Penetrating cardiac trauma: A retrospective case series from Karachi

Penetrating cardiac trauma is a medical emergency that commonly affects young men throughout the world. A retrospective review of the records of all patients presenting with cardiac injury was done from January 2000 to December 2015 at our institute. There were 10 cases of such trauma, all of whom were males, 17 to 48 years of age. The most common mechanism of injury was gunshot wounds followed by stab wounds. The Mean Revised Trauma Score was 7.23±0.855. Only 2 out of the total 10 patients died (20% mortality). The Right Ventricle followed by the Left Ventricle was the most common site of injury. Median Sternotomy was the surgical procedure of choice in managing these patients. Pericardial tamponade and Haemothorax were common intra-operative findings. Patients having penetrating cardiac injury presenting with detectable signs of life on arrival to the hospital can be rescued by early surgical intervention.

Awareness, use and perceptions about E-cigarettes among adult smokers in Karachi, Pakistan

OBJECTIVE

To estimate the prevalence of awareness, current use and intention to use of e-cigarettes among adult smokers.

METHODS

This cross-sectional survey was carried out at the Aga Khan University Hospital, Karachi, from July to August 2016, and comprised people aged above 18 years who had smoked more than 100 cigarettes in their lifetime. Convenience sampling method was used. A self-administered questionnaire was used to collect data. SPSS 22 was used for data analysis..

RESULTS

Of the 387 participants, 359(92.8%) were male. The overall mean age was 32.4±12.6 years. Moreover, 215(55.5%) respondents belonged to the middle socio-economic class. Besides, 249(64.3%) respondents were aware of e-cigarettes while 39(10.1%) used them, and 81(20.9%) wanted to use them. Socio-economic status was the best predictor for awareness about e-cigarettes (p<0.001), while gender (p=0.001), occupation<lt;0.001) and current smoking status (p=0.009) were significantly associated with the use of e-cigarettes. E-cigarettes were perceived as less harmful than tobacco cigarettes by 175(45.3%) respondents, helpful in quitting smoking by 138(35.6%), associated with chronic diseases by 158(40.9%), addictive 142(36.7%), and not safe during pregnancy by 197(50.8%) participants.

CONCLUSIONS

The percentage of e-cigarette usage was low despite the higher than expected awareness among the subjects.

Management Of Penetrating Injury To Thoracic Inlet And Lower Neck With Retained Foreign Body Using Video Assisted Thoracoscopic Surgery

Penetrating neck and chest injuries are a common form of occupational injuries. We hereby report a unique case in which a metallic rod had penetrated the left chest and neck of a plastic factory worker. The patient was vitally stable when he presented to Emergency Room. Chest X-ray was performed and the patient was rushed to the operating room. VATS (video assisted thoracoscopic surgery) and neck dissection was done for retrieval of the metallic rod. On table, endoscopy was also done to rule out injury to oesophagus. No injury to vital structures was found and the subsequent recovery was uneventful.

Giant Ganglioneuroma in a 5-Year Child

We report a 5-year boy presenting with pain in the lower chest and upper abdomen. On evaluation with computed tomography scan of the chest, he was found to have a large 16 x 14 cm posterior mediastinal mass compressing the inferior vena cava and liver, and shifting the heart to the opposite side. Tumor was approached via right postero-lateral thoracotomy and dissected off from esophagus, heart, inferior vena cava and lungs. The entire tumor was resected without any complications. Postoperative course was unremarkable. Resection of the tumor was successful. The histopathology showed it to be giant ganglioneuroma with no evidence of malignancy.

Quality of Life in Individuals Surgically Treated for Congenital Hydrocephalus During Infancy: A Single-Institution Experience

BACKGROUND

Congenital hydrocephalus (CH) is a frequently encountered birth anomaly that can hinder long-term neurologic maturity and social well-being of affected children. This study was undertaken to assess quality of life (QOL) 10-15 years after surgical treatment for primary CH during infancy at a tertiary care hospital in a developing country.

METHODS

This retrospective cohort study included individuals who presented to Aga Khan University Hospital, Karachi, Pakistan, between 1995 and 2005 at <1 year old and underwent surgery for primary CH. The Hydrocephalus Outcome Questionnaire was used to assess outcomes with respect to QOL.

RESULTS

Of 118 patients, 90 patients participated in the study. Mean age at first admission was 6.2 months. Mean length of follow-up was 5.4 years. Of these, 28 patients had died after surgery. Shunt infection (P = 0.012) and delayed milestones (P = 0.003) were found to be statistically significant factors affecting mortality in the patients who died. The mean overall health score was 0.67 ± 0.30. Age <6 months at the time of first surgery was a poor predictor of overall health on the Hydrocephalus Outcome Questionnaire (P = 0.039).

CONCLUSIONS

In our analysis, we assessed the QOL associated with CH. We hope that these results will provide insight for future prospective work with the ultimate goal of improving long-term QOL in children with CH.

Distribution of gastric carcinoma in an area with a high prevalence of Helicobacter pylori

BACKGROUND/AIMS

South Asia is an enigma for gastric cancer (GC) because it is a low risk region with a high prevalence of Helicobacter pylori (H. pylori) infections. We evaluated the trend of GC clinical presentation and risk factors in patients with dyspeptic symptoms.

MATERIALS AND METHODS

The medical records of patients, coded by the international classification of diseases (ICD-10-CM, 2015, Diagnosis Code C16.9) for malignancies of stomach diagnosed by esophagogastroduodenoscopy (EGD) and histopathology, were studied.

RESULTS

394 GC cases with a mean age of 54±15 years, range of 18 to 88, were analyzed. 256 (65%) were male. Distal non-cardiac and cardiac tumors were 302 (77%) and 92 (23%) cases, respectively. The WHO classification of GC defined 222 (56%) cases as intestinal type adenocarcinoma, 68 (17%) cases as signet ring cell carcinoma (SRC), 62 (16%) cases as diffuse type and 42 (11%) cases as B cell non-Hodgkin lymphoma. The co-morbid conditions associated with GC were H. pylori infection (positive in 246 (62%) cases), diabetes mellitus type 2 (in 90 (23%) cases), and cigarette smoking (in 94 (24%) cases). Of the male patients, 88 (34%) (p<0.001) were smokers. Body mass index was abnormal in all age groups and in both sexes. Cardiac regions for GC were more common in the 46- to 60-year old age range and in males. Diffuse GC was seen in all age groups but there were significantly more common in the 18- to 45-year old age range. Gastric non-Hodgkin's lymphoma was seen at an early age of 18-45 years in 14(12%) and a later of 61-88 years in 20 (15%).

CONCLUSION

Intestinal type GC is common at all ages but SRC and diffuse GC are more common in patients less than 50 years old. SRC and diffuse GC were not specific to the elderly in our study population.

Retrograde bullet migration from inferior vena cava into right common iliac vein following gunshot: A case report

Bullet embolization cases are rare and even rarer are its retrograde migration in the veins. We report the case of a 14 year old male with a gunshot wound to the left side of his chest. CT scan revealed bilateral haemothorax and foreign body in the right common iliac vein. The patient was immediately taken to the operating theatre and median sternotomy performed. Bullet entry tear was found in the inferior vena cava however, the bullet was found lodged in the right common iliac vein and slipped down against the flow of blood. The bullet was left in situ and after the necessary repair the chest was closed and the patient shifted to the CICU and discharged after 4 days in stable condition. Patient was followed after 1 week and reassured and advised for one year follow-up.

Successful Treatment of Giant Left Subclavian Artery Pseudoaneurysm Abutting the Arch of the Aorta and Descending Aorta

A 28-year-old woman presented with 3-month history of fever of unknown origin and progressively increasing cough. She was diagnosed with pulmonary tuberculosis on bronchial lavage cultures. A chest X-ray performed on follow-up showed a new opacity in the left apical area of the chest. Computed tomography scan of chest showed a large 10 cm pseudoaneurysm of the left subclavian artery 1 cm from its take off from the arch of the aorta. The pseudoaneurysm was approached through a left posterolateral thoracotomy and opened following a proximal and distal control. A 3 cm longitudinal defect was identified in the subclavian artery within its intrathoracic portion. This was debrided and repaired with an autologous pericardial patch. The patient had an uneventful recovery and remained well on follow-up.

Myxoid Liposarcoma Originating In The Anterior Mediastinum

Myxoid liposarcomas of the head and neck are mostly metastatic in nature, with the primary lesion usually in lower extremities or retroperitoneum. Primary mediastinal liposarcomas are even rarer. Although there have been previous cases reporting their incidence, there is no evidence of any case comprising of both the neck and the mediastinal region yet. We here present a case of a 43 year old male with a primary liposarcoma of the myxoid subtype originating in the anterior mediastinum. This is the first time such a case has presented in literature. The patient presented with a right sided neck swelling associated with pain and shortness of breath upon lying down. CT neck revealed an enhancing mass extending from right cervical region to axilla and encasing the subclavian artery and involving a portion of the right lung. The patient underwent wide local excision of the mass along with chemoradiotherapy to prevent recurrence.
