Aims: To evaluate the possible in vitro interaction between methanolic extract of root of Adiantumcapillus-veneris and
certain known antimicrobial drugs i.e. Oxacillin, Ceftazimide, Cefriaxone, Ofloxacin, Meropenem, Erythromycin,
Cefuroxime, Cefoxitin, Cefotaxime and Ampicillin.
Methodology and results: The study was carried out against ten bacterial strains (Staphylococcus aureus, S.
epidermidis, Salmonella typhi, Klebsiella pneumoniea, Shigella dysentriea, Proteus vulgaris, Pseudomonas aeruginosa,
Providencia species, Citrobacter freundii and Escherichia coli isolated from urine, pus and blood samples. Both disc
diffusion and well diffusion methods were used to determine antimicrobial activity of plant extract in combination with
antibiotics. Antimicrobial sensitivity showed that Meropenem was the most effective antibiotic with zone of inhibition (ZI)
of 25-33 mm among all tested antibiotics followed by Ofloxacin (10-26.5 mm), Ceftriaxone (8-20 mm), while Oxacillin
showed no activity against almost all bacterial strains. The study showed that most bacterial strains were resistant to
most of the antibiotics used, ranging from 20-60%. The methanolic extract (mEXT) of A. capillus-veneris used alone was
active against most of the bacterial isolates with maximum activity against E. coli with 16 mm ZI. The study also
indicated that there was an increased activity in case of combination of mEXT with antibiotics. The combined effects of
plant extract with antibiotics were synergistic against most of the bacterial strains. The mEXT showed maximum
synergistic effect with Ceftazimide with ZI of 42 mm followed by Meropenem (40 mm) and Ceftriaxone (28 mm) against
multidrug-resistant (MDR) bacterial strains.
Conclusion, significance and impact of study: The data suggests that plant extract could be used as alternative to
antibiotics. These results give scientific backing that combination between plant extract and antibiotics would be useful in
fighting the emerging drug-resistant bacterial pathogens.

Schwannomas, or neurinomas, are generally benign, slow-growing, asymptomatic neoplasms
originating from the Schwann cells of a nerve sheath. As a part of spindle cell mesenchymal tumours,
schwannomas arising from the gastrointestinal tract (GIT) are unusual; however, when they occur,
the most common site involved is the stomach, which represents 0.2% of all gastric tumours. We report
the case of a 35-year-old female patient with a history of pulmonary tuberculosis presenting with a
large palpable abdominal mass reaching up to the peritoneal cavity. The initial clinical impression
was a tuberculous abdominal mass, a cyst, or a teratoma. However, intra-operative findings during a
subtotal gastrectomy revealed an exophytic gastric serosal mass, which suggested a gastrointestinal
stromal tumour (GIST). Post-operative histopathological findings showed a fascicular arrangement
of neoplastic spindle cells with pallisading nuclei that showed intense positivity for S-100 protein,
and were negative for CD117 and desmin in immunohistochemistry studies. These results confirmed
the final diagnosis of a gastric schwannoma.

The jejunum is the longest part of the small intestine and its lumen is mainly involved in the absorption of the nutrients. The present study was conducted to evaluate the effects of metronidazole, ceftriaxoine sodium and their combination on the stenotic index of the end to end jujunal anastomotic site. To accomplish this, 20 healthy stray dogs were subjected to end to end jejunal ansastmosis. Dogs in Group A (control) underwent jejunal anstomosis with no antibiotic prophylaxis, while those in Group B received surgery and metronidazole alone at 50 mg/kg, those in Group C received ceftriaxone sodium intravenously at 30 mg/kg body weight prior to surgery and dogs in Group D were given metronidazole in combination with ceftriaxone sodium at 50 mg/kg and 30 mg/kg, respectively, 2 h before surgical intervention. No significant difference (p > 0.05) in the stenotic index was observed at 14 days after jejunal anastomosis. These findings indicate that prophylactic administration of metronidazole and ceftriaxone sodium alone or in combination had no significant effect on the stenotic index of the jejunum.

Congenital insensitivity to pain with anhidrosis is a rare autosomal recessive disorder presenting
with loss of pain sensation, thermal sensation defects, and self-mutilating behavior. In the present
study, we recruited two consanguineous pedigree showing pain insensitivity symptoms from Pakistan
for clinical and molecular investigations. In family A, one female patient displayed classical CIPA
symptoms along with microcephaly and severe intellectual disability. During course of the disease,
her right foot was amputated and had remarkable dental degeneration and teeth shedding. In family B,
one boy presented with classical symptoms of congenital insensitivity to pain with anhidrosis. Blood
was collected from both families for molecular studies. Sequencing with the Ilumina Trusight One
Sequencing Panel covering 4813 OMIM genes revealed a known homozygous mutation c.2084C>T;
p.P695L of NTRK1 in family A and a novel truncated mutation c.2025C>G; p.Y681X in family B.
Protein modeling analysis of both mutations (p.P695L and p.Y681X) predicted loss of the rigidity in
tyrosine kinase domain of NTRK1 that led to conformational changes as well as deleterious effect on
protein function. The known mutation was reported more than a decade ago in a family from Northern
Israel and other non-sense mutation is newly identified. It is interested that most of NTRK1 mutations
are associated with this domain. This is first ever report of NTRK1 variants in congenital insensitivity
to pain with anhidrosis patients from Pakistan.

For the development of 19-plex Y STR system and polymorphism studies in locl ethnic populations sixteen markers of non-recombining regions (NRY) of Y chromosome, which show high power of discrimination among individuals, were selected in this study. Blood samples (600) were e.ollected from the males of three most common castes of Pakistani population (Arnin, Awan and Rajput) with different parent lineages. Three markers (DYS385a/b, DYS389Ⅰ/Ⅱ and YCAⅡa/b) among 16 Y STRs are double-targeted regions of the Y chromosome and thus provide two polymorphie peaks for each respective primer set. These 16 Y-STRs were developed into Megaplex system for simultaneous amplification of all markers within the population. The overall power of discrimination observed in focused populations was 60.5%, 66.5% and 55% in Rajput, Awan and Arain casts respectively. This discrimination power will be helpful in haman identification for forensic casework studies including sexual assaults and paternity testing.

Epilepsy surgery is a well-established treatment for drug-resistant epilepsy, with awake craniotomy being used in certain cases to remove epileptogenic foci while preserving crucial brain functions. We are presenting the first reported case from Pakistan of a 19-year-old woman who underwent awake epilepsy surgery to treat cortical dysplasia. She had a history of generalized tonic-clonic seizures since her childhood and was referred to our clinic due to an increase in seizure frequency. EEG and MRI identified the epileptogenic focus in the right parieto-temporal region. The patient underwent a neuro-navigation guided awake craniotomy and an excision of the epileptogenic focus in the right parieto-temporal region. The procedure was carried out using a scalp block and dexmedetomidine for conscious sedation, enabling the patient to remain awake throughout the surgery. Intraoperative mapping and electrocorticography were used for complex multidisciplinary care. Post-resection corticography showed no spikes along the resected margins. The patient was discharged without any complications and remained free of symptoms a year after the surgery. Awake epilepsy surgery is a viable option for removing epileptogenic foci while preserving vital cognitive functions. However, it is seldom used in low- and middle-income countries such as Pakistan. The successful outcome of this case underscores the need for greater awareness and availability of epilepsy surgery in resource-limited settings. Cost-effective measures, such as using small subdural strips for intraoperative localization, can be implemented.

Objective To determine the asymptomatic dengue infection in adults of Pakistani population. Methods This study was conducted in five major cities (Islamabad, Karachi, Lahore, Multan, and Peshawar) of Pakistan. A total of 5 230 adults aged 18 years and above without a history of dengue fever at any point in their life were enrolled from participating laboratories. Those who were confirmed for dengue previously were excluded. Of the total, 62.6% (n = 3 276) were male with an average age of 34.6 years. Participants were briefed about the objectives of the study, and written consent was obtained to perform dengue IgG test using enzyme linked immunosorbent assay. The brief information related to age, gender and area was also taken on proforma. Results Overall 32.3% (n = 1 691) was having asymptomatic dengue infection which was 67.5% (n = 756) in Karachi followed by 39.1% (n = 391) in Islamabad, 29.9% (n = 316) in Lahore and 21% (n = 228) in Peshawar and none from Multan. More males were affected with asymptomatic dengue infection than females. The asymptomatic dengue infection was significantly higher in different cities; however, there was no significant difference with respect to age groups. Conclusions The asymptomatic dengue infection is higher in cities i.e. Karachi, Islamabad and Lahore which are at risk of developing secondary dengue infections. There is a need of awareness among the public about secondary dengue infection.
