Fatal disseminated adenoviral infection in a renal transplant patient

Immunosuppressed patients are more susceptible to adenoviral infection and carry a significantly higher mortality than immunocompetent patients. Renal transplant patients with adenoviral infection most often present with infection of the kidney and urinary tract within weeks to months of transplant surgery, suggesting reactivation of the latent adenovirus in the immunosuppressed host as the source of infection. We describe the first case of a fatal adenovirus infection after several years of immunosuppression in a kidney transplant patient. Postmortem examination of several tissues, using standard viral culture and polymerase chain reaction, was positive for adenovirus serotype 21. This case is unusual in that the fatal disseminated viral infection occurred after 6 years of immunosuppression, suggesting that the source of adenovirus was a novel infection rather than reactivation of latent infection, or infection from the transplanted tissue. Furthermore, this is the first report of adenovirus type 21 in an immunosuppressed patient.     

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.

Serum Ornithine Carbamoyl Transferase as a Surrogate Marker in Malaria

Ornithine carbamoyl transferase (OCT) activity and other liver function tests were studied in a total of 50 patients of clinical malaria and 15 controls. They were grouped as group I (positive for malarial parasite on peripheral blood smear, n=18), group II (negative for malarial parasite on peripheral blood smear (PBS) but responded to antimalarials, n=17) and group III (peripheral blood smear negative and did not respond to antimalarial therapy, n=15). The mean OCT levels were significantly raised in group I (6.79 ± 1.84 IU/L, p value = 0.006) and group II (5.0 ± 1.15 IU/L, p value = 0.014) as compared to controls (2.5 ± 1.13 IU/L) and returned to normal after treatment In contrast, group III had normal levels except in a case of kala azar and septicemia where OCT levels were high and increased further on treatment. Taking PBS positivity as a gold standard of diagnostic criteria, OCT had a sensitivity of 83% and specificity of 86% with a high positive predictive value of 88% as compared to ALT which had a lower sensitivity of 55% and specificity of 80%. The clinical response rate in PBS negative cases of fever having high OCT level was 83% as compared to 35% in cases with normal OCT level, making OCT a good surrogate marker of malaria. OCT levels could also be of prognostic significance as 2 cases of cerebral malaria had high OCT levels of 11.1 UAL and 10.7 IU/L, respectively.Key Words: Malaria, Ornithine carbamoyl transferase     

Acute Achilles tendon rupture: minimally invasive surgery versus non operative treatment,with immediate full weight bearing. Design of a randomized controlled trial

Background  

We present the design of an open randomized multi-centre study on surgical versus conservative treatment of acute Achilles tendon ruptures. The study is designed to evaluate the effectiveness of conservative treatment in reducing complications when treating acute Achilles tendon rupture.     

Foot Protective System : A Boon to Demining Soldiers

Background

A significant number of soldiers suffer serious injuries or die in the process of demining and a protective device is necessary in such operations.

Methods

All the patients involved in demining operations using the foot protection devices in last one year were analysed.

Results

We received 35 patients, of which only five had limb injuries and 30 had eye injuries. Of the five, three had closed calcaneal fractures and two contusion of foot. No fatality, amputation or compound fracture occured.

Conclusion

Early results after the use of this device during demining operations are encouraging.Key Words: Mine blast injury, Demining, Spider boot     

Facteurs associés aux perdus de vue des patients sous traitement antirétroviral dans un centre de traitement ambulatoire du VIH à Conakry,Guinée

Background

Late or inadequate therapeutic management increases the risk of mortality associated with HIV/AIDS. The aim of this study was to analyze the proportion and factors associated with loss of follow-up in HIV patients who receiving antiretroviral therapy at Conakry.
