Severe Chest Injury Revisited - An Analysis of The Jos University Teaching Hospital Trauma Registry

Background

Chest injury remains a major source of morbidity and mortality in trauma as approximately two-thirds of all severe traumas involve the chest.

Objective

To determine the changes in the profile management and outcome of severe chest injury in Jos University Teaching Hospital, Jos, Nigeria.

Materials and Methods

This is an analysis of the Trauma Registry of Jos University Teaching Hospital-a prospectively gathered database. Patients' entries with severe chest injuries for 7 years, from January 2012 to December 2018, were entered into a database and analyzed using the Epi Info Statistical Software, using simple statistics.

Results

In all, 162 patients presented with severe chest injury over a 7-year period, of whom 78 (48.1%) had polytrauma, while 84 (51.9%) had isolated chest injury. There were 139 males and 23 females, giving male: female ratio of 6:1. Over 95 (58.6%) of them were between 20 and 39 years. Blunt injury was predominant, constituting 66.7%. Motor vehicular crash was the most common mechanism of injury constituting 87 (53.7%), while gunshot injuries were responsible for 34 (21%). In managing these severe chest injuries, 146 (90%) of the patients had closed-chest tube thoracostomy as the definitive treatment, while 16 (9.9%) had thoracotomy. The mean and median duration of hospital stay was 13.3 and 10 days, respectively. The commonest complication was wound infection in 8 (4.9%) patients and a mortality of 5.9%.

Conclusion

Blunt chest injury remains the commonest mechanism of chest injury but with an increasing proportion of penetrating injuries affecting predominantly young males. Most severe chest injury patients survive with simple interventions of resuscitation, and closed-chest tube thoracostomy for definitive treatment.

COMPLETE OESOPHAGEAL STRICTURE FOLLOWING THYROIDECTOMY FOR BENIGN GOITRE: A CASE REPORT

Oesophageal injury leading to stricture is a dreaded disease with clinical course and prognosis that are dependent on the etiology, early recognition, and prompt and effective treatment. Commonly, iatrogenic oesophageal injury occurs during endoscopic procedures, and often in a diseased oesophagus. Though uncommon, injury can occur during thyroidectomy. We therefore present the case of a Nigerian woman with complete oesophageal stricture resulting from oesophageal injury sustained during thyroidectomy.

CERVICAL LIPOSARCOMA IN A 22 YEAR OLD MAN- AN UNCOMMON PRESENTATION

Liposarcomas are uncommon malignant growths, most of which occur in the retroperitoneum and lower extremities. Liposarcoma arising in the head and neck is an uncommon and a potentially life threatening malignancy. We present a 22 year-old male with a dedifferentiated cervical liposarcoma, who had local excision, with no recurrence at twenty months of follow-up. This patient has drawn our attention to the fact that although liposarcomas are rare in the neck and commonly occur in patients between 40 and 60 years, any neck swelling in the young with atypical features should raise suspicion as to the possibility of malignancy.

TRAUMATIC DIAPHRAGMATIC HERNIA WITH INTESTINAL OBSTRUCTION IN A CHILD: A CASE REPORT

Diaphragmatic ruptures caused by blunt or penetrating trauma are relatively uncommon in children, however, they are the most commonly missed or delayed injuries in trauma patients because of its rarity and its coexistence with more obvious and serious injuries. We present a case of acute intestinal obstruction in a 6-year old boy with traumatic diaphragmatic hernia presented four years after trauma, underscoring the fact that clinical scenario in paediatric patients may not always correlate with the degree of severity of the injury and that some of the classical features of intestinal obstruction could be absent.

HUMAN BITE INJURIES ON THE JOS PLATEAU

BACKGROUND

Human bite injuries with the associated morbidity are not uncommon in this environment.

OBJECTIVE

To determine the pattern, management modalities and treatment outcome of human bites in Jos, Plateau State, Nigeria.

DESIGN

A prospective study of all human bite injuries managed at the Jos University Teaching Hospital, Jos, Nigeria between January 2012 and December 2014.

SETTING

Jos University Teaching Hospital, Jos, Nigeria.

MAIN OUTCOME MEASURES

The pattern and management outcome.

RESULTS

A total of 63 patients with human bite injuries were studied during the three-year period. There were 43 males and 20 females with a male:female ratio of 2:1. The age ranged from 8 - 65 years with a mean age of 30.2+/-17 years; in all about 75% of the patients fell into the 20 - 40 years bracket. Though all the social strata were affected, the bites were more common (50%) among the lower social classes and 70% of the patients presented late after 24 hours of sustaining bite injuries. Pain, bleeding, infected wounds, bite and scratch marks were the main presenting features. About 70% of the patients sustained major bites involving the underlying muscles and deeper structures while 89% of the patients sustained their bites during a fight, 8% while raping their victims, and in 3% of patients as they were being mugged. The bites were between spouses in 39% of cases, and between women in polygamous settings in 16%. The sites commonly affected were the upper limbs in 46%, chest in 21%, ears in 13%, abdomen in 10% and the penis in 6%. The associated injuries were scratch marks in 89%, blunt abdominal injuries in 29%, skin lacerations in 16% and urinary bladder/urethral injuries in 3%. There was no mortality but morbidity was 57% which included infections in 29%, disfigurement in 29%, penile injuries in 6% and minor urethral injuries in 3% of cases.

CONCLUSION

Human bite injuries in this tropical environment commonly affected the young male, the lower social class and the upper limbs; they were commonly sustained in assaults and domestic conflicts.

IMPALEMENT HEAD INJURY WITH A SPEAR

Impalement injuries to the craniofacial region are uncommon due to the fact that the face is a smaller target in relation to the rest of the body. We report a case of a 26-year old man who was attacked on the face with a spear. He was promptly evaluated and resuscitated; the blade of the spear was successfully extracted under general anaesthesia. He was discharged home after 2 weeks hospitalization; he has been followed up for three months with good outcome.

FACTORS DETERMINING THE RESULTS OF THE EXAMINATION OF THE WEST AFRICAN COLLEGE OF SURGEONS IN GENERAL SURGERY

BACKGROUND

The general surgery results of the West African College of Surgeons (WACS) post-graduate fellowship examination could not be regarded as satisfactory when compared with the results of similar post-graduate examinations in some developed countries. For example the pass rate of the West African College of Surgeons examination was usually under 40% whereas the pass rate in oral examination in a similar post-graduate examination, the American Board of Surgery was 84% in 2006, 73% in 2012. The first time pass rate in general surgery of final year general surgery residents at the American Board of Surgery qualifying and certifying examinations were 74% - 78% between 2000 and 2007.

AIM & OBJECTIVES

To identify the factors responsible for the high failure rate at the general surgery fellowship examinations of the West African College of Surgeons.

STUDY DESIGN

Descriptive study .We studied and analyzed the West African College of Surgeons examination results for April 2012, October 2012, April 2013 and October 2013 with emphasis on the results, the conduct of the examination and the opinion from fellows about the examiners. Well structured questionnaires were sent to fellows who had passed all the various fellowship examinations of the West African College of Surgeons in general surgery to indicate their opinion about the examination, and the examiners.

SETTING

University College Hospital, Ibadan, and Jos University Teaching Hospital, Jos, Nigeria.

METHODOLOGY

The first part of the study dealt with an analysis of each section of the examination prospectively studied over a 2-year period. This consisted of four sets of examination results. The second part was a questionnaire-based study administered to Fellows who had passed the WACS final fellowship examination in general surgery. The questionnaire had three sections: primary, part 1 and part 2 and included basic demographics, date at attempts in each grade of the examinations and the outcome. It also included the views of the respondents on the conduct of the examination and outcome. The data were analyzed using Microsoft Excel.

RESULTS

A total of 720 candidates with age range of 28 - 39 years and a mean of 33.2 years sat for the Part 1 Fellowship examinations in 2012 and 2013 with an average of 180 candidate per examination. At the Part 2 fellowship examination, 84 candidates with the age range of 31 - 42 year and a mean of 36.5 years sat the Part 2 Fellowship examination with an average of 21 candidates for each Part 2 examination in general surgery during the same period. The examinations held in April and October of each year. While an average of 28.8% of the candidates passed, an average of 71.2% of the candidates failed the Part 1 Fellowship examinations in 2012 and 2013. The aggregate clinical score was responsible for failure in 59.5% of the candidates. In the Part 2 Fellowship examination in general surgery during the same period, 31.5% of the candidates passed while an average of 68.5% of the candidates failed per examination. The aggregate clinical score was responsible for 53.3% of the candidates who failed the Part 2 examination. Furthermore, 60 - 69.7% of the candidates had a favourable opinion about the conduct of the examination, 54.5 - 63.6% rated the professionalism of the examiners high, even though the pass rate at the first attempts of the various grades of the examination by the respondents was about 50 percent.

CONCLUSION

The clinical part of the examination is a major factor responsible for the high failure rate in the general surgery fellowship examinations of the West African College of Surgeons. In order to mitigate this, residents in training should be exposed to the clinical management of a wide range of cases in the discipline with majority of the operations performed by them under the direct supervision of their consultants.

Management of the mass casualty from the 2001 Jos crisis

BACKGROUND

We report our experience in the hospital management of mass casualty following the Jos civil crisis of 2001.

MATERIALS AND METHODS

A retrospective analysis of the records of patients managed in the Jos civil crisis of September 2001, in Plateau State, Nigeria. Information extracted included demographic data of patients, mechanisms of injury, nature and site of injury, treatment modalities and outcome of care.

RESULTS

A total of 463 crisis victims presented over a 5 day period. Out of these, the records of 389 (84.0%) were available and analyzed. There were 348 (89.5%) males and 41 females (10.5%) aged between 3 weeks and 70 years, with a median age of 26 years. Most common mechanisms of injury were gunshot in 176 patients (45.2%) and blunt injuries from clubs and sticks in 140 patients (36.0%). Debridement with or without suturing was the most common surgical procedure, performed in 128 patients (33%) followed by exploratory laparotomy in 27 (6.9%) patients. Complications were documented in 55 patients (14.1%) and there were 16 hospital deaths (4.1% mortality). Challenges included exhaustion of supplies, poor communication and security threats both within the hospital and outside.

CONCLUSION

Most patients reaching the hospital alive had injuries that did not require lifesaving interventions. Institutional preparedness plan would enable the hospital to have an organized approach to care, with better chances of success. More effective means of containing crises should be employed to reduce the attendant casualty rate.

HIRSCHSPRUNG'S DISEASE IN AN ADULT: A CASE REPORT

Hirschsprung's disease in the adolescents and adults is not a common diagnosis in our environment. However this may be as a result of misdiagnosis or late presentation as is the case with other causes of recurrent constipation in older age groups. We present a case of a 19-year old male who presented with recurrent episodes of constipation from infancy with none requiring any intervention except for the index presentation that lasted for 3 weeks with associated progressive abdominal distension. Diagnosis was made with a barium enema and full thickness rectal biopsy. He had staged procedures with an initial divided colostomy thereafter followed by a definitive Souave endorectal pull-through with a good short-term outcome.

What should constitute the clinical component in fellowship examinations in surgery

The consensus of opinion is that in all medical examinations, a failure in the clinical aspect of the examination automatically means a failure in the whole examination regardless of what the total score may be. But opinion differs as to what constitutes the "clinical aspect" of the examination. Some think it should be the average score of only long case and short cases. Others think it should be the total score of long case, short cases and viva voce. Yet others think when the orals are of two parts it should be the average score of long case, short cases and a part of the orals. We therefore used the result of 197 surgical residents that sat for the part 1 fellowship examination of the West African College of Surgeons in April 2012 for this study. We collated the scores of various categories of clinical aspect of the examination to see whether there is any difference in the pass rate of the group.

The evolution of surgical procedures in the management of duodenal and gastric ulcers

Surgical procedures for the surgical management of duodenal ulcer had evolved through many stages, over the years. It started with gastroenterostomy alone, then followed by subtotal gastrectomy, vagotomy alone, vagotomy and gastro-jejunostomy, vagotomy and pyloroplasty, and highly selective vagotomy - all which started as open surgical procedures. Now unless there are complications the treatment is essentially medical following the work of Marshall and Warren. Currently, even when surgery is indicated, minimal invasive procedures are preferred. Four main types of pyloroplasties are well known. They are Weinberg, Heinecke-Mikulicz, Finney and Jaboulay. Vagotomy can be truncal, selective, and highly selective. Accepted surgical treatment for gastric ulcer is the distal gastric resection to include the ulcerated area, but not resecting more than 50-60% of the stomach. In the uncommon cases of Zollinger-Ellison syndrome, aggressive gastric surgery, the use of drugs, and the resection of the tumour have all been recommended in appropriate cases. With the discovery of Helicobacter pylori and its effective medical treatment, surgery has little role in the initial management of peptic ulcer disease. The place of the history of the surgical procedures employed earlier in the treatment of this disease would remain relevant.

Traumatic Intracranial Aerocele With Progressive Blindness - A case report

BACKGROUND

Traumatic intracranial aerocele, also known as pneumocephalus, is an uncommon condition that may be asymptomatic or may present with progressive neurological deficits and life threatening conditions that demand urgent decompressive craniotomy to reduce the acute rise in intracranial pressure and the sequelae.

AIMS & OBJECTIVES

A high degree of suspicion and continuous neurological monitoring are essential for the early detection and the prompt neurosurgical intervention demanded for the achievement of a good outcome in patients following traumatic acute severe head injury with life threatening neurological complications.

METHOD

Presentation of a young motorcyclist who was not wearing a crash helmet and was involved in a road traffic accident in which he sustained a compound cranio-facial injury with loss of consciousness and symptomatic intracranial aerocele.

RESULTS

The case of a 28-year old motorcyclist without a helmet, following a road traffic accident, sustained compound skull fracture with CSF rhinorrhea, ventricular aerocele and progressive blindness who recovered his vision fully following bitemporal decompressive craniotomy.

CONCLUSION

A high index of suspicion enabled early detection and prompt decompressive craniotomy that stemmed the progressive loss of vision in this patient with an uncommon but symptomatic intracranial aerocele and cranio-facial compound head injury.

Fracture of the penis. A report of two cases

We present two cases of fracture of the penis in two young men at the extremes of the social strata the first an unemployed tailor while the other a practicing engineer. The first one was a bachelor while the other was married with children. In the first case, the fracture occurred during masturbation while in the second case it occurred during consensual intercourse with his wife on top. In the first case the fracture occurred at the base of the penis with associated rupture of the deep dorsal vein while in the second case it affected the mid-shaft with urethral rupture and blood at the tip of the penis at presentation. Both of them presented within two hours of their injuries with deformed, swollen and tender penis. Laubscher's subcoronal sleeve operation with evacuation of clots and repair of the tear with absorbable sutures to ensure a leak-proof repair was promptly performed with no complications. Both patients experienced spontaneous erection whilst in hospital even with indwelling catheter in place. The wife of the second case became pregnant six months after the repair. Counseling was successful with the engineer but was unsuccessful with the tailor-bachelor who continued with masturbation despite professional help. Though we published the first case of fracture of the penis in this centre almost a decade ago, we still found it necessary to report these new cases managed after we created awareness of this uncommon condition in our environment in order to highlight the presentations and the factors that influenced outcome.

Arrow-chest injuries in north central Nigeria: case series

BACKGROUND

Metal arrows are still used in communal conflicts on the Jos Plateau in the north central region of Nigeria, even at the turn of the 21st Century with yet undetermined pattern and outcome.

OBJECTIVE

To determine the pattern of the injuries and the factors that influence the outcome of this uncommon condition.

METHODS

A prospective study of nine patients managed over a 6-year period. Information obtained on each patient included sex, age, site of and event leading to the injury, treatment offered and its outcome. The data were analyzed using Microsoft Excel Software.

RESULTS

Nine cases of metal tipped arrow chest injuries are reported. They were all males. Six (67%) cases arrived at the Accident & Emergency Department alive with the arrows partly or completely in the chest. Three cases died in the field of combat giving a mortality rate of 33. The other six (66.6%) were received alive. All the six (67%) had emergency thoracotomy and all of them survived with two (22%) morbidities. In five (56%) cases, including the three dead cases, the arrows were partly inside the chest and partly protruding outside while in four (44%) cases the metal arrows were completely inside the chest. The left hemithorax was more commonly involved with 6 (67%) cases, 2 (22%) on the right and the manubrium sterni in one (11%) case. The associated injuries were arrow injury of the thigh in one (11%) patient and Colles fracture in two (22%) patients. Hospitalization period ranged between 10 to 18 day while mortality was 33% and morbidity was 22% as a result of wound infection.

CONCLUSION

Arrow chest injuries on the Jos Plateau result from communal conflicts among young male adults. Emergency thoracotomy resuscitation produce good outcome in majority of the patients. Bow, arrows and crossbows should be banned as weapons, and instruments for hunting and sports.

Thyroidectomy under local anaesthesia: how safe?

BACKGROUND

In order to compliment the inadequate health facilities in the rural areas in Nigeria, nongovernmental organisations provide adhoc outreach health camps that offer treatment in various medical specialties including surgery.

SETTING

Rural outreach health camps.

OBJECTIVE

To evaluate the safety of thyroidectomy under local anaesthesia at rural outreach setting with inadequate facilities for general anaesthesia.

PATIENTS AND METHODS

This was a prospective descriptive study of 33 consecutive cases of thyroidectomy performed using field block with 1% lignocaine and adrenaline 1: 200,000 dilution during two free medical outreaches that held at Jos, Nigeria in March and October 2005 respectively, lasting two weeks each.

RESULTS

A total of 33 primary thyroid operations were performed consisting of 30 subtotal thyroidectomies (91%), 2 lobectomies (6%) and one total thyroidectomy (3%), The patients were aged between 23 and 62 years with a mean age of 45.8 years. There were 3 males and 30 females with a male: female ratio of 1:10. There was no mortality but morbidity was 2/33 (6%) Two complications were recorded in 2 patients and were superficial surgical site infection (3%) and reactionary haemorrhage (3%).

CONCLUSION

We conclude that thyroidectomy under local anaesthesia is a safe procedure in experienced hands at rural settings with inadequate facilities for general anaesthesia.

Ileosigmoid knotting--a case for primary anastomosis

BACKGROUND

Resection of gangrenous/non-viable bowel followed by primary anastomoses is known to be a viable option for treatment of ileosigmoid knotting. We here report a case of ileosigmoid knot and examined the options for treatment.

METHOD

A case report of a patient with ileosigmoid knotting and discussion of relevant literature for surgical treatment.

RESULT

A 26 year old man presented to the accident and emergency unit with two weeks' history of fever and alternating diarrhea and constipation followed by features of intestinal obstruction and later, generalized peritonitis. Plain abdominal X-rays showed dilated loops of bowel and multiple air-fluid levels. The diagnosis of ileosigmoid knotting was missed preoperatively. At exploratory laparotomy, ileosigmoid knot was encountered with non-viable segments of the sigmoid colon and ileum. Resection of the non-viable bowel was carried out with primary anastomoses with good postoperative outcome.

CONCLUSION

Primary anastomoses after resection of gangrenous bowel is a safe surgical treatment option in ileosigmoid knotting.

Medicolegal autopsies in North Central Nigeria

OBJECTIVE

To determine the pattern and the causes of deaths reported to the coroner for medicolegal autopsies in North Central Nigeria.

DESIGN

A descriptive retrospective study.

SETTING

Jos University Teaching Hospital, Jos, Nigeria between January 1996 to December 2003.

SUBJECTS

Autopsies reports of 279 subjects whose causes of death were subjects of litigation.

MAIN OUTCOME MEASURES

The causes of death in medicolegal autopsies.

RESULTS

A total of 279 cases of medicolegal autopsies with identified causes of death were recorded representing 89% of all the autopsy examinations performed within the period. In 7.6% of cases, there was no identifiable cause of death. There were 127 males against 52 females with a male: female ratio of 4.5:1 and their ages ranged between two and 74 years with a mean of 34.7+/-8.2 years. Children aged < 15 years made up 29% of the cases and were distributed as follows: 4% of the children were aged 0-5 years, 9% between six to ten years while 17% were between 11 - 15 years. Accidental deaths made up 51% of the cases, homicides 36% and sudden deaths 13%. Road traffic accidents were responsible for 76% of all accidental deaths. Children were affected in 34% of the accidental deaths and half of them were pedestrians at the time of accident. The male: female ratio of deaths from road traffic accidents was 3:1 with mean age of 24 years. In all the accidental deaths, abdominal injuries were responsible for 47% while 30% died from chest injuries. Of the homicide cases male subjects outnumbered female in a ratio of 16:1 and children were affected in 28% of homicides. Injuries sustained during ethnic and religious crisis were responsible for 48% of the deaths from homicide and 15% of them were children. Armed robbery was responsible for 28% cases while physical assaults were responsible for 20% of homicides. Chest injuries were the causes of death in 54% and abdominal injuries in 36% of homicides. Cardiovascular deaths were responsible for 63% cases of all sudden natural deaths referred for Coroner's inquest during the period. Children made up 11% of all sudden natural deaths. Males outnumbered females in cardiovascular deaths in a ratio of 6:1 and 46% cases of them died of hypertensive heart failure, 32% had cerebrovascular accidents, pulmonary embolism in 13.6% and myocardial infarction in 9%. One case of myocardial infarction died during intercourse.

CONCLUSION

Road traffic accidents, violent communal unrest and armed robbery were responsible for 66% of the medicolegal autopsies in our environment. Public enlightenment, good road maintenance and safe driving culture as well as sustainable security for life and property would reduce the incidence of preventable deaths.

A four-year analysis of manuscripts submitted for publication in West African Journal of Medicine (June 2001 to May 2005) (a brief report)

There are various criteria that could be used to rate a tertiary institution. One of these is the productivity of the members of staff which is shown by the research conducted, publications submitted and manuscripts published in indexed journals. Manuscripts submitted and published in one of the highly rated indexedjournals in our locality were analysed with a view to identifying how the institutions add to knowledge by their contributions. Our findings show that the four top-rated institutions in terms of manuscripts published in West African Journal of Medicine (WAJM) are University College Hospital (UCH), lbadan, University of Ilorin Teaching Hospital (UITH), Obafemi Awolowo University Teaching Hospital (OAUTH), and Jos University Teaching Hospital (JUTH).

HIV and hepatitis B seroprevalence in trauma patients in North Central Nigeria

BACKGROUND

With the high prevalence rate of HIV and Hepatitis B virus infections in sub-Saharan Africa, infected surgical patients, especially those with fresh open wounds, pose significant danger of occupationally-acquired infections to health workers.

METHOD

A two-year double blind study aimed at determining the seroprevalence rates of HIV and Hepatitis B virus infections among trauma patients with fresh open wounds in North Central Nigeria.

RESULTS

There were 134 patients with fresh open wounds in this study; their ages ranged between 17-80 years with a mean of 30.9 +/-9.6 years and the male:female ratio was 5:1. All the patients were tested for both HIV and Hepatitis B virus infections. Six(4.5%) patients were positive for HIV-1 while 95(70.9%) patients were positive for Hepatitis B. In all, 3(2.2%) male and 3(2.2%) female patients tested positive for HIV-1 while 77(57.4%) males and 18(13.4%) females tested positive for Hepatitis B; 5(3.7%) patients tested positive for both HIV and Hepatitis B. Though every social class was represented, HIV infection rate was higher in Social Class V than in Social Class 1 but the class incidence rate for Hepatitis B was about the same ranging between 1.2 and 1.6 for both the upper and lower classes. The significance of this study was that the incidence of Hepatitis B virus infection in trauma patients was remarkably higher than the incidence of HIV infection. The implication is that emphasis on control of exposure of health care workers to blood borne infections in the workplace should be as strong for Hepatitis B virus infection as it is for HIV.

CONCLUSION

The main finding of this study was the determination of the seroprevalence of HIV and Hepatitis B virus infections in trauma patients with open wounds which underpinned the dangers they pose to health care workers.

Clinicopathological features and molecular markers of breast cancer in Jos, Nigeria

BACKGROUND

Several studies have suggested that breast cancer in black women is associated with aggressive features and poor survival. This study examines molecular markers along with clinical stage and pathological grade in breast cancer material from Jos, Nigeria.

STUDY DESIGN

The histological diagnoses of 178 consecutive Nigerian patients with breast cancer were retrieved from their hospital records. A subset of 36 patients was staged and their tumours typed and graded. Immunohistochemical staining of sections from paraffin wax embedded tissues from these cases for the expression of oestrogen receptor (ER), progesterone receptor (PGR), Human ERBB2 (or HER2/neu), p53 and cyclin D1 (CCND1) was carried out using the avidin biotin complex (ABC) procedure.

RESULTS

A majority of the cases were invasive ductal carcinoma (92.7%), high grade (grade 3, 70.6%) and of late clinical stage (stages III and IV, 58.3%). Only 25% and 27.8% of cases expressed ER and PGR respectively. The ERBB2 and CCND1 antigens were expressed in 25%, and 5.7% of cases respectively. The p53 protein was the most frequently expressed in this study (47.2% of cases). High grade tumours were significantly more likely to be ER and PGR negative (P = 0.006 and P = 0.002 respectively). CONLCLUSION: There is predominance of high grade, invasive ductal carcinomas which are likely to be ER and PGR negative but p53 positive. These features suggest a biologically aggressive form of breast cancer in Nigerian women with the possibility of poor response to both hormonal therapy and chemotherapy.

Typhoid intestinal perforation in north central Nigeria

BACKGROUND

Typhoid intestinal perforation is a surgical problem with severe morbidity and high mortality in North Central Nigeria.

PATIENTS AND METHODS

In order to determine the pattern and the prognostic indices, we studied 101 patients with typhoid intestinal perforation managed over a ten-year period

RESULTS

Children constituted 49% of the cases and majority (78%) of the patients were in the low socio-economic strata. The incidence peaked to 67% between November and March - the dry season in Nigeria. The male/female ratio was 1.9:1 with a mean age of 19 years and a mean hospitalization period of 18 days. There were 167 perforations; four involved the large bowel and appendix, and in 72.2% cases, the perforation was single. The mortality rate was 13.9%, affected mostly children and significantly worsened by prolonged perforation-surgery interval > 72 hours, jaundice, convulsion, ASA V, faecal peritonitis and re-exploration for early intra-peritoneal complications. Morbidity rate was 65.3% and significantly affected more children than adults and associated with perforation-surgery interval of between 24 and 72 hours, haematochezia and multiple perforations. Moribund patients fared better when operated upon under local anaesthesia with adequate analgesia. The least traumatic but effective surgical procedure that could seal the perforations and keep the peritoneum clean gave the best results. Children who survived up to 5 days and adults who survived up to 10 days after surgery had better chances of survival.

CONCLUSION

The most significant prognostic factor is late presentation which prolongs perforation-surgery interval and the other complication and mortality indices are directly influenced by it.

Male breast malignancy in Jos University Teaching Hospital

BACKGROUND

Male breast malignancies are rare. Cancer of the male breast accounts for about 1% of all breast cancers. Poor level of awareness often results in late presentation and delayed diagnosis in our environment.

PATIENTS AND METHODS

A retrospective study of all cases of male breast cancer (MBC) managed in Jos University Teaching Hospital over a 17-year period (January 1987-December 2003.)

RESULTS

A total of 302 cases of breast malignancies were managed over the study period. Twenty-six (8.6%) of these were males giving a male:female ratio of 1:10.6. The ages of the 26 MBC cases ranged from 12 years to 85 years, with a mean of 57.9 years and median age of 67 years. The right breast was affected in 15 and the left in 11. Mean duration of symptoms before presentation was 6 months with a range of 3 months to 4 years. All the patients had history of breast lumps, 21 (80.8%) of which were painless. Skin ulceration and axillary node enlargement were present in 19(73.1%) and 24(92.3%) respectively. Five (19.2%) were stage II; 15(57.7%) stage III and 6(23.1%) stage IV. There were 23 (88.5%) carcinomas, 2 (7.7%) fibrosarcomas and a case of Hodgkin's lymphoma. Invasive ductal carcinoma was the most common histological type in 20 (76.9%) of all breast malignancy and 20 (87.0%) of all breast carcinomas. Modified radical mastectomy (mastectomy with axillary clearance with or without division of the pectoralis minor muscle) was done in 10(38.5%) patients. Two of these were fibrosarcomas. Simple mastectomy was done in 13 (50%) as toilet procedures for advanced disease. The only case of Hodgkin's lymphoma had chemotherapy. Bilateral orchidectomy (BO), Tamoxifen, chemotherapy and radiotherapy were offered in 7(26.9%), 13(50%), 17(65.4%) and 7(26.9%) patients respectively. Wound infection was the most common complication in 14(53.8%) patients. There was no case of hospital mortality.

CONCLUSION

MBC accounts for 8.6% of all breast cancers in our centre. It affects elderly males. Late presentation with advanced disease and ulceration is a common feature in our environment.

Testicular torsion on the Jos Plateau

In order to determine the pattern and the factors that influenced outcome, we retrospectively studied fifty-seven patients with torsion of the testis admitted to the Jos University Teaching hospital between August 1993 and July 2001. The age ranged from 2 to 55 years with a mean of 22.7 years. Majority (79%) of the patients were in the second and third decades of life. The main suspected precipitating factors in this study were cold weather and scrotal trauma: in 28% of the cases no cause could be ascertained. Eight (14%) patients presented within 4 hours and 35 (61%) presented after 24 hours of the onset of symptoms. Both sides were equally affected. Testicular pain, retraction and scrotal swelling were the most common presenting complaints. The highest incidence 65%) occurred between November and February when the weather on the Jos plateau is coldest. At surgery, 34 (60%) patients were found to have associated congenital anomalies; in 22 (39%) patients, the testis was non-viable. There was no mortality in this series and the complications were superficial wound infection (14%), testicular atrophy (7%) and sub-fertility (16%). High index of suspicion in a patient with acute scrotum, prompt and effective surgery will improve testicular salvage.

Acalculous cholecystitis in Nigerian children

Sixteen children with acalculous cholecystitis (AC) were treated over a 9-year period (13 male and 3 female). Their ages ranged from 8 to 18 years (median 11). Eight (50%) presented with complications (perforation 4, gangrene 2, empyema 2); 13 (80%) presented with acute AC with a duration of symptoms of 2 weeks or less while 3 (20%) presented with chronic AC with symptoms present for more than 3 months. The diagnosis was made by ultrasound except in the patients with complications, who were diagnosed at laparotomy. Salmonella typhi was cultured in the bile and blood in 2 cases and the Widal titre was significantly elevated in 4 others. One child had chronic blockage of the cystic duct by a lymph node; in 9 there was no identifiable cause. Open cholecystectomy was successfully performed in 15 cases, while 1 child was managed non-operatively. The need for early diagnosis of cholecystitis in children is obvious if the potentially life-threatening complications of perforation and gangrene are to be avoided.

Marfan's syndrome presenting with abdominal aortic aneurysm: a case for vigilance

We present the case of a 16-year old student with Marfan's syndrome and abdominal aortic aneurysm who presented with a diagnostic conundrum. He presented with a three months history of progressive painful left upper abdominal mass and back pain. It became severe in the last two weeks before presentation and was associated with constipation. This mass was thought to be of splenic origin but the initial ultrasound suggested a pancreatic pseudocyst. Review of his previous hospital record revealed that he had been treated for severe myopia which started at infancy. Another opthalmic review at our centre revealed bilateral ectopia lentis. He had no cardiac signs and no family history of cardiovascular diseases. He is the 6th of 8 siblings, all the family members are alive and healthy except one sibling who died at 7 months. The diagnosis of abdominal aortic aneurysm was only made at laparotomy and confirmed by on-table aortogram. He had excision of the aneurysmal sac and replacement with on-lay dacron tube graft. He died on the 4th post-operative day. A diagnosis of abdominal aortic aneurysm was not made at initial presentation because of the rarity of this condition in our environment and incompetence of the ultrasonographer. Aortic aneurysm in Marfan's syndrome is commonly found in the thoracic part of the aorta, however in this case, it is abdominal. A high index of suspicion is necessary to avoid missing this pathology, therefore the need for vigilance.

Cleft lip and palate: the Jos experience

OBJECTIVE

To determine the pattern of occurrence of cleft lip/palate and the factors that may have influenced treatment outcome.

DESIGN

Descriptive Study.

SETTING

Jos University Teaching Hospital, Jos, Nigeria.

SUBJECT

This study included 107 consecutive patients with cleft lip/palate managed between January 1991 and June 1997.

MAIN OUTCOME MEASURES

The pattern of occurrence of cleft lip/palate, the peculiarities of the malformation in this environment as well as factors that influenced treatment outcome.

RESULTS

The 107 patients were aged between one day and twenty-six years at presentation. There were three adults aged between 18 and 26 years with a mean of 22.3 years and 104 children with a mean age of 9.5 months. The male/female ratio was 1. 1:1, the anomaly was 2.4 times commoner on the left and the cleft lip alone was the most frequent mode of presentation (52%). The incidence was higher in the 3rd and 4th siblings. In 13% of these patients, there were other associated congenital anomalies such as Van der Woude's Syndrome, Down's Syndrome and congenital heart disease. Complications were noted in 16(14.9%) patients and these included dehiscence after repair in 8(7.5%) patients, oronasal fistulae in 2(1.9%), nasal speech in 4(3.7%) and hypertrophic scar in 2(1.9%). Eighty nine percent of these repairs were satisfactory to the parents of the affected children. All the adult patients were satisfied with their repair.

CONCLUSION

The low incidence of this anomaly in our environment may be due to underreporting in the rural areas. Public enlightenment programs should help improve early presentation.

Adult intussusception: the Jos experience

Twenty two consecutive cases of adult intussusception managed between January 1990 and December 1998 at Jos University Teaching Hospital formed the basis of this study. Thirteen (59.1%) of the patients were males and 9(40.9%) females, with a male to female ratio of 1:4:1 and a mean age of 49.6 years. Most patients were referred late to our service as a result of poor index of suspicion and misdiagnosis. Laparotomy was done in all the cases and in 5(22.7%) patients no cause could be found, but in the remaining 17(77.3%) definite causes were identified which were mainly polyps in 7(31.8%) patients and colonic malignancies in 4(18%). The ileocolic intussusception was the commonest variety. Sixteen (72.7%) patients had bowel resection for colonic carcinoma, gangrenous bowel and irreducibility of the intussusception while manual reduction was successful in the other 6(27.3%) patients. The morbidity rate was 22.7% and the complications were wound infection and adhesive intestinal obstruction. Two deaths were recorded with a mortality rate of 9.1%. The pattern of adult intussusception as seen in the western world was observed in this tropical highland.

Acute haemorrhagic pancreatitis in HIV positive patients

We present two cases of severe acute haemorrhagic pancreatitis (1,2), in otherwise healthy adults who were HIV positive. Acute pancreatitis is not known to be common in the African communities but the incidence is on the increase (1). Both of them scored between 5 and 6 points on the Ransom scale (3). One of them died despite similar aggressive resuscitation, adequate transfusion with fresh frozen plasma (4,5) and peritoneal lavage (6,7,8) Though Steinberg and Tenner (2) had shown a higher incidence (4-22%) of acute pancreatitis among patients with the acquired immune deficiency syndrome (AIDS) in some populations, we are not aware of any observation in literature that same is true in otherwise healthy patients who are HIV positive. We are posting that what we have observed may indeed be human immune deficiency viral haemorrhagic pancreatitis. A prospective study of patients with acute pancreatitis will determine the position.

Van der Woude syndrome with mental retardation: case report

A report of a four and half-year old African patient with Van der Woude syndrome and mental retardation is reported. In addition to cleft lip/palate, hypodontia and lower lip pits; features consistent with Van der Woude syndrome, he manifested features consistent with growth and mental retardation. A genetic basis for these associated features can only be determined by detailed karyotype studies.

Intra-operative cardiac arrest--a tropical experience

In order to determine the pattern of intra-operative cardiac arrests in a developing country, we reviewed 40 consecutives cases of cardiac arrests at the Jos University Teaching Hospital between January 1993 and December 1997. During this period 15,060 minor cases and 9800 medium/major surgical procedures were performed and an arrest rate of 1:15,060 for minor cases and 1:251 for medium/major cases were obtained. The age ranged between one day and 65 years with a mean of 29.8 years and a male/female ratio of 1:1.3 as there were 18 males and 22 females. Twenty-five (62.5%) arrests occurred outside work hours while fifteen (37.5%) cases arrested during work hours. The surgical procedures with high arrest rates in this study were: emergency laparotomy 8 (20%), emergency caesarian sections 7 (17.5%), thoracotomy 6(15%), emergency craniotomy 5(12.5%), emergency hysterectomy 4(10%) and therapeutic bronchoscopy for foreign bodies in the airway 4(10%). The arrests occurred in 30(75%) emergency procedures as opposed to 10(25%) elective cases. Only in 3 out of the 18, 318 day case procedures did the patients arrest. One patient arrested during local infiltration of lignocaine while the other 39(97.5%) arrested under general anaesthesia. There was no arrest with spinal anaesthesia. The predisposing factors for a patient to arrest on the operating table in our environment include emergency major surgery, poor risk patients with ASA 111 and above, surgery performed outside work hours, under general anaesthesia administered by nurse anaesthetists or junior anaesthetic residents. The success rate at resuscitation is highest with patients with ASA 1 & 11, operations performed during work hours and by senior surgeons and anaesthetists.

Childhood intussusception: a 9-year review

Sixty-four consecutive cases of intussusception in 48 infants and 16 older children managed at Jos University Teaching Hospital between January 1990 and December 1998 are reviewed. The age range was between 3 months and 15 years (mean 2.2 years) and the male to female ratio was 3.6:1. The quartet of abdominal pain, bloody mucoid stools, abdominal mass and palpable rectal mass was present in 70% compared with the classical triad (abdominal pain, bloody mucoid stools and abdominal mass) which occurred in only 32%. All the children had surgery. In 26 (41%) of the children, no associated cause was found, in three polyps formed the lead point and in five children a buried appendicectomy stump formed the lead point. In 30 (47%) other children, mesenteric lymphadenopathy and inflamed Peyer's patches were noted. Ileo-colic intussusception occurred in 32 (50%) children. Manual reduction was successful in 67%. Bowel resection for gangrene, irreducibility and an iatrogenic colonic tear was done in 30% of patients. Two (3%) had spontaneous reductions. There were four deaths. The commonest complications were wound infection and adhesive intestinal obstruction.

Chronic osteomyelitis in patients with sickle cell disease

OBJECTIVE

To determine the baseline pattern and audit management modalities of chronic osteomyelitis in patients with sickle cell disease.

DESIGN

A retrospective study.

SETTING

Jos University Teaching Hospital, Jos, Nigeria from August 1993 to July 1997.

PATIENTS

Twenty four patients with concomitant chronic sickle cell disease.

INTERVENTIONS

Fifteen patients had operations; eleven had sequestrectomy and curettage while four had incision and drainage. Eight patients were treated with antibiotics alone and one patient refused surgery.

MAIN OUTCOME MEASURES

The demographic data of patients, aetiological agents, culture and sensitivity patterns, aetiopathogenesis, treatment modalities and outcome were analysed.

RESULTS

Twenty four (36.9%) out of 65 patients who had chronic osteomyelitis also had sickle cell disease. Male:female ratio was 1.2:1. The peak age incidence (37.5%) was in the first decade of life. Seventy five per cent of infections were haematogenous. The most frequently isolated organism was Staphylococcus aureus (58.8%) while the rest were Gram negative organisms. There was no case of Salmonella osteomyelitis. The most sensitive antibiotics were gentamicin and the third generation cephalosporins. Twelve patients (50%) had good results while eight (33.3%) were still undergoing treatment. Complications recorded were persistent discharging sinuses in two cases, recurrence of symptoms in one and pathological fracture with non-union in one patient.

CONCLUSION

Though the incidence of Gram negative organisms in causation of chronic osteomyelitis in patients who have sickle cell disease is high (41.2%), Salmonella osteomyelitis may be related to endemicity of the organism in a given locality.

One-stage procedure in the management of acute sigmoid volvulus

In a descriptive prospective study, twenty-seven patients with sigmoid volvulus and three with ileosigmoid knotting had primary resection of the redundant sigmoid colon with immediate anastomosis after intraoperative antegrade colonic irrigation. There was no clinical anastomotic leak nor mortality in any of our patients. Superficial wound infection occurred in four patients (13.3%). Intraoperative colonic irrigation time ranged between 25 to 50 minutes with a volume of saline/Hartmann's required to achieve a clean colon ranging between 1.5 to 5.0 litres. The duration of hospital stay ranged between 7 and 14 days. The result of this study suggests that resection of acute sigmoid volvulus and primary anastomosis after antegrade intraoperative colonic lavage is safe provided the patient is reasonably fit.

Comparative study of conservative resection and radical operation for thyroid carcinomas

OBJECTIVE

To compare mortality and morbidity in management of thyroid cancers by total lobectomy (C-R) and near-total thyroidectomy (R-O) and to relate pathological subtype to prognosis.

DESIGN

A retrospective study of patients with thyroid cancers that were managed during an eleven-year period.

SETTING

Jos University Teaching Hospital, Nigeria.

SUBJECTS

A total of 44 patients who underwent C-R (n = 26) and R-O (n = 18) were studied.

INTERVENTION

A total of 509 goitrous specimens including the excised thyroid cancers were histopathologically studied.

MAIN OUTCOME MEASURES

Cases were analysed for mortality and morbidity data in the two groups during a partial follow-up period of two years.

RESULTS

Mortality figures for C-R was 4% versus 11 for R-O. Postoperative haemorrhage occurred in 14% for C-R versus six for R-O. Similarly, bilateral vocal cord paralysis occurred in 11% versus 22; voice changes in 11% versus 33, transitory hypoparathyroidism 8% versus 50, local recurrence in 18% versus eleven. Hypothyroidism occurred in all patients undergoing R-O and stitch granuloma in 11% of patients in C-R group versus six for R-O. Follicular carcinoma constituted 59% of the total number thyroid cancers with papillary cancer constituting 35%.

CONCLUSION

C-R is recommended as the operation of choice for thyroid cancers.

Spinal injuries in the Plateau State, Nigeria

OBJECTIVE

To highlight the epidemiology, management and outcome of spinal cord injuries (SCI) in the Plateau State of Nigeria.

DESIGN

A retrospective study involving case note analysis of all patients with SCI admitted into the hospital.

SETTING

The study was carried out at the Jos University Teaching Hospital to cover January 1984 and December, 1997.

SUBJECTS

Sixty eight cases of SCI were studied.

INTERVENTIONS

Patients were managed by conservative and operative interventions especially in cervical subluxations involving C5 on C6.

MAIN OUTCOME MEASURES

Neurological function was assessed employing Frankel scale.

RESULTS

There was an increased hospital incidence for SCI between 1994 and 1997. Means age of presentation was 30 years and sex ratio M:F was 10:1. Vehicular accidents accounting for 49 per cent of SCIs and collapsed tunnels (26 per cent) were the two common causes. Fracture dislocation of the spine (unstable) occurred in 52 per cent and flexion wedge fractures (stable) in 14 per cent. Ten per cent of patients had no neural deficits at presentation, 21 per cent had partial cord lesions and 69 per cent complete cord lesions. Hospital mortality was 26 per cent. The four patients subjected to posterior spinal fusion, (Frankel A to E) including 8 other patients that were conservatively managed.

CONCLUSION

Centres for spinal injuries should be established incorporating hospital wards, theatres, gymnasia, nursing units, occupational therapy units, activity centres and workshops. These centres will generate comprehensive data on morbidity and morality needed for future planning.

Cordylobia anthropophaga mastitis mimicking breast cancer: case report

A case of furuncular myiasis of the breast due to infestation by the larva of Cordylobia anthropophaga in a young lady is presented. Some of the physical presentations of Cordylobia anthropophaga mastitis are similar to those of carcinoma of the breast. High index of suspicion in endemic areas, including patients who had visited such areas, the characteristic intense itching of the affected breast, the use of the magnifying hand lens and subsequent extraction of the offending maggots are the invaluable aids to diagnosis and treatment. The ulcer left on the breast after extraction of the maggot should be biopsied and the associated ill defined mass and skin changes must be seen to resolve completely before carcinoma of the breast can be safely ruled out. The various methods of extraction and the preventive measures are highlighted. Though furuncular myiasis has been reported to involve every part of domestic animals, this is the first reported case in literature involving the human breast.

Single-layer closure for typhoid perforations of the small intestine: case report

The case of a 13-year old girl who presented with generalised peritonitis, septic shock and laboratory features of perforated typhoid enteritis is presented. At laparotomy 25 perforations involving the distal jejunum and the entire ileum were noted with extensive peritoneal soilage. The perforations were successfully closed in single layer using vicryl (polyglactin 910) sutures and the peritoneum thoroughly lavaged. The patient has been followed up for thirty months with only minimal complications. We believe that single layer closure of extensive multiple typhoid perforations in a poor risk patient when weighed against resection and anastomosis with the possibility of short bowel syndrome is safer, quicker and more effective as long as the procedure is undertaken after adequate resuscitation and under appropriate antibiotic cover.

Fracture of the penis--a rare injury on the Jos Plateau, Nigeria

A case of a 37 years old veterinary surgeon who sustained right sided fracture of the base of the penis during masturbation is presented. He was seen more than 48 hours after his injury with the typical painful swelling, angulation and tenderness at the fracture site. The tear was promptly repaired using the Laubscher's subcoronal sleeve technique. He regained his ability to achieve erection on the third post operative day. This is a rare injury on the Jos Plateau--being the only documented case in 11 years in this tertiary health facility and so we consider it necessary to highlight salient points in the diagnosis and treatment. Psychotherapy was found very useful in this patient in order to wean his off masturbation especially during the immediate post operative period. His short term follow up has been uneventful; he is now able to achieve normal and straight erection and sexual intercourse without pain--a view corroborated by his wife.

An unusual chest impalement

We present the case of a 49-year old farmer, a combatant in communal clash over a piece of farmland on the Jos Plateau, who was impaled on his chest by a 13.5 cm long metal arrow, 56 hours prior to presentation. The arrow hit him tangentially on the left side of the chest and disappeared completely into his chest traversing the chest wall and lacerating the superior lingula segment of the lung but the tip of the arrow was only about 1.5 cm short of the pericardium. We are not aware of any report in literature on a patient in the West African sub-region who sustained and survived such serious chest impalement by a rigid object for more than two days before hospitalisation. Sustained public education and enforced legislature against the use of such lethal weapons will go a long way in preventing serious injuries of this nature.

Management of childhood splenic trauma--the Jos experience

We studied retrospectively 22 children who were managed for splenic injuries at Jos University Teaching Hospital between September 1988 and October 1995. Sixteen were males and six were females (M:F = 2.7:1) with their ages between five and 15 years and a mean of 10.3 years. Eleven were knocked down by vehicles while crossing the freeway, playing or hawking goods; seven fell from slippery mango trees after a downpour of rain while two were passengers in a vehicle that was involved in a head-on collision and another two were kicked in the abdomen as a result of assault. All had surgery. Four sustained Uphadhyaya and Simpson's Type 1 injuries while six sustained Type IV injuries. Twelve had total splenectomy, seven had total splenectomy with heterotopic autotransplantation of splenic wafers while three had splenorrhaphy augmented with omentoplasty. An average of 1.5 units of blood per patient were transfused. There was only one death. Considering that the majority (18) of these children sustained their splenic injuries while crossing the freeway (playing or hawking goods) and from falls from mango trees after the rains, we believe that there are preventable causes. Mandatory primary and junior secondary school education as well as legislature against child labour will help keep these children safe out of harm's way and thus drastically reduce the incidence of childhood splenic injuries in our environment.

Experience in managing splenic trauma on the Jos Plateau

We studied retrospectively, fifty eight (58) patients with splenic injury admitted to Jos University Teaching Hospital between October 1988 and September, 1995. Forty-nine were males while nine were females (M:F = 5.4:1). The age ranged from 5 to 50 years with a mean of 24.5 years. The highest incidence was recorded in the third decade of life. Road Traffic Accident (RTA) was the commonest (75.8%) cause of splenic injury; others were fall from heights 7 (12.1%), blows to the abdomen 5 (8.6%) and stab wounds to the abdomen 2 (3.5%). Of the 58 cases, 56 (96.5%) were blunt abdominal injuries while 2 (3.5%) were penetrating stab injuries. All had laparotomy. 13 (22.4%) sustained Upadhyaya and Simpson's type 1 injury, 18 (31.0%) type II, 12 (20.7%) type III and 15 (25.9%) type IV injuries. Of the 58 patients, 29 (50%) had total splenectomy without heterotopic autotransplantation (HAT); 21 (36.2%) had splenectomy with HAT, while 8 (13.8%) had splenorrhaphy with omentoplasty. The average number of units of blood transfused was 2.3 units per patient. There were four (6.9%) deaths--two as a result of shock and multiple organ failure and another two died as a result of pulmonary embolism. However the commonest post operative complications were chest and wound infections. The rate of splenic salvage in this study was low despite the fact that most of these patients sustained types I and II injuries. We believe a greater salvage rate could be achieved and the trend in our centre now is toward splenic conservation.
