Clinical significance of anismus in encopresis

Treatments designed to relieve paradoxical contraction of the anal sphincters during defecation (anismus) have had limited success in children with encopresis. This has raised doubts as to the clinical relevance of this diagnosis in childhood as anorectal dysfunction. Our aim was to determine whether, in patients who had treatment-resistant encopresis, the presence of electromyographic anismus was associated with increased faecal retention. Sixty-eight children with soiling (mean age 8.7 ± 2.06 years) were assessed by clinical examination, abdominal radiography and then with anorectal manometry. Patients with electromyographic anismus (n= 32; 47%) had significantly increased radiographic rectal faecal retention and were significantly less likely to be able to defecate water-filled balloons. There were no significant differences in response to prior therapy, history of primary encopresis, behavioural adjustment or in sociodemographic data. Our results suggest that electromyographic anismus is associated with obstructed defecation and faecal retention.     

Mine Blast Injuries - Our Experience

Background

The sudden increase in incidence and magnitude of mine blast injuries prompted us to highlight the problem and its management.

Methods

The cases of mine blast injuries occurring during mining and demining in a particular geographical area were analysed. Total 27 cases of mine blast injuries occurred during mining or demining operations in a period of 13 months.

Results

Various body regions were involved in the mine blast injuries but the main brunt was borne by feet and legs followed by multiple body regions due to splinters. 14 patients underwent below knee (BK) amputation while 4 patients required through knee (TK) amputations. The effect of blast was so severe that most of the cases required 2 to 5 times wound debridements. The initial aggressive debridement / open stump amputation saved the limb and life of all patients.

Conclusion

A mine blast causes extensive injuries and psychological trauma. Management is needed urgently, surgery is difficult, and amputation is often inevitable. Maximum lives and limbs can be saved with aggressive debridement, repeated inspections and dressings under anaesthesia and definitive closure at optimum time.Key Words: Amputation, Antipersonnel mine, Crush syndrome, Debridements, Mine blast injury, Secondary missiles, Shrapenels     

Prekallikrein-Kallikrein conversion rate as a predictor of contrast material catastrophies

An in vitro is described that attempts to detect patients with a potential for adverse systemic reactions to contrast material. This test involves measuring the rate of conversion of prekallikrein to kallikrein under certain standard conditions. In a preliminary retrospective study, the test could be used to identify such patients with a sensitivity of 88%, a specificity of 82%, and a predictive value of 79%.     

Using Standardized Oral Examinations to Evaluate General Competencies

Emergency medicine residency programs are required by the Accreditation Council for Graduate Medical Education (ACGME) to formally evaluate each resident with oral and written examinations. The Michigan State University Emergency Medicine Residency Program in Lansing conducts monthly standardized oral examinations (SOEs) as part of each resident's evaluation. Recently, the ACGME has advanced six areas, termed "general competencies," that should be acquired during graduate medical education. According to the ACGME, these competencies should be included in the educational process of all residency programs. In promulgating these competencies, the ACGME did not provide examples of core content, strategies for implementation, or methods of evaluation; rather, individual residency programs are required to develop their own methods. The authors describe a modification of an existing SOE strategy that assesses residents' knowledge, skills, experiences, and attitudes as reflected in the general competencies.     

Relationship between mass of the left ventricular myocardium and uric acid metabolic imbalance in patients with arterial hypertension

AIM: To analyse relationships between left ventricular myocardium mass (LVMM) and imbalance of uric acid metabolism in patients with arterial hypertension (AH). MATERIAL AND METHODS: Body mass index, waist/hip circumference index, levels of uric acid in the blood and urine, urinary excretion of albumin, LVMM were estimated in 106 patients with mild and moderate AH (70 males and 36 females, mean age 51 +/- 8.5 years). RESULTS: Hypertensive patients with and without metabolic imbalance of uric acid differ significantly by LVMM index. The latter was higher in metabolic imbalance of uric acid, being the highest if this imbalance combined with microalbuminuria. CONCLUSION: Imbalance of uric acid metabolism in AH patients may indicate affection of both the kidneys and the heart.     

Gamma-knife radiosurgery for trigeminal neuralgia

Gamma knife was installed at the PD Hinduja National Hospital and Medical Research Centre, Mumbai, India, in January 1997. In the first year of gamma-knife radiosurgery to January 1998, we treated 110 patients, of whom six had medically refractory trigeminal neuralgia. Seven treatments were administered to this group of six patients (one had bilateral neuralgia). This report evaluates the effectiveness of radiosurgery treatment in these patients. The median age of the patients was 56 years and there were five males and one female. Following Leksell stereotactic frame fixation, a magnetic resonance imaging scan was done in all. The Leksell gamma plan was used for planning. A radiosurgery dose of 70–80 Gy was delivered to the trigeminal root entry zone, 2–4 mm anterior to the junction of the pons and trigeminal nerve with a single 4 mm collimator helmet. Complete pain relief was achieved in four patients. Two had partial relief. No patient developed any radiosurgery related morbidity during the follow-up period of 5–16 months. Radiosurgery seems to be an effective approach for medically or surgically refractory trigeminal neuralgia.

Ciliary motility at light microscopy: a screening technique for ciliary defects?

To verify whether or not ciliary motility can be reliably assessed by light microscopy alone, we examined the nasal brushings of 53 patients with suspected ciliary dyskinesia and 10 healthy controls. The results of light microscopy were compared with cilia ultrastructure assessed with electron microscopy. Ciliary motility was significantly related with cilia ultrastructure. However, eight cases of lung disease due to bronchiectasis of unknown origin had immotile cilia on light microscopy, but normal ciliary ultrastructure on electron microscopy. Instances of normal and abnormal ultrastructure were detected in one case with motile cilia. There was an 83% agreement between electron microscopy and light microscopy. Sensitivity and specificity of light microscopy were 92% and 80%, respectively. In conclusion, light microscopy evaluation of ciliary motility does not appear to be a reliable screening test for ciliary dyskinesia because it does not quantify ciliary beat activity, which is a criterion for deranged ciliary motion. A complete evaluation of ciliary ultrastructure together with in vivo, if applicable, or in vitro function test (namely, the analysis of ciliary beat frequencies and/or waveform) is required for a definite diagnosis of ciliary dyskinesia.
