[When mothers get cancer: psychological effects on children and needs for prevention].
Children having a parent who suffers from a serious somatic disease are at increased risk for mental health problems. Mainly due to the high prevalence of breast cancer diseases children of mothers with cancer are the most studied subgroup of this risk population. In this review the sequelae of a cancer diagnosis on a patient's female identity with respect to the maternal role are illuminated. Then, children's fears, conflicts and stressors that may be typically associated with maternal cancer are differentiated by age groups from a developmental perspective. In several controlled studies children of cancer patients had increased scores in symptom scales. If there are psychic symptoms, these are likely to manifest themselves as anxiety, depression, psychosomatic complaints or social withdrawal. Adolescent daughters of mothers having cancer had an especially increased risk to develop symptoms. The possible impact of a maternal cancer disease on a developing girl's puberty is discussed. In addition, a case vignette of a nine-year-old daughter of a breast cancer patient illustrates psychotherapeutic procedures in a brief intervention, the goal of which was to facilitate talking about fears between mother and daughter. Perspectives of family oriented mental health prevention in the context of gynaecological care are discussed.

Knowledge about tetanus immunization among doctors in Delhi.
BACKGROUND: In spite of the clear-cut guidelines regarding tetanus immunization, we have observed that tetanus toxoid injection is often given after injury without considering previous immunization status. One of the reasons for this could be that the doctors themselves are not aware of the correct immunization schedules against tetanus. AIMS: 1. To assess the knowledge about tetanus immunization in relation to injuries among doctors. 2. To assess their knowledge about tetanus immunization schedules in children, pregnant women and adults. SETTING AND DESIGN: It was a cross-sectional study conducted in Delhi. MATERIALS AND METHODS: After complete enlisting of all the government allopathic hospitals and dispensaries, a representative sample (including private practitioners from the nearby area of selected dispensaries) of doctors was selected. All the doctors were personally contacted and information was collected through a pre-structured self-administered proforma. STATISTICAL ANALYSIS: Data was analyzed using a computer and wherever applicable Chi-square test/Z test or Fishers' Exact test was applied. RESULTS AND CONCLUSION: As many as 38.3% of doctors favored tetanus toxoid injection after every injury. The correct knowledge of immunization against tetanus in children, pregnant women and adults was 75%, 90.8% and 35.8% respectively. The knowledge regarding when to give boosters was even poorer. The present study showed that doctors had poor knowledge about tetanus immunization that needs to be improved.

The impact of an IEC campaign on tuberculosis awareness and health seeking behaviour in Delhi, India.
OBJECTIVE: To study the impact of an intensive IEC campaign regarding the Revised National Tuberculosis Control Programme launched by the Government of Delhi on awareness generation among the general population and improvement in self-reporting by symptomatic cases in Delhi, India. DESIGN: Cross-sectional study. RESULTS: A pilot study wherein 1008 persons selected by systematic random sampling from the general population and 1012 patients selected from symptomatic cases reporting to DOTS centres were interviewed. Among the general population, 716 (71.0%) had been exposed to one or more IEC message through the media. The core message regarding symptoms, diagnosis, treatment centre and free treatment was recalled correctly by 144 (14.3%), 449 (44.5%), 659 (65.4%) and 900 (89.2%), respectively. In the post IEC period, a significant increase (P < 0.01) was seen in individuals self-reporting with symptoms to DOTS centres: the media message reportedly encouraged 36.3% of these to self-report. Prior to the IEC campaign only 49 (9.8%) patients had chosen a DOTS centre as first source of treatment, which increased significantly (P < 0.0001) to 104 (20.4%) post IEC. CONCLUSION: The IEC campaign launched by the Government of Delhi has been effective in raising awareness and improving self-reporting, but it requires intensification with suitable modification to reach all sectors.

Mental health status of runaway adolescents.
UNLABELLED: There are 47.22 million homeless and runaway adolescents roaming on the streets of our country (Voluntary Health Association of India - VHAI) of which one lakh are in Delhi.1 Very little is known about them, their needs or their experiences. OBJECTIVE: (1). To assess the psychological problems amongst the runaway adolescent boys. (2). To determine possible risk factors. METHODS: This study was cross-sectional in design and done at a child observation home for boys in Delhi. All runaway boys aged 10 to 16 years of age were included in the study. The study was conducted from 15th June to 15th July 2001. A comprehensive schedule consisting of five parts, viz identification data, hopelessness scale for children by Kazdin, Beck depression inventory, Psychological survey questionnaire and RUTTER-B2 scale were used to assess various mental health problems. RESULTS: 20.7% of children were found to have high hopelessness and 8% of children had depression. 2% of children revealed that they had attempted suicide at any point of time in life. Among children with high hopelessness, 3.2% had ever attempted suicide. 8.3% of the depressed children gave history of suicidal attempts. 38% of children gave history of physical abuse, 14.6% of sexual abuse and a large number reported substance abuse. 69.33% were found to have behavioral problems (i.e. scored above the recommended cut off score of 9). 81% of children had antisocial behavior, 7.8% were neurotic and 10.5% remained undifferentiated. CONCLUSION: Runaway adolescents suffer from a wide array of mental health problems and there is a need for a broad based psychosocial intervention programme.

Randomized controlled study of laparoscopic total extraperitoneal versus open Lichtenstein inguinal hernia repair.
BACKGROUND: Whereas open anterior inguinal herniorrhaphy is a time-tested, safe, and well-understood operation with a high success rate, laparoscopic techniques of inguinal hernia repair are fairly recent. Consequently, short- and long-term outcomes are still being evaluated. Few studies have compared laparoscopic extraperitoneal inguinal hernia repair with tension-free open hernia repair. The current study was conducted to compare complications, operative time, postoperative pain, length of hospital stay, and return to work between open tension-free mesh Lichtenstein (open) repair and laparoscopic total extraperitoneal (TEP) repair. METHODS: In a prospective randomized study, open hernia repair was performed in one group (n = 25), and TEP repair using a large mesh was performed in another (n = 25). Then intraoperative and postoperative complications and results were compared. RESULTS: The mean operative time in the TEP group was 75.72 +/- 31.6 min, which was significantly longer than the mean operative time in the open group (54 +/- 15) min (p <0.001). The mean pain scores in the TEP group were 2.64 +/- 1.4 at 12 h and 1.76 +/- 1.4 at 24 h. These scores were significantly lower than the corresponding scores of 3.52 +/- 1.7 (p <0.04) and 2.74 +/- 1.5 (p <0.01) in the open repair group. The mean postoperative analgesic dose was 2.6 +/- 2.3 in the TEP group, which was significantly lower than in the open group 5.76 +/- 3.5 (p <0.001). There was no major complication in either group. The time until return to work was significantly lower in the TEP group (12.8 +/- 7.1) days versus 19.3 +/- 4.3 days; than in the open group (p <0.001). In terms of cosmetics, all 25 patients (100%) in TEP group rated themselves as "highly satisfied," as compared with 7 patients (28%) in the open group (p <0.001). After a mean follow-up period of 13 months (range, 9-18 months), no recurrence was seen in either of the two groups. CONCLUSION: In terms of complications and short-term recurrence, TEP repair is comparable with open repair. Moreover, TEP is significantly less painful in the early postoperative period, leading to earlier ambulation than open repair. Additionally, TEP results in significantly earlier return to work and better cosmetic results. Currently, TEP seems to be a better alternative than the existing open repair, provided the long-term recurrence rates are comparable. Despite the fact that TEP was a new procedure for the surgeon and the study was conducted during the learning phase, the results are comparable with those in the world literature.

Hungry for tobacco: an analysis of the economic impact of tobacco consumption on the poor in Bangladesh.
OBJECTIVE: To investigate the extent of tobacco expenditures in Bangladesh and to compare those costs with potential investment in food and other essential items. DESIGN: Review of available statistics and calculations based thereon. RESULTS: Expenditure on tobacco, particularly cigarettes, represents a major burden for impoverished Bangladeshis. The poorest (household income of less than $24/month) are twice as likely to smoke as the wealthiest (household income of more than $118/month). Average male cigarette smokers spend more than twice as much on cigarettes as per capita expenditure on clothing, housing, health and education combined. The typical poor smoker could easily add over 500 calories to the diet of one or two children with his or her daily tobacco expenditure. An estimated 10.5 million people currently malnourished could have an adequate diet if money on tobacco were spent on food instead. The lives of 350 children could be saved each day. CONCLUSION: Tobacco expenditures exacerbate the effects of poverty and cause significant deterioration in living standards among the poor. This aspect of tobacco use has been largely neglected by those working in poverty and tobacco control. Strong tobacco control measures could have immediate impact on the health of the poor by decreasing tobacco expenditures and thus significantly increasing the resources of the poor. Addressing the issue of tobacco and poverty together could make tobacco control a higher priority for poor countries.

Prognostic significance of apoptosis in squamous cell carcinoma of oral cavity with special reference to TNM stage, histological grade and survival.
Apoptotic count was assessed in 38 cases of squamous cell carcinoma of oral cavity by light microscopy and correlated with TNM stage, histological grade and survival. A direct correlation with the TNM stage (p = 0.0166) and an inverse correlation with the histological grade (p = 0.03) was found, however no correlation was found with the survival. Apoptotic count was significantly different between well and moderately differentiated carcinoma (p = 0.347) and well and poorly differentiated carcinoma (p = 0.0190). Thus apoptotic count may have prognostic value particularly in combination with staging and histological grade.

Hepatitis G virus (HGV) infection in voluntary and commercial blood donors in India.
The prevalence of hepatitis G virus (HGV) has been determined in commercial as well as voluntary blood donors from India by detecting viral RNA genome using reverse transcription polymerase chain reaction (RT-PCR) assay. 45 professional blood donors from private blood banks and 50 healthy controls who opted for voluntary blood donation were recruited for the study. Both the groups were also screened serologically for HBV and HCV infection. The prevalence of HGV in the general population in India was found to be 4% but significantly a higher frequency (46.6%; p<0.001) of HGV was observed in commercial blood donors.

Clinical and immune responses of tuberculosis patients treated with low-dose IL-2 and multidrug therapy.
The immune response to infection with M. tuberculosis depends on cytokine activation of effector cells. We therefore conducted a pilot study of recombinant human interleukin-2 (rhuIL-2) as an adjunct to multidrug therapy (MDT) to evaluate the safety of this approach and to determine whether IL-2 can enhance the cellular immune response in patients with pulmonary tuberculosis (TB). Patients included in this study presented with a wide range of extent and duration of infection, and were grouped into three categories for data analysis: (1) patients with newly diagnosed, acute-stage TB who were just beginning MDT; (2) patients who had received a minimum of 45 days MDT before the start of the study and who had responded to treatment; and (3) patients with multidrug-resistant (MDR) TB who had been on MDT for at least seven months without apparent beneficial clinical response. Twenty patients received 30 days of twice-daily intradermal injections of 12.5 micrograms of IL-2. Patients from all three groups showed improvement of clinical symptoms over the 30-day period of treatment with IL-2 and MDT. Results of direct smear for acid fast bacilli (AFB) demonstrated conversion to sputum-negative following IL-2 and MDT treatment in all newly diagnosed patients and in 5/7 MDR TB patients. (The size of the skin test response to purified protein derivative (PPD) of tuberculin increased during the 30-day IL-2 adjunctive therapy in newly diagnosed patients, but decreased or disappeared in the other two groups of treated patients.) Assays in vitro for phenotype distribution, natural killer (NK) cell activity, frequency of cells proliferating in response to exogenous IL-2, and antigen-induced blastogenesis demonstrated systemic responses to intradermally administered rhuIL-2. Levels of interferon-gamma (IFN-gamma) in plasma, peripheral blood mononuclear cell (PBMC) IFN-gamma mRNA and IFN-gamma mRNA in biopsy of site of skin test response to purified protein derivative (PPD) were highest in those patients with the most acute symptoms at the beginning of the study, and decreased during rhuIL-2 and MDT. IL-2 immunotherapy did not modify levels of mRNA expression for other cytokines. Patients receiving IL-2 did not experience clinical deterioration or significant side effects. These results suggest that IL-2 administration in combination with conventional MDT is safe and may potentiate the antimicrobial cellular immune response to TB.

Multiphasic denaturation of the lambda repressor by urea and its implications for the repressor structure.
Urea denaturation of the lambda repressor has been studied by fluorescence and circular dichroic spectroscopies. Three phases of denaturation could be detected which we have assigned to part of the C-terminal domain, N-terminal domain and subunit dissociation coupled with further denaturation of the rest of the C-terminal domain at increasing urea concentrations. Acrylamide quenching suggests that at least one of the three tryptophan residues of the lambda repressor is in a different environment and its emission maximum is considerably blue-shifted. The transition in low urea concentration (midpoint approximately 2 M) affects the environment of this tryptophan residue, which is located in the C-terminal domain. Removal of the hinge and the N-terminal domain shifts this transition towards even lower urea concentrations, indicating the presence of interaction between hinge on N-terminal and C-terminal domains in the intact repressor.

An operator-induced conformational change in the C-terminal domain of the lambda repressor.
4,4'-bis(1-anilino-8-naphthalenesulfonic acid (Bis-ANS), an environment-sensitive fluorescent probe for hydrophobic region of proteins, binds specifically to the C-terminal domain of lambda repressor. The binding is characterized by positive cooperativity, the magnitude of which is dependent on protein concentration in the concentration range where dimeric repressor aggregates to a tetramer. In this range, positive cooperativity becomes more pronounced at higher protein concentrations. This suggests a preferential binding of Bis-ANS to the dimeric form of the repressor. Binding of single operator OR1 to the N-terminal domain of the repressor causes enhancement of fluorescence of the C-terminal domain bound Bis-ANS. The binding of single operator OR1 also leads to quenching of fluorescence of tryptophan residues, all of which are located in the hinge or the C-terminal domain. Thus two different fluorescent probes indicate an operator-induced conformational change which affects the C-terminal domain. The significance of this conformational change with respect to the function of lambda repressor has been discussed.

Early and long-term results of subclavian angioplasty in aortoarteritis (Takayasu disease): comparison with atherosclerosis.
PURPOSE: To compare the early and long-term outcomes of subclavian artery angioplasty in patients with aortoarteritis and atherosclerosis. METHODS: Sixty-one subclavian artery angioplasties were performed in 55 consecutive patients with aortoarteritis (n = 32) and atherosclerosis (n = 23) between 1986 and 1995. An arch aortogram followed by a selective subclavian artery angiogram was done to profile the site and extent of the lesion, its relation to the vertebral artery, and the distal circulation. Percutaneous transluminal angioplasty (PTA) was performed via the femoral route for 56 stenotic lesions and 5 total occlusions. RESULTS: PTA was successful in 52 (92.8%) stenotic lesions and 3 (60%) total occlusions. Three patients (5.4%) had complications, that could be effectively managed nonsurgically. Compared with atherosclerosis, patients with aortoarteritis were younger (27.4 +/- 9.3 years vs 54.5 +/- 10.5 years; p < 0.001), more often female (75% vs 17.4%; p < 0.001), gangrene was uncommon (0% vs 17.4%; p < 0.05), and diffuse involvement was seen more often (43.8% vs 4.4%; p < 0.001). The luminal diameter stenoses were similar before PTA (88.6 +/- 9.7% vs 89.0 +/- 9.1%; p = NS). Higher balloon inflation pressure was required to dilate the lesions of aortoarteritis (9.9 +/- 4.6 ATM vs 5.5 +/- 1.0 ATM; p < 0.001). This group had more residual stenosis (15.5 +/- 12.4% vs 8.3 +/- 9.4%; p < 0.05) after PTA. There were no neurological sequelae, even in PTA of prevertebral lesions. On 3-120 months (mean 43.3 +/- 28.9 months) follow-up of 40 patients, restenosis was more often observed in patients with aortoarteritis, particularly in those with diffuse arterial narrowing. These lesions could be effectively redilated. Clinical symptoms showed marked improvement after successful angioplasty. CONCLUSION: Subclavian PTA is safe and can be performed as effectively in aortoarteritis as in atherosclerosis, with good long-term results. Long-term follow-up shows that it provides good symptomatic relief.

Age trends of sibling resemblance for height, weight and BMI during growth in a mixed longitudinal sample from Sarsuna-Barisha, India.
BACKGROUND: Even though some studies have considered that sibling resemblance remains constant throughout the life cycle, several investigations emphasize the importance of age and its interactions with genetic and environmental factors in determining sibling similarity in several bodily traits. In fact, the study of age changes in familial resemblance is of great importance for the analysis of certain sources of variation observed in growth processes. AIM: The study examined sibling resemblance for height, weight and body mass index (BMI) in a mixed longitudinal sample from West Bengal, ages 2-19 years, in order to analyse the variations with age of the sibling resemblance for these phenotypes during growth. SAMPLE AND METHODS: Two hundred and forty-five brothers and 213 sisters from 138 middle-class nuclear families living in a semi-urban area of South Kolkata, India were analysed. The analysis of sibling resemblance was performed through correlations estimated by the maximum-likelihood method. The patterns of different trends of sibling resemblance with age were examined by fitting a cubic non-linear regression to the observed correlations. RESULTS: The results show clear variations with age in the sibling resemblance for the traits height and weight, though to a lesser extent for BMI. In general, we found the highest correlation values during the period of infancy, a remarkable decrease during puberty, and a trend of increase towards the end of the growth cycle. CONCLUSION: The study confirms the effect of age on the degree of similarity among siblings for height, weight and BMI in the sample. The sharp decline of correlation at adolescence can be interpreted in terms of the individual variation in age of reaching the adolescent growth spurt.

Hysterectomy: an analysis of perioperative and post operative complication.
OBJECTIVE: To document peri operative and post operative complication observed after hysterectomy, regardless of route on the operator. MATERIAL AND METHODS: A hospital based prospective study was carried out in department of obstetrics and gynaecology, KMCTH Sinamangal for six months. The study was carried out in patients undergoing hysterectomy who were followed from the time of admission to the time of discharge and two weeks thereafter. And followings were noted--Indication; route of hysterectomy, intraoperative and postoperative morbidities during hospital stay and after two weeks of discharge was noted. RESULT: Total number of hysterectomy carried out was 50. 31 (62%) were Total abdominal hysterectomy, and 19 (38%) were vaginal hysterectomy. Indication for total abdominal hysterectomy were fibroid uterus 12 (24%), DUB 8 (16%), CIN 4 (8%), chronic cervicitis 1 (2%). II U-V prolapse with previous LSCS 1 (2%), endometriosis 1 (2%). Prophylactic for Ca breast 1 (2%), Postmenopausal bleeding 1 (2%). All cases of vaginal hysterectomy were performed for 2nd degree U-V prolapse. Intra operative complication during surgery were two cases of haemorrhage (4%) each in both total abdominal hysterectomy and vaginal hysterectomy. There was one case of bladder injury during abdominal hysterectomy. Postoperative complication noted were febrile morbidity 1 (2%) in abdominal hysterectomy. Urinary tract infection remains the single most common febrile morbidity. There was one case of secondary haemorrhage in both type of hysterectomy. One was managed conservatively and other required laparotomy. There were three (6%) cases of wound infection in abdominal hysterectomy of two which were sanguineous discharge and one was frank pus which required secondary suture.
