An 11-year-old girl presented with headache of 3 months' duration. There was bilateral disc edema. The cerebrospinal fluid pressure was 50 cm of water with normal cerebrospinal fluid cytology and biochemistry. She developed severe headache (different and disabling), dizziness, vomiting, and backache on sitting up 6 hours after lumbar puncture, and lying supine relieved all of her symptoms. Intravenous fluids, analgesics, and complete bed rest did not relieve her symptoms over the next 72 hours. She was completely relieved of her symptoms on receiving two tablets of Caffergot containing 200 mg of caffeine and 2 mg of ergotamine 72 hours after lumbar puncture. The symptoms recurred 48 hours later, and a repeat dose of Caffergot was required. Magnetic resonance imaging (MRI) done 96 hours after lumbar puncture revealed the entire dura overlying the brain, including the posterior fossa, showing intense enhancement on contrast injection with leak at the lumbar puncture site. Oral caffeine (coffee, three times a day) was advised over 1 week. The patient remained asymptomatic, and a repeat MRI scan after 10 days showed complete clearing of the cerebrospinal fluid leak with no dural enhancement. The syndrome of cerebrospinal fluid hypovolemia following lumbar puncture is reported in a girl with idiopathic intracranial hypertension.

An elderly lady developed an epidural hematoma following combined spinal-epidural anesthesia with a local anesthetic-opioid mixture for a vaginal hysterectomy. This occurred in association with the use of prophylactic subcutaneously administered unfractionated heparin. She had diabetes, hypertension and had previously undergone coronary artery bypass surgery and right carotid endarterectomy. Warfarin and aspirin were discontinued 2 weeks before the surgery. Postoperatively, an atypical presentation of backache, bilateral sensory loss and left lower limb monoplegia ensued. The initial clinical impression was of a cerebrovascular accident. Magnetic resonance imaging, however, revealed an extensive epidural hematoma that necessitated decompression laminectomy. Progression to paraparesis occurred but the patient gradually regained much of her functionality over the next 2 years.

The level of fatness of a child at which morbidity acutely and/or later in life increases is determined on an acturial basis. Direct measurements of body fat content, e.g. hydrodensitometry, bioimpedance, or DEXA, are useful tools in scientific studies. However, body mass index (BMI) is easy to calculate and is generally accepted now to be used to define obesity in children and adolescents clinically. An increased risk of death from cardiovascular disease in adults has been found in subjects whose BMI had been greater than the 75th percentile as adolescents. Childhood obesity seems to substantially increase the risk of subsequent morbidity whether or not obesity persists into adulthood. The genetic basis of childhood obesity has been elucidated to some extent through the discovery of leptin, the ob gene product, and the increasing knowledge on the role of neuropeptides such as POMC, neuropeptide Y (NPY) and the melanocyte concentrating hormone receptors (for example, MC4R). Environmental/exogenous factors largely contribute to the development of a high degree of body fatness early in life. Twin studies suggest that approximately 50% of the tendency toward obesity is inherited. There are numerous disorders including a number of endocrine disorders (Cushing's syndrome, hypothyroidism, etc.) and genetic syndromes (Prader-Labhard-Willi syndrome, Bardet Biedl syndrome, etc.) that can present with obesity. A simple diagnostic algorithm allows for the differentiation between primary or secondary obesity. Among the most common sequelae of primary childhood obesity are hypertension, dyslipidemia, back pain and psychosocial problems. Therapeutic strategies include psychological and family therapy, lifestyle/behaviour modification and nutrition education. The role of regular exercise and exercise programmes is emphasized. Surgical procedures and drugs used in adult obesity are still not generally recommended in children and adolescents with obesity. As obesity is the most common chronic disorder in industrialized societies, its impact on individual lives as well as on health economics has to be recognized more widely. This review is aimed towards defining the clinical problem of childhood obesity on the basis of current knowledge and towards outlining future research areas in the field of energy homoesostasis and food intake in relation to child health. Finally, one should aim to increase public awareness of the ever increasing health burden and economic dimension of the childhood obesity epidemic that is present around the globe.

Existing therapies for major depressive disorder (MDD) have either limited efficacy and/or poor tolerability. The present study examined the effects of duloxetine, a potent and balanced dual reuptake inhibitor of serotonin (5-HT) and norepinephrine (NE), in patients with MDD. Adult patients (N = 267) with MDD were randomly assigned to receive duloxetine (60 mg/day) or placebo in this 9-week, multi-center, double-blind, parallel-group clinical trial. Efficacy was evaluated using the 17-item Hamilton Depression Rating Scale (HAMD(17)), Visual Analog Scales (VAS) for pain, Clinical Global Impression of Severity (CGI-S), Patient's Global Impression of Improvement (PGI-I), and Quality of Life in Depression Scale (QLDS). Safety was evaluated by assessing discontinuation rates, adverse event rates, vital signs, and laboratory tests. Duloxetine (60 mg QD) significantly reduced the HAMD(17) total score compared with placebo at the end of 9-week therapy. Estimated probabilities of response and remission were 65 and 43%, respectively, for duloxetine compared with 42 and 28% for placebo. Duloxetine also reduced overall pain, back pain, shoulder pain and time in pain while awake significantly more than placebo. Global measures of improvement, including PGI-I and QLDS, were significantly improved by duloxetine compared with placebo. Discontinuations due to adverse events were more frequent for duloxetine-treated patients (12.5%) than for placebo-treated patients (4.3%). Nausea, dry mouth, dizziness, and constipation were more frequent for duloxetine than placebo. There was no significant incidence of hypertension, nor any other safety issues. Duloxetine 60 mg administered once daily appears to be a safe and effective treatment for MDD.

We report a case of DeBakey IIIb type dissecting aneurysm with adrenal myelo-lipoma in a 50-year-old woman. The patient was referred to our hospital for severe back pain with severe hypertension. The chest computed tomography (CT) scans and aortography showed the DeBakey IIIb type dissecting aneurysm. And the round-shaped masses on her both side adrenal glands were detected by abdominal CT scans. First, the thoracic aneurysm was replaced with a 26 mm woven dacron graft under cardiopulmonary bypass. Six months later a right adrenal tumor was removed under a postero lateral approach. Her postoperative course was uneventful. And her blood pressure control was good with no antihypertensive drug. Pathological findings for the resected tumor was diagnosed as myelolipoma. To our knowledge, a dissecting aneurysm with adrenal myelolipoma has not been previously reported.

The case of a 27-year-old Japanese woman with type A acute aortic dissection who had been diagnosed with systemic lupus erythematosus (SLE) is presented. The patient also had aortic regurgitation due to non-infective endocarditis and systemic hypertension, and had been maintained on steroid therapy for 15 years. Her twin sister was also diagnosed with SLE. The patient was admitted to emergency due to severe back pain. A chest x-ray showed enlargement of the upper mediastinum. Echocardiography revealed a thickened and deformed aortic valve with aortic regurgitation and dissection of the ascending aorta, but pericardial effusion was not found. Computed tomography demonstrated aortic dissection extending from the ascending aorta to the abdominal aorta. Graft replacement of the ascending aorta and proximal aortic arch was performed under hypothermic circulatory arrest with retrograde cerebral perfusion. The patient recovered uneventfully. Aortic dissection complicated with SLE is extremely rare, and this is only the 15th case reported in the English or Japanese literature.

Endovascular techniques with coil embolization have been used in certain visceral aneurysm cases, often resulting in sacrifice of the involved visceral vessel and end-organ thrombosis. We describe two cases in which stent grafts were used to treat these aneurysms, allowing preservation of visceral artery and end-organ flow while completely excluding the aneurysm. Case 1 was a 50-year-old morbidly obese woman with a history of multiple abdominal operations for renal cell carcinoma who was found to have a large splenic artery aneurysm. A 12-mm x 50-mm Wallgraft endoprosthesis (Boston Scientific, Watertown, Mass) was placed across the aneurysm from a femoral approach. The aneurysm was completely excluded, and splenic artery flow was preserved. A subsequent computed tomographic scan showed complete aneurysm exclusion and preserved flow to the spleen. Case 2 was a 73-year-old man with hypertension with back pain who was found with computed tomographic scan to have an 8-cm hepatic artery aneurysm. Arteriography showed a large saccular aneurysm arising from the mid portion of the common hepatic artery. Two 5-mm x 26-mm Jostent stent grafts (Jomed, Alpharetta, Ga) were placed across the aneurysm neck, completely excluding the aneurysm and preserving hepatic artery flow. The patient became pain free, and subsequent duplex ultrasound scan showed a thrombosed aneurysm with normal hepatic artery flow. Stent graft techniques show early promise as a safe and effective treatment of visceral artery aneurysms in selected patients at high risk. Endografts, unlike coil embolization, exclude the aneurysm and preserve end organ perfusion. Determining the durability of this type of therapy will require further study.

An arteriovenous malformation (AVM) is an anomaly of capillary development that results in a direct connection between branches of an artery and veins, with no intervening capillary network. A definite diagnosis of AVM is usually made with angiography. We report the case of a posterior mediastinal AVM found on routine sonography in a 64-year-old woman with neglected hypertension and severe back pain. Color Doppler imaging showed 2 adjoined vascular structures without a typical mosaic-like flow pattern, and spectral Doppler analysis showed low-resistance flow and arteriovenous shunting in 2 adjoined vascular structures. The diagnosis was subsequently confirmed by angiography. Because disastrous bleeding could result if needle biopsy were performed inadvertently in the case of a suspected mediastinal AVM, we suggest that color Doppler sonography be attempted if there is an adequate acoustic window.

The comorbidities of diabetes mellitus were evaluated in an Asian American population with podiatric symptoms living in southern California. The three most common nonpedal complaints in men were blurred vision (73.6%), hypertension (64.1%), and erectile dysfunction (52.3%) and in women were blurred vision (84.5%), incontinence (71.5%), and low-back pain with radiculopathy-like symptoms (56.5%). The most significant finding was that only 3.2% of all patients had any previous knowledge or understanding of the risks of foot infection, ulceration, and amputation secondary to diabetes mellitus. The prevalence of diabetes mellitus in ethnic populations once considered practically exempt continues to rise steadily, and Asians living in the United States are becoming casualties of diabetes mellitus and its complications.

The development of COX2 inhibitors with improved biochemical selectivity (such as etoricoxib and valdecoxib) over that of commercially available coxibs has been driven by the potential advantage of safety using higher coxib doses for increased efficacy. Etoricoxib has been approved in the UK as a once-daily medicine for symptomatic relief in the treatment of osteoarthritis (OA), rheumatoid arthritis (RA) and acute gouty arthritis. It is currently approved with additional indications (i.e., for relief of acute pain associated with dental surgery, for primary dysmenorrhoea and for chronic musculo-skeletal pain, including chronic lower-back pain) in Mexico, Brazil and Peru. Etoricoxib has an in vitro COX1/COX2 IC(50) ratio of 344, the highest of any coxib. The administration of therapeutic doses of etoricoxib to healthy subjects does not affect COX1 activity in circulating platelets and gastric biopsies. The profound inhibition of monocyte COX2 activity at 24 h after dosing, as predicted by a pharmacological half-life of approximately 22 h, supports a once-daily dosing regimen of etoricoxib. In randomised, well-controlled clinical trials, etoricoxib has been shown to have a comparable clinical efficacy with traditional NSAIDs. Combined analysis of efficacy trials with etoricoxib versus non-selective NSAIDs has shown that the drug halves both investigator-reported upper gastrointestinal perforation, ulcers and bleeds (PUBs) and confirmed PUBs, and reduces the need for gastroprotective agents and gastrointestinal comedications by approximately 40%. The risk of lower extremity oedema and hypertension adverse experiences with etoricoxib was low and generally similar to comparator NSAIDs in a combined analysis of eight Phase III studies in OA, RA, chronic low-back pain and surveillance endoscopy. Large, randomised clinical trials have been planned to confirm the renal, gastrointestinal and cardiovascular safety of etoricoxib.
