The study group was divided into two subgroups: IA (without obturation) and IB (with obturation). We also compared Sacin, Scond, and oscillometry parameters of 20 patients aged 14–18 years who reached the appropriate tidal volume (VT) during MBNW.ResultsStatistical analysis showed a negative correlation between lung clearance index (LCI) and spimoetric parameters. Comparison of subgroups IA (n = 102) and IB (n = 48) indicated a statistically significant difference in LCI (p < 0.001) and FEV1z-score (p < 0.001), FEV1% pred (p < 0.001), MEF25z-score (p < 0.001), MEF50 z-score (p < 0.001), MEF75 z-score (p < 0.001), R5% pred (p < 0.05), and R20% pred (p < 0.01). LCI higher than 7.91 was found in 75.33% of the study group, in subgroup IB—91.67%, and IA−67.6%.ConclusionsLCI derived from MBNW may be a better tool than IOS for assessing pulmonary function in patients with CF, particularly those who cannot perform spirometry.

Therapeutic Effects of a Newly Developed 3D Magnetic Finger Rehabilitation Device in Subacute Stroke Patients: A Pilot Study

We developed a magnetic-force-based three-dimensional (3D) rehabilitation device that can perform motor rehabilitation treatment for paralyzed fingers, regardless of upper extremity movement and position, and investigated the therapeutic effects of the device. An end-effector type rehabilitation device that can generate magnetic fields in three directions was developed using electromagnets and permanent magnetics. A double-blinded randomized controlled pilot study was conducted with a total of 12 patients. The intervention group had rehabilitation treatment using the developed magnetic finger rehabilitation device for 30 min a day for four weeks. The control group underwent exercise rehabilitation treatment. The control group received conventional occupational therapy on the upper limbs, including hands, from an occupational therapist, for the same amount of time. Adverse effects were monitored, and the patient’s sensory or proprioceptive deficits were examined before the intervention. No participants reported safety concerns while the intervention was conducted. The Wolf Motor Function Test (WMFT) scores were significantly improved in the intervention group (from 13.4 ± 3.6 to 20.9 ± 4.0 points) compared to the control group (from 13.1 ± 4.0 to 15.2 ± 3.8 points) (p = 0.016). The patients in the intervention group (from 88 ± 12 to 67 ± 13 s) showed greater improvement of WMFT times compared to the control group (from 89 ± 10 to 73 ± 11 s) (p = 0.042). The Manual Function Test and the upper limb score of the Fugl-Meyer Assessment were significantly improved in the intervention group compared with the control group (p = 0.038 and p = 0.042). The patients in the intervention group also showed significantly greater enhancement of the Korean version of the modified Barthel Index than the control group (p = 0.042). Rehabilitation treatment using the 3D magnetic-force-driven finger rehabilitation device helped improve finger motor function and activities of daily living in subacute stroke patients.

Postinfectious Bronchiolitis Obliterans

Childhood bronchiolitis obliterans (BO) is an uncommon complication that is characterized clinically by persistent and continuous obstructive respiratory symptoms, and has been described secondary to various etiologic factors, including drugs, exposure to toxic fumes, allergic reactions, collagen vascular disease or infections. BO occurs most commonly in children after an episode of acute bronchiolitis and is considered a long-term sequela of viral infection.Postinfectious Bronchiolitis Obliterans (PIBO) is characterized by persistent airway obstruction with functional and radiological evidence of small airway involvement that is in general unresponsive to bronchodilator treatment.Although the condition is relatively rare, and its exact incidence is unknown, it is important to keep it in mind. PIBO is complication of lower respiratory tract epithelial injury, and is often misdiagnosed, delaying recognition and potential treatment. A PIBO diagnosis is usually based on a few factors, including a good medical history, positive clinical findings, and lung function test and imaging results, although biopsy and histopathology remain as the optimum diagnostic approach. There have to date been few studies proposing treatments for the condition, and no accepted protocol exists in literature. There is usually a fixed airway obstruction in PIBO. Various treatment approaches have been extrapolated from studies of post bone marrow transplantations and lung transplant BO. The clinical course is variable, and good supportive therapy is essential, with anti-inflammatory therapy often being employed.

A rare case of Interstitial lung disease complicated by overlapping syndrome with obstructive ventilatory dysfunction as the first symptom

Interstitial lung disease is often a serious complication of connective tissue disease（CTD）, representing the first cause of death in CTD. However, there are few reports of SSc-RA overlap-associated interstitial pneumonia. Respiratory dysfunction as the first clinical manifestation is even rarely reported. We herein described a case of a male patient who developed significant respiratory dysfunction as the principal clinical sign for the past 6 months, plus newly developed skin thickening in bilateral upper limbs and pain and swelling of multiple joints for the past 6 weeks. Extensive immunological screening showed high titer of antinuclear antibodies(ANA), rheumatoid factor(RF), anti-cyclic peptide containing citrulline (anti-CCP)，and positive anti-Scl-70 antibody. Chest high resolution computed tomography(HRCT) was performed and hence ILD was confirmed. Pulmonary function test (PFT) revealed obstructive ventilatory dysfunction rather than restrictive ventilatory dysfunction. So bronchodilation test was performed and asthma was considered. Finally, after a multidisciplinary team (MDT) discussion, the diagnosis of asthma and ILD associated with SSc-RA overlap was established. It is important to note that CTD associated pulmonary interstitial fibrosis must be considered as the differential diagnosis of any newly diagnosed interstitial pulmonary disease. In addition, if patient with dyspnea is highly suspicious of pulmonary interstitial fibrosis, bronchodilation test is still needed to exclude asthma in order to avoid misdiagnosis.

A comprehensive study of diabetic foot ulcer with special reference to magnetic resonance imaging

Background: This pictorial review aims to illustrate the various manifestations of the diabetic foot on magnetic resonance (MR) imaging. The utility of MR imaging and its imaging features in the diagnosis of pedal osteomyelitis are illustrated. There is often difficulty encountered in distinguishing osteomyelitis from neuroarthropathy, both clinically and on imaging. By providing an accurate diagnosis based on imaging, the radiologist plays a significant role in the management of patients with complications of diabetic foot.Methods: This is a prospective and observational study conducted on 50 patients with diabetic foot ulcer admitted in general surgical ward of Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, Bihar. Required pathological or biochemical assessments like complete blood count (CBC), fasting blood sugar (FBS), post prandial blood sugar (PPBS), random blood sugar (RBS), hemoglobin A1c (HbA1C), liver function test (LFT), kidney function test (KFT), serum electrolytes and other relevant investigations will be done on admission. Further magnetic resonance imaging (MRI) will be done in radiological investigations and findings will be noted.Results: In the case of early osteomyelitis, the rate and accuracy of detection is at best 50–60%, as the soft tissues are not adequately demonstrated. For the assessment of soft tissue infection and osteomyelitis involving the foot, MRI is the modality of choice.Conclusions: It has been shown that MRI, in combination with radiography, is the most accurate in the detection of diabetic pedal osteomyelitis and its differentiation from neuroarthropathy. Males are more affected than females in case of soft tissue infections and joint complications.
