Objectives: To define the length of time required to rehabilitate and discharge these patients, and to identify predictors of a prolonged or failed discharge process.

Methods: We conducted a retrospective chart review of patients admitted to the Respiratory Rehabilitation Unit at Alyn Hospital, Jerusalem, over a 4 year period.

Results: Of the 48 patients identified, 31 (64.7%) were eventually discharged, 13 (27.1%) remained hospitalized long-term, and 4 (8.3%) died during their hospitalization. The median length of hospitalization was 10 months: 6 months for purposes of rehabilitation therapy, and 4 months thereafter to resolve the logistics of discharge. Specific family characteristics – an unemployed father (odds ratio = 4.6, P = 0.02) and an additional family member with a disability (OR[1] = 5.8, P = 0.03) – as well as ongoing mechanical ventilation at the time of discharge (OR = 5.5, P < 0.01) were found to positively correlate with a prolonged or failed discharge process.

Conclusions:  Hospitalization in a pediatric respiratory rehabilitation unit may be prolonged for both medical and non-medical reasons, with the process of discharge home being particularly difficult in certain subsets of patients. A proactive discharge policy by hospitals, improved community support services, and legislation defining the rights of home-ventilated children may facilitate more efficient discharge home of these patients.

Background: Physicians in the community work on a tight and often pressured schedule; verbal and non-verbal techniques to terminate the patient-physician encounter are therefore necessary.

Objectives: To characterize ways of terminating the encounter.

Methods: Using a structured questionnaire we observed seven family physicians and nine consultants and recorded patient-physician encounters to assess techniques for terminating the encounter.

Results: In all, 320 encounters were recorded, 179 (55.9%) by consultants and 141 (44.1%) by family physicians. The mean duration of the encounters was 9.02 ± 5.34 minutes. The mean duration of encounters with family physicians was longer than consultants (10.39 vs. 7.93 minutes, P < 0.001). In most cases the encounter ended with the patient receiving printed documentation from the physician (no difference between family physicians and consultants). Consultants were more likely to end the encounter with a positive concluding remark such as “feel good” or “be well” (P < 0.01). There was no single occasion where termination of the encounter was initiated by the patient.

Conclusions: Giving a printed document to the patient appears to be perceived by both patients and physicians as an accepted way to end an encounter. Another good way to end the encounter is a positive greeting such as “feel good” or “be well.”
 

The pulmonary microbiology is a dominant element in cystic fibrosis and the main cause of death. Contemporary consensus accords an exclusive role in this to a single microorganism, Pseudomonas aeruginosa. The evidence convincingly shows that the microbiology consists of a multiplicity of species living in perpetual interaction and in a variety of forms – planktonic, sessile, anaerobic – and in organized communities as microcosms, biofilms and ecosystem. This compound microbiology, the essence of the pulmonary disease, is of necessity exposed to constant influence both from without (the air) and within (via the blood), leading to a perpetual state of flux with consequent impact on the clinical course. It is perhaps significant that to date, most or all microbiologic studies were probably conducted, classically, with inert instruments (glass? plastic?), whereas in real life the CF[1] microbiology lives in “test-tubes” of live mucosa with which it maintains a permanent “cross-talk.” The difference to microbial life between these two media may well be very important. It therefore justifies study and may be far-reaching in its effect. There is persuasive argument to strive for a novel holistic view of the totality of the complex microbiology of CF, and to initiate fresh concepts, strategies and methods.

Objectives: To investigate the effect of low calcium dialysis on post-dialysis hypertension in view of an evident link between serum calcium and blood pressure in both normal renal function and chronic renal failure patients.

Methods: We evaluated 19 chronic hemodialysis patients in whom both post-dialysis hypertension and PDHCa[1] were observed. We investigated changes in serum total calcium, ionized calcium, intact parathormone levels and arterial blood pressure in response to 4 weeks low calcium dialysis as a treatment for PDHCa.

Results: When PDHT[2] patients were treated with low calcium dialysis, post-dialysis blood pressure was significantly decreased compared to pre-dialysis values (155.3 ± 9.7/82.2 ± 7.9 mmHg pre-dialysis vs. 134.1 ± 20.8/80 ± 8.6 mmHg post-dialysis, P = 0.001). Additionally, post-dialysis blood pressure was significantly lower than post-dialysis blood pressure prior to the low calcium dialysis treatment (176.1 ± 15/86 ± 10.8 mmHg post-standard dialysis, 134.1 ± 20.8/80 ± 8.6 mmHg after low calcium dialysis, P = 0.001). A decline in post-dialysis serum calcium (2.34 ± 0.2 vs. 2.86 ± 0.12 mmol/L, P = 0.04) and ionized calcium (1.17 ± 0.12 vs. 1.3 ± 0.06 mmol/L, P = 0.03) compared to pre-dialysis levels was also achieved by this treatment, with no significant changes in iPTH[3] levels.

Conclusions: These data suggest a role for low calcium dialysis in treating acute serum calcium elevation and post-dialysis hypertension in patients receiving maintenance hemodialysis.

Objectives: To describe the sociodemographic, medical and functional characteristics of people aged 80–90 and 90+ who were admitted to a sub-acute geriatric hospital and to compare the hospitalization outcomes between these subgroups.

Methods: We compared the demographic and clinical data (extracted by means of chart review) of two groups of elderly who were admitted to the Reuth Medical Center during 2001–2002: those aged 90+ and those 80–89. Among survivors, the main outcome measures at discharge were mortality rate, functional ability, and place of residence.

Results: The study included 108 patients who were admitted to different divisions of Reuth: 55 patients aged 90+ and 53 aged 80–90. The mortality rate was significantly elevated in the older age group (49.1% vs. 28.1% in the younger age group) on multivariate analysis. The most important prognostic factors for mortality were incontinence (odds ratio 3.45) and being dependent before admission (OR[1] 4.76). Among survivors an association was found between being incontinent and dependent before hospitalization, and being dependent on discharge.

Conclusions: The main prognostic factors for mortality and functional outcome in patients admitted to a non-acute geriatric hospital are incontinence and functional state prior to admission, and not age per se.

Objective: To present our algorithm of urgent and elective donor selection.

Methods: Urgent selection is expeditious and protocol‑based. Elective selection permits a comprehensive process. Both include medical, psychosocial and surgical-anatomic evaluations. Liver volumes and vascular anatomy are evaluated with computerized tomographic angiography. Informed consent is obtained after painstaking explanations. Independent institutional committees review and approve all cases.

Results: Between July 2003 and June 2004 we evaluated 43 potential live donors for 12 potential recipients (fulminant hepatic failure, n=5; chronic end-stage liver disease, n=6); primary graft non-function, n=1). Thirty-three candidates (76%) were excluded due to blood type incompatibility (n=14, 42%), incompatible anatomy (n=8, 24%) – including problematic volume distribution (n=2) or vascular anatomy (n=6) – psychosocial issues (n=4, 12%), or medical co-morbidity (n=7, 22%). Five recipients (FHF[1], n=4; chronic ESLD[2], n=1) were successfully transplanted from living donors. In the acute setting, two patients (FHF, PGNF[3]) died in the absence of an appropriate donor (cadaveric or living donor). In the elective group, one patient died of unexpected variceal bleeding and one received a cadaveric graft just before the planned living donor transplantation was performed. One candidate was transplanted overseas and two cases are scheduled. The ratio of compatibility for donation was 34% (10/29) for blood type-compatible candidates.

Conclusions: Donor selection for living donor liver transplantation is a complex, labor-intensive multidisciplinary process. Most exclusions are due to blood type incompatibility or anatomic details. Psychosocial aspects of these donations warrant special attention.

Objective: To describe the experience of our CF[1] center in the management of CF pregnant woman from 1977 to 2004.

Methods: We analyzed 27 years of records (1977–2004) of the national CF registry of all CF women who wished to conceive and became pregnant.

Results: Eight CF women (mean age 24 ± 4.5 years) who wished to conceive had 11 pregnancies and delivered 12 neonates. The pregestational results of forced expiratory volume per 1 second varied significantly among patients (59 ± 23%), yet most (10/11) stayed stable throughout the pregnancy course. Maternal deterioration in CF condition occurred in only one mother, necessitating cesarean section. In 9 of the 11 pregnancies the women were pancreatic-insufficient. Of the 11 pregnancies, 2 CF women had diabetes mellitus and 3 developed gestational diabetes. One pregnancy occurred in a mother with a transplanted lung. Of the 12 neonates, 3 were preterm and one was born with esophageal atresia. No miscarriages, terminations or neonatal mortalities occurred. Although most of the CF mothers had FEV_1[2] below 55% before pregnancy, the maternal and neonatal outcome was favorable and lung function tests generally remained stable.

Conclusions: We conclude that pregnancy in CF is feasible with a positive maternal and neonatal outcome. Early participation of the CF physician in the wish of the CF woman to reproduce is required. The integration of an intensive multidisciplinary approach during pregnancy, which includes close follow-up of maternal and fetal condition by the various specialists, should ensure an optimal outcome.

Background: The external approach is the golden standard for sinonasal tumor removal but it is associated with several side effects, including facial scars, intracranial and extracranial complications, a long hospitalization period and high costs. Endoscopic sinus surgery enables resection of benign and selected malignant sinonasal tumors and has the advantages of no facial scars, better functional and structural preservation of the sinonasal complex, minimal trauma to surrounding tissue, a shorter hospitalization stay and lower costs.

Objectives: To evaluate the advantages and limitations of endoscopic resection of benign and malignant sinonasal tumors, their recurrence and complication rates.

Methods: The medical and radiology records of 56 patients who underwent endonasal endoscopic resection of benign and malignant sinonasal tumors between 1996 and 2003 were retrospectively reviewed. Tumors located in the center of the nose and sinuses were endoscopically resected.

Results: Six cases of malignant tumor and 50 cases of benign tumor underwent resection by ESS[1]. One of the patients with malignant tumor died, the remainder showing no evidence of disease on follow-up of 3–60 months (mean 26.8 months). Inverted papilloma was the most common benign tumor (40 patients). Seven patients (18%) had recurrence followed by endonasal resection. No major complications were recorded. Hospitalization stay was 2–7 days (mean 3.6 days).

Conclusions: Endoscopic resection of benign sinonasal tumors that are centrally located in the nose and sinuses should be considered before the external approach is used. In very carefully selected cases of malignant tumors ESS is oncologically acceptable, but more experience is needed for discerning the indications for endoscopic resection of malignant tumors. The complication rate for endoscopic resection is low, there are no facial scars, hospitalization stay is short, and costs are low.

Background: Eyes scheduled for posterior segment surgery may have cataract, which obscures the visualization of the retina. Surgery may be carried out either by a two-step procedure: i.e., removal of the cataract followed later by posterior segment surgery; or it may be done in a single session: i.e., combined surgery of both the anterior and posterior segments.

Objective: To evaluate the outcomes of combined surgery by phacoemulsification and vitrectomy.

Methods: We retrospectively reviewed the records of 42 patients with coexisting cataract and vitreoretinal disease who underwent combined surgery by phacoemulsification and pars plana vitrectomy at one session.

Results: Indications for surgery were vitreous hemorrhage in 71.4%, retinal detachment in 11.9%, macular hole in 11.9%, and epiretinal membrane in 4.8%. There were no significant intraoperative complications.The main early postsurgical complications were fibrinous formation in 11.9%, elevated intraocular pressure in 23.8%, and recurrent vitreous hemorrhage in 9.5%. There were a few late complications related to phacoemulsification: posterior synechia in 9.5%, posterior capsular opacification in 7.1%, and dislocating intraocular lens in 4.8%. Recurrent retinal detachment occurred in five eyes and rubeoisis iridis in one. Visual acuity was improved in 85.8%, stable in 7.1% and worse in 7.1%.

Conclusions: Phacoemulsification performed at the time of posterior segment surgery enables good visualization during the vitrectomy, facilitates surgery, and is associated with only minor complications. In cases with cataract and vitreoretinal diseases, combined surgery by phacoemulsification and vitrectomy in one session may be considered.
 

Background: The mortality rate associated with congenital heart surgery is apparently related to caseload.

Objective: To determine whether an increase in caseload over the long term at a single center affects management and outcome in children undergoing cardiac surgery.

Methods: Data were collected prospectively over a 4 year period from the computerized registry of the hospital’s pediatric intensive care unit. Five parameters were analyzed: age at surgery, type of surgery, preventive measures (open chest), surgery-related and other complications (diaphragm paralysis and acute renal failure, respectively), and mortality. The data of a single-type surgery (arterial switch) were analyzed for bypass time and mechanical ventilation on an annual basis.

Results: The age distribution changed over the years, with more children under 1 year of age (20% newborns) undergoing surgery by the fourth year of the study. The caseload increased from 216 in the first year to 330 in the fourth, with a concomitant decrease in mortality rate from 4.9% to 3.2%. The chest was left open in 3.2% of patients in the first year and in 9.2% in the fourth year. The rate of diaphragm paralysis decreased from 6% to 2.4%. Death due to acute renal failure in patients requiring dialysis decreased from more than 80% in the first 2 years to 36% in the last two. These changes show an improvement but failed to reach statistical significance. Regarding the arterial switch operation, there was a significant improvement in pump time and duration of mechanical ventilation.

Conclusions: The increase in caseload in pediatric cardiac surgery was accompanied by improved management, with a lower complications-related mortality rate. We suggest that for optimal care of children with congenital heart disorders, quality management resources should be concentrated in centers with high caseloads.
