Fulltext Primary hyperparathyroidism--a surgical review of 12 cases

Meah FA, Tan TT, Taha A, Khalid BA

Med J Malaysia, 1991 Jun;46(2):144-9.

Twelve cases of primary hyperparathyroidism operated by the Universiti Kebangsaan Malaysia Surgical Team from 1978 to 1989 were reviewed. There was a preponderance of Indian females in this series. The majority of the cases presented late and with complications. Renal calculi and bone disease were the commonest complications noted. Of the 12 patients, 9 had single parathyroid adenoma of which 4 were ectopically located, and 2 had hyperplasia of the parathyroids. These were all successfully operated. The remaining patient had 2 failed neck explorations. Failure at initial exploration was due to ectopic location of the glands. Meticulous surgical technique, knowledge of the anatomical variations of location of the parathyroid glands and availability of frozen section facility are essential for successful outcome.

Intrasellar pituitary mucocele: diagnostic dilemma

Tang IP, Chai CK, Kumar G, Prepageran N, Waran V

Br J Neurosurg, 2014 Jun;28(3):390-2.

PMID: 23875880 DOI: 10.3109/02688697.2013.817535

Isolated intrasellar pituitary mucocele following transsphenoidal sinus surgery is extremely rare. The clinical features resemble a pituitary tumor, therefore careful radiological interpretation is crucial to reach the correct diagnosis. We report a case of intrasellar mucocele who had transsphenoidal sinus surgery performed 15 years prior.

PMID: 22390098 MyJurnal

The purpose of this retrospective joint rhino-neurosurgical study from January 1998 until September 2009 is to document the demographic data, clinical presentations, radiological findings, approaches and incidence of residual tumour. Forty-seven patients with pituitary adenoma underwent trans-sphenoidal hypophysectomy of which 25 patients with complete medical and radiological data were included in the study. The medical and radiological data were analyzed. There were 12 males and 13 females with age ranging from 17 to 76 years old (mean 49.2). Fourteen of the patients were Chinese, eight Malays and three Indians. Twelve of the patients had functioning tumour of which five each presented with acromegaly and Cushing disease respectively and two with amenorrhoea. The rest of 13 patients had non functioning tumour presenting with visual disturbances. Sixteen of the patients had pituitary macroadenomas and the rest 9 microadenomas. Eighteen patients had undergone transcollumellar trans-sphenoidal hypophysectomy and the rest 7 patients had undergone transnasal transsphenoidal hypophysectomy. About 68.8% of pituitary macroadenomas had residual tumour, compared to only 22.2% of patient with pituitary microadenomas. Radiologically, about 45.5% of residual macroadenoma had suprasellar extension and the majority had spread to suprasellar cistern and carvenous sinus (54.5%). About 16.6% of patients had undergone post operative radiotherapy. In conclusion, this study showed that patient with pituitary macroadenomas had higher incidence of residual tumour compared to pituitary microadenomas.

Fulltext Functioning adrenal adenoma in association with congenital adrenal hyperplasia

Rohana AG, Ming W, Norlela S, Norazmi MK

Med J Malaysia, 2007 Jun;62(2):158-9.

PMID: 18705452 MyJurnal

We report a case of a young hypertensive male who was first seen in 1998 with a right thalamic haemorrhage and uncontrolled hypertension. CT abdomen showed a right adrenal tumour and a hyperplastic left adrenal gland. Laparoscopic adrenalectomy performed followed by histopathological examination confirmed the diagnosis of adrenal adenoma. He subsequently presented to us again a year later with persistent hyperkalaemia and asymptomatic hyponatraemia. Further investigations strongly suggested the presence of isolated mineralocorticoid deficiency with normal cortisol levels. This was confirmed to be due to partial or late-onset congenital adrenal hyperplasia (CAH). We discuss the association of partial CAH and adrenal tumours and the unmasking of the mineralocorticoid deficiency following adrenalectomy.

Med J Malaysia, 2006 Aug;61(3):343-8.

PMID: 17240587

Surgery for pituitary tumours at our institution was performed by rhinosurgical route by combined procedure by otolaryngologist and neurosurgeons. A retrospective review of case records of patients who had endonasal endoscopic transphenoidal approach for pituitary tumours from September 1998 to December 2004 was performed. A total of 81 trans-sphenoidal surgeries were performed during this study period. Only 68 case records with adequate information were available for review, 56 patients were included in the study and 12 were excluded. There were 24 males (42%) and 32 females (58%). The ethnic distribution, were 29 Malays, 24 Chinese, 2 Indian and 1 others. The age ranged from 16 years to 76 years, with a mean of 46 years. The majority of our patients presented with visual symptoms (38), headache (28), menstrual cycle disturbance or impotence (14) and acromegalic features (16). Forty patients had macroadenoma (71%) and 16 had microadenomas (29%). Thirty-six patients out of 40 macro-adenomas had suprasellar extensions (90%). Only eleven patients had lumbar drain inserted prior to commencement of the surgery and the majority of these were macroadenomas. The common complications encountered were diabetes insipidus (4), cerebrospinal fluid leak (2), meningitis (3), epistaxis (2), septal perforation (2), intercavernous sinus haemorrhage (3) and anterior pituitary insufficiency (2). Our study reveals that endonasal trans-sphenoidal approach is a safe and effective method of management of pituitary adenomas.

Follicular adenoma with squamous metaplasia and cystic change: report of a case with fine needle aspiration cytological and histological features

Jayaram G, Jayalakshmi P

Malays J Pathol, 1999 Dec;21(2):101-4.

PMID: 11068414

Squamous metaplasia (SM) of thyroid follicular epithelium is known to occur in a variety of non-neoplastic lesions as well in thyroid neoplasms, notably papillary carcinoma (PC). In follicular thyroid tumors, on the other hand, SM is very rare. This case describes cytological and pathological findings in a follicular adenoma (FA) that presented as a cystic lesion with extensive SM. The fine needle aspiration (FNA) cytology sample in this case yielded only necrotic material from the cystic area and squamous cells, which being mostly of immature type, were not recognised as squamous in the cytological smears. The needle missed the solid (neoplastic) component of the lesion and on the whole the cytological picture was considered to be equivocal. FA can now be added to the spectrum of thyroid lesions that can show SM. Awareness of this will enable cytopathologists to consider non-papillary lesions in the differential diagnosis of thyroid nodules that yield squamous cells.

Fulltext Managing the solitary thyroid nodule

Meah FA, Qureshi MA

Med J Malaysia, 1998 Dec;53(4):453-6; quiz 457-8.

PMID: 10971996

Solitary thyroid nodules are commonly seen in surgical outpatient clinics. A detailed history and a careful physical examination are essential. In the management of the solitary thyroid nodule, fine needle aspiration cytology has become the cornerstone investigation. Ultrasound cannot differentiate between benign and malignant nodules, however is useful in the follow-up period to identify any further nodular growth. As thyroid malignancy occurs in both hot and cold nodules, radionuclide scans are not useful in the management of solitary thyroid nodules. We have attempted to outline the process of managing the solitary thyroid nodule and discuss the options available.

Standard "inject and cut" endoscopic mucosal resection technique is practical and effective in the management of superficial colorectal neoplasms

Mahadeva S, Rembacken BJ

Surg Endosc, 2009 Feb;23(2):417-22.

PMID: 18806938 DOI: 10.1007/s00464-008-9983-z

BACKGROUND: Standard polypectomy techniques may be contributing to ineffective eradication of colonic superficial neoplasia, an increasing number of which are nonpolypoid. We aimed to demonstrate the practicality and efficacy of the "inject and cut" endoscopic mucosal resection (EMR) technique in routine clinical practice.

METHODS: Colonic EMRs performed for polypoid and nonpolypoid lesions at a tertiary institution were prospectively collected and analyzed for efficacy, and short and long-term complications.

RESULTS: 224 colonic neoplasms (143 flat, 65 sessile and 16 subpedunculated) were excised by the standard inject-and-cut method, with standard accessories. The median size of all lesions was 10 mm (range 2-50 mm) and 110 (49.2%) lesions were located in the proximal colon. Histological completeness of resection was achieved in 87% of cases. Of the lesions 77.2% were dysplastic, with 5 cases of carcinoma in situ and 18 severely dysplastic adenomas. Complications included bleeding in five cases (2.2 %) and a single case of perforation (0.4%). All complications were managed endoscopically. Median follow up at 24 +/- 16 months (range 12-84 months) revealed a 7.2% local recurrence rate, all of which were subsequently eradicated by repeat EMR.

CONCLUSIONS: Standard inject-and-cut colonic EMR is practical and effective in the eradication of superficial colonic neoplasia.

A case report of primary hyperparathyroidism with severe bony involvement and nephrolithiasis

Chan SP, Hew FL, Jayaram G, Kumar G, Chang KW, Tay A

Ann Acad Med Singap, 2001 Jan;30(1):66-70.

PMID: 11242630

INTRODUCTION: Although the majority of patients with primary hyperparathyroidism have a relatively asymptomatic benign disorder, there are patients who have a more aggressive disorder.

CLINICAL PICTURE: We report a case of primary hyperparathyroidism presenting during pregnancy complicated by antepartum haemorrhage and severe prematurity. The diagnosis was made postpartum, when her problems rapidly progressed to result in severe neuromuscular weakness, bilateral pathological hip fractures as well as nephrolithiasis.

TREATMENT: Surgical parathyroidectomy was performed. The underlying lesion was a large solitary parathyroid adenoma with cystic elements.

CONCLUSION: Primary hyperparathyroidism is not an innocuous disease and can result in severe morbidity if left untreated.

Fulltext Florid papillomatosis of the nipple

Dinesh BJ, Hayati F, Azizan N, Abdul Rashid NF

BMJ Case Rep, 2019 Sep 18;12(9).

PMID: 31537599 DOI: 10.1136/bcr-2019-231516

Florid papillomatosis (FP) of the nipple, or nipple adenoma, is a rare breast tumour, affecting middle-aged group population. A 46-year-old woman presented to us with a cauliflower-like FP of the right nipple with no blood stained discharge or breast lump. FP can be mistaken clinically for Paget's disease and occasionally misinterpreted as invasive ductal or intraductal carcinoma. Extensive intervention, correct diagnosis and prompt treatment are essential. Any breast pathology requires triple assessment including FP of the nipple. Once the diagnosis of ductal carcinoma is excluded, simple complete excision can be undertaken. This is to ensure complete obliteration of disease recurrence and preservation of cosmetic result. We discuss the pathology and psychosocial aspects of FP.

Fulltext Surgical access to parapharyngeal space tumours--the Manipal experience

Hazarika P, Dipak RN, Parul P, Kailesh P

Med J Malaysia, 2004 Aug;59(3):323-9.

PMID: 15727377

A few series of parapharyngeal space tumours have been reported earlier but recently not many series have been published in English literature. It is rare for any medical center, let alone an individual surgeon, to develop sufficient experience in evaluating these tumours. We present our experience in the treatment of 41 cases of parapharyngeal tumours from January 1992 to December 2001. FNAC, ultrasound and CT scan of the presenting mass was done in most of the patients as the main pre-operative work-up. The strategic location and extension of the tumour may occasionally alter the surgical approach for tumour excision.

Fulltext Syndrome of inappropriate antidiuretic hormone caused by continuous lumbar spinal fluid drainage after transphenoidal surgery

Norlela S, Azmi KN, Khalid BA

Singapore Med J, 2006 Jan;47(1):75-6.

PMID: 16397727

A 53-year-old acromegalic woman had cerebrospinal fluid rhinorrhoea following transphenoidal surgery for a pituitary microadenoma. A continuous lumbar spinal fluid drainage catheter was inserted and on the sixth postoperative day, she developed hyponatremia with features of syndrome of inappropriate antidiuretic hormone (SIADH) requiring hypertonic saline administration. Over-drainage is potentially hazardous and close biochemical monitoring is required. To our knowledge, this is the first reported case of SIADH caused by continuous lumbar drainage in an adult.
