Morphometric analysis of foramen ovale, foramen spinosum, and foramen rotundum of human skull using computed tomography scan: a cross-sectional study.

There is limited literature of objective assessments of foramina of skull base using computed tomography (CT) scan. This study was carried out to analyze the dimensions of foramen ovale (FO), foramen spinosum (FS), and foramen rotundum (FR) using CT scan imaging of the human skull and their associations with sex, age, and laterality of the body. Materials and methods: A cross-sectional study was carried out in the Department of Radiodiagnosis and Imaging at BP Koirala Institute of Health Sciences (BPKIHS), Nepal using a purposive sampling method. We included 96 adult patients (≥18 years) who underwent CT scan of the head for any clinical indications. All those participants below 18 years, inadequate visualization or erosions of skull base foramina, and/or not consenting were excluded. Appropriate statistical calculations were done using the statistical package for social sciences (SPSS), version 21. The P-value of less than 0.05 was considered statistically significant. Results: The mean length, width, and area of FO was 7.79±1.10 mm, 3.68±0.64 mm, and 22.80±6.18 mm2, respectively. The mean length, width, and area of FS was 2.38±0.36 mm, 1.94±0.30 mm, and 3.69±0.95 mm2, respectively. Similarly, the mean height, width, and area of FR was 2.41±0.49 mm, 2.40±0.55 mm, and 4.58±1.49 mm2, respectively. The male participants had statistically significant higher mean dimensions of FO and FS (P<0.05) than the female participants. There were statistically insignificant correlations of dimensions of these foramina with age and between the left and right side of each foraminal dimensions (P>0.05). Conclusions: The sex-based difference in dimensions of FO and FS should be clinically considered in evaluating the pathology of these foramina. However, further studies using objective assessment of foraminal dimensions are required to draw obvious inferences.

Delayed graft function: current status and future directions.

PURPOSE OF REVIEW: Delayed graft function is a common early posttransplant event predictive of adverse outcomes including hospital readmission, impaired long-term graft function, and decreased graft and patient survival. The purpose of this review is to summarize recent literature describing delayed graft function in hopes of better understanding and managing this condition. RECENT FINDINGS: Recent research efforts have been garnered towards risk factor modification, prevention, and earlier detection of delayed graft function. In this review, we aim to summarize current innovative approaches and future directions. SUMMARY: Delayed graft function portends worse graft and patient outcomes. Continued research to prevent, and detect early perturbations in allograft function, and more optimally manage this disease will hopefully improve graft function, along with graft/patient survival.

Study, Design, and Rationale of Noncommunicable Diseases in Nepal (NCD Nepal) Study: A Community-Based Prospective Epidemiological and Implementation Study in Rural Nepal.

BACKGROUND: Noncommunicable diseases (NCDs) are the leading causes of deaths globally. Currently, there are limited high-quality data on the epidemiology and usefulness of community-based screening and treatment of NCDs in low-to-middle-income countries (LMIC), like Nepal. We describe the protocol of a community-based, longitudinal epidemiological study of screening and management of NCDs in rural Nepal. METHODS: We organize monthly mobile health clinics to screen NCDs among 40- to 75-year-old residents from municipal subdivision wards 3, 4, 6, and 7 of Ghorahi submetropolitan city, Dang, Nepal (approximately 406 km west of the capital, Kathmandu). We estimate a total of 7052 eligible participants. After obtaining informed consent, trained personnel will collect sociodemographic and lifestyle data, medical, medication, and family history using validated questionnaires, plus anthropometric measures and capillary glucose levels. We will screen for hypertension, diabetes, obesity, dyslipidemia, tobacco and alcohol use, self-reported physical activity, dietary habits, cardiovascular disease, stroke, chronic lung disease, cancer, and chronic kidney disease. We will also check hemoglobin A1C, lipid panel, serum creatinine, sodium, potassium, urine dipstick, and urine albumin-to-creatinine ratio in high-risk participants. We will offer lifestyle counseling, pharmacotherapy or refer to higher level care, where appropriate; routinely follow participants with NCDs for continuity of care; and follow individuals without NCDs but with elevated glucose, prehypertension or other risk factors every year, and those without risk factors every 2 years. We will monitor participants in the community to reduce attrition and to track all-cause and disease-specific mortality. DISCUSSION: Understanding the community burden of NCDs in resource-limited setting and testing effectiveness of community-based screening and management of NCDs will provide insights to develop national policy to address NCD burden in LMIC like Nepal.

Rheumatoid subacromial-subdeltoid bursitis with rice bodies: A case report.

Subacromial-subdeltoid bursitis of a shoulder with rice bodies is relatively uncommon. The understanding of the pathogenesis of rice body formation is yet approximate only but some clinical conditions like rheumatoid arthritis, tuberculous arthritis, seronegative inflammatory arthritis, juvenile rheumatoid arthritis and osteoarthritis are related to it. We describe a case of a 44 years old female with subacromial-subdeltoid bursitis of her right shoulder with numerous rice bodies' formation as a presenting feature of rheumatoid arthritis. She underwent subacromial and subdeltoid bursectomy with the removal of rice bodies and had immediate improvement of symptoms.

Outcomes of Adult Intestinal Transplant Recipients Requiring Dialysis and Renal Transplantation.

BACKGROUND: Data on dialysis and renal transplantation (RT) after intestinal transplantation (IT) are sparse. Whether changes in immunosuppression and surgical techniques have modified these outcomes is unknown. METHODS: Two hundred eighty-eight adult intestinal transplants performed between 1990 and 2014 at the University of Pittsburgh were analyzed for incidence, risk factors and outcomes after dialysis and RT. Cohort was divided into 3 eras based on immunosuppression and surgical technique (1990-1994, 1995-2001, and 2001-2014). Receiving RT, or dialysis for 90 days or longer was considered as end-stage renal disease (ESRD). RESULTS: During a median follow-up of 5.7 years, 71 (24.7%) patients required dialysis, 38 (13.2%) required long-term dialysis and 17 (6%) received RT after IT. One-, 3-, and 5-year ESRD risk was 2%, 7%, and 14%, respectively. No significant era-based differences were noted. Higher baseline creatinine (hazard ratio [HR], 3.40 per unit increase, P < 0.01) and use of liver containing grafts (HR, 2.01; P = 0.04) had an increased ESRD risk. Median patient survival after dialysis initiation was 6 months, with a 3-year survival of 21%. Any dialysis (HR, 12.74; 95% CI 8.46-19.20; P < 0.01) and ESRD (HR, 9.53; 95% CI, 5.87-15.49; P < 0.01) had higher mortality after adjusting for covariates. For renal after IT, 1- and 3-year kidney and patient survivals were 70% and 49%, respectively. All graft losses were from death with a functioning graft, primarily related to infectious complications (55%). CONCLUSIONS: In intestinal transplant recipients, renal failure requiring dialysis or RT is high and is associated with increased mortality. Additionally, the outcomes for kidney after IT are suboptimal due to death with a functioning graft.

Cytomegalovirus infection in high-risk kidney transplant recipients receiving thymoglobulin induction-a single-center experience.

BACKGROUND: The burden of cytomegalovirus infection in CMV high-risk (donor positive to recipient negative) kidney transplant recipients getting thymoglobulin induction and six months of valganciclovir is not well characterized. Additionally, the role of post-prophylaxis surveillance remains unclear. METHODS: One-year observational study of forty-eight high-risk CMV kidney transplant recipients transplanted under thymoglobulin between January 2013 and July 2014. All received valganciclovir for six months, followed by monthly CMV PCR for three months. RESULTS: CMV infection defined as viremia with or without symptoms occurred in 40% (19/48). Of these, 47% (9/19) occurred during prophylaxis, 32% (6/19) during surveillance and 21% (4/19) during post-surveillance period (9-12 months). Among breakthrough infections, suboptimal valganciclovir dosing was present in 55% (5/9). With routine surveillance, there was a trend toward lower CMV-related hospitalization (17% vs 56% and 75% during prophylaxis and post-surveillance, respectively [P=.23]) and lower mean peak viral loads (19 432 copies/mL vs 97 925 copies/mL and 536 021 copies/mL during prophylaxis and post-surveillance, respectively [P=.07]). CONCLUSION: CMV infection remains a significant problem with thymoglobulin induction despite six months of valganciclovir. Suboptimal valganciclovir dosing was common among breakthrough infections. Monthly surveillance post-prophylaxis appears to detect early CMV infection with lower degree of viremias requiring fewer hospitalizations.

Geriatric Issues in Older Dialysis Patients.

Geriatric syndrome is common among older patients on dialysis. Basic knowledge about its prevalence and management is crucial for nephrologists to provide standard patient care. In busy clinical settings, up-to-date and holistic medical care can be delivered to elderly dialysis patients by collaboration of nephrology and geriatrics teams, or in part by training nephrology fellows the basics of geriatrics.

Management of Femoral Shaft Fracture in Klippel-Trenaunay Syndrome with External Fixator.

Klippel-Trenaunay syndrome (KTS) is a rare complex malformation characterized by the clinical triad of capillary malformations, soft tissue and bone hypertrophy, and venous/lymphatic malformation. Fractures of long bones in such cases are challenging to treat. A 12-year-old female with this syndrome presented with femoral shaft fracture of right thigh. She was initially kept on skeletal traction for two weeks and then she underwent closed reduction and immobilization with external fixator with uneventful intraoperative and postoperative period. Fracture united at four and half months.

Recurrent Mixed Cryoglobulinemia (MCS): A Case Report and Literature Review.

We report a case of recurrent mixed type II cryoglobulinemia with difficult diagnosis and treatment dilemma and uncertain prognosis in view of limited studies. A 60-year-old male with history of essential mixed cryoglobulinemia 12 years ago treated successfully with six months of cyclophosphamide and prednisone presented with bilateral lower extremity pupuric rash and swelling. He was found to have proteinuria, hematuria, RBC casts, low serum complement levels, and acute kidney injury (AKI). Initial therapy with methylprednisone and oral cyclophosphamide was ineffective (patient developed respiratory failure due to alveolar hemorrhage). Additional labs revealed positive type II cryoglobulins, high free Kappa/Lambda, UPEP with minimal urine protein, SPEP with marked hypogammaglobulinemia, and negative tests for HIV, HCV, ANA, and ANCA. More aggressive therapy with daily plasmapheresis and rituximab was instituted with very good clinical response. He achieved clinical remission but developed another flare 8 months later. Kidney biopsy showed membranoproliferatve glomerulonephritis with cryoglobulin deposits. Flow cytometry and biopsy of bone marrow was consistent with lymphoplasmacytic lymphoma. His diagnosis was eventually confirmed and responded clinically to another course of rituximab and plasmapheresis, but prognosis is yet to be seen.

Spontaneous coronary dissection in polycystic kidney disease.

We report a case of a 46-year-old woman with hypertension and autosomal dominant polycystic kidney disease who presented with chest pain and was found to have spontaneous coronary artery dissection (SCAD) on diagnostic catheterization. We review the pathogenesis, management and prognosis of SCAD. We conclude that in patients with polycystic kidney disease who present with angina pectoris and positive cardiac biomarkers, coronary artery dissection should be considered.
