Diabetic ketoacidosis complicated by generalized venous thrombosis: a case report and review.

Venous thromboembolism is a rarely described complication of diabetic ketoacidosis (DKA). We describe a 21-year-old male patient with poorly controlled type 1 diabetes mellitus who was admitted with DKA, presumably secondary to noncompliance, whose clinical picture was complicated by generalized thrombosis involving multiple venous locations including renal vein, pulmonary vasculature, external iliac and common iliac veins. The patient had no family history of any coagulation disorders and a hypercoagulabilty work-up remained negative. The patient was subsequently anticoagulated with heparin and discharged home on warfarin. To the best of our knowledge, this is the first reported case of multiple venous thromboses occurring as a complication of DKA with no other risk factors. We also reiterate that although rare, venous thrombosis should always be considered as a potential complication of DKA.

Sex differences in resting hemodynamics and arterial stiffness following 4 weeks of resistance versus aerobic exercise training in individuals with pre-hypertension to stage 1 hypertension.

BACKGROUND: Hypertension (HTN) exhibits sexual dimorphism; the incidence for women surpasses men during the sixth decade of life, while the pharmacological treatments are less effective and produce more side-effects in women than in men. Aerobic exercise (AE) has been shown to prevent and treat HTN; however, resistance exercise (RE) is not recommended as a strategy to treat HTN. In this study, we investigated the potential sex differences of AE versus RE in a cohort of unmedicated patients with hypertension. METHODS: In total, 40 moderately active, pre-hypertensive or stage 1 essential hypertensive male (M) and female (F) participants aged 40 to 60 years were randomly divided into four groups: M AE, M RE, F AE, and F. Each group exercised at moderate intensity, 3 days/week for 4 weeks. Hemodynamic, vascular and blood-flow data were collected before and after exercise training. RESULTS: Men showed a significant increase in central pulse wave velocity following RE while females showed no significant changes (12 ± to 13.9 ± vs. 9.2 ± to 9.6 ± m/s, respectively). RE showed significantly greater increases in peak blood flow when compared to AE (F RE 15 ± to 20 ± vs. F AE 17.5 ± to19.5 ±, M RE 19 ± to 24 ± vs M AE 21 ± to 25 ± ml* 100 ml*min, respectively). In addition, systolic and diastolic BP decreased greater for women following RE when compared to AE whereas men showed comparable decreases in BP following either exercise mode. CONCLUSION: Moderate-intensity RE training may be a more favorable for women as a treatment option for hypertension because of greater decreases in diastolic BP and significant increases in flow-mediated dilation without concomitant increases in arterial stiffness, compared with their male counterparts.

Occult PTSD with panic attacks in a patient post-TIA: case report.

Affective disorders are common sequelae of cerebrovascular events. A myriad of evidence demonstrates that clinically significant depression can often follow a stroke. However, less is known about the extent to which anxiety disorders present after these experiences, and in particular, post-traumatic stress disorder (PTSD) with panic attacks. To our knowledge, the association between transient ischemic attacks (TIAs) and PTSD with panic attacks has not been described in the literature. Here we describe a patient with depression and PTSD with panic attacks following a transient ischemic attack. Many non-psychiatric physicians learn about post-stroke depression so they are equipped to screen for it. However, to many physicians, PTSD with panic attacks usually conjures the image of an individual who experienced either trauma or rape. Therefore, it is important to increase the awareness of such complications after TIAs. Increased awareness of these TIA sequelae has important implications for detection by non-psychiatric healthcare providers. Furthermore, prompt recognition and treatment has important implications for patient quality of life.

Vertebral osteomyelitis caused by Prevotella (Bacteroides) melaninogenicus.

A 35-year-old, previously healthy female presented with severe low back pain, fever, and a high erythrocyte sedimentation rate 1 week after a routine dental cleaning. Technetium-labeled leukocyte scanning and magnetic resonance imaging scan of the spine were negative for osteomyelitis. The patient underwent biopsy, cultures from which grew Prevotella (Bacteroides) melaninogenicus. Appropriate antibiotic therapy resulted in resolution of symptoms. P. melaninogenicus is a gram-negative anaerobic bacillus that is part of the indigenous oral flora. It may cause dental, sinus, skin, and soft tissue infections. Infection of bone is rare. Only three cases of vertebral osteomyelitis due to P. melaninogenicus have been reported in the literature. The early diagnosis of vertebral osteomyelitis requires a high index of clinical suspicion and cannot be excluded by negative imaging tests alone. The recovery of this unusual organism highlights the importance of requesting anaerobic cultures of biopsy specimens.
