Abstract
This study aimed at investigating differences in heat generation and bone architecture following four different implant site preparation techniques: compressive osteotomes, conventional drills, osseodensification (OD mode with osseodensification drills), and piezoelectric systems. Porcine rib bones were used as a model for implant surgery. Thermocouples were employed to measure temperature changes, and micro-CT to assess the bone architecture. The primary stability and insertion torque values of the implants placed in the differently prepared sites were assessed. The temperature changes were higher with Piezo. The average primary stability using the ISQ scale was the greatest for drills (76.17 ± 0.90) and the lowest for osteotomes (71.50 ± 11.09). Insertion torque was significantly higher with the osseodensification method (71.67 ± 7.99 Ncm) in comparison to drills, osteotomes, and piezo. Osteotomes showed the highest bone to implant contact percentage (39.83 ± 3.14%) and average trabecular number (2.02 ± 0.21 per mm), while drills exhibited the lowest (30.73 ± 1.65%; 1.37 ± 0.34 per mm). Total implant site bone volume was the highest with osseodensification (37.26 ± 4.13mm3) and the lowest for osteotomes (33.84 ± 3.84mm3). Statistical analysis showed a high primary stability and decrease in temperature during implant site preparation with osseodensification technique. The results support the use of osseodensification technique for implant site preparation.

Abstract
SETTING Antiretroviral treatment (ART) Centre in Tumkur district of Karnataka State, India. There is no published information about pre-ART loss to follow-up from India. OBJECTIVE To assess the proportion lost to follow-up (defined as not visiting the ART Centre within 1 year of registration) and associated socio-demographic and immunological variables. DESIGN Retrospective cohort study involving a review of medical records of adult HIV-infected persons (aged ⩾15 years) registered in pre-ART care during January 2010-June 2012. RESULTS Of 3238 patients registered, 2519 (78%) were eligible for ART, while 719 (22%) were not. Four of the latter were transferred out; the remaining 715 individuals were enrolled in pre-ART care, of whom 290 (41%) were lost to follow-up. Factors associated with loss to follow-up on multivariate analysis included age group ⩾45 years, low educational level, not being married, World Health Organization Stage III or IV and rural residence. CONCLUSION About four in 10 individuals in pre-ART care were lost to follow-up within 1 year of registration. This needs urgent attention. Routine cohort analysis in the national programme should include those in pre-ART care to enable improved review, monitoring and supervision. Further qualitative research to ascertain reasons for loss to follow-up is required to design future interventions.

Abstract
This paper describes a significant biotechnological advancement by creating a minimalist serum-free defined system to co-culture rat mammalian nerve and muscle cells in order to form functional neuromuscular junctions. To date, all the known in vitro nerve and muscle co-culture models use serum containing media; and while functional neuromuscular junctions (NMJ) are described, they failed to detail or quantify the minimum factors needed to recreate the NMJ in vitro. In this work, we demonstrate the development of a defined motoneuron and muscle co-culture system resulting in the formation of NMJs including: 1) a new culture technique, 2) a novel serum-free medium formulation and 3) a synthetic self-assembled monolayer (SAM) substrate N-1 [3-(trimethoxysilyl) propyl] diethylenetriamine (DETA). We characterized the culture by morphology, immunocytochemistry, electrophysiology and videography. This model system provides a better understanding of the minimal growth factor and substrate interactions necessary for NMJ formation and provides a basic system that can be utilized for nerve-muscle tissue engineering, regenerative medicine and development of limb prosthetics.

Abstract
Reductions in circulating estradiol concentrations could be implicated in the pathogenesis of steroid-induced osteoporosis (SIOP) in men. We assessed serum estradiol and adrenal androgens (dehydroepiandrosterone sulfate [DHEAS] and androstenedione) in 77 men (group A: idiopathic osteoporosis [IOP], n = 38, aged [mean +/- SD] 57.7 +/- 12.1 years; group B: SIOP, n = 39, aged 55.3 +/- 13.1 years). We also studied the relationship between bone mineral density (BMD) and serum estradiol in the group of men with SIOP. In group B, we observed a higher prevalence of low serum testosterone concentrations (<9.0 nmol/L) (P =.0052), which was significantly correlated with steroid dosage (r = -0.42, P =.0089) and estradiol concentrations (r = 0.42, P =.012). There was a significant positive association between BMD at the lumbar spine and serum estradiol (P =.004) in the men with SIOP (group B). A high proportion of subjects had low serum estradiol concentrations (<48 pmol/L) in both groups (group A: 44.7 %, group B: 36 %). Serum adrenal androgens concentrations were also significantly suppressed in group B (serum androstenedione-group A: 4.99 +/- 1.8; Group B: 2.1 +/- 1.6 nmol/L; P =.0001). Serum DHEAS was undetectable in 59% of patients in group B versus 6% in group A (P =.001). Reductions in androstenedione also correlated with steroid dosage (r = -0.35, P =.01). In conclusion, the data show that adrenal androgens synthesis is markedly suppressed in men with SIOP. The clinical relevance of this finding remains to be determined. This study also shows a positive association between serum estradiol and BMD and a high prevalence of low serum estradiol in men with SIOP. Low serum estradiol may contribute to bone loss in men with SIOP.

Abstract
OBJECTIVE To examine dose-response relationships regarding the efficiency of gas exchange and hemodynamic function during high-frequency oscillation and partial liquid ventilation (HFO-PLV) of the perfluorocarbon (PFC)-treated lung in a model of acute lung injury. SETTING An animal research laboratory in a university medical center. DESIGN A prospective, randomized study comparing animals receiving varying doses (0, 5, 15, and 20 mL/kg) of perflubron during high-frequency oscillatory ventilation (HFOV) with mean airway pressure (Paw) optimized to achieve a minimal percutaneous oxygen saturation (Spo2). SUBJECTS Nineteen healthy swine (mean weight 28.9 kg) with saline lavage-induced acute lung injury. METHODS Animals were treated with repetitive saline lavage to achieve a uniform degree of acute lung injury (Spo2 < or =90% on an Fio2 of 1.0). After lung injury, subjects were converted to HFOV, and lung volume was optimized. HFO-PLV was initiated by instillation of perflubron at a rate of 0.5 mL.kg-1.min-1 to achieve total doses of 5, 15, and 20 mL/kg. After PFC dosing, the only experimental manipulation consisted of adjustment of Paw to achieve an Spo2 of 90% +/- 2% with Fio2 of 0.6. Gas exchange, hemodynamic variables, and pulmonary mechanics data were collected over a 1-hr period. Five control animals were not dosed with perflubron and remained on HFOV for the 1-hr period of data collection. MEASUREMENTS AND MAIN RESULTS After lung volume recruitment with HFOV, the initiation of HFO-PLV was best tolerated with the two lower doses in our protocol. There were essentially no changes in Paco2 or pH between groups over the dosing interval. After dosing, analysis of variance demonstrated a PFC dose-dependent effect for oxygenation index (p =.01) only; the lowest oxygenation index was found in the 15 mL/kg group (p =.01). In the 15 mL/kg group, the Paw decreased steadily from 20.6 +/- 3.4 cm H2O at the end of dosing to 18.0 +/- 4.9 cm H2O at 60 mins. The Pao2 increased from 113 +/- 51 torr (15.06 +/- 6.79 kPa) to 134 +/- 49 torr (17.86 +/- 6.53 kPa) during this period and was associated with a decreasing oxygenation index (from 11.4 +/- 2.0 to 9.3 +/- 1.5). The cardiac index and pulmonary vascular resistance did not change significantly during the dosing period and were relatively stable after the completion of dosing. CONCLUSIONS The combination of HFOV and perflubron administration was well tolerated hemodynamically and was not associated with deterioration of gas exchange during dosing. Our data suggest that the optimal dose of perflubron to achieve the lowest oxygenation index during HFO-PLV is between 5 and 15 mL/kg. The combination of HFOV and perflubron administration is a novel strategy in the treatment of acute lung injury that shows some promise and merits additional investigation. We hope in future studies to address the histopathologic effects of varying perflubron doses during HFOV in a long-term study of the lung-protective effects of HFO-PLV.

Abstract
A rare case of Cerebral Chromomycosis caused by chromogenic fungus Cladosporium trichoides in a 35 year old male with classical presentation of cerebral abscess is being presented. The case report lays emphasis on the histological diagnosis of chromogenic fungus in the wall of the abscess cavity, surgically removed from a well delineated circumscribed lesion in the frontal lobe of the cerebrum. The causative fungus could be detected even in unstained paraffin sections. The diagnosis could be made only after surgical removal and histopathological examination. The mycological culture could not be made as the material was received in formaldehyde fixative. The unique features of the case is its recurrence free uneventful survival five years after surgical excision. This is probably the fifth reported case of cerebral chromomycosis from India and first of its type from arid zone of Rajasthan.

Abstract
OBJECTIVE Severe hypoglycemia may impair medial temporal-mediated cognitive skills, such as the ability to recall past events explicitly (delayed declarative memory). The objective of this study was to determine whether delayed declarative memory deficits are present in a group of diabetic children with an increased risk of severe hypoglycemia. RESEARCH DESIGN AND METHODS Nondiabetic children (n = 16) and children with type 1 diabetes who had been randomly assigned to either intensive (IT) (n = 13) or conventional (CT) (n = 12) diabetes therapy at the time of diagnosis participated in the study. All episodes of severe hypoglycemia were prospectively ascertained. All children were tested on memory tasks that have been closely linked to medial temporal functioning and on reaction time measures. RESULTS Our results demonstrated that the IT group had a threefold higher rate of severe hypoglycemia, performed less accurately on a spatial declarative memory task, and performed more slowly, but not less accurately, on a pattern recognition task than did the CT group or control subjects. In addition, both groups of type 1 diabetic children were significantly impaired on a motor speed task compared with their nondiabetic peers. CONCLUSIONS These results indicate a selective relative memory impairment associated with IT that is consistent with the effects of severe hypoglycemia and medial temporal damage or dysfunction. If larger prospective studies determine that severe hypoglycemia is the mediating factor for this memory impairment, extreme caution in imposing overly strict standards for glucose control in young patients with type 1 diabetes would be indicated because of the increased risk of hypoglycemia associated with IT regimens.

Abstract
Previous studies of the neuropsychological consequences of insulin dependent diabetes mellitus (IDDM) have had mixed and often contradictory results, possibly due to the heterogeneity of the samples and neuropsychological measures, and a lack of specific hypotheses. In order to address this problem, we focused on the effect of severe hypoglycemia on memory functioning in a relatively homogeneous sample of childhood-onset IDDM patients. Given the deleterious effects of hypoglycemia on medial temporal lobe structures (e.g., hippocampus) and the relationship between medial temporal damage and declarative memory functioning, we hypothesized that those patients who had experienced severe hypoglycemia would demonstrate impaired declarative memory and spared nondeclarative memory functioning. Results of the study were generally consistent with this hypothesis, although some impact of hypoglycemia was observed on perceptual priming ability.

Abstract
Erythromycin, a motilin receptor agonist has been shown to have prokinetic effects on the upper gastrointestinal tract and gallbladder. Colonic effects of the drug are controversial, and it is debated whether human colon contains motilin receptors. In this study we evaluated the effects of erythromycin on colonic transit and stool frequency in 11 patients with idiopathic constipation over a 1-month period in an open study. The dose used was 1 g/day for two weeks followed by 500 mg/day for another two weeks. The mean (SE) total and segmental colonic transit was measured before and seven days after therapy in seven of these patients. A daily record of stool frequency was maintained in all 11 patients. Erythromycin shortened the total colonic transit from 86.2 (14.6) to 44.8 (8.99) hr (P < 0.01); however, segmental transit studies revealed a significant effect (P < 0.01) only in the right colon and rectosigmoid region. No significant side effects were observed with short-term therapy. These preliminary results suggest that erythromycin is of therapeutic value in patients with idiopathic constipation.

Abstract
In order to investigate the relationship between Helicobacter pylori infection of the gastric mucosa and mucosal changes in portal hypertension, gastric fundic and antral biopsies were obtained from 66 patients with portal hypertension and 49 controls with non-ulcer dyspepsia (NUD). Gastric mucosa from portal hypertensive patients exhibited typical vascular dilatation and congestion, while mild dilatation of lamina propria blood vessels was not uncommon in NUD patients with histological evidence of gastritis. Colonization of the gastric mucosa by H. pylori infection was significantly less in portal hypertension (51.5%) compared to controls (75.5%; P < 0.01). The difference was more apparent in patients with marked vascular dilatation (18.8% colonization) compared to patients with minimal vascular dilatation (66.7%). H. pylori infection was significantly associated with active superficial gastritis (P < 0.001), and with atrophic gastritis (P < 0.001), in both study groups. H. pylori-negative superficial gastritis was significantly more common in portal hypertension (25/66 patients) than in controls (7/49; P < 0.05). H. pylori infection was not more common in patients who had undergone repeated sclerotherapy. The results suggest that the gastric mucosa of portal hypertension does not provide a hospitable environment for H. pylori colonization, particularly when mucosal congestion is marked. H. pylori infection does not add significantly to the gastropathy of portal hypertension.

Abstract
Transrectal instillation of water is a recently described technique for improved sonological imaging of the lumen and wall of the colon. In order to assess the accuracy of this technique, termed colonic sonography (CS), in the detection of abnormalities of the large bowel, 100 consecutive patients were subjected to colonic sonography and the results were compared with the results of colonoscopy and surgery. The technique showed a sensitivity of 91% for the detection of colonic tuberculosis, 89% for ulcerative colitis and 83% for colonic cancers. Small mucosal ulcers, polyps less than 7 mm in diameter and the changes of non-specific colitis were not detected. Sonography displayed the entire colon more consistently than colonoscopy. The extent and extra-colonic spread of disease were better appreciated. The procedure was not adversely influenced by the presence of faecal material within the colon and was well tolerated. Colonic sonography is a promising new technique for detecting significant colonic pathology and merits further comparison with existing modalities.

Abstract
Thirty-two children under 3 yr of age with extrahepatic portal vein obstruction were treated with endoscopic sclerotherapy. The group consisted of 22 males and 10 females, with a mean age of 1.96 yr (range 7 months to 3 yr). The procedure was well tolerated by all after premedication with intravenous diazepam. Esophageal varices were eradicated in all children after 4.45 sessions (+/- 1.12). Follow-up clinical and endoscopic evaluations have been carried out over a period of 9 months to 4 yr (mean 3.5 yr) after the patients were put on a sclerotherapy program. There was a significant reduction in number of bleeding episodes (60 vs. 8), mean blood transfusion requirement (2.19 vs. 0.31), and bleeding risk factor (0.09 vs. 0.008). There were a few minor conditions, such as transient dysphagia and esophageal ulcerations, in 14 patients (43.75%), which later responded to medical treatment. Perisclerotherapy bleeding, seen in six patients (18.7%), responded to repeat sclerotherapy. Recurrence of varices was encountered in two patients (6.25%); these were eradicated after reinstitution of sclerotherapy. Endoscopic sclerotherapy is the treatment of choice in patients of extrahepatic portal vein obstruction who are below 3 yr of age.

Abstract
In order to test the postulate that post-hypothermic damage may be caused by protease activation, the effect of the administration of aprotinin on hypothermic mortality was investigated in anaesthetized rabbits. A group of 6 animals received 40.000 KIU aprotinin intravenously prior to the induction of hypothermia by surface cooling and this was followed by a further 35.000 KIU each hour for 5 h. The animals were cooled to 29 degrees C and then rewarmed. A control group received equal volumes of physiological saline. The aprotinin treated animals survived, whereas all the control group died within 7 days, 5 of them within 24 h. The haemodynamic, biochemical and haematological changes in the two groups are reported.

Abstract
Some effects of Org GC 94 (1,3,4,14b-tetrahydro-2,7-dimethyl-2H-dibenzo[b,f]pyrazino[1,2-d][1,4]oxazepine maleate) on human platelets have been investigated. Without pretreatment with ADP, 5-HT-induced aggregation of humam platets was completely inhibited by 2.5 x 10(-8) M of Org GC 94. Aggregation triggered by noradrenaline (2.5 x 10(-5) M) and uptake of 5-HT by human platelets were inhibited only at the high concentrations of 10(-5) and 10(-4) M of Org GC 94 respectively. Up to millimolar concentrations, Org GC 94 did not liberate lactate dehydrogenase from human platelets. Org GC 94 did not block the oxidative deamination of benzylamine by human platelet rich plasma up to 2.5 x 10(-4) M.
