    Renal angiomyolipoma is a rare benign tumour, often associated with congenital diseases especially de Bourneville's tuberous sclerosis. Bilateral angiomyolipoma is exceptional. The authors report a case of bilateral renal angiomyolipoma in a 33-year-old patient presenting with haemorrhagic shock. In the light of this case and a review of the literature, the authors discuss the diagnostic and therapeutic aspects of this disease.

    Renal Lymphangiectasia (RLM) is very rare benign lymphatic malformation. It can be misdiagnosed for other cystic renal masses, most commonly polycystic kidneys. Though incidentally found in most cases, it may be the cause for hypertension and renal failure in undiagnosed patients. Here, we report a case of an adult asymptomatic male with bilateral RLM which was detected as an incidental finding on ultrasound. Confirmation by CT-scan and laboratory diagnosis of aspirated fluid was done, and patient was managed conservatively.

  3. Traumatic bilateral renal infarction.

    PubMed

    Peterson, N E

    1989-02-01

    Published examples of unilateral and bilateral renal artery thrombosis attest to their usual subjection to nephrectomy at diagnosis or soon thereafter, eliminating the opportunity for spontaneous improvement which would enlighten the issue of how often late recovery may occur, and under what circumstances. Seven cases of renal artery thrombosis and five patients with renal artery embolization extracted from the literature have included documentation of patchy histologic viability within otherwise total infarction. Conversely, 47 reports of renal artery thrombosis culminating in nephrectomy or examined post mortem include no reference to any of these histologic features. Presumptions are speculative regarding whether these features were absent, overlooked, or unexamined. Their incidence cannot be estimated--only the possibility of recoverable renal function in an unknown number of involved patients. It may be presumed that the majority of kidneys exposed to sustained arterial interruption will undergo irreversible infarction, with an undefined small subgroup later developing renal hypertension. An unknown number, however, may fortuitously possess arterial collateralization competent to support sufficient numbers of viable nephrons to sustain adequate renal function. It is further speculated that shared pathophysiologic features establish the opportunity for misdiagnosis of renal cortical necrosis, which carries a documented potential for spontaneous recovery. Impulsive bilateral nephrectomy may therefore be unjustified, particularly in consideration of the minimal potential hazards of nonremoval. In the event of convalescent problems of renal origin, delayed nephrectomy remains an option. The requirement for interval hemodialysis is further influenced by the advantages accruing from retention of the native kidneys relative to calcium metabolism and blood product replacement. A final consideration relates to the advisability of secondary revascularization of

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    Patients with metachronous bilateral renal cell carcinoma pose a significant challenge given the high mortality of renal cell carcinoma and the poor quality of life should dialysis become necessary. In addition, patients may be subject to morbidity due to potential multiple treatments of the multifocal renal tumors. We present the case of a 71-year-old woman with multifocal, bilateral clear cell carcinoma who maintained a minimal change in serum creatinine after undergoing unilateral radical nephrectomy, subsequent percutaneous radiofrequency ablation, percutaneous cryoablation, laparoscopic cryoablation, and open partial nephrectomy for recurrent renal cell carcinoma in a solitary kidney.

    Cherubism is a self-limiting non-neoplastic autosomal dominant fibro-osseous syndrome of the jaws. It is occasionally manifested before the age of two years. It occurs in children and more often in boys. It is characterized by notable clinical bilateral swelling of the cheeks due to a bony enlargement of the jaws that impart a characteristic ‘cherubic’ look. Regression occurs in the course of puberty leaving a few facial deformities and malocclusion. Cherubism might occur in solitary cases or in several members of the family, often in many generations. The reported case is an example of solitary sporadic occurrence within a family, which is a rarely documented condition in the literature. PMID:27588230

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    Renal artery thrombosis is a rare, but serious and often under-diagnosed condition. We report a case of bilateral renal artery thrombosis secondary to acute necrotizing pancreatitis. A 66-year-old female presented with abdominal pain and acute kidney injury (AKI). A renal biopsy showed organized intraluminal thrombi and a computer tomography scan of the abdomen showed bilateral renal artery thrombosis. Emergent laprotomy showed necrosed pancreas. Doppler studies showed deep vein thrombosis of the lower extremities and internal jugular vein thrombosis. Workup for hypercoagulability was unremarkable. The final diagnosis was AKI secondary to bilateral renal artery thrombosis probably due to hypercoagulability of acute necrotizing pancreatitis. PMID:26064514

    Pyelonephritis is defined as an inflammation of the kidney and renal pelvis. The diagnosis is usually clinical. Acute multifocal bacterial nephritis is a rare form of pyelonephritis that is more severe and sepsis is more common. We report a patient who presented with fever and right-sided abdominal pain associated with right flank tenderness, suggesting right acute pyelonephritis. Bilateral multifocal pyelonephritis was diagnosed on ultrasonography, radionuclide renal scintigraphy and computed tomography. However, owing to non-resolution of symptoms, a biopsy was performed, which showed bilateral papillary renal cell carcinoma (PRCC). PRCC is known to exhibit multicentricity. To our knowledge, a case of bilateral multicentric PRCC masquerading as bilateral multifocal pyelonephritis has not been reported in the English literature. This case highlights the need to be vigilant while treating patients with focal lesions of the kidney as an inflammatory condition lest a malignancy should be missed.

    A 21 year old male was discovered to be severely hypertensive. He was found to have bilateral adrenal phaeochromocytomas and a single renal artery stenosis. More than 40 cases of coexisting renal artery stenosis and phaeochromocytomas have been reported. The aetiology of renal artery stenosis in association with phaeochromocytoma maybe multifactorial and the radiographic appearances are not always clear-cut. Renin levels in this patient were elevated prior to the removal of the phaeochromocytomas but the renal vein renin ratio did not suggest that the renal artery stenosis contributed significantly to his hypertension. The patient's hypertension resolved following successful removal of the phaeochromocytomas despite persistence of the renal artery stenosis. Thus, though renin levels may be misleading in these cases, renal vein renin ratios may still be helpful in deciding on patient management. Images Figure 1 Figure 2 PMID:2694147

    An 81-year-old female presented with abdominal discomfort. Computed tomography scan showed a 26 x 22 mm tumor in the left kidney and 43 x 37 mm tumor in the right kidney. Clinical diagnosis was bilateral renal cell carcinoma, left; cT1a, right; cT1bN0M0. We planned primary unilateral partial nephrectomy, followed by secondary contralateral radical nephrectomy. Left partial nephrectomy was performed and 4 months later, laparoscopic right renal nephrectomy was performed without serious postoperative renal dysfunction. Pathological diagnosis of both tumors was chromophobe renal carcinoma. The patient has been doing well without any evidence of recurrence or metastasis.

    The authors report an uncommon case of bilateral synchronous adrenal gland metastases from left renal cell carcinoma. The diagnosis was established by abdominal ultrasound and computed tomography. The surgical approach initially consisted of left radical nephrectomy and ipsilateral adrenalectomy. Histologically, the tumor of the left adrenal gland was identical to the left renal cell carcinoma. Subsequent contralateral adrenalectomy showed an adrenal metastasis identical to the left renal cell carcinoma. Patient follow-up was good with no recurrence of the disease after one year. This is an uncommon case for renal cancer. The treatment and prognosis are discussed.

    A 2-year-old male presented to hospital with a 5-day history of vomiting and pyrexia. He was initially treated with non-steroidal medication as an anti-pyretic. Initial investigations demonstrated a raised urea and creatinine and he was treated with intravenous fluids. Within 24 h he became anuric with progressive renal insufficiency. Ultrasound scan demonstrated minimal bilateral hydronephrosis with debris in the lower pole calyces. The bladder was empty. Cystoscopy and retrograde contrast imaging revealed bilateral ureteric obstruction. Double J stents were inserted and his renal function returned to normal within 4 days. We believe the aetiology to be renal papillary necrosis and bilateral ureteric obstruction secondary to the administration of ibuprofen in association with dehydration.

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith–Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB. PMID:25871299

    Renal hypodysplasia (RHD) is a congenital disorder, characterized by an abnormally developed kidney. Mutations in genes such as PAX2, HNF1-beta, TCF2, EYA1, that encode factors critical in early renal development, are being found. RHD is the leading cause of chronic renal failure in childhood, with or without associated urologic abnormalities such as vesicoureteric reflux and urinary tract obstruction. Antenatal detection has improved understanding of this disorder, resulting in enhanced outcomes through earlier intervention, including peritoneal dialysis. Management requires a multidisciplinary team approach that commences prior to the birth of the child.

    Endometriosis is a common disease but ureteral involvement is relatively rare. Ureteric endometriosis is mostly unilateral. Endometriotic ureteral obstruction is a serious event commonly diagnosed late and therefore associated with a major risk of hydronephrotic renal atrophy. We present the cyclical acute renal failure associated with menstruation in a patient who developed severe bilateral ureteral obstruction due to endometriosis. Physicians should be aware of this uncommon but serious manifestation of endometriosis, especially if the clinical presentation is cyclical acute renal dysfunction in a premenopausal woman.

    Background The testicular arteries normally arise from the abdominal aorta. There are reports about the variant origin of these arteries. Accessory renal arteries are also a common finding but their providing origin to testicular arteries is an important observation. The variations described here are unique and provide significant information to surgeons dissecting the abdominal cavity. Case presentation During routine dissection classes of abdominal region of a 60-year-old male cadaver, we observed bilateral variant testicular arteries and double renal arteries. Conclusion Awareness of variations of the testicular arteries such as those presented here becomes important during surgical procedures like varicocele and undescended testes. PMID:19187540

    Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vascular structures at the hilum of the kidney in terms of their pattern of arrangement and division. The present paper describes a bilateral anomalous arrangement of the structures at the renal hilum as well as their peculiar branching pattern which is of clinical and surgical relevance. Multiple branching of the renal vessels was observed in both kidneys due to which the hila were congested. The right renal artery immediately after its origin divided into 2 branches. The upper branch represented an aberrant artery whereas the lower branch gave 5 divisions. The left renal artery also divided into 2 branches much before the hilum as anterior and posterior divisions. The anterior branch took an arched course and gave 6 branches. The posterior branch gave 3 terminal branches before entering the renal substance. In addition to anomalous hilar structures, normal architecture of both kidneys was altered and the hilum of the left kidney was found on its anterior surface. PMID:23346454

Renal Doppler duplex sonography revealed large solid bilateral neoformation. Total-body computed tomography confirmed the presence of bilateral kidney lesions and also showed the presence of concomitant gross dyscariocinetic lesion of left hemotorax. The patient underwent bilateral native nephrectomy and the histological diagnosis was renal cell carcinoma. Subsequent left upper lobectomy revealed necrotic keratinizing squamous cell carcinoma. Then, the patients was switched tacrolimus to everolimus treatment and mycophenolate mofetil was reduced.

    The bilateral primary renal lymphoma (PRL) is a rare disease with a high mortality rate (75% within the first year). We report the case of a fifty-three years old women observed in January 2011 for renal colic. Ultrasonography showed hypoechoic lobular formations in the kidney. Blood tests showed: creatinine 1.8 mg/dl, urea 75 mg/dl , Creatinine Clerance 35 ml/m, hemoglobinemia 11 g/dl, with blood cells 8.500/mcL, Albumin 2.8 g/dl, Beta -2 micro - 27.3/mL. Proteinuria was 0.3 g/24 hours. The CT scan showed kidneys with larger dimensions and multiple hypodense areas infiltrating the renal parenchyma with contrast-enhanced low in which kidneys had lesions similar to "leopard skin". The CT scan showed no enlarged lymph nodes. Renal biopsy showed: renal parenchyma largely occupied by infiltration of lymphoid elements, small and medium-sized, densely packed with compression of the tubular structures . Immunofluorescence for immunoglobulin (Ig) G, IgA, IgM, C3, C4, C1q, fibrinogen, kappa and lambda were negative. The bone marrow biopsy excluded lymphomatous infiltration. The histological diagnosis was "non-Hodgkin's B-cell lymphoma"; the clinical diagnosis was LRBP. The patient was treated by 6 cycles of R-CHOP-21 protocol (rituximab - endoxan, adriblastina , vincristine, prendnisone), the latter of which practiced in August 2011. The pt is currently in follow-up hematology and nephrology . The first TAC control , in October 2011, showed a complete regression of the lesions infiltrating . This finding was confirmed by two other CT scan performed in February and October 2012. The last blood tests of February 2013 showed : creatinine 1.1 mg / dl , Urea 40 mg/dl, proteinuria absent. Currently, the pt is asymptomatic and is being treated by low dose of ACE inhibitor. The bilateral PRL is considered a severe disease with one-year mortality of 75% . The successful outcome of the case described can be attributed to haematological therapy and to the early diagnosis.

    Cloacal dysgenesis sequence (CDS) is a rare congenital anomaly. It is characterised by a smooth perineum with absence of anal and genitourinary orifices, with reported incidence of 1:50,000-250,000 births. Association with bilateral renal agenesis is still rarer and resultant severe oligohydramnios is associated with pulmonary hypoplasia. Only a few cases of CDS with bilateral renal agenesis have been reported in the English language literature, with associated pulmonary hypoplasia as a default phenomenon. We report a case of CDS and bilateral renal agenesis without associated pulmonary hypoplasia in a twin pregnancy, which, to the best of our knowledge, is the second reported case of this amalgamation.

    We describe the clinical course of a 5-year-old girl with severe arterial hypertension that was uncontrollable with antihypertensive medication. Renal angiography revealed bilateral renal artery stenoses. Because percutaneous transluminal renal angioplasty (PTRA) failed to dilate the stenotic lesions, a renal artery bypass grafting in both renal arteries was performed. The patient remained normotensive for 7 months, and after that the arterial pressure increased again. Digital subtraction angiography demonstrated stenosis at the peripheral and central anastomosis of the vein graft that was used for revascularization of the left kidney. PTRA was decided on and successful patency was achieved. The patient has now been normotensive for a period of 5 years.

    We herein report a rare case of acute bilateral renal and splenic infarctions occurring during chemotherapy for lung cancer. A 60-year-old man presented with acute and intensive upper abdominal and back pain during chemotherapy with cisplatin and etoposide for lung cancer. Contrast-enhanced computed tomography (CT) revealed bilateral renal and splenic infarctions. After the administration of unfractionated heparin his pain was relieved with a clearance of the infarctions in the CT findings and a recovery of renal dysfunction. Enhanced coagulation by lung cancer and arterial ischemia by chemotherapy may therefore contribute to the development of these infarctions. PMID:27980265

    Abstract Background: Zygomycoses are uncommon, frequently fatal diseases caused by fungi of the class Zygomycetes. The majority of human cases are caused by Mucorales (genus—rhizopus, mucor, and absidia) fungi. Renal involvement is uncommon and urine microscopy, pottasium hydroxide mount, and fungal cultures are frequently negative. Case Presentation: A twenty-one-year-old young unmarried lady presented to our emergency department with bilateral flank pain, fever, nausea, and decreased urine output of one-month duration. She was found to have azotemia with sepsis with bilateral hydronephrosis with a left renal pelvic obstructing stone. Even after nephrostomy drainage and broad spectrum antibiotics, her condition worsened. She developed disseminated fungal infection, and timely systemic antifungal followed by bilateral nephroscopic clearance saved the patient. Conclusion: Although renal fungal infections are uncommon, a high index of suspicion and early antifungal and surgical intervention can give favorable outcomes. PMID:27704055

    A 3.5-year-old male neutered cat was presented for investigation of renomegaly appreciated during a routine physical examination. Marked renomegaly due to bilateral hydronephrosis was detected and further testing identified International Renal Interest Society stage 2, non-hypertensive, non-proteinuric chronic kidney disease. Ten months later the cat was evaluated for acute lethargy; severe azotemia with oliguria was documented. Medical therapy failed to result in clinical improvement and the cat was euthanased. Necropsy revealed bilateral marked hydronephrosis secondary to a tortuous proximal ureter consistent with proximal ureteropelvic junction stenosis. This is the first report of this disorder leading to progressive renal failure in a cat.

    2017-01-24

    A 9-year-old sterilised female domestic short-hair cat was referred with a history of vomiting and anorexia of 3 months' duration. Biochemistry, full-blood counts, thoracic radiographs, feline pancreatic-specific lipase, abdominal ultrasonography and feline immunodeficiency virus/feline leukaemia virus (FIV/FeLV) SNAP tests had been performed. Mild hypochloraemia and moderate hypokalaemia were evident on initial presentation. Abdominal ultrasonography initially revealed unilateral renal nodules on the left side. These were subjected to fine-needle aspiration and cytological evaluation. A neuroendocrine tumour was suspected, and biopsies via midline coeliotomy were taken to confirm the diagnosis. Initial histopathology diagnosed primary renal carcinomas or neuroendocrine neoplasia; however, the definitive diagnosis became renal paragangliomas after immunohistochemistry and transmission electron microscopy were performed. The cat was regularly monitored with serum biochemistry parameters, blood pressure determinations, thoracic radiographs and subsequent abdominal ultrasonography. Biochemistry, radiography and blood pressures remained normal over a 24-week follow-up period, while subsequent ultrasonography revealed tumour progression in both number and size in both kidneys. Primary neuroendocrine tumours of the kidney are frequently incorrectly diagnosed as other renal tumours such as renal cell carcinoma, mesonephric tumours or undifferentiated carcinomas. This case report highlights the importance of additional testing, including immunohistochemistry and transmission electron microscopy, to obtain a definitive diagnosis of paragangliomas.

    Abstract Background: Obstructing ureteral stones are a rare cause of anuria, which is typically from prerenal or renal etiologies. Classically, obstructive stones cause moderate to severe renal colic. Urolithiasis is rarely considered during evaluation of painless anuria. Case Presentation: We present an unusual case of a 73-year-old Caucasian female who presented with anuria and was found to have large bilateral obstructing ureteral stones in the absence of renal colic. Conclusion: Given that patients with obstructive anuria can be asymptomatic, urolithiasis should be considered in all patients presenting with anuria. PMID:27579429

    Renal abscesses are infrequently encountered in children. We describe a girl diagnosed with bilateral renal abscess. Although ultrasonography and computerised tomography are used to establish the diagnosis, in our case magnetic resonance imaging proved to be a useful additional diagnostic method. Using percutaneous aspiration, we were able to establish the correct diagnosis and identify the causative micro-organism. The patient was successfully treated with a combined intravenous and oral course of antibiotics. In conclusion, renal abscesses can occur in children without a history of reflux or urinary tract infection; this should be kept in mind when evaluating a child with fever. In addition, full recovery can be achieved solely with antibiotics.

    A 51-year-old man with an 8-year history of hypertension (170/115 mmHg with two drugs) and altered renal function (5.6 mg/dl serum creatinine, 101 mg/dl BUN) was referred to our Department to evaluate the renal arteries and rule out renovascular hypertension. Doppler ultrasound and magnetic resonance angiography revealed significant bilateral renal artery stenosis and the presence of bilateral renal artery aneurysms. A self-expandable polytetrafluoroethylene (PTFE)-covered nitinol stent-graft was deployed in each renal artery to treat the stenoses and to exclude the aneurysm. Postprocedural digital subtraction angiography confirmed the resolution of the renal artery stenoses and the complete exclusion of the aneurysms. At the 6 month follow-up, color Doppler confirmed normal patency of the renal arteries with complete exclusion of the aneurysms and significant reduction of the blood pressure (130/85 mmHg with one drug) and serum creatinine levels (2.1 mg/dl)

    Renal cell cancer rarely metastasizes to the thyroid gland, and it has been reported to present as a solitary mass. We present a case of diffuse thyroid cancer metastases from renal cell cancer. Bilateral internal jugular vein tumor thrombi were also present. To the best of our knowledge, this is the first description of diffuse thyroid metastases from renal cell cancer in the English literature. Renal cell cancer metastases should be considered in the differential of thyroid imaging abnormalities arising in the setting of known renal cell carcinoma, particularly late in the course of disease. This is frequently associated with internal jugular vein thrombi, which should be evaluated with an abnormal thyroid. Thyroglobulin levels are usually normal in such patients.

She had positive antinuclear antibodies (ANA) and double-stranded deoxyribonucleic acid (dsDNA) antibodies. The lupus anticoagulant test (LAC) and cardiolipins antibodies (aCL) were positive. She was diagnosed as having a Systemic Lupus Erythematosus-like illness (SLE-like) with 'secondary' antiphospholipid syndrome (APS). Renal spiral computed tomography (CT) with intravenous (IV) contrast showed bilateral renal artery stenosis. Anticoagulation with acenocumarol was started. She became normotensive without antihypertensive drugs five months later. A follow-up renal spiral CT showed complete recanalization of both renal arteries, making thrombosis the more likely culprit pathology in the stenosis. After two years follow up the patient is normotensive. She remains on acenocumarol.

    BACKGROUND: Acute renal failure (ARF) due to obstructive uropathy is a urological emergency. The standard radiological investigations in the emergency setting include X-ray, ultrasonography and computed tomography. But occasionally the cause of obstruction may be elusive. METHODS: We present a case of obstructive uropathy due to bilateral stones presenting as acute renal failure. The patient underwent successful shock wave lithotripsy (SWL) for dissolution of calculi. RESULTS: The patient was successfully treated, and reported asymptomatic in a follow-up. CONCLUSION: Close collaboration between nephrological, urological, and radiological services is required.

    Von Hipple-Lindau (VHL) disease is a rare familial cancer syndrome that is dominantly inherited and pre-disposes affected individuals to developing various tumors, including hemangioblastoma of the retina and central nervous system, and multicentric renal cell carcinoma. We report two cases of VHL disease with bilateral renal cell carcinoma. Case 1: A 53-year-old woman was referred to our hospital because of bilateral kidney tumor incidentally found. We performed left laparoscopic radical nephrectomy and laparoscopic nephrectomy, ex vivo excision and reconstruction, and autotransplantation for the right kidney. Case 2: A 43-year-old woman was referred to our hospital because of left kidney tumor incidentally found. Because the suspectious lesion in the right kidney was very small, we decided to follow it up with no treatment. We performed laparoscopic nephrectomy, ex vivo excision and reconstruction, and autotransplantation for left kidney.

    This study analyzed the results of bilateral nephrectomy in 14 patients with end-stage renal disease (ESRD) and chronic active pyelonephritis. Seven patients had urosepsis, and 10 patients had a purulent form of pyelonephritis, which was one-sided in 7 of them. In the early postoperative period, on average, after 9.3 days, 9 patients died. Statistically significant risk factors for death were: chronic hemodialysis, long-term antibiotic therapy, and existing sepsis. Intraoperative complications and postoperative morbidity were not significantly associated with death. The study results imply the need of differentiated approach to bilateral nephrectomy in patients with ESRD and risk factors for fatal outcome. It must be performed on the strong indications since the intervention does not lead to eradication of sepsis. It is advisable to perform "preventive, sanation" bilateral nephrectomy in the "cold period" in patients at risk for developing urosepsis.

    Introduction: Pathological bilateral femoral neck fracture due to renal osteodystrophy is rare. This is a report of a chronic renal failure patient who had sustained bilateral intra-capsular displaced fracture neck of femur following an episode of convulsion and the difficulties encountered in early diagnosis and treatment. The pathophysiology of renal osteodystrophy and the treatment of hip fractures in patients with renal failure are also discussed. Case Report: A 23 years old male patient admitted with h/o dysuria, pyuria and loss of appetite since 3 months. He was a known case of chronic renal failure and reflux nephropathy. On investigating, patient’s renal parameters were high and he was started with haemodialysis. The next day patient had c/o bilateral hip pain and inability to move bilateral lower limbs following an episode of seizure. Radiograph of pelvis showed vertical sub capital fractures of bilateral neck of femur. In this patient, considering his age, general condition & prognosis, an elective surgery in the form of bilateral uncemented modular bipolar hemiarthroplasty was done. Conclusion: Overall risk of hip fracture among patients with chronic renal failure is considerably higher than in the general population, independent of age and gender. Simultaneous spontaneous bilateral fractures of the femoral neck are rare and a delayed diagnosis is usual. The study of etiological factors of these fractures is essential to guide us in choosing the treatment of choice. Obviously patient’s age, life expectancy as well as renal co morbidity has an influence over deciding treatment and outcome. PMID:27299091

    Renal cell carcinoma (RCC) has a propensity for distant organ metastasis and late recurrence, involving not only the ipsilateral but also contralateral kidney. Lingual metastasis by RCC is rare. We present an unusual case of bilateral asynchronous RCC. Involvement of the right kidney was discovered only after a metastatic tongue lesion was diagnosed. The original RCC had been treated by left nephrectomy 14 years previously. Due to end-stage primary pulmonary malignancy, and poor function of the remaining kidney, immunotherapy was unsuitable. Palliative local resection of the lingual metastasis alleviated functional difficulties and was preventative against airway obstruction, but the patient died five months later. PMID:23008792

    A 74-year-old male claudicant who had a significant abdominal aortic stenosis was hydrated before aortic stent placement because of an elevated creatinine level. During the intervention the patient experienced acute abdominal pain with vomiting. No vascular cause was detected. Due to persistant pain, plain radiography and an abdominal CT scan were performed a few hours after the procedure. Images revealed a bilateral renal fornix rupture with a large retroperitoneal fluid collection. The patient was treated conservatively with ureteral double-J placement and percutaneous nephrostomy. The further course was uneventful and the patient was discharged 2 weeks later free of symptoms. Renal fornix rupture is a very rare complication after contrast medium application that can be treated without surgery.

    Introduction: Assessment of treatment outcomes in patients undergoing bilateral single-session retrograde intra-renal surgery (RIRS) for bilateral renal stones up to 1.5 cm. Materials and Methods: Retrospective analysis of 74 patients was done with bilateral renal calculi, who underwent bilateral single-session RIRS at our stone referral hospital from December 2011 to May 2014. The selection criteria for this intervention were patient's preference, failure of other treatments and stone up to 1.5 cm. Patients with creatinine more than 2, pyonephrosis sepsis, bilateral impacted pelviureteric junction calculi were excluded from study. All patients were evaluated with serum biochemistry, urinalysis, urine culture, plain radiography of kidney-ureter-bladder, intravenous urography, renal ultrasonography (USG) and/or computed tomography (CT). Follow-up evaluation included serum biochemistry and postoperative plain film and renal USG. The success rate was defined as patients who were stone-free or only had a residual fragment of less than 4 mm. CT was conducted only in patients with residual stones, which were present in seven patients. Results: A total of 74 patients (50 male, 24 female) with a mean age 39.2 ± 15.2 were included in the present study. The mean stone size was 11.7 ± 2.4 mm. The stone-free rates were 86.84% and 97.29% after the first and second procedures, respectively. In eight patients (10.8%), minor complications were observed, whereas no major complications were noted in the studied group. There was no significant difference in pre- and post-operative serum creatinine levels. Conclusion: In patients with bilateral renal stones up to 1.5 cm bilateral single-session RIRS with flexible ureteroscope can be safely performed with low complication rate. PMID:26834403

This case illustrates that in women with TSC rapid growth from renal AMLs and development of LAM may occur with successive pregnancies. It also stresses the potential for preservation of renal function despite successive bilateral renal surgery of giant AMLs. Moreover, the treatment with a low-dose rapamycin may be an option for LAM treatment. Finally, a low-dose rapamycin may be considered as an adjuvant treatment together to kidney-sparing conservative surgery for renal AMLs. PMID:22125460

    Renal oncocytomas are benign tumors of the kidneys, which are usually diagnosed postoperatively, due to differential diagnostic problems, from a sample of a renal cell carcinoma. The development of a renal oncocytoma in the native kidneys following renal transplantation is a very rare condition and only a few cases have been published in the world literature. In this case report we present a unique case of bilateral multifocal renal oncocytomas of the native kidneys in a female transplant recipient 6 years after renal transplantation. The patient's postoperative clinical course was uneventful and no local recurrence or distant metastasis has been found so far. The pathology, clinical characteristics, and treatment of renal oncocytomas are also reviewed.

    Pulmonary edema and congestive heart failure (both referred to here as PE) have been reported to be complications of bilateral renal artery stenosis or unilateral stenosis in a solitary functioning kidney (both referred to as BRAS). The goals of this study were to determine whether a history of PE was more common in patients with BRAS than in those with unilateral stenosis and a normal contralateral kidney (URAS), and whether recurrent PE could be prevented by renal artery stent placement. We evaluated 90 consecutive patients with renovascular disease who were treated with percutaneous renal artery stent placement. History and clinical follow-up were obtained through chart review and phone contact with referring physicians. Mean follow-up was 18.4 months after stent placement. Twenty-three of 56 (41%) subjects with BRAS had a history of PE before revascularization, compared with four of 34 (12%) subjects with URAS (P = .05). Twenty-five of the 27 patients with history of PE had adequate clinical follow-up. Seventeen of the 22 (77%) subjects with BRAS and history of PE had no further PE after stent placement in one or both renal arteries. The five BRAS subjects with recurrent PE after stent placement had evidence of stent thrombosis or restenosis. In contrast, only one of three (33%) URAS subjects with a history of PE remained free of PE after stent placement. We conclude that PE is a common complication of BRAS, but not of URAS. In patients with BRAS, recurrent PE can be prevented by successful stent placement in one or both renal arteries.

    Tuberous sclerosis complex is a rare multisystemic genetic disorder associated with the development of benign hamartomas. Angiomyolipomas are one such characteristic finding that may be seen in 55–80% of tuberous sclerosis complex patients. While being normally asymptomatic, they can also cause significant morbidity and mortality. We present the case of a patient with tuberous sclerosis complex and recently discovered bilateral renal angiomyolipomas, admitted for hematuria who underwent left renal artery embolization; however, worsening renal function necessitated subsequent nephrectomy. Despite still being mainstays of treatment, invasive interventions are now being recommended for specific patient populations as demonstrated in our case. Emerging strategies targeting the PI3K/AKT/mTOR pathway have been shown to reduce the size of angiomyolipomas and are now used to treat asymptomatic cases >3 cm. Our review discusses these treatment options with the intention of increasing awareness of current recommendations and hopefully leading to increased application of these novel therapies that will reduce the need for invasive interventions.

    Renal carcinomas associated with Xp11.2 translocations/transcription factor 3 (TFE3) gene fusion (Xp11 translocation RCC) are a rare subtype of renal cell carcinoma. A middle-aged Japanese man, who had a medical history of dialysis for more than 12 years, had bilateral renal cancers with a background of acquired cystic disease of the kidney and remarkable deposition of calcium oxalate in the tumorous area. The right renal tumor showed papillary architecture of clear cells with diffuse and strong immunoreactivity for TFE3 and focal and weak positivity for cathepsin K, suggesting a possibility of Xp11 translocation RCC. However, RT-PCR failed to detect any type of the reported fusion genes involving TFE3. Thus, the sample was sent for a TFE3 break-apart FISH assay in a renal tumor consultation service, which reported no evidence of TFE3 gene rearrangement. The right renal tumor was finally diagnosed as papillary renal cell carcinoma with cystic change. We report here a case of bilateral renal cell carcinoma in a patient undergoing long-term dialysis, which showed false-positive immunoreactivity for TFE3 immunostaining. Titration of TFE3 immunohistochemical staining (IHC) should be performed and cross-referenced with the FISH or RT-PCR results to avoid the misinterpretation of TFE3 IHC results.

    In VHL syndrome, renal cell carcinoma is distinctive for its early age of onset, for its bilateral and multifocal involvement. Synchronous solitary urinary bladder metastasis from renal cell carcinoma is extremely rare. We report an unusual case of VHL with bilateral multicentric renal cell carcinoma and synchronous solitary urinary bladder metastasis. To the best of our knowledge this is the first case reported in literature with this combination.

    Although bilateral megaureters are not an infrequent occurrence in the urinary tract, bilateral megaureters associated with bilateral renal pelvis dilatation and a giant urinary bladder appear to be rare. In this paper, a cadaver case of an adult Japanese male with bilateral megaureters is described. In addition to describing and illustrating this case, the anatomy and etiology of these anomalous structures is discussed with a brief review of the literature.

    The purpose of the study was to sterilize renal tuberculous foci in a pretransplantation patient with a laparoscopic hand-assisted approach and to verify the feasibility of bilateral nephrectomy for this indication. This case report is the first description of hand-assisted laparoscopic bilateral nephrectomy for this pathologic condition. The 33-year-old patient had end-stage renal disease from renal tuberculosis. A commercially available hand-assistance device was used through a midline 8-cm supraumbilical incision and with four ports. The procedure was successfully completed. The total operative time was 3 hours and 40 minutes. Estimated blood loss was 250 mL. The postoperative course was uneventful, and clinical follow-up at 3 weeks revealed a successful outcome. Hand-assisted bilateral laparoscopic nephrectomy in patients with chronic renal failure from tuberculosis represents a viable option because it is feasible and effective. The hand-assisted approach increases the safety of the procedure while retaining all the advantages of minimally invasive surgery.

    To report a case of bilateral diffuse uveal melanocytic proliferation associated with renal carcinoma and to illustrate the importance of ancillary examinations to early diagnosis and treatment. Clinical case report. A 56-year-old man reported a 3-day history of visual impairment and scotoma in the right eye. An ophthalmoscopic examination, visual field test, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and systemic evaluation were performed. Fundus examination showed multiple nevus-like uveal pigmented lesions bilaterally. Optical coherence tomography showed a subfoveal serous retinal detachment and focal loss of the retinal pigment epithelium with adjacent areas of retinal pigment epithelial thickening in the right eye, explaining the scotoma on the visual field examination. Indocyanine green angiography showed multiple round areas of hypofluorescence corresponding to the nevus-like pigmented tumors seen on funduscopy, and retinal pigment epithelium damage corresponding to hypoautofluorescence on fundus autofluorescence imaging and window defects points seen on fluorescein angiography bilaterally. After bilateral diffuse uveal melanocytic proliferation diagnosis, a systemic workup showed clear cell carcinoma in the left kidney. Owing to the tumoral size, chemotherapy was administered. Renal carcinoma associated with bilateral diffuse uveal melanocytic proliferation is rare, and the patterns observed in the ancillary examinations, including indocyanine green angiography, are useful for early-stage diagnosis and immediate referral for systemic investigation and treatment.

    Parasitic ovarian dermoid cysts are very rare. We report a rare case of bilateral ovarian dermoid cysts with parasitic teratoma at the hepato renal space measuring 11x11x6 cm while the other was twisted measuring 10x6x5 cm.Right ovary and tube were absent. The mass found at the hepato renal space was surrounded by and adherent to the omentum with viable tubal fimbria like structure at upper surface. Histopathologically both masses were confirmed as mature ovarian teratoma. The etiology of parasitic teratoma would be due to torsion followed by autoamputation and reimplantation of the right ovarian dermoid cyst.

    Smith-Magenis syndrome (SMS) is a contiguous-gene disorder most commonly caused by a deletion of chromosome 17p11.2. We report a 57 year-old man with SMS who presents bilateral renal tumors. This is most likely related to haploinsufficiency of FLCN gene, located in the deleted region, and a known tumor suppressor gene. Haploinsufficiency of FLCN causes Birt-Hogg-Dubé syndrome (BHDS), characterized by pulmonary cysts, renal and skin tumors. The present observation suggests that the follow-up of patients with SMS should also focus on possible manifestations of BHDS.

    To assess the outcomes of percutaneous nephrolithotomy (PCNL) in bilateral staghorn calculi in pediatric patients, we have performed a retrospective analysis. Staghorn calculus is defined as stone that fills a greater part of the pelvic-caliceal system. Still, in developing countries, patients may present with staghorn calculus. PCNL is the preferred treatment modality for staghorn calculus both in adult and children. Our study included fifty-one pediatric patients (<15 years) of bilateral staghorn calculi from 2004 to 2015. Staged PCNL was done after 2-3 days if needed and opposite side PCNL was performed after 10-14 days. Fifty-one patients with bilateral staghorn renal calculi underwent PCNL. The mean age of the study group was 10.25 ± 2.13 (range 3-15). Mean stone burden was 778.3 + 613.4 (range 231-3850 mm(2)). Forty-five patients underwent single puncture, twenty-two patients underwent double punctures whereas six patients underwent triple punctures during first session PCNL procedure. Most common puncture location was through the superior calyx (58.82 %). The mean operating time was 77.25 + 30.21 (range 58-145). After the first session PCNL, the success rate was 76.47 %. Thirteen patients (17 renal units) underwent relook PCNL and seven patients underwent ESWL. Overall complication noted in twenty-four (47.05 %) cases. Most of the complications were minor grade. Percutaneous nephrolithotomy for staghorn calculus in children needs expertise. PCNL in B/L staghorn renal calculus in children is safe and effective. B/L staghorn renal calculi with compromised renal function have higher chance of complications including bleeding.

    The neurolinguistic and cognitive profiles of a patient with mixed transcortical aphasia and non-familial dysphasic dementia associated with progressive, left perisylvian involution are presented. This clinicopathological entity has recently been shown to be an example of a novel class of intrinsic, focal cortical degenerations with sparing of the basal forebrain. The characteristics of the aphasia were unusual. There were occasional literal and verbal paraphasic errors, but no completion phenomenon, embellishment or significant echolalia. Evidence of a generalized lexical disruption was found on detailed analysis of residual abilities in reading, writing and spelling. A newly described form of non-lexical repetition was present, resulting in the patient's inability to correct syntactical and semantic errors. Affective prosodic repetition was intact. A combined paraphasic word-production and semantic anomia was found. These observations combined with evidence of evolving region-specific cognitive impairments suggest that the pathological process resulted in a relative disconnection of integral frontal and parieto-occipital areas from adjacent perisylvian language zones.

    Short rib-polydactyly syndrome (SRPS) is a group of lethal skeletal dysplasia of an autosomal recessive inheritance characterized by markedly narrow ribs, micromelia, and multiple anomalies of major organs. We report a case of type IV SRPS with uncommon associations of polydactyly and bilateral polycystic kidneys, in a 28 week old female fetus. She was born dead to a 28 year old mother, showing a hydropic change, narrow thorax, and shortened limbs with postaxial heptasyndactyly of both hands and feet. Radiologic examination revealed short horizontal ribs, curved short tubular limb bones, small ilia and scapula, and a mild vertebral abnormality. Postmortem examination disclosed pulmonary hypoplasia, pancreatic cysts, hepatic fibrosis, and left persistent superior vena cava. In addition this case had bilateral huge polycystic renal dysplasia that was seldom described in any type of SRPS. Histologic sections of the vertebrae disclosed abnormal enchondral ossification with irregular and retarded hypertrophic zone. PMID:9610623

    Renal duplication accompanied by ureteral ectopia is an uncommon urinary congenital abnormality. We report the case of a 21-year-old girl who suffered from lifelong continuous urinary leakage. She was finally diagnosed with bilateral duplicated collecting systems complicated with right ectopic ureteral orifice - an extremely rare case. The patient underwent ureteric re-implantation for the ectopic side, and her urinary incontinence ceased soon thereafter. In this case, traditional imaging failed to show the exact insertion of an ectopic ureter. However, magnetic resonance urography combined with retrograde intubation radiography successfully depicted the point of ureteric insertion, which may make the diagnostic process accurate and efficient.

    Renal infarction (RI) is frequently misdiagnosed or diagnosed late because of its rarity and nonspecific clinical presentation, which may result in irreversible damage to the renal parenchyma or increase the risk of other embolic events affecting additional organs. Multiple causal mechanisms and cases of idiopathic RI have been reported, but the causal factors are not clear in most cases.Here, we report the case of a patient with heterochronic bilateral RI caused by thrombophilia. Although he had several risk factors for hypercoagulation disorders, two gene mutations-MTHFR 677 C>T and PLG 1858G>A-were identified by genome sequencing of the entire exome. The findings suggest the possibility of a synergistic relationship between the two gene mutations.Thus, screening for gene mutations may provide additional clues for clarifying the cause of RI and thrombophilia.

    INTRODUCTION: Total hip replacement is generally proposed for renal transplant patients with avascular osteonecrosis of the femoral head. PURPOSE: The purpose of the study is to report the long-term outcome after rehabilitation of bilateral total hip arthroplasty in a patient with renal transplantation suffering from avascular osteonecrosis of the both femoral heads. MATERIAL AND METHOD: The patient S.D, 49 years old at follow-up. Few months after renal transplantation, the patient had got avascular osteonecrosis of both femoral head. One year after transplantation the total hip arthroplasty for both hip joints were performed. Three years later repeat total hip arthroplasty surgery for left hip was performed. After any surgery intervention the patient was referred for inpatient rehabilitation. For clinical assessment the clinical findings and Harris Hip Score have been used. The rehabilitation program consisted of exercises, occupational therapy, and patient education. RESULTS: After any rehabilitation treatment the patient had improvement of clinical findings. At follow-up assessment outcome for both hip function was good - Harris Hip Score was 81 points. CONCLUSION: Rehabilitation is integral part of multidisciplinary treatment of renal transplant recipient after total hip arthroplasty. Regular exercise training of these patients is very important for improving of their long-term outcome. PMID:27275350

    Yield of causative variants in hypertrophic cardiomyopathy (HCM) is increased in some probands, suggesting different clinical subgroups of disease occur. We hypothesized that a negative family history and no sarcomere mutations represent a nonfamilial subgroup of HCM. We sought to determine the prevalence, natural history, and potential clinical implications of this nonfamilial subgroup of HCM. Four hundred and thirteen unrelated probands with HCM seen in a specialized HCM center between 2002 and 2015 and genetic testing performed were included in this retrospective cohort study. There were 251 (61%) probands with no reported family history of HCM, including 166 (40% of total) probands with no sarcomere mutation, that is, nonfamilial HCM. Quantified family pedigree data revealed no difference in mean number of first-degree relatives screened between nonfamilial and sarcomere-positive groups. Adjusted predictors of nonfamilial status were older age (odds ratio, 1.04; 95% confidence interval, 1.02-1.06; P=0.0001), male sex (odds ratio, 1.96; 95% confidence interval, 1.11-3.45; P=0.02), hypertension (odds ratio, 2.80; 95% confidence interval, 1.57-5.00; P=0.0005), and nonasymmetric septal morphology (odds ratio, 3.41; 95% confidence interval, 1.64-7.08; P=0.001). They had a less severe clinical course with greater event-free survival from major cardiac events (P=0.04) compared with sarcomere-positive HCM probands. Genotype prediction scores showed good performance in identifying genotype-positive patients (area under the curve, 0.71-0.75) and, in combination with pedigree characteristics, were further improved. Approximately 40% of HCM probands have a nonfamilial subtype, with later onset and less severe clinical course. We propose a revised clinical pathway for management, highlighting the role of genetic testing, a detailed pedigree, and refined clinical surveillance recommendations for family members. © 2017 American Heart Association, Inc.

    Purpose Secondary hyperparathyroidism (SHPT) develops in patients with chronic renal failure. This study aimed to compare analgesic efficacy in SHPT patients who undergo subtotal parathyroidectomy after superficial versus deep cervical plexus block. Methods Sixty chronic renal failure patients with SPHT scheduled for subtotal parathyroidectomy were randomized to receive general anesthesia (group GA), general anesthesia plus bilateral superficial and deep cervical plexus block (group BD), or general anesthesia plus bilateral superficial cervical plexus block (group BS) (n = 20). Bilateral superficial cervical plexus block or combined superficial and deep cervical plexus block with 0.5% ropivacaine was administered. Postoperative pain was assessed using visual analogue scale (VAS). Results VAS score at 1 hour, 4 hours, and 8 hours after operation was 3.71 ± 0.60, 2.72 ± 0.54, 2.17 ± 0.75 in BS group; 4.00 ± 0.28, 2.89 ± 0.21, and 2.46 ± 1.01 in BD group, significantly lower than in GA group (6.50 ± 0.50, 5.02 ± 0.54, and 4.86 ± 0.51, respectively). The dosage of tramadol was 109.0 ± 35.2 mg in BS group and 93.0 ± 24.52 mg in BD group, significantly lower than in GA group (300.0 ± 27.13 mg). The incidence of complications in GA group (90%) was significantly higher than in BS group (30%) and BD group (15%). Serum glucose and norepinephrine levels were significantly higher at 1 hour, 4 hours, and 8 hours after operation, but returned to baseline levels at 24 hours after operation. Conclusion Superficial cervical plexus block or combined superficial and deep cervical plexus block effectively reduces postoperative pain, stress response, and complications in SHPT patients who undergo subtotal parathyroidectomy.

    The aim of this study is to present the treatment of a juxtarenal inflammatory aneurysm using a Nellix device (Endologix, Inc., Irvine, CA) to seal the entire aneurysmatic aorta combined with bilateral iliac-renal bypass using the Gore hybrid vascular graft (W. L. Gore & Associates, Inc., Flagstaff, AZ). A 63-year-old man was diagnosed with a 6-cm juxtarenal inflammatory aneurysm. It was initially decided to treat him with an aorto-aortic bypass and to revascularize the 2 renal arteries with "graft to renal artery bypass" using Gore hybrid vascular grafts. Due to the high intraoperative bleeding preparing the proximal neck and the tight adhesion of the aorta to the adjacent structures, we decided to change our plans and to treat the patient using the Nellix system combined with bilateral iliac-renal bypass using the Gore hybrid vascular grafts. Contrast computed tomography control at 1 month showed complete sealing of the aneurysm sac and patent iliac renal bypasses. The reported case demonstrated that the Nellix Endovascular Aneurysm Sealing system combined with Gore hybrid vascular grafts for bilateral iliac-renal bypass showed that it can be an effective modality for the treatment of juxtarenal, inflammatory aortic aneurysm and revascularization of the renal arteries from the distal iliac arteries.

    Congenital giant megaureter (CGM) is uncommon in the pediatric population. The major clinical presentations are marked protruberances and abdominal cysts. We reported a case of CGM with almost the whole left ureter dilation accompanied with a 1 cm stricture at the entrance of the bladder and renal dysplasia, immediately compressing the contralateral ureter and causing bilateral hydronephrosis for the first time. At one-stage of the operation, a left nephrostomy with a right ureterolysis were performed, and a poor left kidney function was found. Then, the left kidney and ureter were cut off by nephroureterectomy at the second-stage. Eventually, the follow-up showed that the patient recovered well by abdominal ultrasound. Based on the findings of these reported literatures, CGM is rare. The physical and imaging examinations are essential for the diagnosis of CGM, and the appropriate treatment methods should be performed based on patients' specific condition.

    Purpose: To assess in vivo 1) MR-guided percutaneous transluminal renal angioplasty (PTRA) in experimental bilateral rabbit renal artery stenosis (RAS); 2) postprocedural follow-up by gadolinium-enhanced MR angiography versus histomorphometry.Methods: Fifteen male NZW rabbits of mean weight 4.0 kg (range 3.5-4.2 kg) underwent bilateral RAS induction by combined overdilation-deendothelialization with a gadolinium-filled balloon, passively MR-guided by the artifact of a 0.014-inch guidewire. After 4 weeks the rabbits were randomized into two groups: group A (n = 8) underwent right-sided PTRA for treatment of RAS, group B (n = 7) underwent left-sided PTRA. After another 4 weeks the rabbits were killed to assess by histomorphometry recurrent stenosis and contralateral induction injury stenosis lesions. Each step was preceded by gadolinium-enhanced three-dimensional MR angiography, and the cortex-to-aorta (C/A) signal intensity ratio was calculated.Results: RAS induction was successful in all cases. Fourteen arteries developed restenosis and 13 only initial stenosis. MR-guided PTRAs were feasible in 22 arteries (73%). For a successful catheterization of the ostium (20 arteries, 66% success rate), 10-25 steps were required. Five to eight steps were required for balloon localization and inflation for each PTRA. The restenosis effect was reflected by a 16% (12%-27%) decrease in C/A values on MR angiograms (p < 0.05).Conclusion: MR guidance and MR angiography represent a feasible, less invasive alternative for performing and assessing experimental PTRA in RAS.

    Metastasis from renal cell carcinoma (RCC) to the testis is rare. This case report presented an extremely rare case of simultaneous bilateral testicular metastases from RCC in a 65-year-old man who had experienced indolent scrotal enlargement over a period of several months. Scrotal ultrasonography showed 4.0- and 2.0-cm-sized masses in the left and right testes, respectively. Contrast-enhanced computed tomography identified multiple tumors in the kidneys, the pancreas and the left adrenal gland. Left orchiectomy and pathological examination were performed and indicated testicular metastasis from clear cell RCC. The patient underwent complete surgical resection of all residual lesions. Postoperative follow-up examination without adjuvant therapy identified no recurrence over 11 months. This study also reviewed existing literature and determined that retrograde venous spread from the primary kidney tumor to the testis may be an important pathway for testicular metastasis from RCC. In conclusion, RCC can result in testicular metastases not only unilaterally, but also bilaterally, as was observed in the present case. PMID:24944706

    Mesenchymal chondrosarcoma (MC) is a rare malignant cartilaginous forming tumor. MC of the kidney is extremely rare, with only seven cases reported in the literature. The present study described the case of a 17-year-old male, who presented with sudden severe pain in the right flank and a high fever. Imaging studies demonstrated a large soft heterogeneous mass (7.8×9.5×15 cm) located between the liver and right kidney with no clear demarcation, and a well-demarcated mass (1.3×2.4 cm) with patchy dense calcification occupying the left renal pelvis. Following the diagnosis of a Wilms' tumor, the patient underwent a right radical nephrectomy and the pathological diagnosis was MC of the kidney. To the best of our knowledge, the current study presents the first case of MC with bilateral kidney invasion and calcification in the renal pelvis. In addition, the clinical, radiological and pathological features, and the management of this unusual neoplasm were discussed.

    We present a 36-year-old female patient who was injured in the pelvic region by a mortar shell fragment. The trauma comprised a complex lesion to both ureters, to the urinary bladder, and to the pelvic brim. The ruptured urinary bladder was sutured and a bilateral ureterocutaneostomy was performed in a hospital near the front line. Because of a large scar and the right ureter necrosis, a kidney autotransplant was performed 3 months later. A left ureterocystoneostomy was done. Five years later, because of urosepsis and hydronephrosis caused by a ureteral calculus, a nephrostomy was placed in the proximal right ureter, antibiotic treatment was prescribed, and the calculus was managed by crushing the stones using extracorporeal shock wave lithotripsy. Ten years after the initial trauma, the patient is well, has normal micturition, and both of her kidneys are functioning normally.

    A biopsy procedure was developed to provide serial kidney samples from standing steers. Ten clinically normal steers were given intramuscular injections of gentamicin sulfate, 4 mg/kg body weight. Renal biopsy was performed at 5 separate times. After feed was withheld for 24 h, laparoscopic surgery was performed in standing stocks. Acepromazine, xylazine, and butorphanol were used for sedation and analgesia, and 2% lidocaine was used for local anesthesia. Two incisions approximately 2 cm long were made in the paralumbar fossa to allow for trocar introduction. The abdomen was insufflated with CO2 and, with endoscopic guidance, a biopsy forceps used to remove a kidney sample 2 to 3 mm in diameter, by either a left or a right abdominal approach. Each operation was recorded on videotape, and images were also captured with a digital medical device system. Respiration, heart rate, temperature, appetite, attitude, and postural positions were evaluated at 12, 24, 48, and 72 h after surgery. The 51 laparoscopic procedures provided 48 renal samples (approximately 100 mg each). The 1st and 2nd samples were from the right kidney, and the 3rd sample was from either the left or the right kidney; the 4th and 5th samples were from the left kidney. Adhesions made an approach from the right side difficult for the 3rd sample. No clinical changes were observed in 9 steers after the procedure. One steer died after the 3rd procedure owing to hemorrhage.

    Abel and Annon's (Reducing deviant sexual arousal through satisfaction, Denver, Colo., 1982) suggested combination of 'directed masturbation' and 'satiation' to alter deviant sexual preferences, was applied to 10 nonfamilial child molesters. Post-treatment assessments revealed significant reductions in deviant arousal as was expected, but unfortunately there were also reductions in appropriate arousal although these changes did not achieve statistical significance. The results are discussed in terms of their meaning but it is concluded that empirical support for these clinically popular procedures remains weak.

    Background & objectives: The role of cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in congenital bilateral absence of vas deferens and unilateral renal agenesis (CBAVD-URA) has been controversial. Here, we report the cases of five Indian males with CBAVD-URA. The objective was to evaluate the presence or absence of CFTR gene mutations and variants in CBAVD-URA. The female partners of these males were also screened for cystic fibrosis (CF) carrier status. Methods: Direct DNA sequencing of CFTR gene was carried out in five Indian infertile males having CBAVD-URA. Female partners (n=5) and healthy controls (n=32) were also screened. Results: Three potential regulatory CFTR gene variants (c.1540A>G, c.2694T>G and c.4521G>A) were detected along with IVS8-5T mutation in three infertile males with CBAVD-URA. Five novel CFTR gene variants (c.621+91A>G, c.2752+106A>T, c.2751+85_88delTA, c.3120+529InsC and c.4375-69C>T), four potential regulatory CFTR gene variants (M470V, T854T, P1290P, Q1463Q) and seven previously reported CFTR gene variants (c.196+12T>C, c.875+40A>G, c.3041-71G>C, c.3271+42A>T, c.3272-93T>C, c.3500-140A>C and c.3601-65C>A) were detected in infertile men having CBAVD and renal anomalies Interpretation & conclusions: Based on our findings, we speculate that CBAVD-URA may also be attributed to CFTR gene mutations and can be considered as CFTR-related disorder (CFTR-RD). The CFTR gene mutation screening may be offered to CBAVD-URA men and their female partners undergoing ICSI. Further studies need to be done in a large sample to confirm the findings. PMID:27488005

    Structural brain abnormalities are consistently reported in schizophrenic subjects but the etiology of these abnormalities remains unclear. We tested the contribution of genetic predisposition and obstetric complications to the structural brain abnormalities found in schizophrenic probands and their relatives. MRI scans were carried out on 35 schizophrenic probands from families multiply affected with the disorder, and 63 of their unaffected relatives, including 10 parents who appeared to transmit genetic risk to their children; as well as 31 schizophrenic probands from families with no other affected members, 33 of their unaffected relatives; and finally 68 controls. Volumetric measurements of whole brain, lateral ventricles, third ventricle, cerebellum, and temporal lobes were completed for each subject. The impact of obstetric complications on brain structure was assessed across the gradient of presumed genetic predisposition. Both groups of schizophrenic probands displayed enlargement of the lateral and third ventricles, and there was a gradient of ventricular enlargement amongst the unaffected relatives in proportion to their likelihood of carrying schizophrenic genes. Ventricular enlargement was largely confined to males in both probands and unaffected relatives. Obstetric complications were associated with ventricular enlargement only in the familial probands. Non-familial probands displayed reduced volume of the temporal lobes bilaterally. In families with several schizophrenic members, ventricular enlargement is a marker for genetic liability, particularly in males. Individuals inheriting the susceptibility to schizophrenia appear particularly prone to develop ventricular enlargement in response to obstetric complications.

    Several lines of evidence have demonstrated the anti-inflammatory and cytoprotective effects of alpha-1-antitrypsin (AAT), the major serum serine protease inhibitor. The aim of the present study was to investigate the effects of human AAT (hAAT) monotherapy during the early and recovery phase of ischemia-induced acute kidney injury. Mild renal ischemia-reperfusion (I/R) injury was induced in male C57Bl/6 mice by bilateral clamping of the renal artery and vein for 20 min. hAAT (80 mg/kg, Prolastin®) was administered daily intraperitoneally (i.p.) from day -1 until day 7 after surgery. Control animals received the same amount of human serum albumin (hAlb). Plasma, urine and kidneys were collected at 2h, 1, 2, 3, 8 and 15 days after reperfusion for histological and biochemical analysis. hAAT partially preserved renal function and tubular integrity after induction of bilateral kidney I/R injury, which was accompanied with reduced renal influx of macrophages and a significant decrease of neutrophil gelatinase-associated lipocalin (NGAL) protein levels in urine and plasma. During the recovery phase, hAAT significantly decreased kidney injury molecule-1 (KIM-1) protein levels in urine but showed no significant effect on renal fibrosis. Although the observed effect size of hAAT administration was limited and therefore the clinical relevance of our findings should be evaluated carefully, these data support the potential of this natural protein to ameliorate ischemic and inflammatory conditions.

    We describe the clinical course and have characterised anatomically and genetically a unique case of a newborn with bilateral hypoplasia of pulmonary arteries, consecutive extremely hypoplastic lung tissue and associated unilateral renal agenesis. Intrauterine oxygenation by the placenta seemed to have allowed normotrophic body maturity but immediately after delivery, in the third trimester, progressive hypoxemia developed and the newborn succumbed to acute respiratory failure. Genetic analysis by array-based comparative genomic hybridisation and quantitative PCR revealed duplication of 1p21, which, however, might not be the disease causing aberration. This case might represent an extreme form of previously reported, rare cases with simultaneous dysorganogenesis of lungs and kidneys.

    Prevalence and phenotype of BRCA mutation can vary by race. The purpose of this study is to evaluate the prevalence of BRCA1/2 mutations in non-familial breast cancer patients with high risks in Korea. A subset of 758 patients was selected for this study from the KOHBRA nationwide multicenter prospective cohort study. Mutations in BRCA1/2 genes were tested using fluorescent-conformation sensitive gel electrophoresis, denaturing high performance liquid chromatography or direct sequencing. Mutation of BRCA1/2 genes were identified in 65 (8.6%) patients among total 758 patients [BRCA1 mutation: 25 (3.3%), BRCA2 mutation: 40 (5.3%)]. According to risk groups, mutation of BRCA1/2 genes were identified in 53 (8.5%) of 625 early onset patients (age ≤ 40), in 22 (17.7%) of 124 bilateral breast cancer patients, in 3 (50.0%) of 6 breast and ovarian cancer patients, in one (5.9%) of 17 male breast cancer patients, in 5 cases (7.6%) of 66 multiple organ cancer patients. The most common mutation was 509C>A for BRCA1 and 7708C>T for BRCA2. The prevalence of BRCA1/2 mutations by age in early onset patients was significantly different (age <35 vs age ≥35; 10.0 vs 2.9%, p = 0.0007). BRCA1/2 mutations for non-familial Korean breast cancer patients were detected at a high rate, particularly, in patients with early onset of less than 35 years of age, bilateral breast cancer, and breast and ovarian cancer. Individualized genetic counseling should be offered for non-familial breast cancer patients with these risk factors.

    Patients with bilateral central vein stenosis present a unique challenge: treatment options are limited, largely unproven and associated with reputedly poor outcomes. Our aim was to compare patency rates of different access and renal replacement treatment (RRT) modalities in patients with bilateral central vein stenosis/occlusion. Data on all patients presenting to a tertiary referral vascular access centre with end-stage vascular access (defined by bilateral central vein stenosis/occlusion with loss of upper limb access) over a 5-year period were included. 3, 6 and 12-month patencies of translumbar catheters (TLs), tunnelled femoral catheters (Fem), native long saphenous vein loops (SV), prosthetic mid-thigh loop grafts (ThGr), peritoneal dialysis (PD), and expedited donation after cardiac death (DCD) cadaveric renal transplants (Tx) via local allocation policies were compared using log-rank test. Kaplan-Meier survival analysis was used to estimate long-term access survival. One hundred forty-six vascular access modalities were attempted in 62 patients (62 Fem, 25 TL, 15 SV, 25 ThGr, 8 PD, 11 Tx). Median follow-up was 876±57 days. Three, 6 and 12-month primary-assisted patencies for each modality were as follows: Fem: 75.4%, 60% and 28%; TL: 88%, 65% and 50%; SV: 87.5%, 60% and 44.6%; ThGr: 64%, 38% and 23.5%; PD: 62.5%, 62.5% and 50%; Tx: 72.7%, 72.7% and 72.7%. SV had better secondary patency at 900 days (76.9%) than ThGr (49.2%) or Fem (35.8%) (p<0.01). No patients died as a result of loss of access. Patients with bilateral central vein stenosis often require more than one vascular access modality to achieve a "personal access solution." Native long saphenous vein loops provided the best long-term patency. Expedited renal transplantation with priority local allocation of DCD organs to patients with precarious vascular access provides a potential solution to this difficult problem.

    There are a large number of non-family (NF) genes that do not cluster into families with three or more members per genome. While gene families have been extensively studied, a systematic analysis of NF genes has not been reported. We performed comparative studies on NF genes in 14 plant species. Based on the clustering of protein sequences, we identified ~94 000 NF genes across these species that were divided into five evolutionary groups: Viridiplantae wide, angiosperm specific, monocot specific, dicot specific, and those that were species specific. Our analysis revealed that the NF genes resulted largely from less frequent gene duplications and/or a higher rate of gene loss after segmental duplication relative to genes in both lowcopy- number families (LF; 3 10 copies per genome) and high-copy-number families (HF; >10 copies). Furthermore, we identified functions enriched in the NF gene set as compared with the HF genes. We found that NF genes were involved in essential biological processes shared by all plant lineages (e.g. photosynthesis and translation), as well as gene regulation and stress responses associated with phylogenetic diversification. In particular, our analysis of an Arabidopsis protein protein interaction network revealed that hub proteins with the top 10% most connections were over-represented in the NF set relative to the HF set. This research highlights the roles that NF genes may play in evolutionary and functional genomics research.

    Scholars and policy makers have expressed concern that social and economic changes occurring throughout Asia are threatening the well-being of older adults by undercutting their systems of family support. Using a sample of 1,654 men and women aged 45 and older from the Chitwan Valley Family Study in Nepal, we evaluated the relationship between individuals’ nonfamily experiences, such as education, travel, and nonfamily living, and their likelihood of receiving personal care in older adulthood. Overall, we found that among individuals in poor health, those who had received more education, traveled to the capital city, or lived away from their families were less likely to have received personal care in the previous two weeks than adults who had not had these experiences. Our findings provide evidence that although familial connections remain strong in Nepal, experiences in new nonfamily social contexts are tied to lower levels of care receipt. PMID:24999289

    2005-11-01

    This study examines the changing effects of non-family activities on the age of transition to first marriage in four cohorts of individuals across 45 years in the Chitwan Valley, Nepal. The results indicate that school enrolment had a negative effect on both men's and women's marriage rates, while total years of schooling had a positive effect on men's marriage rates. Non-family employment experiences increased marriage rates for men only. Analysing the effects of schooling and employment over time suggests that school enrolment became a growing deterrent to marriage for both sexes, and that non-family employment became an increasingly desirable attribute in men. The results are consistent with changing views about sex roles and schooling over time in the region, as the roles of student and spouse became more distinct. The results also suggest an increasing integration of husbands in the non-family labour market.

    To evaluate the serum aldosterone (Ald)/plasmatic renin activity (PRA) ratio as a surrogate marker of renin-angiotensin-aldosterone system status in unilateral (Uni)- and bilateral (Bi)-renal artery stenosis (RAS). Seven hundred and eight hypertensive patients (HTP) were studied. Intermediate and high pretest risk of RAS was detected in 66 HTP who subsequently underwent renal gadolinium-enhanced magnetic resonance and arteriography. After application of exclusion criteria 51 HTP remained: 16 with Uni-RAS, 16 with Bi-RAS and 19 essential hypertensives with normal arteries. Nineteen normotensive individuals were also studied. Ald and PRA were determined before and after stenosis resolution by balloon angioplasty and stent implantation. Ald/PRA (ng/dl per (ng/ml per h(-1))) was markedly high in Bi-RAS (5.92 +/- 2.30, P < 0.001), and markedly low in Uni-RAS (0.38 +/- 0.17, P < 0.001) versus essential hypertensives (1.52 +/- 2.02). Multilevel likelihood ratios for Bi-RAS were positive for Ald/PRA higher than 3.6, negative for Ald/PRA lower than 0.2, and neutral for Ald/PRA at least 0.2 and 3.6 or less. ROC analysis identified Ald/PRA lower than 0.5 and Ald/PRA higher than 3.7 to have the best sensitivity and specificity to detect Uni-RAS and Bi-RAS, respectively. In Uni-RAS, but not in Bi-RAS, postinterventional PRA was significantly lower than basal PRA. In Uni-RAS and Bi-RAS, postinterventional Ald was approximately 30% and approximately three times lower than basal Ald, respectively. In essential hypertensives, PRA and Ald showed no changes in the same period. In the population studied, Ald, PRA and Ald/PRA were significantly different among essential hypertensives, and HTP with Uni-RAS or Bi-RAS. Studies with a higher number of patients will allow exploration of the usefulness of pharmacologic aldosterone blockade in Bi-RAS, and to assess the relevance of Ald/PRA to differentiate Uni-RAS from Bi-RAS.

  16. Elderly out-of-hospital cardiac arrest has worse outcomes with a family bystander than a non-family bystander

    2012-01-01

    Background A growing elderly population along with advances in equipment and approaches for pre-hospital resuscitation necessitates up-to-date information when developing policies to improve elderly out-of-hospital cardiac arrest (OHCA) outcomes. We examined the effects of bystander type (family or non-family) intervention on 1-month outcomes of witnessed elderly OHCA patients. Methods Data from a total of 85,588 witnessed OHCA events in patients aged ≥65 years, which occurred from 2005 to 2008, were obtained from a nationwide population-based database. Patients were stratified into three age categories (65–74, 75–84, ≥85 years), and the effects of bystander type (family or non-family) on initial cardiac rhythm, rate of bystander cardiopulmonary resuscitation (CPR), and 1-month outcomes were assessed. Results The overall survival rate was 6.9% (65–74 years: 9.8%, 75–84 years: 6.9%, ≥85 years: 4.6%). Initial VF/VT was recorded in 11.1% of cases with a family bystander and 12.9% of cases with a non-family bystander. The rate of bystander CPR was constant across the age categories in patients with a family bystander and increased with advancing age categories in patients with a non-family bystander. Patients having a non-family bystander were associated with significantly higher 1-month rates of survival (OR: 1.26; 95% CI: 1.19–1.33) and favorable neurological status (OR: 1.47; 95% CI: 1.34–1.60). Conclusions Elderly patient OHCA events witnessed by a family bystander were associated with worse 1-month outcomes than those witnessed by a non-family bystander. Healthcare providers should consider targeting potential family bystanders for CPR education to increase the rate and quality of bystander CPR. PMID:23137233

Lesions are characterized by the replacement of bone with fibrovascular tissue containing many multinucleated giant cells. Most studies have reported cherubism to be familial and with bilateral involvement of the mandibles. The authors describe a nonfamilial case of cherubism, involving both the mandible and the maxilla, in a 4-year-old female child with slowly enlarging, painless, symmetrical swelling of both cheeks. Cherubism is a rare disease that is usually limited to the mandible, but the maxilla may be involved. Computed tomography scan and biopsy are helpful for early diagnosis. PMID:26656340

    Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of bilateral ureteric obstruction in a 14-year-old boy nine days after surgery for an acute appendicitis. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated bilateral hydronephrosis of moderate degree. No abscess was found with CT but presence of millimetric stones on both distal ureters was shown, with bilateral calyceal dilatation. Cystoscopy revealed inflammatory changes in the bladder base. Following introduction of bilateral ureteric stents, there was rapid normalisation of urinary output and serum creatinine. PMID:26295001

    We present a case of bilateral lesions in a 50-year-old man, which were on first impression mistaken for and initially treated as bilateral cellulitis. We propose that bilateral cellulitis, as opposed to unilateral, is rare and that other aetiologies should be considered in evaluating a patient with bilateral lesions. The differential diagnosis includes stasis-dermatitis, lipodermatosclerosis, lymphoedema and vascular lesions such as Kaposi sarcoma, as was identified in this case. Early consultation with dermatology and biopsy in unclear cases mitigates the unnecessary use of prolonged antibiotics, antibiotic resistance and Clostridium difficile infections. HIV testing is an essential screening test in all adults who present with non-specific viral symptoms and rash.

    Consanguineous marriage is quite prevalent in the Sultanate of Oman, with up to 45% of marriages being consanguineous. The aim of this study was to determine demographic, clinical and serological characteristics between familial and non-familial cases of juvenile systemic lupus erythematosus (SLE) in a highly consanguineous region such as Oman. Hospital medical records were retrospectively reviewed for 44 consecutive children with juvenile SLE seen at Sultan Qaboos University Hospital, 16 with familial SLE and 28 with non-familial SLE. All the children included in the study were Omani, diagnosed before 13 years of age, and fulfilled the 1982 revised ACR criteria. Analyses were performed using descriptive statistics. There were largely no significant differences in the clinical and serological manifestations between the two cohorts. However, the familial SLE group was associated with worse SLEDAI score at onset of diagnosis compared with the non-familial cohort (12 vs. 17; p = 0.003) suggesting a greater severity of disease in the familial group. Even though the rate of familial SLE is higher in Oman (36%) compared with the Western world (10-12%), it appears that familial and non-familial SLE cases are in fact similar disease entities in both the West and the Middle Eastern countries.

    The author reports the case of a well and fit patient who presented herself to the emergency department and was found to have bilateral emphysematous pyelonephritis. She was admitted to the intensive care where she was initially treated conservatively with antibiotics, percutaneous drainage and continuous renal replacement therapy, but her condition deteriorated. She underwent a left total nephrectomy and a partial right nephrectomy that resulted in remarkable improvement. The patient started passing urine spontaneously, so no haemofiltration was required. She was discharged home and her case was followed-up by an urologist and nephrologist. This case lays emphasis on thoroughly investigating and managing a patient with bilateral emphysematous pyelonephritis and, in relation to its management, on the dilemma of whether the treatment of choice should be conservative or surgical.

    Juvenile polyposis coli (JPC) is an uncommon condition, manifesting as hamartomatous gastrointestinal polyposis with potential malignancy. This report describes a 15-month-old girl who was diagnosed to have nonfamilial JPC accompanied by macrocephaly, clubbed fingers, and mental retardation. Radiography of the colon by a barium enema and total colonoscopy demonstrated numerous colonic polyps. A barium meal study did not show any abnormality in the stomach, duodenum, or small intestine. She died at 6 years of age from hemorrhagic shock due to massive lower gastrointestinal bleeding associated with a rectal prolapse. The related literature is reviewed, and the treatments and complications of JPC in children are also discussed. We emphasize that family members of patients diagnosed with juvenile polyposis should be questioned and undergo appropriate examinations of the entire intestine from the stomach to the rectum.

    Juvenile polyposis syndrome is an uncommon hamartomatous disorder with gastrointestinal (GI) manifestations of varying degree and malignant potential. We report the cases of an 8-year-old girl and a 5-year-old girl who suffered massive lower GI hemorrhage. Neither patient had a family history of polyposis. After the patients were stabilized, radiological evaluation, laparotomy, and intraoperative colonoscopy revealed multiple polyps in the colon. Both patients underwent total colectomy, mucosal proctectomy, and ileoanal anastomosis. The diagnosis of nonfamilial juvenile polyposis was based on the histological findings and the absence of a family history. To our knowledge, this presentation of juvenile polyposis has been reported only twice before. We discuss the clinical features and diagnosis of juvenile polyposis and the treatment options. Although juvenile polyposis is a rare condition in children, it should be considered in the differential diagnosis of life-threatening GI hemorrhage.

  6. Bilateral vestibulopathy.

    2016-01-01

    The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response. If the results of the bedside HIT are unclear, angular VOR function should be quantified by a video-oculography system (vHIT). An additional test supporting the diagnosis is dynamic visual acuity. Cervical and ocular vestibular-evoked myogenic potentials (c/oVEMP) may also be reduced or absent, indicating impaired otolith function. There are different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low- and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration (cerebellar ataxia, neuropathy, vestibular areflexia syndrome=CANVAS). In general, in the long term there is no improvement of vestibular function. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral

    Childhood cystic partially differentiated nephroblastoma (CPDN) is an uncommon renal neoplasm. Bilateral CPDN or CPDN co-existing with a cystic nephroma/Wilms tumour is extremely rare. Treatment of CPDN is by complete surgical excision. Although local recurrences are uncommon, distant metastases have not been described. We present a case of bilateral CPDN that, after complete excision, recurred as bilateral cystic Wilms tumour. To the best of our knowledge, this is the first reported case in the literature where a bilateral CPDN has recurred as bilateral Wilms tumour.

    Hypercalcitoninemia in gastroenteropancreatic tumors associated with calcitonin immunoreactivity is rare. We report here two patients in whom pancreatic neuroendocrine tumors both contained and secreted immunoreactive calcitonin. Both patients experienced elevated basal calcitonin immunoreactivity. The peak responses of immunoreactive calcitonin occurred 5 minutes after pentagastrin administration in these two patients and were 30% and 180% above basal concentrations corresponding to peak increments of 0.39 and 8.78 ng/ml, respectively. The immunoreactive calcitonin response to pentagastrin in these two patients was not significantly different from that seen among five patients with medullary carcinoma of the thyroid gland. It does not appear that immunoreactive calcitonin responses to pentagastrin stimulation will discriminate between patients with medullary carcinoma of the thyroid gland and those with nonfamilial, gastroenteropancreatic neuroendocrine tumors that express calcitonin immunoreactivity. In patients with secretory diarrhea and/or flushing, an elevated level of immunoreactive calcitonin, in the absence of a thyroid mass in the neck, may herald the presence of a gastroenteropancreatic neuroendocrine tumor.

    Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder characterised by various phenotypic features like hyperpigmented spots, neurofibromas, Lisch nodules, skeletal abnormalities and tendency to develop neoplasms. Only few cases of Non-Familial Spinal Neurofibromatosis-1 (Non-FSNF1) have been described in literature with tumors involving the spinal roots at every level being even rarer. We reported an interesting case of bilateral symmetrical cervical neurofibroma with multiple spinal neurofibromas appearing as mirror image on CT, associated with non familial NF-1 as a rare presentation in a 25-year-old adult male.

    Heart failure (HF) is characterized by cardiac dysfunction along with autonomic unbalance that is associated with increased renin-angiotensin system (RAS) activity and elevated levels of proinflammatory cytokines (PICs). Renal denervation (RD) has been shown to improve cardiac function in HF, but the protective mechanisms remain unclear. The present study tested the hypothesis that RD ameliorates isoproterenol- (ISO-) induced HF through regulation of brain RAS and PICs. Chronic ISO infusion resulted in remarked decrease in blood pressure (BP) and increase in heart rate and cardiac dysfunction, which was accompanied by increased BP variability and decreased baroreflex sensitivity and HR variability. Most of these adverse effects of ISO on cardiac and autonomic function were reversed by RD. Furthermore, ISO upregulated mRNA and protein expressions of several components of the RAS and PICs in the lamina terminalis and hypothalamic paraventricular nucleus, two forebrain nuclei involved in cardiovascular regulations. RD significantly inhibited the upregulation of these genes. Either intracerebroventricular AT1-R antagonist, irbesartan, or TNF-α inhibitor, etanercept, mimicked the beneficial actions of RD in the ISO-induced HF. The results suggest that the RD restores autonomic balance and ameliorates ISO-induced HF and that the downregulated RAS and PICs in the brain contribute to these beneficial effects of RD.

    Brugada syndrome (BrS) is one of the ion channelopathies associated with sudden cardiac death (SCD). The most common BrS-associated gene (SCN5A) only accounts for approximately 20-25% of BrS patients. This study aims to identify novel mutations across human ion channels in non-familial BrS patients without SCN5A variants through disease-targeted sequencing. We performed disease-targeted multi-gene sequencing across 133 human ion channel genes and 12 reported BrS-associated genes in 15 unrelated, non-familial BrS patients without SCN5A variants. Candidate variants were validated by mass spectrometry and Sanger sequencing. Five de novo mutations were identified in four genes (SCNN1A, KCNJ16, KCNB2, and KCNT1) in three BrS patients (20%). Two of the three patients presented SCD and one had syncope. Interestingly, the two patients presented with SCD had compound mutations (SCNN1A:Arg350Gln and KCNB2:Glu522Lys; SCNN1A:Arg597* and KCNJ16:Ser261Gly). Importantly, two SCNN1A mutations were identified from different families. The KCNT1:Arg1106Gln mutation was identified in a patient with syncope. Bioinformatics algorithms predicted severe functional interruptions in these four mutation loci, suggesting their pivotal roles in BrS. This study identified four novel BrS-associated genes and indicated the effectiveness of this disease-targeted sequencing across ion channel genes for non-familial BrS patients without SCN5A variants.

    There has been relatively little previous research examining differences between subgroups of child sex offenders. In this study, we compared a group of familial and non-familial child sex offenders attending a community based treatment program on a number of relationship dimensions thought to be important in explaining offending. No statistically significant differences were found between these groups on measures of general empathy, intimacy and loneliness, although non-familial offenders were found to have higher levels of cognitive empathy and a more internal locus of control than familial offenders. These findings are discussed in terms of their possible implications for service delivery.

    Several risk factors for schizophrenia have yet been identified. The aim of our study was to investigate how certain childhood and adolescent risk factors predict the age of onset of psychosis in patients with and without a familial component (i.e. a relative with schizophrenia or schizoaffective disorder). Aside from the age of onset of psychosis, we examined the risk factors for schizophrenia including obstetric complications, birth during winter or spring, behavioral deviances or delayed motor and speech development, exposure to adverse life events and exposure to substance use within a group of 100 patients (45 female, 55 male) with a mean age (± standard deviation) of 35.15 ± 13.21. Birth complications and cannabis abuse are predictors for an earlier onset of schizophrenia in patients with non-familial schizophrenia. No environmental risk factors for an earlier age of onset in familial schizophrenia have been identified. Certain environmental risk factors for schizophrenia seem to have an impact on the age of onset of psychosis in non-familial schizophrenia, they do not seem to have an impact on familial schizophrenia.

    To describe a cohort of bilateral stone formers with significantly different compositions between renal units. Patients treated for bilateral nephrolithiasis over a 4-year period (2007-2010) were identified. Stones were categorized by dominant (≥50%) mineralogical component. Patients with significant compositional differences between renal units (discordant stone formers) were compared to patients with a similar stone type in each kidney. Fifteen of the 59 bilateral stone formers (25.4%) were discordant stone formers with significant differences in stone composition between renal units. Forty-four of the 59 patients (74.6%) had the same stone composition on each side. Thirty percent of discordant stones had calcium phosphate as the dominant stone component. Discordant stone formers were younger, had better renal function, and tended to have a larger stone burden (p < 0.05). A significant minority of bilateral stone formers form a different type of stone in each kidney. Local or micro-environmental etiologies may explain this phenomenon and may also account for failure of preventive therapy in some patients.

    Objective A major focus of implementation science is discovering whether evidence-based approaches can be delivered with fidelity and potency in routine practice. This randomized trial compared usual care family therapy (UC-FT), implemented without a treatment manual or extramural support as the standard-of-care approach in a community clinic, to non-family treatment (UC-Other) for adolescent conduct and substance use disorders. Method The study recruited 205 adolescents (mean age 15.7 years; 52% male; 59% Hispanic American, 21% African American) from a community referral network, enrolling 63% for primary mental health problems and 37% for primary substance use problems. Clients were randomly assigned to either the UC-FT site or one of five UC-Other sites. Implementation data confirmed that UC-FT showed adherence to the family therapy approach and differentiation from UC-Other. Follow-ups were completed at 3, 6, and 12 months post-baseline. Results There was no between-group difference in treatment attendance. Both conditions demonstrated improvements in externalizing, internalizing, and delinquency symptoms. However, UC-FT produced greater reductions in youth-reported externalizing and internalizing among the whole sample, in delinquency among substance-using youth, and in alcohol and drug use among substance-using youth. The degree to which UC-FT outperformed UC-Other was consistent with effect sizes from controlled trials of manualized family therapy models. Conclusions Non-manualized family therapy can be effective for adolescent behavior problems within diverse populations in usual care, and it may be superior to non-family alternatives. PMID:25496283

    Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism. Although many pathogenetic mechanisms have been supposed, none have been proved for certain. Insufficiency fractures of the patellae are rare events and no data has been published on their incidence. We present a case of bilateral fracture of the patellae due to an indirect trauma occurring in an 85-year-old patient affected by Parkinson's disease, osteoporosis and diffuse degenerative osteoarthritis. X-ray of the knees (anteroposterior and lateral) and magnetic resonance imaging evaluation confirmed the fractures. The patient was treated conservatively. She had a good result, returning to her previous autonomous ambulation. This case is unusual because there was no direct trauma to the knees because of bilaterality, but confirmed previous observations about insufficiency fractures of patellae in the presence of comorbidity. Insufficiency fractures of patellae can be an insidious condition in elderly people. Prepatellar pain, a common symptom in the relapse phase of degenerative arthritis of the knee, should not be underestimated, particularly in patients with diseases influencing metabolism of bone and with an elevated risk of fall. A periodical clinical and instrumental follow up should be done in these patient. Moreover, we underline the necessity of a multidisciplinary approach.

    Bilateral unusual coursed ovarian arteries were found in a 45-year-old female cadaver. The ovarian arteries arose from the abdominal aorta at a level inferior to the corpus of L1 vertebra bilaterally. The right ovarian artery was coursing behind the inferior vena cava. The left one was coursing between the left renal artery and vein upward to the level of the inferior part of the body of Th12 vertebra. At the level of Th12 vertebra, it turned caudally and proceeded downward between the anterior-inferior and posterior segmental renal veins. On both sides, ovarian arteries were on their normal routes below the L2 vertebra accompanying the ovarian veins. The variation determined by this study would reduce possible complications of nephrectomy operations that urologists, gynecologists and other related surgeons may encounter.

    In patients presenting with acute renal failure and known/suspected lymphoma, the diagnosis of diffuse renal involvement is important, as there is potential for rapid resolution with chemotherapy. Although FDG is excreted through the kidneys and focal renal disease may be difficult to identify, diffuse renal FDG is more easily recognized and is always abnormal. We report a patient presenting with acute renal failure and suspected lymphoma. F-18 FDG PET/CT study demonstrated diffuse increased FDG uptake in bilaterally enlarged kidneys. Following 1 cycle of chemotherapy, the renal function normalized. An interim F-18 FDG PET/CT demonstrated normal size and FDG uptake within both kidneys.

    An adult, intact male sugar glider ( Petaurus breviceps ) presented for acute caudal abdominal swelling. Treatment by the referring veterinarian included aspiration of urine from the swelling. On physical examination, mild depression, pale mucus membranes, and caudal abdominal swelling were noted. Focused ultrasonographic assessment revealed a fluid-filled caudal abdominal structure and subjective bladder wall thickening. The following day, the sugar glider was severely depressed. Hematology results included hypoglycemia, hyperkalemia, hyponatremia, and azotemia. Ultrasonography revealed bilateral hydronephrosis and hydroureter. Despite supportive care, the animal died. Postmortem examination confirmed bilateral ureteral dilation, renal petechial hemorrhage, and dilation of the right renal pelvis. Submucosal edema, hemorrhage, and lymphoplasmacytic infiltration of the urinary bladder, ureters, and renal pelvises were noted. Hyperplasia of the urinary bladder and ureteral epithelium, coupled with inflammation, may have caused functional obstruction leading to bilateral hydronephrosis and hydroureter. This is the first reported case of hydronephrosis in a marsupial.

    To report a very rare case of bilateral isolated choroidal melanocystosis. Clinical case report and literature review. A 24-year-old asymptomatic African American woman presented with bilateral diffuse choroidal pigmentation. The diagnosis of bilateral isolated choroidal melanocytosis was made, and optical coherence tomography was remarkable for increased choroidal thickness with a normal inner and outer retina. Although extremely rare, bilateral isolated choroidal melanocytosis may occur in young patients, as well as in those who are African American. Longer follow-up of this case and those in the literature will elucidate whether these choroidal lesions enlarge or have a risk of developing uveal melanoma.

    Gas-forming infection of the kidneys can affect either the parenchyma or the collecting system. They are known as emphysematous pyelonephritis (EPN) and emphysematous pyelitis (EP) respectively. Bilateral EPN is a fairly established entity and numerous articles about this condition have been published. However, much less is known about bilateral EP. We report a rare case of bilateral EP and a literature review of this disease. A 66-year-old woman with long-standing bilateral staghorn calculi presented with bilateral EP and severe sepsis. She was treated with antibiotics and bilateral double-J stents to drain the upper urinary tracts. She recovered after 1 month of intensive care and medical therapy. Percutaneous nephrolithotomy (PCNL) had been scheduled to treat her staghorn calculi. A literature search on MEDLINE and Google Scholar with the terms "bilateral emphysematous pyelitis" only found 1 case report in English and another 2 reports in the Korean language that discussed bilateral EP. The collective experience of these few cases, including the present case, suggests that bilateral EP runs a more benign course than bilateral EPN. It should be diagnosed as soon as possible with computed tomography (CT) scans of the renal system. Current evidence shows that can be treated successfully with timely antibiotics. Drainage of the collecting system either percutaneously or with placement of double-J stents might facilitate recovery.

    OBJECTIVE: To analyze the prenatal outcomes in a cohort of fetuses with mild bilateral pyelectasis and determine whether performing serial ultrasounds is a good follow-up strategy. METHODS: A prospective longitudinal study was conducted on 62 fetuses with mild bilateral pyelectasis. Fetal mild bilateral pyelectasis was considered when the renal pelvis measured (in millimeters) ≥5.0 to 10.0, ≥7.0 to 10.0, and ≥10.0 to 15 at ≤23 weeks 6 days, 24 to 31 weeks 6 days, and ≥32 weeks, respectively, with no uretero-calyceal dilatation. Ultrasounds were performed every 3 weeks to assess whether the mild bilateral pyelectasis regressed, remained unchanged (Group 1) or progressed (Group 2). RESULTS: Group 1 consisted of 53 fetuses (85.4%), and progression was observed in 9 cases (Group 2, 14.6%). The initial renal pelvis diameter was significantly larger in fetuses with progression (p=0.028). Statistically significant differences in the renal pelvis diameter were also found at weeks 31 and 35 for both kidneys (p<0.05). The cases requiring intrauterine procedures or early delivery were not observed. CONCLUSION: Fetal mild bilateral pyelectasis with no calyceal dilatation is a benign condition that can be managed in the postnatal period. The initial renal pelvis diameter and the diameter in week 31 or 35 were valuable parameters for identifying cases that would eventually need specific postnatal procedures. PMID:27652832

    Technetium-99m-phosphate compounds used in bone scanning are excreted by the kidney, and excellent renal images can be obtained on routine bone scintigrams. The preoperative bone scans of 49 patients who underwent radical nephrectomy for renal cell carcinoma between 1981 and 1985 were reviewed for renal imaging. Ninety-four percent of the patients had abnormal bone scan renal images (82% had focal decreased uptake, and 12% had focal increased uptake). Six percent of the renal images were symmetrical bilaterally. When bone scans are employed in the postoperative follow-up of patients with renal cancer, they can be used to assess the status of the remaining kidney.

    Most primary severe hypertriglyceridemias (HTGs) are diagnosed in adults, but their molecular foundations have not been completely elucidated. We aimed to identify rare dysfunctional mutations in genes encoding regulators of lipoprotein lipase (LPL) function in patients with familial and non-familial primary HTG. We sequenced promoters, exons, and exon-intron boundaries of LPL, APOA5, LMF1, and GPIHBP1 in 118 patients with severe primary HTG (triglycerides >500 mg/dL) and 53 normolipidemic controls. Variant functionality was analyzed using predictive software and functional assays for mutations in regulatory regions. We identified 29 rare variants, 10 of which had not been previously described: c.(-16A>G), c.(1018+2G>A), and p.(His80Arg) in LPL; p.(Arg143Alafs*57) in APOA5; p.(Val140Ile), p.(Leu235Ile), p.(Lys520*), and p.(Leu552Arg) in LMF1; and c.(-83G>A) and c.(-192A>G) in GPIHBP1. The c.(1018+2G>A) variant led to deletion of exon 6 in LPL cDNA, whereas the c.(-16A>G) analysis showed differences in the affinity for nuclear proteins. Overall, 20 (17.0%) of the patients carried at least one allele with a rare pathogenic variant in LPL, APOA5, LMF1, or GPIHBP1. The presence of a rare pathogenic variant was not associated with lipid values, family history of HTG, clinical diagnosis, or previous pancreatitis. Less than one in five subjects with triglycerides >500 mg/dL and no major secondary cause for HTG may carry a rare pathogenic mutation in LPL, APOA5, LMF1, or GPIHBP1. The presence of a rare pathogenic variant is not associated with a differential phenotype. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

    With the increase in incidence of ectopic pregnancy over the decades, bilateral ectopic pregnancy is also increasing. It is usually associated with assisted reproductive techniques (ART) but in recent years few cases of spontaneous bilateral ectopic pregnancy have been reported. Gynaecologists should be aware of this and that ultrasonography has limitations in diagnosis. In cases of ectopic pregnancy where contralateral adnexa is not clearly identified on ultrasound and fertility needs to be conserved, patient should be managed by experts in well equipped centres. A case of spontaneous bilateral tubal pregnancy that remained undiagnosed till laparotomy, is described.

    Introduction: Unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. However, simultaneous bilateral anterior dislocation of the shoulders is quite rare. Case Presentation: We report a case of a 75-year-old woman presented with simultaneous bilateral anterior shoulder dislocation following a trauma, complicated with a traction injury to the posterior cord of the brachial plexus. Conclusions: Bilateral anterior shoulder dislocation is very rare. The excessive traction force during closed reduction may lead to nerve palsy. Clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. PMID:25685749

    Unstated and unacknowledged bias has a profound impact on the nature and implementation of integrative education models. Integrative education is the process of training conventional biomedical and traditional Chinese medicine practitioners in each tradition such that patient care may be effectively coordinated. A bilateral education model ensures that students in each tradition are cross-taught by experts from the ‘other’ tradition, imparting knowledge and values in unison. Acculturation is foundational to bilateral integrative medical education and practice. Principles are discussed for an open-minded bilateral educational model that can result in a new generation of integrative medicine teachers. PMID:16786060

    The bilateral lateral periodontal cyst is a rare nasological entity, which despite clinical and radiological presentation is being diagnosed by histological characteristics. It is asymptomatic in nature and is observed in routine radiography. The aim and objective of this article is to present a rare case of bilateral lateral periodontal cyst in a 14-year-old child. The clinical and radiographical findings, along with its management have been discussed. Enucleation of bilateral cyst without extraction of the adjacent tooth was performed. Lesion samples were sent for histopathological analysis. The histopathological analysis revealed a thin, non keratinised stratified squamous epithelium resembling reduced enamel epithelium. Epithelial plaques were also seen. A clinicopathological correlation incorporating the surgical, radiographical and gold standard histopathological findings was obtained to suggest the final diagnosis of the bilateral lateral periodontal cyst.

    Familial primary hyperparathyroidism (FPHPT) may occur due to an underlying germ-line mutation in the MEN1, CASR, or HRPT2/CDC73 genes. The disease may be undiagnosed in the absence of a history suggestive of FHPT. Young PHPT patients (≤45 years of age) are more likely to harbor occult FPHPT. A total of 1,161 (136 were ≤45 years of age) PHPT patients underwent parathyroidectomy from 2001 to 2009. Thirty-four patients declined participation. Sixteen patients were diagnosed in the clinical routine with FPHPT (11 MEN1, four MEN2A, and one HPT-JT) and were not included in the genetic analysis. Eighty-six young (≤45 years of age) patients with clinically non-syndromic PHPT underwent genetic analysis. Sanger sequencing of all coding regions of the MEN1, CASR, and the HRPT2/CDC73 genes was performed. Eight of 86 (9.3%) young patients with clinically non-familial PHPT displayed deleterious germ-line mutations in the susceptibility genes (4 MEN1, 3 CASR, and 1 HRPT2/CDC73). There was one insertion, one deletion, two nonsense, and four missense mutations, all predicted to be highly damaging to protein function and absent in 3,244 control chromosomes. Germ-line mutations in known susceptibility genes within young patients with PHPT, including those diagnosed in the clinical routine, was 24/102 (23.5%; 15 MEN1, four RET, three CASR, and two HRPT2/CDC73). We demonstrate that germ-line inactivating mutations in susceptibility genes are common in young patients with clinically non-familial PHPT. Thus, enhanced use of genetic analysis may be warranted in clinically non-familial young PHPT patients.

  3. Echinoderms Have Bilateral Tendencies

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

    This study was designed to investigate the possible role of renal nerves in the regulation of renal function after the application of heat (BH), by means of an electric heating pad (42 +/- 1 degree C) to the skin of the back overlying the kidneys. Both renal efferent (RENA) and renal afferent nervous activity (RANA) were recorded in 7 anesthetized female Wistar rats. It was found that RENA reduced to less than 80% of the control level during 30 min of back heating, accompanied by an increase in excretion of urine, sodium and potassium, and enhanced the glomerular filtration rate. BH in 9 chronic bilateral renal denervated rats (RD) showed the same renal responses as in the renal nerve intact rats (RI) after back heating. It is concluded that renal nerves played only a partially role in the renal diuretic action of back heating.

    Bilaterality is uncommon in Wilms' tumor, being present in 4% to 8% of the cases. We report the combined experience of two children's hospitals in one city over a 20-year period. We encountered nine cases of synchronous bilateral nephroblastoma (National Wilms' Tumor Study 3, stage V). Age at diagnosis ranged from 9 to 41 months (mean 23 months). There were five girls and four boys. Associated findings include nephroblastomatosis in three cases (33%), one of which also had a familial history; undescended testis in two cases; and minor anomalies in two other cases. Surgical treatment consisted of unilateral nephrectomy with contralateral partial nephrectomy or tumorectomy in six cases, nephrectomy with contralateral biopsy only in two cases, and the other patient had bilateral biopsies initially, followed at a later date by partial nephrectomy on one side. All patients received chemotherapy; actinomycin D (AMD) only was used in the oldest case, vincristine and AMD in five cases, to which was added cyclophosphamide in one case and adriamycin in two. Seven patients received radiation therapy. Seven out of the nine patients survived more than 2 years (77%); five are well, off chemotherapy, with no evidence of disease from 4 to 11 years after diagnosis. Two patients suffered from chronic renal failure and one died from complications after renal transplantation more than 19 years after diagnosis. The two patients who died from their disease presented with more advanced tumor. Therefore, the agressiveness of multimodal therapy can be tailored according to stage and histology, and effective chemotherapy allows maximal preservation of renal parenchyma in patients with stage I and II tumors.

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge.

    Simultaneous or subsequent bilateral thalamic haemorrhage is rare, and most reported cases are from Asian countries. An 80-year-old white Cuban man, with a history of arterial hypertension, suffered sudden onset of right hemiparesis. Computed tomography (CT) scan showed a left posteromedial thalamic haemorrhage. Two days later his condition suddenly deteriorated: blood pressure was 220/105 mm Hg, he was stuporous and tetraplegic, respiration was ataxic, and his gaze was fixed and deviated downward and inward. CT scan showed haemorrhages in both thalami, extending to the ventricles. 32 h later the patient died. There are few previous publications of simultaneous or subsequent bilateral thalamic haemorrhages and this is the first report involving a Hispanic patient. Prognosis in patients with bilateral thalamic haemorrhage is poor, and the mechanism underlying the development of subsequent and symmetrical bleeding is not clear. PMID:21709830

  10. The future of renal denervation.

    Esler, Murray; Guo, Ling

    2017-05-01

    The rationale for the renal denervation treatment of severe, drug-resistant essential hypertension remains valid, but the field is now at a procedural watershed. With the commonly flawed procedures of the past, most notably in the Symplicity HTN-3 trial, which typically directed ablating energy into the proximal renal arteries, coupled with the absence of testing for achieved denervation, who could guess which of the past negative renal denervation trials, if any, are valid? But renal denervation procedures will now be different in two important ways. First, energy will be directed into the distal renal arteries and renal artery branches, where the renal nerves lie closest to the artery lumen. The need for this change is emphatic and unequivocal. Second, the number of energy point applications will be increased to 12-16 bilaterally. This is required because local perivascular anatomy distorts energy flow, making it unpredictable, so that multiple overlapping energy doses are needed. Applying these principles in experimental animals achieves near-total renal sympathetic nerve ablation, and lowers blood pressure. The "smart" renal denervation trials of the future will include a sham procedure and 24-h ambulatory blood pressure endpoints, but more important than these, which in comparison is clinical trialist "tinkering", will be the procedural revolution in ablative energy delivery.

    The kidneys are a site of extramedullary leukemic disease that can be readily detected by CT. To demonstrate the spectrum of CT findings in children with renal leukemic involvement. Twelve children were identified retrospectively as having renal leukemic involvement by contrast-enhanced CT of the abdomen. Contrast-enhanced CT images through the kidneys of each patient were reviewed by two pediatric radiologists. Pertinent imaging findings and renal lengths were documented. The electronic medical record was accessed to obtain relevant clinical and pathologic information. Five patients with renal leukemic involvement presented with multiple bilateral low-attenuation masses, while three patients demonstrated large areas of wedge-shaped and geographic low attenuation. Four other patients presented with unique imaging findings, including a solitary unilateral low-attenuation mass, solitary bilateral low-attenuation masses, multiple bilateral low-attenuation masses including unilateral large conglomerate masses, and bilateral areas of ill-defined parenchymal low attenuation. Two patients showed unilateral nephromegaly, while eight other patients showed bilateral nephromegaly. Two patients had normal size kidneys. Two patients had elevated serum creatinine concentrations at the time of imaging. Renal leukemic involvement in children can present with a variety of CT imaging findings. Focal renal abnormalities as well as nephromegaly are frequently observed. Most commonly, renal leukemic involvement does not appear to impair renal function.

    Kidney cancer is the tenth most common cause of cancer death. There are a growing number of genes known to be associated with an increased risk of specific types of kidney cancer. People with Von Hippel-Lindau syndrome have about a 40% risk of developing multiple bilateral clear cell kidney cancers. They can also develop retinal and brain hemangioblastoma, kidneys or pancreas cysts, pheochromocytoma and endolymphatic sac tumor. Four phenotypes with different renal cancer and pheocromocitoma risk have been described depending on the germline mutation. Hereditary papillary renal cell carcinoma syndrome has type 1 papillary renal cell carcinomas associated with protooncogene c-MET germline mutations. Birt-Hogg-Dubé syndrome has FLCN gene mutations associated with fibrofolliculomas, lung cysts with a high risk for spontaneous pneumothorax, and a 15% to 30% risk of kidney cancer (most classified as chromophobe carcinoma, oncocytoma or oncocytic hybrid, but clear cell and papillary kidney cancers have also been reported). Histopathological findings such as oncocytosis and oncocytic hybrids are very unusual outside the syndrome. Hereditary leiomyomatosis and renal cell cancer syndrome shows mutations of Fumarate hydratase gene and cutaneous leiomyomata in 76% of affected individuals, uterine leiomyomata in 100% of females, and unilateral, solitary, and aggressive papillary renal cancer in 10 to 16% of patients. A specific histopathological change is eosinophilic prominent nucleoli with a perinucleolar halo. Tuberous sclerosis complex is one of the most prevalent (1/5.800) hereditary syndromes where renal disease is the second leading cause of death, associated with angiomyolipomas (70%), renal cysts, oncocytomas or clear cell cancer.

  14. Bilateral leg edema in an older woman.

    2015-01-01

    Bilateral leg edema is a frequent symptom in older people and an important concern in geriatric medicine. Further evaluation is frequently not performed and simple therapy with diuretics is prescribed. Particularly in older patients, long-term use of diuretics can lead to severe electrolyte imbalances, volume depletion, and falls. In this case report we want to focus the physicians' attention on the necessity to determine the cause and show a correspondingly effective treatment for bilateral leg edema in older people. A thorough approach is required to recognize diseases and to avoid adverse drug events as geriatric patients often show an atypical presentation or minor symptoms. The cause of swollen legs is often multifactorial; therefore, the patient's individual history and an appropriate physical examination are important. Depending on the clinical symptoms, evaluation including basic laboratory tests, urinalysis, chest radiography, and echocardiogram may be indicated. The most probable cause of bilateral edema in older patients is chronic venous insufficiency. Heart failure is also a common cause. Other systemic causes such as renal disease or liver disease are much rarer. Antihypertensive and anti-inflammatory drugs can frequently cause leg edema, but the incidence of drug-induced leg swelling is unknown. With the help of this special case we tried to develop an approach to the diagnosis of symmetric leg edema in older patients, a problem frequently neglected in geriatric medicine.

  15. Urolithiasis associated with bilateral pelvic diverticula: a case report.

    We present a case of renal stone associated with bilateral pelvic diverticula. The initial diagnosis by ultrasonography and plain abdomen radiography (KUB) was urolithiasis with a 15-mm calculus in the right renal pelvis. The patient was referred for extracorporeal shock wave lithotripsy, but no stone fragments were yielded. So, further evaluations were performed by using repeated ultrasonography, intravenous urography, and computerized tomography, which revealed the presence of diverticula in both right and left renal pelvises with stone fragments within the right sided diverticulum. We concluded that intravenous urography and contrast-enhanced computerized tomography are essential for confirmation of diagnosis when ultrasonographic findings suggest the presence of renal cystic lesions, or when stone fragments are not yielded after extracorporeal shock wave lithotripsy.

  16. Bilateral cleft lip.

    The surgeon's objectives are normal nasolabial appearance and normal speech. The principles for synchronous repair of bilateral cleft lip have been established, and the techniques continue to evolve. Primary repair impairs maxillary growth, but little can be done at this time except to practice gentle craftsmanship and to minimize tension on the lower labial closure. The cutaneous lip should never be reopened for revision, and the number of secondary procedures involving the nasal cartilages should be kept to a minimum. Many adolescents with repaired bilateral cleft lip need maxillary advancement to improve projection of the nasal tip, to protrude the upper lip, and to attain normal sagittal skeletal harmony. With expected improvements in the technology of distraction osteogenesis, maxillary advancement may someday become as acceptable as orthodontic treatment.

    Congenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3-year-old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well.

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor.

    To investigate the effect of renal denervation (RDN) on blood pressure and renal function in refractory hypertension after renal artery recanalization and optimal medical therapy. Ten patients (6 women; mean age 70.0±5.1 years) with an office systolic blood pressure >160 mmHg despite taking ≥3 antihypertensive drugs and uni- or bilateral renal artery stenting were treated with RDN. Radiofrequency (RF) energy was delivered to the native segment of the artery keeping a 5-mm safe distance from the stented segments. Standardized office (OBP) and ambulatory (ABP) blood pressure measurements, medication, and renal assessment, including renal duplex ultrasound and renal function, were determined at baseline and on follow-up to 12 months. OBP (systolic/diastolic) at baseline was 190.0±20.4 / 84.2±10.1 mmHg. It decreased to 171.1±28.7* / 82.2±8.7, 165.5±28.4(†) / 76.1±7.4, and 158.3±14.2(†) / 75.5±9.5(†) mmHg (*p<0.001; (†)p<0.01) at 3, 6, and 12 months after RDN, respectively. Average ABP (systolic/diastolic) after 6 and 12 months decreased by -7.6(‡) / -3.1 and -11.3(‡) / -5.1(‡) mmHg ((‡)p<0.05). There was no renal artery (re)stenosis, dissection, or aneurysm within 12 months. Creatinine, cystatin C, and glomerular filtration rate remained unchanged. Urine albumin excretion decreased in 4/10 patients. Renal resistive indices improved in native, but not in stented renal arteries within the follow-up period. This proof-of-concept study demonstrates that RF-based RDN can be safely and effectively delivered in patients with resistant hypertension and previous renal artery stenting.

    1987-02-01

    The renal overflow of norepinephrine (NE) and dopamine (DA) to plasma from the innervated kidney was studied at rest and during sympathetic nervous system activation by bilateral carotid artery occlusion (BCO) in vagotomized dogs under barbiturate or barbiturate/nitrous oxide anesthesia. BCO elevated arterial pressure and the arterial plasma concentration of NE, DA, and epinephrine (Epi). Renal vascular resistance (renal arterial pressure kept constant) increased by 15 +/- 7% and the net renal venous outflows (renal veno-arterial concentration difference x renal plasma flow) of NE and DA were enhanced. To obtain more correct estimates of the renal contribution to the renal venous catecholamine outflow, they corrected for the renal extraction of arterial catecholamines, assessed as the extractions of (/sup 3/H)NE, (/sup 3/H)DA, or endogenous Epi. The (/sup 3/H)NE corrected renal NE overflow to plasma increased from 144 +/- 40 to 243 +/- 64 pmol-min/sup -1/ during BCO, which, when compared with a previous study of the (/sup 3/H)NE corrected renal NE overflow to plasma evoked by electrical renal nerve stimulation, corresponds to a 40% increase in nerve impulse frequency from approx. 0.6 Hz. If the renal catecholamine extraction was not taken into account the effect of BCO was underestimated. The renal DA overflow to plasma was about one-fifth of the NE overflow both at rest and during BCO, indicating that there was no preferential activation of noradrenergic or putative dopaminergic nerves by BCO.

    Benign infantile seizures [BIS], familial and non-familial, represent a benign, age-related idiopathic syndrome of infancy. The aim of the current paper is to document the presence of the syndrome in Saudi Arabia and in Arab populations and to discuss the characteristic electroclinical features and the benign nature of this syndrome. A case series of 275 patients with epileptic seizures (age range: 2 months-13 years) were followed over a period of 3 years and 7 months. The inclusion criteria for BIS were as follows (1) age of seizure onset between 2 and 24 months, (2) normal development before, during and after the onset of seizures, (3) normal interictal EEG, (4) normal brain imaging, and (5) good response to treatment. We analyzed these infants with respect to age at seizure onset, sex, physical and neurological examination, consanguinity, frequency and type of convulsions, associated conditions and laboratory and radiological investigations. A waking and sleeping interictal EEG was performed on all patients, and for one patient (No. 1), ictal EEG and video clips were recorded. Fourteen infants (12.0%) showed electroclinical features consistent with BIS. Eleven patients fulfilled the criteria of benign non-familial infantile seizures (BNFIS), and for three patients, their family pedigrees showed the possibility of benign familial infantile seizures (BFIS). All of the patients responded to anti-epileptic treatment, and 50% of them responded within 3 months. To our knowledge, this is the first study to document the presence of BIS (Fukuyama-Watanabe-Vigevano syndrome) in Saudi Arabian and Arab populations. We highlighted the characteristic features of BIS and demonstrated the benign nature of the syndrome. Copyright 2009 Elsevier B.V. All rights reserved.

    Cherubism is a rare familial disease that occurs between the ages two and five years and regresses after puberty. Most of the cherubism cases show familial history, but there are some cases without familial histories of disorder. A two-year-old boy with a painless symmetrical progressive swelling of the jaws had visited maxillofacial radiology department. Panoramic radiograph revealed well-defined multilocular, radiolucent areas of both jaws. Computed tomography of the jaws showed well-defined, bilateral, multilocular, expansile lesions with thinning of cortical plate of maxilla and mandible and displacing the unerupted first molar anteriorly. Clinical, radiologic, and histopathologic characteristics confirmed the diagnosis of cherubism. PMID:28105052

    A 63-year old male was referred to our emergency unit due to acute renal failure. The level of serum renal function tests levels, blood urea nitrogen (BUN)/creatinine, were 63 mmol/L/848 μmol/L. CT (Computarised Tomography) scan showed a huge bladder stone (5 cm x 6 cm x 5 cm) with increased bladder wall thickness. Post-renal acute renal failure due to bilateral ureterohydronephrosis was diagnosed. The huge bladder stone was considered to be the cause of ureterohydronephrosis and renal failure. The patient was catheterised and received haemodialysis immediately. He received haemodialysis four times during ten days of hospitalization and the level of serum renal function tests levels (BUN/ creatinine) decreased 18 mmol/L/123 μmol/L. After improvement of renal function, we performed cystoscopy that demonstrated normal prostatic urethra and bladder neck and bilaterally normal ureteral orifices. Bladder wall was roughly trabeculated and Bladder outlet was completely obstructed by a huge bladder stone. After cystoscopy open, cystolithotomy was performed to remove calcium phosphate and magnesium ammonium phosphate stone weighing 200 g removed. Four days after operation the patient was discharged uneventfully and urethral catheter was removed on the seventh day. Post-renal acute renal failure due to large bladder stones is rare in literature. According to the our knowledge; early diagnosis of the stone avoid growth to large size and prevent renal failure.

    It is the purpose of this report to focus attention on the clinical usefulness of Renal Duplex for the diagnosis of patients with vasculo-renal diseases in terms of: 1. Accuracy of Duplex/Angiography in the measurement of the renal stenosis degree. 2. Correlationship between Duplex ans Isotopic Renogram with respect to the study of the parenchyma's perfusion. 3. The effect of the inhibitors of the conversor enzyme (Captopril) on the Doppler signal of the parenchyma, comparing it with the results from the captopril test about the peripheral plasmatic renin activity and the isotopic renogram, in patients with vasculo-renal HTA. Results obtains by Duplex and Angiography were compared in 92 renal arteries from 46 patients. For both technics, three degrees of stenosis were established: 0-59%, 60-99% and occlusion. The Duplex technique identified 49/54 stenosis < 60%, 28/33 stenosis > 60% and 5/5 occlusions (Kappa 0.8). Sensibility and specificity of Duplex for the diagnosis of stenosis > 60% were, respectively, 89.5% and 90.7%; with an exactness of 90.2%. The angiographies showed stenosis > 60% in 23 patients with HTA (diastolic pressures > 100 mmHg). In all of the patients, a measurement of the plasmatic renin activity, an isotopic renogram and a Doppler of the interlobar arteries basal and post-captopril, were performed. The correlationship between Duplex and isotopic renogram with respect to the measurement of the relative renal perfusion was statistically significant (r = 0.91; p < 0.0001). The captopril test for renin and isotopic renogram were positives for 5 patients (4 with unilateral stenosis an 1 with bilateral stenosis). All of them showed severe stenosis (> 80%).(ABSTRACT TRUNCATED AT 250 WORDS)

    The option of nephron sparing surgery for unilateral Wilms tumor has been debated in the recent literature. This procedure is being used increasingly to preserve kidney tissue and function. However, nephron sparing surgery is feasible only for selected cases, and a higher local relapse rate has been observed. Moreover, a significant reduction of nephrons is associated with development of renal hypertension and progressive renal failure. We analyzed outcomes after bilateral partial nephrectomy and unilateral partial plus contralateral total nephrectomy in patients with bilateral Wilms tumor. We analyzed data from the Society of Pediatric Oncology and Hematology database on 22 patients with bilateral Wilms tumor. Kidney size was measured using volumetric analysis of magnetic resonance imaging. Patients were matched with children who had undergone magnetic resonance imaging of the abdomen for other malignancies. Mean kidney volumes after unilateral partial plus total contralateral nephrectomy (66.9 cm(3)) were significantly greater than the reference kidneys (p = 0.028), whereas controls were equal to the bilateral partial nephrectomy group (49.7 cm(3), p = 0.959). Total kidney volume was significantly larger after bilateral partial nephrectomy (102.1 cm(3)) vs unilateral partial plus total contralateral nephrectomy (66.9 cm(3), p = 0.0338). Eight patients (66.7%) had renal hypertension after unilateral partial plus total contralateral nephrectomy but only 2 (20%) after bilateral partial nephrectomy (p = 0.043). Overall survival and relapse rates were equal between the groups and did not correlate with unfavorable histology. Our findings suggest that patients with bilateral Wilms tumor benefit from bilateral nephron sparing surgery. Hypertension is less common after bilateral partial nephrectomy, and rates of local relapse or disease associated death are distributed equally between the groups.

    A 55-year-old woman underwent bilateral renal artery stent placement with good angiographic result. After the procedure, the patient complained of left flank pain secondary to subcapsular hematoma. Retrospective evaluation of images taken during stent implantation favored the diagnosis of guidewire perforation. Three hours after the procedure, contrast-enhanced computed tomography and subsequent renal angiography showed multifocal extravasations. We performed emergent renal ablation for the treatment of massive bleeding. To our knowledge, this is the first use of transcatheter renal ablation technique for this purpose.

    In an attempt to identify a feline model of acute or chronic kidney disease, this study was designed to evaluate the effects of 15 or 30 min of bilateral renal ischemia (RI) and 60 min of unilateral RI with delayed contralateral nephrectomy as models of acute kidney injury and chronic interstitial fibrosis in cats. Adult, purpose-bred, USDA Class A cats (n = 14) were randomly assigned to receive bilateral RI for 15 min (n = 3) or 30 min (n = 3), unilateral RI for 60 min with a delayed (2 wk) contralateral nephrectomy (n = 5), or sham unilateral RI with a delayed contralateral nephrectomy (n = 3). Serum creatinine concentration, urine specific gravity, and plasma clearance of iohexol were assessed at several time points throughout the study. Renal interstitial inflammatory cell counts and descriptive histopathology were acquired in all cats. Histomorphometry was used to quantify renal interstitial fibrosis and collagen at 120 d after RI in cats undergoing unilateral RI. Renal histopathology was evaluated at 21 and 120 d after bilateral and unilateral RI, respectively. Neither duration of bilateral RI resulted in appreciable histologic renal damage at 21 d after ischemia. At 120 d after ischemia, variable amounts of renal fibrosis were noted after 60 min of unilateral RI with delayed contralateral nephrectomy. Neither of the tested methods is a suitable model of consistent renal interstitial fibrosis in cats. Healthy cats appear able to sustain bilateral RI for as long as 30 min with no apparent effects on renal morphology or function at 21 d after ischemia. PMID:28222840

    2008-06-01

    Renal tract malformations are congenital anomalies of the kidneys and/or lower urinary tract. One challenging feature of these conditions is that they can present not only prenatally but also in childhood or adulthood. The most severe types of malformations, such as bilateral renal agenesis or dysplasia, although rare, lead to renal failure. With advances in dialysis and transplantation for young children, it is now possible to prevent the early death of at least some individuals with severe malformations. Other renal tract malformations, such as congenital pelviureteric junction obstruction and primary vesicoureteric reflux, are relatively common. Renal tract malformations are, collectively, the major cause of childhood end-stage renal disease. Their contribution to the number of adults on renal replacement therapy is less clear and has possibly been underestimated. Renal tract malformations can be familial, and specific mutations of genes involved in renal tract development can sometimes be found in affected individuals. These features provide information about the causes of malformations but also raise questions about whether to screen relatives. Whether prenatal decompression of obstructed renal tracts, or postnatal initiation of therapies such as prophylactic antibiotics or angiotensin blockade, improve long-term renal outcomes remains unclear.

    Bilateral dense rings in the renal medulla were found on noncontrasted computed tomography in a patient with marked hypercalcemia and suspected primary hyperparathyroidism. The rings were not present on plain radiographs and were obscured on contrasted scans, and may represent occult nephrocalcinosis. Associated findings--renal insufficiency induced by hypercalcemia and interstitial nephritis--may be reversible with early recognition of this CT finding.

    An experience with 216 bilateral hernias in female patients is reviewed. The condition is rare, occurring only once in every 250 patients admitted for a hernia repair. Bilateral primary indirect inguinal hernias were the most frequent type. Bilateral primary femoral hernias were quite rare while bilateral primary direct inguinal hernias were even more uncommon. Other rare bilateral combinations are briefly described. The incidence in children is given. Etiological factors are discussed, emphasizing the strong posterior wall of the inguinal canal in females. Two per cent of patients developed a recurrent hernia; one per cent of hernias recurred. No recurrence following a bilateral primary indirect inguinal hernia repair and no “femoral” recurrence following inguinal repair were recorded. PMID:5348491

    Summary Background To evaluate the safety, etiology and outcomes of patients undergoing bilateral thoracentesis. Methods This is a prospective cohort study of 100 consecutive patients who underwent bilateral thoracenteses in an academic medical center from July 2009 through November 2010. Pleural fluid characteristics and etiologies of the effusions were assessed. Mean differences in levels of fluid characteristics between right and left lungs were tested. Associations between fluid characteristics and occurrence of bilateral malignant effusions were evaluated. The rate of pneumothorax and other complications subsequent to bilateral thoracentesis was determined. Results Exudates were more common than transudates, and most effusions had multiple etiologies, with 83% having two or more etiologies. Bilateral malignant effusions occurred in 19 patients, were the most common single etiology of exudative effusions, and were associated with higher levels of protein and LDH in the pleural fluid. Among 200 thoracenteses performed with a bilateral procedure, seven resulted in pneumothoraces, three of which required chest tube drainage and four were ex vacuo. Conclusions More often than not, there are multiple etiologies that contribute to pleural fluid formation, and of the combinations of etiologies observed congestive heart failure was the most frequent contributor. Exudative effusions are more common than transudates when bilateral effusions are present. Malignancy is a common etiology of exudative effusions. This study suggests that the overall complication rate following bilateral thoracentesis is low and the rate of pneumothorax subsequent to bilateral thoracentesis is comparable to unilateral thoracentesis.

    Hypertension is common in renal transplant patients and sometimes very difficult to control. Refractory hypertension can adversely affect renal graft and patient survival. Many antihypertensive medications are not well tolerated or can have important drug interactions with immunosuppressive medications. These drugs can cause significant side effects including fluid depletion, azotemia, electrolyte imbalance, and anemia. Bilateral native nephrectomy in renal transplant patients has been reported to be beneficial in controlling severe hypertension. We report five patients with severe hypertension despite as many as 9 different antihypertensive medications. All patients had previous kidney or simultaneous kidney pancreas transplantation. Each of our patients underwent laparoscopic bilateral native nephrectomy. Renal function varied from creatinine of 1.4–2.4, and the number of antihypertensive medications from 3 to 9 at the time of nephrectomy surgery. Mean arterial blood pressure improved in all five patients at 3–6 months post nephrectomy, the number of antihypertensive medications decreased in 4, but renal function remained stable at 3–6 months in only 3 patients. We found laparoscopic bilateral native nephrectomy to be beneficial in renal and simultaneous kidney pancreas transplant patients with severe and refractory hypertension. Our patients with better baseline renal allograft function at time of nephrectomy received the most benefit. No decrease in allograft function could be attributed to acute rejection. PMID:26348394

    Perinephric lymphangioma is rare disorder that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic tissue to establish normal communication with the rest of lymphatic system. Once there is restricted drainage of lymphatic fluid the lymphatic channels dilate to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally .This condition presents with various signs and symptoms or can be just an incidental finding which in presence of misleading clinical history may be confused with other diseases. CT scan with delayed cuts and USG guided aspiration with biochemical analysis of fluid will help us in arriving to final diagnosis.

In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

    A 52-year-old Mexican man presented with asymptomatic, bilaterally symmetrical lipid infiltrates of the cornea and adjacent limbus. No evidence of previous ocular disease or systemic disorder of lipid metabolism could be detected. Penetrating keratoplasty of the right eye was required. The cornea was rigid and thick, with posterior bulging into the anterior chamber. Light microscopy revealed deep corneal lipid granules, foamy histiocytes, vascularisation, and chronic non-granulomatous inflammation. Transmission electron microscopy showed extracellular lipid spaces and numerous intracytoplasmic lipid vacuoles in histiocytes, keratocytes, conjunctival epithelium, and the endothelium of blood vessels in the corneal stroma and adjacent limbal conjunctiva. Histochemical analysis revealed the presence of neutral fats, free fatty acids, cholesterol, and phospholipids. Images PMID:3395592

    The authors report four patients with a syndrome of painless bilateral isolated phrenic neuropathy. Electrophysiologic testing demonstrated active denervation restricted to the diaphragm. Long-term recovery was poor. The authors conclude that bilateral isolated phrenic neuropathy is a cause of painless diaphragmatic paralysis distinguishable from immune brachial plexus neuropathy and other neuromuscular disorders with similar clinical presentation.

    Renal sympathetic nerve activity has an important role in renal disease-associated hypertension and in the modulation of fluid homeostasis. In the present study, changes in renal function and renal sodium/potassium handling were investigated in groups of 12-week-old male, spontaneously hypertensive rats with renal denervation (RDNX group) or sham denervation (sham group). The RDNX group excreted significantly more sodium than the sham group during the 2-week observation period (P<0.05). Following bilateral renal denervation, the fractional lithium excretion was elevated in the RDNX group compared with the sham group, but no significant effect was observed of renal denervation on the fractional distal reabsorption rate of sodium or the fractional excretion of potassium. Furthermore, the glomerular injury score and the wall-to-lumen ratio of the interlobular artery were significantly lower in the RDNX group than in the sham group (P<0.05). In conclusion, the present study indicates an involvement of the renal sympathetic nerves in the regulation of renal tubular sodium reabsorption in spontaneously hypertensive rats and in the renal damage associated with hypertension.

    2017-01-01

    Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex. Pelviureteric junction obstruction, benign prostatic hypertrophy, urethral stricture, neurogenic bladder, retroperitoneal mass and bladder outlet obstruction are some of the frequent causes of hydroureteronephrosis in adults. The incidence of non-calculus hydronephrosis is more common in males than in females. Ultrasonography is the most important baseline investigation in the evaluation of patients with hydronephrosis. Here, we report a rarely seen case of bilateral hydroureteronephrosis associated with a hypertrophied, trabeculated bladder in an adult male cadaver, suspected to be due to a primary bladder neck obstruction, and analyse its various other causes, clinical presentations and outcomes.

    Amelogenesis imperfecta (AI) is a group of hereditary disorders that affect the quality and/or quantity of dental enamel. This paper describes the clinicopathological features of a patient who was born of nonconsanguineous parents and who presented with oral alterations, including yellow and misshapen teeth, intrapulpal calcifications, delayed tooth eruption, and gum enlargement. Scanning electron microscopy of the teeth revealed hypoplastic enamel, and a renal ultrasound detected bilateral nephrocalcinosis, leading to a diagnosis of AI and nephrocalcinosis syndrome. Since nephrocalcinosis is often asymptomatic and can be associated with impaired renal function, dentists who see children with a generalized and thin hypoplastic AI should consider a renal ultrasound scan and referral to a Nephrologist. Children with nephrocalcinosis should also be considered for a dental check.

    1983-05-01

    Visualization of Ga-67 citrate in the kidneys at 48 hours and 72 hours post injection is usually interpreted as evidence of renal pathology. In reviewing approximately 200 consecutive patients referred for gallium scans, 40 patients who also underwent liver/spleen Tc-99m sulfur colloid (SC) studies within one month of the gallium study were identified. Fourteen of these patients showed advanced hepatocellular dysfunction on the Tc-99m SC liver/spleen images. Of these 14 patients, nine had persistent renal accumulation of gallium at 48 or 72 hours. Five of these nine patients had no evidence of primary renal disease by clinical or postmortem examination and subsequent clinical information indicated that two additional patients probably had no significant renal pathology. Therefore, bilateral symmetrically increased renal uptake of gallium in patients with advanced hepatocellular disease should not necessarily be interpreted as evidence of renal pathology.

    Nowadays most renal disorders, especially urinary tract malformations and renal cystic disease, are diagnosed antenatally. In cases of severe bilateral disease, intrauterine renal dysfunction may lead to renal oligohydramnios (ROH), resulting in pulmonary hypoplasia which affects perinatal mortality and morbidity as well as the long-term outcome. However, some infants may only have mild pulmonary and renal disease, and advances in postnatal and dialysis treatment have resulted in improved short- and long-term outcome even in those infants with severe ROH. Here, we review the current state of knowledge and clinical experience of patients presenting antenatally with severe bilateral renal disorders and ROH. By addressing underlying mechanisms, intrauterine tools of diagnosis and treatment as well as published outcome data, we hope to improve antenatal counselling and postnatal care. KEY SUMMARY POINTS: 1. Nowadays most renal disorders are diagnosed antenatally, especially urinary tract malformations and renal cystic disease. 2. Severe kidney dysfunction may lead to renal oligohydramnios, which can cause pulmonary hypoplasia and is a risk factor of perinatal mortality and postnatal renal outcome. However, as considerable clinical heterogeneity is present, outcome predictions need to be treated with caution. 3. Advances in postnatal and dialysis treatment have resulted in improved short- and long-term outcomes even in infants with severe renal oligohydramnios. 4. A multidisciplinary approach with specialist input is required when counselling a family with an ROH-affected fetus as the decision-making process is very challenging.

    The ureterocele is an uncommon congenital anomaly of the lower ureter. Ureterocele with a single pelvicalyceal system, bilateral, and orthotopic variety is less common. Calculi within bilateral ureterocele are a rare occurrence. To the best of our knowledge, only a few similar cases have been reported in the literature. Among the all reported presentations of this type of ureterocele, presentation with Acute Urinary Retention (AUR) has not been described in the literature. We present a case of nine-year-old child having bilateral, single system orthotopic ureterocele with calculi in bilateral ureterocele and presented with AUR due to obstructive bulbar urethral calculus. The bilateral endoscopic incision was given and all four calculi were removed endoscopically through percutaneous route. Voiding cystourethrography after two years follow-up was non-refluxing. The purpose of reporting this case is the rarity of the disease and to emphasize that delay in diagnosis and treatment of these cases may lead to complications such as recurrent urinary tract infection and renal failure.

    A kidney transplantation was performed in July 1981 on a 29 year old woman who presented the signs of tuberous sclerosis and suffered from chronic renal failure. The frequency and the genetic transmission of Bourneville's disease are explained. The signs of the disease are exposed with special emphasis on the renal lesions. Only the patients with minor neurological symptoms can survive. These patients are able to develop chronic renal failure. This occurs either when the kidneys are destructed by renal cysts or tumors, or when a bilateral nephrectomy must be performed for bleeding or tumoral compression. A kidney transplantation can give them an opportunity to live almost normally. When nephrectomy is not performed, a regularly follow-up is necessary because the unknown future of the renal lesions in place.

    We report the successful treatment of a patient that presented with bladder tumor, bilateral multiple renal stones, right lower ureteral stone, and bilateral hydroureteronephrosis with progressively rising serum creatinine. Initially, he was managed by drainage of the upper tract by left percutaneous nephrostomy tube until serum creatinine dropped to normal value then he was managed by radical cystectomy and orthotopic bladder substitution. Three weeks later, he was subjected to simultaneous bilateral multi-puncture tubeless percutaneous nephrolithotomy. In addition, we report on the feasibility of opacification of the collecting system via ascending pouchogram by direct passage of the dye through the directly implanted ureters thus avoiding intravenous contrast injection.

    Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 10⁹/L, hemoglobin 8.7 g/dL and platelet count 197 × 10⁹/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

  18. Bilateral cochlear implantation: current concepts.

    PubMed

    2009-10-01

    The goal of this review is to examine the most recent literature exploring the indications, outcomes, and long-term benefit of bilateral cochlear implantation in children and adults. The indications for cochlear implantation have expanded, as many unilaterally implanted individuals are able to achieve open-set word recognition. Despite the benefits seen in unilateral implantation, many individuals have difficulty perceiving speech in noisy environments. Bilateral cochlear implantation has made great strides in providing individuals access to sound information from both ears, allowing improved speech perception in quiet and in noise, as well as sound localization. Recently, the House Cochlear Implant study group released a position statement in which the group strongly endorsed bilateral cochlear implantation. Improved speech perception in quiet has also been demonstrated by many groups with bilateral implantation. Improved sound localization abilities have been shown to be dependent on interaural level differences. The binaural benefits of head shadow and summation have been long shown in bilaterally implanted individuals. Recently, a growth in squelch has been seen in these individuals likely as a result of increased experience with both implants. This may indicate neural integration of the inputs over time. The literature supports the binaural benefit of bilateral cochlear implantation with demonstrated improved speech perception outcomes in quiet and in noise, sound localization data, and subjective benefits.

    Introduction Prostatic hyperplasia is the most frequent tumor in men older than 50 years of age. Bilateral hydronephrosis secondary to benign prostatic hypertrophy is a rare condition most often due to vesicoureteral reflux. Herein we report a case of a patient with bilateral hydronephrosis with distal ureter obstruction caused by detrusor hypertrophy due to prostatic hyperplasia, our analysis of the clinical data and a review of the relevant published literature. Case presentation We report a case of a 65-year-old Berber man with clinically significant storage, bladder-emptying symptoms and bilateral low back pain with renal biologic failure and bilateral ureterohydronephrosis, distal ureteral stenosis, detrusor hypertrophy and prostate hyperplasia without significant post-void residual urine volume visualized by abdominal sonography. The patient underwent bilateral JJ stent insertion with transurethral resection of the prostate. The patient was discharged 3 days after surgery without any obvious complications. At his 3-month follow-up examination, the JJ stent was removed and the patient had comfortable urination without renal failure. Conclusion This is an extremely rare condition that has important diagnostic considerations because of the possibility of comorbid severe obstructive uropathy and chronic renal failure.

    Simple renal cyst is the most common cystic deformation found in adults. However, there were a few systematic Korean reports for the clinical symptoms and complications of simple renal cysts. The author's purpose was to determine the relationship between simple renal cysts diagnosed by abdominal ultrasonography and hypertension. Among 13,482 persons who took a routine physical examination at Ulsan University Hospital in 2002, 5,127 persons who took medical examinations again in 2010 were selected. We excluded persons who had renal cyst, hypertension, diabetes, liver cirrhosis, kidney disease, thyroid disease, and cancer in 2002. Analysis was conducted for 505 subjects with newly diagnosed simple renal cyst and 2,744 subjects without renal cyst in 2010. The simple renal cyst group was compared to a control group without renal cyst. Among 3,249 subjects, simple renal cyst and hypertension were newly diagnosed in 505 subjects and 503 subjects. The subjects who had simple renal cysts had significantly higher hypertension incidence (odds ratio [OR], 1.53; 95% confidence interval [CI], 1.20 to 1.94). Significant hypertension incidence was observed especially when the subjects had cysts located on both kidneys (OR, 3.48; 95% CI, 2.12 to 5.71), two (OR, 3.08; 95% CI, 1.84 to 5.15) or more cysts (OR, 3.12; 95% CI, 1.38 to 7.04), and larger cysts more than 1 cm in diameter (OR, 1.55; 95% CI, 1.16 to 2.07). The presence of simple renal cysts was significantly positively related to the incidence of hypertension. Bilateral distribution, two or more number, and larger size than 1 cm diameter were the characteristics of simple renal cyst related to hypertension.

    Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over. We considered pediatric cases of ureteral obstruction presenting as bilateral, along with some cases which truly appeared as single-sided, because of their potential bilateral presentation. We performed a review of the literature by a search on PubMed, CrossRef Metadata Search, internet and reference lists of single articles updated to May 2014, with no time limits in the past. Given that we deal with rare conditions, we decided to include also papers in non-English languages, published with an English abstract. For the sake of clearness, we divided our research results into 8 categories: (1) urolithiasis; (2) congenital urinary tract malformations; (3) immuno-rheumatologic causes of ureteral obstruction; (4) ureteral localization of infections; (5) other systemic infective causes of ureteral obstructions; (6) neoplastic intrinsic ureteral obstructions; (7) extrinsic ureteral obstructions; and (8) iatrogenic trigonal obstruction or inflammation. Of course, different pathogenic mechanisms underlay those clinical pictures, partly well-known and partly not completely understood. PMID:25374811

    We report a case of Inflammatory Abdominal Aortic Aneurysm (IAAA) producing bilateral hydro-ureteronephrosis. A 74-year-old patient presented to urologist office for bilateral hydronephrosis detected by kidney and bladder ultrasound (US). Patient reported lower urinary tract symptoms and inconstant and slight low back pain irradiated to inguinal region dating 3 weeks. Renal function, urine analysis and abdominal examination were normal. However the repeated ultrasound in the urologist office revealed abdominal aortic aneurism extended to iliac vessels. The patient was sent directly to vascular surgery unit where contrast computerized tomography (CT) and successful surgical repair were done. Final diagnosis was IAAA. The post-operative course was uneventful. Renal function was regular and the hydronephrosis reduced spontaneously under monitoring by CT and US. We review diagnosis and management of hydronephrosis that is sometimes linked to IAAA rather than standard AAA. Abdominal ultrasound is mandatory in any bilateral hydronephrosis and it could save lives.

    Nephron-sparing surgery (NSS) has been proposed by many as an alternative to bilateral nephrectomies and renal replacement therapy in bilateral Wilms’ tumor (BWT). NSS is not without significant recurrence, morbidity, and mortality. Long-term follow-up, especially with regard to the renal function, remains lacking. Preoperative computed tomography angiogram can help prepare a roadmap for NSS but can underestimate the salvageable parenchyma due to compression of normal adjacent parenchyma. Intraoperative ultrasound can delineate the boundary of surgical margin and help achieve negative margins. We present two cases of BWT, aged 7 and 13 months, managed with neoadjuvant chemotherapy followed by bilateral NSS and adjuvant chemotherapy and report the follow-up of the same. We also explore the role of preoperative imaging and intraoperative ultrasound in the management. Both patients are alive without recurrence at a follow-up of 12 and 8 months. PMID:28057999

  10. Pre- and postoperative evaluation of renal function in patients with staghorn calculi utilizing quantitative renal scanning.

    Differential quantitative renal scans using 99-technetium diethylene triaminepentaacetic acid (DTPA) or 131I Hippuran were obtained properatively on 12 patients with unilateral or bilateral staghorn calculi. Of the 14 renal units studied, 12 kidneys underwent anatrophic nephrolithotomy, pyelolithotomy, or a combination of both techniques; 2 patients underwent nephrectomy based on poor function of the affected side preoperatively. Postoperative follow-up scans were obtained on the 12 kidneys undergoing stone cleanout. Seven of 12 kidneys (58 per cent) studied pre- and postoperatively showed moderate to significant improvement in per cent contribution to total renal function. Seven of 10 kidneys (70 per cent) studied pre- and postoperatively showed improvement in glomerular filtration rate or effective renal plasma flow. The scans revelaed no dramatic difference in postoperative functional loss between pyelolithotomy and anatrophic nephrolithotomy. The computerizewd quantitative renal scan helps in selection of surgical technique and objective postoperative assessment of surgical results.

    1999-03-01

    To report experience in patients with Kallmann syndrome (KS) in whom urography was used to establish the type and frequency of renal anomalies associated with the disorder. Of 19 patients with KS, 15 had the X-linked recessive form of the disease, whereas the remaining four were sporadic. Each patient underwent intravenous pyelography (IVP) using a non-ionic, low osmolarity contrast medium. Of the 19 patients with KS, 10 had kidney abnormalities; four presented with unilateral renal agenesis and six had less severe forms of renal abnormality (renal malrotation in four and bilateral dilatation of the calyces and pelves in two). One of the patients with unilateral renal agenesis carried a deletion in KAL, the gene responsible for the X-linked type of KS. Three of the four patients with renal malrotation had a confirmed X-linked recessive form and one carried a point mutation in KAL. These results suggest that kidney abnormalities are more frequent and diverse in patients with KS than previously reported. They also indicate that defects in the KAL gene may contribute to abnormal renal development. However, a review of the literature revealed no close correlation between KAL mutations and kidney anomalies in the X-linked type of disease. Taken together, these data suggest that KAL mutations are not invariably associated with failure of renal development and that additional factors (epigenetic or local) may compensate for defects in the KAL protein.

    Renal cell carcinoma (RCC) is a very rare phenomenon in an ectopic kidney. We come across a 61-year-old gentleman with a history of 2 months of gross, painless haematuria and palpable pelvic mass on examination. CT scan showed 6.5cm X 5.1cm X 5.8cm mass in pelvic kidney with bilateral iliac vein invasion. With the help of intra-operative ultra-sound, tumour thrombus was extracted from both iliac veins with en mass removal of tumour. Patient was well intraoperatively as well as in postoperatively. We also presented an elegant imaging for the case. PMID:27134940

    We report pneumomediastinum, bilateral pneumothorax and acute respiratory distress syndrome in a victim of near drowning who was intoxicated and did not have thoracic or neck trauma. Chest radiograph revealed the above findings, later confirmed by computed tomography. He was in shock and also had gastrointestinal (GI) bleeding and renal dysfunction. With adequate resuscitative measures including fluids, blood transfusions, intercostal tube drainage and mechanical ventilation he made a complete recovery. Good prognostic indicators in near drowning patients include higher Glasgow Coma Scale, short submersion time and quick resuscitative measures even in the presence of serious cardiorespiratory or hemodynamic compromise.

    A 81-year-old male was referred to our emergency outpatient unit due to acute renal failure. The level of serum creatinine was 276 μmol/l. A CT scan showed bilateral hydronephroureter, large bladder stone (7 cm × 6 cm × 6 cm) and bladder wall thickness. He was diagnosed as post renal failure due to bilateral hydronephroureter. Large bladder stone is thought to be the cause of bilateral hydronephroureter and renal failure. To improve renal failure, we performed open cystolithotomy and urethral catheterization. Three days after the surgery, the level of serum creatinine decreased to 224 μmol/l. He was discharged from our hospital with uneventful course. Bladder calculus is thought to be a rare cause of renal failure. We summarize the characteristics of bladder calculus causing renal failure. We should keep that long-term pyuria and urinary symptom, and repeated urinary tract infection can cause huge bladder calculus and renal failure in mind.

  17. Renal transplantation using external continent urinary diversion.

    1994-02-01

    A 29-year-old man born with bladder exstrophy presented with end stage renal failure many years after ileal conduit diversion. Bilateral nephrectomy and continent external urinary diversion were performed, and 1.5 months later a cadaveric kidney was grafted into the right iliac fossa. The patient was well at 18 months with a serum creatinine level of 1.2 mg./dl. and he was completely dry with 4 or 5 daily catheterizations. Although followup is still short, renal transplantation with drainage into an external continent urinary diversion permits excellent quality of life and good renal function. Therefore, this alternative is worth consideration whenever other reconstructive alternatives are not possible in candidates for renal transplantation.

  19. Bimodal fitting or bilateral implantation?

    PubMed

    Ching, Teresa Y C; Massie, Robyn; Van Wanrooy, Emma; Rushbrooke, Emma; Psarros, Colleen

    2009-01-01

    This paper summarises findings from studies that evaluated the benefits of bimodal fitting (combining a hearing aid and a cochlear implant in opposite ears) or bilateral cochlear implantation, relative to unilateral implantation, for children (Ching et al., 2007). On average, the size of binaural speech intelligibility advantages due to redundancy and head shadow was similar for the two bilateral conditions. An added advantage of bimodal fitting was that the low-frequency cues provided by acoustic hearing complemented the high-frequency cues conveyed by electric hearing in perception of voice and music. Some children with bilateral cochlear implants were able to use spatial separation between speech and noise to improve speech perception in noise. This is possibly a combined effect of the directional microphones in their implant systems and their ability to use spatial cues. The evidence to date supports the provision of hearing in two ears as the standard of care.

  20. Acute renal failure in the newborn.

    Andreoli, Sharon Phillips

    2004-04-01

    Acute renal failure in the newborn is a common problem and is typically classified as prerenal, intrinsic renal disease including vascular insults, and obstructive uropathy. In the newborn, renal failure may have a prenatal onset in congenital diseases such as renal dysplasia with or without obstructive uropathy and in genetic diseases such as autosomal recessive polycystic kidney disease. Acute renal failure in the newborn is also commonly acquired in the postnatal period because of hypoxic ischemic injury and toxic insults. Nephrotoxic acute renal failure in newborns is usually associated with aminoglycoside antibiotics and nonsteroidal anti-inflammatory medications used to close a patent ductus arteriosis. Alterations in renal function occur in approximately 40% of premature newborns who have received indomethacin and such alterations are usually reversible. Renal artery thrombosis and renal vein thrombosis will result in renal failure if bilateral or if either occurs in a solitary kidney. Cortical necrosis is associated with hypoxic/ischemic insults due to perinatal anoxia, placenta abruption and twin-twin or twin-maternal transfusions with resultant activation of the coagulation cascade. As in older children, hospital acquired acute renal failure is newborns is frequently multifactorial in origin. Although the precise incidence and prevalence of acute renal failure in the newborn is unknown, several studies have shown that acute renal failure is common in the neonatal intensive care unit. Recent interesting studies have demonstrated that some newborns may have genetic risks factors for acute renal failure. Once intrinsic renal failure has become established, management of the metabolic complications of acute renal failure continues to involve appropriate management of fluid balance, electrolyte status, acid-base balance, nutrition and the initiation of renal replacement therapy when appropriate. Renal replacement therapy may be provided by peritoneal dialysis

    Since the advent of screening of calcium and imaging techniques (CT and MRI), hyperparathyroidism has been detected with increasing frequency. Although in the past, most patients present with severe bone and renal diseases, a large number of patients are asymptomatic. Number of parathyroid glands and their ectopic locations in individuals are the problem of its management. Parathyroid adenoma or hyperplasia may be a part of Multiple Endocrine neoplasia type II. This is the story of a boy of 18 years who had got admitted in the department of Otolaryngology, Mymensingh Medical College Hospital with the complaints of a neck swelling, abdominal discomfort, inability to walk, frequency of micturation for almost same duration of 1 year. After search, hypercalcaemia, bilateral renal stone, raised parathormone level and enlarged one parathyroid gland in lower pole of left thyroid lobe was identified. Clinically it was diagnosed as parathyroid adenoma which was proved histologically after surgical excision. Many controversies still exist regarding the treatment policy of parathyroid adenoma.

    Ureteral injury occurs in less than 1% of blunt abdominal trauma cases, partly because the ureters are relatively well protected in the retroperitoneum. Bilateral ureteral injury is extremely rare, with only 10 previously reported cases. Diagnosis may be delayed if ureteric injury is not suspected, and delay of 36 hours or longer has been observed in more than 50% of patients with ureteric injury following abdominal trauma, leading to increased morbidity. A 29-year-old man was involved in a highway motor vehicle collision and was ejected from the front passenger seat even though wearing a seatbelt. He was in a preshock state at the scene of the accident. An intravenous line and left thoracic drain were inserted, and he was transported to our hospital by helicopter. Whole-body, contrast-enhanced computed tomography (CT) scan showed left diaphragmatic disruption, splenic injury, and a grade I injury to the left kidney with a retroperitoneal haematoma. He underwent emergency laparotomy. The left diaphragmatic and splenic injuries were repaired. Although a retroperitoneal haematoma was observed, his renal injury was treated conservatively because the haematoma was not expanding. In the intensive care unit, the patient's haemodynamic state was stable, but there was no urinary output for 9 hours after surgery. Anuresis prompted a review of the abdominal x-ray which had been performed after the contrast-enhanced CT. Leakage of contrast material from the ureteropelvic junctions was detected, and review of the repeat CT scan revealed contrast retention in the perirenal retroperitoneum bilaterally. He underwent cystoscopy and bilateral retrograde pyelography, which showed bilateral complete ureteral disruption, preventing placement of ureteral stents. Diagnostic laparotomy revealed complete disruption of the ureteropelvic junctions bilaterally. Double-J ureteral stents were placed bilaterally and ureteropelvic anastomoses were performed. The patient's postoperative progress

    The choice of a single or bilateral lung transplant for interstitial lung disease (ILD) is controversial, as surgical risk, long-term survival and organ allocation are competing factors. In an effort to balance risk and benefit, our center adopted a staged bilateral lung transplant approach for higher surgical risk ILD patients where the patient has a single lung transplant followed by a second single transplant at a later date. We sought to understand the surgical risk, organ allocation and early outcomes of these staged bilateral recipients as a group and in comparison to matched single and bilateral recipients. Our analysis demonstrates that staged bilateral lung transplant recipients (n = 12) have a higher lung allocation score (LAS), lower pulmonary function tests and a lower glomerular filtration rate prior to the first transplant compared to the second (p < 0.01). There was a shorter length of hospital stay for the second transplant (p = 0.02). The staged bilateral compared to the single and bilateral case-matched controls had comparable short-term survival (p = 0.20) and pulmonary function tests at 1 year. There was a higher incidence of renal injury in the conventional bilateral group compared to the single and staged bilateral groups. The staged bilateral procedure is a viable option in select ILD patients.

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    We report a personal series of 28 patients with neurofibromatosis 2 (NF-2), emphasizing the differences from classical NF-1. The hallmark of NF-2 is bilateral acoustic neuromas with initial symptoms usually occurring in the second or third decade. The natural history may lead to bilateral deafness, but hearing loss may also be a complication of surgery. NF-2 is frequently accompanied by additional intracranial tumors (particularly multiple meningiomas). Half of our patients had a spinal space-occupying lesion. NF-2 is inherited as an autosomal dominant trait, and many patients appear to represent new mutations.

Renal biopsy and urine toxicology were consistent with ethylene glycol intoxication. Sequential neurophysiological examinations revealed sensory nerve axonal loss, proximal motor nerve conduction block and a proximodistal type of axonal degeneration. Seven months after ingestion, the patient improved and was able to walk unaided but with residual bilateral facial weakness and distal sensory loss.

    A 70-year-old man with a history of weight loss, changes in bowel habits, and hematochezia had rectal adenocarcinoma. He was palliated with diverting colostomy, followed by radiochemotherapy. Bilateral hydronephrosis was found incidentally on lower abdominal CT scan. He underwent 99mTc dimercaptosuccinic acid scan prior to percutaneous nephrostomy tube placement. Apart from the renal cortex, scintigraphy showed activity in the ascending colon continuous to the activity of the bladder. This indicated urine extravasation on account of a colovesical fistula, complicating postoperative radiation treatment. Here we highlight the contribution of renal cortical scintigraphy in the detection of colovesical fistulas.

    Simultaneous occurrence of multifocal urothelial carcinoma (UC) and ipsilateral renal cell carcinoma (RCC) is rare. We report a 67-year-old woman with multifocal, infiltrating urothelial carcinoma and unilateral renal cell carcinoma. She was referred to our department because of painless gross hematuria. Cystoscopy, computed tomography and retrograde pyelography studies revealed bladder, bilateral renal and ureter UC. She was treated with transurethral resection of the bladder tumor followed by bilateral nephroureterectomy. The pathological diagnosis was high-grade UC over the bladder and both renal pelves and ureters. A second tumor in the upper pole of the right kidney was reported as clear cell RCC. The patient was alive and still under careful surveillance at this writing.

    Guaifenesin is a common nonprescription medication that has been implicated in drug-induced nephrolithiasis. Dextromethorphan, a nonprescription antitussive found in some guaifenesin-containing preparations, is increasingly recognized as a substance of abuse by many youth and young adults. Renally excreted medications known to have poor solubility in urine have the potential to precipitate when ingested in large quantity, leading to acute obstruction of the ureters and renal failure. We describe the case of a 22-year-old male who developed severe bilateral flank pain, hematuria, and oliguria after an isolated recreational ingestion of guaifenesin and dextromethorphan. The patient was found to have bilateral ureteral obstruction and acute renal failure, suspected to be secondary to precipitation of medication metabolites in the urine. This case highlights the potential for acute renal failure secondary to guaifenesin and dextromethorphan abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

    Upper urinary tract tumours are exceptional in the context of renal polycystic disease. The authors report the case of Mrs B. F., 56 years old, who presented with left loin pain associated with haematuria. Clinical examination was normal and ultrasound examination revealed bilateral renal polycystic disease with a mass in the left renal sinus. CT urography showed a tumour arising from the renal pelvis suggestive of an upper urinary tract tumour. The laboratory assessment revealed normal renal function and normal urine cytology. Treatment consisted of radical nephroureterectomy with resection of a bladder cuff. Histological examination revealed a urothelial tumour of the renal pelvis with negative surgical margins. In the light of this case, the authors discuss the diagnostic difficulties and specificities, the treatment and the outcome of this unusual clinical association.

    Wilms' tumour originates predominantly in the renal tissue; in rare cases it can also arise from extra-renal sites accounting for 0.5-1% of cases of Wilms' tumours seen. A diagnosis of extra-renal Wilms' cannot be easily established with clinical and radiological features except when the histological facts are provided. Wilms' tumours arising from extra-renal sites may not be different in clinical features, protocol of treatment and outcome from a typical intra renal Wilms' tumour. A 2-year-old boy presented with an asymptomatic abdominal swelling for 3 months. Abdominal ultrasound and CT scans revealed an extra-renal mass. Intravenous urogram (IVU) showed prompt excretion bilaterally. Post excision histology of the tumour confirmed a Wilms' tumour.

    Perirenal fluid accumulation has been described as an ultrasonographic feature of urine leakage, hemorrhage, abscessation, or neoplasia. The purpose of this retrospective study was to report perirenal effusion as an additional ultrasonographic finding in canine and feline patients with acute renal failure. The causes of acute renal failure in 18 patients included nephrotoxicity (4), leptospirosis (3), ureteral obstruction (2), renal lymphoma (2), ureteronephrolithiasis (2), prostatic urethral obstruction (1) and interstitial nephritis and ureteritis (1). An underlying cause was not identified in three patients. The sonographic finding of perirenal fluid was bilateral in 15 patients. Unilateral perirenal fluid was identified ipsilateral to the site of ureteric obstruction in two patients. Large effusions extended into the caudal retroperitoneal space. Additional sonographic findings suggestive of renal parenchymal disease included mild (5), moderate (5) or severe (2) pyelectasia, increased renal echogenicity (11), increased (9) or decreased renal size (2) and ureteral and/or renal calculi (3). There did not appear to be an association between the volume of perirenal fluid and the severity of renal dysfunction. All patients with large effusions underwent euthanasia. Perirenal fluid developing in acute renal failure is thought to be an ultrafiltrate associated with tubular back-leak into the renal interstitium that overwhelms lymphatic drainage within the perirenal and retroperitoneal connective tissues although obstruction to urine flow may also play a role. Localized perirenal retroperitoneal free fluid may be a useful ultrasonographic feature to assist with the characterization of, and determination of prognosis in, patients with suspected renal disease.

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis.

    Bilateral arm training has emerged as an approach that leads to positive outcomes in addressing upper extremity paresis after stroke. However, studies have not demonstrated improvements in all patients using current outcome measures. Furthermore, the rationale for using this type of training has been incompletely explained. The purpose of this article was to first review the theoretical justifications for the use of bilateral arm training by examining motor control and neural mechanisms underlying arm function and neural recovery, and second, to discuss examples of clinical studies using a variety of bilateral training strategies to identify who may benefit most from this approach. We argue that bilateral arm training is a necessary adjunct to unilateral training because bilateral re-training is important and best served through bilateral not unilateral training, and also, that bilateral training may help unilateral skill recovery through alternative putative mechanisms. Our review of the empirical evidence suggests that individuals at all levels of severity can benefit in some manner from bilateral training, but that not all approaches are effective for all severity levels. In addition to requesting more randomized controlled trials and studies of neurophysiological mechanisms we conclude the following: 1) Bilateral training can improve unilateral paretic limb functions of the upper extremity after stroke, however, specific training approaches need to be matched to baseline characteristics of the patients; 2) Given the importance of bilateral activities in daily life, there is a need to recognize, train and assess the important contribution of supportive role functions of the paretic arm used on its own and as part of complementary bilateral functional skills; 3) An assessment of bilateral and unilateral functioning which includes bilateral task analysis, as well as, evaluations of interlimb coordination should be included in all studies that include bilateral

In addition to requesting more randomized controlled trials and studies of neurophysiological mechanisms we conclude the following: 1) Bilateral training can improve unilateral paretic limb functions of the upper extremity after stroke, however, specific training approaches need to be matched to baseline characteristics of the patients; 2) Given the importance of bilateral activities in daily life, there is a need to recognize, train and assess the important contribution of supportive role functions of the paretic arm used on its own and as part of complementary bilateral functional skills; 3) An assessment of bilateral and unilateral functioning which includes bilateral task analysis, as well as, evaluations of interlimb coordination should be included in all studies that include bilateral

    A 31-year-old woman had bilateral retinoblastoma diagnosed in early childhood. The right eye was enucleated at the age of 1 year, and the left eye was treated with radiation therapy (a total dose of 16,000 rad). Twenty-three years later, in 1975, a subcutaneous mass was noted in the left periorbital region. A biopsy specimen of the mass was taken and a diagnosis of pleomorphic postradiation sarcoma was made. Electron microscopic studies of the periorbital mass confirmed the diagnosis of leiomyosarcoma. After additional radiation therapy, the residual mass was surgically excised. Five years later, a right renal mass, which histologically proved to be a renal cell carcinoma, was discovered. She was treated with nephrectomy, radiation, and chemotherapy. A recent follow-up examination disclosed that the patient is alive and apparently without any evidence of metastatic disease, 30 years after the diagnosis of bilateral retinoblastoma was made. The literature is reviewed regarding postradiation sarcomas and the occurrence of second malignant neoplasms in patients with retinoblastoma.

    BACKGROUND: Radionuclide techniques, as direct radionuclide cystography and 99mTc-DMSA scintigraphy, have been used in evaluation of vesicoureteral reflux (VUR) and reflux nephropathy (RN) in children. Dynamic 99mTc-DTPA scintigraphy is reserved for evaluation of differential renal function and obstruction in children, where hydronephrosis is detected by ultrasonography (US) pre- or postnatally. CASE REPORT: Six year old boy was prenatally diagnosed with bilateral hydronephrosis. Postnatal, severe bilateral VUR was detected by voiding urethrocytography. US and 99mTc-DTPA scintigraphy performed in the first month of life showed small left kidney that participated with 2% in the global renal function. Bilateral cutaneous ureterostomy has been performed in order to obtain good renal drainage and promote optimal renal growth. Twelve months later, classic antireflux procedure was done. Control 99mTc-DTPA scintigraphy, 5 ys after antireflux surgery, revealed persisting radioactivity during the diuretic phase, in the left kidney that indicated antireflux procedure failure with VUR reappearance. CONCLUSION: 99mTc-DTPA scintigraphy is the first method of choice for long-term monitoring of individual kidney function in children with VUR and other congenital urinary tract anomalies. Additionally, it can be used as indirect radionuclide cystography when rising of radioactivity in the kidney region, during the diuretic phase can indicate presence of VUR. PMID:27275347

    Renal angiomyolipomata associated with tuberous sclerosis complex are often bilateral, multiple and progressive. They cause significant morbidity and mortality in older children and adults. Surveillance and pre-emptive treatment reduce this risk. Recent research suggests treatment with mammalian target of rapamycin inhibitors is better at preventing bleeding, recurrence, and preserving renal function than percutaneous embolization.

    Acrokeratosis verruciformis (AKV) of Hopf is an autosomal dominant genodermatosis with unknown etiology. It is characterized by multiple flat-topped keratotic papules resembling planar warts located mainly on the dorsum of hands and feet. Superficial ablation is the treatment of choice. A 41-year-old female presented with multiple hyperpigmented, hyperkeratotic papules and plaques over flexor aspect of both forearms, extensors of both legs and dorsum of the feet. Histopathology showed changes of AKV. Patient was treated with a combination of topical corticosteroids and cryotherapy with no visible improvement. PMID:25821733

    1985-12-01

    Urine from one female and 2 male Asian small-clawed otters (Aonyx cinerea) with bilateral renal calculi, one female with unilateral calculi, and one nonaffected male were evaluated for abnormal urinary crystalloid excretion. One otter with bilateral renal calculi had cystic calculi composed of calcium oxalate monohydrate and dihydrate. The 2 affected males were littermates, as were the 2 affected females, but the 2 litters were from different parents. At the time of the study, the otters did not have clinical signs of disease. Hematologic and serum biochemical, electrolyte, and enzyme values were normal. The urinary excretion of calcium, oxalate, uric acid, phosphate, citrate, and amino acids in otters with renal calculi was similar to that of the nonaffected otter. The 4 otters with renal calculi had glucosuria but the nonaffected otter did not have glucosuria. The glucosuria, in the absence of hyperglycemia, suggested a renal tubular transport defect for glucose. Other renal abnormalities were not found.

    Primary renal lymphoma is a controversial entity. Only 29 cases have been reported since 1980. Diagnostic criteria are not well established. We report here 3 new cases and review the literature. Primary renal lymphoma was considered on the basis of uni- or bilateral nonobstructive nephromegaly with or without renal failure. In all cases, the diagnosis was made after renal biopsy. Extrarenal abdominal involvement was excluded by imaging techniques. The role of staging laparotomy remains controversial. Chemotherapy is the treatment of choice, but the prognosis is poor. We propose a clinical definition of primary renal lymphoma in order to achieve a better management of the disease.

    Renal Osteodystrophy (ROD) is a common complication of chronic renal disease (CRD) and is the part of a broad spectrum of disorders of mineral metabolism that occurs in the clinical setting. It occurs early in the course of chronic renal failure and progresses as the kidney function deteriorates. It is an osseous alteration believed to arise from increased parathyroid function associated with inappropriate calcium, phosphorus and vitamin D metabolism. Involvement of the jaws is common and radiographic alterations are often one of the earliest signs of chronic renal failure. Herein, reporting a case of Chronic Renal Failure (Bilateral Grade I Neuropathy) with ROD presenting oral manifestations in an 11-year -old male child.

    A 15-month-old girl was referred for evaluation of congenital absence of both eyelids. Clinical evaluation revealed bilateral total cryptophthalmos and enlarged globes in addition to genitourinary anomalies, umbilical hernia, renal agenesis, and facial anomalies. The clinical findings were consistent with Fraser syndrome. Magnetic resonance imaging of the orbits revealed dysplastic globes that were characterized by cystic expansions that extended laterally anterior to the lateral orbital rim. Bilateral orbito-palpebral cysts that communicate with a dysplastic globe and extend beyond the orbital cavity may be a rare presenting feature of Fraser syndrome.

  6. Hypertension and hydronephrosis: rapid resolution of high blood pressure following relief of bilateral ureteric obstruction.

    2013-03-01

    Hypertension secondary to hydronephrosis is not commonly reported in the medical literature. Tubuloglomerular feedback and the renin-angiotensin-aldosterone axis are thought to mediate this process. We describe a patient presenting with acute kidney injury and bilateral hydronephrosis secondary to pelvic malignancy in which peripheral venous renin and aldosterone were elevated. Her blood pressure improved rapidly following insertion of bilateral nephrostomies. The speed of resolution of hypertension following relief of obstruction suggests that humorally mediated vasoconstriction can play an important role in the mechanism by which hydronephrosis causes hypertension. We also discuss other causes of renal parenchymal compression that may lead to the development of hypertension.

    Although tonsilloliths are reported to be fairly common, florid cases casting distinct radiopaque shadows on panoramic radiographs are not often reported. This report illustrates such a case as an incidental finding in an asymptomatic 38-year-old female dental patient. Panoramic radiography revealed distinct radiopaque shadows over the ascending rami of the mandible bilaterally. These radiopacities were localized to the palatine tonsils by computerized tomographic inspection. Tonsillectomy was performed and tonsillolithiasis was confirmed by histopathologic examination.

    A patient who had undergone his third orthotopic liver transplantation nearly 9 years prior to presentation developed worsening hepatic and renal function, as well as severe bilateral lower extremity edema. Magnetic resonance imaging demonstrated vena caval thrombosis from the suprahepatic venous anastomosis to the infrarenal inferior vena cava, obstructing the renal veins. This was treated by percutaneous placement of metallic stents from the renal veins to the right atrium. At 16 months clinical follow-up, the patient continues to do well.

    Two 12-year-old cats were diagnosed with chronic kidney disease (CKD) based on physical examination, clinicopathologic data and, in one case, abdominal ultrasound findings. Approximately 1 year after the initial diagnosis of CKD both cats developed renal transitional cell carcinoma (TCC)--bilateral in one cat. Based on post-mortem examination, one cat had no evidence of metastasis and the other had metastasis to the large intestine, heart and lungs. This is the first report of de novo bilateral renal TCC in a cat, as well as the first report of renal TCC developing in cats with previous history of confirmed CKD.

  10. Screening for a renovascular etiology in hypertensive patients undergoing myocardial scintigraphy: differential renal thallium-201 uptake.

    In hypertensive patients with target organ damage the search for possible etiologic factors may be particularly relevant. To evaluate renal symmetry, differential renal uptake of thallium-201 was quantified on renal images at 30 mins to 3 h after tracer injection in 112 hypertensive patients undergoing myocardial perfusion scintigraphy for chest pain. In some patients, renal angiographic status was known at the time of thallium-201 scintigraphy (n = 10), or disease was highly suspected (failed angioplasty, n = 6); the remainder (n = 96) were 'screened' for renovascular disease by renal thallium-201 imaging; 32 normotensive patients with no history of renal disease served as controls. Validation of thallium-201 renal imaging was obtained in a total of 17 hypertensive patients who had correlating contrast angiography, confirming eight cases of unilateral or asymmetric bilateral renovascular disease. Renography with technetium-99m DTPA was performed in 28 patients; differential renal function according to this modality correlated well with differential renal uptake of thallium-201 (r = 0.98). Of the screened hypertensives, eight had marked asymmetry of differential renal uptake and eight had possibly significant asymmetry. Renal thallium-201 imaging provided the first evidence of asymmetric renal perfusion in four cases subsequently confirmed by abdominal angiography. In addition, four post angioplasty cases had persistent or progressive asymmetry of renal perfusion disclosed by this technique. Thus, ancillary renal imaging with thallium-201 can be used to identify hypertensive patients who should be considered for renal angiographic evaluation.

  11. Ultrasound diagnosis of fetal renal abnormalities.

    Development of the urogenital system in humans is a complex process; consequently, renal anomalies are among the most common congenital anomalies. The fetal urinary tract can be visualised ultrasonically from 11 weeks onwards, allowing recognition of megacystis at 11-14 weeks, which warrants comprehensive risk assessment of possible underlying chromosomal aneuploidy or obstructive uropathy. A mid-trimester anomaly scan enables detection of most renal anomalies with higher sensitivity. Bilateral renal agenesis can be confirmed ultrasonically, with empty renal fossae and absent bladder filling, along with severe oligohydramnios or anhydramnios. Dysplastic kidneys are recognised as they appear large, hyperechoic, and with or without cystic spaces, which occurs within the renal cortex. Presence of dilated ureters without obvious dilatation of the collecting system needs careful examination of the upper urinary tract to exclude duplex kidney system. Sonographically, it is also possible to differentiate between infantile type and adult type of polycystic kidney diseases, which are usually single gene disorders. Upper urinary tract dilatation is one of the most common abnormalities diagnosed prenatally. It is usually caused by transient urine flow impairment at the level of the pelvi-ureteric junction and vesico-ureteric junction, which improves with time in most cases. Fetal lower urinary tract obstruction is mainly caused by posterior urethral valves and urethral atresia. Thick bladder walls and a dilated posterior urethra (keyhole sign) are suggestive of posterior urethral valves. Prenatal ultrasounds cannot be used confidently to assess renal function. Liquor volume and echogenicity of renal parenchyma, however, can be used as a guide to indirectly assess the underlying renal reserve. Renal tract anomalies may be isolated but can also be associated with other congenital anomalies. Therefore, a thorough examination of the other systems is mandatory to exclude possible

    To determine the incidence of bilateral distal biceps tendon ruptures. A retrospective review of 321 patients who underwent operative repair of a distal biceps tendon rupture between 1988 and 2010 identified 26 patients with bilateral ruptures. We recorded patient age, mechanism of injury, time between symptom onset before the first surgery and subsequent contralateral symptoms, and time between surgeries. Twenty-two bilateral ruptures were confirmed intra-operatively, 3 by MRI, and 1 was lost to follow up. A total of 23 bilateral ruptures (92%) occurred in men. The average age at the initial rupture was 44 years (range, 29-74 y). The average age at subsequent rupture was 48 years (range, 36-79 y). Excluding the 2 women (age 72 and 79 y), the average age at the initial rupture was 42 years and the average age at subsequent rupture was 46 years. The average interval between ruptures was 4.1 years (range, 0.8-13.9 y). The initial rupture occurred in the dominant extremity in 12 cases (50%) and in the nondominant extremity in 10 cases (42%); in 3 patients (8%) the dominance was not documented or ambidextrous. Thirty-three percent were heavy laborers, 3 patients had a smoking history, and 1 patient reported a history of steroid use. Twenty-two patients (88%) had the second side repaired, where we noted that 12 (55%) of the second tendon ruptures were partial tears. The 8% cumulative incidence of bilateral biceps tendon ruptures in a consecutive series of biceps tendon repairs may be higher because not all patients were contacted, which introduced a sampling bias. This 8% rate is markedly higher than the reported rate of 1.2 per 100,000 for an isolated distal biceps tendon rupture. This implies that patients with a distal biceps tendon rupture are at risk for a rupture on the contralateral side. Prognostic III. Copyright © 2012 American Society for Surgery of the Hand.

    The pathogenesis of renal calculi is reviewed in general terms followed by the results of investigation of 439 patients with renal calculi studied by the author at Toronto General Hospital over a 13-year period. Abnormalities of probable pathogenetic significance were encountered in 76% of patients. Idiopathic hypercalciuria was encountered in 42% of patients, primary hyperparathyroidism in 11%, urinary infection in 8% and miscellaneous disorders in 8%. The incidence of uric acid stones and cystinuria was 5% and 2% respectively. In the remaining 24% of patients in whom no definite abnormalities were encountered the mean urinary magnesium excretion was less than normal. Of 180 patients with idiopathic hypercalciuria, only 24 were females. In the diagnosis of hyperparathyroidism, the importance of detecting minimal degrees of hypercalcemia is stressed; attention is also drawn to the new observation that the upper limit of normal for serum calcium is slightly lower in females than in males. The efficacy of various measures advocated for the prevention of renal calculi is also reviewed. In the author's experience the administration of thiazides has been particularly effective in the prevention of calcium stones. Thiazides cause a sustained reduction in urinary calcium excretion and increase in urinary magnesium excretion. These agents also appear to affect the skeleton by diminishing bone resorption and slowing down bone turnover. PMID:5438766

    Our purpose was to evaluate the prevalence of renal artery stenosis in patients with critical limb ischemia and to study any clinical or laboratory indicator that could predict this association. One hundred consecutive patients with critical limb ischemia evaluated by angiogram were included in the study from January to July 2003. Cardiovascular risk factors and renal function were analyzed. One hundred angiographic studies have been analyzed. Thirty nine (39%) of our patients had some type of pathology of the renal artery but the rest, 61 (61%), had normal and healthy renal arteries. In 5 patients, a bilateral renal pathology was found. Severe disease (> 60% stenosis, bilateral or renal occlusion) was present in 15 cases including 6 occlusions. Once we compared the patients with healthy renal arteries with the patients with different degrees of stenosis, we did not appreciate significant differences in hypertension, diabetes, coronary disease or smoking habit, nor with laboratory data such as creatinine, urea, c-reactive protein, total cholesterol or atherogenic index. No differences were found either comparing patients with normal renal artery with patients with bilateral pathology or with unilateral occlusion. There is a high prevalence of renal artery pathology in patients with critical limb ischemia although we have not found any clinical or laboratory factors useful to identify them.

    The syndrome of hereditary thrombocytopenia, deafness, and renal disease was manifest in at least eight members in three generations of a family. They had a lifelong history of bleeding, usually as epistaxis, bilateral sensorineural deafness starting in late childhood or the teenage years, and persistent proteinuria with varying degrees of renal dysfunction. Two members died at a young age, one from central nervous system hemorrhage, the other from chronic renal failure. Splenectomy and steroid therapy have been of transient benefit. There was dominant inheritance of the syndrome. Hematologic studies showed thrombocytopenia, large platelets, and megakaryocytic hyperplasia of the bone marrow. In contrast to a previous report, our studies showed that affected members had normal in-vitro platelet function and normal ultrastructural platelet morphology. At autopsy, histologic changes in the kidney of one affected family member were indistinguishable from those reported in classic hereditary nephritis with nerve deafness (Alport's syndrome).

    PubMed Central

    2013-01-01

    Abstract Teratomas are neoplasms that arise from pluripotent cells and can differentiate along one or more embryonic germ lines. Renal teratoma is an exceedingly rare condition. Teratomas commonly arise in the gonads, sacrococcygeal region, pineal gland, and retroperitoneum. They present mainly as an abdominal mass with few other symptoms. Majority of the tumors are benign, situated on the left side and para renal, occasional lesions are bilateral. If diagnosed early, they are amenable to curative excision. Renal teratomas are rare and most have been dismissed as cases of teratoid nephroblastomas or retroperitoneal teratomas secondarily invading the kidney. The differentiation between these two neoplasms in the kidney is often problematic. We present a case of intrarenal immature teratoma in a six-month-old baby girl.

    Germline mutations of c-met oncogene at 7q31 have been detected in patients with hereditary papillary renal cell carcinoma. In addition, c-met mutations were shown to play a role in 13% of patients with papillary renal cell carcinoma and no family history of renal tumors. The histopathology of papillary renal cell carcinoma with c-met mutations has not been previously described. We analyzed the histopathology of 103 bilateral archival papillary renal cell carcinomas and 4 metastases in 29 patients from 6 hereditary papillary renal cell carcinoma families with germline c-met mutations and 6 papillary renal cell carcinomas with c-met mutations from 5 patients with no family history of renal tumors. Twenty-five sporadic renal tumors with prominent papillary architecture and without somatic c-met mutations were evaluated for comparison. All papillary renal cell carcinomas with c-met mutations were 75 to 100% papillary/tubulopapillary in architecture and showed chromophil basophilic, papillary renal cell carcinoma type 1 histology. Fuhrman nuclear grade 1–2 was seen in tumors from 23 patients, and nuclear grade 3 was observed focally in 8 patients. Seventeen patients had multiple papillary adenomas and microscopic papillary lesions in the surrounding renal parenchyma. Clear cells with intracytoplasmic lipid and glycogen were focally present in tumors of 94% papillary renal cell carcinoma patients. Clear cells of papillary renal cell carcinoma had small basophilic nuclei, and clear cell areas lacked a fine vascular network characteristic of conventional (clear) cell renal cell carcinoma. We conclude that papillary renal cell carcinoma patients with c-met mutations develop multiple, bilateral, papillary macroscopic and microscopic renal lesions. Renal tumors with c-met genotype show a distinctive papillary renal cell carcinoma type 1 phenotype and are genetically and histologically different from renal tumors seen in other hereditary renal syndromes and most sporadic

    Previous series showed controversial differential renal function outcomes after pyeloplasty in children. However, they were limited by study power, methodology and lack of comparable end points. We determined the status of differential renal function after pyeloplasty in children in what is to our knowledge the largest series to date. After excluding patients with renal anomalies, solitary kidney or bilateral pyeloplasty from analysis, we retrospectively identified 196 younger than 18 years who were treated with pyeloplasty between May 2002 and January 2010 and had preoperative and postoperative renal scintigraphy available. Primary outcome measures were greater than 5% improvement in baseline differential renal function and baseline weighted differential renal function at last followup. Clinical variables predicting outcome measures were determined using univariable and multivariable analyses. During a median followup of 12 months, mean ± SD differential renal function improved from 35.8% ± 10% to 38.7% ± 11% (p <0.001). In the poor and intermediate groups baseline differential renal function improved, while in the good group function was static postoperatively (p <0.001). The linear regression model showed that only baseline differential renal function explained the variance in baseline weighted differential renal function (β = -0.393, p <0.001). In the Cox proportional hazards model baseline differential renal function (less than 35% HR 3.196, p <0.001 and 35% to 40% HR 2.733, p = 0.002) and cortical thickness (HR 2.114, p = 0.029) were the only predictors of a greater than 5% improvement in postoperative differential renal function. Renal function improves after pyeloplasty in children. Baseline differential renal function and cortical thickness predict improvement after surgery.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Nephrogenic diabetes insipidus (NDI) is a condition resulting from the kidney's impaired response to circulating antidiuretic hormone (ADH), leading to polydipsia and polyuria. Urinary tract dilatation caused by NDI is a rare situation. Here, we report a case of congenital NDI presented with bilateral hydronephrosis.A 15-year-old boy complaining a history of intermittent fever was admitted to Peking Union Medical College Hospital. He voided 10 to 15 L of urine daily. Radiographic examination revealed severe dilatation of bilateral renal pelvis, ureter, and bladder. Urinalysis shows hyposthenuria.He was diagnosed NDI since born. Transient insertion of a urethral catheter helped to relieve fever. Medical therapy of hydrochlorothiazide and amiloride was prescribed and effective.Dilatation of urinary tract caused by diabetes insipidus is rare, but may be present in severe condition. Therefore, it is crucial for clinicians to perform early treatment to avoid impairment of renal function.

A 15-year-old boy complaining a history of intermittent fever was admitted to Peking Union Medical College Hospital. He voided 10 to 15 L of urine daily. Radiographic examination revealed severe dilatation of bilateral renal pelvis, ureter, and bladder. Urinalysis shows hyposthenuria. He was diagnosed NDI since born. Transient insertion of a urethral catheter helped to relieve fever. Medical therapy of hydrochlorothiazide and amiloride was prescribed and effective. Dilatation of urinary tract caused by diabetes insipidus is rare, but may be present in severe condition. Therefore, it is crucial for clinicians to perform early treatment to avoid impairment of renal function. PMID:27258490

    Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM) too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it's management both at the time of cleft lip repair and also secondarily

    Preoperative knowledge of the renal vascular anatomy is important for selection of the appropriate feline renal donor. Intravenous urograms (IVUs) have been performed routinely to screen potential donors at the Veterinary Hospital of the University of Pennsylvania (VHUP), but the vascular phase views lack sufficient detail of the renal vascular anatomy. Computed tomography angiography (CTA), which requires a helical computed tomography (CT) scanner, has been found to provide superior renal vascular anatomic information of prospective human renal donors. The specific aims of this study were as follows: 1) develop the CTA technique for the feline patient; and 2) obtain preliminary information on feline renal vessel anatomy in potential renal donors. Ten healthy, potential feline renal donors were anesthetized and imaged using a third-generation helical CT scanner. The time delay between i.v. contrast medium injection and image acquisition, and other parameters of slice collimation, slice interval, pitch, exposure settings, and reconstruction algorithms were varied to maximize contrast medium opacification of the renal vascular anatomy. Optimal CTA acquisition parameters were determined to be: 1) 10-sec delay post-i.v. bolus of iodinated contrast medium; 2) two serially acquired (corresponding to arterial and venous phases) helical scans through the renal vasculature; 3) pitch of 2 (4 mm/sec patient translation, 2 mm slice collimation); and 4) 120-kVp, 160-mA, and 1-sec exposure settings. Retrospective reconstructed CTA transverse images obtained at a 2-mm slice width and a 1-mm slice interval in combination with two-dimensional reformatted images and three-dimensional reconstructed images were qualitatively evaluated for vascular anatomy; vascular anatomy was confirmed at surgery. Four cats had single renal arteries and veins bilaterally; four cats had double renal veins. One cat had a small accessory artery supplying the caudal pole of the left kidney. One cat had a

    Talon cusp is an uncommon condition often present in the maxillary incisors and mandibular premolars. Morphologically, this anomaly has a well-delineated cusp that extends at least half the distance from the cementoenamel junction or cingulum area to the incisal edge. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case and should be as conservative as possible. Presented is a case of bilateral bifid talon cusp in maxillary central incisors that was successfully managed with conservative therapy.

    Isolated submandibular swellings pose a diagnostic challenge to the practising otolaryngologist. We report an unusual case of mumps isolated to bilateral submandibular glands. We discuss the case and the literature surrounding this condition and remind clinicians that mumps should be considered as a diagnosis in the presence of submandibular gland swelling in the absence of typical parotid swelling associated with mumps. Early consideration of this differential diagnosis, serological testing and a multidisciplinary approach may help to clinch the diagnosis earlier and prevent spread of the virus. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Inguinal hernias are rare in females. The authors report a case of bilateral inguinal hernias in a 10-year-old female. On exploration, the patient was found to be having a sliding hernia containing incarcerated ovary as contents on both sides. Peroperatively the contents were reduced, the sac was transfixed at its base and the redundant sac was excised. The repair of this form of hernias is more difficult because of adhesions between the contents and the wall of the sac and risk of damage during dissection. A description of this clinical presentation in the pre operative assessment and operative management are discussed in this report. PMID:25918632

    The authors report a case of a 49-year-old woman presenting a Cushing's syndrome (January 1997). The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

Her urinary pregnancy test was positive. Initial transvaginal ultrasound demonstrated an irregular complex structure with a fluid filled centre in the right adnexum. Despite the diagnosis of a possible underlying unruptured right tubal ectopic pregnancy, she declined surgical intervention and was managed expectantly as an inpatient. When she complained of increasing abdominal pain with haemodynamic instability, an emergency laparotomy was performed and a diagnosis of bilateral tubal ectopic pregnancy was made.

    Telemanipulator system includes master robot manipulated by human operator, and slave robot performing tasks at remote location. Two robots electronically coupled so slave robot moves in response to commands from master robot. Teleoperation greatly enhanced if forces acting on slave robot fed back to operator, giving operator feeling he or she manipulates remote environment directly. Main advantage of bilateral impedance control: enables arbitrary specification of desired performance characteristics for telemanipulator system. Relationship between force and position modulated at both ends of system to suit requirements of task.

    Medullary cystic kidney disease (MCKD) is a hereditary disease associated with bilateral medullary polycysts and interstitial fibrosis. MCKD is typically associated with slowly progressive renal dysfunction. We herein report two rare elderly cases with enlarged kidneys and rapidly progressive renal dysfunction without myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA), PR3-ANCA, or anti-glomerular basement membrane (GBM) antibodies. Renal biopsies revealed extensive tubular dilatation and atrophy with interstitial fibrosis consistent with MCKD. Both patients began hemodialysis therapy a few months later. Our cases suggest a MCKD subgroup among elderly patients with an undefined genetic background, rapidly progressive renal dysfunction, and enlarged kidneys. PMID:27746439

    The term “ultima ratio” has multiple, though related, meanings. The motto “ultima ratio regum,” cast on the cannons of the French army of King Louis XIV, meant that war is the last argument of kings, that is, the one to be used after all diplomatic arguments have failed. Along similar lines, we propose that, given the current evidence, renal denervation should be used as a last resort, after state-of-the-art drug treatment optimized at expert centers failed to control blood pressure.

    Anatomic and physiologic adaptations within the renal system during pregnancy are significant. Alterations are seen in renal blood flow and glomerular filtration, resulting in changes in normal renal laboratory values. When these normal renal adaptations are coupled with pregnancy-induced complications or preexisting renal dysfunction, the woman may demonstrate a reduction of renal function leading to an increased risk of perinatal morbidity and mortality. This article will review normal pregnancy adaptations of the renal system and discuss common pregnancy-related renal complications.

    A 32-year old hypertensive woman with bilateral renal artery stenosis of more than 50% on both sides was studied. Renal vein renin levels were low (0.3 ng/ml/h on the right side and 0.42 on the left) before surgical correction of the left renal artery. Thereafter, blood pressure was only temporarily reduced. Four months later a repeat angiography demonstrated a widely patent left renal artery and the stenosis on the right side was unchanged. Renal vein renin was 5.12 on the left and 11.2 on the right. Subsequent operation on the right side lead to normalization of blood pressure. Thus, our patient seems to demonstrate in sequence the characteristics of the tow types of experimental renovacular hypertension known as "one kidney hypertension" and "two kidney hypertension". Our findings usggest that the pathomechanisms of these experimental models are operative in man too.

    PurposeRenal denervation (RDN) emerged as an innovative interventional antihypertensive therapy. With the exception of pretreatment blood pressure (BP) level, no other clear predictor for treatment efficacy is yet known. We analyzed whether the presence of multiple renal arteries has an impact on BP reduction after RDN.MethodsFifty-three patients with treatment-resistant hypertension (office BP {>=} 140/90 mmHg and 24-h ambulatory BP monitoring ({>=}130/80 mmHg) underwent bilateral catheter-based RDN. Patients were stratified into one-vessel (OV) (both sides) and at least multivessel (MV) supply at one side. Both groups were treated on one vessel at each side; in case of multiple arteries, only the dominant artery was treated on each side.ResultsBaseline clinical characteristics (including BP, age, and estimated glomerular filtration rate) did not differ between patients with OV (n = 32) and MV (n = 21). Office BP was significantly reduced in both groups at 3 months (systolic: OV -15 {+-} 23 vs. MV -16 {+-} 20 mmHg; diastolic: OV -10 {+-} 12 vs. MV -8 {+-} 11 mmHg, both p = NS) as well as 6 months (systolic: OV -18 {+-} 18 vs. MV -17 {+-} 22 mmHg; diastolic: OV -10 {+-} 10 vs. -10 {+-} 12 mmHg, both p = NS) after RDN. There was no difference in responder rate (rate of patients with office systolic BP reduction of at least 10 mmHg after 6 months) between the groups.ConclusionIn patients with multiple renal arteries, RDN of one renal artery-namely, the dominant one-is sufficient to induce BP reduction in treatment-resistant hypertension.

    The World Health Organization recommends direct observation of treatment (DOT) to support patients with tuberculosis (TB) and to ensure treatment completion. As per national programme guidelines in India, a DOT provider can be anyone who is acceptable and accessible to the patient and accountable to the health system, except a family member. This poses challenges among children with TB who may be more comfortable receiving medicines from their parents or family members than from unfamiliar DOT providers. We conducted a non-inferiority trial to assess the effect of family DOT on treatment success rates among children with newly diagnosed TB registered for treatment during June-September 2012. We randomly assigned all districts (n = 30) in Gujarat to the intervention (n = 15) or usual-practice group (n = 15). Adult family members in the intervention districts were given the choice to become their child's DOT provider. DOT was provided by a non-family member in the usual-practice districts. Using routinely collected clinic-based TB treatment cards, we compared treatment success rates (cured and treatment completed) between the two groups and the non-inferiority limit was kept at 5%. Of 624 children with newly diagnosed TB, 359 (58%) were from intervention districts and 265 (42%) were from usual-practice districts. The two groups were similar with respect to baseline characteristics including age, sex, type of TB, and initial body weight. The treatment success rates were 344 (95.8%) and 247 (93.2%) (p = 0.11) among the intervention and usual-practice groups respectively. DOT provided by a family member is not inferior to DOT provided by a non-family member among new TB cases in children and can attain international targets for treatment success.

    Bystander-initiated cardiopulmonary resuscitation (CPR) has been reported to increase the possibility of survival in patients with out-of-hospital cardiopulmonary arrest (OHCA). We evaluated the effects of CPR instructions by emergency medical dispatchers on the frequency of bystander CPR and outcomes, and whether these effects differed between family and non-family bystanders. We conducted a retrospective cohort study, using Utstein-style records of OHCA taken in a rural area of Japan between January 2004 and December 2009. Of the 559 patients with non-traumatic OHCA witnessed by laypeople, 231 (41.3%) were given bystander CPR. More OHCA patients received resuscitation when the OHCA was witnessed by non-family bystanders than when it was witnessed by family members (61.4% vs. 34.2%). The patients with non-family-witnessed OHCA were more likely to be given conventional CPR (chest compression plus rescue breathing) or defibrillation with an AED than were those with family-witnessed OHCA. Dispatcher instructions significantly increased the provision of bystander CPR regardless of who the witnesses were. Neurologically favorable survival was increased by CPR in non-family-witnessed, but not in family-witnessed, OHCA patients. No difference in survival rate was observed between the cases provided with dispatcher instructions and those not provided with the instructions. Dispatcher instructions increased the frequency of bystander CPR, but did not improve the rate of neurologically favorable survival in patients with witnessed OHCA. Efforts to enhance the frequency and quality of resuscitation, especially by family members, are required for dispatcher-assisted CPR. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Simple renal cysts (SRC) are usually asymptomatic and do not require any kind of treatment. Laparoscopy is a reasonable minimally invasive surgical option for symptomatic cysts. Herein, we present the results of the laparoscopic technique for the treatment of symptomatic renal cysts performed in our institution. Between November 1992 and May 2006, 41 patients with symptomatic renal cysts were laparoscopically treated. The surgical techniques employed were transperitoneal and retroperitoneal. Demographic and surgical data was prospectively collected and analysis retrospectively performed. 41 patients were treated for symptomatic renal cysts in a fourteen year period. 23 (56%) women and 18 (44%) men, with a median age of 54 years. (Range 27-74 years.). All patients in the series were symptomatic. Pain was the most frequent symptom. Median cyst size was 10 cm. (range 5-16 cm.). Transperitoneal approach was performed in 24 patients (58%) and retroperitoneal in 17(42%). No differences were verified between these approaches. 16 lesions were located at the left renal unit, 24 in the right renal unit (54%) and one case presented bilateral lesions (3%). Median operative time was 52 min. (range 20-150 min.), median hospital stay was 42 hours (range 12-96 h.). 39 cysts (95.2%) were classified as Bosniak's type I lesions, 2 lesions (4.8%) were type II based on Bosniak's description. Final pathology confirmed every lesion as a simple renal cyst. There was only one relapse in the series. The latter was treated percutaneously. Laparoscopy is a feasible, safe and advantageous surgical therapeutic option for symptomatic renal cysts.

    Retinoblastoma (RB) is the most frequent solid tumor in the Instituto Nacional de Pediatría, México (INP). The bilateral presentation occurs in 25% of all patients. We present some epidemiological data of this form of the disease, in learn these epidemiological variables in our series. We reviewed the clinical charts from 1972 to 1994. We analyzed age, sex, timing of presentation of the second affected eye, positive family history, clinical staging, and the development of secondary malignancies. A total of 105 cases were detected from 412 RB total cases (25%). We observed a male predominance 1.6:1.0 p = 0.04 versus females. The clinical staging showed: retinal stage 9/102, ocular stage 58/102, orbital stage 26/102 and non classified 9/102 p < 0.00001. The asynchronous form is a rare presentation in our experience: 16/105 cases p = 0.00001 (15%). Only 16/105 patients had a positive family history of RB (15%). We found 2 of 105 cases with secondary malignancies (0.01%). The asynchronous form constitutes a rare presentation. We cannot explain the etiology for the high prevalence of bilateral disease. The frequency of secondary malignancies is lower than that reported in the literature.

    1. Small animals (rat and guinea pig) vagotomized in the neck die within a period of hours, the lungs showing extensive congestion and edema. 2. Tracheotomy permits appreciably longer survival with minimal lung changes approximating those seen in the control animals. 3. Intrathoracic vagotomy (sparing the recurrent laryngeal nerve) on one side, and cervical vagotomy on the other, permits almost indefinite survival (guinea pig and rabbit), unless laryngeal paralysis from the unilateral denervation produces respiratory obstruction (rat, guinea pig, and rabbit). 4. Pulmonary edema following bilateral vagotomy probably results primarily from respiratory obstruction. It is suggested that circulatory failure may also be a factor of some importance. The rôle of vagotomy itself is considered in relationship to these two phenomena. 5. The reaction of smaller animals to bilateral vagotomy, with regard to lung changes, apparently differs in no way from that of the larger animals, but is less readily demonstrated because of the smaller diameters of the air passages.

    A 35-year-old man presented with asymptomatic eruption on both forearms and lower aspects of the legs for 6 months. The lesions first appeared on his inner aspects of the wrist, the dorsal surface of the hands, and legs and progressed to involve proximal aspects of the extremities. There was no significant past history. On examination, multiple pearly white papules and depigmented atrophic plaques were found bilaterally on the flexors of the arms and the extensors of the legs. The lesions were arranged in a linear manner, following the lines of Blaschko (Figures 1 and 2). The surface of the atrophic plaques was notable for prominent telangiectasia, giving an erythematous appearance. The genitalia, oral cavity, palms, and soles were spared. Systemic examination was noncontributory. Lichen striatus and extragenital lichen sclerosus (ELS) were considered the differential diagnosis. Clinically, the age of the patient, the absence of scaling, and the presence of atrophic plaques and telangiectasia were in favor of ELS. A punch biopsy from an atrophic plaque was performed, and it revealed hyperkeratosis, atrophic epidermis, basal layer vacuolar degeneration, mild lymphocytic infiltration in the dermis, edema, and homogenization of collagen of the upper portion of the dermis (Figures 3 and Figure 4). Histopathologic findings were consistent with lichen sclerosus. A diagnosis of bilateral zosteriform ELS was made.

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    Speckle noise negatively affects medical ultrasound image shape interpretation and boundary detection. Speckle removal filters are widely used to selectively remove speckle noise without destroying important image features to enhance object boundaries. In this article, a fully automatic bilateral filter tailored to ultrasound images is proposed. The edge preservation property is obtained by embedding noise statistics in the filter framework. Consequently, the filter is able to tackle the multiplicative behavior modulating the smoothing strength with respect to local statistics. The in silico experiments clearly showed that the speckle reducing bilateral filter (SRBF) has superior performances to most of the state of the art filtering methods. The filter is tested on 50 in vivo US images and its influence on a segmentation task is quantified. The results using SRBF filtered data sets show a superior performance to using oriented anisotropic diffusion filtered images. This improvement is due to the adaptive support of SRBF and the embedded noise statistics, yielding a more homogeneous smoothing. SRBF results in a fully automatic, fast and flexible algorithm potentially suitable in wide ranges of speckle noise sizes, for different medical applications (IVUS, B-mode, 3-D matrix array US).

    Leprosy is an important cause of cranial nerve palsy in endemic areas where it may be seen in upto 17.6% patients. The authors herein describe a rare case of bilaterally symmetrical facial synkinesis with video documentation and modified blink reflex. A 35-year-old gentleman presented with numbness involving right half of his face for 8 months and abnormal stretching sensations over both sides of his nose for one and a half months. Sensory and motor involvement of the right trigeminal nerve was detected along with bilaterally symmetrical facial synkinesis involving orbicularis oculi and nasalis. R(1) and R(2) responses consistent with mis-reinnervation were recorded on the left-side using orbicularis oculi and nasalis muscles. Skin biopsy revealed acid-fast bacilli and sural nerve biopsy, the presence of granulomas. After 3 months of follow-up on WHO multi-drug therapy, an improvement in facial sensations was observed but without any change in facial synkinetic movements.

    Congenital renal anomalies (CRAs) detected in adults include horseshoe kidney (HK), crossed renal ectopia, and malrotation. Congenital renal anomalies are rare, and renal lesions associated with CRA are rarer. Thirteen patients (11 men and 2 women) were referred to our center with renal masses in the context of CRAs, which included HK (10 cases), crossed renal ectopia (2 cases), and a pelvic kidney (1 case). The mean age at diagnosis was 60 years (37-76 years). All patients were treated with open surgery; 10, partial nephrectomies; 4, radical nephrectomies; and 1, nephroureterectomy with division of the renal isthmus. Pathology ranged from benign (simple cortical cysts, chronic pyelonephritis with secondary hydronephrosis) to malignant (12 cases of renal cell carcinomas [RCCs] and 1 case of urothelial carcinoma). Two patients of HKs presented with bilateral renal masses. The size of the RCC ranged from 2.5 to 13 cm. There were 11 cases of clear cell RCC, 1 case of papillary RCC (type 1), and 1 case of urothelial carcinoma. All the cases of RCC had negative surgical margins. Follow-up available in all patients ranged from 1 month up to 49 months. None of the patients developed any locoregional recurrences or distant metastases. In this patient cohort, the most common congenital anomaly associated with RCC is HK. All tumors behaved in an indolent fashion with prognosis related to pathologic tumor stage. Partial nephrectomy is a safe and effective procedure in appropriately selected patients.

    We are reporting a case of bilateral eosinophilic mastitis which is rare and hardly heard. It is a mimicker of carcinoma breast both clinically & radiologically. A 30 years old non diabetic female presented with bilateral breast lumps with history of rhinitis off & on and peripheral eosinophilia. Mammography was suspicious while ultrasonography was diagnostic of bilateral mastitis. Aspiration cytology exhibited inflammatory lesion rich in eosinophils. Histopathology revealed the diagnosis of eosinophilic mastitis. Eosinophilic infiltration of the breast is a rare manifestation of tissue involvement in peripheral eosinophilia and bilateralism is even rarer.

    Cochlear implantation is a standard method of hearing rehabilitation among patients with severe to profound bilateral sensorineural hearing loss. In recent years there have been an increasing number of studies showing superior hearing with bilateral cochlear implantation in comparison with a unilateral procedure. In this study we present our experience with 15 patients, children and adults, who had bilateral cochlear implant surgery. Speech perception test results demonstrated a hearing benefit in bilateral cochlear implantation in comparison with a unilateral device, mainly by improvement in the identification of speech in noise tests.

  12. Bilateral supernumerary kidneys: how much is too much?

    2014-01-01

    A middle aged African-American woman with a stable history of carnitine palmitoyl transferase II (CPT II) deficiency presented with myalgias for 1 week. Physical examination and laboratory findings were consistent with severe sepsis secondary to pyelonephritis leading to rhabdomyolysis. Subsequent CT of the abdomen revealed bilateral supernumerary kidneys with non-obstructive calculi within the supernumerary kidneys. Abnormal ureteral development of the supernumerary kidneys likely led to an increased risk for urinary tract infections (UTIs) and renal calculi resulting in pyelonephritis. The stress of this infection overwhelmed the muscle CPT II enzyme load, putting her in a state of rhabdomyolysis. In addition to fluids and antibiotics, she was provided a diet rich in carbohydrates and low in fats so as to limit long-chain fatty acid oxidation. Supernumerary nephrectomy was not considered during this admission. During follow-up, she developed obstructive ureteral calculi requiring placement of a right-sided ureteral stent. PMID:24692375

    Sonographic findings of renal medullary hyperechogenicity have been observed in the neonate in association with severe perinatal renal injury, kidney malformations or nephrocalcinosis, and, rarely, in newborn infants with transient renal failure. The aim of the study was to describe the entity of neonatal transient renal failure with renal medullary hyperechogenicity (NTRFMH). We studied nine term neonates, born between August 1999 and February 2004 in our institution (0.1% of the live born infants), who developed transient renal dysfunction after birth, and in whom renal sonograms showed bilateral medullary hyperechogenicity. Seven of the infants (78%) had anuria until 30-45 hours of age, and two (22%) had oliguria. Peak serum creatinine levels ranged between 0.61 and 1.62 mg/dL (mean: 1.09+/-0.27 mg/dL) at 2-3 days of life. Additional findings included proteinuria in nine infants (100%), uric acid crystalluria in seven (78%), hyperuricemia in four (44%), and hypertension in one (11%). Hyperuricosuria was demonstrated in one out of the seven patients in whom this parameter was determined. Urinary excretion rates of calcium, phosphorus and oxalic acid were normal, as were urinary levels of amino acids and organic acids. Full clinical recovery accompanied by normalization of all laboratory parameters was observed in all infants by 4-6 days of life. Subsequent follow-up showed normal renal function, no urinary abnormalities, and normal renal sonograms in all infants. Our summary of the nine infants with NTRFMH reported on here and a review of 19 cases of this condition reported in the literature reveal a not-so-rare entity of unclear etiology, but excellent prognosis. Physicians caring for neonates should be aware of this benign and transient condition.

    The purpose of this study was to assess the incidence of spontaneous renal artery dissection (SRAD) as a cause of acute renal infarction, and to evaluate the clinical and multidetector computed tomography (MDCT) findings of SRAD. From November 2011 to January 2014, 35 patients who were diagnosed with acute renal infarction by MDCT were included. We analyzed the 35 MDCT data sets and medical records retrospectively, and compared clinical and imaging features of SRAD with an embolism, using Fisher's exact test and the Mann-Whitney test. The most common cause of acute renal infarction was an embolism, and SRAD was the second most common cause. SRAD patients had new-onset hypertension more frequently than embolic patients. Embolic patients were found to have increased C-reactive protein (CRP) more often than SRAD patients. Laboratory results, including tests for lactate dehydrogenase (LDH) and blood urea nitrogen (BUN), and the BUN/creatinine ratio (BCR) were significantly higher in embolic patients than SRAD patients. Bilateral renal involvement was detected in embolic patients more often than in SRAD patients. MDCT images of SRAD patients showed the stenosis of the true lumen, due to compression by a thrombosed false lumen. None of SRAD patients progressed to an estimated glomerular filtration rate < 60 mL/min/1.73 m² or to end-stage renal disease during the follow-up period. SRAD is not a rare cause of acute renal infarction, and it has a benign clinical course. It should be considered in a differential diagnosis of acute renal infarction, particularly in patients with new-onset hypertension, unilateral renal involvement, and normal ranges of CRP, LDH, BUN, and BCR.

    To report on our experience in conservative surgery for renal cell carcinoma, pointing at indications, surgical techniques and results. We also make a review of the literature. From 1975 until 1997, 231 patients underwent surgical treatment of renal cell carcinoma. In 17 cases conservative surgery was done. 11 patients were male and 6 female, with age range 33-78 years. Polar nephrectomy was done in 4 cases and tumorectomy in 13 cases. The indication was elective in 10 cases, and imperative in 7 due to: 4 bilateral carcinomas, 1 chronic renal failure, 1 von Hippel Lindau disease and 1 tumor associated with surgical lithiasis of the kidney. 58.8% of the patients did not have clinical symptoms and the diagnose was incidental. The average size of the tumors was 3.8 cm. The pathological stage was: 3 cases T1N0M0 and 12 T2N0M0. All the T1 cases had an incidental diagnose. The complications were: 1 urinary fistula, 1 haematoma, and 1 case of postoperative fever. All these complications were solved in a conservative way. We had tumoral recurrence in one patient affected with von Hippel Lindau disease. It appeared 4 years after the surgical procedure and required radical nephrectomy. One patient died 24 months after surgery because of causes not related with renal tumor. The rest of the patients are alive, with no tumoral recurrence, within an average follow-up of 49.6 months. None of the patients needed dialysis. Our experience, though not great is enough to demonstrate the benefits of conservative surgery for renal cell carcinoma. Partial nephrectomy in selected patients and with the appropriate surgical technique offers short-term results similar to those obtained with radical nephrectomy. It is indispensable to make the resection and intraoperative pathological study of a margin of renal parenchyma surrounding the tumor, and also to examine the whole surface of the kidney to search for satellite tumoral nodules. It is very important to do a close follow up of these

    According to the National Hip Fracture Database, over 64,000 patients were admitted with a hip fracture across England, Wales, and Northern Ireland in 2013, but very few are bilateral, and there are no current cases in the literature of bilateral neck of femur fractures in a patient with bilateral below-knee amputations. We present a case of a 69-year-old bilateral below-knee amputee male admitted to the emergency department with bilateral hip pain and radiological evidence of bilateral displaced neck of femur fractures. The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

    2015-04-01

    Review the indications, outcomes, and consequences of bilateral adrenalectomy (BLA) in patients with Cushing's disease. A literature review was performed. The primary therapy for Cushing's disease is surgery, with medical therapy and radiation therapy relegated to an adjuvant role. BLA is indicated in cases of persistent disease following pituitary surgery or in situations where rapid normalization of hypercortisolism is required. When performed via the laparoscopic approach, BLA is associated with a significantly reduced morbidity compared to the traditional, open approach. Following BLA, patients are at risk for adrenal crisis and the concern of Nelson's syndrome. However, BLA leads to a rapid resolution of the signs and symptoms of CS and leads to an improved long-term quality of life. BLA should be considered in the treatment algorithm for patients with persistent CD after failed pituitary surgery, especially in patients who have severe consequences of hypercortisolism or desire pregnancy.

    This paper proposes a bilateral fitting subtracting confocal microscopy (BFSCM) based on the optical arrangement of conventional confocal microscopy (CM). BFSCM first uses the data in both sides of a confocal axial response curve, which are very sensitive to the axial position of the sample, for respective linear fitting to obtain two fitting straight lines, and then obtains a difference confocal line by subtraction of the two fitting lines. Finally, it calculates the zero position of the difference confocal line to precisely capture the focus position of the confocal system, and thereby achieving a high-precision measurement of the 3D structure of the sample. The theoretical analyses and experiments indicate that BFSCM can improve the axial resolution, and has anti-interference capability and focusing ability with bipolar absolute zero point tracking, while it does not change the structure and lateral resolution of CM. BFSCM provides a novel method for the improvement of CM axial resolution.

    Iatrogenic Cushing syndrome induced by oral and parenteral corticosteroid administration is a well-known complication, and necessary precautions have to be taken. Cushing syndrome, however, following treatment with glucocorticoid-containing eye drops is a very rare complication. To the best of our knowledge, there have been only four reported cases in the literature. Herein, we present an infant boy who developed Cushing syndrome after receiving dexamethasone-containing eye drops after bilateral cataract extraction to prevent postoperative inflammatory complications. At the age of 5 months, after approx. 3 months of dexamethasone therapy, the patient presented with cushingoid facies, nephrocalcinosis and failure to grow. Iatrogenic Cushing syndrome was diagnosed and dexamethasone-containing eye drops were reduced and eventually stopped. Follow-up examinations revealed catch-up growth. Ocularly administered corticosteroids may have substantial systemic side effects in infants.

    Intravascular migration of bullets and other foreign bodies is a rare but known complication of penetrating trauma. Missile embolization can represent a diagnostic challenge because it may present in various and unexpected ways. We present the case of a 54-year-old female who sustained shotgun pellet emboli to the pulmonary arteries following a left upper extremity gunshot wound and related vascular surgery. The case illustrates bilateral embolization, and the embolic events occurred following surgery. Embolization should be considered in evaluating patients with gunshot wounds, particularly if there are anomalous symptoms or the projectile is not found in the original, or expected, location. Close attention to the location of the foreign bodies on serial radiographs may reveal the diagnosis of intravascular embolization. PMID:22690290

    Frequency of pregnancy among childbearing age women with end-stage renal disease (ESRD) undergoing long-term periodic dialysis ranges from 1% to 7%. Although pregnancy in dialysis women with ESRD is considered a largely high-risk pregnancy, occurrence of successful pregnancy is not impossible with success rates approaching 70%. Rates of successful pregnancy are greatly impacted by early pregnancy diagnosis and preserved residual renal functions. Herein, to the best of our knowledge, we report the first case of successful pregnancy (despite late diagnosis at 14 weeks of gestation) in a 31-year-old peritoneal dialysis patient with bilateral nephrectomy and no whatsoever preserved residual renal function. Moreover, a literature review on pregnancy in dialysis patients is presented. PMID:24198990

    Background Simultaneously developed bilateral primary spontaneous pneumothorax (BPSP) is an indication for thoracic surgery of both sides. Recently, we have reported a new technique for BPSP, which is ipsilateral apicoposterior transmediastinal (TM) bullectomy of both sides using video-assisted thoracoscopic surgery (VATS), and we compared this TM VATS with bilateral sequential (BS) VATS for BPSP. Materials and Methods From June 2003 to May 2014, 11 and 14 patients were performed VATS TM and BS bullectomy for BPSP, respectively. We reviewed the medical records and compared the clinical data between the two groups. For TM group, we first performed the right VATS bullectomy and approached through the apicoposterior mediastinal region for contralateral VATS. In the other group, conventional BS VATS bullectomy was performed in the lateral decubitus position change. Results The mean follow-up was 62.0 ± 32.6 months. No mortality and major complications were observed. The operative time (68.18 ± 24.93 vs. 96.07 ± 37.73, p = 0.046), duration of left pleural drainage (1.00 ± 0.45 vs. 3.21 ± 1.37, p = 0.000), and length of hospital stay (3.82 ± 1.54 vs. 4.93 ± 1.07, p = 0.044) were significantly shorter in the TM group than in the BS group. No significant differences were seen in duration of general anesthesia, total number of wedge resections and endostaplers used in both lungs, duration of right drainage, and postoperative recurrence. Conclusion The TM VATS approach may be a safe and feasible modality for BPSP. It may decrease the operative time, patients inconvenience such as bilateral multiple wounds and longstanding placement of chest tubes, and decrease the hospital stay compared with the BS VATS approach.

    Xanthogranulomatous orchitis (XGO) is a rare chronic inflammatory process characterized by destruction of tissue that is replaced by an outstanding cellular infiltrate of lipid-laden macrophages. To date, 20 cases of this process have been reported previously. We present herein the case of a 55-year-old man who had sustained complete tetraplegia at C-6 level and neuropathic bladder for 21 years. After repeated episodes of urinary tract infection, the patient developed a bilateral XGO and a right xanthogranulomatous epididymitis (XGE) that were treated with bilateral orchiepididymectomy. To our knowledge, a bilateral XGO has not yet been reported. Repeated episodes of high-pressure urinary reflux along the vas deferens during dyssynergic voiding possibly led to retrograde extension from the urinary tract by common urinary pathogens and development of bilateral XGO and right XGE. Since tissue destruction is a feature of this process, curative treatment required antibiotic therapy followed by bilateral excision of testes and epididymes.

    Upper urinary tract occlusion is well recognized in patients with chronic ketamine abuse. The mechanism is generally unknown, but the ulcerative cystitis contracture may be responsible for obstruction. We present the first reported use of the Resonance metallic ureteric stent in the management ureteric obstruction caused by ketamine-induced uropathy. A 31-year-old lady with one-year history of recreational ketamine abuse presented with symptoms related to drug-induced ulcerative cystitis over twelve-months. She presented with acute renal failure with bilateral pyonephrosis and sepsis, and was initially treated with bilateral nephrostomy insertions and antegrade stenting. The J stents recovered the renal function, but the patient suffered from recurrent urinary tract infections (UTI's) with the prosthesis in-situ. The patient successfully underwent bilateral insertion of 12cm 6.0 French Cook Resonance metallic ureteric stents. One year following the placement of the metallic stents, the patient maintained optimal renal function with no episode of UTI. Ketamine induced uropathy is a well documented complication of chronic drug-induced ulcerative cystitis. The mechanical strength and inert property of metallic ureteric stents make it an ideal device to manage this problematic benign cause of ureteric obstruction. This is the first reported case of therapeutic bilateral metallic ureteric stents in the management of patients with ketamine induced uropathy with one year follow up. Copyright © 2015 The Authors.

    Introduction. Interferon is a glycoprotein produced by assigned cells of immune system. It has been used in many different diseases. Although flu-like syndrome, myalgia, rash, hypotension, thrombocytopenia and peripheral neuropathy due to interferon use are encountered frequently, ocular side effects are rare, generally mild and transient. Case Report. 47-year-old female patient, presented with a mass lesion in right renal pelvis. Right radical nephrectomy was applied and the histopathological examination was consistent with papillary renal cell carcinoma. Interferon alpha treatment was started subcutaneously at the dose of 5 MIU/3 times in a week. Four weeks after the interferon therapy, suddenly bilateral visual loss developed. We discussed the diagnosis, followup, and treatment of the patient who developed irreversible ischemic optic neuropathy and had no previous known primary systemic disease to cause this condition. Conclusion. We suggest that patients should be screened for risk factors causing optic ischemic neuropathy, before interferon therapy. Although there was no adequate information in the literature for the followup, patients should be monitorized before, 1 month after, and 2 months after the treatment. And if there is no complication, we suggest that they should be followed up at 3-month intervals.

    The purpose of this study was to determine if simultaneous bilateral carpal tunnel release (CTR) is a cost-effective strategy compared with bilateral staged CTR for the treatment of bilateral carpal tunnel syndrome. A decision analytic model was created to compare the cost effectiveness of three strategies (ie, bilateral simultaneous CTR, bilateral staged CTR, and no treatment). Direct medical costs were estimated from 2013 Medicare reimbursement rates and wholesale drug costs in US dollars. Indirect costs were derived from consecutive patients undergoing unilateral or simultaneous bilateral CTR at our institution and from national average wages for 2013. Health state utility values were derived from a general population of volunteers using the Short Form-6 dimensions (SF-6D) health questionnaire. Both surgical strategies were cost effective compared with the no-treatment strategy. Bilateral simultaneous CTR had lower total costs and higher total effectiveness than bilateral staged CTR, and had an incremental cost-effectiveness ratio of $921 per quality-adjusted life year compared with the no-treatment strategy. The conclusions of the analysis remained unchanged though all sensitivity analyses, displaying robustness against parameter uncertainty. Surgical management is cost effective for the treatment of bilateral carpal tunnel syndrome. Bilateral simultaneous CTR, however, has lower total costs and higher total effectiveness compared with bilateral staged CTR. Economic and Decision Analysis I.

    Cigarette smoking causes cardiovascular disease and is associated with poor kidney function in individuals with diabetes mellitus and primary kidney diseases. However, the association of smoking on patients with atherosclerotic renal artery stenosis has not been studied. The current study utilized data from the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL, NCT00081731) clinical trial to evaluate the effects of smoking on the risk of cardio-renal events and kidney function in this population. Baseline data showed that smokers (n = 277 out of 931) were significantly younger at enrollment than non-smokers (63.3±9.1 years vs 72.4±7.8 years; p<0.001). In addition, patients who smoke were also more likely to have bilateral renal artery stenoses and peripheral vascular disease (PVD). Longitudinal analysis showed that smokers experienced composite endpoint events (defined as first occurrence of: stroke; cardiovascular or renal death; myocardial infarction; hospitalization for congestive heart failure; permanent renal replacement; and progressive renal insufficiency defined as 30% reduction of GFR from baseline sustained for ≥ 60 days) at a substantially younger age compared to non-smokers (67.1±9.0 versus 76.1±7.9, p<0.001). Using linear regression and generalized linear modeling analysis controlled by age, sex, and ethnicity, smokers had significantly higher cystatin C levels (1.3±0.7 vs 1.2±0.9, p<0.01) whereas creatinine and estimated glomerular filtration rate (eGFR) were not different from non-smokers. From these data we conclude that smoking has a significant association with deleterious cardio-renal outcomes in patients with renovascular hypertension. PMID:28306749

    Despite significant clinical interest in renal denervation as a therapy, the role of the renal nerves in the physiological regulation of renal blood flow (RBF) remains debated. We hypothesized that the renal nerves physiologically regulate beat-to-beat RBF variability (RBFV). This was tested in chronically instrumented, healthy rabbits that underwent either bilateral surgical renal denervation (DDNx) or a sham denervation procedure (INV). Artifact-free segments of RBF and arterial pressure (AP) from calmly resting, conscious rabbits were used to extract RBFV and AP variability for time-domain, frequency-domain, and nonlinear analysis. Whereas steady-state measures of RBF, AP, and heart rate did not statistically differ between groups, DDNx rabbits had greater RBFV than INV rabbits. AP-RBF transfer function analysis showed greater admittance gain in DDNx rabbits than in INV rabbits, particularly in the low-frequency (LF) range where systemic sympathetic vasomotion gives rise to AP oscillations. In the LF range, INV rabbits exhibited a negative AP-RBF phase shift and low coherence, consistent with the presence of an active control system. Neither of these features were present in the LF range of DDNx rabbits, which showed no phase shift and high coherence, consistent with a passive, Ohm's law pressure-flow relationship. Renal denervation did not significantly affect nonlinear RBFV measures of chaos, self-affinity, or complexity, nor did it significantly affect glomerular filtration rate or extracellular fluid volume. Cumulatively, these data suggest that the renal nerves mediate LF renal sympathetic vasomotion, which buffers RBF from LF AP oscillations in conscious, healthy rabbits. PMID:26538235

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing’s syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88–100% and 67–100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50–70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    Total and separate renal functions were evaluated in 40 patients with cystinuria. The average duration of the renal stone disease was 26 years (range 1-53). The patients had been subjected to a stone-preventing regimen composed of increased fluid intake, urinary alkalinization and treatment with a sulphydryl compound, tiopronin or D-penicillamine, for an average of 11.7 years (range 1-24). Urinary cystine concentration was determined regularly to monitor the treatment. All patients were examined with gamma camera renography and an assessment of glomerular filtration rate (GFR), and early and late renographic results could be compared in 30 patients. The early renographic evaluation showed that 43% of binephric patients (13/30) had an abnormal relative renal function (RRF) before the start of the stone-preventing treatment. At the late evaluation, 50% of binephric patients (17/34) had an abnormal RRF, while 30% of all patients (12/40) had a GFR below the age-related normal range. Thirty percent of 74 evaluated kidneys (22/74) had a separate GFR below an estimated age-related normal range. At the late evaluation only 30% of the patients had functionally unaffected kidneys with both normal GFR and bilateral normal renography. There was, however, no case with terminal renal failure. The separate GFR of kidneys with a history of staghorn stones was significantly lower than for kidneys without that special type of stones, but otherwise there was no relationship between renal functional impairment and other estimates of the activity of the renal stone disease. In conclusion, impairment of renal function is common in patients with stone-forming cystinuria. Stone-preventive treatment appears to be effective in preserving renal function. The high frequency of renal functional impairment justifies close surveillance of this group of patients. By renographic examination, unilateral changes in renal function can be detected at an early stage and patients at risk for further

    Unilateral and bilateral sudden sensorineural hearing loss represent different disease entities. The unilateral condition is more common and predominantly idiopathic, and up to 65 per cent of patients spontaneously recover hearing. Conversely, the bilateral condition is rare, mostly associated with serious systemic conditions, and has a higher prevalence of morbidity and mortality. A literature search using the PubMed database was conducted using the MeSH terms 'sudden', 'bilateral' and 'sensorineural hearing loss'. One hundred and three reported cases of bilateral sudden sensorineural hearing loss were identified. The condition is most often associated with toxic, autoimmune, neoplastic and vascular conditions. A younger age of onset, with a bimodal age distribution, was seen for bilateral sudden sensorineural hearing loss, compared with the unilateral condition. Patients with the bilateral condition had more profound hearing loss, with poorer recovery and a 35 per cent mortality rate. Vestibular symptoms were also less common than in the unilateral condition. The presentation of bilateral sudden onset sensorineural hearing loss is a medical emergency requiring thorough and urgent investigation to exclude life-threatening and reversible conditions.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    This study adopted an inner ear test battery and MR imaging in patients with bilateral sudden sensorineural hearing loss (SSNHL) to investigate their causes, disease extent, and evaluate hearing outcome. From 1995 to 2014, 16 patients with bilateral SSNHL received audiometry, caloric test and MR imaging. Vestibular-evoked myogenic potential (VEMP) test was added to the test battery after 2000. Percentages of abnormal mean hearing level (MHL), cervical VEMP test, ocular VEMP test, and caloric test in patients with bilateral SSNHL were 100% (32/32), 100% (12/12), 100% (4/4), and 81% (26/32), respectively, implying that not only the cochlear part but also the vestibular part was severely affected in both ears. Causes of bilateral SSNHL were neoplasm in 5 patients, stroke in 5, meningitis in 1, and unknown in 5. Post-treatment MHL did not significantly differ from pre-treatment MHL indicating poor hearing outcome. Seven patients (44%) had passed away within 5years after onset, 2 patients were lost, and 7 patients survived. Via MR imaging, causes of bilateral SSNHL were identified for 69% of cases. Both cochlear and vestibular endorgans/afferents were identified to be severely affected bilaterally by the vestibular test battery and resulted in poor hearing outcome. A high mortality rate (44%) indicates that bilateral SSNHL is an ominous sign for a more sinister underlying disease. Copyright © 2016 Elsevier B.V. All rights reserved.

  13. Therapy-resistant nephrolithiasis following renal artery coil embolization

    PubMed Central

    2013-01-01

    Background Transcatheter renal artery embolization is an effective and minimally invasive treatment option for acute renal bleeding. Early post-interventional complications include groin hematoma, incomplete embolization, coil misplacement and coil migration. Late complications are rare and mostly related to coil migration. Case presentation A 22-year-old woman with a history of recurrent stone disease and a lumbal meningomyelocele underwent bilateral open pyelolithotomy for bilateral staghorn calculi. Post-operatively, acute hemorrhage of the left kidney occurred and selective arterial coil embolization of a lower pole interlobular renal artery was performed twice. Four years after this intervention the patient presented with a new 15.4 mm stone in the lower calyx of the left kidney. After two extracorporeal shock wave lithotripsy treatments disintegration of the stone was not detectable. Therefore, flexible ureterorenoscopy was performed and revealed that the stone was adherent to a partially intraluminal metal coil in the lower renal calyx. The intracalyceal part of the coil and the adherent stone were successfully removed using the holmium laser. Conclusion Therapy-resistant nephrolithiasis was caused by a migrated metal coil, which was placed four years earlier for the treatment of acute post-operative renal bleeding. Renal coils in close vicinity to the renal pelvis can migrate into the collecting system and trigger renal stone formation. Extracorporeal shock wave lithotripsy seems to be inefficient for these composite stones. Identification of these rare stones is possible during retrograde intrarenal surgery. It also enables immediate stone disintegration and removal of the stone fragments and the intraluminal coil material. PMID:23758632

    The sternocleidomastoid muscle shows a wide range of variations including supernumerary muscular heads. We found a rare variation in the sternocleidomastoid muscle with bilateral supernumerary heads in a 67-year-old Korean male cadaver. Bilateral four muscle bellies were recorded: two sternomastoids, one cleido-occipital and one cleido-mastoid occipital on the right side, and one sternomastoid, one cleido-occipital and two cleido-mastoids on the left side. The variation of bilateral four heads on sternocleidomastoid muscle is important to surgeons and anesthetists for clinical using.

We report a case of 14-year-old girl who presented with dyspnea, bipedal edema, loss of weight, and easy fatigability for three months. She was being treated for DCM for the same duration. Clinical examination revealed absence of both upper limb pulses. Echocardiography revealed features of DCM with severe biventricular dysfunction (ejection fraction 30%). Computed tomography angiogram confirmed the diagnosis of TA and revealed the presence of bilateral renal artery stenosis. Bilateral renal angioplasty was done, and immunosuppressant therapy with oral prednisolone and weekly oral methotrexate was started.

    A 51-year-old woman on hemodialysis for chronic renal failure complained of visual loss in her right eye. Right optic disc edema was observed on fundus examination. An arteritic optic neuropathy was suspected. However, a first biopsy did not reveal any inflammatory cells. Two months later, the patient experienced sudden visual loss in her left eye and presented with necrotic cutaneous lesions at the distal phalanges of several fingers of the right hand. Necrotic lesions also appeared on the inner aspect of the thighs. Biopsy of the cutaneous lesions revealed calcification in the wall of a small artery. A new biopsy of the temporal artery showed large calcium deposits in the artery's tunica media. The diagnosis of optic neuropathy secondary to calciphylaxis was made. A temporal artery biopsy should be repeated if the first one is inconclusive. An early diagnosis leading to appropriate treatment may help to prevent an irreversible loss of vision in these patients.

    Life threatening conditions characterized by renal ischemia/reperfusion (RIR) such as kidney transplantation, partial nephrectomy, renal artery angioplasty, cardiopulmonary bypass and aortic bypass surgery, continue to be among the most frequent causes of acute renal failure. The current study investigated the possible protective effects of tadalafil alone and in combination with diltiazem in experimentally-induced renal ischemia/reperfusion injury in rats. Possible underlying mechanisms were also investigated such as oxidative stress and inflammation. Rats were divided into sham-operated and I/R-operated groups. Anesthetized rats (urethane 1.3g/kg) were subjected to bilateral ischemia for 30min by occlusion of renal pedicles, then reperfused for 6h. Rats in the vehicle I/R group showed a significant (p˂0.05) increase in kidney malondialdehyde (MDA) content; myeloperoxidase (MPO) activity; TNF-α and IL-1β contents. In addition significant (p˂0.05) increase in intercellular adhesion molecule-1(ICAM-1) content, BUN and creatinine levels, along with significant decrease in kidney superoxide dismutase (SOD) activity. In addition, marked diffuse histopathological damage and severe cytoplasmic staining of caspase-3 were detected. Pretreatment with combination of tadalafil (5mg/kg bdwt) and diltiazem (5mg/kg bdwt) resulted in reversal of the increased biochemical parameters investigated. Also, histopathological examination revealed partial return to normal cellular architecture. In conclusion, pretreatment with tadalafil and diltiazem combination protected against RIR injury.

    Abstract Type 2 diabetes mellitus (T2DM) is a group of metabolic diseases of multiple etiologies. Although great progress has been made, researchers are still working on the pathogenesis of T2DM and how to best use the treatments available. Aside from several novel pharmacological approaches, catheter-based sympathetic renal denervation (RDN) has gained a significant role in resistant hypertension, as well as improvements in glycemic control in T2DM. In this article, we will summarize herein the role sympathetic activation plays in the progression of T2DM and review the recent clinical RDN experience in glucose metabolism. We performed systematic review in online databases, including PubMed, EmBase, and Web of Science, from inception until 2015. Studies were included if a statistical relationship was investigated between RDN and T2DM. The quality of each included study was assessed by Newcastle–Ottawa scale score. To synthesize these studies, a random-effects model or a fixed-effects model was applied as appropriate. Then, we calculated heterogeneity, performed sensitivity analysis, tested publication bias, and did meta-regression analysis. Finally, we identified 4 eligible articles. In most studies, RDN achieved via novel catheter-based approach using radiofrequency energy has gained a significant role in resistant hypertension, as well as improvements in glycemic control in T2DM. But the DREAMS-Study showed that RDN did not change median insulin sensitivity nor systemic sympathetic activity. Firstly, the current published studies lacked a proper control group, along with the sample capacity was small. Also, data obtained in the subgroups of diabetic patients were not separately analyzed and the follow-up period was very short. In addition, a reduction in blood pressure accounts for the improvements in glucose metabolism and insulin resistance cannot be excluded. If the favorable result of better glucose metabolism is confirmed in large-scale, randomized studies

    Women with renal disease who conceive and continue a pregnancy are at significant risk for adverse maternal and fetal outcomes. Risk is inversely related to the degree of renal insufficiency. Pregnancy-induced changes in the urinary tract can temporarily increase renal function compromise, such as nephrosis, but most often results in no net increase in dysfunction. Common complications of pregnancy--such as hypertension and hypovolemia--can be associated with acute renal injury or aggravation of pre-existing disease.

    The purpose of this study was to evaluate the bilateral coordination in children and adolescents with visual impairments aged 7 to 18 years in comparison to their sighted peers. An additional objective was to identify the influence of sex and age on bilateral coordination. Seventy-five individuals with congenital severe visual impairment (40 girls and 35 boys) comprised the visually impaired group. The Sighted group comprised 139 youth without visual impairment. Subtest 4 of the Bruininks-Oseretsky Test of Motor Proficiency was administered to test bilateral coordination. To analyze the effect of the independent variables in the results obtained in the Subtest 4, four linear regression models were applied according to group and sex. The results indicated that severe visual impairment and lack of visual sensation had a negative effect on the development of participants' bilateral coordination, which however did not depend on sex or age. © The Author(s) 2016.

    Antenatal renal vein thrombosis is a rarely described diagnostic finding, with variable consequences on kidney function. We present the case of an affected fetus, born at 35-week gestation, with intrauterine oligohydramnios and two small kidneys. A renal ultrasound carried out after birth confirmed the presence of prenatal abnormalities. Renal vein thrombosis was not diagnosed at the time. The baby died 20 days later of kidney failure, metabolic acidosis, and polypnea with severe hypotrophy. Autopsy revealed atrophied kidneys and adrenal glands. The vena cava had thrombosis occupying most of its length. The right renal vein was normal, while the left renal vein was threadlike and not permeable. Histologically, there was necrosis of the left adrenal gland with asymmetrical bilateral renal impairment and signs of ischemic and hemorrhagic lesions. A review of thrombophilia was carried out and a heterozygous mutation in Factor V was found in both the mother and the child. PMID:26124971

    Postnatal imaging findings were reviewed in 130 neonates and young infants referred for imaging evaluation of antenatally detected renal abnormalities. All children underwent voiding cystourethrography and upper urinary tract imaging with sonography and/or renal scintigraphy. Vesicoureteral reflux was present in 49 patients (38%) and was bilateral in 24. All grades of reflux were observed. Reflux occurred in 41 of 98 neonates (42%) in whom postnatal imaging revealed persistent upper tract abnormalities (eg, hydronephrosis, cysts, renal agenesis) and in eight of 32 (25%) with normal findings at postnatal sonography and/or renal scintigraphy. Reflux was the single most common urologic diagnosis and was the only postnatal abnormality in 12 patients (9%). The authors conclude that neonates with antenatally detected hydronephrosis should be routinely screened for reflux with voiding cystography. Detection and aggressive management of reflux in the asymptomatic neonate in whom renal growth and function are unimpaired theoretically offer the best opportunity for preventing renal injury later in childhood.

    We report a case of bilateral pneumolabyrinth presenting as sudden, bilateral deafness, without temporal bone fracture, after a fall. A 49-year-old man presented with sudden, bilateral deafness and whirling vertigo, without any other neurological manifestations. Temporal bone computed tomography clearly demonstrated the presence of air in the vestibule and cochlea on both sides. However, there was no definite fracture line, ossicular chain anomaly or soft tissue density in the temporal bone or middle-ear cavity. The patient was treated conservatively. Unfortunately, there was no improvement in his hearing. Pneumolabyrinth is an uncommon condition in which air is present in the vestibule or cochlea. It is rarely found, even with fractures violating the otic capsule or with transverse fractures of the temporal bone. In addition, its bilateral occurrence is extremely rare. In this article, we describe a case of bilateral pneumolabyrinth presenting as sudden, bilateral deafness, without temporal bone fracture, an occurrence which has not previously been reported.

    Bilateral facial palsy is a rare clinical entity caused by myriad disparate conditions requiring different treatment paradigms. Lyme disease, Guillain-Barré syndrome, and leukemia are several examples. In this article, the authors describe the cause, the initial diagnostic approach, and the management of long-term sequelae of bilateral paralysis that has evolved in the authors' center over the past 13 years. A chart review was performed to identify all patients diagnosed with bilateral paralysis at the authors' center between January of 2002 and January of 2015. Demographics, signs and symptoms, diagnosis, initial medical treatment, interventions for facial reanimation, and outcomes were reviewed. Of the 2471 patients seen at the authors' center, 68 patients (3 percent) with bilateral facial paralysis were identified. Ten patients (15 percent) presented with bilateral facial paralysis caused by Lyme disease, nine (13 percent) with Möbius syndrome, nine (13 percent) with neurofibromatosis type 2, five (7 percent) with bilateral facial palsy caused by brain tumor, four (6 percent) with Melkersson-Rosenthal syndrome, three (4 percent) with bilateral temporal bone fractures, two (3 percent) with Guillain-Barré syndrome, one (2 percent) with central nervous system lymphoma, one (2 percent) with human immunodeficiency virus infection, and 24 (35 percent) with presumed Bell palsy. Treatment included pharmacologic therapy, physical therapy, chemodenervation, and surgical interventions. Bilateral facial palsy is a rare medical condition, and treatment often requires a multidisciplinary approach. The authors outline diagnostic and therapeutic algorithms of a tertiary care center to provide clinicians with a systematic approach to managing these complicated patients.

    Primary hyperoxaluria type 1 (PH1) is a rare liver enzymatic defect that causes overproduction of plasma oxalate. Accumulation of oxalate in the kidney and subsequent renal failure are fatal to PH1 patients often in pediatric age. Combined liver and kidney transplantation is the therapy of choice for end-stage renal disease due to PH1. Levels of plasma oxalate remain elevated for several months after liver transplantation, as the residual body oxalate is slowly excreted. Patients with persistent hyperoxaluria after transplant often require hemodialysis, and accumulation of residual oxalate in the kidney can induce graft dysfunction. As the native kidneys are the main target of calcium oxalate accumulation, we postulated that removal of native kidneys could drastically decrease total body oxalate levels after transplantation. Here, we report a case of bilateral nephrectomy at the time of combined liver-kidney transplantation in a pediatric PH1 patient. Bilateral nephrectomy induced a rapid decrease in plasma oxalate to normal levels in less than 20 days, compared to the several months reported in the literature. Our results suggest that removal of native kidneys could be an effective strategy to decrease the need for hemodialysis and the risk of renal dysfunction after combined liver-kidney transplantation in patients with PH1.

    Renal angiomyolipoma is common in the tuberous sclerosis complex (TSC), the classic features of which are facial angiofibroma, seizures, and mental retardation. We report a family with three affected members demonstrating the wide spectrum of TSC-associated lesions ranging from asymptomatic findings to life-threatening complications. The predominant symptoms of the index patient were hypertension and mild renal insufficiency at age 48, resulting in end-stage renal failure at age 63 due to giant bilateral angiomyolipoma of the kidneys. The two TSC-affected siblings had died years previously, one from pulmonary lymphangioleiomyomatosis and the other during an epileptic state; the latter had situs inversus totalis as another remarkable finding. The diagnosis of TSC may be overlooked if CNS symptoms are absent and if cutaneous lesions are masked by cosmetic procedures, as occurred in the index case. Chronic renal failure due to angiomyolipoma is not widely known to clinical nephrologists, but develops in approximately 15% of TSC patients. Displacement of functional renal parenchyma by abnormal tissue appears to be the major pathogenetic mechanism leading to end-stage renal failure. Angiomyolipomas can be diagnosed from this characteristic sonographic pattern and the demonstration of fatty tissue in CT or MRI. Multiple renal cysts are also common in TSC. Therefore TSC should be considered in the differential diagnosis of polycystic kidney disease.

    A 12-year-old male cat was referred for progressive limb weakness lasting 2 weeks. Physical examination detected muscle atrophy and bilateral renomegaly with distortion of the renal contours. The cat was ambulatory but tetraparetic. It showed a peculiar posture on forelimbs with bilateral flexion of the carpi and extrarotation of forearms. The cat was unable to go upstairs or jump. Neurological examination showed findings compatible with peripheral nervous system involvement. Histopathological findings revealed a high grade non-B, non-T cell renal lymphoma and peripheral neuropathy characterised by demyelination, axonal degeneration and muscle denervation. In the absence of congenital, metabolic and infectious diseases or exposure to toxins, a paraneoplastic peripheral neuropathy was hypothesised. In humans and dogs, paraneoplastic peripheral neuropathies have been documented with different neoplastic processes including lymphoproliferative disorders. To the authors' knowledge, this is the first report of suspected paraneoplastic polyneuropathy in a cat with malignant tumour.

    A 64-year-old woman with metastatic clear cell renal carcinoma who had been on nivolumab immunotherapy for 10 months was referred for a FDG PET scan to monitor disease progress. New bilateral mediastinal and hilar FDG-avid lymphadenopathy was noted. Pathology on subsequent mediastinal nodal biopsy showed well-formed epithelioid granulomas with no evidence of malignancy consistent with sarcoidosis. This case illustrates that pulmonary sarcoidosis can be induced by immunotherapy in the treatment of renal cell carcinoma.

    Background Monoclonal B-cell lymphocytosis is classified as ‘high-count or clinical’ monoclonal B-cell lymphocytosis and ‘low-count or population’ monoclonal B-cell lymphocytosis. Previously, 167 first-degree relatives pertaining to sporadic (non-familial) chronic lymphocytic leukemia families were studied and the presence of seven monoclonal B-cell lymphocytosis individuals was reported. Objective The aim of this report is to describe the outcomes of five of the original monoclonal B-cell lymphocytosis individuals. Methods Flow cytometry analysis was performed on mononuclear cells previously isolated from peripheral blood samples. A strategy of sequential gating designed to identify the population of CD19+/CD5+ B-lymphocytes was used and, subsequently, the monoclonal B-cell lymphocytosis cells were characterized by the CD20weak/CD79bweak/negative phenotype. Results The monoclonal B-cell lymphocytosis clone showed consistent stability over time with little variations in size. After a median follow-up of 7.6 years, none of the five monoclonal B-cell lymphocytosis individuals progressed to chronic lymphocytic leukemia or other B-cell lymphoproliferative disease. Conclusions The data of this study suggest that chronic lymphocytic leukemia-like monoclonal B-cell lymphocytosis detected in the context of sporadic chronic lymphocytic leukemia families is not prone to clinical evolution and could be just a sign of immune senescence.

    We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK) in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 μm in the right eye and of 710 μm in the left eye, as well as an average paracentral pachymetry of 436 and 270 μm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus. PMID:20737056

    The correlation between urinary tract infection (UTI), vesicoureteric reflux (VUR) and renal scarring was studied in 89 patients (177 renal units; 1 solitary kidney) during the period 1997-2000. There were 63 males and 26 females; ages ranged from neonates to 14 years. UTI was diagnosed on the basis of a positive urine culture, VUR was diagnosed and graded by micturating cystourethrogram (MCU), and renal scarring was assessed by technetium 99 m Tc-dimercaptosuccinic acid (DMSA) scan. Ultrasonography (US) was done to evaluate renal tract dilatation and other structural abnormalities. A follow up DMSA scan was performed approximately 6 months after the initial scan. VUR was present in 106 of the 171 renal units in which it was studied and absent in 65 units. The majority of the VUR was grade V. Renal scars were seen in 90 of 177 renal units at presentation and in 72 of the 163 renal units studied at follow-up. Some information was lacking in 31 patients; hence, the correlation between UTI, VUR, and renal scarring was done in 58 patients. The majority of the suspected scars at presentation were not seen at follow-up, but most of the established scars persisted. Only 2 renal units showed scars for the first time on follow-up. On US, approximately 50% of normal kidneys showed either suspicious or established scars on DMSA scan, and patients with bilateral abnormality on US showed renal scars. Renal scars were seen in 15 of 23 children without VUR, 17 of 18 with unilateral VUR, and 16 of 17 with bilateral VUR. Thus, there is a cause-and-effect relationship between UTI and renal scarring that is made worse by VUR. DMSA scans have been shown to be the most reliable method of assessing renal scarring, and an abnormal US scan showing upper-tract dilatation or a structural abnormality may have a predictive value in the detection of renal scarring.

    Aim: Evaluation of bilateral ureteroscopic retrieval of stones as a single-stage procedure in terms of clearance of the stones, complications of the procedure and duration of hospital stay. A successful outcome was considered when both ureters were free of stones without any major complications. Materials and Methods: A total of 60 patients with bilateral ureteric stones were treated ureteroscopically from March 2006 to September 2009 in the department of Surgery (Urology unit). Majority of the patients were in their third and fourth decade of life with 38 males and 22 females. A single session bilateral ureteroscopic retrieval of stones was done using a 7.8 Fr semirigid ureteroscope. A 0.038-inch guide wire was used and advanced under direct vision, and monitored by C-arm X-ray image intensifier. Balloon dilatation of the intramural ureters was required in 82 renal units. The stones were either extracted directly or disintegrated into small pieces by lithotripsy (pneumatic) before extraction. Ureteric stenting was required in 39 patients. Patients were followed for a period of 3-12 months. Results: A total of 60 patients (120 renal units) with bilateral ureteric stones were treated ureteroscopically. The stone size in the treated patients was in the range 6-20 mm. The stones were radio-opaque in 47 patients and radiolucent in 13 patients. Single stone was present in all except two patients. Operative time ranged between 40 and 120 minutes. Stones were completely removed in 51 (85%) patients following single-session procedure of which 39 (76.4%) were stonefree intraoperatively and another 12 (23.5%) were cleared of the stones in 4 weeks follow-up. Six patients were stonefree unilaterally. Failed procedures were managed with repeated ureteroscopy, DJ stenting and ESWL or open ureterolithotomy. Intraoperatively false passage or minor ureteric perforations were seen in six patients. Postoperative complications included abdominal pain in 10, persistent fever in 4 and

    Grape seed proanthocyanindin extract (GSPE) is a polyphenolic bioflavonoid derived from grape seeds and has been widely studied for its potent antioxidant, anti-inflammatory and antitumor activities. HMGB1 is a newly discovered danger-associated molecular pattern (DAMP) that has potent proinflammatory effects once released by necrotic cells. However, the effect of GSPE on the HMGB1, and the relationship of those two with acute kidney injury and chronic kidney fibrosis are unknown. This study aimed to investigate the impact of GSPE on acute kidney injury and chronic fibrosis. C57bl/6 mice were subjected to bilateral ischemia/reperfusion (I/R) and unilateral I/R with or without GSPE administration. After bilateral I/R, mice administered GSPE had a marked improvement in renal function (BUN and Cr), decreased pathological damage and reduced inflammation. In unilateral I/R, mice subjected GSPE showed reduced tubulointerstitial fibrosis and decreased inflammatory reaction. The renoprotection of GSPE on both models was associated with the inhibition of HMGB1 nucleocytoplasmic shuttling and release, which can amplify the inflammation through binding to its downstream receptor TLR4 and facilitated P65 transcription. Thus, we have reason to believe that GSPE could be a good alternative therapy for the prevention and treatment of IR-induced renal injury and fibrosis in clinical practice. PMID:27690015

    Background: Ischemia-reperfusion (IR) injury is one of the most common causes of renal dysfunction. There is increasing evidence about the role of the reactive oxygen species (ROS) in these injuries and endogenous antioxidants seem to have an important role in decreasing the renal tissue injury. Objectives: The aim of this study was to compare the effect of recombinant human erythropoietin (EPO) and ischemic preconditioning (IPC) on renal IR injury. Materials and Methods: Twenty four male Wistar rats were allocated into four experimental groups: sham-operated, IR, EPO + IR, and IPC + IR. Rats were underwent 50 minutes bilateral ischemia followed by 24 hours reperfusion. Erythropoietin (5000 IU/kg, i.p) was administered 30 minutes before onset of ischemia. Ischemic preconditioning was performed by three cycles of 3 minutes ischemia followed by 3 minutes reperfusion. Plasma concentrations of urea and creatinine were measured. Kidney samples were taken for reactive oxidative species (ROS) measurement including superoxide dismutase (SOD) activity, glutathione (GSH) contents, and malondialdehyde (MDA) levels. Results: Compared to the sham group, IR led to renal dysfunction as evidenced by significantly higher plasma urea and creatinine. Treatment with EPO or IPC decreased urea, creatinine, and renal MDA levels and increased SOD activity and GSH contents in the kidney. Conclusions: Pretreatment with EPO and application of IPC significantly ameliorated the renal injury induced by bilateral renal IR. However, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. There were no significant differences between pretreatment with EPO or application of IPC. PMID:26866008

    A renal artery aneurysm is defined as a dilated segment of renal artery that exceeds twice the diameter of a normal renal artery. Although rare, the diagnosis and incidence of this entity have been steadily increasing due to the routine use of cross-sectional imaging. In certain cases, renal artery aneurysms may be clinically important and potentially lethal. However, knowledge of their occurrence, their natural history, and their prognosis with or without treatment is still limited. This article aims to review the recent literature concerning renal artery aneurysms, with special consideration given to physiopathology, indications for treatment, different technical options, post-procedure complications and treatment outcomes.

    The indication and timing of nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPKD) remain controversial, especially in patients who are candidates to renal transplantation (RT). The main surgical options such as unilateral vs. bilateral nephrectomy, nephrectomy before vs. after RT, or simultaneous nephrectomy and transplantation, are herein discussed. Evidence acquisition of the best surgical management available for ADPKD in the context of kidney transplantation. Systematic literature review in PubMed from 1978 to 2013 was conducted. Articles selected included:randomized controlled trials and cohort studies. Furthermore, well designed ADPKD reviews were considered for this study. Laparoscopic nephrectomy in ADPKD is a safe procedure with an acceptable complication rate. Unilateral nephrectomy has advantages over the bilateral one regarding the perioperative complication rate. Although the timing of nephrectomy is controversial, it seems that simultaneous nephrectomy and renal transplantation does not increase surgical morbidity neither affect graft survival. Simultaneous nephrectomy and RT appears to be an acceptable alternative to conventional two-stage procedure without any increased morbidity, in the context of ADPKD. Furthermore, laparoscopic nephrectomy performed in experienced centres is a safe alternative to conventional approach. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    Bilateral non traumatic femoral neck fatigue fracture is a rare condition usually occurring secondary to medical conditions such as pregnancy, pelvic irradiation, corticosteroid exposure, chronic renal failure and osteomalacia. In this report, we present three young female patients with bilateral femoral neck fracture secondary to osteomalacia. The underlying cause of osteomalacia was Celiac disease in all patients. The patients were treated with closed reduction and internal fixation with cannulated lag screws. They were free of pain and full weight bearing was achieved at three months. There were no complications, avascular necrosis and nonunion during the follow up period. In patients with bone pain, non traumatic fractures and muscle weakness, osteomalacia should be kept in mind and proper diagnostic work-up should be performed to identify the underlying cause of osteomalacia such as celiac disease.

    Granulomatosis with polyangiitis (GPA) formerly called Wegener’s granulomatosis is a chronic necrotizing granulomatous inflammatory disease with systemic vasculitis involving the upper and lower respiratory tract, and kidneys. The typical histopathology is that of necrotizing granulomatous inflammation with palisading histiocytes, neutrophils, and lymphocytes. We report a case of a 57-year-old lady presenting with left eye swelling, left ear pain and discharge, but with no pulmonary or renal symptoms. Investigations revealed positive cytoplasmic antineutrophil cytoplasmic antibodies and proteinase 3 antibodies. The CT and MRI showed meningeal thickening and bilateral structural changes of the orbits and mastoids. Lacrimal gland biopsy showed non necrotizing granulation with an eosinophilic infiltration. She was diagnosed with eosinophilic variant of GPA of the eyes and mastoid bones bilaterally extending to dura and sparing the lungs and kidneys. She responded to corticosteroids and rituximab.

    Amyotrophic neuralgia is an uncommon neuropathy characterized by severe unilateral shoulder pain. Isolated or concomitant involvement of other peripheral motor nerves depending on the brachial plexus such as phrenic or laryngeal nerves is unusual(1). Its etiology is unknown, yet several explanatory factors have been proposed. Phrenic nerve involvement, either unilateral or bilateral, is exceedingly rare. Diagnosis relies on anamnesis, functional and imaging investigations and electromyogram. We report the case of a 48-year-old woman with a past history of renal transplantation due to proliferative glomerulonephritis with subsequent transplant rejection, who was eventually diagnosed with amyotrophic neuralgia with bilateral phrenic involvement, and who required sustained non-invasive mechanical ventilation.

    From 1977 to 1987, 30 women were treated with definitive irradiation following breast-conserving surgery for bilateral carcinoma of the breast for a total of 60 treated breasts. Eleven women presented with concurrent bilateral carcinoma, and 19 women had sequential bilateral carcinoma. Pathologic axillary staging was performed in 51 of the 60 treated breasts. A total dose of greater than or equal to 6,000 cGy was delivered from breast tangential irradiation plus an electron or Iridium boost to 95% (57/60) of the treated breasts. A third field was used to treat the regional axillary and supraclavicular lymph nodes bilaterally in three women (10%) and unilaterally in ten women (33%). Tangential fields were matched at midline in 17 patients, and in ten patients, the tangential fields overlapped by up to 3 cm on skin. In two patients, the tangential fields were matched to an internal mammary nodal field, and in one patient, tangential fields were matched to a mediastinal field given for postoperative radiotherapy for lung cancer. For the overall group of 30 patients, the 5-year actuarial NED survival following treatment of the first breast cancer was 79%, and the 5-year actuarial relapse-free survival was 72%. For the 60 treated breasts, the 5-year actuarial local failure rate was 6%. An analysis of complications and cosmesis showed results similar to previously reported results for unilateral breast cancer. These results show that definitive irradiation following breast-conserving surgery for patients with bilateral breast cancer can technically be delivered with low complication rates and with acceptable survival and local control rates. Definitive irradiation should be considered as an acceptable alternative treatment to bilateral mastectomy for appropriately selected patients with concurrent or sequential bilateral early stage carcinoma of the breast.

    The mechanism of a rise in blood pressure after kidney irradiation is unclear but most likely of renal origin. We have investigated the role of the renin-angiotensin system and dietary salt restriction in the development of systolic hypertension after bilateral kidney irradiation in young and adult rats. Three to 12 months after a single X-ray dose of 7.5 or 12.5 Gy to both kidneys of young and adult rats, the systolic blood pressure (SBP) and plasma renin concentration (PRC) were measured regularly. A single X-ray dose of 12.5 Gy caused a moderate rise in SBP and a slight reduction in PRC in both young and adult rats. A dose of 7.5 Gy did not significantly alter the SBP or PRC during the follow-up period of 1 year. In a second experiment, the kidneys of young rats received an X-ray dose of 20 Gy. Subsequently, rats were kept on a standard diet (110 mmol sodium/kg) or a sodium-poor diet (10 mmol sodium/kg). On both diets, SBP started to rise rapidly 3 months after kidney irradiation. Sodium balance studies carried out at that time revealed an increased sodium retention in the irradiated rats compared to controls on the same diet. In rats on a low sodium intake, there was neither a delay nor an alleviation in the development of hypertension. Compared to controls, the PRC tended to be lower in irradiated rats up to 4 months after irradiation. Subsequently, malignant hypertension developed in all 20 Gy rats, resulting in pressure natriuresis, stimulating the renin-angiotensin system. Our findings indicated that hypertension after bilateral kidney irradiation was not primarily the result of an activation of the renin-angiotensin system. Although there were some indications that sodium retention played a role, dietary sodium restriction did not influence the development of hypertension.

    Bilateral agenesis of the anterior cruciate ligament (ACL) is extremely rare. We describe a 13-year-old girl who presented with bilateral knee pain without history of trauma; she has two family members with knee instability. Magnetic resonance imaging showed bilateral absence of the ACL, and medial posterior horn meniscal tears. Bilateral arthroscopic partial meniscectomy and anterior cruciate ligament reconstruction was performed.

    We report herein a 27-year-old male case of inherited distal renal tubular acidosis complicated with renal diabetes insipidus, the symptoms of which were aggravated by the occurrence of diabetes mellitus. At 2 months after birth, he was diagnosed as having inherited distal renal tubular acidosis and thereafter supplementation of both potassium and alkali was started to treat his hypokalemia and metabolic acidosis. At the age of 4 years, calcification of the bilateral renal medulla was detected by computed tomography. Subsequently his urinary volume gradually increased and polyuria of approximately 4 L/day persisted. At the age of 27 years, he became fond of sugar-sweetened drinks and also often forgot to take the medicine. He was admitted to our hospital due to polyuria of more than 10 L day, muscle weakness and gait disturbance. Laboratory tests disclosed worsening of both hypokalemia and metabolic acidosis in addition to severe hyperglycemia. It seemed likely that occurrence of diabetes mellitus and cessation of medications can induce osmotic diuresis and aggravate hypokalemia and metabolic acidosis. Consequently, severe dehydration, hypokalemia-induced damage of his urinary concentration ability and enhancement of the renin angiotensin system occurred and thereby possibly worsened his hypokalemia and metabolic acidosis. As normalization of hyperglycemia and metabolic acidosis might have exacerbated hypokalemia further, dehydration and hypokalemia were treated first. Following intensive treatment, these abnormalities were improved, but polyuria persisted. Elevated plasma antidiuretic hormone (12.0 pg/mL) and deficit of renal responses to antidiuretic hormone suggested that the polyuria was attributable to the preexisting renal diabetes insipidus possibly caused by bilateral renal medulla calcification. Thiazide diuretic or nonsteroidal anti-inflammatory drugs were not effective for the treatment of diabetes insipidus in the present case.

    To evaluate the speed and precision of split renal volume (SRV) measurement, which is the ratio of unilateral renal volume to bilateral renal volume, using a newly developed software for computed tomographic (CT) volumetry and to investigate the usefulness of SRV for the estimation of split renal function (SRF) in kidney donors. Both dynamic CT and renal scintigraphy in 28 adult potential living renal donors were the subjects of this study. We calculated SRV using the newly developed volumetric software built into a PACS viewer (n-SRV), and compared it with SRV calculated using a conventional workstation, ZIOSOFT (z-SRV). The correlation with split renal function (SRF) using (99m)Tc-DMSA scintigraphy was also investigated. The time required for volumetry of bilateral kidneys with the newly developed software (16.7±3.9s) was significantly shorter than that of the workstation (102.6±38.9s, p<0.0001). The results of n-SRV (49.7±4.0%) were highly consistent with those of z-SRV (49.9±3.6%), with a mean discrepancy of 0.12±0.84%. The SRF also agreed well with the n-SRV, with a mean discrepancy of 0.25±1.65%. The dominant side determined by SRF and n-SRV showed agreement in 26 of 28 cases (92.9%). The newly developed software for CT volumetry was more rapid than the conventional workstation volumetry and just as accurate, and was suggested to be useful for the estimation of SRF and thus the dominant side in kidney donors.

    A 37-year-old nulligravid woman presented with a 2-year history of uterine prolapse along with mixed incontinence. Gynecological examination confirmed third degree cystocele and uterine prolapse. Renal ultrasonography showed enlarged kidneys and marked dilation of the bilateral pelvicalyceal system. She was hospitalized and a ring pessary was inserted after bladder catheterization. Her preoperative evaluation was performed and the patient was operated one month after her first admission. Anterior colporrhaphy along with Kurt Extraperitoneal Ligamentopexy was performed without any complication. A control visit on second postoperative month revealed recovery of incontinence symptoms and no prolapse was observed. To our knowledge this is the first reported treatment of a case with bilateral hydronephrosis due to uterine prolapse that were corrected and overcame with a novel minimally invasive extraperitoneal approach by fixation of bilateral round ligaments to the rectus fascia sheet.

    Calcium channel blockers are commonly prescribed medications; calcium channel blocker overdose is becoming increasingly prevalent. The typical presentation of a calcium channel blocker overdose is hypotension and decreased level of consciousness. We describe a case of a calcium channel blocker overdose that led to bilateral cortical blindness, a presentation that has not previously been reported. A 49-year-old white woman with known bilateral early optic atrophy presented to our hospital with hypotension and obtundation following a known ingestion of 150 mg of amlodipine. She was transferred to our intensive care unit where she was intubated, mechanically ventilated, and required maximal vasopressor support (norepinephrine 40 mcg/minute, epinephrine 40 mcg/minute, and vasopressin 2.4 units/hour) along with intravenously administered crystalloid boluses. Despite these measures, she continued to deteriorate with persistent hypotension and tachycardia, as well as anuria. Intralipid emulsion therapy was subsequently administered to which no initial response was observed. A chest X-ray revealed diffuse pulmonary edema; intravenous diuresis as well as continuous renal replacement therapy was initiated. Following the initiation of continuous renal replacement therapy, her oxygen requirements as well as urine output began to improve, and 3 days later she was liberated from mechanical ventilation. Following extubation, she complained of new onset visual impairment, specifically seeing only red-green colors, but no objects. An ophthalmologic examination revealed that this was due to bilateral optic atrophy from prolonged hypotension during the first 24 hours after the overdose. Persistent hypotension in the setting of a calcium channel blocker overdose can lead to worsening optic atrophy resulting in bilateral cortical blindness.

    The inferior vena cava (IVC) is the most common site of leiomyosarcomas arising from a vascular origin. Leiomyosarcomas of the IVC are categorized by anatomical location. Zone I refers to the infrarenal portion of the IVC, Zone II from the hepatic veins to the renal veins, and Zone III from the right atrium to the hepatic veins. This is a rare presentation of a Zone I-III leiomyosarcoma. Fifty-two-years-old female with a medical history significant only for HTN was admitted to the hospital with bilateral lower extremity edema and dyspnea. Two-dimensional echo demonstrated a right atrial thrombus, extending into the IVC. On subsequent CT and MRI, a 15 cm mass was noted that began in the right atrium and extended into the IVC, with continuation below the renal veins to above the level of the confluence of the common iliac veins. The patient underwent a complete resection of the mass, replacement of the IVC with Dacron graft, total hepatectomy and bilateral nephrectomy, with liver and kidney autotransplantation. Pathology was consistent with a high grade spindle cell sarcoma of vena cava origin. Patient was readmitted approximately 4 weeks postoperatively to begin adjuvant chemotherapy. This case represents a zone I-III IVC leiomyosarcoma treated with surgical R0 resection. This included a hepatectomy, bilateral nephrectomy, and hepatic and left renal autotransplantation. These complex tumors should be treated with surgical resection, and require a multidisciplinary approach.

    To assess bilateral breast cancer patients, initially diagnosed with stage II unilateral breast cancer. 113 patients with stage 0-II breast cancer diagnosed between 1983 and 2011 were assessed. Of these, 8 patients had bilateral breast cancer: 7 patients with metachronous bilateral breast cancer and 1 patient with synchronous breast cancer. Breast ultrasound, mammography, computed tomography and magnetic resonance imaging were used to diagnose recurrence, loco regional and distant metastasis. Age at diagnosis ranged from 37 to 59 years, with a maximum age incidence in the 4th decade (age between: 31-40 years). The average time interval between the two breast cancers was 8.125 years. The most common histological type was invasive ductal carcinoma. All eight patients with bilateral breast cancer had at least one type of recurrence/metastasis, mostly in the liver, and statistically the pleuropulmonary and liver metastases were the most frequent causes of death. Patients in the 4th decade diagnosed with unilateral breast cancer are at risk of developing bilateral breast cancer. In metachronous breast cancer, the time interval between the detection of the second breast cancer and death is directly proportional to the time interval between the two breast cancers.

    Rates of bilateral mastectomy as treatment for unilateral breast cancer have been rising. Quantitative analyses have resulted in assumptions about why women choose this procedure, without confirmation from the women. The objective of this study was to explore a woman's decision making in the choice of bilateral mastectomy as a treatment for unilateral breast cancer, regardless of stage. A qualitative descriptive design was used. In-depth interviews were conducted by 2 researchers using a semistructured interview guide to elicit data, which were coded and analyzed using thematic analysis. Twenty-three women were interviewed. Five themes were identified that address specific determinants of the decision-making process: finding something, collecting evidence, perceived level of risk, identifying priorities, and making the decision. Nine women reported that their physicians recommended bilateral mastectomy. Women who recalled being advised of their risk of recurrence reported overestimates of that risk. The reasons women chose bilateral mastectomy were to avoid a lifetime of follow-up screenings with the subsequent fear of hearing that the breast cancer had returned and wanting to stay alive and well for their children and families. Except for women carrying genetic susceptibility to breast cancer, bilateral mastectomy is not considered the standard of care. Yet women are being offered or choosing this procedure. Nurses can be advocates for women by speaking positively about how women have the right to choose their treatment based on best evidence and personal choice. This evidence should include benefits and risks of the treatment.

  10. The Renal Functional Defect of Postobstructive Nephropathy

    1972-01-01

    This study was designed to examine the pathogenesis of the excretory defect produced by bilateral ureteral obstruction in the rat. After release of obstruction of 24 hr duration glomerular filtration rate was reduced to 20% of normal. Free flow proximal tubular pressure was normal, excluding residual obstruction as a cause of depressed filtration, and indicating that an intrarenal hemodynamic abnormality was primarily responsible for the excretory defect. Total renal blood flow and cortical distribution of flow were normal. Clearance and micropuncture studies indicated the presence of marked heterogeneity of nephron function with residual excretory function residing primarily in vasodilated nephrons in which decreased postglomerular arteriolar resistance effected a reduction in glomerular filtration pressure. Heterogeneity of nephron function was evidenced by a wide scatter of values for single nephron filtration rate and from direct intratubular injection of dye which revealed that at least 28% of surface nephrons were either nonfiltering or had filtration rates too low to measure. The observed decrease in Hippuran extraction and increased ratio of Hippuran to inulin clearance ratio is characteristic of the vasodilated kidney. Further evidence of the vasodilated nature of residual functioning nephrons was demonstrated by the failure of intrarenal papaverine infusion to increase filtration rate in this lesion. The hemodynamic defect produced by bilateral obstruction is contrasted with that seen after release of unilateral ureteral ligation in which depression of filtration rate appears to result primarily from preglomerular vasoconstriction. This difference raises the possibility that a vasodilating substance accumulates during total suppression of renal excretory function. Diuresis and natriuresis were constant features of the postobstructive lesion. The present data support previously published studies which localize the defect in sodium transport to the distal

    Autosomal dominant polycystic kidney disease (ADPKD) is a genetic systemic disorder, which is associated with cyst formation in several organs, renal function decline and a higher prevalence of intracranial aneurysms. We report a 52-year-old, otherwise healthy, man with ADPKD who had asymptomatic, bilateral, multiple cysts in the choroid plexus, which is an extremely rare abnormality. Recent evidence suggests that the polycystin proteins, which are dysfunctional in ADPKD, are found in ciliated choroid plexus cells that are involved with regulation of cerebrospinal fluid homeostasis. We hypothesize therefore that choroid plexus cysts may be part of the ADPKD phenotype, which has not been described before.

    Granulomatosis with polyangiitisis [(GPA) or Wegener granulomatosis] is a multi-system disease characterized by granuloma formation and necrotizing vasculitis. GPA classically shows involvement of the respiratory tracts and the renal system. However, locoregional disease is common and may include otologic manifestations. Although otologic involvement can occur during the course of GPA, no report has described facial palsy with sudden sensorineural total deafness with vertigo as the presenting feature of GPA. This case describes a patient with multiorgan involving resistant form of GPA initially presenting with bilateral profound sudden sensorineural hearing loss and left facial paralysis with vertigo. The condition responded well to treatment with rituximab.

    2009-09-01

    Renal replacement therapy became a common clinical tool to treat patients with severe acute kidney injury (AKI) since the 1960s. During this time dialytic options have expanded considerably; biocompatible membranes, bicarbonate dialysate and dialysis machines with volumetric ultrafiltration control have improved the treatment for acute kidney injury. Along with advances in methods of intermittent hemodialysis, continuous renal replacement therapies have gained widespread acceptance in the treatment of dialysis-requiring AKI. However, many of the fundamental aspects of the renal replacement treatment such as indication, timing of dialytic intervention, and choice of dialysis modality are still controversial and may influence AKI patient's outcomes. This review outlines current concepts in the use of dialysis techniques for AKI and suggests an approach for selecting the optimal method of renal replacement therapy.

    PubMed Central

    Davies, E. Rhys

    1970-01-01

    Renal scintiscanning is a simple investigation that does not require special preparation and is well tolerated by patients. Radiopharmaceuticals used in linear scanning are accumulated in the renal cortex. This accumulation is diminished: (a) when the cortex is destroyed, e.g. by pyelonephritis, injury, etc.; and (b) when the amount available to the cortex is reduced, e.g. by ischaemia. The scintigram depicts the kidneys unimpeded by bowel contents, gives a qualitative assessment of renal function and shows the distribution of zones of normal function. Recent technical improvements show great promise in deriving a quantitative measure of renal function in some circumstances. The location of normally functioning cortex is often important in the management of renal diseases and the value of scintiscanning is then considerable. It is occasionally useful in planning surgery. The anatomy of the renal collecting system can be shown only by urography. High dose techniques achieve this even in the face of renal failure, and scintiscanning has few indications in investigating lesions that distort the renal anatomy, e.g. tumours and cysts. Renal scintiscanning is a very valuable additional method to urography, arteriography and renography in investigation of renal disorders.

    Primary renal leiomyosarcomas are rare, aggressive tumors. They constitute 1–2% of adult malignant renal tumors. Although leiomyosarcomas are the most common histological type (50–60%) of renal sarcomas, information on renal leiomyosarcoma is limited. Local or systemic recurrences are common. The radiological appearance of renal leiomyosarcomas is not specific, therefore renal leiomyosarcoma cannot be distinguished from renal cell carcinoma by imaging methods in all patients. A 74-year-old female patient presented to our clinic complaining of a palpable mass on the right side of her abdomen in November 2012. The abdominal magnetic resonance imaging revealed a mass, 25 × 24 × 23 cm in size. Her past medical history revealed that she has undergone right radical nephrectomy in 2007, due to a 11 × 12 × 13 cm renal mass that was then reported as renal cell carcinoma on abdominal magnetic resonance imaging, but the pathological diagnosis was low-grade renal leiomyosarcoma. The most recent follow-up of the patient was in 2011, with no signs of local recurrence or distant metastases within this four-year period. The patient underwent laparotomy on November 2012, and a 35 cm retroperitoneal mass was excised. The pathological examination of the mass was reported as high-grade leiomyosarcoma. The formation of this giant retroperitoneal mass in 1 year can be explained by the transformation of the lesion’s pathology from low-grade to a high-grade tumor. PMID:27436926

    An extensive iatrogenic aortic type B dissection during percutaneous transluminal renal angioplasty (PTRA) for bilateral renal artery stenosis was treated with a covered stent placed in the right renal artery. Control angiography confirmed closure of the entry. Postprocedural CT demonstrated a thick intramural hematoma (IMH) up to the left subclavian artery. CT follow-up at 8 months showed an almost complete resorption of the IMH. While medical treatment is the standard therapy for type B dissections, closure of the intimal tear with a covered stent may be an additional option in extensive cases during PTRA.

    This retrospective study compared complication rates in 93 client-owned dogs (119 stifles) undergoing single-session bilateral, staged bilateral, or unilateral surgery for bilateral medial patellar luxation. Clinical characteristics and complication rates were compared and risk factors for major complications were explored. Sixty-five dogs had unilateral, 16 staged bilateral and 11 single-session bilateral surgery. Complications occurred in 28/119 stifles (24%), 11 (9%) of which required revision surgery. Patellar reluxation occurred in 7/119 (6%) stifles, with no revision required. There was no significant association between timing of surgery and incidence of complications. In dogs < 10 kg with bilateral medial patellar luxation, single-session bilateral surgery is a feasible treatment option with a complication rate comparable to staged bilateral or unilateral medial patellar luxation surgery.

    Two hundred and forty four patients underwent either simultaneous bilateral inguinal hernia repair (n = 122) or unilateral inguinal hernia (n = 122) repair at a general hospital between January 1971 and December 1981. The two groups of patients were matched for age and sex. Both groups had a similar overall incidence of post-operative complications and in both groups the duration of post-operative stay and duration of operating time were similar. Chest infections developed in 12 patients after bilateral repair and in 3 patients after unilateral repair (P less than 0.02). All patients were assessed prospectively from 4 to 15 years after operation, when no significant difference in the number of recurrent hernias was found. Our results suggest that simultaneous bilateral inguinal herniorrhaphy is economical in terms of both operating time and duration of hospital stay, and that this economy is not bought at a cost of increased short term morbidity or long-term recurrence rate.

    Purpose To report a bilateral leukocoria case in a patient suffering from afibrinogenemia. Methods An observational case where congenital afibrinogenemia was presented with bilateral retinal and vitreous hemorrhages that proceeded to vitreoretinal surgery was presented. In addition, complete ophthalmic and radiological examinations and vitreoretinal surgery were performed. Results Right eye had a complete recovery while the left eye showed serious proliferative vitreoretinopathy and shortened retina. Three years after the surgery clinical examination showed that the right eye was aphacic with an attached retina and clear ocular media while the left eye was phtysic. Conclusion We recommend broad clotting profile for infants suffering from vitreous or retinal hemorrhages with no obvious physical abuse. Our present case furthermore implies that afibrinogenemia can lie beneath the pathogenesis of bilateral leukocoria and should alert physician for the presence of an afibrinogenemia among several types of bleeding predispositions.

    In animal models, kidney formation is known to be controlled by the proteins RET, GDNF, and GFRA1; however, no human studies to date have shown an association between abnormal kidney development and mutation of these genes. We hypothesized that stillborn fetuses with congenital renal agenesis or severe dysplasia would possess mutations in RET, GDNF, or GFRA1. We assayed for mutations in these genes in 33 stillborn fetuses that had bilateral or unilateral renal agenesis (29 subjects) or severe congenital renal dysplasia (4 subjects). Mutations in RET were found in 7 of 19 fetuses with bilateral renal agenesis (37%) and 2 of 10 fetuses (20%) with unilateral agenesis. In two fetuses, there were two different RET mutations found, and a total of ten different sequence variations were identified. We also investigated whether these mutations affected RET activation; in each case, RET phosphorylation was either absent or constitutively activated. A GNDF mutation was identified in only one fetus with unilateral agenesis; this subject also had two RET mutations. No GFRA1 mutations were seen in any fetuses. These data suggest that in humans, mutations in RET and GDNF may contribute significantly to abnormal kidney development. PMID:18252215

    Bilateral prophylactic mastectomy in women with increased breast cancer risk dramatically reduces breast cancer occurrence but little is known about psychosocial outcomes. To examine long-term quality of life after bilateral prophylactic mastectomy, we mailed surveys to 195 women who had the procedure from 1979 to 1999 and to a random sample of 117 women at increased breast cancer risk who did not have the procedure. Measures were modeled on or drawn directly from validated instruments designed to assess quality of life, body image, sexuality, breast cancer concerns, depression, health perception, and demographic characteristics. We used logistic regression to examine associations between quality of life and other domains. The response rate was 58%, with 106 women with and 62 women without prophylactic mastectomy returning complete surveys. Among women who underwent bilateral prophylactic mastectomy, 84% were satisfied with their decision to have the procedure; 61% reported high contentment with quality of life compared with an identical 61% of women who did not have the procedure (P = 1.0). Among all subjects, diminished contentment with quality of life was not associated with bilateral prophylactic mastectomy but with dissatisfaction with sex life (adjusted ratio [OR] = 2.5, 95% confidence interval [CI] = 1.0-6.2), possible depression (CES-D > 16, OR = 4.9, CI = 2.0-11.8), and poor or fair general health perception (OR = 8.3, 95% CI = 2.4-29.0). The majority of women reported satisfaction with bilateral prophylactic mastectomy and experienced psychosocial outcomes similar to women with similarly elevated breast cancer risk who did not undergo prophylactic mastectomy. Bilateral prophylactic mastectomy appears to neither positively nor negatively impact long-term psychosocial outcomes.

    Papillary thyroid cancer is the most common type of thyroid malignancy and has an excellent prognosis. Distant organ metastasis is rare. Bilateral adrenal metastases with iodine uptake has not been described before. A 47-year-old woman presented for evaluation because of severe right upper arm pain and weakness. Magnetic resonance imaging of the thoracic spine showed a compression fracture at the third thoracic vertebra associated with a soft tissue mass. Computed tomography (CT)-guided biopsy of the mass showed metastatic papillary thyroid carcinoma. Ultrasonography of the neck showed an enlarged right thyroid lobe with cervical lymphadenopathy. A high-resolution CT scan of the chest showed multiple bilateral pulmonary nodules. Treatment included total thyroidectomy and lymph node dissection, external beam radiation to the thoracic spine, and (131)I therapy. Initial whole body (131)I scintigraphy showed faint uptake in the right upper abdomen, interpreted as a sign of physiologic bowel activity; however, repeat whole body (131)I scintigraphy showed increased uptake in both adrenal glands, consistent with metastatic disease. Serial abdominal CT scans showed progressively enlarging bilateral adrenal masses. Despite additional treatment with (131)I, the patient's disease progressed at all metastatic sites. This patient had bilateral adrenal metastases from advanced papillary thyroid cancer with distant metastasis to lung and bone at initial presentation and poor response to repeated (131)I therapy. Unilateral adrenal metastasis from thyroid cancer has been described previously in six cases; this is the first case report of bilateral adrenal metastases. Bilateral adrenal metastasis is rare in papillary thyroid cancer. Elevated abdominal uptake of (131)I in a high-risk patient may be a sign of abdominal metastatic disease.

    Renal artery embolization (RAE) is an effective minimally invasive alternative procedure for the treatment of a variety of conditions. Since the 1970s when RAE was first developed, technical advances and growing experience have expanded the indications to not only include treatment of conditions such as symptomatic hematuria and palliation for metastatic renal cancer, but also preoperative infarction of renal tumors, treatment of angiomyolipomas, vascular malformations, medical renal disease, and complications following renal transplantation. With the drastically improved morbidity associated with this technique in part due to the introduction of more precise embolic agents and smaller delivery catheters, RAE continues to gain popularity for various urologic conditions. The indications and techniques for renal artery embolization are reviewed in the following sections. PMID:23204638

    Purpose Outcome assessment after double level tibial lengthening in patients with dwarfism. Methods Fourteen patients with dwarfism were analyzed after bilateral simultaneous double level tibial lengthening. Results Average age was 15.1 years. Average lengthening was 13.5 cm. The two levels were lengthened by an average of 7.5 cm proximally and 6.0 cm distally. Concomitant deformities were also addressed during lengthening. External fixation treatment time averaged 8.8 months. Healing index averaged 0.7 months/cm. Conclusion Bilateral tibial lengthening for dwarfism is difficult, but the results are usually quite gratifying. PMID:26566326

    A 28-year-old man presented with bilateral acute loss of vision following a high-voltage injury. The visual acuity was 6/36 in the right eye and 6/24 in the left eye. Fundus examination revealed a well-defined round lesion simulating a full thickness macular hole in the right eye and yellow deposits in the macular area in the left eye. Optical coherence tomography (OCT) showed bilateral macular cysts, with intact outer and inner retinal layers. At 1 month follow up, OCT showed a persistent macular cyst in the right eye with spontaneous resolution of the macular cyst along with visual improvement in the left eye.

    Bilateral involvement of the breast with tuberculosis is extremely rare. It most commonly affects young lactating multiparous females, although rarely it may be reported in prepubescent males also. We present a case of a 27-year-old nulliparous female who presented with a history of multiple pus discharging sinuses around both areolae and was diagnosed as a case of bilateral tubercular mastitis. Tubercular mastitis being a paucibacillary disease, diagnosis is often difficult. Treatment consists of antitubercular therapy with or without surgery.​.

    Primary solitary amyloidoma of Meckel's cave is rare, and a bilateral location is even more rare. To the best of our knowledge, only 12 cases in the literature have described such a primary lesion, including one case of bilateral involvement of Meckel's cave. We report here on the case of a 57-year-old woman presenting with pseudotumor masses involving both Meckel's caves and responsible for trigeminal neuropathy. The final diagnosis of amyloidoma was made on the basis of histological examination of surgical biopsy specimens.

    Extradural hematoma (EDH) occurs in approximately 2% of all patients with head injuries. Bilateral EDHs account for 2–10% of all acute EDHs in adults but are exceedingly rare in children. Posterior fossa EDHs occurs in 5% of all cases of EDHs. EDHs in children are more frequently venous (from tears of a dural sinus or diploic veins) and consequently have a better prognosis than EDHs in adults. Once the diagnosis of BEH is confirmed, urgent surgical treatment should be considered. We are reporting such rare form of injury as bilateral occipital EDH with supratentorial extension in 12 years child following road traffic accident. PMID:26557174

    A 19-year-old Indian man presented with a history of proximal muscle weakness, knock knees and gynaecomastia. On examination he had features of rickets and bilateral small testes. Karyotyping revealed a chromosomal pattern of 47,XXX, confirming the diagnosis of Klinefelter's syndrome. He was also found to have hyperchloraemic metabolic acidosis with hypokalaemia, hypophosphataemia, phosphaturia and glycosuria, which favoured a diagnosis of proximal renal tubular acidosis. Patients with Klinefelter's syndrome typically have a tall stature due to androgen deficiency, resulting in unfused epiphyses and an additional X chromosome. However, this patient had a short stature due to associated proximal renal tubular acidosis. To the best of our knowledge, this is the second case of Klinefelter's syndrome with short stature due to associated renal tubular acidosis reported in the literature. This report highlights the need to consider other causes when patients with Klinefelter's syndrome present with a short stature.

    Background: Renal sympathetic nerves are involved in the reflective activation of the sympathetic nervous system in circulatory control. Catheter-based renal denervation (RDN) ameliorated treatment-resistant hypertension safely, but 10%–20% of treated patients are nonresponders to radiofrequency denervation. The purpose of this study was to investigate the safety and efficiency of cryoablation for sympathetic denervation in a swine model and to explore a new way of RDN. Methods: Seven swines randomly assigned to two groups: Renal cryoablation (CR) group and control group. The control group underwent renal angiogram only. The CR group underwent renal angiogram plus bilateral renal cryoablation. Renal angiograms via femoral were performed before denervation, after denervation and prior to the sacrifice to access the diameter of renal arterial and the pressure of aorta abdominalis. Euthanasia of the swine was performed on 28-day to access norepinephrine (NE) changes of the renal cortex and the changes of renal nerves. Results: Cryoablation did not induce severe complications at any time point. There was no significant change in diameter of renal artery. CR reduced systolic blood pressure (BP) from 145.50 ± 9.95 mmHg at baseline to 119.00 ± 14.09 mmHg. There was a slight but insignificant decrease in diastolic BP. The main nerve changes at 28-day consisted of necrosis with perineurial fibrosis at the site of CR exposure in conjunction with the nerve vacuolation. Compared with the control group, renal tissue NE of CR group decreased by 89.85%. Conclusions: Percutaneous catheter-based cryoablation of the renal artery is safe. CR could effectively reduce NE storing in the renal cortex, and the efficiency could be maintained 28-day at least. PMID:25758274

    To compare speech understanding with bimodal hearing and bilateral cochlear implants (CIs). Within-subjects, repeated-measures. Speech understanding was assessed in the following conditions: unilateral hearing aid (HA) in the non-implanted ear, unilateral CI, bimodal (CI + HA), and bilateral CI. In addition, three participants had bilateral hearing preservation and were also tested with bilateral CIs and bilateral HAs (BiBi). Tertiary academic CI center. Eight adult sequential bilateral recipients who, despite achieving incredibly high performance with the first CI, self-selected for bilateral cochlear implantation. Bilateral cochlear implantation. Speech understanding for the adult minimum speech test battery as well as sentences in semidiffuse noise using the R-SPACE system. Bilateral CIs afforded significant individual improvement in a complex listening environment even for individuals demonstrating near perfect sentence scores with both the first CI alone as well as the bimodal condition. The 3 BiBi participants demonstrated additional significant benefit over the bilateral CI condition-presumably because of the availability of interaural time difference cues. These data suggest that, for noisy environments, adding a second implant can significantly improve speech understanding-even for high-performing unilateral CI with bimodal hearing. In diffuse noise conditions, bilateral acoustic hearing can yield even greater benefits beyond that offered by bilateral implantation.

    Chromophobe cell renal carcinoma is a recently established subtype of renal cell carcinoma. Herein we report a case of chromophobe cell renal carcinoma in a 67-year-old male patient who occasionally underwent computed tomography. In a microscopic study with hematoxylin and eosin stain, clear eosinophilic cytoplasm, and a moderately atypical nucleus were observed. And it was stained positively by Hale's colloidal iron. Ultrastructurally, the cytoplasm was filled with numerous microvesicles. From these results, this tumor was pathologically diagnosed as chromophobe cell renal carcinoma.

We report a patient with bilateral psoas abscesses causing extensive pulmonary emboli through compression of the iliac vein. Case Report: A 47-year-old man presented with bilateral leg swelling over 4 weeks. Physical examination revealed a thin male with bilateral leg swelling, extending to the thigh on his left side. He had hemoglobin of 10.5 g/dl, leukocytosis of 16 000/ml, and an elevated D-dimer. A computed tomography (CT) angiogram of his chest showed extensive bilateral pulmonary emboli and infarcts. He remained febrile with vague flank pain, prompting a CT of his abdomen and pelvis that showed large, multiloculated, septated, bilateral psoas abscesses with compression of the left femoral vein by the left psoas abscess and a thrombus distal to the occlusion. Two liters of pus was drained from the left psoas abscess by CT-guidance, and although the Gram staining showed Gram-positive cocci in clusters, cultures from the abscess and blood were negative. A repeat CT showed resolution of the abscesses, and the drain was removed. He was discharged to a nursing home to complete a course of intravenous antibiotics and anticoagulation. Conclusions: Although the infectious complications of psoas abscesses have been described in the literature, the mechanical complications of bilateral psoas abscesses are lacking. It is important to assess for complete resolution of psoas abscesses through

    Zhu, Yi; Wang, Youping; Wang, Donna H

    2005-10-01

    To test the hypothesis that activation of the vanilloid receptor 1 (VR1) expressed in sensory nerves innervating the renal pelvis leads to diuresis and natriuresis, a selective VR1 receptor agonist, capsaicin (2.4 nmol), or vehicle was perfused intravenously or into the left renal pelvis of anesthetized rats at a rate without changing renal perfusion pressure. Mean arterial pressure was not altered by capsaicin administered intravenously or into the renal pelvis. Capsaicin perfusion into the left renal pelvis but not intravenously caused significant increases in urine flow rate and urinary sodium excretion bilaterally in a dose-dependent manner, which were abolished by capsazepine, a selective VR1 receptor antagonist, given ipsilaterally to the renal pelvis or by ipsilateral renal denervation. Capsaicin given intravenously or into the left renal pelvis increased plasma calcitonin gene-related peptide levels to the same extent. Increased plasma calcitonin gene-related peptide levels induced by capsaicin (68.9+/-2.8 pg/mL) perfusion into the renal pelvis was prevented either by capsazepine (22.5+/-10.1 pg/mL) given ipsilaterally into the renal pelvis or by ipsilateral renal denervation (25.9+/-2.3 pg/mL). Taken together, our data show that unilateral activation of VR1-positive sensory nerves innervating the renal pelvis leads to bilateral diuresis and natriuresis via a mechanism that is independent of plasma calcitonin gene-related peptide levels. These data suggest that VR1-positive sensory nerves in the kidney enhance renal excretory function, a mechanism that may be critically involved in sodium and fluid homeostasis.

    Renal Osteodystrophy (ROD) is a common complication of chronic renal disease (CRD) and is the part of a broad spectrum of disorders of mineral metabolism that occurs in the clinical setting. It occurs early in the course of chronic renal failure and progresses as the kidney function deteriorates. It is an osseous alteration believed to arise from increased parathyroid function associated with inappropriate calcium, phosphorus and vitamin D metabolism. Involvement of the jaws is common and radiographic alterations are often one of the earliest signs of chronic renal failure. Herein, reporting a case of Chronic Renal Failure (Bilateral Grade I Neuropathy) with ROD presenting oral manifestations in an 11-year -old male child. PMID:25302278

    Wegener's granulomatosis (WG) is a necrotizing granulomatous vasculitis involving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glomerulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bilateral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment.

    PubMed

    2014-06-01

    Subclavian steal syndrome (SSS) is usually caused by unilateral subclavian artery (SA) occlusion, and bilateral SSS is very rare. Takayasu's arteritis (TA) is a chronic granulomatous form of vasculitis that affects the SA, most commonly in women aged 15-40 years. We report a rare case of bilateral SSS due to TA in a 52-year-old woman, who exhibited severe vertigo. Although her blood pressure was within the normal range and did not differ between her arms, Doppler ultrasonography revealed low antegrade blood flow in the right SA and retrograde flow in the left SA. Computed tomography angiography demonstrated complete obstruction of the bilateral SA proximal to the vertebral artery origin. The more marked decrease in the blood flow of the vertebrobasilar artery experienced in bilateral SSS compared with unilateral SSS is considered to have caused the severe rotatory vertigo in the present patient. Since the vascular conditions of TA progressively deteriorate, delayed diagnosis and treatment could result in poor outcomes and unfavorable prognosis. We suggest that SSS with TA might require an early detection and treatment as well as careful follow-up for preventing vertigo and other neurological deficits in the vertebrobasilar arterial region.

    2011-05-01

    The wrist drop, also called carpoptosis or drop hand, is a common clinical presentation in case of peripheral damage to the radial nerve. But what about the picture of a bilateral finger/wrist drop?! We report the case of a 61-year-old female patient who was admitted to the hospital for myocardial infarction. Subsequently she developed a right dominant bilateral wrist drop. Further neurological examination revealed a positive Wartenberg sign pointing towards a central motoric dysfunction. The following native cerebral CT scan demonstrated bilateral hypodense lesions in both hand knobs in the precentral gyri. Subsequent MRI confirmed acute cerebral infarction in these two but also several other, clinically silent, locations. Further diagnostic work-up revealed a hypokinetic cardiac apex suggesting cardiac embolism to be the cause for cerebral thrombembolism and the clinically leading symptom of right-dominant bilateral finger/wrist drop. Besides the case presentation also the differential diagnosis and clinical test for diagnostic work-up of wrist drops are presented and discussed.

    2013-05-01

    We analysed the effects of task symmetry during bilateral accurate force production tasks performed by the two feet. In particular, we tested a hypothesis that bilateral deficit would lead to higher indices of synergies defined as co-varied adjustments in the two forces across trials that reduced total force variability. The subjects produced steady-state force followed by a quick force pulse into the target. The two feet could be acting both into plantar flexion and into dorsiflexion (symmetrical tasks), or in opposite directions (asymmetrical task). We used the framework of the uncontrolled manifold hypothesis to quantify two variance components, one of which did not change total force (V UCM), while the other did (V ORT). Synergy indices during the asymmetrical task were higher than in either symmetrical task. The difference was due to higher V UCM (compared to the symmetrical plantar flexion task) or lower V ORT (compared to the symmetrical dorsiflexion task). The synergy index showed a drop (anticipatory synergy adjustment, ASA) starting 100-150 ms prior to the force pulse initiation. The ASA tended to be shorter and of a smaller magnitude for the asymmetrical task. This is the first demonstration of bilateral synergies during accurate force production by the legs. We conclude that bilateral deficit has no or weak effects on two-leg synergies. The results fit the earlier introduced scheme with two groups of neural variables defining average performance of a redundant system and patterns of co-variation among its elemental variables, respectively.

    A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

  10. Color image diffusion using adaptive bilateral filter.

    PubMed

    Xie, Jun; Ann Heng, Pheng

    2005-01-01

    In this paper, we propose an approach to diffuse color images based on the bilateral filter. Real image data has a level of uncertainty that is manifested in the variability of measures assigned to pixels. This uncertainty is usually interpreted as noise and considered an undesirable component of the image data. Image diffusion can smooth away small-scale structures and noise while retaining important features, thus improving the performances for many image processing algorithms such as image compression, segmentation and recognition. The bilateral filter is noniterative, simple and fast. It has been shown to give similar and possibly better filtering results than iterative approaches. However, the performance of this filter is greatly affected by the choose of the parameters of filtering kernels. In order to remove noise and maintain the significant features on images, we extend the bilateral filter by introducing an adaptive domain spread into the nonlinear diffusion scheme. For color images, we employ the CIE-Lab color system to describe input images and the filtering process is operated using three channels together. Our analysis shows that the proposed method is more suitable for preserving strong edges on noisy images than the original bilateral filter. Empirical results on both nature images and color medical images confirm the novel method's advantages, and show it can diffuse various kinds of color images correctly and efficiently.

  11. Prosthetic rehabilitation of elderly bilateral amputees.

    1989-01-01

    A retrospective evaluation of vascular amputees, all over 55 years of age, found that 18 underwent bilateral lower limb amputation. The ages of patients ranged from 55 to 83 years, mean age at the time of second amputation was 65.9 years, 13 men and 5 women. Out of the 18 patients, 12 underwent bilateral below knee amputation (BK-BK), 3 below knee and above knee (BK-AK), and 3 bilateral above knee (AK-AK). Six patients (50%) of the 12 with BK-BK were fitted with prostheses. They therefore became users of two prostheses and have achieved a high functional level of rehabilitation despite a high mean age of 67.8 years. Five of these patients had been successful prosthetic users after the first leg amputation. The sixth patient underwent double BK amputation almost at the same time. He was fitted and rehabilitated with two prostheses simultaneously. Patients with BK-AK and AK-AK amputations had not been fitted with two prostheses. Deciding about prosthetic prescription and type of rehabilitation of elderly bilateral amputees is very difficult. Age alone is not a factor in success or failure of prosthetic rehabilitation. The type of rehabilitation for these patients is related mainly to the level of amputation, associated diseases and successful prosthetic use after the first leg amputation. Careful evaluation by a multidisciplinary team is the key for the right treatment decision and successful rehabilitation of this group of patients.

    Background Symptomatic bilateral internal carotid occlusive disease is a rare but potentially devastating entity. Medical therapy alone is associated with high rates of mortality and recurrent stroke. The optimal management of this disease remains poorly understood. Methods A retrospective review of a prospectively maintained database was conducted for patients who presented with an acute stroke in the setting of bilateral carotid occlusive disease between May and October 2013. Results We identified 3 patients. The admission National Institutes of Health Stroke Scale score ranged from 4 to 7. All patients had small- to moderate-sized infarcts in the anterior circulation on presentation. Angiography confirmed bilateral internal carotid occlusions with collateral filling via the posterior communicating artery and retrograde filling via external carotid artery supply to the ophthalmic artery. All patients were initially managed with permissive hypertension and anticoagulation followed by carotid angioplasty and stenting. At 1-year follow-up, all patients demonstrated a modified Rankin scale score of 0-1. Conclusions Carotid stenting may be a safe and effective therapy for patients presenting with symptomatic bilateral carotid occlusions. PMID:27051405

    Objective To investigate the mortality associated with cardiovascular diseases and the effect of estrogen treatment in women who underwent unilateral or bilateral oophorectomy before menopause. Design We conducted a cohort study with long-term follow-up of women in Olmsted County, MN, who underwent either unilateral or bilateral oophorectomy before the onset of menopause from 1950 through 1987. Each member of the oophorectomy cohort was matched by age to a referent woman from the same population who had not undergone any oophorectomy. We studied the mortality associated with cardiovascular disease in a total of 1,274 women with unilateral oophorectomy, 1,091 women with bilateral oophorectomy, and 2,383 referent women. Results Women who underwent unilateral oophorectomy experienced a reduced mortality associated with cardiovascular disease compared with referent women (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67–0.99; P = 0.04). By contrast, women who underwent bilateral oophorectomy before age 45 years experienced an increased mortality associated with cardiovascular disease compared with referent women (HR, 1.44; 95% CI, 1.01–2.05; P = 0.04). Within this age stratum, the HR for mortality was significantly elevated in women who were not treated with estrogen through age 45 years or longer (HR, 1.84; 95% CI, 1.27–2.68; P = 0.001) but not in women treated (HR, 0.65; 95% CI, 0.30–1.41; P = 0.28; test of interaction, P = 0.01). Mortality was further increased after excluding deaths associated with cerebrovascular causes. Conclusions Bilateral oophorectomy performed before age 45 years is associated with increased cardiovascular mortality, especially with cardiac mortality. However, estrogen treatment may reduce this risk. PMID:19034050

    2015-01-01

    Flash pulmonary edema is characteristically sudden in onset with rapid resolution once appropriate therapy has been instituted (Messerli et al., 2011). Acute increase of left ventricular (LV) end diastolic pressure is the usual cause of sudden decompensated cardiac failure in this patient population. Presence of bilateral renal artery stenosis or unilateral stenosis in combination with a single functional kidney in the susceptible cohort is usually blamed for this condition. We describe a patient who presented with flash pulmonary edema in the setting of normal coronary arteries. Our case is distinct as our patient developed flash pulmonary edema secondary to unilateral renal artery stenosis in the presence of bilateral functioning kidneys. Percutaneous stent implantation in the affected renal artery resulted in rapid resolution of pulmonary edema. PMID:25793128

    2015-01-01

    Purpose of review Renal dysfunction causes significant morbidity in cirrhotic patients. Diagnosis is challenging because it is based on serum creatinine, which is used to calculate estimated glomerular filtration rate, which itself is not an ideal measure of renal function in patients with cirrhosis. Finding the exact cause of renal injury in patients with cirrhosis remains problematic due to the limitations of the current diagnostic tests. The purpose of this review is to highlight studies used to diagnose renal dysfunction in patients with renal dysfunction and review current treatments. Recent findings New diagnostic criteria and classification of renal dysfunction, especially for acute kidney injury (AKI), have been proposed in hopes of optimizing treatment and improving outcomes. New biomarkers that help to differentiate structural from functional AKI in cirrhotic patients have been developed, but require further investigation. Vasoconstrictors are the most commonly recommended treatment of hepatorenal syndrome (HRS). Given the high mortality in patients with type 1 HRS, all patients with HRS should be evaluated for liver transplantation. When renal dysfunction is considered irreversible, combined liver–kidney transplantation is advised. Summary Development of new biomarkers to differentiate the different types of AKI in cirrhosis holds promise. Early intervention in cirrhotic patients with renal dysfunction offers the best hope of improving outcomes. PMID:25763790

In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB) facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT) examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis. PMID:26175920

    We report a case of a 55-year-old man with ischemic lesions of the bilateral hippocampus and bilateral basal ganglia following a myocardial infarction during an episode of multiple drug use with subsequent anoxia requiring resuscitation. He presented for a neuropsychological evaluation with an anterograde amnesia for both explicit and procedural memory. There are two main points to this case, the unique aspects of the bilateral multifocal lesions and the functional, cognitive impact of these lesions. We hypothesize that his rare focal bilateral lesions of both the hippocampus and basal ganglia are a result of anoxia acting in synergy with his stimulant drug use (cocaine and/or 3,4-methylenedioxy-methamphetamine). Second, his unique lesions produced an explicit and implicit/procedural anterograde amnesia. PMID:28228745

    One year ago, a 48-year-old man complained of dyspnea, and was diagnosed as mitral valve regurgitation and aortic dissection. He underwent mitral valve replacement and aortic arch grafting. He was also pointed out to have an inflammatory aortic aneurysm (IAAA) in the infrarenal abdominal aorta, but did not undergo surgery. At this admission, he had lumbago and low grade fever probably due to deterioration of the IAAA. On the preoperative radionuclide studies, inferior vena caval obstruction and bilateral ureteral obstruction or severe stenosis were demonstrated by 99mTc-MAA venography and 123I-OIH renogram, respectively. 67Ga scan showed faint abnormal accumulation at the IAAA. He underwent surgery. IAAA had a thick wall in white and hard fibrotic tissue adhered closely to duodenum, jejunum, inferior vena cava and bilateral ureters. After surgery, his renal function was improved. In this case, radionuclide studies were useful for detecting the inferior vena caval obstruction, assessing renal function and inflammatory activity.

    The rates of perioperative morbidity and mortality are areas of concern associated with simultaneous bilateral total knee replacement. The purpose of this paper was to compare the rates of morbidity and mortality and the clinical outcome in large groups of consecutive patients undergoing simultaneous bilateral total knee replacement, unilateral total knee replacement, or staged bilateral total knee replacement. A total of 6200 total knee replacements, performed in 3998 patients between 1983 and 2000, consisted of 2050 simultaneous bilateral, 1796 unilateral, and 152 staged bilateral total knee replacements. A review of each group was conducted to compare the rates of morbidity and mortality, the survival of the prosthesis, and the clinical outcome. Kaplan-Meier survival analyses were performed with failure defined as revision because of aseptic loosening and as patient death. Complications and Knee Society scores were compared throughout the fifteen-year follow-up period (average, 4.3 years of follow-up). The unilateral group had significantly lower Knee Society scores than the simultaneous bilateral group (p < 0.0001 up to twelve years, and p = 0.0067 at fifteen years) across all postoperative time-intervals. The percentage of patients who had thrombophlebitis was significantly higher in the simultaneous bilateral group (0.9%) than in the unilateral group (0.3%) (p = 0.0326). No significant differences were found with regard to prosthetic failure, cardiac complications, and the rates of death in the three groups. Ten years postoperatively, the simultaneous bilateral group had a significantly higher rate of patient survival than did the unilateral group (78.6% compared with 72.0%) (p = 0.0062). The significantly higher rate of thrombophlebitis in the simultaneous bilateral group compared with that in the unilateral group may represent a greater risk to those patients. However, we believe that when there are adequate indications for bilateral total knee replacement

  8. Atheroembolic renal disease.

    PubMed

    Scolari, Francesco; Ravani, Pietro

    Atheroembolic renal disease develops when atheromatous aortic plaques rupture, releasing cholesterol crystals into the small renal arteries. Embolisation often affects other organs, such as the skin, gastrointestinal system, and brain. Although the disease can develop spontaneously, it usually develops after vascular surgery, catheterisation, or anticoagulation. The systemic nature of atheroembolism makes diagnosis difficult. The classic triad of a precipitating event, acute or subacute renal failure, and skin lesions, are strongly suggestive of the disorder. Eosinophilia further supports the diagnosis, usually confirmed by biopsy of an affected organ or by the fundoscopic finding of cholesterol crystals in the retinal circulation. Renal and patient prognosis are poor. Treatment is mostly preventive, based on avoidance of further precipitating factors, and symptomatic, aimed to the optimum treatment of hypertension and cardiac and renal failure. Statins, which stabilise atherosclerotic plaques, should be offered to all patients. Steroids might have a role in acute or subacute progressive forms with systemic inflammation.

    Renal angiomyoadenomatous tumour is a newly described rare neoplasm. This tumour is characterised microscopically by admixture of three components- epithelial cells arranged in tubules and nests, angiomyomatous stroma and capillary sized interconnecting vascular channels in close association with the epithelial cell clusters. Microscopically it has wide range of differential diagnoses which include mixed epithelial and stromal tumour of kidney, angiomyolipoma and clear cell renal cell carcinoma with angiomyolipomatous/angiomyoadenomatous areas. Renal angiomyoadenomatous tumour should be differentiated from these tumours. Till now, only 10 cases have been reported in English medical literature. Here, we are reporting a case of renal angiomyoadenomatous tumour in a 29 year- old female patient who presented with hematuria and low backache and describing its main features so as to differentiate this entity from other renal tumours. To the best of our knowledge, this is the first case to be reported from India.

    Renal involvement in sarcoidosis is much more common than generally assumed from old epidemiological studies and is often only detected when actively searched for. Many patients with renal sarcoidosis present with no or only few symptoms. The diagnostic work-up of sarcoidosis should always include a possible renal involvement. In cases of impaired renal function, proteinuria or a pathological urine sediment, a renal biopsy specimen should be obtained to assess the type, severity and prognosis of the kidney disease. Treatment is primarily based on the use of corticosteroids. Steroid-sparing agents, such as disease-modifying antirheumatic drugs and infliximab can be applied; however, the evidence for efficacy of these therapies is mostly based on case series and expert opinions. Discontinuation of immunosuppression therapy bears a high risk of relapse.

    Renal papillary necrosis was diagnosed during postmortem examination of a juvenile white-tailed deer (Odocoileus virginianus) from Oklahoma. The deer was surgically treated for a Salter Harris type II fracture of the proximal tibia of the left hind limb. The animal was administered multiple nonsteroidal anti-inflammatory drugs (NSAIDs), including meloxicam, flunixin meglumine, and ketoprofen for pain management. At postmortem examination, gross lesions included a proximal tibial Salter Harris type II fracture with an associated fibrinonecrotizing myositis and bilateral renal papillary necrosis. Histologically, the kidneys exhibited coagulation necrosis of the renal medulla and renal papilla, thrombosis of renal blood vessels, and interstitial medullary edema. The gross and microscopic lesion coupled with the clinical history of multiple NSAID administration suggests NSAID-induced renal papillary necrosis.

    Autosomal-dominant polycystic kidney disease (ADPKD) is a systemic disease, marked by progressive increase of bilateral renal cysts, resulting in chronic kidney disease (CKD) and often leading to end-stage renal disease (ESRD). Apart from renal cysts, patients often have extra-renal disease, involving the liver, heart and vasculature. Other less common but equally important extra-renal manifestations of ADPKD include diverticular disease, hernias, male infertility and pain. Extra-renal disease burden is often asymptomatic, but may result in increased morbidity and mortality. If the disease burden is significant, screening may prove beneficial. We review the rationale for current screening recommendations and propose some guidelines for screening and management of ADPKD patients.

    The kidneys of long term dialysis patients frequently demonstrate multiple small acquired cysts and renal cell tumors on pathologic examination. The original kidneys of 30 long-term dialysis patients and six renal transplant patients were evaluated by computed tomography to determine the incidence of these abnormalities. Among dialysis patients, 43.3% had diffuse bilateral cysts, while 16.7% had occasional cysts (fewer than five per kidney), and 40% showed no renal cysts. Seven solid renal tumors were detected in four dialysis patients with renal cysts. Acquired cystic kidney disease tends to result in renal enlargement, is more common in patients who have been maintained on dialysis for prolonged periods, and may lead to spontaneous renal hemorrhage. The six transplant patients showed no evidence of renal cysts, and all had markedly shrunken kidneys. Acquired cystic disease and renal cell tumors in the original kidneys of dialysis patients may be due to biologically active substances that are not cleared effectively by dialysis but that are removed by normally functioning transplant kidneys.

  14. Hardware Implementation of a Bilateral Subtraction Filter

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    A comparison of bimodal hearing and bilateral cochlear implants (CIs) was completed using a within-subjects, repeated-measures study for eight adult sequential recipients who despite achieving incredibly high performance with the first CI, self-selected for bilateral implantation. Speech understanding was assessed with the minimum speech test battery (MSTB) as well as sentences in semi-diffuse noise using the R-SPACE™ system. Conditions included unilateral hearing aid (HA) in the non-implanted ear, unilateral CI, bimodal (CI+HA), and bilateral CI. Additionally, three participants had bilateral hearing preservation and were also tested with bilateral CIs and bilateral HAs (BiBi). All testing was completed in the bimodal hearing configuration and repeated at least six months following activation of the second CI. Bilateral CIs afforded significant individual improvement in a complex listening environment even for individuals demonstrating near perfect sentence scores with both the 1st CI alone as well as the bimodal condition. The 3 BiBi participants demonstrated additional significant benefit over the bilateral CI condition—presumably due to the availability of interaural time difference cues. These data suggest that for noisy environments, adding a second implant can significantly improve speech understanding—even for high performing unilateral CI with bimodal hearing. In diffuse noise conditions, bilateral acoustic hearing can yield even greater benefit beyond that offered by bilateral implantation. PMID:26164443

    We report the first case of both endocarditis and bilateral septic arthritis in a patient caused by Moraxella lacunata and successful management of the infection with antimicrobial therapy. The route of entry leading to bacteremia may have been the oral cavity given the poor oral hygiene of the patient as evidenced by bleeding gums. We hypothesize that the bacteremia led to septic arthritis and mitral valve infective endocarditis. In this case report, we also review the literature on M. lacunata infections and conclude that this organism should be considered in bilateral septic arthritis in a patient with underlying heart abnormalities and/or with renal failure.

    Although traumatic injury of the facial nerve is a relatively common condition in neurosurgical practice, bilateral lesions related to fracture of temporal bones are seldom seen. We report the case of a 38-year-old patient admitted to Intensive Care Unit after severe head trauma requiring ventilatory support (Glasgow Coma Scale of 7 on admission). A computed tomography (CT) scan confirmed a longitudinal fracture of the right temporal bone and a transversal fracture of the left. After successful weaning from respirator, bilateral facial paralysis was observed. The possible aetiologies for facial diplegia differ from those of unilateral injury. Due to the lack of facial asymmetry, it can be easily missed in critically ill patients, and both the high resolution CT scan and electromyographic studies can be helpful for correct diagnosis.

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions.

    Fibroadenomas are benign lesions of breast commonly found in young age group. These focal tumours contain both mesenchymal and glandular tissue. Giant juvenile fibroma of breast is rare variant of fibroadenoma found usually in less than 20 years of age. They present with rapid enlargement of single or multiple, discrete, painless large nodule of breast. A 14-years-old premenarche girl presented with large bilateral breast lumps for two months. FNAC showed features of juvenile fibroadenoma. Breast conserving surgical excision of lumps was performed and histopathology confirmed the diagnosis of juvenile fibroadenoma. Giant juvenile fibroadenomas are characterised by rapid enlargement of encapsulated mass. The aetiology is unknown, although end-organ hypersensitivity to normal level of estrogen is postulated. We present a case of bilateral giant juvenile fibroadenoma for its rarity.

    Sudden bilateral hearing loss are seen rarely and the toxic substance exposure constitutes a small part of etiology. A Fifty-eight-year-old woman admitted to our clinic with sudden bilateral hearing loss shortly after chlorpyrifos-ethyl exposure. Otolaryngologic examination findings were normal. The patient had 40 dB sensorineural hearing loss (SNHL) on the right ear and 48 dB SNHL on the left ear. Additional diagnostic tests were normal. The conventional treatment for sudden hearing loss was performed. On the second week following organophosphate (OP) exposure the patient's hearing loss almost completely resolved. OP's are heavily used in agriculture and should be taken into consideration as an etiologic factor in sudden hearing loss.

    Anatomical variations of the biceps brachii have been described by various authors, but the occurrence of bilateral asymmetric supernumerary heads is rare and has not been reported. We found three accessory heads of the biceps brachii muscle on right arm and an anomalous third head of biceps brachii on left arm. The third, fourth, and fifth heads of right arm originated from the body of humerus at the insertion site of coracobrachialis and inserted into the distal part of biceps brachii short head in order. The third head of left arm originated from humerus at the insertion site of coracobrachialis and combined with the distal part of biceps brachii and continued to the proximal part of common biceps tendon. Understanding the existence of bilateral asymmetric supernumerary heads of biceps brachii may influence preoperative diagnosis and surgery on the upper limbs. PMID:22025976

    We present a case of bilateral hematoma in cerebellar hemispheres in a 30-year-old man after surgical treatment of extensive left frontal glioma. 16 hours after surgery the patient lost consciousness. An immediate CT revealed hematoma in both cerebellar hemispheres. The hematoma was subsequently removed via bilateral suboccipital craniectomy. After the operation the clinical status of the patient gradually improved - he was discharged in a good general condition. In the presented case the hematoma developed presumably as a consequence of extensive cerebrospinal fluid (CSF) loss (670 ml) via postoperative wound drainage. The resulting cerebellar displacement caused strain of the draining veins, affecting blood outflow, and causing parenchymal hemorrhage. In order to prevent the complication, massive CSF loss during and after operation should be avoided. Careful monitoring of the patient's condition in the postoperative period, even if the general status is good, is important because only an immediate intervention may prevent the development of irreversible consequences of cerebellar hematoma formation.

    We report a case of bilateral orbital hemorrhage as a complication of peribulbar anesthesia in a 78 year old man. Initially, unilateral orbital hemorrhage occurred but quickly spread to the contralateral side. Neuroophthalmological assessment revealed a proptosed tense globe with normal retinovascular findings. Visual acuity was adversely affected and this was conservatively managed with no lasting ophthalmic sequela. This patient’s case was reported as it illustrates an unusual complication of bilateral spread of orbital hemorrhage secondary to peribulbar anesthesia. It highlights how early ophthalmic assessment can ensure a good visual outcome in the setting of appropriate ophthalmic monitoring. The mechanisms of orbital hemorrhage spread and appropriate management options are discussed. PMID:27013899

    To report sequential bilateral uveal melanoma in an arc welder. Case report. A 57-year-old Caucasian male, with a 15-year profession of arc welding, was found to have an iridociliary mass in his left eye (OS), measuring 14 × 10 × 4 mm, and proven on fine needle aspiration biopsy to be spindle B-cell melanoma. A coincidental small choroidal nevus was observed in the right eye (OD). There was no ocular melanocytosis. Plaque radiotherapy was applied OS, with regression of the iridociliary melanoma. Four years later, the choroidal nevus OD enlarged into melanoma measuring 8 × 7 × 2.7 mm and was treated successfully with plaque radiotherapy. There was no evidence of systemic metastasis at 56-month follow-up. Arc welding is a known environmental risk for unilateral uveal melanoma, and possibly predisposed our patient to bilateral uveal melanoma.

    Methods: 17 patients with Parkinson's disease were evaluated with a neuropsychological battery before and six months after bilateral pallidotomy. A comparison group (n = 8) was also assessed at six month intervals. Outcome variables were tests of memory, language, visuospatial function, attention, executive skills, and depression. Results: Despite a large number of variables studied, a significant postsurgical change was found only in performance of the tower of London task, a measure of planning abilities. The effect size of this change was larger than that of the comparison group, and a reliable change index score established that 5 of 13 surgical patients had statistically reliable reductions in planning performance. Conclusions: Patients with a young age of onset and long duration of Parkinson's disease who underwent bilateral pallidotomy had a relatively circumscribed reduction in neuropsychological functioning, being limited to motor planning efficiency. These data suggest that the cognitive role of the posteroventral globus pallidus is limited, at least in people with Parkinson's disease. PMID:12235317

    A 49-year-old female victim of violent crime with an acute bilateral loss of vision was referred to our hospital. The ophthalmological evaluation showed complete subconjunctival hemorrhage of both eyes, bilateral hemophthalmos and hypotonia of the left eye. These raised the suspicion of an occult scleral rupture. We immediately performed exploratory surgery and found a perforating scleral lesion of the left eye and a penetrating scleral lesion of the right eye. Furthermore, a small, cruciform wound was detected on the left temple. In cooperation with the department of radiology, the extraordinary injury pattern was reconstructed: a horizontal stab wound with perforation of the left eye and penetration of the right eye caused by a screwdriver. Visual rehabilitation necessitated further surgical interventions. Besides the intraoperative approach, immediate primary wound management within 100 h of trauma plays a pivotal role for long-term outcome.

    Spinal anaesthesia is one of the most widely used regional anaesthesia techniques. Sudden bilateral hearing loss following spinal anaesthesia has only been reported in a few cases. This paper reports the case of a 50-year-old woman who developed sudden bilateral hearing loss following spinal anaesthesia for hallux valgus orthopaedic surgery. This is followed by a literature review. The patient's hearing improved almost completely on the morning of the 3rd day following surgery. No recurrence of hearing loss, tinnitus or vertigo was reported during the six-month follow-up period. Some complications regarding hearing may emerge after spinal anaesthesia. The possibility of hearing loss after spinal anaesthesia should be taken into consideration. Complaints such as hearing loss, tinnitus or vertigo should be taken seriously when reported, and the patient should be referred to an ENT clinic. This will ensure early diagnosis and treatment.

    Background Accessory carpal ossicles may be the cause of atraumatic wrist pain or may be misinterpreted as a fracture after a trauma. Case Description We report the case of a patient suffering with chronic, bilateral wrist pain without history of trauma. Sonographic examination showed a bilateral symptomatic os epilunatum, both of which were surgically resected, resulting in pain relief. Literature Review Os epilunatum is a rare entity that has been reported only in few cadaveric specimen. Clinical Relevance Os epilunatum is a rare accessory ossicle of the carpus that can cause this aggravating pain. Sonography enabled accurate diagnosis of this anomaly. Because of possible associated tear of the scapholunate ligament, we recommend intraoperative testing of the stability of the scapholunate joint. PMID:25709883

    Autotransplantation, with or without an extracorporeal renal operation, has been done 39 times in 37 patients. Indications for the procedure included several ureteral injury in 4 patients, failed supravesical diversion in 2, renal carcinoma in a solitary kidney in 1, renovascular hypertension in 1 and donor arterial reconstruction before renal transplantation in 29. Success was obtained in all but 2 procedures, both of which involved previously operated kidneys with severe inflammation and adhesions involving the renal pelvis and pedicle. Based on our experience and a review of currently available literature we believe that renal autotransplantation and extracorporeal reconstruction can provide the best solution for patients with severe renovascular and ureteral disease not correctable by conventional operative techniques. The technique can be of particular value in removing centrally located tumors in solitary kidneys and in preparing donor kidneys with abnormal arteries for renal transplantation. The role of autotransplantation in the management of advanced renal trauma and calculus disease is less clear. A long-term comparison of patients treated by extracorporeal nephrolithotomy versus conventional lithotomy techniques will be necessary before a conclusion is reached in these disease categories.

    Lymphangiomatous polyps of the tonsils are rare with less than 30 cases reported in the literature. All have been unilateral. We report a case of a child with bilateral lymphangiomatous polyps of the palatine tonsils that was suspected on preoperative examination as opposed to an incidental postoperative histologic finding. These findings were also correlated with a further imaging study to establish this entity as a localized rather than a generalized histologic phenomenon. Copyright (c) 2009 Elsevier Ireland Ltd.

    2015-01-01

    Patient: Male, 21 Final Diagnosis: Idiopathic bilateral external jugular vein thrombosis Symptoms: Face engorgement • neck swelling Medication: — Clinical Procedure: None Specialty: Hematology Objective: Unknown ethiology Background: Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow’s triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. Case Report: This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Conclusions: Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present

    To determine the frequency and causes of bilateral ocular trauma. A descriptive case series. Khyber Institute of Ophthalmic Medical Sciences, Hayatabad Medical Complex, Peshawar from October 1999 to September 2006. All patients coming to the hospital with bilateral eye trauma and requiring admission were recruited into the study. The details of patients' demographics, risk factors, ocular examination, treatment offered and final visual acuity were noted and described as frequency and percentages. Out of a total of 1551 patients of hospitalized ocular trauma, 46 (2.9%, 92 eyes) had bilateral ocular trauma. The majority (54.3%) were due to landmine blast injuries followed by dynamite blast in 10.8%, coalmine blast and firearm injury in 6.5% each. Pressure cooker explosion and road traffic accident was the cause in 4.3% each. Gas cylinder and automobile battery explosion, alkali and acid burn, assault and incidental trauma occurred in 2.1%. Sixty three percent were between 16 and 40 years of age. Males were affected in 93.4%. Corneal and / or scleral repair was done in 58.6%, conjunctival and or corneal foreign body removal in 26% and extracapular cataract extraction with intraocular lens implantation in 16.3%. The visual acuity was in the range of 6/60 and perception of light in 54.3%, while in 21.7%, there was no perception of light at the time of admission. Due to severity of injury, the final visual acuity was poor and only 28.2% regained vision between 6/18 and 6/60. In this series, landmine, dynamite and coalmine blasts were the major causes of bilateral ocular trauma. Victims were usually young males. Due to severity of ocular trauma, majority had poor visual outcome.
