A retrospective review of intensive care management of organophosphate insecticide poisoning: Single center experience.

BACKGROUND: Organophosphate (OP) compounds are used as insecticides. Given the widespread availability and use of these chemicals, OP poisoning is quite common following either accidental or intentional exposures. Immediate intensive care management can save lives in these patients. We aimed to investigate intensive care management provided to OP poisoning patients in a tertiary care hospital in Turkey. SUBJECTS AND METHODS: This was a retrospective chart review of 62 patients, admitted to the Intensive Care Unit (ICU) with OP poisoning between 2000 and 2012. RESULTS: Of the 62 patients studied, 40 (65%) were male, 45 (73%) were suicide attempts, 59 (95%) ingested the OP compounds, and three patients (5%) (two patients with suicide and 1 with accidental exposure) died in the ICU. There were statistically significant differences between survivors and nonsurvivors for Glasgow Coma Scale (GCS) on admission (P = 0.034), Acute Physiology and Chronic Health Evaluation II (APACHE II) score (P = 0.003), Sequential Organ Failure Assessment (SOFA) score (P = 0.024), time to initiation of treatment (P = 0.034) and serum lactate dehydrogenase (LDH) levels (P = 0.007). CONCLUSIONS: Organophosphate poisoning is a life-threatening condition that requires immediate diagnosis and management. GCS, APACHE II score, SOFA score, and time to admission to the emergency department and LDH levels can provide prognostic information and predict outcomes.

Outcomes of percutaneous endoscopic gastrostomy in hospitalized patients at a tertiary care center in Turkey.

BACKGROUND/OBJECTIVES: The aim of this study was to perform a retrospective analysis characterizing patients receiving tube feeding following percutaneous endoscopic gastrostomy (PEG) tube placement between 2004 and 2012 at Erciyes University Hospital in Turkey. SUBJECTS/METHODS: Patients above the age of 18 years who required long-term enteral tube feeding were studied. All PEGs were performed using the pull-through technique by one experienced endoscopist. Demographic, clinical outcomes and PEG-related complication data were collected. RESULTS: Of the 128 subjects studied, 91 were men (71%) and 37 were women (29%). The mean age of this patient population was 54 ± 19 years. The most common reason for PEG tube insertion was the inability to consume oral diet due to complications of cerebrovascular disease (27%), while cerebral hypoxia, occurring after nonneurological medical disorders, was the second most common indication (23%). A total of 70 patients (55%) had chronic comorbidities, with hypertension being the most common (20%). The most common procedure-related complication was insertion-site bleeding, which occurred in 4% of patients. Long-term complications during 1 year were insertion-site cellulitis, gastric contents leakage and peristomal ulceration, which occurred in 14%, 5% and 0.5% of patients, respectively. There were no PEG insertion-related mortalities; 1-year mortality was unrelated to the indication for PEG tube insertion. CONCLUSIONS: PEG tube insertion was a safe method to provide enteral access for nutrition support in this hospitalized patient population.

A nurse-led ocular oncology clinic in Liverpool: results of a 6-month trial.

PURPOSE: To describe the design and implementation of a nurse-led clinic in a tertiary adult ocular oncology service and to assess its feasibility and patient satisfaction. METHODS: Patients with a melanocytic uveal tumour attending for review during an initial 6-month trial period were assessed in a dedicated ocular oncology clinic by an ophthalmic nurse practitioner. These were: (1) patients who would have been discharged back to the referring hospital but whose ophthalmologist refused to continue their follow-up; (2) patients who preferred to be reviewed in our clinic; and (3) patients with a risk of metastatic disease that was increased but not enough for them to be referred to our medical oncologist. Quality assurance mechanisms were established to ensure safe practice. Patient satisfaction was assessed by means of anonymised questionnaires. RESULTS: A total of 65 patients were seen between 1 November 2011 and 31 May 2011. The mean age was 58 years (range 16-82 years). Most lesions seen were choroidal suspicious naevi (54%) and treated choroidal malignant melanomas (20%). Nine (14%) patients with an increased risk of metastatic disease attended the clinic. Nine patients (14%) were referred back to the ophthalmologist's ocular oncology clinic, because of tumour growth in two patients, macular oedema in one, cataract in five, and conjunctival melanosis at the plaque site in one. Questionnaires showed high levels of satisfaction with the service. CONCLUSION: A nurse-led adult ocular oncology clinic is feasible, thanks to developments in ocular photography. It is well accepted by patients.

Three-dimensional analysis of 61 human endolymphatic ducts and sacs in ears with and without Menière's disease.

We used light microscopy and computerized graphic reconstruction techniques to examine the endolymphatic duct and sac in 20 pairs of bones from patients with Menière's disease and 21 bones from controls. The diameters of the endolymphatic duct and the proximal portion of the vestibular aqueduct were significantly smaller in Menière's disease ears than in controls. Graphic reconstructions showed the Menière's sacs to be smaller and to have fewer tubular epithelial structures in the intraosseous portion than in the control ears. The median volume of the sac in the Menière's disease side was substantially lower than in the contralateral ear. The width of the external aperture of the vestibular aqueduct was significantly smaller in Menière's disease ears than in controls. These findings indicate that the size not only of the vestibular aqueduct but also of the sac is reduced in Menière's disease. The results may suggest that the endolymphatic sac is pathologically changed in Menière's disease and that a reduced resorptive capacity of a small endolymphatic sac could result in endolymphatic hydrops.

Immunohistochemical localization of vimentin and S-100 antigen in small acoustic tumors and adjacent cochlear nerves.

To clarify the involvement of cochlear nerves in small acoustic tumors, we used immunoperoxidase techniques to determine the presence and distribution of vimentin and S-100 antigens in two acoustic tumor specimens and a transected vestibular nerve. Schwann cells and acoustic tumor cells failed to react positively with monoclonal antibody to vimentin. Reaction was observed in mesenchymal-appearing cells within both the normal nerve and the acoustic tumors, predominantly in association with blood vessels. Normal schwann cells and acoustic tumor cells reacted with polyclonal antibody to S-100 antigen with a similar, uniform distribution. Mesenchymal-appearing cells did not react with antibody to S-100. Immunostaining of a vestibular nerve from a Meniere's disease patient, used as a control, did not differ significantly from nerves adjacent to acoustic tumors. Because tumor cells and normal schwann cells stained similarly with antibody to S-100, it was not possible to establish with certainty if tumor cells invaded adjacent nerves.

Familial Treacher-Collins syndrome.

The major congenital malformations of the first and second branchial arch derivatives such as mandibulofacial dysostosis have a genetic basis. Treacher-Collins syndrome is transmitted as an autosomal dominant trait, although many cases occur as spontaneous mutations. The characteristics are hypoplasia of the malar, mandibular and maxillary bones, antimongoloid slanting of the palpebral fissures and a receding chin. The aural findings include malpositioning or maldevelopment of the pinna or external auditory meatus, an atretic bony plate instead of tympanic membrane, or ossicular malformations. Five members of a Hindu family affected by Treacher-Collins syndrome spanning three generations are examined in detail, with special reference to their hearing.

Absence of Dermatitis Among Rubber Plantation Workers.

None of the 40 rubber plantation workers exposed to latex for many years examined by us, had developed any significant dermatitis apart from thickening and lichenification of the dorsal aspect of right index finger and medial aspect of right thumb.
