Mycobacterium microti infection in the cat: a case report, literature review and recent clinical experience

OVERVIEW: Mycobacterium microti infection is infrequently described in cats in the veterinary literature. It can be one of a large number of possible differential diagnoses in a feline patient with dermal nodules and non-healing draining ulcers, and can occasionally spread to involve the lungs and/or other areas of the body. CASE SUMMARY: This report describes the clinical signs, eventual diagnosis and variable response to treatment in a cat in Switzerland with recurrent cutaneous M microti infection. Only after several diagnostic and therapeutic attempts, over more than 2 years, was the species of Mycobacterium finally identified and targeted therapy given. PRACTICAL RELEVANCE: For any cat in which there is even a low suspicion of mycobacterial infection, the authors recommend that an aggressive diagnostic approach is taken. Tissue specimens should be collected and frozen early on, and, as soon as acid-fast bacilli are detected, samples should be sent to a mycobacterial reference laboratory for definitive identification. LITERATURE REVIEW: A review of the literature relating to the aetiopathogenesis, diagnosis and management of M microti infection in cats and dogs is included. This is supplemented with clinical and therapeutic experience gained from this case and other, unpublished cases managed over the past 15 years by one of the authors (DGM).

Scales of Impact: Settlement History and Landscape Change in the Gordion Region, Central Anatolia

The expansion of agriculture in the Near East during the middle Holocene significantly altered the physical landscape. However, the relationship between the scale of agriculture and the magnitude and timing of the environmental impacts is not well known. The Gordion Regional Survey provides a novel dataset to compare settlement density during archaeological periods to rates of environmental disruption. Sediment samples from alluvial cores directly date the environmental disruption, which can be matched to period-specific settlement intensities in the watershed as constructed from archaeological survey ceramics. Degradation rates rose sharply within a millennium of the earliest Chalcolithic occupation. Early Bronze Age (EBA) land use induced the greatest rates of environmental degradation, although settlement density was relatively low on the landscape. The degradation rate subsequently decreased to one-third its early peak by the Iron Age, even as settlement intensity climbed. This trajectory reveals how complex interaction effects can amplify or subdue the responses of the landscape-land use system. Prior to settlement, landscape soil reservoirs were highly vulnerable, easily tipped by early agricultural expansion. Subsequent reduced rates of erosion are tied both to changes in sociopolitical organization and to depletion of the vulnerable soil supply.

[Kidney and smoking: literature review and focus]

Smoking remains a major public health problem. It is associated with a considerable number of deaths in the world's population. Smoking is just like high blood pressure, an independent predictor of progression to any primary renal disease and renal transplant patients. It seems that smoking cessation slows the progression of kidney disease in smokers. The literature data are sometimes contradictory about it because of some methodological weaknesses. However, experimental models highlight the harmful effects of tobacco by hemodynamic and non-hemodynamic factors. The conclusion is that a major effort should be further produced by the nephrology community to motivate our patients to stop smoking.

Re-thinking Teaching About Atrocity: Human Rights Comparative History and Critical Pedagogy

This paper will explore re-framing historic atrocity and its relationship to Holocaust and Genocide education. The origins of genocide studies and its links to Holocaust studies will be traced to discuss the impact of new scholarship and framings on genocide education in the classroom.

Therapy resistant neonatal seizures, linear vesicular rash, and unusually early neuroradiological changes: incontinentia pigmenti : A case report, literature review and insight into pathogenesis

CASE PRESENTATION: A substance abusing G2P1 mother spontaneously delivered at term an appropriate for gestational age girl. Neonatal seizures appeared at 21 hours and empiric anticonvulsive and antimicrobial treatment was started. At 25 hours, first vesicles appeared. While routine evaluations remained normal, a head CT revealed multifocal ischemic injuries, and a later MRI showed multifocal petechiae and diffusion abnormalities in the corticospinal tracts. The clinical diagnosis of incontinentia pigmenti (stage 1) was secured by histopathology. Follow-up at 13 months showed global developmental delay. DISCUSSION: We discuss the unusually early bilateral, fronto-occipital corticomedullar ischemias (CT day 3). On the MR imaging (day 7) extensive symmetric cerebral corticomedullar destruction and diffusion sequences with corticospinal tracts abnormalities are seen, which then evolve (day 26) to extensive symmetric cerebral destruction. We review the literature, genetics, suspected pathophysiology and possible neonatal manifestation. CONCLUSION: Incontinentia pigmenti is rare and, therefore, diagnosis is frequently delayed. Nevertheless, in the setting of therapy refractory seizures, excluded infections, and linear vesicular rash, a high index of suspicion is needed. This is the first report of simultaneous corticomedullar involvement as early as the third day of life.
