Abstract
One factor limiting the therapeutic efficacy of cord blood (CB) hematopoietic progenitor cell (HPC) transplantation is the low cell dose of the graft. This is associated with an increased incidence of delayed or failed engraftment. Cell dose can be increased and the efficacy of CB transplantation potentially improved, by ex vivo CB expansion before transplantation. Two ex vivo CB expansion techniques were compared: (1) CD133+ selection followed by ex vivo liquid culture and (2) co-culture of unmanipulated CB with bone-marrow-derived mesenchymal stem cells (MSCs). Ex vivo culture was performed in medium supplemented with granulocyte colony-stimulating factor, stem cell factor and either thrombopoietin or megakaryocyte growth and differentiation factor. Expansion was followed by measuring total nucleated cell (TNC), CD133+ and CD34+ cell, colony-forming unit and cobblestone area-forming cell output. When compared to liquid culture, CB-MSC co-culture (i) required less cell manipulation resulting in less initial HPC loss and (ii) markedly improved TNC and HPC output. CB-MSC co-culture therefore holds promise for improving engraftment kinetics in CB transplant recipients.

Abstract
BACKGROUND Treatment of vitiligo is a challenge. Steroids are known to be effective but are associated with serious adverse effects. Many uncontrolled studies have shown calcipotriol to be a promising therapeutic modality in vitiligo. OBJECTIVE To conduct a randomized trial to evaluate the effect of topical calcipotriol ointment (0.005%) and betamethasone dipropionate (0.05%) cream, given alone or in combination, in treatment of localized vitiligo. METHODS Forty-nine patients with vitiligo affecting 5% of their skin were recruited. Patients were randomized into three groups. Group I patients were treated with betamethasone dipropionate (0.05%) cream twice daily. Group II patients were treated with calcipotriol ointment (0.005%) twice daily, and group III with betamethasone dipropionate (0.05%) in the morning and calcipotriol (0.005%) in the evening. RESULTS Forty-five patients completed the study period of 3 months with 15 patients in each group. No patient achieved excellent (> 75%) pigmentation. Marked (50% to 75%) repigmentation was observed in 2 (13.3%), 1 (6.7%) and 4 (26.7%) patients in groups I, II and III, respectively. Moderate (25-50%) repigmentation was observed in 7 (46.7%), 5 (33.3%) and 7 (46.7%) patients in groups I, II and III, respectively. Patients with < 25% pigmentation were termed as minimal pigmentation or no response. The mean time for initial pigmentation to appear was 9.04 +/- 2.0 weeks in group I, 10.18 +/- 1.6 weeks in group II and 5.17 +/- 2.4 weeks in group III (P < 0.01). The acquired pigmentation in the lesions was more stable in group III as compared with patients in groups II and I (P < 0.01). Side-effects in the form of atrophy and lesional burning sensations were more common in group I when compared with groups II and III (P < 0.05). CONCLUSION Combined therapy appeared to give a significantly faster onset of repigmentation along with better stability of the achieved pigmentation and with lesser number of side-effects.

Abstract
BACKGROUND The new antifungal triazoles itraconazole and fluconazole have revolutionized the treatment of pityriasis versicolor. Both drugs have shown promising results in different dose schedules. OBJECTIVE To compare the efficacy and safety of single oral dose treatment with fluconazole versus itraconazole in patients with pityriasis versicolor. METHODS A total of 40 patients with pityriasis versicolor were allocated randomly to group A and group B. A single dose of fluconazole (400 mg) or itraconazole (400 mg) was given orally to group A or group B patients, respectively. Patients were assessed mycologically by KOH and culture. Culture was done from lesional and perilesional skin to quantify growth and to observe the effect of these drugs and the persistence/reappearance of the fungus in relation to relapse at 2 and 8 weeks. Relapse was defined as reappearance or worsening of clinical signs and symptoms or positive KOH/culture after initial improvement. RESULTS Thirteen (65%) patients in the fluconazole group and 4 (20%) patients in the itraconazole group became culture negative at the end of 8 weeks. Relapse was found to be higher in the itraconazole group compared to the fluconazole group (60 vs. 35%). A direct correlation was found between the relapse rate and positivity of perilesional skin for Malassezia furfur. CONCLUSION In the same dosing, fluconazole was found to be more effective than itraconazole; however, both drugs were found to be safe.

Abstract
A retrospective study of bacterial isolates from the wounds of patients admitted to burns unit, was undertaken at Guru Tegh Bahadur Hospital, University College of Medical Sciences, Delhi, India, over a period of 5 years between July 1997 and April 2002. The study compared the results obtained with the previous 5 years data (June 1993-June 1997) from the same unit to determine the changing patterns and emerging trends of bacterial isolates and their antimicrobial susceptibilities. Pseudomonas species (31%) and Staphylococcus aureus (22%) were the most common pathogens followed by Klebsiella species (19%). Multi-drug resistant (MDR) Acinetobacter species (9%) have emerged as an important nosocomial pathogen in our burn unit. Most of the gram-negative isolates obtained were found to be multi-drug resistant and 61% of the tested isolates were extended spectrum beta-lactamase (ESBL) producers. Concomitant resistance to penicillin and aminoglycosides was observed in 61% of Enterococcus fecalis isolates. When compared with the results of previous 5 years (June 1993-June 1997) Pseudomonas spp. was still the commonest pathogen in the burns unit. However, isolation of this organism and other gram-negative organisms has decreased in comparison to previous years. The incidence of antimicrobial resistance has markedly increased over the past years resulting in limitation of therapeutic options.

Abstract
BACKGROUND Vitiligo, a common pigmentary disorder, is recognized to be associated with a high psychiatric morbidity, yet compared to other dermatological disorders like leprosy, psoriasis, etc., it has not been subjected to detailed evaluation of its psychological consequences. The data from the developing countries on this aspect in particular is meager. METHODS One hundred and thirteen cases with vitiligo were evaluated along with 55 healthy controls comparable for sociodemographic profile and matched on attitude to appearance scale. Clinical details, impact of illness, associated dysfunction and psychological morbidity were additionally assessed. RESULTS Twenty-eight patients with vitiligo were found to have psychiatric morbidity, a clinic prevalence rate of 25% (95% confidence interval 20.3-29.3%). The majority of the cases had a diagnosis of adjustment disorder. Psychiatric morbidity was significantly correlated with dysfunction arising out of illness. CONCLUSIONS Vitiligo is associated with high psychiatric morbidity. There is a need to develop cross-cultural database on psychosocial aspects and psychiatric morbidity associated with vitiligo.

Abstract
Blood pressure is affected by situational anxiety, such as the white coat effect. We hypothesised that blood pressure would also be affected by anticipation of a blood test. Volunteer subjects were recruited on the campus of Birmingham University. Subjects were randomly assigned to intervention and control groups. After a period of rest, three seated blood pressure measurements were taken at 1-min intervals using an electronic sphygmomanometer. Between the second and third measurements subjects in the intervention group were told that a blood test would be carried out after the last measurement. No blood test was carried out. Three blood pressure measurements were made in all 213 randomised subjects. Analysis was by intention-to-treat. In the control group mean systolic and diastolic blood pressure fell in successive measurements. Between the second and third measurements mean systolic blood pressure fell by 1.4 mm Hg in the control group and rose by 2.6 mm Hg in the intervention group (difference 4.0 mm Hg, P < 0.0001). A rise in diastolic blood pressure between the second and third measurements did not reach statistical significance. It was concluded that anticipation of a blood test affects measured systolic blood pressure in volunteers. The practice of taking blood tests at the same time as measuring blood pressure may potentially bias estimations of blood pressure.

Abstract
AIM To test the staining potential of a novel liposomal dithranol gel on different types of fabrics and compare it with the only commercially available dithranol preparation in India, Derobin. METHODS Pure cotton, pure polyester and four blends of the two fabrics were tested for staining and washability. RESULTS Both products showed the least staining and spreading on pure cotton with progressively worse stains as the proportion of polyester in the fabric increased. When compared with each other the liposomal dithranol gel showed markedly lighter staining than Derobin on all fabrics. It also washed off completely with water whereas the Derobin stains could not be washed off, even with detergent. CONCLUSION The liposomal gel due to its superior staining properties may potentially increase the acceptability of dithranol amongst psoriasis patients.

Abstract
OBJECTIVE To evaluate dimethylsulphoxide (DMSO) as a topical therapeutic agent for the treatment of two major variants of primary, localized, cutaneous amyloidosis -- macular amyloidosis (MA) and papular/lichen amyloidosis (LA) -- using a monocentric, open, prospective trial. METHODS A total of 25 patients with histopathologically proven cutaneous amyloidosis - MA, LA and BA (biphasic amyloidosis) (13 MA, seven LA, five BA) were requested to undertake a once daily application of either 50% or 100% DMSO for 12 weeks. Progress was regularly assessed with a scoring system for pruritus, pigmentation and papules. RESULTS In 17 (68%) cases, the scores for pruritus decreased but never completely disappeared in any of the patients. Lightening of the pigmentation was noted in only six (24%) cases and the scores for the papules were decreased in only two out of 12 (16.6%) patients. Post-treatment skin biopsies did not reveal a reduction/disappearance of the amyloid deposits. In the follow-up period, the relapse rate was 100%. CONCLUSION DMSO does not have an anti-pruritic effect or amyloid-dissolving properties. As the results are partial and transient, it is concluded that DMSO is not a satisfactory treatment for cutaneous amyloidosis.

Abstract
Hydroxyurea is an anti-tumour agent most commonly used to treat chronic myeloproliferative disorders in doses up to 4 g per day. Dermatological adverse effects reported so far have been observed predominantly in these patients. As we are treating selected psoriasis patients with low dose hydroxyurea we attempted to define the spectrum and chronology of dermatological adverse effects in this group of patients prospectively. Of the 29 evaluable patients, 19 (65.5%) developed a mucocutaneous adverse reaction after a mean duration of 6.4 weeks of treatment. Pigmentation of nails, skin or mucosa was the most common observation and was seen in 17 (58.6%) patients. Other less common findings were xerosis, diffuse alopecia, oedema of the legs, oral ulcers and actinic psoriasis. Adverse effects subsided in 11 (57.9%) patients during a mean follow up of 18 weeks. Three hitherto unreported side-effects - scleral pigmentation, acquired ichthyosis and pigmentation of lunula of the nails - were noted. This first study of dermatological adverse effects of hydroxyurea therapy on Asian psoriatic patients reveals several new findings. Pigmentation of skin, nails and mucosa appears to be very common and occurs early. Serious dermatological side-effects probably do not occur with low dose (up to 1.5 g per day) hydroxyurea in patients with psoriasis.

Abstract
BACKGROUND There is an acute paucity of second-line systemic agents for the treatment of extensive chronic plaque psoriasis (CPP). Recent studies using hydroxyurea in patients with HIV infection and sickle cell anemia have rekindled interest in this old drug and have provided more data regarding safety and dosage. OBJECTIVE We wanted to test the efficacy and tolerability of hydroxyurea in patients with extensive CPP who had to discontinue first-line oral agents for any reason. METHODS The study was a prospective nonrandomized series. Thirty-one patients, including 26 with prior history of systemic antipsoriatic therapy were given hydroxyurea 1-1.5 g per day for a median duration of 36 weeks. They were followed up for a mean period of 36.1 +/- 13.8 weeks. RESULTS Almost 75% of the patients showed an adequate response (35% reduction in Psoriasis Area and Severity Index at or before 8 weeks) with over half showing more than 70% reduction in PASI score. All adverse effects were mild and reversible and none of the patients required cessation of therapy. CONCLUSION Hydroxyurea is an effective, very safe but relatively slower acting alternative for patients with extensive CPP over the short-to-medium term.

Abstract
Pilar leiomyomas are usually multiple and are commonly found on the extensor aspects of the arm, trunk, and face. They are rarely distributed in a linear fashion or seem to follow a dermatome. We report a case of painful, unilateral, zosteriform cutaneous leiomyoma in a 25-year-old housewife. Histopathology revealed interlacing smooth muscle bundles arising from arrector pili muscles. Nifedipine (10 mg) twice daily was remarkably effective in diminishing the pain in our patient.

Abstract
Cytotoxic activity of non-major histocompatibility complex-restricted (CD56+) (NMHC) killer cells and cell surface marker expression of peripheral blood mononuclear cells were determined before and after spaceflight. Ten astronauts (9 men, 1 woman) from two space shuttle missions (9- and 10-day duration) participated in the study. Blood samples were collected 10 days before launch, within 3 h after landing, and 3 days after landing. All peripheral blood mononuclear cell preparations were cryopreserved and analyzed simultaneously in a 4-h cytotoxicity (51)Cr release assay using K562 target cells. NMHC killer cell lytic activity was normalized per 1,000 CD56+ cells. When all 10 subjects were considered as one study group, NMHC killer cell numbers did not change significantly during the three sampling periods, but at landing lytic activity had decreased by approximately 40% (P < 0.05) from preflight values. Nine of ten astronauts had decreased lytic activity immediately after flight. NMHC killer cell cytotoxicity of only three astronauts returned toward preflight values by 3 days after landing. Consistent with decreased NMHC killer cell cytotoxicity, urinary cortisol significantly increased after landing compared with preflight levels. Plasma cortisol and ACTH levels at landing were not significantly different from preflight values. No correlation of changes in NMHC killer cell function or hormone levels with factors such as age, gender, mission, or spaceflight experience was found. After landing, expression of the major lymphocyte surface markers (CD3, CD4, CD8, CD14, CD16, CD56), as determined by flow cytometric analysis, did not show any consistent changes from measurements made before flight.

Abstract
The major non-surgical re-pigmenting therapies for vitiligo include psoralens and corticosteroids, used both topically and systemically. In an attempt to determine the best therapeutic option, we compared the efficacy of various treatment regimens used in our department for the treatment of vitiligo. We report herein our results with six different regimens used in our clinic. Data from five hundred vitiligo patients who attended the pigmentary disorders clinic at the Nehru Hospital, PGI, Chandigarh, was analysed. For the purpose of analysis, patients were arbitrarily divided into two groups based upon the body surface area (BSA) involved: Group A (<10% BSA involved) and B (>10% BSA involved). Group A was further divided into three subgoups of patients depending upon what treatment they received: R-I [topical clobetasol propionate+sun exposure]; R-II [topical psoralen+sun exposure (topical PUVASOL)]; R-III [topical psoralen+UVA (topical PUVA)]. Group B was also subdivided into three subgroups of patients who received: R-IV [oral dexamethasone pulse therapy + sun exposure]; R-V [systemic psoralen + sun exposure (systemic PUVASOL)]; R-VI [systemic psoralen + UVA (systemic PULVA)]. Patients who had undergone, one of the above mentioned regimens and had a regular monthly follow up until total re-pigmentation or for at least one year, whichever was earlier, were included in the final assessment of the therapeutic efficacy of that regimen. At the end of the study in Group A, 207 (89%) patients out of 232 on R-I; 73 (93%) out of 78 on R-II, and 15 (79%) out of 19 patients on R-III showed moderate to excellent re-pigmentation, respectively. In group B, 45 (81%) patients out of 55 on R-IV, 48 (84%) out of 57 on RV, and 22 (84%) patients out of 26 on R-VI showed moderate to excellent re-pigmentation. Statistically, in Group A, R-I & II were significantly better than R-III. However in Group B, there was no significant difference in the responses to R-IV, V, and VI. A positive family history of vitiligo did not seem to affect the response rate. Potent topical steroids used along with sun exposure and topical PUVASOL were the most effective forms of therapy for localised vitiligo. For the generalised form of the disease, we concluded that all the systemic modalities, oral steroids, PUVASOL and PUVA, are equally efficacious over a period of one year. Phototoxic reactions were, however, more common with PUVASOL.

Abstract
A total of 20 bacteriologically positive multibacillary (MB) leprosy patients older than 18 years of age with a bacterial index (BI) of 2+ or greater were given standard World Health Organization multiple drug therapy (MDT-MB) for 12 consecutive months plus four intradermal doses of Mycobacterium w vaccine at 3 monthly intervals (Study group). Twenty age-matched MB patients were given WHO/MDT alone (Control group). The patients of both groups were followed up for 1 year. Improvements in the patients were periodically monitored by clinical (Ramu's score), bacteriological (SSS), histopathological (skin biopsy) and immunological (lepromin conversion) parameters. Study group patients showed more significant improvements in all parameters except for lepromin conversion compared to patients in the Control group. The incidence of type 1 reaction was more in the Study group (30% vs 10%), while the incidence of type 2 reaction was more in the Control group (25% vs 15%). Neuritis associated with reactions was seen more often in the Control group compared to the Study group (20% vs 10%). The addition of Mycobacterium w vaccine as an adjunct to the 1-year WHO/MDT regimen appears to be significantly more beneficial in MB leprosy patients with a high initial BI compared to WHO/MDT given alone. Studies on larger numbers of patients with extended follow up will be in order.

Abstract
This study was a left-right comparison of the efficacy of 0.005% calcipotriol ointment and 5% coal tar ointment in conjunction with sun exposure in 10 patients with stable plaque psoriasis. After four weeks of therapy, the calcipotriol treated site showed a significantly faster fall in PASI compared to the coal tar treated site. At eight weeks, this difference was not significant with both sides showing comparable improvement in lesions, as shown by PASI values. There were no significant side effects from either therapy. We conclude that both calcipotriol and coal tar ointments have comparable efficacy in treating stable plaque psoriasis when used simultaneously with sun exposure, although the initial response to calcipotriol is faster.
