ABSTRACT
Rationale: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been recognized as highly pathogenic. The current pandemic of SARS-CoV-2 has been spread globally and infected more than 200 countries. Patient concerns: We report the first confirmed fatal case of COVID-19 in Pakistan. A 50-year-old man returned from Saudi Arabia on March 09, 2020 and presented with cough, fever, malaise, poor appetite and difficulty in breathing to the Pulmonologist at District Headquarter Hospital Mardan. Diagnosis: The patient was initially diagnosed as COVID-19 suspected case. A oropharyngeal swab sample was positive by realtime RT-PCR tests. Lessons: This report highlights the importance of close coordination between clinicians and public health authorities as well as the importance of early laboratory-based confirmation of COVID-19 cases.
ABSTRACT
From 2013 to 2015, the National Institute of Health, Pakistan, received 1,270 blood samples of suspected dengue cases reported from inpatient and outpatient departments of various hospitals in Khyber Pakhtunkhwa (KPK) province. In this study, we determined the circulating dengue virus (DENV) serotypes using real-time reverse transcriptase (RT)-PCR to understand the serotype-based epidemiology of DENV. All four serotypes (DENV-1 [6%], DENV-2 [33%], DENV-3 [47%], and DENV-4 [0.1%]) were found circulating during the study period. Our findings suggest the need for an active surveillance system coupled with the laboratory diagnosis, especially in the chronic endemic areas of the country. Public awareness programs are needed for effective control and prevention of outbreaks in the future.

ABSTRACT
To determine the clinical and demographic characteristics of children diagnosed with Subacute sclerosing panencephalitis [SSPE]. Case series. The Aga Khan University Hospital, Karachi, from January 2000 to June 2012. A retrospective analysis was done, regarding medical charts of 43 children under the age of 16 years with a discharge diagnosis of SSPE. Demographic and clinical characteristics were recorded. Results were expressed as percentages. Most of the 43 patients were male [72%]. The average age at presentation was 8.7 years with average duration of symptoms being 100.6 days. History of measles was present in 17 patients [39.5%]. All children had seizures at presentation and 65% had cognitive impairment. Most patients required poly therapy for control of seizures. Sodium valproate was the most commonly used anti-epileptic agent; Isoprinosine was tried in 22 [51%] patients. CSF for antimeasles antibodies was positive in approximately 86% of the 40 [93%] children. EEG showed burst suppression pattern in 36 [83.7%] cases. Forty-two patients [97.6%] were discharged home in a vegetative state. SSPE is progressive neurodegenerative disorder. It can be prevented by timely immunization against measles. Measles antibody in the CSF is diagnostic for SSPE and is helpful in early diagnosis. Most patients experience a gradual but progressive decline in motor and cognitive functions
ABSTRACT
To determine the frequency of clinical features of Celiac disease [CD] and Celiac crisis in children. Case series. Paediatrics Unit, Sheikh Zayed Medical College and Hospital, Rahim Yar Khan, from September 2009 to September 2010. Forty children aged between 4 to 13 years of either gender, presenting with complaints of recurrent diarrhea, abdominal distention, severe emaciation and dehydration were included. The information about breast feeding, weaning diets, age of introduction of wheat diets, onset of diarrhea, characteristics and frequency of stools, growth, vaccination status, symptoms in 1st degree relatives, restriction of Gluten diet in the past and anthropometric measures were recorded. Serological tests against anti-Tissue Transglultaminase [anti-tTG] antibodies were obtained in all cases. Upper gastrointestinal endoscopies were performed and multiple biopsies were taken from distal parts of duodenum. Among the forty children, twenty four [60%] were females and 16 were males [40%]. The mean age was 6.35 +/- 2.83 years. Thirty five [87.5%] parents were cousins. Breast feeding was not exclusively given and the Gluten containing weaning diets were given as early as 3.5 months of age. Thirty [75%] children presented with typical sign and symptoms of CD. Celiac crisis presented with profuse diarrhea, severe dehydration; abdominal distention; pedal edema, carpopedal spasm due to tetany; wasted muscles; head drop and inability to stand. The serum TtG antibodies in thirty-eight cases [95%] were above the cut off level of 7u/ml ranging from 35-99 u/ml. The histopathology of specimens from distal duodenum revealed lesions of M3 type in thirteen [32.5%] and M2 type in eighteen cases [45%]. All cases recovered and improved on follow-up after strict adherence to gluten-free diet [GFD]. Majority of children with Celiac disease presented with typical symptom, while Celiac crisis was characterized by severe dehydration, weakness and calcium deficiency signs. Most were the product of consanguineous marriages and were given Gluten - containing weaning foods as early as the 4th month of life

Background: Pregnant women constitute a high risk group for iron deficiency. Maternal iron deficiency and particularly iron deficiency anaemia may be associated with detrimental effects on maternal and infant function and particularly with a higher risk of preterm delivery and delivery of low birth weight neonates. Objective of this study was to assess and compare the iron status of normal healthy non-pregnant women with that of pregnant women of Hazara Division. Methods: This study was conducted at Faculty of Health Sciences, Hazara University, and Ayub Medical College, Abbottabad from 1st March to 31st August 2006. Altogether 120 women, 90 pregnant at various stages of pregnancy and 30 non-pregnant women as control group were included in this study by convenience sampling. Their iron status was assessed by determination of haemoglobin [Hb], Serum ferritin, Serum-iron, Total Iron Binding Capacity [TIBC], Unsaturated Iron Binding Capacity [UIBC], and Percentage saturation of transferrin. Data generated on these variables were subjected to ANOVA and correlation analysis. Results: The salient finding of this study is a significant decrease in Hb, Serum ferritin, Serum iron, percentage saturation of transferrin and a significant increase in values of TIBC and a pronounced increase in UIBC in 2nd and 3rd trimester compared to 1st trimester in iron deficient pregnant women. The mean values of Hb, SF, and Fe/TIBC% were significantly lower in the cases than in the control and significantly higher values of TIBC and UIBC were observed in the cases compared to controls. Significant correlations were observed for TIBC, UIBC and Fe/TIBC% against serum iron in different trimesters of pregnancy. Conclusion: A high percentage of the pregnant women are iron deficient due to factors such as high parity, poor dietary habits and socioeconomic status
ABSTRACT
Hepatitis B is inflammation of the liver caused by a Hepatitis B virus, having a parenteral mode of entry and infecting millions of people around the world. The present study was planned to assess the seroprevalence of Hepatitis B in women of reproductive age in Hazara in order to promote disease prevention in the perinatal period by vaccination against Hepatitis B. Women 15-45 years old belonging to Hazara Division were included in this descriptive, cross-sectional study conducted over a period of one year at the Department of Microbiology, Ayub Medical College, Abbottabad in collaboration with the Department of Pathology, Ayub Teaching Hospital, Abbottabad from 1[st] March 2006 to 28[th] February 2007. Non-probability convenience sampling was done to select 500 females from those visiting Ayub Teaching Hospital Abbottabad as outdoor patients or accompanying person. History, examination, and serum alanine aminotransferase estimation were followed by the initial screening for Hepatitis B surface Antigen [HBsAg] using immunochromatographic device. Enzyme linked Immunosorbent assay was used to confirm the presence of HBsAg. HBsAg was detected in 3% of the women. History of multiple injections was present in 100%, blood transfusion in 22%, dental procedure in 46% and surgical procedure in 43% of the subjects. Only 1% women had been vaccinated. Seroprevalence of the Hepatitis B is not different from the figures reported by the studies previously conducted on general population in Pakistan. However it is different from those reported for the special groups
ABSTRACT
Hepatitis C Virus [HCV], the causative agent of Hepatitis C is prevalent in different countries including Pakistan. Studies have been conducted on various aspects of HCV in Pakistan. The present study was planed to see the prevalence of hepatitis C in pregnant females of Hazara Division. Five hundred pregnant females of reproductive age group from Hazara Division selected by non probability convenient sampling technique were studied from 1st March 2006 to 28th February 2007 at Ayub Teaching Hospital, and District Headquarter Hospitals Abbottabad, Haripur and Mansehra. After initial serving by immunology technique positive cases were confirmed by Enzyme Linked Immunosorbant Essay [ELISA]. Seroprevalence of HCV in pregnant females of Hazara division was 8.9%. Females aged from 25-35 constituted the largest group among positive cases. HCV was more prevalent in District Abbottabad as compared to the other districts of Hazara division. Seroprevalence of HCV in pregnant females of Hazara Division is different from the figures already reported form the other parts of Pakistan
