We report a newborn girl (36th week of gestation, birth weight 1,054 g) with Cushing's syndrome secondary to nodular adrenocortical hyperplasia with normal plasma ACTH levels. From birth she was hypertensive, hyperglycaemic and slightly hirsuit. Hypercortisolaemia (>1,380 nmol/l) was accompanied by normal plasma ACTH levels (8.64-23.9 pg/ml). A 48-h dexamethasone suppression test decreased plasma cortisol by 35%, indicating some degree of ACTH dependency. However, there was no ACTH rise on CRF test. MRI showed enlarged adrenal glands with a possible cyst on the right; the pituitary gland was normal. At the age of 6 weeks she underwent bilateral adrenalectomy. Histology showed enlarged adrenals with multiple non-pigmented nodules (up to 5 mm) in both glands. However, over the next few weeks she developed liver failure and sepsis. She died at the age of 3 months. Post mortem examination confirmed the diagnosis. Nodular adrenocortical hyperplasia may present at birth with severe Cushing's syndrome and unsuppressed ACTH levels, indicating some degree of ACTH dependency in this condition.

Acute renal failure (ARF) induced by sepsis has a high mortality but lacks effective treatments. To develop novel therapies we must diagnose renal injury early and accurately in septic patients and identify any additional insults such as nephrotoxic drugs and ischemia. In this short review we describe our experience using MRI with dendrimer-based contrast agents in mouse models of ARF. This technique can diagnose early renal injury before serum creatinine is elevated, distinguish different ARF etiologies, track drug therapy and predict outcome. As an ARF biomarker, MRI with dendrimer-based contrast is a promising technique deserving further development.

Melioidosis which is infection with Burkholderia pseudomallei, is an important cause of sepsis in India, southeast Asia and northern Australia. Mortality is high and treatment is problematic. Neurological melioidosis is unusual but meningoencephalitis, encephalomyelitis and brain microabscess can occur Dural sinus thrombosis is not an uncommon cerebrovascular disorder with various etiologies. Hypercoagulable state, pregnancy, dehydration, certain blood dyscrasia and contraceptive pills are common causes however meningitis and local head & neck infections may lead to this condition. Dural sinus thrombosis complicating septicemic melioidosis has never been reported. The authors report a 42-year-old Thai man suffering from septicemic melioidosis with dural sinus thrombosis. He had high fever, headache, left hemiparesis, focal seizure and increased intracranial pressure. Diabetes and mild alcoholic cirrhosis were diagnosed in this admission. CT scan, MRI brain and MRV revealed superior saggital sinus thrombosis with complicating venous infarction over right posterior parietal lobe. Hemoculture demonstrated Burkholderia pseudomallei and CSF was acellular Investigations for causes of dural sinus thrombosis were all negative. This patient gradually improved after treatment with ceftazidime, antiepileptic drug and heparin without clinical recurrence. Neuromelioidosis is a rare syndrome that may present as brain abscess, encephalitis or meningoencephalitis. The authors report dural sinus thrombosis associated with septicemic melioidosis. The authors' hypothesis of venous thrombosis in the presented case is sepsis induced hypercoagulable state. Physicians should be aware of cerebral venous thrombosis in case of suspicious melioidosis with neurological involvement. Prompt treatment with intravenous heparin and antibiotic is potentially effective.

The patient was 66 year-old man with no family history of neurological diseases. At age 51, he showed initial symptom of parkinsonism, and was revealed a cerebellar atrophy by CT at age 52. He was suffered from malignant syndrome followed by renal dysfunction, which needed hemodialysis therapy. At age 54, he admitted to our hospital, when he showed parkinsonism, ataxia and dysautonomia. Neuroimaging study disclosed typical findings of multiple system atrophy (MSA), and dilatation of inferior horn of the lateral ventricle. In the next year, he lost of amburatory function, and showed low cognitive function of 5 scores in HDSR. At age 57, he was tracheostomised because of complete paralysis of the vocal cord abductor muscles. MRI study disclosed marked temporal lobe atrophy. He was complicated with bladder carcinoma, and died of multiple organ failure at age 66. The brain weight was 1,115 g. Gross neuropathological findings were temporal lobe dominant cerebral atrophy and marked pontocerebellar atrophy. Meningitis and sepsis were seen in the cerebrum, and some infarctions in the temporal and frontal lobes. Besides the typical degenerative findings of MSA, remarkable temporal lobe atrophy with enlargement of the inferior horn of lateral ventricle was observed. There were numerous number of neuron containing neuronal inclusion body (NCI) in the hippocampal cortex, dentate fascia and parahippocampal gyrus. In spite of small amount of NFT in the parahippocampal gyrus, there were no se- nile plaque, tau-positive structure except NFT, argyrophilic grain or Pick body. This case was a long-survived MSA with remarkable atrophy of the temporal lobe. The characteristic neuropathological finding was numerous numbers of neurons containing NCI in the cotices arround the inferior horn. Although frontal lobe dominant cerebral lobe atrophy is common in the long-survived MSA cases, extreme temporal lobe atrophy is rare condition. There may be a MSA subtype strongly affecting temporal lobe with numerous NCI.

The necrotizing fasciitis is a medico-surgical emergency, characterized by the rapid speard of the infection in the subcutaneous tissue, involving fascia superficialis. Peaucity of cutaneous findings early in the course of the disease makes diagnosis a challenge for physician. Pain out of proportion to clinical findings, fever and signs of systemic toxicity are the keys in identification of necrotizing fasciitis. Delayed diagnosis lead to sepsis syndrom and/or multiple organ failure and correlate with poor oucome. Radiolographs, CT-scan or MRI are main radiologic studies, but such procedures should never delay surgical intervention. Intravenous antibiotics, fluid and electrolyte management and analgesia are needed in addition to radical debridment. Clindamycin, hyperbaric oxygen therapy and intravenous immunoglobulins are discussed treatments. Only prompt recognition and immediat care warrant a lower mortality and morbidity for this life-threatening infection.

Neuropathic ulcerations and altered immune function place the diabetic patient at increased risk for polymicrobial osteomyelitis of the foot and ankle. The optimal method for evaluation and management of this difficult condition is controversial, and further studies are needed. Infected ulcers with exposed or palpable bone can be assumed to have underlying osteomyelitis. Although plain film should be ordered in each case, MRI is most often used for evaluation and surgical planning. Difficult cases, such as those associated with Charcot osteoarthropathy, may require labeled leukocyte scanning or bone biopsy to arrive at the diagnosis. A multidisciplinary team approach is best, allowing optimal treatment of all associated conditions that commonly affect patients with diabetes mellitus. Vascular evaluation and intervention are critical in the presence of vascular insufficiency or ischemia. Empiric, usually broad-spectrum antibiotics and meticulous local wound care may achieve remission of mild to moderately severe infections and should be included in all treatment regimens. Severe, infections, ischemia, or sepsis requires an aggressive surgical approach. Bone resection, correction of deformity, or amputation often are necessary and should be done with the goal of salvaging a functional foot.

Infectious muscle diseases have very different aetiologies. The viral myositides are proved by clinical and laboratory evidences in various etiologic settings (Influenza A and B, Coxsackie and HIV). The bacterial myositis was considered in the near past a tropical disease, but in our days with migration of people from South to North and the endemia of AIDS it became a problem of the "civilized" world. On the other hand, tuberculous endemia in Central-Eastern Europe, including Romania, results in quite high incidence of osteoarticular tuberculosis. In this section the authors take into consideration some clinical entities, such as psoas abscess, postanginal sepsis, beta-haemolytic streptococcus infection and that caused by Koch bacillus. Other rare musculoskeletal infections such as gas gangrene and non-clostridial anaerobic myonecrosis are also reviewed. Immune depression caused by underlying diseases, therapies, alcoholism or old age is often encountered. The parasitic aetiologies include infestations with Trichinella spiralis, Cysticercus cellulosae, Toxoplasma and Amoeba. The contribution of imagistic methods to diagnosis is emphasised. Ultrasonography associated with CT imaging are usually used, while MRI should be reserved for cases in which axial skeleton is involved. The management is based on appropriate antibiotic therapy and surgery.

Crohn's disease is a chronic, transmural inflammatory process of the gastrointestinal tract. It often affects the colon with the perianal area. The most common intestinal manifestations include external and/or internal fistulas and abscesses. Assessment of the activity of perianal fistulas in the course of Crohn's disease seems to be an important factor influencing therapeutic approach. Fistula's activity is evaluated by such methods as magnetic resonance imaging, anal ultrasound and examination under anaesthesia. Usefulness of imaging methods in the diagnosis of fistulas still remains to be defined.MRI is used to present a wide spectrum of perianal fistulazing Crohn's disease. Additionally, it is an important instrument revealing location, extent and severity of inflammation. It is also very helpful to detect clinically silent sepsis related to small, local inflammation. The most common method used in MR imaging to assess topography of a fistula's track, is Parks' classification.Clinical indications to MRI may include follow-up studies of a diagnosed disease, classification of fistulas' subtypes in the course of Crohn's disease, determination of the extent of fistulas' tracts and spread of an inflammatory process what can guide surgical procedures.

We present a patient with Posterior Reversible Encephalopathy Syndrome (PRES). A 74-year-old woman was admitted with sepsis, which originated from erysipelas on her neck the following day. She developed respiratory obstruction due to oedema, septic shock, disseminated intravascular coagulation (DIC), acute renal failure and atrial fibrillation. She responded well to treatment and improved rapidly, despite of her serious condition. When she had almost fully recovered after 15 days, her general condition worsened, and she developed confusion, blindness and pareses. MRI showed vasogenic oedema in the parietooccipital regions of the brain and in the cerebellum, consistent with PRES. PRES is a clinical and radiological diagnosis consisting of headache, confusion, cortical blindness, convulsions and sometimes pareses. MRI of the cerebrum with diffusion-weighted imaging (DWI) and Apparent Diffusion Coefficient (ADC) map are decisive to the diagnosis, and usually shows a characteristic bilateral vasogenic oedema in the parietooccipital region. This can distinguish PRES from brain infarction, which shows a cytotoxic oedema on MRI. We discuss our patient in the light of different conditions leading to PRES, possible pathophysiological factors and treatment options.

We report a case of necrotizing fasciitis of the lower limb. This medico-surgical emergency is a life-threatening invasive soft-tissue infection which primarily involves the fascia superficialis and rapidly extends along subcutaneous tissue with relative sparing of skin and underlying muscles. Clinical presentation includes fever, signs of systemic toxicity and pain out of proportion to clinical findings. Paucity of cutaneous findings early in the course of the disease makes diagnosis challenging. The confirmation of the diagnosis is often made after surgical debridement. Delay in diagnosis and/or treatment correlates with poor outcome, leading to sepsis and/or multiple organ failure. Radiologic studies including plain radiographs, CT-scan or MRI may help to diagnose necrotizing fasciitis. Prompt surgical debridement, intravenous antibiotics, fluids and electrolytes management and analgesia are mainstays of the therapy. Adjuvant treatments like clindamycin, hyperbaric oxygen therapy and intravenous immunoglobulins are discussed.
