Anterior uveitis and congenital fibrosis of the extraocular muscles in a patient with Noonan syndrome

We describe a patient with Noonan syndrome who presented with Human Leukocyte Antigen B27-associated recurrent acute anterior uveitis and manifestations of congenital fibrosis of the extraocular muscles, which has not been reported before.     

Influence of age on iminodipropionitrile-induced vestibular and neurobehavioral toxicities in rats

A direct association between aging and drug-induced dyskinesia has been reported by several investigators. Iminiodipropionitrile (IDPN), a prototype nitrile compound produces a motor syndrome in rodents, which resembles neuroleptic drug induced dyskinesia. In this investigation attempt has been made to study the effect of age on IDPN induced vestibular hair cell degeneration and resulting dyskinetic syndrome. Male Wistar rats aged 3, 6 and 12 weeks received IDPN in the doses of 0, 200 and 400 mg/kg, intraperitoneally for 3 consecutive days. IDPN-induced dyskinesia was assessed using a behavioral testing battery on days 3, 4, 5, 6, 7, 14, 21 and 28. The rats were sacrificed on day 28; temporal bones were excised for vestibular histopathology and sera were collected for measuring the indices of oxidative stress (glutathione and conjugated dienes). IDPN in the dose of 200 mg/kg produced dyskinesia in 12 weeks old rats, but failed to do so in 3 and 6 weeks old rats. The high dose of IDPN (400 mg/kg) caused dyskinesia in all age groups, however, its onset and severity were age-dependent. Older rats showed an early onset and significantly high incidence of dyskinesia as compared to younger rats. The susceptibility of rats to IDPN-induced behavioral deficits was proportional to oxidative stress and degeneration of sensory hair cells in the crista ampullaris.     

Blue spotted bladder--a manifestation of bladder amyloidosis. A case report

Bladder amyloidosis may represent a life-threatening condition, but may also be associated with milder clinical symptoms. Herein, we report two older males with a different type of apparently mild bladder amyloidosis, presenting as the "blue spotted bladder".     

Left atrial appendage perforation with Watchman device implantation: Strategies for surgical repair

Percutaneous occlusion of the left atrial appendage is increasingly being used as an alternative for stroke prevention in patients with non‐valvular atrial fibrillation at high risk of complications from long term anticoagulation. We describe a case of left atrial appendage perforation during Watchman device implantation requiring emergency repair of the left atrium using sternotomy and cardiopulmonary bypass. Technical considerations for surgical decision making are discussed; in hemodynamically unstable patients as well as those at high risk for embolization.

Human leukocyte interferon-α in cream,for the treatment of genital warts in asian women a placebo-controlled,double-blind study

The purpose of this double-blind, placebo-controlled study was to determine and compare the clinical efficacy and tolerance of human leukocyte -interferon (incorporated 2 × 10⁶ IU/g) in hydrophilic cream to cure genital warts. Preselected Asian female patients (n=150) aged 18–40 years (mean 22.5), with the clinical and biopsy-confirmed diagnosis of genital warts (mean 2.64), predominantly flat vaginal condylomas, were randomly allocated to 3 parallel groups. Each patient was given a coded tube containing 80 g placebo/active preparation with a graduated applicator. Patients were instructed to inject 6 g of the either alloted placebo/active cream deep into the vagina thrice a day for 3 consecutive days (group A) or 4 consecutive days (group B) per week, and if not cured the same treatment was extended to 3 more weeks (maximum 4 weeks active treatment). To assess the clinical efficacy patients were examined on a week-to-week basis. A total clearance of warts (biopsy-confirmed) was evaluated as a complete cure. Patients cured during the treatment were spared further treatment and were requested to visit us after 16 weeks for relapse control. As for the remaining patients, empty tubes were collected, and similarly coded replacement tubes were given for further treatment (in total 588 tubes were used). By the end of the treatment 57.2% lesions (227/397) were eliminated in all the groups: 48% patients in group A, 90% patients in group B, and 10% patients in placebo groups taken as completely cured. Of the 150 patients 128 (85.3%) did not complain of any drug-related adverse symptoms. Transitory increase in body temperature (mean 38.4°C), accompanied by headache (14.6%) and generalized itching (6.6%) were the most frequently reported side effects; however, treatment was well tolerated by all the patients, and there were no dropouts. Our findings indicate that clinical efficacy is dose dependent, that is, the results of group B were significantly superior to that of group A (P < 0.05). Of the 49.3% cured patients (74/150) followed up for 6 months (monthly basis) seven had a relapse, and none had reinfection. It is concluded that clinical efficacy of leukocyte interferon-a to cure genital warts is dose dependent. These results further support the view that leukocyte interferon-a incorporated in hydrophilic cream can be considered a reliable, safe, and home-based treatment to cure vulvar and vaginal warts.Abbreviation HPV human papillomavirus     

Brain stem auditory evoked potentials in medical coma

BAEPS are coming up as an important investigatory tool in the hands of present clinicians and have a diagnostic and prognostic significance. The present study was carried on 25 patients. BAEPS were recorded at the time of admission and analysed. Absent BAEPS were associated with high mortality. Abnormal BAEPS were seen in infective and CVA group. Followup BAEPS showed no change in those patients who died.     

Protein kinase C and a calcium-independent phospholipase are required for IgG-mediated phagocytosis by Mono-Mac-6 cells.

Mono-Mac-6 (MM6) human monocytes ingest IgG-opsonized particles better than other human cell lines. We compared the phagocytic signaling pathway in MM6 with human monocytes. MM6 expressed FcgammaRI at levels similar to monocytes, whereas FcRgammaII expression was approximately double. MM6 ingested IgG-opsonized erythrocytes (EIgG) in a calcium-independent manner. Incubation of MM6 with bromoenol lactone, an inhibitor of the phagocytic phospholipase (pPL), coordinately decreased phagocytosis and pPL activity. This inhibition was overcome by exogenous arachidonic acid, suggesting that phagocytosis requires pPL activation and arachidonic acid release. MM6 phagocytosis was inhibited with staurosporine and activated with diacylglycerol, supporting a role for protein kinase C (PKC) in this process. The pPL activators mastoparan and melittin restored phagocytosis to PKC-inhibited cells, suggesting that pPL lies downstream from PKC. These results suggest that the MM6 signal transduction pathway for IgG-mediated phagocytosis is similar to that of monocytes (PKC-->pPL-->arachidonic acid-->phagocytosis). The results are discussed in the context of the finding that MM6 exhibit low phagocytosis relative to monocytes and thus may represent an attractive cell line for molecular manipulation in "recovery of function" studies.
