Exacerbation of Partial Seizures and Onset of Nonepileptic Myoclonus with Carbamazepine

A child had two to three generalized tonic-clonic (GTC) seizures per week unresponsive to phenobarbital (PB) and valproate (VPA). Interictal EEG demonstrated left occipital spikes. When carbamazepine (CBZ) therapy was started, he developed very frequent (4-6/day) complex partial seizures (CPS) characterized on ictal EEG by focal right temporal lobe discharges. The seizure exacerbation, which was associated with development of nonepileptic, multifocal myoclonus, resolved 24 h after CBZ was discontinued. The exacerbation occurred with therapeutic CBZ serum levels, but may have been related to the toxic levels of carbamazepine-10, 11-epoxide (CBZE).     

Ewing's tumour of rib presenting as chest mass

Immunoglobulin concentration in gingival tissue of type 2 diabetic patients with periodontitis.

BACKGROUND: Diabetes mellitus is considered as a risk factor for the initiation and progression of periodontal disease. The diabetic patients often exhibit decreased immune response and increased susceptibility to infection. In the present study, a quantitative estimation of the gingival tissue immunoglobulin concentrations in diabetic and non diabetic subjects with periodontitis was assessed and compared with that of clinically healthy gingiva. METHOD: 40 gingival tissue samples obtained from 20 diabetic (Type 2) and 20 non-diabetic subjects were subjected to quantitative estimation of immunoglobulins G, A, and M. The data thus obtained were compared to the level of immunoglobulin found in clinically healthy gingiva. RESULTS: The IgG and IgA level in the tissues of both diabetic and non-diabetic subjects with periodontitis were found to be significantly higher than that of healthy subjects. The diabetic group also showed a significantly higher IgG and IgA levels compared to the non-diabetic group with periodontitis. CONCLUSION: These findings support the concept that the humoral immune response plays an important role in the pathogenesis of periodontal disease in diabetics. The significantly higher levels of immunoglobulin in the gingival tissues might be a protective mechanism against the increased bacterial challenge in diabetic subjects.     

Amelioration of hypertrophic cardiomyopathy using nonsurgical septal ablation in a cirrhotic patient prior to liver transplantation.

A 53-year-old male with hepatitis C cirrhosis, who had been refused liver transplantation because of hypertrophic cardiomyopathy (HC), underwent nonsurgical septal ablation using alcohol with resolution of his ventricular outflow obstruction. This patient was able to subsequently undergo a successful deceased donor liver transplantation. This is the first reported case of alcohol induced septal ablation being performed in a cirrhotic patient with HC. Such nonsurgical procedures may be attractive in cirrhotic patients who are refused access to liver transplantation because of high surgical risk.     

A study of 10 cases of velopharyngeal incompetence treated by flap pharyngoplasty

Velopharyngeal incompetence (VPI) is a condition of incomplete closure of V.P. port area, normally formed by velum and posterior pharyngeal watt. The condition primarily results in various types of speech defects, which form- the main complaint of the patient. We have studied 10 cases of VPI due to various causes and the speech improvement obtained by flap pharyngoplasty procedures. The results have been evaluated with a follow-up of six months. Highly encouraging results only indicate a more frequent need to undertake such surgery without any hesitation if the ENT surgeon is familiar with and has an adequate exposure to this simple and effective procedure.     

Menstrual-Linked Asthma

This study was conducted to determine the occurrence of menstrual-linked asthma (MLA) in India in 100 consecutive female asthmatics in the reproductive age group. The patients were required to respond to a questionnaire concerning the relationship between their asthma and the menstrual cycle. Twenty-three patients had subjective perception of deterioration in symptoms of asthma in relation to the menstrual cycle. Ten patients from both groups were also required to maintain a daily peak expiratory flow rate (PEFR) diary for 2 consecutive menstrual cycles. The mean total duration of illness in patients with MLA was significantly longer than in patients without cyclic exacerbation. Cough and breathlessness were also significantly more severe as was the disease. This was evidenced by the more frequent emergency room visits and hospitalizations in these patients. Menstrual-linked worsening of asthma was most common in the premenstrual week (17 patients). In 8 of these 17 patients, this phenomenon continued to occur during the menstrual week also. Interestingly, 1 patient complained of deterioration of asthma 2 days after menstruation was over. Such an observation is yet to be recorded. Fourteen patients reported an increase in symptoms with almost every cycle while 3 had worsening related to specific season only. Sixteen patients often required extra medication during the premenstrual and/or menstrual weeks. A significant association was also observed between severity of premenstrual syndrome and MLA. The mean PEFR values over 2 cycles revealed a significant fall in the morning as well as evening values in the premenstrual and menstrual weeks as compared to the midcycle week in patients with MLA. This fall was maximal in the premenstrual week. Such a fall was not observed in asthmatics without menstrual exacerbation of symptoms. MLA was detected in about a fourth of the female asthmatics in India and it appears to represent a more severe form of the disease. This study also documented that MLA was associated with an increase in airway resistance and was not simply due to an increased perception of symptoms during the premenstrual or menstrual weeks.     

Thiamine deficiency in utero alters response to ethanol in adulthood

To determine whether prenatal thiamine deficiency, a frequent concomitant of alcoholism, reduces the response to ethanol during adulthood in the rat as does ethanol exposure in utero (Abel et al. 1981), pregnant Sprague-Dawley rats received either control or thiamine deficient diets together with daily injections of the thiamine antagonist pyrithiamine. At 7 months of age, male offspring were exposed to precisely regulated ethanol vapor concentrations in an inhalation chamber for 24 h and blood ethanol concentrations (BECs) and ethanol-induced intoxication were determined. Prenatally thiamine deficient rats and controls were indistinguishable in terms of appearance, body and liver weights, and the ratios of liver to body weight and brain to liver weight. However, total body water was significantly greater, and BECs and behavioral impairment were decreased, in the experimental rats. These findings indicate that prenatal thiamine deprivation is associated with reduced pharmacologic effect of ethanol as a result of increases in its volume of distribution and rate of metabolism.
