This paper summarizes the difficulties that may emerge when the same care-provider attends to private and public patients within the same or different clinical settings. First, I argue that blurring the boundaries between public and private care may start a slippery slope leading to “black” under-the-table payments for preferential patient care. Second, I question whether public hospitals that allow their doctors to attend to private patients provide an appropriate learning environment for medical students and residents. Finally, I propose a way to both maintain the advantages of private care and avoid its negative consequences: complete separation between the public and the private health care systems.

 

Background: Atypical presentation of tuberculosis (TB) during pregnancy may cause diagnostic delay and adversely influence pregnancy outcome. 

Objectives: To examine the incidence and clinical and epidemiological features of TB during pregnancy and investigate infection control measures at delivery and during the postpartum period.

Methods: We retrospectively evaluated all reported cases of TB diagnosed during pregnancy to 6 months postpartum in Israel’s Northern Health District (2002–2012). 

Results: Active TB was detected in six patients; all were negative for human immunodeficiency virus (HIV). Two patients were diagnosed in the postpartum period, and four had pulmonary involvement. The average incidence during this period (3.9 per 100,000 pregnancies) was similar to that in the general population. Five patients were at high risk of contracting TB due to either recent immigration from a high-burden country or being in contact with another individual with active TB. Patients with pleuropulmonary involvement had prolonged cough and abnormal chest X-rays, without fever. Diagnosis was delayed for 3 to 7 months from symptom onset. Investigation of the newborn to rule out intrauterine infection was conducted in only one of four relevant cases. All patients were infected with organisms susceptible to all first-line drugs, and all were cured with standard therapy.

Conclusions: There was a considerable delay in the diagnosis of TB among pregnant women, and investigation of the newborn upon delivery to rule out TB infection was routinely omitted. Effective management of TB during pregnancy and the postpartum period requires a multidisciplinary approach including an obstetrician, pediatrician, TB specialist, and public health physician.

 

Background: Several trials support the trans-radial route of percutaneous coronary intervention (PCI) since it reduces access site vascular complications and bleeding. 

Objectives: To examine the effects of trans-radial interventions (TRI) on clinical outcomes in a 'real world' cohort of patients undergoing PCI.

Methods: We analyzed 4873 consecutive patients who underwent PCI at a tertiary center and identified 373 patients who underwent TRI. Patients (radial vs. femoral) were compared using a propensity score analysis to best match between groups. Outcome parameters included total mortality, myocardial infarction (MI), repeat target vessel revascularization (TVR) rates, length of hospitalization and ∆Ht/Hb/creatinine values during hospitalization. These were evaluated at 6 months and 1 to 3 years after PCI.

Results: The rates of major adverse cardiovascular event (MACE) and its constituents were similar in the trans-radial vs. trans-femoral groups at all time intervals: 6.7% vs. 5.5% at 6 months, 10.3% vs. 10% at 1 year, 15.7% vs. 15% at 2 years, 15.7% vs. 16% at 3 years, respectively (P = 0.6). The length of hospitalization was shorter in the TRI group (2.87 days ± 2.04 vs. 3.3 days ± 3.12, P = 0.023). We did not find significant differences between the groups in the mean ∆Ht/Hb/creatinine values during the hospitalization course.

Conclusions: In a 'real-world' setting of PCI, the TRI route of PCI is as safe and efficient as the femoral approach. TRI is associated with shorter duration of hospitalization.

 

Abstract

Background: A single self-rated health (SRH) assessment is associated with clinical outcome and mortality, but the biological process linking SRH with immune status remains incompletely understood.

Objectives: To examine the association between SRH and inflammation in apparently healthy individuals.

Methods: Our analysis included 13,773 apparently healthy individuals attending the Tel Aviv Sourasky Medical Center for periodic health examinations. Estimated marginal means of the inflammation-sensitive biomarkers [i.e., highly sensitive C-reactive protein (hs-CRP) and fibrinogen] for the different SRH groups were calculated and adjusted for multiple potential confounders including risk factors, health behavior, socioeconomic status, and coexistent depression.

Results: The group with the lowest SRH had a significantly higher atherothrombotic profile and significantly higher concentrations of all inflammation-sensitive biomarkers in both genders. Hs-CRP was found to differ significantly between SRH groups in both genders even after gradual adjustments for all potential confounders. Fibrinogen differs significantly according to SRH in males only, with low absolute value differences.

Conclusions: A valid association exists for apparently healthy individuals of both genders between inflammation-sensitive biomarker levels and SRH categories, especially when comparing levels of hs-CRP. Our findings underscore the importance of assessing SRH and treating it like other markers of poor health.

Abstract

Background: Iatrogenic ureteral injury may be seen following abdominopelvic surgeries. While ureteral injuries identified during surgery should be immediately and surgically repaired, those that are postoperatively diagnosed may be treated non-surgically by draining the ipsilateral kidney. Data regarding the outcome of this approach are still missing.

Objectives: To evaluate the success rates of non-surgical management of ureteral injuries diagnosed following abdominopelvic surgeries.

Methods: We retrospectively reviewed the files of all patients treated for iatrogenic ureteral injuries diagnosed following abdominopelvic surgeries. Patients' ipsilateral kidney was percutaneously drained following diagnosis of injury by either nephrostomy tube (NT)/nephro-ureteral stent (NUS) or double-J stent (DJS) inserted retrogradely. The tube was left in place until a pyelogram confirmed healing or a conservative approach was abandoned due to failure.

Results: Twenty-nine patients were identified as having ureteral injury following abdominopelvic surgery. Median time from injury to renal drainage was 9 days, interquartile range (IQR) 4–17 days. Seven cases (24%) had surgical repair. Among the other 22 patients, in 2 oncology patients the conservative approach was maintained although renal drainage failed to resolve the injury. In the remaining 20, median drainage length was 60 days (IQR 43.5–85). Calculated overall success rates following renal drainage was 69% (18/29), and with NS approached 78.5%.

Conclusions: Ureteral injuries diagnosed following abdominopelvic surgeries can be treated conservatively. Ipsilateral renal drainage should be the first line of treatment before surgical repair, and NUS may be the preferred drainage to obtain spontaneous ureteral healing. 

Abstract

Background: Laryngeal cleft (LC) is a rare congenital anomaly manifesting in a variety of symptoms including swallowing disorders and aspirations, dyspnea, stridor and hoarseness. The mild forms (types I-II) may be underdiagnosed, leading to protracted symptomatology and morbidity. 

Objectives: To evaluate the diagnostic process, clinical course, management and outcome in children with type I-II laryngeal clefts.

Methods: We conducted a retrospective case analysis for the years 2005–2012 in a tertiary referral center.

Results: Seven children were reviewed: five boys and two girls, aged from birth to 5 years. The most common presenting symptoms were cough, aspirations and pneumonia. Evaluation procedures included fiber-optic laryngoscopy (FOL), direct laryngoscopy (DL) and videofluoroscopy. Other pathologies were seen in three children. Six children underwent successful endoscopic surgery and one child was treated conservatively. The postoperative clinical course was uneventful in most of the cases.

Conclusions: Types I-II LC should be considered in the differential diagnosis of children presenting with protracted cough and aspirations. DL is crucial for establishing the diagnosis. Endoscopic surgery is safe and should be applied promptly when conservative measures fail. 

Abstract

Background: Diabetes mellitus-related lower extremity amputation is a major complication severely affecting patient survival and quality of life.

Objectives: To analyze epidemiological and clinical trends in the incidence and survival of lower extremity amputations among diabetes patients.

Methods: We conducted a retrospective observational cohort study of 565 consecutive diabetes patients who underwent their first non-traumatic lower extremity amputation between January 2002 and December 2009.

Results: Major amputations were performed in 316 (55.9%) patients: 142 above the knee (25.1%) and 174 below (30.8%); 249 (44.1%) had a minor amputation. The incidence rates of amputations decreased from 2.9 to 2.1 per 1000 diabetes patients. Kaplan-Meier survival analysis showed that first year mortality rates were lower among patients with minor amputations (31.7% vs. 39.6%, P = 0.569). First year mortality rates following below-knee amputation were somewhat lower than above-knee amputation (33.1 vs.45.1%, respectively). Cox regression model of survival at 1 year after the procedure found that age (HR 1.06 per year, 95% CI 1.04–1.07, P < 0.001), above-knee amputation (HR 1.36, 95% CI 1.01–1.83, P = 0.045) and ischemic heart disease (HR 1.68, 95% CI 1.26–2.24, P < 0.001) significantly increased one year mortality risk.

Conclusions: In this population-based study the incidence rate of non-traumatic amputations in diabetes patients between January 2002 and December 2009 decreased slightly. However, one year mortality rates after the surgery did not decline and remained high, stressing the need for a multidisciplinary effort to prevent amputations in diabetes patients.

Abstract

Background: Renal hemangiomas are rare benign tumors seldom distinguished from malignant tumors preoperatively.

Objectives: To describe the Memorial Sloan-Kettering Cancer Center (MSKCC) experience with diagnosing and treating renal hemangiomas, and to explore possible clinical and radiologic features that can aid in diagnosing renal hemangiomas preoperatively.

Methods: Patients with renal hemangiomas treated at MSKCC were identified in our prospectively collected renal tumor database. Descriptive statistics were used to describe the patient characteristics and the tumor characteristics. All available preoperative imaging studies were reviewed to assess common findings and explore possible characteristics distinguishing benign hemangiomas from malignant renal tumors preoperatively.

Results: Of 6341 patients in our database 15 were identified. Eleven (73%) were males, median age at diagnosis was 53.3 years, and the affected side was evenly distributed. All but two patients were treated surgically. The mean decrease in estimated glomerular filtration rate (eGFR) after surgery was 36.3%; one patient had an abnormal presurgical eGFR and only two patients had a normal eGFR after surgery. We could not identify radiographic features that would make preoperative diagnosis certain, but we did identify features characteristic of hepatic hemangiomas that were also present in some of the renal hemangiomas.

Conclusions: Most renal hemangiomas cannot be distinguished from other common renal cortical tumors preoperatively. In select cases a renal biopsy can identify this benign lesion and the deleterious effects of extirpative surgery can be avoided.

Abstract

Background: Heart rate variability (HRV) analysis has been shown to be a predictor of sudden cardiac death and all-cause mortality in patients with cardiac disease.

Objectives: To examine whether newer HRV analysis algorithms, as used by the HeartTrends device, are superior to exercise stress testing (EST) for the detection of myocardial ischemia in patients without known coronary artery disease (CAD).

Methods: We present pilot data of the first 100 subjects enrolled in a clinical trial designed to evaluate the yield of short-term (1 hour) HRV testing for the detection of myocardial ischemia. The study population comprised subjects without known CAD referred to a tertiary medical center for EST with single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). All patients underwent a 1 hour electrocardiographic acquisition for HRV analysis with a HeartTrends device prior to EST with MPI. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV, respectively) were calculated for EST and HRV analysis, using MPI as the gold standard for the non-invasive detection of myocardial ischemia.

Results: In this cohort 15% had a pathologic MPI result. HRV analysis showed superior sensitivity (85%), PPV (50%) and NPV (97%) as compared to standard EST (53%, 42%, 90%, respectively), while the specificity of the two tests was similar (86% and 85%, respectively). The close agreement between HRV and MPI was even more pronounced among patients > 65 years of age.

Conclusions: Our pilot data suggest that the diagnostic yield of the novel HeartTrends HRV algorithm is superior to conventional EST for the non-invasive detection of myocardial ischemia.
