Abstract
Implant placement is a challenge in the anterior maxilla if the available bone is reduced and esthetics is challenging. The ideal implant position should be considered in all three dimensions: mesiodistal, apicocoronal, and orofacial. This article includes a review and a case report for the anatomical and clinical perspective of implant placement in nasopalatine foramen (near incisal canal). In this case report, the edentulous space is mutilated in between the area #12 and #21 teeth. Therefore, only one, 3.0 W/10.00 L implant (bone size 4.2 mm width and 11 mm length) could be placed. Radiographically, D2 bone quality was diagnosed. Before surgery, an emphasis was given over the proper implant selection to avoid oversized implants due to critical anatomical landmark. Careful and with minimal trauma, the soft tissue was handled and implant placement was performed in a proper position, using information from panoramic radiograph, 3-D Dentascan. A surgical guide was used for placement of the implant. Finally, immediate loading of temporary implant prosthesis was done. The primary outcome was satisfactory, as after 72 h, no swelling and numbness were reported. The patient has been recalled after healing period of 24 weeks for permanent restoration.

Abstract
The rationale for implant full-mouth rehabilitation is believed to present the better quality of life to the older population. This type of modalities preserves the soft and hard tissue of oral cavity. It is also helpful to check the temporomandibular joint disease. Literature exposes that implant full-mouth fixed rehabilitation is one of the taxing procedures in the field of prosthodontics. The current clinical report discusses a customized biomechanical approach for the fabrication of implant complete-mouth rehabilitation. A systematic approach in managing this patient can lead to a predictable and favorable prognosis. This article also presents the stages of prosthodontic rehabilitation from diagnosis to final treatment planning as a customized radiographical Gutta Percha template, precise implant surgery of 12 implants (ADIN, Dental Implant System, Israel) over the both the arches and provisional restorations with group function occlusion. Lastly, full-mouth restorations were fabricated as cement-retained (open hole) metal-ceramic restoration. Advocated patient is absolutely happy with customized implant full-mouth rehabilitation.

Abstract
A maxillofacial patient's quality of life is distorted and social integration becomes difficult. An obturator is a maxillofacial prosthesis used to close a congenital or acquired tissue defect, primarily of the hard palate and/or contiguous alveolar/soft-tissue structures. Subsequently, it restores the esthetics, speech, and function. The present clinical report aimed for the prosthetic rehabilitation of a maxillectomy defect by the incorporation of a semi-precision attachment as PRECI-SAGIX - male part of 2.2 mm on fixed partial denture (#22 and #23 teeth) and matrix - plastic female part of size 2.2 mm and height 4.2 mm of yellow on cast partial in polymer base. It aids in the retention of a hollow lightweight obturator. The technique also described the method to make a bulbless obturator with a hollow self-cured acrylic resin occlusal shim. A patient is quite satisfied with bulb less, lightweight cast partial and hollow shim palatal obturator.

Abstract
Successful rehabilitation of a patient should restore function, esthetic, and speech by prosthesis. Treatment modalities vary from patient to patient. Semi-precision attachments and implants offer several advantages over the traditional approach. The aim and objective of this report was to assess a case of a 55-year-old female patient who had lost all her teeth, except maxillary canines #13 and #23 and with severe bone loss in the mandible. Tooth-supported bar attachment was planned for maxilla, and a total of five dental implants were placed in the mandible using a flapless approach aided by radiographic gutta-percha surgical stents over panoramic two-dimensional imaging. Customized, radiographic stents help for the placement of implant in the view of paralleling and flapless surgery, completely. An immediate loading protocol is adopted as from day of the surgery to 6 weeks along with implant supported full arch fixed dentures after 4 months. The outcome of the treatment was impressive, and the patient gave a positive response with superb esthetics and functions.

Abstract
The eye is a vital organ and an important component of facial expression. Loss of an eye has a crippling effect on the psychology of the patient. Maxillofacial prostheses restore and replace stomatognathic and associated facial structures with artificial substitutes. The objectives of eye prosthesis is to improve the patient esthetics, restore and maintain the health of the remaining associated structures, consequently provide physical and mental well-being. The primary purpose of an ocular prosthesis is to maintain the volume of eye socket and create the illusion of a healthy eye and surrounding tissue. A custom ocular prosthesis is a good option when reconstruction is done by plastic surgery, and osseointegrated implants are either not possible or not desired. A case of a custom-made ocular acrylic prosthesis is presented with acceptable fit, good retention, and esthetics.

Abstract
Perivascular epithelioid cell tumor (PEComa) is a group of sarcomas that exhibit a myomelanocytic phenotype and possess a unique cell type in the perivascular epithelioid cell. Traditionally HMB-45 immunoreactivity is the first criteria required to consider a tumor to be PEComa. We report a case of multifocal PEComa with negative HMB-45 marker. The patient presented with three big ulceroproliferative lesions; two over right thigh and one over the scalp in the right frontal region. The patient was prescribed with oral sirolimus to which good response was seen. To the best of our knowledge, this is the first case of HMB-45 negative multifocal malignant PEComa from India.

Abstract
Introduction: Acute myeloid leukemia (AML) in elderly patients differs biologically from that in younger patients and is known to have unfavorable chromosomal rearrangements, higher resistance, and lower tolerance to chemotherapy. In such circumstances, instead of giving full-blown chemotherapy, palliative metronomic chemotherapy (MCT) could be a treatment option. Patients and Methods: We performed a prospective pilot study of old AML patients (age >60 years) not amenable to curative treatment. Thirty-two patients were enrolled into the study and were treated with daily oral 6-mercaptopurine 75 mg/m2. The following inclusion criteria were used: age >60 years, nonpromyelocytic AML, the absence of uncontrolled comorbidities, and patient not amenable to curative treatment. Overall survival (OS) was calculated using Kaplan–Meier method and Cox regression analysis were used to calculate the hazards ratio of significant factors. Results: The median age of the patients was 69 years (range: 61–86 years) with male: female ratio of 2.5:1. About 59.4% of patients had Eastern Cooperative Oncology Group performance status of 2 while rest had the status of 3. The median OS was 6 months (95% confidence interval [CI]: 4.4–7.6). Males had median OS of 7 months (95% CI: 5.4–8.6) versus females with OS of 3 months (95% CI: 1.5–4.4; P = 0.008). There was no survival difference on the basis of baseline hemoglobin or French-American-British class. There were no Grade 4 toxicities and no episode of febrile neutropenia. Conclusions: MCT with oral 6-mercaptopurine is an attractive treatment option in elderly AML patients who are not amenable to curative therapy with minimal toxicities.

Abstract
Background: A dramatic improvement in the survival of acute lymphoblastic leukemia (ALL) patients in the last three decades has been observed. MCP 841 protocol is an old but effective tool with tolerable toxicities. The objective of this study was to estimate the relapse-free survival of ALL patients treated uniformly with MCP 841 protocol on the basis of various prognostic factors. Materials and Methods: The study design was retrospective and it was conducted in a regional cancer center of Northwest India. Three hundred and ten ALL patients who underwent treatment with MCP 841 protocol and regular follow-up for up to 5 years were selected for this study. Relapse-free survival was calculated by Kaplan–Meier analysis and Cox regression analysis was used to calculate the hazards ratio (HR) using Statistical Package for the Social Sciences (SPSS) software for windows version 20.0. Results: Fifty-four percent patients were <15 years of age and 69% were males. 53.2% patients were in remission at the end of 5 years of starting the treatment. Relapse-free survival at 5 years by Kaplan–Meir analysis for B-cell ALL was 62% [HR 0.67 {95% confidence interval (CI) 0.47-0.95}] with patients with unknown lineage taken as reference] while for T cell it was 28% [HR 1.41 (95% CI 1.19-1.63), P 0.001]. Patients with total leukocyte count (TLC) <1 lakh/cmm at presentation, relapse-free survival was 68% and those with TLC >1 lakh/cmm had 41% survival [HR 2.14 (1.76-2.48) with, P < 0.001]. Conclusion: MCP 841 protocol is a useful tool for the treatment of ALL in children when more aggressive protocols can not be used.

Abstract
Astroblastoma is a rare neuroepithelial primary brain tumor of uncertain origin. They form 0.45-2.8% of all the neuroglial tumors. This tumor is usually localized in the cerebral hemisphere of young adults and children. The authors report a case of low-grade astroblastoma in a 16-year-old male and review the relevant literature. The patient presented with 2 months history of progressive headache with projectile vomiting for last 2 months. He underwent gross total resection of the lesion through right temporo-occipital craniotomy. Since tumor showed no evidence of high-grade lesion, adjuvant radiotherapy was not planned. However, the patient developed recurrence of the tumor after 12 months. Localized three-dimensional conformal radiotherapy was planned. In patients harboring anaplastic astroblastoma, gross-total resection and adjuvant therapy after the initial surgery seems to be the best choice. They can be easily misdiagnosed as they are rarely encountered in clinical practice and share common radiological and histopathologic appearance with other glial neoplasms.

Abstract
Background: Despite various advances in the treatment of Esophageal Cancer (EC), being one of the least responsive tumors to cancer therapy, the overall prognosis remains poor. Therefore, it is significant to understand various sociodemographic factors associated with EC to find out various schemes for primary prevention of the disease. Materials and Methods: This is a retrospective analysis of medical records of the EC patients registered in the regional cancer center of northwest India from January 2003 to December 2012. The site of the disease and the histology were also recorded in addition to the various sociodemographic parameters. Results: Out of 55,742 patients registered in our hospital; 3,667 were diagnosed to have EC. Male:female ratio was 1.15:1. The mean age was 54.6 ± 11.74 years; 66.15% of the patients were illiterate and 48.6% belonged to the low socioeconomic status. Smoking and alcohol consumption were identified as risk factors in 48 and 25.6% of the patients, respectively. Conclusions: The etiology in majority of the patients is linked to tobacco and alcohol, thus, modification of life style with limiting the use of addictions may be an effective strategy in the prevention of this dreaded and mostly incurable disease.

Abstract
Background: Palliative radiotherapy (PRT) is the eventual requirement in 30-50% of all cancer patients. PRT is primarily aimed to relieve pain and prevent/treat collapse or fracture in case of bone metastasis, to reduce edema in patients with cranial metastasis, and to control distressing symptoms of rapid primary growth. An audit of PRT planned in a busy cancer center can help in the characterization of the requirements of the patients and the formulation of institutional policies. Materials and Methods: In total, 516 patients who received PRT in our regional cancer center from January 2012 to December 2012 and whose complete records were available for analysis were selected for this retrospective study. Medical records and radiotherapy files were analyzed to obtain data such as sociodemographic parameters, prescription of PRT, and follow up. Descriptive statistics were evaluated in terms of frequencies and percentages to allow comparisons. Results: Of the 516 patients, 73% patients were male; the median age of the patients receiving PRT was 62 years (range 13-83 years). About 48% (n = 248) patients received PRT at the primary site while rest (52%) were given PRT at the metastatic site. The most common indication of PRT was pain (56.8% cases), followed by cytostatic PRT (19.8%) and raised ICT (12.4%). The median dose prescribed was 30 Gy (range 8-36 Gy) delivered in 1-12 fractions over the duration of 1-18 days. The overall response rate was about 43% at 2 weeks of completion of PRT; the median follow-up of the patients was 154 days (range 9-256 days). The long-term symptom relief at median follow up was 8%. Conclusions: Good clinical judgment and expertise is required in prescribing correct fractionation schedule to achieve effective symptom palliation with lowest possible cost and inconvenience to the patients and relatives. Hypofractionated radiotherapy is a feasible treatment option in patients with advanced incurable disease to achieve effective palliation.

Abstract
Introduction: Postoperative radiotherapy is the current gold standard treatment in astrocytomas. Computed tomography (CT)-based radiotherapy planning leads to either missing of the tumor volume or underdosing. The aim of this prospective study was to study the changes in tumor volume on addition of magnetic resonance imaging (MRI) to CT-based three-dimensional radiotherapy treatment planning of astrocytomas. Materials and Methods: Twenty-five consecutive patients of astrocytoma (WHO grades I-IV) for postoperative three-dimensional conformal radiotherapy were included in this prospective study. Postoperative tumor volumes were contoured on CT-based images and recontoured on CT-MRI images after automated MRI co-registration on treatment planning system Eclipse 8.9.15 as per ICRU-50 report. Tumor volumes were compared with each other. Result: The MRI-based mean and median tumor volume was 24.24 cc ± 13.489 and 18.72 cc (range 5.6–46.48 cc), respectively, while for CT it was 19.4 cc ± 11.218 and 16.24 cc (range: 5.1-38.72 cc), respectively. The mean and median isocenter shift between CT and MRI was 4.05 mm and 4.39 mm (range 0.92–6.32 mm), respectively. There is a linear relationship between MRI and CT volume with a good correlation coefficient of R2 = 0.989, and MRI-based tumor volume was 1.208 times as compared to CT volume. Statistical analysis using paired sample t-test for the difference in CT and MRI tumor volume was highly significant (P < 0.001). Conclusion: Addition of MRI to the CT-based three-dimensional radiation treatment planning reduces the chances of geographical miss or tumor under dosing. Thus, MRI should be an integral part of three-dimensional planning of astrocytomas.

Abstract
Background: Cancer related fatigue (CRF) is a problem that is highly under reported, under recognized and thus, under treated. About 80% of patients receiving chemotherapy/radiotherapy experience CRF, making it the most common side effect of cancer treatment. Functional assessment of chronic illness therapy fatigue (FACIT-F) version-4 is a 13 item questionnaire that has been used to measure the level of fatigue of cancer patients during their daily activities over the past 7 days. Materials and Methods: 92 patients of age 18 years and above attending the oncology Out Patient Department (OPD) of a regional cancer center were recruited in this study and were given FACIT-F questionnaire. The relevant sociodemographic parameters were obtained from the medical records of the patients. The internal consistency of the 13 items was measured using the Cronbach's alpha. Results: The Cronbach alpha coefficient for FACIT-F scale in our study was found to be 0.74. Kendall's coefficient of concordance was estimated to be 0.080. The correlation between Eastern Cooperative Oncology Group (ECOG) performance status and mean score of FACIT-F was studied, Pearson correlation coefficient was estimated to be 0.271 (P = 0.009). Conclusions: FACIT-F is a brief, simple, easy to administer and patient friendly tool to measure the fatigue in last 7 days. CRF should be given adequate attention from the beginning of the treatment to improve the quality of life of cancer patients.

Abstract
Background: Bone metastasis is a usual cause of pain in advanced cancer. Conventional radiation schedules require larger hospital stay and thus are not suitable for patients with poor general condition. This prospective observational study aims to compare the pain-relieving efficacy of different radiation fractionation schedules, i.e., 8 Gy administered in a single fraction versus 30 Gy administered in 10 fractions. Materials and Methods: Two hundred and fifty consecutive patients of bone metastasis were evaluated for the study, with 63 patients being excluded due to non-fulfillment of the inclusion criteria. The response to radiotherapy leading to pain relief as per the Visual Analog Scale was recorded at the end of treatment, 8 days, 15 days and 1 month during the follow-up visits. Results: Sixty-two percent of the patients received a single fraction while the remaining received 10 fractions. In the 10-fraction group, overall response was present in 60% of the patients. Stable pain was present in 23% of the patients while 9% patients had progressive pain. At 1 month of completion of treatment, 9% patients were lost to follow-up. In the single-fraction arm, overall response was seen in 58%, stable pain in 27% and progressive pain in 7% of the patients. Six percent of the patients were lost to follow-up. Conclusions: Single-fraction treatment for bony metastasis is as effective as multiple fractions to relieve bony pain and provides treatment convenience to both the patient and the caregiver.

Abstract
Background: Cisplatin is widely used as radio sensitizer in head and neck cancer (HNC) and carcinoma cervix (CaCx). This study aims to see comparative nephrotoxicity of cisplatin in HNC and in CaCx without obstructive uropathy treated by concurrent chemoradiotherapy (CCRT). Materials and Methods: Fifty patients of HNC and 50 patients of CaCx stage II/III without obstructive uropathy were included in this study. Cisplatin 50 mg intravenous weekly was given before EBRT with adequate hydration and premedication in both groups. Before chemotherapy; blood urea, serum creatinine, and glomerular filtration rate (GFR) were measured. GFR was measured using 99mTc diethylene triamine pentacaetic acid (DTPA) renogram study. Results: At the end of 4th week, blood urea level 41-45 mg% was in 40 and 4% in HNC and CaCx, respectively (P = 0.018). At the end of 3rd and 4th week, blood urea level >45 mg% was 10 and 6% in HNC cases, respectively. At the end of 4th week, serum creatinine level 1.1-1.5 mg% was 50 and 8% in HNC and CaCx, respectively (P = 0.047). Serum creatinine level >1.5 mg% was 6, 8, and 22% in HNC at the end of 2nd, 3rd, and 4th week, respectively. GFR <80 ml/min at the end of 4th week was 14% in HNC and only 2% in CaCx. GFR <100ml/min was significant at the end of 4th week (P = 0.04). Univariate analysis showed significant relation between reduced oral fluid intake and reduced GFR (P < 0.001). Conclusion: In HNC, during concurrent chemoradiation, as the 3rd-4th week is reached, oral mucosal reactions increase and affect oral intake which further add to the cisplatin-induced nephrotoxicity. In CaCx without obstructive uropathy, renal function impairment is less severe as oral intake of water and liquid is not much impaired.

Abstract
Background: After 4 months of the establishment of palliative care center (PCC) in our institute, we present an audit of the sociodemographic parameters of admitted patients. Such an audit can help to recognize the lacuna in the management and thus help to identify the specific requirements of cancer patients that might be overlooked in a busy cancer center. Materials and Methods: A total of 234 patients were admitted in our PCC since its inception in October 2013. The study design was retrospective, collecting the data from the medical records of the patients. The descriptive statistics of all these data were calculated in terms of frequencies and percentage of categorical variables. Results: Out of 234 patients admitted in PCC, 156 (66%) were male. The median age of the patients was 54 years. A total of 44% patients had primary malignancy of head and neck, 14% of cervical, 17% of lung cancer, 6% of breast, and 5% of colon, respectively. Metastatic disease was present in 76% of the patients admitted in the PCC. Liver was the most common (46%) metastatic site. Total 13 symptoms were identified with mean number of symptoms per patient at admission in PCC being 5.17. Conclusions: Palliative care services are an indispensable part of a tertiary regional cancer care center. The oncologists should be made aware of the requirement of better relief of pain and other distressing symptoms to provide better quality of life to the patients suffering from advanced cancer.

Abstract
Histiocytic sarcoma is a malignant proliferation of cells showing morphological and immunophenotypic features of mature tissue histiocytes. Most of the cases in the literature have reported CD68 positivity. We report a case of histiocytic sarcoma whose presentation mimicked a metastatic breast cancer. A 40-year-female patient presented with a 13 × 11 cm left axillary mass in close proximity to the left breast. Tru-cut biopsy from the lesion suggested the diagnosis of a lymphoid neoplasm. Complete excision of the axillary mass was done. On simple microscopy, numerous mature small lymphocytes were seen dispersed in the follicles. Immunohistochemistry revealed CD31- and CD163-positive cells, which stained negative for CD68, CD1a, cytokeratin and S100; thus, confirming the diagnosis of histiocytic sarcoma.

Double primary malignancies: a clinical & pathological analysis report from a regional cancer institute in India. IRANIAN JOURNAL OF CANCER PREVENTION 2014; 7:66-72. [PMID: 25250152 PMCID: PMC4142942] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2013] [Accepted: 12/19/2013] [Indexed: 10/31/2022]
Abstract
BACKGROUND Patients which have diagnosed with a cancer, have a life time risk for developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. Cancer victims could survive longer due to settling treatment modalities, and then would likely develop a new metachronous malignancy.This article aims to report our observed trend of increasing, in prevalence of both synchronous and metachronous second primary malignancy, among the cancer victims, and to review the relevant literature. METHODS A hospital based retrospective gathering of prospective data, among the patients that have diagnosed with second de novo malignancy.The study has conducted over a 4 years period from 2009 to 2012. All patients that have diagnosed with a histologically proven second malignancy as per Warren and Gates criteria have included. Various details which have regarded site, age at presentation, sex, synchronous or metachronous, treatment have recorded. RESULTS Among 41 cases of multiple primary malignancies that have observed, 8 were synchronous (19.51%) and 33 were metachronous (80.49%). Out of 41 patients, 25 (60.98%) were females and 16 (39.02%) were males. The most common sites of primary tumor were head and neck cancers that have followed by gynecological cancers, breast cancer, lung cancer, esophageal cancer, and then the others. Among the second malignancy, the most common site was breast and gastrointestinal tract that have followed by lung and gynecological cancers. Out of the total number of cases with double location, 14 tumors (34.15%) have belonged to the breast, out of which 5 (12.20%) have represented first locations and 7 (17.07%) have been second locations. Both locations have belonged to the breast in 2 patients (4.9%). In 5 cases (12.20%), there were associations of breast-cervix and in 6 cases (14.63%), there were association of lung-head & neck cancers. CONCLUSION The incidence of multiple primary malignancies has not been rare at all. Screening procedures have especially been useful for the early detection of associated tumors, whereas careful monitoring of patients has treated for primary cancer, and then a good communication between patients and medical care team would certify not only an early detection for secondary tumors, but only finally & subsequently, an appropriate management.

Abstract
BACKGROUND This prospective study was conducted to evaluate and compare the efficacies of nasopharyngoscopy and CT scan in the diagnosis of local failure of external beam radiotherapy (EBRT) for nasopharyngeal carcinoma. METHODS Total 52 patients of histopathologically proven nasopharyngeal carcinoma treated with external beam radiotherapy (EBRT), were included in this study. For every patient computed tomography (CT), nasopharyngoscopy and nasopharyngeal biopsies were performed 3 months after completion of EBRT. RESULTS Three months after completion of EBRT, 9 patients (17.3%) had evident disease on histological examination of biopsies. Nasopharyngoscopy showed 77.78% sensitivity, 93.03% specificity, 70% positive predictive value and 95.24% negative predictive value in diagnosing the residual/recurrence of tumor. There was statistically significant agreement between the endoscopic findings and the histological findings (Kappa reliability coefficient=0.562, p<0.01). On the other hand, CT scan showed a 55.56% sensitivity, 39.53% specificity, 16.13% positive predictive value and 80.95% negative predictive value in diagnosing the residual tumor/recurrence. There was no statistically significant agreement between the CT scan findings and the histological findings (Kappa reliability coefficient = 0.038, p>0.05). CONCLUSION Nasopharyngoscopy should be considered the primary follow-up tool after radiotherapy of nasopharyngeal carcinoma. CT scan should be reserved for patients with histological or any symptomatic indications. Routine postnasal biopsies are not required.

Abstract
The objective of this study was to investigate the effects of indoor air pollution on respiratory function of children (aged 7-15 years). The study took place at Ashok Vihar, an urban locality in the northwest part of Delhi during the summer months of June and July 2004. The team did house visits. The questionnaire, administered at the house itself, asked about the history of smoking in the family, type of cooking fuel used, duration of cooking, ventilation and lighting at the cooking place, and other confounders. In total, 441 children (59% male, 41% female) between ages 7 and 15 years were considered for the study, and a detailed profile was collected. Clinical examination with special reference to respiratory system was done. Pulmonary function tests/peak expiratory flow rates of each child were measured. Indoor air pollutant (suspended particulate matter, SO(2), NO(2)) was measured, and the effect of these pollutants on the children's respiratory function was analyzed. The respiratory health profile suggests that children had cough, sputum production, shortness of breath, wheezing, common cold, and throat congestion. Indoor SO(2) , NO(2), and suspended particulate matter levels were high in houses where there was a family history of smoking. SO(2) level was significantly high according to occupancy per room. NO(2) and suspended particulate matter levels were significantly high in houses where children had respiratory problems. It is concluded that indoor air pollution had an association with respiratory function of children.

Abstract
The authors conducted this prospective study at the Shahdara industrial area of Delhi, India. They examined the effects of indoor and outdoor air pollutant levels on respiratory health in 394 children aged 7 to 15 years. The majority of children had a history of respiratory problems, including cough (62.7%), sputum production (24.4%), shortness of breath (32.0%), wheezing (25.6%), common cold (44.4%), and throat congestion (43.1%). The association of indoor and outdoor air pollutant levels showed that outdoor SO2 and NO2 was significantly higher than indoor SO2 and NO2 levels, whereas the mean indoor level of suspended particulate matter (SPM) was significantly higher than outdoor SPM level. Indoor SPM level also was significantly higher in homes of children with a history of respiratory illness than homes of children having no history of respiratory illness. Results suggest that both indoor and outdoor particulate exposure may be important risk factors in the development of respiratory illness in children.

Abstract
OBJECTIVE We analyzed residual renal function (RRF) in a large number of new peritoneal dialysis (PD) patients to prospectively define the time course of decline of RRF and to evaluate the risk factors assumed to be associated with faster decline. STUDY DESIGN Single-center, prospective cohort study. SETTING Home PD unit of a tertiary care University Hospital. PATIENTS The study included 242 patients starting continuous PD between January 1994 and December 1997, with a minimum follow-up of 6 months and at least three measurements of RRF. MEASUREMENT All patients had data on demographic and laboratory variables, episodes of peritonitis and the use of aminoglycoside (AG) antibiotics, temporary hemodialysis, and number of radiocontrast studies. Adequacy of PD was measured from 24-hour urine and dialysate collection and peritoneal equilibration test using standard methodology. Further data on RRF was collected every 3 to 4 months until the patient became anuric (urine volume < 100 mL/day or creatinine clearance < 1.0 mL/min) or until the end of study in December 1998. OUTCOME MEASURE The slope of the decline of residual glomerular filtration rate (GFR) (an average of renal urea and creatinine clearance) was the main outcome measure. Risk factors associated with faster decline were evaluated by a comparative analysis between patients in the highest and the lowest quartiles of the slopes of GFR, and a multivariate analysis using a stepwise option within linear regression and general linear models. RESULTS There was a gradual deterioration of residual GFR with time on PD, with 40% of patients developing anuria at a mean of 20 months after the initiation of PD. On multivariate analysis, use of a larger volume of dialysate (p = 0.0001), higher rate of peritonitis (p = 0.0005), higher use of AG (p = 0.0006), presence of diabetes mellitus (p = 0.005), larger body mass index (BMI) (p = 0.01), and no use of antihypertensive medications (p = 0.04) independently predicted the steep slope of residual GFR. Male gender, higher grades of left ventricular dysfunction, and higher 24-hour proteinuria were associated with faster decline on univariate analysis only. CONCLUSION Faster decline of residual GFR corresponds with male gender, large BMI, presence of diabetes mellitus, higher grades of congestive heart failure, and higher 24-hour proteinuria. Higher rate of peritonitis and use of AG for the treatment of peritonitis is also associated independently with faster decline of residual GFR. Whether the type of PD (CAPD vs CCPD/NIPD) is associated with faster decline of residual GFR remains speculative.

Abstract
OBJECTIVE Primarily, to determine whether peritoneal small solute clearance is related to patient and technique survival among anuric peritoneal dialysis [continuous ambulatory (CAPD) and automated peritoneal dialysis (APD)] patients. A secondary goal was to describe the ability to attain Dialysis Outcomes Quality Initiative (DOQI) targets among anuric patients on peritoneal dialysis. DESIGN Retrospective cohort study via chart reviews. SETTING Peritoneal Dialysis Unit of Toronto Hospital (Western Division). PATIENTS The study included 122 CAPD and APD patients between January 1992 and September 1997, with 24-hour urine volume less than 100 mL, or renal creatinine clearance (CCr) less than 1 mL/minute. Adequacy data were available for 115 patients. OUTCOME MEASURES Mortality and technique failure (TF). Regression analysis was used to estimate the mortality and TF rate ratios (RR) for peritoneal Kt/V urea (pKt/V) and pCCr, adjusting for age, gender, diabetes, months of follow-up prior to anuria, albumin, transport status, coronary artery disease, cardiovascular disease, and peripheral vascular disease. RESULTS Fifty seven per cent (51/89) of patients on CAPD and 81% (21/26) on APD had a weekly pKt/V > or = 2 and > or = 2.2, respectively (DOQI targets); whereas only 35% on CAPD (31/89) and 35% (9/26) on APD had a weekly pCCr > or = 60 U1.73 m2 and 66 L/1.73 m2, respectively. Median follow-up times among patients were 16.5 and 19.5 months pre- and postanuria, respectively. Patients with pKt/V > or = 1.85 experienced a strong decrease in patient mortality (RR = 0.54, p= 0.10); the effect was less pronounced for pCCr > or = 50 L/1.73 m2 (RR = 0.63, p = 0.25). No relationship was observed between pKt/V or pCCr and TF. CONCLUSION Mortality was noticeably less frequent among patients with a pKt/V > or = 1.85 compared with those with a Kt/W < 1.85 (p = 0.10). Given the magnitude of the association, the failure to observe statistical significance relates to the size of the patient cohort. Our results imply that it is, in fact, possible to achieve DOQI targets among anuric patients on peritoneal dialysis.

Abstract
We prospectively analyzed 70 consecutive patients who developed acute renal failure (ARF) in the intensive care unit (ICU) during a six year period to define prognostic factors and outcome. Age, sex, preexisting chronic diseases, systemic infections, number of organs failing during the disease course, need and mode of renal replacement therapy (RRT), and length of stay in ICU were recorded. Analysis of factors in survivors (n=7, Gp A) and nonsurvivors (n=63, Gp B) was done by univariate and multivariate analysis. The mean age of patients was 28.6 years. Forty nine (70%) patients developed ARF following surgery, whereas 21 (30%) developed ARF in a medical setting. Cardiovascular surgery (39) and pancreatic surgery (7) were important causes in the surgical group, whereas in the medical group acute pancreatitis (11) was the main causative factor. One patient had ARF only, while in the rest, other organs were also involved. In more than 80% of these patients, organ failure and sepsis were present before the onset of ARF. Fifty two (74.3%) patients required dialytic support. The overall mortality was 90%. Number of organs failing, (1.5 +/-9 in Gp A vs 3.6 +/- 8 in Gp B), presence of systemic infection (1 in Gp A vs 55 in Gp B), prolonged stay in ICU (3.7 +/- 1.1 days in Gp A vs 8.0 +/- 5.4 in Gp B) and need for RRT (2 in Gp A vs 50 in Gp B) correlated with the mortality. Using multiple logistic regression analysis, only multiple organ failure (3 or more) correlated with the mortality. We conclude that multiple organ failure is a poor prognostic factor in patients with ARF in the setting of the ICU.

Abstract
Nonspecific aortoarteritis is the commonest cause of renovascular hypertension (RVH) accounting for 87% of the patients in the present study. We compared the clinical and radiographic features and outcome in children (n = 16) and adult (n = 24) patients with aortoarteritis. Children have a shorter duration of disease and present more commonly with constitutional symptoms. All the patients were hypertensive; however, malignant hypertension and hypertensive encephalopathy were more common in children. Abdominal bruit and asymmetry of pulses were present only in 75 and 35% of the patients, respectively. Asymmetric kidney size on ultrasound was present in 15 of 24 adults, whereas 9 of 16 children had equal sized kidneys. Captopril renography had a better sensitivity for detection of RVH in children (13 of 16 in children vs. 12 of 24 in adults showing positive results). On intra-arterial digital substraction angiography, abdominal aortic involvement was invariable, whereas the thoracic aorta was involved less frequently in both age groups. Angiographic scores for the severity of vascular involvement was significantly lesser in children (6.87+/-4.8) as compared to adults (11.32+/-4.5). Thirteen of the 15 children were found suitable for revascularization, whereas 12 of 24 adults were not considered for revascularization as their kidneys were small and contributed to less than 10% of total function. Six of the adult patients underwent nephrectomy for the control of blood pressure. Results of angioplasty were also better in children than adults. We conclude that children present earlier with less severe vascular disease and respond better to revascularization, as compared to adults.

Abstract
Various factors were analyzed in 80 consecutive children under 16 years who had acute renal failure (ARF), for various prognostic factors. Overall mortality was 42.5%, with significantly higher levels seen in hemolytic uremic syndrome (68%, P < 0.05) and associated with cardiac surgery (90.9%, P < 0.01). Anuria (67.6% vs. 43.5%, P < 0.05), need for dialysis (85.3% vs. 56.5%, P < 0.05), neurological complications (50% vs. 6.3%, P < 0.01), and respiratory complications (35.2% vs. 2.1%, P < 0.01) were significantly higher in nonsurvivors than survivors. Multiple regression analysis showed the presence of neurological and respiratory complications to be poor prognostic factors.

Abstract
Eighty-six hypertensive patients with clinical suspicion of renovascular hypertension (RVH) were evaluated by captopril renal scintigraphy (CRS) and intra-arterial digital subtraction angiography (IADSA) to determine the usefulness of CRS in the diagnosis of RVH and to predict the outcome of revascularization procedures. Technetium 99m-diethlenetriaminepentaacetic acid (DTPA) renal scintigraphy was performed on 2 consecutive days before and after captopril administration. Captopril renal scintigraphy was considered positive if there were changes in the time activity curve according to the criteria specified by the American Society of Hypertension working group. Captopril renal scintigraphy data were compared with presence or absence of anatomic renal artery stenosis (RAS). Of 86 hypertensive patients investigated, 45 had RAS. Aortoarteritis was the cause of RAS in 40 (89%) patients. Revascularization was done in 25 patients, and response to revascularization was compared with that of captopril renography. Compared with IADSA, CRS showed a sensitivity of 82.8% and a specificity of 98.2%. Fourteen patients had bilateral RAS on IADSA. In these patients, CRS was suggestive of bilateral disease in seven patients, unilateral in four, and negative in three. Comparison of CRS with the results of revascularization showed a sensitivity and specificity in detecting curable RAS (RVH) of 95% and 100%, respectively (positive predictive value, 100%; negative predictive value, 85%). In conclusion, we found CRS to be useful in the diagnosis of RVH due to aortoarteritis.
