Pituitary Tuberculoma

Tuberculosis rarely involves the hypothalamo-pituitary region and constitutes only 1% of the lesions involving the sellar and/or suprasellar region. Coleman and Meredith first reported pituitary tuberculosis in 1940, and only a handful of cases have been reported ever since. It may manifest as a chiasmal syndrome due to compression of the optic chiasm or as hypopituitarism due to pituitary destruction. It has a characteristic radiological appearance and can mimic a pituitary adenoma. Diagnostic procedures, such as trans-sphenoidal biopsy, are crucial for accurate diagnosis. We report a case of a 32-year male, who presented with complaints of headache and decreased visual acuity for the past 6 months. Eye examination revealed bitemporal hemianopsia. Brain MRI scan showed a mass in the sella with features suggestive of pituitary adenoma. Transcranial resection of the mass was performed; histopathology of the excised mass proved it to be a pituitary tuberculoma

Sprengel\u27s deformity

Various shoulder bone deformities have been identified in the pediatric age group, with the most common being undescended scapula. Sprengel\u27s deformity is dysplasia and malposition of the scapula, especially in the supraspinatus portion, mainly due to abnormal descent in the embryonic period. The clavicle is shorter and has a different contour. In some patients cervical spine deformities are also noted. This is a case of 3 years old girl presented to the clinic with difficulty in abducting right shoulder and sleeping with an internal rotation of the right arm. With physical examinations and radiological investigations sprengel\u27s deformity was diagnosed. Sprengel\u27s deformity is a male predominant disease which almost never occurs in isolation and is usually associated with deformities in the thoracic rib cage and the cervical and thoracic vertebrae. Our patient also had hyperpigmentation along the lines of Blaschko, which has never been previously reported with Sprengel\u27s deformity. Sprengel\u27s may have an association with cutaneous mosacism syndrome

Challenges of training and delivery of pediatric surgical services in developing economies: A perspective from Pakistan

Background: As the pediatric population requiring health services rises globally, developing countries are struggling to cater to the growing burden of non-communicable diseases - particularly those requiring specialized surgical care.Main body: Despite the literature supporting specialized pediatric surgical care, the developing world is far from meeting the American Pediatric Surgical Association (APSA) Manpower taskforce recommendation of at least 1 qualified pediatric surgeon per 100,000 patients (0-15 years-old). In Pakistan, there is an unmet surgical need in the pediatric population due to a multitude of short shortcomings, notably in quality and quantity of the training programs on offer, and urgent short- and long-term steps are needed to improve this dire situation.Conclusion: It is crucial for the global surgical community to take steps, especially with regards to pediatric surgical training, to ensure delivery of accessible and quality surgical care to the world\u27s children

Tobacco control laws in Pakistan and their implementation: A pilot study in Karachi

Objective: In order to limit the high prevalence of tobacco use in Pakistan various tobacco control laws have been implemented. The objective of this study is to serve as a pilot study to assess the implementation of these laws in the largest city of Pakistan, Karachi. Methods: A cross-sectional study was conducted in Karachi. The implementation of tobacco control laws in \u27smoke-free\u27 places, the adherence of tobacco companies to these laws, the regulation of cigarette sale, and the awareness and views of the general public regarding tobacco control laws were assessed via direct observation by visits and through self-administered questionnaires. Results: The implementation of tobacco control laws in \u27smoke-free\u27 public places was found to be poor. Out of 37, only 23(62%) brands displayed pictorial warnings on their packs. 3(8%) of the brands were available in two different kinds of packs, both with and without pictorial warnings. Cigarette sale to minors was taking place at 80(85%) of the visited cigarette outlets. 50(53%) of the outlets displayed cigarette advertisements in the form of posters. 46(40%) of the persons questioned had awareness regarding the existence of ban on smoking in public places and 126(90%) of these were in favour of it. CONCLUSIONS: The implementation of tobacco control law in Pakistan is poor. Non adherence to the law in public places was alarmingly high. Also, the study demonstrates the poor compliance to the tobacco control laws by tobacco companies. The sale of cigarettes is almost unregulated

Enteric cyst in the left posterior mediastinum mimicking a hydatid cyst on chest computed tomography scan

Abstract Mediastinal enteric cysts are a rare occurrence among adults and are usually asymptomatic. In most cases they are an incidental finding in the right hemi-mediastinum and are associated with vertebral anomalies. We report the unusual case of a 23 year old male who had a mediastinal mass on chest X-ray as an incidental finding. Chest Computed Tomography (CT) scan revealed no vertebral anomalies and a cystic mass in the left posterior mediastinum with features similar to those of a hydatid cyst.Posterolateral thoracotomy was done and the cyst was excised. Histopathology report revealed it to be an enteric cyst

Mabry syndrome in a child of South Asian descent

Mabry syndrome is the triad of seizures, hyperphosphatasia, and mental disability. It usually manifests in first year of life and has an autosomal recessive mode of inheritance. Besides the usual triad, other manifestations of Mabry syndrome include hypoplasia of distal phalanges, brachytelencepahly, gastrointestinal malformations and constipation, hypertelorism, short nose with a broad nasal bridge and dip, and thin upper lip with down turned corners of the mouth. More than 20 cases of Mabry syndrome have been reported in medical literature. Herein, we report the case of a six-month child with Mabry syndrome that presented with decreased neck holding, hypotonia and delayed motor milestones. The child also had a high-arched palate and hyperplastic malar eminences. Constipation was present but had a delayed onset, starting at 19 months of age. This is the first case of Mabry syndrome occurring in a child of South Asian descent

Neurofibromatosis type 2 patient presenting with medulloblastoma

Background: Neurofibromatosis type 2 (NF2) is an autosomal dominant syndrome with a frequency of 1 in 25,000 live births and a penetrance of almost 100% by the sixth decade of life. The main tumors occurring in NF2 patients are bilateral vestibular schwannomas, other peripheral, cranial and spinal nerve schwannomas, intracranial and intraspinal meningiomas, ependymomas, and gliomas.Case description: We report the case of a 6-year-old boy who presented with a 1-month history of nausea and recurrent vomiting. Physical examination was positive for ataxic gait and left-sided facial nerve palsy. Family history was positive for NF2 in the patient\u27s father and paternal uncle. Magnetic resonance imaging brain revealed a solid enhancing lesion arising from the right cerebellar cortex, which was effacing the fourth ventricles and causing hydrocephalus. Craniotomy and excision of the lesion were performed. Histopathology report confirmed the diagnosis to be desmoplastic medulloblastoma. Based on the patients\u27 subsequent history and family history, he was diagnosed to be a case of NF2.Conclusion: This is the first case of medulloblastoma occurring in a patient with NF2 and raises the possibility of an association between medulloblastoma and NF2

Hepatocellular carcinoma with extrahepatic blood supply from right renal artery

Extrahepatic blood supply is seen in around 17-27% of hepatocellular carcinoma lesions. Evidence suggests that this extrahepatic supply most commonly originates from a right intercostal artery (70-83%) followed by left intercostal, omental and right renal arteries. Thus a comprehensive knowledge of variations in standard vascular anatomy and cognisance of factors influencing or predicting extrahepatic blood supply in HCC is instrumental in ensuring the success of surgical and interventional procedures. We present the unusual case of a 66-year-old male with HCC in Segment I of the liver with aberrant blood supply from the right renal artery in the absence of any risk factors for extrahepatic circulation. He successfully underwent transarterial chemoembolization. There was no evidence of residual disease on repeat imaging

Sex and the streets: The open secret of sexual abuse among Pakistan\u27s two million street children

Background: About two million children live on the streets in Pakistan. Their complicated past and dire living conditions make them susceptible to many psychological and physical problems, including sexual abuse.Main body: With little research on the topic, the prevalence of sexual intercourse among street children is reported to be as high as 88% in Pakistan. With commercial sex a common practice among the street children, public places such as bus terminals and parks have become foci of prostitution and sexual exploitation. A growing concern is the spread of HIV/AIDS among the affected children due to a general lack of awareness about the disease and its prevention and high prevalence of unsafe sexual practices. The generally apathetic attitude of the society towards this issue and the affected children, combined with a lack of commitment and limited resource allocation by the government, has contributed in deteriorating the situation further.Conclusions: A comprehensive multi-pronged strategy involving government, societal and international stakeholders is crucial to tackle the current crisis
