Background: Patients with type 1 diabetes (T1D) are exempt from conscript military service, but some volunteer for national service. 

Objectives: To evaluate the effect of national service (military or civil) on metabolic control and incidence of acute diabetes complications in young adults with T1D. 

Methods: Clinical and laboratory data of 145 T1D patients were retrieved from medical records. The cohort comprised 76 patients volunteering for national service and 69 non-volunteers. Outcome measures were HbA1c, body mass index-standard deviation scores (BMI-SDS), insulin dosage, and occurrence of severe hypoglycemia or diabetic ketoacidosis (DKA). 

Results: Metabolic control was similar in volunteers and non-volunteers: mean HbA1c at various time points was: 7.83 ± 1.52% vs. 8.07% ± 1.63 one year before enlistment age, 7.89 ± 1.36% vs. 7.93 ± 1.42% at enlistment age, 7.81 ± 1.28% vs. 8.00 ± 1.22% one year thereafter, 7.68 ± 0.88% vs. 7.82 ± 1.33% two years thereafter, and 7.62 ± 0.80% vs. 7.79 ± 1.19% three years thereafter. There were no significant changes in HbA1c from baseline throughout follow-up. BMI and insulin requirements were similar and remained unchanged in volunteers and controls: mean BMI-SDS one year before enlistment age was 0.23 ± 0.83 vs. 0.29 ± 0.95, at enlistment age 0.19 ± 0.87 vs. 0.25 ± 0.98, one year thereafter 0.25 ± 0.82 vs. 0.20 ± 0.96, two years thereafter 0.10 ± 0.86 vs. 0.15 ± 0.94, and three years thereafter 0.20 ± 0.87 vs. 0.16 ± 0.96. Mean insulin dose in U/kg/day one year before enlistment age was 0.90 ± 0.23 vs. 0.90 ± 0.37, at enlistment age 0.90 ± 0.28 vs. 0.93 ± 0.33, one year thereafter 0.86 ± 0.24 vs. 0.95 ± 0.33, two years thereafter 0.86 ± 0.21 vs. 0.86 ± 0.29, and three years thereafter 0.87 ± 0.23 vs. 0.86 ± 0.28. There were no episodes of severe hypoglycemia or DKA in either group. 

Conclusions: Our data indicate that during voluntary national service young adults with T1D maintain metabolic control similar to that of non-volunteers. 

 

Background: The role of autoimmune factors in the etiology of coronary artery disease (CAD) was suggested in numerous studies but has not been definitively determined.

Objectives: To assess the possible influence of antiphospholipid and antinuclear antibodies on atherosclerosis development in young patients after myocardial revascularization procedures.

Methods: The study group included 39 patients younger than 45 years with coronary artery disease (CAD) who underwent myocardial revascularization. Serum levels of antiphospholipid (aPL), antinuclear (ANA) and antineutrophil cytoplasmatic (ANCA) antibodies were tested within 1 month after the procedure.

Results: All three types of aPL were significantly higher in CAD patients when compared to healthy controls: anti-β2-glycoprotein I (aβ2GPI), both immunoglobulin (Ig)G and IgM classes (median 4.10 SGU, range 3.45–21.63 vs. 0.76, 0.12–6.01, P < 0.001, and 2.82 SGU, 1.44–11.70 vs. 1.08, 0.44–3.64, P < 0.001, respectively); anticardiolipin antibodies (aCL) both IgG and IgM classes (3.13 GPL, 1.32–14.03 vs. 2.42, 0.96–18.45, P = 0.0037, and 6.94 MPL, 1.90–26.40 vs. 4.32, 1.9–28.73, P < 0.008, respectively); and lupus anticoagulant (LA) (27.7% vs. 0%, P = 0.005). ANA were elevated in one patient and ANCA in 23 (60%). The levels of aPL did not correlate with the presence of a clot in a coronary vessel detected during angiography or with exacerbation of coronary artery atherosclerosis.

Conclusions: In young patients with CAD who underwent myocardial revascularization the levels of aPL were significantly higher than in young healthy subjects. Thus, besides the classic risk factors for CAD, autoimmunity may play an important role in atherosclerotic plaque formation and progression.

Background: Hypernatremic dehydration is a common and potentially life-threatening condition in children. There is currently no consensus as to the optimal strategy for fluid management. Objectives: To describe the relationship between the type, route and rate of fluids administered and the rate of decline in serum sodium (Na+) concentration. 

Methods: We reviewed the medical records of all children under the age of 2 years who were hospitalized with hypernatremic dehydration (serum Na+ ≥ 155 mEq/L) in Shaare Zedek Medical Center during the period 2001–2010. Collected data of 62 subjects included initial and subsequent serum Na+ levels, and rate and Na+ concentration of all intravenous and oral fluids administered until the serum Na+ reached ≤ 150 mEq/L.

Results: Median initial serum Na+ was 159.5 mEq/L (IQR 157–163, maximal value 170). The median rate of decline in serum Na+ until serum Na+ reached 150 mEq/L was 0.65 mEq/L/hr (IQR 0.45–0.95). Forty-two children received hypotonic oral fluids which accounted for approximately one-quarter of all fluids they received. There was no significant difference in the rate of decline in serum Na+ between those who consumed oral fluids and those who did not. Neither was there a correlation between the rate of IV fluids, receipt of oral fluids or the degree of dehydration, with the rate of decline in serum Na+. No child experienced an apparent short-term adverse outcome. 

Conclusions: A cumulative rate of 5.9 ml/kg/hr of IV fluid administration may reduce the serum Na+ to an acceptable rate (0.65 mEq/L/hr). Fluid therapy comprising up to 25% hypotonic oral fluids and 75% IV fluids high in Na+ concentration was not associated with any short-term adverse outcome in our patient population. 

 

Background: The surgical treatment of hip fractures remains controversial especially when considering age. 

Objectives: To investigate the long-term functional outcomes of displaced subcapital hip fractures that were reduced and surgically fixed using parallel cannulated screws in patients aged 60 years and younger. 

Methods: During the period 1996–2005, 27 patients under age 60 with displaced subcapital hip fractures classified as Garden III or IV were treated with fracture reduction and surgical internal fixation using cannulated screws. Patient outcomes were assessed using the Harris Hip Score (HHS) and physical examination.

Results: During a follow-up period of 8–17 years 4 of the 27 patients (14.8%) developed non-union/femoral head avascular necrosis and had undergone hip arthroplasty. All reoperations were performed within the first year after fracture fixation, all in the 50–60 year old age group. The revision rate among patients 50–60 years old was significantly higher than that of patients 50 years and younger (40% vs. 0%, P = 0.037). Mean HHS was higher for patients not requiring revision surgery (85.4) than for patients with revision surgery (75.5), but this difference was not significant.

Conclusions: Internal fixation using fracture reduction and cannulated screw fixation is a successful treatment modality for displaced subcapital hip fractures in patients younger than 50 years old. Patients aged 50–60 years may have a higher risk of avascular necrosis or non-union and require arthroplasty, often within the first year after fracture fixation. The long-term outcome following these fractures is good when excluding patients who had early complications.

 

Objectives: To investigate whether young patients, i.e., under age 50, complain of symptoms for longer than older patients until the diagnosis of colon cancer is established.

Methods: In this retrospective cohort study, patients were divided into two groups: < 50 years old (group 1) and ≥ 50 (group 2). All had undergone surgery for left or right colon cancer during the 1 year period January 2000 through December 2009 at one medical center. Rectal and sigmoid cancers were excluded. Data collected included age, gender, quantity and quality of complaints, duration of complaints, in-hospital versus community diagnosis, pathological staging, the side of colon involved, and overall mortality. The main aim was the quality and duration of complaints. Secondary outcomes were the pathological stage at presentation and the mortality rate.

Results: The study group comprised 236 patients: 31 (13.1%) were < 50 years old and 205 (86.9%) were ≥ 50 years. No significant difference was found in the quantity and quality of complaints between the two groups. Patients in group 1 (< 50 years) complained for a longer period, 5.3 vs. 2.4 months (P = 0.002). More younger patients were diagnosed with stage IV disease (38.7% vs. 21.5%, P = 0.035) and fewer had stage I disease (3.2% vs. 15.6%, P = 0.06); the mortality rates were similar (41.9% vs. 39%). Applying a stepwise logistic regression model, the duration of complaints was found to be an independent predictor of mortality (P = 0.03, OR 1.6, 95% CI 1–3.6), independently of age (P = 0.003) and stage (P < 0.001).

Conclusions: Younger patients are more often diagnosed with colon cancer later, at a more advanced stage. Alertness to patients’ complaints, together with evaluation regardless of age but according to symptoms and clinical presentation are crucial. Large-scale population-based studies are needed to confirm this trend.
