Tongue piercing. The new "rusty nail"?

BACKGROUND: Cephalic tetanus is a rare form of the tetanus caused primarily by wounds or other infectious processes involving the head and neck. This condition frequently progresses to the generalized form of tetanus with the attendant risks and complications. METHODS: A case report of a young female who developed an unusual form of tetanus after a tongue piercing is presented here. We discuss this disorder as it applies to the contemporary caregiver with a focus on its presentation and recognition. RESULTS: A delay in diagnosis of 13 days from presentation occurred. The patient had a slow, uneventful but incomplete recovery course. She never developed significant airway compromise, nor did she demonstrate any evidence of hemodynamic instability but continued to have right facial weakness up to 6 months after discharge. CONCLUSIONS: A few factors were identified that contributed to the significant delay in diagnosis. The unusual nature of the disease and a lowered index of suspicion on the part of the initial caregivers were probably the major causes. Fortunately, no major adverse sequelae resulted from the delay. However, if this case heralds the onset of a rise in the incidence of tetanus, early recognition and diagnosis would seem essential to avoid much of the morbidity and mortality associated with the disease.     

Alveolar capillary dysplasia. Report of a case of prolonged life without extracorporeal membrane oxygenation (ECMO) and review of the literature

We describe an unusual infant with the diagnosis of alveolar capillary dysplasia who had a relatively prolonged life without extracorporeal membrane oxygenation (ECMO). We have used this case as a springboard for a thorough review of the literature. This was a full-term female infant who presented with a picture of persistent pulmonary hypertension of the newborn. She was treated as such, with various ventilatory modes, alkalinizing agents, surfactant therapy, tolazoline, prostacyclin and nitric oxide. Because of the prolonged clinical course the possibility of alveolar capillary dysplasia was raised. The parents refused ECMO. Despite all efforts she progressively deteriorated and died at 22 days of age. Macro- and microscopic examination of the lung at autopsy were diagnostic of alveolar capillary dysplasia. A detailed review of 39 cases published in the literature with comments regarding incidence, etiology, pathophysiology, clinical picture, diagnosis and treatment is presented.     

Apoptosis and p53 in inverting papilloma of the sinonasal tract

The objective of this study was to identify apoptotic bodies and p53 positivity in inverting papilloma lesions to study these two as biomarkers in premalignant lesions. Archival specimens of 15 patients with inverting papilloma between the years 1992 and 1995 were retrieved. In situ end labeling technique was used to identify apoptotic bodies. Immunohistochemistry was used to detect p53 in the same specimens. The clinical course was evaluated conducting a retrospective chart review in these patients. Compared to normal epithelium, inverting papilloma lesions had a greater proportion of apoptotic bodies, which was nearly statistically significant (average 0.506/100 cells for inverting papilloma compared with 0.1/100 cells for the normal surrounding tissue). Four cases of inverting papilloma were p53 positive. There was, however, no association between p53 positive staining and the apoptotic rate. The minimum follow-up for patients was 2 years. All had a uniformly good clinical outcome with only one patient who was p53 positive showing concurrent squamous cell carcinoma. We concluded that inverting papilloma contained a higher average number of apoptotic bodies compared with normal surrounding sinonasal tissue. This showed a trend toward a positive between the apoptotic rate and premalignancy, suggesting both increased cellular proliferation and increased cell death may occur in such lesions. In this study p53 did not show a positive association with the apoptotic rate, suggesting that p53 may not be directly involved in the apoptotic regulatory pathway in inverting papillomas.     

Efficacy of antimicrobial treatment in non-dysenteric persistent diarrhoea in a community setting

Objectives : To determine the efficacy of antimicrobial treatment in non-dysenteric persistent diarrhoea in a community setting. Methods : In this double-blind field trial, 156 children aged 4 36 months with persistent diarrhoea not associated with Giardia lamblia infestation seeking treatment in a community outpatient clinic, were randomized to receive a combination of nalidixic acid and metronidazole, metronidazole alone, or placebo for 7 days. Results : In comparison with placebo, metronidazole treatment did not result in a significant reduction in the mean post-enrolment diarrhoeal duration and stool frequency, increase in the proportion of patients recovered by days 3, 5 and 7 of treatment, and increase in weight gain at days 7 and 14. Comparing the combination of nalidixic acid and metronidazole with metronidazole alone, 17.5% more children treated with the combination recovered by day 3 of treatment ( p = 0.08) and the mean stool frequency ascertained on day 7 for the previous 24 h was 26.8% less in them ( p = 0.05). The weight gains at days 7 and 14 were similar in the two groups. Conclusions : These findings indicate that metronidazole offers no therapeutic benefit in persistent diarrhoea not associated with Giardia lamblia and nalidixic acid has only a modest clinical benefit, which is not substantial enough to warrant its routine use.     

RNA interference targeting of A1 receptor-overexpressing breast carcinoma cells leads to diminished rates of cell proliferation and induction of apoptosis

To determine if A1 adenosine receptors mediate breast tumorigenesis, we evaluated A1 receptor expression in human tumor cell lines and human primary breast tumor tissues using both quantitative RT-PCR and Western blot analysis. A1 receptor mRNA expression is upregulated in all breast tumor cell lines examined (n=7) compared to normal mammary epithelial cells/cell lines (n=3) as determined by quantitative RT-PCR analysis. Western blot analysis indicates that protein expression of A1 adenosine receptor is higher in 15 (62.5%) of 24 human primary breast tumor tissues than in matched normal breast tissue. To explore its cellular function, the A1 adenosine receptor was depleted by small interfering RNA (siRNA) in MDA-MB-468 human breast tumor cells. Depletion of A1 receptors in MDA-MB-468 breast tumor cells attenuated both cell growth and cell proliferation as measured by cell number counts and [(14)C]-thymidine incorporation, respectively. Cell cycle analysis indicated that depletion of A1 receptors by siRNA impairs G(1) checkpoint, leading to marked accumulation of cells in G(2)/M phase, in agreement with the inhibitory effect on cell proliferation. Further supporting this finding, synchronization studies of Hela cells in various cell cycle phases suggest that A1 receptor expression is suppressed in G(2)/M cells and depletion of A1 receptor expression by siRNA produced differential expression of several key cell cycle regulators, i.e., accumulation of the cyclin-dependent kinase inhibitor p27 with concomitant reduction of CDK4 and cyclin E proteins. In addition to the impact on cell cycle progression, depletion of A1 receptors by siRNA results in substantial cell death and apoptosis as determined by FACS analysis and annexin V staining method. Together these findings suggest that the A1 adenosine receptor may contribute to tumor cell growth and survival in breast tumor cells.     

Management of suspected scaphoid fractures in accident and emergency departments--time for new guidelines

INTRODUCTION: The objectives of this work were to assess the clinical knowledge of clinicians in the accident and emergency (A&E) departments in England & Wales and evaluate the current trend for the acute management of radiologically normal, but clinically suspected, fractures of the scaphoid. SUBJECTS AND METHODS: We conducted a telephone survey on 146 A&E senior house officers (SHOs) in 50 different hospitals. This survey assessed the clinicians'' experience, their clinical and radiological diagnostic methods, and their initial treatment of suspected scaphoid fractures. RESULTS: The majority (55.8%) of SHOs performed only one clinical test to diagnose suspected scaphoid fractures. Overall, 41% were unable to cite the number of the radiographic views taken and only 10% of departments have direct access to further radiological investigation. There is wide variation in the early treatment of this injury, with the scaphoid cast used most commonly (46%). The majority of SHOs (89%) were unable to describe the features of immobilisation. The mean follow-up period was 10 days, and 53% of cases were followed-up by the senior staff in A&E. Of SHOs, 54% were not aware of any local guidelines for the management of suspected scaphoid fractures in their departments, and 92% were not aware of the existence of the 1992 British Association for Accident and Emergency Medicine (BAEM) guidelines. CONCLUSIONS: The clinical knowledge and the management of suspected scaphoid fractures in A&E are unsatisfactory. We, therefore, suggest that the dissemination of up-to-date guidelines could help to educate clinicians to provide better care to the patients.     

Management of simultaneously ingested and aspirated foreign bodies in an infant

This report describes the management of a 7-month-old baby who aspirated one and ingested two paper pins at a time. Bronchoscopic removal was done for aspirated pin and ingested pins were observed for spontaneous passage in stool, which occurred in 48 hours without any untoward incidence.     

Fungal keratitis due to fusarium solani

A young man presented with swelling, congestion and lacrimation of right eye for one week. On examination, he had corneal ulcer. Corneal scrapings on lactophenol cotton blue stain revealed fungal hyphae. Culture on Sabouraud agar yielded Fusarium solani after 48 hours. Patient was treated with ketoconazole and miconazole and responded well.     

Sirenomelia (Mermaid baby)

Sirenomelia is a rare anomaly that rarely occurs as an isolated lesion. Several theories have been proposed regarding the etiopathogenesis. In this communication, we report a case of sirenomelia. Our patient was referred to hospital at the age of four hours. On examination, fusion of both lower limbs with hook shaped appendage, attached distally, absent genitalia and absent anal orifice was found. Spine was deficient in sacral region. Upper torso looked normal. Baby also had frothing from mouth. Abdomen was non-distended. Feeding tube no.10 was tried to pass through mouth, which got obstructed at the level of upper esophagus that suggested oesophageal atresia. The skeletogram revealed absence of pelvic bones, sacral agenesis, absent fibulae and fracture of both femora. The patient died at the age of 12 hours.
