Colour, nutritional composition and antioxidant properties of dehydrated carrot (Daucus carota var. sativus) using solar drying techniques and pretreatments.

Carrot is a seasonal perishable tuberous root vegetable which presents a preservation challenge owing to its elevated moisture content. Recently, carrot processing has received more attention because of its many health-promoting qualities and the reduction of postharvest losses in a cost-effective safe way. This study was designed to sort out the effective solar drying technique including pre-treatment that would retain the color and quality characteristics of dehydrated carrot. Carrot slices were subjected to dry using open sun drying (D1), solar drying long chimney (D2), solar drying short chimney (D3) and box solar drying (D4) techniques with the pretreatments of ascorbic acid 1 % (C3), citric acid 5 % (C4), potassium metabisulfite 1 % (C5) and potassium sodium tartrate 0.3 % (C6) before drying. Drying characteristics, nutritional attributes, phytochemicals and antioxidant of the dehydrated carrot samples were compared with the fresh sample and untreated (control) sample. Results showed that D4 was a good drying method to preserve nutritional quality with good appearance. Among the pretreatments, C5 and C4 resulted improved nutritional quality retention, enhanced visual acceptability and enriched antioxidant activities. PCA (Principal Component Analysis) and correlation matrix revealed that D4 with C5 retained the maximum amount of vitamin, minerals, total phenolic content, antioxidant and admirable dehydrated carrot color by inactivating enzymatic reaction. Therefore, box solar drying with potassium metabisulfite pretreatment would be very promising for functional carrot drying retaining acceptable color and nutrition composition.

Potential candidacy for thrombolysis among ischemic stroke patients presenting to Khyber Teaching Hospital, Peshawar.

Objectives: To determine the number of ischemic stroke patients presenting to a tertiary care hospital that are potential candidates for thrombolysis. Methods: This need analysis study was conducted on one hundred consecutive ischemic stroke patients during the last quarter of 2022 at the Department of Medicine, Khyber Teaching Hospital, Peshawar. The Arrival National Institute of Health Stroke Scale (NIH Stroke Scale) was calculated for all suspected stroke patients after a detailed history and clinical examination. An urgent non-contrast-enhanced CT scan brain was carried out. Patients were included in the study group after intra-cranial bleed was excluded on imaging. Results: The majority (43%) of the patients (male and female) fell in the age group 51-60 years. Fifty-nine (59%) patients had hypertension as a co-morbid condition; 49% had diabetes mellitus while the remaining percentages were constituted by other risk factors. Fifty-seven (57%) patients presented with NIH Stroke Scale between 5-15; 25% had NIH Stroke Scale greater than or equal to 21. Forty-one (41%) patients having daytime (8 am to 8 pm) strokes presented within 4.5 hours of stroke onset to the hospital while 31% of patients having nighttime strokes (8 pm to 8 am) presented within 4.5 hours of stroke onset to the hospital. Conclusion: The majority (72%) of ischemic stroke patients reached the hospital facility within 4.5 hours of stroke onset. These patients can be benefited from thrombolysis leading to improved outcomes if available in that particular health facility.

Effect of Ramadan Fasting on Body Weight and Body Mass Index (BMI) in Public Sector Undergraduate Medical Students of Peshawar.

Objective: To determine the effects of fasting on weight and eventually on Body Mass Index (BMI) in medical students of a Public Sector Medical College. Methods: It was a prospective analytical study conducted in a Public Sector Medical College in Peshawar City from 28th March to 20th May 2022 (1443 Hijri). Convenience Sampling was used and 115 students (58 male and 57 female) of 1st Year MBBS to Final Year MBBS were enrolled. Four readings of weight were taken, one before, two during, and one after Ramadan. A well-structured self-administered questionnaire was used to inquire about basic demographic characteristics, sleep patterns during Ramadan and normal routine, and family history of obesity. The collected data were analyzed through SPSS software and a repeated measures ANOVA test was used for drawing statistical conclusions. Results: A slight increase in the mean weight was observed during the second week of Ramadan while a loss of 0.4 kg occurred during the fourth week of Ramadan, F (1, 81) = 1777.55; p < 0.0001. The same pattern was observed for BMI, F (1, 81) = 2705.18; p < 0.0001. However, the weight and the BMI were regained in two to three weeks following Ramadan. Conclusion: Ramadan offers a non-hazardous way of weight loss. Further studies across different geographical locations with larger sample sizes should be conducted to identify and quantify the association between weight and fasting and also to identify potential confounders.

Thrombosis of the Vein of Trolard: An Atypical Presentation of Protein C Deficiency.

Cerebral venous thrombosis refers to complete or partial occlusion of the cerebral sinus/es or the feeding cortical veins, resulting in secondary effects of vascular congestion and focal or generalized neurological deficits. One of the important causes of venous thromboembolism is inherited thrombophilia. Our case is of a 34-year-old male with no previous comorbidity who presented to the emergency department with complaints of sudden onset left-sided weakness, seizures, and loss of consciousness for one day. Thrombosis of the vein of Trolard was diagnosed based on magnetic resonance venography (MRV) film. His MRI with MRV revealed an attenuated caliber of the vein of Trolard along with abnormal signal intensity in the right fronto-parietal region and the right falcine location. He was managed with intravenous medication, including levetiracetam and topiramate. Once the diagnosis was established, he was commenced on subcutaneous Enoxaparin. Consequently, his GCS improved from 6/15 to 15/15 within the first 24 hours, and he could move his limbs on the day of discharge without any significant disability.

Eosinopenia in Patients With Typhoid Fever: A Case-Control Study.

Background and objectives Salmonella typhi is involved in one of the most prevalent infectious diseases of South East Asia, typhoid fever, but diagnostic tests cannot be performed regularly in developing countries. The objective of the study is to determine the association of eosinopenia with culture or serology-proven typhoid fever in patients, to determine the association of leukopenia with culture or serology-proven typhoid fever in patients and to determine independent predictors of eosinopenia. Methods This case-control study, done at Fauji Foundation Hospital, Pakistan, included patients with symptoms suggestive of typhoid fever, culture, or serology positive for typhoid fever and excluded patients who had been previously diagnosed with malaria and dengue hemorrhagic fever. After flagging cultures and serology, the records were viewed for leukocyte counts. Data, including age, gender, and clinical symptoms, were also recorded for analysis. Results Out of 200 participants, 59 participants with diagnosed typhoid fever had eosinopenia. There were 29 participants who had been diagnosed with typhoid fever via culture or serology and had leukopenia. Eosinopenia and leukopenia were more likely to be present in patients with a diagnosis of typhoid (OR: 9.60, 20.00). The independent predictors for eosinopenia were DOT enzyme immunoassay (DOT EIA) positive for Salmonella typhi, culture positive for Salmonella typhi and leukopenia (p<0.05). Conclusion The presence of eosinopenia and features or serology suggestive of typhoid would most likely be associated with cultures being positive and, therefore, might provide an efficient means to begin treatment.

Antisynthetase syndrome presenting as interstitial lung disease: a case report.

BACKGROUND: Antisynthetase syndrome is a relatively uncommon entity, and can be easily missed if not specifically looked for in adults whose initial presentation is with interstitial lung disease. Its presentation with interstitial lung disease alters its prognosis. CASE PRESENTATION: This case report describes a 27-year-old Pakistani, Asian man, a medical student, with no previous comorbidities or significant family history who presented with a 3 months' history of low grade fever and lower respiratory tract infections, associated with exertional dyspnea, arthralgias, and gradual weight loss. During these 3 months, he had received multiple orally administered antibiotics for suspected community-acquired pneumonia. When he presented to us, he was pale and febrile. A chest examination was significant for bi-basal end-inspiratory crackles. Preliminary investigations revealed raised erythrocyte sedimentation rate. High resolution computed tomography of his chest showed fine ground-glass attenuation in posterior basal segments of both lower lobes suggestive of interstitial lung disease. He was started on dexamethasone, to which he responded and showed improvement. However, during the course of events, he developed progressive proximal muscle weakness. Further investigations revealed raised creatinine phosphokinase and lactate dehydrogenase. A thorough autoimmune profile was carried out which showed positive anti-Jo-1 antibodies in high titers. A muscle biopsy was consistent with inflammatory myopathy. Clinical, radiological, serological, and histopathological markers aided in making the definitive diagnosis of antisynthetase syndrome. Antisynthetase syndrome is a variant of polymyositis but with visceral involvement, that is, interstitial lung disease and positive anti-Jo-1 antibodies. Our patient responded very well to glucocorticoids and azathioprine. CONCLUSION: Antisynthetase syndrome is a rare clinical entity which apart from clinical presentation requires specific serological investigations for diagnosis. Concomitant association of interstitial lung disease gives it a guarded prognosis.

Prevalence of the risk factors for QT prolongation and associated drug-drug interactions in a cohort of medical inpatients.

BACKGROUND/PURPOSE: Medical inpatients are at increased risk of QT interval prolongation due to multiple risk actors and QT prolonging drugs. This study aimed to identify the prevalence of risk factors for QT prolongation; QT prolonging medications; associated drug-drug interactions (QT-DDIs); their predictors; and TdP (torsades de pointes) risks of drugs. METHODS: This cohort study was carried out in medical wards of two tertiary hospitals in Khyber Pakhtunkhwa, Pakistan. The QT-DDIs were identified using Micromedex DrugReax® and AZCERT (Arizona Center for Education and Research on Therapeutics) QT drugs lists. AZCERT QT drugs lists were used to identify TdP risks. Logistic regression analysis was performed to identify predictors of QT-DDIs. RESULTS: Total 400 patients were included in this study. The most frequent QT prolonging risk factors included use of ≥1 QT prolonging drugs (74.5%), female gender (55%) and diabetes mellitus (36.3%). Total 487 QT prolonging drugs were identified. According to AZCERT classification, 33.8% of the interacting drugs were included in list-1 (known risk of TdP), 0.9% in list-2 (possible risk of TdP) and 58.8% in list-3 (conditional risk of TdP). The occurrence of QT-DDIs was significantly associated with ≥10 prescribed medications (p = 0.01), chronic liver disease (p = 0.05), chronic obstructive pulmonary disease (p = 0.03), gastroenteritis (p = 0.02), antimicrobials (p < 0.001), antiemetics (p < 0.001) and antinausea (p < 0.001). CONCLUSION: A substantial number of patients were exposed to risk factors for QT prolongation; and QT prolonging drugs such as proton pump inhibitors, antimicrobials and diuretics which may lead to serious outcomes.

Potential drug-drug interactions in outpatient department of a tertiary care hospital in Pakistan: a cross-sectional study.

BACKGROUND: Potential drug-drug interactions (pDDIs) are one of the preventable drug related problems having the risk of serious adverse events or therapeutic failure. In developing countries like Pakistan, this issue remains poorly addressed. The objective of this study was to explore prevalence of pDDIs in the Outpatient Department (OPD) of a tertiary care hospital in Pakistan. The secondary aim was to describe the levels of reported pDDIs and develop a list of widespread clinically relevant interactions. METHODS: Prescriptions of 2400 OPD patients were analyzed for pDDIs through Micromedex Drug-Reax®. Prevalence, severity- and documentation-levels and widespread clinically relevant interactions were reported. RESULTS: Of total 2400 prescriptions, pDDIs were present in 22.3%. Whereas, moderate- and major-pDDIs were found in 377 (15.7%) and 225 (9.4%), respectively. PDDIs were more prevalent in Medicine (9.2%) and Cardiology (2.6%) as compared with other OPD specialties. Total 942 pDDIs were identified, of which, the majority were either moderate- (61.9%) or major-pDDIs (32.1%). Some of the most common interactions were ibuprofen + levofloxacin (n = 50), ciprofloxacin + diclofenac (32), aspirin + atenolol (24), and diclofenac + levofloxacin (19). The potential adverse outcomes of widespread interactions were seizures, bleeding, QT-interval prolongation, arrhythmias, tendon rupture, hypoglycemia/hyperglycemia, serotonin syndrome, drug toxicity, and decreased therapeutic response. CONCLUSIONS: OPD patients were at risk to pDDIs, particularly to major- and moderate-pDDIs. Screening of prescriptions for pDDIs and monitoring of pharmacotherapy in terms of response and associated adverse drug events will contribute to patient safety.

High prevalence of the risk factors for QT interval prolongation and associated drug-drug interactions in coronary care units.

OBJECTIVES: Patients admitted in coronary care units are susceptible to QT interval prolongation due to numerous risk factors. The purpose of this study was to identify the prevalence of risk factors for QT interval prolongation; QT prolonging medications; drug-drug interactions; their predictors; and torsades de pointes risks of drugs. METHODS: After obtaining approval, this cross-sectional study was carried out during one-year period in coronary care units of two major tertiary care hospitals of Khyber Pakhtunkhwa, Pakistan. The Arizona Center for Education and Research on Therapeutics QT drugs lists and Micromedex DrugReax® were used to identify the QT prolonging medications and QT prolonging drug-drug interactions. RESULTS: Total 649 patients were included in this study. The most frequent QT prolonging risk factors included use of ≥ 1 QT prolonging drugs (74.9%) and myocardial infarction (61.3%). Total 181 patients were presented with 361 QT prolonging drug-drug interactions. There was significant association of the occurrence of QT prolonging drug-drug interactions with female gender (p = 0.01), 9-10 prescribed medications (p = 0.001), and > 10 prescribed medications (p < 0.001). CONCLUSIONS: The majority of patients presented with multiple risk factors for QT prolongation in coronary care units which may precipitate lethal outcomes.

Detoxification of textile effluent by fungal treatment and its performance in agronomic usages.

Globally, scarcity of contaminant free water usages is increasing gradually; it might be solved after generation of any sustainable technology to detoxify contaminated waters. An attempt was undertaken to detoxify textile effluent with fungal strains Trichoderma harzianum and Mucor hiemalis. Fungal detoxified effluent and its performance on three crops (wheat, mungbean, and mustard) seed germination in petri dishes and seedlings establishment of mustard in polythene bag were evaluated. Fungal strains significantly detoxified textile effluent by removal of 76% total solids, 91.35% COD, 77.34% absorbance against optical density, and increased 87.31% DO. Studied heavy metals were reduced significantly (P ≤ 0.05) in treated effluent by both fungal strains but superior performance was achieved by Mucor hiemalis. Maximum 92.5, 88.7, 83, and 100% removal of Mn, Zn, Cu, and Fe were monitored in fungal-treated effluent, respectively. Seeds germination and seedling growth by fungal treated effluents were similar and insignificant with the results achieved in tap water but which was significant over raw textile effluent. Eighty and above percent seed germination in petri dishes was recorded at 48 h by Mucor hiemalis-treated textile effluent but conversely at the same period it was below 10% in raw effluent. Significant achievement of seedling establishment was noticed in poly bag with fungal-treated effluent. The applied technique might be a prospective way to detoxify and recycle the industrial effluents for beneficial purpose in the future.

Drug-Drug Interactions in Hepatitis Patients: Do these Interactions Matter in Clinical Perspectives?

INTRODUCTION AND AIM: Hepatitis patients usually present with comorbidities and polypharmacy which increases risk of potential drug-drug interactions (pDDIs). We explored frequency, levels, predictors, and clinical relevance of pDDIs in hospitalized hepatitis patients. MATERIAL AND METHODS: Retrospective cohort study was used. Clinical profiles of 413 hepatitis patients were reviewed for pDDIs using Micromedex-DrugReax. Frequency, levels and clinical relevance of pDDIs were reported. Logistic regression analysis was used to calculate odds-ratios for predictors. RESULTS: Of total 413 patients, pDDIs were reported in 55.2%. Major-pDDIs were found in 35% patients. Total 660 pDDIs were identified, of which, 304 (46%) were of major-severity and 299 (45%) of moderateseverity. Patient's profiles of top-10 major-pDDIs were presented with signs/symptoms such as fever, hepatomegaly, anorexia, jaundice, hypertension, tachycardia, bradycardia, & pedal edema; and abnormalities in labs such as electrolytes-level, alanine aminotransferase, blood urea nitrogen, bilirubin-level, & serum creatinine. Significant association was observed for the presence of pDDIs with > 9 prescribed medicines (p < 0.001), hospitalization of > 5 days (p = 0.03), and stroke as comorbidity (p = 0.05). Moreover, odds of exposure to major-pDDIs were significantly higher in patients taking > 9 prescribed medicines (p < 0.001), hospitalization of > 5 days (p = 0.002), and stroke as comorbidity (p = 0.002). CONCLUSION: We observed hepatitis patients presented with a considerable number of clinically relevant pDDIs. Attention should be given to widespread major-pDDIs and their potential adverse outcomes. Clinically relevant parameters, such as labs and signs/symptoms should be monitored particularly in high risk patients having polypharmacy, prolong hospitalization, and stroke as comorbidity.

Management Of Diabetes In Ramadan.

Ramadan, the ninth month of Islamic calendar brings alongwith it a sense of responsibility to fast among the Muslim adult population. Though patients with chronic illnesses like Diabetes mellitus are exempted from fasting during the month if their health does not allow, they still wish to fast. This creates a challenge for the health care professionals to enable the patients with Diabetes mellitus to fast safely, without developing complications like hypoglycemia, hyperglycemia, ketoacidosis and thrombosis. This article has reviewed multiple articles published over last two decades to develop a consensus plan regarding management of Diabetes mellitus in Ramadan. Insulin sensitizers are a better option than drugs increasing secretion of insulin. Type 2 Diabetic patients can fast much safely as compare to Type 1 Diabetics.

Prevalence of QT interval prolonging drug-drug interactions (QT-DDIs) in psychiatry wards of tertiary care hospitals in Pakistan: a multicenter cross-sectional study.

Background QT prolongation and associated arrhythmias, torsades de pointes (TdP), are considerable negative outcomes of many antipsychotic and antidepressant agents frequently used by psychiatric patients. Objective To identify the prevalence, levels, and predictors of QT prolonging drug-drug interactions (QT-DDIs), and AZCERT (Arizona Center for Education and Research on Therapeutics) classification of drugs involved in QT-DDIs. Setting Psychiatry wards of three major tertiary care hospitals of Khyber-Pakhtunkhwa, Pakistan. Method This was a multicenter cross-sectional study. Micromedex DrugReax was used for identification of QT-DDIs. TdP risks were identified by the AZCERT classification. Multivariate logistic regression analysis was performed to identify predictors of QT-DDIs. Main outcome measure Prevalence of QT-DDIs (overall, age-wise and gender-wise) and their levels of severity and documentation; AZCERT classes of drugs involved in QT-DDIs; and odds ratios for predictors of QT-DDIs. Results Of 600 patients, 58.5% were female. Median age was 25 years (IQR = 20-35). Overall 51.7% patients had QT-DDIs. Of total 698 identified QT-DDIs, most were of major-severity (98.4%) and fair-documentation (93.7%). According to the AZCERT classification, 36.4% of the interacting drugs were included in list-1 (known risk of TdP), 26.9% in list-2 (possible risk of TdP) and 27.5% in list-3 (conditional risk of TdP). Drugs commonly involved in QT-DDI were olanzapine (n = 146), haloperidol (138), escitalopram (122), risperidone (91), zuclopenthixol (87), quetiapine (n80) and fluoxetine (74). In multivariate logistic regression analysis, QT-DDIs were significantly associated with 6-7 prescribed medications (p = 0.04) and >7 medications (p = 0.03). Similarly, there was significant association of occurrence of QT-DDIs with 2-3 QT drugs (p < 0.001) and >3 QT drugs (p < 0.001). Conclusion A considerable number of patients are exposed to QT-DDIs in psychiatry. There is a need to implement protocol for monitoring the outcomes of QT-DDIs.

QT interval prolongation in hospitalized patients on cardiology wards: a prospective observational study.

PURPOSE: Prolonged QT interval may lead to a lethal form of arrhythmia, torsades de pointes (TdP), which is associated with cardiovascular mortality. Therefore, we aimed to identify prevalence of QT interval prolongation, compare clinical characteristics of patients with normal and prolonged QT interval, and identify predictors of QT interval prolongation. METHODS: A prospective observational study was conducted in cardiology wards of two teaching hospitals in Pakistan. Bazett's correction formula was used for the calculation of QTc interval. Prevalence of QT prolongation and pro-QTc scores were calculated. Comparative analysis was performed with respect to various clinical characteristics by applying t test and chi-square test. Odds ratios were calculated using regression analysis. RESULTS: Among 417 patients, 44.6% were found having prolonged QT interval, of which, 17.3% presented with an abnormally high QTc interval (> 500 ms). Significant difference was recorded between the groups (normal vs. prolonged) with respect to age, all prescribed medications, QT drugs, number of risk factors, QT-DDIs (QT-prolonging drug-drug interactions), gender, and diuretics use. Multivariate logistic regression analysis showed significant results for various predictors such as male gender (p = 0.03), various age categories 41-50 years (p = 0.04), 51-60 years (p = 0.01), and > 60 years (p < 0.001), and diuretics (p = 0.008). CONCLUSION: A substantial number of patients in cardiology wards presented with QT prolongation. Proper considerations are needed in order to minimize the associated risk particularly in patients with abnormally high QT prolongation, old age, polypharmacy, one or more QT-prolonging drugs, and high pro-QTc scores.

Analytic Study In Patients Presenting To A Tertiary Care Hospital Regarding The Artemether-Lumefantrine Induced Qtc Interval Changes In ECG.

BACKGROUND: Malaria is one of the most common causes of morbidity and mortality in our part of the world. Artemether-Lumefantrine (AL) Combination therapy is widely used for the treatment of malaria both in outpatients and inpatients hospital settings. Some of the previous anti-malarial were associated with prolongation of QTc interval. Similar query was raised about AL therapy. This study was conducted to determine the risk of QTc interval prolongation in ECG of patients with Falciparum malaria using oral Artemether-Lumefantrine (AL) combination therapy. METHODS: The venue of this analytical, quasi-experimental study was Medical Unit A, Khyber Teaching Hospital Peshawar, spanning 1st August 2015 to 31st July 2016. The study sample included male and female patients, having Plasmodium falciparum rings in their peripheral smear. These patients were treated with oral Artemether- Lumefantrine (AL) combination for 3 consecutive days in recommended doses. Electrocardiography (ECG) profile before and after 72 hours' treatment with AL was noted for discernable QTc interval changes. The calculated prolongation of the QTc interval between these two study points was analyzed using Paired samples t-test. The statistically significant P value for this study was 0.05. SPSS version 23 was used for statistical analysis. RESULTS: Amongst 200 cases, the QTc interval was noted to be normal before the start of the treatment in all. There was no significant prolongation of QTc interval following the treatment (p-value=0.119) in the treated patients. It appears that cardiotoxicity is a remote adverse effect of AL combination therapy and that its use is safe in patients with Falciparum malaria. CONCLUSIONS: It can thus be concluded that AL is a safe drug combination for the treatment of falciparum malaria with negligible cardiotoxic adverse effects.

Potential drug-drug interactions in pediatric patients admitted to intensive care unit of Khyber Teaching Hospital, Peshawar, Pakistan: A cross-sectional study.

PURPOSE: To investigate frequencies, levels, clinical relevance and predictors of potential drug-drug interactions (pDDIs) in pediatric intensive care unit (PICU). METHODS: Case notes of 411 patients were reviewed for pDDIs through Micromedex. Frequencies, levels and clinical relevance of pDDIs were reported. Logistic regression was applied to calculate the odds-ratios for predictors of pDDIs. RESULTS: We recorded pDDIs in 59.4% patients. Major-pDDIs were found in 34.5% patients. Total 990 pDDIs were identified, of which, 37.8% were of moderate-severity and 30.6% of major-severity. Patient's case notes of top-ten pDDIs showed presence of signs/symptoms such as fever, jaundice, vomiting, anorexia, tachycardia, drowsiness, & lethargy; and abnormalities in labs such as total leukocytes count, blood urea nitrogen, alanine aminotransferase, & potassium-level. Odds of exposure to major-pDDIs were significantly higher in patients aged 6-12years (p=0.008); hospital stay of ≥7days (p=0.05); and ≥11 prescribed medicines (p<0.001). CONCLUSION: Substantial numbers of patients in PICU are exposed to pDDIs. Major-pDDIs are of particular concern. Timely identification of pDDIs, preferably with computerized source, is crucial point for their management. Monitoring of clinically relevant parameters and identification of various predictors are needed to minimize or prevent the associated negative consequences of pDDIs.

Classic Raymond Syndrome.

Classic Raymond syndrome presents with abducens nerve palsy on the ipsilateral side with contralateral hemiparesis and facial nerve paralysis. A 60-year gentleman presented with deviation of left angle of mouth and right sided weakness. Examination showed that he had left sided abducens nerve palsy, with contralateral central facial paralysis and paresis. MRI of brain confirmed left pontine infarct. These findings were consistent with classic Raymond syndrome. Till now, only a few cases have been reported worldwide, this being the first case reported in South Asia. This case confirms that classic Raymond syndrome is different from the common type of Raymond syndrome in terms of sparing of coritcofacial fibers in the latter type.

Mean Platelet Volume (MPV) as an indicator of disease activity and severity in lupus.

Background: Systemic lupus erythematosus (SLE) is a relatively uncommon disease of young females in Pakistan. Usually, it has a relapsing-remitting course with variable severity and disease activity. Amongst the different clinical and laboratory parameters used to monitor disease activity in lupus, mean platelet volume (MPV) is a novel biomarker. Although MPV has been studied in other rheumatological conditions like rheumatoid arthritis, its role in adult SLE needs to be defined, especially in Pakistan.  Methods: The aim of this study was to evaluate the role of MPV as a biomarker of disease activity in SLE. This study included 25 patients with active SLE, and another 25 participants with stable, inactive lupus. MPV was measured in each group and compared using SPSS version 16. MPV was also correlated with SLE disease activity index (SLEDAI) and erythrocyte sedimentation rate (ESR). Independent sample t-test and Pearson's correlation tests were applied. Sensitivity and specificity of MPV were checked through ROC analysis.  Results: The MPV of patients with active SLE (n=25, mean [M]=7.12, SD=1.01) was numerically lower than those in the inactive-SLE group (n=25, M= 10.12, SD=0.97), and this was statistically significant ( P<0.001). MPV had an inverse relationship with both ESR (r=-0.93, P<0.001) and SLEDAI (r= -0.94, P<0.001). However, there was a strong positive correlation between ESR and SLEDAI (r=0.95, P<0.001). For MPV, a cutoff value of less than 8.5fl had a sensitivity of 92% and a specificity of 100% ( P< 0.001).  Conclusions: Higher disease activity in SLE is associated with a correspondingly low MPV.

Psoriatic Arthritis Is an Indicator of Significant Renal Damage in Patients with Psoriasis: An Observational and Epidemiological Study.

Background. Psoriasis affects joints in around 30% of the patients. Recent studies have demonstrated an increased risk of essential hypertension, ischemic heart disease, and stroke in psoriatic patients. However, the prevalence of renal disease in patients with psoriasis has not been evaluated properly. Objectives. Objectives were to evaluate renal functions in patients with psoriasis and to assess any possible relationship of renal failure with psoriasis and psoriatic arthritis. Methods. In this cross-sectional study, 30 participants were recruited into the following three groups: group-A, psoriatic arthritis; group-B, psoriasis without arthritis; and group-C, healthy subjects. Renal function tests were performed for every participant of each group. The data was analyzed by using SPSS version 16. Chi-squared and one-way ANOVA tests were applied, considering a P value of less than 0.05 as a standard criterion. Results. Serum creatinine, urea, and phosphate were the highest in group-A, higher in group-B, and normal in group-C, P < 0.05. Similarly, GFR was the lowest in group-A, lower in group-B, and normal in group-C. The difference in mean GFR values was statistically significant, F(2) = 355, P < 0.001. Moreover, proteinuria (gm/day) was seen in 96.7% of the patients with psoriatic arthritis, (M = 1.18 ± 0.55, P < 0.05) against 10% of the psoriatic patients without arthritis (M = 0.41 ± 0.10, P < 0.05). Conclusion. Derangement of renal function is more prevalent in psoriatic patients, especially in those with concomitant psoriatic arthritis. Therefore, each psoriatic patient must be routinely screened for an underlying renal failure.

Vanishing White Matter (VWM) Disease Presenting As Neuro-Ovarian Failure.

A 19-year girl was admitted with a one-month history of worsening spastic paraparesis, cerbellar ataxia, visual decline and worsening headaches on a background of walking difficulty, progressive quadriparesis and migraine since the age of 10 years. She had no sensory loss, and cranial nerves examination was notable for optic atrophy with crescent formation only. She had primary amenorrhea and underdeveloped secondary sexual characteristics. Ultrasonograhic studies of the pelvis confirmed small ovaries, and uterus. The magnetic resonance imaging (MRI) of the brain showed diffuse leukodystrophy. A diagnosis of leuko-ovarian syndrome or vanishing white matter (VWM) disease was made on the basis of Van der Knaap criteria. To the best of their knowledge, the authors are most probably reporting the first ever case of this rare clinical entity from Pakistan with special focus on its diagnostic and management challenges in the light of limited retrospective case reviews.
