This study confirms that medullary sponge kidney (MSK) has a good prognosis, but there is a considerable morbidity in patients with renal calcification; they suffer renal colic, ureteric obstruction, and frequently need operation. There is a high incidence of urinary infection in women. On follow-up, glomerular function is well maintained, although careful testing shows a mild depression of glomerular filtration rate in at least 40%. Proximal tubular function is normal, but abnormalities of distal tubular function are often seen: acidification defects occur in 24% and are associated with nephrocalcinosis, poor urine concentrating ability, and diminished glomerular function. Urine concentration defects occur in 73% and are probably secondary to nephrocalcinosis. Hypercalciuria was present in 19% and was not related to other defects.

Primary hyperparathyroidism is the most common cause of hypercalcemia and 80-85% of the patients have parathyroid tumors. The purpose of this retrospective review was to analyse whether differences exist between patients with parathyroid tumors treated in the 1980s and 1990s. Between 1980-1997, 253 patients underwent initial surgical neck exploration for hyperfunctioning parathyroid tumors. Renal (polyuria, nocturia, renal colic due to lithiasis), rheumatologic (bone and joint pain), neurological (fatigue, memory loss, depression) and gastrointestinal (dyspepsia, anorexia, nausea) symptoms were recorded and main biochemical parameters were measured. In all patients one or more preoperative localization procedures were carried out prior to successful parathyroidectomy, and the confirmation of imaging findings was obtained after surgery. The patients were divided in two groups. Group A: 121 (47.8%) patients who underwent surgery from 1980-1989; Group B: 132 (52.2%) patients in whom parathyroidectomy was performed from 1990-1997. There were no differences (p=NS) between the two groups in average age, preoperative serum creatinine and intact-PTH levels. Symptoms were most common in Group A, and pre-operative serum calcium levels were significantly lower in Group B. Ultrasonography (n=191) sensitivity did not improve significantly (82.8% vs 82.9%), but positive predictive value (PPV) was higher (89.8% vs 96.0%). CT-scan (n=73) sensitivity was 79.2% and 82.6%, and PPV was 95.0% and 100% in Groups A and B, respectively. 201Tl/99mTc subtraction scintigraphy (n=111, Group A) was 84.6% sensitive (PPV=92.6%) whereas 99mTc-sestamibi scanning (n=90, Group B) was 85.1% sensitive (PPV=96.1%). In conclusion, the clinical features of parathyroid tumors has changed in the nineties and increasing asymptomatic pHPT rate has been found. Although sensitivity and PPV of preoperative localization procedures has improved moderately, at present noninvasive techniques may offer excellent results and should be used in all patients with suspected parathyroid tumors.

In this paper evidence is presented that Michelangelo met the criteria for Asperger's disorder, or high-functioning autism. The evidence relates to his single-minded work routine, unusual lifestyle, limited interests, poor social and communication skills, and issues of life control. Depression and various medical conditions, including gout, renal colic and renal stones, did not stop his obsessive working habits.

Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls) matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001), anxiety trait (P = 0.005) and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62). The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002) and depression (P < 0.001) and the number of recurrent colic episodes (anxiety-state: P = 0.016 and anxiety-trait: P < 0.001). These data suggest an association between recurrent renal colic and symptoms of both anxiety and depression.

Renal colic affects up to 12% of the population. Initial management of most patients is expectant. Acute symptom management of renal colic is best accomplished with a combination of parenteral opioids and NSAIDs. The elderly patient with a kidney stone should be screened for contraindications to NSAID therapy, such as renal failure or previous peptic ulcer disease. Use of parenteral opioids is often necessary during the acute setting, and downward-adjusted doses and monitoring are necessary to prevent associated confusion and respiratory depression. Novel therapy with desmopressin may also be effective for symptom control at the initial presentation, without the adverse effects of opioids or NSAIDs. However, use of desmopressin in the elderly must be undertaken cautiously, given the potential adverse effects of this agent. Many small, distal ureteral stones are treated initially with watchful waiting for the first 2-4 weeks after presentation. The patient should have effective, non-parenteral analgesics for use at home. Included in these agents are oral or suppository NSAIDs and oral opioids. Medical expulsion therapy with alpha-adrenoceptor antagonists or calcium channel antagonists is efficacious. alpha-Adrenoceptor antagonists such as the alpha(1A/)(1)(D)-selective tamsulosin are well tolerated in the elderly and increase the rate of spontaneous stone passage by approximately 50% for small distal stones. These agents also appear to decrease the severity of renal colic. Corticosteroids and calcium channel antagonists are also effective but their use in the elderly is not recommended as first-line therapy.

This report describes the clinical and biologic data and bone density measurements in 19 adults seen in a rheumatology department, with phosphate diabetes defined by low serum phosphate levels and decreased tubular reabsorption of phosphate in the absence of known etiology. There were 14 males and 5 females with a mean age at disease onset of 36.7 years (20-68 years) and at diagnosis of 43.9 years (24-70 years). Axial pain was present in 17 patients (90%), radicular pain in 13 patients (68%), pain at night in 14 patients (74%), fatigue in 7 patients (37%), myalgia in 6 patients (32%), fracture in 6 patients (32%), renal colic in 4 patients (21%) and depression 10 patients (53%). Mean serum phosphorus was 2.25 mg/dL (1.08-2.76); maximum tubular reabsorption of phosphate/glomerular filtration rate was 0.58 (0.4-0.76) (n > 0.77). Calcium/creatinine > 0.48 was seen in 9 patients (47%), indicating an associated hypercalciuria. Serum calcium, sodium, magnesium, creatinine, cortisol, T3, T4, thyroid-stimulating hormone (TSH), 25 and 1,25 OH2 vitamin D3 were normal. Glucose and amino acid were absent from urine. Bone mineral density at L2-L4 level (Z-score) was -2.13 (-0.9 to -4.25), and at the femoral neck was -1.34(-1.5 to -3.2). Bone biopsy in 5 patients showed osteoporosis with minor osteoid deposition.Idiopathic phosphorus diabetes (IPD) is a rheumatic disease with chronic axial pain at night, radiculitis-like symptoms, fatigue and depression. In half of the patients, IPD is associated with hypercalciuria. Bone mineral density at L2-L4 and femoral neck level is low. Bone biopsies show osteoporosis. Chronic pain, fatigue and depression resulting from IPD may be improved by treatment with oral calcitriol and phosphorus. There might be a delay in improvement of a few months, even if the blood phosphate level is normalized. A 3% increase in bone mineral density could be measured at 6-month intervals when blood phosphate was maintained. This disease is often misdiagnosed when the maximal reabsorption rate of phosphorus is not calculated.

Introduction and aim Pain is a frequent symptom in emergency patients and opioids are commonly used to treat it at emergency departments and at pre-hospital settings. The aim of this systematic review is to examine the efficacy and safety of parenteral opioids used for acute pain in emergency medicine. Method Qualitative review of randomized controlled trials (RCTs) on parenteral opioids for acute pain in adult emergency patients. Main outcome measures were: type and dose of the opioid, analgesic efficacy as compared to either placebo or another opioid and adverse effects. Results Twenty double-blind RCTs with results on 2322 patients were included. Seven studies were placebo controlled. Majority of studies were performed in the emergency department. Only five studies were in prehospital setting. Prehospital studies Four studies were on mainly trauma-related pain, one ischemic chest pain. One study compared two different doses of morphine in mainly trauma pain showing faster analgesia with the larger dose but no difference at 30 min postdrug. Three other studies on the same pain model showed equal analgesic effects with morphine and other opioids. Alfentanil was more effective than morphine in ischemic chest pain. Emergency department studies Pain models used were acute abdominal pain seven, renal colic four, mixed (mainly abdominal pain) three and trauma pain one study. Five studies compared morphine to placebo in acute abdominal pain and in all studies morphine was more effective than placebo. In four out of five studies on acute abdominal pain morphine did not change diagnostic accuracy, clinical or radiological findings. Most commonly used morphine dose in the emergency department was 0.1 mg/kg (five studies). Other opioids showed analgesic effect comparable to morphine. Adverse effects Recording and reporting of adverse effects was very variable. Vital signs were recorded in 15 of the 20 studies (including all prehospital studies). Incidence of adverse effects in the opioid groups was 5-38% of the patients in the prehospital setting and 4-46% of the patients in the emergency department. Nausea or vomiting was reported in 11-25% of the patients given opioids. Study drug was discontinued because of adverse effects five patients (one placebo, two sufentanil, two morphine). Eight studies commented on administration of naloxone for reversal of opioid effects. One patient out of 1266 was given naloxone for drowsiness. Ventilatory depression defined by variable criteria occurred in occurred in 7 out of 756 emergency department patients. Conclusion Evidence for selection of optimal opioid and dose is scarce. Opioids, especially morphine, are effective in relieving acute pain also in emergency medicine patients. Studies so far are small and reporting of adverse effects is very variable. Therefore the safety of different opioids and doses remains to be studied. Also the optimal titration regimens need to be evaluated in future studies. The prevention and treatment of opioid-induced nausea and vomiting is an important clinical consideration that requires further clinical and scientific attention in this patient group.
