Googling "Anatomy dissection": Pre-pandemic, pandemic, and current scenario

OBJECTIVES

The present study was proposed to assess if the online search behavior for Anatomy dissection was affected by actual dissection being performed in the labs. The interest in dissection was ascertained and compared between pre-pandemic, pandemic, and current times.

METHODS

Online web search behavior for key terms related to "Anatomy dissection" was noticed worldwide using Google Trends Tool. Relative search volume (RSV) was downloaded for these keywords worldwide using all categories, and web search settings during a period from January 1, 2018, to July 31, 2022.

RESULTS

There was almost a similar google trend for the first three months in years 2018 and 2020, with a slightly lower RSV in March and a noticeable RSV decrease from April onwards in 2020. During the pre-pandemic period, the peak for RSV in the month of May was noticed. These peaks were missing in 2020 and 2021. In May 2022, RSV again increased. The top five countries with the highest search hit for "Anatomy Dissection" web were the Philippines, the United States, Canada, Australia, and India.

CONCLUSIONS

There was lower search trend for "Anatomy dissection" during the pandemic period as compared to pre-pandemic period. The search trends may be associated with the closure of dissection labs and it may be concluded that Anatomy learners search for this term more often, if they are actually performing the dissections. The future integrated multi-country data and analysis from different set-ups about their ways of dissection and labs before and after the pandemic may further clarify.

Metastatic tumors to the pancreas: Balancing clinical impression with cytology findings

Backgrounds/Aims

Metastatic lesions of the pancreas (PMET) account for 1%–5% of all malignant solid pancreatic lesions (SPL). In this study we evaluated the utility of endoscopic ultrasonography with fine needle aspiration (EUS-FNA) in diagnosing PMET.

Methods

Patients who underwent EUS-FNA at a community referral center between 2011–2017 for SPL were identified. Clinical, radiologic, and EUS-FNA features of those with PMET were compared to those with primary solid tumors of the pancreas: pancreatic adenocarcinoma (PDAC) and neuroendocrine tumors (PNET).

Results

A total of 191 patients were diagnosed with solid pancreatic malignancy using EUS-FNA: 156 PDAC, 27 PNET, and eight (4.2%) had PMET. Patients with PMET were less likely to have abdominal pain (25.0% vs. 76.3% vs. 48.2%; p < 0.01) or obstructive jaundice (37.5% vs. 58.3% vs. 0%; p < 0.01) compared to PDAC and PNET. Those with PMET were more likely to have mass lesions with/without biliary or pancreatic ductal dilatations (100% vs. 86.5% vs. 85.2%; p < 0.01) and lower CA19-9 (82.5 ± 43.21 U/mL vs. 4,639.30 ± 11,489.68 U/mL vs. 10.50 ± 10.89 U/mL; p < 0.01) compared to PDAC and PNET. Endosonographic features were similar among all groups. Seven (87.5%) patients with PMET had a personal history of malignancy prior to PMET diagnosis. The primary malignancy was renal cell carcinoma in five PMET.

Conclusions

PMET are exceedingly rare, comprising less than 5% of SLP. Patients with PMET are less likely to present with symptoms and mostly identified by surveillance imaging for the primary malignancy.

Ethnic Minorities and Low Socioeconomic Status Patients With Chronic Liver Disease Are at Greatest Risk of Being Uninsured

Background

Chronic liver disease (CLD) predominantly affects ethnic minorities and socially vulnerable populations, who have high prevalence of risk factors (e.g., suboptimal insurance coverage) predisposing to healthcare disparities. We evaluate prevalence and predictors of uninsured status among CLD adults, and secondarily, how this affects documented immunity or vaccination for hepatitis A virus (HAV) and hepatitis B virus (HBV).

Methods

Using 2011 - 2018 National Health and Nutrition Examination Survey data, self-reported insurance status was determined among adults with CLD. Prevalence of uninsured status was stratified by patient characteristics and evaluated using multivariable logistic regression models. Prevalence of self-reported completion of vaccination as well as laboratory value-based documented immunity to HAV and HBV was stratified by insurance status.

Results

Overall, 19.0% of adults with CLD reported having no insurance, which was highest among individuals of Hispanic ethnicity (33.5%), less than high school education (33.7%), and below poverty status (35.3%). On multivariable analyses, significantly lower odds of having any insurance coverage was observed in men, Hispanics, and individuals with lower education and lower household income. Prevalence of documented immunity or vaccination for HAV was low across all insurance categories, ranging from 46.5% to 54.0%. Prevalence of documented immunity or vaccination for HBV was similarly low across all insurance categories, ranging from 24.3% to 40.8%.

Conclusion

Prevalence of uninsured status among CLD was more than twice the US adult population, and lack of insurance particularly impacted Hispanics and individuals with low education and low household income. Low prevalence of documented immunity or vaccination for HAV and HBV across all insurance categories is concerning.

140. Antibiotic Prophylaxis for Upper Gastrointestinal Bleed in Liver Cirrhosis: Less May Be More

Background

Antibiotics in patients with cirrhosis and upper gastrointestinal bleeding are shown to improve outcomes. Little is known regarding optimum duration of prophylactic antibiotics, with 7 days of therapy generally recommended. Antibiotic duration has not been compared to outcomes in current scientific literature. The goal of our study was to study the effect of shorter antibiotic duration on outcomes.

Methods

This was a retrospective cohort study of patients with cirrhosis presenting with upper GI bleeding at our institute from 2010-2018. Patients were divided into three cohorts based on duration of antibiotic administration: 1-3 days, 4-6 days, and 7 days or more. Rates of infection within 30 days, time to infection, rebleeding and mortality were compared between the three groups. Multivariable analysis was conducted to evaluate independent risk factors for infection.

Results

Medical charts of 943 patients with cirrhosis and upper GI bleed were reviewed. 303 patients did not have concomitant confirmed or suspected infection on presentation, of these 243 patients received antibiotics for prophylaxis and were included for analysis. Seventy-seven patients received antibiotic therapy for 3 days or less, 69 patients for 4-6 days, and 97 patients &gt;6 days. The groups were well matched in demographic & clinical variables. 27 patients developed infections within 30 days of bleed. High MELD score at presentation and presence of ascites were associated with infection within 30 days. Rates of infection were not statistically different between the antibiotic groups (p= 0.78). In the 30 days following GI bleed, pneumonia was the most diagnosed infection (11 patients) followed by UTI (8 patients). Four patients developed spontaneous bacterial peritonitis and 3 were diagnosed with bacteremia. There was no difference in time to infection (p= 0.75), early re-bleeding (p=0.81), late re-bleeding (p= 0.37) and in-hospital mortality (p= 0.94) in the three groups. Six patients developed C. Difficile infection, none of whom were in the short antibiotic group.

Conclusion

Short course of antibiotics for prophylaxis (3 days) appears safe and adequate for prophylaxis in patients with cirrhosis and upper gastrointestinal bleeding if bleeding has abated and there is no active infection.

Cadaverless anatomy: Darkness in the times of pandemic Covid-19

The pandemic Covid-19 is responsible for a major education crisis globally and has a drastic impact on medical training as well. The objective of the present study was to envision the present and future impact of Covid-19 on anatomy learning and research. The virtual education is the only mode of teaching in current scenario. Every anatomist is unlocking technology to deliver best education however understanding of the subject without dissections or other practical teaching aids like bones, specimens, embryology models, microscopic slides etc. is challenging. This approach misses the feel and human visual impacts. Potential educational disruption is felt currently and will be experienced even after the pandemic is over due to scarcity of cadavers. As the body donor may be carrier or died of Covid-19 and there is no proven screening to rule out this infection in donor, so the acceptance of body donations is not advisable for the safety of medical students and health care workers. To conclude, anatomy education is cadaverless currently due to Covid-19 lockdown and it is prophesied that after the pandemic, real cadavers will be replaced by virtual cadavers because of paucity of cadavers. Research in the field of anatomy will also be adversely affected.

Thromboelastography versus standard coagulation testing in the assessment and reversal of coagulopathy among cirrhotics: a systematic review and meta-analysis

The utility of thromboelastography/thromboelastometry currently has unvalidated clinical benefit in the assessment and reversal of coagulopathy among cirrhotic patients as compared to standard coagulation testing. A novel systematic review and meta-analysis was conducted in order to assess pooled outcome data among patients receiving thromboelastography/thromboelastometry as compared to standard coagulation testing. As compared to standard coagulation testing, there was a significant reduction in the number of patients requiring pRBC, platelet, and fresh frozen plasma transfusions among thromboelastography/thromboelastometry group with pooled OR 0.53 (95% CI 0.32-0.85; P = 0.009), 0.29 (95% CI 0.12-0.74; P = 0.009), and 0.19 (95% CI 0.12-0.31; P < 0.00001), respectively. Similarly, there was a significant reduction in number of pRBC, platelet, and fresh frozen plasma units transfused in the thromboelastography/thromboelastometry group with pooled MD -1.53 (95% CI -2.86 to -0.21; P = 0.02), -0.57 (95% CI -1.06 to -0.09; P = 0.02), and -2.71 (95% CI -4.34 to -1.07; P = 0.001), respectively. There were significantly decreased total bleeding events with pooled OR 0.54 (95% CI 0.31-0.94; P = 0.03) and amount of intraoperative bleeding during liver transplantation with pooled MD -1.46 (95% CI -2.49 to -0.44; P = 0.005) in the thromboelastography/thromboelastometry group. Overall, there was no significant difference in mortality between groups with pooled OR 0.91 (95% CI 0.63-1.30; P = 0.60). As compared to standard coagulation testing, a thromboelastography/thromboelastometry-guided approach to the assessment and reversal of cirrhotic coagulopathy improves overall number of patients exposed to blood product transfusions, quantity of transfusions, and bleeding events.

Anatomy of scalenovertebral triangle: A vade mecum for clinicians

OBJECTIVE OF THE STUDY

The thorough anatomical knowledge of scalenovertebral triangle or Triangle of the vertebral artery and its contents is crucial in various neurosurgical procedures such as scalenotomy, stellate ganglion block, direct isolation of proximal vertebral artery and proximal brachial plexus repair.

MATERIAL AND METHOD

Thirty scalenovertebral triangles of known age and sex were dissected. The morphometry of the triangle and stellate ganglion was done. Various relevant distances were measured for topographical location of neurovascular structures especially stellate ganglion and vertebral artery within the triangle.

RESULTS

The mean height and width of the scalenovertebral triangle was 21.7+5.1mm and 19.4+4.4mm respectively. Vertebral artery originated from subclavian artery within the triangle except in one case (left side) where it originated from aortic arch. The mean minimum distance of stellate ganglion from phrenic nerve, scalenus anterior and vertebral origin was 12.6+4.5mm, 12.26+4mm and 2.3+1.3mm respectively.

CONCLUSIONS

The origin and proximal part of vertebral artery may not be present within the scalenovertebral triangle, thus topographic anatomy of the stellate ganglion is also affected and may cause complications during stellate ganglion block. Stellate ganglion is never located in the lateral or upper third of triangle. Occasionally, the phrenic nerve may cross the triangle, making it unsafe during stellate ganglion block.

Evaluating quality of life tools in North American patients with erythropoietic protoporphyria and X-linked protoporphyria

BACKGROUND

Erythropoietic protoporphyria (EPP) and X-linked Protoporphyria (XLP) are rare photodermatoses presenting with severe phototoxicity. Although anecdotally, providers who treat EPP patients acknowledge their life-altering effects, tools that fully capture their impact on quality of life (QoL) are lacking.

METHODS

Adult patients with EPP/XLP were given four validated QoL tools: the Patient Reported Outcomes Measurement Information System 57 (PROMIS-57), the Hospital Anxiety and Depression Scale (HADS), the Illness Perception Questionnaire Revised (IPQR), and an EPP-Specific tool. All patients received the PROMIS-57 while the HADS, IPQR, and EPP-Specific tools were introduced at a later date. Associations between responses and clinical phenotypes were explored.

RESULTS

Two hundred and two patients were included; 193 completed PROMIS-57, 104 completed IPQR, 103 completed HADS, and 107 completed the EPP-Specific tool. The IPQR showed that patients strongly believed EPP/XLP had a negative impact on their lives. Mean scores in anxiety and depression domains of both HADS and PROMIS-57 were normal; however, anxiety scores from HADS were borderline/abnormal in 20% of patients. The EPP-Specific tool revealed a decreased QoL in most patients. The PROMIS-57 showed that 21.8% of patients have clinically significant pain interference. Several tool domains correlated with measures of disease severity, most being from the PROMIS-57.

CONCLUSIONS

Impaired QoL is an important consequence of EPP/XLP. PROMIS-57 was most sensitive in evaluating impaired QoL in EPP/XLP. Further research is needed to compare the effectiveness of it for assessing response to treatment.

Results of a pilot study of isoniazid in patients with erythropoietic protoporphyria

Erythropoietic protoporphyria (EPP), the most common porphyria of childhood and the third most common porphyria of adulthood, is characterized clinically by painful, non-blistering cutaneous photosensitivity. Two distinct inheritance patterns involving mutations affecting genes that encode enzymes of the heme biosynthetic pathway underlie the clinical phenotype. Aminolevulinic acid synthase 2 (ALAS2), the rate limiting enzyme of the heme pathway in the erythron, is a therapeutic target in EPP because inhibiting enzyme function would reduce downstream production of protoporphyrin IX (PPIX), preventing accumulation of the toxic molecule and thereby ameliorating symptoms. Isoniazid (INH) is widely used for treatment of latent and active M. tuberculosis (TB). Sideroblastic anemia is observed in some patients taking INH, and studies have shown that this process is a consequence of inhibition of ALAS2 by INH. Based on these observations, we postulated that INH might have therapeutic activity in patients with EPP. We challenged this hypothesis in a murine model of EPP and showed that, after 4 weeks of treatment with INH, both plasma PPIX and hepatic PPIX were significantly reduced. Next, we tested the effect of INH on patients with EPP. After eight weeks, no significant difference in plasma or red cell PPIX was observed among the 15 patients enrolled in the study. These results demonstrate that while INH can lower PPIX in an animal model of EPP, the standard dose used to treat TB is insufficient to affect levels in humans.

Association of Pretransplant Renal Function With Liver Graft and Patient Survival After Liver Transplantation in Patients With Nonalcoholic Steatohepatitis

Nonalcoholic steatohepatitis (NASH) is one of the top 3 indications for liver transplantation (LT) in Western countries. It is unknown whether renal dysfunction at the time of LT has any effect on post-LT outcomes in recipients with NASH. From the United Network for Organ Sharing-Standard Transplant Analysis and Research data set, we identified 4088 NASH recipients who received deceased donor LT. We divided our recipients a priori into 3 categories: group 1 with estimated glomerular filtration rate (eGFR) <30 mL/minute/1.73 m² at the time of LT and/or received dialysis within 2 weeks preceding LT (n = 937); group 2 with recipients who had eGFR ≥30 mL/minute/1.73 m² and who did not receive renal replacement therapy prior to LT (n = 2812); and group 3 with recipients who underwent simultaneous liver-kidney transplantation (n = 339). We examined the association of pretransplant renal dysfunction with death with a functioning graft, all-cause mortality, and graft loss using competing risk regression and Cox proportional hazards models. The mean ± standard deviation age of the cohort at baseline was 58 ± 8 years, 55% were male, 80% were Caucasian, and average exception Model for End-Stage Liver Disease score was 24 ± 9. The median follow-up period was 5 years (median, 1816 days; interquartile range, 1090-2723 days). Compared with group 1 recipients, group 2 recipients had 19% reduced trend for risk for death with a functioning graft (subhazard ratio [SHR], 0.81; 95% confidence interval [CI], 0.64-1.02) and similar risk for graft loss (SHR, 1.25; 95% CI, 0.59-2.62), whereas group 3 recipients had similar risk for death with a functioning graft (SHR, 1.23; 95% CI, 0.96-1.57) and graft loss (SHR, 0.18; 95% CI, 0.02-1.37) using an adjusted competing risk regression model. In conclusion, recipients with preserved renal function before LT showed a trend toward lower risk of death with a functioning graft compared with SLKT recipients and those with pretransplant severe renal dysfunction in patients with NASH.

Patients with stage 3 compared to stage 4 liver fibrosis have lower frequency of and longer time to liver disease complications

BACKGROUND AND AIMS

Advanced liver fibrosis is an important predictor of liver disease progression and mortality, and current guidelines recommend screening for complications of cirrhosis once patients develop F3 fibrosis. Our study compared liver disease progression and survival in patients with stage 3 (F3) and stage 4 (F4) fibrosis on liver biopsy.

METHODS

Retrospective study of patients with F3 or F4 on liver biopsy followed for development of liver disease complications (variceal bleeding, ascites, and hepatic encephalopathy); hepatocellular carcinoma, and survival (overall and transplant free survival).

RESULTS

Of 2488 patients receiving liver biopsy between 01/02 and 12/12, a total of 294 (171 F3) were analyzed. Over a median follow up period of 3 years, patients with F4 (mean age 53 years, 63% male) compared to F3 (mean age 49 years, 43% male) had higher five year cumulative probability of any decompensation (38% vs. 14%, p<0.0001), including variceal bleed (10% vs. 4%, p = 0.014), ascites (21% vs. 9%, p = 0.0014), and hepatic encephalopathy (14% vs. 5%, p = 0.003). F4 patients also had lower overall 5-year survival (80% vs. 93%, p = 0.003) and transplant free survival (80% vs. 93%, p = 0.002). Probability of hepatocellular carcinoma in 5 years after biopsy was similar between F3 and F4 (1.2% vs. 2%, p = 0.54).

CONCLUSIONS

Compared to F4 stage, patients with F3 fibrosis have decreased risk for development of liver disease complications and better survival. Prospective well designed studies are suggested with large sample size and overcoming the limitations identified in this study, to confirm and validate these findings, as basis for modifying guidelines and recommendations on follow up of patients with advanced fibrosis and stage 3 liver fibrosis.

Acute Alcoholic Hepatitis: Natural History and Predictors of Mortality Using a Multicenter Prospective Study

Objective

To examine the natural history of acute alcoholic hepatitis (AH) and identify predictors of mortality for AH using data from a prospective multicenter observational study.

Participants and Methods

We analyzed data from 164 patients with AH and 131 heavy-drinking controls with no liver disease. Participants underwent clinical/laboratory assessment at baseline and 6 and 12 months after enrollment. Multivariable analyses were conducted to identify variables associated with mortality and examine the association between coffee drinking and risk of AH.

Results

Thirty-six patients with AH died during follow-up, with estimated 30-day, 90-day, 180-day, and 1-year survival of 0.91 (95% CI, 0.87-0.96), 0.85 (95% CI, 0.80-0.91), 0.80 (95% CI, 0.74-0.87), and 0.75 (95% CI, 0.68-0.83), respectively. In the multivariable analysis, higher serum bilirubin level (hazard ratio [HR]=1.059; 95% CI, 1.022-1.089), lower hemoglobin level (HR=1.263; 95% CI, 1.012-1.575), and lower platelet count (HR=1.006; 95% CI, 1.001-1.012) were independently associated with mortality in AH. Compared with controls, fewer patients with AH regularly consumed coffee (20% vs 44%; P<.001), and this association between regular coffee drinking and lower risk of AH persisted after controlling for relevant covariates (odds ratio=0.26; 95% CI, 0.15-0.46). Time-dependent receiver operating characteristic curve analysis revealed that Model for End-Stage Liver Disease; Maddrey Discriminant Function; age, serum bilirubin, international normalized ratio, and serum creatinine; and Child-Pugh scores all provided similar discrimination performance at 30 days (area under the curve=0.73-0.77).

Conclusion

Alcoholic hepatitis remains highly fatal, with 1-year mortality of 25%. Regular coffee consumption was associated with lower risk of AH in heavy drinkers.

Role of nail bed methotrexate injections in isolated nail psoriasis: conventional drug via an unconventional route

Nail psoriasis can be a debilitating condition; however, in patients with isolated nail involvement, the use of toxic systemic therapies such as methotrexate may not be justified. We report on 4 patients (30 involved nails between them), who were treated with injections of methotrexate (0.1 mL of a 25 mg/mL solution) into the nail bed at 3-weekly intervals. Mean baseline Nail Psoriasis Severity Index (NAPSI) was 4.77 (range 2-8, cumulative score 143; n = 30); dropping successively at each visit to 2.43 (range 0-4, cumulative score 73; n = 30) at 15 weeks. The decline in mean NAPSI from 4.87 to 2.17 was statistically significant (P < 0.001; Friedman analysis). Reported adverse effects were pain, injection site pigmentation and nail bed haemorrhage. Administration of specific targeted therapy to the nail bed may help manage nail psoriasis effectively.

Variability in survival of very low birth weight neonates in hospitals of India

This prospective cohort study was conducted to evaluate variability in mortality of very low birth weight (VLBW) neonates during their birth hospitalization in different hospitals of India. A liveborn neonate was eligible for inclusion in the study if it was born or admitted in a participating hospital between 1st January and 31st December 2012 and weighed 1500g or less at birth. Neonates were given clinical care as per standard protocols. Standardized neonatal mortality ratio (SNMR) was calculated as the ratio of the observed mortality to the expected mortality. Expected mortality rate for each unit was calculated by adjusting for various prognostic factors at the time of birth or admission in the participating unit. Among 1345 neonates [mean birth weight: 1168 ± 240g, median gestation: 30wk (IQR: 28-32)] enrolled in the study 199 (14.8%) died before hospital discharge. Although variation in inter-hospital SNMR was statistically insignificant (P 0.49), 95% CI of SNMR of most hospitals was broad reaching level of clinical significance on both sides of line of equivalence. This indicates the need to establish an ongoing quality-improvement collaborative network to identify and adopt clinical practices associated with decreased mortality.

A New Drug Combinatory Effect Prediction Algorithm on the Cancer Cell Based on Gene Expression and Dose-Response Curve

Gene expression data before and after treatment with an individual drug and the IC₂₀ of dose–response data were utilized to predict two drugs' interaction effects on a diffuse large B-cell lymphoma (DLBCL) cancer cell. A novel drug interaction scoring algorithm was developed to account for either synergistic or antagonistic effects between drug combinations. Different core gene selection schemes were investigated, which included the whole gene set, the drug-sensitive gene set, the drug-sensitive minus drug-resistant gene set, and the known drug target gene set. The prediction scores were compared with the observed drug interaction data at 6, 12, and 24 hours with a probability concordance (PC) index. The test result shows the concordance between observed and predicted drug interaction ranking reaches a PC index of 0.605. The scoring reliability and efficiency was further confirmed in five drug interaction studies published in the GEO database.

Subcutaneous mycoses caused by Rhytidhysteron species in an immunocompetent patient

Subcutaneous mycoses are chronic fungal infections of the skin and subcutaneous tissues caused by variety of fungal agents and usually occur following trauma with vegetative matter. We report a case of subcutaneous mycoses caused by rare fungus belonging to the genus Rhytidhysteron, in an immunocompetent male who presented with a subcutaneous nodule on left foot. This unusual species was identified and confirmed by molecular methods.

Cling wrap, an innovative intervention for temperature maintenance and reduction of insensible water loss in very low-birthweight babies nursed under radiant warmers: a randomized, controlled trial

AIM

The value of polythene film ('cling wrap') to improve thermal control and reduce postnatal weight loss in preterm, very low-birthweight babies was investigated.

METHODS

Consecutively born babies with birthweights between 750 and 1500 g were stratified by birthweight (<1250 g, 1251-1500 g) and randomised either to the cling wrap (CW) or no cling wrap (NCW) group. The baby bassinette of the RW was covered with cling wrap up to the level of the neck in the CW group for the 1st 7 days. The primary outcome variables were the incidence of hypothermia (axillary temperature < or = 36 degrees C) after initial stabilisation during the first 7 days and cumulative weight loss (percentage of birthweight) at 48 hours of age.

RESULTS

Of 51 babies, 26 were randomised to the CW and 25 to the NCW group. None of the babies in the CW group developed hypothermia in the 1st 7 days but 36% in the NCW group (p = 0.001) did. Babies who were hypothermic on admission took less time to reach normal temperature in the CW group. Cumulative weight loss in the 1st 48 hours was 5.0 + 5.6% in the CW group and 8.6 + 7.0% in the NCW group (p = 0.06).

CONCLUSION

Use of CW might be a simple method of maintaining temperature in very low-birthweight babies in developing countries.

Myiasis arising in condylomata acuminata: an unusual presentation

Myiasis is infestation of skin, mucosa, orifices or natural cavities of humans or animals by larvae of flying dipterous insects that, at least for a certain period of their life cycle, feed from live or necrotic tissue of the host. The distribution is worldwide with more cases being reported from tropical, subtropical and warm temperate areas. This report describes a rare case of perianal condylomata acuminata complicated with myiasis due to Chrysomya bezziana, seen in the presence of poor hygiene in a tropical country with a high fly population.

Tobacco-alcohol amblyopia: A rare complication of prolonged alcohol abuse

Tobacco-alcohol amblyopia is rare, however, extremely disabling complication seen in patient with alcohol dependence syndrome, which if not addressed properly and at the right time may lead to persisting deficits. We here report a patient of alcohol-dependence syndrome who presented with significant diminution of vision bilaterally in the background of excess alcohol consumption.

Adult onset, hypopigmented solitary mastocytoma: report of two cases

Solitary mastocytoma is known to occur predominantly in children below 2 years of age and onset in adulthood is rare. Lesions are hyperpigmented in the majority of cases owing to the stimulation of melanin synthesis by mast cell growth factor. We hereby report two patients with adult onset solitary mastocytoma presenting as hypopigmented plaque. The first case was a 24-year-old man who presented with a plaque on the back of the neck of 5 years duration. The second case was a 30-year-old man who had a well-defined solitary, oval 3 x 2.5 cm plaque on the nape of the neck. Stroking of lesion resulted in a wheal with flare (Darier's sign) in both cases. Systemic examination was within normal limits in both cases. Histopathology revealed a dense toluidine blue-positive infiltrate of mast cells in the upper dermis in both cases.

Eyelid involvement in disseminated chronic cutaneous lupus erythematosus

Eye involvement in chronic cutaneous lupus erythematosus (CCLE) has been reported infrequently. We describe two cases of disseminated CCLE, a 50-year-old woman and a 45-year-old man, with eyelid involvement and disease duration of 4 and 20 years respectively. The first patient showed an excellent response to chloroquine while there was lack of response in the second patient.

Lepromatous leprosy with bilateral facial nerve palsy and hyperthyroidism

Bilateral lagophthalmos secondary to facial nerve is extremely uncommon. Further, the aetiology in most of these cases is of central origin unlike the peripheral involvement in leprosy. A patient of lepromatous leprosy (LL) may be euthyroid or hypothyroid on account of leprous involvement of the thyroid gland. A case of LL with bilateral lagophthalmos and hyperthyroidism is reported.

Breastfeeding practices and health-seeking behavior for neonatal sickness in a rural community

The aim of the study was to evaluate the knowledge of mothers and grandmothers regarding breastfeeding and health-seeking behavior for neonatal sickness in a rural community. A cross-sectional survey, using a triangulation of qualitative (focus group discussion) and quantitative (structured questionnaire) methods was carried out. Although most of the grandmothers and mothers believed in early feeding within 2 h of delivery, they often administered prelacteal feeds such as ghutti and honey. Colostrum was considered beneficial. Most respondents believed that ghutti, water, or both should be given along with breastmilk. Diluted buffalo milk was the preferred choice if supplementation was required. It was thought that weaning should be introduced after 6 months of life. Mothers preferred to give dalia and khichri as the initial weaning food compared to roti and dal water by grandmothers. Both grandmothers and mothers felt that a baby who was playful and not crying excessively was usually healthy. Most of the respondents described the normal pattern of breathing, feeding, urination, and defecation adequately. Most of the grandmothers and mother's felt that by touching forehead and limbs of baby could reliably assess temperature. Refusal to feed was considered as a marker of a sickness by most grandmothers and mothers. However, they also believed that health-seeking for poor feeding could be delayed for 1 day. Respiratory distress was described by the presence of fast respiration, chest retractions, or noisy breathing. Most respondents did not know how to assess cyanosis or seizures. Jaundice was descried as yellowish discoloration of skin, eyes, and urine. Failure to pass urine for 4-6 h bothered most of the respondents. The first response to illness was home remedies. The choice of healthcare was unqualified village practitioners followed by government hospital. Knowledge regarding desirable breastfeeding practices was inadequate and quite a few inappropriate beliefs were widely prevalent. Although knowledge regarding sickness was present, health-seeking from qualified providers was considerably delayed with most respondents preferring village practitioners to government hospitals.

Scar sarcoidosis in childhood: case report and review of the literature

Sarcoidosis is a rare disease among children, manifesting differently in children below and above 4-5 years of age. Although the exact incidence and prevalence of childhood sarcoidosis is not known, the cutaneous involvement is frequent in both children and adults. Infiltration of old cutaneous scars with sarcoid granuloma in the active phase of disease, known as scar sarcoidosis is one of the uncommon cutaneous manifestations of sarcoidosis. We report a case of scar sarcoidosis in an 11-year-old child along with a brief review of the literature.

Factors associated with sight threatening lesions of leprosy in patients on multidrug therapy

One hundred and six consecutive patients (old and newly diagnosed) attending the leprosy clinic at Guru Teg Bahadur Hospital, Delhi, underwent a detailed ophthalmic examination to identify factors associated with the prevalence of sight threatening lesions of leprosy so as to delineate a sub-group of patients who should continue under active ophthalmic surveillance to prevent blindness. All of them were receiving multidrug therapy as recommended by WHO. Demographic data, systemic parameters and ophthalmic lesions attributable to the disease were endorsed on to a proforma. The data were analysed by chi-square test, discriminant analysis and multivariate regression analysis to isolate factors that could be associated with sight threatening lesions of leprosy. In 106 leprosy patients 212 eyes were examined; sight threatening lesions were found in 37 eyes (17.4%). The comea was involved most commonly (78.3%). The lesions were still present in 15.8% of patients who had completed multidrug therapy. Leprosy related visual impairment was seen in 2.3% eyes and blindness in 0.9% eyes. Factors significantly associated with sight threatening lesions included female gender, multibacillary leprosy, increasing duration of leprosy, thickened corneal nerves, subepithelial punctate corneal opacities and presence of any academic lesion of leprosy. On multivariate and discriminant analysis, female gender, thickened corneal nerves and duration of leprosy > 7 years were significantly associated with sight threatening lesions.

Social and sexual risk factors for bacterial vaginosis

BACKGROUND

A number of sexual and social risk factors for bacterial vaginosis (BV) have been identified. However, many previous studies have used small numbers of patients, or highly selected or convenience samples, or poorly defined populations. This study aims to clarify potential sexual and non-sexual risk factors for BV.

METHODS

Women attending the Sydney Sexual Health Centre with BV, between March 1991 and July 1999, were included. Controls were randomly selected women without BV. Information on the demographics, clinical findings, and sexual and non-sexual risk behaviours were extracted from the clinic database and analysed using SPSS and SAS. A logistic regression model was used to establish which associations with BV persisted.

RESULTS

890 women with BV and 890 controls were studied. Factors that were independently associated with BV were > or =3 male sexual partners in the past 12 months (OR = 1.60, 95% CI: 1.19 to 2.04), at least one female sexual partner in the past 12 months (OR = 2.1, p = 0.003), a past pregnancy (OR = 1.5, p<0.0006), and smoking. In contrast, women with BV were significantly less likely to have used hormonal contraception (OR = 0.60, 95% CI: 0.51 to 0.81) or to have used condoms consistently (OR = 0.5, 95% CI: 0.31 to 0.71) than controls.

CONCLUSION

Our findings may be important for planning a preventive strategy for BV by discouraging smoking and increasing condom use and hormonal contraception among women.

Effect of fortification with human milk fortifier (HMF) and other fortifying agents on the osmolality of preterm breast milk

This study was conducted to test the effect of fortification with human milk fortifier (HMF), low birth weight (LBW) formula and coconut oil, initially and upon subsequent storage, on the osmolality of preterm breast milk. Milk samples (n = 48) were collected from mothers (n = 25) delivered at 34 pounds weeks and fortified with HMF (Lactodex-HMF), LBW formula (Lactodex-LBW) and edible coconut oil. Osmolality was measured before and after fortification and after 6 hours,.The gestation and birth weight (median) was 31 (range 29-32) weeks and 1198 (range 716-1478) grams. The median (range) postnatal age at testing was 15 days (range 3-60 days). There was a significant increase in osmolality of breast milk (302.3 +/- l.82) after addition of HMF (392.9 +/- 3.01) and LBW formula (390.5 +/- 2.4). There was no change in osmolality with addition of coconut oil (304 +/- 1.6). There was no further change in the osmolality after 6 hours of storage at 4 degrees C.

Involvement of genitofemoral nerve with genital lesions in lepromatous leprosy

The case of a male patient diagnosed to have lepromatous leprosy with type 2 reaction on multibacillary multidrug therapy, with unusual, widespread involvement of genitalia in the form of plaque and nodules of leprosy over scrotum and perimeatal region of glans, necrotic lesions of erythema nodosum leprosum over scrotum, neuritis of genital branch of genitofemoral nerve bilaterally, and azoospermia, is reported.

Rowell's syndrome and associated antiphospholipid syndrome

We report a 27-year-old primigravida with systemic lupus erythematosus, erythema multiforme-like lesions and a peculiar immunological pattern consisting of antinuclear antibody (speckled pattern) and rheumatoid factor, an association known as Rowell's syndrome. She also had a probable antiphospholipid syndrome as evidenced by the presence of a prolonged activated partial thromboplastin time, kaolin clotting time and thrombocytopenia.

Treatment of Schamberg's disease with pentoxifylline--therapeutic trial

Twenty patients with Schamberg's disease were started on pentoxifylline (400 mg once daily) for a period of 8 weeks. Improvement was assessed at 2 weekly intervals by two observers independently and graded as mild (< 25%, moderate (25-50%) and marked (>50%). Marked improvement was observed in 10/20(50%) patients. We conclude that pentoxifylline should be considered as first line therapy in all patients with Schamberg's disease.
