Eight years experience from a skeletal dysplasia referral center in a tertiary hospital in Southern India: A model for the diagnosis and treatment of rare diseases in a developing country.

We report on a series of 514 consecutive diagnoses of skeletal dysplasia made over an 8-year period at a tertiary hospital in Kerala, India. The most common diagnostic groups were dysostosis multiplex group (n = 73) followed by FGFR3 (n = 49) and osteogenesis imperfecta and decreased bone density group (n = 41). Molecular confirmation was obtained in 109 cases. Clinical and radiographic evaluation was obtained in close diagnostic collaboration with expert groups abroad through Internet communication for difficult cases. This has allowed for targeted biochemical and molecular studies leading to the correct identification of rare or novel conditions, which has not only helped affected families by allowing for improved genetic counseling and prenatal diagnosis but also resulted in several scientific contributions. We conclude that (1) the spectrum of genetic bone disease in Kerala, India, is similar to that of other parts of the world, but recessive entities may be more frequent because of widespread consanguinity; (2) prenatal detection of skeletal dysplasias remains relatively rare because of limited access to expert prenatal ultrasound facilities; (3) because of the low accessibility to molecular tests, precise clinical-radiographic phenotyping remains the mainstay of diagnosis and counseling and of gatekeeping to efficient laboratory testing; (4) good phenotyping allows, a significant contribution to the recognition and characterization of novel entities. We suggest that the tight collaboration between a local reference center with dedicated personnel and expert diagnostic networks may be a proficient model to bring current diagnostics to developing countries. © 2014 Wiley Periodicals, Inc.

Neuropathy after herniorrhaphy: indication for surgical treatment and outcome.

BACKGROUND: Chronic neuropathy after hernia repair is a neglected problem as very few patients are referred for surgical treatment. The aim of the present study was to assess the outcome of standardized surgical revision for neuropathic pain after hernia repair. METHODS: In a prospective cohort study we evaluated all patients admitted to our tertiary referral center for surgical treatment of persistent neuropathic pain after primary herniorrhaphy between 2001 and 2006. Diagnosis of neuropathic pain was based on clinical findings and a positive Tinel's sign. Postoperative pain was evaluated by a visual analogue scale (VAS) and a pain questionnaire up to 12 months after revision surgery. RESULTS: Forty-three consecutive patients (39 male, median age 35 years) underwent surgical revision, mesh removal, and radical neurectomy. The median operative time was 58 min (range: 45-95 min). Histological examination revealed nerve entrapment, complete transection, or traumatic neuroma in all patients. The ilioinguinal nerve was affected in 35 patients (81%); the iliohypogastric nerve, in 10 patients (23%). Overall pain (median VAS) decreased permanently after surgery within a follow-up period of 12 months (preoperative 74 [range: 53-87] months versus 0 [range: 0-34] months; p<0.0001). CONCLUSIONS: The results of this cohort study suggest that surgical mesh removal with ilioinguinal and iliohypogastric neurectomy is a successful treatment in patients with neuropathic pain after hernia repair.

Clinical manifestations of mucous membrane pemphigoid in a tertiary center.

Mucous membrane pemphigoid (MMP) is a progressive inflammatory disease of autoimmune etiology. We performed a retrospective analysis of clinical signs and treatment on 16 patients. Conjunctival biopsies were performed in all patients and showed typical immuno-deposits at the basement membrane zone. The mean age at presentation was 69 years, 60 % were female.12 patients demonstrated ocular involvement (11 bilaterally). At the time of referral to our hospital, 92 % had reached an advanced stage III or IV. All patients presented conjunctival fibrosis with resultant fornix foreshortening. Trichiasis and symblepharon were found in 11 patients. Keratitis was found in 11 patients resulting in ulceration in 5 cases. Complications required surgical interventions included: entropion surgery (n = 2), tarsorrhaphy (n = 1), amniotic membrane transplantation (n = 2), keratoplasty (n = 1). Systemic immunomodulatory therapy is the treatment of choice. Dapsone (n = 8), steroids (n = 8), azathioprine (n = 5), cyclophosphamide (n = 2), mycophenolate mofetil (n = 4) and methotrexate (n = 1) were used concomitantly or consecutively. Early diagnosis can prevent ocular complications. Immunomodulatory therapy has provided an avenue for preserving vision. The management of MMP requires a multidisciplinary approach.

Treatment of status epilepticus: a comparison of phenytoin, valproate, or levetiracetam

Objectives: Phenytoin (PHT), valproic acid (VPA), or levetiracetam (LEV) are commonly used as second-line treatment of status epilepticus (SE), but comparative studies are not available to date.Methods: In our tertiary care hospital, among 279 SE episodes prospectively collected over four years, and occurring in adults, we identified 187 episodes in which PHT, VPA or LEV were prescribed after benzodiazepines. Patients with post-anoxic SE were not included. Demographics, clinical SE features, failure of second-line treatment to control SE, new handicap and mortality at hospital discharge were assessed. Uni- and multivariable statistical analyses were applied to compare the three agents.Results: Each compound was used in about one third of episodes. VPA failed to control SE in 25.4%, PHT in 41.4% and LEV in 48.3% of episodes in which these were prescribed as second-line agents. After adjustment for known SE outcome predictors, LEV failed more often than VPA (OR 2.69; 95% CI 1.19-6.08); in others words, 16.8% (95% CI 6.0-31.4%) of second-line treatment failures could be attributed to prescription for LEV instead of VPA. PHT was statistically not different from the other two compounds. At discharge, second-line treatment did not influence new handicap and mortality, while etiology and severity of the SE episode were robust independent predictors.Conclusions: Even without significant differences on outcome at discharge, LEV seems less efficcacious than VPA to control SE after benzodiazepines. A prospective comparative trial is needed to address this potentially concerning finding. The second interesting finding is that the outcome seems more influenced by the SE characteristics than the treatment.

Head-to-head comparison of length of stay, patients' outcome and satisfaction in Switzerland before and after SwissDRG-Implementation in 2012 in 2012: an observational study in two tertiary university centers.

On 1 January 2012 Swiss Diagnosis Related Groups (DRG), a new uniform payment system for in-patients was introduced in Switzerland with the intention to replace a "cost-based" with a "case-based" reimbursement system to increase efficiency. With the introduction of the new payment system we aim to answer questions raised regarding length of stay as well as patients' outcome and satisfaction. This is a prospective, two-centre observational cohort study with data from University Hospital Basel and the Cantonal Hospital Aarau, Switzerland, from January to June 2011 and 2012, respectively. Consecutive in-patients with the main diagnosis of either community-acquired pneumonia, exacerbation of COPD, acute heart failure or hip fracture were included. A questionnaire survey was sent out after discharge investigating changes before and after SwissDRG implementation. Our primary endpoint was LOS. Of 1,983 eligible patients 841 returned the questionnaire and were included into the analysis (429 in 2011, 412 in 2012). The median age was 76.7 years (50.8% male). Patients in the two years were well balanced in regard to main diagnoses and co-morbidities. Mean LOS in the overall patient population was 10.0 days and comparable between the 2011 cohort and the 2012 cohort (9.7 vs 10.3; p = 0.43). Overall satisfaction with care changed only slightly after introduction of SwissDRG and remained high (89.0% vs 87.8%; p = 0.429). Investigating the influence of the implementation of SwissDRG in 2012 regarding LOS patients' outcome and satisfaction, we found no significant changes. However, we observed some noteworthy trends, which should be monitored closely.

Second-line status epilepticus treatment: comparison of phenytoin, valproate, and levetiracetam.

Purpose:  Phenytoin (PHT), valproic acid (VPA), or levetiracetam (LEV) are commonly used as second-line treatment of status epilepticus (SE), but comparative studies are not available. Methods:  Among 279 adult SE episodes identified prospectively in our tertiary care hospital over 4 years, we retrospectively identified 187 episodes in which PHT, VPA, or LEV were given after benzodiazepines. Patients with postanoxic SE were not included. Demographics, clinical SE features, failure of second-line treatment to control SE, new handicap, and mortality at hospital discharge were assessed. Uni- and multivariable statistical analyses were applied to compare the three agents. Key Findings:  Each compound was used in about one third of SE episodes. VPA failed to control SE in 25.4%, PHT in 41.4%, and LEV in 48.3% of episodes in which these were prescribed. A deadly etiology was more frequent in the VPA group, whereas SE episodes tended to be more severe in the PHT group. After adjustment for these known SE outcome predictors, LEV failed more often than VPA [odds ratio (OR) 2.69; 95% confidence interval (CI) 1.19-6.08]; 16.8% (95% CI: 6.0-31.4%) of second-line treatment failures could be attributed to LEV. PHT was not statistically different from the other two compounds. Second-line treatment did not seem to influence new handicap and mortality, whereas etiology and the SE Severity Score (STESS) were robust independent predictors. Significance:  Even without significant differences on outcome at discharge, LEV seems less efficient than VPA to control SE after benzodiazepines. A prospective comparative trial is needed to address this potentially concerning finding.

Telementoring during endovascular treatment of abdominal aortic aneurysms: a prospective study.

PURPOSE: To explore the use of telementoring for distant teaching and training in endovascular aortic aneurysm repair (EVAR). METHODS: According to a prospectively designed study protocol, 48 patients underwent EVAR: the first 12 patients (group A) were treated at a secondary care center by an experienced interventionist, who was training the local team; a further 12 patients (group B) were operated by the local team at their secondary center with telementoring by the experienced operator from an adjacent suite; and the last 24 patients (group C) were operated by the local team with remote telementoring support from the experienced interventionist at a tertiary care center. Telementoring was performed using 3 video sources; images were transmitted using 4 ISDN lines. EVAR was performed using intravascular ultrasound and simultaneous fluoroscopy to obtain road mapping of the abdominal aorta and its branches, as well as for identifying the origins of the renal arteries, assessing the aortic neck, and monitoring the attachment of the stent-graft proximally and distally. RESULTS: Average duration of telementoring was 2.1 hours during the first 12 patients (group B) and 1.2 hours for the remaining 24 patients (group C). There was no difference in procedural duration (127+/-59 minutes in group A, 120+/-4 minutes in group B, and 119+/-39 minutes in group C; p=0.94) or the mean time spent in the ICU (26+/-15 hours in group A, 22+/-2 hours in group B, and 22+/-11 hours for group C; p=0.95). The length of hospital stay (11+/-4 days in group A, 9+/-4 days in group B, and 7+/-1 days in group C; p=0.002) was significantly different only for group C versus A (p=0.002). Only 1 (8.3%) patient (in group A: EVAR performed by the experienced operator) required conversion to open surgery because of iliac artery rupture. This was the only conversion (and the only death) in the entire study group (1/12 in group A versus 0/36 in groups B + C, p=0.31). CONCLUSIONS: Telementoring for EVAR is feasible and shows promising results. It may serve as a model for development of similar projects for teaching other invasive procedures in cardiovascular medicine.

Multidisciplinary approach of lumbo-sacral chordoma: From oncological treatment to reconstructive surgery.

Lumbo-sacral chordoma is a rare, slow-growing tumor, arising from embryonic nothocordal remnants. Wide en bloc excision with clear margins remains mandatory to achieve satisfactory recurrence rates and disease-free survival. No chemotherapy has been demonstrated to be effective and radiotherapy is only marginally effective. Tyrosine kinase receptor inhibitors have showed encouraging results in locally advanced and metastatic chordoma. Reconstructive surgery may become very complex. Multidisciplinary approach in tertiary hospitals is always necessary. J. Surg. Oncol. 2015; 112:544-554. © 2015 Wiley Periodicals, Inc.
