Treatment with inhaled aerosolised ethanol reduces viral load and potentiates macrophage responses in an established influenza mouse model

AIM

Treatment options for viral lung infections are currently limited. We aimed to explore the safety and efficacy of inhaled ethanol in an influenza-infection mouse model.

MATERIALS AND METHODS

In a safety and tolerability experiment, 80 healthy female BALB/c mice (20 per group) were exposed to nebulized saline (control) or three concentrations of ethanol (40/60/80% ethanol v/v in water) for 3x30-minute periods, with a two-hour break between exposures. In a separate subsequent experiment, 40 Female BALB/c mice were nasally inoculated with 104.5 plaque-forming units of immediate virulence "Mem71" influenza. Infection was established for 48-h before commencing treatment in 4 groups of 10 mice with either nebulized saline (control) or one of 3 different concentrations of ethanol (40/60/80% ethanol v/v in water) for 3x30-minute periods daily over three consecutive days. In both experiments, mouse behavior, clinical scores, weight change, bronchoalveolar lavage cell viability, cellular composition, and cytokine levels, were assessed 24-h following the final exposure, with viral load also assessed after the second experiment.

RESULTS

In uninfected BALB/c mice, 3x30-minute exposures to nebulized 40%, 60%, and 80% ethanol resulted in no significant differences in mouse weights, cell counts/viability, cytokines, or morphometry measures. In Mem71-influenza infected mice, we observed a dose-dependent reduction in viral load in the 80%-treated group and potentiation of macrophage numbers in the 60%- and 80%-treated groups, with no safety concerns.

CONCLUSIONS

Our data provides support for inhaled ethanol as a candidate treatment for respiratory infections.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

366 An Audit of Electronic Discharge Summaries and the Impact of Dedicated Teaching and Training in an Emergency Surgical Unit

Introduction

Electronic discharge summary forms a vital part of a patient’s journey. As established in GAIN Guidelines 2011 ‘Clear and complete documentation in a patient’s health record is directly linked to the quality of the care they receive’. By improving the quality of E-Discharge summaries this will help to improve patient outcomes.

Method

In the Emergency surgical unit [EMSU] there are over 3500 completed consultant episodes per annum. We audited the quality of E-Discharges using 33 separate parameters included in the Trust’s dedicated discharge proforma. An E-Discharge summary was considered acceptable if >90% of the information was recorded accurately. Discharge failure rate was audited in a randomised sample of 20 discharges in November 2019 and one year later in November 2020 following implementation of specific training and teaching at induction on E-Discharge compilation.

Results

In November 2019 the discharge failure rate was 60%. Common failings were in general omission of data, lack of follow-up planning and inaccurate pharmaceutical arrangements. In November 2020, following dedicated teaching at induction, failure rate was 15%. Where accurate recording of demographic information and pertinent inpatient detail improved, shortcomings remained in inadequate recording of follow-up care and ongoing involvement of the primary healthcare team.

Conclusions

E-Discharge recording is sub-standard. It is often the remit of the least experienced member of the medical team, as is the case in our unit. We have shown that dedicated teaching and training in this area can improve the quality of discharge summaries.

980 An Audit of a Surgical Ambulatory Service [SAmS] Performance Pre And Post COVID-19 - The Impact of Senior Decision Making

Introduction

Surgical Ambulatory Units have emerged to refine the management of unscheduled care with the aim of reducing admissions and offering timely, accurate treatment strategies. There are 12 principles which underpin an efficient ambulatory Service, one of which is to have a 'Consultant led and delivered Service'. Consequent to the COVID Pandemic we reallocated Consultants to our Ambulatory Service and reviewed the impact of this initiative.

Method

Two periods - Pre COVID 6-17/1/20 and Post COVID 27/4 -10/5/20 were compared with respect to volume, case mix, procedures performed and outcomes in terms of investigations, and completed episodes. Data was retrieved from case notes and electronic databases.

Results

There were no demographic differences across the groups. The case mix and referral patterns were similar as was the volume. There were no differences in procedures or investigations ordered. In the Pre COVID group 20% of sessions were Consultant led compared with 100% in the Post COVID group. In the post COVID group 64% of cases were completed on the index attendance compared with 27% in the pre COVID group.

Conclusions

A Consultant presence in SAmS enhances decision making and risk management and is critical for the efficacy of the Service with respect to patient flow and resource management.

Role of Tris-CaEDTA as an adjuvant with nebulised tobramycin in cystic fibrosis patients with Pseudomonas aeruginosa lung infections: A randomised controlled trial

BACKGROUND

We tested if disrupting iron utilisation by P. aeruginosa by adding the Tris-buffered chelating agent CaEDTA to nebulised tobramycin would enhance bacterial clearance and improve lung function in CF patients.

METHODS

In this double-blind, randomised controlled trial, 26 episodes (25 patients) with P. aeruginosa infection admitted to two CF centres for treatment of an acute pulmonary exacerbation were randomly assigned to receive either 75 mg CaEDTA in Tris-buffered saline or placebo (Tris-buffered saline) nebulised in combination with 250 mg tobramycin twice daily for six weeks followed with four week safety follow-up. Primary endpoints were safety, tolerability, and bacterial density of P. aeruginosa. A secondary endpoint was lung function.

RESULTS

The study drug was well tolerated with adverse events comparable in both groups. The mean (SD) reduction in sputum P. aeruginosa count (log₁₀ CFU/g) in the CaEDTA vs placebo group was 2·05 (2·57) vs 0·82 (2·71) at two weeks relative to admission (p = 0·39). The mean improvement in ppFEV₁ was 16 vs 5 (p = 0·16); 11 vs 2 (p = 0·28); and 6 vs 2 percentage points (p = 0·47) at two, six, and ten weeks in CaEDTA and placebo groups, respectively.

CONCLUSIONS

In this pilot study in CF patients, an increase in the reduction of sputum density of P. aeruginosa and an increase in ppFEV₁ was observed in the group of patients who received Tris-CaEDTA added to inhaled tobramycin compared to the group who received inhaled tobramycin alone, although these differences were not statistically significant. The treatment was also shown to be safe.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

13 Amending Admission Protocol to Reduce Proton Pump Inhibitor-Induced Hyponatraemia on A Specialist Hip Fracture Unit

Introduction

Hyponatraemia is a common electrolyte disturbance amongst elderly patients. Defined as a sodium concentration below 135 mmol/L, the BNF cites hyponatraemia as a ‘rare’ side effect of Omeprazole, a common proton pump inhibitor (PPI). In elderly patients, hyponatraemia can have significant morbidity.

On our Hip Fracture Unit (HFU) at St Helier Hospital, all patients are commenced on Omeprazole on admission. We conducted a quality improvement project to reduce the incidence of PPI-induced hyponatraemia by altering standard protocol from Omeprazole to Ranitidine.

Methods

Phase 1: Retrospective analysis identifying incidence of PPI-induced hyponatraemia, defined as sodium concentration below 133mmol/L on two consecutive readings and resolving on switching to Ranitidine (Group A: n=86).

Phase 2: Identifying incidence of hyponatraemia following administration of Ranitidine from admission (Group B: n=62).

Exclusion criteria: Patients already on gastric protection or hyponatraemic on presentation. Chi squared analysis to establish statistical significance for risk of hyponatraemia associated with omeprazole.

Results

Total number of patients was 148. Age range 60-101 years (median 82 years). Incidence of PPI-induced hyponatraemia in Group A was 10.5% (9 cases). All resolved on switching to ranitidine.

Following change in admission protocol to Ranitidine (Group B), incidence of hyponatraemia was 1.6% (1 case). The chance of developing hyponatraemia with Omeprazole was significantly higher than with ranitidine (P=0.0454).

Conclusions

10.5% of admissions to the HFU experienced PPI-induced hyponatraemia. The European Medicines Agency defines side effects occurring at greater than 10% as very common. Whilst 45% of patients were on medication associated with hyponatraemia on admission, the absence of hyponatraemia at presentation and biochemical response when switching to ranitidine, demonstrates this is a significant side effect of PPIs. Given the increased morbidity associated with hyponatraemia, particularly in frail, elderly patients, amending protocol to ranitidine for gastric protection has the potential to reduce harm and improve patient outcomes.

Abdominal abscess due to retained gallstones 5 years after laparoscopic cholecystectomy

A 76-year-old female patient with diabetes presented with pyrexia and a recurrent painful right sided loin swelling. One year previously she had undergone radiological drainage of a large right sided loin abscess. At index presentation she was investigated both radiologically and endoscopically and a source for the abscess was not found. On this presentation, a computed tomography scan confirmed a large retroperitoneal abscess pointing through the lateral abdominal wall musculature. Surgical drainage was undertaken whereby the abscess was drained and several large gallstones extruded through the incision. The patient subsequently recuperated and the wound has healed successfully by second intention. Five years previously the patient had undergone an "uncomplicated" laparoscopic cholecystectomy. This case highlights the catastrophic late effects of dropped gallstones during laparoscopic cholecystectomy.

Effects of vasectomy on spermatogenesis and fertility outcome after testicular sperm extraction combined with ICSI

BACKGROUND

Each year 40,000 men have a vasectomy in the UK whilst another 2400 request a reversal to begin a second family. Sperm can now be obtained by testicular biopsy and subsequently used in assisted conception with ICSI. The study aims were to compare sperm yields of men post-vasectomy or with obstructive azoospermia (OA) of unknown aetiology with yields of fertile men and to assess any alteration in the clinical pregnancy rates after ICSI.

METHODS

Testicular tissue was obtained by Trucut needle from men who had undergone a vasectomy >5 years previously or had OA from other causes and from fertile men during vasectomy. Seminiferous tubules were milked to measure sperm yields. Numbers of Sertoli cells and spermatids and thickness of the seminiferous tubule walls were assessed using quantitative computerized analysis.

RESULTS AND CONCLUSIONS

Sperm yields/g testis were significantly decreased in men post-vasectomy and in men with OA, relative to fertile men. Significant reductions were also observed in early (40%) and mature (29%) spermatid numbers and an increase of 31% was seen in the seminiferous tubule wall (basal membrane and collagen thickness) of vasectomized men compared with fertile men. Clinical pregnancy rates in couples who had had a vasectomy were also significantly reduced.

Diagnosis of cystic fibrosis after newborn screening: the Australasian experience--twenty years and five million babies later: a consensus statement from the Australasian Paediatric Respiratory Group

Newborn screening for cystic fibrosis has been used in Australia and New Zealand for over 20 years. In that time, considerable experience has been developed regarding the early diagnosis of cystic fibrosis after newborn screening. To date, there has not been a consensus on the process of screening and clinical evaluation leading to the diagnosis of cystic fibrosis in infants, many of whom are not symptomatic at time of notification of the screening result. The aim of this paper is to provide some consensus on the important issues of a cystic fibrosis diagnosis arising from newborn screening, based on the experience gained in Australia and New Zealand over the last 20 years.

A new asthma spacer device to improve compliance in children: a pilot study

OBJECTIVE

This pilot study was designed to compare the acceptance, ease of use, and effects on compliance between currently used spacer devices and the Funhaler--a new small volume spacer device designed to improve adherence to asthma medication in children.

METHODOLOGY

A matched questionnaire-based survey was conducted by two interviews of each caregiver by the same person. A total of 32 children were randomly recruited from seven clinics spanning widely differing socioeconomic and geographical areas of Perth, Western Australia. Preschool children taking regular inhaled asthma medication using an existing low volume spacer device and aged between 1.5 and 6 years, took part in the pilot study. Parents completed two matched questionnaires. The first questionnaire was completed at the beginning of the study and the second after 2 weeks' use of the Funhaler spacer. Data collected related primarily to ease of use of the devices, child and parental compliance, and treatment attitudes. During the study, parents were also called at random on one occasion to ascertain whether they had attempted to medicate their child the previous day.

RESULTS

Using the Funhaler incentive spacer device, parents reported significantly more success at medicating their children (22/30 always successful) in comparison to using their existing spacer device (3/30). Parental adherence to prescribed frequency and the delivery technique of children were also improved. The children also showed improved satisfaction and willingness to use the device and parents' attitude towards medicating their children was improved with the Funhaler spacer device.

CONCLUSIONS

Use of a novel, incentive spacer device (Funhaler) appeared to be associated with increased success and fewer problems in medicating children, improved child and parental adherence, and a more positive attitude towards treatment, suggesting that more extensive long-term efficacy trials with the device are warranted.

Funhaler spacer: improving adherence without compromising delivery

A novel asthma spacer device, the "Funhaler", incorporates incentive toys which are isolated from the main inspiratory circuit by a valve. Here we show that its use does not compromise drug delivery. Improved adherence combined with satisfactory delivery characteristics suggest that the Funhaler may be useful for management of young asthmatics.

What we need to know about bioterrorism preparedness: results from focus groups conducted at APIC 2000

Infection control practitioners (ICPs) are important partners in enhancing the US public health infrastructure, both as essential recipients of continuing education and as instructors responsible for providing this education. Focus groups were conducted at APIC 2000, the annual meeting for the Association for Professionals in Infection Control and Epidemiology, Inc, to determine the ICPs' priorities for educational opportunities in bioterrorism preparedness and the preferred methods of education delivery. Focus group participants affirmed the need to provide education in sessions of less than 60 minutes, with use of a variety of technologies and methods of presentation such as video, Internet, and paper-based self-learning texts. The participants' comments suggested a lack of awareness by employees in health care institutions about the potential threat of bioterrorism in the United States and a deficiency in knowledge about the potential consequences of an attack. The focus group participants believed this lack of awareness also leads to unwillingness by their administrators to allocate funds for planning and education. Since it appears that ICPs will be looking for direction and expertise from the local health departments in their communities, the first subset of professionals to target for bioterrorism education and preparedness should probably be the public health professionals.

Thyroid papillary carcinoma in lateral neck cyst: missed primary tumour or ectopic thyroid carcinoma within a branchial cyst?

We report a case of thyroid papillary carcinoma lying within a lateral cervical cyst for which no occult primary tumour of the thyroid was identified. We explore the possible diagnoses and include a discussion of how ectopic thyroid tissue may come to lie within a branchial cyst.

Herpes simplex virus type 1 infection stimulates p38/c-Jun N-terminal mitogen-activated protein kinase pathways and activates transcription factor AP-1

Cells respond to environmental stress and proinflammatory cytokines by stimulating the Jun N-terminal kinase/stress-activated protein kinase (JNK/SAPK) and the p38 mitogen-activated protein kinase cascades. Infection of eukaryotic cells with herpes simplex virus type 1 (HSV-1) resulted in stimulation of both JNK/SAPK and p38 mitogen-activated protein kinase after 3 h of infection, and activation reached a maximum of 4-fold by 9 h post-infection. By using a series of mutant viruses, we showed that the virion transactivator protein VP16 stimulates p38/JNK, whereas no immediate-early, early, or late viral expressed gene is involved. We identified the stress-activated protein kinase kinase 1 as an upstream activator of p38/JNK, and we demonstrated that activation of AP-1 binding proceeded p38/JNK stimulation. During infection, the activated AP-1 consisted mainly of JunB and JunD with a simultaneous decrease in the cellular levels of Jun protein. We suggest that activation of the stress pathways by HSV-1 infection either represents a cascade triggered by the virus to facilitate the lytic cycle or a defense mechanism of the host cell against virus invasion.

Sumatriptan treatment for migraine in a health maintenance organization: economic, humanistic, and clinical outcomes

This study was undertaken to assess the impact of 12 months of sumatriptan therapy (6 mg subcutaneously) for migraine on health care use, health-related quality of life, productivity, patient satisfaction with the medication, and clinical efficacy in a health maintenance organization (HMO). One hundred forty-eight patients received open-label sumatriptan for 12 months for the treatment of migraine. Medical records were reviewed to obtain information on the frequency of migraine-related health care use during the 12 months before and during sumatriptan treatment. Patients completed questionnaires on their productivity at work, health-related quality of life, and satisfaction with medication at baseline and after 3, 6, and 12 months of sumatriptan treatment. For each migraine, patients recorded pain severity scores before and after taking sumatriptan and the time between dosing and onset of meaningful relief. Sumatriptan was associated with significant reductions in migraine-related use of general outpatient services, telephone calls, urgent care services, and emergency department visits (P < 0.05); a significant increase in the use of pharmacy services (P < 0.05); and significant and sustained improvements in health-related quality-of-life scores compared with baseline (P < 0.001). Patients lost significantly less time from work and were significantly more satisfied with sumatriptan compared with their usual therapy (P < 0.05). Two hours after dosing, 81% of patients experienced reduction of moderate or severe pain to mild or no pain, and 90% of all patients experienced meaningful relief of pain. The use of sumatriptan for 12 months in an HMO was associated with reductions in health care use and improved health-related quality of life, productivity, and patient satisfaction with medication.

When the biological indicator is positive: investigating autoclave failures

A series of positive biological indicators in steam autoclaves from different hospital departments within the same building were traced to blocked steam traps on building condensate lines. The steps taken during the investigation and a protocol for management of positive biological indicators are described.

Efficacy and tolerability of subcutaneous sumatriptan administered using the IMITREX STATdose System

The efficacy and tolerability of subcutaneous (SC) sumatriptan administered with the IMITREX (sumatriptan succinate) STATdose System, which circumvents the need for patients or health care professionals to handle a syringe, were evaluated in two randomized, double-masked, parallel-group, placebo-controlled, multicenter studies. In the clinic, 158 adults with migraine diagnosed according to International Headache Society criteria received SC sumatriptan (6 mg) or placebo delivered with the IMITREX STATdose System for treatment of a migraine attack. By 120 minutes after SC dosing, 73% and 79% of sumatriptan-treated patients, compared with 28% and 37% of placebo-treated patients in studies 1 and 2, respectively, experienced headache relief (a statistically significant difference). Clinical disability scores 120 minutes after dosing showed that 75% and 85% of sumatriptan-treated patients, compared with 30% and 42% of placebo-treated patients, were normal or only mildly impaired (a statistically significant difference). Similar efficacy rates were observed for nausea, phonophobia, and photophobia. No serious or unusual adverse events occurred, and no clinically relevant abnormalities in laboratory test values were reported. Based on these results, we concluded that SC sumatriptan (6 mg) administered using the IMITREX STATdose System is effective for the treatment of migraine. The efficacy and tolerability profiles of SC sumatriptan administered with this device are similar to those reported for SC sumatriptan administered with a conventional syringe.

Impact of sumatriptan on workplace productivity, nonwork activities, and health-related quality of life among hospital employees with migraine

This prospective, open-label study evaluated the effects of subcutaneous sumatriptan versus usual therapy on workplace productivity, activity time outside of work, and health-related quality of life in 43 men or women who were hospital employees diagnosed with migraine according to international Headache Society criteria. Patients treated migraines with their usual therapy for 12 to 18 weeks followed by subcutaneous sumatriptan for 6 months. Health-related quality of life measurements obtained at baseline, after usual therapy, and after sumatriptan therapy included the Short Form-36 Health Survey and the Migraine-Specific Quality of Life Questionnaire. Patient daily diaries were used to capture data on migraine symptoms and on Lost Workplace Productivity and Non-workplace Activity Time. Traditional clinical efficacy measures were obtained to support the pharmacoeconomic data. Clinical data showed that the percentage of treated migraine days per patient on which the patient experienced relief (moderate or severe pain reduced to mild or none) was 75% with sumatriptan and 25% with usual therapy. The mean time to meaningful relief was 1.1 hours during the sumatriptan phase and 4.2 hours during the usual therapy phase. Lost Workplace Productivity and Nonworkplace Activity Time was 35% lower with sumatriptan therapy (1.5 hours) compared with usual therapy (2.3 hours). Time missed from work due to symptoms, time worked with symptoms, and time normal activities were carried on with symptoms were each lower during sumatriptan therapy compared with usual therapy. Scores on each of the three Migraine-Specific Quality of Life Questionnaire dimensions and on the Role-Emotional dimension of the Short Form-36 were significantly more favorable after sumatriptan than after usual therapy (P < 0.05). These data demonstrate that treatment of migraines with sumatriptan for 6 months following usual therapy for 12 to 18 weeks was associated with improvement in clinical efficacy, reduction in lost workplace productivity and nonworkplace activity time, and enhancement of key dimensions of health-related quality of life among employees of a large university hospital.

Cystadenoma of spermatic cord resembling ovarian serous epithelial tumour of low malignant potential: immunohistochemical study suggesting Müllerian differentiation

A cystic lesion of the spermatic cord resembling an ovarian serous epithelial tumour of low malignant potential or borderline malignancy is reported. Immunohistochemical staining and electronmicroscopic examination suggested epithelial rather than mesothelial differentiation of the cyst lining cells. There was strong positive immunohistochemical staining of cyst lining cells for CA 125, providing evidence for Müllerian differentiation. A flow cytometric analysis of nuclear DNA content revealed a diploid profile.

A late, fatal complication of a high energy thermal injury to the scalp

Marjolin's ulcer is an uncommon condition in which malignant transformation occurs in a chronic inflammatory focus. It was originally described in association with a thermal injury, however, its occurrence with protean chronic inflammatory foci has been described. We report the occurrence of and aggressive squamous carcinoma 3 decades after a high voltage electric mark injury to the scalp. This is the first such case described in the literature. The case supportively highlights the role of chronic inflammation and sepsis in epidermal scar cancer development, and it underlines the importance of appropriate wound management initially and expeditious treatment of sepsis and resistant skin ulceration because the malignant behavior of these tumors is aggressive and unpredictable.

Oral sumatriptan for the acute treatment of migraine: evaluation of three dosage strengths

This randomized, double-blind, parallel-group, placebo-controlled study evaluated the efficacy and tolerability of oral sumatriptan (Imitrex tablets) in 259 migraineurs. In the clinic, patients received oral sumatriptan 25 mg, 50 mg, or 100 mg, or placebo for the treatment of a migraine attack. The results indicate that by 2 hours post-dose, 50 to 56% of patients treated with any of the three doses, compared with 26% of patients treated with placebo, achieved relief of headache (p < 0.05 for each sumatriptan group vs placebo). By 4 hours postdose, 68 to 71% of sumatriptan-treated patients, compared with 38% of placebo-treated patients, achieved relief of headache (p < 0.05 for each sumatriptan group vs placebo). Oral sumatriptan was similarly effective at relieving nausea and photophobia and at reducing clinical disability. The pattern and incidence of adverse events did not differ between treatment groups. All doses--25 mg, 50 mg, and 100 mg--of sumatriptan were effective and generally well tolerated. Dosing should be individualized according to the needs of the patient.

Publication characteristics of family practice faculty nominated for academic promotion

A survey of family practice department chairmen identified 74 faculty who were nominated for promotion during the 1980-81 academic year; 72 percent had medical degrees, 18 percent had academic doctorates, and 11 percent held other degrees. In each professorial rank those promoted had twice as many publications as those not promoted. Successful and unsuccessful candidates also differed noticeably in the median number of journal publications per year spent on the tenure track. These norms are descriptive, not prescriptive. As the discipline develops academically, promotion characteristics are likely to change.
