Stenotrophomonas maltophilia (S. maltophilia) is a rare yet important global emerging nosocomial pathogen with multi-drug resistance. To the best of our knowledge, there is only one case report describing the computer tomography (CT) features of S. maltophilia pneumonia. In this article we will compare the features in the published case to those found in our patients. The importance of thoracic CT in febrile neutropenic patients will also be discussed.

Success Of Treatment

Stenotrophomonas maltophilia peritonitis has been only occasionally reported in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Because this microorganism has multi-drug resistance, its treatment is hard and long-term. The treatment might not be successful despite all the efforts and the process of peritoneal dialysis, and may terminate with loss of the catheter. In the present paper, S. maltophilia peritonitis developed in a 6-year-old girl patient, who underwent peritoneal dialysis due to bilateral dysplastic kidney, suffered from episodes of peritonitis frequently and required hospitalization, was presented with literature data. Even though the case received multiple antibiotic treatment and underwent endoluminal brushing (EB), the success of treatment could not be achieved. To the best of our knowledge, this patient is the youngest case in the literature.

Abstract Background The aetiology of pulmonary alveolar microlithiasis (PAM) in animals is still unknown. In humans, this pulmonary disorder is a rare autosomal recessive disorder triggered by a mutation in the gene SLC34A2, which causes deposition and aggregation of calcium and phosphate in the pulmonary parenchyma with formation of microliths. Although histopathological examination is required for a definite diagnosis, in humans, imaging modalities such as computed tomography can demonstrate typical patterns of the disease. This is the first description of the computed tomographic (CT) features of a histologically confirmed PAM in dogs. Case presentation The following report describes a case of a 7-year-old female Boxer dog evaluated for paroxysmal loss of muscle tone and consciousness with excitement. The main differential diagnoses considered were syncope, seizures, and narcolepsy-cataplexy. The results of the complete blood count, serum biochemistry panel, urinalysis, arterial blood pressure, echocardiography, abdominal ultrasound, Holter monitoring, and ECG were all within normal limits. Additional exams included thoracic radiographs, head and thorax CT, bronchoalveolar lavage (BAL), and CT-guided cytology. Thoracic radiographs revealed micronodular calcifications in the lungs, with sandstorm appearance. Computed tomography of the thorax showed the presence of numerous mineralized high-density agglomerates of multiple sizes throughout the pulmonary parenchyma, a reticular pattern with ground glass opacity and intense mineralized fibrosis of the pleural lining. Head CT was unremarkable. BAL and CT-guided cytology were inconclusive, but imaging features strongly suggest the diagnosis of PAM, which was histologically confirmed after necropsy. Conclusions This case report contributes to the clinicopathological and imaging characterization of pulmonary alveolar microlithiasis in dogs. In this species, the diagnosis of PAM should be considered when CT features evidence a reticular pattern with ground glass opacity and the presence of an elevated number and size of calcifications.

Ct Features

Background: computer tomography (CT) features of COVID-19, their temporal changes and differences from other pulmonary (viral and bacterial pneumonia) and non-pulmonary diseases are well described in recent publications. The prevalence and characteristics of signs of concomitant problems that could be identified at chest CT are less studied.Aim: to analyze the prevalence and characteristics of chest CT features of COVID-19, its complications and comorbidities.Methods: retrospective analysis of CT and clinical data of 354 patients hospitalized with suspected COVID at April and May of 2020.Results: 962 CT scans were analyzed (3 (2-3) scans per patient). First CT was performed at 8 (5-11) day of sickness. Several roentgenological scenarios could be highlighted: patients with coronavirus pneumonia (n=295; 83%); with combination of COVID-19 and another pathology (n=36; 10%); with complications of COVID-19 (n=12; 3%); with alternative pathology (n=2; 1%); without any pathological signs (n=9; 3%). Several cases, illustrating CT signs of coronavirus pneumonia, its complications and comorbidities are reported.Conclusion: CT possibilities are not limited to detect typical COVID-19 signs, it also helps to differentiate pulmonary and other thoracis pathology.

Emerging Pathogen

The emergence of C. auris as a global nosocomial pathogen associated with multidrug resistance and high mortality rates has been recently discovered. This emerging pathogen appears to be far more able to induce systemic infection and mortality than other potential multi drug resistance (MDR) yeast pathogens even though it is found to have reduced virulence factors compared to C. albicans. There are issues with regard to the identification of C. auris using both phenotypic and molecular techniques; this has raised concerns about detecting the true scale of the problem. This mini- review elucidates on the literature available on C. auris and highlights the mechanism of pathogenesis and antifungal resistance, which will give further direction to extensive research in this field.

This case report describes a 38-year-old male who was hospitalized for further clarification of clinically mild hyperthyroidism. His increased total hormone levels, the elevated free thyroid hormones and the elevated basal TSH with blunted response to TRH strongly suggested a pituitary adenoma with inappropriate TSH incretion. Transmission computed tomography showed an intrasellar expansion, 16 mm in diameter. The neoplastic TSH production was confirmed by an elevated alpha-subunit and a raised molar alpha-sub/ATSH ratio. However, T4 distribution on prealbumin (PA, TTR), albumin (A) and thyroxine binding globulin (TBG) showed a clearly increased binding to PA (39%), indicating additional prealbumin-associated hyperthyroxinemia. The absolute values of PA, A and TBG were within the normal range. After removal of the TSH-producing adenoma, basal TSH, the free thyroid hormones and T4 binding to prealbumin returned to normal. Therefore, the prealbumin-associated hyperthyroxinemia had to be interpreted as a transitory phenomenon related to secondary hyperthyroidism (T4 shift from thyroxine binding globulin to prealbumin) rather than a genetically conditioned anomaly of protein binding.
