Mueller Weiss Syndrome is a rare, under-diagnosed cause of chronic mid foot pain despite having well-described imaging features. It is historically described as spontaneous adult-onset osteonecrosis of the navicular bone. The disease commonly affects bilateral navicular bones in women in the fifth decade of life. Nearly a century after its first description as a disease entity, the exact etiopathogenesis is still not well understood. From a radiographic point of view weight-bearing radiographs of the foot remains the mainstay in diagnosis. Characteristic imaging findings include the lateral collapse of navicular, dorsomedial subluxation of the remnant navicular, and lateral deviation of the talus (hind-foot varus). Progressive disease leads to pes planus and secondary osteoarthritis of the talonavicular joint with or without the involvement of other midfoot joints. Severe disease may show “listhesis navicularis” and talo-cuneiform neo-articulation. Computed tomography and magnetic resonance imaging can be used as adjuncts, especially to detect changes in the initial stage of the disease and early osteoarthritic features.

AbstractOur understanding of the manifestations of pneumoconioses is evolving in recent years. Associations between novel exposures and diffuse interstitial lung disease have been newly recognized. In advanced asbestosis, two types of fibrosis are seen, probably related to dose of exposure, existence of pleural fibrosis, and the host factor status of the individual. In pneumoconiosis of predominant reticular type, nodular opacities are often seen in the early phase. The nodular pattern is centrilobular, although some in metal lung show perilymphatic distribution, mimicking sarcoidosis. High-resolution computed tomography enables a more comprehensive correlation between the pathologic findings and clinically relevant imaging findings. The clinician must understand the spectrum of characteristic imaging features related to both known dust exposures and to historically recent new dust exposures.

Abstract Background Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first identified in December 2019 in Wuhan. This study mainly analyzed the clinical characteristics, imaging features, and prognosis of patients with COVID-19 in Suining, one of China's fourth-tier cities, and Wuhan in 2019 and compared data between the 2 cities. Methods A retrospective analysis of the epidemiological history, clinical data, symptom presentation, laboratory test results, chest computed tomography (CT) imaging features, treatment measures and prognosis of 68 patients with COVID-19 diagnosed at Wuhan Red Cross Hospital and 17 patients with COVID-19 diagnosed at Suining Central Hospital from January 23, 2020, to February 27, 2020, was conducted. Results 1) The incidence rate of COVID-19 in Wuhan was 52.99‱, and the incidence rate in Suining was 0.04‱. The median age of patients with COVID-19 was 40.71 years old in Suining and 56.04 years old in Wuhan. The age of patients with COVID-19 in Wuhan was significantly older than that of patients with COVID-19 in Suining. Among the 68 patients with COVID-19 in Wuhan, 30 (44.1%) had hypertension, and 25 (36.8%) had diabetes. Three out of the 17 patients in Suining (17.6%) had hypertension, and 2 patients (11.8%) had diabetes. The proportion of patients with diabetes or hypertension in Wuhan was significantly higher than that in Suining (P<0.05). In the clinical classification, there were 1 (5.9%) and 23 (33.8%) patients with severe COVID-19 in Suining and Wuhan, respectively. The proportion of patients with severe COVID-19 in Wuhan was significantly higher than that in Suining (P<0.05).Fever and cough were the most common clinical symptoms, with 9 cases (52.9%) and 8 cases (47.1%) in Suining, respectively, and 54 cases (79.4%) and 42 cases (61.8%) in Wuhan, respectively. There was 1 patient (5.9%) with COVID-19 with dyspnea in Suining and 23 patients (33.8%) with COVID-19 with dyspnea in Wuhan; the difference was statistically significant (P<0.05). Chest CT showed that lung consolidation occurred in 2 (11.8%) and 26 (38.2%) patients with COVID-19 in Suining and Wuhan, respectively. The proportion of lung consolidation in patients in Wuhan was significantly higher than that in patients in Suining (P<0.05). The laboratory tests suggested that percentage ofelevated C-reactive protein (CRP) (58.8%), ALT (33.8%), blood glucose (45.6%), creatine kinase (CK) (33.8%) or D-dimer (47.1%) of patients in Wuhan were significantly increased than those in Suining (29.4%, 5.9%, 17.6%, 5.9%, and 17.7%, respectively). Moreover, the average length of hospital stay of patients in Wuhan was 17.49 days, which was significantly longer than that of patients in Suining (12.29 days). Conclusions The incidence of COVID-19 in fourth-tier cities, Suining, in China was significantly lower than that in Wuhan, and the disease severity was generally lower than that in Wuhan, with mostly good prognoses. Advanced age, diabetes, and hypertension are important factors that aggravate COVID-19, while elevated CRP, ALT, blood glucose, CK, and D-dimer levels are important indicators for severe disease.

ABSTRACT Ankle osteoarthritis patients are young and lack of available long last treatment. Ankle arthrodesis remains the gold standard and is the procedure of choice for younger patients who are heavy laborers. These case series evaluate and report five patients undergone ankle arthrodesis at RSUD Dr. Soetomo Surabaya on 2012-2016. The data were collected from patient files, radiographs, and a recent physical examination. The outcome has been assessed with SF-36 score and clinical scoring system Ankle-Hind foot American Foot and Ankle Society. Three male patients and two female patients underwent ankle arthrodesis with cannulated screw, caused by neglected severe ankle dislocation. One patient had open dislocation. Based on SF-36 scoring, the five patients had average score 76,7 with highest and lowest score were 95,9 and 56,7. Based on clinical score ankle-hind foot American Ankle and Foot Society, the average score was 68(51 – 88). The scoring result includes general health, physic, emotional, and social. And clinical scoring ankle-hind foot American Foot and Ankle Society evaluation includes pain, function, and alignment. It shows that there was patient that gains an almost perfect result. Patient with the lowest score also had knee osteoarthritis contralateral from the operated ankle. Early weight bearing on ankle arthrodesis with cannulated screw was the major factor caused unsatisfactory result of this patient. Ankle arthrodesis with cannulated screw has satisfactory result eventhough remain complain on one patient. Nevertheless, ankle arthrodesis with cannulated screw still has an important role in the treatment of choice on ankle reconstruction.Keywords                   : Ankle arthrodesis, cannulated screw, ankle joint fusion

Urological Emergencies

High resolution ultrasound with color Doppler is the first-line imaging investigation in the evaluation of acute scrotum. It plays a crucial role in distinguishing urological emergencies necessitating immediate surgical exploration from those that can be managed conservatively. Acute scrotal pathologies can involve the scrotal sac or its contents like testis, epididymis and testicular appendages and could range from benign, self-limiting conditions to emergencies. In this pictorial essay, we briefly review the ultrasonographic technique, scrotal anatomy and characteristic imaging features of various pathologies presented as acute scrotum.

Initial Clinical Evaluation

Primary malignancy of the urachal remnant is a rare neoplasm that accounts for less than 0.01% of all adult cancers, with an estimated annual incidence of 1:5 million. The tumour carries a grave prognosis that attests to its highly aggressive nature. Owing to its extra-peritoneal location, the tumour runs a relatively silent clinical course until late presentation, when most patients display extensive local invasion and metastatic spread. In this report, we highlight a case of primary malignancy of the urachus that on initial clinical evaluation masqueraded as a Sister Mary Joseph’s nodule. Characteristic imaging features, however, proved decisive in establishing the diagnosis of a urachal carcinoma.

Concrete Hardening

When predicting the growth of strength and maturity of hardening concrete, the role of the temperature factorshould be taken into account. Taking into account the temperature factor requires at the initial stage of hardening of concrete low positive temperatures and low speed of heating concrete. The level of maximum heating of concrete will depend not only on the exothermy of the cement, but also on the amplitude of the fluctuations in the ambient temperature. The contribution to the cracking of concrete of various types of cements from the point of view of heat release during their hydration is analyzed. The existing models for predicting the character of the set of strength and maturity of concrete on the basis of data on heat dissipation during hydration of cement in concrete structures are analyzed. It is shown that laboratory tests are insufficient to evaluate the nature of heat generation. To effectively predict the physical and mechanical properties, it is necessary to conduct temperature-time monitoring during the concrete hardening in the design to take into account the influence of external factors.

Abstract Objective Through the summary and analysis of large samples, the characteristic imaging manifestations of intrapulmonary lymph nodes (IPLNs) were quantified, and two corresponding rating tables were developed. These rating tables could be used to distinguish the IPLNs from primary lung cancer, so as to improve the diagnostic accuracy and help clinicians make correct judgments and decisions. Methods A total of 82 patients with 110 IPLNs and 35 patients with primary lung cancer lesions were collected from June 2017 to December 2018. All lesions were solid nodules of less than 12 mm in diameter, which were confirmed by pathology. Observation indicators included location, size, shape, density, border and internal vacuoles of nodules, linear high-density shadow around the nodules, distance from the pleura, pleural indentation, and so on. Results There were statistically significant differences in the location, size, shape, internal vacuole of the nodules, and distance from the pleura (p < 0.05). The diagnostic scoring table of the nature of solid nodules and the malignant risk table were drawn. The nodule corresponding to Level A was most likely the primary lung cancer, and surgical resection was recommended. The nodule corresponding to Level C was most likely IPLNs, and it was better to receive no treatment currently. The positive predictive value was 81% (23/28), the negative predictive value was 97% (89/92), the sensitivity was 63% (23/35), and the specificity was 81% (89/110). Conclusion For the pulmonary solid nodules of less than 12 mm in diameter and unknown nature, the evaluation in accordance with the Score Table and the Risk Level Table of this study can be more accurate and faster than the original judgment, which will help clinicians in diagnosis and treatment decisions.
